PRESIDENT'S MESSAGE

DEAR INVESTORS:
We are Pleased to provide you with an update of Ohio National Fund's 
performance  and investment activity for 1997. It was a very active and exciting
year, highlighted by the addition of several new portfolios and continued 
strong growth in net assets, which now total more than $911 million as of 
December 31.

LOOKING BACK
Against an economic backdrop of modest growth, low unemployment, and meager
inflation, U.S. stocks posted healthy gains for the third straight year, with
large stocks again leading the way. Nearly all of that performance came in the 
first seven months, however, and the year was marked by heightened market 
volatility. Internationally, stock market gains were generally respectable in
Europe, mixed in the Americans and dismal throughout the Asia/ Pacific region.
Fixed-income markets fared well as falling inflation and a stronger dollar
helped bonds bounce back in 1997 after posting weak returns during the previous
year.

NEW PORTFOLIOS
We welcomed seven new portfolios and three respected investment managers to Ohio
National Fund on January 3, 1997. Besides the S&P 500 Index and Social Awareness
portfolios, both managed by Ohio National Investments, Inc., they included the 
Growth & Income Portfolio, managed by Robertson Stephens; the Core Growth 
Portfolio, managed by Pilgrim Baxter & Associates; and the Relative Value, 
Stellar and Strategic Income portfolios, all managed by Star Bank. The addition 
of these portfolios significantly broaden the Fund's investment spectrum and 
offers greater opportunities for diversification for our investors. Please note 
that portfolio availability varies by contract.

LOOKING AHEAD
Entering 1998, Asia's turmoil continues to cloud the future. Economic and
currency volatility has hit Asian stocks hard and cast uncertainty over growth
prospects in the U.S. and elsewhere. In addition, the unprecedented three
consecutive years of greater than 20 percent returns experienced from 1995 to
1997 has put the domestic stock market in uncharted territory. But while the
short-term course of events is unknowable, our long-term commitment to our
fundamental investment principles -- careful selection and constant professional
management -- remains unchanged.

IN CLOSING
Information on your investments is contained in the following pages. We are 
proud that Ohio National Fund is able to provide its investors with the sound 
results documented herein. Please note in reviewing performance results that
rates of return under variable contracts differ depending on applicable charges
for mortality and expenses. 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 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,
/s/ John J. Palmer

OBJECTIVE

The principal investment objective of the Equity Portfolio is long-term capital
growth. Current income is a secondary objective.

PERFORMANCE AS OF DECEMBER 31, 1997 

AVERAGE ANNUAL TOTAL RETURNS:
One-year                                  18.17%
Three-year                                21.17%
Five-year                                 15.26%
Ten-year                                  13.61%
Since inception (1/14/71)                 11.07%

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

COMMENTS

The Equity Portfolio's performance for 1997 trailed that of the S&P 500 Index
for three primary reasons. First, the portfolio has maintained a 10% to 13% cash
position due to our concern with high stock prices (especially for large-cap
stocks) relative to expected earnings and growth. Second, even though our
largest holdings are mostly large-cap stocks, approximately two-thirds of the
portfolio's holdings consist of companies whose market capitalizations range
from $300 million to $5 billion. This area of the market has not kept pace with
the larger stocks, despite better valuations in relation to potential earnings
growth. Third, the portfolio didn't rebound from the October drop experienced by
nearly all equity markets. Although the S&P 500 Index recaptured most of its
earlier gains by year-end, a third of New York Stock Exchange issues and half of
Nasdaq Composite issues corrected 20% or more from their highs and did not
regain them. Areas that held back portfolio performance this period included
technology and energy. We expect these areas to rebound from their corrections
as their secular outlooks remain positive.

   Looking forward, we expect continued volatility in the equity markets.
Continued strong cash flows into mutual funds could push markets higher.
Concerns about slowing profit growth and economic uncertainty in emerging growth
areas and its impact on the rest of the world could cause sharp sell-offs. We
expect equity returns to gravitate toward their long-term averages.

</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 9.28% in 1997 versus 7.87% for the Lehman Brothers
Government/Corporate Intermediate Bond Index. The portfolio has a slightly
longer maturity structure than the index and benefited from the overall decline
in interest rates during 1997.

The portfolio should perform in line with the index during 1998 if we are
correct in forecasting less volatility in interest rates than was the case in
1997. Remember that past performance is not necessarily predictive of future
results.

