potential for sustained capital growth over the long term.
       The investment objective of the Government Bond Fund is to provide as
high a level of income as is consistent with the preservation of capital.
       The investment objective of the Money Market Fund is to seek as high a
level of current income as is considered consistent with the preservation of
capital and liquidity.

The information in the above tables has been audited by KPMG Peat Marwick LLP,
Independent Auditors, whose reports, thereon insofar as it relates to each of
the years in the five year period ended December 31, 1996, appears in the
Statement of Additional Information. The Statement of Additional Information and
the Annual Report for the Funds, which contains further information about the
Funds' performance may be obtained free of charge by calling 1-614-249-5134.
These Financial Highlights should be read in conjunction with the audited
financial statements for each Fund.

SALE OF FUND SHARES
    Currently, shares of the Funds are sold only to life insurance company
separate accounts (the "Accounts") to fund the benefits of variable insurance or
annuity policies ("Contracts") issued by life insurance companies. The Accounts
purchase shares of the Trust in accordance with variable account allocation
instructions received from owners of the Contracts. Each Fund then uses the
proceeds to buy securities for its portfolios. The investment adviser manages
the portfolios from day to day to accomplish a Fund's investment objectives. The
kinds of investments and the way they are managed depend on what is happening in
the economy and the financial marketplaces. Each of the Accounts, as a
shareholder, has an ownership in the Trust's investments. The Trust also offers
to buy back (redeem) shares of the Trust from the Accounts at any time at net
asset value.

INVESTMENT OBJECTIVES AND POLICIES

<PAGE>   12

    Investments in each Fund are made in many different securities which provide
diversification to minimize risk. While there is careful selection and constant
supervision by a team of professional investment managers, there can be no
guarantee that the Funds' objectives will be achieved. The fundamental policies
of each Fund do not require shareholder approval to change a Fund's investment
objective.

    -Total Return Fund
    The investment objective of this Fund is to obtain a reasonable, long term
total return (i.e. earnings growth plus potential dividend yield) on invested
capital from a flexible combination of current return and capital gains through
investments in common stocks, convertible issues, money market instruments, and
bonds, with a primary emphasis on common stocks.
    By investing in securities that are subject to market risk, the Fund is
subject to more fluctuations in its market value and involves the assumption of
a higher degree of risk as compared to a portfolio seeking stability of
principal, such as a money market portfolio or a portfolio investing in
corporate debt securities, United States and Canadian government obligations and
commercial paper.
    While it is the Fund's intention to invest in common stocks or in issues
convertible to common stock, there are no restrictive provisions covering the
proportion of one or another class of securities that may be held, other than
those stated in the Statement of Additional Information.
    Portfolio Manager: John M. Schaffner, MBA, CFA,is the portfolio manager for
the Total Return Fund. He has been with Nationwide since 1977 and has managed
the Total Return Fund since 1982. He also manages the Nationwide Growth Fund. He
graduated with a Bachelor of Arts in Economics from Occidental College. He
received his Masters of Business Administration degree from the University of
Michigan and is a Chartered Financial Analyst.

    -Capital Appreciation Fund
    The Fund is designed for investors who are interested in long-term growth.
The Fund seeks to meet its objectives primarily through a diversified portfolio
of the common stock of companies which the investment manager determines have a
better-than-average potential for sustained capital growth over the long term.
    While it is the Fund's intention to invest in common stocks or in issues
convertible to common stock, there are no restrictive provisions covering the
proportion of one or another class of securities that may be held, other than
those stated in the Statement of Additional Information.
    The investment manager will focus mainly on a company's or industry's
potential for long-term growth, with dividend and interest income being
secondary in importance. The manager's evaluation of a company or industry will
be based more on probable future earnings, relative financial strength and
competitive position. The manager believes this approach will provide a greater
return potential over the long run than simply seeking current dividend or
interest income. The Fund's portfolio will not be limited to any particular type
of company or industry.
    Portfolio Manager: Charles Bath, MBA, CFA, CPA,is the portfolio manager of
the Capital Appreciation Fund. Charles joined Nationwide as a securities analyst
and has managed the Capital Appreciation Fund since 1992. He has also managed
the Nationwide Fund since 1985. He graduated with a Bachelor of Science in
Accounting from Miami University. He received his Master of Business
Administration degree in Finance from The Ohio State University and is a
Certified Public Accountant and a Chartered Financial Analyst.

    -Government Bond Fund
    The investment objective of this Fund is to provide as high a level of
income as is consistent with the preservation of capital. It seeks to achieve
its objective by investing in a diversified portfolio of securities issued or
backed by the U.S. Government, its agencies or instrumentalities. These
securities are of varying maturities and types. They include direct obligations
of the U.S. Government backed by the full faith and credit of the United States,
such as U.S. Treasury bills, notes and bonds. Bills mature in one year or less,
notes in one to ten years, and bonds in ten years or more.
    In addition, the Fund will hold securities issued by U.S.
Government-chartered agencies and instrumentalities. These securities are
usually either guaranteed by the U.S. Treasury or are supported by the issuer's
rights to borrow from the Treasury and backed by the issuer's own credit.
Examples of such securities include but are not limited to, the 


<PAGE>   13

following:

            o the Federal Housing Administration, Farmers Home Administration,
              and the Government National Mortgage Association ("GNMA"),
              including GNMA pass-through certificates, whose securities are
              supported by the full faith and credit of the United States;

            o the Federal Home Loan Banks and the Tennessee Valley Authority,
              whose securities are supported by the right of the agency to
              borrow from the U. S. Treasury;

            o the Federal National Mortgage Association ("FNMA"), whose
              securities are supported by discretionary authority of the U. S.
              Government to purchase certain obligations of the agency or
              instrumentality; and

            o the Federal Home Loan Mortgage Corporation ("Freddie Mac") and the
              Student Loan Marketing Association, whose securities are supported
              only by the credit of such agencies.

       Although the U. S. Government provides financial support to such U. S.
Government-sponsored agencies or instrumentalities, no assurance can be given
that it will always do so. The U. S. Government and its agencies and
instrumentalities do not guarantee the market value of their securities;
consequently the value of such securities will fluctuate because the market
value of all debt obligations, including U. S. Government securities, is
affected by changes in the prevailing interest rates. The market value of such
obligations generally reacts inversely to interest rate changes. If the
prevailing interest rates decrease, the market value of debt obligations
generally increases. If the prevailing interest rates increase, the market value
of debt obligations generally decreases. In general, the longer the maturity of
a debt obligation, the greater its sensitivity to changes in interest rates.
    The Fund may invest in mortgage-related securities which represent part
ownership in a pool of mortgage loans. The Fund may acquire securities
representing an interest in a pool of mortgage loans that are issued or
guaranteed by GNMA, FNMA or Freddie Mac. Certain government agencies also issue
collateralized mortgage obligations ("CMOs") that are fully collateralized
directly or indirectly by a pool of mortgages on which payments or principal and
interest are dedicated to payment of principal and interest on the CMOs. These
securities differ from typical bonds because principal is repaid monthly over
the term of the loan rather than returned in a lump sum at maturity. In
addition, most mortgage-related securities are "pass-through" instruments,
through which the holder receives a share of all interest and principal payments
from the mortgages underlying the certificate. Because the prepayment
characteristics of the underlying mortgages vary, it is not possible to
accurately predict the average life or realized yield of a particular issue of
pass-through certificates. During periods of declining interest rates,
prepayment of mortgages underlying mortgage-related securities can be expected
to accelerate. When the mortgage obligations are prepaid, the Fund may have to
reinvest in securities with a lower yield. Moreover, prepayment of mortgages
which underlie securities purchased at a premium could result in capital losses.
       The Fund may also invest in zero-coupon securites that are direct
obligations of the U. S. Government and its agencies and instrumentalities.
Short-term securities of the Fund will include obligations with remaining
maturities of less than one year issued by the U. S. Goverment, its agencies and
instrumentalities and in repurchase agreements collateralized by securities in
which the Fund could otherwise invest.
       Portfolio Managers: Together, Wayne Frisbee, Kimberly Bingle, and Gary
Hunt are the portfolio managers for the Government Bond Fund. Mr. Frisbee joined
Nationwide in 1981 as a securities analyst and has managed the Government Bond
Fund since its inception in 1986. He received a Bachelor of Science from The
Ohio State University and is a Chartered Financial Analyst. He is also
co-manager of the Nationwide U.S. Government Income Fund. Ms. Bingle joined
Nationwide in 1986 as a securities analyst and began co-managing the Government
Bond Fund on May 1, 1997. Prior to May 1997, Ms. Bingle managed the fixed income
fund which is part of the Nationwide Insurance Enterprise incentive savings
plan. Ms. Bingle received a Bachelor of Arts in
Finance from the Pennsylvania State University. She is a Chartered Financial
Analyst and a Fellow of the Life Management Institute. She is also co-manager of
the Nationwide U.S. Government Income Fund. Mr. Hunt joined Nationwide in 1992
as a securities analyst. Mr. Hunt became co-manager of the Government Bond Fund
on May 1, 1997. In his career at Nationwide, Mr. Hunt has been responsible for
the analysis of agency CMOs 


<PAGE>   14

and U.S. treasury securities. In addition, Mr. Hunt has managed the commercial
mortgage-back securities sector for Nationwide Life Insurance Company and its
affiliates. Mr. Hunt received a Bachelor of Science in Finance and a Master of
Business Administration from The Ohio State University. He is also co-manager of
the Nationwide U.S. Government Income Fund.

    -Money Market Fund
    The investment objective of the Fund is to seek as high a level of current
income as is considered consistent with the preservation of capital and
liquidity by investing primarily in money market instruments, including U.S.
government securities, obligations of larger banks, prime commercial paper, high
grade, short term corporate obligations (with remaining maturities of 397 days
or less), U.S. dollar denominated obligations of foreign governments and
securities of foreign issuers and foreign branches of U.S. banks.
    Pursuant to its objectives of maintaining a fixed one dollar share price,
the Fund will not purchase securities with a remaining maturity of more that 397
days and will maintain a dollar weighted average portfolio maturity of 90 days
or less.
    Yields on such short-term instruments are very sensitive to short-term
lending conditions. The principal value of such instruments tends to decline as
interest rates rise and conversely tends to rise as interest rates decline. In
addition, there is an element of risk in such money market instruments that the
issuer may become insolvent and default in meeting interest and principal
payments.
    The Money Market Fund's yield and compound yield for the last seven days of
its most recent fiscal year ended December 31, 1996, was 4.95% and 5.07%
respectively. This yield quotation may be of limited use for comparative
purposes because it does not reflect charges imposed at the Account level which,
if included, would decrease the yield. For the current yield of the Fund, please
call (614) 249-5134.
    Portfolio Manager: Karen G. Mader, is the portfolio manager of the Money
Market Fund. Karen received a Bachelor of Arts degree in Political Science and a
Masters degree in International Business and Political Science, both from The
Ohio State University. She has managed the Money Market Fund since 1987.

MANAGEMENT DISCUSSION OF FUND PERFORMANCE

Total Return Fund


<PAGE>   15

    For the year ended 12/31/96, the Total Return Fund had a total return of
21.8%, compared to a return of 22.9% for the S&P 500 index. According to
Morningstar, the Fund's total return for the year ranked in the top half of its
peer group, ranking at #149 of 356 comparable Growth & Income variable annuity
products. These are respectable results considering that the Fund's investment
style, which is value-oriented and risk adverse, has been out of favor in the
stock market this year.
    While not heavily weighted with technology stocks, the Fund did benefit from
the names it held, Intel Corp. (before it was sold) and IBM both of which
provided strong year-over-year gains. The financial sector, where the Fund has
good representation, had another strong year; the brokerage and bank stocks held
by the Fund all did well and Allstate Corp., among the insurance stocks, had the
best performance. Energy, another sector where the Fund has a significant asset
weighting and which was increased to during the year, also showed impressive
gains for the year. Individual stocks that had strong performance included
Warner-Lambert Co. and Monsanto Co. Dragging down results was the performance of
the telecommunications sector, with the exception of MCI Communications Corp.,
which had respectable gains as a result of the proposed merger. Individual
stocks, such as (The) Olsten Corp. and Comcast Corp., which we continue to like
long-term, lagged the overall market considerably this year and also hindered
results.
    Cash and equivalents has been reduced from last year's levels, from about
13% at year-end 1995 to about 7% at year-end 1996. The Fund has found more
opportunities to buy securities with favorable fundamentals on a long-term basis
when these securities disappoint short-term investors. The purchases of (The)
Olsten Corp., Electronic Data Systems, and 360(0) Communications Company are
examples of this strategy.

Capital Appreciation Fund
      The total return for the Capital Appreciation Fund for the year ended
December 31, 1996 was 26.1% compared to 22.9% for the S&P 500. The performance
was helped considerably by a large holding in IBM. IBM returned 67% for the
year. The best performing stock was Morningstar Group. This small speciality
dairy company returned 145% for 1996. This unusually larger gain contributed to
the outperformance of the Capital Appreciation Fund for the fourth quarter and
the year.
      The largest holding in the Capital Appreciation Fund is Warner-Lambert
Company. The company recently received approvals from the Food and Drug
Administration for two important new drugs. These new products serve the
cardiovascular and diabetes markets and should successfully accelerate the
earnings growth rate for several years to come. Warner-Lambert returned in
excess of 57% in 1996.
      There were several corporate events in the fourth quarter involving the
Capital Appreciation Fund's holdings. In particular, Dun & Bradstreet Corp. and
Corning, Inc. each split into three separately traded public corporations.
Historically, these actions are positive for shareholders as diverse companies
narrow their focus on their core competencies. We continue to hold Corning and
Dun & Bradstreet and have bought additional shares of the spun-off companies.
The performance of the Capital Appreciation Fund for 1997 will partially depend
on the success of these restructured companies.

                       predictive of future performance.



Government Bond Fund
    The total return for the Government Bond Fund for 1996 was 3.5%. The Merrill
Lynch Government Master Index, an index designed to reflect the performance of
the broad Government and Agency market, returned 2.76% during the same period.
      The year ended December 31, 1996 was a difficult one for bond investors.
It was difficult on an absolute basis as interest rates rose and limited bond
market returns to the low single digits. But, it was also difficult on an
absolute basis as these same investors enviously watched a second consecutive
year of outstandinding returns in the stock markets. It is at times such as
these that investors must remind themselves that investing requires a long-term
time horizon and that an appropriate mix is the most important element of
successful investing.
      The Government Bond Fund was successful during 1996 investing in various
callable agency structures. These are bonds that are redeemable prior to
maturity at the option of the issuer. The Fund, as investor, is compensated for
the risk of early redemption with a higher market yield. This strategy was
successful because the 



<PAGE>   19

bond market traded in a relatively narrow range during much of the year, thus
rewarding those investors who were in higher yielding instruments. The theme of
investing for incremental yield can also be seen in the holdings of
Collateralized Mortgage Obligations (CMO's) where approximately one-third of
portfolio assets are invested. The additional yield on these
conservatively-structured investments continues to make them attractive
portfolio holdings.
    Incremental yield of course does not allow the Fund to avoid the effects of
higher interest rates. Fund share prices moved lower reflecting the impact of
rates that were approximately 75 basis points higher during the year. The
Government Bond Fund continues to be invested in sectors of the government,
agency, and mortgage-backed markets perceived to be undervalued, attempting to
add value relative to the market averages while maintaining exposure to the
broad Government market.

Money Market Fund

<PAGE>   20

      March 1997 marked the beginning of the seventh year of expansion for the
U.S. economy. Economic indicators continue to suggest that the economy is
expanding. On March 25, 1997, the Federal Reserve made its move and raised short
- -term interest rates. This move, which is the first since January 1996, raised
the target for the Fed Funds rate to 5.50% from 5.25%. Future increases may be
necessary as some economists argue that a 25 basis point increase will do little
to contain inflationary pressures.
     At December 31, 1996, the Money Market Fund had assets of $984 million with
an average maturity of 38 days. 92% of the Fund was invested in first tier
commercial paper with the remaining 8% invested in U.S. Government and Agency
securities and Canadian Government Obligations.
    The Fund continues to invest in only first tier money market instruments. An
internal credit review is completed on every issuer prior to investment.

INVESTMENT IN FUND SHARES
    An insurance company purchases the shares of the Funds at their net asset
value using purchase payments received on Contracts issued by Accounts. These
Accounts are funded by shares of the Trust. There is no sales charge. All shares
are sold at net asset value.
    Shares of the Trust are currently sold only to separate accounts of
Nationwide Life Insurance Company and Nationwide Life and Annuity Insurance
Company, One Nationwide Plaza, Columbus, Ohio 43216, to fund the benefits under
variable insurance or annuity policies.
    All investments in the Trust are credited to the shareholder's account in
the form of full and fractional shares of the designated Fund (rounded to the
nearest 1/1000 of a share). The Trust does not issue share certificates. Initial
and subsequent purchase payments allocated to a specific Fund are subject to the
limits applicable to the policies.

SHARE REDEMPTION
    An Account redeems shares to make benefit or surrender payments under the
terms of its Contracts. Redemptions are processed on any day on which the Trust
is open for business and are effected at net asset value next determined after
the redemption order, in proper form, is received by the Trust's transfer agent,
NIS.
    The net asset value per share of each Fund is determined once daily, as of
4:00 P.M. on each business day the New York Stock Exchange is open and on such
other days as the Board determines and on any other day during which there is a
sufficient degree of trading in a Fund's portfolio securities that the net asset
value of the Fund is materially affected by changes in the value of portfolio
securities. The Trust will not compute net asset value on customary national
business holidays, including the following: Christmas, New Year's Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, and
Thanksgiving. The net asset value per share is calculated by adding the value of
all securities and other assets of a Fund, deducting its liabilities, and
dividing by the number of shares outstanding.
    In determining net asset value, portfolio securities listed on national
exchanges or actively traded in the over-the-counter market are valued at the
last quoted sale price; if there is no sale on that day, the securities are
valued at the prior day's closing price for exchange-traded securities or at the
quoted bid price for over-the-counter-traded securities. Other portfolio
securities, except securities in the Money Market Fund, are valued at the quoted
prices obtained from an independent pricing organization which employs a
combination of methods, including among others, the obtaining and comparison of
market valuations from dealers who make markets and deal in such securities and
the comparison of valuations with those other comparable securities in a matrix
of such securities. The pricing service activities and results are reviewed by
an officer of the Trust. Securities for which market quotations are not readily
available are valued at fair value in accordance with procedures adopted by the
Board of Trustees. Portfolio securities in the Money Market Fund are valued at
amortized cost in compliance with procedures adopted under Rule 2a-7. Expenses
and fees are accrued daily.

       The Trust may suspend the right of redemption only under the following
unusual circumstances:
            o when the New York Stock Exchange is closed (other than weekends
              and holidays) or trading is restricted;
            o when an emergency exists, making disposal of portfolio securities
              or the valuation of net assets not reasonably practicable; or
            o during any period when the Securities and Exchange Commission has
              by order permitted a suspension of redemption for the protection
              of shareholders.


NET INCOME AND DISTRIBUTIONS

<PAGE>   22

    -Total Return Fund, Capital Appreciation Fund and Government Bond Fund
    Substantially all of the net investment income, if any, of these Funds will
be declared as dividends in March, June, September, and December. In those years
in which sales of a Fund's portfolio securities result in net realized capital
gains, the Fund will distribute such gains to its shareholders in January
following a December declaration.
    -Money Market Fund
    The net income of the Money Market Fund is determined once daily, as of the
close of the New York Stock Exchange (currently 4:00 P.M., New York time) on
each business day the Exchange is open. All the net income of the Fund, so
determined, is declared in shares as a dividend to shareholders of record at the
time of such determination. (Shares purchased become entitled to dividends
declared as of the first day following the date of investment.) Dividends are
distributed in the form of additional shares of the Fund on the last business
day of each month at the rate of one share (and fraction thereof) of the Fund
for each one dollar (and fraction thereof) of dividend income.
    For this purpose, the net income of the Money Market Fund (from the time of
the immediately preceding determination thereof) shall consist of: (a) all
interest income accrued on the portfolio assets of the Fund, (b) less all actual
and accrued expenses, and (c) plus or minus net realized gains and losses on the
assets of the Fund determined in accordance with generally accepted accounting
principles. Interest income shall include discount earned (including both
original issue and market discount) on discount paper accrued ratably to the
date of maturity. Securities are valued at market or amortized cost which
approximates market, for purposes of complying with the Investment Company Act
of 1940.
    Net income of the Fund is declared as a dividend each time the net income is
determined. This is one reason the net asset value per share (i.e., the value of
the net assets of the Fund divided by the number of shares outstanding) remains
at one dollar per share immediately after each such determination and dividend
declaration.

ADDITIONAL INFORMATION
    Description of Shares--The Declaration of Trust permits the Trustees to
issue an unlimited number of full and fractional shares of beneficial interest
of each Fund and to divide or combine such shares into a greater or lesser
number of shares without thereby changing the proportionate beneficial interests
in the Trust. Each share of a Fund represents an equal proportionate interest in
that Fund with each other share. The Trust reserves the right to create and
issue shares for a number of different Funds. In that case, the shares of each
Fund would participate equally in the earnings, dividends, and assets of the
particular Fund, but shares of all Funds would vote together in the election of
Trustees. Upon liquidation of a Fund, its shareholders are entitled to share pro
rata in the net assets of such Fund available for distribution to shareholders.
    Voting Rights--Shareholders are entitled to one vote for each share held.
Shareholders may vote in the election or removal of Trustees and on other
matters submitted to meetings of shareholders. Although the sole shareholders of
the Trust are Nationwide Life insurance Company and Nationwide Life and Annuity
Insurance Company, under current law, the life insurance company shareholders
are required to request voting instructions from policyholders and must vote
Trust shares held in proportion to the voting instructions received. No
amendment may be made to the Declaration of Trust without the affirmative vote
of a majority of the outstanding shares of the Trust. The Trustees may, however,
amend the Declaration of Trust without the vote or consent of shareholders to:
            o designate series of the Trust;
            o change the name of the Trust; or
            o supply any omission, cure, correct, or supplement any ambiguous,
              defective, or inconsistent provi- sion to conform the Declaration
              of Trust to the requirements of applicable federal and state laws
              or regulations if they deem it necessary.

Shares have no pre-emptive or conversion rights. Shares are fully paid and
nonassessable, except as set forth below. In regard to termination, sale of
assets, or changes of investment restrictions, the right to vote is limited to
the holders of shares of the particular Fund affected by the proposal. When a
majority is required, it means the lesser of 67% or more of the shares present
at a meeting when the holders of more than 50% of the outstanding shares are
present or represented by proxy, or more than 50% of the outstanding shares.

PERFORMANCE ADVERTISING FOR THE FUNDS
    The Funds may use historical performance in advertisements, sales
literature, and the prospectus. Such figures will include quotations of average
total return for the most recent one, five, and ten year periods (or the life of
the Fund if less). Average annual total return represents the rate required each
year for an initial investment to equal the redeemable value at the end of the
specific period. Average annual total return reflects reinvestment of all
distributions.
    The Government Bond Fund may advertise yield which is calculated daily
dividing the net investment income per share earned during a 30-day period by
the maximum offering price per share on the last day of the period.
    The Money Market Fund may advertise current seven-day yield quotations
computed by determining the net change, exclusive of capital changes, in the
value of a hypothetical pre-existing account having a balance of one share at
the beginning of the base period to obtain a base period return and then
multiplying the base period return by (365/7), or (366/7) in a leap year. For
purposes of this calculation, the net change in account value reflects the value
of additional shares purchased with dividends from the original share, and
dividends declared on both the original share and any such additional shares.
The Fund's effective yield represents a compounding on an annualized basis of
the current yield quotation of the Fund.
    Shareholder Inquiries--All inquiries regarding the Trust should be directed
to the Trust at the telephone number or address shown on the cover page of this
Prospectus.

TAX STATUS
    The Trust's policy is for each Fund to qualify as a regulated investment
company and to meet the requirements of Subchapter M of the Internal Revenue
Code. Each Fund intends to distribute all its taxable net investment income and
capital gains to shareholders, and therefore, will not be required to pay any
federal income taxes.
    Because each Fund of the Trust is treated as a separate entity for purposes
of the regulated investment company provisions of the Code, the assets, income
and distributions of a Fund are considered separately for purposes of
determining whether or not a Fund qualifies as a regulated investment company.
Each Fund intends to comply with the diversification requirements currently
imposed by the Internal Revenue Service on separate accounts of insurance
companies as a condition of maintaining the tax-deferred status of the
Contracts. See the Statement of Additional Information for more specific
information.

    The tax treatment of payments made by a separate account to a Contract
holder is described in the separate account prospectus.

                         NATIONWIDE SMALL COMPANY FUND

At a Special Meeting of Shareholders held on September 26, 1997, Shareholders 
of the Nationwide Small Company Fund (the "Fund") approved a proposal which 
authorizes the Board of Trustees to appoint, replace or terminate subadvisers 
without the approval of the Fund's shareholders; the order would also allow 
Nationwide Advisory Services, Inc. ("NAS") to revise a subadvisory agreement 
without shareholder approval. This authorization will only be utilized if an 
exemptive order which NAS and Nationwide Separate Account Trust (the "Trust"), 
on behalf of the Fund, have applied for is granted by the Securities and 
Exchange Commission. If the order is granted, any change in subadvisers will be 
communicated to shareholders within 60 days of such changes and all changes 
will be approved by the Trust's Board of Trustees, including a majority of the 
Trustees who are not interested persons of the Trust or NAS. The order, if 
granted, is intended to facilitate the efficient operation of the Fund and 
afford the Trust increased management flexibility. Prior to receiving the 
exemptive order, NAS will not appoint, replace or terminate any subadvisers or 
materially amend any subadvisory agreement without obtaining the approval of
shareholders.

SALE OF FUND SHARES

           Currently, shares of the Fund are sold only to life insurance company
separate accounts ("Accounts") to fund the benefits of variable insurance or
annuity policies ("Contracts") issued by life insurance companies. The Accounts
purchase shares of the Fund in accordance with variable account allocation
instructions received from owners of the Contracts. The Fund then uses the
proceeds to buy securities for its portfolio. The investment adviser, together
with a group of subadvisers, manages the portfolio from day to day to accomplish
the Fund's investment objective. The types of investments and the way they are
managed depend on what is happening in the economy and the financial
marketplaces. Each of the Accounts, as a shareholder, has an ownership in the
Fund's investments. The Fund also offers to buy back (redeem) shares of the Fund
from the Accounts at any time at net asset value.

INVESTMENT OBJECTIVE AND POLICIES

           Nationwide Small Company Fund (the "Fund") seeks long-term growth of
capital. The Fund invests primarily in equity securities of small market
capitalization companies ("small company stocks"). Market capitalization means
the total market value of a company's outstanding common stock. The Fund
anticipates that under normal market conditions, the Fund will invest at least
65% of its assets in equity securities of domestic and foreign companies with
market capitalizations of less than $1 billion at the time of purchase. The
equity securities in which the Fund may invest include common stocks, preferred
stocks (both convertible and non-convertible), warrants and rights. It is
anticipated that the Fund will invest primarily in companies whose securities
are traded on foreign or domestic stock exchanges or in the over-the-counter
market ("OTC"). The Fund may also invest in securities of emerging growth
companies, some of which may have market capitalizations over $1 billion.
Emerging growth companies are companies which have passed their start-up phase
and which show positive earnings and prospects of achieving significant profit
and gain in a relatively short period of time.

           The Fund may purchase an unlimited number of foreign securities,
including securities of companies in emerging markets. The Fund may also invest
in foreign securities indirectly through American Depository Receipts ("ADRs")
and other similar instruments as described below in "INVESTMENT TECHNIQUES,
CONSIDERATIONS AND RISK FACTORS - Foreign Securities and Currencies".

           Under normal conditions, the Fund intends to invest primarily in
small company stocks; however, the Fund is also permitted to invest up to 35% of
its assets in equity securities of domestic and foreign issuers with a market
capitalization of more than $1 billion at the time of purchase, debt obligations
and domestic and foreign money market instruments, including bankers
acceptances, certificates of deposit and discount notes of U.S. Government
securities. In addition, for temporary or emergency purposes, the Fund can
invest up to 100% of total assets in cash, cash equivalents, U.S. Government
securities, commercial paper and certain other money market instruments, as well
as repurchase agreements collateralized by these types of securities.

           At various times the Fund may invest in derivative instruments for
hedging or risk management purposes or for any other permissable purpose. See
"INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS - Derivative
Instruments" below.

           While there is careful selection and constant supervision by a group
of professional investment managers, there can be no guarantee that the Fund's
objective will be achieved. The fundamental policies of the Fund do not require
shareholder approval to change the Fund's investment objective.

MANAGEMENT OF THE FUND

           Nationwide Advisory Services, Inc. ("NAS" or "Adviser") has employed
a group of subadvisers (each, a "Subadviser"), each of which will manage part of
the Fund's portfolio. Although the Adviser reserves the right to allocate and
reallocate the assets among the Subadvisers at any time, it is anticipated that
each of the Subadvisers will receive a substantially equal proportion of the
funds that are invested in the Fund and will generally retain such assets and
any capital appreciation attributable to them. In addition, it is anticipated
that the Adviser will maintain a portion of the Fund's assets in cash or money
market instruments.

           The Adviser has chosen the Subadvisers because they utilize a number
of different investment styles when investing in small company stocks. The
Adviser has decided to employ a number of Subadvisers because even successful
investment managers may experience fluctuations in performance which may be
caused by factors or conditions that affect the particular securities emphasized
by that Subadviser or that may impact its particular investment style. As a
result of the diversification among securities and styles, the Adviser hopes to
increase prospects for investment return and to reduce market risk and
volatility.


<PAGE>   31


           The following is a brief description of the investment strategies for
each of the Subadvisers:

           The Dreyfus Corporation ("Dreyfus") primarily seeks out domestic and
foreign small company stocks that have the potential for significant growth.
Dreyfus believes these companies to be characterized by new or innovative
products or services which should enhance prospects for growth in future
earnings. Dreyfus will also make investments based on prospective economic or
political changes and will invest in securities relating to special situations,
such as corporate restructurings, mergers or acquisitions, thereby seeking out
undervalued securities.

           Neuberger & Berman, L.P. ("Neuberger & Berman") tries to enhance the
potential for appreciation and limit the risk of decline in the value of the
small company stocks that it purchases for the Fund by employing a
value-oriented investment approach. Neuberger & Berman seeks securities that
appear to be underpriced and are issued by companies with proven management,
sound finances and strong potential for market growth. It focuses on the
fundamentals of each smaller company, instead of trying to anticipate what
changes might occur in the stock market or in the economy or the political
environment; in doing so, the Fund's securities will be selected in the belief
that they are currently undervalued, based on existing conditions.

           Strong Capital Management, Inc. ("Strong") invests in companies whose
earnings are believed to be in a relatively strong growth trend, and, to a
lesser extent, in companies in which significant further growth is not
anticipated but which are perceived to be undervalued. In identifying companies
with favorable growth prospects, Strong considers factors such as prospects for
above-average sales and earnings growth; high return on invested capital;
overall financial strength; competitive advantages, including innovative
products and services; effective research, product development and marketing;
and stable, capable management.

           Pictet International Management Limited ("PIML") and Van Eck
Associates ("VEAC") together invest internationally in small company stocks.
PIML and VEAC will primarily choose securities of issuers whose individual
market capitalizations would place them at the time of purchase in the same size
range as companies in approximately the lowest 20% by total market
capitalization of companies that have equities listed on major U.S. exchanges or
traded in the NASDAQ system. These companies will typically have individual
market capitalizations below $500 million. Because this policy is applied on an
international basis, the Fund may invest in companies that may rank above the
lowest 20% by total market capitalization in local markets and in some countries
such companies might rank among the largest companies in terms of
capitalization. When considering where assets will be allocated abroad, VEAC and
PIML will assess where opportunities for long-term capital appreciation are
greatest. In making specific stock selections, VEAC and PIML will invest in
quality, growth-oriented smaller companies that are relatively inexpensive.

           Warburg, Pincus Counsellors, Inc. ("Warburg") invests primarily in
domestic small company stocks. Warburg may choose securities of small companies
which may be in the developmental stage, may be older companies that appear to
be entering a new stage of growth owing to factors such as management changes or
development of new technology, products or markets or may be companies providing
products or services with a high unit volume growth rate. Warburg may also
select securities of emerging growth companies, which can be either small- or
medium-sized companies that have passed their start-up phase and that show
positive earnings and prospects of achieving significant profit and gain in a
relatively short period of time. Emerging growth companies generally stand to
benefit from new products or services, technological developments or changes in
management and other factors and include smaller companies experiencing unusual
developments affecting their market value.

MANAGEMENT DISCUSSION OF FUND PERFORMANCE

           The total return for the Small Company Fund for 1996 was 22.8%,
compared to 16.5% for the Russell 2000 Index. The Fund excelled during the year
in large part due to overweighting in the energy and financial sectors. The
Energy sub-index of the Russell 2000 advanced 74.8% during the year. The Small
Company Fund shared in those gains with investments in Pride Petroleum Services,
Inc., an oil field service firm, and Flores & Rucks, Inc., an exploration and
production company. Numerous investments in the Financial Services sub-index
rose 27.6% for the year.
           The Fund's international holdings provided less of a boost, rising by
5.3% during the year. Small capitalization stocks trailed their larger
capitalization counterparts internationally, as in the U.S. The Small Company
Fund benefited from the strong performance of its investments in Scandinavian
countries, while housing and retail sectors investments in other areas of Europe
were disappointing.
           The Fund maintains a high degree of diversification in its holdings.
As of December 31, 1996, the Small Company Fund held over 650 stocks, with the
largest holding accounting for less than 1% of total assets.
           Though small capitalization stocks have trailed large capitalization
securities recently, the Subadvisors continue to identify and invest in small
companies whose stocks they believe offer attractive appreciation potential.

INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS

Small Company and Emerging Growth Stocks

           Investing in securities of small-sized and emerging growth companies
may involve greater risks than investing in larger, more established issuers
since these securities may have limited marketability and, thus, they may be
more volatile than securities of larger, more established companies or the
market averages in general. Because small-sized companies normally have fewer
shares outstanding than larger companies, it may be more difficult for the Fund
to buy or sell significant numbers of such shares without an unfavorable impact
on prevailing prices. Small-sized companies may have limited product lines,
markets or financial resources and may lack management depth. In addition,
small-sized companies are typically subject to wider variations in earnings and
business prospects than are larger, more established companies. There is
typically less publicly available information concerning small-sized companies
than for larger, more established ones.

           Securities of issuers in "special situations" also may be more
volatile, since the market value of these securities may decline in value if the
anticipated benefits do not materialize. Companies in "special situations"
include, but are not limited to, companies involved in an acquisition or
consolidation; reorganization; recapitalization; merger, liquidation or
distribution of cash, securities or other assets; a tender or exchange offer, a
breakup or workout of a holding company; litigation which, if resolved
favorably, would improve the value of the companies' securities; or a change in
corporate control.

           Although investing in securities of emerging growth companies or
"special situations" offers potential for above-average returns if the companies
are successful, the risk exists that the companies will not succeed and the
prices of the companies' shares could significantly decline in value. Therefore,
an investment in the Fund may involve a greater degree of risk than an
investment in other mutual funds that seek long-term growth of capital by
investing in better-known, larger companies.

Foreign Securities and Currencies

           The Fund may invest in foreign securities, either directly or
indirectly through the use of depositary receipts. Depositary receipts,
including ADRs, European Depository Receipts and American Depository Shares, are
generally issued by banks or trust companies and evidence ownership of
underlying foreign securities. The Fund may also invest in securities of foreign
investment funds or trusts (including passive foreign investment companies).


<PAGE>   33


           Foreign investments involve special risks, including the possibility
of expropriation, confiscatory taxation, and withholding taxes on dividends and
interest; less extensive regulation of foreign brokers, securities markets, and
issuers; political, economic or social instability; and less publicly available
information and different accounting standards. When investing in foreign
securities, the Fund may also incur costs in conversions between currencies,
possible delays in settlement in foreign securities markets, limitations on the
use or transfer of assets (including suspension of the ability to transfer
currency from a given country), and difficulty in enforcing obligations in other
countries.

           Foreign economies may differ favorably or unfavorably from the U.S.
economy in various respects, including growth of gross domestic product, rates
of inflation, currency depreciation, capital reinvestment, resource
self-sufficiency, and balance of payments positions. Many foreign securities are
less liquid and their prices more volatile than comparable U.S. securities.
Although the Fund generally invests only in securities that are regularly traded
on recognized exchanges or OTC, from time to time, foreign securities may be
difficult to liquidate rapidly without adverse price effects. Certain costs
attributable to foreign investing, such as custody charges and brokerage costs,
are higher than those attributable to domestic investing.

           The Fund may invest a portion of its assets in securities of issuers
in developing or emerging markets and economies. Investing in securities of
issuers in developing or emerging markets involves special risks, including less
social, political, and economic stability; smaller securities markets and lower
trading volume, which may result in a lack of liquidity and greater price
volatility; certain national policies that may restrict the Fund's investment
opportunities, including restrictions on investments in issuers or industries
deemed sensitive to national interests, or expropriation or confiscation of
assets or property, which could result in a Fund's loss of its entire investment
in that market; and less developed legal structures governing private or foreign
investment or allowing for judicial redress for injury to private property.

           In addition, brokerage commissions, custodial services, withholding
taxes, and other costs relating to investment in emerging markets generally are
more expensive than in the U.S. and certain more established foreign markets.
Economies in emerging markets generally are heavily dependent upon international
trade and, accordingly, have been and may continue to be affected adversely by
trade barriers, exchange controls, managed adjustments in relative currency
values, and other protectionist measures negotiated or imposed by the countries
with which they trade.

           Because most foreign securities are denominated in non-U.S.
currencies, the investment performance of the Fund could be significantly
affected by changes in foreign currency exchange rates. The value of the Fund's
assets denominated in foreign currencies will increase or decrease in response
to fluctuations in the value of those foreign currencies relative to the U.S.
dollar. Currency exchange rates can be volatile at times in response to supply
and demand in the currency exchange markets, international balances of payments,
governmental intervention, speculation, and other political and economic
conditions.

           The Fund may purchase and sell foreign currency on a spot basis and
may engage in forward currency contracts, currency options, and futures
transactions for hedging or risk management purposes. (See "Derivative
Instruments" below.)

Warrants

           A warrant is an instrument which gives the holder the right to
subscribe to a specified amount of the issuer's securities at a set price for a
specified period of time or on a specified date.

Convertible Securities

           A convertible security is a fixed income security or preferred stock
that may be converted at either a stated price or stated rate into underlying
shares of common stock. Convertible securities have general characteristics
similar to both debt obligations and equity securities. Although to a lesser
extent than with debt obligations generally, the market value of convertible
securities tends to decline as interest rates increase and, conversely, tends to
increase as interest rates decline. In addition, because of the conversion
feature, the market value of convertible securities tends to vary with
fluctuations in the market value of the underlying common stock, and therefore,
also will react to variations in the general market for equity securities. A
unique feature of convertible securities is that as the market price of the
underlying common stock declines, convertible securities tend to trade
increasingly on a yield basis, and so may not experience market value declines
to the same extent as the underlying common stock. When the market price of the
underlying common stock increases, the prices of the convertible securities tend
to rise as a reflection of the value of the underlying common stock. While no
securities investments are without risk, investments in convertible securities
generally entail less risk than investments in common stock of the same issuer.

