                                FUND HIGHLIGHTS
 
                  WHAT ARE THE KEY FACTS REGARDING THE FUNDS?
 
Q: What are the Funds' goals?
 
A:
     
  . The Framlington Emerging Markets Fund, Framlington Global Financial
    Services Fund, Framlington Healthcare Fund, Framlington International
    Growth Fund, Growth Opportunities Fund, International Equity Fund, Micro-
    Cap Equity Fund, Multi-Season Growth Fund, NetNet Fund, Small-Cap Value
    Fund, Small Company Growth Fund and Value Fund primarily seek to provide
    long-term capital appreciation.     
 
  . The Balanced Fund, Growth & Income Fund and Real Estate Equity Investment
    Fund seek to provide capital appreciation and current income.
 
Q: What are the Funds' strategies?
 
A: The Funds, other than the Balanced Fund, invest primarily in Equity
Securities. The Balanced Fund allocates its assets primarily among three types
of assets--Equity Securities, Fixed Income Securities and Cash Equivalents.
"Equity Securities" include common stocks, preferred stocks, warrants and
other securities convertible into common stock. "Fixed Income Securities" are
securities which either pay interest at set times at either fixed or variable
rates, or which realize a discount upon maturity. Fixed Income Securities
include corporate bonds, debentures, notes and other similar corporate debt
instruments, zero coupon bonds (discount debt obligations that do not make
interest payments) and variable amount master demand notes that permit the
amount of indebtedness to vary in addition to providing for periodic
adjustments in the interest rates. "Cash Equivalents" are instruments which
are highly liquid and virtually free of investment risk.
 
Q: What are the Funds' risks?
 
A: The following table summarizes the primary risks of investing in the Funds:

  All Funds                             Potential loss of investment due to
                                        changes in the stock market in
                                        general, changes in the stock prices
                                        of particular companies and
                                        perceptions about particular
                                        industries.
- ------------------------------------------------------------------------------
  International Equity Fund,            Because of large investments in
  Framlington                           foreign securities, the Funds are
  Emerging Markets Fund, Framlington    riskier than domestic funds due to
  Global Financial Services Fund and    factors such as freezes on
  Framlington                           convertibility of currency, changes in
  International Growth Fund             exchange rates, political instability
                                        and differences in accounting and
                                        reporting standards.
- ------------------------------------------------------------------------------
  Growth Opportunities Fund,            Because of large investments in mid-
  Micro-Cap Equity Fund,                capitalization, small-capitalization
  NetNet Fund,                          and/or emerging growth companies, the
  Small-Cap Value Fund and              Funds are riskier than large-
  Small Company Growth Fund             capitalization funds since such
                                        companies typically have greater
                                        earnings fluctuations and greater
                                        reliance on a few key customers than
                                        larger companies.

                            FUND OPERATING EXPENSES
   
  The purpose of this table is to assist you in understanding the expenses
charged directly to each Fund, which investors in the Funds will bear
indirectly for the current fiscal year. Such expenses include payments to
Trustees, Directors, auditors, legal counsel and service providers (such as
the Advisor), registration fees and distribution fees. The expenses shown
below are based on expenses for the Funds' past fiscal year, except (i) the
expenses for the Growth Opportunities Fund and the Framlington Global
Financial Services Fund are based on estimated operating expenses for the
current fiscal year, (ii) the expenses for the NetNet Fund have been restated
to reflect the discontinuation of the voluntary 12b-1 fee waiver for Class A
Shares and (iii) the expenses for the Framlington Emerging Markets Fund and
Framlington International Growth Fund have been restated to reflect
anticipated voluntary expense reimbursements for the current fiscal year. The
Advisor and/or Distributor may discontinue such voluntary waivers or expense
reimbursements at any time in their sole discretion. Because of the 12b-1 fee,
you may over the long term pay more than the amount of the maximum permitted
front-end sales charge.

                            WHAT FUNDS ARE OFFERED?
   
  This Prospectus offers Class A, Class B and Class C Shares of the Funds
described below. This section summarizes each Fund's principal investments.
The sections entitled "What are the Funds' Investments and Investment
Practices?" and "What are the Risks of Investing in the Funds?" and the SAI
give more information about the Funds' investment techniques and risks.
Capitalized terms are explained in the section entitled "What are the Funds'
Investments and Investment Practices?"     
 
                                 BALANCED FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide an attractive
investment return through a combination of growth of capital and current
income. The Fund will allocate its assets among three asset groups: Equity
Securities, Fixed Income Securities and Cash Equivalents.
 
  .The Fund normally will invest at least 25% of its assets in Fixed Income
   Securities and no more than 75% of its assets in Equity Securities. The
   Fund will notify shareholders at least 30 days before changing this
   policy.
 
  The Advisor will allocate the Fund's assets to the three asset groups based
on its view of the following factors, among others:
 
  .general market and economic conditions and trends
 
  .interest rates and inflation rates
 
  .fiscal and monetary developments
 
  .long-term corporate earnings growth.
 
  The Advisor will try to take advantage of changing economic conditions by
adjusting the ratio of Equity Securities to Fixed Income Securities or Cash
Equivalents. For example, if the Advisor believes that rapid economic growth
will lead to better corporate earnings in the future, then it might increase
the Fund's Equity Securities holdings and reduce its Fixed Income Securities
and Cash Equivalents holdings.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                             GROWTH & INCOME FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide capital
appreciation and current income. It primarily invests in dividend-paying
Equity Securities and is designed for investors seeking current income and
capital appreciation from the equity markets.
 
  .Under normal circumstances, the Fund will invest at least 65% of its
   assets in income-producing common stocks and convertible preferred stocks.
 
  .The Fund may also purchase Fixed Income Securities which are convertible
   into or exchangeable for common stock.
 
  .The Fund may invest up to 35% of its assets in Fixed Income Securities,
   including 20% of its assets in Fixed Income Securities that are rated
   below investment grade.
 
  The Advisor generally selects large, well-known companies that it believes
have favorable prospects for dividend growth and capital appreciation. The
Fund will seek to produce a current yield greater than the Standard & Poor's
500 Composite Stock Price Index ("S&P 500").
 
  The Fund focuses on dividend-paying Equity Securities because, over time,
dividend income has accounted for a significant portion of the total return of
the S&P 500. In addition, dividends are usually a more stable and predictable
source of return than capital appreciation. The Advisor believes that stocks
which distribute a high level of current income generally have more stable
prices than those which pay below average dividends.

  PORTFOLIO MANAGEMENT. Otto Hinzmann, Jr. is the Fund's portfolio manager, a
position he has held since February 1995. Mr. Hinzmann has been a Vice
President and Director of Equity Management of the Advisor or Old MCM, Inc.
("MCM"), the predecessor to the Advisor, since January 1987.
 
                           GROWTH OPPORTUNITIES FUND
   
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. The Fund invests at least 65% of its assets in the
Equity Securities of companies with market capitalizations between $500
million and $10 billion. Its style, which focuses on both growth prospects and
valuation, is known as GARP (Growth at a Reasonable Price) and seeks to
produce attractive returns during various market environments.     
 
  The Advisor chooses the Fund's investments as follows: The Advisor reviews
the earnings growth of approximately 10,000 companies over the past three
years. It invests in approximately 50 to 100 companies based on:
 
  .superior earnings growth
 
  .financial stability
 
  .relative market value
 
  .price changes compared to the Standard & Poor's MidCap 400 Index.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                           INTERNATIONAL EQUITY FUND
   
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. The Fund invests primarily in Foreign Securities and
American Depositary Receipts ("ADRs"). At least once a quarter, the Advisor
creates a list of Foreign Securities and ADRs (the "Securities List") which
the Fund may purchase based on the country where the company is located, its
competitive advantages, its past financial record, its future prospects for
growth and the market for its securities. The Advisor updates the Securities
List frequently (at least quarterly), adds new securities to the Securities
List if they are eligible and sells securities not on the updated Securities
List as soon as practicable.     
   
  After the Advisor creates the Securities List, it divides the list into two
sections. The first section is designed to provide broad coverage of
international markets. The second section increases exposure to securities
that the Advisor expects will perform better than other stocks in their
industry sectors and their markets as a whole. When the Advisor believes
broader market exposure will benefit the Fund, it will allocate up to 100% of
the Fund's assets in first section securities. When the Advisor identifies
strong potential for specific securities to perform well, the Fund may invest
up to 50% of its assets in second section securities.     
 
  .Under normal market conditions, at least 65% of the Fund's assets are
   invested in Equity Securities in at least three foreign countries.
     
  .The Fund emphasizes companies with a market capitalization of at least
   $250 million.     
 
  PORTFOLIO MANAGEMENT. Todd B. Johnson and Theodore Miller jointly manage the
Fund. Mr. Johnson, a Chief Investment Officer of the Advisor, and Mr. Miller,
senior portfolio manager of the Fund, have managed the Fund since July 1992
and October 1996, respectively. Mr. Miller previously worked as the primary
analyst for the Fund (1996) and for Interacciones Global Inc. (1993-1995) and
McDonald & Co. Securities Inc. (1991-1993).

                             MICRO-CAP EQUITY FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. It invests primarily in Equity Securities of smaller
capitalization companies. The Fund attempts to provide investors with
potentially higher returns than a fund that invests primarily in larger more
established companies. Since smaller capitalization companies are generally
not as well known to investors and have less of an investor following than
larger companies, they may provide higher returns due to inefficiencies in the
marketplace.
 
  .Under normal market conditions, the Fund will invest at least 65% of its
   assets in Equity Securities of companies having a market capitalization of
   $200 million or less, which is considerably less than the market
   capitalization of S&P 500 companies.
 
  The Advisor will choose companies that:
 
  .present the ability to grow significantly over the next several years
 
  .may benefit from changes in technology, regulations and industry sector
   trends
 
  .are still in the developmental stage and may have limited product lines.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                           MULTI-SEASON GROWTH FUND
   
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. This goal is "fundamental" and cannot be changed without
shareholder approval. Its style, which focuses on both growth prospects and
valuation, is known as GARP (Growth at a Reasonable Price) and seeks to
produce attractive returns during various market environments. The Fund
invests at least 65% of its assets in Equity Securities. The Fund generally
invests in Equity Securities of companies with market capitalizations over $1
billion.     
 
  The Advisor chooses the Fund's investments as follows: The Advisor reviews
the earnings growth of approximately 5,500 companies over the past five years.
It invests in approximately 50 to 100 companies based on:
 
  .superior earnings growth
 
  .financial stability
 
  .relative market value
 
  .price changes compared to the S&P 500.
   
  PORTFOLIO MANAGEMENT. Leonard J. Barr II is the Fund's portfolio manager, a

  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. Under normal conditions, the Fund will invest at least
65% of its assets in Equity Securities.
 
  In choosing which companies' stock the Fund should purchase, the Advisor
invests in those companies listed on a U.S. securities exchange or NASDAQ
which are engaged in the research, design, development or manufacturing, or
engaged to a significant extent in the business of distributing products,
processes or services for use with Internet or Intranet related businesses.
The Internet is a world-wide network of computers designed to permit users to
share information and transfer data quickly and easily. The World Wide Web
("WWW"), which is a means of graphically interfacing with the Internet, is a
hyper-text based publishing medium containing

  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                      REAL ESTATE EQUITY INVESTMENT FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide both capital
appreciation and current income. This goal is "fundamental" and cannot be
changed without shareholder approval. The Fund invests primarily in U.S.
companies which are principally engaged in the real estate industry or which
own significant real estate. A company is "principally engaged" in the real
estate industry if at least 50% of its assets, gross income or net profits are
attributable to ownership, construction, management or sale of residential,
commercial or industrial real estate. The Fund will not own real estate
directly.

in Equity Securities of U.S. companies in the real estate industry including:

   companies
 
  .in Fixed Income Securities including up to 5% of its assets in debt
   securities rated below investment grade or unrated if secured by real
   estate assets if the Advisor believes that the underlying collateral is
   sufficient
 
  .in REITS only if they are traded on a securities exchange or NASDAQ.
   
  PORTFOLIO MANAGEMENT. Peter K. Hoglund and Robert E. Crosby jointly manage
the Fund. Mr. Hoglund has managed the Fund since October 1996. Mr. Hoglund

                             SMALL-CAP VALUE FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation, with income as a secondary objective. It invests
primarily in Equity Securities of smaller capitalization companies. The Fund
attempts to provide investors with potentially higher returns than a fund that
invests primarily in larger more established companies. Since small companies
are generally not as well known to investors and have less of an investor
following than larger companies, they may provide higher returns due to
inefficiencies in the marketplace.
     
  .Under normal market conditions, the Fund will invest at least 65% of its
   assets in Equity Securities of companies with market capitalizations below
   $1 billion, which is less than the market capitalization of S&P 500
   companies.

  The Advisor will concentrate on companies that it believes are undervalued.
A company's Equity Securities may be undervalued because the company is
temporarily overlooked or out of favor due to general economic conditions, a
market decline, industry conditions or developments affecting the particular
company. The Fund will usually invest in Equity Securities of companies with
low price/earnings ratios, low price/cash flow ratios and low price/book
values compared to the general market.
 
  In addition to valuation, the Advisor considers these factors, among others,
in choosing companies:
 
  .a stable or improving earnings record
 
  .sound finances
 
  .above-average growth prospects
 
  .participation in a fast growing industry
 
  .strategic niche position in a specialized market
 
  .adequate capitalization.

Key, Chief Investment Officer of the Sub-Advisor, heads the committee.
 
                     WHO MAY WANT TO INVEST IN THE FUNDS?
 
  The Funds are designed for investors who desire potentially high capital
appreciation and who can accept short-term variations in return for
potentially greater returns over the long term. In general, the greater the
risk, the greater the potential reward. Investors who have a short time
horizon, who desire a high level of income or who are conservative in their
investment approach may wish to invest in other portfolios offered by the
Trust and the Company.
 
           WHAT ARE THE FUNDS' INVESTMENTS AND INVESTMENT PRACTICES?
   
  Each Fund invests in EQUITY SECURITIES, which include common stocks,
preferred stocks, warrants and other securities convertible into common
stocks. Many of the common stocks the Funds (other than Growth & Income Fund)
will buy will not pay dividends; instead, stocks will be bought for the
potential that their prices will increase, providing capital appreciation for
the Funds. The value of Equity Securities will fluctuate due to many factors,
including the past and predicted earnings of the issuer, the quality of the
issuer's management, general market conditions, the forecasts for the issuer's
industry and the value of the issuer's assets. Holders of Equity Securities
only have rights to value in the company after all debts have been paid, and
they could lose their entire investment in a company that encounters financial
difficulty. Warrants are rights to purchase securities at a specified time at
a specified price.     
   
  Each Fund may invest in CASH EQUIVALENTS, which are high-quality, short-term
money market instruments including, among other things, commercial paper,
bankers' acceptances and negotiable certificates of deposit of banks or
savings and loan associations, short-term corporate obligations and short-term
securities issued by, or guaranteed by, the U.S. Government and its agencies
or instrumentalities. These instruments will be used primarily pending
investment, to meet anticipated redemptions or as a temporary defensive
measure. If a Fund is investing defensively, it may not be pursuing its
investment objective.     
 
  The Funds may enter into REPURCHASE AGREEMENTS. Under a repurchase
agreement, a Fund agrees to purchase securities from a seller and the seller
agrees to repurchase the securities at a later time, typically within seven
days, at a set price. The seller agrees to set aside collateral at least equal
to the repurchase price. This ensures that the Fund will receive the purchase
price at the time it is due, unless the seller defaults or declares
bankruptcy, in which event the Fund will bear the risk of possible loss due to
adverse market action or delays in liquidating the underlying obligation.
   
  The Funds may purchase ADRS, EUROPEAN DEPOSITARY RECEIPTS ("EDRS") and
GLOBAL DEPOSITARY RECEIPTS ("GDRS"). ADRs are issued by U.S. financial
institutions and EDRs and GDRs are issued by European financial institutions.
They are receipts evidencing ownership of underlying Foreign Securities.

  The Funds may buy shares of registered MONEY MARKET FUNDS. The Funds will
bear a portion of the expenses of any investment company whose shares they
purchase, including operating costs and investment advisory, distribution and
administration fees. These expenses would be in addition to a Fund's own
expenses. Each Fund may invest up to 10% of its assets in other investment
companies and no more than 5% of its assets in any one investment company.
 
  The Funds may purchase FIXED INCOME SECURITIES. Fixed Income Securities are
securities which either pay interest at set times at either fixed or variable
rates, or which realize a discount upon maturity. Fixed Income Securities
include corporate bonds, debentures, notes and other similar corporate debt
instruments, zero coupon bonds (discount debt obligations that do not make
interest payments) and variable amount master demand notes that permit the
amount of indebtedness to vary in addition to providing for periodic
adjustments in the interest rate. Each Fund may purchase U.S. GOVERNMENT
SECURITIES, which are securities issued by, or guaranteed by, the U.S.
Government or its agencies or instrumentalities. Such securities include U.S.
Treasury bills, which have initial maturities of less than one year, U.S.
Treasury notes, which have initial maturities of one to ten years, U.S.
Treasury bonds, which generally have initial maturities of greater than ten
years, and obligations of the Federal Home Loan Mortgage Corporation, Federal
National Mortgage Association and Government National Mortgage Association.
Under normal market conditions, the Funds will not invest to a significant
extent, or on a routine basis, in U.S. Government Securities.
 
  Each Fund may BORROW MONEY in an amount up to 5% of its assets for temporary
purposes and in an amount up to 33 1/3% of its assets to meet redemptions.
This is a "fundamental" policy which can be changed only by shareholders.
   
  All of the Funds, are classified as "diversified funds." With respect to 75%
of each diversified Fund's assets, each diversified Fund cannot invest more
than 5% of its assets in a single issuer (other than the U.S. Government and
its agencies and instrumentalities). In addition, each diversified Fund cannot
invest more than 25% of its assets in a single issuer. These restrictions do
not apply to the non-diversified Funds.

                 WHAT ARE THE RISKS OF INVESTING IN THE FUNDS?
 
  Investing in the Funds may be less risky than investing in individual stocks
due to the diversification of investing in a portfolio of many different
stocks; however, such diversification does not eliminate all risks. Because
the Funds invest mostly in Equity Securities, rises and falls in the stock
market in general, as well as in the value of particular Equity Securities
held by the Funds, can affect the Funds' performance. Your investment in the
Funds is not guaranteed. The net asset value of the Funds will change daily
and you might not recoup the amount you invest in the Funds.
 
  The Funds are not meant to provide a vehicle for playing short-term swings
in the stock market. Consistent with a long-term investment approach,
investors in a Fund should be prepared and able to maintain their investments
during periods of adverse market conditions. By itself, no Fund is a balanced
investment program and there is no guarantee that any Fund will achieve its
investment objective since there is uncertainty in every investment.
   
  A Fund's risk is mostly dependent on the types of securities it purchases
and its investment techniques. Each Fund is authorized to use options,
futures, and forward foreign currency exchange contracts, which are types of
derivative instruments. Derivative instruments are instruments that derive
their value from a different underlying security, index or financial
indicator. The use of derivative instruments exposes a Fund to additional
risks and transaction costs. Risks inherent in the use of derivative
instruments include: (1) the risk that interest rates, securities prices and
currency markets will not move in the direction that a portfolio manager
anticipates; (2) imperfect correlation between the price of derivative
instruments and movements in the prices of the securities, interest rates or
currencies being hedged; (3) the fact that skills needed to use these
strategies are different than those needed to select equity securities; (4)
the possible absence of a liquid secondary market for any particular
instrument and possible exchange imposed price fluctuation limits, either of
which may make it difficult or impossible to close out a position when
desired; (5) leverage risk, that is, the risk that adverse price movements in
an instrument can result in a loss substantially greater than the Fund's
initial investment in that instrument (in some cases, the potential loss is
unlimited); (6) particularly in the case of privately-negotiated instruments,
the risk that the counterparty will not perform its obligations, which could
leave the Fund worse off than if it had not entered into the position; and (7)
inability to close out certain hedged positions to avoid adverse tax
consequences.     
 
  To the extent that a Fund invests in illiquid securities, the Fund risks not
being able to sell securities at the time and the price that it would like. A
Fund may therefore have to lower the price, sell substitute securities or
forego an investment opportunity, each of which might adversely affect the
Fund.
 
  The risks of the various investment techniques the Funds use are described
in more detail in the SAI.
   
 Growth Opportunities Fund, Micro-Cap Equity Fund, NetNet Fund, Small-Cap
 Value Fund and Small Company Growth Fund     
 
  The Advisor believes that smaller companies can provide greater growth
potential and potentially higher returns than larger firms. Investing in
smaller companies, however, is riskier than investing in larger companies. The
stock of smaller companies may trade infrequently and in lower volume, making
it more difficult for a Fund to sell the stocks of smaller companies when it
chooses. Smaller companies may have limited product lines, markets, financial
resources and distribution channels, which makes them more sensitive to
changing economic conditions. Stocks of smaller companies historically have
had larger fluctuations in price than stocks of larger companies included in
the S&P 500.
   
 Framlington Emerging Markets Fund, Framlington Global Financial Services
 Fund, Framlington International Growth Fund and International Equity Fund
     
  Investing in any of these Funds, with their larger investment in Foreign
Securities, may involve more risk than investing in a U.S. fund for the
following reasons: (1) there may be less public information available about
foreign companies than is available about U.S. companies; (2) foreign
companies are not generally subject to the
 
                                      46
<PAGE>
 
uniform accounting, auditing and financial reporting standards and practices
applicable to U.S. companies; (3) foreign stock markets have less volume than
the U.S. market, and the securities of some foreign companies are less liquid
and more volatile than the securities of comparable U.S. companies; (4) there
may be less government regulation of stock exchanges, brokers, listed
companies and banks in foreign countries than in the United States; (5) the
Fund may incur fees on currency exchanges when it changes investments from one
country to another; (6) the Fund's foreign investments could be affected by
expropriation, confiscatory taxation, nationalization of bank deposits,
establishment of exchange controls, political or social instability or
diplomatic developments; (7) fluctuations in foreign exchange rates will
affect the value of the Fund's portfolio securities, the value of dividends
and interest earned, gains and loses realized on the sale of securities, net
investment income and unrealized appreciation or depreciation of investments;
and (8) possible imposition of dividend or interest withholding by a foreign
country.
 
 Framlington Global Financial Services Fund
 
  Financial services companies are subject to extensive governmental
regulation which may limit both the amount and types of loans and other
financial commitments they can make, and the interest rates and fees they can
charge. Profitability is largely dependent on the availability and cost of
capital funds, and can fluctuate significantly when interest rates change.
Credit losses resulting from financial difficulties of borrowers can
negatively impact the industry. Insurance companies may be subject to severe
price competition. Legislation is currently being considered which would
reduce the separation between commercial and investment banking businesses. If
enacted, this could significantly impact the industry and the Fund. The Fund
may be riskier than a fund investing in a broader range of industries.
 
  Although securities of large and well-established companies in the financial
services industry will be held in the Fund's portfolio, the Fund also will
invest in medium, small and/or newly-public companies which may be subject to
greater share price fluctuations and declining growth, particularly in the
event of rapid changes in the industry and/or increased competition.
Securities of those smaller and/or less seasoned companies may, therefore,
expose shareholders of the Fund to above-average risk.
 
 Framlington Healthcare Fund
 
  The Fund will invest most of its assets in the healthcare industry, which is
particularly affected by rapidly changing technology and extensive government
regulation, including cost containment measures. The Fund may be riskier than
a fund investing in a broader range of industries.
 
 NetNet Fund
 
  The Fund will invest primarily in companies engaged in Internet and Intranet
related activities. The value of such companies is particularly vulnerable to
rapidly changing technology, extensive government regulation and relatively
high risks of obsolescence caused by scientific and technological advances.
The value of the Fund's shares may fluctuate more than shares of a fund
investing in a broader range of industries.
 
 Real Estate Equity Investment Fund
 
  The Fund will invest primarily in the real estate industry and may invest
more than 25% of its assets in any one sector of the real estate industry. As
a result, the Fund will be particularly vulnerable to declines in real estate
prices and new construction rates. The Fund may be riskier than a fund
investing in a broader range of industries.
 
                                  PERFORMANCE
 
                   HOW IS THE FUND'S PERFORMANCE CALCULATED?
 
  There are various ways in which the Funds may calculate and report their
performance. Performance is calculated separately for each class of shares.
 
  One method is to show a Fund's total return. Cumulative total return is the
percentage change in the value of an amount invested in a class of shares of a
Fund over a stated period of time and takes into account reinvested dividends
plus in the case of Class A Shares, the payment of the maximum sales charge
and, in the case of Class B
 
                                      47
<PAGE>
 
and Class C Shares, the maximum CDSC. Cumulative total return most closely
reflects the actual performance of a Fund. However, a shareholder who opts to
receive dividends in cash, a Class A shareholder who paid a sales charge lower
than 5.5%, or a Class B or C shareholder who paid lower than the maximum CDSC
will have a different return than the reported performance.
 
  Average annual total return refers to the average annual compounded rates of
return over a specified period on an investment in shares of a Fund determined
by comparing the initial amount invested to the ending redeemable value of the
amount, taking into account reinvested dividends, the payment of the maximum
sales charge on Class A Shares, and the payment of the maximum CDSC on Class B
and Class C Shares.
 
  Each Fund may also publish its current yield. Yield is the net investment
income generated by a share of a Fund during a 30-day period divided by the
maximum offering price on the 30th day. "Maximum offering price" includes the
sales charge for Class A Shares.
 
  The Funds may sometimes publish total returns that do not take into account
sales charges and such returns will be higher than returns which include sales
charges. You should be aware that (i) past performance does not indicate how a
Fund will perform in the future; and (ii) each Fund's return and net asset
value will fluctuate, so you cannot necessarily use a Fund's performance data
to compare it to investment in certificates of deposit, savings accounts or
other investments that provide a fixed or guaranteed yield.
   
  Each Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. Each Fund may also compare its total return
to broad-based indices. These indices show the value of selected portfolios of
securities (assuming reinvestment of interest and dividends) which are not
managed by a portfolio manager. The Funds may report how they are performing
in comparison to the Consumer Price Index, an indication of inflation reported
by the U.S. Government.     
 
                     WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Funds' annual report dated June 30 of each year and semi-
annual report dated December 31 of each year, which will automatically be
mailed to shareholders. To obtain copies of financial reports or performance
information, call (800) 438-5789.
 
                       PURCHASES AND EXCHANGES OF SHARES
 
             WHICH SHARE CLASS SHOULD I CHOOSE FOR MY INVESTMENT?
 
  Each of the Funds offers Class A, Class B and Class C Shares. Each Class has
its own cost structure, allowing you to choose the one that best meets your
requirements given the amount of your purchase and the intended length of your
investment. You should consider both ongoing annual expenses and initial or
contingent deferred sales charges in estimating the costs of investing in a
particular class of shares.

  Each Fund other than the NetNet Fund issues Class K and Class Y Shares,
which have different sales charges, expense levels and performance. The NetNet
Fund offer only Class Y Shares. Class K and Class Y Shares are available to
limited types of investors. Call (800) 438-5789 to obtain more information
concerning Class K and Class Y Shares.
 
                        WHAT PRICE DO I PAY FOR SHARES?
   
  The purchase price for Class A Shares is the net asset value ("NAV") next
determined after we receive your order in proper form PLUS any applicable
sales charge. The purchase price for Class B and Class C Shares is the NAV
next determined after we receive your order in proper form. You should be
aware that broker-dealers (other than the Funds' Distributor) may charge
investors additional fees if shares are purchased through them.     
   
  Except in certain limited circumstances, each Fund determines its NAV on
each day the New York Stock Exchange ("NYSE") is open for trading (a "Business
Day") at the close of such trading on the NYSE (normally 4:00 p.m. Eastern
time). Each Fund calculates NAV separately for each class of shares. NAV is
calculated by totaling the value of all of the assets of a Fund allocated to a
particular class of shares, subtracting the Fund's liabilities and expenses
charged to that class and dividing the result by the number of shares of that
class outstanding.     
   
  APPLICABLE SALES CHARGE. Except in the circumstances described below, you
must pay a sales charge at the time of purchase of Class A Shares. The sales
charge as a percentage of your investment decreases as the amount you invest
increases. The current sales charge rates and commissions paid to selected
dealers are as follows:

*No initial sales charge applies on investments of $1 million or more.
   However, a CDSC of 1% is imposed on certain redemptions within one year of
   purchase. Class A Shares of the Trust Funds purchased on or before June 27,
   1995 are subject to a different CDSC, which is described in the SAI.
**The Distributor will pay a 1% commission to dealers who initiate and are
   responsible for purchases of $1 million or more.
 
  The Distributor may pay the entire commission to dealers. If that occurs,
the dealer may be considered an "underwriter" under Federal securities laws.
 
  SALES CHARGE WAIVERS. We will waive the initial sales charge on sales of
Class A Shares to the following types of purchasers:
 
 (1) individuals with an investment account or relationship with the Advisor;
 
 (2) full-time employees and retired employees of the Advisor, employees of
     the Funds' service providers and immediate family members of such
     persons;
 
 (3) registered broker-dealers that have entered into selling agreements with
     the Distributor, for their own accounts or for retirement plans for their
     employees or sold to registered representatives for full-time employees
     (and their families) that certify to the Distributor at the time of
     purchase that such purchase is for their own account (or for the benefit
     of their families);
 
                                      49

 (4) certain qualified employee benefit plans as described below;
 
 (5) individuals who reinvest a distribution from a qualified retirement plan
     for which the Advisor serves as investment advisor;
 
 (6) individuals who reinvest the proceeds of redemptions from Class Y Shares
     of the Funds of the Trust, the Company or Framlington, within 60 days of
     redemption;
 
 (7) banks and other financial institutions that have entered into agreements
     with the Trust, the Company or Framlington to provide shareholder
     services for customers (including customers of such banks and other
     financial institutions, and the immediate family members of such
     customers);
 
 (8) fee-based financial planners or employee benefit plan consultants acting
     for the accounts of their clients;
 
 (9) employer sponsored retirement plans which are administered by Universal
     Pensions, Inc. ("UPI Plans");
   
(10) employer sponsored 401(k) plans that are administered by Merrill Lynch
     Group Employee Services ("Merrill Lynch Plans") which meet the criteria
     described below under "Qualified Employer Sponsored Retirement Plans";
     and     
   
(11) with respect to subsequent purchases of shares of the NetNet Fund,
     individuals who were shareholders of the NetNet Fund prior to June 1,
     1998.     
 
QUALIFIED EMPLOYER SPONSORED RETIREMENT PLANS
   
  We will waive the initial sales charge on purchases of Class A Shares by
employer sponsored retirement plans that are qualified under Section 401(a) or
Section 403(b) of the Code (each, a "Qualified Employee Benefit Plan") and
that (1) invest $1,000,000 or more in Class A Shares of investment portfolios
offered by the Trust, the Company or Framlington or (2) have at least 75
eligible plan participants. In addition, we will waive the CDSC of 1% charged
on certain redemptions within one year of purchase for Qualified Employee
Benefit Plan purchases that meet the above criteria. A 1% commission will be
paid by the Distributor to dealers and other entities (as permitted by
applicable Federal and state law) who initiate and are responsible for
Qualified Employee Benefit Plan purchases that meet the above criteria. For
purposes of this sales charge waiver, Simplified Employee Pension Plans
("SEPs"), Individual Retirement Accounts ("IRAs"), UPI Plans and Merrill Lynch
Plans are not considered to be Qualified Employee Benefit Plans.     
 
  We also will waive (i) the initial sales charge on Class A Shares on
purchases by UPI Plans for employees participating in an employer-sponsored or
administered retirement program operating under Section 408A of the Code and
(ii) the CDSC of 1% imposed on certain redemptions within one year of purchase
for these accounts. The Distributor will pay a 1% commission to dealers and
others (as permitted by applicable Federal and state law) who initiate and are
responsible for UPI Plan purchases.
 
  We will waive the initial sales charge for all investments by Merrill Lynch
Plans if (i) the Plan is recordkept on a daily valuation basis by Merrill
Lynch Group Employee Services ("Merrill Lynch") and, on the date the plan
sponsor (the "Plan Sponsor") signs the Merrill Lynch Recordkeeping Service
Agreement, the Plan has $3 million or more in assets invested in broker/dealer
funds not advised or managed by Merrill Lynch Asset Management, L.P. ("MLAM")
that are made available pursuant to a Services Agreement between Merrill Lynch
and the Funds' principal underwriter or distributor and in funds advised or
managed by MLAM (collectively, the "Applicable Investments"); or (ii) the Plan
is recordkept on a daily valuation basis by an independent recordkeeper whose
services are provided through a contract or alliance arrangement with Merrill
Lynch, and on the date the Plan Sponsor signs the Merrill Lynch Recordkeeping
Service Agreement, the Plan has $3 million or more in assets, excluding money
market funds, invested in Applicable Investments; or (iii) the Plan has 500 or
more eligible employees, as determined by the Merrill Lynch plan conversion
manager, on the date the Plan Sponsor signs the Merrill Lynch Recordkeeping
Service Agreement.
 
  SALES CHARGE REDUCTIONS. You may qualify for reduced sales charges in the
following cases:
 
  . LETTER OF INTENT. If you intend to purchase at least $25,000 of Class A,
    Class B and Class C Shares of the Funds you may wish to complete the
    Letter of Intent Section of your Account Application Form. By doing so,
    you agree to invest a certain amount over a 13-month period. You would
    pay a sales charge on any
 
                                      50
<PAGE>
 
   Class A Shares you purchase during the 13 months based on the total amount
   to be invested under the Letter of Intent. You can apply any investments
   you made in any of the funds during the preceding 90-day period toward
   fulfillment of the Letter of Intent (although there will be no refund of
   sales charges you paid during the 90-day period). You should inform the
   Transfer Agent that you have a Letter of Intent each time you make an
   investment.
 
     You are not obligated to purchase the amount specified in the Letter of
   Intent. If you purchase less than the amount specified, however, you must
   pay the difference between the sales charge paid and the sales charge
   applicable to the purchases actually made. The Custodian will hold such
   amount in escrow. The Custodian will pay the escrowed funds to your
   account at the end of the 13 months unless you do not complete your
   intended investment.
 
  . QUANTITY DISCOUNTS. You may combine purchases of Class A Shares that are
    made by you, your spouse, your children under age 21 and your IRA when
    calculating the sales charge. You must notify your broker or the Transfer
    Agent to qualify.
 
  . RIGHT OF ACCUMULATION. You may add the value of any shares of non-money
    market funds of the Trust, the Company or Framlington you already own to
    the amount of your next Class A Share investment for purposes of
    calculating the sales charge at the time of current purchase. You must
    notify your broker or the Transfer Agent to qualify.
 
  Certain brokers may not offer these programs or may impose conditions on use
of these programs. You should consult with your broker prior to purchasing the
Funds' shares.
 
  For further information on sales charge waivers and reductions call the
Funds at (800) 438-5789.
 
                          WHEN CAN I PURCHASE SHARES?
 
  Shares of each Fund are sold on a continuous basis and can be purchased on
any Business Day.
 
                   WHAT IS THE MINIMUM REQUIRED INVESTMENT?
 
  The minimum initial investment for Class A, Class B and Class C Shares of a
Fund is $250 and subsequent investments must be at least $50. Purchases in
excess of $250,000 must be for Class A or Class C Shares.
 
                          HOW CAN I PURCHASE SHARES?
 
  You can purchase Class A, Class B and Class C Shares in a number of
different ways. You may place orders directly through the Transfer Agent or
the Distributor or through arrangements with your authorized broker.
 
  . BY BROKER. Any broker authorized by the Distributor can sell you shares
    of the Funds. Please note that brokers may charge you fees for their
    services.
 
  . BY MAIL. You may open an account by completing, signing and mailing the
    attached Account Application Form and a check or other negotiable bank
    draft (payable to The Munder Funds) for $250 or more to: THE MUNDER
    FUNDS, C/O FIRST DATA INVESTOR SERVICES GROUP, P.O. BOX 5130,
    WESTBOROUGH, MASSACHUSETTS 01581-5130. Be sure to specify on your Account
    Application Form the class of shares being purchased. If the class is not
    specified, your purchase will automatically be invested in Class A
    Shares. For additional investments send a letter stating the Fund and
    share class you wish to purchase, your name and your account number with
    a check for $50 or more to the address listed above.
 
  . BY WIRE. To open a new account, you should call the Funds at (800) 438-
    5789 to obtain an account number and complete wire instructions prior to
    wiring any funds. Within seven days of purchase, you must send a
    completed Account Application Form containing your certified taxpayer
    identification
 
                                      51
<PAGE>
 
   number to the Transfer Agent at the address provided above. Wire
   instructions must state the Fund name, share class, your registered name
   and your account number. Your bank wire should be sent through the Federal
   Reserve Bank Wire System to:
 
                     Boston Safe Deposit and Trust Company
                        Boston, MA
                        ABA# 011001234
                        DDA# 16-798-3
                        Account No.:
 
   You may make additional investments at any time using the wire procedures
   described above. Note that banks may charge fees for transmitting wires.
 
  . AUTOMATIC INVESTMENT PLAN ("AIP"). Under the AIP you may arrange for
    periodic investments in a Fund through automatic deductions from a
    checking or savings account. To enroll in the AIP you should complete the
    AIP Application Form or call the Funds at (800) 438-5789. The minimum
    pre-authorized investment amount is $50. You may discontinue the AIP at
    any time. We may discontinue the AIP on 30 days' written notice to you.
 
  . REINVESTMENT PRIVILEGE. Once a year you may reinvest redemption proceeds
    from Class A, B and C Shares of a Fund (or Class A, B and C Shares of
    another non-money market fund of the Trust, the Company or Framlington)
    in shares of the same class of the same Fund without any sales charges,
    if the reinvestment is made within 60 days of redemption. You or your
    broker must notify the Transfer Agent in writing at the time of
    reinvestment in order to eliminate the sales charge.
 
  The Transfer Agent will send you confirmations of the opening of an account
and of all subsequent purchases, exchanges or redemptions in the account. If
your account has been set up by a broker or other investment professional,
account activity will be detailed in their statements to you.
 
  We do not issue share certificates. We reserve the right to (i) reject any
purchase order if, in our opinion, it is in the Funds' best interest to do so
and (ii) suspend the offering of shares of any class for any period of time.
 
  See the SAI for further information regarding purchases of the Funds'
shares.
 
                          HOW CAN I EXCHANGE SHARES?
   
  You may exchange shares of the Funds for shares of the same class of other
funds of the Trust, the Company or Framlington based on their relative net
asset values. Class A Shares of a money market fund of the Trust or the
Company that were (1) acquired through the use of the exchange privilege and
(2) can be traced back to a purchase of shares in one or more funds of the
Trust or the Company for which a sales charge was paid, can be exchanged for
Class A Shares of a fund of the Trust, the Company or Framlington. Class B and
Class C Shares will continue to age from the date of the original purchase and
will retain the same CDSC rate as they had before the exchange.     
 
  You must meet the minimum purchase requirements for the fund of the Trust,
the Company or Framlington that you purchase by exchange. If you are
exchanging into shares of a fund with a higher sales charge, you must pay the
difference at the time of the exchange. Please note that a share exchange is a
taxable event and accordingly, you may realize a taxable gain or loss. Before
making an exchange request, read the Prospectus of the fund you wish to
purchase by exchange. You can obtain a Prospectus for any fund of the Trust,
the Company or Framlington by contacting your broker or the Funds at (800)
438-5789. Brokers may charge a fee for handling exchanges.
 
  . EXCHANGES BY TELEPHONE. You may give exchange instructions by telephone
    to the Funds at (800) 438-5789. You may not exchange shares by telephone
    if you hold share certificates. We reserve the right to reject any
    telephone exchange request and to place restrictions on telephone
    exchanges.
 
                                      52

  . EXCHANGES BY MAIL. You may send exchange orders to your broker or to the
    Transfer Agent at The Munder Funds c/o First Data Investor Services
    Group, P.O. Box 5130, Westborough, Massachusetts 01581-5130.     
 
  We may modify or terminate the exchange privilege at any time. You will be
given notice of any material modifications except where notice is not
required.
 
                             REDEMPTIONS OF SHARES
                  
               WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?     
   
  The redemption price is the NAV next determined after we receive the
redemption request in proper form. We will reduce the amount you receive by
the amount of any applicable CDSC. See "Purchases of Shares--What Price Do I
Pay for Shares?" for an explanation of how the net asset value next determined
is calculated.     
 
  CONTINGENT DEFERRED SALES CHARGES. You pay a CDSC when you redeem:
 
  . Class A Shares that are part of an investment of at least $1 million
    within one year of buying them
 
  . Class B Shares within six years of buying them
 
  . Class C Shares within one year of buying them.
 
  These time periods include the time you held Class B or Class C Shares which
you may have exchanged for Class B or Class C Shares of the Fund.
   
  The CDSC schedule for Class B Shares purchased after June 27, 1995 is set
forth below. See the SAI for the CDSC schedule for Class B Shares purchased
before that time. The CDSC is based on the original net asset value at the
time of your investment or the net asset value at the time of redemption,
whichever is lower.

  The Distributor pays sales commissions of 4.00% of the purchase price of
Class B Shares of the Funds to brokers at the time of sale that initiate and
are responsible for purchases of such Class B Shares of the Funds.
 
  You will not pay a CDSC to the extent that the value of the redeemed shares
represents:
 
  . reinvestment of dividends or capital gains distributions
 
  . capital appreciation of shares redeemed.
 
  When you redeem shares, we will assume that you are redeeming first shares
representing reinvestment of dividends and capital gains distributions, then
any appreciation on shares redeemed, and then remaining shares held by you for
the longest period of time. We will calculate the holding period of shares of
a Fund acquired through an exchange of shares of the Munder Money Market Fund
from the date that the shares of the Fund were initially purchased.

  CDSC WAIVERS. We will waive the CDSC payable upon redemptions of shares
which you purchased after June 27, 1995 for:
 
  . redemptions made within one year after the death of a shareholder or
    registered joint owner
 
  . minimum required distributions made from an IRA or other retirement plan
    account after you reach age 70 1/2
 
  . involuntary redemptions made by the Fund
 
  . redemptions limited to 10% per year of an account's NAV. For example, if
    you maintain an annual balance of $10,000 you can redeem up to $1,000
    annually free of charge.
 
  Consult the SAI for Class B Share CDSC waivers which apply when you redeem
shares acquired in an exchange of shares of another Fund of the Company or the
Trust that were purchased on or before June 27, 1995.
 
  We will waive the CDSC for Class B Shares for all redemptions by Merrill
Lynch Plans if: (i) the Plan is recordkept on a daily valuation basis by
Merrill Lynch; or (ii) the Plan is recordkept on a daily valuation basis by an
independent recordkeeper whose services are provided through a contract or
alliance arrangement with Merrill Lynch; or (iii) the Plan has less than 500
eligible employees, as determined by the Merrill Lynch plan conversion
manager, on the date the Plan Sponsor signs the Merrill Lynch Recordkeeping
Service Agreement.
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. A Fund may temporarily stop
redeeming shares when the NYSE is closed or trading on the NYSE is restricted,
when an emergency exists and the Fund cannot sell its assets or accurately
determine the value of its assets or if the SEC orders the Fund to suspend
redemptions.
 
                           HOW CAN I REDEEM SHARES?
 
  You may redeem shares of the Funds in several ways:
     
  . BY MAIL. You may mail your redemption request to: THE MUNDER FUNDS, C/O
    FIRST DATA INVESTOR SERVICES GROUP, P.O. BOX 5130, WESTBOROUGH,
    MASSACHUSETTS 01581-5130. The redemption request should state the name of
    the Fund, share class, account number, amount of redemption, account name
    and where to send the proceeds. All account owners must sign. If a share
    certificate has been issued to you, you must endorse the share
    certificate and return it together with the written redemption request.
        
     A SIGNATURE GUARANTEE is required for the following redemption
   requests: (a) redemptions proceeds greater than $50,000; (b) redemption
   proceeds not being made payable to the owner of the account; (c)
   redemption proceeds not being mailed to the address of record on the
   account or (d) if the redemption proceeds are being transferred to
   another Munder Funds account with a different registration. You can
   obtain a signature guarantee from a financial institution such as a
   commercial bank, trust company, savings association or from a securities
   firm having membership on a recognized securities exchange.
 
  . BY TELEPHONE. You can redeem your shares by calling your broker or the
    Funds at (800) 438-5789. There is no minimum requirement for telephone
    redemptions paid by check. The Transfer Agent may deduct a wire fee
    (currently $7.50) for wire redemptions under $5,000.
 
     If you are redeeming at least $1,000 of shares and you have authorized
   expedited redemption on your Account Application Form, simply call the
   Fund prior to 4:00 p.m. (Eastern Time), and request the funds be mailed
   to the commercial bank or registered broker-dealer you designated on your
   Account Application Form. We will send your redemption amount to you on
   the next Business Day. We reserve the right at any time to change or
   impose fees for this expedited redemption procedure.
 
                                      54
<PAGE>
 
     We record all telephone calls for your protection and take measures to
   identify the caller. If the Transfer Agent properly acts on telephone
   instructions and follows the reasonable procedures to ensure against
   unauthorized transactions, neither the Trust, the Company, the
   Distributor nor the Transfer Agent will be responsible for any losses. If
   these procedures are not followed, the Transfer Agent may be liable to
   you for losses resulting from unauthorized instructions.
 
     During periods of unusual economic or market activity, you may
   experience difficulties or delays in effecting telephone redemptions. In
   such cases you should consider placing your redemption request by mail.
 
  . AUTOMATIC WITHDRAWAL PLAN ("AWP"). If you have an account value of $2,500
    or more in a Fund, you may redeem shares on a monthly, quarterly, semi-
    annual or annual basis. The minimum withdrawal is $50. We usually process
    withdrawals on the 20th day of the month and promptly send you your
    redemption amount. You may enroll in the AWP by completing the AWP
    Application Form available through the Transfer Agent. To participate in
    the AWP you must have your dividends automatically reinvested and may not
    hold share certificates. You may change or cancel the AWP at any time
    upon notice to the Transfer Agent. You should not buy Class A Shares (and
    pay a sales charge) while you participate in the AWP and you must pay any
    applicable CDSC's when you redeem shares.
 
  . INVOLUNTARY REDEMPTION. We may redeem your account if its value falls
    below $250 as a result of redemptions (but not as a result of a decline
    in net asset value). You will be notified in writing and allowed 60 days
    to increase the value of your account to the minimum investment level.
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  We will typically send redemption amounts to you within seven Business Days
after you redeem shares. We may hold redemption amounts from the sale of
shares you purchased by check until the purchase check has cleared, which may
be as long as 15 days.
 
                     STRUCTURE AND MANAGEMENT OF THE FUNDS
 
                         HOW ARE THE FUNDS STRUCTURED?
 
  The Trust, the Company and Framlington are each an open-end management
investment company, which is a mutual fund that sells and redeems shares every
day that it is open for business. They are managed under the direction of
their governing Boards of Trustees and Directors, which are responsible for
the overall management of the Trust, the Company and Framlington and supervise
the Funds' service providers. The Trust and Framlington are organized as
Massachusetts business trusts and the Company is a Maryland corporation.
 
                      WHO MANAGES AND SERVICES THE FUNDS?
   
  INVESTMENT ADVISOR AND SUB-ADVISOR. The Funds' investment advisor is Munder
Capital Management, a Delaware general partnership with its principal offices
at 480 Pierce Street, Birmingham, Michigan 48009. The principal partners of
the Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM
Holdings II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware
corporation and was a registered investment advisor. WAM and WAM II are
Delaware corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,
1998, the Advisor and its affiliates had approximately $48.2 billion in assets
under management, of which $25.4 billion were invested in equity securities,
$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion
in non-discretionary assets.     
 
  The Advisor provides overall investment management and research and credit
analysis for each Fund and is responsible for all purchases and sales of
portfolio securities for each Fund other than the Framlington Funds.
 
 
                                      55
<PAGE>
 
  Framlington Overseas Investment Management Limited is the sub-advisor of the
Framlington Funds. The Sub-Advisor is an indirect subsidiary of Framlington
Holdings Limited which is, in turn, owned 49% by the Advisor and 51% by Credit
Commercial de France S.A., a French banking corporation listed on the Societe
des Bourses Francaises.
 
  The Sub-Advisor provides research and credit analysis for each of the
Framlington Funds and is responsible for all purchase and sales of portfolio
securities for each of the Framlington Funds other than the Framlington Global
Financial Services Fund. Each of the Advisor and Sub-Advisor manages a portion
of the assets of the Framlington Global Financial Services Fund. The Advisor
is responsible for all purchases and sales of domestic securities held by the
Fund. The Sub-Advisor is responsible for the allocation of the Fund's assets
among countries and for all purchases and sales of foreign securities held by
the Fund.
 
  During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate based on the average daily net assets of each Fund
(after waivers, if any) as follows:

  The Advisor is entitled to receive an annual fee equal to 1.00% of the first
$500 million of the Multi-Season Growth Fund's average daily net assets and
 .75% of the Fund's average daily net assets over $500 million. During the past
fiscal year, the Advisor waived advisory fees for the Multi- Season Growth
Fund.     
   
   During the fiscal year ended June 30, 1998, the Sub-Advisor received an
advisory fee equal to one half of the fee paid to the Advisor by each of the
Framlington Funds as compensation for its services as Sub-Advisor. The Advisor
pays fees to the Sub-Advisor and the Framlington Funds pay no fees directly to
the Sub-Advisor.     
   
  The Advisor may, from time to time, make payments to banks, broker-dealers
or other financial institutions for certain services to the Funds and/or their
shareholders, including sub-administration, sub-transfer agency and
shareholder servicing. The Advisor may make such payments out of its own
resources and there are no additional costs to the Funds or their
shareholders.     
   
  The Advisor or Sub-Advisor, in the case of the Framlington Funds, selects
broker-dealers to execute portfolio transactions for the Funds based on best
price and execution terms. The Advisor or Sub-Advisor may consider as a factor
the number of shares sold by the broker-dealer.     
 
PERFORMANCE OF FRAMLINGTON FUNDS MANAGED BY THE SUB-ADVISOR
 
  The tables below contain certain performance information provided by the
Sub-Advisor relating to accounts managed by the Sub-Advisor and which have
investment objectives and policies similar to those of the corresponding
Framlington Funds. See "Fund Choices" and "What are the Funds' Investments and
Investment Practices?" In the case of the Healthcare portfolio performance,
the data relates to a unit trust organized under the laws of the United
Kingdom managed by the same personnel of the Sub-Advisor with similar
investment objectives and policies to the Framlington Healthcare Fund. In the
case of Emerging Markets portfolio performance, the data relates to a
Canadian-based institutional emerging markets portfolio managed by the same
personnel of the Sub-Advisor with similar investment objectives and policies
to the Framlington Emerging Markets Fund.
   
  The trust account performance is provided by Standard & Poor's Micropal, an
independent research organization that is a recognized source of performance
data in the UK unit trust industry. The data is U.S. dollar     
 
                                      56
<PAGE>
 
adjusted on the basis of exchange rates provided by Datastream using
WM/Reuters closing rates. The performance figures are net of brokerage
commissions, actual investment advisory fees and initial sales charges. The
data assume the reinvestment of net income and capital gain distributions. The
trust account returns are calculated using beginning offer and ending bid
prices for periods ended December 31, 1996.
 
  You should not rely on the following performance data of the Sub-Advisor's
client accounts as an indication of future performance of the Framlington
Funds. It should be noted that the management of the Funds will be affected by
regulatory requirements under the Investment Company Act of 1940, as amended
(the "1940 Act") and requirements of the Internal Revenue Code of 1986, as
amended, to qualify as a regulated investment company.

INDICES
 
 
  The S&P Healthcare Composite Index is the composite Healthcare section of
the S&P 500 Index as defined and tracked by S&P. This index covers securities
listed in the United States only.
 
  The MSCI Emerging Markets Free Index is maintained by Morgan Stanley Capital
International and covers 26 countries and represents the investment
opportunities in emerging markets available to foreign investors. Total return
is calculated using the prices of the companies tracked and assumes the
reinvestment of dividends.
   
  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Funds'
transfer agent. The Transfer Agent is a wholly owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
01581-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Funds' administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Company, the Trust and Framlington in all aspects of its administration
and operations including
 
                                      57
<PAGE>
 
overseeing the maintenance of financial records and fund accounting. As
compensation for its services for the Company, the Trust and Framlington,
State Street is entitled to receive fees, based on the aggregate daily net
assets of the Funds and certain other investment portfolios that are advised
by the Advisor for which it provides services, computed daily and payable
monthly at the annual rate of 0.113% on the first $2.8 billion of net assets,
plus 0.103% on the next $2.2 billion of net assets, plus 0.101% on the next
$2.5 billion of net assets, plus 0.095% on the next $2.5 billion of net
assets, plus 0.080% on the next $2.5 billion of net assets, plus 0.070% on all
net assets in excess of $12.5 billion (with a $75,000 minimum fee per annum in
the aggregate for all portfolios with respect to the Administrator). If the
assets of the Framlington Funds do not exceed $120 million, the ultimate rate
charged the Framlington Funds will be reduced by their pro-rata portion of the
total fees if calculated at the rates of 0.062% of the first $2.8 billion of
net assets, plus 0.052% of the next $2.2 billion of net assets, plus 0.050% of
all net assets in excess of $5 billion.
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Funds. State Street pays the Distributor a fee
for these services out of its own resources at no cost to the Funds.
 
  CUSTODIAN AND SUB-CUSTODIAN. Comerica Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Funds' custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Funds beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Funds. State Street serves as the Funds' sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Funds' shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Funds' shares.
 
  For an additional description of the services performed by the
Administrator, the Transfer Agent, the Custodian, the Sub-Custodian and the
Distributor, see the SAI.
   
  YEAR 2000. The Funds' operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Funds. The Funds have been
informed that their major service providers have made compliance with the Year
2000 Issue a high priority and are taking steps that they believe are
reasonably designed to address the Year 2000 Issue with respect to their
computer systems. There can be, however, no assurance that these steps will be
successful, or that interaction with other non-complying computer systems will
not impair their services at that time.     
 
DISTRIBUTION SERVICES ARRANGEMENT
 
  Under Rule 12b-1 of the 1940 Act, the Funds have adopted Service Plans with
respect to their Class A Shares and Service and Distribution Plans with
respect to their Class B and Class C Shares. Under the Plans, each Fund uses
its assets to finance activities relating to the distribution of its shares to
investors and the provision of certain shareholder services. The Distributor
is paid a service fee at an annual rate of up to 0.25% of the value of average
daily net assets of the Funds' Class A Shares. The Distributor also is paid a
service fee at an annual rate of 0.25% and a distribution fee at an annual
rate of up to 0.75% of the value of the average daily net assets of the Funds'
Class B and Class C Shares. The Distributor uses the service fees primarily to
pay ongoing trail commissions to securities dealers (which may include the
Distributor itself) and other financial organizations which provide
shareholder services for the Funds. These services include, among other
things, processing new shareholder account applications, reporting to the
Fund's Transfer Agent all transactions by customers and serving as the primary
information source to customers concerning the Funds.

<PAGE>
 
                     WHAT ARE MY RIGHTS AS A SHAREHOLDER?
   
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
the Trust, the Company or Framlington as a whole and affecting your particular
Fund. You will not vote by class unless expressly required by law or when the
Trustees or Directors determine the matter to be voted on affects only the
interests of the holders of a particular class of shares. The Trust, the
Company and Framlington will not hold annual shareholder meetings, but special
meetings may be held at the written request of shareholders owning more than
10% of outstanding shares for the purpose of removing a Trustee or Director.
Under Massachusetts law, it is possible that a shareholder may be personally
liable for the Trust's or Framlington's obligations. If a shareholder were
required to pay a debt of a Fund, however, the Trust and Framlington have
committed to reimburse the shareholder in full from their assets. The SAI
contains more information regarding voting rights.     
 
  Comerica currently has the right to vote a majority of the outstanding
shares of the Funds as agent, custodian or trustee for its customers and
therefore it is considered to be a controlling person of the Trust, the
Company and Framlington.
 
                      DIVIDENDS, DISTRIBUTIONS AND TAXES
 
               WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUNDS?
   
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on a Fund's investments. The Funds pass their earnings along to
investors in the form of dividends. Dividend distributions are the dividends
or interest earned on investments after expenses. The Balanced Fund, Growth &
Income Fund, Index 500 Fund and Small Company Growth Fund pay dividends
quarterly. The Framlington Emerging Markets Fund, Framlington Healthcare Fund,
Framlington International Growth Fund, Framlington Global Financial Services
Fund, International Equity Fund, Growth Opportunities Fund, Micro-Cap Equity
Fund, Multi-Season Growth Fund, NetNet Fund, Small-Cap Value Fund and Value
Fund pay dividends annually. The Real Estate Equity Investment Fund pays
dividends monthly. Each Fund distributes its net realized capital gains
(including net short-term capital gains), if any, at least annually.     
 
  It is possible that a Fund may make a distribution in excess of the Fund's
current and accumulated earnings and profits. You will treat such a
distribution as a return of capital which is applied against and reduces your
basis in your shares. You will treat the excess of any such distribution over
your basis in your shares as gain from a sale or exchange of the shares.
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Funds will pay dividend and capital gains distributions in additional
shares of the same class of a Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Funds at (800) 438-5789.
 
          ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUNDS?
   
  This section contains a brief summary of the tax implications of ownership
in the Funds' shares. A more detailed discussion about the tax treatment of
distributions from the Funds and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Funds, is contained in the SAI. You should
consult your tax advisor regarding the impact of owning the Funds' shares on
your own personal tax situation including the applicability of any state and
local taxes.     
   
  In general, as long as each Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. Each Fund intends to
qualify annually as a RIC. Even if it qualifies as a RIC, a Fund may still be
liable for any excise tax on income that is not distributed in accordance with
a calendar year requirement; the Funds intend to avoid the excise tax by
making timely distributions.     
 
                                      59
<PAGE>
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains derived from sales of portfolio securities held by a Fund will
generally be designated as long-term or short-term. Distributions from a
Fund's long-term capital gains are generally taxed at the long-term capital
gains rate regardless of how long you have owned shares in the Fund. Dividends
from other sources are generally taxed as ordinary income.
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from each Fund in which
you are a shareholder a statement of the amount and nature of the
distributions made to you during the year.
 
  If you redeem, transfer or exchange Fund shares, you may have taxable gain
or a loss. If you hold Fund shares for six months or less, and during that
time you receive a capital gain dividend, any loss you realize on the sale of
these Fund shares will be treated as a long-term loss to the extent of the
earlier distribution.
 
  Dividends and certain interest income earned from foreign securities by a
Fund may be subject to foreign withholding or other taxes. A Fund may be
permitted to pass on to its shareholders the right to a credit or deduction
for income or other tax credits earned from foreign investments and it intends
to do so if possible. These deductions or credits may be subject to tax law
limitations.
 
  If a Fund invests in certain "passive foreign investment companies"
("PFICs"), it will be subject to Federal income tax (and possibly additional
interest charges) on a portion of any "excess distribution" or gain from the
disposition of such shares, even if it distributes such income to its
shareholders. If a Fund elects to treat PFIC as a "qualified electing fund"
("QEF") and the PFIC furnishes certain financial information in the required
form to such Fund, the Fund will instead be required to include in income each
year its allocable share of the ordinary earnings and net capital gains of the
QEF, regardless of whether received, and such amounts will be subject to the
various distribution requirements described above. The Funds may also elect to
mitigate the tax effects of owning PFIC stock by making an annual mark-to-
market election with respect to PFIC shares.
 
                            ADDITIONAL INFORMATION
   
  SHAREHOLDER COMMUNICATIONS. You will receive unaudited Semi-Annual Reports

By signing the application, I(we) hereby certify under the penalty of perjury
that the information on this application is true, complete and correct and that:

I(We) understand that this order is subject to acceptance by The Munder Funds.

I(We) agree that The Munder Funds, Funds Distributor, Inc., First Data, Munder
Capital Management or any of its affiliates, officers, directors or employees
will not be liable for any loss, expense or cost for acting upon instructions or
inquiries reasonably believed to be genuine. Shares of the Funds are not insured

Board, or any other agency. An investment in the Funds involves investment
risks, including the possible loss of principal.

I(We) represent that I am (we are) of legal age and capacity and have read the
Prospectus(es) for The Munder Funds selected, and agree to its (their) terms.
First Data, is hereby appointed agent to receive dividends and distributions for
automatic reinvestment unless otherwise directed in Section 4.

I(We) understand and acknowledge that a sales charge may be levied against the
dollars that I(we) invest in The Munder Funds. (See the Prospectus(es) for
reduced sales charge information.)

The Internal Revenue Service requires that all taxpayers provide their Taxpayer
Identification Numbers (Social Security Numbers) and sign in the space provided
below. Failure by non-exempt taxpayers to furnish us with the correct Taxpayer
Identification Number will result in withholding of 31% of all taxable dividends
paid and/or withholding on certain other payments (this is referred to as backup
withholding).


- --------------------------------------------------------------------------------
Taxpayer Identification Number    Name of Taxpayer Whose Number Appears Above


Taxpayer Identification:

I (the Investor) certify under penalties of perjury that:

(1)  The Social Security Number or taxpayer identification number shown above is
     correct and may be used for any custodial or trust account opened for me by
     The Munder Funds, and

(2)  I (the Investor) am not subject to backup withholding because:

     (a) I am exempt from Backup Withholding

     (b) I have not been notified by the Internal Revenue Service ("IRS") that
         I am, as a result of failure to report all interest or dividends, or

     (c) the IRS has notified me that I am no longer subject to backup
         withholding.

The certification in this paragraph is required from all non-exempt persons to
prevent backup withholding of 31% of all taxable distributions and gross
redemption proceeds under the Federal income tax law.

[_] Check here if you are subject to backup withholding or have not received a
    notice from the IRS advising you that backup withholding has been
    terminated.

                  WHAT ARE THE KEY FACTS REGARDING THE FUNDS?
 
Q: What are the Funds' goals?
 
A:
    
 . The Framlington Emerging Markets Fund, Framlington Global Financial
   Services Fund, Framlington Healthcare Fund, Framlington International
   Growth Fund, Growth Opportunities Fund, International Equity Fund, Micro-
   Cap Equity Fund, Multi-Season Growth Fund, Small-Cap Value Fund, Small
   Company Growth Fund and Value Fund primarily seek to provide long-term
   capital appreciation.

   comparable to the Standard & Poor's 500 Composite Stock Price Index ("S&P
   500").
 
 . The Balanced Fund, Growth & Income Fund and Real Estate Equity Investment
   Fund seek to provide capital appreciation and current income.
 
 . The Bond Fund seeks to provide a high level of current income with capital
   appreciation as a secondary consideration.
 
 . The Intermediate Bond Fund seeks to provide a competitive rate of return
   which exceeds the inflation rate and the return provided by money market
   instruments.

   through a combination of current income and capital appreciation.

   Michigan state income tax as is consistent with prudent investment
   management and preservation of capital.

Q: What are the Funds' strategies?
 
A: BALANCED FUND
 
 . This Fund allocates its assets primarily among three types of assets--
   Equity Securities, Fixed Income Securities and Cash Equivalents. "Equity
   Securities" include common stocks, preferred stocks, warrants and other
   securities convertible into common stock. "Fixed Income Securities" are
   securities which either pay interest at set times at either fixed or
   variable rates, or which realize a discount upon maturity. Fixed Income
   Securities include corporate bonds, debentures, notes and other similar
   corporate debt instruments, zero coupon bonds (discount debt obligations
   that do not make interest payments) and variable amount master demand
   notes that permit the amount of indebtedness to vary in addition to
   providing for periodic adjustments in the interest rates. "Cash
   Equivalents" are instruments which are highly liquid and virtually free of
   investment risk.

   the securities of at least 80% of the issuers in the S&P 500. The Fund is

   attempts to duplicate the investment composition and performance of the

   instrumentalities and authorities, the interest on which is exempt from
   regular Federal income tax.

   Obligations. "Michigan Municipal Obligations" are municipal obligations

                                            funds since such companies
                                            typically have greater earnings

*  The Advisor expects to voluntarily waive a portion of its advisory fees for
   the current fiscal year. Without waiver, the ratio of advisory fees to
   average net assets would be .93% for the Multi-Season Growth Fund and .13%
   for the Index 500 Fund and total fund operating expenses would be 1.39% for
   the Multi-Season Growth Fund and .60% for the Index 500 Fund. The Advisor
   may discontinue such voluntary waivers at any time in its sole discretion.
       
+  After expense reimbursements, if any.
   
++ The Advisor expects to voluntarily reimburse the Funds for certain
   operating expenses. In the absence of such expense reimbursements, the
   total fund operating expenses would be as follows: 2.14% for Framlington
   Emerging Markets Fund, 2.40% for the Framlington Healthcare Fund, 1.82% for
   Framlington International Growth Fund and 1.78% for the Micro-Cap Equity
   Fund; and it is estimated the total fund operating expenses would be 1.41%
   for the Growth Opportunities Fund and 1.57% for the Framlington Global
   Financial Services Fund. The Advisor may discontinue such voluntary expense
   reimbursements at any time in its sole discretion.

                            WHAT FUNDS ARE OFFERED?
 
  This Prospectus offers Class K Shares of the Funds described below. This
section summarizes each Fund's principal investments. The sections entitled
"What are the Funds' Investments and Investment Practices?" and "What are the
Risks of Investing in the Funds?" and the SAI give more information about the
Funds' investment techniques and risks. Capitalized terms are explained in the
section entitled "What are the Funds' Investments and Investment Practices?"
       
                                 BALANCED FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide an attractive
investment return through a combination of growth of capital and current
income. The Fund will allocate its assets among three asset groups: Equity
Securities, Fixed Income Securities and Cash Equivalents.
 
  . The Fund normally will invest at least 25% of its assets in Fixed Income
    Securities and no more than 75% of its assets in Equity Securities. The
    Fund will notify shareholders at least 30 days before changing this
    policy.
 
  The Advisor will allocate the Fund's assets to the three asset groups based
on its view of the following factors, among others:
 
  . general market and economic conditions and trends
 
  . interest rates and inflation rates
 
  . fiscal and monetary developments
 
  . long-term corporate earnings growth.
 
  The Advisor will try to take advantage of changing economic conditions by
adjusting the ratio of Equity Securities to Fixed Income Securities or Cash
Equivalents. For example, if the Advisor believes that rapid economic growth
will lead to better corporate earnings in the future, then it might increase
the Fund's Equity Securities holdings and reduce its Fixed Income Securities
and Cash Equivalents holdings.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                             GROWTH & INCOME FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide capital
appreciation and current income. It primarily invests in dividend-paying
Equity Securities and is designed for investors seeking current income and
capital appreciation from the equity markets.
 
  . Under normal circumstances, the Fund will invest at least 65% of its
    assets in income-producing common stocks and convertible preferred
    stocks.
 
  . The Fund may also purchase Fixed Income Securities which are convertible
    into or exchangeable for common stock.
 
  . The Fund may invest up to 35% of its assets in Fixed Income Securities,
    including 20% of its assets in Fixed Income Securities that are rated
    below investment grade.
 
  The Advisor generally selects large, well-known companies that it believes
have favorable prospects for dividend growth and capital appreciation. The
Fund will seek to produce a current yield greater than the S&P 500.
 
                                      30
<PAGE>
 
  The Fund focuses on dividend-paying Equity Securities because, over time,
dividend income has accounted for a significant portion of the total return of
the S&P 500. In addition, dividends are usually a more stable and predictable
source of return than capital appreciation. The Advisor believes that stocks
which distribute a high level of current income generally have more stable
prices than those which pay below average dividends.
 
  PORTFOLIO MANAGEMENT. Otto Hinzmann, Jr. is the Fund's portfolio manager, a
position he has held since February 1995. Mr. Hinzmann has been a Vice
President and Director of Equity Management of the Advisor or Old MCM, Inc.
("MCM"), the predecessor to the Advisor, since January 1987.
 
                           GROWTH OPPORTUNITIES FUND
   
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. The Fund invests at least 65% of its assets in the
Equity Securities of companies with market capitalizations between $500
million and $10 billion. Its style, which focuses on both growth prospects and
valuation, is known as GARP (Growth at a Reasonable Price) and seeks to
produce attractive returns during various market environments.     
 
  The Advisor chooses the Fund's investments as follows: The Advisor reviews
the earnings growth of approximately 10,000 companies over the past three
years. It invests in approximately 50 to 100 companies based on:
 
  . superior earnings growth
 
  . financial stability
 
  . relative market value
 
  . price changes compared to the Standard & Poor's MidCap 400 Index.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                                INDEX 500 FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide performance
and income that is comparable to the S&P 500. The S&P 500 is an index of 500
stocks which emphasize large capitalization companies. See Appendix A for more
information on the S&P 500. The Fund will normally hold the securities of at
least 400 of the stocks in the S&P 500.
 
  The Fund will try to achieve a correlation between the performance of its
portfolio and that of the S&P 500 of at least .95. A correlation of 1.0 would
mean that changes in the Fund's price mirror exactly changes in the S&P 500.
The timing of purchases and redemptions, changes in securities markets, level
of the Fund's assets and other factors affect the Fund's ability to exactly
track the S&P 500's performance.
 
  The Fund is managed through the use of a "quantitative" investment approach
and tries to mirror the composition and performance of the S&P 500 through
statistical procedures. The Advisor does not use traditional methods of fund
investment management, i.e., it does not select stocks on the basis of
economic, financial and market analysis. Because the Fund pays brokerage costs
and other fees, its return may be lower than that of the S&P 500.
 
  PORTFOLIO MANAGEMENT. Todd B. Johnson and Kenneth A. Schluchter III jointly
manage the Fund. Mr. Johnson, a Chief Investment Officer of the Advisor, has
served as the portfolio manager of the Fund since July 1992. Mr. Schluchter,
who has managed the Fund since June 1997, was previously a Systems Developer
and Data Analyst for Compuware Incorporated (1993-1995) and a Business Analyst
for Central Transport Incorporated (1989-1993).

                           INTERNATIONAL EQUITY FUND
   
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. The Fund invests primarily in Foreign Securities and
American Depositary Receipts ("ADRs"). At least once a quarter, the Advisor
creates a list of Foreign Securities and ADRs (the "Securities List") which
the Fund may purchase based on the country where the company is located, its
competitive advantages, its past financial record, its future prospects for
growth and the market for its securities. The Advisor updates the Securities
List frequently (at least quarterly), adds new securities to the Securities
List if they are eligible and sells securities not on the updated Securities
List as soon as practicable.     
   
  After the Advisor creates the Securities List, it divides the list into two
sections. The first section is designed to provide broad coverage of
international markets. The second section increases exposure to securities
that the Advisor expects will perform better than other stocks in their
industry sectors and their markets as a whole. When the Advisor believes
broader market exposure will benefit the Fund, it will allocate up to 100% of
the Fund's assets in first section securities. When the Advisor identifies
strong potential for specific securities to perform well, the Fund may invest
up to 50% of its assets in second section securities.     
 
  . Under normal market conditions, at least 65% of the Fund's assets are
    invested in Equity Securities in at least three foreign countries.
     
  . The Fund emphasizes companies with a market capitalization of at least
    $250 million.     
 
  PORTFOLIO MANAGEMENT. Todd B. Johnson and Theodore Miller jointly manage the
Fund. Mr. Johnson, a Chief Investment Officer of the Advisor, and Mr. Miller,
senior portfolio manager of the Fund, have managed the Fund since July 1992
and October 1996, respectively. Mr. Miller previously worked as the primary
analyst for the Fund (1996) and for Interacciones Global Inc. (1993-1995) and
McDonald & Co. Securities Inc. (1991-1993).
 
                             MICRO-CAP EQUITY FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. It invests primarily in Equity Securities of smaller
capitalization companies. The Fund attempts to provide investors with
potentially higher returns than a fund that invests primarily in larger more
established companies. Since smaller capitalization companies are generally
not as well known to investors and have less of an investor following than
larger companies, they may provide higher returns due to inefficiencies in the
marketplace.
 
  . Under normal market conditions, the Fund will invest at least 65% of its
    assets in Equity Securities of companies having a market capitalization
    of $200 million or less, which is considerably less than the market
    capitalization of S&P 500 companies.
 
  The Advisor will choose companies that:
 
  . present the ability to grow significantly over the next several years
 
  . may benefit from changes in technology, regulations and industry sector
    trends
 
  . are still in the developmental stage and may have limited product lines.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                           MULTI-SEASON GROWTH FUND
   
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term

shareholder approval. Its style, which focuses on both growth prospects and
valuation, is known as GARP (Growth at a Reasonable Price) and seeks to
produce     
 
                                      32
<PAGE>
 
   
attractive returns during various market environments. The Fund invests at
least 65% of its assets in Equity Securities. The Fund generally invests in
Equity Securities of companies with market capitalizations over $1 billion.
    
  The Advisor chooses the Fund's investments as follows: The Advisor reviews
the earnings growth of approximately 5,500 companies over the past five years.
It invests in approximately 50 to 100 companies based on:
 
  . superior earnings growth
 
  . financial stability
 
  . relative market value
 
  . price changes compared to the S&P 500.
   
  PORTFOLIO MANAGEMENT. Leonard J. Barr II is the Fund's portfolio manager, a
position he has held since the Fund's inception in April 1993. Mr. Barr is the

to April 1993 he held similar positions with MCM.     
 
                      REAL ESTATE EQUITY INVESTMENT FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide both capital
appreciation and current income. This goal is "fundamental" and cannot be
changed without shareholder approval. The Fund invests primarily in U.S.
companies which are principally engaged in the real estate industry or which
own significant real estate. A company is "principally engaged" in the real
estate industry if at least 50% of its assets, gross income or net profits are
attributable to ownership, construction, management or sale of residential,
commercial or industrial real estate. The Fund will not own real estate
directly.
 
  Under normal conditions, the Fund invests at least 65% of its total assets
in Equity Securities of U.S. companies in the real estate industry including:
 
  . equity real estate investment trusts ("REITS")
 
  . brokers, home builders and real estate developers
 
  . companies with substantial real estate holdings (for example, paper and
    lumber producers, hotels and entertainment companies)
 
  . manufacturers and distributors of building supplies
 
  . mortgage REITS
 
  . financial institutions which issue or service mortgages.
 
  In addition, the Fund may invest:
 
  . up to 35% of its assets in companies other than real estate industry
    companies
 
  . in Fixed Income Securities including up to 5% of its assets in debt
    securities rated below investment grade or unrated if secured by real
    estate assets if the Advisor believes that the underlying collateral is
    sufficient
 
  . in REITS only if they are traded on a securities exchange or NASDAQ.

                             SMALL-CAP VALUE FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation, with income as a secondary objective. It invests
primarily in Equity Securities of smaller capitalization companies. The Fund
attempts to provide investors with potentially higher returns than a fund that
invests primarily in larger more established companies. Since small companies
are generally not as well known to investors and have less of an investor
following than larger companies, they may provide higher returns due to
inefficiencies in the marketplace.
     
  . Under normal market conditions, the Fund will invest at least 65% of its
    assets in Equity Securities of companies with market capitalizations
    below $1 billion, which is less than the market capitalization of S&P 500
    companies.     
 
  The Advisor will concentrate on companies that it believes are undervalued.
A company's Equity Securities may be undervalued because the company is
temporarily overlooked or out of favor due to general economic conditions, a
market decline, industry conditions or developments affecting the particular
company. The Fund will usually invest in Equity Securities of companies with
low price/earnings ratios, low price/cash flow ratios and low price/book
values compared to the general market.
 
  In addition to valuation, the Advisor considers these factors, among others,
in choosing companies:
 
  . a stable or improving earnings record
 
  . sound finances
 
  . above-average growth prospects
 
  . participation in a fast growing industry
 
  . strategic niche position in a specialized market
 
  . adequate capitalization.

                        U.S. TREASURY MONEY MARKET FUND
 
 . The Fund's goal is to provide as high a level of current interest income as
  is consistent with maintaining liquidity and stability of principal.
 
 . The Fund invests its assets solely in short-term bonds, bills and notes
  issued by the U.S. Treasury (including "stripped" securities), and in
  repurchase agreements relating to such obligations.
 
                     WHO MAY WANT TO INVEST IN THE FUNDS?
 
 Equity Funds
 
  These Funds are designed for investors who desire potentially high capital
appreciation and who can accept short-term variations in return for
potentially greater returns over the long term. In general, the greater the
risk, the greater the potential reward. Investors who have a short time
horizon, who desire a high level of income or who are conservative in their
investment approach may wish to invest in other portfolios offered by the
Trust and the Company.
 
 Bond Funds and Tax-Free Funds
 
  These Funds are designed for investors who desire potentially higher returns
than more conservative fixed rate investments or money market funds and who
seek current income. The Tax-Free Funds may be desirable for investors who
seek primarily tax-exempt income. When you choose among the Funds, you should
consider both the expected yield of the Funds and potential changes in each
Fund's share price. The yield and potential price changes of a Fund's shares
depend on the quality and maturity of the obligations in its portfolio, as
well as on other market conditions.
 
 Money Market Funds
 
  These Funds are designed for investors who desire a high level of income and
liquidity and stability of principal.

        WHAT ARE THE FUNDS' INVESTMENTS AND INVESTMENT PRACTICES?     
 
  Each Equity Fund invests in EQUITY SECURITIES, which include common stocks,
preferred stocks, warrants and other securities convertible into common
stocks. Many of the common stocks the Funds (other than Growth & Income Fund)
will buy will not pay dividends; instead, stocks will be bought for the
potential that their prices will increase, providing capital appreciation for
the Funds. The value of Equity Securities will fluctuate due to many factors,
including the past and predicted earnings of the issuer, the quality of the
issuer's management, general market conditions, the forecasts for the issuer's
industry and the value of the issuer's assets. Holders of Equity Securities
only have rights to value in the company after all debts have been paid, and
they could lose their entire investment in a company that encounters financial
difficulty. Warrants are rights to purchase securities at a specified time at
a specified price.
   
