   INTRODUCTION

   Each Fund is a mutual fund. A mutual fund pools shareholders' money and,
   using professional investment managers, invests it in securities like stocks
   and bonds. Before you invest, you should know a few things about investing in
   mutual funds.

   The value of your investment in a Fund is based on the market prices of the
   securities the Fund holds. These prices change daily due to economic and
   other events that affect securities markets generally, as well as those that
   affect particular companies or governments. These price movements, sometimes
   called volatility, will vary depending on the types of securities a Fund owns
   and the markets where these securities trade.

   LIKE OTHER INVESTMENTS, YOU COULD LOSE MONEY ON YOUR INVESTMENT IN A FUND.
   YOUR INVESTMENT IN A FUND IS NOT A DEPOSIT OR AN OBLIGATION OF SANWA BANK
   CALIFORNIA, ITS AFFILIATES, OR ANY BANK. IT IS NOT INSURED OR GUARANTEED BY
   THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY GOVERNMENT AGENCY.

   Each Fund has its own investment goal and strategies for reaching that goal.
   However, it cannot be guaranteed that a Fund will achieve its goal. Before
   investing, make sure that the Fund's goal matches your own.

   The portfolio manager invests each Fund's assets in a way that the manager
   believes will help the Fund achieve its goal. A manager's judgments about the
   bond and stock markets, economy and companies, and his or her method of
   investment selection, may cause a Fund to underperform other funds with
   similar objectives.

   YIELD

   All mutual funds must use the same formulas to calculate yield and effective
   yield. The Fund typically advertises performance in terms of a 7-day yield
   and 7-day effective yield and may advertise total return. The 7-day yield
   quotation more closely reflects current earnings of the Fund than the total
   return quotation. The 7-day effective yield will be slightly higher than the
   yield because of the compounding effect of the assumed reinvestment. Current
   yields and effective yields fluctuate daily and will vary due to factors such
   as interest rates and the quality, length of maturities, and type of
   investments in the portfolio. The 7-day yield for the period ended December
   31, 1999 was 4.21%.

   You may obtain the most current yield information for the Fund by calling
   (888) 890-8121.

                                                  PRIME MONEY MARKET FUND
   FUND SUMMARY

<TABLE>
    <S>                               <C>
    Investment Goal                   Current income with liquidity and stability of principal
    Investment Focus                  High quality money market instruments
    Principal Investment              Invests in high-quality, short-term debt instruments
    Strategy
    Share Price Volatility            Low
    Investor Profile                  Short-term or risk averse investors seeking current income
                                      from a money market fund that invests in high quality
                                      instruments

    INVESTMENT OBJECTIVE              The Prime Money Market Fund seeks as high a level of current
                                      income as is consistent with maintaining liquidity and
                                      stability of principal.

    INVESTMENT STRATEGY               The Fund invests primarily in U.S. government agency
                                      securities, high-quality commercial paper, short-term
                                      corporate debt obligations, and repurchase agreements. To be
                                      considered high-quality, a security must be rated in one of
                                      the two highest credit quality categories for short-term
                                      securities or, if not rated, determined by the Fund's
                                      Adviser to be of comparable quality. The Fund intends to
                                      maintain an average weighted maturity of not greater than 60
                                      days.

    WHAT ARE THE MAIN RISKS OF        Your investment in the Fund may be subject to the following
    INVESTING IN THIS FUND?           principal risks:
                                      Credit Risk -- Credit risk is the possibility that an issuer
                                      cannot make timely interest and principal payments on its
                                           securities. Because the Fund will only invest in
                                           securities believed to pose minimal credit risk, it is
                                           unlikely that losses due to credit risk will cause a
                                           decline in the value of your investment. However, even
                                           if not severe enough to cause such a decline in
                                           principal value, credit losses could reduce the Fund's
                                           yield. In general, lower-rated securities have higher
                                           credit risks.
                                      Interest Rate Risk -- Interest rate risk involves the
                                      possibility that the Fund's yield will decrease due to a
                                           decline in interest rates.
                                      Net Asset Value Risk -- The risk that the Fund will be
                                      unable to meet its goal of a constant $1 per share.
                                      For more information about these risks please refer to the
                                      section titled "Additional Investment Practices and Risks."
</TABLE>

   AN INVESTMENT IN THE FUND IS NOT A DEPOSIT OR AN OBLIGATION OF SANWA BANK
   CALIFORNIA, ITS AFFILIATES, OR ANY BANK, AND IS NOT INSURED OR GUARANTEED BY
   THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY.
   ALTHOUGH THE FUND SEEKS TO PRESERVE THE VALUE OF YOUR INVESTMENT AT $1 PER
   SHARE, IT IS POSSIBLE TO LOSE MONEY BY INVESTING IN THE FUND.

</TABLE>

   (1) The Lipper Money Market Funds Average is based on an arithmetic average
       of the performance of money market funds as reported by Lipper Inc.

   + The above-quoted performance data includes the performance of a predecessor
     fund for the period before the Prime Money Market Fund commenced operations
     (11/1/97) adjusted to reflect the deduction of fees and expenses applicable
     to the Class A Shares of the Prime Money Market Fund as stated in this
     prospectus in the Fees and Expenses section (i.e., adjusted to reflect
     anticipated fees and expenses, absent any fee waivers). The predecessor
     fund was not registered under the Investment Company Act of 1940 (1940 Act)
     and therefore was not subject to certain investment restrictions,
     limitations and diversification requirements imposed by the 1940 Act and
     the Internal Revenue Code. If the predecessor fund had been registered
     under the 1940 Act, its performance may have been adversely affected. The
     investment objective, restrictions and guidelines of the Prime Money Market
     Fund are substantially similar to its predecessor fund.

   YIELD

   All mutual funds must use the same formulas to calculate yield and effective
   yield. The Fund typically advertises performance in terms of a 7-day yield
   and 7-day effective yield and may advertise total return. The 7-day yield
   quotation more closely reflects current earnings of the Fund than the total
   return quotation. The 7-day effective yield will be slightly higher than the
   yield because of the compounding effect of the assumed reinvestment. Current
   yields and effective yields fluctuate daily and will vary due to factors such
   as interest rates and the quality, length of maturities, and type of
   investments in the portfolio. The 7-day yield for the period ended December
   31, 1999 was 4.82%.

   You may obtain the most current yield information for the Fund by calling

                                      typically higher than that of a money market fund

    INVESTMENT OBJECTIVE              The Investment Grade Bond Fund seeks a high level of income,
                                      consistent with preservation of capital.

    INVESTMENT STRATEGY               The Fund invests in a broad range of fixed income
                                      securities, including U.S. Treasury securities, U.S. agency
                                      securities, mortgage related securities, and corporate
                                      bonds. The Fund will invest at least 80% of its net assets
                                      in bonds which are investment grade securities. To be
                                      considered investment grade, a security must be rated in one
                                      of the four highest credit quality categories or, if not
                                      rated, determined by the Fund's Adviser to be of comparable
                                      quality.

                                      The Adviser uses its proprietary, quantitative security
                                      selection strategy to determine the optimal combination of
                                      investments in the portfolio. Quantitative investment models
                                      and risk management systems assist the Adviser in
                                      identifying the optimal choice of credit rating, maturity,
                                      and coupon rate, among other factors. The Adviser seeks the

                                      relative return premiums, adjusted for risk. Fundamental
                                      valuation, macroeconomic, return and risk measures are all
                                      employed to determine the expected relative return premium
                                      for each sector and/or security. Once the attractiveness of
                                      the various investment sector and individual security
                                      alternatives is determined, the portfolio is constructed so
                                      as to overweight those sectors and/or securities with the
                                      most-favorable prospects, according to the current
                                      quantitative analysis.

                                      The Fund may invest up to 20% of its assets in
                                      non-investment grade debt securities (rated B- and higher),
                                      preferred stocks and convertible securities. In the event
                                      that a security held by the Fund is downgraded, the Fund may
                                      continue to hold such security until such time as the
                                      Adviser deems it to be advantageous to dispose of the
                                      security.

                                      In pursuing its investment objective, the Fund expects that
                                      its portfolio will be characterized by investment risk that
                                      is similar to that of a broadly diversified investment grade
                                      bond portfolio, such as a portfolio structured to match the
                                      Lehman Brothers Aggregate Bond Index or the Salomon Broad
                                      Investment Grade Bond Index. The Fund seeks to maintain a
                                      dollar-weighted average portfolio maturity of five to ten
                                      years.
                                      The Fund may, from time to time, take temporary defensive
                                      positions that are inconsistent with the Fund's principal
                                      investment strategies in attempting to respond to adverse
                                      market, economic, political, or other conditions. In these
                                      and in other cases, the Fund may not achieve its investment
                                      objective.

    WHAT ARE THE MAIN RISKS OF        Loss of money is a risk of investing in the Fund. In
    INVESTING IN THIS FUND?           addition, your investment in the Fund may be subject to the
                                      following principal risks:
                                      Credit Risk -- Credit risk is the possibility that an issuer
                                      cannot make timely interest and principal payments on its
                                           debt obligations, such as bonds. In general,
                                           lower-rated bonds have higher credit risks. However,
                                           because the Fund invests primarily in investment grade
                                           debt obligations, credit risk is minimized.
                                      Interest Rate Risk -- Interest rate risk involves the
                                      possibility that the value of the Fund's investments will
                                           decline due to an increase in interest rates. In
                                           general, the longer a security's maturity, the greater
                                           the interest rate risk.
                                      Prepayment/Call Risk -- Prepayment risk is the chance that
                                      the repayment of mortgages backing a security will occur
                                           sooner than expected. Call risk is the possibility that
                                           during periods of falling interest rates, a bond issuer
                                           will "call" -- or repay -- its high-yielding bond
                                           before the bond's maturity date. In each case, the Fund
                                           may be forced to reinvest in securities with a lower
                                           yield. It may also lose any premium paid for the bond.
                                           Changes in prepayment/call rates can result in greater
                                           price and yield volatility.
                                      The Fund may trade securities actively, which could increase
                                      its transaction costs (thus lowering performance) and may
                                           increase the amount of taxes that you pay.
                                      For more information about these risks please refer to the
                                      section titled "Additional Investment Practices and Risks."

    INVESTMENT OBJECTIVE              The Global Asset Allocation Fund seeks a balance of income

    INVESTMENT STRATEGY               Through the use of a disciplined asset allocation approach,
                                      the Fund intends to invest in, and assume a level of risk
                                      commensurate with, a globally diversified portfolio of
                                      medium (companies with a market value of no less than $250
                                      million) to large capitalization stocks, investment grade
                                      bonds, and cash equivalents. The Adviser will use a variety
                                      of quantitative investment models to identify the country,
                                      sector, and asset classes with the highest expected
                                      risk-adjusted return. Once the relative attractiveness of

                                      portfolio is constructed so as to overweight those
                                      countries, currencies, sectors, and asset classes with the
                                      most favorable prospects, according to the current
                                      quantitative analysis. The Fund seeks to outperform a
                                      blended 70% stock and 30% bond benchmark as part of its
                                      investment approach. The Fund reserves the right to vary its
                                      stock exposure from 50% to 75% of its assets and its bond
                                      exposure from 25% to 50% of its assets.
                                      The Fund will invest in a varying combination of stocks,
                                      bonds, and cash equivalents selected primarily from major
                                      markets such as: the United States, Japan, the U.K.,
                                      Germany, France, Switzerland, Spain, Canada, and Australia.
                                      The Fund may also invest in other markets, including
                                      emerging markets. By diversifying across countries,
                                      currencies, and asset classes (stocks and bonds), the Fund
                                      pursues its capital appreciation goals while seeking to
                                      control portfolio risk. The Fund will normally invest at
                                      least 65% of its net assets in securities representing at
                                      least three different countries, including the United
                                      States.
                                      The Fund's equity exposure typically will not deviate by
                                      more than 20% from the market capitalization weights of the
                                      respective individual equity markets as determined by that
                                      market's representation in the Salomon Smith Barney Primary
                                      Market Index -- World or the Morgan Stanley Capital
                                      International World Index. For example, if the Japanese
                                      equity market represents 30% of the Salomon Smith Barney
                                      Primary Market Index -- World, then Japanese equities will
                                      typically represent not less than 10% nor more than 50% of
                                      the Fund's equity exposure.
                                      Bonds in the Fund's portfolio are expected to range in
                                      maturity from one to thirty years. The Fund's bond portfolio
                                      will seek to maintain a risk level, yield, maturity and
                                      other characteristics commensurate with that of the Lehman
                                      Brothers U.S. Treasury Index.
                                      In order to execute its strategy in an efficient manner, the
                                      Adviser may utilize equity index, bond index, and currency
                                      futures contracts in the various countries. The Fund may use

                                      efficient means of achieving broad market exposure to the
                                      stock, fixed income and currency markets of a particular
                                      country, to provide liquidity, and to facilitate asset
                                      allocation shifts.
                                      The Fund may, from time to time, take temporary defensive
                                      positions that are inconsistent with the Fund's principal
                                      investment strategies in attempting to respond to adverse
                                      market, economic, political, or other conditions. In these
                                      and in other cases, the Fund may not achieve its investment

    WHAT ARE THE MAIN RISKS OF        Loss of money is a risk of investing in the Fund. In
    INVESTING IN THIS FUND?           addition, your investment in the Fund may be subject to the
                                      following principal risks:
                                      Foreign Securities Risk -- Investing in foreign markets
                                      involves greater risk than investing in the United States.
                                           Foreign securities may be affected by such factors as
                                           fluctuations in currency exchange rates, incomplete or
                                           inaccurate financial information on companies, social
                                           upheavals and political actions ranging from tax code
                                           changes to governmental collapse. Emerging market
                                           securities may be even more susceptible to these risks.
                                      Market Risk -- Market risk is the possibility that the
                                      Fund's investments in equity securities will decline because
                                           of drops in the stock market. Stock markets tend to
                                           move in cycles, with periods of either rising or
                                           falling prices. The value of your investment will go up
                                           or down in response to these movements.
                                      Investment Style Risk -- Investment style risk is the
                                      possibility that returns from medium to large capitalization
                                           stocks will trail returns from other asset classes or
                                           the overall stock market.
                                      Credit Risk -- Credit risk is the possibility that an issuer
                                      cannot make timely interest and principal payments on its
                                           debt obligations, such as bonds. In general,
                                           lower-rated bonds have higher credit risks.
                                      Interest Rate Risk -- Interest rate risk involves the
                                      possibility that the value of the Fund's investments will
                                           decline due to an increase in interest rates. In
                                           general, the longer a security's maturity, the greater
                                           the interest rate risk.
                                      The Fund may trade securities actively, which could increase
                                      its transaction costs (thus lowering performance) and may
                                           increase the amount of taxes that you pay.
                                      For more information about these risks please refer to the

    INVESTMENT OBJECTIVE              The Equity Fund seeks long-term capital growth.

    INVESTMENT STRATEGY               The Fund attempts to identify medium (companies with a
                                      market value of no less than $250 million) to large
                                      capitalization stocks of both undervalued companies and
                                      growth companies using a quantitative securities selection
                                      process. The Fund intends to invest at least 65% of its net
                                      assets in the common stocks of corporations representing a
                                      broad cross section of the U.S. economy. Common stocks are
                                      chosen based upon the Adviser's quantitative stock selection
                                      models which rank a universe of approximately 1,000 U.S.
                                      common stocks according to their valuation, growth, return,
                                      and risk measures. The stocks assigned the highest ratings
                                      are those deemed to have a greater potential for price
                                      appreciation over a short-to-intermediate term horizon.

                                      The portfolio is constructed so that the aggregate
                                      investment characteristics of the Fund are similar to those
                                      of the S&P 500 Index. These characteristics include such
                                      measures as weighted average market value, economic sector
                                      diversification, P/E ratio, dividend yield, and market
                                      "beta" (or sensitivity). However, while maintaining
                                      aggregate investment characteristics similar to those of the
                                      S&P 500 Index, the Fund seeks to invest in individual common
                                      stocks -- including stocks which may not be part of that
                                      Index -- which the Adviser believes hold a greater potential
                                      for price appreciation. As of the date of this Prospectus,
                                      the S&P 500 Index statistics were as follows: the weighted
                                      average market value was $143 billion, the mean market value
                                      was $25 billion, the smallest company had a market value of
                                      $361 million, and the largest company had a market value of
                                      $602 billion.

                                      Although the Fund normally intends to be fully invested in
                                      common stocks, it may invest temporarily in certain
                                      short-term fixed income securities, investment company
                                      securities, and money market instruments. Such securities
                                      may be used to invest uncommitted cash balances or to
                                      maintain liquidity in order to meet shareholder redemptions.

                                      The Fund may, from time to time, take temporary defensive
                                      positions that are inconsistent with the Fund's principal
                                      investment strategies in attempting to respond to adverse
                                      market, economic, political, or other conditions. In these
                                      and in other cases, the Fund may not achieve its investment
                                      objective.

    WHAT ARE THE MAIN RISKS OF        Loss of money is a risk of investing in the Fund. In
    INVESTING IN THIS FUND?           addition, your investment in the Fund may be subject to the
                                      following principal risks:

                                      Market Risk -- Market risk is the possibility that the
                                      Fund's investments in equity securities will decline because
                                           of drops in the stock market. Stock markets tend to
                                           move in cycles, with periods of either rising or
                                           falling prices. The value of your investment will go up
                                           or down in response to these movements.

                                      Investment Style Risk -- Investment style risk is the
                                      possibility that returns from medium to large capitalization
                                           stocks will trail returns from other asset classes or
                                           the overall stock market.

                                      The Fund may trade securities actively, which could increase
                                      its transaction costs (thus lowering performance) and may
                                           increase the amount of taxes that you pay.

                                      For more information about these risks please refer to the
                                      section titled "Additional Investment Practices and Risks."

 SHAREHOLDER INFORMATION

   DISTRIBUTION/SERVICE (12B-1) FEES AND SHAREHOLDER SERVICING FEES

   The Funds have adopted a Distribution and Shareholder Services Plan under
   Rule 12b-1 that allows Class A shares of each Fund to pay distribution and
   service fees for the sale and distribution of its shares and for services
   provided to shareholders. The Funds have also adopted a Service Plan that
   allows Class A shares of each Fund to compensate financial institutions for
   providing shareholder services to their customers and account holders.
   Because these fees are paid out of a Fund's assets continuously, over time
   these fees will increase the cost of your investment and may cost you more
   than paying other types of sales charges. The maximum distribution/service
   (12b-1) fee is 0.25% of the average daily net assets of Class A shares of a
   Fund. The maximum shareholder servicing fee is 0.25% of the average daily net
   assets of Class A shares of a Fund.

   Over time shareholders may pay more than the equivalent of the maximum
   permitted front-end sales charge under the NASD rules because distribution
   and service fees are paid out of a Fund's assets on an ongoing basis.

   MULTIPLE CLASS STRUCTURE

   The Eureka Funds offer two classes of shares: Class A shares and Trust
   shares. Class A shares are offered to the general public and are subject to a
   distribution/ service (12b-1) fee and a shareholder servicing fee. Trust
   shares are offered to Sanwa Bank California and its affiliates and certain
   other financial service providers approved by the Distributor. Trust shares
   are not subject to a distribution/service (12b-1) fee or a shareholder
   servicing fee.

   OPENING AN ACCOUNT

   1. Read this prospectus carefully.

   2. Determine how much you want to invest. The minimum investment for the
      Eureka Funds is as follows:

        -  INITIAL PURCHASE:  $1,000 for each Fund

        -  ADDITIONAL PURCHASES:  $50 for each Fund

           The minimum initial investment amount is $50 if purchases are made in
           connection with qualified retirement plans (401(k) and 403(b)
           accounts only), systematic investment plans or payroll deduction
           plans.

           A Fund may waive its minimum purchase requirement. The Distributor
           may reject an order if it is considered to be in the best interest of
           the Fund.

   3. Complete the appropriate parts of the Account Registration Form, carefully
      following the instructions. You must submit additional documentation when
      opening trust, corporate or power of attorney accounts. For additional
      information or for an Account Registration Form, please contact your local
      Sanwa Bank California office or call Eureka Funds at (888) 890-8121.

 SHAREHOLDER INFORMATION

                              GENERAL POLICIES ON SELLING SHARES

   SELLING SHARES IN WRITING. In certain circumstances, you may need to include
   a signature guarantee, which protects you against fraudulent orders. You will
   need a signature guarantee unless:

   - the redemption check is payable to the shareholder(s) of record, and

   - the check is mailed to the shareholder(s) of record and mailed to the
     address of record.

   You should be able to obtain your signature guarantee from a bank, broker,
   dealer, credit union, securities exchange or association, clearing agency, or
   savings association. A notary public CANNOT provide a signature guarantee.

   RECEIVING YOUR MONEY. Normally, payment of your redemption proceeds will be
   made as promptly as possible and, in any event, within seven calendar days
   after the redemption order is received. At various times, however, a Fund may
   be requested to redeem shares for which it has not yet received good payment;
   collection of payment may take fifteen days or more. If you have made your
   initial investment by check, you cannot receive the proceeds of that check
   until it has cleared. You can avoid this delay by purchasing shares with a
   certified check or wire transfer.

   INVOLUNTARY SALES OF YOUR SHARES. Due to the relatively high costs of
   handling small investments, each Fund reserves the right to redeem your
   shares at net asset value if your account balance drops below $1,000 due to
   redemptions. Before a Fund exercises its right to redeem your shares, you
   will be given 60 days written notice to give you time to increase the value
   of your account to at least $1,000.

   POSTPONEMENT OF REDEMPTION REQUEST. The Funds may postpone payment for shares
   at times when the New York Stock Exchange is closed or under any emergency
   circumstances as determined by the Securities and Exchange Commission. If you
   experience difficulty making a telephone redemption during periods of drastic
   economic or market change, you can send the Funds your request by regular or
   express mail. Follow the instructions above under "Selling Your Shares" in
   this section.

   REDEMPTION IN KIND. The Funds reserve the right to make payment in securities
   rather than cash, known as a "redemption in kind." This could occur under
   extraordinary circumstances, such as a very large redemption that could
   affect Fund operations (for example, more than 1% of a Fund's net assets). If
   the Fund deems it advisable for the benefit of all shareholders, redemption
   in kind will consist of securities equal in market value to your shares. When
   you convert these securities to cash, you will pay brokerage charges.

   UNDELIVERABLE REDEMPTION CHECKS. For any shareholder who chooses to receive
   distributions in cash: If distribution checks (1) are returned and marked as
   "undeliverable" or (2) remain uncashed for six months, your account will be
   changed automatically so that all future distributions are reinvested in your
   account. Checks that remain undeliverable or uncashed for six months will be
   canceled and will be redeposited in your account at the current net asset
   value.

