                                    THE FUND


The Fund is an open-end diversified management investment company which
currently consists of 20 separate portfolios - the Equity Portfolio, the Money
Market Portfolio, the Bond Portfolio, the Omni Portfolio, the International
Portfolio, the Capital Appreciation Portfolio, the Small Cap Portfolio, the
International Small Company Portfolio, the Aggressive Growth Portfolio, the Core
Growth Portfolio, the Growth & Income Portfolio, the S&P 500 Index Portfolio,
the Social Awareness Portfolio, the Strategic Income Portfolio, the Firstar

other purposes, but unless there is a change in applicable law, they will not be
sold directly to the public.

The Fund is a Maryland corporation. It was created on November 2, 1982 when O.N.
Fund, Inc. was merged into O.N. Market Yield Fund, Inc. The shares of O.N. Fund,
Inc. were converted to an equal number of shares of the Equity Portfolio, all
shares of O.N. Market Yield Fund, Inc. were converted into an equal number of
shares of the Money Market Portfolio, and a Bond Portfolio was created. The Omni
Portfolio was added in 1984, the International Portfolio in 1993, the Capital
Appreciation and Small Cap Portfolios in 1994, the International Small Company
and Aggressive Growth Portfolios in 1995, the Core Growth, Growth & Income, S&P
500 Index, Social Awareness, Strategic Income, Firstar Growth & Income and

Interests in each portfolio are represented by a separate class of the Fund's
capital stock, par value $1. Each class represents an undivided interest in the
assets of the portfolio corresponding to that class. All shares of each
portfolio have one vote per share and are freely transferable. When matters
arise that affect only one portfolio, shares of just that portfolio are entitled
to vote on those matters. Approval of certain matters by a vote of all Fund
shareholders may not bind a portfolio whose shareholders did not approve that
matter.

                                       3

Each share of each portfolio may participate equally in the portfolio's
dividends, distributions and net assets. The shares of each portfolio, when
issued, will be fully paid and non-assessable, have no preemptive, conversion,
cumulative dividend or similar rights, and are freely transferable. Fund shares
do not have cumulative voting rights. This means the holders of more than half
of the Fund shares voting to elect directors can elect all the directors if they
so choose. In that event, the holders of the remaining shares could not elect
any directors.

All of the outstanding Fund shares are owned of record by ONLI and ONLAC and are
held in their various separate accounts. The shares held in connection with
those separate accounts are voted by ONLI or ONLAC in accordance with
instructions received from the owners of variable contracts issued in connection
with such separate accounts and persons receiving payments under the variable
contracts. Fund shares attributable to contracts owned by ONLI and ONLAC, and
Fund shares not attributable to variable contracts, will be voted in proportion
to instructions received from all variable contract owners.

American Data Services, Inc. is the Fund's transfer agent and fund accounting
agent. It is located at 150 Motor Parkway, Suite 109, Hauppauge, New York 11788.
Firstar is custodian for those portfolios other than the International and
International Small Company portfolios. The custodian for the International and
International Small Company portfolios is Investors Fiduciary Trust Company. It
is located at 801 Pennsylvania Street, Kansas City, Missouri. For assets held
outside the United States, the custodians enter into subcustodial agreements.
The Board of Directors approves all these relationships.


                                FUND PERFORMANCE

From time to time, we advertise the current yield, average annual total return
and cumulative total returns for the portfolios. We might compare the results to
other similar mutual funds or unmanaged indices. Management's discussion and
analysis of the Fund's performance is included in the Fund's most-recent annual
report and is available free upon request.

Total return for a portfolio reflects the sum of all of its earnings plus any
changes in the value of its assets, reduced by all expenses accrued during a
measurement period. For this purpose, it is assumed that all dividends and
capital gains distributions are reinvested. The average annual total return is
expressed as a percentage of an amount invested for a one-year period. Each
portfolio's average return is computed by a formula in which a hypothetical
initial investment of $1,000 is equated to an ending redeemable value from the
inception of the portfolio for one-, five- and ten-year periods. Cumulative
total return reflects a portfolio's aggregate performance, expressed as a dollar
amount change, from the beginning to the end of the period.

Percentage changes in net asset value per share and total returns quoted for a
portfolio include the effect of deducting that portfolio's expenses, but do not
include charges and expenses attributable to any particular insurance product.
The amount by which variable annuity separate account charges and expenses would
reduce the Fund's total return may be demonstrated by comparing the Fund's total
return to that of the variable annuity separate account for the same period.
Variable life insurance separate account charges vary significantly, depending
upon a variety of demographic factors (such as age, sex and health status) and
several contract-specific factors (such as stated amount of death benefit), but
in all cases would have the result of lowering the total return from the Fund.

From time to time the annualized yield and "effective" yield will be quoted for
the Money Market Portfolio. The Money Market Portfolio's yield refers to the
income generated by an investment in the Portfolio over the seven-day period
indicated. This income is then "annualized" by assuming that the same amount of
income generated by the Portfolio that week is generated over a 52-week period
and is shown as a percentage of the investment. "Effective" yield is calculated
similarly but, when annualized, the income earned by an investment in the
Portfolio is assumed to be reinvested. The effective yield will be slightly
higher than the yield because of the compounding effect of this assumed
reinvestment.

All performance quotations are based on historical investment performance and
are not intended to indicate future performance.

The Fund may distribute sales literature comparing the performance of its
portfolios against the Consumer Price Index or such established market indices
as the Dow Jones Industrial Average, the Standard & Poor's 500, 400, 600 or 1500
Indices, one or more of Lehman Brothers Bond Indices, the Morgan Stanley Capital
International Europe, Australia and Far East Index, the Morgan Stanley Capital
International World Index, the Russell 2000, 2500 or 3000 Indices, the New York
Stock Exchange Composite Index, the American Stock Exchange Index, the National
Association of Securities Dealers Automated Quotations Composite Index, the
Value Line Composite Index, the Investors Business Daily 6000 Index, the
Wilshire 5000 Index, IBC's Money Fund Reports, or other management investment
companies having investment objectives similar to the portfolio being compared.
These comparisons may include graphs, charts, tables or examples. The average
annual total return and cumulative total returns for each portfolio may also be
advertised.

The Fund may also advertise the performance ratings or rankings assigned to
certain portfolios or their subadvisers by various statistical services,
including Morningstar, Inc. and Lipper Analytical Services, Inc., or as they
appear in various publications including The Wall Street Journal, Investors
Business Daily, The New York Times, Barron's, Forbes, Fortune, Business Week,
Financial Services Week, Financial World, Kiplinger's Personal Finance and Money
Magazine.

The prospectus sets forth in tabular form, under the caption "Financial
Highlights," certain information concerning the Fund and its individual
portfolios. The following discussion describes the methods of calculating the
current yield of the Money Market Portfolio and the total return of all
portfolios, and states the Fund's policy with respect to each portfolio's
turnover rate.


CURRENT YIELD OF MONEY MARKET PORTFOLIO

Current annualized yield quotations for the Money Market Portfolio are based on
the portfolio's net investment income for a seven-day period and exclude any
realized or unrealized gains or losses on portfolio securities. Current
annualized yield is computed by determining the net change (exclusive of
realized gains and losses from the sale of securities and unrealized
appreciation and depreciation) in the value of a hypothetical account having a
balance of one share at the beginning of such seven-day period, dividing such
net change in account value by the value of the account at the beginning of the
period, and annualizing this quotient on a 365-day basis. The net change in
account value reflects the value of any additional shares purchased with
dividends from the original share in the account during the seven-day period,
any dividends declared on such original share and any such additional shares
during the period, and expenses accrued during the period. The Fund may also
disclose the effective yield of the Money Market Portfolio for a seven-day
period for which the current annualized yield is computed by expressing the
unannualized return on a compounded, annualized basis.


TOTAL RETURN

Total returns quoted in advertising reflect all aspects of a portfolio's
investment return, including the effects of reinvesting dividends and capital
gain distributions as well as changes in the portfolio's net asset value per
share over the period shown. Average annual returns are calculated by
determining the growth or decline in value of a hypothetical historical
investment in a portfolio over a stated period, and then calculating the
annually compounded percentage rate that would have produced the same result had
the rate of growth or decline been constant over that period. While average
annual returns are a convenient means of comparing investment alternatives, no
portfolio will experience a constant rate of growth or decline over time.

The average annual compounded rate of return for a portfolio over a given period
is found by equating the initial amount invested to the ending redeemable value
using the following formula:



                                       5
<PAGE>   6
                                 P(1 + T)n = ERV

      where:             P = a hypothetical initial payment of $1,000,
                         T = the average annual total return,
                         n = the number of years, and
                        ERV= the ending redeemable value of a hypothetical
                             $1,000 beginning-of-period payment at the end
                             of the period (or fractional portion thereof).

The average annual total returns for each of the portfolios from the inception
of the portfolio and for the one-, five- and ten-year periods ending on December
31, 1998, are as stated below:

total returns that simply reflect the change in value of an investment in a
portfolio over a period. This may be expressed as either a percentage change,
from the beginning to the end of the period, or the end-of-period dollar value
of an initial hypothetical investment. The cumulative total returns for each of

*Prior to January 1, 1999, the sub-adviser of the International and
International Small Company Portfolios was Societe Generale Asset Management
Corp. and the investment policies of the International Small Company Portfolio
were substantially different. Prior to May 1, 1999, the Firstar Growth & Income
Portfolio's investment policies were substantially different and its sub-adviser
was Firstar Bank, N.A.


PORTFOLIO TURNOVER

Each portfolio has a different expected rate of portfolio turnover. However, the
rate of portfolio turnover will not be a limiting factor when the management of
the Fund deems it appropriate to purchase or sell securities for a portfolio.
The Small Cap, Aggressive Growth and Strategic Income Portfolios may engage in
the purchase and sale of securities close to the ex-dividend date in order to
receive the anticipated dividend and then sell the securities after the
ex-dividend date. This practice could substantially increase the Portfolio's
turnover rate. Higher turnover rates are often reflected in higher portfolio
brokerage expenses. The Fund's policy with respect to each portfolio is as
follows:

      Equity Portfolio - Although this Portfolio will not normally purchase
      securities with the intention of obtaining short-term capital
      appreciation, purchases and sales will be made whenever deemed prudent and
      consistent with the investment objectives of the Portfolio. During periods
      of relatively stable market and economic conditions, it is anticipated
      that the annual portfolio turnover rate of the Portfolio will be moderate.
      During periods when changing market or economic conditions are foreseen,
      shifts in portfolio emphasis may cause the rate of portfolio turnover to
      increase. During 1998, the turnover rate for this portfolio was 25%.

      Money Market Portfolio - Since the assets of this Portfolio consist of
      short-term instruments, replacement of portfolio securities will occur
      frequently. However, since purchases are generally effected with dealers
      or issuers on a net basis, it is not expected that the Portfolio will
      incur significant brokerage commissions.

      Bond Portfolio - This Portfolio will engage in transactions when the
      Adviser believes that they will help to achieve the overall objectives of
      the Portfolio. Portfolio securities may or may not be held to maturity.
      The rate of portfolio turnover will vary from time to time but is not
      expected to exceed 50% annually. The turnover rate for this portfolio was
      12% in 1998.

      Omni Portfolio - The rate of portfolio turnover will vary from time to
      time but is not expected to exceed 50% annually. The turnover rate for
      this portfolio was 18% in 1998.

      International Portfolio - Although this Portfolio will not normally engage
      in short-term trading, purchases and sales of securities will be made
      whenever deemed appropriate to achieve the Portfolio's objective of a
      total return on its assets. The rate of portfolio turnover will not be a
      limiting factor when portfolio changes are deemed appropriate to achieve
      this Portfolio's stated objective. Under normal circumstances, the
      portfolio turnover rate for this portfolio is not expected to exceed 200%
      annually. The turnover rate for this portfolio was 22% in 1998.

      Capital Appreciation Portfolio - Although TRPA generally seeks less
      volatile securities for this Portfolio, the Portfolio may be traded fairly
      aggressively. Its portfolio turnover rate is normally expected to be 50%
      to 150% annually. The turnover rate for this portfolio was 45% in 1998.

      Small Cap Portfolio - While this Portfolio purchases and holds securities
      with the goal of meeting its investment objectives, portfolio changes are
      made whenever FAM believes they are advisable, usually

                                       7
<PAGE>   8
      without reference to the length of time a security has been held. The
      engagement in a substantial number of short-term transactions is expected
      to result in annual portfolio turnover rates of 100% to 300%. The turnover
      rate for this portfolio was 99% in 1998.

      International Small Company Portfolio - FGIM will not attempt to set or
      meet a portfolio turnover rate because turnover is incidental to
      transactions made in an attempt to achieve the Portfolio's investment
      objective. Securities will be sold whenever FGIM believes it is
      appropriate, regardless of how long they have been held. The turnover rate
      for this portfolio was 55% in 1998.

      Aggressive Growth Portfolio - The securities of this Portfolio are
      generally expected to be traded more aggressively than those of the other
      portfolios. Its portfolio turnover rate can normally be expected to be in
      the range of 100% to 300% annually. The turnover rate for this portfolio
      was 203% in 1998.


      Core Growth Portfolio - Although the securities held in this Portfolio are
      generally held for appreciation, PBA's disciplined response to its
      analytic process will occasionally result in sales without regard to the
      length of time a security has been held. The annual turnover rate is
      normally expected to be in the range of 150% to 350%. The turnover rate
      for this portfolio was 134 % in 1998.


      Growth & Income Portfolio - RSIM exercises "sell" disciplines. A stock
      held in this Portfolio is likely to be sold if it declines substantially
      in price (at least 15%), if it reaches its upside target price, if the
      company's business fundamentals turn negative, or if a more attractive
      opportunity appears. The prices of small- and mid-cap company securities
      in which this Portfolio invests may be more volatile than those of larger
      companies. As a result, the Portfolio's annual turnover rate is normally
      expected to be in the 100% to 300% range. The turnover rate for this
      portfolio was 286% in 1998.

      S&P 500 Index Portfolio - Securities held in this Portfolio generally will
      not be actively traded. Although it will often purchase fixed-income
      securities with relatively short maturities, those transactions are not
      expected to generate substantial brokerage commissions. The annual
      turnover rate is not normally expected to exceed 100%. The turnover rate
      for this portfolio was 115% in 1998.

      Social Awareness Portfolio - This Portfolio will not normally purchase
      securities with the intention of obtaining short-term returns. Under
      normal market conditions, the annual turnover rate is not expected to
      exceed 100%. The turnover rate for this portfolio was 71% in 1998.