  Each Fund may invest in CASH EQUIVALENTS, which are high-quality, short-term
money market instruments including, among other things, commercial paper,
bankers' acceptances and negotiable certificates of deposit of banks or
savings and loan associations, short-term corporate obligations and short-term
securities issued by, or guaranteed by, the U.S. Government and its agencies
or instrumentalities. These instruments will be used primarily pending
investment, to meet anticipated redemptions or as a temporary defensive
measure. If a Fund is investing defensively, it may not be pursuing its
investment objective.     
 
  All Funds may enter into REPURCHASE AGREEMENTS. Under a repurchase
agreement, a Fund agrees to purchase securities from a seller and the seller
agrees to repurchase the securities at a later time, typically within seven
days, at a set price. The seller agrees to set aside collateral at least equal
to the repurchase price. This ensures that the Fund will receive the purchase
price at the time it is due, unless the seller defaults or declares
bankruptcy, in which event the Fund will bear the risk of possible loss due to
adverse market action or delays in liquidating the underlying obligation. With
respect to the Money Market Funds, the securities held subject to a repurchase
agreement may have stated maturities exceeding 397 days provided the
repurchase agreement itself matures in 397 days.
   
  The Equity Funds may purchase ADRS, EUROPEAN DEPOSITARY RECEIPTS ("EDRS")
and GLOBAL DEPOSITARY RECEIPTS ("GDRS"). ADRs are issued by U.S. financial
institutions and EDRs and GDRs are issued by European financial institutions.
They are receipts evidencing ownership of underlying Foreign Securities.     
 
  The Funds (other than the U.S. Treasury Money Market Fund) may buy shares of
registered MONEY MARKET FUNDS. The Funds will bear a portion of the expenses
of any investment company whose shares they purchase, including operating
costs and investment advisory, distribution and administration fees. These
expenses would be in addition to a Fund's own expenses. Each Fund may invest
up to 10% of its assets in other investment companies and no more than 5% of
its assets in any one investment company.
 
  Each Fund may purchase FIXED INCOME SECURITIES. Fixed Income Securities are
securities which either pay interest at set times at either fixed or variable
rates, or which realize a discount upon maturity. Fixed Income Securities
include corporate bonds, debentures, notes and other similar corporate debt
instruments, zero coupon bonds (discount debt obligations that do not make
interest payments) and variable amount master demand notes that permit the
amount of indebtedness to vary in addition to providing for periodic
adjustments in the interest rate. Each Fund may purchase U.S. GOVERNMENT
SECURITIES, which are securities issued by, or guaranteed by, the U.S.
Government or its agencies or instrumentalities. Such securities include U.S.
Treasury bills, which have initial maturities of less than one year, U.S.
Treasury notes, which have initial maturities of one to ten years, U.S.
Treasury bonds, which generally have initial maturities of greater than ten
years, and obligations of the Federal Home Loan Mortgage Corporation, Federal
National Mortgage Association and Government National Mortgage Association.
Under normal market conditions, the Equity Funds will not invest to a
significant extent, or on a routine basis, in U.S. Government Securities.
   
  Each Fund may BORROW MONEY in an amount up to 5% of its assets for temporary
purposes and in an amount up to 33 1/3% of its assets to meet redemptions.
This is a "fundamental" policy which can be changed only by shareholders.     
 
                                      41
<PAGE>
 
   
  All of the Funds, other than the International Bond Fund, the Michigan Tax-
Free Bond Fund and the Tax-Free Intermediate Bond Fund, are classified as
"diversified funds." With respect to 75% of each diversified Fund's assets,
each diversified fund cannot invest more than 5% of its assets in a single
issuer (other than the U.S. Government and its agencies and instrumentalities).
In addition, each diversified Fund cannot invest more than 25% of its assets in
a single issuer. These restrictions do not apply to the non-diversified Funds.
    
  The Tax-Free Funds will acquire long-term instruments only if they are rated
"A" or better by Moody's Investors Service Inc. ("Moody's") or Standard &
Poor's Rating Service ("S&P") or, if unrated, are of comparable quality. These
Funds will acquire short-term instruments only if they (i) have short-term debt
ratings in the top two categories by at least one nationally recognized
statistical rating organization, (ii) are issued by an issuer with such ratings
or (iii), if unrated, are of comparable quality.
   
  The Advisor does not intend to invest more than 25% of a Fund's assets in
securities whose issuers are in the same state, except that the Advisor may
invest more than 25% of the Michigan Tax-Free Bond Fund's and the Tax- Free
Intermediate Bond Fund's assets in Michigan Municipal Obligations.     
 
  Each Tax-Free Fund may invest in short-term money market instruments on a
temporary basis or for temporary investment purposes. Short-term money market
instruments include U.S. government obligations, debt securities of issuers
having a rating within the two highest categories of either S&P or Moody's, and
certificates of deposit or bankers' acceptances of domestic branches of U.S.
banks with at least $1 billion in assets.
 
  Each Money Market Fund will invest primarily in ELIGIBLE SECURITIES (as
defined by the SEC) with remaining maturities of 397 days or less as defined by
the SEC (although securities subject to repurchase agreements, variable and
floating rate securities and certain other securities may bear longer
maturities), and the dollar-weighted average portfolio maturity of each Money
Market Fund will not exceed 90 days. Eligible Securities consist of securities
that are determined by the Advisor, under guidelines established by the Boards
of Trustees and Directors, to present minimal credit risk. Each Money Market
Fund may also hold uninvested cash pending investment of late payments for
purchase orders or during temporary defensive periods.

                 WHAT ARE THE RISKS OF INVESTING IN THE FUNDS?
 
 All Funds
 
  Consistent with a long-term investment approach, investors in a Fund should
be prepared and able to maintain their investments during periods of adverse
market conditions. By itself, no Fund is a balanced investment program and
there is no guarantee that any Fund will achieve its investment objective
since there is uncertainty in every investment.
   
  A Fund's risk is mostly dependent on the types of securities it purchases
and its investment techniques. Certain Funds are authorized to use options,
futures, and forward foreign currency exchange contracts, which are types of
derivative instruments. Derivative instruments are instruments that derive
their value from a different underlying security, index or financial
indicator. The use of derivative instruments exposes a Fund to additional
risks and transaction costs. Risks inherent in the use of derivative
instruments include: (1) the risk that interest rates, securities prices and
currency markets will not move in the direction that a portfolio manager
anticipates; (2) imperfect correlation between the price of derivative
instruments and movements in the prices of the securities, interest rates or
currencies being hedged; (3) the fact that skills needed to use these
strategies are different than those needed to select portfolio securities; (4)
the possible absence of a liquid secondary market for any particular
instrument and possible exchange imposed price fluctuation limits, either of
which may make it difficult or impossible to close out a position when
desired; (5) leverage risk, that is, the risk that adverse price movements in
an instrument can result in a loss substantially greater than the Fund's
initial investment in that instrument (in some cases, the potential loss is
unlimited); (6) particularly in the case of privately-negotiated instruments,
the risk that the counterparty will not perform its obligations, which could
leave the Fund worse off than if it had not entered into the position; and (7)
inability to close out certain hedged positions to avoid adverse tax
consequences.     
 
  To the extent that a Fund invests in illiquid securities, the Fund risks not
being able to sell securities at the time and the price that it would like.
The Fund may therefore have to lower the price, sell substitute securities or
forego an investment opportunity, each of which might adversely affect the
Fund.
 
  The risks of the various investment techniques the Funds use are described
in more detail in the SAI.
 
 Equity Funds
 
  Investing in these Funds may be less risky than investing in individual
stocks due to the diversification of investing in a portfolio of many
different stocks; however, such diversification does not eliminate all risks.
Because the Funds invest mostly in Equity Securities, rises and falls in the
stock market in general, as well as in the value of particular Equity
Securities held by the Funds, can affect the Funds' performance. Your
investment in the Funds is not guaranteed. The net asset value of the Funds
will change daily and you might not recoup the amount you invest in the Funds.
 
 Bond Funds and Tax-Free Funds
 
  The value of each Fund's shares, like the value of most securities, will
rise and fall in response to changes in economic conditions, interest rates
and the market's perception of the underlying securities held by the Fund.
Investing in these Funds may be less risky than investing in individual Fixed
Income Securities due to the diversification of investing in a portfolio
containing many different Fixed Income Securities; however, such diversity
does not eliminate all risks. The Funds invest mostly in Fixed Income
Securities, whose values typically rise when interest rates fall and fall when
interest rates rise. Fixed Income Securities with shorter maturities (time
period until repayment) tend to be less affected by interest rate changes, but
generally offer lower yields than securities with longer maturities. Current
yield levels should not be considered representative of yields for any future
time. Securities with variable interest rates may exhibit greater price
variations than ordinary securities. Zero coupon bonds are subject to greater
market fluctuations from changing interest rates than debt obligations of
comparable maturities which make current distributions of interest.
 
                                      52
<PAGE>
 
 Money Market Funds
 
  Each Money Market Fund attempts to maintain a constant net asset value of
$1.00 per share. However, your investment in these Funds is not guaranteed.
 
  Although the Cash Investment Fund and U.S. Treasury Money Market Fund expect
under normal market conditions to be as fully invested as possible, each Fund
may hold uninvested cash pending investment of late payments for purchase
orders (or other payments) or during temporary defensive periods. Uninvested
cash will not earn income. In general, investments in the Cash Investment Fund
and U.S. Treasury Money Market Fund will not earn as high a level of current
income as longer-term or lower quality securities. Longer-term and lower
quality securities, however, generally have less liquidity, greater market
risk and more fluctuation in market value.
 
  Although the Tax-Free Money Market Fund may invest more than 25% of its net
assets in municipal revenue obligations, the interest on which is paid solely
from revenues of similar projects, the Tax-Free Money Market Fund does not
intend to do so on a regular basis. If it does, the Fund will be riskier than
a fund which does not concentrate to such an extent on similar projects.
 
 Growth Opportunities Fund, Micro-Cap Equity Fund, Small-Cap Value Fund and
Small Company Growth Fund
 
  The Advisor believes that smaller companies can provide greater growth
potential and potentially higher returns than larger firms. Investing in
smaller companies, however, is riskier than investing in larger companies. The
stock of smaller companies may trade infrequently and in lower volume, making
it more difficult for a Fund to sell the stocks of smaller companies when it
chooses. Smaller companies may have limited product lines, markets, financial
resources and distribution channels, which makes them more sensitive to
changing economic conditions. Stocks of smaller companies historically have
had larger fluctuations in price than stocks of larger companies included in
the S&P 500.
 
 Framlington Emerging Markets Fund, Framlington Global Financial Services
 Fund, Framlington International Growth Fund, International Equity Fund and
 International Bond Fund
 
  Investing in any of these Funds, with their larger investment in Foreign
Securities, may involve more risk than investing in a U.S. fund for the
following reasons: (1) there may be less public information available about
foreign companies than is available about U.S. companies; (2) foreign
companies are not generally subject to the uniform accounting, auditing and
financial reporting standards and practices applicable to U.S. companies; (3)
foreign markets have less volume than U.S. markets, and the securities of some
foreign companies are less liquid and more volatile than the securities of
comparable U.S. companies; (4) there may be less government regulation of
stock exchanges, brokers, listed companies and banks in foreign countries than
in the United States; (5) the Fund may incur fees on currency exchanges when
it changes investments from one country to another; (6) the Fund's foreign
investments could be affected by expropriation, confiscatory taxation,
nationalization of bank deposits, establishment of exchange controls,
political or social instability or diplomatic developments; (7) fluctuations
in foreign exchange rates will affect the value of the Fund's portfolio
securities, the value of dividends and interest earned, gains and loses
realized on the sale of securities, net investment income and unrealized
appreciation or depreciation of investments; and (8) possible imposition of
dividend or interest withholding by a foreign country.
 
 Framlington Global Financial Services Fund
 
  Financial services companies are subject to extensive governmental
regulation which may limit both the amount and types of loans and other
financial commitments they can make, and the interest rates and fees they can
charge. Profitability is largely dependent on the availability and cost of
capital funds, and can fluctuate significantly when interest rates change.
Credit losses resulting from financial difficulties of borrowers can
negatively impact the industry. Insurance companies may be subject to severe
price competition. Legislation is currently being considered which would
reduce the separation between commercial and investment banking businesses. If
enacted, this could significantly impact the industry and the Fund. The Fund
may be riskier than a fund investing in a broader range of industries.

  Although securities of large and well-established companies in the financial
services industry will be held in the Fund's portfolio, the Fund also will
invest in medium, small and/or newly-public companies which may be subject to
greater share price fluctuations and declining growth, particularly in the
event of rapid changes in the industry and/or increased competition.
Securities of those smaller and/or less seasoned companies may, therefore,
expose shareholders of the Fund to above-average risk.
 
 Framlington Healthcare Fund
 
  The Fund will invest most of its assets in the healthcare industry, which is
particularly affected by rapidly changing technology and extensive government
regulation, including cost containment measures. The Fund may be riskier than
a fund investing in a broader range of industries.
 
 Real Estate Equity Investment Fund
 
  The Fund will invest primarily in the real estate industry and may invest
more than 25% of its assets in any one sector of the real estate industry. As
a result, the Fund will be particularly vulnerable to declines in real estate
prices and new construction rates. The Fund may be riskier than a fund
investing in a broader range of industries.
   
 International Bond Fund, Michigan Tax-Free Bond Fund and Tax-Free
Intermediate Bond Fund     
   
  These Funds are non-diversified and hold securities of a limited number of
issuers. The Funds may, therefore, pose a greater risk to investors than an
investment in a diversified fund. The Michigan Tax-Free Bond Fund invests
primarily in Michigan Municipal Obligations. If Michigan issuers suffer
serious financial difficulties jeopardizing their ability to pay their
obligations, the value of such Fund may decline.     
 
                                  PERFORMANCE
 
                   HOW IS THE FUND'S PERFORMANCE CALCULATED?
 
  There are various ways in which the Funds may calculate and report their
performance. Performance is calculated separately for each class of shares.
 
  One method is to show a Fund's total return. Cumulative total return is the
percentage change in the value of an amount invested in a class of shares of a
Fund over a stated period of time and takes into account reinvested dividends.
Cumulative total return most closely reflects the actual performance of a
Fund.
 
  Average annual total return refers to the average annual compounded rates of
return over a specified period on an investment in shares of a Fund determined
by comparing the initial amount invested to the ending redeemable value of the
amount, taking into account reinvested dividends.
 
  Each Fund may also publish its current yield. Yield is the net investment
income generated by a share of a Fund during a 30-day period divided by the
maximum offering price on the 30th day.
 
  The current yield of shares in the Money Market Funds refers to the net
income generated by an investment in shares over a seven-day period (which
period will be stated in the advertisement). This income is then "annualized."
That is, the amount of income generated by the investment during that week is
assumed to be generated each week over a 52-week period and is shown as a
percentage of the investment. "Effective yield" is calculated similarly but,
when annualized, the income earned by an investment in a class is assumed to
be reinvested. The "effective yield" will be slightly higher than the "yield"
because of the compounding effect of this assumed reinvestment. The "tax-
equivalent yield" of shares of the Tax-Free Funds and the Tax-Free Money
Market Fund which may also be quoted from time to time, shows the level of
taxable yield needed to produce an after-tax equivalent to the tax-free yield
of a particular class. This is done by increasing the yield (calculated as
above) by the amount necessary to reflect the payment of Federal and/or state
income taxes at a stated rate.
 
                                      54

  You should be aware that (i) past performance does not indicate how a Fund
will perform in the future; and (ii) each Fund's return and net asset value
will fluctuate, so you cannot necessarily use a Fund's performance data to
compare it to investment in certificates of deposit, savings accounts or other
investments that provide a fixed or guaranteed yield.
 
  Each Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. Each Fund may also compare its total return
to broad-based indices. These indices show the value of selected portfolios of
securities (assuming reinvestment of interest and dividends) which are not
managed by a portfolio manager. The Funds may report how they are performing in
comparison to the Consumer Price Index, an indication of inflation reported by
the U.S. Government.
 
                      WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Funds' annual report dated June 30 of each year and semi-
annual report dated December 31 of each year, which will automatically be
mailed to shareholders. To obtain copies of financial reports or performance
information, call (800) 438-5789.
 
                              PURCHASES OF SHARES
 
  Customers of banks and other institutions, and the immediate family members
of such Customers, that have entered into agreements with us to provide
shareholder services for Customers may purchase Class K Shares. Customers may
include individuals, trusts, partnerships and corporations. Each Fund also
issues other classes of shares, which have different sales charges, expense
levels and performance. Call (800) 438-5789 to obtain more information
concerning the Funds' other classes of shares.
 
                        WHAT PRICE DO I PAY FOR SHARES?
   
  The purchase price for Class K Shares is the net asset value ("NAV") next
determined after we receive your order in proper form. Except in certain
limited circumstances, each Fund determines its NAV on each day the New York
Stock Exchange ("NYSE") is open for trading (a "Business Day") at the close of
such trading on the NYSE (normally 4:00 p.m. Eastern time). The Money Market
Funds also determine their NAVs at 2:45 p.m. (Eastern time). If we receive your
purchase order and payment for a Money Market Fund by 2:45 p.m. (Eastern time)
on a Business Day, you will receive dividends on that day. Each Fund calculates
NAV separately for each class of shares. NAV is calculated by totaling the
value of all of the assets of a Fund allocated to a particular class of shares,
subtracting the Fund's liabilities and expenses charged to that class and
dividing the result by the number of shares of that class outstanding.     
 
                          WHEN CAN I PURCHASE SHARES?
 
  Shares of each Fund are sold on a continuous basis and can be purchased on
any Business Day.
 
                           HOW CAN I PURCHASE SHARES?
 
  All share purchases are effected through a Customer's account at an
institution and confirmations of share purchases will be sent to the
institution involved. Institutions (or their nominees) will normally be the
holders of record of Fund shares acting on behalf of their Customers, and will
reflect their Customers' beneficial ownership of shares in the account
statements provided by them to their Customers.
   
  We do not issue share certificates. We reserve the right to (i) reject any
purchase order if, in our opinion, it is in the Funds' best interest to do so
and (ii) suspend the offering of shares of any class for any period of time.
    
                                       55
<PAGE>
 
  You may pay for shares of each Fund, other than the Real Estate Equity
Investment Fund, with securities which the Fund is allowed to hold.
 
                             REDEMPTIONS OF SHARES
 
                  WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?
 
  The redemption price is the NAV next determined after we receive the
redemption request in proper form.
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. A Fund may temporarily stop redeeming
shares when the NYSE is closed or trading on the NYSE is restricted, when an
emergency exists and the Fund cannot sell its assets or accurately determine
the value of its assets or if the SEC orders the Fund to suspend redemptions.
 
                            HOW CAN I REDEEM SHARES?
 
  Redemption orders are effected at the NAV per share next determined after
receipt of the order by the Transfer Agent. Shares held by an institution on
behalf of its Customers must be redeemed in accordance with instructions and
limitations pertaining to the account at that institution.
 
  . FREE CHECKWRITING. Free checkwriting is available to holders of Class K
    Shares of the Bond Funds (other than the International Bond Fund), Tax-
    Free Funds and Money Market Funds who complete the Signature Card Section
    of the Account Application Form. You may write checks in the amount of
    $500 or more but you may not close a Fund account by writing a check. We
    may change or terminate this program on 30 days' notice to you.
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  If we receive a redemption order for a Fund before 4:00 p.m. (Eastern time)
on a Business Day, we will normally wire payment to the redeeming institution
on the next Business Day. With respect to a Money Market Fund, if we receive a
redemption order before noon (Eastern time) on a Business Day, we will normally
wire payment on the same Business Day. We may delay wiring redemption proceeds
for up to seven days if we feel an earlier payment would have a negative impact
on the Fund.
 
                     STRUCTURE AND MANAGEMENT OF THE FUNDS
 
                         HOW ARE THE FUNDS STRUCTURED?
 
  The Trust, the Company and Framlington are each an open-end management
investment company, which is a mutual fund that sells and redeems shares every
day that it is open for business. They are managed under the direction of their
governing Boards of Trustees and Directors, which are responsible for the
overall management of the Trust, the Company and Framlington and supervise the
Funds' service providers. The Trust and Framlington are organized as
Massachusetts business trusts and the Company is a Maryland corporation.
 
                      WHO MANAGES AND SERVICES THE FUNDS?
   
  INVESTMENT ADVISOR AND SUB-ADVISOR. The Funds' investment advisor is Munder
Capital Management, a Delaware general partnership with its principal offices
at 480 Pierce Street, Birmingham, Michigan 48009. The principal partners of the
Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM Holdings
II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware corporation
and was a registered investment advisor. WAM and WAM II are Delaware
corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,
1998, the Advisor and its affiliates had approximately $48.2 billion in assets
under management, of which $25.4 billion were invested in equity securities,
$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion in
non-discretionary assets.     
 
                                       56
<PAGE>
 
  The Advisor provides overall investment management and research and credit
analysis for each Fund and is responsible for all purchases and sales of
portfolio securities for each Fund other than the Framlington Funds.
 
  Framlington Overseas Investment Management Limited is the sub-advisor of the
Framlington Funds. The Sub-Advisor is an indirect subsidiary of Framlington
Holdings Limited which is, in turn, owned 49% by the Advisor and 51% by Credit
Commercial de France S.A., a French banking corporation listed on the Societe
des Bourses Francaises.
 
  The Sub-Advisor provides research and credit analysis for each of the
Framlington Funds and is responsible for all purchases and sales of portfolio
securities for each of the Framlington Funds other than the Framlington Global
Financial Services Fund. Each of the Advisor and Sub-Advisor manages a portion
of the assets of the Framlington Global Financial Services Fund. The Advisor
is responsible for all purchases and sales of domestic securities held by the
Fund. The Sub-Advisor is responsible for the allocation of the Fund's assets
among countries and for all purchases and sales of foreign securities held by
the Fund.
 
  During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate based on the average daily net assets of each Fund
(after waivers, if any) as follows:

  The Advisor is entitled to receive an annual fee equal to .20% of the first
$250 million of the Index 500 Fund's average daily net assets, .12% of the
next $250 million of the Fund's average daily net assets and .07% of the
Fund's average daily net assets over $500 million. During the past fiscal
year, the Advisor waived advisory fees for the Index 500 Fund and the Multi-
Season Growth Fund. The Advisor is also entitled to receive an annual fee
equal to 1.00% of the first $500 million of the Multi-Season Growth Fund's
average daily net assets and .75% of the Fund's average daily net assets over
$500 million.     
   
  During the fiscal year ended June 30, 1998, the Sub-Advisor received an
advisory fee equal to one-half of the fee paid to the Advisor by each of the
Framlington Funds as compensation for its services as Sub-Advisor. The Advisor
pays fees to the Sub-Advisor and the Framlington Funds pay no fees directly to
the Sub-Advisor.     
 
  The Advisor may, from time to time, make payments to banks, broker-dealers
or other financial institutions for certain services to the Funds and/or their
shareholders, including sub-administration, sub-transfer agency and
shareholder servicing. The Advisor may make such payments out of its own
resources and there are no additional costs to the Funds or their
shareholders.
   
  The Advisor or Sub-Advisor, in the case of the Framlington Funds, selects
broker-dealers to execute portfolio transactions for the Funds based on best
price and execution terms. The Advisor or Sub-Advisor may consider as a factor
the number of shares sold by the broker-dealer.     
 
  PERFORMANCE INFORMATION. The tables below contain performance information
for certain Funds created through the conversion of a common or collective
trust fund which had investment objectives and policies materially equivalent
to those of the corresponding Funds. Immediately before and after the
conversion, the same person managed both the common or collective trust fund
and the corresponding Fund.

  The table for each Fund:
 
  . includes the average annual total returns of the common or collective
    trust fund and the average annual total returns of the corresponding Fund
    linked together;
 
  . assumes that net investment income and dividends have been reinvested;
 
  . assumes that the common or collective trust fund paid the same levels of
    fees and expenses as the corresponding Fund currently pays;
 
  . does not reflect any potential negative impact on the common and
    collective trust funds' performance if they had been subjected to the
    same regulatory restrictions (the Investment Company Act of 1940, as
    amended (the "1940 Act") and the Internal Revenue Code of 1986, as
    amended) as the corresponding Fund; and
 
  . indicates past performance only and does not predict future results.

PERFORMANCE OF FRAMLINGTON ACCOUNTS MANAGED BY THE SUB-ADVISOR
 
  The tables below contain certain performance information provided by the
Sub-Advisor relating to accounts managed by the Sub-Advisor and which have
investment objectives and policies similar to those of the corresponding
Framlington Funds. See "Fund Choices" and "What are the Funds' Investments and
Investment Practices?" In the case of the Healthcare portfolio performance,
the data relates to a unit trust organized under the laws of the United
Kingdom managed by the same personnel of the Sub-Advisor with similar
investment objectives and policies to the Framlington Healthcare Fund. In the
case of Emerging Markets portfolio performance, the data relates to a
Canadian-based institutional emerging markets portfolio managed by the same
personnel of the Sub-Advisor with similar investment objectives and policies
to the Framlington Emerging Markets Fund.
   
  The trust account performance is provided by Standard & Poor's Micropal, an
independent research organization that is a recognized source of performance
data in the UK unit trust industry. The data is U.S. dollar adjusted on the
basis of exchange rates provided by Datastream using WM/Reuters closing rates.
The performance figures are net of brokerage commissions, actual investment
advisory fees and initial sales charges. The data assume the reinvestment of
net income and capital gain distributions. The trust account returns are
calculated using beginning offer and ending bid prices for periods ended
December 31, 1996.     
 
  You should not rely on the following performance data of the Sub-Advisor's
client accounts as an indication of future performance of the Framlington
Funds. It should be noted that the management of the Funds will be affected by
regulatory requirements under the 1940 Act and requirements of the Internal
Revenue Code of 1986, as amended, to qualify as a regulated investment
company.

  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Funds'
transfer agent. The Transfer Agent is a wholly-owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
01581-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Funds' administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Company, the Trust and Framlington in all aspects of their administration
and operations including overseeing the maintenance of financial records and
fund accounting. As compensation for its services for the Company, the Trust
and Framlington, State Street is entitled to receive fees, based on the
aggregate daily net assets of the Funds and certain other investment
portfolios that are advised by the Advisor for which it provides services,
computed daily and payable monthly at the annual rate of 0.113% on the first
$2.8 billion of net assets, plus 0.103% on the next $2.2 billion of net
assets, plus 0.101% on the next $2.5 billion of net assets, plus 0.095% on the
next $2.5 billion of net assets, plus 0.080% on the next $2.5 billion of net
assets, plus 0.070% on all net assets in excess of $12.5 billion (with a
$75,000 minimum fee per annum in the aggregate for all portfolios with respect
to the Administrator). If the assets of the Framlington Funds do not exceed
$120 million, the ultimate rate charged the Framlington Funds will be reduced
by their pro-rata portion of the total fees if calculated at the rates of
0.062% of the first $2.8 billion of net assets, plus 0.052% of the next $2.2
billion of net assets, plus 0.050% of all net assets in excess of $5 billion.
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Funds. State Street pays the Distributor a fee
for these services out of its own resources at no cost to the Funds.
 
  CUSTODIAN AND SUB-CUSTODIAN. Comerica Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Funds' custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Funds beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Funds. State Street serves as the Funds' sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Funds' shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Funds' shares.
   
  For an additional description of the services performed by the
Administrator, the Transfer Agent, the Custodian, the Sub-Custodian and the
Distributor, see the SAI.     
 
  The Funds have adopted a Shareholder Servicing Plan (the "Class K Plan")
under which Class K Shares are sold through institutions which enter into
shareholder servicing agreements with the Funds. The agreements require the
institutions to provide shareholder services to their Customers who from time
to time own of record or beneficially Class K Shares in return for payment by
a Fund at a rate not exceeding .25% (on an annualized basis) of the average
daily net asset value of the Class K Shares beneficially owned by the
Customers. Class K Shares bear all fees paid to institutions under the Class K
Plan. Payments under the Class K Plan are not tied exclusively to the
shareholder expenses actually incurred by the institutions and the payments
may exceed service expenses actually incurred.
 
  The services provided by institutions under the Class K Plan may include
processing purchase, exchange and redemption requests from Customers and
placing orders with the Transfer Agent; processing dividend and distribution
payments from the Funds on behalf of Customers; providing information
periodically to Customers showing their positions in Class K Shares; providing
sub-accounting with respect to Class K Shares beneficially owned by Customers
or the information necessary for sub-accounting; responding to inquires from
customers concerning their investment in Class K Shares; arranging for bank
wires; and providing such other similar services as may be reasonably
requested.

  YEAR 2000. The Funds' operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Funds. The Funds have been
informed that their major service providers have made compliance with the Year
2000 Issue a high priority and are taking steps that they believe are
reasonably designed to address the Year 2000 Issue with respect to their
computer systems. There can be, however, no assurance that these steps will be
successful, or that interaction with other non-complying computer systems will
not impair their services at that time.     
 
                      WHAT ARE MY RIGHTS AS A SHAREHOLDER?
 
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
the Trust, the Company or Framlington as a whole and affecting your particular
Fund. You will not vote by class unless expressly required by law or when the
Trustees or Directors determine the matter to be voted on affects only the
interests of the holders of a particular class of shares. The Trust, the
Company and Framlington will not hold annual shareholder meetings, but special
meetings may be held at the written request of shareholders owning more than
10% of outstanding shares for the purpose of removing a Trustee or Director.
Under Massachusetts law, it is possible that a shareholder may be personally
liable for the Trust's or Framlington's obligations. If a shareholder were
required to pay a debt of a Fund, however, the Trust and Framlington have
committed to reimburse the shareholder in full from their assets. The SAI
contains more information regarding voting rights.
 
  Comerica currently has the right to vote a majority of the outstanding shares
of the Funds as agent, custodian or trustee for its customers and therefore it
is considered to be a controlling person of the Trust, the Company and
Framlington.
 
                       DIVIDENDS, DISTRIBUTIONS AND TAXES
 
               WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUNDS?
          
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on a Fund's investments. The Funds pass their earnings along to
investors in the form of dividends. Dividend distributions are the dividends or
interest earned on investments after expenses. The Balanced Fund, Growth &
Income Fund, Small Company Growth Fund and International Bond Fund pay
dividends quarterly. The Growth Opportunities Fund, Framlington Emerging
Markets Fund, Framlington Global Financial Services Fund, Framlington
Healthcare Fund, Framlington International Growth Fund, International Equity
Fund, Micro-Cap Equity Fund, Multi-Season Growth Fund, Small-Cap Value Fund and
Value Fund pay dividends at least annually. The Bond Funds (other than the
International Bond Fund) and the Tax-Free Funds pay dividends monthly.
Dividends for the Money Market Funds are declared daily and paid monthly. Each
Fund distributes its net realized capital gains (including net short-term
capital gains), if any, at least annually.     
 
  It is possible that a Fund may make a distribution in excess of the Fund's
current and accumulated earnings and profits. You will treat such a
distribution as a return of capital which is applied against and reduces your
basis in your shares. You will treat the excess of any such distribution over
your basis in your shares as gain from a sale or exchange of the shares.
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Funds will pay dividend and capital gains distributions in additional
shares of the same class of a Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Fund at (800) 438-5789.

           ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUNDS?
   
  This section contains a brief summary of the tax implications of ownership in
the Funds' shares. A more detailed discussion about the tax treatment of
distributions from the Funds and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Funds, is contained in the SAI. You should
consult your tax advisor regarding the impact of owning the Funds' shares on
your own personal tax situation including the applicability of any state and
local taxes.     
 
  In general, as long as each Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. Each Fund intends to
qualify annually as a RIC. Even if it qualifies as a RIC, a Fund may still be
liable for any excise tax on income that is not distributed in accordance with
a calendar year requirement; the Funds intend to avoid the excise tax by making
timely distributions.
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains derived from sales of portfolio securities held by a Fund will
generally be designated as long-term or short-term. Distributions from a Fund's
long-term capital gains are generally taxed at the long-term capital gains rate
regardless of how long you have owned shares in the Fund. Dividends from other
sources are generally taxed as ordinary income.
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from each Fund in which
you are a shareholder a statement of the amount and nature of the distributions
made to you during the year.
 
  If you redeem, transfer or exchange Fund shares, you may have taxable gain or
a loss. If you hold Fund shares for six months or less, and during that time
you receive a capital gain dividend, any loss you realize on the sale of these
Fund shares will be treated as a long-term loss to the extent of the earlier
distribution.
 
  Dividends and certain interest income earned from foreign securities by a
Fund may be subject to foreign withholding or other taxes. A Fund may be
permitted to pass on to its shareholders the right to a credit or deduction for
income or other tax credits earned from foreign investments and will do so if
possible. These deductions or credits may be subject to tax law limitations.
 
  If a Fund invests in certain "passive foreign investment companies"
("PFICs"), it will be subject to Federal income tax (and possibly additional
interest charges) on a portion of any "excess distribution" or gain from the
disposition of such shares, even if it distributes such income to its
shareholders. If a Fund elects to treat a PFIC as a "qualified electing fund"
("QEF") and the PFIC furnishes certain financial information in the required
form to such Fund, the Fund will instead be required to include in income each
year its allocable share of the ordinary earnings and net capital gains of the
QEF, regardless of whether received, and such amounts will be subject to the
various distribution requirements described above. The Funds may also elect to
mitigate the tax effects of owning PFIC stock by making an annual mark-to-
market election with respect to PFIC shares.
 
                             ADDITIONAL INFORMATION
 
  SHAREHOLDER COMMUNICATIONS. You will receive unaudited Semi-Annual Reports
and audited Annual Reports on a regular basis from the Funds. In addition, you
will also receive updated Prospectuses or Supplements to this Prospectus. In
order to eliminate duplicate mailings, the Funds will only send one copy of the
above communications to (1) accounts with the same primary record owner, (2)
joint tenant accounts, (3) tenant in common accounts and (4) accounts which
have the same address.

    which exceeds the inflation rate and the return provided by money market

  . The International Bond Fund seeks to provide a competitive total return
    through a combination of current income and capital appreciation.
 
  . The U.S. Government Income Fund seeks to provide high current income.

Q: What are the Funds' strategies?
 
A: BALANCED FUND
 
  . This Fund allocates its assets primarily among three types of assets--
    Equity Securities, Fixed Income Securities and Cash Equivalents. "Equity
    Securities" include common stocks, preferred stocks, warrants and other
    securities convertible into common stock. "Fixed Income Securities" are
    securities which either pay interest at set times at either fixed or
    variable rates, or which realize a discount upon maturity. Fixed Income
    Securities include corporate bonds, debentures, notes and other similar
    corporate debt instruments, zero coupon bonds (discount debt obligations
    that do not make interest payments) and variable amount master demand
    notes that permit the amount of indebtedness to vary in addition to
    providing for periodic adjustments in the interest rates. "Cash
    Equivalents" are instruments which are highly liquid and virtually free of
    investment risk.

expenses for the Growth Opportunities Fund and the Framlington Global
Financial Services Fund are based on estimated operating expenses for the
current fiscal year; and (ii) the expenses for the Framlington Emerging

 * The Advisor expects to voluntarily waive a portion of its advisory fees for
   the current fiscal year. Without waiver, the ratio of advisory fees to
   average net assets would be .93% and total fund operating expenses would be
   at 1.14%. The Advisor may discontinue such voluntary waivers at any time in
   its sole discretion.     
 + After expense reimbursements, if any.
   
++ The Advisor expects to voluntarily reimburse the Funds for certain
   operating expenses. In the absence of such expense reimbursements, the
   total fund operating expenses would be 1.89% for the Framlington Emerging
   Markets Fund, 2.15% for the Framlington Healthcare Fund, 1.57% for the
   Framlington International Growth Fund, 1.53% for the Micro-Cap Equity Fund,
   1.61% for the NetNet Fund and .63% for the Short Term Treasury Fund; and it
   is estimated that total fund operating expenses would be 1.32% for the
   Framlington Global Financial Services Fund and 1.16% for the Growth
   Opportunities Fund. The Advisor may discontinue such voluntary expense
   reimbursements at any time in its sole discretion.

                               FUND CHOICES     
 
                            WHAT FUNDS ARE OFFERED?
 
  This Prospectus offers Class Y Shares of the Funds described below. This
section summarizes each Fund's principal investments. The sections entitled
"What are the Funds' Investments and Investment Practices?" and "What are the
Risks of Investing in the Funds?" and the SAI give more information about the
Funds' investment techniques and risks. Capitalized terms are explained in the
section entitled "What are the Funds' Investments and Investment Practices?"
       
                                 BALANCED FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide an attractive
investment return through a combination of growth of capital and current
income. The Fund will allocate its assets among three asset groups: Equity
Securities, Fixed Income Securities and Cash Equivalents.
 
  . The Fund normally will invest at least 25% of its assets in Fixed Income
    Securities and no more than 75% of its assets in Equity Securities. The
    Fund will notify shareholders at least 30 days before changing this
    policy.
 
  The Advisor will allocate the Fund's assets to the three asset groups based
on its view of the following factors, among others:
 
  . general market and economic conditions and trends
 
  . interest rates and inflation rates
 
  . fiscal and monetary developments
 
  . long-term corporate earnings growth.
 
  The Advisor will try to take advantage of changing economic conditions by
adjusting the ratio of Equity Securities to Fixed Income Securities or Cash
Equivalents. For example, if the Advisor believes that rapid economic growth
will lead to better corporate earnings in the future, then it might increase
the Fund's Equity Securities holdings and reduce its Fixed Income Securities
and Cash Equivalents holdings.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                             GROWTH & INCOME FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide capital
appreciation and current income. It primarily invests in dividend-paying
Equity Securities and is designed for investors seeking current income and
capital appreciation from the equity markets.
 
  . Under normal circumstances, the Fund will invest at least 65% of its
    assets in income-producing common stocks and convertible preferred
    stocks.
 
  . The Fund may also purchase Fixed Income Securities which are convertible
    into or exchangeable for common stock.
 
  . The Fund may invest up to 35% of its assets in Fixed Income Securities,
    including 20% of its assets in Fixed Income Securities that are rated
    below investment grade.
 
  The Advisor generally selects large, well-known companies that it believes
have favorable prospects for dividend growth and capital appreciation. The
Fund will seek to produce a current yield greater than the Standard and Poor's
500 Composite Price Index ("S&P 500").
 
 
                                      30
<PAGE>
 
  The Fund focuses on dividend-paying Equity Securities because, over time,
dividend income has accounted for a significant portion of the total return of
the S&P 500. In addition, dividends are usually a more stable and predictable
source of return than capital appreciation. The Advisor believes that stocks
which distribute a high level of current income generally have more stable
prices than those which pay below average dividends.
 
  PORTFOLIO MANAGEMENT. Otto Hinzmann, Jr. is the Fund's portfolio manager, a
position he has held since February 1995. Mr. Hinzmann has been a Vice
President and Director of Equity Management of the Advisor or Old MCM, Inc.
("MCM"), the predecessor to the Advisor, since January 1987.
 
                           GROWTH OPPORTUNITIES FUND
   
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. The Fund invests at least 65% of its assets in the
Equity Securities of companies with market capitalizations between $500
million and $10 billion. Its style, which focuses on both growth prospects and
valuation, is known as GARP (Growth at a Reasonable Price) and seeks to
produce attractive returns during various market environments.     
 
  The Advisor chooses the Fund's investments as follows: The Advisor reviews
the earnings growth of approximately 10,000 companies over the past three
years. It invests in approximately 50 to 100 companies based on:
 
  . superior earnings growth
 
  . financial stability
 
  . relative market value
 
  . price changes compared to the Standard & Poor's MidCap 400 Index.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                           INTERNATIONAL EQUITY FUND
   
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. The Fund invests primarily in Foreign Securities and
American Depositary Receipts ("ADRs"). At least once a quarter, the Advisor
creates a list of Foreign Securities and ADRs (the "Securities List") which
the Fund may purchase based on the country where the company is located, its
competitive advantages, its past financial record, its future prospects for
growth and the market for its securities. The Advisor updates the Securities
List frequently (at least quarterly), adds new securities to the Securities
List if they are eligible and sells securities not on the updated Securities
List as soon as practicable.     
   
  After the Advisor creates the Securities List, it divides the list into two
sections. The first section is designed to provide broad coverage of
international markets. The second section increases exposure to securities
that the Advisor expects will perform better than other stocks in their
industry sectors and their markets as a whole. When the Advisor believes
broader market exposure will benefit the Fund, it will allocate up to 100% of
the Fund's assets in first section securities. When the Advisor identifies
strong potential for specific securities to perform well, the Fund may invest
up to 50% of its assets in second section securities.     
 
  . Under normal market conditions, at least 65% of the Fund's assets are
    invested in Equity Securities in at least three foreign countries.
     
  . The Fund emphasizes companies with a market capitalization of at least
    $250 million.

  PORTFOLIO MANAGEMENT. Todd B. Johnson and Theodore Miller jointly manage the
Fund. Mr. Johnson, a Chief Investment Officer of the Advisor, and Mr. Miller,
senior portfolio manager of the Fund, have managed the Fund since July 1992
and October 1996, respectively. Mr. Miller previously worked as the primary
analyst for the Fund (1996) and for Interacciones Global Inc. (1993-1995) and
McDonald & Co. Securities Inc. (1991-1993).
 
                             MICRO-CAP EQUITY FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. It invests primarily in Equity Securities of smaller
capitalization companies. The Fund attempts to provide investors with
potentially higher returns than a fund that invests primarily in larger more
established companies. Since smaller capitalization companies are generally
not as well known to investors and have less of an investor following than
larger companies, they may provide higher returns due to inefficiencies in the
marketplace.
 
  . Under normal market conditions, the Fund will invest at least 65% of its
    assets in Equity Securities of companies having a market capitalization
    of $200 million or less, which is considerably less than the market
    capitalization of S&P 500 companies.
 
  The Advisor will choose companies that:
 
  . present the ability to grow significantly over the next several years
 
  . may benefit from changes in technology, regulations and industry sector
    trends
 
  . are still in the developmental stage and may have limited product lines.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                           MULTI-SEASON GROWTH FUND
   
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. This goal is "fundamental" and cannot be changed without
shareholder approval. Its style, which focuses on both growth prospects and
valuation, is known as GARP (Growth at a Reasonable Price) and seeks to
produce attractive returns during various market environments. The Fund
invests at least 65% of its assets in Equity Securities. The Fund generally
invests in Equity Securities of companies with market capitalizations of over
$1 billion.     
 
  The Advisor chooses the Fund's investments as follows: The Advisor reviews
the earnings growth of approximately 5,500 companies over the past five years.
It invests in approximately 50 to 100 companies based on:
 
  . superior earnings growth
 
  . financial stability
 
  . relative market value
 
  . price changes compared to the S&P 500.
   
  PORTFOLIO MANAGEMENT. Leonard J. Barr II is the Fund's portfolio manager, a
position he has held since the Fund's inception in April 1993. Mr. Barr is the
Senior Vice President and Director of Research of the Advisor. From April 1988
to April 1993 he held similar positions with MCM.

                                  NETNET FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation. Under normal conditions, the Fund will invest at least
65% of its assets in Equity Securities.
 
  In choosing which companies' stock the Fund should purchase, the Advisor
invests in those companies listed on a U.S. securities exchange or NASDAQ
which are engaged in the research, design, development or manufacturing, or
engaged to a significant extent in the business of distributing products,
processes or services for use with Internet or Intranet related businesses.
The Internet is a world-wide network of computers designed to permit users to
share information and transfer data quickly and easily. The World Wide Web
("WWW"), which is a means of graphically interfacing with the Internet, is a
hyper-text based publishing medium containing text, graphics, interactive
feedback mechanisms and links within WWW documents and to other WWW documents.
An Intranet is the application of WWW tools and concepts to a company's
internal documents and databases.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
 
                      REAL ESTATE EQUITY INVESTMENT FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide both capital
appreciation and current income. This goal is "fundamental" and cannot be
changed without shareholder approval. The Fund invests primarily in U.S.
companies which are principally engaged in the real estate industry or which
own significant real estate. A company is "principally engaged" in the real
estate industry if at least 50% of its assets, gross income or net profits are
attributable to ownership, construction, management or sale of residential,
commercial or industrial real estate. The Fund will not own real estate
directly.
 
  Under normal conditions, the Fund invests at least 65% of its total assets
in Equity Securities of U.S. companies in the real estate industry including:
 
  . equity real estate investment trusts ("REITS")
 
  . brokers, home builders and real estate developers
 
  . companies with substantial real estate holdings (for example, paper and
    lumber producers, hotels and entertainment companies)
 
  . manufacturers and distributors of building supplies
 
  . mortgage REITS
 
  . financial institutions which issue or service mortgages.
 
  In addition, the Fund may invest:
 
  . up to 35% of its assets in companies other than real estate industry
    companies
 
  . in Fixed Income Securities including up to 5% of its assets in debt
    securities rated below investment grade or unrated if secured by real
    estate assets if the Advisor believes that the underlying collateral is
    sufficient
 
  . in REITS only if they are traded on a securities exchange or NASDAQ.
   
  PORTFOLIO MANAGEMENT. Peter K. Hoglund and Robert E. Crosby jointly manage
the Fund. Mr. Hoglund has managed the Fund since October 1996. Mr. Hoglund
formerly was the primary analyst of the Fund (October 1994 to October 1996).
Mr. Crosby has managed the Fund since March 1998. Mr. Crosby formerly was the
primary analyst of the Fund (October 1996 to March 1998). Mr. Crosby has been
with the Advisor since 1993, and also serves as portfolio manager for

                             SMALL-CAP VALUE FUND
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide long-term
capital appreciation, with income as a secondary objective. It invests
primarily in Equity Securities of smaller capitalization companies. The Fund
attempts to provide investors with potentially higher returns than a fund that
invests primarily in larger more established companies. Since small companies
are generally not as well known to investors and have less of an investor
following than larger companies, they may provide higher returns due to
inefficiencies in the marketplace.
 
  . Under normal market conditions, the Fund will invest at least 65% of its
    assets in Equity Securities of companies with market capitalizations
    below $750 million, which is less than the market capitalization of S&P
    500 companies.
 
  The Advisor will concentrate on companies that it believes are undervalued.
A company's Equity Securities may be undervalued because the company is
temporarily overlooked or out of favor due to general economic conditions, a
market decline, industry conditions or developments affecting the particular
company. The Fund will usually invest in Equity Securities of companies with
low price/earnings ratios, low price/cash flow ratios and low price/book
values compared to the general market.
 
  In addition to valuation, the Advisor considers these factors, among others,
in choosing companies:
 
  . a stable or improving earnings record
 
  . sound finances
 
  . above-average growth prospects
 
  . participation in a fast growing industry
 
  . strategic niche position in a specialized market
 
  . adequate capitalization.
 
  PORTFOLIO MANAGEMENT. Gerald Seizert, Edward Eberle and Brian Wall jointly
manage the Fund. Mr. Seizert, a Chief Executive Officer of the Advisor, has
managed the Fund since it commenced operations. Prior to joining the Advisor
in 1995, Mr. Seizert was a Director and Managing Partner of Loomis, Sayles &
Company, L.P. Mr. Eberle, who has managed the Fund since March 1997, was
formerly the primary analyst for the Fund. Prior to joining the Advisor in
1995, he was an Executive Vice President and Portfolio Manager for Westpointe
Financial Corporation. Mr. Wall was formerly a primary analyst for the Fund.

Smith in New York (1992-1994).
 
                           SMALL COMPANY GROWTH FUND

capital appreciation. The Fund invests primarily in Equity Securities of
smaller capitalization companies. The Fund attempts to provide investors with

  . Under normal market conditions, the Fund will invest at least 65% of the
    Fund's assets in Equity Securities of companies with market
    capitalizations below $1 billion, which is less than the market
    capitalization of S&P 500 companies.

                      WHO MAY WANT TO INVEST IN THE FUNDS?
 
 Equity Funds
 
  These Funds are designed for investors who desire potentially high capital
appreciation and who can accept short-term variations in return for potentially
greater returns over the long term. In general, the greater the risk, the
greater the potential reward. Investors who have a short time horizon, who
desire a high level of income or who are conservative in their investment
approach may wish to invest in other portfolios offered by the Trust and the
Company.
 
 Bond Funds and Tax-Free Funds
 
  These Funds are designed for investors who desire potentially higher returns
than more conservative fixed rate investments or money market funds and who
seek current income. The Tax-Free Funds may be desirable for investors who seek
primarily tax-exempt income. When you choose among the Funds, you should
consider both the expected yield of the Funds and potential changes in each
Fund's share price. The yield and potential price changes of a Fund's shares
depend on the quality and maturity of the obligations in its portfolio, as well
as on other market conditions.
 
 Short Term Treasury Fund and Money Market Funds
 
  These Funds are designed for investors who desire a high level of income and
liquidity and, in the case of the Money Market Funds, stability of principal.
            
         WHAT ARE THE FUNDS' INVESTMENTS AND INVESTMENT PRACTICES?     
 
  Each Equity Fund invests in EQUITY SECURITIES, which include common stocks,
preferred stocks, warrants and other securities convertible into common stocks.
Many of the common stocks the Funds (other than Growth & Income Fund) will buy
will not pay dividends; instead, stocks will be bought for the potential that
their prices will increase, providing capital appreciation for the Funds. The
value of Equity Securities will fluctuate due to many factors, including the
past and predicted earnings of the issuer, the quality of the issuer's
management, general market conditions, the forecasts for the issuer's industry
and the value of the issuer's assets. Holders of Equity Securities only have
rights to value in the company after all debts have been paid, and they could
lose their entire investment in a company that encounters financial difficulty.
Warrants are rights to purchase securities at a specified time at a specified
price.
   
  Each Fund (other than the Short Term Treasury Fund) may invest in CASH
EQUIVALENTS, which are high-quality, short-term money market instruments
including, among other things, commercial paper, bankers' acceptances and
negotiable certificates of deposit of banks or savings and loan associations,
short-term corporate obligations and short-term securities issued by, or
guaranteed by, the U.S. Government and its agencies or instrumentalities. These
instruments will be used primarily pending investment, to meet anticipated
redemptions or as a temporary defensive measure. If a Fund is investing
defensively, it may not be pursuing its investment objective.     
 
  All Funds may enter into REPURCHASE AGREEMENTS. Under a repurchase agreement,
a Fund agrees to purchase securities from a seller and the seller agrees to
repurchase the securities at a later time, typically within seven days, at a
set price. The seller agrees to set aside collateral at least equal to the
repurchase price. This ensures that the Fund will receive the purchase price at
the time it is due, unless the seller defaults or declares bankruptcy, in which
event the Fund will bear the risk of possible loss due to adverse market action
or delays in liquidating the underlying obligation. With respect to the Money
Market Funds, the securities held subject to a repurchase agreement may have
stated maturities exceeding 397 days provided the repurchase agreement itself
matures in 397 days.
 
                                       41
<PAGE>
 
   
  The Equity Funds may purchase ADRS, EUROPEAN DEPOSITARY RECEIPTS ("EDRS")
and GLOBAL DEPOSITARY RECEIPTS ("GDRS"). ADRs are issued by U.S. financial
institutions and EDRs and GDRs are issued by European financial institutions.
They are receipts evidencing ownership of underlying Foreign Securities.     
   
  The Funds (other than the U.S. Treasury Money Market Fund and the Short Term
Treasury Fund) may buy shares of registered MONEY MARKET FUNDS. The Funds will
bear a portion of the expenses of any investment company whose shares they
purchase, including operating costs and investment advisory, distribution and
administration fees. These expenses would be in addition to a Fund's own
expenses. Each Fund may invest up to 10% of its assets in other investment
companies and no more than 5% of its assets in any one investment company.
       
  Each Fund (other than the Short Term Treasury Fund) may purchase FIXED
INCOME SECURITIES. Fixed Income Securities are securities which either pay
interest at set times at either fixed or variable rates, or which realize a
discount upon maturity. Fixed Income Securities include corporate bonds,
debentures, notes and other similar corporate debt instruments, zero coupon
bonds (discount debt obligations that do not make interest payments) and
variable amount master demand notes that permit the amount of indebtedness to
vary in addition to providing for periodic adjustments in the interest rate.
Each Fund may purchase U.S. GOVERNMENT SECURITIES, which are securities issued
by, or guaranteed by, the U.S. Government or its agencies or
instrumentalities. Such securities include U.S. Treasury bills, which have
initial maturities of less than one year, U.S. Treasury notes, which have
initial maturities of one to ten years, U.S. Treasury bonds, which generally
have initial maturities of greater than ten years, and obligations of the
Federal Home Loan Mortgage Corporation, Federal National Mortgage Association
and Government National Mortgage Association. Under normal market conditions,
the Equity Funds will not invest to a significant extent, or on a routine
basis, in U.S. Government Securities.     
   
  Each Fund may BORROW MONEY in an amount up to 5% of its assets for temporary
purposes and in an amount up to 33 1/3% of its assets to meet redemptions.
This is a "fundamental" policy which can be changed only by shareholders.     
   
  All of the Funds, other than the International Bond Fund, the Michigan Tax-
Free Bond Fund and the Tax-Free Intermediate Bond Fund, are classified as
"diversified funds." With respect to 75% of each diversified Fund's assets,
each diversified fund cannot invest more than 5% of its assets in one issuer
(other than the U.S. Government and its agencies and instrumentalities). In
addition, each diversified fund cannot invest more than 25% of its assets in a
single issuer. These restrictions do not apply to the non-diversified funds.
    
  The Tax-Free Funds will acquire long-term instruments only if they are rated
"A" or better by Moody's Investors Service Inc. ("Moody's") or Standard &
Poor's Rating Service ("S&P") or, if unrated, are of comparable quality. These
Funds will acquire short-term instruments only if they (i) have short-term
debt ratings in the top two categories by at least one nationally recognized
statistical rating organization, (ii) are issued by an issuer with such
ratings or (iii), if unrated, are of comparable quality.
   
  The Advisor does not intend to invest more than 25% of a Fund's assets in
securities whose issuers are in the same state, except that the Advisor may
invest more than 25% of the Michigan Tax-Free Bond Fund's and the Tax- Free
Intermediate Bond Fund's assets in Michigan Municipal Obligations.     
 
  Each Tax-Free Fund may invest in short-term money market instruments on a
temporary basis or for temporary investment purposes. Short-term money market
instruments include U.S. government obligations, debt securities of issuers
having a rating within the two highest categories of either S&P or Moody's,
and certificates of deposit or bankers' acceptances of domestic branches of
U.S. banks with at least $1 billion in assets.
 
  Each Money Market Fund will invest primarily in ELIGIBLE SECURITIES (as
defined by the SEC) with remaining maturities of 397 days or less as defined
by the SEC (although securities subject to repurchase agreements, variable and
floating rate securities and certain other securities may bear longer
maturities), and the dollar-weighted average portfolio maturity of each Money
Market Fund will not exceed 90 days. Eligible Securities
 
                                      42
<PAGE>
 
consist of securities that are determined by the Advisor, under guidelines
established by the Boards of Trustees and Directors, to present minimal credit
risk. Each Money Market Fund may also hold uninvested cash pending investment
of late payments for purchase orders or during temporary defensive periods.

                 WHAT ARE THE RISKS OF INVESTING IN THE FUNDS?
 
 All Funds
 
  Consistent with a long-term investment approach, investors in a Fund should
be prepared and able to maintain their investments during periods of adverse
market conditions. By itself, no Fund is a balanced investment program and
there is no guarantee that any Fund will achieve its investment objective
since there is uncertainty in every investment.
   
  A Fund's risk is mostly dependent on the types of securities it purchases
and its investment techniques. Certain Funds are authorized to use options,
futures, and forward foreign currency exchange contracts, which are types of
derivative instruments. Derivative instruments are instruments that derive
their value from a different underlying security, index or financial
indicator. The use of derivative instruments exposes a Fund to additional
risks and transaction costs. Risks inherent in the use of derivative
instruments include: (1) the risk that interest rates, securities prices and
currency markets will not move in the direction that a portfolio manager
anticipates; (2) imperfect correlation between the price of derivative
instruments and movements in the prices of the securities, interest rates or
currencies being hedged; (3) the fact that skills needed to use these
strategies are different than those needed to select portfolio securities; (4)
the possible absence of a liquid secondary market for any particular
instrument and possible exchange imposed price fluctuation limits, either of
which may make it difficult or impossible to close out a position when
desired; (5) leverage risk, that is, the risk that adverse price movements in
an instrument can result in a loss substantially greater than the Fund's
initial investment in that instrument (in some cases, the potential loss is
unlimited); (6) particularly in the case of privately-negotiated instruments,
the risk that the counterparty will not perform its obligations, which could
leave the Fund worse off than if it had not entered into the position; and (7)
inability to close out certain hedged positions to avoid adverse tax
consequences.     
 
  To the extent that a Fund invests in illiquid securities, the Fund risks not
being able to sell securities at the time and the price that it would like.
The Fund may therefore have to lower the price, sell substitute securities or
forego an investment opportunity, each of which might adversely affect the
Fund.
 
  The risks of the various investment techniques the Funds use are described
in more detail in the SAI.
 
 Equity Funds
 
  Investing in these Funds may be less risky than investing in individual
stocks due to the diversification of investing in a portfolio of many
different stocks; however, such diversification does not eliminate all risks.
Because the Funds invest mostly in Equity Securities, rises and falls in the
stock market in general, as well as in the value of particular Equity
Securities held by the Funds, can affect the Funds' performance. Your
investment in the Funds is not guaranteed. The net asset value of the Funds
will change daily and you might not recoup the amount you invest in the Funds.
 
 Bond Funds, Tax-Free Funds and Short Term Treasury Fund
 
  The value of each Fund's shares, like the value of most securities, will
rise and fall in response to changes in economic conditions, interest rates
and the market's perception of the underlying securities held by the Fund.
Investing in these Funds may be less risky than investing in individual Fixed
Income Securities due to the diversification of investing in a portfolio
containing many different Fixed Income Securities; however, such diversity
does not eliminate all risks. The Funds invest mostly in Fixed Income
Securities, whose values typically rise when interest rates fall and fall when
interest rates rise. Fixed Income Securities with shorter maturities (time
period until repayment) tend to be less affected by interest rate changes, but
generally offer lower yields than securities with longer maturities. Current
yield levels should not be considered representative of yields for any future
time. Securities with variable interest rates may exhibit greater price
variations than ordinary securities. Zero coupon bonds are subject to greater
market fluctuations from changing interest rates than debt obligations of
comparable maturities which make current distributions of interest.
 
                                      52
<PAGE>
 
 Money Market Funds
 
  Each Money Market Fund attempts to maintain a constant net asset value of
$1.00 per share. However, your investment in these Funds is not guaranteed.
 
  Although the Cash Investment Fund, Money Market Fund and U.S. Treasury Money
Market Fund expect under normal market conditions to be as fully invested as
possible, each Fund may hold uninvested cash pending investment of late
payments for purchase orders (or other payments) or during temporary defensive
periods. Uninvested cash will not earn income. In general, investments in the
Cash Investment Fund, Money Market Fund and U.S. Treasury Money Market Fund
will not earn as high a level of current income as longer-term or lower
quality securities. Longer-term and lower quality securities, however,
generally have less liquidity, greater market risk and more fluctuation in
market value.
 
  Although the Tax-Free Money Market Fund may invest more than 25% of its net
assets in municipal revenue obligations, the interest on which is paid solely
from revenues of similar projects, the Tax-Fee Money Market Fund does not
intend to do so on a regular basis. If it does, the Fund will be riskier than
a fund which does not concentrate to such an extent on similar projects.
    
 Growth Opportunities Fund, Micro-Cap Equity Fund, NetNet Fund, Small-Cap
 Value Fund and Small Company Growth Fund     
 
  The Advisor believes that smaller companies can provide greater growth
potential and potentially higher returns than larger firms. Investing in
smaller companies, however, is riskier than investing in larger companies. The
stock of smaller companies may trade infrequently and in lower volume, making
it more difficult for a Fund to sell the stocks of smaller companies when it
chooses. Smaller companies may have limited product lines, markets, financial
resources and distribution channels, which makes them more sensitive to
changing economic conditions. Stocks of smaller companies historically have
had larger fluctuations in price than stocks of larger companies included in
the S&P 500.
 
 Framlington Emerging Markets Fund, Framlington Global Financial Services
 Fund, Framlington International Growth Fund, International Equity Fund and
 International Bond Fund
 
  Investing in any of these Funds, with their larger investment in Foreign
Securities, may involve more risk than investing in a U.S. fund for the
following reasons: (1) there may be less public information available about
foreign companies than is available about U.S. companies; (2) foreign
companies are not generally subject to the uniform accounting, auditing and
financial reporting standards and practices applicable to U.S. companies; (3)
foreign markets have less volume than U.S. markets, and the securities of some
foreign companies are less liquid and more volatile than the securities of
comparable U.S. companies; (4) there may be less government regulation of
stock exchanges, brokers, listed companies and banks in foreign countries than
in the United States; (5) the Fund may incur fees on currency exchanges when
it changes investments from one country to another; (6) the Fund's foreign
investments could be affected by expropriation, confiscatory taxation,
nationalization of bank deposits, establishment of exchange controls,
political or social instability or diplomatic developments; (7) fluctuations
in foreign exchange rates will affect the value of the Fund's portfolio
securities, the value of dividends and interest earned, gains and loses
realized on the sale of securities, net investment income and unrealized
appreciation or depreciation of investments; and (8) possible imposition of
dividend or interest withholding by a foreign country.
 
 Framlington Global Financial Services Fund
 
  Financial services companies are subject to extensive governmental
regulation which may limit both the amount and types of loans and other
financial commitments they can make, and the interest rates and fees they can
charge. Profitability is largely dependent on the availability and cost of
capital funds, and can fluctuate significantly when interest rates change.
Credit losses resulting from financial difficulties of borrowers can
 
                                      53
<PAGE>
 
negatively impact the industry. Insurance companies may be subject to severe
price competition. Legislation is currently being considered which would
reduce the separation between commercial and investment banking businesses. If
enacted, this could significantly impact the industry and the Fund. The Fund
may be riskier than a fund investing in a broader range of industries.
 
  Although securities of large and well-established companies in the financial
services industry will be held in the Fund's portfolio, the Fund also will
invest in medium, small and/or newly-public companies which may be subject to
greater share price fluctuations and declining growth, particularly in the
event of rapid changes in the industry and/or increased competition.
Securities of those smaller and/or less seasoned companies may, therefore,
expose shareholders of the Fund to above-average risk.
 
 Framlington Healthcare Fund
 
  The Fund will invest most of its assets in the healthcare industry, which is
particularly affected by rapidly changing technology and extensive government
regulation, including cost containment measures. The Fund may be riskier than
a fund investing in a broader range of industries.
 
 NetNet Fund
 
  The Fund will invest primarily in companies engaged in Internet and Intranet
related activities. The value of such companies is particularly vulnerable to
rapidly changing technology, extensive government regulation and relatively
high risks of obsolescence caused by scientific and technological advances.
The value of the Fund's shares may fluctuate more than shares of a fund
investing in a broader range of industries.
 
 Real Estate Equity Investment Fund
 
  The Fund will invest primarily in the real estate industry and may invest
more than 25% of its assets in any one sector of the real estate industry. As
a result, the Fund will be particularly vulnerable to declines in real estate
prices and new construction rates. The Fund may be riskier than a fund
investing in a broader range of industries.
   
 International Bond Fund, Michigan Tax-Free Bond Fund and Tax-Free
Intermediate Bond Fund     
   
  These Funds are non-diversified and hold securities of a limited number of
issuers. The Funds may, therefore, pose a greater risk to investors than an
investment in a diversified fund. The Michigan Tax-Free Bond Fund invests
primarily in Michigan Municipal Obligations. If Michigan issuers suffer
serious financial difficulties jeopardizing their ability to pay their
obligations, the value of such Fund may decline.     
 
                                  PERFORMANCE
 
                   HOW IS THE FUND'S PERFORMANCE CALCULATED?
 
  There are various ways in which the Funds may calculate and report their
performance. Performance is calculated separately for each class of shares.
 
  One method is to show a Fund's total return. Cumulative total return is the
percentage change in the value of an amount invested in a class of shares of a
Fund over a stated period of time and takes into account reinvested dividends.
Cumulative total return most closely reflects the actual performance of a
Fund.
 
  Average annual total return refers to the average annual compounded rates of
return over a specified period on an investment in shares of a Fund determined
by comparing the initial amount invested to the ending redeemable value of the
amount, taking into account reinvested dividends.
 
 
                                      54
<PAGE>
 
  Each Fund may also publish its current yield. Yield is the net investment
income generated by a share of a Fund during a 30-day period divided by the
maximum offering price on the 30th day.
 
  The current yield of shares in the Money Market Funds refers to the net
income generated by an investment in shares over a seven-day period (which
period will be stated in the advertisement). This income is then "annualized."
That is, the amount of income generated by the investment during that week is
assumed to be generated each week over a 52-week period and is shown as a
percentage of the investment. "Effective yield" is calculated similarly but,
when annualized, the income earned by an investment in a class is assumed to
be reinvested. The "effective yield" will be slightly higher than the "yield"
because of the compounding effect of this assumed reinvestment. The "tax-
equivalent yield" of shares of the Tax-Free Funds and the Tax-Free Money
Market Fund which may also be quoted from time to time, shows the level of
taxable yield needed to produce an after-tax equivalent to the tax-free yield
of a particular class. This is done by increasing the yield (calculated as
above) by the amount necessary to reflect the payment of Federal and/or state
income taxes at a stated rate.
 
  You should be aware that (i) past performance does not indicate how a Fund
will perform in the future; and (ii) each Fund's return and net asset value
will fluctuate, so you cannot necessarily use a Fund's performance data to
compare it to investment in certificates of deposit, savings accounts or other
investments that provide a fixed or guaranteed yield.
 
  Each Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. Each Fund may also compare its total return
to broad-based indices. These indices show the value of selected portfolios of
securities (assuming reinvestment of interest and dividends) which are not
managed by a portfolio manager. The Funds may report how they are performing
in comparison to the Consumer Price Index, an indication of inflation reported
by the U.S. Government.
 
                     WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Funds' annual report dated June 30 of each year and semi-
annual report dated December 31 of each year, which will automatically be
mailed to shareholders. To obtain copies of financial reports or performance
information, call (800) 438-5789.
 
                       PURCHASES AND EXCHANGES OF SHARES
 
  The following persons may purchase Class Y Shares:
     
  . fiduciary and discretionary accounts of institutions;     
     
  . institutional investors (including banks, savings institutions, credit
    unions and other financial institutions, pension, profit sharing and
    employee benefit plans and trusts, insurance companies, investment
    companies, investment advisors and broker-dealers acting either for their
    own accounts or for the accounts of institutional investors);     
     
  . directors, trustees, officers and employees of the Trust, the Company,
    Framlington, the Advisor and the Distributor;     
     
  . the Advisor's investment advisory clients; and     
     
  . family members of employees of the Advisor.     
 
  Each Fund also issues other classes of shares, which have different sales
charges, expense levels and performance. Call (800) 438-5789 to obtain more
information concerning the Funds' other classes of shares.
 
 
                                      55
<PAGE>
 
                        WHAT PRICE DO I PAY FOR SHARES?
 
  The purchase price for Class Y Shares is the net asset value ("NAV") next
determined after we receive your order in proper form. You should be aware
that broker-dealers (other than the Funds' Distributor) may charge investors
additional fees if shares are purchased through them.
   
  Except in certain limited circumstances, each Fund determines its NAV on
each day the New York Stock Exchange ("NYSE") is open for trading (a "Business
Day") at the close of such trading on the NYSE (normally 4:00 p.m. Eastern
time). The Money Market Funds also determine their NAVs at 2:45 p.m. (Eastern
time). If we receive your purchase order and payment for a Money Market Fund
by 2:45 p.m. (Eastern time) on a Business Day, you will receive dividends on
that day. Each Fund calculates NAV separately for each class of shares. NAV is
calculated by totaling the value of all of the assets of a Fund allocated to a
particular class of shares, subtracting the Fund's liabilities and expenses
charged to that class and dividing the result by the number of shares of that
class outstanding.     
 
                          WHEN CAN I PURCHASE SHARES?
 
  Shares of each Fund are sold on a continuous basis and can be purchased on
any Business Day.
 
                   WHAT IS THE MINIMUM REQUIRED INVESTMENT?
 
  The minimum initial investment by fiduciary and discretionary accounts of
institutions and institutional investors for Class Y Shares of the Real Estate
Equity Investment Fund is $250,000 and $500,000 for Class Y Shares of all
other Funds. Other types of investors are not subject to any minimum required
investment.
 
                          HOW CAN I PURCHASE SHARES?
 
  You can purchase Class Y Shares in a number of different ways. You may place
orders for Class Y Shares directly through the Transfer Agent or the
Distributor or through arrangements with a financial institution.
 
  . THROUGH A FINANCIAL INSTITUTION. You may purchase shares through a
    financial institution through procedures established with that
    institution. Confirmations of share purchases will be sent to the
    institution.
 
  . BY MAIL. You may open an account by completing, signing and mailing an
    Account Application Form and a check or other negotiable bank draft
    (payable to The Munder Funds) to: THE MUNDER FUNDS, C/O FIRST DATA
    INVESTOR SERVICES GROUP, P.O. BOX 5130, WESTBOROUGH, MASSACHUSETTS 01581-
    5130. You can obtain an Account Application Form by calling (800) 438-
    5789. For additional investments, send a letter stating the Fund and
    share class you wish to purchase, your name and your account number with
    a check to the address listed above.
 
  . BY WIRE. You may make additional investments in the Funds by wire. Wire
    instructions must state the Fund name, share class, your registered name
    and your account number. Your bank wire should be sent through the
    Federal Reserve Bank Wire System to:
 
                            Boston Safe Deposit and Trust Company
                            Boston, MA
                            ABA# 011001234

                            Account No.:
 
   Note that banks may charge fees for transmitting wires.
 
  . AUTOMATIC INVESTMENT PLAN ("AIP"). Under the AIP you may arrange for
    periodic investments in a Fund through automatic deductions from a
    checking or savings account. To enroll in the AIP you should complete the
    AIP Application Form or call the Funds at (800) 438-5789. The minimum
    pre-authorized investment amount is $50. You may discontinue the AIP at
    any time. We may discontinue the AIP on 30 days' written notice to you.
 
                                      56

  The Transfer Agent will send you confirmations of the opening of an account
and of all subsequent purchases, exchanges or redemptions in the account. If
your account has been set up by a broker or other investment professional,
account activity will be detailed in their statements to you.
   
  We do not issue share certificates. We reserve the right to (i) reject any
purchase order if, in our opinion, it is in the Funds' best interest to do so
and (ii) suspend the offering of shares of any class for any period of time.
You may pay for shares of each Fund, other than the Real Estate Equity
Investment Fund, with securities which the Fund is allowed to hold.     
 
  See the SAI for further information regarding purchases of the Funds'
shares.
 
                          HOW CAN I EXCHANGE SHARES?
 
  You may exchange Class Y Shares of the Funds for Class Y Shares of other
funds of the Trust, the Company or Framlington based on their relative net
asset values.
 
  You must meet the minimum purchase requirements for the fund of the Trust,
the Company or Framlington that you purchase by exchange. Please note that a
share exchange may be a taxable event and accordingly, you may realize a
taxable gain or loss. Before making an exchange request, read the Prospectus
of the fund you wish to purchase by exchange. You can obtain a Prospectus for
any fund of the Trust, the Company or Framlington by contacting your broker or
the Funds at (800) 438-5789. Brokers may charge a fee for handling exchanges.
 
  We may modify or terminate the exchange privilege at any time. You will be
given notice of any material modifications except where notice is not
required.
 
                             REDEMPTIONS OF SHARES
 
                 WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?
 
  The redemption price is the NAV next determined after we receive the
redemption request in proper form.
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. A Fund may temporarily stop
redeeming shares when the NYSE is closed or trading on the NYSE is restricted,
when an emergency exists and the Fund cannot sell its assets or accurately
determine the value of its assets or if the SEC orders the Fund to suspend
redemptions.
 
                           HOW CAN I REDEEM SHARES?
   
  Redemption orders are effected at the NAV next determined after receipt of
the order by the Transfer Agent. Shares held by an institution on behalf of
its Customers must be redeemed in accordance with instructions and limitations
pertaining to the account at that institution.     
 
  . INVOLUNTARY REDEMPTION. We may redeem your account if its value falls
    below $250 as a result of redemptions (but not as a result of a decline
    in NAV). You will be notified in writing and allowed 60 days to increase
    the value of your account to the minimum investment level.
 
  . FREE CHECKWRITING. Free checkwriting is available to holders of Class Y
    Shares of the Bond Funds (other than the International Bond Fund), Tax-
    Free Funds and Money Market Funds who complete the Signature Card Section
    of the Account Application Form. You may write checks in the amount of
    $500 or
 
                                      57

   more but you may not close a Fund account by writing a check. We may
   change or terminate this program on 30 days' notice to you.
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  If we receive a redemption order for a Fund before 4:00 p.m. (Eastern time)
on a Business Day, we will normally wire payment to the redeeming institution
on the next Business Day. With respect to a Money Market Fund, if we receive a
redemption order before noon (Eastern time) on a Business Day, we will
normally wire payment on the same Business Day. We may delay wiring redemption
proceeds for up to seven days if we feel an earlier payment would have a
negative impact on the Fund.
 
                     STRUCTURE AND MANAGEMENT OF THE FUNDS
 
                         HOW ARE THE FUNDS STRUCTURED?
 
  The Trust, the Company and Framlington are each an open-end management
investment company, which is a mutual fund that sells and redeems shares every
day that it is open for business. They are managed under the direction of
their governing Boards of Trustees and Directors, which are responsible for
the overall management of the Trust, the Company and Framlington and supervise
the Funds' service providers. The Trust and Framlington are organized as
Massachusetts business trusts and the Company is a Maryland corporation.
 
                      WHO MANAGES AND SERVICES THE FUNDS?
   
  INVESTMENT ADVISOR AND SUB-ADVISOR. The Funds' investment advisor is Munder
Capital Management, a Delaware general partnership with its principal offices
at 480 Pierce Street, Birmingham, Michigan 48009. The principal partners of
the Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM
Holdings II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware
corporation and was a registered investment advisor. WAM and WAM II are
Delaware corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,

$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion
in non-discretionary assets.     
 
  The Advisor provides overall investment management and research and credit
analysis for each Fund and is responsible for all purchases and sales of
portfolio securities for each Fund other than the Framlington Funds.
 
  Framlington Overseas Investment Management Limited is the sub-advisor of the
Framlington Funds. The Sub-Advisor is an indirect subsidiary of Framlington
Holdings Limited which is, in turn, owned 49% by the Advisor and 51% by Credit
Commercial de France S.A., a French banking corporation listed on the Societe
des Bourses Francaises.
 
  The Sub-Advisor provides research and credit analysis for each of the
Framlington Funds and is responsible for all purchases and sales of portfolio
securities for each of the Framlington Funds other than the Framlington Global
Financial Services Fund. Each of the Advisor and Sub-Advisor manages a portion
of the assets of the Framlington Global Financial Services Fund. The Advisor

Fund. The Sub-Advisor is responsible for the allocation of the Fund's assets
among countries and for all purchases and sales of foreign securities held by

  During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate based on the average daily net assets of each Fund
(after waivers, if any) as follows:

  The Advisor is also entitled to receive an annual fee equal to 1.00% of the
first $500 million of the Multi-Season Growth Fund's average daily net assets
and .75% of the Fund's average daily net assets over $500 million. During the
past fiscal year, the Advisor waived advisory fees for the Multi-Season Growth
Fund.     
   
  During the fiscal year ended June 30, 1998, the Sub-Advisor received an
advisory fee equal to one-half of the fee paid to the Advisor by each of the
Framlington Funds as compensation for its services as Sub-Advisor. The Advisor
pays fees to the Sub-Advisor and the Framlington Funds pay no fees directly to
the Sub-Advisor.     
 
  The Advisor may, from time to time, make payments to banks, broker-dealers
or other financial institutions for certain services to the Funds and/or their
shareholders, including sub-administration, sub-transfer agency and
shareholder servicing. The Advisor may make such payments out of its own
resources and there are no additional costs to the Funds or their
shareholders.
   
  The Advisor or Sub-Advisor, in the case of the Framlington Funds, elects
broker-dealers to execute portfolio transactions for the Funds based on best
price and execution terms. The Advisor or Sub-Advisor may consider as a factor
the number of shares sold by the broker-dealer.     
 
  PERFORMANCE INFORMATION. The tables below contain performance information
for certain Funds created through the conversion of a common or collective
trust fund which had investment objectives and policies materially equivalent
to those of the corresponding Funds. Immediately before and after the
conversion, the same person managed both the common or collective trust fund
and the corresponding Fund.
 
  The table for each Fund:
 
  . includes the average annual total returns of the common or collective
    trust fund and the average annual total returns of the corresponding Fund
    linked together;
 
  . assumes that net investment income and dividends have been reinvested;
 
  . assumes that the common or collective trust fund paid the same levels of
    fees and expenses as the corresponding Fund currently pays;
 
  . does not reflect any potential negative impact on the common and
    collective trust funds' performance if they had been subjected to the
    same regulatory restrictions (the Investment Company Act of 1940, as
    amended (the "1940 Act") and the Internal Revenue Code of 1986, as
    amended) as the corresponding Fund; and
 
  . indicates past performance only and does not predict future results.

PERFORMANCE OF FRAMLINGTON ACCOUNTS MANAGED BY THE SUB-ADVISOR
 
  The tables below contain certain performance information provided by the
Sub-Advisor relating to accounts managed by the Sub-Advisor and which have
investment objectives and policies similar to those of the corresponding
Framlington Funds. See "Fund Choices" and "What are the Funds' Investments and
Investment Practices?" In the case of the Healthcare portfolio performance,
the data relates to a unit trust organized under
 
                                      61
<PAGE>
 
the laws of the United Kingdom managed by the same personnel of the Sub-
Advisor with similar investment objectives and policies to the Framlington
Healthcare Fund. In the case of Emerging Markets portfolio performance, the
data relates to a Canadian-based institutional emerging markets portfolio
managed by the same personnel of the Sub-Advisor with similar investment
objectives and policies to the Framlington Emerging Markets Fund.
   
