         FUND SUMMARIES

This prospectus provides information about ten funds offered by Nationwide
Separate Account Trust (together, the Funds).

Strong NSAT Mid Cap Growth Fund
(formerly Nationwide Strategic Growth Fund)

OBJECTIVE

The Fund seeks capital growth. The Fund's investment objective can be changed by
the Fund's Trustees without shareholder approval.

PRINCIPAL STRATEGIES

Villanova Mutual Fund Capital Trust (VMF) has selected Strong Capital
Management, Inc. as a subadviser to manage the Fund's portfolio on a day-to-day
basis. The Fund focuses on common stocks of U.S. and foreign companies that the
subadviser believes are reasonably priced and have above-average growth
potential. The Fund invests in stocks of small and medium size companies but its
portfolio can include stocks of companies of any size. The subadviser may decide
to sell a stock when the company's growth prospects become less attractive. The
subadviser's buy/sell strategy is not limited by the turnover rate of the Fund's
portfolio. The subadviser may participate in frequent portfolio transactions,
which will lead to higher transaction costs.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the subadviser's ability to assess economic conditions and
investment opportunities.

Stock market risk. Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. The stock market is affected
by numerous factors, including interest rates, the outlook for corporate
profits, the health of the national and world economies, national and world
social and political events, and the fluctuations of other stock markets around
the world.

Portfolio turnover risk. The Fund will attempt to buy securities with the intent
of holding them for investment, but the subadviser may engage in active and
frequent trading of securities if doing so is in the best interest of the Fund.
A higher portfolio turnover rate may result in higher transaction costs for the
Fund and increase the volatility of the Fund.

Foreign risk. Investments in foreign securities involve risks in addition to
those of U.S. investments. These risks include political and economic risks,
currency fluctuations, higher transaction costs, and delayed settlement.

Risks related to investing for growth. Different types of stocks tend to shift
into and out of favor with stock market investors depending on market and
economic conditions. Because the Fund focuses on growth-style stocks, the Fund's
performance may at times be better or worse than the performance of stock funds
that focus on other types of stocks, or that have a broader investment style.

Mid/small cap risk. The Fund's investments in smaller, newer companies may be
riskier than investments in larger, more established companies. The stocks of
medium-size and small companies are usually less stable in price and less liquid
than the stocks of larger companies.

For more detailed information about the Fund's investments and risks, see "More
About the Funds."

PERFORMANCE

The following bar chart and table show two aspects of the Fund: volatility and
performance. The bar chart shows the volatility -- or variability -- of the
Fund's annual total returns over time and shows that fund performance can change
from year to year. The annual returns shown in the bar chart do not include
charges that may be imposed by variable annuity contracts or variable life
insurance polices. The table shows the Fund's average annual total returns for
certain time periods compared to the returns of a broad-based securities index.
The bar chart and table provide some indication of the risks of investing in the
Fund. Remember, however, that past performance does not guarantee similar
results in the future.

    the S&P 400 Mid Cap Index whose stocks have higher price-to-book
    ratios -- gives a broad look at how the prices of growth style stocks of
    medium-size U.S. companies have performed. Unlike mutual funds, the
    S&P/Barra Mid Cap 400 Growth Index does not incur expenses. If expenses were
    deducted, the actual returns of this Index would be lower.

(2) VMF has agreed to waive management fees and, if necessary, to reimburse
    "Other Expenses" so that Total Annual Fund Operating Expenses will not
    exceed 1.00%. These waivers and reimbursements are voluntary and can be
    discontinued after prior notice to shareholders.

EXAMPLE

This example shows what a shareholder could pay in expenses over time. A
shareholder can also use this example to compare the cost of this Fund with
other mutual funds.

The example assumes that a shareholder invests $10,000 in the Fund for the time
periods indicated and sells all shares at the end of those time periods. It also
assumes a 5% return each year, the Fund's operating expenses will not change,
and there are no fee waivers or expense reimbursements in effect. Although a
shareholder's actual costs may be higher or lower, based on these assumptions
the cost would be:

         Fund Summaries

Nationwide Strategic Value Fund

OBJECTIVE

The Fund's primary investment objective is long-term capital appreciation, and
portfolio securities are selected primarily with a view to achievement of this
objective. The Fund's investment objective can be changed by the Fund's Trustees
without shareholder approval.

PRINCIPAL STRATEGIES

VMF has selected Schafer Capital Management, Inc. as a subadviser to manage the
Fund's portfolio on a day-to-day basis through a subcontract with Strong Capital
Management, Inc. The Fund invests primarily in common stocks of medium and
large-size companies. The subadviser selects stocks of companies that have
above-average growth potential, but also are inexpensive relative to market
averages. The Fund invests approximately equal amounts of its assets in the
stocks of the portfolio at the time of purchase, and generally invests all of
its assets in U.S. and foreign common stock and convertible securities. The
subadviser sells holdings when they are no longer attractive based on their
growth potential or price.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the subadviser's ability to assess economic conditions and
investment opportunities.

Stock market risk. Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. The stock market is affected
by numerous factors, including interest rates, the outlook for corporate
profits, the health of the national and world economies, national and world
social and political events, and the fluctuations of other stock markets around
the world.

Risks related to investing for value. Different types of stocks tend to shift
into and out of favor with stock market investors depending on market and
economic conditions. Because the Fund generally focuses on value-style stocks,
the Fund's performance may at times be better or worse than the performance of
stock funds that focus on other types of stocks, or that have a broader
investment style.

Mid cap risk. The Fund's investments in smaller, newer companies may be riskier
than investments in larger, more established companies. The stocks of
medium-size companies are usually less stable in price and less liquid than the
stocks of larger companies.

Foreign risk. Investments in foreign securities involve risks in addition to
those of U.S. investments. These risks include political and economic risks,
currency fluctuations, higher transaction costs, and delayed settlement.

About the Funds."

         Fund Summaries

Dreyfus NSAT Mid Cap Index Fund
(formerly Nationwide Mid Cap Index Fund)

OBJECTIVE

The Fund's investment objective is capital appreciation. The Fund's investment
objective can be changed by the Fund's Trustees without shareholder approval.

PRINCIPAL STRATEGIES

VMF has selected The Dreyfus Corporation as a subadviser to manage the Fund's
portfolio on a day-to-day basis. The Fund seeks to match the performance of the
Standard & Poor's MidCap 400 Index(1). To pursue this goal, the Fund generally
is fully invested in stocks included in this index, and in futures whose
performance is tied to the index.

The Fund attempts to have a correlation between its performance and that of the
index of at least 0.95, before expenses. A correlation of 1.00 would mean that
the Fund and the index were perfectly correlated.

The Fund generally invests in all 400 stocks in the S&P MidCap 400 in proportion
to their weighting in the index. The S&P MidCap 400 is composed of 400 stocks of
medium-size domestic and some Canadian companies with market capitalizations
ranging primarily between $100 million and $10 billion. Each stock is weighted
by its market capitalization, which means larger companies have greater
representation in the index than smaller ones. The Fund may also use stock index
futures as a substitute for the sale or purchase of securities.

Market capitalization is a common way to measure the size of a company based on
the price of its common stock; it's simply the number of outstanding shares of
the company multiplied by the current share price.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases.

Stock market risk. Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. The stock market is affected
by numerous factors, including interest rates, the outlook for corporate
profits, the health of the national and world economies, national and world
social and political events, and the fluctuations of other stock markets around
the world.

The Fund focuses on a more narrow portion of the overall stock market by
investing primarily in mid-cap companies. Therefore, the impact of these factors
on mid-cap companies may affect the Fund more than if the Fund were to invest
more broadly in the overall stock market.

Mid/small cap risk. The Fund's investments in smaller, newer companies may be
riskier than investments in larger, more established companies. The stocks of
medium-size and small companies are usually less stable in price and less liquid
than the stocks of larger companies.

Risks related to index funds. The Fund uses an indexing strategy. It does not
attempt to manage market volatility, use defensive strategies or reduce the
effects of any long-term periods of poor stock performance. The correlation
between Fund and index performance may be affected by the Fund's expenses,
changes in securities markets, changes in the composition of the index and the
timing of purchase and redemption of fund shares. In addition, an index fund has
operating and other expenses while an index does not. As a result, while the
Fund will attempt to track the S&P MidCap 400 as closely as possible, it will
tend to underperform the Index to some degree over time.

Risks related to stock index futures.  The Fund may invest in stock index
futures, which could carry additional risks such as losses due to unanticipated
market price movements and could also reduce the opportunity for gain.

About the Funds."

(2) VMF has agreed to waive management fees and, if necessary, to reimburse
    "Other Expenses" so that Total Annual Fund Operating Expenses will not
    exceed 0.65%. These waivers and reimbursements are voluntary and can be

EXAMPLE

This example shows what a shareholder could pay in expenses over time. A
shareholder can also use this example to compare the cost of this Fund with
other mutual funds.

The example assumes that a shareholder invests $10,000 in the Fund for the time
periods indicated and sells all shares at the end of those time periods. It also
assumes a 5% return each year, the Fund's operating expenses will not change,
and there are no fee waivers or expense reimbursements in effect. Although a
shareholder's actual costs may be higher or lower, based on these assumptions
the cost would be:

Nationwide Small Cap Value Fund

OBJECTIVE

The Fund's investment objective is capital appreciation through investment in a
diversified portfolio of equity securities of companies with a median market
capitalization of approximately $1 billion. The Fund's investment objective can
be changed by the Fund's Trustees without shareholder approval.

PRINCIPAL STRATEGIES

VMF has selected The Dreyfus Corporation as a subadviser to manage the Fund's
portfolio on a day-to-day basis. The Fund intends to pursue its investment
objective by investing, under normal market conditions, at least 75% of its
total assets in equity securities of companies whose equity market
capitalizations at the time of investment are similar to the market
capitalizations of companies in the Russell 2000(R) Index, known as small cap
companies. The Russell 2000, published by the Frank Russell Company, is an index
consisting of approximately 2000 companies with small market capitalizations
relative to the market capitalizations of other U.S. companies. As of December
31, 1999 the market capitalizations of companies in the Russell 2000 ranged from
approximately $100 million to $13 billion. The Fund may invest up to 20% of its
total assets in equity securities of foreign companies. The subadviser will sell
a stock if the subadviser no longer considers the company to be of value.

Market capitalization is a common way to measure the size of a company based on
the price of its common stock; it's simply the number of outstanding shares of
the company multiplied by the current share price.

The Fund will invest in stocks of U.S. and foreign companies which the
subadviser considers to be "value" companies. The subadviser generally believes
that such companies have relatively low price to book ratios, low price to
earnings ratios or higher than average dividend payments in relation to price.

Smaller capitalization companies are often undervalued for one of the following
reasons: (1) institutional investors, which currently represent a majority of
the trading volume in the shares of publicly traded companies, are often less
interested in smaller capitalization companies because of the difficulty of
acquiring a meaningful position without purchasing a large percentage of the
company's outstanding equity securities; and (2) such companies may not be
regularly researched by securities analysts, which could result in greater
discrepancies in valuation.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the subadviser's ability to assess economic conditions and
investment opportunities.

Stock market risk. Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. The stock market is affected
by numerous factors, including interest rates, the outlook for corporate
profits, the health of the national and world economies, national and world
social and political events, and the fluctuations of other stock markets around
the world.

The Fund focuses on a more narrow portion of the overall stock market by
investing primarily in companies with smaller market capitalizations. Therefore,
the impact of these factors on small companies may affect the Fund more than if
the Fund were to invest more broadly in the overall stock market.

Mid/small cap risk. The Fund's investments in smaller, newer companies may be
riskier than investments in larger, more established companies. The stocks of
medium-size and small companies are usually less stable in price and less liquid
than the stocks of larger companies.

Foreign risk. Investments in foreign securities involve risks in addition to
those of U.S. investments. These risks include political and economic risks,
currency fluctuations, higher transaction costs, and delayed settlement.

Risks related to investing for value. Different types of stocks tend to shift
into and out of favor with stock market investors depending on market and
economic conditions. Because the Fund generally focuses on value-style stocks,
the Fund's performance at times may be better or worse than the performance of
stock funds that focus on other types of stocks, or that have a broader
investment style.

About the Funds."

PERFORMANCE

The following bar chart and table show two aspects of the Fund: volatility and
performance. The bar chart shows the volatility -- or variability -- of the
Fund's annual total returns over time and shows that fund performance can change
from year to year. The annual returns shown in the bar chart do not include
charges that may be imposed by variable annuity contracts or variable life
insurance polices. The table shows the Fund's average annual total returns for
certain time periods compared to the returns of a broad-based securities index.
The bar chart and table provide some indication of the risks of investing in the
Fund. Remember, however, that past performance does not guarantee similar

Nationwide Small Cap Growth Fund
(formerly Nationwide Select Advisers Small Cap Growth Fund)

OBJECTIVE

The Fund seeks capital growth. The Fund's investment objective can be changed by
the Fund's Trustees without shareholder approval.

PRINCIPAL STRATEGIES

The Fund seeks to achieve its investment objective from a broadly diversified
portfolio of equity securities issued by U.S. and foreign companies with market
capitalizations in the range of companies represented by the Russell 2000, known
as small cap companies. Under normal market conditions, the Fund will invest at
least 65% of its total assets in the equity securities of small cap companies.
The Russell 2000, published by The Frank Russell Company, is an index consisting
of approximately 2000 companies with small market capitalizations relative to
the market capitalizations of other U.S. companies. As of December 31, 1999, the
market capitalizations for companies in the Russell 2000 range from
approximately $100 million to $13 billion. The balance of the Fund's assets may
be invested in equity securities of larger cap companies. Equity securities
include preferred stocks, securities convertible into common stock and warrants
for the purchase of common stock. The Fund may also invest in foreign
securities.