      Strategic Income Portfolio - The securities of this Portfolio will
      generally be traded more frequently than those of the other income
      oriented portfolios. Its portfolio turnover rate can normally be expected
      to be in the range of 50% to 250% annually. The turnover rate for this
      portfolio was 104% in 1998.

      Firstar Growth & Income Portfolio - Although this Portfolio does not seek
      short-term profits, its securities will be sold whenever Firmco believes
      it is appropriate to do so in light of the Portfolio's investment
      objective without regard to the length of time a particular security may
      have been held. Its portfolio turnover rate is normally expected to be 50%
      to 150%. The turnover rate for this portfolio was 81% in 1998.

      Relative Value Portfolio - Although this Portfolio does not seek
      short-term profits, its securities will be sold whenever Star believes it
      is appropriate to do so in light of the Portfolio's investment objective
      without regard to the length of time a particular security may have been
      held. Its portfolio turnover rate is not expected to exceed 75% during
      normal economic and market conditions. The turnover rate for this
      portfolio was 54% in 1998.


      Capital Growth Portfolio - Securities held in this Portfolio tend to be
      actively traded. Its portfolio turnover rate is normally expected to
      exceed 100%. The turnover rate was 121% in 1998.


      High Income Bond Portfolio - The rate of portfolio turnover will vary from
      time to time, but it is not normally expected to exceed 100% for this
      Portfolio. The turnover rate was 11% in 1998.

      Equity Income Portfolio - The portfolio turnover rate for this Portfolio
      is normally expected to be in the range of 50% to 150% annually. The
      turnover rate was 38% in 1998.

                                       8
<PAGE>   9

      Blue Chip Portfolio - The Portfolio will not engage in short-term trading,
      but it may dispose of securities held for a short period if, after
      examination of their value, the sub-adviser believes such disposition to
      be advisable in order to attain the Portfolio's investment objective. The
      annual turnover rate is not normally expected to exceed 100%. The turnover
      rate was 32% in 1998.


                       INVESTMENT OBJECTIVES AND POLICIES

The following descriptions of money market instruments supplement the
"Investment Objectives and Policies" set forth for each portfolio in the
prospectus. The Money Market Portfolio and the Omni and Strategic Income
Portfolios, to the extent they invest in the money market sector, will invest
extensively in these instruments. The other Portfolios may invest in such
instruments to a limited extent (to invest otherwise idle cash) or on a
temporary basis for defensive purposes. The debt security ratings referred to in
the prospectus in connection with the investment policies of the portfolios are
defined in the Appendix to this Statement of Additional Information.


MONEY MARKET INSTRUMENTS

      U.S. Government Obligations - Bills, notes, bonds and other debt
      securities issued or guaranteed as to principal or interest by the United
      States or by agencies or authorities controlled or supervised by and
      acting as instrumentalities of the U.S. Government established under
      authority granted by Congress, including, but not limited to, the
      Government National Mortgage Association, the Tennessee Valley Authority,
      the Bank for Cooperatives, the Farmers Home Administration, and Federal
      Home Loan Banks. Some obligations of U.S. Government agencies, authorities
      and other instrumentalities are supported by the full faith and credit of
      the U.S. Treasury; others by the right of the issuer to borrow from the
      Treasury; and others only by the credit of the issuer. Certain of the
      foregoing may be purchased on a "when issued" basis at which time the rate
      of return will not have been set.

      Certificates of Deposit - Certificates issued against funds deposited in a
      bank for a definite period of time, at a specified rate of return.
      Normally they are negotiable.

      Bankers' Acceptances - Short-term credit instruments issued by
      corporations to finance the import, export, transfer or storage of goods.
      They are termed "accepted" when a bank guarantees their payment at
      maturity and reflect the obligation of both the bank and drawer to pay the
      face amount of the instrument at maturity.

      Commercial Paper - Promissory notes issued by corporations to finance
      their short-term credit needs. Commercial paper obligations may include
      variable amount master demand notes. Variable amount master demand notes
      are obligations that permit the investment of fluctuating amounts by the
      Portfolio at varying rates of interest pursuant to direct arrangements
      between the Portfolio, as lender, and the borrower. These notes permit
      daily changes in the amounts borrowed. The Portfolio has the right to
      increase the amount under the note at any time up to the full amount
      provided by the note agreement, or to decrease the amount, and the
      borrower may prepay up to the full amount of the note without penalty.
      Because variable amount master demand notes are direct lending
      arrangements between the lender and the borrower, it is not generally
      contemplated that such instruments will be traded, and there is no
      secondary market for these notes, although they are redeemable (and thus
      immediately repayable by the borrower) at face value, plus accrued
      interest, at any time. In connection with a master demand note
      arrangement, the Adviser will monitor, on an ongoing basis, the earning
      power, cash flow, and other liquidity ratios of the issuer, and the
      borrower's ability to pay principal and interest on demand. While master
      demand notes, as such, are not typically rated by credit rating agencies,
      if not so rated the Portfolio may invest in them only if at the time of an
      investment the issuer meets the criteria set forth above for all other
      commercial paper issuers. Such notes will be considered to have a maturity
      of the longer of the demand period or the period of the interest
      guarantee.

      Corporate Obligations - Bonds and notes issued by corporations in order to
      finance longer-term credit needs.



                                       9
<PAGE>   10
      Repurchase Agreements - Agreements by which the Portfolio purchases a
      security and obtains a simultaneous commitment from the seller (a member
      bank of the Federal Reserve System or a government securities dealer
      recognized by the Federal Reserve Board) to repurchase the security at a
      mutually agreed upon price and date. It may also be viewed as a loan of
      money by the Portfolio to the seller. The resale price is normally in
      excess of the purchase price and reflects an agreed upon market rate. The
      term of these repurchase agreements will generally be short, from
      overnight to one week, and at no time more than one year.


                             INVESTMENT RESTRICTIONS


The prospectus lists the most significant investment restrictions to which the
Fund is subject. The following is a complete list of the Fund's investment
restrictions. Except as otherwise specified, investment restrictions stated in
the prospectus and this Statement of Additional Information are fundamental
policies. Restrictions number 4, 7, 8, 12 and 13 are fundamental policies of the
Money Market, Bond and Omni Portfolios and nonfundamental as to the remaining
portfolios. The fundamental policies and nonfundamental operating policies of
the International, International Small Company, Capital Appreciation, Aggressive
Growth, High Income Bond, Equity Income and Blue Chip Portfolios are shown
separately below. Fundamental policies may not be changed without the
affirmative vote of the majority of the outstanding voting securities of the
Fund or a particular portfolio, as appropriate. The Investment Company Act of
l940 defines a majority vote as the vote of the lesser of (i) 67% of the shares
represented at a meeting at which more than 50% of the outstanding shares are
represented or (ii) more than 50% of the outstanding voting securities. With
respect to the submission of a change in an investment policy to the holders of
outstanding voting securities of a particular portfolio, such matter shall be
deemed to have been effectively acted upon with respect to such portfolio if a
majority of the outstanding voting securities of such portfolio vote for the
approval of such matter, notwithstanding (1) that such matter has not been
approved by the holders of a majority of the outstanding voting securities of
any other portfolio affected by such matter, and (2) that such matter has not
been approved by the vote of a majority of the outstanding voting securities of
the Fund.


The Fund may not issue senior securities and each portfolio of the Fund (other
than the International, International Small Company, Capital Appreciation,
Aggressive Growth, High Income Bond, Equity Income and Blue Chip Portfolios)
will not:

      l.      invest more than 5% of the value of the total assets of such
              portfolio in the securities of any one issuer (except U.S.
              government securities);

      2.      purchase more than l0% of the outstanding voting securities of any
              one issuer, and the Money Market Portfolio will not acquire the
              voting securities of any issuer except in connection with a
              merger, consolidation or other reorganization;

      3.      invest more than 25% of the value of its total assets in any one
              industry, except that each portfolio may invest more than 25% of
              the value of its total assets in obligations issued or guaranteed
              by the U.S. government, its agencies or instrumentalities or in
              certificates of deposit, bankers' acceptances, bank time deposits
              or other obligations of banks or financial institutions. However,
              it is the intention of management not to invest in time deposits
              which involve any penalty or other restriction on withdrawal;


      4.      invest more than 15% of the value of its assets (10% in the case
              of the Money Market, Bond and Omni Portfolios) in securities or
              other investments, including repurchase agreements maturing in
              more than seven days, that are subject to legal or contractual
              restrictions upon resale or are otherwise not readily marketable;

      5.      other than the Growth & Income, Strategic Income and Capital
              Growth Portfolios, borrow money, except for temporary or emergency
              purposes from banks, in which event the aggregate amount borrowed
              shall not exceed 5% of the value of the assets of the portfolio;
              in the case of such borrowing, each portfolio may pledge, mortgage
              or hypothecate up to 5% of its assets. Reverse repurchase
              agreements are not considered to be borrowed money for purposes of
              this restriction. The Growth & Income, Strategic Income and
              Capital Growth Portfolios may borrow money


                                       10
<PAGE>   11
              directly or through reverse repurchase agreements in amounts up to
              one-third of the value of each of their total net assets, other
              than the amount borrowed;

      6.      purchase or sell commodities or commodity contracts except that
              (a) each portfolio other than the Money Market Portfolio may, for
              hedging purposes, purchase and sell financial futures contracts
              and options thereon within the limits of investment restriction 7
              below, and (b) the S&P 500 Index Portfolio may purchase or sell

International, International Small Company, Capital Appreciation, Aggressive
Growth, High Income Bond, Equity Income and Blue Chip Portfolios, which policies
may be changed at any time by the vote of a majority of the Board of Directors,
each portfolio, in order to hedge against changes in the exchange rates of
foreign currencies in relation to the U.S. dollar, may engage in forward foreign
currency contracts, foreign currency options and foreign currency futures
contracts in connection with the purchase, sale or ownership of specific
securities (but, not more than 5% of a portfolio's assets may be invested in
such currency hedging contracts).

In addition to the above restrictions, in order to comply with Rule 2a-7 under
the Investment Company Act of 1940, no more than 5% of the assets of the Money
Market Portfolio will be invested in "second-tier" short-term debt instruments,
that is those receiving the second highest rating by any two nationally
recognized statistical rating organizations ("NRSRO's") and not receiving the
highest rating from more than one NRSRO (or receiving the second highest rating
from one NRSRO if (a) that is the only NRSRO having rated the security or (b)
one other NRSRO has given the security its highest rating), or whose issuer has
received such a rating or ratings with respect to a class of short-term debt
obligations that is now comparable in priority and security to those to be
purchased. In addition, not more than $1 million (or 1% of this portfolio's
assets, if greater) may be invested in the second-tier instruments of any one
issuer.


INTERNATIONAL, INTERNATIONAL SMALL COMPANY, HIGH INCOME BOND, EQUITY INCOME AND
BLUE CHIP PORTFOLIO FUNDAMENTAL POLICIES

As a matter of fundamental policy:

F.I.1    The portfolios will not issue senior securities, except that a
         portfolio may borrow money directly or through reverse repurchase
         agreements in amounts not in excess of one-third of the value of its
         total assets; provided that, while borrowings and reverse repurchase
         agreements outstanding exceed 5% of a portfolio's total assets, any
         such borrowings will be repaid before additional investments are made.

F.I.2.   The portfolios will not purchase securities if, as a result of such
         purchase, 25% or more of a portfolio's total assets would be invested
         in any one industry. However, a portfolio may at any time invest 25% or
         more of its total assets in cash or cash items and securities issued
         and/or guaranteed by the U.S. government, its agencies or
         instrumentalities.

F.I.3.   The portfolios will not purchase or sell real estate, although they may
         invest in securities of companies whose business involves the purchase
         or sale of real estate or in securities secured by real estate or
         interests in real estate.

F.I.4.   The portfolios will not lend any of their assets, except a portfolio's
         securities, up to one-third of its total assets. This shall not prevent
         a portfolio from purchasing or holding corporate or U.S. government
         bonds, debentures, notes, certificates of indebtedness or other debt
         securities of an issuer, entering into repurchase agreements, or
         engaging in other transactions which are permitted by the portfolio's
         investment objectives and policies.




                                       12
<PAGE>   13

F.I.5.   The portfolios will not underwrite any issue of securities, except as a
         portfolio may be deemed to be an underwriter under the Securities Act
         of 1933 in connection with the sale of securities in accordance with
         its investment objectives, policies, and limitations.

F.I.6.   With respect to 75% of its total assets, a portfolio will not purchase
         the securities of any one issuer (other than cash, cash items, or
         securities issued and/or guaranteed by the U.S. government, its
         agencies or instrumentalities, and repurchase agreements collateralized
         by such securities) if, as a result, more than 5% of its total assets
         would be invested in the securities of that issuer. Also, a portfolio
         will not purchase more than 10% of any class of the outstanding voting
         securities of any one issuer. For these purposes, the portfolios
         consider common stock and all preferred stock of an issuer each as a
         single class, regardless of priorities, series, designations, or other
         differences.

F.I.7.   The portfolios will not purchase any securities on margin, but they may
         obtain such short-term credits as are necessary for clearance of
         transactions. The deposit or payment by a portfolio of initial or
         variation margin in connection with financial futures contracts or
         related options transactions is not considered the purchase of a
         security on margin.

F.I.8.   The portfolios will not purchase or sell commodities, except that a
         portfolio may purchase and sell financial futures contracts and related
         options.

         of its total assets at the time of borrowing.

F.I.10.  The portfolios will not sell securities short unless during the time
         the short position is open, a portfolio owns an equal amount of the
         securities sold or securities readily and freely convertible into or
         exchangeable, without payment of additional consideration, for
         securities of the same issue as, and equal in amount to, the securities
         sold short; and not more than 10% of a portfolio's net assets (taken at
         current value) is held as collateral for such sales at any one time.

         in illiquid securities, including, among others, repurchase agreements
         providing for settlement more than seven days after notice, and certain
         restricted securities not determined by the Board of Directors to be
         liquid.

      C.A.21.        Invest more than 25% of the Portfolio's total assets
                     (excluding reserves) in foreign securities.

AGGRESSIVE GROWTH PORTFOLIO FUNDAMENTAL POLICIES

As a matter of fundamental policy, the Portfolio:

      A.G.1.         May not with respect to 75% of its total assets, purchase
                     the securities of any issuer (except securities issued or
                     guaranteed by the U.S. government or its agencies or
                     instrumentalities) if, as a result, (i) more than 5% of the
                     Portfolio's total assets would be invested in the
                     securities of that issuer, or (ii) the Portfolio would hold
                     more than 10% of the outstanding voting securities of that
                     issuer.

