Each Fund is a separate, diversified investment fund of the Trust, which was
organized on October 30, 1997, as an Ohio business trust. The Trust is
registered and operates as an open-end management investment company. Each Fund
was organized for the purposes of acquiring all of the assets and liabilities of
one or more separate series of Nationwide Investing Foundation ("NIF"),
Nationwide Investing Foundation II ("NIF II") and/or Financial Horizons
Investment Trust ("FHIT") (together called the "Former Trusts"), to effect a
reorganization of each series of the Former Trusts with and into a separate
series of NIF III. Subject to shareholder approval, such reorganization is
anticipated to be completed during the first quarter of 1998. Each Fund and its
corresponding series of the Former Trust are as follows:

WHICH FUND IS RIGHT FOR YOU?
 
Long-term and short-term goals require different financial planning. Whether
you're seeking greater growth opportunity, looking for more income, or a
combination of both, Nationwide's Family of Funds, strategies, and services may
help.
 
While there is careful selection of securities and constant supervision of the
Funds, there can be no guarantee that a Fund's objective will be achieved.
 
CONSIDER YOUR TIME FRAME
 
For long-term goals, you have the luxury of time on your side. With goals five
or more years away -- where growth of your investments is the highest
priority -- you may want to consider Nationwide's Stock Funds. These funds
provide greater long-term return potential through portfolios of common stocks
with a higher degree of risk.
 
   
If you're seeking greater income today or have intermediate to long-term
goals -- you may want to consider Nationwide's Bond Funds. These funds invest in
high-quality and investment grade bonds, providing monthly income and normally
provide greater price stability than stock funds. Plus, it is also possible to
have capital appreciation in these funds.
    
 
For short-term goals such as saving for next year's needs, an emergency reserve,
or as a temporary "parking place" for your money -- the Money Market Fund may be
most appropriate for you. This fund provides investors with greater stability of
principal while providing current monthly income.
 
Most investors have a combination of long and short-term goals. By investing in
several, or all, of the Family of Funds, you'll have the opportunity to satisfy
your many investment needs.
 
ASSESS YOUR TOLERANCE FOR RISK
 
   
Where you choose to invest depends as much on your tolerance for risk as on your
desire for reward. Opportunity and risk go hand-in-hand. Generally the greater
the potential long-term opportunity, the greater the potential risk.
    
 
   
The most common risk people associate with investing is short-term market
risk -- the day-to-day fluctuation in an investment's value. Nationwide's
portfolio managers seek to minimize this risk by investing primarily in quality
securities.
    
 
Investors looking for greater growth in our Stock Funds should be willing to
accept greater account value fluctuation. A wide range of factors -- corporate
earnings potential, interest rates, competition, and other economic
conditions -- can cause both downward and upward share price changes.
 
   
In the past, investors with a long-term time horizon and a tolerance for
fluctuation have typically been rewarded. Despite years when short-term returns
have not been satisfactory, over long-term holding periods, money has grown more
in common stocks than in fixed income securities.
    
 
The Bond Funds generally provide investors with greater price stability than
stock funds. More predictable investments may make an investor more comfortable,
but historically the total return in bond funds has been less than in stock
funds. Prevailing interest rates, more than any other factor, contribute to
price fluctuation in bond funds, and long-term bonds are generally affected more
than shorter-term bonds. A discussion of the relationship of interest rates and
bond prices is found on page 26.
 
Investors who would prefer not to have their investment principal fluctuate
should consider the Money Market Fund. While it provides the greatest price
stability of these investments over the long term it has less long-term return
potential.

One of the biggest risks investors may face is being too conservative, thereby
not earning enough return on their investments to achieve their future needs.
Another big risk to consider is the eroding value of the dollar, known as
inflation. The amount of money needed to satisfy a goal (after taking inflation
into consideration) may dictate investment in a fund with a potential for
greater returns. Although common stocks are generally the most volatile over
short periods of time, historically they have provided double-digit returns and
exceeded inflation over long periods.
 
Procrastination is yet another risk investors must consider. Delay, and you take
the chance that there may not be enough time to attain your objective. Start
early and invest regularly in funds with growth opportunities, and you stand a
better chance to reach your goals.
 
For more information concerning the risk factors of the Funds, see "Investment
Techniques, Considerations and Risk Factors."
 
CONSIDER YOUR TAX BRACKET
 
For investors seeking to shelter their investment income from federal taxes, the
Tax-Free Income Fund may be an appropriate investment. The tax-equivalent yield
of this Fund can be especially appealing for investors in the 28% or higher tax
brackets. To determine if a tax-free investment may be right for you, see page
27.

THE MID CAP GROWTH FUND
INVESTMENT OBJECTIVE & POLICY: Seeks long-term capital appreciation. The Fund
invests primarily in a diversified portfolio of equity securities of mid cap
companies.
    
 
- - LONG-TERM GROWTH WITH CAPITAL APPRECIATION.
 
- - EQUITY PORTFOLIO -- GENERALLY MID CAP COMPANIES.
 
RISK PROFILE: The illustration below shows a continuum of risk. The triangle

</TABLE>
 
PORTFOLIO MANAGEMENT: Major emphasis in the selection of securities is placed on
companies which have capable management, and are in fields where social and
economic trends, technological developments, and new processes or products
indicate a potential for greater-than-average growth.
   
    The Fund will invest at least 65% of its total assets in equity securities
of mid cap companies. The fund defines mid cap companies as those with market
capitalization or sales in the range between $300 million and $8 billion, but
will generally focus on companies between $300 million and $5 billion. The
equity securities in which the Fund will invest are generally common stock or
securities convertible into common stocks ("convertible securities").
    

    Investments are made in different types of equity securities among many
companies and industries which provide diversification to help minimize risk.
 
   
PORTFOLIO MANAGER: John M. Schaffner, MBA, CFA -- is the portfolio manager for

economic growth of the companies it invests in, plus improvement in the
valuation of the stock. Major emphasis in the selection of securities is placed
on companies which have capable management, and are in fields where social and
economic trends, technological developments, and new processes or products
indicate a potential for greater-than-average growth.
    
   
    The Fund will invest at least 65% of its total assets in equity securities
of companies of all sizes, generally common stock and convertible securities.
    
   
    Investments are made in different types of equity securities among many
companies and industries which provide diversification to help minimize risk.

ADDITIONAL INFORMATION CONCERNING THE STOCK FUNDS
   
Equity securities include common stock, preferred stock, convertible securities
and warrants and the Funds may invest in both domestic and foreign issues. The
Fund may invest in foreign securities directly or through depository receipts.
In addition to investing in equity securities, the Stock Funds may invest in
index futures, options and other derivatives, and securities which are not
readily marketable or are restricted as to disposition. They may also invest in
U.S. government securities, short-term fixed income securities and money market
obligations ("Money Market Obligations") and shares of other investment
companies. The Stock Funds may also enter into repurchase agreements, and may
purchase when-issued securities.
    
   
    For temporary or emergency purposes as determined by Nationwide Advisory
Services, Inc. ("NAS"), each such Fund may invest up to 100% of its total assets
in cash, and/or money market obligations.
    
    See "Investment Techniques, Considerations and Risk Factors" below and
"Additional Information on Portfolio Instruments and Investment Policies" in the
Statement of Additional Information for further information.
 
THE BOND FUND
 
   
INVESTMENT OBJECTIVE & POLICY: Seeks a high level of income, consistent with
capital preservation. The Fund invests primarily in fixed-income securities
currently focusing on corporate debt investments and U.S. Government
mortgage-backed securities. Under normal market conditions, the average maturity
of the Fund will be intermediate, which is defined by the Fund as being between
6 and 10 years.
    
 
- - MONTHLY INCOME FROM A PORTFOLIO OF INVESTMENT GRADE CORPORATE AND GOVERNMENT
  OBLIGATIONS.
 
- - INTERMEDIATE MATURITIES -- YIELDS ARE USUALLY HIGHER THAN SHORT-TERM FUNDS,
  BUT WITH LOWER YIELDS AND VOLATILITY THAN LONG-TERM FUNDS.

PORTFOLIO MANAGEMENT: Major emphasis is placed on a diversified portfolio of
investment grade taxable debt securities including corporate debt securities
rated within the four highest credit categories by Standard & Poor's Corporation
("Standard & Poor's") (AAA, AA, A or BBB) or Moody's ("Moody's") (Aaa, Aa, A or
Baa), U.S. and Canadian Government obligations, mortgage-backed securities, and
the highest investment grade commercial paper rated by Moody's Investors
Service, Inc. (Prime-1 or Prime-2) or by Standard & Poor's (A-1 or A-2). The
Fund may invest in unrated securities if NAS determines them to be of comparable
quality. The Fund may also enter into repurchase agreements, purchase restricted
or illiquid securities which are not readily marketable or are restricted as to
disposition, and engage in securities lending transactions. The Fund also
purchases securities on a when-issued or delayed delivery.
    
   
    The Fund may invest in securities rated BBB by Standard & Poor's or Baa by
Moody's, commonly referred to as medium-grade securities which are considered by
Standard and Poor's and Moody's to have some speculative characteristics. While
interest payments and principal security appear adequate at the present time,
such securities lack certain protective elements or may be characteristically
unreliable over any great period of time.
    
    Should subsequent events cause the rating of BBB securities to fall below
this rating, NAS will consider such an event in determining whether the Fund
should continue to hold that security. In no event, however, would the Fund be
required to liquidate any portfolio security where the Fund would suffer a loss
on the sale of such security.
   
    In addition, for temporary or emergency purposes, the Fund may invest up to
100% of its total assets in cash and/or money market obligations.

PORTFOLIO MANAGEMENT: Major emphasis is placed on a diversified portfolio of
municipal obligations rated within the three highest credit categories
(investment grade) assigned by Moody's and Standard & Poor's or if not rated,
are of equivalent investment quality as determined by NAS.
    Such obligations include: (1) municipal securities backed by the full faith

highest credit categories Aaa, Aa, or A by Moody's and/or AAA, AA, or A by
Standard & Poor's; (3) state and municipal notes rated MIG-1, MIG-2, and MIG-3
by Moody's; and (4) other types of municipal securities such as commercial
paper, provided that such securities are rated at least Prime-2 by Moody's or
A-2 by Standard & Poor's.
   
    The Fund may also invest up to 10% of its net assets in securities rated BBB
by Standard & Poor's or Baa by Moody's or if not rated, are of equivalent
investment quality as determined by NAS. The municipal securities in which the
Fund may invest may include variable and floating rate securities. The Fund also
purchases securities on a when issued or delayed delivery basis.
    
    The Fund may, on a temporary basis or for defensive purposes, hold and
invest up to 20% of its assets in cash and in taxable money market obligations.
The Fund has, however, adopted an investment restriction which requires it to
invest at least 80% of its net assets in the types of securities listed in the
preceding paragraphs.

    The Fund may invest in mortgage-related securities issued by U.S. Government
agencies. These Securities include pass-through securities and collateralized
mortgage obligations (CMOs). Pass-through securities represent part ownership in
a pool of mortgage loans. These securities differ from typical bonds because
principal is repaid monthly over the term of the loan rather than returned in a
lump sum at maturity. CMOs are fully collateralized by a pool of mortgages on
which payments of principal and interest are dedicated to payment of principal
and interest on the various classes of the CMOs.
    
   
    The Fund may also invest in zero-coupon securities, that are direct
obligations of the U.S. government and its agencies and instrumentalities and in
money market obligations issued or guaranteed by the U.S. government, its

ADDITIONAL INFORMATION CONCERNING THE DURATION OF THE U.S. GOVERNMENT BOND
FUNDS: The Long-Term U.S. Government Bond Fund will attempt to limit its
exposure to interest rate risk by maintaining a duration which, on a weighted
average basis and under normal market conditions, will generally be greater than
six years, and the Intermediate U.S. Government Bond Fund will attempt to limit
its exposure by maintaining an average duration between three and a half and six
years. Duration is a measure of the average life of a fixed-income security that
was developed as a more precise alternative to the concepts of "term to
maturity" or "average dollar weighted maturity" as measures of "volatility" or
"risk" associated with changes in interest rates. Duration incorporates a
security's yield, coupon interest payments, final maturity and call features
into one measure.

    Most debt obligations provide interest ("coupon") payments in addition to
final ("par") payment at maturity. Some obligations also have call provisions.
Depending on the relative magnitude of these payments and the nature of the call
provisions, the market values of debt obligations may respond differently to
changes in interest rates.

    Traditionally, a debt security's "term-to-maturity" has been used as a
measure of the sensitivity of the security's price to changes in interest rates
(which is the "interest rate risk" or "volatility" of the security). However,
"term-to-maturity" measures only the time until a debt security provides its
final payment, taking no account of the pattern of the security's payments prior
to maturity. Average dollar weighted maturity is
    
 
                                        9
<PAGE>   13
 
                           OBJECTIVES AND MANAGEMENT
 
   
calculated by averaging the terms to maturity of each debt
security held with each maturity "weighted" according to the percentage of
assets that it represents. Duration is a measure of the expected life of a debt
security on a present value basis and reflects both principal and interest
payments. Duration takes the length of the time intervals between the present
time and the time that the interest and principal payments are scheduled or, in
the case of a callable security, expected to be received, and weights them by
the present values of the cash to be received at each future point in time. For
any debt security with interest payments occurring prior to the payment of
principal, duration is ordinarily less than maturity. In general, all other
factors being the same, the lower the stated or coupon rate of interest of a
debt security, the longer the duration of the security; conversely, the higher
the stated or coupon rate of interest of a debt security, the shorter the
duration of the security.
    There are some situations where the standard duration calculation does not
properly reflect the interest rate exposure of a security. For example, floating
and variable rate securities often have final maturities of ten or more years;
however, their interest rate exposure corresponds to the frequency of the coupon
reset. Another example where the interest rate exposure is not properly captured
by duration is the case of mortgage pass-through securities. The stated final
maturity of such securities is generally 30 years, but current prepayment rates
are more critical in determining the securities' interest rate exposure. In
these and other similar situations, the Adviser will use more sophisticated
analytical techniques to project the economic life of a security and estimate
its interest rate exposure. Since the computation of duration is based on
predictions of future events rather than known factors, there can be no
assurance that the U.S. Government Funds will at all times achieve its targeted
portfolio duration.
    The change in market value of U.S. Government fixed-income securities is
largely a function of changes in the prevailing level of interest rates. When
interest rates are falling, a portfolio with a shorter duration generally will
not generate as high a level of total return as a portfolio with a longer
duration. When interest rates are flat, shorter duration portfolios generally
will not generate as high a level of total return as longer duration portfolios
(assuming that long-term interest rates are higher than short-term rates, which
is commonly the case. When interest rates are rising, a portfolio with a shorter
duration will generally outperform longer duration portfolios. With respect to
the composition of a fixed-income portfolio, the longer duration of the
portfolio, generally the greater the anticipated potential for total return,
with, however, greater attendant interest rate risk and price volatility than
for a portfolio with a shorter duration.
    While each U.S. Government Fund intends to maintain the average duration
described above under normal market conditions, there is no limit as the
maturity of any one security which a U.S. Government Fund may purchase.
    
 
THE MONEY MARKET FUND
 
INVESTMENT OBJECTIVE & POLICY: Seeks as high a level of current income as is

that the Fund will be able to maintain a stable net asset value of $1.00 per
share.

dollar denominated obligations of foreign governments including Canadian
government and provincial obligations; obligations of commercial banks and
savings associations which have assets over $500 million [and are FDIC members],
and the 50 largest foreign banks with U.S. branches; taxable or partly taxable
obligations issued by state, county or municipal governments; commercial paper
rated in one of the two highest rating categories by at least two Nationally
Recognized Statistical Rating Organizations (NRSROs); corporate obligations at
the time of purchase with the two highest rating categories assigned by the
NRSROs; and repurchase agreements collateralized by any of the above. In
addition, the Fund may invest in variable rate demand notes. See "Investment

             INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS
 
An investment in the Funds involves certain risks. As a general matter, an
investment in the Funds (except the Money Market Fund) involves the risk that
the net asset value of a Fund's shares will fluctuate in response to changes in
economic conditions, interest rates, and the market's perception of the
securities held by the Fund. In addition, an investment in the Stock Funds is
subject to stock market risk, which means that such an investment is subject to
the risk that stock prices in general will decline over short or extended
periods of time. An investment in the Bond Funds is subject to bond market risk,
i.e., the risk that the market price of bonds in general will fluctuate. Bond
prices fluctuate largely in response to changes in the level of interest rates.
When interest rates rise, bond prices generally fall; conversely, when interest
rates fall, bond prices generally rise. Although the fluctuation in the price of
bonds is normally less than that of common stocks, in the past there have been
extended periods of cyclical increases in interest rates, causing significant
declines in the price of bonds in general.
    An investment in the Funds is subject to other risks as well, depending upon
the particular investment techniques employed by a Fund and the types of
securities in which a Fund invests. These risks are described below.
 
   
SPECIAL SITUATION COMPANIES -- The Mid Cap Growth Fund may invest in securities
of issuers in special situations. These securities also may be more volatile,
since the market value of these securities may decline in value if the
anticipated benefits do not materialize. Companies in "special situations"
include, but are not limited to, companies involved in an acquisition or
consolidation; reorganization; recapitalization; merger, liquidation or
distribution of cash, securities or other assets; a tender or exchange offer, a
breakup or workout of a holding company; litigation which, if resolved
favorably, would improve the value of the companies' securities; or change in
corporate control.
    
 
   
Although investing in securities of issuers in "special situations" offers
potential for above-average returns if the companies are successful, the risk
exists that the companies will not succeed, and the prices of the companies'
shares could significantly decline in value. Therefore, an investment in the Mid
Cap Growth Fund may involve a greater degree of risk than an investment in other
mutual funds that seek long-term growth of capital by investing in better-known,
larger companies.
    
 
WARRANTS -- Each Stock Fund may invest in warrants. A warrant is an instrument
which gives the holder the right to subscribe to a specified amount of the
issuer's securities at a set price for a specified period of time or on a
specified date. Warrants do not carry the right to dividends or voting rights
with respect to their underlying securities and do not represent any rights in
assets of the issuer. An investment in warrants may be considered speculative.
In addition, the value of a warrant does not necessarily change with the value
of the underlying securities, and a warrant ceases to have value if it is not
exercised prior to its expiration date.
 
CONVERTIBLE SECURITIES -- The Stock Funds may invest in convertible securities,
which are bonds, debentures, notes, preferred stocks or other securities that
may be converted into or exchanged for a specified amount of common stock of the
same or a different issuer within a particular period of time at a specified
price or formula. Convertible securities have general characteristics similar to
both debt obligations and equity securities. Although to a lesser extent than
with debt obligations generally, the market value of convertible securities
tends to decline as interest rates increase and, conversely, tends to increase
as interest rates decline. In addition, because of the conversion feature, the
market value of convertible securities tends to vary with fluctuations in the
market value of the underlying common stock and therefore will react to
variations in the general market for equity securities. A unique feature of
convertible securities is that as the market price of the underlying common
stock declines, convertible securities tend to trade increasingly on a yield
basis and so may not experience market value declines to the same extent as the
underlying common stock. When the market price of the underlying common stock
increases, the prices of the convertible securities tend to rise as a reflection
of the value of the underlying common stock. While no securities investments are
without risk, investments in convertible securities generally entail less risk
than investments in common stock of the same issuer.
    As fixed-income securities, convertible securities are investments that
provide for a stable stream of income with generally higher yields than common
stocks. Of course, like all debt obligations, there can be no assurance of
current income because the issuers of the convertible securities may default on
their obligations. Convertible securities, however, generally offer lower
interest or dividend yields than non-convertible securities of similar quality
because of the potential for capital appreciation. A convertible security, in
addition to providing fixed income, offers the potential for capital
appreciation through the conversion feature, which enables the holder to benefit
from increases in the market price of the underlying common stock. There can be
no assurance of capital appreciation, however, because the market value of
securities will fluctuate.
    Convertible securities generally are subordinated to other similar but
non-convertible securities of the same issuer, although convertible bonds, as
corporate debt obligations, enjoy

seniority in right of payment to all equity securities, and
convertible preferred stock is senior to common stock of the same issuer.
Because of the subordination feature, however, convertible securities typically
are rated below investment grade or are not rated.
 
U.S. GOVERNMENT SECURITIES -- As discussed above, each of the Funds may invest
in securities which are issued or guaranteed by the U.S. government or its
agencies or instrumentalities. Securities issued by the U.S. government include
U.S. Treasury obligations, such as Treasury bills, notes, and bonds. Securities
issued by government agencies or instrumentalities include, but are not limited
to, obligations of the following:
 
- - the Federal Housing Administration, Farmers Home Administration, and the
  Government National Mortgage Association ("GNMA"), including GNMA pass-through
  certificates, whose securities are supported by the full faith and credit of
  the United States;
 
- - the Federal Home Loan Banks.
 
- - the Federal National Mortgage Association.
 
- - the Student Loan Marketing Association, Federal Home Loan Mortgage Corporation
  ("FHLMC"), and the International Bank for Reconstruction and Development.
 
    The U.S. Government and its agencies and instrumentalities do not guarantee
the market value of their securities; consequently, the value of such securities
will fluctuate.
 
   
MORTGAGE- AND ASSET-BACKED SECURITIES -- The Bond Funds (except Tax-Free Income
Fund) may purchase mortgage-backed securities. The Nationwide Bond Fund and the
Nationwide Money Market Fund may also invest in asset-backed securities.
Mortgage-backed securities represent direct or indirect participation in, or are
secured by and payable from, mortgage loans secured by real property, and
include single- and multi-class pass-through securities and CMOs. Such
securities may be issued or guaranteed by U.S. Government, and its agencies or
instrumentalities or in the case of the Nationwide Bond Fund only, by private
issuers, generally originators of or investors in mortgage loans, including
savings and loan associations, mortgage bankers, commercial banks, investment
banks, and special purpose entities (collectively, "private lenders"). Mortgage-
backed securities issued by private lenders may be supported by pools of
mortgage loans or other mortgage-backed securities that are guaranteed, directly
or indirectly, by the U.S. Government or one of its agencies or
instrumentalities, or they may be issued without any governmental guarantee of
the underlying mortgage assets but with some form of non-governmental credit
enhancement. The underlying mortgage assets may have fixed rates or adjustable
rates of interest. Mortgage-backed securities in which the Bond Funds may invest
include both fixed-rate and adjustable-rate mortgage-backed securities.
    
    The Nationwide Bond Fund may purchase mortgage-backed securities issued by
private issuers, and therefore, the purchase of such securities may entail
greater risk than mortgage-backed securities that are guaranteed by the U.S.
Government, its agencies or instrumentalities. Since privately-issued mortgage
certificates are not guaranteed by an entity having the credit status of GNMA or
FHLMC, such securities generally are structured with one or more types of credit
enhancement. Such credit support falls into two categories: (i) liquidity
protection; and (ii) protection against losses resulting from ultimate default
by an obligor on the underlying assets. Liquidity protection refers to the
provisions of advances, generally by the entity administering the pool of
assets, to ensure that the pass-through of payments due on the underlying pool
occurs in a timely fashion. Protection against losses resulting from ultimate
default enhances the likelihood of ultimate payment of the obligations on at
least a portion of the assets in the pool. Such protection may be provided
through guarantees, insurance policies or letters of credit obtained by the
issuer or sponsor from third parties, through various means of structuring the
transaction or through a combination of such approaches.
    Asset-backed securities have structural characteristics similar to
mortgage-backed securities. However, the underlying assets are not first-lien
mortgage loans or interests therein; rather they include assets such as motor
vehicle installment sales contracts, other installment loan contracts, home
equity loans, leases of various types of property and receivables from credit
card and other revolving credit arrangements. Payments or distributions of
principal and interest on asset-backed securities may be supported by
non-governmental credit enhancements similar to those utilized in connection
with mortgage-backed securities.
    The yield characteristics of mortgage-backed securities differ from those of
traditional debt obligations. Among the principal differences are that interest
and principal payments are made more frequently on mortgage- and asset-backed
securities, usually monthly, and that principal may be prepaid at any time
because the underlying mortgage loans or other assets generally may be prepaid
at any time. As a result, if a Fund purchases these securities at a premium, a
prepayment rate that is higher than expected will reduce yield, while a
prepayment rate that is lower than expected will have the opposite effect of
increasing the yield. Conversely, if a Fund purchases these securities at a
discount, a prepayment rate that is faster than expected will increase yield,
while a prepayment rate that is slower than expected will reduce yield.
Accelerated prepayments on securities purchased by the Fund at a premium also
impose a risk of loss of principal because the premium may not have been fully
amortized by the time the principal is prepaid in full.

             INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS
 
    Unlike fixed rate mortgage securities, adjustable rate mortgage securities
are collateralized by or represent interest in mortgage loans with variable
rates of interest. These variable rates of interest reset periodically to align
themselves with market rates. The Fund will not benefit from increases in
interest rates to the extent that interest rates rise to the point where they
cause the current coupon of the underlying adjustable rate mortgages to exceed
any maximum allowable annual or lifetime reset limits (or "cap rates") for a
particular mortgage. In this event, the value of the adjustable rate
mortgage-backed securities in the Fund would likely decrease. Also, the Fund's
net asset value could vary to the extent that current yields on adjustable rate
mortgage-backed securities are different than market yields during interim
periods between coupon reset dates or if the timing of changes to the index upon
which the rate for the underlying mortgage is based lags behind charges in
market rates. During periods of declining interest rates, income to the Fund
derived from adjustable rate mortgages which remain in a mortgage pool will
decrease in contrast to the income on fixed rate mortgages, which will remain
constant. Adjustable rate mortgages also have less potential for appreciation in
value as interest rates decline than do fixed rate investments.
    The ratings of mortgage securities for which third-party credit enhancement
provides liquidity protection or protection against losses from default are
generally dependent upon the continued creditworthiness of the provider of the
credit enhancement. The ratings of such securities could be subject to reduction
in the event of deterioration in the creditworthiness of the credit enhancement
provider even in cases where the delinquency loss experience on the underlying
pool of assets is better than expected. There can be no assurance that the
private issuers or credit enhancers of mortgage-backed securities can meet their
obligations under the relevant policies or other forms of credit enhancement.
    Examples of credit support arising out of the structure of the transaction
include "senior-subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal thereof
and interest thereon, with the result that defaults on the underlying assets are
borne first by the holders of the subordinated class), creation of "reserve
funds" (where cash or investments sometimes funded from a portion of the
payments on the underlying assets are held in reserve against future losses) and
"over-collateralization" (where the scheduled payments on, or the principal
amount of, the underlying assets exceed those required to make payment of the
securities and pay any servicing or other fees). The degree of credit support
provided for each issue is generally based on historical information with
respect to the level of credit risk associated with the underlying assets.
Delinquency or loss in excess of that which is anticipated could adversely
affect the return on an investment in such security.
 
COLLATERALIZED MORTGAGE OBLIGATIONS -- The Bond Funds may also acquire CMOs and
stripped mortgage-backed securities. CMOs are debt obligations collateralized by
mortgage loans or mortgage pass-through securities. Typically, CMOs are
collateralized by GNMA, FNMA or FHLMC certificates, but also may be
collateralized by whole loans or private mortgage pass-through securities (such
collateral collectively referred to as "Mortgage Assets"). Payments of principal
or interest on the Mortgage Assets, and any reinvestment income thereon, priced
the funds to pay debt service on the CMOs. CMOs may be issued by agencies or
instrumentalities of the U.S. Government or by private originators of, or
investors in, mortgage loans.
 
   
INTEREST ONLY AND PRINCIPAL ONLY SECURITIES -- Stripped mortgage-backed
securities are securities representing interest in a pool of mortgages the cash
flow from which has been separated into interest and principal components. "IOs"
(interest only securities) receive the interest portion of the cash flow while
"POs" (principal only securities) receive the principal portion. Stripped
mortgage-backed securities may be issued by U.S. Government agencies or by
private issuers, such as mortgage banks, commercial banks, investment banks,
savings and loan associations and special purpose subsidiaries of the foregoing.
As interest rates rise and fall, the value of IOs tends to move in the same
direction as interest rates. The value of other mortgage-backed securities
described herein, like other debt instruments, will tend to move in the opposite
direction compared to interest rates. POs perform best when prepayments on the
underlying mortgages rise since this increases the rate at which the investment
is returned and the yield to maturity on the PO. When payments on mortgages
underlying a PO are slow, the life of the PO is lengthened and the yield to
maturity is reduced.
 
    Each Bond Fund may purchase stripped mortgage-backed securities for hedging
purposes to protect that Fund against interest rate fluctuations. For example,
since an IO will tend to increase in value as interest rates rise, it may be
utilized to hedge against a decrease in value of other fixed-income securities
in a rising interest rate environment. If the Fund purchases a mortgage-related
security at a premium, all or part of the premium 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. Moreover,
with respect to stripped mortgage-backed securities, if the underlying mortgage
securities experience greater than anticipated prepayments of principal, the
Fund may fail to recoup fully its initial investment in these securities even if
the securities are rated in the highest rating category by an NRSRO. Stripped

<PAGE>   17
 
             INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS
 
   
mortgage-backed securities may exhibit greater price volatility than ordinary
debt securities because of the manner in which their principal and interest are
returned to investors. The market value of the class consisting entirely of
principal payments can be extremely volatile in response to changes in interest
rates. The yields on stripped mortgage-backed securities that receive all or
most of the interest are generally higher than prevailing market yields on other
mortgage-backed obligations because their cash flow patterns are also volatile
and there is a greater risk that the initial investment will not be fully
recouped. No more than 10% of a Bond Fund's total assets will be invested in IOs
and in POs.
 
MUNICIPAL SECURITIES -- The two principal classifications of Municipal
Securities which may be held by the Tax-Free Income Fund are "general
obligation" securities and "revenue" securities. General obligation securities
are secured by the issuer's pledge of its full faith, credit and taxing power
for the payment of principal and interest. Revenue securities are payable only
from the revenues derived from a particular facility or class of facilities or,
in some cases, from proceeds of a special excise tax or other specific revenue
source such as the user of the facility being financed. Private activity bonds
held by the Tax-Free Income Fund are in most cases revenue securities and are
not payable from the unrestricted revenues of the issuer. Consequently, the
credit quality of private activity bonds is usually directly related to the
credit standing of the corporate user of the facility involved.
    The Tax-Free Income Fund may also invest in "moral obligation" securities,
which are normally issued by special purpose public authorities. If the issuer
of moral obligation securities is unable to meet its debt service obligations
from current revenues, it may draw on a reserve fund, the restoration of which
is a moral commitment but not a legal obligation of the state or municipality
which created the issuer.
    
 
REPURCHASE AGREEMENTS -- Each of the Funds may engage in repurchase agreement
transactions as long as the underlying securities are of the type that the Fund
would be permitted to purchase directly. Under the terms of a typical repurchase
agreement, the Fund would acquire an underlying security for a relatively short
period (usually not more than one week) subject to an obligation of the seller
to repurchase, and the Fund to resell, the obligation at an agreed upon price
and time, thereby determining the yield during the Fund's holding period. The
Fund will enter into repurchase agreements with member banks of the Federal
Reserve System or certain non-bank dealers. Under each repurchase agreement the
selling institution will be required to maintain the value of the securities
subject to the repurchase agreement at not less than their repurchase price
(including interest). Repurchase agreements could involve certain risks in the
event of default or insolvency of the other party, including possible delays or
restrictions upon a Fund's ability to dispose of the underlying securities. NAS,
acting under the supervision of the Board of Trustees, reviews the
creditworthiness of those banks and non-bank dealers with which the Fund enters
into repurchase agreements to evaluate these risks. For additional information,
see "Repurchase Agreements" in the Statement of Additional Information.
 
INVESTMENT COMPANIES -- As permitted by the 1940 Act, each Fund may invest up to
10% of its total assets, calculated at the time of investment, in the securities
of other investment companies. No more than 5% of a Fund's total assets may be
invested in the securities of any one investment company nor may it acquire more
than 3% of the voting securities of any other investment company. Each Fund will
indirectly bear its proportionate share of any management fees paid by an
investment company in which it invests in addition to the advisory fee paid by
the Fund.
 
WHEN-ISSUED SECURITIES -- Each of the Funds may invest without limitation in
securities purchased on a when-issued or delayed delivery basis. Although the
payment and interest terms of these securities are established at the time the
Fund enters into the commitment, these securities may be delivered and paid for
at a future date, generally within 45 days; for mortgage-backed securities, the
delivery date may extend to as long as 120 days. Purchasing when-issued
securities allows a Fund to lock in a fixed price or yield on a security it
intends to purchase. However, when the Fund purchases a when-issued security, it
immediately assumes the risk of ownership, including the risk of price
fluctuation until the settlement date.
    The greater a Fund's outstanding commitments for these securities, the
greater the exposure to potential fluctuations in the net asset value of a Fund.
Purchasing when-issued securities may involve the additional risk that the yield
available in the market when the delivery occurs may be higher or the market
price lower than that obtained at the time of commitment. Although the Fund may
be able to sell these securities prior to the delivery date, it will purchase
when-issued securities for the purpose of actually acquiring the securities,
unless after entering into the commitment a sale appears desirable for
investment reasons. The Fund will set aside liquid assets in a segregated
account to secure its outstanding commitments for when-issued securities.
 
FLOATING AND VARIABLE RATE OBLIGATIONS -- The Bond Funds and the Money Market
Fund may invest in floating and variable rate obligations. Floating or variable
rate obligations bear interest at rates that are not fixed, but vary with
changes in specified market
 
                                       14
<PAGE>   18
 
             INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS
 
rates or indices, such as the prime rate, and at specified intervals. Floating
rate obligations vary with changes to an underlying index while variable rate
obligations change at preset fixed times. Certain of the floating or variable
rate obligations that may be purchased by these Funds may carry a demand feature
that would permit the holder to tender them back to the issuer at par value
prior to maturity. Such obligations include variable rate master demand notes,
which are unsecured instruments issued pursuant to an agreement between the
issuer and the holder that permit the indebtedness thereunder to vary and
provide for periodic adjustments in the interest rate. The Bond Funds and the
Money Market Fund will limit their purchases of floating and variable rate
obligations to those of the same quality as they otherwise are allowed to
purchase. NAS will monitor on an ongoing basis the ability of an issuer of a
demand instrument to pay principal and interest on demand.
    Although there may be no active secondary market with respect to a
particular variable or floating rate obligation purchased by a Fund, the Fund
may attempt to resell the obligation at any time to a third party. The absence
of an active secondary market, however, could make it difficult for a Fund to
dispose of a variable or floating rate obligation in the event the issuer of the
obligation defaulted on its payment obligations and the Fund could, as a result
or for other reasons, suffer a loss to the extent of the default. Variable or
floating rate obligations may be secured by bank letters of credit.
    In the event the interest rate of a variable or floating rate obligation is
established by reference to an index or an interest rate that may from time to
time lag behind other market interest rates, there is the risk that the market
value of such obligation, on readjustment of its interest rate, will not
approximate its par value.
    Variable and floating rate obligations for which no readily available market
exists and which are not subject to a demand feature that will permit the Fund
to receive payment of the principal within seven days after demand by that Fund,
will be considered illiquid and therefore, together with other illiquid
securities held by such Fund, will not exceed 15% of such Fund's net assets.
    For a further discussion of floating and variable rate obligations, see
"Additional Information on Portfolio Instruments and Investment
Policies -- Floating and Variable Rate Instruments" in the Statement of
Additional Information.
 
ZERO COUPON SECURITIES -- The Bond Funds may invest in zero coupon securities.
Zero coupon securities are debt securities that pay no cash income but are sold
at substantial discounts from their value at maturity. When a zero coupon
security is held to maturity, its entire return, which consists of the
amortization of discount, comes from the difference between its purchase price
and its maturity value. This difference is known at the time of purchase, so
that investors holding zero coupon securities until maturity know at the time of
their investment what the expected return on their investment will be. Certain
zero coupon securities also are sold at substantial discounts from their
maturity value and provide for the commencement of regular interest payments at
a deferred date. Zero coupon securities may have conversion features.
    Zero coupon securities tend to be subject to greater price fluctuations in
response to changes in interest rates than are ordinary interest-paying debt
securities with similar maturities. The value of zero coupon securities
appreciates more during periods of declining interest rates and depreciates more
during periods of rising interest rates than ordinary interest-paying debt
securities with similar maturities. Zero coupon securities may be issued by a
wide variety of corporate and governmental issuers. Although these instruments
are generally not traded on a national securities exchange, they are widely
traded by brokers and dealers and, to such extent, will not be considered
illiquid for the purposes of the Fund's limitation on investments in illiquid
securities.
    Current federal income tax law requires the holder of a zero coupon security
to accrue income with respect to these securities prior to the receipt of cash
payments. Accordingly, to avoid liability for federal income and excise taxes,
the Bond Funds may be required to distribute income accrued with respect to
these securities and may have to dispose of portfolio securities under
disadvantageous circumstances in order to generate cash to satisfy these
distribution requirements.
 
MONEY MARKET OBLIGATIONS -- Each of the Funds may invest its assets in
high-quality short-term money market obligations.
    Money Market Obligations in which the Funds may invest include: 1) U.S.
Government Securities (as described above) with remaining maturities of one year
or less; 2) commercial paper rated in one of the two highest ratings categories
of any NRSRO (e.g., Moody's or Standard & Poor's); 3) short-term bank
obligations that are rated in one of the two highest categories by any NRSRO,
with respect to obligations maturing in one year or less; 4) repurchase
agreements relating to debt obligations which a Fund could purchase directly; 5)
unrated debt obligations with remaining maturities of one year or less which are
determined by NAS to be of comparable quality; or 6) money market mutual funds.
 
   
CANADIAN AND PROVINCIAL OBLIGATIONS -- The Money Market Fund may invest in
Canadian and Provincial obligations. They are unsecured, discounted Bills and
notes are issued in U.S. currency. Obligations have a final maturity of 270 days
or less from date of issue and are exempt from registration under sec-
    
 
                                       15

tion 3(a)(3) of the Securities Act of 1933, as amended. Canada Bills constitute
direct, unconditional obligations of Her Majesty in right of Canada and are a
direct charge on, and payable out of the Consolidated Revenue Fund of Canada.
Export Development Company and Canadian Wheat Board are crown corporations and
agents of her majesty in right of Canada. Provincial obligations have the full
faith and credit of the provincial governments.
    
 
MEDIUM QUALITY OBLIGATIONS -- The Nationwide Bond and Tax-Free Income Funds may
invest in medium-quality obligations. Medium-quality obligations are obligations
rated in the fourth highest rating category by any NRSRO. Medium-quality
securities, although considered investment-grade, may have some speculative
characteristics and may be subject to greater fluctuations in value than
higher-rated securities. In addition, the issuers of medium quality securities
may be more vulnerable to adverse economic conditions or changing circumstances
than that of higher-rated issuers.
    All ratings are determined at the time of investment. Any subsequent rating
downgrade of a debt obligation will be monitored by NAS to consider what action,
if any, a Fund should take consistent with its investment objective; such event
will not automatically require the sale of the downgraded securities.
 
LENDING PORTFOLIO SECURITIES -- From time to time, the Funds may lend their
portfolio securities to brokers, dealers and other financial institutions who
need to borrow securities to complete certain transactions. In connection with
such loans, a Fund will receive collateral consisting of cash, U.S. Government
securities or irrevocable letters of credit. Such collateral will be maintained
at all times in an amount equal to at least 100% of the current market value of
the loaned securities. A Fund can increase its income through the investment of
such collateral and continues to be entitled to payments in amounts equal to the
interest, dividends or other distributions payable on the loaned security and
receives interest on the amount of the loan. Such loans will be terminable at
any time upon specified notice. The Fund might experience risk of loss if the
institution with which it has engaged in a portfolio loan transaction breaches
its agreement with the Fund.
 
