President's
Message
                                                            John J. Palmer Photo

Dear Investor:

First, I want to thank you for being an investor in the Ohio National Fund. All
of us here appreciate your support.
  We are pleased to provide you with an update of Ohio National Fund's
performance and investment activity for the six months ended June 30, 1999.

New portfolios

During the past six months, we have made adjustments in investment strategies to
expand the breadth and quality of managers and investment styles within our Ohio
National Fund portfolios. This focus on investment style choices and strong
professional investment managers means that we're working hard to provide even
better products and services for you.
  Noteworthy among those plans was the shareholder approval in late July for
Legg Mason Fund Adviser, Inc., to subadvise the $300 million Equity portfolio of
Ohio National Fund, Inc., effective August 2. This is the first agreement of
Legg Mason Fund Adviser, Inc., to subadvise a non-proprietary fund. The
portfolio manager, William H. Miller, III, CFA, is Morningstar's "1998 Domestic
Equity Fund Portfolio Manager of the Year." Morningstar's Manager of the Year
Award recognizes portfolio managers who demonstrate excellent investment skill,
the courage to differ from consensus and the commitment to shareholders
necessary to deliver outstanding long-term performance. Mr. Miller, president of
Legg Mason Fund Adviser, Inc., assumed overall responsibility for the equity
funds management area of Legg Mason in late 1990. He manages mutual funds,
including the flagship Legg Mason Value Trust.
  The Equity portfolio of Ohio National Fund, Inc., is now available in all of
Ohio National's variable annuity products, variable universal life products, and
pension plans.
In other subaccounts:

- - The Montgomery Small Cap Opportunities Fund has been replaced in our ONcore
  variable annuities by the Capital Growth (formerly Small Cap Growth) Portfolio
  of Ohio National Fund, Inc., which is managed by RS Investment Management
  (formerly Robertson Stephens Investment Management).

- - In January, Federated Investment Management Corp., began managing the
  International and International Small Company (formerly Global Contrarian)
  portfolios of the Ohio National Fund. They replace Societe Generale as the
  subadviser for the funds. Federated Investment Counseling (FIC) already
  manages the Blue Chip, Equity Income and High Income Bond portfolios of Ohio
  National Fund. Both are part of Pittsburgh-based Federated Investors, an
  investment manager founded in 1955 which now has more than $110 billion in
  managed assets.

  We already see steady gains in overall performance from these strategies. In
fact, four Ohio National Fund portfolios ranked in the top 50 equity funds
tracked by Lipper Analytics for performance during the month of June.
  To help our clients continue to pursue investment diversification, plans are
well underway to provide many more investment options with well-known money
managers for those in many of our existing variable universal life, variable
annuity and pension products in the fall 1999.

The importance of diversification

For all investors, it's important to continue to emphasize the value of
diversification. As a company, we certainly do not recommend investing solely in
the "style of the moment" or basing investment decisions strictly on market
timing. We remain dedicated to

                                        1
<PAGE>   2

staying in step with -- and in some cases, even ahead of -- other financial
service providers when it comes to improving our investment selections. We've
always kept a strong focus on providing our clients with diversified and
innovative portfolio choices, and we will continue this progress through 1999.

The market in general

We continue to enjoy an economic climate growing at a solid clip, low
unemployment, modest interest rates, subdued inflation and stable corporate
earnings.
  The second quarter of 1999 has proven to be just as interesting as the first.
April began with a strong price increase in the value of downtrodden cyclical
stocks as superior earnings were announced for these companies. Value investing
was back in style and money began to flow into the mid- and small-cap sectors of
the market.
  May proved to be relatively flat as investors began to worry about inflation
and the prospect of the Fed tightening the monetary supply. Small caps advanced
slightly, mid-caps were flat and large-caps were slightly down. NASDAQ stocks
did not have a good month and some internet IPOs actually held below the
stratosphere as investors' concern for real earnings began to show.
  During June, all of the major indices were up with the NASDAQ leading the way
at +11.4 percent, followed by DJIA up 6.2 percent, and the S&P 500 up 3.7
percent. The month also continued a broadening of the market as small- and
mid-cap stocks performed well versus the larger stocks.
  Looking into the future what can we expect based on the first six months of
the year? It seems clear that the volatility experienced in 1998 and the first
half of 1999 will continue for the rest of this year. Fears of higher interest
rates, renewed inflation and a potential downturn in the market are keeping
investors focused on every piece of news regarding their investments which in
turn leads to quick reactions every time there is either good or bad investment
news reported.
  It is equally clear that while investors are still enamored of the domestic
stock market, there seems to be a renewed interest in companies outside the
large-cap growth sector. Whether this signals a shift in market leadership is
too soon to tell, but it does bode well for the overall health of the domestic
stock market.

In Closing

Information on your investments is contained in the following pages. Please note
in reviewing performance results that rates of return under variable contracts
differ from those of the underlying portfolios because of applicable charges for
mortality and expense guarantees. Please contact your registered representative
for additional information on the financial protection and tax-deferred
accumulation options afforded by your variable annuity or variable universal
life insurance contract. As your needs change over time, he or she stands ready
to serve you.
  Thank you again for the confidence you have placed in Ohio National Fund as
you pursue your wealth-building endeavors. Be assured that we will make every
effort to continue to merit that confidence.

