TOTAL RETURN BOND FUND

INVESTMENT OBJECTIVE, STRATEGIES AND RISKS


Objective:                              The TOTAL RETURN BOND FUND seeks to
                                        maximize long-term total return.

Principal Investment                    The Fund invests in a diversified
Strategies:                             portfolio of fixed-income securities of
                                        varying maturities issued by domestic
                                        and foreign corporations and governments
                                        (and their agencies and
                                        instrumentalities) with a portfolio
                                        duration of two to eight. The meaning of
                                        "duration" is explained below under
                                        "Investment Policies of the Funds." The
                                        dollar-weighted average maturity of the
                                        Fund's portfolio is expected to range
                                        from two to fifteen years. The Fund's
                                        portfolio may include bonds, notes,
                                        mortgage-related and asset-backed
                                        securities and money-market securities.
                                        These investments may have interest
                                        rates that are fixed, variable or
                                        floating.

                                        The Adviser will concentrate the Fund's
                                        portfolio holdings in areas of the bond
                                        market (based on quality, sector, coupon
                                        or maturity) that the Adviser believes
                                        to be relatively undervalued.

                                        Under normal circumstances, the Fund
                                        will invest at least 80% of its net
                                        assets in investment grade securities.
                                        These are debt securities rated at least
                                        Baa3 by Moody's Investor's Service
                                        ("Moody's") or BBB- by Standard & Poor's
                                        Rating Group ("S&P"), Fitch Investors
                                        Services, Inc. ("Fitch") or Duff &
                                        Phelps Credit Rating Co. ("Duff &
                                        Phelps"), or A-2 by S&P, P-2 by Moody's,
                                        F-2 by Fitch or D-2 by Duff & Phelps for
                                        short-term debt obligations, or
                                        securities of comparable quality to
                                        investment grade securities as
                                        determined by the Adviser in the case of
                                        unrated securities. Up to 20% of the
                                        Fund's net assets may be invested in
                                        securities rated below investment grade
                                        but rated B or higher by one of the
                                        nationally recognized statistical rating
                                        organizations or, if unrated, of
                                        comparable quality in the opinion of the
                                        Adviser.

                                        The Fund may invest a portion of its
                                        assets in foreign securities
                                        (denominated in U.S. dollars or foreign
                                        currencies), including emerging market
                                        foreign securities.

Principal Investment Risks:             Because the values of the Fund's
                                        investments will change with market
                                        conditions, so will the value of your
                                        investment in the Fund. You could lose
                                        money on your investment in the Fund or
                                        the Fund could underperform other
                                        investments. This Fund has the potential
                                        for greater return and loss than a
                                        shorter duration fund like the LOW
                                        DURATION BOND FUND.

                                        The values of the Fund's investments
                                        change in response to movements in
                                        interest rates. If rates rise, the
                                        values of debt securities generally
                                        fall. The longer the average duration of
                                        the Fund's investment portfolio, the
                                        greater the change in value. The values
                                        of any of the Fund's investments may
                                        also decline in response to events
                                        affecting the issuer or its credit
                                        rating. The lower rated debt securities
                                        in which the Fund may invest are
                                        considered speculative and are subject
                                        to greater volatility and risk of loss
                                        than investment grade securities,
                                        particularly in deteriorating economic
                                        conditions.

                                        The value of the Fund's investments in
                                        foreign securities also depends on
                                        changing currency values, different
                                        political and economic environments and
                                        other overall economic conditions in the
                                        countries where the Fund invests.
                                        Emerging market debt securities tend to
                                        be of lower credit quality and subject
                                        to greater risk of default than higher
                                        rated securities from more developed
                                        markets.

PERFORMANCE

         The charts on this page show how the Fund has performed and provide
some indication of the risks of investing in the Fund by showing the performance
of the Fund's shares during its first complete calendar year of operations. The
bar chart shows changes in the year-to-year performance of the Fund. The table
below it compares the performance of the Fund over time to the Lehman Brothers
Aggregate Bond Index, an unmanaged index of [all investment grade bonds with a
total amount outstanding in excess of $25 million that have at least one year to
maturity.]

         Both charts assume reinvestment of dividends and distributions. Of

LOW DURATION BOND FUND

INVESTMENT OBJECTIVE, STRATEGIES AND RISKS

Objective:                          The LOW DURATION BOND FUND seeks to maximize
                                    current income, consistent with preservation
                                    of capital.


Principal Investment                The Fund invests in a diversified portfolio
Strategies:                         of fixed- income securities of varying
                                    maturities issued by domestic and foreign
                                    corporations and governments (and their
                                    agencies and instrumentalities) with a
                                    portfolio duration of up to three. The
                                    meaning of "duration" is explained below
                                    under "Investment Policies of the Funds."
                                    The dollar-weighted average maturity of the
                                    Fund's portfolio is expected to range from
                                    one to five years. The Fund's portfolio may
                                    include bonds, notes, mortgage-related and
                                    asset-backed securities and money-market
                                    securities. These investments may have
                                    interest rates that are fixed, variable or
                                    floating.

                                    Under normal circumstances, the Fund will
                                    invest at least 70% of its net assets in
                                    highly rated securities. These are debt
                                    securities rated at least A by Moody's, S&P,
                                    Fitch or Duff & Phelps, or A-2 by S&P, P-2
                                    by Moody's, F-2 by Fitch or D-2 by Duff &
                                    Phelps for short-term debt obligations, or
                                    securities of comparable quality to highly
                                    rated securities as determined by the
                                    Adviser in the case of unrated securities.
                                    Up to 20% of the Fund's net assets may be
                                    invested in securities rated below highly
                                    rated securities but rated at least
                                    investment grade by one of the nationally
                                    recognized statistical rating organizations
                                    or, if unrated, of comparable quality in the
                                    opinion of the Adviser. Up to 10% of the
                                    Fund's net assets may be invested in
                                    securities rated below investment grade but
                                    rated B or higher by one of the nationally
                                    recognized statistical rating organizations
                                    or, if unrated, of comparable quality in the
                                    opinion of the Adviser.

                                    The Fund may invest a portion of its assets
                                    in foreign securities (denominated in U.S.
                                    dollars or foreign currencies) including
                                    emerging market foreign securities.

Principal Investment Risks:         Because the values of the Fund's investments
                                    will change with market conditions, so will
                                    the value of your investment in the Fund.
                                    You could lose money on your investment in
                                    the Fund or the Fund could underperform
                                    other investments. The Adviser expects that
                                    this Fund will typically display lower
                                    changes in value, return and risk of loss
                                    than a longer-duration fixed-income fund
                                    such as the TOTAL RETURN BOND FUND.

<PAGE>   12

                                    The values of the Fund's investments
                                    fluctuate in response to movements in
                                    interest rates. If rates rise, the values of
                                    debt securities generally fall. The longer
                                    the average duration of the Fund's
                                    investment portfolio, the greater the change
                                    in value. The values of any of the Fund's
                                    investments may also decline in response to
                                    events affecting the issuer or its credit
                                    rating. The lower rated debt securities in
                                    which the Fund may invest are considered
                                    speculative and are subject to greater
                                    volatility and risk of loss than investment
                                    grade securities, particularly in
                                    deteriorating economic conditions.

                                    The value of the Fund's investments in
                                    foreign securities also depends on changing
                                    currency values, different political and
                                    economic environments and other overall
                                    economic conditions in the countries where
                                    the Fund invests. Emerging market debt
                                    securities tend to be of lower credit
                                    quality and subject to greater risk of
                                    default than higher rated securities from
                                    more developed markets.

SHORT-TERM INVESTMENT FUND

         SHARES OF THE SHORT-TERM INVESTMENT FUND ARE NOT CURRENTLY AVAILABLE
FOR PURCHASE.

INVESTMENT OBJECTIVE, STRATEGIES AND RISKS


Objective:                              The SHORT-TERM INVESTMENT FUND seeks to
                                        maximize current income, consistent with
                                        preservation of capital.

Principal Investment                    The Fund invests in a portfolio of
Strategies:                             fixed-income securities of varying
                                        maturities issued by domestic and
                                        foreign corporations and governments
                                        (and their agencies and
                                        instrumentalities) with a portfolio
                                        duration of up to one. The meaning of
                                        "duration" is explained below under
                                        "Investment Policies of the Funds." The
                                        Fund's dollar-weighted average portfolio
                                        maturity will normally exceed one year.
                                        The Fund's portfolio may include bonds,
                                        notes, mortgage-related and asset-backed
                                        securities and money-market securities.
                                        These investments may have interest
                                        rates that are fixed, variable or
                                        floating.

                                        Under normal circumstances, the Fund
                                        will invest at least 70% of its net
                                        assets in highly rated securities. These
                                        are debt securities rated at least A by
                                        Moody's, S&P, Fitch or Duff & Phelps, or
                                        A-2 by S&P, P-2 by Moody's, F-2 by Fitch
                                        or D-2 by Duff & Phelps for short-term
                                        debt obligations, or securities of
                                        comparable quality to highly rated
                                        securities as determined by the Adviser
                                        in the case of unrated securities. Up to
                                        20% of the Fund's net assets may be
                                        invested in securities rated below
                                        highly rated securities but rated at
                                        least investment grade by one of the
                                        nationally recognized statistical rating
                                        organizations or, if unrated, of
                                        comparable quality in the opinion of the
                                        Adviser. Up to 10% of the Fund's net
                                        assets may be invested in securities
                                        rated below investment grade but rated B
                                        or higher by one of the nationally
                                        recognized statistical rating
                                        organizations or, if unrated, of
                                        comparable quality in the opinion of the
                                        Adviser. The Fund may invest a portion
                                        of its assets in foreign securities
                                        (denominated in U.S. dollars or foreign
                                        currencies) including emerging market
                                        foreign securities.

Principal Investment Risks:             Because the values of the Fund's
                                        investments will fluctuate with market
                                        conditions, so will the value of your
                                        investment in the Fund. You could lose
                                        money on your investment in the Fund or
                                        the Fund could underperform other
                                        investments. The Adviser expects that
                                        this Fund will typically display
                                        relatively lower changes in value,
                                        return and risk of loss than the longer
                                        duration TOTAL RETURN FUND and LOW
                                        DURATION FUND.

                                        The values of the Fund's investments
                                        fluctuate in response to movements in
                                        interest rates. If rates rise, the
                                        values of debt securities generally
                                        fall. The longer the average maturity of
                                        the Fund's investment portfolio, the
                                        greater the change in value. The values
                                        of any of the Fund's investments may
                                        also decline in response to events
                                        affecting the issuer or its credit
                                        rating. The lower rated debt securities
                                        in which the Fund invests are considered
                                        speculative and are subject to greater
                                        volatility and risk of loss than
                                        investment grade securities,
                                        particularly in deteriorating economic
                                        conditions.

                                        The value of the Fund's investments in
                                        foreign securities also depends on
                                        changing currency values, different
                                        political and economic environments and
                                        other overall economic conditions in the
                                        countries where the Fund invests.
                                        Emerging market debt securities tend to
                                        be of lower credit quality and subject
                                        to greater risk of default than higher
                                        rated securities from more developed
                                        markets.

ALPHATRAK 500 FUND

INVESTMENT OBJECTIVE, STRATEGIES AND RISKS


Objective:                              The ALPHATRAK 500 FUND seeks to achieve
                                        a total return that exceeds the total
                                        return of the S&P 500 Index.

Principal Investment                    The Fund is an enhanced S&P 500 Index
Strategies:                             fund that combines non-leveraged
                                        investments in S&P 500 Index futures
                                        with a fixed income portfolio. The
                                        Adviser will actively manage the
                                        fixed-income portfolio in an effort to
                                        produce an investment return that, when
                                        combined with the Fund's return on the
                                        S&P 500 Index futures, will exceed the
                                        total return of the S&P 500 Index.

                                        Under normal market conditions, the Fund
                                        will invest in S&P 500 Index futures
                                        contracts with a contractual or
                                        "notional" value substantially equal to
                                        the Fund's total assets. The Fund will
                                        need to make margin deposits with
                                        futures commission merchants
                                        (broker-dealers for futures contracts)
                                        with a total value equal to
                                        approximately 4-5% of the notional value
                                        of the futures contracts and invest the
                                        rest of its assets in a diversified
                                        portfolio of fixed-income securities of
                                        varying maturities issued by domestic
                                        and foreign corporations and governments
                                        (and their agencies and
                                        instrumentalities) with a portfolio
                                        duration of up to three. The meaning of
                                        "duration" is explained below under
                                        "Investment Policies of the Funds." The
                                        Fund's dollar-weighted average maturity
                                        is normally expected to exceed three
                                        years. The Fund's portfolio may include
                                        bonds, notes, mortgage-related and
                                        asset-backed securities and money-market
                                        securities. These investments may have
                                        interest rates that are fixed, variable
                                        or floating.

                                        Under normal circumstances, the Fund
                                        will invest at least 85% of its net
                                        assets in debt instruments rated at
                                        least investment grade or debt
                                        securities of comparable quality to
                                        investment grade securities as
                                        determined by the Adviser in the case of
                                        unrated securities. Up to 15% of the
                                        Fund's net assets may be invested in
                                        securities rated below investment grade
                                        but rated B or higher by one of the
                                        nationally recognized statistical rating
                                        organizations or, if unrated, of
                                        comparable quality in the opinion of the
                                        Adviser.

                                        The Fund may invest a portion of its
                                        assets in foreign securities
                                        (denominated in U.S. dollars or foreign
                                        currencies) including emerging market
                                        foreign securities.

                                        The Fund is not designed for investors
                                        that are sensitive to taxable gains.
                                        This Fund will recognize most gains, if
                                        any, in each taxable year and is most
                                        suitable for tax-deferred or non-taxable
                                        investors such as IRAs and employee
                                        benefit plans.

                                        The S&P 500 Index consists of 500 stocks
                                        chosen by Standard & Poor's for market
                                        size, liquidity and industry group
                                        representation. It is a market-value
                                        weighted unmanaged index (stock price
                                        times number of shares outstanding),
                                        with each stock's weight in the S&P 500
                                        Index proportionate to its market value.
                                        The Fund is neither sponsored by, nor
                                        affiliated with, Standard & Poor's.


Principal Investment Risks:             Because the values of the Fund's
                                        investments will change with market
                                        conditions, so will the value of your
                                        investment in the Fund. You could lose
                                        money on your investment in the Fund or
                                        the Fund could underperform other
                                        investments. The Adviser expects that
                                        this Fund will typically experience the
                                        same changes in value and risk of loss
                                        as the general stock market reflected in
                                        the S&P 500 Index.

                                        The ability of the Fund to match or
                                        exceed the performance of the S&P 500
                                        Index will depend on whether the
                                        performance of its fixed-income
                                        portfolio exceeds the costs of investing
                                        in S&P 500 Index futures contracts and
                                        the Fund's other fees and expenses.
                                        Risks inherent in the use of S&P 500
                                        Index futures and other S&P 500 Index
                                        derivatives include dependence on the
                                        Adviser's ability to predict correctly
                                        movements in the direction of securities
                                        prices. In addition, although S&P 500
                                        Index derivatives are used by many
                                        investors, which generally results in a
                                        liquid market for those instruments,
                                        from time to time liquidity may be
                                        limited. Limited liquidity could
                                        adversely affect the Fund and prevent it
                                        from closing an unfavorable position
                                        while remaining obligated to meet
                                        increasing margin requirements. The Fund
                                        could lose the entire amount invested in
                                        these futures. The Fund could also face
                                        potentially unlimited losses from other
                                        types of futures and derivatives.

                                        The values of the Fund's fixed income
                                        investments change in response to
                                        movements in interest rates. If rates
                                        rise, the values of debt securities
                                        generally fall. The longer the average
                                        duration of the Fund's investment
                                        portfolio, the greater the

                                       16
<PAGE>   22


                                        change in value. The values of any of
                                        the Fund's investments in debt
                                        securities may also decline in response
                                        to events affecting the issuer or its
                                        credit rating. The lower rated debt
                                        securities in which the Fund invests are
                                        considered speculative and are subject
                                        to greater volatility and risk of loss
                                        than investment grade securities,
                                        particularly in deteriorating economic
                                        conditions.

                                        The value of the Fund's investments in
                                        foreign securities also depends on
                                        changing currency values, different
                                        political and economic environments and
                                        other overall economic conditions in the
                                        countries where the Fund invests.
                                        Emerging market debt securities tend to
                                        be of lower credit quality and subject
                                        to greater risk of default than higher
                                        rated securities from more developed
                                        markets.

(1)       The management fee paid to the Adviser for providing services to the
          Fund consists of a basic annual fee of 0.35% of the Fund's average net
          assets and a performance adjustment. The actual fee paid to the
          Adviser may be higher or lower than the basic fee.

(2)       The Fund has adopted a Rule 12b-1 plan but has not yet charged any
          fees under the plan.

(3)       The Adviser has contractually agreed to reduce its fees and/or absorb
          expenses, and to pay for the Fund's distribution expenses and to limit
          the Fund's total annual operating expenses (excluding interest, taxes
          and extraordinary expenses) to 0.90% by limiting "other expenses" to
          0.20% and assuming the maximum management fee. This contract has a
          one-year term, renewable at the end of each fiscal year.

EXAMPLE

         Use this table to compare fees and expenses of the Fund with those of
other funds. It illustrates the amount of fees and expenses you would pay
assuming the following:

         -        $10,000 initial investment in the Fund
         -        5% annual return
         -        redemption at the end of each period
         -        no changes in the Fund's operating expenses

         Although your actual costs may be higher or lower, based on these
assumptions your costs would be:

                            FURTHER INFORMATION ABOUT
                    INVESTMENT OBJECTIVES, POLICIES AND RISKS
- -------------------------------------------------------------------------------



GENERAL

The Fund descriptions set forth in the Risk/Return Summary section of this
Prospectus are designed to help you choose the Fund that best fits your
investment objective. You may want to pursue more than one objective by
investing in more than one Fund. Each Fund's investment objective is a
fundamental policy, which cannot be changed without the approval of a majority
of the Fund's outstanding voting securities. There can be no assurance that any
objective will be met. In addition, each Fund may use certain types of
investments and investing techniques that are described in more detail in the
Statement of Additional Information.

DURATION

The Funds each invest in a diversified portfolio of fixed-income securities of
varying maturities with a different portfolio "duration." Duration is a measure
of the expected life of a fixed-income security that was developed as a more
precise alternative to the concept of "term to maturity." Duration incorporates
a bond's yield, coupon interest payments, final maturity, call and put features
and prepayment exposure into one measure. Traditionally, a fixed-income
security's "term to maturity" has been used to determine the sensitivity of the
security's price to changes in interest rates (which is the "interest rate risk"
or "volatility" of the security). However, "term to maturity" measures only the
time until a fixed-income security provides its final payment, taking no account
of the pattern of the security's payments prior to maturity. Duration is used in
the management of the Funds as a tool to measure interest rate risk. For
example, a Fund with a portfolio duration of 2 would be expected to change in
value 2% for every 1% move in interest rates. For a more detailed discussion of
duration, see "Investment Objectives and Policies--Duration" in the Statement of
Additional Information.

PORTFOLIO TURNOVER

Portfolio securities are sold whenever the Adviser believes it appropriate,
regardless of how long the securities have been held. Each Fund's investment
program emphasizes active portfolio management with a sensitivity to short-term
market trends and price changes in individual securities. Accordingly, the Funds
expect to take frequent trading positions, resulting in portfolio turnover that
may exceed those of most investment companies of comparable size. Portfolio
turnover generally involves some expense to the Funds, including brokerage
commissions, dealer markups and other transaction costs, and may result in the
recognition of capital gains that may be distributed to shareholders. Generally,
portfolio turnover over 100% is considered high and increases these costs. The
Adviser does not view turnover as an important consideration in managing the
Funds and does not strive to limit portfolio turnover. See "Financial
Highlights" for past turnover rates.

