                              INVESTMENT POLICIES
 
Each portfolio has its own investment objective which it seeks through its
separate investment policies. The differences in objectives and policies among
the portfolios affect the risks and returns of each portfolio. We can never be
sure that any portfolio will meet its investment objectives.
 
The investment objectives of each portfolio discussed below and in the Statement
of Additional Information may only be changed if approved by a majority vote of
that portfolio's shareholders. Each portfolio may invest in cash, short-term
obligations and U.S. government securities for defensive purposes during times
of unusual market or economic conditions or pending selection of securities in
accordance with the portfolio's policies. The relatively high portfolio turnover
rates for the Small Cap, Aggressive Growth, Core Growth, Growth & Income, Small
Cap Growth and Strategic Income portfolios result in correspondingly higher
brokerage costs for these portfolios. The Statement of Additional Information
provides a fuller description of the types of financial instruments in which the
Money Market portfolio may invest. It also defines the debt ratings of
nationally recognized statistical rating organizations. It also gives
information about portfolio turnover rates for each portfolio.
 
   
RISKS
    
 
   
The primary risks of investing in each portfolio are:
    
 
   
Market risk refers to how much a security's price is likely to change in
response to changes in conditions in securities markets in general. Markets tend
to move in cycles with periods of rising prices and periods of falling prices.
They can decline for many reasons, including adverse political or economic
developments here or abroad, changes in investor psychology, or heavy
institutional selling. In the case of debt securities, changes in the overall
level of interest rates affect the security's price.
    
 
   
Financial risk refers to the ability of an issuer of a debt security, such as a
bond, to pay principal and/or interest on that security when due. It also refers
to the earnings stability and overall financial soundness of an issuer of an
equity security.
    
 
   
Sector risk is the possibility that a certain group or category of securities
may not perform as well as companies in other sectors or the market as a whole.
When a portfolio concentrates its investments in a limited range of securities,
it is more susceptible to any adverse economic, business or other developments
generally affecting companies in that sector.
    
 
   
All of the portfolios are subject to these risks. You could lose money, or have
less return than the market in general, in any of the portfolios.
    
 
   
Below are the most significant investment policies of each of the portfolios.
Following these are discussions of additional risks of investing in various
kinds of securities in which several or all of the portfolios may invest.
    
 
EQUITY PORTFOLIO
 
The objective of the Equity portfolio is long-term growth of capital. Current
income is a secondary consideration although growth of income may accompany
growth of capital. This portfolio invests primarily in common stocks or
securities that may be converted into, or carry the right to buy, common stocks.
It may also invest in preferred stocks, debt securities and readily marketable
mortgage notes. This portfolio invests primarily in securities listed on
national securities exchanges. From time to time it may also purchase securities
traded in the over-the-counter market and foreign securities.
 
   
The Adviser performs traditional fundamental analysis to select securities
promising long-term value. The Adviser considers each issuer's business and
product strength, its financial condition, its competitive position, its
management expertise, its research and development spending, and the difficulty
of other companies duplicating its products or services. The Adviser primarily
seeks growing companies having a market stipulating over $1 billion. These
    
 
                                        2
<PAGE>   5
 
   
companies are generally among the leaders in their industry or product lines.
The Adviser also considers an issuer's recent stock price performance and
earnings estimates.
    
 
   
Primary risks: This portfolio's primary risks are the market, financial and
sector risks described above.
    
 
The following bar chart and table indicate the risks of investing in the Equity
portfolio. They show changes in the portfolio's performance for each of the last
ten years and the portfolio's average annual returns for the last one year, five
years and ten years compared to those of a broad-based securities market index.
The portfolio's past performance does not necessarily indicate how it will
perform in the future. Variable contract charges are not reflected in the chart
or table. If they were, the returns would be less than those shown.

MONEY MARKET PORTFOLIO
 
The objective of the Money Market portfolio is maximum current income consistent
with preservation of principal and liquidity. This portfolio invests in high
quality money market instruments, including:
 
- - obligations maturing in 13 months or less and issued or guaranteed as to
  principal and interest by the U.S. government, or any agency or authority
  controlled or supervised by and acting as an instrumentality of the U.S.
  government as authorized by Congress;
 
- - commercial paper, certificates of deposit and bankers' acceptances that have
  received the highest rating by any two nationally recognized statistical
  rating organizations ("NRSRO's"), or the highest rating by one NRSRO if that
  is the only NRSRO having rated the security, 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;
 
- - commercial paper, certificates of deposit, bankers' acceptances or other
  corporate obligations maturing in 13 months or less and which, although not
  rated by any NRSRO, the Board of Directors determines to be of a quality
  comparable to that of instruments receiving either of the two highest ratings,
  provided, that any security determined to be comparable in quality to the
  second highest rating shall be included in the 5% limitation below;
 
                                        3
<PAGE>   6
 
- - repurchase agreements with respect to any of these obligations;
 
- - as to no more than 5% of the portfolio's assets, in commercial paper,
  certificates of deposit or bankers' acceptances receiving the second highest
  rating by any two NRSRO's (or by 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, provided, that no more than $1
  million (or 1% of portfolio assets, if greater) may be invested in such
  securities of any one issuer; and
 
- - up to 50% of its assets in the securities of foreign issuers (including
  private issuers and foreign governments or political subdivisions, agencies or
  instrumentalities of foreign governments), provided they meet the above
  quality standards and they are denominated in U.S. dollars and held in custody
  in the United States.
 
The portfolio may only invest in instruments that the Board of Directors
determines present minimal credit risks. Generally, this portfolio holds its
money market securities until maturity. They are then redeemed. The portfolio
normally will not realize any gain or loss on these securities. There may be
times when it is necessary or appropriate to sell securities before they mature
in order to shorten the portfolio's average maturity. This might be necessary to
meet redemptions or because of a reevaluation of an issuer's credit-worthiness.
 
   
Primary risks: The portfolio's rate of return varies as short-term interest
rates vary. The rate of return will also be affected by other factors such as
the portfolio's operating expenses and any sales of portfolio securities before
they mature. Generally, investment in this portfolio involves less market and
financial risk than an investment in any other portfolio of the Fund. However,
it is possible to lose money in this portfolio.
    
 
   
An investment in the Money Market portfolio is not a deposit of any bank. It is
not insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency.
    
 
The following bar chart and table indicate the risks of investing in the Money
Market portfolio. They show changes in the portfolio's performance for each of
the last ten years and the portfolio's average annual returns for the last one
year, five years and ten years. The portfolio's past performance does not
necessarily indicate how it will perform in the future. Variable contract
charges are not reflected in the chart or table. If they were, the returns would
be less than those shown.

BOND PORTFOLIO
 
   
The objective of the Bond portfolio is a high level of income and opportunity
for capital appreciation consistent with preservation of capital. Investments
are primarily in intermediate-term and long-term fixed-income securities. These
generally have a remaining maturity of 5 years or more when purchased.
    
 
At least 80% of the portfolio's assets (other than cash and U.S. government
securities) will be invested in:
 
- - publicly traded, investment grade, non-convertible corporate debt securities
  issued by United States corporations and assigned within the four highest bond
  ratings by Moody's or Standard and Poor's ("S&P"); and
 
- - corporate debt securities used for short-term investment and limited to the
  top grade of these two rating services.
 
Up to 20% of the portfolio's assets may be invested in:
 
- - securities having high potential for capital appreciation;
 
- - preferred stocks, convertible securities and securities carrying warrants to
  purchase equity securities; and
 
- - debt securities issued by U.S. banks and savings and loan associations which
  at the date of investment have capital, surplus and undivided profits as of
  the date of their most recent financial statements in excess of $100 million.
 
This portfolio does not invest in common stocks directly. It may retain for
reasonable periods of time up to 10% of its total assets in common stocks
acquired by converting debt securities or exercising warrants acquired with debt
securities.
 
This portfolio normally includes debt securities with varying maturities
selected from various industries, depending upon the Adviser's evaluation of
current and anticipated market conditions.
 
   
Primary risks: The market values of debt instruments vary depending upon their
respective yields. Therefore, the portfolio's net asset value per share changes
from time to time as the general level of interest rates changes. Consequently,
an investment in this portfolio involves substantial market risk, but should
involve less financial risk than an investment in any of the portfolios that
invest primarily in common stocks.
    
 
   
The following bar chart and table indicate the risks of investing in the Bond
portfolio. They show changes in the portfolio's performance for each of the past
ten years and the portfolio's average annual returns for the last one year, five
years and ten years compared to those of a broad based securities market index.

perform in the future. Variable contract charges are not reflected in the chart
or table. If they were, the returns would be less than those shown.

OMNI PORTFOLIO
    
 
The objective of the Omni portfolio is a high level of long-term total return
consistent with preservation of capital by investing in stocks, bonds and money
market instruments. Total rate of return consists of current income including
dividends, interest and discount accruals and capital appreciation.
 
The Adviser adjusts the mix of investments from time to time among the various
market sectors (stocks, bonds and money market instruments) to capitalize on
perceived variations in return potential of changing market and economic
conditions. Sometimes the portfolio may not be invested in all three of the
market sectors.
 
The portfolio's principal investment objective is supplemented and limited by
the investment objectives, policies and restrictions established for each of the
market sectors. Within the stock sector, the Adviser seeks long-term growth of
capital. Current income is a secondary goal for the stock sector. Within the
bond sector, the Adviser seeks a high level of income. Capital appreciation,
consistent with capital preservation is a secondary goal of the bond sector.
Within the money market sector, the Adviser seeks maximum current income
consistent with the preservation of principal and liquidity.
 