  The trust account performance is provided by Standard & Poor's Micropal, an
independent research organization that is a recognized source of performance
data in the UK unit trust industry. The data is U.S. dollar adjusted on the
basis of exchange rates provided by Datastream using WM/Reuters closing rates.
The performance figures are net of brokerage commissions, actual investment
advisory fees and initial sales charges. The data assume the reinvestment of
net income and capital gain distributions. The trust account returns are
calculated using beginning offer and ending bid prices for periods ended
December 31, 1996.     
 
  You should not rely on the following performance data of the Sub-Advisor's
client accounts as an indication of future performance of the Framlington
Funds. It should be noted that the management of the Funds will be affected by
regulatory requirements under the 1940 Act and requirements of the Internal
Revenue Code of 1986, as amended, to qualify as a regulated investment
company.

  The MSCI Emerging Markets Free Index is maintained by Morgan Stanley Capital
International, and covers 26 countries and represents the investment
opportunities in emerging markets available to foreign investors. Total return
is calculated using the prices of the companies tracked and assumes the
reinvestment of dividends.
   
  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Funds'
transfer agent. The Transfer Agent is a wholly-owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
01581-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Funds' administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Company, the Trust and Framlington in all aspects of their administration
and operations including overseeing the maintenance of financial records and
fund accounting. As compensation for its services for the Company, the Trust
and Framlington, State Street is entitled to receive fees, based on the
aggregate daily net assets of the Funds and certain other investment
portfolios that are advised by the Advisor for which it provides services,
computed daily and payable monthly at the annual rate of 0.113% on the first
$2.8 billion of net assets, plus 0.103% on the next $2.2 billion of net
assets, plus 0.101% on the next $2.5 billion of net assets, plus 0.095% on the
next $2.5 billion of net assets, plus 0.080% on the next $2.5 billion of net
assets, plus 0.070% on all net assets in excess of $12.5 billion (with a
$75,000 minimum fee per annum in the aggregate for all portfolios with respect
to the Administrator). If the assets of the Framlington Funds do not exceed
$120 million, the ultimate rate charged the Framlington Funds will be reduced
by their pro-rata portion of the total fees if calculated at the rates of
0.062% of the first $2.8 billion of net assets, plus 0.052% of the next $2.2
billion of net assets, plus 0.050% of all net assets in excess of $5 billion.
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Funds. State Street pays the Distributor a fee
for these services out of its own resources at no cost to the Funds.
 
  CUSTODIAN AND SUB-CUSTODIAN. Comerica Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Funds' custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Funds beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Funds. State Street serves as the Funds' sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Funds' shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Funds' shares.
 
  For an additional description of the services performed by the
Administrator, the Transfer Agent, the Custodian, the Sub-Custodian and the
Distributor, see the SAI.
   
  YEAR 2000. The Funds' operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Funds. The Funds have been
informed that their major service providers have made compliance with the Year
2000 Issue a high priority and are taking steps that they believe are
reasonably designed to address the Year 2000 Issue with respect to their
computer systems. There can be, however, no assurance that these steps will be
successful, or that interaction with other non-complying computer systems will
not impair their services at that time.     
 
                     WHAT ARE MY RIGHTS AS A SHAREHOLDER?
 
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
 
                                      63
<PAGE>
 
the Trust, the Company or Framlington as a whole and affecting your particular
Fund. You will not vote by class unless expressly required by law or when the
Trustees or Directors determine the matter to be voted on affects only the
interests of the holders of a particular class of shares. The Trust, the
Company and Framlington will not hold annual shareholder meetings, but special
meetings may be held at the written request of shareholders owning more than
10% of outstanding shares for the purpose of removing a Trustee or Director.
Under Massachusetts law, it is possible that a shareholder may be personally
liable for the Trust's or Framlington's obligations. If a shareholder were
required to pay a debt of a Fund, however, the Trust and Framlington have
committed to reimburse the shareholder in full from their assets. The SAI
contains more information regarding voting rights.
 
  Comerica currently has the right to vote a majority of the outstanding
shares of the Funds as agent, custodian or trustee for its customers and
therefore it is considered to be a controlling person of the Trust, the
Company and Framlington.
 
                      DIVIDENDS, DISTRIBUTIONS AND TAXES
 
               WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUNDS?
   
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on a Fund's investments. The Funds pass their earnings along to
investors in the form of dividends. Dividend distributions are the dividends
or interest earned on investments after expenses. The Balanced Fund, Growth &
Income Fund, Small Company Growth Fund and International Bond Fund pay
dividends quarterly. The Framlington Emerging Markets Fund, Framlington Global
Financial Services Fund, Framlington Healthcare Fund, Framlington
International Growth Fund, Growth Opportunities Fund, International Equity
Fund, Micro-Cap Equity Fund, Multi-Season Growth Fund, NetNet Fund, Small-Cap
Value Fund and Value Fund pay dividends at least annually. The Bond Funds
(other than the International Bond Fund) pay dividends monthly. Dividends for
the Cash Investment Fund, Money Market Fund, U.S. Treasury Money Market Fund
and Tax-Free Money Market Fund are declared daily and paid monthly.     
 
  Each Fund distributes its net realized capital gains (including net short-
term capital gains), if any, at least annually.
 
  It is possible that a Fund may make a distribution in excess of the Fund's
current and accumulated earnings and profits. You will treat such a
distribution as a return of capital which is applied against and reduces your
basis in your shares. You will treat the excess of any such distribution over
your basis in your shares as gain from a sale or exchange of the shares.
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Funds will pay dividend and capital gains distributions in additional
shares of the same class of a Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Fund at (800) 438-5789.
 
          ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUNDS?
   
  This section contains a brief summary of the tax implications of ownership
in the Funds' shares. A more detailed discussion about the tax treatment of
distributions from the Funds and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Funds, is contained in the SAI. You should
consult your tax advisor regarding the impact of owning the Funds' shares on
your own personal tax situation including the applicability of any state and
local taxes.     
 
  In general, as long as each Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. Each Fund intends to
qualify annually as a RIC. Even if it
 
                                      64
<PAGE>
 
qualifies as a RIC, a Fund may still be liable for any excise tax on income
that is not distributed in accordance with a calendar year requirement; the
Funds intend to avoid the excise tax by making timely distributions.
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains derived from sales of portfolio securities held by a Fund will
generally be designated as long-term or short-term. Distributions from a
Fund's long-term capital gains are generally taxed at the long-term capital
gains rate regardless of how long you have owned shares in the Fund. Dividends
from other sources are generally taxed as ordinary income.
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from each Fund in which
you are a shareholder a statement of the amount and nature of the
distributions made to you during the year.
 
  If you redeem, transfer or exchange Fund shares, you may have taxable gain
or a loss. If you hold Fund shares for six months or less, and during that
time you receive a capital gain dividend, any loss you realize on the sale of
these Fund shares will be treated as a long-term loss to the extent of the
earlier distribution.
 
  Dividends and certain interest income earned from foreign securities by a
Fund may be subject to foreign withholding or other taxes. A Fund may be
permitted to pass on to its shareholders the right to a credit or deduction
for income or other tax credits earned from foreign investments and will do so
if possible. These deductions or credits may be subject to tax law
limitations.
 
  If a Fund invests in certain "passive foreign investment companies"
("PFICs"), it will be subject to Federal income tax (and possibly additional
interest charges) on a portion of any "excess distribution" or gain from the
disposition of such shares, even if it distributes such income to its
shareholders. If a Fund elects to treat a PFIC as a "qualified electing fund"
("QEF") and the PFIC furnishes certain financial information in the required
form to such Fund, the Fund will instead be required to include in income each
year its allocable share of the ordinary earnings and net capital gains of the
QEF, regardless of whether received, and such amounts will be subject to the
various distribution requirements described above. The Funds may also elect to
mitigate the tax effects of owning PFIC stock by making an annual mark-to-
market election with respect to PFIC shares.
 
                            ADDITIONAL INFORMATION
 
  SHAREHOLDER COMMUNICATIONS. You will receive unaudited Semi-Annual Reports
and audited Annual Reports on a regular basis from the Funds. In addition, you
will also receive updated Prospectuses or Supplements to this Prospectus. In
order to eliminate duplicate mailings, the Funds will only send one copy of
the above communications to (1) accounts with the same primary record owner,
(2) joint tenant accounts, (3) tenant in common accounts and (4) accounts
which have the same address.

                            FUND OPERATING EXPENSES
 
  The purpose of this table is to assist you in understanding the expenses
charged directly to the Fund, which investors in the Fund will bear indirectly
for the current fiscal year. Such expenses include payments to Trustees,
auditors, legal counsel and service providers (such as the Advisor),
registration fees and distribution fees. The expenses shown below are based on
expenses for the Fund's past fiscal year. Because of the 12b-1 fee, you may
over the long term pay more than the amount of the maximum permitted front-end
sales charge.

                                FUND INFORMATION
   
  This Prospectus describes Class A, Class B and Class C Shares of the Fund.
This section summarizes the Fund's principal investments. The sections entitled
"What are the Fund's Investments and Investment Practices?" and "What are the
Risks of Investing in the Fund?" and the SAI give more information about the
Fund's investment techniques and risks.     
 
  GOALS AND PRINCIPAL INVESTMENTS. The Fund's primary goal is to provide long-
term capital appreciation; its secondary goal is to provide income. Under
normal conditions, the Fund will invest at least 65% of its assets in Equity
Securities.
 
  In choosing Equity Securities the Advisor considers, among other factors:
 
  . the potential for accelerated earnings growth
 
  . the maintenance of a substantial competitive advantage
 
  . a focused management team
 
  . a stable balance sheet.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers employed
by the Advisor makes investment decisions for the Fund.
   
  The Fund is closed to new investors.     
 
                      WHO MAY WANT TO INVEST IN THE FUND?
 
  The Fund is designed for investors who desire potentially high capital
appreciation and who can accept short-term variations in return for potentially
greater returns over the long term. In general, the greater the risk, the
greater the potential reward. Investors who have a short time horizon, who
desire a high level of income or who are conservative in their investment
approach may wish to invest in other portfolios offered by the Trust.
 
           WHAT ARE THE FUND'S INVESTMENTS AND INVESTMENT PRACTICES?
   
  The Fund invests in EQUITY SECURITIES, which include common stocks, preferred
stocks, warrants and other securities convertible into common stocks. Many of
the common stocks the Fund will buy will not pay dividends; instead, stocks
will be bought for the potential that their prices will increase, providing
capital appreciation for the Fund. The value of Equity Securities will
fluctuate due to many factors, including the past and predicted earnings of the
issuer, the quality of the issuer's management, general market conditions, the
forecasts for the issuer's industry and the value of the issuer's assets.
Holders of Equity Securities only have rights to value in the company after all
debts have been paid, and they could lose their entire investment in a company
that encounters financial difficulty. Warrants are rights to purchase
securities at a specified time at a specified price.     
   
  The Fund may purchase AMERICAN DEPOSITARY RECEIPTS ("ADRS"), EUROPEAN
DEPOSITARY RECEIPTS ("EDRS") AND GLOBAL DEPOSITORY RECEIPTS ("GDRS"). ADRs are
issued by U.S. financial institutions and EDRs and GDRs are issued by European
financial institutions. They are receipts evidencing ownership of underlying
Foreign Securities.     
 
  The Fund may invest up to 25% of its assets in FOREIGN SECURITIES. Foreign
Securities are securities issued by non-U.S. companies and governments.
Investments in Foreign Securities are riskier than investments in U.S.
companies because (i) foreign companies may be subject to different accounting,
auditing and financial reporting standards than U.S. companies, (ii) there is
generally less public information available about foreign companies, (iii)
there may be less governmental regulation and supervision of foreign stock
exchanges, securities markets and companies and (iv) foreign securities may be
less liquid and more volatile than U.S. securities markets.
 
 
                                       8
<PAGE>
 
  The Fund may invest in FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS, which are
obligations of the Fund to purchase or sell a specific currency at a future
date at a set price. These contracts may decrease the Fund's loss due to a
change in currency value, but also limits gains from currency exchanges.
 
  The Fund may invest in FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.
Futures contracts are contracts in which the Fund agrees, at maturity, to make
delivery of or receive securities, the cash value of an index or foreign
currency. Futures contracts and options on futures contracts are used for
hedging purposes or to maintain liquidity. The Fund may not purchase or sell a
futures contract unless immediately after any such transaction the sum of the
aggregate amount of margin deposits on its existing futures positions and the
amount of premiums paid for related options is 5% or less of its total assets.
The Fund will set aside cash or other liquid securities to "cover" the Fund's
position in futures.
 
  The Fund may purchase or sell OPTIONS. The Fund may buy options giving it the
right to require a buyer to buy a security held by the Fund (put options), buy
options giving it the right to require a seller to sell securities to the Fund
(call options), sell (write) options giving a buyer the right to require the
Fund to buy securities from the buyer or write options giving a buyer the right
to require the Fund to sell securities to the buyer during a set time at a set
price. Options may relate to stock indices, individual securities, foreign
currencies or futures contracts. See the SAI for more details and additional
limitations.
 
  The Fund may purchase securities on a "WHEN-ISSUED" basis and may purchase or
sell securities on a "FORWARD COMMITMENT" basis. Although the price to be paid
by the Fund is set at the time of the agreement, the Fund usually does not pay
for the securities until they are received. The value of securities may change
between the time the price is set and payment. When the Fund purchases
securities for future delivery, the Fund's custodian will set aside cash or
liquid securities to "cover" the Fund's position. The Fund does not intend to
purchase securities for future delivery for speculative purposes.
 
  The Fund may enter into REPURCHASE AGREEMENTS. Under a repurchase agreement,
the Fund agrees to purchase securities from a seller and the seller agrees to
repurchase the securities at a later time, typically within seven days, at a
set price. The seller agrees to set aside collateral at least equal to the
repurchase price. This ensures that the Fund will receive the purchase price at
the time it is due, unless the seller defaults or declares bankruptcy, in which
event the Fund will bear the risk of possible loss due to adverse market action
or delays in liquidating the underlying obligation.
 
  The Fund may invest in REVERSE REPURCHASE AGREEMENTS. Under a reverse
repurchase agreement, the Fund sells securities and agrees to buy them back
later at an agreed upon time and price. Reverse repurchase agreements are used
to borrow money for temporary purposes.
 
  The Fund may LEND SECURITIES to broker-dealers and other financially sound
institutional investors who will pay the Fund for the use of the securities,
thus potentially increasing the Fund's returns. The borrower must set aside
cash or liquid securities equal to the value of the securities borrowed at all
times during the terms of the loan. Loans may not exceed 25% of the value of
the Fund's total assets. Risks involved in such transactions include possible
delay in recovering the loaned securities and possible loss of the securities
or the collateral if the borrower fails financially.
 
  The Fund may buy shares of registered MONEY MARKET FUNDS. The Fund will bear
a portion of the expenses of any investment company whose shares they purchase,
including operating costs and investment advisory, distribution and
administration fees. These expenses would be in addition to the Fund's own
expenses. The Fund may invest up to 10% of its assets in other investment
companies and no more than 5% of its assets in any one investment company.
 
  The Fund may invest in CASH EQUIVALENTS, which are high-quality, short-term
money market instruments including, among other things, commercial paper,
bankers' acceptances and negotiable certificates of deposit of banks or savings
and loan associations, short-term corporate obligations and short-term
securities issued by, or
 
                                       9

guaranteed by, the U.S. Government and its agencies or instrumentalities.
These instruments will be used primarily pending investment, to meet
anticipated redemptions or as a temporary defensive measure. If the Fund is
investing defensively, it may not be pursuing its investment objective.
 
  The Fund may purchase FIXED INCOME SECURITIES. Fixed Income Securities are
securities which either pay interest at set times at either fixed or variable
rates, or which realize a discount upon maturity. Fixed Income Securities
include corporate bonds, debentures, notes and other similar corporate debt
instruments, zero coupon bonds (discount debt obligations that do not make
interest payments) and variable amount master demand notes that permit the
amount of indebtedness to vary in addition to providing for periodic
adjustments in the interest rate. The Fund may purchase U.S. GOVERNMENT
SECURITIES, which are securities issued by, or guaranteed by, the U.S.
Government or its agencies or instrumentalities. Such securities include U.S.
Treasury bills, which have initial maturities of less than one year, U.S.
Treasury notes, which have initial maturities of one to ten years, U.S.
Treasury bonds, which generally have initial maturities of greater than ten
years, and obligations of the Federal Home Loan Mortgage Corporation, Federal
National Mortgage Association and Government National Mortgage Association.
Under normal market conditions, the Fund will not invest to a significant
extent, or on a routine basis, in U.S. Government Securities.
 
  The Fund may invest up to 5% of its total assets in LOWER-RATED DEBT
SECURITIES. Lower-Rated Debt Securities are securities that are rated below
investment grade by Standard & Poor's Rating Service, Moody's Investors
Service, Inc. or other nationally recognized rating agency. Such securities
are also known as "junk bonds" and are considered riskier than investment
grade securities.
 
  The Fund may invest up to 15% of the value of its net assets in ILLIQUID
SECURITIES. Illiquid Securities are securities for which there is no ready
market, which inhibits the ability to sell them and obtain their full market
value, or which are legally restricted as to their resale by the Fund.
 
  The Fund may BORROW MONEY in an amount up to 5% of its assets for temporary
purposes and in an amount up to 33 1/3% of its assets to meet redemptions.
This is a "fundamental" policy which can be changed only by shareholders.
 
  The Fund is classified as a "diversified fund." With respect to 75% of a
diversified Fund's assets, a diversified Fund cannot invest more than 5% of
its assets in a single issuer (other than U.S. Government and its agencies and
instrumentalities). In addition, a diversified Fund cannot invest more than
25% of its assets in a single issuer.
 
                 WHAT ARE THE RISKS OF INVESTING IN THE FUND?
 
  Investing in the Fund may be less risky than investing in individual stocks
due to the diversification of investing in a portfolio of many different
stocks; however, such diversification does not eliminate all risks. Because
the Fund invests mostly in Equity Securities, rises and falls in the stock
market in general, as well as in the value of particular Equity Securities
held by the Fund, can affect the Fund's performance. Your investment in the
Fund is not guaranteed. The net asset value of the Fund will change daily and
you might not recoup the amount you invest in the Fund.
 
  The Fund is not meant to provide a vehicle for playing short-term swings in
the stock market. Consistent with a long-term investment approach, investors
in the Fund should be prepared and able to maintain their investments during
periods of adverse market conditions. By itself, the Fund is a balanced
investment program and there is no guarantee that the Fund will achieve its
investment objective since there is uncertainty in every investment.
   
  A Fund's risk is mostly dependent on the types of securities it purchases
and its investment techniques. The Fund is authorized to use options, futures,
and forward foreign currency exchange contracts, which are types of derivative
instruments. Derivative instruments are instruments that derive their value
from a different underlying security, index or financial indicator. The use of
derivative instruments exposes the Fund to additional risks and     
 
                                      10
<PAGE>
 
   
transaction costs. Risks inherent in the use of derivative instruments
include: (1) the risk that interest rates, securities prices and currency
markets will not move in the direction that a portfolio manager anticipates;
(2) imperfect correlation between the price of derivative instruments and
movements in the prices of the securities, interest rates or currencies being
hedged; (3) the fact that skills needed to use these strategies are different
than those needed to select equity securities; (4) the possible absence of a
liquid secondary market for any particular instrument and possible exchange
imposed price fluctuation limits, either of which may make it difficult or
impossible to close out a position when desired; (5) leverage risk, that is,
the risk that adverse price movements in an instrument can result in a loss
substantially greater than the Fund's initial investment in that instrument
(in some cases, the potential loss is unlimited); and (6) particularly in the
case of privately-negotiated instruments, the risk that the counterparty will
not perform its obligations, which could leave the Fund worse off than if it
had not entered into the position.     
 
  To the extent that the Fund invests in illiquid securities, the Fund risks
not being able to sell securities at the time and the price that it would
like. The Fund may therefore have to lower the price, sell substitute
securities or forego an investment opportunity, each of which might adversely
affect the Fund.
 
  The risks of the various investment techniques the Fund uses are described
in more detail in the SAI.
 
                                  PERFORMANCE
 
                   HOW IS THE FUND'S PERFORMANCE CALCULATED?
 
  There are various ways in which the Fund may calculate and report its
performance. Performance is calculated separately for each class of shares.
 
  One method is to show the Fund's total return. Cumulative total return is
the percentage change in the value of an amount invested in a class of shares
of the Fund over a stated period of time and takes into account reinvested
dividends plus in the case of Class A Shares, the payment of the maximum sales
charge and, in the case of Class B and Class C Shares, the maximum CDSC.
Cumulative total return most closely reflects the actual performance of the
Fund. However, a shareholder who opts to receive dividends in cash, a Class A
shareholder who paid a sales charge lower than 5.5%, or a Class B or C
shareholder who paid lower than the maximum CDSC will have a different return
than the reported performance.
 
  Average annual total return refers to the average annual compounded rates of
return over a specified period on an investment in shares of the Fund
determined by comparing the initial amount invested to the ending redeemable
value of the amount, taking into account reinvested dividends, the payment of
the maximum sales charge on Class A Shares, and the payment of the maximum
CDSC on Class B and Class C Shares.
 
  The Fund may also publish its current yield. Yield is the net investment
income generated by a share of the Fund during a 30-day period divided by the
maximum offering price on the 30th day. "Maximum offering price" includes the
sales charge for Class A Shares.
 
  The Fund may sometimes publish total returns that do not take into account
sales charges and such returns will be higher than returns which include sales
charges. You should be aware that (i) past performance does not indicate how
the Fund will perform in the future; and (ii) the Fund's return and net asset
value will fluctuate, so you cannot necessarily use the Fund's performance
data to compare it to investment in certificates of deposit, savings accounts
or other investments that provide a fixed or guaranteed yield.
   
  The Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. The Fund may also compare its total return
to broad-based indices. These indices show the value of
    
                                      11
<PAGE>
 
   
selected portfolios of securities (assuming reinvestment of interest and
dividends) which are not managed by a portfolio manager. The Fund may report
how it is performing in comparison to the Consumer Price Index, an indication
of inflation reported by the U.S. Government.     
 
                     WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Fund's annual report dated June 30 of each year and semi-
annual report dated December 31 of each year, which will automatically be
mailed to shareholders. To obtain copies of financial reports or performance
information, call (800) 438-5789.
 
                       PURCHASES AND EXCHANGES OF SHARES
 
             WHICH SHARE CLASS SHOULD I CHOOSE FOR MY INVESTMENT?
 
  The Fund offers Class A, Class B and Class C Shares. Each Class has its own
cost structure, allowing you to choose the one that best meets your
requirements given the amount of your purchase and the intended length of your
investment. You should consider both ongoing annual expenses and initial or
contingent deferred sales charges in estimating the costs of investing in a
particular class of shares.

  The Fund issues Class K and Class Y Shares, which have different sales
charges, expense levels and performance. Class K and Class Y Shares are
available to limited types of investors. Call (800) 438-5789 to obtain more
information concerning Class K and Class Y Shares.
 
                        WHAT PRICE DO I PAY FOR SHARES?
   
  The purchase price for Class A Shares is the net asset value ("NAV") next
determined after we receive your order in proper form PLUS any applicable
sales charge. The purchase price for Class B and Class C Shares is the NAV
next determined. You should be aware that broker-dealers (other than the
Fund's Distributor) may charge investors additional fees if shares are
purchased through them.     
   
  Except in certain limited circumstances, the Fund determines its NAV on each
day the New York Stock Exchange ("NYSE") is open for trading (a "Business
Day") at the close of such trading on the NYSE (normally 4:00 p.m. Eastern
time). The Fund calculates NAV separately for each class of shares. NAV is
calculated by totaling the value of all of the assets of the Fund allocated to
a particular class of shares, subtracting the Fund's liabilities and expenses
charged to that class and dividing the result by the number of shares of that
class outstanding.

  APPLICABLE SALES CHARGE. Except in the circumstances described below, you
must pay a sales charge at the time of purchase of Class A Shares. The sales
charge as a percentage of your investment decreases as the amount you invest
increases. The current sales charge rates and commissions paid to selected
dealers are as follows:

   However, a CDSC of 1% is imposed on certain redemptions within one year of
   purchase. Class A Shares of the Trust Funds purchased on or before June 27,
   1995 are subject to a different CDSC, which is described in the SAI.
 
** The Distributor will pay a 1% commission to dealers who initiate and are
   responsible for purchases of $1 million or more.
 
  The Distributor may pay the entire commission to dealers. If that occurs,
the dealer may be considered an "underwriter" under Federal securities laws.
   
  SALES CHARGE WAIVERS. We will waive the initial sales charge on sales of
Class A Shares to the following types of purchasers:     
 
  (1) individuals with an investment account or relationship with the
      Advisor;
 
  (2) full-time employees and retired employees of the Advisor, employees of
      the Fund's service providers and immediate family members of such
      persons;
 
  (3) registered broker-dealers that have entered into selling agreements
      with the Distributor, for their own accounts or for retirement plans
      for their employees or sold to registered representatives for full-time
      employees (and their families) that certify to the Distributor at the
      time of purchase that such purchase is for their own account (or for
      the benefit of their families);
 
  (4) certain qualified employee benefit plans as described below;
 
  (5) individuals who reinvest a distribution from a qualified retirement
      plan for which the Advisor serves as investment advisor;
 
  (6) individuals who reinvest the proceeds of redemptions from Class Y
      Shares of any Fund of the Trust, the Company or Framlington, within 60
      days of redemption;
 
  (7) banks and other financial institutions that have entered into
      agreements with the Trust, the Company or Framlington to provide
      shareholder services for customers (including customers of such banks
      and other financial institutions, and the immediate family members of
      such customers);
 
  (8) fee-based financial planners or employee benefit plan consultants
      acting for the accounts of their clients;
 
  (9) employer sponsored retirement plans which are administered by Universal
      Pensions, Inc. ("UPI Plans"); and
     
  (10) employer sponsored 401(k) plans that are administered by Merrill Lynch
       Group Employee Services ("Merrill Lynch Plans") which meet the
       criteria described below under "Qualified Employer Sponsored
       Retirement Plans."     
 
                                      13

QUALIFIED EMPLOYER SPONSORED RETIREMENT PLANS
   
  We will waive the initial sales charge on purchases of Class A Shares by
employer sponsored retirement plans that are qualified under Section 401(a) or
Section 403(b) of the Code (each, a "Qualified Employee Benefit Plan") and
that (1) invest $1,000,000 or more in Class A Shares of investment portfolios
offered by the Trust, the Company or Framlington or (2) have at least 75
eligible plan participants. In addition, we will waive the CDSC of 1% charged
on certain redemptions within one year of purchase for Qualified Employee
Benefit Plan purchases that meet the above criteria. A 1% commission will be
paid by the Distributor to dealers and other entities (as permitted by
applicable Federal and state law) who initiate and are responsible for
Qualified Employee Benefit Plan purchases that meet the above criteria. For
purposes of this sales charge waiver, Simplified Employee Pension Plans
("SEPs"), Individual Retirement Accounts ("IRAs"), UPI Plans and Merrill Lynch
Plans are not considered to be Qualified Employee Benefit Plans.     
 
  We also will waive (i) the initial sales charge on Class A Shares on
purchases by UPI Plans for employees participating in an employer-sponsored or
administered retirement program operating under Section 408A of the Code and
(ii) the CDSC of 1% imposed on certain redemptions within one year of purchase
for these accounts. The Distributor will pay a 1% commission to dealers and
others (as permitted by applicable Federal and state law) who initiate and are
responsible for UPI Plan purchases.
 
  We will waive the initial sales charge for all investments by Merrill Lynch
Plans if (i) the Plan is recordkept on a daily valuation basis by Merrill
Lynch Group Employee Services ("Merrill Lynch") and, on the date the plan
sponsor (the "Plan Sponsor") signs the Merrill Lynch Recordkeeping Service
Agreement, the Plan has $3 million or more in assets invested in broker/dealer
funds not advised or managed by Merrill Lynch Asset Management, L.P. ("MLAM")
that are made available pursuant to a Services Agreement between Merrill Lynch
and the Fund's principal underwriter or distributor and in funds advised or
managed by MLAM (collectively, the "Applicable Investments"); or (ii) the Plan
is recordkept on a daily valuation basis by an independent recordkeeper whose
services are provided through a contract or alliance arrangement with Merrill
Lynch, and on the date the Plan Sponsor signs the Merrill Lynch Recordkeeping
Service Agreement, the Plan has $3 million or more in assets, excluding money
market funds, invested in Applicable Investments; or (iii) the Plan has 500 or
more eligible employees, as determined by the Merrill Lynch plan conversion
manager, on the date the Plan Sponsor signs the Merrill Lynch Recordkeeping
Service Agreement.
   
  SALES CHARGE REDUCTIONS. You may qualify for reduced sales charges in the
following cases:     
 
  . LETTER OF INTENT. If you intend to purchase at least $25,000 of Class A,
    Class B and Class C Shares of the Fund you may wish to complete the
    Letter of Intent Section of your Account Application Form. By doing so,
    you agree to invest a certain amount over a 13-month period. You would
    pay a sales charge on any Class A Shares you purchase during the 13
    months based on the total amount to be invested under the Letter of
    Intent. You can apply any investments you made in any of the funds during
    the preceding 90-day period toward fulfillment of the Letter of Intent
    (although there will be no refund of sales charges you paid during the
    90-day period). You should inform the Transfer Agent that you have a
    Letter of Intent each time you make an investment.
 
     You are not obligated to purchase the amount specified in the Letter of
   Intent. If you purchase less than the amount specified, however, you must
   pay the difference between the sales charge paid and the sales charge
   applicable to the purchases actually made. The Custodian will hold such
   amount in escrow. The Custodian will pay the escrowed funds to your
   account at the end of the 13 months unless you do not complete your
   intended investment.
 
  . QUANTITY DISCOUNTS. You may combine purchases of Class A Shares that are
    made by you, your spouse, your children under age 21 and your IRA when
    calculating the sales charge. You must notify your broker or the Transfer
    Agent to qualify.
 
  . RIGHT OF ACCUMULATION. You may add the value of any shares of non-money
    market funds of the Trust, the Company or Framlington you already own to
    the amount of your next Class A Share investment for purposes of
    calculating the sales charge at the time of current purchase. You must
    notify your broker or the Transfer Agent to qualify.

  . AUTOMATIC INVESTMENT PLAN ("AIP"). Under the AIP you may arrange for
    periodic investments in the Fund through automatic deductions from a
    checking or savings account. To enroll in the AIP you should complete the
    AIP Application Form or call the Fund at (800) 438-5789. The minimum pre-
    authorized investment amount is $50. You may discontinue the AIP at any
    time. We may discontinue the AIP on 30 days' written notice to you.
 
  . REINVESTMENT PRIVILEGE. Once a year you may reinvest redemption proceeds
    from Class A, B and C Shares of the Fund (or Class A, B and C Shares of
    another non-money market fund of the Trust, the Company or Framlington)
    in shares of the same class of the same Fund without any sales charges,
    if the reinvestment is made within 60 days of redemption. You or your
    broker must notify the Transfer Agent in writing at the time of
    reinvestment in order to eliminate the sales charge.
 
 
                                       15

  The Transfer Agent will send you confirmations of the opening of an account
and of all subsequent purchases, exchanges or redemptions in the account. If
your account has been set up by a broker or other investment professional,
account activity will be detailed in their statements to you.
 
  We do not issue share certificates. We reserve the right to (i) reject any
purchase order if, in our opinion, it is in the Fund's best interest to do so
and (ii) suspend the offering of shares of any class for any period of time.
 
  See the SAI for further information regarding purchases of the Fund's shares.
 
                           HOW CAN I EXCHANGE SHARES?
   
  You may exchange shares of the Fund for shares of the same class of other
funds of the Trust, the Company or Framlington based on their relative net
asset values. Class A Shares of a money market fund of the Trust or the Company
that were (1) acquired through the use of the exchange privilege and (2) can be
traced back to a purchase of shares in one or more funds of the Trust or the
Company for which a sales charge was paid, can be exchanged for Class A Shares
of a fund of the Trust, the Company or Framlington. Class B and Class C Shares
will continue to age from the date of the original purchase and will retain the
same CDSC rate as they had before the exchange.     
 
  You must meet the minimum purchase requirements for the fund of the Trust,
the Company or Framlington that you purchase by exchange. If you are exchanging
into shares of a fund with a higher sales charge, you must pay the difference
at the time of the exchange. Please note that a share exchange is a taxable
event and accordingly, you may realize a taxable gain or loss. Before making an
exchange request, read the Prospectus of the fund you wish to purchase by
exchange. You can obtain a Prospectus for any fund of the Trust, the Company or
Framlington by contacting your broker or the Funds at (800) 438-5789. Brokers
may charge a fee for handling exchanges.
 
  . EXCHANGES BY TELEPHONE. You may give exchange instructions by telephone
    to the Fund at (800) 438-5789. You may not exchange shares by telephone
    if you hold share certificates. We reserve the right to reject any
    telephone exchange request and to place restrictions on telephone
    exchanges.
     
  . EXCHANGES BY MAIL. You may send exchange orders to your broker or to the
    Transfer Agent at The Munder Funds c/o First Data Investor Services
    Group, P.O. Box 5130, Westborough, Massachusetts 01581-5130.     
 
  We may modify or terminate the exchange privilege at any time. You will be
given notice of any material modifications except where notice is not required.
 
                             REDEMPTIONS OF SHARES
                  
               WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?     
   
  The redemption price is the NAV next determined after we receive the
redemption request in proper form. We will reduce the amount you receive by the
amount of any applicable CDSC. See "Purchases of Shares--What Price Do I Pay
for Shares?" for an explanation of how the net asset value next determined is
calculated.     
 
CONTINGENT DEFERRED SALES CHARGES. You pay a CDSC when you redeem:
 
  . Class A Shares that are part of an investment of at least $1 million
    within one year of buying them
 
  . Class B Shares within six years of buying them
 
  . Class C Shares within one year of buying them.
 
                                       16

  These time periods include the time you held Class B or Class C Shares which
you may have exchanged for Class B or Class C Shares of the Fund.
   
  The CDSC schedule for Class B Shares purchased after June 27, 1995 is set
forth below. See the SAI for the CDSC schedule for Class B Shares purchased
before that time. The CDSC is based on the original net asset value at the time
of your investment or the net asset value at the time of redemption, whichever
is lower.

  The Distributor pays sales commissions of 4.00% of the purchase price of
Class B Shares of the Fund to brokers at the time of sale that initiate and are
responsible for purchases of such Class B Shares of the Fund.
 
  You will not pay a CDSC to the extent that the value of the redeemed shares
represents:
 
  . reinvestment of dividends or capital gains distributions
 
  . capital appreciation of shares redeemed.
 
  When you redeem shares, we will assume that you are redeeming first shares
representing reinvestment of dividends and capital gains distributions, then
any appreciation on shares redeemed, and then remaining shares held by you for
the longest period of time. We will calculate the holding period of shares of
the Fund acquired through an exchange of shares of the Munder Money Market Fund
from the date that the shares of the Fund were initially purchased.
 
  CDSC WAIVERS. We will waive the CDSC payable upon redemptions of shares which
you purchased after June 27, 1995 for:
 
  . redemptions made within one year after the death of a shareholder or
    registered joint owner
 
  . minimum required distributions made from an IRA or other retirement plan
    account after you reach age 70 1/2
 
  . involuntary redemptions made by the Fund
 
  . redemptions limited to 10% per year of an account's NAV. For example, if
    you maintain an annual balance of $10,000 you can redeem up to $1,000
    annually free of charge.
 
  Consult the SAI for Class B Share CDSC waivers which apply when you redeem
shares acquired in an exchange of shares of another Fund of the Company or the
Trust that were purchased on or before June 27, 1995.
 
  We will waive the CDSC for Class B Shares for all redemptions by Merrill
Lynch Plans if: (i) the Plan is recordkept on a daily valuation basis by
Merrill Lynch; or (ii) the Plan is recordkept on a daily valuation basis by an
independent recordkeeper whose services are provided through a contract or
alliance arrangement with Merrill Lynch; or (iii) the Plan has less than 500
eligible employees, as determined by the Merrill Lynch plan conversion manager,
on the date the Plan Sponsor signs the Merrill Lynch Recordkeeping Service
Agreement.

<PAGE>
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. The Fund may temporarily stop
redeeming shares when the NYSE is closed or trading on the NYSE is restricted,
when an emergency exists and the Fund cannot sell its assets or accurately
determine the value of its assets or if the SEC orders the Fund to suspend
redemptions.
 
                           HOW CAN I REDEEM SHARES?
 
  You may redeem shares of the Fund in several ways:
     
  . BY MAIL. You may mail your redemption request to: THE MUNDER FUNDS C/O
    FIRST DATA INVESTOR SERVICES GROUP, P.O. BOX 5130, WESTBOROUGH,
    MASSACHUSETTS 01581-5130. The redemption request should state the name of
    the Fund, share class, account number, amount of redemption, account name
    and where to send the proceeds. All account owners must sign. If a share
    certificate has been issued to you, you must endorse the share
    certificate and return it together with the written redemption request.
        
  . A SIGNATURE GUARANTEE is required for the following redemption requests:
    (a) redemptions proceeds greater than $50,000; (b) redemption proceeds
    not being made payable to the owner of the account; (c) redemption
    proceeds not being mailed to the address of record on the account or (d)
    if the redemption proceeds are being transferred to another Munder Funds
    account with a different registration. You can obtain a signature
    guarantee from a financial institution such as a commercial bank, trust
    company, savings association or from a securities firm having membership
    on a recognized securities exchange.
 
  . BY TELEPHONE. You can redeem your shares by calling your broker or the
    Fund at (800) 438-5789. There is no minimum requirement for telephone
    redemptions paid by check. The Transfer Agent may deduct a wire fee
    (currently $7.50) for wire redemptions under $5,000.
 
     If you are redeeming at least $1,000 of shares and you have authorized
   expedited redemption on your Account Application Form, simply call the
   Fund prior to 4:00 p.m. (Eastern Time), and request the funds be mailed
   to the commercial bank or registered broker-dealer you designated on your
   Account Application Form. We will send your redemption amount to you on
   the next Business Day. We reserve the right at any time to change or
   impose fees for this expedited redemption procedure.
 
     We record all telephone calls for your protection and take measures to
   identify the caller. If the Transfer Agent properly acts on telephone
   instructions and follows the reasonable procedures to ensure against
   unauthorized transactions, neither the Trust, the Company, the
   Distributor nor the Transfer Agent will be responsible for any losses. If
   these procedures are not followed, the Transfer Agent may be liable to
   you for losses resulting from unauthorized instructions.
 
     During periods of unusual economic or market activity, you may
   experience difficulties or delays in effecting telephone redemptions. In
   such cases you should consider placing your redemption request by mail.
 
  . AUTOMATIC WITHDRAWAL PLAN ("AWP"). If you have an account value of $2,500
    or more in the Fund, you may redeem shares on a monthly, quarterly, semi-
    annual or annual basis. The minimum withdrawal is $50. We usually process
    withdrawals on the 20th day of the month and promptly send you your
    redemption amount. You may enroll in the AWP by completing the AWP
    Application Form available through the Transfer Agent. To participate in
    the AWP you must have your dividends automatically reinvested and may not
    hold share certificates. You may change or cancel the AWP at any time
    upon notice to the Transfer Agent. You should not buy Class A Shares (and
    pay a sales charge) while you participate in the AWP and you must pay any
    applicable CDSC's when you redeem shares.
 
  . INVOLUNTARY REDEMPTION. We may redeem your account if its value falls
    below $250 as a result of redemptions (but not as a result of a decline
    in net asset value). You will be notified in writing and allowed 60 days
    to increase the value of your account to the minimum investment level.

<PAGE>
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  We will typically send redemption amounts to you within seven Business Days
after you redeem shares. We may hold redemption amounts from the sale of
shares you purchased by check until the purchase check has cleared, which may
be as long as 15 days.
 
                     STRUCTURE AND MANAGEMENT OF THE FUND
 
                          HOW IS THE FUND STRUCTURED?
   
  The Trust is an open-end management investment company, which is a mutual
fund that sells and redeems shares every day that it is open for business. The
Trust is managed under the direction of its governing Board of Trustees, which
is responsible for the overall management of the Trust and supervises the
Fund's service providers. The Trust is organized as a Massachusetts business
trust.     
 
                      WHO MANAGES AND SERVICES THE FUND?
   
  INVESTMENT ADVISOR. The Fund's investment advisor is Munder Capital
Management, a Delaware general partnership with its principal offices at 480
Pierce Street, Birmingham, Michigan 48009. The principal partners of the
Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM Holdings
II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware corporation
and was a registered investment advisor. WAM and WAM II are Delaware
corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,
1998, the Advisor and its affiliates had approximately $48.2 billion in assets
under management, of which $25.4 billion were invested in equity securities,
$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion
in non-discretionary assets.     
 
  The Advisor provides overall investment management and research and credit
analysis for the Fund and is responsible for all purchases and sales of
portfolio securities for the Fund.
 
  During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate of 0.75% of the average daily net assets of the Fund
(after waivers, if any).
   
  The Advisor may, from time to time, make payments to banks, broker-dealers
or other financial institutions for certain services to the Fund and/or its
shareholders, including sub-administration, sub-transfer agency and
shareholder servicing. The Advisor may make such payments out of its own
resources and there are no additional costs to the Fund or its shareholders.
    
  The Advisor selects broker-dealers to execute portfolio transactions for the
Fund based on best price and execution terms. The Advisor may consider as a
factor the number of shares sold by the broker-dealer.
   
  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Fund's
transfer agent. The Transfer Agent is a wholly owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
05181-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Fund's administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Trust in all aspects of its administration and operations including
overseeing the maintenance of financial records and fund accounting. As
compensation for its services for the Trust, State Street is entitled to
receive fees, based on the aggregate daily net assets of the Fund and certain
other investment portfolios that are advised by the Advisor for which it
provides services, computed daily and payable monthly at the annual rate of
0.113% on the first $2.8 billion of net assets, plus 0.103% on the next $2.2
billion of net assets, plus 0.101% on
 
                                      19
<PAGE>
 
the next $2.5 billion of net assets, plus 0.095% on the next $2.5 billion of
net assets, plus 0.080% on the next $2.5 billion of net assets, plus 0.070% on
all net assets in excess of $12.5 billion (with a $75,000 minimum fee per annum
in the aggregate for all portfolios with respect to the Administrator).
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Fund. State Street pays the Distributor a fee for
these services out of its own resources at no cost to the Fund.
 
  CUSTODIAN AND SUB-CUSTODIAN. Comerica Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Fund's custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Fund beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Funds. State Street serves as the Fund's sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Fund's shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Fund's shares.
 
  For an additional description of the services performed by the Administrator,
the Transfer Agent, the Custodian, the Sub-Custodian and the Distributor, see
the SAI.
   
  YEAR 2000. The Fund's operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Fund. The Fund has been informed
that its major service providers have made compliance with the Year 2000 Issue
a high priority and are taking steps that they believe are reasonably designed
to address the Year 2000 Issue with respect to their computer systems. There
can be, however, no assurance that these steps will be successful, or that
interaction with other non-complying computer systems will not impair their
services at that time.     
 
DISTRIBUTION SERVICES ARRANGEMENT
 
  Under Rule 12b-1 of the 1940 Act, the Fund has adopted a Service Plan with
respect to its Class A Shares and Service and Distribution Plans with respect
to its Class B and Class C Shares. Under the Plans, the Fund uses its assets to
finance activities relating to the distribution of its shares to investors and
the provision of certain shareholder services. The Distributor is paid a
service fee at an annual rate of up to 0.25% of the value of average daily net
assets of the Fund's Class A Shares. The Distributor also is paid a service fee
at an annual rate of 0.25% and a distribution fee at an annual rate of up to
0.75% of the value of the average daily net assets of the Fund's Class B and
Class C Shares. The Distributor uses the service fees primarily to pay ongoing
trail commissions to securities dealers (which may include the Distributor
itself) and other financial organizations which provide shareholder services
for the Funds. These services include, among other things, processing new
shareholder account applications, reporting to the Fund's Transfer Agent all
transactions by customers and serving as the primary information source to
customers concerning the Fund.
 
                      WHAT ARE MY RIGHTS AS A SHAREHOLDER?
   
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
the Trust as a whole and affecting the Fund. You will not vote by class unless
expressly required by law or when the Trustees determine the matter to be voted
on affects only the interests of the holders of a particular class of shares.
The Trust will not hold an annual shareholder meeting, but special meetings may
be held at the written request of shareholders owning more than 10% of
outstanding shares for the purpose of removing a Trustee. Under Massachusetts
law, it is possible that a shareholder may be personally liable for the Trust's
obligations. If a shareholder were required to pay a debt of the Fund, however,
the Trust has committed to reimburse the shareholder in full from their assets.
The SAI contains more information regarding voting rights.     
 
                                       20
<PAGE>
 
  Comerica currently has the right to vote a majority of the outstanding shares
of the Fund as agent, custodian or trustee for its customers and therefore it
is considered to be a controlling person of the Trust.
 
                       DIVIDENDS, DISTRIBUTIONS AND TAXES
 
                WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUND?
 
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on the Fund's investments. The Fund passes its earnings along to
investors in the form of dividends. Dividend distributions are the dividends or
interest earned on investments after expenses. The Fund pays dividends
quarterly. The Fund distributes its net realized capital gains (including net
short-term capital gains), if any, at least annually.
 
  It is possible that the Fund may make a distribution in excess of the Fund's
current and accumulated earnings and profits. You will treat such a
distribution as a return of capital which is applied against and reduces your
basis in your shares. You will treat the excess of any such distribution over
your basis in your shares as gain from a sale or exchange of the shares.
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Fund will pay dividend and capital gains distributions in additional
shares of the same class of the Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Fund at (800) 438-5789.
 
           ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUND?
   
  This section contains a brief summary of the tax implications of ownership in
the Fund's shares. A more detailed discussion about the tax treatment of
distributions from the Fund and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Fund, is contained in the SAI. You should consult
your tax advisor regarding the impact of owning the Fund's shares on your own
personal tax situation including the applicability of any state and local
taxes.     
   
  In general, as long as the Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. The Fund intends to qualify
annually as a RIC. Even if it qualifies as a RIC, the Fund may still be liable
for any excise tax on income that is not distributed in accordance with a
calendar year requirement; the Fund intends to avoid the excise tax by making
timely distributions.     
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains derived from sales of portfolio securities held by the Fund
will generally be designated as long-term or short-term. Distributions from the
Fund's long-term capital gains are generally taxed at the long-term capital
gains rate regardless of how long you have owned shares in the Fund. Dividends
from other sources are generally taxed as ordinary income.
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from the Fund a statement
of the amount and nature of the distributions made to you during the year.
 
  If you redeem, transfer or exchange Fund shares, you may have taxable gain or
a loss. If you hold Fund shares for six months or less, and during that time
you receive a capital gain dividend, any loss you realize on the sale of these
Fund shares will be treated as a long-term loss to the extent of the earlier
distribution.
 
                                       21
<PAGE>
 
  Dividends and certain interest income earned from foreign securities by the
Fund may be subject to foreign withholding or other taxes. The Fund may be
permitted to pass on to its shareholders the right to a credit or deduction for
income or other tax credits earned from foreign investments and it intends to
do so if possible. These deductions or credits may be subject to tax law
limitations.
 
  If the Fund invests in certain "passive foreign investment companies"
("PFICs"), it will be subject to Federal income tax (and possibly additional
interest charges) on a portion of any "excess distribution" or gain from the
disposition of such shares, even if it distributes such income to its
shareholders. If the Fund elects to treat PFIC as a "qualified electing fund"
("QEF") and the PFIC furnishes certain financial information in the required
form to such Fund, the Fund will instead be required to include in income each
year its allocable share of the ordinary earnings and net capital gains of the
QEF, regardless of whether received, and such amounts will be subject to the
various distribution requirements described above. The Fund may also elect to
mitigate the tax effects of owning PFIC stock by making an annual mark-to-
market election with respect to PFIC shares.
 
                             ADDITIONAL INFORMATION
 
  SHAREHOLDER COMMUNICATIONS. You will receive unaudited Semi-Annual Reports
and audited Annual Reports on a regular basis from the Fund. In addition, you
will also receive updated Prospectuses or Supplements to this Prospectus. In
order to eliminate duplicate mailings the Fund will only send one copy of the
above communications to (1) accounts with the same primary record owner, (2)
joint tenant accounts, (3) tenant in common accounts and (4) accounts which
have the same address.

                  WHAT ARE THE KEY FACTS REGARDING THE FUND?
 
Q: What is the Fund's goal?
 
A: The Accelerating Growth Fund primarily seek to provide long-term capital
appreciation.
 
Q: What is the Fund's strategy?
 
A: The Fund invests primarily in equity securities. "Equity Securities"
include common stocks, preferred stocks, warrants and other securities
convertible into common stock.
 
Q: What are the Fund's risks?
 
A: The Fund's net asset value, which is determined on every business day, will
change daily. The net asset value changes are due to changes in the price of
securities owned by the Fund as a result of rises and falls in the stock
market in general, changes in stock prices of particular companies and
perceptions about particular industries. The Fund may invest in emerging
growth companies which may involve greater price volatility and risk than more
established companies. You should note that you could lose a portion of the
amount you invest in the Fund.
 
Q: What are the options for investment in the Fund?
 
A: The Fund offers five different investment options, or classes: Class A, B,
C, K and Y. Class A, B, C and Y Shares are offered in other prospectuses.
 
Q: How do I buy and sell shares of the Fund?
 
A: Class K Shares of the Fund are available to customers ("Customers") of
banks and other institutions, and the immediate family members of such
Customers, that have entered into agreements with us to provide shareholder
services for Customers. You may purchase shares through such a bank or
financial institution.
 
  Shares may be redeemed (sold back to the Fund) through your bank or
financial institution.
 
  You may also acquire the Fund's shares by exchanging shares of the same
class of other funds of the Trust, The Munder Funds, Inc. (the "Company") and
The Munder Framlington Funds Trust ("Framlington"), and exchange Fund shares
for shares of the same class of other funds of the Trust, the Company and
Framlington.
 
Q: When and how are distributions made?
   
A: Dividend distributions are made from the dividends and interest earned on
investments after expenses. The Fund pays dividends at least quarterly (if
income is available) and distributes capital gains, if any, at least annually.
Unless you elect to receive distributions in cash, all dividends and capital
gain distributions of the Fund will be automatically used to purchase
additional shares of the Fund.     
 
Q: Who manages the Fund's assets?
 
A: Munder Capital Management is the Fund's investment advisor. The Advisor is
responsible for all purchases and sales of the securities held by the Fund.

                                FUND INFORMATION
 
  This Prospectus describes Class K Shares of the Fund. This section summarizes
the Fund's principal investments. The sections entitled "What are the Fund's
Investments and Investment Practices?" and "What are the Risks of Investing in
the Fund?" and the SAI give more information about the Fund's investment
techniques and risks.
       
  GOALS AND PRINCIPAL INVESTMENTS. The Fund's primary goal is to provide long-
term capital appreciation; its secondary goal is to provide income. Under
normal conditions, the Fund will invest at least 65% of its assets in Equity
Securities.
 
  In choosing Equity Securities, the Advisor considers, among other factors:
 
  . the potential for accelerated earnings growth
 
  . the maintenance of a substantial competitive advantage
 
  . a focused management team
 
  . a stable balance sheet.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers employed
by the Advisor makes investment decisions for the Fund.
   
  The Fund is closed to new investors.     
 
                      WHO MAY WANT TO INVEST IN THE FUND?
 
  The Fund is designed for investors who desire potentially high capital
appreciation and who can accept short-term variations in return for potentially
greater returns over the long term. In general, the greater the risk, the
greater the potential reward. Investors who have a short time horizon, who
desire a high level of income or who are conservative in their investment
approach may wish to invest in other portfolios offered by the Trust.
 
           WHAT ARE THE FUND'S INVESTMENTS AND INVESTMENT PRACTICES?
 
  The Fund invests in EQUITY SECURITIES, which include common stocks, preferred
stocks, warrants and other securities convertible into common stocks. Many of
the common stocks the Fund will buy will not pay dividends; instead, stocks
will be bought for the potential that their prices will increase, providing
capital appreciation for the Fund. The value of Equity Securities will
fluctuate due to many factors, including the past and predicted earnings of the
issuer, the quality of the issuer's management, general market conditions, the
forecasts for the issuer's industry and the value of the issuer's assets.
Holders of Equity Securities only have rights to value in the company after all
debts have been paid, and they could lose their entire investment in a company
that encounters financial difficulty. Warrants are rights to purchase
securities at a specified time at a specified price.
 
  The Fund may purchase AMERICAN DEPOSITARY RECEIPTS ("ADRS"), EUROPEAN
DEPOSITARY RECEIPTS ("EDRS") AND GLOBAL DEPOSITORY RECEIPTS ("GDRS"). ADRs are
issued by U.S. financial institutions and EDRs and GDRs are issued by European
financial institutions. They are receipts evidencing ownership of underlying
Foreign Securities.
 
  The Fund may invest up to 25% of its assets in FOREIGN SECURITIES. Foreign
Securities are securities issued by non-U.S. companies and governments.
Investments in Foreign Securities are riskier than investments in U.S.
companies because (i) foreign companies may be subject to different accounting,
auditing and financial reporting standards than U.S. companies, (ii) there is
generally less public information available about foreign companies, (iii)
there may be less governmental regulation and supervision of foreign stock
exchanges, securities markets and companies and (iv) foreign securities may be
less liquid and more volatile than U.S. securities markets.
 
                                       6
<PAGE>
 
  The Fund may invest in FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS, which
are obligations of the Fund to purchase or sell a specific currency at a
future date at a set price. These contracts may decrease the Fund's loss due
to a change in currency value, but also limits gains from currency exchanges.
 
  The Fund may invest in FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.
Futures contracts are contracts in which the Fund agrees, at maturity, to make
delivery of or receive securities, the cash value of an index or foreign
currency. Futures contracts and options on futures contracts are used for
hedging purposes or to maintain liquidity. The Fund may not purchase or sell a
futures contract unless immediately after any such transaction the sum of the
aggregate amount of margin deposits on its existing futures positions and the
amount of premiums paid for related options is 5% or less of its total assets.
The Fund will set aside cash or other liquid securities to "cover" the Fund's
position in futures.
 
  The Fund may purchase or sell OPTIONS. The Fund may buy options giving it
the right to require a buyer to buy a security held by the Fund (put options),
buy options giving it the right to require a seller to sell securities to the
Fund (call options), sell (write) options giving a buyer the right to require
the Fund to buy securities from the buyer or write options giving a buyer the
right to require the Fund to sell securities to the buyer during a set time at
a set price. Options may relate to stock indices, individual securities,
foreign currencies or futures contracts. See the SAI for more details and
additional limitations.
 
  The Fund may purchase securities on a "WHEN-ISSUED" basis and may purchase
or sell securities on a "FORWARD COMMITMENT" basis. Although the price to be
paid by the Fund is set at the time of the agreement, the Fund usually does
not pay for the securities until they are received. The value of securities
may change between the time the price is set and payment. When the Fund
purchases securities for future delivery, the Fund's custodian will set aside
cash or liquid securities to "cover" the Fund's position. The Fund does not
intend to purchase securities for future delivery for speculative purposes.
 
  The Fund may enter into REPURCHASE AGREEMENTS. Under a repurchase agreement,
the Fund agrees to purchase securities from a seller and the seller agrees to
repurchase the securities at a later time, typically within seven days, at a
set price. The seller agrees to set aside collateral at least equal to the
repurchase price. This ensures that the Fund will receive the purchase price
at the time it is due, unless the seller defaults or declares bankruptcy, in
which event the Fund will bear the risk of possible loss due to adverse market
action or delays in liquidating the underlying obligation.
 
  The Fund may invest in REVERSE REPURCHASE AGREEMENTS. Under a reverse
repurchase agreement, the Fund sells securities and agrees to buy them back
later at an agreed upon time and price. Reverse repurchase agreements are used
to borrow money for temporary purposes.
 
  The Fund may LEND SECURITIES to broker-dealers and other financially sound
institutional investors who will pay the Fund for the use of the securities,
thus potentially increasing the Fund's returns. The borrower must set aside
cash or liquid securities equal to the value of the securities borrowed at all
times during the terms of the loan. Loans may not exceed 25% of the value of
the Fund's total assets. Risks involved in such transactions include possible
delay in recovering the loaned securities and possible loss of the securities
or the collateral if the borrower fails financially.
 
  The Fund may buy shares of registered MONEY MARKET FUNDS. The Fund will bear
a portion of the expenses of any investment company whose shares they
purchase, including operating costs and investment advisory, distribution and
administration fees. These expenses would be in addition to the Fund's own
expenses. The Fund may invest up to 10% of its assets in other investment
companies and no more than 5% of its assets in any one investment company.
   
  The Fund may invest in CASH EQUIVALENTS, which are high-quality, short-term
money market instruments including, among other things, commercial paper,
bankers' acceptances and negotiable certificates of deposit of banks or
savings and loan associations, short-term corporate obligations and short-term
securities issued by, or     
 
                                       7
<PAGE>
 
   
guaranteed by, the U.S. Government and its agencies or instrumentalities.
These instruments will be used primarily pending investment, to meet
anticipated redemptions or as a temporary defensive measure. If the Fund is
investing defensively, it may not be pursuing its investment objective.     
 
  The Fund may purchase FIXED INCOME SECURITIES. Fixed Income Securities are
securities which either pay interest at set times at either fixed or variable
rates, or which realize a discount upon maturity. Fixed Income Securities
include corporate bonds, debentures, notes and other similar corporate debt
instruments, zero coupon bonds (discount debt obligations that do not make
interest payments) and variable amount master demand notes that permit the
amount of indebtedness to vary in addition to providing for periodic
adjustments in the interest rate. The Fund may purchase U.S. GOVERNMENT
SECURITIES, which are securities issued by, or guaranteed by, the U.S.
Government or its agencies or instrumentalities. Such securities include U.S.
Treasury bills, which have initial maturities of less than one year, U.S.
Treasury notes, which have initial maturities of one to ten years, U.S.
Treasury bonds, which generally have initial maturities of greater than ten
years, and obligations of the Federal Home Loan Mortgage Corporation, Federal
National Mortgage Association and Government National Mortgage Association.
Under normal market conditions, the Fund will not invest to a significant
extent, or on a routine basis, in U.S. Government Securities.
 
  The Fund may invest up to 5% of its total assets in LOWER-RATED DEBT
SECURITIES. Lower-Rated Debt Securities are securities that are rated below
investment grade by Standard & Poor's Rating Service, Moody's Investors
Service, Inc. or other nationally recognized rating agency. Such securities
are also known as "junk bonds" and are considered riskier than investment
grade securities.
 
  The Fund may invest up to 15% of the value of its net assets in ILLIQUID
SECURITIES. Illiquid Securities are securities for which there is no ready
market, which inhibits the ability to sell them and obtain their full market
value, or which are legally restricted as to their resale by the Fund.
 
  The Fund may BORROW MONEY in an amount up to 5% of its assets for temporary
purposes and in an amount up to 33 1/3% of its assets to meet redemptions.
This is a "fundamental" policy which can be changed only by shareholders.
 
  The Fund is classified as a "diversified fund." With respect to 75% of a
diversified Fund's assets, a diversified Fund cannot invest more than 5% of
its assets in a single issuer (other than U.S. Government and its agencies and
instrumentalities). In addition, a diversified Fund cannot invest more than
25% of its assets in a single issuer.
 
                 WHAT ARE THE RISKS OF INVESTING IN THE FUND?
 
  Investing in the Fund may be less risky than investing in individual stocks
due to the diversification of investing in a portfolio of many different
stocks; however, such diversification does not eliminate all risks. Because
the Fund invests mostly in Equity Securities, rises and falls in the stock
market in general, as well as in the value of particular Equity Securities
held by the Fund, can affect the Fund's performance. Your investment in the
Fund is not guaranteed. The net asset value of the Fund will change daily and
you might not recoup the amount you invest in the Fund.
 
  Consistent with a long-term investment approach, investors in the Fund
should be prepared and able to maintain their investments during periods of
adverse market conditions. By itself, the Fund is a balanced investment
program and there is no guarantee that the Fund will achieve its investment
objective since there is uncertainty in every investment.
 
  A Fund's risk is mostly dependent on the types of securities it purchases
and its investment techniques. The Fund is authorized to use options, futures,
and forward foreign currency exchange contracts, which are types of derivative
instruments. Derivative instruments are instruments that derive their value
from a different underlying security, index or financial indicator. The use of
derivative instruments exposes the Fund to additional risks and transaction
costs. Risks inherent in the use of derivative instruments include: (1) the
risk that interest rates,
 
                                       8
<PAGE>
 
   
securities prices and currency markets will not move in the direction that a
portfolio manager anticipates; (2) imperfect correlation between the price of
derivative instruments and movements in the prices of the securities, interest
rates or currencies being hedged; (3) the fact that skills needed to use these
strategies are different than those needed to select portfolio securities; (4)
the possible absence of a liquid secondary market for any particular
instrument and possible exchange imposed price fluctuation limits, either of
which may make it difficult or impossible to close out a position when
desired; (5) leverage risk, that is, the risk that adverse price movements in
an instrument can result in a loss substantially greater than the Fund's
initial investment in that instrument (in some cases, the potential loss is
unlimited); and (6) particularly in the case of privately-negotiated
instruments, the risk that the counterparty will not perform its obligations,
which could leave the Fund worse off than if it had not entered into the
position.     
 
  To the extent that the Fund invests in illiquid securities, the Fund risks
not being able to sell securities at the time and the price that it would
like. The Fund may therefore have to lower the price, sell substitute
securities or forego an investment opportunity, each of which might adversely
affect the Fund.
 
  The risks of the various investment techniques the Fund uses are described
in more detail in the SAI.
 
                                  PERFORMANCE
 
                   HOW IS THE FUND'S PERFORMANCE CALCULATED?
 
  There are various ways in which the Fund may calculate and report its
performance. Performance is calculated separately for each class of shares.
 
  One method is to show the Fund's total return. Cumulative total return is
the percentage change in the value of an amount invested in a class of shares
of the Fund over a stated period of time and takes into account reinvested
dividends. Cumulative total return most closely reflects the actual
performance of the Fund.
 
  Average annual total return refers to the average annual compounded rates of
return over a specified period on an investment in shares of the Fund
determined by comparing the initial amount invested to the ending redeemable
value of the amount, taking into account reinvested dividends.
 
  The Fund may also publish its current yield. Yield is the net investment
income generated by a share of the Fund during a 30-day period divided by the
maximum offering price on the 30th day.
 
  You should be aware that (i) past performance does not indicate how the Fund
will perform in the future; and (ii) the Fund's return and net asset value
will fluctuate, so you cannot necessarily use the Fund's performance data to
compare it to investment in certificates of deposit, savings accounts or other
investments that provide a fixed or guaranteed yield.
 
  The Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. The Fund may also compare its total return
to other broad-based indices. These indices show the value of selected
portfolios of securities (assuming reinvestment of interest and dividends)
which are not managed by a portfolio manager. The Fund may report how it is
performing in comparison to the Consumer Price Index, an indication of
inflation reported by the U.S. Government.
 
                     WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Fund's annual report dated June 30 of each year
 
                                       9
<PAGE>
 
and semi-annual report dated December 31 of each year, which will
automatically be mailed to shareholders. To obtain copies of financial reports
or performance information, call (800) 438-5789.
 
                              PURCHASES OF SHARES
 
  Customers of banks and other institutions, and the immediate family members
of such Customers, that have entered into agreements with us to provide
shareholder services for Customers may purchase Class K Shares. Customers may
include individuals, trusts, partnerships and corporations. The Fund also
issues other classes of shares, which have different sales charges, expense
levels and performance. Call (800) 438-5789 to obtain more information
concerning the Fund's other classes of shares.
 
                        WHAT PRICE DO I PAY FOR SHARES?
   
  The purchase price for Class K Shares is the net asset value ("NAV") next
determined after we receive your order in proper form. Except in certain
limited circumstances, the Fund determines its NAV on each day the New York
Stock Exchange ("NYSE") is open for trading (a "Business Day") at the close of
such trading on the NYSE (normally 4:00 p.m. Eastern time). The Fund
calculates NAV separately for each class of shares. NAV is calculated by
totaling the value of all of the assets of the Fund allocated to a particular
class of shares, subtracting the Fund's liabilities and expenses charged to
that class and dividing the result by the number of shares of that class
outstanding.     
 
                          WHEN CAN I PURCHASE SHARES?
 
  Shares of the Fund are sold on a continuous basis and can be purchased on
any Business Day.
 
                          HOW CAN I PURCHASE SHARES?
 
  All share purchases are effected through a Customer's account at an
institution and confirmations of share purchases will be sent to the
institution involved. Institutions (or their nominees) will normally be the
holders of record of Fund shares acting on behalf of their Customers, and will
reflect their Customers' beneficial ownership of shares in the account
statements provided by them to their Customers.
   
  We do not issue share certificates. We reserve the right to (i) reject any
purchase order if, in our opinion, it is in the Fund's best interest to do so
and (ii) suspend the offering of shares of any class for any period of time.
    
  You may pay for shares of the Fund with securities which the Fund is allowed
to hold.
 
                             REDEMPTIONS OF SHARES
 
                 WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?
 
  The redemption price is the NAV next determined after we receive the
redemption request in proper form.
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. The Fund may temporarily stop
redeeming shares when the NYSE is closed or trading on the NYSE is restricted,
when an emergency exists and the Fund cannot sell its assets or accurately
determine the value of its assets or if the SEC orders the Fund to suspend
redemptions.
 
                           HOW CAN I REDEEM SHARES?
 
  Redemption orders are effected at the NAV per share next determined after
receipt of the order by the Transfer Agent. Shares held by an institution on
behalf of its Customers must be redeemed in accordance with instructions and
limitations pertaining to the account at that institution.
 
                                      10
<PAGE>
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  If we receive a redemption order for the Fund before 4:00 p.m. (Eastern
time) on a Business Day, we will normally wire payment to the redeeming
institution on the next Business Day. We may delay wiring redemption proceeds
for up to seven days if we feel an earlier payment would have a negative
impact on the Fund.
 
                     STRUCTURE AND MANAGEMENT OF THE FUND
 
                          HOW IS THE FUND STRUCTURED?
 
  The Trust is an open-end management investment company, which is a mutual
fund that sells and redeems shares every day that it is open for business. It
is managed under the direction of its governing Board of Trustees, which is
responsible for the overall management of the Trust and supervise the Fund's
service providers. The Trust is organized as a Massachusetts business trust.
 
                      WHO MANAGES AND SERVICES THE FUND?
   
  INVESTMENT ADVISOR. The Fund's investment advisor is Munder Capital
Management, a Delaware general partnership with its principal offices at 480
Pierce Street, Birmingham, Michigan 48009. The principal partners of the
Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM Holdings
II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware corporation
and was a registered investment advisor. WAM and WAM II are Delaware
corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,
1998, the Advisor and its affiliates had approximately $48.2 billion in assets
under management, of which $25.4 billion were invested in equity securities,
$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion
in non-discretionary assets.     
 
  The Advisor provides overall investment management and research and credit
analysis for the Fund and is responsible for all purchases and sales of
portfolio securities for the Fund.
 
  During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate of 0.75% of the average daily net assets of the Fund.
 
  The Advisor may, from time to time, make payments to banks, broker-dealers
or other financial institutions for certain services to the Fund and/or its
shareholders, including sub-administration, sub-transfer agency and
shareholder servicing. The Advisor may make such payments out of its own
resources and there are no additional costs to the Fund or its shareholders.
 
  The Advisor selects broker-dealers to execute portfolio transactions for the
Fund based on best price and execution terms. The Advisor may consider as a
factor the number of shares sold by the broker-dealer.
 
  PERFORMANCE INFORMATION. The table below contains performance information
for the Fund created through the conversion of a common or collective trust
fund which had investment objectives and policies materially equivalent to
those of the Fund. Immediately before and after the conversion, the same
person managed both the common or collective trust fund and the corresponding
Fund.
   
  The table for the Fund:     
     
  . includes the average annual total returns of the common or collective
    trust fund and the average annual total returns of the Fund linked
    together;     
 
  . assumes that net investment income and dividends have been reinvested;
 
  . assumes that the common or collective trust fund paid the same level of
    fees and expenses as the Fund currently pays;
 
                                      11
<PAGE>
 
  . does not reflect any potential negative impact on the common and
    collective trust fund's performance if it had been subjected to the same
    regulatory restrictions (the Investment Company Act of 1940, as amended
    (the "1940 Act") and the Internal Revenue Code of 1986, as amended) as
    the Fund; and
 
  . indicates past performance only and does not predict future results.

reinvestment of dividends. The S&P 500 performance shows total return in U.S.
dollars but does not reflect the deduction of fees, expenses and taxes.     
   
  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Fund's
transfer agent. The Transfer Agent is a wholly owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
01581-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Fund's administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Trust in all aspects of its administration and operations including
overseeing the maintenance of financial records and fund accounting. As
compensation for its services for the Trust, State Street is entitled to
receive fees, based on the aggregate daily net assets of the Fund and certain
other investment portfolios that are advised by the Advisor for which it
provides services, computed daily and payable monthly at the annual rate of
0.113% on the first $2.8 billion of net assets, plus 0.103% on the next $2.2
billion of net assets, plus 0.101% on the next $2.5 billion of net assets,
plus 0.095% on the next $2.5 billion of net assets, plus 0.080% on the next
$2.5 billion of net assets, plus 0.070% on all net assets in excess of $12.5
billion (with a $75,000 minimum fee per annum in the aggregate for all
portfolios with respect to the Administrator).
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Fund. State Street pays the Distributor a fee for
these services out of its own resources at no cost to the Fund.
 
  CUSTODIAN AND SUB-CUSTODIAN. Comerica Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Fund's custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Fund beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Fund. State Street serves as the Fund's sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Fund's shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Fund's shares.
 
  The Fund has adopted a Shareholder Servicing Plan (the "Class K Plan") under
which Class K Shares are sold through institutions which enter into
shareholder servicing agreements with the Fund. The agreements require the
institutions to provide shareholder services to their Customers who from time
to time own of record or beneficially Class K Shares in return for payment by
the Fund at a rate not exceeding .25% (on an annualized basis) of the average
daily net asset value of the Class K Shares beneficially owned by the
Customers. Class K Shares bear all fees paid to institutions under the Class K
Plan. Payments under the Class K Plan are not tied
 
                                      12
<PAGE>
 
exclusively to the shareholder expenses actually incurred by the institutions
and the payments may exceed service expenses actually incurred.
 
  The services provided by institutions under the Class K Plan may include
processing purchase, exchange and redemption requests from Customers and
placing orders with the Transfer Agent; processing dividend and distribution
payments from the Fund on behalf of Customers; providing information
periodically to Customers showing their positions in Class K Shares; providing
sub-accounting with respect to Class K Shares beneficially owned by Customers
or the information necessary for sub-accounting; responding to inquires from
customers concerning their investment in Class K Shares; arranging for bank
wires; and providing such other similar services as may be reasonably
requested.
   
  YEAR 2000. The Fund's operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Fund. The Fund has been informed
that its major service providers have made compliance with the Year 2000 Issue
a high priority and are taking steps that they believe are reasonably designed
to address the Year 2000 Issue with respect to their computer systems. There
can be, however, no assurance that these steps will be successful, or that
interaction with other non-complying computer systems will not impair their
services at that time.     
 
  For an additional description of the services performed by the
Administrator, the Transfer Agent, the Custodian, the Sub-Custodian and the
Distributor, see the SAI.
 
                     WHAT ARE MY RIGHTS AS A SHAREHOLDER?
 
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
the Trust as a whole and affecting the Fund. You will not vote by class unless
expressly required by law or when the Trustees determine the matter to be
voted on affects only the interests of the holders of a particular class of
shares. The Trust will not hold an annual shareholder meeting, but special
meetings may be held at the written request of shareholders owning more than
10% of outstanding shares for the purpose of removing a Trustee. Under
Massachusetts law, it is possible that a shareholder may be personally liable
for the Trust's obligations. If a shareholder were required to pay a debt of
the Fund, however, the Trust has committed to reimburse the shareholder in
full from their assets. The SAI contains more information regarding voting
rights.
 
  Comerica currently has the right to vote a majority of the outstanding
shares of the Fund as agent, custodian or trustee for its customers and
therefore it is considered to be a controlling person of the Trust.
 
                      DIVIDENDS, DISTRIBUTIONS AND TAXES
 
               WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUND?
 
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on the Fund's investments. The Fund passes its earnings along
to investors in the form of dividends. Dividend distributions are the
dividends or interest earned on investments after expenses. The Fund pays
dividends quarterly. The Fund distributes its net realized capital gains
(including net short-term capital gains), if any, at least annually.
 
  It is possible that the Fund may make a distribution in excess of the Fund's
current and accumulated earnings and profits. You will treat such a
distribution as a return of capital which is applied against and reduces your
basis in your shares. You will treat the excess of any such distribution over
your basis in your shares as gain from a sale or exchange of the shares.
 
 
                                      13
<PAGE>
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Fund will pay dividend and capital gains distributions in additional
shares of the same class of the Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Fund at (800) 438-5789.
 
           ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUND?
   
  This section contains a brief summary of the tax implications of ownership
in the Fund's shares. A more detailed discussion about the tax treatment of
distributions from the Fund and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Fund, is contained in the SAI. You should
consult your tax advisor regarding the impact of owning the Fund's shares on
your own personal tax situation including the applicability of any state and
local taxes.     
 
  In general, as long as the Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. The Fund intends to
qualify annually as a RIC. Even if it qualifies as a RIC, the Fund may still
be liable for any excise tax on income that is not distributed in accordance
with a calendar year requirement; the Fund intends to avoid the excise tax by
making timely distributions.
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains derived from sales of portfolio securities held by the Fund
will generally be designated as long-term or short-term. Distributions from
the Fund's long-term capital gains are generally taxed at the long-term
capital gains rate regardless of how long you have owned shares in the Fund.
Dividends from other sources are generally taxed as ordinary income.
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from the Fund a statement
of the amount and nature of the distributions made to you during the year.
 
  If you redeem, transfer or exchange Fund shares, you may have taxable gain
or a loss. If you hold Fund shares for six months or less, and during that
time you receive a capital gain dividend, any loss you realize on the sale of
these Fund shares will be treated as a long-term loss to the extent of the
earlier distribution.
 
  Dividends and certain interest income earned from foreign securities by the
Fund may be subject to foreign withholding or other taxes. The Fund may be
permitted to pass on to its shareholders the right to a credit or deduction
for income or other tax credits earned from foreign investments and intends to
do so if possible. These deductions or credits may be subject to tax law
limitations.
 
  If the Fund invests in certain "passive foreign investment companies"
("PFICs"), it will be subject to Federal income tax (and possibly additional
interest charges) on a portion of any "excess distribution" or gain from the
disposition of such shares, even if it distributes such income to its
shareholders. If the Fund elects to treat a PFIC as a "qualified electing
fund" ("QEF") and the PFIC furnishes certain financial information in the
required form to such Fund, the Fund will instead be required to include in
income each year its allocable share of the ordinary earnings and net capital
gains of the QEF, regardless of whether received, and such amounts will be
subject to the various distribution requirements described above. The Fund may
also elect to mitigate the tax effects of owning PFIC stock by making an
annual mark-to-market election with respect to PFIC shares.

                            ADDITIONAL INFORMATION
 
  SHAREHOLDER COMMUNICATIONS. You will receive unaudited Semi-Annual Reports
and audited Annual Reports on a regular basis from the Fund. In addition, you
will also receive updated Prospectuses or Supplements to this Prospectus. In
order to eliminate duplicate mailings, the Fund will only send one copy of the
above communications to (1) accounts with the same primary record owner, (2)
joint tenant accounts, (3) tenant in common accounts and (4) accounts which
have the same address.

                               FUND INFORMATION
   
  This Prospectus describes Class Y Shares of the Fund. This section
summarizes the Fund's principal investments. The sections entitled "What are
the Fund's Investments and Investment Practices?" and "What are the Risks of
Investing in the Fund?" and the SAI give more information about the Fund's
investment techniques and risks.     
       
  GOALS AND PRINCIPAL INVESTMENTS. The Fund's primary goal is to provide long-
term capital appreciation; its secondary goal is to provide income. Under
normal conditions, the Fund will invest at least 65% of its assets in Equity
Securities.
 
  In choosing Equity Securities, the Advisor considers, among other factors:
 
  . the potential for accelerated earnings growth
 
  . the maintenance of a substantial competitive advantage
 
  . a focused management team
 
  . a stable balance sheet.
 
  PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.
   
  The Fund is closed to new investors.     
 
                      WHO MAY WANT TO INVEST IN THE FUND?
 
  The Fund is designed for investors who desire potentially high capital
appreciation and who can accept short-term variations in return for
potentially greater returns over the long term. In general, the greater the
risk, the greater the potential reward. Investors who have a short time
horizon, who desire a high level of income or who are conservative in their
investment approach may wish to invest in other portfolios offered by the
Trust and the Company.
 
          WHAT ARE THE FUND'S INVESTMENTS AND INVESTMENTS PRACTICES?
   
  The Fund invests in EQUITY SECURITIES, which include common stocks,
preferred stocks, warrants and other securities convertible into common
stocks. Many of the common stocks the Fund will buy will not pay dividends;
instead, stocks will be bought for the potential that their prices will
increase, providing capital appreciation for the Fund. The value of Equity
Securities will fluctuate due to many factors, including the past and
predicted earnings of the issuer, the quality of the issuer's management,
general market conditions, the forecasts for the issuer's industry and the
value of the issuer's assets. Holders of Equity Securities only have rights to
value in the company after all debts have been paid, and they could lose their
entire investment in a company that encounters financial difficulty. Warrants
are rights to purchase securities at a specified time at a specified price.
    