RISKS OF INVESTING IN EMERGING MARKET AND OTHER FOREIGN SECURITIES

Investments in emerging market and other foreign securities involve certain risk
considerations not typically associated with investing in securities of U.S.
issuers, including: (a) currency devaluations and other currency exchange rate
fluctuations; (b) political uncertainty and instability; (c) more substantial
government involvement in the economy; (d) higher rates of inflation; (e) less
government supervision and regulation of the securities markets and participants
in those markets; (f) controls on foreign investment and limitations on
repatriation of invested capital and on a Fund's ability to exchange local
currencies for U.S. dollars; (g) greater price volatility, substantially less
liquidity and significantly smaller capitalization of securities markets; (h)
absence of uniform accounting and auditing standards; (i) generally higher
commission expenses; (j) delay in settlement of securities transactions; and (k)
greater difficulty in enforcing shareholder rights and remedies.

RISKS OF INVESTING IN FIXED-INCOME SECURITIES

Other than the risks presented for the ALPHA TRAK 500 FUND from its use of
futures, the Funds are subject primarily to interest rate and credit risk.
Interest rate risk is the potential for a decline in bond prices due to rising
interest rates. In general, bond prices vary inversely with interest rates. The
change in bond price depends on several factors, including the bond's maturity
date. In general, bonds with longer maturities are more sensitive to changes in
interest rates than bonds with shorter maturities. Credit risk is the
possibility that a bond issuer will fail to make timely payments of interest or
principal to a Fund.

The Funds may invest a portion of their assets in non-investment grade debt
securities, commonly referred to as "junk bonds." Low-rated and comparable
unrated securities, while generally offering higher yields than investment grade
securities with similar maturities, involve greater risks, including the
possibility of default or bankruptcy. They are regarded as speculative with
respect to the issuer's capacity to pay interest and to repay principal. The
market values of certain of these securities tend to be more sensitive to
individual corporate development and changes in economic conditions than higher
quality bonds. In addition, low-rated and comparable unrated securities tend to
be less marketable than higher-quality debt securities because the market for
them is not as broad or active. The lack of a liquid secondary market may have
an adverse effect on market price and a Fund's ability to sell particular
securities.

RISKS OF USING CERTAIN DERIVATIVES

Participation in the options or futures markets involves investment risks and
transaction costs to which a Fund would not be subject absent the use of these
strategies. If the Adviser's predictions of movements in the direction of the
securities and interest rate markets are inaccurate, the adverse consequences to
a Fund may leave the Fund in a worse position than if such strategies were not
used. Risks inherent in the use of options, futures contracts and options on
futures contracts include: (i) dependence on the Adviser's ability to predict
correctly movements in the direction of interest rates and securities prices;
(ii) imperfect correlation between the price of options and futures contracts
and options thereon and movements in the prices of the securities being hedged;
(iii) the fact that skills needed to use these strategies are different from
those needed to select portfolio securities; (iv) the absence of a liquid
secondary market for any particular instrument at any time; (v) the possible
need to defer closing out certain hedged positions to avoid adverse tax
consequences; and (vi) the possible inability of a Fund to purchase or sell a
portfolio security at a time that otherwise would be favorable for it to do so,
or the possible need for the Fund to sell the security at a disadvantageous
time, due to the requirement that the Fund maintain "cover" or collateral
securities in connection with options and futures transactions. The Fund could
lose the entire amount it invests in futures. The loss from investing in other
derivatives is potentially unlimited. There also is no assurance that a liquid
secondary market will exist for futures contracts and options in which a Fund
may invest.

YEAR 2000

The Funds could be adversely affected if the computer systems used by the
Adviser and the Funds' other service providers do not properly process and
calculate date-related information from and after January 1, 2000. While year
2000-related computer problems could have a negative effect on the Funds, the
Adviser is working to avoid such problems and to obtain assurances from service
providers that they are taking similar steps.

ADVISER PERFORMANCE -- PREDECESSOR ACCOUNTS

LOW DURATION ASSETS

Set forth in the table below is certain performance data provided by the Adviser
relating to a performance record of the Adviser for at least six investment
advisory accounts (the "Low Duration Accounts"), during the period August 1,
1996 through December 31, 1996, utilizing the specific investment approach
specified for the Low Duration Bond Fund under "Investment Objectives and
Policies." The Low Duration Accounts constitute all of the accounts managed by
the Adviser that have an identical or substantially similar investment objective
or investment approach as the Low Duration Bond Fund. The Low Duration Accounts
were not subject to the same types of expenses to which the Low Duration Bond
Fund is subject, nor to the diversification requirements, specific tax
restrictions and investment limitations imposed on the Low Duration Bond Fund by
the Investment Company Act of 1940, as amended. From May 18, 1993 through July
31, 1996 performance data is for the Hotchkis and Wiley Low Duration Bond Fund
that Tad Rivelle and Laird Landmann, now Managing Director-Chief Investment
Officer and Managing Director of the Adviser, respectively, personally managed
in their capacities as principals and Co-Directors of Fixed Income for Hotchkis
and Wiley. The Low Duration Accounts and the Hotchkis and Wiley Low Duration
Bond Fund are collectively called the "Low Duration Assets." The Low Duration
Assets have been managed with investment objectives and investment policies and
strategies substantially similar to those to be employed by Mr. Rivelle and Mr.
Landmann in managing the Low Duration Bond Fund. The results presented are not
intended to predict or suggest the return to be experienced by the Low Duration
Bond Fund or the return an investor might achieve by investing in the Low
Duration Bond Fund. Investors should not rely on the following performance data
as an indication of future performance of the Adviser or of the Low Duration
Bond Fund.

** From May 18, 1993

Please read the following important notes concerning the Low Duration Assets.

1. Performance before August 1, 1996 was calculated using the standard total
return formula required by the Securities and Exchange Commission ("SEC") for
all mutual funds.

2. The results for the Low Duration Accounts reflect both income and capital
appreciation or depreciation (total return). Returns are time-weighted and net
of all applicable fees and expenses.

3. Annual rate of return for the Low Duration Accounts is calculated using the
modified Dietz method, which is defined as the portfolio gain (including all
realized and unrealized gains and losses as well as all income) over the average
capital for the period. Average capital is the beginning market value plus/minus
weighted subscriptions/redemptions. Calculation is done monthly, but is subject
to revaluation during the month when there is a cash flow that exceeds 10% of
the beginning market value of the Low Duration Accounts.

4. The Merrill Lynch 1 - 3 year U.S. Treasury Index is an unmanaged index of
U.S. Treasury securities with maturities of 1 to 3 years. The U.S. Treasury
securities included in this Index will differ substantially from the securities
in the Low Duration Fund.

ENHANCED EQUITY INDEX ASSETS

Set forth in the table below is certain performance data provided by the Adviser
relating to a performance record of the Adviser for one investment advisory
account (the "Enhanced Equity Index Account") during the period September 30,
1997 through May 31, 1998, utilizing the specific investment approach specified
for the AlphaTrak 500 Fund under "Investment Objectives and Policies." The
Enhanced Equity Index Account constitutes the only account managed by the
Adviser that has an identical or substantially similar investment objective or
investment approach as the AlphaTrak 500 Fund. The Enhanced Equity Index Account
was not subject to the same types of expenses to which the AlphaTrak 500 Fund is
subject, nor to the diversification requirements, specific tax restrictions and
investment limitations imposed on the AlphaTrak 500 Fund by the Investment
Company Act of 1940, as amended. The performance of the Enhanced Equity Index
Account may have been adversely affected had it been subject to the same
expenses, restrictions and limitations. The Adviser believes that any adverse
effect would not have been significant. The results presented are not intended
to predict or suggest the return to be experienced by the AlphaTrak 500 Fund or
the return an investor might achieve by investing in the AlphaTrak 500 Fund.
Investors should not rely on the following performance data as an indication of
future performance of the Adviser or of the AlphaTrak 500 Fund.

SPECIAL NOTE CONCERNING ADVISER INVESTMENT RETURNS: Investors should note that
the Funds will compute and disclose their average annual compounded rate of
return using the standard formula set forth in SEC rules, which differs in
certain respects from returns for the Accounts noted above. The SEC total return
calculation method calls for computation and disclosure of an average annual
compounded rate of return for one, five and ten year periods or shorter periods
from inception. The SEC formula provides a rate of return that equates a
hypothetical initial investment of $1,000 to an ending redeemable value. The
returns shown for the Accounts are net of advisory fees in accordance with the
SEC calculation formula, which requires that returns shown for the Funds be net
of advisory fees as well as all other applicable Fund operating expenses.
Performance was calculated on a trade date basis.

Adviser's affiliate, MWS, has managed fixed-income investments since 1992. MWS
managed approximately $20 billion for its clients as of March 31, 1999.

PORTFOLIO MANAGERS

The portfolio managers who have day-to-day responsibility for the management of
the Funds' portfolios are listed below, together with their biographical
information for the past five years.

SCOTT B. DUBCHANSKY has been the Chief Executive Officer of the Adviser since
August 1996. From August 1992 through August 1996, Mr. Dubchansky was a Senior
Vice President of Donaldson Lufkin & Jenrette in the Fixed Income Division.

INVESTMENT FUND.

STEPHEN KANE, CFA has been a portfolio manager with the Adviser since August
1996. From November 1995 until July 1996, Mr. Kane was a portfolio manager with
Hotchkis and Wiley in Los Angeles. From July 1992 until October 1995 he was an
account manager with PIMCO in Newport Beach, California. Before then, Mr. Kane
was a Merchant Banking Associate with Union Bank in Los Angeles, California. Mr.
Kane, together with Messrs. Landmann and Rivelle, manages the TOTAL RETURN BOND
FUND and the ALPHATRAK 500 FUND.

LAIRD R. LANDMANN has been a Managing Director and portfolio manager with the

was a principal and Co-Director of Fixed Income with Hotchkis and Wiley in Los
Angeles. Before then, he was a portfolio manager with PIMCO in Newport Beach,
California. Mr. Rivelle, together with Messrs. Kane and Landmann, manages the
TOTAL RETURN BOND FUND, the LOW DURATION BOND FUND and the ALPHATRAK 500 FUND.
Mr. Rivelle, together with Mr. Dubchansky, also manages the SHORT-TERM
INVESTMENT FUND.

MANAGEMENT FEES AND OTHER EXPENSES

Advisory Fees. Under the Investment Advisory Agreement relating to the TOTAL
RETURN BOND FUND, the Trust pays the Adviser a fee, computed daily and payable
monthly, at an annual rate of .55% of the Fund's average daily net assets.

Under the Investment Advisory Agreement relating to the LOW DURATION BOND FUND,
the Trust pays the Adviser a fee, computed daily and payable monthly, at an
annual rate of .48% of the Fund's average daily net assets.

Under the Investment Advisory Agreement relating to the SHORT-TERM INVESTMENT
FUND, the Trust pays the Adviser a fee, computed daily and payable monthly, at
an annual rate of .40% of the Fund's average daily net assets.

Under the Investment Advisory Agreement relating to the ALPHATRAK 500 FUND, the
Trust pays the Adviser a basic fee of .35% of the Fund's average daily net
assets. The basic fee may be adjusted upward or downward (by up to .35% of the
Fund's average daily net assets), depending on whether, and to what extent, the
investment performance of the AlphaTrak 500 Fund, for the relevant performance
period, exceeds or is exceeded by, the performance of the S&P 500 Index over the
same period.

                                       26
<PAGE>   32

The performance period consists of the prior three calendar months. Each .10% of
difference of the Fund's performance compared to the performance of the S&P 500
Index plus 1.00% is multiplied by a performance adjustment of .035%, up to a
maximum adjustment of .35% (as an annual rate). Thus, an annual excess
performance difference of 2.00% or more between the Fund and the S&P 500 Index
would result in an annual maximum performance adjustment of .35%. This formula
requires that the Fund's performance exceed the performance of the S&P 500 Index
by at least 1.00% before any upward adjustment is made to the basic fee. The
Fund's performance may still exceed the S&P 500 Index's performance (but by less
than 1.00%) and a reduction in the basic fee would occur.

Here are examples of how the adjustment would work (using annual rates):

   -8.00%       -10.00%       .35%        .35%        .70%
</TABLE>

The Fund's performance is calculated based on its net asset value per share
after expenses but before the advisory fee. For purposes of calculating the
performance adjustment, any dividends or capital gains distributions paid by the
Fund are treated as if those distributions were reinvested in Fund shares at the
net asset value per share as of the record date for payment. The performance
record for the S&P 500 Index is based on the change in value of that index, and
is adjusted for any cash distributions from the companies whose securities
comprise the S&P 500 Index.

Because the adjustment to the basic fee is based on the comparative performance
of the Fund and the record of the S&P 500 Index, the controlling factor
(regarding the adjustment to the basic fee) is not whether the Fund's
performance is up or down, but whether it is up or down more or less than the
performance record of the S&P 500 Index. Moreover, the comparative investment
record of the Fund is based solely on the relevant performance period without
regard to the cumulative performance over a longer or shorter period.

The advisory fee and any adjustment are calculated once per month (but accrued
daily based on the prior adjustment) and the entire advisory fee normally is
paid monthly. Shareholders should note that it is possible for high past
performance to result in a daily advisory fee accrual or monthly advisory fee
payment by the Fund that is higher than lower current performance would
otherwise produce.

Rule 12b-1 Fee. The Funds have a Share Marketing Plan or "12b-1 Plan" under
which they may finance activities primarily intended to sell shares, provided
the categories of expenses are approved in advance by the Board and the expenses
paid under the plan were incurred within the last 12 months and accrued while
the plan is in effect. Expenditures by a fund under the plan may not exceed .25%
of its average net assets annually (all of which may be for service fees).
Currently, the Board of Directors of the Funds have waived these fees for the
Funds, and the Adviser has contractually agreed, through March 31, 2000, to pay
the Funds' distribution expenses out of its own resources.

Compensation of Other Parties. The Adviser may in its discretion and out of its
own funds compensate third parties for the sale and marketing of the Funds and
for providing services to shareholders. The Adviser also may use its own funds
to sponsor seminars and educational programs on the Funds for financial
intermediaries and shareholders.

The Adviser also manages individual investment advisory accounts. The Adviser
reduces the fees charged to individual advisory accounts by the amount of the
investment advisory fee charged to that portion of the client's assets invested
in any Fund.

The Investment Advisory Agreement permits the Adviser to allocate brokerage
based on sales of shares of Funds managed by the Adviser. No such allocation has
been made to date.

THE ADMINISTRATOR

First Data Investor Services Group, Inc. ("Investor Services Group"), a wholly
owned subsidiary of First Data Corporation, serves as Administrator to the Trust
pursuant to an Administration Agreement. The principal business address of
Investor Services Group is 3200 Horizon Drive, P.O. Box 61767, King of Prussia,
Pennsylvania 19406.

THE DISTRIBUTOR

First Data Distributors, Inc., 4400 Computer Drive, Westboro, Massachusetts
01581, serves as principal underwriter to the Trust pursuant to an Underwriting
Agreement.

HOW TO PURCHASE SHARES

The minimum initial investment in each Fund is $5,000. For retirement plan
investments the initial minimum is $1,000. The Trust and the Transfer Agent
reserve the right to reject any order and to waive its minimum investment
requirements for shareholders investing through certain fund networks or other
financial intermediaries. In such cases, the minimums associated with the
policies and programs of the fund network or financial intermediary will apply.
Investors may invest in any Fund by wiring the amount to be invested to
Metropolitan West Funds.

         Wire to: Boston Safe Deposit & Trust
         ABA No. 01-10-01234 for First Data Investor
         Services Group, Inc.
         Account No. ___________
         Credit:  (Name of Fund)
         FBO:  (Shareholder name and account number)

The shareholder's bank may impose a fee for investments by wire. The Fund or the
Transfer Agent will not be responsible for the consequences of delays, including
delays in the banking or Federal Reserve wire systems. Wires received after the
close of the New York Stock Exchange will be considered received by the next
business day.

To ensure proper credit, before wiring any funds the shareholder must call (800)
241-4671 to notify us of the wire and to get an account number assigned if the
wire is an initial investment. Also, if the wire represents an initial
investment, the investor must mail an application form, by regular mail, to the
Transfer Agent at the following address:

Metropolitan West Funds
c/o First Data Investor Services Group, Inc.
3200 Horizon Drive
P.O. Box 61767
King of Prussia, Pennsylvania 19406

Investors may also purchase shares by sending a check payable to Metropolitan
West Funds, together with the application form to the address above.

Checks should be drawn on a U.S. bank and must be payable in U.S. dollars.
Shares of a Fund will be purchased for the account of the investor at the net
asset value next determined after receipt by the Transfer Agent, or an
authorized sub-agent, of the investor's wire or check. If a check is not honored
by the investor's bank, the investor will be liable for any loss sustained by
the Fund, as well as a $20 service charge imposed by the Transfer Agent. Forms
for additional contributions by check or change of address are provided on
account statements.

The Trust will only accept a check when the Trust is the primary payee. The
Trust may also accept orders from selected brokers, dealers and other qualified
institutions, with payment made to the Fund at a later time. The Adviser is
responsible for insuring that such payment is made on a timely basis. Investors
may be charged a fee if they buy or sell Fund shares through a broker or agent.

Shareholder inquiries should be directed to the Trust, c/o First Data Investor
Services Group, Inc., P.O. Box 61767, King of Prussia, PA 19406.

The Trust does not consider the U.S. Postal Service or other independent
delivery service to be its agent. Therefore, deposit in the mail or other
service does not constitute receipt by the Transfer Agent.

BY PAYMENT IN KIND

In certain situations, Fund shares may be purchased by tendering payment in kind
in the form of securities. Any securities used to buy Fund shares must be
readily marketable, their acquisition consistent with the Fund's objective and
otherwise acceptable to the Adviser. Prior to making such a purchase, you should
call the Adviser to determine if the securities you wish to use to make a
purchase are appropriate.

PURCHASES THROUGH AN INVESTMENT BROKER OR DEALER

You may buy and sell shares of the Funds through certain brokers (and their
agents) that have made arrangements with the Funds to sell their shares. When
you place your order with such a broker or its authorized agent, your order is
treated as if you had placed it directly with the Funds' Transfer Agent, and you
will pay or receive the next price calculated by the Funds. The broker (or
agent) holds your shares in an omnibus account in the broker' (or agent') name,
and the broker (or agent) maintains your individual ownership records. The Funds
may pay the broker or its agent for maintaining these records as well as
providing other shareholder services. The broker

                                       28
<PAGE>   34

(or its agent) may charge you a fee for handling your order. The broker (or
agent) is responsible for processing your order correctly and promptly, keeping
you advised regarding the status of your individual account, confirming your
transactions and ensuring that you receive copies of the Funds' prospectus.

NET ASSET VALUE

The net asset value per share of each Fund is determined on each day that banks
are open for business and the New York Stock Exchange is open for trading, as of
the close of regular trading on the New York Stock Exchange (usually 4:00 p.m.,
Eastern time). The net asset value per share is the value of the Fund's assets,
less its liabilities, divided by the number of shares of the Fund outstanding.
The value of a Fund's portfolio securities is determined on the basis of the
market value of such securities or, if market quotations are not readily
available, at fair value under guidelines established by the Trustees.
Short-term investments maturing in less than 60 days are valued at amortized
cost which the Board has determined to equal fair value. The daily net asset
value may not reflect the closing market price for all futures contracts held by
the Funds because the markets for certain futures will close shortly after the
time net asset value is calculated. See "Net Asset Value" in the Statement of
Additional Information for further information.

HOW TO REDEEM SHARES

REGULAR REDEMPTION

A shareholder may redeem shares at any time by delivering instructions by
regular mail to the Transfer Agent or selected brokers, dealers and other
qualified institutions. If you would like to send a package via overnight mail
to the Trust, c/o the Transfer Agent, the address is: 3200 Horizon Drive, P.O.
Box 61767, King of Prussia, Pennsylvania 19406.

The redemption request should identify the Fund and the account number, specify
the number of shares or dollar amount to be redeemed and be signed by all
registered owners exactly as the account is registered, and it will not be
accepted unless it contains all required documents. The shares will be redeemed
at the net asset value next determined after receipt of the request by the
Transfer Agent or other agent of the Funds. A redemption of shares is a sale of
shares and a shareholder may realize a taxable gain or loss.