BORROWING MONEY -- The Funds may borrow money from banks up to 33 1/3% of their
total assets (including the amount borrowed). However, the Funds currently
intend to borrow money only for temporary or emergency purposes (but not for
leverage or to purchase investments) up to 5% of the value of a Fund's total
assets (including the amount borrowed) valued at the time the borrowing is made.
 
DERIVATIVE INSTRUMENTS -- NAS may use a variety of derivative instruments,
including options, futures contracts ("futures"), options on futures, stock
index options and forward currency contracts to hedge a Stock Fund's portfolio
or for risk management. Derivatives are financial instruments whose value and
performance are based on the value and performance of another security,
financial instrument or index.
 
PORTFOLIO TURNOVER
The Funds will attempt to purchase securities with the intent of holding them
for investment but may purchase and sell portfolio securities whenever NAS
believes it to be in the best interests of a Fund. The Funds will not consider
portfolio turnover rate a limiting factor in making investment decisions
consistent with their investment objective and policies.
   
    The annual portfolio turnover rate for each of the Funds (except the Money
Market Fund) is not expected to exceed 150% of such Fund's portfolio. For
regulatory purposes, the Money Market Fund is expected to have a 0% portfolio
turnover rate. Higher turnover rates will generally result in higher transaction
costs to the Fund, as well as higher brokerage expenses and higher levels of
capital gains. The portfolio turnover rates of each Fund may vary greatly from
year to year and within a particular year.

HOW TO PURCHASE SHARES
 
YOU MAY INVEST IN THREE CONVENIENT WAYS:
 
BY MAIL -- Complete the application and mail with your check or other negotiable
bank draft payable to: NATIONWIDE ADVISORY SERVICES, INC., THREE NATIONWIDE
PLAZA, P.O. BOX 1492, COLUMBUS, OHIO 43216-1492. Purchases must be made in U.S.
dollars only. The share price you receive will be determined as of the close of
business on the day the properly completed application is received by NAS in
Columbus, Ohio. Checks or drafts drawn on non-U.S. banks are not accepted. NAS
reserves the right to refuse certain third-party checks.
 
BY WIRE -- To avoid mail delays on initial and subsequent investments, you can
request that your bank transmit funds (Federal Funds) by wire to the Fund's
custodian bank. In order to use this method, you must call NAS by 11 A.M.
Eastern Time, and the wire must be received by the custodian bank by 2 P.M.
Eastern Time. The bank that wires your money may charge you a fee for this
service. IF YOU CHOOSE THIS METHOD TO OPEN YOUR ACCOUNT, YOU MUST CALL OUR
TOLL-FREE NUMBER BEFORE YOU WIRE YOUR INVESTMENT. If this is an initial
investment, you must then complete and mail the application.
 
BY TELEPHONE (NAS NOW) -- By calling 1-800-637-0012, 24 hours a day, seven days
a week you will be connected to our new automated voice-response system, NAS
NOW. It gives you quick, easy access to mutual fund information. Select from a
menu of choices to conduct transactions and hear fund price information, mailing
and wiring instructions as well as other mutual fund information.
 
IN ORDER TO USE NAS NOW TO MAKE A PURCHASE YOU MUST COMPLETE THE APPROPRIATE
SECTION ON THE APPLICATION.

The net asset value per share for each Fund is determined as of the close of
regular trading on the New York Stock Exchange (usually 4 P.M. Eastern Time),
each day that the exchange is open and on such other days as the Board of
Trustees determines and on days in which there is sufficient trading in
portfolio securities to materially affect the net asset value of that Fund.

    The Funds will not compute net asset value on customary business holidays,
including Christmas, New Year's Day, Martin Luther King, Jr. Day, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day and Thanksgiving.

    The net asset value per share is computed by adding the value of all
securities and other assets in the portfolio, deducting any liabilities and
dividing by the number of shares outstanding.
 
THE PURCHASE PRICES OF THE FUNDS ARE DETERMINED AS FOLLOWS:
   
PURCHASE PRICE OF CLASS D SHARES
    
(EXCEPT MONEY MARKET FUND)

   
In determining net asset value, portfolio securities listed on national
exchanges are valued at the last sale price on the principal exchange, or if
there is no sale on that day, or if the securities are traded only in the
over-the-counter market, at the quoted bid prices, all obtained from an
independent pricing organization. Securities for which market quotations are not
available are valued at fair value in accordance with procedures adopted by the
Board of Trustees. Expenses and fees are accrued daily. Shares of the non-money
market funds are purchased at the offering price. The offering price is
determined by adding the sales charge (based as a percentage of the offering
price) to the net asset value per share. THE SALES CHARGE IS DETERMINED
ACCORDING TO THE "SALES CHARGE SCHEDULE AND AVAILABLE DISCOUNTS" SECTION BELOW.
    
 
   
SALES CHARGE SCHEDULE AND AVAILABLE DISCOUNTS FOR CLASS D SHARES

accumulated value of all shares held in any of the Nationwide Investing
Foundation III Funds (except Nationwide Money Market Fund) including shares
acquired by reinvestment of dividends and capital gains distributions.

FAMILY MEMBER DISCOUNT

Market Fund) of members of the registrant's family may be included, provided

                         NATIONWIDE(R) FAMILY OF FUNDS
 
accordance with Rule 2a-7 of the Investment Company Act of 1940 as amended.
 
NO SALES CHARGE ON MONEY MARKET -- You pay no sales charge when you invest or
redeem in the Money Market Fund.
 
HOW TO SELL (REDEEM) SHARES
 
You can sell (redeem) all, or any part of, your shares of any Fund at any time.
Shares are redeemed at net asset value next computed after receipt of the
properly completed request by NAS, at its offices in Columbus, Ohio.
    Requests for redemptions may be in writing or by telephone (if authorized).
Payment for shares redeemed is made within 3 business days of receipt. The value
of shares redeemed depends upon the market value of the investments of each Fund
at the time of redemption and may be more or less than the shareholders' cost.
    You cannot redeem investments which have been on deposit for a period of
less than 12 days. This is to assure that your check has cleared. To avoid this
possible 12-day delay, you may make your investment by wire (see "How To
Purchase Shares by Wire," page 19). You will receive a confirmation each time a
liquidation of shares is requested. Redemptions may be suspended or the date of
payment postponed when the New York Stock Exchange is closed (other than
customary weekend and holiday closings listed in the "How To Purchase Shares"
section, page 19), or if trading is restricted or if any emergency exists.

   to request these forms, please call our customer service line at
   1-800-848-0920.
 
   You must call our toll-free number by 4:00 p.m. Eastern Time to receive that
   day's closing share price.
 
   The Funds will employ reasonable procedures to confirm that instructions
   communicated by telephone are genuine. The Funds will not be liable for any
   loss, injury, damage, or expense as a result of acting upon instructions
   communicated by telephone reasonably believed to be genuine, and the Funds
   will be held harmless from any loss, claims or liability arising from its
   compliance with such instructions. These options are subject to the terms and
   conditions set forth in this prospectus and all telephone transaction calls
   may be tape recorded. The Funds reserve the right to revoke this privilege at
   any time and request the redemption in writing, signed by all shareholders.
 
   BY BANK WIRE -- Your funds will be wired to your bank on the next business
   day after your redemption order has been processed. A $5 fee will be deducted
   from the proceeds for this service. Your financial institution may also
   charge you a fee for receipt of the wire. (If elected, this authorization
   will remain in effect until written notice of its termination is received by
   NAS.)
 
   BY ACH -- Your funds will be sent via ACH to your bank account on the second
   business day after your redemption order has been processed. There is no fee
   to receive your funds via ACH. (If elected, this authorization will remain in
   effect until written notice of its termination is received by NAS.) Funds
   sent through the automated clearing house should reach your bank in two
   business days.
 
   BY WESTERN UNION -- With Western Union's Quick Cash(R) service, you can
   receive your redemptions the next day across the United States or throughout
   the world. If you have elected, you can phone in your request to receive
   funds, next business day, at 24,000 locations - including major supermarkets
   and mail-box type outlets - many open 24 hours a day, seven days a week. The
   fee for the Western Union service is $9.50 per $10,000.00. Funds being sent

                         NATIONWIDE(R) FAMILY OF FUNDS
 
   outside of The United States may be subject to a higher fee. This fee is
   deducted from your account.
 
BY MAIL OR FAX (NO MINIMUM) -- Write or fax to Nationwide Advisory Services,
Inc., Three Nationwide Plaza, P.O. Box 1492, Columbus, Ohio 43216-1492 or FAX
(614) 249-8705. Please be sure that your letter or facsimile is signed exactly
as your account is registered and that your account number and the Fund from
which you wish to make the withdrawal are included. For example, if your account
is registered John Doe and Mary Doe, 'Joint Tenants With Right of Survivorship,'
then both John and Mary must sign the redemption request. For an IRA redemption,
you must include date of birth. Also, you must indicate whether or not you wish
Federal income tax (not less than 10%) to be withheld from the distribution. The
distribution will be processed effective the date the signed letter or fax is
received. Fax requests received after 4 P.M. Eastern time will be processed as
of the next business day. NAS reserves the right to require the original
document if you use the fax method.
 
BY MONEY MARKET CHECK WRITING -- Money Market shareholders receive free check
writing privileges. If you wish to withdraw your money this way, please complete
the appropriate section of the application. You pay no fee for this service, but
the Fund reserves the right to charge for it or to terminate this service.
    IF YOU HAVE MONEY MARKET CHECK WRITING PRIVILEGES, YOU SHOULD NOT ATTEMPT TO
REDEEM YOUR ENTIRE ACCOUNT BY WRITING A CHECK. This is because dividends are
accrued daily which will not be credited to your account until the end of the
month. This could result in a small remaining balance, which would be subject to
the $2 per month fee on Money Market accounts below minimum requirements.
 
ALTERNATE METHODS -- In the event of significant market activity, it may be
difficult to reach Nationwide Advisory Services, Inc. by telephone. If so, an
investor may choose to use alternate methods to contact NAS such as sending
instructions by a special delivery service, or by facsimile (FAX) machine
(614-249-8705). If you use the FAX method, NAS reserves the right to require the
original document.
 
ACCOUNTS FALLING BELOW MINIMUM INVESTMENT REQUIREMENTS
Because of the high cost of maintaining small accounts, NAS MAY CLOSE ANY
ACCOUNT WHICH, AS A RESULT OF REDEMPTIONS, HAS A VALUE OF LESS THAN $250
(EXCLUDING AUTOMATIC ASSET ACCUMULATION(SM) accounts). However, you will be
notified if your account value is less than the required minimum, and you will
be allowed 90 days to make additional investments before the account is
liquidated.
    IN THE CASE OF A MONEY MARKET FUND ACCOUNT BELOW $250 ON AVERAGE FOR ANY
MONTH, A $2 MONTHLY FEE WILL BE ASSESSED. The fee is deposited into the Fund to
offset the expenses of carrying these small accounts. Shares are redeemed in the
first week of the following month to cover the fee.
 
SIGNATURE GUARANTEE
NAS reserves the right to require that your signature be guaranteed by an
authorized agent of an "eligible guarantor institution," which include, but are
not limited to, certain banks, credit unions, savings associations, and member
firms of national security exchanges. A signature guarantee is designed to
protect the shareholder by helping to prevent an unauthorized person from
redeeming shares and obtaining the proceeds. A notary public is not an
acceptable guarantor. In certain special cases (such as corporate or fiduciary
registrations), additional legal documents may be required to ensure proper
authorizations.
 
INVESTOR STRATEGIES
 
1 MONEY MARKET PLUS GROWTH(SM) -- This strategy provides the security of
principal that the Money Market Fund offers plus the opportunity for greater
long-term capital appreciation through reinvestment of dividends into one of the
Stock Funds.
    An initial investment of $5,000 or more is made in the Money Market, and
monthly dividends are then automatically invested into one or more of the Stock
Funds chosen at such Stock Fund's current offering price. Money Market Plus
Growth(SM) gives investors stability of principal through the Money Market's
stable share price, and its portfolio of high quality, short-term money market
investments. And the Money Market Fund offers instant liquidity through
unlimited free checking ($500 minimum), telephone redemption, or NAS NOW. NOTE:
Money Market Fund dividends reinvested into one of the Stock Funds are subject
to applicable sales charges.
 
2 MONEY MARKET PLUS INCOME(SM) -- This strategy provides the security of
principal that the Money Market Fund offers plus the opportunity for greater
income by reinvesting dividends into one or more of the Bond Funds.
    An initial investment of $5,000 or more is made in the Money Market Fund and
monthly dividends are then reinvested into a Bond Fund chosen by you at such
Bond Fund's current offering price. Money Market Plus Income(SM) allows
investors the opportunity to capitalize on shifts in interest rates.
    When short-term interest rates increase, so do Money Market dividends. At
the same time, Bond Fund share prices
 
                                       20
<PAGE>   24
 
                         NATIONWIDE(R) FAMILY OF FUNDS
 
generally decrease. So, with Money Market Plus Income(SM), when
you earn higher Money Market dividends, you can generally purchase more Bond
Fund shares at lower prices. Conversely, when interest rates and Money Market
dividends decrease, Bond Fund share prices usually increase -- you will
automatically buy fewer Bond Fund shares at higher prices. Money Market Plus
Income(SM) provides investors with stability of principal, instant liquidity
through Money Market free checking ($500 minimum), telephone redemption, or NAS
NOW, and the opportunity for greater income. NOTE: Money Market Fund dividends
reinvested into one of the Bond Funds are subject to applicable sales charges.
 
3 AUTOMATIC ASSET ACCUMULATION(SM) -- This is a systematic investment strategy
which combines automatic monthly transfers from your personal checking account
to your mutual fund account with the concept of Dollar Cost Averaging. With this
strategy, you invest a fixed amount monthly over an extended period of time,
during both market highs and lows. Dollar Cost Averaging can allow you to
achieve a favorable average share cost over time since your fixed monthly
investment buys more shares when share prices fall during low markets, and fewer
shares at higher prices during market highs. Although no formula can assure a
profit or protect against loss in a declining market, systematic investing has
proven a valuable investment strategy in the past.
    You can get started with Automatic Asset Accumulation(SM) for as little as
$25 a month (Stock Funds), or $100 a month (Bond Funds or Money Market Fund).
Another way to take advantage of the benefits that Dollar Cost Averaging can
offer is through the Money Market Plus Growth(SM) or Money Market Plus
Income(SM) investor strategies.
 
4 AUTOMATIC ASSET ALLOCATION(SM) -- This strategy is for investors who want to
set up an account in more than one of our Funds. This allows you to diversify
further your portfolio to accommodate your unique needs. If you set up your
account with Automatic Asset Accumulation(SM), additional investments can be
automatically allocated among the Funds based upon your initial percentage. You
must satisfy the account minimum requirements (subsequent investments) of each
Fund in which you invest. Changes to your percentage allocation can be made by
calling toll-free 1-800-848-0920.
 
5 AUTOMATIC ASSET TRANSFER(SM) -- This systematic investment plan is designed
especially for investors who want to invest $5,000 or more in the Stock or Bond
Funds, but not all at one time. An initial investment of $5,000 or more is made
in the Money Market Fund, then a fixed amount that you predetermine is
transferred systematically monthly or quarterly into another Fund ($50 minimum
transfer, $100 minimum for the Bond Funds). The money is transferred on the 25th
day of the month or on the business day preceding the 25th day. This strategy
can provide investors with the benefits of Dollar Cost Averaging through an
opportunity to achieve a favorable average share cost over time. With this plan,
your fixed monthly or quarterly transfer from the Money Market to any Fund you
select buys more shares when share prices fall during low markets and fewer
shares at higher prices during market highs. Although no formula can assure a
profit or protect against loss in a declining market, systematic investing has
proven a valuable investment strategy in the past.
    Those who have a more conservative outlook on investing can transfer smaller
sums monthly and spread the transfer of assets into another Fund over a longer
period of time, while those with a more aggressive outlook can transfer larger
sums over a shorter period. Either way, you receive the added benefits of
current rates paid on the portion of your investment in the Money Market, along
with the stability offered by the Money Market's fixed share price.
 
6 AUTOMATIC WITHDRAWAL PLAN(SM) ($50 OR MORE) -- You may have checks for any
fixed amount of $50 or more automatically sent bi-monthly, monthly, quarterly,
three times/year, semi-annually or annually, to you (or anyone you designate)
from your account.
    NOTE: If your monthly withdrawals exceed the monthly dividends from your
account, you will be depleting principal, which will reduce your future dividend
potential.
 
INVESTOR PRIVILEGES
 
The Funds offer the following privileges to shareholders. Additional information
may be obtained by calling Nationwide Advisory Services, Inc. (NAS) toll-free at
1-800-848-0920.

<PAGE>   25
 
                         NATIONWIDE(R) FAMILY OF FUNDS
 
exactly the same as that of the Fund account from which the exchange is made,
and the amount you exchange must meet the applicable minimum investment of the
Fund being purchased. (Shares of the Fund exchanged to must be registered in the
shareholder's state of residence).
 
EXCHANGES AMONG THE FUNDS
 
   
Class D Shares of the Funds generally may be exchanged among any of Nationwide's
Family of Funds without sales charge.
    
    Exchanges from the Money Market Fund to any other Fund, however, will be
subject to applicable sales charges, see "Sales Charge Schedule and Available
Discounts" on page 19.
    The Trust reserves the right to change the exchange privilege upon at least
60 days written notice to the shareholder.
 
EXCHANGES MAY BE MADE THREE CONVENIENT WAYS:
 
BY TELEPHONE
 
    NAS NOW -- You can automatically process exchanges by calling
    1-800-637-0012, 24 hours a day, seven days a week. However, if you declined
    the option in the application, you will not have this automatic exchange
    privilege. NAS NOW also gives you quick, easy access to mutual fund
    information. Select from a menu of choices to conduct transactions and hear
    fund price information, mailing and wiring instructions as well as other
    mutual fund information.
 
    CUSTOMER SERVICE LINE -- By calling 1-800-848-0920, you may exchange shares
    by telephone if the shares are not issued in certificate form. Requests may
    be made only by the account owner(s). You must call our toll-free number by
    4:00 p.m. Eastern Time to receive that day's closing share price.
 
    NAS may record all instructions to exchange. NAS reserves the right at any
    time without prior notice to suspend, limit or terminate the telephone
    exchange privilege or its use in any manner by any person or class.
 
    The funds will employ the same procedure described under "How to Sell
    (Redeem) Shares" on page 18 to confirm that the instructions are genuine.
 
BY MAIL -- An exchange may be made by writing to Nationwide Advisory Services,
Inc., Three Nationwide Plaza, P.O. Box 1492, Columbus, Ohio 43216-1492. Please
be sure that your letter is signed by all owners of the account and that your
account number and the Fund you wish to exchange to are included.
 
ALTERNATE METHODS -- In the event of significant market activity, it may be
difficult to reach NAS by telephone. If so, an investor may choose to use
alternate methods to contact NAS such as sending instructions by a special
delivery service or by facsimile (FAX) machine (614-249-8705). If you use the
FAX method, NAS reserves the right to require the original document.
 
3 INSURANCE PROCEEDS OR BENEFITS DISCOUNT PRIVILEGE (CLASS D SHARES) -- If the
funds used to purchase shares come from proceeds or benefits of an insurance
policy issued by any of the Nationwide Enterprise of insurance companies or
their affiliated companies, the sales charge is one-half the rate established,
provided the purchase is made within 60 days after receipt of the proceeds or
benefits.
 
4 LETTER OF INTENT (LOI) DISCOUNT -- This discount permits you to purchase Class
D Shares at a reduced cost during a 13-month period if the amount invested, or
the value of shares held by you and other family members of your household, plus
the amount invested (excluding investments in Nationwide Money Market Fund),
equals or exceeds $50,000. LOI is not a binding obligation upon the investor to
buy the shares. It is merely a statement of intent.
    By marking the appropriate box and signing the application, you indicate
your intention to complete the appropriate LOI. The LOI will be completed when
your new investments, together with the value of all existing shares held by
you, your spouse, minor children, and other family members of your household,
total an amount equal to the amount checked on the application. You obtain a
reduced sales charge on each share purchased during the 13-month period. The LOI
may be backdated, up to 90 days, to include previous purchases under the reduced
sales charge available under the LOI.
    If the intended investment is not completed, the investor will be asked to
pay the difference between the sales charge actually paid and the sales charge
due on the amount invested according to the "Sales Charge Schedule," page 19. If
the difference is not paid within 20 days after written request, the investor
irrevocably constitutes and appoints NAS as their attorney-in-fact, with full
power of substitution, to redeem an appropriate number of shares from their
account to cover the amount due. For more details on the LOI Discount, call
1-800-848-0920.

Shares for which you paid sales charges, you have a one-time privilege to
reinvest all or part of the redemption proceeds in any of the Class D Shares
without a sales charge, within 30 days after the effective date of the
redemption.
    If you realize a gain on your redemption, the transaction is taxable and
reinvestment will not alter any capital gains tax payable. If you realize a loss
and you use the reinstatement privilege, some or all of the loss will not be
allowed as a tax deduction depending upon the amount reinvested.

shares) will be mailed to you following each year-end. Average cost can only be
calculated on accounts opened on or after January 1, 1984. Fiduciary accounts
and accounts with shares acquired by gift, inheritance, transfer, or by any
means other than a purchase cannot be calculated.
    Average cost is one of the IRS approved methods available to compute gains
or losses. You may wish to consult a tax advisor on the other methods available.

OTHER SERVICES
 
   
Under the terms of a Fund Administration Agreement, NAS also provides various
administrative and accounting services, including daily valuation of the Funds'
shares and preparation of financial statements, tax returns, and regulatory
reports. For these services, each Fund pays NAS an annual fee based on each
Fund's average daily net assets in the amount of 0.07% up to $250 million in
assets, 0.05% on the next $750 million and 0.04% on assets of $1 billion and
more.
    
 
TRANSFER AND DIVIDEND DISBURSING AGENT
NAS, through its wholly-owned subsidiary, Nationwide Investors Services, Inc.
(NISI), serves as transfer agent and dividend

                         NATIONWIDE(R) FAMILY OF FUNDS
 
   
disbursing agent for the Trust. For these services, NAS receives an annual per
account fee from each of the Funds; $16 per Stock Fund account, $18 per Bond
Fund account and $27 per Money Market Fund account.
    
 
   
DISTRIBUTIONS AND TAXES
    
 
INCOME DIVIDENDS AND CAPITAL GAINS
   
Substantially all of the net investment income, if any, will be paid to
shareholders quarterly by the Stock Funds and at the end of each month by the
Bond and Money Market funds. Checks will not be mailed for dividends of less
than $5. These dividends will be reinvested in the form of additional shares and
you will receive a confirmation showing the transaction.
    
   
    In those years in which sales of a Fund's portfolio securities result in net
realized capital gains, these gains will be declared and cause to be paid to
shareholders in December.
    
 
FEDERAL TAXES
   
Each of the Funds intends to qualify for treatment under subchapter M of the
Internal Revenue Code of 1986, as amended, (the "Code") and, therefore, must
distribute all or substantially all net investment income and capital gains to
shareholders annually. In general, if a Fund distributes all of its net
investment income, it is not required to pay any federal income taxes. In
addition to federal income tax, if a Fund fails to distribute the required
portion of investment income or capital gains in any year, it will be subject to
a non-deductible 4% excise tax on the amount which it failed to distribute. Each
Fund intends to make distributions in sufficient amounts to avoid the imposition
of this excise tax.
    
   
    Dividends paid by each of the Funds (with the exception of the Tax-Free
Income Fund) are taxable as income to the shareholder for federal income tax
purposes. For corporate shareholders, a portion of each year's distribution may
be eligible for the corporate dividend received deduction.
    
   
    Dividends paid by the Tax-Free Income Fund will be exempt from federal
income tax to the extent that the income of the Fund is derived from bonds that
qualify for such exemption. Some portion of the income from the Tax-Free Income
Fund may be taxable annually. The taxable portion of each distribution will be
based on the ratio, each year, between the Fund's taxable income and total
income. This ratio shall be determined within 60 days following the close of the
taxable year. The annual ratio may differ significantly from the ratio for the
period actually covered by each distribution.
    
   
    The Taxpayer Relief Act of 1997 has substantially changed the manner in
which the income tax on net long-term capital gains is computed for individuals.
For corporations, net long-term capital gains are taxed at the same rates as
ordinary income. The following is a summary of the new rules for the taxation of
net long-term capital gains, which are applicable to individuals but not
corporations for sales and exchanges after May 6, 1997.
    
   
    For investments held for more than 18 months (12 months if the investment
was sold after May 6 and before July 29, 1997), the top net long-term capital
gain rate is 20%. For taxpayers who are in the 15% regular tax bracket for 1997,
the top net long-term capital gain rate is 10%.
    
   
    Commencing with sales after July 28, 1997, gain from assets that are held
for more than 12 months but not more than 18 months is treated as mid-term gain.
The top tax rate for mid-term gain is 28%.
    
   
    If the investor's regular tax rate is lower than the top long-term capital
gain rate, the tax is computed using the regular tax rates.
    
    The Funds will annually report to each shareholder that shareholder's
portion of the net income and capital gain of each Fund, for inclusion in the
shareholder's income.
    Individual and corporate shareholders may be subject to the Alternative
Minimum Tax ("AMT") if their Alternative Minimum Taxable Income ("AMTI") exceeds
the exemption amounts set forth in Section 55 of the Code. The AMT, at rates as
high as 28% for individuals and 20% for corporations, is reduced by the regular
tax due for the year. AMTI is the taxpayer's taxable income for the year for
regular tax purposes, increased by the tax preferences described in Section 57
of the Code and adjusted as described in Section 56 of the Code. Preferences
include interest from Specified Private Activity Bonds, as defined in Section 57
(a) (5) (C) of the Code. Bonds of this type may be held by one or more of the
Funds from time to time.
    A shareholder may be subject to federal backup withholding at a rate of 31%
of each distribution if the shareholder fails to certify that the taxpayer
identification number given is correct and that the shareholder is not subject
to such withholding because of underreporting of income (or if the Internal
Revenue Service gives notice that such certifications are not accurate).
 
STATE AND LOCAL TAXES
Distributions to shareholders of the Funds may be subject to state and local
taxes, even if not subject to Federal income taxes. These laws vary, and you are
advised to consult a tax adviser regarding such taxes.
 
REDEMPTIONS OF SHARES
Redeeming shares may result in a capital gain or loss for tax purposes. For your
convenience, NAS provides a year-end statement, reflecting your taxable gain or
loss for the year based

25.)
 
TAX ADVANTAGES OF THE
TAX-FREE INCOME FUND
 
The yield on taxable securities is normally higher than on tax-exempt securities
of comparable quality and maturity. However, you can determine whether a
tax-free investment provides a higher after-tax yield or return than an
investment subject to tax by using the following formula:
 
<TABLE>
<C>                     <C>  <S>
    Tax-Free Yield           What you must earn
- -----------------------  =   on a taxable investment
 100%--[Your Tax Rate]       to equal this tax-free yield
</TABLE>
 
    By using current tax-free yields and your own tax rate in the formula above,
you can make an informed investment decision. This formula will not be
applicable if you are subject to the Alternative Minimum Tax.
    The tables on the following page show the advantages of investing in
tax-exempt obligations for those individuals in higher tax brackets. Taxable
yields are compared to equivalent tax-free yields. The first table is based on
the maximum marginal tax rates currently in effect under the Internal Revenue
Code for the 1997 tax year at various levels of taxable income.
   
    For example, if you file a joint return with an adjusted gross income of
$50,000, you are in the 28% tax bracket. A 5% tax-free yield would be equivalent
to an 6.9% taxable yield for you.
    Over the long term, the effect of tax-free investing is significant. With
the Tax-Free Income Fund, dividends can be automatically reinvested and allowed
to accumulate on a tax-free basis. You can see this advantage in the "How a
$20,000 Investment Grows at 5% Tax-Free vs. 5% Taxable" table below:

PERFORMANCE ADVERTISING
FOR THE FUNDS
 
FUND PERFORMANCE ADVERTISING
The Funds may use historical performance in advertisements, sales literature,
semi-annual and annual reports and the prospectus. Such figures will include
quotations of average annual (compound) total return for the most recent one,
five, and ten-year periods (or the life of the Fund if less). Average annual
(compound) total return represents the average annual percentage change in the
value of an investment for the specified periods assuming a redemption of the
investment at the end of such periods. It reflects the changes in share price
and assumes reinvestment of all dividends and distributions at net asset value.
Average annual (compound) total return reflects the effect of maximum sales
charges.

    The Funds may also choose to show nonstandard returns including total return
and simple average total return. Nonstandard returns may or may not reflect
reinvestment of all dividends and capital gains. In addition, sales charge
assumptions will vary. Initial sales charge percentages decrease as amounts
invested increase, as outlined on page 19 of this prospectus, therefore, returns
increase as sales charges decrease.

    Total return represents the cumulative percentage change in the value of an
investment over time, calculated by subtracting the original investment from the
redeemable value and dividing the result by the original amount of the
investment. The simple average total return is calculated by dividing total
return by the number of years in the period, and unlike average annual
(compound) total return, does not reflect compounding.

    The Bond Funds may advertise their SEC yields. The SEC yield is based on a
30-day period. This yield takes into account the yields to maturity on all debt
instruments and all dividends accrued on equity securities, since equity
securities do not have maturity dates. The SEC yield is computed by dividing the
net investment income per share earned during the 30-day period by the maximum
offering price per share on the last day of the period.

    The Money Market Fund may advertise current seven-day yield quotations
computed by determining the net change, exclusive of capital changes, in the
value of a hypothetical pre-existing account having a balance of one share at
the beginning of the base period to obtain a base period return and then
multiplying the base period return by (365/7). For purposes of this calculation,
the net change in account value reflects the value of additional shares
purchased with dividends from the original share, and dividends declared on both
the original share and any such additional shares. The Money Market's effective
yield represents a compounding on an annualized basis of the current yield
quotations.
 
RANKINGS AND RATINGS IN FINANCIAL PUBLICATIONS

The Funds may report their performance relative to other mutual funds or
investments. The performance comparisons are made to: other mutual funds with
similar objectives; other mutual funds with different objectives; or, to other

closed-end funds; market indexes; fixed-rate, insured bank CDs, bank money
market deposit accounts and passbook savings; and the Consumer Price Index.

    Normally these rankings and ratings are published by independent tracking
services and publications of general interest including, but not limited to:

FINANCIAL HIGHLIGHTS

Financial highlights are not available for the Fund, because the Fund has not
yet commenced operations.
   

INVESTMENT OBJECTIVE AND POLICIES

The Fund's investment objective is to provide investment results that correspond
to the price and yield performance of publicly traded common stocks, as
represented by the Standard & Poor's 500 Composite Stock Price Index.***

The Fund attempts to duplicate the investment results of the Index, which is
composed of 500 selected common stocks, most of which are listed on the New York
Stock Exchange. Standard & Poor's ("S&P") chooses the stocks to be included in
the Index solely on a statistical basis. The Fund attempts to be fully invested
at all times in the stocks that comprise the Index and stock index futures as
described below, and in any event, at least 80% of the Fund's net assets will be
so invested. Inclusion of a stock in the Index in no way implies an opinion by
S&P as to its attractiveness as an investment. The Fund uses the Index as the
standard performance comparison because it represents approximately 70% of the
total market value of all common stocks and is well known to investors. An
investment in the Fund involves risks similar to those of investing in stocks,
i.e., the possibility that stock prices in general will decline over short or
even extended periods of time.

The weightings of stocks in the Index are based on each stock's relative total
market capitalization; that is, its market price per share times the number of
shares outstanding. Because of this weighting, as of _____________________,
approximately ____% of the Index was composed of the 50 largest companies. The
Fund's subadviser generally select stocks for the Fund's portfolio in the order
of their weightings in the Index beginning with the heaviest weighted stocks.
With respect to the Fund's assets invested in the stocks in the Index, the
percentage of such assets invested in each stock is approximately the same as
the percentage it represents in the Index.

No attempt is made to manage the Fund in the traditional sense using economic,
financial and market analysis. The Fund is managed using a computer program to
determine which stocks are to be purchased or sold to replicate the Index to the
extent feasible. From time to time, administrative

adjustments may be made in the Fund's portfolio because of changes in the
composition of the Index, but such changes should be infrequent.

The Fund believes that the indexing approach described above is an effective
method of substantially duplicating percentage changes in the Index. It is a
reasonable expectation that there will be a close correlation between the Fund's
performance and that of the Index in both rising and falling markets. The Fund
will attempt to achieve a correlation between the performance of its portfolio
and that of the Index of at least 0.95, without taking into account expenses. A
correlation of 1.00 would indicate perfect correlation, which would be achieved
when the Fund's net asset value, including the value of its dividends and
capital gains distributions, increases or decreases in exact proportion to
changes in the Index. The Fund's ability to correlate its performance with the
Index, however may be affected by, among other things, changes in securities
markets, the manner in which the Index is calculated by S&P and the timing of
purchases and redemptions. In the future, the Trust's Board of Trustees may
select another index if such a standard of comparison is deemed to be more
representative of the performance of common stocks.

The Fund's ability to duplicate the performance of the Index also depends to
some extent on the size of the Fund's portfolio and the size of cash flows into
and out of the Fund. Investment changes to accommodate these cash flows are made
to maintain the similarity of the Fund's portfolio to the Index to the maximum
practicable extent.

From time to time to increase its income, the Fund may lend securities from its
portfolio. When the Fund has cash reserves, the Fund may invest in money market
instruments consisting of U.S. government securities, time deposits,
certificates of deposit, bankers' acceptances, high-grade commercial paper, and
repurchase agreements. See the Statement of Additional Information for a
description of these instruments. The Fund also may purchase stock index futures
in anticipation of taking a market position when, in the opinion of the Fund's
subadviser, available cash balances do not permit an economically efficient
trade in the cash market. The Fund also may sell (write) stock index futures to
terminate existing positions it may have as a result of its purchases of stock
index futures. See also "INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS"
below.
    

There can be no guarantee that the Fund's objective will be achieved. The
investment objective of the Fund is not fundamental and shareholder approval is
not required to change the Fund's investment objective.

MANAGEMENT OF THE FUND

The Adviser provides investment management evaluation services to the Fund in
initially selecting and monitoring on an ongoing basis the performance of a
subadviser to manage the Fund's portfolio. The Adviser has selected The Dreyful
Corporation to be the subadviser (the "Subadviser") of the Fund. See "MANAGEMENT
OF THE TRUST - MANAGEMENT OF THE FUND-THE SUBADIVSER" below for further
information.

<PAGE>   38



INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS
   

GENERAL - The Fund's net asset value per share should be expected to fluctuate.
Investors should consider the Fund as a supplement to an overall investment
program and should invest only if they are willing to undertake the risks
involved.

EQUITY SECURITIES - Equity securities fluctuate in value, often based on factors
unrelated to the value of the issuer of the securities, and such fluctuations
can be pronounced. Changes in the value of the Fund's investments will result in
changes in the value of its shares and thus the Fund's total return to
investors.
    

FOREIGN SECURITIES - Since the stocks of some foreign issuers are included in
the Index, the Fund's portfolio may contain securities of such foreign issuers
which may subject the Fund to additional investment risks with respect to those
securities that are different in some respects from those incurred by a fund
which invests only in securities of domestic issuers. Such risks include
possible adverse political and economic developments, seizure or nationalization
of foreign deposits or adoption of governmental restrictions which might
adversely affect the payment of principle and interest on the foreign securities
or restrict the payment of principal and interest to investors located outside
the country of the issuer, whether from currency blockage or otherwise.

USE OF DERIVATIVES - The Fund may invest, to a limited extent, in derivatives
("Derivatives"). These are financial instruments which derive their performance,
at least in part, from the performance of an underlying asset or index. The
Derivatives the Fund may use include stock index futures.  While Derivatives can
be used effectively in furtherance of the Fund's investment objective, under
certain market conditions, they can increase the volatility of the Fund's net
asset value, can decrease the liquidity of the Fund's portfolio and make more
difficult the accurate pricing of the Fund's portfolio.

Although the Fund will not be a commodity pool, Derivatives subject the Fund to
the rules of the Commodity Futures Trading Commission which limit the extent to
which the Fund can invest in certain derivatives. The Fund may invest in stock
index futures contracts for hedging purposes without limit. However, the Fund
may not invest in such contracts for other purposes if the sum of the amount of
initial margin deposits, other than for bona fide hedging purposes, exceeds 5%
of the liquidation value of the Fund's assets, after taking into account
unrealized profits and unrealized losses on such contracts.

BORROWING MONEY- The Fund is permitted to borrow money only for temporary or
emergency (not leveraging) purposes, in an amount up to 5% of the value of its
total assets (including the amount borrowed) valued at the lesser of cost or
market, less liabilities (not including the amount borrowed) at the time the
borrowing is made.

LENDING PORTFOLIO SECURITIES - the fund may lend securities from its portfolio
to brokers, dealers and other financial institutions needing to borrow
securities to complete certain transactions. The Fund

                                        5

<PAGE>   39



continues to be entitled to payments in amounts equal to the interest, dividends
or other distributions payable on the loaned securities which affords the Fund
an opportunity to earn interest on the amount of the loaned and income on the
loaned securities' collateral. Loans of portfolio securities may not exceed 30%
of the value of the Fund's total assets, and the Fund will receive collateral
consisting of cash, U.S. Government securities or irrevocable letters of credit
which will be maintained at all times in an amount equal to at least 100% of the
current market value of the loaned securities. Such loans are terminable by the
Fund at any time upon specified notice. The Fund might experience risk of loss
if the institution with which it has engaged in a portfolio loan transaction
breaches its agreement with the Fund.
   

NON-DIVERSIFIED STATUS - The classification of the Fund as a "non-diversified"
portfolio means that the proportion of the Fund's assets that may be invested in
the securities of a single issuer is not limited by the Investment Company Act
of 1940 Act. A "diversified" investment company is required by the 1940 Act
generally, with respect to 75% of its total assets, to invest not more than 5%
of such assets in the securities of a single issuer. The Fund is not so limited.
Since a relatively high percentage of the Fund's assets may be invested in the
securities of a limited number of issuers, some of which may be within the same
economic sector, the Fund's portfolio may be more sensitive to the changes in
market value of a single issuer or industry. However, to meet Federal tax
requirements, at the close of each quarter the Fund may not have more than 25%
of its total assets invested in any one issuer and, with respect to 50% of total
assets, not more than 5% of its total assets invested in any one issuer. These
limitations do not apply to U.S. Government securities.

MANAGEMENT OF THE TRUST

TRUSTEES AND OFFICERS

The business and affairs of the Trust are managed under the direction of its
Board of Trustees.

The Board of Trustees sets and reviews policies regarding the operation of the
Trust, whereas the officers perform the daily functions of the Trust. Unless so
required by the Trust's Declaration of Trust or By-Laws or by Ohio law, at any
given time, all of the Trustees may not have been elected by the Shareholders of
the Trust. The Trust will be managed by the Trustees in accordance with the laws
of Ohio governing business trusts. The Trustees, in turn, elect the officers of
the Trust to supervise its day-to-day operations.
    