  The Fund may purchase AMERICAN DEPOSITARY RECEIPTS ("ADRS"), EUROPEAN
DEPOSITARY RECEIPTS ("EDRS") and GLOBAL DEPOSITORY RECEIPTS ("GDRS"). ADRs are
issued by U.S. financial institutions and EDRs and GDRs are issued by European
financial institutions. They are receipts evidencing ownership of underlying
Foreign Securities.
 
  The Fund may invest up to 25% of its assets in FOREIGN SECURITIES. Foreign
Securities are securities issued by non-U.S. companies and governments.
Investments in Foreign Securities are riskier than investments in U.S.
companies because (i) foreign companies may be subject to different
accounting, auditing and financial reporting
 
                                       6
<PAGE>
 
standards than U.S. companies, (ii) there is generally less public information
available about foreign companies, (iii) there may be less governmental
regulation and supervision of foreign stock exchanges, securities markets and
companies and (iv) foreign securities may be less liquid and more volatile than
U.S. securities markets.
 
  The Fund may invest in FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS, which are
obligations of the Fund to purchase or sell a specific currency at a future
date at a set price. These contracts may decrease the Fund's loss due to a
change in currency value, but also limits gains from currency exchanges.
 
  The Fund may invest in FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.
Futures contracts are contracts in which the Fund agrees, at maturity, to make
delivery of or receive securities, the cash value of an index or foreign
currency. Futures contracts and options on futures contracts are used for
hedging purposes or to maintain liquidity. The Fund may not purchase or sell a
futures contract unless immediately after any such transaction the sum of the
aggregate amount of margin deposits on its existing futures positions and the
amount of premiums paid for related options is 5% or less of its total assets.
The Fund will set aside cash or other liquid securities to "cover" the Fund's
position in futures.
 
  The Fund may purchase or sell OPTIONS. The Fund may buy options giving it the
right to require a buyer to buy a security held by the Fund (put options), buy
options giving it the right to require a seller to sell securities to the Fund
(call options), sell (write) options giving a buyer the right to require the
Fund to buy securities from the buyer or write options giving a buyer the right
to require the Fund to sell securities to the buyer during a set time at a set
price. Options may relate to stock indices, individual securities, foreign
currencies or futures contracts. See the SAI for more details and additional
limitations.
 
  The Fund may purchase securities on a "WHEN-ISSUED" basis and may purchase or
sell securities on a "FORWARD COMMITMENT" basis. Although the price to be paid
by the Fund is set at the time of the agreement, the Fund usually does not pay
for the securities until they are received. The value of securities may change
between the time the price is set and payment. When the Fund purchases
securities for future delivery, the Fund's custodian will set aside cash or
liquid securities to "cover" the Fund's position. The Fund does not intend to
purchase securities for future delivery for speculative purposes.
 
  The Fund may enter into REPURCHASE AGREEMENTS. Under a repurchase agreement,
the Fund agrees to purchase securities from a seller and the seller agrees to
repurchase the securities at a later time, typically within seven days, at a
set price. The seller agrees to set aside collateral at least equal to the
repurchase price. This ensures that the Fund will receive the purchase price at
the time it is due, unless the seller defaults or declares bankruptcy, in which
event the Fund will bear the risk of possible loss due to adverse market action
or delays in liquidating the underlying obligation.
 
  The Fund may invest in REVERSE REPURCHASE AGREEMENTS. Under a reverse
repurchase agreement, the Fund sells securities and agrees to buy them back
later at an agreed upon time and price. Reverse repurchase agreements are used
to borrow money for temporary purposes.
 
  The Fund may LEND SECURITIES to broker-dealers and other financially sound
institutional investors who will pay the Fund for the use of the securities,
thus potentially increasing the Fund's returns. The borrower must set aside
cash or liquid securities equal to the value of the securities borrowed at all
times during the terms of the loan. Loans may not exceed 25% of the value of
the Fund's total assets. Risks involved in such transactions include possible
delay in recovering the loaned securities and possible loss of the securities
or the collateral if the borrower fails financially.
 
  The Fund may buy shares of registered MONEY MARKET FUNDS. The Fund will bear
a portion of the expenses of any investment company whose shares they purchase,
including operating costs and investment advisory, distribution and
administration fees. These expenses would be in addition to the Fund's own
expenses. The Fund may invest up to 10% of its assets in other investment
companies and no more than 5% of its assets in any one investment company.

  The Fund may invest in CASH EQUIVALENTS, which are high-quality, short-term
money market instruments including, among other things, commercial paper,
bankers' acceptances and negotiable certificates of deposit of banks or savings
and loan associations, short-term corporate obligations and short-term
securities issued by, or guaranteed by, the U.S. Government and its agencies or
instrumentalities. These instruments will be used primarily pending investment,
to meet anticipated redemptions or as a temporary defensive measure. If the
Fund is investing defensively, it may not be pursuing its investment objective.
    
  The Fund may purchase FIXED INCOME SECURITIES. Fixed Income Securities are
securities which either pay interest at set times at either fixed or variable
rates, or which realize a discount upon maturity. Fixed Income Securities
include corporate bonds, debentures, notes and other similar corporate debt
instruments, zero coupon bonds (discount debt obligations that do not make
interest payments) and variable amount master demand notes that permit the
amount of indebtedness to vary in addition to providing for periodic
adjustments in the interest rate. The Fund may purchase U.S. GOVERNMENT
SECURITIES, which are securities issued by, or guaranteed by, the U.S.
Government or its agencies or instrumentalities. Such securities include U.S.
Treasury bills, which have initial maturities of less than one year, U.S.
Treasury notes, which have initial maturities of one to ten years, U.S.
Treasury bonds, which generally have initial maturities of greater than ten
years, and obligations of the Federal Home Loan Mortgage Corporation, Federal
National Mortgage Association and Government National Mortgage Association.
Under normal market conditions, the Fund will not invest to a significant
extent, or on a routine basis, in U.S. Government Securities.
 
  The Fund may invest up to 5% of its total assets in LOWER-RATED DEBT
SECURITIES. Lower-Rated Debt Securities are securities that are rated below
investment grade by Standard & Poor's Rating Service, Moody's Investors
Service, Inc. or other nationally recognized rating agency. Such securities are
also known as "junk bonds" and are considered riskier than investment grade
securities.
 
  The Fund may invest up to 15% of the value of its net assets in ILLIQUID
SECURITIES. Illiquid Securities are securities for which there is no ready
market, which inhibits the ability to sell them and obtain their full market
value, or which are legally restricted as to their resale by the Fund.
 
  The Fund may BORROW MONEY in an amount up to 5% of its assets for temporary
purposes and in an amount up to 33 1/3% of its assets to meet redemptions. This
is a "fundamental" policy which can be changed only by shareholders.
 
  The Fund is classified as a "diversified fund." With respect to 75% of a
diversified Fund's assets, a diversified Fund cannot invest more than 5% of its
assets in a single issuer (other than U.S. Government and its agencies and
instrumentalities). In addition, a diversified Fund cannot invest more than 25%
of its assets in a single issuer.
 
                  WHAT ARE THE RISKS OF INVESTING IN THE FUND?
 
  Investing in the Fund may be less risky than investing in individual stocks
due to the diversification of investing in a portfolio of many different
stocks; however, such diversification does not eliminate all risks. Because the
Fund invests mostly in Equity Securities, rises and falls in the stock market
in general, as well as in the value of particular Equity Securities held by the
Fund, can affect the Fund's performance. Your investment in the Fund is not
guaranteed. The net asset value of the Fund will change daily and you might not
recoup the amount you invest in the Fund.
 
  Consistent with a long-term investment approach, investors in the Fund should
be prepared and able to maintain their investments during periods of adverse
market conditions. By itself, the Fund is a balanced investment program and
there is no guarantee that the Fund will achieve its investment objective since
there is uncertainty in every investment.
 
  A Fund's risk is mostly dependent on the types of securities it purchases and
its investment techniques. The Fund is authorized to use options, futures, and
forward foreign currency exchange contracts, which are types of derivative
instruments. Derivative instruments are instruments that derive their value
from a different underlying
 
                                       8
<PAGE>
 
security, index or financial indicator. The use of derivative instruments
exposes the Fund to additional risks and transaction costs. Risks inherent in
the use of derivative instruments include: (1) the risk that interest rates,
securities prices and currency markets will not move in the direction that a
portfolio manager anticipates; (2) imperfect correlation between the price of
derivative instruments and movements in the prices of the securities, interest
rates or currencies being hedged; (3) the fact that skills needed to use these
strategies are different than those needed to select equity securities; (4) the
possible absence of a liquid secondary market for any particular instrument and
possible exchange imposed price fluctuation limits, either of which may make it
difficult or impossible to close out a position when desired; (5) leverage
risk, that is, the risk that adverse price movements in an instrument can
result in a loss substantially greater than the Fund's initial investment in
that instrument (in some cases, the potential loss is unlimited); (6)
particularly in the case of privately-negotiated instruments, the risk that the
counterparty will not perform its obligations, which could leave the Fund worse
off than if it had not entered into the position and (7) inability to close out
certain hedged positions to avoid adverse tax consequences.
 
  To the extent that the Fund invests in illiquid securities, the Fund risks
not being able to sell securities at the time and the price that it would like.
The Fund may therefore have to lower the price, sell substitute securities or
forego an investment opportunity, each of which might adversely affect the
Fund.
 
  The risks of the various investment techniques the Fund uses are described in
more detail in the SAI.
 
                                  PERFORMANCE
 
                   HOW IS THE FUND'S PERFORMANCE CALCULATED?
 
  There are various ways in which the Fund may calculate and report its
performance. Performance is calculated separately for each class of shares.
 
  One method is to show the Fund's total return. Cumulative total return is the
percentage change in the value of an amount invested in a class of shares of
the Fund over a stated period of time and takes into account reinvested
dividends. Cumulative total return most closely reflects the actual performance
of the Fund.
 
  Average annual total return refers to the average annual compounded rates of
return over a specified period on an investment in shares of the Fund
determined by comparing the initial amount invested to the ending redeemable
value of the amount, taking into account reinvested dividends.
 
  The Fund may also publish its current yield. Yield is the net investment
income generated by a share of the Fund during a 30-day period divided by the
maximum offering price on the 30th day.
 
  You should be aware that (i) past performance does not indicate how the Fund
will perform in the future; and (ii) the Fund's return and net asset value will
fluctuate, so you cannot necessarily use the Fund's performance data to compare
it to investment in certificates of deposit, savings accounts or other
investments that provide a fixed or guaranteed yield.
 
  The Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. The Fund may also compare its total return
to broad-based indices. These indices show the value of selected portfolios of
securities (assuming reinvestment of interest and dividends) which are not
managed by a portfolio manager. The Fund may report how it is performing in
comparison to the Consumer Price Index, an indication of inflation reported by
the U.S. Government.

                     WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Fund's annual report dated June 30 of each year and semi-
annual report dated December 31 of each year, which will automatically be
mailed to shareholders. To obtain copies of financial reports or performance
information, call (800) 438-5789.
 
                       PURCHASES AND EXCHANGES OF SHARES
 
  The following persons may purchase Class Y Shares:
     
  . fiduciary and discretionary accounts of institutions;     
     
  . institutional investors (including banks, savings institutions, credit
    unions and other financial institutions, pension, profit sharing and
    employee benefit plans and trusts, insurance companies, investment
    companies, investment advisors and broker-dealers acting either for their
    own accounts or for the accounts of institutional investors);     
     
  . directors, trustees, officers and employees of the Trust, the Company,
    Framlington, the Advisor and the Distributor;     
     
  . the Advisor's investment advisory clients; and     
     
  . family members of employees of the Advisor.     
 
  The Fund also issues other classes of shares, which have different sales
charges, expense levels and performance. Call (800) 438-5789 to obtain more
information concerning the Fund's other classes of shares.
 
                        WHAT PRICE DO I PAY FOR SHARES?
 
  The purchase price for Class Y Shares is the net asset value ("NAV") next
determined after we receive your order in proper form. You should be aware
that broker-dealers (other than the Fund's Distributor) may charge investors
additional fees if shares are purchased through them.
   
  Except in certain limited circumstances, the Fund determines its NAV on each
day the New York Stock Exchange ("NYSE") is open for trading (a "Business
Day") at the close of such trading on the NYSE (normally 4:00 p.m. Eastern
time). The Fund calculates NAV separately for each class of shares. NAV is
calculated by totaling the value of all of the assets of the Fund allocated to
a particular class of shares, subtracting the Fund's liabilities and expenses
charged to that class and dividing the result by the number of shares of that
class outstanding.     
 
                          WHEN CAN I PURCHASE SHARES?
 
  Shares of the Fund are sold on a continuous basis and can be purchased on
any Business Day.
 
                   WHAT IS THE MINIMUM REQUIRED INVESTMENT?
 
  The minimum initial investment by fiduciary and discretionary accounts of
institutions and institutional investors for Class Y Shares is $500,000. Other
types of investors are not subject to any minimum required investment.
 
                          HOW CAN I PURCHASE SHARES?
 
  You can purchase Class Y Shares in a number of different ways. You may place
orders for Class Y Shares directly through the Transfer Agent or the
Distributor or through arrangements with a financial institution.

    financial institution through procedures established with that
    institution. Confirmations of share purchases will be sent to the
    institution.

                            Account No.:
 
   Note that banks may charge fees for transmitting wires.
 
  . AUTOMATIC INVESTMENT PLAN ("AIP"). Under the AIP you may arrange for
    periodic investments in the Fund through automatic deductions from a
    checking or savings account. To enroll in the AIP you should complete the
    AIP Application Form or call the Fund at (800) 438-5789. The minimum pre-
    authorized investment amount is $50. You may discontinue the AIP at any
    time. We may discontinue the AIP on 30 days' written notice to you.
 
  The Transfer Agent will send you confirmations of the opening of an account
and of all subsequent purchases, exchanges or redemptions in the account. If
your account has been set up by a broker or other investment professional,
account activity will be detailed in their statements to you.
   
  We do not issue share certificates. We reserve the right to (i) reject any
purchase order if, in our opinion, it is in the Fund's best interest to do so
and (ii) suspend the offering of shares of any class for any period of time.
You may pay for shares of the Fund, with securities which the Fund is allowed
to hold.     
 
  See the SAI for further information regarding purchases of the Fund's shares.
 
                           HOW CAN I EXCHANGE SHARES?
 
  You may exchange Class Y Shares of the Fund for Class Y Shares of other funds
of the Trust, the Company or Framlington based on their relative net asset
values.
 
  You must meet the minimum purchase requirements for the fund of the Trust,
the Company or Framlington that you purchase by exchange. Please note that a
share exchange may be a taxable event and accordingly, you may realize a
taxable gain or loss. Before making an exchange request, read the Prospectus of
the fund you wish to purchase by exchange. You can obtain a Prospectus for any
fund of the Trust, the Company or Framlington by contacting your broker or the
Fund at (800) 438-5789. Brokers may charge a fee for handling exchanges.
 
  We may modify or terminate the exchange privilege at any time. You will be
given notice of any material modifications except where notice is not required.
 
                             REDEMPTIONS OF SHARES
 
                  WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?
 
  The redemption price is the NAV next determined after we receive the
redemption request in proper form.
 
 
                                       11
<PAGE>
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. The Fund may temporarily stop
redeeming shares when the NYSE is closed or trading on the NYSE is restricted,
when an emergency exists and the Fund cannot sell its assets or accurately
determine the value of its assets or if the SEC orders the Fund to suspend
redemptions.
 
                            HOW CAN I REDEEM SHARES?
   
  Redemption orders are effected at the NAV next determined after receipt of
the order by the Transfer Agent. Shares held by an institution on behalf of its
Customers must be redeemed in accordance with instructions and limitations
pertaining to the account at that institution.     
 
  . INVOLUNTARY REDEMPTION. We may redeem your account if its value falls
    below $250 as a result of redemptions (but not as a result of a decline
    in NAV). You will be notified in writing and allowed 60 days to increase
    the value of your account to the minimum investment level.
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  If we receive a redemption order for the Fund before 4:00 p.m. (Eastern time)
on a Business Day, we will normally wire payment to the redeeming institution
on the next Business Day. We may delay wiring redemption proceeds for up to
seven days if we feel an earlier payment would have a negative impact on the
Fund.
 
                      STRUCTURE AND MANAGEMENT OF THE FUND
 
                          HOW IS THE FUND STRUCTURED?
 
  The Trust is an open-end management investment company, which is a mutual
fund that sells and redeems shares every day that it is open for business. It
is managed under the direction of its governing Board of Trustees, which is
responsible for the overall management of the Trust and supervise the Fund's
service providers. The Trust is organized as a Massachusetts business trust.
 
                       WHO MANAGES AND SERVICES THE FUND?
   
  INVESTMENT ADVISOR. The Fund's investment advisor is Munder Capital
Management, a Delaware general partnership with its principal offices at 480
Pierce Street, Birmingham, Michigan 48009. The principal partners of the
Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM Holdings
II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware corporation
and was a registered investment advisor. WAM and WAM II are Delaware
corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,
1998, the Advisor and its affiliates had approximately $48.2 billion in assets
under management, of which $25.4 billion were invested in equity securities,
$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion in
non-discretionary assets.     
 
  The Advisor provides overall investment management and research and credit
analysis for the Fund and is responsible for all purchases and sales of
portfolio securities for the Fund.
 
  During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate of 0.75% of the average daily net assets of the Fund
(after waivers, if any).
 
  The Advisor may, from time to time, make payments to banks, broker-dealers or
other financial institutions for certain services to the Fund and/or their
shareholders, including sub-administration, sub-transfer agency and shareholder
servicing. The Advisor may make such payments out of its own resources and
there are no additional costs to the Fund or its shareholders.
 
 
                                       12
<PAGE>
 
  The Advisor selects broker-dealers to execute portfolio transactions for the
Fund based on best price and execution terms. The Advisor may consider as a
factor the number of shares sold by the broker-dealer.
 
  PERFORMANCE INFORMATION. The table below contains performance information
for the Fund created through the conversion of a common or collective trust
fund which had investment objectives and policies materially equivalent to
those of the Fund. Immediately before and after the conversion, the same
person managed both the common or collective trust fund and the Fund.
 
  The table for the Fund:
 
  . includes the average annual total returns of the common or collective
    trust fund and the average annual total returns of the Fund linked
    together;
 
  . assumes that net investment income and dividends have been reinvested;
 
  . assumes that the common or collective trust fund paid the same level of
    fees and expenses as the Fund currently pays;
 
  . does not reflect any potential negative impact on the common and
    collective trust fund's performance if it had been subjected to the same
    regulatory restrictions (the Investment Company Act of 1940, as amended
    (the "1940 Act") and the Internal Revenue Code of 1986, as amended) as
    the Fund; and
 
  . indicates past performance only and does not predict future results.

  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Fund's
transfer agent. The Transfer Agent is a wholly-owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
01581-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Fund's administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Trust in all aspects of its administration and operations including
overseeing the maintenance of financial records and fund accounting. As
compensation for its services for the Trust, State Street is entitled to
receive fees, based on the aggregate daily net assets of the Fund and certain
other investment portfolios that are advised by the Advisor for which it
provides services, computed daily and payable monthly at the annual rate of
0.113% on the first $2.8 billion of net assets, plus 0.103% on the next $2.2
billion of net assets, plus 0.101% on the next $2.5 billion of net assets,
plus 0.095% on the next $2.5 billion of net assets, plus 0.080% on the next
$2.5 billion of net assets, plus 0.070% on all net assets in excess of $12.5
billion (with a $75,000 minimum fee per annum in the aggregate for all
portfolios with respect to the Administrator).
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Fund. State Street pays the Distributor a fee for
these services out of its own resources at no cost to the Fund.
 
 
                                      13
<PAGE>
 
  CUSTODIAN AND SUB-CUSTODIAN. Comerica Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Fund's custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Fund beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Fund. State Street serves as the Fund's sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Fund's shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Fund's shares.
 
  For an additional description of the services performed by the
Administrator, the Transfer Agent, the Custodian, the Sub-Custodian and the
Distributor, see the SAI.
   
  YEAR 2000. The Fund's operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Fund. The Fund has been informed
that its major service providers have made compliance with the Year 2000 Issue
a high priority and are taking steps that they believe are reasonably designed
to address the Year 2000 Issue with respect to their computer systems. There
can be, however, no assurance that these steps will be successful, or that
interaction with other non-complying computer systems will not impair their
services at that time.     
 
                     WHAT ARE MY RIGHTS AS A SHAREHOLDER?
 
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
the Trust as a whole and affecting the Fund. You will not vote by class unless
expressly required by law or when the Trustees determine the matter to be
voted on affects only the interests of the holders of a particular class of
shares. The Trust will not hold an annual shareholder meeting, but special
meetings may be held at the written request of shareholders owning more than
10% of outstanding shares for the purpose of removing a Trustee. Under
Massachusetts law, it is possible that a shareholder may be personally liable
for the Trust's obligations. If a shareholder were required to pay a debt of
the Fund, however, the Trust has committed to reimburse the shareholder in
full from their assets. The SAI contains more information regarding voting
rights.
 
  Comerica currently has the right to vote a majority of the outstanding
shares of the Fund as agent, custodian or trustee for its customers and
therefore it is considered to be a controlling person of the Trust.
 
                      DIVIDENDS, DISTRIBUTIONS AND TAXES
 
               WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUND?
 
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on the Fund's investments. The Fund passes its earnings along
to investors in the form of dividends. Dividend distributions are the
dividends or interest earned on investments after expenses. The Fund pays
dividends quarterly. The Fund distributes its net realized capital gains
(including net short-term capital gains), if any, at least annually.
 
  It is possible that the Fund may make a distribution in excess of the Fund's
current and accumulated earnings and profits. You will treat such a
distribution as a return of capital which is applied against and reduces your
basis in your shares. You will treat the excess of any such distribution over
your basis in your shares as gain from a sale or exchange of the shares.

<PAGE>
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Fund will pay dividend and capital gains distributions in additional
shares of the same class of the Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Fund at (800) 438-5789.
 
           ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUND?
   
  This section contains a brief summary of the tax implications of ownership in
the Fund's shares. A more detailed discussion about the tax treatment of
distributions from the Fund and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Fund, is contained in the SAI. You should consult
your tax advisor regarding the impact of owning the Fund's shares on your own
personal tax situation including the applicability of any state and local
taxes.     
 
  In general, as long as the Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. The Fund intends to qualify
annually as a RIC. Even if it qualifies as a RIC, the Fund may still be liable
for any excise tax on income that is not distributed in accordance with a
calendar year requirement; the Fund intends to avoid the excise tax by making
timely distributions.
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains derived from sales of portfolio securities held by the Fund
will generally be designated as long-term or short-term. Distributions from the
Fund's long-term capital gains are generally taxed at the long-term capital
gains rate regardless of how long you have owned shares in the Fund. Dividends
from other sources are generally taxed as ordinary income.
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from the Fund a statement
of the amount and nature of the distributions made to you during the year.
 
  If you redeem, transfer or exchange Fund shares, you may have taxable gain or
a loss. If you hold Fund shares for six months or less, and during that time
you receive a capital gain dividend, any loss you realize on the sale of these
Fund shares will be treated as a long-term loss to the extent of the earlier
distribution.
 
  Dividends and certain interest income earned from foreign securities by the
Fund may be subject to foreign withholding or other taxes. The Fund may be
permitted to pass on to its shareholders the right to a credit or deduction for
income or other tax credits earned from foreign investments and intends to do
so if possible. These deductions or credits may be subject to tax law
limitations.
 
  If the Fund invests in certain "passive foreign investment companies"
("PFICs"), it will be subject to Federal income tax (and possibly additional
interest charges) on a portion of any "excess distribution" or gain from the
disposition of such shares, even if it distributes such income to its
shareholders. If the Fund elects to treat a PFIC as a "qualified electing fund"
("QEF") and the PFIC furnishes certain financial information in the required
form to such Fund, the Fund will instead be required to include in income each
year its allocable share of the ordinary earnings and net capital gains of the
QEF, regardless of whether received, and such amounts will be subject to the
various distribution requirements described above. The Fund may also elect to
mitigate the tax effects of owning PFIC stock by making an annual mark-to-
market election with respect to PFIC shares.

                                FUND HIGHLIGHTS
 
                  WHAT ARE THE KEY FACTS REGARDING THE FUNDS?
 
Q: What are the Funds' goals?
 
A:
 . The Bond Fund seeks to provide a high level of current income with capital
   appreciation as a secondary consideration.
 
 . The Intermediate Bond Fund seeks to provide a competitive rate of return
   which exceeds the inflation rate and the return provided by money market
   instruments.
 
 . The International Bond Fund seeks to provide a competitive total return
   through a combination of current income and capital appreciation.
 
 . The U.S. Government Income Fund seeks to provide high current income.
 
 . The Tax-Free Intermediate Bond Fund and Tax-Free Bond Fund seek to provide
   current interest income exempt from Federal income taxes.
    
 . The Michigan Tax-Free Bond Fund seeks to provide as high a level of
   current interest income exempt from regular Federal income taxes and
   Michigan state income tax as is consistent with prudent investment
   management and preservation of capital.     
 
Q: What are the Funds' strategies?
 
A:
    
 . The Funds, other than the Michigan Tax-Free Bond Fund, the Tax-Free Bond
   Fund and the Tax-Free Intermediate Bond Fund (together, the "Tax-Free
   Funds"), and the U.S. Government Income Fund, invest primarily in Fixed
   Income Securities. "Fixed Income Securities" are securities which either
   pay interest at set times at either fixed or variable rates, or which
   realize a discount upon maturity. Fixed Income Securities include
   corporate bonds, debentures, notes and other similar corporate debt
   instruments, zero coupon bonds (discount debt obligations that do not make
   interest payments) and variable amount master demand notes that permit the
   amount of indebtedness to vary in addition to providing for periodic
   adjustments in the interest rates.     
 
 . The U.S. Government Income Fund invests primarily in obligations of the
   U.S. government and its agencies and instrumentalities.
 
 . The Tax-Free Bond Fund and Tax-Free Intermediate Bond Fund invest
   primarily in Municipal Obligations. "Municipal Obligations" are
   obligations of states, territories and possessions of the United States
   and the District of Columbia and their political subdivisions, agencies,
   instrumentalities and authorities, the interest on which is exempt from
   regular Federal income tax.
    
 . The Michigan Tax-Free Bond Fund invests primarily in Michigan Municipal
   Obligations. "Michigan Municipal Obligations" are municipal obligations
   issued by the State of Michigan and its political subdivisions, the
   interest on which is exempt from Federal income taxes and Michigan state
   income tax.

Q: What are the Funds' risks?
 
A: The following table summarizes the primary risks of investing in the Funds:
 
<TABLE>   
<CAPTION>
                FUND                                   RISK
  -----------------------------------------------------------------------------
   <C>                             <S>
   All Funds                       Potential loss of investment due to changes
                                   in the bond market in general, in the prices
                                   of debt securities of particular companies
                                   and in interest rates.
  -----------------------------------------------------------------------------
   International Bond Fund         Because of large investments in foreign
                                   securities, the Fund is riskier than
                                   domestic funds due to factors such as
                                   freezes on convertibility of currency,
                                   changes in exchange rates, political
                                   instability and differences in accounting
                                   and reporting standards.
  -----------------------------------------------------------------------------
   International Bond Fund,        These "non-diversified" Funds concentrate
   Michigan Tax-Free Bond Fund and their investments in fewer issuers than
   Tax-Free Intermediate Bond Fund diversified funds, and could experience
                                   larger price fluctuations than diversified
                                   funds.
</TABLE>    
 
 
Q: What are the options for investment in the Funds?
 
A: Each Fund offers five different investment options, or classes: Class A, B,
C, K and Y. Class K and Y Shares, which are only offered to institutional and
other qualified investors, are offered in other prospectuses.

*  An annual fee for distributing shares and servicing shareholder accounts
   paid based on the Fund's average daily net assets.
** A one-time fee charged at the time of purchase of shares. The fee declines
   based on the amount you invest.
*** A contingent deferred sales charge ("CDSC") is a one-time fee charged at
    the time of redemption. The fee declines based on the length of time you
    hold the shares.
+  A CDSC of 1% is imposed on certain redemptions of Class A Shares if
   redeemed within one year of purchase.
 
  (i) If you invest over $250,000, you must buy Class A or Class C Shares.
(ii) Class B Shares convert automatically to Class A Shares after six years.
Due to the level of Rule 12b-1 fees and the CDSC on Class B Shares versus
Class A or Class C Shares, both (i) and (ii) are to your economic benefit.
 
Q: How do I buy and sell shares of the Funds?
 
A: Funds Distributor, Inc. (the "Distributor") sells shares of the Funds. You
may purchase shares from the Distributor through broker-dealers or other
financial institutions or from the Funds' transfer agent, First Data Investor
Services Group, Inc. ("Transfer Agent"), by mailing the attached Account
Application Form with a check to the Transfer Agent. You must invest at least
$250 ($50 through the Automatic Investment Plan) initially and at least $50
for subsequent purchases.
 
  Shares may be redeemed (sold back to the Fund) by mail or by telephone.
 
  You may also acquire the Funds' shares by exchanging shares of the same
class of other funds of the Trust, the Company and The Munder Framlington
Funds Trust ("Framlington"), and exchange Fund shares for shares of the same
class of other funds of the Trust, the Company and Framlington.

  The purpose of this table is to assist you in understanding the expenses
charged directly to each Fund, which investors in the Funds will bear
indirectly for the current fiscal year. Such expenses include payments to
Trustees, Directors, auditors, legal counsel and service providers (such as
the Advisor), registration fees and distribution fees. The expenses shown
below are based on expenses for the Funds' past fiscal year. Because of the
12b-1 fee, you may over the long term pay more than the amount of the maximum
permitted front-end sales charge.

                     WHO MAY WANT TO INVEST IN THE FUNDS?
 
  The Funds are designed for investors who desire potentially higher returns
than more conservative fixed rate investments or money market funds and who
seek current income. The Tax-Free Funds may be desirable for investors who
seek primarily tax-exempt income. When you choose among the Funds, you should
consider both the expected yield of the Funds and potential changes in each
Fund's share price. The yield and potential price changes of a Fund's shares
depend on the quality and maturity of the obligations in its portfolio, as
well as on other market conditions.
 
           WHAT ARE THE FUNDS' INVESTMENTS AND INVESTMENT PRACTICES?
   
  All of the Funds, other than the International Bond Fund, the Michigan Tax-
Free Bond Fund and the Tax-Free Intermediate Bond Fund, are classified as
"diversified funds." With respect to 75% of each diversified Fund's assets,
each diversified fund cannot invest more than 5% of its assets in one issuer
(other than the U.S. Government and its agencies and instrumentalities). In
addition, each diversified fund cannot invest more than 25% of its assets in a
single issuer. These restrictions do not apply to the non-diversified funds.
    
  The Tax-Free Funds will acquire long-term instruments only which are rated A
or better by Moody's Investors Service Inc. ("Moody's") or Standard & Poor's
Rating Service ("S&P") or, if unrated, are of comparable quality. These Funds
will acquire short-term instruments only which (i) have short-term debt
ratings in the top two categories by at least one nationally recognized
statistical rating organization, (ii) are issued by an issuer with such
ratings or (iii), if unrated, are of comparable quality.
   
  The Advisor does not intend to invest more than 25% of a Fund's assets in
securities whose issuers are in the same state, except that the Advisor may
invest more than 25% of the Michigan Tax-Free Bond Fund's and the Tax-Free
Intermediate Bond Fund's assets in Michigan Municipal Obligations.     
 
  Each Tax-Free Fund may invest in short term money market instruments on a
temporary basis or for temporary investment purposes. Short term money market
instruments include U.S. government obligations, debt securities of issuers
having a rating within the two highest categories of either S&P or Moody's,
and certificates of deposit or bankers' acceptances of domestic branches of
U.S. banks with at least $1 billion in assets.

                 WHAT ARE THE RISKS OF INVESTING IN THE FUNDS?
 
  The value of each Fund's shares, like the value of most securities, will
rise and fall in response to changes in economic conditions, interest rates
and the market's perception of the underlying securities held by the Fund.
Investing in the Funds may be less risky than investing in individual Fixed
Income Securities due to the diversification of investing in a portfolio
containing many different Fixed Income Securities; however, such diversity
does not eliminate all risks. The Funds invest mostly in Fixed Income
Securities, whose values typically rise when interest rates fall and fall when
interest rates rise. Fixed Income Securities with shorter maturities (time
period until repayment) tend to be less affected by interest rate changes, but
generally offer lower yields than securities with longer maturities. Current
yield levels should not be considered representative of yields for any future
time. Securities with variable interest rates may exhibit greater price
variations than ordinary securities. Zero coupon bonds are subject to greater
market fluctuations from changing interest rates than debt obligations of
comparable maturities which make current distributions of interest.
 
  Consistent with a long-term investment approach, investors in a Fund should
be prepared and able to maintain their investments during periods of adverse
market conditions. By itself, no Fund is a balanced investment program and
there is no guarantee that any Fund will achieve its investment objective
since there is uncertainty in every investment.
 
  A Fund's risk is mostly dependent on the types of securities it purchases
and its investment techniques. Some Funds are authorized to use options,
futures, currency swaps, interest rate swaps and/or forward foreign currency
exchange contracts, which are types of derivative instruments. Derivative
instruments are instruments that derive their value from a different
underlying security, index or financial indicator. The use of derivative
instruments exposes a Fund to additional risks and transaction costs. Risks
inherent in the use of derivative instruments include: (1) the risk that
interest rates, securities prices and currency markets will not move in the
direction that a portfolio manager anticipates; (2) imperfect correlation
between the price of derivative instruments and movements in the prices of the
securities, interest rates or currencies being hedged; (3) the fact that
skills needed to use these strategies are different than those needed to
select portfolio securities; (4) inability to close out certain hedged
positions to avoid adverse tax consequences; (5) the possible absence of a
liquid secondary market for any particular instrument and possible exchange-
imposed price fluctuation limits, either of which may make it difficult or
impossible to close out a position when desired; (6) leverage risk, that is,
the risk that adverse price movements in an instrument can result in a loss
substantially greater than the Fund's initial investment in that instrument
(in some cases, the potential loss is unlimited); and (7) particularly in the
case of privately-negotiated instruments, the risk that the counterparty will
not perform its obligations, which could leave the Fund worse off than if it
had not entered into the position.
   
 International Bond Fund, Michigan Tax-Free Bond Fund and Tax-Free
Intermediate Bond Fund     
   
  These Funds are non-diversified and hold securities of a limited number of
issuers. The Funds may, therefore, pose a greater risk to investors than an
investment in a diversified fund. The Michigan Tax-Free Bond Fund invests
primarily in Michigan Municipal Securities. If Michigan issuers suffer serious
financial difficulties jeopardizing their ability to pay their obligations,
the net asset value of such Fund may decline.     
 
  Investing in the International Bond Fund, with its larger investment in
Foreign Securities, may involve more risk than investing in a U.S. fund for
the following reasons: (1) there may be less public information available
about foreign companies than is available about U.S. companies; (2) foreign
companies are not generally subject to the uniform accounting, auditing and
financial reporting standards and practices applicable to U.S. companies; (3)
foreign markets have less volume than the U.S. market, and the securities of
some foreign companies are less liquid and more volatile than the securities
of comparable U.S. companies; (4) there may be less government regulation of
exchanges, brokers, listed companies and banks in foreign countries than in
the United States; (5) the Fund may incur fees on currency exchanges when it
changes investments from one country to another; (6) the Fund's foreign
investments could be affected by expropriation, confiscatory taxation,
nationalization of bank deposits, establishment of exchange controls,
political or social instability or diplomatic developments; (7)
 
                                      30
<PAGE>
 
fluctuations in foreign exchange rates will affect the value of the Fund's
portfolio securities, the value of dividends and interest earned, gains and
losses realized on the sale of securities, net investment income and unrealized
appreciation or depreciation of investments; and (8) the possible imposition of
dividend or interest withholding by a foreign country.
 
  The risks of the various investment techniques the Funds use are described in
more detail in the SAI.
 
                                  PERFORMANCE
 
                   HOW IS THE FUNDS' PERFORMANCE CALCULATED?
 
  There are various ways in which the Funds may calculate and report their
performance. Performance is calculated separately for each class of shares.
 
  One method is to show a Fund's total return. Cumulative total return is the
percentage change in the value of an amount invested in a class of shares of a
Fund over a stated period of time and takes into account reinvested dividends
plus in the case of Class A Shares, the payment of the maximum sales charge
and, in the case of Class B and Class C Shares, the maximum CDSC. Cumulative
total return most closely reflects the actual performance of a Fund. However, a
shareholder who opts to receive dividends in cash, a Class A shareholder who
paid a sales charge lower than 4.0%, or a Class B or C shareholder who paid
lower than the maximum CDSC will have a different return than the reported
performance.
 
  Average annual total return refers to the average annual compounded rates of
return over a specified period on an investment in shares of a Fund determined
by comparing the initial amount invested to the ending redeemable value of the
amount, taking into account reinvested dividends, the payment of the maximum
sales charge on Class A Shares, and the payment of the maximum CDSC on Class B
and Class C Shares.
 
  Each Fund may also publish its current yield. Yield is the net investment
income generated by a share of a Fund during a 30-day period divided by the
maximum offering price on the 30th day. "Maximum offering price" includes the
sales charge for Class A Shares.
 
  The Funds may sometimes publish total returns that do not take into account
sales charges and such returns will be higher than returns which include sales
charges. You should be aware that (i) past performance does not indicate how a
Fund will perform in the future and (ii) each Fund's return and net asset value
will fluctuate, so you cannot necessarily use a Fund's performance data to
compare it to investment in certificates of deposit, savings accounts or other
investments that provide a fixed or guaranteed yield.
 
  Each Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. Each Fund may also compare its total return
to broad-based indices. These indices show the value of selected portfolios of
securities (assuming reinvestment of interest and dividends) which are not
managed by a portfolio manager. The Funds may report how they are performing in
comparison to the Consumer Price Index, an indication of inflation reported by
the U.S. Government.
 
                      WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Funds' annual report dated June 30 of each year and semi-
annual report dated December 31 of each year, which will automatically be
mailed to shareholders. To obtain copies of financial reports or performance
information, call (800) 438-5789.

                       PURCHASES AND EXCHANGES OF SHARES
 
             WHICH SHARE CLASS SHOULD I CHOOSE FOR MY INVESTMENT?
 
  Each of the Funds offers Class A, Class B and Class C Shares. Each Class has
its own cost structure, allowing you to choose the one that best meets your
requirements given the amount of your purchase and the intended length of your
investment. You should consider both ongoing annual expenses and initial or
contingent deferred sales charges in estimating the costs of investing in a
particular class of shares.

                            certain redemptions.
 
  Each Fund also issues Class K and Class Y Shares, which have different sales
charges, expense levels and performance. Class K and Class Y Shares are
available to limited types of investors. Call (800) 438-5789 to obtain more
information concerning Class K and Class Y Shares.
 
                        WHAT PRICE DO I PAY FOR SHARES?
 
  The purchase price for Class A Shares is the net asset value ("NAV") next
determined after we receive your order in proper form plus any applicable
sales charge. The purchase price for Class B and Class C Shares is the NAV
next determined after we receive your order in proper form. You should be
aware that broker-dealers (other than the Funds' Distributor) may charge
investors additional fees if shares are purchased through them.
 
  Except in certain limited circumstances, each Fund determines its NAV on
each day the New York Stock Exchange ("NYSE") is open for trading (a "Business
Day") at the close of such trading on the NYSE (normally 4:00 p.m. Eastern
time). Each Fund calculates NAV separately for each class of shares. NAV is
calculated by totaling the value of all of the assets of a Fund allocated to a
particular class of shares, subtracting the Fund's liabilities and expenses
charged to that class and dividing the result by the number of shares of that
class outstanding.
   
  APPLICABLE SALES CHARGE. Except in the circumstances described below, you
must pay a sales charge at the time of purchase of Class A Shares. The sales
charge as a percentage of your investment decreases as the amount you invest
increases. The current sales charge rates and commissions paid to selected
dealers are as follows:

*  No initial sales charge applies on investments of $1 million or more.
   However, a CDSC of 1% is imposed on certain redemptions within one year of
   purchase. Class A Shares of the Trust Funds purchased on or before June 27,
   1995 are subject to a different CDSC, which is described in the SAI.
** The Distributor will pay 1% commission to dealers who initiate and are
   responsible for purchases of $1 million or more.
 
  The Distributor may pay the entire commission to dealers. If that occurs, the
dealer may be considered an "underwriter" under Federal securities laws.
 
  SALES CHARGE WAIVERS. We will waive the initial sales charge on sales of
Class A Shares to the following types of purchasers:
 
   (1) individuals with an investment account or relationship with the
       Advisor;
 
   (2) full-time employees and retired employees of the Advisor, employees of
       the Funds' service providers and immediate family members of such
       persons;
 
   (3) registered broker-dealers that have entered into selling agreements
       with the Distributor, for their own accounts or for retirement plans
       for their employees or sold to registered representatives for full-
       time employees (and their families) that certify to the Distributor at
       the time of purchase that such purchase is for their own account (or
       for the benefit of their families);
 
   (4) certain qualified employee benefit plans as described below;
 
   (5) individuals who reinvest a distribution from a qualified retirement
       plan for which the Advisor serves as investment advisor;
 
   (6) individuals who reinvest the proceeds of redemptions from Class Y
       Shares of the Funds of the Trust, the Company or Framlington, within
       60 days of redemption;
 
   (7) banks and other financial institutions that have entered into
       agreements with the Trust, the Company or Framlington to provide
       shareholder services for customers (including customers of such banks
       and other financial institutions, and the immediate family members of
       such customers);
 
   (8) fee-based financial planners or employee benefit plan consultants
       acting for the accounts of their clients;
     
   (9) employer sponsored retirement plans which are administered by
       Universal Pensions, Inc. ("UPI Plans"); and     
 
  (10) employer sponsored 401(k) plans which are administered by Merrill
       Lynch Group Employee Services ("Merrill Lynch Plans") which meet the
       criteria described below under "Qualified Employer Sponsored
       Retirement Plans."
         
QUALIFIED EMPLOYER SPONSORED RETIREMENT PLANS
 
  We will waive the initial sales charge on purchases of Class A Shares by
employer sponsored retirement plans that are qualified under Section 401(a) or
Section 403(b) of the Code (each, a "Qualified Employee Benefit Plan") and that
(1) invest $1,000,000 or more in Class A Shares of investment portfolios
offered by the Trust, the Company or Framlington or (2) have at least 75
eligible plan participants. In addition, we will waive the CDSC of 1% charged
on certain redemptions within one year of purchase for Qualified Employee
Benefit Plan purchases
 
                                       33
<PAGE>
 
that meet the above criteria. A 1% commission will be paid by the Distributor
to dealers and other entities (as permitted by applicable Federal and state
law) who initiate and are responsible for Qualified Employee Benefit Plan
purchases that meet the above criteria. For purposes of this sales charge
waiver, Simplified Employee Pension Plans ("SEPs"), Individual Retirement
Accounts ("IRAs"), UPI Plans and Merrill Lynch Plans are not considered to be
Qualified Employee Benefit Plans.
 
  We also will waive (i) the initial sales charge on Class A Shares on
purchases by UPI Plans for employees participating in an employer-sponsored or
administered retirement program operating under Section 408A of the Code and
(ii) the CDSC of 1% imposed on certain redemptions within one year of purchase
for these accounts. The Distributor will pay a 1% commission to dealers and
others (as permitted by applicable Federal and state law) who initiate and are
responsible for UPI Plan purchases.
 
  We will waive the initial sales charge for all the investments by Merrill
Lynch Plans if (i) the Plan is recordkept on a daily valuation basis by Merrill
Lynch Group Employee Services ("Merrill Lynch") and, on the date the plan
sponsor ("the Plan Sponsor") signs the Merrill Lynch Recordkeeping Service
Agreement, the Plan has $3 million or more in assets invested in broker/dealer
funds not advised or managed by Merrill Lynch Asset Management, L.P. ("MLAM")
that are made available pursuant to a Services Agreement between Merrill Lynch
and the Funds' principal underwriter or distributor and in funds advised or
managed by MLAM (collectively, the "Applicable Investments"); or (ii) the Plan
is recordkept on a daily valuation basis by an independent recordkeeper whose
services are provided through a contract or alliance arrangement with Merrill
Lynch, and on the date the Plan Sponsor signs the Merrill Lynch Recordkeeping
Service Agreement, the Plan has $3 million or more in assets, excluding money
market funds, invested in Applicable Investments; or (iii) the Plan has 500 or
more eligible employees, as determined by the Merrill Lynch plan conversion
manager, on the date the Plan Sponsor signs the Merrill Lynch Recordkeeping
Service Agreement.
 
  SALES CHARGE REDUCTIONS. You may qualify for reduced sales charges in the
following cases:
 
  . LETTER OF INTENT. If you intend to purchase at least $100,000 of Class A,
    Class B and Class C Shares of the Funds you may wish to complete the
    letter of Intent Section of your Account Application Form. By doing so,
    you agree to invest a certain amount over a 13-month period. You would
    pay a sales charge on any Class A Shares you purchase during the 13
    months based on the total amount to be invested under the Letter of
    Intent. You can apply any investments you made in any of the funds during
    the preceding 90-day period toward fulfillment of the Letter of Intent
    (although there will be no refund of sales charges you paid during the
    90-day period). You should inform the Transfer Agent that you have a
    Letter of Intent each time you make an investment.
 
     You are not obligated to purchase the amount specified in the Letter of
   Intent. If you purchase less than the amount specified, however, you must
   pay the difference between the sales charge paid and the sales charge
   applicable to the purchases actually made. The Custodian will hold such
   amount in escrow. The Custodian will pay the escrowed funds to your
   account at the end of the 13 months unless you do not complete your
   intended investment.
 
  . QUANTITY DISCOUNTS. You may combine purchases of Class A Shares that are
    made by you, your spouse, your children under age 21 and your IRA when
    calculating the sales charge. You must notify your broker or the Transfer
    Agent to qualify.
 
  . RIGHT OF ACCUMULATION. You may add the value of any shares of non-money
    market funds of the Trust, the Company or Framlington you already own to
    the amount of your next Class A Share investment for purposes of
    calculating the sales charge at the time of current purchase. You must
    notify your broker or the Transfer Agent to qualify.
 
  Certain brokers may not offer these programs or may impose conditions on use
of these programs. You should consult with your broker prior to purchasing the
Funds' shares.

at (800) 438-5789.

                          WHEN CAN I PURCHASE SHARES?
 
  Shares of each Fund are sold on a continuous basis and can be purchased on
any Business Day.
 
                    WHAT IS THE MINIMUM REQUIRED INVESTMENT?
 
  The minimum initial investment for Class A, Class B and Class C Shares of a
Fund is $250 and subsequent investments must be at least $50. Purchases in
excess of $250,000 must be for Class A or Class C Shares.
 
                           HOW CAN I PURCHASE SHARES?
 
  You can purchase Class A, Class B and Class C Shares in a number of different
ways. You may place orders directly through the Transfer Agent or the
Distributor or through arrangements with your authorized broker.
 
  . BY BROKER. Any broker authorized by the Distributor can sell you shares
    of the Funds. Please note that brokers may charge you fees for their
    services.
 
  . BY MAIL. You may open an account by completing, signing and mailing the
    attached Account Application Form and a check or other negotiable bank
    draft (payable to The Munder Funds) for $250 or more to: THE MUNDER
    FUNDS, C/O FIRST DATA INVESTOR SERVICES GROUP, P.O. BOX 5130,
    WESTBOROUGH, MASSACHUSETTS 01581-5130. Be sure to specify on your Account
    Application Form the class of shares being purchased. If the class is not
    specified, your purchase will automatically be invested in Class A
    Shares. For additional investments send a letter stating the Fund and
    share class you wish to purchase, your name and your account number with
    a check for $50 or more to the address listed above.
 
  . BY WIRE. To open a new account, you should call the Funds at (800) 438-
    5789 to obtain an account number and complete wire instructions prior to
    wiring any funds. Within seven days of purchase, you must send a
    completed Account Application Form containing your certified taxpayer
    identification number to the Transfer Agent at the address provided
    above. Wire instructions must state the Fund name, share class, your
    registered name and your account number. Your bank wire should be sent
    through the Federal Reserve Bank Wire System to:
 
                            Boston Safe Deposit and Trust Company
                            Boston, MA
                            ABA# 011001234
                            DDA# 16-798-3
                            Account No.:
 
   You may make additional investments at any time using the wire procedures
   described above. Note that banks may charge fees for transmitting wires.
 
  . AUTOMATIC INVESTMENT PLAN ("AIP"). Under the AIP you may arrange for
    periodic investments in a Fund through automatic deductions from a
    checking or savings account. To enroll in the AIP you should complete the
    AIP Application Form or call the Funds at (800) 438-5789. The minimum
    pre-authorized investment amount is $50. You may discontinue the AIP at
    any time. We may discontinue the AIP on 30 days' written notice to you.
 
  . REINVESTMENT PRIVILEGE. Once a year you may reinvest redemption proceeds
    from Class A, B and C Shares of a Fund (or Class A, B and C Shares of
    another non-money market fund of the Trust, the Company or Framlington)
    in shares of the same class of the same Fund without any sales charges,
    if the reinvestment is made within 60 days of redemption. You or your
    broker must notify the Transfer Agent in writing at the time of
    reinvestment in order to eliminate the sales charge.
 
  The Transfer Agent will send you confirmations of the opening of an account
and of all subsequent purchases, exchanges or redemptions in the account. If
your account has been set up by a broker or other investment professional,
account activity will be detailed in their statements to you. We do not issue
share certificates. We reserve the right to (i) reject any purchase order if,
in our opinion, it is in the Funds' best interest to do so and (ii) suspend the
offering of shares of any Class for any period of time.
 
                                       35
<PAGE>
 
  See the SAI for further information regarding purchases of the Funds'
shares.
 
                          HOW CAN I EXCHANGE SHARES?
   
  You may exchange shares of the Funds for shares of the same class of other
funds of the Trust, the Company or Framlington based on their relative net
asset values. Class A Shares of a money market fund of the Trust or the
Company that were (1) acquired through the use of the exchange privilege and
(2) can be traced back to a purchase of shares in one or more funds of the
Trust or the Company for which a sales charge was paid, can be exchanged for
Class A Shares of a fund of the Trust, the Company or Framlington. Class B and
Class C Shares will continue to age from the date of the original purchase and
will retain the same CDSC rate as they had before the exchange.     
   
  You must meet the minimum purchase requirements for the fund of the Trust,
the Company or Framlington that you purchase by exchange. If you are
exchanging into shares of a fund with a higher sales charge, you must pay the
difference at the time of the exchange. Please note that a share exchange is a
taxable event and accordingly, you may realize a taxable gain or loss. Before
making an exchange request, read the Prospectus of the fund you wish to
purchase by exchange. You can obtain a Prospectus for any fund of the Trust,
the Company or Framlington by contacting your broker or the Funds at (800)
438-5789. Brokers may charge a fee for handling exchanges.     
 
  . EXCHANGES BY TELEPHONE. You may give exchange instructions by telephone
    to the Funds at (800) 438-5789. You may not exchange shares by telephone
    if you hold share certificates. We reserve the right to reject any
    telephone exchange request and to place restrictions on telephone
    exchanges.
 
  . EXCHANGES BY MAIL. You may send exchange orders to your broker or to the
    Transfer Agent at The Munder Funds c/o First Data Investor Services
    Group, P.O. Box 5130, Westborough, Massachusetts 01581-5130.
 
  We may modify or terminate the exchange privilege at any time. You will be
given notice of any material modifications except where notice is not
required.
 
                             REDEMPTIONS OF SHARES
 
                 WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?
 
  The redemption price is the NAV next determined after we receive the
redemption request in proper form. We will reduce the amount you receive by
the amount of any applicable CDSC. See "Purchases of Shares--What Price Do I
Pay for Shares?" for an explanation of how the net asset value next determined
is calculated.
 
  CONTINGENT DEFERRED SALES CHARGES. You pay a CDSC when you redeem:
 
  . Class A Shares that are part of an investment of at least $1 million
    within one year of buying them
 
  . Class B Shares within six years of buying them
 
  . Class C Shares within one year of buying them.
   
  These time periods include the time you held Class B or Class C Shares which
you may have exchanged for Class B or Class C Shares of the Fund.     
 
  The CDSC schedule for Class B shares purchased after June 27, 1995 is set
forth below. See the SAI for the CDSC schedule for Class B Shares purchased
before that time. The CDSC is based on the original net asset value at the
time of your investment or the net asset value at the time of redemption,
whichever is lower.

  The Distributor pays sales commissions of 4.00% of the purchase price of
Class B Shares of the Funds to brokers at the time of sale that initiate and
are responsible for purchases of such Class B Shares of the Funds.
 
  You will not pay a CDSC to the extent that the value of the redeemed shares
represents:
 
  .reinvestment of dividends or capital gains distributions
 
  .capital appreciation of shares redeemed.
 
  When you redeem shares, we will assume that you are redeeming first shares
representing reinvestment of dividends and capital gains distributions, then
any appreciation on shares redeemed, and then remaining shares held by you for
the longest period of time. We will calculate the holding period of shares of a
Fund acquired through an exchange of shares of the Munder Money Market Fund
from the date that the shares of the Fund were initially purchased.
 
  CDSC WAIVERS. We will waive the CDSC payable upon redemptions of shares which
you purchased after June 27, 1995 for:
 
  . redemptions made within one year after the death of a shareholder or
    registered joint owner
 
  . minimum required distributions made from an IRA or other retirement plan
    account after you reach age 70 1/2
 
  . involuntary redemptions made by the Fund
 
  . redemptions limited to 10% per year of an account's NAV. For example, if
    you maintain an annual balance of $10,000 you can redeem up to $1,000
    annually free of charge.
 
  Consult the SAI for Class B Share CDSC waivers which apply when you redeem
shares purchased on or before June 27, 1995.
 
  We will waive the CDSC for Class B Shares for all redemptions by Merrill
Lynch Plans if: (i) the Plan is record kept on a daily valuation basis by
Merrill Lynch; or (ii) the Plan is record kept on a daily valuation basis by an
independent record keeper whose services are provided through a contract or
alliance arrangement with Merrill Lynch; or (iii) the Plan has less than 500
eligible employees, as determined by the Merrill Lynch plan conversion manager,
on the date the Plan Sponsor signs the Merrill Lynch Record keeping Service
Agreement.
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. A Fund may temporarily stop redeeming
shares when the NYSE is closed or trading on the NYSE is restricted, when an
emergency exists and the Fund cannot sell its assets or accurately determine
the value of its assets or if the SEC orders the Fund to suspend redemptions.

<PAGE>
 
                            HOW CAN I REDEEM SHARES?
 
  You may redeem shares of the Funds in several ways:
     
  . BY MAIL. You may mail your redemption request to: THE MUNDER FUNDS C/O
    FIRST DATA INVESTOR SERVICES GROUP, P.O. BOX 5130, WESTBOROUGH,
    MASSACHUSETTS 01581-5130. The redemption request should state the name of
    the Fund, share class, account number, amount of redemption, account name
    and where to send the proceeds. All account owners must sign. If a share
    certificate has been issued to you, you must endorse the share
    certificate and return it together with the written redemption request.
        
  . A SIGNATURE GUARANTEE is required for the following redemption requests:
    (a) redemptions proceeds greater than $50,000; (b) redemption proceeds
    not being made payable to the owner of the account; (c) redemption
    proceeds not being mailed to the address of record on the account or (d)
    if the redemption proceeds are being transferred to another Munder Funds
    account with a different registration. You can obtain a signature
    guarantee from a financial institution such as a commercial bank, trust
    company, savings association or from a securities firm having membership
    on a recognized securities exchange.
 
  . BY TELEPHONE. You can redeem your shares by calling your broker or the
    Funds at (800) 438-5789. There is no minimum requirement for telephone
    redemptions paid by check. The Transfer Agent may deduct a wire fee
    (currently $7.50) for wire redemptions under $5,000.
 
     If you are redeeming at least $1,000 of shares and you have authorized
   expedited redemption on your Account Application Form, simply call the
   Fund prior to 4:00 p.m. (Eastern Time), and request the funds be mailed
   to the commercial bank or registered broker-dealer you designated on your
   Account Application Form. We will send your redemption amount to you on
   the next Business Day. We reserve the right at any time to change or
   impose fees for this expedited redemption procedure.
 
     We record all telephone calls for your protection and take measures to
   identify the caller. If the Transfer Agent properly acts on telephone
   instructions and follows the reasonable procedures to ensure against
   unauthorized transactions, neither the Trust, the Company, the
   Distributor nor the Transfer Agent will be responsible for any losses. If
   these procedures are not followed, the Transfer Agent may be liable to
   you for losses resulting from unauthorized instructions.
 
     During periods of unusual economic or market activity, you may
   experience difficulties or delays in effecting telephone redemptions. In
   such cases you should consider placing your redemption request by mail.
 
  . AUTOMATIC WITHDRAWAL PLAN ("AWP"). If you have an account value of $2,500
    or more in a Fund, you may redeem shares on a monthly, quarterly, semi-
    annual or annual basis. The minimum withdrawal is $50. We usually process
    withdrawals on the 20th day of the month and promptly send you your
    redemption amount. You may enroll in the AWP by completing the AWP
    Application Form available through the Transfer Agent. To participate in
    the AWP you must have your dividends automatically reinvested and may not
    hold share certificates. You may change or cancel the AWP at any time
    upon notice to the Transfer Agent. You should not buy Class A Shares (and
    pay a sales charge) while you participate in the AWP and you must pay any
    applicable CDSC's when you redeem shares.
 
  . INVOLUNTARY REDEMPTION. We may redeem your account if its value falls
    below $250 as a result of redemptions (but not as a result of a decline
    in net asset value). You will be notified in writing and allowed 60 days
    to increase the value of your account to the minimum investment level.
 
  . FREE CHECKWRITING. Free checkwriting is available to holders of Class A
    Shares of the Funds (other than the International Bond Fund) who complete
    the Signature Card Section of the Account Application Form. You may write
    checks in the amount of $500 or more but you may not close a Fund account
    by writing a check. We may change or terminate this program on 30 days'
    notice to you.
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  We will typically send redemption amounts to you within seven Business Days
after you redeem shares. We may hold redemption amounts from the sale of shares
you purchased by check until the purchase check has cleared, which may be as
long as 15 days.

                     STRUCTURE AND MANAGEMENT OF THE FUNDS
 
                         HOW ARE THE FUNDS STRUCTURED?
   
  The Trust and the Company are each an open-end management investment
company, which is a mutual fund that sells and redeems shares every day that
it is open for business. They are managed under the direction of their
governing Boards of Trustees and Directors, which are responsible for the
overall management of the Trust and the Company and supervise the Funds'
service providers. The Trust is organized as Massachusetts business trust and
the Company is a Maryland corporation.     
 
                      WHO MANAGES AND SERVICES THE FUNDS?
   
  INVESTMENT ADVISOR. The Funds' investment advisor is Munder Capital
Management, a Delaware general partnership with its principal offices at 480
Pierce Street, Birmingham, Michigan 48009. The principal partners of the
Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM Holdings
II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware corporation
and was a registered investment advisor. WAM and WAM II are Delaware
corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,
1998, the Advisor and its affiliates had approximately $48.2 billion in assets
under management, of which $25.4 billion were invested in equity securities,
$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion
in non-discretionary assets.     
   
  The Advisor provides overall investment management and research and credit
analysis for each Fund and is responsible for all purchases and sales of
portfolio securities for each Fund.     
 
During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate based on the average daily net assets of each Fund
(after waivers, if any) as follows:

  The Advisor may, from time to time, make payments to banks, broker-dealers
or other financial institutions for certain services to the Funds and/or their
shareholders, including sub-administration, sub-transfer agency and
shareholder servicing. The Advisor may make such payments out of its own
resources and there are no additional costs to the Funds or their
shareholders.     
 
  The Advisor selects broker-dealers to execute portfolio transactions for the
Funds based on best price and execution terms. The Advisor may consider as a
factor the number of shares sold by the broker-dealer.
   
  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Funds'
transfer agent. The Transfer Agent is a wholly-owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
01581-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Funds' administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Company and the Trust in all aspects of its administration and operations
including overseeing the maintenance of financial records and fund accounting.
As compensation for its services, State Street is entitled to receive fees,
based on the aggregate daily net assets of the Funds and certain other
investment portfolios that are
 
                                      39
<PAGE>
 
advised by the Advisor for which it provides services, computed daily and
payable monthly at the annual rate of 0.113% on the first $2.8 billion of net
assets, plus 0.103% on the next $2.2 billion of net assets, plus 0.101% on the
next $2.5 billion of net assets, plus 0.095% on the next $2.5 billion of net
assets, plus 0.080% on the next $2.5 billion of net assets, plus 0.070% on all
net assets in excess of $12.5 billion (with a $75,000 minimum fee per annum in
the aggregate for all portfolios with respect to the Administrator).
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Funds. State Street pays the Distributor a fee for
these services out of its own resources at no cost to the Funds.
 
  CUSTODIAN AND SUB-CUSTODIAN. Comercia Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Funds' custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Funds beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Funds. State Street serves as the Funds' sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Funds' shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Funds' shares.
 
  For an additional description of the services performed by the Administrator,
the Transfer Agent, the Custodian, the Sub-Custodian and the Distributor, see
the SAI.
   
  YEAR 2000. The Funds' operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Funds. The Funds have been
informed that their major service providers have made compliance with the Year
2000 Issue a high priority and are taking steps that they believe are
reasonably designed to address the Year 2000 Issue with respect to their
computer systems. There can be, however, no assurance that these steps will be
successful, or that interaction with other non-complying computer systems will
not impair their services at that time.     
 
DISTRIBUTION SERVICES ARRANGEMENT
   
  Under Rule 12b-1 of the Investment Company Act of 1940, as amended, the Funds
have adopted Service Plans with respect to their Class A Shares and Service and
Distribution Plans with respect to their Class B and Class C Shares. Under the
Plans, each Fund uses its assets to finance activities relating to the
distribution of its shares to investors and the provision of certain
shareholder services. The Distributor is paid a service fee at an annual rate
of up to 0.25% of the value of average daily net assets of the Funds' Class A
Shares. The Distributor also is paid a service fee at an annual rate of 0.25%
and a distribution fee at an annual rate of up to 0.75% of the value of the
average daily net assets of the Funds' Class B and Class C Shares. The
Distributor uses the service fees primarily to pay ongoing trail commissions to
securities dealers (which may include the Distributor itself) and other
financial organizations which provide shareholder services for the Funds. These
services include, among other things, processing new shareholder account
applications, reporting to the Funds' Transfer Agent all transactions by
customers and serving as the primary information source to customers concerning
the Funds.     
 
                      WHAT ARE MY RIGHTS AS A SHAREHOLDER?
 
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
the Trust and the Company as a whole and affecting your particular Fund. You
will not vote by class unless expressly required by law or when the Trustees or
Directors determine the matter to be voted on affects only the interests of the
holders of a particular class of shares. The Trust and the Company will not
hold annual
 
                                       40
<PAGE>
 
shareholder meetings, but special meetings may be held at the written request
of shareholders owning more than 10% of outstanding shares for the purpose of
removing a Trustee or Director. Under Massachusetts law, it is possible that a
shareholder may be personally liable for the Trust's obligations. If a
shareholder were required to pay a debt of a Fund, however, the Trust has
committed to reimburse the shareholder in full from its assets. The SAI
contains more information regarding voting rights.
 
  Comerica currently has the right to vote a majority of the outstanding shares
of the Funds as agent, custodian or trustee for its customers and therefore it
is considered to be a controlling person of the Trust and the Company.
 
                       DIVIDENDS, DISTRIBUTIONS AND TAXES
 
               WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUNDS?
 
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on a Fund's investments. The Funds pass their earnings along to
investors in the form of dividends. Dividend distributions are the dividends or
interest earned on investments after expenses. The International Bond Fund pays
dividends quarterly. The other Funds pay dividends monthly. Each Fund
distributes its net realized capital gains (including net short-term capital
gains), if any, at least annually.
   
  It is possible that a Fund may make a distribution in excess of the Fund's
current and accumulated earnings and profits. You will treat such a
distribution as a return of capital which is applied against and reduces your
basis in your shares. You will treat the excess of any such distribution over
your basis in your shares as gain from a sale or exchange of the shares.     
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Funds will pay dividend and capital gains distributions in additional
shares of the same class of a Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Funds at (800) 438-5789.
 
           ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUNDS?
   
  This section contains a brief summary of the tax implications of ownership in
the Funds' shares. A more detailed discussion about the tax treatment of
distributions from the Funds and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Funds, is contained in the SAI. You should
consult your tax advisor regarding the impact of owning the Funds' shares on
your own personal tax situation including the applicability of any state and
local taxes.     
   
  In general, as long as each Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. Each Fund intends to
qualify annually as a RIC. Even if it qualifies as a RIC, a Fund may still be
liable for any excise tax on income that is not distributed in accordance with
a calendar year requirement; the Funds intend to avoid the excise tax by making
timely distributions.     
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains derived from sales of portfolio securities held by a Fund will
generally be designated as long-term or short-term. Distributions from a Fund's
long-term capital gains are generally taxed at the long-term capital gains rate
regardless of how long you have owned shares in the Fund. Dividends from other
sources are generally taxed as ordinary income.
 
                                       41
<PAGE>
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from each Fund in which
you are a shareholder a statement of the amount and nature of the distributions
made to you during the year.
 
  If you redeem, transfer or exchange Fund shares, you may have taxable gain or
a loss. If you hold Fund shares for six months or less, and during that time
you receive a capital gain dividend, any loss you realize on the sale of these
Fund shares will be treated as a long-term loss to the extent of the earlier
distribution.
 
  Dividends and certain interest income earned from foreign securities by a
Fund may be subject to foreign withholding or other taxes. A Fund may be
permitted to pass on to its shareholders the right to a credit or deduction for
income or other tax credits earned from foreign investments and will do so if
possible. These deductions or credits may be subject to tax law limitations.
 
  If a Fund invests in certain "passive foreign investment companies"
("PFICs"), it will be subject to Federal income tax (and possibly additional
interest charges) on a portion of any "excess distribution" or gain from the
disposition of such shares, even if it distributes such income to its
shareholders. If a Fund elects to treat a PFIC as a "qualified electing fund"
("QEF") and the PFIC furnishes certain financial information in the required
form to such Fund, the Fund will instead be required to include in income each
year its allocable share of the ordinary earnings and net capital gains on the
QEF, regardless of whether received, and such amounts will be subject to the
various distribution requirements described above. The Funds may also elect to
mitigate the tax effects of owning PFIC stock by making an annual mark-to-
market election with respect to PFIC shares.
 
                             ADDITIONAL INFORMATION
   
  SHAREHOLDER COMMUNICATIONS. You will receive unaudited Semi-Annual Reports
and audited Annual Reports on a regular basis from the Funds. In addition, you
will also receive updated Prospectuses or Supplements to this Prospectus. In
order to eliminate duplicate mailings the Funds will only send one copy of the
above communications to (1) accounts with the same primary record owner, (2)
joint tenant accounts, (3) tenant in common accounts and (4) accounts which
have the same address.

CLASS A, CLASS B AND CLASS C SHARES
 
  The Munder Funds Trust (the "Trust") and The Munder Funds, Inc. (the
"Company") are open-end investment companies. This Prospectus describes three
investment portfolios offered by the Trust (the "Trust Funds") and the Money
Market Fund offered by the Company (collectively, the "Funds"):
 
                          Munder Cash Investment Fund
                           Munder Money Market Fund

                    Munder U.S. Treasury Money Market Fund

of the Funds. Only Class A Shares of the Trust Funds are currently offered for
sale to retail investors. Class A, Class B and Class C Shares of the Money
Market Fund may be acquired only through an exchange of shares from the
corresponding classes of other funds of the Company, the Trust or The Munder
Framlington Funds Trust ("Framlington").     
 
  This Prospectus explains the objectives, policies, risks and fees of each
Fund. You should read this Prospectus carefully before investing and retain it
for future reference. A Statement of Additional Information ("SAI") describing
each of the Funds has been filed with the Securities and Exchange Commission
(the "SEC") and is incorporated by reference into this Prospectus. You can
obtain the SAI free of charge by calling the Funds at (800) 438-5789. In
addition, the SEC maintains a Web site (http://www.sec.gov) that contains the
SAI and other information regarding the Funds.
   
  SHARES OF THE FUNDS ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY, ANY BANK, AND ARE NOT FEDERALLY INSURED OR GUARANTEED. AN
INVESTMENT IN THE FUNDS INVOLVES INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS
OF THE PRINCIPAL AMOUNT INVESTED.     
 
  ALTHOUGH THE FUNDS SEEK TO MAINTAIN A CONSTANT NET ASSET VALUE OF $1.00 PER
SHARE, THERE CAN BE NO ASSURANCE THAT THE FUNDS CAN DO SO ON A CONTINUING
BASIS.

                                FUND HIGHLIGHTS
 
                  WHAT ARE THE KEY FACTS REGARDING THE FUNDS?
 
Q: What are the Funds' goals?
 
A:
 . The Cash Investment Fund and U.S. Treasury Money Market Fund seek as high
   a level of current interest income as is consistent with maintaining
   liquidity and stability of principal.
 
 . The Money Market Fund seeks to provide current income consistent with the
   preservation of capital and liquidity.
 
 . The Tax-Free Money Market Fund seeks to provide as high a level of current
   interest income exempt from Federal income taxes as is consistent with
   maintaining liquidity and stability of principal.
 
Q: What are the Funds' strategies?
 
A: The Funds invest solely in dollar-denominated debt securities with
remaining maturities of 13 months or less and maintain an average dollar-
weighted portfolio maturity of 90 days or less.
 
Q: What are the Funds' risks?
 
A: It is expected that the Funds will maintain a net asset value of $1.00 per
share, although there is no assurance that they will be able to do so on a
continuous basis. A Fund's performance per share may change daily based on
many factors, including interest rate levels, the quality of the instruments
in the Fund's investment portfolio, national and international economic
conditions and general market conditions.
 
Q: What are the options for investment in the Funds?
 
A: The Money Market Fund offers four different investment options, or classes:
Class A, B, C and Y. The Trust Funds offer only Class A, Class K and Class Y
Shares. Class K and Class Y Shares, which are offered only to institutional
and other qualified investors, are offered in other prospectuses.

*An annual fee for distributing shares and servicing shareholder accounts
   based on the Fund's average daily net assets.
**A one-time fee charged at the time of purchase of shares.
***A contingent deferred sales charge ("CDSC") is a one-time fee charged at
   the time of redemption. The fee declines based on the length of time you
   hold the shares.
 
  Class B Shares convert automatically to Class A Shares after six years. Due
to the level of Rule 12b-1 fees on Class B Shares versus Class A or Class C
Shares, this conversion is to your economic benefit.
 
Q: How do I buy and sell shares of the Funds?
   
A: This Prospectus offers to investors one class of shares of the Trust Funds,
Class A Shares. The Money Market Fund offers Class A, Class B and Class C
Shares which may be acquired only through an exchange of shares of the
corresponding classes of another fund of the Company, the Trust or
Framlington. Funds Distributor, Inc. (the "Distributor") sells shares of the
Funds. You may purchase Class A Shares from the Distributor through broker-
dealers or other financial institutions or from the Funds' transfer agent,
First Data Investor Services Group, Inc. (the "Transfer Agent"), by mailing
the attached Account Application Form with a check to the Transfer Agent. You
must invest at least $250 ($50 through the Automatic Investment Plan)
initially and at least $50 for subsequent purchases.     
 
  Shares may be redeemed (sold back to the Fund) by mail.

  You may also acquire the Funds' shares by exchanging shares of the same
class of other funds of the Company, Munder and Framlington, and exchange Fund
shares for shares of the same class of other funds of the Company, Munder and
Framlington.

Q: When and how are distributions made?
   
A: Dividend distributions are made from the dividends and interest earned on
investments after expenses. The Funds declare dividends daily and pay them
monthly. The Funds distribute capital gains, if any, at least annually. Unless
you elect to receive distributions in cash, we will use all dividends and

    of Class A Shares of other funds purchased on or after June 27, 1995 as
    part of an investment of $1,000,000 or more. See the SAI for a description
    of Class A Shares acquired before June 27, 1995.
(3) The CDSC payable on redemption of Class B Shares declines over time.
(4) A 1% CDSC applies to redemptions within one year after the initial
    investment in Class C Shares.

                            FUND OPERATING EXPENSES
   
  The purpose of this table is to assist you in understanding the expenses
charged directly to each Fund, which investors in the Funds will bear
indirectly for the current fiscal year. Such expenses include payments to
Trustees, Directors, auditors, legal counsel and service providers (such as
the Advisor), registration fees, and distribution fees. The expenses shown
below are based on expenses for the Funds' past fiscal year. Because of the
12b-1 fee, you may over the long term pay more than the amount of the maximum
permitted front-end sales charge.

                            WHAT FUNDS ARE OFFERED?
 
  This Prospectus describes Class A Shares of the Cash Investment Fund, U.S.
Treasury Money Market Fund and Tax-Free Money Market Fund and Class A, B and C
Shares of the Money Market Fund. This section summarizes each Fund's goal and
principal investments. The sections entitled "What are the Funds' Investments
and Investment Practices?" and "What are the Risks of Investing in the Funds?"
and the SAI give more information about the Funds' investment techniques and
risks. Capitalized terms are explained in the section entitled "What are the
Funds' Investments and Investment Practices?"
 
                             CASH INVESTMENT FUND
 
 . The Fund's primary goal is to provide as high a level of current interest
  income as is consistent with maintaining liquidity and stability of
  principal.
 
 . The Fund invests in a broad range of short-term, high quality, U.S. dollar-
  denominated instruments.
 
                        U.S. TREASURY MONEY MARKET FUND
 
 . The Fund's goal is to provide as high a level of current interest income as
  is consistent with maintaining liquidity and stability of principal.
 
 . The Fund invests its assets solely in short-term bonds, bills and notes
  issued by the U.S. Treasury (including "stripped" securities), and in
  repurchase agreements relating to such obligations.
 
                          TAX-FREE MONEY MARKET FUND
 
 . The Fund's goal is to provide as high a level of current interest income
  exempt from Federal income taxes as is consistent with maintaining liquidity
  and stability of principal.
 
 . The Fund invests substantially all of its assets in short-term, U.S. dollar-
  denominated Municipal Obligations, the interest on which is exempt from
  regular Federal income tax.
 
 . Under normal market conditions, the Fund will invest at least 80% of its net
  assets in Municipal Obligations.
 
                               MONEY MARKET FUND
 
 . The Fund's goal is to provide current income consistent with the
  preservation of capital and liquidity.
 
 . The Fund invests its assets in a broad range of short-term, high quality,
  U.S. dollar-denominated instruments, such as bank, commercial and other
  obligations (including Federal, state and local government obligations) that
  are available in the money markets.
 
                     WHO MAY WANT TO INVEST IN THE FUNDS?
 
  The Funds are designed for investors who desire a high level of income and
liquidity, and stability of principal. The Munder Money Market Fund is also
designed to be acquired by the exchange of shares of other Munder Funds for
investors who: (1) own other Munder Funds; (2) wish to be out of the market
temporarily; and (3) do not desire to incur redemption fees or sales charges.
The Funds invest their assets conservatively and as a result, they will not
earn as high a level of current income as funds that invest in longer-term or
lower quality
 
                                      13

debt securities or equity securities. Investors who are more aggressive in
their investment approach or who desire a higher rate of return may wish to
invest in other funds offered by the Trust, the Company and Framlington.
 
           WHAT ARE THE FUNDS' INVESTMENTS AND INVESTMENT PRACTICES?
 
  Each Fund will invest primarily in ELIGIBLE SECURITIES (as defined by the
SEC) with remaining maturities of 397 days or less as defined by the SEC
(although securities subject to repurchase agreements, variable and floating
rate securities and certain other securities may bear longer maturities), and
the dollar-weighted average portfolio maturity of each Fund will not exceed 90
days. Eligible Securities consist of securities that are determined by the
Advisor, under guidelines established by the Boards of Trustees and Directors,
to present minimal credit risk. Each Fund may also hold uninvested cash
pending investment of late payments for purchase orders or during temporary
defensive periods.
 
  Each Fund may BORROW MONEY in an amount up to 5% of its assets for temporary
purposes and in an amount up to 33 1/3% of its assets to meet redemptions.
This is a "fundamental" policy which can be changed only by shareholders.
 
  Each of the Funds may LEND SECURITIES to broker-dealers and other
financially sound institutional investors who will pay the Funds for the use
of the securities, thus increasing the Funds' returns. The borrower must set
aside cash or liquid securities equal to the value of the securities borrowed
at all times during the term of the loan. Loans may not exceed 25% of each
Fund's (except the Money Market Funds) total assets and 33 1/3% of the Money
Market Funds total assets. Risks involved in such transactions include
possible delay in recovering the loaned securities and possible loss of the
securities or the collateral if the borrower declares bankruptcy.

  The following chart summarizes the Funds' investments and investment
practices. The SAI contains more details. All percentages are based on a
Fund's total assets except where otherwise noted. See "What are the Risks of
Investing in the Funds?" for a description of the risks involved with the
Funds' investment practices.

                 WHAT ARE THE RISKS OF INVESTING IN THE FUNDS?
 
  Each Fund attempts to maintain a constant net asset value of $1.00 per
share. However, your investment in the Funds is not guaranteed. By itself, no
Fund is a balanced investment program and there is no guarantee that any Fund
will achieve its investment objective since there is uncertainty in every
investment.
 