                              EXCHANGING SHARES
   HOW TO EXCHANGE YOUR SHARES. Class A Shares of each Fund may be exchanged for
   Class A Shares of the other Funds, provided that the Shareholder making the
   exchange is eligible on the date of the exchange to purchase Class A Shares
   (with certain exceptions and subject to the terms and conditions described in
   this prospectus). Class A Shares of each Fund may be exchanged for Trust
   Shares in instances where the Shareholder becomes eligible to purchase Trust
   Shares.

   A shareholder wishing to exchange Class A Shares purchased through a
   financial adviser or brokerage account may do so by contacting their adviser
   or broker. A fee may be charged by the adviser or broker with regard to such
   an exchange. Information about such charges will be supplied by your adviser
   or broker.

   The exchange will be made on the basis of the relative net asset value of the
   shares exchanged.

   An exchange from one Fund to another Fund is considered a sale of shares and
   will result in a capital gain or loss for federal income tax purposes.

   Any shareholder who wishes to make an exchange must have received a current
   Prospectus of the Fund in which he or she wishes to invest before the
   exchange will be effected.

   A shareholder wishing to exchange Class A Shares purchased directly from the
   Eureka Funds may do so by contacting the Eureka Funds at (888) 890-8121 or by
   providing written instructions to the Eureka Funds, P.O. Box 182792,
   Columbus, Ohio 43218-2792 with the following information:

   - your name and telephone number;
   - the exact account name and account number;
   - the taxpayer identification number;
   - the dollar value or number of shares to be exchanged;
   - the name of the Fund from which the exchange is to be made; and
   - the name of the Fund into which the exchange is to be made. If the exchange
     will be made into an existing account, please provide the account number.

   If not selected on the Account Registration Form, the Shareholder will
   automatically receive exchange privileges.

   The Funds reserve the right to change the terms of the exchange privilege
   upon sixty days' written notice.

   The Funds are not intended to serve as vehicles for frequent trading in
   response to short-term fluctuations in the market. Due to the disruptive
   effect that excessive trading can have on efficient portfolio management, the
   Funds have established a policy of limiting exchange activity to four
   substantive exchange redemptions from a Fund during any calendar year. Other
   than exchanges pursuant to the Eureka Funds' Auto Exchange Plan, there is a
   $500 minimum for exchanges.

                              PRICING OF FUND SHARES
   VALUATION OF SHARES. The price of a Fund's shares is based on the Fund's net
   asset value. The net asset value of a Fund is determined by dividing the
   total market value of the Fund's investments and other assets, less any
   liabilities, by the total number of outstanding shares of the Fund. The net
   asset value is calculated separately for the Trust shares and the Class A
   shares of each Fund.

   The net asset value for each Fund (except the Money Market Funds) may be
   found daily in The Wall Street Journal and other newspapers.

                              ADDITIONAL INVESTOR SERVICES

   AUTO INVEST PLAN (AIP). AIP lets you set up periodic additional investments
   in the Funds of your choice through automatic deductions from your bank
   account. The minimum investment amount is $50 per Fund and the minimum
   subsequent investment amount is $50 per Fund. Investments may be made
   bi-monthly, monthly, or quarterly. To establish, complete the appropriate
   section in the Account Registration Form. To participate in AIP from your
   bank account, please attach a voided check to your Account Registration Form.

   CHECK WRITING SERVICE. Shareholders of Class A Shares of a Money Market Fund
   may write checks in the amount of $500 or more against their Fund account.
   You will receive a supply of checks after a signed signature card is
   received. A check may be made payable to any person, and your account will
   continue to earn dividends until the check clears. Because of the difficulty
   of determining in advance the exact value of a Fund account, you may not use
   a check to close your account. The Eureka Funds reserve the right to charge
   your account a fee for stopping payment of a check upon your request or if
   the check cannot be honored because of insufficient funds or other valid
   reasons.

   AUTO EXCHANGE. Eureka Funds Auto Exchange enables you to make regular,
   automatic withdrawals from Class A Shares of a Money Market Fund and use
   those proceeds to benefit from dollar-cost-averaging by automatically making
   purchases of shares of another Eureka Fund. With your authorization, the
   Transfer Agent will withdraw the amount specified (subject to the applicable
   minimums) from your Money Market Fund account and will automatically invest
   that amount in Class A Shares of the Fund you designate. In order to
   participate in the Auto Exchange, you must have a minimum beginning balance
   of $10,000 in your Money Market Fund account; you will still be subject to
   minimum account balance requirements as described below.

   To participate in the Auto Exchange, complete the appropriate section of the
   Account Registration Form, which can be acquired by calling the Funds at
   (888)890-8121. To change the Auto Exchange instructions or to discontinue the
   feature, a shareholder must send a written request to the Eureka Funds, P.O.
   Box 182792, Columbus, Ohio 43218-2792. The Auto Exchange may be amended or
   terminated without notice at any time.

   AUTO WITHDRAWAL PLAN (AWP). If you have at least $10,000 in the Fund selected
   and maintain a minimum account balance of $1,000 in the Fund, you may use
   AWP, which allows you to receive regular distributions from your account.
   Under the plan you may elect to receive automatic payments via check of at
   least $100 per Fund or more on a monthly basis. You may arrange to receive
   regular distributions from your account and have the amount transferred
   according to your instructions by completing the appropriate section in the
   Account Registration Form or by submitting a written request (with signature
   guarantee) to the Funds. To change the AWP instructions or to discontinue the
   feature, the request must be made in writing to the Eureka Funds, P.O. Box
   182792, Columbus, Ohio 43218-2792. The AWP may be amended or terminated,
   without notice, at any time.

 SHAREHOLDER INFORMATION

                              DIVIDENDS AND DISTRIBUTIONS

   As a mutual fund shareholder, you may receive capital gains and/or income
   from your investment. The Money Market Funds and the Investment Grade Bond
   Fund declare dividends daily and pay income dividends monthly. The Global
   Asset Allocation Fund declares and pays income dividends annually. The Equity
   Fund declares and pays income dividends monthly. The Money Market Funds do
   not expect to realize any capital gains. However, if capital gains are
   realized, the Money Market Funds will distribute such gains at least once a
   year. The Investment Grade Bond Fund, the Global Asset Allocation Fund, and
   the Equity Fund each distribute capital gains, if any, at least once a year.

   We will automatically reinvest any income dividends and capital gains
   distributions you are entitled to in additional shares of your Fund(s) unless
   you notify the Funds that you want to receive your distributions in cash. To
   do so, select the cash option on your application or to change your existing
   account, send a letter with your request, including your name and account
   number to:

                                   Eureka Funds
                                  P.O. Box 182792
                             Columbus, Ohio 43218-2792

   Your request will become effective for distributions having record dates
   after our Distributor receives your request. Note that the Internal Revenue
   Service treats dividends paid in additional Fund shares the same as it treats
   dividends paid in cash.    TAXES

   Your mutual fund investments may have a considerable impact on your tax
   situation. We've summarized some of the main points you should know below.
   Note, however, that the following is general information and will not apply
   to you if you are investing through a tax-deferred account such as an IRA or
   a qualified employee benefit plan. In addition, if you are not a resident of
   the United States, you may have to pay taxes besides those described here,
   such as U.S. withholding and estate taxes.

   We will send you a statement each year showing the tax status of all your
   distributions. The laws governing taxes change frequently, however, so please
   consult your tax adviser for the most up-to-date information and specific
   guidance regarding your particular tax situation. You can find more
   information about the potential tax consequences of mutual fund investing in
   our Statement of Additional Information.

   Note that you may have to pay taxes on Fund distributions whether you
   received them in the form of cash or additional Fund shares. The Internal
   Revenue Service treats most mutual fund distributions as ordinary income. One
   exception is long-term capital gains, which are typically taxed at a lower
   rate than ordinary income when distributed to shareholders who are
   individuals regardless of how long such shareholders have held their Fund
   shares.

                              [Logo]
 SHAREHOLDER INFORMATION

   TAXES ON FUND DISTRIBUTIONS. You may owe taxes on Fund distributions even if
   they represent income or capital gains the Fund earned before you invested in
   it (if such income or capital gains were included in the price you initially
   paid for your shares).

   STATE, LOCAL, AND FOREIGN TAXES. In addition to federal taxes, you may have
   to pay state, local, and foreign taxes on the dividends or capital gains, if
   any, you receive from a Fund, as well as on capital gains, if any, you
   realized from selling or exchanging Fund shares.

   DIVIDENDS AND SHORT-TERM CAPITAL GAINS. The Internal Revenue Service treats
   any dividends and short-term capital gains you receive from the Funds as
   ordinary income.

   FUNDS INVESTING IN FOREIGN SECURITIES: If your Fund invests in foreign
   securities, the income those securities generate may be subject to foreign
   withholding taxes, which may decrease their yield. Foreign governments may
   also impose taxes on other payments or gains your Fund earns on these
   securities. In general, shareholders in these Funds will not be entitled to
   claim a credit or deduction for these foreign taxes on their U.S. tax return.
   (There are some exceptions, however; please consult your tax adviser for more
   information.) In addition, foreign investments may prompt a Fund to
   distribute ordinary income more frequently and/or in greater amounts than
   purely domestic funds, which could increase your tax liability.

   TAX CONSEQUENCES OF SELLING OR EXCHANGING SHARES. If you sell or exchange
   Fund shares, you may have to report capital gains, if any, you realize as
   income and any capital loss as a deduction on your federal income tax return.
   For more specific information about your own tax situation, consult your tax
   adviser.

   The portfolio managers of the Funds do not actively consider tax consequences
   when making investment decisions. From time to time, the Funds may realize
   capital gains as by-products of ordinary investment activities. As a result,
   the amount and timing of Fund distributions may vary considerably from year
   to year.

    AVOID 31% TAX WITHHOLDING. If you have not done so already, be sure to
    provide us with your correct taxpayer identification number OR certify that
    it is correct. Unless we have that information, the Funds may be required,
    by law, to withhold 31% of the taxable distributions you would otherwise be
    entitled to receive from your Fund investments as well as any proceeds you
    would normally receive from selling Fund shares.

   THESE TAX CONSIDERATIONS MAY OR MAY NOT APPLY TO YOU. PLEASE CONSULT YOUR TAX
   ADVISER TO DETERMINE WHETHER THESE CONSIDERATIONS ARE RELEVANT TO YOUR
   PARTICULAR INVESTMENTS AND TAX SITUATION. MORE INFORMATION ABOUT TAXES CAN BE
   FOUND IN THE STATEMENT OF ADDITIONAL INFORMATION.

</TABLE>

                               PRIOR PERFORMANCE OF THE ADVISER

   The following tables set forth the Adviser's composite performance data
   relating to the historical performance of all collective investment trusts
   and common trust funds managed by the Adviser, since the dates indicated,
   that have investment objectives, policies, strategies and risks substantially
   similar to those of the Equity Fund and the Investment Grade Bond Fund. The
   data is provided to illustrate the past performance of the Adviser in
   managing substantially similar accounts as measured against a specified
   market index or indices and does not represent the performance of the Equity
   Fund and the Investment Grade Bond Fund. Investors should not consider this
   performance data as an indication of future performance of the Equity Fund
   and the Investment Grade Bond Fund or of the Adviser.

   The Adviser's composite performance data shown below were calculated on a
   total return basis and include all dividends and interest, accrued income and
   realized and unrealized gains and loses. All returns reflect the deduction of
   investment advisory fees, brokerage commissions and execution costs paid by
   the Adviser's institutional private accounts, without provision for federal
   or state income taxes. Custodial fees, if any, were not included in the
   calculation. The Adviser's composites include all actual, fee-paying,
   discretionary institutional, private accounts managed by the Adviser that
   have investment objectives, policies, strategies and risks substantially
   similar to those of the Equity Fund and the Investment Grade Bond Fund.
   Securities transactions are accounted for on the trade date and accrual
   accounting is utilized. Cash and equivalents are included in performance
   returns. The monthly returns of the Adviser's composites combine the
   individual accounts' returns by asset-weighting each individual account's
   asset value as of the beginning of the month. Yearly returns are calculated
   by geometrically linking the monthly returns.

   The institutional private accounts that are included in the Adviser's
   composites are not subject to the same types of expenses to which the Equity
   Fund and Investment Grade Bond Fund are subject nor to the diversification
   requirements, specific tax restrictions and investment limitations imposed on
   the Funds by the 1940 Act or Subchapter M of the Internal Revenue Code.
   Consequently, the performance results for the Adviser's composites could have
   been adversely affected if the institutional private accounts included in the
   composites had been regulated as investment companies under the federal
   securities laws. In addition, the performance results for the Adviser's
   composites would have been lower if the expenses to which the Equity Fund and
   the Investment Grade Bond Fund are subject were applied.

 INVESTMENT MANAGEMENT

   The results presented below may not necessarily equate with the return
   experienced by any particular investor as a result of the timing of
   investments and redemptions. In addition, the effect of taxes on any investor
   will depend on such person's tax status, and the results have not been
   reduced to reflect any income tax which may have been payable.

   The investment results of the Adviser's composites presented below are
   unaudited and are not intended to predict or suggest the returns that might
   be experienced by the Equity Fund and Investment Grade Bond Fund or an
   individual investor investing in such Funds. The investment results of the
   Adviser's composites were not calculated pursuant to the methodology
   established by the SEC that will be used to calculate the performance results
   of the Funds. Investors should also be aware that the use of a methodology
   different from that used below to calculate performance could result in
   different performance data.

   All information set forth in the tables below relies on data supplied by the
   Adviser or from statistical services, reports or other sources believed by
   the Adviser to be reliable. However, except as otherwise indicated, such
   information has not been verified and is unaudited.

   The financial highlights table is intended to help you understand the
   financial performance of the Class A Shares of each Fund for the period from
   commencement of operations on February 3, 1998 through September 30, 1999.
   Certain information reflects financial results for a single Fund share. The
   total returns in the table represent the rate that an investor would have
   earned or lost on an investment in the Fund (assuming reinvestment of all
   dividends and distributions). This information has been audited by Ernst &
   Young LLP, whose report, along with the Fund's financial statements, are
   included in the annual report, which is available upon request.

   (1)    Each Fund has a fundamental investment policy regarding these
          practices or securities, as set forth in the Statement of Additional
          Information, which may in some cases be less restrictive than the
          operating policy set forth in the chart.

   (2)    The Money Market Funds may invest in these securities only if
          consistent with their objectives and Rule 2a-7.

   (3)    Each Fund's liquidity limit is calculated as a percentage of its net
          assets.

   (4)    Reverse repurchase agreements would also be subject to a Fund's policy
          on borrowings.

   (5)    Relative to other securities, these securities are more likely to be
          deemed illiquid and, therefore, may be subject to the restrictions on
          illiquid securities.

 ADDITIONAL INVESTMENT PRACTICES AND RISKS

                                 INVESTMENT RISKS

   Below is a more complete discussion of the types of risks inherent in the
   securities and investment techniques listed above as well as those risks
   discussed in "What are the main risks of investing in this Fund?" Because of
   these risks, the value of the securities held by each Fund may fluctuate, as
   will the value of your investment in the Fund. Certain investments and Funds
   are more susceptible to these risks than others.

   CORRELATION RISK.  The risk that changes in the value of a hedging instrument
   will not match those of the asset being hedged (hedging is the use of one
   investment to offset the effects of another investment). Incomplete
   correlation can result in unanticipated risks and volatility.

   CREDIT RISK.  The risk that the issuer of a security, or the counterparty to
   a contract, will default or otherwise become unable to honor a financial
   obligation.

   CURRENCY RISK.  The risk that fluctuations in the exchange rates between the
   U.S. dollar and foreign currencies may negatively affect an investment.
   Adverse changes in exchange rates may erode or reverse any gains produced by
   foreign currency denominated investments and may widen any losses.

   FOREIGN INVESTMENT RISK.  The risk associated with higher transaction costs,
   delayed settlements, currency controls and adverse economic developments.
   This also includes the risk that fluctuations in the exchange rates between
   the U.S. dollar and foreign currencies may negatively affect an investment.
   Adverse changes in exchange rates may erode or reverse any gains produced by
   foreign currency denominated investments and may widen any losses. Exchange
   rate volatility also may affect the ability of an issuer to repay U.S. dollar
   denominated debt, thereby increasing credit risk. Foreign securities may also
   be affected by incomplete or inaccurate financial information on companies,
   social upheavals or political actions ranging from tax code changes to
   governmental collapse. These risks are more significant in emerging markets.

   INFORMATION RISK.  The risk that key information about a security or market
   is inaccurate or unavailable.

   INTEREST RATE RISK.  The risk of market losses attributable to changes in
   interest rates. With fixed-rate securities, a rise in interest rates
   typically causes a fall in values, while a fall in rates typically causes a
   rise in values.

   LEVERAGE RISK.  The risk associated with securities or practices (such as
   borrowing) that multiply small index or market movements into large changes
   in value. Leverage is often associated with investments in derivatives, but
   also may be embedded directly in the characteristics of other securities.

        - HEDGED.  When a derivative (a security whose value is based on another
          security or index) is used as a hedge against an opposite position
          that the Fund also holds, any loss generated by the derivative should
          be substantially offset by gains on the hedged investment, and vice
          versa. Hedges are sometimes subject to imperfect matching between the
          derivative and underlying security, and there can be no assurance that
          a Fund's hedging transactions will be effective.

        - SPECULATIVE.  To the extent that a derivative is not used as a hedge,
          the Fund is directly exposed to the risks of that derivative. Gains or
          losses from speculative positions in a derivative may be substantially
          greater than the derivatives original cost.

 ADDITIONAL INVESTMENT PRACTICES AND RISKS

   LIQUIDITY RISK.  The risk that certain securities may be difficult or
   impossible to sell at the time and the price that would normally prevail in
   the market. The seller may have to lower the price, sell other securities
   instead or forego an investment opportunity, any of which could have a
   negative effect on Fund management or performance. This includes the risk of
   missing out on an investment opportunity because the assets necessary to take
   advantage of it are tied up in less advantageous investments.

   MANAGEMENT RISK.  The risk that a strategy used by a Fund's portfolio manager
   may fail to produce the intended result. This includes the risk that changes
   in the value of a hedging instrument will not match those of the asset being
   hedged. Incomplete matching can result in unanticipated risks. This risk is
   common to all mutual funds.

   MARKET RISK.  The risk that the market value of a security may move up and
   down, sometimes rapidly and unpredictably. These fluctuations may cause a
   security to be worth less than the price originally paid for it, or less than
   it was worth at an earlier time. Market risk may affect a single issuer,
   industrial sector of the economy or the market as a whole. There is also the
   risk that the current interest rate may not accurately reflect existing
   market rates. A rise in interest rates typically causes a fall in values,
   while a fall in rates typically causes a rise in values. Finally, key
   information about a security or market may be inaccurate or unavailable.

   OPPORTUNITY RISK.  The risk of foregoing an investment opportunity because
   the assets necessary to take advantage of it are tied up in less advantageous
   investments.

   POLITICAL RISK.  The risk of losses attributable to governmental or political
   actions, from changes in tax or trade statutes to governmental collapse and
   war. There are also risks in particular to investing in foreign securities,
   including higher transaction costs, delayed settlements, currency controls
   and adverse economic developments.

   PRE-PAYMENT RISK.  The risk that the principal repayment of a security will
   occur sooner than expected and will effect the rate of return on
   mortgage-backed securities and may result in greater price and yield
   volatility and possible investment losses. When mortgage obligations are
   pre-paid, a Fund may have to reinvest in securities with a lower yield.
   During periods of declining interest rates, prepayment rates can be expected
   to accelerate. Under certain interest rate and prepayment rate scenarios, a
   Fund may fail to recoup any premium paid on mortgage-related securities
   notwithstanding a direct or indirect governmental or agency guarantee.

   TAX RISK.  The risk that the issuer of tax-exempt securities will fail to
   comply with certain requirements of the Internal Revenue Code, which could
   cause interest income to be retroactively included in gross income.

   VALUATION RISK.  The risk that a Fund has valued certain of its securities at
   a higher price than it can sell them for.

   PORTFOLIO TURNOVER.  High portfolio turnover rates will generally result in
   higher transaction costs to a Fund and may increase the taxes payable by a
   Fund's shareholders.

                       STATEMENT OF ADDITIONAL INFORMATION

                                  EUREKA FUNDS

         Eureka Funds is an open-end management investment company. The Eureka
Funds consist of five series of units of beneficial interest ("Shares") offered
to the public, each representing interests in one of five separate investment
portfolios: the Eureka U.S. Treasury Obligations Fund (the "U.S. Treasury
Obligations Fund"), the Eureka Prime Money Market Fund (the "Prime Money Market
Fund" and together with the U.S. Treasury Obligations Fund, the "Money Market
Funds"), the Eureka Investment Grade Bond Fund (the "Investment Grade Bond
Fund"), the Eureka Global Asset Allocation Fund (the "Global Asset Allocation
Fund"), and the Eureka Equity Fund (the "Equity Fund" and together with the
Investment Grade Bond Fund and the Global Asset Allocation Fund, the "Variable
NAV Funds"). Each Fund offers to the public two classes of Shares: Class A
Shares and Trust Shares. Most information contained in this Statement of
Additional Information expands on subjects discussed in the Prospectuses.
Capitalized terms not defined herein are defined in the Prospectuses. An
investment in Shares of a Fund should not be made without first reading the
applicable Prospectus.


                        INVESTMENT OBJECTIVE AND POLICIES

ADDITIONAL INFORMATION ON PORTFOLIO INSTRUMENTS

         The following policies supplement the information pertaining to
portfolio instruments of each Fund as set forth in the Prospectuses.

         The Appendix to this Statement of Additional Information identifies
nationally recognized statistical ratings organizations ("NRSROs") that may be
used by Sanwa Bank California, the Eureka Funds' investment adviser ("SBCL"),
with regard to portfolio investments for the Funds and provides a description of
relevant ratings assigned by each such NRSRO. A rating by an NRSRO may be used
only where the NRSRO is neither controlling, controlled by, nor under common
control with the issuer of, or any issuer, guarantor, or provider of credit
support for, the instrument.

         ASSET-BACKED SECURITIES. Each Fund, except the U.S. Treasury
Obligations Fund, may invest in asset-backed securities. The Prime Money Market
Fund and the Investment Grade Bond Fund may each invest up to 100% of their
total assets, and the Global Asset Allocation Fund and the Equity Fund may each
invest up to 35% of their total assets in asset-backed securities.

         Asset-backed securities are secured by company receivables, home equity
loans, truck


                                      B-1
<PAGE>   57

or auto loans, leases, credit card receivables and other securities backed by
receivables or assets.