MANAGEMENT OF THE FUND

THE ADVISER - Under the terms of the Investment Advisory Agreement, NAS, Three
Nationwide Plaza, Columbus, Ohio 43215, oversees the investment of the assets
for the Fund and supervises the daily business affairs of the Fund. Subject to
the supervision and direction of the Trustees, the Adviser also evaluates and
monitors the performance of the subadviser. The Adviser is also authorized to
select and place portfolio investments on behalf of the Fund, however the
Adviser does not intend to do so at this time.

                                        6

<PAGE>   40



The Adviser has applied to the Securities and Exchange Commission for an
exemptive order which, if granted, will allow the Adviser to appoint, replace or
terminate the subadviser without approval of shareholders, subject to receipt of
such an order, any change in the Subadviser will be communicated to shareholders
within 60 days of such change and all changes will be approved by the Trust's
Board of Trustees, including a majority of the Trustees who are not interested
persons of the Trust or the Adviser. The order, if granted, is intended to
facilitate the efficient operation of the Fund and afford the Trust increased
management flexibility. Prior to receiving the exemptive order, the Adviser will
not appoint, replace or terminate the Subadviser or materially amend any
subadvisory agreement without obtaining the approval of shareholders.

The Adviser provides to the Fund investment management evaluation services
principally by performing initial due diligence on prospective Subadvisers for
the Fund and thereafter monitoring the performance of the Subadviser through
quantitative and qualitative analysis as well as periodic in-person, telephonic
and written consultations with the Subadviser. The Adviser has responsibility
for communicating performance expectations and evaluations to the Subadviser and
ultimately recommending to the Trust's Board of Trustees whether the
Subadviser's contract should be renewed, modified or terminated however, the
Adviser does not expect to recommend frequent changes of subadvisers. The
Adviser will regularly provide written reports to the Board of Trustees
regarding the results of its evaluation and monitoring functions. Although the
Adviser will monitor the performance of the Subadviser, there is no certainty
that the Subadviser or the Fund will obtain favorable results at any given time.
   

The Adviser, an Ohio corporation, is a wholly owned subsidiary of Nationwide
Life Insurance Company, which is owned by Nationwide Financial Services, Inc.
("NFS"). NFS, a holding company, has two classes of common stock outstanding
with different voting rights enabling Nationwide Corporation (the holder of all
the outstanding Class B Common Stock) to control NFS. Nationwide Corporation is
also a holding company in the Nationwide Insurance Enterprise. The Fund pays the
Adviser a fee at the annual rate of .13% of the Fund's average daily net assets.
    

The Adviser may from time to time waive some or all of its investment advisory
fee or other fees. The waiver of such fees will cause the total return and yield
of the Fund to be higher than they would otherwise be in the absence of such a
waiver.

THE SUBADVISER - Subject to the supervision of the Adviser and the Board of
Trustees, the Subadviser manages the Fund's assets in accordance with the Fund's
investment objective and policies. The Subadviser shall make investment
decisions for the Fund, and in connection with such investment decisions shall
place purchase and sell orders for securities. For the investment management
services it provides to the Fund, the Subadviser receives an annual fee from the
Adviser






                                        7

in the following amounts:

         .07% on assets up to $250 million 
         .06% on assets of $250 million up to $500 million 
         .05% on assets of $500 million up to $1 billion 
         .04% on assets of $1 billion and more.
    

Below is a brief description of the Subadviser.

_______________. Draftees is a wholly-owned subsidiary of Mellon Bank, N.A.,
which is a wholly-owned subsidiary of Mellon Bank Corporation.

DISTRIBUTION PLAN
   

The Trust has adopted a Distribution Plan (the "Plan") under Rule 12b-1 of the
Investment Company Act of 1940 which permits the Fund to compensate the
Distributor, Nationwide Advisory Services, Inc. ("NAS") for expenses associated
with distribution of its shares. Under the Plan, the Fund pays NAS compensation
accrued daily and paid monthly at a maximum rate of .07% of the Fund's average
daily net assets. Distribution expenses paid by NAS may include the costs of
printing and mailing prospectuses and sales literature to prospective investors,
advertising, and compensation to sales personnel and broker-dealers.
    

OTHER SERVICES

   
Under the terms of the Fund Administration Agreement, the Adviser also provides
various administrative and accounting services, including daily valuation of the
Fund's shares, preparation of financial statements, tax returns and regulatory
reports. For these services, the Fund pays NAS an annual fee based on the
Fund's average daily net assets in the amount of 0.05% on assets up to $1
billion and 0.04% on assets of $1 billion and more.
    

The Distributor, Nationwide Advisory Services, Inc. is located at Three
Nationwide Plaza, Columbus, Ohio 43215.

The Transfer and Dividend Disbursing Agent, Nationwide Investment Services, Inc.
("NISI"), Three Nationwide Plaza, Columbus, Ohio 43215, serves as transfer agent
and dividend disbursing agent for the Trust. The Fund pays NIS a fee for such
services at the annual rate of 0.01% of the Fund's average daily net assets. NIS
is a wholly owned subsidiary of the Adviser.

INVESTMENT IN FUND SHARES

An insurance company may purchase shares of the Fund using purchase payments
received on Contracts issued by Accounts. These Accounts are funded by shares of
the Fund. Funds of Funds may also purchase shares of the Fund for their
portfolios. There is no sales charge, and all shares are

                                        8

<PAGE>   42



sold at net asset value.

Shares of the Fund are currently sold only to separate accounts of Nationwide
Life Insurance Company and its wholly owned subsidiary Nationwide Life and
Annuity Insurance Company to fund the benefits under the Contract and to
affiliated Fund of Funds. The addresses for each of these entities is One
Nationwide Plaza, Columbus, Ohio 43215.

All investments in the Fund are credited to the shareholder's account in the
form of full and fractional shares of the Fund (rounded to the nearest 1/1000 of
a share). The Trust does not issue share certificates. Initial and subsequent
purchase payments allocated to the Fund are subject to the limits applicable to
the Contracts.

SHARE REDEMPTION

Redemptions are processed on any day on which the Trust is open for business and
are effected at net asset value next determined after the redemption order, in
proper form, is received by the Trust's transfer agent, NIS. The net asset value
per share for the Fund is determined once daily, as of the close of regular
trading on the New York Stock Exchange (generally 4:00 P.M. Eastern Time), on
each business day the New York Stock Exchange is open for regular trading, on
such other days as the Board determines and on any other day during which there
is a sufficient degree of trading in the Fund's portfolio securities that the
net asset value of the Fund is materially affected by changes in the value of
portfolio securities. The Trust will not compute net asset value on customary
national business holidays, including the following: Christmas, New Year's Day,
Martin Luther King's Birthday, Presidents' Day, Good Friday, Memorial Day,
independence Day, Labor Day, and Thanksgiving Day. The net asset value per share
is calculated by adding the value of all securities and other assets of the
Fund, deducting its liabilities, and dividing by the number of shares
outstanding.

In determining net asset value, portfolio securities listed on national
exchanges are valued at the last sales price on the principal exchange. If the
securities are traded only in the over-the-counter market, they are valued at
the last quoted bid price. Other portfolio securities are valued at the quoted
prices obtained from an independent pricing organization which employs a
combination of methods, including among others, the obtaining and comparison of
market valuations from dealers who make markets and deal in such securities and
the comparison of valuations with those of other comparable securities in a
matrix of such securities. The pricing service activities and results are
reviewed by an officer of the Trust. Securities for which market quotations are
not readily available, if any are valued at fair value in accordance with
procedures adopted by the Board of Trustees. Expenses and fees are accrued
daily.

The Trust may suspend the right of redemption only under the following unusual
circumstances:

- -    when the New York Stock Exchange is closed (other than weekends and
     holidays) or trading is restricted;

                                        9

<PAGE>   43




- -    when an emergency exists, making disposal of portfolio securities or the
     valuation of net assets not reasonably practicable; or

- -    during any period when the Securities and Exchange Commission has by order
     permitted a suspension of redemption for the protection of shareholder.

NET INCOME AND DISTRIBUTIONS

Substantially all of the net investment income, if any, of the Fund will be
declared and paid as dividends quarterly. Net realized capital gains, of the
Fund, if any, will be distributed at least annually.

ADDITIONAL INFORMATION

DESCRIPTION OF SHARES - The Declaration of Trust permits the Trustees to issue
an unlimited number of full and fractional shares of beneficial interest of the
Fund and to divide or combine such shares into a greater or lesser number of
shares without thereby changing the proportionate beneficial interests in the
Trust. Each share of the Fund represents an equal proportionate interest in the
Fund with each other share. The Trust reserves the right to create and issue
shares of a number of different portfolios or series. In that case, the shares
of each fund would participate equally in the earnings, dividends, and assets of
the particular portfolio or series, but shares of all funds would vote together
in the election of Trustees. Upon liquidation of a portfolio or series, its
shareholders are entitled to share pro rata in the net assets of such portfolio
or series available for distribution to shareholders.

VOTING RIGHTS - Shareholders are entitled to one vote for each share held.
Shareholders may vote in the election or removal of Trustees and on other
matters submitted to meetings of shareholders. No amendment may be made to the
Declaration of Trust without the affirmative vote of a majority of the
outstanding shares of the Trust. The Trustees may, however, amend the
Declaration of Trust without the vote or consent of shareholders to:

- -        designate series of the Trust;

- -        change the name of the Trust; or

- -        supply any omission, cure, correct or supplement any ambiguous,
         defective, or inconsistent provision to conform the Declaration of
         Trust to the requirements of applicable federal and state laws or
         regulations if they deem it necessary.

Shares have no pre-emptive rights. Shares are fully paid and nonassessable. In
regard to changes in fundamental investment restrictions, the right to vote is
limited to the holders of shares of the particular portfolio or series affected
by the proposal. When a majority is required, it means the lesser of 67% or more
of the shares present at a meeting when the holders of more than 50% of the

                                       10

<PAGE>   44



outstanding shares are present or represented by proxy, or more than 50% of the
outstanding shares.

SHAREHOLDER INQUIRIES - All inquiries regarding the Fund should be directed to
the Trust at the telephone number or address shown on the cover page of this
Prospectus.

PERFORMANCE ADVERTISING FOR THE FUND

The Fund may use historical performance in advertisements, sales literature, and
the prospectus. Such figures will include quotations of average annual total
return for the most recent one, five and ten year periods, or the life of the
Fund if less. Average annual total return represents the rate required each year
for an initial investment to equal the redeemable value at the end of the
specific period. Average annual total return reflects reinvestment of all
distributions.

TAX STATUS

The Trust's policy is to cause each fund to qualify as a regulated investment
company and to meet the requirements of Subchapter M of the Internal Revenue
Code (the "Code"). The Fund intends to distribute or substantially all, of its
taxable net investment income and capital gains to shareholders; therefore it is
expected that the Fund will not be required to pay any federal income taxes on
its investment income..

Because each portfolio or series of the Trust is treated as a separate entity
for purposes of the regulated investment company provisions of the Code, the
assets, income and distributions of the Fund are considered separately for
purposes of determining whether or not the Fund qualifies as a regulated
investment company. The Fund intends to comply with the diversification
requirements currently imposed by the Internal Revenue Service on separate
accounts of insurance companies as a condition of maintaining the tax-deferred
status of the Contracts. See the Statement of Additional Information for more
specific information.

The tax treatment of payments made by an Account to a Contractholder is
described in the separate account prospectus.

INVESTMENT OBJECTIVES AND POLICIES

ADDITIONAL INFORMATION ON PORTFOLIO INSTRUMENTS AND INVESTMENT POLICIES

The following information supplements the discussion of the Funds' investment
objectives and policies discussed in the prospectuses. The investment objectives
of each Fund are fundamental and may not be changed without shareholder
approval. The investment policy and types of permitted investments described
here may be changed without prior approval by the shareholders. There is no
guarantee that any of the Funds' investment objectives will be realized.

DEBT OBLIGATIONS. Each of the Funds (except S&P 500 Index Fund) may invest in
debt obligations. Debt obligations are subject to the risk of an issuer's
inability to meet principal and interest payments on its obligations ("credit
risk") and are subject to price volatility due to such factors as interest rate
sensitivity, market perception of the creditworthiness of the issuer, and
general market liquidity ("market risk"). Lower-rated securities are more likely
to react to developments affecting market and credit risk than are more highly
rated securities, which react primarily to movements in the general level of
interest rates.

         RATINGS AS INVESTMENT CRITERIA. High-quality and investment grade debt
obligations are characterized as such based on their ratings by nationally
recognized statistical rating organizations ("NRSROs"). In general, the ratings
of NRSROs represent the opinions of these agencies as to the quality of
securities that they rate. Such ratings, however, are relative and subjective,
and are not absolute standards of quality and do not evaluate the market risk of
the securities. These ratings are used by a Fund as initial criteria for the
selection of portfolio securities. Among the factors that will be considered by
NAS are the long-term ability of the issuer to pay principal and interest and
general economic trends. The Appendix to this Statement of Additional
Information contains further information about the rating categories of NRSROs
and their significance.

         Subsequent to its purchase by a Fund, an issue of securities may cease
to be rated or its rating may be reduced below the minimum required for purchase
by such Fund. In addition, it is possible that an NRSRO might not change its
rating of a particular issue to reflect subsequent events. None of these events
generally will require sale of such securities, but NAS will consider such
events in determining whether the Fund should continue to hold the securities.
In addition, to the extent that the ratings change as a result of changes in
such NRSROs or their rating systems, or due to a corporate reorganization, a
Fund will attempt to use comparable ratings as standards for its investments in
accordance with its investment objective and policies.

   
         DURATION. Duration is a measure of the expected life of a fixed income
security that was developed as a more precise alternative to the concept of the
"term of maturity." Duration incorporates a bond's yield, coupon interest
payments, final maturity and call features into one measure.

         Most debt obligations provide interest ("coupon") payments in addition
to a final ("par") payment at maturity. Some obligations also have call
provisions. Depending on the relative magnitude of these payments, the market
values of debt obligations may respond differently to changes in the level and
structure of interest rates.

         Traditionally, a debt security's "term to maturity" has been used as a
proxy for the sensitivity of the security's price to changes in interest rates
(which is the "interest rate risk" or "volatility" of the security). However,
"term to maturity" measures only the time until a debt security provides its
final payment, taking no account of the pattern of the security's payments prior
to maturity. Duration is a measure of the expected life of a fixed income
security on a present value basis. Duration takes the length of the time
intervals between the present time and the time that the interest and principal
payments are scheduled or, in the case of a callable bond, expected to be
received, and weights them by the present values of the cash to be received at
each future point in time. For any fixed income security with interest payments
occurring prior to the payment of principal,
    


                                       2
<PAGE>   48
   

duration is always less than maturity. In general, all other things being the
same, the lower the stated or coupon rate of interest of a fixed income
security, the longer the duration of the security; conversely, the higher the
stated or coupon rate of interest of a fixed income security, the shorter the
duration of the security.

         There are some situations where even the standard duration calculation
does not properly reflect the interest rate exposure of a security. For example,
floating and variable rate securities often have final maturities of ten or more
years; however, their interest rate exposure is not properly captured by
duration in the case of mortgage pass-through securities. The stated final
maturity of such securities is generally 30 years, but current prepayment rates
are more critical in determining the securities' interest rate exposure. In
these and other similar situations, the Adviser will use more sophisticated
analytical techniques that incorporate the economic life of a security into the
determination of its interest rate exposure.
    

MONEY MARKET INSTRUMENTS. Each Fund may invest in certain types of money market
instruments which may include the following types of instruments:

        -- obligations with remaining maturities of 13 months or less issued or
        guaranteed as to interest and principal by the U.S. Government, its
        agencies, or instrumentalities, or any federally chartered corporation,
        and for the Money Market and Bond Fund, obligations of the Canadian
        government and their provinces, their agencies and instrumentalities;

        -- repurchase agreements;

        -- certificates of deposit, time deposits and bankers' acceptances
        issued by domestic banks (including their branches located outside the
        United States (Eurodollars) and subsidiaries located in Canada),
        domestic branches of foreign banks (Yankees dollars), savings and loan
        associations and similar institutions;

        -- commercial paper, which are short-term unsecured promissory notes
        issued by corporations in order to finance their current operations.
        Generally the commercial paper will be rated within the top two rating
        categories by an NRSRO, or if not rated, is issued and guaranteed as to
        payment of principal and interest by companies which at the date of
        investment have outstanding debt issue with a high quality rating;

        -- short-term (maturity in 397 days or less) corporate obligations rated
        within the top two categories by an NRSRO;

        -- bank loan participation agreements representing obligations of
        corporations and banks having a high quality short-term rating, at the
        date of investment, and under which the Fund will look to the
        creditworthiness of the lender bank, which is obligated to make payments
        of principal and interest on the loan, as well as to creditworthiness of
        the borrower.

   
MORTGAGE AND ASSET-BACKED SECURITIES - The Bond Funds may each purchase
mortgage-backed securities. In addition, the Bond Fund may invest in
asset-backed securities. Mortgage-backed securities represent direct or indirect
participation in, or are secured by and payable from, mortgage loans secured by
real property, and include single- and multi-class pass-through securities and
collateralized mortgage obligations. Such securities may be issued or guaranteed
by U.S. Government agencies or instrumentalities or, in the case of the
Nationwide Bond Fund only, by 
    




                                       3
<PAGE>   49


private issuers, generally originators in mortgage loans, including savings and
loan associations, mortgage bankers, commercial banks, investment bankers, and
special purpose entities (collectively, "private lenders"). Mortgage-backed
securities issued by private lenders may be supported by pools of mortgage loans
or other mortgage-backed securities that are guaranteed, directly or indirectly,
by the U.S. Government or one of its agencies or instrumentalities, or they may
be issued without any governmental guarantee of the underlying mortgage assets
but with some form of non-governmental credit enhancement. These credit
enhancements may include letters of credit, reserve funds,
overcollateralization, or guarantees by third parties.

         Private lenders or government-related entities may also create mortgage
loan pools offering mortgage-backed securities where the mortgages underlying
these securities may be alternative mortgage instruments, that is, mortgage
instruments whose principal or interest payments may vary or whose terms to
maturity may be shorter than was previously customary. As new types of
mortgage-backed securities are developed and offered to investors, a Fund,
consistent with its investment objective and policies, may consider making
investments in such new types of securities.

         Asset-backed securities have structural characteristics similar to
mortgage-backed securities. However, the underlying assets are not first-lien
mortgage loans or interest therein, rather they include assets such as motor
vehicle installment sales contracts, other installment loan contracts, home
equity loans, leases of various types of property and receivables from credit
card and other revolving credit arrangements. Payments or distributions of
principal and interest on asset-backed securities may be supported by
non-governmental credit enhancements similar to those utilized in connection
with mortgage-backed securities.

         The yield characteristics of mortgage and asset-backed securities
differ from those of traditional debt obligations. Among the principal
differences are that interest and principal payments are made more frequently on
mortgage and asset-backed securities, usually monthly, and that principal may be
prepaid at any time because the underlying mortgage loans or other assets
generally may be prepaid at any time. As a result, if a Fund purchases these
securities at a premium, a prepayment rate that is faster than expected will
reduce yield to maturity, while a prepayment rate that is lower than expected
will have the opposite effect of increasing the yield to maturity. Conversely,
if a Fund purchases these securities at a discount, a prepayment rate that is
faster than expected will increase yield to maturity, while a prepayment rate
that is slower than expected will reduce yield to maturity. Accelerated
prepayments on securities purchased by the Fund at a premium also pose a risk of
loss of principal because the premium may not have been fully amortized at the
time the principal is prepaid in full. The market for privately issued mortgage
and asset-backed securities is smaller and less liquid than the market for
government sponsored mortgage-backed securities.
   

         There are a number of important differences among the agencies and
instrumentalities of the U.S. Government that issue mortgage-related securities
and among the securities that they issue. Mortgage-related securities issued by
GNMA include GNMA Mortgage Pass-Through Certificates (also known as "Ginnie
Maes") which are guaranteed as to the timely payment of principal and interest
by GNMA and such guarantee is backed by the full faith and credit of the United
States. GNMA certificates also are supported by the authority of GNMA to borrow
funds from the U.S. Treasury to make payments under its guarantee.
Mortgage-related securities issued by FNMA include FNMA Guaranteed Mortgage
Pass-Through Certificates (also known as "Fannie Maes") which are solely the
obligations of the FNMA and are not backed by or entitled to the full faith and
credit of the United States. Fannie Maes are guaranteed as to timely payment of
the principal and interest by FNMA. Mortgage-related securities issued by the
Federal Home Loan Mortgage Corporation ("FHLMC") include FHLMC Mortgage
Participation Certificates (also known as "Freddie Macs" or "PCs"). The FHLMC is
a corporate instrumentality of the United States, created pursuant to an Act of
Congress, which is owned entirely by Federal Home Loan Banks. Freddie Macs are
not guaranteed by the United States or by any Federal Home Loan Banks and do not
constitute a debt or obligation of the United States or of any Federal Home Loan
Bank. Freddie Macs entitle the holder to timely payment of interest, which is
guaranteed by the FHLMC. The FHLMC guarantees either ultimate
    


                                       4
<PAGE>   50

   
collection or timely payment of all principal payments on the underlying
mortgage loans. When the FHLMC does not guarantee timely payment of principal,
FHLMC may remit the amount due on account of its guarantee of ultimate payment
of principal at any time after default on an underlying mortgage, but in no
event later than one year after it becomes payable.

         STRIPPED MORTGAGE-BACKED SECURITIES. Stripped mortgage-backed
securities ("SMBS") are derivative multiclass mortgage securities. SMBS may be
issued by agencies or instrumentalities of the U.S. Government or by private
originators of, or investors in, mortgage loans, including savings and loan
associations, mortgage banks, commercial banks, investment banks and special
purpose entities of the foregoing. SMBS are usually structured with two classes
that receive different proportions of the interest and principal distributions
on a pool of mortgage assets. A common type of SMBS will have one class
receiving some of the interest and most of the principal from the mortgage
assets, while the other class will receive most of the interest and the
remainder of the principal. In the most extreme case, one class will receive all
of the interest (the interest-only or "IO" class), while the other class will
receive all of the principal (the principal-only or "PO" class). The yield to
maturity on an IO class is extremely sensitive to the rate of principal payments
(including prepayments) on the related underlying mortgage assets, and a rapid
rate of principal payments may have a material adverse effect on a Fund's yield
to maturity from these securities. If the underlying mortgage assets experience
greater than anticipated prepayments of principal, a Fund may fail to fully
recoup its initial investment in these securities even if the security is in one
of the highest rating categories.

         Although SMBS are purchased and sold by institutional investors through
several investment banking firms acting as brokers or dealers, these securities
were only recently developed. As a result, established trading markets have not
yet developed and, accordingly, certain of these securities may be deemed
"illiquid" and subject to a Fund's limitations on investment in illiquid
securities.

Each of the Bond Funds may invest in stripped mortgage-backed securities, which
receive differing proportions of the interest and principal payments from the
underlying assets. The market value of such securities generally is more
sensitive to changes in prepayment and interest rates than is the case with
traditional mortgage- and asset-backed securities, and in some cases the market
value may be extremely volatile. With respect to certain stripped securities,
such as interest-only ("IO") and principal-only ("PO") classes, a rate of
prepayment that is faster or slower than anticipated may result in a Fund
failing to recover all or a portion of its investment, even though the
securities are rated investment grade.
    

REPURCHASE AGREEMENTS. All of the Funds may enter into repurchase agreements
with certain banks or non-bank dealers. In connection with the purchase of a
repurchase agreement by a Fund, the Fund's custodian, or a subcustodian, will
have custody of, and will hold in a segregated account, securities acquired by
the Fund under a repurchase agreement. Repurchase agreements are contracts under
which the buyer of a security simultaneously commits to resell the security to
the seller at an agreed-upon price and date. Repurchase agreements are
considered by the staff of the Securities and Exchange Commission (the "SEC") to
be loans by a Fund. Repurchase agreements may be entered into with respect to
securities of the type in which the fund may invest or government securities
regardless of their remaining maturities. A Fund will require that additional
securities be deposited with its custodian if the value of the securities
purchased should decrease below resale price. Repurchase agreements involve
certain risks in the event of default or insolvency by the other party,
including possible delays or restrictions upon a Fund's ability to dispose of
the underlying securities, the risk of a possible decline in the value of 


                                       5
<PAGE>   51

the underlying securities during the period in which a Fund seeks to assert its
rights to the securities, the risk of incurring expenses associated with
asserting those rights and the risk of losing all or part of the income from the
repurchase agreement.

WHEN-ISSUED SECURITIES AND DELAYED-DELIVERY TRANSACTIONS. Each of the Funds
(except the S&P 500 Index Fund) may purchase securities on a "when-issued" or
"delayed delivery" basis (i.e., payment or delivery occurs beyond the normal
settlement date at a stated price and yield). When-issued transactions normally
settle within 45 days. The payment obligation and the interest rate, if
applicable, that will be received on when-issued securities are fixed at the
time the fund enters into the commitment to buy such securities. Due to
fluctuations in the value of securities purchased or sold on a when-issued or
delayed-delivery basis, the yields obtained on such securities may be higher or
lower than the yields available in the market on the dates when the investments
are actually delivered to the buyers.

   
         When a Fund agrees to purchase when-issued or delayed-delivery
securities, to the extent required by the SEC, the Funds custodian will set
aside permissible liquid assets equal to the amount of the commitment in a
segregated account. Normally, the custodian will set aside portfolio securities
to satisfy a purchase commitment, and in such a case a Fund may be required
subsequently to place additional assets in the segregated account in order to
ensure that the value of the account remains equal to the amount of such Fund's
commitment. It may be expected that the Fund's net assets will fluctuate to a
greater degree when it sets aside portfolio securities to cover such purchase
commitments than when it sets aside cash. In addition, because a Fund will set
aside cash or liquid portfolio securities to satisfy its purchase commitments in
the manner described above, such Fund's liquidity and the ability of NAS to
manage it might be affected in the event its commitments to purchase
"when-issued" securities ever exceeded 25% of the value of its total assets.
Under normal market conditions, however, a Fund's commitment to purchase
"when-issued" or "delayed-delivery" securities will not exceed 25% of the value
of its total assets. When the Fund engages in when-issued or delayed-delivery
transactions, it relies on the other party to consummate the trade. Failure of
the seller to do so may result in a Fund incurring a loss or missing an
opportunity to obtain a price considered to be advantageous.

The Funds will engage in "when-issued" or "delayed delivery" transactions only
for the purpose of acquiring portfolio securities consistent with the Funds'
investment objectives and policies and not for investment leverage. If the
Tax-Free Income Fund sells a "when-issued" or "delayed-delivery" security before
delivery, any gain would not be tax-exempt.
    

LENDING PORTFOLIO SECURITIES. Each Fund may lend its portfolio securities to
brokers, dealers and other financial institutions, provided it receives cash
collateral which at all times is maintained in an amount equal to at least 100%
of the current market value of the securities loaned. By lending its portfolio
securities, the Fund can increase its income through the investment of the cash
collateral. For the purposes of this policy, the Fund considers U.S. Government
securities or letters of credit issued by banks whose securities meet the
standards for investment by the Fund to be the equivalent of cash. From time to
time, the Fund may return to the borrower or a third party which is unaffiliated
with it, and which is acting as a "placing broker," a part of the interest
earned from the investment of collateral received for securities loaned.

         The SEC currently requires that the following conditions must be met
whenever portfolio securities are loaned: (1) a Fund must receive from the
borrower at least



                                       6
<PAGE>   52

100% cash collateral of the type discussed in the preceding paragraph; (2) the
borrower must increase such collateral whenever the market value of the
securities loaned rises above the level of such collateral; (3) a Fund must be
able to terminate the loan at any time; (4) a Fund must receive reasonable
interest on the loan, as well as any dividends, interest or other distributions
payable on the loaned securities, and any increase in market value; (5) a Fund
may pay only reasonable custodian fees in connection with the loan; and (6)
while any voting rights on the loaned securities may pass to the borrower, a
Fund's board of trustees must be able to terminate the loan and regain the right
to vote the securities if a material event adversely affecting the investment
occurs. These conditions may be subject to future modification. Loan agreements
involve certain risks in the event of default or insolvency of the other party
including possible delays or restrictions upon the Fund's ability to recover the
loaned securities or dispose of the collateral for the loan.

SPECIAL SITUATION COMPANIES. The Mid Cap Growth Fund may invest in the
securities of "special situation companies," which include those involved in an
actual or prospective acquisition or consolidation; reorganization;
recapitalization; merger, liquidation or distribution of cash, securities or
other assets; a tender or exchange offer; a breakup or workout of a holding
company; or litigation which, if resolved favorably, would improve the value of
the company's stock. If the actual or prospective situation does not materialize
as anticipated, the market price of the securities of a "special situation
company" may decline significantly. The Mid Cap Growth Fund believes, however,
that if NAS analyzes "special situation companies" carefully and invests in the
securities of these companies at the appropriate time, such Fund may achieve
capital growth. There can be no assurance however, that a special situation that
exists at the time the Mid Cap Growth Fund makes its investment will be
consummated under the terms and within the time period contemplated, if it is
consummated at all.

FOREIGN SECURITIES. The Mid Cap Growth Fund, Growth Fund and Nationwide Fund may
invest, directly or indirectly through the use of depository receipts, in
foreign securities. Investors in such Funds should recognize that investing in
foreign securities involves certain special considerations which are not
typically associated with investing in domestic securities. Since investments in
foreign companies will frequently involve currencies of foreign countries, and
since a Fund may hold securities and funds in foreign currencies, a Fund may be
affected favorably or unfavorably by changes in currency rates and in exchange
control regulations, if any, and may incur costs in connection with conversions
between various currencies. Most foreign stock markets, while growing in volume
of trading activity, have less volume than the New York Stock Exchange, and
securities of some foreign companies are less liquid and more volatile than
securities of comparable domestic companies. As non-U.S. companies are not
generally subject to uniform accounting, auditing and financial reporting
standards and practices comparable to those applicable to domestic issuers,
there may be less publicly available information about certain foreign
securities than about domestic securities. Fixed commissions on foreign
securities exchanges are generally higher than negotiated commissions on United
States exchanges, although each such Fund endeavors to achieve the most
favorable net results on its portfolio transactions. There is generally less
government supervision and regulation of securities exchanges, brokers and
listed companies in foreign countries than in the United States. In addition,
with respect to certain foreign countries, there is the possibility of exchange
control restrictions, expropriation or confiscatory taxation, and political,
economic or social instability, which could affect investments in those
countries. Foreign securities, such as those purchased by a Fund, may be subject
to foreign government 


                                       7
<PAGE>   53

taxes, higher custodian fees and dividend collection fees which could reduce the
yield on such securities.

   
         Certain foreign governments levy withholding taxes against dividend and
interest income. Although in some countries a portion of these taxes are
recoverable, the non-recovered portion of foreign withholding taxes will reduce
the income received from investments in such countries. However, these foreign
withholding taxes are not expected to have a significant impact on those Funds
for which the investment objective is to seek long-term capital appreciation and
any income should be considered incidental.
    

         Depository Receipts. As indicated in the Funds' Prospectus, the Stock
Funds may invest in foreign securities by purchasing depository receipts,
including American Depository Receipts ("ADRs") and European Depository Receipts
("EDRs") or other securities convertible into securities of issuers based in
foreign countries. These securities may not necessarily be denominated in the
same currency as the securities into which they may be converted. Generally,
ADRs, in registered form, are denominated in U.S. dollars and are designed for
use in the U.S. securities markets, while EDRs (also referred to as Continental
Depository Receipts ("CDRs")), in bearer form, may be denominated in other
currencies and are designed for use in European securities markets. ADRs are
receipts typically issued by a U.S. bank or trust company evidencing ownership
of the underlying securities. EDRs are European receipts evidencing a similar
arrangement. For purposes of a Fund's investment policies, ADRs and EDRs are
deemed to have the same classification as the underlying securities they
represent. Thus, an ADR or EDR representing ownership of common stock will be
treated as common stock.

         The Stock Funds may invest in depository receipts through "sponsored"
or "unsponsored" facilities. While ADRs and EDRs issued under these two types of
facilities are in some respects similar, there are distinctions between them
relating to the rights and obligations of ADR and EDR holders and the practices
of market participants.

         A depository may establish an unsponsored facility without
participation by (or even necessarily the acquiescence of) the issuer of the
deposited securities, although typically the depository requests a letter of
non-objection from such issuer prior to the establishment of the facility.
Holders of unsponsored ADRs and EDRs generally bear all the costs of such
facilities. The depository usually charges fees upon the deposit and withdrawal
of the deposited securities, the conversion of dividends into U.S. dollars, the
disposition of non-cash distributions, and the performance of other services.
The depository of an unsponsored facility frequently is under no obligation to
pass through voting rights to ADR and EDR holders in respect of the deposited
securities. In addition, an unsponsored facility is generally not obligated to
distribute communications received from the issuer of the deposited securities
or to disclose material information about such issuer in the U.S. and thus there
may not be a correlation between such information and the market value of the
depository receipts. Unsponsored ADRs and EDRs tend to be less liquid than
sponsored ADRs and EDRs, respectively.

         Sponsored ADR and EDR facilities are created in generally the same
manner as unsponsored facilities, except that the issuer of the deposited
securities enters into a deposit agreement with the depository. The deposit
agreement sets out the rights and responsibilities of the issuer, the
depository, and the ADR and EDR holders. With sponsored facilities, the issuer
of the deposited securities generally will bear some of the costs relating to
the facility (such as dividend payment fees of the depository), although ADR and
EDR holders continue to bear


                                       8
<PAGE>   54

certain other costs (such as deposit and withdrawal fees). Under the terms of
most sponsored arrangements, depositories agree to distribute notices of
shareholder meetings and voting instructions, and to provide shareholder
communications and other information to the ADR holders at the request of the
issuer of the deposited securities.

   
         EURODOLLAR AND YANKEE OBLIGATIONS. Eurodollar bank obligations are
dollar-denominated certificates of deposit and time deposits issued outside the
U.S. capital markets by foreign branches of U.S. banks and by foreign banks.
Yankee bank obligations are dollar-denominated obligations issued in the U.S.
capital markets by foreign banks.

         Eurodollar and Yankee bank obligations are subject to the same risks
that pertain to domestic issues, notably credit risk, market risk and liquidity
risk. Additionally, Eurodollar (and to a limited extent, Yankee) bank
obligations are subject to certain sovereign risks. One such risk is the
possibility that a sovereign country might prevent capital, in the form of
dollars, from flowing across their borders. Other risks include: adverse
political and economic developments; the extent and quality of government
regulation of financial markets and institutions; the imposition of foreign
withholding taxes, and the expropriation or nationalization of foreign issuers.
However, Eurodollar and Yankee bank obligations held in the Money Market Fund
will undergo the same credit analysis as domestic issues in which the Money
Market Fund invests, and will have at least the same financial strength as the
domestic issuers approved for the Money Market Fund.

         MUNICIPAL SECURITIES. As stated in the prospectus, the assets of the
Tax-Free Income Fund will be primarily invested in municipal securities.
Municipal securities include debt obligations issued by governmental entities to
obtain funds for various public purposes, such as the construction of a wide
range of public facilities, the refunding of outstanding obligations, the
payment of general operating expenses, and the extension of loans to other
public institutions and facilities. Private activity bonds that are issued by or
on behalf of public authorities to finance various privately-operated facilities
are included within the term municipal securities if the interest paid thereon
is exempt from federal taxes including the federal alternative minimum tax.

         Among other types of municipal securities, the Tax-Free Income Fund may
purchase short-term General Obligation Notes, Tax Anticipation Notes, Bond
Anticipation Notes, Revenue Anticipation Notes, Project Notes, Tax-Exempt
Commercial Paper, Construction Loan Notes and other forms of short-term
tax-exempt loans. Such instruments are issued with a short-term maturity in
anticipation of the receipt of tax funds, the proceeds of bond placements or
other revenues. In addition, the Tax-Free Income Fund may invest in other types
of tax-exempt instruments, such as municipal bonds, private activity bonds, and
pollution control bonds.

         Project Notes are issued by a state or local housing agency and are
sold by the Department of Housing and Urban Development. While the issuing
agency has the primary obligation with respect to its Project Notes, they are
also secured by the full faith and credit of the United States through
agreements with the issuing
    




                                       9

authority which provide that, if required, the federal government will lend the
issuer an amount equal to the principal of and interest on the Project Notes.

         As described in the prospectus, the two principal classifications of
municipal securities consist of "general obligation" and "revenue" issues. The
Tax-Free Income Fund may also acquire "moral obligation" issues, which are
normally issued by special purpose authorities. There are, of course, variations
in the quality of municipal securities, both within a particular classification
and between classifications, and the yields on municipal securities depend upon
a variety of factors, including the financial condition of the issuer, general
conditions of the municipal bond market, the size of a particular offering, the
maturity of the obligation and the rating of the issue. Ratings represent the
opinions of an NRSRO as to the quality of municipal securities. It should be
emphasized, however, that ratings are general and are not absolute standards of
quality, and municipal securities with the same maturity, interest rate and
rating may have different yields, while municipal securities of the same
maturity and interest rate with different ratings may have the same yield.
Subsequent to purchase, an issue of municipal securities may cease to be rated
or its rating may be reduced below the minimum rating required for purchase. NAS
will consider such an event in determining whether the Tax-Free Income Fund
should continue to hold the obligation.

         An issuer's obligations under its municipal securities are subject to
the provisions of bankruptcy, insolvency, and other laws affecting the rights
and remedies of creditors, such as the federal bankruptcy code, and laws, if
any, which may be enacted by Congress or state legislatures extending the time
for payment of principal or interest, or both, or imposing other constraints
upon the enforcement of such obligations or upon the ability of municipalities
to levy taxes. The power or ability of an issuer to meet its obligations for the
payment of interest on and principal of its municipal securities may be
materially adversely affected by litigation or other conditions.

         The Tax-Free Income Fund may invest in AMT bonds. An AMT bond is an
otherwise tax-exempt municipal bond whose interest is treated as a preference
item for purposes of computing the alternative minimum tax imposed on
individuals and corporations. Specifically, private activity bonds, other than
501(c)(3) bonds issued after August 7, 1986 that are not current refundings of
pre-1986 industrial development bonds are AMT bonds. A municipal bond is
considered to be a private activity bond if more than either 5% or $5 million of
the proceeds is used to finance a loan to any person other than a governmental
unit, or 10% or more of the proceeds of the issue is used in a trade or business
of any person other than a governmental entity and more than 10% of the issue is
secured by property or payments used in a private business.

         Municipal bonds that are private activity bonds will not be tax-exempt
unless they fall within the category of "qualified bonds" defined in the Tax
Code. Qualified bonds include issues for certain facilities such as airport
bonds, water and sewer service bonds, qualified single and multifamily housing
bonds, certain "small" industrial development bonds and bonds for local
furnishing of gas and electricity. Qualified bonds are also bonds for water,
solid waste facility bonds, docks and wharves issues and "enterprise zone"
bonds.

         In addition to the normal risks associated with bonds, there is a
slight risk of less active secondary market for AMT bonds. In general, a larger
secondary market will exist for AM bonds when the supply of municipal bonds is
tight.
    