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.

OMNI PORTFOLIO
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 DECEMBER 31, 1997

AVERAGE ANNUAL TOTAL RETURNS:
One-year                                  18.15%
Three-year                                18.78%
Five-year                                 13.47%
Ten-year                                  12.57%
Since inception (9/10/84)                 12.05%

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's performance for 1997 trailed that of the S&P 500 Index for
three primary reasons. First, the portfolio's investments consist of common
stocks and their equivalent, corporate and Treasury bonds and cash. This
portfolio structure will not outperform the S&P 500 Index in a strong
large-cap-led stock market. Second, the common stock portion of the portfolio
(approximately 65%) consists of small-, medium- and large-capitalization stocks.
Small- and mid-sized equities have generally not kept pace with the larger
companies. Finally, the cash position of the portfolio (approximately 17%) both
helped and hurt its performance during the fourth quarter of the year. It
cushioned the effects of the stock market correction, but also didn't
participate in the year-end stock bounce or the bond rally during the quarter.
   Looking forward, we expect continued volatility in the equity markets.
Continued strong cash flows into mutual funds could push markets higher.
Concerns about slowing profit growth and economic uncertainty in emerging growth
areas and its impact on the rest of the world could cause sharp sell-offs. We
expect equity returns to gravitate toward their long-term averages. Fixed-income
instruments should continue to provide steady results.

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.

INTERNATIONAL PORTFOLIO
OHIO NATIONAL FUND, INC.

OBJECTIVE

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


PERFORMANCE AS OF DECEMBER 31, 1997

AVERAGE ANNUAL TOTAL RETURNS:
One-year                                   2.11%
Three-year                                 9.43%
Since inception (5/3/93)                  13.03%

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

Over the 12 months ended December 31, 1997, the International Portfolio slightly
outperformed the MSCI EAFE Index while generating disappointing returns in a
year characterized by major turmoil in Asia and highly volatile world markets.
     While European holdings (approximately 37% of net assets at year-end) rose
along with local markets, the portfolio is overweighted in small capitalization
stocks which lagged major indices. The strength of the US dollar also lowered
returns, despite partial hedges in place throughout the year. In Asia, stocks
fell sharply in the wake of the severe crisis that developed in Southeast Asia
over the summer. Japanese equities (about 18% of net assets) were extremely poor
performers, particularly in the case of small capitalization stocks. A much
weaker yen further compounded the effect of sharply lower stock prices. Direct
Southeast Asian exposure was limited to less than 4% of net assets, but sharp
losses were registered in those markets. Finally, holdings in other emerging
markets were also negatively impacted by the consequences of the financial
crisis. Throughout the year, the portfolio maintained a defensive posture with
large cash holdings and assets diversified across many different countries.

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.

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

AVERAGE ANNUAL TOTAL RETURNS:
One-year                                  15.19%
Three-year                                17.80%

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 Capital Appreciation Portfolio advanced strongly in 1997, but its cautious
strategy could not keep up with the broad market. During the year's few periods
of market difficulty, however, the performance was outstanding.

Media stocks continued as a stellar area of investment, with both New York Times
and Washington Post being important contributors to performance. They remain
large holdings, although we have substantially reduced the Times position. We
also trimmed two of our big winners, Automatic Data Processing convertible bonds
and FirstEnergy. Our biggest disappointments were the plummeting gold mining
stocks. An unusual fixed-income purchase - putable Tennessee Valley Authority
bonds - is now one of our top five holdings. In return for their favorable
risk/return characteristics we give up a portion of current income - a
reasonable tradeoff given the uncertainty and potential magnitude of possible
future interest rate changes.

While the economy still looks fine, corporate earnings growth in 1998 is
unlikely to match of 1997. We consider valuation to be the most significant
negative facing the stock market, just as it was 12 months ago. Historic
yardsticks like price/earnings ratios and dividend yields are off the charts,
and we are skeptical of the underlying accounting.

vary. All returns reflect reinvested dividends. The portfolio's holdings may
differ significantly from the securities in the index. The index is unmanaged

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 second half of 1997 continued the trend of volatility set in the first half.
The third quarter was strong but followed by a weak fourth quarter, primarily
due to concerns over the Asian crisis and its effects on corporate profit
growth. The positives of 1997 were better than expected profits and a declining
inflation rate which led to lower interest rates. Unfortunately, the concern
over global growth resulted in investors favoring large cap investments.