Market capitalization is a common way to measure the size of a company based on
the price of its common stock; it's simply the number of outstanding shares of
the company multiplied by the current share price.

As part of its responsibilities to the Fund, VMF initially selects the Fund's
subadvisers and monitors their performance on an ongoing basis. VMF has chosen
Miller Anderson & Sherrerd, LLP, Neuberger Berman, LLC and Waddell & Reed
Investment Management Company each to manage a portion of the Fund. The
subadvisers have been chosen because they approach investing in small cap
companies different ways. VMF believes that diversification among securities and
styles will increase the potential for investment return and reduce risk and
volatility. For a description of the investment strategies used by each
subadviser, see "Investment Strategies of the Multiple Subadvisers."

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by each subadviser's ability to assess economic conditions and
investment opportunities.

Stock market risk. Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. The stock market is affected
by numerous factors, including interest rates, the outlook for corporate
profits, the health of the national and world economies, national and world
social and political events, and the fluctuations of other stock markets around
the world.

The Fund focuses on a more narrow portion of the overall stock market by
investing primarily in companies with smaller market capitalizations. Therefore,
the impact of these factors on small companies may affect the Fund more than if
the Fund were to invest more broadly in the overall stock market.

Mid/small cap risk. The Fund's investments in smaller, newer companies may be
riskier than investments in larger, more established companies. The stocks of
medium-size and small companies are usually less stable in price and less liquid
than the stocks of larger companies.

Risks related to investing for growth. Different types of stocks tend to shift
into and out of favor with stock market investors depending on market and
economic conditions. Because the Fund focuses on growth-style stocks, the Fund's
performance may at times be better or worse than the performance of stock funds
that focus on other types of stocks, or that have a broader investment style.

Foreign risk. Investments in foreign securities involve risks in addition to
those of investments in U.S. companies. These risks include political and
economic risks, currency fluctuations, higher transaction costs, and delayed
settlement.

INVESTMENT STRATEGIES OF THE MULTIPLE SUBADVISERS

The following is a description of the investment strategies used by each
subadviser of this multi-managed fund. Each subadviser manages a portion of the
Fund's assets in accordance with the investment objective and principal
strategies as described previously.

Miller Anderson & Sherrerd, LLP focuses on companies that demonstrate high
earnings growth rates, growth stability, and rising profitability. In
particular, the subadviser invests in companies that appear to be capable of
producing earnings that consistently beat market expectations. The subadviser
uses computer analysis to identify stocks based on earnings' predictions and
then conducts extensive fundamental research, examining financial records and
identifying those companies with the most attractive earnings revisions.
Finally, the subadviser reviews the valuation of these stocks to eliminate the
most overvalued stocks from consideration. The subadviser also follows a strict
sell discipline and will sell stocks when their earnings revision scores fall to
unacceptable levels, fundamental research uncovers unfavorable trends, or
valuations are excessive relative to the stocks' growth prospects.

Neuberger Berman, LLC's growth equity group takes a growth approach to selecting
stocks, looking for new companies that are in the developmental stage as well as
older companies that appear poised to grow because of new products, markets or
management. Factors in identifying these firms may include financial strength, a
strong position relative to competitors and a stock price that is reasonable in
light of its growth rate.

Neuberger Berman follows a disciplined selling strategy, and may sell a stock
when it reaches a target price, fails to perform as expected, or appears
substantially less desirable than another stock.

Waddell & Reed Investment Management Company (WRIMCO) seeks companies whose
earnings it believes are likely to grow faster than the economy. WRIMCO
emphasizes relatively new or unseasoned companies in their early stages of
development or smaller companies positioned in new or emerging industries where
there is opportunity for rapid growth. WRIMCO may look at a number of factors
relating to a company, such as:

- aggressive or creative management

- technological or specialized expertise

- new or unique products or services

- entry into new or emerging industries

In general, WRIMCO may sell a security if it determines that the stock no longer
offers significant growth potential, which may be due to a change in the
business or management of the company or a change in the industry of the
company. WRIMCO may also sell a security to take advantage of more attractive
investment opportunities or to raise cash.

         Fund Summaries

Nationwide Global 50 Fund
(formerly Nationwide Global Equity Fund)

OBJECTIVE

The Fund seeks to provide a high total return from a concentrated portfolio of
global equity securities. The Fund's investment objective can be changed by the
Fund's Trustees without shareholder approval.

PRINCIPAL STRATEGIES

VMF has selected J.P. Morgan Investment Management Inc. as a subadviser to
manage the Fund's portfolio on a day-to-day basis. The Fund invests in
approximately fifty stocks of primarily large and mid cap companies located
throughout the world. Using its global perspective, the subadviser uses its
investment process to identify those stocks which in its view have an
exceptional return potential. Under normal conditions, the Fund invests in
stocks of at least three countries, including the United States, and in a
variety of industries; the Fund is not constrained by geographic limits and will
not concentrate in any one industry. The Fund may invest in both developed and
emerging markets. The Fund may invest substantially in securities denominated in
foreign currencies and actively seeks to enhance returns through managing
currency exposure. To the extent that the Fund hedges its currency exposure to
the U.S. dollar, it may reduce the effects of currency fluctuations. The Fund
may also hedge from one foreign currency to another, although emerging markets
investments are typically unhedged.

   The subadviser follows a Global Equity Investment Process.

   Research and valuation. Research findings allow the subadviser to rank
   companies according to their relative value: combined with the
   subadviser's qualitative view, the most attractive investment
   opportunities in a universe of 2,500 stocks are identified.

   The subadviser takes an in-depth look at company prospects over a
   relatively long period -- often as much as five years -- rather than
   focusing on near-term expectations. This approach is designed to provide
   insight into a company's growth potential. The subadviser's in-house
   research is compiled by an extensive worldwide network of over 120 career
   analysts following 2,500 stocks in 22 countries. The subadviser produces
   valuation rankings of issuers with a market capitalization generally
   greater than $1.5 billion with the help of a variety of models that
   quantify its research team's findings.

   Stock Selection. Using research as the basis for investment decisions, the
   Fund's portfolio managers construct a concentrated stock portfolio
   representing companies which in their view have an exceptional return
   potential relative to other companies. The subadviser's stock selection
   focuses on highly rated undervalued companies which also meet certain
   other criteria, such as responsiveness to industry themes (e.g.
   consolidation/restructuring), conviction in management, the company's
   product positioning, and catalysts that may positively affect a stock's
   performance over the next twelve months.

   Currency Management. The subadviser actively manages currency exposure to
   manage risk and possibly enhance the Fund's returns. The Fund has access
   to the subadviser's currency specialists to determine the extent and
   nature of its exposure to various foreign currencies.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the subadviser's ability to assess economic conditions and
investment opportunities.

Concentration risk. The Fund may invest in fewer stocks than other global equity
funds. This concentration increases the risk and potential of the Fund. With a
concentrated portfolio of securities, it is possible that the Fund could have
returns that are significantly more volatile than relevant market indices and
other, more diversified mutual funds. Because the Fund holds a relatively small
number of securities, a large movement in the price of a stock in the portfolio
could have a larger impact on the Fund's share price than would occur if the
Fund held more securities.

Stock market risk. Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. The stock market is affected
by numerous factors, including interest rates, the outlook for corporate
profits, the health of the national and world economies, national and world
social

                                       12
<PAGE>   14

and political events, and the fluctuations of other stock markets around the
world.

Mid/small cap risk. The Fund's investments in smaller, newer companies may be
riskier than investments in larger, more established companies. The stocks of
medium-size and small companies are usually less stable in price and less liquid
than the stocks of larger companies.

Foreign risk. Investments in foreign securities involve risks in addition to
those of U.S. investments. These risks include political and economic risks,
currency fluctuations, higher transaction costs, and delayed settlement.
Emerging market countries are generally considered to be less economically
mature than developed nations. Emerging market countries may be more likely to
experience political turmoil or rapid changes in economic conditions, and
issuers in those countries may be in more precarious financial condition. These
characteristics can cause securities in emerging market countries to experience
significant price volatility and bear a greater risk of loss of value.

Derivative risk. The Fund invests in securities that are considered to be
derivatives. The value of derivatives (like futures and options) is dependent
upon the performance of underlying assets, securities or indices. If the
underlying assets, securities or indices do not preform as expected, the value
of the derivative will decrease. Derivatives are more volatile and riskier than
traditional investments. To the extent the Fund enters into these transactions,
their success will depend upon the subadviser's ability to predict pertinent
market movement.

About the Funds."

This example shows what a shareholder could pay in expenses over time. A
shareholder can also use this example to compare the cost of this Fund with
other mutual funds.

The example assumes that a shareholder invests $10,000 in the Fund for the time
periods indicated and sells all shares at the end of those time periods. It also
assumes a 5% return each year, the Fund's operating expenses will not change,
and there are no fee waivers or expense reimbursements in effect. Although a
shareholder's actual costs may be higher or lower, based on these assumptions
the cost would be:

Federated NSAT Equity Income Fund
(formerly Nationwide Equity Income Fund)

OBJECTIVE

The Fund's investment objective is above average income and capital
appreciation. The Fund's investment objective can be changed by the Fund's
Trustees without shareholder approval.

PRINCIPAL STRATEGIES

VMF has selected Federated Investment Counseling as a subadviser to manage the
Fund's portfolio on a day-to-day basis. The Fund pursues its investment
objective by investing primarily in income producing U.S. and foreign equity
securities and securities that are convertible into common stock.

The subadviser ordinarily uses the "blend" style of investing, selecting
securities that may have a comparatively low volatility in share price relative
to the overall equity market and that may provide relatively high dividend
income, as well as securities that may offer superior growth prospects. When the
subadviser uses a "value" style of investing, the price of the securities held
by the Fund may not, under certain market conditions, increase as rapidly as
stocks selected primarily for their growth attributes.

To determine the timing of purchases of portfolio securities, the subadviser
compares the current stock price of an issuer with the subadviser's judgment as
to that stock's current and expected value based on projected future earnings.
The subadviser sells a portfolio security if it determines that the issuer's
prospects have deteriorated, or if it finds an attractive security which the
subadviser deems has superior risk and return characteristics to a security held
by the Fund.

Companies that are generally in the same industry may be grouped together in
broad categories called sectors. The subadviser diversifies the Fund's
investments, limiting the Fund's risk exposure with respect to individual
securities and industry sectors. In attempting to remain relatively sector-
neutral, and in order to manage sector risk, the subadviser attempts to limit
the Fund's exposure to each industry sector in the S&P 500 Index, as a general
matter, to not less than 80% nor more than 120% of the S&P 500 Index's
allocation to that sector. The S&P 500 Index, published by Standard & Poor's
Corporation, is an index consisting of approximately 500 widely-held stocks of
large U.S. companies.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the subadviser's ability to assess economic conditions and
investment opportunities.

Stock market risk. Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. The stock market is affected
by numerous factors, including interest rates, the outlook for corporate
profits, the health of the national and world economies, national and world
social and political events, and the fluctuations of other stock markets around
the world.

Sector risk. Companies that are generally in the same industry may be grouped
together in broad categories called sectors. Sector risk is the risk that a
certain sector of the economy (e.g., the health care or entertainment industry)
may perform differently than other sectors or the market as a whole. As the
subadviser allocates more of the Fund's portfolio holdings to a particular
sector, the Fund's performance will be more susceptible to any economic,
business or other developments which generally affect that sector.

Investment style risk. Securities with different characteristics tend to shift
in and out of favor depending upon market and economic conditions as well as
investor sentiment. A fund may outperform other funds that employ a different
style. The Fund may employ a combination of styles that impact its risk
characteristics, such as growth and value investing. Growth stocks may be more
volatile than other stocks because they are more sensitive to investor
perceptions of the issuing company's growth of earnings potential. Growth
oriented funds will typically underperform when value investing is in favor.
Value stocks are those which are out of favor or undervalued in comparison to
their peers due to adverse business developments or other factors. Value
oriented funds will typically underperform when growth investing is in favor.

About the Funds."

PERFORMANCE

The following bar chart and table show two aspects of the Fund: volatility and
performance. The bar chart shows the volatility -- or variability -- of the
Fund's annual total returns over time and shows that fund performance can change
from year to year. The annual returns shown in the bar chart do not include
charges that may be imposed by variable annuity contracts or variable life
insurance polices. The table shows the Fund's average annual total returns for
certain time periods compared to the returns of a broad-based securities index.
The bar chart and table provide some indication of the risks of investing in the

J.P. Morgan NSAT Balanced Fund
(formerly Nationwide Balanced Fund)

OBJECTIVE

The Fund seeks a high total return from a diversified portfolio of equity and
fixed income securities. The Fund's investment objective can be changed by the
Fund's Trustees without shareholder approval.

PRINCIPAL STRATEGIES

VMF has selected J.P. Morgan Investment Management Inc. as a subadviser to
manage the Fund's portfolio on a day-to-day basis.

To achieve its objective, the Fund, under normal circumstances, invests
approximately 60% of its assets in equity securities and 40% of its assets in
fixed income securities (including U.S. Government, corporate, mortgage-backed
and asset-backed securities). The equity securities held by the Fund generally
are common stocks of large and medium sized companies included in the Standard &
Poor's 500 Index.

The fixed income securities held by the Fund will generally be investment grade
securities, or unrated securities of comparable quality, although a portion of
the Fund's fixed income securities will be invested in securities rated below
investment grade (commonly known as junk bonds). All ratings are determined at
the time of investment. Any subsequent rating downgrade of a debt obligation
will be monitored by Fund management to consider what action, if any, the Fund
should take consistent with its investment objective. There is no requirement
that any such securities must be sold if downgraded.