If the proceeds of any redemption (a) exceed $50,000, (b) are paid to a person
other than the owner of record, or (c) are sent to an address or bank account
other than shown on the Transfer Agent' records, the signature(s) on the
redemption request must be guaranteed by a commercial bank or trust company in
the United States, a member firm of the National Association of Securities
Dealers, Inc., or other eligible guarantor institution. A notary public is not
an acceptable guarantor.

Additional documentation may be required for the redemption of shares held in
corporate, partnership or fiduciary accounts. In case of any questions, please
contact the Funds in advance by calling (800) 241-4671.

Redemptions will be processed only on a day during which the New York Stock
Exchange and banks are open for business. Investors who purchase shares by check
or money order will not have redemption requests processed until there is
reasonable belief that the check or money order has cleared, which may take up
to 15 calendar days after the purchase order.

EXCHANGES OF SHARES

Shareholders are permitted to exchange their shares in a Fund for shares of
other Funds in the Trust, provided that those shares may legally be sold in the
state of the investor's residence and the shareholder has selected the
appropriate box on the Account Application. Shares subject to an exchange must
have a current value of at least $1,000. An exchange of shares is treated for
federal income tax purposes as a redemption (sale) of shares given in exchange
by the shareholder and an exchanging shareholder may, therefore, realize a
taxable gain or loss in connection with the exchange. Shares exchanged for
shares of another Fund will be priced at their respective net asset values.

TELEPHONE TRANSACTIONS

You may redeem shares by telephone and have the proceeds wired to the bank
account as stated on the Transfer Agent's records. You may also exchange shares
by telephone. In order to redeem or exchange shares by telephone, you must
select the appropriate box on the Account Application. In order to arrange for
telephone redemptions or exchanges or change payment instructions after an
account has been opened or to change the bank account or address designated to
receive redemption proceeds, a written request must be sent to the Trust. The
request must be signed by each shareholder of the account with the signature
guarantees as described above. Once this feature has been requested, shares may
be redeemed or exchanged by calling Investor Services at (800) 241-4671 and
giving the account name, account number, and amount of the redemption or
exchange. Joint

                                       29
<PAGE>   35

accounts require only one shareholder to call. If redemption proceeds are to be
mailed or wired to the shareholder's bank account, the bank involved must be a
commercial bank located within the United States.

If an investor redeems shares by telephone and requests wire payment, payment of
the redemption proceeds will normally be made in federal funds on the next
business day provided that the redemption order is received by the Transfer
Agent before the relevant Fund's net asset value is calculated for the day.
There may be a charge of up to $10 for all wire redemptions. SHAREHOLDERS
EFFECTING TRANSACTIONS VIA WIRE TRANSFER MAY BE REQUIRED TO PAY FEES, INCLUDING
THE WIRE FEE AND OTHER FEES, THAT WILL BE DEDUCTED DIRECTLY FROM REDEMPTION
PROCEEDS.

The Funds reserve the right to reject any telephone redemption or exchange
request and the redemption or exchange privilege may be modified or terminated
at any time on 30-days' notice to shareholders. In an effort to prevent
unauthorized or fraudulent redemption or exchange requests by telephone, the
Trust and the Transfer Agent employ reasonable procedures specified by the Funds
to confirm that such instructions are genuine. Among the procedures used to
determine authenticity, investors electing to redeem or exchange by telephone
will be required to provide their account number or other identifying
information. All such telephone transactions will be tape recorded and confirmed
in writing to the shareholder. The Trust may implement other procedures from
time to time. If reasonable procedures are not implemented, the Trust and/or the
Transfer Agent may be liable for any loss due to unauthorized or fraudulent
transactions. In all other cases, the shareholder is liable for any loss for
unauthorized transactions. In periods of severe market or economic conditions,
the telephone redemption or exchange of shares may be difficult to implement and
shareholders should redeem shares by writing to the Transfer Agent at the
address listed above. If for any other reason a shareholder is unable to redeem
or exchange by telephone, shareholders should redeem or exchange shares by
writing to the Transfer Agent at the address listed above.

PAYMENTS

After the Transfer Agent has received the redemption request and all proper
documents, payment for shares tendered will generally be made within three
business days. Payment may be delayed or made partly in-kind with marketable
securities under unusual circumstances, as specified in the 1940 Act.

REDEMPTIONS OF SMALL ACCOUNTS

A Fund may redeem all of the shares of any shareholder whose account has
declined to a net asset value of less than $500, as a result of a transfer or
redemption, at the net asset value determined as of the close of business on the
business day preceding the sending of the proceeds of such redemption. The Trust
would give shareholders whose shares were being redeemed 60-days' prior written
warning in which to purchase sufficient shares to avoid such redemption.

WITHHOLDINGS; REPORTING

The Fund may be required to withhold federal income tax, at a rate of 31%, from
proceeds of redemptions, if the shareholder is subject to backup withholding.
Failure to provide a certified tax identification number at the time an account
is opened will cause tax to be withheld. A Fund also may be required to report
redemptions to the Internal Revenue Service.

REPORTS TO SHAREHOLDERS

Each Fund's fiscal year ends on March 31. Each Fund will issue to its
shareholders semi-annual and annual reports. In addition, shareholders will
receive quarterly statements of the status of their accounts reflecting all
transactions having taken place within that quarter. In order to reduce
duplicate mailings and printing costs, the Trust will provide one annual or
semi-annual report and annual prospectus per household. Information regarding
the tax status of income dividends and capital gains distributions will be
mailed to shareholders on or before January 31st of each year. Account tax
information will also be sent to the IRS.

DIVIDENDS AND TAX STATUS

The Funds (except the AlphaTrak 500 Fund) expect to declare dividends daily and
pay them monthly to shareholders. The AlphaTrak 500 Fund expects to declare and
pay dividends to shareholders quarterly.

Distributions from net realized short-term gains, if any, and distributions from
any net capital gains realized through October 31st of each year and not
previously paid out will be paid out after that date; each Fund may also pay
supplemental distributions after the end of the Fund's fiscal year. Dividends
and distributions are paid in full and fractional shares of each Fund based on
the net asset value per share at the close of business on the ex-dividend date,
unless the shareholder requests, in writing to the Trust, payment in cash. The
Trust will notify each

                                       30
<PAGE>   36

shareholder after the close of its fiscal year of both the dollar amount and the
tax status of that year's distributions.

All dividends from net investment income together with distributions of
short-term capital gains will be taxable as ordinary income to the shareholders
even though paid in additional shares. Any net capital gains ("capital gains
distributions") distributed to shareholders are taxable as the relevant type of
capital gains to the shareholders regardless of the length of time a shareholder
has owned his shares. Dividends, interest and gains received by a Fund may be
subject to withholding and other taxes imposed by foreign countries. Tax
conventions between certain countries and the U.S. may reduce or eliminate these
foreign taxes.

Distributions will be taxable in the year in which they are received, except for
certain distributions received in January, which will be taxable as if received
the prior December. Shareholders of a Fund will be informed annually of the
amount and nature of the Fund's distributions, including the portions, if any,
that qualify for the dividends-received deduction, that are capital gain
distributions, and that are a return of capital.

Additional information about taxes is set forth in the Statement of Additional
Information. The foregoing discussion has been prepared by the management of the
Funds, and does not purport to be a complete description of all tax implications
of an investment in a Fund. Shareholders should consult their own advisors
concerning the application of federal, state and local tax laws to their
particular situations.

                                    THE TRUST



     The Trust was organized on December 9, 1996 as a Delaware business trust.
The Trust is a diversified open-end, management investment company currently
consisting of four separate series. Each series has only one class of shares of
beneficial interest, with a par value of $0.01 per share. The Trust's Board of
Trustees decides matters of general policy and reviews the activities of the
Adviser. The Trust's officers conduct and supervise the daily business
operations of the Trust. Each Fund is a series of shares of the Trust, having
separate assets and liabilities. The Board of Trustees may, at its own
discretion, create additional series of shares and classes within series.


                       INVESTMENT OBJECTIVES AND POLICIES


     The investment objective of each Fund is described in the Prospectus.

     The portfolio, and strategies with respect to the composition of each Fund,
are described in the Prospectus.



INVESTMENT RESTRICTIONS


     Each Fund has adopted the following restrictions (in addition to those
indicated in the Prospectus) as fundamental policies, which may not be changed
without the favorable vote of the holders of a "majority" of that Fund's
outstanding voting securities, as defined in the Investment Company Act of 1940,
as amended (the "1940 Act"). Under the 1940 Act, the vote of the holders of a
"majority" of a Fund's outstanding voting securities means the vote of the
holders of the lesser of (i) 67% of the shares of the Fund represented at a
meeting at which the holders of more than 50% of its outstanding shares are
represented or (ii) more than 50% of the outstanding shares.


     Except as noted, no Fund may:


     1.   Purchase any security, other than obligations of the U.S. Government,
          its agencies, or instrumentalities ("U.S. Government securities") or
          mutual funds, if as a result of that purchase: (i) with respect to 75%
          of its total assets, more than 5% of the Fund's total assets
          (determined at the time of investment) would then be invested in
          securities of a single issuer, or (ii) more than 25% of the Fund's
          total assets (determined at the time of investment) would be invested
          in one or more issuers having their principal business activities in a
          single industry.


     2.   Purchase securities on margin (but any Fund may obtain such short-term
          credits as may be necessary for the clearance of transactions),
          provided that the deposit or payment by a Fund of initial or
          maintenance margin in connection with futures or options is not
          considered the purchase of a security on margin.

     3.   Make short sales of securities or maintain a short position, unless at
          all times when a short position is open it owns an equal amount of
          such securities or securities convertible into or exchangeable,
          without payment of any further consideration, for securities of the
          same issue as, and equal in amount to, the securities sold short
          (short sale against-the-box), and unless not more than 25% of the
          Fund's net assets (taken at current value) is held as collateral for
          such sales at any one time.

     4.   Issue senior securities, borrow money or pledge its assets, except
          that any Fund may borrow from a bank for temporary or emergency
          purposes in amounts not exceeding 10% (taken at the lower of cost or
          current value) of its total assets (not including the amount borrowed)
          and pledge its assets to secure such borrowings. The Funds may borrow
          from banks or enter into reverse repurchase agreements and pledge
          assets in connection therewith, but only if immediately after each
          borrowing there is asset coverage of at least 300%.


     5.   Purchase any security (other than U.S. Government securities) if as a
          result of that purchase, with respect to 75% of the Fund's total
          assets, the Fund would then hold more than 10% of the outstanding
          voting securities of an issuer.


     6.   Act as an underwriter except to the extent that, in connection with
          the disposition of portfolio securities, it may be deemed to be an
          underwriter under certain federal securities laws.

     7.   Make investments for the purpose of exercising control or management.





                                                                        Page B-3
<PAGE>   43



     8.   Participate on a joint or joint and several basis in any trading
          account in securities, except to the extent the Fund has received an
          exemptive order from the Securities and Exchange Commission permitting
          such account.


     9.   Invest in commodities, except that the Fund may invest in futures
          contracts or options on futures contracts (a) for bona fide hedging
          purposes within the meaning of regulations of the Commodity Futures
          Trading Commission "CFTC"), or (b) for other than bona fide hedging
          purposes if, as a result thereof, no more than 5% of that Fund's total
          assets (taken at market value at the time of entering into the
          contract) would be committed to initial deposits and premiums on open
          futures contracts and options on such contracts (excluding
          in-the-money amounts). (This exception is an operating policy that may
          be changed without shareholder approval, consistent with applicable
          regulations.)



     In addition, the Trust has adopted the following non-fundamental policies
so that no Fund will: (a) invest in interests in oil, gas, or other mineral
leases or exploration of development programs, although it may invest in the
common stocks of companies that invest in or sponsor such programs; (b) invest
more than 15% of its net assets in illiquid securities, excluding restricted
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933, as amended ("Securities Act"), that have been determined to be liquid
pursuant to procedures adopted by the Board of Trustees; and (c) purchase
securities of other investment companies, except in connection with a merger,
consolidation, reorganization or other acquisition of assets or except as
disclosed in the Prospectus or this Statement of Additional Information, but not
more than 3% of the total outstanding voting stock of such company would be
owned by the Fund.


                   SECURITIES AND TECHNIQUES USED BY THE FUNDS

     The following provides more detailed information about securities and
techniques used by the Funds and the risks associated with them.

GENERAL

     The Funds will attempt to achieve their objectives by investing in the
following types of securities that may be issued by domestic or foreign
entities: (i) U.S. Government securities; (ii) corporate debt securities,
including bonds, notes and debentures; (iii) corporate and asset-backed
commercial paper; (iv) mortgage- and other asset-backed securities, including
CMOs and REMICs (see "Mortgage Related Securities"); (v) variable and floating
rate debt securities (including inverse floaters); (vi) subordinated corporate,
mortgage, and asset-backed securities; (vii) structured debentures, bonds and
notes; (viii) bank certificates of deposit; (ix) fixed time deposits and
bankers' acceptances; (x) repurchase agreements and reverse repurchase
agreements; (xi) debt securities that are convertible into or exchangeable for
equity securities ("convertible securities"); (xii) preferred equity securities;
(xiii) obligations of foreign governments or their subdivisions, agencies and
instrumentalities; (xiv) obligations of international agencies (such as the
Agency for International Development) or supranational entities; and (xv)
privately placed and Rule 144A securities. There is no limitation on the
percentage of a Fund's assets that may be committed to any of these types of
securities, except to the extent that a security may be deemed to be illiquid.

     In addition to the securities above, the ALPHATRAK 500 FUND may invest all
of its assets in the following equity derivative instruments (and in liquid
assets backing its investments in these derivatives): (i) S&P 500 Index futures
contracts; (ii) Mini S&P 500 Index futures contracts ("E-Mini"); (iii) options
on the S&P 500 Index and S&P futures; (iv) swap agreements involving the S&P 500
Index. When the above-listed S&P 500 Index derivatives appear to be overvalued
relative to the S&P 500 Index, the Fund may invest up to 100% in the common
stocks that comprise the S&P 500 Index. The Fund would not purchase all 500
issues, but would purchase a basket of common stocks represented in the S&P 500
Index that, in the opinion of the Adviser, will substantially track the
movements in the S&P 500 Index. The Fund may also invest up to 25% of its total
assets in these stocks indirectly by purchasing interests in one or more mutual
funds, asset pools or trusts that invest in such stocks.

     Positions in S&P 500 Index futures and options will be entered into only to
the extent they constitute permissible positions for the Fund according to
applicable rules of the Commodity Futures Trading Commission ("CFTC"). At times,
the Adviser may be constrained in its ability to use S&P 500 Index derivatives
either by requirements of the Internal Revenue Code or by an unanticipated
inability to close positions when it would be most advantageous to do so.

     Because each Fund may invest up to 25% of its total assets in money market
mutual funds or mutual funds that invest in stocks, investors should know that a
Fund would pay the additional fees and expenses of a mutual fund investment.
This would result in an additional layer of management fees and expenses for
shareholders in a Fund.



                                                                        Page B-4
<PAGE>   44




CREDIT RATINGS

     The Prospectus describes the permissible range of credit ratings for the
securities in which each Fund is permitted to invest. Securities rated Baa are
considered by Moody's to have speculative characteristics. For Baa/BBB rated
securities, changes in economic conditions or other circumstances are more
likely to lead to a weakened capacity to make principal and interest payments
than is the case with higher grade securities. Securities rated below BBB or Baa
are judged to be predominantly speculative with respect to their capacity to pay
interest and repay principal in accordance with the terms of their obligations
and are commonly known as "junk bonds."

     After its purchase by one of the Funds, a security may be assigned a lower
rating or cease to be rated. This would not require the Fund to sell the
security, but the Adviser will consider such an event in determining whether the
Fund should continue to hold the security in the portfolio.

DURATION

     In selecting fixed-income securities for the Funds, the Adviser makes use
of the concept of duration. Duration is a measure of the expected life of a
fixed-income security on a present value basis. Most debt obligations provide
interest ("coupon") payments in addition to a final ("par") payment at maturity.
Some obligations also have call provisions. Depending on the relative magnitude
of these payments, the market values of debt obligations may respond differently
to changes in the level and structure of interest rates. Duration takes the
length of time intervals between the present time and the time that the interest
and principal payments are scheduled or, in the case of a mortgage-backed,
asset-backed, or callable bond, expected to be received, and weights them by the
present values of the cash to be received at each future point in time.

     For any fixed-income security with interest payments occurring before the
payment of principal, duration is ordinarily less than maturity. In general, all
other things being equal, the lower the stated or coupon rate of interest of a
fixed-income security, the longer the duration of the security; conversely, the
higher the stated or coupon rate of interest of a fixed-income security, the
shorter the duration of the security. There are some situations where even the
standard duration calculation does not properly reflect the interest rate
exposure of a security. In these and other similar situations, the Adviser will
use more sophisticated analytical techniques that incorporate the economic life
of a security into the determination of its interest rate exposure. A Fund's
computation of duration is based on estimated rather than known factors. Thus,
there can be no assurance that a particular portfolio duration will at all times
be achieved by a Fund.

     Futures, options and options on futures have durations, which, in general,
are closely related to the duration of the securities which underlie them.
Holding long futures or call option positions will lengthen a Fund's duration by
approximately the same amount that holding an equivalent amount of the
underlying securities would.

     Short futures or put option positions have durations roughly equal to the
negative of the duration of the securities that underlie those positions, and
have the effect of reducing portfolio duration by approximately the same amount
that selling an equivalent amount of the underlying securities would.

     There are some situations where even the standard duration calculation does
not properly reflect the interest rate exposure of a security. For example,
floating and variable rate securities often have final maturities of ten or more
years; however, their interest rate exposure corresponds to the frequency that
coupon is reset. Another example where the interest rate exposure is not
properly captured by duration is the case of mortgage pass-through securities.
The stated final maturity of such securities is generally 30 years, but current
prepayment rates are more critical in determining the securities' interest rate
exposure. In these and other similar situations, the Adviser will use more
sophisticated analytical techniques that incorporate the economic life of a
security into the determination of its interest rate exposure.

     Assuming an expected average duration of .75 for the SHORT-TERM INVESTMENT
FUND, a 1% decline in interest rates would cause the Fund to gain .75% in value;
likewise, a 1% rise in interest would produce a decline of .75% in the Fund's
value. Assuming an expected average duration of 2 for the LOW DURATION BOND
FUND, a 1% decline in interest rates would cause the Fund to gain 2% in value;
likewise, a 1% rise in interest rates would produce a decline of 2% in the
Fund's value. Assuming an expected average duration of 4.5 for the TOTAL RETURN
BOND FUND, a 1% decline in interest rates would cause the Fund to gain 4.5% in
value; likewise, a 1% rise in interest rates would produce a decline of 4.5% in
the Fund's value. Assuming an expected duration of .75 for the ALPHATRAK 500
FUND, a 1% decline in interest rates would cause the Fund to gain .75% in value;
likewise, a 1% rise in interest rates would produce a .75% decline in the value
of the Fund. It should be noted, however, that the above assumptions (regarding
the ALPHATRAK 500 FUND) do not reflect any changes in S&P 500 Index futures
contracts, other derivatives or S&P 500 Index stocks



                                                                        Page B-5

that may be held by the Fund. Other factors such as changes in credit quality,
prepayments, the shape of the yield curve and liquidity affect the net asset
value of the Funds and may be correlated with changes in interest rates. These
factors can increase swings in the Fund's share prices during periods of
volatile interest rate changes.


REPURCHASE AGREEMENTS


     Each Fund may enter into repurchase agreements involving U.S. Government
securities or other collateral including mortgage-related products or corporate
securities with commercial banks or broker-dealers, whereby the seller of a
security agrees to repurchase the security from the Fund on an agreed-upon date
in the future. While each Fund intends to be fully collateralized as to such
agreements, and the collateral will be marked to market daily, if the person
obligated to repurchase from the Fund defaults, there may be delays and expenses
in liquidating the securities subject to the repurchase agreement, a decline in
their value and a loss of interest income.