We would expect 1998 to be more of the same at this point. The economies of
Europe and the Americas are healthy albeit growing slowly. Interest rates
continue to trend down as does inflation which is a good environment for
financial assets. The primary concern is the Asian crisis which will have a
deflationary effect and cause some slowdown in global growth. The uncertainty
over the magnitude of the Asian crisis and its impact will likely lead to
continued volatility across all global stock markets. We believe however that
the US is in particularly good shape with declining interest rates and a good
global competitive position. Small company stocks are at very attractive
valuations and with their higher growth rates should perform well in the current
environment.

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.

</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

Over the 12 months ended December 31, 1997, the Global Contrarian Portfolio
underperformed the MSCI World Index. This was due to several factors. First, a
fairly substantial percentage (approximately 17%) of net assets is invested in
various commodity-related securities (i.e., gold, forest products, base metals,
sugar) which declined markedly while the Asian crisis unfolded. Second, most
non-Asian world markets performed well in the first half of the year, but
displayed considerable volatility in the second half. While large capitalization
stocks recovered, small capitalization stocks lagged major indices. Because the
portfolio tends to be overweighted in smaller stocks, this hurt relative returns
for our US as well as foreign holdings. Third, the portfolio held a fairly large
cash position throughout the year (approximately 23% of net assets) which earned
meager returns in a low interest rate environment.

The portfolio has reduced its exposure to commodities-related securities over
the last six months as weaker global economic growth is anticipated in the
near-term following the Asian crisis. Simultaneously, the portfolio has started
cautiously buying stocks and bonds on a selective basis in a few Asian
countries. There is value to be found in certain depressed situations following
recent price collapses in that region.

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.

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

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


 Comments 

The US stock market finished the year much in the same way it began - with a
liquidity-driven rally in the large-cap, blue chip companies. We maintained our
focus on smaller growth companies, while the market experienced a "flight to
quality," mainly in large-cap and interest-sensitive issues. Our emphasis on
growth companies kept the portfolio underweighted in two outperforming sectors,
banks and utilities. In addition, a key holding, Danka Business Systems, lost
more than half of its market value with the release of unexpected disappointing
news in the fourth quarter.

Several years of utopian market conditions have been disrupted by Asian
financial crises, including severe currency devaluations necessitating IMF
bailouts. These events have raised prospects of worldwide over-capacity, price
cuts, diminished US exports and generally reduced economic growth and corporate
profits. Moreover, recent market volatility may dampen investor enthusiasm for
stocks in general.

In this environment we believe dependable growth companies will attract premium
valuations. The portfolio already emphasizes such companies, and we will
continue to upgrade our holdings with this focus in mind. Our strategy is to
proceed cautiously. Although the current environment is less certain than the
past, we believe there are ample opportunities to invest in companies that can
achieve attractive results.

CORE GROWTH PORTFOLIO
OHIO NATIONAL FUND, INC.

 Objective

The objective of the Core Growth Portfolio is to provide long-term capital
appreciation.


 Performance as of December 31, 1997

AVERAGE ANNUAL TOTAL RETURN:
<S>                                       <C>
Since inception (1/3/97)                  -3.08%
</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 top 30 companies in the Russell 3000 Growth Index represent 47% of the
index's market capitalization. While they are growing at above-average rates, we
believe that there are many smaller companies with higher earnings growth. Over
the next three to five years, we expect the Core Growth Portfolio companies to
grow earnings at 38% versus 14% for the Russell 3000 Growth Index companies.

 The NMSGI Index, consisting of the 500 fastest growing small stocks, aims to
eliminate the large cap bias of the NASDAQ in which Intel and Microsoft account
for 20% of the market. The index advanced just 7.3% for 1997 despite the fact
that 75% of its companies met or beat estimates. Additionally, earnings growth
in the index registered a 58% gain for the year versus a 10% gain for the S&P
500, illustrating the point that small companies grow faster than large ones.

Except for a few months in mid-1997, investors were unwilling to pay for
high-quality, high-earnings growth companies. Currently, uncertainty centered on
Asia has kept investors at bay. We believe that steadfast investors in this
style will be rewarded. In virtually all past periods, remaining invested in
this style has proven to be beneficial when the style returns to favor.

vary. All returns reflect reinvested dividends. The portfolio's holdings may
differ significantly from the securities in the index. The index is unmanaged

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 were pleased with the Growth & Income Portfolio's performance in 1997.
Despite a terrible November, our overweighting in the oil service sector helped
our performance dramatically. We ended the year with approximately 13% of our
assets in oil service. Despite the large gains we've seen over the last two
years, we do not think the cycle is over. The cable television sector is another
of our favorites and accounted for a large portion of our summer gains. At year
end we continued to maintain a significant weighting in the group.