      A.G.2.         May (i) borrow money from banks and (ii) make other
                     investments or engage in other transactions permissible
                     under the Investment Company Act of 1940 which may involve
                     a borrowing, provided that the combination of (i) and (ii)
                     shall not exceed 33-1/3% of the value of the Portfolio's
                     total assets (including the amount borrowed), less the
                     Portfolio's liabilities (other than borrowings), except
                     that the Portfolio 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 Portfolio may
                     also borrow money from the other mutual funds managed by
                     SCM or other persons to the extent permitted by applicable
                     law.

      A.G.3.         May not issue senior securities, except as permitted under
                     the Investment Company Act of 1940.

      A.G.4.         May not act as an underwriter of another issuer's
                     securities, except to the extent that the Portfolio may be
                     deemed to be an underwriter within the meaning of the
                     Securities Act of 1933 in connection with the purchase and
                     sale of portfolio securities.

      A.G.5.         May not purchase or sell physical commodities unless
                     acquired as a result of ownership of securities or other
                     instruments (but this shall not prevent the Portfolio from
                     purchasing or selling options, futures contracts, or other
                     derivative instruments, or from investing in securities or
                     other instruments backed by physical commodities).

      A.G.6.         May not make loans if, as a result, more than 33-1/3% of
                     the Portfolio's total assets would be lent to other
                     persons, except through (i) purchases of debt securities or
                     other debt instruments, or (ii) engaging in repurchase
                     agreements.

      A.G.7.         May not purchase the securities of any issuer if, as a
                     result, more that 25% of the Portfolio's total assets would
                     be invested in the securities of issuers, the principal
                     business activities of which are in the same industry.

      A.G.8.         May not purchase or sell real estate unless acquired as a
                     result of ownership of securities or other instruments (but
                     this shall not prohibit the Portfolio from purchasing or
                     selling securities or other instruments backed by real
                     estate or of issuers engaged in real estate activities).


AGGRESSIVE GROWTH PORTFOLIO NONFUNDAMENTAL OPERATING POLICIES

As a matter of nonfundamental operating policy, the Portfolio may not:

      A.G.9.         Sell securities short, unless the Portfolio owns or has
                     the right to obtain securities equivalent in kind and
                     amount to the securities sold short, or unless it covers
                     such short sale as required by the current rules and
                     positions of the SEC or its staff, and provided that
                     transactions in options, futures contracts, options on
                     futures contracts, or other derivative instruments are not
                     deemed to constitute selling securities short.

      A.G.10.        Purchase securities on margin, except that the Portfolio
                     may obtain such short-term credits as are necessary for the
                     clearance of transactions; and provided that margin
                     deposits in


                                       16
<PAGE>   17

                     connection with futures contacts, options on futures
                     contracts, or other derivative instruments shall not
                     constitute purchasing securities on margin.

      A.G.11.        Invest in illiquid securities if, as a result of such
                     investment, more than 15% of its net assets would be
                     invested in illiquid securities, or such other amounts as
                     may be permitted under the Investment Company Act of 1940.

      A.G.12.        Purchase securities of other investment companies except in
                     compliance with the Investment Company Act of 1940 and
                     applicable state law.

      A.G.13.        Purchase the securities of any issuer (other than
                     securities issued or guaranteed by domestic or foreign
                     governments or political subdivisions thereof) if, as a
                     result, more than 5% of its total assets would be invested
                     in the securities of issuers that, including predecessor or
                     unconditional guarantors, have a record of less than three
                     years of continuous operation. This policy does not apply
                     to securities of pooled investment vehicles or mortgage or
                     asset-backed securities.

      A.G.14.        Invest in direct interests in oil, gas, or other mineral
                     exploration programs or leases; however, the Portfolio may
                     invest in the securities of issuers that engage in these
                     activities.

      A.G.15.        Engage in futures or options on futures transactions which
                     are impermissible pursuant to Rule 4.5 under the Commodity
                     Exchange Act and, in accordance with Rule 4.5, will use
                     futures or options on futures transactions solely for bona
                     fide hedging transactions (within the meaning of the
                     Commodity Exchange Act), provided, however, that the
                     Portfolio may, in addition to bona fide hedging
                     transactions, use futures and options on futures
                     transactions if the aggregate initial margin and premiums
                     required to establish such positions, less the amount by
                     which any such options positions are in the money (within
                     the meaning of the Commodity Exchange Act), do not exceed
                     5% of the Portfolio's net assets.

                     In addition, (i) the aggregate value of securities
                     underlying call options on securities written by the
                     Portfolio or obligations underlying put options on
                     securities written by the Portfolio determined as of the
                     date the options are written will not exceed 50% of the
                     Portfolio's net assets; (ii) the aggregate premiums paid on
                     all options purchased by the Portfolio and which are being
                     held will not exceed 20% of the Portfolio's net assets;
                     (iii) the Portfolio will not purchase put or call options,
                     other than hedging positions, if, as a result thereof, more
                     than 5% of its total assets would be so invested; and (iv)
                     the aggregate margin deposits required on all futures and
                     options on futures transactions being held will not exceed
                     5% of the Portfolio's total assets.

      A.G.16.        Pledge, mortgage or hypothecate any assets owned by the
                     Portfolio except as may be necessary in connection with
                     permissible borrowings or investments and then such
                     pledging, mortgaging, or hypothecating may not exceed
                     33-1/3% of the Portfolio's total assets at the time of the
                     borrowing or investment.

      A.G.17.        Purchase warrants, valued at the lower of cost or market
                     value, in excess of 5% of the Portfolio's net assets.
                     Included in that amount, but not to exceed 2% of the
                     Portfolio's net assets, may be warrants that are not listed
                     on the New York Stock Exchange or the American Stock
                     Exchange. Warrants acquired by the Portfolio in units or
                     attached to securities are not subject to these
                     restrictions.

      A.G.18.        Borrow money except (i) from banks or (ii) through reverse
                     repurchase agreements or mortgage dollar rolls, and will
                     not purchase securities when bank borrowings exceed 5% of
                     its total assets.

      A.G.19.        Make any loans other than loans of portfolio securities,
                     except through (i) purchases of debt securities or other
                     debt instruments, or (ii) engaging in repurchase
                     agreements.

INTERNATIONAL, INTERNATIONAL SMALL COMPANY, HIGH INCOME BOND, EQUITY INCOME AND
BLUE CHIP PORTFOLIO FUNDAMENTAL POLICIES

As a matter of fundamental policy:

F.I.1    The portfolios will not issue senior securities, except that a
         portfolio may borrow money directly or through reverse repurchase
         agreements in amounts not in excess of one-third of the value of its
         total assets; provided that, while borrowings and reverse repurchase
         agreements outstanding exceed 5% of a portfolio's total assets, any
         such borrowings will be repaid before additional investments are made.

F.I.2.   The portfolios will not purchase securities if, as a result of such
         purchase, 25% or more of a portfolio's total assets would be invested
         in any one industry. However, a portfolio may at any time invest 25% or
         more of its total assets in cash or cash items and securities issued
         and/or guaranteed by the U.S. government, its agencies or
         instrumentalities.

F.I.3.   The portfolios will not purchase or sell real estate, although they may
         invest in securities of companies whose business involves the purchase
         or sale of real estate or in securities secured by real estate or
         interests in real estate.

F.I.4.   The portfolios will not lend any of their assets, except a portfolio's
         securities, up to one-third of its total assets. This shall not prevent
         a portfolio from purchasing or holding corporate or U.S. government
         bonds, debentures, notes, certificates of indebtedness or other debt
         securities of an issuer, entering into repurchase agreements, or
         engaging in other transactions which are permitted by the portfolio's
         investment objectives and policies.

F.I.5.   The portfolios will not underwrite any issue of securities, except as a
         portfolio may be deemed to be an underwriter under the Securities Act
         of 1933 in connection with the sale of securities in accordance with
         its investment objectives, policies, and limitations.

F.I.6.   With respect to 75% of its total assets, a portfolio will not purchase
         the securities of any one issuer (other than cash, cash items, or
         securities issued and/or guaranteed by the U.S. government, its
         agencies or instrumentalities, and repurchase agreements collateralized
         by such securities) if, as a result, more than 5% of its total assets
         would be invested in the securities of that issuer. Also, a portfolio
         will not purchase more than 10% of any class of the outstanding voting
         securities of any one issuer. For these purposes, the portfolios
         consider common stock and all preferred stock of an issuer each as a
         single class, regardless of priorities, series, designations, or other
         differences.

F.I.7.   The portfolios will not purchase any securities on margin, but they may
         obtain such short-term credits as are necessary for clearance of
         transactions. The deposit or payment by a portfolio of initial or
         variation margin in connection with financial futures contracts or
         related options transactions is not considered the purchase of a
         security on margin.

F.I.8.   The portfolios will not purchase or sell commodities, except that a
         portfolio may purchase and sell financial futures contracts and related
         options.


INTERNATIONAL, INTERNATIONAL SMALL COMPANY, HIGH INCOME BOND, EQUITY INCOME AND
BLUE CHIP PORTFOLIO NONFUNDAMENTAL OPERATING POLICIES

As a matter of nonfundamental operating policy:

F.I.9.   The portfolios will not pledge, mortgage or hypothecate any assets
         except to secure permitted borrowings. In those cases, a portfolio may
         pledge, mortgage or hypothecate assets having a


                                       18
<PAGE>   19

         market value not exceeding the lesser of the dollar amounts borrowed or
         15% of the value of its total assets at the time of borrowing.

F.I.10.  The portfolios will not sell securities short unless during the time
         the short position is open, a portfolio owns an equal amount of the
         securities sold or securities readily and freely convertible into or
         exchangeable, without payment of additional consideration, for
         securities of the same issue as, and equal in amount to, the securities
         sold short; and not more than 10% of a portfolio's net assets (taken at
         current value) is held as collateral for such sales at any one time.

F.I.11.  Each of the portfolios will not invest more than 15% of its net assets
         in illiquid securities, including, among others, repurchase agreements
         providing for settlement more than seven days after notice, and certain
         restricted securities not determined by the Board of Directors to be
         liquid.


HEDGING TRANSACTIONS

The purpose of hedging transactions using put and call options on individual
securities, financial futures contracts, and options on such contracts and on
financial indexes, all to the extent provided in investment restriction 7, is to
reduce the risk of fluctuation of portfolio securities values or to take
advantage of expected market fluctuations. However, while such transactions are
defensive in nature and are not speculative, some risks remain.

The use of options and futures contracts may help the Fund to gain exposure or
to protect itself from changes in market values. For example, the Fund may have
a substantial amount of cash at the beginning of a market rally. Conventional
procedures of purchasing a number of individual issues requires time and may
result in missing a significant market movement. By using futures contracts, the
Fund can obtain immediate exposure to the market.

The buying program will then proceed and, once it is completed (or as it
proceeds), the futures contracts will be closed. Conversely, in the early stages
of a market decline, market exposure can be promptly offset by selling futures
contracts, and individual securities can be sold over a longer period under
cover of the resulting short contract position.


COVERED CALL OPTIONS AND PUT OPTIONS

In writing (i.e., selling) "covered" call options on securities owned by a
portfolio, the portfolio gives the purchaser of the call option the right to
purchase the underlying securities owned by the portfolio at a specified
"exercise" price at any time prior to the expiration of the option, normally
within nine months. In purchasing put options on securities owned by a
portfolio, the portfolio pays the seller of the put option a premium for the
right of the portfolio to sell the underlying securities owned by the portfolio
at a specified exercise price prior to the expiration of the option.

Whenever a portfolio has a covered call option outstanding, the underlying
securities will be segregated by the Custodian and held in an escrow account to
assure that such securities will be delivered to the option holder if the option
is exercised. While the underlying securities are subject to the option, the
portfolio remains the record owner of the securities, entitling it to receive
dividends and to exercise any voting rights.

In order to terminate its position as the writer of a call option or the
purchaser of a put option, the portfolio may enter into a "closing" transaction,
which is the purchase of a call option or sale of a put option on the same
underlying securities and having the same exercise price and expiration date as
the option previously sold or purchased by the portfolio.

FUTURES CONTRACTS

The Fund may invest in two kinds of financial futures contracts: stock index
futures contracts and interest rate futures contracts. Stock index futures
contracts are contracts developed by and traded on national commodity exchanges
whereby the buyer will, on a specified future date, pay or receive a final cash
payment equal to the difference between the actual value of the stock index on
the last day of the contract and the value of the stock index established by the
contract multiplied by the specific dollar amount set by the exchange. Futures
contracts may be based on broad-based stock indexes such as the S&P 500 or on
narrow-based stock indexes. A particular index will be selected according to the
Adviser's investment strategy for the particular portfolio. An interest rate
futures contract is an agreement whereby one party agrees to sell and another
party agrees to purchase a specified amount of a specified financial instrument
(debt security) at a specified price at a specified date, time and place.
Although interest rate futures contracts typically require actual future
delivery of and payment for financial instruments, the contracts are usually
closed out before the delivery date. A public market exists in interest rate
futures contracts covering primarily the following financial instruments: U.S.
Treasury bonds; U.S. Treasury notes; Government National Mortgage Association
(GNMA) modified pass-through mortgage-backed securities; three-month U.S.
Treasury bills; 90-day commercial paper; bank certificates of deposit; and
Eurodollar certificates of deposit. It is expected that futures contracts
trading in additional financial instruments will be authorized.

At the time the Fund enters into a contract, it sets aside a small portion of
the contract value in an account with the Fund's custodian as a good faith
deposit (initial margin) and each day during the contract period requests and
receives or pays cash equal to the daily change in the contract value (variable
margin). The Fund, its futures commission merchant and the Fund's custodian
retain control of the initial margin until the contract is liquidated.


OPTIONS ON FUTURES CONTRACTS AND FINANCIAL INDEXES

Instead of entering into a financial futures contract, the Fund may buy an
option giving it the right to enter into such a contract at a future date. The
price paid for such an option is called a premium. The Fund also may buy options
on financial indexes that are traded on securities exchanges. Options on
financial indexes react to changes in the value of the underlying index in the
same way that options on financial futures contracts do. All settlements for
options on financial indexes also are for cash.

Financial futures contracts, options on such contracts and options on financial
indexes will only be used for hedging purposes and will, therefore, be
incidental to the Fund's activities in the securities market. Accordingly,
portfolio securities subject to options, or money market instruments having the
market value of any futures contracts, generally will be set aside to
collateralize the options or futures contracts.