     A repurchase transaction occurs when, at the time a Fund purchases a
security, that Fund also resells it to a vendor (normally a commercial bank or
broker-dealer) and must deliver the security (and/or securities substituted for
them under the repurchase agreement) to the vendor on an agreed-upon date in the
future. Such securities, including any securities so substituted, are referred
to as the "Resold Securities." The resale price is in excess of the purchase
price in that it reflects an agreed-upon market interest rate effective for the
period of time during which the Fund's money is invested in the Resold
Securities. The majority of these transactions run from day to day, and the
delivery pursuant to the resale typically will occur within one to five days of
the purchase. The Fund's risk is limited to the ability of the vendor to pay the
agreed-upon sum at the delivery date; in the event of bankruptcy or other
default by the vendor, there may be possible delays and expenses in liquidating
the instrument purchased, decline in its value and loss of interest. The Adviser
will consider the creditworthiness of any vendor of repurchase agreements.
Repurchase agreements can be considered as loans "collateralized" by the Resold
Securities, and are defined as "loans" in the 1940 Act. The return on such
collateral may be more or less than that from the repurchase agreement. The
Resold Securities will be marked to market every business day so that the value
of the collateral is at least equal to the value of the loan, including the
accrued interest earned thereon. All Resold Securities will be held by the
Fund's custodian either directly or through a securities depository (tri-party
repurchase agreement) or the Federal Reserve book-entry system.


REVERSE REPURCHASE AGREEMENTS

     The Funds may enter into reverse repurchase agreements, whereby a Fund
sells securities concurrently with entering into an agreement to repurchase
those securities at a later date at a fixed price. During the reverse repurchase
agreement period, the Fund continues to receive principal and interest payments
on those securities. Reverse repurchase agreements are speculative techniques
involving leverage and are considered borrowings by the Fund for purposes of the
percentage limitations applicable to borrowings.


U.S. GOVERNMENT SECURITIES


     The Funds may invest in U.S. Government securities. U.S. Government
securities include direct obligations issued by the United States Treasury, such
as Treasury bills, certificates of indebtedness, notes, bonds and component
parts of notes or bonds (including the principal of such obligations or the
interest payments scheduled to be paid on such obligations). U.S. Government
securities also include securities issued or guaranteed by U.S. Government
agencies and instrumentalities that issue or guarantee securities, including,
but not limited to, the Federal National Mortgage Association ("FNMA"),
Government National Mortgage Association ("GNMA"), Federal Home Loan Banks,
Federal Financing Bank, Student Loan Marketing Association. Federal Home Loan
Mortgage Corporation, Federal Intermediate Credit Banks, Federal Land Banks,
Tennessee Valley Authority, Inter-American Development Bank, Asian Development
Bank and the International Bank for Reconstruction and Development.


     Except for U.S. Treasury securities, obligations of U.S. Government
agencies and instrumentalities may or may not be supported by the full faith and
credit of the United States. Some are backed by the right of the issuer to
borrow from the Treasury; others by discretionary authority of the U.S.
Government to purchase the agencies' obligations; while still others, such as
the Student Loan Marketing Association, are supported only by the credit of the
instrumentality. In the case of securities not backed by the full faith and
credit of the United States, the investor must look principally to the agency or
instrumentality issuing or guaranteeing the obligation for ultimate repayment,
and may not be able to assert a claim against the United States itself in the
event the agency or instrumentality does not meet its commitment. Each Fund will
invest in securities of such instrumentality only when the Adviser is satisfied
that the credit risk with respect to that instrumentality is acceptable.




                                                                        Page B-6
<PAGE>   46





     Among the U.S. Government securities that may be purchased by the Funds are
certain "mortgage-backed securities" of GNMA, the Federal Home Loan Mortgage
Corporation ("FHLMC") and FNMA. See the discussion under "Mortgage-Related
Securities."


     The Funds may invest in component parts of the U.S. Treasury notes or
bonds, namely, either the principal of such Treasury obligations or one of the
interest payments scheduled to be paid on such obligations. These obligations
may take the form of (i) Treasury obligations from which the interest coupons
have been stripped, (ii) the interest coupons that are stripped, (iii)
book-entries at a Federal Reserve member bank representing ownership of Treasury
obligation components, or (iv) receipts evidencing the component parts
(principal or interest) of Treasury obligations that have not actually been
stripped. Such receipts evidence ownership of component parts of Treasury
obligations (principal or interest) purchased by a third party (typically an
investment banking firm) and held on behalf of the third party in physical or
book-entry form by a major commercial bank or trust company pursuant to a
custody agreement with the third party. These custodial receipts are known by
various names, including "Treasury Receipts," "Treasury Investment Growth
Receipts" (TIGRs) and "Certificates of Accrual on Treasury Securities" (CATS),
and are not issued by the U.S. Treasury, therefore they are not U.S. Government
securities, although the underlying bonds represented by these receipts are debt
obligations of the U.S. Treasury.


CORPORATE DEBT AND OTHER OBLIGATIONS

     The Funds may invest in corporate debt securities, variable and floating
rate debt securities and corporate commercial paper in the rating categories
described above. Floating rate securities normally have a rate of interest which
is set as a specific percentage of a designated base rate, such as the rate on
Treasury bonds or bills or the prime rate at a major commercial bank. The
interest rate on floating rate securities changes periodically when there is a
change in the designated base rate. Variable rate securities provide for a
specified periodic adjustment in the interest rate based on prevailing market
rates.

     The Funds may invest in corporate debt securities with contractual call
provisions that permit the seller of the security to repurchase the security at
a pre-determined price. The market price typically reflects the presence of a
call provision.

     The Funds may invest in structured debentures and structured notes. These
are hybrid instruments with characteristics of both bonds and swap agreements.
Like a bond, these securities make regular coupon payments and generally have
fixed principal amounts. However, the coupon payments are typically tied to a
swap agreement which can be affected by changes in a variety of factors such as
exchange rates, the shape of the yield curve and foreign interest rates. Because
of these factors, structured debentures and structured notes can display price
behavior that is more volatile than and often not correlated to other
fixed-income securities.

     The Funds may also invest in inverse floaters and tiered index bonds. An
inverse floater is a type of derivative that bears a floating or variable
interest rate that moves in the opposite direction to the interest rate on
another security or index level. Changes in the interest rate of the other
security or index inversely affect the residual interest rate paid on the
inverse floater, with the result that the inverse floater's price will be
considerably more volatile than that of a fixed-rate bond. Tiered index bonds
are also a type of derivative instrument. The interest rate on a tiered index
bond is tied to a specified index or market rate. So long as this index or
market rate is below a predetermined "strike" rate, the interest rate on the
tiered index bond remains fixed. If, however, the specified index or market rate
rises above the "strike" rate, the interest rate on the tiered index bond will
decrease. In general, the interest rates on tiered index bonds and inverse
floaters move in the opposite direction of prevailing interest rates. The market
for inverse floaters and tiered index bonds is relatively new. These corporate
debt obligations may have characteristics similar to those of mortgage-related
securities, but corporate debt obligations, unlike mortgage-related securities,
are not subject to prepayment risk other than through contractual call
provisions which generally impose a penalty for prepayment.

     A Fund's investments in U.S. dollar or foreign currency-denominated
corporate debt securities of domestic or foreign issuers are limited to
corporate debt securities (corporate bonds, debentures, notes or other similar
corporate debt instruments) which meet the minimum ratings criteria set forth
for the Fund, or, if unrated, which are in the Adviser's opinion comparable in
quality to corporate debt securities in which the Fund may invest. These
criteria are described in the Prospectus. The rate of return or return of
principal on some debt obligations may be linked or indexed to the level of
exchange rates between the U.S. dollar and a foreign currency or currencies.


CONVERTIBLE SECURITIES

     The Funds may invest in convertible securities of domestic or foreign
issuers, that meet the ratings criteria set forth in the Prospectus. A
convertible security is a fixed-income security (a bond or preferred stock)
which may be converted at a stated price within a specific period of time into a
certain quantity of common stock or other equity securities of the same or a
different issuer.




                                                                        Page B-7
<PAGE>   47




Convertible securities rank senior to common stock in a corporation's capital
structure but are usually subordinated to similar non-convertible securities.
While providing a fixed-income stream (generally higher in yield than the income
derivable from common stock but lower than that afforded by a similar
non-convertible security), a convertible security also offers an investor the
opportunity, through its conversion feature, to participate in the capital
attendant upon a market price advance in the convertible security's underlying
common stock.

     In general, the market value of a convertible security is at least the
higher of its "investment value" (i.e., its value as a fixed-income security) or
its "conversion value" (i.e., its value upon conversion into its underlying
stock). As a fixed-income security, a convertible security tends to increase in
market value when interest rates decline and tends to decrease in value when
interest rates rise. However, the price of a convertible security is also
influenced by the market value of the security's underlying stock. The price of
a convertible security tends to increase as the market value of the underlying
stock rises, whereas it tends to decrease as the market value of the underlying
stock declines. While no securities investment is without some risk, investments
in convertible securities generally entail less risk than investments in the
stock of the same issuer.


LOANS OF PORTFOLIO SECURITIES

     For the purpose of achieving income, a Fund may lend its portfolio
securities, provided: (i) the loan is secured continuously by collateral
consisting of short-term, high quality debt securities, including U.S.
Government securities, negotiable certificates of deposit, bankers' acceptances
or letters of credit, maintained on a daily marked-to-market basis in an amount
at least equal to the current market value of the securities loaned; (ii) the
Fund may at any time call the loan and obtain the return of the securities
loaned; (iii) the Fund will receive any interest or dividends paid on the loaned
securities; and (iv) the aggregate market value of securities loaned will not at
any time exceed one-third of the total assets of the Fund.

WHEN-ISSUED SECURITIES

     The Funds may purchase securities on a when-issued or delayed-delivery
basis, generally in connection with an underwriting or other offering.
When-issued and delayed-delivery transactions occur when securities are bought
with payment for and delivery of the securities scheduled to take place at a
future time, beyond normal settlement dates, generally from 15 to 45 days after
the transaction. The price that the Fund is obligated to pay on the settlement
date may be different from the market value on that date. While securities may
be sold prior to the settlement date, the Funds intend to purchase such
securities with the purpose of actually acquiring them, unless a sale would be
desirable for investment reasons. At the time the Fund makes a commitment to
purchase a security on a when-issued basis, it will record the transaction and
reflect the value of the security each day in determining the Fund's net asset
value. The Fund will also designate liquid securities, marked-to-market daily,
equal in value to its obligations for when-issued securities.

SHORT SALES

     If a Fund anticipates that the price of a security will decline, it may
sell the security "short" and borrow the same security from a broker or other
institution to complete the sale. The Fund may make a profit or loss depending
upon whether the market price of the security decreases or increases between the
date of the short sale and the date on which the Fund must replace the borrowed
security. Until the security is replaced, the Fund generally is required to pay
to the lender amounts equal to any interest which accrues during the period of
the loan. To borrow the security, the Fund also may be required to pay a
premium, which would also increase the cost of the security sold. The proceeds
of the short sale will be retained by the broker (or by the Fund's custodian in
a special custody account), to the extent necessary to meet the margin
requirements, until the short position is closed out.

     Until the Fund closes its short position or replaces the borrowed security,
the Fund will designate liquid securities at such a level that (i) the amount
deposited in the account plus the amount deposited with the broker as collateral
will equal the current value of the security sold short and (ii) the amount
designated plus the amount deposited with the broker as collateral will not be
less than the market value of the security at the time it was sold short.

     A Fund may not make short sales of securities or maintain a short position
if more than 25% of the Fund's net assets (taken at current value) are held as
collateral for such sales at any one time.


MORTGAGE-RELATED SECURITIES

     The Funds may invest in residential or commercial mortgage-related
securities, including mortgage pass-through securities, collateralized mortgage
obligations ("CMOs"), adjustable rate mortgage securities, CMO residuals,
stripped mortgage-related




                                                                        Page B-8
<PAGE>   48





securities, floating and inverse floating rate securities and tiered index
bonds. CMOs and other mortgage-related securities that are issued or guaranteed
by the U.S. Government or by any of its agencies or instrumentalities will be
considered U.S. Government securities for purposes of applying a Fund's
diversification tests. Generally, the entity that has the ultimate
responsibility for the payment of interest and principal on a security is deemed
to be the issuer of an obligation.


     MORTGAGE PASS-THROUGH SECURITIES: Mortgage pass-through securities
represent interests in pools of mortgages in which payments of both principal
and interest on the securities are generally made monthly, in effect "passing
through" monthly payments made by borrowers on the residential or commercial
mortgage loans which underlie the securities (net of any fees paid to the issuer
or guarantor of the securities). Mortgage pass-through securities differ from
other forms of debt securities, which normally provide for periodic payment of
interest in fixed amounts with principal payments at maturity or specified call
dates. Early payment of principal on mortgage pass-through securities (arising
from prepayments of principal due to the sale of underlying property,
refinancing, or foreclosure, net of fees and costs which may be incurred) may
expose a Fund to a lower rate of return upon reinvestment of principal. Also, if
a security subject to repayment has been purchased at a premium, in the event of
prepayment, the value of the premium would be lost.

     There are currently three types of mortgage pass-through securities, (i)
those issued by the U.S. Government or one of its agencies or instrumentalities,
such as the Government National Mortgage Association ("GNMA"), the Federal
National Mortgage Association ("FNMA") and the Federal Home Loan Mortgage
Corporation ("FHLMC"); (ii) those issued by private issuers that represent an
interest in or are collateralized by pass-through securities issued or
guaranteed by the U.S. Government or one of its agencies or instrumentalities;
and (iii) those issued by private issuers that represent an interest in or are
collateralized by whole mortgage loans or pass-through securities without a
government guarantee but usually having some form of private credit enhancement.

     GNMA is a wholly-owned United States Government corporation within the
Department of Housing and Urban Development. GNMA is authorized to guarantee,
with the full faith and credit of the United States Government, the timely
payment of principal and interest on securities issued by the institutions
approved by GNMA (such as savings and loan institutions, commercial banks and
mortgage banks), and backed by pools of FHA-insured or VA-guaranteed mortgages.

     Obligations of FNMA and FHLMC are not backed by the full faith and credit
of the United States Government. In the case of obligations not backed by the
full faith and credit of the United States Government, a Fund must look
principally to the agency issuing or guaranteeing the obligation for ultimate
repayment. FNMA and FHLMC may borrow from the U.S. Treasury to meet their
obligations, but the U.S. Treasury is under no obligation to lend to FNMA or
FHLMC.

     Private mortgage pass-through securities are structured similarly to GNMA,
FNMA and FHLMC mortgage pass-through securities and are issued by originators of
and investors in mortgage loans, including depository institutions, mortgage
banks, investment banks and special purpose subsidiaries of the foregoing. Pools
created by private mortgage pass-through issuers generally offer a higher rate
of interest than government and government-related pools because there are no
direct or indirect government or agency guarantees of payments in the private
pools. However, timely payment of interest and principal of these pools may be
supported by various forms of insurance or guarantees, including individual
loan, title, pool and hazard insurance and letters of credit. The insurance and
guarantees are issued by governmental entities, private insurers and the
mortgage poolers. The insurance and guarantees and the credit worthiness of the
issuers thereof will be considered in determining whether a mortgage-related
security meets the Funds' investment quality standards. There can be no
assurance that the private insurers or guarantors can meet their obligations
under the insurance policies or guarantee arrangements. Private mortgage
pass-through securities may be bought without insurance or guarantees if,
through an examination of the loan experience and practices of the
originator/services and poolers, the Adviser determines that the securities meet
the Funds' quality standards.


     COLLATERALIZED MORTGAGE OBLIGATIONS: CMOs, including CMOs that have elected
to be treated for federal income tax purposes as Real Estate Mortgage Investment
Conduits ("REMICs"), are hybrid instruments with characteristics of both bonds
and mortgage pass-through securities. CMOs are debt obligations collateralized
by residential or commercial mortgage loans or residential or commercial
mortgage pass-through securities. Interest and prepaid principal are generally
paid monthly. CMOs may be collateralized by whole mortgage loans or private
mortgage pass-through securities but are more typically collateralized by
portfolios of mortgage pass-through securities guaranteed by GNMA, FHLMC or
FNMA. The issuer of a series of CMOs may elect to be treated for tax purposes as
a REMIC. All future references to CMOs shall also be deemed to include REMICs.


     CMOs are structured into multiple classes, each bearing a different stated
maturity. Monthly payment of principal received from the pool of underlying
mortgages, including prepayments, is first returned to investors holding the
shortest maturity class.




                                                                        Page B-9
<PAGE>   49




Investors holding the longer maturity classes usually receive principal only
after shorter classes have been retired. An investor may be partially protected
against a sooner than desired return of principal because of the sequential
payments.

     Certain issuers of CMOs are not considered investment companies pursuant to
a rule recently adopted by the Securities and Exchange Commission ("SEC"), and
the Funds may invest in the securities of such issuers without the limitations
imposed by the 1940 Act on investments by the Fund in other investment
companies. In addition, in reliance on an earlier SEC interpretation, the Fund's
investments in certain other qualifying CMOs, which cannot or do not rely on the
rule, are also not subject to the limitation of the 1940 Act on acquiring
interests in other investment companies. In order to be able to rely on the
SEC's interpretation, issuers of these CMOs must be unmanaged, fixed asset
issuers, that (a) invest primarily in mortgage-backed securities, (b) do not
issue redeemable securities, (c) operate under general exemptive orders
exempting them from all provisions of the 1940 Act and (d) are not registered or
regulated under the 1940 Act as investment companies. To the extent that the
Funds select CMOs that cannot rely on the rule or do not meet the above
requirements, the Funds may not invest more than 10% of their assets in all such
entities and may not acquire more than 3% of the voting securities of any single
entity.

     The Funds also may invest in, among other things, parallel pay CMOs,
Planned Amortization Class CMOs ("PAC bonds"), sequential pay CMOs, and floating
rate CMOs. Parallel pay CMOs are structured to provide payments of principal on
each payment date to more than one class. PAC bonds generally require payments
of a specified amount of principal on each payment date. Sequential pay CMOs
generally pay principal to only one class while paying interest to several
classes. Floating rate CMOs are securities whose coupon rate fluctuates
according to some formula related to an existing mortgage index or rate. Typical
indices would include the eleventh district cost- of-funds index, the London
Interbank Offered Rate, one-year Treasury yields, and ten-year Treasury yields.

     ADJUSTABLE RATE MORTGAGE SECURITIES: Adjustable rate mortgage securities
("ARMs") are pass-through securities collateralized by mortgages with adjustable
rather than fixed rates. ARMs eligible for inclusion in a mortgage pool
generally provide for a fixed initial mortgage interest rate for either the
first three, six, twelve, thirteen, 36, or 60 scheduled monthly payments.
Thereafter, the interest rates are subject to periodic adjustment based on
changes to a designated benchmark index.

     The ARMs contain maximum and minimum rates beyond which the mortgage
interest rate may not vary over the lifetime of the security. In addition,
certain ARMs provide for additional limitations on the maximum amount by which
the mortgage interest may be adjusted for any single adjustment period. In the
event that market rates of interest rise more rapidly to levels above that of
the ARM's maximum rate, the ARM's coupon may represent a below market rate of
interest. In these circumstances, the market value of the ARM security will
likely have fallen.

     Some ARMs contain limitations on changes in the required monthly payment.
In the event that a monthly payment is not sufficient to pay the interest
accruing on an ARM, any such excess interest is added to the principal balance
of the mortgage loan, which is repaid through future monthly payments. If the
monthly payment for such an instrument exceeds the sum of the interest accrued
at the applicable mortgage interest rate and the principal payment required at
such point to amortize the outstanding principal balance over the remaining term
of the loan, the excess is then utilized to reduce the outstanding principal
balance of the ARM.

     CMO RESIDUALS: CMO residuals are derivative 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,
homebuilders, mortgage banks, commercial banks, investment banks, and special
purpose entities of the foregoing.