In our opinion, small and mid-cap stocks remain undervalued relative to the
overall market. We still believe that many small-cap stocks offer higher
earnings growth potential in 1998 with less foreign exposure than most large-cap
multinationals. The biggest economic news of 1997 was the turmoil in Asia. The
big question for 1998 is what it will mean for the US economy. In all likelihood
it may mean a flood of imports to the US by spring, a reduction in GDP growth
and pressure on corporate earnings. Pricing power has not been good in general
and should become more negative for companies exposed to Asian competition.

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.

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

OBJECTIVE
- ---------

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

PERFORMANCE AS OF DECEMBER 31, 1997
- -----------------------------------

AVERAGE ANNUAL TOTAL RETURN:
Since inception (1/3/97)                  31.75%

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
- --------

The S&P 500 Index Portfolio began on January 3, 1997 with a few simple, but
critical goals: hold down expenses to enhance returns; invest new cash quickly;
and match the S&P 500 Index returns. Outperforming the actual index is a
difficult goal because funds incur operating expenses that an index does not.

Using regression analysis, industry weightings, market capital weightings, and
individual stock analysis, the portfolio was managed with only about 40 stock
holdings, and with S&P 500 stock index futures contracts hedged by commercial
paper and/or treasuries. This strategy did allow the portfolio to hold down
expenses, quickly invest cash and match the S&P 500 Index with very little
variance.

From January 3, 1997 through year-end the S&P 500 Index, with dividends
reinvested, rose 31.85%. Your S&P 500 Index Portfolio rose 31.75%, nearly
matching the "dividends reinvested" Index return even after portfolio expenses.

Expectations for 1998 are high, with average corporate earnings expected to grow
about 8% or better. However, the ongoing impact of the Asian recession, which
has reduced earnings forecasts for many American companies, has dampened
expectations. We look for the stock market to be flat to 10% higher in 1998.

                                          ----           -----

S&P 500 Index                            10,000          13,338

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 DECEMBER 31, 1997
- -----------------------------------

AVERAGE ANNUAL TOTAL RETURN:

Since inception (1/3/97)                               25.63%

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
- --------

Financial markets displayed increasing volatility during 1997, as sentiment
shifted dramatically. The Social Awareness Portfolio outperformed the Russell
2000 Index and a peer group of funds using social criteria, aided by strong
performance in the second and third quarters of the year. The largest sector
contributions to performance came from the Consumer Cyclical, Capital Goods and
Financial Services sectors.

We expect volatility in the overall market to continue, driven by concerns over
economic turmoil and the outlook for corporate profits. Companies selected for
the Social Awareness Portfolio have strong fundamentals, pass social criteria
and sell at a discount to estimated growth rates. We will take a disciplined
approach, using heightened volatility to establish positions with favorable
risk-reward characteristics.

STRATEGIC INCOME PORTFOLIO
OHIO NATIONAL FUND, INC.

OBJECTIVE
- ---------

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

PERFORMANCE AS OF DECEMBER 31, 1997
- -----------------------------------

Average Annual Total Return:
Since inception (1/3/97)             8.74%

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 last half of 1997, investors were presented with strong returns and
numerous surprises across all domestic asset classes. Strong returns were
recorded in bonds, REITs and the stock market despite international turmoil.
Bonds in particular were the beneficiary of market uncertainty.

Looking ahead, we expect a slowing world economy and dampened inflation
expectations for 1998. Thus, the bond market should become the performance
leader in 1998 owing to diminished issuance and strong demand. Earnings problems
related to an economic slowdown are likely to keep equity returns sub-par. The
Strategic Income Portfolio is positioned to take advantage of this situation by
focusing on longer maturity bond investments, and corporate issuers that derive
their earnings from domestic activities, as well as utilizing risk-management
strategies to mitigate any downturn in the equity markets.