   Investment grade securities are taxable debt securities, including
   corporate bonds and other debt instruments, that have been rated within
   the four highest rating categories by a nationally recognized rating
   agency, such as Standard & Poor's Rating Group or Moody's Investors
   Service, Inc. The rating agency evaluates a debt security, measures the
   issuer's financial condition and stability, and assigns a rating to the
   security. By measuring the issuer's ability to pay back the debt, ratings
   help investors evaluate the safety of their bond investments.

   Medium-grade securities are obligations rated in the fourth highest rating
   category by any rating agency. Medium-grade securities, although
   considered investment grade, have speculative characteristics and may be
   subject to greater fluctuations in value than higher-rated securities. In
   addition, the issuers of medium-grade securities may be more vulnerable to
   adverse economic conditions or changing circumstances than issuers of
   higher-rated securities.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the subadviser's ability to assess economic conditions and
investment opportunities.

Stock market risk. Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. The stock market is affected
by numerous factors, including interest rates, the outlook for corporate
profits, the health of the national and world economies, national and world
social and political events, and the fluctuations of other stock markets around
the world.

Interest rate risk. Interest rate risk is the risk that increases in market
interest rates may decrease the value of debt securities held by the Fund. In
general, the prices of debt securities fall when interest rates increase and
rise when interest rates decrease. Typically, the longer the maturity of a debt
security, the more sensitive it is to price shifts as a result of interest rate
changes.

Credit risk. Credit risk is the risk that the issuer of a debt security will be
unable to make the required payments of interest and/or repay the principal when
due. In addition, there is a risk that the rating of a debt security may be
lowered if an issuer's financial condition changes, which may lead to a greater
price fluctuation in the Fund. These risks are particularly strong for junk
bonds and other lower rated securities.

                                       17
<PAGE>   19

         Fund Summaries

Lower-rated securities risk. Investment in lower-rated or high yield securities
involves substantial risk of loss. These securities are considered speculative
with respect to the issuer's ability to pay interest and principal when due and
are susceptible to default or decline in market value due to adverse economic
and business developments. The market values of high yield securities tends to
be very volatile, and these securities are less liquid than investment grade
debt securities. For these reasons, an investment in the Fund is subject to the
following specific risks:

- increased price sensitivity to changing interest rates and to adverse economic
  and business developments

- greater risk of loss due to default or declining credit quality

- greater likelihood that adverse economic or company specific events will make
  the issuer unable to make interest and/or principal payments when due

- negative market sentiments toward high yield securities may depress their
  price and liquidity. If this occurs, it may become difficult to price or
  dispose of a particular security held by the Fund.

Prepayment and extension risk. The issuers of mortgage-backed and asset-backed
securities may be able to repay principal in advance, and are especially likely
to do so when interest rates fall. Changes in prepayment rates can make the
price and yield of mortgage- and asset-backed securities volatile. When
mortgage- and asset-backed securities are prepaid, the Fund may have to reinvest
the proceeds from the repayment at lower rates. In addition, rising interest
rates may cause prepayments to occur at slower than expected rates thereby
effectively lengthening the maturity of the security and making the security
more sensitive to interest rate changes. Extension risk is the risk that
anticipated payments on principal may not occur, typically because of a rise in
interest rates, and the expected maturity of the security will increase. During
periods of rapidly rising interest rates, the anticipated maturity of a security
may be extended past what the portfolio manager anticipated, affecting the
maturity and volatility of the Fund and may cause the security's market value to
decline.

Foreign risk. Investments in foreign securities involve risks in addition to
those of investments in U.S. companies. These risks include political and
economic risks, currency fluctuations, higher transaction costs, and delayed
settlement.

About the Funds."

         Fund Summaries

MAS NSAT Multi Sector Bond Fund
(formerly Nationwide Multi Sector Bond Fund)

OBJECTIVE

The primary objective of the Fund is to seek above average total return over a
market cycle of three to five years. The Fund's investment objective can be
changed by the Fund's Trustees without shareholder approval.

PRINCIPAL STRATEGIES

VMF has selected Miller Anderson & Sherrerd, LLP as a subadviser to manage the
Fund's portfolio on a day-to-day basis. The Fund invests in a diversified
portfolio of U.S. and foreign fixed income securities, including high yield
securities (commonly referred to as "junk bonds") and emerging markets
securities. The subadviser will use futures, swaps and other derivatives in
managing the Fund.

The subadviser determines the Fund's overall maturity and duration targets and
sector allocations. The portfolio managers then select particular securities for
the Fund in various sectors within those overall guidelines. The subadviser may
increase or decrease the Fund's exposure to interest rate changes based on its
outlook for the economy, interest rates and inflation. The Fund invests varying
amounts in U.S. and foreign securities (including emerging market securities),
and investment grade and high yield securities, based on the subadviser's
perception of their relative values.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the subadviser's ability to assess economic conditions and
investment opportunities.

Interest rate risk. Interest rate risk is the risk that increases in market
interest rates may decrease the value of debt securities held by the Fund. In
general, the prices of debt securities fall when interest rates increase and
rise when interest rates decrease. Typically, the longer the maturity of a debt
security, the more sensitive it is to price shifts as a result of interest rate
changes.

Credit risk. Credit risk is the risk that the issuer of a debt security will be
unable to make the required payments of interest and/or repay the principal when
due. In addition, there is a risk that the rating of a debt security may be
lowered if an issuer's financial condition changes, which may lead to a greater
price fluctuation in the Fund. These risks are particularly strong for lower
rated securities.

Prepayment and extension risk. The issuers of mortgage-backed and asset-backed
securities may be able to repay principal in advance, and are especially likely
to do so when interest rates fall. Changes in prepayment rates can make the
price and yield of mortgage- and asset-backed securities volatile. When
mortgage- and asset-backed securities are prepaid, the Fund may have to reinvest
the proceeds from the repayments at lower rates. In addition, rising interest
rates may cause prepayments to occur at slower than expected rates, thereby
effectively lengthening the maturity of the security and making the security
more sensitive to interest rate changes. Extension risk is the risk that
anticipated payments on principal may not occur, typically because of a rise in
interest rates, and the expected maturity of the security will increase. During
periods of rapidly rising interest rates, the anticipated maturity of a security
may be extended past what the portfolio manager anticipated, affecting the
maturity and volatility of the Fund and may cause the security's value to
decline.

Foreign risk. Investments in foreign securities involve risks in addition to
those of investments in U.S. companies. These risks include political and
economic risks, currency fluctuations, higher transaction costs, and delayed
settlement. Emerging market countries are generally considered to be less
economically mature than developed nations. Emerging market countries may be
more likely to experience political turmoil or rapid changes in economic
conditions, and issuers in those countries may be in more precarious financial
condition. These characteristics can cause securities in emerging market
countries to experience significant price volatility and bear a greater risk of
loss in value.

Derivative risk. The Fund invests in securities that are considered to be
derivatives. The value of derivatives (like futures and options) is dependent
upon the performance of underlying assets, securities or indicies. If the
underlying assets, securities or indicies do not perform as expected, the value
of the derivative will decrease. Derivatives are more volatile and riskier than
traditional investments. To the extent the Fund enters into these transactions,
their success will depend upon the subadviser's ability to predict pertinent
market movement.

Lower-rated securities risk. Investment in lower-rated or high yield securities
involves substantial risk of loss. These securities are considered speculative
with respect to the issuer's ability to pay interest and principal when due and
are susceptible to default or decline in market value due to adverse economic
and business developments. The market values of high yield securities tends to
be very volatile, and these securities are less liquid than investment grade
debt

                                       20
<PAGE>   22

securities. For these reasons, an investment in the Fund is subject to the
following specific risks:

- Increased price sensitivity to changing interest rates and to adverse economic
  and business developments

- Greater risk of loss due to default or declining credit quality

- Greater likelihood that adverse economic or company specific events will make

PERFORMANCE

The following bar chart and table show two aspects of the Fund: volatility and
performance. The bar chart shows the volatility -- or variability -- of the
Fund's annual total returns over time and shows that fund performance can change
from year to year. The annual returns shown in the bar chart do not include
charges that may be imposed by variable annuity contracts or variable life
insurance polices. The table shows the Fund's average annual total returns for
certain time periods compared to the returns of a broad-based securities index.
The bar chart and table provide some indication of the risks of investing in the
Fund. Remember, however, that past performance does not guarantee similar
results in the future.

assumes a 5% return each year, the Fund's operating expenses will not change,
and there are no fee waivers or expense reimbursements in effect. Although a
shareholder's actual costs may be higher or lower, based on these assumptions
the cost would be:

         Fund Summaries

Federated NSAT High Income Bond Fund
(formerly Nationwide High Income Bond Fund)

OBJECTIVE

The Fund seeks to provide high current income. The Fund's investment objective
can be changed without shareholder approval.

PRINCIPAL STRATEGIES

VMF has selected Federated Investment Counseling as a subadviser to manage the
Fund's portfolio on a day-to-day basis. The Fund provides exposure to the
high-yield, lower-rated corporate bond market. At least 65% of the Fund's total
assets are invested in corporate bonds that are rated BBB or lower by a rating
agency or that are unrated but of comparable quality. There is no minimum
acceptable rating for a security to be purchased or held in the Fund's
portfolio.

The subadviser actively manages the Fund's portfolio, seeking to realize the
potentially higher returns of high yield bonds by minimizing default risk and
other risks through security selection and diversification. Some of the fixed
income securities may be convertible into stock of the issuer or otherwise react
more closely to movements of the stock market rather than the bond market.

The methods by which the subadviser attempts to reduce the risks involved in
lower-rated securities include:

- Credit Research. The subadviser performs its own credit analysis in addition
  to using rating agencies and other sources, and may have discussions with the
  issuer's management or other investment analysts regarding issuers. The
  subadviser performs a credit-intensive, fundamental analysis of the financial
  records of an issuer which focuses on the financial condition of high yield
  issuers. In selecting a portfolio security, the subadviser also analyzes the
  issuer's business and product strength, competitive position and
  responsiveness to changing business and market conditions, management
  expertise, and financial condition and anticipated cash flow and earnings to
  assess whether the security's risk is commensurate with its potential return.
  In evaluating an issuer, the subadviser places special emphasis on the
  estimated current value of the issuer's assets rather than its historical
  cost.

- Diversification. The subadviser invests in securities of many different
  issuers, industries, and economic sectors to reduce portfolio risk.

- Economic Analysis. The subadviser analyzes current developments and trends in
  the economy and in the financial markets.

Sell decisions occur when the subadviser's fundamental outlook changes or when
its fundamental outlook differs from consensus as determined by over- (or
under-) valuation in the marketplace. In both cases, fundamental analysis drives
the sell process.

The fixed income securities that the Fund purchases include corporate debt
securities, zero coupon securities, convertible securities and preferred stocks.
The Fund may also invest in fixed income securities of issuers based outside the
U.S.; however, the securities of foreign issuers in which the Fund invests are
primarily traded in the U.S. and are denominated in U.S. dollars.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the subadviser's ability to assess economic conditions and
investment opportunities.

Interest rate risk. Interest rate risk is the risk that increases in market
interest rates may decrease the value of debt securities held by the Fund. In
general, the prices of debt securities fall when interest rates increase and
rise when interest rates decrease. Typically, the longer the maturity of a debt
security, the more sensitive it is to price shifts as a result of interest rate
changes.

Credit risk. Credit risk is the risk that the issuer of a debt security will be
unable to make the required payments of interest and/or repay the principal when
due. In addition, there is a risk that the rating of a debt security may be
lowered if an issuer's financial condition changes, which may lead to a greater
price fluctuation in the Fund. These risks are particularly strong for
lower-rated securities.

Lower-rated securities risk. Investment in lower-rated or high yield securities
involves substantial risk of loss. These securities are considered speculative
with respect to the issuer's ability to pay interest and principal when due and
are susceptible to default or decline in market value due to adverse economic
and business developments. The market values of high yield securities tends to
be very volatile, and these securities are less liquid than investment grade
debt securities. For these reasons an investment in the Fund is subject to the
following specific risks:

- Increased price sensitivity to changing interest rates and to adverse economic
  and business developments

- Greater risk of loss due to default or declining credit quality

                                       22
<PAGE>   24

- Greater likelihood that adverse economic or company specific events will make
  the issuer unable to make interest and/or principal payments when due

- Negative market sentiments toward high yield securities may depress their
  price and liquidity. If this occurs, it may become difficult to price or
  dispose of a particular security in the Fund.

Foreign risk. Investments in foreign securities involve risks in addition to
those of investments in U.S. companies. These risks include political and
economic risks, currency fluctuations, higher transaction costs, and delayed
settlement.

Call risk. Call risk is the possibility that an issuer may redeem a debt
security before maturity ("call"). An increase in the likelihood of a call may
reduce the security's price. If a debt security is called, the Fund may have to
reinvest the proceeds in other debt securities with lower interest rates, higher
credit risks, or other less favorable characteristics.

Liquidity risk. Liquidity risk is the risk that a security cannot be sold, or
cannot be sold quickly, at an acceptable price.

About the Funds."

         MORE ABOUT THE FUNDS

PRINCIPAL RISKS AND TECHNIQUES

The Funds may use the following principal investment techniques to increase
returns, protect assets or diversify investments. These techniques are subject
to certain risks. For additional information about the Funds' investment
strategies and techniques, see the Statement of Additional Information.

Principal Risks

SMALL CAP RISK. Historically, the securities of small cap companies have been
more volatile in price than larger company securities, especially over the short
term. Among the reasons for the greater price volatility are the less certain
growth prospects of small companies, the lower degree of liquidity in the
markets for such securities, the greater impact caused by changes in investor
perception of value, and the greater sensitivity of small cap companies to
changing economic conditions. In addition, small cap companies may:

- lack depth of management

- lack a proven track record

- be unable to generate funds necessary for growth or development

- be developing or marketing new products or services for which markets are not
  yet established and may never become established

- market products or services which may become quickly obsolete.