FOREIGN CURRENCY HEDGING TRANSACTIONS

In order to hedge against changes in the exchange rates of foreign currencies in
relation to the U.S. dollar, each portfolio, other than the Money Market
Portfolio, may engage in forward foreign currency contracts, foreign currency
options and foreign currency futures contracts in connection with the purchase,
sale or ownership of a specific security.

The portfolios generally conduct their foreign currency exchange transactions on
a spot (i.e., cash) basis at the spot rate prevailing in the foreign exchange
currency market. When a portfolio purchases or sells a security denominated in a
foreign currency, it may enter into a forward foreign currency contract
("forward contract") for the purchase or sale, for a fixed amount of dollars, of
the amount of currency involved in the underlying security transaction. A
forward 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.
In this manner, a portfolio may obtain protection against a possible loss
resulting from an adverse change in the relationship between the U.S. dollar and
the foreign currency during the period between the date the security is
purchased or sold and the date upon which payment is made or received. Although
such contracts tend to minimize the risk of loss due to the decline in the value
of




                                       20
<PAGE>   21



the hedged currency, at the same time they tend to limit any potential gain
which might result should the value of such currency increase.

Forward contracts are traded in the interbank market conducted directly between
currency traders (usually large commercial banks) and their customers. Generally
a forward contract has no deposit requirement, and no commissions are charged.
Although foreign exchange dealers do not charge a fee for conversion, they do
realize a profit based on the difference between the prices at which they buy
and sell various currencies. When the portfolio manager believes that the
currency of a particular foreign country may suffer a substantial decline
against the U.S. dollar, a portfolio may enter into a forward contract to sell,
for a fixed amount of dollars, the amount of foreign currency approximating the
value of some or all of that portfolio's securities denominated in such foreign
currency. No portfolio will enter into such forward contracts or maintain a net
exposure to such contracts where the consummation of the contracts would
obligate the portfolio to deliver an amount of foreign currency in excess of the
value of its assets denominated in that currency.

At the consummation of a forward contract for delivery by a portfolio of a
foreign currency, the portfolio may either make delivery of the foreign currency
or terminate its contractual obligation to deliver the foreign currency by
purchasing an offsetting contract obligating it to purchase, at the same
maturity date, the same amount of the foreign currency. If the portfolio chooses
to make delivery of the foreign currency, it may be required to obtain such
currency through the sale of its securities denominated in such currency or
through conversion of other portfolio assets into such currency. It is
impossible to forecast the market value of portfolio securities at the
expiration of the forward contract. Accordingly, it may be necessary for the
portfolio to purchase additional foreign currency on the spot market (and bear
the expense of such purchase) if the market value of the security is less than
the amount of foreign currency the portfolio is obligated to deliver, and if a
decision is made to sell the security and make delivery of the foreign currency.
Conversely, it may be necessary for the portfolio to sell on the spot market
some of the foreign currency received on the sale of its hedged security if the
security's market value exceeds the amount of foreign currency the portfolio is
obligated to deliver.

If the portfolio retains the hedged security and engages in an offsetting
transaction, it will incur a gain or loss to the extent that there has been
movement in spot or forward contract prices. If a portfolio engages in an
offsetting transaction, it may subsequently enter into a new forward contract to
sell the foreign currency. Should forward prices decline during the period
between the portfolio's entering into a forward contract for the sale of a
foreign currency and the date it enters into an offsetting contract for the
purchase of the foreign currency, the portfolio will realize a gain to the
extent the price of the currency it has agreed to sell exceeds the price of the
currency it has agreed to purchase. Should forward prices increase, the
portfolio will suffer a loss to the extent the price of the currency it has
agreed to purchase exceeds the price of the currency it has agreed to sell.

Buyers and sellers of foreign currency options and futures contracts are subject
to the same risks previously described with respect to options and futures
generally (see "Risk Factors with Options" and "Risk Factors with Futures,
Options on Futures and Options on Indexes," above). In addition, settlement of
currency options and futures contracts with respect to most currencies must
occur at a bank located in the issuing nation. The ability to establish and
close out positions on such options is subject to the maintenance of a liquid
market that may not always be available. Currency rates may fluctuate based on
political considerations and governmental actions as opposed to purely economic
factors.

Predicting the movements of foreign currency in relation to the U.S. dollar is
difficult and requires different skills than those necessary to predict
movements in the securities market. There is no assurance that the use of
foreign currency hedging transactions can successfully protect a portfolio
against loss resulting from the movements of foreign currency in relation to the
U.S. dollar. In addition, it must be remembered that these methods of protecting
the value of a portfolio's securities against a decline in the value of a
currency does not eliminate fluctuations in the underlying prices of the
securities. It simply establishes a rate of exchange which can be achieved at
some future point in time. Additionally, although such contracts tend to
minimize the risk of loss due to the decline in the value of the hedged
currency, at the same time they tend to limit any potential gain which might
result should the value of such currency increase.

HYBRID INSTRUMENTS

Hybrid instruments are potentially high-risk derivatives. They can combine the
characteristics of securities, futures and options. For example, the principal
amount, redemption or conversion terms of a security could be related to the
market price of some commodity, currency or futures index. Hybrid instruments
may bear interest or pay dividends at or below market or even relatively
nominal rates. Under certain conditions, the redemption value of an investment
could be zero. The Capital Appreciation portfolio may invest up to 10% of its
total assets in hybrid instruments.

SWAPS

Swaps are contracts in which two parties agree to pay each other (swap) the
returns derived from underlying assets with differing characteristics. Most
swaps do not involve the delivery of the underlying assets by either party, and
the parties might not even own the assets underlying the swap. The payments are
usually made on a net basis so that, on any given day, the portfolio would
receive (or pay) only the amount by which its payment under the contract is
less than (or exceeds) the amount of the other party's payment. Swap agreements
are sophisticated derivative instruments that can take many forms. They are
known by a variety of names including caps, floors and collars.

Interest rate swaps are contracts in which one party agrees to make regular
payments equal to a fixed or floating interest rate times a stated principal
amount of fixed income securities in return for payments equal to a different
fixed or floating rate, times the same principal amount, for a specified
period. For example, a $10 million LIBOR swap would require one party to pay to
the other party the equivalent of the London Interbank Offer Rate of interest
(which fluctuates) on $10 million principal amount in exchange for the right to
receive the equivalent of a stated fixed rate of interest on a $10 million
principal amount.

Currency swaps are contracts which provide for interest payments in different
currencies. The parties might agree to exchange the notional principal amount as
well.

Caps and Floors are contracts in which one party agrees to make payments only if
an interest rate or index goes above (Cap) or below (Floor) a certain level
in return for a fee from the other party.

SHORT SALES

Until a borrowed security borrowed in connection with a short sale (as described
in the prospectus) is replaced, a portfolio will be required to maintain daily a
segregated account, containing cash or U.S. government securities, at such a
level that (i) the amount deposited in the account plus the amount deposited
with the broker as collateral will at all times be equal to at least 100% of the
current value of the security sold short and (ii) the amount deposited in the
segregated account plus the amount deposited with the broker as collateral will
not be less than the market value of the security at the time it was sold short.
A portfolio may purchase call options to provide a hedge against an increase in
the price of a security sold short. When a portfolio purchases a call option, it
has to pay a premium to the person writing the option and a commission to the
broker selling the option. If the option is exercised by a portfolio, the
premium and the commission paid may be more than the amount of the brokerage
commission charged if the security were to be purchased directly. See "Hedging
Transactions" and "Covered Call Options and Put Options." In addition to the
short sales discussed above, a portfolio also may make short sales "against the
box," a transaction in which a portfolio enters into a short sale of a security
which the portfolio owns. The proceeds of the short sale are held by a broker
until the settlement date, at which time the portfolio delivers the security to
close the short position. A portfolio receives the net proceeds from the short
sale. No portfolio will, at any time, have more than 5% of the value of its net
assets in deposits on short sales against the box.


BORROWING MONEY

The portfolios will not borrow money except as a temporary measure for
extraordinary or emergency purposes and then only in amounts not in excess of 5%
of the value of a portfolio's total assets. In addition, certain portfolios may
enter into reverse repurchase agreements and otherwise borrow up to one-third of
the value of the portfolio's total assets, including the amount borrowed, in
order to meet redemption requests without immediately selling portfolio
securities. This latter practice is not for investment leverage but solely to
facilitate management of a portfolio by enabling it to meet redemption requests
when the liquidation of portfolio instruments would be inconvenient or
disadvantageous.

Interest paid on borrowed funds will not be available for investment and will
reduce net income. A portfolio will liquidate any such borrowings as soon as
possible and may not purchase any portfolio securities while the borrowings are
outstanding. However, during the period any reverse repurchase agreements are
outstanding, but only to the extent necessary to assure completion of the
reverse repurchase agreements, the purchase of portfolio securities will be
limited to money market instruments maturing on or before the expiration date of
the reverse repurchase agreements.


ZERO-COUPON AND PAY-IN-KIND DEBT SECURITIES

Zero-coupon securities (or "step ups") in which a portfolio may invest are debt
obligations which are generally issued at a discount and payable in full at
maturity, and which do not provide for current payments of interest prior to
maturity. Pay-in-kind securities make periodic interest payments in the form of
additional securities (as opposed to cash). Zero-coupon and pay-in-kind
securities usually trade at a deep discount from their face or par value and are
subject to greater market value fluctuations from changing interest rates than
debt obligations of comparable maturities which make current distributions of
interest. As a result, the net asset value of shares of a portfolio investing in
zero-coupon and pay-in-kind securities may fluctuate over a greater range than
shares of other mutual funds investing in securities making current
distributions of interest and having similar maturities.

When debt obligations have been stripped of their unmatured interest coupons by
the holder, the stripped coupons are sold separately. The principal or corpus is
sold at a deep discount because the buyer receives only the right to receive a
future fixed payment on the security and does not receive any rights to periodic
cash interest payments. Once stripped or separated, the corpus and coupons may
be sold separately. Typically, the coupons are sold separately or grouped with
other coupons with like maturity dates and sold in such bundled form. Purchasers
of stripped obligations acquire, in effect, discount obligations that are
economically identical to the zero-coupon securities issued directly by the
obligor.



                                       22
<PAGE>   23


Zero-coupon convertible securities are debt instruments issued at a discount to
their face amount and convertible to common stock (see "Convertible Securities,"
above). These securities usually have put features giving the holder the
opportunity to sell them back to the issuer at a stated price prior to maturity.
The prices of zero-coupon convertible securities are generally more sensitive to
interest rate fluctuations than are conventional convertible securities.

Zero-coupon securities allow an issuer to avoid the need to generate cash to
meet current interest payments. Even though zero-coupon securities do not pay
current interest in cash, federal income tax law requires zero-coupon holders to
recognize accrued income prior to receipt of actual cash payment (i.e., at
maturity). In order to avoid federal income tax liability and maintain its
status as a regulated investment company, a portfolio may have to sell these
securities at disadvantageous times in order to generate cash for the
distribution of accrued income.

INVESTMENT ADVISORY AND OTHER SERVICES

The Adviser is an Ohio corporation organized on January 17, 1996 to provide
investment advice and management services to funds affiliated with ONLI. The
Adviser is a wholly-owned subsidiary of ONLI. The Adviser succeeded O.N.
Investment Management Company ("ONIMCO") as the Fund's investment adviser on May
1, 1996. Prior to that date, ONIMCO had been the investment adviser from the
Fund's inception. The Adviser, like ONIMCO before it, uses ONLI's investment
personnel and administrative systems.


The Adviser regularly furnishes to the Fund's Board of Directors recommendations
with respect to an investment program consistent with the investment policies of
each portfolio. Upon approval of an investment program by the Fund's Board of
Directors, the Adviser implements the program by placing the orders for the
purchase and sale of securities or, in the case of the International, Capital
Appreciation, Small Cap, International Small Company, Aggressive Growth, Core
Growth, Growth & Income, Strategic Income, Firstar Growth & Income, Relative
Value, Capital Growth, High Income Bond, Equity Income and Blue Chip Portfolios,
by delegating that implementation to LMFA, FGIM, TRPA, FAM, SCM, PBA, RSIM, FIC,
Firstar or Firmco as the case may be.


The Adviser's services are provided under an Investment Advisory Agreement with
the Fund. Under the Investment Advisory Agreement, the Adviser provides
personnel, including executive officers for the Fund. The Adviser also furnishes
at its own expense or pays the expenses of the Fund for clerical and related
administrative services (other than those provided by the custodian agreements
with Firstar and Investors Fiduciary Trust Company and an agency agreement with
American Data Services, Inc.), office space, and other facilities. The Fund pays
corporate expenses incurred in its operations, including, among others, local
income, franchise, issuance or other taxes; certain printing costs; brokerage
commissions on portfolio transactions; custodial and transfer agent fees;
auditing and legal expenses; and expenses relating to registration of its shares
for sale and shareholders' meetings.

As compensation for its services, the Adviser receives from the Fund annual fees
on the basis of each portfolio's average daily net assets during the month for
which the fees are paid based on the following schedule:


(a) for each of the Bond, Omni and Social Awareness Portfolios, 0.60% of the
first $100 million of each Portfolio's average daily net assets, 0.50% of the
next $150 million, 0.45% of the next $250 million, 0.40% of the next $500
million, 0.30% of the next $1 billion, and 0.25% of average daily net assets
over $2 billion;


(b) for the Money Market Portfolio, 0.30% of the first $100 million of average
daily net assets, 0.25% of the next $150 million, 0.23% of the next $250
million, 0.20% of the next $500 million, and 0.15% of average daily net assets
over $1 billion;


(c) for the International, Relative Value, Capital Growth and Blue Chip
Portfolios, 0.90% of each Portfolio's average daily net assets;


(d) for the Capital Appreciation, Small Cap, Aggressive Growth and Strategic
Income Portfolios, 0.80% of each Portfolio's average daily net assets,

(e) for the Core Growth Portfolio, 0.95% of the first $150 million of average
daily net assets, and 0.80% of average daily net assets over $150 million;

(f) for the Growth & Income Portfolio, 0.85% of the first $200 million of
average daily net assets, and 0.80% of average daily net assets over $200
million,

(g) for the S&P 500 Index Portfolio, 0.40% of the first $100 million of average
daily net assets, 0.35% of the next $150 million, and 0.33% of average daily net
assets over $250 million;

These agreements will continue in force from year to year if continuance is
specifically approved at least annually by a majority of the Fund's directors
who are not parties to such agreements or interested persons of any such party,
with votes to be cast in person at a meeting called for the purpose of voting on
such continuance, and also by a majority of the Board of Directors or by a
majority of the outstanding voting securities of each portfolio voting
separately.