   
Primary risks: Investment in this portfolio involves all of the risks associated
with investing in portfolios concentrating in each of the three sectors. There
is also the risk that at any given time this portfolio will invest too much or
too little in each sector. On the other hand, since the risk factors affecting
each sector are different, the risks of each sector often offset one another. As
a result, this portfolio is sometimes less volatile than a portfolio investing
only in stocks or bonds.
    
 
The following bar chart and table indicate the risks of investing in the Omni
portfolio. They show changes in the portfolio's performance for each of the past
ten years and the portfolio's average annual returns for the last one year, five
years and ten years compared to those of a broad-based securities market index.

INTERNATIONAL PORTFOLIO
 
The objective of the International portfolio is total return on assets by
investing primarily in securities of foreign companies. A substantial part of
the portfolio's assets are stocks of established companies in economically
developed countries. Normally, most of its investments are in stocks denominated
in foreign currencies. It may invest in depository receipts. It may invest in
investment grade fixed-income securities and foreign government securities. It
may enter into forward commitments and foreign currency transactions. It may
maintain reserves in foreign or U.S. money market instruments. This portfolio is
managed by Federated Global Investment Management Corp. ("FGIM") under a
subadvisory agreement with the Adviser.
 
   
In selecting portfolio securities, FGIM uses its own quantitative process to
rank the future performance potential of companies. FGIM evaluates each
company's earnings potential in light of its current valuation. It then
evaluates management quality. It may examine a company's suppliers, customers
and competitors. It also reviews the company's financial statements and earnings
forecasts. It evaluates the sustainability of the company's current growth
trends.
    
 
   
This portfolio enables you to diversify your investment by participating in
developed foreign economies and markets. If you also invest in domestic
portfolios, the International portfolio may reduce the overall volatility of
your investments because foreign countries often have business cycles, economic
policies and securities markets that do not move in harmony with those in the
United States.
    
 
   
Primary risks: In addition to financial risk, market risk and sector risk, this
portfolio is subject to the special risks of Foreign Investments described
following these brief summaries of each portfolio's investment policies.

INTERNATIONAL SMALL COMPANY PORTFOLIO
 
   
The objective of the International Small Company portfolio is long-term growth
of capital by investing primarily in equity securities of foreign companies
having a market capitalization at time of purchase of $1.5 billion or less. Any
income received from investments is incidental. The portfolio invests in
companies located throughout the world, in both developed economies and emerging
markets. Investments will also include interests in entities such as limited
partnerships, limited liability companies and business trusts. These foreign
entities often issue securities comparable to common or preferred stock. This
portfolio is managed by FGIM under a subadvisory agreement with the Adviser.
    
 
Investments in foreign small companies enable you to further diversify the
investments you have in foreign markets. Price changes of small companies do not
always follow those of larger companies.
 
   
Primary risks: Generally, the prices of small company securities tend to be more
volatile and present more risk than those of larger companies. This is
especially true in the short term. In addition to financial risk, market risk
and sector risk, this portfolio is subject to the special risks of Foreign
Investments and Small Capitalization Companies described following these brief
summaries of each portfolio's investment policies.
    
 
   
In selecting portfolio securities, FGIM uses its own quantitative process to

portfolio was Societe Generale Asset Management Corp. until the end of 1998. In
1999, the portfolio's investment policies were substantially changed and its
name was changed from the "Global Contrarian" portfolio.

CAPITAL APPRECIATION PORTFOLIO
 
   
The objective of the Capital Appreciation portfolio is to seek maximum long-term
capital appreciation through investment primarily in common stocks. This
portfolio is managed by T. Rowe Price Associates, Inc. ("TRPA") under a
subadvisory agreement with the Adviser.
    
 
   
This portfolio invests primarily in:
    
 
   
- - common stocks of established companies that TRPA believes have above-average
  potential for capital growth;
    
 
   
- - long-term core holdings in companies whose prices, at the time purchased by
  the portfolio, were considered low in terms of company assets, earnings or
  other factors;
    
 
                                        9
<PAGE>   12
 
   
- - opportunistic investments whose prices are expected to rise in the short term
  but not necessarily over the long term; and
    
 
   
- - stocks that seem undervalued by various measures, such as price/book value,
  and may be temporarily out of favor, but appear to have good prospects for
  capital appreciation.
    
 
   
Since TRPA attempts to prevent losses as well as achieve gains, it typically
uses a value approach in selecting investments. It may establish relatively
large positions in companies it finds attractive.
    
 
A substantial part of this portfolio is also invested in fixed income
securities. These include corporate bonds, U.S. government securities, preferred
stock, warrants, securities convertible into common stock, and money market
instruments. The portfolio's total return consists principally of capital
appreciation (or depreciation) and, to a lesser extent, current income.
 
   
Primary risks: A sizable cash or fixed income position may keep the portfolio
from participating in a strong, rapidly rising bull market. Significant exposure
to bonds increases the risk that the portfolio's performance could be hurt by
rising interest rates or credit downgrades or defaults. A particular risk of
this portfolio's value or "contrarian" approach is that some holdings may not
recover and provide the capital growth anticipated.
    
 
   
The following bar chart and table indicate the risks of investing in the Capital
Appreciation portfolio. They show changes in the portfolio's performance for
each of the complete calendar years since the portfolio's inception and the

SMALL CAP PORTFOLIO
    
 
   
The objective of the Small Cap portfolio is maximum capital growth. The
portfolio invests primarily in the common stocks of small and medium sized
companies. Ordinarily, these companies are not listed on a national securities
exchange but will be traded over the counter. Under normal market conditions, at
least 65% of the portfolio's assets invested in common stocks of companies with
market capitalizations of less than $1.5 billion. However it may also invest in
larger companies if they appear to present better prospects for capital growth.
This portfolio may invest up to 30% of its assets in foreign securities. This
portfolio is managed by Founders Asset Management LLC ("FAM") under a
subadvisory agreement with the Adviser.
    
 
Investments in both this portfolio and one or more portfolios investing
primarily in larger companies enable you to diversify your investments. Price
changes of small companies do not always follow those of larger companies.
 
   
Primary risks: Generally, the prices of small company securities tend to be more
volatile and present more risk than those of large companies. This is especially
true in the short term. The special risks of investing in Small Capitalization
Companies are described following these brief summaries of each portfolio's
investment policies.

AGGRESSIVE GROWTH PORTFOLIO
 
The objective of the Aggressive Growth portfolio is capital growth. The
portfolio invests in a variety of securities that the subadviser believes have
attractive growth opportunities. The portfolio normally emphasizes equity
securities.
 
                                       11
<PAGE>   14
 
However, it may invest in any type of security that the subadviser believes has
the potential for capital appreciation. The portfolio may invest most or all of
its assets in common stocks, preferred stocks, securities that are convertible
into common or preferred stocks, and warrants. At other times, the portfolio may
invest most or all of its assets in intermediate -- to long-term corporate or
U.S. government debt securities.
 
Although the debt securities in which the portfolio invests are primarily
investment-grade debt securities, it may invest up to 5% of its assets in
non-investment-grade debt securities ("junk" bonds"). The portfolio may invest
up to 15% of its assets in foreign securities. These involve certain additional
risks as described following these brief summaries of each portfolio's
investment policies. This portfolio is managed by Strong Capital Management,
Inc. ("SCM") under a subsidiary agreement with the Adviser.
 
SCM seeks emerging investment trends and growth opportunities. SCM tries to
identify companies poised for accelerated earnings growth due to innovative
products or services, new management, or favorable economic or market cycles.
These companies may be small, unseasoned firms in the early stages of
development, or they may be mature organizations.
   
Primary risks: The portfolio engages in substantial short-term trading. This
involves significant risk and may be deemed speculative. Frequent trading also
results in a higher portfolio turnover rate and correspondingly higher brokerage
costs. The special risks of investing in Small Capitalization Companies are
described following these brief summaries of each portfolio's investment
policies.

CORE GROWTH PORTFOLIO
 
The objective of the Core Growth portfolio is long-term capital appreciation.
The portfolio invests primarily in stocks of large, medium and small companies
that the subadviser believes have strong prospects for earnings growth and
long-term capital appreciation. The subadviser seeks companies poised for rapid
growth that have a history of above-average earnings growth, demonstrate the
ability to sustain that growth, and operate in industries or markets
experiencing increased demand for their products or services. This portfolio is
managed by Pilgrim Baxter & Associates, Ltd. ("PBA") under a subadvisory
agreement with the Adviser.
 
In managing this portfolio, PBA uses both quantitative and fundamental
processes. They focus on quality earnings growth. PBA begins by making a list of
rapidly growing companies having desired quality characteristics. PBA derives
this list of companies by using its proprietary software and research models.
These models incorporate attributes of successful growth (such as positive
earnings surprises, upward earnings estimate revisions, and accelerating sales
and earnings growth). Then, using fundamental research, PBA evaluates each
company's earnings quality and assesses the sustainability of the company's
current growth trends. Through this highly disciplined process, PBA tries to
find investments with strong growth characteristics.
 
   
Primary risks: This portfolio's investments in small and medium capitalization
companies may experience greater price volatility than portfolios investing
primarily in larger, more established companies. If you consider investing in
this portfolio, you need to maintain a long-term investment perspective because
the companies in which this portfolio invests will experience stock price
volatility.

GROWTH & INCOME PORTFOLIO
 
The objective of the Growth & Income portfolio is long-term total return. The
portfolio invests primarily in equity and debt securities, focusing on small-and
mid-cap companies that offer the potential for capital appreciation, current
income, or both. This portfolio is managed by Robertson Stephens Investment
Management, L.P. ("RSIM") under a subadvisory agreement with the Adviser.
 
The portfolio normally invests the majority of its assets in common stocks,
convertible securities, bonds, and notes. Although the portfolio focuses on
companies with market capitalizations of up to $3 billion, it may invest in
larger companies. The portfolio may engage in short sales of securities expected
to decline in price.
 