Best regards,

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 return for the Equity portfolio during the first half of 1999 was 9.3%. The
return for the portfolio was slightly negative during the first quarter as we
completed the transition from a multiple market capitalization portfolio (median
market capitalization of $2 billion) to a medium and large capitalization
portfolio with a median market capitalization between nine and ten billion. The
second quarter return was approximately 10%.

We expect the markets to remain somewhat volatile as concerns of rising interest
rates and inflation, and extended equity valuations help offset the continuing
strong earnings reported by many companies. Even though we expect the stock
market to incur periods of price corrections, we feel investing in the common
stocks of strong growing companies at reasonable prices will provide the best
returns on the financial markets.

BOND PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Bond Portfolio seeks to obtain a high level of income and opportunity for
capital appreciation consistent with preservation of capital.

 PERFORMANCE AS OF JUNE 30, 1999

AVERAGE ANNUAL TOTAL RETURNS:

<TABLE>
<S>                                     <C>
One-year                                    2.01%
Three-year                                  6.44%
Five-year                                   7.30%
Ten-year                                    7.51%
Since inception (11/2/82)                   8.20%
</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 Bond Portfolio returned 2.01% over the past year versus 4.19% for the Lehman
Government/Corporate Intermediate Bond Index. For the first six months of 1999,
the fund outperformed the Index -.32 to -.58. During the last six months of
1998, corporate bonds in the Baa category seriously underperformed Treasury
securities and the Index. The first half of 1999 has seen this situation turn
around somewhat and our performance has improved relative to the Index. The
economy is expected to slow somewhat in the second half of 1999 and interest
rates will likely be more stable than in the first half when the 30-year U.S.
Treasury bond yields increased approximately 1%.

OHIO NATIONAL FUND, INC.

 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 JUNE 30, 1999

AVERAGE ANNUAL TOTAL RETURNS:

<TABLE>
<S>                                        <C>
One-year                                    2.77%
Three-year                                 12.18%
Five-year                                  13.78%
Ten-year                                   11.09%
Since inception (9/10/84)                  11.53%
</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

The return for the Omni portfolio during the first half of 1999 was 6.01%. The
return for the portfolio was -0.49 during the first quarter as we completed the
transition of the common stock portion of the portfolio from a multiple market
capitalization portfolio (medium market capitalization of approximately $2
billion) to a medium and large capitalization portfolio with medium market
capitalization of approximately $10 billion. The second quarter return was
6.52%.

We expect the Equity market to remain somewhat volatile as concerns of rising
interest rates and inflation, and extended equity valuations offset the
continuing strong earnings reported by many companies. It is possible that
interest rates could continue to increase as inflation concerns mount and
commodity prices increase off their lows. We expect the stock market to incur
periods of price corrections and interest rates, though rising somewhat, to stay
within a reasonable range. We feel investing in the common stocks of strong,
growing companies at reasonable prices will provide the best returns in the
financial markets.

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 finally began to see investors focus again on emerging markets and Japan
after a notable period of under-
performance. This turnaround can be attributable to investor optimism that the
"Asian Crisis" is finally over. This rally however came at the expense of the
markets in Western Europe. Concerns over economic slowdown, a weak Euro
currency, and fund outflows were factors. The year-to-date performance ending
June 30, 1999 for the Ohio National International Portfolio stood at -1.01%.
This compared with 3.97% for the Morgan Stanley International Europe, Australia,
and Far East Index. The fund's underperformance was due to the timing in the
first half of 1999 in restructuring the fund. In the second-half of 1999 the
fund better matched our investment strategy. Our investment discipline is driven
by security selection where we are looking for well positioned companies with
strong bottom line growth that are trading at reasonable valuations. Moreover,
the fund was well positioned when the Japanese equity market began to rally.
Secondly, positions in the telecom and media sectors in Western Europe continued
to pay dividends. Finally, some of our top holdings include, Softbank, a leading
Japanese based software and media company and Nortel networks, a leading
provider of global high-capacity data networks for telephone and the internet.

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.

 OBJECTIVE

The Capital Appreciation Portfolio seeks maximum capital growth by investing
primarily in common stocks

 PERFORMANCE AS OF JUNE 30, 1999

AVERAGE ANNUAL TOTAL RETURNS:

<TABLE>
<S>                                          <C>
One-year                                      8.81%
Three-year                                   12.75%

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

Stocks made further progress in the second quarter, but bonds were weak. Stock
market participation broadened markedly, with large-cap cyclicals and small and
mid cap stocks supplanting large blue chip growth stocks as market leaders.
Technology stocks extended their gains, although the frenetic rally in Internet
stocks paused in April. The U.S. economy's continued resilience encouraged
investors to look beyond the handful of large growth stocks they had favored
when global growth prospects seemed more uncertain. Cyclical stocks reporting
sizable earnings increases did well, and income-oriented stocks revived. Natural
resources stocks continued to be buoyed by commodity price increases.

On the fixed income side, interest rates rose in the face of strong economic
growth and the Federal Reserve's announcement in May that it was biased toward
tightening. Investors immediately assumed that the Fed would raise short-term
rates at its June 30 meeting (which it did), but uncertainty about the size of
the increase and possible future increases weighed heavily on the fixed income
market. Treasuries and other high-quality bonds posted negative returns for the
quarter, and lower-quality (high-yield) bonds eked our positive returns only
because their high income offset modest price declines.