The Investment Advisory, Service, and Sub-Advisory Agreements may be terminated
at any time, without the payment of any penalty, on 60 days' written notice to
the Adviser by the Fund's Board of Directors or, as to any portfolio, by a vote
of the majority of the portfolio's outstanding voting securities. The Investment
Advisory Agreement may be terminated by the Adviser on 90 days' written notice
to the Fund. The Service Agreement may be terminated, without penalty, by the
Adviser or ONLI on 90 days' written notice to the Fund and the other party. The
Sub-Advisory Agreements may be terminated, without penalty, by the Adviser or
the sub-adviser on 90 days' written notice to the Fund and the other party. The
Agreements will automatically terminate in the event of their assignment.

                              BROKERAGE ALLOCATION


The Adviser buys and sells the portfolio securities for the Money Market, Bond,
Omni, S&P 500 Index and Social Awareness Portfolios and selects the brokers and
dealers to handle such transactions. Each of the sub-advisers selects the
brokers and dealers that execute the transactions for the portfolios managed by
the respective sub-adviser. It is the intention of the Adviser and of each
sub-adviser to place orders for the purchase and sale of securities with the
objective of obtaining the most favorable price consistent with good brokerage
service. The cost of securities transactions for each portfolio will consist
primarily of brokerage commissions or dealer or underwriter spreads. Bonds and
money market securities are generally traded on a net basis and do not normally
involve either brokerage commissions or transfer taxes.


                                       28
<PAGE>   29
Occasionally, securities may be purchased directly from the issuer. For
securities traded primarily in the over-the-counter market, the Adviser and
sub-advisers will, where possible, deal directly with dealers who make a market
in the securities unless better prices and execution are available elsewhere.
Such dealers usually act as principals for their own account.

In selecting brokers or dealers through whom to effect transactions, the Adviser
and sub-advisers consider a number of factors including the quality, difficulty
and efficiency of execution, and value of research, statistical, quotation and
valuation services provided. Research services by brokers include advice, either
directly or through publications or writings, as to the value of securities, the
advisability of purchasing or selling securities, the availability of securities
or purchasers or sellers of securities, and analyses and reports concerning
issuers, industries, securities, economic factors and trends, and portfolio
strategy. In making such determination, the Adviser or sub-adviser may use a
broker whose commission in effecting a securities transaction is in excess of
that of some other broker if the Adviser or sub-adviser determines in good faith
that the amount of such commission is reasonable in relation to the value of the
research and related services provided by such broker. In effecting a
transaction for one portfolio, a broker may also offer services of benefit to
other portfolios managed by the Adviser or sub-adviser, or of benefit to its
affiliates.

Generally, it is not possible to place a dollar value on research and related
services provided by brokers to the Adviser or a sub-adviser. However, receipt
of such services may tend to reduce the expenses of the Adviser or the
sub-advisers. Research, statistical and similar information furnished by brokers
may be of incidental assistance to other clients of the Adviser or the
sub-advisers and conversely, transaction costs paid by other clients of the
Adviser or the sub-advisers may generate information which is beneficial to the
Fund.

Consistent with these policies, the sub-advisers may, with the Board of
Directors' approval and subject to its review, direct portfolio transactions to
be executed by a broker affiliated with the sub-adviser so long as the
commission paid to the affiliated broker is reasonable and fair compared to the
commission that would be charged by an unaffiliated broker in a comparable
transaction.

For each of the indicated years, ending on December 3l, the following brokerage
commission amounts were paid by each portfolio:

                        PURCHASE AND REDEMPTION OF SHARES

Fund shares are sold without a sales charge and may be redeemed at their net
asset value next computed after a purchase or redemption order is received by
the Fund. (The net asset value for the Money Market Portfolio is normally $l0
per share.) Depending upon the net asset values at that time, the amount paid
upon redemption may be more or less than the cost of the shares redeemed.
Payment for shares redeemed will be made as soon as possible, but in any event
within seven days after evidence of ownership of the shares is tendered to the
Fund. However, the Fund may suspend the right of redemption or postpone the date
of payment beyond seven days during any period when (a) trading on the New York
Stock Exchange is restricted, as determined by the Securities and Exchange
Commission, or such Exchange is closed for other than weekends and holidays; (b)
an emergency exists, as determined by the Commission, as a result of which
disposal by the Fund of securities owned by it is not reasonably practicable, or
it is not reasonably practicable for the Fund fairly to determine the value of
its net assets; or (c) the Commission by order so permits for the protection of
security holders of the Fund.

Shares of one portfolio may be exchanged for shares of another portfolio of the
Fund on the basis of the relative net assets value next computed after an
exchange order is received by the Fund.

The net asset value of the Fund's shares is determined on each day on which an
order for purchase or redemption of the Fund's shares is received and there is a
sufficient degree of trading in portfolio securities that the current net asset
value of its shares might be materially affected. Such determination is made as
of 4:00 p.m. Eastern time on each day the New York Stock Exchange is open for
unrestricted trading. The net asset value of each portfolio is computed by
dividing the value of the securities in that portfolio plus any cash or other
assets less all liabilities of the portfolio, by the number of shares
outstanding for that portfolio.

Securities which are held in a portfolio and listed on a securities exchange are
valued at the last sale price or, if there has been no sale that day, at the
last bid price reported as of 4 p.m. Eastern time. Over-the-counter securities
are valued at the last bid price as of 4 p.m. Eastern time.

The Board of Directors is ultimately responsible for determining the current net
asset values of each portfolio. The Board has authorized the Adviser and its
service providers to use the following sources to determine the current daily
prices of securities owned by the portfolios: Interactive Data Corporation (and
related "Fundrun" services), Reuters, Bloomberg and any brokers making a market
in a particular security.

Short-term debt securities in all portfolios other than the Money Market and
Omni Portfolios, with remaining maturities of 60 days or less, are valued at
amortized cost. The Fund has obtained an exemptive order from the Commission
permitting it to value all short-term debt securities in the Omni Portfolio at
amortized cost. The Fund relies on Rule 2a-7 under the Investment Company Act of
1940 to value the assets of the Money Market Portfolio on the basis of amortized
cost with a view toward stabilizing the net asset value at $l0 per share and
allowing dividend payments to reflect net interest income as earned.
Accordingly, the short-term debt assets of the Omni and Money Market Portfolios
are valued at their cost on the date of acquisition with a daily adjustment
being made to accrued income to reflect amortization of premium or accretion of
discount to the maturity date. All other assets of the Omni Portfolio and of
those portfolios other than the Money Market Portfolio, including restricted
debt securities and other investments for which market quotations are not
readily available, are valued at their fair value as determined in good faith by
the Board of Directors.

As a condition of the exemptive order, the Fund has agreed, with respect to
short-term debt securities in its Omni Portfolio, to maintain a dollar-weighted
average maturity of not more than l20 days and to not purchase any such debt
security having a maturity of more than one year. In relying on Rule 2a-7 with
respect to short-term debt securities in its Money Market Portfolio, the Fund
has agreed to maintain a dollar-weighted average portfolio maturity of not more
than 90 days and to not purchase any such debt security having a maturity of
more than 397 days. The dollar-weighted average maturity of short-term debt
securities is determined by dividing the sum of the dollar value of each such
security times the remaining days to maturity of such security by the sum of the
dollar value of all short-term debt securities. Should the disposition of a
short-term debt security result in a dollar-weighted average maturity of more
than the number of days allowed under the exemptive order or Rule 2a-7, as the
case may be, the Portfolio will invest its available cash so as to reduce such
average maturity to the required number of days or less as soon as reasonably
practicable. The Fund normally holds short-term debt securities to maturity and
realizes par therefor unless an earlier sale is required to meet redemption
requirements.

In addition, the Omni and Money Market Portfolios are required to limit their
short-term debt investments, including repurchase agreements, to those United
States dollar denominated instruments which the Board of




                                       30
<PAGE>   31


Directors determines present minimal credit risks and which are in the top two
rating categories of any nationally recognized statistical rating organizations
or, in the case of any instrument that is not rated, of comparable quality as
determined by the Board of Directors. Although the use of amortized cost
provides certainty in valuation, it may result in periods during which value so
determined is higher or lower than the price the Fund would receive if it
liquidated its securities.

The Fund's Board of Directors is obligated, as a particular responsibility
within the overall duty of care owed to Money Market Portfolio shareholders, to
establish procedures reasonably designed, taking into account current market
conditions and the investment objective of such Portfolio, to stabilize the
Portfolio's net asset value per share as computed for the purpose of
distribution, redemption and repurchase, at $l0 per share. The procedures
adopted by the Board of Directors include periodically reviewing, as it deems
appropriate and at such intervals as are reasonable in light of current market
conditions, the extent of deviation, if any, between the net asset value per
share based on available market quotations and such value based on the
Portfolio's $l0 amortized cost price. If such deviation exceeds 1/2 of 1
percent, or if there is any other deviation which the Board of Directors
believes would result in a material dilution to shareholders or purchasers, the
Board of Directors will promptly consider what action, if any, it should
initiate. Such action may include redemption in kind; selling portfolio
instruments prior to maturity to realize capital gains or losses, or to shorten
the average portfolio maturity; withholding dividends; splitting, combining or
otherwise recapitalizing outstanding shares; or using available market
quotations to determine net asset value per share. The Portfolio may reduce the
number of its outstanding shares by requiring shareholders to contribute to
capital proportionately the number of full and fractional shares as is necessary
to maintain the net asset value per share of $l0. ONLI and ONLAC, the sole
shareholders of the Money Market Portfolio, have agreed to this procedure and
contract owners who allocate purchase payments to the Money Market Portfolio
will be bound by such agreement.


                                   TAX STATUS

At December 3l, 1998 the Fund and each portfolio qualified as a regulated
investment company under Subchapter M of the Internal Revenue Code (the "Code").
Under such provisions, the Fund is not subject to federal income tax on such
part of its net ordinary income and net realized capital gains which it
distributes to shareholders. Each portfolio is treated as a separate entity for
federal income tax purposes, including determining whether it qualifies as a
regulated investment company and determining its net ordinary income (or loss)
and net realized capital gains (or losses). To qualify for treatment as a
regulated investment company, each portfolio must, among other things, derive in
each taxable year at least 90% of its gross income from dividends, interest and
gains from the sale or other disposition of securities. Each portfolio also
intends to comply with the diversification requirements or regulations under
Section 817(h) of the Code.

The foregoing is a general and abbreviated summary of the applicable provisions
of the Code and Treasury Regulations currently in effect. For the complete
provisions, reference should be made to the pertinent Code sections and the
Treasury Regulations promulgated thereunder. Since the only eligible
shareholders of the Fund are separate accounts of ONLI, ONLAC and other
insurance companies, no discussion is stated herein as to the federal income tax
consequences at the shareholder level.

The S&P 500 is a widely publicized index that tracks 500 companies traded on the
New York and American Stock Exchanges and in the over-the-counter market. It is
weighted by market value so that each company's stock influences the S&P 500 in
proportions to its relative market capitalization. Most of the stocks in the S&P
500 are issued by companies that are among the 500 largest in the United States
in terms of aggregate market value. However, for diversification purposes, some
stocks of smaller companies are included in the S&P 500.

                              THE YEAR 2000 ISSUE

The Fund, the Adviser and related entities believe they have succeeded in
remedying the "Year 2000" problem for all mission critical internal computer
systems and applications. Conversion testing and implementation for those
systems were completed by December 31, 1998. During the remainder of 1999,
peripheral personal computer systems will continue to be up-graded and tested
for Year 2000 implementation. While the Fund and the Adviser have been assured
by suppliers of financial services (including the custodians, the transfer agent
and the accounting agent) that their systems either are already compliant or
will be so in sufficient time, the Fund's internal auditors intend to
independently test those systems to verify their compliance. The Fund, the
Adviser and related entities are also developing contingency plans to be
prepared for the possibility that one or more service providers might not be
compliant. The failure of the Fund, the Adviser or one of their service
suppliers to achieve timely and



                                       32

complete compliance could materially impair the ability to conduct their
business, including the ability to accurately and timely value portfolio
securities and could have an adverse effect on the portfolios.

                                    APPENDIX

DEBT SECURITY RATINGS

The Commission has designated six nationally recognized statistical rating
organizations: Duff and Phelps, Inc. ("D&P"), Fitch Investors Service, Inc.
("Fitch"), Moody's Investors Service, Inc. (Moody's"), Standard & Poor's Corp.
("S&P"), and, with respect to bank-supported debt and debt issued by banks,
broker-dealers and their affiliates, IBCA Inc. and its British affiliate, IBCA
Limited ("IBCA") and Thompson Bankwatch, Inc. ("TBW"). The Adviser may use the
ratings of all six such rating organizations as factors to consider in
determining the quality of debt securities, although it will generally only
follow D&P, Fitch, Moody's and S&P. IBCA and TBW will only be consulted if fewer
than two of the other four rating organizations have given their top rating to a
security. Only the ratings of Moody's, S&P and Fitch will be considered in
determining the eligibility of bonds for acquisition by the Fund.

MOODY'S INVESTORS SERVICE, INC. ("MOODY'S")

Commercial Paper:
- -----------------

Moody's short-term debt ratings are opinions of the ability of issuers to
punctually repay senior debt obligations having an original maturity not
exceeding one year.

P-1   The Prime-1 (P-1) rating is the highest commercial paper rating assigned
      by Moody's. Issuers (or supporting institutions) rated P-1 have a superior
      ability for repayment of senior short-term debt obligations. P-1 repayment
      ability will often be evidenced by many of the following characteristics:
      leading market positions in well-established industries, high rates of
      return on funds employed, conservative capitalization structure with
      moderate reliance on debt and ample asset protection, broad margins in
      earnings coverage of fixed financial charges and high internal cash
      generation, and well-established access to a range of financial markets
      and assured sources of alternate liquidity.

P-2   Issuers (or supporting institutions) rated Prime-2 (P-2) have a strong
      ability for repayment of senior short-term obligations. This will normally
      be evidenced by many of the characteristics cited above for P-1, but to a
      lesser degree. Earnings trends and coverage ratios, while sound, may be
      more subject to variation. Capitalization characteristics, while still
      appropriate, may be more affected by external conditions. Ample alternate
      liquidity is maintained.