   
Primary risks: Small- and mid-cap companies may present greater opportunities
for investment return than do larger companies, but may also involve greater
risks. The special risks of investing in Small Capitalization Companies are
described following these brief summaries of each portfolio's investment
policies. To a large extent the same risk factors apply to investments in
mid-cap companies.

SMALL CAP GROWTH PORTFOLIO
 
The objective of the Small Cap Growth portfolio is capital appreciation. It is
managed by RSIM under a subadvisory agreement with the Adviser. It invests in an
actively managed portfolio of equity securities (principally common stocks) of
small cap growth companies. These are companies that, in RSIM's opinion, have
the potential, based on superior products or services, operating
characteristics, and financing capabilities, for more rapid growth than the
over-all economy. Investments generally are held in companies in industry
segments experiencing rapid growth or in companies with proprietary advantages.
In evaluating potential investments, RSIM may consider a number of factors
including the rate of earnings growth, the quality of management, the extent of
proprietary operating advantage, the return on equity and/or the financial
condition of the company.
 
   
Primary risks: Small companies may present greater opportunities for investment
return than do larger companies. However, they also involve greater risks. Up to
30% of this portfolio's assets may be invested in foreign securities. The
special risks of Foreign Investments and Small Capitalization Companies are
described following these brief summaries of each portfolio's investment
policies.
    
 
This portfolio began its operations in May 1998.

S&P 500 INDEX PORTFOLIO
 
The objective of the S&P 500 Index portfolio is total return approximating that
of the Standard & Poor's 500 Index ("S&P 500"(R)) including reinvestment of
dividends, at a risk level consistent with that of the S&P 500. It seeks this
objective by investing primarily in:
 
- - common stocks and other securities that need not be included among the 500
  stocks in the S&P 500, and/or
 
- - S&P 500 stock index futures contracts hedged by investing in securities issued
  or guaranteed by the U.S. government, its agencies or instrumentalities,
  investment-grade corporate bonds and money market instruments.
 
This strategy is intended to replicate the performance of the S&P 500. However,
portfolio expenses reduce the portfolio's ability to exactly track the S&P 500.
There can be no assurance that the portfolio's investments will have the desired
effect.
 
The value of S&P 500 stock index futures contracts is tied directly to the
fluctuations of the S&P 500. The portfolio's ability to use futures contracts as
a substitute for maintaining a fully-invested market position in the 500 stocks
comprising the S&P 500 obligates the portfolio to hedge its position by
delivering a specific dollar amount equal to the difference between the value of
the S&P 500 at the time the contract was made and the closing of the contract.
The futures contracts can result in a high degree of leverage so that a
relatively small decline in the S&P 500 could result in a substantial loss to
the portfolio, including part or all of the margin deposits required on the
contracts. The portfolio seeks to offset that risk by maintaining its
investments in U.S. government obligations, investment-grade corporate bonds and
money market instruments. The income from these investments tends to offset the
costs of the futures contracts.
 
   
Primary risks: The risks involved with Hedging Techniques are described
following these brief summaries of each portfolio's investment policies. This
portfolio is subject to significant sector risk.

HIGH INCOME BOND PORTFOLIO
 
The objective of the High Income Bond portfolio is high current income. The
portfolio invests primarily in lower rated corporate debt obligations commonly
referred to as "junk bonds." Some of these fixed income securities may involve
equity features. Capital growth will be considered, but only when consistent
with the objective of high current income. Normally, the portfolio will not
invest more than 10% of its assets in equity securities. Lower rated debt
securities are subject to a greater risk of loss of principal and interest than
investments in higher rated bonds. You should carefully assess the risks
associated with this portfolio before investing.
 
This portfolio is managed by Federated Investment Counseling ("FIC") under a
subadvisory agreement with the Adviser.
 
   
Low-rated debt securities have higher yields because of their greater
uncertainty of default. FIC seeks to reduce this financial risk through careful
security selection and diversification by both company and industry. FIC looks
for bonds offering superior potential returns for the financial risk assumed.
FIC's analysis focuses on the issuer's financial condition, competitive position
and management expertise. FIC also considers current economic, market and
industry factors affecting the issuer. FIC typically does not consider interest
rate risks because the prices of high yield bonds are influenced much more by
financial risks, including potential default, than by changes in the general
level of interest rates.
    
 
Fixed income securities in which the portfolio invests include preferred stocks,
bonds, debentures, notes, equipment lease certificates and equipment trust
certificates. The portfolio's investments are generally rated Baa or lower by
 
                                       17
<PAGE>   20
 
Moody's, or BBB or lower by S&P or Fitch, or are not rated but are determined by
FIC to be of comparable quality, and may include bonds in default. There is no
lower limit with respect to rating categories for securities in which the
portfolio may invest. These lower rated securities have speculative
characteristics. Changes in economic conditions or other circumstances are
likely to make it more difficult for the companies issuing the bonds to make
principal and interest payments than is the case with companies issuing highly
rated bonds.
 
The portfolio may invest in various kinds of convertible securities that can be
exchanged for or converted into common stock. Convertible securities are often
rated below investment grade or not rated because they fall below debt
obligations and just above common stock in order of preference on the issuer's
balance sheet. The portfolio may invest its assets in foreign securities,
including those not publicly traded in the United States. The portfolio may also
invest in real estate investment trusts.
 
   
Primary risks: The special risks of investing in Lower Rated Debt Securities,
Convertible Securities and Real Estate Securities are described following these
brief summaries of each portfolio's investment policies. There is a relatively
higher risk that an issuer of low rated bonds will default by failing to pay
interest or principal when due. If that happens, the portfolio loses money.
Low-grade bonds are usually uncollateralized and they are subordinate to the
issuer's other outstanding debt.
    
 
This portfolio began its operations in May 1998
 
EQUITY INCOME PORTFOLIO
 
The objective of the Equity Income portfolio is above-average income and capital
appreciation. The portfolio invests primarily in income-producing equity
securities including common stocks, preferred stocks, real estate investment
trusts and securities (including debt securities) convertible into common
stocks. The portfolio emphasizes those common stocks in each sector that have
good value, attractive yield and dividend growth potential. The portfolio is
managed by FIC under a subadvisory agreement with the Adviser.
 
   
FIC performs a technical review of potential issuers. It examines mostly
companies with market capitalization over $1 billion which it believes are
trading at low valuation in relation to their historic market prices and
projected earnings. The portfolio's equity securities generally have a history
and expectation of paying increasing dividends.
    
 
   
FIC performs traditional fundamental analysis to select securities promising
long-term value. It focuses on the current financial condition of the issuer. It
examines the issuer's product strength, competitive position and management
expertise. FIC also considers current economic, market and industry factors
affecting the issuer. FIC uses the "value" style of investing. It selects
securities with a comparatively low volatility in share price relative to the
overall market and which may provide relatively high dividend income. With this
style of investing, the prices of portfolio securities may not always increase
as rapidly as stocks selected for their growth characteristics because FIC's
investment approach is sector-neutral.
    
 
The portfolio invests in convertible securities without regard to their rating.
Convertible securities are used because they typically offer high yields and
good potential for capital appreciation. They are often rated below investment
grade, or not rated, because they fall below debt obligations and just above
common equity in order of preference or priority on the issuer's balance sheet.
Hence, an issuer with investment grade senior debt may issue convertible
securities with ratings below investment grade or not rated.
 
   
Primary risks: Convertible securities may be subject to some of the same risks
as those inherent in junk bonds as described for the High Income Bond portfolio.
This portfolio may invest in foreign securities, and it may also engage in short
sales from time to time. The special risks of investing in Convertible
Securities and Foreign Investments, and engaging in Short Sales, are described
following these brief summaries of each portfolio's investment policies.
    
 
This portfolio began its operations in May 1998.

BLUE CHIP PORTFOLIO
 
The objective of the Blue Chip portfolio is growth of capital and income by
investing primarily in securities of high quality companies. The portfolio is
managed by FIC under a subadvisory agreement with the Adviser.
 
FIC selects investments for this portfolio principally on the basis of
fundamental research techniques and standards with emphasis on earning power,
financial condition and valuation. The companies are among the leaders in their
industries in sales, earnings, and/or market capitalization.
 
   
FIC performs traditional fundamental analysis to select securities promising
long-term value. It focuses on the current financial condition of the issuer. It
examines the issuer's product strength, competitive position and management
expertise. FIC also considers current economic, market and industry factors
affecting the issuer. FIC uses the "value" style of investing. It selects
securities that are trading at low valuation in relation to their historic
market prices and projected growth. With this style of investing, the prices of
portfolio securities may not always increase as rapidly as stocks selected for
their growth attributes.
    
 
The portfolio invests in common stocks, preferred stocks, corporate debt
obligations, convertible securities, warrants, American depository receipts and
foreign securities. Corporate debt obligations will be rated Baa or better by
Moody's, or BBB or better by S&P or Fitch, or if not rated, will be determined
by FIC to be of comparable quality. If a security loses its rating or has its
rating reduced after the portfolio has purchased it, FIC does not need to drop
the security from the portfolio, but that will be considered. Bonds rated Baa,
BBB or better are considered investment grade. Those rated below that have some
speculative characteristics.
 
   
Primary risks: This portfolio's primary risks are market risk and sector risk,
described on page 2.
    
 
This portfolio began its operations in May 1998.
 
SOCIAL AWARENESS PORTFOLIO
 
The objective of the Social Awareness portfolio is long-term growth of capital.
It invests primarily in the common stocks and other equity 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.
 