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, 1997
- -----------------------------------

Average Annual Total Return:

Since inception (1/3/97)                      9.70%

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 latter half of 1997 was an ideal environment for the Stellar Portfolio. The
stock market advance stalled in early August, giving way to the formation of a
trading range in the broad indices. The Stellar Portfolio's asset mix served to
insulate investors from much of the volatility which enveloped the market. This
is the type of market for which the portfolio was intended. The REIT, bond and
cash-equivalent segments of the portfolio generated positive returns for the
period which served to offset the weakness in the domestic and international
equity holdings. The portfolio's allocation to fixed-income instruments rose the
second half of the year at the expense of international securities and cash
equivalents.

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.

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, 1997
- -----------------------------------

Average Annual Total Return:
Since inception (1/3/97)              28.28%

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 Relative Value Portfolio posted performance in line with the S&P 500 Index
during the latter half of 1997. This was achieved despite the stock market
turmoil caused by economic events in Asia. The most notable effect on the
portfolio's holdings were sharp price declines in technology and energy related
issues.

The portfolio is well positioned for the market conditions prevailing at the
start of 1998 as investors are displaying a distinct preference for large,
stable companies with visible earnings potential for the current year. The
portfolio continues to focus on the successful themes of the last two years,
consolidation trends in financial services and the impact of an aging population
on health care and services spending.

    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 sixteen 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.
    GLOBAL CONTRARIAN PORTFOLIO - long-term growth of capital by investing in
    foreign and domestic securities believed to be undervalued or presently out
    of favor.
    AGGRESSIVE GROWTH PORTFOLIO - capital growth.

    The following portfolios commenced operations on January 3, 1997:

    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.
    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.
    RELATIVE VALUE PORTFOLIO - maximum total return consistent with reasonable
    risk by investing primarily in equity securities.

    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 other portfolios, 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

                                       97

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, and Stellar 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 futures contracts in the S&P 500
Index Portfolio at December 31, 1997 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, and Stellar
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.

OHIO NATIONAL FUND, INC.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
December 31,1997

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 and Stellar 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, Aggressive Growth, and Core Growth
Portfolios: accumulated net investment loss has been decreased by $47,515,
$61,720, and $11,892, respectively, resulting in a reclassification adjustment
to decrease Paid-in capital in excess of par value by $47,515, $61,720, $11,892
respectively. This reclassification has no effect on net assets or net asset
value per share.

For Federal income tax purposes, the Bond, Core Growth, Stellar, and Relative
Value Portfolios had capital loss carryovers of $44,128, $447,567, $11,917, and
$2,446 respectively, at December 31, 1997. If not offset by capital gains,
$44,128 will expire in 2003 in the Bond Portfolio and $447,567, $11,917 and
$2,446 will expire in 2005 in the Core Growth , Stellar, and Relative Value
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.

Most expenses of the Fund can be directly attributed to a portfolio. Expenses
which cannot be directly attributed are allocated among the portfolios in the
Fund based on average 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.

INDEPENDENT AUDITORS' REPORT

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

We have audited the accompanying statements of assets and liabilities and the
schedules of investments of Ohio National Fund, Inc. (comprising, respectively,
the Equity, Money Market, Bond, Omni, International, Capital Appreciation, Small
Cap, Global Contrarian, Aggressive Growth, Core Growth, Growth & Income, S&P 500
Index, Social Awareness, Stategic Income, Stellar and Relative Value Portfolios)
as of December 31, 1997, and the related statements of operations, statements of
changes in net assets and the financial highlights for each of the periods
indicated herein. These financial statements and financial highlights are the
responsibility of the funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of December 31, 1997, by correspondence with
the custodian and brokers, and where replies are not received, we carried out
other appropriate auditing procedures. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the portfolios comprising Ohio National Fund, Inc. as of December 31, 1997,
and the results of their operations, the changes in their net assets and their
financial highlights for each of the periods indicated herein, in conformity
with generally accepted accounting principles.

OHIO NATIONAL VARIABLE ACCOUNT B
Notes to Financial Statements


(1)  BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Ohio National Variable Account B (the Account) is a separate account of The
     Ohio National Life Insurance Company (ONLIC) and all obligations arising
     under variable annuity contracts are general corporate obligations of
     ONLIC. The account has been registered as a unit investment trust under the
     Investment Company Act of 1940.

     Assets of the Account are invested in shares of Ohio National,  Fund,  Inc.
     (The Fund), a diversified open-end management investment company. The
     Fund's  investments are subject to varying degrees of market,  interest and
     financial risks; the issuers' abilities to meet certain  obligations may be
     affected by economic developments in their respective industries.