Bonds:
- ------

Aaa   Bonds which are rated Aaa by Moody's are judged to be of the best quality.
      They carry the smallest degree of investment risk and are generally
      referred to as "gilt edge." Interest payments are protected by a large or
      by an exceptionally stable margin and principal is secure. While the
      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 as Aa by Moody's are judged to be of high quality by
      all standards. Together with the Aaa group, they comprise what are
      generally known as high grade bonds. They are rated lower than the best
      bonds because margins of protection may not be as large as in Aaa
      securities or fluctuation of protective elements may be of greater
      amplitude or there may be other elements present which make the long-term
      risks appear somewhat larger than in Aaa securities.

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

Baa   Bonds which are rated Baa by Moody's are considered as medium grade
      obligations, that is, 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



                                       34
<PAGE>   35


      over any great length of time. Such bonds lack outstanding investment
      characteristics and in fact have speculative characteristics as well.

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

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.

Moody's applies numerical modifiers, 1, 2, and 3, in each generic rating
classification from Aa through B in its corporate bond rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range ranking; and the modifier
3 indicates that the issue ranks in the lower end of its generic rating
category.

STANDARD & POOR'S CORP. ("S & P")

Commercial Paper:
- -----------------

An S&P commercial paper rating is a current assessment of the likelihood of
timely payment of debt having an original maturity of no more than one year.

A-1   This is S&P's highest category and it indicates that the degree of safety
      regarding timely payment is strong. Those issues determined to possess
      extremely strong safety characteristics are designated A-1+.

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 as A-1.

Bonds:
- ------

AAA   Bonds rated AAA by S&P are the highest grade obligations. They possess the
      ultimate degree of protection as to principal and interest. Market prices
      move with interest rates, and hence provide maximum safety on all counts.

AA    Bonds rated AA by S&P also qualify as high grade obligations, and in the
      majority of instances differ from AAA issues only in small degree. Here,
      too, prices move with the long-term money market.

A     Bonds rated A by S&P are regarded as upper medium grade. They have
      considerable investment strength but are not entirely free from the
      adverse effects of changes in economic and trade conditions. Interest and
      principal are regarded as safe. They predominantly reflect money rates in
      their market behavior, but to some extent, also economic conditions.

BBB   The BBB or medium grade category is the borderline between definitely
      sound obligations and those where the speculative element begins to
      predominate. These bonds have adequate asset coverage and normally are
      protected by satisfactory earnings. Their susceptibility to changing
      conditions, particularly to depressions, necessitates constant watching.
      Marketwise, the bonds are more responsive to business


                                       35
<PAGE>   36


      and trade conditions than to interest rates. This is the lowest group
      which qualifies for commercial bank investments.

Debt rated `BB.' `B,' `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 such debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties of major exposures to adverse
markets.

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     The rating `CC' typically is applied to debt subordinated to senior debt
       that is assigned an actual or implied `CCC' rating.

C      The rating `C' typically is applied to debt subordinated to senior debt
       that is assigned an actual or implied `CCC-' 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 S&P believes
       that such payments will be made during such grace period. The `D' rating
       will also be used upon the filing of a bankruptcy petition if debt
       service payments are jeopardized.

The ratings from `AA' to `CCC' may be modified by the addition of a plus (+) or
minus (-) to show relative standing within the major rating categories.

DUFF & PHELPS, INC. ("D & P")

Commercial Paper:
- -----------------

D&P's short-term ratings have incorporated gradations of "1+" and "1-" in
recognition of quality differences within the first tier.

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.



                                       36
<PAGE>   37


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.

FITCH INVESTORS SERVICE, INC. ("FITCH")

Commercial Paper
- ----------------

Fitch's short-term ratings apply to debt obligations that are payable on demand
or have original maturities of up to three years, including commercial paper,
certificates of deposit, medium-term notes, and municipal and investment notes.
Fitch's short-term ratings emphasize 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 carrying this rating have a satisfactory
        degree of assurance for timely payment, but the margin of safety is not
        as great as the F-1+ and F-1 categories.

Bonds
- -----

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 these 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 interst and repay principal is
        considered to be adequate. Adverse changes in economic conditions and
        circumstances, however, are more likely to have adverse impact on these
        bonds, and therefore impair timely payment. The likelihood that the
        rating of these bonds will fall below investment grade is higher than
        for bonds with higher ratings.

BB      Bonds are considered to be 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 issues.

CCC     Bonds have certain identifiable characteristics that, 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.



                                       37
<PAGE>   38


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

DDD,    DD and D Bonds in default on interest and/or principal payments. Such
        bonds are extremely speculative and should be valued on the basis of
        their ultimate recovery value in liquidation or reorganization of the
        obligor. `DDD' represents the highest potential for recovery on these
        bonds, and `D' represents the lowest potential for recovery.

Note: Fitch ratings (other than `AAA.' `DDD,' `DD,' or `D' categories) may be
modified by the addition of a plus (+) or minus (-) sign to show relative
position of a credit within the rating category.

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The Equity Portfolio return was 5.72% for 1998. Although the large
capitalization stock portion of the portfolio provided returns consistent with
the major indices, the portfolio's exposure to small and mid-capitalization
stocks pulled the overall return down considerably. We were invested in these
areas because the valuations relative to the large capitalization stocks were
very attractive. Unfortunately, these areas corrected far more than the large
capitalization stocks and the major indices during the stock market downturn.
Even though the portfolio's returns were consistent with the major indices from
the October 8th market bottom through the end of the year, the performance
during the mid year market correction caused the portfolio to lag for the 1998
year.

We expect the stock market to continue in a volatile manner. We expect the U.S.
economy and economic activity around the world to slow somewhat during 1999. We
feel that growth will be rewarded and thus we will attempt to increase the
growth aspects of the portfolio.

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The bond portfolio returned 5.22% in 1998 versus 8.44% for the Lehman Brothers
Government/Corporate Intermediate Bond Index. With a lesser percentage of U.S.
Treasury bonds in the portfolio versus the index, the performance of our fund
suffered during a year in which corporate spreads of all types widened
significantly. In particular, our fund has a large number of "Baa-rated"
corporates which experienced poor performance because of liquidity and credit
concerns which overtook the bond market in the last half of the year.

So far in 1999 through January, corporate bonds in the "Baa" category are
performing better than U.S. Treasury bonds because credit spreads are tightening
and we are more optimistic on the relative performance of the fund this year.

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The Omni portfolio return was 4.53% for 1998. Although the large capitalization
stock portion of the portfolio provided returns consistent with the major
indices, the portfolio's exposure to small and mid-capitalization stocks pulled
the overall return down. We were invested in these areas because the valuations
relative to the large capitalization stocks were very attractive. Unfortunately,
these areas corrected far more than the large capitalization stocks and the
major indices during the stock market downturn. The fixed income portion of the
portfolio consists primarily of investment grade corporate bonds. This portion
of the fixed income market did not perform as well as the Government Security
portion of the market. This was caused by investors' concern with worldwide
economic issues and political uncertainties; the result was a flight to safety.

We expect the stock market to continue in a volatile manner. We expect the U.S.
economy and economic activity around the world to slow somewhat during 1999. We
will focus our efforts on investing more in growth issues and companies growing
their dividends at least two to three times GDP. We expect the corporate bond
sector of the fixed income market to perform more favorably. Asset allocations
will remain near current levels.

vary. All returns reflect reinvested dividends. The portfolio's holdings may
differ significantly from the securities in the index. The index is unmanaged
and therefore does not reflect the cost of portfolio management or trading.

 OBJECTIVE

The International Portfolio seeks long-term capital growth by investing
primarily in securities of foreign Companies.

 PERFORMANCE AS OF DECEMBER 31, 1998

<TABLE>

AVERAGE ANNUAL TOTAL RETURNS:
One-year                                      3.88%
Three-year                                    6.69%
Five-year                                     8.03%

</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

Despite continued concerns over the impact of the Asian crisis on global
economies, European indices surged ahead until mid-July. At that time, Russia
devalued its currency and defaulted on its Ruble denominated obligations, the
outlook in Latin American markets worsened as Brazil became an area of increased
worries, and a large U.S. hedge fund collapsed in September. Within a few weeks,
mature markets lost 20 to 30% while emerging markets were once again decimated.

In Asia, Japanese equities weakened farther as additional evidence of
deteriorating economic conditions and slow progress made toward the
implementation of long-awaited banking reforms. Global market developments
placed other Asian markets under pressure. Meanwhile, in Latin America, the
possibility of additional currency devaluations continued to weigh on local
stock markets.

In such an environment, small capitalization stocks fared even worse than large
capitalization stocks and suffered steep losses. Smaller stocks account for the
large majority of the Fund's holdings: while world markets stabilized later in
the year. Blue chips gained and reversed most of their losses, many of the small
issues did not recover. The performance of the Funds was therefore negatively
impacted by those developments.

The risk associated with investing on a worldwide basis includes differences in
regulation of financial data and reporting and currency exchanges as well as
economic and political systems which may be different from those in the United
States. The prices of small company stocks are generally more volatile than the
prices of large company stocks.

may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The first six months of 1998 was a period of surging stock market gains -- not
the kind of environment in which this conservative portfolio outperforms. While
the portfolio participated in the market's advance, its asset allocation and
value approach to security selection meant that it had much less exposure than
many large-cap stock funds to the classic types of stocks that were leading the
market, primarily blue chip growth companies. When the bull market turned
bearish in the summer of 1998, the portfolio's defensive stance served
shareholders well. During the quarter ended September 30, for example, the
portfolio held up significantly better than the broad market. When the S&P 500
fell almost 15% in August, the portfolio was down less than 5%.

As of this writing the stock market has roared back, recovering lost ground in
record time. As a result, stock valuations seem high to us, just as they
appeared last summer before the steep sell-off. The difference is that all signs
now seem to point to a definite slowing in the economy next year; demand for US
production is dropping, and corporate pricing power is under pressure around the
world, hurting profits. On the positive side, low interest rates could provide
some cushion for consumer spending. Nevertheless, the stock market has
traditionally followed profit trends, which suggest another correction could be
in the offing. If this occurs, the Capital Appreciation portfolio should weather
the storm better than the overall market. Our investment approach will remain
the same regardless of what unfolds. We seek to provide attractive total returns
over time for investors who prefer not to be exposed to the full blast of stock
market volatility.

may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

While 1998 has been a volatile year with many cross-currents, there remains a
generally positive environment for most investors: low inflation, low
unemployment, and steady but moderate economic growth.

International financial crises, particularly in Asia, stalled many economies
around the world and affected corporate growth globally. This backdrop favored
large companies for most of the year, but from the bottom of the October
correction, small-cap performance has improved significantly. From October 8
through December 4, the benchmark Russell 2000 outperformed both the S&P 500 and
the DJIA by more than 6% and 9%, respectively.

The Ohio National Small-Cap Fund has benefited from this upswing in
small-company stocks. It has dramatically outperformed the Russell 2000, gaining
more than 46.0% from its low, versus 30% for the index since October. Using our
disciplined, bottom-up process, we continue to find companies with strong
fundamentals and innovative products. The valuation differential, which favors
small companies, is encouraging, and we are optimistic that as the economic
environment remains subdued, the superior growth characteristics of small-caps
stocks will be realized.

We enter 1999 with a generally positive economic setting. It is expected that
interest rates around the world will continue to fall, with expectations that
inflation will remain low. Economic growth in the United States continues at a
slow, but positive pace, and Europe should benefit from the cross-border
business brought by the new euro. Although the worst of the crisis in Asia may
be behind us, we believe the weakness in Asia will be measured in years, not
months.

These factors should provide a favorable environment overall for financial
assets, particularly stocks of smaller companies. We believe the growth in
communications and global commerce should continue to provide opportunities for
many companies. We are excited about the opportunities being created in the
small-cap market, and we are confident that on a long-term basis, small
companies will provide superior returns.

GLOBAL CONTRARIAN PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Global Contrarian Portfolio seeks to provide long-term growth of capital by
investing in foreign and domestic securities that are undervalued or presently
out of favor with other investors but have positive prospects for eventual
appreciation.

 PERFORMANCE AS OF DECEMBER 31, 1998

AVERAGE ANNUAL TOTAL RETURNS:

<TABLE>
<S>                                         <C>
One-year                                     3.53%
Three-year                                   9.02%
Since inception (3/31/95)                    9.64%
</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The Global Contrarian Portfolio contains mostly small and obscure stocks which
we believe are neglected. They also have exposure to commodity and/or "hard
asset" related stocks in U.S. as well as foreign markets. Finally, they hold
emerging market debt instruments, both corporate and sovereign. Stock markets
fell sharply around the world during the third quarter and then rebounded
sharply during the fourth quarter. Small stocks and commodity related stocks
continued to fare poorly, especially compared to the big growth stocks.

The portfolio has been reducing its exposure to commodities-related securities
over the last eighteen months as weaker global economic growth is anticipated in
the medium-term following the Asian crisis. Exposure to certain Latin American
debt instruments has also been reduced. Simultaneously, the portfolio recently
started buying selected stocks and bonds that appear depresses significantly in
a few Asian countries, as well as in Australia, the U.S., and Europe.

The risk associated with investing on a worldwide basis includes differences in
regulation of financial data and reporting and currency exchanges as well as
economic and political systems which may be different from those in the United
States. The prices of small company stocks are generally more volatile than the
prices of large company stocks.

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The portfolio has outperformed the small-cap Russell 2000 for the year, but
lagged the Russell Mid-Cap Growth and S&P 500 Indexes in spite of appropriate
strategic moves. Performance was especially hurt by our heavy positions in
small-cap stocks, which were devastated by the flight to quality, even though
the majority of our investments have hit their profit targets. Stock selection
emphasized dependable growth companies, whose profits should hold up even in the
face of an economic downturn.

We began positioning the portfolio's investments for a deteriorating economic
climate and difficult stock market during the third quarter. We decreased
exposure to cyclicals and retail stocks, and increased cash to reinforce the
portfolio's defensive posture. Heavy cash positions hurt relative performance
after the market began to rebound in October. Financial Stocks were also trimmed
due to their lower earnings trend.

Most macroeconomic indicators point to a decline in U.S. economic activity and
corporate profits in the next few quarters. The Fed appears willing to counter
the slowdown with the use of monetary stimulus. Although we remain cautious,
valuations for all but the few largest stocks have become extremely attractive.
We will continue to exploit the best growth opportunities in companies with
capable management and dependable earnings.

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

We can sum up the second half of 1998 in one word -- volatile. The large-cap
indexes hit their summer peak in mid-July, then lost ground through the rest of
July and hit a low for the third quarter on the last day of August. In
September, stocks staged a healthy rebound, but did not recover to their levels
at the end of the second quarter. The market declined significantly in early
October, only to rebound even more dramatically through the end of the year.