     The cash flow generated by the mortgage assets underlying a series of CMOs
is applied first to make required payments of principal and interest on the CMOs
and second to pay the related administrative expenses of the issuer. The
residual in a CMO structure generally represents the interest in any excess cash
flow remaining after making the foregoing payments. Each payment of such excess
cash flow to a holder of the related CMO residual represents income and/or a
return of capital. The amount of residual cash flow resulting from a CMO will
depend on, among other things, the characteristics of the mortgage assets, the
coupon rate of each class of CMO, prevailing interest rates, the amount of
administrative expenses and the prepayment experience on the mortgage assets. In
part, the yield to maturity on the CMO residuals is extremely sensitive to
prepayments on the related underlying mortgage assets, in the same manner as an
interest-only ("IO") class of stripped mortgage-related securities. See
"Stripped Mortgage- Related Securities" below. In addition, if a series of a CMO
includes a class that bears interest at an adjustable rate, the yield to
maturity on the related CMO residual will also be extremely sensitive to changes
in the level of the index upon which interest rate adjustments are based. As
described below with respect to stripped mortgage-related securities, in certain
circumstances a Fund may fail to recoup its initial investment in a CMO
residual.




                                                                       Page B-10
<PAGE>   50




     CMO residuals are generally purchased and sold by institutional investors
through several investment banking firms acting as brokers or dealers. The CMO
residual market has recently developed and CMO residuals currently may not have
the liquidity of other more established securities trading in other markets.
Transactions in CMO residuals are generally completed only after careful review
of the characteristics of the securities in question. In addition, CMO residuals
may or, pursuant to an exemption therefrom, may not have been registered under
the Securities Act. CMO residuals, whether or not registered under the
Securities Act, may be subject to certain restrictions on transferability, and
may be deemed "illiquid" and subject to a Fund's limitations on investment in
illiquid securities.

     STRIPPED MORTGAGE-RELATED SECURITIES: Stripped mortgage-related securities
("SMRS") are derivative multi- class mortgage securities. SMRS may be 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 entities
of the foregoing.

     SMRS 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 SMRS will have one class receiving some of the interest
and most of the principal from the mortgage assets, while the other class will
receive most of the interest and the remainder of the principal. In the most
extreme case, one class will receive all of the interest, (the "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 a Fund's yield to maturity from these securities. If the
underlying mortgage assets experience greater than anticipated prepayments of
principal, a Fund may fail to fully recoup its initial investment in these
securities even if the security is in one of the highest rating categories.


     Although SMRS are purchased and sold by institutional investors through
several investment banking firms acting as brokers or dealers, these securities
were only recently introduced. As a result, established trading markets have not
yet been fully developed and accordingly, these securities may be deemed
"illiquid" and subject to a Fund's limitations on investment in illiquid
securities. The Funds also may invest in stripped mortgage-backed securities
that are privately issued. These securities will be considered illiquid for
purposes of each Fund's limit on illiquid securities.


     INVERSE FLOATERS: An inverse floater is a debt instrument with a floating
or variable interest rate that moves in the opposite direction to the interest
rate on another security or index level. Changes in the interest rate on the
other security or index inversely affect the residual interest rate paid on the
inverse floater, with the result that the inverse floater's price will be
considerably more volatile than that of a fixed-rate bond. Inverse floaters may
experience gains when interest rates fall and may suffer losses in periods of
rising interest rates. The market for inverse floaters is relatively new.

     TIERED INDEX BONDS: Tiered index bonds are relatively new forms of
mortgage-related securities. The interest rate on a tiered index bond is tied to
a specified index or market rate. So long as this index or market rate is below
a predetermined "strike" rate, the interest rate on the tiered index bond
remains fixed. If, however, the specified index or market rate rises above the
"strike" rate, the interest rate of the tiered index bond will decrease. Thus,
under these circumstances, the interest rate on a tiered index bond, like an
inverse floater, will move in the opposite direction of prevailing interest
rates, with the result that the price of the tiered index bond may be
considerably more volatile than that of a fixed-rate bond.

ASSET-BACKED SECURITIES


     The Funds may invest in securities issued by trusts and special purpose
corporations with principal and interest payouts backed by, or supported by, any
of various types of assets. These assets typically include receivables related
to the purchase of automobiles, credit card loans, and home equity loans. These
securities generally take the form of a structured type of security, including
pass-through, pay-through, and stripped interest payout structures similar to
the CMO structure. Investments in these and other types of asset-backed
securities must be consistent with the investment objectives and policies of the
Funds.


RISK FACTORS RELATING TO INVESTING IN MORTGAGE-RELATED AND ASSET-BACKED
SECURITIES

     The yield characteristics of mortgage-related and asset-backed securities
differ from traditional debt securities. Among the major differences are that
interest and principal payments are made more frequently, usually monthly, and
that principal may be prepaid at any time because the underlying mortgage loans
or other assets generally may be prepaid at any time. As a result, if the Funds
purchase such a security at a premium, a prepayment rate that is faster than
expected will reduce yield to maturity, while a prepayment rate that is slower
than expected will have the opposite effect of increasing yield to maturity.
Alternatively, if the Funds purchase these securities at a discount, faster than
expected prepayments will increase, while slower than expected prepayments will




                                                                       Page B-11
<PAGE>   51




reduce, yield to maturity. The Funds may invest a portion of their assets in
derivative mortgage-related securities which are highly sensitive to changes in
prepayment and interest rates. The Adviser will seek to manage these risks (and
potential benefits) by diversifying its investments in such securities and
through hedging techniques.

     During periods of declining interest rates, prepayment of mortgages
underlying mortgage-related securities can be expected to accelerate.
Accordingly, a Fund's ability to maintain positions in high-yielding
mortgage-related securities will be affected by reductions in the principal
amount of such securities resulting from such prepayments, and its ability to
reinvest the returns of principal at comparable rates is subject to generally
prevailing interest rates at that time. Prepayments may also result in the
realization of capital losses with respect to higher yielding securities that
had been bought at a premium or the loss of opportunity to realize capital gains
in the future from possible future appreciation.

     Asset-backed securities involve certain risks that are not posed by
mortgage-related securities, resulting mainly from the fact that asset-backed
securities do not usually contain the complete benefit of a security interest in
the related collateral. For example, credit card receivables generally are
unsecured and the debtors are entitled to the protection of a number of state
and Federal consumer credit laws, some of which may reduce the ability to obtain
full payment. In the case of automobile receivables, due to various legal and
economic factors, proceeds from repossessed collateral may not always be
sufficient to support payments on these securities.

DERIVATIVE INSTRUMENTS


     In addition to the asset-backed securities and mortgage-related securities
(including tiered index bonds and inverse floaters) which may be purchased by
the Funds, the Funds may utilize (and the ALPHATRAK 500 FUND emphasizes) certain
other financial instruments with performance derived from the performance of an
underlying asset ("derivatives"). The Funds might not employ any of the
strategies described below, and no assurance can be given that any strategy used
will succeed. The Funds may purchase and write call and put options on
securities, securities indices and on foreign currencies, and enter into futures
contracts and use options on futures contracts. The Funds also may enter into
swap agreements with other institutional investors with respect to foreign
currencies, interest rates, and securities indices. The Funds may use these
techniques to hedge against changes in interest rates, foreign currency exchange
rates or securities prices or as part of their overall investment strategies.
Each Fund will maintain designated assets consisting of cash, U.S. Government
securities, equity securities or other liquid, unencumbered assets,
marked-to-market daily (or, as permitted by applicable regulation, enter into
certain offsetting positions), to cover its obligations under options, futures
contracts and swap agreements to avoid leveraging of the Fund. The value of some
derivative investments in which the Funds invest may be particularly sensitive
to changes in prevailing interest rates or securities prices. A Fund's ability
to successfully utilize these instruments may depend in part on the Adviser's
ability to forecast correctly the movement of interest rates and other economic
factors. Should the Adviser incorrectly forecast those factors, and take
positions in derivative instruments contrary to prevailing market trends, the
Funds could lose value and experience substantial volatility.

     The Funds may buy or sell interest rate futures contracts, options on
interest rate futures contracts and options on debt securities for the purpose
of hedging against changes in the value of securities which a Fund owns or
anticipates purchasing due to anticipated changes in interest rates. The Funds
also may engage in currency exchange transactions by means of buying or selling
foreign currency on a spot basis, entering into forward foreign currency
exchange contracts, and buying and selling foreign currency options, futures and
options on futures. Foreign currency exchange transactions may be entered into
for the purpose of hedging against foreign currency exchange risk arising from
the Funds' investment or anticipated investment in securities denominated in
foreign currencies.


     OPTIONS ON SECURITIES AND ON SECURITIES INDEXES: A Fund may purchase put
options on securities to seek to protect holdings in an underlying or related
security against a substantial decline in market value. A Fund may purchase call
options on securities to seek to protect against substantial increases in prices
of securities the Fund intends to purchase pending its ability to invest in such
securities in an orderly manner. A Fund may sell put or call options it has
previously purchased, which could result in a net gain or loss depending on
whether the amount realized on the sale is more or less than the premium and
other transaction costs paid on the put or call option which is sold. A Fund may
write a call or put option only if the option is "covered" by the Fund's holding
a position in the underlying securities or by other means which would permit
immediate satisfaction of the Fund's obligation as writer of the option. Prior
to exercise or expiration, an option may be closed out by an offsetting purchase
or sale of an option of the same series.


                                                                       Page B-12
<PAGE>   52


     The purchase and writing of options involves certain risks. During the
option period, the covered call writer has, in return for the premium on the
option, given up the opportunity to profit from a price increase in the
underlying securities above the sum of the premium and exercise price, but, as
long as its obligation as a writer continues, has retained the risk of loss
should the price of the underlying securities decline. The writer of an option
has no control over the time when it may be required to fulfill its obligation
as a writer of the option. Once an option writer has received an exercise
notice, it cannot effect a closing purchase transaction in order to terminate
its obligation under the option and must deliver the underlying securities at
the exercise price. If a put or call option purchased by the Fund is not sold
when it has remaining value, and if the market price of the underlying security,
in the case of a put, remains equal to or greater than the exercise price or, in
the case of a call, remains less than or equal to the exercise price, the Fund
will lose its entire investment in the option. Also, where a put or call option
on a particular security is purchased to hedge against price movements in a
related security, the price of the put or call option may move more or less than
the price of the related security. There can be no assurance that a liquid
market will exist when a Fund seeks to close out an option position.
Furthermore, if trading restrictions or suspensions are imposed on the options
markets, a Fund may be unable to close out a position.

     RISKS ASSOCIATED WITH OPTIONS ON SECURITIES AND INDEXES. As mentioned
above, there are several risks associated with transactions in options on
securities and on indexes. 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. A decision as to whether, when and how to use options involves
the exercise of skill and judgment, and even a well-conceived transaction may be
unsuccessful to some degree because of market behavior or unexpected events.

     There can be no assurance that a liquid market will exist when a Fund seeks
to close out an option position. If a Fund were unable to close out an option
that it had purchased on a security, it would have to exercise the option in
order to realize any profit or the option may expire worthless. If a Fund were
unable to close out a covered call option that it had written on a security, it
would not be able to sell the underlying security unless the option expired
without exercise.

     If trading were suspended in an option purchased by a Fund, the Fund would
not be able to close out the option. If restrictions on exercise were imposed,
the Fund might be unable to exercise an option it had purchased. Except to the
extent that a call option on an index written by the Fund is covered by an
option on the same index purchased by the Fund, movements in the index may
result in a loss to the Fund; however, such losses may be mitigated by changes
in the value of the Fund's securities during the period the option was
outstanding.

     FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. A Fund may use interest
rate, foreign currency or index futures contracts, as specified for that Fund in
the Prospectus. An interest rate, foreign currency or index futures contract
provides for the future sale by one party and purchase by another party of a
specified quantity of a financial instrument, foreign currency or the cash value
of an index at a specified price and time. A futures contract on an index is an
agreement pursuant to which two parties agree to take or make delivery of an
amount of cash equal to the difference between the value of the index at the
close of the last trading day of the contract and the price at which the index
contract was originally written. Although the value of an index might be a
function of the value of certain specified securities, no physical delivery of
these securities is made. A public market exists in futures contracts covering a
number of indexes as well as financial instruments and foreign currencies,
including: the S&P 500; the S&P 100; the S&P Midcap 400; the Nikkei 225; the
NYSE composite; U.S. Treasury bonds; U.S. Treasury notes; GNMA Certificates;
three-month U.S. Treasury bills; 90-day commercial paper; bank certificates of
deposit; Eurodollar certificates of deposit; the Australian dollar; the Canadian
dollar; the British pound; the German mark; the Japanese yen; the French franc;
the Swiss franc; the Mexican peso; and certain multinational currencies, such as
the European Currency Unit ("ECU"). It is expected that other futures contracts
will be developed and traded in the future.

     A Fund may purchase and write call and put futures options. Futures options
possess many of the same characteristics as options on securities and indexes
(discussed above). A futures option gives the holder the right, in return for
the premium paid, to assume a long position (call) or short position (put) in a
futures contract at a specified exercise price at any time during the period of
the option. Upon exercise of a call option, the holder acquires a long position
in the futures contract and the writer is assigned the opposite short position.
In the case of a put option, the opposite is true.

     Each Fund will use futures contracts and options on futures contracts in
accordance with the applicable rules of the CFTC under which the Trust and the
Funds avoid being deemed a "commodity pool" and the Adviser being deemed a
"commodity pool operator." Accordingly, each Fund intends generally to limit its
use of futures contracts and futures options as described below under
"Limitations on Use of Futures and Futures Options."

     Except for the ALPHATRAK 500 FUND, the Funds generally will use futures for
hedging purposes only. The ALPHATRAK 500 FUND uses futures in an effort to
achieve total return greater than the S&P 500 Index, as described in the
Prospectus. With respect to



                                                                       Page B-13
<PAGE>   53

hedging transactions, for example, a Fund might use futures contracts to hedge
against anticipated changes in interest rates that might adversely affect either
the value of the Fund's securities or the price of the securities which the Fund
intends to purchase. A Fund's hedging activities may include sales of futures
contracts as an offset against the effect of expected increases in interest
rates, and purchases of futures contracts as an offset against the effect of
expected declines in interest rates. Although other techniques could be used to
reduce a Fund's exposure to interest rate fluctuations, the Fund may be able to
hedge its exposure more effectively and perhaps at a lower cost by using futures
contracts and futures options.

         A Fund will only enter into futures contracts and futures options that
are standardized and traded on a U.S. or foreign exchange, board of trade, or
similar entity, or quoted on an automated quotation system.

         When a purchase or sale of a futures contract is made by a Fund, the
Fund is required to deposit with its custodian (or broker, if legally permitted)
a specified amount of assets determined to be liquid by the Adviser in
accordance with procedures established by the Board of Trustees ("initial
margin"). The margin required for a futures contract is set by the exchange on
which the contract is traded and may be modified during the term of the
contract. Margin requirements on foreign exchanges may be different than U.S.
exchanges. The initial margin is in the nature of a performance bond or good
faith deposit on the futures contract which is returned to the Fund upon
termination of the contract, assuming all contractual obligations have been
satisfied. Each Fund expects to earn interest income on its initial margin
deposits. A futures contract held by a Fund is valued daily at the official
settlement price of the exchange on which it is traded. Each day the Fund pays
or receives cash, called "variation margin," equal to the daily change in value
of the futures contract. This process is known as "marking to market." Variation
margin does not represent a borrowing or loan by a Fund but is instead a
settlement between the Fund and the broker of the amount one would owe the other
if the futures contract expired. In computing daily net asset value, each Fund
will mark to market its open futures positions.

         A Fund is also required to deposit and maintain margin with respect to
put and call options on futures contracts written by it. Such margin deposits
will vary depending on the nature of the underlying futures contract (and the
related initial margin requirements), the current market value of the option,
and other futures positions held by the Fund.

         Although some futures contracts call for making or taking delivery of
the underlying securities, generally these obligations are closed out prior to
delivery by offsetting purchases or sales of matching futures contracts (same
exchange, underlying security or index, and delivery month). If an offsetting
purchase price is less than the original sale price, the Fund realizes a capital
gain, or if it is more, the Fund realizes a capital loss. Conversely, if an
offsetting sale price is more than the original purchase price, the Fund
realizes a capital gain, or if it is less, the Fund realizes a capital loss. The
transaction costs must also be included in these calculations.

         The Funds may write covered straddles consisting of a call and a put
written on the same underlying futures contract. A straddle will be covered when
sufficient assets are deposited to meet the Funds' immediate obligations. A Fund
may use the same liquid assets to cover both the call and put options where the
exercise price of the call and put are the same, or the exercise price of the
call is higher than that of the put. In such cases, the Funds will also
designate liquid assets equivalent to the amount, if any, by which the put is
"in the money."


         LIMITATIONS ON USE OF FUTURES AND FUTURES OPTIONS. Except for the
ALPHATRAK 500 FUND, the Funds generally will enter into positions in futures
contracts and related options only for "bona fide hedging" purposes. With
respect to positions in futures and related options that do not constitute bona
fide hedging positions, a Fund will not enter into a futures contract or futures
option contract if, immediately thereafter, the aggregate initial margin
deposits relating to such positions plus premiums paid by it for open futures
option positions, less the amount by which any such options are "in-the-money,"
would exceed 5% of the Fund's net assets. A call option is "in-the-money" if the
value of the futures contract that is the subject of the option exceeds the
exercise price. A put option is "in-the-money" if the exercise price exceeds the
value of the futures contract that is the subject of the option. There is no
other percentage limitation on a Fund's use of options, futures and options
thereon, except for the limitation on foreign currency option contracts
described below.


         When purchasing a futures contract, a Fund will designate (and
mark-to-market on a daily basis) assets determined to be liquid by the Adviser
in accordance with procedures established by the Board of Trustees, that, when
added to the amounts deposited with a futures commission merchant as margin, are
equal to the market value of the futures contract. Alternatively, the Fund may
"cover" its position by purchasing a put option on the same futures contract
with a strike price as high or higher than the price of the contract held by the
Fund.

         When selling a futures contract, a Fund will designate (and
mark-to-market on a daily basis) assets determined to be liquid by the Adviser
in accordance with procedures established by the Board of Trustees, that are
equal to the market value of the instruments underlying the contract.
Alternatively, the Fund may "cover" its position by owning the instruments
underlying the




                                                                       Page B-14

contract (or, in the case of an index futures contract, a portfolio with a
volatility substantially similar to that of the index on which the futures
contract is based), or by holding a call option permitting the Fund to purchase
the same futures contract at a price no higher than the price of the contract
written by the Fund (or at a higher price if the difference is maintained in
liquid assets with the Trust's custodian).

         When selling a call option on a futures contract, a Fund will maintain
with its custodian (and mark-to-market on a daily basis) assets determined to be
liquid by the Adviser in accordance with procedures established by the Board of
Trustees, that, when added to the amounts deposited with a futures commission
merchant as margin, equal the total market value of the futures contract
underlying the call option. Alternatively, the Fund may cover its position by
entering into a long position in the same futures contract at a price no higher
than the strike price of the call option, by owning the instruments underlying
the futures contract, or by holding a separate call option permitting the Fund
to purchase the same futures contract at a price not higher than the strike
price of the call option sold by the Fund.

         When selling a put option on a futures contract, a Fund will maintain
with its custodian (and mark-to-market on a daily basis) assets determined to be
liquid by the Adviser in accordance with procedures established by the Board of
Trustees, that equal the purchase price of the futures contract, less any margin
on deposit. Alternatively, the Fund may cover the position either by entering
into a short position in the same futures contract, or by owning a separate put
option permitting it to sell the same futures contract so long as the strike
price of the purchased put option is the same or higher than the strike price of
the put option sold by the Fund.

         To the extent that securities with maturities greater than one year are
used to establish and collateralize or cover a Fund's obligations under futures
contracts and related options, such use will not eliminate the risk of a form of
leverage, which may tend to exaggerate the effect on net asset value of any
increase or decrease in the market value of a Fund's portfolio, and may require
liquidation of portfolio positions when it is not advantageous to do so.
However, any potential risk of leverage resulting from the use of securities
with maturities greater than one year may be mitigated by the overall duration
limit on a Fund's portfolio securities. Thus, the use of a longer-term security
may require a Fund to hold offsetting short-term securities to balance the
Fund's portfolio such that the Fund's duration does not exceed the maximum
permitted for the Fund in the Prospectus.