CONVERTIBLE SECURITIES. The Mid Cap Growth Fund, Growth Fund and Nationwide Fund
may invest in convertible securities to the extent described in its Prospectus.
Convertible securities are bonds, debentures, notes, preferred stocks, or other
securities that may be converted into or exchanged for a specified amount of
common stock of the same or a different issuer within a particular period of
time at a specified price or formula. A convertible security entitles the holder
to receive interest normally paid or accrued on debt or the dividend paid on
preferred stock until the convertible security matures or is redeemed,
converted, or exchanged. Convertible securities have unique investment
characteristics in that they generally (i) have higher yields than common stocks
but lower yields than comparable non-convertible securities, (ii) are less
subject to fluctuation in value than the underlying stock since they have fixed
income characteristics, and (iii) provide the potential for capital appreciation
if the market price of the underlying common stock increases. Most convertible
securities currently are issued by U.S. companies, although a substantial
Eurodollar convertible securities market has developed, and the markets for
convertible securities denominated in local currencies are increasing.

         The value of a convertible security is a function of its "investment
value" (determined by its yield in comparison with the yields of other
securities of comparable maturity and quality that do not have a conversion
privilege) and its "conversion value" (the security's worth, at market value, if
converted into the underlying common stock). The investment value of a
convertible security is influenced by changes in interest rates, with investment
value declining as interest rates increase and increasing as interest rates
decline. The credit standing of the issuer and other factors also may have an
effect on the convertible security's



                                       10
<PAGE>   56

investment value. The conversion value of a convertible security is determined
by the market price of the underlying common stock. If the conversion value is
low relative to the investment value, the price of the convertible security is
governed principally by its investment value. Generally, the conversion value
decreases as the convertible security approaches maturity. To the extent the
market price of the underlying common stock approaches or exceeds the conversion
price, the price of the convertible security will be increasingly influenced by
its conversion value. A convertible security generally will sell at a premium
over its conversion value by the extent to which investors place value on the
right to acquire the underlying common stock while holding a fixed income
security.

         A convertible security may be subject to redemption at the option of
the issuer at a price established in the convertible security's governing
instrument. If a convertible security held by a Fund is called for redemption, a
Fund will be required to permit the issuer to redeem the security, convert it
into the underlying common stock, or sell it to a third party.

WARRANTS. The Mid Cap Growth Fund, Growth Fund, and Nationwide Fund may acquire
warrants. Warrants are securities giving the holder the right, but not the
obligation, to buy the stock of an issuer at a given price (generally higher
than the value of the stock at the time of issuance), on a specified date,
during a specified period, or perpetually. Warrants may be acquired separately
or in connection with the acquisition of securities.

         Warrants do not carry with them the right to dividends or voting rights
with respect to the securities that they entitle their holder to purchase, and
they do not represent any rights in the assets of the issuer. As a result,
warrants may be considered more speculative than certain other types of
investments. In addition, the value of a warrant does not necessarily change
with the value of the underlying securities, and a warrant ceases to have value
if it is not exercised prior to its expiration date.

RESTRICTED, NON-PUBLICLY TRADED AND ILLIQUID SECURITIES. Each Fund may not
invest more than 15% (10% for the Money Market Fund) of its net assets, in the
aggregate, in illiquid securities, including repurchase agreements which have a
maturity of longer than seven days, time deposits maturing in more than seven
days and securities that are illiquid because of the absence of a readily
available market or legal or contractual restrictions on resale. Repurchase
agreements subject to demand are deemed to have a maturity equal to the notice
period.

         Historically, illiquid securities have included securities subject to
contractual or legal restrictions on resale because they have not been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
securities which are otherwise not readily marketable and repurchase agreements
having a maturity of longer than seven days. Securities which have not been
registered under the Securities Act are referred to as private placements or
restricted securities and are purchased directly from the issuer or in the
secondary market. Investment companies do not typically hold a significant
amount of these restricted or other illiquid securities because of the potential
for delays on resale and uncertainty in valuation. Limitations on resale may
have an adverse effect on the marketability of portfolio securities, and a Fund
might be unable to dispose of restricted or other illiquid securities promptly
or at reasonable prices and might thereby experience difficulty satisfying
redemptions within seven days. A Fund might also have to register such
restricted securities in order to dispose of them resulting in additional
expense and delay. Adverse market conditions could impede such a public offering
of securities.


                                       11
<PAGE>   57


         In recent years, however, a large institutional market has developed
for certain securities that are not registered under the Securities Act
including foreign securities, municipal securities and corporate bonds and
notes. Institutional investors depend on an efficient institutional market in
which the unregistered security can be readily resold or on an issuer's ability
to honor a demand for repayment. The fact that there are contractual or legal
restrictions on resale to the general public or to certain institutions may not
be indicative of the liquidity of such investments.

         The SEC has adopted Rule 144A which allows for a broader institutional
trading market for securities otherwise subject to restriction on resale to the
general public. Rule 144A establishes a "safe harbor" from the registration
requirements of the Securities Act for resales of certain securities to
qualified institutional buyers. It is anticipated that the market for certain
restricted securities such as institutional commercial paper will expand further
as a result of this regulation and use of automated systems for the trading,
clearance and settlement of unregistered securities of domestic and foreign
issuers, such as the PORTAL System sponsored by the National Association of
Securities Dealers, Inc.

   
         Any such restricted securities will be considered to be illiquid for
purposes of such a Fund's limitations on investments in illiquid securities
unless, pursuant to procedures adopted by the Board of Trustees of the Trust or
NAS has determined such securities to be liquid because such securities are
eligible for resale pursuant to Rule 144A and are readily saleable.
    

         A Fund may buy or sell over-the-counter ("OTC") options and, in
connection therewith, segregate assets or cover its obligations with respect to
OTC options written by the Fund. The assets used as cover for OTC options
written by a Fund will be considered illiquid unless the OTC options are sold to
qualified dealers who agree that the Fund may repurchase any OTC option it
writes at a maximum price to be calculated by a formula set forth in the option
agreement. The cover for an OTC option written subject to this procedure would
be considered illiquid only to the extent that the maximum repurchase price
under the formula exceeds the intrinsic value of the option.

         NAS will monitor the liquidity of restricted securities in a Fund. In
reaching liquidity decisions, NAS may consider the following factors: (A) the
unregistered nature of the security; (B) the frequency of trades and quotes for
the security; (C) the number of dealers wishing to purchase or sell the security
and the number of other potential purchasers; (D) dealer undertakings to make a
market in the security and (E) the nature of the security and the nature of the
marketplace trades (e.g., the time needed to dispose of the security, the method
of soliciting offers and the mechanics of the transfer).

   
BORROWING. Each Fund may borrow money from banks, limited by the Fund's
fundamental investment restriction to 33-1/3% of its total assets (including the
amount borrowed), and may engage in mortgage dollar roll and reverse repurchase
agreements which may be considered a form of borrowing. In addition, a Fund may
borrow up to an additional 5% of its total assets from banks for temporary or
emergency purposes. The Money Market Fund will not purchase securities when bank
borrowings exceed 5% of such Fund's total assets.
    

         Each Fund expects that its borrowings will be on a secured basis. In
such situations, either the custodian will segregate the pledged assets for the
benefit of the lender or arrangements will be made with a suitable subcustodian,
which may


                                       12
<PAGE>   58

include the lender. The Funds have established a line-of-credit ("LOC") with
their custodian by which they may borrow for temporary or emergency purposes.
The Funds intend to use the LOC to meet large or unexpected redemptions that
would otherwise force a Fund to liquidate securities under circumstances which
are unfavorable to a Fund's remaining shareholders.

   
DERIVATIVE INSTRUMENTS. As discussed in the Prospectuses, NAS or a Subadviser
may use a variety of derivative instruments, including options, futures
contracts (sometimes referred to as "futures"), options on futures contracts,
stock index options and forward currency contracts to hedge a Fund's portfolio
or for risk management. Derivations are financial instruments whose value and
performance are based on the value and performance of another security,
financial instrument or index.
    

         The use of these instruments is subject to applicable regulations of
the SEC, the several options and futures exchanges upon which they may be
traded, and the Commodity Futures Trading Commission ("CFTC").

         Special Risks Of Derivative Instruments. The use of derivative
instruments involves special considerations and risks as described below. Risks
pertaining to particular instruments are described in the sections that follow.

         (1) Successful use of most of these instruments depends upon NAS's
ability to predict movements of the overall securities and currency markets,
which requires different skills than predicting changes in the prices of
individual securities. There can be no assurance that any particular strategy
adopted will succeed.

         (2) There might be imperfect correlation, or even no correlation,
between price movements of an instrument and price movements of investments
being hedged. For example, if the value of an instrument used in a short hedge
(such as writing a call option, buying a put option, or selling a futures
contract) increased by less than the decline in value of the hedged investment,
the hedge would not be fully successful. Such a lack of correlation might occur
due to factors unrelated to the value of the investments being hedged, such as
speculative or other pressures on the markets in which these instruments are
traded. The effectiveness of hedges using instruments on indices will depend on
the degree of correlation between price movements in the index and price
movements in the investments being hedged, as well as how similar the index is
to the portion of the Fund's assets being hedged in terms of securities
composition.

         (3) Hedging strategies, if successful, can reduce the risk of loss by
wholly or partially offsetting the negative effect of unfavorable price
movements in the investments being hedged. However, hedging strategies can also
reduce opportunity for gain by offsetting the positive effect of favorable price
movements in the hedged investments. For example, if a Fund entered into a short
hedge because NAS or the Subadviser projected a decline in the price of a
security in the Fund's portfolio, and the price of that security increased
instead, the gain from that increase might be wholly or partially offset by a
decline in the price of the instrument. Moreover, if the price of the instrument
declined by more than the increase in the price of the security, a Fund could
suffer a loss.

         (4) As described below, a Fund might be required to maintain assets as
"cover," maintain segregated accounts, or make margin payments when it takes
positions in these instruments involving obligations to third parties (i.e.,
instruments other than purchased options). If the Fund were unable to close out
its positions in such instruments, it might be required to continue to maintain
such


                                       13
<PAGE>   59

assets or accounts or make such payments until the position expired or matured.
The requirements might impair the Fund's ability to sell a portfolio security or
make an investment at a time when it would otherwise be favorable to do so, or
require that the Fund sell a portfolio security at a disadvantageous time. The
Fund's ability to close out a position in an instrument prior to expiration or
maturity depends on the existence of a liquid secondary market or, in the
absence of such a market, the ability and willingness of the other party to the
transaction ("counter party") to enter into a transaction closing out the
position. Therefore, there is no assurance that any hedging position can be
closed out at a time and price that is favorable to the Fund.

         For a discussion of the federal income tax treatment of a Fund's
derivative instruments, see "Additional General Tax Information" on page __.

   
         OPTIONS. Each of the Stock Funds may purchase or write put and call
options on securities and indices, and may purchase options on foreign
currencies, and enter into closing transactions with respect to such options to
terminate an existing position. A call option gives the purchaser the right to
buy, and the writer the obligation to sell, the underlying security at the
agreed upon exercise (or "strike") price during the option period. A put option
gives the purchaser the right to sell, and the writer the obligation to buy, the
underlying security at the strike price during the option period. Purchasers of
options pay an amount, known as a premium, to the option writer in exchange for
the right under the option contract. Option contracts may be written with terms
which would permit the holder of the option to purchase or sell the underlying
security only upon the expiration date of the option. The initial purchase
(sale) of an option contract is an "opening transaction". In order to close out
an option position, a Fund may enter into a "closing transaction", 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. The purchase
of call options serves as a long hedge, and the purchase of put options serves
as a short hedge. Writing put or call options can enable a Fund to enhance
income by reason of the premiums paid by the purchaser of such options. Writing
call options serves as a limited short hedge because declines in the value of
the hedged investment would be offset to the extent of the premium received for
writing the option. However, if the security appreciates to a price higher than
the exercise price of the call option, it can be expected that the option will
be exercised, and the Fund will be obligated to sell the security at less than
its market value or will be obligated to purchase the security at a price
greater than that at which the security must be sold under the option. All or a
portion of any assets used as cover for OTC options written by a Fund would be
considered illiquid to the extent described under "Restricted and Illiquid
Securities" above. Writing put options serves as a limited long hedge because
increases in the value of the hedged investment would be offset to the extent of
the premium received for writing the option. However, if the security
depreciates to a price lower than the exercise price of the put option, it can
be expected that the put option will be exercised, and the Fund will be
obligated to purchase the security at more than its market value.
    

         The value of an option position will reflect, among other things, the
historical price volatility of the underlying investment, the current market
value of the underlying investment, the time remaining until expiration of the
option, the relationship of the exercise price to the market price of the
underlying investment, and general market conditions. Options that expire
unexercised have no value. Options used by the Fund may include European-style
options, which can only be exercised at expiration. This is in contrast to
American-style options which can be exercised at any time prior to the
expiration date of the option.


                                       14
<PAGE>   60

         A Fund may effectively terminate its right or obligation under an
option by entering into a closing transaction. For example, a Fund may terminate
its obligation under a call or put option that it had written by purchasing an
identical call or put option; this is known as a closing purchase transaction.
Conversely, a Fund may terminate a position in a put or call option it had
purchased by writing an identical put or call option; this is known as a closing
sale transaction. Closing transactions permit the Fund to realize the profit or
limit the loss on an option position prior to its exercise or expiration.

         A Fund may purchase or write both OTC options and options traded on
foreign and U.S. exchanges. Exchange-traded options are issued by a clearing
organization affiliated with the exchange on which the option is listed that, in
effect, guarantees completion of every exchange-traded option transaction. OTC
options are contracts between the Fund and the counterparty (usually a
securities dealer or a bank) with no clearing organization guarantee. Thus, when
the Fund purchases or writes an OTC option, it relies on the counter party to
make or take delivery of the underlying investment upon exercise of the option.
Failure by the counter party to do so would result in the loss of any premium
paid by the fund as well as the loss of any expected benefit of the transaction.

         Each Stock Fund's ability to establish and close out positions in
exchange-listed options depends on the existence of a liquid market. Each of the
Stock Funds intends to purchase or write only those exchange-traded options for
which there appears to be a liquid secondary market. However, there can be no
assurance that such a market will exist at any particular time. Closing
transactions can be made for OTC options only by negotiating directly with the
counterparty, or by a transaction in the secondary market if any such market
exists. Although a Fund will enter into OTC options only with counterparties
that are expected to be capable of entering into closing transactions with a
Fund, there is no assurance that such Fund will in fact be able to close out an
OTC option at a favorable price prior to expiration. In the event of insolvency
of the counter party, a Fund might be unable to close out an OTC option position
at any time prior to its expiration.

         If a Fund is unable to effect a closing transaction for an option it
had purchased, it would have to exercise the option to realize any profit. The
inability to enter into a closing purchase transaction for a covered call option
written by a Fund could cause material losses because the Fund would be unable
to sell the investment used as a cover for the written option until the option
expires or is exercised.

         Each Stock Fund may engage in options transactions on indices in much
the same manner as the options on securities discussed above, except that index
options may serve as a hedge against overall fluctuations in the securities
markets in general. Unlike options on securities, index options settle in cash.

         The writing and purchasing of options is a highly specialized activity
that involves investment techniques and risks different from those associated
with ordinary portfolio securities transactions. Imperfect correlation between
the options and securities markets may detract from the effectiveness of
attempted hedging.

         Transactions using OTC options (other than purchased options) expose a
Fund to counter party risk. To the extent required by SEC guidelines, a Fund
will not enter into any such transactions unless it owns either (1) an
offsetting ("covered") position in securities, other options, or futures or (2)
cash and liquid obligations with a value sufficient at all times to cover its
potential obligations to the


                                       15
<PAGE>   61

extent not covered as provided in (1) above. A Fund will also set aside cash
and/or appropriate liquid assets in a segregated custodial account if required
to do so by the SEC and CFTC regulations. Assets used as cover or held in a
segregated account cannot be sold while the position in the corresponding option
or futures contract is open, unless they are replaced with similar assets. As a
result, the commitment of a large portion of the Fund's assets to segregated
accounts as a cover could impede portfolio management or the Fund's ability to
meet redemption requests or other current obligations.

   
         PUTS. The Tax-Free Income Fund may also acquire "puts" with respect to
municipal securities held in its portfolio. A put is a right to sell a specified
security (or securities) within a specified period of time at a specified
exercise price. The Tax-Free Income Fund may sell, transfer, or assign a put
only in conjunction with the sale, transfer, or assignment of the underlying
security or securities.

         The amount payable to the Tax-Free Income Fund upon its exercise of a
"put" is normally (i) the Tax-Free Income Fund's acquisition cost of the
municipal securities (excluding any accrued interest which the Tax-Free Income
Fund paid on the acquisition), less any amortized market premium or plus any
amortized market or original issue discount during the period the Tax-Free
Income Fund owned the securities, plus (ii) all interest accrued on the
securities since the last interest payment date during that period.

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

         The Tax-Free Income Fund expects that it will generally acquire puts
only where the puts are available without the payment of any direct or indirect
consideration. However, if necessary or advisable, the Tax-Free Income Fund may
pay for puts either separately in cash or by paying a higher price for portfolio
securities which are acquired subject to the puts (thus reducing the yield to
maturity otherwise available for the same securities).

         The Tax-Free Income Fund intends to enter into puts only with dealers,
banks, and broker-dealers which, in NAS's opinion, present minimal credit risks.
    

         FUTURES CONTRACTS. The Stock Funds may enter into futures contracts,
including interest rate, index, and currency futures and purchase and write
(sell) related options. The purchase of futures or call options thereon can
serve as a long hedge, and the sale of futures or the purchase of put options
thereon can serve as a short hedge. Writing covered call options on futures
contracts can serve as a limited short hedge, and writing covered put options on
futures contracts can serve as a limited long hedge, using a strategy similar to
that used for writing covered options in securities. A Fund's hedging may
include purchases of futures as an offset against the effect of expected
increases in securities prices or currency exchange rates and sales of futures
as an offset against the effect of expected declines in securities prices or
currency exchange rates. A Fund may write put options on futures contracts while
at the same time purchasing call options on the same futures contracts in order
to create synthetically a long futures contract position. Such options would
have the same strike prices and expiration dates. A Fund will engage in this
strategy only when NAS or a Subadviser believes it is more advantageous to a
Fund than is purchasing the futures contract.


                                       16
<PAGE>   62

         To the extent required by regulatory authorities, a Fund will only
enter into futures contracts that are traded on U.S. or foreign exchanges or
boards of trade approved by the CFTC and are standardized as to maturity date
and underlying financial instrument. These transactions may be entered into for
"bona fide hedging" purposes as defined in CFTC regulations and other
permissible purposes including increasing return and hedging against changes in
the value of portfolio securities due to anticipated changes in interest rates,
currency values and/or market conditions. The ability of a Fund to trade in
futures contracts may be limited by the requirements of the Code applicable to a
regulated investment company.

         A Fund will not enter into futures contracts and related options for
other than "bona fide hedging" purposes for which the aggregate initial margin
and premiums required to establish positions exceed 5% of the Fund's net asset
value after taking into account unrealized profits and unrealized losses on any
such contracts it has entered into. There is no overall limit on the percentage
of a Fund's assets that may be at risk with respect to futures activities.
Although techniques other than sales and purchases of futures contracts could be
used to reduce a Fund's exposure to market, currency, or interest rate
fluctuations, such Fund may be able to hedge its exposure more effectively and
perhaps at a lower cost through using futures contracts.

         A futures contract provides for the future sale by one party and
purchase by another party of a specified amount of a specific financial
instrument (e.g., debt security) or currency for a specified price at a
designated date, time, and place. An index futures contract is an agreement
pursuant to which the parties agree to take or make delivery of an amount of
cash equal to a specified multiplier times the difference between the value of
the index at the close of the last trading day of the contract and the price at
which the index futures contract was originally written. Transactions costs are
incurred when a futures contract is bought or sold and margin deposits must be
maintained. A futures contract may be satisfied by delivery or purchase, as the
case may be, of the instrument, the currency, or by payment of the change in the
cash value of the index. More commonly, futures contracts are closed out prior
to delivery by entering into an offsetting transaction in a matching futures
contract. Although the value of an index might be a function of the value of
certain specified securities, no physical delivery of those securities is made.
If the offsetting purchase price is less than the original sale price, a Fund
realizes a gain; if it is more, a Fund realizes a loss. Conversely, if the
offsetting sale price is more than the original purchase price, a Fund realizes
a gain; if it is less, a Fund realizes a loss. The transaction costs must also
be included in these calculations. There can be no assurance, however, that a
Fund will be able to enter into an offsetting transaction with respect to a
particular futures contract at a particular time. If a Fund is not able to enter
into an offsetting transaction, that Fund will continue to be required to
maintain the margin deposits on the futures contract.

         No price is paid by a Fund upon entering into a futures contract.
Instead, at the inception of a futures contract, the Fund is required to deposit
in a segregated account with its custodian, in the name of the futures broker
through whom the transaction was effected, "initial margin" consisting of cash,
U.S. Government securities or other liquid obligations, in an amount generally
equal to 10% or less of the contract value. Margin must also be deposited when
writing a call or put option on a futures contract, in accordance with
applicable exchange rules. Unlike margin in securities transactions, initial
margin on futures contracts does not represent a borrowing, but rather is in the
nature of a performance bond or good-faith deposit that is returned to a Fund at
the termination of the transaction if all contractual obligations have been
satisfied. Under certain circumstances,


                                       17
<PAGE>   63

such as periods of high volatility, a Fund may be required by an exchange to
increase the level of its initial margin payment, and initial margin
requirements might be increased generally in the future by regulatory action.

         Subsequent "variation margin" payments are made to and from the futures
broker daily as the value of the futures position varies, a process known as
"marking to market." Variation margin does not involve borrowing, but rather
represents a daily settlement of a Fund's obligations to or from a futures
broker. When a Fund purchases an option on a future, the premium paid plus
transaction costs is all that is at risk. In contrast, when a Fund purchases or
sells a futures contract or writes a call or put option thereon, it is subject
to daily variation margin calls that could be substantial in the event of
adverse price movements. If a Fund has insufficient cash to meet daily variation
margin requirements, it might need to sell securities at a time when such sales
are disadvantageous. Purchasers and sellers of futures positions and options on
futures can enter into offsetting closing transactions by selling or purchasing,
respectively, an instrument identical to the instrument held or written.
Positions in futures and options on futures may be closed only on an exchange or
board of trade on which they were entered into (or through a linked exchange).
Although the Funds intend to enter into futures transactions only on exchanges
or boards of trade where there appears to be an active market, there can be no
assurance that such a market will exist for a particular contract at a
particular time.

         Under certain circumstances, futures exchanges may establish daily
limits on the amount that the price of a future or option on a futures contract
can vary from the previous day's settlement price; once that limit is reached,
no trades may be made that day at a price beyond the limit. Daily price limits
do not limit potential losses because prices could move to the daily limit for
several consecutive days with little or no trading, thereby preventing
liquidation of unfavorable positions.

         If a Fund were unable to liquidate a futures or option on a futures
contract position due to the absence of a liquid secondary market or the
imposition of price limits, it could incur substantial losses, because it would
continue to be subject to market risk with respect to the position. In addition,
except in the case of purchased options, the Fund would continue to be required
to make daily variation margin payments and might be required to maintain the
position being hedged by the future or option or to maintain cash or securities
in a segregated account.

         Certain characteristics of the futures market might increase the risk
that movements in the prices of futures contracts or options on futures
contracts might not correlate perfectly with movements in the prices of the
investments being hedged. For example, all participants in the futures and
options on futures contracts markets are subject to daily variation margin calls
and might be compelled to liquidate futures or options on futures contracts
positions whose prices are moving unfavorably to avoid being subject to further
calls. These liquidations could increase price volatility of the instruments and
distort the normal price relationship between the futures or options and the
investments being hedged. Also, because initial margin deposit requirements in
the futures markets are less onerous than margin requirements in the securities
markets, there might be increased participation by speculators in the future
markets. This participation also might cause temporary price distortions. In
addition, activities of large traders in both the futures and securities markets
involving arbitrage, "program trading" and other investment strategies might
result in temporary price distortions.

FORWARD CURRENCY CONTRACTS. The Mid Cap Growth Fund, Growth Fund and Nationwide
Fund may enter into forward currency contracts. A forward currency contract
involves an obligation to purchase or sell a specific currency at a future date,
which may be any fixed number of days from the date of the contract agreed upon
by the parties, at a price set at the time of the contract. These contracts are
entered into in the interbank market conducted directly between currency traders
(usually large commercial banks) and their customers.

         At or before the maturity of a forward contract, a Fund may either sell
a portfolio security and make delivery of the currency, or retain the security
and fully or partially offset its contractual obligation to deliver the currency
by purchasing a second contract. If a Fund retains the portfolio security and
engages in an offsetting transaction, the Fund, at the time of execution of the
offsetting transaction, will incur a gain or a loss to the extent that movement
has occurred in forward contract prices.

         The precise matching of forward currency contract amounts and the value
of the securities involved generally will not be possible because the value of
such securities, measured in the foreign currency, will change after the foreign
currency contract has been established. Thus, the Fund might need to purchase or
sell foreign currencies in the spot (cash) market to the extent such foreign
currencies are not covered by forward contracts. The projection of short-term
currency market movements is extremely difficult, and the successful execution
of a short-term hedging strategy is highly uncertain.

SECURITIES OF OTHER NON-AFFILIATED INVESTMENT COMPANIES. Some of the countries
in which a Fund may invest may not permit direct investment by outside
investors. Investments in such countries may only be permitted through foreign
government-approved or government-authorized investment vehicles, which may
include other investment companies. The Funds may also invest in shares of other
non-affiliated investment companies registered under the 1940 Act. Investing
through such vehicles may involve frequent or layered fees or expenses and may
also be subject to limitation under the 1940 Act. Under the 1940 Act, a Fund may
invest up to 10% of its assets in shares of investment companies and up to 5% of
its assets in any one investment company as long as the investment does not
represent more than 3% of the voting stock of the acquired investment company.

BANK OBLIGATIONS. As stated in a Fund's Prospectus, bank obligations that may be
purchased by a Fund include certificates of deposit, banker's acceptances and
fixed time deposits. A certificate of deposit is a short-term negotiable
certificate issued by a commercial bank against funds deposited in the bank and
is either interest-bearing or purchased on a discount basis. A bankers'
acceptance is a short-term draft drawn on a commercial bank by a borrower,
usually in connection with an international commercial transaction. The borrower
is liable for payment as is the bank, which unconditionally guarantees to pay
the draft at its face amount on the maturity date. Fixed time deposits are
obligations of branches of U.S. banks or foreign banks which are payable at a
stated maturity date and bear a fixed rate of interest. Although fixed time
deposits do not have a market, there are no contractual restrictions on the
right to transfer a beneficial interest in the deposit to a third party.

         Bank obligations may be general obligations of the parent bank or may
be limited to the issuing branch by the terms of the specific obligations or by
government regulation.

FLOATING AND VARIABLE RATE INSTRUMENTS. The Nationwide Bond, Tax-Free Income and
Money Market Fund may invest in floating and variable rate instruments. Certain
of the floating or variable rate obligations that may be purchased by these
Funds may carry a demand feature that would permit the holder to tender them
back to the issuer of the instrument or to a third party at par value prior to
maturity. Some of the demand instruments purchased by a Fund are not traded in a
secondary market and derive their liquidity solely from the ability of the
holder to demand repayment from the issuer or third party providing credit
support. If a demand instrument is not traded in a secondary market, the Fund
will nonetheless treat the instrument as "readily marketable" for the purposes
of its investment restriction limiting investments in illiquid securities unless
the demand feature has a notice period of more than seven days in which case the
instrument will be characterized as "not readily marketable" and therefore
illiquid.

         The Fund's right to obtain payment at par on a demand instrument could
be affected by events occurring between the date the Fund elects to demand
payment and the date payment is due that may affect the ability of the issuer of
the instrument or third party providing credit support to make payment when due,
except when such demand instruments permit same day settlement. To facilitate
settlement, these same day demand instruments may be held in book entry form at
a bank other than a Fund's custodian subject to a subcustodian agreement
approved by the Fund between that bank and the Fund's custodian.

ZERO COUPON SECURITIES. The Bond Funds may invest in zero coupon securities in
accordance with investment policies described in the Prospectus.

         Zero coupon securities are debt securities that pay no cash income but
are sold at substantial discounts from their value at maturity. When a zero
coupon security is held to maturity, its entire return, which consists of the
amortization of discount, comes from the difference between its purchase price
and its maturity value. This difference is known at the time of purchase, so
that investors holding zero coupon securities until maturity know at the time of
their investment what the expected return on their investment will be. Zero
coupon securities may have conversion features.

         Zero coupon securities tend to be subject to greater price fluctuations
in response to changes in interest rates than are ordinary interest-paying debt
securities with similar maturities. The value of zero coupon securities
appreciates more during periods of declining interest rates and depreciates more
during periods of rising interest rates than ordinary interest-paying debt
securities with similar maturities. Zero coupon securities may be issued by a
wide variety of corporate and governmental issuers. Although these instruments
are generally not traded on a national securities exchange, they are widely
traded by brokers and dealers and, to such extent, will not be considered
illiquid for the purposes of the Fund's limitation on investments in illiquid
securities.

         Current federal income tax law requires the holder of a zero coupon
security acquired at a discount to accrue income with respect to these
securities prior to the receipt of cash payments. Accordingly, to avoid
liability for federal income and excise taxes, the Fund may be required to
distribute income accrued with respect to these securities and may have to
dispose of portfolio securities under disadvantageous circumstances in order to
generate cash to satisfy these distribution requirements.

INVESTMENT RESTRICTIONS

The following are fundamental investment restrictions of each Fund which cannot
be changed without the authorization of the majority of the outstanding shares
of the Fund for which a change is proposed.

EACH OF THE FUNDS:

   
     -    May not purchase securities of any one issuer, other than obligations
          issued or guaranteed by the U.S. Government, its agencies or
          instrumentalities, if, immediately after such purchase, more than 5%
          of the Fund's total assets would be invested in such issuer or the
          Fund would hold more than 10% of the outstanding voting securities of
          the issuer, except that 25% or less of the Fund's total assets may be
          invested without regard to such limitations. There is no limit to the
          percentage of assets that may be invested in U.S. Treasury bills,
          notes, or other obligations issued or guaranteed by the U.S.
          Government, its agencies or instrumentalities. The Money Market Fund
          will be deemed to be in compliance with this restriction so long as it
          is in compliance with Rule 2a-7 under the 1940 Act, as such Rule may
          be amended from time to time.
    

     -    May (i) borrow money from banks and (ii) make other investments - or
          engage in other transactions permissible under the Investment Company
          Act of 1940 (the "1940 Act") which may involve a borrowing, provided
          that the combination of (i) and (ii) shall not exceed 33-1/3% of the
          value of the Fund's total assets (including the amount borrowed), less
          the Fund's liabilities (other than borrowings), except that the Fund
          may borrow up to an additional 5% of its total assets (not including
          the amount borrowed) from a bank for temporary or emergency purposes
          (but not for leverage or the purchase of investments). The Fund may
          also borrow money from other persons to the extent permitted by
          applicable law. For purposes of this restriction, short sales, the
          entry into currency transactions, options, futures contracts, options
          on futures contracts, forward commitment transactions and dollar roll
          transactions that are not accounted for as financings (and the
          segregation of assets in connection with any of the foregoing) shall
          not constitute borrowing.

     -    May not issue senior securities, except as permitted under the 1940
          Act.

     -    May not act as an underwriter of another issuer's securities, except
          to the extent that the Fund may be deemed an underwriter within the
          meaning of the Securities Act in connection with the purchase and sale
          of portfolio securities.

     -    May not purchase or sell real estate unless acquired as a result of
          ownership of securities or instruments, but this restriction shall not
          prohibit the Fund from purchasing or selling securities issued by
          entities or investment vehicles that own or deal in real estate or
          interests therein or instruments secured by real estate or interests
          therein.

     -    May not purchase or sell commodities or commodities contracts, except
          to the extent disclosed in the current Prospectus of such Fund.

     -    May not lend any security or make any other loan if, as a result, more
          than 33 1/3% of its total assets (taken at current value) would be
          lent to other parties, except in accordance with its investment
          objective, policies and limitations through (i) purchase of debt
          securities or other debt instruments, 


                                       21
<PAGE>   67

          including loan participations, assignments and structured securities,
          or (ii) by engaging in repurchase agreements.

   
     -    May not purchase the securities of any issuer if, as a result, more
          than 25% (taken at current value) of the Fund's total assets would be
          invested in the securities of issuers, the principal activities of
          which are in the same industry. Captive borrowing conduit, equipment
          finance, premium finance, leasing finance, consumer sales finance and
          other finance are considered separate industries for purposes of this
          restriction. Electric, natural gas distribution, natural gas pipeline,
          combined electric and natural gas, and telephone utilities are
          considered separate industries for purposes of this restriction. This
          limitation does not apply to securities issued by the U.S. Government
          or its agencies or instrumentalities and obligations issued by state,
          county or municipal governments.
    

The following are the non-fundamental operating policies of the Funds which may
be changed by the Board of Trustees of the Trust without shareholder approval:

Each Fund may not:

     -    Sell securities short, unless the Fund owns or has the right to obtain
          securities equivalent in kind and amount to the securities sold short
          or unless it covers such short sales as required by the current rules
          and positions of the SEC or its staff, and provided that short
          positions in forward currency contracts, options, futures contracts,
          options on futures contracts, or other derivative instruments are not
          deemed to constitute selling securities short.

     -    Purchase securities on margin, except that the Fund may obtain such
          short-term credits as are necessary for the clearance of transactions;
          and provided that margin deposits in connection with options, futures
          contracts, options on futures contracts, transactions in currencies or
          other derivative instruments shall not constitute purchasing
          securities on margin.

   
     -    Purchase or otherwise acquire any security if, as a result, more than
          15% (10% with respect to the Money Market Fund) of its net assets
          would be invested in securities that are illiquid.
    

     -    Purchase securities of other investment companies except in connection
          with a merger, consolidation, acquisition, reorganization or offer of
          exchange, or as otherwise permitted under the 1940 Act.

     -    Pledge, mortgage or hypothecate any assets owned by the Fund in excess
          of 33 1/3% of the Fund's total assets at the time of such pledging,
          mortgaging or hypothecating.

INVESTMENT ADVISORY AND OTHER SERVICES

Under the terms of the Investment Management Agreement dated _________1997,
Nationwide Advisory Services, Inc. ("NAS") manages the investment of the assets
of the Funds in accordance with the policies and procedures established by the
Trustees.

servicing the investments of the Trust and maintaining its investment advisory
facilities, and executive and supervisory personnel for managing the investments
and effecting the portfolio transactions of the Trust.

The Investment Advisory Agreement also specifically provides that the Adviser,

ADVISORY SERVICES FOR THE S&P 500 INDEX FUND

Under the terms of the Investment Advisory Agreement, NAS oversees the
investment of the assets for the S&P 500 Index Fund. Subject to the supervision
and direction of the Trustees, the Adviser also evaluates and monitors the
performance of the subadviser. The Adviser is also authorized to select and
place portfolio investments on behalf of the Fund, however the Adviser does not
intend to do so at this time.

The Adviser provides to the Fund investment management evaluation services
principally by performing initial due diligence on prospective Subadvisers for
the Fund and thereafter monitoring the performance of the Subadviser through
quantitative and qualitative analysis as well as periodic in-person, telephonic
and written consultations with the Subadviser. The Adviser has responsibility
for communicating performance expectations and evaluations to the Subadviser and
ultimately recommending to the Trust's Board of Trustees whether the
Subadviser's contract should be renewed, modified or terminated; however, the
Adviser does not expect to recommend frequent changes of subadvisers. The
Adviser will regularly provide written reports to the Board of Trustees
regarding the results of its evaluation and monitoring functions. Although the
Adviser will monitor the performance of the Subadviser, there is no certainty
that the Subadviser or the Fund will obtain favorable results at any given time.

The S&P 500 Index Fund pays the Adviser a fee at the annual rate of .13% of the
Fund's average daily net assets for investment advisory services.

The Adviser may from time to time waive some or all of its investment advisory
fee or other fees. The waiver of such fees will cause the total return and yield
of the Fund to be higher than they would otherwise be in the absence of such a
waiver.

   
The Subadviser - Subject to the supervision of the Adviser and the Board of
Trustees, The Dreyfus Corporation manages the S&P 500 Index Fund's assets in
accordance with such Fund's investment objective and policies. The Subadviser
shall make investment decisions for the S&P 500 Index Fund, and in connection
with such investment 


                                       26
<PAGE>   72

decisions shall place purchase and sell orders for securities. For the
investment management services it provides to the Fund, the Subadviser receives
an annual fee from the Adviser in the following amounts:

     .07% on assets up to $250 million 
     .06% on assets of $250 million up to $500 million 
     .05% on assets of $500 million up to $1 billion 
     .04% on assets of $1 billion and more.

Below is a brief description of the Subadviser.

The Dreyfus Corporation ("Dreyfus"), 200 Park Avenue, New York, N.Y. 10166, was
formed in 1947 and registered under the Investment Advisers Act of 1940, serves
as subadviser to the Fund pursuant to a Subadvisory Agreement
dated_____________. Dreyfus is a wholly-owned subsidiary of Mellon Bank, N.A.,
which is a wholly-owned subsidiary of Mellon Bank Corporation.
    

DISTRIBUTION PLAN FOR THE S&P 500 INDEX FUND

   
The S&P 500 Index Fund has adopted a Distribution Plan (the "Plan") under Rule
12b-1 of the Investment Company Act of 1940 which permits the Fund to compensate
NAS as such Fund's Distributor, for expenses associated with distribution of its
shares. Under the Plan, the S&P 500 Index Fund pays NAS compensation accrued
daily and paid monthly at a maximum rate of .07% of the Fund's average daily net
assets. Distribution expenses paid by NAS may include the costs of marketing,
printing and mailing prospectuses and sales literature to prospective investors,
advertising, and compensation to sales personnel and broker-dealers.
    

   
OTHER SERVICES FOR ALL THE FUNDS

Under a separate Fund Administration Agreement dated ____________ 1997, NAS also
provides various administrative and accounting services, including daily
valuation of each Fund's shares and preparation of financial statements, tax
returns and regulatory reports. For these services, each Fund (except the S&P
500 Index Fund) pays NAS an annual fee in the amount of 0.07% on assets up to
$250 million of average daily net assets, 0.05% on the next $750 million and
0.04% on assets of $1 billion and more. The S&P 500 Index Fund pays NAS an
annual fee in the amount of 0.05% on assets up to $1 billion and 0.04% on assets
of $1 billion and more. The S&P 500 Index Fund pays NAS an annual fee in the
amount of 0.05% on assets up to $1 billion and 0.04% on assets of $1 billion
and more.

Nationwide Investors Services, Inc. (NIS) is the Transfer and Dividend
Disbursing Agent for all Nationwide Funds. NIS, a wholly-owned subsidiary of NAS
will receive fees for transfer agent services in the following amounts: $16 per
Stock Fund account in Class D shares per annum; $18 per Bond Fund account in
Class D shares per annum; $27 per Money Market Fund account per annum and
 .01% annually of average daily net assets of the S&P 500 Index Fund. Management
believes the charges for the services performed are comparable to fees charged
by other companies performing similar services.

The Fifth Third Bank ("Fifth Third"), 38 Fountain Square Plaza, Cincinnati, OH
45263, is the custodian for the Funds and makes all receipts and disbursements
under a Mutual Fund Custody Agreement. Fifth Third performs no managerial or
policy-making functions for the Funds.