         Offerings of Certificates for Automobile Receivables ("CARS") are
structured either as flow-through grantor trusts or as pay-through notes. CARS
structured as flow-through instruments represent ownership interests in a fixed
pool of receivables. CARS structured as pay-through notes are debt instruments
supported by the cash flows from the underlying assets. CARS may also be
structured as securities with fixed payment schedules which are generally issued
in multiple-classes. Cash-flow from the underlying receivables is directed first
to paying interest and then to retiring principal via paying down the two
respective classes of notes sequentially. Cash-flows on fixed-payment CARS are
certain, while cash-flows on other types of CARS issues depends on the
prepayment rate of the underlying automobile loans. Prepayments of automobile
loans are triggered mainly by automobile sales and trade-ins. Many people buy
new cars every two or three years, leading to rising prepayment rates as a pool
becomes more seasoned.

         Certificates for Amortizing Revolving Debt ("CARDS") represent
participation in a fixed pool of credit card accounts. CARDS pay "interest only"
for a specified period. The CARDS principal balance remains constant during this
period, while any cardholder repayments or new borrowings flow to the issuer's
participation. Once the principal amortization phase begins, the balance
declines with paydowns on the underlying portfolio. Cash flows on CARDS are
certain during the interest-only period. After this initial interest-only
period, the cash flow will depend on how fast cardholders repay their
borrowings. Historically, monthly cardholder repayment rates have been
relatively fast. As a consequence, CARDS amortize rapidly after the end of the
interest-only period. During this amortization period, the principal payments on
CARDS depend specifically on the method for allocating cardholder repayments to
investors. In many cases, the investor's participation is based on the ratio of
the CARDS' balance to the total credit card portfolio balance. This ratio can be
adjusted monthly or can be based on the balances at the beginning of the
amortization period. In some issues, investors are allocated most of the
repayments, regardless of the CARDS' balance. This method results in especially
fast amortization.

         Credit support for asset-backed securities may be based on the
underlying assets or provided by a third party. Credit enhancement techniques
include letters of credit, insurance bonds, limited guarantees (which are
generally provided by the issuer), senior-subordinated structures and over
collateralization.

         BANKERS' ACCEPTANCES, CERTIFICATES OF DEPOSIT, DEMAND AND TIME
DEPOSITS. Each Fund, except the U.S. Treasury Obligations Fund, may invest in
bankers' acceptances, certificates of deposit, and demand and time deposits. The
Prime Money Market Fund may invest up to 25% of its total assets, and the
Investment Grade Bond Fund, the Global Asset Allocation Fund, and the Equity
Fund may each invest up to 35% of their total assets in


                                      B-2
<PAGE>   58

bankers' acceptance. For temporary defensive purposes, the Investment Grade Bond
Fund, the Global Asset Allocation Fund, and the Equity Fund may each invest up
to 100% of their total assets in bankers' acceptance and certificates of
deposit. The Prime Money Market Fund may invest up to 100% of its total assets,
and the Investment Grade Bond Fund, the Global Asset Allocation Fund, and the
Equity Fund may each invest up to 35% of their total assets in certificates of
deposit and time deposits. For temporary defensive purposes, the Investment
Grade Bond Fund, the Global Asset Allocation Fund, and the Equity Fund may each
invest up to 100% of their total assets in time deposits.

         Bankers' acceptances are negotiable drafts or bills of exchange
typically drawn by an importer or exporter to pay for specific merchandise,
which are "accepted" by a bank, meaning, in effect, that the bank
unconditionally agrees to pay the face value of the instrument on maturity.
Certificates of deposit are negotiable certificates issued against funds
deposited in a commercial bank or a savings and loan association for a definite
period of time and earning a specified return.

         Bankers' acceptances will be those guaranteed by domestic and foreign
banks, if at the time of investment such banks have capital, surplus, and
undivided profits in excess of $100,000,000 (as of the date of their most
recently published financial statements). Certificates of deposit and demand and
time deposits will be those of domestic and foreign banks and savings and loan
associations, if (a) at the time of investment they have capital, surplus, and
undivided profits in excess of $100,000,000 (as of the date of their most
recently published financial statements) or (b) the principal amount of the
instrument is insured in full by the Federal Deposit Insurance Corporation.

         COLLATERALIZED MORTGAGE OBLIGATIONS. The Investment Grade Bond Fund may
invest up to 100% of its total assets and the Global Asset Allocation Fund and
the Equity Fund may each invest up to 35% of their total assets in
collateralized mortgage obligations ("CMOs"). CMOs are mortgage-related
securities which are structured pools of mortgage pass-through certificates or
mortgage loans. CMOs are issued with a number of classes or series which have
different maturities and which may represent interests in some or all of the
interest or principal on the underlying collateral or a combination thereof.
CMOs of different classes are generally retired in sequence as the underlying
mortgage loans in the mortgage pool are repaid. In the event of sufficient early
prepayments on such mortgages, the class or series of CMOs first to mature
generally will be retired prior to its maturity. Thus, the early retirement of a
particular class or series of a CMO held by a Fund would have the same effect as
the prepayment of mortgages underlying a mortgage-backed pass-through security.

         Certain debt securities such as, but not limited to, mortgage-backed
securities, CMOs and asset-backed securities, as well as securities subject to
prepayment of principal prior to the stated maturity date, are expected to be
repaid prior to their stated maturity dates. As a result, the effective maturity
of these securities is expected to be shorter than the stated maturity. For


                                      B-3
<PAGE>   59

purposes of calculating a Fund's weighted average portfolio maturity, the
effective maturity of such securities will be used.

         CMOs include stripped mortgage securities, which are derivative
multi-class mortgage securities issued by agencies or instrumentalities of the
U.S. government, or by private originators of, or investors in, mortgage loans,
including savings and loan associations, mortgage banks, commercial banks,
investment banks and special purpose subsidiaries of the foregoing. Stripped
mortgage securities are usually structured with two classes that receive
different proportions of the interest and principal distributions on a pool of
mortgage assets. A common type of stripped mortgage security will have one class
receiving all of the interest from the mortgage assets (the interest-only or
"IO" class), while the other class will receive all of the principal (the
principal-only or "PO" class). The yield to maturity on an IO class is extremely
sensitive to the rate of principal payments (including prepayments) on the
related underlying mortgage assets, and a rapid rate of principal payments may
have a material adverse effect on the securities' yield to maturity. Generally,
the market value of the PO class is unusually volatile in response to changes in
interest rates. If the underlying mortgage assets experience greater than
anticipated prepayments of principal, the Fund may fail to fully recoup its
initial investment in these securities even if the security is rated in the
highest rating category.

         Although stripped mortgage securities are purchased and sold by
institutional investors through several investment banking firms acting as
brokers or dealers, these securities were only recently developed. As a result,
established trading markets have not fully developed. Stripped mortgage
securities issued or guaranteed by the U.S. government and held by a Fund may be
considered liquid securities pursuant to guidelines established by the Board of
Trustees.

         CONVERTIBLE SECURITIES. Each Variable NAV Fund may invest up to 100% of
its total assets in convertible securities.

         COMMERCIAL PAPER. Each Fund, except for the U.S. Treasury Obligations
Fund, may invest in commercial paper. The Prime Money Market Fund may invest up
to 100% of its total assets, and the Investment Grade Bond Fund, the Global
Asset Allocation Fund, and the Equity Fund may each invest up to 35% of their
total assets in commercial paper. For temporary defensive purposes, the
Investment Grade Bond Fund, the Global Asset Allocation Fund, and the Equity
Fund may each invest up to 100% of their total assets in commercial paper.
Commercial paper consists of unsecured promissory notes issued by corporations.
Commercial paper usually has a maturity of less than nine months and has a fixed
rates of return.

         The Prime Money Market Fund, the Investment Grade Bond Fund, the Global
Asset Allocation Fund, and the Equity Fund may purchase commercial paper
designated as "Section 4(2) paper," a term that includes debt obligations issued
in reliance on the "private placement"


                                      B-4
<PAGE>   60

exemption from registration afforded by Section 4(2) of the Securities Act of
1933. Section 4(2) paper is restricted as to disposition under the Federal
securities laws, and is frequently sold (and resold) to institutional investors
through or with the assistance of investment dealers who make a market in the
Section 4(2) paper. Certain transactions in Section 4(2) paper may qualify for
the registration exemption provided in Rule 144A under the Securities Act of
1933.

         COMMON AND PREFERRED STOCK. The Investment Grade Bond Fund may invest
up to 30% of its total assets in preferred stock. The Global Asset Allocation
Fund may invest up to 75% of its assets in common and/or preferred stock. The
Equity Fund may invest up to 100% of its total assets in common and/or preferred
stock. Stocks represent shares of ownership in a company. Generally, preferred
stock has a specified dividend and ranks after bonds and before common stocks in
its claim on income for dividend payments and on assets should the company be
liquidated. After other claims are satisfied, common stockholders participate in
company profits on a pro rata basis; profits may be paid out in dividends or
reinvested in the company to help it grow. Increases and decreases in earnings
are usually reflected in a company's stock price, so common stocks generally
have the greatest appreciation and depreciation potential of all corporate
securities. While most preferred stocks pay a dividend, the Funds may purchase
preferred stock where the issuer has omitted, or is in danger of omitting,
payment of its dividend. Such investments would be made primarily for their
capital appreciation potential.

         CORPORATE BONDS. The Prime Money Market Fund, the Investment Grade Bond
Fund, and the Global Asset Allocation Fund may each invest up to 100% of their
total assets and the Equity Fund may invest up to 35% of its total assets in
corporate bonds.

         DOLLAR ROLLS. Each Variable NAV Fund may invest up to 100% of its total
assets in dollar rolls.

         FOREIGN CURRENCY TRANSACTIONS. The Global Asset Allocation Fund may use
forward foreign currency exchange contracts. Forward foreign currency exchange
contracts involve an obligation to purchase or sell a specified currency at a
future date at a price set at the time of the contract. Forward currency
contracts do not eliminate fluctuations in the values of portfolio securities
but instead allow a Fund to establish a rate of exchange for a future point in
time. The Fund may use forward foreign currency exchange contracts to hedge
against movements in the value of foreign currencies (including the "ECU" used
in the European Community) relative to the U.S. dollar in connection with
specific portfolio transactions or with respect to portfolio positions. The Fund
may enter into forward foreign currency exchange contracts when deemed advisable
by SBCL under two circumstances. First, when entering into a contract for the
purchase or sale of a security, the Fund may enter into a forward foreign
currency exchange contract for the amount of the purchase or sale price to
protect against variations, between the date the security is purchased or sold
and the date on which payment is made or received, in the value of the foreign
currency relative to the U.S.

                                      B-5
<PAGE>   61

dollar or other foreign currency.

         Second, when SBCL anticipates that a particular foreign currency may
decline relative to the U.S. dollar or other leading currencies, in order to
reduce risk, the Fund may enter into a forward contract to sell, for a fixed
amount, the amount of foreign currency approximating the value of some or all of
the Fund's securities denominated in such foreign currency. With respect to any
forward foreign currency contract, it will not generally be possible to match
precisely the amount covered by the contract and the value of the securities
involved due to the changes in the values of such securities resulting from
market movements between the date the forward contract is entered into and the
date it matures. In addition, while forward contracts may offer protection from
losses resulting from declines in the value of a particular foreign currency,
they also limit potential gains which might result from increases in the value
of such currency. The Fund will also incur costs in connection with forward
foreign currency exchange contracts and conversions of foreign currencies and
U.S. dollars.

         A separate account of a Fund consisting of liquid assets equal to the
amount of the Fund's assets that could be required to consummate forward
contracts entered into under the second circumstance, as set forth above, will
be established with the Fund's custodian. For the purpose of determining the
adequacy of the securities in the account, the deposited securities will be
valued at market or fair value. If the market or fair value of such securities
declines, additional cash or securities will be placed in the account daily so
that the value of the account will be equal the amount of such commitments by
the Fund.

         The Global Asset Allocation Fund may take positions in forward foreign
currency exchange contracts up to a value not in excess of 50% of its total
assets.

         FOREIGN INVESTMENT. The Funds, other than the U.S. Treasury Obligations
Fund, may each invest up to 35% of their total assets, and the Global Asset
Allocation Fund may invest 100% of its total assets, in certain obligations or
securities of foreign issuers. Permissible investments include Eurodollar
Certificates of Deposit ("ECDs") which are U.S. dollar denominated certificates
of deposit issued by branches of foreign and domestic banks located outside the
United States, Yankee Certificates of Deposit ("Yankee CDs") which are
certificates of deposit issued by a U.S. branch of a foreign bank, denominated
in U.S. dollars and held in the United States, Eurodollar Time Deposits
("ETD's") which are U.S. dollar denominated deposits in a foreign branch of a
U.S. bank or a foreign bank, and Canadian Time Deposits ("CTD's") which are U.S.
dollar denominated certificates of deposit issued by Canadian offices of major
Canadian banks, Canadian commercial paper, which is commercial paper issued by a
Canadian corporation or a Canadian counterpart of a U.S. corporation, and
European commercial paper, which is U.S. dollar denominated commercial paper of
an issuer located in Europe. The Funds may invest in foreign commercial paper,
including Canadian and European commercial paper as described above.


                                      B-6
<PAGE>   62

         The Investment Grade Bond Fund and the Equity Fund may each invest up
to 35% of their total assets and the Global Asset Allocation Fund may invest up
to 100% of its assets in foreign equity securities, including American
Depository Receipts (sponsored and unsponsored) ("ADRs"), European Depository
Receipts ("EDRs") and Global Depository Receipts ("GDRs").

         Each Variable NAV Fund may invest up to 15% of it total assets in
emerging market securities.

         Investments in securities issued by foreign branches of U.S. banks,
foreign banks, or other foreign issuers, including ADRs and securities purchased
on foreign securities exchanges, may subject a Fund to additional investment
risks. Such risks include adverse political and economic developments, possible
seizure, currency blockage, nationalization or expropriation of foreign
investments, less stringent disclosure requirements, exchange control
regulations, non-U.S. withholding taxes and the adoption of other foreign
governmental restrictions.

         Additional risks include currency exchange risks, less publicly
available information, the risk that companies may not be subject to the
accounting, auditing and financial reporting standards and requirements of U.S.
companies, the risk that foreign securities markets may have less volume and
therefore may be less liquid and their prices more volatile than U.S.
securities, and the risk that custodian and brokerage costs may be higher.
Foreign issuers of securities or obligations are often subject to accounting
treatment and engage in business practices different from those respecting
domestic issuers of similar securities or obligations. Foreign branches of U.S.
banks and foreign banks may be subject to less stringent reserve requirements
than those applicable to domestic branches of U.S. banks. The Funds will acquire
such securities only when SBCL believes the risks associated with such
investments are minimal.


         FUTURES CONTRACTS AND RELATED OPTIONS. The Investment Grade Bond Fund,
the Global Asset Allocation Fund, and the Equity Fund may invest in futures
contracts and options thereon (interest rate futures contracts or index futures
contracts, as applicable). Positions in futures contracts may be closed out only
on an exchange which provides a secondary market for such futures. However,
there can be no assurance that a liquid secondary market will exist for any
particular futures contract at any specific time. Thus, it may not be possible
to close a futures position. In the event of adverse price movements, a Fund
would continue to be required to make daily cash payments to maintain its
required margin. In such situations, if a Fund has insufficient cash, it may
have to sell portfolio securities to meet daily margin requirements at a time
when it may be disadvantageous to do so. In addition, a Fund may be required to
make delivery of the instruments underlying futures contracts it holds. The
inability to close options and futures positions also could have an adverse
impact on a Fund's


                                      B-7
<PAGE>   63

ability to effectively hedge.

         Successful use of futures by the Funds is also subject to SBCL's
ability to correctly predict the direction the market will move. For example, if
a Fund has hedged against the possibility of a decline in the market adversely
affecting securities held by it and securities prices increase instead, a Fund
will lose part or all of the benefit to the increased value of its securities
which it has hedged because it will have approximately equal offsetting losses
in its futures positions. In addition, in some situations, if a Fund has
insufficient cash, it may have to sell securities to meet daily variation margin
requirements. Such sales of securities 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.

         The risk of loss in trading futures contracts in some strategies can be
substantial, due both to the low margin deposits required, and the extremely
high degree of leverage involved in futures pricing. As a result, a relatively
small price movement in a futures contract may result in immediate and
substantial loss (as well as gain) to the investor. For example, if at the time
of purchase, 10% of the value of the futures contract is deposited as margin, a
subsequent 10% decrease in the value of the futures contract would result in a
total loss of the margin deposit, before any deduction for the transaction
costs, if the account were then closed out. A 15% decrease would result in a
loss equal to 150% of the original margin deposit, before any deduction for the
transaction costs, if the contract were closed out. Thus, a purchase or sale of
a futures contract may result in losses in excess of the amount invested in the
contract.

         Utilization of futures transactions by a Fund involves the risk of loss
by a Fund of margin deposits in the event of bankruptcy of a broker with whom a
Fund has an open position in a futures contract or related option.

         Most futures exchanges limit the amount of fluctuation permitted in
futures contract prices during a single trading day. The daily limit establishes
the maximum amount that the price of a futures contract may vary either up or
down from the previous day's settlement price at the end of a trading session.
Once the daily limit has been reached in a particular type of contract, no
trades may be made on that day at a price beyond that limit. The daily limit
governs only price movement, during a particular trading day and therefore does
not limit potential losses, because the limit may prevent the liquidation of
unfavorable positions. Futures contract prices have occasionally moved to the
daily limit for several consecutive trading days with little or no trading,
thereby preventing prompt liquidation of futures positions and subjecting some
futures traders to substantial losses.

         The trading of futures contracts is also subject to the risk of trading
halts, suspensions, exchange or clearing house equipment failures, government
intervention, insolvency of a brokerage firm or clearing house or other
disruptions of normal trading activity, which could at times make it difficult
to impossible to liquidate existing positions or to recover excess


                                      B-8
<PAGE>   64

variation margin payments.

         GUARANTEED INVESTMENT CONTRACTS. Guaranteed investment contracts
("GICs") are issued by highly rated U.S. insurance companies. Under these
contracts, a Fund makes cash contributions to a deposit fund of the insurance
company's general account. The insurance company then credits interest to the
Fund on a monthly basis, which is based on an index (such as the Solomon
Brothers CD Index), but is guaranteed not to be less than a certain minimum
rate.

         ILLIQUID AND RESTRICTED SECURITIES. The Prime Money Market may invest
up to 10% of its net assets in illiquid securities. The Investment Grade Bond
Fund, Global Asset Allocation Fund, and the Equity Fund may invest up to 15% of
their net assets in illiquid securities. Each Fund, except the U.S. Treasury
Obligations Fund, may invest in restricted securities. Some investments may be
determined by SBCL, under the supervision of the Board of Trustees, to be
illiquid. Securities may be deemed illiquid if the Fund cannot reasonably expect
within seven days to sell the securities for approximately the amount at which
the Fund values such securities. The sale of illiquid securities, if they can be
sold at all, generally will require more time and result in higher brokerage
charges or dealer discounts and other selling expenses than will the sale of
liquid securities such as securities eligible for trading on U.S. securities
exchanges or in over-the-counter markets. Moreover, restricted securities, which
may be illiquid, often sell, if at all, at a price lower than similar securities
that are not subject to restrictions on resale.

         Illiquid securities include those that are subject to restrictions
contained in the securities laws of other countries. However, securities that
are freely marketable in the country where they are principally traded, but
would not be freely marketable in the United States, will not be considered
illiquid. Where registration is required, the Fund may be obligated to pay all
or part of the registration expenses and a considerable period may elapse
between the time of the decision to sell and the time the Fund may be permitted
to sell a security under an effective registration statement. If, during such a
period, adverse market conditions were to develop, the Fund might obtain a less
favorable price than prevailed when it decided to sell.

         Not all restricted securities are illiquid. In recent years a large
institutional market has developed for certain securities that are not
registered under the Securities Act of 1933, including private placements,
repurchase agreements, commercial paper, foreign securities and corporate bonds
and notes. These instruments are often restricted securities because the
securities are sold in transactions not requiring registration. Institutional
investors generally will not seek to sell these instruments to the general
public, but instead will often depend either on an efficient institutional
market in which such unregistered securities can be readily resold or on an
issuer's ability to honor a demand for repayment. Therefore, the fact that there
are contractual or legal restrictions on resale to the general public or certain
institutions is not dispositive of the liquidity of such investments.

<PAGE>   65

         INVESTMENT COMPANY SECURITIES. Each Fund may invest up to 10% of its
total assets in money market investment company securities. The Global Asset
Allocation Fund may invest up to 10% of its total assets in non-money market
investment company securities. By investing in investment companies, a Fund
becomes exposed to the risks of that investment company's portfolio of
securities. Securities of other investment companies will be acquired by the
Funds within the limits prescribed by the 1940 Act. As a shareholder of another
investment company, a Fund would bear, along with other shareholders, its pro
rata portion of the other investment company's expenses, including advisory
fees. These expenses would be in addition to the advisory fees and other
expenses the Fund bear directly in connection with its own operations.

         INVESTMENT GRADE DEBT OBLIGATIONS. The Variable NAV Funds may invest in
"investment grade securities," which are securities rated in the four highest
rating categories of an NRSRO. It should be noted that debt obligations rated in
the lowest of the top four ratings (i.e., "Baa" by Moody's) are considered to
have some speculative characteristics and are more sensitive to economic change
than higher rated securities.

         Under normal circumstances at least 80% of the Investment Grade Bond
Fund's assets will be invested in investment grade debt securities (securities
that, at the time of initial investment, are rated equal to or greater than BBB-
by Standard & Poor's or Baa3 by Moody's). With respect to 80% of its assets, the
Fund will only invest in unrated debt securities should SBCL determine that the
security is of comparable quality to an investment grade issue. With respect to
80% of its assets, the Fund will not invest in securities that, at the time of
initial investment, do not meet the above credit guidelines. Investment grade
securities that are subsequently downgraded in quality below investment grade by
both Standard & Poor's and Moody's may continue to be held in the portfolio, and
will be sold only if SBCL believes it would be advantageous to do so. The Fund
may invest up to 20% of its assets in debt securities rated B- and above.
Securities rated less than BBB- by Standard & Poor's and Baa3 by Moody's are
classified as non-investment grade securities. Such securities carry a high
degree of risk and are considered speculative by the major credit ratings
agencies. Credit quality in the non-investment grade bond market can change
suddenly and unexpectedly and even recently issued credit rating may not fully
reflect the actual risks posed by a particular non-investment grade security.