  A Fund's risk is mostly dependent on the types of securities it purchases
and its investment techniques. Because the Funds invest mostly in debt
instruments, rises and falls in interest rate levels in general, as well as in
the value of the instruments in the Funds' portfolios, can affect the Funds'
performance.
 
  The Cash Investment Fund and Money Market Fund may invest in securities of
foreign issuers. Foreign securities are generally considered to be riskier
than securities issued by U.S. companies due to factors such as freezes on
convertibility of currency, the rise and fall of foreign currency exchange
rates, political instability and differences in accounting and reporting
standards.
 
  Although the Cash Investment Fund, Money Market Fund and U.S. Treasury Money
Market Fund expect under normal market conditions to be as fully invested as
possible, each Fund may hold uninvested cash pending investment of late
payments for purchase orders (or other payments) or during temporary defensive
periods. Uninvested cash will not earn income. In general, investments in the
Cash Investment Fund, Money Market Fund and U.S. Treasury Money Market Fund
will not earn as high a level of current income as longer-term or lower
quality securities. Longer-term and lower quality securities, however,
generally have less liquidity, greater market risk and more fluctuation in
market value.
 
  Although the Tax-Free Money Market Fund may invest more than 25% of its net
assets in municipal revenue obligations, the interest on which is paid solely
from revenues of similar projects, the Tax-Free Money Market Fund does not
intend to do so on a regular basis. If it does, the Fund will be riskier than
a fund which does not concentrate to such an extent on similar projects.
 
  The risks of the various investment techniques the Funds use are described
in more detail in the SAI.
 
                                  PERFORMANCE
 
                   HOW IS THE FUNDS' PERFORMANCE CALCULATED?
 
  The current yield of shares in the Funds refers to the net income generated
by an investment in shares over a seven-day period (which period will be
stated in the advertisement). This income is then "annualized." That is, the
amount of income generated by the investment during that week is assumed to be
generated each week over 52-week period and is shown as a percentage of the
investment. "Effective yield" is calculated similarly but, when annualized,
the income earned by an investment in a class is assumed to be reinvested. The
"effective yield" will be slightly higher than the "yield" because of the
compounding effect of this assumed reinvestment. The "tax-equivalent yield" of
shares of the Tax-Free Money Market Fund which may also be quoted from time to
time, shows the level of taxable yield needed to produce an after-tax
equivalent to the tax-free yield of a particular class. This is done by
increasing the yield (calculated as above) by the amount necessary to reflect
the payment of Federal and/or state income taxes at a stated rate.
 
  Each Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. The Funds may report how they are
performing in comparison to the Consumer Price Index, an indication of
inflation reported by the U.S. Government.

                     WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Funds' annual report dated June 30 of each year and semi-
annual report dated December 31 of each year, which will automatically be
mailed to shareholders. To obtain copies of financial reports or performance
information, call (800) 438-5789.
 
                       PURCHASES AND EXCHANGES OF SHARES
 
                        WHAT PRICE DO I PAY FOR SHARES?
 
  The purchase price for Class A Shares is the Fund's net asset value ("NAV")
next determined after a purchase order in proper form and payment are
received. You should be aware that broker-dealers (other than the Funds'
Distributor) may charge investors additional fees if shares are purchased
through them.
 
  Except in certain limited circumstances, each Fund determines its NAV on
each day the New York Stock Exchange ("NYSE") is open for trading (a "Business
Day") at 2:45 p.m. (Eastern time) and at the close of trading on the NYSE
(normally 4:00 p.m. Eastern time). If we receive your purchase order and
payment by 2:45 p.m. on a Business Day, you will receive dividends on that
day. Each Fund calculates NAV separately for each class of shares. NAV is
calculated by totaling the value of all of the assets of a Fund allocated to a
particular class of shares, subtracting the Fund's liabilities and expenses
charged to that class and dividing the result by the number of shares of that
class outstanding.
 
                          WHEN CAN I PURCHASE SHARES?
 
  Shares of each Fund are sold on a continuous basis and can be purchased on
any Business Day.
 
                   WHAT IS THE MINIMUM REQUIRED INVESTMENT?
 
  The minimum initial investment for Class A Shares of a Trust Fund is $250
and subsequent investments must be at least $50.
 
                          HOW CAN I PURCHASE SHARES?
 
  You can purchase Class A Shares in a number of different ways. You may place
orders for Class A Shares directly through the Transfer Agent or the
Distributor or through arrangements with your authorized broker. Class A,
Class B and Class C Shares of the Money Market Fund may be acquired only
through an exchange of shares from the corresponding class of another Fund of
the Company, the Trust or Framlington.
 
  . BY BROKER. Any broker authorized by the Distributor can sell you Class A
    Shares of the Funds. Please note that brokers may charge you fees for
    their services.
 
  . BY MAIL. You may open an account by completing, signing and mailing the
    attached Account Application Form and a check or other negotiable bank
    draft (payable to The Munder Funds) for $250 or more to: THE MUNDER
    FUNDS, C/O FIRST DATA INVESTOR SERVICES GROUP, P.O. BOX 5130,
    WESTBOROUGH, MASSACHUSETTS 01581-5130. For additional investments send a
    letter stating the Fund and share class you wish to purchase, your name
    and your account number with a check for $50 or more to the address
    listed above.
 
  . BY WIRE. To open a new account, you should call the Funds at (800) 438-
    5789 to obtain an account number and complete wire instructions prior to
    wiring any funds. Within seven days of purchase, you must send a
    completed Account Application Form containing your certified taxpayer
    identification number to the Transfer Agent at the address provided
    above. Wire instructions must state the Fund
 
                                      18
<PAGE>
 
   name, share class, your registered name and your account number. Your bank
   wire should be sent through the Federal Reserve Bank Wire System to:
 
                           Boston Safe Deposit and Trust Company
                           Boston, MA
                           ABA# 011001234
                           DDA# 16-798-3
                           Account No.:
 
     You may make additional investments at any time using the wire
   procedures described above. Note that banks may charge fees for
   transmitting wires.
 
  . AUTOMATIC INVESTMENT PLAN ("AIP"). Under the AIP you may arrange for
    periodic investments in a Fund through automatic deductions from a
    checking or savings account. To enroll in the AIP you should complete the
    AIP Application Form or call the Funds at (800) 438-5789. The minimum
    pre-authorized investment amount is $50. You may discontinue the AIP at
    any time. We may discontinue the AIP on 30 days' written notice to you.
 
  The Transfer Agent will send you confirmations of the opening of an account
and of all subsequent purchases, exchanges or redemptions in the account. If
your account has been set up by a broker or other investment professional,
account activity will be detailed in their statements to you.
 
  We do not issue share certificates. We reserve the right to (i) reject any
purchase order if, in our opinion, it is in the Funds' best interest to do so
and (ii) suspend the offering of shares of any class for any period of time.
 
  See the SAI for further information regarding purchases of the Funds'
shares.
 
                          HOW CAN I EXCHANGE SHARES?
   
  You may exchange Class A Shares of the Funds for Class A Shares of other
Funds of the Trust, the Company or Framlington based on their relative net
asset values and you may exchange Class B and C Shares of the Money Market
Fund for the corresponding class of shares of the other funds of the Company,
the Trust or Framlington. Class A Shares of the Funds that were (1) acquired
through the use of the exchange privilege and (2) can be traced back to a
purchase of shares in one or more funds of the Trust, the Company or
Framlington for which a sales charge was paid, can be exchanged for Class A
Shares of a fund of the Trust, the Company or Framlington. Class B and Class C
Shares of the Money Market Fund will continue to age from the date of the
original purchase and will retain the same CDSC rate as they had before the
exchange.     
 
  You must meet the minimum purchase requirements for the fund of the Trust,
the Company or Framlington that you purchase by exchange. If you are
exchanging into shares of a fund with a higher sales charge, you must pay the
difference at the time of the exchange. Please note that a share exchange is a
taxable event and accordingly, you may realize a taxable gain or loss. Before
making an exchange request, read the Prospectus of the fund you wish to
purchase by exchange. You can obtain a Prospectus for any fund of the Trust,
the Company or Framlington by contacting your broker or the Funds at (800)
438-5789. Brokers may charge a fee for handling exchanges.
 
  . EXCHANGES BY TELEPHONE. You may give exchange instructions by telephone
    to the Funds at (800) 438-5789. You may not exchange shares by telephone
    if you hold share certificates. We reserve the right to reject any
    telephone exchange request and to place restrictions on telephone
    exchanges.
     
  . EXCHANGES BY MAIL. You may send exchange orders to your broker or to the
    Transfer Agent at The Munder Funds c/o First Data Investor Services
    Group, P.O. Box 5130, Westborough, Massachusetts 01581-5130.     
 
                                      19

  We may modify or terminate the exchange privilege at any time. You will be
given notice of any material modifications except where notice is not
required.
 
                             REDEMPTIONS OF SHARES
 
                 WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?
   
  The redemption price is the NAV next determined after we receive the
redemption request in proper form. If we receive your redemption request by
2:45 p.m. (Eastern time), you will not receive dividends for that day. We will
reduce the amount you receive by the amount of any applicable CDSC. See
"Purchases of Shares--What Price Do I Pay for Shares?" for an explanation of
how the net asset value next determined is calculated.     
 
  CONTINGENT DEFERRED SALES CHARGES. You pay a CDSC when you redeem:
 
  . Class A Shares of the Money Market Fund within one year
 
  . Class A Shares of the Money Market Fund acquired through the exchange of
    Class A Shares of other funds purchased before June 27, 1995 as part of
    an investment of $500,000 or more
 
  . Class B Shares of the Money Market Fund within six years
 
  . Class C Shares of the Money Market Fund within one year.
 
  These time periods include the time you held the shares you exchanged to
acquire Money Market Fund shares.
 
  You pay a 1% CDSC when you redeem Class A Shares of the Money Market Fund:
 
  . that you acquired through the exchange of initial Class A Shares of other
    Funds of the Company, the Trust or Framlington;
 
  . if you acquired the initial Class A Shares after June 27, 1995; and
 
  . if the initial shares were purchased without a sales charge in connection
    with an investment of $1,000,000 or more.
 
  You pay a CDSC of 1% when you redeem Class C Shares of the Money Market Fund
within one year of the date you purchased the initial Class C Shares that you
exchanged to acquire Money Market Fund Shares.
 
  The CDSC schedule for Class B Shares of the Money Market Fund purchased
after June 27, 1995 is set forth below. See the SAI for the CDSC schedule for
Class B Shares purchased before that time. The CDSC is based on the original
purchase price of your investment or the net asset value at the time of
redemption, whichever is lower.

  Redeemed shares will not pay a CDSC to the extent that the value of such
shares represents:
 
  . reinvestment of dividends or capital gains distributions

                                      20
<PAGE>
 
  When you redeem shares, we will assume that you are redeeming first shares
representing reinvestment of dividends and capital gains distributions, then
any appreciation on shares redeemed, and then remaining shares held by you for
the longest period of time.
 
  CDSC WAIVERS. We will waive the CDSC payable upon redemptions of Class B
Shares of the Money Market Fund which you purchased after June 27, 1995 for
 
  . redemptions made within one year after the death of a shareholder or
    registered joint owner
 
  . minimum required distributions made from an IRA or other retirement plan
    account after you reach age 70 1/2
 
  . involuntary redemptions made by the Fund
 
  . redemptions limited to 10% per year of the account's NAV. For example, if
    you maintain an annual balance of $10,000 you can redeem up to $1,000
    annually free of charge.
 
  Consult the SAI for Class A Share CDSC waivers and Class B Share CDSC
waivers which apply when you redeem shares of the Money Market Fund purchased
on or before June 27, 1995.
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. A Fund may temporarily stop
redeeming shares when the NYSE is closed or trading on the NYSE is restricted,
when an emergency exists and the Fund cannot sell its assets or accurately
determine the value of its assets or if the SEC orders the Fund to suspend
redemptions.
 
                           HOW CAN I REDEEM SHARES?
 
  You may redeem shares of the Funds in several ways:
     
  . BY MAIL. You may mail your redemption request to: THE MUNDER FUNDS C/O
    FIRST DATA INVESTOR SERVICES GROUP, P.O. BOX 5130, WESTBOROUGH,
    MASSACHUSETTS 01581-5130. The redemption request should state the name of
    the Fund, share class, account number, amount of redemption, account name
    and where to send the proceeds. All account owners must sign. If a share
    certificate has been issued to you, you must endorse the share
    certificate and return it together with the written redemption request.
        
     A SIGNATURE GUARANTEE is required for the following redemption
   requests: (a) redemptions proceeds greater than $50,000; (b) redemption
   proceeds not being made payable to the owner of the account; (c)
   redemption proceeds not being mailed to the address of record on the
   account or (d) if the redemption proceeds are being transferred to
   another Munder Funds account with a different registration. You can
   obtain a signature guarantee from a financial institution such as a
   commercial bank, trust company, savings association or from a securities
   firm having membership on a recognized securities exchange.
 
  . BY TELEPHONE. You can redeem your shares by calling your broker or the
    Funds at (800) 438-5789. There is no minimum requirement for telephone
    redemptions paid by check. The Transfer Agent may deduct a wire fee
    (currently $7.50) for wire redemptions under $5,000.
 
     If you are redeeming at least $1,000 of shares and you have authorized
   expedited redemption on your Account Application Form, simply call the
   Fund prior to 4:00 p.m. (Eastern Time), and request the funds be mailed
   to the commercial bank or registered broker-dealer you designated on your
   Account Application Form. We will send your redemption amount to you on
   the next Business Day. We reserve the right at any time to change or
   impose fees for this expedited redemption procedure.
 
     We record all telephone calls for your protection and take measures to
   identify the caller. If the Transfer Agent properly acts on telephone
   instructions and follows the reasonable procedures to ensure against
   unauthorized transactions, neither the Trust, the Company, the
   Distributor nor the Transfer Agent will be responsible for any losses. If
   these procedures are not followed, the Transfer Agent may be liable to
   you for losses resulting from unauthorized instructions.
 
 
                                      21
<PAGE>
 
     During periods of unusual economic or market activity, you may
   experience difficulties or delays in effecting telephone redemptions. In
   such cases you should consider placing your redemption request by mail.
 
  . AUTOMATIC WITHDRAWAL PLAN ("AWP"). If you have an account value of $2,500
    or more in a Fund, you may redeem shares on a monthly, quarterly, semi-
    annual or annual basis. The minimum withdrawal is $50. We usually process
    withdrawals on the 20th day of the month and promptly send you your
    redemption amount. You may enroll in the AWP by completing the AWP
    Application Form available through the Transfer Agent. To participate in
    the AWP you must have your dividends automatically reinvested and may not
    hold share certificates. You may change or cancel the AWP at any time
    upon notice to the Transfer Agent. You should not buy Class A Shares (and
    pay a sales charge) while you participate in the AWP and you must pay any
    applicable CDSC's when you redeem shares.
 
  . INVOLUNTARY REDEMPTION. We may redeem your account if its value falls
    below $250 as a result of redemptions (but not as a result of a decline
    in net asset value). You will be notified in writing and allowed 60 days
    to increase the value of your account to the minimum investment level.
 
  . FREE CHECKWRITING. Free checkwriting is available to holders of Class A
    Shares of the Money Market Funds who complete the Signature Card Section
    of the Account Application Form. You may write checks in the amount of
    $500 or more but you may not close a Fund account by writing a check. We
    may change or terminate this program on 30 days' notice to you.
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  We will typically send redemption amounts to you within seven Business Days
after you redeem shares. We may hold redemption amounts from the sale of shares
you purchased by check until the purchase check has cleared, which may be as
long as 15 days.
 
                     STRUCTURE AND MANAGEMENT OF THE FUNDS
 
                         HOW ARE THE FUNDS STRUCTURED?
 
  The Trust and the Company are each an open-end management investment company,
which is a mutual fund that sells and redeems shares every day that it is open
for business. They are managed under the direction of their governing Board of
Trustees and Directors, which are responsible for the overall management of the
Trust and the Company and supervise the Funds' service providers. The Trust is
organized as a Massachusetts business trust and the Company is a Maryland
corporation.
 
                      WHO MANAGES AND SERVICES THE FUNDS?
   
  INVESTMENT ADVISOR. The Funds' investment advisor is Munder Capital
Management, a Delaware general partnership with its principal offices at 480
Pierce Street, Birmingham, Michigan 48009. The principal partners of the
Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM Holdings
II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware corporation
and was a registered investment advisor. WAM and WAM II are Delaware
corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,
1998, the Advisor and its affiliates had approximately $48.2 billion in assets
under management, of which $25.4 billion were invested in equity securities,
$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion in
non-discretionary assets.     
 
  The Advisor provides overall investment management for each Fund, provides
research and credit analysis, and is responsible for all purchases and sales of
portfolio securities.

  During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate based on the average daily net assets of each Fund
(after waivers, if any) as follows:

</TABLE>
   
  The Advisor may, from time to time, make payments to banks, broker-dealers
or other financial institutions for certain services to the Funds and/or their
shareholders, including sub-administration, sub-transfer agency and
shareholder servicing. The Advisor may make such payments out of its own
resources and there are no additional costs to the Funds or their
shareholders.     
 
  The Advisor selects broker-dealers to execute portfolio transactions for the
Funds based on best price and execution terms. The Advisor may consider as a
factor the number of shares sold by the broker-dealer.
   
  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Funds'
transfer agent. The Transfer Agent is a wholly-owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
01581-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Funds' administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Company and the Trust in all aspects of their administration and
operations including overseeing the maintenance of financial records and fund
accounting. As compensation for its services for the Company and the Trust,
State Street is entitled to receive fees, based on the aggregate daily net
assets of the Funds and certain other investment portfolios that are advised
by the Advisor for which it provides services, computed daily and payable
monthly at the annual rate of 0.113% on the first $2.8 billion of net assets,
plus 0.103% on the next $2.2 billion of net assets, plus 0.101% on the next
$2.5 billion of net assets, plus 0.095% on the next $2.5 billion of net
assets, plus 0.080% on the next $2.5 billion of net assets, plus 0.070% on all
net assets in excess of $12.5 billion (with a $75,000 minimum fee per annum in
the aggregate for all portfolios with respect to the Administrator).
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Funds. State Street pays the Distributor a fee
for these services out of its own resources at no cost to the Funds.
 
  CUSTODIAN AND SUB-CUSTODIAN. Comerica Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Funds' custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Funds beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Funds. State Street serves as the Funds' sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Funds' shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Funds' shares.
 
  For an additional description of the services performed by the
Administrator, the Transfer Agent, the Custodian, the Sub-Custodian and the
Distributor, see the SAI.
   
  YEAR 2000. The Funds' operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Funds. The Funds have been
informed that their major service providers have made compliance with the Year
2000 Issue a high priority and are taking steps     
 
                                      23
<PAGE>
 
   
that they believe are reasonably designed to address the Year 2000 Issue with
respect to their computer systems. There can be, however, no assurance that
these steps will be successful, or that interaction with other non-complying
computer systems will not impair their services at that time.     
       
DISTRIBUTION SERVICES ARRANGEMENT
 
  Under Rule 12b-1 of the Investment Company Act of 1940, as amended, the Funds
have adopted Service Plans with respect to their Class A Shares and the Money
Market Fund has adopted Service and Distribution Plans with respect to its
Class B and Class C Shares. Under the Plans, each Fund uses its assets to
finance activities relating to the distribution of its shares to investors and
the provision of certain shareholder services. The Distributor is paid a
service fee at an annual rate of up to 0.25% of the value of average daily net
assets of the Fund's Class A Shares. The Distributor is also paid a service fee
at an annual rate of 0.25% and a distribution fee at an annual rate of up to
0.75% of the value of the average daily net assets of the Money Market Funds'
Class B and Class C Shares. The Distributor uses the service fees primarily to
pay ongoing trail commissions to securities dealers (which may include the
Distributor itself) and other financial organizations which provide shareholder
services for the Funds and the distribution fees to finance activities relating
to the distribution of Money Market Fund's Shares. These services include,
among other things, processing new shareholder account applications, reporting
to the Fund's Transfer Agent all transactions by customers and serving as the
primary information source to customers concerning the Funds.
 
                      WHAT ARE MY RIGHTS AS A SHAREHOLDER?
 
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
the Trust or the Company as a whole and affecting your particular Fund. You
will not vote by class unless expressly required by law or when the Trustees or
Directors determine the matter to be voted on affects only the interests of the
holders of a particular class of shares. The Trust and the Company will not
hold annual shareholder meetings, but special meetings may be held at the
written request of shareholders owning more than 10% of outstanding shares for
the purpose of removing a Trustee or Director. Under Massachusetts law, it is
possible that a shareholder may be personally liable for the Trust's
obligations. If a shareholder were required to pay a debt of a Fund, however,
the Trust is committed to reimburse the shareholder in full from their assets.
The SAI contains more information regarding voting rights.
 
  Comerica Bank currently has the right to vote a majority of the outstanding
shares of the Funds as agent, custodian or trustee for its customers and
therefore it is considered to be a controlling person of the Company and the
Trust.
 
                       DIVIDENDS, DISTRIBUTIONS AND TAXES
 
               WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUNDS?
 
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on a Fund's investments. The Funds pass their earnings along to
investors in the form of dividends. Dividend distributions are the dividends or
interest earned on investments after expenses. The net income of the Funds is
declared daily and paid monthly. Each Fund distributes its net realized capital
gains (including net short-term capital gains), if any, at least annually.
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Funds will pay dividend and capital gains distributions in additional
shares of the same class of a Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Funds at (800) 438-5789.
 
 
                                       24
<PAGE>
 
          ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUNDS?
   
  This section contains a brief summary of the tax implications of ownership
in the Funds' shares. A more detailed discussion about the tax treatment of
distributions from the Funds and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Funds, is contained in the SAI. You should
consult your tax advisor regarding the impact of owning the Funds' shares on
your own personal tax situation including the applicability of any state and
local taxes.     
   
  In general, as long as each Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. Each Fund intends to
qualify annually as a RIC. Even if it qualifies as a RIC, a Fund may still be
liable for any excise tax on income that is not distributed in accordance with
a calendar year requirement; the Funds intend to avoid the excise tax by
making timely distributions.     
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains, if any, derived from sales of portfolio securities held by a
Fund will generally be designated as long-term or short-term. Distributions
from a Fund's long-term capital gains are generally taxed at the long-term
capital gains rate regardless of how long you have owned shares in the Fund.
Dividends from other sources are generally taxed as ordinary income.
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from each Fund in which
you are a shareholder a statement of the amount and nature of the
distributions made to you during the year.
   
  If you redeem, transfer or exchange Fund shares, you may have taxable gain
or a loss. If you hold Fund shares for six months or less, and during that
time you receive a capital gain dividend, any loss you realize on the sale of
these Fund shares will be treated as a long-term loss to the extent of the
earlier distribution.     
 
                            ADDITIONAL INFORMATION
   
  SHAREHOLDER COMMUNICATIONS. You will receive unaudited Semi-Annual Reports
and audited Annual Reports on a regular basis from the Funds. In addition, you
will also receive updated Prospectuses or Supplements to this Prospectus. In
order to eliminate duplicate mailings the Funds will only send one copy of the
above communications to (1) accounts with the same primary record owner, (2)
joint tenant accounts, (3) tenant in common accounts and (4) accounts which
have the same address.

                                FUND HIGHLIGHTS
 
                  WHAT ARE THE KEY FACTS REGARDING THE FUND?
 
Q: What is the Fund's goal?
 
A: The Fund seeks to provide price performance and income that is comparable
to the Standard & Poor's 500 Composite Stock Price Index ("S&P 500").
 
Q: What is the Fund's strategy?
 
A: The Fund invests primarily in equity securities and it normally will hold
the securities of at least 80% of the issuers in the S&P 500. The Fund is
managed through a "quantitative" or "indexing" investment approach, which
attempts to duplicate the investment composition and performance of the S&P
500 through statistical procedures.
 
Q: What are the Fund's risks?
 
A: The Fund's net asset value, which is determined on every business day, will
change daily. The net asset value changes are due to changes in the price of
securities owned by the Fund as a result of rises and falls in the stock
market in general, perceptions about the stocks of particular companies and
perceptions about particular industries. You should note that you could lose a
portion of the amount you invest in the Fund.
 
Q: What are the options for investment in the Fund?
 
A: The Fund has registered five classes of shares: Class A, B, C, K and Y.
Class K and Y Shares, which are only offered to institutional and other
qualified investors, are offered in other prospectuses. Class C Shares are not
currently offered for sale.

*An annual fee for distributing shares and servicing shareholder accounts paid
   based on the Fund's average daily net assets.
**A one-time fee charged at the time of purchase of shares. The fee declines
   based on the amount you invest.
***A contingent deferred sales charge ("CDSC") is a one-time fee charged at
   the time of redemption. The fee declines based on the length of time you
   hold the shares.
+A CDSC of 1% is imposed on certain redemptions of Class A Shares if redeemed
   within 1 year of purchase.
 
  (i) If you invest over $250,000, you must buy Class A or Class C Shares.
(ii) Class B Shares convert automatically to Class A Shares after six years.
Due to the level of Rule 12b-1 fees and the CDSC on Class B Shares versus
Class A or Class C Shares, both (i) and (ii) above are to your economic
benefit.
 
Q: How do I buy and sell shares of the Fund?
   
A: Funds Distributor, Inc. (the "Distributor") sells shares of the Fund. You
may purchase shares from the Distributor through broker-dealers or other
financial institutions or from the Fund's transfer agent, First Data Investor
Services Group, Inc. (the "Transfer Agent"), by mailing the attached Account
Application Form with a check to the Transfer Agent. You must invest at least
$250 ($50 through the Automatic Investment Plan) initially and at least $50
for subsequent purchases.     
 
  Shares may be redeemed (sold back to the Fund) by mail or by telephone.
 
  You may also acquire the Fund's shares by exchanging shares of the same
class of other funds of the Trust, The Munder Funds, Inc. (the "Company") and
The Munder Framlington Funds Trust ("Framlington"), and exchange Fund shares
for shares of the same class of other funds of the Trust, the Company and
Framlington.

                            FUND OPERATING EXPENSES
   
  The purpose of this table is to assist you in understanding the expenses
charged directly to the Fund, which investors in the Fund will bear indirectly
for the current fiscal year. Such expenses include payments to Trustees,
auditors, legal counsel and service providers (such as the Advisor),
registration fees, and distribution fees. The expenses shown below are based
on expenses for the Fund's past fiscal year. Because of the 12b-1 fee, you may
over the long term pay more than the amount of the maximum permitted front-end
sales charge.

+The Advisor expects to voluntarily waive a portion of its advisory fee during
   the current fiscal year and the Distributor expects to voluntarily waive a
   portion of its Rule 12b-1 fees with respect to Class A Shares and Class B
   Shares. Class A Shares of the Fund pay a Rule 12b-1 fee up to .25% of the
   value of average daily net assets and Class B Shares of the Fund pay a Rule
   12b-1 fee of up to 1.00% of the value of average daily net assets. (The
   Advisor and/or the Distributor may discontinue such waivers at any time in
   their sole discretion. Without waivers the ratio of advisory fees to
   average daily net assets would be .13% and the ratio of 12b-1 fees to
   average daily net assets would be .25% for Class A Shares and 1.00% for
   Class B Shares. Without waivers total operating expenses would be 0.60% for
   Class A Shares, 1.35% for Class B Shares and 1.35% for Class C Shares.

                               FUND INFORMATION
   
  This Prospectus describes Class A, Class B and Class C Shares of the Fund.
This section summarizes the Fund's principal investments. The sections
entitled "What are the Fund's Investments and Investment Practices?" and "What
are the Risks of Investing in the Fund?" and the SAI give more information
about the Fund's investment techniques and risks.     
 
  GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide performance
and income that is comparable to the S&P 500. The S&P 500 is an index of 500
stocks which emphasize large capitalization companies. See Appendix A for more
information on the S&P 500. The Fund will normally hold the securities of at
least 400 of the stocks in the S&P 500.
 
  The Fund will try to achieve a correlation between the performance of its
portfolio and that of the S&P 500 of at least .95. A correlation of 1.0 would
mean that the changes in the Fund's price mirror exactly changes in the S&P
500. The timing of purchases and redemptions, changes in securities markets,
level of the Fund's assets and other factors affect the Fund's ability to
exactly track the S&P 500's performance.
 
  The Fund is managed through the use of a "quantitative" investment approach
and tries to mirror the composition and performance of the S&P 500 through
statistical procedures. The Advisor does not use traditional methods of fund
investment management, i.e., it does not select stocks on the basis of
economic, financial and market analysis. Because the Fund pays brokerage costs
and other fees, its return may be lower than that of the S&P 500.
 
  PORTFOLIO MANAGEMENT. Todd B. Johnson and Kenneth A. Schluchter III jointly
manage the Fund. Mr. Johnson, a Chief Investment Officer of the Advisor, has
served as the portfolio manager of the Fund since July 1992. Mr. Schluchter,
who has managed the Fund since June 1997, was previously a Systems Developer
and Data Analyst for Compuware Incorporated (1993-1995) and a Business Analyst
for Central Transport Incorporated (1989-1993).
 
                      WHO MAY WANT TO INVEST IN THE FUND?
 
  The Fund is designed for investors who desire potentially high capital
appreciation and who can accept short-term variations in return for
potentially greater returns over the long term. In general, the greater the
risk, the greater the potential reward. Investors who have a short time
horizon, who desire a high level of income or who are conservative in their
investment approach may wish to invest in other portfolios offered by the
Trust.
 
           WHAT ARE THE FUND'S INVESTMENTS AND INVESTMENT PRACTICES?
 
  The Fund will invest in EQUITY SECURITIES, which includes common stocks,
preferred stocks, warrants and other securities convertible into common
stocks, including convertible bonds and convertible preferred stocks. Many of
the common stocks the Fund will buy will not pay dividends; instead, stocks
will be bought for the potential that their prices will increase, providing
capital appreciation for the Fund. The value of Equity Securities will
fluctuate due to many factors, including the past and predicted earnings of
the issuer, the quality of the issuer's management, general market conditions,
the forecasts for the issuer's industry and the value of the issuer's assets.
Holders of Equity Securities only have rights to value in the company after
all debts have been paid, and they could lose their entire investment in a
company that encounters financial difficulty. Warrants are rights to purchase
securities at a specified time at a specified price.
 
  The Fund may invest in FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS, which
are obligations of the Fund to purchase or sell a specific currency at a
future date at a set price. These contracts may decrease the Fund's loss due
to a change in currency value, but also limits gains from currency exchanges.
   
  The Fund may invest in CASH EQUIVALENTS, which are high-quality, short-term
instruments including, among other things, commercial paper, bankers'
acceptances and negotiable certificates of deposit of banks or savings     
 
                                      10
<PAGE>
 
and loan associations, short-term corporate obligations and short-term
securities issued by, or guaranteed by, the U.S. Government and its agencies
or instrumentalities. These instruments will be used primarily pending
investment, to meet anticipated redemptions or as a temporary defensive
measure.
 
  The Fund may invest in FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.
Futures contracts are contracts in which the Fund agrees, at maturity, to make
delivery of or receive securities, the cash value of an index, or foreign
currency. Futures contracts and options on futures contracts are used for
hedging purposes or to maintain liquidity. The Fund may not purchase or sell a
futures contract unless immediately after any such transaction the sum of the
aggregate amount of margin deposits on its existing futures positions and the
amount of premiums paid for related options is 5% or less of its total assets.
The Fund will set aside cash or other liquid securities to "cover" the Fund's
position in futures.
 
  The Fund may purchase or sell OPTIONS. The Fund may buy options giving it
the right to require a buyer to buy a security held by the Fund (put options),
buy options giving it the right to require a seller to sell securities to the
Fund (call options), sell (write) options giving a buyer the right to require
the Fund to buy securities from the buyer or write options giving a buyer the
right to require the Fund to sell securities to the buyer during a set time at
a set price. Options may relate to stock indices or individual securities. See
the SAI for more details and additional limitations.
 
  The Fund may purchase securities on a "WHEN-ISSUED" basis and may purchase
or sell securities on a "FORWARD COMMITMENT" basis. Although the price to be
paid by the Fund is set at the time of the agreement, the Fund usually does
not pay for securities until they are received. The value of the securities
may change between the time the price is set and the time the price is paid.
When the Fund purchases securities for future delivery, the Fund's custodian
will set aside cash or other liquid securities to "cover" the Fund's position.
The Fund does not intend to purchase securities for future delivery for
speculative purposes.
   
  The Fund may enter into REPURCHASE AGREEMENTS. Under a repurchase agreement,
the Fund agrees to purchase securities from a seller and the seller agrees to
repurchase the securities at a later time, typically within seven days, at a
set price. The seller agrees to set aside collateral at least equal to the
repurchase price. This ensures that the Fund will receive the purchase price
at the time it is due, unless the seller defaults or declares bankruptcy, in
which event the Fund will bear the risk of possible loss due to adverse market
action or delays in liquidating the underlying obligation.     
 
  The Fund may invest in REVERSE REPURCHASE AGREEMENTS. Under a reverse
repurchase agreement, the Fund sells securities and agrees to buy them back
later at an agreed upon time and price. Reverse repurchase agreements are used
to borrow money for temporary purposes.
 
  The Fund may LEND SECURITIES to broker-dealers and other financially sound
institutional investors who will pay the Fund for the use of the securities,
thus potentially increasing the Fund's returns. The borrower must set aside
cash or liquid securities equal to the value of the securities borrowed at all
times during the terms of the loan. Loans may not exceed 25% of the value of
the Fund's total assets. Risks involved in such transactions include possible
delay in recovering the loaned securities and possible loss of the securities
or the collateral if the borrower fails financially.
   
  The Fund may purchase AMERICAN DEPOSITARY RECEIPTS ("ADRS"), EUROPEAN
DEPOSITARY RECEIPTS ("EDRS") AND GLOBAL DEPOSITARY RECEIPTS ("GDRS"). ADRs are
issued by U.S. financial institutions and EDRs and GDRs are issued by European
financial institutions. They are receipts evidencing ownership of underlying
foreign securities.     
 
  The Fund may buy shares of registered MONEY MARKET FUNDS. The Fund will bear
a portion of the expenses of any investment company whose shares they
purchase, including operating costs and investment advisory, distribution and
administration fees. These expenses would be in addition to the Fund's own
expenses. The Fund may invest up to 10% of its assets in other investment
companies and no more than 5% of its assets in any one investment company.
 
                                      11
<PAGE>
 
  The Fund may invest up to 15% of the value of its net assets in ILLIQUID
SECURITIES. Illiquid Securities are securities for which there is no ready
market, which inhibits the ability to sell them and obtain their full market
value, or which are legally restricted as to their resale by the Fund.
 
  The Fund may purchase FIXED INCOME SECURITIES. Fixed Income Securities are
securities which either pay interest at set times at either fixed or variable
rates, or which realize a discount upon maturity. Fixed Income Securities
include corporate bonds, debentures, notes and other similar corporate debt
instruments, zero coupon bonds (discount debt obligations that do not make
interest payments) and variable amount master demand notes that permit the
amount of indebtedness to vary in addition to providing for periodic
adjustments in the interest rate. The Fund may purchase U.S. GOVERNMENT
SECURITIES, which are securities issued by, or guaranteed by, the U.S.
Government or its agencies or instrumentalities. Such securities include U.S.
Treasury bills, which have initial maturities of less than one year, U.S.
Treasury notes, which have initial maturities of one to ten years, U.S.
Treasury bonds, which generally have initial maturities of greater than ten
years, and obligations of the Federal Home Loan Mortgage Corporation, Federal
National Mortgage Association and Government National Mortgage Association.
Under normal market conditions, the Fund will not invest to a significant
extent, or on a routine basis, in U.S. Government Securities.
 
  The Fund may BORROW MONEY in an amount up to 5% of its assets for temporary
purposes and in an amount up to 33 1/3% of its assets to meet redemptions.
This is a "fundamental" policy which can be changed only by shareholders.
 
  The Fund may invest up to 25% of its assets in FOREIGN SECURITIES. Foreign
Securities are securities issued by non-U.S. companies. Investments in Foreign
Securities are riskier than investments in U.S. companies because (i) foreign
companies may be subject to different accounting, auditing and financial
reporting standards than U.S. companies, (ii) there is generally less public
information available about foreign companies, (iii) there may be less
governmental regulation and supervision of foreign stock exchanges, securities
markets and companies and (iv) foreign securities markets may be less liquid
and more volatile than U.S. securities markets.
 
                 WHAT ARE THE RISKS OF INVESTING IN THE FUND?
 
  The Fund is not meant to provide a vehicle for playing short-term swings in
the stock market. Consistent with a long-term investment approach, investors
in the Fund should be prepared and able to maintain their investments during
periods of adverse market conditions. By itself, no Fund is a balanced
investment program and there is no guarantee that any Fund will achieve its
investment objective since there is uncertainty in every investment.
 
  Investing in the Fund may be less risky than investing in individual stocks
due to the diversification of investing in a portfolio of many different
stocks; however, such diversification does not eliminate all risks. Because
the Fund invests mostly in Equity Securities, rises and falls in the stock
market in general, as well as in the value of particular Equity Securities
held by the Fund, can affect the Fund's performance. Your investment in the
Fund is not guaranteed. The net asset value of the Fund will change daily and
you might not recoup the amount you invest in the Fund.
 
  A Fund's risk is mostly dependent on the types of securities it purchases
and its investment techniques. The Fund is authorized to use options, futures
and forward foreign currency exchange contracts, which are types of derivative
instruments. Derivative instruments are instruments that derive their value
from a different underlying security, index or financial indicator. The use of
derivative instruments exposes the Fund to additional risks and transaction
costs. Risks inherent in the use of derivative instruments include: (1) the
risk that interest rates, securities prices and currency markets will not move
in the direction that a portfolio manager anticipates; (2) imperfect
correlation between the price of derivative instruments and movements in the
prices of the securities, interest rates or currencies being hedged; (3) the
fact that skills needed to use these strategies are different than those
needed to select portfolio securities; (4) the possible absence of a liquid
secondary market for any particular instrument and possible exchange-imposed
price fluctuation limits, either of which may make it difficult or
 
                                      12
<PAGE>
 
impossible to close out a position when desired; (5) leverage risk, that is,
the risk that adverse price movements in an instrument can result in a loss
substantially greater than the Fund's initial investment in that instrument
(in some cases, the potential loss is unlimited); and (6) particularly in the
case of privately-negotiated instruments, the risk that the counterparty will
fail to perform its obligations, which could leave the Fund worse off than if
it had not entered into the position.
 
  To the extent that a Fund invests in illiquid securities, the Fund risks not
being able to sell securities at the time and the price that it would like.
The Fund may therefore have to lower the price, sell substitute securities or
forego an investment opportunity, each of which might adversely affect the
Fund.
 
  The risks of the various investment techniques the Fund uses are described
in more detail in the SAI.
 
                                  PERFORMANCE
 
                   HOW IS THE FUND'S PERFORMANCE CALCULATED?
 
  There are various ways in which the Fund may calculate and report its
performance. Performance is calculated separately for each class of shares.
 
  One method is to show the Fund's total return. Cumulative total return is
the percentage change in the value of an amount invested in a class of shares
of the Fund over a stated period of time and takes into account reinvested
dividends plus in the case of Class A Shares, the payment of the maximum sales
charge and, in the case of Class B and Class C Shares, the maximum CDSC.
Cumulative total return most closely reflects the actual performance of the
Fund. However, a shareholder who opts to receive dividends in cash, a Class A
shareholder who paid a sales charge lower than the maximum sales charge, or a
Class B or C shareholder who paid lower than the maximum CDSC will have a
different return than the reported performance.
 
  Average annual total return refers to the average annual compounded rates of
return over a specified period on an investment in shares of the Fund
determined by comparing the initial amount invested to the ending redeemable
value of the amount, taking into account reinvested dividends, the payment of
the maximum sales charge on Class A Shares, and the payment of the maximum
CDSC on Class B and Class C Shares.
 
  The Fund may also publish its current yield. Yield is the net investment
income generated by a share of the Fund during a 30-day period divided by the
maximum offering price on the 30th day. "Maximum offering price" includes the
sales charge for Class A Shares.
 
  The Fund may sometimes publish total returns that do not take into account
sales charges and such returns will be higher than returns which include sales
charges. You should be aware that (i) past performance does not indicate how
the Fund will perform in the future and (ii) the Fund's return and net asset
value will fluctuate, so you cannot necessarily use the Fund's performance
data to compare it to investment in certificates of deposit, savings accounts
or other investments that provide a fixed or guaranteed yield.
 
  The Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. The Fund may also compare its total return
to the S&P 500 and other broad-based indices. These indices show the value of
selected portfolios of securities (assuming reinvestment of interest and
dividends) which are not managed by a portfolio manager. The Fund may report
how it is performing in comparison to the Consumer Price Index, an indication
of inflation reported by the U.S. Government.

<PAGE>
 
                     WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Fund's annual report dated June 30 of each year and semi-
annual report dated December 31 of each year, which will automatically be
mailed to shareholders. To obtain copies of financial reports or performance
information, call (800) 438-5789.
 
                       PURCHASES AND EXCHANGES OF SHARES
 
             WHICH SHARE CLASS SHOULD I CHOOSE FOR MY INVESTMENT?
 
  The Fund has registered Class A, Class B and Class C Shares and currently
offers Class A and Class B Shares. Each Class has its own cost structure,
allowing you to choose the one that best meets your requirements given the
amount of your purchase and the intended length of your investment. You should
consider both ongoing annual expenses and initial or contingent deferred sales
charges in estimating the costs of investing in a particular class of shares.

                             thus reducing future

                             certain redemptions.
 
  The Fund also issues Class K and Class Y Shares, which have different sales
charges, expense levels and performance. Class K and Class Y Shares are
available to limited types of investors. Call (800) 438-5789 to obtain more
information concerning Class K and Class Y Shares.
 
                        WHAT PRICE DO I PAY FOR SHARES?
 
  The purchase price for Class A Shares is the net asset value ("NAV") next
determined after we receive your order in proper form PLUS any applicable
sales charge. The purchase price for Class B and Class C Shares is the NAV
next determined. You should be aware that broker-dealers (other than the
Fund's Distributor) may charge investors additional fees if shares are
purchased through them.
 
  Except in certain limited circumstances, the Fund determines its NAV on each
day the New York Stock Exchange ("NYSE") is open for trading (a "Business
Day") at the close of such trading (normally 4:00 p.m. Eastern time). The Fund
calculates NAV separately for each class of shares. NAV is calculated by
totaling the value of all of the assets of the Fund allocated to a particular
class of shares, subtracting the Fund's liabilities and expenses charged to
that class and dividing the result by the number of shares of that class
outstanding.

  APPLICABLE SALES CHARGE. Except in the circumstances described below, you
must pay a sales charge at the time of purchase of Class A Shares. The sales
charge as a percentage of your investment decreases as the amount you invest
increases. The current sales charge rates and commissions paid to selected
dealers are as follows:

   redemption if such shares are redeemed within one year after the date of
   purchase.
 
  The Distributor may pay the entire commission to dealers. If that occurs,
the dealer may be considered an "underwriter" under Federal securities laws.

  SALES CHARGE REDUCTIONS. You may qualify for reduced sales charges in the
following cases:     
 
  . LETTER OF INTENT. If you intend to purchase at least $500,000 of Class A,
    Class B and Class C Shares of the Fund and other non-money market funds
    of the Trust, the Company or Framlington, you may wish to complete the
    Letter of Intent Section of your Account Application Form. By doing so,
    you agree to invest a certain amount over a 13-month period. You would
    pay a sales charge on any Class A Shares you purchase during the 13
    months based on the total amount to be invested under the Letter of
    Intent. You can apply any investments you made in any of the funds during
    the preceding 90-day period toward fulfillment of the Letter of Intent
    (although there will be no refund of sales charges you paid during the
    90-day period). You should inform the Transfer Agent that you have a
    Letter of Intent each time you make an investment.
 
     You are not obligated to purchase the amount specified in the Letter of
   Intent. If you purchase less than the amount specified, however, you must
   pay the difference between the sales charge paid and the sales charge
   applicable to the purchases actually made. The Custodian will hold such
   amount in escrow. The Custodian will pay the escrowed funds to your
   account at the end of the 13 months unless you do not complete your
   intended investment.
 
  . QUANTITY DISCOUNTS. You may combine purchases of Class A Shares that are
    made by you, your spouse, your children under age 21 and your IRA when
    calculating the sales charge. You must notify your broker or the Transfer
    Agent to qualify.
 
  . RIGHT OF ACCUMULATION. You may add the value of any Class A, Class B and
    Class C Shares of non-money market funds of the Trust, the Company or
    Framlington you already own to the amount of your next Class A Share
    investment for purposes of calculating the sales charge at the time of
    current purchase. You must notify your broker or the Transfer Agent to
    qualify.

  See the SAI for further information regarding purchases of the Fund's
shares.
 
                          HOW CAN I EXCHANGE SHARES?
 
  You may exchange shares of the Fund for shares of the same class of other
funds of the Trust, the Company or Framlington based on their relative net
asset values. Class A Shares of a money market fund of the Trust or the
Company that were (1) acquired through an exchange and (2) can be traced back
to a purchase of shares in one or more funds of the Trust or the Company for
which a sales charge was paid, can be exchanged for Class A Shares of a fund
of the Trust, the Company or Framlington. Class B and Class C Shares will
continue to age from the date of the original purchase and will retain the
same CDSC rate as they had before the exchange.
 
  You must meet the minimum purchase requirements for the fund of the Trust,
the Company or Framlington that you purchase by exchange. If you are
exchanging into shares of a fund with a higher sales charge, you must pay the
difference at the time of exchange. Please note that a share exchange is a
taxable event and accordingly, you may realize a taxable gain or loss. Before
making an exchange request, read the Prospectus of the fund you wish to
purchase by exchange. You can obtain a Prospectus for any fund of the Trust,
the Company or Framlington by contacting your broker or the Funds at (800)
438-5789. Brokers may charge a fee for handling exchanges.
 
  . EXCHANGES BY TELEPHONE. You may give exchange instructions by telephone
    to the Fund at (800) 438-5789. You may not exchange shares by telephone
    if you hold share certificates. We reserve the right to reject any
    telephone exchange request and to place restrictions on telephone
    exchanges.
 
  . EXCHANGES BY MAIL. You may send exchange orders to your broker or to the
    Transfer Agent at The Munder Funds c/o First Data Investor Services
    Group, P.O. Box 5130, Westborough, Massachusetts, 01581-5130.
 
  We may modify or terminate the exchange privilege at any time. You will be
given notice of any material modifications except where notice is not
required.
 
                             REDEMPTIONS OF SHARES
 
                 WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?
 
  The redemption price is the NAV next determined after we receive the
redemption request in proper form. We will reduce the amount you receive by
the amount of any applicable CDSC. See "Purchases of Shares--What Price Do I
Pay for Shares?" for an explanation of how the net asset value next determined
is calculated.
 
  CONTINGENT DEFERRED SALES CHARGES. You pay a CDSC when you redeem:
 
  .Class A Shares that are part of an investment of at least $500,000 within
  one year of buying them
 
  .Class B Shares within six years of buying them
 
  .Class C Shares within one year of buying them.
 
  These time periods include the time you held Class B or Class C Shares which
you may have exchanged for Class B or Class C Shares of the Fund.
 
                                      18

  The CDSC schedule for Class B Shares purchased after June 27, 1995 is set
forth below. See the SAI for the CDSC schedule for Class B Shares purchased
before that time. The CDSC is based on the original net asset value at the
time of purchase of your investment or the net asset value at the time of
redemption, whichever is lower.

  The Distributor pays sales commissions of 2.00% of the purchase price of
Class B Shares of the Fund to brokers at the time of sale that initiate and
are responsible for purchases of such Class B Shares of the Fund.
 
  You will not pay a CDSC to the extent that the value of the redeemed shares
represents:
 
  .reinvestment of dividends or capital gains distributions
 
  .capital appreciation of shares redeemed.
 
  When you redeem shares, we will assume that you are redeeming first shares
representing reinvestment of dividends and capital gains distributions, then
any appreciation on shares redeemed, and then remaining shares held by you for
the longest period of time. We will calculate the holding period of shares of
a Fund acquired through an exchange of shares of the Munder Money Market Fund
from the date that the shares of the Fund were initially purchased.
 
  CDSC WAIVERS. We will waive the CDSC payable upon redemptions of shares
which you purchased after June 27, 1995 for:
 
  .redemptions made within one year after the death of a shareholder or
  registered joint owner
 
  .minimum required distributions made from an IRA or other retirement plan
     account after you reach age 70 1/2
 
  .involuntary redemptions made by the Fund
 
  . redemptions limited to 10% per year of the account's NAV. For example, if
    you maintain an annual balance of $10,000 you can redeem up to $1,000
    annually free of charge.
 
  Consult the SAI for Class B Share CDSC waivers which apply when you redeem
shares acquired in an exchange of shares of another Fund of the Company or the
Trust that were purchased on or before June 27, 1995.
   
  We will waive the CDSC for Class B Shares for all redemptions by Merrill
Lynch Plans if: (i) the Plan is record kept on a daily valuation basis by
Merrill Lynch; or (ii) the Plan is record kept on a daily valuation basis by
an independent recordkeeper whose services are provided through a contract or
alliance arrangement with Merrill Lynch; or (iii) the Plan has less than 500
eligible employees, as determined by the Merrill Lynch plan conversion
manager, on the date the Plan Sponsor signs the Merrill Lynch Recordkeeping
Service Agreement.     
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. The Fund may temporarily stop
redeeming shares when the NYSE is closed or trading on the NYSE is restricted,
when an emergency exists and the Fund cannot sell its assets or accurately
determine the value of its assets or if the SEC orders the Fund to suspend
redemptions.

<PAGE>
 
                           HOW CAN I REDEEM SHARES?
 
  You may redeem shares of the Fund in several ways.
     
  . BY MAIL. You may mail your redemption request to: THE MUNDER FUNDS, C/O
    FIRST DATA INVESTOR SERVICES GROUP P.O. BOX 5130, WESTBOROUGH,
    MASSACHUSETTS 01581-5130. The redemption request should state the name of
    the Fund, share class, account number, amount of redemption, account name
    and where to send the proceeds. All account owners must sign. If a share
    certificate has been issued to you, you must endorse the share
    certificate and return it together with the written redemption request.
        
     A SIGNATURE GUARANTEE is required for the following redemption requests:
   (a) redemption proceeds greater than $50,000; (b) redemption proceeds not
   being made payable to the owner of the account; (c) redemption proceeds
   not being mailed to the address of record on the account or (d) if the
   redemption proceeds are being transferred to another Munder Funds account
   with a different registration. You can obtain a signature guarantee from a
   financial institution such as a commercial bank, trust company, savings
   association or from a securities firm having membership on a recognized
   securities exchange.
 
  . BY TELEPHONE. You can redeem your shares by calling your broker or the
    Fund at (800) 438-5789. There is no minimum requirement for telephone
    redemptions paid by check. The Transfer Agent may deduct a wire fee
    (currently $7.50) for wire redemptions under $5,000.
 
     If you are redeeming at least $1,000 of shares and you have authorized
   expedited redemption on your Account Application Form, simply call the
   Fund prior to 4:00 p.m. (Eastern time), and request the funds be mailed to
   the commercial bank or registered broker-dealer you designated on your
   Account Application Form. We will send your redemption amount to you on
   the next business day. We reserve the right at any time to change or
   impose fees for this expedited redemption procedure.
 
     We record all telephone calls for your protection and take measures to
   identify the caller. If the Transfer Agent properly acts on telephone
   instructions and follows the reasonable procedures to ensure against
   unauthorized transactions, neither the Trust, the Distributor nor the
   Transfer Agent will be responsible for any losses. If these procedures are
   not followed, the Transfer Agent may be liable to you for losses resulting
   from unauthorized instructions.
 
     During periods of unusual economic or market activity, you may
   experience difficulties or delays in effecting telephone redemptions. In
   such cases you should consider placing your redemption request by mail.
 
  . AUTOMATIC WITHDRAWAL PLAN ("AWP"). If you have an account value of $2,500
    or more in the Fund, you may redeem shares on a monthly, quarterly, semi-
    annual or annual basis. The minimum withdrawal is $50. We usually process
    withdrawals on the 20th day of the month and promptly send you your
    redemption amount. You may enroll in the AWP by completing the AWP
    Application Form available through the Transfer Agent. To participate in
    the AWP you must have your dividends automatically reinvested and may not
    hold share certificates. You may change or cancel the AWP at any time
    upon notice to the Transfer Agent. You should not buy Class A Shares (and
    pay a sales charge) while you participate in the AWP and you must pay any
    applicable CDSC's when you redeem shares.
 
  . INVOLUNTARY REDEMPTION. We may redeem your account if its value falls
    below $250 as a result of redemptions (but not as a result of a decline
    in net asset value). You will be notified in writing and allowed 60 days
    to increase the value of your account to the minimum investment level.
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  We will typically send redemption amounts to you within seven Business Days
after you redeem shares. We may hold redemption amounts from the sale of
shares you purchased by check until the purchase check has cleared, which may
be as long as 15 days.

                     STRUCTURE AND MANAGEMENT OF THE FUND
 
                          HOW IS THE FUND STRUCTURED?
 
  The Trust is an open-end management investment company, which is a mutual
fund that sells and redeems shares every day that it is open for business. The
Trust is managed under the direction of its Board of Trustees which is
responsible for the overall management of the Trust and supervises the Fund's
service providers. The Trust is organized as a Massachusetts business trust.
 
                      WHO MANAGES AND SERVICES THE FUND?
   
  INVESTMENT ADVISOR. The Fund's investment advisor is Munder Capital
Management, a Delaware general partnership with its principal offices at 480
Pierce Street, Birmingham, Michigan 48009. The principal partners of the
Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM Holdings
II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware corporation
and was a registered investment advisor. WAM and WAM II are Delaware
corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,
1998, the Advisor and its affiliates had approximately $48.2 billion in assets
under management, of which $25.4 billion were invested in equity securities,
$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion
in non-discretionary assets.     
   
  The Advisor provides overall investment management and research and credit
analysis for the Fund and is responsible for all purchases and sales of
portfolio securities for the Fund.     
 
  During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate of .07% of the average daily net assets of the Fund
(after waivers and/or expense reimbursements). The Advisor waived advisory
fees during the past fiscal year for the Fund. The Advisor is entitled to
receive an annual fee equal to .20% of the first $250 million of the Fund's
average daily net assets, .12% of the next $250 million of the Fund's average
daily net assets and .07% of the Fund's average daily net assets over $500
million.
   
  The Advisor may, from time to time, make payments to banks, broker-dealers
or other financial institutions for certain services to the Fund and/or its
shareholders, including sub-administration, sub-transfer agency and
shareholder servicing. The Advisor may make such payments out of its own
resources and there are no additional costs to the Fund or its shareholders.
    
  The Advisor selects broker-dealers to execute portfolio transactions for the
Fund based on best price and execution terms. The Advisor may consider as a
factor the number of shares sold by the broker-dealer.
   
  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Fund's
transfer agent. The Transfer Agent is a wholly-owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
01581-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Fund's administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Trust in all aspects of its administration and operations including
overseeing the maintenance of financial records and fund accounting. As
compensation for its services, State Street is entitled to receive fees, based
on the aggregate daily net assets of the Fund and certain other investment
portfolios that are advised by the Advisor for which it provides services,
computed daily and payable monthly at the annual rate of 0.113% on the first
$2.8 billion of net assets, plus 0.103% on the next $2.2 billion of net
assets, plus 0.101% on the next $2.5 billion of net assets, plus 0.095% on the
next $2.5 billion of net assets, plus 0.080% on the next $2.5 billion of net
assets, plus 0.070% on all net assets in excess of $12.5 billion (with a
$75,000 minimum fee per annum in the aggregate for all portfolios with respect
to the Administrator).
 
                                      21
<PAGE>
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Fund. State Street pays the Distributor a fee for
these services out of its own resources at no cost to the Fund.
 
  CUSTODIAN AND SUB-CUSTODIAN. Comerica Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Fund's custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Fund beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Fund. State Street serves as the Fund's sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Fund's shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Fund's shares.
 
  For an additional description of the services performed by the
Administrator, the Transfer Agent, the Custodian, the Sub-Custodian and the
Distributor, see the SAI.
   
  YEAR 2000. The Fund's operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Fund. The Fund has been informed
that its major service providers have made compliance with the Year 2000 Issue
a high priority and are taking steps that they believe are reasonably designed
to address the Year 2000 Issue with respect to their computer systems. There
can be, however, no assurance that these steps will be successful, or that
interaction with other non-complying computer systems will not impair their
services at that time.     
 
DISTRIBUTION SERVICES ARRANGEMENT
   
  Under Rule 12b-1 of the Investment Company Act of 1940, as amended, the Fund
has adopted a Service Plan with respect to its Class A Shares and Service and
Distribution Plans with respect to its Class B and Class C Shares. Under the
Plans, the Fund uses its assets to finance activities relating to the
distribution of its shares to investors and the provision of certain
shareholder services. The Distributor is paid a service fee at an annual rate
of up to 0.25% of the value of average daily net assets of the Fund's Class A
Shares. The Distributor also is paid a service fee at an annual rate of up to
0.25% and a distribution fee at an annual rate of up to 0.75% of the value of
the average daily net assets of the Fund's Class B and Class C Shares. The
Distributor uses the service fees primarily to pay ongoing trail commissions
to securities dealers (which may include the Distributor itself) and other
financial organizations which provide shareholder services for the Fund. These
services include, among other things, processing new shareholder account
applications, reporting to the Transfer Agent all transactions by customers
and serving as the primary information source to customers concerning the
Fund.     
 
                     WHAT ARE MY RIGHTS AS A SHAREHOLDER?
   
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
the Trust as a whole and affecting the Fund. You will not vote by class unless
expressly required by law or when the Trustees determine the matter to be
voted on affects only the interests of the holders of a particular class of
shares. The Trust will not hold annual shareholder meetings, but special
meetings may be held at the written request of shareholders owning more than
10% of outstanding shares for the purpose of removing a Trustee. Under
Massachusetts law, it is possible that a shareholder may be personally liable
for the Trust's obligations. If a shareholder were required to pay a debt of
the Fund, however, the Trust has committed to reimburse the shareholder in
full from its assets. The SAI contains more information regarding voting
rights.     
 
                                      22
<PAGE>
 
  Comerica currently has the right to vote a majority of the outstanding
shares of the Fund as agent, custodian or trustee for its customers and
therefore it is considered to be a controlling person of the Trust.
 
                      DIVIDENDS, DISTRIBUTIONS AND TAXES
 
               WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUND?
 
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on the Fund's investments. The Fund passes its earnings along
to investors in the form of dividends. Dividend distributions are the
dividends or interest earned on investments after expenses. The net income of
the Fund, if any, is paid quarterly as a dividend. The Fund distributes its
net realized capital gains (including net short-term capital gains), if any,
at least annually.
   
  It is possible that a Fund may make a distribution in excess of the Fund's
current and accumulated earnings and profits. You will treat such a
distribution as a return of capital which is applied against and reduces your
basis in your shares. You will treat the excess of any such distribution over
your basis in your shares as gain from a sale or exchange of the shares.     
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Fund will pay dividend and capital gains distributions in additional
shares of the same class of the Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Fund at (800) 438-5789.
 
           ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUND?
   
  This section contains a brief summary of the tax implications of ownership
in the Fund's shares. A more detailed discussion about the tax treatment of
distributions from the Fund and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Fund, is contained in the SAI. You should
consult your tax advisor regarding the impact of owning the Fund's shares on
your own personal tax situation including the applicability of any state and
local taxes.     
   
  In general, as long as the Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. The Fund intends to
qualify annually as a RIC. Even if it qualifies as a RIC, the Fund may still
be liable for any excise tax on income that is not distributed in accordance
with a calendar year requirement; the Fund intends to avoid the excise tax by
making timely distributions.     
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains derived from sales of portfolio securities held by the Fund
will generally be designated as long-term or short-term. Distributions from
the Fund's long-term capital gains are generally taxed at the long-term
capital gains rate regardless of how long you have owned shares in the Fund.
Dividends from other sources are generally taxed as ordinary income.
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from the Fund a statement
of the amount and nature of the distributions made to you during the year.
 
                                      23
<PAGE>
 
  If you redeem, transfer or exchange Fund shares, you may have taxable gain
or a loss. If you hold Fund shares for six months or less, and during that
time you receive a capital gain dividend, any loss you realize on the sale of
these Fund shares will be treated as a long-term loss to the extent of the
earlier distribution.
 
  Dividends and certain interest income earned from foreign securities by the
Fund may be subject to foreign withholding or other taxes. The Fund may be
permitted to pass on to its shareholders the right to a credit or deduction
for income or other tax credits earned from foreign investments and it intends
to do so if possible. These deductions or credits may be subject to tax law
limitations.
 
  If the Fund invests in certain "passive foreign investment companies"
("PFICs"), it will be subject to Federal income tax (and possibly additional
interest charges) on a portion of any "excess distribution" or gain from the
disposition of such shares, even if it distributes such income to its
shareholders. If the Fund elects to treat a PFIC as a "qualified electing
fund" ("QEF") and the PFIC furnishes certain financial information in the
required form to the Fund, the Fund will instead be required to include in
income each year its allocable share of the ordinary earnings and net capital
gains of the QEF, regardless of whether received, and such amounts will be
subject to the various distribution requirements described above. The Fund may
also elect to mitigate the tax effects of owning PFIC stock by making an

By signing the application, I(we) hereby certify under the penalty of perjury
that the information on this application is true, complete and correct and that:

I(We) understand that this order is subject to acceptance by The Munder Funds.

I(We) agree that The Munder Funds, Funds Distributor, Inc., First Data, Munder
Capital Management or any of its affiliates, officers, directors or employees
will not be liable for any loss, expense or cost for acting upon instructions or
inquiries reasonably believed to be genuine. Shares of the Funds are not insured

Board, or any other agency. An investment in the Funds involves investment
risks, including the possible loss of principal.

I(We) represent that I am (we are) of legal age and capacity and have read the

First Data, is hereby appointed agent to receive dividends and distributions for
automatic reinvestment unless otherwise directed in Section 4.

I(We) understand and acknowledge that a sales charge may be levied against the

reduced sales charge information.)

The Internal Revenue Service requires that all taxpayers provide their Taxpayer
Identification Numbers (Social Security Numbers) and sign in the space provided
below. Failure by non-exempt taxpayers to furnish us with the correct Taxpayer
Identification Number will result in withholding of 31% of all taxable dividends
paid and/or withholding on certain other payments (this is referred to as backup
withholding).


- --------------------------------------------------------------------------------
Taxpayer Identification Number    Name of Taxpayer Whose Number Appears Above


Taxpayer Identification:

I (the Investor) certify under penalties of perjury that:

(1)  The Social Security Number or taxpayer identification number shown above is
     correct and may be used for any custodial or trust account opened for me by
     The Munder Funds, and

(2)  I (the Investor) am not subject to backup withholding because:

     (a) I am exempt from Backup Withholding

     (b) I have not been notified by the Internal Revenue Service ("IRS") that
         I am, as a result of failure to report all interest or dividends, or

     (c) the IRS has notified me that I am no longer subject to backup
         withholding.

The certification in this paragraph is required from all non-exempt persons to
prevent backup withholding of 31% of all taxable distributions and gross
redemption proceeds under the Federal income tax law.

[_] Check here if you are subject to backup withholding or have not received a
    notice from the IRS advising you that backup withholding has been
    terminated.

                                FUND HIGHLIGHTS
 
                  WHAT ARE THE KEY FACTS REGARDING THE FUND?
 
Q: What is the Fund's goal?
 
A: The Fund seeks to provide price performance and income that is comparable
to the Standard & Poor's 500 Composite Stock Price Index ("S&P 500").
 
Q: What is the Fund's strategy?
 
A: The Fund invests primarily in equity securities and it normally will hold
the securities of at least 80% of the issuers in the S&P 500. The Fund is
managed through a "quantitative" or "indexing" investment approach, which
attempts to duplicate the investment composition and performance of the S&P
500 through statistical procedures.
 
Q: What are the Fund's risks?
 
A: The Fund's net asset value, which is determined on every business day, will
change daily. The net asset value changes are due to changes in the price of
securities owned by the Fund as a result of rises and falls in the stock
market in general, perceptions about the stocks of particular companies and
perceptions about particular industries. You should note that you could lose a
portion of the amount you invest in the Fund.
 
Q: What are the options for investment in the Fund?
 
A: The Fund has registered five classes of shares: Class A, B, C, K and Y.
Class A, B, C and K Shares are described in other prospectuses. Class C Shares
are not currently offered for sale.
 
Q: How do I buy and sell shares of the Fund?
 
A: Funds Distributor, Inc. (the "Distributor") sells shares of the Fund. You
may purchase shares from the Distributor through broker-dealers or other
financial institutions or from the Fund's transfer agent, First Data Investor
Services Group, Inc. (the "Transfer Agent"), by mailing the Account
Application Form with a check to the Transfer Agent. Fiduciary and
discretionary accounts of institutions and institutional investors must invest
at least $500,000 initially. Other types of investors are not subject to any
minimum required investment.
 
  Shares may be redeemed (sold back to the Fund) by mail or by telephone.
 
  You may also acquire the Fund's shares by exchanging shares of the same
class of other funds of the Trust, The Munder Funds, Inc. (the "Company") and
The Munder Framlington Funds Trust ("Framlington"), and exchange Fund shares
for shares of the same class of other funds of the Trust, the Company and
Framlington.
 
Q: What shareholder privileges does the Fund offer?
 
A:
 . Automatic Investment Plan
 
 . Retirement Plan
 
 . Telephone Exchanges
 
 . Reinvestment Privilege
 
 . Redemption By Check
 
Q: When and how are distributions made?
   
A: Dividend distributions are made from the dividends and interest earned on
investments after expenses. The Fund pays dividends at least quarterly (if
income is available) and distributes capital gains, if any, at least annually.
Unless you elect to receive distributions in cash, all dividends and capital
gain distributions will be automatically used to purchase additional shares of
the Fund.     
 
Q: Who manages the Fund's assets?
 
A: Munder Capital Management is the Fund's investment advisor. The Advisor is
responsible for all purchases and sales of the securities held by the Fund.

                            FUND OPERATING EXPENSES
   
  The purpose of this table is to assist you in understanding the expenses
charged directly to the Fund, which investors in the Fund will bear indirectly
for the current fiscal year. Such expenses include payments to Trustees,
auditors, legal counsel and service providers (such as the Advisor) and
registration fees. The expenses shown below are based on expenses for the

</TABLE>

*The Advisor expects to voluntarily waive a portion of its advisory fee during
   the current fiscal year. Without waivers the ratio of advisory fees to
   average daily net assets would be .13% and total fund operating expenses
   would be .35%. The Advisor may discontinue such waiver at any time in its
   sole discretion.     
 
                                    EXAMPLE
 
  This example shows the amount of expenses you would pay (directly or
indirectly) on a $1,000 investment in the Fund assuming (1) a 5% annual
return, (2) redemption at the end of the time periods (including the deduction
of the deferred sales charge, if any) and (3) no redemption at the end of the
time periods. THIS EXAMPLE IS NOT A REPRESENTATION OF PAST OR FUTURE
PERFORMANCE OR OPERATING EXPENSES; ACTUAL PERFORMANCE OR OPERATING EXPENSES
MAY BE LARGER OR SMALLER THAN THOSE SHOWN.

  The Fund will try to achieve a correlation between the performance of its
portfolio and that of the S&P 500 of at least .95. A correlation of 1.0 would
mean that the changes in the Fund's price mirror exactly changes in the S&P
500. The timing of purchases and redemptions, changes in securities markets,
level of the Fund's assets and other factors affect the Fund's ability to
exactly track the S&P 500's performance.
 
  The Fund is managed through the use of a "quantitative" investment approach
and tries to mirror the composition and performance of the S&P 500 through
statistical procedures. The Advisor does not use traditional methods of fund
investment management, i.e., it does not select stocks on the basis of
economic, financial and market analysis. Because the Fund pays brokerage costs
and other fees, its return may be lower than that of the S&P 500.
 
  PORTFOLIO MANAGEMENT. Todd B. Johnson and Kenneth A. Schluchter III jointly
manage the Fund. Mr. Johnson, a Chief Investment Officer of the Advisor, has
served as the portfolio manager of the Fund since July 1992. Mr. Schluchter,
who has managed the Fund since June 1997, was previously a Systems Developer
and Data Analyst for Compuware Incorporated (1993-1995) and a Business Analyst
for Central Transport Incorporated (1989-1993).
 
                      WHO MAY WANT TO INVEST IN THE FUND?
 
  The Fund is designed for investors who desire potentially high capital
appreciation and who can accept short-term variations in return for
potentially greater returns over the long term. In general, the greater the
risk, the greater the potential reward. Investors who have a short time
horizon, who desire a high level of income or who are conservative in their
investment approach may wish to invest in other portfolios offered by the
Trust.
 
           WHAT ARE THE FUND'S INVESTMENTS AND INVESTMENT PRACTICES?
 
  The Fund will invest in EQUITY SECURITIES, which includes common stocks,
preferred stocks, warrants and other securities convertible into common
stocks, including convertible bonds and convertible preferred stocks. Many of
the common stocks the Fund will buy will not pay dividends; instead, stocks
will be bought for the potential that their prices will increase, providing
capital appreciation for the Fund. The value of Equity Securities will
fluctuate due to many factors, including the past and predicted earnings of
the issuer, the quality of the issuer's management, general market conditions,
the forecasts for the issuer's industry and the value of the issuer's assets.
Holders of Equity Securities only have rights to value in the company after
all debts have been paid, and they could lose their entire investment in a
company that encounters financial difficulty. Warrants are rights to purchase
securities at a specified time at a specified price.
 
  The Fund may invest in FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS, which
are obligations of the Fund to purchase or sell a specific currency at a
future date at a set price. These contracts may decrease the Fund's loss due
to a change in currency value, but also limits gains from currency exchanges.
   
  The Fund may invest in CASH EQUIVALENTS, which are high-quality, short-term
instruments including, among other things, commercial paper, bankers'
acceptances and negotiable certificates of deposit of banks or savings     
 
                                       7
<PAGE>
 
and loan associations, short-term corporate obligations and short-term
securities issued by, or guaranteed by, the U.S. Government and its agencies
or instrumentalities. These instruments will be used primarily pending
investment, to meet anticipated redemptions or as a temporary defensive
measure.
 
  The Fund may invest in FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.
Futures contracts are contracts in which the Fund agrees, at maturity, to make
delivery of or receive securities, the cash value of an index, or foreign
currency. Futures contracts and options on futures contracts are used for
hedging purposes or to maintain liquidity. The Fund may not purchase or sell a
futures contract unless immediately after any such transaction the sum of the
aggregate amount of margin deposits on its existing futures positions and the
amount of premiums paid for related options is 5% or less of its total assets.
The Fund will set aside cash or other liquid securities to "cover" the Fund's
position in futures.
 
  The Fund may purchase or sell OPTIONS. The Fund may buy options giving it
the right to require a buyer to buy a security held by the Fund (put options),
buy options giving it the right to require a seller to sell securities to the
Fund (call options), sell (write) options giving a buyer the right to require
the Fund to buy securities from the buyer or write options giving a buyer the
right to require the Fund to sell securities to the buyer during a set time at
a set price. Options may relate to stock indices or individual securities. See
the SAI for more details and additional limitations.
 
  The Fund may purchase securities on a "WHEN-ISSUED" basis and may purchase
or sell securities on a "FORWARD COMMITMENT" basis. Although the price to be
paid by the Fund is set at the time of the agreement, the Fund usually does
not pay for securities until they are received. The value of the securities
may change between the time the price is set and the time the price is paid.
When the Fund purchases securities for future delivery, the Fund's custodian
will set aside cash or other liquid securities to "cover" the Fund's position.
The Fund does not intend to purchase securities for future delivery for
speculative purposes.
   
  The Fund may enter into REPURCHASE AGREEMENTS. Under a repurchase agreement,
the Fund agrees to purchase securities from a seller and the seller agrees to
repurchase the securities at a later time, typically within seven days, at a
set price. The seller agrees to set aside collateral at least equal to the
repurchase price. This ensures that the Fund will receive the purchase price
at the time it is due, unless the seller defaults or declares bankruptcy, in
which event the Fund will bear the risk of possible loss due to adverse market
action or delays in liquidating the underlying obligation.     
 
  The Fund may invest in REVERSE REPURCHASE AGREEMENTS. Under a reverse
repurchase agreement, the Fund sells securities and agrees to buy them back
later at an agreed upon time and price. Reverse repurchase agreements are used
to borrow money for temporary purposes.
 
  The Fund may LEND SECURITIES to broker-dealers and other financially sound
institutional investors who will pay the Fund for the use of the securities,
thus potentially increasing the Fund's returns. The borrower must set aside
cash or liquid securities equal to the value of the securities borrowed at all
times during the terms of the loan. Loans may not exceed 25% of the value of
the Fund's total assets. Risks involved in such transactions include possible
delay in recovering the loaned securities and possible loss of the securities
or the collateral if the borrower fails financially.
   
  The Fund may purchase AMERICAN DEPOSITARY RECEIPTS ("ADRS"), EUROPEAN
DEPOSITARY RECEIPTS ("EDRS") AND GLOBAL DEPOSITARY RECEIPTS ("GDRS"). ADRs are
issued by U.S. financial institutions and EDRs and GDRs are issued by European
financial institutions. They are receipts evidencing ownership of underlying
foreign securities.     
 
  The Fund may buy shares of registered MONEY MARKET FUNDS. The Fund will bear
a portion of the expenses of any investment company whose shares they
purchase, including operating costs and investment advisory, distribution and
administration fees. These expenses would be in addition to the Fund's own
expenses. The Fund may invest up to 10% of its assets in other investment
companies and no more than 5% of its assets in any one investment company.
 
                                       8
<PAGE>
 
  The Fund may invest up to 15% of the value of its net assets in ILLIQUID
SECURITIES. Illiquid Securities are securities for which there is no ready
market, which inhibits the ability to sell them and obtain their full market
value, or which are legally restricted as to their resale by the Fund.
 
  The Fund may purchase FIXED INCOME SECURITIES. Fixed Income Securities are
securities which either pay interest at set times at either fixed or variable
rates, or which realize a discount upon maturity. Fixed Income Securities
include corporate bonds, debentures, notes and other similar corporate debt
instruments, zero coupon bonds (discount debt obligations that do not make
interest payments) and variable amount master demand notes that permit the
amount of indebtedness to vary in addition to providing for periodic
adjustments in the interest rate. The Fund may purchase U.S. GOVERNMENT
SECURITIES, which are securities issued by, or guaranteed by, the U.S.
Government or its agencies or instrumentalities. Such securities include U.S.
Treasury bills, which have initial maturities of less than one year, U.S.
Treasury notes, which have initial maturities of one to ten years, U.S.
Treasury bonds, which generally have initial maturities of greater than ten
years, and obligations of the Federal Home Loan Mortgage Corporation, Federal
National Mortgage Association and Government National Mortgage Association.
Under normal market conditions, the Fund will not invest to a significant
extent, or on a routine basis, in U.S. Government Securities.
 
  The Fund may BORROW MONEY in an amount up to 5% of its assets for temporary
purposes and in an amount up to 33 1/3% of its assets to meet redemptions.
This is a "fundamental" policy which can be changed only by shareholders.
 
  The Fund may invest up to 25% of its assets in FOREIGN SECURITIES. Foreign
Securities are securities issued by non-U.S. companies. Investments in Foreign
Securities are riskier than investments in U.S. companies because (i) foreign
companies may be subject to different accounting, auditing and financial
reporting standards than U.S. companies, (ii) there is generally less public
information available about foreign companies, (iii) there may be less
governmental regulation and supervision of foreign stock exchanges, securities
markets and companies and (iv) foreign securities markets may be less liquid
and more volatile than U.S. securities markets.
 
                 WHAT ARE THE RISKS OF INVESTING IN THE FUND?
       
  Investing in the Fund may be less risky than investing in individual stocks
due to the diversification of investing in a portfolio of many different
stocks; however, such diversification does not eliminate all risks. Because
the Fund invests mostly in Equity Securities, rises and falls in the stock
market in general, as well as in the value of particular Equity Securities
held by the Fund, can affect the Fund's performance. Your investment in the
Fund is not guaranteed. The net asset value of the Fund will change daily and
you might not recoup the amount you invest in the Fund.
   
  The Fund is not meant to provide a vehicle for playing short-term swings in
the stock market. Consistent with a long-term investment approach, investors
in the Fund should be prepared and able to maintain their investments during
periods of adverse market conditions. By itself, no Fund is a balanced
investment program and there is no guarantee that any Fund will achieve its
investment objective since there is uncertainty in every investment.     
 
  A Fund's risk is mostly dependent on the types of securities it purchases
and its investment techniques. The Fund is authorized to use options, futures
and forward foreign currency exchange contracts, which are types of derivative
instruments. Derivative instruments are instruments that derive their value
from a different underlying security, index or financial indicator. The use of
derivative instruments exposes the Fund to additional risks and transaction
costs. Risks inherent in the use of derivative instruments include: (1) the
risk that interest rates, securities prices and currency markets will not move
in the direction that a portfolio manager anticipates; (2) imperfect
correlation between the price of derivative instruments and movements in the
prices of the securities, interest rates or currencies being hedged; (3) the
fact that skills needed to use these strategies are different than those
needed to select portfolio securities; (4) the possible absence of a liquid
secondary market for any particular
 
                                       9
<PAGE>
 
instrument and possible exchange-imposed price fluctuation limits, either of
which may make it difficult or impossible to close out a position when
desired; (5) leverage risk, that is, the risk that adverse price movements in
an instrument can result in a loss substantially greater than the Fund's
initial investment in that instrument (in some cases, the potential loss is
unlimited); and (6) particularly in the case of privately-negotiated
instruments, the risk that the counterparty will fail to perform its
obligations, which could leave the Fund worse off than if it had not entered
into the position.
 