Throughout the year, small-cap and mid-cap stocks did not participate fully when
the market was going up, but they certainly participated when the market went
down. We entered the fourth quarter with the S&P 500 Index up 6% and the Russell
2000 Index down 16% for the year -- a remarkable divergence of returns.

We think that smaller stocks will participate more fully in any market increases
this year for several reasons. Earnings growth has slowed drastically for the
larger companies that make up the S&P 500 Index. At the same time earnings
growth in the small and mid-cap universe remains strong and valuations are at or
near all time lows. Finally, while emerging market economies continue to be a
concern, we believe any improvement in these countries should make investors
more willing to hold less liquid stocks.

GROWTH & INCOME PORTFOLIO

OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Growth & Income Portfolio's investment objective is long-term total return.

 PERFORMANCE AS OF DECEMBER 31, 1998

TOTAL RETURN:

<TABLE>
<S>                                          <C>
One-year                                      7.09%
Since inception (1/3/97)                     21.05%
</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

Fueled by a strong, snap back rally in the market, the Ohio National Growth &
Income Portfolio rose 16.5% in the fourth quarter. The strong rebound helped to
mitigate the severe underperformance investors in small and mid-cap stocks
endured throughout most of the second and third quarter in 1998.

Having endured a strong market decline in the spring and summer, we positioned
the portfolio in a defensive posture entering the fourth quarter. We expanded
our weighting to convertible, preferred, and utility shares. That conservative
strategy hindered our fourth quarter results, as many stocks rallied strongly
from their summer lows.

Looking forward, we maintain some optimism that the small and mid-cap stocks may
catch up to the large cap stocks in 1999 after four years of general
underperformance. The deflationary forces of excess global capacity coupled with
slowing demand from most energy markets have already had a negative effect on
the profits of some large-cap multinational companies.

S&P 500 INDEX PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The S&P 500 Index Portfolio seeks total return approximating that of the S&P 500
Index, including reinvestment of dividends, at a risk level consistent with that
of the S&P 500 Index.

 PERFORMANCE AS OF DECEMBER 31, 1998

<TABLE>
<S>                                         <C>
TOTAL RETURN:
One-year                                    30.00%
Since inception (1/3/97)                    31.03%
</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

1998 turned out to be a very volatile, but yet another good year for the S&P 500
Index and for your S&P 500 Index Fund. After the 1st seven months of 1998, we
had seen two months of negative returns, but good overall gains of nearly 16.50%
for the S&P Index. In August, however, with negative sentiment leading the way,
the market dropped 14.6%, wiping out most of the gains for the year. Next we had
strong months in September through December, bringing the index all the way back
for a total return of 28.58% for all of 1998, including dividends reinvested
back into the index.

Your Ohio National Index Fund mirrored these volatile ups and downs, leading all
index funds in return most of the year. It finished the year as the number one
index fund in the country, with a total return after expenses of 30.00%, or
1.42% higher than the actual index. The next highest return for "Insurance
Products Underlying Funds -- S&P 500 Index Funds," was 28.72% for the year. The
highest return for S&P 500 Index Funds -- non-insurance product related -- was
29.34% for the year. Returns are reported by Lipper's analytical review
services, ranking over 130 S&P 500 index funds.

1999 is a promising year. Economic growth fundamentals are good, with wage
inflation pressures lessening, low interest rates and forecast low inflation. We
expect GDP growth to remain strong, though lower than the 3.9% rate for 1998.
Year 2000 hiccups will probably occur during 1999, plus some damage from weak
Asian and South American economies. As the economy slows from its 3.9% growth
rate, expect questions of stock market overvaluation to recur. Ultimately, it
will be another volatile year in the stock market, but we expect to be
discussing stock market gains with you 12 months from now.

securities of companies that, in the Adviser's opinion, conduct their business
in a way that enhances society's quality of life. The portfolio's social concern
criteria will necessarily limit the universe of securities that may be selected
for this portfolio. However, the Adviser believes the portfolio's objective of
long-term capital growth can be achieved despite this limitation.

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

As expected, 1998 has turned out to be a volatile period for equity markets. The
magnitude of the swings, however, has been surprising. The general market peaked
in late April. In response to economic turmoil worldwide, investors sought out
highly liquid, blue chip issues and Treasury securities in a flight to quality.
As a result, small capitalization issues suffered the eighth 30%+ decline over
the past 72 years. Although markets have rebounded since early October, many
securities have yet to fully recover. As of year end, the average NASDAQ issue
remains 38% off its 52 week high and the average S&P 500 issue remains 19% off
its 52 week high.

The Social Awareness Portfolio has been hurt by the market turmoil. The fund
normally invests in a range of large, medium and small capitalization issues.
Cash positions were slightly over 10% at the end of April. The cash was invested
gradually over the next several months, only to feel the brunt of the selloff in
August and early October. Issues that normally sell between 15 to 17 times
earnings, or in line with estimated future growth rates, sold for 10 times
earnings at the end of the third quarter. For the year, positive results from
technology and transportation issues were offset by weakness in other areas,
most notably capital goods and energy holdings.

In conclusion, markets in 1999 will still experience volatility. Economic
conditions world wide are uncertain, but look to be mending. Expectations for
corporate profitability could also be too high. We are hopeful smaller and
medium capitalization issues will recover to reasonable valuation levels.
Clearly, short term results for the Social Awareness Portfolio have been
unacceptable. However, prospects remain solid and we are taking some measures
which would mitigate some of the fluctuations experienced during the past year.

STRATEGIC INCOME PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Strategic Income Portfolio seeks to generate high current income by
investing at least 80% of its assets in income-producing securities, including
at least 40% of assets in a core group of U.S. government and corporate
fixed-income securities, and the remainder in other income-producing securities.

 PERFORMANCE AS OF DECEMBER 31, 1998

TOTAL RETURN:

<TABLE>
<S>                                         <C>
One-year                                    (1.42%)
Since inception (1/3/97)                     3.55%
</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The Strategic Income Fund has always been an interesting product. Its concept is
unique and our approach conservative in pursuing a high level of income. Last
year was successful in terms of maintaining a high-income stream and low NAV
volatility. Unfortunately, market dislocations resulted in a negative total
return in a calendar year. What happened and how are we reacting? Simply stated,
international turmoil resulted in a "crisis of confidence" that drove investors
away from risky assets into the safety of U.S. Treasury securities. Yields
declined dramatically for Treasury notes, but only slightly for corporates and
mbs's. At the peak of despair, corporate bond valuations were priced as if a
recession was raging and defaults imminent.

Our fixed income outlook for 1999 includes the following key points: Positive
economic growth (2% to 3% for the year) and mild inflation pressures (2%); Bond
yields remaining within a 4.5% to 5.5% range; Federal Reserve to lower key
short-term rates 25-75 basis points; and improving market liquidity. We also
believe REIT's offer tremendous value as evidenced by P/E's close to 10X and
revenue growth for most operations are expected to top 8% in 1999.

STELLAR PORTFOLIO

OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Stellar Portfolio seeks to maximize total return by investing approximately
15% to 25% of its assets in each of the following categories: domestic equities,
domestic bonds, foreign securities, real estate securities, and precious metal
and/or money market securities.

 PERFORMANCE AS OF DECEMBER 31, 1998

TOTAL RETURN:

<TABLE>
<S>                                         <C>
One-year                                     2.92%
Since inception (1/3/97)                     6.28%
</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The prevailing market conditions were ideal for investors in the Stellar
portfolio. The Fund insulated shareholders from much of the volatility in equity
prices, while benefiting in performance terms from the rally in bond prices. The
REIT portfolio suffered the most severe damage during the second and third
quarters, due principally to a change in the tax code and slowing growth for the
group. The domestic equity portfolio was the most volatile and rewarding. The
key to success in the U.S. was the decision to focus on large capitalization
growth companies. This subset of the market moved to higher valuation levels
throughout the year, as investors became more and more concerned about a decline
in revenue growth.

Investor expectations for 1999 are still out of line with reality. As we have
seen thus far in 1998, the market reacts violently to disappointments and tends
to overreact in both the positive and negative. We believe that the market must
adjust expectations for earnings growth in 1999 to reflect the slowing
manufacturing activity and the rising costs in the services sector, but still
positive year over year growth.

RELATIVE VALUE PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Relative Value Portfolio seeks the highest total return as is consistent
with reasonable risk by investing in stocks deemed to represent characteristics
with low volatility, above-average yields and are undervalued relative to the
stocks comprising the S&P Composite Stock Index.

 PERFORMANCE AS OF DECEMBER 31, 1998

<TABLE>
<S>                                         <C>
TOTAL RETURN:
One-year                                    20.72%
Since inception (1/3/97)                    24.53%
</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

During the past twelve months, the equity market saw significant volatility due
to concerns over Asia, corporate earnings, and the turmoil in the White House.
How did the portfolio perform versus the average growth and income fund? By
adhering to the tenets of the valuation process employed by the fund, the
securities selected are typically those which exhibit a higher degree of
operating and financial stability. During volatile periods in the market, stocks
possessing these attributes command a premium in valuation as a "flight to
quality" intensifies demand for these stocks. For the twelve months ending
November 30, 1998 the Relative Value Fund generated a total rate in excess of
16% on a net asset value basis. This compares to an 11.61% return for the
average growth and income fund as reported by Lipper Analytical Services, Inc.

As we look to 1999, we forecast a slow growth economic environment where
inflation continues to remain benign and corporate earnings growth slows to
single digit increases. Technology and healthcare will continue to provide
market leadership in the fund and we will continue to pursue opportunities in
the consumer cyclicals, communication, financial services, and energy companies.

differ significantly from the securities in the index. The index is unmanaged

OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Blue Chip Portfolio seeks growth of capital and income by investing in
securities of high quality companies.

TOTAL RETURN:
Since inception (5/1/98)                     2.34%
</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

1998 was an extremely difficult year for active value managers. The S&P 500's
28.7% return was dominated by a handful of ultra-large growth oriented
Technology, Pharmaceutical, and Telephone companies. The return for the average
stock in the S&P 500, as measured by the equal-weighted S&P 500, was only 12.8%.
This nearly 16% disparity between the average stock and the market itself is
something the market has not experienced in the last 25 years. In this difficult
environment the portfolio, from its inception on May 1, 1998, returned 2.34%.
This return was in line with our value oriented benchmarks: The average Lipper
Growth & Income fund returned 2.59% and the S&P Value Index returned 1.41%. We
are obviously not pleased with our relative performance versus the S&P 500, but
given our investment style and market conditions, the returns are not
unreasonable. It is worth noting that historically, after periods of extremely
narrow market leadership dominated by a handful of growth stocks, active value
management can provide superior returns.

As we enter 1999, the markets are faced with numerous challenges. At a P/E ratio
nearing 30 times, and price-to-book ration north of 8 times and a dividend yield
of 1.3%, the S&P 500 is in uncharted valuation territory for this point in any
business cycle. In this type of environment, we believe that our value
disciplines -- identifying leading companies which are temporarily out of favor
and appear inexpensive relative to their history relative to the market as well
as to their expected growth -- will provide a more reasonable ride as
rationality works its way back into the market.

EQUITY INCOME PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Equity Income Portfolio seeks above-average income and capital appreciation
by investing primarily in income-producing equity securities

 PERFORMANCE AS OF DECEMBER 31, 1998

<TABLE>
<S>                                         <C>
TOTAL RETURN:
Since inception (5/1/98)                     5.92%
</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The S&P 500 has just completed its fourth consecutive year of 20%+ gains. After
falling nearly 20% from its July 17 market peak, the S&P began a dramatic
recovery in early October, to finish the year with a total return of 28.58%.
While this is an extremely impressive showing, it was accompanied by volatility
which had been absent for a number of years. Additionally, the advance was
concentrated in a handful of companies. Specifically, 20 stocks accounted for
59% of the market's rise, while 100 stocks accounted for 85% of its gain.
Unfortunately, the median gain for a stock in the S&P 500 was only 2% with over
70% of the stocks lagging the index return. Since inception on May 1, 1998
through December 31, 1998, the Blue Chip portfolio's total return of 5.92% was
ahead of the 2.00% return of the average equity income fund.

The economic outlook for 1999 appears weak, particularly on a global basis. Only
limited signs point to a bottoming of Asians economies, while Latin American
economies continue to decelerate. The U.S. economic picture is mixed. Industrial
production is weakening even as consumer spending and confidence remains strong,
aided by declines in energy prices and interest rates. In fact, inflation is
close to zero and deflation has become a real fear.

differ significantly from the securities in the index. The index is unmanaged

HIGH INCOME PORTFOLIO

OHIO NATIONAL FUND, INC.

 OBJECTIVE

The High Income Bond Portfolio seeks high current income by investing primarily
in lower rated corporate debt obligations.

 PERFORMANCE AS OF DECEMBER 31, 1998

TOTAL RETURNS:

</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The 12 months ending December 31, 1998 was marked by volatility and generally
disappointing returns from a high yield bond perspective. There were several
reasons for the volatility and disappointing returns including problems in the
international arena, a mid summer stock market swoon, hedge fund problems,
falling commodity prices, and a growing consensus in the latter part of 1998
pointing to a slowing of the domestic economy in 1999. These factors caused high
yield bonds to underperform high quality bonds. For example, the Lehman Brothers
High Yield Bond Index returned 1.87% substantially underperforming the Lehman
Brothers Aggregate Bond Index, a measure of high quality bond performance, which
returned 8.70%

As we look out into 1999, many contradicting factors are present. On the
negative side, concerns continue regarding our international trading partners
such as Japan and Latin America on the domestic economy, falling commodity
prices, and the uncertainty of Y2K and the volatility of the stock market. On
the plus side, the consensus economic forecast sees the domestic economy
continuing its remarkable growth for another year although at a slower pace,
inflation is almost non-existent, and most importantly, the yield spread between
high yield bonds and Treasury securities remains very wide especially in light
of the amazing resilience of the domestic economy. Overall, wide spreads and
positive economic growth should make 1999 a good year for high yield securities

SMALL CAP GROWTH PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Small Cap Growth Portfolio seeks capital appreciation by investing primarily
in common stocks of emerging growth companies.

 PERFORMANCE AS OF DECEMBER 31, 1998

<TABLE>
<S>                                          <C>
TOTAL RETURN:
Since inception (5/1/98)                     4.62%
</TABLE>

Returns represent past performance, which is no guarantee of future results.
Investment return and principal value will vary so that shares, when redeemed,
may be worth more or less than their original cost. Actual results for variable
annuity and variable universal life contracts will be lower due to contract
charges. Consult your contract for applicable charges for mortality and
expenses.