Small cap companies in the technology and biotechnology industries may be
subject to abrupt or erratic price movements. Therefore, while small cap
companies may offer greater opportunities for capital growth than larger, more
established companies, they also involve greater risks and should be considered
speculative.

FOREIGN RISK -- Foreign security investments involve special risks not present
in U.S. investments that can increase the risk that a Fund may lose money.

COUNTRY -- General securities market movements in any country in which a Fund
has investments are likely to affect the value of a Fund's securities that trade
in the country. These movements will affect a Fund's share price and a Fund's
performance. The political, economic and social structures of some countries in
which a Fund invests may be less stable and more volatile than those in the U.S.
The risks of investing in these countries include the possibility of the
imposition of exchange controls, currency devaluations, foreign ownership
limitations, expropriation, restrictions on removal of currency or other assets,
nationalization of assets, punitive taxes and certain custody and settlement
risks.

FOREIGN MARKETS -- A Fund is subject to the risk that because there are
generally fewer investors in foreign markets and a smaller number of securities
traded each day, it may make it difficult for a Fund to buy and sell certain
securities. In addition, prices of foreign securities may go up and down more
than prices of securities traded in the U.S. Also, brokerage commissions and
other costs of buying and selling securities often are higher in foreign
countries than they are in the United States. This reduces the amount the Fund
can earn on its investments.

GOVERNMENTAL SUPERVISION AND REGULATION/ACCOUNTING STANDARDS -- Foreign
companies are not subject to the same disclosure, accounting, auditing and
financial reporting standards and practices as U.S. companies. A Fund may have
greater difficulty voting proxies, exercising shareholder rights, pursuing legal
remedies and obtaining judgments with respect to foreign investments in foreign
courts than with respect to U.S. companies in U.S. courts. Many foreign
governments supervise and regulate stock exchanges, brokers and the sale of
securities less than the U.S. does. Other countries may not have laws to protect
investors the way that the U.S. securities laws do. Accounting standards in
other countries are not necessarily the same as in the U.S. If the accounting
standards in another country do not require as much detail as U.S. accounting
standards, it may be harder for a Fund's portfolio manager to completely and
accurately determine a company's financial condition.

CURRENCY -- Some of a Fund's investments may be denominated in foreign
currencies. Changes in foreign currency exchange rates will affect the value of
what a Fund owns and a Fund's share price. Generally, when the U.S. dollar rises
in value against a foreign currency, an investment in that country loses value
because that currency is worth fewer U.S. dollars. Devaluation of currency by a
country's government or banking authority also has a significant impact on the
value of any securities denominated in that currency. In addition, if the
currency in which a Fund receives dividends, interest or other payments declines
in value against the U.S. dollar before such income is distributed as dividends
to shareholders or converted to U.S. dollars, the Fund may have to sell
portfolio securities to obtain sufficient cash to pay such dividends out to its
shareholders.

EUROPEAN ECONOMIC AND MONETARY UNION (EMU) -- A number of European countries
have entered into EMU in an effort to reduce trade barriers between themselves
and eliminate fluctuations in their currencies. EMU has established a single
European currency (the euro), which was introduced in January 1, 1999 and is
expected to replace the existing national currencies of all initial EMU
participants by July 1,

                                       24
<PAGE>   26

2002. Certain securities (beginning with government and corporate bonds) were
redenominated in the euro. These securities trade and make dividend and other
payments only in euros. Like other investment companies and business
organizations, including the companies in which the Funds invest, the Funds
could be adversely affected:

- If the transition to euro, or EMU as a whole, does not proceed as planned.

- If a participating country withdraws from EMU.

- If the computing, accounting and trading systems used by a Fund's service
  providers, or by other entities with which the Fund or its service providers
  do business, are not capable of recognizing the euro as a distinct currency.

Principal Investment Techniques

GROWTH AND VALUE STOCKS. Due to their relatively low valuations, value stocks
are typically less volatile than growth stocks. In comparison, a growth stock's
price may be more directly linked to market developments than a value stock's
price. However, value stocks tend to have higher dividend yields than growth
stocks. This means they depend less on price changes for returns. Accordingly,
they might not participate in upward market movements, but may be less adversely
affected in a down market compared to lower yielding stocks.

PREFERRED STOCK. Shareholders of preferred stocks normally have the right to
receive dividends at a fixed rate but do not participate in other amounts
available for distribution by the issuer. Dividends on preferred stock may be
cumulative, and cumulative dividends must be paid before common shareholders
receive any dividends. Because preferred stock dividends usually must be paid
before common stock dividends, preferred stocks generally entail less risk than
common stocks. Upon liquidation, preferred stocks are entitled to a specified
liquidation preference, which is generally the same as the par or stated value,
and are senior in right of payment to common stock. Preferred stocks do not
represent a liability of the issuer and, therefore, do not offer as great a
degree of protection of capital or assurance of continued income as investments
in corporate debt securities. In addition, preferred stocks are subordinated in
right of payment to all debt obligations and creditors of the issuer, and
convertible securities may be subordinated to other preferred stock of the same
issuer.

CONVERTIBLE SECURITIES. Convertible securities--also known as
convertibles--include bonds, debentures, notes, preferred stocks, and other
securities. Convertibles are a hybrid security that have characteristics of both
bonds and stocks. Like bonds, they pay interest. Because they can be converted
into common stock within a set period of time, at a specified price or formula,
convertibles also offer the chance for capital appreciation, like common stock.

Convertibles tend to be more stable in price than the underlying common stock,
although price changes in the underlying common stock can affect the
convertible's market value. For example, as an underlying common stock loses
value, convertibles present less opportunity for capital appreciation, and may
also lose value. Convertibles, however, may sustain their value better than the
common stock because they pay income, which tends to be higher than common stock
dividend yields.

Because of this fixed-income feature, convertibles may compete with bonds as a
good source of dependable income. Therefore, if interest rates increase and
"newer," better-paying bonds become more attractive, the value of convertibles
may decrease. Conversely, if interest rates decline, convertibles could increase
in value.

Convertibles tend to be more secure than common stock (companies must generally
pay holders of convertibles before they pay holders of common stock), but they
are typically less secure than similar non-convertible securities such as bonds
(bondholders must generally be paid before holders of convertibles and common
stock). Because convertibles are usually subordinate to bonds in terms of
payment priority, convertibles typically are rated below investment grade by a
nationally recognized rating agency, or they are not rated at all.

WARRANTS. A warrant is a security that gives the holder of the warrant the right
to buy common stock at a specified price for a specified period of time.
Warrants are considered speculative and have no value if they are not exercised
before their expiration date.

ZERO COUPON SECURITIES. Zero coupon securities pay no interest during the life
of the security, and are issued by a wide variety of corporate and governmental
issuers. Certain zero coupon securities are sold at a deep discount.

Zero coupon securities may be subject to greater price changes as a result of
changing interest rates than bonds that make regular interest payments. Their
value tends to grow more during periods of falling interest rates and,
conversely, tends to fall more during periods of rising interest rates than
bonds that make regular interest payments. Although they are not traded on a
national securities exchange, they are widely traded by brokers and dealers, and
are considered liquid. Investors in zero coupon securities are required by
federal income tax laws to pay interest on the payments they would have received
had a payment been made. So, to avoid federal income tax liability, a Fund may
be required to make distributions to shareholders and may

<PAGE>   27

         More About the Funds

have to sell some of its assets at inappropriate times in order to generate cash
to make distributions.

FLOATING AND VARIABLE RATE SECURITIES. Floating- and variable-rate securities
are securities that do not have fixed interest rates; the rates change
periodically. The interest rate on floating-rate securities varies with changes
in the underlying index (such as the Treasury bill rate), while the interest
rate on variable-rate securities changes at preset times based upon an
underlying index. Some of the floating- or variable-rate securities will be
callable by the issuer, which means they can be paid off before their maturity
date.

These securities are subject to interest rate risk like other securities. In
addition, because they may be callable, these securities are also subject to the
risk that they will be repaid prior to their stated maturity and that the repaid
principal will be reinvested in a lower interest rate market, reducing a Fund's
income. A Fund will only purchase floating-and variable-rate securities of the
same quality as the securities it would otherwise purchase.

U.S. GOVERNMENT SECURITIES. These securities include Treasury bills, notes, and
bonds, securities issued or guaranteed by the U.S. Government and securities
issued by U.S. Government agencies, including:

- The Federal Housing Administration, the Farmers Home Administration, and the
  Government National Mortgage Association (GNMA), including GNMA pass-through
  certificates, which are backed by the full faith and credit of the United
  States

- The Federal Home Loan Banks

- The Federal National Mortgage Association (FNMA)

- The Student Loan Marketing Association and Federal Home Loan Mortgage
  Corporation (FHLMC)

- The Federal Farm Credit Banks.

There is virtually no credit risk with U.S. Government securities which are
issued and backed by the "full faith and credit" of the U.S. government (the
U.S. government has the power to tax its citizens to pay these debts). However,
some securities issued by U.S. government agencies are only backed by the
issuing agency, and do contain some credit risk. In addition, neither the U.S.
Government nor its agencies guarantee the market value of their securities, and
interest rate changes, prepayment and other factors may affect the value of
these securities.

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. U.S. Government mortgage-backed
securities are securities that are secured by and paid from a pool of mortgage
loans on real property and issued or guaranteed by the U.S. Government or one of
its agencies. Mortgage-backed securities may also be issued by private issuers.
Collateralized mortgage obligations (CMOs) are securities that have mortgage
loans or mortgage pass-through securities, such as GNMA, FNMA or FHLMC
certificates, as their collateral. CMOs can be issued by U.S. Government
agencies or by private lenders.

These securities are subject to interest rate risk and credit risk if they are
issued by private issuers. CMOs and other mortgage-backed securities are also
subject to prepayment risk. With respect to prepayment risk, when interest rates
fall, homeowners may refinance their loans and the mortgage-backed security will
be paid off sooner than the portfolio manager anticipated. Reinvesting the
returned principal in a lower interest rate market reduces the Fund's income.
Mortgage-backed securities are also subject to extension risk and the
possibility of losing principal as a result of faster than anticipated
prepayments.

Asset-backed securities are securities that are secured by and paid from a pool
of underlying assets, such as automobile installment sales contracts, home
equity loans, property leases and credit card receivables. Asset-backed
securities are generally issued by private issuers.

DERIVATIVES. A derivative is a contract whose value is based on the performance
of an underlying financial asset, index or other investment. For example, an
option is a derivative because its value changes in relation to the performance
of an underlying stock. The value of an option on a futures contract varies with
the value of the underlying futures contract, which in turn varies with the
value of the underlying commodity or security. Derivatives are available based
on the performance of assets, interest rates, currency exchange rates, and
various domestic foreign indexes. Derivatives afford leverage and can also be
used in hedging portfolios.

SOVEREIGN DEBT. Sovereign debt includes:

- Fixed income securities issued or guaranteed by foreign governments and
  governmental agencies

- Fixed income securities issued by government owned, controlled or sponsored
  foreign entities

- Debt securities issued by entities created to restructure the fixed income
  securities issued by any of the above issuers

         MANAGEMENT

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

The following is management's discussion of the performance of the Funds for the
year ended December 31, 1999. This discussion provides an overview of the
economy and how it affected the Funds during the year. It also provides a look
into the current and future investment techniques and strategies of the Funds
from the perspective of the portfolio managers.

STRONG NSAT MID CAP GROWTH FUND.

While international events were the focal point of investors during 1998,
domestic economic fundamentals drove the market in 1999. As the economy and
stock market continued their torrid pace, the Federal Reserve became very vocal
expressing its desire to keep inflation in check. Every release of economic data
was scrutinized for signs of inflation and economic overheating. As a result,
the market had a very bearish tone throughout the year as any negative economic
news generally prompted greater market reaction than did positive news. The Fed
subsequently took back the three easements of 1998, with three tightenings of
0.25% each in 1999.

Much of the market's concern during 1999 was centered around the economy growing
at a rate faster than the so-called sustainable rate. This robust growth and the
economy's ability to create jobs pushed down the unemployment rate to a 29 year
low of 4.1 percent and continued to deplete the pool of available workers to the
consternation of the Fed. The Fed's fear is that this shortage of workers will
ultimately lead to higher wages and an increase in inflation. Thanks largely to
improvements in productivity, excess global capacity, and fierce competition,
this has not yet happened. In fact, observed inflation remains largely in check.
Although the Consumer Price Index through the end of November was up an
annualized 2.7 percent versus a -1.6 percent rate in 1998, this was largely the
result of a surge in energy prices. A more dependable measure of underlying
inflationary pressures is the core rate of inflation, which excludes the energy
and food components. The core rate was up 2.0 percent through November compared
to a 2.3 percent rise in the comparable period in 1998.

The Fund finished 1999 with a strong 84.75% return, compared to the S&P 500
Index return of 21.04%. Our technology, retail, and energy sectors all had
strong performance led by semiconductors, telecommunications, Internet-related
issues, and oil services. An underweighted position in healthcare in the second
quarter and an overweighted position in biotechnology in the fourth quarter also
added to the Fund's performance relative to its benchmark.

The Fund's exposure remains concentrated in selected technology, health care,
financial and energy service companies. The prospects for leading semiconductor
companies continue to improve, driven by the rapid build-out of the Internet,
the need for enhanced transmission capacity (bandwidth), and signs of
accelerating Asian demand. Following a sharp correction in the second quarter,
we have increased our exposure to Internet-related issues, with particular
emphasis on Internet infrastructure beneficiaries. As the "Net" grows in depth
and scope, E-commerce software enablers and companies involved in the expansion
of its infrastructure are likely to prosper.