In choosing investments, the Adviser considers a company's record in:
 
- - quality and safety of its products and services,
 
- - environmental protection and enhancement,
 
- - employee relations, opportunities and safety,
 
- - consumer relations and protection,
 
- - community involvement, and
 
- - expectations for the creation of new jobs and economic development due to
  anticipated company growth.
 
Each potential investment is also subject to the Adviser's standards of
investment analysis. As a matter of operating policy, the portfolio will not
invest in any company substantially engaged in the manufacture of or
distribution of tobacco products, alcoholic beverages or weapons, or the
operation of gambling casinos, or the support of repressive regimes. This policy
may be modified by the Board of Directors.
 
The Adviser monitors and responds to changes in business practices of the
companies selected for investment. In case of any adverse development, the
Adviser considers whether or not the portfolio's policies require it to sell its
position in that company. Any sale under those circumstances is, however,
subject to prudent market considerations.

This portfolio is managed by Firstar Bank, N.A. ("Firstar") under a subadvisory
agreement with the Adviser. Firstar selects the core assets based on the outlook
for interest rates and their yield in relation to other fixed income securities
of similar quality and maturity. They only include investment grade bonds. These
are bonds rated Baa or higher by Moody's, or BBB or higher by S&P or Fitch or
which, if unrated, are deemed by Firstar to be of comparable quality.
 
The foreign bonds are issued by non-U.S. companies and governments. They are
investment grade, are denominated in currencies other than U.S. dollars and may
include American Depository Receipts and International Depository Receipts. The
portfolio may also invest in shares of investment companies that invest
primarily in foreign bonds.
 
REITs include equity or mortgage REITs integrated to capture income diversified
by sector (e.g., shopping malls, apartment buildings and health care facilities)
and by geographic location.
 
The domestic equity category consists of high-dividend common and preferred
stocks of U.S. companies with a history of stable earnings and/or growing
dividends. The domestic equity category may also include warrants and securities
convertible into the common stocks of these U.S. companies.
 
The money market category includes:
 
- - commercial paper and Europaper (dollar-denominated commercial paper issued
  outside the U.S.) having at least one rating in one of the two highest
  categories of any NRSRO;
 
- - instruments of domestic and foreign banks and savings and loans (such as
  certificates of deposit, demand and time deposits, savings shares and bankers
  acceptances) if they have capital, surplus and individual profits of over $100
  million, or if the principal amount of the instrument is insured by a fund
  administered by the Federal Deposit Insurance Corporation ("FDIC insured"),
  including Eurodollar Certificates of Deposit ("ECDs"), Yankee Certificates of
  Deposit ("Yankee CDs") and Eurodollar Time Deposits ("ETDs");
 
   
- - obligations of the U.S. government or its agencies or instrumentalities;
    
 
- - repurchase agreements, and
 
- - other unrated short-term instruments deemed by Firstar to be of comparable
  quality to the other obligations in which the portfolio may invest.
 
This portfolio may also engage in short sales from time to time.
 
   
Primary risks: The special risks of investing in Foreign Investments and Real
Estate Securities, and engaging in Short Sales, are described following these
brief summaries of each portfolio's investment policies. This portfolio is
particularly susceptible to sector risks, described on page 2.

FIRSTAR GROWTH & INCOME PORTFOLIO
    
 
   
The objective of the Firstar Growth & Income portfolio is both reasonable income
and long-term capital appreciation. The portfolio invests in income producing
securities including dividend-paying common and preferred stocks as well as
fixed-income securities in order to generate reasonable income. Capital
appreciation is sought through investments in common stocks, particularly those
of medium to large sized domestic companies whose stock is paying dividends. No
more than 25% of the portfolio will be invested in foreign securities. The
portfolio is managed by Firstar Investment Research Management Company, LLC
("FIRMCO") under a subadvisory agreement with the Adviser.
    
 
   
Primary risks: The primary risks of this portfolio are market risk, financial
risk and sector risk.

RELATIVE VALUE PORTFOLIO
 
The objective of the Relative Value portfolio is to obtain the highest total
return that is consistent with reasonable risk. The portfolio invests primarily
in stocks which Firstar believes will have low volatility, above-average yields,
and are undervalued relative to the stocks comprising the S&P 500. Unless it is
in a defensive position, at least 70% of the portfolio's assets will be invested
in common stocks of companies whose revenues are in the top 25% of their
industries. However, other factors, such as product position or market share,
will also be considered and may outweigh revenues.
 
The portfolio also invests in fixed income securities. These include:
 
- - convertible securities;
 
- - investment grade domestic corporate debt obligations that are rated or A or
  higher by Moody's, S&P or Fitch; and
 
- - obligations of the U.S. government or its agencies or instrumentalities.
 
This portfolio is managed by Firstar under a subadvisory agreement with the
Adviser.
 
   
Primary risks: The primary risks of this portfolio are market risk, financial
risk and sector risk.

                          RISKS OF CERTAIN INVESTMENTS
    
 
The kinds of investments described on the following pages can be made by most of
the portfolios. These risk considerations and others are further explained in
the Statement of Additional Information.
 
MIXED AND SHARED FUNDING
 
In the future, it could possibly be disadvantageous for both variable life and
variable annuity separate accounts to invest in the Fund. ONLI, ONLAC and the
Fund do not currently foresee any such disadvantage. The Board of Directors will
monitor events to identify any material conflict between variable life and
variable annuity contract owners. If that happens, the Board will determine what
action, if any, should be taken. This action could include the withdrawal of a
separate account from participation in the Fund. Material conflicts could result
from such things as:
 
- - changes in state insurance law;
 
- - changes in federal income tax law;
 
- - changes in the investment management of any portfolio; or
 
- - differences between voting instructions given by variable life and variable
  annuity contract owners.
 
                                       24
<PAGE>   27
 
The Fund may be used in the future to support benefits under other types of
contracts or for other purposes. Fund shares are not now, and without a change
in applicable law will never be, offered directly to the public. ONLI's and
ONLAC's separate accounts are the sole Fund shareholders. ONLI and ONLAC will
vote the Fund shares attributable to your contracts as you direct.
 
SMALL CAPITALIZATION COMPANIES
 
Small capitalization companies generally have a market capitalization of less
than $1.5 billion. (Market capitalization is the number of shares outstanding
for a company multiplied times the price per share.) These companies are often
still in their developing stage. Small companies are often selected for
investment in a portfolio because the Adviser or subadivser believes the
companies can achieve rapid growth in sales, earnings and share prices. They
often do not pay dividends.
 
Small companies usually present more share price volatility and risk than do
larger, more established companies. Smaller and newer companies often have
limited product lines, markets and financial resources. Their management often
depends on one or a few key people. Their securities may be subject to more
abrupt or erratic price changes than those of larger companies or the market
averages. Often, there is less publicly available information for smaller
companies than for larger ones. Small company securities are sometimes less
liquid than those of larger companies. This is because they have fewer shares
outstanding and they trade less often. That might make it harder for a portfolio
to buy or sell significant amounts of a small company's shares, or those
transactions might impact the shares' market prices unfavorably.
 
All of the portfolios except Money Market and Blue Chip can invest in small
companies. The International Small Company, Small Cap, Aggressive Growth, Core
Growth, Growth & Income, and Small Cap Growth portfolios may concentrate their
investments in these securities
 
FOREIGN INVESTMENTS
 
Investments in foreign securities involve risks not normally associated with
investing in domestic issuers. These include:
 
- - changes in currency rates
 
- - currency exchange control regulations
 
- - seizure or nationalization of companies
 
- - political or economic instability
 
- - unforeseen taxes
 
- - difficulty of obtaining or interpreting financial information under foreign
  accounting standards
 
- - trading in markets that are less efficient than in the U.S.
 
- - lack of information regarding securities issuers
 
- - imposition of legal restraints affecting investments
 
- - reversion to closed markets or controlled economies
 
- - national economies based on a few industries or dependent on revenue from
  certain commodities
 
- - local economies and/or markets vulnerable to global conditions
 
- - volatile inflation rates and debt burdens
 
- - less regulatory protection.
 
                                       25
<PAGE>   28
 
   
Many of these factors are more likely to occur in emerging or developing
countries and may cause abrupt and severe price declines. These factors are
generally less typical of the developed counties.
    
 
In selecting foreign investments, the Adviser and subadvisers seek to minimize
these risks. They select investments in securities appearing to have
characteristics and qualities comparable to the kinds of domestic securities in
which the portfolio may invest.
 
All of the portfolios can invest in foreign securities, although foreign
securities purchased by the Money Market portfolio must be denominated in U.S.
dollars and held in custody in the United States. The International and
International Small Company portfolios may be invested entirely in foreign
securities.
 
REPURCHASE AGREEMENTS
 
Under a repurchase agreement, a portfolio purchases a security and obtains a
simultaneous commitment from the seller to repurchase the security at a mutually
agreed upon price and date. The seller is a member bank of the Federal Reserve
System or a government securities dealer recognized by the Federal Reserve
Board. This may also be viewed as a loan of money by the portfolio to the
seller. The resale price is normally greater than the purchase price and
reflects an agreed upon interest rate. The rate is effective for the period of
time the portfolio is invested in the agreement. It is not related to the coupon
rate on the purchased security.
 
Although repurchase agreements carry certain risks not associated with direct
investments in securities, the Fund enters into repurchase agreements only with
financial institutions believed by the Adviser or subadviser to present minimal
credit risks in accordance with criteria established by the Fund's Board of
Directors. The Adviser and subadvisers review and monitor the creditworthiness
of sellers under the Board's general supervision. The Fund only enters into
repurchase agreements under master repurchase agreements that require that all
transactions are fully collateralized and that the Fund have possession of the
collateral. These agreements must also provide that the Fund will always
receive, as collateral, securities whose market value, including accrued
interest, will be at least equal to 100% of the amount invested in each
agreement. The portfolio only pays for such securities upon physical delivery or
evidence of book entry transfer to the account of the Fund's custodian.
 