PERFORMANCE AND STRATEGY REVIEW

With our substantial exposure to basic industry, natural resources, and energy
stocks, the portfolio benefited from the change in stock market sentiment,
although our bond holdings were somewhat of a drag on results. The portfolio's
10.57% return was strong for the quarter, surpassing the broad market as
measured by the 7.05% S&P 500 Stock Index and the Lipper VA Underlying Capital
Appreciation Funds Average of 9.46%.

Reflecting trends in the overall market, several of our best contributors to
second quarter results were in the natural resources and energy areas. Our large
holding in MacMillan Bloedel, a Canadian forest products company, rose as
improving lumber prices and brightening prospects for global growth attracted
investor interest. Positions in Amerada Hess and other oil companies benefited
from oil price increases. Negative contributors included Tennessee Valley
Authority bonds, which suffered from rising interest rates. However, these bonds
fell much less than Treasury bonds of similar maturity because of their unique
features. Financial stocks were generally weak due to the rise in interest
rates.

There was no significant change in our asset allocation. Equity exposure
increased a bit to about 54%, convertibles were approximately 26%, and bonds
about 13%. Major purchases included securities of Roche Holdings (convertibles),
Unionsource Energy, and Niagara Mohawk Holdings. Major sales included Atlantic
Richfield, which is involved in a merger, and Rouse.

OUTLOOK

We remain cautious. The economy looks good, but market valuations
(price/earnings ratios, dividend yields) are expensive. We believe there is a
very strong risk of higher interest rates in coming months, which historically
have hurt the financial markets before slowing the real economy.

Nevertheless, we continue to invest more than half of the fund in common stocks
because: 1) we hope our expertise enables us to benefit from specific company
situations or swings in investor enthusiasm and 2) the American economy is
strong and constantly creating new investment opportunities. We expect also to
continue holding significant nonequity assets to reduce the portfolio's overall
risk and enable investors to benefit from the long-term advantages of common
stocks, but with less interim volatility.

SMALL CAP PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Small Cap Portfolio seeks maximum capital growth by investing primarily in
common stocks of small- and medium-size companies.

 PERFORMANCE AS OF JUNE 30, 1999

AVERAGE ANNUAL TOTAL RETURNS:

<TABLE>
<S>                                         <C>
One-year                                    41.97%
Three-year                                  18.03%
Since inception (4/30/94)                   23.96%
</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 quarter, investor's expectations of stronger economic growth led to
strong performance among cyclicals, such as energy and producer durable stocks.
We believe the shift toward cyclicals may be positive for small-cap issues in
general since small caps historically have tended to outperform during periods
of accelerating economic growth. The Ohio National Small Cap Portfolio benefited
from a broadening of the market, as interest shifted from large-cap stocks to
small companies.

As we evaluate current holdings in the Portfolio, we often identify particular
areas of strength within various business segments and end markets. Themes that
emerge out of this process allow us to leverage our cumulative research into new
ideas that can capitalize on the same attractive industry or market dynamics.

We continue to see strength in companies that are benefiting from what we call
the "enabling materials theme." In the continuous effort to improve performance
of electronic devices through faster, more powerful semiconductors, many
manufacturers are finding a need to produce devices on new material other than
the traditional silicon. We own a variety of companies that participate in this
trend.

Strong performers for the quarter include many of our holdings in the technology
sector. We saw extremely strong performance from holdings that fall into what we
refer to as the "rapid adoption of digital consumer electronics" theme.
Macrovision Corp. posted a quarterly return of more than 100%. Macrovision is
seeing strong demand for its copy protection solutions used to protect DVD's and
VHS cassettes.

Another strong performer within this theme was Zomax, Inc., the Portfolio's
largest holding. Zomax provides CD and DVD mastering and replication services,
and indicated within the quarter that earnings results would significantly
exceed expectations. Zomax returned more than 110% in the quarter.

The Portfolio recently initiated a position in Papa John's International
(0.96%). Papa John's is the fourth largest pizza chain in the U.S. with more
than 2,000 units, and we believe they have the potential to triple their current
base of units over the next several years. Attractive store economics, a
commitment to premium quality ingredients, and an increasing brand identity have
all contributed to create the most rapidly growing U.S. pizza chain.

differ significantly from the securities in the index. The index is unmanaged
and therefore does not reflect the cost of portfolio management or trading.

Returns represent past performance, which is no guarantee of future results.

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 MARKET

International small cap stocks have improved since the start of the year by
gaining 9.1% in the second quarter and 12.2% year-to-date, as measured by the
MSCI World, ex-US, Small Cap Index. Small cap markets were largely up, with
winners outnumbering losers two to one, reversing the trend observed in the
first quarter. The Asia/Pacific region continued to produce the highest
year-to-date returns (+29.4%) in the small cap world. By most signs now
available, Asian countries seem to have turned the corner toward recovery and
are rebuilding their economies through much-needed restructuring. The
introduction of the Euro in January fueled expectations that the new currency
would dominate global commerce. However, since then, the Euro has fallen
steadily. Technically, this makes Euro members' goods less expensive for
exportation. Surprisingly though, we have not seen a pickup in the Euro
countries' economies and export figures.