 COMMENTS

The small-cap sector was volatile, depressing, inspiring, and when all was done,
reasonably flat in performance for the year. Fortunately, we managed to provide
significantly better returns.

The portfolio rose 36.33% in the fourth quarter 1998. This compares to the
benchmark Russell 2000 Growth that rallied up 23.64% in the fourth quarter to
close the year with a modest 1.23% return. On the strength of a strong fourth
quarter, we produced a since inception return of 4.62% versus a decline of
10.07% in the benchmark Russell 2000 Growth.

The small-cap market provided investors a great challenge last year. Our
diligent research effort paid off significantly, enabling us to understand,
analyze, and finally purchase a broad number of truly exciting emerging growth
companies and navigate the volatility that characterized the year. We go into
1999 cautiously optimistic about the small-cap investment environment.

Hypothetical illustration based on past performance. Future performance will
vary. All returns reflect reinvested dividends. The portfolio's holdings may
differ significantly from the securities in the index. The index is unmanaged
and therefore does not reflect the cost of portfolio management or trading.

NOTES TO FINANCIAL STATEMENTS

(1) BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

    Ohio National Fund, Inc. (Fund) is registered under the Investment Company
    Act of 1940 as amended (the "1940 Act"), as a diversified, open-end
    management investment company. The Fund is a series investment company which
    consists of twenty separate investment portfolios that seek the following
    investment objectives:

    o Equity Portfolio -- long-term growth of capital by investing principally
      in common stocks or other equity securities. Current income is a secondary
      objective.

    o Money Market Portfolio -- maximum current income consistent with
      preservation of capital and liquidity by investing in high quality money
      market instruments.

    o Bond Portfolio -- high level of return consistent with preservation of
      capital by investing primarily in high quality intermediate and long-term
      debt securities.

    o Omni Portfolio -- high level of long-term total return consistent with
      preservation of capital by investing in stocks, bonds, and money market
      instruments.

    o International Portfolio -- long-term capital growth by investing primarily
      in common stocks of foreign companies.

    o Capital Appreciation Portfolio -- maximum capital growth by investing
      primarily in common stocks that are (1) considered to be undervalued or
      temporarily out of favor with investors, or (2) expected to increase in
      price over the short term.

    o Small Cap Portfolio -- maximum capital growth by investing primarily in
      common stocks of small- and medium-sized companies.

    o Global Contrarian Portfolio -- long-term growth of capital by investing in
      foreign and domestic securities believed to be undervalued or presently
      out of favor.

    o Aggressive Growth Portfolio -- capital growth.

    o Core Growth Portfolio -- long-term capital appreciation.

    o Growth & Income Portfolio -- long-term total return by investing in equity
      and debt securities focusing on small- and mid-cap companies that offer
      potential for capital appreciation, current income, or both.

    o S&P 500 Index Portfolio -- total return that approximates that of the
      Standard & Poor's 500 Index ("S&P 500") by investing in common stocks and
      in stock index futures contracts hedged by U.S. Government obligations,
      investment grade corporate bonds and cash equivalents.

    o Social Awareness Portfolio -- long-term capital growth by investing
      primarily in common stocks and other equity securities of companies that,
      in the Advisor's opinion, conduct their business in a way that enhances
      society's quality of life.

    o Strategic Income Portfolio -- high current income by investing at least
      40% of its assets in a core group of U.S. government and corporate fixed
      income securities and the remainder in other income producing securities.

    o Stellar Portfolio -- maximum total return by investing in domestic and
      foreign securities (equity and fixed income), real estate, precious metal
      securities, and money market securities.

    o Relative Value Portfolio -- maximum total return consistent with
      reasonable risk by investing primarily in equity securities.

    The following portfolios commenced operations on May 1, 1998:

    o Blue Chip Portfolio -- growth of capital and income by concentrating
      investment decisions in securities of high quality companies.

    o Equity Income Portfolio -- above average income and capital appreciation
      by investing primarily in high quality income producing equity securities
      including common stock, preferred stock, REIT's, and securities
      convertible into common stock.

OHIO NATIONAL FUND, INC.                                       December 31, 1998
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

    o High Income Bond Portfolio -- seek high current income by investing
      primarily in lower rated corporate debt obligations commonly referred to
      as "junk bonds". The portfolio's investments are generally rated Baa or
      lower by Moody's, or BBB or lower by S&P or Fitch.

    o Small Cap Growth -- capital appreciation by investing in and actively
      managing equity securities in emerging growth companies.

    The following is a summary of significant accounting policies:

    Investments in the Money Market Portfolio are valued at amortized cost in
    accordance with Rule 2a-7, which approximates market value. All net
    investment income of the Money Market Portfolio is declared and paid daily
    as a dividend to shareholders immediately before the computation of the net
    asset value of Money Market Portfolio shares. Dividends are automatically
    reinvested in additional Money Market Portfolio shares at the net asset
    value immediately following such computation. Distributions arising from net
    investment income from the remaining portfolios are declared and paid to
    shareholders quarterly and are recorded on the ex-dividend date.
    Distributions arising from accumulated net realized capital gains are
    recorded on the ex-dividend date and are distributed to shareholders at
    least once a year.

    For all but the Money Market Portfolio, securities which are traded on U.S.
    and foreign stock exchanges or in the over-the-counter markets are valued at
    the last sale price or, if there has been no sale that day, at the last bid
    reported as of 4:00 p.m. Eastern time on each day the New York Stock
    Exchange is open for unrestricted trading. Over-the-counter securities are
    valued at the last bid price as of the close of trading on the Exchange.
    Short-term investments (investments with remaining maturities of 60 days or
    less) are valued at amortized cost and fixed income securities are valued by
    using market quotations, or independent pricing services which use prices
    provided by market makers or estimates of market value obtained from yield
    data relating to instruments or securities with similar characteristics. All
    investments and cash quoted in foreign currencies are valued daily in U.S.
    dollars on the basis of the foreign currency exchange rates prevailing at
    the time of such valuation.

    Foreign currency exchange rates are generally determined prior to 4:00 p.m.
    Eastern time. Occasionally, events affecting the value of foreign
    investments and such exchange rates occur between the time at which they are
    determined and the time of valuation, which in the case of the
    International, Small Cap, Global Contrarian, Aggressive Growth, Stellar,
    Blue Chip, and Small Cap Growth Portfolios would not be reflected in the
    computation of the portfolios' net asset value. If events materially
    affecting the value of such securities or currency exchange rates occurred
    during such time period, the securities are valued at their fair value as
    determined in good faith by or under the direction of the Fund's Board of
    Directors.

    In connection with purchases and sales of securities denominated in foreign
    currencies, the Fund may enter into forward foreign currency exchange
    contracts (forward contracts). A forward contract is a commitment to
    purchase or sell a foreign currency at a future date, at a negotiated rate.
    Additionally, the Fund may enter into such contracts to hedge certain other
    foreign currency denominated investments. These contracts are recorded at
    market value, and the related realized and unrealized foreign exchange gains
    and losses are included in the statement of operations. In the event that
    counterparties fail to settle these currency contracts or the related
    foreign security trades, the Fund could be exposed to foreign currency
    fluctuations.

    Each portfolio other than the Money Market Portfolio may (a) write call
    options traded on a registered national securities exchange if such
    portfolio owns the underlying securities subject to such options, and
    purchase call options for the purpose of closing out positions it has
    written, (b) purchase put options on securities owned, and sell such options
    in order to close its positions in put options, (c) purchase and sell
    financial futures and options thereon, and (d) purchase and sell financial
    index options; provided, however, that no option or futures contract shall
    be purchased or sold if, as a result, more than one-third of the total
    assets of the portfolio would be hedged by options or futures contracts, and
    no more than 5% of any portfolio's total assets, at market value, may be
    used for premiums on open options and initial margin deposits on futures
    contracts. Options are recorded at market value, and the related realized
    and unrealized gains and losses are included in the statement of operations.
    The portfolios making use of options bear the market risk of an unfavorable
    change in the price of any security underlying the options.

    The Fund may invest in two kinds of financial futures contracts: stock index
    futures contracts and interest rate futures contracts. Stock index futures
    contracts are contracts developed by and traded on national commodity

   Securities transactions are recorded on a trade date basis. Dividend income
   is recognized on the ex-dividend date (except in the case of foreign
   securities in the International, Small Cap, Global Contrarian, Aggressive
   Growth, Stellar, Blue Chip, and Small Cap Growth Portfolios, in which
   dividends are recorded as soon after the ex-dividend date as the fund becomes
   aware of such dividends), and interest income is accrued daily as earned. Net
   realized gain or loss on investments and foreign exchange transactions are
   determined using the first-in, first-out method except in the case of the
   Aggressive Growth and Growth and Income Portfolios in which the identified
   cost basis is used.

   The books and records of all the portfolios are maintained in U.S. dollars.
   Foreign currency amounts in the International, Small Cap, Global Contrarian,
   Aggressive Growth, Stellar, Blue Chip and Small Cap Growth Portfolios are
   translated into U.S. dollars on the following basis:

   (1) market value of investments, other assets and liabilities -- at exchange
       rates prevailing at the end of the period.

   (2) purchases and sales of investments, income and expenses -- at the rates
       of exchange prevailing on the respective dates of such transaction.

   Although the net assets and the market value of the portfolios are presented
   at the foreign exchange rates at the end of the period, the portfolios do not
   generally isolate the effect of fluctuations in foreign exchange rates from
   the effect of changes in the market price of the investments. However, for
   tax purposes, the portfolios do isolate the effect of fluctuations in foreign
   exchange rates when determining the gain or loss upon sale or maturity of
   foreign-currency denominated debt obligations pursuant to Federal income tax
   regulations.

   Foreign investment and currency transactions may involve certain
   considerations and risks not typically associated with investing in U.S.
   companies and the U.S. Government. These risks, including re-evaluation of
   currency and future adverse political and economic developments, could cause
   investments and their markets to be less liquid and prices more volatile than
   those of comparable U.S. companies and the U.S. Government.

   Each portfolio may acquire repurchase agreements from member banks of the
   Federal Reserve System which ONI deems creditworthy under guidelines approved
   by the Board of Directors, subject to the seller's agreement to repurchase
   such securities at a mutually agreed upon date and price. The repurchase
   price generally equals the price paid by the portfolio plus interest
   negotiated on the basis of current short-term rates, which may be more or
   less than the rate on the underlying portfolio securities. The seller, under
   a repurchase agreement, is required to maintain as collateral for the
   repurchase transaction securities in which the portfolio has a perfected
   security interest with a value not less than 100% of the repurchase price
   (including accrued interest). Securities subject to repurchase agreements are
   held by the Fund's custodian or another qualified custodian or in the Federal
   Reserve/Treasury book-entry system. Repurchase agreements are considered to
   be loans by the portfolio under the 1940 Act.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

   Net investment income (loss) and net realized gains (losses) may differ for
   financial statement and tax purposes primarily due to wash sales and net
   operating losses. The character of distributions made during the period from
   net investment income or net realized gains, if any, may differ from their
   ultimate characterization for federal income tax purposes. On the statement
   of assets and liabilities, as a result of permanent book-to-tax differences,
   the following reclassifications were made in the Small Cap, Aggressive
   Growth, Core Growth and Small Cap Growth Portfolios: accumulated net
   investment loss has been decreased by $187,071, $21,640, $62,638 and $17,952,
   respectively, resulting in a reclassification adjustment to decrease Paid-in
   capital in excess of par value by $187,071, $21,640, $62,638 and $17,952
   respectively. This reclassification has no effect on net assets or net asset
   value per share.

   For Federal income tax purposes, the Bond, Omni, Small Cap, Core Growth,
   Growth and Income, Social Awareness, Strategic Income, Blue Chip, Equity
   Income and Small Cap Growth Portfolios had capital loss carryovers of
   $274,501, $681,856, $4,198,422, $1,632,809, $3,005,094, $622,020, $97,030,
   $18,271, $5,714 and $414,923 respectively, at December 31, 1998. If not
   offset by capital gains, $41,235 will expire in 2003 in the Bond Portfolio,
   $2,893 and $447,567 will expire in 2005 in the Bond and Core Growth
   Portfolios, respectively and $230,373, $681,856, $4,198,422, $1,185,242,
   $3,005,094, $622,022, $97,030, $18,271, $5,714 and $414,923 will expire in
   2006 in the Bond, Omni, Small Cap, Core Growth, Growth and Income, Social
   Awareness, Strategic Income, Blue Chip, Equity Income and Small Cap Growth
   Portfolios, respectively. The Board of Directors does not intend to authorize
   a distribution of any net realized gain for a portfolio until the capital
   loss carryover has been offset or expires.

   It is the policy of the Fund to distribute to its shareholders substantially
   all of its taxable income, thus gaining relief from Federal income taxes
   under provisions of current tax regulations applicable to investment
   companies of this type. Accordingly, no provision for Federal income taxes
   has been made.

   Expenses directly attributable to a portfolio are charged to that portfolio.
   Expenses not directly attributed to a portfolio are allocated on the basis of
   relative net assets.

   The preparation of financial statements in conformity with generally accepted
   accounting principles requires management to make estimates and assumptions
   that affect the reported amounts of assets and liabilities and disclosure of
   contingent assets and liabilities at the date of the financial statements and
   the reported amounts of increases and decreases in net assets from operations
   during the reporting period. Actual results could differ from those
   estimates.

   The gross unrealized appreciation and depreciation on investments in each
   portfolio as of December 31, 1998 were as follows:

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders of
Ohio National Fund, Inc.:

We have audited the accompanying statements of assets and liabilities of Ohio
National Fund, Inc. -- Equity Portfolio, Money Market Portfolio, Bond Portfolio,
Omni Portfolio, International Portfolio, Capital Appreciation Portfolio, Small
Cap Portfolio, Global Contrarian Portfolio, Aggressive Growth Portfolio, Core
Growth Portfolio, Growth & Income Portfolio, S&P 500 Index Portfolio, Social
Awareness Portfolio, Strategic Income Portfolio, Stellar Portfolio, Relative
Value Portfolio, Blue Chip Portfolio, Equity Income Portfolio, High Income Bond
Portfolio, Small Cap Growth Portfolio (collectively, the Funds), including the
schedules of investments, as of December 31, 1998 and the related statements of
operations, statements of changes in net assets and the financial highlights for
the periods indicated in the financial statements and financial highlights
herein. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
verification of securities owned as of December 31, 1998, by confirmation with
the custodians and brokers and other appropriate audit procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Funds at December 31, 1998, the results of their operations, the changes in
their net assets and the financial highlights for the periods indicated herein,
in conformity with generally accepted accounting principles.