The growth of the Internet and its acceptance as an important source of
competitive advantage should continue to enhance the prospects of companies
engaged in business to business commerce, wireless connectivity, Internet
content, bandwidth expansion, the building of new brands, and a host of other
applications. The successful implementation of technology remains an essential
source of global competitiveness with superior returns on capital and market
share gains the principal result.

During the next six months, we expect the U.S. economy to continue to grow at a
more moderate pace. We expect the Fed to remain vigilant, poised to nudge
interest rates preemptively higher to offset signs of inflationary pressure. In
our view, companies able to generate unit growth will continue to be the big
winners in this environment. Without pricing, unit growth supports the higher
revenue run rates needed to offset cost pressures.

Our preference is for pure plays in dynamic niche markets, new product cycles,
or innovative new services. As growth investors, our investment team is
constantly on the look out for investments exhibiting sustainable fundamental
improvement regardless of industry in order to consistently outperform the
broader market averages.

NATIONWIDE STRATEGIC VALUE FUND.

The year closed with a flurry as the S&P 500 Index returned 14.88% over the last
three months of the millennium. The quarter more than doubled the return that
the Index posted over the first three quarters of the year bringing the year end
annual return for the Index to 21.04%. A consistent trend throughout the year
was the rise of technology. Market growth and new additions to the Index saw
technology increase as a percentage of the Index to almost one-third of the
total weight.

The sectors that we continue to overweight going into the new year and have
throughout the year are financials, basic materials, and transportation. All of
our individual stock selections in those sectors continue to trade at very low
valuations, and we believe they have solid fundamentals and earnings growth
potential. The sectors leading the way for performance in the Fund to close the
year were technology, health care, and utilities. The Fund outperformed its
benchmark in the utility and health care sectors thanks to a rebound in our
pharmaceutical selections and a strong quarter for the telephone stock BCE Inc.
which rose over 80%. However, the Fund as a whole lagged the Index throughout
the year due to an underweight in technology and a few stocks that struggled
after reporting earnings shortfalls. Our technology underweight was due to
extremely high valuations across many of the industries within the sector.

Generally summarizing the year, the first six months were dominated by a small
group of large growth stocks. The second half of the year was driven by a
technology sector growing at an amazing pace with multiples continuing to rise
to once unheard of levels. We remain convinced that this rough period for value
investors will end, but the timing is uncertain. The position of the Federal
Reserve and its current series of rate hikes needs to be overcome. When it does,
the market should begin to recognize the value of the many fundamentally solid
companies currently being ignored.

Our policy has always been to remain fully invested in common stocks at all
times, and we do not try to predict or "time" the market. The Fund will search
for stocks trading at price/earnings rates less than the S&P average with better
prospects for growth. This is an approach we have maintained since the inception
of the Fund and we will continue to stick to this value approach.

DREYFUS NSAT MID CAP INDEX FUND.

Until September 27, 1999, the Dreyfus NSAT Mid Cap Index Fund was actively
managed and compared against the S&P MidCap 400 Index. Since September 27, 1999,
the Dreyfus NSAT Mid Cap Index Fund has been managed passively to replicate the
middle capitalization U.S. Equity market as represented by the S&P MidCap 400
Index. For the year the Fund outperformed this Index utilizing both management
styles together. Going forward, the Fund utilizes a strategy of full
replication, which entails holding all stocks in the S&P MidCap 400 in direct
proportion to their weight in the index. S&P MidCap 400 depository receipts are
utilized to efficiently manage daily cash flows.

Middle capitalization stocks had a strong performance for 1999. Among the best
performing groups for 1999 were stocks of communication equipment companies and
telephone companies. Among the worst performing groups for 1999 were stocks of
consumer services companies and health distribution companies. The Dreyfus NSAT
Mid Cap Index Fund holds all stocks in direct proportion to their weight in the
Index.

NATIONWIDE SMALL CAP VALUE FUND.

The Nationwide Small Cap Value Fund was up 27.84% for the year ended December
31, 1999. The Russell 2000 Value Index was down 1.49% for the year.

The smaller capitalization market ended another good year on a strong note. The
growth sector, with its large technology component, dramatically outpaced the
value side of the market. Indeed value stocks were essentially flat for the year
while growth stocks were up about 50%. While this performance divergence has
been a persistent characteristic of the market for several years, it was even
more so in 1999.

Our sector focus has not changed significantly for the past several quarters. We
continue to emphasize technology and energy stocks in the portfolio but, unlike
recent quarters, these sectors underperformed their respective benchmarks for
the fourth quarter. Energy prices fluctuated erratically as supply concerns,
induced primarily by threats from producing countries to reduce output,
continued to impact the market. Our portfolio of technology stocks had a
positive return but lagged the Index due to the strong advance of Internet
related companies which are clearly part of the growth investment spectrum.

We are also emphasizing the consumer sectors. The economy continues to grow at a
healthy pace and inflation and unemployment remain low. The continued high level
of consumer confidence should result in strong demand at the retail level.

Utilities and financial services remain underweighted relative to the benchmark.
These sectors should continue to have slow earnings growth and investor
enthusiasm will likely be dampened by interest rate concerns.

While we are disappointed in the quarterly results, we are encouraged by the
large number of attractively priced stocks we are currently finding. We have
continued to emphasize those sectors of the market where we find companies with
good prospects selling at attractive prices. Our focus on the undervalued stocks
with improving business momentum should continue to produce strong results.

NATIONWIDE SMALL CAP GROWTH FUND.

The Nationwide Small Cap Growth Fund began operations at the beginning of May
1999. Since inception, the Fund was up 105.01%. This compares to the Russell
2000 Growth Index, which advanced 33.73% during this time.

After five years of underperformance versus their large cap brethren, small cap
stocks outperformed large caps in 1999. This outperformance was propelled by
technology and other growth stocks in the Russell 2000 Index. The biggest story
within the small cap universe was the differential returns between small cap
growth stocks and small cap value stocks. As measured by the Russell 2000 style
indices, small cap growth stocks gained 42.5% in 1999, whereas small cap value
stocks actually declined 4.0% -- a 46.5% relative outperformance by growth
stocks. Underlying sector performance was quite phenomenal as differences among
sectors easily exceeded 100%. The strongest performing sector was the technology

NATIONWIDE GLOBAL 50 FUND.

Until May 1, 2000, the Nationwide Global 50 Fund was the Nationwide Global
Equity Fund, which was managed by its subadviser as a broadly diversified fund.
The discussion of the Fund's performance included here is for 1999 when this
strategy was being used; the performance of the Fund going forward may be
different because of the Fund's new strategy of investing in a concentrated
portfolio of global equities.

The total return for the Nationwide Global 50 Fund was 22.92% for the year ended
December 31, 1999. The MSCI

World Index returned 24.93% and the Lipper VA Global Funds Average was 44.18%
for the same time period.

PERFORMANCE ANALYSIS

Global equity markets ended 1999 significantly higher, with the technology
sector inspiring much of the rise. This trend was particularly noticeable in the
fourth quarter as the telecommunications and general technology sectors
displayed returns of around 30% against returns of less than 5% in most other
parts of the market. The dominance of the technology sector over the period led
to very narrow markets.

The Fund has been managed in a core, risk controlled style, seeking to add value
versus the benchmark (MSCI World Index), while seeking to control volatility.
The managers identify three sources of added value: country/regional allocation,
stock selection, and currency management.

Over the year, the decision to underweight the U.S. market was beneficial, with
international markets (non-U.S.) finally outperforming. Overall, however,
country allocation was negative for the period, mainly as a result of
overweighting the United Kingdom and underweighting Japan.

Stock selection was positive over the period, with European stock selections
performing particularly strongly. Stock selection in Japan also contributed to
performance. The past year did, however, prove to be difficult for U.S. stock
selection strategy. The dominance of growth stocks detracted from results. In
addition, the Fund was adversely affected by sharp falls in a number of stock
prices following the release of corporate profit news.

The continuing global economic growth is good for world equity markets, as is
the prospect of significant liquidity entering the markets. On the other hand,
we are facing the prospect of a further round of tightening by central banks. We
continue to favor continental Europe, with its strong earnings momentum and
high-predicted levels of merger and acquisition and initial public offering
activity. The Fund is underweighted in the United States, where valuations look
stretched.

FEDERATED NSAT EQUITY INCOME FUND.

After a third quarter correction which began in mid-July and ended in
mid-October, the market enjoyed a very strong performance to complete the year.
Including a rise of 14.88% in the fourth quarter, the S&P 500 Index has just
completed its fifth consecutive year of 20%+ gains. Much like last year,
however, this remarkable performance was attributed to a relatively small number
of stocks. Merrill Lynch reports that just 15 companies provided 100% of the S&P
500's return in 1999. Nearly 60% of the stocks in the index had negative returns
for the year. It was also the second consecutive year in which "growth" stocks
dramatically outperformed "value" stocks. According to Ned Davis Research, Inc.,
large-capitalization growth stocks outperformed large-capitalization value
stocks by 25.9% in 1999.

The Federated NSAT Equity Income Fund had an outstanding year, returning 18.49%
compared to the 3.34% return of the average equity income fund, as reported by
Lipper Analytical Services.

                                       32
<PAGE>   34

This performance has been achieved by consistently choosing market-leading
companies within a strategy of sector weightings similar to that of the S&P 500.
During the late summer/early fall stock market correction, the Fund outperformed
the S&P 500 with its conservative strategy. Income is achieved through the use
of convertible bonds and preferred stocks; further, approximately 30% of the
Fund's holdings are in common stocks which have raised their dividends in at
least each of the last ten years.

The U.S. economy continues to be very strong and international economies are
improving. Such strength has led to inflation fears, as reflected in the rising
yield on the 30-year Treasury bond. The Federal Reserve is expected to increase
short-term interest rates early in the new year, in an effort to cool the
economy and prevent inflation. A "soft landing" with continued low inflation
could allow this longest bull market on record to continue into the new
millennium.

J.P. MORGAN NSAT BALANCED FUND.

The J.P. Morgan NSAT Balanced Fund returned 0.87% for the year ended December
31, 1999 versus a combination of 50% Lehman Brothers Aggregate Bond Index and
50% S&P 500, which returned 9.79%. As of December 31, 1999, the J.P. Morgan NSAT
Balanced Fund was allocated as follows: common stock (56%), investment grade
bonds (34%), high yield securities (6%) and short term securities (4%). The Fund
continues to evolve toward a 40% bond and 60% stock allocation in order to be
similar to most balanced funds. For the quarter ended December 31, 1999 the Fund
under-performed with a return of 0.92% versus 7.22% against the combination 50%
bond index/50% S&P 500 index. The Fund's underperformance for the quarter and
the year is primarily due to an underweighted position in richly valued
technology stocks and a focus on large cap growth names which were mediocre
performers for the year.

Through the quarter, equities were rebalanced in the direction of higher quality
companies in industries perceived to have good long-term growth prospects. At
the end of December, the largest equity holdings in order of size were: IBM,
Anheuser Busch, General Electric, McDonalds, Coca-Cola, and AT&T. The intention
is to position the Fund in equities that can compete against the S&P 500 with an
emphasis on top quality.

The current stock market environment reflects the tug-of-war that often occurs
at inflection points in the economy. The U.S. stock market has benefited from
the ideal combination of a strong domestic economy and low domestic interest
rates, but now must contend with changes that are taking place in the world
economy.

Financial markets are likely to intensify their focus on labor markets in early
2000, following the lead of the Federal Reserve policymakers. Recent Federal
Open Market Committee (FOMC) policy statements have highlighted diminishing
labor market slack due to the imbalance between aggregate supply and demand,
which could prove inflationary. Chairman Greenspan has warned repeatedly of a
shortage of available workers.

Going forward the global economy should enjoy a healthy start in the new
millennium. The medium term outlook for global growth has improved, reflecting
both a higher capacity for growth in the U.S. and evidence that this increased
capacity will spread elsewhere in the industrial world. Nonetheless, the risks
to the outlook remain notable, including widely cited U.S. imbalances that have
surfaced in recent years.

MAS NSAT MULTI SECTOR BOND FUND.

The MAS NSAT Multi Sector Bond Fund returned 1.56% for the twelve month period
ended December 31, 1999 versus the Lehman Brothers Aggregate Bond Index, which
returned -0.83%. The Fund's outperformance for the year relative to the
benchmark can be attributed to its overweighted position in the high yield and
the emerging market debt sectors, which performed relatively well.

The investment grade bond market started 1999 off strong, benefiting from stable
treasury rates, declining volatility, and a reduction in liquidity premiums.
Away from investment grade, performance for high yield bonds and emerging market
debt had a stellar start, as the financial markets shrugged off Brazil's
currency problems. As the year progressed, however, the bond market encountered
some difficulties. Fears of an overheating economy coupled with mounting
investor fear of inflation and Y2K concerns conspired against the fixed income
sector. The mounting inflation concerns forced a proactive Federal Reserve to
raise the Federal Funds rate three times from 4.75% to 5.50%. Inflation risks,
however, still seem uncomfortably high. Dealers took on lower inventories as
they prepared for Y2K, which resulted in an illiquid market.

The Fund continued to rotate within the fixed income sector during the quarter.
Emerging market, high yield and non-U.S. investment grade allocations were
increased. The Fund subsequently lowered its U.S. investment grade exposure.
Going forward, the Fund intends to be more aggressive in adjusting its U.S.
investment grade and emerging markets allocations.

FEDERATED NSAT HIGH INCOME BOND FUND.