         The requirements for qualification as a regulated investment company
also may limit the extent to which a Fund may enter into futures, futures
options or forward contracts. See "Dividends and Tax Status."

         RISKS ASSOCIATED WITH FUTURES AND FUTURES OPTIONS. There are several
risks associated with the use of futures contracts and futures options as
hedging techniques. A purchase or sale of a futures contract may result in
losses in excess of the amount invested in the futures contract. There can be no
guarantee that there will be a correlation between price movements in the
hedging vehicle and in the Fund securities being hedged. In addition, there are
significant differences between the securities and futures markets that could
result in an imperfect correlation between the markets, causing a given hedge
not to achieve its objectives. The degree of imperfection of correlation depends
on circumstances such as variations in speculative market demand for futures and
futures options on securities, including technical influences in futures trading
and futures options, and differences between the financial instruments being
hedged and the instruments underlying the standard contracts available for
trading in such respects as interest rate levels, maturities. and
creditworthiness of issuers. A decision as to whether, when and how to hedge
involves the exercise of skill and judgment, and even a well-conceived hedge may
be unsuccessful to some degree because of market behavior or unexpected interest
rate trends.

         Futures exchanges may limit the amount of fluctuation permitted in
certain 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 the
current trading session. Once the daily limit has been reached in a futures
contract subject to the limit, no more trades may be made on that day at a price
beyond that limit. The daily limit governs only price movements during a
particular trading day and therefore does not limit potential losses because the
limit may work to prevent the liquidation of unfavorable positions. For example,
futures prices have occasionally moved to the daily limit for several
consecutive trading days with little or no trading, thereby preventing prompt
liquidation of positions and subjecting some holders of futures contracts to
substantial losses.

         There can be no assurance that a liquid market will exist at a time
when a Fund seeks to close out a futures contract or a futures option position,
and that Fund would remain obligated to meet margin requirements until the
position is closed. In addition, many of the contracts discussed above are
relatively new instruments without a significant trading history. As a result,
there can be no assurance that an active secondary market will develop or
continue to exist.




                                                                       Page B-15

<PAGE>   55

         ADDITIONAL RISKS OF OPTIONS ON SECURITIES, FUTURES CONTRACTS, OPTIONS
ON FUTURES CONTRACTS, AND FORWARD CURRENCY EXCHANGE CONTRACTS AND OPTIONS
THEREON. Options on securities, futures contracts, options on futures contracts,
and options on currencies may be traded on foreign exchanges. Such transactions
may not be regulated as effectively as similar transactions in the United
States; may not involve a clearing mechanism and related guarantees, and are
subject to the risk of governmental actions affecting trading in, or the prices
of, foreign securities. The value of such positions also could be adversely
affected by (i) other complex foreign political, legal and economic factors,
(ii) lesser availability than in the United States of data on which to make
trading decisions, (iii) delays in the Trust's ability to act upon economic
events occurring in foreign markets during non-business hours in the United
States, (iv) the imposition of different exercise and settlement terms and
procedures and margin requirements than in the United States, and (v) lesser
trading volume.

         SWAP AGREEMENTS. The Funds may enter into interest rate, index and
currency exchange rate swap agreements. These transactions are entered into in a
attempt to obtain a particular return when it is considered desirable to do so,
possibly at a lower cost to a Fund than if the Fund had invested directly in an
instrument that yielded that desired return. Swap agreements are two-party
contracts entered into primarily by institutional investors for periods ranging
from a few weeks to more than one year. In a standard "swap" transaction, two
parties agree to exchange the returns (or differentials in rates of return)
earned or realized on particular predetermined investments or instruments, which
may be adjusted for an interest factor. The gross returns to be exchanged or
"swapped" between the parties are generally calculated with respect to a
"notional amount," i.e., the return on or increase in value of a particular
dollar amount invested at a particular interest rate, in a particular foreign
currency, or in a "basket" of securities representing a particular index. Forms
of swap agreements include interest rate caps, under which, in return for a
premium, one party agrees to make payments to the other to the extent that
interest rates exceed a specified rate, or "cap"; interest rate floors, under
which, in return for a premium, one party agrees to make payments to the other
to the extent that interest rates fall below a specified rate, or "floor"; and
interest rate collars, under which a party sells a cap and purchases a floor or
vice versa in an attempt to protect itself against interest rate movements
exceeding given minimum or maximum levels.


         Most swap agreements entered into by the Funds would calculate the
obligations of the parties to the agreement on a "net basis." Consequently, a
Fund's current obligations (or rights) under a swap agreement will generally be
equal only to the net amount to be paid or received under the agreement based on
the relative values of the positions held by each party to the agreement (the
"net amount"). A Fund's current obligations under a swap agreement will be
accrued daily (offset against any amounts owing to the Fund) and any accrued but
unpaid net amounts owed to a swap counterparty will be covered by the
maintenance of a designated account consisting of assets determined to be liquid
by the Adviser in accordance with procedures established by the Board of
Trustees, to avoid any potential leveraging of the Fund's portfolio. Obligations
under swap agreements so covered will not be construed to be "senior securities"
for purposes of the Fund's investment restriction concerning senior securities.
Swap agreements are subject to the Funds' overall limit that no more than 15% of
net assets may be invested in illiquid securities, and a Fund will not enter
into a swap agreement with any single party if the net amount owed or to be
received under existing contracts with that party would exceed 5% of the Fund's
assets.


         Whether a Fund's use of swap agreements will be successful in
furthering its investment objectives will depend on the Adviser's ability to
predict correctly whether certain types of investments are likely to produce
greater returns than other investments. Because they are two party contracts and
because they may have terms of greater than seven days, swap agreements may be
considered to be illiquid. Moreover, a Fund bears the risk of loss of the amount
expected to be received under a swap agreement in the event of the default or
bankruptcy of a swap agreement counterparty. The Funds will enter into swap
agreements only with counterparties that meet certain standards of
creditworthiness (generally, such counterparties would have to be eligible
counterparties under the terms of the Funds' repurchase agreement guidelines).
Certain restrictions imposed on the Funds by the Internal Revenue Code of 1986,
as amended (the "Code") may limit the Funds' ability to use swap agreements. The
swaps market is a relatively new market and is largely unregulated. It is
possible that developments in the swaps market, including potential government
regulation, could adversely affect a Fund's ability to terminate existing swap
agreements or to realize amounts to be received under such agreements.

         Certain swap agreements are exempt from most provisions of the
Commodity Exchange Act ("CEA") and, therefore, are not regulated as futures or
commodity option transactions under the CEA, pursuant to regulations approved by
the CFTC. To qualify for this exemption, a swap agreement must be entered into
by "eligible participants," which includes the following, provided the
participants' total assets exceed established levels: a bank or trust company,
savings association or credit union, insurance company, investment company
subject to regulation under the 1940 Act, commodity pool, corporation,
partnership, proprietorship, organization, trust or other entity, employee
benefit plan, governmental entity, broker-dealer, futures commission merchant,
natural person, or regulated foreign person. To be eligible, natural persons and
most other entities must have total assets exceeding $10 million; commodity
pools and employee benefit plans must have assets exceeding $5 million. In
addition, an eligible swap transaction must meet three conditions. First, the
swap agreement may not be part of a fungible class of agreements that are
standardized as to their



                                                                       Page B-16
<PAGE>   56

material economic terms. Second, the creditworthiness of parties with actual or
potential obligations under the swap agreements must be a material consideration
in entering into or determining the terms of the swap agreement, including
pricing, cost or credit enhancement terms. Third, swap agreements may not be
entered into and traded on or through a multilateral transaction execution
facility.

         This exemption is not exclusive, and participants may continue to rely
on existing exclusions for swaps, such as the Policy Statement issued in July
1989 which recognized a safe harbor for swap transactions from regulation as
futures or commodity option transactions under the CEA or its regulations. The
Policy Statement applies to swap transactions settled in cash that (1) have
individually tailored terms, (2) lack exchange-style offset and the use of a
clearing organization or margin system, (3) are undertaken in conjunction with a
line of business, and (4) are not marketed to the public.

         STRUCTURED NOTES. Structured notes are derivative debt securities, the
interest rate or principal of which is determined by an unrelated indicator.
Indexed securities include structured notes as well as securities other than
debt securities, the interest rate or principal of which is determined by an
unrelated indicator. Indexed securities may include a multiplier that multiplies
the indexed element by a specified factor and, therefore, the value of such
securities may be very volatile. To the extent a Fund invests in these
securities, however, the Adviser analyzes these securities in its overall
assessment of the effective duration of the Fund's portfolio in an effort to
monitor the Fund's interest rate risk.


         FOREIGN CURRENCY OPTIONS AND RELATED RISKS: The Funds may take
positions in options on foreign currencies to hedge against the risk of foreign
exchange rate fluctuations on foreign securities the Funds hold in their
portfolios or intend to purchase. For example, if a Fund were to enter into a
contract to purchase securities denominated in a foreign currency, it could
effectively fix the maximum U.S. dollar cost of the securities by purchasing
call options on that foreign currency. Similarly, if a Fund held securities
denominated in a foreign currency and anticipated a decline in the value of that
currency against the U.S. dollar, it could hedge against such a decline by
purchasing a put option on the currency involved. The markets in foreign
currency options are relatively new, and a Fund's ability to establish and close
out positions in such options is subject to the maintenance of a liquid
secondary market. There can be no assurance that a liquid secondary market will
exist for a particular option at any specific time. In addition, options on
foreign currencies are affected by all of those factors that influence foreign
exchange rates and investments generally.

         No Fund will enter into foreign currency option contracts if the
premiums on such options exceed 5% of the Fund's total assets.


                  The quantities of currencies underlying option contracts
represent odd lots in a market dominated by transactions between banks, and as a
result extra transaction costs may be incurred upon exercise of an option.

                  There is no systematic reporting of last sale information for
foreign currencies or any regulatory requirement that quotations be firm or
revised on a timely basis. Quotation information is generally representative of
very large transactions in the interbank market and may not reflect smaller
transactions where rates may be less favorable. Option markets may be closed
while round-the-clock interbank currency markets are open, and this can create
price and rate discrepancies.

                  RISKS OF OPTIONS TRADING: The Funds may effectively terminate
their rights or obligations under options by entering into closing transactions.
Closing transactions permit a Fund to realize profits or limit losses on its
options positions prior to the exercise or expiration of the option. The value
of a foreign currency option depends on the value of the underlying currency
relative to the U.S. dollar. Other factors affecting the value of an option are
the time remaining until expiration, the relationship of the exercise price to
market price, the historical price volatility of the underlying currency and
general market conditions. As a result, changes in the value of an option
position may have no relationship to the investment merit of a foreign security.
Whether a profit or loss is realized on a closing transaction depends on the
price movement of the underlying currency and the market value of the option.

                  Options normally have expiration dates of up to nine months.
The exercise price may be below, equal to or above the current market value of
the underlying currency. Options that expire unexercised have no value, and a
Fund will realize a loss of any premium paid and any transaction costs. Closing
transactions may be effected only by negotiating directly with the other party
to the option contract, unless a secondary market for the options develops.
Although the Funds intend to enter into foreign currency options only with
dealers which agree to enter into, and which are expected to be capable of
entering into, closing transactions with the Funds, there can be no assurance
that a Fund will be able to liquidate an option at a favorable price at any time
prior to expiration. In the event of insolvency of the counter-party, a Fund may
be unable to liquidate a foreign currency option. Accordingly, it may not be
possible to effect closing transactions with respect to certain options, with
the result that a Fund would have to exercise those options that it had
purchased in order to realize any profit.


                                                                       Page B-17
<PAGE>   57

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS: The Funds may use forward contracts
to protect against uncertainty in the level of future exchange rates. The Funds
will not speculate with forward contracts or foreign currency exchange rates.

         A Fund may enter into forward contracts with respect to specific
transactions. For example, when a Fund enters into a contract for the purchase
or sale of a security denominated in a foreign currency, or when a Fund
anticipates the receipt in a foreign currency of dividend or interest payments
on a security that it holds, the Fund may desire to "lock" in the U.S. dollar
price of the security or the U.S. dollar equivalent of the payment, by entering
into a forward contract for the purchase or sale, for a fixed amount of U.S.
dollars or foreign currency, of the amount of foreign currency involved in the
underlying transaction. A Fund will thereby be able to protect itself against a
possible loss resulting from an adverse change in the relationship between the
currency exchange rates during the period between the date on which the security
is purchased or sold, or on which the payment is declared, and the date on which
such payments are made or received.

         A Fund also may use forward contracts in connection with portfolio
positions to lock in the U.S. dollar value of those positions, to increase the
Fund's exposure to foreign currencies that the Adviser believes may rise in
value relative to the U.S. dollar or to shift the Fund's exposure to foreign
currency fluctuations from one country to another. For example, when the Adviser
believes that the currency of a particular foreign country may suffer a
substantial decline relative to the U.S. dollar or another currency, it may
enter into a forward contract to sell the amount of the former foreign currency
approximating the value of some or all of the Funds' portfolio securities
denominated in such foreign currency. This investment practice generally is
referred to as "cross-hedging" when another foreign currency is used.

         The precise matching of the forward contract amounts and the value of
the securities involved will not generally be possible because the future value
of such securities in foreign currencies will change as a consequence of market
movements in the value of those securities between the date the forward contract
is entered into and the date it matures. Accordingly, it may be necessary for a
Fund to purchase additional foreign currency on the spot (i.e., cash) market
(and bear the expense of such purchase) if the market value of the security is
less than the amount of foreign currency the Fund is obligated to deliver and if
a decision is made to sell the security and make delivery of the foreign
currency. Conversely, it may be necessary to sell on the spot market some of the
foreign currency received upon the sale of the portfolio security if its market
value exceeds the amount of foreign currency the Fund is obligated to deliver.
The projection of short-term currency market movements is extremely difficult,
and the successful execution of a short-term hedging strategy is highly
uncertain. Forward contracts involve the risk that anticipated currency
movements will not be accurately predicted, causing the Fund to sustain losses
on these contracts and transaction costs. A Fund may enter into forward
contracts or maintain a net exposure to such contracts only if (1) the
consummation of the contracts would not obligate the Fund to deliver an amount
of foreign currency in excess of the value of the Fund's portfolio securities or
other assets denominated in that currency or (2) the Fund designates liquid
assets in an amount not less than the value of the Fund's total assets committed
to the consummation of the contracts. Under normal circumstances, consideration
of the prospect for currency parities will be incorporated into the longer term
investment decisions made with regard to overall diversification strategies.
However, the Adviser believes it is important to have the flexibility to enter
into such forward contracts when it determines that the best interests of a Fund
will be served.

         At or before the maturity date of a forward contract that requires a
Fund to sell a currency, the Fund may either sell a portfolio security and use
the sale proceeds to make delivery of the currency or retain the security and
offset its contractual obligation to deliver the currency by purchasing a second
contract pursuant to which the Fund will obtain, on the same maturity date, the
same amount of the currency that it is obligated to deliver. Similarly, a Fund
may close out a forward contract requiring it to purchase a specified currency
by entering into a second contract entitling it to sell the same amount of the
same currency on the maturity date of the first contract. The Fund would realize
a gain or loss as a result of entering into such an offsetting forward contract
under either circumstance to the extent the exchange rate between the currencies
involved moved between the execution dates of the first and second contracts.

         The cost to the Fund of engaging in forward contracts varies with
factors such as the currencies involved, the length of the contract period and
the market conditions then prevailing. Because forward contracts are usually
entered into on a principal basis, no fees or commissions are involved. The use
of forward contracts does not eliminate fluctuations in the prices of the
underlying securities the Fund owns or intends to acquire, but it does fix a
rate of exchange in advance. In addition, although forward contracts limit the
risk of loss due to a decline in the value of the hedged currencies, at the same
time they limit any potential gain that might result should the value of the
currencies increase.

         Although the Funds value their assets daily in terms of U.S. dollars,
they do not intend to convert holdings of foreign currencies into U.S. dollars
on a daily basis. The Funds may convert foreign currency from time to time, and
investors should be aware of the costs of currency conversion. Although foreign
exchange dealers do not charge a fee for conversion, they do realize a



                                   Page B-18
<PAGE>   58

profit based on the difference between the prices at which they are buying and
selling various currencies. Thus, a dealer may offer to sell a foreign currency
to a Fund at one rate, while offering a lesser rate of exchange should the Fund
desire to resell that currency to the dealer.


FOREIGN SECURITIES

         Each Fund has the right to invest in foreign securities. Foreign
economies may differ from the U.S. economy; individual foreign companies may
differ from domestic companies in the same industry; and foreign currencies may
be stronger or weaker than the U.S. dollar. The Adviser believes that the
ability to invest abroad will enable the Funds to take advantage of these
differences when they are favorable.

         Fixed-income securities that may be purchased by the Funds include debt
obligations issued or guaranteed by foreign governments, their subdivisions,
agencies or instrumentalities, or by supranational entities that have been
constituted by the governments of several countries to promote economic
development, such as The World Bank and The Asian Development Bank. Foreign
investment in certain foreign government debt is restricted or controlled to
varying degrees.

         The Funds may also invest in fixed-income securities of issuers located
in emerging foreign markets. Emerging markets generally include every country in
the world other than the United States, Canada, Japan, Australia, Malaysia, New
Zealand, Hong Kong, Singapore and most Western European countries. In
determining what countries constitute emerging markets, the Adviser will
consider, among other things, data, analysis and classification of countries
published or disseminated by the International Bank for Reconstruction and
Development (the "World Bank") and the International Financial Corporation.
Currently, investing in many emerging markets may not be desirable or feasible,
because of the lack of adequate custody arrangements for a Fund's assets, overly
burdensome repatriation and similar restrictions, the lack of organized and
liquid securities markets, unacceptable political risks or other reasons. As
opportunities to invest in securities in emerging markets develop, the Funds
expect to expand and further broaden the group of emerging markets in which they
invest.

         From time to time, emerging markets have offered the opportunity for
higher returns in exchange for a higher level of risk. Accordingly, the Adviser
believes that each Fund's ability to invest in emerging markets throughout the
world may enable the achievement of results superior to those produced by funds,
with similar objectives to those of the Funds, that invest solely in securities
in developed markets. There is no assurance that any Fund will achieve these
results.

         The Funds may invest in the following types of emerging market
fixed-income securities: (a) fixed-income securities issued or guaranteed by
governments, their agencies, instrumentalities or political subdivisions, or by
government-owned, controlled or sponsored entities, including central banks
(collectively, "Sovereign Debt"), including Brady Bonds (described below); (b)
interests in issuers organized and operated for the purpose of restructuring the
investment characteristics of Sovereign Debt; (c) fixed-income securities issued
by banks and other business entities; and (d) fixed-income securities
denominated in or indexed to the currencies of emerging markets. Fixed-income
securities held by the Funds may take the form of bonds, notes, bills,
debentures, bank debt obligations, short-term paper, loan participations,
assignments and interests issued by entities organized and operated for the
purpose of restructuring the investment characteristics of any of the foregoing.
There is no requirement with respect to the maturity of fixed-income securities
in which the Funds may invest.

         The Funds may invest in Brady Bonds and other Sovereign Debt of
countries that have restructured or are in the process of restructuring
Sovereign Debt pursuant to the Brady Plan. "Brady Bonds" are debt securities
issued under the framework of the Brady Plan, an initiative announced by former
U.S. Treasury Secretary Nicholas F. Brady in 1989 as a mechanism for debtor
nations to restructure their outstanding external commercial bank indebtedness.
In restructuring its external debt under the Brady Plan framework, a debtor
nation negotiates with its existing bank lenders as well as multilateral
institutions such as the World Bank and the International Monetary Fund ("IMF").
The Brady Plan framework, as it has developed, contemplates the exchange of
commercial bank debt for newly issued Brady Bonds. Brady Bonds may also be
issued in respect of new money being advanced by existing lenders in connection
with the debt restructuring. The World Bank and/or the IMF support the
restructuring by providing funds pursuant to loan agreements or other agreements
which enable the debtor nation to collateralize the new Brady Bonds or to
repurchase outstanding bank debt at a discount.