<PAGE>   34

           As debt obligations, convertible securities are investments that
provide for a stable stream of income with generally higher yields than common
stocks. Of course, like all debt obligations, there can be no assurance of
current income because the issuers of the convertible securities may default on
their obligations. Convertible securities, however, generally offer lower
interest or dividend yields than non-convertible securities of similar quality
because of the potential for capital appreciation. A convertible security, in
addition to providing fixed income, offers the potential for capital
appreciation through the conversion feature, which enables the holder to benefit
from increases in the market price of the underlying common stock. There can be
no assurance of capital appreciation, however, because the market value of
securities will fluctuate.

           Convertible securities generally are subordinated to other similar
but non-convertible securities of the same issuer, although convertible bonds,
as corporate debt obligations, enjoy seniority in right of payment to all equity
securities, and convertible preferred stock is senior to common stock of the
same issuer. Because of the subordination feature, however, convertible
securities typically have lower ratings than similar non-convertible securities.

Debt Obligations

           In General - Debt obligations in which the Fund may invest will be
investment-grade debt obligations, although the Fund may invest up to 5% of its
assets in non-investment-grade debt obligations. The market value of all debt
obligations is affected by changes in the prevailing interest rates. The market
value of such instruments generally reacts inversely to interest rate changes.
If the prevailing interest rates decrease, the market value of debt obligations
generally increases. If the prevailing interest rates increase, the market value
of debt obligations generally decreases. In general, the longer the maturity of
a debt obligation, the greater its sensitivity to changes in interest rates.

           Investment-grade debt obligations include 1) bonds or bank
obligations rated in one of the four highest rating categories by any nationally
recognized statistical rating organization ("NRSRO") (e.g., Moody's Investors
Service, Inc. or Standard & Poor's Ratings Group ("Standard & Poor's")); 2) U.S.
government securities (as described below); 3) commercial paper rated in one of
the three highest ratings categories of any NRSRO; 4) short-term bank
obligations that are rated in one of the three highest categories by any NRSRO,
with respect to obligations maturing in one year or less; 5) repurchase
agreements involving investment-grade debt obligations; or 6) unrated debt
obligations which are determined by the Adviser or a Subadviser to be of
comparable quality.

           All ratings are determined at the time of investment. Any subsequent
rating downgrade of a debt obligation will be monitored by the Adviser or a
Subadviser to consider what action, if any, the Fund should take consistent with
its investment objective; such event will not automatically require the sale of
the downgraded securities. Securities rated in the fourth highest category by an
NRSRO, although considered investment-grade, have speculative characteristics
and may be subject to greater fluctuations in value than higher-rated
securities. Non-investment-grade debt obligations include 1) securities rated as
low as C by Standard & Poor's or its equivalents; 2) commercial paper rated as
low as C by Standard & Poor's or its equivalents; or 3) unrated debt securities
judged to be of comparable quality by the Adviser or a Subadviser.

           Repurchase Agreements - The Fund may engage in repurchase agreement
transactions as long as the underlying securities are of the type that the Fund
would be permitted to purchase directly. Under the terms of a typical repurchase
agreement, the Fund would acquire an underlying debt obligation for a relatively
short period (usually not more than one week) subject to an obligation of the
seller to repurchase, and the Fund to resell, the obligation at an agreed upon
price and time, thereby determining the yield during the Fund's holding period.
The Fund will enter into repurchase agreements with respect to securities in
which it may invest with member banks of the Federal Reserve System or certain
non-bank dealers. Under each repurchase agreement the selling institution will
be required to maintain the value of the securities subject to the repurchase
agreement at not less than their repurchase price. Repurchase agreements could
involve certain risks in the event of default or insolvency of the other party,
including possible delays or restrictions upon a Fund's ability to dispose of
the underlying securities. The Adviser or a Subadviser, acting under the
supervision of the Board of Trustees, reviews the creditworthiness of those
banks and non-bank dealers with which the Fund enters into repurchase agreements
to evaluate these risks. See "Repurchase Agreements" in the Statement of
Additional Information.

           U.S. Government Securities - U.S. government securities are issued or
guaranteed by the U.S. government or its agencies or instrumentalities.
Securities issued by the government include U.S. Treasury obligations, such as
Treasury bills, notes, and bonds. Securities issued by government agencies or
instrumentalities include, but are not limited to, obligations of the following:

- -          the Federal Housing Administration, Farmers Home Administration, and
           the Government National Mortgage Association ("GNMA"), including GNMA
           pass-through certificates, whose securities are supported by the full
           faith and credit of the United States;

<PAGE>   35

- -          the Federal Home Loan Banks and the Tennessee Valley Authority, whose
           securities are supported by the right of the agency to borrow from
           the U.S. Treasury;

- -          the Federal National Mortgage Association, whose securities are
           supported by the discretionary authority of the U.S. government to
           purchase certain obligations of the agency or instrumentality; and

- -          the Student Loan Marketing Association and the International Bank for
           Reconstruction and Development, whose securities are supported only
           by the credit of such agencies.

           Although the U.S. government provides financial support to such U.S.
government-sponsored agencies or instrumentalities, no assurance can be given
that it will always do so. The U.S. government and its agencies and
instrumentalities do not guarantee the market value of their securities;
consequently, the value of such securities will fluctuate.

Derivative Instruments

           Derivative instruments may be used by the Fund for hedging or risk
management purposes or for any other permissible purposes consistent with the
Fund's investment objective. Derivative instruments are securities or agreements
whose value is based on the value of some underlying asset, for example,
securities, currencies, or reference indices. Options, futures, and options on
futures transactions are considered derivative transactions. Derivatives
generally have investment characteristics that are based upon either forward
contracts (under which one party is obligated to buy and the other party is
obligated to sell an underlying asset at a specific price on a specified date)
or option contracts (under which the holder of the option has the right but not
the obligation to buy or sell an underlying asset at a specified price on or
before a specified date). Consequently, the change in value of a forward-based
derivative generally is roughly proportional to the change in value of the
underlying asset. In contrast, the buyer of an option-based derivative generally
will benefit from favorable movements in the price of the underlying asset but
is not exposed to corresponding losses due to adverse movements in the value of
the underlying asset. The seller of an option-based derivative generally will
receive fees or premiums but generally is exposed to losses due to changes in
the value of the underlying asset. Derivative transactions may include elements
of leverage and, accordingly, the fluctuation of the value of the derivative
transaction in relation to the underlying asset may be magnified. In addition to
options, futures, and options on futures transactions, derivative transactions
may include short sales against the box, in which the Fund sells a security it
owns for delivery at a future date. Derivative transactions may also include
forward currency contracts and foreign currency exchange-related securities.

           Derivative transactions in which the Fund may engage include the
writing of covered put and call options on securities and the purchase of put
and call options thereon, the purchase of put and call options on securities
indexes and exchange-traded options on currencies and the writing of put and
call options on securities indexes. The Fund may enter into spread transactions
and swap agreements. The Fund also may buy and sell financial futures contracts
which may include interest-rate futures, futures on currency exchanges and stock
and bond index futures contracts. The Fund may enter into any futures contracts
and related options without limit for "bona fide hedging" purposes (as defined
in Commodity Futures Trading Commission regulations) and for other permissible
purposes, provided that aggregate initial margin and premiums on positions
engaged in for purposes other than "bona fide hedging" will not exceed 5% of its
net asset value, after taking into account unrealized profits and losses on such
contracts. The Fund may also enter into forward currency contracts to purchase
or sell foreign currencies.

           Derivative instruments may be exchange-traded or traded in OTC
transactions between private parties. OTC transactions are subject to the credit
risk of the counterparty to the instrument and are less liquid than
exchange-traded derivatives since they often can only be closed out with the
other party to the transaction. When required by guidelines of the Securities
and Exchange Commission ("SEC"), the Fund will set aside permissible liquid
assets or securities positions that substantially correlate to the market
movements of the derivatives transactions in a segregated account to secure its
obligations under derivative transactions. Segregated assets cannot be sold or
transferred unless equivalent assets are substituted in their place or it is no
longer necessary to segregate them. As a result, there is a possibility that
segregation of a large percentage of the Fund's assets could impede portfolio
management or the Fund's ability to meet redemption requests or other current
obligations. In order to maintain its required cover for a derivative
transaction, the Fund may need to sell portfolio securities at disadvantageous
prices or times since it may not be possible to liquidate a derivative position.

           The successful use of derivative transactions by the Fund is
dependent upon a Subadviser's ability to correctly anticipate trends in the
underlying asset. Hedging transactions are subject to risks; if a Subadviser
incorrectly anticipates trends in the underlying asset, the Fund may be in a
worse position than if no hedging had occurred. In addition, there may be
imperfect correlation between the Fund's derivative transactions and the
instruments being hedged.

Short Sales Against the Box


<PAGE>   36


           The Fund may also engage in short selling against the box as long as
no more than 15% of the value of the Fund's net assets is in deposits on short
sales against the box at any one time.

Hard Asset Securities

           The Fund may invest in equity securities of issuers which are
directly or indirectly engaged to a significant extent in the exploration,
development or distribution of one or more of the following: precious metals;
ferrous and non-ferrous metals; gas, petroleum, petrochemical and/or other
hydrocarbons; forest products; real estate and other basic non-agricultural
commodities (collectively, "Hard Assets"). The production and marketing of Hard
Assets may be affected by actions and changes in governments. In addition, Hard
Asset securities may be cyclical in nature. During periods of economic or
financial instability, the securities of some Hard Asset companies may be
subject to broad price fluctuations, reflecting the volatility of energy and
basic materials prices and the possible instability of supply of various Hard
Assets. In addition, some Hard Asset companies may also be subject to the risks
generally associated with extraction of natural resources, such as the risks of
mining and oil drilling, and the risks of the hazards associated with natural
resources, such as fire, drought, increased regulatory and environmental costs,
and others. Securities of Hard Asset companies may also experience greater price
fluctuations than the relevant Hard Asset. In periods of rising Hard Asset
prices, such securities may rise at a faster rate, and, conversely, in time of
falling Hard Asset prices, such securities may suffer a greater price decline.

Real Estate Securities

           Although the Fund will not invest in real estate directly, it may
invest in equity securities of real estate investment trusts ("REITs") and other
real estate industry companies or companies with substantial real estate
investments and therefore, the Fund may be subject to certain risks associated
with direct ownership of real estate and with the real estate industry in
general. These risks include, among others: possible declines in the value of
real estate; possible lack of availability of mortgage funds; extended vacancies
of properties; risks related to general and local economic conditions;
overbuilding; increases in competition, property taxes and operating expenses;
changes in zoning laws; costs resulting from the clean-up of, and liability to
third parties for damages resulting from, environmental problems; casualty or
condemnation losses; uninsured damages from floods, earthquakes or other natural
disasters; limitations on and variations in rents; and changes in interest
rates.

           REITs are pooled investment vehicles which invest primarily in income
producing real estate or real estate related loans or interests. REITs are
generally classified as equity REITs, mortgage REITs or hybrid REITs. Equity
REITs invest the majority of their assets directly in real property and derive
income primarily from the collection of rents. Equity REITs can also realize
capital gains by selling properties that have appreciated in value. Mortgage
REITs invest the majority of their assets in real estate mortgages and derive
income from the collection of interest payments. REITs are not taxed on income
distributed to shareholders provided they comply with several requirements of
Internal Revenue Code, as amended (the "Code").

Illiquid Securities

           The Fund may invest up to 15% of its net assets in securities that
are illiquid, in that they cannot be expected to be sold within seven days at
approximately the price at which they are valued. Due to the absence of an
active trading market, the Fund may experience difficulty in valuing or
disposing of illiquid securities. Each Subadviser will determine the liquidity
of the Fund's securities, under the supervision the Trust's trustees.

Restricted Securities, Non-Publicly Traded Securities and Rule 144A Securities

           Each Portfolio may invest in restricted securities and Rule 144A
securities. Restricted securities cannot be sold to the public without
registration under the Securities Act of 1933 ("1933 Act"). Unless registered
for sale, these securities can be sold only in privately negotiated transactions
or pursuant to an exemption from registration. Restricted securities are
generally considered illiquid and, therefore, subject to the Fund's 15%
limitation on illiquid securities.

           Non-publicly traded securities (including Rule 144A securities) may
involve a high degree of business and financial risk which may result in
substantial losses. The securities may be less liquid than publicly traded
securities. Although these securities may be resold in privately negotiated
transactions, the prices realized from these sales could be less than those
originally paid by the Fund. In particular, Rule 144A securities may be resold
only to qualified institutional buyers in accordance with Rule 144A under the
1933 Act. Unregistered securities may also be sold abroad pursuant to Regulation
S under the 1933 Act. Companies whose securities are not publicly traded are not
subject to the disclosure and other investor protection requirements that would
be applicable if their securities were publicly traded. Acting pursuant to
guidelines established by the Trustees of the Trust, some restricted securities
and Rule 144A securities may be considered liquid.


<PAGE>   37

When-Issued and Delayed-Delivery Transactions

           The Fund may invest without limitation in securities purchased on a
when-issued or delayed delivery basis. Although the payment and interest terms
of these securities are established at the time the purchaser enters into the
commitment, these securities may be delivered and paid for at a future date,
generally within 45 days. Purchasing when-issued securities allows the Fund to
lock in a fixed price or yield on a security it intends to purchase. However,
when the Fund purchases a when-issued security, it immediately assumes the risk
of ownership, including the risk of price fluctuation until the settlement date.

           The greater the Fund's outstanding commitments for these securities,
the greater the exposure to potential fluctuations in the net asset value of a
Fund. Purchasing when-issued securities may involve the additional risk that the
yield available in the market when the delivery occurs may be higher or the
market price lower than that obtained at the time of commitment. Although the
Fund may be able to sell these securities prior to the delivery date, it will
purchase when-issued securities for the purpose of actually acquiring the
securities, unless after entering into the commitment a sale appears desirable
for investment reasons. When required by SEC guidelines, the Fund will set aside
permissible liquid assets in a segregated account to secure its outstanding
commitments for when-issued securities.

Reverse Repurchase Agreements

           The Fund may also enter into reverse repurchase agreements with the
same parties with whom it may enter into repurchase agreements. Reverse
repurchase agreements involve the sale of securities held by the Fund pursuant
to its agreement to repurchase them at a mutually agreed upon date, price and
rate of interest. At the time the Fund enters into a reverse repurchase
agreement, it will establish and maintain a segregated account with an approved
custodian containing cash or liquid high-grade debt securities having a value
not less than the repurchase price (including accrued interest). The assets
contained in the segregated account will be marked-to-market daily and
additional assets will be placed in such account on any day in which the assets
fall below the repurchase price (plus accrued interest). The Fund's liquidity
and ability to manage its assets might be affected when it sets aside cash or
portfolio securities to cover such commitments. Reverse repurchase agreements
involve the risk that the market value of the securities retained in lieu of
sale may decline below the price of the securities the Fund has sold but is
obligated to repurchase. In the event the buyer of securities under a reverse
repurchase agreement files for bankruptcy or becomes insolvent, such buyer or
its trustee or receiver may receive an extension of time to determine whether to
enforce the Fund's obligation to repurchase the securities, and the Portfolio's
use of the proceeds of the reverse repurchase agreement may effectively be
restricted pending such decision. Reverse repurchase agreements are considered
to be borrowings under the Investment Company Act of 1940 (the "1940 Act").

Lending Portfolio Securities

           From time to time, the Fund may lend its portfolio securities to
brokers, dealers and other financial institutions needing to borrow securities
to complete certain transactions. In connection with such loans, the Fund will
receive collateral consisting of cash, U.S. Government securities or irrevocable
letters of credit. Such collateral will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities. The
Fund can increase its income through the investment of such collateral. The Fund
continues to be entitled to payments in amounts equal to the interest, dividends
or other distributions payable on the loaned security and receives interest on
the amount of the loan. Such loans will be terminable at any time upon specified
notice. The Fund might experience risk of loss if the institution with which it
has engaged in a portfolio loan transaction breaches its agreement with the
Fund.

Borrowing Money

           As a fundamental policy, the Fund is permitted to borrow to the
extent permitted under the 1940 Act. However, the Fund currently intends to
borrow money only for temporary or emergency purposes (but not for leverage or
the purchase of investments, except when entering into reverse repurchase
agreements as described above), in an amount up to 33-1/3% of the value of the
Fund's total assets (including the amount borrowed) valued at the time the
borrowing is made.

Non-Diversified Status

           The Fund is classified as non-diversified under the 1940 Act, which
means that the Fund is not limited by the 1940 Act in the proportion of its
assets that it may invest in securities of a single issuer. The Fund's
investments will be limited, however, in order to qualify as a "regulated
investment company" for purposes of the Code. To qualify, the Fund will comply
with certain requirements, including limiting its investments so that at the
close of each quarter of the taxable year (a) not more than 25% of the market
value of its total assets will be 

<PAGE>   38

invested in the securities of a single issuer, and (b) with respect to 50% of
the market value of its total assets, not more than 5% of the market value of
its total assets will be invested in the securities of a single issuer and the
Fund will not own more than 10% of the outstanding voting securities of a single
issuer. Being non-diversified means that the Fund may invest a greater
proportion of its assets in the obligations of a small number of issuers and, as
a result, may be subject to greater risk with respect to portfolio securities.
To the extent that the Fund assumes large positions in the securities of a small
number of issuers, its return may fluctuate to a greater extent than that of a
diversified company as a result of changes in the financial condition or in the
market's assessment of the issuers.

Portfolio Turnover

           The Fund will attempt to purchase securities with the intent of
holding them for investment but may purchase and sell portfolio securities
whenever the Adviser or a Subadviser believes it to be in the best interests of
the Fund. The Fund will not consider portfolio turnover rate a limiting factor
in making investment decisions consistent with its investment objective and
policies.

           The Fund's portfolio turnover rate for the year ended December 31,
1996 was approximately 137%. Higher turnover rates will generally result in
higher transaction costs to the Fund, as well as higher brokerage expenses and
higher levels of capital gains. The portfolio turnover rates for the Fund may
vary greatly from year to year and within a particular year.

MANAGEMENT OF THE TRUST

Trustees And Officers

           The business and affairs of the Trust are managed under the direction
of its Board of Trustees.

           The Board of Trustees sets and reviews policies regarding the
operation of the Trust whereas the officers perform the daily functions of the
Trust.

Investment Management Of The Fund

           The Adviser - Under the terms of the Investment Advisory Agreement,
Nationwide Advisory Services, Inc., Three Nationwide Plaza, Columbus, Ohio
43215, oversees the investment of the assets and, subject to the supervision of
the Trustees, provides various administrative services and supervises the daily
business affairs of the Fund.

           Subject to the supervision and direction of the Trustees, the Adviser
also determines the allocation of assets among the Subadvisers and evaluates and
monitors the performance of Subadvisers. The Adviser is also authorized to
select and place portfolio investments on behalf of the Fund; however, the
Adviser generally intends to limit its direct portfolio management to the
investment of a portion of the Fund's assets in cash or money market
instruments.

           The Adviser provides to the Fund investment management evaluation
services principally by performing initial due diligence on prospective
Subadvisers for the Fund and thereafter monitoring the performance of the
Subadvisers through quantitative and qualitative analysis as well as periodic
in-person, telephonic and written consultations with the Subadvisers. The
Adviser has responsibility for communicating performance expectations and
evaluations to the Subadvisers and ultimately recommending to the Trust's Board
of Trustees whether a Subadviser's contract should be renewed, modified or
terminated; however, the Adviser does not expect to recommend frequent changes
of Subadvisers. The Adviser will regularly provide written reports to the Board
of Trustees regarding the results of its evaluation and monitoring functions.
Although the Adviser will monitor the performance of the Subadvisers, there is
no certainty that any Subadviser or the Fund will obtain favorable results at
any given time.

           The Adviser, an Ohio corporation, is a wholly owned subsidiary of
Nationwide Life Insurance Company, which is wholly owned by Nationwide Financial
Services, Inc.(NFS). NFS, a holding company, has two classes of common stock
outstanding with different voting rights enabling Nationwide Corporation (the
holder of all outstanding Class B Common Stock) to control NFS. Nationwide
Corporation is also a holding company in the Nationwide Insurance Enterprise.
The Fund pays to the Adviser a fee at the annual rate of 1.00% of the Fund's
average daily net assets. The Adviser has voluntarily agreed to waive all or
part of its fees in order to limit the Fund's total operating expenses to not
more than 1.25% of the Fund's average daily net assets on an annual basis. These
fee waivers are voluntary and may be terminated at any time.

            The Subadvisers - Subject to the supervision of the Adviser and the
Trustees, the Subadvisers each manage separate portions of the Fund's assets in
accordance with the Fund's investment objective and policies. With regard to the
portion of the Fund's assets allocated to it, each Subadviser shall make
investment decisions for the Fund and in connection with such investment
decisions shall place purchase and sell orders for securities. No Subadviser
shall have any investment responsibility for any portion of the Fund's assets
not allocated to it for investment management. For the investment management
services they provide to the Fund, each Subadviser receives a fee from the
Adviser at the annual rate of .60% of the average daily net assets of the
portion of the Fund managed by that Subadviser.

           Below is a brief description of each of the subadvisers.

           The Dreyfus Corporation. Dreyfus, located at 200 Park Avenue, New
York, New York 10166, was formed in 1947 and serves as one of the Fund's

mutual fund assets. As of December 31, 1996, various subsidiaries of Mellon
provided non-investment services, such as custodial or administration services,
for approximately $1,046 billion in assets including approximately $57 billion
in mutual fund assets.

INVESTMENT IN FUND SHARES

           An insurance company purchases the shares of the Fund at the Fund's
net asset value using purchase payments received on Contracts issued by
Accounts. These Accounts are funded by shares of the Fund. There is no sales
charge. All shares are sold at net asset value.

           Shares of the Fund are currently sold only to separate accounts of
Nationwide Life Insurance Company and Nationwide Life and Annuity Insurance
Company, One Nationwide Plaza, Columbus, Ohio 43216, to fund the benefits under
variable insurance or annuity policies.

           All investments in the Fund are credited to the shareholder's account
in the form of full and fractional shares of the Fund (rounded to the nearest
1/1000 of a share). The Trust does not issue share certificates. Initial and
subsequent purchase payments allocated to the Fund are subject to the limits
applicable to the policies.

SHARE REDEMPTION

           An Account redeems shares to make benefit or surrender payments under
the terms of its Contracts. Redemptions are processed on any day on which the
Trust is open for business and are effected at net asset value next determined
after the redemption order, in proper form, is received by the Trust's transfer
agent, NIS.

           The net asset value per share of the Fund is determined once daily,
as of 4:00 P.M. on each business day the New York Stock Exchange is open and on
such other days as the Board determines and on any other day during which there
is a sufficient degree of trading in the Fund's portfolio securities that the
net asset value of the Fund is materially affected by changes in the value of
portfolio securities. The Trust will not compute net asset value on customary
national business holidays, including the following: Christmas, New Year's Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, and
Thanksgiving. The net asset value per share is calculated by adding the value of
all securities and other assets of a Fund, deducting its liabilities, and
dividing by the number of shares outstanding.

           In determining net asset value, portfolio securities listed on
national exchanges or actively traded in the over-the-counter market are valued
at the last quoted sale price; if there is no sale on that day, the securities
are valued at the prior day's closing price for exchange-traded securities or at
the quoted bid price for over-the-counter-traded securities. Other portfolio
securities are valued at the quoted prices obtained from an independent pricing
organization which employs a combination of methods, including among others, the
obtaining and comparison of market valuations from dealers who make markets and
deal in such securities and the comparison of valuations with those other
comparable securities in a matrix of such securities. The pricing service
activities and results are reviewed by an officer of the Trust. Securities for
which market quotations are not readily available are valued at fair value in
accordance with procedures adopted by the Board of Trustees. Expenses and fees
are accrued daily.

           The Trust may suspend the right of redemption only under the
following unusual circumstances:

            o when the New York Stock Exchange is closed (other than weekends
              and holidays) or trading is restricted;

            o when an emergency exists, making disposal of portfolio securities
              or the valuation of net assets not reasonably practicable; or

            o during any period when the Securities and Exchange Commission has
              by order permitted a suspension of redemption for the protection
              of shareholders.

NET INCOME AND DISTRIBUTIONS

           Substantially all of the net investment income, if any, of the Funds
will be declared as dividends in March, June, September, and December. In those
years in which sales of the Fund's portfolio securities result in net realized
capital gains, the Fund will distribute such gains to its shareholders in
January following a December declaration.


ADDITIONAL INFORMATION

<PAGE>   44

           Description Of Shares - The Declaration of Trust permits the Trustees
to issue an unlimited number of full and fractional shares of beneficial
interest of the Fund and to divide or combine such shares into a greater or
lesser number of shares without thereby changing the proportionate beneficial
interests in the Trust. Each share of the Fund represents an equal proportionate
interest in that Fund with each other share. The Trust reserves the right to
create and issue shares for a number of different Funds. In that case, the
shares of each Fund would participate equally in the earnings, dividends, and
assets of the particular Fund, but shares of all Funds would vote together in
the election of Trustees. Upon liquidation of a Fund, its shareholders are
entitled to share pro rata in the net assets of such Fund available for
distribution to shareholders.

           Voting Rights - Shareholders are entitled to one vote for each share
held. Shareholders may vote in the election or removal of Trustees and on other
matters submitted to meetings of shareholders. Although the sole shareholders of
the Trust are Nationwide Life Insurance Company and Nationwide Life and Annuity
Insurance Company, under current law, the life insurance company shareholders
are required to request voting instructions from policyholders and must vote
Trust shares held in proportion to the voting instructions received. No
amendment may be made to the Declaration of Trust without the affirmative vote
of a majority of the outstanding shares of the Trust. The Trustees may, however,
amend the Declaration of Trust without the vote or consent of shareholders to:

            o designate series of the Trust;

            o change the name of the Trust; or

            o supply any omission, cure, correct, or supplement any ambiguous,
              defective, or inconsistent provision to conform the Declaration of
              Trust to the requirements of applicable federal and state laws or
              regulations if they deem it necessary.

           Shares have no pre-emptive or conversion rights. Shares are fully
paid and nonassessable, except as set forth below. In regard to termination,
sale of assets, or changes of investment restrictions, the right to vote is
limited to the holders of shares of the particular Fund affected by the
proposal. When a majority is required, it means the lesser of 67% or more of the
shares present at a meeting when the holders of more than 50% of the outstanding
shares are present or represented by proxy, or more than 50% of the outstanding
shares.

           Shareholder Inquiries - All inquiries regarding the Fund should be
directed to the Trust at the telephone number or address shown on the cover page
of this Prospectus.

ADVERTISING PERFORMANCE FOR THE FUND

           The Fund may use historical performance in advertisements, sales
literature, and the prospectus. Such figures will include quotations of average
annual total return for the most recent one, five, and ten year periods (or the
life of the Fund if less). Average annual total return represents the rate
required each year for an initial investment to equal the redeemable value at
the end of the specific period. Average annual total return reflects
reinvestment of all distributions.

TAX STATUS

           The Trust's policy is to qualify as a regulated investment company
and to meet the requirements of Subchapter M of the Internal Revenue Code. The
Fund intends to distribute all its taxable net investment income and capital
gains to shareholders, and therefore, will not be required to pay any federal
income taxes.

           Because each Fund of the Trust is treated as a separate entity for
purposes of the regulated investment company provisions of the Code, the assets,
income, and distributions of the Fund are considered separately for purposes of
determining whether or not the Fund qualifies as a regulated investment company.
The Fund intends to comply with the diversification requirements currently
imposed by the Internal Revenue Service on separate accounts of insurance
companies as a condition of maintaining the tax-deferred status of the
Contracts. See the Statement of Additional Information for more specific
information.

           Dividends and interest received by the Fund may be subject to
withholding and other taxes imposed by foreign countries. However, tax
conventions between certain countries and the United States may reduce or
eliminate such taxes. Contract holders will bear the cost of foreign tax
withholding in the form of increased expenses to the Fund, but generally will
not be able to claim a foreign tax credit or deduction for foreign taxes paid by
the Fund by reason of the tax-deferred status of the Contracts.


<PAGE>   45


           The tax treatment of payments made by a separate account to a
Contract holder is described in the separate account prospectus.

SALE OF FUND SHARES

Shares of the Fund may be sold to life insurance company separate accounts (the
"Accounts") to fund the benefits of variable life insurance policies or annuity
contracts ("Contracts") issued by life insurance companies, as well as to other
open-end investment companies (each , a "Fund of Funds") created by Nationwide
Advisory Services, Inc. (the "Adviser"), the Fund's investment adviser. The
Accounts purchase shares of the Fund in accordance with variable account
allocation instructions received from owners of the Contracts. The Fund then
uses the proceeds to buy securities for its portfolio. The Adviser, together
with a group of subadvisers, manages the portfolio from day to day to accomplish
the Fund's investment objective. The types of investments and the way they are
managed depend on what is happening in the economy and the financial
marketplaces. Each Fund of Funds and Accounts, as a shareholder, has an
ownership in the Fund's investments. The Fund also offers to buy back (redeem)
shares of the Fund from the Fund of Funds or the Accounts at any time at net
asset value.

INVESTMENT OBJECTIVE AND POLICIES

Nationwide Income Fund (the "Fund") seeks to provide as high a level of income
as is consistent with reasonable concern for safety of principal. The Fund
intends to pursue its investment objective by investing at least 65% of its
assets, under normal market conditions, in investment grade corporate and U.S.
Government debt obligations. Under normal market conditions, the Fund may invest
up to 35% of its assets in cash or cash equivalents, commercial paper and
certain other money market instruments, as well as repurchase agreements
collateralized by these types of securities (collectively, "short-term money
market obligations"). For a further discussion of the types of debt obligations
in which the Fund may invest, see "INVESTMENT TECHNIQUES, CONSIDERATIONS AND
RISK FACTORS" below.

In addition, for temporary or emergency purposes, the Fund can invest up to 100%
of total assets in short-term money market obligations.

While there is careful selection and constant supervision by a group of
professional investment managers, there can be no guarantee that the Fund's
objective will be achieved. The investment objective of the Fund is not
fundamental and shareholder approval is not required to change the Fund's
investment objective.

Management of the Fund

Nationwide Advisory Services, Inc. (the "Adviser") has employed two subadvisers
(each, a "Subadviser") each of which will manage part of the Fund's portfolio.
Although the Adviser reserves the right to allocate and reallocate the assets
among the Subadvisers at any time, it is anticipated that each of the
Subadvisers will receive a substantially equal proportion of the funds that are
invested in the Fund and will generally retain such assets and any capital
appreciation attributable to them.

The Adviser has chosen the Subadvisers because they approach investing in debt
obligations in different ways. The Adviser has decided to employ a number of
Subadvisers because even successful investment managers may experience
fluctuations in performance which may be caused by factors or conditions that
affect the particular securities emphasized by that Subadviser or that may
impact its particular investment style. As a result of the diversification among
securities and styles, the Adviser expects to increase prospects for investment
return and to reduce market risk and volatility.

The following is a brief description of the investment strategies for each of
the Subadvisers:

NCM Capital Management Group, Inc. ("NCM Capital") manages fixed income
securities by selecting a diversified portfolio of investment grade issues in
which overall credit risk is minimized. NCM Capital established the average
maturity and duration of a portfolio based on the intermediate and longer-term
outlook of interest rates, the economy and the financial markets. No attempt is
made to manage portfolios based on daily or short-term fluctuations in interest
rates or economic statistics. 



<PAGE>   50

Subsequent to establishing the average maturity and duration of a portfolio, NCM
Capital determines which sectors of the fixed income market offer the most
attractive potential returns. Over a market cycle, individual sectors are either
emphasized or de-emphasized based on their relative value after analyzing the
current and prospective developments in the economy and the financial markets.
After determining the sector to be emphasized or de-emphasized, NCM Capital
selects the specific issues which offer the greatest potential returns over a
selected time horizon.

Smith Graham & Co. Asset Managers, L.P. ("Smith Graham") Smith Graham's
investment process centers around maximizing stable cash flows across the yield
curve. Cash flows in this context consist of coupon income on fixed income
securities, prepayments from mortgage securities and the reinvestment of income
and prepayments. Smith Graham begins by analyzing the characteristics that
determine performance and then utilizes proprietary software models to identify
the least expensive segments of the yield curve. Incremental performance is also
obtained by investing in undervalued sectors and undervalued securities.

INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS

Debt Obligations - Debt obligations in which the Fund may invest generally will
be investment grade debt obligations, although the Fund may invest up to 35% of
its assets in high-quality short-term money market obligations. The Fund's risk
and return potential depends in part on the maturity and credit-quality
characteristics of the underlying investments in its portfolio. In general, the
longer the maturity of a debt obligation, the greater its sensitivity to changes
in interest rates. Similarly, debt obligations issued by less creditworthy
entities tend to carry higher yields than those with higher credit ratings. The
market value of all debt obligations is also affected by changes in the
prevailing interest rates. Therefore, the market value of such instruments
generally reacts inversely to interest rate changes. If the prevailing interest
rates decrease, the market value of debt obligations generally increases. If the
prevailing interest rates increase, the market value of debt obligations
generally decreases.

Debt obligations in which the Fund may invest include: 1) bonds or bank
obligations rated in one of the four highest rating categories by any nationally
recognized statistical rating organization ("NRSRO") (e.g., Moody's Investors
Service, Inc. or Standard & Poor's Ratings Group); 2) U.S. government securities
(as described below); 3) commercial paper rated in one of the two highest
ratings categories of any NRSRO; 4) short-term bank obligations that are rated
in one of the two highest categories by any NRSRO, with respect to obligations
maturing in one year or less; 5) repurchase agreements relating to debt
obligations which the Fund could purchase directly; or 6) unrated debt
obligations which are determined by the Adviser or a Subadviser to be of
comparable quality.

Medium-quality obligations are obligations rated in the fourth highest rating
category by any NRSRO. Medium-quality securities, although considered
investment-grade, may have some speculative characteristics and may be subject
to greater fluctuations in value than higher-rated securities. In 


<PAGE>   51

addition, the issuers of medium-quality securities may be more vulnerable to
adverse economic conditions or changing circumstances than that of higher-rated
issuers.

All ratings are determined at the time of investment. Any subsequent rating
downgrade of a debt obligation will be monitored by the Adviser or a Subadviser
to consider what action, if any, the Fund should take consistent with its
investment objective; such event will not automatically require the sale of the
downgraded securities.

U.S. Government Securities - U.S. government securities are issued or guaranteed
by the U.S. government or its agencies or instrumentalities. Securities issued
by the government include U.S. Treasury obligations, such as Treasury bills,
notes, and bonds. Securities issued by government agencies or instrumentalities
include, but are not limited to, obligations of the following:

- -        the Federal Housing Administration, Farmers Home Administration, and
         the Government National Mortgage Association ("GNMA"), including GNMA
         pass-through certificates, whose securities are supported by the full
         faith and credit of the United States;
- -        the Federal Home Loan Banks and the Tennessee Valley Authority, whose
         securities are supported by the right of the agency to borrow from the
         U.S. Treasury;
- -        the Federal National Mortgage Association, whose securities are
         supported by the discretionary authority of the U.S. government to
         purchase certain obligations of the agency or instrumentality; and
- -        the Student Loan Marketing Association and the International Bank for
         Reconstruction and Development, whose securities are supported only by
         the credit of such agencies.

Although the U.S. government provides financial support to such U.S.
government-sponsored agencies or instrumentalities, no assurance can be given
that it will always do so. The U.S. government and its agencies and
instrumentalities do not guarantee the market value of their securities;
consequently, the value of such securities will fluctuate.

Mortgage- and Asset-Backed Securities - The Fund may purchase both mortgage- and
asset-backed securities. Mortgage-backed securities represent direct or indirect
participation in, or are secured by and payable from, mortgage loans secured by
real property, and include single- and multi-class pass-through securities and
collateralized mortgage obligations. Such securities may be issued or guaranteed
by U.S. government agencies or instrumentalities or by private issuers,
generally originators in mortgage loans, including savings and loan
associations, mortgage bankers, commercial banks, investment bankers, and
special purpose entities (collectively, "private lenders"). Mortgage-backed
securities issued by private lenders may be supported by pools of mortgage loans
or other mortgage-backed securities that are guaranteed, directly or indirectly,
by the U.S. government or one of its agencies or instrumentalities, or they may
be issued without any governmental guarantee of the underlying mortgage assets
but with some form of non-governmental credit enhancement.

Asset-backed securities have structural characteristics similar to
mortgage-backed securities. However, the underlying assets are not first-lien
mortgage loans or interests therein; rather they 


<PAGE>   52

include assets such as motor vehicle installment sales contracts, other
installment loan contracts, home equity loans, leases of various types of
property and receivables from credit card and other revolving credit
arrangements. Payments or distributions of principal and interest on
asset-backed securities may be supported by non-governmental credit enhancements
similar to those utilized in connection with mortgage-backed securities.

The yield characteristics of mortgage- and asset-backed securities differ from
those of traditional debt obligations. Among the principal differences are that
interest and principal payments are made more frequently on mortgage- and
asset-backed securities, usually monthly, and that principal may be prepaid at
any time because the underlying mortgage loans or other assets generally may be
prepaid at any time. As a result, if the Fund purchases these securities at a
premium, a prepayment rate that is faster than expected will reduce yield to
maturity, while a prepayment rate that is lower than expected will have the
opposite effect of increasing the yield to maturity. Conversely, if the Fund
purchases these securities at a discount, a prepayment rate that is faster than
expected will increase yield to maturity, while a prepayment rate that is slower
than expected will reduce yield to maturity. Accelerated prepayments on
securities purchased by the Fund at a premium also impose a risk of loss of
principal because the premium may not have been fully amortized at the time the
principal is prepaid in full. The market for privately issued mortgage- and
asset-backed securities is smaller and less liquid than the market for
government sponsored mortgage-backed securities.

The Fund may invest in stripped mortgage- or asset-backed securities, which
receive differing proportions of the interest and principal payments from the
underlying assets. The market value of such securities generally is more
sensitive to changes in prepayment and interest rates than is the case with
traditional mortgage- and asset-backed securities, and in some cases the market
value may be extremely volatile. With respect to certain stripped securities,
such as interest-only ("IO") and principal-only ("PO") classes, a rate of
prepayment that is faster or slower than anticipated may result in the Fund
failing to recover all or a portion of its investment, even though the
securities are rated investment grade.

Repurchase Agreements - The Fund may engage in repurchase agreement transactions
as long as the underlying securities are of the type that the Fund would be
permitted to purchase directly. Under the terms of a typical repurchase
agreement, the Fund would acquire an underlying debt obligation for a relatively
short period (usually not more than one week) subject to an obligation of the
seller to repurchase, and the Fund to resell, the obligation at an agreed upon
price and time, thereby determining the yield during the Fund's holding period.
The Fund will enter into repurchase agreements with respect to securities in
which it may invest with member banks of the Federal Reserve System or certain
non-bank dealers. Under each repurchase agreement the selling institution will
be required to maintain the value of the securities subject to the repurchase
agreement at not less than their repurchase price. Repurchase agreements could
involve certain risks in the event of default or insolvency of the other party,
including possible delays or restrictions upon a Fund's ability to dispose of
the underlying securities. The Adviser or a Subadviser, acting under the
supervision of the Board of Trustees, reviews the creditworthiness of those
banks and non-bank dealers with which 


<PAGE>   53

the Fund enters into repurchase agreements to evaluate these risks. See
"Repurchase Agreements" in the Statement of Additional Information.

Bank Obligations - The Fund may invest in bank obligations, such as certificates
of deposit, banker's acceptances, and time deposits of domestic or foreign banks
and their subsidiaries and branches (only if the time deposits are denominated
in U.S. dollars), and domestic savings and loan associations. While these bank
obligations will be issued by institutions whose accounts are insured by the
Federal Deposit Insurance Corporation ("FDIC"), the Fund may invest in the
obligations in amounts in excess of the FDIC insurance coverage (currently
$100,000 per account).

When-Issued Securities - The Fund may invest without limitation in securities
purchased on a when-issued or delayed delivery basis. Although the payment and
interest terms of these securities are established at the time the purchaser
enters into the commitment, these securities may be delivered and paid for at a
future date, generally within 45 days (for mortgage-backed securities, the
delivery date may extend to as long as 120 days). Purchasing when-issued
securities allows the Fund to lock in a fixed price or yield on a security it
intends to purchase. However, when the Fund purchases a when-issued security, it
immediately assumes the risk of ownership, including the risk of price
fluctuation until the settlement date.

The greater the Fund's outstanding commitments for these securities, the greater
the exposure to potential fluctuations in the net asset value of a Fund.
Purchasing when-issued securities may involve the additional risk that the yield
available in the market when the delivery occurs may be higher or the market
price lower than that obtained at the time of commitment. Although the Fund may
be able to sell these securities prior to the delivery date, it will purchase
when-issued securities for the purpose of actually acquiring the securities,
unless after entering into the commitment a sale appears desirable for
investment reasons. When required by guidelines issued by the Securities and
Exchange Commission, the Fund will set aside permissible liquid assets in a
segregated account to secure its outstanding commitments for when-issued
securities.

Lending Portfolio Securities - From time to time, the Fund may lend its
portfolio securities to brokers, dealers and other financial institutions
needing to borrow securities to complete certain transactions. In connection
with such loans, the Fund will receive collateral consisting of cash, U.S.
Government securities or irrevocable letters of credit. Such collateral will be
maintained at all times in an amount equal to at least 100% of the current
market value of the loaned securities. The Fund can increase its income through
the investment of such collateral. The Fund continues to be entitled to payments
in amounts equal to the interest, dividends or other distributions payable on
the loaned security and receives interest on the amount of the loan. Such loans
will be terminable at any time upon specified notice. The Fund might experience
risk of loss if the institution with which it has engaged in a portfolio loan
transaction breaches its agreement with the Fund.

Borrowing Money - The Fund may borrow money from banks limited by any investment
restrictions to 33 1/3% of its total assets. However, the Fund currently intends
to borrow money only for temporary or emergency purposes (but not for leverage
or the purchase of investments), in an amount 


<PAGE>   54

up to 5% of the value of the Fund's total assets (including the amount borrowed)
valued at the time the borrowing is made.


Portfolio Turnover

The Fund will attempt to purchase securities with the intent of holding them for
investment but may purchase and sell portfolio securities whenever the Adviser
or a Subadviser believes it to be in the best interests of the Fund. The Fund
will not consider portfolio turnover rate a limiting factor in making investment
decisions consistent with its investment objective and policies.

The portfolio turnover rate for the Fund is not expected to exceed 150%. Higher
turnover rates will generally result in higher transaction costs to the Fund, as
well as higher brokerage expenses and higher levels of capital gains. The
portfolio turnover rates for the Fund may vary greatly from year to year and
within a particular year.

MANAGEMENT OF THE TRUST

Trustees and Officers

The business and affairs of the Trust are managed under the direction of its
Board of Trustees.

The Board of Trustees sets and reviews policies regarding the operation of the
Trust, whereas the officers perform the daily functions of the Trust.

Investment Management of the Fund

The Adviser - Under the terms of the Investment Advisory Agreement, Nationwide
Advisory Services, Inc., One Nationwide Plaza, Columbus, Ohio 43216, oversees
the investment of the assets for the Fund and supervises the daily business
affairs of the Fund. Subject to the supervision and direction of the Trustees,
the Adviser also determines the allocation of assets among the Subadvisers and
evaluates and monitors the performance of Subadvisers. The Adviser is also
authorized to select and place portfolio investments on behalf of the Fund;
however, the Adviser does not intend to do so at this time.

The Adviser provides to the Fund investment management evaluation services
principally by performing initial due diligence on prospective Subadvisers for
the Fund and thereafter monitoring the performance of the Subadvisers through
quantitative and qualitative analysis as well as periodic in-person, telephonic
and written consultations with the Subadvisers. The Adviser has responsibility
for communicating performance expectations and evaluations to the Subadvisers
and ultimately recommending to the Trust's Board of Trustees whether a
Subadviser's contract should be renewed, modified or terminated; however, the
Adviser does not expect to recommend frequent changes of Subadvisers. The
Adviser will regularly provide written reports to the Board of Trustees
regarding the results of its evaluation and monitoring functions. Although the
Adviser will monitor the 



<PAGE>   55

performance of the Subadvisers, there is no certainty that any Subadviser or the
Fund will obtain favorable results at any given time.

   
The Adviser, an Ohio corporation, is a wholly owned subsidiary of Nationwide
Life Insurance Company, which is owned by Nationwide Financial Services, Inc. 
(NFS). NFS, a holding company, has two classes of common stock outstanding with 
different voting rights enabling Nationwide Corporation (the holder of all the 
outstanding Class B Common Stock) to control NFS. Nationwide Corporation is 
also a holding company in the Nationwide Insurance Enterprise. The Fund pays to 
the Adviser a fee at the annual rate of 0.45% of the Fund's average daily net 
assets. 
    

The Subadvisers - Subject to the supervision of the Adviser and the Trustees,
the Subadvisers each manage separate portions of the Fund's assets in accordance
with the Fund's investment objective and policies. With regard to the portion of
the Fund's assets allocated to it, each Subadviser shall make investment
decisions for the Fund and in connection with such investment decisions shall
place purchase and sell orders for securities. No Subadviser shall have any
investment responsibility for any portion of the Fund's assets not allocated to
it for investment management. For the investment management services they
provide to the Fund, each Subadviser receives an annual fee from the Adviser
based on the average daily net assets of the portion of the Fund managed by that
Subadviser as specified below:

         Subadvisory Fees                         Average Daily Net Assets
              0.25%                               on the first $100 million
              0.15%                              on assets in excess of $100
                                                           million

Other Services

Under the terms of an Administrative Services Agreement, the Adviser also
provides various administrative and accounting services, including daily
valuation of each Fund's shares, preparation of financial statements, taxes, and
regulatory reports. For these services the Fund pays to the Adviser a fee at the
annual rate of 0.10% of the Fund's average daily net assets.

The Transfer and Dividend Disbursing Agent, Nationwide Investors Services, Inc.,
("NIS"), One Nationwide Plaza, Columbus, Ohio 43216, serves as transfer agent
and dividend disbursing agent for the Trust. NIS is a wholly owned subsidiary of
the Adviser.

INVESTMENT IN FUND SHARES

An insurance company may purchase the shares of the Fund at the Fund's net asset
value using purchase payments received on Contracts issued by Accounts. These
Accounts are funded by shares of the Fund. Funds of Funds may also purchase
shares of the Fund for their portfolios. There is no sales charge. All shares
are sold at net asset value.

Shares of the Fund are currently sold only to separate accounts of Nationwide
Life Insurance Company and its wholly owned subsidiary Nationwide Life and
Annuity Insurance Company to fund the benefits under the Contract and to
affiliated Fund of Funds. The address for each of these entities is One
Nationwide Plaza, Columbus, Ohio 43216,

All investments in the Fund are credited to the shareholder's account in the
form of full and fractional shares of the Fund (rounded to the nearest 1/1000 of
a share). The Trust does not issue share certificates. Initial and subsequent
purchase payments allocated to the Fund are subject to the limits applicable to
the Contracts.

SHARE REDEMPTION

Redemptions are processed on any day on which the Trust is open for business and
are effected at net asset value next determined after the redemption order, in
proper form, is received by the Trust's transfer agent, NIS.

The net asset value per share of the Fund is determined once daily, as of 4:00
P.M. on each business day the New York Stock Exchange is open and on such other
days as the Board determines and on any other day during which there is a
sufficient degree of trading in the Fund's portfolio securities that the net
asset value of the Fund is materially affected by changes in the value of
portfolio securities. The Trust will not compute net asset value on customary
national business holidays, including the following: Christmas, New Year's Day,
Presidents' Day, Good Friday, Memorial Day, Independence 



<PAGE>   58

Day, Labor Day, and Thanksgiving Day. The net asset value per share is
calculated by adding the value of all securities and other assets of a Fund,
deducting its liabilities, and dividing by the number of shares outstanding.

In determining net asset value, portfolio securities listed on national
exchanges or actively traded in the over-the-counter market are valued at the
last quoted sale price; if there is no sale on that day, the securities are
valued at the prior day's closing price for exchange-traded securities or at the
quoted bid price for over-the-counter-traded securities. Other portfolio
securities are valued at the quoted prices obtained from an independent pricing
organization which employs a combination of methods, including among others, the
obtaining and comparison of market valuations from dealers who make markets and
deal in such securities and the comparison of valuations with those of other
comparable securities in a matrix of such securities. The pricing service
activities and results are reviewed by an officer of the Trust. Securities for
which market quotations are not readily available are valued at fair value in
accordance with procedures adopted by the Board of Trustees.
Expenses and fees are accrued daily.

The Trust may suspend the right of redemption only under the following unusual
circumstances:

       o when the New York Stock Exchange is closed (other than weekends and
         holidays) or trading is restricted;

       o when an emergency exists, making disposal of portfolio securities or
         the valuation of net assets not reasonably practicable; or

       o during any period when the Securities and Exchange Commission has by
         order permitted a suspension of redemption for the protection of
         shareholders.

NET INCOME AND DISTRIBUTIONS

Substantially all of the net investment income, if any, of the Funds will be
paid as dividends in March, June, September, and December. In those years in
which sales of the Fund's portfolio securities result in net realized capital
gains, the Fund will distribute such gains to its shareholders with the December
dividend.

ADDITIONAL INFORMATION

Description of Shares - The Declaration of Trust permits the Trustees to issue
an unlimited number of full and fractional shares of beneficial interest of the
Fund and to divide or combine such shares into a greater or lesser number of
shares without thereby changing the proportionate beneficial interests in the
Trust. Each share of the Fund represents an equal proportionate interest in that
Fund with each other share. The Trust reserves the right to create and issue
shares from a number of different Funds. In that case, the shares of each Fund
would participate equally in the earnings, dividends, and assets of the
particular Fund, but shares of all Funds would vote together in the 




<PAGE>   59

election of Trustees. Upon liquidation of a Fund, its shareholders are entitled
to share pro rata in the net assets of such Fund available for distribution to
shareholders.

Voting Rights - Shareholders are entitled to one vote for each share held.
Shareholders may vote in the election or removal of Trustees and on other
matters submitted to meetings of shareholders. No amendment may be made to the
Declaration of Trust without the affirmative vote of a majority of the
outstanding shares of the Trust. The sole shareholders of the Fund initially
will be the affiliated Funds of Funds and Nationwide Life Insurance Company. The
Trustees may, however, amend the Declaration of Trust without the vote or
consent of shareholders to:

       o designate series of the Trust;

       o change the name of the Trust; or

       o supply any omission, cure, correct, or supplement any ambiguous,
         defective, or inconsistent provision to conform the Declaration of
         Trust to the requirements of applicable federal and state laws or
         regulations if they deem it necessary.

Shares have no pre-emptive or conversion rights. Shares are fully paid and
nonassessable, except as set forth below. In regard to termination, sale of
assets, or changes of investment restrictions, the right to vote is limited to
the holders of shares of the particular Fund affected by the proposal. When a
majority is required, it means the lesser of 67% or more of the shares present
at a meeting when the holders of more than 50% of the outstanding shares are
present or represented by proxy, or more than 50% of the outstanding shares.

Shareholder Inquiries - All inquiries regarding the Fund should be directed to
the Trust at the telephone number or address shown on the cover page of this
Prospectus.

PERFORMANCE ADVERTISING FOR THE FUND

The Fund may use historical performance in advertisements, sales literature, and
the prospectus. Such figures will include quotations of average annual total
return for the most recent one, five, and ten year periods (or the life of the
Fund if less). Average annual total return represents the rate required each
year for an initial investment to equal the redeemable value at the end of the
specific period. Average annual total return reflects reinvestment of all
distributions.

TAX STATUS

The Trust's policy is to qualify as a regulated investment company and to meet
the requirements of Subchapter M of the Internal Revenue Code (the "Code"). The
Fund intends to distribute all its taxable net investment income and capital
gains to shareholders, and therefore, will not be required to pay any federal
income taxes.

<PAGE>   60

Because each Fund of the Trust is treated as a separate entity for purposes of
the regulated investment company provisions of the Code, the assets, income, and
distributions of the Fund are considered separately for purposes of determining
whether or not the Fund qualifies as a regulated investment company. The Fund
intends to comply with the diversification requirements currently imposed by the
Internal Revenue Service on separate accounts of insurance companies as a
condition of maintaining the tax-deferred status of the Contracts. See the
Statement of Additional Information for more specific information.

  The tax treatment of payments made by an Account to a Contractholder is
described in the separate account prospectus.

GENERAL INFORMATION AND HISTORY

   
         Nationwide Separate Accounts Trust is an open-end investment company
organized under the laws of Massachusetts, by a Declaration of Trust, dated June
30, 1981, as amended October 22, 1981, September 3, 1982, April 16, 1987, May 1,
1992, August 9, 1995, November 3, 1995, and October 17, 1996. The Trust offers
shares in fifteen separate mutual funds, each with its own investment 
objective. This Statement of Additional Information discussion further six of 
those funds -- The Total Return Fund, The Capital Appreciation Fund, the 
Government Bond Fund, the Money Market Fund, the Small Company Fund and the 
Income Fund (collectively, the "Funds" and individually, a "Fund").
    

INVESTMENT OBJECTIVES AND POLICIES

   
         The following information supplements the discussion of the Funds'
investment objectives and policies discussed in the Prospectuses. Defined terms 
used in this Statement of Additional Information, unless otherwise defined 
herein, have the meaning assigned to them in the relevant Prospectus.
    

         The investment policies and types of permitted investments described
here may be changed without prior approval by, or notice to, the shareholders.
There is no guarantee that the objectives will be realized.


<PAGE>   63


- --TOTAL RETURN FUND

         This Fund's investment objective is to obtain a reasonable, long term
total return on invested capital from a flexible combination of dividend return
and capital gains. The Fund seeks to achieve its objective through investments
in common stocks, convertible issues, money market instruments, and bonds, with
a primary emphasis on common stocks.

         While it is the intention of the Fund to invest in common stocks or in
issues convertible to common stock, there are no restrictive provisions covering
the proportion of one or another class of securities that may be held, or other
restriction, other than those stated in the investment restrictions.

- --CAPITAL APPRECIATION FUND

         The Fund is designed for investors who are interested in long-term
growth. The Fund seeks to meet its objectives primarily through a diversified
portfolio of the common stock of companies which the investment manager
determines have a better-than-average potential for sustained capital growth
over the long term.

         While it is the intention of the Fund to invest in common stocks or in
issues convertible to common stock, there are no restrictive provisions covering
the proportion of one or another class of securities that may be held, or other
restriction, other than those stated in the investment restrictions.

         The investment manager will focus mainly on a company's or industry's
potential for long term growth, with dividend and interest income being
secondary in importance. The manager's evaluation of a company or industry will
be based more on probable future earnings, relative financial strength and
competitive position. The manager believes this approach will provide a greater
return potential over the long run than simply seeking current dividend or
interest income. The Fund's portfolio will not be limited to any particular type
of company or industry.

- --GOVERNMENT BOND FUND

         The investment objective of the Government Bond Fund is to provide as
high a level of income as is consistent with the preservation of capital. It
seeks to achieve its objective by investing in a diversified portfolio of
securities issued or backed by the U.S. Government, it agencies or
instrumentalities.

         These securities are of varying types which include but are not limited
to:

         Treasury Notes And Bonds - These are direct obligations of the U.S.
Government. New issues of notes mature in one to ten years while bonds generally
have a maturity of ten years or more.

         Treasury Bills - These are direct obligations of the U.S. Government
backed by the full faith and credit of the United States and mature in one year
or less.

         Securities Issued By Instrumentalities of the U.S. Government - These
securities are issued by federally-chartered instrumentalities. Some of these
securities are guaranteed by the United States Treasury or are supported by the
issuer's right to borrow from the Treasury and are backed by the credit of the
federal instrumentality itself.


                                       2


<PAGE>   64


Some of these instrumentalities (listed for example purposes only) are:

                               Bank for Cooperatives (COOP)
                               Federal Home Loan Banks (FHLB)
                               Federal National Mortgage Association (FNMA)
                               Government National Mortgage Association (GNMA)
                               Tennessee Valley Authority (TVA)
                               Farmers Home Administration (FHA)

The Government Bond Fund will normally invest at least 65% of its assets in
bonds issued by the U.S. Government, and its agencies and instrumentalities.
These bonds pay interest at regular intervals, usually semi-annually, and pay
principal at maturity.

The Government Bond Fund may invest up to 35% of its assets in zero coupon
securities and up to 20% of its assets in securities purchased on a
"when-issued" or on a "delayed-delivery" basis, provided those securities are
issued or backed by the U.S. Government, its agencies or instrumentalities (for
a further description of "when-issued" or "delayed-delivery" transactions, see
"Income Fund -- When-Issued Securities and Delayed-Delivery Transactions"
below). The Government Bond Fund may also enter into repurchase agreements in
any of the securities described above (for a description of repurchase
agreements, see "Income Fund - Repurchase Agreements" below).

The Government Bond Fund may invest up to 35% of its assets in mortgage-backed
securities. Mortgage-backed securities represent direct or indirect
participation in, or are secured by and payable from, mortgage loans secured by
real property, and include single- and multi-class pass-through securities and
collateralized mortgage obligations. The securities purchased by the Government
Bond Fund are issued or guaranteed by U.S. government agencies or
instrumentalities.

Government-related entities may also create mortgage loan pools offering
pass-through investments where the mortgages underlying these securities may be
alternative mortgage instruments, that is, mortgage instruments whose principal
or interest payments may vary or whose terms to maturity may be shorter than
previously customary. As new types of mortgage-related securities are developed
and offered to investors, the Fund, consistent with its investment objective and
policies, may consider making investments in such new types of securities.

The yield characteristics of mortgage-backed securities differ from those of
traditional debt obligations. Among the principal differences are that interest
and principal payments are made more frequently on mortgage-backed securities,
usually monthly, and that principal may be prepaid at any time because the
underlying mortgage loans generally may be prepaid at any time. As a result, if
the Fund purchases these securities at a premium, a prepayment rate that is
faster than expected will reduce yield to maturity, while a prepayment rate that
is lower than expected will have the opposite effect of increasing the yield to
maturity. Conversely, if the Fund purchases these securities at a discount, a
prepayment rate that is faster than expected will increase yield to maturity,
while a prepayment rate that is slower than expected will reduce yield to
maturity. Accelerated prepayments on securities purchased by the Fund at a
premium also impose a risk of loss of principal because the premium may not have
been fully amortized at the time the principal is prepaid in full.

The Government Bond Fund will normally invest no more than 20% of its assets in
repurchase agreements or in U.S. Government securities maturing in less than one
year. For temporary defensive purposes, however the Fund may invest up to 100%
of its assets in these securities.

   
There is a minimal credit risk involved in the purchase of U.S. Government or
U.S. Government guaranteed securities. Securities issued by U.S. Government
agencies or instrumentalities, while perhaps having the implicit backing of the
U.S. Government, may not have an explicit guarantee of the payment of principal
and interest.
    

The value of shares of the Government Bond Fund will vary inversely with changes
in interest rates. As with any fixed income investment, interest rate risk does
exist; i.e., when interest rates decline, the market value of a portfolio can be
expected to rise; conversely, when interest rates rise, the market value of the
portfolio can be expected to fall. While the Government Bond Fund will engage in
portfolio trading to manage this risk (i.e., shortening the average maturity of
the portfolio in anticipation of a rise in interest rates so as to minimize
depreciation of principal, or lengthening the portfolio in anticipation of a
decline in interest rates so as to maximize appreciation of capital) there is no
assurance that capital will be preserved. Thus, the Government Bond Fund is
designed for those willing to accept market fluctuations to obtain income.

- --MONEY MARKET FUND

The investment objective of this Fund is to seek as high a level of current
income as it considered consistent with the preservation of capital and
liquidity through investments in a portfolio of money market instruments with
remaining maturities of 397 days or less. The Fund seeks to achieve its
objective by investing primarily in instruments receiving a rating in one of the
two highest categories by the following six nationally recognized statistical
rating organizations ("NRSROs"): Duff and Phelps, Inc. ("D&P"), Fitch Investors
Services, Inc. ("Fitch"), Moody's Investors Service Inc. ("Moody's"), Standard &
Poor's Ratings Group ("Standard & Poor's"), IBCA Limited and its affiliate, IBCA
Inc. ("IBCA"), and Thomson Bank Watch ("Thomson"). See Appendix A for a further
description of the NRSRO ratings.

The Fund may invest in the following instruments:

                  -- obligations issued or guaranteed as to interest and
                  principal by the U.S. government, its agencies, or
                  instrumentalities, or any federally chartered corporation.

                  -- repurchase agreements, subject to the restrictions set
                  forth under "Investment Restrictions." Potential risks
                  associated with investment in repurchase agreements are
                  twofold: (a) in the event of default of an issuer and a
                  decrease in the value of the underlying securities below the
                  repurchase price, the Fund could suffer a loss, and (b) in the
                  event of an issuer's bankruptcy, the Fund's ability to dispose
                  of underlying securities could be delayed. (For a further
                  description, see "Income Fund --Repurchase Agreements" below.)

                  -- obligations of banks which at the date of investment are
                  rated A2 or better by IBCA or TBW1 by Thomson. Obligations of
                  savings and loan associations (including certificates of
                  deposit and bankers' acceptances) which at the date of
                  investment have capital, surplus, and undivided profits (as of
                  the date of their most recently published financial
                  statements) in excess of $100 million; and obligations of
                  other banks or savings and loan associations if such
                  obligations are insured by the Federal Deposit Insurance
                  Corporation, provided that not more than 10% of the Fund's
                  total assets shall be invested in such insured obligations.

                  -- commercial paper which at the date of investment is rated
                  Duff 1 or Duff 2, by D&F, F-1 or F-2 by Fitch, P-1 or P-2 by
                  Moody's, or A-1 or A-2 by Standard & Poor's, or if not rated,


                                       4


<PAGE>   66


                  is issued and guaranteed as to payment of principal and
                  interest by companies which at the date of investment have an
                  outstanding debt issue rated AA or better by D&F, AA or better
                  by Fitch, Aa or better by Moody's, or AA or better by Standard
                  & Poor's.

                  -- up to 5% of its total assets in commercial paper which at
                  the date of investment is rated F-2 by Fitch, Duff 2 by D&P,
                  P-2 by Moody's, or A-2 by Standard and Poor's. However, the
                  Fund is limited as to the amount it may invest in the
                  commercial paper of a single issuer to the greater of 1% of
                  the Fund's total assets or $1 million.

                  -- short-term (maturity in 397 days or less) corporate
                  obligations which at the date of investment are rated AA or
                  better by D&F, AA or better by Fitch, Aa or better by Moody's,
                  or AA or better by Standard & Poor's.

                  -- bank loan participation agreements representing
                  corporations and banks having a short-term rating, at the date
                  of investment, of F-1 or F-2 by Fitch, Duff 1 or Duff 2 by
                  D&P, P-1 or P-2 by Moody's or A-1 or A-2 by Standard & Poor's,
                  under which the Fund will look to the creditworthiness of the
                  lender bank, which is obligated to make payments of principal
                  and interest on the loan, as well as to creditworthiness of
                  the borrower.

   
All the assets of the Fund will be invested generally in obligations with
remaining maturities of 397 days or less and which generally will be held to
maturity. The Fund will, to the extent feasible, make portfolio investments
primarily in anticipation of, or in response to, changing economic and financial
conditions. The Fund will attempt to maximize the return on its investments
through careful analysis of a wide range of investments available and different
yield relationships existing among various sectors of the market. The average
dollar weighted maturity of the Fund's investments may not exceed 90 days. There
can be no assurance that the Fund's investment objective will be achieved. 
    

The Fund may invest in the securities of foreign corporate and governmental
issuers and in the securities of foreign branches of U.S. banks, such as
negotiable certificates of deposit (Eurodollars) in U.S. dollar denominations
which at the date of investment are rated A1 or A2 by IBCA or TBW1 by Thomson.
Because of this, investment in the Fund involves risks that are different in
some respects from an investment in a fund which invests only in debt
obligations of U.S. domestic issuers. Such risks may include future political
and economic developments, the possible imposition of foreign withholding taxes
on interest income payable on the securities held in the portfolio, possible
seizure or nationalization of foreign deposits, the possible establishment of
exchange controls, or the adoption of other foreign governmental restrictions
which might adversely affect the payment of principal and interest on securities
in the portfolio.

   
Investment Policies Relating to the Capital Appreciation Fund, the Total Return 
Fund, the Government Bond Fund and the Money Market Fund.

BORROWING. Each of the Capital Appreciation Fund, the Total Return Fund, the 
Government Bond Fund and the Money Market Fund may borrow money only for 
temporary or emergency purposes or for the clearance of transactions. This 
borrowing will be limited to an amount of 5% of the value of the Fund's total 
assets (including the amount borrowed) valued at the time the borrowing is 
made. In such situations, either the custodian will segregate the pledged 
assets for the benefit of the lender or arrangements will be made with a 
suitable subcustodian, which may include the lender.

SECURITIES OF NON-AFFILIATED INVESTMENT COMPANIES. Each of the Capital 
Appreciation Fund, the Total Return Fund, the Government Bond Fund and the 
Money Market Fund may invest in other investment companies. Investing through 
such vehicles may involve frequent or layered fees or expenses and is subject 
to limitations under the 1940 Act. Each of these Funds has adopted a policy 
stating that it will not invest more than 10% of its assets in shares of 
investment companies or more than 5% of its assets in any one investment 
company; in addition, each Fund will not purchase more than 3% of the voting 
stock of the acquired investment company.
    

   
- -- INCOME FUND
    

         The Income Fund seeks to provide as high a level of income as is
consistent with reasonable concern for safety of principal. The Fund intends to
pursue its investment objective by investing at least 65% of its assets, under
normal market conditions, in investment grade corporate and U.S. Government debt
obligations. The Fund may invest the remainder of its portfolio in high quality
short-term money market obligations.

DEBT OBLIGATIONS. Debt obligations are subject to the risk of an issuer's
inability to meet principal and interest payments on its obligations ("credit
risk") and are subject to price volatility due to such factors as interest rate
sensitivity, market perception of the creditworthiness of the issuer, and
general market liquidity 


                                       5


<PAGE>   67


("market risk"). Lower-rated securities are more likely to react to developments
affecting market and credit risk than are more highly rated securities, which
react primarily to movements in the general level of interest rates.

         RATINGS AS INVESTMENT CRITERIA. The Income Fund may invest in
high-quality and medium-quality debt obligations which are characterized as such
based on their ratings by nationally recognized statistical rating organizations
("NRSROs"). In general, the ratings of NRSROs represent the opinions of these
agencies as to the quality of securities that they rate. Such ratings, however,
are relative and subjective, and are not absolute standards of quality and do
not evaluate the market value risk of the securities. These ratings are used by
the Fund as initial criteria for the selection of portfolio securities, but the
Fund will also rely upon the independent advice of the Subadvisers to evaluate
potential investments. Among the factors that will be considered are the
long-term ability of the issuer to pay principal and interest and general
economic trends. The Appendix to this Statement of Additional Information
contains further information about the rating categories of NRSROs and their
significance.

   
Subsequent to its purchase by the Income Fund, an issue of securities may cease
to be rated or its rating may be reduced below the minimum required for purchase
by the Income Fund. In addition, it is possible that an NRSRO might not change
its rating of a particular issue to reflect subsequent events. None of these
events generally will require sale of such securities, but the Income Fund's
Subadviser will consider such events in its determination of whether the
Income Fund should continue to hold the securities. In addition, to the extent
that the ratings change as a result of changes in such organizations or their
rating systems, or due to a corporate reorganizations, the Income Fund will
attempt to use comparable ratings as standards for its investments in accordance
with its investment objective and policies.
    

MONEY MARKET INSTRUMENTS. The Income Fund may invest in certain types of money
market instruments which may include the following types of instruments:

                           -- obligations issued or guaranteed as to interest
                  and principal by the U.S. government, its agencies, or
                  instrumentalities, or any federally chartered corporation;

                           -- repurchase agreements;

                           -- certificates of deposit, time deposits and
                  bankers' acceptances issued by domestic banks (including their
                  branches located outside the United States and subsidiaries
                  located in Canada), domestic branches of foreign banks,
                  savings and loan associations and similar institutions

                           -- commercial paper, which are short-term unsecured
                  promissory notes issued by corporations in order to finance
                  their current operations. Generally the commercial paper will
                  be rated within the top two rating categories by an NRSRO, or
                  if not rated, is issued and guaranteed as to payment of
                  principal and interest by companies which at the date of
                  investment have a high quality outstanding debt issue;


                                       6


<PAGE>   68


                           -- high quality short-term (maturity in 397 days or
                  less) corporate obligations;

                           -- bank loan participation agreements representing
                  corporations and banks having a high quality short-term
                  rating, at the date of investment, and under which the Fund
                  will look to the creditworthiness of the lender bank, which is
                  obligated to make payments of principal and interest on the
                  loan, as well as to creditworthiness of the borrower.

MORTGAGE- AND ASSET-BACKED SECURITIES - The Income Fund may purchase both
mortgage- and asset-backed securities. Mortgage-backed securities represent
direct or indirect participation in, or are secured by and payable from,
mortgage loans secured by real property, and include single- and multi-class
pass-through securities and collateralized mortgage obligations. Such securities
may be issued or guaranteed by U.S. government agencies or instrumentalities or
by private issuers, generally originators in mortgage loans, including savings
and loan associations, mortgage bankers, commercial banks, investment bankers,
and special purpose entities (collectively, "private lenders"). Mortgage-backed
securities issues by private lenders may be supported by pools of mortgage loans
or other mortgage-backed securities that are guaranteed, directly or indirectly,
by the U.S. government or one of its agencies or instrumentalities, or they may
be issued without any governmental guarantee of the underlying mortgage assets
but with some form of non-governmental credit enhancement. These credit
enhancements may include letters of credit, reserve funds,
overcollateralization, or guarantees by third parties.

Private lenders or government-related entities may also create mortgage loan
pools offering pass-through investments where the mortgages underlying these
securities may be alternative mortgage instruments, that is, mortgage
instruments whose principal or interest payments may vary or whose terms to
maturity may be shorter than previously customary. As new types of
mortgage-related securities are developed and offered to investors, the Fund,
consistent with its investment objective and policies, may consider making
investments in such new types of securities.


Asset-backed securities have structural characteristics similar to
mortgage-backed securities. However, the underlying assets are not first-lien
mortgage loans or interests therein; rather they include assets such as motor
vehicle installment sales contracts, other installment loan contracts, home
equity loans, leases of various types of property and receivables from credit
card and other revolving credit arrangements. Payments or distributions of
principal and interest on asset-backed securities may be supported by
non-governmental credit enhancements similar to those utilized in connection
with mortgage-backed securities. The credit quality of most asset-backed
securities depends primarily on the credit quality of the assets underlying such
securities, how well the entity issuing the security is insulated from the
credit risk of the originator any other affiliated entities, and the amount and
quality of any credit enhancement of the securities.

The yield characteristics of mortgage- and asset-backed securities differ from
those of traditional debt obligations. Among the principal differences are that
interest and principal payments are made more frequently on mortgage- and
asset-backed securities, usually monthly, and that principal may be prepaid at
any time because the underlying mortgage loans or other assets generally may be
prepaid at any time. As a 


                                       7


<PAGE>   69


result, if the Fund purchases these securities at a premium, a prepayment rate
that is faster than expected will reduce yield to maturity, while a prepayment
rate that is lower than expected will have the opposite effect of increasing the
yield to maturity. Conversely, if the Fund purchases these securities at a
discount, a prepayment rate that is faster than expected will increase yield to
maturity, while a prepayment rate that is slower than expected will reduce yield
to maturity. Accelerated prepayments on securities purchased by the Fund at a
premium also impose a risk of loss of principal because the premium may not have
been fully amortized at the time the principal is prepaid in full. The market
for privately issued mortgage- and asset-backed securities is smaller and less
liquid than the market for government sponsored mortgage-backed securities.

The Fund may invest in stripped mortgage- or asset-backed securities, which
receive differing proportions of the interest and principal payments from the
underlying assets. The market value of such securities generally is more
sensitive to changes in prepayment and interest rates than is the case with
traditional mortgage- and asset-backed securities, and in some cases the market
value may be extremely volatile. With respect to certain stripped securities,
such as interest-only ("IO") and principal-only ("PO") classes, a rate of
prepayment that is faster or slower than anticipated may result in the Fund
failing to recover all or a portion of its investment, even though the
securities are rated investment grade.

   
REPURCHASE AGREEMENTS. In connection with the purchase of a repurchase agreement
by the Income Fund, the Fund's custodian will have custody of, and will hold in
a segregated account, securities acquired by the Fund under a repurchase
agreement. Repurchase agreements are contracts under which the buyer of a
security simultaneously commits to resell the security to the seller at an
agreed-upon price and date. Repurchase agreements are considered by the staff of
the Securities and Exchange Commission (the "SEC") to be loans by the Fund.
Repurchase agreements may be entered into with respect to securities of the type
in which it may invest or government securities regardless of their remaining
maturities, and will require that additional securities be deposited with it if
the value of the securities purchased should decrease below the resale price.
Repurchase agreements involve certain risks in the event of default or
insolvency by the other party, including possible delays or restrictions upon
the Fund's ability to dispose of the underlying securities, the risk of a
possible decline in the value of the underlying securities during the period in
which the Fund seeks to assert its rights to them, the risk of incurring
expenses associated with asserting those rights and the risk of losing all or
part of the income from the repurchase agreement.
    

WHEN-ISSUED SECURITIES AND DELAYED-DELIVERY TRANSACTIONS. The Income Fund may
invest without limitation in securities purchased on a "when-issued" basis or
purchase or sell securities for delayed delivery (i.e., payment or delivery
occurs beyond the normal settlement date at a stated price and yield).
When-issued transactions normally settle within 45 days. The payment obligation
and the interest rate that will be received on when-issued securities are fixed
at the time the buyer enters into the commitment. Due to fluctuations in the
value of securities purchased or sold on a when-issued or delayed-delivery
basis, the yields obtained on such securities may be higher or lower than the
yields available in the market on the dates when the investments are actually
delivered to the buyers.

   
When the Fund agrees to purchase when-issued or delayed-delivery securities, its
custodian will set aside cash, or liquid securities equal to the amount of the 
    


                                       8


<PAGE>   70


commitment in a segregated account. Normally, the custodian will set aside
portfolio securities to satisfy a purchase commitment, and in such a case the
Fund may be required subsequently to place additional assets in the segregated
account in order to ensure that the value of the account remains equal to the
amount of such fund's commitment. It may be expected that the Fund's net assets
will fluctuate to a greater degree when it sets aside portfolio securities to
cover such purchase commitments than when it sets aside cash. When the Fund
engages in when-issued or delayed-delivery transactions, it relies on the other
party to consummate the trade. Failure of the seller to do so may result in a
fund incurring a loss or missing an opportunity to obtain a price considered to
be advantageous.

LENDING PORTFOLIO SECURITIES. The Income Fund may lend its portfolio securities
to brokers, dealers and other financial institutions, provided it receives cash
collateral which at all times is maintained in an amount equal to at least 100%
of the current market value of the securities loaned. By lending its portfolio
securities, the Fund can increase its income through the investment of the cash
collateral. For the purposes of this policy, the Fund considers collateral
consisting of cash, U.S. Government securities or letters of credit issued by
banks whose securities meet the standards for investment by the Fund to be the
equivalent of cash. From time to time, the Fund may return to the borrower or a
third party which is unaffiliated with it, and which is acting as a "placing
broker," a part of the interest earned from the investment of collateral
received for securities loaned.

The SEC currently requires that the following conditions must be met whenever
portfolio securities are loaned: (1) the fund must receive at least 100% cash
collateral of the type discussed in the preceding paragraph from the borrower;
(2) the borrower must increase such collateral whenever the market value of the
securities loaned rises above the level of such collateral; (3) the fund must be
able to terminate the loan at any time; (4) the fund must receive reasonable
interest on the loan, as well as any dividends, interest or other distributions
payable on the loaned securities, and any increase in market value; (5) the fund
may pay only reasonable custodian fees in connection with the loan; and (6)
while any voting rights on the loaned securities may pass to the borrower, the
fund's board of directors or trustees must be able to terminate the loan and
regain the right to vote the securities if a material event adversely affecting
the investment occurs. These conditions may be subject to future modification.
Loan agreements involve certain risks in the event of default or insolvency of
the other party including possible delays or restrictions upon the Fund's
ability to recover the loaned securities or dispose of the collateral for the
loan.

BORROWING. The Income Fund may borrow money from banks, limited by any
investment restrictions to 33 1/3% of its total assets. However, the Fund
currently intends to borrow money only for temporary or emergency purposes in an
amount of up to 5% of the value of the Fund's total asset (including the amount
borrowed) valued at the time the borrowing is made. In such situations, either
the custodian will segregate the pledged assets for the benefit of the lender or
arrangements will be made with a suitable subcustodian, which may include the
lender.

SMALL COMPANY FUND

         The Small Company Fund seeks long-term growth of capital. It seeks to
achieve this objective by investing primarily in equity securities of both
domestic and foreign small market capitalization companies ("small company
stocks"). To attempt to achieve this objective, the Adviser has hired a number
of 


                                       9


<PAGE>   71


subadvisers to direct the day-to-day management of the Small Company Fund. The
following information supplements the discussion of the Fund's objectives,
policies and techniques that are described in the Fund's prospectus under
"INVESTMENT OBJECTIVES AND POLICIES" and "INVESTMENT TECHNIQUES, CONSIDERATIONS
AND RISK FACTORS."

         Special Situation Companies. The Small Company Fund may invest in the
securities of "special situation companies," which include those involved in an
actual or prospective acquisition or consolidation; reorganization;
recapitalization; merger, liquidation or distribution of cash, securities or
other assets; a tender or exchange offer; a breakup or workout of a holding
company; or litigation which, if resolved favorably, would improve the value of
the company's stock. If the actual or prospective situation does not materialize
as anticipated, the market price of the securities of a "special situation
company" may decline significantly. The Fund believes, however, that if a
Subadviser analyzes "special situation companies" carefully and invests in the
securities of these companies at the appropriate time, the Fund may achieve
capital growth. There can be no assurance however, that a special situation that
exists at the time the Fund makes its investment will be consummated under the
terms and within the time period contemplated.

         Foreign Securities. Investors in the Small Company Fund should
recognize that investing in foreign securities involves certain special
considerations which are not typically associated with investing in United
States securities. Since investments in foreign companies will frequently
involve currencies of foreign countries, and since the Fund may hold securities
and funds in foreign currencies, the Fund may be affected favorably or
unfavorably by changes in currency rates and in exchange control regulations, if
any, and may incur costs in connection with conversions between various
currencies. Most foreign stock markets, while growing in volume of trading
activity, have less volume than the New York Stock Exchange, and securities of
some foreign companies are less liquid and more volatile than securities of
comparable domestic companies. Similarly, volume and liquidity in most foreign
bond markets are less than in the United States and at times, volatility of
price can be greater than in the United States. Fixed commissions on foreign
securities exchanges are generally higher than negotiated commissions on United
States exchanges, although the Fund endeavors to achieve the most favorable net
results on their portfolio transactions. There is generally less government
supervision and regulation of securities exchanges, brokers and listed companies
in foreign countries than in the United States. In addition, with respect to
certain foreign countries, there is the possibility of exchange control
restrictions, expropriation or confiscatory taxation, and political, economic or
social instability, which could affect investments in those countries. Foreign
securities such as those purchased by the Fund may be subject to foreign
government taxes, higher custodian fees and dividend collection fees which could
reduce the yield on such securities.

         Investments may be made from time to time by the Small Company Fund in
companies in developing countries as well as in developed countries. Although
there is no universally accepted definition, a developing country is generally
considered to be a country which is in the initial stages of industrialization.
Shareholders should be aware that investing in the equity and fixed income
markets of developing countries involves exposure to unstable governments,
economies based on only a few industries, and securities markets which trade a
small number of securities. Securities markets of developing countries tend to
be more volatile than the markets of developed countries; however, such markets
have in the past provided the opportunity for higher rates of return to
investors.

         The value and liquidity of investments in developing countries may be
affected favorably or unfavorably by political, economic, fiscal, regulatory or
other developments in the particular countries or neighboring regions. The
extent of economic development, political stability and market depth of
different countries varies widely. Certain countries in the Asia region,
including Cambodia, China, Laos, Indonesia, Malaysia, the Philippines, Thailand,
and Vietnam are either comparatively underdeveloped or are in the process of
becoming developed. Such investments typically involve greater potential for
gain or loss than investments in securities of issuers in developed countries.


                                       10

         The securities markets in developing countries are substantially
smaller, less liquid and more volatile than the major securities markets in the
United States. A high proportion of the shares of many issuers may be held by a
limited number of persons and financial institutions, which may limit the number
of shares available for investment by the fund. Similarly, volume and liquidity
in the bond markets in developing countries are less than in the United States
and, at times, price volatility can be greater than in the United States. A
limited number of issuers in developing countries' securities markets may
represent a disproportionately large percentage of market capitalization and
trading volume. The limited liquidity of securities markets in developing
countries may also affect the Fund's ability to acquire or dispose of securities
at the price and time it wishes to do so. Accordingly, during periods of rising
securities prices in the more illiquid securities markets, the Fund's ability to
participate fully in such price increases may be limited by its investment
policy of investing not more than 15% of its total net assets in illiquid
securities. Conversely, the Fund's inability to dispose fully and promptly of
positions in declining markets will cause the Fund's net asset value to decline
as the value of the unsold positions is marked to lower prices. In addition,
securities markets in developing countries are susceptible to being influenced
by large investors trading significant blocks of securities.

         Political and economic structures in many of such countries may be
undergoing significant evolution and rapid development, and such countries may
lack the social, political and economic stability characteristic of the United
States. Certain of such countries have in the past failed to recognize private
property rights and have at times nationalized or expropriated the assets of
private companies. As a result, the risks described above, including the risks
of nationalization or expropriation of assets, may be heightened. In addition,
unanticipated political or social developments may affect the value of the
Fund's investments in those countries and the availability to the fund of
additional investments in those countries.

         Economies of developing countries may differ favorably or unfavorably
from the United States economy in such respects as rate of growth of gross
national product, rate of inflation, capital reinvestment, resource
self-sufficiency and balance of payments position. As export-driven economies,
the economies of countries in the Asia Region are affected by developments in
the economies of their principal trading partners. Hong Kong, Japan and Taiwan
have limited natural resources, resulting in dependence on foreign sources for
certain raw materials and economic vulnerability to global fluctuations of price
and supply.

         Certain developing countries do not have comprehensive systems of laws,
although substantial changes have occurred in many such countries in this regard
in recent years. Laws regarding fiduciary duties of officers and directors and
the protection of shareholders may not be well developed. Even where adequate
law exists in such developing countries, it may be impossible to obtain swift
and equitable enforcement of such law, or to obtain enforcement of the judgment
by a court of another jurisdiction.

         Trading in futures contracts traded on foreign commodity exchanges may
be subject to the same or similar risks as trading in foreign securities.

         Depositary Receipts. As indicated in the Fund's prospectus, the Small
Company Fund may invest in foreign securities by purchasing depositary receipts,
including American Depositary Receipts ("ADRs") and European Depositary Receipts
("EDRs") or other securities convertible into securities of issuers based in
foreign countries. These securities may not necessarily be denominated in the
same currency as the securities into which they may be converted. Generally,
ADRs, in registered form, are denominated in U.S. dollars and are designed for
use in the U.S. securities markets, while EDRs (also referred to as Continental
Depositary Receipts ("CDRs"), in bearer form, may be denominated in other
currencies and are designed for use in European securities markets. ADRs are
receipts typically issued by a U.S. Bank or trust company evidencing ownership
of the underlying securities. EDRs are European receipts evidencing a similar
arrangement. For purposes of the Fund's investment policies, ADRs and EDRs are
deemed to have the same classification as the underlying securities they
represent. Thus, an ADR or EDR representing 


                                       11


<PAGE>   73


ownership of common stock will be treated as common stock. (For further
information on these instruments, see the descriptions above for the Government
Bond Fund and the Money Market Fund.)

         The Small Company Fund may invest in depositary receipts through
"sponsored" or "unsponsored" facilities. A sponsored facility is established
jointly by the issuer of the underlying security and a depositary, whereas a
depositary may establish an unsponsored facility without participation by the
issuer of the deposited security. Holders of unsponsored depositary receipts
generally bear all the costs of such facilities and the depositary of an
unsponsored facility frequently is under no obligation to distribute shareholder
communications received from the issuer of the deposited security or to pass
through voting rights to the holders of such receipts in respect of the
deposited securities.

   
         Debt Obligations. While the emphasis of the Small Company Fund's
investment is on common stocks and other equity securities (including preferred
stocks and securities convertible into or exchangeable for common stocks), it
may also invest in money market instruments, U.S. Government or Agency
securities, (for further information concerning these securities, see the
descriptions above for the Government Bond and the Money Market Funds) and
corporate bonds and debentures receiving one of the four highest ratings from an
NRSRO, or if not rated by any NRSRO, deemed comparable by a Subadviser to such
rated securities ("Comparable Unrated Securities"). The ratings of an NRSRO
represent its opinion as to the quality of securities it undertakes to rate.
Ratings are not absolute standards of quality; consequently, securities with the
same maturity, coupon, and rating may have different yields. The ratings
assigned by the NRSROS are described in Appendix A to this Statement of
Additional Information.

         Fixed income securities are subject to the credit risk and market risk
as described above. Lower-rated securities are more likely to react to
developments affecting market and credit risk than are more highly rated
securities, which react primarily to movements in the general level of interest
rates. Subsequent to its purchase by the Fund, an issue of securities may cease
to be rated or its rating may be reduced, so that the securities would not be
eligible for purchase by the Fund. In such a case, the Subadviser will evaluate
whether the downgraded security should be disposed of. 
    

         High-Yield (High-Risk) Securities -- In General. The Fund has the
authority to invest up to 5% of its net assets in non-investment grade debt
securities. Non-investment grade debt securities (hereinafter referred to as
"lower-quality securities") include (i) bonds rated as low as C by Moody's,
Standard & Poor's, or Fitch, or CCC by D&P; (ii) commercial paper rated as low
as C by Standard & Poor's, Not Prime by Moody's or Fitch 4 by Fitch; and (iii)
unrated debt securities of comparable quality. Lower-quality securities, while
generally offering higher yields than investment grade securities with similar
maturities, involve greater risks, including the possibility of default or
bankruptcy. They are regarded as predominantly speculative with respect to the
issuer's capacity to pay interest and repay principal. The special risk
considerations in connection with investments in these securities are discussed
below. Refer to Appendix A of this Statement of Additional Information for a
discussion of securities ratings.

         Effect of Interest Rates And Economic Changes. All interest-bearing
securities typically experience appreciation when interest rates decline and
depreciation when interest rates rise. The market values of lower-quality and
comparable unrated securities tend to reflect individual corporate developments
to a greater extent than do higher rated securities, which react primarily to
fluctuations in the general level of interest rates. Lower-quality and
comparable unrated securities also tend to be more sensitive to economic
conditions than are higher-rated securities. As a result, they generally involve
more credit risks than securities in the higher-rated categories. During an
economic downturn or a sustained period of rising interest rates, highly
leveraged issuers of lower-quality and comparable unrated securities may
experience financial stress and may not have sufficient revenues to meet their
payment obligations. The issuer's ability 


                                       12


<PAGE>   74


to service its debt obligations may also be adversely affected by specific
corporate developments, the issuer's inability to meet specific projected
business forecasts or the unavailability of additional financing. The risk of
loss due to default by an issuer of these securities is significantly greater
than issuers of higher-rated securities because such securities are generally
unsecured and are often subordinated to other creditors. Further, if the issuer
of a lower-quality or comparable unrated security defaulted, the Fund might
incur additional expenses to seek recovery. Periods of economic uncertainty and
changes would also generally result in increased volatility in the market prices
of these securities and thus in the Fund's net asset value.

         As previously stated, the value of a lower-quality or comparable
unrated security will decrease in a rising interest rate market, and accordingly
so will the Fund's net asset value. If the Fund experiences unexpected net
redemptions in such a market, it may be forced to liquidate a portion of its
portfolio securities without regard to their investment merits. Due to the
limited liquidity of lower-quality and comparable unrated securities (discussed
below), the Fund may be forced to liquidate these securities at a substantial
discount. Any such liquidation would reduce the Fund's asset base over which
expenses could be allocated and could result in a reduced rate of return for the
Fund.

         Payment Expectations. Lower-quality and comparable unrated securities
typically contain redemption, call or prepayment provisions which permit the
issuer of such securities containing such provisions to, at its discretion,
redeem the securities. During periods of falling interest rates, issuers of
these securities are likely to redeem or prepay the securities and refinance
them with debt securities at a lower interest rate. To the extent an issuer is
able to refinance the securities, or otherwise redeem them, the Fund may have to
replace the securities with a lower yielding security, which would result in a
lower return for the Fund.

         Credit Ratings. Credit ratings issued by credit-rating agencies
evaluate the safety of principal and interest payments of rated securities. They
do not, however, evaluate the market value risk of lower-quality securities and,
therefore, may not fully reflect the true risks of an investment. In addition,
credit rating agencies may or may not make timely changes in a rating to reflect
changes in the economy or in the condition of the issuer that affect the market
value of the security. Consequently, credit ratings are used only as a
preliminary indicator of investment quality. Investments in lower-quality and
comparable unrated securities will be more dependent on a Subadviser's credit
analysis than would be the case with investments in investment-grade debt
securities. Each Subadviser will employ its own credit research and analysis,
which includes a study of existing debt, capital structure, ability to service
debt and to pay dividends, the issuer's sensitivity to economic conditions, its
operating history and the current trend of earnings. When investing in
lower-quality securities, each Subadviser will continually monitor the
investments in the Fund's portfolio and carefully evaluate whether to dispose of
or to retain lower-quality and comparable unrated securities whose credit
ratings or credit quality may have changed.

         Liquidity And Valuation. The Fund may have difficulty disposing of
certain lower-quality and comparable unrated securities because there may be a
thin trading market for such securities. Because not all dealers maintain
markets in all lower-quality and comparable unrated securities, there is no
established retail secondary market for many of these securities. The Fund
anticipates that such securities could be sold only to a limited number of
dealers or institutional investors. To the extent a secondary trading market
does exist, it is generally not as liquid as the secondary market for
higher-rated securities. The lack of a liquid secondary market may have an
adverse impact on the market price of the security. As a result, the Fund's
asset value and ability to dispose of particular securities, when necessary to
meet the Fund's liquidity needs or in response to a specific economic event, may
be impacted. The lack of a liquid secondary market for certain securities may
also make it more difficult for the Fund to obtain accurate market quotations
for purposes of valuing the Fund's portfolio. Market quotations are generally
available on many lower-quality and comparable unrated issues only from a
limited number of dealers and may not necessarily represent firm bids of such
dealers or prices for actual sales. During periods of thin trading, the 


                                       13


<PAGE>   75


spread between bid and asked prices is likely to increase significantly. In
addition, adverse publicity and investor perceptions, whether or not based on
fundamental analysis, may decrease the values and liquidity of lower-quality and
comparable unrated securities, especially in a thinly traded market.


         Proposed Legislation. From time to time proposals have been discussed,
regarding new legislation designed to limit the use of certain lower-quality and
comparable unrated securities by certain issuers. However, it is possible that
if legislation is enacted or proposed, it could have a material affect on the
value of these securities and the existence of a secondary trading market for
the securities.

         Convertible Securities. Convertible securities in which the Fund may
invest, including both convertible debt and convertible preferred stock, may be
converted at either a stated price or stated rate into underlying shares of
common stock. Because of this feature, convertible securities enable an investor
to benefit from increases in the market price of the underlying common stock.
Convertible securities provide higher yields than the underlying equity
securities, but generally offer lower yields than non-convertible securities of
similar quality. Like bonds, the value of convertible securities fluctuates in
relation to changes in interest rates and, in addition, also fluctuates in
relation to the underlying common stock.

         Warrants. The Small Company Fund may acquire warrants. Warrants are
securities giving the holder the right, but not the obligation, to buy the stock
of an issuer at a given price (generally higher than the value of the stock at
the time of issuance), on a specified date, during a specified period, or
perpetually. Warrants may be acquired separately or in connection with the
acquisition of securities. The Fund may purchase warrants, valued at the lower
of cost or market value, of up to 5% of the Fund's net assets. Included in that
amount, but not to exceed 2% of the Fund's net assets, may be warrants that are
not listed on any recognized U.S. or foreign stock exchange. Warrants acquired
by the Fund in units or attached to securities are not subject to these
restrictions. Warrants do not carry with them the right to dividends or voting
rights with respect to the securities that they entitle their holder to
purchase, and they do not represent any rights in the assets of the issuer. As a
result, warrants may be considered more speculative than certain other types of
investments. In addition, the value of a warrant does not necessarily change
with the value of the underlying securities, and a warrant ceases to have value
if it is not exercised prior to its expiration date.

   
         Repurchase Agreements. The Small Company Fund's custodian or a
sub-custodian will have custody of, and will hold in a segregated account,
securities acquired by the Fund under a repurchase agreement. Repurchase
agreements are contracts under which the buyer of a security simultaneously
commits to resell the security to the seller at an agreed-upon price and date.
Repurchase agreements are considered by the staff of the Securities and Exchange
Commission to be loans by the Fund. In an attempt to reduce the risk of
incurring a loss on the repurchase agreement, the Fund will enter into
repurchase agreements with certain banks and non-bank dealers, all of whose use
has been approved by the Board of Trustees. Repurchase agreements may be entered
into with respect to securities of the type in which it may invest or government
securities regardless of their remaining maturities, and will require that
additional securities be deposited with it if the value of the securities
purchased should decrease below resale price. Each Subadviser will monitor on an
ongoing basis the value of the collateral to assure that it always equals or
exceeds the repurchase price. The Fund will consider on an ongoing basis the
creditworthiness of the institutions with which the Fund enters into repurchase
agreements. Repurchase agreements involve certain risks in the event of default
or insolvency by the other party, including possible delays or restrictions upon
the Fund's ability to dispose of the underlying securities.

         Short Sales "Against The Box". In a short sale, the Small Company Fund
sells a borrowed security and has a corresponding obligation to the lender to
replace such security. The Fund may engage in short sales if at the time of the
short sale the Fund owns or has the right to obtain without additional cost an 
    

                                       14


<PAGE>   76


equal amount of the security being sold short. This investment technique is
known as a short sale "against the box."

   
         In a short sale, the seller does not immediately deliver the securities
sold and is said to have a short position in those securities until delivery
occurs. If the Fund engages in a short sale, the collateral for the short
position will be maintained by the Fund's custodian or qualified sub-custodian.
While the short sale against the box is open, the Fund will maintain in a
segregated account an amount of securities equal in kind and amount to the
securities sold short or securities convertible into or exchangeable for such
equivalent securities. These securities constitute the Fund's long position. Not
more than 15% of the Fund's net assets (taken at current value) may be held as
collateral for such short sales at any one time.
    
   
         The Fund does not intend to engage in short sales against the box for
investment purposes. The Fund may, however, make a short sale as a hedge, when
it believes that the price of a security may decline, causing a decline in the
value of a security owned by the Fund (or a security convertible or exchangeable
for such security). In such case, any future losses in the Fund's long position
should be offset by a gain in the short position and, conversely, any gain in
the long position should be reduced by a loss in the short position. The extent
to which such gains or losses are reduced will depend upon the amount of the
security sold short relative to the amount the Fund owns. There will be certain
additional transaction costs associated with short sales against the box, but
the Fund will endeavor to offset these costs with the income from the investment
of the cash proceeds of short sales.
    

         Restricted, Non-Publicly Traded and Illiquid Securities. The Small
Company Fund may not invest more than 15% of its net assets, in the aggregate,
in illiquid securities, including repurchase agreements which have a maturity of
longer than seven days, time deposits maturing in more than seven days and
securities that are illiquid because of the absence of a readily available
market or legal or contractual restrictions on resale. Repurchase agreements
subject to demand are deemed to have a maturity equal to the notice period.

   
         Historically, illiquid securities have included securities subject to
contractual or legal restrictions on resale because they have not been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
securities which are otherwise not readily marketable and repurchase agreements
having a maturity of longer than seven days. Securities which have not been
registered under the Securities Act are referred to as private placements or
restricted securities and are purchased directly from the issuer or in the
secondary market. Investment companies do not typically hold a significant
amount of these restricted or other illiquid securities because of the potential
for delays on resale and uncertainty in valuation. Limitations on resale may
have an adverse effect on the marketability of portfolio securities, and an
investment company might be unable to dispose of restricted or other illiquid
securities promptly or at reasonable prices and might thereby experience
difficulty satisfying redemptions within seven days. An investment company might
also have to register such restricted securities in order to dispose of them
resulting in additional expense and delay. Adverse market conditions could
impede such a public offering of securities.
    

         In recent years, however, a large institutional market has developed
for certain securities that are not registered under the Securities Act
including repurchase agreements, commercial paper, foreign securities, municipal
securities and corporate bonds and notes. Institutional investors depend on an
efficient institutional market in which the unregistered security can be readily
resold or on an issuer's ability to honor a demand for repayment. The fact that
there are contractual or legal restrictions on resale to the general public or
to certain institutions may not be indicative of the liquidity of such
investments.


                                       15


<PAGE>   77


         The SEC has adopted Rule 144A which allows for a broader institutional
trading market for securities otherwise subject to restriction on resale to the
general public. Rule 144A establishes a "safe harbor" from the registration
requirements of the securities act for resales of certain securities to
qualified institutional buyers. It is anticipated that the market for certain
restricted securities such as institutional commercial paper will expand further
as a result of this regulation and use of automated systems for the trading,
clearance and settlement of unregistered securities of domestic and foreign
issuers, such as the PORTAL System sponsored by the National Association of
Securities Dealers, Inc.

         The Fund may sell over-the-counter ("OTC") options and, in connection
therewith, segregate assets or cover its obligations with respect to OTC options
written by the Fund. The assets used as cover for OTC options written by the
Fund will be considered illiquid unless the OTC options are sold to qualified
dealers who agree that the Fund may repurchase any OTC option it writes at a
maximum price to be calculated by a formula set forth in the option agreement.
The cover for an OTC option written subject to this procedure would be
considered illiquid only to the extent that the maximum repurchase price under
the formula exceeds the intrinsic value of the option.

   
         Each Subadviser will monitor the liquidity of restricted securities in
the portion of the Fund it manages under the supervision of the Board of
Trustees and the Adviser. In reaching liquidity decisions, each Subadviser may
consider the following factors: (A) the unregistered nature of the security; (B)
the frequency of trades and quotes for the security; (C) the number of dealers
wishing to purchase or sell the security and the number of other potential
purchasers; (D) dealer undertakings to make a market in the security and (E) the
nature of the security and the nature of the marketplace trades (e.g., the time
needed to dispose of the security, the method of soliciting offers and the
mechanics of the transfer).
    

         When-Issued Securities And Delayed-Delivery Transactions. The Small
Company Fund may invest without limitation in securities purchased on a
"when-issued" basis or purchase or sell securities for delayed delivery (i.e.,
payment or delivery occurs beyond the normal settlement date at a stated price
and yield). When-issued transactions normally settle within 45 days. The Fund
will enter into a when-issued transaction for the purpose of acquiring portfolio
securities and not for the purpose of leverage, but may sell the securities
before the settlement date if a Subadviser which purchased such security deems
it advantageous to do so. The payment obligation and the interest rate that will
be received on when-issued securities are fixed at the time the buyer enters
into the commitment. Due to fluctuations in the value of securities purchased or
sold on a when-issued or delayed-delivery basis, the yields obtained on such
securities may be higher or lower than the yields available in the market on the
dates when the investments are actually delivered to the buyers.

         When the Fund agrees to purchase when-issued or delayed-delivery
securities, its custodian will set aside cash, U.S. government securities or
other liquid high-grade debt obligations equal to the amount of the commitment
in a segregated account. Normally, the custodian will set aside portfolio
securities to satisfy a purchase commitment, and in such a case the Fund may be
required subsequently to place additional assets in the segregated account in
order to ensure that the value of the account remains equal to the amount of the
Fund's commitment. It may be expected that the Fund's net assets will fluctuate
to a greater degree when it sets aside portfolio securities to cover such
purchase commitments than when it sets aside cash. When the Fund engages in
when-issued or delayed-delivery transactions, it relies on the other party to
consummate the trade. Failure of the seller to do so may result in the Fund
incurring a loss or missing an opportunity to obtain a price considered to be
advantageous.

         Lending Portfolio Securities. The Small Company Fund may lend its
portfolio securities to brokers, dealers and other financial institutions,
provided it receives cash collateral which at all times is maintained in an
amount equal to at least 100% of the current market value of the securities
loaned. By lending its portfolio securities, the Fund can increase its income
through the investment of the cash collateral. For the purposes of this policy,
the Fund considers collateral consisting of cash, U.S. 


                                       16


<PAGE>   78


Government securities or letters of credit issued by banks whose securities meet
the standards for investment by the Fund to be the equivalent of cash. From time
to time, the Fund may return to the borrower or a third party which is
unaffiliated with the Fund, and which is acting as a "placing broker," a part of
the interest earned from the investment of collateral received for securities
loaned. The SEC currently requires that the following conditions must be met
whenever portfolio securities are loaned: (1) the Fund must receive at least
100% cash collateral of the type discussed in the preceding paragraph from the
borrower; (2) the borrower must increase such collateral whenever the market
value of the securities loaned rises above the level of such collateral; (3) the
Fund must be able to terminate the loan at any time; (4) the Fund must receive
reasonable interest on the loan, as well as any dividends, interest or other
distributions payable on the loaned securities, and any increase in market
value; (5) the Fund may pay only reasonable custodian fees in connection with
the loan; and (6) while any voting rights on the loaned securities may pass to
the borrower, the Trust's Trustees must be able to terminate the loan and regain
the right to vote the securities if a material event adversely affecting the
investment occurs. These conditions may be subject to future modification. Loan
agreements involve certain risks in the event of default or insolvency of the
other party including possible delays or restrictions upon the Fund's ability to
recover the loaned securities or dispose of the collateral for the loan.

         Borrowing. The Small Company Fund may borrow money from banks, limited
by the Fund's fundamental investment restriction to 33-1/3% of its total assets,
and may engage in reverse repurchase agreements which may be considered a form
of borrowing. (See "INVESTMENT TECHNIQUES, CONSIDERATIONS AND RISK FACTORS -
Reverse Repurchase Agreements" in the Small Company Fund's Prospectus.) In
addition, the Fund may borrow up to an additional 5% of its total assets from
banks for temporary or emergency purposes. The Fund will not purchase securities
when bank borrowings exceed 5% of the Fund's total assets. The Fund expects that
some of its borrowings may be on a secured basis. In such situations, either the
custodian will segregate the pledged assets for the benefit of the lender or
arrangements will be made with a suitable subcustodian, which may include the
lender.

         Derivative Instruments. As discussed in its Prospectus, each of the
Small Company Fund's Subadvisers may use a variety of derivative instruments,
including options, futures contracts (sometimes referred to as "futures"),
options on futures contracts, stock index options and forward currency contracts
to hedge the Fund's portfolio or for risk management.

         The use of these instruments is subject to applicable regulations of
the SEC, the several options and futures exchanges upon which they may be
traded, the Commodity Futures Trading Commission ("CFTC") and various state
regulatory authorities. In addition, the Fund's ability to use these instruments
will be limited by tax considerations.

         Special Risks Of Derivative Instruments. The use of derivative
instruments involves special considerations and risks as described below. Risks
pertaining to particular instruments are described in the sections that follow.

         (1) Successful use of most of these instruments depends upon a
Subadviser's ability to predict movements of the overall securities and currency
markets, which requires different skills than predicting changes in the prices
of individual securities. While each Subadviser is experienced in the use of
these instruments, there can be no assurance that any particular strategy
adopted will succeed.

         (2) There might be imperfect correlation, or even no correlation,
between price movements of an instrument and price movements of investments
being hedged. For example, if the value of an instrument used in a short hedge
(such as writing a call option, buying a put option, or selling a futures
contract) increased by less than the decline in value of the hedged investment,
the hedge would not be fully successful. Such a lack of correlation might occur
due to factors unrelated to the value of the investments being hedged, such as
speculative or other pressures on the markets in which these instruments are
traded. 


                                       17


<PAGE>   79


The effectiveness of hedges using instruments on indices will depend on the
degree of correlation between price movements in the index and price movements
in the investments being hedged.

         (3) Hedging strategies, if successful, can reduce the risk of loss by
wholly or partially offsetting the negative effect of unfavorable price
movements in the investments being hedged. However, hedging strategies can also
reduce opportunity for gain by offsetting the positive effect of favorable price
movements in the hedged investments. For example, if the Fund entered into a
short hedge because a Subadviser projected a decline in the price of a security
in the Fund's portfolio, and the price of that security increased instead, the
gain from that increase might be wholly or partially offset by a decline in the
price of the instrument. Moreover, if the price of the instrument declined by
more than the increase in the price of the security, the Fund could suffer a
loss.

         (4) As described below, the Fund might be required to maintain assets
as "cover," maintain segregated accounts, or make margin payments when it takes
positions in these instruments involving obligations to third parties (i.e.,
instruments other than purchased options). If the Fund were unable to close out
its positions in such instruments, it might be required to continue to maintain
such assets or accounts or make such payments until the position expired or
matured. The requirements might impair the Fund's ability to sell a portfolio
security or make an investment at a time when it would otherwise be favorable to
do so, or require that the Fund sell a portfolio security at a disadvantageous
time. The Fund's ability to close out a position in an instrument prior to
expiration or maturity depends on the existence of a liquid secondary market or,
in the absence of such a market, the ability and willingness of the other party
to the transaction ("counter party") to enter into a transaction closing out the
position. Therefore, there is no assurance that any hedging position can be
closed out at a time and price that is favorable to the Fund.

         For a discussion of the federal income tax treatment of the Fund's
derivative instruments, see "Tax Status" below.

         Options. The Small Company Fund may purchase or write put and call
options on securities and indices, and may purchase options on foreign currency,
and enter into closing transactions with respect to such options to terminate an
existing position. The purchase of call options serves as a long hedge, and the
purchase of put options serves as a short hedge. Writing put or call options can
enable the Fund to enhance income by reason of the premiums paid by the
purchaser of such options. Writing call options serves as a limited short hedge
because declines in the value of the hedged investment would be offset to the
extent of the premium received for writing the option. However, if the security
appreciates to a price higher than the exercise price of the call option, it can
be expected that the option will be exercised, and the Fund will be obligated to
sell the security at less than its market value or will be obligated to purchase
the security at a price greater than that at which the security must be sold
under the option. All or a portion of any assets used as cover for OTC options
written by a Fund would be considered illiquid to the extent described under
"Restricted and Illiquid Securities" above. Writing put options serves as a
limited long hedge because increases in the value of the hedged investment would
be offset to the extent of the premium received for writing the option. However,
if the security depreciates to a price lower than the exercise price of the put
option, it can be expected that the put option will be exercised, and the Fund
will be obligated to purchase the security at more than its market value.

         The value of an option position will reflect, among other things, the
historical price volatility of the underlying investment, the current market
value of the underlying investment, the time remaining until expiration, the
relationship of the exercise price to the market price of the underlying
investment, and general market conditions. Options that expire unexercised have
no value. Options used by the Fund may include European-style options, which are
only exercisable at expiration. This is in contrast to American-style options
which are exercisable at any time prior to the expiration date of the option.

         The Fund may effectively terminate its right or obligation under an
option by entering into a closing transaction. For example, the Fund may
terminate its obligation under a call or put option that it had written by
purchasing an identical call or put option; this is known as a closing purchase
transaction. Conversely, the Fund may terminate a position in a put or call
option it had purchased by writing an identical put or call option; this is
known as a closing sale transaction. Closing transactions permit the fund to
realize the profit or limit the loss on an option position prior to its exercise
or expiration.

         The Fund may purchase or write both OTC options and options traded on
foreign and U.S. exchanges. Exchange-traded options are issued by a clearing
organization affiliated with the exchange on which the option is listed that, in
effect, guarantees completion of every exchange-traded option transaction. OTC
options are contracts between the fund and the counter party (usually a
securities dealer or a bank) with no clearing organization guarantee. Thus, when
the Fund purchases or writes an OTC option, it relies on the counter party to
make or take delivery of the underlying investment upon exercise of the option.
Failure by the counter party to do so would result in the loss of any premium
paid by the fund as well as the loss of any expected benefit of the transaction.

         The Fund's ability to establish and close out positions in
exchange-listed options depends on the existence of a liquid market. The Fund
intends to purchase or write only those exchange-traded options for which there
appears to be a liquid secondary market. However, there can be no assurance that
such a market will exist at any particular time. Closing transactions can be
made for OTC options only by negotiating directly with the counter party, or by
a transaction in the secondary market if any such market exists. Although the
Fund will enter into OTC options only with counter parties that are expected to
be capable of entering into closing transactions with the fund, there is no
assurance that the Fund will in fact be able to close out an OTC option at a
favorable price prior to expiration. In the event of insolvency of the counter
party, the Fund might be unable to close out an OTC option position at any time
prior to its expiration.

         If the Fund were unable to effect a closing transaction for an option
it had purchased, it would have to exercise the option to realize any profit.
The inability to enter into a closing purchase transaction for a covered call
option written by the Fund could cause material losses because the Fund would be
unable to sell the investment used as a cover for the written option until the
option expires or is exercised.

         The Fund may engage in options transactions on indices in much the same
manner as the options on securities discussed above, except that index options
may serve as a hedge against overall fluctuations in the securities markets in
general.

         The writing and purchasing of options is a highly specialized activity
that involves investment techniques and risks different from those associated
with ordinary portfolio securities transactions. Imperfect correlation between
the options and securities markets may detract from the effectiveness of
attempted hedging.

   
         Transactions using options (other than purchased options) expose the
Fund to counter party risk. To the extent required by sec guidelines, the Fund
will not enter into any such transactions unless it owns either (1) an
offsetting ("covered") position in securities, other options, or futures or (2)
cash and liquid securities with a value sufficient at all times to cover its
potential obligations to the extent not covered as provided in (1) above. The
Fund will also set aside cash and/or appropriate liquid assets in a segregated
custodial account if required to do so by the SEC and CFTC regulations. Assets
used as cover or held in a segregated account cannot be sold while the position
in the corresponding option or futures contract is open, unless they are
replaced with similar assets. As a result, the commitment of a large portion of
the Fund's assets to segregated accounts as a cover could impede portfolio
management or the Fund's ability to meet redemption requests or other current
obligations.

         Spread Transactions. The Small Company Fund may purchase covered spread
options from securities dealers. Such covered spread options are not presently
exchange-listed or exchange-traded. The purchase of a spread option gives the
Fund the right to put, or sell, a security that it owns at a fixed dollar spread
or fixed yield spread in relationship to another security that the Fund does not
own, but which is used as a benchmark. The risk to the Fund in purchasing
covered spread options it the cost of the premium paid for the spread option and
any transaction costs. In addition, there is no assurance that closing
transactions will be available. The purchase of spread options will be used to
protect the Fund against adverse changes in prevailing credit quality spreads,
i.e., the yield spread between high quality and lower quality securities. Such
protection is only provided during the life of the spread option.

         Futures Contracts. The Small Company Fund may enter into futures
contracts, including interest rate, index, and currency futures and purchase and
write (sell) related options. The purchase of futures or call options thereon
can serve as a long hedge, and the sale of futures or the purchase of put
options thereon can serve as a short hedge. Writing covered call options on
futures contracts can serve as a limited short hedge, and writing covered put
options on futures contracts can serve as a limited long hedge, using a strategy
similar to that used for writing covered options in securities. The Fund's
hedging may include purchases of futures as an offset against the effect of
expected increases in securities prices or currency exchange rates and sales of
futures as an offset against the effect of expected declines in securities
prices or currency exchange rates. The Fund may write put options on futures
contracts while at the same time purchasing call options on the same futures
contracts in order to create synthetically a long futures contract position.
Such options would have the same strike prices and expiration dates. The Fund
will engage in this strategy only when a Subadviser believes it is more
advantageous to the Fund than is purchasing the futures contract.

         The Fund will only enter into futures contracts that are traded on U.S.
or foreign exchanges or boards of trade approved by the CFTC and are
standardized as to maturity date and underlying financial instrument. These
transactions may be entered into for "bona fide hedging" purposes as defined in
CFTC regulations and other permissible purposes including increasing return and
hedging against changes in the value of portfolio securities due to anticipated
changes in interest rates, currency values and/or market conditions. The ability
of the Fund to trade in futures contracts may be limited by the requirements of
the code applicable to a regulated investment company.

         The Fund will not enter into futures contracts and related options for
other than "bona fide hedging" purposes for which the aggregate initial margin
and premiums required to establish positions exceed 5% of the Fund's net asset
value after taking into account unrealized profits and unrealized losses on any
such contracts it has entered into. There is no overall limit on the percentage
of the Fund's assets that may be at risk with respect to futures activities.
Although techniques other than sales and purchases of futures contracts could be
used to reduce the Fund's exposure to market, currency, or interest rate
fluctuations, the Fund may be able to hedge its exposure more effectively and
perhaps at a lower cost through using futures contracts.

         A futures contract provides for the future sale by one party and
purchase by another party of a specified amount of a specific financial
instrument (e.g., debt security) or currency for a specified price at a
designated date, time, and place. An index futures contract is an agreement
pursuant to which the parties agree to take or make delivery of an amount of
cash equal to a specified multiplier times the difference between the value of
the index at the close of the last trading day of the contract and the price at
which the index futures contract was originally written. Transactions costs are
incurred when a futures contract is bought or sold and margin deposits must be
maintained. A futures contract may be satisfied by delivery or purchase, as the
case may be, of the instrument, the currency, or by payment of the change in the
cash value of the index. More commonly, futures contracts are closed out prior
to delivery by entering into an offsetting transaction in a matching futures
contract. Although the value of an index might be a function of 


                                       20


<PAGE>   82


the value of certain specified securities, no physical delivery of those
securities is made. If the offsetting purchase price is less than the original
sale price, the Fund realizes a gain; if it is more, the Fund realizes a loss.
Conversely, if the offsetting sale price is more than the original purchase
price, the Fund realizes a gain; if it is less, the Fund realizes a loss. The
transaction costs must also be included in these calculations. There can be no
assurance, however, that the Fund will be able to enter into an offsetting
transaction with respect to a particular futures contract at a particular time.
If the Fund is not able to enter into an offsetting transaction, the Fund will
continue to be required to maintain the margin deposits on the futures contract.

         No price is paid by the Fund upon entering into a futures contract.
Instead, at the inception of a futures contract, the fund is required to deposit
in a segregated account with its custodian, in the name of the futures broker
through whom the transaction was effected, "initial margin" consisting of cash,
U.S. government securities or other liquid, high grade debt obligations, in an
amount generally equal to 10% or less of the contract value. Margin must also be
deposited when writing a call or put option on a futures contract, in accordance
with applicable exchange rules. Unlike margin in securities transactions,
initial margin on futures contracts does not represent a borrowing, but rather
is in the nature of a performance bond or good-faith deposit that is returned to
the Fund at the termination of the transaction if all contractual obligations
have been satisfied. Under certain circumstances, such as periods of high
volatility, the Fund may be required by an exchange to increase the level of its
initial margin payment, and initial margin requirements might be increased
generally in the future by regulatory action.

         Subsequent "variation margin" payments are made to and from the futures
broker daily as the value of the futures position varies, a process known as
"marking to market." Variation margin does not involve borrowing, but rather
represents a daily settlement of a Fund's obligations to or from a futures
broker. When the fund purchases an option on a future, the premium paid plus
transaction costs is all that is at risk. In contrast, when the Fund purchases
or sells a futures contract or writes a call or put option thereon, it is
subject to daily variation margin calls that could be substantial in the event
of adverse price movements. If the Fund has insufficient cash to meet daily
variation margin requirements, it might need to sell securities at a time when
such sales are disadvantageous. Purchasers and sellers of futures positions and
options on futures can enter into offsetting closing transactions by selling or
purchasing, respectively, an instrument identical to the instrument held or
written. Positions in futures and options on futures may be closed only on an
exchange or board of trade on which they were entered into (or through a linked
exchange). Although the Fund intends to enter into futures transactions only on
exchanges or boards of trade where there appears to be an active market, there
can be no assurance that such a market will exist for a particular contract at a
particular time.

         Under certain circumstances, futures exchanges may establish daily
limits on the amount that the price of a future or option on a futures contract
can vary from the previous day's settlement price; once that limit is reached,
no trades may be made that day at a price beyond the limit. Daily price limits
do not limit potential losses because prices could move to the daily limit for
several consecutive days with little or no trading, thereby preventing
liquidation of unfavorable positions.

         If the Fund were unable to liquidate a futures or option on a futures
contract position due to the absence of a liquid secondary market or the
imposition of price limits, it could incur substantial losses. The Fund would
continue to be subject to market risk with respect to the position. In addition,
except in the case of purchased options, the Fund would continue to be required
to make daily variation margin payments and might be required to maintain the
position being hedged by the future or option or to maintain cash or securities
in a segregated account.

         Certain characteristics of the futures market might increase the risk
that movements in the prices of futures contracts or options on futures
contracts might not correlate perfectly with movements in the prices of the
investments being hedged. For example, all participants in the futures and
options on futures contracts markets are subject to daily variation margin calls
and might be compelled to liquidate futures or 


                                       21


<PAGE>   83

options on futures contracts positions whose prices are moving unfavorably to
avoid being subject to further calls. These liquidations could increase price
volatility of the instruments and distort the normal price relationship between
the futures or options and the investments being hedged. Also, because initial
margin deposit requirements in the futures markets are less onerous than margin
requirements in the securities markets, there might be increased participation
by speculators in the future markets. This participation also might cause
temporary price distortions. In addition, activities of large traders in both
the futures and securities markets involving arbitrage, "program trading" and
other investment strategies might result in temporary price distortions.

         Swap Agreements. The Small Company Fund may enter into interest rate,
securities index, commodity, or security and currency exchange rate swap
agreements for any lawful purpose consistent with the Fund's investment
objective, such as for the purpose of attempting to obtain or preserve a
particular desired return or spread at a lower cost to the Fund than if the Fund
had invested directly in an instrument that yielded that desired return or
spread. The Fund also may enter into swaps in order to protect against an
increase in the price of, or the currency exchange rate applicable to,
securities that the Fund anticipates purchasing at a later date. Swap agreements
are two-party contracts entered into primarily by institutional investors for
periods ranging from a few weeks to several years. In a standard "swap"
transaction, two parties agree to exchange the returns (or differentials in
rates of return) earned or realized on particular predetermined investments or
instruments. The gross returns to be exchanged or "swapped" between the parties
are calculated with respect to a "notional amount," i.e., the return on or
increase in value of a particular dollar amount invested at a particular
interest rate, in a particular foreign currency, or in a "basket" of securities
representing a particular index. Swap agreements may include interest rate caps,
under which, in return for a premium, one party agrees to make payments to the
other to the extent that interest rates exceed a specified rate, or "cap";
interest rate floors under which, in return for a premium, one party agrees to
make payments to the other to the extent that interest rates fall below a
specified level, or "floor"; and interest rate collars, under which a party
sells a cap and purchases a floor, or vice versa, in an attempt to protect
itself against interest rate movements exceeding given minimum or maximum
levels.

         The "notional amount" of the swap agreement is the agreed upon basis
for calculating the obligations that the parties to a swap agreement have agreed
to exchange. Under most swap agreements entered into by the Fund, the
obligations of the parties would be exchanged on a "net basis." Consequently,
the Fund's obligation (or rights) under a swap agreement will generally be equal
only to the net amount to be paid or received under the agreement based on the
relative values of the positions held by each party to the agreement (the "net
amount"). The Fund's obligation under a swap agreement will be accrued daily
(offset against amounts owed to the Fund) and any accrued but unpaid net amounts
owed to a swap counterparty will be covered by the maintenance of a segregate
account consisting of cash, or liquid high grade debt obligations.

         Whether the Fund's use of swap agreements will be successful in
furthering its investment objective will depend, in part, on a Subadviser's
ability to predict correctly whether certain types of investments are likely to
produce greater returns than other investments. Swap agreements may be
considered to be illiquid. Moreover, the Fund bears the risk of loss of the
amount expected to be received under a swap agreement in the event of the
default or bankruptcy of a swap agreement counterparty. Certain restrictions
imposed on the Fund by the Internal Revenue Code may limit the Fund's ability to
use swap agreements. The swaps market is largely unregulated.

         The Fund will enter swap agreements only with counterparties that a
Subadviser reasonably believes are capable of performing under the swap
agreements. If there is a default by the other party to such a transaction, the
Fund will have to rely on its contractual remedies (which may be limited by
bankruptcy, insolvency or similar laws) pursuant to the agreements related to
the transaction.

         Foreign Currency-Related Derivative Strategies - Special
Considerations. The Small Company Fund may use options and futures on foreign
currencies and forward currency contracts to hedge against movements in the
values of the foreign currencies in which the Fund's securities are denominated.
The Fund may engage in currency exchange transactions to protect against
uncertainty in the level of future exchange rates and may also engage in
currency transactions to increase income and total return. Such currency hedges
can protect against price movements in a security the Fund owns or intends to
acquire that are attributable to changes in the value of the currency in which
it is denominated. Such hedges do not, however, protect against price movements
in the securities that are attributable to other causes.

         The Fund might seek to hedge against changes in the value of a
particular currency when no hedging instruments on that currency are available
or such hedging instruments are more expensive than certain other hedging
instruments. In such cases, the Fund may hedge against price movements in that
currency by entering into transactions using hedging instruments on another
foreign currency or a basket of currencies, the values of which a subadviser
believes will have a high degree of positive correlation to the value of the
currency being hedged. The risk that movements in the price of the hedging
instrument will not correlate perfectly with movements in the price of the
currency being hedged is magnified when this strategy is used.

         The value of derivative instruments on foreign currencies depends on
the value of the underlying currency relative to the U.S. dollar. Because
foreign currency transactions occurring in the interbank market might involve
substantially larger amounts than those involved in the use of such hedging
instruments, the Fund could be disadvantaged by having to deal in the odd lot
market (generally consisting of transactions of less than $1 million) for the
underlying foreign currencies at prices that are less favorable than for round
lots.

         There is no systematic reporting of last sale information for foreign
currencies or any regulatory requirement that quotations available through
dealers or other market sources be firm or revised on a timely basis. Quotation
information generally is representative of very large transactions in the
interbank market and thus might not reflect odd-lot transactions where rates
might be less favorable. The interbank market in foreign currencies is a global,
round-the-clock market. To the extent the U.S. options or futures markets are
closed while the markets for the underlying currencies remain open, significant
price and rate movements might take place in the underlying markets that cannot
be reflected in the markets for the derivative instruments until they reopen.

         Settlement of derivative transactions involving foreign currencies
might be required to take place within the country issuing the underlying
currency. Thus, the Fund might be required to accept or make delivery of the
underlying foreign currency in accordance with any U.S. or foreign regulations
regarding the maintenance of foreign banking arrangements by U.S. residents and
might be required to pay any fees, taxes and charges associated with such
delivery assessed in the issuing country.

         Permissible foreign currency options will include options traded
primarily in the OTC market. Although options on foreign currencies are traded
primarily in the OTC market, the Fund will normally purchase OTC options on
foreign currency only when a Subadviser believes a liquid secondary market will
exist for a particular option at any specific time.

         Forward Currency Contracts. A forward currency contract involves an
obligation to purchase or sell a specific currency at a future date, which may
be any fixed number of days from the date of the contract agreed upon by the
parties, at a price set at the time of the contract. These contracts are entered
into in the interbank market conducted directly between currency traders
(usually large commercial banks) and their customers.


                                       23


<PAGE>   85


         At or before the maturity of a forward contract, the Small Company Fund
may either sell a portfolio security and make delivery of the currency, or
retain the security and fully or partially offset its contractual obligation to
deliver the currency by purchasing a second contract. If the Fund retains the
portfolio security and engages in an offsetting transaction, the Fund, at the
time of execution of the offsetting transaction, will incur a gain or a loss to
the extent that movement has occurred in forward contract prices.

         The precise matching of forward currency contract amounts and the value
of the securities involved generally will not be possible because the value of
such securities, measured in the foreign currency, will change after the foreign
currency contract has been established. Thus, the Fund might need to purchase or
sell foreign currencies in the spot (cash) market to the extent such foreign
currencies are not covered by forward contracts. The projection of short-term
currency market movements is extremely difficult, and the successful execution
of a short-term hedging strategy is highly uncertain.

         Currency Hedging. While the values of forward currency contracts,
currency options, currency futures and options on futures may be expected to
correlate with exchange rates, they will not reflect other factors that may
affect the value of the Small Company Fund's investments. A currency hedge, for
example, should protect a Yen-denominated bond against a decline in the Yen, but
will not protect the Fund against price decline if the issuer's creditworthiness
deteriorates. Because the value of the Fund's investments denominated in foreign
currency will change in response to many factors other than exchange rates, a
currency hedge may not be entirely successful in mitigating changes in the value
of the Fund's investments denominated in that currency over time.

         A decline in the dollar value of a foreign currency in which the Fund's
securities are denominated will reduce the dollar value of the securities, even
if their value in the foreign currency remains constant. The use of currency
hedges does not eliminate fluctuations in the underlying prices of the
securities, but it does establish a rate of exchange that can be achieved in the
future. In order to protect against such diminutions in the value of securities
it holds, the Fund may purchase put options on the foreign currency. If the
value of the currency does decline, the Fund will have the right to sell the
currency for a fixed amount in dollars and will thereby offset, in whole or in
part, the adverse effect on its securities that otherwise would have resulted.
Conversely, if a rise in the dollar value of a currency in which securities to
be acquired are denominated is projected, thereby potentially increasing the
cost of the securities, the Fund may purchase call options on the particular
currency. The purchase of these options could offset, at least partially, the
effects of the adverse movements in exchange rates. Although currency hedges
limit the risk of loss due to a decline in the value of a hedged currency, at
the same time, they also limit any potential gain that might result should the
value of the currency increase.

         The Fund's currency hedging will be limited to hedging involving either
specific transactions or portfolio positions. Transaction hedging is the
purchase or sale of forward currency with respect to specific receivables or
payables of the Fund generally accruing in connection with the purchase or sale
of its portfolio securities. Position hedging is the sale of forward currency
with respect to portfolio security positions. The Fund may not position hedge to
an extent greater than the aggregate market value (at the time of making such
sale) of the hedged securities.

         Securities Of Other Non-Affiliated Investment Companies. Some of the
countries in which the Small Company Fund may invest may not permit direct
investment by outside investors. investments in such countries may only be
permitted through foreign government-approved or government-authorized
investment vehicles, which may include other investment companies. Investing
through such vehicles may involve frequent or layered fees or expenses and may
also be subject to limitation under the 1940 act. Under the 1940 Act, a Fund may
invest up to 10% of its assets in shares of investment companies and up to 5% of
its assets in any one investment company as long as the investment does not
represent more than 3% of the voting stock of the acquired investment company.


                                       24

         Commercial Paper. The Small Company Fund may invest in commercial paper
which is indexed to certain specific foreign currency exchange rates. The terms
of such commercial paper provide that its principal amount is adjusted upwards
or downwards (but not below zero) at maturity to reflect changes in the exchange
rate between two currencies while the obligation is outstanding. The Fund will
purchase such commercial paper with the currency in which it is denominated and,
at maturity, will receive interest and principal payments thereon in that
currency, but the amount or principal payable by the issuer at maturity will
change in proportion to the change (if any) in the exchange rate between two
specified currencies between the date the instrument is issued and the date the
instrument matures. While such commercial paper entails the risk of loss of
principal, the potential for realizing gains as a result of changes in foreign
currency exchange rate enables the Fund to hedge or cross-hedge against a
decline in the U.S. Dollar value of investments denominated in foreign
currencies while providing an attractive money market rate of return. The Fund
will purchase such commercial paper for hedging purposes only, not for
speculation. The staff of the SEC is currently considering whether the purchase
of this type of commercial paper would result in the issuance of a "senior
security" within the meaning of the 1940 Act. The Fund believes that such
investments do not involve the creation of such a senior security, but
nevertheless will establish a segregated account with respect to its investments
in this type of commercial paper and to maintain in such account cash not
available for investment or U.S. Government securities or other liquid high
quality debt securities having a value equal to the aggregate principal amount
of outstanding commercial paper of this type.

INVESTMENT RESTRICTIONS

   
         The following are fundamental investment limitations, which cannot be
changed without the approval of the holders of a majority of the shares of the
Fund for which the change is proposed, and apply to all of the Funds of the
Trust (except the Small Company and Income Funds, whose restrictions are listed
separately below), unless otherwise stated.
    

   
The Trust may not:

         1.       Borrow money, except an amount equal to no more than 5% of the
                  value of each of the Fund's total assets (calculated when the
                  loan is made) for temporary, emergency purposes or for the
                  clearance of transactions. This limited borrowing authority
                  will not be used to leverage the Funds or to borrow for
                  extended periods of time. This authority is intended to
                  provide the investment manager additional flexibility in the
                  execution of routine daily transactions, and allow for more
                  efficient cash management.
    

   
         2.       Purchase securities on margin, but the Trust may obtain such
                  credits as may be necessary for the clearance of purchases and
                  sales of securities and except as may be necessary to make
                  margin payments in connection with derivative securities
                  transactions.
    

         3.       Make loans to other persons, except by the purchase of
                  obligations in which the Trust is authorized to invest. The
                  Trust may, however, enter into repurchase agreements, but a
                  Fund will not enter into repurchase agreements if, as a result
                  thereof, more than 10% of the Fund's total assets (taken at
                  current value) would be subject to repurchase agreements
                  maturing in more than 7 days.

   
         4.       Purchase securities of any one issuer, other than obligations
                  issued or guaranteed by the U. S. Government, its agencies or
                  instrumentalities, if, immediately after such purchase, more
                  than 5% of the Fund's total assets would be invested in such
                  issuer or the Fund would hold more than 10% the outstanding
                  voting securities of the issuer, except that 25% or less of

INVESTMENT RESTRICTIONS FOR THE SMALL COMPANY FUND AND THE INCOME FUND -- The
following are fundamental investment limitations for the Small Company and the
Income Fund which cannot be changed without shareholder approval:


THE SMALL COMPANY FUND AND THE INCOME FUND:

         1.       May (i) borrow money from banks and (ii) make other
                  investments or engage in other transactions permissible under
                  the Investment Company Act of 1940 (the "1940 Act") which may
                  involve a borrowing, provided that the combination of (i) and
                  (ii) shall not exceed 33-1/3% of the value of the Fund's total
                  assets (including the amount borrowed), less the Fund's
                  liabilities (other than borrowings), except that the Fund may
                  borrow up to an additional 5% of its total assets (not
                  including the amount borrowed) from a bank for temporary or
                  emergency purposes (but not for leverage or the purchase of
                  investments). The Fund may also borrow money from other
                  persons to the extent permitted by applicable law. For
                  purposes of this restriction, short sales, the entry into

                  futures contracts, forward commitment transactions and dollar
                  roll transactions that are not accounted for as financings
                  (and the segregation of assets in connection with any of the
                  foregoing) shall not constitute borrowing.

         2.       May not issue senior securities, except as permitted under the
                  1940 Act.

<PAGE>   88


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

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

         5.       May not lend any security or make any other loan if, as a
                  result, more than 33 1/3% of its total assets (taken at
                  current value) would be lent to other parties, except in
                  accordance with its investment objective, policies and
                  limitations through (i) purchase of debt securities or other
                  debt instruments, including loan participations, assignments
                  and structured securities, or (ii) by engaging in repurchase
                  agreements.

         6.       May not purchase the securities of any issuer if, as a result,
                  more than 25% (taken at current value) of the Fund's total
                  assets would be invested in the securities of issuers, the
                  principal activities of which are in the same industry. This
                  limitation does not apply to securities issued by the U.S.
                  government or its agencies or instrumentalities.

         7.       May not purchase or sell real estate unless acquired as a
                  result of ownership of securities or instruments, but this
                  restriction shall not prohibit the Fund from purchasing or
                  selling securities issued by entities or investment vehicles
                  that own or deal in real estate or interests therein or
                  instruments secured by real estate or interests therein.

Fund and the Income Fund which may be changed by the Board of Trustees of the
Trust without shareholder approval:

The Small Company and the Income Fund each may not:

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

         2.       Purchase securities on margin, except that the Fund may obtain
                  such short-term credits as are necessary for the clearance of
                  transactions; and provided that margin deposits in connection
                  with options, futures contracts, options on futures contracts,
                  transactions in currencies or other derivative instruments
                  shall not constitute purchasing securities on margin.

   
                  Purchase or otherwise acquire any security if, as a result,
                  more than 15% of its net assets would be invested in 
                  securities that are illiquid.

         3.       Purchase securities of other investment companies except in
                  connection with a merger, consolidation, acquisition,
                  reorganization or offer of exchange, or as otherwise permitted
                  under the 1940 Act.

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

    

         INSURANCE LAW RESTRICTIONS - In connection with the Trust's agreement
to sell shares to the Accounts, the Adviser and the insurance companies may
enter into agreements, required by certain state insurance departments, under
which the Adviser may agree to use its best efforts to assure and to permit
insurance companies to monitor that each Fund of the Trust complies with the
investment restrictions and limitations prescribed by state insurance laws and
regulations applicable to the investment of separate account assets in shares of
mutual funds. If a Fund failed to comply with such restrictions or limitations,
the Accounts would take appropriate action which might include ceasing to make
investments in the Fund or withdrawing from the state imposing the limitation.
Such restrictions and limitations are not expected to have a significant impact
on the Trust's operations.

CALCULATING YIELD - THE MONEY MARKET FUND

   
         Any current Fund yield quotations, subject to Rule 482 under the
Securities Act of 1933, shall consist of a seven calendar day historical yield,
carried at least to the nearest hundredth of a percent. The yield shall be
calculated by determining the net change, excluding realized and unrealized
gains and losses, in the value of a hypothetical pre-existing account having a
balance of one share at the beginning of the period, dividing the net change in
account value by the value of the account at the beginning of the base period to
obtain the base period return, and multiplying the base period return by 365/7
(or 366/7 during a leap year). For purposes of this calculation, the net change
in account value reflects the value of additional shares purchased with
dividends from the original share, and dividends declared on both the original
share and any such additional shares. As of June 30, 1997, the Fund's seven-day
current yield was 5.24%. The Fund's effective yield represents an annualization
of the current seven day return with all dividends reinvested, and for the
period ended June 30, 1997, was 5.38%.
    

         The Fund's yield will fluctuate daily. Actual yields will depend on
factors such as the type of instruments in the Fund's portfolio, portfolio
quality and average maturity, changes in interest rates, and the Fund's
expenses. There is no assurance that the yield quoted on any given occasion will
remain in effect for any period of time and there is no guarantee that the net
asset value will remain constant. It should be noted that a shareholder's
investment in the Fund is not guaranteed or insured. Yields of other money
market funds may not be comparable if a different base period or another method
of calculation is used.

CALCULATING YIELD AND TOTAL RETURN - NON-MONEY MARKET FUNDS

         The Funds may from time to time advertise historical performance,
subject to Rule 482 under the Securities Act of 1933. An investor should keep in
mind that any return or yield quoted represents past performance and is not a
guarantee of future results. The investment return and principal value of
investments will fluctuate so that an investor's shares, when redeemed, may be
worth more or less than their original cost.

         All performance advertisements shall include average annual total
return quotations for the most recent one, five, and ten year periods (or life,
if a fund has been in operation less than one of the prescribed periods).
Average annual total return represents the rate required each year for an
initial investment to equal the redeemable value at the end of the quoted
period. It is calculated in a uniform manner by dividing the ending redeemable
value of a hypothetical initial payment of $1,000 for a specified period of
time, by the amount of the initial payment, assuming reinvestment of all
dividends and distributions. The one, five, and ten year periods are calculated
based on periods that end on the last day of the calendar quarter preceding the
date on which an advertisement is submitted for publication.

   
         The uniformly calculated average annual total returns for the one year,
five year, and ten year periods for the Total Return and Government Bond Funds,
ended June 30, 1997 are shown below.

         The Capital Appreciation Fund began operations on May 1, 1992. Its
average annual total return for one year ended June 30, 1997, the five years
ended June 30, 1997 and for the period from May 1, 1992 through June 30, 1997
was 38.2%, 18.1% and 17.0%, respectively. The Small Company Fund began
operations on October 23, 1995. Its average total return for the year ended June
30, 1997 and period from October 23, 1995 through June 30, 1997 was 14.1% and
28.8%, respectively.

         The Government Bond Fund may also from time to time advertise a
uniformly calculated yield quotation. This yield is calculated by dividing the
net investment income per share earned during a 30-day base period by the
maximum offering price per share on the last day of the period, assuming
reinvestment of all dividends and distributions. This yield formula uses the
average number of shares entitled to receive dividends, provides for semi-annual
compounding of interest, and includes a modified market value method for
determining amortization. The yield will fluctuate, and there is no assurance
that the yield quoted on any given occasion will remain in effect for any period
of time. The Government Bond Fund yield for the 30-day period ended June 30,
1997 was 6.68%.

INVESTMENT ADVISER AND OTHER SERVICES

         The Adviser, Nationwide Advisory Services, Inc. ("NAS"), manages the
Funds (except the Small Company Fund and the Income Fund) pursuant to an
Investment Advisory Agreement (the "Agreement") dated as of November 1, 1997.
The Adviser provides the Trust with overall investment advisory services and,
subject to such policies as the Trustees may determine, makes investment
decisions for the Trust. Prior to November 1, 1997, the Adviser received a fee
computed and paid monthly at the annual rate equal to .5% of the average daily
net assets of each Fund of the Trust (except for the Small Company and Income
Funds).

         Effective November 1, 1997,the advisory fees were changed (except for
Small Company and Income Fund) to the following rates, expressed as an annual

ADVISORY SERVICES FOR THE SMALL COMPANY FUND

         The Adviser oversees the management of the Small Company Fund pursuant
to an Investment Advisory Agreement dated October 20, 1995. Subject to the
supervision and direction of the Trustees, the Adviser determines the allocation
of assets among the Subadvisers and evaluates and monitors the performance of
the Subadvisers. The Adviser is also authorized to select and place portfolio
investments on behalf of the Fund; however, the Adviser generally intends to
limit its direct portfolio management to the investment of a portion of the
Fund's assets in cash or money market instruments. The Adviser has
responsibility for communicating performance expectations and evaluations to the
Subadvisers and ultimately recommending to the Trust's Board of Trustees whether
a Subadviser's contract should be renewed, modified or terminated; however, the
Adviser does not expect to recommend frequent changes 


                                       33


<PAGE>   95


of subadvisers. The Adviser will regularly provide written reports to the Board
of Trustees regarding the results of its evaluation and monitoring functions.
The Advisory Agreement of the Small Company Fund contains termination and
indemnification provisions similar to those in the Agreement as described above.

   
         Shareholders of the Small Company Fund approved a proposal which 
authorizes the Board of Trustees to appoint, replace or terminate subadvisers 
without the approval of the Fund's shareholders; the order would also allow the 
Adviser to revise a subadvisory agreement without shareholder approval. This 
authorization will only be utilized if an exemptive order which the Adviser and 
the Trust, on behalf of the Fund, have applied for is granted by the SEC. If 
the order is granted, any change in subadvisers will be communicated to 
shareholders within 60 days of such changes and all changes will be approved by 
the Trust's Board of Trustees, including a majority of the Trustees who are not 
interested persons of the Trust or the Adviser. The order, if granted, is 
intended to facilitate the efficient operation of the Fund and afford the Trust 
increased management flexibility. Prior to receiving the exemptive order, the 
Adviser will not appoint, replace or terminate any subadvisers or materially 
amend any subadvisory agreement without obtaining the approval of shareholders.
    

         The Fund pays to the Adviser a fee at the annual rate of 1.00% of the
Fund's average daily net assets. The Adviser has voluntarily agreed to waive all
or part of its fees in order to limit the Fund's total operating expenses to not
more than 1.25% of the Fund's average daily net assets on an annual basis. These
fee waivers are voluntary and may be terminated at any time. During the year
ended December 31, 1996 and the period from October 23, 1995 (date of
commencement of operations) through December 31, 1995, the Adviser received
advisory fees in the amount of $851,352 and $11,003, respectively, and waived
fees and reimbursed expenses in the amount of $0 and $10,495, respectively.

         The Subadvisers - Pursuant to Subadvisory Agreements between each of
the Subadvisers and the Adviser, each of which are dated October 20, 1995, the
Subadvisers each manage a portion of the Fund's assets in accordance with the
Fund's investment objective and policies. With regard to the portion of the
Fund's assets allocated to it, each Subadviser shall make investment decisions
for the Fund and in connection with such decisions place purchase and sell
orders for the securities in the Fund. For the investment management services
they provide to the Fund, each Subadviser, or PIML and VEAC together, receives a
fee from the Adviser at the annual rate of .60% of the average daily net assets
of the portion of the Fund managed by that Subadviser or group of Subadvisers.

   
         During the year ended December 31, 1996 and the period from October 23
(date of commencement of operations) through December 31, 1995, the Adviser paid
$483,572 and $11,394 in fees to the Subadvisers.
    

         Each of the Subadvisory Agreements specifically provides that the
Subadviser, including its directors, officers, partners and employees, shall not
be liable for any error of judgment, or mistake of law, or for any loss arising
out of any investment, or for any act or omission in the execution and
management of the Small Company Fund, except for willful misfeasance, bad faith,
or gross negligence in the performance of its duties, or by reason of reckless
disregard of its obligations and duties under such Agreement. Each Subadvisory
Agreement will continue in effect for an initial period of two years and
thereafter shall continue automatically for successive annual periods provided
such continuance is specifically approved at least annually by the Trustees, or
by vote of a majority of the outstanding voting securities of the Fund, and in
either case, by a majority of the Trustees who are not parties to the Agreement
or interested persons of any such party. Each Subadvisory Agreement terminates
automatically if it is assigned. It may also be terminated without penalty by
vote of a majority of the out standing voting securities, or by either party, on
not more than 60 days nor less than 30 days written notice.

BROKERAGE ALLOCATIONS

         IN GENERAL. During the fiscal years ended December 31, 1996, 1995, and
1994, the Total Return Fund, paid brokerage commissions of $519,949, $377,463,
and $258,714, respectively, and the Capital Appreciation Fund paid brokerage
commissions of $196,526, $36,471, and $52,032, all to firms rendering
statistical services. The Money Market Fund and Government Bond Fund paid no
brokerage commissions during the periods covered by the financial statements.

         The Adviser (or a Subadviser) is responsible for decisions to buy and
sell securities and other investments for the Funds, the selection of brokers
and dealers to effect the transactions and the negotiation of brokerage
commissions, if any. In transactions on stock and commodity exchanges in the
United States, these commissions are negotiated, whereas on foreign stock and
commodity exchanges these commissions are generally fixed and are generally
higher than brokerage commissions in the United States. In the case of
securities traded on the OTC markets, there is generally no commission, but the
price includes a spread between the dealer's purchase and sale price which makes
up the dealer's profit. In underwritten offerings, the price includes a
disclosed, fixed commission or discount. Most short term obligations are
normally traded on a "principal" rather than agency basis. This may be done
through a dealer (e.g. securities firm or bank) who buys or sells for its own
account rather than as an agent for another client, or directly with the issuer.
A dealer's profit, if any, is the difference, or spread, between the dealer's
purchase and sale price for the obligation.

         The primary consideration in portfolio security transactions is "best
execution," i.e., execution at the most favorable prices and in the most
effective manner possible. The Adviser or Subadvisers always attempts to achieve
best execution, and it has complete freedom as to the markets in and the
broker-dealers through which it seeks this result. Subject to the requirement of
seeking best execution, securities may be bought from or sold to broker-dealers
who have furnished statistical, research, and other information or services to
the Adviser or a Subadviser. In placing orders with such broker-dealers, the
Adviser will, where possible, take into account the comparative usefulness of
such information. Such information is useful to the Adviser or a Subadviser even
though its dollar value may be indeterminable, and its receipt or availability
generally does not reduce the Adviser's or a Subadviser's normal research
activities or expenses.

         Trust portfolio transactions may be effected with broker-dealers who
have assisted investors in the purchase of Policies. However, neither such
assistance nor sale of other investment company shares is a qualifying or
disqualifying factor in a broker-dealer's selection, nor is the selection of any
broker-dealer based on the volume of shares sold.

         There may be occasions when portfolio transactions for the Trust are
executed as part of concurrent authorizations to purchase or sell the same
security for trusts or other accounts served by affiliated companies of the
Adviser or a Subadviser. Although such concurrent authorizations potentially
could be either advantageous or disadvantageous to the Trust, they are effected
only when the Adviser or a Subadviser believes that to do so is in the interest
of the Trust. When such concurrent authorizations occur, the executions will be
allocated in an equitable manner.

         The Trustees periodically review the Adviser's and each Subadviser's
performance of its responsibilities in connection with the placement of
portfolio transactions on behalf of the Fund and review the commissions paid by
the Fund over representative periods of time to determine if they are reasonable
in relation to the benefits to the Fund.

         SPECIAL BROKERAGE ALLOCATION CONSIDERATIONS RELATING TO THE SMALL
COMPANY FUND AND THE INCOME FUND. In purchasing and selling investments for
these Funds, it is the policy of each of the Subadvisers to obtain best
execution at the most favorable prices through responsible broker-dealers. In


                                       38


<PAGE>   100


selecting broker-dealers, each Subadviser will consider various relevant
factors, including, but not limited to, the size and type of the transaction;
the nature and character of the markets for the security or asset to be
purchased or sold; the execution efficiency, settlement capability, and
financial condition of the broker-dealer's firm; the broker-dealer's execution
services, rendered on a continuing basis; and the reasonableness of any
commissions. During the year ended December 31, 1996 and the period ended
December 31, 1995, the Small Company Fund paid brokerage commissions of 
$424,176 and $27,100, respectively.

         Each Subadviser may cause the Small Company or the Income Fund to pay a
broker-dealer who furnishes brokerage and/or research services a commission that
is in excess of the commission another broker-dealer would have received for
executing the transaction if it is determined that such commission is reasonable
in relation to the value of the brokerage and/or research services as defined in
Section 28(e) of the Securities Exchange Act of 1934 which have been provided.
Such research services may include, among other things, analyses and reports
concerning issuers, industries, securities, economic factors and trends, and
portfolio strategy. Any such research and other information provided by brokers
to a Subadviser is considered to be in addition to and not in lieu of services
required to be performed by the Subadviser under its subadvisory agreement with
the Adviser. The fees to each of the Subadvisers pursuant to its subadvisory
agreement with the Adviser is not reduced by reason of its receiving any
brokerage and research services. The research services provided by
broker-dealers can be useful to a Subadviser in serving its other clients or
clients of the Subadviser's affiliates. Subject to the policy of the Subadvisers
to obtain best execution at the most favorable prices through responsible
broker-dealers, a Subadviser also may consider the broker-dealer's sale of
shares of any fund for which the Subadviser serves as investment adviser,
sub-adviser or administrator.

CONSIDERATIONS RELATING TO THE SMALL COMPANY FUND. Neuberger & Berman will act
as the principal broker in the purchase and sale of portfolio securities for the
portion of the Fund advised by Neuberger & Berman and in connection with the
writing of covered call options on their securities. Transactions in portfolio
securities for which Neuberger & Berman serves as broker will be affected in
accordance with Rule 17e-1 under the 1940 Act.

         The Fund will continue to use Neuberger & Berman as its principal
broker for the portion of the Fund advised by Neuberger & Berman where, in the
judgment of Neuberger & Berman, the firm is able to obtain a price and execution
at least as favorable as that provided by other qualified brokers. To the Fund's
knowledge, however, no affiliate of Neuberger & Berman receives give-ups or
reciprocal business in connection with their securities transactions.

         Under the 1940 Act, commissions paid by the Fund to Neuberger & Berman
in connection with a purchase or sale of securities offered on a securities
exchange may not exceed the usual and customary broker's commission.
Accordingly, it is the Fund's policy that the commissions to be paid to
Neuberger & Berman must, in its judgment, be (1) at least as favorable as those
that would be charged by other brokers having comparable execution capability
and (2) at least as favorable as commissions contemporaneously charged by
Neuberger & Berman on comparable transactions for its most favored unaffiliated
customers, except for accounts for which Neuberger & Berman acts as a clearing
broker for another brokerage firm and customers of Neuberger & Berman considered
by a majority of the independent trustees not to be comparable to the Fund. The
Fund does not deem it practicable and in its best interests to solicit
competitive bids for commissions on each transaction. However, consideration
regularly is given to information concerning the prevailing level of commissions
charged on comparable transactions by other brokers during comparable periods of
time. The 1940 Act generally prohibits Neuberger & Berman from acting as
principal in the purchase or sale of securities for the Fund's account, unless
an appropriate exemption is available.

         During the year ended December 31, 1996 and the period ended December
31, 1995, the Small Company Fund paid brokerage commissions to Neuberger &
Berman in the amount of $24,069 and $4,434, respectively, representing 5.7% and
16.4%, respectively, of the total commissions paid by the Fund. The aggregate
dollar amount of transactions involving the payment of commissions to Neuberger
& Berman represented .3% and 20.2%, respectively, of total transactions on which
commissions were paid by the Fund during the periods ended December 31, 1996 and
1995.

PURCHASES, REDEMPTIONS AND PRICING OF SHARES

         An insurance company purchases shares of the Funds at their net asset
value using purchase payments received on Contracts issued by Accounts. These
Accounts are funded by shares of the Trust. For certain of the Funds, shares may
also be sold to affiliated Fund of Funds.

         All investments in the Trust are credited to the shareholder's account
in the form of full and fractional shares of the designated Fund (rounded to the
nearest 1/1000 of a share). The Trust does not issue share certificates.

         The net asset value per share of the Funds is determined once daily, as
of the close of the New York Stock Exchange (currently 4 P.M. eastern time) on
each business day the New York Stock Exchange is open and on such days as the
Board determines and on any other day during which there is a sufficient degree
of trading in each Fund's portfolio securities that the net asset value of the
Fund is materially affected by changes in the value of portfolio securities. The
Trust will not compute net asset value for the Funds on customary national
business holidays, including the following: Christmas, New Year's Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day and
Thanksgiving Day. The net asset value per share is calculated by adding the
value of all securities and other assets of a Fund, deducting its liabilities,
and dividing by the number of shares outstanding.

         The offering price for orders placed before the close of the New York
Stock Exchange, on each business day the Exchange is open for trading, will be
based upon calculation of the net asset value at the close of the Exchange. For
orders placed after the close of the Exchange, or on a day on which the Exchange
is not open for trading, the offering price is based upon net asset value at the
close of the Exchange on the next day thereafter on which the Exchange is open
for trading. The net asset value of a share of each Fund on which offering and
redemption prices are based is the net asset value of that Fund, divided by the
number of shares outstanding, the result being adjusted to the nearer cent. The
net asset value of each Fund is determined by subtracting the liabilities of the
Fund from the value of its assets (chiefly composed of investment securities).
Securities of the Fund listed on national exchanges are valued at the last sales
price on the principal exchange, or if there is no sale on that day, or if the
securities are traded only in the over-the-counter market, at the quoted bid
prices. Securities and other assets, for which such market prices are
unavailable, are valued at fair value as determined by the Trustees. For the
Money Market Fund, all securities are valued at amortized cost, which
approximates market value, in accordance with Rule 2a-7 of the Investment
Company Act of 1940.

         The net income of the Money Market Fund is determined once daily, as of
the close of the New York Stock Exchange (currently 4:00 P.M., New York time) on
each business day on which such Exchange is open. All the net income of the
Fund, so determined, is declared in shares as a dividend to shareholders of
record at the time of such determination. (Shares purchased become entitled to
dividends declared as of the first day following the date of investment.)
Dividends are distributed in the form of additional shares of the Fund on the
last business day of each month at the rate of one share (and fraction thereof)
of the Fund for each one dollar (and fraction thereof) of dividend income.

         For this purpose, the net income of the Money Market Fund (from the
time of the immediately preceding determination thereof) shall consist of: (a)
all interest income accrued on the portfolio assets 


                                       40


<PAGE>   102


of the Fund, (b) less all actual and accrued expenses and (c) plus or minus net
realized gains and losses on the assets of the Fund determined in accordance
with generally accepted accounting principles. Interest income shall include
discount earned (including both original issue and market discount) on discount
paper accrued ratably to the date of maturity. Securities are valued at market
or amortized cost which approximates market, which the Trustees have determined
in good faith constitutes fair value for the purposes of complying with the
Investment Company Act of 1940.

         Because the net income of the Money Market Fund is declared as a
dividend each time the net income is determined, the net asset value per share
(i.e., the value of the net assets of the Fund divided by the number of shares
outstanding) remains at one dollar per share immediately after each such
determination and dividend declaration. Any increase in the value of a
shareholder's investment in the Fund, representing the reinvestment of dividend
income, is reflected by an increase in the number of shares of the Fund in its
account.

         Pursuant to its objective of maintaining a fixed one dollar share
price, the Fund will not purchase securities with a remaining maturity of more
than 397 days and will maintain a dollar weighted average portfolio maturity of
90 days or less.

         An insurance company separate account redeems shares to make benefit or
surrender payments under the terms of its Policies. Redemptions are processed on
any day on which the Trust is open for business and are effected at net asset
value next determined after the redemption order, in proper form, is received by
the Trust's transfer agent, NIS.

         The Trust may suspend the right of redemption for such periods as are
permitted under the 1940 Act and under the following unusual circumstances: (a)
when the New York Stock Exchange is closed (other than weekends and holidays) or
trading is restricted; (b) when an emergency exists, making disposal of
portfolio securities or the valuation of net assets not reasonably practicable;
or (c) during any period when the Securities and Exchange Commission has by
order permitted a suspension of redemption for the protection of shareholders.

ADDITIONAL INFORMATION

         DESCRIPTION OF SHARES - The Declaration of Trust permits the Trustees
to issue an unlimited number of full and fractional shares of beneficial
interest of each Fund and to divide or combine such shares into a greater or
lesser number of shares without thereby exchanging the proportionate beneficial
interests in the Trust. Each share of a Fund represents an equal proportionate
interest in that Fund with each other share. The Trust reserves the right to
create and issue a number of series of shares. In that case, the shares of each
series would participate equally in the earnings, dividends, and assets of the
particular series, but shares of all series would vote together in the election
of Trustees. Upon liquidation of a Fund, shareholders are entitled to share pro
rata in the election of Trustees. Upon liquidation of a Fund, shareholders are
entitled to share pro rata in the net assets of such Fund available for
distribution to shareholders.

         VOTING RIGHTS - Shareholders are entitled to one vote for each share
held. Shareholders may vote in the election of Trustees and on other matters
submitted to meetings of shareholders. No amendment may be made to the
Declaration of Trust without the affirmative vote of a majority of the
outstanding shares of the Trust. The Trustees may, however, amend the
Declaration of Trust without the vote or consent of shareholders to:

                     -  designate series of the Trust; or

                     -  change the name of the Trust; or


                                       41


<PAGE>   103


                - supply any omission, cure, correct, or supplement any 
                  ambiguous, defective, or inconsistent provision to conform the
                  Declaration of Trust to the requirements of applicable federal
                  laws or regulations if they deem it necessary.

         Shares have no pre-emptive or conversion rights. Shares are fully paid
and nonassessable, except as set forth below. In regard to termination, sale of
assets, or change of investment restrictions, the right to vote is limited to
the holders of shares of the particular Fund affected by the proposal. When a
majority is required, it means the lesser of 67% or more of the shares present
at a meeting when the holders of more than 50% of the outstanding shares are
present or represented by proxy, or more than 50% of the outstanding shares.

         SHAREHOLDER INQUIRIES - All inquiries regarding the Trust should be
directed to the Trust at the telephone number or address shown on the cover page
of this Prospectus.




TAX STATUS

         Nationwide Life Insurance Company and Nationwide Life and Annuity
Insurance are currently the sole shareholders of record for each Fund of the
Trust. Each Fund of the Trust is treated as a separate entity for purpose of the
regulated investment company provisions of the Internal Revenue Code, and,
therefore, the assets, income, and distributions of each Fund are considered
separately for purposes of determining whether or not the Fund qualifies as a
regulated investment company.

         Each Fund of the Trust intends to qualify as a "regulated investment
company" under Subchapter M of the Code. If it qualifies as a regulated
investment company, a Fund will pay no federal income taxes on its taxable net
investment income (that is, taxable income other than net realized capital
gains) and its net realized capital gains that are distributed to shareholders.
To qualify under Subchapter M, a Fund must, among other things: (i) distribute
to its shareholders at least 90% of its taxable net investment income (for this
purpose consisting of taxable net investment income and net realized short-term
capital gains); (ii) derive at least 90% of its gross income from dividends,
interest, payments with respect to loans of securities, gains from the sale or
other disposition of securities, or other income (including, but not limited to,
gains from options, futures, and forward contracts) derived with respect to its
business of investing in securities; (iii) diversify its holdings so that, at
the end of each fiscal quarter of the Fund (a) at least 50% of the market value
of the Fund assets is represented by cash, U.S. government securities and other
securities, with those other securities limited, with respect to any one issuer,
to an amount no greater in value than 5% of the Fund's total assets and to not
more than 10% of the outstanding voting securities of the issuer, and (b) not
more than 25% of the market value of the Fund's assets is invested in the
securities of any one issuer (other than U.S. government securities or
securities of other regulated investment companies) or of two or more issuers
that the Fund controls and that are determined to be in the same or similar
trades or businesses or related trades or businesses. In meeting these
requirements, a Fund may be restricted in the selling of securities held by the
Fund for less than three months and in the utilization of certain of the
investment techniques described above and in the respective Fund's Prospectus.
As a regulated investment company, a Fund will be subject to a 4% non-deductible
excise tax measured with respect to certain undistributed amounts of ordinary
income and capital gain required to be but not distributed under a prescribed
formula. The formula requires payment to shareholders during a calendar year of
distributions representing at least 98% of the Fund's taxable ordinary income
for the calendar year and at least 98% of the excess of its capital gains over
capital losses realized during the one-year period ending October 31 during such
year, together with any undistributed, untaxed amounts of ordinary income and
capital gains from the previous calendar 


                                       42


<PAGE>   104


year. The Funds expect to pay the dividends and make the distributions necessary
to avoid the application of this excise tax.

         In addition, each Fund intends to comply with the diversification
requirements of Section 817(h) of the Code related to the tax-deferred status of
insurance company separate accounts. To comply with regulations under Section
817(h) of the code, each Fund will be required to diversify its investments so
that on the last day of each calendar quarter no more than 55% of the value of
its assets is represented by any one investment, no more than 70% is represented
by any two investments, no more than 80% is represented by any three investments
and no more than 90% is represented by any four investments. Generally, all
securities of the same issuer are treated as a single investment. For the
purposes of Section 817(h), obligations of the United States Treasury and each
U.S. government instrumentality are treated as securities of separate issuers.
The Treasury Department has indicated that it may issue future pronouncements
addressing the circumstances in which a Policy owner's control of the
investments of a separate account may cause the Policy owner, rather than the
participating insurance company, to be treated as the owner of the assets held
by the separate account. If the Policy owner is considered the owner of the
securities underlying the separate account, income and gains produced by those
securities would be included currently in the Policy owner's gross income. It is
not known what standards will be set forth in such pronouncements or when, if at
all, these pronouncements may be issued. In the event that rules or regulations
are adopted, there can be no assurance that the Funds will be able to operate as
currently described, or that the Trust will not have to change the investment
goal or investment policies of a Fund. The board reserves the right to modify
the investment policies of a Fund as necessary to prevent any such prospective
rules and regulations from causing a Policy owner to be considered the owner of
the shares of the Fund underlying the separate account.

TAX CONSEQUENCES FOR THE SMALL COMPANY FUND

         Foreign Transactions. Dividends and interest received by the Small
Company Fund may be subject to income, withholding, or other taxes imposed by
foreign countries and U.S. possessions that would reduce the yield on its
securities. Tax conventions between certain countries and the United States may
reduce or eliminate these foreign taxes, however, and many foreign countries do
not impose taxes on capital gains in respect of investments by foreign
investors. Policy holders will bear the cost of foreign tax withholding in the
form of increased expenses to the Fund but generally will not be able to claim a
foreign tax credit or deduction for foreign taxes paid by the Fund by reason of
the tax-deferred status of the policies.

         The Fund's transactions, if any, in foreign currencies, forward
contracts, options and futures contracts (including options and forward
contracts on foreign currencies) will be subject to special provisions of the
Code that, among other things, may affect the character of gains and losses
recognized by the Fund (i.e., may affect whether gains or losses are ordinary or
capital), accelerate recognition of income to the Fund, defer Fund losses and
cause the fund to be subject to hyperinflationary currency rules. These rules
could therefore affect the character, amount and timing of distributions to
shareholders. These provisions also (a) will require the Fund to mark-to-market
certain types of its positions (i.e., treat them as if they were closed out) and
(b) may cause the fund to recognize income without receiving cash with which to
pay dividends or make distributions in amounts necessary to satisfy the
distribution requirements for avoiding income and excise taxes. The Fund will
monitor its transactions, will make the appropriate tax elections and will make
the appropriate entries in its books and records when it acquires any foreign
currency, forward contract, option, futures contract or hedged investment so
that (i) neither the Fund nor its shareholders will be treated as receiving a
materially greater amount of capital gains or distributions than actually
realized or received, (ii) the Fund will be able to use substantially all of its
losses for the fiscal years in which the losses actually occur, and (iii) the
Fund will continue to qualify as a regulated investment company.

<PAGE>   105


         As described in the Prospectus, because shares of the Fund may only be
purchased through Policies, it is anticipated that dividends and distributions
will be exempt from current taxation if left to accumulate within the Policies.

         Investment in Passive Foreign Investment Companies. If the Fund
purchases shares in certain foreign entities classified under the Code as
"passive foreign investment companies" ("PFICs"), the Fund may be subject to
federal income tax on a portion of an "excess distribution" or gain from the
disposition of the shares, even though the income may have to be distributed by
the Fund to its shareholders, the Policies. In addition, gain on the disposition
of shares in a PFIC generally is treated as ordinary income even though the
shares are capital assets in the hands of the Fund. Certain interest charges may
be imposed on the Fund with respect to any taxes arising from excess
distributions or gains on the disposition of shares in a PFIC.

         The Fund may be eligible to elect to include in its gross income its
share of earnings of a PFIC on a current basis. Generally, the election would
eliminate the interest charge and the ordinary income treatment on the
disposition of stock, but such an election may have the effect of accelerating
the recognition of income and gains by the Fund compared to a fund that did not
make the election. In addition, information required to make such an election
may not be available to the Fund.

         Regulations of the Internal Revenue Service (the "IRS") provide a
mark-to-market election for shares in certain PFICs held by regulated investment
companies. If the Fund makes the election, it may be able to avoid the interest
charge (but not the ordinary income treatment) on disposition of the PFIC stock
by each year marking-to-market the stock (that is, by treating it as if it were
sold for fair market value on the last day of the year). Such an election could
also result in acceleration of income to the Fund.

         Derivative Instruments. The use of derivatives strategies, such as
purchasing and selling (writing) options and futures and entering into forward
currency contracts, involves complex rules that will determine for income tax
purposes the character and timing of recognition of the gains and losses the
Small Company Fund realizes in connection therewith. Gains from the disposition
of foreign currencies (except certain gains therefrom that may be excluded by
future regulations), and income from transactions in options, futures, and
forward currency contracts derived by the Fund with respect to its business of
investing in securities or foreign currencies, will qualify as permissible
income. However, income from the disposition of options and futures (other than
those on foreign currencies) will be subject to a 30% limitation if they are
held for less than three months. Income from the disposition of foreign
currencies, and options, futures, and forward contracts on foreign currencies,
that are not directly related to the Fund's principal business of investing in
securities (or options and futures with respect to securities) also will be
subject to a 30% limitation if they are held for less than three months.

         If the Fund satisfies certain requirements, any increase in value of a
position that is part of a "designated hedge" will be offset by any decrease in
value (whether realized or not) for the offsetting hedging position during the
period of the hedge for purposes of determining whether the Fund satisfies the
30% limitation on the gross income that can be derived from the sale or other
disposition of securities or derivative instruments that were held for less than
three months. Thus, only the net gain (if any) from the designated hedge will be
included in gross income for purposes of that limitation. The Fund intends that,
when it engages in hedging strategies, the hedging transactions will qualify for
this treatment, but at the present time it is not clear whether this treatment
will be available for all of the Fund's hedging transactions. To the extent this
treatment is not available or is not elected by the Fund, it may be forced to
defer the closing out of certain options, futures, or forward currency contracts
beyond the time when it otherwise would be advantageous to do so, in order for
the Fund to continue to qualify as a RIC.

TAX CONSEQUENCES TO SHAREHOLDERS

         Since shareholders of the Funds will be the Accounts, no discussion is
included herein as to the Federal income tax consequences at the level of the
holders of the Contracts. For information concerning the Federal income tax
consequences to such holders, see the Prospectuses for such Contracts.

                                   APPENDIX A

                                  BOND RATINGS

                         STANDARD & POOR'S DEBT RATINGS

         A Standard & Poor's corporate or municipal debt rating is a current
assessment of the creditworthiness of an obligor with respect to a specific
obligation. This assessment may take into consideration obligors such as
guarantors, insurers, or lessees.

         The debt rating is not a recommendation to purchase, sell, or hold a
security, inasmuch as it does not comment as to market price or suitability for
a particular investor. The ratings are based on current information furnished by
the issuer or obtained by Standard & Poor's from other sources it considers
reliable. Standard & Poor's does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information. The
ratings may be changed, suspended, or withdrawn as a result of changes in, or
unavailability of, such information, or for other circumstances.

         The ratings are based, in varying degrees, on the following
considerations:

- - 1. Likelihood of default - capacity and willingness of the obligor as to the
timely payment of interest and repayment of principal in accordance with the
terms of the obligation.

- - 2. Nature of and provisions of the obligation.

         Protection afforded by, and relative position of, the obligation in the
         event of bankruptcy, reorganization, or other arrangement under the
         laws of bankruptcy and other laws affecting creditors' rights.

INVESTMENT GRADE

         AAA - Debt rated 'AAA' has the highest rating assigned by Standard &
Poor's. Capacity to pay interest and repay principal is extremely strong.

         AA - Debt rated 'AA' has a very strong capacity to pay interest and
repay principal and differs from the highest rated issues only in small degree.

         A - Debt rated 'A' has a strong capacity to pay interest and repay
principal although it is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than debt in higher rated
categories.

         BBB - Debt rated 'BBB' is regarded as having an adequate capacity to
pay interest and repay principal. Whereas it normally exhibits adequate
protection parameters, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity to pay interest and repay principal
for debt in this category than in higher rated categories.

SPECULATIVE GRADE

         Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded as having
predominantly speculative characteristics with respect to capacity to pay
interest and repay principal. 'BB' indicates the least degree of speculation and
'C' the highest. While such debt will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions.


                                       46


<PAGE>   108


         BB - Debt rated 'BB' has less near-term vulnerability to default than
other speculative issues. However, it faces major ongoing uncertainties or
exposure to adverse business, financial, or economic conditions which could lead
to inadequate capacity to meet timely interest and principal payments. The 'BB'
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied 'BBB-' rating.

         B - Debt rated 'B' has a greater vulnerability to default but currently
has the capacity to meet interest payments and principal repayments. Adverse
business, financial, or economic conditions will likely impair capacity or
willingness to pay interest and repay principal. The 'B' rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
'BB' or 'BB-' rating.

         CCC - Debt rated 'CCC' has a currently identifiable vulnerability to
default, and is dependent upon favorable business, financial, and economic
conditions to meet timely payment of interest and repayment of principal. In the
event of adverse business, financial, or economic conditions, it is not likely
to have the capacity to pay interest and repay principal. The 'CCC' rating
category is also used for debt subordinated to senior debt that is assigned an
actual or implied 'B' or 'B-' rating.

         CC - Debt rated 'CC' typically is applied to debt subordinated to
senior debt that is assigned an actual or implied 'CCC' rating.

         C - Debt rated 'C' typically is applied to debt subordinated to senior
debt which is assigned an actual or implied 'CCC-' debt rating. The 'C' rating
may be used to cover a situation where a bankruptcy petition has been filed, but
debt service payments are continued.

         CI - The rating 'CI' is reserved for income bonds on which no interest
is being paid.

         D - Debt rated 'D' is in payment default. The 'D' rating category is
used when interest payments or principal payments are not made on the date due
even if the applicable grace period has not expired, unless Standard & Poor's
believes that such payments will be made during such grade period. The 'D'
rating also will be used upon the filing of a bankruptcy petition if debt
service payments are jeopardized.

                         MOODY'S LONG-TERM DEBT RATINGS

         Aaa - Bonds which are rated Aaa are judged to be of the best quality.
They carry the smallest degree of investment risk and are generally referred to
as "gilt edged." Interest payments are protected by a large or by an
exceptionally stable margin and principal is secure. While the various
protective elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

         Aa - Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risk appear somewhat larger than in Aaa securities.

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

         Baa - Bonds which are rated Baa are considered as medium-grade
obligations (i.e., they are neither highly protected nor poorly secured).
Interest payments and principal security appear adequate for the 


                                       47


<PAGE>   109


present but certain protective elements may be lacking or may be
characteristically unreliable over any great length of time. Such bonds lack
outstanding investment characteristics and in fact have speculative
characteristics as well.

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

         B - Bonds which are rated B generally lack characteristics of the
desirable investment. Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small.

         Caa - Bonds which are rated Caa are of poor standing. Such issues may
be in default or there may be present elements of danger with respect to
principal or interest.

         Ca - Bonds which are rated Ca represent obligations which are
speculative in a high degree. Such issues are often in default or have other
marked shortcomings.

         C - Bonds which are rated C are the lowest rated class of bonds, and
issues so rated can be regarded as having extremely poor prospects of ever
attaining any real investment standing.

                   FITCH INVESTORS SERVICE, INC. BOND RATINGS

         Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
represent Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt in a timely manner.

         The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength and credit quality.

         Fitch ratings do not reflect any credit enhancement that may be
provided by insurance policies or financial guaranties unless otherwise
indicated.

         Bonds that have the same rating are of similar but not necessarily
identical credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.

         Fitch ratings are not recommendations to buy, sell, or hold any
security. ratings do not comment on the adequacy of market price, the
suitability of any security for a particular investor, or the tax-exempt nature
or taxability of payments made in respect of any security.

         Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such
information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.

AAABonds considered to be investment grade and of the highest credit quality.
         The obligor has an exceptionally strong ability to pay interest and
         repay principal, which is unlikely to be affected by reasonably
         foreseeable events.

         AABonds considered to be investment grade and of very high credit
         quality. The obligor's ability to pay interest and repay principal is
         very strong, although not quite as strong as bonds rated 'AAA'. Because
         bonds rated in the 'AAA' and 'AA' categories are not significantly
         vulnerable to foreseeable future developments, short-term debt of the
         issuers is generally rated 'F-1+'.

         ABonds considered to be investment grade and of high credit quality.
         The obligor's ability to pay interest and repay principal is considered
         to be strong, but may be more vulnerable to adverse changes in economic
         conditions and circumstances than bonds with higher ratings.

         BBBBonds considered to be investment grade and of satisfactory credit
         quality. The obligor's ability to pay interest and repay principal is
         considered to be adequate. Adverse changes in economic conditions and
         circumstances, however, are more likely to have adverse impact on these
         bonds, and therefore, impair timely payment. The likelihood that the
         ratings of these bonds will fall below investment grade is higher than
         for bonds with higher ratings.

         Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
('BB' to 'C') represent Fitch's assessment of the likelihood of timely payment
of principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ('DDD' to 'D') is an
assessment of the ultimate recovery value through reorganization or liquidation.

         The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength.

         Bonds that have the same rating are of similar but not necessarily
identical credit quality since the rating categories cannot fully reflect the
differences in the degrees of credit risk.

         BBBonds are considered speculative. The obligor's ability to pay
         interest and repay principal may be affected over time by adverse
         economic changes. However, business and financial alternatives can be
         identified which could assist the obligor in satisfying its debt
         service requirements.

         BBonds are considered highly speculative. While bonds in this class are
         currently meeting debt service requirements, the probability of
         continued timely payment of principal and interest reflects the
         obligor's limited margin of safety and the need for reasonable business
         and economic activity throughout the life of the issue.

         CCCBonds have certain identifiable characteristics which, if not
         remedied, may lead to default. The ability to meet obligations requires
         an advantageous business and economic environment.

         CCBonds are minimally protected. Default in payment of interest and/or
         principal seems probable over time.

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

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

                   DUFF & PHELPS, INC. LONG-TERM DEBT RATINGS

         These ratings represent a summary opinion of the issuer's long-term
fundamental quality. Rating determination is based on qualitative and
quantitative factors which may vary according to the basic economic and
financial characteristics of each industry and each issuer. Important
considerations are vulnerability to economic cycles as well as risks related to
such factors as competition, government action, regulation, technological
obsolescence, demand shifts, cost structure, and management depth and expertise.
The projected viability of the obligor at the trough of the cycle is a critical
determination.

         Each rating also takes into account the legal form of the security,
(e.g., first mortgage bonds, subordinated debt, preferred stock, etc.). The
extent of rating dispersion among the various classes of securities is
determined by several factors including relative weightings of the different
security classes in the capital structure, the overall credit strength of the
issuer, and the nature of covenant protection. Review of indenture restrictions
is important to the analysis of a company's operating and financial constraints.

         The Credit Rating Committee formally reviews all ratings once per
quarter (more frequently, if necessary). Ratings of 'BBB-' and higher fall
within the definition of investment grade securities, as defined by bank and
insurance supervisory authorities.

                               SHORT-TERM RATINGS

                   STANDARD & POOR'S COMMERCIAL PAPER RATINGS

         A Standard & Poor's commercial paper rating is a current assessment of
the likelihood of timely payment of debt considered short-term in the relevant
market.

         Ratings are graded into several categories, ranging from 'A-1' for the
highest quality obligations to 'D' for the lowest. These categories are as
follows:

         A-1 This highest category indicates that the degree of safety regarding
timely payment is strong. Those issues determined to possess extremely strong
safety characteristics are denoted with a plus sign (+) designation.

         A-2 Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated 'A-1'.

         A-3 Issues carrying this designation have adequate capacity for timely
payment. They are, however, more vulnerable to the adverse effects of changes in
circumstances than obligations carrying the higher designations.

         B Issues rated 'B' are regarded as having only speculative capacity for
timely payment.

         C This rating is assigned to short-term debt obligations with doubtful
capacity for payment.

         D Debt rated 'D' is in payment default. the 'D' rating category is used
when interest payments or principal payments are not made on the date due, even
if the applicable grace period has not expired, unless Standard & Poor's
believes that such payments will be made during such grade period.

                         STANDARD & POOR'S NOTE RATINGS

         An S&P note rating reflects the liquidity factors and market-access
risks unique to notes. Notes maturing in three years or less will likely receive
a note rating. Notes maturing beyond three years will most likely receive a
long-term debt rating.

         The following criteria will be used in making the assessment:

         -        Amortization schedule - the larger the final maturity relative
                  to other maturities, the more likely the issue is to be
                  treated as a note.

         -        Source of payment - the more the issue depends on the market
                  for its refinancing, the more likely it is to be considered a
                  note.


                                       51


<PAGE>   113

         Note rating symbols and definitions are as follows:

         SP-1 Strong capacity to pay principal and interest. Issues determined
to possess very strong characteristics are given a plus (+) designation.

         SP-2 Satisfactory capacity to pay principal and interest, with some
vulnerability to adverse financial and economic changes over the term of the
notes.

         SP-3 Speculative capacity to pay principal and interest.

                           MOODY'S SHORT-TERM RATINGS

         Moody's short-term debt ratings are opinions on the ability of issuers
to repay punctually senior debt obligations. These obligations have an original
maturity not exceeding one year, unless explicitly noted. Moody's employs the
following three designations, all judged to be investment grade, to indicate the
relative repayment capacity of rated issuers:

         Issuers rated Prime-1 (or supporting institutions) have a superior
capacity for repayment of senior short-term debt obligations. Prime-1 repayment
capacity will normally be evidenced by the following characteristics: (I)
leading market positions in well established industries, (II) high rates of
return on funds employed, (III) conservative capitalization structures with
moderate reliance on debt and ample asset protection, (IV) broad margins in
earnings coverage of fixed financial charges and high internal cash generation,
and (V) well established access to a range of financial markets and assured
sources of alternative liquidity.

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

         Issuers rated Prime-3 (or supporting institutions) have an acceptable
capacity for repayment of short-term promissory obligations. The effect of
industry characteristics and market composition may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.

         Issuers rated Not Prime do not fall within any of the prime rating
categories.

                              MOODY'S NOTE RATINGS

         MIG 1/VMIG 1 This designation denotes best quality. There is present
strong protection by established cash flows, superior liquidity support or
demonstrated broad based access to the market for refinancing.

         MIG 2/VMIG 2 This designation denotes high quality. Margins of
protection are ample although not so large as in the preceding group.


                                       52


<PAGE>   114

  
         MIG 3/VMIG 3 This designation denotes favorable quality. All security
elements are accounted for but there is lacking the undeniable strength of the
preceding grades. Liquidity and cash flow protection may be narrow and market
access for refinancing is likely to be less well established.

         MIG 4/VMIG 4 This designation denotes adequate quality. Protection
commonly regarded as required of an investment security is present and although
not distinctly or predominantly speculative, there is specific risk.

         SG This designation denotes speculative quality. Debt instruments in
this category lack margins of protection.

                           FITCH'S SHORT-TERM RATINGS

         Fitch's short-term ratings apply to debt obligations that are payable
on demand or have original maturities of generally up to three years, including
commercial paper, certificates of deposit, medium-term notes, and municipal and
investment notes.

         The short-term rating places greater emphasis than a long-term rating
on the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.

                           F-1+ Exceptionally strong credit quality. Issues
                  assigned this rating are regarded as having the strongest
                  degree of assurance for timely payment.

                           F-1 Very strong credit quality. Issues assigned this
                  rating reflect an assurance of timely payment only slightly
                  less in degree than issues rated 'f-1+'.

                           F-2 Good credit quality. Issues assigned this rating
                  have a satisfactory degree of assurance for timely payment but
                  the margin of safety is not as great as for issues assigned
                  'F-1+' and 'F-1' ratings.

                           F-3 Fair credit quality. Issues assigned this rating
                  have characteristics suggesting that the degree of assurance
                  for timely payment is adequate, however, near-term adverse
                  changes could cause these securities to be rated below
                  investment grade.

                           F-S Weak credit quality. Issues assigned this rating
                  have characteristics suggesting a minimal degree of assurance
                  for timely payment and are vulnerable to near-term adverse
                  changes in financial and economic conditions.

                           D Default. Issues assigned this rating are in actual
                  or imminent payment default.


                           LOC The symbol LOC indicates that the rating is based
                  on a letter of credit issued by a commercial bank.


                      DUFF & PHELPS SHORT-TERM DEBT RATINGS

         Duff & Phelps' short-term ratings are consistent with the rating
criteria utilized by money market participants. The ratings apply to all
obligations with maturities under one year, including commercial paper, the
uninsured portion of certificates of deposit, unsecured bank loans, master
notes, bankers 


                                       53

acceptances, irrevocable letters of credit, and current maturities of long-term
debt. Asset-backed commercial paper is also rated according to this scale.

         Emphasis is placed on liquidity which is defined as not only cash from
operations, but also access to alternative sources of funds including trade
credit, bank lines, and the capital markets. An important consideration is the
level of an obligor's reliance on short-term funds on an ongoing basis.

RATING SCALE      DEFINITION

                  High Grade

                  D-1+ Highest certainty of timely payment. short-term
                  liquidity, including internal operating factors and/or access
                  to alternative sources of funds, is outstanding, and safety is
                  just below risk-free U.S. Treasury short-term obligations.

                  D-1 Very high certainty of timely payment. Liquidity factors
                  are excellent and supported by good fundamental protection
                  factors. Risk factors are minor.

                  D-1- High certainty of timely payment. Liquidity factors are
                  strong and supported by good fundamental protection factors.
                  Risk factors are very small.

                  Good Grade

                  D-2 Good certainty of timely payment. Liquidity factors and
                  company fundamentals are sound. Although ongoing funding needs
                  may enlarge total financing requirements, access to capital
                  markets is good. Risk factors are small.

                           Satisfactory Grade

                  D-3 Satisfactory liquidity and other protection factors
                  qualify issue as to investment grade. Risk factors are larger
                  and subject to more variation. Nevertheless, timely payment is
                  expected.

                           Non-investment Grade

                  D-4 Speculative investment characteristics. Liquidity is not
                  sufficient to insure against disruption in debt service.
                  Operating factors and market access may be subject to a high
                  degree of variation.

                           Default

                  D-5 Issuer failed to meet scheduled principal and/or interest
                  payments.


                          THOMSON'S SHORT-TERM RATINGS

         The Thomson Short-Term Ratings apply, unless otherwise noted, to
specific debt instruments of the rated entities with a maturity of one year or
less. Thomson short-term ratings are intended to assess the likelihood of an
untimely or incomplete payments of principal or interest.

         TBW-1 the highest category, indicates a very high likelihood that
principal and interest will be paid on a timely basis.

         TBW-2 the second highest category, while the degree of safety regarding
timely repayment of principal and interest is strong, the relative degree of
safety is not as high as for issues rated "TBW-1".

         TBW-3 the lowest investment-grade category; indicates that while the
obligation is more susceptible to adverse developments (both internal and
external) than those with higher ratings, the capacity to service principal and
interest in a timely fashion is considered adequate.


                                       54

         TBW-4 the lowest rating category; this rating is regarded as
non-investment grade and therefore speculative.


                             IBCA SHORT-TERM RATINGS

         IBCA short-term ratings assess the borrowing characteristics of banks
and corporations, and the capacity for timely repayment of debt obligations. The
short-term ratings relate to debt which has a maturity of less than one year.

         IBCA issues ratings and reports on the largest U.S. and international
bank holding companies, as well as major investment banks. IBCA's short-term
rating system utilizes a dual system--Individual Ratings and Legal Ratings. The
Individual Rating addresses 1) the current strength of consolidated banking
companies and their principal bank subsidiaries. A consolidated bank holding
company/bank with an "A" rating has a strong balance sheet, and a favorable
credit profile without significant problems. A "B" rating indicates sound credit
profile without significant problems. Performance is generally in line with or
better than that of its peers. The legal rating addresses the question of
whether an institution would receive support if it ran into difficulties. Issues
rated "A-1" are obligations supported by a very strong capacity for timely
repayment. Issues rated "A-2" have a very strong capacity for timely repayment
although such capacity may be susceptible to adverse changes in business,
economic or financial conditions.

                           A1+ Obligations supported by the highest capacity for
                  timely repayment and possess a particularly strong credit
                  feature.

                           A1 Obligations supported by the highest capacity for
                  timely repayment.

                           A2 Obligations supported by a good capacity for
                  timely repayment.

                           A3 Obligations supported by a satisfactory capacity
                  for timely repayment.

                           B Obligations for which there is an uncertainty as to
                  the capacity to ensure timely repayment.

                           C Obligations for which there is a high risk of
                  default or which are currently in default.

                           D Obligations which are currently in default.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Nationwide Separate Account Trust (Trust) is a diversified, open-end investment
company registered under the Investment Company Act of 1940, as amended. The
Trust offers shares only to life insurance company separate accounts to fund the
benefits under variable insurance or annuity policies issued by life insurance
companies. The Trust was organized as a Massachusetts Trust effective June 30,
1981. To date, only separate accounts of Nationwide Life Insurance Company and
Nationwide Life and Annuity Insurance Company (formerly Financial Horizons Life
Insurance Company), which are affiliated companies, have purchased shares.
 
The Trust offers shares in five series: Small Company Fund, Capital Appreciation
Fund, Total Return Fund, Government Bond Fund and Money Market Fund. The Trust
was amended in 1995 to create the Small Company Fund. On October 23, 1995, the
Small Company Fund was capitalized through the sale of shares to Nationwide Life
Insurance Company in the amount of $5,000,000, at which time the Small Company
Fund became effective and sales of shares commenced.
 
On January 4, 1997, the Nationwide Separate Account Trust Income Fund became
effective. The Fund has not commenced operations.
 
USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
SECURITY VALUATION
 
A) SMALL COMPANY, CAPITAL APPRECIATION, TOTAL RETURN AND GOVERNMENT BOND
 
  Securities are valued at the closing price of the securities exchange on which
  such securities are primarily traded. Listed securities for which no sale was
  reported on the valuation date are valued at quoted bid prices. Securities not
  listed on an exchange or for which there were no transactions are valued at
  their most recent bid price, or where no prices are available, at fair market
  value, using procedures authorized by the Board of Trustees. Investments
  denominated in foreign currencies are translated to U.S. dollars at prevailing
  exchange rates. Forward currency exchange contracts are also valued at the
  prevailing exchange rates.
 
  The value of a repurchase agreement generally equals the purchase price paid
  by the Fund (cost) plus the interest accrued to date. The seller, under the
  repurchase agreement, is required to maintain the market value of the
  underlying collateral at not less than the value of the repurchase agreement.
  Securities subject to repurchase agreements are held by the Federal
  Reserve/Treasury book-entry system or by the Fund's custodian or an approved
  sub-custodian.
 
B) MONEY MARKET
 
  Securities are valued at amortized cost, which approximates market value, in
  accordance with Rule 2a-7 of the Investment Company Act of 1940.

- --------------------------------------------------------------------------------
 
FOREIGN CURRENCY TRANSACTIONS (SMALL COMPANY FUND)
 
Fluctuation in the value of investments resulting from changes in foreign
exchange rates are included with net realized and unrealized gain or loss from
investments.
 
Net realized foreign exchange gains or losses arise from sales of foreign
currencies, currency gains or losses realized on security transactions and the
difference between the amounts of dividends, interest and foreign withholding
taxes recorded on the Fund's books, and the U.S. dollar equivalent of amounts
actually received or paid. Net unrealized foreign exchange gains or losses arise
from changes in the value of assets and liabilities resulting from changes in
exchange rates.
 
The Fund enters into forward currency exchange contracts which are obligations
to purchase or sell a foreign currency at a specified rate on a certain date in
the future. A net realized gain or loss would be incurred if the value of the
contract increases or decreases between the date the contract is opened and the
date it is closed. Forward currency contracts are marked to market daily and
this change in value is reflected in the Statement of Assets and Liabilities as
a net receivable or payable for foreign currency contracts purchased.
 
At or before the closing of a forward contract, the Small Company Fund may
either sell a portfolio security and make delivery of the currency, or retain
the security and fully or partially offset its contractual obligation to deliver
the currency by purchasing a second contract. If the Fund retains the portfolio
security and engages in an offsetting transaction, the Fund, at the time of
execution of the offsetting transaction, will incur a gain or loss to the extent
that movement has occurred in forward contract prices.
 
Forward exchange contracts are used in hedging the risks associated with
commitments to purchase securities denominated in foreign currencies for agreed
amounts. The precise matching of forward currency contract amounts and the value
of the securities involved generally will not be possible because the value of
such securities, measured in the foreign currency, will change after the foreign
currency contract has been established. Thus, the Fund might need to purchase or
sell foreign currencies in the spot (cash) market to the extent such foreign
currencies are not covered by forward contracts. The Fund could be exposed to
risk if a counter party is unable to meet the terms of a forward or if the value
of the currency changes unfavorably. The projection of short-term currency
market movements is difficult, and the successful execution of a short-term
hedging strategy is highly uncertain.
 
FEDERAL INCOME TAXES
 
The Trust's policy is to comply with the requirements of the Internal Revenue
Code that are applicable to regulated investment companies and to distribute all
its taxable income to its shareholders. Therefore, no federal income tax
provision is required. To the extent net realized gains are offset through the
application of a capital loss carryover, they will not be distributed to
shareholders but will be retained by the Trust. Each Fund is treated as a
separate taxable entity.
 
As of December 31, 1996, the Government Bond and Money Market Funds had net
capital loss carry forwards in the amounts of $4,334,590 and $6,604,
respectively, The Government Bond Fund carry forward will expire within 6 years
and the Money Market Fund carry forward will expire within 7 to 8 years.
 
The Small Company Fund intends to elect for Federal income tax purposes to treat
approximately $296,817 of net capital losses that arose during the period ended
December 31, 1996, as if such losses arose on January 1, 1997.

ORGANIZATION EXPENSES
 
Initial organization expenses of the Small Company Fund were paid by the advisor
and will be reimbursed by the Fund. Such organization costs have been deferred
and will be amortized ratably over a period of sixty months from the
commencement of operations. If any of the initial shares are redeemed before the
end of the amortization period, the proceeds of the redemption will be reduced
by the pro-rata share of the unamortized organization costs.
 
SECURITY TRANSACTIONS AND INVESTMENT INCOME
 
Security transactions are recorded on the trade date. Dividend income is
recorded on the ex-dividend date or for foreign securities, it is recorded as
soon as the information becomes available. Interest income is recorded on an
accrual basis and includes, where applicable, the pro-rata amortization of
premium or discount.
 
EXPENSES
 
Expenses directly attributed to each Fund are charged to that Fund. Expenses
applicable to all funds in the Trust are allocated based on average net assets.
 
DIVIDENDS TO SHAREHOLDERS
 
A) SMALL COMPANY, CAPITAL APPRECIATION, TOTAL RETURN AND GOVERNMENT BOND
 
  Dividend income is recorded on the ex-dividend date. Dividends from net
  investment income are paid quarterly.
 
B) MONEY MARKET
 
  Dividends from net investment income are declared daily and paid monthly.
 
C) ALL FUNDS
 
  Net realized gains, if any, are declared and distributed at least annually.
 
  Dividends and distributions to shareholders are determined in accordance with
  Federal income tax regulations which may differ from generally accepted
  accounting principles. These "book/tax" differences are considered either
  permanent or temporary in nature. In accordance with AICPA Statement of
  Position 93-2, permanent differences are reclassified within the capital
  accounts based on their nature for Federal income tax purposes; temporary
  differences do not require reclassification. Dividends and distributions that
  exceed net investment income and net realized gains for financial reporting
  purposes, but not for tax purposes, are reported as distributions in excess of
  net investment income and net realized gains. To the extent distributions
  exceed current and accumulated earnings and profits for Federal income tax
  purposes, they are reported as distributions of capital.
 
  Accordingly, the undistributed (distributions in excess of) net investment
  income, distributions in excess of net realized gain and capital have been
  adjusted as of October 31, 1995 and October 31, 1996 by the following amounts:

As investment manager for the Trust, Nationwide Advisory Services, Inc. (NAS),
an affiliated company, earns an annual management fee of .5% based on the
average daily net assets of the Capital Appreciation Fund, Total Return Fund,

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Nationwide Separate Account Trust (Trust) is a diversified, open-end investment
company registered under the Investment Company Act of 1940, as amended. The
Trust offers shares to other open-end investment companies created by Nationwide
Advisory Services, Inc., the Trusts investment advisor, as well as to life
insurance company separate accounts to fund the benefits under variable
insurance or annuity policies issued by life insurance companies. The Trust was
organized as a Massachusetts Trust effective June 30, 1981. To date, only
separate accounts of Nationwide Life Insurance Company and Nationwide Life and
Annuity Insurance Company (formerly Financial Horizons Life Insurance Company),
which are affiliated companies, have purchased shares.
 
The Trust offers shares in five series: Small Company Fund, Capital Appreciation
Fund, Total Return Fund, Government Bond Fund and Money Market Fund. The Trust
was amended in 1995 to create the Small Company Fund. On October 23, 1995, the
Small Company Fund was capitalized through the sale of shares to Nationwide Life
Insurance Company in the amount of $5,000,000, at which time the Small Company
Fund became effective and sales of shares commenced.
 
On January 4, 1997, the Trust's registration statement as to the Nationwide
Separate Account Trust Income Fund's shares became effective. The Fund has not
commenced operations.
 
USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
SECURITY VALUATION
 
A) SMALL COMPANY, CAPITAL APPRECIATION, TOTAL RETURN AND GOVERNMENT BOND
 
  Securities traded on a national securities exchange are valued at the last
  sale price on the principal exchange, or if the securities are traded only in
  the over-the-counter market, they are valued at the last quoted sale price, or
  if there is no sale, at the quoted bid price. Securities for which market
  quotations are not readily available are valued at fair value, using
  procedures authorized by the Board of Trustees. Investments denominated in
  foreign currencies are translated to U.S. dollars at prevailing exchange
  rates. Forward currency exchange contracts are also valued at the prevailing
  exchange rates.
 
  The value of a repurchase agreement generally equals the purchase price paid
  by the Fund (cost) plus the interest accrued to date. The seller, under the
  repurchase agreement, is required to maintain the market value of the
  underlying collateral at not less than the value of the repurchase agreement.
  Securities subject to repurchase agreements are held by the Federal
  Reserve/Treasury book-entry system or by the Fund's custodian or an approved
  sub-custodian.
 
B) MONEY MARKET
 
  Securities are valued at amortized cost, which approximates market value, in
  accordance with Rule 2a-7 of the Investment Company Act of 1940.

                                  (UNAUDITED)
- --------------------------------------------------------------------------------
 
FOREIGN CURRENCY TRANSACTIONS (SMALL COMPANY FUND)
 
Fluctuation in the value of investments resulting from changes in foreign
exchange rates are included with net realized and unrealized gain or loss from
investments.
 
Net realized foreign exchange gains or losses arise from sales of foreign
currencies, currency gains or losses realized on security transactions and the
difference between the amounts of dividends, interest and foreign withholding
taxes recorded on the Fund's books, and the U.S. dollar equivalent of amounts
actually received or paid. Net unrealized foreign exchange gains or losses arise
from changes in the value of assets and liabilities resulting from changes in
exchange rates.
 
The Fund enters into forward currency exchange contracts which are obligations
to purchase or sell a foreign currency at a specified rate on a certain date in
the future. A net realized gain or loss would be incurred if the value of the
contract increases or decreases between the date the contract is opened and the
date it is closed. Forward currency contracts are marked to market daily and
this change in value is reflected in the Statement of Assets and Liabilities as
a net payable for foreign currency contracts purchased and sold.
 
At or before the closing of a forward contract, the Small Company Fund may
either sell a portfolio security and make delivery of the currency, or retain
the security and fully or partially offset its contractual obligation to deliver
the currency by purchasing a second contract. If the Fund retains the portfolio
security and engages in an offsetting transaction, the Fund, at the time of
execution of the offsetting transaction, will incur a gain or loss to the extent
that movement has occurred in forward contract prices.
 
Forward exchange contracts are used in hedging the risks associated with
commitments to purchase securities denominated in foreign currencies for agreed
amounts. The precise matching of forward currency contract amounts and the value
of the securities involved generally will not be possible because the value of
such securities, measured in the foreign currency, will change after the foreign
currency contract has been established. Thus, the Fund might need to purchase or
sell foreign currencies in the spot (cash) market to the extent such foreign
currencies are not covered by forward contracts. The Fund could be exposed to
risk if a counter party is unable to meet the terms of a forward or if the value
of the currency changes unfavorably. The projection of short-term currency
market movements is difficult, and the successful execution of a short-term
hedging strategy is highly uncertain.
 
FEDERAL INCOME TAXES
 
The Trust's policy is to comply with the requirements of the Internal Revenue
Code that are applicable to regulated investment companies and to distribute all
its taxable income to its shareholders. Therefore, no federal income tax
provision is required. To the extent net realized gains are offset through the
application of a capital loss carryover, they will not be distributed to
shareholders but will be retained by the Trust. Each Fund is treated as a
separate taxable entity.
 
As of December 31, 1996, the Government Bond and Money Market Funds had net
capital loss carry forwards in the amounts of $4,334,590 and $6,604,
respectively, The Government Bond Fund carry forward will expire within 6 years
and the Money Market Fund carry forward will expire within 7 to 8 years.
 
The Small Company Fund intends to elect for Federal income tax purposes to treat
approximately $296,817 of net capital losses that arose during the period ended
December 31, 1996 as if such losses arose on January 1, 1997.

ORGANIZATION EXPENSES
 
Initial organization expenses of the Small Company Fund were paid by the advisor
and will be reimbursed by the Fund. Such organization costs have been deferred
and will be amortized ratably over a period of sixty months from the
commencement of operations. If any of the initial shares are redeemed before the
end of the amortization period, the proceeds of the redemption will be reduced
by the pro-rata share of the unamortized organization costs.
 
SECURITY TRANSACTIONS AND INVESTMENT INCOME
 
Security transactions are recorded on the trade date. Dividend income is
recorded on the ex-dividend date or for foreign securities, it is recorded as
soon as the information becomes available. Interest income is recorded on an
accrual basis and includes, where applicable, the pro-rata amortization of
premium or discount.
 
EXPENSES
 
Expenses directly attributed to each Fund are charged to that Fund. Expenses
applicable to all Funds in the Trust are allocated based on average net assets.
 
DIVIDENDS TO SHAREHOLDERS
 
A) SMALL COMPANY, CAPITAL APPRECIATION, TOTAL RETURN AND GOVERNMENT BOND
 
  Dividend income is recorded on the ex-dividend date. Dividends from net
  investment income are paid quarterly.
 
B) MONEY MARKET
 
  Dividends from net investment income are declared daily and paid monthly.
 
C) ALL FUNDS
 
  Net realized gains, if any, are declared and distributed at least annually.
 
  Dividends and distributions to shareholders are determined in accordance with
  Federal income tax regulations which may differ from generally accepted
  accounting principles. These "book/tax" differences are considered either
  permanent or temporary in nature. In accordance with AICPA Statement of
  Position 93-2, permanent differences are reclassified within the capital
  accounts based on their nature for Federal income tax purposes; temporary
  differences do not require reclassification. Dividends and distributions that
  exceed net investment income and net realized gains for financial reporting
  purposes, but not for tax purposes, are reported as distributions in excess of
  net investment income and net realized gains. To the extent distributions
  exceed current and accumulated earnings and profits for Federal income tax
  purposes, they are reported as distributions of capital.

NOTE 2 -- TRANSACTIONS WITH AFFILIATES
 
As investment manager for the Trust, Nationwide Advisory Services, Inc. (NAS),
an affiliated company, earns an annual management fee of .5% based on the
average daily net assets of the Capital Appreciation Fund, Total Return Fund,
Government Bond Fund and Money Market Fund; this fee would not be payable in
full if the effect of such payment would increase total expenses (excluding
taxes other than payroll taxes and brokerage commissions on portfolio
transactions) to an amount exceeding 1% of average daily net assets for any
fiscal year. Such limitations on total expenses did not affect management fees
during the periods covered by the financial statements.
 
As investment manager for the Small Company Fund, NAS earns an annual management
fee of 1.00% of average daily net assets. From such fees pursuant to
sub-investment advisory agreements, NAS pays subadvisory fees to The Dreyfus
Corporation, Neuberger and Berman, L.P., Pictet International Management
Limited, Strong Capital Management, Inc., Van Eck Associates Corporation and
Warburg, Pincus Counsellors, Inc. based on average daily net assets of the
portion of the Small Company Fund under their management. For the six months
ended June 30, 1997, NAS collected $973,505 in fees from the Small Company Fund,
and paid $568,368 in fees to the sub-investment advisors.
 
A subsidiary of NAS (Nationwide Investors Services, Inc.) acts as Transfer and
Dividend Disbursing Agent for the Trust.
 
At a meeting of the Board of Trustees on July 18, 1997, the Board of Trustees
approved the submission of several issues to shareholders of the Funds for
approval at a Special Meeting of Shareholders to be held on September 26, 1997.
These issues included approving a new Investment Advisory Agreement between the
Trust and NAS with respect to the Capital Appreciation Fund, Total Return Fund,
Government Bond Fund, and Money Market Fund, which among others, will change the
fees paid by Shareholders of these Funds. The proposed Investment Advisory
Agreement separates the investment advisory services provided by NAS from the
basic fund administration services that NAS provides. NAS is currently
compensated for these fund administration services under the current investment
advisory agreement. The proposal provides for this compensation under a separate
fund administration agreement (the "Fund Administration Agreement"). Under the
terms of the Fund Administration Agreement, NAS would receive for its services
to each Fund a fee, calculated daily and paid monthly, at an annual rate of
0.05% of each Fund's average daily net assets up to $1 billion and 0.04% on
assets of $1 billion and more.

                        NATIONWIDE SEPARATE ACCOUNT TRUST
                  (REFLECTING AMENDMENTS THROUGH JULY 18, 1997)


                                    ARTICLE I

                                   DEFINITIONS

         The terms "Commission", "Amended Declaration", "Distributor",
"Investment Adviser", "Majority Shareholder Vote", "1940 Act", "Shareholder",
"Shares", "Transfer Agent", "Trust", "Trust Property" and "Trustees" have the
respective meaning given them in the Amended Declaration of Trust of Nationwide
Separate Account Trust adopted August 25, 1983, and as amended from time to
time.

                                   ARTICLE II

                                     OFFICES

         Section 1. Principal Office. Until changed by the Trustees, the
principal office of the Trust in the Commonwealth of Massachusetts shall be in
the City of Boston, County of Suffolk. In addition, the Trust shall maintain
outside the Commonwealth of Massachusetts a principal office at One Nationwide
Plaza, Columbus, Ohio.

         Section 2. Other Offices. The Trust may have offices in such other
places without as well as within the Commonwealth as the Trustees may from time
to time determine.

                                   ARTICLE III

                                  SHAREHOLDERS

         Section 1. Meetings. There is no requirement that the Trustees have
annual meetings of the Shareholders. In the event the Trustees determine to have
an annual meeting of the Shareholders, it shall be held at such place within or
without the Commonwealth of Massachusetts on such day and at such time as the
Trustees shall designate. Special meetings of the Shareholders may be called at
any time by a majority of the Trustees and shall be called by any Trustee upon
written request of Shareholders holding in the aggregate not less than ten
percent (10%) of the outstanding Shares having voting rights, such request
specifying the purpose or purposes for which such meeting is to be called. Any
such meeting shall be held within or without the Commonwealth of Massachusetts
on such day and at such time as the Trustees shall designate.

         Section 2. Notice of Meetings. Notice of all meetings of the
Shareholders, stating the time, place and purpose of the meeting, shall be given
by the Trustees by mail to each Shareholder at his

<PAGE>   3

address as recorded on the register of the Trust, mailed at least ten (10) days
and not more than sixty (60) days before the meeting. Only the business stated
in the notice of the meeting shall be considered at such meeting. No notice need
be given to any Shareholder who shall have failed to inform the Trust of his
current address or if a written waiver of notice, executed before or after the
meeting by the Shareholder or his attorney thereunto authorized, is filed with
the records of the meeting.

         Section 3. Quorum and Required Vote. At any meeting of Shareholders, a
quorum for the transaction of business shall consist of a majority represented
in person or by proxy of all votes attributable to the outstanding Shares
(without regard to individual series) entitled to vote with respect to a matter;
provided, however, that at any meeting at which the only actions to be taken are
actions required by the 1940 Act to be taken by vote of the Shareholders of an
individual series, a quorum shall consist of a majority of all votes
attributable to the outstanding Shares of such individual series entitled to
vote thereon, and that at any meeting at which the only action to be taken shall
have been determined by the Board of Trustees to affect the rights and interests
of one or more but not all series of the Trust, a quorum shall consist of a
majority of all votes attributable to the outstanding Shares of the series so
affected; and provided, further, that reasonable adjournments of such meeting
until a quorum is obtained may be made by a vote attributable so the Shares
present in person or by proxy. A majority of the votes shall decide any question
or a plurality shall elect a Trustee, subject to any applicable requirements of
law or of this Amended Bylaws or the Amended Declaration of Trust; provided,
however, that when any provisions of law or of this Amended Bylaws requires the
holders of Shares of any particular series to vote by series and not in the
aggregate with respect to a matter, then a majority of all votes attributable to
the outstanding Shares of that series shall decide such matter insofar as that
particular series shall be concerned.

         Section 4. Record Date for Meetings. For the purpose of determining the
Shareholders who are entitled to notice of and to vote at any meeting, or to
participate in any distribution, or for the purpose of any other action, the
Trustees may from time to time close the transfer books for such period, not
exceeding thirty (30) days, as the Trustees may determine; or without closing
the transfer books the Trustees may fix a date not more than sixty (60) days
prior to the date of any meeting of Shareholders or distribution or other action
as a record date for the determinations of the persons to be treated as
Shareholders of record for such purposes, except for dividend payments which
shall be governed by the Amended Declaration. Only Shareholders of record at the
close of business on the record date will be entitled to notice of and to vote
at any meeting. At present, the separate accounts of Nationwide Life Insurance
Company and Nationwide Life and Annuity Insurance Company (collectively
"Nationwide") are the only Shareholders of the Trust.

         Section 5. Proxies. At any meeting of Shareholders, any holder of
Shares entitled to vote thereat may vote by proxy, provided that no proxy shall
be voted at any meeting unless it shall have been placed on file with the
Secretary, or with such other officer or agent of the Trust as the Trustees may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of a majority of the Trustees, proxies may be solicited
in the name of one or more Trustees or one or more of the officers of the Trust.
Only Shareholders of record shall be entitled to vote. Each full Share shall be
entitled to one vote and fractional Shares shall be entitled to a vote of such
fraction. When any share is held jointly by several persons, any one of them may
vote at any meeting in person or by proxy in respect of such Share, but if more
than one of them shall be present at such

<PAGE>   4

meeting in person or by proxy, and such joint owners or their proxies so present
disagree as to any vote to be cast, such vote shall not be received in respect
of such Share. A proxy purporting to be executed by or on behalf of a
Shareholder shall be deemed valid unless challenged at or prior to its exercise,
and the burden of proving invalidity shall rest on the challenger. If the holder
of any such Share is a minor or a person of unsound mind, and subject to
guardianship or to the legal control of any other person as regards the change
or management of such Share, he may vote by his guardian or such other person
appointed or having such control, and such vote may be given in person or by
proxy.

         Nationwide will vote the shares of each series at any meeting in
accordance with timely instructions under the variable contracts issued by
Nationwide. Nationwide will vote shares attributable to variable contracts as to
which no voting instructions are received in proportion (for, against or
abstain) to those for which timely instructions are received. If a proxy is
received that does not specify a choice, Nationwide will consider its timely
receipt as an instruction to vote in favor the proposal to which it relates. In
certain circumstances, Nationwide has the right to disregard voting instructions
from certain variable contract owners. Variable contract owners may revoke
previously submitted voting instructions given to Nationwide at any time prior
to any meeting by either submitting to the Trust a subsequently dated proxy,
delivering to the Trust a written notice of revocation or otherwise giving
notice of revocation in open meeting, in all cases prior to the exercise of the
authority granted in the proxy.

         Section 6. Inspection of Records. The records of the Trust shall be
open to inspection by Shareholders to the same extent as is permitted
shareholders of a Massachusetts business corporation or as required by the 1940
Act.

         Section 7. Action with Meeting. Any action which may be taken by
Shareholders may be taken without a meeting if a majority of Shareholders
entitled to vote on the matter (or such larger proportion thereof as shall be
required by law, the Declaration or these Bylaws for approval of such matter)
consent to the action in writing and the written consents are filed with the
records of the meetings of Shareholders. Such consent shall be treated for all
purposes as a vote taken at a meeting of Shareholders.

         Section 1. Meetings of the Trustees. The Trustees may in their
discretion provide for regular or stated meetings of the Trustees. Notice of
regular or stated meetings need not be given. Meetings of the Trustees other
than by regular or stated meetings shall be held whenever called by the
Chairman, or by any one of the Trustees, at the time being in office. Notice of
the time and place of each meeting other than regular or stated meetings shall
be given by the Secretary or an Assistant Secretary or by the officer or Trustee
calling the meeting and shall be mailed to each Trustee at least two days before
the meeting, or shall be telegraphed, cabled, or wirelessed to each Trustee at
his business address, or personally delivered to him at least one day before the
meeting. Such notice may, however, be waived by an Trustee. Notice of a meeting
need not be given to any Trustee if a written waiver of notice, executed by him
before or after the meeting, is filed with the records of the

<PAGE>   5

meeting, or to any Trustee who attends the meeting without protesting prior
thereto or at its commencement the lack of notice to him. A notice or waiver of
notice need not specify the purpose of any meeting. The Trustees may meet by
means of a telephone conference circuit or similar communications equipment by
means of which all persons participating in the meeting can hear each other,
which telephone conference meeting shall be deemed to have been held at a place
designated by the Trustees at the meeting. Participation in a telephone
conference meeting shall constitute presence in person at such meeting. Any
action required or permitted to be taken at any meeting of the Trustees may be
taken by the Trustees without a meeting if all the Trustees consent to the
action in writing and the written consents are filed with the records of the
Trustees' meetings. Such consents shall be treated as a vote for all purposes.

         Section 2. Quorum and Manner of Acting. A majority of the Trustees
shall be present in person at any regular or special meeting of the Trustees in
order to constitute a quorum for the transaction of business at such meeting and
(except as otherwise required by law, the Amended Declaration or these Amended
Bylaws) the act of a majority of the Trustees present at any such meeting, at
which a quorum is present, shall be the act of the Trustees. In the absence of a
quorum, a majority of the Trustees present may adjourn the meeting from time to
time until a quorum shall be present. Notice of an adjourned meeting need not be
given.

                                    ARTICLE V

business of the Trust while the Trustees are not in session, including the

delivered upon redemption of Shares of the Trust, and such other powers of the
Trustees as the Trustees may, from time to time, delegate to them except those
powers which by law, the Amended Declaration or these Amended Bylaws they are
prohibited from delegating. The Trustees may also elect from their own number
other Committees from time to time, the number composing such Committees and
powers conferred upon the same (subject to the same limitations with respect to
the Executive Committee) and the term of membership on such Committees to be
determined by the Trustees. The Trustees may designate a chairman of any such
Committee. In the absence of such designation the Committee may elect its own
Chairman.

         Section 2. Meeting, Quorum and Manner of Acting. The Trustees may (1)
provide for stated meetings of any Committees, (2) specify the manner of calling
and notice required for special meetings of any Committee, (3) specify the
number of members of a Committee required to constitute a quorum and the number
of members of a Committee required to exercise specified powers delegated to
such Committee, (4) authorize the making of decisions to exercise specified
powers by written action of the requisite number of members of a Committee
without a meeting and (5) authorize the members of a Committee to meet by means
of a telephone conference circuit.

records of decisions taken without a meeting and cause them to be recorded in a
book designated for that purpose and kept in the offices of the Trust.

         Section 3. Advisory Board. The Trustees may appoint an Advisory Board
to consist in the first instance of not less than three (3) members. Members of
such Advisory Board shall not be Trustees or officers and need not be
Shareholders. Members of this Board shall hold office for such period as the
Trustees may by resolution provide. Any member of such Board may resign
therefrom by a written instrument signed by him which shall take effect upon
delivery to the Trustees. The Advisory Board shall have no legal powers and
shall not perform the functions of Trustees in any manner, said Board being
intended merely to act in an advisory capacity. Such Advisory Board shall meet
at such times and upon such notice as the Trustees may by resolution provide.

majority of the Trustees. Any officer or agent appointed by any officer or
committee may be removed with or without cause by such appointing officer or
committee.

         Section 4. Powers and Duties of the Chairman. The Chairman may call
meetings of the Trustees and of any Committee thereof when he deems it necessary
and shall preside at all meetings of the Shareholders. Subject to the control of
the Trustees and any Committees of the Trustees, within their respective
spheres, as provided by the Trustees, he shall at all times exercise a general
supervision and direction over the affairs of the Trust. He shall have the power
to employ attorneys and counsel for the Trust and to employ such subordinate
officers, agents, clerks and employees as he may find necessary to transact the
business of the Trust. He shall also have the power to grant, issue, execute or
sign such powers of attorney, proxies or other documents as may be deemed
advisable or necessary in furtherance of the interest of the Trust. The Chairman

render a statement of condition of the finances of the Trust to the Trustees as
often as they shall require the same and he shall in general perform all the
duties incident to the office of Treasurer and such other duties as from time to
time may be assigned to him by the Trustees. The Treasurer shall give a bond for
the faithful discharge of his duties, if required to do so by the Trustees, in

provided for that purpose; he shall have custody of the seal of the Trust; he
shall have charge of the Share transfer books, lists and records unless the same

Bylaws, he shall in general perform all duties incident to the office of
Secretary and such other duties as from time to time may be assigned to him by
the Trustees.

                          INVESTMENT ADVISORY AGREEMENT

         THIS AGREEMENT is made and entered into on this 1st day of November,
1997 between NATIONWIDE SEPARATE ACCOUNT TRUST (the "Trust"), a Massachusetts
business trust, and NATIONWIDE ADVISORY SERVICES, INC. (the "Adviser"), an Ohio
corporation registered under the Investment Advisers Act of 1940 (the "Advisers
Act").


                              W I T N E S S E T H :

         WHEREAS, the Trust is registered with the Securities and Exchange
Commission (the "SEC") as an open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act");

         WHEREAS, the Trust desires to retain the Adviser to furnish certain
investment advisory services, as described herein, with respect to certain of
the series of the Trust, all as now are or may be hereafter listed on Exhibit A
to this Agreement (each, a "Fund"); and

         WHEREAS, the Adviser represents that it is willing and possesses legal
authority to render such services subject to the terms and conditions set forth
in this Agreement.

         NOW, THEREFORE, the Trust and the Adviser do mutually agree and promise
as follows:

         1. Appointment as Adviser. The Trust hereby appoints the Adviser to act
as investment adviser to each Fund subject to the terms and conditions set forth
in this Agreement. The Adviser hereby accepts such appointment and agrees to
furnish the services hereinafter described for the compensation provided for in
this Agreement.

         2.       Duties of Adviser.

                  (a) Investment Management Services. (1) Subject to the
         supervision of the Trust's Board of Trustees (and except as otherwise
         permitted under the terms of any exemptive relief obtained by the
         Adviser from the Securities and Exchange Commission, or by rule or
         regulation), the Adviser will provide, or arrange for the provision of,
         a continuous investment program and overall investment strategies for
         each Fund, including investment research and management with respect to
         all securities and investments and cash equivalents in each Fund. The
         Adviser will determine, or arrange for others to determine, from time
         to time what securities and other investments will be purchased,
         retained or sold by each Fund and will implement, or arrange for others
         to implement, such determinations through the placement, in the name of
         a Fund, of orders for the execution of portfolio transactions with or
         through such brokers or dealers as may be so selected. The Adviser will
         provide, or arrange for the provision of, the services under this
         Agreement in accordance with the stated investment policies and
         restrictions of each Fund as set forth in that Fund's current
         prospectus and statement of additional information as currently in
         effect and as supplemented or amended

<PAGE>   2

         from time to time (collectively referred to hereinafter as the
         "Prospectus") and subject to the directions of the Trust's Board of
         Trustees.

                  (2) Subject to the provisions of this Agreement and the 1940
         Act and any exemptions thereto, the Adviser intends to, and is
         authorized to, appoint one or more qualified subadvisers (each a
         "Subadviser") to provide each Fund with certain services required by
         this Agreement. Each Subadviser shall have such investment discretion
         and shall make all determinations with respect to the investment of a
         Fund's assets as shall be assigned to that Subadviser by the Adviser
         and the purchase and sale of portfolio securities with respect to those
         assets and shall take such steps as may be necessary to implement its
         decisions. The Adviser shall not be responsible or liable for the
         investment merits of any decision by a Subadviser to purchase, hold, or
         sell a security for a Fund.

                  (3) Subject to the supervision and direction of the Trustees,
         the Adviser shall (i) have overall supervisory responsibility for the
         general management and investment of a Fund's assets; (ii) determine
         the allocation of assets among the Subadvisers, if any; and (iii) have
         full investment discretion to make all determinations with respect to
         the investment of Fund assets not otherwise assigned to a Subadviser.

                  (4) The Adviser shall research and evaluate each Subadviser,
         if any, including (i) performing initial due diligence on prospective
         Subadvisers and monitoring each Subadviser's ongoing performance; (ii)
         communicating performance expectations and evaluations to the
         Subadvisers; and (iii) recommending to the Trust's Board of Trustees
         whether a Subadviser's contract should be renewed, modified or
         terminated. The Adviser shall also recommend changes or additions to
         the Subadvisers and shall compensate the Subadvisers.

                  (5) The Adviser shall provide to the Trust's Board of Trustees
         such periodic reports concerning a Fund's business and investments as
         the Board of Trustees shall reasonably request.

                  (b) Compliance with Applicable Laws and Governing Documents.
         In the performance of its duties and obligations under this Agreement,
         the Adviser shall act in conformity with the Trust's Declaration of
         Trust and By-Laws and the Prospectus and with the instructions and
         directions received from the Trustees of the Trust and will conform to
         and comply with the requirements of the 1940 Act, the Internal Revenue
         Code of 1986, as amended (the "Code") (including the requirements for
         qualification as a regulated investment company) and all other
         applicable federal and state laws and regulations.

                  The Adviser acknowledges and agrees that subject to the
         supervision and directions of the Trust's Board of Trustees, it shall
         be solely responsible for compliance with all disclosure requirements
         under all applicable federal and state laws and regulations relating to
         the Trust or a Fund, including, without limitation, the 1940 Act, and
         the rules and regulations

                                        2

<PAGE>   3

         thereunder, except that each Subadviser shall have liability in
         connection with information furnished by the Subadviser to a Fund or to
         the Adviser.

                  (c) Consistent Standards. It is recognized that the Adviser
         will perform various investment management and administrative services
         for entities other than the Trust and the Funds; in connection with
         providing such services, the Adviser agrees to exercise the same skill
         and care in performing its services under this Agreement as the Adviser
         exercises in performing similar services with respect to the other
         fiduciary accounts for which the Adviser has investment
         responsibilities.

                  (d) Brokerage. The Adviser is authorized, subject to the
         supervision of the Trust's Board of Trustees, to establish and maintain
         accounts on behalf of each Fund with, and place orders for the purchase
         and sale of assets not allocated to a Subadviser, with or through, such
         persons, brokers or dealers ("brokers") as Adviser may select and
         negotiate commissions to be paid on such transactions. In the selection
         of such brokers and the placing of such orders, the Adviser shall seek
         to obtain for a Fund the most favorable price and execution available,
         except to the extent it may be permitted to pay higher brokerage
         commissions for brokerage and research services, as provided below. In
         using its reasonable efforts to obtain for a Fund the most favorable
         price and execution available, the Adviser, bearing in mind the Fund's
         best interests at all times, shall consider all factors it deems
         relevant, including price, the size of the transaction, the nature of
         the market for the security, the amount of the commission, if any, the
         timing of the transaction, market prices and trends, the reputation,
         experience and financial stability of the broker involved, and the
         quality of service rendered by the broker in other transactions.
         Subject to such policies as the Trustees may determine, the Adviser
         shall not be deemed to have acted unlawfully or to have breached any
         duty created by this Agreement or otherwise solely by reason of its
         having caused a Fund to pay a broker that provides brokerage and
         research services (within the meaning of Section 28(e) of the
         Securities Exchange Act of 1934) to the Adviser an amount of commission
         for effecting a Fund investment transaction that is in excess of the
         amount of commission that another broker would have charged for
         effecting that transaction if, but only if, the Adviser determines in
         good faith that such commission was reasonable in relation to the value
         of the brokerage and research services provided by such broker or
         dealer, viewed in terms of either that particular transaction or the
         overall responsibilities of the Adviser with respect to the accounts as
         to which it exercises investment discretion.

                  It is recognized that the services provided by such brokers
         may be useful to the Adviser in connection with the Adviser's services
         to other clients. On occasions when the Adviser deems the purchase or
         sale of a security to be in the best interests of a Fund as well as
         other clients of the Adviser, the Adviser, to the extent permitted by
         applicable laws and regulations, may, but shall be under no obligation
         to, aggregate the securities to be sold or purchased in order to obtain
         the most favorable price or lower brokerage commissions and efficient
         execution. In such event, allocation of securities so sold or
         purchased, as well as the expenses incurred in the transaction, will be
         made by the Adviser in the manner the Adviser

                                        3

<PAGE>   4

         considers to be the most equitable and consistent with its fiduciary
         obligations to each Fund and to such other clients.

                  (e) Securities Transactions. The Adviser will not purchase
         securities or other instruments from or sell securities or other
         instruments to a Fund; provided, however, the Adviser may purchase
         securities or other instruments from or sell securities or other
         instruments to a Fund if such transaction is permissible under
         applicable laws and regulations, including, without limitation, the
         1940 Act and the Advisers Act and the rules and regulations promulgated
         thereunder or any exemption therefrom.

                  The Adviser agrees to observe and comply with Rule 17j-1 under
         the 1940 Act and the Trust's Code of Ethics, as the same may be amended
         from time to time.

                  (f) Books and Records. In accordance with the 1940 Act and the
         rules and regulations promulgated thereunder, the Adviser shall
         maintain separate books and detailed records of all matters pertaining
         to the Funds and the Trust (the "Fund's Books and Records"), including,
         without limitation, a daily ledger of such assets and liabilities
         relating thereto and brokerage and other records of all securities
         transactions. The Adviser acknowledges that the Fund's Books and
         Records are property of the Trust. In addition, the Fund's Books and
         Records shall be available to the Trust at any time upon request and
         shall be available for telecopying without delay to the Trust during
         any day that the Funds are open for business.

         3. Expenses. During the term of this Agreement, the Adviser will pay
all expenses incurred by it in connection with its activities under this
Agreement other than the cost of securities, commodities and other investments
(including brokerage commissions and other transaction charges, if any)
purchased for a Fund. The Adviser shall, at its sole expense, employ or
associate itself with such persons as it believes to be particularly fitted to
assist it in the execution of its duties under this Agreement. The Adviser shall
be responsible for the expenses and costs for the officers of the Trust and the
Trustees of Trust who are "interested persons" (as defined in the 1940 Act) of
the Adviser.

         It is understood that the Trust will pay all of its own expenses
including, without limitation, (1) all charges and expenses of any custodian or
depository appointed by the Trust for the safekeeping of its cash, securities
and other assets, (2) all charges and expenses paid to an administrator
appointed by the Trust to provide administrative or compliance services, (3) the
charges and expenses of any transfer agents and registrars appointed by the
Trust, (4) the charges and expenses of independent certified public accountants
and of general ledger accounting and internal reporting services for the Trust,

and of preparing, printing and distributing prospectuses and reports to

         Notwithstanding any other provision of this Agreement, the Adviser may
from time to time agree not to impose all or a portion of its fee otherwise
payable hereunder (in advance of the time such fee or portion thereof would
otherwise accrue). Any such fee reduction may be discontinued or modified by the
Adviser at any time.

         5. Representations and Warranties of Adviser. The Adviser represents

         8.       Duration and Termination.

                  (a) Duration. Unless sooner terminated, this Agreement shall
         continue until October 31, 1999, and thereafter shall continue
         automatically for successive annual periods, provided such continuance
         is specifically approved at least annually by the Trust's Board of
         Trustees or the vote of the lesser of (a) 67% of the shares of a Fund

         50% of the outstanding shares of the Fund; provided that in either
         event its continuance also is approved by a majority of the Trust's
         Trustees who are not "interested persons" (as defined in the 1940 Act)
         of any party to this Agreement, by vote cast in person at a meeting

the Adviser at the same time or at the same price.

         10. Amendment. This Agreement may be amended by mutual consent of the
parties, provided that the terms of each such amendment shall be approved by the

                          INVESTMENT ADVISORY AGREEMENT

         THIS AGREEMENT is made and entered into on this ___ day of September,
1997 between NATIONWIDE SEPARATE ACCOUNT TRUST (the "Trust"), a Massachusetts
business trust, and NATIONWIDE ADVISORY SERVICES, INC. (the "Adviser"), an Ohio
corporation registered under the Investment Advisers Act of 1940 (the "Advisers
Act").


                              W I T N E S S E T H :

         WHEREAS, the Trust is registered with the Securities and Exchange
Commission (the "SEC") as an open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act");

         WHEREAS, the Trust desires to retain the Adviser to furnish certain
investment advisory services, as described herein, with respect to certain of
the series of the Trust, all as now are or may be hereafter listed on Exhibit A
to this Agreement (each, a "Fund"); and

         WHEREAS, the Adviser represents that it is willing and possesses legal
authority to render such services subject to the terms and conditions set forth
in this Agreement.

         NOW, THEREFORE, the Trust and the Adviser do mutually agree and promise
as follows:

         1. Appointment as Adviser. The Trust hereby appoints the Adviser to act
as investment adviser to each Fund subject to the terms and conditions set forth
in this Agreement. The Adviser hereby accepts such appointment and agrees to
furnish the services hereinafter described for the compensation provided for in
this Agreement.

         2. Duties of Adviser.

                  (a) Investment Management Services. (1) Subject to the
         supervision of the Trust's Board of Trustees (and except as otherwise
         permitted under the terms of any exemptive relief obtained by the
         Adviser from the Securities and Exchange Commission, or by rule or
         regulation), the Adviser will provide, or arrange for the provision of,
         a continuous investment program and overall investment strategies for
         each Fund, including investment research and management with respect to
         all securities and investments and cash equivalents in each Fund. The
         Adviser will determine, or arrange for others to determine, from time
         to time what securities and other investments will be purchased,
         retained or sold by each Fund and will implement, or arrange for others
         to implement, such determinations through the placement, in the name of
         a Fund, of orders for the execution of portfolio transactions with or
         through such brokers or dealers as may be so selected. The Adviser will
         provide, or arrange for the provision of, the services under this
         Agreement in accordance with the stated investment policies and
         restrictions of each Fund as set forth in that Fund's current
         prospectus and statement of additional information as currently in
         effect and as supplemented or amended

<PAGE>   2

         from time to time (collectively referred to hereinafter as the
         "Prospectus") and subject to the directions of the Trust's Board of
         Trustees.

                  (2) Subject to the provisions of this Agreement and the 1940
         Act and any exemptions thereto, the Adviser intends to, and is
         authorized to, appoint one or more qualified subadvisers (each a
         "Subadviser") to provide each Fund with certain services required by
         this Agreement. Each Subadviser shall have such investment discretion
         and shall make all determinations with respect to the investment of a
         Fund's assets as shall be assigned to that Subadviser by the Adviser
         and the purchase and sale of portfolio securities with respect to those
         assets and shall take such steps as may be necessary to implement its
         decisions. The Adviser shall not be responsible or liable for the
         investment merits of any decision by a Subadviser to purchase, hold, or
         sell a security for a Fund.

                  (3) Subject to the supervision and direction of the Trustees,
         the Adviser shall (i) have overall supervisory responsibility for the
         general management and investment of a Fund's assets; (ii) determine
         the allocation of assets among the Subadvisers, if any; and (iii) have
         full investment discretion to make all determinations with respect to
         the investment of Fund assets not otherwise assigned to a Subadviser.

                  (4) The Adviser shall research and evaluate each Subadviser,
         if any, including (i) performing initial due diligence on prospective
         Subadvisers and monitoring each Subadviser's ongoing performance; (ii)
         communicating performance expectations and evaluations to the
         Subadvisers; and (iii) recommending to the Trust's Board of Trustees
         whether a Subadviser's contract should be renewed, modified or
         terminated. The Adviser shall also recommend changes or additions to
         the Subadvisers and shall compensate the Subadvisers.

                  (5) The Adviser shall provide to the Trust's Board of Trustees
         such periodic reports concerning a Fund's business and investments as
         the Board of Trustees shall reasonably request.

                  (b) Compliance with Applicable Laws and Governing Documents.
         In the performance of its duties and obligations under this Agreement,
         the Adviser shall act in conformity with the Trust's Declaration of
         Trust and By-Laws and the Prospectus and with the instructions and
         directions received from the Trustees of the Trust and will conform to
         and comply with the requirements of the 1940 Act, the Internal Revenue
         Code of 1986, as amended (the "Code") (including the requirements for
         qualification as a regulated investment company) and all other
         applicable federal and state laws and regulations.

                  The Adviser acknowledges and agrees that subject to the
         supervision and directions of the Trust's Board of Trustees, it shall
         be solely responsible for compliance with all disclosure requirements
         under all applicable federal and state laws and regulations relating to
         the Trust or a Fund, including, without limitation, the 1940 Act, and
         the rules and regulations

                                        2

<PAGE>   3

         thereunder, except that each Subadviser shall have liability in
         connection with information furnished by the Subadviser to a Fund or to
         the Adviser.

                  (c) Consistent Standards. It is recognized that the Adviser
         will perform various investment management and administrative services
         for entities other than the Trust and the Funds; in connection with
         providing such services, the Adviser agrees to exercise the same skill
         and care in performing its services under this Agreement as the Adviser
         exercises in performing similar services with respect to the other
         fiduciary accounts for which the Adviser has investment
         responsibilities.

                  (d) Brokerage. The Adviser is authorized, subject to the
         supervision of the Trust's Board of Trustees, to establish and maintain
         accounts on behalf of each Fund with, and place orders for the purchase
         and sale of assets not allocated to a Subadviser, with or through, such
         persons, brokers or dealers ("brokers") as Adviser may select and
         negotiate commissions to be paid on such transactions. In the selection
         of such brokers and the placing of such orders, the Adviser shall seek
         to obtain for a Fund the most favorable price and execution available,
         except to the extent it may be permitted to pay higher brokerage
         commissions for brokerage and research services, as provided below. In
         using its reasonable efforts to obtain for a Fund the most favorable
         price and execution available, the Adviser, bearing in mind the Fund's
         best interests at all times, shall consider all factors it deems
         relevant, including price, the size of the transaction, the nature of
         the market for the security, the amount of the commission, if any, the
         timing of the transaction, market prices and trends, the reputation,
         experience and financial stability of the broker involved, and the
         quality of service rendered by the broker in other transactions.
         Subject to such policies as the Trustees may determine, the Adviser
         shall not be deemed to have acted unlawfully or to have breached any
         duty created by this Agreement or otherwise solely by reason of its
         having caused a Fund to pay a broker that provides brokerage and
         research services (within the meaning of Section 28(e) of the
         Securities Exchange Act of 1934) to the Adviser an amount of commission
         for effecting a Fund investment transaction that is in excess of the
         amount of commission that another broker would have charged for
         effecting that transaction if, but only if, the Adviser determines in
         good faith that such commission was reasonable in relation to the value
         of the brokerage and research services provided by such broker or
         dealer, viewed in terms of either that particular transaction or the
         overall responsibilities of the Adviser with respect to the accounts as
         to which it exercises investment discretion.

                  It is recognized that the services provided by such brokers
         may be useful to the Adviser in connection with the Adviser's services
         to other clients. On occasions when the Adviser deems the purchase or
         sale of a security to be in the best interests of a Fund as well as
         other clients of the Adviser, the Adviser, to the extent permitted by
         applicable laws and regulations, may, but shall be under no obligation
         to, aggregate the securities to be sold or purchased in order to obtain
         the most favorable price or lower brokerage commissions and efficient
         execution. In such event, allocation of securities so sold or
         purchased, as well as the expenses incurred in the transaction, will be
         made by the Adviser in the manner the Adviser

                                        3

<PAGE>   4

         considers to be the most equitable and consistent with its fiduciary
         obligations to each Fund and to such other clients.

                  (e) Securities Transactions. The Adviser will not purchase
         securities or other instruments from or sell securities or other
         instruments to a Fund; provided, however, the Adviser may purchase
         securities or other instruments from or sell securities or other
         instruments to a Fund if such transaction is permissible under
         applicable laws and regulations, including, without limitation, the
         1940 Act and the Advisers Act and the rules and regulations promulgated
         thereunder or any exemption therefrom.

                  The Adviser agrees to observe and comply with Rule 17j-1 under
         the 1940 Act and the Trust's Code of Ethics, as the same may be amended
         from time to time.

                  (f) Books and Records. In accordance with the 1940 Act and the
         rules and regulations promulgated thereunder, the Adviser shall
         maintain separate books and detailed records of all matters pertaining
         to the Funds and the Trust (the "Fund's Books and Records"), including,
         without limitation, a daily ledger of such assets and liabilities
         relating thereto and brokerage and other records of all securities
         transactions. The Adviser acknowledges that the Fund's Books and
         Records are property of the Trust. In addition, the Fund's Books and
         Records shall be available to the Trust at any time upon request and
         shall be available for telecopying without delay to the Trust during
         any day that the Funds are open for business.

         3. Expenses. During the term of this Agreement, the Adviser will pay
all expenses incurred by it in connection with its activities under this
Agreement other than the cost of securities, commodities and other investments
(including brokerage commissions and other transaction charges, if any)
purchased for a Fund. The Adviser shall, at its sole expense, employ or
associate itself with such persons as it believes to be particularly fitted to
assist it in the execution of its duties under this Agreement. The Adviser shall
be responsible for the expenses and costs for the officers of the Trust and the
Trustees of Trust who are "interested persons" (as defined in the 1940 Act) of
the Adviser.

         It is understood that the Trust will pay all of its own expenses
including, without limitation, (1) all charges and expenses of any custodian or
depository appointed by the Trust for the safekeeping of its cash, securities
and other assets, (2) all charges and expenses paid to an administrator
appointed by the Trust to provide administrative or compliance services, (3) the
charges and expenses of any transfer agents and registrars appointed by the
Trust, (4) the charges and expenses of independent certified public accountants
and of general ledger accounting and internal reporting services for the Trust,
(5) the charges and expenses of dividend and capital gain distributions, (6) the
compensation and expenses of Trustees of the Trust who are not "interested
persons" of the Adviser, (7) brokerage commissions and issue and transfer taxes
chargeable to the Trust in connection with securities transactions to which the
Trust is a party, (8) all taxes and fees payable by the Trust to Federal, State
or other governmental agencies, (9) the cost of stock certificates representing
shares of the Trust, (10) all expenses of shareholders' and Trustees' meetings

                                        4

<PAGE>   5

and of preparing, printing and distributing prospectuses and reports to
shareholders, (11) charges and expenses of legal counsel for the Trust in
connection with legal matters relating to the Trust, including without
limitation, legal services rendered in connection with the Trust's existence,
financial structure and relations with its shareholders, (12) insurance and
bonding premiums, (13) association membership dues, (14) bookkeeping and the
costs of calculating the net asset value of shares of the Trust's Funds, and
(15) expenses relating to the issuance, registration and qualification of the
Trust's shares.

         4. Compensation. For the services provided and the expenses assumed
with respect to a Fund pursuant to this Agreement, the Adviser will be entitled
to the fee listed for each Fund on Exhibit A. Such fees will be computed daily
and payable monthly at an annual rate based on a Fund's average daily net
assets.

         The method of determining net assets of a Fund for purposes hereof
shall be the same as the method of determining net assets for purposes of
establishing the offering and redemption price of the Shares as described in
each Fund's Prospectus. If this Agreement shall be effective for only a portion
of a month, the aforesaid fee shall be prorated for the portion of such month
during which this Agreement is in effect.

         Notwithstanding any other provision of this Agreement, the Adviser may
from time to time agree not to impose all or a portion of its fee otherwise
payable hereunder (in advance of the time such fee or portion thereof would
otherwise accrue). Any such fee reduction may be discontinued or modified by the
Adviser at any time.

         5. Representations and Warranties of Adviser. The Adviser represents

                  (a) The Adviser is registered as an investment adviser under

         the Adviser for the execution, delivery and performance by the Adviser
         of this Agreement, and the execution, delivery and performance by the
         Adviser of this Agreement do not contravene or constitute a default

         of, or connected with, rendering services hereunder or for any losses
         that may be sustained in the purchase, holding or sale of Fund assets;

         continue until __________, 1999, and thereafter shall continue
         automatically for successive annual periods, provided such continuance
         is specifically approved at least annually by the Trust's Board of
         Trustees or the vote of the lesser of (a) 67% of the shares of a Fund
         represented at a meeting if holders of more than 50% of the outstanding
         shares of the Fund are present in person or by proxy or (b) more than
         50% of the outstanding shares of the Fund; provided that in either
         event its continuance also is approved by a majority of the Trust's
         Trustees who are not "interested persons" (as defined in the 1940 Act)
         of any party to this Agreement, by vote cast in person at a meeting

         9. Services Not Exclusive. The services furnished by the Adviser
hereunder are not to be deemed exclusive, and the Adviser shall be free to
furnish similar services to others so long as its services under this Agreement
are not impaired thereby. It is understood that the action taken by the Adviser
under this Agreement may differ from the advice given or the timing or nature of
action taken with respect to other clients of the Adviser, and that a
transaction in a specific security may not be accomplished for all clients of
the Adviser at the same time or at the same price.

         10. Amendment. This Agreement may be amended by mutual consent of the
parties, provided that the terms of each such amendment shall be approved by the

securities of a Fund (as required by the 1940 Act).

         11. Confidentiality. Subject to the duties of the Adviser and the Trust
to comply with applicable law, including any demand of any regulatory or taxing

                          INVESTMENT ADVISORY AGREEMENT

         THIS AGREEMENT is made and entered into on this ___ day of November,
1997 between NATIONWIDE SEPARATE ACCOUNT TRUST (the "Trust"), a Massachusetts
business trust, and NATIONWIDE ADVISORY SERVICES, INC. (the "Adviser"), an Ohio
corporation registered under the Investment Advisers Act of 1940 (the "Advisers
Act").


                              W I T N E S S E T H :

         WHEREAS, the Trust is registered with the Securities and Exchange
Commission (the "SEC") as an open-end management investment company under the
Investment Company Act of 1940 (the "1940 Act");

         WHEREAS, the Trust desires to retain the Adviser to furnish certain
investment advisory services, as described herein, with respect to certain of
the series of the Trust, all as now are or may be hereafter listed on Exhibit A
to this Agreement (each, a "Fund"); and

         WHEREAS, the Adviser represents that it is willing and possesses legal
authority to render such services subject to the terms and conditions set forth
in this Agreement.

         NOW, THEREFORE, the Trust and the Adviser do mutually agree and promise
as follows:

         1. Appointment as Adviser. The Trust hereby appoints the Adviser to act
as investment adviser to each Fund subject to the terms and conditions set forth
in this Agreement. The Adviser hereby accepts such appointment and agrees to
furnish the services hereinafter described for the compensation provided for in
this Agreement.

         2.       Duties of Adviser.

                  (a) Investment Management Services. (1) Subject to the
         supervision of the Trust's Board of Trustees (and except as otherwise
         permitted under the terms of any exemptive relief obtained by the
         Adviser from the Securities and Exchange Commission, or by rule or
         regulation), the Adviser will provide, or arrange for the provision of,
         a continuous investment program and overall investment strategies for
         each Fund, including investment research and management with respect to
         all securities and investments and cash equivalents in each Fund. The
         Adviser will determine, or arrange for others to determine, from time
         to time what securities and other investments will be purchased,
         retained or sold by each Fund and will implement, or arrange for others
         to implement, such determinations through the placement, in the name of
         a Fund, of orders for the execution of portfolio transactions with or
         through such brokers or dealers as may be so selected. The Adviser will
         provide, or arrange for the provision of, the services under this
         Agreement in accordance with the stated investment policies and
         restrictions of each Fund as set forth in that Fund's current
         prospectus and statement of additional information as currently in
         effect and as supplemented or amended

<PAGE>   2

         from time to time (collectively referred to hereinafter as the
         "Prospectus") and subject to the directions of the Trust's Board of
         Trustees.

                  (2) Subject to the provisions of this Agreement and the 1940
         Act and any exemptions thereto, the Adviser intends to, and is
         authorized to, appoint one or more qualified subadvisers (each a
         "Subadviser") to provide each Fund with certain services required by
         this Agreement. Each Subadviser shall have such investment discretion
         and shall make all determinations with respect to the investment of a
         Fund's assets as shall be assigned to that Subadviser by the Adviser
         and the purchase and sale of portfolio securities with respect to those
         assets and shall take such steps as may be necessary to implement its
         decisions. The Adviser shall not be responsible or liable for the
         investment merits of any decision by a Subadviser to purchase, hold, or
         sell a security for a Fund.

                  (3) Subject to the supervision and direction of the Trustees,
         the Adviser shall (i) have overall supervisory responsibility for the
         general management and investment of a Fund's assets; (ii) determine
         the allocation of assets among the Subadvisers, if any; and (iii) have
         full investment discretion to make all determinations with respect to
         the investment of Fund assets not otherwise assigned to a Subadviser.

                  (4) The Adviser shall research and evaluate each Subadviser,
         if any, including (i) performing initial due diligence on prospective
         Subadvisers and monitoring each Subadviser's ongoing performance; (ii)
         communicating performance expectations and evaluations to the
         Subadvisers; and (iii) recommending to the Trust's Board of Trustees
         whether a Subadviser's contract should be renewed, modified or
         terminated. The Adviser shall also recommend changes or additions to
         the Subadvisers and shall compensate the Subadvisers.

                  (5) The Adviser shall provide to the Trust's Board of Trustees
         such periodic reports concerning a Fund's business and investments as
         the Board of Trustees shall reasonably request.

                  (b) Compliance with Applicable Laws and Governing Documents.
         In the performance of its duties and obligations under this Agreement,
         the Adviser shall act in conformity with the Trust's Declaration of
         Trust and By-Laws and the Prospectus and with the instructions and
         directions received from the Trustees of the Trust and will conform to
         and comply with the requirements of the 1940 Act, the Internal Revenue
         Code of 1986, as amended (the "Code") (including the requirements for
         qualification as a regulated investment company) and all other
         applicable federal and state laws and regulations.

                  The Adviser acknowledges and agrees that subject to the
         supervision and directions of the Trust's Board of Trustees, it shall
         be solely responsible for compliance with all disclosure requirements
         under all applicable federal and state laws and regulations relating to
         the Trust or a Fund, including, without limitation, the 1940 Act, and
         the rules and regulations

                                        2

<PAGE>   3

         thereunder, except that each Subadviser shall have liability in
         connection with information furnished by the Subadviser to a Fund or to
         the Adviser.

                  (c) Consistent Standards. It is recognized that the Adviser
         will perform various investment management and administrative services
         for entities other than the Trust and the Funds; in connection with
         providing such services, the Adviser agrees to exercise the same skill
         and care in performing its services under this Agreement as the Adviser
         exercises in performing similar services with respect to the other
         fiduciary accounts for which the Adviser has investment
         responsibilities.

                  (d) Brokerage. The Adviser is authorized, subject to the
         supervision of the Trust's Board of Trustees, to establish and maintain
         accounts on behalf of each Fund with, and place orders for the purchase
         and sale of assets not allocated to a Subadviser, with or through, such
         persons, brokers or dealers ("brokers") as Adviser may select and
         negotiate commissions to be paid on such transactions. In the selection
         of such brokers and the placing of such orders, the Adviser shall seek
         to obtain for a Fund the most favorable price and execution available,
         except to the extent it may be permitted to pay higher brokerage
         commissions for brokerage and research services, as provided below. In
         using its reasonable efforts to obtain for a Fund the most favorable
         price and execution available, the Adviser, bearing in mind the Fund's
         best interests at all times, shall consider all factors it deems
         relevant, including price, the size of the transaction, the nature of
         the market for the security, the amount of the commission, if any, the
         timing of the transaction, market prices and trends, the reputation,
         experience and financial stability of the broker involved, and the
         quality of service rendered by the broker in other transactions.
         Subject to such policies as the Trustees may determine, the Adviser
         shall not be deemed to have acted unlawfully or to have breached any
         duty created by this Agreement or otherwise solely by reason of its
         having caused a Fund to pay a broker that provides brokerage and
         research services (within the meaning of Section 28(e) of the
         Securities Exchange Act of 1934) to the Adviser an amount of commission
         for effecting a Fund investment transaction that is in excess of the
         amount of commission that another broker would have charged for
         effecting that transaction if, but only if, the Adviser determines in
         good faith that such commission was reasonable in relation to the value
         of the brokerage and research services provided by such broker or
         dealer, viewed in terms of either that particular transaction or the
         overall responsibilities of the Adviser with respect to the accounts as
         to which it exercises investment discretion.

                  It is recognized that the services provided by such brokers
         may be useful to the Adviser in connection with the Adviser's services
         to other clients. On occasions when the Adviser deems the purchase or
         sale of a security to be in the best interests of a Fund as well as
         other clients of the Adviser, the Adviser, to the extent permitted by
         applicable laws and regulations, may, but shall be under no obligation
         to, aggregate the securities to be sold or purchased in order to obtain
         the most favorable price or lower brokerage commissions and efficient
         execution. In such event, allocation of securities so sold or
         purchased, as well as the expenses incurred in the transaction, will be
         made by the Adviser in the manner the Adviser

                                        3

<PAGE>   4

         considers to be the most equitable and consistent with its fiduciary
         obligations to each Fund and to such other clients.

                  (e) Securities Transactions. The Adviser will not purchase
         securities or other instruments from or sell securities or other
         instruments to a Fund; provided, however, the Adviser may purchase
         securities or other instruments from or sell securities or other
         instruments to a Fund if such transaction is permissible under
         applicable laws and regulations, including, without limitation, the
         1940 Act and the Advisers Act and the rules and regulations promulgated
         thereunder or any exemption therefrom.

                  The Adviser agrees to observe and comply with Rule 17j-1 under
         the 1940 Act and the Trust's Code of Ethics, as the same may be amended
         from time to time.

                  (f) Books and Records. In accordance with the 1940 Act and the
         rules and regulations promulgated thereunder, the Adviser shall
         maintain separate books and detailed records of all matters pertaining
         to the Funds and the Trust (the "Fund's Books and Records"), including,
         without limitation, a daily ledger of such assets and liabilities
         relating thereto and brokerage and other records of all securities
         transactions. The Adviser acknowledges that the Fund's Books and
         Records are property of the Trust. In addition, the Fund's Books and
         Records shall be available to the Trust at any time upon request and
         shall be available for telecopying without delay to the Trust during
         any day that the Funds are open for business.

         3. Expenses. During the term of this Agreement, the Adviser will pay
all expenses incurred by it in connection with its activities under this
Agreement other than the cost of securities, commodities and other investments
(including brokerage commissions and other transaction charges, if any)
purchased for a Fund. The Adviser shall, at its sole expense, employ or
associate itself with such persons as it believes to be particularly fitted to
assist it in the execution of its duties under this Agreement. The Adviser shall
be responsible for the expenses and costs for the officers of the Trust and the
Trustees of Trust who are "interested persons" (as defined in the 1940 Act) of
the Adviser.

         It is understood that the Trust will pay all of its own expenses
including, without limitation, (1) all charges and expenses of any custodian or
depository appointed by the Trust for the safekeeping of its cash, securities
and other assets, (2) all charges and expenses paid to an administrator
appointed by the Trust to provide administrative or compliance services, (3) the
charges and expenses of any transfer agents and registrars appointed by the
Trust, (4) the charges and expenses of independent certified public accountants
and of general ledger accounting and internal reporting services for the Trust,
(5) the charges and expenses of dividend and capital gain distributions, (6) the
compensation and expenses of Trustees of the Trust who are not "interested
persons" of the Adviser, (7) brokerage commissions and issue and transfer taxes
chargeable to the Trust in connection with securities transactions to which the
Trust is a party, (8) all taxes and fees payable by the Trust to Federal, State
or other governmental agencies, (9) the cost of stock certificates representing
shares of the Trust, (10) all expenses of shareholders' and Trustees' meetings

                                        4

<PAGE>   5

and of preparing, printing and distributing prospectuses and reports to
shareholders, (11) charges and expenses of legal counsel for the Trust in
connection with legal matters relating to the Trust, including without
limitation, legal services rendered in connection with the Trust's existence,
financial structure and relations with its shareholders, (12) insurance and
bonding premiums, (13) association membership dues, (14) bookkeeping and the
costs of calculating the net asset value of shares of the Trust's Funds, and
(15) expenses relating to the issuance, registration and qualification of the
Trust's shares.

         4. Compensation. For the services provided and the expenses assumed
with respect to a Fund pursuant to this Agreement, the Adviser will be entitled
to the fee listed for each Fund on Exhibit A. Such fees will be computed daily
and payable monthly at an annual rate based on a Fund's average daily net
assets.

         The method of determining net assets of a Fund for purposes hereof
shall be the same as the method of determining net assets for purposes of
establishing the offering and redemption price of the Shares as described in
each Fund's Prospectus. If this Agreement shall be effective for only a portion
of a month, the aforesaid fee shall be prorated for the portion of such month
during which this Agreement is in effect.

         Notwithstanding any other provision of this Agreement, the Adviser may
from time to time agree not to impose all or a portion of its fee otherwise
payable hereunder (in advance of the time such fee or portion thereof would
otherwise accrue). Any such fee reduction may be discontinued or modified by the
Adviser at any time.

         5. Representations and Warranties of Adviser. The Adviser represents
and warrants to the Trust as follows:

                  (a) The Adviser is registered as an investment adviser under
         the Advisers Act;

         any governmental body, agency or official is required on the part of
         the Adviser for the execution, delivery and performance by the Adviser
         of this Agreement, and the execution, delivery and performance by the
         Adviser of this Agreement do not contravene or constitute a default

         of its duties hereunder, the Adviser shall not be subject to any
         liability to a Fund or the Trust, for any act or omission in the case
         of, or connected with, rendering services hereunder or for any losses
         that may be sustained in the purchase, holding or sale of Fund assets;

         8. Duration and Termination.

                  (a) Duration. Unless sooner terminated, this Agreement shall
         continue until October 31, 1999, and thereafter shall continue
         automatically for successive annual periods, provided such continuance
         is specifically approved at least annually by the Trust's Board of
         Trustees or the vote of the lesser of (a) 67% of the shares of a Fund
         represented at a meeting if holders of more than 50% of the outstanding
         shares of the Fund are present in person or by proxy or (b) more than
         50% of the outstanding shares of the Fund; provided that in either
         event its continuance also is approved by a majority of the Trust's
         Trustees who are not "interested persons" (as defined in the 1940 Act)
         of any party to this Agreement, by vote cast in person at a meeting
         called for the purpose of voting on such approval.

                  (b) Termination. Notwithstanding whatever may be provided

         voting securities of a Fund, or by the Adviser, in each case, not less
         than sixty (60) days' written notice to the other party.

1940 Act) and shall terminate automatically in the event of its assignment.

         9. Services Not Exclusive. The services furnished by the Adviser
hereunder are not to be deemed exclusive, and the Adviser shall be free to
furnish similar services to others so long as its services under this Agreement
are not impaired thereby. It is understood that the action taken by the Adviser
under this Agreement may differ from the advice given or the timing or nature of
action taken with respect to other clients of the Adviser, and that a
transaction in a specific security may not be accomplished for all clients of
the Adviser at the same time or at the same price.

         10. Amendment. This Agreement may be amended by mutual consent of the
parties, provided that the terms of each such amendment shall be approved by the
Trust's Board of Trustees or by a vote of a majority of the outstanding voting
securities of a Fund (as required by the 1940 Act).

         11. Confidentiality. Subject to the duties of the Adviser and the Trust
to comply with applicable law, including any demand of any regulatory or taxing

                          FUND ADMINISTRATION AGREEMENT

This Fund Administration Agreement is made as of this 1st day of November, 1997,
between Nationwide Separate Account Trust, a Massachusetts business trust (the
"Trust"), and Nationwide Advisory Services, Inc., an Ohio corporation, (the
"Administrator").

WHEREAS, the Trust is a Massachusetts business trust, which operates as an
open-end management investment company and registered under the Investment
Company Act of 1940, as amended (the "Investment Company Act"); and

WHEREAS, the Trust desires to retain the Administrator to provide certain
administrative and fund accounting services described below with respect to
certain of the series of the Trust (the "Funds"), each of which as are now, or
may hereafter be, listed on Exhibit A to this Agreement, and the Administrator
is willing to render such services;

NOW, THEREFORE, in consideration of the premises and mutual covenants set forth
herein, the parties hereto agree as follows:

1.       Appointment of Administrator. The Trust hereby appoints the
         Administrator as administrator of the Funds on the terms and conditions
         set forth in this Agreement; and the Administrator hereby accepts such
         appointment and agrees to perform the services and duties set forth in
         Section 2 of this Agreement in consideration of the compensation
         provided for in Section 4 hereof.

2.       Services and Duties. As Administrator, and subject to the supervision
         and control of the Trust's Board of Trustees, the Administrator will
         provide facilities, equipment, and personnel to carry out the following
         administrative and fund accounting services for operation of the
         business and affairs of the Trust and each of the Funds covered by this
         Agreement:

         a.       prepare, file, and maintain the Trust's governing documents,
                  including the Declaration of Trust, the Bylaws, minutes of
                  meetings of Trustees and shareholders, and proxy statements
                  for meetings of shareholders;

         p.       assist in all aspects of the Funds' operations other than
                  those provided under other specific contracts.

         The foregoing, along with any additional services that the
         Administrator shall agree in writing to perform for the Trust
         hereunder, shall hereafter be referred to as "Administrative Services."
         In compliance with the requirements of Rule 31a-3 under the Investment
         Company Act, the Administrator hereby agrees that all records that it
         maintains for the Trust are the property

<PAGE>   4

         of the Trust and further agrees to surrender promptly to the Trust any
         of such records upon the Trust's request. The Administrator further
         agrees to preserve for the periods prescribed by Investment Company Act
         Rule 31a-2 the records required to be maintained by Investment Company
         Act Rule 31a-1. Administrative Services shall not include any duties,
         functions, or services to be performed for the Trust by the Trust's
         investment adviser, custodian, or transfer agent pursuant to their
         agreements with the Trust.

         The Administrator acknowledges the importance of efficient and prompt
         transmission of information to the life insurance companies affiliated
         with the Administrator ("Nationwide"), the purchaser of Trust shares to
         fund the obligations of certain variable annuity contracts. The
         Administrator agrees to use its best efforts to meet the deadline for
         transmission of pricing information presently set by Nationwide and
         such other time deadlines as may be established from time to time in
         the future.

         When performing Administrative Services to the Trust and for the Funds,
         the Administrator will comply with the provisions of the Declaration of
         Trust and Bylaws of the Trust, will safeguard and promote the welfare
         of the Trust and the Funds, and will comply with the policies that the
         Trustees may from time to time reasonably determine, provided that such
         policies are not in conflict with this Agreement, the Trust's governing
         documents, or any applicable statutes or regulations.

3.       Expenses. The Administrator shall be responsible for expenses incurred
         in providing all the Administrative Services to the Trust, including
         the compensation of the Administrator's employees who serve as officers
         of the Trust, except that the Trust shall reimburse the Administrator
         for the cost of the pricing services that the Administer utilizes. The
         Trust (or the Trust's investment adviser) shall be responsible for all
         other expenses of the Trust, including without limitation: (i)
         investment advisory and subadvisory fees; (ii) interest and taxes;
         (iii) brokerage commissions and other costs in connection with the
         purchase or sale of securities and other investment instruments; (iv)
         fees and expenses of the Trust's trustees, other than those who are
         "interested persons" of the Administrator or investment adviser of the
         Trust; (v) legal and audit expenses; (vi) custodian and transfer and
         dividend disbursing agent fees and expenses; (vii) fees and expenses
         related to the registration and qualification of the Trust and the
         Trust's shares for distribution under state and federal securities
         laws; (viii) expenses of printing and mailing reports and notices and
         proxy material to beneficial shareholders of the Trust; (ix) all other
         expenses incidental to holding meetings of the Trust's shareholders,
         including proxy solicitations therefor; (x) insurance premiums for
         fidelity and other coverage; (xi) association membership dues; (xii)
         such nonrecurring or extraordinary expenses as may arise, including
         those relating to actions, suits or proceedings to which the Trust is a
         party and the legal obligation which the Trust may have to indemnify
         the Trust's trustees and officers with respect thereto.

4.       Compensation. For the Administrative Services provided, the Trust
         hereby agrees to pay and the Administrator hereby agrees to accept as
         full compensation for its services rendered

<PAGE>   5

         hereunder the administrative fee listed for each Fund on Exhibit A.
         Such fees will be computed daily and payable monthly at an annual rate
         based on a Fund's average daily net assets and will be paid monthly as
         soon as practicable after the last day of each month.

         In case of termination of this Agreement during any month, the
         administrative fee for that month shall be reduced proportionately on
         the basis of the number of business days during which it is in effect,
         and the fee computed upon the average net assets for the business days
         it is so in effect for that month.

5.       Responsibility of Administrator.

         a.       The Administrator shall not be liable for any error of
                  judgment or mistake of law or for any loss suffered by the
                  Trust in connection with the matters to which this Agreement
                  relates, except a loss resulting from willful misfeasance, bad
                  faith or negligence on its part in the performance of its
                  duties or from reckless disregard by it of its obligations and
                  duties under this Agreement. Any person, even though also an
                  officer, director, partner, employee or agent of the
                  Administrator, who may be or become an officer or trustee of
                  the Trust, shall be deemed, when rendering services to the
                  Trust or acting on any business of the Trust (other than
                  services or business in connection with the duties of the
                  Administrator hereunder) in accordance with his
                  responsibilities to the Trust as such officer or trustee, to
                  be rendering such services to or acting solely for the Trust
                  and not as an officer, director, partner, employee or agent or
                  one under the control or direction of the Administrator even
                  through paid by the Administrator.

         b.       The Administrator shall be kept indemnified by the Trust and
                  be without liability for any action taken or thing done by it
                  in performing the Administrative Services in accordance with
                  the above standards; provided, however, that the Trust will
                  not indemnify the Administrator for the portion of any loss or
                  claim caused, directly or indirectly, by the negligence,
                  wilfull misfeasance or bad faith of the Administrator or by
                  the Administrator's reckless disregard of its duties and
                  obligations hereunder. In order that the indemnification
                  provisions contained in this Section 5 shall apply, however,
                  it is understood that if in any case the Trust may be asked to
                  indemnify or save the Administrator harmless, the Trust shall
                  be fully and promptly advised of all pertinent facts
                  concerning the situation in question, and it is further
                  understood that the Administrator will use all reasonable care
                  to identify and notify the Trust promptly concerning any
                  situation which presents or appears likely to present the
                  probability of such a claim for indemnification against the
                  Trust. The Trust shall have the option to defend the
                  Administrator against any claim which may be the subject of
                  this indemnification. In the event that the Trust so elects it
                  will so notify the Administrator and thereupon the Trust shall
                  take over complete defense of the claim, and the Administrator
                  shall in such situation initiate no further legal or other
                  expenses for which it shall seek indemnification under this
                  Section. The Administrator shall in

<PAGE>   6

                  no case confess any claim or make any compromise or settlement
                  in any case in which the Trust will be asked to indemnify the
                  Administrator except with the Trust's written consent.

6.       Duration and Termination.

         a.       This Agreement shall become effective as of the date first
                  written above. The Agreement may be terminated at any time,
                  without payment of any penalty, by either party upon 90 days'
                  advance written notice to the other party. The Agreement may
                  also be terminated immediately upon written notice to the
                  other party in the event of a material breach of any provision
                  of this Agreement by such other party.

         b.       Upon the termination of this Agreement, the Trust shall pay to
                  the Administrator such compensation as may be payable prior to
                  the effective date of such termination. In the event that the
                  Trust designates a successor to any of the Administrator's
                  obligations hereunder, the Administrator shall, at the
                  direction of the Trust, transfer to such successor all
                  relevant books, records and other data established or
                  maintained by the Administrator under the foregoing
                  provisions.

7.       Amendment. No provision of this Agreement may be changed, waived,
         discharged or terminated orally, but only by an instrument in writing
         signed by the party against which an enforcement of the change, waiver,
         discharge or termination is sought.

8.       Nationwide Separate Account Trust and its Trustees. The terms
         "Nationwide Separate Account Trust" and the "Trustees of Nationwide
         Separate Account Trust" refer respectively to the Trust created and the
         Trustees, as trustees but not individually or personally, acting from
         time to time under a Declaration of Trust dated as of June 30, 1981, as
         has been or may be amended from time to time, and to which reference is
         hereby made and a copy of which is on file at the office of the
         Secretary of State of The Commonwealth of Massachusetts and elsewhere
         as required by law, and to any and all amendments thereto so filed or
         hereafter filed. The obligations of the Trust entered into in the name
         or on behalf thereof by any of Nationwide Separate Account Trust's
         Trustees, representatives, or agents are not made individually, but
         only in their capacities with respect to Nationwide Separate Account
         Trust. Such obligations are not binding upon any of the Trustees,
         shareholders, or representatives of the Trust personally, but bind only
         the assets of the Trust. All persons dealing with any series of Shares
         of the Trust must look solely to the assets of the Trust belonging to
         such series for the enforcement of any claims against the Trust.

         p.       assist in all aspects of the Funds' operations other than
                  those provided under other specific contracts.

         The foregoing, along with any additional services that the
         Administrator shall agree in writing to perform for the Trust
         hereunder, shall hereafter be referred to as "Administrative Services."
         In compliance with the requirements of Rule 31a-3 under the Investment
         Company Act, the Administrator hereby agrees that all records that it
         maintains for the Trust are the property

<PAGE>   4

         of the Trust and further agrees to surrender promptly to the Trust any
         of such records upon the Trust's request. The Administrator further
         agrees to preserve for the periods prescribed by Investment Company Act
         Rule 31a-2 the records required to be maintained by Investment Company
         Act Rule 31a-1. Administrative Services shall not include any duties,
         functions, or services to be performed for the Trust by the Trust's
         investment adviser, custodian, or transfer agent pursuant to their
         agreements with the Trust.

         The Administrator acknowledges the importance of efficient and prompt
         transmission of information to the life insurance companies affiliated
         with the Administrator ("Nationwide"), the purchaser of Trust shares to
         fund the obligations of certain variable annuity contracts. The
         Administrator agrees to use its best efforts to meet the deadline for
         transmission of pricing information presently set by Nationwide and
         such other time deadlines as may be established from time to time in
         the future.

         When performing Administrative Services to the Trust and for the Funds,
         the Administrator will comply with the provisions of the Declaration of
         Trust and Bylaws of the Trust, will safeguard and promote the welfare
         of the Trust and the Funds, and will comply with the policies that the
         Trustees may from time to time reasonably determine, provided that such
         policies are not in conflict with this Agreement, the Trust's governing
         documents, or any applicable statutes or regulations.

3.       Expenses. The Administrator shall be responsible for expenses incurred
         in providing all the Administrative Services to the Trust, including
         the compensation of the Administrator's employees who serve as officers
         of the Trust, except that the Trust shall reimburse the Administrator
         for the cost of the pricing services that the Administer utilizes. The
         Trust (or the Trust's investment adviser) shall be responsible for all
         other expenses of the Trust, including without limitation: (i)
         investment advisory and subadvisory fees; (ii) interest and taxes;
         (iii) brokerage commissions and other costs in connection with the
         purchase or sale of securities and other investment instruments; (iv)
         fees and expenses of the Trust's trustees, other than those who are
         "interested persons" of the Administrator or investment adviser of the
         Trust; (v) legal and audit expenses; (vi) custodian and transfer and
         dividend disbursing agent fees and expenses; (vii) fees and expenses
         related to the registration and qualification of the Trust and the
         Trust's shares for distribution under state and federal securities
         laws; (viii) expenses of printing and mailing reports and notices and
         proxy material to beneficial shareholders of the Trust; (ix) all other
         expenses incidental to holding meetings of the Trust's shareholders,
         including proxy solicitations therefor; (x) insurance premiums for
         fidelity and other coverage; (xi) association membership dues; (xii)
         such nonrecurring or extraordinary expenses as may arise, including
         those relating to actions, suits or proceedings to which the Trust is a
         party and the legal obligation which the Trust may have to indemnify
         the Trust's trustees and officers with respect thereto.

4.       Compensation. For the Administrative Services provided, the Trust
         hereby agrees to pay and the Administrator hereby agrees to accept as
         full compensation for its services rendered

<PAGE>   5

         hereunder the administrative fee listed for each Fund on Exhibit A.
         Such fees will be computed daily and payable monthly at an annual rate
         based on a Fund's average daily net assets and will be paid monthly as
         soon as practicable after the last day of each month.

         In case of termination of this Agreement during any month, the
         administrative fee for that month shall be reduced proportionately on
         the basis of the number of business days during which it is in effect,
         and the fee computed upon the average net assets for the business days
         it is so in effect for that month.

5.       Responsibility of Administrator.

         a.       The Administrator shall not be liable for any error of
                  judgment or mistake of law or for any loss suffered by the
                  Trust in connection with the matters to which this Agreement
                  relates, except a loss resulting from willful misfeasance, bad
                  faith or negligence on its part in the performance of its
                  duties or from reckless disregard by it of its obligations and
                  duties under this Agreement. Any person, even though also an
                  officer, director, partner, employee or agent of the
                  Administrator, who may be or become an officer or trustee of
                  the Trust, shall be deemed, when rendering services to the
                  Trust or acting on any business of the Trust (other than
                  services or business in connection with the duties of the
                  Administrator hereunder) in accordance with his
                  responsibilities to the Trust as such officer or trustee, to
                  be rendering such services to or acting solely for the Trust
                  and not as an officer, director, partner, employee or agent or
                  one under the control or direction of the Administrator even
                  through paid by the Administrator.

         b.       The Administrator shall be kept indemnified by the Trust and
                  be without liability for any action taken or thing done by it
                  in performing the Administrative Services in accordance with
                  the above standards; provided, however, that the Trust will
                  not indemnify the Administrator for the portion of any loss or
                  claim caused, directly or indirectly, by the negligence,
                  wilfull misfeasance or bad faith of the Administrator or by
                  the Administrator's reckless disregard of its duties and
                  obligations hereunder. In order that the indemnification
                  provisions contained in this Section 5 shall apply, however,
                  it is understood that if in any case the Trust may be asked to
                  indemnify or save the Administrator harmless, the Trust shall
                  be fully and promptly advised of all pertinent facts
                  concerning the situation in question, and it is further
                  understood that the Administrator will use all reasonable care
                  to identify and notify the Trust promptly concerning any
                  situation which presents or appears likely to present the
                  probability of such a claim for indemnification against the
                  Trust. The Trust shall have the option to defend the
                  Administrator against any claim which may be the subject of
                  this indemnification. In the event that the Trust so elects it
                  will so notify the Administrator and thereupon the Trust shall
                  take over complete defense of the claim, and the Administrator
                  shall in such situation initiate no further legal or other
                  expenses for which it shall seek indemnification under this
                  Section. The Administrator shall in

<PAGE>   6

                  no case confess any claim or make any compromise or settlement
                  in any case in which the Trust will be asked to indemnify the
                  Administrator except with the Trust's written consent.

6.       Duration and Termination.

         a.       This Agreement shall become effective as of the date first
                  written above. The Agreement may be terminated at any time,
                  without payment of any penalty, by either party upon 90 days'
                  advance written notice to the other party. The Agreement may
                  also be terminated immediately upon written notice to the
                  other party in the event of a material breach of any provision
                  of this Agreement by such other party.

         b.       Upon the termination of this Agreement, the Trust shall pay to
                  the Administrator such compensation as may be payable prior to
                  the effective date of such termination. In the event that the
                  Trust designates a successor to any of the Administrator's
                  obligations hereunder, the Administrator shall, at the
                  direction of the Trust, transfer to such successor all
                  relevant books, records and other data established or
                  maintained by the Administrator under the foregoing
                  provisions.

7.       Amendment. No provision of this Agreement may be changed, waived,
         discharged or terminated orally, but only by an instrument in writing
         signed by the party against which an enforcement of the change, waiver,
         discharge or termination is sought.

8.       Nationwide Separate Account Trust and its Trustees. The terms
         "Nationwide Separate Account Trust" and the "Trustees of Nationwide
         Separate Account Trust" refer respectively to the Trust created and the
         Trustees, as trustees but not individually or personally, acting from
         time to time under a Declaration of Trust dated as of June 30, 1981, as
         has been or may be amended from time to time, and to which reference is
         hereby made and a copy of which is on file at the office of the
         Secretary of State of The Commonwealth of Massachusetts and elsewhere
         as required by law, and to any and all amendments thereto so filed or
         hereafter filed. The obligations of the Trust entered into in the name
         or on behalf thereof by any of Nationwide Separate Account Trust's
         Trustees, representatives, or agents are not made individually, but
         only in their capacities with respect to Nationwide Separate Account
         Trust. Such obligations are not binding upon any of the Trustees,
         shareholders, or representatives of the Trust personally, but bind only
         the assets of the Trust. All persons dealing with any series of Shares
         of the Trust must look solely to the assets of the Trust belonging to
         such series for the enforcement of any claims against the Trust.

         p.       assist in all aspects of the Funds' operations other than
                  those provided under other specific contracts.

         The foregoing, along with any additional services that the
         Administrator shall agree in writing to perform for the Trust
         hereunder, shall hereafter be referred to as "Administrative Services."
         In compliance with the requirements of Rule 31a-3 under the Investment
         Company Act, the Administrator hereby agrees that all records that it
         maintains for the Trust are the property

<PAGE>   4

         of the Trust and further agrees to surrender promptly to the Trust any
         of such records upon the Trust's request. The Administrator further
         agrees to preserve for the periods prescribed by Investment Company Act
         Rule 31a-2 the records required to be maintained by Investment Company
         Act Rule 31a-1. Administrative Services shall not include any duties,
         functions, or services to be performed for the Trust by the Trust's
         investment adviser, custodian, or transfer agent pursuant to their
         agreements with the Trust.

         The Administrator acknowledges the importance of efficient and prompt
         transmission of information to the life insurance companies affiliated
         with the Administrator ("Nationwide"), the purchaser of Trust shares to
         fund the obligations of certain variable annuity contracts. The
         Administrator agrees to use its best efforts to meet the deadline for
         transmission of pricing information presently set by Nationwide and
         such other time deadlines as may be established from time to time in
         the future.

         When performing Administrative Services to the Trust and for the Funds,
         the Administrator will comply with the provisions of the Declaration of
         Trust and Bylaws of the Trust, will safeguard and promote the welfare
         of the Trust and the Funds, and will comply with the policies that the
         Trustees may from time to time reasonably determine, provided that such
         policies are not in conflict with this Agreement, the Trust's governing
         documents, or any applicable statutes or regulations.

3.       Expenses. The Administrator shall be responsible for expenses incurred
         in providing all the Administrative Services to the Trust, including
         the compensation of the Administrator's employees who serve as officers
         of the Trust, except that the Trust shall reimburse the Administrator
         for the cost of the pricing services that the Administer utilizes. The
         Trust (or the Trust's investment adviser) shall be responsible for all
         other expenses of the Trust, including without limitation: (i)
         investment advisory and subadvisory fees; (ii) interest and taxes;
         (iii) brokerage commissions and other costs in connection with the
         purchase or sale of securities and other investment instruments; (iv)
         fees and expenses of the Trust's trustees, other than those who are
         "interested persons" of the Administrator or investment adviser of the
         Trust; (v) legal and audit expenses; (vi) custodian and transfer and
         dividend disbursing agent fees and expenses; (vii) fees and expenses
         related to the registration and qualification of the Trust and the
         Trust's shares for distribution under state and federal securities
         laws; (viii) expenses of printing and mailing reports and notices and
         proxy material to beneficial shareholders of the Trust; (ix) all other
         expenses incidental to holding meetings of the Trust's shareholders,
         including proxy solicitations therefor; (x) insurance premiums for
         fidelity and other coverage; (xi) association membership dues; (xii)
         such nonrecurring or extraordinary expenses as may arise, including
         those relating to actions, suits or proceedings to which the Trust is a
         party and the legal obligation which the Trust may have to indemnify
         the Trust's trustees and officers with respect thereto.

4.       Compensation. For the Administrative Services provided, the Trust
         hereby agrees to pay and the Administrator hereby agrees to accept as
         full compensation for its services rendered

<PAGE>   5

         hereunder the administrative fee listed for each Fund on Exhibit A.
         Such fees will be computed daily and payable monthly at an annual rate
         based on a Fund's average daily net assets and will be paid monthly as
         soon as practicable after the last day of each month.

         In case of termination of this Agreement during any month, the
         administrative fee for that month shall be reduced proportionately on
         the basis of the number of business days during which it is in effect,
         and the fee computed upon the average net assets for the business days
         it is so in effect for that month.

5.       Responsibility of Administrator.

         a.       The Administrator shall not be liable for any error of
                  judgment or mistake of law or for any loss suffered by the
                  Trust in connection with the matters to which this Agreement
                  relates, except a loss resulting from willful misfeasance, bad
                  faith or negligence on its part in the performance of its
                  duties or from reckless disregard by it of its obligations and
                  duties under this Agreement. Any person, even though also an
                  officer, director, partner, employee or agent of the
                  Administrator, who may be or become an officer or trustee of
                  the Trust, shall be deemed, when rendering services to the
                  Trust or acting on any business of the Trust (other than
                  services or business in connection with the duties of the
                  Administrator hereunder) in accordance with his
                  responsibilities to the Trust as such officer or trustee, to
                  be rendering such services to or acting solely for the Trust
                  and not as an officer, director, partner, employee or agent or
                  one under the control or direction of the Administrator even
                  through paid by the Administrator.

         b.       The Administrator shall be kept indemnified by the Trust and
                  be without liability for any action taken or thing done by it
                  in performing the Administrative Services in accordance with
                  the above standards; provided, however, that the Trust will
                  not indemnify the Administrator for the portion of any loss or
                  claim caused, directly or indirectly, by the negligence,
                  wilfull misfeasance or bad faith of the Administrator or by
                  the Administrator's reckless disregard of its duties and
                  obligations hereunder. In order that the indemnification
                  provisions contained in this Section 5 shall apply, however,
                  it is understood that if in any case the Trust may be asked to
                  indemnify or save the Administrator harmless, the Trust shall
                  be fully and promptly advised of all pertinent facts
                  concerning the situation in question, and it is further
                  understood that the Administrator will use all reasonable care
                  to identify and notify the Trust promptly concerning any
                  situation which presents or appears likely to present the
                  probability of such a claim for indemnification against the
                  Trust. The Trust shall have the option to defend the
                  Administrator against any claim which may be the subject of
                  this indemnification. In the event that the Trust so elects it
                  will so notify the Administrator and thereupon the Trust shall
                  take over complete defense of the claim, and the Administrator
                  shall in such situation initiate no further legal or other
                  expenses for which it shall seek indemnification under this
                  Section. The Administrator shall in

<PAGE>   6

                  no case confess any claim or make any compromise or settlement
                  in any case in which the Trust will be asked to indemnify the
                  Administrator except with the Trust's written consent.

6.       Duration and Termination.

         a.       This Agreement shall become effective as of the date first
                  written above. The Agreement may be terminated at any time,
                  without payment of any penalty, by either party upon 90 days'
                  advance written notice to the other party. The Agreement may
                  also be terminated immediately upon written notice to the
                  other party in the event of a material breach of any provision
                  of this Agreement by such other party.

         b.       Upon the termination of this Agreement, the Trust shall pay to
                  the Administrator such compensation as may be payable prior to
                  the effective date of such termination. In the event that the
                  Trust designates a successor to any of the Administrator's
                  obligations hereunder, the Administrator shall, at the
                  direction of the Trust, transfer to such successor all
                  relevant books, records and other data established or
                  maintained by the Administrator under the foregoing
                  provisions.

7.       Amendment. No provision of this Agreement may be changed, waived,
         discharged or terminated orally, but only by an instrument in writing
         signed by the party against which an enforcement of the change, waiver,

8.       Nationwide Separate Account Trust and its Trustees. The terms
         "Nationwide Separate Account Trust" and the "Trustees of Nationwide
         Separate Account Trust" refer respectively to the Trust created and the
         Trustees, as trustees but not individually or personally, acting from
         time to time under a Declaration of Trust dated as of June 30, 1981, as
         has been or may be amended from time to time, and to which reference is
         hereby made and a copy of which is on file at the office of the
         Secretary of State of The Commonwealth of Massachusetts and elsewhere
         as required by law, and to any and all amendments thereto so filed or
         hereafter filed. The obligations of the Trust entered into in the name
         or on behalf thereof by any of Nationwide Separate Account Trust's
         Trustees, representatives, or agents are not made individually, but
         only in their capacities with respect to Nationwide Separate Account
         Trust. Such obligations are not binding upon any of the Trustees,
         shareholders, or representatives of the Trust personally, but bind only
         the assets of the Trust. All persons dealing with any series of Shares
         of the Trust must look solely to the assets of the Trust belonging to
         such series for the enforcement of any claims against the Trust.

         Administrator shall be in writing and shall be duly given if delivered