  To the extent that a Fund invests in illiquid securities, the Fund risks not
being able to sell securities at the time and the price that it would like.
The Fund may therefore have to lower the price, sell substitute securities or
forego an investment opportunity, each of which might adversely affect the
Fund.
 
  The risks of the various investment techniques the Fund uses are described
in more detail in the SAI.
 
                                  PERFORMANCE
 
                   HOW IS THE FUND'S PERFORMANCE CALCULATED?
 
  There are various ways in which the Fund may calculate and report its
performance. Performance is calculated separately for each class of shares.
 
  One method is to show the Fund's total return. Cumulative total return is
the percentage change in the value of an amount invested in a class of shares
of the Fund over a stated period of time and takes into account reinvested
dividends. Cumulative total return most closely reflects the actual
performance of the Fund.
 
  Average annual total return refers to the average annual compounded rates of
return over a specified period on an investment in shares of the Fund
determined by comparing the initial amount invested to the ending redeemable
value of the amount, taking into account reinvested dividends.
 
  The Fund may also publish its current yield. Yield is the net investment
income generated by a share of the Fund during a 30-day period divided by the
maximum offering price on the 30th day.
 
  You should be aware that (i) past performance does not indicate how the Fund
will perform in the future and (ii) the Fund's return and net asset value will
fluctuate, so you cannot necessarily use the Fund's performance data to
compare it to investment in certificates of deposit, savings accounts or other
investments that provide a fixed or guaranteed yield.
 
  The Fund may compare its performance to that of other mutual funds, such as
the performance of similar funds reported by Lipper Analytical Services, Inc.
or information reported in national financial publications (such as Money
Magazine, Forbes, Barron's, The Wall Street Journal and The New York Times) or
in local or regional publications. The Fund may also compare its total return
to the S&P 500 and other broad-based indices. These indices show the value of
selected portfolios of securities (assuming reinvestment of interest and
dividends) which are not managed by a portfolio manager. The Fund may report
how it is performing in comparison to the Consumer Price Index, an indication
of inflation reported by the U.S. Government.
 
                     WHERE CAN I OBTAIN PERFORMANCE DATA?
 
  The Wall Street Journal and certain local newspapers report information on
the performance of mutual funds. In addition, performance information is
contained in the Fund's annual report dated June 30 of each year and semi-
annual report dated December 31 of each year, which will automatically be
mailed to shareholders. To obtain copies of financial reports or performance
information, call (800) 438-5789.

                       PURCHASES AND EXCHANGES OF SHARES
 
  The following persons may purchase Class Y Shares:
 
  . fiduciary and discretionary accounts of institutions;
 
  . institutional investors (including banks, savings institutions, credit
    unions and other financial institutions, pension, profit sharing and
    employee benefit plans and trusts, insurance companies, investment
    companies, investment advisors and broker-dealers acting either for their
    own accounts or for the accounts of institutional investors);
 
  . directors, trustees, officers and employees of the Trust, the Company,
    Framlington, the Advisor and the Distributor;
     
  . the Advisor's investment advisory clients; and     
 
  . family members of employees of the Advisor.
 
  The Fund also has registered Class A, B, C and K Shares, which have
different sales charges, expense levels and performance. Class K Shares are
available to limited types of investors. Call (800) 438-5789 to obtain more
information concerning the Fund's other classes of shares.
 
                        WHAT PRICE DO I PAY FOR SHARES?
 
  The purchase price for Class Y Shares is the net asset value ("NAV") next
determined after we receive your order in proper form without any sales
charge. You should be aware that broker-dealers (other than the Fund's
Distributor) may charge investors additional fees if shares are purchased
through them.
 
  Except in certain limited circumstances, the Fund determines its NAV on each
day the New York Stock Exchange ("NYSE") is open for trading (a "Business
Day") at the close of such trading (normally 4:00 p.m. Eastern time). The Fund
calculates NAV separately for each class of shares. NAV is calculated by
totaling the value of all of the assets of the Fund allocated to a particular
class of shares, subtracting the Fund's liabilities and expenses charged to
that class and dividing the result by the number of shares of that class
outstanding.
 
                          WHEN CAN I PURCHASE SHARES?
 
  Shares of the Fund are sold on a continuous basis and can be purchased on
any Business Day.
 
                   WHAT IS THE MINIMUM REQUIRED INVESTMENT?
 
  The minimum initial investment by fiduciary and discretionary accounts of
institutions and institutional investors for Class Y Shares of the Fund is
$500,000. Other types of investors are not subject to any minimum required
investment.

                            Account No.:
 
   Note that banks may charge fees for transmitting wires.
 
  . AUTOMATIC INVESTMENT PLAN ("AIP"). Under the AIP you may arrange for
    periodic investments in the Fund through automatic deductions from a
    checking or savings account. To enroll in the AIP you should complete the
    AIP Application Form or call the Fund at (800) 438-5789. The minimum pre-
    authorized investment amount is $50. You may discontinue the AIP at any
    time. We may discontinue the AIP on 30 days' written notice to you.
 
  The Transfer Agent will send you confirmations of the opening of an account
and of all subsequent purchases, exchanges or redemptions in the account. If
your account has been set up by a broker or other investment professional,
account activity will be detailed in their statements to you.
 
  We do not issue share certificates. We reserve the right to (i) reject any
purchase order if, in our opinion, it is in the Fund's best interest to do so
and (ii) suspend the offering of shares of any Class for any period of time.
You may pay for shares of the Fund with securities which the Fund is allowed
to hold.

funds of the Trust, the Company or Framlington based on their relative net
asset values.
 
  You must meet the minimum purchase requirements for the fund of the Trust,
the Company or Framlington that you purchase by exchange. Please note that a
share exchange is a taxable event and accordingly, you may realize a taxable
gain or loss. Before making an exchange request, read the Prospectus of the
fund you wish to purchase by exchange. You can obtain a Prospectus for any
fund of the Trust, the Company or Framlington by contacting your broker or the
Funds at (800) 438-5789. Brokers may charge a fee for handling exchanges.
 
  We may modify or terminate the exchange privilege at any time. You will be
given notice of any material modifications except where notice is not
required.
 
                             REDEMPTIONS OF SHARES
 
                 WHAT PRICE DO I RECEIVE FOR REDEEMED SHARES?
 
  The redemption price is the NAV next determined after we receive the
redemption request in proper form.
 
                           WHEN CAN I REDEEM SHARES?
 
  You can redeem shares on any Business Day, provided all required documents
have been received by the Transfer Agent. The Fund may temporarily stop
redeeming shares when the NYSE is closed or trading on the NYSE is restricted,
when an emergency exists and the Fund cannot sell its assets or accurately
determine the value of its assets or if the SEC orders the Fund to suspend
redemptions.
 
                                      12
<PAGE>
 
                           HOW CAN I REDEEM SHARES?
 
  Shares held by an institution on behalf of its Customers must be redeemed in
accordance with instructions and limitations pertaining to the account at the
institution.
     
  . INVOLUNTARY REDEMPTION. We may redeem your account if its value falls
    below $250 as a result of redemptions (but not as a result of a decline
    in NAV). You will be notified in writing and allowed 60 days to increase
    the value of your account to the minimum investment level.     
 
                    WHEN WILL I RECEIVE REDEMPTION AMOUNTS?
 
  If we receive a redemption order for the Fund before 4:00 p.m. (Eastern
time) on a Business Day, we will normally wire payment to the redeeming
institution on the next Business Day. We may delay wiring redemption proceeds
for up to seven days if we feel an earlier payment would have a negative
impact on the Fund.
 
                     STRUCTURE AND MANAGEMENT OF THE FUND
 
                          HOW IS THE FUND STRUCTURED?
 
  The Trust is an open-end management investment company, which is a mutual
fund that sells and redeems shares every day that it is open for business. The
Trust is managed under the direction of its Board of Trustees which is
responsible for the overall management of the Trust and supervises the Fund's
service providers. The Trust is organized as a Massachusetts business trust.
 
                      WHO MANAGES AND SERVICES THE FUND?
   
  INVESTMENT ADVISOR. The Fund's investment advisor is Munder Capital
Management, a Delaware general partnership with its principal offices at 480
Pierce Street, Birmingham, Michigan 48009. The principal partners of the
Advisor are MCM, Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM Holdings
II, Inc. ("WAM II"). MCM was founded in April, 1985 as a Delaware corporation
and was a registered investment advisor. WAM and WAM II are Delaware
corporations and are indirect, wholly-owned subsidiaries of Comerica
Incorporated, a Michigan banking corporation, which owns or controls
approximately 88% of the partnership interests in the Advisor. As of June 30,
1998, the Advisor and its affiliates had approximately $48.2 billion in assets
under management, of which $25.4 billion were invested in equity securities,
$8.1 billion were invested in money market or other short-term instruments,
$9.2 billion were invested in other fixed income securities and $5.5 billion
in non-discretionary assets.     
   
  The Advisor provides overall investment management and research and credit
analysis for the Fund and is responsible for all purchases and sales of
portfolio securities for the Fund.     
 
  During the fiscal year ended June 30, 1998, the Advisor was paid an advisory
fee at an annual rate of .07% of the average daily net assets of the Fund
(after waivers and/or expense reimbursements). The Advisor waived advisory
fees during the past fiscal year for the Fund. The Advisor is entitled to
receive an annual fee equal to .20% of the first $250 million of the Fund's
average daily net assets, .12% of the next $250 million of the Fund's average
daily net assets and .07% of the Fund's average daily net assets over $500
million.
   
  The Advisor may, from time to time, make payments to banks, broker-dealers
or other financial institutions for certain services to the Fund and/or its
shareholders, including sub-administration, sub-transfer agency and
shareholder servicing. The Advisor may make such payments out of its own
resources and there are no additional costs to the Fund or its shareholders.
    
  The Advisor selects broker-dealers to execute portfolio transactions for the
Fund based on best price and execution terms. The Advisor may consider as a
factor the number of shares sold by the broker-dealer.

  TRANSFER AGENT. First Data Investor Services Group, Inc. is the Fund's
transfer agent. The Transfer Agent is a wholly-owned subsidiary of First Data
Corporation and is located at 4400 Computer Drive, Westborough, Massachusetts,
01581-5120.     
 
  ADMINISTRATOR. State Street Bank and Trust Company ("State Street" or
"Administrator") is the Fund's administrator. State Street is located at 225
Franklin Street, Boston, Massachusetts 02110. State Street generally assists
the Trust in all aspects of its administration and operations including
overseeing the maintenance of financial records and fund accounting. As
compensation for its services, State Street is entitled to receive fees, based
on the aggregate daily net assets of the Fund and certain other investment
portfolios that are advised by the Advisor for which it provides services,
computed daily and payable monthly at the annual rate of 0.113% on the first
$2.8 billion of net assets, plus 0.103% on the next $2.2 billion of net
assets, plus 0.101% on the next $2.5 billion of net assets, plus 0.095% on the
next $2.5 billion of net assets, plus 0.080% on the next $2.5 billion of net
assets, plus 0.070% on all net assets in excess of $12.5 billion (with a
$75,000 minimum fee per annum in the aggregate for all portfolios with respect
to the Administrator).
 
  State Street has entered into a Sub-Administration Agreement with the
Distributor under which the Distributor provides certain administrative
services with respect to the Fund. State Street pays the Distributor a fee for
these services out of its own resources at no cost to the Fund.
 
  CUSTODIAN AND SUB-CUSTODIAN. Comerica Bank ("Comerica" or the "Custodian"),
whose principal business address is One Detroit Center, 500 Woodward Avenue,
Detroit, Michigan 48226, is the Fund's custodian. No compensation is paid to
the Custodian for its custodial services. Comerica receives a fee of 0.01% of
the aggregate average daily net assets of the Fund beneficially owned by
Comerica and its customers for certain shareholder services provided by
Comerica to the Fund. State Street serves as the Fund's sub-custodian.
 
  DISTRIBUTOR. Funds Distributor, Inc. is the distributor of the Fund's shares
and is located at 60 State Street, Boston, Massachusetts 02109. It markets and
sells the Fund's shares.
 
  For an additional description of the services performed by the
Administrator, the Transfer Agent, the Custodian, the Sub-Custodian and the
Distributor, see the SAI.
   
  YEAR 2000. The Fund's operations depend on the seamless functioning of
computer systems in the financial service industry, including those of its
service providers. Many computer software systems in use today cannot properly
process date-related information after December 31, 1999 because of the method
by which dates are encoded and calculated. This failure, commonly referred to
as the "Year 2000 Issue," could adversely affect the handling of securities
trades, pricing and account servicing for the Fund. The Fund has been informed
that its major service providers have made compliance with the Year 2000 Issue
a high priority and are taking steps that they believe are reasonably designed
to address the Year 2000 Issue with respect to their computer systems. There
can be, however, no assurance that these steps will be successful, or that
interaction with other non-complying computer systems will not impair their
services at that time.     
 
                     WHAT ARE MY RIGHTS AS A SHAREHOLDER?
   
  All shareholders have equal voting, liquidation and other rights. You are
entitled to one vote for each share you hold and a fractional vote for each
fraction of a share you hold. You will be asked to vote on matters affecting
the Trust as a whole and affecting the Fund. You will not vote by class unless
expressly required by law or when the Trustees determine the matter to be
voted on affects only the interests of the holders of a particular class of
shares. The Trust will not hold annual shareholder meetings, but special
meetings may be held at the written request of shareholders owning more than
10% of outstanding shares for the purpose of removing a Trustee. Under
Massachusetts law, it is possible that a shareholder may be personally liable
for the Trust's obligations. If a shareholder were required to pay a debt of
the Fund, however, the Trust has committed to reimburse the shareholder in
full from its assets. The SAI contains more information regarding voting
rights.     
 
  Comerica currently has the right to vote a majority of the outstanding
shares of the Fund as agent, custodian or trustee for its customers and
therefore it is considered to be a controlling person of the Trust.

                      DIVIDENDS, DISTRIBUTIONS AND TAXES
 
               WHEN WILL I RECEIVE DISTRIBUTIONS FROM THE FUND?
 
  As a shareholder, you are entitled to your share of net income and capital
gains, if any, on the Fund's investments. The Fund passes its earnings along
to investors in the form of dividends. Dividend distributions are the
dividends or interest earned on investments after expenses. The net income of
the Fund, if any, is paid quarterly as a dividend. The Fund distributes its
net realized capital gains (including net short-term capital gains), if any,
at least annually.
   
  It is possible that a Fund may make a distribution in excess of the Fund's
current and accumulated earnings and profits. You will treat such a
distribution as a return of capital which is applied against and reduces your
basis in your shares. You will treat the excess of any such distribution over
your basis in your shares as gain from a sale or exchange of the shares.     
 
                        HOW WILL DISTRIBUTIONS BE MADE?
 
  The Fund will pay dividend and capital gains distributions in additional
shares of the same class of the Fund. If you wish to receive distributions in
cash, either indicate this request on your Account Application Form or notify
the Fund at (800) 438-5789.
 
           ARE THERE TAX IMPLICATIONS OF MY INVESTMENTS IN THE FUND?
   
  This section contains a brief summary of the tax implications of ownership
in the Fund's shares. A more detailed discussion about the tax treatment of
distributions from the Fund and about other potential tax liabilities,
including backup withholding for certain taxpayers, and about tax aspects of
dispositions of shares of the Fund, is contained in the SAI. You should
consult your tax advisor regarding the impact of owning the Fund's shares on
your own personal tax situation including the applicability of any state and
local taxes.     
   
  In general, as long as the Fund meets the requirements to qualify as a
regulated investment company ("RIC") under Federal tax laws, it will not be
subject to Federal income tax on its income and capital gains that it
distributes in a timely manner to its shareholders. The Fund intends to
qualify annually as a RIC. Even if it qualifies as a RIC, the Fund may still
be liable for any excise tax on income that is not distributed in accordance
with a calendar year requirement; the Fund intends to avoid the excise tax by
making timely distributions.     
 
  Generally, you will owe tax on the amounts distributed to you, regardless of
whether you receive these amounts in cash or reinvest them in additional Fund
shares. Shareholders not subject to tax on their income generally will not be
required to pay any tax on amounts distributed to them. Federal income tax on
distributions to an IRA or to a qualified retirement plan will generally be
deferred.
 
  Capital gains derived from sales of portfolio securities held by the Fund
will generally be designated as long-term or short-term. Distributions from
the Fund's long-term capital gains are generally taxed at the long-term
capital gains rate regardless of how long you have owned shares in the Fund.
Dividends from other sources are generally taxed as ordinary income.
 
  Dividends and capital gain distributions are generally taxable when you
receive them; however, if a distribution is declared in October, November or
December, but not paid until January of the following year, it will be
considered to be paid on December 31 in the year in which it was declared.
Shortly after the end of each year, you will receive from the Fund a statement
of the amount and nature of the distributions made to you during the year.
 
  If you redeem, transfer or exchange Fund shares, you may have taxable gain
or a loss. If you hold Fund shares for six months or less, and during that
time you receive a capital gain dividend, any loss you realize on the sale of
these Fund shares will be treated as a long-term loss to the extent of the
earlier distribution.
 
                                      15

  Dividends and certain interest income earned from foreign securities by the
Fund may be subject to foreign withholding or other taxes. The Fund may be
permitted to pass on to its shareholders the right to a credit or deduction
for income or other tax credits earned from foreign investments and it intends
to do so if possible. These deductions or credits may be subject to tax law
limitations.
 
  If the Fund invests in certain "passive foreign investment companies"
("PFICs"), it will be subject to Federal income tax (and possibly additional
interest charges) on a portion of any "excess distribution" or gain from the
disposition of such shares, even if it distributes such income to its
shareholders. If the Fund elects to treat a PFIC as a "qualified electing
fund" ("QEF") and the PFIC furnishes certain financial information in the
required form to the Fund, the Fund will instead be required to include in
income each year its allocable share of the ordinary earnings and net capital
gains of the QEF, regardless of whether received, and such amounts will be
subject to the various distribution requirements described above. The Fund may
also elect to mitigate the tax effects of owning PFIC stock by making an
annual mark-to-market election with respect to PFIC shares.
 
                            ADDITIONAL INFORMATION
 
  SHAREHOLDER COMMUNICATIONS. You will receive unaudited Semi-Annual Reports
and audited Annual Reports on a regular basis from the Fund. In addition, you
will also receive updated Prospectuses or Supplements to this Prospectus. In
order to eliminate duplicate mailings, the Fund will only send one copy of the
above communications to (1) accounts with the same primary record owner, (2)
joint tenant accounts, (3) tenant in common accounts and (4) accounts which
have the same address.

     The Trust was organized on August 30, 1989 under the name "PDB Fund," which
was changed in November 1989 to "Opportunity Funds," in February 1990 to
"Ambassador Funds" and in June 1995 to "The Munder Funds Trust." The Tax-Free
Intermediate Bond Fund originally commenced operations on February 9, 1987 as a
separate portfolio of the St. Clair Tax-Free Fund, Inc.  On November 20, 1992,
the St. Clair Tax-Free Intermediate Bond Fund was reorganized as the Ambassador
Tax-Free Intermediate Bond Fund.  The Company was organized as a Maryland
corporation on November 18, 1992.  Framlington was organized as a Massachusetts
business trust on October 30, 1996.
    
     As stated in each Prospectus, the investment advisor of each Fund is Munder
Capital Management (the "Advisor").  The principal partners of the Advisor are
Old MCM, Inc. ("MCM"), Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM
Holdings II, Inc. ("WAM II").  MCM was founded in April 1985 as a Delaware     

                                       3
<PAGE>
     
corporation and was a registered investment advisor.  WAM and WAM II are
indirect, wholly-owned subsidiaries of Comerica Incorporated which owns or
controls approximately 88% of the partnership interests in the Advisor.

     Framlington Overseas Investment Management Limited (the "Sub-Advisor")
serves as sub-advisor for the Framlington Funds.  The Sub-Advisor is a
subsidiary of Framlington Group Limited, incorporated in England and Wales
which, through its subsidiaries, provides a wide range of investment services.
Framlington Group Limited is a wholly owned subsidiary of Framlington Holdings
Limited which is, in turn, owned 49% by the Advisor and 51% by Credit Commercial
de France S.A., a French banking corporation listed on the Societe des Bourses
Francaises.     

     Capitalized terms used in this Statement of Additional Information and not
otherwise defined have the same meanings as are given to them in each
Prospectus.

                               FUND INVESTMENTS
    
     The following supplements the information contained in each Prospectus
concerning the investment objectives and policies of the Funds.  With the
exception of the investment objectives of Multi-Season Fund, Real Estate Fund
and Money Market Fund, each Fund's investment objective is a non-fundamental
policy and may be changed without the authorization of the holders of a majority
of the Fund's outstanding shares.  The Tax-Free Bond Fund and Tax-Free Money
Market Fund each have a fundamental policy to invest at least 80% of its
respective assets in municipal obligations bearing tax-exempt interest; all
other investment policies, other than those specifically designated as
fundamental, are non-fundamental policies and may be changed without the
authorization of the holders of a majority of a Fund's outstanding shares.
There can be no assurance that a Fund will achieve its objective.  A description
of applicable credit ratings is set forth in Appendix A to this Statement of
Additional Information.  For purposes of this Statement of Additional
Information, the Equity Selection Fund, Global Financial Services Fund, Growth &
Income Fund, Growth Opportunities Fund, Index 500 Fund, International Equity
Fund, Micro-Cap Fund, Multi-Season Fund, NetNet Fund, Real Estate Fund, Small-
Cap Value Fund, Small Company Growth Fund, Value Fund, International Growth
Fund, Emerging Markets Fund and Healthcare Fund are referred to as the "Equity
Funds"; the Bond Fund, Intermediate Bond Fund and U.S. Income Fund are referred
to as the "Bond Funds"; the Michigan Bond Fund, Tax-Free Bond Fund and Tax-Free
Intermediate Bond Fund are referred to as the "Tax-Free Bond Funds" and Cash
Investment Fund, Money Market Fund, Tax-Free Money Fund and U.S. Treasury Money
Market Fund are referred to as the "Money Market Funds."

     BORROWING.  Each of the Funds is authorized to borrow money in amounts up
to 5% of the value of its total assets at the time of such borrowings for
temporary purposes, and are authorized to borrow money in excess of the 5% limit
as permitted by the Investment Company Act of 1940, as amended (the "1940 Act"),
to meet redemption requests.  This borrowing may be unsecured.  The 1940 Act
requires the Funds to maintain continuous asset coverage of 300% of the amount
borrowed.  If the 300% asset coverage should decline as a result of market
fluctuations or other reasons, the Funds may be required to sell some of their
portfolio holdings within three days to reduce the debt and restore the 300%
asset coverage, even though it may be disadvantageous from an investment
standpoint to sell securities at that time.  Borrowed funds are subject to
interest costs that may or may not be offset by amounts earned on the borrowed
funds.  A Fund may also be required to maintain minimum average balances in
connection with such borrowing or to pay a commitment or other fees to maintain
a line of credit; either of these requirements would increase the cost of
borrowing over the stated interest rate.  Each Fund may, in connection with
permissible borrowings, transfer as collateral securities owned by the Fund.    

     FOREIGN SECURITIES.  Each Equity Fund (except Global Financial Services
Fund, Real Estate Fund, International Equity Fund, International Growth Fund,
Emerging Markets Fund and Healthcare Fund), each Bond Fund, each Tax-Free Bond
Fund, the Balanced Fund, the Cash Investment Fund and the Money Market Fund may
invest up to 25% of its assets in foreign securities.  Under normal market
conditions, the International Equity Fund, International Bond Fund and
International Growth Fund will each invest at least 65% of its assets in
securities of issuers located in at least three countries other than the United
States.  The Global Financial Services Fund will invest at least 65% of its
assets in securities of issuers located in at least three countries, one of
which may be the United States.  The Emerging Markets Fund will invest at least
65% of its assets in emerging market countries.  There is no limit on the
Healthcare Fund's investments in foreign securities.  The Multi-Season Fund and
NetNet

                                       4
<PAGE>
 
Fund typically will only purchase foreign securities which are represented by
American Depositary Receipts ("ADRs") listed on a domestic securities exchange
or included in the NASDAQ National Market System, or foreign securities listed
directly on a domestic securities exchange or included in the NASDAQ National
Market System. ADRs are receipts typically issued by a United States bank or
trust company evidencing ownership of the underlying foreign securities. Certain
institutions issuing ADRs may not be sponsored by the issuer. A non-sponsored
depositary may not provide the same shareholder information that a sponsored
depositary is required to provide under its contractual arrangements with the
issuer.

         

     The International Bond Fund will primarily invest in foreign debt
obligations denominated in foreign currencies, including the European Currency
Unit ("ECU"), which are issued by foreign governments and governmental agencies,
instrumentalities or political subdivisions; debt securities issued or
guaranteed by supranational organizations (as defined below); corporate debt
securities; bank or bank holding company debt securities and other debt
securities including those convertible into foreign stock.  For the purposes of
the 65% minimum with respect to the International Bond Fund's designation as an
international bond fund, the securities described in this paragraph are
considered "international bonds."

     Income and gains on foreign securities may be subject to foreign
withholding taxes.  Investors should consider carefully the substantial risks
involved in securities of companies and governments of foreign nations, which
are in addition to the usual risks inherent in domestic investments.  There may
be less publicly available information about foreign companies comparable to the
reports and ratings published about companies in the United States.  Foreign
companies are not generally subject to uniform accounting, auditing and
financial reporting standards, and auditing practices and requirements may not
be comparable to those applicable to United States companies.  Foreign markets
have substantially less volume than the New York Stock Exchange and securities
of some foreign companies are less liquid and more volatile than securities of
comparable United States companies.  Commission rates in foreign countries,
which are generally fixed rather than subject to negotiation as in the United
States, are likely to be higher.  In many foreign countries there is less
government supervision and regulation of stock exchanges, brokers, and listed
companies than in the United States.  Such concerns are particularly heightened
for emerging markets and Eastern European countries.

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

     Investments in Eastern European countries may involve risks of
nationalization, expropriation and confiscatory taxation.  The Communist
governments of a number of Eastern European countries expropriated large amounts
of private property in the past, in many cases without adequate compensation,
and there can be no assurance that such expropriation will not occur in the
future.  In the event of such expropriation, the Fund could lose a substantial
portion of any investments it has made in the affected countries.  Further, no
accounting standards exist in Eastern European countries.  Finally, even though
certain Eastern European currencies may be convertible into United States
dollars, the conversion rates may be artificial to the actual market values and
may be adverse to a Fund.

     The Advisor (Sub-Advisor with respect to the Framlington Funds) endeavors
to buy and sell foreign currencies on as favorable a basis as practicable.  Some
price spread on currency exchange (to cover service charges) may be incurred,
particularly when the Fund changes investments from one country to another or
when proceeds of the sale of Fund shares in U.S. dollars are used for the
purchase of securities in foreign countries.  Also, some countries may adopt
policies which would prevent the Fund from transferring cash out of the country
or 

                                       5
<PAGE>
 
withhold portions of interest and dividends at the source.  There is the
possibility of expropriation, nationalization or confiscatory taxation,
withholding and other foreign taxes on income or other amounts, foreign exchange
controls (which may include suspension of the ability to transfer currency from
a given country), default in foreign government securities, political or social
instability or diplomatic developments that could affect investments in
securities of issuers in foreign nations.

     Foreign securities markets have different clearance and settlement
procedures, and in certain markets there have been times when settlements have
been unable to keep pace with the volume of securities transactions, making it
difficult to conduct such transactions.  Delays in settlement could result in
temporary periods when assets of a Fund are uninvested and no return is earned
thereon.  The inability of a Fund to make intended security purchases due to
settlement problems could cause the Fund to miss attractive investment
opportunities.  Inability to dispose of portfolio securities due to settlement
problems could result either in losses to a Fund due to subsequent declines in
value of the portfolio security or, if the fund has entered into a contract to
sell the security, could result in possible liability to the purchaser.

     A Fund may be affected either unfavorably or favorably by fluctuations in
the relative rates of exchange between the currencies of different nations, by
exchange control regulations and by indigenous economic and political
developments.  Changes in foreign currency exchange rates will influence values
within a Fund from the perspective of U.S. investors, and may also affect the
value of dividends and interest earned, gains and losses realized on the sale of
securities, and net investment income and gains, if any, to be distributed to
shareholders by a Fund.  The rate of exchange between the U.S. dollar and other
currencies is determined by the forces of supply and demand in the foreign
exchange markets.  These forces are affected by the international balance of
payments and other economic and financial conditions, government intervention,
speculation and other factors.  The Advisor (Sub-Advisor with respect to the
Framlington Fund), will attempt to avoid unfavorable consequences and to take
advantage of favorable developments in particular nations where, from time to
time, it places a Fund's investments.

     The exercise of this flexible policy may include decisions to purchase
securities with substantial risk characteristics and other decisions such as
changing the emphasis on investments from one nation to another and from one
type of security to another.  Some of these decisions may later prove profitable
and others may not.  No assurance can be given that profits, if any, will exceed
losses.

     FORWARD FOREIGN CURRENCY TRANSACTIONS.  In order to protect against a
possible loss on investments resulting from a decline or appreciation in the
value of a particular foreign currency against the U.S. dollar or another
foreign currency, the Equity Funds (excluding the Real Estate Fund), the
Balanced Fund, the Bond Funds and the International Bond Fund are authorized to
enter into forward foreign currency exchange contracts ("forward currency
contracts").  These contracts involve an obligation to purchase or sell a
specified currency at a future date at a price set at the time of the contract.
Forward currency contracts do not eliminate fluctuations in the values of
portfolio securities but rather allow a Fund to establish a rate of currency
exchange for a future point in time.

     When entering into a contract for the purchase or sale of a security, a
Fund may enter into a forward currency exchange contract for the amount of the
purchase or sale price to protect against variations, between the date the
security is purchased or sold and the date on which payment is made or received,
in the value of the foreign currency relative to the U.S. dollar or other
foreign currency.

     When the Advisor (Sub-Advisor with respect to the Framlington Funds)
anticipates that a particular foreign currency may decline substantially
relative to the U.S. dollar or other leading currencies, in order to reduce
risk, a Fund may enter into a forward contract to sell, for a fixed amount, the
amount of foreign currency approximating the value of some or all of the Fund's
securities denominated in such foreign currency.  Similarly, when the
obligations held by a Fund create a short position in a foreign currency, the
Fund may enter into a forward contract to buy, for a fixed amount, an amount of
foreign currency approximating the short position.  With respect to any forward
currency contract, it will not generally be possible to match precisely the
amount covered by that contract and the value of the securities involved due to
the changes in the values of such securities resulting from market movements
between the date the forward contract is entered into and the date it matures.
In addition, while forward contracts may offer protection from losses resulting
from declines or appreciation in the value of a particular foreign 

                                       6
<PAGE>
 
currency, they also limit potential gains which might result from changes in the
value of such currency. A Fund will also incur costs in connection with forward
currency contracts and conversions of foreign currencies and U.S. dollars.
    
     Cash or liquid securities equal to the amount of a Fund's assets that could
be required to consummate forward contracts will be designated on the records of
the Fund or the Funds' sub-custodian except to the extent the contracts are
otherwise "covered."  For the purpose of determining the adequacy of the
designated securities, the designated securities will be valued at market or
fair value.  If the market or fair value of such securities declines, additional
cash or securities will be designated daily so that the value of the designated
securities will equal the amount of such commitments by the Fund.  A forward
contract to sell a foreign currency is "covered" if a Fund owns the currency (or
securities denominated in the currency) underlying the contract, or holds a
forward contract (or call option) permitting the Fund to buy the same currency
at a price no higher than the Fund's price to sell the currency.  A forward
contract to buy a foreign currency is "covered" if a Fund holds a forward
contract (or put option) permitting the Fund to sell the same currency at a
price as high as or higher than the Fund's price to buy the currency.      

     FUTURES CONTRACTS AND RELATED OPTIONS.  The Equity Funds, the Balanced
Fund, the Bond Funds, the Tax-Free Bond Funds and the International Bond Fund
may purchase and sell futures contracts on interest-bearing securities or
securities indices, and may purchase and sell call and put options on futures
contracts.  For a detailed description of futures contracts and related options,
see Appendix B to this Statement of Additional Information.
    
     ILLIQUID SECURITIES. The Equity Funds, Balanced Fund, Tax-Free Bond Funds,
International Bond Fund and the Bond Funds may invest up to 15%, and each of the
Money Market Funds may invest up to 10%, of the value of its net assets
(determined at time of acquisition) in securities that are illiquid. Illiquid
securities would generally include securities for which there is a limited
trading market, repurchase agreements and time deposits with notice/termination
dates in excess of seven days, and certain securities that are subject to
trading restrictions because they are not registered under the Securities Act of
1933, as amended (the "Act"). If, after the time of acquisition, events cause
this limit to be exceeded, the Fund will take steps to reduce the aggregate
amount of illiquid securities as soon as reasonably practicable in accordance
with the policies of the SEC.     

     Each Fund (except U.S. Treasury Money Market Fund and Short Term Treasury
Fund) may invest in commercial obligations issued in reliance on the "private
placement" exemption from registration afforded by Section 4(2) of the Act
("Section 4(2) paper").  A Fund may also purchase securities that are not
registered under the Act, but which can be sold to qualified institutional
buyers in accordance with Rule 144A under the Act, ("Rule 144A securities").
Section 4(2) paper is restricted as to disposition under the Federal securities
laws, and generally is sold to institutional investors who agree that they are
purchasing the paper for investment and not with a view to public distribution.
Any resale by the purchaser must be in an exempt transaction.  Section 4(2)
paper normally is resold to other institutional investors through or with the
assistance of the issuer or investment dealers which make a market in the
Section 4(2) paper, thus providing liquidity.  Rule 144A securities generally
must be sold only to other qualified institutional buyers.  If a particular
investment in Section 4(2) paper or Rule 144A securities is not determined to be
liquid, that investment will be included within the Fund's limitation on
investment in illiquid securities.  The Advisor will determine the liquidity of
such investments pursuant to guidelines established by the Boards of
Directors/Trustees.  It is possible that unregistered securities purchased by
the Fund in reliance upon Rule 144A could have the effect of increasing the
level of the Fund's illiquidity to the extent that qualified institutional
buyers become, for a period, uninterested in purchasing these securities.
    
     INTEREST RATE SWAP TRANSACTIONS.  Each of the Bond Funds and the
International Bond Fund may enter into interest rate swap agreements for
purposes of attempting to obtain a particular desired return at a lower cost to
the Funds than if the Funds had invested directly in an instrument that yielded
that desired return.  Interest rate swap transactions involve the exchange by a
Fund with another party of its commitments to pay or receive interest, such as
an exchange of fixed rate payments for floating rate payments.  Typically, the
parties with which the Funds will enter into interest rate swap transactions
will be brokers, dealers or other financial institutions known as
"counterparties." Certain Federal income tax requirements may, however, limit
the Funds' ability to engage in      

                                       7
<PAGE>

     
certain interest rate transactions. Gains from transaction in interest rate
swaps distributed to shareholders of the Funds will be taxable as ordinary
income or, in certain circumstances, as long-term capital gains to the
shareholders.

     Each of the Funds' 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").  Each of the Funds' obligations under a swap
agreement will be accrued daily (offset against any amounts owed to the Fund).
Accrued but unpaid net amounts owed to a swap counterparty will be covered by
earmarking cash, U.S. Government securities or other high-grade liquid
securities on the books of the Fund or the Fund's sub-custodian, to avoid any
potential leveraging of a Fund's portfolio.

     The Funds will not enter into any interest rate swap transaction unless the
credit quality of the unsecured senior debt or the claims-paying ability of the
other party to the transaction is rated in one of the highest four rating
categories by at least one nationally-recognized statistical rating organization
("NRSRO") or is believed by the Advisor to be equivalent to that rating.  If the
other party to a transaction defaults, the Funds will have contractual remedies
pursuant to the agreements related to the transactions.

     The use of interest rate swaps is a highly specialized activity that
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions.  If the Advisor is incorrect in its
forecasts of market values, interest rates and other applicable factors, the
investment performance of each of the Funds would be lower than it would have
been if interest rate swaps were not used.  The swaps market has grown
substantially in recent years with a large number of banks and investment
banking firms acting both as principals and as agents utilizing standardized
swap documentation.  As a result, the swaps market has become relatively liquid
in comparison with other similar instruments traded in the interbank market.
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 the Funds' ability to terminate existing swap
agreements or to realize amounts to be received under such agreements.

     INVESTMENT COMPANY SECURITIES.  Each of the Funds (other than the Short
Term Treasury Fund) may invest in securities issued by other investment
companies.  As a shareholder of another investment company, a Fund would bear
its pro rata portion of the other investment company's expenses, including
advisory fees.  These expenses would be in addition to the expenses each Fund
bears directly in connection with its own operations.  Each Fund currently
intends to limit its investments in securities issued by other investment
companies so that, as determined immediately after a purchase of such securities
is made: (i) not more than 5% of the value of the Fund's total assets will be
invested in the securities of any one investment company; (ii) not more than 10%
of the value of its total assets will be invested in the aggregate in securities
of investment companies as a group; and (iii) not more than 3% of the
outstanding voting stock of any one investment company will be owned by the
Fund.      

     LENDING OF PORTFOLIO SECURITIES.  To enhance the return on its portfolio,
each of the Funds may lend securities in its portfolio (subject to a limit of
25% of each Fund's, other than the Money Market Fund's, total assets; and 
33 1/3% of the Money Market Fund's total assets) to securities firms and 
financial institutions, provided that each loan is secured continuously by
collateral in the form of cash, high quality money market instruments or short-
term U.S. Government securities adjusted daily to have a market value at least
equal to the current market value of the securities loaned. These loans are
terminable at any time, and the Funds will receive any interest or dividends
paid on the loaned securities. In addition, it is anticipated that a Fund may
share with the borrower some of the income received on the collateral for the
loan or the Fund will be paid a premium for the loan. The risk in lending
portfolio securities, as with other extensions of credit, consists of possible
delay in recovery of the securities or possible loss of rights in the collateral
should the borrower fail financially. In determining whether the Funds will lend
securities, the Advisor (Sub-Advisor with respect to the Framlington Funds) will
consider all relevant facts and circumstances. The Funds will only enter into
loan arrangements with broker-dealers, banks or other institutions which the
Advisor (Sub-Advisor with respect to the Framlington Funds) has determined are
creditworthy under guidelines established by the Boards of Directors/Trustees.

     LOWER-RATED DEBT SECURITIES.  It is expected that each Fund (other than the
Money Market Funds, Index 500 Fund and Growth & Income Fund) will invest not
more than 5% of its total assets in securities that are rated

                                       8
<PAGE>

     
below investment grade by Standard & Poor's Rating Service, a division of 
McGraw-Hill Companies, Inc. ("S&P"), or Moody's Investors Service, Inc.
("Moody's"), or in comparable unrated securities. The Growth & Income Fund may
invest up to 20% of the value of its total assets in such securities. The Money
Market Funds and the Index 500 Fund may not invest in such securities. Such
securities are also known as junk bonds. The yields on lower-rated debt and
comparable unrated securities generally are higher than the yields available on
higher-rated securities. However, investments in lower-rated debt and comparable
unrated securities generally involve greater volatility of price and risk of
loss of income and principal, including the possibility of default by or
bankruptcy of the issuers of such securities. Lower-rated debt and comparable
unrated securities (a) will likely have some quality and protective
characteristics that, in the judgment of the rating organization, are outweighed
by large uncertainties or major risk exposures to adverse conditions and (b) are
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. Accordingly,
it is possible that these types of factors could, in certain instances, reduce
the value of securities held in each Fund's portfolio, with a commensurate
effect on the value of each of the Fund's shares. Therefore, an investment in
the Funds should not be considered as a complete investment program and may not
be appropriate for all investors.      

     While the market values of lower-rated debt and comparable unrated
securities tend to react more to fluctuations in interest rate levels than the
market values of higher-rated securities, the market values of certain lower
rated debt and comparable unrated securities also tend to be more sensitive to
individual corporate developments and changes in economic conditions than
higher-rated securities.  In addition, lower-rated debt securities and
comparable unrated securities generally present a higher degree of credit risk.
Issuers of lower-rated debt and comparable unrated securities often are highly
leveraged and may not have more traditional methods of financing available to
them so that their ability to service their debt obligations during an economic
downturn or during sustained periods of rising interest rates may be impaired.
The risk of loss due to default by such issuers is significantly greater because
lower-rated debt and comparable unrated securities generally are unsecured and
frequently are subordinated to the prior payment of senior indebtedness.  The
Funds may incur additional expenses to the extent that they are required to seek
recovery upon a default in the payment of principal or interest on their
portfolio holdings.  The existence of limited markets for lower-rated debt and
comparable unrated securities may diminish each of the Fund's ability to (a)
obtain accurate market quotations for purposes of valuing such securities and
calculating its net asset value and (b) sell the securities at fair value either
to meet redemption requests or to respond to changes in the economy or in
financial markets.
    
     Lower-rated debt securities and comparable unrated securities may have call
or buy-back features that permit their issuers to call or repurchase the
securities from their holders.  If an issuer exercises these rights during
periods of declining interest rates, the Funds may have to replace the security
with a lower yielding security, thus resulting in a decreased return to the
Funds.  A description of applicable credit ratings is set forth in Appendix A of
this Statement of Additional Information.

     MONEY MARKET INSTRUMENTS. As described in the Prospectuses, each of the
Funds (except the Short Term Treasury Fund) may invest from time to time in
"money market instruments," a term that includes, among other things, bank
obligations, commercial paper, variable amount master demand notes and corporate
bonds with remaining maturities of 397 days or less.     

     Bank obligations include bankers' acceptances, negotiable certificates of
deposit and non-negotiable time deposits, including U.S. dollar-denominated
instruments issued or supported by the credit of U.S. or foreign banks or
savings institutions.  Although the Funds will invest in obligations of foreign
banks or foreign branches of U.S. banks only where the Advisor (Sub-Advisor with
respect to the Framlington Funds) deems the instrument to present minimal credit
risks, such investments may nevertheless entail risks that are different from
those of investments in domestic obligations of U.S. banks due to differences in
political, regulatory and economic systems and conditions.  All investments in
bank obligations are limited to the obligations of financial institutions having
more than $1 billion in total assets at the time of purchase.
    
     Investments by a Fund in commercial paper will consist of issues rated at
the time of purchase A-1 and/or P-1 by  S&P or Moody's.  In addition, the Funds
may acquire unrated commercial paper and corporate bonds that      

                                       9
<PAGE>

     
are determined by the Advisor (Sub-Advisor with respect to the Framlington
Funds) at the time of purchase to be of comparable quality to rated instruments
that may be acquired by such Fund as previously described.

     The Funds may also purchase variable amount master demand notes which are
unsecured instruments that permit the indebtedness thereunder to vary and
provide for periodic adjustments in the interest rate.  Although the notes are
not normally traded and there may be no secondary market in the notes, a Fund
may demand payment of the principal of the instrument at any time.  The notes
are not typically rated by credit rating agencies, but issuers of variable
amount master demand notes must satisfy the same criteria as set forth above for
issuers of commercial paper.  If an issuer of a variable amount master demand
note defaulted on its payment obligation, a Fund might be unable to dispose of
the note because of the absence of a secondary market and might, for this or
other reasons, suffer a loss to the extent of the default.  The Funds invest in
variable amount master notes only when the Advisor (Sub-Advisor with respect to
the Framlington Funds) deems the investment to involve minimal credit risk.

     MORTGAGE-RELATED SECURITIES.  There are a number of important differences
among the agencies and instrumentalities of the U.S. Government that issue
mortgage-related securities and among the securities that they issue.  Mortgage-
related securities guaranteed by the Government National Mortgage Association
("GNMA") include GNMA Mortgage Pass-Through Certificates (also known as "Ginnie
Maes") which are guaranteed as to the timely payment of principal and interest
by GNMA and such guarantee is backed by the full faith and credit of the United
States.  GNMA is a wholly-owned U.S. Government corporation within the
Department of Housing and Urban Development.  GNMA certificates also are
supported by the authority of GNMA to borrow funds from the U.S. Treasury to
make payments under its guarantee.  Mortgage-related securities issued by the
Federal National Mortgage Association ("FNMA") include FNMA Guaranteed Mortgage
Pass-Through Certificates (also known as "Fannie Maes") which are solely the
obligations of the FNMA and are not backed by or entitled to the full faith and
credit of the United States, but are supported by the right of the issuer to
borrow from the U.S. Treasury.  FNMA is a government-sponsored organization
owned entirely by private stockholders.  Fannie Maes are guaranteed as to timely
payment of the principal and interest by FNMA. Mortgage-related securities
issued by the Federal Home Loan Mortgage Corporation ("FHLMC") include FHLMC
Mortgage Participation Certificates (also known as "Freddie Macs" or "PCs").
FHLMC is a corporate instrumentality of the United States, created pursuant to
an Act of Congress, which is owned entirely by Federal Home Loan Banks.  Freddie
Macs are not guaranteed by the United States or by any Federal Home Loan Banks
and do not constitute a debt or obligation of the United States or of any
Federal Home Loan Bank.  Freddie Macs entitle the holder to timely payment of
interest, which is guaranteed by the FHLMC.  FHLMC guarantees either ultimate
collection or timely payment of all principal payments on the underlying
mortgage loans.  When FHLMC does not guarantee timely payment of principal,
FHLMC may remit the amount due on account of its guarantee of ultimate payment
of principal at any time after default on an underlying mortgage, but in no
event later than one year after it becomes payable.      

     MUNICIPAL OBLIGATIONS.  Opinions relating to the validity of municipal
obligations and to the exemption of interest thereon from regular Federal income
tax are rendered by bond counsel or counsel to the respective issuers at the
time of issuance.  Neither the Trust nor the Advisor will review the proceedings
relating to the issuance of municipal obligations or the bases for such
opinions.

     An issuer's obligations under its municipal obligations are subject to the
provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of creditors, such as the Federal Bankruptcy Code, and laws, if any,
which may be enacted by Federal or state legislatures extending the time for
payment of principal or interest, or both, or imposing other constraints upon
enforcement of such obligations or upon the ability of municipalities to levy
taxes.  The power or ability of an issuer to meet its obligations for the
payment of interest on and principal of its municipal obligations may be
materially adversely affected by litigation or other conditions.

     From time to time proposals have been introduced before Congress for the
purpose of restricting or eliminating the Federal income tax exemption for
interest on municipal obligations.  For example, under the Tax Reform Act of
1986 interest on certain private activity bonds must be included in an
investor's Federal alternative minimum taxable income, and corporate investors
must include all tax-exempt interest in their Federal alternative minimum
taxable income.  The Trust cannot predict what legislation, if any, may be
proposed in Congress in the future as regards the Federal income tax status of
interest on municipal obligations in general, or which proposals, if 

                                       10
<PAGE>
 
any, might be enacted. Such proposals, if enacted, might materially adversely
affect the availability of municipal obligations for investment by the Tax-Free
Bond Funds and the Tax-Free Money Market Fund and the liquidity and value of
such Funds. In such an event the Board of Trustees would reevaluate the Fund's
investment objective and policies and consider changes in its structure or
possible dissolution.

     The Cash Investment Fund and the Money Market Fund each may, when deemed
appropriate by the Advisor in light of the Fund's investment objective, invest
in high quality municipal obligations issued by state and local governmental
issuers, the interest on which may be taxable or tax-exempt for Federal income
tax purposes, provided that such obligations carry yields that are competitive
with those of other types of money market instruments of comparable quality.
The Cash Investment Fund and the Money Market Fund each do not expect to invest
more than 5% of its net assets in such municipal obligations during the current
fiscal year.

     NON-DOMESTIC BANK OBLIGATIONS.  Non-domestic bank obligations include
Eurodollar Certificates of Deposit ("ECDs"), which are U.S. dollar-denominated
certificates of deposit issued by offices of foreign and domestic banks located
outside the United States; Eurodollar Time Deposits ("ETDs"), which are U.S.
dollar-denominated deposits in a foreign branch of a U.S. bank or a foreign
bank; Canadian Time Deposits ("CTDs"), which are essentially the same as ETDs
except they are issued by Canadian offices of major Canadian banks; Schedule Bs,
which are obligations issued by Canadian branches of foreign or domestic banks;
Yankee Certificates of Deposit ("Yankee CDs"), which are U.S. dollar-denominated
certificates of deposit issued by a U.S. branch of a foreign bank and held in
the United States; and Yankee Bankers' Acceptances ("Yankee BAs"), which are
U.S. dollar denominated bankers' acceptances issued by a U.S. branch of a
foreign bank and held in the United States.
    
     OPTIONS.  Each of the Equity Funds, Balanced Fund, Bond Funds,
International Bond Fund and Tax-Free Bond Funds (other than Tax-Free
Intermediate Bond Fund) may write covered call options, buy put options, buy
call options and write secured put options.  Such options may relate to
particular securities and may or may not be listed on a national securities
exchange and issued by the Options Clearing Corporation.  Options trading is a
highly specialized activity which entails greater than ordinary investment risk.
Options on particular securities may be more volatile than the underlying
securities, and therefore, on a percentage basis, an investment in options may
be subject to greater fluctuation than an investment in the underlying
securities themselves.  For risks associated with options on foreign currencies,
see Appendix B to this Statement of Additional Information.

     A call option for a particular security gives the purchaser of the option
the right to buy, and the writer of the option the obligation to sell, the
underlying security at the stated exercise price at any time prior to the
expiration of the option, regardless of the market price of the security.  The
premium paid to the writer is in consideration for undertaking the obligations
under the option contract.  A put option for a particular security gives the
purchaser the right to sell, and the writer of the option the obligation to buy,
the underlying security at the stated exercise price at any time prior to the
expiration date of the option, regardless of the market price of the security.

     The writer of an option that wishes to terminate its obligation may effect
a "closing purchase transaction." This is accomplished by buying an option of
the same series as the option previously written.  The effect of the purchase is
that the writer's position will be canceled by the clearing corporation.
However, a writer may not effect a closing purchase transaction after being
notified of the exercise of an option.  Likewise, an investor who is the holder
of an option may liquidate its position by effecting a "closing sale
transaction." The cost of such a closing purchase plus transaction costs may be
greater than the premium received upon the original option, in which event the
Fund will have incurred a loss in the transaction.  There is no guarantee that
either a closing purchase or a closing sale transaction can be effected.      

     Effecting a closing transaction in the case of a written call option will
permit the Funds to write another call option on the underlying security with
either a different exercise price or expiration date or both, or in the case of
a written put option, will permit the Funds to write another put option to the
extent that the exercise price thereof is secured by deposited cash or short-
term securities.  Also, effecting a closing transaction will permit the cash or
proceeds from the concurrent sale of any securities subject to the option to be
used for other Fund investments.  If a Fund desires to sell a particular
security from its portfolio on which it has written a call option, it will
effect a closing transaction prior to or concurrent with the sale of the
security.

                                       11
<PAGE>

     
     The Funds may write options in connection with buy-and-write transactions;
that is, the Funds may purchase a security and then write a call option against
that security.  The exercise price of the call the Funds determine to write will
depend upon the expected price movement of the underlying security.  The
exercise price of a call option may be below ("in-the-money"), equal to ("at-
the-money") or above ("out-of-the-money") the current value of the underlying
security at the time the option is written.  Buy-and-write transactions using
in-the-money call options may be used when it is expected that the price of the
underlying security will remain flat or decline moderately during the option
period.  Buy-and-write transactions using out-of-the-money call options may be
used when it is expected that the premiums received from writing the call option
plus the appreciation in the market price of the underlying security up to the
exercise price will be greater than the appreciation in the price of the
underlying security alone.  If the call options are exercised in such
transactions, the maximum gain to the relevant Fund will be the premium received
by it for writing the option, adjusted upwards or downwards by the difference
between the Fund's purchase price of the security and the exercise price.  If
the options are not exercised and the price of the underlying security declines,
the amount of such decline will be offset in part, or entirely, by the premium
received.

     In the case of a call option on a security, the option is "covered" if a
Fund owns the security underlying the call or has an absolute and immediate
right to acquire that security without additional cash consideration (or, if
additional cash consideration is required, cash or liquid securities in such
amount as are earmarked on the books of the Fund or the Fund's sub-custodian)
upon conversion or exchange of other securities held by it.  For a call option
on an index, the option is covered if a Fund maintains with its sub-custodian
cash or liquid securities equal to the contract value.  A call option is also
covered if a Fund holds a call on the same security or index as the call written
where the exercise price of the call held is (i) equal to or less than the
exercise price of the call written, or (ii) greater than the exercise price of
the call written provided the difference in cash or liquid securities is
earmarked on the books of the Fund or the Fund's sub-custodian.  A Fund will
limit its investment in uncovered call options purchased or written by the Fund
to 33 1/3% of the Fund's total assets.  A Fund will write put options only if
they are "secured" by cash or liquid securities earmarked on the books of the
Fund or the Fund's sub-custodian in an amount not less than the exercise price
of the option at all times during the option period.      

     The writing of covered put options is similar in terms of risk/return
characteristics to buy-and-write transactions.  If the market price of the
underlying security rises or otherwise is above the exercise price, the put
option will expire worthless and the relevant Fund's gain will be limited to the
premium received.  If the market price of the underlying security declines or
otherwise is below the exercise price, the Fund may elect to close the position
or take delivery of the security at the exercise price and the Fund's return
will be the premium received from the put option minus the amount by which the
market price of the security is below the exercise price.
    
     The Funds may purchase put options to hedge against a decline in the value
of their portfolios.  By using put options in this way, a Fund will reduce any
profit it might otherwise have realized in the underlying security by the amount
of the premium paid for the put option and by transaction costs.  The Funds may
purchase call options to hedge against an increase in the price of securities
that they anticipate purchasing in the future.  The premium paid for the call
option plus any transaction costs will reduce the benefit, if any, realized by a
Fund upon exercise of the option, and, unless the price of the underlying
security rises sufficiently, the option may expire worthless to the Fund.      

     When a Fund purchases an option, the premium paid by it is recorded as an
asset of the Fund.  When the Fund writes an option, an amount equal to the net
premium (the premium less the commission) received by the Fund is included in
the liability section of the Fund's statement of assets and liabilities as a
deferred credit.  The amount of this asset or deferred credit will be
subsequently marked-to-market to reflect the current value of the option
purchased or written.  The current value of the traded option is the last sale
price or, in the absence of a sale, the average of the closing bid and asked
prices.  If an option purchased by the Fund expires unexercised the Fund
realizes a loss equal to the premium paid.  If the Fund enters into a closing
sale transaction on an option purchased by it, the Fund will realize a gain if
the premium received by the Fund on the closing transaction is more than the
premium paid to purchase the option, or a loss if it is less.  If an option
written by the Fund expires on the stipulated expiration date or if the Fund
enters into a closing purchase transaction, it will realize a gain (or loss if
the cost of a closing purchase transaction exceeds the net premium received when
the option is sold) and the deferred credit 

                                       12
<PAGE>
 
related to such option will be eliminated. If an option written by the Fund is
exercised, the proceeds of the sale will be increased by the net premium
originally received and the Fund will realize a gain or loss.
    
     There are several risks associated with transactions in options on
securities and indices.  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.  An option writer unable to effect a closing purchase transaction
will not be able to sell the underlying security (in the case of a covered call
option) or liquidate the earmarked securities (in the case of a secured put
option) until the option expires or the optioned security is delivered upon
exercise with the result that the writer in such circumstances will be subject
to the risk of market decline or appreciation in the security during such
period.     

     There is no assurance that a Fund will be able to close an unlisted option
position.  Furthermore, unlisted options are not subject to the protections
afforded purchasers of listed options by the Options Clearing Corporation, which
performs the obligations of its members who fail to do so in connection with the
purchase or sale of options.
    
     In addition, a liquid secondary market for particular options, whether
traded over-the-counter or on a national securities exchange ("Exchange"), may
be absent for reasons which include the following: there may be insufficient
trading interest in certain options; restrictions may be imposed by an Exchange
on opening transactions or closing transactions or both; trading halts,
suspensions or other restrictions may be imposed with respect to particular
classes or series of options or underlying securities; unusual or unforeseen
circumstances may interrupt normal operations on an Exchange; the facilities of
an Exchange or the Options Clearing Corporation may not at all times be adequate
to handle current trading volume; or one or more Exchanges could, for economic
or other reasons, decide or be compelled at some future date to discontinue the
trading of options (or a particular class or series of options), in which event
the secondary market on that Exchange (or in that class or series of options)
would cease to exist, although outstanding options that had been issued by the
Options Clearing Corporation as a result of trades on that Exchange would
continue to be exercisable in accordance with their terms.

     Currency transactions, including options on currencies and currency
futures, are subject to risks different from those of other portfolio
transactions.  Because currency control is of great importance to the issuing
governments and influences economic planning and policy, purchases and sales of
currency and related instruments can be negatively affected by government
exchange controls, blockages, and manipulations or exchange restrictions imposed
by governments.  These can result in losses to a Fund if it is unable to deliver
or receive currency or funds in settlement of obligations and could also cause
hedges it has entered into to be rendered useless, resulting in full currency
exposure as well as the incurring of transaction costs.  Buyers and sellers of
currency futures are subject to the same risks that apply to the use of futures
generally.  Further, settlement of a currency futures contract for the purchase
of most currencies must occur at a bank based in the issuing nation.  Trading
options on currency futures is relatively new, and the ability to establish and
close out positions on such options is subject to the maintenance of a liquid
market which may not always be available.  Currency exchange rates may fluctuate
based on factors extrinsic to the issuing country's economy. 

     REAL ESTATE SECURITIES.  The Real Estate Fund may invest without limit in
shares of real estate investment trusts ("REITs").  The Equity Funds and the 
Balanced Fund may also invest in REITs. REITs pool investors' funds for
investment primarily in income producing real estate or real estate loans or
interests. A REIT is not taxed on income distributed to shareholders if it
complies with several requirements relating to its organization, ownership,
assets, and income and a requirement that it distribute to its shareholders at
least 95% of it taxable income (other than net capital gains) for each taxable
year. REITs can generally be classified as Equity REITs, Mortgage REITs and
Hybrid REITs. Equity REITs, which invest the majority of their assets directly
in real property, derive their income primarily from rents. Equity REITs can
also realize capital gains by selling properties that have appreciated in value.
Mortgage REITs, which invest the majority of their assets in real estate
mortgages, derive their income primarily from interest payments. Hybrid REITs
combine the characteristics of both Equity REITs and Mortgage REITs. The Funds
will not invest in real estate directly, but only in securities issued by real
estate companies. However, the Funds may be subject to risks similar to those
associated with the direct ownership of real estate (in addition to securities
markets risks) because of its policy of concentration in the securities of
companies in the real estate industry. These include declines in the value of
real estate, risks related to general and local economic conditions, dependency
on     

                                       13
<PAGE>

management skill, heavy cash flow dependency, possible lack of availability of
mortgage funds, overbuilding, extended vacancies of properties, increased
competition, increases in property taxes and operating expenses, changes in
zoning laws, losses due to costs resulting from the clean-up of environmental
problems, liability to third parties for damages resulting from environmental
problems, casualty or condemnation losses, limitations on rents, changes in
neighborhood values, the appeal of properties to tenants and changes in interest
rates.
    
     In addition to these risks, Equity REITs may be affected by changes in the
value of the underlying property owned by the trusts, while Mortgage REITs may
be affected by the quality of any credit extended.  Further, Equity and Mortgage
REITs are dependent upon management skills and generally may not be diversified.
Equity and Mortgage REITs are also subject to heavy cash flow dependency,
defaults by borrowers and self-liquidation.  In addition, Equity and Mortgage
REITs could possibly fail to qualify for the beneficial tax treatment available
to REITs under the Internal Revenue Code of 1986, as amended (the "Internal
Revenue Code"), or to maintain their exemptions from registration under the 1940
Act.  The above factors may also adversely affect a borrower's or a lessee's
ability to meet its obligations to the REIT.  In the event of a default by a
borrower or lessee, the REIT may experience delays in enforcing its rights as a
mortgagee or lessor and may incur substantial costs associated with protecting
investments.

     REPURCHASE AGREEMENTS.  Each of the Funds may agree to purchase securities
from financial institutions such as member banks of the Federal Reserve System,
any foreign bank or any domestic or foreign broker/dealer that is recognized as
a reporting government securities dealer, subject to the seller's agreement to
repurchase the securities at an agreed-upon time and price ("repurchase
agreements").  The Short Term Treasury Fund will only invest in repurchase
agreements fully collateralized by U.S. Treasury securities.  The Advisor (Sub-
Advisor with respect to the Framlington Funds) will review and continuously
monitor the creditworthiness of the seller under a repurchase agreement, and
will require the seller to maintain collateral in an amount that is greater than
the repurchase price.  Default by, or bankruptcy of, the seller would, however,
expose a Fund to possible loss because of adverse market action or delays in
connection with the disposition of underlying obligations except with respect to
repurchase agreements secured by U.S. Government securities.  With respect to
the Money Market Funds, the securities held subject to a repurchase agreement
may have stated maturities exceeding thirteen months, provided the repurchase
agreement itself matures in 397 days or less.      

     The repurchase price under repurchase agreements generally equals the price
paid by a Fund plus interest negotiated on the basis of current short-term rates
(which may be more or less than the rate on the securities underlying the
repurchase agreement).

     Securities subject to repurchase agreements will be held, as applicable, by
the Trust's, Framlington's or the Company's custodian (or sub-custodian) in the
Federal Reserve/Treasury book-entry system or by another authorized securities
depositary.  Repurchase agreements are considered to be loans by a Fund under
the 1940 Act.
    
     REVERSE REPURCHASE AGREEMENTS.  Each Fund (except the Tax-Free Money Market
Fund, Tax-Free Bond Funds and Short Term Treasury Fund) may borrow funds for
temporary or emergency purposes by selling portfolio securities to financial
institutions such as banks and broker/dealers and agreeing to repurchase them at
a mutually specified date and price ("reverse repurchase agreements").  Reverse
repurchase agreements involve the risk that the market value of the securities
sold by a Fund may decline below the repurchase price.  A Fund will pay interest
on amounts obtained pursuant to a reverse repurchase agreement.  While reverse
repurchase agreements are outstanding, a Fund will maintain cash, U.S.
Government securities or other liquid securities designated on the books of the
Fund or the Fund's sub-custodian in an amount at least equal to the market value
of the securities, plus accrued interest, subject to the agreement.      

     RIGHTS AND WARRANTS.  As stated in their Prospectuses, the Equity Funds and
the Balanced Fund may purchase warrants, which are privileges issued by
corporations enabling the owners to subscribe to and purchase a specified number
of shares of the corporation at a specified price during a specified period of
time.  Subscription rights normally have a short life span to expiration.  The
purchase of warrants involves the risk that a Fund could lose the purchase value
of a warrant if the right to subscribe to additional shares is not exercised
prior to the warrant's expiration.  Also, the purchase of warrants involves the
risk that the effective price paid for the warrant 

                                       14
<PAGE>
 
added to the subscription price of the related security may exceed the value of
the subscribed security's market price such as when there is no movement in the
level of the underlying security.

     SHORT SALES.  The Global Financial Services Fund may make short sales of
securities.  A short sale is a transaction in which the Fund sells a security it
does not own in anticipation that the market price of that security will
decline.  When the Fund makes a short sale, it must borrow the security sold
short and deliver it to the broker-dealer through which it made the short sale
as collateral for its obligation to deliver the security upon conclusion of the
sale.  The Fund may also sell securities that it owns or has the right to
acquire at no additional cost but does not intend to deliver to the buyer, a
practice known as selling short "against-the-box."  The Fund may have to pay a
fee to borrow particular securities and is often obligated to pay over any
payments received on such borrowed securities.  The Fund's obligation to replace
the borrowed security will be secured by collateral deposited with the broker-
dealers, usually cash, U.S. Government securities or other highly liquid
securities similar to those borrowed.  The Fund will also be required to deposit
similar collateral with its custodian or sub-custodian to the extent necessary
so that the value of both collateral deposits in the aggregate is at all times
equal to as least 100% of the current market value of the security sold short.
Depending on arrangements made with the broker-dealer from which it borrowed the
security regarding payment over any received by the Fund on such security, the
Fund may not received any payments (including interest) on its collateral
deposited with such broker-dealer. The Fund will incur transaction costs,
including interest expenses, in connection with opening, maintaining, and
closing short sales.

     If the price of the security sold short increases between the time of the
short sale and the time the Fund replaces the borrowed security, the Fund will
incur a loss; conversely, if the price declines, the Fund will realize a capital
gain.  Any gain is limited to the price at which it sold the security short; its
potential loss is theoretically unlimited.
    
     STAND-BY COMMITMENTS.  The Balanced Fund, Cash Investment Fund, Money
Market Fund, the Tax-Free Bond Funds and Tax-Free Money Market Fund may each
enter into stand-by commitments with respect to municipal obligations held by
it.  Under a stand-by commitment, a dealer agrees to purchase at the Fund's
option a specified municipal obligation at its amortized cost value to the Fund
plus accrued interest, if any.  Stand-by commitments may be exercisable by a
Fund at any time before the maturity of the underlying municipal obligations and
may be sold, transferred or assigned only with the instruments involved.      

     The Trust expects that stand-by commitments will generally be available
without the payment of any direct or indirect consideration.  However, if
necessary or advisable, a Fund may pay for a stand-by commitment either
separately in cash or by paying a higher price for municipal obligations which
are acquired subject to the commitment (thus reducing the yield to maturity
otherwise available for the same securities).  The total amount paid in either
manner for outstanding stand-by commitments held by a Fund will not exceed  1/2
of 1% of the value of such Fund's total assets calculated immediately after each
stand-by commitment is acquired.
    
     The Funds intend to enter into stand-by commitments only with dealers,
banks and broker/dealers which, in the Advisor's opinion, present minimal credit
risks.  The Tax-Free Bond Funds and the Tax-Free Money Market Fund will acquire
stand-by commitments solely to facilitate portfolio liquidity and do not intend
to exercise their rights thereunder for trading purposes.  The acquisition of a
stand-by commitment will not affect the valuation of the underlying municipal
obligation.  The actual stand-by commitment will be valued at zero in
determining net asset value.  Accordingly, where a Fund pays directly or
indirectly for a stand-by commitment, its cost will be reflected as an
unrealized loss for the period during which the commitment is held by such Fund
and will be reflected in realized gain or loss when the commitment is exercised
or expires.

     STOCK INDEX FUTURES, OPTIONS ON STOCK AND BOND INDICES AND OPTIONS ON STOCK
AND BOND INDEX FUTURES CONTRACTS.  The Equity Funds, the Balanced Fund, the Bond
Funds and the Tax-Free Bond Funds (other than the Tax-Free Intermediate Bond
Fund) may purchase and sell stock index futures, options on stock and bond
indices and options on stock and bond index futures contracts as a hedge against
movements in the equity and bond markets.  The Tax-Free Intermediate Bond Fund
may purchase and sell bond index futures contracts.  The      

                                       15
<PAGE>

     
International Bond Fund may purchase and sell options on bond index futures
contracts as a hedge against movements in the bond markets.      

     A stock index futures contract is an agreement in which one party agrees to
deliver to the other an amount of cash equal to a specific dollar amount times
the difference between the value of a specific stock index at the close of the
last trading day of the contract and the price at which the agreement is made.
No physical delivery of securities is made.

     Options on stock and bond indices are similar to options on specific
securities, described above, except that, rather than the right to take or make
delivery of the specific security at a specific price, an option on a stock or
bond index gives the holder the right to receive, upon exercise of the option,
an amount of cash if the closing level of that stock or bond index is greater
than, in the case of a call option, or less than, in the case of a put option,
the exercise price of the option.  This amount of cash is equal to such
difference between the closing price of the index and the exercise price of the
option expressed in dollars times a specified multiple.  The writer of the
option is obligated, in return for the premium received, to make delivery of
this amount.  Unlike options on specific securities, all settlements of options
on stock or bond indices are in cash, and gain or loss depends on general
movements in the stocks included in the index rather than price movements in
particular stocks.

     If the Advisor (Sub-Advisor with respect to the Framlington Funds) expects
general stock or bond market prices to rise, it might purchase a stock index
futures contract, or a call option on that index, as a hedge against an increase
in prices of particular securities it ultimately wants to buy.  If in fact the
index does rise, the price of the particular securities intended to be purchased
may also increase, but that increase would be offset in part by the increase in
the value of the futures contract or index option resulting from the increase in
the index.  If, on the other hand, the Advisor or Sub-Advisor, as the case may
be, expects general stock or bond market prices to decline, it might sell a
futures contract, or purchase a put option, on the index.  If that index does in
fact decline, the value of some or all of the securities in the Funds' portfolio
may also be expected to decline, but that decrease would be offset in part by
the increase in the value of the Fund's position in such futures contract or put
option.

     The Equity Funds, the Balanced Fund, the Bond Funds and the Tax-Free Bond
Funds (other than Tax-Free Intermediate Bond Fund) may purchase and write call
and put options on stock index futures contracts and each such Fund and the
International Bond Fund may purchase and write call and put options on bond
index futures contracts.  Each such Fund may use such options on futures
contracts in connection with its hedging strategies in lieu of purchasing and
selling the underlying futures or purchasing and writing options directly on the
underlying securities or indices.  For example, such Funds may purchase put
options or write call options on stock and bond index futures (only bond index
futures in the case of the International Bond Fund), rather than selling futures
contracts, in anticipation of a decline in general stock or bond market prices
or purchase call options or write put options on stock or bond index futures,
rather than purchasing such futures, to hedge against possible increases in the
price of securities which such Funds intend to purchase.
    
     In connection with transactions in stock or bond index futures, stock or
bond index options and options on stock or bond index futures, the Funds will be
required to deposit as "initial margin" an amount of cash or short-term U.S.
Government securities equal to between 5% to 8% of the contract amount.
Thereafter, subsequent payments (referred to as "variation margin") are made to
and from the broker to reflect changes in the value of the option or futures
contract.  No Fund may at any time commit more than 5% of its total assets to
initial margin deposits on futures contracts, index options and options on
futures contracts.      

     STRIPPED SECURITIES.  Certain Funds may acquire U.S. Government obligations
and their unmatured interest coupons that have been separated ("stripped") by
their holder, typically a custodian bank or investment brokerage firm.  Having
separated the interest coupons from the underlying principal of the U.S.
Government obligations, the holder will resell the stripped securities in
custodial receipt programs with a number of different names, including "Treasury
Income Growth Receipts" ("TIGRs") and "Certificate of Accrual on Treasury
Securities" ("CATS").  The stripped coupons are sold separately from the
underlying principal, which is usually sold at a deep discount because the buyer
receives only the right to receive a future fixed payment on the security and
does not receive any rights to periodic interest (cash) payments.  The
underlying U.S. Treasury bonds and notes 

                                       16
<PAGE>
 
themselves are held in book-entry form at the Federal Reserve Bank or, in the
case of bearer securities (i.e., unregistered securities which are ostensibly
owned by the bearer or holder), in trust on behalf of the owners. Counsel to the
underwriters of these certificates or other evidences of ownership of U.S.
Treasury securities have stated that, in their opinion, purchasers of the
stripped securities most likely will be deemed the beneficial holders of the
underlying U.S. Government obligations for federal tax and securities purposes.
The Company, the Trust and Framlington are not aware of any binding legislative,
judicial or administrative authority on this issue.

     Only instruments which are stripped by the issuing agency will be
considered U.S. Government obligations.  Securities such as CATS and TIGRs which
are stripped by their holder do not qualify as U.S. Government obligations.
    
     Within the past several years the U.S. Treasury Department has facilitated
transfers of ownership of zero coupon securities by accounting separately for
the beneficial ownership of particular interest coupon and principal payments on
U.S. Treasury securities through the Federal Reserve book-entry record-keeping
system.  The Federal Reserve program as established by the U.S. Treasury
Department is known as "STRIPS" or "Separate Trading of Registered Interest and
Principal of Securities." Under the STRIPS program, a Fund is able to have its
beneficial ownership of zero coupon securities recorded directly in the book-
entry record-keeping system in lieu of having to hold certificates or other
evidences of ownership of the underlying U.S. Treasury securities.      

     In addition, the Bond Fund, Intermediate Bond Fund, International Bond Fund
and U.S. Government Income Fund may invest in stripped mortgage-backed
securities ("SMBS"), which represent beneficial ownership interests in the
principal distributions and/or the interest distributions on mortgage assets.
SMBS are usually structured with two classes that receive different proportions
of the interest and principal distributions on a pool of mortgage assets.  One
type of SMBS 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 common case, one
class of SMBS will receive all of the interest (the interest-only or "IO"
class), while the other class will receive all of the principal (the principal-
only or "PO" class).  SMBS may be issued by FNMA or FHLMC.

     The original principal amount, if any, of each SMBS class represents the
amount payable to the holder thereof over the life of such SMBS class from
principal distributions of the underlying mortgage assets, which will be zero in
the case of an IO class.  Interest distributions allocable to a class of SMBS,
if any, consist of interest at a specified rate on its principal amount, if any,
or its notional principal amount in the case of an IO class.  The notional
principal amount is used solely for purposes of the determination of interest
distributions and certain other rights of holders of such IO class and does not
represent an interest in principal distributions of the mortgage assets.

     Yields on SMBS will be extremely sensitive to the prepayment experience on
the underlying mortgage loans, and there are other associated risks.  For IO
classes of SMBS and SMBS that were purchased at prices exceeding their principal
amounts there is a risk that a Fund may not fully recover its initial
investment.

     The determination of whether a particular government-issued IO or PO backed
by fixed-rate mortgages is liquid may be made under guidelines and standards
established by the Boards of Directors/Trustees.  Such securities may be deemed
liquid if they can be disposed of promptly in the ordinary course of business at
a value reasonably close to that used in the calculation of a Fund's net asset
value per share.

     SUPRANATIONAL BANK OBLIGATIONS.  Supranational banks are international
banking institutions designed or supported by national governments to promote
economic reconstruction, development or trade between nations (e.g., The World
Bank).  Obligations of supranational banks may be supported by appropriated but
unpaid commitments of their member countries and there is no assurance these
commitments will be undertaken or met in the future.

     U.S. GOVERNMENT OBLIGATIONS.  The Funds may purchase obligations issued or
guaranteed by the U.S. Government and, except in the case of the U.S. Treasury
Money Market Fund, U.S. Government agencies and instrumentalities.  Obligations
of certain agencies and instrumentalities of the U.S. Government, such as those
of     

                                       17
<PAGE>

     
GNMA, are supported by the full faith and credit of the U.S. Treasury. Others,
such as those of the Export-Import Bank of the United States, are supported by
the right of the issuer to borrow from the U.S. Treasury; and still others, such
as those of the Student Loan Marketing Association, are supported only by the
credit of the agency or instrumentality issuing the obligation. No assurance can
be given that the U.S. Government would provide financial support to U.S.
government-sponsored instrumentalities if it is not obligated to do so by law.
Examples of the types of U.S. Government obligations that may be acquired by the
Funds include U.S. Treasury Bills, U.S. Treasury Notes and U.S. Treasury Bonds
and the obligations of Federal Home Loan Banks, Federal Farm Credit Banks,
Federal Land Banks, the Federal Housing Administration, Farmers Home
Administration, Export-Import Bank of the United States, Small Business
Administration, FNMA, GNMA, General Services Administration, Student Loan
Marketing Association, Central Bank for Cooperatives, FHLMC, Federal
Intermediate Credit Banks and Maritime Administration.      

     VARIABLE AND FLOATING RATE INSTRUMENTS.  Debt instruments may be structured
to have variable or floating interest rates.  Variable and floating rate
obligations purchased by a Fund may have stated maturities in excess of a Fund's
maturity limitation if the Fund can demand payment of the principal of the
instrument at least once during such period on not more than thirty days' notice
(this demand feature is not required if the instrument is guaranteed by the U.S.
Government or an agency thereof).  These instruments may include variable amount
master demand notes that permit the indebtedness to vary in addition to
providing for periodic adjustments in the interest rates.  The Advisor or Sub-
Advisor, as the case may be, will consider the earning power, cash flows and
other liquidity ratios of the issuers and guarantors of such instruments and, if
the instrument is subject to a demand feature, will continuously monitor their
financial ability to meet payment on demand.  Where necessary to ensure that a
variable or floating rate instrument is equivalent to the quality standards
applicable to a Fund, the issuer's obligation to pay the principal of the
instrument will be backed by an unconditional bank letter or line of credit,
guarantee or commitment to lend.  The Money Market Funds will invest in variable
and floating rate instruments only when the Advisor deems the investment to
involve minimal credit risk.

     In determining average weighted portfolio maturity of the Funds, an
instrument will usually be deemed to have a maturity equal to the longer of the
period remaining until the next interest rate adjustment or the time the Fund
involved can recover payment of principal as specified in the instrument.
Variable rate U.S. Government obligations held by the Funds, however, will be
deemed to have maturities equal to the period remaining until the next interest
rate adjustment.

     The absence of an active secondary market for certain variable and floating
rate notes could make it difficult to dispose of the instruments, and a Fund
could suffer a loss if the issuer defaulted or during periods that a Fund is not
entitled to exercise its demand rights.

     Variable and floating rate instruments held by a Fund will be subject to
the Fund's limitation on illiquid investments when the Fund may not demand
payment of the principal amount within seven days absent a reliable trading
market.
    
     GUARANTEED INVESTMENT CONTRACTS.  The Bond Funds, International Bond Fund,
Cash Investment Fund and Money Market Fund may make limited investments in
guaranteed investment contracts ("GICs") issued by U.S. insurance companies.
Pursuant to such contracts, a Fund makes cash contributions to a deposit fund of
the insurance company's general account.  The insurance company then credits to
the Fund on a monthly basis interest which is based on an index (in most cases
this index is expected to be the Salomon Brothers CD Index), but is guaranteed
not to be less than a certain minimum rate.  A GIC is normally a general
obligation of the issuing insurance company and not funded by a separate
account.  The purchase price paid for a GIC becomes part of the general assets
of the insurance company, and the contract is paid from the company's general
assets.  A Fund will only purchase GICs from insurance companies which, at the
time of purchase, have assets of $1 billion or more and meet quality and credit
standards established by the Advisor pursuant to guidelines approved by the
Board of Directors/Trustees.  Generally, GICs are not assignable or transferable
without the permission of the issuing insurance companies, and an active
secondary market in GICs does not currently exist.  Therefore, GICs will
normally be considered illiquid investments, and will be acquired subject to the
Fund's limitation on illiquid investments.      