         Emerging market fixed-income securities generally are considered to be
of a credit quality below investment grade, even though they often are not rated
by any nationally recognized statistical rating organizations. Investment in
emerging market fixed-income securities will be allocated among various
countries based upon the Adviser's analysis of credit risk and its consideration
of a number of factors, including: prospects for relative economic growth among
the different countries in which the Funds may invest; expected levels of
inflation; government policies influencing business conditions; the outlook for
currency




                                                                       Page B-19
<PAGE>   59


relationships; and the range of the individual investment opportunities
available to international investors. The Adviser's emerging market sovereign
credit analysis includes an evaluation of the issuing country's total debt
levels, currency reserve levels, net exports/imports, overall economic growth,
level of inflation, currency fluctuation, political and social climate and
payment history. Particular fixed-income securities will be selected based upon
credit risk analysis of potential issuers, the characteristics of the security
and interest rate sensitivity of the various debt issues available with respect
to a particular issuer, analysis of the anticipated volatility and liquidity of
the particular debt instruments, and the tax implications to the Fund. The
emerging market fixed-income securities in which the Funds may invest are not
subject to any minimum credit quality standards.


RISK FACTORS RELATING TO INVESTING IN HIGH-YIELD SECURITIES

         Lower-rated or unrated (i.e. high-yield) securities are more likely to
react to developments affecting market risk (such as interest rate sensitivity,
market perception of creditworthiness of the issuer and general market
liquidity) and credit risk (such as the issuer's inability to meet its
obligations) than are more highly rated securities, which react primarily to
movements in the general level of interest rates. The Adviser considers both
credit risk and market risk in making investment decisions for the Funds.
Investors should carefully consider the relative risk of investing in high-yield
securities and understand that such securities are not generally meant for
short-term trading.

         The amount of high-yield securities outstanding proliferated in the
1980's in conjunction with the increase in merger and acquisition and leveraged
buyout activity. Under adverse economic conditions, there is a risk that highly
leveraged issuers may be unable to service their debt obligations upon maturity.
In addition, the secondary market for high-yield securities, which is
concentrated in relatively few market makers, may not be as liquid as the
secondary market for more highly rated securities. Under adverse market or
economic conditions, the secondary market for high-yield securities could
contract further, independent of any specific adverse changes in the condition
of a particular issuer. As a result, the Adviser could find it more difficult to
sell these securities or may be able to sell the securities only at prices lower
than if such securities were widely traded. Prices realized upon the sale of
such lower-rated or unrated securities, under these circumstances, may be less
than the prices used in calculating the Funds' net asset value.

         Lower-rated or unrated debt obligations present risks based on payment
expectations. If an issuer calls the obligation for redemption, a Fund may have
to replace the security with a lower yielding security, resulting in a decreased
return for investors. If a Fund experiences unexpected net redemptions, it may
be forced to sell its higher- rated securities, resulting in a decline in the
overall credit quality of the Fund's portfolio and increasing the exposure of
the Fund to the risks of high-yield securities.

ILLIQUID SECURITIES

         A Fund may not invest more than 15% of its net assets in repurchase
agreements which have a maturity of longer than seven days or in other illiquid
securities, including securities that are illiquid by virtue of the absence of a
readily available market (either within or outside of the United States) or
legal or contractual restrictions of resale. Historically, illiquid securities
have included securities subject to contractual or legal restrictions on resale
because they have not been registered under the Securities Act, securities which
are otherwise not readily marketable and repurchase agreements have a maturity
of longer than seven days. Securities which have not been registered under the
Securities Act are referred to as private placements or restricted securities
and are purchased directly from the issuer or in the secondary market. Mutual
funds do not typically hold a significant amount of these restricted or other
illiquid securities because of the potential for delays on resale and
uncertainty in valuation. Limitations on resale may have an adverse effect on
the marketability of portfolio securities and a mutual fund might be unable to
dispose of restricted or other illegal securities promptly or at reasonable
prices and might thereby experience difficulty satisfying redemptions within
seven days. A mutual fund might also have to register such restricted securities
in order to dispose of them resulting in additional expense and delay. Adverse
market conditions could impede such a public offering of securities. Currently
the Funds may invest in securities issued in private placements.

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

         Rule 144A under the Securities Act allows for a broader institutional
trading market for securities otherwise subject to restriction on resale to the
general public. Rule 144A established a "safe harbor" from the registration
requirements of the Securities Act for resales of certain securities to
qualified institutional buyers. The Adviser anticipates that the market for
certain restricted


                                                                       Page B-20

securities such as institutional commercial paper and foreign securities will
expand further as a result of this rule and the development of automated systems
for the trading, clearance and settlement of unregistered securities of domestic
and foreign issuers, such as the PORTAL System sponsored by the National
Association of Securities Dealers, Inc.

         Restricted securities eligible for resale pursuant to Rule 144A under
the Securities Act and commercial paper for which there is a readily available
market will not be deemed to be illiquid. The Adviser will monitor the liquidity
of such restricted securities subject to the supervision of the Trustees. In
reaching liquidity decisions, the Adviser will consider, inter alia, the
following factors: (1) the frequency of trades and quotes for the security; (2)
the number of dealers wishing to purchase or sell the security and the number of
other potential purchasers; (3) dealer undertakings to make a market in the
security; and (4) the nature of the security and the nature of the marketplace
trades (e.g. the time needed to dispose of the security, the method of
soliciting offers and the mechanics of the transfer). In addition, in order for
commercial paper that is issued in reliance on Section 4(2) of the Securities
Act to be considered liquid, (i) it must be rated in one or two of the highest
rating categories by at least two nationally recognized statistical rating
organizations ("NRSRO"), or if only one NRSRO rates the securities, by that
NRSRO, or, if unrated, be of comparable quality in the view of the Adviser, and
(ii) it must not be "traded flat" (i.e., without accrued interest) or in default
as to principal or interest. Investing in Rule 144A securities could have the
effect of increasing the level of Fund illiquidity to the extent that qualified
institutional buyers become, for a time, uninterested in purchasing these
securities. Repurchase agreements subject to demand are deemed to have a
maturity equal to the notice period.


BORROWING

         Each Fund may borrow for temporary, emergency or investment purposes up
to 10% of its total assets. This borrowing may be unsecured. Borrowing subjects
a Fund to interest costs which may or may not be recovered by appreciation of
the securities purchased, and can exaggerate the effect on net asset value of
any increase or decrease in the market value of a Fund's portfolio. This is the
speculative factor known as leverage.

* "Interested" Trustee, as defined in the 1940 Act, due to the relationship
indicated with the Adviser.


         The Trust does not pay salaries to any of its officers or fees to any
of its Trustees who are affiliated with the Adviser. Disinterested Trustees
received an annual retainer of $3,000 and $1,500 for each meeting of the Board
of Trustees attended for the fiscal year ended March 31, 1999. For the fiscal
year ended March 31, 2000, the disinterested Trustees will be paid a retainer of
$6,000 and $1,500 for each meeting of the Board of Trustees attended. Mr. Holmes
will also be compensated according to that schedule. Mr. Holmes is not a
disinterested Trustee because he provides legal services to the Adviser and its
affiliates.

PORTFOLIO TRANSACTIONS AND BROKERAGE

         The Investment Advisory Agreement states that in connection with its
duties to arrange for the purchase and sale of securities held in the portfolio
of each Fund by placing purchase and sale orders for that Fund, the Adviser
shall select such broker-dealers ("brokers") as shall, in the Adviser's
judgment, implement the policy of the Trust to achieve "best execution", i.e.,
prompt and efficient execution at the most favorable securities price. In making
such selection, the Adviser is authorized in the Agreement to consider the
reliability, integrity and financial condition of the broker.

         The Adviser is also authorized by the Agreement to consider whether the
broker provides brokerage and/or research services to the Funds and/or other
accounts of the Adviser. The Agreement states that the commissions paid to
brokers may be higher than another broker would have charged if a good faith
determination is made by the Adviser that the commission is reasonable in
relation to the services provided, viewed in terms of either that particular
transaction or the Adviser's overall responsibilities as to the accounts as to
which it exercises investment discretion and that the Adviser shall use its
judgment in determining that the amount of commissions paid are reasonable in
relation to the value of brokerage and research services provided and need not
place or attempt to place a specific dollar value on such services or on the
portion of commission rates reflecting such services. The Agreement provides
that to demonstrate that such determinations were in good faith, and to show the
overall reasonableness of commissions paid, the Adviser shall be prepared to
show that commissions paid (i) were for purposes contemplated by the Agreement;
(ii) were for products or services which provide lawful and appropriate
assistance to the Adviser's decision-making process; and (iii) were within a
reasonable range as compared to the rates charged by brokers to other
institutional investors as such rates may become known from available
information. The Adviser is also authorized to consider sales of shares of each
Fund and/or of any other investment companies for which the Adviser acts as
Adviser as a factor in the selection of brokers to execute brokerage and
principal transactions, subject to the requirements of "best execution," as
defined above.

         The research services discussed above may be in written form or through
direct contact with individuals and may include information as to particular
companies and securities as well as market, economic, or institutional areas and
information assisting the Trust in the valuation of the Funds' investments. The
research which the Adviser may receive for the Funds' brokerage commissions,
whether or not useful to a Fund, may be useful to the Adviser in managing the
accounts of the Adviser's other advisory clients. Similarly, the research
received for the commissions of such accounts may be useful to any Fund.

         In the over-the-counter market, securities are generally traded on a
"net" basis with dealers acting as principal for their own accounts without a
stated commission although the price of the security usually includes a profit
to the dealer. Money market instruments usually trade on a "net" basis as well.
On occasion, certain money market instruments may be purchased by the Funds
directly from an issuer in which case no commissions or discounts are paid. In
underwritten offerings, securities are purchased at a fixed price which includes
an amount of compensation to the underwriter, generally referred to as the
underwriter's concession or discount.


                                                                       Page B-24
<PAGE>   64


         For the fiscal years ended March 31, 1998 and 1999 brokerage
commissions (as opposed to dealer mark-ups) paid by the Funds were as follows:
TOTAL RETURN BOND FUND -- None; LOW DURATION BOND FUND -- None; ALPHATRAK 500
FUND -- [____]. The Adviser has not obtained any soft dollar benefits from
transactions by the Funds since inception of the Funds.


INVESTMENT ADVISORY SERVICES


         The Adviser, Metropolitan West Asset Management, LLC, with principal
offices at 11766 Wilshire Boulevard, Suite 1580, Los Angeles, California 90025,
is a registered investment adviser organized as a California limited liability
company in 1996.

                  Under the Investment Advisory Agreement relating to the Funds,
the Adviser provides the Funds with investment management services. As
compensation for these services, each Fund pays management fees at an annualized
rate of its average daily assets, as described in the Prospectus. For the fiscal
years ended March 31, 1998 and 1999 the amounts of the advisory fees earned by
the Adviser and the amounts of the reductions in fees and reimbursements of
expenses by the adviser as a result of the expense limitations and fee waivers
described in the Prospectus were as follows:

The Adviser has agreed to limit each Fund's expenses as described in the
Prospectus. Each Fund has agreed to reimburse the Adviser, for a period of up to
three years, for any such payments to the extent that the Fund's operating
expenses are otherwise below its expense cap. This obligation will not be
recorded on the books of the Fund to the extent that the total operating
expenses of the Fund are at or above the expense cap. However, if the total
operating expenses of a Fund fall below the expense cap, the reimbursement to
the Adviser will be accrued by the Fund as a liability. Certain officers and
trustees of the Funds are also officers and directors of the Adviser. All
officers serve without direct compensation from the Funds.


ADMINISTRATOR


         The Funds have an Administration Agreement with First Data Investor
Services Group, Inc. ("Investor Services Group" or the "Administrator"), with
offices at 3200 Horizon Drive, P.O. Box 61767, King of Prussia, Pennsylvania
19406. The Administration Agreement provides that the Administrator will prepare
and coordinate reports and other materials supplied to the Trustees; prepare
and/or supervise the preparation and filing of all securities filings, periodic
financial reports, prospectuses, statements of additional information, marketing
materials, tax returns, shareholder reports and other regulatory reports or
filings required of the Funds; prepare all required filings necessary to
maintain the Funds' qualifications and/or registrations to sell shares in all
states where each Fund currently does, or intends to do, business; coordinate
the preparation, printing and mailing of all materials (e.g., Annual Reports)
required to be sent to shareholders; coordinate the preparation and payment of
Fund-related expenses; monitor and oversee the activities of the Funds'
servicing agents (i.e., transfer agent, custodian, fund accountants, etc.);
review and adjust as necessary each Fund's daily expense accruals; and perform
such additional services as may be agreed upon by the Funds and the
Administrator. For its services, the Administrator receives an annual fee of
 .15% of the first $50 million of the Trust's average daily net assets, .10 % of
the next $50 million and .05% over $100 million, subject to a minimum annual fee
of $55,000 (and $12,000 for each additional series after the first). The
administrative fees paid by the TOTAL RETURN BOND FUND and the LOW DURATION BOND
FUND totaled $48,576 and $52,311, respectively, for the fiscal year ended March
31, 1998, and $51,360 and $158,288, respectively, for the fiscal year ended
March 31, 1999. The administrative fees paid by the ALPHATRAK 500 FUND totaled
$2,632 for the fiscal year ended March 31, 1999.


CUSTODIAN AND TRANSFER AGENT





                                                                       Page B-25
<PAGE>   65


         Investor Services Group also serves as the coordinator for custody
services provided by the custodian for the Funds under a Custody Administration
and Agency Agreement. The Bank of New York, 48 Wall Street, New York, New York
10286, serves as the Funds' custodian under a separate Custody Agreement. The
Administrator serves as the transfer agent for the Funds under a Transfer Agent
Services Agreement.


DISTRIBUTOR


         First Data Distributors, Inc. (the "Distributor"), 4400 Computer Drive,
Westboro, Massachusetts 01581, a broker-dealer affiliated with the
Administrator, acts as each Fund's principal underwriter in a continuous public
offering of the Fund's shares. After its initial term of two years, the
Underwriting Agreement between the Funds, the Adviser and the Distributor
continues in effect for periods not exceeding one year if approved at least
annually by (i) the Board of Trustees or the vote of a majority of the
outstanding shares of each Fund (as defined in the 1940 Act) and (ii) a majority
of the Trustees who are not parties to such agreement or interested persons of
any such party, in each case cast in person at a meeting called for the purpose
of voting on such approval. The Distribution Agreement may be terminated without
penalty by the parties thereto upon 60 days' written notice, and is
automatically terminated in the event of its assignment as defined in the 1940
Act.


SHARE MARKETING PLAN


         The Trust has adopted has adopted a Share Marketing Plan (or Rule 12b-1
Plan) (the "12-b-1 Plan") with respect to the Funds pursuant to Rule 12b-1 under
the 1940 Act. The Adviser serves as the distribution coordinator under the 12b-1
Plan and, as such, receives for disbursement any fees paid by the Funds pursuant
to the 12b-1 Plan.


         On April 1, 1997, the Board of Trustees of the Trust, including a
majority of the Trustees who are not interested persons of the Trust and who
have no direct or indirect financial interest in the operation of the 12b-1 Plan
or in any agreement related to the 12b-1 Plan (the "Independent Trustees")
adopted the 12b-1 Plan.

         Under the 12b-1 Plan, each Funds pays distribution fees to the Adviser
at an annual rate of up to 0.25% of the Fund's aggregate average daily net
assets to reimburse the Adviser for its expenses in connection with the
promotion and distribution of the shares. The Funds and the Adviser presently
are waiving all Rule 12b-1 fees. The Funds would notify shareholders in writing
at least 30 days before rescinding that waiver.


         The 12b-1 Plan provides that the Adviser may use the Rule 12b-1
distribution fees received from a Fund only to pay for the distribution and
shareholder servicing expenses of that Fund. Distribution fees are accrued daily
and paid monthly, and are charged as expenses of the shares as accrued.


         A Fund's shares are not obligated under the 12b-1 Plan to pay any
distribution expense in excess of the distribution fee. Thus, if the 12b-1 Plan
were terminated or otherwise not continued, no amounts (other than current
amounts accrued but not yet paid) would be owed to the Adviser.

         The 12b-1 Plan provides that it shall continue in effect from year to
year provided that a majority of the Board of Trustees of the Trust, including a
majority of the Independent Trustees, vote annually to continue the 12b-1 Plan.
The 12b-1 Plan (and any distribution agreement between the Trust, the
Distributor or the Adviser and a selling agent) may be terminated without
penalty upon at least 60-days' notice by the Distributor or the Adviser, or by
the Trust by vote of a majority of the Independent Trustees, or by vote of a
majority of the outstanding shares (as defined in the 1940 Act).

         All distribution fees paid by the Funds under the 12b-1 Plan will be
paid in accordance with Conduct Rule 2830 of NASD Regulation, Inc., as such Rule
may change from time to time. Pursuant to the 12b-1 Plan, the Board of Trustees
will review at least quarterly a written report of the distribution expenses
incurred by the Adviser on behalf of each Fund. In addition, as long as the
12b-1 Plan remains in effect, the selection and nomination of Trustees who are
not interested persons (as defined in the Investment Company Act) of the Trust
shall be made by the Trustees then in office who are not interested persons of
the Trust.

                                 NET ASSET VALUE


         As stated in the Prospectus, the net asset value per share of each
Fund's shares will be determined at the close of the New York Stock Exchange
(the "NYSE") (generally 4:00 p.m. New York time, but the NYSE sometimes closes
earlier) on each day that the NYSE is open for trading and banks are open for
business. The NYSE annually announces the days on which it will not be open for
trading; the most recent announcement indicates that it will not be open on the
following days: New Year's Day, Martin Luther




                                                                       Page B-26
<PAGE>   66



King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day and Christmas Day. Banks are also closed on Columbus
Day and Veterans' Day. However, the NYSE and banks may close on days not
included in that announcement. Also, no Fund is required to compute its net
asset value on any day on which no order to purchase or redeem its shares is
received. The daily net asset value may not reflect the closing market price for
all futures contracts held by the Funds because the markets for certain futures
close shortly after the time net asset value is calculated.


         Fixed-income securities which are traded on a national securities
exchange will be valued at the last sale price or, if there was no sale on such
day, at the average of readily available closing bid and asked prices on such
exchange. However, securities with a demand feature exercisable within one to
seven days are valued at par. The Funds receive pricing information from
Interactive Data Corporation ("IDC") and other independent pricing vendors. IDC
and others, including Merrill Lynch, Bloomberg and Muller, are regarded as some
of the more common sources of readily available pricing information for
fixed-income securities. Prices provided by IDC and other private vendors also
may be based on quotations from one or more market makers.


         The Funds use a benchmark pricing system to the extent prices for
securities are either inaccurate (such as when the reported prices are different
from recent known market transactions) or are not available from IDC or another
pricing source. For a security priced using this system, the Adviser initially
selects a benchmark composed of a relevant U.S. Treasury security and a
multiplier, divisor or margin that the Adviser believes would together best
reflect changes in the market value of the security. The Adviser adjusts the
value of the security daily based on changes to the market price of the assigned
benchmark. Once each month the Adviser obtains from one or more dealers an
independent review of prices produced by the benchmark system as well as a
review of the benchmark selected to adjust the price. Although the Adviser
believes that benchmark pricing is the most reliable method for pricing
securities not priced by IDC or others, there is no assurance that the benchmark
price reflects the actual price for which a Fund could sell a security. The
accuracy of benchmark pricing depends on the judgment of one or more market
makers regarding a security's market price, as well as the choice of the
appropriate benchmark, subject to review by the Adviser. The benchmark pricing
system is continuously reviewed by the Adviser and implemented according to the
pricing policy reviewed by the Board of Trustees.


         Debt securities which mature in less than 60 days are valued at
amortized cost (unless the Board of Trustees determines that this method does
not represent fair value), if their original maturity was 60 days or less or by
amortizing the value as of the 61st day prior to maturity, if their original
term to maturity exceeded 60 days.