BROKERAGE ALLOCATION

ALLOCATION OF PORTFOLIO BROKERAGE--There is no commitment by NAS to place
orders with any particular broker/dealer or group of broker/dealers. Orders for
the purchases and sales of portfolio securities of the Funds are placed where,
in the judgment of NAS or the Subadviser, the best executions can be obtained.
None of the firms with whom orders are placed are engaged in the sale of shares
of the Funds. In allocating orders among brokers for execution on an agency
basis, in addition to price considerations, the usefulness of the brokers'
overall services is also considered. Services provided by brokerage firms
include efficient handling of 
    


                                       27
<PAGE>   73


orders, useful analyses of corporations, industries and the economy, statistical
reports and other related services for which no charge is made by the broker
above the negotiated brokerage commissions. The Funds and NAS believe that these
services and information, which in many cases would be otherwise unavailable to
the Investment Manager, are of significant value to the Investment Manager, but
it is not possible to place an exact dollar value thereon. The Investment
Manager does not believe that the receipt of such services and information tends
to reduce materially the Investment Manager's expense.

   
In the case of securities traded in the over-the-counter market, the Funds will
normally deal with the market makers for such securities unless better prices
can be obtained through brokers.
    

CALCULATION OF NET ASSET VALUE OF THE
MONEY MARKET FUND

         The Nationwide Money Market Fund's net asset value per share is
calculated by adding the value of all securities and other assets of the Fund,
deducting its liabilities, and dividing by the number of shares outstanding.

         The value of portfolio securities is determined on the basis of the
amortized cost, method of valuation in accordance with Rule 2a-7 of the 1940
Act. This involves valuing a security at its cost and thereafter assuming a
constant amortization to maturity of any discount or premium, regardless of the
impact of fluctuating interest rates on the market value of the instrument.
While this method provides certainty in valuation, it may result in periods
during which value, as determined by amortized cost, is higher or lower than the
price the Fund would receive if it sold the instrument.

         The Trustees have adopted procedures whereby the extent of deviation,
if any, of the current net asset value per share calculated using available
market quotations from the Money Market Fund's amortized cost price per share,
will be determined at such intervals as the Trustees deem appropriate and are
reasonable in light of current market conditions. In the event such deviation
from the Money Market Fund's amortized cost price per share exceeds 1/2 of 1
percent, the Trustees will consider appropriate action which might include a
revaluation of all or an appropriate portion of the Money Market Fund's assets
based upon current market factors.

         The Trustees, in supervising the Fund's operations and delegating
special responsibilities involving portfolio management to NAS, have undertaken
as a particular responsibility within their overall duty of care owed to the
Fund's shareholders to assure to the extent reasonably practicable, taking into
account current market conditions affecting the Fund's investment objectives,
that the Fund's net asset value per share, rounded to the nearest one cent, will
not deviate from $1.

         Pursuant to its objective of maintaining a stable net asset value per
share, the Money Market Fund will only purchase investments with a remaining
maturity of 397 days or less and will maintain a dollar weighted average
portfolio maturity of 90 days or less.

CALCULATING MONEY MARKET FUND YIELD

   
Any current Fund yield quotations, subject to Rule 482 under the Securities Act
of 1933, shall consist of a seven calendar day historical yield, carried at
least to the nearest hundredth of a percent. The yield shall be calculated by
determining the change, excluding realized and unrealized gains and losses, in
the value of a 
    

                                       28
<PAGE>   74
   
hypothetical pre-existing account having a balance of one share at the beginning
of the period, dividing the net change in account value by the value of the
account at the beginning of the base period to obtain the base period return,
and multiplying the base period return by 365/7 (or 366/7 during a leap year).
For purposes of this calculation , the net change in account value reflects the
value of additional shares purchased with dividends declared on both the
original share and any such additional shares. The Fund's effective yield
represents an annualization of the current seven day return with all dividends
reinvested.
    
   
         The Money Market Fund's yield will fluctuate daily. Actual yields will
depend on factors such as the type of instruments in the Money Market Fund's
portfolio, portfolio quality and average maturity, changes in interest rates,
and the Money Market Fund's expenses.

         Although the Fund determines its yield on the basis of a seven calendar
day period, it may use a different time span on occasion.

         There is no assurance that the yields quoted on any given occasion will
remain in effect for any period of time and there is no guarantee that the net
asset values will remain constant. It should be noted that a shareholder's
investment in the Fund is not guaranteed or insured. Yields of other money
market funds may not be comparable if a different base period or another method
of calculation is used.

CALCULATING YIELD AND TOTAL RETURN--
NON-MONEY MARKET FUNDS

The Funds may from time to time advertise historical performance, subject to
Rule 482 under the Securities Act of 1933. An investor should keep in mind that
any return or yield quoted represents past performance and is not a guarantee of
future results. The investment return and principal value of investments will
fluctuate so that an investor's shares, when redeemed, may be worth more or less
than their original cost. All performance advertisements shall include average
annual (compound) total return quotations for the most recent one, five, and
ten-year periods (or life if a Fund has been in operation less than one of the
prescribed periods). Average annual (compound) total return represents
redeemable value at the end of the quoted period. It is calculated in a uniform
manner by dividing the ending redeemable value of a hypothetical initial payment
of $1,000 minus the maximum sales charge, for a specified period of time, by the
amount of the initial payment, assuming reinvestment of all dividends and
distributions. The one, five, and ten-year periods are calculated based on
periods that end on the last day of the calendar quarter preceding the date on
which an advertisement is submitted for publication.


NONSTANDARD RETURNS

The Funds may also choose to show nonstandard returns including total return,
and simple average total return. Nonstandard returns may or may not reflect
reinvestment of all dividends and capital gains; in addition, sales charge
assumptions will vary. Sales charge percentages decrease as amounts invested
increase as outlined in the prospectus; therefore, returns increase as sales
charges decrease.

Total return represents the cumulative percentage change in the value of an
investment over time, calculated by subtracting the initial investment from the
redeemable value and dividing the result by the amount of the initial
investment. The simple average total return is calculated by dividing total
return by the number of 
    


                                       29
<PAGE>   75

years in the period, and unlike average annual (compound) total return, does not
reflect compounding.

The Nationwide Bond Fund, Nationwide Tax-Free Income Fund, Nationwide
Intermediate U.S. Government Bond Fund and Nationwide Long-Term U.S. Government
Bond Fund may also from time to time advertise a uniformly calculated yield
quotation. This yield is calculated by dividing the net investment income per
share earned during a 30-day base period by the maximum offering price per share
on the last day of the period, assuming reinvestment of all dividends and
distributions. This yield formula uses the average number of shares entitled to
receive dividends, provides for semi-annual compounding of interest, and
includes a modified market value method for determining amortization. The yield
will fluctuate, and there is no assurance that the yield quoted on any given
occasion will remain in effect for any period of time.

ADDITIONAL INFORMATION

DESCRIPTION OF SHARES--The assets of each Fund are segregated and a shareholder
has an interest in only the assets of the Fund in which he owns shares. Shares
of a particular Fund are equal in all respects to the other shares of that class
and in the event of liquidation of a Fund will share pro rata in the
distribution of the net assets of such Fund. All shares are without par value
and fully paid, nonassessable, transferable and redeemable. There are no
pre-emptive rights.

   
VOTING RIGHTS--Shareholders of each class of shares have one vote for each share
held. Voting rights cover the Investment Management Agreement, election of
Trustees, termination or reorganization of the Trust or any Series or Class,
merger, consolidation or sale of assets as a whole, change of investment
objectives, investment policies, investment restrictions, amendment of the
Declaration of Trust, and to the same extent as shareholders of an Ohio business
corporation as to whether or not court action, proceeding or claim should or
should not be brought or maintained and other business matters. In regard to
termination, sale of assets, or change of investment objectives, policies and
restrictions, the right to vote is limited to the holders of shares of the
particular class affected by the proposal.

               Except as otherwise provided in the Declaration or as required by
the 1940 Act or other applicable law, matters voted on by Shareholders must be
approved by the affirmative vote of the holders of a majority of the Shares
voting at any meeting of Shareholders and Trustees must be elected by a
plurality of the Shares voting, or by an instrument in writing, without a
meeting, signed by a majority of the Trustees and consented to by the holders of
a majority of Shares outstanding and entitled to vote, or by such other vote as
may be established by the Trustees with respect to any Series or Class of
Shares, provided that the election of Trustees (after the election by the
initial Shareholder) must be approved by the Shareholders at a meeting of
Shareholders.

               Each whole Share shall be entitled to one vote as to any matter
on which it is entitled to vote and each fractional Share shall be entitled to
proportionate fractional vote, except that Shares held in the treasury of the
Trust shall not be voted, that on matter relating to the Trust and governed by
the 1940 Act shall be voted in accordance with the 1940 Act and that the
Trustees may in conjunction with the establishment of any Series of Shares,
establish conditions under which several Series shall have separate voting
rights or no voting rights. There shall be no cumulative Shareholders voting in
the election of Trustees. Until Shares are issued, the Trustees may exercise all
rights of Shareholders and may take any action required by law, the Declaration
or the Bylaws to be taken by Shareholders. The Bylaws may include further
provisions for Shareholders' votes and meetings and related matters.

INCOME DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS--Substantially all of the net
investment income, if any, of each Fund will be paid to shareholders of the
Stock Funds as dividends in March, June, September and December and to
shareholders of the Bond and Money Market Funds at each month end.

In those years in which sales of a Fund's portfolio securities result in net
realized capital gains, the Fund will declare and cause to be paid such gains to
its shareholders in December.


ADDITIONAL GENERAL TAX INFORMATION

   
         Each of the nine Funds of the Trust is treated as a separate entity for
federal income tax purposes and intends to qualify as a "regulated investment
company" under the Internal Revenue Code of 1986, as amended (the "Code"), for
so long as such qualification is in the best interest of that Fund's
shareholders. In order to qualify as a regulated investment company, a Fund
must, among other things: diversify its investments within certain prescribed
limits; derive at least 90% of its gross income from dividends, interest,
payments with respect to securities loans, and gains from the sale or other
disposition of securities or foreign currencies, or other income derived with
respect to its business of investing in such stock, securities, or currencies;
and, in taxable years beginning on or before August 5, 1997, derive less than
30% of its gross income from the sale or other disposition of stock, securities,
options, future contracts or foreign currencies held less than three months. In
addition, to utilize the tax provisions specially applicable to regulated
investment companies, a Fund must distribute to its shareholders at least 90% of
its investment company taxable income for the year. In general, the Fund's
investment company taxable income will be its taxable income subject to certain
adjustments and excluding the excess of any net mid-term or net long-term
capital gain for the taxable year over the net short-term capital loss, if any,
for such year.

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

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

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


                                       31
<PAGE>   77

   
gains will be taxable income to shareholders for federal income tax purposes,
even if paid in additional shares of that Fund and not in cash.

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

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

         Long-term capital gains of individuals are subject to a maximum tax
rate of 20% (10% for individuals in the 15% ordinary income tax bracket).
Mid-term capital gains of individuals are subject to tax at the same rates
applicable to ordinary income; however, the tax rate on mid-term capital gains
of individuals cannot exceed 28%. Capital losses may be used to offset capital
gains. In addition, individuals may deduct up to $3,000 of net capital loss each
year to offset ordinary income. Excess net capital loss may be carried forward
and deducted in future years. The holding period for mid-term capital gains is
more than one year but not more than eighteen months; the holding period for
long-term capital gains is more than eighteen months.

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

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

         Certain corporations are entitled to a 70% dividends received deduction
for distributions from certain domestic corporations. Each Fund will designate
the portion of any distributions which qualify for the 70% dividends received
deduction. The amount so designated may not exceed the amount received by that
Fund for its taxable year that qualifies for the dividends received deduction.
Because all of the Money Market Fund's and each of the Bond Fund's net
investment income is expected to be derived from earned interest and short term
capital gains, it is anticipated that no distributions from such Funds will
qualify for the 70% dividends received deduction.

         Foreign taxes may be imposed on a Fund by foreign countries with
respect to its income from foreign securities. Since less than 50% in value of
any Fund's total assets at the end of its fiscal year are expected to be
invested in stocks or securities of foreign corporations, such Fund will not be
entitled under the Code to pass through to its Shareholders their pro rata share
of the foreign taxes paid by that Fund. These taxes will be taken as a deduction
by the Fund.
    


                                       32
<PAGE>   78

   
         Under Section 1256 of the Code, gain or loss realized by a Fund from
certain financial futures and options transactions will be treated as 60%
long-term capital gain or loss and 40% short-term capital gain or loss. Gain or
loss will arise upon exercise or lapse of such futures and options as well as
from closing transactions. In addition, any such futures and options remaining
unexercised at the end of a Fund's taxable year will be treated as sold for
their then fair market value, resulting in additional gain or loss to such Fund
characterized in the manner described above.

         Offsetting positions held by a Fund involving certain futures contracts
or options transactions may be considered, for tax purposes, to constitute
"straddles." Straddles are defined to include "offsetting positions" in actively
traded personal property. The tax treatment of straddles is governed by Sections
1092 and 1258 of the Code, which, in certain circumstances, overrides or
modifies the provisions of Section 1256. As such, all or a portion of any short
or long-term capital gain from certain straddle and/or conversion transactions
may be recharacterized as ordinary income.

         If a Fund were treated as entering into straddles by reason of its
engaging in futures or options transactions, such straddles would be
characterized as "mixed straddles" if the futures or options comprising a part
of such straddles were governed by Section 1256 of the Code. A Fund may make one
or more elections with respect to mixed straddles. If no election is made, to
the extent the straddle rules apply to positions established by a Fund, losses
realized by such Fund will be deferred to the extent of unrealized gain in any
offsetting positions. Moreover, as a result of the straddle and conversion
transaction rules, short-term capital losses on straddle positions may be
recharacterized as long-term capital losses and long-term capital gains may be
recharacterized as short-term capital gain or ordinary income.

         Investment by a Fund in securities issued at a discount or providing
for deferred interest or for payment of interest in the form of additional
obligations could, under special tax rules, affect the amount, timing and
character of distributions to Shareholders. For example, a Fund could be
required to take into account annually a portion of the discount (or deemed
discount) at which such securities were issued and to distribute such portion in
order to maintain its qualification as a regulated investment company. In that
case, that Fund may have to dispose of securities which it might otherwise have
continued to hold in order to generate cash to satisfy these distribution
requirements.

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

         Information set forth in the prospectuses and this Statement of
Additional Information which relates to Federal taxation is only a summary of
some of the important Federal tax considerations generally affecting purchasers
of shares of the Funds. No attempt has been made to present a detailed
explanation of the Federal income tax treatment of the Funds or their
shareholders and this discussion is not intended as a substitute for careful tax
planning. Accordingly, potential purchasers of shares of a Fund are urged to
consult their tax advisers with specific reference to their own tax situation.
In addition, the tax discussion in the

and regulations which are in effect on the date of the prospectuses and this
Statement of Additional Information; such laws and regulations may be changed by

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



ADDITIONAL TAX INFORMATION WITH RESPECT TO THE TAX-FREE INCOME FUND

         The Tax-Free Income Fund is not intended to constitute a balanced
investment program and is not designed for investors seeking capital
appreciation or maximum tax-exempt income irrespective of fluctuations in
principal. Shares of the Tax-Free Income Fund would not be suitable for
tax-exempt institutions and may not be suitable for retirement plans qualified
under Section 401 of the Code, H.R. 10 plans, and individual retirement
accounts, since such plans and accounts are generally tax-exempt and, therefore,
would not gain any additional benefit from all or a portion of the Tax-Free
Income Fund's dividends being tax-exempt and such dividends would be ultimately
taxable to the beneficiaries when distributed to them. In addition, the Tax-Free
Income Fund may not be an appropriate investment for entities which are
"substantial users," or "related persons" thereof, of facilities financed by
private activity bonds held by the Tax-Free Income Fund.

         The Code permits a regulated investment company which invests in
municipal securities to pay to its shareholders "exempt-interest dividends,"
which are excluded from gross income for federal income tax purposes, if at the
close of each quarter of its taxable year at least 50% of its total assets
consist of municipal securities.

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

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


                                       34
<PAGE>   80

   
continued to purchase or carry shares of the Tax-Free Income Fund if the
Tax-Free Income Fund distributes exempt-interest dividends during the
shareholder's taxable year. Certain federal income tax deductions of property
and casualty insurance companies holding shares of the Tax-Free Income Fund and
receiving exempt-interest dividends may also be adversely affected. In certain
limited instances, the portion of Social Security benefits received by a
shareholder which may be subject to federal income tax may be affected by the
amount of tax-exempt interest income, including exempt-interest dividends
received by shareholders of the Tax-Free Income Fund.

         In the event the Tax-Free Income Fund realizes mid-term or long-term
capital gains, the Tax-Free Income Fund intends to distribute any realized net
mid-term or net long-term capital gains annually. If the Tax-Free Income Fund
distributes such gains, the Tax-Free Income Fund will have no tax liability with
respect to such gains, and the distributions will be taxable to shareholders as
mid-term or long-term capital gains, respectively, regardless of how long the
shareholders have held their shares. Any such distributions will be designated
as a capital gain dividend in a written notice mailed by the Tax-Free Income
Fund to the shareholders not later than sixty days after the close of the
Tax-Free Income Fund's taxable year. It should be noted, however, that long-term
capital gains of individuals are subject to a maximum tax rate of 20% (or 10%
for individuals in the 15% ordinary income tax bracket) and mid-term capital
gains are taxed like ordinary income except that net capital gains of
individuals are subject to a maximum federal income tax rate of 28%. Any net
short-term capital gains are taxed at ordinary income tax rates. If a
shareholder receives a capital gain dividend with respect to any share and then
sells the share before he has held it for more than six months, any loss on the
sale of the share is treated as long-term capital loss to the extent of the
capital gain dividend received.

         Interest earned on certain municipal obligations issued on or after
August 8, 1986, to finance certain private activities will be treated as a tax
preference item in computing the alternative minimum tax. Since the Tax-Free
Income Fund may invest up to 20% of its net assets in municipal securities the
interest on which may be treated as a tax preference item, a portion of the
exempt-interest dividends received by shareholders from the Tax-Free Income Fund
may be treated as tax preference items in computing the alternative minimum tax
to the extent that distributions by the Tax-Free Income Fund are attributable to
such obligations. Also, a portion of all other interest excluded from gross
income for federal income tax purposes earned by a corporation may be subject to
the alternative minimum tax as a result of the inclusion in alternative minimum
taxable income of 75% of the excess of adjusted current earnings and profits
over pre-book alternative minimum taxable income. Adjusted current earnings and
profits would include exempt-interest dividends distributed by the Tax-Free
Income Fund to corporate shareholders. For individuals the alternative minimum
tax rate is 26% on alternative minimum taxable income up to $175,000 and 28% on
the excess of $175,000; for corporations the alternative minimum tax rate is
20%.

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


                                       35
<PAGE>   81

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

         As indicated in the Prospectus, the Tax-Free Income Fund may acquire
rights regarding specified portfolio securities under puts. See "INVESTMENT
OBJECTIVES AND POLICIES -- Additional Information on Portfolio Instruments -
Puts" in this Statement of Additional Information. The policy of the Tax-Free
Income Fund is to limit its acquisition of puts to those under which it will be
treated for federal income tax purposes as the owner of the Exempt Securities
acquired subject to the put and the interest on the Exempt Securities will be
tax-exempt to it. Although the Internal Revenue Service has issued a published
ruling that provides some guidance regarding the tax consequences of the
purchase of puts, there is currently no guidance available from the Internal
Revenue Service that definitively establishes the tax consequences of many of
the types of puts that the Tax-Free Income Fund could acquire under the 1940
Act. Therefore, although the Tax-Free Income Fund will only acquire a put after
concluding that it will have the tax consequences described above, the Internal
Revenue Service could reach a different conclusion.

         Under Section 1256 of the Code, gain or loss realized by the Tax-Free
Income Fund from certain financial futures and options transactions will be
treated as 60% long-term capital gain or loss and 40% short-term capital gain or
loss. Gain or loss will arise upon exercise or lapse of such futures and options
as well as from closing transactions. In addition, any such futures and options
remaining unexercised at the end of the Tax-Free Income Fund's taxable year will
be treated as sold for their then fair market value, resulting in additional
gain or loss to the Tax-Free Income Fund characterized in the manner described
above.

         Offsetting positions held by the Tax-Free Income Fund involving certain
futures contracts or options transactions may be considered, for tax purposes,
to constitute "straddles." Straddles are defined to include "offsetting
positions" in actively traded personal property. The tax treatment of straddles
is governed by Sections 1092 and 1258 of the Code, which, in certain
circumstances, overrides or modifies the provisions of Section 1256. As such,
all or a portion of any short or long-term capital gain from certain straddle
and/or conversion transactions may be recharacterized as ordinary income.

         If the Tax-Free Income Fund were treated as entering into straddles by
reason of its engaging in futures or options transactions, such straddles would
be characterized as "mixed straddles" if the futures or options comprising a
part of such straddles were governed by Section 1256 of the Code. The Tax-Free
Income Fund may make one or more elections with respect to mixed straddles. If
no election is made, to the extent the straddle rules apply to positions
established by the Tax-Free Income Fund, losses realized by the Tax-Free Income
Fund will be deferred to the extent of unrealized gain in any offsetting
positions. Moreover, as a result of the straddle and conversion transaction
rules, short-term capital losses on straddle positions may be recharacterized as
long-term capital losses and long-term capital gains may be recharacterized as
short-term capital gain or ordinary income.
    


                                       36
<PAGE>   82

   
         Investment by the Tax-Free Income Fund in securities issued at a
discount or providing for deferred interest or for payment of interest in the
form of additional obligations could, under special tax rules, affect the
amount, timing and character of distributions to shareholders. For example, the
Tax-Free Income Fund could be required to take into account annually a portion
of the discount (or deemed discount) at which such securities were issued and to
distribute such portion in order to maintain its qualification as a regulated
investment company. In that case, the Tax-Free Income Fund may have to dispose
of securities which it might otherwise have continued to hold in order to
generate cash to satisfy these distribution requirements.

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

SPECIAL MEETING

The Declaration of Trust Indenture provides for a Special Meeting of
Shareholders which may be called by the Trustees or shareholders for the purpose
of taking action on any matter requiring the vote of shareholders as provided
for in the Declaration of Trust.

APPENDIX A

 BOND RATINGS

 STANDARD & POOR'S DEBT RATINGS

         A Standard & Poor's corporate or municipal debt rating is a current
assessment of the creditworthiness of an obligor with respect to a specific
obligation. This assessment may take into consideration obligors such as
guarantors, insurers, or lessees.

         The debt rating is not a recommendation to purchase, sell, or hold a
security, inasmuch as it does not comment as to market price or suitability for
a particular investor. The ratings are based on current information furnished by
the issuer or obtained by Standard & Poor's from other sources it considers
reliable. Standard & Poor's does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information. The
ratings may be changed, suspended, or withdrawn as a result of changes in, or
unavailability of, such information, or for other circumstances.

         The ratings are based, in varying degrees, on the following
considerations:

         1. Likelihood of default - capacity and willingness of the
         obligor as to the timely payment of interest and repayment of
         principal in accordance with the terms of the obligation.

         2. Nature of and provisions of the obligation.

         3. Protection afforded by, and relative position of, the
         obligation in the event of bankruptcy, reorganization, or other
         arrangement under the laws of bankruptcy and other laws affecting
         creditors' rights.

INVESTMENT GRADE

        AAA - Debt rated 'AAA' has the highest rating assigned by Standard &
Poor's. Capacity to pay interest and repay principal is extremely strong.

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

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

        BBB - Debt rated 'BBB' is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher rated categories.

SPECULATIVE GRADE

        Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded as having
predominantly speculative characteristics with respect to capacity to pay
interest and repay principal. 'BB' indicates the least degree of speculation and
'C' the highest. While 



                                       45
<PAGE>   84

such debt will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions.

        BB - Debt rated 'BB' has less near-term vulnerability to default than
other speculative issues. However, it faces major ongoing uncertainties or
exposure to adverse business, financial, or economic conditions which could lead
to inadequate capacity to meet timely interest and principal payments. The 'BB'
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied 'BBB-' rating.

        B - Debt rated 'B' has a greater vulnerability to default but currently
has the capacity to meet interest payments and principal repayments. Adverse
business, financial, or economic conditions will likely impair capacity or
willingness to pay interest and repay principal. The 'B' rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
'BB' or 'BB-' rating.

        CCC - Debt rated 'CCC' has a currently identifiable vulnerability to
default, and is dependent upon favorable business, financial, and economic
conditions to meet timely payment of interest and repayment of principal. In the
event of adverse business, financial, or economic conditions, it is not likely
to have the capacity to pay interest and repay principal. The 'CCC' rating
category is also used for debt subordinated to senior debt that is assigned an
actual or implied 'B' or 'B-' rating.

        CC - Debt rated 'CC' typically is applied to debt subordinated to senior
debt that is assigned an actual or implied 'CCC' rating.

        C - Debt rated 'C' typically is applied to debt subordinated to senior
debt which is assigned an actual or implied 'CCC-' debt rating. The 'C' rating
may be used to cover a situation where a bankruptcy petition has been filed, but
debt service payments are continued.

        CI - The rating 'CI' is reserved for income bonds on which no interest
is being paid.

        D - Debt rated 'D' is in payment default. The 'D' rating category is
used when interest payments or principal payments are not made on the date due
even if the applicable grace period has not expired, unless Standard & Poor's
believes that such payments will be made during such grade period. The 'D'
rating also will be used upon the filing of a bankruptcy petition if debt
service payments are jeopardized.

MOODY'S LONG-TERM DEBT RATINGS

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

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


                                       46
<PAGE>   85

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

        Baa - Bonds which are rated Baa are considered as medium-grade
obligations (i.e., they are neither highly protected nor poorly secured).
Interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

        Ba - Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered well-assured. Often the protection of interest
and principal payments may be very moderate, and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

        B - Bonds which are rated B generally lack characteristics of the
desirable investment. Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small.

        Caa - Bonds which are rated Caa are of poor standing. Such issues may be
in default or there may be present elements of danger with respect to principal
or interest.

        Ca - Bonds which are rated Ca represent obligations which are
speculative in a high degree. Such issues are often in default or have other
marked shortcomings.

        C - Bonds which are rated C are the lowest rated class of bonds, and
issues so rated can be regarded as having extremely poor prospects of ever
attaining any real investment standing.

   
MUNICIPAL BOND

Excerpts from Moody's Investors Service Inc., description of its three highest
bond ratings: Aaa--judged to be the best quality. They carry the smallest degree
of investment risk; Aa--judged to be of high quality by all standards;
A--possess favorable attributes and are considered "upper medium" grade
obligations. Note: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's
believes possess the strongest investment attributes are designated by the
symbol Aa 1, A 1, Ba 1 and B 1.

Excerpts from Standard & Poor's Corporation description of its three highest
bond ratings: AAA--highest grade obligations; AA--also qualify as highgrade
obligations, and, in the majority of instances, differ from AAA issues only in
small degree; A--strong ability to pay interest and repay principle although
more susceptible to change in circumstances.

STATE AND MUNICIPAL NOTES

Excerpts from Moody's Investors Service, Inc., description of state and
municipal note ratings:

MIG-1--Notes bearing this designation are of the best quality, enjoying strong
protection from established cash flows of funds for their servicing from
established and board-based access to the market for refinancing, or both.


                                       47
<PAGE>   86


MIG-2--Notes bearing this designation are of high quality, with margins of
protection ample although not so large as in the preceding group.

MIG-3--Notes bearing this designation are of favorable quality, with all
security elements accounted for but lacking the strength of the preceding grade.
Market access for refinancing, in particular, is likely to be less well
established.
    

  FITCH INVESTORS SERVICE, INC. BOND RATINGS

        Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
represent Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt in a timely manner.

        The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength and credit quality.

        Fitch ratings do not reflect any credit enhancement that may be provided
by insurance policies or financial guaranties unless otherwise indicated.

        Bonds that have the same rating are of similar but not necessarily
identical credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.

        Fitch ratings are not recommendations to buy, sell, or hold any
security. ratings do not comment on the adequacy of market price, the
suitability of any security for a particular investor, or the tax-exempt nature
or taxability of payments made in respect of any security.

        Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such
information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.

AAA      Bonds considered to be investment grade and of the highest credit
         quality. The obligor has an exceptionally strong ability to pay
         interest and repay principal, which is unlikely to be affected by
         reasonably foreseeable events.

AA       Bonds considered to be investment grade and of very high credit
         quality. The obligor's ability to pay interest and repay principal is
         very strong, although not quite as strong as bonds rated 'AAA'. Because
         bonds rated in the 'AAA' and 'AA' categories are not significantly
         vulnerable to foreseeable future developments, short-term debt of the
         issuers is generally rated 'F-1+'.

A        Bonds considered to be investment grade and of high credit quality. The
         obligor's ability to pay interest and repay principal is considered to
         be strong, but may be more vulnerable to adverse changes in economic
         conditions and circumstances than bonds with higher ratings.

BBB      Bonds considered to be investment grade and of satisfactory credit
         quality. The obligor's ability to pay interest and repay principal is
         considered to be adequate. Adverse changes in economic conditions and
         circumstances, however, are 


                                       48
<PAGE>   87

         more likely to have adverse impact on these bonds, and therefore,
         impair timely payment. The likelihood that the ratings of these bonds
         will fall below investment grade is higher than for bonds with higher
         ratings.

        Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
('BB' to 'C') represent Fitch's assessment of the likelihood of timely payment
of principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ('DDD' to 'D') is an
assessment of the ultimate recovery value through reorganization or liquidation.

        The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength.

        Bonds that have the same rating are of similar but not necessarily
identical credit quality since the rating categories cannot fully reflect the
differences in the degrees of credit risk.

BB       Bonds are considered speculative. The obligor's ability to pay interest
         and repay principal may be affected over time by adverse economic
         changes. However, business and financial alternatives can be identified
         which could assist the obligor in satisfying its debt service
         requirements.

B        Bonds are considered highly speculative. While bonds in this class are
         currently meeting debt service requirements, the probability of
         continued timely payment of principal and interest reflects the
         obligor's limited margin of safety and the need for reasonable business
         and economic activity throughout the life of the issue.

CCC      Bonds have certain identifiable characteristics which, if not remedied,
         may lead to default. The ability to meet obligations requires an
         advantageous business and economic environment.

CC       Bonds are minimally protected. Default in payment of interest and/or
         principal seems probable over time.

C        Bonds are in imminent default in payment of interest or principal.

DDD      Bonds are in default on interest and/or principal payments. Such bonds
         are extremely speculative,

DD       and should be valued on the basis of their ultimate recovery value in
         liquidation or reorganization of &D the obligor. `DDD' represents the
         highest potential for recovery of these bonds, and 'D' represents the
         lowest potential for recovery.


DUFF & PHELPS, INC.  LONG-TERM DEBT RATINGS

        These ratings represent a summary opinion of the issuer's long-term
fundamental quality. Rating determination is based on qualitative and
quantitative factors which may vary according to the basic economic and
financial characteristics of each industry and each issuer. Important
considerations are vulnerability to economic cycles as well as risks related to
such factors as competition, government action, 


                                       49
<PAGE>   88

regulation, technological obsolescence, demand shifts, cost structure, and
management depth and expertise. The projected viability of the obligor at the
trough of the cycle is a critical determination.

        Each rating also takes into account the legal form of the security,
(e.g., first mortgage bonds, subordinated debt, preferred stock, etc.). The
extent of rating dispersion among the various classes of securities is
determined by several factors including relative weightings of the different
security classes in the capital structure, the overall credit strength of the
issuer, and the nature of covenant protection. Review of indenture restrictions
is important to the analysis of a company's operating and financial constraints.

        The Credit Rating Committee formally reviews all ratings once per
quarter (more frequently, if necessary). Ratings of 'BBB-' and higher fall
within the definition of investment grade securities, as defined by bank and
insurance supervisory authorities.

RATING
SCALE           DEFINITION
- -----           ----------

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

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

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

BBB+            Below average protection factors but still considered sufficient

SHORT-TERM RATINGS

STANDARD & POOR'S COMMERCIAL PAPER RATINGS

        A Standard & Poor's commercial paper rating is a current assessment of
the likelihood of timely payment of debt considered short-term in the relevant
market.

        Ratings are graded into several categories, ranging from 'A-1' for the
highest quality obligations to 'D' for the lowest. These categories are as
follows:

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

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

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

        B Issues rated 'B' are regarded as having only speculative capacity for
timely payment.

        C This rating is assigned to short-term debt obligations with doubtful
capacity for payment.

        D Debt rated 'D' is in payment default. the 'D' rating category is used
when interest payments or principal payments are not made on the date due, even
if the applicable grace period has not expired, unless Standard & Poor's
believes that such payments will be made during such grade period.

STANDARD & POOR'S NOTE RATINGS

        An S&P note rating reflects the liquidity factors and market-access
risks unique to notes. Notes maturing in three years or less will likely receive
a note rating. Notes maturing beyond three years will most likely receive a
long-term debt rating.

        The following criteria will be used in making the assessment:

        1.     Amortization schedule - the larger the final maturity relative to
               other maturities, the more likely the issue is to be treated as a
               note.

        2.     Source of payment - the more the issue depends on the market for
               its refinancing, the more likely it is to be considered a note.

        Note rating symbols and definitions are as follows:

        SP-1 Strong capacity to pay principal and interest. Issues determined to
possess very strong characteristics are given a plus (+) designation.

        SP-2 Satisfactory capacity to pay principal and interest, with some
vulnerability to adverse financial and economic changes over the term of the
notes.

        SP-3 Speculative capacity to pay principal and interest.

MOODY'S SHORT-TERM RATINGS

        Moody's short-term debt ratings are opinions on the ability of issuers
to repay punctually senior debt obligations. These obligations have an original
maturity not exceeding one year, unless explicitly noted. Moody's employs the
following three designations, all judged to be investment grade, to indicate the
relative repayment capacity of rated issuers:

        Issuers rated Prime-1 (or supporting institutions) have a superior
capacity for repayment of senior short-term debt obligations. Prime-1 repayment
capacity will normally be evidenced by the following characteristics: (I)
leading market positions in well established industries, (II) high rates of
return on funds employed, (III) conservative capitalization structures with
moderate reliance on debt and ample asset protection, (IV) broad margins in
earnings coverage of fixed financial charges and high internal cash generation,
and (V) well established access to a range of financial markets and assured
sources of alternative liquidity.

        Issuers rated Prime-2 (or supporting institutions) have a strong
capacity for repayment of short-term promissory obligations. This will normally
be evidenced by many of the characteristics cited above, but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

        Issuers rated Prime-3 (or supporting institutions) have an acceptable
capacity for repayment of short-term promissory obligations. The effect of
industry characteristics and market composition may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.

        Issuers rated Not Prime do not fall within any of the prime rating
categories.

MOODY'S NOTE RATINGS

         MIG 1/VMIG 1 This designation denotes best quality. There is present
strong protection by established cash flows, superior liquidity support or
demonstrated broad based access to the market for refinancing.

         MIG 2/VMIG 2 This designation denotes high quality. Margins of
protection are ample although not so large as in the preceding group.

         MIG 3/VMIG 3 This designation denotes favorable quality. All security
elements are accounted for but there is lacking the undeniable strength of the
preceding grades. Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.

         MIG 4/VMIG 4 This designation denotes adequate quality. Protection
commonly regarded as required of an investment security is present and although
not distinctly or predominantly speculative, there is specific risk.

         SG This designation denotes speculative quality. Debt instruments in
this category lack margins of protection.

FITCH'S SHORT-TERM RATINGS

        Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of generally up to three years, including
commercial paper, certificates of deposit, medium-term notes, and municipal and
investment notes.

        The short-term rating places greater emphasis than a long-term rating on
the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.

                     F-1+ Exceptionally strong credit quality. Issues assigned
               this rating are regarded as having the strongest degree of
               assurance for timely payment.

                     F-1 Very strong credit quality. Issues assigned this rating
               reflect an assurance of timely payment only slightly less in
               degree than issues rated 'f-1+'.

                     F-2 Good credit quality. Issues assigned this rating have a
               satisfactory degree of assurance for timely payment but the
               margin of safety is not as great as for issues assigned 'F-1+'
               and 'F-1' ratings.

                     F-3 Fair credit quality. Issues assigned this rating have
               characteristics suggesting that the degree of assurance for
               timely payment is adequate, however, near-term adverse changes
               could cause these securities to be rated below investment grade.

                     F-S Weak credit quality. Issues assigned this rating have
               characteristics suggesting a minimal degree of assurance for
               timely payment and are vulnerable to near-term adverse changes in
               financial and economic conditions.

                     D Default. Issues assigned this rating are in actual or
               imminent payment default.


                     LOC The symbol LOC indicates that the rating is based on a
               letter of credit issued by a commercial bank.


DUFF & PHELPS SHORT-TERM DEBT RATINGS

        Duff & Phelps' short-term ratings are consistent with the rating
criteria utilized by money market participants. The ratings apply to all
obligations with maturities under one year, including commercial paper, the
uninsured portion of certificates of deposit, unsecured bank loans, master
notes, bankers acceptances, irrevocable letters of credit, and current
maturities of long-term debt.
Asset-backed commercial paper is also rated according to this scale.

        Emphasis is placed on liquidity which is defined as not only cash from
operations, but also access to alternative sources of funds including trade
credit, bank lines, and the capital markets. An important consideration is the
level of an obligor's reliance on short-term funds on an ongoing basis.

RATING SCALE   DEFINITION
- ------------   ----------

               HIGH GRADE
               ----------

        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 short-term 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.

                   GOOD GRADE
                   ----------

        D-2        Good certainty of timely payment. Liquidity factors and
               company fundamentals are sound. Although ongoing funding needs
               may enlarge total financing requirements, access to capital
               markets is good. Risk factors are small.

                   SATISFACTORY GRADE
                   ------------------

        D-3        Satisfactory liquidity and other protection factors qualify
               issue as to investment grade. Risk factors are larger and subject
               to more variation. Nevertheless, timely payment is expected.

                   NON-INVESTMENT GRADE
                   --------------------

        D-4        Speculative investment characteristics. Liquidity is not
               sufficient to insure against disruption in debt service.
               Operating factors and market access may be subject to a high
               degree of variation.

                   DEFAULT
                   -------

        D-5        Issuer failed to meet scheduled principal and/or interest
               payments.


THOMSON'S SHORT-TERM RATINGS

        The Thomson Short-Term Ratings apply, unless otherwise noted, to
specific debt instruments of the rated entities with a maturity of one year or
less. Thomson short-term ratings are intended to assess the likelihood of an
untimely or incomplete payments of principal or interest.

        TBW-1 the highest category, indicates a very high likelihood that
principal and interest will be paid on a timely basis.

        TBW-2 the second highest category, while the degree of safety regarding
timely repayment of principal and interest is strong, the relative degree of
safety is not as high as for issues rated "TBW-1".
 
        TBW-3 the lowest investment-grade category; indicates that while the
obligation is more susceptible to adverse developments (both internal and
external) than those with higher ratings, the capacity to service principal and
interest in a timely fashion is considered adequate.


                                       54
<PAGE>   93

        TBW-4 the lowest rating category; this rating is regarded as
non-investment grade and therefore speculative.

IBCA SHORT-TERM RATINGS

        IBCA short-term ratings assess the borrowing characteristics of banks
and corporations, and the capacity for timely repayment of debt obligations. The
short-term ratings relate to debt which has a maturity of less than one year.