If the seller were to default, the portfolio might incur a loss if the value of
the collateral securing the repurchase agreement declines. A portfolio might
also incur disposition costs when liquidating the collateral. If the seller goes
bankrupt, the portfolio might have a delay in obtaining its collateral. The
portfolio would then have a loss if the collateral declines in value.
 
All of the portfolios may invest in repurchase agreements. The period of these
repurchase agreements is usually short, from overnight to one week. At no time
will a portfolio invest in repurchase agreements for more than one year. These
transactions enable a portfolio to earn a return on temporarily available cash.
The Strategic Income portfolio may invest more than 10% of its assets in
agreements maturing in more than seven days.
 
CONVERTIBLE SECURITIES
 
Convertible securities can be exchanged for or converted into common stock.
These include convertible bonds or debentures, convertible preferred stock,
units consisting of usable bonds and warrants, and securities that cap or
otherwise limit returns to the security holder. Examples of these include
dividend enhanced convertible stock or debt exchangeable for common stock
(DECS), liquid yield option notes (LYONS), preferred equity redemption
cumulative stock (PERCS), preferred redeemable increased dividend securities
(PRIDES) and zero coupon convertible securities.
 
As with all fixed-income securities, various market forces influence the market
value of convertible securities, including changes in the level of interest
rates. As the level of interest rates increases, the market value of convertible
securities may decline. Conversely, as interest rates decline, the market value
of convertible securities may increase. The unique investment characteristic of
convertible securities is the right to be exchanged for the issuer's common
stock. This
 
                                       26
<PAGE>   29
 
causes the market value of convertible securities to increase when the
underlying common stock increases. However, since securities prices fluctuate,
there can be no assurance of capital appreciation. Most convertible securities
will not reflect quite as much capital appreciation as their underlying common
stocks. When the underlying common stock price goes down, the value of the
convertible security tends to decline to about the level of the
yield-to-maturity basis of straight nonconvertible debt of similar quality. This
is often called "investment value." The convertible security then may not
experience the same decline as the underlying common stock.
 
Many convertible securities sell at a premium over their conversion values. The
conversion value is the number of shares of common stock to be received upon
conversion multiplied by the current market price of the stock. This premium is
the price investors are willing to pay for the privilege of purchasing a
fixed-income security with a possibility of capital appreciation due to the
conversion privilege. The premium may not be recovered if this appreciation
potential is not realized.
 
All of the portfolios other than the Money Market portfolio can purchase
convertible securities.
 
WARRANTS
 
Warrants are options to purchase common stock at a specific price. They are
valid for a specific period of time. They usually sell at a premium above the
market value of the optioned common stock. Warrants may have a life ranging from
less that a year to twenty years or they may even be perpetual. However, after
they expire they are worthless. If the market price of the common stock does not
exceed the warrant's exercise price during the life of the warrant, the warrant
will expire as worthless. Warrants have no voting rights, pay no dividends, and
have no rights in the assets of the corporation issuing them. The percentage
increase or decrease in the market price of the warrant may tend to be greater
than the percentage increase or decrease in the market price of the optioned
common stock.
 
All of the portfolios other than the Money Market portfolio can purchase
warrants.
 
RESTRICTED AND ILLIQUID SECURITIES
 
Restricted securities are subject to restrictions on resale under federal
securities law. Each of the Equity, Money Market, Bond and Omni portfolios may
invest up to 10% of its assets in illiquid securities. Each of the other
portfolios may invest up to 15% in illiquid securities. Under criteria
established by the Board of Directors, certain restricted securities are deemed
to be liquid. The Directors consider the following criteria in determining the
liquidity of restricted securities:
 
- - the frequency of trades and quotes for the security;
 
- - the number of dealers willing to purchase or sell the security, and the number
  of other potential buyers;
 
- - dealer undertakings to make a market in the security; and
 
- - the nature of the security and the nature of the marketplace trades.
 
HEDGING TECHNIQUES
 
Each portfolio (other than the Money Market portfolio) may, for hedging
purposes, buy and sell various kinds of put and call options, financial futures
contracts, index futures contracts, forward foreign currency contracts, foreign
currency options and foreign currency futures contracts. The use for hedging
purposes of options and futures contracts on securities and foreign currencies
involves certain risks. These include:
 
- - whether the Adviser or subadviser can predict correctly the direction of
  changes in stock prices, interest rates, currency prices and other economic
  factors,
 
- - whether there is enough market liquidity to permit a portfolio to close out
  positions taken, and
 
                                       27
<PAGE>   30
 
- - whether price changes in portfolio securities subject to a hedge follow price
  changes in securities or currencies underlying options and futures contracts.
 
None of these can be assured. A more complete discussion of the risks involved
with hedging techniques is contained in the Statement of Additional Information.
 
OPTIONS
 
   
The purchaser of an option pays the option writer a "premium" for the option. In
the case of a covered call option written by a portfolio, if the purchaser does
not exercise the call option, the premium will generate additional capital gain
to the portfolio. If the market price of the underlying security declines, the
premium received for the call option will reduce the amount of the loss the
portfolio would otherwise incur. However, if the market price of the underlying
security rises above the exercise price and the call option is exercised, the
portfolio will lose its opportunity to profit from that portion of the rise
which is in excess of the exercise price plus the option premium. Therefore, a
portfolio may write call options when the Adviser or subadviser believes that
the option premium will yield a greater return to the portfolio than might occur
on the underlying security during the life of the option.
    
 
   
In the case of a put option purchased by a portfolio, if the market price of the
underlying security remains or rises above the exercise price of the option, the
portfolio will not exercise the option and the premium paid for that option will
reduce the gain the portfolio would otherwise have earned. Conversely, if the
market price of the underlying security falls below the exercise price, less the
premium paid for the option, the portfolio will exercise the option. This will
reduce the loss the portfolio would have otherwise suffered. Therefore, a
portfolio may purchase put options when the Adviser or subadviser believes that
the market price of the underlying security is more likely to decrease than
increase or as a hedge against a decrease in the price of a security held by the
portfolio.
    
 
Whenever a portfolio enters into a closing transaction, the portfolio will
realize a gain (or loss) if the premium plus commission it pays for a closing
call option is less (or greater) than the premium it received on the sale of the
original call option. Conversely, the portfolio will realize a gain (or loss) if
the premium it receives, less commission, for a closing put option is greater
(or less) than the premium it paid for the original put option. The portfolio
will realize a gain if a call option it has written lapses unexercised, and a
loss if a put option it has purchased lapses unexercised.
 
FUTURES, OPTIONS ON FUTURES AND OPTIONS ON INDEXES
 
One risk of entering into financial futures contracts, buying options on such
contracts and buying options on financial indexes is that there may not be
enough buyers and sellers in the market to permit a portfolio to close a
position when it wants to do so. Then, besides continuing to be subject to the
margin requirements, the portfolio would have a gain or loss to the extent that
the price change in the securities subject to the hedge differed from the
position. To limit this risk, a portfolio will invest only where there is an
established secondary market.
 
A risk applicable to both futures contracts and related options is that changes
in the value of the contracts or option may not correlate with changes in the
underlying financial index or with changes in the value of the securities
subject to hedge or both. This failure may be partly due to temporary activity
of speculators in the futures markets. To the extent there is not a perfect
correlation, changes in the value of the portfolio's assets would not be offset
by a change in the value of the contracts and options it had bought.
 
When a portfolio buys an option on a futures contract or an option on a
financial index, its risk of loss is limited to the amount of the premium paid.
There is no such limit when a portfolio enters into a futures contract. However,
the loss on an options contract would exceed that of a futures contract if the
change in the value of the index is not more than the premium paid for the
option.
 
The success of a hedge depends upon the Adviser's or subadviser's ability to
predict increases or decreases in the relevant financial index. If this
expectation proves incorrect, the portfolio could suffer a loss and it would be
better off if those futures contracts or options had not been purchased. The
skills involved in determining whether to enter into
 
                                       28
<PAGE>   31
 
a futures contract or purchase or sell an option are different from those
involved in determining whether to buy or sell a security. The Adviser has had
only limited experience using financial futures contracts, options on financial
futures and options on financial indexes.
 
Because of the low margin deposits required, futures trading involves a high
degree of leverage. As a result, a relatively small price change in a futures
contract may result in an immediate big gain or loss. A purchase or sale of a
futures contract may result in losses in excess of the amount invested in the
futures contract. However, the portfolio would presumably have sustained
comparable losses if, instead of the futures contract, it had invested in the
underlying financial instrument.
 
Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price. Once the daily limit has been reached
in a particular type of contract, no more trades may be made on that day at a
price beyond that limit. The daily limit governs only price movements during a
particular trading day. It does not limit potential losses because the limit may
prevent the liquidation of unfavorable positions. Futures contract prices
sometimes move to the daily limit for several consecutive trading days with
little or no trading. When this happens, futures cannot be liquidated promptly
and some futures traders have big losses.
 
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. Buyers and sellers of foreign currency
options and futures contracts are subject to the same risks previously described
for options and futures generally.
 
A forward contract involves an obligation to purchase or sell a specific
currency at a future date. This may be any fixed number of days from the date of
the contract as agreed upon by the parties. The price is set at the time of the
contract. This way a portfolio may protect against a possible loss 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. These contracts tend to
minimize the risk of loss due to the decline in the value of the hedged
currency. On the other hand, they tend to limit potential gains if the value of
that currency increases.
 
When a forward contract's delivery date arrives, the portfolio may either
deliver of the foreign currency or end its 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
has to deliver the foreign currency, it may have to obtain the currency by
selling securities.
 