The Ohio National International Small Company Portfolio posted second quarter
gains of 25.3% and year-to-date gains of 24.3%. The gains produced in the second
quarter resulted from the extensive portfolio restructuring performed in the
first quarter of this year.

Global economies may have turned the corner sooner and faster than generally
expected, but generalizations must be avoided. Many countries continue to
improve, while others are just beginning to join the next economic wave. We
continue to follow our investment philosophy of investing in local consumption
stocks and secondary beneficiaries of global trade.

STRATEGY

- - Neutral weight in Europe

- - Overweight consumption stocks in Europe

- - Seek out Internet-related stocks and downstream beneficiaries

- - Underweight "Euroland" markets, particularly France, Germany and the
  Netherlands

- - Overweight Asia/Pacific, with strategic positions in Japan, Korea, Hong Kong
  and Singapore

- - Underweight Latin America

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.

AGGRESSIVE GROWTH PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The principal investment objective of the Aggressive Growth Portfolio is to seek
capital growth. The portfolio invests in a diversified collection of securities
believed to represent attractive growth opportunities.

 PERFORMANCE AS OF JUNE 30, 1999

TOTAL RETURNS:
One-year                                     (5.19)%
Three-year                                    5.72%

</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 market broadening finally arrived in the second quarter! The large-cap
growth stocks that had previously appeared untouchable finally took a breather.
Market leadership rotated dramatically to sectors that have languished for some
time such as industrial cyclicals and energy. In April, for example, industrial
cyclicals had their largest one-month gain in the last 50 years. This provided a
big gust of wind to sails of value managers and propelled the Russell 3000 Value
Index ahead of the Russell 3000 Growth Index for the first time in six quarters.

Market sentiment turned sour in May, as the consumer price report for April
showed that inflation grew at the fastest pace in nine years. Armed with
evidence of inflationary pressure, the Fed began applying the brakes by formally
adopting a directive towards raising short term interest rates. The angst
abided, as the May CPI number painted a much more benign inflationary picture
leading many to believe that the April number may have been an anomaly. The
quarter ended on a strong note with most investors believing that the Fed
action, which finally came on the last day of the quarter, was more akin to a
"flu shot".

Consistent with the performance of our benchmark, the Fund's performance
improved in the second quarter following a difficult first quarter. However, our
second quarter and year-to-date returns trail those of our benchmark. No single
issue explains our disappointing start in 1999. Rather, it is a culmination of
several factors. Our emphasis has been on dependable growth companies whose
returns have been consistent, yet trailed in an environment where, the more
speculative the investment, the better the performance has been. Retail was the
only sector that had a negative return for the quarter. Underweights in
semiconductor and telecommunication equipment hindered that Fund relative to its
benchmark, as those industries flourished in the second quarter. Investments in
securities that are undervalued but not yet recognized by the marker provide
good upward potential for the coming quarter.

The Fund is currently overweight in retail, capital equipment, and cyclical
stocks relative to the benchmark. Technology and financials have a slight
underweight, while energy and healthcare are in-line with the benchmark.

Our outlook for the general market is mixed. On the positive side, corporate
earnings are improving and our area of emphasis, small to mid-caps, is beginning
to perform much better. Offsetting this are, a higher interest rate environment
and high valuations for large company shares. Looking forward, we plan to
emphasize those sectors of the economy with the strongest growth outlook.
Examples include technology and financial services. We will also look to
capitalize on turning points in opportunistic industries, such as energy.

 COMMENTS

The Ohio National Fund Core Growth Portfolio returned 10.64% for the 2nd
quarter, 1999 and 21.59% for the six months ending June 30, 1999. This compares
with the Russell Mid Cap Growth Index returns of 10.42% and 14.19% respectively
for the same periods. Favorable sector weightings and stock selection are the
two major factors, which lead to the large outperformance. The Fund's most
heavily weighted sector, at nearly 40%, is technology. For the first half, this
sector has contributed well over half of the Fund's positive performance and
there has been broad strength among the holdings. Semiconductors,
telecommunication equipment, Internet services and contract manufacturing
companies all participated in this rally due to robust expectations for first
and second quarter earnings. The portfolio's representation in software is small
due to concerns over Year 2000 demand imbalances. The consumer cyclical sector,
which comprises mostly retailers, is the next largest contributor to Fund
performance in the first half. No one stock drove the overall performance, but
again, strength was broad among holdings. Health care and business services were
the only sectors to produce negative returns during the first half and their
effect was minimal.

U.S. economic outlook continues to be positive by most measures. The GDP report
for the first quarter of 1999 surprised everyone when it came in at a healthy
4.5%. At 4.3%, unemployment remains near a 30-year low. Despite the continued
tight labor market, wage inflation does not appear to be a significant threat,
according to the employment cost index. Productivity remains high. After a scare
in May, the CPI number release in June was zero. At its June 30th Open Market
Committee meeting, the Federal Reserve raised interest rates one-quarter point
and adopted "a directive that included no predilection about near-term policy
action".

Although large capitalization stocks have surpassed their smaller brethren
year-to-date, the second quarter provided an environment where small stocks beat
mid-size stocks which beat large caps. Growth stocks, other than having a tough
May, have led the market higher for the year across all capitalizations.