         MUNICIPAL OBLIGATIONS. The Prime Money Market Fund and the Investment
Grade Bond Fund may each invest up to 35% of their total assets in municipal
obligations. The Prime Money Market Fund will only invest in municipal
securities rated in the top two tiers by a NRSRO. Municipal securities are debt
securities issued by a state, its political subdivisions, agencies, authorities
and corporations. Municipal securities include debt obligations issued to obtain
funds for various public purposes, including the construction of a wide range of
public facilities such as airports, bridges, highways, housing, hospitals, mass
transportation, public utilities, schools, streets, and water and sewer works.
Other public purposes for which


                                      B-10
<PAGE>   66

municipal securities may be issued include refunding outstanding obligations,
obtaining funds for general operating expenses and obtaining funds to loan to
other public institutions and facilities.

         Municipal securities include securities issued to finance various
private activities, including certain types of private activity bonds
("industrial development bonds" under prior law). These securities may be issued
by or on behalf of public authorities to obtain funds to provide certain
privately owned or operated facilities.

         Municipal securities are generally classified as "general obligation"
or "revenue." General obligation securities are secured by the issuer's pledge
of its full credit and taxing power for the payment of principal and interest.
Revenue securities are payable only from the revenues derived from a particular
facility or class of facilities or, in some cases, from the proceeds of a
special excise or other specific revenue source. Private activity bonds and
industrial development bonds that are municipal securities are in most cases
revenue bonds and generally do not constitute the pledge of the credit of the
issuer of such bonds.

         Municipal notes are instruments issued by or on behalf of governments
and political sub-divisions thereof. Examples include: tax anticipation notes,
which are short-term debt instruments issued by a municipality or state to
finance working capital needs of the issuer in anticipation of receiving taxes
on a future date; revenue anticipation notes, which are short-term debt
instruments issued by a municipality or state to provide cash prior to receipt
of expected non-tax revenues from a specific source; bond anticipation notes,
which are short-term debt instruments issued by a municipality or state that
will be paid off with the proceeds of an upcoming bond issue; and tax revenue
anticipation notes, which are short-term debt instruments issued by a
municipality or state to finance working capital needs in anticipation of
receiving taxes or other revenues. Construction loan notes are instruments
insured by the Federal Housing Administration with permanent financing by
"Fannie Mae" (the Federal National Mortgage Association) or "Ginnie Mae" (the
Government National Mortgage Association) at the end of the project construction
period. Tax-free commercial paper is an unsecured promissory obligation issued
or guaranteed by a municipal issuer.

         Taxable municipal securities are municipal securities the interest on
which is not exempt from federal income tax. Taxable municipal securities may
include "private activity bonds" that are issued by or on behalf of states or
political subdivisions thereof to finance privately-owned or operated facilities
for business and manufacturing, housing, sports, and pollution control and to
finance facilities for charitable institutions. The payment of the principal and
interest on private activity bonds is not backed by a pledge of tax revenues,
and is dependent solely on the ability of the facility's user to meet its
financial obligations. Taxable municipal securities also may include remarketed
certificates of participation.

         The federal bankruptcy statutes relating to the adjustments of debts of
political


                                      B-11
<PAGE>   67

subdivisions and authorities of states of the United States provide that, in
certain circumstances, such subdivisions or authorities may be authorized to
initiate bankruptcy proceedings without prior notice to or consent of creditors,
which proceedings could result in material adverse changes in the rights of
holders of obligations issued by such subdivisions or authorities.

         Municipal securities also include participation certificates in a
lease, an installment purchase contract, or a conditional sales contract ("lease
obligations") entered into by a state or political subdivision to finance the
acquisition or construction of equipment, land or facilities. Although lease
obligations are not general obligations of the issuer for which the state or
other governmental body's unlimited taxing power is pledged, certain lease
obligations are backed by a covenant to appropriate money to make the lease
obligation payments. However, under certain lease obligations, the state or
governmental body has no obligation to make these payments in future years
unless money is appropriated on a yearly basis. Although "non-appropriation"
lease obligations are secured by the leased property, disposition of the
property in the event of foreclosure might prove difficult. These securities
represent a relatively new type of financing that is not yet marketable as more
conventional securities. Certain investments in lease obligations may be
illiquid. Under guidelines established by the Board of Trustees, the following
factors will be considered when determining the liquidity of a lease obligation:
(1) the frequency of trades and quotes for the obligation; (2) the number of
dealers willing to purchase or sell the obligation and the number of potential
buyers; (3) the willingness of dealers to undertake to make a market in the
obligation; and (4) the nature of the marketplace trades.

         OPTIONS - CALLS AND PUTS.

         Calls. The Variable NAV Funds may write (sell) "covered" call options
and purchase options to close out options previously written by it. Such options
must be listed on a National Securities Exchange and issued by the Options
Clearing Corporation. The purpose of writing covered call options is to generate
additional income. This premium income will serve to enhance each Fund's total
return and will reduce the effect of any price decline of the security involved
in the option.

         A call option gives the holder (buyer) the "right to purchase" a
security at a specified price (the exercise price) at any time until a certain
date (the expiration date). So long as the obligation of the writer of a call
option continues, the writer may be assigned an exercise notice by the
broker-dealer through whom such option was sold, requiring the writer to deliver
the underlying security against payment of the exercise price. This obligation
terminates upon the expiration of the call option, or such earlier time at which
the writer effects a closing purchase transaction by repurchasing an option
identical to that previously sold. To secure the writer's obligation to deliver
the underlying security in the case of a call option, a writer is required to
deposit in escrow the underlying security or other assets in accordance with the


                                      B-12
<PAGE>   68

rules of the Options Clearing Corporation. The Funds will write only covered
call options. This means that a Fund will only write a call option on a security
which it already owns.

         The Variable NAV Funds will write call options only if they are
"covered" and may buy call options. In the case of a call option on a security,
the option is "covered" if the Fund owns the security underlying the call or has
an absolute and immediate right to acquire that security without additional cash
consideration (or, if additional cash consideration is required, cash or cash
equivalents in such amount as are held in a segregated account by its custodian)
upon conversion or exchange of other securities held by it. For a call option on
an index, the option is covered if the Fund maintains with its custodian cash or
cash equivalents equal to the contract value. A call option is also covered if
the Fund holds a call on the same security or index as the call written where
the exercise price of the call held is (i) equal to or less than the exercise
price of the call written, or (ii) greater than the exercise price of the call
written provided the difference is maintained by the Fund in cash or cash
equivalents in a segregated account with its custodian.

         Fund securities on which call options may be written will be purchased
solely on the basis of investment considerations consistent with a Fund's
investment objectives. The writing of covered call options is a conservative
investment technique believed to involve relatively little risk (in contrast to
the writing of naked or uncovered options which the Funds will not do), but
capable of enhancing a Fund's total return. When writing a covered call option,
a Fund, in return for the premium, gives up the opportunity for profit from a
price increase in the underlying security above the exercise price, but retains
the risk of loss should the price of the security decline. Unlike owning
securities not subject to an option, a Fund does not have any control over the
point at which it may be required to sell the underlying securities, because it
may be assigned an exercise notice at any time prior to the expiration of its
obligation as a writer. If a call option which a Fund has written expires, the
Fund will realize a gain in the amount of the premium; however, such gain may be
offset by a decline in the market value of the underlying security during the
option period. If the call option is exercised, a Fund will realize a gain or
loss from the sale of the underlying security. The security covering the call
will be maintained in a segregated account by the Fund's custodian. A Fund does
not consider a security covered by a call to be "pledged" as that term is used
in its policy which limits the pledging or mortgaging of its assets.

         The premium received is the market value of an option. The premium a
Fund will receive from writing a call option will reflect, among other things,
the current market price of the underlying security, the relationship of the
exercise price to such market price, the historical price volatility of the
underlying security, and the length of the option period. Once the decision to
write a call option has been made, SBCL, in determining whether a particular
call option should be written on a particular security, will consider the
reasonableness of the anticipated premium and the likelihood that a liquid
secondary market will exist for the option. The premium received by a Fund for
writing covered call options will be recorded as a


                                      B-13
<PAGE>   69

liability in a Fund's statement of assets and liabilities. This liability will
be readjusted daily to the option's current market value, which will be the
latest sale price at the time at which the net asset value per share of a Fund
is computed (close of the New York Stock Exchange (the "NYSE")), or, in the
absence of such sale, the latest asked price (or, with respect to the Global
Asset Allocation Fund, the mean between the last bid and asked prices). The
liability will be extinguished upon expiration of the option, the purchase of an
identical option in the closing transaction, or delivery of the underlying
security upon the exercise of the option.

         Closing transactions will be effected in order to realize a profit on
an outstanding call option, to prevent an underlying security from being called,
or to permit the sale of the underlying security. Furthermore, effecting a
closing transaction will permit a Fund to write another call option on the
underlying security with either a different exercise price or expiration date or
both. If a Fund desires to sell a particular security from its portfolio on
which it has written a call option, it will seek to effect a closing transaction
prior to, or concurrently with, the sale of the security. There is, of course,
no assurance that a Fund will be able to effect such closing transactions at a
favorable price. If a Fund cannot enter into such a transaction, it may be
required to hold a security that it might otherwise have sold, in which case it
would continue to be at market risk on the security. This could result in higher
transaction costs. A Fund will pay transaction costs in connection with the
writing of options to close out previously written options. Such transaction
costs are normally higher than those applicable to purchases and sales of
portfolio securities.

         Call options written by a Fund will normally have expiration dates of
less than nine months from the date written. The exercise price of the options
may be below, equal to, or above the current market values of the underlying
securities at the time the options are written. From time to time, a Fund may
purchase an underlying security for delivery in accordance with an exercise
notice of a call option assigned to it, rather than delivering such security
from its portfolio. In such cases, additional costs will be incurred.

         A Fund will realize a profit or loss from a closing purchase
transaction if the cost of the transaction is less or more than the premium
received from the writing of the option. Because increases in the market price
of a call option will generally reflect increases in the market price of the
underlying security, any loss resulting from the repurchase of a call option is
likely to be offset in whole or in part by appreciation of the underlying
security owned by a Fund.

         Puts. A put is a right to sell a specified security (or securities)
within a specified period of time at a specified exercise price. To the extent
consistent with its investment objective, the Variable NAV Funds may buy put
options and write secured put options.

         The amount payable to a Fund upon its exercise of a "put" is normally
(i) the Fund's acquisition cost of the securities subject to the put (excluding
any accrued interest which the Fund paid on the acquisition), less any amortized



                                      B-14
<PAGE>   70

market premium or plus any amortized market or original issue discount during
the period the Fund owned the securities, plus (ii) all interest accrued on the
securities since the last interest payment date during that period.

         These options may relate to particular securities, financial
instruments, foreign currencies, stock or bond indices or the yield differential
between two securities, and may or may not be listed on a securities exchange
and may or may not be issued by the Options Clearing Corporation. Options
trading is a highly specialized activity that entails greater than ordinary
investment risks. In addition, unlisted options are not subject to the
protections afforded purchasers of listed options issued by the Options Clearing
Corporation, which performs the obligations of its members if they default.
Cross hedging is the use of options or forward contracts in one currency to
hedge against fluctuations in the value of securities denominated in a different
currency based on a belief that there is a pattern of correlation between the
two currencies. The Funds intend to enter into puts only with dealers, banks,
and broker-dealers which, in SBCL's opinion, present minimal credit risks.

         Risk Factors Relating to Options. There are several risks associated
with transactions in put and call options. For example, there are significant
differences between the securities and options markets that could result in an
imperfect correlation between these markets, causing a given transaction not to
achieve its objectives. In addition, a liquid secondary market for particular
options, whether traded over-the-counter or on a national securities exchange
("Exchange") may be absent for reasons which include the following: there may be
insufficient trading interest in certain options, restrictions may be imposed by
an Exchange on opening transactions or closing transactions or both; trading
halts, suspensions or other restrictions may be imposed with respect to
particular classes or series of options or underlying securities; unusual or
unforeseen circumstances may interrupt normal operations on an Exchange; the
facilities of an Exchange or the Options Clearing Corporation may not at all
times be adequate to handle current trading volume; or one or more Exchanges
could, for economic or other reasons, decide or be compelled at some future date
to discontinue the trading of options (or a particular class or series of
options), in which event the secondary market on that Exchange (or in that class
or series of options) would cease to exist, although outstanding options that
had been issued by the Options Clearing Corporation as a result of trades on
that Exchange would continue to be exercisable in accordance with their terms.
In addition, the success of a hedging strategy based on options transactions may
depend on the ability of SBCL to predict movements in the prices of individual
securities, fluctuations in markets and movements in interest rates.

         REPURCHASE AGREEMENTS. Securities held by each of the Funds may be
subject to repurchase agreements. Under the terms of a repurchase agreement, a
Fund would acquire securities from member banks of the Federal Deposit Insurance
Corporation with capital, surplus, and undivided profits of not less than
$100,000,000 (as of the date of their most recently published financial
statements) and from registered broker-dealers which SBCL deems creditworthy
under guidelines approved by the Board of Trustees, subject to the seller's


                                      B-15
<PAGE>   71

agreement to repurchase such securities at a mutually agreed-upon date and
price. The repurchase price would generally equal the price paid by the Fund
plus interest negotiated on the basis of current short-term rates, which may be
more or less than the rate on the underlying portfolio securities. The seller
under a repurchase agreement will be required to maintain the value of
collateral held pursuant to the agreement at not less than the repurchase price
(including accrued interest) and SBCL will monitor the collateral's value to
ensure that it equals or exceeds the repurchase price (including accrued
interest). In addition, securities subject to repurchase agreements will be held
in a segregated account.

         If the seller were to default on its repurchase obligation or become
insolvent, a Fund holding such obligation would suffer a loss to the extent that
the proceeds from a sale of the underlying portfolio securities were less than
the repurchase price under the agreement, or to the extent that the disposition
of such securities held by the Fund were delayed pending court action.
Additionally, if the seller should be involved in bankruptcy or insolvency
proceedings, a Fund may incur delay and costs in selling the underlying security
or may suffer a loss of principal and interest if the Fund is treated as an
unsecured creditor and required to return the underlying security to the
seller's estate. Securities subject to repurchase agreements will be held by the
Eureka Funds' custodian or another qualified custodian or in the Federal
Reserve/Treasury book-entry system. Repurchase agreements are considered to be
loans by a Fund under the Investment Company Act of 1940 (the "1940 Act").

         REVERSE REPURCHASE AGREEMENTS. Each Fund may borrow funds for temporary
purposes by entering into reverse repurchase agreements in accordance with each
Fund's investment restrictions. Each Fund may borrow up to 33 1/3% of its total
assets. Pursuant to such agreements, a Fund would sell portfolio securities to
financial institutions such as banks and broker-dealers, and agree to repurchase
the securities at a mutually agreed-upon date and price. Each Fund intends to
enter into reverse repurchase agreements only to avoid otherwise selling
securities during unfavorable market conditions to meet redemptions. At the time
a Fund enters into a reverse repurchase agreement, it will place in a segregated
custodial account liquid assets consistent with the Fund's investment
restrictions having a value equal to the repurchase price (including accrued
interest), and will subsequently monitor the account to ensure that such
equivalent value is maintained. Such assets will include U.S. government
securities or other liquid high quality debt securities or high grade debt
securities. Reverse repurchase agreements involve the risk that the market value
of the securities sold by a Fund may decline below the price at which it is
obligated to repurchase the securities. Reverse repurchase agreements are
considered to be borrowings by a Fund under the 1940 Act.

         RIGHTS OFFERINGS AND WARRANTS TO PURCHASE. The Variable NAV Funds may
participate in rights offerings and may purchase warrants, which are privileges
issued by corporations enabling the owners to subscribe to and purchase a
specified number of shares of the corporation at a specified price during a
specified period of time. Subscription rights normally have a short life span to
expiration. The purchase of rights or warrants involves the risk that


                                      B-16
<PAGE>   72

the Fund could lose the purchase value of a right or warrant if the right to
subscribe to additional shares is not exercised prior to the rights' and
warrants' expiration. Also, the purchase of rights and/or warrants involves the
risk that the effective price paid for the right and/or warrant added to the
subscription price of the related security may exceed the value of the
subscribed security's market price such as when there is no movement in the
level of the underlying security. A Fund will not invest more than 5% of its net
assets, taken at market value, in warrants, or more than 2% of its net assets,
taken at market value, in warrants not listed on the New York or American Stock
Exchanges. Warrants acquired by a Fund in units or attached to other securities
are not subject to this restriction.

         SECURITIES LENDING. Each Fund may engage in securities lending.
Securities lending is limited to 33 1/3% of a Fund's total assets. While the
lending of securities may subject a Fund to certain risks, such as delays or the
inability to regain the securities in the event the borrower was to default on
its lending agreement or enter into bankruptcy, the Fund will receive 100%
collateral in the form of cash or U.S. government securities. This collateral
will be valued daily by SBCL and should the market value of the loaned
securities increase, the borrower will furnish additional collateral to the
Fund. During the time portfolio securities are on loan, the borrower will pay
the Fund any dividends or interest paid on such securities. Loans are subject to
termination by a Fund or the borrower at any time. While a Fund will not have
the right to vote securities on loan, the Funds intend to terminate the loan and
regain the right to vote if that is considered important with respect to the
investment. The Funds will only enter into loan arrangements with
broker-dealers, banks or other institutions which SBCL has determined are
creditworthy under guidelines established by the Board of Trustees.

         SHORT-TERM TRADING. Each Variable NAV Fund may engage in short-term
trading. Short-term trading involves the selling of securities held for a short
time, ranging from several months to less than a day. The object of such
short-term trading is to increase the potential for capital appreciation and/or
income of the Funds in order to take advantage of what SBCL believes are changes
in market, industry or individual company conditions or outlook. Any such
trading would increase the portfolio turnover rate of the Funds and their
transaction costs. In addition, short-term trading may increase the amount of
taxes payable by shareholders.

         SUPRANATIONAL ORGANIZATIONAL OBLIGATIONS. The Funds, other than the
U.S. Treasury Obligations Fund, may purchase debt securities of supranational
organizations such as the European Coal and Steel Community, the European
Economic Community and the World Bank, which are chartered to promote economic
development.

         SWAPS. Each Variable NAV Fund may enter swap agreements. Swap
agreements (a common form of derivatives) are contracts between parties in which
one party agrees to make payments to the other party based on the change in
market value of a specified index or asset. In return, the other party agrees to
make payments to the first party based on the return of a different specified
index or asset. Although swap agreements entail the risk that a party will


                                      B-17
<PAGE>   73

default on its payment obligations the Funds will minimize this risk by entering
into agreements that mark to market no less frequently than quarterly. Swap
agreements also bear the risk that the Funds will not be able to meet their
obligations to the counterparty. This risk will be mitigated by having the Funds
invest in an equivalent asset for which they are obligated to pay a return. Swap
agreements may be considered illiquid and therefore subject to a Fund's
limitation on illiquid securities.

         U.S. GOVERNMENT OBLIGATIONS. The U.S. Treasury Obligations Fund will
invest exclusively in bills, notes and bonds issued or guaranteed by the U.S.
Treasury or agency obligations which are also supported by the full faith and
credit of the U.S. government. Each of the other Funds may invest in such
obligations and in other obligations issued or guaranteed by the U.S.
government, its agencies and instrumentalities. Such other obligations may
include those which are supported by the full faith and credit of the U.S.
government; others which are supported by the right of the issuer to borrow from
the Treasury; others which are supported by the discretionary authority of the
U.S. government to purchase the agency's obligations; and still others which are
supported only by the credit of the instrumentality. No assurance can be given
that the U.S. government would provide financial support to U.S.
government-sponsored agencies and instrumentalities if it is not obligated to do
so by law. A Fund will invest in the obligations of such agencies and
instrumentalities only when SBCL believes that the credit risk with respect
thereto is minimal.

         U.S. GOVERNMENT AGENCY SECURITIES. The Prime Money Market Fund, the
U.S. Treasury Obligations Fund, the Investment Grade Bond Fund, and the Global
Asset Allocation Fund may each invest 100% of their total assets in U.S.
government agency securities. The Equity Fund may invest up to 35% of its total
assets in U.S. government agency securities and for temporary defensive purposes
may invest 100% of its total assets in U.S. government agency securities. U.S.
government agency securities include obligations issued or guaranteed as to
payment of principal and interest by the full faith and credit of the U.S.
government, such as Treasury bills, notes, bonds and certificates of
indebtedness, and obligations issued or guaranteed by the agencies or
instrumentalities of the U.S. government, but not supported by such full faith
and credit. Obligations of certain agencies and instrumentalities of the U.S.
government, such as GNMA and the Export-Import Bank of the United States, are
supported by the full faith and credit of the U.S. Treasury; others, such as
those of FNMA, are supported by the right of the issuer to borrow from the
Treasury; others are supported by the discretionary authority of the U.S.
government to purchase the agency's obligations; still others, such as those of
the Federal Farm Credit Banks, or the Federal Home Loan Mortgage Corporation,
are supported only by the credit of the instrumentality. No assurance can be
given that the U.S. government would provide financial support to U.S.
government-sponsored agencies or instrumentalities if it is not obligated to do
so by law.

         U.S. government agency securities may include mortgage-backed
pass-through securities. Interest and principal payments (including prepayments)
on the mortgages


                                      B-18
<PAGE>   74

underlying such securities are passed through to the holders of the security.
Prepayments occur when the borrower under an individual mortgage repays the
remaining principal before the mortgage's scheduled maturity date. As a result
of the pass-through of prepayments of principal on the underlying securities,
mortgage-backed pass-through securities are often subject to more rapid
prepayments of principal than their stated maturity would indicate. Because the
prepayment characteristics of the underlying mortgages vary, it is not possible
to predict accurately the realized yield or average life of a particular issue
of pass-through certificates. Prepayments are important because of their effect
on the yield and price of the securities. During periods of declining interest
rates, such prepayments can be expected to accelerate, and the Funds would be
required to reinvest the proceeds at the lower interest rates then available. In
addition, prepayments of mortgages which underlie securities purchased at a
premium may not have been fully amortized at the time the obligation is repaid.
As a result of these principal prepayment features, mortgage-backed pass-through
securities are generally more volatile investments than other U.S. government
agency securities.

         "Zero coupon" U.S. government agency securities also tend to be more
volatile than other types of U.S. government agency securities. Zero coupon
securities are debt instruments that do not pay current interest and are
typically sold at prices greatly discounted from par value. The return on a zero
coupon obligation, when held to maturity, equals the difference between the par
value and the original purchase price.