It is impossible to forecast the market value of portfolio securities at the
expiration of the forward contract. Therefore, the portfolio may have to buy
more foreign currency on the spot market (and bear the expense of that purchase)
if the market value of the security is less than the amount of foreign currency
the portfolio is obligated to deliver. Conversely, the portfolio may have to
sell some currency on the spot market when its hedged security is sold if the
security's market value exceeds the amount of foreign currency the portfolio is
obligated to deliver.
 
Settlement of currency options and futures contracts for most currencies must
occur at a bank in the issuing nation. The ability to establish and close out
positions on such options requires 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. The use of foreign currency hedging
transactions
 
                                       29
<PAGE>   32
 
might not successfully protect a portfolio against loss resulting from the
movements of foreign currency in relation to the U.S. dollar. These methods of
protecting the value of a portfolio's securities against a decline in the value
of a currency do not eliminate fluctuations in the underlying prices of the
securities. They simply establish a rate of exchange for a future time.
 
ZERO-COUPON AND PAY-IN-KIND DEBT SECURITIES
 
Zero-coupon securities (or "step-ups") in which a portfolio may invest are debt
obligations. They are generally issued at a discount and payable in full at
maturity. They generally 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. They
are subject to greater market value fluctuations from changing interest rates
than interest-paying debt obligations of comparable maturities which make
current distributions of interest. As a result, the net asset value of a
portfolio investing in zero-coupon and pay-in-kind securities may fluctuate more
than shares of other mutual funds investing in interest-paying securities with
similar maturities.
 
   
All of the portfolios other than the Money Market portfolio can invest in these
securities. The Capital Appreciation and High Income Bond portfolios may invest
more than 10% of their assets in these.
    
 
LOWER-RATED DEBT SECURITIES
 
   
Certain portfolios may purchase lower-rated debt securities, sometimes referred
to as "junk bonds." These are rated BB or lower by S&P or Fitch, or Ba or lower
by Moody's). As an example, the S&P lower bond ratings are described below.
Other ratings are in the Appendix to the Statement of Additional Information.
Only the High Income Bond portfolio now invests more than 35% of its assets in
junk bonds. The Capital Appreciation and Equity Income portfolios may invest
more than 10% of their assets in these securities.
    
 
When bonds have lower ratings it is more likely that adverse changes in the
issuer's financial condition and/or in general economic conditions, or an
unanticipated rise in interest rates, may impair the issuer's ability to pay the
bond's interest and principal. If an issuer cannot pay interest and principal on
time, it is likely to make the bond's values more volatile and it could limit
the portfolio's ability to sell its securities at prices approximating the
values that portfolio had placed on such securities. If there is no liquid
trading market for its securities, a portfolio may not be able to establish the
fair market value of such securities. The rating assigned to a security by
Moody's, S&P or Fitch does not necessarily reflect an assessment of the
volatility of the security's market value or liquidity.
 
Like those of other fixed-income securities, the values of lower-rated
securities fluctuate in response to changes in interest rates. Thus, a decrease
in interest rates generally will result in an increase in the value of a
portfolio's fixed-income securities. Conversely, during periods of rising
interest rates, the value of a portfolio's fixed-income securities generally
will decline. In addition, the values of such securities are also affected by
changes in general economic conditions and business conditions affecting the
specific industries of their issuers. Changes by recognized rating services in
their ratings of any fixed-income security and changes in the ability of an
issuer to pay interest and principal may also affect the value of these
investments. Changes in the value of portfolio securities generally will not
affect cash income derived from such securities, but will affect the portfolio's
net asset value. A portfolio will not necessarily dispose of a security when its
rating is reduced below its rating at the time of purchase. The Adviser or
subadviser will monitor the investment to determine if continuing to hold the
security will meet the portfolio's investment objective.
 
Issuers of lower-rated securities are often highly leveraged. During an economic
downturn or during sustained periods of rising interest rates, issuers may be
unable to service their debt obligations. In addition, such issuers may not have
more traditional methods of financing available to them, and may be unable to
repay debt at maturity by refinancing. The risk of loss due to default in
payment of interest or principal by such issuers is significantly greater
because such securities frequently are unsecured and subordinated to the prior
payment of senior indebtedness.
 
                                       30
<PAGE>   33
 
Sometimes lower-rated securities are issued to raise funds in connection with
the acquisition of a company in a "leveraged buy-out" transaction. The highly
leveraged capital structure of those issuers may make them especially vulnerable
to adverse changes in economic conditions.
 
   
Under adverse market or economic conditions or adverse changes in the issuer's
financial condition it may be harder for a portfolio to sell lower-rated
securities or the portfolio may have to sell the securities at a loss. In many
cases, such securities may be purchased in private placements. Then they are
subject to restrictions on resale as a matter of contract or under securities
laws. Then it may also be harder to determine the fair value of the securities
or to compute a portfolio's net asset value. In order to enforce its rights in
the event of a default, a portfolio may have to take possession of and manage
assets securing the issuer's obligations on such securities. This might increase
the portfolio's operating expenses and adversely affect the portfolio's net
asset value. A portfolio may also be unable to enforce its rights and it may
incur greater costs in enforcing its rights if an issuer enters bankruptcy.
Trading opportunities are more limited for low rated securities. This may make
it more difficult for a portfolio to sell or buy these securities at a favorable
price or time. This lack of liquidity also increases the risk of price
volatility.
    
 
A portfolio may hold securities that give the issuer the option to "call," or
redeem, its securities. If an issuer redeems securities held by a portfolio
during a time of declining interest rates, the portfolio may not be able to
reinvest the proceeds in securities providing the same investment return as the
securities redeemed.
 
S&P LOWER BOND RATINGS
 
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.
 
<TABLE>
<S>        <C>
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.
</TABLE>

The ratings from "BB" to "CCC" may be modified by adding a plus (+) or minus (-)
to show relative standing within the major rating categories.
 
REVERSE REPURCHASE AGREEMENTS
 
Under a reverse repurchase agreement, a portfolio sells a debt security to a
bank or broker-dealer. The portfolio agrees to repurchase it at an agreed upon
time and at an agreed upon price. The portfolio retains record ownership of the
security and the right to receive its interest and principal payments on the
security. At the agreed future date, the portfolio repurchases the security by
paying back the proceeds previously received, plus interest. The difference
between the amount the portfolio receives for the security and the amount it
pays on repurchase is deemed to be payment of interest. Until the portfolio pays
back the full amount, it maintains in a segregated custodial account assets with
a value equal to the amount of the commitment to repurchase, including interest.
In some agreements, there is no agreed-upon repurchase date and interest
payments are calculated daily. These are often based on the prevailing overnight
repurchase rate. The Securities and Exchange Commission views these transactions
as collateralized borrowings by the portfolio. The portfolios must abide by
their investment restrictions for borrowing money.
 
All of the portfolios other than the Money Market portfolio may invest in
reverse repurchase agreements. Only the International, International Small
Company, Capital Appreciation, Aggressive Growth, High Income Bond, Equity
Income, Blue Chip and Strategic Income portfolios may invest more than 10% of
their assets in reverse repurchase agreements.
 
LEVERAGING (BORROWING FOR INVESTMENT PURPOSES)
 
The Capital Appreciation, Aggressive Growth, Growth & Income, Strategic Income,
Small Cap Growth, High Income Bond, Equity Income and Blue Chip portfolios may
borrow for investment purposes. This is generally unsecured, except to the
extent the portfolios enter into reverse repurchase agreements. The Investment
Company Act of 1940 requires these portfolios to maintain continuous asset
coverage three times the amount borrowed. Asset coverage means total assets
including borrowings less liabilities exclusive of borrowings. If the asset
coverage declines as a result of market fluctuations or other reasons, a
portfolio may have to sell some of its holdings within three days to reduce the
debt and restore the asset coverage to the required three times. From an
investment standpoint, it may hurt the portfolio to sell securities then.
 
Borrowing may increase a portfolio's net income. However, it also adds risk. For
example it may exaggerate the effect on net asset value of any increase or
decrease in the market value of a portfolio's securities. To the extent the
income derived from securities purchased with borrowed funds exceeds the
interest a portfolio will have to pay, that portfolio's net income will be
greater than if it had not borrowed. Conversely, if the income from the assets
retained with borrowed funds does not cover the cost of borrowing, the net
income of that portfolio will be less than if borrowing were not used.
Therefore, the amount available for distribution as dividends will be reduced.
The portfolios also may have to maintain minimum average balances in connection
with borrowing or they may have to pay a commitment or other fee to maintain a
line of credit. Either of these requirements would increase the cost of
borrowing over the stated interest rate.
 
SECURITIES LENDING
 
A portfolio (other than the Money Market portfolio) may increase its total
return by lending its securities. It may do this if:
 
- - the loan is secured by collateral consisting of U.S. government securities,
  cash or cash equivalents adjusted daily to have market value at least equal to
  the current market value of the securities loaned;
 
- - the portfolio may at any time call the loan and regain the securities loaned;
 
- - the portfolio will receive any interest or dividend paid on the loaned
  securities; and
 
                                       32
<PAGE>   35
 
- - the aggregate market value of any securities loaned never exceeds one-third
  (or such other limit as the Board of Directors may establish) of the total
  assets of the portfolio.
 
The risks in lending portfolio securities include the possible delay in
recovering the securities or possible loss of rights in the collateral if the
borrower fails financially. Before a portfolio enters into a loan, the Adviser
or subadviser considers all relevant facts and circumstances. These include the
creditworthiness of the borrower. Voting rights on the loaned securities pass to
the borrower. However, the portfolio retains the right to call the loans at any
time on reasonable notice. The portfolio will do so if the holders of such
securities are asked to vote upon or consent to matters materially affecting the
investment.
 