High yield bonds generated attractive relative returns for the year, although
absolute returns were held back by the general rise in interest rates and an
increase in default rates. Fourth quarter trends that impacted the market were
consistent with those seen throughout 1999. The high yield market gained its
strength from the continued surge in U.S. economic activity, rebounding foreign
economies, and soaring equity markets. The fourth quarter also benefited from
modest new issue supply, especially when viewed against expectations and an
alleviation of Y2K concerns. The attractive relative returns are illustrated by
the yield spread between high yield bonds and treasury securities which
tightened by approximately 50 basis points during the quarter and 75 basis
points for the year according to the First Boston High Yield Index. These
positives were tempered by a roughly 50 basis point rise in yields on 10-year
U.S. Treasury bonds during the fourth quarter, 175 basis points for the 12-month
period, and continuing high levels of credit downgrades and defaults. We expect
that defaults will top 4% for the first time since 1991. The rise in default
rates despite a strong economy was the result of 1998's decline in energy prices
which impacted many energy companies in early 1999 and the high level of
issuance in the 1996-1998 time period. Historically, there is a correlation
between periods of heavy issuance and defaults on a lagged basis. For the year
as a whole, the Lehman Brothers High Yield Index returned 2.39% versus -0.83%
for the Lehman Brothers Aggregate Bond Index.

The Fund returned 2.57% in the fourth quarter, outperforming the Lehman Brothers
High Yield Bond Index. The Fund is overweighted the B-rated sector, which
outperformed both the more interest rate sensitive BB-rated sector and the more
credit impacted CCC-rated sector. The Fund's overweight in telecommunications
aided performance as this large market sector outperformed the overall market,
especially the wireless sub-segment. Strong performers in telecommunications
include: Telesystems International, Millicom, Winstar, Teligent, and Nextel. The
Fund also benefited from its overweight in cable TV as positions in RCN and UIH
Australia Pacific outperformed the overall market. Other strong performers for
the quarter include: Sterling Chemical, which benefited from better styrene
prices; Regal Cinemas, which exceeded earnings expectations and R&B Falcon,
which benefited from the rebound in oil drilling volume and dayrates. On the
negative side, several positions underperformed based on weak operating
performance. They include: Revlon, Ameriserve, Clark Materials, Dialog, and AEI
Resources.

The Fund returned 3.19% for the full year, outperforming its benchmark. The
B-rated cable TV and telecommunications mentioned above helped performance for
the full year. The Fund also experienced a default rate well below the industry
average which aided performance. The Fund's underweight in the energy sector and
forest product sector hurt full-year performance as those sectors were some of
the strongest performers for the full year.

Looking into 2000, we believe that strong economic growth worldwide coupled with
attractive yield spreads will lead to good relative performance for high yield
bonds. However, possible Fed rate increases to slow the domestic economy may
temper absolute returns. We believe default rates, which increased in 1999 to
their highest level in eight years, will remain above average for the next few
quarters. However, given the high percentage of securities currently trading at
distressed levels, the performance impact of these defaults has, to some degree,
already been felt.

From a portfolio perspective, we continue to like the telecommunications sector,
as strong operating gains and consolidation activity provide opportunities for
strong relative returns. We also think that cable TV plant upgrades in both the
U.S. and western Europe will lead to strong performance by fund holdings in
companies such as United International, United Pan-European, NTL, and Charter
Communications. We also believe that specific fund holdings in healthcare and
chemicals, which underperformed in 1999, are poised to rebound in 2000.

INVESTMENT MANAGEMENT

Investment Adviser

Villanova Mutual Fund Capital Trust (VMF), 1200 River Road, Conshohocken, PA
19428, manages the investment of the assets and supervises the daily business
affairs of the Nationwide Separate Account Trust (the Trust). Subject to the
supervision and direction of the Trustees, VMF also determines the allocation of
Fund assets among the subadvisers and evaluates and monitors the performance of
the subadvisers. VMF is also authorized to select and place portfolio
investments on behalf of a Fund; however, VMF does not intend to do so at this
time. VMF was organized in 1999 and manages mutual fund assets. As of August 31,
2000, VMF and its affiliates had approximately $24.2 billion in assets under
management.

Each Fund pays VMF a management fee, which is based on the Funds' average daily
net assets. The total fee paid by each of the Funds for the fiscal year ended
December 31, 1999 -- expressed as a percentage of each Fund's average daily net
assets--was as follows:

Multi-Management Structure

VMF and the Trust have received from the Securities and Exchange Commission an
exemptive order for a multi-manager structure that allows VMF to hire, replace
or terminate subadvisers without the approval of shareholders. The order also
allows VMF to revise a subadvisory agreement with Trustee approval but without
shareholder approval. If a new subadviser is hired, shareholders will receive
information about the new subadviser within 90 days of the change. The order
allows the Funds to operate more efficiently and with greater flexibility.

VMF provides the following oversight and evaluation services to the Funds:

- performing initial due diligence on prospective subadvisers for the Funds

- monitoring the performance of the subadvisers through ongoing analysis, as
  well as periodic consultations

- communicating performance expectations and evaluations to the subadvisers

- ultimately recommending to the Board of Trustees whether a subadviser's
  contract should be renewed, modified or terminated.

VMF does not expect to recommend frequent changes of subadvisers. VMF will
periodically provide written reports to the Board of Trustees regarding the
results of its evaluation and monitoring functions. Although VMF will monitor
the performance of the subadvisers, there is no certainty that any subadviser or
Fund will obtain favorable results at any given time.

The Subadvisers. Subject to the supervision of VMF and the Trustees, a
subadviser will manage all or a portion of a Fund's assets in accordance with a
Fund's investment objective and strategies. With regard to the portion of the

Although the Funds have been operating for only a limited time, some of the
subadvisers have managed similar mutual funds or institutional accounts for a
longer period. These other mutual funds or institutional accounts have
investment objectives and strategies that are substantially similar, but not
necessarily identical, to those of the Funds. We have included performance
information about these other mutual funds or institutional accounts for
comparison purposes, BUT THESE OTHER MUTUAL FUNDS AND INSTITUTIONAL ACCOUNTS ARE
SEPARATE AND DISTINCT FROM EACH FUND. THEIR PERFORMANCE DOES NOT GUARANTEE
SIMILAR RESULTS FOR A FUND AND SHOULD NOT BE VIEWED AS A SUBSTITUTE FOR A FUND'S
OWN PERFORMANCE.

If you purchase a Fund through a variable annuity contract or a variable life
insurance policy, you will also be subject to charges relating to these
contracts or policies. Both the performance for the Funds listed above and the
subadviser performance included below do not reflect these charges, which would
reduce the your total return. Therefore, these performance figures are only of
limited use for comparative purposes.
------------

(1) The performance for these Funds covers a period (a partial period for the
    Dreyfus NSAT Mid Cap Index Fund) when a different subadviser managed the
    Fund or the Fund was managed in a different style.

(2) The Small Cap Growth Fund began operations on May 1, 1999, and has less than
    one year of performance.

         Management

The performance of similar mutual funds or institutional accounts managed by the
subadvisers may not be comparable to the performance of a Fund because of the
following differences:

- brokerage commissions and dealer spreads

- expenses (including management fees)

- the size of the investment in a particular security in relation to the
  portfolio size

- the timing of purchases and sales (including the affect of market conditions
  at that time)

- the timing of cash flows into the portfolio

- the availability of cash for new investments.

If the historical performance relates only to institutional accounts (including
institutional accounts that are included in composite performance), the
performance may not be comparable to the performance of the Funds because,
unlike the Funds, the institutional accounts may not be required to do the
following:

- redeem shares upon request

- meet the same diversification requirements as mutual funds

- follow the same tax restrictions and investment limitations as mutual funds.

In some instances the performance of the institutional accounts is calculated by
combining the performance of all similarly managed accounts into a composite.
Depending on the subadviser, the composite may or may not also contain
registered mutual funds. If the accounts within each composite had been subject
to all Fund expenses, their performance may have been lower. As indicated below,
the composite performance may be prepared in compliance with the Performance
Presentation Standards of the Association for Investment Management and Research
(AIMR Standards), which are different from the performance methodology used by
registered investment companies like the Funds. AIMR has not been involved with
the preparation or review of this information.

Average annual total return represents the average change over a specified
period of time in the value of an investment after reinvesting all income and
capital gains distributions.

Historical performance information has been provided by the following
Subadvisers: Strong, Schafer, J.P. Morgan and Federated. The Funds believe that
it is reliable, but the Funds have not independently verified it.

STRONG CAPITAL MANAGEMENT, INC. Strong is the subadviser for the Strong NSAT Mid
Cap Growth Fund. The following chart shows the average annual total returns of
the Strong Growth Fund. Strong manages this fund in a manner substantially
similar to the way it manages the Strong NSAT Mid Cap Growth Fund. The
historical investment performance of the Strong Growth Fund reflects the
deduction of total annual operating expenses of 1.24% as of December 31, 1999,
which are higher than the total operating expenses of the Strong NSAT Mid Cap
Growth Fund before fee waivers.

J.P. MORGAN INVESTMENT MANAGEMENT INC. J.P. Morgan is the subadviser for the
J.P. Morgan NSAT Balanced Fund. The following chart shows the average annual
total returns of the J.P. Morgan Balanced Commingled Account Composite. Each of
the accounts in this composite is managed by J.P. Morgan in a manner
substantially similar to the way it manages the J.P. Morgan NSAT Balanced Fund.
The historical investment performance of the composite reflects the deduction of
a 0.60% advisory fee, which is the maximum fee charged by J.P. Morgan for
accounts in the composite, but does not include the deduction of custody fees,
which vary by account. These fees are lower than the total annual operating
expenses of the J.P. Morgan NSAT Balanced Fund before fee waivers. J.P. Morgan
prepared this performance in compliance with AIMR Standards.

         BUYING AND SELLING FUND SHARES

WHO CAN BUY SHARES OF THE FUNDS

Shares of the Funds are currently sold to separate accounts of Nationwide Life
Insurance Company and its wholly owned subsidiary, Nationwide Life and Annuity
Insurance Company, to fund benefits payable under variable life insurance
policies and variable annuity contracts. Shares of the Funds may also be sold to
affiliated Funds of Funds, and may in the future be sold to other insurance
companies. Shares are not sold to individual investors.

The separate accounts purchase shares of a Fund in accordance with variable
account allocation instructions received from owners of the variable annuity
contracts or variable life insurance policies. A Fund then uses the proceeds to
buy securities for its portfolio.

Because variable annuity contracts or variable life insurance policies may have
different provisions with respect to the timing and method of purchases,
exchanges and redemptions, contract or policy owners should contact their
insurance company directly for details concerning these transactions.

Please check with your insurance company to determine which Funds are available
under your variable annuity contract or variable life insurance policy. This
prospectus should be read in conjunction with the prospectus of the separate
account of your specific insurance product.

Each Fund sells its shares to separate accounts of both Nationwide Life
Insurance Company and Nationwide Life and Annuity Insurance Company and may sell
its shares to separate account of other unaffiliated insurance companies. The
Funds currently do not foresee any disadvantages to the owners of variable
annuity contracts or variable life insurance products arising out of the fact
that the Funds may offer their shares to the separate accounts of various
insurance companies to fund benefits of these variable insurance products.
Nevertheless, the Trustees intend to monitor events in order to identify any
material irreconcilable conflicts which may arise, and to determine what action,
if any, should be taken in response to such conflicts. If such a conflict were
to occur, one or more insurance companies' separate accounts might be required
to withdraw their investments in one or more Funds and shares of another Fund
may be substituted. This might force a Fund to sell its securities at
disadvantageous prices.

PURCHASE PRICE

The purchase price of each share of a Fund is its "net asset value" (or NAV)
next determined after the order is received. No sales charge is imposed on the
purchase of a Fund's shares. Generally, NAV is determined by dividing the total
market value of the securities owned by a Fund, less its liabilities, by the
total number of its outstanding shares. NAV is determined at the close of
regular trading on the New York Stock Exchange (usually 4 p.m. Eastern Time) on
each day the Exchange is open for trading.

The Funds do not determine NAV on the following days:

- Christmas Day

- New Year's Day

- Martin Luther King Jr. Day

- Presidents' Day

- Good Friday

- Memorial Day

- Independence Day

- Labor Day

- Thanksgiving Day

- other days when the New York Stock Exchange is not open.

The Funds reserve the right not to determine NAV when:

- a Fund has not received any orders to purchase, sell, or exchange shares

- changes in the value of a Fund's portfolio do not affect the NAV.

If current prices are not available for a security, or if Villanova SA Capital
Trust (VSA), as the Fund's administrator or its agent determines that the price
of a security does not represent its fair value, the security may be valued at
fair value in accordance with procedures adopted by the Board of Trustees. To
the extent that a Fund's investments are traded in markets that are open when
the New York Stock Exchange is closed, the value of the Fund's investments may
change on days when shares cannot be purchased or redeemed.

SELLING SHARES

Shares may be sold (redeemed) at any time, subject to certain restrictions. The
redemption price is the NAV next determined after the order is received. Of
course, the value of the shares sold may be more or less than their original
purchase price depending upon the market value of a Fund's investments at the
time of sale.

RESTRICTIONS ON SALES

Shares of a Fund may not be redeemed or a Fund may delay paying the proceeds
from a redemption when the New York Stock Exchange is closed (other than
customary weekend and holiday closings) or if trading is restricted or an
emergency exists.

                                       42
<PAGE>   44

DIVIDENDS AND DISTRIBUTIONS

Substantially all of a Fund's net investment income, if any, will be paid as a
dividend each quarter in the form of additional shares of the Fund. Any net
capital gains realized by a Fund from the sale of its portfolio securities will
be declared and paid to shareholders annually.