        IBCA issues ratings and reports on the largest U.S. and international
bank holding companies, as well as major investment banks. IBCA's short-term
rating system utilizes a dual system--Individual Ratings and Legal Ratings. The
Individual Rating addresses 1) the current strength of consolidated banking
companies and their principal bank subsidiaries. A consolidated bank holding
company/bank with an "A" rating has a strong balance sheet, and a favorable
credit profile without significant problems. A "B" rating indicates sound credit
profile without significant problems. Performance is generally in line with or
better than that of its peers. The legal rating addresses the question of
whether an institution would receive support if it ran into difficulties. Issues
rated "A-1" are obligations supported by a very strong capacity for timely
repayment. Issues rated "A-2" have a very strong capacity for timely repayment
although such capacity may be susceptible to adverse changes in business,
economic or financial conditions.

                A1+  Obligations supported by the highest capacity for timely
                     repayment and possess a particularly strong credit feature.

                A1   Obligations supported by the highest capacity for timely
                     repayment.

                A2   Obligations supported by a good capacity for timely
                     repayment.

                A3   Obligations supported by a satisfactory capacity for timely
                     repayment.

                B    Obligations for which there is an uncertainty as to the
                     capacity to ensure timely repayment.

                C    Obligations for which there is a high risk of default or
                     which are currently in default.

                D    Obligations which are currently in default.

BOND RATINGS

Bonds rated AA or AAA by D&P are deemed to be high quality. Protection factors
are strong. Risk is modest but may vary slightly from time to time because of
economic conditions.

Bonds rated AA or AAA by Fitch are considered to be investment grade and of very
high credit quality. The obligor's ability to pay interest and repay principal
is very strong.

Moody's three highest bond ratings are: Aaa - judged to be the best quality -
carry the smallest degree of investment risk; Aa - judged to be high quality by
all standards; A possess favorable attributes and are considered "upper medium"
grade obligations.

S&P's three highest bond ratings are: AAA - highest grade obligations - possess
the ultimate degree of protection and indicates an extremely strong capacity to
pay 


                                       55
<PAGE>   94

principal and interest; AA - also qualify as high grade obligations, and in
the majority of instances differ only in small degrees from issues rated AAA; A
- - strong ability to pay interest and repay principal although more susceptible
to change in circumstances.

Bonds rated AA or AAA by IBCA indicates a very strong capacity for timely
repayment of debt. Margins of protection may not be as large as for AAA issues.

Bonds rated AA or AAA by Thomson indicates ability to repay principal and
interest on a timely basis. Bonds rated AA may have limited incremental risk
versus AAA issues.

Bonds BBB are regarded as having an adequate capacity to pay interest and repay
principal. Whereas it normally exhibits adequate protection parameters, adverse
economic conditions or changing circumstances are more likely to lead to a
weakened capacity to repay principal for debt in this category than in higher
rated categories.

      in accordance with the provisions hereof, and reference herein to a
      Trustee or the Trustees shall refer to such person or persons in their
      capacity as trustee or trustees hereunder.

      Section 1.3. Purposes of Trust. The purposes of the Trust are to operate
as an investment company as defined in the 1940 Act and to engage in any lawful
activity for which business trusts may be formed under Chapter 1746, Ohio
Revised Code.

                                   ARTICLE II

                                    TRUSTEES

      Section 2.1. Initial Trustees. Upon the execution of this Declaration of
Trust or a counterpart hereof or some other writing in which each of the
Trustees accepts such trusteeship and agrees to the provisions hereof, each of
the Trustees listed at the end of this Declaration of Trust shall become the
initial Trustees of the Trust.

      Section 2.2. Number of Trustees. The number of Trustees shall be such
number as shall be fixed from time to time by a written instrument signed by a
majority of the Trustees. The Trustees serving as such, whether described in
Section 2.1 above or hereafter becoming a Trustee, may increase or decrease the
number of Trustees to a number other than the number theretofore determined. A
Trustee shall qualify by accepting in writing his election or appointment and
agreeing to be bound by the Declaration of Trust. No decrease in the number of
Trustees shall have the effect of removing any Trustee from office prior to the
expiration of his or her term, but the number of Trustees may be decreased in
conjunction with the removal of a Trustee pursuant to Section 2.4.

      Section 2.3. Election and Term. Except for the Trustees named herein or
appointed to fill vacancies pursuant to Section 2.5 hereof, the Trustees shall
be elected by the Shareholders, who shall vote as a single class and not by
Series and shall vote at such times as the Trustees shall determine that such
election is required by the 1940 Act or is otherwise advisable. There is no
requirement that the Trustees have an annual meeting of the Shareholders. In the
event the Trustees determine to have an annual or special meeting of the
Shareholders at which Trustees will be elected, it shall be held at such time
and place and in such manner as the Bylaws shall provide notwithstanding
anything in this section to the contrary. Except in the event of death,
resignation or removal, each of the Trustees shall hold office until the next
meeting of Shareholders called for the purpose of electing Trustees and until
his successor is elected and qualified to serve as Trustee.

      Section 2.4. Resignation and Removal. Any Trustee may resign his trust
(without need for prior or subsequent accounting except to the extent required
by the 1940 Act or under circumstances that would justify the Trustee's removal
for cause and then only if required by the remaining Trustees) by an instrument
in writing signed by him and delivered to the other Trustees or to any officer
of the Trust or at a meeting of the Trustees, and such resignation shall be
effective upon


                                        3
<PAGE>   7

such delivery, or at a later date according to the terms of the instrument. Any
of the Trustees may be removed with or without cause, by the written action of
two-thirds of the number of Trustees prior to such removal or by Shareholders at
any meeting called for that purpose. No Trustee shall be entitled to any damages
on account of such removal. Upon the resignation or removal of a Trustee, or his
otherwise ceasing to be a Trustee, he shall execute and deliver such documents
as the remaining Trustees shall require for the purpose of conveying to the
Trust or the remaining Trustees any Trust Property held in the name of the
resigning or removed Trustee. Upon the incapacity or death of any Trustee, his
legal representative shall execute and deliver on his behalf such documents as
the remaining Trustees shall require as provided in the preceding sentence.

      Section 2.5. Vacancies. The term of office of a Trustee shall terminate
and a vacancy shall occur in the event of the death, resignation, removal,
bankruptcy, adjudicated incompetence or other incapacity to perform the duties
of the office of a Trustee. No such vacancy shall operate to annul this
Declaration or to revoke any existing agency or contract created or entered into
pursuant to the terms of the Declaration. In the case of an existing vacancy,
including a vacancy existing by reason of an increase in the number of Trustees
as set forth in Section 2.2. hereof, subject to the provisions of Section 16(a)
of the 1940 Act, the remaining Trustees may fill such vacancy by the appointment
of such other person or persons as they in their discretion shall see fit, made
by a written instrument signed by a majority of the remaining Trustees. Any such
appointment shall not become effective, however, until the person named in the
written instrument of appointment shall have accepted in writing such
appointment and agreed in writing to be bound by the terms of the Declaration.
An appointment of a Trustee may be made in anticipation of a vacancy to occur at
a later date by reason of retirement, resignation or increase in the number of
Trustees, provided that such appointment shall not become effective prior to
such retirement, resignation or increase in the number of Trustees. Whenever a
vacancy in the number of Trustees shall occur, until such vacancy is filled as
provided in this Section 2.5., the Trustees in office, regardless of their
number, shall have all the powers granted to the Trustees and shall discharge
all the duties imposed upon the Trustees by the Declaration. A written
instrument certifying the existence of such vacancy signed by a majority of the
Trustees shall be conclusive evidence of the existence of such vacancy.

      Notwithstanding the foregoing, to the extent the Trust adopts and
implements a written plan pursuant to Rule 12b-1 under the 1940 Act, and so long
as required by the 1940 Act, the selection and nomination of Trustees who are
"interested persons" of the Trust as defined in the 1940 Act, shall be committed
to the discretion of the Trustees who are not "interested persons," as so
defined.

      Section 2.6. Delegation of Power to Other Trustees. Any Trustee may, by
power of attorney, delegate his power for a period not exceeding six (6) months
at any one time to any other Trustee or Trustees; provided that in no case shall
less than two (2) Trustees personally exercise the powers granted to the
Trustees under the Declaration except as herein otherwise expressly provided and
except to the extent that the exercise of such power would be prohibited by the
1940 Act.

                                   ARTICLE III

                               POWERS OF TRUSTEES

      Section 3.1. General. The Trustees shall have exclusive and absolute
control over the Trust Property and over the business of the Trust to the same
extent as if the Trustees were the sole owners of the Trust Property and
business in their own right, but with such powers of delegation as may be
permitted by the Declaration. The Trustees shall have power to conduct the
business of the Trust and carry on its operations and maintain offices both
within and without the State of Ohio, in any and all states of the United States
of America, in the District of Columbia, and in any and all commonwealths,
territories, dependencies, colonies, possessions, agencies or instrumentalities
of the United States of America and of foreign governments, and to do all such
other things and execute all such instruments as they deem necessary, proper or
desirable in order to promote the interests of the Trust although such things
are not herein specifically mentioned. Any determination as to what is in the
interest of the Trust made by the Trustees in good faith shall be conclusive. In
construing the provisions of the Declaration, the presumption shall be in favor
of a grant of power to the Trustees.

      The enumeration of any specific power herein shall not be construed as
limiting the aforesaid power. Such powers of the Trustees may be exercised
without order of or resort to any court.

Section 3.2. Investments. The Trustees shall have the power to:

      (a) Conduct, operate and carry on the business of an investment company

      common and preferred stocks; shares of other investment companies;

      securities, including securities of any state, municipality or other
      political subdivision, or any governmental or quasi-governmental agency or
      instrumentality; and money market instruments including bank certificates
      of deposit, finance paper, commercial paper, bankers' acceptances and all
      kinds of repurchase agreements, of any corporation, company, trust,

      of any country, state, municipality or other political subdivisions, or
      any governmental or quasi-governmental agency or instrumentality;

      (c) Acquire (by purchase, subscription or otherwise), to hold, to trade in
      and deal in, to acquire or write any rights or options to purchase or

      contracts, to purchase and sell futures contracts on securities,
      securities indices and foreign currencies, to purchase or sell options on
      such contracts, foreign currency contracts and foreign currencies and to
      engage in all types of hedging and risk management transactions;


                                        5
<PAGE>   9

      (d) Exercise all rights, powers and privileges of ownership or interest in
      all securities included in the Trust Property, including the right to vote
      thereon and otherwise act with respect thereto, to exercise the powers and
      rights of subscription, and to do all acts for the preservation,
      protection, improvements and enhancement in value of all such securities;

      (e) Join with other holders of any securities or debt instruments in
      acting through a committee, depository, voting trustee or otherwise, and
      in that connection to deposit any security or debt instrument with, or
      transfer any security or debt instrument to, any such committee,
      depository or trustee, and to delegate to them such power and authority
      with relation to any security or debt instrument (whether or not so
      deposited or transferred) as the Trustees shall deem proper, and to agree
      to pay, and to pay, such committee, depository or trustee as the Trustees
      shall deem proper;

      (f) Acquire (by purchase, lease or otherwise) and to hold, use, maintain,
      develop and dispose of (by sale or otherwise) any property, real or
      personal, including cash, and any interest therein;

      (g) Act as a distributor of shares and as underwriter of, or broker or

      (h) Allocate assets, liabilities and expenses of the Trust to a particular
      Series or Class of Shares or to apportion the same among two or more

      assets of that Series;

      (i) Consent to or participate in any plan for the reorganization,
      consolidation or merger of any corporation or issuer the security or debt
      instrument of which is or was held in the Trust; to consent to any

quorum being present), including any meeting held by means of a conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, or by written consents of a
majority of the Trustees (unless a higher proportion is required by the 1940 Act
or other applicable law). The Trustees may adopt Bylaws not inconsistent with
this Declaration to provide for the conduct of the business of the Trust and may
amend or repeal such Bylaws to the extent such power is not reserved to the
Shareholders.

      Notwithstanding the foregoing provisions of this Section 3.9 and in
addition to such provisions or any other provision of this Declaration or of the
Bylaws, the Trustees may by resolution appoint a committee consisting of less
than the whole number of Trustees then in office, which committee may be

guarantee indebtedness or contractual obligations of others; (h) determine and
change the fiscal year of the Trust and the method by which its accounts shall

good faith business judgment, to dismiss any action, suit, proceeding, dispute,
claim, or demand, derivative or otherwise, brought by any person, including a
Shareholder in its own name or the name of the Trust, whether or not the Trust
or any of the Trustees may be named individually therein or the subject matter

to time enter into a contract, providing for the sale of Shares to the Trust at
not less than the net asset value per Share (as described in Article VIII

provisions of the 1940 Act, but not withstanding any limitations of present and
future law or custom in regard to delegation of powers by trustees generally,

exclusive or non-exclusive contracts with any one or more corporations, trusts,
associations, partnerships, limited partnerships, other types of organizations

assumption of the services, duties and responsibilities to, for or of the Trust
and /or the Trustees as described in Sections 4.1, 4.2, 4.3, and 4.4 above and
to provide for the performance and assumption of such other services, duties and
responsibilities in addition to those set forth above as the Trustees may
determine appropriate (collectively, such services, duties and responsibilities
are referred to as "Services").

      The same person may be the Contracting Party for some or all of the

interpretive of or in addition to the delineation of the Services for, including
provisions (to the extent consistent with the 1940 Act) relating to the standard
of duty of and the rights to indemnification of the Contacting Party and others,

<PAGE>   14

      Contracting Party or any parent or affiliate thereof is a Shareholder or

      (b) any Contracting Party may have a contract providing for the rendering
      of any similar Services to one or more other corporations, trusts,
      associations, partnerships, limited partnerships or other organizations,
      or has other business or interests

shall not affect the validity of any contract for the performance and assumption
of Services or disqualify any Shareholder, Trustee or officer of the Trust from
voting upon or executing the same or create any liability or accountability to
the Trust or its Shareholders, provided in the case of any relationship or
interest referred to in the preceding clause (a) on the part of on the part of

interest (even though such unrelated or disinterested Trustees are less than a
quorum of all of the Trustees); or (ii) the material facts as to such
relationship or interest and as to the contract have been disclosed to or are
known by the Shareholders entitled to vote thereon and the contract involved is
specifically approved in good faith by vote of the Shareholders; or (iii) the

                                    ARTICLE V

                    LIMITATIONS OF LIABILITY OF SHAREHOLDERS
                               TRUSTEES AND OTHERS

      Section 5.1. No Personal Liability of Shareholders, Trustees, etc. No
Trustee, officer, employee or agent of the Trust shall be subject to any
personal liability whatsoever to any Person, other than the Trust or its
Shareholders, in connection with Trust Property or the affairs of the Trust,
except that arising from bad faith, willful misfeasance, gross negligence or
reckless disregard for his duty to such Person; and all such Persons shall look
solely to the Trust Property for satisfaction of claims of any nature arising in
connection with the affairs of the Trust.

      No Shareholder as such shall be subject to any personal liability
whatsoever to any Person in connection with Trust Property or the acts,
obligations or affairs of the Trust. If any Shareholder or former Shareholder
shall be charged or held personally liable for any obligation or liability of
the Trust solely by reason of being or having been a Shareholder and not because
of such Shareholder's acts or omissions or for some other reason, the Trust
(upon proper and timely request by the Shareholder) shall assume the defense
against such charge and satisfy any judgment or settlement thereon, and the


                                       11
<PAGE>   15

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 assets of the
Trust Property to be held harmless from and indemnified against all loss and
expense arising from such liability.

      The exercise by the Trustees of their powers and discretion hereunder
shall be binding upon everyone interested. A Trustee shall be liable for his own
willful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of the office of Trustee, and for nothing else,
and shall not be liable for errors of judgment or mistakes of fact or law.
Subject to the foregoing, (a) the Trustees shall not be responsible or liable in
any event for any neglect or wrongdoing of any officer, agent, employee,
consultant, Investment Adviser, Distributor, Administrator, or Transfer Agent of
the Trust, nor shall any Trustee be responsible for the act or omission of any
other Trustee; and (b) the Trustees may rely on the advice of counsel or experts
as described in Section 5.6 below.

      Section 5.2. Mandatory Indemnification.

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

            (i) Every person who is, or has been a Trustee or officer of the
            Trust shall be indemnified by the Trust against all liability and
            against all expenses reasonably incurred or paid by him in
            connection with any claim, action, suit or proceeding in which he
            becomes involved as a party or otherwise by virtue of his being or
            having been a Trustee or officer and against amounts paid or
            incurred by him in the settlement thereof.

            (ii) The words "claim", "action", "suit" or "proceeding" shall apply
            to all claims, actions, suits or proceedings (civil, criminal or
            other, including appeals), actual or threatened; and the words
            "liability" and "expenses" shall include, without limitation,
            attorneys' fees, costs, judgments, amounts paid in settlement,
            fines, penalties and other liabilities.

      (b)   No indemnification shall be provided hereunder to a Trustee or
            officer:

            (i) against any liability to the Trust or the Shareholders by reason
            of a final adjudication by the court or other body before which the
            proceeding was brought that he engaged in willful misfeasance, bad
            faith, gross negligence or reckless disregard of the duties involved
            in the conduct of his office;

            (ii) with respect to any matter as to which he shall have been
            finally adjudicated not to have acted in good faith or in the
            reasonable belief that his action was in or not opposed to the best
            interest of the Trust; or

            (iii) in the event of a settlement or other disposition not
            involving a final adjudication as provided in paragraphs (b)(i) or
            (b)(ii) resulting in a payment by a


                                       12
<PAGE>   16

            Trustee or officer, unless there has been either a determination
            that such Trustee or officer did not engage in willful misfeasance,
            bad faith, gross negligence or reckless disregard of the duties
            involved in the conduct of his office by the court or other body
            approving the settlement or other disposition or by a reasonable
            determination, based upon a review of readily available facts (as
            opposed to a full trial-type inquiry) that he did not engage in such
            conduct:

                  (A) by vote of a majority of the Disinterested Trustees acting
                  on the matter (provided that a majority of the Disinterested
                  Trustees then in office act on the matter); or

                  (B) by written opinion of independent legal counsel.

      (c) The rights of indemnification herein provided may be insured against
      by policies maintained by the Trust, shall be severable, shall not affect
      any other rights to which any Trustee or officer may now or hereafter be
      entitled, shall continue as to a Person who has ceased to be such Trustee
      or officer and shall inure to the benefit of the heirs, executors and
      administrators of such Person. Nothing contained herein shall affect any
      rights to indemnification to which personnel other than Trustees and
      officers may be entitled by contract or otherwise under law.

      (d) Expenses of preparation and presentation of a defense to any claim,
      action, suit or proceeding of the character described in paragraph (a) of
      this Section 5.2 shall be advanced by the Trust prior to final disposition
      thereof upon receipt of an undertaking by or on behalf of the recipient to
      repay such amount if it is ultimately determined that he is not entitled
      to indemnification under this Section 5.2, provided that either:

            (i) such undertaking is secured by a surety bond or some other
            appropriate security or the Trust shall be insured against losses
            arising out of any such advances; or

            (ii) a majority of the Disinterested Trustees acting on the matter
            (provided that a majority of the Disinterested Trustees then in
            office act on the matter) or an independent legal counsel in a
            written opinion, shall determine, based upon a review of readily
            available facts (as opposed to a full trial-type inquiry), that
            there is reason to believe that the recipient ultimately will be
            found entitled to indemnification.

      As used in this Section 5.2, a "Disinterested Trustee" is one (i) who is
not an "Interested Person" of the Trust (including anyone who has been exempted
from being an "Interested Person" by any rule, regulation or order of the
Commission), and (ii) against whom none of such actions, suits or other
proceedings or another action, suit or other proceeding on the same similar
grounds is then or had been pending.

<PAGE>   17

      Agents and employees of the Trust who are not Trustees or officers of the
Trust may be indemnified under the same standards and procedures set forth in
this Section 5.2., in the discretion of the Board.

      Section 5.4. No Bond Required of Trustees. No Trustee shall be obligated
to give any bond or other security for the performance of any of his duties
hereunder.

      Section 5.5. No Duty of Investigation; Notice in Trust Instruments, etc.
All Persons extending credit to, contracting with or having any claim against
the Trust shall look only to the assets of the Trust for payment under such
credit, contract or claim; and neither the Shareholders nor the Trustees, nor
any of the Trust's officers, employees or agents, whether past, present or
future, shall be personally liable therefor. Every obligation, contract,
instrument, certificate, Share, other security of the Trust or undertaking, and
every other act or thing whatsoever executed in connection with the Trust shall
be conclusively presumed to have been executed or done by the executors thereof
only in their capacity as Trustees under the Declaration or in their capacity as
officers, employees or agents of the Trust and not personally. Every written
obligation, contract, instrument, certificate, Share, other security of the
Trust or undertaking made or issued by the Trustees or by any officer, employee
or agent may give notice that this Declaration of Trust is on file with the
Secretary of State of Ohio and recite that the same is executed or made by them
not individually, but as Trustee, officer, employee or agent, and that the
obligations of any such instrument are not binding upon any of the them or
Shareholders, individually, but bind only the estate of the applicable Trust,
Series or Class, as set forth in Section 1746.13(A), Ohio Revised Code, and may
contain any further recital which they or he may deem appropriate, but the
omission of such recital shall not operate to bind the Trustees individually.
The Trustees may at all times maintain insurance for the protection of the Trust
Property, its Shareholders, Trustees, officers, employees and agents in such
amount as the Trustees shall deem adequate to cover possible tort liability, and
such other insurance as the Trustees in their sole judgment shall deem
advisable.

      Section 5.6. Reliance on Experts, etc. Each Trustee and officer or
employee of the Trust shall, in the performance of his duties, be fully and
completely justified and protected with regard to any act or any failure to act
resulting from reliance in good faith upon the books of account or other records
of the Trust, upon an opinion of counsel, or upon reports made to the Trust by
any of its officers or employees or by the Investment Adviser, the Distributor,
the Administrator, Transfer Agent, selected dealers, accountants, appraisers or
other experts or consultants selected with reasonable care by the Trustees,
officers or employees of the Trust, regardless of whether such counsel or expert
may also be a Trustee.

      Section 5.7. Indemnification not Exclusive, etc. The right of
indemnification provided by this Article V shall not be exclusive of or affect
any other rights to which any Trustee or officer may be entitled. As used in
this Article V, Trustee or officer shall include such person's heirs, executors
and administrators. Nothing contained in this Article V shall affect any rights
to indemnification to which personnel of the Trust, other than any Trustee or
officer, may be entitled, by contract or otherwise under law, nor the power of
the Trust to purchase and maintain liability insurance on behalf of any such
person.

      Section 5.8. Liability of Series. 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 the management
thereof, shall be paid only from the assets belonging to that Series or Class.

                          SHARES OF BENEFICIAL INTEREST

      Section 6.1. Beneficial Interest. The interest of the Shareholders
hereunder shall be divided into transferable shares of beneficial interest,
without par value. The number of shares of beneficial interest authorized
hereunder, and the number of Shares of each Series or Class thereof that may be
issued hereunder is unlimited. The Trustees shall have the exclusive authority
without the requirement of Shareholder authorization or approval to establish
and designate one or more Series of Shares and one or more Classes thereof as
the Trustees deem necessary, appropriate or desirable. Each Share of any Series
shall represent a beneficial interest only in the assets of that Series. Subject
to the provisions of Section 6.12 hereof, the Trustees may also authorize the
creation of additional Series of Shares (the proceeds of which may be invested
in separate and independent investment portfolios) and additional Classes of
Shares within any Series. All Shares issued hereunder including, without
limitation, Shares issued in connection with a dividend in Shares or a split of
Shares, shall be fully paid and non-assessable.

      Section 6.2. Establishment and Designation of Series. Without limiting the
authority of the Trustees set forth above to establish and designate any further
Series or Class or to classify all or any part of the issued Shares of any
Series to make them part of an existing or newly created Class or to amend
rights and preferences of new or existing Series or Class, including the
following Series, all without Shareholder approval, there are hereby established
and designated (i) initial Series of Shares designated Series A, which shall
represent interests in the Nationwide Mid Cap Growth Fund, Series B, which shall
represent interests in the Nationwide Growth Fund, Series C, which shall
represent interests in the Nationwide Fund, Series D, which shall represent
interests in the Nationwide Bond Fund, Series E, which shall represent interests
in the Nationwide Tax-Free Income Fund, Series F, which shall represent
interests in the Nationwide Long-Term U.S. Government Bond Fund, Series G, which
shall represent interests in the Nationwide Intermediate U.S. Government Bond
Fund, Series H, which shall represent interests in the Nationwide Money Market
Fund and Series I, which shall represent interests in the Nationwide S&P 500
Index Fund, (ii) one Class of Shares for each current Series of the Trust, other
than Series H and I, which Class shall be known as Class D Shares. Series I will
be issued without any class designation.

      Section 6.3. Rights of Shareholders. The ownership of the Trust Property
and the property of each Series of the Trust of every description and the right
to conduct any business hereinbefore described are vested exclusively in the
Trustees, and the Shareholders shall have no interest therein other than the
beneficial interest conferred by their Shares, and they shall have no right to
call for any partition or division of any property, profits, rights or interests
of the Trust nor can they be called upon to assume any losses of the Trust or
suffer an assessment of any kind by virtue of their ownership of Shares. Every
Shareholder by virtue of having become a Shareholder shall be held to


                                       15
<PAGE>   19

have expressly assented and agreed to the terms hereof and to have become a
party hereto. The Shares shall be personal property giving only the rights in
the Declaration specifically set forth. The Shares shall not entitle the holder
to preference, preemptive, appraisal, conversion or exchange rights, except as
the Trustees may determine with respect to any Series or Class of Shares. The
death of a Shareholder during the continuance of the Trust shall not operate to
terminate the Trust nor entitle the representative of any deceased Shareholder
to an accounting or to take any action in court or elsewhere against the Trust
or the Trustees, but only to the rights of said decedent under this Declaration
of Trust.

      Section 6.4. Trust Only. It is the intention of the Trustees to create
only the relationship of Trustee and beneficiary between the Trustees and each
Shareholder from time to time. It is not the intention of the Trustees to create
a general partnership, limited partnership, joint stock association,
corporation, bailment or any form of legal relationship other than an Ohio
business trust. Nothing in the Declaration shall be construed to make the
Shareholders, either by themselves or with the Trustees, partners or members of
a joint stock association.

      Section 6.5. Issuance of Shares . The Trustees, in their discretion, may,
from time to time without vote of the Shareholders, issue Shares, in addition to
the then issued and outstanding Shares and Shares held in the treasury, to such
party or parties and for such amount and type of consideration, including cash
or property, at such time or times (including, without limitation, each business
day in accordance with the determination of net asset value per Share as set
forth in Section 8.1 hereof), and on such terms as the Trustees may deem best,
except that only Shares previously contracted to be sold may be issued during
any period when the right of redemption is suspended, and may in such manner
acquire other assets (including the acquisition of assets subject to, and in
connection with the assumption of liabilities) and businesses. In connection
with any issuance of Shares, the Trustees may issue fractional Shares and
reissue and resell full and fractional Shares held in the treasury. Any
outstanding fractional Share of any Series shall carry proportionately all the
rights and obligations of a whole Share of that Series, including with respect
to voting, receipt of dividends and distributions, redemption of Shares, and
liquidation of the Trust. Shares may also be issued in separate Series or
Classes as provided in Section 6.12 hereof. The Trustees may from time to time
divide or combine the Shares into a greater or lesser number without thereby
changing the proportionate beneficial interests in the Trust. Contributions to
the Trust may be accepted for, and Shares shall be redeemed as, whole Shares
and/or 1/1,000ths of a Share or integral multiples thereof.

      Section 6.6. Register of Shares; Share Certificates. A register will be
kept at the principal office of the Trust or at an office of the Transfer Agent
which shall contain the names and addresses of the Shareholders and the number
of Shares held by them respectively and a record of all transfers thereof. Such
register shall be conclusive as to who are the holders of the Shares and who
shall be entitled to receive dividends or distributions or otherwise to exercise
or enjoy the rights of Shareholders. No Shareholder shall be entitled to receive
payment of any dividend or distribution, nor to have notice given to him as
herein or in the Bylaws provided, until he has given his address to the Transfer
Agent or such other officer or agent of the Trustees as shall keep the said
register for entry thereon. It is not contemplated that certificates will be
issued for the Shares; however, the Trustees, in their discretion, may authorize
the issuance of Share certificates and promulgate appropriate rules and
regulations as to their use.


                                       16
<PAGE>   20

      Section 6.7. Transfer of Shares. Shares shall be transferable on the
records of the Trust only by the record holder thereof or by his agent thereunto
duly authorized in writing, upon delivery to the Trustees or the Transfer Agent
of a duly executed instrument of transfer, together with such evidence of the
genuineness of each such execution and authorization and of other matters as may
reasonably be required. Upon such delivery, the transfer shall be recorded on
the register of the Trust. Until such record is made, the Shareholder of record
shall be deemed to be the holder of such Shares for all purposes hereunder and
neither the Trustees nor any Transfer Agent or registrar nor any officer,
employee or agent of the Trust shall be affected by any notice of the proposed
transfer.

      Any person becoming entitled to any Shares in consequence of the death,
bankruptcy, or incompetence of any Shareholder, or otherwise by operation of
law, shall be recorded on the register of Shares as the holder of such Shares
upon production of the proper evidence thereof to the Trustees or the Transfer
Agent, but until such record is made, the Shareholder of record shall be deemed
to be the holder of such Shares for all purposes hereunder and neither the
Trustees nor any Transfer Agent or registrar nor any officer or agent of the
Trust shall be affected by any notice of such death, bankruptcy or incompetence,
or other operation of law.

      Section 6.8. Notices. Any and all notices to which any Shareholder may be
entitled and any and all communications shall be deemed duly served or given if
mailed, postage prepaid, addressed to any Shareholder of record at his last
known address as recorded on the register of the Trust.

      Section 6.9. Treasury Shares. Shares held in the treasury shall, until
reissued pursuant to Section 6.5, not confer any voting rights on the Trustees,
nor shall such Shares be entitled to any dividends or other distributions
declared with respect to the Shares.

      Section 6.10. Voting Powers. The Shareholders shall have power to vote
only (i) for the election of Trustees as provided in Section 2.3 hereof or as
required by Section 16 (a) of the 1940 Act; (ii) with respect to any investment
advisory or management contract as provided in Section 4.1; (iii) with respect
to termination or reorganization of the Trust or any Series or Class as provided
in Section 9.2.; (iv) with respect to any amendment of the Declaration to the
extent and as provided in Section 9.3; (v) with respect to any merger,
consolidation or sale or disposition of assets as provided in Section 9.4; (vi)
with respect to incorporation of the Trust to the extent and as provided in
Section 9.5; (vii) to the same extent as the stockholders of an Ohio business
corporation as to whether or not 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; and (viii) with respect to such additional
matters relating to the Trust as may be required by the Declaration, the Bylaws,
the 1940 Act or any registration of the Trust with the Commission (or any
successor agency), or as the Trustees may consider necessary or desirable.

      Except as otherwise provided in the Declaration or as required by the 1940
Act or other applicable law, and subject to applicable quorum requirements,
matters voted on by Shareholders must be approved by the affirmative vote of the
holders of a majority of the Shares voting at any meeting of Shareholders and
Trustees must be elected by a plurality of the Shares voting, or by an
instrument in writing, without a meeting, signed by a majority of the Trustees
and consented to by the holders of a majority of Shares outstanding and entitled
to vote, or by such other vote as may be


                                       17
<PAGE>   21

established by the Trustees with respect to any Series or Class of Shares,
provided that the election of Trustees (after the election by the initial sole
Shareholder) must be approved by the Shareholders at a meeting of Shareholders.

      Each whole Share shall be entitled to one vote as to any matter on which
it is entitled to vote and each fractional Share shall be entitled to
proportionate fractional vote, except that Shares held in the treasury of the
Trust shall not be voted, that on matters relating to the Trust and governed by
specific voting requirements in the 1940 Act shall be voted in accordance with
the 1940 Act and that the Trustees may, in conjunction with the establishment of
any Series of Shares, establish conditions under which the several Series shall
have separate voting rights or no voting rights. There shall be no cumulative
voting in the election of Trustees. Until Shares are issued, the Trustees may
exercise all rights of Shareholders and may take any action required by law, the
Declaration or the Bylaws to be taken by Shareholders. The Bylaws may include
further provisions for Shareholders' votes and meetings and related matters.

      Section 6.11. Investments in Trust. The Trustees may accept investments in
the Trust from such persons and on such terms and for such consideration, not
inconsistent with the provisions of the 1940 Act, as they from time to time
authorize. The Trustees may authorize any Distributor, Custodian, Transfer Agent
or other Person to accept orders for the purchase of Shares that conform to such
authorized terms and to reject any purchase orders for Shares whether or not
conforming to such authorized terms.

      Section 6.12. Series or Class Designation. The Trustees, in their
discretion, may authorize the issuance of Shares of multiple Series or Classes,
and the different Series or Classes shall be established and designated, and the
variations in the relative rights and preferences as between the different
Series or Classes shall be fixed and determined by the Trustees, provided, that
all Shares shall be identical except that there may be variations so fixed and
determined between different Series as to investment objective, purchase price,
right of redemption and the price, terms and manner of redemption, special and
relative rights as to dividends and on liquidation, conversion rights,
conditions under which the several Series shall have separate voting rights or
no voting rights, and such other matters, as the Trustees deem appropriate. All
references to Shares in the Declaration shall be deemed to be shares of any or
all Series as the context may require.

      If the Trustees shall authorize the issuance of Shares of the Trust with
multiple Series or Classes, the following provisions shall be applicable:

      (a) The number of authorized shares and the number of shares of each
      Series or Class that may be issued shall be unlimited. The Trustees may
      classify or reclassify any unissued Shares or any Shares previously issued
      and reacquired of any Series or Class into one or more other Series, or
      one or more other Classes that may be established and designated from time
      to time. The Trustees may hold as treasury shares (of the same or some
      other Series or Class), reissue for such consideration and on such terms
      as they may determine, or cancel any Shares of any Series or Class
      reacquired by the Trust at their discretion from time to time.


                                       18
<PAGE>   22

      (b) The power of the Trustees to invest and reinvest the Trust Property
      shall be governed by Section 3.2 of this Declaration with respect to the
      existing Series or Classes which represents the interests in the assets of
      the Trust immediately prior to the establishment of any additional Series
      or Classes and the power of the Trustees to invest and reinvest assets
      applicable to any such additional Series or Classes shall be as set forth
      in the instrument of the Trustees establishing such Series or Classes
      which is hereinafter described.

      (c) All consideration received by the Trust for the issue or sale of
      Shares of a particular Series, together with all assets in which such
      consideration is invested or reinvested, all income, earnings, profits and
      proceeds thereof, 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
      irrevocably belong to that Series for all purposes, subject only to the
      rights of creditors of such Series, and shall be so recorded upon the
      books of account of the Trust. In the event that there are any assets,
      income, earnings, profits, and proceeds thereof, funds, or payments which
      are not readily identifiable as belonging to any particular Series, the
      Trustees or their delegate shall allocate them among any one or more of
      the Series established and designated from time to time in such manner and
      on such basis as the Trustees, in their sole discretion, deem fair and
      equitable. Each such allocation by the Trustees shall be conclusive and
      binding upon the shareholders of all Series for all purposes. No holder of
      Shares of any Series shall have any claim on or right to any assets
      allocated or belonging to any other Series.

      (d) The assets belonging to each particular Series shall be charged with
      the liabilities of the Trust allocated to that Series and all expenses,
      costs, charges and reserves attributable to that Series which are not
      readily identifiable as belonging to any particular Class, and any general
      liabilities, expenses, costs, charges or reserves of the Trust which are
      not readily identifiable as belonging to any particular Series shall be
      allocated and charged by the Trustees or their delegatee to and among any
      one or more of the Series established and designated from time to time in
      such manner and on such basis as the Trustees, in their sole discretion,
      deem fair and equitable and no Series shall be liable to any person except
      for its allocated share. Each allocation of liabilities, expenses, costs,
      charges and reserves by the Trustees or their delegatee shall be
      conclusive and binding upon the Shareholders of all Series and Classes for
      all purposes. The Trustees shall have full discretion, to the extent not
      inconsistent with the 1940 Act, to determine which items shall be treated
      as income and which items as capital; and each such determination and
      allocation shall be conclusive and binding upon the Shareholders. The
      assets of a particular Series of the Trust shall, under no circumstances,
      be charged with liabilities, expenses, costs, charges and reserves
      attributable to any other Series thereof of the Trust. All Persons
      extending credit to, or contracting with or having any claim against a
      particular Series of the Trust shall look only to the assets of that
      particular Series for payment of such credit, contract or claim.

      (e) The power of the Trustees to pay dividends and make distributions
      shall be governed by Section 8.2 of this Trust with respect to the nine
      initial Series which represents the interests in the assets of the Trust
      immediately prior to the establishment of any additional Series. With
      respect to any other Series, dividends and distributions on Shares of a
      particular


                                       19
<PAGE>   23

      Series or Class may be paid or credited in such manner and with such
      frequency as the Trustees may determine, which may be daily or otherwise,
      pursuant to a standing resolution or resolutions adopted only once or with
      such frequency as the Trustees may determine, to the holders of Shares of
      that Series or Class, from such of the income and capital gains, accrued
      or realized, from the assets belonging to that Series, as the Trustees may
      determine, after providing for actual and accrued liabilities belonging to
      that Series or Class. All dividends and distributions on Shares of a
      particular Series or Class shall be distributed pro rate to the holders of
      that Series or Class in proportion to the number of Shares of that Series
      or Class held by such holders at the date and time of record established
      for the payment of such dividends or distributions.

      (f) Each Share of a Series of the Trust shall represent a beneficial
      interest in the net assets of such Series. Each holder of Shares of a
      Series or Class thereof shall be entitled to receive his pro rata Share of
      distributions of income and capital gains made with respect to such Series
      or Class net of liabilities, expenses, costs, charges and reserves
      belonging and allocated to such Series or Class. Upon redemption of his
      Shares or indemnification for liabilities incurred by reason of his being
      or having been a Shareholder of a Series, such Shareholder shall be paid
      solely out of the funds and property of such Series or Class of the Trust.
      Upon liquidation or termination of a Series or Class thereof of the Trust,
      a Shareholder of such Series or Class thereof shall be entitled to receive
      a pro rata Share of the net assets of such Series based on the net asset
      value of his Shares. A Shareholder of a particular Series of the Trust
      shall not be entitled to commence or participate in a derivative or class
      action on behalf of any other Series or the Shareholders of any other
      Series of the Trust.

      (g) All Shares of all Series shall have "equal voting rights" as provided
      in Section 18(i) of the 1940 Act, except as otherwise permitted or
      required by the 1940 Act. The holder of each of the Shares shall be
      entitled to one vote for each Share held. The Trustees shall have full
      power and authority to call meetings of the Shareholders of a particular
      Class or Classes of Shares or of one or more particular Series of Shares,
      or otherwise call for the action of such Shareholders on any particular
      matter.