The business outlook for technology firms can change quickly. We believe that
investment managers need to be able to react quickly to, as well as anticipate,
the changing landscape of this sector. At no time is this more likely to be true
than in 1999, when Year 2000 issues will cause more opportunities and more
disappointments than in a typical year. The Fund will continue to be actively
managed and repositioned as the evidence unfolds.

We continue to like the long-term prospects of the all-cap growth companies we
own. Superior technologies, services, balance sheets, business models and
ability to execute are all characteristics commonly found in top quality growth
companies that we believe contribute to sustained, above-average growth rates.
Many investors have been anxiously waiting for the rebound in small/mid
capitalization stocks. We are encouraged with their recent outperformance and
there is much evidence to suggest their relative performance will continue to be
strong.

GROWTH & INCOME PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

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

 PERFORMANCE AS OF JUNE 30, 1999

TOTAL RETURN:

<TABLE>
<S>                                          <C>
One-year                                     22.83%
Since inception (1/3/97)                     25.92%
</TABLE>

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

 COMMENTS

The Ohio National Growth & Income portfolio produced positive returns in the
second quarter, increasing 14.86% versus a 10.86% increase in the Russell MidCap
benchmark and a 10.42% increase in the Russell MidCap Growth benchmark. For the
first six months of 1999, the portfolio increased 21.47% against a 10.34% rise
in the Russell Midcap benchmark and a 14.19 increase in the Russell Midcap
Growth index.

We benefited from a continued broadening of investor interest in mid and small
cap stocks. While most small and mid cap benchmarks increased at double digit
rates in the second quarter, the S&P 500 rose "only" 7.03%, a slowing of past
quarter's strong showing.

We continued our strategy of running the portfolio in a broadly diversified
manner. We maintained our strong weighting to technology, focusing on a range of
technology subsectors including telecom services, wireless, and semiconductors.
We also continue to mine the broad cable area, a sector our research process led
us to back in 1997 and 1998, ahead of many investors. We continue to realize
strong gains from a number of holdings in this sector as investors recognize the
return potential in companies involved in wiring the home for telephone, TV, and
internet communications.

Outside of overweighted exposure to technology, we maintained our commitment to
the energy services sector. Despite the volatility of many energy service
companies, we remain convinced this sector provides excellent long-term
potential.

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

 OBJECTIVE

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

 PERFORMANCE AS OF JUNE 30, 1999

<TABLE>
<S>                                         <C>
TOTAL RETURN:
One-year                                    23.98%
Since inception (1/3/97)                    30.07%
</TABLE>

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

 COMMENTS

1998 turned out to be a very volatile, but yet another good year for the S&P 500
Index and for your Ohio National S&P Fund. The Ohio National Index Fund mirrored
volatile ups and downs in the stock market, leading all index funds in return
most of the year. An accomplishment we are most proud of, your Ohio National
Index Fund won the 1998 Lipper Award for being the best performing index fund in
the country. The Ohio National fund finished the year with a total return after
expenses of 30.00%, or 1.42% higher than the actual index.

At June 30, 1999 your fund is still on track. After expenses, the Ohio National
fund is returning 12.38% for the first six months of the year, which exactly
equals the S&P 500 Index return. Per Lipper's published reports, this puts the
Ohio National fund as fourth best returning index fund on a year to date basis,
and as the best returning fund over the twelfth month period June 30, 1998
through June 30, 1999. Just as importantly, since inception (January 3, 1997)
the Ohio National Fund has tracked the S&P 500 Index returns on a monthly basis
with a correlation of 98.98% (with 100% being a perfect matching of the S&P 500
Index monthly ups and downs).

Looking ahead a bit to July 31, 1999 the Ohio National fund's year to date
return has dropped to 9.10%, after the S&P 500 Index dropped by more than 3.0%
during the month of July. However, as of July 31, 1999 the Ohio National fund
after expenses, is out performing the S&P 500 Index by 22 basis points, or is
returning year to date 9.10% versus 8.88% for the S&P 500 Index. This should put
the Ohio National Fund at or very near the top of all index funds in performance
year to date, and for the past twelve months.

We are currently experiencing the typical "summer doldrums" in the stock market,
with fear of rising interest rates fueling large drops in the index. However,
economic growth is good, and GDP growth will remain strong for 1999. Weak Asian
and South American economies have already begun rebounding. A few "Y2K" problems
at year end could send the markets materially, although temporarily lower.
Ultimately though, I expect to be discussing stock market gains with you nine to
twelve months from now.

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.

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.

 PERFORMANCE AS OF JUNE 30, 1999

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

The Social Awareness Fund has performed much better over the last six months,
particularly during the second quarter of 1999. During the last six months when
the S & P 500 Index was up approximately 12.4%, your fund was up 4.5%. However,
during the second quarter of 1999 when the S & P 500 Index was up approximately
7.1%, your fund was up 17.4%. The volatility that we expected in the stock
market over the last six months had a profound effect on the fund's performance
The portfolio exhibited greater volatility than the overall market due to a
larger weighting in smaller, value-oriented companies. Smaller companies didn't
offer any support during last year's market correction, even though their
valuations would have suggested otherwise. We hung onto these positions
throughout the market turbulence in anticipation of future returns. These
companies began to show improvement recently along with the capital goods,
cyclical and energy sectors.