         U.S. TREASURY SECURITIES. The Prime Money Market Fund, the U.S.
Treasury Obligations Fund, the Investment Grade Bond Fund, and the Global Asset
Allocation Fund may each invest up to 100% of their total assets in U.S.
Treasury securities. The Equity Fund may invest up to 35% of its total assets in
U.S. Treasury securities and for temporary defensive purposes may invest up to
100% of its total assets in U.S. Treasury securities.

         VARIABLE AMOUNT MASTER DEMAND NOTES. Variable amount master demand
notes, in which the Funds, except for the U.S. Treasury Obligations Fund, may
invest are unsecured demand notes that permit the indebtedness thereunder to
vary and provide for periodic adjustments in the interest rate according to the
terms of the instrument. They are also referred to as variable rate demand
notes. Because these notes are direct lending arrangements between the Fund and
the issuer, they are not normally traded. Although there may be no secondary
market in the notes, the Fund may demand payment of principal and accrued
interest at any time or during specified periods not exceeding one year,
depending upon the instrument involved, and may resell the note at any time to a
third party. The absence of such an active secondary market, however, could make
it difficult for a Fund to dispose of a variable amount master demand note if
the issuer defaulted on its payment obligations or during periods when the Fund
is not entitled to exercise their demand rights, and a Fund could, suffer a loss
to the extent of the default. While the notes are not typically rated by credit
rating agencies, issuers of variable amount master demand notes must satisfy the
criteria for commercial paper. SBCL will consider the earning power, cash flow,
and other liquidity ratios of the issuers of such


                                      B-19
<PAGE>   75

notes and will continuously monitor their financial status and ability to meet
payment on demand. Where necessary to ensure that a note is of "high quality," a
Fund will require that the issuer's obligation to pay the principal of the note
be backed by an unconditional bank letter or line of credit, guarantee or
commitment to lend. In determining dollar-weighted average portfolio maturity, a
variable amount master demand note will be deemed to have a maturity equal to
the period of time remaining until the principal amount can be recovered from
the issuer through demand.

         VARIABLE AND FLOATING RATE NOTES. The Funds, other than the U.S.
Treasury Obligations Fund, may acquire variable and floating rate notes, subject
to that Fund's investment objective, policies, and restrictions. A variable rate
note is one whose terms provide for the adjustment of its interest rate on set
dates and which, upon such adjustment, can reasonably be expected to have a
market value that approximates its par value. A floating rate note is one whose
terms provide for the adjustment of its interest rate whenever a specified
interest rate changes and which, at any time, can reasonably be expected to have
a market value that approximates its par value. Such notes are frequently not
rated by credit rating agencies; however, unrated variable and floating rate
notes purchased by a Fund will be determined by SBCL under guidelines
established by the Board of Trustees to be of comparable quality at the time of
purchase to rated instruments eligible for purchase under a Fund's investment
policies. In making such determinations, SBCL will consider the earning power,
cash flow and other liquidity ratios of the issuers of such notes (such issuers
include financial, merchandising, bank holding and other companies) and will
continuously monitor their financial condition. Although there may be no active
secondary market with respect to a particular variable or floating rate note
purchased by a Fund, it may resell a note at any time to a third party. The
absence of an active secondary market, however, could make it difficult for a
Fund to dispose of a variable or floating rate note in the event the issuer of
the note defaulted on its payment obligations and a Fund could, as a result or
for other reasons, suffer a loss to the extent of the default. Variable or
floating rate notes may be secured by bank letters of credit.

         For purposes of the Money Market Funds, the maturities of the variable
and floating rate notes will be determined in accordance with Rule 2a-7 under
the 1940 Act.

         WHEN-ISSUED SECURITIES. Each Fund may purchase securities on a
when-issued basis and may purchase and sell securities on a forward commitment
basis (I.E., for delivery beyond the normal settlement date at a stated price
and yield), including "TBA" (to be announced) purchase commitments. When a Fund
agrees to purchase securities on a when-issued or forward commitment basis, the
Fund's custodian will set aside cash or liquid portfolio securities equal to the
amount of the commitment in a separate account. Normally, the custodian will set
aside portfolio securities to satisfy the purchase commitment, and in such a
case, a Fund may be required subsequently to place additional assets in the
separate account in order to assure that the value of the account remains equal
to the amount of the Fund's


                                      B-20
<PAGE>   76

commitment. It may be expected that any such Fund's net assets will fluctuate to
a greater degree when it sets aside portfolio securities to cover such purchase
commitments than when it sets aside cash.

         When a Fund engages in when-issued or forward commitment transactions,
it relies on the seller to consummate the trade. Failure of the seller to do so
may result in the Fund incurring a loss or missing the opportunity to obtain a
price considered to be advantageous. In addition, the purchase of securities on
a when-issued or forward commitment basis involves a risk of loss if the value
of the security to be purchased declines prior to the settlement date. Each of
the Funds does not intend to purchase when-issued securities for speculative
purposes but only in furtherance of its investment objective.

INVESTMENT RESTRICTIONS

         For each Fund the following investment restrictions are fundamental and
cannot be changed without approval of the holders of a majority of the
outstanding voting securities (as defined in the 1940 Act) of that Fund.

         1. The Fund may lend or borrow money to the extent permitted by the
         1940 Act or the rules or regulations thereunder, as such statute, rules
         or regulations may be amended from time to time.

         2. The Fund may pledge, mortgage or hypothecate any of its assets to
         the extent permitted by the 1940 Act or the rules or regulations
         thereunder, as such statute, rules or regulations may be amended from
         time to time.

         3. The Fund may issue senior securities to the extent permitted by the
         1940 Act or the rules or regulations thereunder, as such statute, rules
         or regulations may be amended from time to time.

         4. The Fund may purchase securities of any issuer only when consistent
         with the maintenance of its status as a diversified company under the
         1940 Act or the rules or regulations thereunder, as such statute, rules
         or regulations may be amended from time to time.

         5. The Fund may not concentrate investments in a particular industry or
         group of industries as concentration is defined under the 1940 Act, or
         the rules or regulations thereunder, as such statute, rules or
         regulations may be amended from time to time.

         6. The Fund may underwrite securities to the extent permitted by the
         1940 Act or the rules or regulations thereunder, as such statute, rules
         or regulations may be amended from time to time.

                                      B-21
<PAGE>   77
         7. The Fund may purchase or sell commodities, commodities contracts,
         futures contracts, or real estate to the extent permitted by the 1940
         Act or the rules or regulations thereunder, as such statute, rules or
         regulations may be amended from time to time.

ADDITIONAL INFORMATION REGARDING FUNDAMENTAL INVESTMENT RESTRICTIONS

         The fundamental investment restrictions limit a Fund's ability to
engage in certain investment practices and purchase securities to the extent
permitted by, or consistent with, the 1940 Act. Relevant limitations of the 1940
Act are described below. Each Fund may be subject to more restrictive
non-fundamental investment policies. Non-fundamental investment policies may be
changed by the Board of Trustees.

         The following 1940 Act descriptions are to assist the investor in
understanding the fundamental restrictions above, and are not themselves
fundamental.

         FUNDAMENTAL INVESTMENT RESTRICTION (1). The 1940 Act presently limits a
Fund's ability to borrow to one-third of the value of its total assets.
Borrowing by a Fund allows it to leverage its portfolio, which exposes it to
certain risks. Leveraging exaggerates the effect of any increase or decrease in
the value of portfolio securities on a Fund's net asset value, and money
borrowed will be subject to interest costs (which may include commitment fees
and/or the cost of maintaining minimum average balances) which may or may not
exceed the interest received from the securities purchased with borrowed funds.

         The 1940 Act also restricts the ability of any mutual fund to lend.
Under the 1940 Act, a Fund may only make loans if expressly permitted to do so
by the Fund's investment policies, and a Fund may not make loans to persons who
control or are under common control with the Fund. Thus, the 1940 Act
effectively prohibits a Fund from making loans to certain persons when conflicts
of interest or undue influence are most likely present. The Funds may, however,
make other loans which if made would expose shareholders to certain additional
risks.

         FUNDAMENTAL INVESTMENT RESTRICTION (2). The 1940 Act limits a Fund's
ability to pledge, mortgage or hypothecate its assets to one-third of its
assets. To the extent that pledged assets are encumbered for more than seven
days such assets would be considered illiquid and, therefore, each Fund's use of
such techniques would be limited to 15% of its net assets (10% for the Money
Market Funds).

         FUNDAMENTAL INVESTMENT RESTRICTION (3). The ability of a mutual fund to
issue senior securities is severely circumscribed by complex regulatory
constraints under the 1940 Act that restrict, for instance, the amount, timing,
and form of senior securities that may be issued. Because portfolio management
techniques involving the issuance of senior securities, such as


                                      B-22
<PAGE>   78

the purchase of securities on margin, short sales, or the writing of puts on
portfolio securities, are all techniques that involve the leveraging of a
portfolio and would not be consistent with the current SEC rules governing Money
Market Funds.

         FUNDAMENTAL INVESTMENT RESTRICTION (4). Under Section 5(b) of the 1940
Act, an investment company is diversified if, as to 75% of its total assets, no
more than 5% of the value of its total assets is invested in the securities of a
single issuer and no more than 10% of the issuer's voting securities is held by
the investment company. However, each of the Funds is subject to the "per
issuer" diversification requirements of the Internal Revenue Code of 1986
("Code") at the Fund's tax quarter-ends. Under the Code, the 5% "per issuer"
limit is applied only to 50% of a Fund's total assets (not 75% of total assets
as under the 1940 Act). However, no single issuer can exceed 25% of a Fund's
total assets under the Code as well as under the 1940 Act.

         FUNDAMENTAL INVESTMENT RESTRICTION (5). "Concentration" is interpreted
under the 1940 Act to mean investment of 25% or more of a Fund's total assets in
a single industry. If a Fund were to "concentrate" its investments in a narrow
industry, investors would be exposed to greater risks because the Fund's
performance would be largely dependent on that segment's performance. None of
the Funds have reserved the right to concentrate in any industry.

         FUNDAMENTAL INVESTMENT RESTRICTION (6). The 1940 Act prohibits a
diversified mutual fund from underwriting securities in excess of 25% of its
total assets.

         FUNDAMENTAL INVESTMENT RESTRICTION (7). This restriction would permit
investment in commodities, commodities contracts, futures contracts, or real
estate to the extent permitted under the 1940 Act. Each Fund has the ability to
use these investment techniques. Commodities, as opposed to commodity futures,
represent the actual underlying bulk goods, such as grains, metals and food
stuffs. Real estate-related instruments include real estate investment trusts,
commercial and residential mortgage-backed securities, and real estate
financings, and such instruments are generally sensitive to factors such as
changes in real estate values and property taxes, interest rates, cash flow of
underlying real estate assets, overbuilding, and the management skill and
creditworthiness of the issuer. If a Fund invested in these instruments it would
be exposed to the risks associated with the underlying security.

PORTFOLIO TURNOVER

         The portfolio turnover rate for each Fund is calculated by dividing the
lesser of a Fund's purchases or sales of portfolio securities for the year by
the monthly average value of the portfolio securities. The calculation excludes
all securities whose maturities at the time of acquisition were one year or
less. High portfolio turnover rates will generally result in higher transaction
costs to the Funds and may result in higher levels of taxable realized gains
(including short-term capital gains generally taxed at ordinary income tax rates
when


                                      B-23
<PAGE>   79

distributed to shareholders who are individuals) to a Fund's shareholders. The
portfolio turnover rate may vary greatly from year to year as well as within a
particular year, and may also be affected by cash requirements for redemptions
of Shares. Portfolio turnover will not be a limiting factor in making investment
decisions.

         Because securities with maturities of less than one year are excluded
from the calculation of the portfolio turnover rate, the portfolio turnover rate
for each Money Market Fund is expected to be zero for regulatory and reporting
purposes.


                                    VALUATION

         The net asset value of each Fund other than the Money Market Funds is
determined and its Shares are priced as of the close of regular trading of the
NYSE (generally 4:00 p.m. Eastern time) on each Business Day ("Valuation
Times"). The net asset value of each Money Market Fund is determined and its
Shares are priced as of 1:00 p.m. (Eastern time) and as of the close of regular
trading of the NYSE (generally 4:00 p.m., Eastern time) on each Business Day.
For each Money Market Fund, as used herein a "Business Day" constitutes (i) any
day on which the Federal Reserve Bank is open and the NYSE is open for trading
and (ii) any other day (other than a day during which no Shares are tendered for
redemption and no orders to purchase Shares are received) during which there is
sufficient trading in a Fund's portfolio instruments that the Fund's net asset
value per share might be materially affected. For each other fund, a Business
Day is (i) any day on which the NYSE is open for trading and (ii) any other day
(other than a day during which no Shares are tendered for redemption and no
orders to purchase Shares are received) during which there is sufficient trading
in a Fund's portfolio instruments that the Fund's net asset value per share
might be materially affected. Net asset value per Share for purposes of pricing
sales and redemptions is calculated by determining the value of the class's
proportional interest in the securities and other assets of a Fund, less (i)
such class's proportional share of general liabilities and (ii) the liabilities
allocable only to such class, and dividing such amount by the number of relevant

Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day and Christmas Day.

         The securities in each Fund, other than the Money Market Funds, will be
valued at market value. If market quotations are not available, the securities
will be valued by a method which the Board of Trustees believes accurately
reflects fair value.

VALUATION OF THE MONEY MARKET FUNDS

         The Money Market Funds use the amortized cost method of valuing their
securities. This involves valuing an instrument at its cost initially and
thereafter assuming a constant


                                      B-24
<PAGE>   80

amortization to maturity of any discount or premium, regardless of the impact of
fluctuating interest rates on the market value of the instrument. This method
may result in periods during which value, as determined by amortized cost, is
higher or lower than the price each Money Market Fund would receive if it sold
the instrument. The value of each Money Market Fund's securities can be expected
to vary inversely with changes in prevailing interest rates.

         Pursuant to Rule 2a-7, each Money Market Fund will maintain a
dollar-weighted average portfolio maturity appropriate to its objective of
maintaining a stable net asset value per Share, provided that the Fund will not
purchase any security with a remaining maturity of more than thirteen months
(securities subject to repurchase agreements may bear longer maturities) nor
maintain a dollar-weighted average portfolio maturity which exceeds 90 days. The
Board of Trustees has also undertaken to establish procedures reasonably
designed, taking into account current market conditions and each Money Market
Fund's investment objective, to stabilize the net asset value per Share for
purposes of sales and redemptions at $1.00. These procedures include review by
the Trustees, at such intervals as they deem appropriate, to determine the
extent, if any, to which the net asset value per Share deviates from $1.00 per
Share. In the event such deviation exceeds one-half of one percent, Rule 2a-7
requires the Board of Trustees to promptly consider what action, if any, should
be initiated. If the Board of Trustees determines that the deviation from a
$1.00 price per Share may result in material dilution or other unfair results to
Shareholders, it will take the appropriate steps to eliminate or reduce these
consequences to the extent reasonably practicable. These steps may include
selling portfolio instruments prior to maturity in order to realize capital
gains or losses to shorten the average portfolio maturity, adjusting or
withholding dividends or utilizing a net asset value per Share determined by
using available market quotations.

VALUATION OF THE INVESTMENT GRADE BOND FUND, THE GLOBAL ASSET ALLOCATION FUND,
AND THE EQUITY FUND

         Portfolio securities, the principal market for which there is a
securities exchange, will be valued at the closing sales price on that exchange
on the day of computation, or, if there have been no sales during such day, at
their latest bid quotations. If no such bid and asked prices are available, then
the securities will be valued in good faith at their respective fair market
values using methods determined by or under the supervision of the Board of
Trustees of the Eureka Funds; PROVIDED HOWEVER, that before any such securities
are purchased for any Variable NAV Fund, the Trustees of the Eureka Funds shall
be notified and given the opportunity to establish appropriate methods of
determining the fair market value of such securities.

         Portfolio securities, the principal market for which there is not a
securities exchange, will be valued at the mean between their latest bid and
asked quotations in such principal market. If no such bid and asked prices are
available, then the securities will be valued in good faith at their respective
fair market values using methods determined by or under the


                                      B-25
<PAGE>   81

supervision of the Board of Trustees of the Eureka Funds.

         All other assets and securities including securities for which market
quotations are not readily available will be valued at their fair value as
determined in good faith under the general supervision of the Board of Trustees
of the Eureka Funds; PROVIDED HOWEVER, that before any such securities are
purchased for any Variable NAV Fund, the Trustees of the Eureka Funds shall be
notified and given the opportunity to establish appropriate methods of
determining the fair market value of such securities.


         ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

HOW TO PURCHASE AND REDEEM SHARES

DISTRIBUTOR

         Shares are sold on a continuous basis by the Eureka Funds' Distributor,
BISYS Fund Services, 3435 Stelzer Road, Columbus, Ohio 43219. If you wish to
purchase Shares, contact the Eureka Funds at (888) 890-8121.

PURCHASES OF CLASS A SHARES

         Class A Shares may be purchased through procedures established by the
Distributor in connection with the requirements of qualified accounts maintained
by or on behalf of certain persons ("Customers"). All payments by the
Distributor for distribution assistance or shareholder services under the
Distribution Plan will be made pursuant to an agreement (a "Servicing
Agreement") between the Distributor and such bank, other financial institution
or intermediary, broker-dealer, or affiliate or subsidiary of the Distributor
("Participating Organizations"). Class A Shares may be purchased by
Participating Organizations under the Eureka Funds' Distribution Plan. See
"MANAGEMENT OF THE EUREKA FUNDS--Distribution Plan."

         Shares of the Eureka Funds sold to Participating Organizations acting
in a fiduciary, advisory, custodial (other than individual retirement accounts),
or other similar capacity on behalf of Customers will normally be held of record
by the Participating Organizations. With respect to Shares so sold, it is the
responsibility of the Participating Organization to transmit purchase or
redemption orders to the Distributor and to deliver federal funds for purchase
on a timely basis.

         Investors may directly purchase Class A Shares of a Fund by completing
and signing an Account Registration Form and mailing it, together with a check
(or other negotiable bank draft or money order) for at least the minimum initial
purchase amount, payable to Eureka


                                      B-26
<PAGE>   82

Funds, P.O. Box 182792, Columbus, Ohio 43218-2792. The Funds do not accept
third-party checks. Investors may obtain an Account Registration Form and
additional information regarding the Eureka Funds by contacting their local
Sanwa Bank California office or calling (888) 890-8121. Initial purchases of
shares into a new account may not be made by wire. Subsequent purchases of Class
A Shares of a Fund may be made at any time by mailing a check (or other
negotiable bank draft or money order) to the above address.

         If an Account Registration Form has been previously received by the
Distributor, investors may also purchase Class A Shares by telephone. Telephone
orders may be placed by calling the Eureka Funds at (888) 890-8121. Payment for
Class A Shares ordered by telephone may be made by sending funds electronically
to the Eureka Funds' custodian. To make payments electronically, investors must
call the Eureka Funds at (888) 890-8121 to obtain instructions regarding the
bank account number into which the funds should be wired and other pertinent
information.

         Class A Shares of the Variable NAV Funds are sold at the net asset
value next determined after receipt by the Distributor of an order in good form
to purchase Shares (see "VALUATION OF SHARES"). In the case of orders for the
purchase of Shares placed through a broker-dealer, the public offering price
will be the net asset value as so determined, but only if the broker-dealer
receives the order prior to the Valuation Time for that day and transmits to the
Eureka Funds by the Valuation Time. The broker-dealer is responsible for
transmitting such orders promptly. If the broker-dealer fails to do so, the
investor's right to that day's closing price must be settled between the
investor and the broker-dealer. If the broker-dealer receives the order after
the Valuation Time for that day, the price will be based on the net asset value
determined as of the Valuation Time for the next Business Day.

         There is a minimum initial investment of $1,000 for the purchase of
Class A Shares of a Fund, and a $50 minimum for subsequent purchases. The
minimum initial investment amount is $50 if purchases are made in connection
with qualified retirement plans (401(k) and 403(b) accounts only), systematic
investment plans or payroll deduction plans. There is no limit on the amount of
Class A Shares that may be purchased.

         Shareholders will be mailed a confirmation of each new transaction in
their account. In the case of Class A Shares held of record by a Participating
Organization but beneficially owned by a Customer, confirmations of purchases,
exchanges and redemptions of Class A Shares by a Participating Organization will
be sent to the Customer by the Participating Organization. Certificates
representing Shares will not be issued.

EUREKA FUNDS INDIVIDUAL RETIREMENT ACCOUNT ("IRA")

         The Eureka Funds make available IRAs, including IRAs set up under a
Simplified Employee Pension Plan ("SEP-IRAs") and IRA "Rollover Accounts." An
IRA enables individuals, even if they participate in an employer-sponsored
retirement plan, to establish their own retirement program by purchasing Class A
Shares for an IRA. Eureka Funds IRA contributions may be tax-deductible and
earnings are tax deferred. Under the Tax Reform Act of 1986, the tax
deductibility of IRA contributions is restricted or eliminated for individuals
who participate in certain employer pension plans and whose annual income
exceeds certain limits. Existing IRAs and future contributions up to the IRA
maximums, whether deductible or not, still earn income on a tax-deferred basis.

         The Eureka Funds also make available the Roth IRA. Unlike a traditional
IRA, contributions to a Roth IRA are not tax deductible. However, distributions
are generally excluded from income provided they occur at least five years after
the creation of the Roth IRA and the distribution is (1) made on or after the
date on which the individual attains age 59 1/2; (2) made to a beneficiary (or
the individual's estate) on or after the individual's death; (3) attributable to
the individual being disabled; or (4) a "qualified first-time home buyer
distribution," subject to a $10,000 limit.

         Trust Shares of the Eureka Funds IRAs are available to employees of
SBCL, employees of BISYS Fund Services and Trustees of the Eureka Funds; the
minimum initial investment in an IRA is $500 and there is no minimum subsequent
investment requirement. Class A Shares of the Eureka Funds IRAs are available to
all shareholders; the minimum investment in an IRA is $1,000 and the minimum for
subsequent investments is $50.

         BISYS Fund Services, Inc. serves as transfer agent to each Fund
pursuant to a Transfer Agency Agreement. All Eureka Funds IRA distribution
requests must be made in writing to BISYS Fund Services, Inc. (the "Transfer
Agent"). Any additional deposits to a Eureka Funds IRA must distinguish the type
and year of the contribution.

         For more information on a Eureka Funds IRA call the Eureka Funds at
(888) 890-8121. Shareholders are advised to consult a tax adviser on Eureka
Funds IRA contribution and withdrawal requirements and restrictions.
Shareholders should read the Disclosure Statement and Custodial Agreement for
further details on eligibility, service fees, and tax implications.