      (h) Except as otherwise provided in this Article VI, the Trustees shall
      have full power and authority to determine the designations, preferences,
      privileges, sales charges, purchase prices, assets, liabilities, expenses,
      costs, charges and reserves belonging or allocated thereto, limitations
      and rights, including without limitation voting, dividend, distribution
      and liquidation rights, of each Series and Class of Shares. Subject to any
      applicable requirements of the 1940 Act, the Trustees shall have the
      authority to provide that the Shares of one Class shall be automatically
      converted into Shares of another Class of the same Series or that the
      holders of Shares of any Series or Class shall have the right to convert
      or exchange such Shares into Shares of one or more other Series or Classes
      of Shares, all in accordance with such requirements, conditions and
      procedures as may be established by the Trustees.

      (i) The establishment and designation of any Series or Class of shares
      shall be effective upon the execution by a majority of the then Trustees
      of an instrument setting forth such establishment and designation and the
      relative rights and preferences of such Series, or as


                                       20
<PAGE>   24

      otherwise provided in such instrument. At any time that there are no
      shares outstanding of any particular Series or Class previously
      established and designated, the Trustees may, by an instrument executed by
      a majority of their number, abolish that Series or Class and the
      establishment and designation thereof.

      Section 6.13. Meetings of Shareholders. A meeting of the Shareholders
shall be held at such times, on such day and at such hour as the Trustees may
from time to time determine, or at the written request of the holder or holders
of ten percent (10%) or more of the total number of Shares then issued and
outstanding of the Trust entitled to vote as such meeting or as required by law.
Any such request shall state the purpose of the proposed meeting. The meeting
shall be held either at the principal office of the Trust, or at such other
place as may be designated by the Trustees, for such purposes as may be
specified by the Trustees.

      Section 6.14. Inspection of Records. The records of the Trust shall be
open to inspection by Shareholders to the same extent as is permitted
stockholders of an Ohio corporation organized under Chapter 1701, Ohio Revised
Code.

      Section 6.15. Additional Provisions. The Bylaws may include further
provisions for Shareholders' votes and meetings and related matters not
inconsistent with the provisions hereof.

                                   ARTICLE VII

                                   REDEMPTIONS

      Section 7.1. Redemption of Shares. All Shares of the Trust shall be
redeemable, at the redemption price determined in the manner set out in this
Declaration. The Trustees shall have full power and authority to vary and change
the right of redemption applicable to the various Series and Classes of Shares.
Redeemed or repurchased Shares may be resold by the Trust.

      The Trust shall redeem the Shares at the price determined as hereinafter
set forth, upon the appropriately verified written application of the record
holder thereof (or upon such other form of request as the Trustees may
determine) at such office or agency as may be designated from time to time for
that purpose by the Trustees. The Trustees may from time to time specify
additional conditions, not inconsistent with the 1940 Act, regarding the
redemption of Shares in the Trust's then effective registration statement or
prospectus under the Securities Act of 1933.

      Section 7.2. Price. Shares will be redeemed at their net asset value
determined as set forth in Section 8.1 hereof as of such time as the Trustees
shall have theretofore prescribed by resolution. In the absence of such
resolution, the redemption price of Shares deposited shall be the net asset
value of such Shares next determined as set forth in Section 8.1 hereof after
receipt of such application.

      Section 7.3. Payment. Payment for such Shares shall be made in cash or in
property out of the assets of the relevant Series of the Trust to the
Shareholder of record at such time and in the manner, not inconsistent with the
1940 Act or other applicable laws, as may be specified from time


                                       21
<PAGE>   25

to time in the Trust's then effective registration statement or prospectus under
the Securities Act of 1933, subject to the provisions of Section 7.3 hereof.
Notwithstanding the foregoing, the Trust or its delegate may withhold from such
redemption proceeds any amount arising (i) from a liability of the redeeming
Shareholder to the Trust, or (ii) in connection with any federal or state tax
withholding requirements.

      Section 7.4. Effect of Suspension of Determination of Net Asset Value. If,
pursuant to Section 7.8 hereof, the Trustees shall declare a suspension of the
determination of net asset value with respect to Shares of the Trust or of any
Series or Class thereof, the rights of Shareholders (including those who shall
have applied for redemption pursuant to Section 7.1 hereof but who shall not yet
have received payment) to have Shares redeemed and paid for by the Trust shall
be suspended until the termination of such suspension is declared. Any record
holder who shall have his redemption right so suspended may, during the period
of such suspension, by appropriate written notice of revocation at the office or
agency where application was made, revoke any application for redemption not
honored and withdraw any certificates on deposit. The redemption price of Shares
for which redemption applications have not been revoked shall be the net asset
value of such Shares next determined as set forth in Section 8.1 after the
termination of such suspension, and payment shall be made within seven (7) days
after the date upon which the application was made plus the period after such
application during which the determination of net asset value was suspended.

      Section 7.5. Repurchase by Agreement. The Trust may repurchase Shares
directly, or through the Distributor or another agent designated for the
purpose, by agreement with the owner thereof at a price not exceeding the net
asset value per Share determined as of the time when the purchase or contract of
purchase is made or the net asset value as of any time which may be later
determined pursuant to Section 8.1 hereof, provided payment is not made for the
Shares prior to the time as of which such net asset value is determined.

      Section 7.6. Redemption of Shareholder's Interest. The Trust shall have
the right at any time without prior notice to the Shareholder to redeem Shares
of any Shareholder for their then current net asset value per Share if the
aggregate net asset value of such Shares is less than the minimum amount
established by the Trustees from time to time, subject to such terms and
conditions as the Trustees may approve, and subject to the Trust's giving
general notice to all Shareholders of its intention to avail itself of such
right, either by publication in the Trust's prospectus, if any, or by such other
means as the Trustees may determine.

      Section 7.7. Reductions in Number of Outstanding Shares Pursuant to Net
Asset Value Formula. The Trust may also reduce the number of outstanding Shares
pursuant to the provisions of Section 8.2.

      Section 7.8. Suspension of Right of Redemption. The Trust may declare a
suspension of the right of redemption or postpone the date of payment or
redemption for the whole or any part of any period (i) during which the New York
Stock Exchange is closed other than customary weekend and holiday closings; (ii)
during which trading on the New York Stock Exchange is restricted; (iii) during
which an emergency exists as a result of which disposal by the Trust of
securities owned by it is not reasonably practicable or it is not reasonably
practicable for the Trust fairly to determine the


                                       22
<PAGE>   26

value of its net assets; or (iv) during any other period when the Commission may
for the protection of security holders of the Trust by order permit suspension
of the right of redemption or postponement of the date of payment or redemption;
provided that applicable rules and regulations of the Commission shall govern as
to whether the conditions prescribed in (ii), (iii), or (iv) exist. Such
suspension shall take effect at such time as the Trust shall specify, but not
later than the close of business on the business day next following the
declaration of suspension, and thereafter there shall be no right of redemption
or payment on redemption until the Trust shall declare the suspension at an end,
except that the suspension shall terminate in any event on the first day on
which said stock exchange shall have reopened or the period specified in (ii) or
(iii) shall have expired (as to which, in the absence of an official ruling by
the Commission, the determination of the Trust shall be conclusive). In the case
of a 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.

      Section 7.9. Redemption of Shares; Disclosure of Holding. If the Trustees
shall, at any time and in good faith, be of the opinion that direct or indirect
ownership of Shares or other securities of the Trust has or may become
concentrated in any Person to an extent which would disqualify the Trust as a
regulated investment company under the Internal Revenue Code, then the Trustees
shall have the power by lot or other means deemed equitable by them (i) to call
for redemption by any such Person of a number, or principal amount, of Shares or
other securities of the Trust sufficient to maintain or bring the direct or
indirect ownership of Shares or other securities of the Trust into conformity
with the requirements for such qualification; and (ii) to refuse to transfer or
issue Shares or other securities of the Trust to any Person whose acquisition of
the Shares or other securities of the Trust in question would result in such
disqualification. The redemption shall be effected at the redemption price and
in the manner provided in Section 7.1.

      The holders of Shares or other securities of the Trust shall upon demand
disclose to the Trustees in writing such information with respect to direct and
indirect ownership of Shares or other securities of the Trust as the Trustees
deem necessary to comply with the provisions of the Internal Revenue Code, or to
comply with the requirements of any other authority.

                                  ARTICLE VIII

                        DETERMINATION OF NET ASSET VALUE
                          NET INCOME AND DISTRIBUTIONS

      Section 8.1. Net Asset Value. For all purposes under this Declaration of
Trust, the net asset value of any Series or Class shall be determined by at
least once on each business day, as of the close of the New York Stock Exchange
or as of such other time or times as the Trustees shall determine.

      The value of the assets of any Series of the Trust shall include the
appraisal of the securities allocated to such Series, such appraisal to be on
the basis of the amortized cost of money market securities or market value in
the case of other securities, or, consistent with the rules and regulations of
the Commission, by such other method as shall be deemed to reflect the fair
value thereof, determined in good faith by or under the direction of the
Trustees, together with all the other assets


                                       23
<PAGE>   27

belonging to such Series. From the total value of said assets, there shall be
deducted all indebtedness, interest, taxes, payable or accrued, including
estimated taxes on unrealized book profits, expenses and management charges
accrued to the appraisal date, net income determined and declared as a
distribution and all other items in the nature of liabilities attributable to
such Series which shall be deemed appropriate. The net asset value per Share of
the Shares of any Series shall be the quotient obtained by dividing the
resulting amount by the total number of Shares of that Series outstanding. The
power and duty to make the daily calculations may be delegated by the Trustees
to the Investment Adviser, the Custodian, the Transfer Agent or such other
Person as the Trustees by resolution may determine. The Trustees may suspend the
daily determination of net asset value to the extent permitted by the 1940 Act.

      Section 8.2. Distributions to Shareholders. The Trustees shall from time
to time distribute ratably among the Shareholders of the Trust or of a Series or
a Class thereof such proportion of the net profits, surplus (including paid-in
surplus), capital, or assets held by the Trustees as they may deem proper. Such
distribution may be made in cash or property (including without limitation any
type of obligations of the Trust or any assets thereof), and the Trustees may
distribute ratably among the Shareholders, or such Series or Class, additional
Shares issuable hereunder in such manner, at such times, and on such terms as
the Trustees may deem proper. Such distributions may be among the Shareholders
of record at the time of declaring a distribution or among the Shareholders of
record at such later date as the Trustees shall determine. The Trustees may in
their discretion determine that, solely for the purposes of such distributions,
outstanding Shares shall exclude Shares for which orders have been placed
subsequent to a specified time. The Trustees may always retain from the net
profits such amount as they may deem necessary to pay the debts or expenses of
the Series or Class or to meet obligations of the Series or Class, or as they
may deem desirable to use in the conduct of its affairs or to retain for future
requirements or extensions of the business. The Trustees may adopt and offer to
Shareholders such dividend reinvestment plans, cash dividend payout plans or
related plans as the Trustees shall deem appropriate.

      Inasmuch as the computation of net income and gains for Federal income tax
purposes may vary from the computation thereof on the books, the above
provisions shall be interpreted to give the Trustees the power in their
discretion to distribute for any fiscal year as ordinary dividends and as
capital gains distributions, respectively, additional amounts sufficient to
enable the Trust or the Series to avoid or reduce liability for taxes.

      Section 8.3. Determination of Net Income. The term "net income" with
respect to a Series or Class of shares is hereby defined as the gross earnings
of the Series or Class, excluding gains on sales of securities and stock
dividends received, less the expenses of the Trust allocated to the Series or
Class by the Trustees in such manner as they determine to be fair and equitable
or otherwise chargeable to the Series or Class. The expenses shall include (1)
taxes attributable to the income of the Trust exclusive of gains on sales, and
(2) other charges properly deductible for the maintenance and administration of
the Trust; but there shall not be deducted from gross or net income any losses
on securities, realized or unrealized. The Trustees shall otherwise have full
discretion to determine which items shall be treated as income and which items
as capital and their determination shall be binding upon the Shareholders.

      Section 8.4. Power to Modify Foregoing Procedures. Notwithstanding any of
the foregoing provisions of this Article VIII, the Trustees may prescribe, in
their absolute discretion, such other bases and times for determining the per
Share net asset value of the Shares or net income, or the declaration and
payment of dividends and distributions as they may deem necessary or desirable.
Without limiting the generality of the foregoing, the Trustees may establish
additional Series or Classes of Shares in accordance with Section 6.12, and
declare dividends thereon in such manner as they shall determine.

                                   ARTICLE IX

                         DURATION; TERMINATION OF TRUST
                            AMENDMENT; MERGERS; ETC.

      Section 9.1. Duration. The Trust shall continue without limitation of time
but subject to the provisions of this Article IX.

      Section 9.2. Termination of Trust.

      (a) The Trust or any Series or Class of the Trust may  be terminated:

            (i) by the affirmative vote of the holders of a majority of the
            Shares voting at any meeting of Shareholders, or (ii) by an
            instrument in writing, without a meeting, signed by a majority of
            the Trustees and consented to by the holders of a majority of Shares
            outstanding and entitled to vote, or by such other vote as may be
            established by the Trustees with respect to any Series or Class of
            Shares.

      Upon the termination of the Trust or any one or more Series or Class:

            (i) The Trust or the Series or Class, as applicable, shall carry on
            no business except for the purpose of winding up its affairs or the
            affairs of such Series or Class and that required by the 1940 Act.

            (ii) The Trustees shall proceed to wind up the affairs of the Trust
            and/or the Series or Class and all of the powers of the Trustees
            under this Declaration shall continue until the affairs of the Trust
            or any Series or Class shall have been wound up, including the power
            to fulfill or discharge the contracts of the Trust or the Series of
            the Trust, collect its assets, sell, convey, assign, exchange,
            transfer or otherwise dispose of all or any part of the remaining
            Trust Property to one or more persons at public or private sale for
            consideration which may consist in whole or in part of cash,
            securities or other property of any kind, discharge or pay its
            liabilities, and to do all other acts appropriate to liquidate its
            business; provided that any sale, conveyance, assignment, exchange,
            transfer or other disposition of all or substantially all the Trust
            Property shall require Shareholder approval in accordance with
            Section 9.4 hereof.


                                       25
<PAGE>   29

            (iii) After paying or adequately providing for the payment of all
            liabilities, and upon receipt of such releases, indemnities and
            refunding agreements, as they deem necessary for their protection,
            the Trustees may distribute the remaining Trust Property, in cash or
            in kind or partly each, among the Shareholders according to their
            respective rights.

      (b) After termination of the Trust or any Series or Class of the Trust and
      distribution to the Shareholders as herein provided, a majority of the
      Trustees shall execute and lodge among the records of the Trust an
      instrument in writing setting forth the fact of such termination, and the
      Trustees shall thereupon be discharged from all further liabilities and
      duties hereunder, and the rights and interests of all Shareholders thereof
      shall thereupon cease with regard to the Trust, Series or Class, as
      applicable.

      Section 9.3. Amendment Procedure.

      (a) This Declaration may be amended by a vote of the Shareholders holding
      a majority of the Shares voting, or by any instrument in writing, without
      a meeting, signed by a majority of the Trustees and consented to by the
      holders of not less than a majority of the Shares outstanding and entitled
      to vote. Amendments shall be effective upon the taking of action as
      provided in this section or at such later time as shall be specified in
      the applicable vote or instrument. The Trustees may also amend this
      Declaration without the vote or consent of Shareholders to designate
      Series or Classes in accordance with Section 6.12 hereof, to change the
      name of the Trust or any Series or Class thereof, to supply any omission,
      to cure, correct or supplement any ambiguous, defective or inconsistent
      provision hereof, or if they deem it necessary to conform this Declaration
      to the requirements of applicable federal laws or regulations or the
      requirements of the regulated investment company provisions of the
      Internal Revenue Code, or to make any other changes in the Declaration
      which do not materially adversely affect the rights of Shareholders
      hereunder, but the Trustees shall not be liable for failing to do so. In
      addition amendment of this Declaration of Trust as it may affect any one
      or more Series may be effected by vote of the Trustees at any time when
      the Trust has no outstanding Shares or Shareholders of such Series.

      (b) No amendment may be made under this Section 9.3 which would change any
      rights with respect to any Shares of the Trust by reducing the amount
      payable thereon upon liquidation of the Trust or by diminishing or
      eliminating any voting rights pertaining thereto, except with the vote or
      consent of the holders of two-thirds of the Shares outstanding and
      entitled to vote, or by such other vote as may be established by the
      Trustees with respect to any Series of Shares. Nothing contained in this
      Declaration shall permit the amendment of this Declaration to impair the
      exemption from personal liability of the Shareholders, Trustees, officers,
      employees and agents of the Trust or to permit assessments upon
      Shareholders without the express consent of each Shareholder or Trustee
      involved.

      (c) A certificate signed by a majority of the Trustees setting forth an
      amendment and reciting that it was duly adopted by the Shareholders or by
      the Trustees as aforesaid or a copy


                                       26
<PAGE>   30

      of the Declaration, as amended, and executed by a majority of the
      Trustees, shall be conclusive evidence of such amendment when lodged among
      the records of the Trust.

      Notwithstanding any other provision 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 become effective, or
at any time there are no longer outstanding any Shares of the Trust, this
Declaration may be terminated or amended in any respect by the affirmative vote
of a majority of the Trustees or by an instrument signed by a majority of the
Trustees.

      Section 9.4. Merger, Consolidation and Sale or Disposition of Assets. The
Trustees may sell, convey and transfer the assets of the Trust, or the assets
belonging to one or more or all Series, to another trust, partnership,
association or corporation organized under the laws of any state of the United
States, or to the Trust to be held as assets belonging to one or more Series of
the Trust, in exchange for cash, shares or other securities (including, in the
case of a transfer to another Series of the Trust, Shares of such other Series)
with such transfer being made subject to, or with the assumption by the
transferee, of the liabilities belonging to each Series the assets of which are
so transferred; provided, however, that no assets belonging to the Trust or to
any particular Series shall be so transferred unless the terms of such transfer
shall have first been approved at a meeting called for that purpose by the
affirmative vote of Shareholders holding a majority of the voting power of Trust
or of each Series affected. Following such transfer, the Trustees shall
distribute such cash, shares or other securities (giving due effect to the
assets and liabilities belonging to and any other differences among the various
Series the assets belonging to which have so been transferred) among the
Shareholders of the Series the assets belonging to which have been so
transferred; and if all the assets of the Series or Trust have been so
transferred, the Series or Trust, as the case may be, shall be terminated.

      The Trust or any Series thereof may be a party, with one or more entities
(including another Series) to an agreement of merger or consolidation; provided,
however, that any such agreement of merger or consolidation shall be approved by
the Trustees, and by the affirmative vote of Shareholders holding a majority of
the voting power of the Trust or of each Series affected.

      Section 9.5. Incorporation. With the approval of the holders of a majority
of the Shares outstanding and voting, or by such other vote as may be
established by the Trustees with respect to any Series of Shares [(if
Shareholder approval is required)], the Trustees may cause to be organized or
assist in organizing a corporation or corporations under the laws of any
jurisdiction or any other trust, partnership, association or other organization
to take over all of the Trust Property or to carry on any business in which the
Trust shall directly or indirectly have any interest, and to sell, convey and
transfer the Trust Property to any such corporation, trust, association or
organization in exchange for the shares or securities thereof and assumption of
liabilities of the Trust or otherwise, and to lend money to, subscribe for the
shares or securities of, and enter into any contracts with any such corporation,
trust, partnership, association or organization in which the Trust holds or is
about to acquire shares or any other interest. The Trustees may also cause a
merger or consolidation between the Trust or any successor thereto and any such
corporation, trust, partnership, association or other organization if and to the
extent permitted by law, as provided under the law then in effect.

      Section 9.6. Absence of Dissenters' Rights. No shareholder shall be
entitled, as a matter of right, to relief as a dissenting shareholder in respect
of any proposal or action involving the Trust.

into a single instrument all of the provisions of the Declaration which are then
in effect and operative, may be executed from time to time by a majority of the
Trustees and shall, upon filing with the Secretary of the of Ohio, be conclusive
evidence of all amendments contained herein and may thereafter be referred to in
lieu of the original Declaration and the various amendments thereto.

      Section 10.2. Governing Law. This Declaration is executed by the Trustees
and delivered with reference to the laws of the of Ohio, and the rights of all
parties and the validity and construction of every provision hereof shall be
subject to and construed according to the laws of said State.

      Section 10.3. Counterparts. This Declaration may be simultaneously
executed in several counterparts, each of which shall be deemed to be an
original, and such counterparts, together, shall constitute one and the same
instrument, which shall sufficiently evidenced by any such original counterpart.

      Section 10.4. Reliance by Third Parties. Any certificate executed by an
individual who, according to the records of the Trust appears to be a Trustee
hereunder, certifying to: (a) the number or identity of Trustees or
Shareholders, (b) the due authorization of the execution of any instrument or
writing, (c) the form of any vote passed at a meeting of Trustees or
Shareholders, (d) the fact that the number of Trustees or Shareholders present
at any meeting or executing any written instrument satisfies the requirements of
this Declaration, (e) the form of any Bylaws adopted by or the identity of any
officers elected by the Trustees, or (f) the existence of any fact or facts
which in any manner relate to the affairs of the Trust, shall be conclusive
evidence as to the matters so certified in favor of any Person dealing with the
Trustees and their successors.

      Section 10.5. Provisions in Conflict with Law or Regulations.

      shall determine, with the advice of counsel, that any of such provisions
      is in conflict with the 1940 Act, the regulated investment company
      provisions of the Internal Revenue Code or with other

                                       28
<PAGE>   32

      applicable laws and regulations, the conflicting provisions shall be
      deemed never to have constituted a part of the Declaration; provided,
      however, that such determination shall not affect any of the remaining
      provisions of the Declaration or render invalid or improper any action
      taken or omitted prior to such determination.

      (b) If any provision of the Declaration shall be held invalid or
      unenforceable in any jurisdiction, such invalidity or unenforceability
      shall attach only to such provision in such jurisdiction and shall not in
      any manner affect such provision in any other jurisdiction or any other
      provision of the Declaration in any jurisdiction.

      Section 10.6. Index and Heading for Reference Only. The Index and heading
preceding the text, articles and sections hereof have been inserted for
convenience and reference only and shall not be construed to affect the meaning,
construction or effect of this Declaration.

actions required by the 1940 Act to be taken by vote of the Shareholders of an
individual series, a quorum shall consist of a majority of all votes
attributable to the outstanding Shares of such individual series entitled to
vote thereon, and that at any meeting at which the only action 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 of the Trust, a quorum shall consist of a
majority of all votes attributable to the outstanding Shares of the series so
affected; and provided, further, that reasonable adjournments of such meeting
until a quorum is obtained may be made by a vote attributable so the Shares
present in person or by proxy. A majority of the votes shall decide any question
or a plurality shall elect a Trustee, subject to any applicable requirements of
law or of this Bylaws or the Declaration of Trust; provided, however, that when
any provisions of law or of this Bylaws requires the holders of Shares of any
particular series to vote by series and not in the aggregate with respect to a
matter, then a majority of all votes attributable to the outstanding Shares of
that series shall decide such matter insofar as that particular series shall be
concerned.

      Section 4. Record Date for Meetings. For the purpose of determining the
Shareholders who are entitled to notice of and to vote at any meeting, or to
participate in any distribution, or for the purpose of any other action, the
Trustees may from time to time close the transfer books for such period, not
exceeding thirty (30) days, as the Trustees may determine; or without closing
the transfer books the Trustees may fix a date not more than sixty (60) days
prior to the date of any meeting of Shareholders or distribution or other action
as a record date for the determinations of the persons to be treated as
Shareholders of record for such purposes, except for dividend payments which
shall be governed by the Declaration. Only Shareholders of record at the close
of business on the record date will be entitled to notice of and to vote at any
meeting.

      Section 5. Proxies. At any meeting of Shareholders, any holder of Shares
entitled to vote thereat may vote by proxy, provided that no proxy shall be
voted at any meeting unless it shall have been placed on file with the
Secretary, or with such other officer or agent of the Trust as the Trustees may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of a majority of the Trustees, proxies may be solicited
in the name of one or more Trustees or one or more of the officers of the Trust.
Only Shareholders of record shall be entitled to vote. Each full Share shall be
entitled to one vote and fractional Shares shall be entitled to a vote of such
fraction. When any share is held jointly by several persons, any one of them may
vote at any meeting in person or by proxy in respect of such Share, but if more
than one of them shall be present at such meeting in person or by proxy, and
such joint owners or their proxies so present disagree as to any vote to be
cast, such vote shall not be received in respect of such Share. A proxy
purporting to be executed by or on behalf of a Shareholder shall be deemed valid
unless challenged at or prior to its exercise, and the burden of proving
invalidity shall rest on the challenger. If the holder of any such Share is a
minor or a person of unsound mind, and subject to guardianship or to the legal
control of
<PAGE>   4

any other person as regards the change or management of such Share, he may vote
by his guardian or such other person appointed or having such control, and such
vote may be given in person or by proxy.

      To the extent that Series are included as underlying investment options in
variable contracts issued by Nationwide Life Insurance Company or Nationwide
Life and Annuity Insurance Company (collectively, "Nationwide"), Nationwide will
vote the shares of each Series at any meeting in accordance with timely
instructions under the variable contracts issued by Nationwide. Nationwide will
vote shares attributable to variable contracts as to which no voting
instructions are received in proportion (for, against or abstain) to those for
which timely instructions are received. If a proxy is received that does not
specify a choice, Nationwide will consider its timely receipt as an instruction
to vote in favor the proposal to which it relates. In certain circumstances,
Nationwide has the right to disregard voting instructions from certain variable
contract owners. Variable contract owners may revoke previously submitted voting
instructions given to Nationwide at any time prior to any meeting by either
submitting to the Trust a subsequently dated proxy, delivering to the Trust a
written notice of revocation or otherwise giving notice of revocation in open
meeting, in all cases prior to the exercise of the authority granted in the
proxy.

      Section 6. Inspection of Records. The records of the Trust shall be open
to inspection by Shareholders to the same extent as is permitted shareholders of
an Ohio business corporation or as required by the 1940 Act.

      Section 7. Action Without a Meeting. Any action which may be taken by
Shareholders may be taken without a meeting if a majority of Shareholders
entitled to vote on the matter (or such larger proportion thereof as shall be
required by law, the Declaration or these Bylaws for approval of such matter)
consent to the action in writing and the written consents are 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.

                                    TRUSTEES

      Section 1. Meetings of the Trustees. The Trustees may in their discretion
provide for regular or stated meetings of the Trustees. Notice of regular or
stated meetings need not be given. Meetings of the Trustees other than by
regular or stated meetings shall be held whenever called by the Chairman, or by
any one of the Trustees, at the time being in office. Notice of the time and
place of each meeting other than regular or stated meetings shall be given by
the Secretary or an Assistant Secretary or by the officer or Trustee calling the
meeting and shall be mailed to each Trustee at least two days before the
meeting, or shall be telegraphed, cabled, or wirelessed to each Trustee at his
business address, or personally delivered to him at least one day before the
meeting. Such notice may, however, be waived by an Trustee. Notice of a meeting
need not be given to any Trustee if a written waiver of notice, executed by him
before or after the meeting, is filed with the records of the meeting, or to any
Trustee who attends the meeting without protesting prior thereto or at its
commencement the lack of notice to him. A notice or waiver of notice need not
specify the purpose of any meeting. The Trustees may meet by means of a
telephone conference circuit or similar
<PAGE>   5

communications equipment by means of which all persons participating in the
meeting can hear each other, which telephone conference meeting shall be deemed
to have been held at a place designated by the Trustees at the meeting.
Participation in a telephone conference meeting shall constitute presence in
person at such meeting. Any action required or permitted to be taken at any
meeting of the Trustees may be taken by the Trustees without a meeting if all
the Trustees consent to the action in writing and the written consents are filed
with the records of the Trustees' meetings. Such consents shall be treated as a
vote for all purposes.

      Section 2. Quorum and Manner of Acting. A majority of the Trustees shall
be present in person at any regular or special meeting of the Trustees in order
to constitute a quorum for the transaction of business at such meeting and
(except as otherwise required by law, the Declaration or these Bylaws) the act
of a majority of the Trustees present at any such meeting, at which a quorum is
present, shall be the act of the Trustees. In the absence of a quorum, a
majority of the Trustees present may adjourn the meeting from time to time until
a quorum shall be present. Notice of an adjourned meeting need not be given.

                                    ARTICLE V

of the Trustees, which shall have the power to conduct the current and ordinary
business of the Trust while the Trustees are not in session, including the
purchase and sale of securities and the designation of securities to be
delivered upon redemption of Shares of the Trust, and such other powers of the
Trustees as the Trustees may, from time to time, delegate to them except those
powers which by law, the Declaration or these Bylaws they are prohibited from
delegating. The Trustees may also elect from their own number other Committees
from time to time, the number composing such Committees and powers conferred
upon the same (subject to the same limitations with respect to the Executive
Committee) and the term of membership on such Committees to be determined by the
Trustees. The Trustees may designate a chairman of any such Committee. In the
absence of such designation, the Committee may elect its own Chairman.

      Section 2. Meeting, Quorum and Manner of Acting. The Trustees may (1)
provide for stated meetings of any Committees, (2) specify the manner of calling
and notice required for special meetings of any Committee, (3) specify the
number of members of a Committee required to constitute a quorum and the number
of members of a Committee required to exercise specified powers delegated to
such Committee, (4) authorize the making of decisions to exercise specified
powers by written action of the requisite number of members of a Committee
without a meeting and (5) authorize the members of a Committee to meet by means
of a telephone conference circuit.

      The Executive Committee shall keep regular minutes of its meetings and
records of decisions taken without a meeting and cause them to be recorded in a
book designated for that purpose and kept in the offices of the Trust.
<PAGE>   6

      Section 3. Advisory Board. The Trustees may appoint an Advisory Board to
consist in the first instance of not less than three (3) members. Members of
such Advisory Board shall not be Trustees or officers and need not be
Shareholders. Members of this Board shall hold office for such period as the
Trustees may by resolution provide. Any member of such Board may resign
therefrom by a written instrument signed by him which shall take effect upon
delivery to the Trustees. The Advisory Board shall have no legal powers and
shall not perform the functions of Trustees in any manner, said Board being
intended merely to act in an advisory capacity. Such Advisory Board shall meet
at such times and upon such notice as the Trustees may by resolution provide.

                                   ARTICLE VI

of the Trustees. Any officer or agent appointed by any officer or committee may
be removed with or without cause by such appointing officer or committee.

      Section 4. Powers and Duties of the Chairman. The Chairman may call
meetings of the Trustees and of any Committee thereof when he deems it necessary
and shall preside at all meetings of the Shareholders. Subject to the control of

spheres, as provided by the Trustees, he shall at all times exercise a general
supervision and direction over the affairs of the Trust. He shall have the power
to employ attorneys and counsel for the Trust and to employ such subordinate
officers, agents, clerks and employees as he may find necessary to transact the
business of the Trust. He shall also have the power to grant, issue, execute or
sign such powers of attorney, proxies or other documents as may be deemed
advisable or necessary in furtherance of the interest of the Trust. The Chairman
shall have such other powers and duties as, from time to time, may be conferred
upon or assigned to him by the Trustees.

      Section 5. Powers and Duties of Vice Chairman. In the absence or
disability of the Chairman, the Vice Chairman or, if there be more than one Vice
Chairman, any Vice Chairman designated by the Trustees shall perform all the

                          INVESTMENT ADVISORY AGREEMENT

      THIS AGREEMENT is made and entered into on this ____ day of ____________,
1998, between NATIONWIDE INVESTING FOUNDATION III (the "Trust"), an Ohio
business trust, and NATIONWIDE ADVISORY SERVICES, INC. (the "Adviser"), an Ohio
corporation registered under the Investment Advisers Act of 1940 (the "Advisers
Act").

                              W I T N E S S E T H :

      WHEREAS, the Trust is registered with the Securities and Exchange
Commission (the "SEC") as an open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act");

      WHEREAS, the Trust desires to retain the Adviser to furnish certain
investment advisory services, as described herein, with respect to certain of
the series of the Trust, all as now are or may be hereafter listed on Exhibit A
to this Agreement (each, a "Fund"); and

      WHEREAS, the Adviser represents that it is willing and possesses legal
authority to render such services subject to the terms and conditions set forth
in this Agreement.

      NOW, THEREFORE, the Trust and the Adviser do mutually agree and promise as
follows:

      1. Appointment as Adviser. The Trust hereby appoints the Adviser to act as
investment adviser to each Fund subject to the terms and conditions set forth in
this Agreement. The Adviser hereby accepts such appointment and agrees to
furnish the services hereinafter described for the compensation provided for in
this Agreement.

      2. Duties of Adviser.

            (a) Investment Management Services. (1) Subject to the supervision
      of the Trust's Board of Trustees (and except as otherwise permitted under
      the terms of any exemptive relief obtained by the Adviser from the
      Securities and Exchange Commission, or by rule or regulation), the Adviser
      will provide, or arrange for the provision of, a continuous investment
      program and overall investment strategies for each Fund, including
      investment research and management with respect to all securities and
      investments and cash equivalents in each Fund. The Adviser will determine,
      or arrange for others to determine, from time to time what securities and
      other investments will be purchased, retained or sold by each Fund and
      will implement, or arrange for others to implement, such determinations
      through the placement, in the name of a Fund, of orders for the execution
      of portfolio transactions with or through such brokers or dealers as may
      be so selected. The Adviser will provide, or arrange for the provision of,
      the services under this Agreement in accordance with the stated investment
      policies and restrictions of each Fund as set forth in that Fund's current
      prospectus and statement of additional information as currently in effect
      and as supplemented or amended
<PAGE>   2

      from time to time (collectively referred to hereinafter as the
      "Prospectus") and subject to the directions of the Trust's Board of
      Trustees.

            (2) Subject to the provisions of this Agreement and the 1940 Act and
      any exemptions thereto, the Adviser is authorized to appoint one or more
      qualified subadvisers (each a "Subadviser") to provide each Fund with
      certain services required by this Agreement. Each Subadviser shall have
      such investment discretion and shall make all determinations with respect
      to the investment of a Fund's assets as shall be assigned to that
      Subadviser by the Adviser and the purchase and sale of portfolio
      securities with respect to those assets and shall take such steps as may
      be necessary to implement its decisions. The Adviser shall not be
      responsible or liable for the investment merits of any decision by a
      Subadviser to purchase, hold, or sell a security for a Fund.

            (3) Subject to the supervision and direction of the Trustees, the
      Adviser shall (i) have overall supervisory responsibility for the general
      management and investment of a Fund's assets; (ii) determine the
      allocation of assets among the Subadvisers, if any; and (iii) have full
      investment discretion to make all determinations with respect to the
      investment of Fund assets not otherwise assigned to a Subadviser.

            (4) The Adviser shall research and evaluate each Subadviser, if any,
      including (i) performing initial due diligence on prospective Subadvisers
      and monitoring each Subadviser's ongoing performance; (ii) communicating
      performance expectations and evaluations to the Subadvisers; and (iii)
      recommending to the Trust's Board of Trustees whether a Subadviser's
      contract should be renewed, modified or terminated. The Adviser shall also
      recommend changes or additions to the Subadvisers and shall compensate the
      Subadvisers.

            (5) The Adviser shall provide to the Trust's Board of Trustees such
      periodic reports concerning a Fund's business and investments as the Board
      of Trustees shall reasonably request.

            (b) Compliance with Applicable Laws and Governing Documents. In the
      performance of its duties and obligations under this Agreement, the
      Adviser shall act in conformity with the Trust's Declaration of Trust and
      By-Laws and the Prospectus and with the instructions and directions
      received from the Trustees of the Trust and will conform to and comply
      with the requirements of the 1940 Act, the Internal Revenue Code of 1986,
      as amended (the "Code") (including the requirements for qualification as a
      regulated investment company) and all other applicable federal and state
      laws and regulations.

            The Adviser acknowledges and agrees that subject to the supervision
      and directions of the Trust's Board of Trustees, it shall be solely
      responsible for compliance with all disclosure requirements under all
      applicable federal and state laws and regulations relating to the Trust or
      a Fund, including, without limitation, the 1940 Act, and the rules and
      regulations


                                        2
<PAGE>   3

      thereunder, except that each Subadviser shall have liability in connection
      with information furnished by the Subadviser to a Fund or to the Adviser.

            (c) Consistent Standards. It is recognized that the Adviser will
      perform various investment management and administrative services for
      entities other than the Trust and the Funds; in connection with providing
      such services, the Adviser agrees to exercise the same skill and care in
      performing its services under this Agreement as the Adviser exercises in
      performing similar services with respect to the other fiduciary accounts
      for which the Adviser has investment responsibilities.

            (d) Brokerage. The Adviser is authorized, subject to the supervision
      of the Trust's Board of Trustees, to establish and maintain accounts on
      behalf of each Fund with, and place orders for the purchase and sale of
      assets not allocated to a Subadviser, with or through, such persons,
      brokers or dealers ("brokers") as Adviser may select and negotiate
      commissions to be paid on such transactions. In the selection of such
      brokers and the placing of such orders, the Adviser shall seek to obtain
      for a Fund the most favorable price and execution available, except to the
      extent it may be permitted to pay higher brokerage commissions for
      brokerage and research services, as provided below. In using its
      reasonable efforts to obtain for a Fund the most favorable price and
      execution available, the Adviser, bearing in mind the Fund's best
      interests at all times, shall consider all factors it deems relevant,
      including price, the size of the transaction, the nature of the market for
      the security, the amount of the commission, if any, the timing of the
      transaction, market prices and trends, the reputation, experience and
      financial stability of the broker involved, and the quality of service
      rendered by the broker in other transactions. Subject to such policies as
      the Trustees may determine, the Adviser shall not be deemed to have acted
      unlawfully or to have breached any duty created by this Agreement or
      otherwise solely by reason of its having caused a Fund to pay a broker
      that provides brokerage and research services (within the meaning of
      Section 28(e) of the Securities Exchange Act of 1934) to the Adviser an
      amount of commission for effecting a Fund investment transaction that is
      in excess of the amount of commission that another broker would have
      charged for effecting that transaction if, but only if, the Adviser
      determines in good faith that such commission was reasonable in relation
      to the value of the brokerage and research services provided by such
      broker or dealer, viewed in terms of either that particular transaction or
      the overall responsibilities of the Adviser with respect to the accounts
      as to which it exercises investment discretion.

            It is recognized that the services provided by such brokers may be
      useful to the Adviser in connection with the Adviser's services to other
      clients. On occasions when the Adviser deems the purchase or sale of a
      security to be in the best interests of a Fund as well as other clients of
      the Adviser, the Adviser, to the extent permitted by applicable laws and
      regulations, may, but shall be under no obligation to, aggregate the
      securities to be sold or purchased in order to obtain the most favorable
      price or lower brokerage commissions and efficient execution. In such
      event, allocation of securities so sold or purchased, as well as the
      expenses incurred in the transaction, will be made by the Adviser in the
      manner the Adviser


                                        3
<PAGE>   4

      considers to be the most equitable and consistent with its fiduciary
      obligations to each Fund and to such other clients.

            (e) Securities Transactions. The Adviser will not purchase
      securities or other instruments from or sell securities or other
      instruments to a Fund; provided, however, the Adviser may purchase
      securities or other instruments from or sell securities or other
      instruments to a Fund if such transaction is permissible under applicable
      laws and regulations, including, without limitation, the 1940 Act and the
      Advisers Act and the rules and regulations promulgated thereunder or any
      exemption therefrom.

            The Adviser agrees to observe and comply with Rule 17j-1 under the
      1940 Act and the Trust's Code of Ethics, as the same may be amended from
      time to time.