As a result of the fund's volatility and disappointing returns, management of
the fund has taken steps to rectify the situation. The fund is now under new
management. We are confident that the management of the fund will better reflect
the fund's objective and its performance will more closely align with its peer
group. Under this new direction, the fund has a better focus on growth names and
larger companies with excellent prospects.

The fund will focus on sectors believed to offer the best potential for capital
appreciation. Those sectors currently include: communication services, consumer
staples, financials and technology. As always, the portfolio will only select
companies which have superior earnings potential with strong management teams
combined with a positive outlook.

Due to the recent strength of the stock market, valuation has become an even
greater concern with many securities. Your fund has participated greatly with
the recent market highs, tempered slightly by higher interest rates. We look for
sustained strong performance but we must contend with many issues that we will
continue to monitor over the next year. We are concerned with sustained earnings
growth, year-2000 issues and inflation fears. Regardless of these concerns, your
fund will stay fully invested, as we are not market-timers.

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

STRATEGIC INCOME PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

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

 PERFORMANCE AS OF JUNE 30, 1999

TOTAL RETURN:

<TABLE>
<S>                                         <C>
One-year                                    (2.29)%
Since inception (1/3/97)                     2.69%
</TABLE>

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

 COMMENTS

The Strategic Income Portfolio has maintained its unique, conservative approach
to producing high and stable levels of income through a difficult year. From
late 1998 through the first half of 1999 interest rates increased significantly.
The corresponding fall in bond prices is reflected in the negative total return
of this portfolio. Real Estate Investment Trusts (REITs) values increased in the
second quarter of 1999, and the portfolio's REIT holdings have helped it
generate solid performance relative to other bond funds while maintaining a high
dividend yield. Mortgage-backed securities have been among the best performing
securities in the portfolio over the past year.

We believe bond yields are near their peak for 1999. We still advocate an
overweight position in corporate fixed-income and mortgage-backed securities.
Mortgage-related bonds performed well in the first half of 1999. While we
believe this sector will complete the year with top performance, we have been
reducing risk exposure by moving into lower coupon bonds which will perform
better should interest rates decline.

FIRSTAR GROWTH & INCOME (a)
OHIO NATIONAL FUND, INC.

 OBJECTIVE

The Firstar Growth & Income seeks to provide both reasonable income and
long-term capital appreciation by investing in income producing securities,
including dividend paying common and preferred stock as well as fixed income
securities.

 PERFORMANCE AS OF JUNE 30, 1999

TOTAL RETURN:

<TABLE>
<S>                                         <C>
One-year                                     3.71%
Since inception (1/3/97)                     6.40%
</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 Growth and Income Portfolio invests exclusively in high quality companies
that must pay a dividend. This results in a portfolio which has a lower
allocation to technology companies than what is found within the Standard &
Poor's 500 stock index, as most of these companies pay little or no dividend.
Technology has been driving performance during the first seven months of 1999,
making the portfolio's small investment in that area a drag on relative
performance. Specifically, the technology sector is the largest area of the S&P
500, and has returned 24% during the first seven months of 1999. During periods
of speculation such as the current internet mania, the Growth and Income
Portfolio will typically lag in relative performance. The goal of the portfolio
is not to capture all the return in such periods, but to ?lose less? when the
market weakens. Historically, the dividend requirement has helped the portfolio
achieve favorable performance with a lower level of return volatility.

Our view on the current market environment is one of caution. The steep rise in
interest rates in 1999 has made bonds very attractive compared to stocks. The
technology stocks referenced above routinely trade at more that 50 times
expected earnings, making them vulnerable to a market decline. The Growth and
Income Portfolio has large investments in the consumer cyclical, health care,
and financial areas. These holdings are trading at reasonable valuations and
have strong earnings growth prospects for the year 2000. Our research efforts
are also focused on those companies not among the very largest. The most
expensive area of the market is in the largest companies, providing outstanding
opportunities in the smallest 450 companies within the S&P 500.

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 JUNE 30, 1999

<TABLE>
<S>                                         <C>
TOTAL RETURN:
One-year                                    19.52%
Since inception (1/3/97)                    23.60%
</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

For the past two years, "value" investing has been out of favor. We believe that
recent strength in cyclical stocks and the energy sector are indicators that
"value" stocks may be returning to favor. The favorable interest rate
environment we expect for the remainder of this year would allow a continued
emphasis on financial issues which are normally "value" stocks. For the twelve
months ending May 31, 1999 the Relative Value Portfolio produced a rate of
return in excess of 15% on a net asset value basis. This exceeded the return for
the average growth and income fund as reported by Lipper Analytical Services
Inc., 11.4%, by over 400 basis points.

Our outlook for the remainder 1999 anticipates the pace of domestic economic
growth to slow towards a more moderate level. We expect inflation will remain
under 2.5% for the year, as commodity prices are signaling little inflationary
pressure, and the dollar remains strong. These factors should be positive for
stocks. Relative Value's diversified portfolio of high quality, large cap stocks
should perform well, as the diversification helps reduce the risk caused by any
potential market rotations.

securities of high quality companies.