ADDITIONAL INFORMATION ABOUT PURCHASING SHARES

         Purchases of Class A Shares of the Eureka Funds will be effected only
on a Business Day (as defined in "VALUATION"). An order for a Money Market Fund
received prior to a Valuation Time on any Business Day will be executed at the
net asset value determined as of the next Valuation Time on the date of receipt.
An order for a Money Market Fund received


                                      B-28
<PAGE>   84

after the last Valuation Time on any Business Day will be executed at the net
asset value determined as of the next Valuation Time on the next Business Day.
An order for any Fund other than a Money Market Fund received prior to the
Valuation Time on any Business Day will be executed at the net asset value
determined as of the Valuation Time on the date of receipt. An order for any
Fund other than a Money Market Fund received after the Valuation Time on any
Business Day will be executed at the net asset value determined as of the
Valuation Time on the Business Day.

         An order to purchase Class A Shares of a Money Market Fund will be
deemed to have been received by the Distributor when federal funds are available
to the Eureka Funds' custodian for investment. Federal funds are monies credited
to a bank's account within a Federal Reserve Bank. Payment for an order to
purchase Shares of a Money Market Fund which is transmitted by federal funds
wire will be available the same day for investment by the Eureka Funds'
custodian, if received prior to the last Valuation Time (see "VALUATION"). It is
strongly recommended that investors of substantial amounts use federal funds to
purchase Shares of a Money Market Fund.

         Shares of a Money Market Fund purchased before 1:00 p.m., Eastern time,
begin earning dividends on the same Business Day. All Shares of a Money Market
Fund continue to earn dividends through the day before their redemption.

         Depending upon the terms of a particular Customer account, a
Participating Organization or Bank may charge a Customer's account fees for
services provided in connection with investment in the Eureka Funds. Information
concerning this Prospectus should be read in conjunction with any such
information received from the Participating Organizations or Banks.

         The Eureka Funds reserve the right to reject any order for the purchase
of its Class A Shares in whole or in part, including purchases made with foreign
drafts or checks. The Eureka Funds will not accept third party checks for
investment.

         Please call the Eureka Funds at (888) 890-8121 regarding proper
instructions and information to purchase or redeem Shares by check or wire.
Shareholders may also execute telephone transactions as explained below.

REDEMPTION OF SHARES

         Shareholders may redeem their Class A Shares without charge on any day
that net asset value is calculated (see "VALUATION") and Shares may ordinarily
be redeemed by mail or by telephone. However, all or part of a Customer's Shares
may be required to be redeemed in accordance with instructions and limitations
pertaining to his or her account held by a Participating Organization or Bank.
For example, if a Customer has agreed to maintain a


                                      B-29
<PAGE>   85

minimum balance in his or her account, and the balance in that account falls
below that minimum, the Customer may be obliged to redeem, or the Participating
Organization or Bank may redeem for and on behalf of the Customer, all or part
of the Customer's Shares to the extent necessary to maintain the required
minimum balance.

         Each Fund reserves the right to redeem a shareholder's Class A Shares
if the Shareholder does not maintain a balance of $1,000 in the Class A Shares
of that Fund.

REDEMPTION BY MAIL

         A written request for redemption must be received by the Eureka Funds
in order to constitute a valid tender for redemption. The signature on the
written request must be guaranteed by a bank, broker, dealer, credit union,
securities exchange, securities association, clearing agency or savings
association, as those terms are defined in Rule 17Ad-15 under the Securities
Exchange Act of 1934 if (a) a redemption check is to be payable to anyone other
than the Shareholder(s) of record; or (b) a redemption check is to be mailed to
the Shareholder(s) at an address other than the address of record or other than
to a commercial bank designated on the Account Registration Form of such
Shareholder(s). The Distributor reserves the right to reject any signature
guarantee if (1) it has reason to believe that the signature is not genuine, (2)
it has reason to believe that the transaction would otherwise be improper, or
(3) the guarantor institution is a broker or dealer that is neither a member of
a clearing corporation nor maintains net capital of at least $100,000. A
signature notarized by a notary public will not be accepted as a signature
guarantee. Proceeds may be mailed to the address of record or sent
electronically or mailed to a previously designated bank account without a
signature guarantee. See "Redemption by Telephone" for further discussion
regarding sending proceeds to your bank account.

REDEMPTION BY TELEPHONE

         Shares may be redeemed by telephone if the Shareholder selected that
option on the Account Registration Form or in a subsequent written request to
the Transfer Agent. A Shareholder may have the proceeds mailed to the address of
record or sent electronically or mailed directly to a domestic commercial bank
account previously designated by the Shareholder on the Account Registration
Form. Under most circumstances, such payments will be transmitted on the next
Business Day following receipt of a valid request for redemption. Such
electronic redemption requests may be made by the Shareholder by telephone to
the Transfer Agent. The Transfer Agent may reduce the amount of a wire
redemption payment by its then-current wire redemption charge. Presently there
is no charge. There is no charge for having payment of redemption requests
mailed or sent via the Automated Clearing House to a designated bank account.
For telephone redemptions, contact the Funds at (888) 890-8121.


                                      B-30
<PAGE>   86


TELEPHONE PROCEDURES

         A change of address may be requested over the telephone or by fax.
These requests will be processed and subject to independent verification at the
point of entry. Telephone and faxed address changes may not be made in
conjunction with a redemption request or a change in Auto Invest/Auto Withdrawal
instructions. A Shareholder that changes his or her address by phone will have
their account subject to a ten business day escrow hold.

         The Distributor, the Transfer Agent, SBCL and the Eureka Funds will not
be liable for any losses, damages, expenses or costs arising out of any
telephone transaction (including purchases, exchanges, and redemptions) effected
in accordance with the Eureka Funds' telephone transaction procedures, upon
instructions reasonably believed to be genuine. The Eureka Funds will employ
procedures designed to provide reasonable assurance that instructions
communicated by telephone are genuine; if these procedures are followed, the
Eureka Funds will not be liable for any losses due to unauthorized or fraudulent
instructions. These procedures include recording phone conversations, sending
confirmations to Shareholders within 72 hours of the telephone transaction,
verifying the account name and a Shareholder's account number or tax
identification number and sending redemption proceeds only to the address of
record or to a previously authorized bank account. If, due to temporary adverse
conditions, Shareholders are unable to effect telephone transactions,
Shareholders may mail redemption requests to the Eureka Funds.

PAYMENTS TO SHAREHOLDERS

         Redemption orders are effected at the net asset value per Share next
determined after the Shares are properly tendered for redemption, as described
above. Payment to Shareholders for Shares redeemed will be made within seven
days after receipt by the Distributor of the request for redemption. However, to
the greatest extent possible, the Eureka Funds will attempt to honor requests
from Shareholders for next Business Day payments if the request for redemption
is received by the Transfer Agent before the Valuation Time on a Business Day
or, if the request for redemption is received after the Valuation Time, to honor
requests for payment within two Business Days, unless it would be
disadvantageous to the Eureka Funds or the Shareholders of the particular Fund
to sell or liquidate portfolio securities in an amount sufficient to satisfy
requests for payments in that manner. The Money Market Funds will attempt to
honor requests from Shareholders for same day payment upon redemption of Shares
if the request for redemption is received by the Transfer Agent before 1:00 p.m.
Eastern time, on a Business Day or, if the request for redemption is received
after 1:00 p.m. Eastern time, to honor requests for payment on the next Business
Day, unless it would be disadvantageous to the Fund or its Shareholders to sell
or liquidate portfolio securities in an amount sufficient to satisfy requests
for payments in that manner.


                                      B-31
<PAGE>   87


         In some instances, a Fund may be requested to redeem Shares for which
it has not yet received good payment. Under such circumstances, the Eureka Funds
may delay forwarding the proceeds until payment has been collected for the
purchase of such Shares, which may take up to 15 days or more. To avoid delay in
payment upon redemption, investors should purchase Shares by certified check or
by wire transfer. The Eureka Funds intend to pay cash for all Shares redeemed,
but under abnormal conditions which may make payment in cash unwise, the Eureka
Funds may make payment wholly or partly in portfolio securities at their then
current market value equal to the redemption price. In such cases, an investor
may incur brokerage costs in converting such securities to cash.

         Due to the relatively high cost of handling small investments, the
Eureka Funds reserve the right to redeem, at net asset value, the Shares in an
account with a value of less than $1,000. Accordingly, an investor purchasing
Shares of a Fund in only the minimum investment amount may be subject to such
involuntary redemption if he thereafter redeems some of his Shares. Before the
Eureka Funds exercises its right to redeem such Shares, the Shareholder will be
given notice that the value of his Shares of a Fund is less than the minimum
amount and will be allowed 60 days to make an additional investment to increase
the value of the account to at least $1,000.

         Each class of Shares of the Funds are sold on a continuous basis by
BISYS Fund Services Limited Partnership d/b/a/ BISYS Fund Services. In addition
to purchasing Shares directly from BISYS Fund Services, Class A or Trust Shares
may be purchased through procedures established by BISYS Fund Services in
connection with the requirements of accounts at SBCL, or SBCL's affiliated or
correspondent banks. Customers purchasing Shares of the Eureka Funds may include
officers, directors, employees of SBCL or SBCL's affiliated or correspondent
banks, employees of BISYS Fund Services or Trustees of the Eureka Funds.

MATTERS AFFECTING REDEMPTION

         The Eureka Funds may suspend the right of redemption or postpone the
date of payment for Shares during any period when (a) trading on the NYSE is
restricted by applicable rules and regulations of the Securities and Exchange
Commission, (b) the NYSE is closed for other than customary weekend and holiday
closings, (c) the Securities and Exchange Commission has by order permitted such
suspension, or (d) an emergency exists as a result of which (i) disposal by the
Eureka Funds of securities owned by it is not reasonably practical or (ii) it is
not reasonably practical for the Company to determine the fair market value of
its total net assets.

         The Eureka Funds may redeem any class of Shares involuntarily if
redemption appears appropriate. See "Valuation of the Money Market Funds" above.

                           ADDITIONAL TAX INFORMATION

DIVIDENDS AND TAXES

         Each Fund will be treated as a separate entity for federal income tax
purposes. Each Fund intends to qualify for treatment as a "regulated investment
company" under the Internal Revenue Code of 1986, as amended (the "Code"). If
qualified, a Fund will not have to pay federal taxes on amounts it distributes
to Shareholders. Regulated investment companies are subject to a federal excise
tax if they do not distribute substantially all of their income on a timely
basis. Each Fund intends to avoid paying federal income and excise taxes by
timely distributing substantially all its net income and net realized capital
gains.

         Shareholders will be advised at least annually as to the amount and
federal income tax character of distributions made during the year.

         The net investment income of each Money Market Fund is declared daily
as a dividend to Shareholders at the close of business on the day of
declaration. Dividends will generally be paid monthly. The Money Market Funds do
not expect to realize any long-term capital gains and, therefore, do not foresee
paying any "capital gains dividends" as described in the Code. However, any such
capital gains will be distributed no more than twice a year after deduction for
any available capital loss carryforward.

         The amount of dividends payable with respect to the Trust Shares will
exceed dividends on Class A Shares due to the Distribution and Shareholder
Services Plan fee and Services Plan fee applicable to Class A Shares.

         Dividends on the Shares of the Investment Grade Bond Fund are declared
daily and paid monthly. A dividend on the Shares of the Global Asset Allocation
Fund is declared and paid annually. A dividend on the Shares of the Equity Fund
is declared and paid monthly. Net realized capital gains, if any, are
distributed at least annually to Shareholders of record after deduction for any
available capital loss carryforward.

         A Shareholder will automatically receive all income dividends and
capital gain distributions in additional full and fractional Shares at net asset
value as of the date of payment unless the Shareholder elects to receive such
dividends or distributions in cash. Such election, or any revocation thereof,
must be made in writing to the Eureka Funds, P.O. Box 182792, Columbus, Ohio
43218-2792, and will become effective with respect to dividends and
distributions having record dates after its receipt by the Transfer Agent.
Reinvested dividends receive the same tax treatment as dividends paid in cash.
Dividends are paid in cash not later than seven Business Days after a
Shareholder's complete redemption of his or her Shares. If you elect to receive
distributions in cash, and checks (1) are returned and marked as "undeliverable"
or (2) remain uncashed for six months, your cash election will be changed


                                      B-33
<PAGE>   89

automatically and your future dividend and capital gains distributions will be
reinvested in the Fund at the per share net asset value determined as of the
date of payment of the distribution. In addition, any undeliverable checks or
checks that remain uncashed for six months will be canceled and will be held in
a non-interest bearing account pending further instructions from the
Shareholder.

         Dividends are generally taxable in the taxable year received. However,
dividends declared in October, November or December to Shareholders of record
during such a month and paid during the following January are treated for tax
purposes as if they were received by each Shareholder on December 31 of the year
in which the dividends were declared.

         Dividends will generally be taxable to a Shareholder as ordinary income
to the extent of the Shareholder's ratable share of the earnings and profits of
a Fund as determined for tax purposes. Certain dividends paid by the Investment
Grade Bond Fund, the Global Asset Allocation Fund, and the Equity Fund, and
so-designated by the Funds may qualify for the dividends received deduction for
corporate shareholders. Because all of the net investment income of the
remaining Funds is expected to be interest income, it is anticipated that no
distributions from such Funds will qualify for the dividends received deduction.
Distributions of net realized capital gains are taxable to Shareholders as
long-term capital gains regardless of how long the Shareholder has held Shares
in the Fund. Shareholders who are not subject to tax on their income generally
will not have to pay federal income tax on amounts distributed to them.

         Dividends and distributions on a Fund's shares are generally subject to
federal income tax as described herein to the extent they do not exceed the
Fund's realized income and gains, even though such dividends and distributions
may economically represent a return of a particular shareholder's investment.
Such distributions are likely to occur in respect of shares purchased at a time
when a Fund's net asset value reflects gains that are either unrealized, or
realized but not distributed. Such realized gains may be required to be
distributed even when a Fund's net asset value also reflects unrealized losses.

         Dividends received by a Shareholder of a Fund that are derived from
such Fund's investments in U.S. government agency securities may not be entitled
to the exemption from state and local income taxes that would be available if
the Shareholder had purchased U.S. government agency securities directly.
Distributions of income derived from repurchase agreements and securities
lending transactions generally will not qualify for exemption from state and
local income taxes.

         The foregoing is a summary of certain federal income tax consequences
of investing in a Fund. Shareholders should consult their own tax advisers
concerning the tax consequences of an investment in a Fund including the
application of state and local taxes to distributions received from a Fund.

GENERAL

         It is the policy of each of the Funds to qualify for the favorable tax
treatment accorded regulated investment companies (a "RIC") under Subchapter M
of the Code. By qualifying as a RIC, each Fund expects to eliminate or reduce to
a nominal amount its federal income taxes.

         In order to qualify as a RIC and to qualify for the favorable tax
treatment accorded RICs and their shareholders, a Fund must (a) derive at least
90% of its gross income from dividends, interest, payments with respect to
certain securities loans, and gains from the sale of stock, securities, and
foreign currencies, or other income (including but not limited to gains from
options, futures, or forward contracts) derived with respect to its business of
investing in such stock, securities, or currencies; (b) distribute each year at
least 90% of its dividend, interest (including tax-exempt interest), and certain
other income and the excess, if any, of its net short-term capital gains over
its net long-term capital losses; and (c) diversify its holdings so that, at the
end of each fiscal quarter (i) at least 50% of the market value of its assets is
represented by cash, cash items, U.S. government securities, securities of other
RICs, and other securities, limited in respect of any one issuer to a value not
greater than 5% of the value of the Fund's total assets and 10% of the
outstanding voting securities of such issuer, and (ii) not more than 25% of the
value of its assets is invested in the securities (other than those of the U.S.
government or other RICs) of any one issuer or of two or more issuers which the
Fund controls and which are engaged in the same, similar, or related trades or
businesses.

         A non-deductible excise tax is imposed on RICs that do not distribute
in each calendar year (regardless of whether they have a non-calendar taxable
year) an amount at least equal to (i) 98% of their "ordinary income" (as
defined) for the calendar year plus (ii) 98% of their capital gain net income
for the 12 month period ending on October 31 of such calendar year plus (iii)
any undistributed amounts from prior years. For the foregoing purposes, a Fund
is treated as having distributed any amount on which it is subject to income tax
for any taxable year ending in such calendar year. If distributions during a
calendar year by a Fund were less than the required amount, the Fund would be
subject to a non-deductible excise tax equal to 4% of the deficiency.

         Each Fund will be required in certain cases to withhold and remit to
the U.S. Treasury 31% of taxable dividends and other distributions paid to any
Shareholder who has provided either an incorrect taxpayer identification number
or no number at all, who is subject to withholding by the Internal Revenue
Service for failure properly to report payments of interest or dividends, or who
fails to provide a certified statement that he or she is not subject to "backup
withholding."

         A Fund's transactions in futures contracts, options, and
foreign-currency-denominated securities, and certain other investment and
hedging activities of the Fund, will be subject to special tax rules (including
"mark-to-market," "straddle," "wash sale," "constructive sale" and


                                      B-35

"short sale" rules), the effect of which may be to accelerate income to the
Fund, defer losses to the Fund, cause adjustments in the holding periods of the
Fund's assets, convert short-term capital losses into long-term capital losses,
convert long-term capital gains into short-term capital gains and otherwise
affect the character of the Fund's income. These rules could therefore affect
the amount, timing, and character of distributions to Shareholders. Income
earned as a result of these transactions would, in general, not be eligible for
the dividends received deduction or for treatment as exempt-interest dividends
when distributed to Shareholders. The Funds will endeavor to make any available
elections pertaining to these transactions in a manner believed to be in the
best interest of the Funds.

         Investment by the Fund in "passive foreign investment companies" could
subject the Fund to federal income tax or other charge on the proceeds from the
sale of its investment in such a company; however, this tax can be avoided by
making an election to mark such investments to market annually or to treat the
passive foreign investment company as a "qualified electing fund."

         A "passive foreign investment company" is any foreign corporation: (i)
75 percent or more of the income of which for the taxable year is passive
income, or (ii) the average percentage of the assets of which (generally by
value, but by adjusted tax basis in certain cases) that produce or are held for
the production of passive income is at least 50 percent. Generally, passive
income for this purpose means dividends, interest (including income equivalent
to interest), royalties, rents, annuities, the excess of gains over losses from
certain property transactions and commodities transactions, and foreign currency
gains. Passive income for this purpose does not include rents and royalties
received by the foreign corporation from active business and certain income
received from related persons.

         Although each Fund expects to qualify as a RIC and to be relieved of
all or substantially all Federal income taxes, depending upon the extent of
their activities in states and localities in which their offices are maintained,
in which their agents or independent contractors are located, or in which they
are otherwise deemed to be conducting business, the Funds may be subject to the
tax laws of such states or localities. If for any taxable year a Fund does not
qualify for the special federal tax treatment accorded a RIC, all of its taxable
income will be subject to federal income tax at regular corporate rates at the
Fund level (without any deduction for distributions to its Shareholders). In
addition, distributions to Shareholders will be taxed as ordinary income even if
the distributions are attributable to capital gains or exempt interest earned by
the Fund.

         Information set forth in the Prospectuses and this Statement of
Additional Information which relates to federal taxation is only a summary of
some of the important federal tax considerations generally affecting purchasers
of Shares of the Funds. No attempt has been made to present a detailed
explanation of the federal income tax treatment of a Fund or its Shareholders
and this discussion is not intended as a substitute for careful tax planning.


                                      B-36

Accordingly, potential purchasers of Shares of a Fund are urged to consult their
tax advisers. In addition, the tax discussion in the Prospectuses and this
Statement of Additional Information is based on tax laws and regulations which
are in effect on the date of the Prospectuses and this Statement of Additional
Information; such laws and regulations may be changed by legislative or
administrative action.

ADDITIONAL TAX INFORMATION CONCERNING THE GLOBAL ASSET ALLOCATION FUND

         Dividends and certain interest income earned by the Global Asset
Allocation Fund from foreign securities may be subject to foreign withholding
taxes or other taxes. So long as more than 50% of the value of the Fund's total
assets at the close of any taxable year consists of stock or securities of
foreign corporations, the Fund may elect, for federal income tax purposes, to
treat certain foreign taxes paid by it, including generally any withholding
taxes and other foreign income taxes, as paid by its shareholders. It is
possible that the Global Asset Allocation Fund will make this election in
certain years. The remaining Funds do not expect to be eligible to make this
election. If a Fund makes the election, the amount of such foreign taxes paid by
a Fund will be included in its shareholders' income pro rata (in addition to
taxable distributions actually received by them). A shareholder's ability to
claim a foreign tax credit or deduction in respect of foreign taxes paid by the
Fund may be subject to certain limitations imposed by the Code, as a result of
which a shareholder may not get a full credit or deduction for the amount of
such taxes. Shareholders who do not itemize on their federal income tax returns
may claim a credit (but no deduction) for such foreign taxes.

         The Global Asset Allocation Fund's transactions in foreign currencies
and hedging activities may give rise to ordinary income or loss to the extent
such income or loss results from fluctuations in value of the foreign currency
concerned. In addition, such activities will likely produce a difference between
book income and taxable income. This difference may cause a portion of a Fund's
income distributions to constitute a return of capital for tax purposes or
require the Fund to make distributions exceeding book income to qualify as a
regulated investment company for tax purposes.


                         MANAGEMENT OF THE EUREKA FUNDS

TRUSTEES AND OFFICERS

         The Board of Trustees of the Eureka Funds has overall responsibility
for the Funds. The Board of Trustees is elected by the Shareholders. There are
currently five Trustees, two of whom are "interested persons" of the Eureka
Funds within the meaning of that term under the 1940 Act. The Trustees, in turn,
elect the officers of the Eureka Funds to supervise its day-to-day operations.

         Investment advisory and management services are provided to each Fund
by SBCL pursuant to an Investment Advisory Agreement ("Advisory Agreement")
dated October 21, 1997.

         The Advisory Agreement provides that SBCL shall not be liable for any
error of judgment or mistake of law or for any loss suffered by the Eureka Funds
in connection with the performance of such Advisory Agreement, except a loss
resulting from a breach of fiduciary duty under the 1940 Act with respect to the
receipt of compensation for services or a loss resulting from willful
misfeasance, bad faith, or gross negligence on the part of SBCL in the
performance of its duties, or from reckless disregard by SBCL of its obligations
and duties under the Advisory Agreement.