            (f) Books and Records. In accordance with the 1940 Act and the rules
      and regulations promulgated thereunder, the Adviser shall maintain
      separate books and detailed records of all matters pertaining to the Funds
      and the Trust (the "Fund's Books and Records"), including, without
      limitation, a daily ledger of such assets and liabilities relating thereto
      and brokerage and other records of all securities transactions. The
      Adviser acknowledges that the Fund's Books and Records are property of the

      Trust at any time upon request and shall be available for telecopying
      without delay to the Trust during any day that the Funds are open for
      business.

      3. Expenses. During the term of this Agreement, the Adviser will pay all
expenses incurred by it in connection with its activities under this Agreement
other than the cost of securities, commodities and other investments (including
brokerage commissions and other transaction charges, if any) purchased for a
Fund. The Adviser shall, at its sole expense, employ or associate itself with
such persons as it believes to be particularly fitted to assist it in the
execution of its duties under this Agreement. The Adviser shall be responsible
for the expenses and costs for the officers of the Trust and the Trustees of
Trust who are "interested persons" (as defined in the 1940 Act) of the Adviser.

      It is understood that the Trust will pay all of its own expenses
including, without limitation, (1) all charges and expenses of any custodian or
depository appointed by the Trust for the safekeeping of its cash, securities
and other assets, (2) all charges and expenses paid to an administrator
appointed by the Trust to provide administrative or compliance services, (3) the
charges and expenses of any transfer agents and registrars appointed by the
Trust, (4) the charges and expenses of independent certified public accountants
and of general ledger accounting and internal reporting services for the Trust,
(5) the charges and expenses of dividend and capital gain distributions, (6) the
compensation and expenses of Trustees of the Trust who are not "interested
persons" of the Adviser, (7) brokerage commissions and issue and transfer taxes
chargeable to the Trust in connection with securities transactions to which the
Trust is a party, (8) all taxes and fees payable by the Trust to Federal, State
or other governmental agencies, (9) the cost of stock certificates representing
shares of the Trust, (10) all expenses of shareholders' and Trustees' meetings

      and of preparing, printing and distributing prospectuses and reports to
      shareholders, (11) charges and expenses of legal counsel for the Trust in
      connection with legal matters relating to the Trust, including without

      4. Compensation. For the services provided and the expenses assumed with
respect to a Fund pursuant to this Agreement, the Adviser will be entitled to
the fee listed for each Fund on Exhibit A. Such fees will be computed daily and
payable monthly at an annual rate based on a Fund's average daily net assets.

      The method of determining net assets of a Fund for purposes hereof shall
be the same as the method of determining net assets for purposes of establishing
the offering and redemption price of the Shares as described in each Fund's
Prospectus. If this Agreement shall be effective for only a portion of a month,
the aforesaid fee shall be prorated for the portion of such month during which
this Agreement is in effect.

      Notwithstanding any other provision of this Agreement, the Adviser may
from time to time agree not to impose all or a portion of its fee otherwise
payable hereunder (in advance of the time such fee or portion thereof would
otherwise accrue). Any such fee reduction may be discontinued or modified by the
Adviser at any time.

                              SUBADVISORY AGREEMENT

      THIS AGREEMENT is made and entered into on this _____ day of __________,
1998, among NATIONWIDE INVESTING FOUNDATION III, an Ohio business trust (the
"Trust"), NATIONWIDE ADVISORY SERVICES, INC. (the "Adviser"), an Ohio
corporation registered under the Investment Advisers Act of 1940 (the "Advisers
Act"), and THE DREYFUS CORPORATION, a New York corporation (the "Subadviser"),
also registered under the Advisers Act.

                                   WITNESSETH:

      WHEREAS, the Trust is registered with the Securities and Exchange
Commission (the "SEC") as an open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act");

      WHEREAS, the Adviser has, pursuant to an Advisory Agreement with the Trust
dated as of ____________,1998 (the "Advisory Agreement"), been retained to act
as investment adviser for certain of the series of the Trust which are listed on
Exhibit A to this Agreement (each, a "Fund").

      WHEREAS, the Advisory Agreement permits the Adviser to delegate certain of
its duties under the Advisory Agreement to other investment advisers, subject to
the requirements of the 1940 Act; and

      WHEREAS, the Adviser desires to retain Subadviser to assist it in the
provision of a continuous investment program for that portion of the Fund's
assets which the Adviser will assign to the Subadviser (the "Subadviser
Assets"), and Subadviser is willing to render such services subject to the terms
and conditions set forth in this Agreement.

      NOW, THEREFORE, the parties do mutually agree and promise as follows:

      1. Appointment as Subadviser. The Adviser hereby retains the Subadviser to
act as investment adviser for and to manage the Subadviser Assets subject to the
supervision of the Adviser and the Board of Trustees of the Trust and subject to
the terms of this Agreement; and the Subadviser hereby accepts such employment.
In such capacity, the Subadviser shall be responsible for the investment
management of the Subadviser Assets. It is recognized that the Subadviser now
acts, and that from time to time hereafter may act, as investment adviser to one
or more other investment companies and to fiduciary or other managed accounts
and that the Adviser and the Trust have no objection to such activities.

      2. Duties of Subadviser.

            (a) Investments. The Subadviser is hereby authorized and directed
      and hereby agrees, subject to the stated investment policies and
      restrictions of the Fund as set forth in the Fund's prospectus and
      statement of additional information as currently in effect and as
      supplemented or amended from time to time (collectively referred to
      hereinafter as the "Prospectus") and subject to the directions of the
      Adviser and the Fund's Board of Trustees, to purchase, hold and sell
      investments for the Subadviser Assets and to monitor on a continuous basis
      the performance of the Subadviser Assets. In providing these services, the
      Subadviser will conduct a continual program of investment, evaluation and,
      if appropriate,


                                       1
<PAGE>   2

      sale and reinvestment of the Subadviser Assets. The Adviser agrees to
      provide the Subadviser with such assistance as may be reasonably requested
      by the Subadviser in connection with its activities under this Agreement,
      including, without limitation, information concerning the Fund, its funds
      available, or to become available, for investment and generally as to the
      conditions of the Fund's affairs.

            (b) Compliance with Applicable Laws and Governing Documents. In the
      performance of its duties and obligations under this Agreement, the
      Subadviser shall act in conformity with the Trust's Declaration of Trust
      and By-Laws and the Prospectus and with the instructions and directions
      received in writing from the Adviser or the Trustees of the Trust and will
      conform to and comply with the requirements of the 1940 Act, the Internal
      Revenue Code of 1986, as amended (the "Code"), (including the requirements
      for qualification as a regulated investment company), and all other
      applicable federal and state laws and regulations. Notwithstanding the
      foregoing, the Adviser shall remain responsible for ensuring the Fund's
      overall compliance with the 1940 Act, the Code and all other applicable
      federal and state laws and regulations and the Subadviser is only
      obligated to comply with this subsection (b) with respect to the
      Subadviser Assets.

            The Adviser will provide the Subadviser with reasonable advance
      notice of any change in the Fund's investment objectives, policies and
      restrictions as stated in the Prospectus, and the Subadviser shall, in the
      performance of its duties and obligations under this Agreement, manage the
      Subadviser Assets consistent with such changes, provided the Subadviser
      has received notice of the effectiveness of such changes from the Trust or
      the Adviser. For purposes of this subsection, receipt of a modified
      Prospectus by the Subadviser shall constitute notice of the effectiveness
      of such changes. The Adviser acknowledges and agrees that the Prospectus
      will at all times be in compliance with all disclosure requirements under
      all applicable federal and state laws and regulations relating to the
      Trust or the Fund, including, without limitation, the 1940 Act, and the
      rules and regulations thereunder, and that the Subadviser shall have no
      liability in connection therewith, except as to the accuracy of material
      information furnished by the Subadviser to the Fund or to the Adviser
      specifically for inclusion in the Prospectus. The Subadviser hereby agrees
      to provide to the Adviser in a timely manner such information relating to
      the Subadviser and its relationship to, and actions for, the Fund as may
      be required to be contained in the Prospectus.

            (c) Voting of Proxies. The Subadviser shall have the power to vote,
      either in person or by proxy, all securities in which the Subadviser
      Assets may be invested from time to time, and shall not be required to
      seek or take instructions from the Adviser or the Fund or take any action
      with respect thereto. If both the Subadviser and another entity managing
      assets of the Fund have invested in the same security, the Subadviser and
      such other entity will each have the power to vote its pro rata share of
      the security.

            (d) Agent. Subject to any other written instructions of the Adviser
      or the Trust, the Subadviser is hereby appointed the Adviser's and the
      Trust's agent and attorney-in-fact for the limited purposes of executing
      account documentation, agreements, contracts and other documents as the
      Subadviser shall be requested by brokers, dealers, counterparties and
      other persons in connection with its management of the Subadviser Assets.
      The Subadviser agrees to provide the Adviser and the Trust with copies of
      any such agreements executed on behalf of the Adviser or the Trust.


                                        2
<PAGE>   3

            (e) Brokerage. The Subadviser is authorized, subject to the
      supervision of the Adviser and the Trust's Board of Trustees, to establish
      and maintain accounts on behalf of the Fund with, and place orders for the
      purchase and sale of the Subadviser Assets with or through, such persons,
      brokers or dealers ("brokers") as Subadviser may elect and negotiate
      commissions to be paid on such transactions. The Subadviser shall place
      all orders for the purchase and sale of Subadviser Assets for the Fund's
      account with brokers selected by the Subadviser. In the selection of such
      brokers and the placing of such orders, the Subadviser shall seek to
      obtain for the Fund, in its opinion, the most favorable price and
      execution available, except to the extent it may be permitted to pay
      higher brokerage commissions for brokerage and research services, as
      provided below. In using its reasonable efforts to obtain for the Fund the
      most favorable price and execution available, the Subadviser, bearing in
      mind the Fund's best interests at all times, shall consider all factors it
      deems relevant, including price, the size of the transaction, the nature
      of the market for the security, the amount of the commission, if any, the
      timing of the transaction, market prices and trends, the reputation,
      experience and financial stability of the broker involved, and the quality
      of service rendered by the broker or dealer in other transactions. Subject
      to such policies as the Trustees may determine, or as may be mutually
      agreed to by the Adviser and the Subadviser, the Subadviser shall not be
      deemed to have acted unlawfully or to have breached any duty created by
      this Agreement or otherwise solely by reason of its having caused the Fund
      to pay a broker that provides brokerage and research services to the
      Subadviser an amount of commission for effecting a Fund investment
      transaction that is in excess of the amount of commission that another
      broker would have charged for effecting that transaction.

            It is recognized that the services provided by such brokers may be
      useful to the Subadviser in connection with the Subadviser's services to
      other clients. On occasions when the Subadviser deems the purchase or sale
      of a security to be in the best interests of the Fund as well as other
      clients of the Subadviser, the Subadviser, to the extent permitted by
      applicable laws and regulations, may, but shall be under no obligation to,
      aggregate the securities to be sold or purchased in order to obtain the
      most favorable price or lower brokerage commissions and efficient
      execution. In such event, allocation of securities so sold or purchased,
      as well as the expenses incurred in the transaction, will be made by the
      Subadviser in the manner the Subadviser considers to be the most equitable
      and consistent with its fiduciary obligations to the Fund and to such
      other clients. It is recognized that in some cases, this procedure may
      adversely affect the price paid or received by the Fund or the size of the
      position obtainable for, or disposed of by, the Fund.

            (f) Securities Transactions. The Subadviser and any affiliated
      person of the Subadviser will not purchase securities or other instruments
      from or sell securities or other instruments to the Fund; provided,
      however, the Subadviser and any affiliated person of the Subadviser may
      purchase securities or other instruments from or sell securities or other
      instruments to the Fund if such transaction is permissible under
      applicable laws and regulations, including, without limitation, the 1940
      Act and the Advisers Act and the rules and regulations promulgated
      thereunder.

            The Subadviser, including its Access Persons (as defined in
      subsection (e) of Rule 17j-1 under the 1940 Act), agrees to observe and
      comply with Rule 17j-1 and the Subadviser's Code of Ethics (which shall
      comply in all material respects with Rule 17j-1), as the same may be
      amended from time to time. On a quarterly basis, the Subadviser will
      either (i) certify to the Adviser that, to the best of its knowledge at
      that time, the Subadviser and its


                                        3

      Access Persons have complied with the Subadviser's Code of Ethics with
      respect to the Subadviser Assets or (ii) identify any material violations
      which have occurred with respect to the Subadviser Assets.

            (g) Books and Records. Pursuant to the 1940 Act and the rules and
      regulations promulgated thereunder, the Subadviser shall maintain separate
      books and detailed records of all matters pertaining to the Subadviser
      Assets (the "Fund's Books and Records"), including, without limitation, a
      daily ledger of such assets and liabilities relating thereto and brokerage
      and other records of all securities transactions. The Fund's Books and
      Records (relating to the Subadviser Assets)shall be available to the
      Adviser at any time upon request and shall be available for telecopying
      without delay to the Adviser during any day that the Fund is open for
      business.

            (h) Information Concerning Subadviser Assets and Subadviser. From
      time to time as the Adviser or the Fund may reasonably request, the
      Subadviser will furnish the requesting party reports on portfolio
      transactions and reports on Subadviser Assets held in the portfolio, all
      in such detail as the Adviser or the Fund may reasonably request. The
      Subadviser will also inform the Adviser in a timely manner of material
      changes in primary portfolio manager(s) responsible for Subadviser Assets
      or of material changes in the control of the Subadviser. The Subadviser
      will make available one or more of its officers and employees to meet with
      the Trust's Board of Trustees on reasonable due notice to review the
      Subadviser Assets.

            The Subadviser will also provide such information or perform such
      additional acts as are customarily performed by a subadviser and may be
      required for the Fund or the Adviser to comply with their respective
      obligations under applicable laws, including, without limitation, the
      Code, the 1940 Act, the Advisers Act, the Securities Act of 1933, as
      amended (the "Securities Act") and any state securities laws, and any rule
      or regulation thereunder.

            (i) Custody Arrangements. The Subadviser shall on each business day
      provide the Adviser and the Trust's custodian such information as the
      Adviser and the Trust's custodian may reasonably request relating to all
      transactions concerning the Subadviser Assets.

            (j) Historical Performance Information. To the extent agreed upon by
      the parties, the Subadviser will provide the Trust with historical
      performance information on similarly managed investment companies or for
      other accounts to be included in the Prospectus, or for any other uses
      permitted by applicable law.

      3. Independent Contractor. In the performance of its duties hereunder, the
Subadviser is and shall be an independent contractor and unless otherwise
expressly provided herein or otherwise authorized in writing, shall have no
authority to act for or represent the Fund, the Trust or the Adviser in any way
or otherwise be deemed an agent of the Fund, the Trust or the Adviser.

      4. Expenses. During the term of this Agreement, Subadviser will pay all
expenses incurred by it in connection with its activities under this Agreement
other than the cost of securities, commodities and other investments (including
brokerage commissions and other transaction charges, if any) purchased for the
Fund. The Subadviser shall, at its sole expense, employ or associate itself with
such persons as it believes to be particularly fitted to assist it in the
execution of its duties under this Agreement. The Subadviser shall not be
responsible for the Trust's, the Fund's or Adviser's expenses. The Trust or the
Adviser, as the case may be, shall reimburse the Subadviser for any


                                        4
<PAGE>   5

expenses of the Fund or the Adviser as may be reasonably incurred by such
Subadviser on behalf of the Fund or the Adviser. The Subadviser shall keep and
supply to the Trust and the Adviser reasonable records of all such expenses.

      5. Compensation. For the services provided and the expenses assumed with
respect to the Fund pursuant to this Agreement, the Subadviser will be entitled
to the fee listed for each Fund on Exhibit A. Such fees will be computed daily
and payable no later than the seventh (7th) business day following the end of
each month, from the Adviser or the Trust, calculated at an annual rate based on
the Subadviser Assets' average daily net assets.

      The method of determining net assets of the Fund for purposes hereof shall
be the same as the method of determining net assets for purposes of establishing
the offering and redemption price of the Shares as described in the Fund's
Prospectus. If this Agreement shall be effective for only a portion of a month,
the aforesaid fee shall be prorated for the portion of such month during which
this Agreement is in effect.

      Notwithstanding any other provision of this Agreement, the Subadviser may
from time to time agree not to impose all or a portion of its fee otherwise
payable hereunder (in advance of the time such fee or portion thereof would
otherwise accrue). Any such fee reduction may be discontinued or modified by the
Subadviser at any time.

                                       AND
                       NATIONWIDE ADVISORY SERVICES, INC.

      AGREEMENT, made as of this _____ day of _________________, 1998, by and
between Nationwide Investing Foundation III, an Ohio business trust (the
"Trust"), and Nationwide Advisory Services, Inc., an Ohio corporation (the
"Underwriter").

                              W I T N E S S E T H:

      WHEREAS, the Trust is engaged in business as an open-end management
investment company, as defined in the Investment Company Act of 1940 (the "1940
Act"), and is so registered with the Securities and Exchange Commission (the
"SEC") under the provisions of that Act; and

      WHEREAS, it is mutually desired that the Underwriter undertake as agent of
the Trust, the sale and distribution of Shares of each of the investment
portfolios of the Trust which are listed on Schedule A to this Agreement (each a
"Fund");

      NOW, THEREFORE, the parties do mutually agree and promise as follows:

      1. Appointment as Underwriter. The Trust hereby appoints the Underwriter
their agent for the sale of the Shares covered by the registration statement for
the Trust. As used in this Agreement, the "registration statement" shall refer
to the Trust's current registration on Form N-1A and shall include the
prospectus (Part A), Statement of Additional Information (Part B) and Part C,
and together the current prospectus and Statement of Additional Information
shall be referred to as the "Prospectus." The Trust understands that Underwriter
is now and may in the future be the distributor of the shares of several
investment companies or series (together, "Companies") including Companies
having investment objectives similar to those of the Trust. The Trust agrees
that Distributor's duties to such Companies shall not be deemed in conflict with
its duties to the Trust under this paragraph.

      2. Duties of Underwriter. (a) The Underwriter hereby accepts such
appointment as distributor for the sale of the Shares and agrees that it will
use its best efforts to solicit orders for the sale of the Shares and will
undertake such advertising and promotion as it believes reasonable in connection
with such solicitation. The Underwriter shall, at its own expense, finance
appropriate activities which are primarily intended to result in the sale of the
Shares, including, but not limited to, advertising, compensation of
underwriters, dealers and sales personnel, the printing and mailing of
prospectuses to other than current Shareholders, and the printing and mailing of
sales literature.

            (b) In its capacity as Underwriter, Underwriter agrees to act in
conformity with the Prospectus and the Trust's Declaration of Trust and Bylaws
and with instructions received from the Trustees of the Trust and shall conform
to and comply with all applicable laws, rules and regulations, including,
without limitation, the 1940 Act, all rules and regulations promulgated by the


                                        1
<PAGE>   2

SEC thereunder and all rules and regulations adopted by any securities
association registered under the Securities Exchange Act of 1934.

            (c) The Underwriter may, and when requested by the Trustees or their
representatives shall, suspend its efforts to effectuate sales of Shares on
behalf of the Trust at any time when in the opinion of the Underwriter or of the
Trustees no sales should be made because of market or other economic
considerations or abnormal circumstances of any kind. The Trust and its Trustees
may withdraw the offering of the Shares (i) at any time with the consent of the
Underwriter, or (ii) without such consent when so required by the provisions of
any statute or of any order, rule or regulation of any governmental body having
jurisdiction. It is mutually understood and agreed that the Underwriter does not
undertake to sell all or any specific portion of the Shares.

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

      3. Sale and Payment of Shares. (a) The Underwriter shall have the right to
purchase Shares of the Funds at the net asset value in effect at the time that
orders for such Shares are received by the Trust or its authorized agent and to
sell such Shares at the applicable public offering price through dealers or
other persons. The public offering price for the Shares of each Fund shall equal
to the sum of (a) the net asset value per Share next computed for a Fund by the
Trust and (b) any applicable sales charge, all as set forth in the current
Prospectus for the Fund. The net asset value of the Shares shall be determined
in accordance with the provisions of the Trust's Declaration of Trust and the
Prospectus. The Trust shall allow the Underwriter as compensation for its
services the particular sales charge applicable to the Shares sold. The
Underwriter may fix the portion of the distribution charge to be allowed to
dealers and others.

            (b) The Underwriter agrees that it will deliver or cause to be
delivered to the Trust or to its authorized agent, as the Trustees may direct,
an amount equal to the net asset value of Shares for which purchase orders have
been placed with and accepted by the Underwriter and shall forward to the Trust
or its authorized agent, as the Trustees may direct, all orders for the purchase
of Shares with reasonable promptness after the receipt and acceptance thereof by
the Underwriter; provided, however, that the Underwriter shall have the sole
right to accept or reject all orders for the purchase of Shares and will return
promptly any rejected order together with the consideration which accompanied
it.

      4. Issuance of Shares. The Trust reserves the right to issue, transfer or
sell Shares, which are otherwise subject to a sales charge, at net asset value
(a) in connection with the merger or consolidation of the Trust or the Fund(s)
with any other investment company or the acquisition by the Trust or the Fund(s)
of all or substantially all of the assets or of the outstanding Shares of any
other investment company; (b) in connection with a pro rata distribution
directly to the holders of


                                        2
<PAGE>   3

Shares in the nature of a stock dividend or split; (c) upon the exercise of
subscription rights granted to the holders of Shares on a pro rata basis; (d) in
connection with the issuance of Shares pursuant to any exchange and reinvestment
privileges described in the Prospectus of a Fund; (e) in a sale to the Trustees,
employees, officers and directors of or salespersons employed by the Underwriter
and to officers, directors and employees of any investment adviser of the Trust;
and (f) otherwise in accordance with the Prospectus of a Fund.

      5.    The Trust agrees as follows:

            (1)   to use its best efforts to maintain its registration as a
                  diversified open-end management investment company under the
                  1940 Act, and to comply with all of the provisions of that Act
                  and of the rules and regulations thereunder;

            (2)   to register its Shares under the Securities Act of 1933, and
                  to use its best efforts to maintain such registration;

            (3)   to prepare and file such amendments to the registration
                  statements and Prospectus and other statements or reports as
                  may be necessary to comply with the Securities Act of 1933,
                  the 1940 Act, and the rules and regulations of the SEC;

            (4)   to furnish the Underwriter with a sufficient number of
                  Prospectuses to meet the Underwriter's requirements for use in
                  connection with sales of Shares, and that the Underwriter will
                  not be required to use any prospectuses of the Trust which
                  shall not be in form and content satisfactory to counsel for
                  the Underwriter; and

            (5)   at the request of the Underwriter, to take such steps as may
                  be necessary and feasible to qualify Shares for sale in each
                  state, territory or dependency of the United States of
                  America, in the District of Columbia and in foreign countries,
                  in accordance with the laws thereof, and to renew or extend
                  any such qualification; provided, however, that the Trust
                  shall not be required to qualify Shares or to maintain the
                  qualification of Shares in any state, territory, dependency,
                  district or country where they shall deem such qualification
                  disadvantageous to the Trust.

      6.    The Underwriter agrees as follows:

            (1)   that the Underwriter and its officers or directors will
                  purchase and keep Shares only for investment purposes;

            (2)   that it will not purchase Shares from the Shareholders except
                  as agent for the Trust;

            (3)   that upon the request of the Trust or its representative it
                  will furnish to the Trust or such representative any
                  information in its possession which is pertinent to the
                  preparation of any registration statement, prospectus or
                  amendment thereto, or any report required by law or
                  regulation; and

            (4)   that neither the Underwriter nor any other person authorized
                  by it to solicit purchases of Shares shall give any
                  information or make any representations, other than those
                  contained in the Registration Statement or Prospectus or in


                                        3
<PAGE>   4

                  any supplemental sales literature authorized by the Trust for
                  use in connection with the sale of shares.

      7. Fees and Expenses. The Trust may pay a distribution fee to the
Underwriter determined in accordance with any applicable Distribution Plan
adopted by the Trustees and approved by the shareholders pursuant to Rule 12b-1
under the 1940 Act.

      The Underwriter shall pay expenses for (i) printing and distributing any
prospectus and preparing, printing and distributing any other literature used by
the Underwriter in connection with the offering of the Shares for sale to the
public (except such expenses as may be incurred by the Trust in connection with
the preparation, printing and distribution of any Prospectus, report or other
communication to Shareholders, to the extent that such expenses are necessarily
incurred to effect compliance by the Trust with any Federal or state law or to
enable such distribution to Shareholders), and (ii) expenses of advertising in
connection with such offering. The Trust will pay or cause to be paid (i) all
fees and expenses for the issue and delivery of Shares, and (ii) all auditing
expenses of the Trust.

      8. Repurchase of Shares. The Trustees hereby appoints the Underwriter its
agent to repurchase Shares, upon the written request of the Shareholders,
accompanied by the certificate or certificates representing such Shares (if
certificates for such Shares have been issued by the Trust) properly endorsed
for transfer, at the net asset value in effect at the time when the sale is
made.

      9. Indemnification. (a) The Trust agrees to indemnify, defend and hold the
Underwriter, its directors, officers and employees, and any person who controls
the Underwriter within the meaning of Section 15 of the Securities Act
("Underwriter Affiliates") free and harmless from and against any and all
claims, demands, liabilities and expenses (including the cost of investigating
or defending such claims, demands or liabilities and any counsel fees incurred
in connection therewith) which the Underwriter and the Underwriter Affiliates
may incur under the Securities Act or under common law or otherwise, arising out
of or based upon any untrue statement, or alleged untrue statement, of a
material fact contained in any registration statement or any prospectus or
arising out of or based upon any omission, or alleged omission, to state a
material fact required to be stated in either any registration statement or any
prospectus or necessary to make the statements in either thereof not misleading.
Provided, however, that the Trust's agreement to indemnify the Underwriter and
the Underwriter Affiliates shall not be deemed to cover any claims, demands,
liabilities or expenses arising out of any information or representations which
were furnished in writing to the Trust by the Underwriter, or arising out of or
based upon any omission or alleged omission to state a material fact in
connection with the giving of such information required to be stated in such
answers or necessary to make the answers not misleading; and further provided
that the Trust's agreement to indemnify Underwriter and the Underwriter
Affiliates shall not be deemed to cover any liability to the Trust or its
Shareholders to which the Underwriter would otherwise be subject by reason of
willful misfeasance, bad faith or gross negligence in the performance of its
duties, or by reason of the Underwriters reckless disregard of its obligations
and duties under this Agreement.

            (b) The Underwriter agrees to indemnify, defend and hold the Trust,
its several officers and Trustees and any person who controls the Trust within
the meaning of Section 15 of the Securities Act ("Trust Affiliates") free and
harmless from and against any and all claims, demands,


                                        4
<PAGE>   5

liabilities and expenses (including the costs of investigating or defending such
claims, demands or liabilities and any counsel fees incurred in connection
therewith) which the Trust and the Trust Affiliates may incur under the
Securities Act or under common law or otherwise, but only to the extent that
such liability or expense incurred by the Trust or the Trust Affiliates
resulting from such claims or demands, shall arise out of or be based upon any
untrue, or alleged untrue, statement of a material fact contained in information
furnished in writing by the Underwriter to the Trust and used in the answers to
any of the items of the registration statement or in the Prospectus, or shall
arise out of or be based upon any omission, or alleged omission, to state a
material fact in connection with such information furnished in writing by the
Underwriter to the Trust required to be stated in such answers or necessary to
make such information not misleading.

      10. Term, Duration and Termination. The term of this Agreement shall begin

on that date, the date an amendment to Schedule A to this Agreement adding the
new Fund is executed) and, unless sooner terminated as provided herein, shall
remain in effect for a period of two (2) years from that date. Thereafter, if
not terminated, this Agreement shall continue in effect from year to year
thereafter provided such continuance shall be approved at least annually by (a)
a majority of the Trustees or by the affirmative vote or written approval of the
holders of a majority of the outstanding Shares and (b) a majority of the
Trustees who are not interested persons of the Underwriter, the term "interested
person" having the meaning defined in Section 2(a)(19) of the 1940 Act. This
Agreement is terminable without penalty, on not less than sixty days prior
written notice, by the Trust's Board of Trustees, by vote of a majority of the
outstanding voting securities of the Trust or by the Underwriter. This Agreement
will also terminate automatically in the event of its assignment (as such term
is defined in the 1940 Act).

      11. Amendment. This Agreement may not be amended or changed in any manner
except by a written agreement executed by both the Trust and the Underwriter.

      12. Jurisdiction. This Agreement shall be governed by and in accordance
with the substantive laws of the State of Ohio without reference to choice of
law principles thereof and in accordance with the 1940 Act. In case of any
conflict, the 1940 Act shall control.

      13. Limitation of Liability of the Trustees and Shareholders. It is
understood and is expressly stipulated that this Agreement is executed on behalf
of the Trustees of Nationwide Investing Foundation III as Trustees and not
individually and that the obligations of this Agreement are not binding upon any
of the Trustees or shareholders of the Trust individually but are binding only
upon the assets and property of the Trust.

            the account of the Fund. If Securities sold by the Fund are held in
            a Book-Entry System or Securities Depository, the Custodian shall
            transfer such Securities upon (i) receipt of advice from the
            Book-Entry System or Securities depository that payment for such

      4.2 Liability for Payment in Advance of Receipt of Securities Purchased.
In any and every case where payment for the purchase of Securities for a Fund is
made by the Custodian in advance of receipt for the account of the Fund of the

form as shall be satisfactory to it, and may deliver Securities and arrange for
payment in accordance with the customs prevailing among dealers in Securities.

other provision of this Agreement, the Custodian, when instructed to deliver

final payment therefor. In any such case, the Trust shall bear the risk that
final payment for such Securities may not be made or that such Securities may be
returned or otherwise held or disposed of by or through the person to whom they
were delivered, and the Custodian shall have no liability for any of the
foregoing.

      4.5 Payment for Securities Sold, etc. In its sole discretion and from time
to time, the Custodian may credit the relevant Custody Account, prior to actual
receipt of final payment thereof, with (i) proceeds from the sale of Securities
which it has been instructed to deliver against payment, (ii) proceeds from the
redemption of Securities or other assets of the Trust, and (iii) income from
cash, Securities or other assets of the Trust. Any such credit shall be

any action with respect to Securities, which may, in the opinion of the
custodian, result in the Custodian or its nominee becoming liable for the
payment of money or incurring liability of some other form, the Custodian shall
not be required to take such action until the Trust shall have provided
indemnity therefor to the Custodian in an amount and form satisfactory to the
Custodian.

                                  FORCE MAJEURE

      Neither the Custodian nor the Trust shall be liable for any failure or
delay in 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 disturbances; sabotage; strikes; epidemics; riots; power

date first set forth above and shall continue in full force and effect until
terminated as hereinafter provided.

      10.2 Termination. Either party hereto may terminate this Agreement by
giving to the other party a notice in writing specifying the date of such
termination, which shall be not less than ninety (90) days after the date of the
giving of such notice. If a successor custodian shall have been appointed by the
Board of Trustees, the Custodian shall, upon receipt of a notice of acceptance
by the successor custodian, on such specified date of termination (a) deliver
directly to the successor custodian all Securities (other than Securities held
in a Book-Entry System or Securities Depository) and cash then owned by the
Trust and held by the Custodian as custodian, and (b) transfer any Securities
held in a Book-Entry System or Securities Depository to an account of or for the
benefit of the Trust at the successor custodian, provided that the Trust shall
have paid to the Custodian all fees, expenses and other amounts to the payment
or reimbursement of which it shall then be entitled. Upon such delivery and
transfer, the Custodian shall be relieved of all obligations under this
Agreement. The Trust may at any time immediately terminate this Agreement in the
event of the appointment of a conservator or receiver for the Custodian by
regulatory authorities in the State of Ohio or upon the happening of a like
event at the direction of an appropriate regulatory agency or court of competent
jurisdiction.

      10.3 Failure to Appoint Successor Custodian. If a successor custodian is
not designated by the Trust on or before the date of termination specified
pursuant to Section 10.1 above, then the Custodian shall have the right to
deliver to a bank or trust company of its own selection, which is (a) a "Bank"
as defined in the 1940 Act, (b) has aggregate capital, surplus and undivided
profits as shown on its then most recent published report of not less than $25
million, and (c) is doing business in New York, New York, all Securities, cash
and other property held by Custodian under this Agreement and to transfer to an
account of or for the Trust at such bank or trust company all Securities of the
Trust held in a Book-Entry System or Securities Depository. Upon such delivery
and transfer, such bank or trust company shall be the successor custodian under
this Agreement and the Custodian shall be relieved of all obligations under this
Agreement. If, after reasonable inquiry, Custodian cannot find a successor
custodian as contemplated in this Section 10.3, then Custodian shall have the
right to deliver to the Trust all Securities and cash then owned by the Trust
and to transfer any Securities held in a Book-Entry System or Securities
Depository to an account of or for the Trust. Thereafter, the Trust shall be
deemed to be its own custodian with respect to the Trust and the Custodian shall
be relieved of all obligations under this Agreement.

      The foregoing, along with any additional services that the Administrator
      shall agree in writing to perform for the Trust hereunder, shall hereafter
      be referred to as "Administrative Services." In compliance with the

      Administrator hereby agrees that all records that it maintains for the
      Trust are the property
<PAGE>   4

      of the Trust and further agrees to surrender promptly to the Trust any of
      such records upon the Trust's request. The Administrator further agrees to
      preserve for the periods prescribed by Investment Company Act Rule 31a-2
      the records required to be maintained by Investment Company Act Rule
      31a-1. Administrative Services shall not include any duties, functions, or
      services to be performed for the Trust by the Trust's investment adviser,
      custodian, or transfer agent pursuant to their agreements with the Trust.

      The Administrator acknowledges the importance of efficient and prompt
      transmission of information to the life insurance companies affiliated
      with the Administrator ("Nationwide"), the purchaser of Trust shares to
      fund the obligations of certain variable annuity contracts. The
      Administrator agrees to use its best efforts to meet the deadline for
      transmission of pricing information presently set by Nationwide and such
      other time deadlines as may be established from time to time in the
      future.

      When performing Administrative Services to the Trust and for the Funds,
      the Administrator will comply with the provisions of the Declaration of
      Trust and Bylaws of the Trust, will safeguard and promote the welfare of
      the Trust and the Funds, and will comply with the policies that the
      Trustees may from time to time reasonably determine, provided that such
      policies are not in conflict with this Agreement, the Trust's governing
      documents, or any applicable statutes or regulations.

3.    Expenses. The Administrator shall be responsible for expenses incurred in
      providing all the Administrative Services to the Trust, including the
      compensation of the Administrator's employees who serve as officers of the
      Trust, except that the Trust shall reimburse the Administrator for the
      cost of the pricing services that the Administer utilizes. The Trust (or
      the Trust's investment adviser) shall be responsible for all other
      expenses of the Trust, including without limitation: (i) investment
      advisory and subadvisory fees; (ii) interest and taxes; (iii) brokerage
      commissions and other costs in connection with the purchase or sale of
      securities and other investment instruments; (iv) fees and expenses of the
      Trust's trustees, other than those who are "interested persons" of the
      Administrator or investment adviser of the Trust; (v) legal and audit
      expenses; (vi) custodian and transfer and dividend disbursing agent fees
      and expenses; (vii) fees and expenses related to the registration and
      qualification of the Trust and the Trust's shares for distribution under
      state and federal securities laws; (viii) expenses of printing and mailing
      reports and notices and proxy material to beneficial shareholders of the
      Trust; (ix) all other expenses incidental to holding meetings of the
      Trust's shareholders, including proxy solicitations therefor; (x)
      insurance premiums for fidelity and other coverage; (xi) association
      membership dues; (xii) such nonrecurring or extraordinary expenses as may
      arise, including those relating to actions, suits or proceedings to which
      the Trust is a party and the legal obligation which the Trust may have to
      indemnify the Trust's trustees and officers with respect thereto.

4.    Compensation. For the Administrative Services provided, the Trust hereby
      agrees to pay and the Administrator hereby agrees to accept as full
      compensation for its services rendered
<PAGE>   5

      hereunder the administrative fee listed for each Fund on Exhibit A. Such
      fees will be computed daily and payable monthly at an annual rate based on
      a Fund's average daily net assets and will be paid monthly as soon as
      practicable after the last day of each month.

      In case of termination of this Agreement during any month, the
      administrative fee for that month shall be reduced proportionately on the
      basis of the number of business days during which it is in effect, and the
      fee computed upon the average net assets for the business days it is so in
      effect for that month.

5.    Responsibility of Administrator.

      a.    The Administrator shall not be liable for any error of judgment or
            mistake of law or for any loss suffered by the Trust in connection
            with the matters to which this Agreement relates, except a loss
            resulting from willful misfeasance, bad faith or negligence on its
            part in the performance of its duties or from reckless disregard by
            it of its obligations and duties under this Agreement. Any person,
            even though also an officer, director, partner, employee or agent of
            the Administrator, who may be or become an officer or trustee of the
            Trust, shall be deemed, when rendering services to the Trust or
            acting on any business of the Trust (other than services or business
            in connection with the duties of the Administrator hereunder) in
            accordance with his responsibilities to the Trust as such officer or
            trustee, to be rendering such services to or acting solely for the
            Trust and not as an officer, director, partner, employee or agent or
            one under the control or direction of the Administrator even through
            paid by the Administrator.

      b.    The Administrator shall be kept indemnified by the Trust and be
            without liability for any action taken or thing done by it in
            performing the Administrative Services in accordance with the above
            standards; provided, however, that the Trust will not indemnify the
            Administrator for the portion of any loss or claim caused, directly
            or indirectly, by the negligence, wilfull misfeasance or bad faith
            of the Administrator or by the Administrator's reckless disregard of
            its duties and obligations hereunder. In order that the
            indemnification provisions contained in this Section 5 shall apply,
            however, it is understood that if in any case the Trust may be asked
            to indemnify or save the Administrator harmless, the Trust shall be
            fully and promptly advised of all pertinent facts concerning the
            situation in question, and it is further understood that the
            Administrator will use all reasonable care to identify and notify
            the Trust promptly concerning any situation which presents or
            appears likely to present the probability of such a claim for
            indemnification against the Trust. The Trust shall have the option
            to defend the Administrator against any claim which may be the
            subject of this indemnification. In the event that the Trust so
            elects it will so notify the Administrator and thereupon the Trust
            shall take over complete defense of the claim, and the Administrator
            shall in such situation initiate no further legal or other expenses
            for which it shall seek indemnification under this Section. The
            Administrator shall in
<PAGE>   6

            no case confess any claim or make any compromise or settlement in
            any case in which the Trust will be asked to indemnify the
            Administrator except with the Trust's written consent.

6.    Duration and Termination.

      a.    This Agreement shall become effective as of the date first written
            above. The Agreement may be terminated at any time, without payment
            of any penalty, by either party upon 90 days' advance written notice
            to the other party. The Agreement may also be terminated immediately
            upon written notice to the other party in the event of a material
            breach of any provision of this Agreement by such other party.

      b.    Upon the termination of this Agreement, the Trust shall pay to the
            Administrator such compensation as may be payable prior to the
            effective date of such termination. In the event that the Trust
            designates a successor to any of the Administrator's obligations
            hereunder, the Administrator shall, at the direction of the Trust,
            transfer to such successor all relevant books, records and other
            data established or maintained by the Administrator under the
            foregoing provisions.

      discharged or terminated orally, but only by an instrument in writing
      signed by the party against which an enforcement of the change, waiver,
      discharge or termination is sought.