 PERFORMANCE AS OF JUNE 30, 1999

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 six month period ended June 30th was a strong continuation of the bull
market with the S&P 500 returning 12.39%. The period started as 1998 had
finished: strong market returns during the first quarter were provided by a
handful of large capitalization growth stocks. However, things shifted
dramatically in April. Sparked by surprisingly strong first quarter earnings, a
revival in oil prices and signs of a global economic recovery, market leadership
rotated to a broader group of cyclical, commodity and smaller capitalization
stocks. After three years of returns being dominated by a limited list of large
capitalization growth stocks, the perceived revival of global economic activity
benefited areas of the market which had not been the "safe havens" from the
global economic turmoil of the past two years and whose earnings should benefit
with a marked increase in global growth. Due to this dramatic improvement in
market breadth, the second quarter provided the average active equity manager
the best performance relative to the S&P 500 in quite some time.

Your fund provided a return of 11.77% for the six-month period, underperforming
the S&P 500 but outperforming the Lipper Growth & Income fund, which returned
10.93%. Aiding relative performance for the six-month period was favorable
security performance in the Health Care, Capital Goods and Consumer Cyclicals
sectors. Detracting from relative performance were underweight positions in the
strong performing Technology and Communication Services sectors, as well as
unfavorable security performance in the Basic Materials sector.

Our stock market outlook remains basically unchanged -- the market appears
overvalued by all traditional measures, but no visible catalyst is positioned to
change this. Relative to interest rates, the markets are extremely overvalued.
Real interest rates are extremely high as the bond market believes that
inflation is around the corner. However, the equity markets, fueled by the Fed's
late June neutral stance towards monetary policy, believe that technology and
continued growth in productivity will keep inflation at bay. We believe that the
valuation disparities between ultra-large growth stocks and the rest of the
market, combined with a strong near-term earnings outlook, can fuel a
continuation of the market's rotation towards a broader array of value and
smaller capitalization stocks.

EQUITY INCOME PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

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

 PERFORMANCE AS OF JUNE 30, 1999

TOTAL RETURN:
One Year                                    15.51%

</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 stock market in the second quarter was marked by dramatic reversals in
leadership based on market capitalization, investment style (i.e., value versus
growth), and sector. Through March, the largest companies in the S&P 500
dominated. In the second quarter, small capitalization stocks outperformed large
capitalization stocks by 8.5%, as reported by Ned Davis Research. There was also
a sudden reversal in investment style. Since the fourth quarter of 1997, growth
stocks had provided excess return relative to value stocks. Ned Davis also
reports that in this most recent quarter, large capitalization value stocks
outperformed large capitalization growth stocks by 7.5%. These shifts were
accompanied by rapid sector rotation, as technology, financial and
pharmaceutical groups lagged while the beleaguered basic materials and
industrial cyclical sectors surged.

The broadening in what had been until recently a narrow market was due to the
increasing perception that overseas economies were improving, while the United
States economy continued to be robust. This strength caused concern in the bond
market, where the 30-year Treasury bond yield rose from its October 1998 low of
4.7% to over 6.0% by the end of June 1999 in what was the largest percentage
move upward in yields during the low-inflation decade of the 1990s. Therefore,
when the Federal Reserve raised short term interest rates by 0.25% in late June,
the first increase since March 1997, the markets were much more focused on the
Federal Reserve's stated inclination not to raise rates further, having well
anticipated the June rate hike.

For the quarter, the S&P 500 returned 7.05%. Your Ohio National Equity Income
Fund returned 7.64%, lagging the 9.23% return of the average equity income fund,
as reported by Lipper Analytical Services. However, on a year-to-date basis, the
Fund's total return of 10.41% is still nicely ahead of the 8.98% return of the
average equity income fund.

Stock market returns for the balance of the year will depend on positive
earnings growth and a benign interest rate environment. With regard to earnings
prospects, economic improvement in Asia has begun to benefit technology,
chemical and manufacturing companies. The economic expansion in the United
States is now 100 months old, making it the longest peacetime cycle. Still,
inflation is not evident. On the cost side, productivity improvements have
allowed our economy to grow without inflation. Meanwhile, on the revenue side,
intense global competition has made it difficult for companies to raise prices.
This low inflation, coupled with increasing evidence of a slowdown in our
economy's growth, would likely prevent the Federal Reserve from further rate
increases. Such an environment would be bullish for stocks.

Current Strategy:

Whether value stocks will retain their leadership as compared to growth stocks
will depend on improving earnings in the value-oriented sectors. In the case of
the Basic Materials sector there are good signs in the paper products and
chemicals groups, but still poor conditions for iron and steel, metals mining
and gold companies. Leadership could shift back to growth just as quickly as it
shifted away during this past quarter. Your Fund attempts to smooth this
volatility by seeking superior equity and convertible securities on a
sector-neutral basis. Your Fund holds a blend of growth and value securities
with a middle-to-large capitalization bias. We will continue to seek common
stocks of market-leading companies that have a long history of growing
dividends. We will also maintain a healthy component of higher-yielding
convertible bonds and preferred stocks, for their income and for their
relatively defensive attributes in market downturns.

HIGH INCOME PORTFOLIO
OHIO NATIONAL FUND, INC.