                                       18
<PAGE>
 
     WHEN-ISSUED PURCHASES AND FORWARD COMMITMENTS (DELAYED-DELIVERY
TRANSACTIONS).  When-issued purchases and forward commitments (delayed-delivery
transactions) are commitments by a Fund to purchase or sell particular
securities with payment and delivery to occur at a future date (perhaps one or
two months later).  These transactions permit the Fund to lock-in a price or
yield on a security, regardless of future changes in interest rates.

     When a Fund agrees to purchase securities on a when-issued or forward
commitment basis, the Fund will earmark cash or liquid portfolio securities
equal to the amount of the commitment.  Normally, the Fund will earmark
portfolio securities to satisfy a purchase commitment, and in such a case the
Fund may be required subsequently to earmark additional assets in order to
ensure that the value of the account remains equal to the amount of the Fund's
commitments.  It may be expected that the market value of the Fund's net assets
will fluctuate to a greater degree when it earmarks portfolio securities to
cover such purchase commitments than when it earmarks cash.  Because a Fund's
liquidity and ability to manage its portfolio might be affected when it earmarks
cash or portfolio securities to cover such purchase commitments, the Advisor
(Sub-Advisor with respect to the Framlington Funds) expects that its commitments
to purchase when-issued securities and forward commitments will not exceed 25%
of the value of a Fund's total assets absent unusual market conditions.

     A Fund will purchase securities on a when-issued or forward commitment
basis only with the intention of completing the transaction and actually
purchasing the securities.  If deemed advisable as a matter of investment
strategy, however, a Fund may dispose of or renegotiate a commitment after it is
entered into, and may sell securities it has committed to purchase before those
securities are delivered to the Fund on the settlement date.  In these cases the
Fund may realize a taxable capital gain or loss.

     When a Fund engages in when-issued and forward commitment transactions, it
relies on the other party to consummate the trade.  Failure of such party to do
so may result in the Fund's incurring a loss or missing an opportunity to obtain
a price considered to be advantageous.

     The market value of the securities underlying a when-issued purchase or a
forward commitment to purchase securities, and any subsequent fluctuations in
their market value, are taken into account when determining the market value of
a Fund starting on the day the Fund agrees to purchase the securities.  The Fund
does not earn interest on the securities it has committed to purchase until they
are paid for and delivered on the settlement date.
    
     YIELDS AND RATINGS.  The yields on certain obligations, including the money
market instruments in which each Fund may invest (such as commercial paper and
bank obligations), are dependent on a variety of factors, including general
money market conditions, conditions in the particular market for the obligation,
the financial condition of the issuer, the size of the offering, the maturity of
the obligation and the ratings of the issue.  The ratings of S&P, Moody's, Duff
& Phelps Credit Rating Co., Thomson Bank Watch, Inc., and other NRSROs represent
their respective opinions as to the quality of the obligations they undertake to
rate.  Ratings, however, are general and are not absolute standards of quality.
Consequently, obligations with the same rating, maturity and interest rate may
have different market prices.

     With respect to each of the Money Market Funds, securities (other than U.S.
Government securities) must be rated (generally, by at least two NRSROs) within
the two highest rating categories assigned to short-term debt securities.  In
addition, each of Cash Investment Fund and Money Market Fund will not invest
more than 5% of its total assets in securities rated in the second highest
rating category by such NRSROs and will not invest more than 1% of its total
assets in such securities of any one issuer.  Each of Cash Investment Fund,
Money Market Fund and Tax-Free Money Market Fund intends to limit investments in
the securities of any single issuer (other than securities issued or guaranteed
by the U.S. Government, its agencies or instrumentalities) to not more than 5%
of the Fund's total assets at the time of purchase, provided that the Fund may
invest up to 25% of its total assets in the securities of any one issuer rated
in the highest rating category by an NRSRO for a period of up to three business
days.  Unrated and certain single rated securities (other than U.S. Government
securities) may be purchased by the Money Market Funds, but are subject to a
determination by the Advisor, in accordance with procedures established by the
Board of Directors/Trustees, that the unrated and single rated securities are of
comparable quality to the appropriate rated securities.

     OTHER.  Subsequent to its purchase by a Fund, a rated security may cease to
be rated or its rating may be reduced below the minimum rating required for
purchase by the Fund.  The Board of Directors/Trustees or the Advisor (Sub-
Advisor with respect to the Framlington Funds), pursuant to guidelines
established by the Boards, will consider such an event in determining whether
the Fund involved should continue to hold the security in accordance with the
interests of the Fund and applicable regulations of the SEC.      

           RISK FACTORS AND SPECIAL CONSIDERATIONS -- INDEX 500 FUND

     Traditional methods of fund investment management typically involve
relatively frequent changes in a portfolio of securities on the basis of
economic, financial and market analysis.  Index funds such as the Index 500 Fund
are not managed in this manner.  Instead, with the aid of a computer program,
the Advisor purchases and sells securities for the Fund in an attempt to produce
investment results that substantially duplicate the performance of the common
stocks included in the S&P 500 Composite Stock Price Index ("S&P 500"), taking
into account redemptions, sales of additional Fund shares, and other adjustments
as described below.

     The Fund does not expect to hold at any particular time all of the stocks
included in the S&P 500.  The Advisor believes, however, that through the
application of capitalization weighing and sector balancing techniques it will
be able to construct and maintain the Fund's investment portfolio so that it
reasonably tracks the performance of the S&P 500.  The Advisor will compare the
industry sector diversification of the stocks the Fund would acquire solely on
the basis of their weighted capitalizations with the industry sector
diversification of all issuers included in the S&P 500.  This comparison is made
because the Advisor believes that, unless the Fund holds all stocks included in
the S&P 500, the selection of stocks for purchase by the Fund solely on the
basis of their weighted market capitalizations would tend to place heavier
concentration in certain industry sectors that are dominated by the larger
corporations, such as communications, automobile, oil and energy.  As a result,
events disproportionately affecting such industries could affect the performance
of the Fund differently than the performance of the S&P 500.  Conversely, if
smaller companies were not purchased by the Fund, the representation of
industries included in the S&P 500 that are not dominated by the most heavily
market-capitalized companies would be reduced or eliminated.

     For these reasons, the Advisor will identify the sectors which are (or,
except for sector balancing, would be) most underrepresented in the Fund's
portfolio and will purchase balancing securities in these sectors until the
portfolio's sector weightings closely match those of the S&P 500.  This process
continues until the portfolio is fully invested (except for cash holdings).

     Redemptions of a substantial number of shares of the Fund could reduce the
number of issuers represented in the Fund's investment portfolio, which could,
in turn, adversely affect the accuracy with which the Fund tracks the
performance of the S&P 500.

     If an issuer drops in ranking, or is eliminated entirely from the S&P 500,
the Advisor may be required to sell some or all of the common stock of such
issuer then held by the Fund.  Sales of portfolio securities may be made at
times when, if the Advisor were not required to effect purchases and sales of
portfolio securities in accordance with the S&P 500, such securities might not
be sold.  Such sales may result in lower prices for such securities than may
have been realized or in losses that may not have been incurred if the Advisor
were not required to effect the purchases and sales.  The failure of an issuer
to declare or pay dividends, the institution against an issuer of potentially
materially adverse legal proceedings, the existence or threat of defaults
materially and adversely affecting an issuer's future declaration and payment of
dividends, or the existence of other materially adverse credit factors will not
necessarily be the basis for the disposition of portfolio securities, unless
such event causes the issuer to be eliminated entirely from the S&P 500.
However, although the Advisor does not intend to screen securities for
investment by the Fund by traditional methods of financial and market analysis,
the Advisor will monitor the Fund's investment with a view towards removing
stocks of companies which exhibit extreme financial distress or which may impair
for any reason the Fund's ability to achieve its investment objective.

     The Fund will invest primarily in the common stocks that constitute the S&P
500 in accordance with their relative capitalization and sector weightings as
described above.  It is possible, however, that the Fund will from 

                                       20
<PAGE>
 
time to time receive, as part of a "spin-off" or other corporate reorganization
of an issuer included in the S&P 500, securities that are themselves outside the
S&P 500. Such securities will be disposed of by the Fund in due course
consistent with the Fund's investment objective.

     In addition, the Index 500 Fund may invest in Standard & Poor's Depository
Receipts ("SPDRs").  SPDRs are securities that represent ownership in the SPDR
Trust, a long-term unit investment trust which is intended to provide investment
results that generally correspond to the price and yield performance of the S&P
500.  SPDR holders are paid a "Dividend Equivalent Amount" that corresponds to
the amount of cash dividends accruing to the securities in the SPDR Trust, net
of certain fees and expenses charged to the Trust.  Because of these fees and
expenses, the dividend yield for SPDRs may be less than that of the S&P 500.
SPDRs are traded on the American Stock Exchange.

     The Fund may also purchase put and call options on the S&P 500 and S&P 100
stock indices, which are traded on national securities exchanges.  In addition,
the Fund may enter into transactions involving futures contracts (and futures
options) on these two stock indices and may purchase securities of other
investment companies that are structured to seek a similar correlation to the
S&P 500.  These transactions are effected in an effort to have fuller exposure
to price movements in the S&P 500 pending investment of purchase orders or while
maintaining liquidity to meet potential shareholder redemptions.  Transactions
in option and stock index futures contracts may be desirable to hedge against a
price movement in the S&P 500 at times when the Fund is not fully invested in
stocks that are included in the S&P 500.  For example, by purchasing a futures
contract, the Fund may be able to reduce the potential that cash inflows will
disrupt its ability to track the S&P 500, since the futures contracts may serve
as a temporary substitute for stocks which may then be purchased in an orderly
fashion.  Similarly, because futures contracts only require a small initial
margin deposit, the Fund may be able, as an effective matter, to be fully
invested in the S&P 500 while keeping a cash reserve to meet potential
redemptions.  See Appendix B to this Statement of Additional Information.

       RISK FACTORS AND SPECIAL CONSIDERATIONS -- MICHIGAN BOND FUND AND
                        TAX-FREE INTERMEDIATE BOND FUND
                                        
     The information set forth below is derived in substantial part from the
official statements prepared in connection with the issuance of Michigan
municipal bonds and similar obligations and other sources that are generally
available to investors.  The information is provided as general information
intended to give a recent historical description and is not intended to indicate
future or continuing trends in the financial or other positions of the State of
Michigan (the "State").  The Company has not independently verified this
information.

     The State's Constitution limits the amount of total State revenues raised
from taxes and other sources.  State revenues (excluding federal aid and
revenues for payment of principal and interest on general obligation bonds) in
any fiscal year are limited to a specified percentage of State personal income
in the prior calendar year or average of the prior three calendar years,
whichever is greater.  The percentage is based upon the ratio of the 1978-79
fiscal year revenues to total 1977 State personal income.  If any fiscal year
revenues exceed the revenue limitation by 1%, the entire amount exceeding the
limitation must be rebated in the following fiscal year's personal income tax or
single business tax.  Annual excesses of less than 1% may be transferred into
the State's Budget Stabilization Fund.  The State may raise taxes in excess of
the limit in emergency situations.

     The State Constitution limits the purposes for which State general
obligation debt may be issued.  Such debt is limited to short-term debt for
State operating purposes, short and long-term debt for the purpose of making
loans to school districts and long-term debt for voter approved purposes.  The
State's Constitution also directs or restricts the use of certain revenues.

     The State finances its operations through the State's General Fund and
special revenue funds.  The General Fund receives revenues of the State that are
not specifically required to be included in the special revenue funds.  General
Fund revenues are obtained approximately 55% from the payment of State taxes and
45% from federal and non-tax revenue sources.  Tax revenues credited to the
General Fund include the personal income tax, the single business tax and
approximately 15% of the sales tax collections.

                                       21
<PAGE>
 
     Expenditures are not permitted by the State Constitution to exceed
available revenues.  The State Constitution requires that the Governor, with the
approval of the appropriating committees of the State House and Senate, reduce
expenditures whenever it appears that the actual revenues will be less than the
originally projected revenues upon which the budget was based.

     In 1994, a ballot proposal ("Proposal A") to implement extensive property
tax and school finance reform measures was subject to voter approval and in fact
approved on March 15, 1994.  Under Proposal A as approved, effective May 1,
1994, the State sales and use tax increased from 4% to 6%, the State income tax
decreased from 4.6% to 4.4%, the cigarette tax increased from $.25 to $.75 per
pack, and an additional tax of 16% of the wholesale price is imposed on certain
other tobacco products.  As of January 1, 1995, a 0.75% real estate transfer tax
also became effective.  In 1994, a State education property tax of 6 mills was
imposed on all real property and personal property currently subject to the
general property tax.  In addition, all school boards can now, with voter
approval, levy up to the lesser of 18 mills or the number of mills levied in
1993 for school operating purposes, on non-homestead property.  Proposal A
contained additional provisions regarding the ability of local school districts
to levy taxes as well as a limit on assessment increases for each parcel of
property, beginning in 1995 to the lesser of 5% or the rate of inflation.  When
property is subsequently sold, its assessed value is adjusted equal to 50% of
true cash value.  Under Proposal A, much of the additional revenue generated by
these taxes is dedicated to the State School Aid Fund.

     Proposal A shifts significant portions of the cost of local school
operations from local school districts to the State and raises additional State
revenues to fund these additional State expenses.  These additional revenues
will be included within the State's constitutional revenue limitations and may
impact the State's ability to raise additional revenues in the future.

     The State is a party to various legal proceedings seeking damages or
injunctive or other relief.  In addition to routine litigation, certain of these
proceedings could, if unfavorably resolved from the point of view of the State,
substantially affect State programs or finances.  These lawsuits involve
programs generally in the areas of corrections, highway maintenance, social
services, tax collection, commerce and budgetary reductions to school districts
and governmental units and court funding. Although no opinion is expressed with
respect to the ultimate disposition and consequences of any litigation in
combination with any State Revenue loss, the implementation of any tax reduction
proposal or the failure of the State to realize any budget assumption, the
Attorney General of the State has indicated in a recent official statement
prepared in connection with issuance of general obligation bonds of the State
that, except as listed below, such ultimate dispositions and consequences of any
single proceeding or all legal proceedings should not themselves have a material
adverse effect on the security for such bonds.

     On August 22, 1994, the Ingham Circuit and probate courts, together with
the 55th District Court, filed suits in the Court of Claims and Ingham County
Circuit Court against the State of Michigan and Ingham County for declaratory
and injunctive relief, and for damages, due to the alleged failure of the State
Court Administrative Office to properly calculate Ingham County's reimbursement
under the court funding statute. These cases have been dismissed by stipulation
of the parties because the plaintiffs are raising the same claims as members of
a class action captioned as 10th Judicial Circuit, et al v State of Michigan, et
al. Plaintiffs assert that the amount in controversy exceeds $5 million dollars.
The case is currently pending final class certification.

     In an order dated June 10, 1997 and a decision rendered July 31, 1997, the
Michigan Supreme Court decided, in the consolidated cases of Durant v State of
Michigan and Schmidt v State of Michigan, that the special education, special
education transportation, bilingual education, driver training and school lunch
programs provided by local school districts are state mandated programs within
the meaning of Michigan Constitution, Article 9, (S) 29 (part of the so-called
Headlee Amendment) and, therefore, the state is obligated to fund these programs
at levels established by the Headlee Amendment.  In fashioning a remedy in this
case of first impression under the Headlee Amendment, the Court concluded that,
in future cases, the correct remedy will typically be limited to a declaratory
judgment.  However, due to the protracted nature of the Durant and Schmidt
litigation, the Court ruled that money damages, without interest, shall be paid
to the 84 plaintiff school districts for the full amount of the underfunding for
the state mandated programs during the 1991-92, 1992-93, and 1993-94 school
years.  On November 19, 1997, the Governor signed legislation providing
approximately $212 million to the 84 plaintiff school districts to cover the
underfunding for those three years.  That payment was made to the 84 plaintiff
school districts on April 15, 1998 from the State's Budget Stabilization Fund.
The board of education of each plaintiff school district is to determine the
appropriate distribution of the award between taxpayer relief and/or use by the
district for other public purposes.  The Court has affirmed the award to
plaintiffs of their costs including attorney fees.  Approximately 400 other
school districts have asserted similar claims.  In companion legislation signed
by the Governor on November 19, 1997, the State will pay each "non-Durant"
school district for its underfunded state mandated program costs for those same
three years, if the district agreed, by March 2, 1998, to waive any claim
against the State of the same nature as the claims made by the 84 Durant
plaintiffs through September 30, 1997.  All "non-Durant" school districts
submitted the statutory waiver by March 2, 1998.  It is estimated that the
aggregate payments to the "non-Durant" school districts will, over time, total
$632 million.  Those payments, commencing in fiscal year 1998-1999, will be paid
out of the Budget Stabilization Fund and the General Fund, half in annual
payments over 10 years and half in annual payments over 15 years.

     On May 14, 1998, more than 100 Michigan school districts and individuals
filed suit in the Michigan Court of Appeals, asserting that the current version
of the state school aid act violates the Headlee Amendment, in much the same
manner as prior versions of the act were ruled unconstitutional by the Michigan
Supreme Court in Durant v State Board of Education, 456 Mich 175 (1977). Durant,
et al. v State, et al. ("Durant II"). The Durant II plaintiffs are claiming
damages of approximately $347 million for the 1997-1998 school year for the
State's alleged underfunding of special education services, special education
transportation, and school lunch programs. The Durant II plaintiffs are also
requesting a declaratory judgment that the current version of the state school
aid act will not provide proper funding levels for future school years. They
also seek attorney fees and costs of the litigation.

     The principal sectors of Michigan's diversified economy are the
manufacturing of durable goods (including automobiles and components and office
equipment), tourism and agriculture. The health of the State's economy, and in
particular its durable goods manufacturing industries, is susceptible to a long-
term increase in the cost of energy and energy related products. As reflected in
historical employment figures, the State's economy has lessened its dependence
upon durable goods manufacturing. In 1960, employment in such industry accounted
for 33% of the State's work force. By 1997, this figure had fallen to 14.5%.
Although manufacturing (including auto-related manufacturing) continues to be an
important part of the State's economy, approximately 66% of the civilian labor
force is currently engaged in service related employment.

     On October 1, 1997, the State created the Year 2000 Project Office to
provide guidance, coordinate oversight for application software, manage Year
2000 funds, provide monitoring support, quality assurance and other matters. The
State has undertaken an inventory and assessment of all applications and
classified the software, has appropriated funds to carry out the project and
informed State agencies of the need to develop contingent plans for mission-
critical systems. The State's goal is to have all critical applications operable
by December 31, 1998, and all other applications operable by September 30, 1999.

     Although the State is currently on schedule to meet its objectives for Year
2000 compliance, the State has not yet achieved Year 2000 compliance. Although
the State has expressed its belief that it will continue to meet the objectives
and time frames set forth above for the Year 2000 Project, there can be no
assurance that such completion will be done in a timely manner or that any other
organization or governmental agency with which the State electronically
interacts, including State vendors and the federal government, will be Year 2000
compliant. In the event of any such occurrences, the State may face material
adverse consequences with respect to its revenues and operations.

     As of the date of this Statement of Additional Information, the State's
general obligation bonds have been rated "AA+" by Standard & Poor's Ratings
Service, a division of The McGraw-Hill Companies, Inc. ("S&P"), "Aa1" by Moody's
Investors Service, Inc. ("Moody's"), and "AA+" by Fitch ICBA ("Fitch"). In
January, 1998, the State received an upgrade from S&P from its prior rating of
"AA". In March, 1998, the State received an upgrade from Moody's from its prior
rating of "Aa2". In April, 1998, the State received an upgrade from Fitch from
its prior rating of "AA". Such ratings are in each case based upon certain
information and materials concerning the Bonds and the State furnished by the
State to such rating agencies. Any explanation of the significance of such
ratings may be obtained only from the rating agencies furnishing the same. There
is no assurance that such ratings will prevail for any given period of time or
that they will not be revised downward or withdrawn entirely by any or all of
such rating agencies if, in the judgment of any or all of them, circumstances so
warrant. Any such downward revision or withdrawal of such ratings, or any or all
of them, may have an adverse effect on the market price of the Bonds. To the
extent that the portfolio of Michigan municipal bonds is comprised of revenue of
general obligations of local governments or authorities, rather than general
obligations of the State of Michigan itself, ratings on such Michigan
obligations will be different from those given to the State of Michigan and
their value may be independently affected by economic matters not directly
impacting the State.
     

                             INVESTMENT LIMITATIONS
                                        
     Each Fund is subject to the investment limitations enumerated in this
section which may be changed with respect to a particular Fund only by a vote of
the holders of a majority of such Fund's outstanding shares (as defined under
"Miscellaneous Shareholder Approvals").

                                       22

     No Fund of the Trust may:

     1.   Purchase securities of any one issuer (other than securities issued or
          guaranteed by the U.S. Government, its agencies or instrumentalities
          or certificates of deposit for any such securities) if more than 5% of
          the value of the Fund's total assets (taken at current value) would be
          invested in the securities of such issuer, or more than 10% of the
          issuer's outstanding voting securities would be owned by the Fund or
          the Trust, except that (a) with respect to each Fund, other than the
          Michigan Bond Fund and the Tax-Free Intermediate Bond Fund, up to 25%
          of the value of the Fund's total assets (taken at current value) may
          be invested without regard to these limitations and (b) with respect
          to the Michigan Bond Fund and the Tax-Free Intermediate Bond Fund, up
          to 50% of the value of the Fund's total assets may be invested without
          regard to these limitations so long as no more than 25% of the value
          of the Fund's total assets are invested in the securities of any one
          issuer.  For purposes of this limitation, a security is considered to
          be issued by the entity (or entities) whose assets and revenues back
          the security.  A guarantee of a security is not deemed to be a
          security issued by the guarantor when the value of all securities
          issued and guaranteed by the guarantor, and owned by the Fund, does
          not exceed 10% of the value of the Fund's total assets;
    
     2.   Borrow money or issue senior securities except that each Fund may
          borrow from banks and enter into reverse repurchase agreements for
          temporary purposes in amounts up to one-third of the value of its
          total assets at the time of such borrowing; or mortgage, pledge or
          hypothecate any assets, except in connection with any such borrowing
          and then in amounts not in excess of one-third of the value of the
          Fund's total assets at the time of such borrowing.  No Fund will
          purchase securities while its aggregate borrowings (including reverse
          repurchase agreements and borrowing from banks) in excess of 5% of its
          total assets are outstanding.  Securities held in escrow or separate
          accounts in connection with a Fund's investment practices are not
          deemed to be pledged for purposes of this limitation;     

     3.   Purchase any securities which would cause 25% or more of the value of
          the Fund's total assets at the time of purchase to be invested in the
          securities of one or more issuers conducting their principal business
          activities in the same industry, provided that (a) there is no
          limitation with respect to (i) instruments that are issued (as defined
          in investment limitation 1 above) or guaranteed by the United States,
          any state, territory or possession of the United States, the District
          of Columbia or any of their authorities, agencies, instrumentalities
          or political subdivisions, (ii) with respect to the Money Market Funds
          only, instruments issued by domestic branches of U.S. banks and (iii)
          repurchase agreements secured by the instruments described in clauses
          (i) and, with respect to the Money Market Funds, (ii); (b) wholly-
          owned finance companies will be considered to be in the industries of
          their parents if their activities are primarily related to financing
          the activities of the parents; and (c) utilities will be divided
          according to their services, for example, gas, gas transmission,
          electric and gas, electric and telephone will each be considered a
          separate industry;

     4.   Purchase or sell real estate, except that each Fund may purchase
          securities of issuers which deal in real estate and may purchase
          securities which are secured by interests in real estate;

     5.   Acquire any other investment company or investment company security
          except in connection with a merger, consolidation, reorganization or
          acquisition of assets or where otherwise permitted by the 1940 Act;

     6.   Act as an underwriter of securities within the meaning of the
          Securities Act of 1933, as amended, except to the extent that the
          purchase of obligations directly from the issuer thereof, or the
          disposition of securities, in accordance with the Fund's investment
          objective, policies and limitations may be deemed to be underwriting;

                                      23
<PAGE>
 
     7.   Write or sell put options, call options, straddles, spreads, or any
          combination thereof except for transactions in options on securities,
          securities indices, futures contracts, options on futures contracts
          and transactions in securities on a when-issued or forward commitment
          basis, and except that each Equity and Bond Fund may enter into
          forward currency contracts in accordance with its investment
          objectives and policies.  Notwithstanding the above, the Tax-Free
          Intermediate Bond Fund may not write or purchase options, including
          puts, calls, straddles, spreads, or any combination thereof;

     8.   Purchase securities of companies for the purpose of exercising
          control;

     9.   Purchase securities on margin, make short sales of securities or
          maintain a short position, except that (a) this investment limitation
          shall not apply to a Fund's transactions in futures contracts and
          related options, a Fund's sale of securities short against the box or
          a Fund's transactions in securities on a when-issued or forward
          commitment basis, and (b) a Fund may obtain short-term credit as may
          be necessary for the clearance of purchases and sales of portfolio
          securities;
    
     10.  Purchase or sell commodity contracts, or invest in oil, gas or mineral
          exploration or development programs, except that each Fund may, to the
          extent appropriate to its investment policies, purchase publicly
          traded securities of companies engaging in whole or in part in such
          activities, may enter into futures contracts and related options, and
          may engage in transactions in securities on a when-issued or forward
          commitment basis, and except that each Equity Fund and Bond Fund may
          enter into forward currency contracts in accordance with its
          investment objectives and policies; or    

     11.  Make loans, except that each Fund may purchase and hold debt
          instruments (whether such instruments are part of a public offering or

     8.   Purchase securities on margin, or make short sales of securities

          Intranet related businesses; and (iv) provided that with respect to
          the Equity Selection Fund utilities will be divided according to their
          services, for example, gas, gas transmission, electric and gas,
          electric and telephone will each be considered a separate industry;

     2.   (For each Fund except the International Bond Fund) with respect to 75%
          of the Fund's assets, invest more than 5% of the Fund's assets (taken
          at a market value at the time of purchase) in the outstanding
          securities of any single issuer or own more than 10% of the

     3.   (For each Fund except Short Term Treasury Fund) borrow money or issue

     4.   Pledge, mortgage or hypothecate its assets other than to secure
          borrowings permitted by investment limitation 3 above (collateral

          for this purpose);

     5.   Make loans of securities to other persons in excess of 25% of a Fund's
          total assets and 33 1/3% of the Money Market Fund's total assets;

          limited partnerships, except securities issued by companies (including
          real estate investment trusts) that invest in real estate or interests
          therein.  The Real Estate Fund may not buy or sell real estate;
          however, this prohibition does not apply to the purchase or sale of
          (i) securities which are secured by real estate, (ii) securities
          representing interests in real estate, (iii) securities of companies
          operating in the real estate industry including real estate investment

     9.   Make investments for the purpose of exercising control or management;

          futures contracts and options on financial futures contracts, and
          options on securities and on securities, foreign currencies and on
          securities indices, as permitted by each Fund's prospectus.

     In addition, the Short Term Treasury Fund may not:

     1.   Borrow money or enter into reverse repurchase agreements except that
          the Fund may (i) borrow money or enter into reverse repurchase
          agreements for temporary purposes in amounts exceeding 5% of its total
          assets and (ii) borrow money for the purpose of meeting redemption
          requests, in 

                                      26
<PAGE>
 
          amounts (when aggregated with amounts borrowed under clause (i)) not
          exceeding 33 1/3% of its total assets;

     2.   Pledge, mortgage or hypothecate its assets other than to secure
          borrowings permitted by investment limitation 1 above; or

     3.   Issue any senior securities (as such term is defined in Section 18(f)
          of the 1940 Act) except to the extent the activities permitted by
          other enumerated investment limitations for the Company above may be
          deemed to give rise to a senior security.

     Additional investment restrictions adopted by each Fund of the Company,
which may be changed by the Board of Directors, provide that a Fund may not:

     1.   Invest more than 15% of its net assets (10% of net assets for the
          Money Market Fund) (taken at market value at the time of purchase) in
          securities which cannot be readily resold because of legal or
          contractual restrictions and (in the case of International Bond Fund
          and Short Term Treasury Fund only) which are not otherwise marketable;

     2.   (For each Fund except the International Bond Fund and Short Term
          Treasury Fund) own more than 10% (taken at market value at the time of
          purchase) of the outstanding voting securities of any single
          issuer;

     3.   (For each Fund except Short Term Treasury Fund) purchase or sell
          interests in oil, gas or other mineral exploration or development
          plans or leases); or

     4.   Invest in other investment companies except as permitted under the
          1940 Act.
    
     In addition, the International Bond Fund may not with respect to 50% of the
Fund's assets, invest more than 5% of the Fund's assets (taken at a market value
at the time of purchase) in the outstanding securities of any single issuer or
own more than 10% of the outstanding voting securities of any one issuer, in
each case other than securities issued or guaranteed by the U.S. Government, its
agencies or instrumentalities, at the close of each quarter of its taxable
year.     

     If a percentage limitation is satisfied at the time of investment, a later
increase or decrease in such percentage resulting from a change in the value of
a Fund's investments will not constitute a violation of such limitation, except
that any borrowing by a Fund that exceeds the fundamental investment limitations
stated above must be reduced to meet such limitations within the period required
by the 1940 Act (currently three days).  Otherwise, a Fund may continue to hold
a security even though it causes the Fund to exceed a percentage limitation
because of fluctuation in the value of the Fund's assets.

     No officer, director or employee of the Advisor, Sub-Advisor, Comerica
Incorporated ("Comerica"), the Sub-Custodian, the Distributor, the Administrator
or the Transfer Agent currently receives any compensation from the Trust,
Framlington or the Company. As of September 30, 1998, the Trustees and officers
of the Trust, as a group, owned less than 1% of all classes of outstanding
shares of the Funds of the Trust, the Trustees and officers of Framlington, as a
group, owned less than 1% of all classes of outstanding shares of the Funds of
Framlington except the Emerging Markets Fund in which Trustees and officers, as
a group, owned 1.051% of Class Y shares of the Fund, and the Directors and
officers of the Company, as a group, owned less than 1% of all classes of
outstanding shares of the Funds of the Company except Micro-Cap Fund, Money
Market Fund and the NetNet Fund in which the Directors and officers, as a group,
owned 2.218%, 1.700% and 2.400% of Class Y shares of those Funds, respectively.

     As of September 30, 1998, the Advisor and its affiliates, through common 
ownership, owned beneficially 11,492.654 Class Y shares of the Multi-Season 
Growth Fund, 47,585.780 Class Y shares of the NetNet Fund and 2,154,029.680 
Class Y shares of the Money Market Fund which represented less than 1%, 18.638% 
and 2.509% of the outstanding Class Y shares of those Funds, respectively.

     SHAREHOLDER AND TRUSTEE LIABILITY.  Under Massachusetts law, shareholders
of a business trust may, under certain circumstances, be held personally liable
for the obligations of the trust. However, the Trust's and Framlington's
Declaration of Trust, as amended, each provide that shareholders shall not be
subject to any personal liability in connection with the assets of the Trust or
Framlington for the acts or obligations of the Trust or Framlington, and that
every note, bond, contract, order or other undertaking made by the Trust or
Framlington shall contain a provision to the effect that the shareholders are
not personally liable thereunder. Each Declaration of Trust, as amended,
provides for indemnification out of the trust property of any shareholder held
personally liable solely by reason of his or her being or having been a
shareholder and not because of his or her acts or omissions or some other
reason. Each Declaration of Trust, as amended, also provides that the Trust and
Framlington shall, upon request, assume the defense of any claim made against
any shareholder for any act or obligation of the Trust or    

                                      31

Framlington, and shall satisfy any judgment thereon. Thus, the risk of a
shareholder's incurring financial loss on account of shareholder liability is
limited to circumstances in which the Trust or Framlington itself would be
unable to meet its obligations.

     Each Declaration of Trust, as amended, further provides that all persons
having any claim against the Trustees, the Trust or Framlington shall look
solely to the trust property for payment; that no Trustee of the Trust or
Framlington shall be personally liable for or on account of any contract, debt,
tort, claim, damage, judgment or decree arising out of or connected with the
administration or preservation of the trust property or the conduct of any
business of the Trust or Framlington; and that no Trustee shall be personally
liable to any person for any action or failure to act except by reason of his
own bad faith, willful misfeasance, gross negligence or reckless disregard of
his duties as a trustee.  With the exception stated, each Declaration of Trust,
as amended, provides that a Trustee is entitled to be indemnified against all
liabilities and expenses reasonably incurred by him in connection with the
defense or disposition of any proceeding in which he may be involved or with
which he may be threatened by reason of being or having been a Trustee, and that
the Trustees will indemnify officers, representatives and employees of the Trust
and Framlington to the same extent that Trustees are entitled to
indemnification.

              INVESTMENT ADVISORY AND OTHER SERVICE ARRANGEMENTS
                                            
     INVESTMENT ADVISOR AND SUB-ADVISOR.  The Advisor of each Fund is Munder
Capital Management, a Delaware general partnership.  The Advisor replaced
Woodbridge Capital Management, Inc. ("Woodbridge") as investment advisor to the
investment portfolios of the Trust and replaced Munder Capital Management, Inc.
as the investment advisor to the investment portfolios of the Company on January
31, 1995, upon the closing agreement (the "Joint Venture Agreement") among MCM,
Comerica, Woodbridge and WAM, pursuant to which MCM contributed its investment
advisory business and Comerica contributed the investment advisor business of
its indirect subsidiaries, Woodbridge and World Asset Management, to the
Advisor.  The general partners of the Advisor are WAM, WAM II, MCM and Munder
Group LLC.  WAM and WAM II are wholly-owned subsidiaries of Comerica Bank--Ann
Arbor, which in turn is a wholly-owned subsidiary of Comerica Incorporated, a
publicly-held bank holding company.   

     The Funds have entered into new Investment Advisory Agreements (the
"Advisory Agreements"), dated July 2, 1998, with the Advisor pursuant to terms
of an Exemptive Order (the "Order") granted by the SEC.  Under the terms of the
Order, the Advisory Agreements must be approved by the shareholders within one
hundred and fifty (150) days but no later than November 30, 1998.  The Funds
will call a special meeting of the shareholders to approve the Advisory
Agreements.  Until shareholder approval is obtained, the fees paid to the
Advisor will be paid into an escrow account.  If the Advisory Agreements are not
approved by the shareholders, the Board of Directors/Trustees will consider
appropriate action.

     Under the terms of the Advisory Agreements, the Advisor furnishes
continuing investment supervision to the Funds and is responsible for the
management of the Funds' portfolios. The responsibility for making decisions to
buy, sell or hold a particular security rests with the Advisor, subject to
review by the Trust's and the Company's Boards of Directors/Trustees. Under the
terms of the Advisory Agreement between the Advisor and Framlington, the Advisor
furnishes overall investment management for the Framlington Funds, provides
research and credit analysis, oversees the purchase and sale of portfolio
securities by the Sub-Advisor, maintains books and records with respect to the
Funds' securities transactions and provides periodic and special reports to the
Board of Trustees as requested.  

     Once the Advisory Agreements are approved by shareholders, they will
continue in effect for a period of two years from their effective dates.  If not
sooner terminated, each Advisory Agreement will continue in effect for
successive one year periods thereafter, provided that each continuance is
specifically approved annually by (a) the vote of a majority of the Boards of
Directors/Trustees who are not parties to the Advisory Agreement or interested
persons (as defined in the 1940 Act), cast in person at a meeting called for the
purpose of voting on such approval, and (b) either (i) the vote of a majority of
the outstanding voting securities of the affected Fund, or (ii) the vote of a
majority of the Boards of Directors/Trustees.  Each Advisory Agreement is
terminable with respect to a Fund by vote of the Boards of Directors/Trustees,
or by the holders of a majority of the outstanding voting securities of the
Fund, at any time without penalty, on 60 days' written notice to the Advisor.
The Advisor may also terminate its    

                                       32

advisory relationship with respect to a Fund without penalty on 90 days' written
notice to the Trust, Framlington or the Company, as applicable. Each Advisory
Agreement terminates automatically in the event of its assignment (as defined in
the 1940 Act).

     The Sub-Advisor is a subsidiary of Framlington Group Limited, which is
incorporated in England and Wales and, through its subsidiaries, provides a wide
range of investment services.  Framlington Group Limited is a wholly owned
subsidiary of Framlington Holdings Limited which is, in turn, owned 49% by the
Advisor and 51% by Credit Commercial de France S.A., a French banking
corporation listed on the Societe des Bourses Francaises.
    
     The Framlington Funds have entered into a new Sub-Advisory Agreement, dated
July 2, 1998, with the Advisor and the Sub-Advisor pursuant to terms of an
Exemptive Order (the "Order") granted by the SEC.  Under the terms of the Order,
the Sub-Advisory Agreement must be approved by the shareholders within one
hundred and fifty (150) days but no later than November 30, 1998.  The Funds
will call a special meeting of the shareholders to approve the Sub-Advisory
Agreement.  Until shareholder approval is obtained, the fees paid to the Sub-
Advisor will be paid into an escrow account.  If the Sub-Advisory Agreement is
not approved by the shareholders, the Board of Trustees will consider
appropriate action.  Under the terms of the Sub-Advisory Agreements, the Sub-
Advisor provides sub-advisory services to the Framlington Funds.  Subject to the
supervision of the Advisor, the Sub-Advisor is responsible for the management of
each Fund's portfolio, including decisions regarding purchases and sales of
portfolio securities by the Framlington Funds.  The Sub-Advisor is also
responsible for arranging the execution of portfolio management decisions,
including the selection of brokers to execute trades and the negotiation of
related brokerage commissions.     

     The Sub-Advisory Agreement, with respect to each Fund, will continue in
effect with respect to each Fund for a period of two years from its effective
date.  If not sooner terminated, the Sub-Advisory Agreement will continue in
effect for successive one year periods thereafter, provided that each
continuance is specifically approved annually by (a) the vote of a majority of
the Board of Trustees who are not parties to the Sub-Advisory Agreement or
interested persons (as defined in the 1940 Act), cast in person at a meeting
called for the purpose of voting on approval, and (b) either (i) with respect to
a Fund, the vote of a majority of the outstanding voting securities of that
Fund, or (ii) the vote of a majority of the Board of Trustees.  The Sub-Advisory
Agreement is terminable by vote of the Board of Trustees, or, with respect to a
Fund, by the holders of a majority of the outstanding voting securities of that
Fund, at any time without penalty, on 60 days' written notice to the Sub-
Advisor, or by the Advisor on 90 days' written notice to the Sub-Advisor.  The
Sub-Advisor may also terminate its sub-advisory relationship with a Fund without
penalty on 90 days' written notice to Framlington.  The Sub-Advisory Agreement
terminates automatically in the event of its assignment (as defined in the 1940
Act).

     DISTRIBUTION AGREEMENTS.  The Trust, Framlington and the Company have
entered into distribution agreements, under which the Distributor, as agent,
sells shares of each Fund on a continuous basis.  The Distributor has agreed to
use appropriate efforts to solicit orders for the purchase of shares of each
Fund, although it is not obligated to sell any particular amount of shares.  The
Distributor pays the cost of printing and distributing prospectuses to persons
who are not holders of shares of the Funds (excluding preparation and printing
expenses 

                                      35
<PAGE>
 
necessary for the continued registration of the shares) and of printing and
distributing all sales literature. The Distributor's principal offices are
located at 60 State Street, Boston, Massachusetts 02109.
    
     DISTRIBUTION SERVICES ARRANGEMENTS - CLASS A, CLASS B AND CLASS C SHARES.
Each Fund has adopted a Service and Distribution Plan with respect to its Class
A Shares pursuant to which it uses its assets to finance activities relating to
the provision of certain shareholder services.  Under the Service and
Distribution Plans for Class A Shares, the Distributor is paid an annual service
fee at the rate of up to 0.25% of the value of average daily net assets of the
Class A Shares of each Fund.  Each Fund has also adopted Service and
Distribution Plans with respect to its Class B and Class C Shares, pursuant to
which it uses its assets to finance activities relating to the distribution of
its shares to investors and provision of certain shareholder services.  Under
the Service and Distribution Plans for Class B and Class C Shares, the
Distributor is paid an annual service fee of up to 0.25% of the value of average
daily net assets of the Class B and Class C Shares of each Fund and an annual
distribution fee at the rate of up to 0.75% of the value of average daily net
assets of the Class B and Class C Shares of each Fund.

     Under the terms of the Service and Distribution Plans (collectively, the
"Plans"), each Plan continues from year to year, provided such continuance is
approved annually by vote of the Boards of Directors/Trustees, including a
majority of the Directors/Trustees who are not interested persons of the Trust,
Framlington or the Company, as applicable, and who have no direct or indirect
financial interest in the operation of that Plan (the "Non-Interested Plan
Directors").  The Plans may not be amended to increase the amount to be spent
for the services provided by the Distributor without shareholder approval, and
all amendments of the Plans also must be approved by the Directors/Trustees in
the manner described above.  Each Plan may be terminated at any time, without
penalty, by vote of a majority of the Non-Interested Plan Directors or by a vote
of a majority of the outstanding voting securities (as defined in the 1940 Act)
of the relevant class of the respective Fund on not more than 30 days' written
notice to any other party to the Plan.  Pursuant to each Plan, the Distributor
will provide the Boards of Directors/Trustees periodic reports of amounts
expended under the Plan and the purpose for which such expenditures were made.

     The Directors/Trustees have determined that the Plans will benefit the
Trust, Framlington, the Company and their respective shareholders by (i)
providing an incentive for broker or bank personnel to provide continuous
shareholder servicing after the time of sale; (ii) retaining existing accounts;
(iii) facilitating portfolio management flexibility through continued cash flow
into the Funds; and (iv) maintaining a competitive sales structure in the mutual
fund industry.

     With respect to Class B and Class C Shares of each Fund, the Distributor
expects to pay sales commissions to dealers authorized to sell a Fund's Class B
and Class C Shares at the time of sale.  The Distributor will use its own funds
(which may be borrowed) to pay such commissions pending reimbursement by the
relevant Plan.  In addition, the Advisor may use its own resources to make
payments to the Distributor or dealers authorized to sell the Funds' shares to
support their sales efforts.

FEES PAID TO THE DISTRIBUTOR PURSUANT TO CLASS A SERVICE PLANS.

*   Figures reflect period from commencement of operations through June 30, 
    1998.
**  As of June 30, 1998, the fund had not commenced selling Class C Shares.
+   As of June 2, 1998, Class C Shares of Short Term Treasury Fund were closed
    to all investments.     

   
     SHAREHOLDER SERVICING ARRANGEMENTS - CLASS K SHARES. As stated in each
Fund's Prospectus, Class K Shares are sold to investors through institutions
which enter into Shareholder Servicing Agreements with the Trust, Framlington or
the Company to provide support services to their Customers who beneficially own
Class K Shares in consideration of the Funds' payment of not more than 0.25% (on
an annualized basis) of the average daily net assets of the Class K Shares
beneficially owned by the Customers.

     Services provided by institutions under their service agreements may
include: (i) aggregating and processing purchase and redemption requests for
Class K Shares from Customers and placing net purchase and redemption orders
with the Distributor; (ii) providing Customers with a service that invests the
assets of their accounts in Class K Shares pursuant to specific or pre-
authorized instructions; (iii) processing dividend payments on behalf of
Customers; (iv) providing information periodically to Customers showing their
positions in Class K Shares; (v) arranging for bank wires; (vi) responding to
Customer inquiries relating to the services performed by the institutions; (vii)
providing subaccounting with respect to Class K Shares beneficially owned by
Customers or the information necessary for subaccounting; (viii) if required by
law, forwarding shareholder communications from the Trust, Framlington or the
Company (such as proxies, shareholder reports, annual and semi-annual financial
statements and dividend, distribution and tax notices) to Customers; (ix)
forwarding to Customers proxy statements and proxies containing any proposals
regarding the Trust's, Framlington's or the Company's arrangements with     

                                      42

institutions; and (x) providing such other similar services as the Trust,
Framlington or the Company may reasonably request to the extent the institutions
are permitted to do so under applicable statutes, rules and regulations.
    
     Pursuant to the Trust's, Framlington's and the Company's agreements with
such institutions, the Boards of Directors/Trustees will review, at least
quarterly, a written report of the amounts expended under Trust's, Framlington's
and the Company's agreements with institutions and the purposes for which the
expenditures were made.  In addition, the arrangements with institutions must be
approved annually by a majority of the Boards of Directors/Trustees, including a
majority of the Directors/Trustees who are not "interested persons" as defined
in the 1940 Act, and have no direct or indirect financial interest in such
arrangements.

     The Boards of Directors/Trustees have approved the arrangements with
institutions based on information provided by the service contractors that there
is a reasonable likelihood that the arrangements will benefit the Funds and
their shareholders by affording the Funds greater flexibility in connection with
the servicing of the accounts of the beneficial owners of their shares in an
efficient manner. 

     ADMINISTRATION AGREEMENT.  State Street Bank and Trust Company ("State

prepare and file various reports with the appropriate regulatory agencies; and
prepare various materials required by the SEC.  State Street may enter into an
agreement with one or more third parties pursuant to which such third parties
will provide administrative services on behalf of the Funds.

     Each Administration Agreement provides that the Administrator performing
services thereunder shall not be liable under the Agreement except for its bad
faith, negligence or willful misconduct in the performance of its duties and
obligations thereunder.

     CUSTODIAN, SUB-CUSTODIAN AND TRANSFER AGENCY AGREEMENTS.  Comerica Bank 
(the "Custodian"), whose principal business address is One Detroit Center, 500
Woodward Avenue, Detroit, MI 48226, is the custodian of each Fund pursuant to
custodian agreements with respectively the Trust, Framlington and the Company.
The Custodian receives no compensation for such services. State Street serves as
the sub-custodian to the Funds pursuant to sub-custodian agreements (each, a
"Sub-Custodian Contract") among the Custodian, State Street and respectively the
Company, the Trust and Framlington. State Street is also the sub-custodian with
respect to the custody of foreign securities held by the Funds. State Street has
in turn entered into additional agreements with financial institutions and
depositaries located in foreign countries with respect to the custody of such
securities. Under the Sub-Custodian Contracts, State Street (i) maintains a
separate account in the name of each Fund, (ii) holds and transfers portfolio
securities on account of each Fund, (iii) accepts receipts and makes
disbursements of money on behalf of each Fund, (iv) collects and receives all
income and other payments and distributions on account of each Fund's securities
and (v) makes periodic reports to the Boards of Directors/Trustees concerning
the Funds' operations.

     Prior to November 1, 1997, the Custodian was compensated for its services
as custodian.  For the period July 1, 1997 to October 31, 1997 the Custodian
earned $317,499.     
         
    
     Investor Services Group serves as the transfer and dividend disbursing
agent for the Funds pursuant to transfer agency agreements with the Trust,
Framlington and the Company, respectively, under which Investor Services Group
(i) issues and redeems shares of each Fund, (ii) addresses and mails all
communications by each Fund to its record owners, including reports to
shareholders, dividend and distribution notices and proxy materials for its
meetings of shareholders, (iii) maintains shareholder accounts, (iv) responds to
correspondence by shareholders of the Funds and (v) makes periodic reports to
the Boards Directors/Trustees concerning the operations of each Fund.

     COMERICA.  As stated in the Funds' Class K Shares Prospectus, Class K
Shares of the Funds are sold to customers of banks and other institutions.  Such
banks and institutions may include Comerica Incorporated (a publicly-held bank
holding company), its affiliates and subsidiaries ("Comerica") and other
institutions that have entered into agreements with the Company, the Trust and
Framlington providing for shareholder services for their customers.     

                                      44

     Banking laws and regulations currently prohibit a bank holding company
registered under the Federal Bank Holding Company Act of 1956 or any bank or
non-bank affiliate thereof from sponsoring, organizing, controlling or
distributing the shares of a registered, open-end investment company
continuously engaged in the issuance of its shares, and prohibit banks generally
from underwriting securities, but such banking laws and regulations do not
prohibit such a holding company or affiliate or banks generally from acting as
investment advisor, administrator, transfer agent or custodian to such an
investment company, or from purchasing shares of such a company as agent for and
upon the order of customers.  The Advisor and the Custodian are subject to such
banking laws and regulations.

     The Advisor and the Custodian believe they may perform the services for the
Trust, Framlington and the Company contemplated by their respective agreements
with each of them without violation of applicable banking laws and regulations.
It should be noted, however, that there have been no cases deciding whether bank
and non-bank subsidiaries of a registered bank holding company may perform
services comparable to those that are to be performed by these companies, and
future changes in either Federal or state statutes and regulations relating to
permissible activities of banks and their subsidiaries or affiliates, as well as
future judicial or administrative decisions or interpretations of current and
future statutes and regulations, could prevent these companies from continuing
to perform certain services for the Funds.

     Should future legislative, judicial or administrative action prohibit or
restrict the activities of such companies in connection with the provision of
services on behalf of the Trust, Framlington or the Company, the Trust,
Framlington or the Company might be required to alter materially or discontinue
the arrangements with the institutions and change the method of operations.  It
is not anticipated, however, that any change in the Funds' method of operations
would affect the net asset value per share of the Funds or result in a financial
loss to any shareholder of the Funds.

     It should be noted that future changes in either Federal or state statutes
and regulations relating to permissible activities of banks and their
subsidiaries or affiliates, as well as future judicial or administrative
decisions or interpretations of current and future statutes and regulations,
could prevent Comerica and certain other institutions from continuing to perform
certain services for Class K shares of the Funds.

     Should future legislative, judicial or administrative action prohibit or
restrict the activities of Comerica and/or other institutions in connection with
the provision of services on behalf of Class K shares of the Funds, the Trust,
Framlington or the Company might be required to alter materially or discontinue
the arrangements with the institutions and change the method of operations with
respect to Comerica and certain other institutions.  It is not anticipated,
however, that any change in the Funds' method of operations would affect the net
asset value per share of the Funds or result in a financial loss to any holder
of Class K shares of the Funds.

                            PORTFOLIO TRANSACTIONS
    
     Subject to the general supervision of the Boards of Directors/Trustees, the
Advisor or the Sub-Advisor, as the case may be, makes decisions with respect to
and places orders for all purchases and sales of portfolio securities for the
Funds.     

     Transactions on U.S. stock exchanges involve the payment of negotiated
brokerage commissions.  On exchanges on which commissions are negotiated, the
cost of transactions may vary among different brokers.  Transactions on foreign
stock exchanges involve payment for brokerage commissions which are generally
fixed.
    
     For the fiscal year ended June 30, 1998, the Funds paid brokerage 
commission as follows: $50,853.97 -Balanced Fund, $341,166.96 - Growth & Income
Fund, $19,135.67 - Index 500 Fund, $164,775.05 - International Equity Fund,

Healthcare Fund. For the period from commencement of operations through June 30,
1998, the Fund paid brokerage commission of $2,486.29 - Global Financial 
Services.

     For the fiscal year ended June 30, 1997, the Funds paid brokerage
commissions as follows: $54,221 -Balanced Fund, $336,161 - Growth & Income Fund,
$61,393 - Index 500 Fund, $155,081 - International Equity Fund, $366,346 -
Multi-Season Fund, $66,879 - Real Estate Fund and $355,997 - Small Company
Growth Fund.  The other Funds of the Company and the Trust did not pay brokerage
commissions during the fiscal year ended June 30, 1997.

     For the period from commencement of operations through June 30, 1997, the
Funds paid brokerage commissions as follows: $2,045 - Micro-Cap Fund, $82,304 -
Small-Cap Value Fund, $228,545 - Value Fund, $0 - International Bond Fund, $0 -
Short Term Treasury Fund, $43,256 - Emerging Markets Fund, $87,694 -
International Growth Fund and $3,325 - Healthcare Fund.

     For the fiscal year ended June 30, 1996, the Funds paid brokerage
commissions as follows: $52,376 -Balanced Fund, $202,292 - Growth & Income Fund,
$41,009 - Index 500 Fund, $428,699 - International Equity Fund, $424,580 -
Multi-Season Fund, $40,182 - Real Estate Fund and $203,936 - Small Company
Growth Fund.  The other Funds of the Company and the Trust did not pay brokerage
commissions during the fiscal year ended June 30, 1996.

     For the period from commencement of operations through June 30, 1996, the
Value Fund paid brokerage commissions of $169,335.     

         

     Over-the-counter issues, including corporate debt and government
securities, are normally traded on a "net" basis (i.e., without commission)
through dealers, or otherwise involve transactions directly with the issuer of
an instrument.  With respect to over-the-counter transactions, the Advisor or
the Sub-Advisor, as the case may be, will normally deal directly with dealers
who make a market in the instruments involved except in those circumstances
where more favorable prices and execution are available elsewhere.  The cost of
foreign and domestic securities purchased from underwriters includes an
underwriting commission or concession, and the prices at which securities are
purchased from and sold to dealers include a dealer's mark-up or mark-down.

     The Funds may participate, if and when practicable, in bidding for the
purchase of portfolio securities directly from an issuer in order to take
advantage of the lower purchase price available to members of a bidding group.
The Funds will engage in this practice, however, only when the Advisor or Sub-
Advisor, as the case may be, believes such practice to be in the Funds'
interests.

     Since the Money Market Funds will invest only in short-term debt
instruments, their annual portfolio turnover rates will be relatively high, but
brokerage commissions are normally not paid on money market instruments, and
portfolio turnover is not expected to have a material effect on the net
investment income of a Money Market Fund.  The portfolio turnover rate of a Fund
is calculated by dividing the lesser of a Fund's annual sales or purchases of
portfolio securities (exclusive of purchases or sales of securities whose
maturities at the time of acquisition were thirteen months or less for the Money
Market Funds or one year or less for the Equity and Bond Funds) by the monthly
average value of the securities held by the Fund during the year.  The Funds may
engage in short-term trading to achieve their investment objectives.  Portfolio
turnover may vary greatly from year to year as well as within a particular year.
    
     Each Fund's portfolio turnover rate is included in the prospectuses under
the section entitled "Financial Highlights." For the fiscal year ended June 30,
1998, the portfolio turnover rate for the Bond Fund and the Intermediate Bond
Fund was 222% and 194%, respectively.  The portfolio turnover of the Bond Fund
and the Intermediate Bond Fund was affected by fluctuating interest rate
conditions which at times required increased dispositions and acquisitions of
securities to maintain each Fund's maturity structure.

     In its Advisory Agreements, the Advisor (and, in the case of the
Framlington Funds, the Sub-Advisor pursuant to the Sub-Advisory Agreement)
agrees to select broker-dealers in accordance with guidelines established      

                                      46
<PAGE>
     
by the Boards of Directors/Trustees from time to time and in accordance with
applicable law. In assessing the terms available for any transaction, the
Advisor or Sub-Advisor, as the case may be, shall consider all factors it deems
relevant, including the breadth of the market in the security, the price of the
security, the financial condition and execution capability of the broker-dealer,
and the reasonableness of the commission, if any, both for the specific
transaction and on a continuing basis. In addition, the Advisory and Sub-
Advisory Agreements authorize the Advisor or Sub-Advisor, as the case may be,
subject to the prior approval of the Boards of Directors/Trustees, to cause the
Funds to pay a broker-dealer which furnishes brokerage and research services a
higher commission than that which might be charged by another broker-dealer for
effecting the same transaction, provided that the Advisor or Sub-Advisor, as the
case may be, determines in good faith that such commission is reasonable in
relation to the value of the brokerage and research services provided by such
broker-dealer, viewed in terms of either the particular transaction or the
overall responsibilities of the Advisor or Sub-Advisor to the Funds. Such
brokerage and research services might consist of reports and statistics on
specific companies or industries, general summaries of groups of bonds and their
comparative earnings and yields, or broad overviews of the securities markets
and the economy.     

     Supplementary research information so received is in addition to, and not
in lieu of, services required to be performed by the Advisor or Sub-Advisor, as
the case may be, and does not reduce the advisory fees payable to the Advisor or
Sub-Advisor by the Funds.  It is possible that certain of the supplementary
research or other services received will primarily benefit one or more other
investment companies or other accounts for which investment discretion is
exercised.  Conversely, a Fund may be the primary beneficiary of the research or
services received as a result of portfolio transactions effected for such other
account or investment company.

     Portfolio securities will not be purchased from or sold to the Advisor,
Sub-Advisor, Distributor or any affiliated person (as defined in the 1940 Act)
of the foregoing entities except to the extent permitted by SEC exemptive order
or by applicable law.
    
     Investment decisions for each Fund and for other investment accounts
managed by the Advisor or Sub-Advisor are made independently of each other in
the light of differing conditions.  However, the same investment decision may be
made for two or more of such accounts.  In such cases, simultaneous transactions
are inevitable.  Purchases or sales are then averaged as to price and allocated
as to amount in a manner deemed equitable to each such account.  While in some
cases this practice could have a detrimental effect on the price or value of the
security as far as a Fund is concerned, in other cases it is believed to be
beneficial to a Fund.  To the extent permitted by law, the Advisor or Sub-
Advisor, as the case may be, may aggregate the securities to be sold or
purchased for a Fund with those to be sold or purchased for other investment
companies or accounts in executing transactions.

     A Fund will not purchase securities during the existence of any
underwriting or selling group relating to such securities of which the Advisor,
Sub-Advisor or any affiliated person (as defined in the 1940 Act) thereof is a
member except pursuant to procedures adopted by the Trust's or Framlington Board
of Trustees or the Company's Board of Directors in accordance with Rule 10f-3
under the 1940 Act.

     The Trust, the Company and Framlington are required to identify the
securities of their regular brokers or dealers (as defined in Rule 10b-1 under
the 1940) Act or their parent companies held by them as of the close of their
most recent fiscal year and state the value of such holdings.  As of June 30,

     Except as noted in the Prospectuses and this Statement of Additional
Information the Funds' service contractors bear all expenses in connection with
the performance of their services and the Funds bear the expenses incurred in
their operations.  These expenses include, but are not limited to, fees paid to
the Advisor, Sub-Advisor, Administrator, Custodian, Sub-Custodian and Transfer
Agent; fees and expenses of officers and Boards of Directors/Trustees; taxes;
interest; legal and auditing fees; brokerage fees and commissions; certain fees
and expenses in registering and qualifying the Fund and its shares for
distribution under Federal and state securities laws; expenses of preparing
prospectuses and statements of additional information and of printing and
distributing prospectuses and statements of additional information to existing
shareholders; the expense of reports to shareholders, shareholders' meetings and
proxy solicitations; fidelity bond and directors' and officers' liability
insurance premiums; and the expense of using independent pricing services.  Any
general expenses of the Trust, Framlington or the Company that are not readily
identifiable as belonging to a particular investment portfolio of the Trust,
Framlington or the Company are allocated among all investment portfolios of the
Trust, Framlington or the Company by or under the direction of the Boards of
Directors/Trustees in a manner that the Boards determine to be fair and
equitable.  The Advisor, Sub-Advisor, Administrator, Custodian, Sub-Custodian
and Transfer Agent may voluntarily waive all or a portion of their respective
fees from time to time.     

                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION
       
     
     PURCHASES.  As described in the Prospectuses, shares of the Funds may be
purchased in a number of different ways.  Such alternative sales arrangements
permit an investor to choose the method of purchasing shares that is most
beneficial depending on the amount of the purchase, the length of time the
investor expects to hold shares and other relevant circumstances.  An investor
may place orders directly through the Transfer Agent or the Distributor or
through arrangements with his/her authorized broker.     

     RETIREMENT PLANS.  Shares of any of the Funds may be purchased in
connection with various types of tax deferred retirement plans, including
individual retirement accounts ("IRAs"), qualified plans, deferred compensation
for public schools and charitable organizations (403(b) plans) and simplified
employee pension IRAs.  An individual or organization considering the
establishment of a retirement plan should consult with an attorney and/or an
accountant with respect to the terms and tax aspects of the plan.  A $10.00
annual custodial fee is also charged on IRAs.  This custodial fee is due by
December 15 of each year and may be paid by check or shares liquidated from a
shareholder's account.

     REDEMPTIONS.  As described in the Fund's Prospectuses, shares of the Funds
may be redeemed in a number of different ways:

     .   By Mail
     .   By Telephone
     .   Automatic Withdrawal Plan

The redemption price for Fund shares is the net asset value next determined
after receipt of the redemption request in proper order.  The redemption
proceeds will be reduced by the amount of any applicable contingent deferred
sales charge ("CDSC").

     CONTINGENT DEFERRED SALES CHARGE - CLASS B SHARES.  Class B Shares redeemed
within six years of purchase are subject to a CDSC.  The CDSC is based on the
original net asset value at the time of investment or the net asset value at the
time of redemption, whichever is lower.

                                      48

     CDSC WAIVERS - CLASS B SHARES OF THE TRUST FUNDS PURCHASED ON OR BEFORE
JUNE 27, 1995. The CDSC will be waived with respect to Class B Shares of the
Trust Funds purchased on or before June 27, 1995 in the following circumstances:

     (1)  total or partial redemptions made within one year following the death
          or disability of a shareholder or registered joint owner;
     (2)  minimum required distributions made in connection with an IRA or other
          retirement plan following attainment of age 59 1/2; and
     (3)  redemptions pursuant to a Fund's right to liquidate a shareholder's
          account involuntarily.

     CDSC WAIVERS - CLASS B SHARES OF THE COMPANY FUNDS PURCHASED ON OR BEFORE
JUNE 27, 1995.  The CDSC will be waived on the following types of redemptions
with respect to Class B Shares of the Company Funds purchased on or before June
27, 1995:

     (1)  redemptions by investors who have invested a lump sum amount of $1
          million or more in the Fund;
     (2)  redemptions by the officers, directors, and employees of the Advisor
          or the Distributor and such persons' immediate families;
     (3)  dealers or brokers who have a sales agreement with the Distributor,
          for their own accounts, or for retirement plans for their employees or
          sold to registered representatives or full time employees (and their
          families) that certify to the Distributor at the time of purchase that
          such purchase is for their own account (or for the benefit of their
          families);
     (4)  involuntary redemptions effected pursuant to the Fund's right to
          liquidate shareholder accounts having an aggregate net asset value of
          less than $250; and
     (5)  redemptions the proceeds of which are reinvested in the Fund within 90
          days of the redemption.

     CONTINGENT DEFERRED SALES CHARGE - CLASS A AND CLASS C SHARES.  The
Prospectuses describe the CDSC for Class A or C Shares of the Funds of the
Trust, the Company and Framlington purchased after June 27, 1995.

     Class A Shares of the Trust Funds purchased on or before June 27, 1995
without a sales charge by reason of a purchase of $500,000 or more are subject
to a CDSC of 1.00% of the lower of the original purchase price or the net asset
value at the time of redemption if such shares are redeemed within two years of
the date of purchase.  Class A Shares of the Trust Funds purchased on or before
June 27, 1995 that are redeemed will not be subject to the CDSC to the extent
that the value of such shares represents: (1) reinvestment of dividends or other
distributions; (2) Class A Shares redeemed more than two years after their
purchase; (3) a minimum required distribution made in connection with IRA or
other retirement plans following attainment of age 59 1/2; or (4) total or
partial redemptions made within one year following the death or disability of a
shareholder or registered joint owner.

                                       49
<PAGE>
 
     No CDSC is imposed to the extent that the current net asset value of the
shares redeemed does not exceed (a) the current net asset value of shares
purchased through reinvestment of dividends or capital gain distributions plus
(b) the current net asset value of shares purchased more than one year prior to
the redemption, plus (c) increases in the net asset value of the shareholder's
shares above the purchase payments made during the preceding one year.
    
     The holding period of Class A or Class C Shares of a Fund acquired through
an exchange of the corresponding class of shares of the Munder Money Market Fund
(which are available only by exchange of Class A or Class C Shares of the Fund,
as the case may be) and the Company Funds, the Framlington Funds and the non-
money market funds of the Trust will be calculated from the date that the Class
A or Class C Shares of the Fund were initially purchased.      

     In determining whether a CDSC is applicable to a redemption, the
calculation will be made in a manner that results in the lowest possible rate.
It will be assumed that the redemption is made first of amounts representing all
Class A Shares on which a front-end sales charge has been assessed; then of
shares acquired pursuant to the reinvestment of dividends and distributions; and
then of amounts representing the cost of shares purchased one year or more prior
to the redemption.
    
     OTHER REDEMPTION INFORMATION.  Redemption proceeds are normally paid in
cash; however, each Fund may pay the redemption price in whole or part by a
distribution in kind of securities from the portfolio of the particular Fund, in
lieu of cash, in conformity with applicable rules of the SEC.  If shares are
redeemed in kind, the redeeming shareholder might incur transaction costs in
converting the assets into cash.  The Funds are obligated to redeem shares
solely in cash up to the lesser of $250,000 or 1% of its net assets during any
90-day period for any one shareholder.      

     The Funds reserve the right to suspend or postpone redemptions during any
period when: (i) trading on the New York Stock Exchange (the "NYSE") is
restricted by applicable rules and regulations of the SEC; (ii) the NYSE is
closed for other than customary weekend and holiday closings; (iii) the SEC has
by order permitted such suspension or postponement for the protection of the
shareholders; or (iv) an emergency, as determined by the SEC, exists, making
disposal of portfolio securities or valuation of net assets of a Fund not
reasonably practicable.

     The Funds may involuntarily redeem an investor's shares if the net asset
value of such shares is less than $250; provided that involuntary redemptions
will not result from fluctuations in the value of an investor's shares.  A
notice of redemption, sent by first-class mail to the investor's address of
record, will fix a date not less than 30 days after the mailing date, and shares
will be redeemed at the net asset value at the close of business on that date
unless sufficient additional shares are purchased to bring the aggregate account
value up to $250 or more.  A check for the redemption proceeds payable to the
investor will be mailed to the investor at the address of record.

     EXCHANGES.  In addition to the method of exchanging shares described in the
Funds' Prospectuses, a shareholder exchanging at least $1,000 of shares (for
which certificates have not been issued) and who has authorized expedited
exchanges on the application form filed with the Transfer Agent may exchange
shares by telephoning the Funds at (800) 438-5789.  Telephone exchange
instructions must be received by the Transfer Agent by 4:00 p.m., Eastern time.
The Funds, Distributor and Transfer Agent reserve the right at any time to
suspend or terminate the expedited exchange procedure or to impose a fee for
this service.  During periods of unusual economic or market changes,
shareholders may experience difficulties or delays in effecting telephone
exchanges.  Neither the Funds nor the Transfer Agent will be responsible for any
loss, damages, expense or cost arising out of any telephone exchanges effected
upon instructions believed by them to be genuine.  The Transfer Agent has
instituted procedures that it believes are reasonably designed to insure that
exchange instructions communicated by telephone are genuine, and could be liable
for losses caused by unauthorized or fraudulent instructions in the absence of
such procedures.  The procedures currently include a recorded verification of
the shareholder's name, social security number and account number, followed by
the mailing of a statement confirming the transaction, which is sent to the
address of record.

                                NET ASSET VALUE
                                        
     MONEY MARKET FUNDS.  The value of the portfolio securities of the Money
Market Funds is calculated using the amortized cost method of valuation.  Under
this method the market value of an instrument is approximated by amortizing the
difference between the acquisition cost and value at maturity of the instrument
on a straight-line basis over the remaining life of the instrument.  The effect
of changes in the market value of a security as a result of fluctuating interest
rates is not taken into account.  The market value of debt securities usually
reflects yields generally available on securities of similar quality.  When such
yields decline, market values can be expected to increase, and when yields
increase, market values can be expected to decline.
    
     As indicated, the amortized cost method of valuation may result in the
value of a security being higher or lower than its market price, the price a
Fund would receive if the security were sold prior to maturity.  The Boards of
Directors/Trustees have established procedures reasonably designed, taking into
account current market conditions and the Funds' investment objectives, for the
purpose of maintaining a stable net asset value of $1.00 per share for each
Money Market Fund for purposes of sales and redemptions.  These procedures
include a review by the Boards of Directors/Trustees, at such intervals as they
deem appropriate, of the extent of any deviation of net asset value per share,
based on available market quotations, from the $1.00 amortized cost per share.
Should that deviation exceed 1/2 of 1% for a Fund, the Boards of
Directors/Trustees will promptly consider whether any and, if any, what action
should be initiated.  If the Board believes that the extent of any deviation
from a Money Market Fund's $1.00 amortized cost price per share may result in
material dilution of other unfair results to new or existing investors, it will
take such steps as it considers appropriate to eliminate or reduce any such
dilution or unfair results to the extent reasonably practicable.  Such action
may include redeeming shares in kind, selling portfolio securities prior to
maturity, reducing or withholding dividends, shortening the average portfolio
maturity, reducing the number of outstanding shares without monetary
consideration, and utilizing a net asset value per share as determined by using
available market quotations.

     Pursuant to Rule 2a-7 under the 1940 Act, each of the Money Market Funds
will maintain a dollar-weighted average portfolio maturity appropriate to its
objective of maintaining a stable net asset value per share, provided that such
Funds will not purchase any security with a remaining maturity (within the
meaning of Rule 2a-7 under the 1940 Act) greater than 397 days (securities
subject to repurchase agreements, variable and floating rate securities, and
certain other securities may bear longer maturities), nor maintain a dollar-
weighted average portfolio maturity which exceeds 90 days.  In addition, the
Funds may acquire only U.S. dollar denominated obligations that present minimal
credit risks and that are "First Tier Securities" at the time of investment.
First Tier Securities are those that are rated in the highest rating category by
at least two nationally recognized security rating organizations NRSROs or by
one if it is the only NRSRO rating such obligation or, if unrated, determined to
be of comparable quality.  A security is deemed to be rated if the issuer has
any security outstanding of comparable priority and security which has received
a short-term rating by an NRSRO.  The Advisor will determine that an obligation
presents minimal credit risks or that unrated investments are of comparable
quality, in accordance with guidelines established by the Board of
Directors/Trustees.  There can be no assurance that a constant net asset value
will be maintained for each Money Market Fund.

     ALL FUNDS.  In determining the approximate market value of portfolio
investments, the Trust, Framlington or the Company may employ outside
organizations, which may use matrix or formula methods that take into
consideration market indices, matrices, yield curves and other specific
adjustments.  This may result in the securities being valued at a price
different from the price that would have been determined had the matrix or
formula methods not been used.  All cash, receivables and current payables are
carried on the Trust's, Framlington's or the Company's books at their face
value.  Other assets, if any, are valued at fair value as determined in good
faith under the supervision of the Board members.      

IN-KIND PURCHASES

     With the exception of the Real Estate Fund, payment for shares may, in the
discretion of the Advisor, be made in the form of securities that are
permissible investments for the Funds as described in the Prospectuses. 

                                       51
<PAGE>

     
Shares of the Real Estate Fund will not be issued for consideration other than
cash. For further information about this form of payment please contact the
Transfer Agent. In connection with an in-kind securities payment, a Fund will
require, among other things, that the securities (a) meet the investment
objectives and policies of the Fund; (b) are acquired for investment and not for
resale; (c) are liquid securities that are not restricted as to transfer either
by law or liquidity of markets; (d) have a value that is readily ascertainable
by a listing on a nationally recognized securities exchange; and (e) are valued
on the day of purchase in accordance with the pricing methods used by the Fund
and that the Fund receive satisfactory assurances that (i) it will have good and
marketable title to the securities received by it; (ii) that the securities are
in proper form for transfer to the Fund; and (iii) adequate information will be
provided concerning the basis and other tax matters relating to the securities.
                                                                                

                            PERFORMANCE INFORMATION

YIELD OF THE MONEY MARKET FUNDS
    
     The Money Market Funds' current and effective yields are computed using
standardized methods required by the SEC.  The annualized yield is computed by:
(a) determining the net change in the value of a hypothetical account having a
balance of one share at the beginning of a seven-calendar day period; (b)
dividing the net change by the value of the account at the beginning of the
period to obtain the base period return; and (c) annualizing the results (i.e.,
multiplying the base period return by 365/7).  The net change in the value of
the account reflects the value of additional shares purchased with dividends
declared and all dividends declared on both the original share and such
additional shares, but does not include realized gains and losses or unrealized
appreciation and depreciation.  Compound effective yields are computed by adding
1 to the base period return (calculated as described above), raising the sum to
a power equal to 365/7 and subtracting 1.  Based on the foregoing computations,
the table below shows the annualized yields for all share classes of the Cash
Investment, Money Market, Tax-Free Money Market and U.S. Treasury Money Market
Funds for the seven-day period ended June 30, 1998.

     In addition, a standardized "tax-equivalent yield" may be quoted for the
Tax-Free Money Market Fund, which is computed by: (a) dividing the portion of
the Fund's yield (as calculated above) that is exempt from Federal income tax by
1 minus a stated Federal income tax rate; and (b) adding the figure resulting
from (a) above to that portion, if any, of the yield that is not exempt from
Federal income tax.  For the seven-day period ended June 30, 1998, the tax-
equivalent yield for Class A, Class K and Class Y Shares of the Tax-Free Money
Market Fund was 3.97% (Class A), 4.11% (Class K) and 4.33% (Class Y) calculated
for all share classes based on a stated tax rate of 31%.  The fees which may be
imposed by institutions on their Customers are not reflected in the calculations
of yields for the Funds.      

     Yield may fluctuate daily and does not provide a basis for determining
future yields.  Because the yields of each Fund will fluctuate, they cannot be
compared with yields on savings accounts or other investment alternatives that
provide an agreed to or guaranteed fixed yield for a stated period of time.
However, yield information may be useful to an investor considering temporary
investments in money market instruments.  In comparing the yield of one money
market fund to another, consideration should be given to each Fund's investment
policies including the 

                                       52

types of investments made, lengths of maturities of the portfolio securities,
and whether there are any special account charges which may reduce the effective
yield.
    

PERFORMANCE OF THE NON-MONEY MARKET FUNDS

     YIELD.  The Bond Funds', International Bond Fund's and Short Term Treasury
Fund's 30-day (or one month) standard yield described in the applicable
Prospectus is calculated for each Fund in accordance with the method prescribed
by the SEC for mutual funds:      

                         YIELD = 2 [(a-b + 1)/6/ - 1]
                                     ---             
                                      cd
Where:
     a =dividends and interest earned by a Fund during the period;
     b =expenses accrued for the period (net of reimbursements and waivers);
     c =average daily number of shares outstanding during the period entitled to
        receive dividends;
     d =maximum offering price per share on the last day of the period.

     For the purpose of determining interest earned on debt obligations
purchased by a Fund at a discount or premium (variable "a" in the formula), each
Fund computes the yield to maturity of such instrument based on the market value
of the obligation (including actual accrued interest) at the close of business
on the last business day of each month, or, with respect to obligations
purchased during the month, the purchase price (plus actual accrued interest).
Such yield is then divided by 360 and the quotient is multiplied by the market
value of the obligation (including actual accrued interest) in order to
determine the interest income on the obligation for each day of the subsequent
month that the obligation is in the portfolio.  It is assumed in the above
calculation that each month contains 30 days.  The maturity of a debt obligation
with a call provision is deemed to be the next call date on which the obligation
reasonably may be expected to be called or, if none, the maturity date.  For the
purpose of computing yield on equity securities held by a Fund, dividend income
is recognized by accruing 1/360 of the stated dividend rate of the security for
each day that the security is held by the Fund.

     Interest earned on tax-exempt obligations that are issued without original
issue discount and have a current market discount is calculated by using the
coupon rate of interest instead of the yield to maturity.  In the case of tax-
exempt obligations that are issued with original issue discount but which have
discounts based on current market value that exceed the then-remaining portion
of the original issue discount (market discount), the yield to maturity is the
imputed rate based on the original issue discount calculation.  On the other
hand, in the case of tax-exempt obligations that are issued with original issue
discount but which have the discounts based on current market value that are
less than the then-remaining portion of the original issue discount (market
premium), the yield to maturity is based on the market value.
    
     With respect to mortgage or other receivables-backed debt obligations
purchased at a discount or premium, the formula generally calls for amortization
of the discount or premium.  The amortization schedule will be adjusted monthly
to reflect changes in the market value of such debt obligations.  Expenses
accrued for the period (variable "b" in the formula) include all recurring fees
charged by a Fund to all shareholder accounts in proportion to the length of the
base period and the Fund's mean (or median) account size.  Undeclared earned
income will be subtracted from the offering price per share (variable "d" in the
formula).  A Fund's maximum offering price per share for purposes of the formula
includes the maximum sales charge imposed -- currently 5.50% of the per share
offering price for Class A Shares of the Equity Funds (with the exception of the
Index 500 Fund, currently 2.50% of the per share offering price for Class A) and
the Balanced Fund and 4.00% of the per share offering price for Class A Shares
of the Bond Fund, International Bond Fund, Short Term Treasury Fund and Tax-Free
Bond Funds.  The tax-equivalent yield for each Tax-Free Bond Fund below is based
on a stated federal tax rate of 31% and, with respect to Michigan Bond Fund, a
Michigan state tax rate of 4%.

     TOTAL RETURN.  Each Fund that advertises its "average annual total return"
computes such return by determining the average annual compounded rate of return
during specified periods that equates the initial amount invested to the ending
redeemable value of such investment according to the following formula:     

                              P (1 + T)/n/ = ERV
Where:
    
     P = hypothetical initial payment of $1,000;

     T = average annual total return;

     n = period covered by the computation, expressed in years; and

     ERV = ending redeemable value of a hypothetical $1,000 payment made at the
     beginning of the 1, 5 or 10 year (or other) periods at the end of the
     applicable period (or a fractional portion thereof).     
 