         Trading in securities listed on foreign securities exchanges or
over-the-counter markets is normally completed before the close of regular
trading on the NYSE. In addition, foreign securities trading may not take place
on all business days in New York and may occur on days on which the NYSE is not
open. In addition, foreign currency exchange rates are generally determined
prior to the close of trading on the NYSE. Events affecting the value of foreign
securities and currencies will not be reflected in the determination of net
asset value unless the Board of Trustees determines that the particular event
would materially affect net asset value, in which case an adjustment will be
made. Investments quoted in foreign currency are valued daily in U.S. dollars on
the basis of the foreign currency exchange rate prevailing at the time of
valuation. Foreign currency exchange transactions conducted on a spot basis are
valued at the spot rate prevailing in the foreign exchange market.

         Securities and other assets that cannot be valued as described above
will be valued at their fair value as determined by the Adviser under guidelines
established by and under the general supervision and responsibility of the Board
of Trustees.

                               REDEMPTION IN KIND


         If the Board of Trustees determines that it would be detrimental to the
best interests of the remaining shareholders of any Fund to make payment wholly
in cash, the Fund may pay the redemption price in part by a distribution in kind
of readily marketable securities from the portfolio of that Fund, in lieu of
cash. The Trust has elected to be governed by Rule 18f-1 under the 1940 Act
pursuant to which each Fund is obligated to redeem shares solely in cash up to
the lesser of $250,000 or one percent of the net asset value of the Fund during
any 90-day period for any one shareholder. Should redemptions by any shareholder
exceed such limitation the Fund will have the option of redeeming the excess in
cash or in kind. If shares are redeemed in kind, the redeeming shareholder would
incur brokerage costs in converting the assets into cash.


                            DIVIDENDS AND TAX STATUS


         Each Fund has elected and intends to continue to qualify to be treated
as a regulated investment company under Subchapter M of the Code. Each Fund is
taxed as a separate entity under Subchapter M and must qualify on a separate
basis. Qualification as a regulated investment company requires, among other
things, that (a) at least 90% of a Fund's annual gross income, without offset
for losses from the sale or other disposition of securities, be derived from
interest, dividends, payments with respect to securities





                                                                       Page B-27
<PAGE>   67


loans, and gains from the sale or other disposition of securities, foreign
currencies or options (including forward contracts) thereon; and (b) a Fund
diversify its holdings so that, at the end of each quarter of the taxable year,
(i) at least 50% of the market value of the Fund's assets is represented by
cash, U.S. Government securities, securities of other regulated investment
companies and other securities limited in respect of any one issuer to an amount
not greater than 5% of the Fund's 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 of any one issuer (other than U.S. Government
securities). In addition, in order to qualify as a regulated investment company
a Fund must distribute to its shareholders at least 90% of its net investment
income, other than net capital gains, earned in each year. As such, and by
complying with the applicable provisions of the Code, a Fund will not be subject
to federal income tax on taxable income (including realized capital gains) that
it distributes to shareholders in accordance with the timing requirements of the
Code.

         A Fund must pay an excise tax to the extent it does not distribute to
its shareholders during each calendar year at least 98% of its ordinary income
for that calendar year, 98% of its capital gains over capital losses for the
one-year period ending October 31 in such calendar year, and all undistributed
ordinary income and capital gains for the preceding respective one-year period.
The Funds intend to meet these distribution requirements to avoid excise tax
liability. If the net asset value of shares of a Fund should, by reason of a
distribution of realized capital gains, be reduced below a shareholder's cost,
such distribution would to that extent be a return of capital to that
shareholder even though taxable to the shareholder, and a sale of shares by a
shareholder at net asset value at that time would establish a capital loss for
Federal income tax purposes.


         The Taxpayer Relief Act (the "Relief Act") reduced the maximum tax on
long-term capital gains from 28% to 20% for taxpayers in all brackets except for
those in the 15% bracket, whose maximum rate will be 10% on those gains. Certain
provisions of the Relief Act have since been changed and further changes not
described in this Statement of Additional Information are possible.


         Corporate shareholders are eligible to deduct 70% of dividends received
from domestic corporations. The Funds pass through this benefit to their
corporate shareholders subject to limitations under Section 854 of the Code. The
dividends-received deduction is allowed to a corporate shareholder only if the
shareholder satisfies a 46-day holding period for the dividend-paying stock (or
a 91-day period for certain dividends on preferred stock). The 46-day (91-day)
holding period generally does not include any time in which the shareholder is
protected from the risk of loss otherwise inherent in the ownership of an equity
interest. The Relief Act provided that the taxpayer must satisfy the holding
period requirement with respect to each dividend. This determination is made by
looking at the 90-day (180-day) period starting 45 days (90 days) before the
ex-date. The 46 days (91 days) do not have to be consecutive and do not include
any day in which risk of loss is diminished.

         A Fund must satisfy the above holding period requirements in order to
pass through this benefit to its corporate shareholders. In addition, a
corporate shareholder of a Fund must also satisfy the holding period requirement
with respect to its Fund Shares. In determining the extent to which a Fund's
dividends may be eligible for the 70% dividends-received deduction by corporate
shareholders, interest income, capital gain net income, gain or loss from
Section 1256 contracts (described below), dividend income from foreign
corporations and income from other sources will not constitute qualified
dividends. Corporate shareholders should consult their tax advisers regarding
other requirements applicable to the dividends-received deduction.

         The use of hedging strategies, such as entering into futures contracts
and forward contracts and purchasing options, involves complex rules that will
determine the character and timing of recognition of the income received in
connection therewith by the Funds. Income from foreign currencies (except
certain gains therefrom that may be excluded by future regulations) and income
from transactions in options, futures contracts and forward contracts derived by
a Fund with respect to its business of investing in securities or foreign
currencies will qualify as permissible income under Subchapter M of the Code.

         For accounting purposes, when a Fund purchases an option, the premium
paid by the Fund is recorded as an asset and is subsequently adjusted to the
current market value of the option. Any gain or loss realized by a Fund upon the
expiration or sale of such options held by the Fund generally will be capital
gain or loss.

         Any security, option, or other position entered into or held by a Fund
that substantially diminishes the Fund's risk of loss from any other position
held by the Fund may constitute a "straddle" for federal income tax purposes. In
general, straddles are subject to certain rules that may affect the amount,
character and timing of a Fund's gains and losses with respect to straddle
positions by requiring, among other things, that the loss realized on
disposition of one position of a straddle be deferred until gain is realized on
disposition of the offsetting position; that the Fund's holding period in
certain straddle positions not begin until the straddle is terminated (possibly
resulting in the gain not being treated as long-term capital gain); and that
losses recognized with respect to certain straddle positions, which would
otherwise constitute short-term capital losses, be treated as long-term losses.
Different elections are available to a Fund that may mitigate the effects of the
straddle rules.



                                                                       Page B-28
<PAGE>   68

         Certain options, futures contracts and forward contracts that are
subject to Section 1256 of the Code ("Section 1256 Contracts") and that are held
by a Fund at the end of its taxable year generally will be required to be
"marked to market" for federal income tax purposes, that is, deemed to have been
sold at market value. Sixty percent of any net gain or loss recognized on these
deemed sales and 60% of any net gain or loss realized from any actual sales of
Section 1256 Contracts will be treated as long-term capital gain or loss, and
the balance will be treated as short-term gain or loss.

         A Fund may be subject to foreign withholding taxes on dividends and
interest earned with respect to securities of foreign corporations. A Fund may
invest in the stock of foreign investment companies that may be treated as
"passive foreign investment companies" ("PFICs") under the Code. Certain other
foreign corporations, not operated as investment companies, may nevertheless
satisfy the PFIC definition. A portion of the income and gains that a Fund
derives from PFIC stock may be subject to a non-deductible federal income tax at
the Fund level. In some cases, a Fund may be able to avoid this tax by electing
to be taxed currently on its share of the PFIC's income, whether or not such
income is actually distributed by the PFIC. Each Fund will endeavor to limit its
exposure to the PFIC tax by investing in PFICs only where the election to be
taxed currently will be made. Because it is not always possible to identify a
foreign issuer as a PFIC in advance of making the investment, a Fund may incur
the PFIC tax in some instances.

         Under Section 988 of the Code, gains or losses attributable to
fluctuations in exchange rates which occur between the time a Fund accrues
interest or other receivables or accrues expenses or other liabilities
denominated in a foreign currency and the time the Fund actually collects such
receivables or pays such liabilities are treated as ordinary income or loss.
Similarly, gains or losses on forward foreign currency exchange contracts (other
than forward foreign currency exchange contracts that are governed by Section
1256 of the Code and for which no election is made) or dispositions of debt
securities denominated in a foreign currency attributable to fluctuations in the
value of the foreign currency between the date of acquisition of the security
and the date of disposition are also treated as ordinary gain or loss. These
gains and losses, referred to as "Section 988" gains or losses, increase or
decrease the amount of a Fund's investment company taxable income available to
be distributed to its shareholders as ordinary income, rather than increasing or
decreasing the Fund's net capital gain. If a Fund's Section 988 losses exceed
other investment company taxable income during a taxable year, the Fund would
not be able to make any ordinary dividend distributions, or distributions made
before the losses were realized would be recharacterized as a return of capital
to shareholders, rather than as an ordinary dividend, reducing the basis of each
shareholder's shares.

         Any loss realized on a sale, redemption or exchange of shares of a Fund
by a shareholder will be disallowed to the extent the shares are replaced within
a 61-day period (beginning 30 days before the disposition of shares). Shares
received in connection with the payment of a dividend by a Fund constitute a
replacement of shares.

         The above discussion and the related discussion in the Prospectus are
not intended to be complete discussions of all applicable federal tax
consequences of an investment in a Fund. Paul, Hastings Janofsky & Walker LLP
has expressed no opinion in respect thereof. Nonresident aliens and other
foreign persons are subject to different tax rules, and may be subject to United
States federal income tax withholding of up to 30% on certain payments received
from a Fund. Shareholders are advised to consult with their own tax advisers
concerning the application of federal, state, local, and foreign taxes to an
investment in a Fund.

                             PERFORMANCE INFORMATION

         TOTAL RETURN: Average annual total return quotations used in the Funds'
advertising and promotional materials are calculated according to the following
formula:

         P(1 + T) to the nth power = ERV

         where P equals a hypothetical initial payment of $1000; T equals
average annual total return; n equals the number of years; and ERV equals the
ending redeemable value at the end of the period of a hypothetical $1000 payment
made at the beginning of the period.

         Under the foregoing formula, the time periods used in advertising will
be based on rolling calendar quarters, updated to the last day of the most
recent quarter prior to submission of the advertising for publication. Average
annual total return, or "T" in the above formula, is computed by finding the
average annual compounded rates of return over the period that would equate the
initial amount invested to the ending redeemable value. Average annual total
return assumes the reinvestment of all dividends and distributions.



                                                                       Page B-29

</TABLE>

         *Total return for periods of less than one year are aggregate, not
         annualized. The inception dates were: TOTAL RETURN BOND FUND, March 31,
         1997; LOW DURATION BOND FUND, March 31, 1997; and ALPHATRAK 500 FUND,
         June 29, 1998.


                   YIELD: Annualized yield quotations used in a Fund's
advertising and promotional materials are calculated by dividing the Fund's
income for a specified 30-day period, net of expenses, by the average number of
shares outstanding during the period, and expressing the result as an annualized
percentage (assuming semi-annual compounding) of the net asset value per share
at the end of the period. Yield quotations are calculated according to the
following formula:

                   YIELD = 2 [ (a-b + 1) to the 6th power - 1]
                                ---
                                cd

         where a equals dividends and interest earned during the period; b
equals expenses accrued for the period, net of reimbursements; c equals the
average daily number of shares outstanding during the period that are entitled
to receive dividends; and d equals the maximum offering price per share on the
last day of the period.

         Except as noted below, in determining net investment income earned
during the period ("a" in the above formula), a Fund calculates interest earned
on each debt obligation held by it during the period by (1) computing the
obligation's yield to maturity, based on the market value of the obligation
(including actual accrued interest) on the last business day of the period or,
if the obligation was purchased during the period, the purchase price plus
accrued interest; (2) dividing the yield to maturity by 360; and (3) multiplying
the resulting quotient by the market value of the obligation (including actual
accrued interest). Once interest earned is calculated in this fashion for each
debt obligation held by the Fund, net investment income is then determined by
totaling all such interest earned.


         Yield for the TOTAL RETURN BOND FUND for the 30-day period ended March
31, 1999 was 6.97% and for the LOW DURATION BOND FUND was 7.06%.


         For purposes of these calculations, the maturity of an obligation with
one or more call provisions is assumed to be the next date on which the
obligation reasonably can be expected to be called or, if none, the maturity
date.


         OTHER INFORMATION: Each Fund's performance data quoted in advertising
and other promotional materials represents past performance and is not intended
to predict or indicate future results. The return and principal value of an
investment in a Fund will fluctuate, and an investor's redemption proceeds may
be more or less than the original investment amount. In advertising and
promotional materials a Fund may compare its performance with data published by
Lipper Analytical Services, Inc. ("Lipper") or CDA Investment Technologies, Inc.
("CDA"). The Fund also may refer in such materials to mutual fund performance
rankings and other data, such as comparative asset, expense and fee levels,
published by Lipper or CDA. Advertising and promotional materials also may refer
to discussions of the Fund and comparative mutual fund data and ratings reported
in independent periodicals including, but not limited to, The Wall Street
Journal, Money magazine, Forbes, Business Week, Financial World and Barron's.
The Funds also may quote or refer to other portfolio or performance statistics
that are intended to reflect historical volatility and other performance
information, including the following: (1) Beta (the covariance of a share in
relation to the rest of the market, with volatility equal to the market having a
beta of 1); (2) R-squared (R2 reflects the degree to which the Fund's movements
are explained by movements in its benchmark index. R2 can range from 0 to 1 with
1 meaning that all movements of a fund are explained by movements of the index);
(3) Alpha (alpha measures the Fund's return relative to an unmanaged portfolio
index and is a general measure of the relative value a portfolio manager has
contributed. A value greater than 0 indicates a positive contribution); and (4)
Correlation coefficient (correlation coefficient provides a measure of how
closely the returns of one variable [the fund] moves with another [the index].

ranges from -1 to +1, with +1, indicating a perfect positive correlation,
occurring only when the returns of the two variables move exactly at the same
time, in the same direction, and in the same relative magnitude).

                       FURTHER INFORMATION ABOUT THE TRUST

         The Declaration of Trust for the Trust permits the Trustees to issue an
unlimited number of full and fractional shares of beneficial interest and to
divide or combine the shares into a greater or lesser number of shares without
thereby changing the proportionate beneficial interest in each Fund. Each share
represents an interest in a Fund proportionately equal to the interest of each
other share. Upon the Trust's liquidation, all shareholders would share pro rata
in the net assets of the Fund in question available for distribution to
shareholders. If they deem it advisable and in the best interest of
shareholders, the Board of Trustees may create additional classes of shares
which differ from each other only as to dividends. Each of such classes has or
will have a designation including the word "Series." Income and operating
expenses not specifically attributable to a particular Fund are allocated fairly
among the Funds by the Trustees, generally on the basis of the relative net
assets of each Fund.


         The Declaration of Trust provides that the Trustees will not be liable
for errors of judgment or mistakes of fact or law, but nothing in the
Declaration of Trust protects a Trustee against any liability to which he would
otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his
office. The Declaration of Trust also provides that the Trust shall, upon
request, assume the defense of any claim made against any shareholder for any
act or obligation of the Trust and satisfy any judgment thereon.

         The Trust's custodian is responsible for holding the Funds' assets and
acts as the Trust's accounting services agent. Subcustodians provide custodial
services for assets of the Trust held outside the U.S. The Trust's independent
accountants examine the Trust's financial statements and assist in the
preparation of certain reports to the Securities and Exchange Commission.

                       APPENDIX -- DESCRIPTION OF RATINGS
- --------------------------------------------------------------------------------


MOODY'S INVESTORS SERVICE

BOND RATINGS:

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

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

Moody's applies numerical modifiers "l", "2" and "3" in each generic rating
classification from Aa through B. The modifier "l" indicates that the obligation
ranks in the higher end of its generic rating category; the modifier "2"
indicates a mid-range ranking; and the modifier "3" indicates that the company
ranks in the lower end of that generic rating category.

"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 over the future. Uncertainty of position
characterizes bonds in this class.

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

SHORT-TERM DEBT RATINGS:

Moody's short-term debt ratings are opinions regarding the ability of issuers to
repay punctually senior debt obligations. These obligations have an original
maturity not exceeding one year, unless explicitly noted.

"P-1"--Issuers rated "Prime-l" or "P-1" (or supporting institutions) have a
superior ability for repayment of senior short-term debt obligations.

"P-2"--Issuers rated "Prime-2" or "P-2" (or supporting institutions) have a
strong ability for repayment of senior short-term debt obligations.

STANDARD & POOR'S RATING GROUP

BOND RATINGS:

"AAA"--Debt rated AAA has the highest rating assigned by
S&P. Capacity to pay interest and repay principal is extremely
strong.

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

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

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

Debt rated BB and B is regarded as having predominantly speculative
characteristics with respect to capacity to pay interest and repay principal.
While such debt will likely have some quality and protective characteristics,
these are outweighed by large uncertainties or major exposures to adverse
conditions.

COMMERCIAL PAPER RATINGS:

An S&P commercial paper rating is a current assessment of the likelihood of
timely payment of debt considered short-term in the relevant market.




                                                                       Page B-33
<PAGE>   73



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

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

FITCH INVESTORS SERVICES, INC.

BOND RATINGS:

The following summarizes the ratings used by Fitch for corporate bonds:

"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 issuers 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.

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

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

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

Plus (+) Minus (-)--Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "AAA" category.

SHORT-TERM DEBT RATINGS:

"F-1+"--Exceptionally Strong Credit Quality. Issues assigned
this rating are regarded as having the strongest degree of

assurance for timely payment.

"F-1"--Very Strong Credit Quality. Issues assigned this rating
reflect an assurance of timely payment only slightly less in
degree than issues rated "F-1+."

"F-2"--Good Credit Quality. Issues assigned this rating have a satisfactory
degree of assurance for timely payment, but the margin of safety is not as great

as for issues assigned "F-1+" or "F-1" ratings.

DUFF & PHELPS CREDIT RATING CO.

BOND RATINGS:

The following summarizes the ratings used by Duff & Phelps for long-term debt:

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

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

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

"BBB+," "BBB," "BBB-"--Below average protection factors but still considered
sufficient for prudent investment. Considerable variability in risk during
economic cycles.

"BB+," "BB," "BB-"--Below investment grade but deemed likely to meet obligations
when due. Present or prospective financial protection factors fluctuate
according to industry conditions or company fortunes. Overall quality may move
up or down frequently within this category.

"B+," "B," "B-"--Below investment grade and possessing risk that obligations
will not be met when due. Financial protection factors will fluctuate widely
according to economic cycles, industry conditions and/or company fortunes.
Potential exists for frequent changes in the rating within this category or into
a higher or lower rating grade.




                                                                       Page B-34
<PAGE>   74


SHORT-TERM DEBT RATINGS:

"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.



                                                                       Page B-35

Item 25. Indemnification

       Article VII of the Agreement and Declaration of Trust empowers the
Trustees of the Trust, to the full extent permitted by law, to purchase with
Trust assets insurance for indemnification from liability and to pay for all
expenses reasonably incurred or paid or expected to be paid by a Trustee or
officer in connection with any claim, action, suit or proceeding in which he or
she becomes involved by virtue of his or her capacity or former capacity with
the Trust.

       Article VII of the By-Laws of the Trust provides that the Trust shall
indemnify any person who was or is a party or is threatened to be made a party
to any proceeding by reason of the fact that such person is and other amounts or
was an agent of the Trust, against expenses, judgments, fines, settlement and
other amounts actually and reasonable incurred in connection with such
proceeding if that person acted in good faith and reasonably believed his or her
conduct to be in the best interests of the Trust. Indemnification will not be
provided in certain circumstances, however, including instances of willful
misfeasance, bad faith, gross negligence, and reckless disregard of the duties
involved in the conduct of the particular office involved.

       Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to the Trustees, officers and controlling persons
of the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable in the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a Trustee, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such Trustee, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.