SHORT SALES
 
The Aggressive Growth, Strategic Income, High Income Bond, Equity Income and
Blue Chip portfolios may engage in short sales. In these transactions, the
portfolio sells a security it does not own because the subadviser expects the
market value of that security to decline. To complete such a transaction, the
portfolio must borrow the security to make delivery to the buyer. The portfolio
then has to replace the borrowed security by purchasing it at the current market
price. The price may then be more or less than the price at which the portfolio
sold the security. Until the security is replaced, the portfolio has to pay the
lender amounts equal to any dividends or interest that accrue during the period
of the loan. The portfolio also may have to pay a premium to borrow the
security. This increases the cost of the security sold. The broker keeps the
proceeds of the short sale to the extent necessary to meet margin requirements
until the portfolio closes its short position.
 
The frequency of short sales that the portfolios engage in varies under
different market conditions. No securities will be sold short if, after effect
is given to that short sale, the total market value of all securities sold short
would exceed 25% of the value of a portfolio's net assets. This is a
nonfundamental operating policy and it may be changed without shareholder
approval. Portfolios may not sell short the securities of any single issuer
listed on a national securities exchange to the extent of more than 2% of the
value of the portfolio's net assets. Portfolios may not sell short more than 2%
of the outstanding securities of any class of an issuer.
 
A portfolio will incur a loss as a result of a short sale if the price of the
security increases between the date of the short sale and the date on which the
portfolio replaces the borrowed security. Conversely, a portfolio will realize a
gain if the security declines in price between those dates. This result is the
opposite of what you would expect from a cash purchase of a long position in a
security. The amount of any gain will be decreased, and the amount of any loss
increased, by the amount of any premium or amounts in lieu of interest a
portfolio may have to pay in a short sale.
 
WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS
 
These transactions are made to secure what is considered to be an advantageous
price or yield for a portfolio. There are no fees or other expenses, other than
normal transaction costs. However, the portfolio must set aside enough of its
liquid assets to pay for the securities to be purchased. These assets are marked
to market daily and are maintained until the transaction has been settled. No
portfolio will engage in when-issued and delayed delivery transactions to an
extent that the portfolio would have to set aside more than 20% of the total
value of its assets. The Money Market portfolio does not engage in these
transactions.
 
REAL ESTATE SECURITIES
 
Real estate investments generally represent a substantial portion of the
Strategic Income portfolio. The High Income Bond portfolio may also have
significant amounts of real estate investments. The real estate investments are
limited to securities secured by real estate or interests therein and securities
issued by companies that invest in real estate or interests therein. These
investments may have risks associated with direct ownership of real estate.
These risks include declines in the value of real estate, risks related to
general and local economic conditions and increases in interest rates.
 
                                       33
<PAGE>   36
 
Real estate investment trusts (REITs) are pooled investment vehicles that invest
primarily in income producing real estate, or real estate related loans or
interests. REITs are often not diversified. They are subject to the risk of
financing projects. They may also be subject to heavy cash flow dependency,
defaults by borrowers and self-liquidation. REIT's often depend upon the skills
of property managers.
 
REITs are generally classified as equity REITs, mortgage REITs, or hybrid REITs.
Equity REITs invest the majority of their assets directly in real property and
derive income primarily from the collection of rents. Equity REITs can also
realize capital value. Mortgage REITs invest the majority of their assets in
real estate mortgages and derive income from the collection of interest
payments. Hybrid REITs invest their assets in both real property and mortgages.
A REIT is not taxed on income distributed to owners if the REIT complies with
Internal Revenue Code requirements.
 
REITs may subject a portfolio to certain risks associated with the direct
ownership of real estate. These risks include:
 
- - possible declines in the value of real estate;
 
- - possible lack of availability of mortgage funds;
 
- - extended vacancies of properties;
 
- - risks related to general and local economic conditions;
 
- - overbuilding;
 
- - increases in competition, property taxes and operating expenses;
 
- - changes in zoning laws;
 
- - costs resulting from the clean-up of, and liability to third parties for
  damages resulting from, environmental problems;
 
- - casualty or condemnation losses;
 
- - uninsured damages from floods, earthquakes or other natural disasters;
 
- - limitations on and variations in rents; and
 
- - changes in interest rates.
 
Investing in REITs involves certain unique risks in addition to those risks
associated with investing in the real estate industry in general. Equity REITs
may be affected by changes in the value of the underlying property owned by the
REITs. Mortgage REITs may be affected by the quality of any credit extended or
changes in interest rates.
 
                                FUND MANAGEMENT
 
The Adviser is a wholly-owned subsidiary of ONLI. The Adviser uses ONLI's
investments personnel and administrative systems. It is located at One Financial
Way, Montgomery, Ohio 45242. It has served as the Fund's investment adviser
since May 1996. Before that, the Fund's investment adviser was O.N. Investment
Management Company, an indirect wholly-owned subsidiary of ONLI.
 
ONLI provides its investment personnel, systems and related services to the
Adviser at cost. This is done under a service agreement among ONLI, the Adviser
and the Fund. These services are paid for by the Adviser, not the Fund. The
Adviser provides portfolio management, investment advice and administrative
services to the Fund. This is done under an investment advisory agreement.

                     PURCHASE AND REDEMPTION OF FUND SHARES
 
Fund shares are offered only to separate accounts of ONLI and ONLAC in
connection with ONLI's variable annuities and ONLAC's variable life insurance.
You may select Fund portfolios as described in your variable contract
prospectus. The value of your variable benefits will vary with the investment
experience of the portfolios you select.
 
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.
 
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
enough trading in portfolio securities that the current net asset value of its
shares might be materially affected. The values are determined as of 4:00 p.m.
eastern time on each day the New York Stock Exchange is open for unrestricted
trading.
 
                       DIVIDENDS, DISTRIBUTIONS AND TAXES
 
Each portfolio seeks to qualify as a regulated investment company under
Subchapter M of the Internal Revenue Code. It is the Fund's policy to comply
with the provisions of the Code regarding distribution of investment income and
net realized capital gains so that the Fund will not be subject to federal
income tax on amounts distributed. Each year the Fund distributes to its
shareholders substantially all of its net investment income and net realized
capital gains (if any). For the Money Market portfolio, all of the undistributed
net investment income is determined and paid as a dividend immediately before
each daily computation of the portfolio's net asset value. For the other
portfolios, dividends representing net investment income are normally
distributed quarterly. Any net realized capital gains are distributed annually.
However, the Board of Directors may declare dividends at other times. Dividends
and distributions are automatically reinvested in additional portfolio shares
(at net asset value without a sales charge).

(a) This total return information does not reflect expenses that apply to any
    separate account or the related variable annuity or variable life insurance
    contracts. Including of those charges would reduce the total return figures
    for all periods shown.
 
(b) Annualized.
 
(c) On and after June 17, 1993, the investment adviser has waived part of the
    management fee with respect to the Money Market portfolio, to the extent
    such fee exceeds an annual rate of 0.25% of the Money Market portfolio's
    daily net asset value.
 
(d) The investment adviser reimbursed certain operating expenses of the
    International portfolio in 1993, the Capital Appreciation and Small Cap
    portfolios in 1994, and the Global Contrarian portfolio in 1995. Had the
    investment adviser not reimbursed such expenses, the annualized ratio of
    expenses to average net assets would have been 1.39% and the annualized
    ratio of net investment income to average net assets would have been 0.15%
    for the International portfolio in 1993. Had the investment adviser not
    reimbursed such expenses of the Capital Appreciation and Small Cap
    portfolios, the annualized ratio of expenses to average net assets would
    have been 1.05% and 0.95%, respectively in 1994. The annualized ratio of net
    investment income to average net assets would have been 3.18% and 3.24%,
    respectively, for the Capital Appreciation and Small Cap portfolios. Had the
    investment adviser not reimbursed such expenses of the Global Contrarian
    portfolio, the annualized ratio of expenses to average net assets would have
    been 1.90% and the annualized ratio of net investment income to average net
    assets would have been 1.32% for the Global Contrarian portfolio in 1995.

                                    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

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
Growth & Income Portfolio, the Relative Value Portfolio, the Emerging Growth

contracts issued by ONLI and ONLAC. In the future, Fund shares may be used for
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
Relative Value Portfolios in 1997, and the Small Cap Growth, High Income Bond,
Equity Income and Blue Chip Portfolios in 1998. The investments held by each
portfolio are maintained separately from those held by the other portfolios.

The investment and reinvestment of the assets of the Equity, Money Market, Bond,
Omni, S&P 500 Index and Social Awareness Portfolios is directed by the Fund's
investment adviser, Ohio National Investments, Inc. (the "Adviser"), a
wholly-owned subsidiary of ONLI. The principal business address of ONLI, ONLAC
and the Adviser is One Financial Way, Montgomery, Ohio 45242. The investment and
reinvestment of International and International Small Company Portfolio assets
is managed by Federated Global Investment Management Corp. ("FGIM") as
sub-adviser. The principal business address of FGIM is 175 Water Street, New
York, New York 10038. The investment and reinvestment of Capital Appreciation
Portfolio assets is managed by T. Rowe Price Associates, Inc. ("TRPA") as

sub-adviser. The principal business address of SCM is 100 Heritage Reserve,
Milwaukee, Wisconsin 53051. The investment and reinvestment of Core Growth
Portfolio assets is managed by Pilgrim Baxter & Associates, Ltd. ("PBA") as

Income and Blue Chip Portfolio assets is managed by Federated Investment
Counseling ("FIC") as sub-adviser. The principal business address of FIC is
Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, Pennsylvania 15222.