TAX STATUS

The tax treatment of payments made under a variable annuity contract or variable
life insurance policy is described in the prospectus for the contract or policy.
Generally, the owners of variable annuity contracts and variable life insurance
policies are not taxed currently on income or gains realized under such
contracts until the income or gain is distributed. However, income distributions
from these contracts and policies will be taxable at ordinary income tax rates.
In addition, distributions made to an owner who is younger than 59 1/2 may be
subject to a 10% penalty tax. Investors should ask their own tax advisors for
more information on their own tax situation, including possible state or local
taxes.

Please refer to the Statement of Additional Information for more information
regarding the tax treatment of the Funds.

         FINANCIAL HIGHLIGHTS

The financial highlights tables are intended to help you understand the Funds'
financial performance for the period of the Funds' operations. Certain
information reflects financial results for a single Fund share. The total
returns in the tables represent the rate that an investor would have earned (or
lost) on an investment in the Funds, assuming reinvestment of all dividends and
distributions. This information has been audited by PricewaterhouseCoopers LLP,
whose report, along with the Funds' financial statements, is included in the
annual report, which is available upon request.

         FUND SUMMARIES -- GARTMORE NSAT GLOBAL TECHNOLOGY
                           AND COMMUNICATIONS FUND
This section summarizes key information about the Funds. Use these summaries to
compare the Funds with other mutual funds. More detailed information about the
risks and investment techniques of the Funds can be found in "More About the
Funds" beginning on page seven.

OBJECTIVE

The Fund seeks long term capital appreciation. The Fund's investment objective
may be changed without shareholder approval.

PRINCIPAL STRATEGIES

The Fund invests primarily, and at least 65% of its total assets, in equity
securities issued by U.S. and foreign companies with business operations in
technology and communications and technology and communications related
industries. These companies may include, for example, companies that develop,
produce and distribute products or services in the computer, semi-conductor,
electronics, communications, health care, and biotechnology sectors. A security
will generally be considered appropriate if (as determined by the investment
adviser) at least 50% of the issuer's assets, revenues, or net income is related
to, or derived from, the industry or industries designated for the Fund.

TECHNOLOGY:
The use of science to create new products and services. The industry comprises
information technology and communications as well as medical, environmental and
biotechnology.

The Fund may invest in companies domiciled in any country and allocates its
assets among securities that are expected to provide the best opportunities for
meeting its investment objective. However, normally at least 65% of its total
assets will be invested in companies in at least three different countries, one
of which may be the U.S. If the portfolio manager thinks that advantageous
investment opportunities exist in countries with emerging securities markets,
the Fund will invest in those countries.

The Fund may invest in companies of any size. The Fund may invest in securities
of large companies that are well established in the world technology market
because they can be expected to grow with the market. The Fund may also invest
in securities of small to mid-size companies to the extent that they provide
strong prospects for future growth.

In analyzing specific companies for possible investment, the Fund's portfolio
manager ordinarily looks for several of the following characteristics:

  - Above-average per share earnings growth

  - High return on invested capital

  - A healthy balance sheet

  - Sound financial and accounting policies and overall financial strength

  - Strong competitive advantages

  - Effective research and product development and marketing

  - Development of new technologies

  - Efficient service

  - Pricing flexibility

  - Strong management

  - General operating characteristics that will enable the company to compete
    successfully in its respective markets

The portfolio manager considers whether to sell a particular security when any
of those factors materially changes.

The Fund may also lend portfolio securities on a short-term or long-term basis
up to 30% of its total assets. The Investment Adviser expects a high portfolio
turnover rate of 300% or more.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the portfolio manager's ability to assess economic
conditions and investment opportunities.

STOCK MARKET RISK. Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. Stock markets are affected by
numerous factors, including interest rates, the outlook for corporate profits,
the health of the national and world economies, national and world social and
political events, and the fluctuations of other stock markets around the world.

RISKS RELATED TO INVESTING FOR GROWTH. Different types of stocks tend to shift
into and out of favor with stock market investors depending on market and
economic conditions. Because the Fund focuses on growth-style stocks, the Fund's

                                        3

                  and Communications Fund

performance may at times be better or worse than the performance of stock funds
that focus on other types of stocks, or that have a broader investment style.

SMALL CAP RISK. The Fund's investments in smaller, newer companies may be
riskier than investments in larger, more established companies. The stocks of
smaller companies are usually less stable in price and less liquid than the
stocks of larger companies.

FOREIGN RISK. Investments in foreign securities involve risks in addition to
those of U.S. investments. These risks include political and economic risks,
currency fluctuations, higher transaction costs, and delayed settlement. To the
extent that the Fund invests in countries with emerging markets, the foreign
securities risks are magnified since these countries may have unstable
governments and less established markets.

SECTOR RISK. The Fund may be susceptible to factors affecting technology and
communications and technology-and communications-related industries and
therefore the value of the Fund's investments may be more volatile than other
funds that invest in a broader range of securities across different industries.

PORTFOLIO TURNOVER RISK. The Fund will attempt to buy securities with the intent
of holding them for investment, but the subadviser may engage in active and
frequent trading of securities if doing so is in the best interest of the Fund.
A higher portfolio turnover rate may result in higher transaction costs for the
Fund and increase the volatility of the Fund.

(1) Sales charges and other expenses may be imposed by variable annuity
    contracts or variable life insurance policies if the Fund's shares are
    purchased by a life insurance separate account as an investment option for
    these contracts or policies.

(2) The Fund commenced operations on July 3, 2000. As a result, the management
    fee represents the fee which is payable to the adviser under its contract
    with the Fund.

(3) As a new fund these are estimates for the current fiscal year ending in
    December 31, 2000. These estimates do not take into account the expense
    limitation agreement between the Fund and the adviser.

(4) For the fiscal year ending December 31, 2000, the adviser has agreed to
    waive management fees and, if necessary, to reimburse the Fund for the cost
    of "Other Expenses" so that Total Annual Fund Operating Expenses will not
    exceed 1.35%. The Fund is authorized to reimburse the adviser for management
    fees previously waived and/or for the cost of Other Expenses paid by the
    adviser provided that any such reimbursement will not cause the Fund to
    exceed the expense limitations noted above. The Fund's ability to reimburse
    the adviser in this manner only applies to fees paid or reimbursements made
    by the adviser at some time within the first five years from the time the
    Fund commenced operations.

    The expense limitation agreement has an initial term of one year and
    continues automatically for successive one year terms, provided that the
    Board approves such additional terms.

EXAMPLE

This example shows what you could pay in expenses over time. You can also use
this example to compare the cost of this Fund with other mutual funds.

The example assumes that you invest $10,000 in the Fund for the time periods
indicated and then sell all of your shares at the end of those periods. It
assumes a 5% return each year and no changes in expenses and does not take into
account the fee waiver/expense reimbursement provisions currently in place for
the Fund. Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

FUND SUMMARIES -- TURNER NSAT GROWTH FOCUS FUND

OBJECTIVE

The Fund seeks long term capital appreciation. The Fund's investment objective
may be changed without shareholder approval.

PRINCIPAL STRATEGIES

Villanova Mutual Fund Capital Trust (VMF), the Fund's investment adviser, has
chosen Turner Investment Partners, Inc. as a subadviser to manage the Fund's
portfolio on a day-to-day basis. To achieve its objective, the Fund invests
primarily in U.S. common stocks, ADRs and foreign companies that demonstrate
strong earnings growth potential. The subadviser generally intends to be fully
invested in these securities. The Fund may invest in equity securities of
companies of any size regardless of market capitalization, industry, sector or
country of organization: therefore, it may invest in both older, more
well-established companies and in smaller, emerging growth companies. The Fund
is non-diversified and typically focuses its investments in a core group of 20
to 30 common stocks. By investing in different industries and capitalization
ranges, the subadviser seeks to reduce the Fund's overall level of volatility.
Ideally, when one area of the economy or capitalization range is out of favor,
the other ranges will offer a counterbalancing influence.

Market capitalization is a common way to measure the size of a company based on
the price of its common stock; it's simply the number of outstanding shares of
the company multiplied by the current share price. [Inset Box]

Due to its investment strategy, the Fund may buy and sell securities frequently.
This may result in higher transaction costs.

PRINCIPAL RISKS

Because the value of an investment will fluctuate, there is the risk that a
shareholder will lose money. A shareholder's investment will decline in value if
the value of the Fund's investments decreases. The value of shares will also be
impacted in part by the subadviser's ability to assess economic conditions and
investment opportunities.

STOCK MARKET RISK.  Stock market risk is the risk that the Fund could lose value
if the individual stocks in which the Fund has invested or the overall stock
market goes down. Individual stocks and the overall stock market may experience
short-term volatility as well as extended periods of decline or little growth.
Individual stocks are affected by factors such as corporate earnings,
production, management and sales. Individual stocks may also be affected by the
demand for a particular type of stock, such as growth stocks or the stocks of
companies with a particular market capitalization. The stock market is affected
by numerous factors, including interest rates, the outlook for corporate
profits, the health of the national and world economies, national and world
social and political events, and the fluctuations of other stock markets around
the world.

SMALL CAP RISK.  The Fund's investments in smaller, newer companies may be
riskier than investments in larger, more established companies. The stocks of
small capitalization companies are usually less stable in price and less liquid
than the stocks of larger companies.

NON-DIVERSIFIED FUND RISK.  The Fund is non-diversified. In other words, it may
hold larger positions in a smaller number of securities than a diversified fund.
Since the Fund normally concentrates in a core portfolio of 20 to 30 stocks,
this risk may be increased. As a result, a single security's increase or
decrease in value may have a greater impact on the Fund's net asset value and
total return.

FOREIGN RISK. Investments in foreign securities involve risks in addition to
those of U.S. investments. These risks include political and economic risks,
currency fluctuations, higher transaction costs, and delayed settlement.

RISKS RELATED TO INVESTING FOR GROWTH. Different types of stocks tend to shift
into and out of favor with stock market investors depending on market and
economic conditions. Because the Fund focuses on growth-style stocks, the Fund's
performance may at times be better or worse than the performance of stock funds
that focus on other types of stocks, or that have a broader investment style.

PORTFOLIO TURNOVER RISK. The Fund will attempt to buy securities with the intent
of holding them for investment, but the subadviser may engage in active and
frequent trading of securities if doing so is in the best interest of the Fund.
A higher portfolio turnover rate may result in higher transaction costs for the
Fund and increase the volatility of the Fund. In addition, a high portfolio
turnover rate may have tax implications. Specifically, a high portfolio turnover
rate may increase the portion of the Fund's capital gains that are realized for
tax purposes. This may increase the Fund's taxable dividends in that year.

About the Funds" beginning on page seven.

         MORE ABOUT THE FUNDS

RISKS AND TECHNIQUES

The Funds may use the principal investment techniques to increase returns,
protect assets or diversify investments. These techniques are subject to certain
risks. For additional information about the Funds' investment strategies and
techniques, see the Statement of Additional Information (SAI).

PRINCIPAL RISKS

SMALL CAP RISK.  Historically, the securities of small cap companies have been
more volatile in price than larger company securities, especially over the short
term. Among the reasons for the greater price volatility are the less certain
growth prospects of small companies, the lower degree of liquidity in the
markets for such securities, the greater impact caused by changes in investor
perception of value, and the greater sensitivity of small cap companies to
changing economic conditions. In addition, small cap companies may:

  - lack depth of management

  - lack a proven track record

  - be unable to generate funds necessary for growth or development

  - be developing or marketing new products or services for which markets are
    not yet established and may never become established

  - market products or services which may become quickly obsolete.

Small cap companies in the technology and biotechnology industries may be
subject to abrupt or erratic price movements. Therefore, while small cap
companies may offer greater opportunities for capital growth than larger, more
established companies, they also involve greater risks and should be considered
speculative.

FOREIGN RISK.  Foreign security investment involves special risks not present in
U.S. investments that can increase the chances that a Fund will lose money.

  - COUNTRY.  General securities market movements in any country in which a Fund
    has investments, are likely to affect the value of a Fund's securities that
    trade in that country. These movements will affect a Fund's share price and
    a Fund's performance. The political, economic and social structures of some
    countries in which a Fund invests may be less stable and more volatile than
    those in the U.S. The risks of investing in these countries include the
    possibility of the imposition of exchange controls, currency devaluations,
    foreign ownership limitations, expropriation, restrictions on removal of
    currency or other assets, nationalization of assets, punitive taxes and
    certain custody and settlement risks.

  - FOREIGN MARKETS.  The Fund is subject to the risk that because there are
    generally fewer investors in foreign markets and a smaller number of
    securities traded each day, it may make it difficult for the Fund to buy and
    sell certain securities. In addition, prices of foreign securities may go up
    and down more than prices of securities traded in the U.S. Also, brokerage
    commissions and other costs of buying and selling securities often are
    higher in foreign countries than they are in the United States. This reduces
    the amount the Fund can earn on its investments.

  - GOVERNMENTAL SUPERVISION AND REGULATION/ACCOUNTING STANDARDS.  Foreign
    companies are not subject to the same disclosure, accounting, auditing and
    financial reporting standards and practices as U.S. companies. The Fund may
    have greater difficulty voting proxies, exercising shareholder rights,
    pursuing legal remedies and obtaining judgments with respect to foreign
    investments in foreign courts than with respect to U.S. companies in U.S.
    courts. Many foreign governments supervise and regulate stock exchanges,
    brokers and the sale of securities less than the U.S. does. Other countries
    may not have laws to protect investors the way that the U.S. securities laws
    do. Accounting standards in other countries are not necessarily the same as
    in the U.S. If the accounting standards in another country do not require as
    much detail as U.S. accounting standards, it may be harder for a Fund's
    portfolio manager to completely and accurately determine a company's
    financial condition.