         The Advisory Agreement will continue in effect until May 31, 2000, and
if not terminated, shall continue in effect as to a particular Fund for
successive periods of twelve months, provided such continuance is specifically
approved at least annually (a) by the vote of a majority of those members of the
Trust's Board of Trustees who are not parties to the Advisory Agreement or
interested persons of any party to the Advisory Agreement, cast in person at a
meeting called for the purpose of voting on such approval, and (b) by the vote
of a majority of the Trust's Board of Trustees or by the vote of a majority of
the outstanding voting securities of such Fund. The Advisory Agreement is
terminable as to a particular Fund at any time on 60 days written notice,
without the payment of any penalty, by the Trust (by vote of the Trust's Board
of Trustees or by the vote of a majority of the outstanding voting securities of
such Fund) or by SBCL. The Advisory Agreement will immediately terminate in the
event of its assignment, as defined in the 1940 Act.

         Under an investment advisory agreement between the Eureka Funds and
SBCL, the fee payable to SBCL by each Fund for investment advisory services is
the lesser of: (a) a fee computed daily and paid monthly at the annual rate of
thirty one-hundredths of one percent (0.30%) of the Prime Money Market Fund's
average daily net assets; twenty one-hundredths of one percent (0.20%) of the
U.S. Treasury Obligations Fund's average daily net assets; sixty one-hundredths
of one percent (0.60%) of the Investment Grade Bond Fund's average daily net
assets; ninety one-hundredths of one percent (0.90%) of the Global Asset
Allocation Fund's average daily net assets; and seventy five one-hundredths of
one percent (0.75%) of the Equity Fund's average daily net assets, or (b) such
fee as may from time to time be agreed upon by the Eureka Funds and SBCL. The
fee agreed to from time to time by the Eureka Funds and SBCL may be
significantly lower than the fee calculated at the annual rate and the effect of
such agreed upon lower fee would be to lower a Fund's expenses and increase the
net income of the Fund during the period when such agreed upon lower fee is in
effect.

PORTFOLIO TRANSACTIONS

         Pursuant to the Advisory Agreement, SBCL determines, subject to the
general supervision of the Board of Trustees and in accordance with each Fund's
investment objective and restrictions, which securities are to be purchased and
sold by a Fund, and which brokers are to be eligible to execute portfolio
transactions. Purchases and sales of portfolio securities with respect to the
Funds usually are principal transactions in which portfolio securities are
purchased directly from the issuer or from an underwriter or market maker for
the securities. Purchases from underwriters of portfolio securities generally
include (but not in the case of mutual fund shares purchased by the Funds) a
commission or concession paid by the issuer to the underwriter and purchases
from dealers serving as market makers may include the spread between the bid and
asked price. Transactions on stock exchanges involve the payment of negotiated
brokerage commissions. Transactions in the over-the-counter market are generally
principal transactions with dealers. With respect to the over-the-counter
market, the Eureka Funds, where possible, will deal directly with dealers who
make a market in the securities involved unless better price and execution are
available elsewhere. While SBCL generally seeks competitive spreads or
commissions, the Eureka Funds may not necessarily pay the lowest spread or
commission available on each transaction, for reasons discussed below.

         Allocation of transactions, including their frequency, to various
dealers is determined by SBCL in its best judgment and in a manner deemed fair
and reasonable to Shareholders. The major consideration in allocating brokerage
business is the assurance that the best execution is being received on all
transactions. Brokerage will at times be allocated to firms that supply
research, statistical data and similar services when the terms of the
transaction and the capabilities of different broker/dealers are consistent with
the guidelines set forth in Section 28(e) of the Securities Exchange Act of
1934. Information so received is in addition to, and not in lieu of, services
required to be performed by SBCL and does not reduce the advisory fees payable
to SBCL. Such information may be useful to SBCL in serving both the Eureka Funds
and other clients and, conversely, supplemental information obtained by the
placement


                                      B-42
<PAGE>   98

of business of other clients may be useful to SBCL in carrying out its
obligations to the Eureka Funds.

         Except as otherwise disclosed to the Shareholders of the Funds and as
permitted by applicable rules and regulations, SBCL will not execute portfolio
transactions on behalf of the Funds through, acquire portfolio securities issued
by, make savings deposits in, or enter into repurchase or reverse repurchase
agreements with SBCL, BISYS Fund Services, or their affiliates, and will not
give preference to SBCL's correspondents with respect to such transactions,
securities, savings deposits, repurchase agreements, and reverse repurchase
agreements.

         Investment decisions for each Fund are made independently from those
for the other Funds or any other investment company or account managed by SBCL.
Other investment companies or accounts may also invest in the same securities as
the Eureka Funds. When a purchase or sale of the same security is made at
substantially the same time on behalf of a Fund and another Fund of the Eureka
Funds, investment company or account, the transaction will be averaged as to
price and available investments will be allocated as to amount in a manner which
SBCL believes to be equitable to the Fund(s) and such other investment company
or account. In some instances, this investment procedure may adversely affect
the price paid or received by a Fund or the size of the position obtained by a
Fund. To the extent permitted by law, SBCL may aggregate the securities to be
sold or purchased for a Fund with those to be sold or purchased for the other
Funds or for other investment companies or accounts in order to obtain best
execution. As provided by the Advisory Agreement, in making investment
recommendations for the Eureka Funds, SBCL will not inquire or take into
consideration whether an issuer of securities proposed for purchase or sale by
the Eureka Funds is a customer of SBCL or their parents, subsidiaries, or
affiliates, and, in dealing with their customers, SBCL and their parents,
subsidiaries, and affiliates will not inquire or take into consideration whether
securities of such customers are held by the Eureka Funds.

         In determining when and to what extent to use Sanwa Universal
Securities, LLC, Sanwa Futures LLC or any other affiliated broker-dealer as its
broker for executing orders for the Funds on securities exchanges, SBCL will
consider (if relevant) whether the compensation to be paid Sanwa Universal
Securities, LLC, Sanwa Futures LLC or any other affiliated broker-dealer will be
(i) fair and reasonable, (ii) at least as favorable to the Funds as commissions
that would be charged by other qualified brokers having comparable execution
capabilities and (iii) at least as favorable as commissions contemporaneously
charged by Sanwa Universal Securities, LLC, Sanwa Futures LLC or any other
affiliated broker-dealer on comparable transactions for its most favored
unaffiliated customers. The Funds do not consider it practicable or in the best
interests of their shareholders to solicit competitive bids for commission rates
on each transaction. However, the Board of Trustees, including a majority of the
Trustees who are not "interested persons" of Sanwa Universal Securities, LLC,
Sanwa Futures LLC or any other affiliated broker-dealer within the meaning of
the 1940 Act,


                                      B-43
<PAGE>   99

(i) has prescribed procedures designed to provide that the Funds
do not pay commissions that do not meet the standards described above, (ii)
reviews those procedures annually to determine whether they remain adequate and
(iii) considers quarterly whether or not the commissions charged by Sanwa
Universal Securities, LLC, Sanwa Futures LLC or any other affiliated
broker-dealer have met the standards.

         Brokerage services Sanwa Universal Securities, LLC, or Sanwa Futures
LLC provides to the Funds are also subject to Rule 11a2-2(T) under the
Securities Exchange Act of 1934, as amended. Rule 11a2-2(T) permits the Funds to
use Sanwa Universal Securities, LLC, or Sanwa Futures LLC as a broker provided
certain conditions are met. Among these requirements are that members of the
exchange not associated with Sanwa Universal Securities, LLC, or Sanwa Futures
LLC perform the floor brokerage element of portfolio transactions (that is,
execution on the exchange floor or through use of exchange facilities) that the
orders to such members be transmitted from off the exchange floor and that
neither Sanwa Universal Securities, LLC, Sanwa Futures LLC nor an associated
person of Sanwa Universal Securities, LLC, or Sanwa Futures LLC participates in
the execution of the transaction after the order has been so transmitted. In
connection with transactions in which Sanwa Universal Securities, LLC, or Sanwa
Futures LLC acts as broker for the Funds, Sanwa Universal Securities, LLC, or
Sanwa Futures LLC, while not permitted to perform floor brokerage (which is
undertaken by members Sanwa Universal Securities, LLC, or Sanwa Futures LLC
selects who are not associated with that firm), still continues to bear
principal responsibility for determining important elements of overall execution
such as timing and order size, and also clears and settles such transactions.
Sanwa Universal Securities, LLC, or Sanwa Futures LLC pays the fees charged by
those persons performing the described floor brokerage elements. Sanwa Universal
Securities, LLC, or Sanwa Futures LLC will not trade directly with the Funds in
any transactions in which Sanwa Universal Securities, LLC, or Sanwa Futures LLC
or an affiliate acts as principal.

The Funds paid aggregate brokerage commissions in the following amounts:

GLASS-STEAGALL ACT

         In 1971, the United States Supreme Court held in INVESTMENT COMPANY
INSTITUTE V. CAMP that the Federal statute commonly referred to as the
Glass-Steagall Act prohibits a bank from operating a mutual fund for the
collective investment of managing agency accounts.


                                      B-44
<PAGE>   100

Subsequently, the Board of Governors of the Federal Reserve System (the "Board")
issued a regulation and interpretation to the effect that the Glass-Steagall Act
and such decision: (a) forbid a bank holding company registered under the
Federal Bank Holding Company Act of 1956 (the "Holding Company Act") or any
non-bank affiliate thereof from sponsoring, organizing, or controlling a
registered, open-end investment company continuously engaged in the issuance of
its shares, but (b) do not prohibit such a holding company or affiliate from
acting as investment adviser, transfer agent, and custodian to such an
investment company. In 1981, the United States Supreme Court held in BOARD OF
GOVERNORS OF THE FEDERAL RESERVE SYSTEM V. INVESTMENT COMPANY INSTITUTE that the
Board did not exceed its authority under the Holding Company Act when it adopted
its regulation and interpretation authorizing bank holding companies and their
non-bank affiliates to act as investment advisers to registered closed-end
investment companies. In the BOARD OF GOVERNORS case, the Supreme Court also
stated that if a bank complied with the restrictions imposed by the Board in its
regulation and interpretation authorizing bank holding companies and their
non-bank affiliates to act as investment advisers to investment companies, a
bank performing investment advisory services for an investment company would not
violate the Glass-Steagall Act.

         SBCL believes that they possess the legal authority to perform the
services for each Fund contemplated by the Advisory Agreement and described in
the Prospectuses and this Statement of Additional Information and has so
represented in the Advisory Agreement. Future changes in either federal or state
statutes and regulations relating to the permissible activities of banks or bank
holding companies and the subsidiaries or affiliates of those entities, as well
as further judicial or administrative decisions or interpretations of present
and future statutes and regulations, could prevent or restrict SBCL from
continuing to perform such services for the Eureka Funds. Depending upon the
nature of any changes in the services which could be provided by SBCL, the Board
of Trustees of the Eureka Funds would review the Eureka Funds' relationship with
SBCL and consider taking all action necessary in the circumstances.

         Should future legislative, judicial, or administrative action prohibit
or restrict the proposed activities of SBCL or their affiliated and
correspondent banks (the "Banks") in connection with Customer's purchases of
Shares of the Eureka Funds, the Banks might be required to alter materially or
discontinue the services offered by them to Customers. It is not anticipated,
however, that any change in the Eureka Funds' method of operations would affect
its net asset value per Share or result in financial losses to any Customer.

ADMINISTRATOR

         BISYS Fund Services serves as administrator (the "Administrator") to
each Fund pursuant to the Administration Agreement dated as of October 21, 1997.
The Administrator assists in supervising operations of each Fund (other than
those performed by SBCL under the Advisory Agreement, those performed by The
Bank of New York under its custodial services agreements with the Eureka Funds,
and those performed by BISYS Fund Services, Inc. under


                                      B-45
<PAGE>   101

its transfer agency, shareholder service and fund accounting agreements with
the Eureka Funds). The Administrator is a broker-dealer registered with the
Securities and Exchange Commission, and is a member of the National Association
of Securities Dealers, Inc. The Administrator provides financial services to
institutional clients.

         Under the Administration Agreement, the Administrator has agreed to
monitor the net asset value of the Money Market Funds, to maintain office
facilities for the Eureka Funds, to maintain the Eureka Funds' financial
accounts and records, and to furnish the Eureka Funds statistical and research
data and certain bookkeeping services, and certain other services required by
the Eureka Funds. The Administrator prepares annual and semi-annual reports to
the Securities and Exchange Commission, prepares federal and state tax returns,
prepares filings with state securities commissions, and generally assists in
supervising all aspects of the Eureka Funds' operations (other than those
performed by SBCL under the Advisory Agreement, and those performed by The Bank
of New York, under its custodial services agreements with the Eureka Funds, and
those performed by BISYS Fund Services, Inc. under its transfer agency,
shareholder service and fund accounting agreements with the Eureka Funds). Under
the Administration Agreement, the Administrator may delegate all or any part of
its responsibilities thereunder.

         Under the Administration Agreement, the Administrator receives a fee
from each Fund equal to the lesser of (a) a fee computed at the annual rate set
forth below, subject to a per Fund annual minimum of $75,000: twenty
one-hundredths of one percent (0.20%) of a Fund's average daily net assets up to
$500 million; eighteen and one-half one-hundredths of one percent (0.185%) of a
Fund's average daily net assets in excess of $500 million up to $1 billion; and
seventeen and one-half one-hundredths of one percent (0.175%) of a Fund's
average daily net assets in excess of $1 billion, or (b) such fee as may from
time to time be agreed upon by the Eureka Funds and the Administrator. A fee
agreed to from time to time by the Eureka Funds and the Administrator may be
significantly lower than the fee calculated at the annual rate and the effect of
such lower fee would be to lower a Fund's expenses and increase the net income
of the Fund during the period when such lower fee is in effect.

         The Administration Agreement will continue until May 31, 2000.
Thereafter, the Administration Agreement shall be renewed automatically for
successive two year terms, unless written notice not to renew is given by the
non-renewing party to the other party at least 60 days prior to the expiration
of the then-current term. The Administration Agreement is terminable with
respect to a particular Fund only upon mutual agreement of the parties to the
Administration Agreement and for cause (as defined in the Administration
Agreement) by the party alleging cause, on not less than 60 days notice by the
Eureka Funds' Board of Trustees or by the Administrator.

         The Administration Agreement provides that the Administrator shall not
be liable for any loss suffered by the Eureka Funds in connection with the
matters to which the Administration Agreement relates, except a loss, action or
error resulting from willful


                                      B-46
<PAGE>   102

misfeasance, bad faith, or negligence in the performance of its duties, or by
reason of reckless disregard by the Administrator of its obligations and duties
thereunder.

         For administration services for the fiscal year ended September 30,
1999, the Administrator received the following amounts after voluntary fee
reductions: 0.10% of the average daily net assets of the Prime Money Market
Fund, 0.16% of the average daily net assets of the U.S. Treasury Obligations
Fund, 0.20% of the average daily net assets of the Investment Grade Bond Fund,
0.20% of the average daily net assets of the Global Asset Allocation Fund, and
0.20% of the average daily net assets of the Equity Fund.

BISYS Fund Services received the following fees for administration services:

DISTRIBUTOR

         BISYS Fund Services serves as distributor to each Fund pursuant to a
Distribution Agreement dated October 21, 1997. The Distribution Agreement will
continue in effect for one-year periods if such continuance is approved at least
annually (i) by the Board of Trustees or by the vote of a majority of the
outstanding Shares of the Funds or Fund subject to such Distribution Agreement,
and (ii) by the vote of a majority of the Trustees who are not parties to such
Distribution Agreement or interested persons (as defined in the 1940 Act) of any
party to such Distribution Agreement, cast in person at a meeting called for the
purpose of voting on such approval. The Distribution Agreement may be terminated
in the event of any assignment, as defined in the 1940 Act.

         BISYS Fund Services is entitled to a fee of 0.25% of the average daily
net assets of Class A Shares of each Fund payable under the Fund's Distribution
Plan, for its services as Distributor.

         The Distribution Plan was initially approved on October 21, 1997 by the
Board of Trustees, including a majority of the trustees who are not interested
persons of the Fund (as defined in the 1940 Act) and who have no direct or
indirect financial interest in the Distribution Plan (the "Independent
Trustees"). The Distribution Plan provides for fees only upon the Class A Shares
of each Fund.

         In accordance with Rule 12b-1 under the 1940 Act, the Distribution Plan
may be terminated with respect to any Fund by a vote of a majority of the
Independent Trustees, or by a vote of a majority of the outstanding Class A
Shares of that Fund. The Distribution Plan may be amended by vote of the Board
of Trustees, including a majority of the Independent Trustees, cast in person at
a meeting called for such purpose, except that any change in the Distribution
Plan that would materially increase the distribution fee with respect to a Fund
requires the approval of the holders of that Fund's Class A Shares. The Board of
Trustees will review on a quarterly and annual basis written reports of the
amounts received and expended under the Distribution Plan (including amounts
expended by the Distributor to Participating Organizations pursuant to the
Servicing Agreements entered into under the Distribution Plan) indicating the
purposes for which such expenditures were made.

SERVICE PLAN

         Under the Service Plan, a Fund will pay a monthly service fee to BISYS
Fund Services ("BISYS") as compensation for services in connection with the
Service Plan at an annual rate equal to twenty-five one-hundredths of one
percent (0.25%) of the average daily net assets of Class A Shares of each Fund.
BISYS may periodically waive all or a portion of the fee with respect to a Fund.
BISYS may use the service fee to pay banks, other financial institutions and
intermediaries, broker-dealers, SBCL and SBCL's affiliates and subsidiaries
compensation for services or reimbursement of expenses incurred in connection
with the provision of administrative services or to provide administrative
services to the holders of Class A Shares. All payments by BISYS for services
under the Service Plan will be made pursuant to an agreement (a "Service
Agreement") between BISYS and such bank, financial institution or intermediary,
broker-dealer, or affiliate or subsidiary ("Participating Organization"). A
Service Agreement will relate to the provision of administrative services to the
Participating Organization's customers owning a Fund's Class A Shares. Under the
Service Plan, a Participating Organization may include SBCL or a subsidiary bank
or nonbank affiliates, or the


                                      B-48

subsidiaries or affiliates of those banks. A Service Agreement entered into with
a bank (or any of its subsidiaries or affiliates) will contain a representation
that the bank (or subsidiary or affiliate) believes that it possesses the legal
authority to perform the services contemplated by the Service Agreement without
violation of applicable banking laws (including the Glass-Steagall Act) and
regulations.

DISTRIBUTION PLAN

         The Eureka Funds' Class A Shares are sold on a continuous basis by the
Distributor under a Distribution Agreement. Under the Distribution Plan, a Fund
will pay a monthly distribution fee to the Distributor as compensation for its
services in connection with the Distribution Plan at an annual rate equal to
twenty-five one-hundredths of one percent (0.25%) of the average daily net
assets of Class A Shares of each Fund. The Distributor may periodically waive
all or a portion of the fee with respect to a Fund in order to increase the net
investment income of the Fund available for distribution as dividends. The
Distributor may use the distribution fee to provide distribution assistance with
respect to a Fund's Class A Shares or to provide shareholder services to the
holders of such Shares. The Distributor may also use the distribution fee (i) to
pay financial institutions and intermediaries (such as insurance companies and
investment counselors but not including banks), broker-dealers, and the
Distributor's affiliates and subsidiaries compensation for services or
reimbursement of expenses incurred in connection with distribution assistance or
(ii) to pay banks, other financial institutions and intermediaries,
broker-dealers, and the Distributor's affiliates and subsidiaries compensation
for services or reimbursement of expenses incurred in connection with the
provision of shareholder services. A Servicing Agreement will relate to the
provision of distribution assistance in connection with the distribution of a
Fund's Class A Shares to the Participating Organization's customers on whose
behalf the investment in such Shares is made and/or to the provision of
shareholder services to the Participating Organization's customers owning a
Fund's Class A Shares. Under the Distribution Plan, a Participating Organization
may include SBCL or a subsidiary bank or nonbank affiliates, or the subsidiaries
or affiliates of those banks. A Servicing Agreement entered into with a bank (or
any of its subsidiaries or affiliates) will contain a representation that the
bank (or subsidiary or affiliate) believes that it possesses the legal authority
to perform the services contemplated by the Servicing Agreement without
violation of applicable banking laws (including the Glass-Steagall Act) and
regulations.

         The distribution fee will be payable without regard to whether the
amount of the fee is more or less than the actual expenses incurred in a
particular year by the Distributor in connection with distribution assistance or
shareholder services rendered pursuant to the Servicing Agreements entered into
under the Distribution Plan. If the amount of the distribution fee is greater
than the Distributor's actual expenses incurred in a particular year (and the
Distributor does not waive that portion of the distribution fee), the
Distributor will realize a profit in that year from the distribution fee. If the
amount of the distribution fee is less than the Distributor's actual expenses
incurred in a particular year, the Distributor will realize a loss in that year
under the Distribution Plan and will not recover from a Fund the


                                      B-49
<PAGE>   105
excess of expenses for the year over the distribution fee, unless actual
expenses incurred in a later year in which the Distribution Plan remains in
effect were less than the distribution fee paid in that later year.

         The Distribution Plan also contains a so-called "defensive" provision
applicable to all classes of Shares. Under this defensive provision to the
extent that any payment made to the Administrator, including payment of
administration fees, should be deemed to be indirect financing of any activity
primarily intended to result in the sale of Shares issued by the Eureka Funds
within the context of Rule 12b-1 under the 1940 Act, such payment shall be
deemed to be authorized by the Distribution Plan.


EXPENSES

         SBCL and the Administrator each bear all expenses in connection with
the performance of their services as investment adviser and administrator,
respectively, other than the cost of securities (including brokerage
commissions, if any) purchased for a Fund. The Eureka Funds is responsible for
all of its expenses and liabilities. As a general matter, expenses are allocated
to the Class A Shares and Trust Shares of a Fund on the basis of the relative
net asset value of each class. At present, the only expenses that will be borne
solely by Class A Shares, other than in accordance with the relative net asset
value of the class, are expenses under the Eureka Funds' Distribution and
Shareholder Services Plan ("Distribution Plan") and a Service Plan which relate
only to the Class A Shares.

         The organizational expenses of each Fund have been capitalized and are
being amortized in the first five years of each Fund's operations. Such
amortization will reduce the amount of income available for payment as
dividends. CUSTODIAN

         The Bank of New York serves as the Eureka Funds' custodian.

TRANSFER AGENT AND FUND ACCOUNTING SERVICES

         Under the Transfer Agency Agreement, BISYS Fund Services, Inc., the
Transfer Agent, receives a fee from each Fund at the annual rate of $15,000 in
addition to various annual per account fees.

         BISYS Fund Services, Inc. also provides fund accounting services to
each of the Funds pursuant to a Fund Accounting Agreement with the Eureka Funds.
Under the Fund Accounting Agreement, BISYS Fund Services, Inc. receives a fee
from each Fund at the annual rate of 0.03% of such Fund's average daily net
assets, subject to a minimum annual fee.