     Annuity reserves are computed for currently payable contracts according to
     the Progressive Annuity Mortality Table. The assumed interest rate is 3.5
     or 4.0 percent depending on the contract selected by the annuitant. Charges
     to annuity reserves for adverse mortality and express risk experience are
     reimbursed to the Account by ONLIC. Such amounts are included in risk and
     administrative expenses.

     Investments are valued at the net asset value of fund shares held at
     December 31, 1997. Share transactions are recorded on the trade date.
     Income and capital gain distributions are recorded on the ex-dividend date.
     Net realized capital gains of loss is determined on the basis of average
     cost.

     ONLIC performs investment advisory services on behalf of the Ohio National
     Fund, Inc. in which the Account invests. For these services, the Company
     receives fees from the mutual funds. These fees are paid to an affiliate of
     the Company.

     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 revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

OHIO NATIONAL VARIABLE ACCOUNT B
NOTES TO FINANCIAL STATEMENTS (CONTINUED)


(4)  RISK AND ADMINISTRATIVE EXPENSE

     ONLIC charges the Account's assets at the end of each day, equal to 0.25%
     on an annual basis, of the contract value for administrative expenses,
     based on premiums established at the time the contracts are issued.

     Although variable annuity payments differ according to the investment
     performance of the Accounts, they are not affected by mortality or expense
     experience because ONLIC assumes the expense risk and the mortality risk
     under the contracts. ONLIC charges the Accounts' assets for assuming those
     risks, based on the contract value at a rate presently ranging from 0.65%
     to 1.05% for mortality and expense risk on an annual basis.

     The expense risk assumed by ONLIC is the risk that the deductions for sales
     and administrative expenses provided for in the variable annuity contracts
     may prove insufficient to cover the cost of those terms.

     The mortality risk results from a provision in the contract in which ONLIC
     agrees to make annuity payments regardless of how long a particular
     annuitant or other payee lives and how long all annuitants or other payees
     as a class live if payment options involving life contingencies are chosen.
     Those annuity payments are determined in accordance with annuity purchase
     rate provisions established at the time the contracts are issued.

(5)  CONTRACT CHARGES

     No deduction for a sales charge is made from purchase payments. A
     contingent deferred sales charge ranging from 0% to 6% may be assessed by
     ONLIC when a contract is surrendered or a partial withdrawal of
     accumulation value is made before the annuity payout date.

     A transfer fee is charged for each transfer from one subaccount to another.
     The fee is charged against the contract owner's equity in the subaccount
     from which the transfer is effected.

     State premium taxes presently range from 0% to 2 1/2% for these contracts.
     In those jurisdictions permitting, such taxes will be deducted when annuity
     payments begin. Elsewhere, they will be deducted from purchase payments.

     Each year on the contract anniversary (or at the time of surrender of the
     contract), ONLIC will deduct a contract administration charge of $35 from
     the accumulation value to reimburse it for the expenses relating to the
     maintenance of the contract. Total contract charges for the Account
     amounted to approximately $80,000 during 1997.

(6)  FEDERAL INCOME TAXES

     Operations of the Account form a part of, and are taxed with, operations of
     ONLIC which is taxed as a life insurance company under the Internal Revenue
     Code. Taxes are the responsibility of the contract owner upon termination
     or withdrawal. No Federal income taxes are payable under the present law on
     dividend income or capital gains distribution from the Fund shares held in
     the Account or on capital gains realized by the Account on redemption of
     the Fund shares.

(7)  NOTE TO SCHEDULE 1

     Schedule 1 presents the components of the change in the unit values, which
     are based on average unit values and are the basis for determining contract
     owners' equity. This schedule is presented for each series, as applicable,
     in the following format:
     -  Beginning unit value
     -  Reinvested capital gains and dividends
        (This amount reflects the increase in the unit value due to capital gain
        and dividend distributions from the underlying mutual fund.)
     -  Unrealized gain (loss) 
        This amount reflects the increase (decrease) in the unit value resulting
        from the market appreciation (depreciation) of the fund.)
     -  Expenses
        (This amount reflects the decrease in the unit value due to Risk and
        Administrative Expenses discussed in note 4 to the financial
        statements.)
     -  Ending unit value
     -  Percentage increase (decrease) in unit value