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>   57


                                 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:

In addition to average annual total returns, advertising may reflect cumulative
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
the portfolios from the inception of the portfolio and for the five- and
ten-year periods ending on December 31, 1998 (assuming a hypothetical initial
investment of $1,000) were as follows:

*Prior to January 1, 1999, the sub-adviser of the International and
International Small Company Portfolios was Societe Generale Asset Management

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>   59


      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 50% to 250%. 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.

      Small Cap 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.

<PAGE>   60

      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>   61



      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
Equity, 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 Equity, 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 Small Cap
              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 Small
              Cap Growth Portfolios may borrow money



                                       10
<PAGE>   62

              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;

              and options thereon within the limits of investment restriction 7
              below, and (b) the S&P 500 Index Portfolio may purchase or sell
              stock index futures contracts in accordance with its stated
              investment objectives;

      7.      other than the S&P 500 Index Portfolio, purchase or sell put or
              call options, except that each portfolio other than the Money
              Market Portfolio may, for hedging purposes, (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
              in options 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 contracts 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;

      8.      invest in securities of foreign issuers except that (a) each of
              the Equity, Bond, Omni, Core Growth, Growth & Income, S&P 500
              Index, Social Awareness and Relative Value Portfolios may (i)
              invest up to l5% of their respective assets in securities of
              foreign issuers (including foreign governments or political
              subdivisions, agencies or instrumentalities of foreign
              governments) American Depository Receipts, and securities of
              United States domestic issuers denominated in foreign currency,
              and (ii) invest up to an additional l0% of the assets of the
              portfolio in securities issued by foreign governments or political
              subdivisions, agencies or instrumentalities thereof, (b) each of
              the Small Cap and Small Cap Growth Portfolios may invest up to 30%
              of its assets in the securities of foreign issuers, (c) the Money
              Market Portfolio may invest up to 50% of its assets in the

              in selling portfolio securities;

      10.     purchase or sell real estate, except that each portfolio may
              invest in securities secured by real estate or interests therein
              or securities issued by companies which invest in real estate or
              interests therein. For purposes of this restriction, "real estate"
              does not include investments in readily marketable notes or other
              evidence of indebtedness secured by mortgages or deeds of trust
              relating to real property;

              into repurchase agreements. Other than the Strategic Income
              Portfolio, no more than 10% of a portfolio's total assets will be

              that the Growth & Income Portfolio may sell securities short and
              the Strategic Income Portfolio may sell securities short if (i) it
              owns, or has a right to acquire, an equal amount of those
              securities or (ii) if it does not own the securities, it has
              segregated an amount of its other assets equal to the lesser of
              the market value of the securities sold short or the amount
              required to acquire those securities (while in a short position,
              the Portfolio will retain the securities, rights or segregated
              assets);



                                       11
<PAGE>   63


      13.     as to the Equity, Money Market, Bond and Omni Portfolios,

              exercising control or management;

      14.     purchase securities of other investment companies, except in
              connection with a merger, consolidation or reorganization, or

              or Bond Portfolios of the securities of closed-end investment
              companies if after the purchase: (i) a portfolio does not own more
              than 3% of the total outstanding voting stock of the other
              investment company or (ii) the value of the securities of all
              investment companies held by such portfolio does not exceed 10% of
              the value of the total assets of that portfolio. Purchases of
              investment company securities will be made (a) only on the open
              market or through dealers or underwriters receiving the customary
              sales loads, or (b) as part of a merger, consolidation or plan of
              reorganization.

As a nonfundamental policy of each portfolio other than the Money Market,
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>   64

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 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.

Under normal market conditions, at least 65% of the assets of the International
and International Small Company Portfolios will be invested in securities of
issuers in at least three different foreign countries. As of the date of this
Statement of Additional Information, the Board of Directors has approved
investment by those portfolios other than the Money Market Portfolio in 60
countries with developed securities markets, including the following countries
with developed economies: Australia, Austria, Belgium, Canada, Denmark, Finland,
France, Germany, Ireland, Israel, Italy, Japan, Luxembourg, Netherlands, New

CAPITAL APPRECIATION PORTFOLIO FUNDAMENTAL POLICIES

As a matter of fundamental policy, the Portfolio may not:

      C.A.1.         Borrow money except that the Portfolio may (i) borrow for
                     non-leveraging, temporary or emergency purposes and (ii)
                     engage in reverse repurchase agreements and make other
                     investments or engage in other transactions, which may
                     involve a borrowing, in a manner consistent with the
                     Portfolio's investment objective and program, 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 liabilities (other than borrowings)
                     or such other percentage permitted by law. Any borrowings
                     which come to exceed this amount will be reduced in
                     accordance with applicable law. The Portfolio may borrow
                     from banks, other portfolios managed by TRPA or other
                     persons to the extent permitted by applicable law;

      C.A.2.         Purchase or sell physical commodities; except that it may
                     enter into futures contracts and options thereon;

      C.A.3.         Purchase the securities of any issuer if, as a result, more
                     than 25% of the value of the Portfolio's total assets would
                     be invested in the securities of issuers having their
                     principal business activities in the same industry;

      C.A.4.         Make loans, although the Portfolio may (i) lend portfolio
                     securities and participate in an interfund lending program
                     with other portfolios managed by TRPA provided that no such

                     the value of its total assets, more than 5% of the value of
                     the Portfolio's total assets would be invested in the
                     securities of a single issuer, except securities issued or

                     the outstanding voting securities of any issuer would be
                     held by the Fund (other than obligations issued or
                     guaranteed by the U.S. Government, its agencies or
                     instrumentalities);

      C.A.7.         Purchase or sell real estate unless acquired as a result of
                     ownership of securities or other instruments (but this

                     securities or other instruments backed by real estate or in
                     securities of companies engaged in the real estate

                     investment program.

      With respect to investment restrictions C.A.1. and C.A.4,, the Portfolio
      will not borrow from or lend to any other portfolios managed by TRPA
      unless they apply for and receive an exemptive order from the SEC or the

      promulgate any rules allowing the transactions.

      With respect to investment restriction C.A.2., the Portfolio does not
      consider currency contracts or hybrid investments to be commodities.

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

                     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.

                     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

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

         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>   72



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>   74


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, Small Cap Growth, High Income Bond, Equity Income and Blue Chip
Portfolios, by delegating that implementation to 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 Equity, 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;

daily net assets, 0.25% of the next $150 million, 0.23% of the next $250

over $1 billion;

Portfolios, 0.90% of each Portfolio's average daily net assets;

daily net assets, and 0.80% of average daily net assets over $150 million;

average daily net assets, and 0.80% of average daily net assets over $200

daily net assets, 0.35% of the next $150 million, and 0.33% of average daily net
assets over $250 million;

Adviser is presently waiving any of its fee in excess of 0.85%.

The Fund also incurs other miscellaneous expenses for legal and accounting
services, registration and filing fees, custodial services and shareholder
services.

International Small Company, Aggressive Growth, Core Growth, Growth & Income,
Strategic Income, Firstar Growth & Income, Relative Value, Small Cap Growth,

Portfolios' assets, subject to the supervision of the Adviser. As compensation

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 Equity, 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>   80


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>   82


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

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.

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>   86


      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>   87


      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>   88


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>   89


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.

 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.

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.
Neither the portfolio nor the index is open to direct investment.

 OBJECTIVE
 
The Omni Portfolio seeks a high level of long-term total rate of return
consistent with prudent investment risks. Total return consists of current
income and capital appreciation.
 
 PERFORMANCE AS OF DECEMBER 31, 1998
 
AVERAGE ANNUAL TOTAL RETURNS:

One-year                                    4.53%
Three-year                                 12.58%
Five-year                                  11.75%
Ten-year                                   11.50%
Since inception (9/10/84)                  11.50%
</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 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.

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.

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

 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.

 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>
 
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.

TOTAL RETURNS:
One-year                                      7.84%
Three-year                                    6.93%

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.

TOTAL RETURN:
 
<TABLE>
<S>                                          <C>
One-year                                      7.09%

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.

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.

SOCIAL AWARENESS PORTFOLIO
 
OHIO NATIONAL FUND, INC.
 
 OBJECTIVE
 
The objective of the Social Awareness Portfolio is to provide long-term growth
of capital by investing primarily in the common stocks and other equity
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.

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.

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.

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.

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.

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.

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.

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

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.

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
    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
   Standard & Poor's 500 Index or on narrow-based stock indexes. A particular
   index will be selected according to Ohio National Investments, Inc.'s
   ("ONI's"), the investment advisor to the Fund, investment strategy for the
   particular portfolio. The Fund may enter into such contracts to reduce the
   risk of fluctuation of portfolio securities values or to take advantage of
   expected market fluctuations.
 
   The S&P 500 Index Portfolio currently holds investments in S&P 500 Index
   Futures Contracts. The contracts in the S&P 500 Index Portfolio are fully
   hedged with commercial paper and/or US Treasuries. The Aggressive Growth
   Portfolio currently holds investments in Russell 2000 Index Futures Contracts
   and S&P 500 Index Future Contracts. The futures contracts in the S&P 500
   Index Portfolio and the Aggressive Growth Portfolio at December 31, 1998 are
   as follows:

   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

"corporate representative") of the Registrant (a Maryland corporation), except a
proceeding brought by or on behalf of the Registrant, the Registrant may
indemnify the corporate representative against expenses, including attorneys'
fees, and judgments, fines, penalties, and amounts paid in settlement, if such
expenses were actually and reasonably incurred by the corporate representative
in connection with the proceeding, if: (i) he or she acted in good faith; (ii)
in the case of conduct in his or her official capacity he or she reasonably
believed that his or her conduct was in the best interests of the Registrant,
and in all other cases he or she reasonably believed that his or her conduct was