  - COMPANY.  Foreign companies are not subject to the same disclosure,
    accounting, auditing and financial reporting standards and practices as U.S.
    companies and their securities may not be as liquid as securities of similar
    U.S. companies. Foreign stock exchanges, trading systems, brokers and
    companies generally have less government supervision and regulation than in
    the U.S. A Fund may have greater difficulty voting proxies, exercising
    shareholder rights, pursuing legal remedies and obtaining judgments with
    respect to foreign investments in foreign courts than with respect to U.S.
    companies in U.S. courts.

         MORE ABOUT THE FUNDS

  - CURRENCY.  Some of a Fund's investments may be denominated in foreign
    currencies. Changes in foreign currency exchange rates will affect the value
    of what a fund owns and a Fund's share price. Generally, when the U.S.
    dollar rises in value against a foreign currency, an investment in that
    country loses value because that currency is worth fewer U.S. dollars.
    Devaluation of currency by a country's government or banking authority also
    has a significant impact on the value of any securities denominated in that
    currency. In addition, if the currency in which a Fund receives dividends,
    interest or other payments declines in value against the U.S. dollar before
    such income is distributed as dividends to shareholders or converted to U.S.
    dollars, the Fund may have to sell portfolio securities to obtain sufficient
    cash to pay such dividends.

  - EUROPEAN ECONOMIC AND MONETARY UNION (EMU).  A number of European countries
    have entered into EMU in an effort to reduce trade barriers between
    themselves and eliminate fluctuations in their currencies. EMU has
    established a single European currency (the euro), which was introduced in
    January 1, 1999 and is expected to replace the existing national currencies
    of all initial EMU participants by July 1, 2002. Certain securities
    (beginning with government and corporate bonds) were redenominated in the
    euro. These securities trade and make dividend and other payments only in
    euros. Like other investment companies and business organizations, including
    the companies in which the Funds invest, the Fund could be adversely
    affected:

    - If the transition to euro, or EMU as a whole, does not proceed as planned.

    - If a participating country withdraws from EMU.

    - If the computing, accounting and trading systems used by a Fund's service
      providers, or by other entities with which the fund or its service
      providers do business, are not capable of recognizing the euro as a
      distinct currency.

OTHER INVESTMENT TECHNIQUES

PREFERRED STOCK.  Holders of preferred stocks normally have the right to receive
dividends at a fixed rate but do not participate in other amounts available for
distribution by the issuer. Dividends on preferred stock may be cumulative, and
cumulative dividends must be paid before common shareholders receive any
dividends. Because preferred stock usually must be paid before common stock
dividends, preferred stocks generally entail less risk than common stocks. Upon
liquidation, preferred stocks are entitled to a specified liquidation
preference, which is generally the same as the par or stated value, and are
senior in right of payment to common stock. Preferred stocks do not represent a
liability of the issuer and, therefore do not offer as great a degree of
protection of capital or assurance of continued income as investments in
corporate debt securities. In addition, preferred stocks are subordinated in
right of payment to all debt obligations and creditors of the issuer, and
convertible securities may be subordinated to other preferred stock of the same
issuer.

CONVERTIBLE SECURITIES.  Convertible securities -- also known as convertibles --
include bonds, debentures, notes, preferred stocks, and other securities.
Convertibles are a hybrid security that have characteristics of both bonds and
stocks. Like bonds, they pay interest. Because they can be converted into common
stock within a set period of time, at a specified price or formula, convertibles
also offer the chance for capital appreciation, like common stocks.

Convertibles tend to be more stable in price than the underlying common stock,
although price changes in the underlying common stock can affect the
convertible's market value. For example, as an underlying common stock loses
value, convertibles present less opportunity for capital appreciation, and may
also lose value. Convertibles, however, may sustain their value better than the
common stock because they pay income, which tends to be higher than common stock
dividend yields.

Because of this fixed-income feature, convertibles may compete with bonds as a
good source of dependable income. Therefore, if interest rates increase and
"newer," better-paying bonds become more attractive, the value of convertibles
may decrease. Conversely, if interest rates decline, convertibles could increase
in value.

Convertibles tend to be more secure than common stock (companies must generally
pay holders of convertibles before they pay holders of common stock), but they
are typically less secure than similar non-convertible securities such as bonds
(bondholders must generally be paid before holders of convertibles and common
stock). Because convertibles are usually subordinate to bonds in terms of
payment priority, convertibles typically are rated below investment grade by a
nationally recognized rating agency, or they are not rated at all.

WARRANTS.  A warrant is a security that gives the holder of the warrant the
right to buy common stock at a specified

                                        8
<PAGE>   60

price for a specified period of time. Warrants are considered speculative and
have no value if they are not exercised before their expiration date.

DERIVATIVES.  A derivative is a contract whose value is based on the performance
of an underlying financial asset, index or other investment. For example, an
option is a derivative because its value changes in relation to the performance
of an underlying stock. The value of an option on a futures contract varies with
the value of the underlying futures contract, which in turn varies with the
value of the underlying commodity or security. Derivatives are available based
on the performance of assets, interest rates, currency exchange rates, and
various domestic foreign indexes. Derivatives afford leverage and can also be
used in hedging portfolios.

SHORT SALES. In selling a stock which the Fund does not own (a short sale), the
Fund may borrow the security sold short to make delivery to the buyer. The Fund
must then replace the security it has borrowed. If the price of a security sold
short goes up between the time of the short sale and the time the Fund must
deliver the security to the lender, the Fund will incur a loss. The Fund must
also pay the lender any interest accrued during the period of the loan.

TEMPORARY DEFENSIVE POSITIONS

In response to economic, political or unusual market conditions, each Fund may
invest up to 100% of its assets in cash or money market obligations. Should this
occur, a Fund may not meet its investment objectives, and may miss potential
market upswings.

MANAGEMENT

INVESTMENT ADVISER

Villanova Mutual Fund Capital Trust (VMF), 1200 River Road, Conshohocken, PA
19428, manages the investment of the Funds' assets and supervises the daily
business affairs of the Funds. VMF was organized in 1999 and advises mutual
funds. As of August 31, 2000, VMF and its affiliates had approximately $24.2
billion in assets under management.

For the Turner NSAT Growth Focus Fund, VMF also determines the allocation of
Fund assets among one or more subadvisers and evaluates and monitors the
performance of the subadvisers. VMF is also authorized to select and place
portfolio investments on behalf of this Fund; however, VMF does not intend to do
so at this time.

Each Fund pays VMF a management fee as set forth below. The management fee is
based on the Fund's average daily net assets.

For the Turner NSAT Growth Focus Fund, the management fee given above is a base
fee which may be adjusted upward or downward depending on the Fund's performance
relative to its benchmark, the Russell 1000 Growth Index. If the Fund
outperforms its benchmark by a set amount, the Fund will pay higher management
fees. Conversely, if the Fund underperforms its benchmark by a set amount, the
Fund will pay lower fees. The Fund's SAI contains detailed information about any
possible performance based adjustments to the management fees.

PORTFOLIO MANAGER -- GARTMORE NSAT GLOBAL TECHNOLOGY AND COMMUNICATIONS FUND

Aaron Harris is the portfolio manager for the Gartmore NSAT Global Technology
and Communications Fund. Prior to joining VMF in April 2000, Mr. Harris was
portfolio manger for the Nicholas-Applegate Global Technology Fund from 1998-
March, 2000 and was an investment analyst in Global Research at
Nicholas-Applegate from 1995-1997.

SUBADVISER -- TURNER NSAT GROWTH FOCUS FUND

Multi-Management Structure. VMF and the Trust have received from the Securities
and Exchange Commission an exemptive order for a multi-manager structure that
allows VMF to hire, replace or terminate subadvisers without the approval of
shareholders. The order also allows VMF to revise a subadvisery agreement with
Trustee approval but without shareholder approval. If a new subadviser is hired,
shareholders will receive information about the new subadviser within 90 days of
the change. The order allows the Fund to operate more efficiently and with
greater flexibility.

VMF provides the following oversight and evaluation services to the Fund:

  - performing initial due diligence on prospective subadviser for the Fund

  - monitoring the performance of the subadviser through ongoing analysis, as
    well as periodic consultations

  - communicating performance expectations and evaluations to the subadviser

  - ultimately recommending to the Board of Trustees whether a subadviser's
    contract should be renewed, modified or terminated.

VMF does not expect to recommend frequent changes of subadvisers. VMF will
periodically provide written reports to the Board of Trustees regarding the
results of its evaluation and monitoring functions. Although VMF will monitor
the performance of the subadvisers, there is no certainty that the subadviser or
Fund will obtain favorable results at any given time.

The Subadviser. Subject to the supervision of VMF and the Trustees, a subadviser
will manage the Fund's assets in accordance with a Fund's investment objective
and strategies. The subadviser makes investment decisions for the Fund and, in
connection with such investment decisions, places purchase and sell orders for
securities.

Turner Investment Partners, Inc. (Turner), 1235 Westlakes Drive, Suite 350,
Berwyn PA 19312-2414, an SEC-registered adviser, serves as the subadviser to the
Turner NSAT Growth Focus Fund. Turner, which was founded in 1990, serves as
investment adviser to other investment companies, as well as other separate
investment portfolios.

As of September 30, 2000, Turner had approximately $12 billion in assets under
management.

         BUYING AND SELLING FUND SHARES

WHO CAN BUY SHARES OF THE FUNDS

Shares of the Funds are currently sold to separate accounts of Nationwide Life
Insurance Company and its wholly owned subsidiary, Nationwide Life and Annuity
Insurance Company, to fund benefits payable under variable life insurance
policies and variable annuity contracts. Shares of the Funds may also be sold to
affiliated Funds of Funds, and may in the future be sold to other insurance
companies. Shares are not sold to individual investors.

The separate accounts purchase shares of a Fund in accordance with variable
account allocation instructions received from owners of the variable annuity
contracts or variable life insurance policies. A Fund then uses the proceeds to
buy securities for its portfolio.

Because variable annuity contracts or variable life insurance policies may have
different provisions with respect to the timing and method of purchases,
exchanges and redemptions, contract or policy owners should contact their
insurance company directly for details concerning these transactions.

Please check with your insurance company to determine which Funds are available
under your variable annuity contract or variable life insurance policy. This
prospectus should be read in conjunction with the prospectus of the separate
account of your specific insurance product.

Each Fund sells its shares to separate accounts of both Nationwide Life
Insurance Company and Nationwide Life and Annuity Insurance Company and may sell
its shares to separate account of other unaffiliated insurance companies. The
Funds currently do not foresee any disadvantages to the owners of variable
annuity contracts or variable life insurance products arising out of the fact
that the Funds may offer their shares to the separate accounts of various
insurance companies to fund benefits of these variable insurance products.
Nevertheless, the Trustees intend to monitor events in order to identify any
material irreconcilable conflicts which may arise, and to determine what action,
if any, should be taken in response to such conflicts. If such a conflict were
to occur, one or more insurance companies' separate accounts might be required
to withdraw their investments in one or more Funds and shares of another Fund
may be substituted. This might force a Fund to sell its securities at
disadvantageous prices.

PURCHASE PRICE

The purchase or "offering" price of each share of a Fund is its "net asset
value" (NAV) next determined after the order is received. No sales charge is
imposed on the purchase of a Fund's shares. Generally, NAV of a Fund's shares is
determined by dividing the total market value of the securities owned by a Fund,
less its liabilities, by the total number of its outstanding shares. NAV is
determined at the close of regular trading on the New York Stock Exchange
(usually 4 p.m. Eastern Time) on each day the Exchange is open for trading.

The Funds do not calculate NAV on the following days:

  - Christmas Day
  - New Year's Day
  - Martin Luther King, Jr. Day
  - Presidents' Day
  - Good Friday
  - Memorial Day
  - Independence Day
  - Labor Day
  - Thanksgiving Day
  - Other days when the New York Stock Exchange is not open.

Each Fund reserves the right not to determine its NAV when:

  - It has not received any orders to purchase, sell or exchange shares
  - Changes in the value of the Fund's portfolio do not affect its NAV.

If current prices are not available, or if Villanova SA Capital Trust (VSA) as a
Fund's administrator or its agent determines a price does not represent fair
value, a Fund's investments may be valued at fair market value in accordance
with procedures adopted by the Board of Trustees. To the extent that a Fund's
investments are traded in markets that are open when the New York Stock Exchange
is closed, the value of the Fund's investments may change on days when shares
cannot be purchased or redeemed.

SELLING SHARES

You can sell -- also known as redeeming -- at any time, subject to certain
restrictions described below. The redemption price will be the NAV next
determined after the order is received. Of course, the value of the shares sold
may be more or less than their original purchase price depending upon the market
value of a Fund's investments at the time of sale.

DISTRIBUTIONS AND TAXES

RESTRICTIONS ON SALES

Shares of a Fund may not be redeemed or a Fund may delay paying you the proceeds
from a sale when the New York Stock Exchange is closed (other than customary
weekend and holiday closings) or if trading is restricted or if an emergency
exists.

DIVIDENDS AND DISTRIBUTIONS

Substantially all of a Fund's net investment income, if any, will be paid as a
dividend each quarter in the form of additional shares of the Fund. Any net
capital gains realized by a Fund from the sale of its portfolio securities will
be declared and paid to shareholders annually.

TAX STATUS

The tax treatment of payments made under a variable annuity contract or variable
life insurance policy is described in the prospectus for the contract or policy.
Generally, the owners of variable annuity contracts and variable life insurance
policies are not taxed currently on income or gains realized under such
contracts until the income or gain is distributed. However, income distributions
from these contracts and policies will be taxable at ordinary income tax rates.
In addition, distributions made to an owner who is younger than 59 1/2 may be
subject to a 10% penalty tax. Investors should ask their own tax advisers for
more information on their own tax situation, including possible state or local
taxes.

Please refer to the SAI for more information regarding the tax treatment of the
Funds.