YIELDS OF THE MONEY MARKET FUNDS

         From time to time, a Money Market Fund's annualized "yield" and
"effective yield" and total return may be presented in advertisements, sales
literature and shareholder reports. The "yield" of a Money Market Fund is based
upon the income earned by the Fund over a seven-day period and then annualized,
i.e. the income earned in the period is assumed to be earned every seven days
over a 52-week period and is stated as a percentage of the investment. The
"effective yield" of a Money Market Fund is calculated similarly but when
annualized, the income earned by the investment is assumed to be reinvested in
Shares of the Eureka Funds and thus compounded in the course of a 52-week
period. The effective yield will be higher than the yield because of the
compounding effect of the assumed reinvestment.

         The "yield" of each Money Market Fund for a seven-day period (a "base
period") will be computed by determining the "net change in value" (calculated
as set forth below) of a hypothetical account having a balance of one share at
the beginning of the period, dividing the net change in account value by the
value of the account at the beginning of the base period to obtain the base
period return, and multiplying the base period return by 365/7 with the
resulting yield figure carried to the nearest hundredth of one percent. Net
changes in value of a hypothetical account will include the value of additional
shares purchased with dividends from the original share and dividends declared
on both the original share and any such additional shares, but will not include
realized gains or losses or unrealized appreciation or depreciation on portfolio
investments. Yield may also be calculated on a compound basis (the "effective
yield") which assumes that net income is reinvested in Fund shares at the same
rate as net income is earned for the base period.

         The yield and effective yield of each Money Market Fund will vary in
response to fluctuations in interest rates and in the expenses of each Fund. For
comparative purposes the current and effective yields should be compared to
current and effective yields offered by


                                      B-51

<PAGE>   107



competing financial institutions for that base period only and calculated by the
methods described above.

         For the seven-day and thirty-day periods ended September 30, 1999, the
yield and effective yield, of the Trust Shares and Class A Shares of the U.S.
Treasury Obligations Fund, and the Prime Money Market Fund calculated as
described above was as follows:

YIELDS OF THE VARIABLE NAV FUNDS

         The yields of the Variable NAV Funds will be computed by annualizing
net investment income per share for a recent 30-day period and dividing that
amount by the maximum offering price per share (reduced by any undeclared earned
income expected to be paid shortly as a dividend) on the last trading day of
that period, according to the following formula:

                                            a-b
                        30-Day Yield = 2[( ----- +1) (to the sixth power) -1]
                                            cd

         In the above formula, "a" represents dividends and interest earned by a
particular class during the 30-day base period; "b" represents expenses accrued
to a particular class for the 30- day base period (net of reimbursements); "c"
represents the average daily number of shares of a particular class outstanding
during the 30-day base period that were entitled to receive dividends; and "d"
represents the maximum offering price per share of a particular class on the
last day of the 30-day base period.

         Net investment income will reflect amortization of any market value
premium or discount of fixed income securities (except for obligations backed by
mortgages or other assets) and may include recognition of a pro rata portion of
the stated dividend rate of dividend paying portfolio securities. The yield of
each of the Variable NAV Funds will vary from time to time depending upon market
conditions, the composition of the Fund's portfolio and operating expenses of
the Eureka Funds allocated to each Fund. These factors and possible differences
in the methods used in calculating yield should be considered when comparing a
Fund's yield to


                                      B-52

<PAGE>   108



yields published for other investment companies and other investment vehicles.
Yield should also be considered relative to changes in the value of the Fund's
shares and to the relative risks associated with the investment objectives and
policies of each Fund.

         Investors in the Variable NAV Funds are specifically advised that share
prices, expressed as the net asset values per share, will vary just as yields
will vary.

         For the 30-day period ending September 30, 1999, the yield of the Trust
Shares and Class A Shares of the Investment Grade Bond Fund, the Global Asset
Allocation Fund, and the Equity Fund, calculated as described above was as
follows:

Investment Grade Bond Fund                Class A                         5.67%
Global Asset Allocation Fund              Class A                         6.33%
Equity Fund                               Class A                         0.13%


CALCULATION OF TOTAL RETURN

         Total Return is a measure of the change in value of an investment in a
Fund over the period covered, assuming the investor paid the current maximum
applicable sales charge on the investment and that any dividends or capital
gains distributions were reinvested in the Fund immediately rather than paid to
the investor in cash.

         Total return is calculated for the past year and the period since the
establishment of each Fund. Average annual total return is measured by comparing
the value of an investment in a Fund at the beginning of the relevant period to
the redemption value of the investment at the end of the period (assuming
immediate reinvestment of any dividends or capital gains distributions) and
annualizing the result. Aggregate total return is calculated similarly to
average annual total return except that the return figure is aggregated over the
relevant period instead of annualized. The formula for calculating Total Return
includes four steps: (1) adding to the total number of shares purchased by a
hypothetical $1,000 investment in the Fund all additional shares which would
have been purchased if all dividends and distributions paid or distributed
during the period had been immediately reinvested; (2) calculating the value of
the hypothetical initial investment of $1,000 as of the end of the period by
multiplying the total number of shares owned at the end of the period by the net
asset value per share on the last trading day of the period; (3) assuming
redemption at the end of the period; and (4) dividing this account value for the
hypothetical investor by the initial $1,000 investment


                                      B-53

<PAGE>   109



and annualizing the result for periods of less than one year.

         At any time in the future, yields and total return may be higher or
lower than past yields, there can be no assurance that any historical results
will continue.

For the period since inception through September 30, 1999, aggregate total
return was as follows:

PERFORMANCE COMPARISONS

         YIELD AND TOTAL RETURN. From time to time, performance information for
the Funds showing their total return and/or yield may be included in
advertisements. Performance figures are based on historical earnings and are not
intended to indicate future performance.

         From time to time, the Eureka Funds may include the following types of
information in advertisements, supplemental sales literature and reports to
present or prospective shareholders: (1) discussions of general economic or
financial principals (such as the effects of inflation, the power of compounding
and the benefits of dollar-cost averaging); (2) discussions of general economic
trends; (3) presentations of statistical data to supplement such discussions;
(4) descriptions of past or anticipated portfolio holdings for one or more of
the Funds within

the Eureka Funds, (5) descriptions of investment strategies for one or more of
such Funds; (6) descriptions or comparisons of various savings and investment
products (including, but not limited to, insured bank products, annuities,
qualified retirement plans and individual stocks and bonds), which may or may
not include the Funds; (7) comparisons of investment products (including the
Funds) with relevant market indices, industry indices, blended indices
(including indices created by the Adviser combining two or more indices), or
other appropriate benchmarks; (8) discussions of fund rankings or ratings by
recognized rating organizations; and (9) testimonials describing the experience
of persons that have invested in one or more of the Funds. The Funds may also
include in these communications calculations, such as hypothetical compounding
examples, that describe hypothetical investment results, such performance
examples will be based on an express set of assumptions and are not indicative
of performance of any of the Funds.

         Total return and/or yield may also be used to compare the performance
of the Funds against certain widely acknowledged standards or indices for stock
and bond market performance. The Standard & Poor's 500 Composite Stock Price
Index (the "S&P 500 Index") is a market value-weighted and unmanaged index
showing the changes in the aggregate market value of 500 stocks relative to the
base period 1941-43. The S&P 500 Index is composed almost entirely of common
stocks of companies listed on the NYSE, although the common stocks of a few
companies listed on the American Stock Exchange or traded over-the-counter are
included. The 500 companies represented include 400 industrial, 60
transportation and 40 financial services concerns. The S&P 500 represents about
80% of the market value of all issues traded on the NYSE.

         The Morgan Stanley Capital International Europe, Australasia and the
Far East Index ("EAFE") is an index composed of a sample of companies
representative of the market structure of twenty European and Pacific Basin
countries. The Index represents the evolution of an unmanaged portfolio
consisting of all domestically listed stocks.

         The Lehman Brothers Aggregate Bond Index ("Aggregate Bond Index") is a
measure of the market value of all public obligations of the U.S. Treasury; all
publicly issued debt of all agencies of the U.S. government; all quasi-federal
corporations; all corporate debt guaranteed by the U.S. government; and mortgage
backed securities. Corporate issues must have amounts outstanding in excess of
$1 million, have at least one year to maturity and be rated investment grade by
a NRSRO. Flower bonds and foreign targeted issues are also included in the
Aggregate Bond Index.

         Current yields or performance will fluctuate from time to time and are
not necessarily representative of future results. Accordingly, a Fund's yield or
performance may not provide for comparison with bank deposits or other
investments that pay a fixed return for a stated period of time. Yield and
performance are functions of quality, composition, and maturity, as well as
expenses allocated to the Fund. Fees imposed upon customer accounts by SBCL or
its affiliated or correspondent banks for cash management services will reduce a
Fund's effective


                                      B-56

yield to Customers.

         The Investment Grade Bond Fund, the Global Asset Allocation Fund and
the Equity Fund may also calculate a distribution rate. Distribution rates will
be computed by dividing the distribution per Share of a class made by a Fund
over a twelve-month period by the maximum offering price per Share. The
distribution rate includes both income and capital gain dividends and does not
reflect unrealized gains or losses. The calculation of income in the
distribution rate includes both income and capital gain dividends and does not
reflect unrealized gains or losses, although a Fund may also present a
distribution rate excluding the effect of capital gains. The distribution rate
differs from the yield, because it includes capital items which are often
non-recurring in nature, and may include returns of principal, whereas yield
does not include such items. The Funds do not intend to publish distribution
rates in Fund advertisements but may publish such rates in supplemental sales
literature.

         Yield, effective yield, total return and distribution rate will be
calculated separately for each Class of Shares. Because Trust Shares are not
subject to Distribution Plan fees or Service Plan fees, the yield and total
return for Trust Shares will be higher than that of the Class A Shares for the
same period.

         Investors may also judge the performance of a Fund by comparing its
performance to the performance of other mutual funds with comparable investment
objectives and policies through various mutual fund or market indices and data
such as that provided by Lipper Inc., IBC/Donoghue's MONEY FUND REPORT and
Ibbotson Associates, Inc. References may also be made to indices or data
published in Money Magazine, Forbes, Barron's, The Wall Street Journal, The New
York Times, Business Week, American Banker, Fortune, Institutional Investor,
Ibbotson Associates, Inc., Morningstar, Inc., CDA/Weisenberger, Pension and
Investments, U.S.A. Today and local newspapers. In addition to performance
information, general information about the Funds that appears in a publication
such as those mentioned above may be included in advertisements and in reports
to Shareholders.

         Information about the performance of a Fund is based on a Fund's record
up to a certain date and is not intended to indicate future performance. Yields
and total returns of a Fund will fluctuate. Any fees charged by the
Participating Organizations to their customers in connection with investment in
a Fund are not reflected in the Eureka Funds' performance information.

         Further information about the performance of a Fund is contained in
that Fund's annual report to Shareholders, which may be obtained without charge
by contacting the Eureka Funds at P.O. Box 182792, Columbus, Ohio 43218-2792.

<PAGE>   113



         The Eureka Funds organized as a Massachusetts business trust by the
Agreement and Declaration of Trust, dated April 7, 1997, under the name "Sanwa
Fund." A copy of the Eureka Funds' Amended and Restated Agreement and
Declaration of Trust, (the "Declaration of Trust") is on file with the Secretary
of State of The Commonwealth of Massachusetts. The Declaration of Trust
authorizes the Board of Trustees to issue an unlimited number of Shares, which
are units of beneficial interest. The Eureka Funds presently have five series of
Shares offered to the public. The Declaration of Trust authorizes the Board of
Trustees to divide or redivide any unissued Shares of the Eureka Funds into one
or more additional series.

         Shares have no subscription or preemptive rights and only such
conversion or exchange rights as the Board of Trustees may grant in its
discretion. When issued for payment as described in the Prospectuses and this
Statement of Additional Information, the Shares will be fully paid and
non-assessable. In the event of a liquidation or dissolution of the Eureka
Funds, Shareholders of a Fund are entitled to receive the assets available for
distribution belonging to that Fund, and a proportionate distribution, based
upon the relative asset values of the respective Funds, of any general assets
not belonging to any particular Fund which are available for distribution.

         Shares of the Eureka Funds are entitled to one vote per share (with
proportional voting for fractional shares) on such matters as shareholders are
entitled to vote. Shareholders vote in the aggregate and not by series or class
on all matters except (i) when required by the 1940 Act, shares shall be voted
by individual series, (ii) when the Trustees have determined that the matter
affects only the interests of a particular series or class, then only
Shareholders of such series or class shall be entitled to vote thereon, and
(iii) only the holders of Class A Shares will be entitled to vote on matters
submitted to Shareholder vote with regard to the Distribution Plan applicable to
Class A. There will normally be no meetings of Shareholders for the purposes of
electing Trustees unless and until such time as less than a majority of the
Trustees have been elected by the Shareholders, at which time the Trustees then
in office will call a Shareholders' meeting for the election of Trustees. In
addition, Trustees may be removed from office by a written consent signed by the
holders of two-thirds of the outstanding shares of the Eureka Funds and filed
with the Eureka Funds' custodian or by vote of the holders of two-thirds of the
outstanding shares of the Eureka Funds at a meeting duly called for the purpose,
which meeting shall be held upon the written request of the holders of not less
than 10% of the outstanding shares of any Fund. Except as set forth above, the
Trustees shall continue to hold office and may appoint their successors.

SHAREHOLDER AND TRUSTEE LIABILITY

         Under Massachusetts law, Shareholders could, under certain
circumstances, be held personally liable for the obligations of the Eureka
Funds. However, the Declaration of Trust disclaims Shareholder liability for
acts or obligations of the Eureka Funds and requires that notice of such
disclaimer be given in every agreement, obligation or instrument entered into or
executed by the Eureka Funds or the Trustees. The Declaration of Trust provides
for


                                      B-58

<PAGE>   114



indemnification out of a Fund's property for all loss and expense of any
Shareholder of such Fund held liable on account of being or having been a
Shareholder. Thus, the risk of a Shareholder incurring financial loss on account
of Shareholder liability is limited to circumstances in which a Fund would be
unable to meet its obligations.

         The Agreement and Declaration of Trust states further that no Trustee,
officer or agent of the Eureka Funds shall be personally liable in connection
with the administration or preservation of the assets of the Eureka Funds or the
conduct of the Eureka Funds' business; nor shall any Trustee, officer, or agent
be personally liable to any person for any action or failure to act except for
his own bad faith, willful misfeasance, gross negligence, or reckless disregard
of his duties. The Agreement and Declaration of Trust also provides that all
persons having any claim against the Trustees or the Eureka Funds shall look
solely to the assets of the Eureka Funds for payment.

MISCELLANEOUS

         The Eureka Funds may include information in its Annual Reports and
Semi-Annual Reports to Shareholders that (1) describes general economic trends,
(2) describes general trends within the financial services industry or the
mutual fund industry, (3) describes past or anticipated portfolio holdings for
one or more of the Funds within the Eureka Funds, or (4) describes investment
management strategies for such Funds. Such information is provided to inform
Shareholders of the activities of the Eureka Funds for the most recent fiscal
year or half-year and to provide the views of the SBCL and/or Eureka Funds
officers regarding expected trends and strategies.

         The organizational expenses of the Eureka Funds have been allocated to
each Fund and are being amortized over a period of five years from the
commencement of the public offering of Shares of the Eureka Funds. In the event
any of the initial Shares of the Eureka Funds are redeemed during the
amortization period by any holder thereof, the redemption proceeds will be
reduced by a pro rata portion of any unamortized organization expenses in the
same proportion as the number of initial Shares being redeemed bears to the
total number of initial Shares outstanding at the time of redemption. Investors
purchasing Shares of the Eureka Funds subsequent to the date of the Prospectuses
and this Statement of Additional Information bear such expenses only as they are
amortized against a Fund's investment income.

         The Eureka Funds are registered with the Securities and Exchange
Commission as a management investment company. Such registration does not
involve supervision by the Securities and Exchange Commission of the management
or policies of the Eureka Funds.

         As of January 14, 2000, the trustees and officers of the Trust, as a
group, owned less than 1% of the Trust Shares and of the Class A Shares of any
of the Eureka Funds.

                                    APPENDIX

The NRSROs utilized by SBCL include Moody's Investors Service, Inc. ("Moody's"),
Standard & Poor's Corporation ("S&P"), Duff & Phelps Credit Rating Co. ("Duff"),
Fitch IBCA ("Fitch"), and Thomson BankWatch, Inc. ("Thomson"). Set forth below
is a description of the relevant ratings of each such NRSRO.

LONG-TERM DEBT RATINGS (may be assigned, for example, to corporate and municipal
bonds)

Description of the five highest long-term debt ratings by Moody's (Moody's
applies numerical modifiers (1, 2, and 3) in each rating category to indicate
the security's ranking within the category):

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

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

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

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

<PAGE>   119



                  characterizes bonds in this class.

Description of the five highest long-term debt ratings by S&P (S&P may apply a
plus (+) or minus (-) to a particular rating classification to show relative
standing within that classification):

         AAA      Debt rated AAA has the highest rating assigned by S&P. The
                  obligor's capacity to meet its financial commitment on the
                  obligation is extremely strong.

         AA       Debt rated AA differs from the highest rated obligations only
                  in small degree. The obligor's capacity to meet its financial
                  commitment on the obligation is very strong.

         A        Debt rated A is somewhat more susceptible to the adverse
                  effects of changes in circumstances and economic conditions
                  than obligations in higher rated categories. However, the
                  obligor's capacity to meet its financial commitment on the
                  obligation is still strong.

         BBB      Debt rated BBB exhibits adequate protection parameters.
                  However, adverse economic conditions or changing circumstances
                  are more likely to lead to a weakened capacity of the obligor
                  to meet its financial commitment on the obligation.

         BB       Debt rated BB is regarded as having significant speculative
                  characteristics although it is less vulnerable to nonpayment
                  than other speculative issues. However, it faces major ongoing
                  uncertainties or exposure to adverse business, financial or
                  economic conditions which could lead to the obligor's
                  inadequate capacity to meet its financial commitment on the
                  obligation.

Description of the three highest long-term debt ratings by Duff:

         AAA      Highest credit quality. The risk factors are negligible, being
                  only slightly more than for risk-free U.S. Treasury debt.

         AA+      High credit quality.  Protection factors are strong.
         AA       Risk is modest but may vary slightly from time to time
         AA-      because of economic conditions.

         A+       Protection factors are average but adequate. However,
         A        risk factors are more variable and greater in periods
         A-       of economic stress.

are used with a rating symbol to indicate the relative position of the credit
within the rating category):

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

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

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

Fitch's description of its three highest long-term debt ratings:

         AAA      Obligations which have the highest rating. Capacity for timely
                  repayment of principal and interest is extremely strong.

         AA       Obligations for which capacity for timely repayment of
                  principal and interest is very strong. The risk attached to
                  these obligations differs only slightly from the highest rated
                  debt.

         A        Obligations for which capacity for timely repayment of
                  principal and interest is strong. However, adverse changes in
                  business, economic or financial conditions are more likely to
                  affect the capacity for timely repayment than for obligations
                  in higher rated categories.

SHORT-TERM DEBT RATINGS (may be assigned, for example, to commercial paper,
master demand notes, bank instruments, and letters of credit)

Moody's description of its three highest short-term debt ratings:

         Prime-1         Issuers rated Prime-1 (or supporting institutions) have
                         a superior ability for repayment of senior short-term
                         debt obligations. Prime-1 repayment ability will often
                         be evidenced by many of the following characteristics:

                                  - Leading market positions in well-established
                                    industries.
                                  - High rates of return on funds employed.

                                  - Conservative capitalization structure 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.

         Prime-2         Issuers rated Prime-2 (or supporting institutions) have
                         a strong ability for repayment of senior short-term
                         debt 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, may be more subject to variation. Capitalization
                         characteristics, while still appropriate, may be more
                         affected by external conditions. Ample alternate
                         liquidity is maintained.

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

S&P's description of its three highest short-term debt ratings:

         A-1      Highest category. The obligor's capacity to meet its financial
                  commitments is strong. Within this category, certain
                  obligations are designated with a plus sign (+). This
                  indicates that the obligor's capacity to meet its financial
                  commitments is extremely strong.

         A-2      Obligations assigned this rating are somewhat more susceptible
                  to the adverse effects of changes in circumstances and
                  economic conditions than obligations in higher rating
                  categories. However, the obligor's capacity to meet its
                  financial commitment on the obligation is satisfactory.

         A-3      Obligations assigned this rating exhibit adequate protection
                  parameters. However, adverse economic conditions or changing
                  circumstances are more likely to lead to a weakened capacity
                  of the obligor to meet its financial commitment on the
                  obligation.

Duff's description of its five highest short-term debt ratings. Duff
incorporates gradations of "1+" (one plus) and "1-" (one minus) to assist
investors in recognizing quality differences within the highest rating category:

<PAGE>   122



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

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

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

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

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

Fitch's description of its four highest short-term debt ratings:

         F1       Obligations assigned this rating have the highest capacity for
                  timely payment.

         F2       Obligations supported by a strong capacity for timely
                  repayment. However, the relative degree of risk is slightly
                  higher than for issues classified as "F1" and capacity for
                  timely repayment may be susceptible to adverse changes in
                  business, economic, or financial conditions.

         F3       Obligations supported by an adequate capacity for timely
                  payment. Such capacity is more susceptible to adverse changes
                  in business, economic, or financial conditions than for
                  obligations in higher rated categories.
 .
         B        Obligations for which the capacity for timely repayment is
                  uncertain relative. The capacity for timely repayment is
                  susceptible to adverse changes in business, economic, or
                  financial conditions.


SHORT-TERM LOAN/MUNICIPAL NOTE RATINGS

Moody's description of its two highest short-term loan/municipal note ratings:



                                      B-67

<PAGE>   123



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

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

S&P's description of its two highest municipal note ratings:

           SP-1          Strong capacity to pay principal and interest. An issue
                         determined to possess a very strong capacity to pay
                         debt service is given a plus (+) designation.

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

SHORT-TERM DEBT RATINGS

Thomson BankWatch, Inc. ("TBW") ratings are based upon a qualitative and
quantitative analysis of all segments of the organization including, where
applicable, holding company and operating subsidiaries.

The TBW Short-Term Debt Ratings apply only to specific debt instruments with
original maturities of one year or less. TBW ratings represent an assessment of
the likelihood of an untimely payment of principal and interest. Important
factors that may influence this assessment are the overall financial health of
the particular company, and the probability that the government will come to the
aid of a troubled institution in order to avoid a default or failure.

The TBW Short-Term Ratings represent an assessment of the likelihood of an
untimely payment of principal or interest.

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

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

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

<PAGE>   124


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