 OBJECTIVE

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

 PERFORMANCE AS OF JUNE 30, 1999

TOTAL RETURNS:

Since inception (5/1/98)                     1.78%
</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

High yield bonds delivered excellent relative returns for the six months ending
June 30, 1999. These returns were driven by continued strong domestic economic
growth which resulted in narrower yield spreads between high yield bonds and
Treasuries. The basic material sectors were standouts while healthcare was a
noticeable laggard. Credit risk was rewarded as CCCs outperformed BBs and Bs.
For the period, the Lehman Brothers High Yield Bond Index returned 2.20% versus
- -1.37% for the Lehman Brothers Aggregate Bond Index.

The fund outperformed the index (adjusted for expenses). On the positive side,
the fund was overweight the telecommunication sector, which outperformed, and
underweight healthcare. Specific holdings in Fox/Liberty, Metronet, Triton PCS,
Telesystems International and Teligent outperformed. On the negative side, the
fund was underweight the basic material sectors. Also, positions in KCS Energy,
Paging Network and Stena Lines underperformed because of disappointing financial
performance.

For the balance of 1999, we believe high yield bonds offer attractive relative
returns, given the strong domestic economic outlook. From a portfolio
perspective, we continue to be overweight the telecommunications sector given
the powerful secular growth characteristics of the sector. We remain biased to
modestly decreasing interest rate risk and increasing credit risk, given the
strong economic conditions.

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 JUNE 30, 1999

TOTAL RETURN:
One-Year                                    89.82%
Since inception (5/1/98)                    77.80%
</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

We enjoyed another strong quarter of investment performance in the second
quarter. The Ohio National Small Cap Growth portfolio increased 21.09% against a
14.75% increase in the benchmark Russell 2000 Growth. At the mid year point, the
portfolio is up 78.22% versus an increase of 12.82% in the Russell 2000 Growth.

Small Cap stock performance improved in the second quarter as investors returned
to small and midcap stocks. The small stock Russell 2000 benchmark return
exceeded the larger cap S&P 500 Composite by nearly 8% in the second quarter
while the Russell midcap benchmark exceeded the S&P 500 by some 4%. We view this
advance in small and midcap stocks as a positive sign that investors may be
starting to broaden their equity interest beyond a handful of large growth
stocks.

Strong interest in small cap stocks led to broad advances in many small cap
sectors. However, we continue to see keen interest in fast growing, high P/E
multiple stocks. We sliced the benchmark Russell 2000 Growth into five market
cap bands and looked at absolute returns of the stocks that fell into those
bands.

- - The Russell 2000 Growth market band that includes companies with market caps
  between $1 billion -- $5 billion includes 486 stocks and constitutes over 37%
  of the benchmark as of June 30, 1999. This marketcap band produced a return of
  19.94% through the first two quarters of 1999.

- - The market cap band that includes 412 companies with market caps between $500
  million -- $1 billion and constitutes more than 31% of the benchmark produced
  a return of 7.56% in 1999.

- - Similar trends develop when slicing the benchmark based on growth
  characteristics. We found many stocks with the fastest growth rates and
  highest P/Es (or no earnings) have outperformed the broad benchmark returns.

Thus the marketplace seems most interested in the fast growing companies on
which we traditionally focus. Within this universe, the market seems interested
in larger companies in certain sectors, bidding up both stock price and market
cap of a short list of names. Fortunately, we have been well positioned and
realized gains from a number of companies in technology, telecom, and other
emerging growth sectors.

We have also been very active in the IPO market in 1999. While Spring is
typically an active IPO season, the IPO flow, particularly in technology and
internet companies has continued at a very strong pace through the summer. We
continue to devote significant research energy to the IPO front, and have
participated in many new issues for the portfolio. The large number of IPOs in
the portfolio, is typically a source of supply, not performance, in the
investment process. Ultimately we look for some of these IPO companies to become
key holdings for us into the future.

We are pleased to achieve such powerful results and caution that while we are
optimistic looking forward, we don't expect returns like these to continue over
time.

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:

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

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

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

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

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

   - 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.

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

   - International Small Company Portfolio -- long-term growth of capital by

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

   - 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.

   - 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.

   - 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.

   - 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.

   - Firstar Growth and Income Portfolio -- reasonable income and long-term
     capital appreciation by investing in income producing securities including
     dividend-paying common, preferred stocks and fixed-income securities.

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

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

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

   - 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,
   International Small Company, Aggressive Growth, Firstar Growth & Income, 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 and S&P 500 Index
   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 S&P 500 Index Future Contracts. The
   futures contracts in the S&P 500 Index Portfolio and the Aggressive Growth
   Portfolio at June 30, 1999 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, International Small Company,
   Aggressive Growth, Firstar Growth & Income, 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, International Small
   Company, Aggressive Growth, Firstar Growth & Income, 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.

   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, International Small Company, Aggressive Growth, Core Growth and Small
   Cap Growth Portfolios: accumulated net investment loss has been decreased by
   $262,118, $19,704, $8,190, $55,275 and $15,183 respectively, resulting in a
   reclassification adjustment to decrease Paid-in capital in excess of par
   value by $262,118, $19,704, $8,190, $55,275 and $15,183 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 June 30, 1999. 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.

   portfolio as of June 30, 1999 were as follows:
