  TOUCHSTONE EMERGING
  GROWTH FUND
 
                                                                               4
 
                        [ICON]TOUCHSTONE FAMILY OF FUNDS
TOUCHSTONE EMERGING GROWTH FUND
 
  The Fund's Investment Goal
 The Emerging Growth Fund seeks to increase the value of Fund shares as a
 primary goal and to earn income as a secondary goal.
 
   
 As with any mutual fund, there is no guarantee that the Fund will achieve its
 goals.
    
  Its Principal Investment Strategies
 
   
 The Fund invests primarily (at least 65% of total assets) in the common stocks
 of smaller, rapidly growing (emerging growth) companies. In selecting its
 investments, the portfolio managers focus on those companies they believe will
 grow faster than the U.S. economy in general. They also choose companies they
 believe are priced lower in the market than their true value.
    
 
 When the portfolio managers believe the following securities offer a good
 potential for capital growth or income, up to 35% of the Fund's assets may be
 invested in:
 
     O Larger company stocks
 
     O Preferred stocks
 
     O Convertible bonds
 
     O Other debt securities, including:
 
   
       collateralized mortgage obligations (CMOs), stripped U.S. government
       securities (Strips) and mortgage-related securities, all of which will
       be rated investment grade
    
 
 The Fund may also invest in:
 
     O Securities of foreign companies traded mainly outside the U.S. (up to
       20%)
 
     O American Depositary Receipts (ADRs) (up to 20%)
 
   
     O Emerging market securities (up to 10%)

The Key Risks
   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    
 
   
     O If the stock market as a whole goes down
    
 
   
     O Because securities of small cap companies may be more thinly traded and
       may have more frequent and larger price changes than securities of larger
       cap companies
    
 
   
     O If the market continually values the stocks in the Fund's portfolio lower
       than the portfolio managers believe they should be valued
    
 
   
     O If the stocks in the Fund's portfolio are not undervalued as expected
    
 
   
     O If the companies in which the Fund invests do not grow as rapidly as
       expected
    
 
   
     O If interest rates go up, causing the value of any debt securities held by
       the Fund to decline
    
 
   
     O Because CMOs, Strips and mortgage-related securities may lose more value
       due to changes in interest rates than other debt securities and are
       subject to prepayment
    
 
   
     O Because investments in foreign securities may have more frequent and
       larger price changes than U.S. securities and may lose value due to
       changes in currency exchange rates and other factors
    
 
   
     O Because emerging market securities involve unique risks, such as exposure
       to economies less diverse and mature than that of the U.S. and economic
       or political changes may cause larger price changes in emerging market
       securities than other foreign securities
    
 
   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.
    
 
   
You can find more information about certain securities in which the Fund may
invest and a more detailed description of risks under the heading Investment
Strategies and Risks later in this Prospectus.
    
 
Who May Want to Invest
 
   
This Fund is most appropriate for you if you are an aggressive investor and are
willing to assume a relatively high amount of risk. You should be comfortable
with extreme levels of volatility, and safety of principal in the short term
should not be a high priority for you. This Fund's approach may be appropriate
for you if you are many years from retirement and are comfortable with wide
market fluctuations.

The Fund's Performance
    
The bar chart shown below indicates the risks of investing in the Emerging
Growth Fund. It shows changes in the performance of the Fund's Class A shares
from year to year since the Fund started. The chart does not reflect any sales
charges. Sales charges will reduce return.
 
   
The Fund's past performance does not necessarily indicate how it will perform in
the future.
    
 
The return for other classes of shares offered by the Fund will differ from the
Class A returns shown in the bar chart, depending on the expenses of that class.

     During the period shown in the Bar Chart, the highest quarterly return
     was 17.69% (for the quarter ended June 30, 1997) and the lowest
     quarterly return was -4.07% (for the quarter ended March 31, 1997).
    
 
   
The table on the following page shows how the Fund's average annual returns for
the periods shown compare to those of the Russell 2000 Index and to the
Wiesenberger Small-Cap-MF. The Russell 2000 Index is a widely recognized
unmanaged index of small cap stock performance. The Wiesenberger Small-Cap-MF is
a composite index of the annual returns of mutual funds that have an investment
style similar to that of the Emerging Growth Fund. The table shows the effect of
the Class A sales charge.

The following example should help you compare the cost of investing in the
Emerging Growth Fund with the cost of investing in other mutual funds. The
example assumes that you invest $10,000 in the Fund for the time periods
indicated and then sell all of your shares at the end of those periods. The
example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                        [ICON]TOUCHSTONE FAMILY OF FUNDS
TOUCHSTONE INTERNATIONAL EQUITY FUND
 
  The Fund's Investment Goal
 The International Equity Fund seeks to increase the value of Fund shares over
 the long-term.
 
   
 As with any mutual fund, there is no guarantee that the Fund will achieve its
 goal.
    
  Its Principal Investment Strategies
 
   
 The Fund invests primarily (at least 80% of total assets) in equity securities
 of foreign companies and will invest in at least three countries outside the
 United States. A large portion of those non-U.S. equity securities may be
 issued by companies active in emerging market countries (up to 40% of total
 assets).
    
 
 The Fund may also invest in certain debt securities issued by U.S. and
 non-U.S. entities (up to 20%), including non-investment grade debt securities
 rated as low as B.
 
   
 The portfolio manager uses a growth oriented style to choose investments for
 the Fund. This includes the use of both qualitative and quantitative analysis
 to identify markets and companies that offer solid growth prospects at
 reasonable prices. The portfolio manager's investment process seeks to add
 value by making good regional and country allocations as well as by selecting
 individual stocks within a region.
    
 
   
The Key Risks
    
 
   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    
 
   
     O If the stock market as a whole goes down
    
 
   
     O Because investments in foreign securities may have more frequent and
       larger price changes than U.S. securities and may lose value due to
       changes in currency exchange rates and other factors
    
 
   
     O Because emerging market securities involve unique risks, such as exposure
       to economies less diverse and mature than that of the U.S. and economic
       or political changes may cause larger price changes in emerging market
       securities than other foreign securities
    
 
   
     O If the stocks in the Fund's portfolio do not grow over the long term as
       expected
    
 
   
     O If interest rates go up, causing the value of any debt securities held by
       the Fund to decline
    
 
   
     O Because issuers of non-investment grade securities held by the Fund are
       more likely to be unable to make timely payments of interest or principal
    
 
   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.
    
 
   
You can find more information about certain securities in which the Fund may
invest and a more detailed description of risks under the heading Investment
Strategies and Risks later in this Prospectus.

Who May Want to Invest
   
This Fund is most appropriate for you if you are an aggressive investor and are
willing to assume a relatively high amount of risk. You should be comfortable
with extreme levels of volatility, and safety of principal in the short term
should not be a high priority for you. This Fund's approach may be appropriate
for you if you are many years from retirement and are comfortable with wide
market fluctuations.
    
 
   
The Fund's Performance
    
 
The bar chart shown below indicates the risks of investing in the International
Equity Fund. It shows changes in the performance of the Fund's Class A shares
from year to year since the Fund started. The chart does not reflect any sales
charges. Sales charges will reduce return.
 
   
The Fund's past performance does not necessarily indicate how it will perform in
the future.
    
 
The return for other classes of shares offered by the Fund will differ from the
Class A returns shown in the bar chart, depending on the expenses of that class.

International Equity Fund with the cost of investing in other mutual funds. The
example assumes that you invest $10,000 in the Fund for the time periods
indicated and then sell all of your shares at the end of those periods. The
example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

  The Fund's Investment Goal
 
 The Income Opportunity Fund seeks to achieve a high level of current income as
 its main goal. The Fund may also seek to increase the value of Fund shares, if
 consistent with its main goal.
 
   
 As with any mutual fund, there is no guarantee that the Fund will achieve its
 goal.
    
  Its Principal Investment Strategies
 
   
 The Fund invests primarily in debt securities.  These debt securities will
 generally be more risky non-investment grade corporate and government
 securities (up to 100%). Non-investment grade debt securities are often
 referred to as "junk bonds" and are considered speculative.
    
 
 The Fund's investments may include:
 
   
     O Securities of foreign companies (up to 100%), but only up to 30% of its
       assets in securities of foreign companies that are denominated in a
       currency other than the U.S. dollar
    
 
   
     O Debt securities that are emerging market securities (up to 65%)
    
 
   
     O Mortgage-related securities, loans and loan participations
    
 
   
     O Currency futures and option contracts
    
 
   
The Key Risks
    
 
   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    
 
   
     O If interest rates go up, causing the value of any debt securities held by
       the Fund to decline
    
 
   
     O Because issuers of non-investment grade securities held by the Fund are
       more likely to be unable to make timely payments of interest or principal
    
 
   
     O Because investments in foreign securities may have more frequent and
       larger price changes than U.S. securities and may lose value due to
       changes in currency exchange rates and other factors
    
 
   
     O Because emerging market securities involve unique risks, such as exposure
       to economies less diverse and mature than that of the U.S. and economic
       or political changes may cause larger price changes in emerging market
       securities than other foreign securities
    
 
   
     O Because mortgage-related securities may lose more value due to changes in
       interest rates than other debt securities and are subject to prepayments
    
 
   
     O Because loans and loan participations may be more difficult to sell than
       other investments and subject to the risk of borrower default
    
 
   
     O If the stock market as a whole goes down

  TOUCHSTONE VALUE PLUS FUND
 
                                                                              18

TOUCHSTONE VALUE PLUS FUND
 
   
  The Fund's Investment Goal
    
 
   
 The Value Plus Fund seeks to increase the value of Fund shares over the
 long-term.
    
 
   
 As with any mutual fund, there is no guarantee that it will achieve its goals.
    
   
  Its Principal Investment Strategies
    
 
   
 The Fund invests primarily (at least 65% of total assets) in common stock of
 larger companies that the portfolio manager believes are undervalued. In
 choosing undervalued stocks, the portfolio manager looks for companies that
 have proven management and unique features or advantages but are believed to
 be priced lower than their true value. These companies may not pay dividends.
 The Fund may also invest in common stocks of rapidly growing companies to
 enhance the Fund's return and vary its investments to avoid having too much of
 the Fund's assets subject to risks specific to undervalued stocks.
    
 
   
 Up to 70% of total assets may be invested in large cap companies and up to 30%
 may be invested in mid cap companies.
    
 
   
 The Fund may invest in:
    
 
   
     O Preferred stocks (up to 35%)
    
 
   
     O Investment grade debt securities
    
 
   
     O Convertible securities
    
 
   
 In addition, the Fund may invest in:
    
 
   
     O Cash equivalent investments (up to 10%)
    
 
   
     O Short-term debt securities
    
 
   
The Key Risks
    
 
   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    
 
   
     O If the stock market as a whole goes down
    
 
   
     O If the market continually values the stocks in the Fund's portfolio lower
       than the portfolio manager believes they should be valued
    
 
   
     O If the stocks in the Fund's portfolio are not undervalued as expected
    
 
   
     O If interest rates go up, causing the value of any debt securities held by
       the Fund to decline
    
 
   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.

Who May Want to Invest
    
 
   
This Fund will be most appealing to you if you are a moderate, or risk tolerant
investor. You should be comfortable with a fair degree of volatility. Capital
appreciation may be important to you, but you may not want to take extreme risks
in order to achieve it. This Fund's approach may be most appropriate for you if
you are many years from retirement and are comfortable with a moderate level of
risk.

                        [ICON]TOUCHSTONE FAMILY OF FUNDS
TOUCHSTONE GROWTH & INCOME FUND
 
  The Fund's Investment Goal
 
 The Growth & Income Fund seeks to increase the value of Fund shares over the
 long-term, while receiving dividend income.
 
   
 As with any mutual fund, there is no guarantee that the Fund will achieve its
 goals.
    
 
  Its Principal Investment Strategies
 
   
 The Fund invests primarily (at least 65% of total assets) in dividend-paying
 common stocks, preferred stocks and convertible securities in a variety of
 industries. The portfolio manager may choose to purchase securities which do
 not pay dividends (up to 35%) but which are expected to increase in value or
 produce high income payments in the future.
    
 
   
 In choosing securities for the Fund, the portfolio manager will follow a value
 oriented style, generally buying securities with yields that are at least 20%
 higher than the average yield of companies in the S&P 500. The portfolio
 manager focuses on investing in companies that have a market capitalization of
 at least $1 billion, but may invest in companies of any size.
    
 
 The Fund may also invest up to 20% of its total assets in debt
 securities -- and within this 20% limitation, the Fund may invest the full 20%
 in investment grade debt securities or up to 5% in non-convertible
 non-investment grade debt securities.
 
 The Fund may also invest in:
 
     O Securities of foreign companies including American Depository Receipts
       (ADRs) (up to 20%)
 
     O Real estate investment trusts (up to 10%)
 
The Key Risks
 
   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    
 
   
     O If the stock market as a whole goes down
    
 
   
     O If any of the stocks in the Fund's portfolio do not increase in value as
       expected
    
 
   
     O If earnings of companies the Fund invests in are not achieved and income
       available for interest or dividend payments is reduced
    
 
   
     O If interest rates go up, causing the value of any debt securities held by
       the Fund to decline
    
 
   
     O Because investments in foreign securities may have more frequent and
       larger price changes than U.S. securities and may lose value due to
       changes in currency exchange rates and other factors
    
 
   
     O Because investments in REITs are more sensitive to changes in interest
       rates and other factors that affect real estate values
    
 
   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.

The Fund's Performance
    
 
   
The bar chart shown below indicates the risks of investing in the Growth &
Income Fund. It shows changes in the performance of the Fund's Class A shares
from year to year since the Fund started. The chart does not reflect any sales
charges. Sales charges will reduce return.
    
 
   
The Fund's past performance does not necessarily indicate how it will perform in
the future.
    
 
   
The return for other classes of shares offered by the Fund will differ from the
Class A returns shown in the bar chart, depending on the expenses of that class.

  The Fund's Investment Goal
 
 The Balanced Fund seeks to achieve both an increase in the value of Fund
 shares and current income.
 
   
 As with any mutual fund, there is no guarantee that the Fund will achieve its
 goals.
    
  Its Principal Investment Strategies
 
   
 The Fund invests in both equity securities (generally about 60% of total
 assets) and debt securities (generally about 40%, but at least 25%). The debt
 securities will be rated investment grade or at the highest level of
 non-investment grade.
    
 
 The Fund may invest in:
 
     O Warrants
 
     O Preferred stocks
 
   
     O Convertible securities
    
 
   
 The Fund may also invest up to one-third of its assets in securities of
 foreign companies, and up to 15% in emerging market securities.
    
 
   
In choosing equity securities for the Fund, the portfolio manager will seek out
companies that are in a strong position within their industry, are owned in part
by management and are selling at a price lower than the company's intrinsic
value. Debt securities are also chosen using a value style. The portfolio
manager will focus on higher yielding securities, but will also consider
expected movements in interest rates and industry position.
    
 
The Key Risks
 
   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    
 
   
     O If the stock market as a whole goes down
    
 
   
     O If the stocks in the Fund's portfolio do not increase in value as
       expected
    
 
   
     O If earnings of companies the Fund invests in are not achieved and income
       available for interest or dividend payments is reduced
    
 
   
     O If interest rates go up, causing the value of any debt securities held by
       the Fund to decline
    
 
   
     O Because investments in foreign securities may have more frequent and
       larger price changes than U.S. securities and may lose value due to
       changes in currency exchange rates and other factors
    
 
   
     O Because emerging market securities involve unique risks, such as exposure
       to economies less diverse and mature than that of the U.S. and economic
       or political changes may cause larger price changes in emerging market
       securities than other foreign securities

The Fund's Performance
    
 
   
The following bar chart indicates the risks of investing in the Balanced Fund.
It shows changes in the performance of the Fund's Class A shares from year to
year since the Fund started. The chart does not reflect any sales charges. Sales
charges will reduce return.
    
 
   
The Fund's past performance does not necessarily indicate how it will perform in
the future.
    
 
The return for other classes of shares offered by the Fund will differ from the
Class A returns shown in the bar chart, depending on the expenses of that class.

The following example should help you compare the cost of investing in the
Balanced Fund with the cost of investing in other mutual funds. The example
assumes that you invest $10,000 in the Fund for the time periods indicated and
then sell all of your shares at the end of those periods. The example also
assumes that your investment has a 5% return each year and that the Fund's
operating expenses remain the same. Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

  The Fund's Investment Goal
 The Bond Fund seeks to provide a high level of current income.
 
   
 As with any mutual fund, there is no guarantee that the Fund will achieve its
 goals.
    
  Its Principal Investment Strategies
 
   
 The Fund invests primarily in higher quality investment grade debt securities
 (at least 65% of total assets). The Fund's investment in debt securities may
 be determined by the direction in which interest rates are expected to move
 because the value of these securities generally moves in the opposite
 direction from interest rates. The Fund expects to have an average maturity
 between five and fifteen years.
    
 
 The Fund invests in:
 
     O Mortgage-related securities
 
     O Asset-backed securities
 
   
     O Preferred stocks
    
 
 The Fund also invests in U.S. or foreign debt securities which are rated
 non-investment grade (up to 35%).
 
 In addition, the Fund may invest in:
 
     O Debt securities denominated in foreign currencies (20% or less)
 
The Key Risks
 
   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    
 
   
     O If interest rates go up, causing the value of any debt securities held by
       the Fund to decline
    
 
   
     O Because investments in foreign securities may have more frequent and
       larger price changes than U.S. securities and may lose value due to
       changes in currency exchange rates and other factors
    
 
   
     O Because issuers of non-investment grade securities held by the Fund are
       more likely to be unable to make timely payments of interest or principal
    
 
   
     O Because mortgage-related securities and asset-backed securities may lose
       more value due to changes in interest rates than other debt securities
       and are subject to prepayment
    
 
   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.

invest and a more detailed description of risks under the heading Investment

    of the Total Annual Fund Operating Expenses of each Class of the Fund (the

The following example should help you compare the cost of investing in the Bond
Fund with the cost of investing in other mutual funds. The example assumes that
you invest $10,000 in the Fund for the time periods indicated and then sell all
of your shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

TOUCHSTONE STANDBY INCOME FUND
 
   
  The Fund's Investment Goal
    
 
   
 The Standby Income Fund seeks to provide a higher level of current income than
 a money market fund, while also seeking to prevent large fluctuations in the
 value of your initial investment. The Fund does not try to keep a constant
 $1.00 per share net asset value.
    
 
   
 As with any mutual fund, there is no guarantee that the Fund will achieve its
 goals.
    
   
  Its Principal Investment Strategies
    
 
   
 The Fund invests mostly in various types of money market instruments. All
 investments will be rated at least investment grade. On average, the
 securities held by the Fund will mature in less than one year.
    
 
   
 The Fund's investments may include:
    
 
   
     O Short-term government securities
    
 
   
     O Mortgage-related securities
    
 
   
     O Asset-backed securities
    
 
   
     O Repurchase agreements
    
 
   
 The Fund may invest up to 50% of total assets in:
    
 
   
     O Securities denominated in U.S. dollars and issued in the U.S. by foreign
       issuers (known as Yankee bonds)
    
 
   
     O Eurodollar Certificates of Deposit
    
 
   
 In addition, the Fund may invest in:
    
 
   
     O Debt securities denominated in foreign currencies (up to 20%)
    
 
   
     O Corporate bonds, commercial paper, certificates of deposit, and bankers'
       acceptances
    
 
   
The Key Risks
    
 
   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    
 
   
     O If interest rates go up, causing the value of any debt securities to
       decline
    
 
   
     O Because mortgage-related securities and asset-backed securities may lose
       more value due to changes in interest rates than other debt securities
       and are subject to prepayment
    
 
   
     O Because investments in foreign securities may have more frequent and
       larger price changes than U.S. securities and may lose value due to
       changes in currency exchange rates and other factors
    
 
   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.

Who May Want to Invest
    
 
   
This Fund is most appropriate for you if you take a relatively low risk approach
to investing. Safety of your investment is of key importance to you.
Additionally, you are willing to accept potentially lower returns in order to
maintain a lower, more tolerable level of risk. This Fund's approach may be most
appropriate for you if you are nearing retirement, or if you have a longer time
horizon, but nevertheless, have a lower risk tolerance. This Fund is also
appropriate for you if you want the added convenience of writing checks directly
from your account.

                        [ICON]TOUCHSTONE FAMILY OF FUNDS
INVESTMENT STRATEGIES AND RISKS
 
Can a Fund depart from its normal strategies?
 
   
Each Fund may depart from its investment strategies by taking temporary
defensive positions in response to adverse market, economic or political
conditions. During these times, a Fund may not achieve its investment goals.
    
 
Do the Funds engage in active trading of securities?
 
   
The International Equity Fund, Income Opportunity Fund and Bond Fund may engage
in active trading to achieve their investment goals. This may cause the Fund to
realize higher capital gains which would be passed on to you. Higher capital
gains could increase your tax liability. Frequent trading also increases
transaction costs, which would lower the Fund's performance.
    
 
   
Can a Fund change its investment goal?
    
 
   
A Fund's investment goal(s) may be changed by a vote of the Board of Trustees
without shareholder approval. You would be notified at least 30 days before any
such change took effect.
    
 
Year 2000 risk
 
Touchstone has implemented steps intended to assure that its major computer
systems and processes are capable of Year 2000 processing. We are also examining
the third parties with whom we work to assess their readiness and are developing
contingency plans to assure that any problems in their systems will not
materially affect Touchstone's operations.
 
   
Companies or governmental entities in which Touchstone Funds invest could also
be affected by the Year 2000 issue, but at this time the Funds cannot predict
the degree of impact.
    
 
   
Computer systems failure of Touchstone, a Fund Sub-Advisor or that of any Fund
service provider could impair Fund services and have a negative impact on a
Fund's operations and returns.

                   EMERGING MARKET SECURITIES.  Emerging Market Securities are
                   issued by a company that:
    
 
   
                        O Is organized under the laws of an emerging market
                          country (any country other than Australia, Austria,

                        O Derives at least 50% of its revenues or profits from
                          operations within emerging market countries or has at
                          least 50% of its assets located in emerging market
                          countries
    
 
   
                   UNDERVALUED STOCKS.  A stock is considered undervalued if the
                   portfolio manager believes it should be trading at a higher
                   price than it is at the time of purchase. Factors considered
                   are:
    
 
   
                        O price relative to earnings
    
 
   
                        O price relative to cash flow
    
 
   
                        O price relative to financial strength
    
 
   
                   REPURCHASE AGREEMENTS.  Repurchase Agreements are
                   collateralized by obligations issued or guaranteed as to both
                   principal and interest by the U.S. Government, its agencies,
                   and instrumentalities. A repurchase agreement is a
                   transaction in which a security is purchased with a
                   simultaneous commitment to sell it back to the seller (a
                   commercial bank or recognized securities dealer) at an agreed
                   upon price on an agreed upon date. This date is usually not
                   more than seven days from the date of purchase. The resale
                   price reflects the purchase price plus an agreed upon market
                   rate of interest, which is unrelated to the coupon rate or
                   maturity of the purchased security.

  INVESTMENT STRATEGIES
  AND RISKS
 
43
 
                        [ICON]TOUCHSTONE FAMILY OF FUNDS
 
Risks of investing in the Funds
 
MARKET RISK.  A Fund that invests in common stocks is subject to stock market
risk. Stock prices in general may decline over short or even extended periods,
regardless of the success or failure of a particular company's operations. Stock
markets tend to run in cycles, with periods when stock prices generally go up
and periods when they generally go down. Common stock prices tend to go up and
down more than those of bonds.
 
   
     O Emerging Growth Companies. Investment in Emerging Growth Companies is
       subject to enhanced risks because such companies generally have limited
       product lines, markets or financial resources and often exhibit a lack of
       management depth. The securities of such companies can be difficult to
       sell and are usually more volatile than securities of larger, more
       established companies.
    
 
   
     O Real Estate Investment Trusts (REITs). Investment in REITs is subject to
       risks similar to those associated with the direct ownership of real
       estate (in addition to securities markets risks). REITs are sensitive to
       factors such as changes in real estate values and property taxes,
       interest rates, cash flow of underlying real estate assets, supply and
       demand, and the management skill and creditworthiness of the issuer.
       REITs may also lose value due to changes in tax or other regulatory
       requirements.
    
 
INTEREST RATE RISK.  A Fund that invests in debt securities is subject to the
risk that the market value of the debt securities will decline because of rising
interest rates. The prices of debt securities are generally linked to the
prevailing market interest rates. In general, when interest rates rise, the
prices of debt securities fall, and when interest rates fall, the prices of debt
securities rise. The price volatility of a debt security also depends on its
maturity. Generally, the longer the maturity of a debt security the greater its
sensitivity to changes in interest rates. To compensate investors for this
higher risk, debt securities with longer maturities generally offer higher
yields than debt securities with shorter maturities.
 
   
     O Mortgage-Related Securities. Payments from the pool of loans underlying a
       Mortgage-Related Security may not be enough to meet the monthly payments
       of the Mortgage-Related Security. If this occurs the Mortgage-Related
       Security will lose value. Also, prepayments of mortgages or mortgage
       foreclosures will shorten the life of the pool of mortgages underlying a
       Mortgage-Related Security and will affect the average life of the
       Mortgage-Related Securities held by a Fund. Mortgage prepayments vary
       based on several factors including the level of interest rates, general
       economic conditions, the location and age of the mortgage and other
       demographic conditions. In periods of falling interest rates, there are
       usually more prepayments. The reinvestment of cash received from
       prepayments will, therefore, usually be at a lower interest rate than the
       original investment, lowering a Fund's yield. Mortgage-Related Securities
       may be less likely to increase in value during periods of falling
       interest rates than other debt securities.

  INVESTMENT STRATEGIES
  AND RISKS
 
                                                                              44
 
                        [ICON]TOUCHSTONE FAMILY OF FUNDS
 
   
CREDIT RISK.  The debt securities in a Fund's portfolio are subject to credit
risk. Credit risk is the possibility that an issuer will fail to make timely
payments of interest or principal. Securities rated in the lowest category of
investment grade securities have some risky characteristics and changes in
economic conditions are more likely to cause issuers of these securities to be
unable to make payments.
    
 
     O Non-Investment Grade Securities. Non-Investment Grade securities are
       sometimes referred to as junk bonds and are very risky with respect to
       their issuers' ability to make payments of interest and principal. There
       is a high risk that a Fund which invests in Non-Investment Grade
       securities could suffer a loss caused by the default of an issuer of such
       securities. Part of the reason for this high risk is that, in the event
       of a default or bankruptcy, holders of Non-Investment Grade securities
       generally will not receive payments until the holders of all other debt
       have been paid. In addition, the market for Non-Investment Grade
       securities has, in the past, had more frequent and larger price changes
       than the markets for other securities. Non-Investment Grade securities
       can also be more difficult to sell for good value.
 
FOREIGN INVESTING.  Investing in foreign securities poses unique risks such as
fluctuation in currency exchange rates, market illiquidity, price volatility,
high trading costs, difficulties in settlement, regulations on stock exchanges,
limits on foreign ownership, less stringent accounting, reporting and disclosure
requirements, and other considerations. In the past, equity and debt instruments
of foreign markets have had more frequent and larger price changes than those of
U.S. markets.
 
     O Emerging Markets Risk.  Investments in a country that is still relatively
       underdeveloped involves exposure to economic structures that are
       generally less diverse and mature than in the U.S. and to political and
       legal systems which may be less stable. In the past, markets of
       developing countries have had more frequent and larger price changes than
       those of developed countries.
 
     O Political Risk. Political risk includes a greater potential for revolts,
       and the taking of assets by governments. For example, a Fund may invest
       in Eastern Europe and former states of the Soviet Union. These countries
       were under communist systems that took control of private industry. This
       could occur again in this region or others in which a Fund may invest, in
       which case the Fund may lose all or part of its investment in that
       country's issuers.

Choosing the Appropriate Funds to Match Your Goals
 
Investing well requires a plan. We recommend that you meet with your financial
advisor to plan a strategy that will best meet your financial goals.
 
You should read this Prospectus carefully and then determine how much you want
to invest. Check below to find the minimum investment amount required for each
Class of shares as well as to learn about the various ways you can purchase your
shares.

Investing in the Funds
 
You can contact your financial advisor to purchase shares of the Funds.
 
You may also purchase shares of any Fund directly from Touchstone. In any event,
you must complete a New Account Application Form. You may obtain account
applications from Touchstone or your financial advisor.
 
   
     O Investor Alert: Touchstone may choose to refuse any purchase order.
    
 
Pricing of Fund Shares
 
   
Each Fund's share price, also called net asset value (NAV), is determined as of
the close of trading (normally 4:00 p.m. Eastern time) every day the New York
Stock Exchange (NYSE) is open. The fund calculates the NAV per share, generally
using market prices, by dividing the total value of each class' net assets by
the number of the class shares outstanding. Shares are purchased at the next
offering price determined after your purchase or sale order is received in
proper form by Touchstone. The offering price is the NAV plus a sales charge, if
applicable.
    
<PAGE>   51
 
  INVESTING WITH TOUCHSTONE
 
                                                                              50
 
                        [ICON]TOUCHSTONE FAMILY OF FUNDS
 
The Fund's investments are valued based on market value or, if no market value
is available, based on fair value as determined by the Board of Trustees (or
under their direction). All assets and liabilities initially expressed in
foreign currency values will be converted into U.S. dollar values. Some specific
pricing strategies follow:
 
     O All short-term dollar-denominated investments that mature in 60 days or
       less are valued on the basis of amortized cost which the Board of
       Trustees has determined represents fair value.
 
     O Securities mainly traded on a U.S. exchange are valued at the last sale
       price on that exchange or, if no sales occurred during the day, at the
       current quoted bid price.
 
   
     O Securities mainly traded on a non-U.S. exchange are generally valued
       according to the preceding closing values on that exchange. However, if
       an event which may change the value of a security occurs after the time
       that the closing value on the non-U.S. exchange was determined, the Board
       of Trustees might decide to value the security based on fair value. This
       may cause the value of the security on the books of the fund to be
       significantly different from the closing value on the non-U.S. exchange
       and may affect the calculation of the NAV.
    
 
   
     O Because portfolio securities that are primarily listed on a non-U.S.
       exchange may trade on weekends or other days when a Fund does not price
       its shares, a Fund's NAV may change on days when shareholders will not be
       able to buy or sell shares.
    
 
Choosing a Class of Shares
 
Each of the Funds (other than the Standby Income Fund) offers Class A shares and
Class C shares. Each class of shares charges different sales charges and
distribution or service fees. The amount of sales charges and other fees you pay
will depend on which class of shares you decide to purchase.
 
Each Fund also offers Class Y shares. Class Y shares are only available for
purchase by pension plans.
 
The Standby Income Fund does not have share classes and it does not charge sales
charges, distribution fees or service fees. The Standby Income Fund may be
purchased by all investors.
 
Class A Shares
 
   
The offering price of each Class A share of a Fund is equal to its NAV plus a
front-end sales charge that you pay when you buy your shares. The front-end
sales charge is generally deducted from the amount of your investment.
    
 
The following tables show the amounts of the front-end sales charge you will pay
on purchases of Class A shares of each Fund as a percentage of (1) offering
price and (2) the net amount invested after the charge has been

amount gets larger.

There is no front-end sales charge if you invest $1 million or more in the
Funds. This includes large total purchases made through programs such as
Aggregation, Concurrent Purchases, Letters of Intent and Rights of Accumulation.
These programs are described more fully in the Statement of Additional
Information (SAI). In addition, there is no front-end sales charge on purchases
by certain persons related to the Fund or its service providers and certain
other persons listed in the Statement of Additional Information.
 
   
If you redeem shares that you purchased as part of the $1 million purchase
within one year, you will pay a contingent deferred sales charge (a sales charge
you pay when you redeem your shares) of 1% on the shares redeemed.

Fund to pay distribution and other fees for the sale and distribution of its
Class A shares and for services provided to holders of Class A shares.
Under the plan, each Fund pays an annual fee of up to 0.25% of the average daily
net assets of the Fund that are attributable to Class A shares. Because these
fees are paid out of the Fund's assets on an ongoing basis, these fees will
increase the cost of your investment.
 
Class C Shares
 
   
The offering price of each Class C share is equal to its NAV. No front-end sales
charge is applied at the time of purchase. All of your investment money goes to
work for you immediately. However, a contingent deferred sales charge of 1% of
the offering price will be charged on shares redeemed within one year after you
purchased them.
    
 
No contingent deferred sales charge is applied if:
 
   
     O The shares which you redeem were acquired through the reinvestment of
       dividends or capital gains distributions.
    
 
   
     O The amount redeemed resulted from increases in the value of the account
       above the amount of the total purchase payments.
    
 
When we determine whether a contingent deferred sales charge is payable on a
redemption, we assume that:
 
   
     O The redemption is made first from amounts free of any contingent deferred
       sales charge; then
    
 
   
     O From the earliest purchase payments(s) that remain invested in the Funds.
    
 
When we determine if amounts are available for redemption free of any contingent
deferred sales charge, we:
 
   
     O Add together all of your original purchase payments;
    
 
   
     O Subtract any amounts previously withdrawn; then
    
 
   
     O Check if there is any remaining amount free of any contingent deferred
       sales charge that can be applied to the total of the current value of the
       shares you have asked to redeem.
    
 
There is no contingent deferred sales charge on purchases by certain persons
related to the Fund or its service providers and certain other parties.
 
   
Each Fund (other than the Standby Income Fund) has adopted a distribution and
service plan under Rule 12b-1 of the 1940 Act for its Class C shares. This plan
allows each Fund to pay distribution and other fees for the sale and
distribution of its Class C shares and for services provided to holders of Class
C shares.
    
 
Under the plan, each Fund pays an annual fee of up to 1.00% of the average daily
net assets of the Fund that are attributable to Class C shares. Because these
fees are paid out of the Fund's assets on an ongoing basis, these fees will
increase the cost of your investment and over time may cost you more than paying
other types of sales charges.

federal funds to Touchstone. Banks may charge a fee for handling wire
transfers. You should contact Touchstone or your financial advisor for
further instructions.
 
MORE INFORMATION ABOUT EXCHANGES: For exchanges from the Standby
Income Fund, which has no sales charge associated with it, the
applicable sales charges on the Fund being purchased will apply. The

by an exchange from a Fund which does have a sales charge or by
reinvestment or cross-reinvestment of dividends or capital gains
distributions.
 
  O SPECIAL TAX CONSIDERATION: For federal income tax purposes, an
    exchange of shares is treated as a sale of the shares and a

O AUTOMATIC INVESTMENT OPTIONS
 
  The various ways that you can invest in the Funds are outlined below.
  Touchstone does not charge any fees for these services.
 
- - AUTOMATIC INVESTMENT PLAN
 
  You can pre-authorize monthly or quarterly investments of $50 or more in each
  Fund to be processed electronically from a checking or savings account. You
  will need to complete the appropriate forms to do this. See the account
  application for further details about this service or call Touchstone at (800)
  669-2796 (PRESS 1).
 
   
- - REINVESTMENT/CROSS REINVESTMENT
    
 
  Dividends and capital gains can be automatically reinvested in the Fund that
  pays them or another Fund within the same class of shares without a fee or
  sales charge. Dividends and capital gains will be reinvested in the Fund that
  pays them, unless you indicate otherwise on your account application. You may
  also choose to have your dividends or capital gains paid to you in cash.
 
   
- - DIRECT DEPOSIT PURCHASE PLAN
    
 
  You may automatically invest Social Security checks, private payroll checks,
  pension payouts or any other pre-authorized government or private recurring
  payments in our Funds. This occurs on a monthly basis and the minimum
  investment is $50.
 
   
- - DOLLAR COST AVERAGING
    
 
  Touchstone's Dollar Cost Averaging program allows you to diversify your
  investments by investing the same amount on a regular basis. You can set up
  periodic automatic transfers of at least $50 from one Touchstone Fund to any
  other. The applicable sales charge, if any, will be assessed.
 
O PROCESSING ORGANIZATIONS
 
   
  You may also purchase shares of the Funds through a "Processing Organization,"
  (e.g. a mutual fund supermarket) which is a broker-dealer, bank or other
  financial institution that purchases shares for its customers. Some of the
  Funds have authorized certain Processing Organizations to receive purchase and
  sales orders on their behalf. Before investing in the Funds through a
  Processing Organization, you should read any materials provided by the
  Processing Organization in conjunction with this Prospectus.
    
<PAGE>   58

                        [ICON]TOUCHSTONE FAMILY OF FUNDS
 
  When shares are purchased this way, there may be various differences. The
  Processing Organization may:
   
     - charge a fee for its services
    
 
   
     - act as the shareholder of record of the shares
    
 
   
     - set different minimum initial and additional investment requirements
    
 
   
     - impose other charges and restrictions
    
 
   
     - designate intermediaries to accept purchase and sales orders on the
       Funds' behalf
    
 
   
  Touchstone considers a purchase or sales order as received when an authorized
  Processing Organization, or its authorized designee, receives the order in
  proper form. These orders will be priced based on the Fund's NAV next computed
  after such order is received in proper form.
    
 
  Shares held through a Processing Organization may be transferred into your
  name following procedures established by your Processing Organization and
  Touchstone. Certain Processing Organizations may receive compensation from the
  Funds, Touchstone, the Advisor or their affiliates.

Selling Your Shares
 
   
You may sell some or all of your Fund shares on any day that the Fund calculates
its NAV. If your request is received in proper form before the close of regular
trading on the NYSE, you will receive a price based on that day's NAV for the
shares you sell. Otherwise, the price you receive will be based on the NAV that
is next calculated.

                        [ICON]TOUCHSTONE FAMILY OF FUNDS
 
SIGNATURE GUARANTEES: Some circumstances require that the request for the sale
of shares have a signature guarantee. A signature guarantee helps protect you
against fraud. You can obtain one from most banks or securities dealers, but not
from a notary public. Some circumstances requiring a signature guarantee
include:
 
   
  - Proceeds from the sale of shares that exceeds $50,000
    
 
   
  - Proceeds to be paid to a person other than the record owner
    
 
   
  - Proceeds to be sent to an address other than the address on the Transfer
    Agent's records
    
 
   
  - Proceeds to be paid to a corporation, partnership, trust or fiduciary
    
 
TELEPHONE SALES:
 
   
If we receive your share sale request before 4:00 p.m. Eastern Time on a day
when the NYSE is open for regular trading, the sale of your shares will be
processed that day. Otherwise it will occur on the next business day.
    
 
Interruptions in telephone service could prevent you from selling your shares in
this manner when you want to. When you have difficulty making telephone sales,
you should mail (or send by overnight delivery) a written request for sale of
your shares to Touchstone.
 
In order to protect your investment assets, Touchstone intends to only follow
instructions received by telephone that it reasonably believes to be genuine.
However, there is no guarantee that the instructions relied upon will always be
genuine and the Trust will not be liable for those cases. The Trust has certain
procedures to confirm that telephone instructions are genuine. If it does not
follow such procedures in a particular case it may be liable for any losses due
to unauthorized or fraudulent instructions. Some of these procedures include:
 
   
  - Requiring personal identification
    
 
   
  - Making checks payable only to the owner(s) of the account shown on the
    Trust's records
    
 
   
  - Mailing checks only to the account address shown on the Trust's records
    
 
   
  - Directing wires only to the bank account shown on the Trust's records
    
 
   
  - Providing written confirmation for transactions requested by telephone
    
 
   
  - Tape recording instructions received by telephone
    
 
O SYSTEMATIC WITHDRAWAL PLAN.  You may elect to receive or send to a third party
  monthly, quarterly or annual withdrawals of $50 or more if your account value
  is at least $5,000. There is no special fee for this service and no minimum
  value is required for retirement plans.
 
O REINSTATEMENT PRIVILEGE.  You may reinvest proceeds from a sale of Fund shares
  or a dividend or capital gain distribution on Fund shares without a sales
  charge in any of the Funds. You may do so by sending a written request and a
  check to Touchstone within 90 days after the date of the sale, dividend or
  distribution. Reinvestment will be at the next NAV calculated after Touchstone
  receives your request.

                        [ICON]TOUCHSTONE FAMILY OF FUNDS
 
  O SPECIAL TAX CONSIDERATION:  If you exercise the Reinstatement Privilege, you
    should contact your tax advisor.
O LOW ACCOUNT BALANCES.  Touchstone may sell your Fund shares if your account
  balance falls below $500 as a result of redemptions that you have made (as
  opposed to a reduction from market changes). This involuntary sale does not
  apply to retirement accounts or custodian accounts under the Uniform Gift to
  Minors Act (UGTMA). Touchstone will let you know that your shares are about to
  be sold and you will have 30 days to increase your account balance to more
  than $500.
 
   
  O SPECIAL CONSIDERATION:  Involuntary sales may result in the sale of your
    Fund shares at a loss or may result in taxable investment gains.
    
 
Receiving Sale Proceeds
 
Touchstone will forward the proceeds of your sale to you (or to your financial
advisor) within seven days.
 
PROCEEDS SENT TO FINANCIAL ADVISORS: Proceeds which are sent to your financial
advisor will not usually be re-invested for you unless you provide specific
instructions to do so. Therefore, the financial advisor may benefit from the use
of your money.
 
FUND SHARES PURCHASED BY CHECK: If you purchase Fund shares by personal check,
the proceeds of a sale of those shares will not be sent to you until the check
has cleared, which may take up to 15 days. If you may need your money more
quickly, you should purchase shares by federal funds, bank wire, or with a
certified or cashier's check.
 
   
It is possible that the payments of your sale proceeds could be postponed or
your right to sell your shares could be suspended during certain circumstances.
These circumstances can occur:
    
 
   
     - when the NYSE is closed for other than customary weekends and holidays
    
 
   
     - when trading on the NYSE is restricted
    
 
   
     - when an emergency situation causes a Fund Sub-Advisor to not be
       reasonably able to dispose of certain securities or to fairly determine
       the value of its net assets
    
 
   
     - during any other time when the SEC, by order, permits it.
    
 
CHECK WRITING -- STANDBY INCOME FUND ONLY: You may establish check writing
privileges from your investment in the Standby Income Fund. To do so, complete
the New Account Application Form and pay the $5 fee per checkbook. You will then
receive checks that you may use to draw against your account. You will be
charged $1 for each check presented for payment.
 
Checks may be payable to anyone you designate in the amount of $500 or more.
Checks must be signed as indicated on your Checking Account Signature Card
contained in the account application. You cannot write a check for an amount
larger than the value of your account (at the time the check is written).
Otherwise your check will be returned. You will continue

                        [ICON]TOUCHSTONE FAMILY OF FUNDS
 
to earn monthly dividends on the funds until the check is presented for payment.
Checks cannot be presented in person to Touchstone. When a check is presented
for payment, Touchstone will sell a sufficient number of shares in your account
to cover the amount of the check. The check writing option can provide you with
easy access to your money, but it is not meant to be used as a regular checking
account.
 
  O SPECIAL TAX CONSIDERATION:  Since the share price of the Standby Income Fund
    may fluctuate daily, use of the check writing privilege can result in sale
    of your shares at a profit or a loss from the time of your purchase. These
    sales of your Fund share may be considered a taxable event.
 
  O INVESTOR ALERT:  You should use the telephone or mail redemption procedures,
    rather than a check, to close your account.
 
  O INVESTOR ALERT:  The check writing privilege may be modified or terminated
    at any time by the Trust or Transfer Agent upon notice to shareholders.

Tax Information
 
   
DISTRIBUTIONS: Each Fund will make distributions that may be taxed as ordinary
income or capital gains (which may be taxed at different rates depending on the
length of time a Fund holds its assets). Each Fund's distributions may be
subject to federal income tax whether you reinvest such dividends in additional
shares of a Fund or choose to receive cash.
    
 
   
ORDINARY INCOME: Income and short-term capital gains that are distributed to you

                         TOUCHSTONE EMERGING GROWTH FUND

THE FUND'S INVESTMENT GOAL

The Emerging Growth Fund seeks to increase the value of Fund shares as a primary
goal and to earn income as a secondary goal.

   
As with any mutual fund, there is no guarantee that the Fund will achieve its 
goals.
    

ITS PRINCIPAL INVESTMENT STRATEGIES

   
The Fund invests primarily (at least 65% of total assets) in the common stocks
of smaller, rapidly growing (emerging growth) companies. In selecting its
investments, the portfolio managers focus on those companies they believe will
grow faster than the U.S. economy in general. They also choose companies they
believe are priced lower in the market than their true value.
    

When the portfolio managers believe the following securities offer a good
potential for capital growth or income, up to 35% of the Fund's assets may be
invested in:

   
         Larger company stocks
         Preferred stocks
         Convertible bonds
         Other debt securities, including:
                  collateralized mortgage obligations (CMOs), stripped U.S. 
                  government securities (Strips) and mortgage-related
                  securities, all of which will be rated investment grade
    

The Fund may also invest in:

         - Securities of foreign companies traded mainly outside the U.S. (up to
         20%) 

         - American Depositary Receipts (ADRs) (up to 20%) 

   
         - Emerging market securities (up to 10%).
    

   
    
                                        4
<PAGE>   75
   
    
THE KEY RISKS

   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    

   
- - If the stock market as a whole goes down.
    

   
    
   
- - Because securities of small cap companies may be more thinly traded and may
  have more frequent and larger price changes than securities of larger cap
  companies.

    
   
- - If the market continually values the stocks in the Fund's portfolio lower than
  the portfolio managers believe they should be valued.
    

   
- - If the stocks in the Fund's portfolio are not undervalued as expected.
    

   
- - If the companies in which the Fund invests do not grow as rapidly as expected.
    

   
- - If interest rates go up, causing the value of any debt securities held by the
  Fund to decline.
    

   
- - Because investments in foreign securities may have more frequent and larger
  price changes than U.S. securities and may lose value due to changes in
  currency exchange rates and other factors.
    

   
- - Because emerging market securities involve unique risks, such as exposure to
  economies less diverse and mature than that of the U.S. and economic or
  political changes may cause larger price changes in emerging market 
  securities than other foreign securities.
    

   
- - Because CMOs, Strips and mortgage-related securities may lose more value due
  to changes in interest rates than other debt securities and are subject to
  prepayment.
    

   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.
    

   
    

   
You can find more information about certain securities in which the Fund may 
invest and a more detailed description of risks under the heading Investment 
Strategies and Risks later in this Prospectus.

WHO MAY WANT TO INVEST

   
This Fund is most appropriate for you if you are an aggressive investor and are
willing to assume a relatively high amount of risk. You should be comfortable
with extreme levels of volatility, and safety of principal in the short term
should not be a high priority for you. This Fund's approach may be appropriate
for you if you are many years from retirement and are comfortable with wide
market fluctuations.

The bar chart shown below indicates the risks of investing in the Emerging
Growth Fund. It shows changes in the performance of the Fund's Class A shares
from year to year since the Fund started. The chart does not reflect any sales
charges. Sales charges will reduce return.

   
The Fund's past performance does not necessarily indicate how it will perform in
the future.
    

The return for other classes of shares offered by the Fund will differ from the
Class A returns shown in the bar chart, depending on the expenses of that class.

</TABLE>
    

   
    

         During the period shown in the Bar Chart, the highest quarterly return
         was 17.69% (for the quarter ended June 30, 1997) and the lowest
         quarterly return was -4.07% (for the quarter ended March 31, 1997).

         (1) The returns shown are for Class A shares. Class A shares are not
         offered in this Prospectus. Class Y shares would have substantially
         similar annual returns because the shares are invested in the same
         portfolio of securities. The annual returns would differ only to the
         extent that the Classes do not have the same expenses.

   
The table below shows how the Fund's average annual returns for the periods
shown compare to those of the Russell 2000 Index and to the Wiesenberger Small
Cap - MF. The Russell 2000 Index is a widely recognized unmanaged index of small
cap stock performance. The Wiesenberger Small Cap - MF is a composite index of
the annual returns of mutual funds that have an investment style similar to that
of the Emerging Growth Fund. The table shows the effect of the Class A sales
charge.

The following example should help you compare the cost of investing in the
Emerging Growth Fund with the cost of investing in other mutual funds. The
example assumes that you invest $10,000 in the Fund for the time periods
indicated and then sell all of your shares at the end of those periods. The
example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                      TOUCHSTONE INTERNATIONAL EQUITY FUND

THE FUND'S INVESTMENT GOAL

The International Equity Fund seeks to increase the value of Fund shares over
the long-term.

   
As with any mutual fund, there is no guarantee that the Fund will achieve its
goal.
    

ITS PRINCIPAL INVESTMENT STRATEGIES

   
The Fund invests primarily (at least 80% of total assets) in equity securities
of foreign companies and will invest in at least three countries outside the
United States. A large portion of those non-U.S. equity securities may be issued
by companies active in emerging market countries (up to 40% of total assets).
    

   
    

The Fund may also invest in certain debt securities issued by U.S. and non-U.S.
entities (up to 20%), including non-investment grade debt securities rated as
low as B.

   
The portfolio manager uses a growth oriented style to choose investments for the
Fund. This includes the use of both qualitative and quantitative analysis to
identify markets and companies that offer solid growth prospects at reasonable
prices. The portfolio manager's investment process seeks to add value by making
good regional and country allocations as well as by selecting individual stocks
within a region.
    

   
    

THE KEY RISKS

   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    

   
- - If the stock market as a whole goes down.
    

   
- - Because investments in foreign securities may have more frequent and larger
  price changes than U.S. securities and may lose value due to changes in
  currency exchange rates and other factors.
    

   
- - Because emerging market securities involve unique risks, such as exposure to
  economies less diverse and mature than that of the U.S. and economic or
  political changes may cause larger price changes in emerging market securities
  than other foreign securities.
    

   
- - If the stocks in the Fund's portfolio do not grow over the long term as
  expected.
    

   
- - If interest rates go up, causing the value of any debt securities held by the
  Fund to decline.
    

   

- - Because issuers of non-investment grade securities held by the Fund are more
  likely to be unable to make timely payments of interest or principal. 
    

   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.
    

   
You can find more information about certain securities in which the Fund may 
invest and a more detailed description of risks under the heading Investment

The following example should help you compare the cost of investing in the
International Equity Fund with the cost of investing in other mutual funds. The
example assumes that you invest $10,000 in the Fund for the time periods
indicated and then sell all of your shares at the end of those periods. The
example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                       TOUCHSTONE INCOME OPPORTUNITY FUND

THE FUND'S INVESTMENT GOAL

The Income Opportunity Fund seeks to achieve a high level of current income as
its main goal. The Fund may also seek to increase the value of Fund shares, if
consistent with its main goal.

   
As with any mutual fund, there is no guarantee that the Fund will achieve its 
goals.
    

ITS PRINCIPAL INVESTMENT STRATEGIES

   
The Fund invests primarily in debt securities. These debt securities will
generally be more risky non-investment grade corporate and government securities
(up to 100%). Non-investment grade debt securities are often referred to as
"junk bonds" and are considered speculative.
    

The Fund's investments may include:

         - Securities of foreign companies (up to 100%), but only up to 30% of
           its assets in securities of foreign companies that are denominated in
           a currency other than the U.S. dollar.

         - Debt securities that are emerging market securities (up to 65%).

   
         - Mortgage-related securities and loans and loan participations.
    

         - Currency futures and option contracts.

   
    
THE KEY RISKS

   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    

   
- - If interest rates go up, causing the value of any debt securities held by the
  Fund to decline.
    

   
    
   
- - Because issuers of non-investment grade securities held by the Fund are more
  likely to be unable to make timely payments of interest or principal.
    

   
- - Because investments in foreign securities may have more frequent and larger
  price changes than U.S. securities and may lose value due to changes in
  currency exchange rates and other factors.
    

   
- - Because emerging market securities involve unique risks, such as exposure to
  economies less diverse and mature than that of the U.S. and economic or
  political changes may cause larger price changes in emerging market securities
  than other foreign securities.
    

   
- - Because mortgage-related securities may lose more value due to changes in
  interest rates than other debt securities and are subject to prepayment. 
    

   
- - Because loans and loan participations may be more difficult to sell than other
  investments and are subject to the risk of borrower default.
    

   
- - If the stock market as a whole goes down.
    

   
An investment in the Fund is not a bank deposit and is not insured or 
guaranteed by the FDIC or by any other government entity.
    

   
You can find more information about certain securities in which the Fund may
invest and a more detailed description of risks under the heading Investment
Strategies and Risks later in this Prospectus.
    

WHO MAY WANT TO INVEST

   
This Fund is most appropriate for you if you are an aggressive investor and are
willing to assume a relatively high amount of risk. You should be comfortable
with extreme levels of volatility, and safety of principal in the short term
should not be a high priority for you. This Fund's approach may be appropriate
for you if you are many years from retirement and are comfortable with wide
market fluctuations.

The bar chart shown below indicates the risks of investing in the Income
Opportunity Fund. It shows changes in the performance of the Fund's Class A
shares from year to year since the Fund started. The chart does not reflect any
sales charges. Sales charges will reduce return.

   
The Fund's past performance does not necessarily indicate how it will perform in
the future.
    

The return for other classes of shares offered by the Fund will differ from the
Class A returns shown in the bar chart, depending on the expenses of that class.

</TABLE>
    
   
    


   
         During the period shown in the Bar Chart, the highest quarterly return
         was 16.15% (for the quarter ended June 30, 1995) and the lowest
         quarterly return was -5.44% (for the quarter ended March 31, 1995).
    

         (1) The returns shown are for Class A shares. Class A shares are not
         offered in this Prospectus. Class Y shares would have substantially
         similar annual returns because the shares are invested in the same
         portfolio of securities. The annual returns would differ only to the
         extent that the Classes do not have the same expenses.

   
The table below shows how the Fund's average annual returns for the periods
shown compare to those of the Lehman Brothers Corporate Bond Index, the
Wiesenberger Corp - High Yield - MF and the Wiesenberger Global Income - MF. The
Lehman Brothers Corporate Bond Index is based on all publicly issued
intermediate fixed-rate, non-convertible investment grade domestic corporate
debt. The Wiesenberger Corp - High Yield - MF index and the Wiesenberger Global
Income - MF index are composite indexes of the annual returns of mutual funds
that have an investment style similar to the Income Opportunity Fund. The table
shows the effect of the Class A sales charge.

                           TOUCHSTONE VALUE PLUS FUND

THE FUND'S INVESTMENT GOAL

The Value Plus Fund seeks to increase the value of Fund shares over the
long-term. 

   
As with any mutual fund, there is no guarantee that the Fund will achieve its 
goals.
    

ITS PRINCIPAL INVESTMENT STRATEGIES

   
The Fund invests primarily (at least 65% of total assets) in common stock of
larger companies that the portfolio manager believes are undervalued. In
choosing undervalued stocks, the portfolio manager looks for companies that have
proven management and unique features or advantages but are believed to be
priced lower than their true value. These companies may not pay dividends. The
Fund may also invest in common stocks of rapidly growing companies to enhance
the Fund's return and vary its investments to avoid having too much of the
Fund's assets subject to risks specific to undervalued stocks.
    

Up to 70% of total assets may be invested in large-cap companies and up to 30%
may be invested in mid-cap companies.

The Fund may invest in:

         - Preferred stocks (up to 35%)

         - Investment grade debt securities

         - Convertible securities.

   
In addition, the Fund may invest in:
    

         - Cash equivalent investments (up to 10%)

         - Short-term debt securities.

   
    

                                       15
<PAGE>   86
   
THE KEY RISKS
    

   
The Fund's share price could fluctuate and you could lose money on your 
investment in the Fund. The Fund could also return less than other investments:
    

   
- - If the stock market as a whole goes down.
    

   
- - If the market continually values the stocks in the Fund's portfolio lower than
  the portfolio manager believes they should be valued.
    

   
- - If the stocks in the Fund's portfolio are not undervalued as expected.
    

   
- - If interest rates go up, causing the value of any debt securities held by the
  Fund to decline.
    

   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.
    

   
You can find more information about certain securities in which the Fund may 
invest and a more detailed description of risks under the heading Investment 
Strategies and Risks later in this Prospectus.
    


WHO MAY WANT TO INVEST
   
This Fund will be most appealing to you if you are a moderate, or risk tolerant
investor. You should be comfortable with a fair degree of volatility. Capital
appreciation may be important to you, but you may not want to take extreme risks
in order to achieve it. This Fund's approach may be most appropriate for you if
you are many years from retirement and are comfortable with a moderate level of
risk.
    


PERFORMANCE NOTE

                         TOUCHSTONE GROWTH & INCOME FUND

THE FUND'S INVESTMENT GOAL

The Growth & Income Fund seeks to increase the value of Fund shares over the
long-term, while receiving dividend income.

   
As with any mutual fund, there is no guarantee that the Fund will achieve its 
goals.
    

ITS PRINCIPAL INVESTMENT STRATEGIES

   
The Fund invests primarily (at least 65% of total assets) in dividend-paying
common stocks, preferred stocks and convertible securities in a variety of
industries. The portfolio manager may choose to purchase securities which do not
pay dividends (up to 35%) but which are expected to increase in value or produce
high income payments in the future.
    

   
In choosing securities for the Fund, the portfolio manager will follow a value
oriented style, generally buying securities with yields that are at least 20%
higher than the average yield of companies in the S&P 500. The portfolio manager
focuses on investing in companies that have a market capitalization of at least
$1 billion, but may invest in companies of any size.
    

The Fund may also invest up to 20% of its total assets in debt securities - and
within this 20% limitation, the Fund may invest the full 20% in investment grade
debt securities or up to 5% in non-convertible non-investment grade debt
securities.

The Fund may also invest in:

         - Securities of foreign companies including American Depository
           Receipts (ADRs) (up to 20%).

         - Real estate investment trusts (up to 10%).

   
    

THE KEY RISKS

   
The fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments: 
    

   
- - If the stock market as a whole goes down.
    

   
- - If any of the stocks in the Fund's portfolio do not increase in value as
  expected.
    

   
- - If earnings of companies the Fund invests in are not achieved and income
  available for interest or dividend payments is reduced.
    

   
- - If interest rates go up, causing the value of any debt securities held by the
  Fund to decline.
    

   
- - Because investments in foreign securities may have more frequent and larger
  price changes than U.S. securities and may lose value due to changes in
  currency exchange rates and other factors.
    

   
- - Because investments in REITs are more sensitive to changes in interest rates
  and other factors that affect real estate values.
    

   
An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the FDIC or any other government entity.

WHO MAY WANT TO INVEST
   
This Fund will be most appealing to you if you are a moderate or risk tolerant
investor. You should be comfortable with a fair degree of volatility. Capital
appreciation of your investment capital may be important to you, however, you 
may be uncomfortable taking extreme risk in order to achieve it. This Fund's 
approach may be most appropriate for you if you are many years from retirement
and are comfortable with a moderate level of risk.

The bar chart shown below indicates the risks of investing in the Growth &
Income Fund. It shows changes in the performance of the Fund's Class A shares
from year to year since the Fund started. The chart does not reflect any sales
charges. Sales charges will reduce return.

   
The Fund's past performance does not necessarily indicate how it will perform in
the future.
    

The return for other classes of shares offered by the Fund will differ from the
Class A returns shown in the bar chart, depending on the expenses of that class.

         During the period shown in the bar chart, the highest quarterly return
         was 11.77% (for the quarter ended June 30, 1997) and the lowest
         quarterly return was -4.35% (for the quarter ended March 31, 1997).

         (1) The returns shown are for Class A shares. Class A shares are not
         offered in this Prospectus. Class Y shares would have substantially
         similar annual returns because the shares are invested in the same
         portfolio of securities. The annual returns would differ only to the
         extent that the Classes do not have the same expenses.

   
The table below shows how the Fund's average annual returns for the periods
shown compare to those of the S&P 500 Index and to the Wiesenberger Growth &

example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses remain the same. Although your actual costs may be
higher or lower, based on these assumptions your costs would be:

                            TOUCHSTONE BALANCED FUND

THE FUND'S INVESTMENT GOAL

The Balanced Fund seeks to achieve both an increase in the value of Fund shares
and current income.

   
As with any mutual fund, there is no guarantee that the Fund will achieve its 
goals.
    

   
    

ITS PRINCIPAL INVESTMENT STRATEGIES

   
The Fund invests in both equity securities (generally about 60% of total assets)
and debt securities (generally about 40%, but at least 25%). The debt securities
will be rated investment grade or at the highest level of non-investment grade.
    

The Fund may invest in:

         - Warrants

         - Preferred stocks

         - Convertible securities.

   
The Fund may also invest up to one-third of its assets in securities of foreign
companies, and up to 15% in emerging market securities.
    

   
In choosing equity securities for the Fund, the portfolio manager will seek out
companies that are in a strong position within their industry, are owned in part
by management and are selling at a price lower than the company's intrinsic
value. Debt securities are also chosen using a value style. The portfolio
manager will focus on higher yielding securities, but will also consider
expected movements in interest rates and industry position.
    

THE KEY RISKS

   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    

   
- - If the stock market as a whole goes down.
    

   
    

   
- - If the stocks in the Fund's portfolio do not increase in value as expected.
    

   
- - If earnings of companies the Fund invests in are not achieved and income
  available for interest or dividend payments is reduced.
    

   
    

   
- - If interest rates go up, causing the value of any debt securities held by the
  Fund to decline.
    

   
- - Because investments in foreign securities may have more frequent and larger
  price changes than U.S. securities and may lose value due to changes in
  currency exchange rates and other factors.
    

   
- - Because emerging market securities involve unique risks, such as exposure to
  economies less diverse and mature than that of the U.S. and economic or
  political changes may cause larger price changes in emerging market securities
  than other foreign securities.
    

   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.
    

   
You can find more information about certain securities in which the Fund may
invest and a more detailed description of risks under the heading Investment
Strategies and Risks later in this Prospectus.
    

WHO MAY WANT TO INVEST

   
This Fund is most appropriate for you if you are a risk neutral or moderately
conservative investor. You may typically take a relatively low risk approach to
investing and may be comfortable with a low level of volatility in your
investments. While safety may be important to you, you may also value
appreciation of your investments. If you invest in this Fund, you should be
willing to accept some risk. This Fund's approach may be appropriate for you if
you are several years from retirement.

         quarterly return was -0.32% (for the quarter ended March 31, 1997).

         (1) The returns shown are for Class A shares. Class A shares are not

The table below shows how the Fund's average annual returns for the periods
shown compare to those of the Standard & Poor's Composite Index of 500 Stocks,
the Lehman Brothers Government/Corporate Index and to the Wiesenberger Balanced
Domestic - MF index. The Lehman Brothers Government/Corporate Index is composed
of 5,400 publicly issued corporate and U.S. government debt rated Baa or better
with at least one year to maturity and at least $25 million par outstanding. The
Wiesenberger Balanced Domestic - MF index is a composite index of the annual
returns of mutual funds that have an investment style similar to the Balanced
Fund. The table shows the effect of the Class A sales charge.

                              TOUCHSTONE BOND FUND

THE FUND'S INVESTMENT GOAL

The Bond Fund seeks to provide a high level of current income.

   
As with any mutual fund, there is no guarantee that the Fund will achieve its 
goals.
    

   
    

ITS PRINCIPAL INVESTMENT STRATEGIES

   
The Fund invests primarily in higher quality investment grade debt securities
(at least 65% of total assets). The Fund's investment in debt securities may be
determined by the direction in which interest rates are expected to move because
the value of these securities generally moves in the opposite direction from
interest rates. The Fund expects to have an average maturity between five and
fifteen years.
    

The Fund invests in:

         - Mortgage-related securities

         - Asset-backed securities

         - Preferred stocks.

The Fund also invests in U.S. or foreign debt securities which are rated
non-investment grade (up to 35%).

In addition, the Fund may invest in :

         - Debt securities denominated in foreign currencies (20% or less)

   
    
THE KEY RISKS

   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    

   
- - If interest rates go up, causing the value of any debt securities held by the
  Fund to decline.
    

   
- - Because investments in foreign securities may have more frequent and larger
  price changes than U.S. securities and may lose value due to changes in
  currency exchange rates and other factors.
    

   
- - Because issuers of non-investment grade securities held by the Fund are more
  likely to be unable to make timely payments of interest or principal.
    

   
- - Because mortgage-related securities and asset-backed securities may lose more
  value due to changes in interest rates than other debt securities and are
  subject to prepayment.
    

   
An investment in the Fund is not a bank deposit and is not insured or guaranteed
by the FDIC or any other government entity.
    

   
You can find more information about certain securities in which the Fund may 
invest and a more detailed description of risks under the heading Investment 
Strategies and Risks later in this Prospectus.
    

WHO MAY WANT TO INVEST

This Fund is most appropriate for you if you prefer to take a relatively low
risk approach to investing. Safety of your investment may be the most important
factor to you. You may be willing to accept potentially lower returns in order
to maintain a lower, more tolerable level of risk. This Fund's approach may be
most appropriate for you if you are nearing retirement.

         During the period shown in the bar chart, the highest quarterly return
         was 5.21% (for the quarter ended December 31, 1997) and the lowest
         quarterly return was -2.10% (for the quarter ended March 31, 1997).

         (1) The returns shown are for Class A shares. Class A shares are not
         offered in this Prospectus. Class Y shares would have substantially
         similar annual returns because the shares are invested in the same
         portfolio of securities. The annual returns would differ only to the
         extent that the Classes do not have the same expenses.


   
The table below shows how the Fund's average annual returns for the periods
shown compare to those of the Lehman Brothers Aggregate Index and to the
Wiesenberger Corp - Investment Grade - MF index. The Lehman Brothers Aggregate
Index is comprised of approximately 6000 publicly traded bonds with an average
maturity of about 10 years. The Wiesenberger Corp - Investment Grade - MF index
is a composite index of the annual returns of mutual funds that have an
investment style similar to the Bond Fund. The table shows the effect of the
Class A sales charge.

The following example should help you compare the cost of investing in the Bond
Fund with the cost of investing in other mutual funds. The example assumes that
you invest $10,000 in the Fund for the time periods indicated and then sell all
of your shares at the end of those periods. The example also assumes that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

                         TOUCHSTONE STANDBY INCOME FUND

THE FUND'S INVESTMENT GOAL

   
The Standby Income Fund seeks to provide a higher level of current income than a
money market fund, while also seeking to prevent large fluctuations in the value
of your initial investment. The Fund does not try to keep a constant $1.00 per
share net asset value.
    

   
As with any mutual fund, there is no guarantee that the Fund will achieve its
goals.
    


ITS PRINCIPAL INVESTMENT STRATEGIES

The Fund invests mostly in various types of money market instruments. All
investments will be rated at least investment grade. On average, the securities
held by the Fund will mature in less than one year.

   
The Fund's investments may include:
    

          - Short-term government securities

          - Mortgage-related securities

          - Asset-backed securities

          - Repurchase agreements.

   
The Fund may invest up to 50% of total assets in:
    

          - Securities denominated in U.S. dollars and issued in the U.S. by
            foreign issuers (known as Yankee bonds),

          - Eurodollar Certificates of Deposit.

   
In addition, the Fund may invest in:
    

          - Debt securities denominated in foreign currencies (up to 20%).

          - Corporate bonds, commercial paper, certificates of deposit, and
            bankers' acceptances.

   
    

THE KEY RISKS

   
The Fund's share price will fluctuate and you could lose money on your
investment in the Fund. The Fund could also return less than other investments:
    

   
- - If interest rates go up, causing the value of any debt securities to decline.
    


   
- - Because mortgage-related securities and asset-backed securities may lose more
  value due to changes in interest rates than other debt securities and are
  subject to prepayment.
    

   
- - Because investments in foreign securities may have more frequent and larger
  price changes than U.S. securities and may lose value due to changes in
  currency exchange rates and other factors.
    

   
An investment in the Fund is not a bank deposit and is not insured or
guaranteed by the FDIC or any other government entity.
    

   
You can find more information about certain securities in which the Fund may 
invest and a more detailed description of risks under the heading Investment 
Strategies and Risks later in this Prospectus.
    

WHO MAY WANT TO INVEST

This Fund is most appropriate for you if you take a relatively low risk approach
to investing. Safety of your investment is of key importance to you.
Additionally, you are willing to accept potentially lower returns in order to
maintain a lower, more tolerable level of risk. This Fund's approach may be most
appropriate for you if you are nearing retirement, or if you have a longer time
horizon, but nevertheless, have a lower risk tolerance. This Fund is also
appropriate for you if you want the added convenience of writing checks directly
from your account.

         During the period shown in the bar chart, the highest quarterly return
         was 1.57% (for the quarter ended December 31, 1995) and the lowest
         quarterly return was 1.07% (for the quarter ended March 31, 1996).

         (1) The returns shown are for Class A shares. Class A shares are not
         offered in this Prospectus. Class Y shares would have substantially
         similar annual returns because the shares are invested in the same
         portfolio of securities. The annual returns would differ only to the
         extent that the Classes do not have the same expenses.

The table below shows how the Fund's average annual returns for the periods
shown compare to those of the Merrill Lynch 91-Day Treasury Index and to the
30-Day Money Market Yield Index. The Merrill Lynch 91-Day Treasury Index
consists of short-term U.S. Treasury securities, maturing in 91 days. The 30-Day
Money Market Yield Index is an index of money market funds based on 30-day
yields.

example also assumes that your investment has a 5% return each year and that the

                         INVESTMENT STRATEGIES AND RISKS

CAN A FUND DEPART FROM ITS NORMAL STRATEGIES?

   
Each Fund may depart from its investment strategies by taking temporary
defensive positions in response to adverse market, economic or political
conditions. During these times, a Fund may not achieve its investment goals.
    

DO THE FUNDS ENGAGE IN ACTIVE TRADING OF SECURITIES?

   
The International Equity Fund, Income Opportunity Fund and Bond Fund may engage
in active trading to achieve their investment goals. This may cause the Fund to
realize higher capital gains which would be passed on to you. Higher capital
gains could increase your tax liability. Frequent trading also increases
transactions costs, which would lower the Fund's performance.
    

   
CAN A FUND CHANGE ITS INVESTMENT GOAL?
    

   
A Fund's investment goal(s) may be changed by a vote of the Board of Trustees
without shareholder approval. You would be notified at least 30 days before any
such change took effect.
    

YEAR 2000 RISK.

Touchstone has implemented steps intended to assure that its major computer
systems and processes are capable of Year 2000 processing. We are also examining
the third parties with whom we work to assess their readiness and are developing
contingency plans to assure that any problems in their systems will not
materially affect Touchstone's operations.

Companies or governmental entities in which Touchstone Funds invest could also
be affected by the Year 2000 issue, but at this time the Funds cannot predict
the degree of impact.

Computer systems failure of Touchstone, a Fund Sub-Advisor or that of any Fund
service provider could impair Fund services and have a negative impact on a
Fund's operations and returns.

THE FUNDS AT A GLANCE.

The following two tables can give you a quick basic understanding of the types
of securities a Fund tends to invest in and some of the risks associated with a
Fund's investments. You should read all of the information about a Fund and its
risks before deciding to invest.

Repurchase Agreements are collateralized by obligations issued or guaranteed as 
to both principal and interest by the U.S. Government, its agencies, and 
instrumentalities. A repurchase agreement is a transaction in which a security 
is purchased with a simultaneous commitment to sell it back to the seller (a 
commercial bank or recognized securities dealer) at an agreed upon price on an 
agreed upon date. This date is usually not more than seven days from the date 
of purchase. The resale price reflects the purchase price plus an agreed upon 
market rate of interest, which is unrelated to the coupon rate or maturity of 
the purchased security.

RISKS OF INVESTING IN THE FUNDS

Market Risk. A Fund that invests in common stocks is subject to stock market
risk. Stock prices in general may decline over short or even extended periods,
regardless of the success or failure of a particular company's operations. Stock
markets tend to run in cycles, with periods when stock prices generally go up
and periods when they generally go down. Common stock prices tend to go up and
down more than those of bonds.

  -      Emerging Growth Companies. Investment in Emerging Growth Companies is
         subject to enhanced risks because such companies generally have limited
         product lines, markets or financial resources and often exhibit a lack
         of management depth. The securities of such companies can be difficult
         to sell and are usually more volatile than securities of larger, more
         established companies.

   -      REITs. Investment in REITs is subject to risks similar to those
         associated with the direct ownership of real estate (in addition to
         securities markets risks). REITs are sensitive to factors such as
         changes in real estate values and property taxes, interest rates, cash
         flow of underlying real estate assets, supply and demand, and the
         management skill and creditworthiness of the issuer. REITs may also
         lose value due to changes in tax or other regulatory requirements.

Interest Rate Risk. A Fund that invests in debt securities is subject to the
risk that the market value of the debt securities will decline because of rising
interest rates. The prices of debt securities are generally linked to the
prevailing market interest rates. In general, when interest rates rise, the
prices of debt securities fall, and when interest rates fall, the prices of debt
securities rise. The price volatility of a debt security also depends on its
maturity. Generally, the longer the maturity of a debt security the greater its
sensitivity to changes in interest rates. To compensate investors for this
higher risk, debt securities with longer maturities generally offer higher
yields than debt securities with shorter maturities.

   -     Mortgage-Related Securities. Payments from the pool of loans
         underlying a Mortgage-Related Security may not be enough to meet the
         monthly payments of the Mortgage-Related Security. If this occurs the
         Mortgage-Related Security will lose value. Also, prepayments of
         mortgages or mortgage foreclosures will shorten the life of the pool of
         mortgages underlying a Mortgage-Related Security and will affect the
         average life of the Mortgage-Related Securities held by a Fund.
         Mortgage prepayments vary based on several factors including the level
         of interest rates, general economic conditions, the location and age of
         the mortgage and other demographic conditions. In periods of falling
         interest rates, there are usually more prepayments. The reinvestment of
         cash received from prepayments will, therefore, usually be at a lower
         interest rate than the original investment, lowering a Fund's yield.
         Mortgage-Related Securities may be less likely to increase in value
         during periods of falling interest rates than other debt securities.

Credit Risk. The debt securities in a Fund's portfolio are subject to credit
risk. Credit risk is the possibility that an issuer will fail to make timely
payments of interest or principal. Securities rated in the lowest category of
Investment Grade securities have some risky characteristics and changes in
economic conditions are more likely to cause issuers of these securities to be
unable to make payments.


                                       33
<PAGE>   104
- -        Non-Investment Grade Securities. Non-Investment Grade securities are
         sometimes referred to as junk bonds and are very risky with respect to
         their issuers' ability to make payments of interest and principal.
         There is a high risk that a Fund which invests in Non-Investment Grade
         securities could suffer a loss caused by the default of an issuer of
         such securities. Part of the reason for this high risk is that, in the
         event of a default or bankruptcy, holders of Non-Investment Grade
         securities generally will not receive payments until the holders of all
         other debt have been paid. In addition, the market for Non-Investment
         Grade securities has, in the past, had more frequent and larger price
         changes than the markets for other securities. Non-Investment Grade
         securities can also be more difficult to sell for good value.

Foreign Investing. Investing in foreign securities poses unique risks such as
fluctuation in currency exchange rates, market illiquidity, price volatility,
high trading costs, difficulties in settlement, regulations on stock exchanges,
limits on foreign ownership, less stringent accounting, reporting and disclosure
requirements, and other considerations. In the past, equity and debt instruments
of foreign markets have had more frequent and larger price changes than those of
U.S. markets.

- -        Emerging Markets Risk. Investments in a country that is still
         relatively underdeveloped involves exposure to economic structures that
         are generally less diverse and mature than in the U.S. and to political
         and legal systems which may be less stable. In the past, markets of
         developing countries have had more frequent and larger price changes
         than those of developed countries.

   

- -        Political Risk. Political risk includes a greater potential for
         revolts, and the taking of assets by governments. For example, a Fund
         may invest in Eastern Europe and former states of the Soviet Union.
         These countries were under communist systems that took control of
         private industry. This could occur again in this region or others in
         which a Fund may invest, in which case the Fund may lose all or part of
         its investment in that country's issuers.

INVESTMENT ADVISOR
   

Touchstone Advisors, Inc., (the Advisor or Touchstone Advisors) located at 311
Pike Street, Cincinnati, Ohio 45202 is the investment advisor of the Funds.
    

Touchstone Advisors has been registered as an investment advisor under the
Investment Advisers Act of 1940, as amended (the Advisers Act) since 1994. As of
June 30, 1998, Touchstone Advisors had $361 million in assets under management.

Touchstone Advisors is responsible for selecting Fund Sub-Advisors who have
shown good investment performance in their areas of expertise. The Board of
Trustees of the Trust reviews and must approve the Advisor's selections.
Touchstone considers various factors in evaluating Fund Sub-Advisors, including:

             -      level of knowledge and skill
             -      performance as compared to its peers or benchmark
             -      consistency of performance over five years or more 
             -      level of compliance with investment rules and strategies 
             -      employees, facilities and financial strength 
             -      quality of service

Touchstone will also continually monitor each Fund Sub-Advisor's performance
through various analyses and through in-person, telephone and written
consultations with the Fund Sub-Advisors.

Touchstone discusses its expectations for performance with each Fund
Sub-Advisor. Touchstone provides written evaluations and recommendations to the
Board of Trustees, including whether or not each Fund Sub-Advisor's contract
should be renewed, modified or terminated.

Touchstone is also responsible for running all of the operations of the Funds,
except for those that are subcontracted to the Fund Sub-Advisors, custodian,
transfer agent and administrator.

Two or more Fund Sub-Advisors may manage a Fund, with each managing a portion of
the Fund's assets. If a Fund has more than one Fund Sub-Advisor, Touchstone
allocates how much of a Fund's assets are managed by each Sub-Advisor.
Touchstone may change these allocations from time to time, often based upon the
results of the evaluations of the Fund Sub-Advisors.

Each Fund pays Touchstone a fee for its services. Out of this fee Touchstone
pays each Fund Sub-Advisor a fee for its services.

The fee paid to Touchstone by each Fund for the year ended December 31, 1997 is
shown in the table below.

                            INVESTING WITH TOUCHSTONE


   
    


INVESTING IN THE FUNDS

   
    

   
Class Y shares of each Fund are currently offered only to The Western and 
Southern Life Insurance Company Separate Account A.
    


- - INVESTOR ALERT: Touchstone may choose to refuse any purchase order.

PRICING OF FUND SHARES

   
Each Fund's share price, also called net asset value (NAV), is determined as of
the close of trading (normally 4:00 p.m., Eastern time) every day the New York
Stock Exchange (NYSE) is open. The fund calculates the NAV per share, generally
using market prices, by dividing the total value of each class' net assets by
the number of the class shares outstanding. Shares are purchased at the next
offering price determined after your purchase or sale order is received in
proper form by Touchstone. The offering price is the NAV plus a sales charge, if
applicable.
    


                                       39
<PAGE>   110
The Fund's investments are valued based on market value or, if no market value
is available, based on fair value as determined by the Board of Trustees (or
under their direction). All assets and liabilities initially expressed in
foreign currency values will be converted into U.S. dollar values. Some specific
pricing strategies follow:

- - All short-term dollar-denominated investments that mature in 60 days or less
are valued on the basis of amortized cost which the Board of Trustees has
determined represents fair value.

- - Securities mainly traded on a U.S. exchange are valued at the last sale price
on that exchange or, if no sales occurred during the day, at the current quoted
bid price.

   
- - Securities mainly traded on a non-U.S. exchange are generally valued according
to the preceding closing values on that exchange. However, if an event which 
may change the value of a security occurs after the time that the closing value 
on the non-U.S. exchange was determined, the Board of Trustees might decide to 
value the security based on fair value. This may cause the value of the 
security on the books of the fund to be significantly different from the 
closing value on the non-U.S. exchange and may affect the calculation of NAV.
    


   
- - Because portfolio securities that are primarily listed on non-U.S. exchange
may trade on weekends or other days when a Fund does not price its shares, a
Fund's NAV may change on days when shareholders will not be able to buy or sell
shares.
    

CHOOSING A CLASS OF SHARES

Each of the Funds (other than the Standby Income Fund) offers three classes of
shares - Class A shares, Class C shares and Class Y shares. This Prospectus only
offers Class Y shares. Each class of shares charges different sales charges and
distribution or service fees. The amount of sales charges and other fees you pay
will depend on which class of shares you decide to purchase.

Class Y shares are only available for purchase by pension plans.

The Standby Income Fund does not have share classes and it does not charge sales
charges, distribution fees or service fees. The Standby Income Fund may be
purchased by all investors.

CLASS Y SHARES

The offering price of each Class Y share is equal to its NAV. No sales charge is
applied at any time.

No distribution or service fees are charged on Class Y Shares.

                             THE TRUST AND THE FUNDS

         Touchstone Series Trust (the "Trust") is composed of eight funds:
Emerging Growth Fund, International Equity Fund, Income Opportunity Fund, Value
Plus Fund, Growth & Income Fund, Balanced Fund, Bond Fund (each, a "Fund" and
collectively, the "Funds") and Touchstone Standby Income Fund (the "Standby
Income Fund").

         Each Fund, other than the Standby Income Fund, is divided into three
classes of shares: class A shares ("Class A Shares"), class C shares ("Class C
Shares"), and class Y shares ("Class Y Shares"). Throughout this Statement of
Additional Information (the "SAI"), unless otherwise specified, the term Fund or
Funds refers to all applicable classes of such Fund or Funds.

         Each Fund is an open-end management investment company. The Trust was
formed as a Massachusetts business trust on November 9, 1994.

         Shares of the Funds are sold by Touchstone Securities, Inc.
("Touchstone Securities" or the "Distributor"), the Trust's distributor.
Touchstone Advisors, Inc. ("Touchstone" or the "Advisor") is the investment
advisor of each Fund and the Standby Income Fund. The specific investments of
each Fund are managed on a day-to-day basis by their respective sub- advisors
(collectively, the "Fund Sub-Advisors"). Investors Bank & Trust Company
("Investors Bank" or the "Administrator") serves as administrator, custodian and
fund accounting agent to each Fund.

   
         The Prospectuses, dated January 4, 1999, provide the basic information
investors should know before investing, and may be obtained without charge by
calling the Trust at the telephone number listed on the cover. This Statement of
Additional Information, which is not a prospectus, is intended to provide
additional information regarding the activities and operations of the Trust and
should be read in conjunction with the Prospectuses. This Statement of
Additional Information is not an offer of any Fund for which an investor has not
received a Prospectus.

            DESCRIPTION OF THE FUNDS AND THEIR INVESTMENTS AND RISKS

INVESTMENT GOALS

   
         The investment goal(s) of each Fund is described in the Prospectuses.
There can be no assurance that any Fund will achieve its investment goal(s).
    

INVESTMENT STRATEGIES AND RISKS

         The following provides additional information about the investment
policies and types of securities which may be invested in by one or more Funds.

                FIXED-INCOME AND OTHER DEBT INSTRUMENT SECURITIES

         Fixed-income and other debt instrument securities include all bonds,
high yield or "junk" bonds, municipal bonds, debentures, U.S. Government
securities, mortgage-related securities including government stripped
mortgage-related securities, zero coupon securities and custodial receipts. The
market value of fixed-income obligations of the Funds will be affected by
general changes in interest rates which will result in increases or decreases in
the value of the obligations held by the Funds. The market value of the
obligations held by a Fund can be expected to vary inversely to changes in
prevailing interest rates. As a result, shareholders should anticipate that the
market value of the obligations held by the Fund generally will increase when
prevailing interest rates are declining and generally will decrease when
prevailing interest rates are rising. Shareholders also should recognize that,
in periods of declining interest rates, a Fund's yield will tend to be somewhat
higher than prevailing market rates and, in periods of rising interest rates, a
Fund's yield will tend to be somewhat lower. Also, when interest rates are
falling, the inflow of net new money to a Fund from the continuous sale of its
shares will tend to be invested in instruments producing lower yields than the
balance of its portfolio, thereby reducing the Fund's current yield. In periods
of rising interest rates, the opposite can be expected to occur. In addition,
securities in which a Fund may invest may not yield as high a level of current
income as might be achieved by investing in securities with less liquidity, less
creditworthiness or longer maturities.

   
         Ratings made available by Standard & Poor's Rating Service ("S&P") and 
Moody's Investor Service, Inc. ("Moody's") are relative and subjective
and are not absolute standards of quality. Although these ratings are initial
criteria for selection of portfolio investments, a Fund Sub-Advisor also will
make its own evaluation of these securities. Among the factors that will be
considered are the long term ability of the issuers to pay principal and
interest and general economic trends.
    

         Fixed-income securities may be purchased on a when-issued or
delayed-delivery basis. See "Additional Risks and Investment Techniques --
When-Issued and Delayed-Delivery Securities" below.

COMMERCIAL PAPER

         Commercial paper consists of short-term (usually from 1 to 270 days)
unsecured promissory notes issued by corporations in order to finance their
current operations. A variable amount master demand note (which is a type of
commercial paper) represents a direct borrowing arrangement involving
periodically fluctuating rates of interest under a letter agreement between a
commercial paper issuer and an institutional lender pursuant to which the lender
may determine to invest varying amounts.

         For a description of commercial paper ratings, see the Appendix.

MEDIUM AND LOWER RATED AND UNRATED SECURITIES

         Securities rated in the fourth highest category by S&P or Moody's, BBB
and Baa, respectively, although considered investment grade, may possess
speculative characteristics, and changes in economic or other conditions are
more likely to impair the ability of issuers of these securities to make
interest and principal payments than is the case with respect to issuers of
higher grade bonds.

                                       4
<PAGE>   118
   
         Generally, medium or lower-rated securities and unrated securities of
comparable quality, sometimes referred to as "junk bonds," offer a higher
current yield than is offered by higher rated securities, but also (i) will
likely have some quality and protective characteristics that, in the judgment of
the rating organizations, are outweighed by large uncertainties or major risk
exposures to adverse conditions and (ii) are predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal in
accordance with the terms of the obligation. The yield of junk bonds will
fluctuate over time.
    

   
         The market values of certain of these securities also tend to be more
sensitive to individual corporate developments and changes in economic
conditions than higher quality bonds. In addition, medium and lower rated
securities and comparable unrated securities generally present a higher degree
of credit risk. The risk of loss due to default by these issuers is
significantly greater because medium and lower rated securities and unrated
securities of comparable quality generally are unsecured and frequently are
subordinated to the prior payment of senior indebtedness. Since the risk of
default is higher for lower-rated debt securities, the Fund Sub-Advisor's
research and credit analysis are an especially important part of managing
securities of this type held by a Fund. In light of these risks, the Board of
Trustees of the Trust has instructed the Fund Sub-Advisor, in evaluating the
creditworthiness of an issue, whether rated or unrated, to take various factors
into consideration, which may include, as applicable, the issuer's financial
resources, its sensitivity to economic conditions and trends, the operating
history of and the community support for the facility financed by the issue, the
ability of the issuer's management and regulatory matters.
    

   
         In addition, the market value of securities in lower-rated categories
is more volatile than that of higher quality securities, and the markets in
which medium and lower-rated or unrated securities are traded are more limited
than those in which higher rated securities are traded. The existence of limited
markets may make it more difficult for the Funds to obtain accurate market
quotations for purposes of valuing their respective portfolios and calculating
their respective net asset values. Moreover, the lack of a liquid trading market
may restrict the availability of securities for the Funds to purchase and may
also have the effect of limiting the ability of a Fund to sell securities at
their fair value either to meet redemption requests or to respond to changes in
the economy or the financial markets.
    

   
         Lower-rated debt obligations also present risks based on payment
expectations. If an issuer calls the obligation for redemption, a Fund may have
to replace the security with a lower yielding security, resulting in a decreased
return for shareholders. Also, as the principal value of bonds moves inversely
with movements in interest rates, in the event of rising interest rates the
value of the securities held by a Fund may decline relatively proportionately
more than a portfolio consisting of higher rated securities. If a Fund
experiences unexpected net redemptions, it may be forced to sell its higher
rated bonds, resulting in a decline in the overall credit quality of the
securities held by the Fund and increasing the exposure of the Fund to the risks
of lower rated securities. Investments in zero coupon bonds may be more
speculative and subject to greater fluctuations in value due to changes in
interest rates than bonds that pay interest currently.
    

         Subsequent to its purchase by a Fund, an issue of securities may cease
to be rated or its rating may be reduced below the minimum required for purchase
by the Fund. Neither event will require sale of these securities by the Fund,
but the Fund Sub-Advisor will consider this event in its determination of
whether the Fund should continue to hold the securities.

LOWER-RATED DEBT SECURITIES

         While the market for high yield corporate debt securities has been in
existence for many years and has weathered previous economic downturns, the
1980's brought a dramatic increase in the use of such securities to fund highly
leveraged corporate acquisitions and restructuring. Past experience may not
provide an accurate indication of future performance of the high yield bond
market, especially during periods of economic recession. In fact, from 1989 to
1991, the percentage of lower-rated debt securities that defaulted rose
significantly above prior levels.

         The market for lower-rated debt securities may be thinner and less
active than that for higher rated debt securities, which can adversely affect
the prices at which the former are sold. If market quotations are not available,
lower-rated debt securities will be valued in accordance with procedures
established by the Board of Trustees, including the use of outside pricing
services. Judgment plays a greater role in valuing high yield corporate debt
securities than is the case for securities for which more external sources for
quotations and last sale information is available. Adverse publicity and
changing investor perception may affect the ability of outside pricing services
to value lower-rated debt securities and the ability to dispose of these
securities.

         In considering investments for the Fund, the Fund Sub-Advisor will
attempt to identify those issuers of high yielding debt securities whose
financial condition is adequate to meet future obligations, has improved or is
expected to improve in the future. The Fund Sub-Advisor's analysis focuses on
relative values based on such factors as interest or dividend coverage, asset
coverage, earnings prospects and the experience and managerial strength of the
issuer.

         A Fund may choose, at its expense or in conjunction with others, to
pursue litigation or otherwise exercise its rights as a security holder to seek
to protect the interest of security holders if it determines this to be in the
best interest of the Fund.

                               ILLIQUID SECURITIES

         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 "1933 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 1933 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 securities 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 1933 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 of such investments to the
general public or to certain institutions may not be indicative of their
liquidity.

         The Securities and Exchange Commission (the "SEC") has adopted Rule
144A, which allows a broader institutional trading market for securities
otherwise subject to restriction on their resale to the general public. Rule
144A establishes a "safe harbor" from the registration requirements of the 1933
Act on resales of certain securities to qualified institutional buyers. The
Advisor anticipates that the market for certain restricted securities such as
institutional commercial paper will expand further as a result of this
regulation and the development 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.

         Each Fund Sub-Advisor will monitor the liquidity of Rule 144A
securities in each Fund's portfolio under the supervision of the Board of
Trustees. In reaching liquidity decisions, the Fund Sub-Advisor will consider,
among other things, the following factors: (1) the frequency of trades and
quotes for the security; (2) the number of dealers and other potential
purchasers wishing to purchase or sell the security; (3) dealer undertakings to
make a market in the security and (4) the nature of the security and 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).

         RELATED INVESTMENT POLICIES

         No Fund may invest more than 15% of its net assets in securities which
are illiquid or otherwise not readily marketable. The Trustees of the Trust have
adopted a policy that the International Equity Fund may not invest in illiquid
securities other than Rule 144A securities. If a security becomes illiquid after
purchase by the Fund, the Fund will normally sell the security unless to do so
would not be in the best interests of shareholders.

         Each Fund may purchase securities in the United States that are not
registered for sale under federal securities laws but which can be resold to
institutions under SEC Rule 144A or under an exemption from such laws. Provided
that a dealer or institutional trading market in such securities exists, these
restricted securities or Rule 144A securities are treated as exempt from the
Fund's 15% limit on illiquid securities. The Board of Trustees of the Trust,
with advice and information from the respective Fund Sub-Advisor, will determine
the liquidity of restricted securities or Rule 144A securities by looking at
factors such as 

                                       6
<PAGE>   120
trading activity and the availability of reliable price information and, through
reports from such Fund Sub-Advisor, the Board of Trustees of the Trust will
monitor trading activity in restricted securities. If institutional trading in
restricted securities or Rule 144A securities were to decline, a Fund's
illiquidity could be increased and the Fund could be adversely affected.

         No Fund will invest more than 10% of its total assets in restricted
securities (excluding Rule 144A securities).

                               FOREIGN SECURITIES

         Investing in securities issued by foreign companies and governments
involves considerations and potential risks not typically associated with
investing in obligations issued by the U.S. government and domestic
corporations. Less information may be available about foreign companies than
about domestic companies and foreign companies generally are not subject to
uniform accounting, auditing and financial reporting standards or to other
regulatory practices and requirements comparable to those applicable to domestic
companies. The values of foreign investments are affected by changes in currency
rates or exchange control regulations, restrictions or prohibitions on the
repatriation of foreign currencies, application of foreign tax laws, including
withholding taxes, changes in governmental administration or economic or
monetary policy (in the United States or abroad) or changed circumstances in
dealings between nations. Costs are also incurred in connection with conversions
between various currencies. In addition, foreign brokerage commissions and
custody fees are generally higher than those charged in the United States, and
foreign securities markets may be less liquid, more volatile and less subject to
governmental supervision than in the United States. Investments in foreign
countries could be affected by other factors not present in the United States,
including expropriation, confiscatory taxation, lack of uniform accounting and
auditing standards and potential difficulties in enforcing contractual
obligations and could be subject to extended clearance and settlement periods.

   
EMERGING MARKET SECURITIES
    

   
         Emerging Market Securities are securities that are issued by a company
that (i) is organized under the laws of an emerging market country (any country
other than Australia, Austria, Belgium, Canada, Denmark, Finland, France,
Germany, Holland, Italy, Japan, Luxembourg, New Zealand, Norway, Spain, Sweden,
Switzerland, the United Kingdom and the United States), (ii) has its principal
trading market for its stock in an emerging market country, or (iii) derives at
least 50% of its revenues or profits from corporations within emerging market
countries or has at least 50% of its assets located in emerging market
countries. Investments in securities of issuers based in underdeveloped
countries entail all of the risks of investing in foreign issuers outlined in
this section to a heightened degree. These heightened risks include: (i)
expropriation, confiscatory taxation, nationalization, and less social,
political and economic stability; (ii) the smaller size of the market for such
securities and a low or nonexistent volume of trading, resulting in a lack of
liquidity and in price volatility; (iii) certain national policies which may
restrict a Fund's investment opportunities including restrictions on investing
in issuers in industries deemed sensitive to relevant national interests; and
(iv) in the case of Eastern Europe, the absence of developed capital markets and
legal structures governing private or foreign investment and private property
and the possibility that recent favorable economic and political developments
could be slowed or reversed by unanticipated events.
    

SPECIAL CONSIDERATIONS CONCERNING EASTERN EUROPE

         Investments in companies domiciled in Eastern European countries may be
subject to potentially greater risks than those of other foreign issuers. These
risks include: (i) potentially less social, political and economic stability;
(ii) the small current size of the markets for such securities and the low
volume of trading, which result in less liquidity and in greater price
volatility; (iii) certain national policies which may restrict the Funds'
investment opportunities, including restrictions on investment in issuers or
industries deemed sensitive to national interests; (iv) foreign taxation; (v)
the absence of developed legal structures governing private or foreign
investment or allowing for judicial redress for injury to private property; (vi)
the absence, until recently in certain Eastern European countries, of a capital
market structure or market-oriented economy; and (vii) the possibility that
recent favorable economic developments in Eastern Europe may be slowed or
reversed by unanticipated political or social events in such countries, or in
the Commonwealth of Independent States (formerly the Union of Soviet Socialist
Republics).

         So long as the Communist Party continues to exercise a significant or,
in some cases, dominant role in Eastern European countries, investments in such
countries will involve risks of nationalization, expropriation and confiscatory
taxation. The Communist governments of a number of Eastern European countries
expropriated large amounts of private property in the past, in many cases
without adequate compensation, and there may be no assurance that such
expropriation will not occur in the future. In the event of such expropriation,
a Fund could lose a substantial portion of any investments it has made in the
affected countries. Further, no accounting standards exist in Eastern European
countries. Finally, even though certain Eastern European currencies 

                                       7
<PAGE>   121
may be convertible into U.S. dollars, the conversion rates may be artificial in
relation to the actual market values and may be adverse to the interests of a
Fund's shareholders.

CURRENCY EXCHANGE RATES

         A Fund's share value may change significantly when the currencies,
other than the U.S. dollar, in which the Fund's investments are denominated
strengthen or weaken against the U.S. dollar. Currency exchange rates generally
are determined by the forces of supply and demand in the foreign exchange
markets and the relative merits of investments in different countries as seen
from an international perspective. Currency exchange rates can also be affected
unpredictably by intervention by U.S. or foreign governments or central banks or
by currency controls or political developments in the United States or abroad.

                                     OPTIONS

OPTIONS ON SECURITIES

         The respective Funds may write (sell), to a limited extent, only
covered call and put options ("covered options") in an attempt to increase
income. However, the Fund may forgo the benefits of appreciation on securities
sold or may pay more than the market price on securities acquired pursuant to
call and put options written by the Fund.

         When a Fund writes a covered call option, it gives the purchaser of the
option the right to buy the underlying security at the price specified in the
option (the "exercise price") by exercising the option at any time during the
option period. If the option expires unexercised, the Fund will realize income
in an amount equal to the premium received for writing the option. If the option
is exercised, a decision over which the Fund has no control, the Fund must sell
the underlying security to the option holder at the exercise price. By writing a
covered call option, the Fund forgoes, in exchange for the premium less the
commission ("net premium"), the opportunity to profit during the option period
from an increase in the market value of the underlying security above the
exercise price.

         When a Fund writes a covered put option, it gives the purchaser of the
option the right to sell the underlying security to the Fund at the specified
exercise price at any time during the option period. If the option expires
unexercised, the Fund will realize income in the amount of the premium received
for writing the option. If the put option is exercised, a decision over which
the Fund has no control, the Fund must purchase the underlying security from the
option holder at the exercise price. By writing a covered put option, the Fund,
in exchange for the net premium received, accepts the risk of a decline in the
market value of the underlying security below the exercise price.

         A Fund may terminate its obligation as the writer of a call or put
option by purchasing an option with the same exercise price and expiration date
as the option previously written. This transaction is called a "closing purchase
transaction." Where the Fund cannot effect a closing purchase transaction, it
may be forced to incur brokerage commissions or dealer spreads in selling
securities it receives or it may be forced to hold underlying securities until
an option is exercised or expires.

         When a Fund writes an option, an amount equal to the net premium
received by the Fund is included in the liability section of the Fund's
Statement of Assets and Liabilities as a deferred credit. The amount of the
deferred credit will be subsequently marked to market to reflect the current
market value of the option written. The current market value of a traded option
is the last sale price or, in the absence of a sale, the mean between the
closing bid and asked price. If an option expires on its stipulated expiration
date or if the Fund enters into a closing purchase transaction, the Fund will
realize a gain (or loss if the cost of a closing purchase transaction exceeds
the premium received when the option was sold), and the deferred credit related
to such option will be eliminated. If a call option is exercised, the Fund will
realize a gain or loss from the sale of the underlying security and the proceeds
of the sale will be increased by the premium originally received. The writing of
covered call options may be deemed to involve the pledge of the securities
against which the option is being written.

         When a Fund writes a call option, it will "cover" its obligation by
segregating the underlying security on the books of the Fund's custodian or by
placing liquid securities in a segregated account at the Fund's custodian. When
a Fund writes a put option, it will "cover" its obligation by placing liquid
securities in a segregated account at the Fund's custodian.

                                       8
<PAGE>   122
         A Fund may purchase call and put options on any securities in which it
may invest. The Fund would normally purchase a call option in anticipation of an
increase in the market value of such securities. The purchase of a call option
would entitle the Fund, in exchange for the premium paid, to purchase a security
at a specified price during the option period. The Fund would ordinarily have a
gain if the value of the securities increased above the exercise price
sufficiently to cover the premium and would have a loss if the value of the
securities remained at or below the exercise price during the option period.

         A Fund would normally purchase put options in anticipation of a decline
in the market value of securities in its portfolio ("protective puts") or
securities of the type in which it is permitted to invest. The purchase of a put
option would entitle the Fund, in exchange for the premium paid, to sell a
security, which may or may not be held in the Fund's portfolio, at a specified
price during the option period. The purchase of protective puts is designed
merely to offset or hedge against a decline in the market value of the Fund's
portfolio securities. Put options also may be purchased by the Fund for the
purpose of affirmatively benefiting from a decline in the price of securities
which the Fund does not own. The Fund would ordinarily recognize a gain if the
value of the securities decreased below the exercise price sufficiently to cover
the premium and would recognize a loss if the value of the securities remained
at or above the exercise price. Gains and losses on the purchase of protective
put options would tend to be offset by countervailing changes in the value of
underlying portfolio securities.

         Each Fund has adopted certain other nonfundamental policies concerning
option transactions which are discussed below. The Fund's activities in options
may also be restricted by the requirements of the Internal Revenue Code of 1986,
as amended (the "Code"), for qualification as a regulated investment company.

         The hours of trading for options on securities may not conform to the
hours during which the underlying securities are traded. To the extent that the
option markets close before the markets for the underlying securities,
significant price and rate movements can take place in the underlying securities
markets that cannot be reflected in the option markets. It is impossible to
predict the volume of trading that may exist in such options, and there can be
no assurance that viable exchange markets will develop or continue.

         A Fund may engage in over-the-counter options transactions with
broker-dealers who make markets in these options. At present, approximately ten
broker-dealers, including several of the largest primary dealers in U.S.
Government securities, make these markets. The ability to terminate
over-the-counter option positions is more limited than with exchange-traded
option positions because the predominant market is the issuing broker rather
than an exchange, and may involve the risk that broker-dealers participating in
such transactions will not fulfill their obligations. To reduce this risk, the
Fund will purchase such options only from broker-dealers who are primary
government securities dealers recognized by the Federal Reserve Bank of New York
and who agree to (and are expected to be capable of) entering into closing
transactions, although there can be no guarantee that any such option will be
liquidated at a favorable price prior to expiration. The Fund Sub-Advisor will
monitor the creditworthiness of dealers with whom a Fund enters into such
options transactions under the general supervision of the Board of Trustees.

         RELATED INVESTMENT POLICIES

         Each Fund which invests in equity securities may write or purchase
options on stocks. A call option gives the purchaser of the option the right to
buy, and obligates the writer to sell, the underlying stock at the exercise
price at any time during the option period. Similarly, a put option gives the
purchaser of the option the right to sell, and obligates the writer to buy the
underlying stock at the exercise price at any time during the option period. A
covered call option with respect to which a Fund owns the underlying stock sold
by the Fund exposes the Fund during the term of the option to possible loss of
opportunity to realize appreciation in the market price of the underlying stock
or to possible continued holding of a stock which might otherwise have been sold
to protect against depreciation in the market price of the stock. A covered put
option sold by a Fund exposes the Fund during the term of the option to a
decline in price of the underlying stock.

         To close out a position when writing covered options, a Fund may make a
"closing purchase transaction" which involves purchasing an option on the same
stock with the same exercise price and expiration date as the option which it
has previously written on the stock. The Fund will realize a profit or loss for
a closing purchase transaction if the amount paid to purchase an option is less
or more, as the case may be, than the amount received from the sale thereof. To
close out a position as a purchaser of an option, the Fund may make a "closing
sale transaction" which involves liquidating the Fund's position by selling the
option previously purchased.

<PAGE>   123
OPTIONS ON SECURITIES INDEXES

         Such options give the holder the right to receive a cash settlement
during the term of the option based upon the difference between the exercise
price and the value of the index. Such options will be used for the purposes
described above under "Options on Securities" or, to the extent allowed by law,
as a substitute for investment in individual securities.

         Options on securities indexes entail risks in addition to the risks of
options on securities. The absence of a liquid secondary market to close out
options positions on securities indexes is more likely to occur, although the
Fund generally will only purchase or write such an option if the Fund
Sub-Advisor believes the option can be closed out.

         Use of options on securities indexes also entails the risk that trading
in such options may be interrupted if trading in certain securities included in
the index is interrupted. The Fund will not purchase such options unless the
Advisor and the respective Fund Sub-Advisor each believes the market is
sufficiently developed such that the risk of trading in such options is no
greater than the risk of trading in options on securities.

         Price movements in a Fund's portfolio may not correlate precisely with
movements in the level of an index and, therefore, the use of options on indexes
cannot serve as a complete hedge. Because options on securities indexes require
settlement in cash, the Fund Sub-Advisor may be forced to liquidate portfolio
securities to meet settlement obligations.

         When a Fund writes a put or call option on a securities index it will
cover the position by placing liquid securities in a segregated asset account
with the Fund's custodian.

         Options on securities indexes are generally similar to options on stock
except that the delivery requirements are different. Instead of giving the right
to take or make delivery of stock at a specified price, an option on a security
index gives the holders the right to receive a cash "exercise settlement amount"
equal to (a) the amount, if any, by which the fixed exercise price of the option
exceeds (in the case of a put) or is less than (in the case of a call) the
closing value of the underlying index on the date of the exercise, multiplied by
(b) a fixed "index multiplier." Receipt of this cash amount will depend upon the
closing level of the index upon which the option is based being greater than, in
the case of a call, or less than, in the case of a put, the exercise price of
the option. The amount of cash received will be equal to such difference between
the closing price of the index and the exercise price of the option expressed in
dollars or a foreign currency, as the case may be, times a specified multiple.
The writer of the option is obligated, in return for the premium received, to
make delivery of this amount. The writer may offset its position in securities
index options prior to expiration by entering into a closing transaction on an
exchange or the option may expire unexercised.

         Because the value of an index option depends upon movements in the
level of the index rather than the price of a particular security, whether the
Fund will realize a gain or loss from the purchase or writing of options on an
index depends upon movements in the level of securities prices in the market
generally or, in the case of certain indexes, in an industry or market segment,
rather than movements in price of a particular security. Accordingly, successful
use by a Fund of options on security indexes will be subject to the Fund
Sub-Advisor's ability to predict correctly movement in the direction of that
securities market generally or of a particular industry. This requires different
skills and techniques than predicting changes in the price of individual
securities.

                                       10
<PAGE>   124
         RELATED INVESTMENT POLICIES

         Each Fund may purchase and write put and call options on securities
indexes listed on domestic and, in the case of those Funds which may invest in
foreign securities, on foreign exchanges. A securities index fluctuates with
changes in the market values of the securities included in the index.

         To the extent permitted by U.S. federal or state securities laws, the
International Equity Fund may invest in options on foreign stock indexes in lieu
of direct investment in foreign securities. The Fund may also use foreign stock
index options for hedging purposes.

OPTIONS ON FOREIGN CURRENCIES

         Options on foreign currencies are used for hedging purposes in a manner
similar to that in which futures contracts on foreign currencies, or forward
contracts, are utilized. For example, a decline in the dollar value of a foreign
currency in which portfolio securities are denominated will reduce the dollar
value of such securities, even if their value in the foreign currency remains
constant. In order to protect against such diminutions in the value of portfolio
securities, the Fund may purchase put options on the foreign currency. If the
value of the currency does decline, a Fund will have the right to sell such
currency for a fixed amount in dollars and will thereby offset, in whole or in
part, the adverse effect on its portfolio which otherwise would have resulted.

   
         Conversely, where a rise in the dollar value of a currency in which
securities to be acquired are denominated is projected, thereby increasing the
cost of such securities, the Fund may purchase call options thereon. The
purchase of such options could offset, at least partially, the effects of the
adverse movements in exchange rates. As in the case of other types of options,
however, the benefit to the Fund derived from purchases of foreign currency
options will be reduced by the amount of the premium and related transaction
costs. In addition, where currency exchange rates do not move in the direction
or to the extent anticipated, the Fund could sustain losses on transactions in
foreign currency options which would require it to forego a portion or all of
the benefits of advantageous changes in such rates.
    

   
         Options on foreign currencies may be written for the same types of
hedging purposes. For example, where a Fund anticipates a decline in the dollar
value of foreign currency denominated securities due to adverse fluctuations in
exchange rates, it could, instead of purchasing a put option, write a call
option on the relevant currency. If the expected decline occurs, the options
will most likely not be exercised, and the diminution in value of portfolio
securities will be offset by the amount of the premium received.
    

         Similarly, instead of purchasing a call option to hedge against an
anticipated increase in the dollar cost of securities to be acquired, the Fund
could write a put option on the relevant currency which, if rates move in the
manner projected, will expire unexercised and allow the Fund to hedge such
increased cost up to the amount of the premium. As in the case of other types of
options, however, the writing of a foreign currency option will constitute only
a partial hedge up to the amount of the premium, and only if rates move in the
expected direction. If this does not occur, the option may be exercised and the
Fund would be required to purchase or sell the underlying currency at a loss
which may not be offset by the amount of the premium. Through the writing of
options on foreign currencies, the Fund also may be required to forego all or a
portion of the benefits which might otherwise have been obtained from favorable
movements in exchange rates.

         Certain Funds intend to write covered call options on foreign
currencies. A call option written on a foreign currency by a Fund is "covered"
if the Fund owns the underlying foreign currency covered by the call or has an
absolute and immediate right to acquire that foreign currency without additional
cash consideration (or for additional cash consideration held in a segregated
account by its custodian) upon conversion or exchange of other foreign currency
held in its portfolio. A call option is also covered if the Fund has a call on
the same foreign currency and in the same principal amount as the call written
where the exercise price of the call held (a) is equal to or less than the
exercise price of the call written or (b) is greater than the exercise price of
the call written if the difference is maintained by the Fund in cash and liquid
securities in a segregated account with its custodian.

                                       11
<PAGE>   125
         Certain Funds also intend to write call options on foreign currencies
that are not covered for cross-hedging purposes. A call option on a foreign
currency is for cross-hedging purposes if it is not covered, but is designed to
provide a hedge against a decline in the U.S. dollar value of a security which
the Fund owns or has the right to acquire and which is denominated in the
currency underlying the option due to an adverse change in the exchange rate. In
such circumstances, the Fund collateralizes the option by maintaining in a
segregated account with its custodian, cash or liquid securities in an amount
not less than the value of the underlying foreign currency in U.S. dollars
marked to market daily.

         RELATED INVESTMENT POLICIES

         Each Fund that may invest in foreign securities may write covered put
and call options and purchase put and call options on foreign currencies for the
purpose of protecting against declines in the dollar value of portfolio
securities and against increases in the dollar cost of securities to be
acquired. The Fund may use options on currency to cross-hedge, which involves
writing or purchasing options on one currency to hedge against changes in
exchange rates for a different, but related currency. As with other types of
options, however, the writing of an option on foreign currency will constitute
only a partial hedge up to the amount of the premium received, and the Fund
could be required to purchase or sell foreign currencies at disadvantageous
exchange rates, thereby incurring losses. The purchase of an option on foreign
currency may be used to hedge against fluctuations in exchange rates although,
in the event of exchange rate movements adverse to the Fund's position, it may
not forfeit the entire amount of the premium plus related transaction costs. In
addition, the Fund may purchase call options on currency when the Fund
Sub-Advisor anticipates that the currency will appreciate in value.

         There is no assurance that a liquid secondary market on an options
exchange will exist for any particular option, or at any particular time. If the
Fund is unable to effect a closing purchase transaction with respect to covered
options it has written, the Fund will not be able to sell the underlying
currency or dispose of assets held in a segregated account until the options
expire. Similarly, if the Fund is unable to effect a closing sale transaction
with respect to options it has purchased, it would have to exercise the options
in order to realize any profit and will incur transaction costs upon the
purchase or sale of underlying currency. The Fund pays brokerage commissions or
spreads in connection with its options transactions.

   
         As in the case of forward contracts, certain options on foreign
currencies are traded over-the-counter and involve liquidity and credit risks
which may not be present in the case of exchange-traded currency options. The
Fund's ability to terminate over-the-counter options ("OTC Options") will be
more limited than the exchange-traded options. It is also possible that
broker-dealers participating in OTC Options transactions will not fulfill their
obligations. Until such time as the staff of the SEC changes its position, the
Fund will treat purchased OTC Options and assets used to cover written OTC
Options as illiquid securities. With respect to options written with primary
dealers in U.S. Government securities pursuant to an agreement requiring a
closing purchase transaction at a formula price, the amount of illiquid
securities may be calculated with reference to the repurchase formula.
    

FORWARD CURRENCY CONTRACTS

         Because, when investing in foreign securities, a Fund buys and sells
securities denominated in currencies other than the U.S. dollar and receives
interest, dividends and sale proceeds in currencies other than the U.S. dollar,
such Funds from time to time may enter into forward currency transactions to
convert to and from different foreign currencies and to convert foreign
currencies to and from the U.S. dollar. A Fund either enters into these
transactions on a spot (i.e., cash) basis at the spot rate prevailing in the
foreign currency exchange market or uses forward currency contracts to purchase
or sell foreign currencies.

         A forward currency contract is an obligation by a Fund 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. Forward currency contracts establish an exchange
rate at a future date. These contracts are transferable in the interbank market
conducted directly between currency traders (usually large commercial banks) and
their customers. A forward currency contract generally has no deposit
requirement and is traded at a net price without commission. Each Fund maintains
with its custodian a segregated account of liquid securities in an amount at
least equal to its obligations under each forward currency contract. Neither
spot transactions nor forward currency contracts eliminate fluctuations in the
prices of the Fund's securities or in foreign exchange rates, or prevent loss if
the prices of these securities should decline.

         A Fund may enter into foreign currency hedging transactions in an
attempt to protect against changes in foreign currency exchange rates between
the trade and settlement dates of specific securities transactions or changes in
foreign currency exchange 

                                       12
<PAGE>   126
rates that would adversely affect a portfolio position or an anticipated
investment position. Since consideration of the prospect for currency parities
will be incorporated into a Fund Sub-Advisor's long-term investment decisions, a
Fund will not routinely enter into foreign currency hedging transactions with
respect to security transactions; however, the Fund Sub-Advisors believe that it
is important to have the flexibility to enter into foreign currency hedging
transactions when it determines that the transactions would be in a Fund's best
interest. Although these transactions tend to minimize the risk of loss due to a
decline in the value of the hedged currency, at the same time they tend to limit
any potential gain that might be realized should the value of the hedged
currency increase. The precise matching of the forward currency contract amounts
and the value of the securities involved will not generally be possible because
the future value of such securities in foreign currencies will change as a
consequence of market movements in the value of such securities between the date
the forward currency contract is entered into and the date it matures. The
projection of currency market movements is extremely difficult, and the
successful execution of a hedging strategy is highly uncertain.

   
         While these contracts are not presently regulated by the CFTC, the CFTC
may in the future assert authority to regulate forward currency contracts. In
such event the Fund's ability to utilize forward currency contracts in the
manner set forth in the Prospectuses may be restricted. Forward currency
contracts may reduce the potential gain from a positive change in the
relationship between the U.S. dollar and foreign currencies. Unanticipated
changes in currency prices may result in poorer overall performance for the Fund
than if it had not entered into such contracts. The use of forward currency
contracts may not eliminate fluctuations in the underlying U.S. dollar
equivalent value of the prices of or rates of return on a Fund's foreign
currency denominated portfolio securities and the use of such techniques will
subject a Fund to certain risks.
    

         The matching of the increase in value of a forward currency contract
and the decline in the U.S. dollar equivalent value of the foreign currency
denominated asset that is the subject of the hedge generally will not be
precise. In addition, a Fund may not always be able to enter into forward
currency contracts at attractive prices and this will limit the Fund's ability
to use such contract to hedge or cross-hedge its assets. Also, with regard to a
Fund's use of cross-hedges, there can be no assurance that historical
correlations between the movement of certain foreign currencies relative to the
U.S. dollar will continue. Thus, at any time poor correlation may exist between
movements in the exchange rates of the foreign currencies underlying a Fund's
cross-hedges and the movements in the exchange rates of the foreign currencies
in which the Fund's assets that are the subject of such cross-hedges are
denominated.

               FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

         The successful use of such instruments draws upon the Fund
Sub-Advisor's skill and experience with respect to such instruments and usually
depends on the Fund Sub-Advisor's ability to forecast interest rate and currency
exchange rate movements correctly. Should interest or exchange rates move in an
unexpected manner, a Fund may not achieve the anticipated benefits of futures
contracts or options on futures contracts or may realize losses and thus will be
in a worse position than if such strategies had not been used. In addition, the
correlation between movements in the price of futures contracts or options on
futures contracts and movements in the price of the securities and currencies
hedged or used for cover will not be perfect and could produce unanticipated
losses.

FUTURES CONTRACTS

         A Fund may enter into contracts for the purchase or sale for future
delivery of fixed-income securities or foreign currencies, or contracts based on
financial indexes including any index of U.S. Government securities, foreign
government securities or corporate debt securities. U.S. futures contracts have
been designed by exchanges which have been designated "contracts markets" by the
Commodity Futures Trading Commission ("CFTC"), and must be executed through a
futures commission merchant, or brokerage firm, which is a member of the
relevant contract market. Futures contracts trade on a number of exchange
markets, and, through their clearing corporations, the exchanges guarantee
performance of the contracts as between the clearing members of the exchange. A
Fund may enter into futures contracts which are based on debt securities that
are backed by the full faith and credit of the U.S. Government, such as
long-term U.S. Treasury Bonds, Treasury Notes, Government National Mortgage
Association ("GNMA") modified pass-through mortgage-backed securities and
three-month U.S. Treasury Bills. A Fund may also enter into futures contracts
which are based on bonds issued by entities other than the U.S. Government.

         At the same time a futures contract is purchased or sold, the Fund must
allocate cash or securities as a deposit payment ("initial deposit"). It is
expected that the initial deposit would be approximately 1 1/2% to 5% of a
contract's face value. Daily thereafter, the futures contract is valued and the
payment of "variation margin" may be required, since each day the Fund would
provide or receive cash that reflects any decline or increase in the contract's
value.

         At the time of delivery of securities pursuant to such a contract,
adjustments are made to recognize differences in value arising from the delivery
of securities with a different interest rate from that specified in the
contract. In some (but not many) cases, securities called for by a futures
contract may not have been issued when the contract was written.

         Although futures contracts by their terms call for the actual delivery
or acquisition of securities, in most cases the contractual obligation is
fulfilled before the date of the contract without having to make or take
delivery of the securities. The offsetting of a contractual obligation is
accomplished by buying (or selling, as the case may be) on a commodities
exchange an identical futures contract calling for delivery in the same month.
Such a transaction, which is effected through a member of an exchange, cancels
the obligation to make or take delivery of the securities. Since all
transactions in the futures market are made, offset or fulfilled through a
clearinghouse associated with the exchange on which the contracts are traded,
the Fund will incur brokerage fees when it purchases or sells futures contracts.

         The purpose of the acquisition or sale of a futures contract, in the
case of a Fund which holds or intends to acquire fixed-income securities, is to
attempt to protect the Fund from fluctuations in interest or foreign exchange
rates without actually buying or selling fixed-income securities or foreign
currencies. For example, if interest rates were expected to increase, the Fund
might enter into futures contracts for the sale of debt securities. Such a sale
would have much the same effect as selling an equivalent value of the debt
securities owned by the Fund. If interest rates did increase, the value of the
debt security in the Fund would decline, but the value of the futures contracts
to the Fund would increase at approximately the same rate, thereby keeping the
net asset value of the Fund from declining as much as it otherwise would have.
The Fund could accomplish similar results by selling debt securities and
investing in bonds with short maturities when interest rates are expected to
increase. However, since the futures market is more liquid than the cash market,
the use of futures contracts as an investment technique allows the Fund to
maintain a defensive position without having to sell its portfolio securities.

         Similarly, when it is expected that interest rates may decline, futures
contracts may be purchased to attempt to hedge against anticipated purchases of
debt securities at higher prices. Since the fluctuations in the value of futures
contracts should be similar to those of debt securities, a Fund could take
advantage of the anticipated rise in the value of debt securities without

                                       14
<PAGE>   128
actually buying them until the market had stabilized. At that time, the futures
contracts could be liquidated and the Fund could then buy debt securities on the
cash market.

         When a Fund enters into a futures contract for any purpose, the Fund
will establish a segregated account with the Fund's custodian to collateralize
or "cover" the Fund's obligation consisting of cash or liquid securities from
its portfolio in an amount equal to the difference between the fluctuating
market value of such futures contracts and the aggregate value of the initial
and variation margin payments made by the Fund with respect to such futures
contracts.

         The ordinary spreads between prices in the cash and futures market, due
to differences in the nature of those markets, are subject to distortions.
First, all participants in the futures market are subject to initial deposit and
variation margin requirements. Rather than meeting additional variation margin
requirements, investors may close futures contracts through offsetting
transactions which could distort the normal relationship between the cash and
futures markets. Second, the liquidity of the futures market depends on
participants entering into offsetting transactions rather than making or taking
delivery. To the extent participants decide to make or take delivery, liquidity
in the futures market could be reduced, thus producing distortion. Third, from
the point of view of speculators, the margin deposit requirements in the futures
market are less onerous than margin requirements in the securities market.
Therefore, increased participation by speculators in the futures market may
cause temporary price distortions. Due to the possibility of distortion, a
correct forecast of general interest rate trends by the Fund Sub-Advisor may
still not result in a successful transaction.

         In addition, futures contracts entail risks. Although each applicable
Fund Sub-Advisor believes that use of such contracts will benefit the respective
Fund, if the Fund Sub-Advisor's investment judgment about the general direction
of interest rates is incorrect, a Fund's overall performance would be poorer
than if it had not entered into any such contract. For example, if a Fund has
hedged against the possibility of an increase in interest rates which would
adversely affect the price of debt securities held in its portfolio and interest
rates decrease instead, the Fund will lose part or all of the benefit of the
increased value of its debt securities which it has hedged because it will have
offsetting losses in its futures positions. In addition, in such situations, if
a Fund has insufficient cash, it may have to sell debt securities from its
portfolio to meet daily variation margin requirements. Such sales of bonds may
be, but will not necessarily be, at increased prices which reflect the rising
market. A Fund may have to sell securities at a time when it may be
disadvantageous to do so.

OPTIONS ON FUTURES CONTRACTS

         Each Fund may purchase and write options on futures contracts for
hedging purposes. The purchase of a call option on a futures contract is similar
in some respects to the purchase of a call option on an individual security.
Depending on the pricing of the option compared to either the price of the
futures contract upon which it is based or the price of the underlying debt
securities, it may or may not be less risky than ownership of the futures
contract or underlying debt securities. As with the purchase of futures
contracts, when a Fund is not fully invested it may purchase a call option on a
futures contract to hedge against a market advance due to declining interest
rates.

         The writing of a call option on a futures contract constitutes a
partial hedge against declining prices of the security or foreign currency which
is deliverable upon exercise of the futures contract. If the futures price at
expiration of the option is below the exercise price, a Fund will retain the
full amount of the option premium which provides a partial hedge against any
decline that may have occurred in the Fund's portfolio holdings. The writing of
a put option on a futures contract constitutes a partial hedge against
increasing prices of the security or foreign currency which is deliverable upon
exercise of the futures contract. If the futures price at expiration of the
option is higher than the exercise price, the Fund will retain the full amount
of the option premium which provides a partial hedge against any increase in the
price of securities which the Fund intends to purchase. If a put or call option
the Fund has written is exercised, the Fund will incur a loss which will be
reduced by the amount of the premium it receives. Depending on the degree of
correlation between changes in the value of its portfolio securities and changes
in the value of its futures positions, the Fund's losses from existing options
on futures may to some extent be reduced or increased by changes in the value of
portfolio securities.

         The purchase of a put option on a futures contract is similar in some
respects to the purchase of protective put options on portfolio securities. For
example, a Fund may purchase a put option on a futures contract to hedge its
portfolio against the risk of rising interest rates.

                                       15
<PAGE>   129
         The amount of risk a Fund assumes when it purchases an option on a
futures contract is the premium paid for the option plus related transaction
costs. In addition to the correlation risks discussed above, the purchase of an
option also entails the risk that changes in the value of the underlying futures
contract will not be fully reflected in the value of the option purchased.

         The Fund will not enter into any futures contracts or options on
futures contracts if immediately thereafter the amount of margin deposits on all
the futures contracts of the Fund and premiums paid on outstanding options on
futures contracts owned by the Fund would exceed 5% of the market value of the
total assets of the Fund.

ADDITIONAL RISKS OF OPTIONS ON FUTURES CONTRACTS, FORWARD CONTRACTS AND OPTIONS
ON FOREIGN CURRENCIES

         Unlike transactions entered into by a Fund in futures contracts,
options on foreign currencies and forward contracts are not traded on contract
markets regulated by the CFTC or (with the exception of certain foreign currency
options) by the SEC. To the contrary, such instruments are traded through
financial institutions acting as market-makers, although foreign currency
options are also traded on certain national securities exchanges, such as the
Philadelphia Stock Exchange and the Chicago Board Options Exchange, subject to
SEC regulation. Similarly, options on currencies may be traded over-the-counter.
In an over-the-counter trading environment, many of the protections afforded to
exchange participants will not be available. For example, there are no daily
price fluctuation limits, and adverse market movements could therefore continue
to an unlimited extent over a period of time. Although the purchaser of an
option cannot lose more than the amount of the premium plus related transaction
costs, this entire amount could be lost. Moreover, the option writer and a
trader of forward contracts could lose amounts substantially in excess of their
initial investments, due to the margin and collateral requirements associated
with such positions.

         Options on foreign currencies traded on national securities exchanges
are within the jurisdiction of the SEC, as are other securities traded on such
exchanges. As a result, many of the protections provided to traders on organized
exchanges will be available with respect to such transactions. In particular,
all foreign currency option positions entered into on a national securities
exchange are cleared and guaranteed by the Options Clearing Corporation ("OCC"),
thereby reducing the risk of counterparty default. Further, a liquid secondary
market in options traded on a national securities exchange may be more readily
available than in the over-the-counter market, potentially permitting a Fund to
liquidate open positions at a profit prior to exercise or expiration, or to
limit losses in the event of adverse market movements.

         The purchase and sale of exchange-traded foreign currency options,
however, is subject to the risks of the availability of a liquid secondary
market described above, as well as the risks regarding adverse market movements,
margining of options written, the nature of the foreign currency market,
possible intervention by governmental authorities and the effects of other
political and economic events. In addition, exchange-traded options on foreign
currencies involve certain risks not presented by the over-the-counter market.
For example, exercise and settlement of such options must be made exclusively
through the OCC, which has established banking relationships in applicable
foreign countries for this purpose. As a result, the OCC may, if it determines
that foreign governmental restrictions or taxes would prevent the orderly
settlement of foreign currency option exercises, or would result in undue
burdens on the OCC or its clearing member, impose special procedures on exercise
and settlement, such as technical changes in the mechanics of delivery of
currency, the fixing of dollar settlement prices or prohibitions on exercise.

         As in the case of forward contracts, certain options on foreign
currencies are traded over-the-counter and involve liquidity and credit risks
which may not be present in the case of exchange-traded currency options. A
Fund's ability to terminate over-the-counter options will be more limited than
with exchange-traded options. It is also possible that broker-dealers
participating in over-the-counter options transactions will not fulfill their
obligations. Until such time as the staff of the SEC changes its position, each
Fund will treat purchased over-the-counter options and assets used to cover
written over-the-counter options as illiquid securities. With respect to options
written with primary dealers in U.S. Government securities pursuant to an
agreement requiring a closing purchase transaction at a formula price, the
amount of illiquid securities may be calculated with reference to the repurchase
formula.

         In addition, futures contracts, options on futures contracts, forward
contracts and options on foreign currencies may be traded on foreign exchanges.
Such transactions are subject to the risk of governmental actions affecting
trading in or the prices of foreign currencies or securities. The value of such
positions also could be adversely affected by: (i) other complex foreign
political and economic factors; (ii) lesser availability than in the United
States of data on which to make trading decisions; (iii) delays in the Fund's
ability to act upon economic events occurring in foreign markets during
nonbusiness hours in the United 

                                       16
<PAGE>   130
States; (iv) the imposition of different exercise and settlement terms and
procedures and margin requirements than in the United States; and (v) lesser
trading volume.

FUTURES CONTRACTS AND RELATED OPTIONS

   
         Each Fund may enter into futures contracts and purchase and write
(sell) options on these contracts, including but not limited to interest rate,
securities index and foreign currency futures contracts and put and call options
on these futures contracts. These contracts will be entered into only upon the
agreement of the Fund Sub-Advisor that such contracts are necessary or
appropriate in the management of the Fund's assets. These contracts will be
entered into on exchanges designated by the Commodity Futures Trading Commission
("CFTC") or, consistent with CFTC regulations, on foreign exchanges. These
transactions may be entered into for bona fide hedging and other permissible
risk management purposes including protecting against anticipated changes in the
value of securities a Fund intends to purchase.
    

         No Fund will hedge more than 25% of its total assets by selling
futures, buying puts, and writing calls under normal conditions. In addition, no
Fund will buy futures or write puts whose underlying value exceeds 25% of its
total assets, and no Fund will buy calls with a value exceeding 5% of its total
assets.

         A Fund will not enter into futures contracts and related options for
which the aggregate initial margin and premiums exceed 5% of the fair market
value of the Fund's assets after taking into account unrealized profits and
unrealized losses on any contracts it has entered into.

         A Fund may lose the expected benefit of these futures or options
transactions and may incur losses if the prices of the underlying commodities
move in an unanticipated manner. In addition, changes in the value of the Fund's
futures and options positions may not prove to be perfectly or even highly
correlated with changes in the value of its portfolio securities. Successful use
of futures and related options is subject to a Fund Sub-Advisor's ability to
predict correctly movements in the direction of the securities markets
generally, which ability may require different skills and techniques than
predicting changes in the prices of individual securities. Moreover, futures and
options contracts may only be closed out by entering into offsetting
transactions on the exchange where the position was entered into (or a linked
exchange), and as a result of daily price fluctuation limits there can be no
assurance that an offsetting transaction could be entered into at an
advantageous price at any particular time. Consequently, a Fund may realize a
loss on a futures contract or option that is not offset by an increase in the
value of its portfolio securities that are being hedged or a Fund may not be
able to close a futures or options position without incurring a loss in the
event of adverse price movements.

CERTIFICATES OF DEPOSIT AND BANKERS' ACCEPTANCES

         Certificates of deposit are receipts issued by a depository institution
in exchange for the deposit of funds. The issuer agrees to pay the amount
deposited plus interest to the bearer of the receipt on the date specified on
the certificate. The certificate usually can be traded in the secondary market
prior to maturity. Bankers' acceptances typically arise from short-term credit
arrangements designed to enable businesses to obtain funds to finance commercial
transactions. Generally, an acceptance is a time draft drawn on a bank by an
exporter or an importer to obtain a stated amount of funds to pay for specific
merchandise. The draft is then "accepted" by a bank that, in effect,
unconditionally guarantees to pay the face value of the instrument on its
maturity date. The acceptance may then be held by the accepting bank as an
earning asset or it may be sold in the secondary market at the going rate of
discount for a specific maturity. Although maturities for acceptances can be as
long as 270 days, most acceptances have maturities of six months or less.

LENDING OF FUND SECURITIES

         By lending its securities, a Fund can increase its income by continuing
to receive interest on the loaned securities as well as by either investing the
cash collateral in short-term securities or obtaining yield in the form of
interest paid by the borrower when U.S. Government obligations are used as
collateral. There may be risks of delay in receiving additional collateral or
risks of delay in recovery of the securities or even loss of rights in the
collateral should the borrower of the securities fail financially. Each Fund
will adhere to the following conditions whenever its securities are loaned: (i)
the Fund must receive at least 100 percent cash collateral or equivalent
securities from the borrower; (ii) the borrower must increase this collateral
whenever the market value of the securities including accrued interest rises
above the level of the collateral; (iii) the Fund must 

                                       17
<PAGE>   131
be able to terminate the loan at any time; (iv) the Fund must receive reasonable
interest on the loan, as well as any dividends, interest or other distributions
on the loaned securities, and any increase in market value; (v) the Fund may pay
only reasonable custodian fees in connection with the loan; and (vi) voting
rights on the loaned securities may pass to the borrower; provided, however,
that if a material event adversely affecting the investment occurs, the Board of
Trustees must terminate the loan and regain the right to vote the securities.

DERIVATIVES

         The Funds may invest in various instruments that are commonly known as
derivatives. Generally, a derivative is a financial arrangement, the value of
which is based on, or "derived" from, a traditional security, asset, or market
index. Some "derivatives" such as certain mortgage-related and other
asset-backed securities are in many respects like any other investment, although
they may be more volatile or less liquid than more traditional debt securities.
There are, in fact, many different types of derivatives and many different ways
to use them. There is a range of risks associated with those uses. Futures and
options are commonly used for traditional hedging purposes to attempt to protect
a fund from exposure to changing interest rates, securities prices, or currency
exchange rates and as a low cost method of gaining exposure to a particular
securities market without investing directly in those securities. However, some
derivatives are used for leverage, which tends to magnify the effects of an
instrument's price changes as market conditions change. Leverage involves the
use of a small amount of money to control a large amount of financial assets,
and can in some circumstances, lead to significant losses. A Fund Sub-Advisor
will use derivatives only in circumstances where the Fund Sub-Advisor believes
they offer the most economic means of improving the risk/reward profile of the
Fund. Derivatives will not be used to increase portfolio risk above the level
that could be achieved using only traditional investment securities or to
acquire exposure to changes in the value of assets or indexes that by themselves
would not be purchased for the Fund. The use of derivatives for non-hedging
purposes may be considered speculative. A description of the derivatives that
the Funds may use and some of their associated risks is found below.

ADRS, EDRS AND CDRS

         ADRs are U.S. dollar-denominated receipts typically issued by domestic
banks or trust companies that represent the deposit with those entities of
securities of a foreign issuer. ADRs are publicly traded on exchanges or
over-the-counter in the United States. European Depositary Receipts ("EDRs"),
which are sometimes referred to as Continental Depositary Receipts ("CDRs"), may
also be purchased by the Funds. EDRs and CDRs are generally issued by foreign
banks and evidence ownership of either foreign or domestic securities. Certain
institutions issuing ADRs or EDRs may not be sponsored by the issuer of the
underlying foreign securities. A non-sponsored depository may not provide the
same shareholder information that a sponsored depository is required to provide
under its contractual arrangements with the issuer of the underlying foreign
securities.

U.S. GOVERNMENT SECURITIES

         Each Fund may invest in U.S. Government securities, which are
obligations issued or guaranteed by the U.S. Government, its agencies,
authorities or instrumentalities. Some U.S. Government securities, such as U.S.
Treasury bills, Treasury notes and Treasury bonds, which differ only in their
interest rates, maturities and times of issuance, are supported by the full
faith and credit of the United States. Others are supported by: (i) the right of
the issuer to borrow from the U.S. Treasury, such as securities of the Federal
Home Loan Banks; (ii) the discretionary authority of the U.S. government to
purchase the agency's obligations, such as securities of the FNMA; or (iii) only
the credit of the issuer, such as securities of the Student Loan Marketing
Association. No assurance can be given that the U.S. Government will provide
financial support in the future to U.S. Government agencies, authorities or
instrumentalities that are not supported by the full faith and credit of the
United States.

         Securities guaranteed as to principal and interest by the U.S.
Government, its agencies, authorities or instrumentalities include: (i)
securities for which the payment of principal and interest is backed by an
irrevocable letter of credit issued by the U.S. Government or any of its
agencies, authorities or instrumentalities; and (ii) participation interests in
loans made to foreign governments or other entities that are so guaranteed. The
secondary market for certain of these participation interests is limited and,
therefore, may be regarded as illiquid.

                                       18
<PAGE>   132
MORTGAGE-RELATED SECURITIES

         Each Fund may invest in mortgage-related securities. There are several
risks associated with mortgage-related securities generally. One is that the
monthly cash inflow from the underlying loans may not be sufficient to meet the
monthly payment requirements of the mortgage-related security.

         Prepayment of principal by mortgagors or mortgage foreclosures will
shorten the term of the underlying mortgage pool for a mortgage-related
security. Early returns of principal will affect the average life of the
mortgage-related securities remaining in a Fund. The occurrence of mortgage
prepayments is affected by factors including the level of interest rates,
general economic conditions, the location and age of the mortgage and other
social and demographic conditions. In periods of rising interest rates, the rate
of prepayment tends to decrease, thereby lengthening the average life of a pool
of mortgage-related securities. Conversely, in periods of falling interest rates
the rate of prepayment tends to increase, thereby shortening the average life of
a pool. Reinvestment of prepayments may occur at higher or lower interest rates
than the original investment, thus affecting the yield of a Fund. Because
prepayments of principal generally occur when interest rates are declining, it
is likely that a Fund will have to reinvest the proceeds of prepayments at lower
interest rates than those at which the assets were previously invested. If this
occurs, a Fund's yield will correspondingly decline. Thus, mortgage-related
securities may have less potential for capital appreciation in periods of
falling interest rates than other fixed-income securities of comparable
maturity, although these securities may have a comparable risk of decline in
market value in periods of rising interest rates. To the extent that a Fund
purchases mortgage-related securities at a premium, unscheduled prepayments,
which are made at par, will result in a loss equal to any unamortized premium.

         CMOs are obligations fully collateralized by a portfolio of mortgages
or mortgage-related securities. Payments of principal and interest on the
mortgages are passed through to the holders of the CMOs on the same schedule as
they are received, although certain classes of CMOs have priority over others
with respect to the receipt of prepayments on the mortgages. Therefore,
depending on the type of CMOs in which a Fund invests, the investment may be
subject to a greater or lesser risk of prepayment than other types of
mortgage-related securities.

         Mortgage-related securities may not be readily marketable. To the
extent any of these securities are not readily marketable in the judgment of the
Fund Sub-Advisor, the investment restriction limiting a Fund's investment in
illiquid instruments to not more than 15% of the value of its net assets will
apply.

STRIPPED MORTGAGE-RELATED SECURITIES

         These securities are either issued and guaranteed, or privately-issued
but collateralized by securities issued, by GNMA, FNMA or FHLMC. These
securities represent beneficial ownership interests in either periodic principal
distributions ("principal-only") or interest distributions ("interest-only") on
mortgage-related certificates issued by GNMA, FNMA or FHLMC, as the case may be.
The certificates underlying the stripped mortgage-related securities represent
all or part of the beneficial interest in pools of mortgage loans. The Fund will
invest in stripped mortgage-related securities in order to enhance yield or to
benefit from anticipated appreciation in value of the securities at times when
its Fund Sub-Advisor believes that interest rates will remain stable or
increase. In periods of rising interest rates, the expected increase in the
value of stripped mortgage-related securities may offset all or a portion of any
decline in value of the securities held by the Fund.

         Investing in stripped mortgage-related securities involves the risks
normally associated with investing in mortgage-related securities. See
"Mortgage-Related Securities" above. In addition, the yields on stripped
mortgage-related securities are extremely sensitive to the prepayment
experience on the mortgage loans underlying the certificates collateralizing the
securities. If a decline in the level of prevailing interest rates results in a
rate of principal prepayments higher than anticipated, distributions of
principal will be accelerated, thereby reducing the yield to maturity on
interest-only stripped mortgage-related securities and increasing the yield to
maturity on principal-only stripped mortgage-related securities. Sufficiently
high prepayment rates could result in a Fund not fully recovering its initial
investment in an interest-only stripped mortgage-related security. Under current
market conditions, the Fund expects that investments in stripped
mortgage-related securities will consist primarily of interest-only securities.
Stripped mortgage-related securities are currently traded in an over-the-counter
market maintained by several large investment banking firms. There can be no
assurance that the Fund will be able to effect a trade of a stripped
mortgage-related security at a time when it wishes to do so. The Fund will
acquire stripped mortgage-related securities only if a secondary market for the
securities exists at the time of acquisition. Except for stripped mortgage-
related securities based on fixed rate FNMA and 

                                       19
<PAGE>   133
FHLMC mortgage certificates that meet certain liquidity criteria established by
the Board of Trustees, the Funds will treat government stripped mortgage-related
securities and privately-issued mortgage-related securities as illiquid and will
limit its investments in these securities, together with other illiquid
investments, to not more than 15% of net assets.

ZERO COUPON SECURITIES

         Zero coupon U.S. Government securities are debt obligations that are
issued or purchased at a significant discount from face value. The discount
approximates the total amount of interest the security will accrue and compound
over the period until maturity or the particular interest payment date at a rate
of interest reflecting the market rate of the security at the time of issuance.
Zero coupon securities do not require the periodic payment of interest. These
investments benefit the issuer by mitigating its need for cash to meet debt
service, but also require a higher rate of return to attract investors who are
willing to defer receipt of cash. These investments may experience greater
volatility in market value than U.S. Government securities that make regular
payments of interest. A Fund accrues income on these investments for tax and
accounting purposes, which is distributable to shareholders and which, because
no cash is received at the time of accrual, may require the liquidation of other
portfolio securities to satisfy the Fund's distribution obligations, in which
case the Fund will forego the purchase of additional income producing assets
with these funds. Zero coupon securities include STRIPS, that is, securities
underwritten by securities dealers or banks that evidence ownership of future
interest payments, principal payments or both on certain notes or bonds issued
by the U.S. government, its agencies, authorities or instrumentalities. They
also include Coupons Under Book Entry System ("CUBES"), which are component
parts of U.S. Treasury bonds and represent scheduled interest and principal
payments on the bonds.

LOANS AND OTHER DIRECT DEBT INSTRUMENTS

         These are instruments in amounts owed by a corporate, governmental or
other borrower to another party. They may represent amounts owed to lenders or
lending syndicates (loans and loan participations), to suppliers of goods or
services (trade claims or other receivables) or to other parties. Direct debt
instruments purchased by a Fund may have a maturity of any number of days or
years, may be secured or unsecured, and may be of any credit quality. Direct
debt instruments involve the risk of loss in the case of default or insolvency
of the borrower. Direct debt instruments may offer less legal protection to a
Fund in the event of fraud or misrepresentation. In addition, loan
participations involve a risk of insolvency of the lending bank or other
financial intermediary. Direct debt instruments also may include standby
financing commitments that obligate a Fund to supply additional cash to the
borrower on demand at the time when a Fund would not have otherwise done so,
even if the borrower's condition makes it unlikely that the amount will ever be
repaid.

         These instruments will be considered illiquid securities and so will be
limited, along with a Fund's other illiquid securities, to not more than 15% of
the Fund's net assets.

SWAP AGREEMENTS

         To help enhance the value of its portfolio or manage its exposure to
different types of investments, the Funds may enter into interest rate, currency
and mortgage swap agreements and may purchase and sell interest rate "caps,"
"floors" and "collars."

         In a typical interest rate swap agreement, one party agrees to make
regular payments equal to a floating interest rate on a specified amount (the
"notional principal amount") in return for payments equal to a fixed interest
rate on the same amount for a specified period. If a swap agreement provides for
payment in different currencies, the parties may also agree to exchange the
notional principal amount. Mortgage swap agreements are similar to interest rate
swap agreements, except that notional principal amount is tied to a reference
pool of mortgages.

         In a cap or floor, one party agrees, usually in return for a fee, to
make payments under particular circumstances. For example, the purchaser of an
interest rate cap has the right to receive payments to the extent a specified
interest rate exceeds an agreed level; the purchaser of an interest rate floor
has the right to receive payments to the extent a specified interest rate falls
below an agreed level. A collar entitles the purchaser to receive payments to
the extent a specified interest rate falls outside an agreed range.

         Swap agreements may involve leverage and may be highly volatile;
depending on how they are used, they may have a considerable impact on a Fund's
performance. Swap agreements involve risks depending upon the other party's
creditworthiness 

                                       20
<PAGE>   134
and ability to perform, as judged by the Fund Sub-Advisor, as well as the Fund's
ability to terminate its swap agreements or reduce its exposure through
offsetting transactions.

         All swap agreements are considered as illiquid securities and,
therefore, will be limited, along with all of a Fund's other illiquid
securities, to 15% of that Fund's net assets.

CUSTODIAL RECEIPTS

         Custodial receipts or certificates, such as Certificates of Accrual on
Treasury Securities ("CATS"), Treasury Investors Growth Receipts ("TIGRs") and
Financial Corporation certificates ("FICO Strips"), are securities underwritten
by securities dealers or banks that evidence ownership of future interest
payments, principal payments or both on certain notes or bonds issued by the
U.S. Government, its agencies, authorities or instrumentalities. The
underwriters of these certificates or receipts purchase a U.S. Government
security and deposit the security in an irrevocable trust or custodial account
with a custodian bank, which then issues receipts or certificates that evidence
ownership of the periodic unmatured coupon payments and the final principal
payment on the U.S. Government security. Custodial receipts evidencing specific
coupon or principal payments have the same general attributes as zero coupon
U.S. Government securities, described above. Although typically under the terms
of a custodial receipt a Fund is authorized to assert its rights directly
against the issuer of the underlying obligation, the Fund may be required to
assert through the custodian bank such rights as may exist against the
underlying issuer. Thus, if the underlying issuer fails to pay principal and/or
interest when due, a Fund may be subject to delays, expenses and risks that are
greater than those that would have been involved if the Fund had purchased a
direct obligation of the issuer. In addition, if the trust or custodial account
in which the underlying security has been deposited is determined to be an
association taxable as a corporation, instead of a non-taxable entity, the yield
on the underlying security would be reduced in respect of any taxes paid.

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES

         To secure prices deemed advantageous at a particular time, each Fund
may purchase securities on a when-issued or delayed-delivery basis, in which
case delivery of the securities occurs beyond the normal settlement period;
payment for or delivery of the securities would be made prior to the reciprocal
delivery or payment by the other party to the transaction. A Fund will enter
into when-issued or delayed-delivery transactions for the purpose of acquiring
securities and not for the purpose of leverage. When-issued securities purchased
by the Fund may include securities purchased on a "when, as and if issued" basis
under which the issuance of the securities depends on the occurrence of a
subsequent event, such as approval of a merger, corporate reorganization or debt
restructuring.

         Securities purchased on a when-issued or delayed-delivery basis may
expose a Fund to risk because the securities may experience fluctuations in
value prior to their actual delivery. The Fund does not accrue income with
respect to a when-issued or delayed-delivery security prior to its stated
delivery date. Purchasing securities on a when-issued or delayed-delivery basis
can involve the additional risk that the yield available in the market when the
delivery takes place may be higher than that obtained in the transaction itself.

REPURCHASE AGREEMENTS

         Each of the Funds may engage in repurchase agreement transactions.
Under the terms of a typical repurchase agreement, a 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. This arrangement results in a fixed rate
of return that is not subject to market fluctuations during the Fund's holding
period. A Fund may enter into repurchase agreements with respect to U.S.
Government securities with member banks of the Federal Reserve System and
certain non-bank dealers approved by the Board of Trustees. Under each
repurchase agreement, the selling institution is required to maintain the value
of the securities subject to the repurchase agreement at not less than their
repurchase price. The Fund Sub-Advisor, acting under the supervision of the
Advisor and the Board of Trustees, reviews on an ongoing basis the value of the
collateral and the creditworthiness of those non-bank dealers with whom the Fund
enters into repurchase agreements. In entering into a repurchase agreement, a
Fund bears a risk of loss in the event that the other party to the transaction
defaults on its obligations and the Fund is delayed or prevented from exercising
its rights to dispose of the underlying securities, including 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 

                                       21
<PAGE>   135
asserting those rights and the risk of losing all or a part of the income from
the agreement. Repurchase agreements are considered to be collateralized loans
under the Investment Company Act of 1940, as amended (the "1940 Act").

REVERSE REPURCHASE AGREEMENTS AND FORWARD ROLL TRANSACTIONS

   
         The Funds may enter into reverse repurchase agreements and forward roll
transactions. In a reverse repurchase agreement the Fund agrees to sell
portfolio securities to financial institutions such as banks and broker-dealers
and to repurchase them at a mutually agreed date and price. Forward roll
transactions are equivalent to reverse repurchase agreements but involve
mortgage-backed securities and involve a repurchase of a substantially similar
security. At the time the Fund enters into a reverse repurchase agreement or
forward roll transaction it will place in a segregated custodial account cash or
liquid securities having a value equal to the repurchase price, including
accrued interest. Reverse repurchase agreements and forward roll transactions
involve the risk that the market value of the securities sold by the Fund may
decline below the repurchase price of the securities. Reverse repurchase
agreements and forward roll transactions are considered to be borrowings by a
Fund for purposes of the limitations described in "Certain Investment
Restrictions" below and in the Trust's Statement of Additional Information.
    

TEMPORARY INVESTMENTS

         For temporary defensive purposes during periods when the Fund
Sub-Advisor of a Fund believes, in consultation with the Advisor, that pursuing
the Fund's basic investment strategy may be inconsistent with the best interests
of its shareholders, the Fund may invest its assets without limit in the
following money market instruments: securities issued or guaranteed by the U.S.
government or its agencies or instrumentalities (including those purchased in
the form of custodial receipts), repurchase agreements, certificates of deposit,
master notes, time deposits and bankers' acceptances issued by banks or savings
and loan associations having assets of at least $500 million as of the end of
their most recent fiscal year and high quality commercial paper.

         In addition, for the same purposes the Fund Sub-Advisor of the
International Equity Fund may invest without limit in obligations issued or
guaranteed by foreign governments or by any of their political subdivisions,
authorities, agencies or instrumentalities that are rated at least AA by S&P or
Aa by Moody's or, if unrated, are determined by the Fund Sub-Advisor to be of
equivalent quality. Each Fund also may hold a portion of its assets in money
market instruments or cash in amounts designed to pay expenses, to meet
anticipated redemptions or pending investments in accordance with its objectives
and policies. Any temporary investments may be purchased on a when-issued basis.

CONVERTIBLE SECURITIES

         Convertible securities may offer higher income than the common stocks
into which they are convertible and include fixed-income or zero coupon debt
securities, which may be converted or exchanged at a stated or determinable
exchange ratio into underlying shares of common stock. Prior to their
conversion, convertible securities may have characteristics similar to both
non-convertible debt securities and equity securities.

         While convertible securities generally offer lower yields than
non-convertible debt securities of similar quality, their prices may reflect
changes in the value of the underlying common stock. Convertible securities
entail less credit risk than the issuer's common stock.

REAL ESTATE INVESTMENT TRUSTS

   
         The Growth & Income Fund may invest in REITs, which can generally be
classified as equity REITs, mortgage REITs and hybrid REITs. Equity REITs, which
invest the majority of their assets directly in real property, derive their
income primarily from rents. Equity REITs can also realize capital gains by
selling properties that have appreciated in value. Mortgage REITs, which invest
the majority of their assets in real estate mortgages, derive their income
primarily from interest payments on real estate mortgages in which they are
invested. Hybrid REITs combine the characteristics of both equity REITs and
mortgage REITs.
    

         Investment in REITs is subject to risks similar to those associated
with the direct ownership of real estate (in addition to securities markets
risks). REITs are sensitive to factors such as changes in real estate values and
property taxes, interest 

                                       22
<PAGE>   136
rates, cash flow of underlying real estate assets, supply and demand, and the
management skill and creditworthiness of the issuer. REITs may also be affected
by tax and regulatory requirements.

STANDARD & POOR'S DEPOSITARY RECEIPTS ("SPDRS")

         The Growth & Income Fund may invest in SPDRs. SPDRs typically trade
like a share of common stock and provide investment results that generally
correspond to the price and yield performance of the component common stocks of
the S&P 500 Index. There can be no assurance that this can be accomplished as it
may not be possible for the portfolio to replicate and maintain exactly the
composition and relative weightings of the S&P 500 Index securities. SPDRs are
subject to the risks of an investment in a broadly based portfolio of common
stocks, including the risk that the general level of stock prices may decline,
thereby adversely affecting the value of such investment.

ASSET COVERAGE

         To assure that a Fund's use of futures and related options, as well as
when-issued and delayed-delivery transactions, forward currency contracts and
swap transactions, are not used to achieve investment leverage, the Fund will
cover such transactions, as required under applicable SEC interpretations,
either by owning the underlying securities or by establishing a segregated
account with the Trust's custodian containing liquid securities in an amount at
all times equal to or exceeding the Fund's commitment with respect to these
instruments or contracts.

RATING SERVICES

   
         The ratings of nationally recognized statistical rating organizations
represent their opinions as to the quality of the securities that they undertake
to rate. It should be emphasized, however, that ratings are relative and
subjective and are not absolute standards of quality. Although these ratings are
an initial criterion for selection of portfolio investments, each Fund
Sub-Advisor also makes its own evaluation of these securities, subject to review
by the Board of Trustees of the Trust. After purchase by a Fund, an obligation
may cease to be rated or its rating may be reduced below the minimum required
for purchase by the Fund. Neither event would require a Fund to eliminate the
obligation from its portfolio, but a Fund Sub-Advisor will consider such an
event in its determination of whether a Fund should continue to hold the
obligation. A description of the ratings used herein and in the Funds'
Prospectuses is set forth in the Appendix to the Prospectuses.
    

                                  FUND POLICIES

   
         The following investment restrictions are "fundamental policies" of
each Fund and may not be changed with respect to a Fund without the approval of
a "majority of the outstanding voting securities" of the Fund. "Majority of the
outstanding voting securities" under the Investment Company Act of 1940, as
amended (the "1940 Act"), and as used in this Statement of Additional
Information and the Prospectuses, means, the lesser of (i) 67% or more of the
outstanding voting securities of the Fund present at a meeting if the holders of
more than 50% of the outstanding voting securities of the Fund are present or
represented by proxy or (ii) more than 50% of the outstanding voting securities
of the Fund.
    

         As a matter of fundamental policy, no Fund may (except that no
investment restriction of a Fund shall prevent a Fund from investing all of its
Assets in an open-end investment company with substantially the same investment
objectives):

         (1) borrow money or mortgage or hypothecate assets of the Fund, except
that in an amount not to exceed 1/3 of the current value of the Fund's net
assets, it may borrow money (including through reverse repurchase agreements,
forward roll transactions involving mortgage-backed securities or other
investment techniques entered into for the purpose of leverage), and except that
it may pledge, mortgage or hypothecate not more than 1/3 of such assets to
secure such borrowings, provided that collateral arrangements with respect to
options and futures, including deposits of initial deposit and variation margin,
are not considered a pledge of assets for purposes of this restriction and
except that assets may be pledged to secure letters of credit solely for the
purpose of participating in a captive insurance company sponsored by the
Investment Company Institute; for additional related restrictions, see clause
(i) under the caption "Additional Restrictions" below;

                                       23
<PAGE>   137
   
         (2) underwrite securities issued by other persons except insofar as the
Funds may technically be deemed an underwriter under the 1933 Act in selling a
portfolio security;
    

         (3) make loans to other persons except: (a) through the lending of the
Fund's portfolio securities and provided that any such loans not exceed 30% of
the Fund's total assets (taken at market value); (b) through the use of
repurchase agreements or the purchase of short-term obligations; or (c) by
purchasing a portion of an issue of debt securities of types distributed
publicly or privately;

   
         (4)(a)(all Funds except the Growth & Income Fund) purchase or sell real
estate (including limited partnership interests but excluding securities secured
by real estate or interests therein), interests in oil, gas or mineral leases,
commodities or commodity contracts (except futures and option contracts) in the
ordinary course of business (except that the Fund may hold and sell, for the
Fund's portfolio, real estate acquired as a result of the Fund's ownership of
securities);
    

         (4)(b)(Growth & Income Fund only)

            (i) purchase or sell real estate (except that (a) the Fund may
invest in (i) securities of entities that invest or deal in real estate,
mortgages, or interests therein and (ii) securities secured by real estate or
interests therein and (b) the Fund may hold and sell real estate acquired as a
result of the Fund's ownership of securities;

            (ii) purchase or sell interests in oil, gas or mineral leases,
commodities or commodity contracts (except futures and options contracts) in the
ordinary course or business.

   
         (5) concentrate its investments in any particular industry (excluding
U.S. Government securities), but if it is deemed appropriate for the achievement
of a Fund's investment objective(s), up to 25% of its total assets may be
invested in any one industry;
    

         (6) issue any senior security (as that term is defined in the 1940 Act)
if such issuance is specifically prohibited by the 1940 Act or the rules and
regulations promulgated thereunder, provided that collateral arrangements with
respect to options and futures, including deposits of initial deposit and
variation margin, are not considered to be the issuance of a senior security for
purposes of this restriction; and

         (7) with respect to 75% of its total assets taken at market value,
invest in assets other than cash and cash items (including receivables), U.S.
Government securities, securities of other investment companies and other
securities for purposes of this calculation limited in respect of any one issuer
to an amount not greater in value than 5% of the value of the total assets of
the Fund and to not more than 10% of the outstanding voting securities of such
issuer.

ADDITIONAL RESTRICTIONS

         Each Fund (or the Trust, on behalf of each Fund) will not, as a matter
of "operating policy" (changeable by the Board of Trustees without a shareholder
vote) (except that no operating policy shall prevent a Fund from investing all
of its Assets in an open-end investment company with substantially the same
investment objectives):

(i)      borrow money (including through reverse repurchase agreements or
         forward roll transactions involving mortgage-backed securities or
         similar investment techniques entered into for leveraging purposes),
         except that the Fund may borrow for temporary or emergency purposes up
         to 10% of its total assets; provided, however, that no Fund may
         purchase any security while outstanding borrowings exceed 5%;

(ii)     pledge, mortgage or hypothecate for any purpose in excess of 10% of the
         Fund's total assets (taken at market value), provided that collateral
         arrangements with respect to options and futures, including deposits of
         initial deposit and variation margin, and reverse repurchase agreements
         are not considered a pledge of assets for purposes of this restriction;

                                       24
<PAGE>   138
(iii)    purchase any security or evidence of interest therein on margin, except
         that such short-term credit as may be necessary for the clearance of
         purchases and sales of securities may be obtained and except that
         deposits of initial deposit and variation margin may be made in
         connection with the purchase, ownership, holding or sale of futures;

(iv)     sell any security which it does not own unless by virtue of its
         ownership of other securities it has at the time of sale a right to
         obtain securities, without payment of further consideration, equivalent
         in kind and amount to the securities sold and provided that if such
         right is conditional the sale is made upon the same conditions;

(v)      invest for the purpose of exercising control or management;

(vi)     purchase securities issued by any investment company except by purchase
         in the open market where no commission or profit to a sponsor or dealer
         results from such purchase other than the customary broker's
         commission, or except when such purchase, though not made in the open
         market, is part of a plan of merger or consolidation; provided,
         however, that securities of any investment company will not be
         purchased for the Fund if such purchase at the time thereof would
         cause: (a) more than 10% of the Fund's total assets (taken at the
         greater of cost or market value) to be invested in the securities of
         such issuers; (b) more than 5% of the Fund's total assets (taken at the
         greater of cost or market value) to be invested in any one investment
         company; or (c) more than 3% of the outstanding voting securities of
         any such issuer to be held for the Fund; provided further that, except
         in the case of a merger or consolidation, the Fund shall not purchase
         any securities of any open-end investment company unless the Fund (1)
         waives the investment advisory fee, with respect to assets invested in
         other open-end investment companies and (2) incurs no sales charge in
         connection with the investment;

(vii)    invest more than 15% of the Fund's net assets (taken at the greater of
         cost or market value) in securities that are illiquid or not readily
         marketable (defined as a security that cannot be sold in the ordinary
         course of business within seven days at approximately the value at
         which the Fund has valued the security) not including (a) Rule 144A
         securities that have been determined to be liquid by the Board of
         Trustees; and (b) commercial paper that is sold under section 4(2) of
         the 1933 Act which is not traded flat or in default as to interest or
         principal and either (i) is rated in one of the two highest categories
         by at least two nationally recognized statistical rating organizations
         and the Fund's Board of Trustees have determined the commercial paper
         to be liquid; or (ii) is rated in one of the two highest categories by
         one nationally recognized statistical rating agency and the Fund's
         Board of Trustees have determined that the commercial paper is
         equivalent quality and is liquid;

(viii)   invest more than 10% of the Fund's total assets in securities that are
         restricted from being sold to the public without registration under the
         1933 Act (other than Rule 144A Securities deemed liquid by the Fund's
         Board of Trustees);

(ix)     purchase securities of any issuer if such purchase at the time thereof
         would cause the Fund to hold more than 10% of any class of securities
         of such issuer, for which purposes all indebtedness of an issuer shall
         be deemed a single class and all preferred stock of an issuer shall be
         deemed a single class, except that futures or option contracts shall
         not be subject to this restriction;

(x)      make short sales of securities or maintain a short position, unless at
         all times when a short position is open it owns an equal amount of such
         securities or securities convertible into or exchangeable, without
         payment of any further consideration, for securities of the same issue
         and equal in amount to, the securities sold short, and unless not more
         than 10% of the Fund's net assets (taken at market value) is
         represented by such securities, or securities convertible into or
         exchangeable for such securities, at any one time (the Funds have no
         current intention to engage in short selling);

(xi)     purchase puts, calls, straddles, spreads and any combination thereof if
         by reason thereof the value of the Fund's aggregate investment in such
         classes of securities will exceed 5% of its total assets;

(xii)    write puts and calls on securities unless each of the following
         conditions are met: (a) the security underlying the put or call is
         within the investment policies of the Fund and the option is issued by
         the OCC, except for put and call options issued by non-U.S. entities or
         listed on non-U.S. securities or commodities exchanges; (b) the
         aggregate value of the obligations underlying the puts determined as of
         the date the options are sold shall not exceed 50% of the Fund's net

                                       25
<PAGE>   139
         assets; (c) the securities subject to the exercise of the call written
         by the Fund must be owned by the Fund at the time the call is sold and
         must continue to be owned by the Fund until the call has been
         exercised, has lapsed, or the Fund has purchased a closing call, and
         such purchase has been confirmed, thereby extinguishing the Fund's
         obligation to deliver securities pursuant to the call it has sold; and
         (d) at the time a put is written, the Fund establishes a segregated
         account with its custodian consisting of cash or liquid securities
         equal in value to the amount the Fund will be obligated to pay upon
         exercise of the put (this account must be maintained until the put is
         exercised, has expired, or the Fund has purchased a closing put, which
         is a put of the same series as the one previously written); and

(xiii)   buy and sell puts and calls on securities, stock index futures or
         options on stock index futures, or financial futures or options on
         financial futures unless such options are written by other persons and:
         (a) the options or futures are offered through the facilities of a

                     INVESTMENT ADVISORY AND OTHER SERVICES

ADVISOR

          Touchstone Advisors provides service to each Fund pursuant to
Investment Advisory Agreements with the Trust (the "Advisory Agreements"). The
services provided by the Advisor consist of directing and supervising each Fund
Sub-Advisor, reviewing and evaluating the performance of each Fund Sub-Advisor
and determining whether or not any Fund Sub-Advisor should be replaced. The
Advisor furnishes at its own expense all facilities and personnel necessary in
connection with providing these services. Each respective Advisory Agreement
will continue in effect if such continuance is specifically approved at least
annually by the respective Board of Trustees and by a majority of the respective
Trustees who are not parties to the Advisory Agreement or interested persons of
any such party, at a meeting called for the purpose of voting on the Advisory
Agreement.

         Each Advisory Agreement is terminable, with respect to a Fund or
Standby Income Fund, without penalty on not more than 60 days' nor less than 30
days' written notice by (1) the Trust, when authorized either by (a) in the case
of a Fund or the Standby Income Fund, a majority vote of the shareholders of the
Fund (with the vote of each shareholder being in proportion to the amount of
their investment), or (b) a vote of a majority of the respective Board of
Trustees or (2) the Advisor. Each Advisory Agreement will automatically
terminate in the event of its assignment. Each Advisory Agreement provides that
neither the Advisor nor its personnel shall 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 its services to the Funds, except for willful misfeasance, bad
faith or gross negligence or reckless disregard of its or their obligations and
duties under the Advisory Agreement.

         The Trust's Prospectus contains a description of fees payable to the
Advisor for services under the Advisory Agreements.

         For the periods indicated, the Class A Shares of each Fund and Standby
Income Fund incurred the following investment advisory fees equal on an annual

A Shares of each Fund and Standby Income Fund.

FUND SUB-ADVISORS

         The Advisor has, in turn, entered into a portfolio advisory agreement
(each a "Fund Agreement") with each Fund Sub-Advisor selected by the Advisor for
a Fund or Standby Income Fund. Under the direction of the Advisor and,

respective Fund (or portion of a Fund).

         Each Fund Sub-Advisor furnishes at its own expense all facilities and
personnel necessary in connection with providing these services. Each Fund
Agreement contains provisions similar to those described above with respect to
the Advisory Agreements.

   
         The Advisor pays each Fund Sub-Advisor a fee for its services provided
to the Fund that is computed daily and paid monthly at an annual rate equal to

         Each of the Administration, Fund Accounting and Custodian Agreements
(collectively, the "Agreements") provide that neither Investors Bank nor its
personnel shall be liable for any error of judgment or mistake of law or for any
act or omission, except for willful misfeasance, bad faith or negligence (gross
negligence in respect of the Custodian Agreement) in 



                                       32
<PAGE>   146
the performance of its or their duties or by reason of disregard (reckless
disregard in respect of the Custodian Agreement) of its or their obligations and
duties under the Agreements.

         Each Agreement may not be assigned without the consent of the
non-assigning party, and may be terminated after its Initial Term, with respect
to a Fund, without penalty by majority vote of the shareholders of the Fund or
by either party on not more than 60 days' written notice.

         State Street Bank and Trust Company ("State Street") serves as transfer
agent of the Trust pursuant to a transfer agency agreement. Under its transfer
agency agreement with the Trust, State Street maintains the shareholder account
records for each Fund, handles certain communications between shareholders and
the Trust and causes to be distributed any dividends and distributions payable
by the Trust. State Street may be reimbursed by the Trust for its out-of-pocket
expenses.

DISTRIBUTOR

         The Trustees of the Trust have adopted a Distribution and Services Plan
(the "Distribution Plan") with respect to Class A and Class C shares of each
Fund (except the Standby Income Fund) after having concluded that there was a
reasonable likelihood that the Distribution Plan would benefit each Class of
each such Fund and its shareholders. The Distribution Plan is designed to
promote sales, thereby increasing the net assets of the Fund. Such an increase
may reduce the expense ratio to the extent the Fund's fixed costs are spread
over a larger net asset base. In addition, an increase in net assets may lessen
the adverse effects that could result were the Fund required to liquidate
portfolio securities to meet redemptions. Of course, there is no assurance that
the net assets of the Fund will increase or that the other benefits referred to
above will be realized.

         The Class A Distribution Plan provides that the Trust may pay the
Distributor a fee not to exceed 0.25% per annum of each Fund's average daily net
assets attributable to its class A shares in anticipation of, or as
reimbursement for, expenses incurred in connection with the sale of shares of
the Trust, such as payments to broker-dealers who advise shareholders regarding
the purchase, sale or retention of shares of the Trust, payments to employees of
the Distributor, advertising expenses and the expenses of printing and
distributing prospectuses and reports used for sales purposes, expenses of
preparing and printing sales literature and other distribution-related expenses.

         The Class C Distribution Plan provides that the Trust may pay the
Distributor a fee not to exceed 0.75% per annum of each Fund's average daily net
assets attributable to its class C shares in anticipation of, or as
reimbursement for, expenses incurred in connection with the sale of shares of
the Trust, such as payments to broker-dealers who advise shareholders regarding
the purchase, sale or retention of shares of the Trust, payments to employees of
the Distributor, advertising expenses and the expenses of printing and
distributing prospectuses and reports used for sales purposes, expenses of
preparing and printing sales literature and other distribution-related expenses.

         No Fund is obligated under a Distribution Plan to pay any distribution
or shareholder service expense in excess of the fees described above. Expenses
incurred by the Distributor in one fiscal year in excess of the fees received
from a Fund in that fiscal year do not give rise to any obligation on the part
of a Fund to the Distributor with respect to any future fiscal year. Thus, if a
Distribution Plan were terminated or not continued, no amounts (other than
current amounts accrued but not yet paid) would be owed by a Fund to the
Distributor. Under arrangements with Dealers and others, the Distributor may pay
compensation upon the sale of Fund shares. To finance such payments, the
Distributor may utilize funds obtained from the Advisor which, in turn, may
borrow funds from affiliated or unaffiliated parties. Such borrowings may be
repaid or secured by an assignment of fees payable pursuant to the Distribution
Plan.



                                       33
<PAGE>   147
   
         Each Distribution Plan will continue in effect indefinitely if such
continuance is specifically approved at least annually by a vote of both a
majority of the Trust's Trustees and a majority of the Trust's Trustees who are
not "interested persons of the Trust" and who have no direct or indirect
financial interest in the operation of the Distribution Plan or in any agreement
related to such Plan ("Qualified Trustees"). The Distributor will provide to the
Trustees of the Trust a quarterly written report of amounts expended by it under
each Distribution Plan and the purposes for which such expenditures were made.
The Distribution Plans further provide that the selection and nomination of the
Trust's disinterested Trustees shall be committed to the discretion of the
disinterested Trustees of the Trust. A Distribution Plan may be terminated at
any time by a vote of a majority of the Trust's Qualified Trustees or by a vote
of the shareholders of the Class. The Distribution Plan may not be amended to
increase materially the amount of permitted expenses thereunder without the
approval of shareholders and may not be materially amended in any case without a
vote of the majority of both the Trust's Trustees and the Trust's Qualified
Trustees. No disinterested Trustee has any financial interest in the
Distribution Plan or in any related agreement. The Distributor will preserve
copies of any plan, agreement or report made pursuant to the Distribution Plans
for a period of not less than six years from the date of the Distribution Plan,
and for the first two years the Distributor will preserve such copies in an
easily accessible place.

Plan for the periods indicated with respect to Class A Shares of each Fund:

                    BROKERAGE ALLOCATION AND OTHER PRACTICES

BROKERAGE TRANSACTIONS

         The Fund Sub-Advisors are responsible for decisions to buy and sell
securities, futures contracts and options on such securities and futures for
each Fund, the selection of brokers, dealers and futures commission merchants to
effect transactions and the negotiation of brokerage commissions, if any.
Broker-dealers may receive brokerage commissions on portfolio transactions,
including options, futures and options on futures transactions and the purchase
and sale of underlying securities upon the exercise of options. Orders may be
directed to any broker-dealer or futures commission merchant, including to the
extent and in the manner permitted by applicable law, the Advisor, the Fund
Sub-Advisors or their subsidiaries or affiliates. Purchases and sales of certain
portfolio securities on behalf of a Fund are frequently placed by the Fund
Sub-Advisor with the issuer or a primary or secondary market-maker for these
securities on a net basis, without any brokerage commission being paid by the
Fund. Trading does, however, involve transaction costs. Transactions with
dealers serving as market-makers reflect the spread between the bid and asked
prices. Purchases of underwritten issues may be made which will include an
underwriting fee paid to the underwriter.

         The Fund Sub-Advisors seek to evaluate the overall reasonableness of
the brokerage commissions paid through familiarity with commissions charged on
comparable transactions, as well as by comparing commissions paid by the Fund to
reported commissions paid by others. In placing orders for the purchase and sale
of securities for a Fund, the Fund Sub-Advisors take into account such factors
as price, commission (if any, negotiable in the case of national securities
exchange transactions), size of order, difficulty of execution and skill
required of the executing broker-dealer. The Fund Sub-Advisors review on a
routine basis commission rates, execution and settlement services performed,
making internal and external comparisons.

         The Fund Sub-Advisors are authorized, consistent with Section 28(e) of
the Securities Exchange Act of 1934, as amended, when placing portfolio
transactions for a Fund with a broker to pay a brokerage commission (to the
extent applicable) in excess of that which another broker might have charged for
effecting the same transaction on account of the receipt of research, market or
statistical information. The term "research, market or statistical information"
includes advice as to the value of securities; the advisability of investing in,
purchasing or selling securities; the availability of securities or purchasers
or sellers of securities; and furnishing analyses and reports concerning
issuers, industries, securities, economic factors and trends, portfolio strategy
and the performance of accounts. A Fund Sub-Advisor may use this research
information in managing a Fund's assets, as well as the assets of other clients.

         Consistent with the policy stated above, the Rules of Fair Practice of
the National Association of Securities Dealers, Inc. and such other policies as
the Board of Trustees may determine, the Fund Sub-Advisors may consider sales of
shares of the Trust as a factor in the selection of broker-dealers to execute
portfolio transactions. The Fund Sub-Advisor will make such allocations if
commissions are comparable to those charged by nonaffiliated, qualified
broker-dealers for similar services.

         Except for implementing the policies stated above, there is no
intention to place portfolio transactions with particular brokers or dealers or
groups thereof. In effecting transactions in over-the-counter securities, orders
are placed with the principal market-makers for the security being traded
unless, after exercising care, it appears that more favorable results are
available otherwise.

         Although certain research, market and statistical information from
brokers and dealers can be useful to a Fund and to the corresponding Fund
Sub-Advisor, it is the opinion of the management of the Funds that such
information is only supplementary to the Fund Sub-Advisor's own research effort,
since the information must still be analyzed, weighed and reviewed by the Fund
Sub-Advisor's staff. Such information may be useful to the Fund Sub-Advisor in
providing services to clients other than the Funds, and not all such information
is used by the Fund Sub-Advisor in connection with the Funds. Conversely, such
information provided to the Fund Sub-Advisor by brokers and dealers through whom
other clients of the Fund Sub-Advisor effect securities transactions may be
useful to the Fund Sub-Advisor in providing services to the Funds.

<PAGE>   149

         In certain instances there may be securities which are suitable for a
Fund as well as for one or more of the respective Fund Sub-Advisor's other
clients. Investment decisions for a Fund and for the Fund Sub-Advisor's other
clients are made with a view to achieving their respective investment
objectives. It may develop that a particular security is bought or sold for only
one client even though it might be held by, or bought or sold for, other
clients. Likewise, a particular security may be bought for one or more clients
when one or more clients are selling that same security. Some simultaneous
transactions are inevitable when several clients receive investment advice from
the same investment advisor, particularly when the same security is suitable for
the investment objectives of more than one client. When two or more clients are
simultaneously engaged in the purchase or sale of the same security, the
securities are allocated among clients in a manner believed to be equitable to
each. It is recognized that in some cases this system could have a detrimental
effect on the price or volume of the security as far as a Fund is concerned.
However, it is believed that the ability of a Fund to participate in volume
transactions will produce better executions for the Fund.

CAPITAL STOCK

         The Trust's Amended Declaration of Trust permits the Trustees to issue
an unlimited number of full and fractional shares of beneficial interest (par
value $0.00001 per share). The Trust currently consists of eight series (each a
"Fund" and collectively, the "Funds") of shares. The shares of each series
participate equally in the earnings, dividends and assets of the particular
series. The Trust may create and issue additional series of shares. The Trust's
Declaration of Trust permits the Trustees to divide or combine the shares into a
greater or lesser number of shares without thereby changing the proportionate
beneficial interests in a series. Each share represents an equal proportionate
interest in a series with each other share. Shares have no pre-emptive or
conversion rights. Shares when issued are fully paid and non-assessable, except
as set forth below. Shareholders are entitled to one vote for each share held.

         Each Fund, other than the Standby Income Fund, is divided into three
classes of shares: Class A Shares, Class C Shares and Class Y Shares. The
following discussion applies to all classes of shares.

         The Trust is not required to hold annual meetings of shareholders but
the Trust will hold special meetings of shareholders when in the judgment of the
Trustees it is necessary or desirable to submit matters for a shareholder vote.
Shareholders have, under certain circumstances, the right to communicate with
other shareholders for the purpose of removing 



                                       37
<PAGE>   151

one or more Trustees. Upon liquidation of a Fund, shareholders of that Fund
would be entitled to share pro rata in the net assets of the Fund available for
distribution to shareholders.

   
         The Trust was organized on February 7, 1994 as a "Massachusetts
business trust." Under Massachusetts law, shareholders of such a business trust
may, under certain circumstances, be held personally liable as partners for its
obligations. However, the risk of a shareholder incurring financial loss on
account of shareholder liability is limited to circumstances in which both
inadequate insurance existed and the Trust itself was unable to meet its
obligations. However, the Trust's Declaration of Trust disclaims shareholder
liability for acts or obligations of the Trust and requires that notice of this
disclaimer be given in each agreement, obligation or instrument entered into or
executed by the Trust or a Trustee. The Declaration of Trust provides for
indemnification from the Trust's property for all losses and expenses of any
shareholder held personally liable for the obligations of the Trust. Thus, the
risk of a shareholder's incurring financial loss on account of shareholder
liability is limited to circumstances in which the Trust itself would be unable
to meet its obligations, a possibility that the Trust believes is remote. Upon
payment of any liability incurred by the Trust, the shareholder paying the
liability will be entitled to reimbursement from the general assets of the
Trust. The Trustees intend to conduct the operations of the Trust in a manner so
as to avoid, as far as possible, ultimate liability of the shareholders for
liabilities of the Trust.
    

         Each investor in a Fund may add to or reduce its investment in the Fund
on each day the Fund determines its net asset value. At the close of each such
business day, the value of each investor's beneficial interest in the Fund will
be determined by multiplying the net asset value of the Fund by the percentage,
effective for that day, which represents that investor's share of the aggregate
beneficial interests in the Fund. Any additions or withdrawals which are to be
effected as of the close of business on that day, will then be effected. The
investor's percentage of the aggregate beneficial interests in the Fund will
then be re-computed as the percentage equal to the fraction (i) the numerator of
which is the value of such investor's investment in the Fund as of the close of
business on such day plus or minus, as the case may be, the amount of any
additions to or withdrawals from the investor's investment in the Fund effected
as of the close of business on such day, and (ii) the denominator of which is
the aggregate net asset value of the Fund as of the close of business on such
day plus or minus, as the case may be, the amount of the net additions to or
withdrawals from the aggregate investments in the Fund by all investors in the
Fund. The percentage so determined will then be applied to determine the value
of the investor's interest in the Fund as of the close of business on the
following business day.

         When matters are submitted for shareholder vote or when shareholders
are asked to provide voting instructions, shareholders of each Fund will have
one vote for each full share held and a proportionate, fractional vote for
fractional shares held. The separate vote of a Fund is required on any matter
affecting the Fund unless the interests of each Fund in the matter are identical
or the matter does not affect any interest of the Fund. Shareholders of a Fund
are not entitled to vote or to provide voting instructions on matters that do
not affect the Fund and do not require a separate vote of the Fund. Shareholders
of all Funds will vote together to elect trustees and for certain other matters.
Under certain circumstances the shareholders of one or more Funds could control
the outcome of these votes.

   
         There normally will be no meeting of shareholders for the purpose of
electing Trustees of the Trust unless and until such time as less than a
majority of the Trust's Trustees holding office have been elected by
shareholders, at which time the Trust's Trustees then in office will call a
shareholders meeting for the election of Trustees. Any Trustee of the Trust may
be removed from office upon the vote of shareholders holding at least two-thirds
of the Trust's outstanding shares at a meeting called for that purpose. The
Trustees are required to call such a meeting upon the written request of
shareholders holding at least 10% of the Trust's outstanding shares. The Trust
will also assist shareholders in communicating with one another as provided for
in the 1940 Act.
    

         The Trust sends to each shareholder a semi-annual report and an audited
annual report, each of which includes a list of the investment securities held
by the Funds.

         Shares of the Trust do not have cumulative voting rights, which means
that holders of more than 50% of the shares voting for the election of Trustees
can elect all Trustees. Shares are transferable but have no preemptive,
conversion or subscription rights. Shareholders generally vote by Fund, except
with respect to the election of Trustees and the ratification of the selection
of independent accountants.

sales charges.
    

VALUATION OF SECURITIES

         The value of each security for which readily available market
quotations exists is based on a decision as to the broadest and most
representative market for such security. The value of such security is based
either on the last sale price on a national securities exchange, or, in the
absence of recorded sales, at the readily available closing bid price on such
exchanges, or at the quoted bid price in the over-the-counter market. Securities
listed on a foreign exchange are valued at the last quoted sale price available
before the time net assets are valued. Unlisted securities are valued at the
average of the quoted bid and asked prices in the over-the-counter market. Debt
securities are valued by a pricing service which determines valuations based
upon market transactions for normal, institutional-size trading units of similar
securities. Securities or other assets for which market quotations are not
readily available are valued at fair value in accordance with procedures
established by the Trust. Such procedures include the use of independent pricing
services, which use prices based upon yields or prices of securities of
comparable quality, coupon, maturity and type; indications as to values from
dealers; and general market conditions. All portfolio securities with a
remaining maturity of less than 60 days are valued at amortized cost, which
approximates market.

         The accounting records of the Funds are maintained in U.S. dollars. The
market value of investment securities, other assets and liabilities and forward
contracts denominated in foreign currencies are translated into U.S. dollars at
the prevailing exchange rates at the end of the period. Purchases and sales of
securities, income receipts, and expense payments are translated at the exchange
rate prevailing on the respective dates of such transactions. Reported net
realized gains and losses on foreign currency transactions represent net gains
and losses from sales and maturities of forward currency contracts, disposition
of foreign currencies, currency gains and losses realized between the trade and
settlement dates on securities transactions and the difference between the
amount of net investment income accrued and the U.S. dollar amount actually
received.

         The problems inherent in making a good faith determination of the value
of restricted securities are recognized in the codification effected by SEC
Financial Reporting Release No. 1 ("FRR 1" (formerly Accounting Series Release
No. 113)) which concludes that there is "no automatic formula" for calculating
the value of restricted securities. It recommends that the best method simply is
to consider all relevant factors before making any calculation. According to FRR
1 such factors would include consideration of the:

                  type of security involved, financial statements, cost at date
                  of purchase, size of holding, discount from market value of
                  unrestricted securities of the same class at the time of
                  purchase, special reports prepared by analysts, information as
                  to any transactions or offers with respect to the security,
                  existence of merger proposals or tender offers affecting the
                  security, price and extent of public trading in similar
                  securities of the issuer or comparable companies, and other
                  relevant matters.

         To the extent that the Fund purchases securities which are restricted
as to resale or for which current market quotations are not available, the Fund
Sub-Advisor will value such securities based upon all relevant factors as
outlined in FRR 1.

REDEMPTION IN KIND

   
         Each Fund reserves the right, if conditions exist which make cash
payments undesirable, to honor any request for redemption or repurchase order by
making payment in whole or in part in readily marketable securities chosen by
the Trust, or the Fund, as the case may be, and valued as they are for purposes
of computing the Fund's net asset value, as the case may be (a redemption in
kind). If payment is made in securities, an investor, including the Fund, may
incur transaction expenses in converting these securities into cash. The Trust,
on behalf of each Fund, has elected, however, to be governed by Rule 18f-1 under
the 1940 Act as a result of which each Fund is obligated to redeem shares or
beneficial interests, as the case may be, with respect to any one investor
during any 90-day period, solely in cash up to the lesser of $250,000 or 1% of
the net asset value of the Fund at the beginning of the period.

 ----------

*        There is no initial sales charge on purchases of $1 million or more,
         including purchases involving a Letter of Intent, Right of
         Accumulation, Aggregation or Concurrent Purchases (as described below).
         However, a contingent deferred sales charge ("CDSC") of 1% is imposed
         on such purchases if liquidated within the first year after purchase,
         except for exchanges or certain qualified retirement plans. See
         "Reduced Sales Charges" for information as to ways in which initial
         sales charges may be reduced.

<PAGE>   154

         On sales at net asset value, Dealers may be paid referral fees by the
Distributor directly; such fees will not be borne by the investor.

         From time to time, the Distributor may reallow to Dealers the full
amount of the sales charge.

CLASS C CONTINGENT DEFERRED SALES CHARGE ("CDSC")

         Class C Shares of any Fund may be purchased without an initial sales
charge. However, (with the exception of Standby Income Fund) you will bear your
proportionate share of payments made pursuant to the Trust's distribution and
service plan described hereunder under the caption "Distribution and Service
Plan." Such payments will affect the net asset value of shares in each Fund. In
addition, with the exception of Standby Income Fund, a CDSC of 1.0% applies to
redemptions of shares made within one year after the date of their purchase. No
such charge is imposed if the shares redeemed have been acquired through the
reinvestment of dividends or capital gains distributions or if the amount
redeemed is derived from increases in the value of the account above the amount
of the purchase payments. In determining whether a CDSC is payable, it is
assumed that the redemption is made from the earliest purchase payments(s) that
remain invested in the Funds. To determine if amounts are available for
redemption free of any CDSC, all of your purchase payments (reduced by any
amounts previously withdrawn) are aggregated, and the current value of all
shares to be redeemed is aggregated. All CDSC's are paid to the Distributor.

         The CDSC is waived for redemptions of shares by: (1) current or retired
directors, trustees, partners, officers and employees of a Trust, the Portfolio
Trust, the Distributor, the Advisor or any Portfolio Advisor, certain family
members of the above persons, and trusts or plans primarily for such persons;
(2) trustees or other fiduciaries purchasing shares for certain retirement plans
and (3) participants in certain pension, profit-sharing or employee benefit
plans that are sponsored by the Distributor and its affiliates.

         The CDSC is also waived for exchanges of shares (except if shares
acquired by exchange are then redeemed within 12 months of the initial
purchase); for redemptions in connection with mergers, acquisitions and exchange
offers; for distributions from qualified retirement plans and other employee
benefit plans; for distributions from custodial accounts under Section 403(b)(7)
of the Internal Revenue Code of 1986, as amended (the "Code"), or IRAs due to
death, disability or attainment of age 59 1/2; for tax-free returns of excess
contributions to IRAs; and for any partial or complete redemptions following the
death or disability of a shareholder, provided the redemption is made within one
year of death or initial determination of disability.

   
REDUCED INITIAL SALES CHARGES FOR CLASS A SHARES
    

AGGREGATION

   
         Sales charge discounts are available for certain aggregated
investments. Investments which may be aggregated include those made by you, your
spouse and your children under the age of 21, if all parties are purchasing
shares for their own accounts, which may include purchases through employee
benefit plans such as an IRA, individual-type 403(b) plan or single-participant
Keogh-type plan or by a business solely controlled by these individuals (for
example, the individuals own the entire business) or by a trust (or other
fiduciary arrangement) solely for the benefit of these individuals. Individual
purchases by trustees or other fiduciaries may also be aggregated if the
investments are: (1) for a single trust estate or fiduciary account, including
an employee benefit plan other than those described above; (2) made for two or
more employee benefit plans of a single employer or of affiliated employers as
defined in the 1940 Act, other than employee benefit plans described above; or
(3) for a common trust fund or other pooled account not specifically formed for
the purpose of accumulating Fund shares. Purchases made for nominee or street
name accounts (securities held in the name of a Dealer or another nominee such
as a bank trust department instead of the customer) may not be aggregated with
those made for other accounts and may not be aggregated with other nominee or
street name accounts unless otherwise qualified as described above.
    

CONCURRENT PURCHASES

         To qualify for a reduced sales charge, you may combine concurrent
purchases of shares of two or more Funds (other than the Standby Income Fund).
For example, if you concurrently invest $25,000 in one Fund and $25,000 in
another Fund, the sales charge would be reduced to reflect a $50,000 purchase.



                                       41
<PAGE>   155

RIGHT OF ACCUMULATION

         Reduced sales charges are applicable through a right of accumulation
under which eligible investors are permitted to purchase shares of a Fund at the
offering price applicable to the total of (a) the dollar amount then being
purchased plus (b) an amount equal to the then current net asset value of the
purchaser's combined holdings. For any such right of accumulation to be made
available, the Transfer Agent must be provided at the time of purchase, by the
purchaser or the purchaser's securities dealer, with sufficient information to
permit confirmation of qualification. Acceptance of the purchase order is
subject to such confirmation. The right of accumulation may be amended or
terminated at any time.

LETTER OF INTENT

         Reduced sales charges are applicable to purchases aggregating a minimum
of $25,000 for the Income Opportunity Fund, the Bond Fund, and the Standby
Income Fund and $50,000 for each other Touchstone Fund, of the shares of the
Fund made within a 24 month period starting with the first purchase pursuant to
a Letter of Intent. The Letter of Intent is not a binding obligation to purchase
any amount of shares; however, its execution will result in the purchaser paying
a lower sales charge at the appropriate quantity purchase level. A purchase not
originally made pursuant to a Letter of Intent may be included under a
subsequent Letter of Intent executed within 90 days of such purchase if the
Distributor is informed in writing of this intent within such 90-day period. The
value of shares of the Fund presently held on the date of the first purchase
under the Letter of Intent, may be included as a credit toward the completion of
such Letter, but the reduced sales charge applicable to the amount covered by
such Letter will be applied only to new purchases. If the total amount of shares
does not equal the amount stated in the Letter of Intent, the investor will be
notified and must pay, within 20 days of the expiration of such Letter, the
difference between the sales charge on the shares purchased at the reduced rate
and the sales charge applicable to the shares actually purchased through the
Letter. Shares equal to 5% of the intended amount will be held in escrow during
the 24 month period (while remaining registered in the name of the purchaser)
for this purpose. The first purchase under the Letter of Intent must be 5% of
the dollar amount of such Letter. If, during the term of such Letter, a purchase
brings the total amount invested to an amount equal to or in excess of the
amount indicated in the Letter, the purchaser will be entitled on that purchase
and subsequent purchases to the reduced percentage sales charge which would be
applicable to a single purchase equal to the total dollar value of the shares
then being purchased under such Letter, but there will not be a retroactive
reduction of the sales charges on any previous purchase. The value of any shares
redeemed or otherwise disposed of by the purchaser prior to termination or
completion of the Letter of Intent will be deducted from the total purchases
made under such Letter.

         YOU MUST ADVISE YOUR FINANCIAL ADVISOR IF YOU QUALIFY FOR A REDUCTION
IN SALES CHARGE USING ONE OR ANY COMBINATION OF THE METHODS DESCRIBED ABOVE.

WAIVER OF SALES CHARGE

   
         Sales charges do not apply to shares of the Funds purchased: (1) by
registered representatives or other employees (and their immediate family
members) of broker/dealers, banks or other financial institutions having
agreements with the Distributor; (2) by any director, officer or other employee
(and their immediate family members) of (A) The Western and Southern Life
Insurance Company or any of its affiliates, (B) any Portfolio Advisor; (C)
RogersCasey; (D) Investors Bank & Trust Company; (E) the Transfer Agent; and (F)
those firms that provide legal, accounting, public relations or other services
to the Distributor or Advisor; (3) by clients of any Portfolio Advisor or of
RogersCasey who are referred to the Distributor by a Portfolio Advisor or
RogersCasey; (4) in accounts as to which a broker-dealer charges an asset
management fee, provided the broker-dealer has an agreement with the
Distributor; (5) as part of an employee benefit plan having more than 25
eligible employees or a minimum of $250,000 invested in the Fund; (6) as part of
certain promotional programs established by the Fund and/or Distributor; (7) by
one or more members of a group of persons engaged in a common business,
profession, civic or charitable endeavor or other activity and retirees and
immediate family members of such persons pursuant to a marketing program between
the Distributor and such group; (8) by bank trust departments; and (9) through
Processing Organizations described in the Prospectuses.
    

         There is no initial sales charge on your purchase of shares in a Roth
IRA or Roth Conversion IRA if (1) you purchase the shares with the proceeds of a
redemption made within the previous 180 days from another mutual fund complex
and (2) you paid an initial sales charge or a contingent deferred sales charge
on your investment in the other mutual fund complex.

         Immediate family members are defined as the spouse, parents, siblings,
natural or adopted children, mother-in-law, father-in-law, brother-in-law and
sister-in-law of a director, officer or employee. The term "employee" is deemed
to include current and retired employees.

   
         Exemptions must be qualified in advance by the Distributor. Your
financial advisor should call the Distributor for more information.
    

                              TAXATION OF THE FUNDS

         The Trust intends to qualify annually and to elect each Fund to be
treated as a regulated investment company under the Code.

         To qualify as a regulated investment company, each Fund must, among
other things: (a) derive in each taxable year at least 90% of its gross income
from dividends, interest, payments with respect to securities loans and gains
from the sale or other disposition of stock, securities or foreign currencies or
other income derived with respect to its business of investing in such stock,
securities or currencies; (b) diversify its holdings so that, at the end of each
quarter of the taxable year, (i) at least 50% of the market value of the Fund's
assets is represented by cash and cash items (including receivables), U.S.
Government securities, the securities of other regulated investment companies
and other securities, with such other securities of any one issuer limited for
the purposes of this calculation to an amount not greater than 5% of the value
of the Fund's total assets and not greater than 10% of the outstanding voting
securities of such issuer and (ii) not more than 25% of the value of its total
assets is invested in the securities of any one issuer (other than U.S.
Government securities or the securities of other regulated investment
companies); and (c) distribute at least 90% of its investment company taxable
income (which includes, among other items, dividends, interest and net
short-term capital gains in excess of net long-term capital losses) and its net
tax-exempt interest income, if any, each taxable year.

         As a regulated investment company, each Fund will not be subject to
U.S. federal income tax on its investment company taxable income and net capital
gains (the excess of net long-term capital gains over net short-term capital
losses), if any, that it distributes to shareholders. The Fund intends to
distribute to its shareholders, at least annually, substantially all of its
investment company taxable income and net capital gains. Amounts not distributed
on a timely basis in accordance with a calendar year distribution requirement
are subject to a nondeductible 4% excise tax. To prevent imposition of the
excise tax, the Fund must distribute during each calendar year an amount equal
to the sum of: (1) at least 98% of its ordinary income (not taking into account
any capital gains or losses) for the calendar year; (2) at least 98% of its
capital gains in excess of its capital losses (adjusted for certain ordinary
losses, as prescribed by the Code) for the one-year period ending on October 31
of the calendar year; and (3) any ordinary income and capital gains for previous
years that was not distributed during those years. A distribution will be
treated as paid on December 31 of the current calendar year if it is declared by
the Fund in October, November or December with a record date in such a month and
paid by the Fund during January of the following calendar year. Such
distributions will be taxable to shareholders in the calendar year in which the
distributions are declared, rather than the calendar year in which the
distributions are received. To prevent application of the excise tax, the Fund
intends to make its distributions in accordance with the calendar year
distribution requirement.

         Each Fund shareholder will receive, if appropriate, various written
notices after the close of the Fund's prior taxable year as to the federal
income status of his dividends and distributions which were received from the
Fund during the Fund's prior taxable year. Shareholders should consult their tax
advisors as to any state and local taxes that may apply to these dividends and
distributions. The dollar amount of dividends excluded from federal income
taxation and the dollar amount subject to such income taxation, if any, will
vary for each shareholder depending upon the size and duration of each
shareholder's investment in the Fund. To the extent that the Fund earns taxable
net investment income, the Fund intends to designate as taxable dividends the
same percentage of each dividend as its taxable net investment income bears to
its total net investment income earned. Therefore, the percentage of each
dividend designated as taxable, if any, may vary.

FOREIGN TAXES



                                       43
<PAGE>   157

         Tax conventions between certain countries and the United States may
reduce or eliminate such taxes. It is impossible to determine the effective rate
of foreign tax in advance since the amount of each applicable Fund's assets to
be invested in various countries will vary.

         If the Fund is liable for foreign taxes, and if more than 50% of the
value of the Fund's total assets at the close of its taxable year consists of
stocks or securities of foreign corporations, it may make an election pursuant
to which certain foreign taxes paid by it would be treated as having been paid
directly by shareholders of the entities, such as the corresponding Fund, which
have invested in the Fund. Pursuant to such election, the amount of foreign
taxes paid will be included in the income of the corresponding Fund's
shareholders, and such Fund shareholders (except tax-exempt shareholders) may,
subject to certain limitations, claim either a credit or deduction for the
taxes. Each such Fund shareholder will be notified after the close of the Fund's
taxable year whether the foreign taxes paid will "pass through" for that year
and, if so, such notification will designate (a) the shareholder's portion of
the foreign taxes paid to each such country and (b) the portion which represents
income derived from sources within each such country.

         The amount of foreign taxes for which a shareholder may claim a credit
in any year will generally be subject to a separate limitation for "passive
income," which includes, among other items of income, dividends, interest and
certain foreign currency gains. Because capital gains realized by the Fund on
the sale of foreign securities will be treated as U.S.-source income, the
available credit of foreign taxes paid with respect to such gains may be
restricted by this limitation.

DISTRIBUTIONS

         Dividends paid out of the Fund's investment company taxable income will
be taxable to a U.S. shareholder as ordinary income. Distributions of net
capital gains, if any, designated as capital gain dividends are taxable as
long-term capital gains, regardless of how long the shareholder has held the
Fund's shares, and are not eligible for the dividends-received deduction.
Shareholders receiving distributions in the form of additional shares, rather
than cash, generally will have a cost basis in each such share equal to the net
asset value of a share of the Fund on the reinvestment date. Shareholders will
be notified annually as to the U.S. federal tax status of distributions.

SALE OF SHARES

         Any gain or loss realized by a shareholder upon the sale or other
disposition of any Class of shares of a Fund, or upon receipt of a distribution
in complete liquidation of a Fund, generally will be a capital gain or loss
which will be long-term or short-term, generally depending upon the
shareholder's holding period for the shares. Any loss realized on a sale or
exchange will be disallowed to the extent the shares disposed of are replaced
(including shares acquired pursuant to a dividend reinvestment plan) within a
period of 61 days beginning 30 days before and ending 30 days after disposition
of the shares. In such a case, the basis of the shares acquired will be adjusted
to reflect the disallowed loss. Any loss realized by a shareholder on a
disposition of Fund shares held by the shareholder for six months or less will
be treated as a long-term capital loss to the extent of any distributions of net
capital gains received by the shareholder with respect to such shares.

FOREIGN WITHHOLDING TAXES

         Income received by a Fund from sources within foreign countries may be
subject to withholding and other taxes imposed by such countries.

BACKUP WITHHOLDING

         A Fund may be required to withhold U.S. federal income tax at the rate
of 31% of all taxable distributions payable to shareholders who fail to provide
the Fund with their correct taxpayer identification number or to make required
certifications, or who have been notified by the Internal Revenue Service that
they are subject to backup withholding. Corporate shareholders and certain other
shareholders specified in the Code generally are exempt from such backup
withholding. Backup withholding is not an additional tax. Any amounts withheld
may be credited against the shareholder's U.S. federal income tax liability.

FOREIGN SHAREHOLDERS

         The tax consequences to a foreign shareholder of an investment in a
Fund may be different from those described herein. Foreign shareholders are
advised to consult their own tax advisors with respect to the particular tax
consequences to them of an investment in a Fund.

OTHER TAXATION

         The Trust is organized as a Massachusetts business trust and, under
current law, neither the Trust nor any Fund is liable for any income or
franchise tax in the Commonwealth of Massachusetts, provided that the Fund
continues to qualify as a regulated investment company under Subchapter M of the
Code.

         Fund shareholders may be subject to state and local taxes on their Fund
distributions. Shareholders are advised to consult their own tax advisors with
respect to the particular tax consequences to them of an investment in a Fund.

                             PERFORMANCE INFORMATION

         From time to time, quotations of a Fund's performance may be included
in advertisements, sales literature or shareholder reports. These performance
figures are calculated in the following manner:

YIELD:

         Yields for a Fund used in advertising are computed by dividing the
Fund's interest and dividend income for a given 30-day or one-month period, net
of expenses, by the average number of shares entitled to receive distributions
during the period, dividing this figure by the Fund's net asset value per share
at the end of the period, and annualizing the result (assuming compounding of
income) in order to arrive at an annual percentage rate. Income is calculated
for purposes of yield quotations in accordance with standardized methods
applicable to all stock and bond mutual funds. Dividends from equity investments
are treated as if they were accrued on a daily basis, solely for the purpose of
yield calculations. In general, interest income is reduced with respect to bonds
trading at a premium over their par value by subtracting a portion of the
premium from income on a daily basis, and is increased with respect to bonds
trading at a discount by adding a portion of the discount to daily income.
Capital gains and losses generally are excluded from the calculation.

         Income calculated for the purposes of calculating a Fund's yield
differs from income as determined for other accounting purposes. Because of the
different accounting methods used, and because of the compounding assumed in
yield calculations, the yield quoted for a Fund may differ from the rate of
distributions of the Fund paid over the same period or the rate of income
reported in the Fund's financial statements. For the 30-day period ended
December 31, 1997, the Funds' yields were as follows:

         For the 7-day period ended December 31, 1997, the Standby Income Fund's
yield was 7.16%.

TOTAL RETURN - CLASS A SHARES

         A Fund's standardized average annual total return is calculated for
certain periods by determining the average annual compounded rates of return
over those periods that would cause an investment of $1,000 (with all
distributions reinvested) to reach the value of that investment at the end of
the periods. A Fund may also calculate non-standardized total return figures
which represent aggregate (not annualized) performance over any period or
year-by-year performance, such as the following.

* Commencement of operations


         Any total return quotation provided for a Fund should not be considered
as representative of the performance of the Fund in the future since the net
asset value and public offering price of shares of the Fund will vary based not
only on the type, quality and maturities of the securities held in the
corresponding Fund, but also on changes in the current value of such securities
and on changes in the expenses of the Fund and the corresponding Fund. These
factors and possible differences in the methods used to calculate total return
should be considered when comparing the total return of a Fund to total returns
published for other investment companies or other investment vehicles. Total
return reflects the performance of both principal and income.

         In connection with communicating its performance to current or
prospective shareholders, a Fund also may compare these figures to the
performance of other mutual funds tracked by mutual fund rating services, to the
performance of various indices and investments for which reliable performance
data is available. The performance figures of unmanaged indices may assume
reinvestment of dividends but generally do not reflect deductions for
administrative and management costs. The performance of the Funds may also be
compared to averages, performance ratings, or other information prepared by
recognized mutual fund statistical services. Evaluations of a Fund's performance
made by independent sources may also be used in advertisements concerning the
Fund. Sources for a Fund's performance information could include Asian Wall
Street Journal, Barron's, Business Week, Changing Times, The Kiplinger Magazine,
Consumer Digest, Financial Times, Financial World, Forbes, Fortune, Global
Investor, Investor's Daily, Lipper Analytical Services, Inc.'s Mutual Fund
Performance Analysis, Money, The New York Times, Personal Investing News,

                                    APPENDIX

BOND AND COMMERCIAL PAPER RATINGS

     Set forth below are descriptions of the ratings of Moody's and S&P, which
represent their opinions as to the quality of the securities which they
undertake to rate. It should be emphasized, however, that ratings are relative
and subjective and are not absolute standards of quality.

MOODY'S BOND RATINGS

     Aaa. Bonds which are rated Aaa are judged to be 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 fluctuations of
protective elements may be of greater amplitude or there may be other elements
present which make the long-term risks appear somewhat larger than in Aaa
securities.

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

     Baa. Bonds which are rated Baa 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 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 as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

     B. Bonds which are rated B generally lack characteristics of a 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.

<PAGE>   165


     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.

     Unrated. Where no rating has been assigned or where a rating has been
suspended or withdrawn, it may be for reasons unrelated to the quality of the
issue.

Should no rating be assigned, the reason may be one of the following:

     1.   An application for rating was not received or accepted.

     2.   The issue or issuer belongs to a group of securities that are not
rated as a matter of policy.

     3.   There is a lack of essential data pertaining to the issue or issuer.

     4.   The issue was privately placed, in which case the rating is not
published in Moody's publications.

Suspension or withdrawal may occur if new and material circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable up-to-date data to permit a judgment to be formed; if a bond is
called for redemption; or for other reasons.

Note: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's believes
possess the strongest investment attributes are designated by the symbols Aa-1,
A-1, Baa-1, Ba-1 and B-1.

S&P'S BOND RATINGS

     AAA. Bonds rated AAA have the highest rating assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.

     AA. Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from the higher rated issues only in small degree.

     A. Bonds rated A have a strong capacity to pay interest and repay principal
although they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than bonds in the highest rated
categories.

     BBB. Bonds rated BBB are regarded as having an adequate capacity to pay
interest and repay principal. Whereas they normally exhibit adequate protection
parameters, adverse 


<PAGE>   166


economic conditions or changing circumstances are more likely to lead to a
weakened capacity to pay interest and repay principal for bonds in this category
than in higher rated categories.

     BB, B, CCC, CC, and C. Bonds rated BB, B, CCC, CC, and C are regarded, on
balance, as predominantly speculative with respect to capacity to pay interest
and repay principal in accordance with the terms of this obligation. BB
indicates the lowest degree of speculation and C the highest degree of
speculation. While such bonds will likely have some quality and protective
characteristics, they are outweighed by large uncertainties of major risk
exposures to adverse conditions.

     C1. The rating C1 is reserved for income bonds on which no interest is
being paid.

     D. Bonds rated D are in default, and payment of interest and/or repayment
of principal is in arrears.

Plus (+) or Minus (-). The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

     NR. Indicates that no rating has been requested, that there is insufficient
information on which to base a rating, or that S&P does not rate a particular
type of obligation as a matter of policy.

S&P'S COMMERCIAL PAPER RATINGS

     A is the highest commercial paper rating category utilized by S&P, which
uses the numbers 1+, 1, 2 and 3 to denote relative strength within its A
classification. Commercial paper issues rated A by S&P have the following
characteristics: Liquidity ratios are better than industry average. Long-term
debt rating is A or better. The issuer has access to at least two additional
channels of borrowing. Basic earnings and cash flow are in an upward trend.
Typically, the issuer is a strong company in a well-established industry and has
superior management.

MOODY'S COMMERCIAL PAPER RATINGS

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

Issuers rated Prime-2 (or related 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 related 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 the requirement for relatively high financial
leverage. Adequate alternate liquidity is maintained.

ITEM 25. INDEMNIFICATION.

Under Article V, Section 5.3 of the Trust's Declaration of Trust, (a) subject to
the exceptions and limitations contained in paragraph (b) below: (i) every
person who is or has been a Trustee or officer of the Trust shall be indemnified
by the Trust, to the fullest extent permitted by law (including the 1940 Act) as
currently in effect or as hereinafter amended, against all liability and against
all expenses reasonably incurred or paid by him in connection with any claim,
action, suit or proceeding in which he becomes involved as a party or otherwise
by virtue of his being or having been a Trustee or officer and against amounts
paid or incurred by him in the settlement thereof; (ii) the words "claim",
"action", "suit", or "proceeding" shall apply to all claims, actions, suits or
proceedings (civil, criminal, administrative or other, including appeals),
actual or threatened; and the words "liability" and "expenses" shall include,
without limitation, attorneys' fees, costs, judgments, amounts paid in
settlement, fines, penalties and other liabilities. (b) No indemnification shall
be provided hereunder to a Trustee or officer: (i) against any liability to the
Trust or the Shareholders by reason of a final adjudication by the court or
other body before which the proceeding was brought that he engaged in wilful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his office; (ii) with respect to any matter as to
which he shall have been finally adjudicated not to have acted in good faith in
the reasonable belief that his action was in the best interest of the Trust; or
(iii) in the event of a settlement involving a payment by a Trustee or officer
or other disposition not involving a final adjudication as provided in paragraph
(b)(i) or (b)(ii) above resulting in a payment by a Trustee or officer, unless
there has been either a determination that such Trustee or officer did not
engage in wilful misfeasance, bad faith,



<PAGE>   170


gross negligence or reckless disregard of the duties involved in the conduct of
his office by the court or other body approving the settlement or other
disposition or by a reasonable determination, based upon a review of readily
available facts (as opposed to a full trial-type inquiry) that he did not engage
in such conduct: (A) by a vote of a majority of the Disinterested Trustees
acting on the matter (provided that a majority of the Disinterested Trustees
then in office act on the matter); or (B) by written opinion of independent
legal counsel. (c) Subject to the provisions of the 1940 Act, the Trust may
maintain insurance for the protection of the Trust Property, its present or
former Shareholders, Trustees, officers, employees, independent contractors and
agents in such amount as the Trustees shall deem adequate to cover possible tort
liability (whether or not the Trust would have the power to indemnify such
Persons against such liability), and such other insurance as the Trustees in
their sole judgment shall deem advisable. (d) The rights of indemnification
herein provided shall be severable, shall not affect any other rights to which
any Trustee or officer may now or hereafter be entitled, shall continue as to a
Person who has ceased to be such a Trustee or officer and shall inure to the
benefit of the heirs, executors and administrators of such Person. Nothing
contained herein shall affect any rights to indemnification to which personnel
other than Trustees and officers may be entitled by contract or otherwise under
law. (e) Expenses of preparation and presentation of a defense to any claim,
action, suit, or proceeding of the character described in paragraph (a) of this
Section 5.3 shall be advanced by the Trust prior to final disposition thereof
upon receipt of an undertaking by or on behalf of the recipient to repay such
amount if it is ultimately determined that he is not entitled to indemnification
under this Section 5.3, provided that either: (i) such undertaking is secured by
a surety bond or some other appropriate security or the Trust shall be insured
against losses arising out of any such advances; or (ii) a majority of the
Disinterested Trustees acting on the matter (provided that a majority of the
Disinterested Trustees then in office act on the matter) or an independent legal
counsel in a written opinion, shall determine, based upon a review of readily
available facts (as opposed to a full trial-type inquiry), that there is reason
to believe that the recipient ultimately will be found entitled to
indemnification. As used in this Section 5.3 a "Disinterested Trustee" is one
(i) who is not an "Interested Person" of the Trust (including anyone who has
been exempted from being an "Interested Person" by any rule, regulation or order
of the Commission), and (ii) against whom none of such actions, suits or other
proceedings or another action, suit or other proceeding on the same or similar
grounds is then or had been pending. As used in this Section 5.3, the term
"independent legal counsel" means an attorney who is independent in all respects
from the Trust and from the person or persons who seek indemnification hereunder
and in any event means an attorney who has not been retained by or performed
services for the Trust or any person to be so indemnified within the five years
prior to the Initial request for indemnification pursuant hereto.

Insofar as indemnification for liability arising under the Securities Act of
1933, as amended (the "1933 Act"), may be permitted to Trustees, officers and
controlling persons of the Trust pursuant to the foregoing provisions, or
otherwise, the Trust has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the 1933 Act and is,


<PAGE>   171

therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Trust of expenses incurred or
paid by a Trustee, officer or controlling person of the Trust in the successful
defense of any action, suit or proceeding) is asserted by such Trustee, officer
or controlling person in connection with the securities being registered, the
Trust will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the 1933 Act and will be governed by the final adjudication of such
issue.

                          INVESTMENT ADVISORY AGREEMENT
                             TOUCHSTONE SERIES TRUST

INVESTMENT ADVISORY AGREEMENT, dated as of January 1, 1999, by and between
TOUCHSTONE ADVISORS, INC., an Ohio corporation (the "Advisor"), and TOUCHSTONE
SERIES TRUST (formerly Select Advisors Trust A), a Massachusetts business trust
created pursuant to a Declaration of Trust dated February 7, 1994, as amended
from time to time (the "Trust").

         WHEREAS, the Trust is an open-end diversified management investment
company registered under the Investment Company Act of 1940, as amended, (the
"1940 Act"); and

         WHEREAS, shares of beneficial interest in the Trust are divided into
separate series (each, along with any series which may in the future be
established, a "Fund"); and

         WHEREAS, the Trust desires to avail itself of the services,
information, advice, assistance and facilities of an investment advisor and to
have an investment advisor perform for it various investment advisory and
research services and other management services; and

         WHEREAS, the Advisor is an investment advisor registered under the
Investment Advisers Act of 1940, as amended, and desires to provide investment
advisory services to the Trust;

         NOW THEREFORE, in consideration of the terms and conditions hereinafter
set forth, it is agreed as follows:

         1. EMPLOYMENT OF THE ADVISOR. The Trust hereby employs the Advisor to
manage the investment and reinvestment of the assets of each Fund subject to the
control and direction of the Trust's Board of Trustees, for the period on the
terms hereinafter set forth. The Advisor hereby accepts such employment and
agrees during such period to render the services and to assume the obligations
herein set forth for the compensation herein provided. The Advisor shall for all
purposes herein be deemed to be independent contractor and shall, except as
expressly provided or authorized (whether herein or otherwise), have no
authority to act for or represent the Trust in any way or otherwise be deemed an
agent of the Trust.

         2. OBLIGATIONS OF AND SERVICES TO BE PROVIDED BY THE ADVISOR. In
providing the services and assuming the obligations set forth herein, the
Advisor may, at its expense, employ one or more subadvisors for any Fund. Any
agreement between the Advisor and a subadvisor shall be subject to the renewal,
termination and
<PAGE>   2
amendment provisions of paragraph 10 hereof. The Advisor undertakes to provide
the following services and to assume the following obligations:

            a)   The Advisor will manage the investment and reinvestment of the
                 assets of each Fund, subject to and in accordance with the
                 respective investment objectives and policies of each Fund and
                 any directions which the Trust's Board of Trustees may issue
                 from time to time. In pursuance of the foregoing, the Advisor
                 may engage separate investment advisors ("Sub-Advisor(s)") to
                 make all determinations with respect to the investment of the
                 assets of each Fund, to effect the purchase and sale of
                 portfolio securities and to take such steps as may be necessary
                 to implement the same. Such determination and services by each
                 Sub-Advisor shall also include determining the manner in which
                 voting rights, rights to consent to corporate action and any
                 other rights pertaining to the portfolio securities shall be
                 exercised. The Advisor shall, and shall cause each Sub-Advisor
                 to, render regular reports to the Trust's Board of Trustees
                 concerning the Trust's and each Fund's investment activities.

            b)   The Advisor shall, or shall cause the respective Sub-Advisor(s)
                 to place orders for the execution of all portfolio
                 transactions, in the name of the respective Fund and in
                 accordance with the policies with respect thereto set forth in
                 the Trust's registration statements under the 1940 Act and the
                 Securities Act of 1933, as such registration statements may be
                 amended from time to time. In connection with the placement of
                 orders for the execution of portfolio transactions, the Advisor
                 shall create and maintain (or cause the Sub-Advisors to create
                 and maintain) all necessary brokerage records for each Fund,
                 which records shall comply with all applicable laws, rules and
                 regulations, including but not limited to records required by
                 Section 31(a) of the 1940 Act. All records shall be the
                 property of the Trust and shall be available for inspection and
                 use by the Securities and Exchange Commission (the "SEC"), the
                 Trust or any person retained by the Trust. Where applicable,
                 such records shall be maintained by the Advisor (or
                 Sub-Advisor) for the periods and in the places required by Rule
                 31a-2 under the 1940 Act.

            c)   In the event of any reorganization or other change in the
                 Advisor, its investment principals, supervisors or members of
                 its investment (or comparable) committee, the Advisor shall
                 give the Trust's Board of Trustees written notice of such
                 reorganization or change within a reasonable time (but not
                 later than 30 days) after such reorganization or change.


                                        2
<PAGE>   3
            d)   The Advisor shall bear its expenses of providing services to
                 the Trust pursuant to this Agreement except such expenses as
                 are undertaken by the Trust. In addition, the Advisor shall pay
                 the salaries and fees, if any, of all Trustees, officers and
                 employees of the Trust who are affiliated persons, as defined
                 in Section 2(a)(3) of the 1940 Act, of the Advisor.

            e)   The Advisor will manage, or will cause the Sub-Advisors to
                 manage, the Fund assets and the investment and reinvestment of
                 such assets so as to comply with the provisions of the 1940 Act
                 and with Subchapter M of the Internal Revenue Code of 1986, as
                 amended.

         3. EXPENSES. The Trust shall pay the expenses of its operation,
including but not limited to (i) charges and expenses for Trust accounting,
pricing and appraisal services and related overhead, (ii) the charges and
expenses of the Trust's auditors; (iii) the charges and expenses of any
custodian, transfer agent, plan agent, dividend disbursing agent and registrar
appointed by the Trust with respect to the Funds; (iv) brokers' commissions, and
issue and transfer taxes, chargeable to the Trust in connection with securities
transactions to which the Trust is a party; (v) insurance premiums, interest
charges, dues and fees for Trust membership in trade associations and all taxes
and fees payable by the Trust to federal, state or other governmental agencies;
(vi) fees and expenses involved in registering and maintaining registrations of
the Trust and/or shares of the Trust with the SEC, state or blue sky securities
agencies and foreign countries, including the preparation of Prospectuses and
Statements of Additional Information for filing with the SEC; (vii) all expenses
of meetings of Trustees and of shareholders of the Trust and of preparing,
printing and distributing prospectuses, notices, proxy statements and all
reports to shareholders and to governmental agencies; (viii) charges and
expenses of legal counsel to the Trust; (ix) compensation of Trustees of the
Trust; (x) the cost of preparing and printing share certificates; and (xi)
interest on borrowed money, if any.

         4. COMPENSATION OF THE ADVISOR.

            a)   As compensation for the services rendered and obligations
                 assumed hereunder by the Advisor, the Trust shall pay to the
                 Advisor monthly a fee that is equal on an annual basis to that
                 percentage of the average daily net assets of each Fund set
                 forth on Schedule 1 attached hereto (and with respect to any
                 future Fund, such percentage as the Trust and the Advisor may
                 agree to from time to time). Such fee shall be computed and
                 accrued daily. If the Advisor serves as investment advisor for
                 less than the whole of any period specified in this Section 4a,
                 the compensation to the Advisor shall be prorated. For purposes
                 of calculating the Advisor's fee, the daily value of each
                 Fund's net assets shall be computed by the same method as the
                 Trust uses to compute the net asset value of that Fund.


                                       3
<PAGE>   4
            b)   The Advisor will pay all fees owing to each Sub-Advisor, and
                 the Trust shall not be obligated to the Sub-Advisors in any
                 manner with respect to the compensation of such Sub-Advisors.

            c)   The Advisor reserves the right to waive all or a part of its
                 fee.

         5. ACTIVITIES OF THE ADVISOR. The services of the Advisor to the Trust
hereunder are not to be deemed exclusive, and the Advisor shall be free to
render similar services to others. It is understood that the Trustees and
officers of the Trust are or may become interested in the Advisor as
stockholders, officers or otherwise, and that stockholders and officers of the
Advisor are or may become similarly interested in the Trust, and that the
Advisor may become interested in the Trust as a shareholder or otherwise.

         6. USE OF NAMES. The Trust will not use the name of the Advisor in any
prospectus, sales literature or other material relating to the Trust in any
manner not approved prior thereto by the Advisor; except that the Trust may use
such name in any document which merely refers in accurate terms to its
appointment hereunder or in any situation which is required by the SEC or a
state securities commission; and provided further, that in no event shall such
approval be unreasonably withheld. The Advisor will not use the name of the
Trust in any material relating to the Advisor in any manner not approved prior
thereto by the Trust; except that the Advisor may use such name in any document
which merely refers in accurate terms to the appointment of the Advisor
hereunder or in any situation which is required by the SEC or a state securities
commission. In all other cases, the parties may use such names to the extent
that the use is approved by the party named, it being agreed that in no event
shall such approval be unreasonably withheld.

            The Trustees of the Trust acknowledge that, in consideration of the
Advisor's assumption of certain organization expenses of the Trust and of the
various Funds, the Advisor has reserved for itself the rights to the name
"Touchstone Series Trust" (or any similar names) and that use by the Trust of
such name shall continue only with the continuing consent of the Advisor, which
consent may be withdrawn at any time, effective immediately, upon written notice
thereof to the Trust.

         7. LIMITATION OF LIABILITY OF THE ADVISOR.

            a)   Absent willful misfeasance, bad faith, gross negligence, or
                 reckless disregard of obligations or duties hereunder on the
                 part of the Advisor, the Advisor shall not be subject to
                 liability to the Trust or to any holder of an interest in any
                 Fund for any act or omission in the course of, or connected
                 with, rendering services hereunder or for any losses that may
                 be sustained in the purchase, holding or sale of any security.
                 As used in this Section 7, the term "Advisor" shall include
                 Touchstone


                                       4
<PAGE>   5
                 Advisors, Inc. and/or any of its affiliates and the directors,
                 officers and employees of Touchstone Advisors, Inc. and/or any
                 of its affiliates.

            b)   The Trust will indemnify the Advisor against, and hold it
                 harmless from, any and all losses, claims, damages, liabilities
                 or expenses (including reasonable counsel fees and expenses)
                 resulting from acts or omissions of the Trust. Indemnification
                 shall be made only after: (i) a final decision on the merits by
                 a court or other body before whom the proceeding was brought
                 that the Trust was liable for the damages claimed or (ii) in
                 the absence of such a decision, a reasonable determination
                 based upon a review of the facts, that the Trust was liable for
                 the damages claimed, which determination shall be made by
                 either (a) the vote of a majority of a quorum of Trustees of
                 the Trust who are neither "interested persons" of the Trust nor
                 parties to the proceeding ("disinterested non-party Trustees")
                 or (b) an independent legal counsel satisfactory to the parties
                 hereto, whose determination shall be set forth in a written
                 opinion. The Advisor shall be entitled to advances from the
                 Trust for payment of the reasonable expenses incurred by it in
                 connection with the matter as to which it is seeking
                 indemnification in the manner and to the fullest extent that
                 would be permissible under the applicable provisions of the
                 General Corporation Law of Ohio. The Advisor shall provide to
                 the Trust a written affirmation of its good faith belief that
                 the standard of conduct necessary for indemnification under
                 such law has been met and a written undertaking to repay any
                 such advance if it should ultimately be determined that the
                 standard of conduct has not been met. In addition, at least one
                 of the following additional conditions shall be met: (i) the
                 Advisor shall provide security in form and amount acceptable to
                 the Trust for its undertaking; (ii) the Trust is insured
                 against losses arising by reason of the advance; or (iii) a
                 majority of a quorum of the Trustees of the Trust, the members
                 of which majority are disinterested non-party Trustees, or
                 independent legal counsel in a written opinion, shall have
                 determined, based on a review of facts readily available to the
                 Trust at the time the advance is proposed to be made, that
                 there is reason to believe that the Advisor will ultimately be
                 found to be entitled to indemnification.

         8. LIMITATION OF TRUST'S LIABILITY. The Advisor acknowledges that it
has received notice of and accepts the limitations upon the Trust's liability
set forth in its Declaration of Trust. The Advisor agrees that the Trust's
obligations hereunder in any case shall be limited to the Trust and to its
assets and that the Advisor shall not seek satisfaction of any such obligation
from the holders of the shares of any Fund nor from any Trustee, officer,
employee or agent of the Trust.


                                       5
<PAGE>   6
         9.  FORCE MAJEURE. The Advisor shall not be liable for delays or errors
occurring by reason of circumstances beyond its control, including but not
limited to acts of civil or military authority, national emergencies, work
stoppages, fire, flood, catastrophe, acts of God, insurrection, war, riot, or
failure of communication or power supply. In the event of equipment breakdowns
beyond its control, the Advisor shall take reasonable steps to minimize service
interruptions but shall have no liability with respect thereto.

         10. RENEWAL, TERMINATION AND AMENDMENT.

             a)   This Agreement shall continue in effect, unless sooner
                  terminated as hereinafter provided, for a period of twelve
                  months from the date hereof and it shall continue indefinitely
                  thereafter as to each Fund, provided that such continuance is
                  specifically approved by the parties hereto and, in addition,
                  at least annually by (i) the vote of holders of a majority of
                  the outstanding voting securities of the affected Fund or by
                  vote of a majority of the Trust's Board of Trustees and (ii)
                  by the vote of a majority of the Trustees who are not parties
                  to this Agreement or interested persons of the Advisor, cast
                  in person at a meeting called for the purpose of voting on
                  such approval.

             b)   This Agreement may be terminated at any time, with respect to
                  any Fund(s), without payment of any penalty, by the Trust's
                  Board of Trustees or by a vote of the majority of the
                  outstanding voting securities of the affected Fund(s) upon 60
                  days' prior written notice to the Advisor and by the Advisor
                  upon 60 days' prior written notice to the Trust.

             c)   This Agreement may be amended at any time by the parties
                  hereto, subject to approval by the Trust's Board of Trustees
                  and, if required by applicable SEC rules and regulations, a
                  vote of the majority of the outstanding voting securities of
                  any Fund affected by such change. This Agreement shall
                  terminate automatically in the event of its assignment.

             d)   The terms "assignment", "interested persons" and "majority of
                  the outstanding voting securities" shall have the meaning set
                  forth for such terms in the 1940 Act.

         11. SEVERABILITY. If any provision of this Agreement shall be held or
made invalid by a court decision, statute, rule or otherwise, the remainder of
this Agreement shall not be affected thereby.

         12. MISCELLANEOUS. Each party agrees to perform such further actions
and execute such further documents as are necessary to effectuate the purposes
hereof.

                         TOUCHSTONE EMERGING GROWTH FUND
                             TOUCHSTONE SERIES TRUST

         This SUB-ADVISORY AGREEMENT is made as of January 1, 1999, by and
between TOUCHSTONE ADVISORS, INC., an Ohio corporation (the "Advisor"), and
DAVID L. BABSON & COMPANY, INC., an Massachusetts corporation (the

         WHEREAS, the Advisor is an investment advisor registered under the

Series Trust (formerly Select Advisors Trust A) (the "Trust"), a Massachusetts
business trust organized pursuant to a Declaration of Trust dated February 7,

         WHEREAS, the Sub-Advisor also is an investment advisor registered under
the Investment Advisers Act of 1940, as amended; and

         WHEREAS, the Advisor desires to retain the Sub-Advisor to furnish it
with portfolio management services in connection with the Advisor's investment
advisory activities on behalf of the Fund, and the Sub-Advisor is willing to
furnish such services to the Advisor and the Fund;

         NOW THEREFORE, in consideration of the terms and conditions hereinafter
set forth, it is agreed as follows:

         1. EMPLOYMENT OF THE SUB-ADVISOR. In accordance with and subject to the
Investment Advisory Agreement between the Trust and the Advisor, attached hereto
as Exhibit A (the "Advisory Agreement"), the Advisor hereby appoints the
Sub-Advisor to manage the investment and reinvestment of that portion of the
assets of the Fund allocated to it by the Advisor (which portion, until changed
by the Advisor by not less than ten days prior written notice, shall be 50% of
the total assets of the Fund) (the said portion, as it may be changed from time
to time, being herein called the "Fund Assets"), subject to the control and
direction of the Advisor and the Trust's Board of Trustees, for the period and
on the terms hereinafter set forth. The Sub-Advisor hereby accepts such
employment and agrees during such period to render the services and to perform
the duties called for by this Agreement for the compensation herein provided.
The Sub-Advisor shall at all times maintain its registration as an investment
advisor under the Investment Advisers Act of 1940 and shall otherwise comply in
all material respects with all applicable laws
<PAGE>   2
and regulations, both state and federal. The Sub-Advisor shall for all purposes
herein be deemed an independent contractor and shall, except as expressly
provided or authorized (whether herein or otherwise), have no authority to act
for or represent the Trust in any way or otherwise be deemed an agent of the
Trust or the Fund.

         2. DUTIES OF THE SUB-ADVISOR. The Sub-Advisor will provide the
following services and undertake the following duties:

            a. The Sub-Advisor will manage the investment and reinvestment of
         the assets of the Fund, subject to and in accordance with the
         investment objectives, policies and restrictions of the Fund and any
         directions which the Advisor or the Trust's Board of Trustees may give
         from time to time with respect to the Fund. In furtherance of the
         foregoing, the Sub-Advisor will make all determinations with respect to
         the investment of the Fund Assets and the purchase and sale of
         portfolio securities and shall take such steps as may be necessary or
         advisable to implement the same. The Sub-Advisor also will determine
         the manner in which voting rights, rights to consent to corporate
         action and any other rights pertaining to the portfolio securities will
         be exercised. The Sub-Advisor will render regular reports to the
         Trust's Board of Trustees, to the Advisor and to BARRA RogersCasey,
         Inc. (or such other advisor or advisors as the Advisor shall engage to
         assist it in the evaluation of the performance and activities of the
         Sub-Advisor). Such reports shall be made in such form and manner and
         with respect to such matters regarding the Fund and the Sub-Advisor as
         the Trust, the Advisor or BARRA RogersCasey, Inc. shall from time to
         time request; provided, however, that in the absence of extraordinary
         circumstances, the individual primarily responsible for management of
         Fund Assets for the Sub-Advisor will not be required to attend in
         person more than one meeting per year with the trustees of the Trust.

            b. The Sub-Advisor shall provide support to the Advisor with respect
         to the marketing of the Fund, including but not limited to: (i)
         permission to use the Sub-Advisor's name as provided in Section 5, (ii)
         permission to use the past performance and investment history of the
         Sub-Advisor with respect to a composite of other funds managed by the
         Sub-Advisor that are comparable, in investment objective and
         composition, to the Fund, and (iii) access to the individual(s)
         responsible for day-to-day management of the Fund for marketing
         conferences, teleconferences and other activities involving the
         promotion of the Fund, subject to the reasonable request of the
         Advisor, (iv) permission to use biographical and historical data of the
         Sub-Advisor and individual manager(s), and (v) permission to use the
         names of those clients pre-approved by the Sub-Advisor to which the
         Sub-Advisor provides investment management


                                     - 2 -
<PAGE>   3
         services, subject to receipt of the consent of such clients to the use
         of their names.

            c. The Sub-Advisor will, in the name of the Fund, place orders for
         the execution of all portfolio transactions in accordance with the
         policies with respect thereto set forth in the Trust's registration
         statements under the 1940 Act and the Securities Act of 1933, as such
         registration statements may be in effect from time to time. In
         connection with the placement of orders for the execution of portfolio
         transactions, the Sub-Advisor will create and maintain all necessary
         brokerage records of the Fund in accordance with all applicable laws,
         rules and regulations, including but not limited to records required by
         Section 31(a) of the 1940 Act. All records shall be the property of the
         Trust and shall be available for inspection and use by the Securities
         and Exchange Commission (the "SEC"), the Trust or any person retained
         by the Trust. Where applicable, such records shall be maintained by the
         Advisor for the periods and in the places required by Rule 31a-2 under
         the 1940 Act. When placing orders with brokers and dealers, the
         Sub-Advisor's primary objective shall be to obtain the most favorable
         price and execution available for the Fund, and in placing such orders
         the Sub-Advisor may consider a number of factors, including, without
         limitation, the overall direct net economic result to the Fund
         (including commissions, which may not be the lowest available but
         ordinarily should not be higher than the generally prevailing
         competitive range), the financial strength and stability of the broker,
         the efficiency with which the transaction will be effected, the ability
         to effect the transaction at all where a large block is involved and
         the availability of the broker or dealer to stand ready to execute
         possibly difficult transactions in the future. The Sub-Advisor is
         specifically authorized, to the extent authorized by law (including,
         without limitation, Section 28(e) of the Securities Exchange Act of
         1934, as amended (the "Exchange Act"), to pay a broker or dealer who
         provides research services to the Sub-Advisor an amount of commission
         for effecting a portfolio transaction in excess of the amount of
         commission another broker or dealer would have charged for effecting
         such transaction, in recognition of such additional research services
         rendered by the broker or dealer, but only if the Sub-Advisor
         determines in good faith that the excess commission is reasonable in
         relation to the value of the brokerage and research services provided
         by such broker or dealer viewed in terms of the particular transaction
         or the Sub-Advisor's overall responsibilities with respect to
         discretionary accounts that it manages, and that the Fund derives or
         will derive a reasonably significant benefit from such research
         services. The Sub-Advisor will present a written report to the Board of
         Trustees of the Trust, at least quarterly, indicating total brokerage
         expenses, actual or imputed, as well as the services obtained in
         consideration for such expenses, broken down by broker-dealer and


                                     - 3 -
<PAGE>   4
         containing such information as the Board of Trustees reasonably shall
         request.

            d. In the event of any reorganization or other change in the
         Sub-Advisor, its investment principals, supervisors or members of its
         investment (or comparable) committee, the Sub-Advisor shall give the
         Advisor and the Trust's Board of Trustees written notice of such
         reorganization or change within a reasonable time (but not later than
         30 days) after such reorganization or change.

            e. The Sub-Advisor will bear its expenses of providing services to
         the Fund pursuant to this Agreement except such expenses as are
         undertaken by the Advisor or the Trust.

            f. The Sub-Advisor will manage the Fund Assets and the investment
         and reinvestment of such assets so as to comply with the provisions of
         the 1940 Act and with Subchapter M of the Internal Revenue Code of
         1986, as amended.

         3. COMPENSATION OF THE SUB-ADVISOR.

            a. As compensation for the services to be rendered and duties
         undertaken hereunder by the Sub-Advisor, the Advisor will pay to the
         Sub-Advisor a monthly fee equal on an annual basis to 0.50% of the
         average daily net Fund Assets. Such fee shall be computed and accrued
         daily. If the Sub-Advisor serves in such capacity for less than the
         whole of any period specified in this Section 3a, the compensation to
         the Sub-Advisor shall be prorated. For purposes of calculating the
         Sub-Advisor's fee, the daily value of the Fund Assets shall be computed
         by the same method as the Trust uses to compute the net asset value of
         the Fund for purposes of purchases and redemptions of interests
         thereof.

            b. The Sub-Advisor reserves the right to waive all or a part of its
         fees hereunder.

         4. ACTIVITIES OF THE SUB-ADVISOR. It is understood that the Sub-Advisor
may perform investment advisory services for various other clients, including
other investment companies. The Sub-Advisor will report to the Board of Trustees
of the Trust (at regular quarterly meetings and at such other times as such
Board of Trustees reasonably shall request, subject to the limitation on
personal attendance at such meetings set forth in Section 2a) (i) the financial
condition and prospects of the Sub-Advisor, (ii) the nature and amount of
transactions affecting the Fund that involve the Sub-Advisor and affiliates of
the Sub-Advisor, (iii) information regarding any potential conflicts of interest
arising by reason of its continuing provision of


                                     - 4 -
<PAGE>   5
advisory services to the Fund and to its other accounts, and (iv) such other
information as the Board of Trustees shall reasonably request regarding the
Fund, the Fund's performance, the services provided by the Sub-Advisor to the
Fund as compared to its other accounts and the plans of, and the capability of,
the Sub-Advisor with respect to providing future services to the Fund and its
other accounts. The Sub-Advisor agrees to submit to the Trust a statement
defining its policies with respect to the allocation of business among the Fund
and its other clients.

         It is understood that the Sub-Advisor may become interested in the
Trust as an interest holder or otherwise.

         The Sub-Advisor has supplied to the Advisor and the Trust copies of its
Form ADV with all exhibits and attachments thereto and will hereafter supply to
the Advisor, promptly upon the preparation thereof, copies of all amendments or
restatements of such document.

         5. USE OF NAMES. Neither the Advisor nor the Trust shall use the name
of the Sub-Advisor in any prospectus, sales literature or other material
relating to the Advisor or the Trust in any manner not approved in advance by
the Sub-Advisor; provided, however, that the Sub-Advisor will approve all uses
of its name which merely refer in accurate terms to its appointment hereunder or
which are required by the SEC or a state securities commission; and provided
further, that in no event shall such approval be unreasonably withheld. The
Sub-Advisor shall not use the name of the Advisor or the Trust in any material
relating to the Sub-Advisor in any manner not approved in advance by the Advisor
or the Trust, as the case may be; provided, however, that the Advisor and the
Trust shall each approve all uses of their respective names which merely refer
in accurate terms to the appointment of the Sub-Advisor hereunder or which are
required by the SEC or a state securities commission; and, provided further,
that in no event shall such approval be unreasonably withheld.

         6. LIMITATION OF LIABILITY OF THE SUB-ADVISOR. Absent willful
misfeasance, bad faith, gross negligence, or reckless disregard of obligations
or duties hereunder on the part of the Sub-Advisor, the Sub-Advisor shall not be
subject to liability to the Advisor, the Trust or to any holder of an interest
in the Fund for any act or omission in the course of, or connected with,
rendering services hereunder or for any losses that may be sustained in the
purchase, holding or sale of any security. As used in this Section 6, the term
"Sub-Advisor" shall include the Sub-Advisor and/or any of its affiliates and the
directors, officers and employees of the Sub-Advisor and/or any of its
affiliates.

         7. LIMITATION OF TRUST'S LIABILITY. The Sub-Advisor acknowledges that
it has received notice of and accepts the limitations upon the Trust's liability
set forth


                                     - 5 -
<PAGE>   6
in its Declaration of Trust. The Sub-Advisor agrees that (i) the Trust's
obligations to the Sub-Advisor under this Agreement (or indirectly under the
Advisory Agreement) shall be limited, in any event to the assets of the Fund and
(ii) the Sub-Advisor shall not seek satisfaction of any such obligation from the
holders of shares of the Fund nor from any Trustee, officer, employee or agent
of the Trust.

         8. FORCE MAJEURE. The Sub-Advisor shall not be liable for delays or
errors occurring by reason of circumstances beyond its control, including but
not limited to acts of civil or military authority, national emergencies, work
stoppages, fire, flood, catastrophe, acts of God, insurrection, war, riot, or
failure of communication or power supply. In the event of equipment breakdowns
beyond its control, the Sub-Advisor shall take reasonable steps to minimize
service interruptions but shall have no liability with respect thereto.

         9. RENEWAL, TERMINATION AND AMENDMENT.

            a. This Agreement shall continue in effect, unless sooner terminated
         as hereinafter provided, until December 31, 1999; and it shall continue
         thereafter provided that such continuance is specifically approved by
         the parties and, in addition, at least annually by (i) the vote of the
         holders of a majority of the outstanding voting securities (as herein
         defined) of the Fund or by vote of a majority of the Trust's Board of
         Trustees and (ii) by the vote of a majority of the Trustees who are not
         parties to this Agreement or interested persons of either the Advisor
         or the Sub-Advisor, cast in person at a meeting called for the purpose
         of voting on such approval.

            b. This Agreement may be terminated at any time, without payment of
         any penalty, (i) by the Advisor, by the Trust's Board of Trustees or by
         a vote of the majority of the outstanding voting securities of the
         Fund, in any such case upon not less than 60 days' prior written notice
         to the Sub-Advisor and (ii) by the Sub-Advisor upon not less than 60
         days' prior written notice to the Advisor and the Trust. This Agreement
         shall terminate automatically in the event of its assignment.

            c. This Agreement may be amended at any time by the parties hereto,
         subject to approval by the Trust's Board of Trustees and, if required
         by applicable SEC rules and regulations, a vote of the majority of the
         outstanding voting securities of the Fund affected by such change.

            d. The terms "assignment," "interested persons" and "majority of the
         outstanding voting securities" shall have the meaning set forth for
         such terms in the 1940 Act.

         WHEREAS, the Advisor is an investment advisor registered under the

furnish such services to the Advisor and the Fund;

         NOW THEREFORE, in consideration of the terms and conditions hereinafter

         the execution of all portfolio transactions in accordance with the
         policies with respect thereto set forth in the Trust's registration
         statements under the 1940 Act and the Securities Act of 1933, as such

         with all applicable laws, rules and regulations, including but not
         limited to records required by Section 31(a) of the 1940 Act. All
         records shall be the property of the Trust and shall be available for
         inspection and use by the Securities and Exchange Commission (the
         "SEC"), the Trust or any person retained by the Trust. Where
         applicable, such records shall be maintained by the Advisor for the
         periods and in the places required by Rule 31a-2 under the 1940 Act.
         When placing orders with brokers and dealers, the Sub-Advisor's primary
         objective shall be to obtain the most favorable price and execution
         available for the Fund, and in placing such orders the Sub-Advisor may
         consider a number of factors, including, without limitation, the
         overall direct net economic result to the Fund (including commissions,
         which may not be the lowest available but ordinarily should not be
         higher than the generally prevailing competitive range), the financial
         strength and stability of the broker, the efficiency with which the
         transaction will be effected, the ability to effect the transaction at
         all where a large block is involved and the availability of the broker
         or dealer to stand ready to execute possibly difficult transactions in
         the future. The Sub-Advisor is specifically authorized, to the extent
         authorized by law (including, without limitation, Section 28(e) of the
         Securities Exchange Act of 1934, as amended (the "Exchange Act"), to
         pay a broker or dealer who provides research services to the
         Sub-Advisor an amount of commission for effecting a portfolio
         transaction in excess of the amount of commission another broker or
         dealer would have charged for effecting such transaction, in
         recognition of such additional research services rendered by the broker
         or dealer, but only if the Sub-Advisor determines in good faith that
         the excess commission is reasonable in relation to the value of the
         brokerage and research services provided by such broker or dealer
         viewed in terms of the particular transaction or the Sub-Advisor's
         overall responsibilities with respect to discretionary accounts that it
         manages, and that the Fund derives or will derive a reasonably
         significant benefit from such research services. The Sub-Advisor will
         present a written report to the Board of Trustees of the Trust, at
         least quarterly, indicating total brokerage expenses, actual or
         imputed, as well as the services obtained in consideration for such
         expenses, broken down by broker-dealer and containing such information
         as the Board of Trustees reasonably shall request.

            d. In the event of any reorganization or other change in the
         Sub-Advisor, its investment principals, supervisors or members of its
         investment (or comparable) committee, the Sub-Advisor shall give the
         Advisor and the Trust's Board of Trustees written notice of such
         reorganization or change within a reasonable time (but not later than
         30 days) after such reorganization or change.

            e. The Sub-Advisor will bear its expenses of providing services to
         the Fund pursuant to this Agreement except such expenses as are
         undertaken by the Advisor or the Trust.

            f. The Sub-Advisor will manage the Fund Assets and the investment
         and reinvestment of such assets so as to comply with the provisions of
         the 1940 Act and with Subchapter M of the Internal Revenue Code of
         1986, as amended.

         3. COMPENSATION OF THE SUB-ADVISOR.

            a. As compensation for the services to be rendered and duties
         undertaken hereunder by the Sub-Advisor, the Advisor will pay to the
         Sub-Advisor a monthly fee equal on an annual basis to 0.45% of the
         first $10 million of the average daily net assets of the Fund managed
         by the Sub-Advisor, 0.40% of the average daily net assets of the Fund
         managed by the Sub-Advisor in excess of $10 million and up to $50
         million and 0.35% of the average daily net assets of the Fund managed
         by the Sub-Advisor in excess of $50 million. Such fee shall be computed
         and accrued daily. If the Sub-Advisor serves in such capacity for less
         than the whole of any period specified in this Section 3a, the
         compensation to the Sub-Advisor shall be prorated. For purposes of
         calculating the Sub-Advisor's fee, the daily value of the Fund's net
         assets shall be computed by the same method as the Trust uses to
         compute the net asset value of the Fund for purposes of purchases and
         redemptions of interests thereof.

            b. The Sub-Advisor reserves the right to waive all or a part of its
         fees hereunder.

         4. ACTIVITIES OF THE SUB-ADVISOR. It is understood that the Sub-Advisor
may perform investment advisory services for various other clients, including
other investment companies. The Sub-Advisor will report to the Board of Trustees
of the Trust (at regular quarterly meetings and at such other times as such
Board of Trustees reasonably shall request) (i) the financial condition and
prospects of the Sub-Advisor, (ii) the nature and amount of transactions
affecting the Fund that involve the Sub-Advisor and affiliates of the
Sub-Advisor, (iii) information regarding any potential conflicts of interest
arising by reason of its continuing provision of advisory services to the Fund
and to its other accounts, and (iv) such other information as the Board of
Trustees shall reasonably request regarding the Fund, the Fund's performance,
the services provided by the Sub-Advisor to the Fund as compared to its other
accounts and the plans of, and the capability of, the Sub-Advisor with respect
to providing future services to the Fund and its other accounts. At least
annually, the Sub-Advisor will provide to the Trustees information regarding the
composite return of such of its other accounts as are


                                     - 4 -
<PAGE>   5
comparable, in investment objective and composition, to the Fund. The
Sub-Advisor agrees to submit to the Trust a statement defining its policies with
respect to the allocation of investment opportunities among the Fund and its
other clients.

         It is understood that the Sub-Advisor may become interested in the
Trust as an interest holder or otherwise.

         The Sub-Advisor has supplied to the Advisor and the Trust copies of its
Form ADV with all exhibits and attachments thereto (including the Sub-Advisor's
statement of financial condition) and will hereafter supply to the Advisor,
promptly upon the preparation thereof, copies of all amendments or restatements
of such document.

         5. USE OF NAMES. Neither the Advisor nor the Trust shall use the name
of the Sub-Advisor in any prospectus, sales literature or other material
relating to the Advisor or the Trust in any manner not approved in advance by
the Sub-Advisor; provided, however, that the Sub-Advisor will approve all uses
of its name which merely refer in accurate terms to its appointment hereunder or
which are required by the SEC or a state securities commission; and provided
further, that in no event shall such approval be unreasonably withheld. The
Sub-Advisor shall not use the name of the Advisor or the Trust in any material
relating to the Sub-Advisor in any manner not approved in advance by the Advisor
or the Trust, as the case may be; provided, however, that the Advisor and the
Trust shall each approve all uses of their respective names which merely refer
in accurate terms to the appointment of the Sub-Advisor hereunder or which are
required by the SEC or a state securities commission; and, provided further,
that in no event shall such approval be unreasonably withheld.

         6. LIMITATION OF LIABILITY OF THE SUB-ADVISOR. Absent willful
misfeasance, bad faith, gross negligence, or reckless disregard of obligations
or duties hereunder on the part of the Sub-Advisor, the Sub-Advisor shall not be
subject to liability to the Advisor, the Trust or to any holder of an interest
in the Fund for any act or omission in the course of, or connected with,
rendering services hereunder or for any losses that may be sustained in the
purchase, holding or sale of any security. As used in this Section 6, the term
"Sub-Advisor" shall include the Sub-Advisor and/or any of its affiliates and the
directors, officers and employees of the Sub-Advisor and/or any of its
affiliates.

         7. LIMITATION OF TRUST'S LIABILITY. The Sub-Advisor acknowledges that
it has received notice of and accepts the limitations upon the Trust's liability
set forth in its Declaration of Trust. The Sub-Advisor agrees that (i) the
Trust's obligations to the Sub-Advisor under this Agreement (or indirectly under
the Advisory Agreement) shall be limited, in any event to the assets of the Fund
and (ii) the Sub-


                                     - 5 -
<PAGE>   6
Advisor shall not seek satisfaction of any such obligation from the holders of
shares of the Fund nor from any Trustee, officer, employee or agent of the
Trust.

         8.  FORCE MAJEURE. The Sub-Advisor shall not be liable for delays or
errors occurring by reason of circumstances beyond its control, including but
not limited to acts of civil or military authority, national emergencies, work
stoppages, fire, flood, catastrophe, acts of God, insurrection, war, riot, or
failure of communication or power supply. In the event of equipment breakdowns
beyond its control, the Sub-Advisor shall take reasonable steps to minimize
service interruptions but shall have no liability with respect thereto.

         9.  RENEWAL, TERMINATION AND AMENDMENT.

             a. This Agreement shall continue in effect, unless sooner
         terminated as hereinafter provided, until December 31, 1999; and it
         shall continue thereafter provided that such continuance is
         specifically approved by the parties and, in addition, at least
         annually by (i) the vote of the holders of a majority of the
         outstanding voting securities (as herein defined) of the Fund or by
         vote of a majority of the Trust's Board of Trustees and (ii) by the
         vote of a majority of the Trustees who are not parties to this
         Agreement or interested persons of either the Advisor or the
         Sub-Advisor, cast in person at a meeting called for the purpose of
         voting on such approval.

             b. This Agreement may be terminated at any time, without payment of
         any penalty, (i) by the Advisor, by the Trust's Board of Trustees or by
         a vote of the majority of the outstanding voting securities of the
         Fund, in any such case upon not less than 60 days' prior written notice
         to the Sub-Advisor and (ii) by the Sub-Advisor upon not less than 60
         days' prior written notice to the Advisor and the Trust. This Agreement
         shall terminate automatically in the event of its assignment.

             c. This Agreement may be amended at any time by the parties hereto,
         subject to approval by the Trust's Board of Trustees and, if required
         by applicable SEC rules and regulations, a vote of the majority of the
         outstanding voting securities of the Fund affected by such change.

             d. The terms "assignment," "interested persons" and "majority of
         the outstanding voting securities" shall have the meaning set forth for
         such terms in the 1940 Act.

         10. SEVERABILITY. If any provision of this Agreement shall become or
shall be found to be invalid by a court decision, statute, rule or otherwise,
the remainder of this Agreement shall not be affected thereby.

                             SUB-ADVISORY AGREEMENT

                      TOUCHSTONE INTERNATIONAL EQUITY FUND
                             TOUCHSTONE SERIES TRUST

         This SUB-ADVISORY AGREEMENT is made as of January 1, 1999, by and
between TOUCHSTONE ADVISORS, INC., an Ohio corporation (the "Advisor"), and BEA
ASSOCIATES, an New York general partnership (the "Sub-Advisor").

         WHEREAS, the Advisor is an investment advisor registered under the
Investment Advisers Act of 1940, as amended, and has been retained by Touchstone
Series Trust (formerly Select Advisors Trust A) (the "Trust"), a Massachusetts
business trust organized pursuant to a Declaration of Trust dated February 7,
1994 and registered as an open-end diversified management investment company
under the Investment Company Act of 1940 (the "1940 Act") to provide investment
advisory services to the Touchstone International Equity Fund (the "Fund"); and

         WHEREAS, the Sub-Advisor also is an investment advisor registered under
the Investment Advisers Act of 1940, as amended; and

         WHEREAS, the Advisor desires to retain the Sub-Advisor to furnish it
with portfolio management services in connection with the Advisor's investment
advisory activities on behalf of the Fund, and the Sub-Advisor is willing to
furnish such services to the Advisor and the Fund;

         NOW THEREFORE, in consideration of the terms and conditions hereinafter
set forth, it is agreed as follows:

         1. EMPLOYMENT OF THE SUB-ADVISOR. In accordance with and subject to the
Investment Advisory Agreement between the Trust and the Advisor, attached hereto
as Exhibit A (the "Advisory Agreement"), the Advisor hereby appoints the
Sub-Advisor to manage the investment and reinvestment of those assets of the
Fund allocated to it by the Advisor (the "Fund Assets"), subject to the control
and direction of the Advisor and the Trust's Board of Trustees, for the period
and on the terms hereinafter set forth. The Sub-Advisor hereby accepts such
employment and agrees during such period to render the services and to perform
the duties called for by this Agreement for the compensation herein provided.
The Sub-Advisor shall at all times maintain its registration as an investment
advisor under the Investment Advisers Act of 1940 and shall otherwise comply in
all material respects with all applicable laws and regulations, both state and
federal. The Sub-Advisor shall for all purposes herein be deemed an independent
contractor and shall, except as expressly provided or authorized (whether herein
or otherwise),
<PAGE>   2
have no authority to act for or represent the Trust in any way or otherwise be
deemed an agent of the Trust or the Fund.

         2. DUTIES OF THE SUB-ADVISOR. The Sub-Advisor will provide the
following services and undertake the following duties:

            a. The Sub-Advisor will manage the investment and reinvestment of
         the assets of the Fund, subject to and in accordance with the
         investment objectives, policies and restrictions of the Fund and any
         directions which the Advisor or the Trust's Board of Trustees may give
         from time to time with respect to the Fund. In furtherance of the
         foregoing, the Sub-Advisor will make all determinations with respect to
         the investment of the assets of the Fund and the purchase and sale of
         portfolio securities and shall take such steps as may be necessary or
         advisable to implement the same. The Sub-Advisor also will determine
         the manner in which voting rights, rights to consent to corporate
         action and any other rights pertaining to the portfolio securities will
         be exercised. The Sub-Advisor will render regular reports to the
         Trust's Board of Trustees, to the Advisor and to BARRA RogersCasey,
         Inc. (or such other advisor or advisors as the Advisor shall engage to
         assist it in the evaluation of the performance and activities of the
         Sub-Advisor). Such reports shall be made in such form and manner and
         with respect to such matters regarding the Fund and the Sub-Advisor as
         the Trust, the Advisor or BARRA RogersCasey, Inc. shall from time to
         time reasonably request.

            b. The Sub-Advisor shall provide support to the Advisor with respect
         to the marketing of the Fund, consisting of: (i) permission to use the
         Sub-Advisor's name as provided in Section 5, (ii) permission to use the
         past performance and investment history of the Sub-Advisor as the same
         is applicable to the Fund, and (iii) access to the individual(s)
         responsible for the management of the Fund for marketing conferences,
         teleconferences and other activities involving the promotion of the
         Fund, subject to the reasonable request of the Advisor and to the
         limitation that the individual primarily responsible for management of
         the Fund Assets for the Sub-Advisor will not be required to attend more
         than one meeting of the Trust's Trustees in any one year, (iv)
         permission to use biographical and historical data of the Sub-Advisor
         and individual manager(s), and (v) permission to use the names of
         clients to which the Sub-Advisor provides investment management
         services, subject to any restrictions imposed by clients on the use of
         such names.

            c. The Sub-Advisor will, in the name of the Fund, place orders for
         the execution of all portfolio transactions in accordance with the
         policies with respect thereto set forth in the Trust's registration
         statements under the 1940 Act and the Securities Act of 1933, as such
         registration statements


                                     - 2 -
<PAGE>   3
         may be in effect from time to time. In connection with the placement of
         orders for the execution of portfolio transactions, the Sub-Advisor
         will create and maintain all necessary brokerage records of the Fund in
         accordance with all applicable laws, rules and regulations, including
         but not limited to records required by Section 31(a) of the 1940 Act.
         All records shall be the property of the Trust and shall be available
         for inspection and use by the Securities and Exchange Commission (the
         "SEC"), the Trust or any person retained by the Trust. Where
         applicable, such records shall be maintained by the Advisor for the
         periods and in the places required by Rule 31a-2 under the 1940 Act.
         When placing orders with brokers and dealers, the Sub-Advisor's primary
         objective shall be to obtain the most favorable price and execution
         available for the Fund, and in placing such orders the Sub-Advisor may
         consider a number of factors, including, without limitation, the
         overall direct net economic result to the Fund (including commissions,
         which may not be the lowest available but ordinarily should not be
         higher than the generally prevailing competitive range), the financial
         strength and stability of the broker, the efficiency with which the
         transaction will be effected, the ability to effect the transaction at
         all where a large block is involved and the availability of the broker
         or dealer to stand ready to execute possibly difficult transactions in
         the future. The Sub-Advisor is specifically authorized, to the extent
         authorized by law (including, without limitation, Section 28(e) of the
         Securities Exchange Act of 1934, as amended (the "Exchange Act"), to
         pay a broker or dealer who provides research services to the
         Sub-Advisor an amount of commission for effecting a portfolio
         transaction in excess of the amount of commission another broker or
         dealer would have charged for effecting such transaction, in
         recognition of such additional research services rendered by the broker
         or dealer, but only if the Sub-Advisor determines in good faith that
         the excess commission is reasonable in relation to the value of the
         brokerage and research services provided by such broker or dealer
         viewed in terms of the particular transaction or the Sub-Advisor's
         overall responsibilities with respect to discretionary accounts that it
         manages. The Sub-Advisor will present a written report to the Board of
         Trustees of the Trust, at least quarterly, indicating total brokerage
         expenses, actual or imputed, as well as the services obtained in
         consideration for such expenses, broken down by broker-dealer and
         containing such information as the Board of Trustees reasonably shall
         request.

            d. In the event of any reorganization or other change in the
         Sub-Advisor, its investment principals, supervisors or members of its
         investment (or comparable) committee, the Sub-Advisor shall give the
         Advisor and the Trust's Board of Trustees written notice of such
         reorganization or change within a reasonable time (but not later than
         30 days) after such reorganization or change. In addition, the
         Sub-Advisor will notify the Advisor


                                     - 3 -
<PAGE>   4
         of any change in the membership of the Sub-Advisor within a reasonable
         time (but not more than 30 days) after such change takes place.

            e. The Sub-Advisor will bear its expenses of providing services to
         the Fund pursuant to this Agreement except such expenses as are
         undertaken by the Advisor or the Trust.

            f. Based on account information regarding the Fund provided by the
         Advisor, the Sub-Advisor will manage the Fund Assets and the investment
         and reinvestment of such assets so as to comply with the provisions of
         the 1940 Act and with Subchapter M of the Internal Revenue Code of
         1986, as amended; provided, however, that with respect to the
         provisions of the 1940 Act regarding transactions with affiliates, the
         obligations of the Sub-Advisor shall be limited to matters involving
         its own affiliates and such other persons as the Advisor shall
         expressly identify as affiliated persons.

         3. COMPENSATION OF THE SUB-ADVISOR.

            a. As compensation for the services to be rendered and duties
         undertaken hereunder by the Sub-Advisor, the Advisor will pay to the
         Sub-Advisor a monthly fee equal on an annual basis to 0.85% of the
         first $30 million of the average daily net assets of the Fund, 0.80% of
         the average daily net assets of the Fund in excess of $30 million and
         up to $50 million, 0.60% of the average daily net assets of the Fund in
         excess of $50 million and up to $75 million, and 0.50% of the average
         daily net assets of the Fund in excess of $75 million. Such fee shall
         be computed and accrued daily. If the Sub-Advisor serves in such
         capacity for less than the whole of any period specified in this
         Section 3a, the compensation to the Sub-Advisor shall be prorated. For
         purposes of calculating the Sub-Advisor's fee, the daily value of the
         Fund's net assets shall be computed by the same method as the Trust
         uses to compute the net asset value of the Fund for purposes of
         purchases and redemptions of interests thereof.

            b. The Sub-Advisor reserves the right to waive all or a part of its
         fees hereunder.

         4. ACTIVITIES OF THE SUB-ADVISOR. It is understood that the Sub-Advisor
may perform investment advisory services for various other clients, including
other investment companies. The Sub-Advisor will report to the Board of Trustees
of the Trust (at regular quarterly meetings and at such other times as such
Board of Trustees reasonably shall request) information reasonably requested by
such Board of Trustees regarding (i) the nature and amount of transactions
affecting the Fund

that involve the Sub-Advisor and affiliates of the Sub-Advisor, (ii) any
potential conflicts of interest arising by reason of its continuing provision of
advisory services to the Fund and to its other accounts, and (iii) such other
matters as the Board of Trustees shall reasonably request regarding the Fund,
the Fund's performance, the services provided by the Sub-Advisor to the Fund as
compared to its other accounts and the plans of, and the capability of, the
Sub-Advisor with respect to providing future services to the Fund and its other
accounts. The Sub-Advisor agrees to submit to the Trust a statement defining its
policies with respect to the allocation of business among the Fund and its other
clients.

         It is understood that the Sub-Advisor may become interested in the
Trust as an interest holder or otherwise.

         The Sub-Advisor has supplied to the Advisor and the Trust copies of its
Form ADV with all exhibits and attachments thereto (including the Sub-Advisor's
statement of financial condition) and will hereafter supply to the Advisor,
promptly upon the preparation thereof, copies of all amendments or restatements
of such document.

         5. USE OF NAMES. Neither the Advisor nor the Trust shall use the name
of the Sub-Advisor in any prospectus, sales literature or other material
relating to the Advisor or the Trust in any manner not approved in advance by
the Sub-Advisor; provided, however, that the Sub-Advisor will approve all uses
of its name which merely refer in accurate terms to its appointment hereunder or
which are required by the SEC or a state securities commission; and provided
further, that in no event shall such approval be unreasonably withheld. The
Sub-Advisor shall not use the name of the Advisor or the Trust in any material
relating to the Sub-Advisor in any manner not approved in advance by the Advisor
or the Trust, as the case may be; provided, however, that the Advisor and the
Trust shall each approve all uses of their respective names which merely refer
in accurate terms to the appointment of the Sub-Advisor hereunder or which are
required by the SEC or a state securities commission; and, provided further,
that in no event shall such approval be unreasonably withheld.

         6. LIMITATION OF LIABILITY OF THE SUB-ADVISOR.

            a. Absent willful misfeasance, bad faith, gross negligence, or
reckless disregard of obligations or duties hereunder on the part of the
Sub-Advisor, the Sub-Advisor shall not be subject to liability to the Advisor,
the Trust or to any holder of an interest in the Fund for any act or omission in
the course of, or connected with, rendering services hereunder or for any losses
that may be sustained in the purchase, holding or sale of any security. As used
in this Section 6, the term "Sub-Advisor" shall include the Sub-Advisor and/or
any of its


                                     - 5 -
<PAGE>   6
affiliates and the directors, officers and employees of the Sub-Advisor and/or
any of its affiliates.

            b. The Trust or the Advisor will indemnify the Sub-Advisor against,
and hold it harmless from, any and all losses, claims, damages, liabilities or
expenses (including reasonable counsel fees and expenses) resulting from its
activities under and pursuant to this Agreement, except to the extent that such
losses, claims, damages, liabilities or expenses result from the gross
negligence, bad faith or willful misfeasance of the Sub-Advisor or from a breach
of its obligations or duties hereunder. Indemnification shall be made only
after: (i) a final decision on the merits by a court or other body before whom
the proceeding was brought that the Trust or Advisor was liable for the damages
claimed or (ii) in the absence of such a decision, a reasonable determination
based upon a review of the facts, that the Trust or the Advisor was liable for
the damages claimed, which determination shall be made by either (a) the vote of
a majority of a quorum of Trustees of the Trust who are neither "interested
persons" of the Trust nor parties to the proceeding ("disinterested non-party
Trustees") or (b) an independent legal counsel satisfactory to the parties
hereto, whose determination shall be set forth in a written opinion. The
Sub-Advisor shall be entitled to advances from the Trust for payment of the
reasonable expense incurred by it in connection with the matter as to which it
is seeking indemnification in the manner and to the fullest extent that would be
permissible under the applicable provisions of the General Corporation Law of
Ohio. The Sub-Advisor shall provide to the Trust a written affirmation of its
good faith belief that the standard of conduct necessary for indemnification
under such law has been met and a written undertaking to repay any such advance
if it should ultimately be determined that the standard of conduct was not met.
In addition, at least one of the following additional conditions shall be met:
(a) the Sub-Advisor shall provide security in form and amount acceptable to the
Trust for its undertaking; (b) the Trust is insured against losses arising by
reason of the advance; or (c) a majority of a quorum of the Trustees of the
Trust, the members of which majority are disinterested non-party Trustees, or
independent legal counsel in written opinion, shall have determined, based on a
review of facts readily available to the Trust at the time of the advance is
proposed to be made, that there is reason to believe that the Sub-Advisor will
ultimately be found to be entitled to indemnification.

         7. LIMITATION OF TRUST'S LIABILITY. The Sub-Advisor acknowledges that
it has received notice of and accepts the limitations upon the Trust's liability
set forth in its Declaration of Trust. The Sub-Advisor agrees that (i) the
Trust's obligations to the Sub-Advisor under this Agreement (or indirectly under
the Advisory Agreement) shall be limited, in any event to the assets of the Fund
and (ii) the Sub-Advisor shall not seek satisfaction of any such obligation from
the holders of shares of the Fund nor from any Trustee, officer, employee or
agent of the Trust.


                                     - 6 -
<PAGE>   7
         8.  FORCE MAJEURE. The Sub-Advisor shall not be liable for delays or
errors occurring by reason of circumstances beyond its control, including but
not limited to acts of civil or military authority, national emergencies, work
stoppages, fire, flood, catastrophe, acts of God, insurrection, war, riot, or
failure of communication or power supply. In the event of equipment breakdowns
beyond its control, the Sub-Advisor shall take reasonable steps to minimize
service interruptions but shall have no liability with respect thereto.

         9.  RENEWAL, TERMINATION AND AMENDMENT.

             a. This Agreement shall continue in effect, unless sooner
         terminated as hereinafter provided, until December 31, 1999; and it
         shall continue thereafter provided that such continuance is
         specifically approved by the parties and, in addition, at least
         annually by (i) the vote of the holders of a majority of the
         outstanding voting securities (as herein defined) of the Fund or by
         vote of a majority of the Trust's Board of Trustees and (ii) by the
         vote of a majority of the Trustees who are not parties to this
         Agreement or interested persons of either the Advisor or the
         Sub-Advisor, cast in person at a meeting called for the purpose of
         voting on such approval.

             b. This Agreement may be terminated at any time, without payment of
         any penalty, (i) by the Advisor, by the Trust's Board of Trustees or by
         a vote of the majority of the outstanding voting securities of the
         Fund, in any such case upon not less than 60 days' prior written notice
         to the Sub-Advisor and (ii) by the Sub-Advisor upon not less than 60
         days' prior written notice to the Advisor and the Trust. This Agreement
         shall terminate automatically in the event of its assignment.

             c. This Agreement may be amended at any time by the parties hereto,
         subject to approval by the Trust's Board of Trustees and, if required
         by applicable SEC rules and regulations, a vote of the majority of the
         outstanding voting securities of the Fund affected by such change.

             d. The terms "assignment," "interested persons" and "majority of
         the outstanding voting securities" shall have the meaning set forth for
         such terms in the 1940 Act.

         10. SEVERABILITY. If any provision of this Agreement shall become or
shall be found to be invalid by a court decision, statute, rule or otherwise,
the remainder of this Agreement shall not be affected thereby.

         11. NOTICE. Any notices under this Agreement shall be in writing
addressed and delivered personally (or by telecopy) or mailed postage-paid, to
the other party at such address as such other party may designate in accordance
with


                                     - 7 -

this paragraph for the receipt of such notice. Until further notice to the other
party, it is agreed that the address of the Trust and that of the Advisor for
this purpose shall be 311 Pike Street, Cincinnati, Ohio 45202 and that the
address of the Sub-Advisor shall be One Citicorp Center, 153 East 53rd Street,
New York, New York 10122.

         12. MISCELLANEOUS. Each party agrees to perform such further actions
and execute such further documents as are necessary to effectuate the purposes
hereof. This Agreement shall be construed and enforced in accordance with and
governed by the laws of the State of Ohio. The captions in this Agreement are
included for convenience only and in no way define or delimit any of the
provisions hereof or otherwise affect their construction or effect.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed and delivered in their names and on their behalf by the undersigned,
thereunto duly authorized, all as of the day and year first above written.

                             SUB-ADVISORY AGREEMENT

                         TOUCHSTONE GROWTH & INCOME FUND
                             TOUCHSTONE SERIES TRUST

     This SUB-ADVISORY AGREEMENT is made as of January 1, 1999, by and between
TOUCHSTONE ADVISORS, INC., an Ohio corporation (the "Advisor"), and SCUDDER
KEMPER INVESTMENTS, INC., a Delaware corporation (the "Sub-Advisor").

     WHEREAS, the Advisor is an investment advisor registered under the
Investment Advisers Act of 1940, as amended, and has been retained by Touchstone
Series Trust (formerly Select Advisors Trust A) (the "Trust"), a Massachusetts
business trust organized pursuant to a Declaration of Trust dated February 7,
1994 and registered as an open-end diversified management investment company
under the Investment Company Act of 1940 (the "1940 Act") to provide investment
advisory services to the Touchstone Growth & Income Fund (the "Fund"); and

     WHEREAS, the Sub-Advisor also is an investment advisor registered under the
Investment Advisers Act of 1940, as amended; and

     WHEREAS, the Advisor desires to retain the Sub-Advisor to furnish it with
portfolio management services in connection with the Advisor's investment
advisory activities on behalf of the Fund, and the Sub-Advisor is willing to
furnish such services to the Advisor and the Fund;

     NOW THEREFORE, in consideration of the terms and conditions hereinafter set
forth, it is agreed as follows:

     1.   EMPLOYMENT OF THE SUB-ADVISOR. In accordance with and subject to the
Investment Advisory Agreement between the Trust and the Advisor, attached hereto
as Exhibit A (the "Advisory Agreement"), the Advisor hereby appoints the
Sub-Advisor to manage the investment and reinvestment of those assets of the
Fund allocated to it by the Advisor (the "Fund Assets"), subject to the control
and direction of the Advisor and the Trust's Board of Trustees, for the period
and on the terms hereinafter set forth. The Advisor hereby represents that (i)
it has authority under the Advisory Agreement to appoint the Sub-Advisor to act
as an investment advisor to the Trust, and (ii) this Agreement is valid and
binding upon the Advisor. The Sub-Advisor hereby accepts such employment and
agrees during such period to render the services and to perform the duties
called for by this Agreement for the compensation herein provided. The
Sub-Advisor shall at all times maintain its registration as an investment
advisor under the Investment Advisers Act of 1940 and shall otherwise comply in
all material respects with all 


<PAGE>   2


applicable laws and regulations, both state and federal. The Sub-Advisor shall
for all purposes herein be deemed an independent contractor and shall, except as
expressly provided or authorized (whether herein or otherwise), have no
authority to act for or represent the Trust in any way or otherwise be deemed an
agent of the Trust or the Fund.

     2.   DUTIES OF THE SUB-ADVISOR. The Sub-Advisor will provide the following
services and undertake the following duties:

          a. The Sub-Advisor will manage the investment and reinvestment of the
     assets of the Fund, subject to and in accordance with the investment
     objectives, policies and restrictions of the Fund and any directions which
     the Advisor or the Trust's Board of Trustees may give from time to time
     with respect to the Fund. In furtherance of the foregoing, the Sub-Advisor
     will make all determinations with respect to the investment of the assets
     of the Fund and the purchase and sale of portfolio securities and shall
     take such steps as may be necessary or advisable to implement the same. The
     Sub-Advisor also will determine the manner in which voting rights, rights
     to consent to corporate action and any other rights pertaining to the
     portfolio securities will be exercised. The Sub-Advisor will render regular
     reports to the Trust's Board of Trustees, to the Advisor and to BARRA
     RogersCasey, Inc. (or such other advisor or advisors as the Advisor shall
     engage to assist it in the evaluation of the performance and activities of
     the Sub-Advisor). Such reports shall be made in such form and manner and
     with respect to such matters regarding the Fund and the Sub-Advisor as the
     Trust, the Advisor or BARRA RogersCasey, Inc. shall from time to time
     reasonably request.

          b. The Sub-Advisor shall provide support to the Advisor with respect
     to the marketing of the Fund in a manner comparable to the support provided
     to comparable clients of the Sub-Advisor, including but not limited to: (i)
     permission to use the Sub-Advisor's name as provided in Section 6, (ii)
     permission to use the past performance and investment history of the
     Sub-Advisor as the same is applicable to the Fund, provided counsel to the
     Trust determine that the use of such information and the manner of
     presentation of such information is legally permissible, (iii) access to
     the individual(s) responsible for day-to-day management of the Fund for
     marketing conferences, teleconferences and other activities involving the
     promotion of the Fund, subject to the reasonable request of the Advisor,
     (iv) permission to use biographical and historical data of the Sub-Advisor
     and individual manager(s), and (v) with respect to clients whose names are
     provided to the Advisor by the Sub-Advisor in writing prior to use,
     permission to use the names of these clients, subject to any restrictions
     imposed by clients on the use of such names or by the Investment Advisors
     Act of 1940 and the rules adopted thereunder.


                                      -2-

<PAGE>   3


          c. The Sub-Advisor will, in the name of the Fund, place orders for the
     execution of all portfolio transactions in accordance with the policies
     with respect thereto set forth in the Trust's registration statements under
     the 1940 Act and the Securities Act of 1933, as such registration
     statements may be in effect from time to time. In connection with the
     placement of orders for the execution of portfolio transactions, the
     Sub-Advisor will create and maintain all necessary brokerage records of the
     Fund in accordance with all applicable laws, rules and regulations,
     including but not limited to records required by Section 31(a) of the 1940
     Act. All records shall be the property of the Trust and shall be available
     for inspection and use by the Securities and Exchange Commission (the
     "SEC"), the Trust or any person retained by the Trust. Where applicable,
     such records shall be maintained by the Advisor for the periods and in the
     places required by Rule 31a-2 under the 1940 Act. When placing orders with
     brokers and dealers, the Sub-Advisor shall seek to obtain the most
     favorable price and execution available for the Fund, and in placing such
     orders the Sub-Advisor may consider a number of factors, including, without
     limitation, the overall direct net economic result to the Fund (including
     commissions, which may not be the lowest available but ordinarily should
     not be higher than the generally prevailing competitive range), the
     financial strength and stability of the broker, the efficiency with which
     the transaction will be effected, the ability to effect the transaction at
     all where a large block is involved and the availability of the broker or
     dealer to stand ready to execute possibly difficult transactions in the
     future. The Sub-Advisor is specifically authorized, to the extent
     authorized by law (including, without limitation, Section 28(e) of the
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay a
     broker or dealer who provides research services to the Sub-Advisor an
     amount of commission for effecting a portfolio transaction in excess of the
     amount of commission another broker or dealer would have charged for
     effecting such transaction, in recognition of such additional research
     services rendered by the broker or dealer, but only if the Sub-Advisor
     determines in good faith that the excess commission is reasonable in
     relation to the value of the brokerage and research services provided by
     such broker or dealer viewed in terms of the particular transaction or the
     Sub-Advisor's overall responsibilities with respect to discretionary
     accounts that it manages, and that the Fund derives or will derive a
     reasonably significant benefit from such research services. The Sub-Advisor
     will present a written report to the Board of Trustees of the Trust, at
     least quarterly and at such other times as reasonably requested by the
     Board of Trustees, indicating total brokerage expenses, actual or imputed,
     as well as the services obtained in consideration for such expenses, broken
     down by broker-dealer and containing such information as the Board of
     Trustees reasonably shall request.



                                      -3-

<PAGE>   4


          d. The Sub-Advisor may execute standard account documentation,
     agreements, contracts and other documents (collectively, the "Account
     Documents") as the Sub-Advisor may be requested by brokers, dealers,
     counterparties and other persons in connection with the Sub-Advisor's
     management of the Fund Assets, provided that the Advisor and the Trust's
     Board of Trustees first authorize the Sub-Advisor to execute Account
     Documents. In such respect, and only for this limited purpose, the
     Sub-Advisor shall act as the agent and/or attorney-in-fact of the Trust
     and/or the Advisor.

          e. The Advisor recognizes that, subject to the provisions of Section
     2c, Scudder Investor Services, Inc. or its successor ("SIS"), an affiliate
     of the Sub-Advisor, may act as the regular broker for the Fund so long as
     it is lawful for it so to act and that SIS may be a major recipient of
     brokerage commissions paid by the Fund. SIS may effect securities
     transactions for the Fund only if (i) the commissions, fees or other
     remuneration received or to be received by it are reasonable and fair
     compared to the commissions, fees or other remuneration received by other
     brokers in connection with comparable transactions involving similar
     securities being purchased or sold on a securities exchange during a
     comparable period of time and (ii) the Trustees, including a majority of
     those Trustees who are not interested persons, have adopted procedures
     pursuant to Rule 17e-1 under the 1940 Act for determining the permissible
     level of such commissions.

          f. The Advisor understands that (i) when orders to purchase or sell
     the same security on identical terms are placed by more than one of the
     funds and/or other advisory accounts managed by the Sub-Advisor or its
     affiliates, the transactions generally will be executed as received,
     although a fund or advisory account that does not direct trades to a
     specific broker ("free trades") usually will have its order executed first,
     (ii) although all orders placed on behalf of the Fund will be considered
     free trades, having an order placed first in the market does not
     necessarily guarantee the most favorable price, and (iii) purchases will be
     combined where possible for the purpose of negotiating brokerage
     commissions, which in some cases might have a detrimental effect on the
     price or volume of the security in a particular transaction as far as the
     Fund is concerned.

          g. The Sub-Advisor may enter into arrangements with other persons
     affiliated with the Sub-Advisor for the provision of certain personnel and
     facilities to the Sub-Advisor to better enable it to fulfill its duties and
     obligations under this Agreement.


                                      -4-

<PAGE>   5


          h. In the event of any reorganization or other change in the
     Sub-Advisor, its investment principals, supervisors or members of its
     investment (or comparable) committee, the Sub-Advisor shall give the
     Advisor and the Trust's Board of Trustees written notice of such
     reorganization or change within a reasonable time (but not later than 30
     days) after such reorganization or change.

          i. The Sub-Advisor will bear its expenses of providing services to the
     Fund pursuant to this Agreement except such expenses as are undertaken by
     the Advisor or the Trust.

          j. The Sub-Advisor will manage the Fund Assets and the investment and
     reinvestment of such assets so as to seek to comply with the provisions of
     the 1940 Act and with Subchapter M of the Internal Revenue Code of 1986, as
     amended.

     3.   COMPENSATION OF THE SUB-ADVISOR.

          a. As compensation for the services to be rendered and duties
     undertaken hereunder by the Sub-Advisor, the Advisor will pay to the
     Sub-Advisor a monthly fee equal on an annual basis to 0.50% of the first
     $150 million of the average daily net assets of the Combined Funds, and
     0.45% of such average daily net assets in excess of $150 million.

          b. "Combined Funds," for purposes of this Section 3, means the
     combined assets of the Fund and the Touchstone Growth & Income Fund of the
     Touchstone Variable Series Trust, to which the Sub-Advisor also acts as an
     investment advisor.

          c. The fee of the Sub-Advisor hereunder shall be computed and accrued
     daily and paid monthly. If the Sub-Advisor serves in such capacity for less
     than the whole of any period specified in this Section 3a, the fee to the
     Sub-Advisor shall be prorated. For purposes of calculating the
     Sub-Advisor's fee, the daily value of the Combined Funds shall be computed
     by the same method as the Trust and the Touchstone Variable Series Trust
     use, respectively, to compute the net asset value of each such Fund for
     purposes of purchases and redemptions of interests thereof.

          d. The Sub-Advisor reserves the right to waive all or a part of its
     fees hereunder.

     4.   ACTIVITIES OF THE SUB-ADVISOR. It is understood that the Sub-Advisor
may perform investment advisory services for various other clients, including
other investment companies. Furthermore, it is understood that the Sub-Advisor
may give 

                                      -5-

<PAGE>   6

advice, and take action, with respect to its other clients that may differ from
the advice given, or the time and nature of the action taken, with respect to
the Fund. The Sub-Advisor will report to the Board of Trustees of the Trust (at
regular quarterly meetings and at such other times as such Board of Trustees
reasonably shall request) (i) the financial condition and prospects of the
Sub-Advisor, (ii) the nature and amount of transactions affecting the Fund that
involve the Sub-Advisor and affiliates of the Sub-Advisor, (iii) information
regarding any potential conflicts of interest arising by reason of its
continuing provision of advisory services to the Fund and to its other accounts,
and (iv) such other information as the Board of Trustees shall reasonably
request regarding the Fund, the Fund's performance, the performance of other
comparable accounts to whom the Sub-Advisor provides services and the plans of,
and the capability of, the Sub-Advisor with respect to providing future services
to the Fund and its other accounts. The Sub-Advisor agrees, on an ongoing basis,
to notify the Advisor of any change in the individual(s) responsible for
day-to-day management of the Fund and any material change in the investment
strategies employed by the Sub-Advisor in managing the Fund. At least annually,
the Sub-Advisor shall report to the Trustees the total number and type of such
other accounts and the approximate total asset value thereof (but not the
identities of the beneficial owners of such accounts). The Sub-Advisor agrees to
submit to the Trust a statement defining its policies with respect to the
allocation of investment opportunities among the Fund and its other clients.

     It is understood that the Sub-Advisor may become interested in the Trust as
an interest holder or otherwise.

     The Sub-Advisor has supplied to the Advisor and the Trust copies of its
Form ADV with all exhibits and attachments thereto (including the Sub-Advisor's
statement of financial condition) and will hereafter supply to the Advisor,
promptly upon the preparation thereof, copies of all amendments or restatements
of such document.

     Nothing in this Agreement shall prevent the Sub-Advisor, any parent,
subsidiary or affiliate, or any director or officer thereof, from acting as
investment advisor for any other person, firm, or corporation, and shall not in
any way limit or restrict the Sub-Advisor or any of its directors, officers,
stockholders or employees from buying, selling or trading any securities or
commodities for its or their own account or for the account of others for whom
it or they may be acting, if such activities will not adversely affect or
otherwise impair the performance by the Sub-Advisor of its duties and
obligations under this Agreement. The Sub-Advisor will (i) supply to the
Advisor, upon the execution of this Agreement, with a true copy of its currently
effective Code of Ethics and policies regarding insider trading and (ii)
thereafter supply to Advisor copies of any amendments to or restatements of such
Code of Ethics or insider trading policies. The Sub-Advisor agrees to provide
the Advisor, on a quarterly basis, a report with respect to material violations
of the 


                                      -6-

<PAGE>   7


Sub-Advisor's Code of Ethics or insider trading policies by portfolio managers
who have responsibility for managing the Fund or a written statement indicating
that no such violations have occurred during the quarter. In addition, the
Sub-Advisor agrees to provide to the Advisor such other information concerning
violations of its Code of Ethics or insider trading policies to the same extent
that it provides such information to the Boards of Directors of its proprietary
mutual funds. The parties agree to be bound by the provisions of Rule 17j-1
under the 1940 Act as it may be amended to the extent that the provisions of the
Rule are stricter than the provisions of this paragraph.

     5.   PROVISION OF INFORMATION BY THE ADVISOR. To facilitate the
Sub-Advisor's fulfillment of its obligations under this Agreement, the Advisor
agrees (i) promptly to provide the Sub-Advisor with all amendments or
supplements to the Trust's registration statements, its Agreement and
Declaration of Trust, and its By-Laws, (ii) on an ongoing basis, to notify the
Sub-Advisor expressly in writing of each change in the fundamental and
nonfundamental investment policies of the Fund, (iii) to provide or cause to be
provided to the Sub-Advisor on an ongoing basis such assistance as may
reasonably be requested by the Sub-Advisor in connection with its activities
under this Agreement, including, without limitation, information concerning the
Fund, its available funds, or funds that may reasonably become available for
investment, and information as to the general condition of the Fund's affairs,
(iv) to provide or cause to be provided to the Sub-Advisor on an ongoing basis
such information as is reasonably requested by the Sub-Advisor for performance
by the Sub-Advisor of its obligations under this Agreement and the Sub-Advisor
shall not be in breach of any term of this Agreement or be deemed to have acted
negligently if such alleged breach or negligent act is the result of the
Advisor's failure to provide or cause to be provided such requested information
and the Sub-Advisor's reliance on the information most recently furnished to the
Sub-Advisor, and (v) promptly to provide the Sub-Advisor with any guidelines and
procedures applicable to the Sub-Advisor or the Fund adopted from time to time
by the Board of Trustees of the Trust and all amendments thereto.

     6.   USE OF NAMES. Neither the Advisor nor the Trust shall use the name of
the Sub-Advisor in any prospectus, sales literature or other material relating
to the Advisor or the Trust in any manner not approved in advance by the
Sub-Advisor; provided, however, that the Sub-Advisor will approve all uses of
its name which merely refer in accurate terms to its appointment hereunder or
which are required by the SEC or a state securities commission; and provided
further, that in no event shall such approval be unreasonably withheld. The
Sub-Advisor shall not use the name of the Advisor or the Trust in any material
relating to the Sub-Advisor in any manner not approved in advance by the Advisor
or the Trust, as the case may be; provided, however, that the Advisor and the
Trust shall each approve all uses of their respective names which merely refer
in accurate terms to the appointment of the Sub-Advisor hereunder or which are
required by the SEC or a 



                                      -7-

<PAGE>   8


state securities commission; and, provided further, that in no event shall such
approval be unreasonably withheld. Upon termination of this Agreement, the
Advisor and the Trust shall immediately cease to use the name of the
Sub-Advisor.

     7.   LIMITATION OF LIABILITY OF THE SUB-ADVISOR. Absent willful
misfeasance, bad faith, gross negligence, or reckless disregard of obligations
or duties hereunder on the part of the Sub-Advisor, the Sub-Advisor shall not be
subject to liability to the Advisor, the Trust or to any holder of an interest
in the Fund for any act or omission in the course of, or connected with,
rendering services hereunder or for any losses that may be sustained in the
purchase, holding or sale of any security. The Sub-Advisor shall not be liable
to the Advisor or the Trust for any loss suffered as a consequence of any action
or inaction of other service providers to the Trust, provided such action or
inaction of such other service providers to the Fund is not a result of the
willful misconduct, bad faith or gross negligence in the performance of, or
reckless disregard of, the duties of the Sub-Advisor under this Agreement. As
used in this Section 7, the term "Sub-Advisor" shall include the Sub-Advisor
and/or any of its affiliates and the directors, officers and employees of the
Sub-Advisor and/or any of its affiliates.

     8.   LIMITATION OF TRUST'S LIABILITY. The Sub-Advisor acknowledges that it
has received notice of and accepts the limitations upon the Trust's liability
set forth in its Declaration of Trust. The Sub-Advisor agrees that (i) the
Trust's obligations to the Sub-Advisor under this Agreement (or indirectly under
the Advisory Agreement) shall be limited, in any event to the assets of the Fund
and (ii) the Sub-Advisor shall not seek satisfaction of any such obligation from
the holders of shares of the Fund nor from any Trustee, officer, employee or
agent of the Trust.

     9.   FORCE MAJEURE. The Sub-Advisor shall not be liable for delays or
errors occurring by reason of circumstances beyond its control, including but
not limited to acts of civil or military authority, national emergencies, work
stoppages, fire, flood, catastrophe, acts of God, insurrection, war, riot, or
failure of communication or power supply. In the event of equipment breakdowns
beyond its control, the Sub-Advisor shall take reasonable steps to minimize
service interruptions but shall have no liability with respect thereto.

     10.  RENEWAL, TERMINATION AND AMENDMENT.

          a. This Agreement shall continue in effect, unless sooner terminated
     as hereinafter provided, until December 31, 1999; and it shall continue
     thereafter provided that such continuance is specifically approved by the
     parties and, in addition, at least annually by (i) the vote of the holders
     of a majority of the outstanding voting securities (as herein defined) of
     the Fund or by vote of a majority of the Trust's Board of Trustees and (ii)
     by the 


                                      -8-


<PAGE>   9


     vote of a majority of the Trustees who are not parties to this Agreement or
     interested persons of either the Advisor or the Sub-Advisor, cast in person
     at a meeting called for the purpose of voting on such approval.

          b. This Agreement may be terminated at any time, without payment of
     any penalty, (i) by the Advisor, by the Trust's Board of Trustees or by a
     vote of the majority of the outstanding voting securities of the Fund, in
     any such case upon not less than 60 days' prior written notice to the
     Sub-Advisor and (ii) by the Sub-Advisor upon not less than 60 days' prior
     written notice to the Advisor and the Trust. This Agreement shall terminate
     automatically in the event of its assignment.

          c. If this Agreement is not approved by the favorable vote of a
     majority of the outstanding voting securities of the Fund by February 4,
     1999, it will terminate as of the close of business on the last day of such
     period.

          d. This Agreement will also terminate upon written notice to the other
     party that the other party is in material breach of this Agreement, unless
     the other party in material breach of this Agreement cures such breach to
     the reasonable satisfaction of the party alleging the breach within 30 days
     after the written notice.

          e. This Agreement may be amended at any time by the parties hereto,
     subject to approval by the Trust's Board of Trustees and, if required by
     applicable SEC rules and regulations, a vote of the majority of the
     outstanding voting securities of the Fund affected by such change.

          f. The terms "affiliated persons," "assignment," "interested persons"
     and "majority of the outstanding voting securities" shall have the meaning
     set forth for such terms in Section 2(a) of the 1940 Act.

     11.  SEVERABILITY AND INCORPORATED EFFECT. If any provision of this
Agreement shall become or shall be found to be invalid by a court decision,
statute, rule or otherwise, the remainder of this Agreement shall not be
affected thereby. In addition, where the effect of a requirement of the 1940 Act
reflected in any provision of this Agreement is relaxed by a rule, regulation or
order of the SEC, whether of specific or general application, such provision
shall be deemed to incorporate the effect of such rule, regulation or order.

     12.  NOTICE. Any notices under this Agreement shall be in writing addressed
and delivered personally (or by telecopy) or mailed postage-paid, to the other
party at such address as such other party may designate in accordance with this
paragraph for the receipt of such notice. Until further notice to the other
party, 


                                      -9-

<PAGE>   10


it is agreed that the address of the Trust and that of the Advisor for this
purpose shall be 311 Pike Street, Cincinnati, Ohio 45202 and that the address of
the Sub-Advisor shall be 345 Park Avenue, New York, New York 10154.

     13.  MISCELLANEOUS. Each party agrees to perform such further actions and
execute such further documents as are necessary to effectuate the purposes
hereof. This Agreement shall be construed and enforced in accordance with and
governed by the laws of the State of Ohio, or any applicable provisions of the
1940 Act. To the extent that the laws of the State of Ohio, or any of the
provisions in the Agreement, conflict with applicable provisions of the 1940
Act, the latter shall control. The captions in this Agreement are included for
convenience only and in no way define or delimit any of the provisions hereof or
otherwise affect their construction or effect.

                             SUB-ADVISORY AGREEMENT

                           TOUCHSTONE VALUE PLUS FUND
                             TOUCHSTONE SERIES TRUST

         This SUB-ADVISORY AGREEMENT is made as of January 1, 1999, by and
between TOUCHSTONE ADVISORS, INC., an Ohio corporation (the "Advisor"), and FORT
WASHINGTON INVESTMENT ADVISORS, INC., an Ohio corporation (the "Sub-Advisor").

         WHEREAS, the Advisor is an investment advisor registered under the
Investment Advisers Act of 1940, as amended, and has been retained by Touchstone
Series Trust (formerly Select Advisors Trust A) (the "Trust"), a Massachusetts
business trust organized pursuant to a Declaration of Trust dated February 7,
1994 and registered as an open-end diversified management investment company
under the Investment Company Act of 1940 (the "1940 Act") to provide investment
advisory services to the Touchstone Value Plus Fund (the "Fund"); and

         WHEREAS, the Sub-Advisor also is an investment advisor registered under
the Investment Advisers Act of 1940, as amended; and

         WHEREAS, the Advisor desires to retain the Sub-Advisor to furnish it
with portfolio management services in connection with the Advisor's investment
advisory activities on behalf of the Fund, and the Sub-Advisor is willing to
furnish such services to the Advisor and the Fund;

         NOW THEREFORE, in consideration of the terms and conditions hereinafter
set forth, it is agreed as follows:

         1. EMPLOYMENT OF THE SUB-ADVISOR. In accordance with and subject to the
Investment Advisory Agreement between the Trust and the Advisor, attached hereto
as Exhibit A (the "Advisory Agreement"), the Advisor hereby appoints the
Sub-Advisor to manage the investment and reinvestment of those assets of the
Fund allocated to it by the Advisor (the "Fund Assets"), subject to the control
and direction of the Advisor and the Trust's Board of Trustees, for the period
and on the terms hereinafter set forth. The Sub-Advisor hereby accepts such
employment and agrees during such period to render the services and to perform
the duties called for by this Agreement for the compensation herein provided.
The Sub-Advisor shall at all times maintain its registration as an investment
advisor under the Investment Advisers Act of 1940 and shall otherwise comply in
all material respects with all applicable laws and regulations, both state and
federal. The Sub-Advisor shall for all purposes herein be deemed an independent
contractor and shall, except as expressly provided or authorized (whether herein
or otherwise),
<PAGE>   2
have no authority to act for or represent the Trust in any way or otherwise be
deemed an agent of the Trust or the Fund.

         2. DUTIES OF THE SUB-ADVISOR. The Sub-Advisor will provide the
following services and undertake the following duties:

            a. The Sub-Advisor will manage the investment and reinvestment of
         the assets of the Fund, subject to and in accordance with the
         investment objectives, policies and restrictions of the Fund and any
         directions which the Advisor or the Trust's Board of Trustees may give
         from time to time with respect to the Fund. In furtherance of the
         foregoing, the Sub-Advisor will make all determinations with respect to
         the investment of the assets of the Fund and the purchase and sale of
         portfolio securities and shall take such steps as may be necessary or
         advisable to implement the same. The Sub-Advisor also will determine
         the manner in which voting rights, rights to consent to corporate
         action and any other rights pertaining to the portfolio securities will
         be exercised. The Sub-Advisor will render regular reports to the
         Trust's Board of Trustees, to the Advisor and to BARRA RogersCasey,
         Inc. (or such other advisor or advisors as the Advisor shall engage to
         assist it in the evaluation of the performance and activities of the
         Sub-Advisor). Such reports shall be made in such form and manner and
         with respect to such matters regarding the Fund and the Sub-Advisor as
         the Trust, the Advisor or BARRA RogersCasey, Inc. shall from time to
         time request.

            b. The Sub-Advisor shall provide support to the Advisor with respect
         to the marketing of the Fund, including but not limited to: (i)
         permission to use the Sub-Advisor's name as provided in Section 5, (ii)
         permission to use the past performance and investment history of the
         Sub-Advisor as the same is applicable to the Fund, and (iii) access to
         the individual(s) responsible for day-to-day management of the Fund for
         marketing conferences, teleconferences and other activities involving
         the promotion of the Fund, subject to the reasonable request of the
         Advisor, (iv) permission to use biographical and historical data of the
         Sub-Advisor and individual manager(s), and (v) permission to use the
         names of clients to which the Sub-Advisor provides investment
         management services, subject to any restrictions imposed by clients on
         the use of such names.

            c. The Sub-Advisor will, in the name of the Fund, place orders for
         the execution of all portfolio transactions in accordance with the
         policies with respect thereto set forth in the Trust's registration
         statements under the 1940 Act and the Securities Act of 1933, as such
         registration statements may be in effect from time to time. In
         connection with the placement of orders for the execution of portfolio
         transactions, the Sub-Advisor will create and maintain all necessary
         brokerage records of the Fund in accordance with


                                     - 2 -
<PAGE>   3
         all applicable laws, rules and regulations, including but not limited
         to records required by Section 31(a) of the 1940 Act. All records shall
         be the property of the Trust and shall be available for inspection and
         use by the Securities and Exchange Commission (the "SEC"), the Trust or
         any person retained by the Trust. Where applicable, such records shall
         be maintained by the Advisor for the periods and in the places required
         by Rule 31a-2 under the 1940 Act. When placing orders with brokers and
         dealers, the Sub-Advisor's primary objective shall be to obtain the
         most favorable price and execution available for the Fund, and in
         placing such orders the Sub-Advisor may consider a number of factors,
         including, without limitation, the overall direct net economic result
         to the Fund (including commissions, which may not be the lowest
         available but ordinarily should not be higher than the generally
         prevailing competitive range), the financial strength and stability of
         the broker, the efficiency with which the transaction will be effected,
         the ability to effect the transaction at all where a large block is
         involved and the availability of the broker or dealer to stand ready to
         execute possibly difficult transactions in the future. The Sub-Advisor
         is specifically authorized, to the extent authorized by law (including,
         without limitation, Section 28(e) of the Securities Exchange Act of
         1934, as amended (the "Exchange Act"), to pay a broker or dealer who
         provides research services to the Sub-Advisor an amount of commission
         for effecting a portfolio transaction in excess of the amount of
         commission another broker or dealer would have charged for effecting
         such transaction, in recognition of such additional research services
         rendered by the broker or dealer, but only if the Sub-Advisor
         determines in good faith that the excess commission is reasonable in
         relation to the value of the brokerage and research services provided
         by such broker or dealer viewed in terms of the particular transaction
         or the Sub-Advisor's overall responsibilities with respect to
         discretionary accounts that it manages, and that the Fund derives or
         will derive a reasonably significant benefit from such research
         services. The Sub-Advisor will present a written report to the Board of
         Trustees of the Trust, at least quarterly, indicating total brokerage
         expenses, actual or imputed, as well as the services obtained in
         consideration for such expenses, broken down by broker-dealer and
         containing such information as the Board of Trustees reasonably shall
         request.

            d. In the event of any reorganization or other change in the
         Sub-Advisor, its investment principals, supervisors or members of its
         investment (or comparable) committee, the Sub-Advisor shall give the
         Advisor and the Trust's Board of Trustees written notice of such
         reorganization or change within a reasonable time (but not later than
         30 days) after such reorganization or change.


                                     - 3 -
<PAGE>   4
            e. The Sub-Advisor will bear its expenses of providing services to
         the Fund pursuant to this Agreement except such expenses as are
         undertaken by the Advisor or the Trust.

            f. The Sub-Advisor will manage the Fund Assets and the investment
         and reinvestment of such assets so as to comply with the provisions of
         the 1940 Act and with Subchapter M of the Internal Revenue Code of
         1986, as amended.

         3. COMPENSATION OF THE SUB-ADVISOR.

            a. As compensation for the services to be rendered and duties
         undertaken hereunder by the Sub-Advisor, the Advisor will pay to the
         Sub-Advisor a monthly fee equal on an annual basis to 0.45% of the
         average daily net assets of the Fund. Such fee shall be computed and
         accrued daily. If the Sub-Advisor serves in such capacity for less than
         the whole of any period specified in this Section 3a, the compensation
         to the Sub-Advisor shall be prorated. For purposes of calculating the
         Sub-Advisor's fee, the daily value of the Fund's net assets shall be
         computed by the same method as the Trust uses to compute the net asset
         value of the Fund for purposes of purchases and redemptions of
         interests thereof.

            b. The Sub-Advisor reserves the right to waive all or a part of its
         fees hereunder.

         4. ACTIVITIES OF THE SUB-ADVISOR. It is understood that the Sub-Advisor
may perform investment advisory services for various other clients, including
other investment companies. The Sub-Advisor will report to the Board of Trustees
of the Trust (at regular quarterly meetings and at such other times as such
Board of Trustees reasonably shall request) (i) the financial condition and
prospects of the Sub-Advisor, (ii) the nature and amount of transactions
affecting the Fund that involve the Sub-Advisor and affiliates of the
Sub-Advisor, (iii) information regarding any potential conflicts of interest
arising by reason of its continuing provision of advisory services to the Fund
and to its other accounts, and (iv) such other information as the Board of
Trustees shall reasonably request regarding the Fund, the Fund's performance,
the services provided by the Sub-Advisor to the Fund as compared to its other
accounts and the plans of, and the capability of, the Sub-Advisor with respect
to providing future services to the Fund and its other accounts. At least
annually, the Sub-Advisor shall report to the Trustees the total number and type
of such other accounts and the approximate total asset value thereof (but not
the identities of the beneficial owners of such accounts). The Sub-Advisor
agrees to submit to the Trust a statement defining its policies with respect to
the allocation of business among the Fund and its other clients.


                                     - 4 -
<PAGE>   5
         It is understood that the Sub-Advisor may become interested in the
Trust as an interest holder or otherwise.

         The Sub-Advisor has supplied to the Advisor and the Trust copies of its
Form ADV with all exhibits and attachments thereto (including the Sub-Advisor's
statement of financial condition) and will hereafter supply to the Advisor,
promptly upon the preparation thereof, copies of all amendments or restatements
of such document.

         5. USE OF NAMES. Neither the Advisor nor the Trust shall use the name
of the Sub-Advisor in any prospectus, sales literature or other material
relating to the Advisor or the Trust in any manner not approved in advance by
the Sub-Advisor; provided, however, that the Sub-Advisor will approve all uses
of its name which merely refer in accurate terms to its appointment hereunder or
which are required by the SEC or a state securities commission; and provided
further, that in no event shall such approval be unreasonably withheld. The
Sub-Advisor shall not use the name of the Advisor or the Trust in any material
relating to the Sub-Advisor in any manner not approved in advance by the Advisor
or the Trust, as the case may be; provided, however, that the Advisor and the
Trust shall each approve all uses of their respective names which merely refer
in accurate terms to the appointment of the Sub-Advisor hereunder or which are
required by the SEC or a state securities commission; and, provided further,
that in no event shall such approval be unreasonably withheld.

         6. LIMITATION OF LIABILITY OF THE SUB-ADVISOR. Absent willful
misfeasance, bad faith, gross negligence, or reckless disregard of obligations
or duties hereunder on the part of the Sub-Advisor, the Sub-Advisor shall not be
subject to liability to the Advisor, the Trust or to any holder of an interest
in the Fund for any act or omission in the course of, or connected with,
rendering services hereunder or for any losses that may be sustained in the
purchase, holding or sale of any security. As used in this Section 6, the term
"Sub-Advisor" shall include the Sub-Advisor and/or any of its affiliates and the
directors, officers and employees of the Sub-Advisor and/or any of its
affiliates.

         7. LIMITATION OF TRUST'S LIABILITY. The Sub-Advisor acknowledges that
it has received notice of and accepts the limitations upon the Trust's liability
set forth in its Declaration of Trust. The Sub-Advisor agrees that (i) the
Trust's obligations to the Sub-Advisor under this Agreement (or indirectly under
the Advisory Agreement) shall be limited, in any event to the assets of the Fund
and (ii) the Sub-Advisor shall not seek satisfaction of any such obligation from
the holders of shares of the Fund nor from any Trustee, officer, employee or
agent of the Trust.

         8. FORCE MAJEURE. The Sub-Advisor shall not be liable for delays or
errors occurring by reason of circumstances beyond its control, including but
not limited


                                     - 5 -
<PAGE>   6
to acts of civil or military authority, national emergencies, work stoppages,
fire, flood, catastrophe, acts of God, insurrection, war, riot, or failure of
communication or power supply. In the event of equipment breakdowns beyond its
control, the Sub-Advisor shall take reasonable steps to minimize service
interruptions but shall have no liability with respect thereto.

         9.  RENEWAL, TERMINATION AND AMENDMENT.

             a. This Agreement shall continue in effect, unless sooner
         terminated as hereinafter provided, until December 31, 1999; and it
         shall continue thereafter provided that such continuance is
         specifically approved by the parties and, in addition, at least
         annually by (i) the vote of the holders of a majority of the
         outstanding voting securities (as herein defined) of the Fund or by
         vote of a majority of the Trust's Board of Trustees and (ii) by the
         vote of a majority of the Trustees who are not parties to this
         Agreement or interested persons of either the Advisor or the

         subject to approval by the Trust's Board of Trustees and, if required
         by applicable SEC rules and regulations, a vote of the majority of the
         outstanding voting securities of the Fund affected by such change.

             d. The terms "assignment," "interested persons" and "majority of

                             SUB-ADVISORY AGREEMENT

                       TOUCHSTONE INCOME OPPORTUNITY FUND
                             TOUCHSTONE SERIES TRUST

         This SUB-ADVISORY AGREEMENT is made as of January 1, 1999, by and
between TOUCHSTONE ADVISORS, INC., an Ohio corporation (the "Advisor"), and
ALLIANCE CAPITAL MANAGEMENT, L.P., a limited partnership organized under the
laws of Delaware (the "Sub-Advisor").

         WHEREAS, the Advisor is an investment advisor registered under the
Investment Advisers Act of 1940, as amended, and has been retained by Touchstone
Series Trust (formerly Select Advisors Trust A) (the "Trust"), a Massachusetts
business trust organized pursuant to a Declaration of Trust dated February 7,
1994 and registered as an open-end diversified management investment company
under the Investment Company Act of 1940 (the "1940 Act") to provide investment
advisory services to the Touchstone Income Opportunity Fund (the "Fund"); and

         WHEREAS, the Sub-Advisor also is an investment advisor registered under
the Investment Advisers Act of 1940, as amended; and

         WHEREAS, the Advisor desires to retain the Sub-Advisor to furnish it
with portfolio management services in connection with the Advisor's investment
advisory activities on behalf of the Fund, and the Sub-Advisor is willing to
furnish such services to the Advisor and the Fund;

         NOW THEREFORE, in consideration of the terms and conditions hereinafter
set forth, it is agreed as follows:

         1. EMPLOYMENT OF THE SUB-ADVISOR. In accordance with and subject to the
Investment Advisory Agreement between the Trust and the Advisor, attached hereto
as Exhibit A (the "Advisory Agreement"), the Advisor hereby appoints the
Sub-Advisor to manage the investment and reinvestment of those assets of the
Fund allocated to it by the Advisor (the "Fund Assets"), subject to the
oversight responsibilities of the Advisor under the Advisory Agreement and of
the Trust's Board of Trustees under applicable law, for the period and on the
terms hereinafter set forth. The Sub-Advisor hereby accepts such employment and
agrees during such period to render the services and to perform the duties
called for by this Agreement for the compensation herein provided. The
Sub-Advisor shall at all times maintain its registration as an investment
advisor under the Investment Advisers Act of 1940 and shall otherwise comply in
all material respects with all applicable laws and regulations, both state and
federal. The Sub-Advisor shall for all purposes herein be deemed an independent
contractor and shall, except as
<PAGE>   2
expressly provided or authorized (whether herein or otherwise), have no
authority to act for or represent the Trust in any way or otherwise be deemed an
agent of the Trust or the Fund.

         2. DUTIES OF THE SUB-ADVISOR. The Sub-Advisor will provide the
following services and undertake the following duties:

            a. The Sub-Advisor will manage the investment and reinvestment of
         the assets of the Fund, subject to and in accordance with the
         investment objectives, policies and restrictions of the Fund and
         subject to the oversight responsibilities of the Advisor under the
         Advisory Agreement and of the Trust's Board of Trustees under
         applicable law, under each case with respect to the Fund. In
         furtherance of the foregoing, the Sub-Advisor will make all
         determinations with respect to the investment of the assets of the Fund
         and the purchase and sale of portfolio securities and shall take such
         steps as may be necessary or advisable to implement the same. The
         Sub-Advisor also will determine the manner in which voting rights,
         rights to consent to corporate action and any other rights pertaining
         to the portfolio securities will be exercised. The Sub-Advisor will
         render regular reports to the Trust's Board of Trustees, to the Advisor
         and to BARRA RogersCasey, Inc. (or such other advisor or advisors as
         the Advisor shall engage to assist it in the evaluation of the
         performance and activities of the Sub-Advisor). Such reports shall be
         made in such form and manner and with respect to such matters regarding
         the Fund and the Sub-Advisor as the Trust, the Advisor or BARRA
         RogersCasey, Inc. shall from time to time request.

            b. The Sub-Advisor shall provide support to the Advisor with respect
         to the marketing of the Fund, including but not limited to: (i)
         permission to use the Sub-Advisor's name as provided in Section 5, (ii)
         permission to use the past performance and investment history of the
         Sub-Advisor as the same is applicable to the Fund, and (iii) access to
         the individual(s) responsible for day-to-day management of the Fund for
         marketing conferences, teleconferences and other activities involving
         the promotion of the Fund, subject to the reasonable request of the
         Advisor, (iv) permission to use biographical and historical data of the
         Sub-Advisor and individual manager(s), and (v) permission to use the
         names of those clients to which the Sub-Advisor provides investment
         management services, subject to receipt of the consent of such clients
         to the use of their names.

            c. The Sub-Advisor will, in the name of the Fund, place orders for
         the execution of all portfolio transactions in accordance with the
         policies with respect thereto set forth in the Trust's registration
         statements under the 1940 Act and the Securities Act of 1933, as such
         registration statements may be in effect from time to time. In
         connection with the placement of


                                     - 2 -
<PAGE>   3
         orders for the execution of portfolio transactions, the Sub-Advisor
         will create and maintain all necessary brokerage records of the Fund in
         accordance with all applicable laws, rules and regulations, including
         but not limited to records required by Section 31(a) of the 1940 Act.
         All records shall be the property of the Trust and shall be available
         for inspection and use by the Securities and Exchange Commission (the
         "SEC"), the Trust or any person retained by the Trust. Where
         applicable, such records shall be maintained by the Advisor for the
         periods and in the places required by Rule 31a-2 under the 1940 Act.
         When placing orders with brokers and dealers, the Sub-Advisor's primary
         objective shall be to obtain the most favorable price and execution
         available for the Fund, and in placing such orders the Sub-Advisor may
         consider a number of factors, including, without limitation, the
         overall direct net economic result to the Fund (including commissions,
         which may not be the lowest available but ordinarily should not be
         higher than the generally prevailing competitive range), the financial
         strength and stability of the broker, the efficiency with which the
         transaction will be effected, the ability to effect the transaction at
         all where a large block is involved and the availability of the broker
         or dealer to stand ready to execute possibly difficult transactions in
         the future. The Sub-Advisor is specifically authorized, to the extent
         authorized by law (including, without limitation, Section 28(e) of the
         Securities Exchange Act of 1934, as amended (the "Exchange Act"), to
         pay a broker or dealer who provides research services to the
         Sub-Advisor an amount of commission for effecting a portfolio
         transaction in excess of the amount of commission another broker or
         dealer would have charged for effecting such transaction, in
         recognition of such additional research services rendered by the broker
         or dealer, but only if the Sub-Advisor determines in good faith that
         the excess commission is reasonable in relation to the value of the
         brokerage and research services provided by such broker or dealer
         viewed in terms of the particular transaction or the Sub-Advisor's
         overall responsibilities with respect to discretionary accounts that it
         manages. The Sub-Advisor will present a written report to the Board of
         Trustees of the Trust, at least quarterly, indicating total brokerage
         expenses, actual or imputed, as well as the services obtained in
         consideration for such expenses, broken down by broker-dealer and
         containing such information as the Board of Trustees reasonably shall
         request.

            d. In the event of any reorganization(s) or other change(s) in the
         Sub-Advisor, its executive officers or members of its investment (or
         comparable) committee that, individually or collectively, are likely to
         have a material adverse effect on the ability of the Sub-Advisor to
         manage the Fund or otherwise perform its obligations to the Advisor and
         the Trust under this Agreement, the Sub-Advisor shall give the Advisor
         and the Trust's Board of Trustees written notice of such reorganization
         or change within a reasonable time (but not later than 30 days) after
         such reorganization or change. In


                                     - 3 -
<PAGE>   4
         addition, the Sub-Advisor will notify the Advisor of any change in
         membership of the Sub-Advisor's general partners within a reasonable
         time (but not later than 30 days) after such change.

            e. The Sub-Advisor will bear its expenses of providing services to
         the Fund pursuant to this Agreement except such expenses as are
         undertaken by the Advisor or the Trust.

            f. The Sub-Advisor will manage the Fund Assets and the investment
         and reinvestment of such assets so as to comply with the provisions of
         the 1940 Act and with Subchapter M of the Internal Revenue Code of
         1986, as amended.

         3. COMPENSATION OF THE SUB-ADVISOR. As compensation for the services to
be rendered and duties undertaken hereunder by the Sub-Advisor, the Advisor will
pay to the Sub-Advisor a monthly fee equal on an annual basis to 0.40% of the
first $50 million of the average daily net assets of the Fund, 0.35% of the
average daily net assets of the Fund in excess of $50 million and up to $70
million and 0.30% of the average daily net assets of the Fund in excess of $70
million and up to $90 million and 0.25% of the average daily net assets of the
Fund in excess of $90 million. Such fee shall be computed and accrued daily. If
the Sub-Advisor serves in such capacity for less than the whole of any period
specified in this Section 3, the compensation to the Sub-Advisor shall be
prorated. For purposes of calculating the Sub-Advisor's fee, the daily value of
the Fund's net assets shall be computed by the same method as the Trust uses to
compute the net asset value of the Fund for purposes of purchases and
redemptions of interests thereof.

         4. ACTIVITIES OF THE SUB-ADVISOR. It is understood that the Sub-Advisor
may perform investment advisory services for various other clients, including
other investment companies. The Sub-Advisor will report to the Board of Trustees
of the Trust (at regular quarterly meetings and at such other times as such
Board of Trustees reasonably shall request) (i) the nature and amount of
transactions affecting the Fund that involve the Sub-Advisor and affiliates of
the Sub-Advisor, (ii) information regarding any potential conflicts of interest
arising by reason of its continuing provision of advisory services to the Fund
and to its other accounts, and (iii) such other information as the Board of
Trustees shall reasonably request regarding the Fund, the Fund's performance,
the services provided by the Sub-Advisor to the Fund as compared to its other
accounts and the plans of, and the capability of, the Sub-Advisor with respect
to providing future services to the Fund and its other accounts. The Sub-Advisor
agrees to submit to the Trust a statement defining its policies with respect to
the allocation of investment opportunities among the Fund and its other clients.


                                     - 4 -
<PAGE>   5
         It is understood that the Sub-Advisor may become interested in the
Trust as an interest holder or otherwise.

         The Sub-Advisor has supplied to the Advisor and the Trust copies of its
Form ADV with all exhibits and attachments thereto (including the Sub-Advisor's
statement of financial condition) and will hereafter supply to the Advisor,
promptly upon the preparation thereof, copies of all amendments or restatements
of such document.

         5. USE OF NAMES. Neither the Advisor nor the Trust shall use the name
of the Sub-Advisor in any prospectus, sales literature or other material
relating to the Advisor or the Trust in any manner not approved in advance by
the Sub-Advisor; provided, however, that the Sub-Advisor will approve all uses
of its name which merely refer in accurate terms to its appointment hereunder or
which are required by the SEC or a state securities commission; and provided
further, that in no event shall such approval be unreasonably withheld. The
Sub-Advisor shall not use the name of the Advisor or the Trust in any material
relating to the Sub-Advisor in any manner not approved in advance by the Advisor
or the Trust, as the case may be; provided, however, that the Advisor and the
Trust shall each approve all uses of their respective names which merely refer
in accurate terms to the appointment of the Sub-Advisor hereunder or which are
required by the SEC or a state securities commission; and, provided further,
that in no event shall such approval be unreasonably withheld.

         6. LIMITATION OF LIABILITY OF THE SUB-ADVISOR. Absent willful
misfeasance, bad faith, gross negligence, or reckless disregard of obligations
or duties hereunder on the part of the Sub-Advisor, the Sub-Advisor shall not be
subject to liability to the Advisor, the Trust or to any holder of an interest
in the Fund for any act or omission in the course of, or connected with,
rendering services hereunder or for any losses that may be sustained in the
purchase, holding or sale of any security. As used in this Section 6, the term
"Sub-Advisor" shall include the Sub-Advisor and/or any of its affiliates and the
directors, officers and employees of the Sub-Advisor and/or any of its
affiliates.

         7. LIMITATION OF TRUST'S LIABILITY. The Sub-Advisor acknowledges that
it has received notice of and accepts the limitations upon the Trust's liability
set forth in its Declaration of Trust. The Sub-Advisor agrees that (i) the
Trust's obligations to the Sub-Advisor under this Agreement (or indirectly under
the Advisory Agreement) shall be limited, in any event to the assets of the Fund
and (ii) the Sub-Advisor shall not seek satisfaction of any such obligation from
the holders of shares of the Fund nor from any Trustee, officer, employee or
agent of the Trust.

         8. FORCE MAJEURE. The Sub-Advisor shall not be liable for delays or
errors occurring by reason of circumstances beyond its control, including but
not limited


                                     - 5 -
<PAGE>   6
to acts of civil or military authority, national emergencies, work stoppages,
fire, flood, catastrophe, acts of God, insurrection, war, riot, or failure of
communication or power supply. In the event of equipment breakdowns beyond its
control, the Sub-Advisor shall take reasonable steps to minimize service
interruptions but shall have no liability with respect thereto.

         9.  RENEWAL, TERMINATION AND AMENDMENT.

             a. This Agreement shall continue in effect, unless sooner
         terminated as hereinafter provided, until December 31, 1999; and it
         shall continue thereafter provided that such continuance is
         specifically approved by the parties and, in addition, at least
         annually by (i) the vote of the holders of a majority of the
         outstanding voting securities (as herein defined) of the Fund or by
         vote of a majority of the Trust's Board of Trustees and (ii) by the
         vote of a majority of the Trustees who are not parties to this
         Agreement or interested persons of either the Advisor or the
         Sub-Advisor, cast in person at a meeting called for the purpose of
         voting on such approval.

             b. This Agreement may be terminated at any time, without payment of
         any penalty, (i) by the Advisor, by the Trust's Board of Trustees or by
         a vote of the majority of the outstanding voting securities of the
         Fund, in any such case upon not less than 60 days' prior written notice
         to the Sub-Advisor and (ii) by the Sub-Advisor upon not less than 60
         days' prior written notice to the Advisor and the Trust. This Agreement
         shall terminate automatically in the event of its assignment (as

         subject to approval by the Trust's Board of Trustees and, if required
         by applicable SEC rules and regulations, a vote of the majority of the
         outstanding voting securities of the Fund affected by such change.

             d. The terms "assignment" and "majority of the outstanding voting
         securities" shall have the meaning set forth for such terms in the 1940
         Act.

         10. SEVERABILITY. If any provision of this Agreement shall become or
shall be found to be invalid by a court decision, statute, rule or otherwise,
the remainder of this Agreement shall not be affected thereby.

                             TOUCHSTONE SERIES TRUST

         This SUB-ADVISORY AGREEMENT is made as of January 1, 1999, by and
between TOUCHSTONE ADVISORS, INC., an Ohio corporation (the "Advisor"), and
OPCAP ADVISORS(the "Sub-Advisor"), a subsidiary of Oppenheimer Capital, a

         WHEREAS, the Advisor is an investment advisor registered under the
Investment Advisers Act of 1940, as amended, and has been retained by Touchstone
Series Trust (formerly Select Advisors Trust A) (the "Trust"), a Massachusetts
business trust organized pursuant to a Declaration of Trust dated February 7,

         WHEREAS, the Sub-Advisor also is an investment advisor registered under
the Investment Advisers Act of 1940, as amended; and

         WHEREAS, the Advisor desires to retain the Sub-Advisor to furnish it
with portfolio management services in connection with the Advisor's investment
advisory activities on behalf of the Fund, and the Sub-Advisor is willing to
furnish such services to the Advisor and the Fund;

         NOW THEREFORE, in consideration of the terms and conditions hereinafter
set forth, it is agreed as follows:

         1. EMPLOYMENT OF THE SUB-ADVISOR. In accordance with and subject to the
Investment Advisory Agreement between the Trust and the Advisor, attached hereto
as Exhibit A (the "Advisory Agreement"), the Advisor hereby appoints the
Sub-Advisor to manage the investment and reinvestment of those assets of the
Fund allocated to it by the Advisor (the "Fund Assets"), subject to the control
and direction of the Advisor and the Trust's Board of Trustees, for the period
and on the terms hereinafter set forth. The Sub-Advisor hereby accepts such
employment and agrees during such period to render the services and to perform
the duties called for by this Agreement for the compensation herein provided.
The Sub-Advisor shall at all times maintain its registration as an investment
advisor under the Investment Advisers Act of 1940 and shall otherwise comply in
all material respects with all applicable laws and regulations, both state and
federal. The Sub-Advisor shall for all purposes herein be deemed an independent
contractor and shall, except as expressly provided or authorized (whether herein
or otherwise),
<PAGE>   2
have no authority to act for or represent the Trust in any way or otherwise be
deemed an agent of the Trust or the Fund.

         2. DUTIES OF THE SUB-ADVISOR. The Sub-Advisor will provide the
following services and undertake the following duties:

            a. The Sub-Advisor will manage the investment and reinvestment of
         the assets of the Fund, subject to and in accordance with the
         investment objectives, policies and restrictions of the Fund and any
         directions which the Advisor or the Trust's Board of Trustees may give
         from time to time with respect to the Fund. In furtherance of the
         foregoing, the Sub-Advisor will make all determinations with respect to
         the investment of the assets of the Fund and the purchase and sale of
         portfolio securities and shall take such steps as may be necessary or
         advisable to implement the same. The Sub-Advisor also will determine
         the manner in which voting rights, rights to consent to corporate
         action and any other rights pertaining to the portfolio securities will
         be exercised. The Sub-Advisor will render regular reports to the
         Trust's Board of Trustees, to the Advisor and to BARRA RogersCasey,
         Inc. (or such other advisor or advisors as the Advisor shall engage to
         assist it in the evaluation of the performance and activities of the
         Sub-Advisor). Such reports shall be made in such form and manner and
         with respect to such matters regarding the Fund and the Sub-Advisor as
         the Trust, the Advisor or BARRA RogersCasey, Inc. shall from time to
         time request.

            b. The Sub-Advisor shall provide support to the Advisor with respect
         to the marketing of the Fund, including but not limited to: (i)
         permission to use the Sub-Advisor's name as provided in Section 5, (ii)
         permission to use the past performance and investment history of the
         Sub-Advisor as the same is applicable to the Fund, and (iii) access to
         the individual(s) responsible for day-to-day management of the Fund for
         marketing conferences, teleconferences and other activities involving
         the promotion of the Fund, subject to the reasonable request of the
         Advisor, (iv) permission to use biographical and historical data of the
         Sub-Advisor and individual manager(s), and (v) permission to use the
         names of clients to which the Sub-Advisor provides investment
         management services, subject to any restrictions imposed by clients on
         the use of such names.

            c. The Sub-Advisor will, in the name of the Fund, place orders for
         the execution of all portfolio transactions in accordance with the
         policies with respect thereto set forth in the Trust's registration
         statements under the 1940 Act and the Securities Act of 1933, as such
         registration statements may be in effect from time to time. In
         connection with the placement of orders for the execution of portfolio
         transactions, the Sub-Advisor will create and maintain all necessary
         brokerage records of the Fund in accordance with


                                     - 2 -
<PAGE>   3
         all applicable laws, rules and regulations, including but not limited
         to records required by Section 31(a) of the 1940 Act. All records shall
         be the property of the Trust and shall be available for inspection and
         use by the Securities and Exchange Commission (the "SEC"), the Trust or
         any person retained by the Trust. Where applicable, such records shall
         be maintained by the Advisor for the periods and in the places required
         by Rule 31a-2 under the 1940 Act. When placing orders with brokers and
         dealers, the Sub-Advisor's primary objective shall be to obtain the
         most favorable price and execution available for the Fund, and in
         placing such orders the Sub-Advisor may consider a number of factors,
         including, without limitation, the overall direct net economic result
         to the Fund (including commissions, which may not be the lowest
         available but ordinarily should not be higher than the generally
         prevailing competitive range), the financial strength and stability of
         the broker, the efficiency with which the transaction will be effected,
         the ability to effect the transaction at all where a large block is
         involved and the availability of the broker or dealer to stand ready to
         execute possibly difficult transactions in the future. The Sub-Advisor
         is specifically authorized, to the extent authorized by law (including,
         without limitation, Section 28(e) of the Securities Exchange Act of
         1934, as amended (the "Exchange Act"), to pay a broker or dealer who
         provides research services to the Sub-Advisor an amount of commission
         for effecting a portfolio transaction in excess of the amount of
         commission another broker or dealer would have charged for effecting
         such transaction, in recognition of such additional research services
         rendered by the broker or dealer, but only if the Sub-Advisor
         determines in good faith that the excess commission is reasonable in
         relation to the value of the brokerage and research services provided
         by such broker or dealer viewed in terms of the particular transaction
         or the Sub-Advisor's overall responsibilities with respect to
         discretionary accounts that it manages, and that the Fund derives or
         will derive a reasonably significant benefit from such research
         services. The Sub-Advisor will present a written report to the Board of
         Trustees of the Trust, at least quarterly, indicating total brokerage
         expenses, actual or imputed, as well as the services obtained in
         consideration for such expenses, broken down by broker-dealer and
         containing such information as the Board of Trustees reasonably shall
         request.

            d. The Advisor recognizes that, subject to the foregoing provisions
         of this Section 2, an affiliate of the Sub-Advisor may act as the
         regular broker for the fund so long as it is lawful for it so to act
         and that such affiliate may be a major recipient of brokerage
         commissions paid by the fund. Any such affiliate may effect securities
         transactions for the fund only if (1) the commissions, fees or other
         remuneration received or to be received by it are reasonable and fair
         compared to the commissions, fees or other remuneration received by
         other brokers in connections with comparable


                                     - 3 -
<PAGE>   4
         transactions involving similar securities being purchased or sold on a
         securities exchange during a comparable period of time and (2) the
         Trustees, including a majority of those Trustees who are not interested
         persons, have adopted procedures pursuant toe Rule 17e-1 under the 1940
         Act for determining the permissible level of such commissions.

            e. The Advisor understands that (i) when orders to purchase or sell
         the same security on identical terms are placed by more than one of the
         funds and/or other advisory accounts managed by the Sub-Advisor or its
         affiliates, the transactions generally will be executed as received,
         although a fund or advisory account that does not direct trades to a
         specific broker ("free trades") usually will have its order executed
         first, (ii) although all orders placed on behalf of the Fund will be
         considered free trades, having an order placed first does not
         necessarily guarantee the most favorable price, and (iii) purchases
         will be combined where possible for the purpose of negotiating
         brokerage commissions, which in some cases might have a detrimental
         effect on the price or volume of the security in a particular
         transaction as far as the Fund is concerned.

            f. In the event of any reorganization or other change in the
         Sub-Advisor, its investment principals, supervisors or members of its
         investment (or comparable) committee, the Sub-Advisor shall give the
         Advisor and the Trust's Board of Trustees written notice of such
         reorganization or change within a reasonable time (but not later than
         30 days) after such reorganization or change.

            g. The Sub-Advisor will bear its expenses of providing services to
         the Fund pursuant to this Agreement except such expenses as are
         undertaken by the Advisor or the Trust.

            h. The Sub-Advisor will manage the Fund Assets and the investment
         and reinvestment of such assets so as to comply with the provisions of
         the 1940 Act and with Subchapter M of the Internal Revenue Code of
         1986, as amended.

         3. COMPENSATION OF THE SUB-ADVISOR.

            a. As compensation for the services to be rendered and duties
         undertaken hereunder by the Sub-Advisor, the Advisor will pay to the
         Sub-Advisor a monthly fee equal on an annual basis to 0.60% of the
         first $20 million of the average daily net assets of the Combined
         Funds, 0.50% of such average daily net assets in excess of $20 million
         and up to $50 million and 0.40% of such average daily net assets in
         excess of $50 million.


                                     - 4 -
<PAGE>   5
            b. "Combined Funds," for purposes of this Section 3, means the
         combined assets of the Fund and the Touchstone Balanced Fund of the
         Touchstone Variable Series Trust, to which fund the Sub-Advisor also
         acts as an investment advisor.

            c. The fee of the Sub-Advisor hereunder shall be computed and
         accrued daily. If the Sub-Advisor serves in such capacity for less than
         the whole of any period specified in Section 3a, the fee to the
         Sub-Advisor shall be prorated. For purposes of calculating the
         Sub-Advisor's fee, the daily value of the net assets of the Combined
         Funds shall be computed by the same method as the Trust and Touchstone
         Variable Series Trust use, respectively, to compute the net asset value
         of each such Fund for purposes of purchases and redemptions of
         interests thereof.

            d. The Sub-Advisor reserves the right to waive all or a part of its
         fees hereunder.

         4. ACTIVITIES OF THE SUB-ADVISOR. It is understood that the Sub-Advisor
may perform investment advisory services for various other clients, including
other investment companies. The Sub-Advisor will report to the Board of Trustees
of the Trust (at regular quarterly meetings and at such other times as such
Board of Trustees reasonably shall request) (i) the financial condition and
prospects of the Sub-Advisor, (ii) the nature and amount of transactions
affecting the Fund that involve the Sub-Advisor and affiliates of the
Sub-Advisor, (iii) information regarding any potential conflicts of interest
arising by reason of its continuing provision of advisory services to the Fund
and to its other accounts, and (iv) such other information as the Board of
Trustees shall reasonably request regarding the Fund, the Fund's performance,
the services provided by the Sub-Advisor to the Fund as compared to its other
accounts and the plans of, and the capability of, the Sub-Advisor with respect
to providing future services to the Fund and its other accounts. At least
annually, the Sub-Advisor shall report to the Trustees the total number and type
of such other accounts and the approximate total asset value thereof (but not
the identities of the beneficial owners of such accounts). The Sub-Advisor
agrees to submit to the Trust a statement defining its policies with respect to
the allocation of business among the Fund and its other clients.

         It is understood that the Sub-Advisor may become interested in the
Trust as an interest holder or otherwise.

         The Sub-Advisor has supplied to the Advisor and the Trust copies of its
Form ADV with all exhibits and attachments thereto (including the Sub-Advisor's
statement of financial condition) and will hereafter supply to the Advisor,
promptly upon the preparation thereof, copies of all amendments or restatements
of such document.


                                     - 5 -
<PAGE>   6
         Nothing in this Agreement shall prevent the Sub-Advisor, any parent,
subsidiary or affiliate, or any director or officer thereof, from acting as
investment advisor for any other person, firm, or corporation, and shall not in
any way limit or restrict the Sub-Advisor or any of its directors, officers,
stockholders or employees from buying, selling or trading any securities or
commodities for its or their own account or for the account of others for whom
it or they may be acting, if such activities will not adversely affect or
otherwise impair the performance by the Sub-Advisor of its duties and
obligations under this Agreement. The Sub-Advisor will (i) supply to the
Advisor, upon execution of this Agreement, with a true copy of its currently
effective Code of Ethics and policies regarding insider trading and (ii)
thereafter supply to Advisor copies of any amendments to or restatements of such
Code of Ethics or insider trading policies, and (iii) report to the Board of
Trustees not less often than quarterly with respect to any violations of such
Code of Ethics or insider trading policies by persons covered thereby to the
extent that such violations involve the assets or activities of the Fund.

         5. USE OF NAMES. Neither the Advisor nor the Trust shall use the name
of the Sub-Advisor in any prospectus, sales literature or other material
relating to the Advisor or the Trust in any manner not approved in advance by
the Sub-Advisor; provided, however, that the Sub-Advisor will approve all uses
of its name which merely refer in accurate terms to its appointment hereunder or
which are required by the SEC or a state securities commission; and provided
further, that in no event shall such approval be unreasonably withheld. The
Sub-Advisor shall not use the name of the Advisor or the Trust in any material
relating to the Sub-Advisor in any manner not approved in advance by the Advisor
or the Trust, as the case may be; provided, however, that the Advisor and the
Trust shall each approve all uses of their respective names which merely refer
in accurate terms to the appointment of the Sub-Advisor hereunder or which are
required by the SEC or a state securities commission; and, provided further,
that in no event shall such approval be unreasonably withheld.

         6. LIMITATION OF LIABILITY OF THE SUB-ADVISOR. Absent willful
misfeasance, bad faith, gross negligence, or reckless disregard of obligations
or duties hereunder on the part of the Sub-Advisor, the Sub-Advisor shall not be
subject to liability to the Advisor, the Trust or to any holder of an interest
in the Fund for any act or omission in the course of, or connected with,
rendering services hereunder or for any losses that may be sustained in the
purchase, holding or sale of any security. As used in this Section 6, the term
"Sub-Advisor" shall include the Sub-Advisor and/or any of its affiliates and the
directors, officers and employees of the Sub-Advisor and/or any of its
affiliates.

         7. LIMITATION OF TRUST'S LIABILITY. The Sub-Advisor acknowledges that
it has received notice of and accepts the limitations upon the Trust's liability
set forth


                                     - 6 -
<PAGE>   7
in its Declaration of Trust. The Sub-Advisor agrees that (i) the Trust's
obligations to the Sub-Advisor under this Agreement (or indirectly under the
Advisory Agreement) shall be limited, in any event to the assets of the Fund and
(ii) the Sub-Advisor shall not seek satisfaction of any such obligation from the
holders of shares of the Fund nor from any Trustee, officer, employee or agent
of the Trust.

         8. FORCE MAJEURE. The Sub-Advisor shall not be liable for delays or
errors occurring by reason of circumstances beyond its control, including but
not limited to acts of civil or military authority, national emergencies, work
stoppages, fire, flood, catastrophe, acts of God, insurrection, war, riot, or
failure of communication or power supply. In the event of equipment breakdowns
beyond its control, the Sub-Advisor shall take reasonable steps to minimize
service interruptions but shall have no liability with respect thereto.

         9. RENEWAL, TERMINATION AND AMENDMENT.

            a. This Agreement shall continue in effect, unless sooner terminated
         as hereinafter provided, until December 31, 1999; and it shall continue
         thereafter provided that such continuance is specifically approved by
         the parties and, in addition, at least annually by (i) the vote of the
         holders of a majority of the outstanding voting securities (as herein
         defined) of the Fund or by vote of a majority of the Trust's Board of
         Trustees and (ii) by the vote of a majority of the Trustees who are not
         parties to this Agreement or interested persons of either the Advisor
         or the Sub-Advisor, cast in person at a meeting called for the purpose
         of voting on such approval.

            b. This Agreement may be terminated at any time, without payment of
         any penalty, (i) by the Advisor, by the Trust's Board of Trustees or by
         a vote of the majority of the outstanding voting securities of the
         Fund, in any such case upon not less than 60 days' prior written notice
         to the Sub-Advisor and (ii) by the Sub-Advisor upon not less than 60
         days' prior written notice to the Advisor and the Trust. This Agreement
         shall terminate automatically in the event of its assignment.

            c. This Agreement may be amended at any time by the parties hereto,
         subject to approval by the Trust's Board of Trustees and, if required
         by applicable SEC rules and regulations, a vote of the majority of the
         outstanding voting securities of the Fund affected by such change.

            d. The terms "assignment," "interested persons" and "majority of the
         outstanding voting securities" shall have the meaning set forth for
         such terms in the 1940 Act.

         10. SEVERABILITY. If any provision of this Agreement shall become or
shall be found to be invalid by a court decision, statute, rule or otherwise,
the remainder of this Agreement shall not be affected thereby.

         11. NOTICE. Any notices under this Agreement shall be in writing
addressed and delivered personally (or by telecopy) or mailed postage-paid, to
the other party at such address as such other party may designate in accordance
with this paragraph for the receipt of such notice. Until further notice to the

                             SUB-ADVISORY AGREEMENT

                              TOUCHSTONE BOND FUND
                             TOUCHSTONE SERIES TRUST

         This SUB-ADVISORY AGREEMENT is made as of January 1, 1999, by and
between TOUCHSTONE ADVISORS, INC., an Ohio corporation (the "Advisor"), and FORT
WASHINGTON INVESTMENT ADVISORS, INC., an Ohio corporation (the "Sub-Advisor").

         WHEREAS, the Advisor is an investment advisor registered under the
Investment Advisers Act of 1940, as amended, and has been retained by Touchstone
Series Trust (formerly Select Advisors Trust A) (the "Trust"), a Massachusetts
business trust organized pursuant to a Declaration of Trust dated February 7,
1994 and registered as an open-end diversified management investment company
under the Investment Company Act of 1940 (the "1940 Act") to provide investment
advisory services to the Touchstone Bond Fund (the "Fund"); and

         WHEREAS, the Sub-Advisor also is an investment advisor registered under
the Investment Advisers Act of 1940, as amended; and

         WHEREAS, the Advisor desires to retain the Sub-Advisor to furnish it
with portfolio management services in connection with the Advisor's investment
advisory activities on behalf of the Fund, and the Sub-Advisor is willing to
furnish such services to the Advisor and the Fund;

         NOW THEREFORE, in consideration of the terms and conditions hereinafter
set forth, it is agreed as follows:

         1. EMPLOYMENT OF THE SUB-ADVISOR. In accordance with and subject to the
Investment Advisory Agreement between the Trust and the Advisor, attached hereto
as Exhibit A (the "Advisory Agreement"), the Advisor hereby appoints the
Sub-Advisor to manage the investment and reinvestment of those assets of the
Fund allocated to it by the Advisor (the "Fund Assets"), subject to the control
and direction of the Advisor and the Trust's Board of Trustees, for the period
and on the terms hereinafter set forth. The Sub-Advisor hereby accepts such
employment and agrees during such period to render the services and to perform
the duties called for by this Agreement for the compensation herein provided.
The Sub-Advisor shall at all times maintain its registration as an investment
advisor under the Investment Advisers Act of 1940 and shall otherwise comply in
all material respects with all applicable laws and regulations, both state and
federal. The Sub-Advisor shall for all purposes herein be deemed an independent
contractor and shall, except as expressly provided or authorized (whether herein
or otherwise), 
<PAGE>   2
have no authority to act for or represent the Trust in any way or otherwise be
deemed an agent of the Trust or the Fund.

         2. DUTIES OF THE SUB-ADVISOR. The Sub-Advisor will provide the
following services and undertake the following duties:

            a. The Sub-Advisor will manage the investment and reinvestment of
         the assets of the Fund, subject to and in accordance with the
         investment objectives, policies and restrictions of the Fund and any
         directions which the Advisor or the Trust's Board of Trustees may give
         from time to time with respect to the Fund. In furtherance of the
         foregoing, the Sub-Advisor will make all determinations with respect to
         the investment of the assets of the Fund and the purchase and sale of
         portfolio securities and shall take such steps as may be necessary or
         advisable to implement the same. The Sub-Advisor also will determine
         the manner in which voting rights, rights to consent to corporate
         action and any other rights pertaining to the portfolio securities will
         be exercised. The Sub-Advisor will render regular reports to the
         Trust's Board of Trustees, to the Advisor and to BARRA RogersCasey,
         Inc. (or such other advisor or advisors as the Advisor shall engage to
         assist it in the evaluation of the performance and activities of the
         Sub-Advisor). Such reports shall be made in such form and manner and
         with respect to such matters regarding the Fund and the Sub-Advisor as
         the Trust, the Advisor or BARRA RogersCasey, Inc. shall from time to
         time request.

            b. The Sub-Advisor shall provide support to the Advisor with respect
         to the marketing of the Fund, including but not limited to: (i)
         permission to use the Sub-Advisor's name as provided in Section 5, (ii)
         permission to use the past performance and investment history of the
         Sub-Advisor as the same is applicable to the Fund, and (iii) access to
         the individual(s) responsible for day-to-day management of the Fund for
         marketing conferences, teleconferences and other activities involving
         the promotion of the Fund, subject to the reasonable request of the
         Advisor, (iv) permission to use biographical and historical data of the
         Sub-Advisor and individual manager(s), and (v) permission to use the
         names of clients to which the Sub-Advisor provides investment
         management services, subject to any restrictions imposed by clients on
         the use of such names.

            c. The Sub-Advisor will, in the name of the Fund, place orders for
         the execution of all portfolio transactions in accordance with the
         policies with respect thereto set forth in the Trust's registration
         statements under the 1940 Act and the Securities Act of 1933, as such
         registration statements may be in effect from time to time. In
         connection with the placement of orders for the execution of portfolio
         transactions, the Sub-Advisor will create and maintain all necessary
         brokerage records of the Fund in accordance with 


                                     - 2 -
<PAGE>   3
         all applicable laws, rules and regulations, including but not limited
         to records required by Section 31(a) of the 1940 Act. All records shall
         be the property of the Trust and shall be available for inspection and
         use by the Securities and Exchange Commission (the "SEC"), the Trust or
         any person retained by the Trust. Where applicable, such records shall
         be maintained by the Advisor for the periods and in the places required
         by Rule 31a-2 under the 1940 Act. When placing orders with brokers and
         dealers, the Sub-Advisor's primary objective shall be to obtain the
         most favorable price and execution available for the Fund, and in
         placing such orders the Sub-Advisor may consider a number of factors,
         including, without limitation, the overall direct net economic result
         to the Fund (including commissions, which may not be the lowest
         available but ordinarily should not be higher than the generally
         prevailing competitive range), the financial strength and stability of
         the broker, the efficiency with which the transaction will be effected,
         the ability to effect the transaction at all where a large block is
         involved and the availability of the broker or dealer to stand ready to
         execute possibly difficult transactions in the future. The Sub-Advisor
         is specifically authorized, to the extent authorized by law (including,
         without limitation, Section 28(e) of the Securities Exchange Act of
         1934, as amended (the "Exchange Act"), to pay a broker or dealer who
         provides research services to the Sub-Advisor an amount of commission
         for effecting a portfolio transaction in excess of the amount of
         commission another broker or dealer would have charged for effecting
         such transaction, in recognition of such additional research services
         rendered by the broker or dealer, but only if the Sub-Advisor
         determines in good faith that the excess commission is reasonable in
         relation to the value of the brokerage and research services provided
         by such broker or dealer viewed in terms of the particular transaction
         or the Sub-Advisor's overall responsibilities with respect to
         discretionary accounts that it manages, and that the Fund derives or
         will derive a reasonably significant benefit from such research
         services. The Sub-Advisor will present a written report to the Board of
         Trustees of the Trust, at least quarterly, indicating total brokerage
         expenses, actual or imputed, as well as the services obtained in
         consideration for such expenses, broken down by broker-dealer and
         containing such information as the Board of Trustees reasonably shall
         request.

            d. In the event of any reorganization or other change in the
         Sub-Advisor, its investment principals, supervisors or members of its
         investment (or comparable) committee, the Sub-Advisor shall give the
         Advisor and the Trust's Board of Trustees written notice of such
         reorganization or change within a reasonable time (but not later than
         30 days) after such reorganization or change.


                                     - 3 -
<PAGE>   4
            e. The Sub-Advisor will bear its expenses of providing services to
         the Fund pursuant to this Agreement except such expenses as are
         undertaken by the Advisor or the Trust.

            f. The Sub-Advisor will manage the Fund Assets and the investment
         and reinvestment of such assets so as to comply with the provisions of
         the 1940 Act and with Subchapter M of the Internal Revenue Code of
         1986, as amended.

         3. COMPENSATION OF THE SUB-ADVISOR.

            a. As compensation for the services to be rendered and duties
         undertaken hereunder by the Sub-Advisor, the Advisor will pay to the
         Sub-Advisor a monthly fee equal on an annual basis to 0.30% of the
         average daily net assets of the Fund. Such fee shall be computed and
         accrued daily. If the Sub-Advisor serves in such capacity for less than
         the whole of any period specified in this Section 3a, the compensation
         to the Sub-Advisor shall be prorated. For purposes of calculating the
         Sub-Advisor's fee, the daily value of the Fund's net assets shall be
         computed by the same method as the Trust uses to compute the net asset
         value of the Fund for purposes of purchases and redemptions of
         interests thereof.

            b. The Sub-Advisor reserves the right to waive all or a part of its
         fees hereunder.

         4. ACTIVITIES OF THE SUB-ADVISOR. It is understood that the Sub-Advisor
may perform investment advisory services for various other clients, including
other investment companies. The Sub-Advisor will report to the Board of Trustees
of the Trust (at regular quarterly meetings and at such other times as such
Board of Trustees reasonably shall request) (i) the financial condition and
prospects of the Sub-Advisor, (ii) the nature and amount of transactions
affecting the Fund that involve the Sub-Advisor and affiliates of the
Sub-Advisor, (iii) information regarding any potential conflicts of interest
arising by reason of its continuing provision of advisory services to the Fund
and to its other accounts, and (iv) such other information as the Board of
Trustees shall reasonably request regarding the Fund, the Fund's performance,
the services provided by the Sub-Advisor to the Fund as compared to its other
accounts and the plans of, and the capability of, the Sub-Advisor with respect
to providing future services to the Fund and its other accounts. At least
annually, the Sub-Advisor shall report to the Trustees the total number and type
of such other accounts and the approximate total asset value thereof (but not
the identities of the beneficial owners of such accounts). The Sub-Advisor
agrees to submit to the Trust a statement defining its policies with respect to
the allocation of business among the Fund and its other clients.


                                     - 4 -
<PAGE>   5
         It is understood that the Sub-Advisor may become interested in the
Trust as an interest holder or otherwise.

         The Sub-Advisor has supplied to the Advisor and the Trust copies of its
Form ADV with all exhibits and attachments thereto (including the Sub-Advisor's
statement of financial condition) and will hereafter supply to the Advisor,
promptly upon the preparation thereof, copies of all amendments or restatements
of such document.

         5. USE OF NAMES. Neither the Advisor nor the Trust shall use the name
of the Sub-Advisor in any prospectus, sales literature or other material
relating to the Advisor or the Trust in any manner not approved in advance by
the Sub-Advisor; provided, however, that the Sub-Advisor will approve all uses
of its name which merely refer in accurate terms to its appointment hereunder or
which are required by the SEC or a state securities commission; and provided
further, that in no event shall such approval be unreasonably withheld. The
Sub-Advisor shall not use the name of the Advisor or the Trust in any material
relating to the Sub-Advisor in any manner not approved in advance by the Advisor
or the Trust, as the case may be; provided, however, that the Advisor and the
Trust shall each approve all uses of their respective names which merely refer
in accurate terms to the appointment of the Sub-Advisor hereunder or which are
required by the SEC or a state securities commission; and, provided further,
that in no event shall such approval be unreasonably withheld.

         6. LIMITATION OF LIABILITY OF THE SUB-ADVISOR.

            a. Absent willful misfeasance, bad faith, gross negligence, or
         reckless disregard of obligations or duties hereunder on the part of
         the Sub-Advisor, the Sub-Advisor shall not be subject to liability to
         the Advisor, the Trust or to any holder of an interest in the Fund for
         any act or omission in the course of, or connected with, rendering
         services hereunder or for any losses that may be sustained in the
         purchase, holding or sale of any security. As used in this Section 6,
         the term "Sub-Advisor" shall include the Sub-Advisor and/or any of its
         affiliates and the directors, officers and employees of the Sub-Advisor
         and/or any of its affiliates.

            b. The Advisor will indemnify the Sub-Advisor against, and hold it
         harmless from, any and all losses, claims, damages, liabilities or
         expenses (including reasonable counsel fees and expenses) resulting
         from acts or omissions of the Advisor and/or the Trust. Indemnification
         shall be made only after: (i) a final decision on the merits by a court
         or other body before whom the proceeding was brought that the Trust or
         the Advisor was liable for the damages claimed or (ii) in the absence
         of such a decision, a reasonable determination based upon a review of
         the facts, that the Trust or 


                                     - 5 -
<PAGE>   6
         the Advisor was liable for the damages claimed, which determination
         shall be made by either (a) the majority of a quorum of Trustees of the
         Trust who are neither "interested persons" of the Trust nor parties to
         the proceeding ("disinterested non-party Trustees") or (b) an
         independent legal counsel satisfactory to the parties hereto, whose
         determination shall be set forth in a written opinion. The Sub-Advisor
         shall be entitled to advances from the Trust for payment of the
         reasonable expenses incurred by it in connection with the matter as to
         which it is seeking indemnification in the manner and to the fullest
         extent that would be permissible under the indemnification provisions
         of the General Corporation Law of Ohio. The Sub-Advisor shall provide
         to the Trust a written affirmation of its good faith belief that the
         standard of conduct necessary for indemnification under such law has
         been met and a written undertaking to repay any such advance if it
         should ultimately be determined that the standard of conduct has not
         been met. In addition, at least one of the following additional
         conditions shall be met: (a) the Sub-Advisor shall provide security in
         form and amount acceptable to the Trust for its undertaking; (b) the
         Trust is insured against losses arising by reason of the advance; or
         (c) a majority of a quorum of the Trustees of the Trust, the members of
         which majority are disinterested non-party Trustees, or independent
         legal counsel in a written opinion, shall have determined, based on a
         review of facts readily available to the Trust at the time the advance
         is proposed to be made, that there is reason to believe that the
         Sub-Advisor will ultimately be found to be entitled to indemnification.

         7. LIMITATION OF TRUST'S LIABILITY. The Sub-Advisor acknowledges that
it has received notice of and accepts the limitations upon the Trust's liability
set forth in its Declaration of Trust. The Sub-Advisor agrees that (i) the
Trust's obligations to the Sub-Advisor under this Agreement (or indirectly under
the Advisory Agreement) shall be limited, in any event to the assets of the Fund
and (ii) the Sub-Advisor shall not seek satisfaction of any such obligation from
the holders of shares of the Fund nor from any Trustee, officer, employee or
agent of the Trust.

         8. FORCE MAJEURE. The Sub-Advisor shall not be liable for delays or
errors occurring by reason of circumstances beyond its control, including but
not limited to acts of civil or military authority, national emergencies, work
stoppages, fire, flood, catastrophe, acts of God, insurrection, war, riot, or
failure of communication or power supply. In the event of equipment breakdowns
beyond its control, the Sub-Advisor shall take reasonable steps to minimize
service interruptions but shall have no liability with respect thereto.

         9. RENEWAL, TERMINATION AND AMENDMENT.

            a. This Agreement shall continue in effect, unless sooner terminated
         as hereinafter provided, until December 31, 1999; and it shall 


                                     - 6 -
<PAGE>   7
         continue thereafter provided that such continuance is specifically
         approved by the parties and, in addition, at least annually by (i) the
         vote of the holders of a majority of the outstanding voting securities
         (as herein defined) of the Fund or by vote of a majority of the Trust's
         Board of Trustees and (ii) by the vote of a majority of the Trustees
         who are not parties to this Agreement or interested persons of either
         the Advisor or the Sub-Advisor, cast in person at a meeting called for
         the purpose of voting on such approval.

             b. This Agreement may be terminated at any time, without payment of
         any penalty, (i) by the Advisor, by the Trust's Board of Trustees or by
         a vote of the majority of the outstanding voting securities of the
         Fund, in any such case upon not less than 60 days' prior written notice
         to the Sub-Advisor and (ii) by the Sub-Advisor upon not less than 60
         days' prior written notice to the Advisor and the Trust. This Agreement
         shall terminate automatically in the event of its assignment.

             c. This Agreement may be amended at any time by the parties hereto,
         subject to approval by the Trust's Board of Trustees and, if required
         by applicable SEC rules and regulations, a vote of the majority of the
         outstanding voting securities of the Fund affected by such change.

             d. The terms "assignment," "interested persons" and "majority of
         the outstanding voting securities" shall have the meaning set forth for
         such terms in the 1940 Act.

         10. SEVERABILITY. If any provision of this Agreement shall become or
shall be found to be invalid by a court decision, statute, rule or otherwise,
the remainder of this Agreement shall not be affected thereby.

         11. NOTICE. Any notices under this Agreement shall be in writing
addressed and delivered personally (or by telecopy) or mailed postage-paid, to
the other party at such address as such other party may designate in accordance
with this paragraph for the receipt of such notice. Until further notice to the
other party, it is agreed that the address of the Trust and that of the Advisor
for this purpose shall be 311 Pike Street, Cincinnati, Ohio 45202 and that the
address of the Sub-Advisor shall be 420 East 4th Street, Cincinnati, Ohio 45202.

         12. MISCELLANEOUS. Each party agrees to perform such further actions
and execute such further documents as are necessary to effectuate the purposes
hereof. This Agreement shall be construed and enforced in accordance with and
governed by the laws of the State of Ohio. The captions in this Agreement are
included for convenience only and in no way define or delimit any of the
provisions hereof or otherwise affect their construction or effect.

                             SUB-ADVISORY AGREEMENT

                         TOUCHSTONE STANDBY INCOME FUND
                             TOUCHSTONE SERIES TRUST

         This SUB-ADVISORY AGREEMENT is made as of January 1, 1999, by and
between TOUCHSTONE ADVISORS, INC., an Ohio corporation (the "Advisor"), and FORT
WASHINGTON INVESTMENT ADVISORS, INC., an Ohio corporation (the "Sub-Advisor").

         WHEREAS, the Advisor is an investment advisor registered under the
Investment Advisers Act of 1940, as amended, and has been retained by Touchstone
Series Trust (formerly Select Advisors Trust A) (the "Trust"), a Massachusetts
business trust organized pursuant to a Declaration of Trust dated February 7,
1994 and registered as an open-end diversified management investment company
under the Investment Company Act of 1940 (the "1940 Act") to provide investment
advisory services to the Touchstone Standby Income Fund (the "Fund"); and

         WHEREAS, the Sub-Advisor also is an investment advisor registered under
the Investment Advisers Act of 1940, as amended; and

         WHEREAS, the Advisor desires to retain the Sub-Advisor to furnish it
with portfolio management services in connection with the Advisor's investment
advisory activities on behalf of the Fund, and the Sub-Advisor is willing to
furnish such services to the Advisor and the Fund;

         NOW THEREFORE, in consideration of the terms and conditions hereinafter
set forth, it is agreed as follows:

         1. EMPLOYMENT OF THE SUB-ADVISOR. In accordance with and subject to the
Investment Advisory Agreement between the Trust and the Advisor, attached hereto
as Exhibit A (the "Advisory Agreement"), the Advisor hereby appoints the
Sub-Advisor to manage the investment and reinvestment of those assets of the
Fund allocated to it by the Advisor (the "Fund Assets"), subject to the control
and direction of the Advisor and the Trust's Board of Trustees, for the period
and on the terms hereinafter set forth. The Sub-Advisor hereby accepts such
employment and agrees during such period to render the services and to perform
the duties called for by this Agreement for the compensation herein provided.
The Sub-Advisor shall at all times maintain its registration as an investment
advisor under the Investment Advisers Act of 1940 and shall otherwise comply in
all material respects with all applicable laws and regulations, both state and
federal. The Sub-Advisor shall for all purposes herein be deemed an independent
contractor and shall, except as expressly provided or authorized (whether herein
or otherwise),
<PAGE>   2
have no authority to act for or represent the Trust in any way or otherwise be
deemed an agent of the Trust or the Fund.

         2. DUTIES OF THE SUB-ADVISOR. The Sub-Advisor will provide the
following services and undertake the following duties:

            a. The Sub-Advisor will manage the investment and reinvestment of
         the assets of the Fund, subject to and in accordance with the
         investment objectives, policies and restrictions of the Fund and any
         directions which the Advisor or the Trust's Board of Trustees may give
         from time to time with respect to the Fund. In furtherance of the
         foregoing, the Sub-Advisor will make all determinations with respect to
         the investment of the assets of the Fund and the purchase and sale of
         portfolio securities and shall take such steps as may be necessary or
         advisable to implement the same. The Sub-Advisor also will determine
         the manner in which voting rights, rights to consent to corporate
         action and any other rights pertaining to the portfolio securities will
         be exercised. The Sub-Advisor will render regular reports to the
         Trust's Board of Trustees, to the Advisor and to BARRA RogersCasey,
         Inc. (or such other advisor or advisors as the Advisor shall engage to
         assist it in the evaluation of the performance and activities of the
         Sub-Advisor). Such reports shall be made in such form and manner and
         with respect to such matters regarding the Fund and the Sub-Advisor as
         the Trust, the Advisor or BARRA RogersCasey, Inc. shall from time to
         time request.

            b. The Sub-Advisor shall provide support to the Advisor with respect
         to the marketing of the Fund, including but not limited to: (i)
         permission to use the Sub-Advisor's name as provided in Section 5, (ii)
         permission to use the past performance and investment history of the
         Sub-Advisor as the same is applicable to the Fund, and (iii) access to
         the individual(s) responsible for day-to-day management of the Fund for
         marketing conferences, teleconferences and other activities involving
         the promotion of the Fund, subject to the reasonable request of the
         Advisor, (iv) permission to use biographical and historical data of the
         Sub-Advisor and individual manager(s), and (v) permission to use the
         names of clients to which the Sub-Advisor provides investment
         management services, subject to any restrictions imposed by clients on
         the use of such names.

            c. The Sub-Advisor will, in the name of the Fund, place orders for
         the execution of all portfolio transactions in accordance with the
         policies with respect thereto set forth in the Trust's registration
         statements under the 1940 Act and the Securities Act of 1933, as such
         registration statements may be in effect from time to time. In
         connection with the placement of orders for the execution of portfolio
         transactions, the Sub-Advisor will create and maintain all necessary
         brokerage records of the Fund in accordance with


                                     - 2 -
<PAGE>   3
         all applicable laws, rules and regulations, including but not limited
         to records required by Section 31(a) of the 1940 Act. All records shall
         be the property of the Trust and shall be available for inspection and
         use by the Securities and Exchange Commission (the "SEC"), the Trust or
         any person retained by the Trust. Where applicable, such records shall
         be maintained by the Advisor for the periods and in the places required
         by Rule 31a-2 under the 1940 Act. When placing orders with brokers and
         dealers, the Sub-Advisor's primary objective shall be to obtain the
         most favorable price and execution available for the Fund, and in
         placing such orders the Sub-Advisor may consider a number of factors,
         including, without limitation, the overall direct net economic result
         to the Fund (including commissions, which may not be the lowest
         available but ordinarily should not be higher than the generally
         prevailing competitive range), the financial strength and stability of
         the broker, the efficiency with which the transaction will be effected,
         the ability to effect the transaction at all where a large block is
         involved and the availability of the broker or dealer to stand ready to
         execute possibly difficult transactions in the future. The Sub-Advisor
         is specifically authorized, to the extent authorized by law (including,
         without limitation, Section 28(e) of the Securities Exchange Act of
         1934, as amended (the "Exchange Act"), to pay a broker or dealer who
         provides research services to the Sub-Advisor an amount of commission
         for effecting a portfolio transaction in excess of the amount of
         commission another broker or dealer would have charged for effecting
         such transaction, in recognition of such additional research services
         rendered by the broker or dealer, but only if the Sub-Advisor
         determines in good faith that the excess commission is reasonable in
         relation to the value of the brokerage and research services provided
         by such broker or dealer viewed in terms of the particular transaction
         or the Sub-Advisor's overall responsibilities with respect to
         discretionary accounts that it manages, and that the Fund derives or
         will derive a reasonably significant benefit from such research
         services. The Sub-Advisor will present a written report to the Board of
         Trustees of the Trust, at least quarterly, indicating total brokerage
         expenses, actual or imputed, as well as the services obtained in
         consideration for such expenses, broken down by broker-dealer and
         containing such information as the Board of Trustees reasonably shall
         request.

            d. In the event of any reorganization or other change in the
         Sub-Advisor, its investment principals, supervisors or members of its
         investment (or comparable) committee, the Sub-Advisor shall give the
         Advisor and the Trust's Board of Trustees written notice of such
         reorganization or change within a reasonable time (but not later than
         30 days) after such reorganization or change.


                                     - 3 -

            e. The Sub-Advisor will bear its expenses of providing services to
         the Fund pursuant to this Agreement except such expenses as are
         undertaken by the Advisor or the Trust.

            f. The Sub-Advisor will manage the Fund Assets and the investment
         and reinvestment of such assets so as to comply with the provisions of
         the 1940 Act and with Subchapter M of the Internal Revenue Code of
         1986, as amended.

         3. COMPENSATION OF THE SUB-ADVISOR.

            a. As compensation for the services to be rendered and duties
         undertaken hereunder by the Sub-Advisor, the Advisor will pay to the
         Sub-Advisor a monthly fee equal on an annual basis to 0.15% of the
         average daily net assets of the Fund. Such fee shall be computed and
         accrued daily. If the Sub-Advisor serves in such capacity for less than
         the whole of any period specified in this Section 3a, the compensation
         to the Sub-Advisor shall be prorated. For purposes of calculating the
         Sub-Advisor's fee, the daily value of the Fund's net assets shall be
         computed by the same method as the Trust uses to compute the net asset
         value of the Fund for purposes of purchases and redemptions of
         interests thereof.

            b. The Sub-Advisor reserves the right to waive all or a part of its
         fees hereunder.

         4. ACTIVITIES OF THE SUB-ADVISOR. It is understood that the Sub-Advisor
may perform investment advisory services for various other clients, including
other investment companies. The Sub-Advisor will report to the Board of Trustees
of the Trust (at regular quarterly meetings and at such other times as such
Board of Trustees reasonably shall request) (i) the financial condition and
prospects of the Sub-Advisor, (ii) the nature and amount of transactions
affecting the Fund that involve the Sub-Advisor and affiliates of the
Sub-Advisor, (iii) information regarding any potential conflicts of interest
arising by reason of its continuing provision of advisory services to the Fund
and to its other accounts, and (iv) such other information as the Board of
Trustees shall reasonably request regarding the Fund, the Fund's performance,
the services provided by the Sub-Advisor to the Fund as compared to its other
accounts and the plans of, and the capability of, the Sub-Advisor with respect
to providing future services to the Fund and its other accounts. At least
annually, the Sub-Advisor shall report to the Trustees the total number and type
of such other accounts and the approximate total asset value thereof (but not
the identities of the beneficial owners of such accounts). The Sub-Advisor
agrees to submit to the Trust a statement defining its policies with respect to
the allocation of business among the Fund and its other clients.


                                     - 4 -
<PAGE>   5
         It is understood that the Sub-Advisor may become interested in the
Trust as an interest holder or otherwise.

         The Sub-Advisor has supplied to the Advisor and the Trust copies of its
Form ADV with all exhibits and attachments thereto (including the Sub-Advisor's
statement of financial condition) and will hereafter supply to the Advisor,
promptly upon the preparation thereof, copies of all amendments or restatements
of such document.

         5. USE OF NAMES. Neither the Advisor nor the Trust shall use the name
of the Sub-Advisor in any prospectus, sales literature or other material
relating to the Advisor or the Trust in any manner not approved in advance by
the Sub-Advisor; provided, however, that the Sub-Advisor will approve all uses
of its name which merely refer in accurate terms to its appointment hereunder or
which are required by the SEC or a state securities commission; and provided
further, that in no event shall such approval be unreasonably withheld. The
Sub-Advisor shall not use the name of the Advisor or the Trust in any material
relating to the Sub-Advisor in any manner not approved in advance by the Advisor
or the Trust, as the case may be; provided, however, that the Advisor and the
Trust shall each approve all uses of their respective names which merely refer
in accurate terms to the appointment of the Sub-Advisor hereunder or which are
required by the SEC or a state securities commission; and, provided further,
that in no event shall such approval be unreasonably withheld.

         6. LIMITATION OF LIABILITY OF THE SUB-ADVISOR.

            a. Absent willful misfeasance, bad faith, gross negligence, or
         reckless disregard of obligations or duties hereunder on the part of
         the Sub-Advisor, the Sub-Advisor shall not be subject to liability to
         the Advisor, the Trust or to any holder of an interest in the Fund for
         any act or omission in the course of, or connected with, rendering
         services hereunder or for any losses that may be sustained in the
         purchase, holding or sale of any security. As used in this Section 6,
         the term "Sub-Advisor" shall include the Sub-Advisor and/or any of its
         affiliates and the directors, officers and employees of the Sub-Advisor
         and/or any of its affiliates.

            b. The Advisor will indemnify the Sub-Advisor against, and hold it
         harmless from, any and all losses, claims, damages, liabilities or
         expenses (including reasonable counsel fees and expenses) resulting
         from acts or omissions of the Advisor and/or the Trust. Indemnification
         shall be made only after: (i) a final decision on the merits by a court
         or other body before whom the proceeding was brought that the Trust or
         the Advisor was liable for the damages claimed or (ii) in the absence
         of such a decision, a reasonable determination based upon a review of
         the facts, that the Trust or


                                     - 5 -
<PAGE>   6
         the Advisor was liable for the damages claimed, which determination
         shall be made by either (a) the majority of a quorum of Trustees of the
         Trust who are neither "interested persons" of the Trust nor parties to
         the proceeding ("disinterested non-party Trustees") or (b) an
         independent legal counsel satisfactory to the parties hereto, whose
         determination shall be set forth in a written opinion. The Sub-Advisor
         shall be entitled to advances from the Trust for payment of the
         reasonable expenses incurred by it in connection with the matter as to
         which it is seeking indemnification in the manner and to the fullest
         extent that would be permissible under the indemnification provisions
         of the General Corporation Law of Ohio. The Sub-Advisor shall provide
         to the Trust a written affirmation of its good faith belief that the
         standard of conduct necessary for indemnification under such law has
         been met and a written undertaking to repay any such advance if it
         should ultimately be determined that the standard of conduct has not
         been met. In addition, at least one of the following additional
         conditions shall be met: (a) the Sub-Advisor shall provide security in
         form and amount acceptable to the Trust for its undertaking; (b) the
         Trust is insured against losses arising by reason of the advance; or
         (c) a majority of a quorum of the Trustees of the Trust, the members of
         which majority are disinterested non-party Trustees, or independent
         legal counsel in a written opinion, shall have determined, based on a
         review of facts readily available to the Trust at the time the advance
         is proposed to be made, that there is reason to believe that the
         Sub-Advisor will ultimately be found to be entitled to indemnification.

         7. LIMITATION OF TRUST'S LIABILITY. The Sub-Advisor acknowledges that
it has received notice of and accepts the limitations upon the Trust's liability
set forth in its Declaration of Trust. The Sub-Advisor agrees that (i) the
Trust's obligations to the Sub-Advisor under this Agreement (or indirectly under
the Advisory Agreement) shall be limited, in any event to the assets of the Fund
and (ii) the Sub-Advisor shall not seek satisfaction of any such obligation from
the holders of shares of the Fund nor from any Trustee, officer, employee or
agent of the Trust.

         8. FORCE MAJEURE. The Sub-Advisor shall not be liable for delays or
errors occurring by reason of circumstances beyond its control, including but
not limited to acts of civil or military authority, national emergencies, work
stoppages, fire, flood, catastrophe, acts of God, insurrection, war, riot, or
failure of communication or power supply. In the event of equipment breakdowns
beyond its control, the Sub-Advisor shall take reasonable steps to minimize
service interruptions but shall have no liability with respect thereto.

         9. RENEWAL, TERMINATION AND AMENDMENT.

            a. This Agreement shall continue in effect, unless sooner terminated
         as hereinafter provided, until December 31, 1999; and it shall


                                     - 6 -
<PAGE>   7
         continue thereafter provided that such continuance is specifically
         approved by the parties and, in addition, at least annually by (i) the
         vote of the holders of a majority of the outstanding voting securities
         (as herein defined) of the Fund or by vote of a majority of the Trust's
         Board of Trustees and (ii) by the vote of a majority of the Trustees
         who are not parties to this Agreement or interested persons of either
         the Advisor or the Sub-Advisor, cast in person at a meeting called for
         the purpose of voting on such approval.

            b. This Agreement may be terminated at any time, without payment of
         any penalty, (i) by the Advisor, by the Trust's Board of Trustees or by
         a vote of the majority of the outstanding voting securities of the
         Fund, in any such case upon not less than 60 days' prior written notice
         to the Sub-Advisor and (ii) by the Sub-Advisor upon not less than 60
         days' prior written notice to the Advisor and the Trust. This Agreement
         shall terminate automatically in the event of its assignment.

            c. This Agreement may be amended at any time by the parties hereto,
         subject to approval by the Trust's Board of Trustees and, if required
         by applicable SEC rules and regulations, a vote of the majority of the
         outstanding voting securities of the Fund affected by such change.

            d. The terms "assignment," "interested persons" and "majority of the
         outstanding voting securities" shall have the meaning set forth for
         such terms in the 1940 Act.

         10. SEVERABILITY. If any provision of this Agreement shall become or
shall be found to be invalid by a court decision, statute, rule or otherwise,
the remainder of this Agreement shall not be affected thereby.

         11. NOTICE. Any notices under this Agreement shall be in writing
addressed and delivered personally (or by telecopy) or mailed postage-paid, to
the other party at such address as such other party may designate in accordance
with this paragraph for the receipt of such notice. Until further notice to the
other party, it is agreed that the address of the Trust and that of the Advisor
for this purpose shall be 311 Pike Street, Cincinnati, Ohio 45202 and that the
address of the Sub-Advisor shall be 420 East 4th Street, Cincinnati, Ohio 45202.

         12. MISCELLANEOUS. Each party agrees to perform such further actions
and execute such further documents as are necessary to effectuate the purposes
hereof. This Agreement shall be construed and enforced in accordance with and
governed by the laws of the State of Ohio. The captions in this Agreement are
included for convenience only and in no way define or delimit any of the
provisions hereof or otherwise affect their construction or effect.

Select Advisors Trust A

Cincinnati, Ohio 45202

      Re:   Select Advisors Trust A

Ladies and Gentlemen:
   
      We are acting as special Massachusetts counsel to Select Advisors Trust A,
a Massachusetts business trust (the "Trust"), in connection with Post-Effective
Amendment No. 9 to the Trust's Registration Statement on Form N-1A to be filed
with the Securities and Exchange Commission on or about December 30, 1998 (the
"Amendment"), with respect to the shares of beneficial interest, par value
$.00001 per share (the "Shares") of its series Touchstone Value Plus Fund A (the
"Fund"), which were initially issued pursuant to the Trust's Post-Effective
Amendment No. 6 to its Registration Statement on Form N-1A, effective on May 1,
1998 (the "Prior Amendment"). You have requested that we deliver this opinion to
you to be used as an exhibit to the Amendment.
    

      In connection with the furnishing of this opinion, we have examined the
following documents:

            (a)   a certificate of the Secretary of State of the Commonwealth of
      Massachusetts as to the existence of the Trust;

            (b) a copy of the Trust's Declaration of Trust dated as of February
      7, 1994, Amendment No. 1 to the Declaration dated as of April 11, 1994,
      Amendment No. 2 to the Declaration dated as of August 1, 1994, Amendment
      No. 3 to the Declaration dated as of September 14, 1994, and Amendment No.
      4 to the Declaration dated as of September 18, 1997 (collectively, the
      "Declaration");

            (c) a copy of the Trust's Third Amended and Restated Establishment
      and Designation of Series dated as of September 18, 1997 (the "Designation
      of Series");

            (d) a certificate executed by the Assistant Secretary of the Trust
      (the "Secretary's Certificate"), certifying as to, and attaching copies
      of, the Trust's Declaration, Designation of Series, By-Laws, and certain
      resolutions adopted by the Trustees of the Trust at a meeting held on
      August 15, 1997 (the "Board Resolutions");

            (e) a copy of the Prior Amendment; and
   
            (e) a printer's proof dated December 29, 1998 of the Amendment.

      In such examination, we have assumed the genuineness of all signatures,
the conformity to the originals of all of the documents reviewed by us as
copies, including conformed copies, the authenticity and completeness of all
original documents reviewed by us in original or copy form and the legal
competence of each individual executing any document. We have assumed that the
Amendment as filed with the Securities and Exchange Commission will be in
substantially the form of the printer's proof referred to in paragraph (e)
above.

      This opinion is based entirely on our review of the documents listed above
and such investigation of law as we have deemed necessary or appropriate. We
have made no other review or investigation of any kind whatsoever, and we have
assumed, without independent inquiry, the accuracy of the information set forth
in such documents.

      This opinion is limited solely to the internal substantive laws of the
Commonwealth of Massachusetts as applied by courts located in such Commonwealth,
to the extent the same may apply to or govern the transactions covered by this
opinion, except that we express no opinion as to any Massachusetts securities
law.

      We understand that all of the foregoing assumptions and limitations are
acceptable to you.

      Based upon and subject to the foregoing, please be advised that it is our
opinion that:

      1. The Trust is duly organized and existing under the Trust's Declaration
of Trust and the laws of the Commonwealth of Massachusetts as a voluntary
association with transferable shares of beneficial interest commonly referred to
as a "Massachusetts business trust."

      2. The Shares issued on or after May 1, 1998, assuming that they were
issued and sold in accordance with the Trust's Declaration and By-Laws and for
the consideration described in the prior Amendment, were legally issued, fully
paid and non-assessable, and the Shares to be issued, if issued and sold in
accordance with the Trust's Declaration of Trust and By-Laws and for the
consideration described in the Amendment, will be legally issued, fully paid and
non-assessable, except that, as set forth in the statement of additional
information contained in the Prior Amendment and the Amendment, shareholders of
the Fund may under certain circumstances be held personally liable for its
obligations.

      We hereby consent to the filing of this opinion as an exhibit to the
Amendment.

      The opinions expressed herein concern only the effect of the law as
currently in effect and the facts and assumptions described herein. The
undersigned undertakes no obligation to supplement or update this opinion after
the date hereof.

                                    Very truly yours,
   
                                    /s/Bingham Dana LLP