         

     Each Fund that advertises its "aggregate total return" computes such
returns by determining the aggregate compounded rates of return during specified
periods that likewise equate the initial amount invested to the ending
redeemable value of such investment.  The formula for calculating aggregate
total return is as follows:

                                   (ERV) - 1
                                   -----    
                     Aggregate Total Return = P

                                      55
<PAGE>
 
     The calculations are made assuming that (1) all dividends and capital gain
distributions are reinvested on the reinvestment dates at the price per share
existing on the reinvestment date, (2) all recurring fees charged to all
shareholder accounts are included, and (3) for any account fees that vary with
the size of the account, a mean (or median) account size in the Fund during the
periods is reflected.  The ending redeemable value (variable "ERV" in the
formula) is determined by assuming complete redemption of the hypothetical
investment after deduction of all non-recurring charges at the end of the
measuring period.  The Funds' average annual total return and load adjusted
aggregate total return quotations for Class A Shares will reflect the deduction
of the maximum sales charge charged in connection with the purchase of such
shares  currently 5.50% of the per share offering price for Class A Shares of
the Equity Funds (with the exception of the Index 500 Fund, currently 2.50% of
the per share offering price for Class A) and the Balanced Fund and 4.00% of the
per share offering price for Class A Shares of the Bond Fund, International Bond
Fund and Tax-Free Bond Funds; and the Funds' load adjusted average annual total
return and load adjusted aggregate total return quotations for Class B Shares
will reflect any applicable CDSC; provided that the Funds may also advertise
total return data without reflecting any applicable CDSC sales charge imposed on
the purchase of Class A Shares or Class B Shares in accordance with the views of
the SEC.  Quotations which do not reflect the sales charge will, of course, be
higher than quotations which do.

     Based on the foregoing calculation, set forth below are the average annual
total return figures for the Class A, B, C, K and Y Shares of each of the
following Funds for the 12 month and 5 year periods ended June 30, 1998 and

     ALL FUNDS.  The performance of any investment is generally a function of
portfolio quality and maturity, type of investment and operating expenses.

     From time to time, in advertisements or in reports to shareholders, a
Fund's yields or total returns may be quoted and compared to those of other
mutual funds with similar investment objectives and to stock or other relevant
indices.  For example, a Fund's yield may be compared to the IBC/Donoghue's
Money Fund Average, which is an average compiled by Donoghue's MONEY FUND REPORT
of Holliston, MA 01746, a widely recognized independent publication that
monitors the performance of money market funds, or to the data prepared 

                                      59
<PAGE>
 
by Lipper Analytical Services, Inc., a widely recognized independent service
that monitors the performance of mutual funds. In addition, as stated in the
Funds' Prospectuses, the tax-equivalent yield (and hypothetical examples
illustrating the effect of tax-equivalent yields) of a Fund may be quoted in
advertisements or reports to shareholders. Hypothetical examples showing the
difference between a taxable and a tax-free investment may also be provided to
shareholders.

                                     TAXES
    
     The following summarizes certain additional federal and state income tax
considerations generally affecting the Funds and their shareholders that are not
described in the Funds' Prospectuses.  No attempt is made to present a detailed
explanation of the tax treatment of the Funds or their shareholders, and the
discussion here and in the applicable Prospectus is not intended as a substitute
for careful tax planning.  This discussion is based upon present provisions of
the Internal Revenue Code, the regulations promulgated thereunder, and judicial
and administrative ruling authorities, all of which are subject to change, which
change may be retroactive.  Prospective investors should consult their own tax
advisors with regard to the federal tax consequences of the purchase, ownership
and disposition of Fund shares, as well as the tax consequences arising under
the laws of any state, foreign country, or other taxing jurisdiction.

     GENERAL.  Each Fund intends to elect and qualify to be taxed separately as
a regulated investment company under the Internal Revenue Code.  As a regulated
investment company, each Fund generally is exempt from federal income tax on its
net investment income and realized capital gains which it distributes to
shareholders, provided that it distributes an amount equal to the sum of (a) at
least 90% of its investment company taxable income (net investment income and
the excess of net short-term capital gain over net long-term capital loss), if
any, for the year and (b) at least 90% of its net tax-exempt interest income, if
any, for the year (the "Distribution Requirement") and satisfies certain other
requirements of the Internal Revenue Code that are described below.
Distributions of investment company taxable income and net tax-exempt interest
income made during the taxable year or, under specified circumstances, within
twelve months after the close of the taxable year will satisfy the Distribution
Requirement.      

     In addition to satisfaction of the Distribution Requirement, each Fund must
derive with respect to a taxable year at least 90% of its gross income from
dividends, interest, certain payments with respect to securities loans and gains
from the sale or other disposition of stock or securities or foreign currencies,
or from other income derived with respect to its business of investing in such
stock, securities, or currencies (the "Income Requirement").  Interest
(including original issue discount and "accrued market discount") received by a
Fund at maturity or on disposition of a security held for less than three months
will not be treated (in contrast to other income which is attributable to
realized market appreciation) as gross income from the sale or other disposition
of securities held for less than three months for this purpose.

     In addition to the foregoing requirements, at the close of each quarter of
its taxable year, at least 50% of the value of each Fund's assets must consist
of cash and cash items, U.S. Government securities, securities of other
regulated investment companies, and securities of other issuers (as to which a
Fund has not invested more than 5% of the value of its total assets in
securities of such issuer and as to which a Fund does not hold more than 10% of
the outstanding voting securities of such issuer) and no more than 25% of the
value of each Fund's total assets may be invested in the securities of any one
issuer (other than U.S. Government securities and securities of other regulated
investment companies), or in two or more issuers which such Fund controls and
which are engaged in the same or similar trades or businesses.

     Distributions of net investment income received by a Fund from investments
in debt securities (other than interest on tax-exempt municipal obligations held
by the Tax-Free Bond Funds and Tax-Free Money Market Fund) and any net realized
short-term capital gains distributed by a Fund will be taxable to shareholders
as ordinary income and will not be eligible for the dividends received deduction
for corporations.

     Each Fund intends to distribute to shareholders any excess of net long-term
capital gain over net short-term capital loss ("net capital gain") for each
taxable year.  Such gain is distributed as a capital gain dividend and is

                                       60
<PAGE>
 
taxable to shareholders as gain from the sale or exchange of a capital asset
held for more than one year, regardless of the length of time a shareholder has
held his or her Fund shares and regardless of whether the distribution is paid
in cash or reinvested in shares.  The Funds expect that capital gain dividends
will be taxable to shareholders as long-term gain.  Capital gain dividends are
not eligible for the dividends received deduction.

     In the case of corporate shareholders, distributions of a Fund for any
taxable year generally qualify for the dividends received deduction to the
extent of the gross amount of "qualifying dividends" received by such Fund for
the year and if certain holding period requirements are met.  Generally, a
dividend will be treated as a "qualifying dividend" if it has been received from
a domestic corporation.

     If for any taxable year any Fund does not qualify as a regulated investment
company, all of its taxable income will be subject to tax at regular corporate
rates without any deduction for distributions to shareholders.  In such event,
all distributions (whether or not derived from exempt-interest income) would be
taxable as ordinary income and would be eligible for the dividends received
deduction in the case of corporate shareholders to the extent of such Fund's
current and accumulated earnings and profits.

     Shareholders will be advised annually as to the federal income tax
consequences of distributions made by the Funds each year.

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

     Although a Fund expects to qualify as a "regulated investment company" and
to be relieved of all or substantially all Federal income taxes, depending upon
the extent of its activities in states and localities in which its offices are
maintained, in which its agents or independent contractors are located or in
which it is otherwise deemed to be conducting business, a Fund may be subject to
the tax laws of such states or localities.

     The Trust, the Framlington Trust and the Company will be required in
certain cases to withhold and remit to the United States Treasury 31% of taxable
distributions, including gross proceeds realized upon sale or other dispositions
paid to any shareholder (i) who has provided an incorrect tax identification
number or no number at all, (ii) who is subject to backup withholding by the
Internal Revenue Service for failure to report the receipt of taxable interest
or dividend income properly, or (iii) who has failed to certify that he is not
subject to backup withholding or that he is an "exempt recipient."

     DISPOSITION OF SHARES.  Upon a redemption, sale or exchange of his or her
shares, a shareholder will realize a taxable gain or loss depending upon his or
her basis in the shares.  Such gain or loss will be treated as capital gain or
loss if the shares are capital assets in the shareholder's hands and will be
long-term or short-term, generally, depending upon the shareholder's holding
period for the shares.  Any loss realized on a redemption, sale or exchange will
be disallowed to the extent the shares disposed of are replaced (including
through reinvestment of dividends) within a period of 61 days beginning 30 days
before and ending 30 days after the shares are disposed of.  In such a case, the
basis of the shares acquired will be adjusted to reflect the disallowed loss.
Any loss realized by a shareholder on the sale of Fund shares held by the
shareholder for six months or less will be treated as a long-term capital loss
to the extent of any distributions of net capital gains received or treated as
having been received by the shareholder with respect to such shares and treated
as long-term capital gains.  Furthermore, a loss realized by a 

                                       61
<PAGE>
 
shareholder on the redemption, sale or exchange of shares of a Fund with respect
to which exempt-interest dividends have been paid will, to the extent of such
exempt-interest dividends, be disallowed if such shares have been held by the
shareholder for six months or less.

     In some cases, shareholders will not be permitted to take sales charges
into account for purposes of determining the amount of gain or loss realized on
the disposition of their stock.  This prohibition generally applies where (1)
the shareholder incurs a sales charge in acquiring the stock of a Fund, (2) the
stock is disposed of before the 91st day after the date on which it was
acquired, and (3) the shareholder subsequently acquires the stock of the same or
another fund and the otherwise applicable sales charge is reduced under a
"reinvestment right" received upon the initial purchase of regulated investment
company shares.  The term "reinvestment right" means any right to acquire stock
of one or more funds without the payment of a sales charge or with the payment
of a reduced sales charge.  Sales charges affected by this rule are treated as
if they were incurred with respect to the stock acquired under the reinvestment
right.  This provision may be applied to successive acquisitions of Fund shares.

     Although each Fund expects to qualify as a "regulated investment company"
and to be relieved of all or substantially all federal income taxes, depending
upon the extent of its activities in states and localities in which its offices
are maintained, in which its agents or independent contractors are located or in
which it is otherwise deemed to be conducting business, each Fund may be subject
to the tax laws of such states or localities.

     TAX-FREE BOND FUNDS AND TAX-FREE MONEY MARKET FUND.  The Michigan Bond
Fund, Tax-Free Bond Fund, Tax-Free Intermediate Bond Fund, and Tax-Free Money
Market Fund are designed to provide investors with current tax-exempt interest
income.  Shares of the Funds would not be suitable for tax-exempt institutions
and may not be suitable for retirement plans qualified under Section 401 of the
Code, H.R. 10 plans and individual retirement accounts since such plans and
accounts are generally tax-exempt and, therefore, not only would not gain any
additional benefit from the Funds' dividends being tax-exempt but also such
dividends would be taxable when distributed to the beneficiary.  In addition,
the Funds may not be an appropriate investment for entities which are
"substantial users" of facilities financed by private activity bonds or "related
persons" thereof.  "Substantial user" is defined under U.S. Treasury Regulations
to include a non-exempt person who regularly uses a part of such facilities in
his trade or business and (a) whose gross revenues derived with respect to the
facilities financed by the issuance of bonds are more than 5% of the total
revenues derived by all users of such facilities, (b) who occupies more than 5%
of the entire usable area of such facilities, or (c) for whom such facilities or
a part thereof were specifically constructed, reconstructed or acquired.
"Related persons" generally include certain related natural persons, affiliated
corporations, a partnership and its partners and an S corporation and its
shareholders.

     In order for the Funds to pay exempt-interest dividends with respect to any
taxable year, at the close of each quarter of each Fund's taxable year at least
50% of the value of the Fund's assets must consist of tax-exempt municipal
obligations.  Exempt-interest dividends distributed to shareholders are not
included in the shareholder's gross income for regular federal income tax
purposes.  However, all shareholders required to file a federal income tax
return are required to report the receipt of exempt-interest dividends and other
tax-exempt interest on their returns.  Moreover, while such dividends and
interest are exempt from regular federal income tax, they may be subject to
alternative minimum tax in two circumstances.  First, exempt-interest dividends
derived from certain "private activity" bonds issued after August 7, 1986 will
generally constitute an item of tax preference for both corporate and non-
corporate taxpayers.  Second, exempt-interest dividends derived from all bonds,
regardless of the date of issue, must be taken into account by corporate
taxpayers in determining the amount of certain adjustments for alternative
minimum tax purposes.  Receipt of exempt-interest dividends may result in
collateral federal income tax consequences to certain other taxpayers, including
financial institutions, property and casualty insurance companies, individual
recipients of Social Security or Railroad Retirement benefits, and foreign
corporations engaged in a trade or business in the United States.  Prospective
investors should consult their own tax advisors as to such consequences.

     The percentage of total dividends paid by the Fund with respect to any
taxable year which qualifies as federal exempt-interest dividends will be the
same for all shareholders receiving dividends during such year.  If a
shareholder receives an exempt-interest dividend with respect to any share and
such share is held for six months or less, any loss on the sale or exchange of
such share will be disallowed to the extent of the amount of such dividends.

                                       62

     Interest on indebtedness incurred by a shareholder to purchase or carry
shares of the Funds generally is not deductible for federal income tax purposes
if the Funds distribute exempt-interest dividends during the shareholder's
taxable year.

     Investors may be subject to state and local taxes on income derived from an
investment in a Fund.  In certain states, income derived from a Fund which is
attributable to interest on obligations of that state or any municipality or
political subdivision thereof may be exempt from taxation.

     Shareholders are advised to consult their own tax advisers with respect to
the particular tax consequences to them of an investment in a Fund.  Persons who
may be "substantial users" (or "related persons" of substantial users) of
facilities financed by industrial development bonds should consult their tax
advisers before investing in a Fund.

   
     MICHIGAN TAX CONSIDERATIONS - MICHIGAN BOND FUND AND TAX-FREE INTERMEDIATE
BOND FUND.  As stated in the Michigan Bond Fund Prospectus and the Tax-Free
Intermediate Bond Fund Prospectus, dividends paid by the Fund that are derived
from interest attributable to tax-exempt Michigan Municipal Obligations will be
exempt from Michigan Income Tax and Michigan Single Business Tax. Conversely, to
the extent that the Fund's dividends are derived from interest on obligations
other than Michigan Municipal Obligations, such dividends will be subject to
Michigan Income and Michigan Single Business Taxes, even though the dividends
may be exempt for federal Income Tax purposes.       

     In particular, gross interest income and dividends derived from obligations
or securities of the State of Michigan and its political subdivisions, exempt
from federal Income Tax, are exempt from Michigan Income Tax under Act No. 281,
Public Acts of Michigan, 1967, as amended, and are exempt from Michigan Single
Business Tax under Act No. 228, Public Acts of Michigan, 1975, as amended.  The
Michigan Income Tax act levies a flat-rate income tax on individuals, estates,
and trusts.  The Single Business Tax Act levies a tax upon the "adjusted tax
base" of most individuals, corporations, financial organizations, partnerships,
joint ventures, estates, and trusts with "business activity" in Michigan.

         

    
     The transfer of obligations or securities of the State of Michigan and its
political subdivisions by the Fund, as well as the transfer of Fund shares by a
shareholder, is subject to Michigan taxes measured by gain on the sale, payment,
or other disposition thereof.

     INTERNATIONAL EQUITY FUND, INTERNATIONAL GROWTH FUND, EMERGING MARKETS
FUND, GLOBAL FINANCIAL SERVICES FUND AND INTERNATIONAL BOND FUND.  Income
received by the International Equity Fund, the International Growth Fund, the
Emerging Markets Fund, the Global Financial Services Fund and the International
Bond Fund from sources within foreign countries may be subject to withholding
and other foreign taxes.  The payment of such taxes will reduce the amount of
dividends and distributions paid to the Funds' shareholders.  So long as a Fund
qualifies as a regulated investment company, certain distribution requirements
are satisfied, and more than 50% of the value of the Fund's assets at the close
of the taxable year consists of securities of foreign corporations, the Fund may
elect, subject to limitation, to pass through its foreign tax credits to its
shareholders.  The Fund may qualify for and make this election in some, but not
necessarily all, of its taxable years.  If a Fund were to make an election, an
amount equal to the foreign income taxes paid by the Fund would be included in
the income of its shareholders and the shareholders would be entitled to credit
their portions of this amount against their U.S. tax due, if any, or to deduct
such portions from their U.S. taxable income, if any.  Shortly after any year
for which it makes such an election, a Fund will report to its shareholders, in
writing, the amount per share of such foreign tax that must be included in each
shareholder's gross income and the amount which will be available for deduction
or credit.  No      

                                       63
<PAGE>

    
deduction for foreign taxes may be claimed by a shareholder who does not itemize
deductions. Certain limitations are imposed on the extent to which the credit
(but not the deduction) for foreign taxes may be claimed.      

     Shareholders who choose to utilize a credit (rather than a deduction) for
foreign taxes will be subject to limitations, including the restriction that the
credit may not exceed the shareholder's United States tax (determined without
regard to the availability of the credit) attributable to his or her total
foreign source taxable income.  For this purpose, the portion of dividends and
distributions paid by the Fund from its foreign source income will be treated as
foreign source income.  The Fund's gains and losses from the sale of securities
will generally be treated as derived from United States sources and certain
foreign currency gains and losses likewise will be treated as derived from
United States sources.  The limitation on the foreign tax credit is applied
separately to foreign source "passive income", such as the portion of dividends
received from the Fund which qualifies as foreign source income.  In addition,
only a portion of the foreign tax credit will be allowed to offset any
alternative minimum tax imposed on corporations and individuals.  Because of
these limitations, shareholders may be unable to claim a credit for the full
amount of their proportionate shares of the foreign income taxes paid by the
Fund.

     TAXATION OF CERTAIN FINANCIAL INSTRUMENTS.  Special rules govern the
Federal income tax treatment of financial instruments that may be held by some
of the Funds.  These rules may have a particular impact on the amount of income
or gain that the Funds must distribute to their respective shareholders to
comply with the Distribution Requirement, on the income or gain qualifying under
the Income Requirement, all described above.

     MARKET DISCOUNT.  If a Fund purchases a debt security at a price lower than
the stated redemption price of such debt security, the excess of the stated
redemption price over the purchase price is "market discount".  If the amount of
market discount is more than a de minimis amount, a portion of such market
discount must be included as ordinary income (not capital gain) by the Fund in
each taxable year in which the Fund owns an interest in such debt security and
receives a principal payment on it.  In particular, the Fund will be required to
allocate that principal payment first to the portion of the market discount on
the debt security that has accrued but has not previously been includable in
income.  In general, the amount of market discount that must be included for
each period is equal to the lesser of (i) the amount of market discount accruing
during such period (plus any accrued market discount for prior periods not
previously taken into account) or (ii) the amount of the principal payment with
respect to such period.  Generally, market discount accrues on a daily basis for
each day the debt security is held by a Fund at a constant rate over the time
remaining to the debt security's maturity or, at the election of the Fund, at a
constant yield to maturity which takes into account the semi-annual compounding
of interest.  Gain realized on the disposition of a market discount obligations
must be recognized as ordinary interest income (not capital gain) to the extent
of the "accrued market discount."

     ORIGINAL ISSUE DISCOUNT.  Certain debt securities acquired by the Funds may
be treated as debt securities that were originally issued at a discount.  Very
generally, original issue discount is defined as the difference between the
price at which a security was issued and its stated redemption price at
maturity.  Although no cash income on account of such discount is actually
received by a Fund, original issue discount that accrues on a debt security in a
given year generally is treated for federal income tax purposes as interest and,
therefore, such income would be subject to the distribution requirements
applicable to regulated investment companies.

     Some debt securities may be purchased by the Fund, at a discount that
exceeds the original issue discount on such debt securities, if any.  This
additional discount represents market discount for federal income tax purposes
(see above).

     HEDGING TRANSACTIONS.  The taxation of equity options and over-the-counter
options on debt securities is governed by Code section 1234.  Pursuant to Code
section 1234, the premium received by a Fund for selling a put or call option is
not included in income at the time of receipt.  If the option expires, the
premium is short-term capital gain to the Fund.  If the Fund enters into a
closing transaction, the difference between the amount paid to close out its
position and the premium received is short-term capital gain or loss.  If a call
option written by a Fund is exercised, thereby requiring the Fund to sell the
underlying security, the premium will increase the amount realized upon the sale
of such security and any resulting gain or loss will be a capital gain or loss,
and will be long-term or short-term depending upon the holding period of the
security.  With respect to a put or call option that is 

                                       64
<PAGE>
 
purchased by a Fund, if the option is sold, any resulting gain or loss will be a
capital gain or loss, and will be long-term or short-term, depending upon the
holding period of the option. If the option expires, the resulting loss is a
capital loss and is long-term or short-term, depending upon the holding period
of the option. If the option is exercised, the cost of the option, in the case
of a call option, is added to the basis of the purchased security and, in the
case of a put option, reduces the amount realized on the underlying security in
determining gain or loss.

     Any regulated futures and foreign currency contracts and certain options
(namely, nonequity options and dealer equity options) in which a Fund may invest
may be "section 1256 contracts." Gains or losses on section 1256 contracts are
generally considered 60% long-term and 40% short-term capital gains or losses;
however, foreign currency gains or losses arising from certain section 1256
contracts may be treated as ordinary income or loss.  Also, section, 1256
contracts held by a Fund at the end of each taxable year (and generally for
purposes of the 4% excise tax, on October 31 of each year) are "marked-to-
market" with the result that unrealized gains or losses are treated as though
they were realized.

     Generally, hedging transactions, if any, undertaken by a Fund may result in
"straddles" for U.S. federal income tax purposes.  The straddle rules may affect
the character of gains (or losses) realized by the Funds.  In addition, losses
realized by a Fund on positions that are part of a straddle may be deferred
under the straddle rules, rather than being taken into account in calculating
the taxable income for the taxable year in which such losses are realized.
Because only a few regulations implementing the straddle rules have been
promulgated, the tax consequences of hedging transactions to the Funds are not
entirely clear.  The hedging transactions may increase the amount of short-term
capital gain realized by the Funds which is taxed as ordinary income when
distributed to shareholders.

     The Funds may make one or more of the elections available under the Code
which are applicable to straddles.  If a Fund makes any of the elections, the
amount, character and timing of the recognition of gains or losses from the
affected straddle positions will be determined under rules that vary according
to the election(s) made.  The rules applicable under certain of the elections
may operate to accelerate the recognition of gains or losses from the affected
straddle positions.

     Because application of the straddle rules may affect the character of gains
or losses, defer losses and/or accelerate the recognition of gains or losses
from the affected straddle positions, the amount which must be distributed to
shareholders, and which will be taxed to shareholders as ordinary income or
long-term capital gain, may be increased or decreased substantially as compared
to a fund that did not engage in such hedging transactions.

     The diversification requirements applicable to the Funds' assets may limit
the extent to which the Funds will be able to engage in transactions in options,
futures or forward contracts.

     CONSTRUCTIVE SALES.  Recently enacted rules may affect the timing and
character of gain if a Fund engages in transactions that reduce or eliminate its
risk of loss with respect to appreciated financial positions.  If the Fund
enters into certain transactions in property while holding substantially
identical property, the Fund would be treated as if it had sold and immediately
repurchased the property and would be taxed on any gain (but not loss) from the
constructive sale.  The character of gain from a constructive sale would depend
upon the Fund's holding period in the property.  Loss from a constructive sale
would be recognized when the property was subsequently disposed of, and its
character would depend on the Fund's holding period and the application of
various loss deferral provisions of the Code.

     CURRENCY FLUCTUATIONS - "Section 988" Gains or Losses.  Under the Code,
gains or losses attributable to fluctuations in exchange rates which occur
between the time a Fund accrues receivables or liabilities denominated in a
foreign currency and the time the Fund actually collects such receivables or
pays such liabilities generally are treated as ordinary income and loss.
Similarly, on disposition of debt securities denominated in a foreign currency
and on disposition of certain futures, forward contracts and options, gains or
losses attributable to fluctuations in the value of the foreign currency between
the date of acquisition of the security or contract and the date of disposition
also are treated as ordinary gain or loss.  These gains or losses, referred to
under the Code as "Section 988" gains or 

                                       65
<PAGE>
 
losses, may increase or decrease the amount of a Fund's investment company
taxable income to be distributed to its shareholders as ordinary income.

     PASSIVE FOREIGN INVESTMENT COMPANIES.  Certain Funds may invest in shares
of foreign corporations that may be classified under the Code as passive foreign
investment companies ("PFICs").  In general, a foreign corporation is classified
as a PFIC if at least on-half of its assets constitute investment-type assets,
or 75% or more of its gross income investment-type income.  If a Fund receives a
so-called "excess distribution" with respect to PFIC stock, the Fund itself may
be subject to a tax on a portion of the excess distribution, whether or not the
corresponding income is distributed by the Fund to shareholders.  In general,
under the PFIC rules, an excess distribution is treated as having been realized
ratably over the period during which the Fund held the PFIC shares.  Each Fund
will itself be subject to tax on the portion, if any, of an excess distribution
that is so allocated to prior Fund taxable years and an interest factor will be
added to the tax, as if the tax had been payable in such prior taxable years.
Certain distributions from a PFIC as well as gain from the sale of PFIC shares
are treated as excess distributions.  Excess distributions are characterized as
ordinary income even though, absent application of the PFIC rules, certain
excess distributions might have been classified as capital gain.

     The Funds may be eligible to elect alternative tax treatment with respect
to PFIC shares.  Under an election that currently is available in some
circumstances, a Fund generally would be required to include in its gross income
its share of the earnings of a PFIC on a current basis, regardless of whether
distributions were received from the PFIC in a given year.  If this election
were made, the special rules, discussed above, relating to the taxation of
excess distributions, would not apply.  In addition, another election would
involve marking to market the Fund's PFIC shares at the end of each taxable
year, with the result that unrealized gains would be treated as though they were
realized and reported as ordinary income.  Any mark-to market losses and any
loss from an actual disposition of Fund shares would be deductible as ordinary
losses to the extent of any net mark-to-market gains included in income in prior
years.

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

     Fund shareholders may be subject to state, local and foreign taxes on their
Fund distributions.  In many states, Fund distributions which are derived from
interest on certain U.S. Government obligations are exempt from taxation.  The
tax consequences to a foreign shareholder of an investment in the Fund may be
different from those described herein.  Foreign shareholders are advised to
consult their own tax advisers with respect to the particular tax consequences
to them of an investment in the Fund.  Shareholders are advised to consult their
own tax advisers with respect to the particular tax consequences to them of an
investment in the Fund.

OTHER TAXATION

     The foregoing discussion relates only to U.S. federal income tax law and
certain state taxes as applicable to U.S. persons (i.e., U.S. citizens and
residents and domestic corporations, partnerships, trusts and estates).
Distributions by the Funds, and dispositions of Fund shares also may be subject
to other state and local taxes, and their treatment under state and local income
tax laws may differ from the U.S. federal income tax treatment.  Shareholders
should consult their tax advisers with respect to particular questions of U.S.
federal, state and local taxation.  Shareholders who are not U.S. persons should
consult their tax advisers regarding U.S. and foreign tax consequences of
ownership of shares of the Fund, including the likelihood that distributions to
them would be subject to withholding of U.S. federal income tax at a rate of 30%
(or at a lower rate under a tax treaty).  Future legislative or administrative
changes or court decisions may significantly change the conclusions expressed
herein, and any such changes or decisions may have a retroactive effect with
respect to the transactions contemplated herein.

                    ADDITIONAL INFORMATION CONCERNING SHARES

     The Trust and Framlington are Massachusetts business trusts.  Under each
Declaration of Trust, the beneficial interest in the Trust or Framlington may be
divided into an unlimited number of full and fractional 

                                       66
<PAGE>

     
transferable shares.  The Company is a Maryland corporation.  The Trust's and
Framlington's Declaration of Trust and the Company's Articles of Incorporation
authorize the Boards of Directors/Trustees to classify or reclassify any
unissued shares of the Trust, Framlington and the Company into one or more
classes by setting or changing, in any one or more respects, their respective
designations, preferences, conversion or other rights, voting powers,
restrictions, limitations, qualifications and terms and conditions of
redemption.  Pursuant to such authority, the Trust's Board of Trustees has
authorized the issuance of an unlimited number of shares of beneficial interest
in the Trust, representing interests in the Balanced, Growth & Income, Index
500, International Equity, Small Company Growth, Bond, Intermediate Bond, U.S.
Income, Michigan Bond, Tax-Free Bond, Tax-Free Intermediate Bond, Cash
Investment, Tax-Free Money Market and U.S. Treasury Money Market Funds.  The
shares of each Fund (other than the Cash Investment Fund, Tax-Free Money Market
Fund and U.S. Treasury Money Market Fund) are offered in five separate classes:
Class A, Class B, Class C, Class K and Class Y Shares.  The Cash Investment
Fund, Tax-Free Money Market Fund and U.S. Treasury Money Market Fund offer only
Class A Shares, Class K Shares and Class Y Shares.  Pursuant to the authority of
Framlington's Declaration of Trust, the Trustees have authorized the issuance of
an unlimited number of shares of beneficial interest in Framlington representing
interests in the International Growth Fund, Emerging Markets Fund, Global
Financial Services Fund and Healthcare Fund.  The shares of each Fund are
offered in five separate classes: Class A, Class B, Class C, Class K and Class Y
Shares. Pursuant to the authority of the Company's Articles of Incorporation,
the Directors have authorized the issuance of shares of common stock
representing interests in the Equity Selection Fund, Growth Opportunities Fund,
Micro-Cap Fund, Multi-Season Fund, Real Estate Fund, Small-Cap Value Fund, Value
Fund, International Bond Fund, Money Market Fund, All-Season Conservative Fund,
All-Season Moderate Fund, All-Season Aggressive Fund, Financial Services Fund,
Short Term Treasury Fund and NetNet Fund.  The shares of each Fund (other than
the Money Market Fund, All-Season Conservative Fund, All-Season Moderate Fund,
All-Season Aggressive Fund, Financial Services Fund, Short Term Treasury Fund
and the NetNet Fund) are offered in five separate classes: Class A, Class B,
Class C, Class K and Class Y Shares.  The Money Market Fund offers only Class A,
Class B and Class C Shares (which may be acquired only through an exchange of
shares from the corresponding classes of other funds of the Trust, Framlington
and the Company) and Class Y Shares.  The All-Season Conservative Fund, All-
Season Moderate Fund and All-Season Aggressive Fund offer only Class A, Class B
and Class Y Shares.  The Short Term Treasury Fund offers Class Y Shares and the
Michigan Municipal Shares (formerly, Class K Shares).  The NetNet Fund offers
only Class A, Class B, Class C and Class Y Shares.

     The Boards of the Trust, the Company and Framlington have adopted plans
pursuant to Rule 18f-3 under the 1940 Act ("Multi-Class Plans") on behalf of
each Fund.  Each Multi-Class Plan provides that shares of each class of a Fund
are identical, except for one or more expense variables, certain related rights,
exchange privileges, class designation and sales loads assessed due to differing
distribution methods.

     In the event of a liquidation or dissolution of the Trust, Framlington or
the Company or an individual Fund, shareholders of a particular Fund would be
entitled to receive the assets available for distribution belonging to such
Fund, and a proportionate distribution, based upon the relative net asset values
of the Trust's, Framlington's or the Company's respective Funds, of any general
assets not belonging to any particular Fund which are available for
distribution.  Shareholders of a Fund are entitled to participate in the net
distributable assets of the particular Fund involved on liquidation, based on
the number of shares of the Fund that are held by each shareholder.

     Holders of all outstanding shares of a particular Fund will vote together
in the aggregate and not by class on all matters, except that only Class A
Shares of a Fund will be entitled to vote on matters submitted to a vote of
shareholders pertaining to the Fund's Class A Plan, only Class B Shares will be
entitled to vote on matters submitted to a vote of shareholders pertaining to
the Fund's Class B Plan, only Class C Shares of a Fund will be entitled to vote
on matters submitted to a vote of shareholders pertaining to the Fund's Class C
Plan, and only Class K Shares of a Fund will be entitled to vote on matters
submitted to a vote of shareholders pertaining to the Class K Plan.  Further,
shareholders of all of the Funds, as well as those of any other investment
portfolio now or hereafter offered by the Trust, Framlington or the Company,
will vote together in the aggregate and not separately on a Fund-by-Fund basis,
except as otherwise required by law or when permitted by the Boards of
Directors/Trustees.  Rule 18f-2 under the 1940 Act provides that any matter
required to be submitted to the holders of the outstanding voting securities of
an investment company such as the Trust, Framlington or the Company shall not be
deemed to have been effectively acted upon unless approved by the holders of a
majority of the outstanding shares of each Fund      

                                       67
<PAGE>

     
affected by the matter. A Fund is affected by a matter, (i) unless it is clear
that the interests of each Fund in the matter are substantially identical or
(ii) that the matter does not affect any interest of the Fund. Under the Rule,
the approval of an investment advisory agreement, sub-advisory agreement or any
change in a fundamental investment policy would be effectively acted upon with
respect to a Fund only if approved by a majority of the outstanding shares of
such Fund. However, the Rule also provides that the ratification of the
appointment of independent auditors, the approval of principal underwriting
contracts and the election of trustees may be effectively acted upon by
shareholders of the Trust, Framlington or the Company voting together in the
aggregate without regard to a particular Fund.      

     Shares of each of the Trust, Framlington and the Company have noncumulative
voting rights and, accordingly, the holders of more than 50% of each of the
Trust's, Framlington's and the Company's outstanding shares (irrespective of
class) may elect all of the trustees or directors.  Shares have no preemptive
rights and only such conversion and exchange rights as the Board may grant in
its discretion.  When issued for payment as described in the applicable
Prospectus, shares will be fully paid and non-assessable by each of the Trust,
Framlington and the Company.
    
     Annual shareholder meetings to elect trustees or directors will not be held
unless and until such time as required by law.  At that time, the trustees then
in office will call a shareholders' meeting to elect trustees.  Except as set
forth above, the trustees will continue to hold office and may appoint successor
trustees.  Meetings of the shareholders of the Trust, Framlington or the Company
shall be called by the trustees or directors upon the written request of
shareholders owning at least 10% of the outstanding shares entitled to vote.

     The Trust's and Framlington's Declaration of Trust, as amended, each
authorizes the Board of Trustees, without shareholder approval (unless otherwise
required by applicable law), to: (i) sell and convey the assets belonging to a
class of shares to another management investment company for consideration which
may include securities issued by the purchaser and, in connection therewith, to
cause all outstanding shares of such class to be redeemed at a price which is
equal to their net asset value and which may be paid in cash or by distribution
of the securities or other consideration received from the sale and conveyance;
(ii) sell and convert the assets belonging to one or more classes of shares into
money and, in connection therewith, to cause all outstanding shares of such
class to be redeemed at their net asset value; or (iii) combine the assets
belonging to a class of shares with the assets belonging to one or more other
classes of shares if the Board of Trustees reasonably determines that such
combination will not have a material adverse effect on the shareholders of any
class participating in such combination and, in connection therewith, to cause
all outstanding shares of any such class to be redeemed or converted into shares
of another class of shares at their net asset value.  However, the exercise of
such authority may be subject to certain restrictions under the 1940 Act.  The
Trust's and Framlington's Board of Trustees may authorize the termination of any
class of shares after the assets belonging to such class have been distributed
to its shareholders.      

                                 MISCELLANEOUS

Washington, DC 20006, has passed upon certain legal matters in connection with
the shares offered by the Funds and serves as counsel to the Trust, Framlington
and the Company.

     Excerpts from Moody's Investors Services, Inc. ("Moody's") description of
its bond ratings:

     "Aaa":
          Bonds that 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 edge." 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 that 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.

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

     "Baa":
          Bonds that are rated "Baa" are considered as medium grade obligations,
       i.e., they are neither highly protected nor poorly secured.  Interest
       payments and principal security appears 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 that 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 that are rated "B" generally lack characteristics of desirable
       investments.  Assurance of interest and principal payments or of
       maintenance of other terms of the contract over any long period of time
       may be small.

     "Caa":
          Bonds that are rated "Caa" are of poor standing.  These issues may be
       in default or present elements of danger may exist with respect to
       principal or interest.

     Moody's applies numerical modifiers (1, 2 and 3) with respect to bonds
rated "Aa" through "B".  The modifier 1 indicates that the bond being rated
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 bond ranks in the
lower end of its generic rating category.

     Excerpts from Standard & Poor's Corporation ("S&P") description of its 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 "AAA" issues by a 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":
          Bonds rated "BBB" are regarded as having an adequate capacity to pay
       interest and repay principal.  Whereas they normally exhibit 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 bonds in this category than for bonds in
       higher rated categories.

     "BB", "B" and "CCC":
          Bonds rated "BB" and "B" are regarded, on balance, as predominantly
       speculative with respect to capacity to pay interest and repay principal
       in accordance with the terms of the obligations.  "BB" represents a lower
       degree of speculation than "B" and "CCC" the highest degree of
       speculation.  While such bonds will likely have some quality and
       protective characteristics, these are outweighed by large uncertainties
       or major risk exposures to adverse conditions.

     To provide more detailed indications of credit quality, the "AA" or "A"
ratings may be modified by the addition of a plus or minus sign to show relative
standing within these major rating categories.

Commercial Paper
- ----------------

     The rating "Prime-1" is the highest commercial paper rating assigned by
Moody's.  These issues (or related supporting institutions) are considered to
have a superior capacity for repayment of short-term promissory obligations.
Issues rated "Prime-2" (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations.  This will normally
be evidenced by many of the characteristics of "Prime-1" rated issues, but to a
lesser degree.  Earnings trends and coverage ratios, while sound, will be more
subject to variation.  Capitalization characteristics, while still appropriate,
may be more affected by external conditions.  Ample alternate liquidity is
maintained.

     Commercial paper ratings of S&P are current assessments of the likelihood
of timely payment of debt having original maturities of no more than 365 days.
Commercial paper rated "A-1" by S&P indicates that the degree of safety
regarding timely payment is either overwhelming or very strong.  Those issues
determined to possess overwhelming safety characteristics are denoted "A-1+."
Commercial paper rated "A-2" by S&P indicates that capacity for timely payment
is strong.  However, the relative degree of safety is not as high as for issues
designated "A-1."

     Rated commercial paper purchased by a Fund must have (at the time of
purchase) the highest quality rating assigned to short-term debt securities or,
if not rated, or rated by only one agency, are determined to be of comparative
quality pursuant to guidelines approved by a Fund's Boards of Trustees and
Directors.  Highest quality ratings for commercial paper for Moody's and S&P are
as follows:

     Moody's: The rating "Prime-1" is the highest commercial paper rating
category assigned by Moody's.  These issues (or related supporting institutions)
are considered to have a superior capacity for repayment of short-term
promissory obligations.

     S&P: Commercial paper ratings of S&P are current assessments of the
likelihood of timely payment of debts having original maturities of no more than
365 days.  Commercial paper rated in the "A-1" category by S&P indicates that
the degree of safety regarding timely payment is either overwhelming or very
strong.  Those issues determined to possess overwhelming safety characteristics
are denoted "A-1+".

     As stated in the applicable Prospectuses, the Equity Funds, the Balanced
Fund and the Bond Funds may enter into certain futures transactions and options
for hedging purposes.  Such transactions are described in this Appendix.

I. Interest Rate Futures Contracts
   -------------------------------

     Use of Interest Rate Futures Contracts.  Bond prices are established in
both the cash market and the futures market.  In the cash market, bonds are
purchased and sold with payment for the full purchase price of the bond being
made in cash, generally within five business days after the trade.  In the
futures market, only a contract is made to purchase or sell a bond in the future
for a set price on a certain date.  Historically, the prices for bonds
established in the futures markets have tended to move generally in the
aggregate in concert with the cash market prices and have maintained fairly
predictable relationships.  Accordingly, the Funds may use interest rate futures
contracts as a defense, or hedge, against anticipated interest rate changes and
not for speculation.  As described below, this would include the use of futures
contract sales to protect against expected increases in interest rates and
futures contract purchases to offset the impact of interest rate declines.

     The Funds presently could accomplish a similar result to that which it
hopes to achieve through the use of futures contracts by selling bonds with long
maturities and investing in bonds with short maturities when interest rates are
expected to increase, or conversely, selling short-term bonds and investing in
long-term bonds when interest rates are expected to decline.  However, because
of the liquidity that is often available in the futures market, the protection
is more likely to be achieved, perhaps at a lower cost and without changing the
rate of interest being earned by the Funds, through using futures contracts.

     Description of Interest Rate Futures Contracts.  An interest rate futures
contract sale would create an obligation by a Fund, as seller, to deliver the
specific type of financial instrument called for in the contract at a specific
future time for a specified price.  A futures contract purchase would create an
obligation by the Fund, as purchaser, to take delivery of the specific type of
financial instrument at a specific future time at a specific price.  The
specific securities delivered or taken, respectively, at settlement date, would
not be determined until or at near that date.  The determination would be in
accordance with the rules of the exchange on which the futures contract sale or
purchase was made.

     Although interest rate futures contracts by their terms call for actual
delivery or acceptance of securities, in most cases the contracts are closed out
before the settlement date without making or taking of delivery of securities.
Closing out a futures contract sale is effected by the Fund's entering into a
futures contract purchase for the same aggregate amount of the specific type of
financial instrument and the same delivery date.  If the price of the sale
exceeds the price of the offsetting purchase, the Fund is immediately paid the
difference and thus realizes a gain.  If the offsetting purchase price exceeds
the sale price, the Fund pays the difference and realizes a loss.  Similarly,
the closing out of a futures contract purchase is effected by the Fund entering
into a futures contract sale.  If the offsetting sale price exceeds the purchase
price, the Fund realizes a gain, and if the purchase price exceeds the
offsetting sale price, the Fund realizes a loss.

     Interest rate futures contracts are traded in an auction environment on the
floors of several exchanges - principally, the Chicago Board of Trade, the
Chicago Mercantile Exchange and the New York Futures Exchange.  The Funds would
deal only in standardized contracts on recognized exchanges.  Each exchange
guarantees performance under contract provisions through a clearing corporation,
a nonprofit organization managed by the exchange membership.

     A public market now exists in futures contracts covering various financial
instruments including long-term United States Treasury Bonds and Notes,
Government National Mortgage Association (GNMA) modified pass-through mortgage
backed securities, three-month United States Treasury Bills, and ninety-day
commercial paper.  

                                      B-1
<PAGE>
 
The Funds may trade in any interest rate futures contracts for which there
exists a public market, including, without limitation, the foregoing
instruments.

     Example of Futures Contract Sale.  The Funds would engage in an interest
rate futures contract sale to maintain the income advantage from continued
holding of a long-term bond while endeavoring to avoid part or all of the loss
in market value that would otherwise accompany a decline in long-term securities
prices.  Assume that the market value of a certain security held by a particular
Fund tends to move in concert with the futures market prices of long-term United
States Treasury bonds ("Treasury Bonds").  The adviser wishes to fix the current
market value of the portfolio security until some point in the future.  Assume
the portfolio security has a market value of 100, and the adviser believes that,
because of an anticipated rise in interest rates, the value will decline to 95.
The fund might enter into futures contract sales of Treasury bonds for an
equivalent of 98.  If the market value of the portfolio security does indeed
decline from 100 to 95, the equivalent futures market price for the Treasury
bonds might also decline from 98 to 93.

     In that case, the five point loss in the market value of the portfolio
security would be offset by the five point gain realized by closing out the
futures contract sale.  Of course, the futures market price of Treasury bonds
might well decline to more than 93 or to less than 93 because of the imperfect
correlation between cash and futures prices mentioned below.
    
     The advisor could be wrong in its forecast of interest rates and the
equivalent futures market price could rise above 98.  In this case, the market
value of the portfolio securities, including the portfolio security being
protected, would increase.  The benefit of this increase would be reduced by the
loss realized on closing out the futures contract sale.      

     If interest rate levels did not change, the Fund in the above example might
incur a loss of 2 points (which might be reduced by an offsetting transaction
prior to the settlement date).  In each transaction, transaction expenses would
also be incurred.

     Example of Futures Contract Purchase.  The Funds would engage in an
interest rate futures contract purchase when they are not fully invested in
long-term bonds but wish to defer for a time the purchase of long-term bonds in
light of the availability of advantageous interim investments, e.g., shorter
term securities whose yields are greater than those available on long-term
bonds.  A Fund's basic motivation would be to maintain for a time the income
advantage from investing in the short-term securities; the Fund would be
endeavoring at the same time to eliminate the effect of all or part of an
expected increase in market price of the long-term bonds that the Fund may
purchase.
    
     For example, assume that the market price of a long-term bond that the Fund
may purchase, currently yielding 10%, tends to move in concert with futures
market prices of Treasury bonds.  The advisor wishes to fix the current market
price (and thus 10% yield) of the long-term bond until the time (four months
away in this example) when it may purchase the bond.  Assume the long-term bond
has a market price of 100, and the advisor believes that, because of an
anticipated fall in interest rates, the price will have risen to 105 (and the
yield will have dropped to about 9 1/2%) in four months.  The Fund might enter
into futures contracts purchases of Treasury bonds for an equivalent price of
98.  At the same time, the Fund would assign a pool of investments in short-term
securities that are either maturing in four months or earmarked on the books of
the Fund or the Fund's sub-custodian for sale in four months, for purchase of
the long-term bond at an assumed market price of 100.  Assume these short-term
securities are yielding 15%.  If the market price of the long-term bond does
indeed rise from 100 to 105, the equivalent futures market price for Treasury
bonds might also rise from 98 to 103.  In that case, the 5 point increase in the
price that the Fund pays for the long-term bond would be offset by the 5 point
gain realized by closing out the futures contract purchase.

     The advisor could be wrong in its forecast of interest rates; long-term
interest rates might rise to above 10%; and the equivalent futures market price
could fall below 98.  If short-term rates at the same time fall to 10% or below,
it is possible that the Fund would continue with its purchase program for long-
term bonds.  The market price      

                                      B-2

of available long-term bonds would have decreased. The benefit of this price
decrease, and thus yield increase, will be reduced by the loss realized on
closing out the futures contract purchase.      

     If, however, short-term rates remained above available long-term rated, it
is possible that the Fund would discontinue its purchase program for long-term
bonds.  The yield on short-term securities in the portfolio, including those
originally in the pool assigned to the particular long-term bond, would remain
higher than yields on long-term bonds.  The benefit of this continued
incremental income will be reduced by the loss realized on closing out the
futures contract purchase.  In each transaction, expenses would also be
incurred.

II. Index Futures Contracts
    -----------------------

     General.  A bond index assigns relative values of the bonds included in the
index and the index fluctuates with changes in the market values of the bonds
included.  The Chicago Board of Trade has designed a futures contract based on
the Bond Buyer Municipal Bond Index.  This Index is composed of 40 term revenue
and general obligation bonds and its composition is updated regularly as new
bonds meeting the criteria of the Index are issued and existing bonds mature.
The Index is intended to provide an accurate indicator of trends and changes in
the municipal bond market.  Each bond in the Index is independently priced by
six dealer-to-dealer municipal bond brokers daily.  The 40 prices then are
averaged and multiplied by a coefficient.  The coefficient is used to maintain
the continuity of the Index when its composition changes.

     A stock index assigns relative values to the stocks included in the index
and the index fluctuates with changes in the market values of the stocks
included.  Some stock index futures contracts are based on broad market indices,
such as the Standard & Poor's 500 or the New York Stock Exchange Composite
Index.  In contrast, certain exchanges offer futures contracts on narrower
market indices, such as the Standard & Poor's 100 or indices based on an
industry or market segment, such as oil and gas stocks.

     Futures contracts are traded on organized exchanges regulated by the
Commodity Futures Trading Commission.  Transactions on such exchanges are
cleared through a clearing corporation, which guarantees the performance of the
parties to each contract.

     A Fund will sell index futures contracts in order to offset a decrease in
market value of its portfolio securities that might otherwise result from a
market decline.  A Fund will purchase index futures contracts in anticipation of
purchases of securities.  In a substantial majority of these transactions, a
Fund will purchase such securities upon termination of the long futures
position, but a long futures position may be terminated without a corresponding
purchase of securities.

     In addition, a Fund may utilize index futures contracts in anticipation of
changes in the composition of its portfolio holdings.  For example, in the event
that a Fund expects to narrow the range of industry groups represented in its
holdings it may, prior to making purchases of the actual securities, establish a
long futures position based on a more restricted index, such as an index
comprised of securities of a particular industry group.  A Fund may also sell
futures contracts in connection with this strategy, in order to protect against
the possibility that the value of the securities to be sold as part of the
restructuring of the portfolio will decline prior to the time of sale.

     Examples of Stock Index Futures Transactions.  The following are examples
of transactions in stock index futures (net of commissions and premiums, if
any).

</TABLE> 

III. Margin Payments
     ---------------
    
     Unlike purchase or sales of portfolio securities, no price is paid or
received by a Fund upon the purchase or sale of a futures contract.  Initially,
the Fund will be required to deposit with the broker or in a segregated account
with the Fund's sub-custodian in an amount of cash or cash equivalents, known as
initial margin, based on the value of the contract.  The nature of initial
margin in futures transactions is different from that of margin in security
transactions in that futures contract margin does not involve the borrowing of
funds by the customer to finance the transactions.  Rather, the initial margin
is in the nature of a performance bond or good faith deposit on the contract
which is returned to the Fund upon termination of the futures contract assuming
all contractual obligations have been satisfied.  Subsequent payments, called
variation margin, to and from the broker, will be made on a daily basis as the
price of the underlying instruments fluctuates making the long and short
positions in the futures contract more or less valuable, a process known as
marking-to-the-market.  For example, when a particular Fund has purchased a
futures contract and the price of the contract has risen in response to a rise
in the underlying instruments, that position will have increased in value and
the Fund will be entitled to receive from the broker a variation margin payment
equal to that increase in value.  Conversely, where the Fund has purchased a
futures contract and the price of the futures contract has declined in response
to a decrease in the underlying instruments, the position would be less valuable
and the Fund would be required to make a variation margin payment to the broker.
At any time prior to expiration of the futures contract, the Advisor or Sub-
Advisor may elect to close the position by taking an opposite position, subject
to the availability of a secondary market, which will operate to terminate the
Fund's position in the futures contract.  A final determination of variation
margin is then made, additional cash is required to be paid by or released to
the Fund, and the Fund realizes a loss or gain.      

IV. Risks of Transactions in Futures Contracts
    ------------------------------------------

     There are several risks in connection with the use of futures by the Funds
as hedging devices.  One risk arises because of the imperfect correlation
between movements in the price of the futures and movements in the price of the
instruments which are the subject of the hedge.  The price of the future may
move more than or less than the price of the instruments being hedged.  If the
price of the futures moves less than the price of the instruments which are the
subject of the hedge, the hedge will not be fully effective but, if the price of
the instruments being hedged has moved in an unfavorable direction, the Fund
would be in a better position than if it 

                                      B-4
<PAGE>

     
had not hedged at all. If the price of the instruments being hedged has moved in
a favorable direction, this advantage will be partially offset by the loss on
the futures. If the price of the futures moves more than the price of the hedged
instruments, the Fund involved will experience either a loss or gain on the
futures which will not be completely offset by movements in the price of the
instruments which are the subject of the hedge. To compensate for the imperfect
correlation of movements in the price of instruments being hedged and movements
in the price of futures contracts, the Fund may buy or sell futures contracts in
a greater dollar amount than the dollar amount of instruments being hedged if
the volatility over a particular time period of the prices of such instruments
has been greater than the volatility over such time period of the futures, or if
otherwise deemed to be appropriate by the Advisor or Sub-Advisor. Conversely,
the Funds may buy or sell fewer futures contracts if the volatility over a
particular time period of the prices of the instruments being hedged is less
than the volatility over such time period of the futures contract being used, or
if otherwise deemed to be appropriate by the Advisor or Sub-Advisor. It is also
possible that, when the Fund had sold futures to hedge its portfolio against a
decline in the market, the market may advance and the value of instruments held
in the Fund may decline. If this occurred, the Fund would lose money on the
futures and also experience a decline in value in its portfolio securities.     

     Where futures are purchased to hedge against a possible increase in the
price of securities before a Fund is able to invest its cash (or cash
equivalents) in an orderly fashion, it is possible that the market may decline
instead; if the Fund then concludes not to invest its cash at that time because
of concern as to possible further market decline or for other reasons, the Funds
will realize a loss on the futures contract that is not offset by a reduction in
the price of the instruments that were to be purchased.
    
     In instances involving the purchase of futures contracts by the Funds, an
amount of cash and cash equivalents, equal to the market value of the futures
contracts, will be deposited in a segregated account with the Fund's sub-
custodian and/or in a margin account with a broker to collateralize the position
and thereby insure that the use of such futures is unleveraged.

     In addition to the possibility that there may be an imperfect correlation,
or no correlation at all, between movements in the futures and the instruments
being hedged, the price of futures may not correlate perfectly with movement in
the cash market due to certain market distortions.  Rather than meeting
additional margin deposit requirements, investors may close futures contracts
through off-setting transactions which could distort the normal relationship
between the cash and futures markets.  Second, with respect to financial futures
contracts, the liquidity of the futures market depends on participants entering
into off-setting transactions rather than making or taking delivery.  To the
extent participants decide to make or take delivery, liquidity in the futures
market could be reduced thus producing distortions.  Third, from the point of
view of speculators, the deposit requirements in the futures market are less
onerous than margin requirements in the securities market.  Therefore, increased
participation by speculators in the futures market may also cause temporary
price distortions.  Due to the possibility of price distortion in the futures
market, and because of the imperfect correlation between the movements in the
cash market and movements in the price of futures, a correct forecast of general
market trends or interest rate movements by the Advisor or Sub-Advisor may still
not result in a successful hedging transaction over a short time frame.      

     Positions in futures may be closed out only on an exchange or board of
trade which provides a secondary market for such futures.  Although the Funds
intend to purchase or sell futures only on exchanges or boards of trade where
there appear to be active secondary markets, there is no assurance that a liquid
secondary market on any exchange or board of trade will exist for any particular
contract or at any particular time.  In such event, it may not be possible to
close a futures investment position, and in the event of adverse price
movements, the Funds would continue to be required to make daily cash payments
of variation margin.  However, in the event futures contracts have been used to
hedge portfolio securities, such securities will not be sold until the futures
contract can be terminated.  In such circumstances, an increase in the price of
the securities, if any, may partially or completely offset losses on the futures
contract.  However, as described above, there is no guarantee that the price of
the securities will in fact correlate with the price movements in the futures
contract and thus provide an offset on a futures contract.

     Further, it should be noted that the liquidity of a secondary market in a
futures contract may be adversely affected by "daily price fluctuation limits"
established by commodity exchanges which limit the amount of 

                                      B-5
<PAGE>
 
fluctuation in a futures contract price during a single trading day. Once the
daily limit has been reached in the contract, no trades may be entered into at a
price beyond the limit, thus preventing the liquidation of open futures
positions. The trading of futures contracts is also subject to the risk of
trading halts, suspensions, exchange or clearing house equipment failures,
government intervention, insolvency of a brokerage firm or clearing house or
other disruptions of normal activity, which could at times make it difficult or
impossible to liquidate existing positions or to recover excess variation margin
payments.
    
     Successful use of futures by the Funds is also subject to the Advisor's or
Sub-Advisor's ability to predict correctly movements in the direction of the
market.  For example, if a particular Fund has hedged against the possibility of
a decline in the market adversely affecting securities held by it and securities
prices increase instead, the Fund will lose part or all of the benefit to the
increased value of its securities which it has hedged because it will have
offsetting losses in its futures positions.  In addition, in such situations, if
the Fund has insufficient cash, it may have to sell securities to meet daily
variation margin requirements.  Such sales of securities may be, but will not
necessarily be, at increased prices which reflect the rising market.  The Funds
may have to sell securities at a time when they may be disadvantageous to do so.
                                                                                
V. Options on Futures Contracts
   ----------------------------

     The Funds may purchase and write options on the futures contracts described
above.  A futures option gives the holder, in return for the premium paid, the
right to buy (call) from or sell (put) to the writer of the option a futures
contract at a specified price at any time during the period of the option.  Upon
exercise, the writer of, the option is obligated to pay the difference between
the cash value of the futures contract and the exercise price.  Like the buyer
or seller of a futures contract, the holder, or writer, of an option has the
right to terminate its position prior to the scheduled expiration of the option
by selling, or purchasing an option of the same series, at which time the person
entering into the closing transaction will realize a gain or loss.  A Fund will
be required to deposit initial margin and variation margin with respect to put
and call options on futures contracts written by it pursuant to brokers'
requirements similar to those described above.  Net option premiums received
will be included as initial margin deposits.

     Investments in futures options involve some of the same considerations that
are involved in connection with investments in future contracts (for example,
the existence of a liquid secondary market).  In addition, the purchase or sale
of an option also entails the risk that changes in the value of the underlying
futures contract will not correspond to changes in the value of the option
purchased.  Depending on the pricing of the option compared to either the
futures contract upon which it is based, or upon the price of the securities
being hedged, an option may or may not be less risky than ownership of the
futures contract or such securities.  In general, the market prices of options
can be expected to be more volatile than the market prices on underlying futures
contract.  Compared to the purchase or sale of futures contracts, however, the
purchase of call or put options on futures contracts may frequently involve less
potential risk to the Fund because the maximum amount at risk is the premium
paid for the options (plus transaction costs).  The writing of an option on a
futures contract involves risks similar to those risks relating to the sale of
futures contracts.

VI. Currency Transactions
    ---------------------

     The Fund may engage in currency transactions in order to hedge the value of
portfolio holdings denominated in particular currencies against fluctuations in
relative value.  Currency transactions include forward currency contracts,
currency futures, options on currencies, and currency swaps.  A forward currency
contract involves a privately negotiated obligation to purchase or sell (with
delivery generally required) a specific currency at a future date, which may be
any fixed number of days from the date of the contract agreed upon by the
parties, at a price set at the time of the contract.  A currency swap is an
agreement to exchange cash flows based on the notional difference among two or
more currencies and operates similarly to an interest rate swap as described in
the Statement of Additional Information.  The Fund may enter into currency
transactions with counterparties which have received (or the guarantors of the
obligations which have received) a credit rating of A-1 or P-1 by S&P or
Moody's, respectively, or that have an equivalent rating from a NRSRO or are
determined to be of equivalent credit quality by the Advisor.

                                      B-6
<PAGE>
 
     The Fund's dealings in forward currency contracts and other currency
transactions such as futures, options, options on futures and swaps will be
limited to hedging involving either specific transactions or portfolio
positions.  Transaction hedging is entering into a currency transaction with
respect to specific assets or liabilities of the Fund, which will generally
arise in connection with the purchase or sale of its portfolio securities or the
receipt of income therefrom.  Position hedging is entering into a currency
transaction with respect to portfolio security positions denominated or
generally quoted in that currency.

     The Fund will not enter into a transaction to hedge currency exposure to an
extent greater after netting all transactions intended wholly or partially to
offset other transactions, than the aggregate market value (at the time of
entering into the transaction) of the securities held in its portfolio that are
denominated or generally quoted in or currently convertible into such currency,
other than with respect to proxy hedging as described below.

     The Fund may also cross-hedge currencies by entering into transactions to
purchase or sell one or more currencies that are expected to decline in value
relative to other currencies to which the Fund has or in which the Fund expects
to have portfolio exposure.

     To reduce the effect of currency fluctuations on the value of existing or
anticipated holdings of portfolio securities, the Fund may also engage proxy
hedging.  Proxy hedging is often used when the currency to which the Fund's
portfolio is exposed is difficult to hedge or to hedge against the dollar.
Proxy hedging entails entering into a commitment or option to sell a currency
whose changes in value are generally considered to be correlated to a currency
or currencies in which some or all of the Fund's portfolio securities are or are
expected to be denominated, in exchange for U.S. dollars.  The amount of the
commitment or option would not exceed the value of the Fund's securities
denominated in correlated currencies.  For example, if the Advisor or Sub-
Advisor considers that the Austrian schilling is correlated to the German mark
(the "D-mark"), the Fund holds securities denominated in shillings and the
Advisor or Sub-Advisor believes that the value of the schillings will decline
against the U.S. dollar, the Advisor or Sub-Advisor may enter into a commitment
or option to sell D-marks and buy dollars.  Currency hedging involves some of
the same risks and considerations as other transactions with similar
instruments.  Currency transactions can result in losses to the Fund if the
currency being hedged fluctuates in value to a degree or in a direction that is
not anticipated.  Further, there is the risk that the perceived correlation
between various currencies may not be present or may not be present during the
particular time that the Fund is engaging in proxy hedging.  If a Fund enters
into a currency hedging transaction, the Fund will earmark liquid, high grade
assets on the books of the Fund or the Fund's sub-custodian to the extent the
Fund's obligations are not otherwise "covered" through ownership of the
underlying currency.

     Currency transactions are subject to risks different from those of other
portfolio transactions.  Because currency control is of great importance to the
issuing governments and influences economic planning and policy, purchases and
sales of currency and related instruments can be negatively affected by
government exchange controls, blockages, and manipulations or exchange
restrictions imposed by governments.  These can result in losses to the Fund if
it is unable to deliver or receive currency or funds in settlement of
obligations and could also cause hedges it has entered into to be rendered
useless, resulting in full currency exposure as well as incurring transaction
costs.  Buyers and sellers of currency futures are subject to the same risks
that apply to the use of futures generally.  Further, settlement of a currency
futures contract for the purchase of most currencies must occur at a bank based
in the issuing nation.  Trading options on currency futures is relatively new,
and the ability to establish and close to positions on such options is subject
to the maintenance of a liquid market which may not always be available.
Currency exchange rates may fluctuate based on factors extrinsic to that
country's economy.

VII. Other Matters
     -------------

     Accounting for futures contracts will be in accordance with generally
accepted accounting principles.

February 1990 to "Ambassador Funds" and in June 1995 to "The Munder Funds
Trust."
    
     As stated in each Prospectus, the investment advisor of the Fund is Munder
Capital Management (the "Advisor").  The principal partners of the Advisor are
Old MCM, Inc. ("MCM"), Munder Group LLC, WAM Holdings, Inc. ("WAM") and WAM
Holdings II ("WAM II").  MCM was founded in April 1985 as a Delaware corporation
and was a registered investment advisor.  WAM and WAM II are indirect, wholly-
owned subsidiaries of Comerica Incorporated which owns or controls approximately
88% of the partnership interests in the Advisor.    

     Capitalized terms used in this Statement of Additional Information and not
otherwise defined have the same meanings as are given to them in each
Prospectus.

                               FUND INVESTMENTS

     The following supplements the information contained in each Prospectus
concerning the investment objective and policies of the Fund.  The Fund's
investment objective is a non-fundamental policy and may be changed without the
authorization of the holders of a majority of the Fund's outstanding shares.
All other investment policies, other than those specifically designated as
fundamental, are non-fundamental policies and may be changed without the
authorization of the holders of a majority of the Fund's outstanding shares.
There can be no assurance that the Fund will achieve its objective.  A
description of applicable credit ratings is set forth in Appendix A to this
Statement of Additional Information.

     BORROWING.  The Fund is authorized to borrow money in amounts up to 5% of
the value of its total assets at the time of such borrowings for temporary
purposes, and is authorized to borrow money in excess of the 5% limit as
permitted by the Investment Company Act of 1940, as amended (the "1940 Act"), to
meet redemption requests.  This borrowing may be unsecured.  The 1940 Act
requires the Fund to maintain continuous asset coverage of 300% of the amount
borrowed.  If the 300% asset coverage should decline as a result of market
fluctuations or other reasons, the Fund may be required to sell some of its
portfolio holdings within three days to reduce the debt and restore the 300%
asset coverage, even though it may be disadvantageous from an investment
standpoint to sell securities at that time.  Borrowed funds are subject to
interest costs that may or may not be offset by amounts earned on the borrowed
funds.  The Fund may also be required to maintain minimum average balances in
connection with such borrowing or to pay a commitment or other fees to maintain
a line of credit; either of these requirements would increase the cost of
borrowing over the stated interest rate.  The Fund may, in connection with
permissible borrowings, transfer as collateral securities owned by the Fund.

     FOREIGN SECURITIES.  The Fund may invest up to 25% of its assets in foreign
securities.  The Fund typically will only purchase foreign securities which are
represented by American Depositary Receipts ("ADRs") listed on a domestic
securities exchange or included in the NASDAQ National Market System, or foreign
securities listed directly on a domestic securities exchange or included in the
NASDAQ National Market System.  ADRs are receipts typically issued by a United
States bank or trust company evidencing ownership of the underlying foreign
securities.  Certain institutions issuing ADRs may not be sponsored by the
issuer.  A non-sponsored depositary may not provide the same shareholder
information that a sponsored depositary is required to provide under its
contractual arrangements with the issuer.

     The Fund may also purchase Global Depositary Receipts ("GDRs") or European
Depositary Receipts ("EDRs"), which are receipts issued by European financial
institutions evidencing ownership of the underlying foreign securities.

                                       3

     Income and gains on foreign securities may be subject to foreign
withholdings taxes.  Investors should consider carefully the substantial risks
involved in securities of companies and governments of foreign nations, which
are in addition to the usual risks inherent in domestic investments.

     There may be less publicly available information about foreign companies
comparable to the reports and ratings published about companies in the United
States.  Foreign companies are not generally subject to uniform accounting,
auditing and financial reporting standards, and auditing practices and
requirements may not be comparable to those applicable to United States
companies.  Foreign markets have substantially less volume than the New York
Stock Exchange and securities of some foreign companies are less liquid and more
volatile than securities of comparable United States companies.  Commission
rates in foreign countries, which are generally fixed rather than subject to
negotiation as in the United States, are likely to be higher.  In many foreign
countries there is less government supervision and regulation of stock
exchanges, brokers, and listed companies than in the United States.  Such
concerns are particularly heightened for emerging markets and Eastern European
countries.

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

     Investments in Eastern European countries may involve risks of
nationalization, expropriation and confiscatory taxation.  The Communist
governments of a number of Eastern European countries expropriated large amounts
of private property in the past, in many cases without adequate compensation,
and there can be no assurance that such expropriation will not occur in the
future.  In the event of such expropriation, the Fund could lose a substantial
portion of any investments it has made in the affected countries.  Further, no
accounting standards exist in Eastern European countries.  Finally, even though
certain Eastern European currencies may be convertible into United States
dollars, the conversion rates may be artificial to the actual market values and
may be adverse to the Fund.

     The Advisor endeavors to buy and sell foreign currencies on as favorable a
basis as practicable.  Some price spread on currency exchange (to cover service
charges) may be incurred, particularly when the Fund changes investments from
one country to another or when proceeds of the sale of Fund shares in U.S.
dollars are used for the purchase of securities in foreign countries.  Also,
some countries may adopt policies which would prevent the Fund from transferring
cash out of the country or withhold portions of interest and dividends at the
source.  There is the possibility of expropriation, nationalization or
confiscatory taxation, withholding and other foreign taxes on income or other
amounts, foreign exchange controls (which may include suspension of the ability
to transfer currency from a given country), default in foreign government
securities, political or social instability or diplomatic developments that
could affect investments in securities of issuers in foreign nations.

     Foreign securities markets have different clearance and settlement
procedures, and in certain markets there have been times when settlements have
been unable to keep pace with the volume of securities transactions, making it
difficult to conduct such transactions.  Delays in settlement could result in
temporary periods when assets of the Fund are uninvested and no return is earned
thereon.  The inability of the Fund to make intended security purchases due to
settlement problems could cause the Fund to miss attractive investment
opportunities.  Inability to dispose of portfolio securities due to settlement
problems could result either in losses to the Fund due to subsequent declines in
value of the portfolio security or, if the fund has entered into a contract to
sell the security, could result in possible liability to the purchaser.

                                       4

     The Fund may be affected either unfavorably or favorably by fluctuations in
the relative rates of exchange between the currencies of different nations, by
exchange control regulations and by indigenous economic and political
developments.  Changes in foreign currency exchange rates will influence values
within the Fund from the perspective of U.S. investors, and may also affect the
value of dividends and interest earned, gains and losses realized on the sale of
securities, and net investment income and gains, if any, to be distributed to
shareholders by the Fund.  The rate of exchange between the U.S. dollar and
other currencies is determined by the forces of supply and demand in the foreign
exchange markets.  These forces are affected by the international balance of
payments and other economic and financial conditions, government intervention,
speculation and other factors.  The Advisor will attempt to avoid unfavorable
consequences and to take advantage of favorable developments in particular
nations where, from time to time, it places the Fund's investments.

     The exercise of this flexible policy may include decisions to purchase
securities with substantial risk characteristics and other decisions such as
changing the emphasis on investments from one nation to another and from one
type of security to another.  Some of these decisions may later prove profitable
and others may not.  No assurance can be given that profits, if any, will exceed
losses.

     FORWARD FOREIGN CURRENCY TRANSACTIONS.  In order to protect against a
possible loss on investments resulting from a decline or appreciation in the
value of a particular foreign currency against the U.S. dollar or another
foreign currency, the Fund is authorized to enter into forward foreign currency
exchange contracts ("forward currency contracts").  These contracts involve an
obligation to purchase or sell a specified currency at a future date at a price
set at the time of the contract.  Forward currency contracts do not eliminate
fluctuations in the values of portfolio securities but rather allow the Fund to
establish a rate of currency exchange for a future point in time.

     When entering into a contract for the purchase or sale of a security, the
Fund may enter into a forward currency contract for the amount of the purchase
or sale price to protect against variations, between the date the security is
purchased or sold and the date on which payment is made or received, in the
value of the foreign currency relative to the U.S. dollar or other foreign
currency.

     When the Advisor anticipates that a particular foreign currency may decline
substantially relative to the U.S. dollar or other leading currencies, in order
to reduce risk, the Fund may enter into a forward contract to sell, for a fixed
amount, the amount of foreign currency approximating the value of some or all of
the Fund's securities denominated in such foreign currency.  Similarly, when the
obligations held by the Fund create a short position in a foreign currency, the
Fund may enter into a forward contract to buy, for a fixed amount, an amount of
foreign currency approximating the short position.  With respect to any forward
currency contract, it will not generally be possible to match precisely the
amount covered by that contract and the value of the securities involved due to
the changes in the values of such securities resulting from market movements
between the date the forward contract is entered into and the date it matures.
In addition, while forward contracts may offer protection from losses resulting
from declines or appreciation in the value of a particular foreign currency,
they also limit potential gains which might result from changes in the value of
such currency.  The Fund will also incur costs in connection with forward
currency contracts and conversions of foreign currencies and U.S. dollars.
    
     Cash or liquid securities equal to the amount of the Fund's assets that
could be required to consummate forward contracts will be designated on the
records of the Fund or established with the Fund's sub-custodian except to the
extent the contracts are otherwise "covered."  For the purpose of determining
the adequacy of designated securities, the designated securities will be valued
at market or fair value.  If the market or fair value of such securities
declines, additional cash or securities will be designated daily so that the
value of the designated securities will equal the amount of such commitments by
the Fund.  A forward contract to sell a foreign currency is "covered" if the
Fund owns the currency (or securities denominated in the currency) underlying
the contract, or holds a forward contract (or call option) permitting the Fund
to buy the same currency at a price no higher than the Fund's price to sell the
currency.  A forward contract to buy a foreign currency is "covered" if the Fund
holds a forward contract (or put option) permitting the Fund to sell the same
currency at a price as high as or higher than the Fund's price to buy the
currency.     

                                       5

     FUTURES CONTRACTS AND RELATED OPTIONS.  The Fund may purchase and sell
futures contracts on interest-bearing securities or securities indices, and may
purchase and sell call and put options on futures contracts.  For a detailed
description of futures contracts and related options, see Appendix B to this
Statement of Additional Information.

     ILLIQUID SECURITIES. The Fund may invest up to 15% of the value of its net
assets (determined at time of acquisition) in securities that are illiquid.
Illiquid securities would generally include securities for which there is a
limited trading market, repurchase agreements and time deposits with
notice/termination dates in excess of seven days, and certain securities that
are subject to trading restrictions because they are not registered under the
Securities Act of 1933, as amended (the "Act").  If, after the time of
acquisition, events cause this limit to be exceeded, the Fund will take steps to
reduce the aggregate amount of illiquid securities as soon as reasonably
practicable in accordance with the policies of the SEC.

     The Fund may invest in commercial obligations issued in reliance on the
"private placement" exemption from registration afforded by Section 4(2) of the
Act ("Section 4(2) paper").  The Fund may also purchase securities that are not
registered under the Act, but which can be sold to qualified institutional
buyers in accordance with Rule 144A under the Act, ("Rule 144A securities").
Section 4(2) paper is restricted as to disposition under the Federal securities
laws, and generally is sold to institutional investors who agree that they are
purchasing the paper for investment and not with a view to public distribution.
Any resale by the purchaser must be in an exempt transaction.  Section 4(2)
paper normally is resold to other institutional investors through or with the
assistance of the issuer or investment dealers which make a market in the
Section 4(2) paper, thus providing liquidity.  Rule 144A securities generally
must be sold only to other qualified institutional buyers.  If a particular
investment in Section 4(2) paper or Rule 144A securities is not determined to be
liquid, that investment will be included within the Fund's limitation on
investment in illiquid securities.  The Advisor will determine the liquidity of
such investments pursuant to guidelines established by the Boards of Trustees.
It is possible that unregistered securities purchased by the Fund in reliance
upon Rule 144A could have the effect of increasing the level of the Fund's
illiquidity to the extent that qualified institutional buyers become, for a
period, uninterested in purchasing these securities.

     INVESTMENT COMPANY SECURITIES.  The Fund may invest in securities issued by
other investment companies.  As a shareholder of another investment company, the
Fund would bear its pro rata portion of the other investment company's expenses,
including advisory fees.  These expenses would be in addition to the expenses
the Fund bears directly in connection with its own operations.  The Fund
currently intends to limit its investments in securities issued by other
investment companies so that, as determined immediately after a purchase of such
securities is made: (i) not more than 5% of the value of the Fund's total assets
will be invested in the securities of any one investment company; (ii) not more
than 10% of the value of its total assets will be invested in the aggregate in
securities of investment companies as a group; and (iii) not more than 3% of the
outstanding voting stock of any one investment company will be owned by the
Fund.

     LENDING OF PORTFOLIO SECURITIES.  To enhance the return on its portfolio,
the Fund may lend securities in its portfolio (subject to a limit of 25% of the
Fund's total assets) to securities firms and financial institutions, provided
that each loan is secured continuously by collateral in the form of cash, high
quality money market instruments or short-term U.S. Government securities
adjusted daily to have a market value at least equal to the current market value
of the securities loaned.  These loans are terminable at any time, and the Fund
will receive any interest or dividends paid on the loaned securities.  In
addition, it is anticipated that the Fund may share with the borrower some of
the income received on the collateral for the loan or the Fund will be paid a
premium for the loan.  The risk in lending portfolio securities, as with other
extensions of credit, consists of possible delay in recovery of the securities
or possible loss of rights in the collateral should the borrower fail
financially.  In determining whether the Fund will lend securities, the Advisor
will consider all relevant facts and circumstances.  The Fund will only enter
into loan arrangements with broker-dealers, banks or other institutions which
the Advisor has determined are creditworthy under guidelines established by the
Boards of Trustees.

     LOWER-RATED DEBT SECURITIES.  It is expected that the Fund will invest not
more than 5% of its total assets in securities that are rated below investment
grade by Standard & Poor's Rating Service, a division of McGraw-Hill Companies,
Inc. ("S&P"), or Moody's Investors Service, Inc. ("Moody's"), or in comparable
unrated securities.  

                                       6
<PAGE>
 
Such securities are also known as junk bonds. The yields on lower-rated debt and
comparable unrated securities generally are higher than the yields available on
higher-rated securities. However, investments in lower-rated debt and comparable
unrated securities generally involve greater volatility of price and risk of
loss of income and principal, including the possibility of default by or
bankruptcy of the issuers of such securities. Lower-rated debt and comparable
unrated securities (a) will likely have some quality and protective
characteristics that, in the judgment of the rating organization, are outweighed
by large uncertainties or major risk exposures to adverse conditions and (b) are
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. Accordingly,
it is possible that these types of factors could, in certain instances, reduce
the value of securities held in the Fund's portfolio, with a commensurate effect
on the value of the Fund's shares. Therefore, an investment in the Fund should
not be considered as a complete investment program and may not be appropriate
for all investors.

     While the market values of lower-rated debt and comparable unrated
securities tend to react more to fluctuations in interest rate levels than the
market values of higher-rated securities, the market values of certain lower
rated debt and comparable unrated securities also tend to be more sensitive to
individual corporate developments and changes in economic conditions than
higher-rated securities.  In addition, lower-rated debt securities and
comparable unrated securities generally present a higher degree of credit risk.
Issuers of lower-rated debt and comparable unrated securities often are highly
leveraged and may not have more traditional methods of financing available to
them so that their ability to service their debt obligations during an economic
downturn or during sustained periods of rising interest rates may be impaired.
The risk of loss due to default by such issuers is significantly greater because
lower-rated debt and comparable unrated securities generally are unsecured and
frequently are subordinated to the prior payment of senior indebtedness.  The
Fund may incur additional expenses to the extent it is required to seek recovery
upon a default in the payment of principal or interest on its portfolio
holdings.  The existence of limited markets for lower-rated debt and comparable
unrated securities may diminish the Fund's ability to (a) obtain accurate market
quotations for purposes of valuing such securities and calculating its net asset
value and (b) sell the securities at fair value either to meet redemption
requests or to respond to changes in the economy or in financial markets.
    
     Lower-rated debt securities and comparable unrated securities may have call
or buy-back features that permit their issuers to call or repurchase the
securities from their holders.  If an issuer exercises these rights during
periods of declining interest rates, the Fund may have to replace the security
with a lower yielding security, thus resulting in a decreased return to the
Fund.  A description of applicable credit ratings is set forth in Appendix A of
this Statement of Additional Information.     

     MONEY MARKET INSTRUMENTS.  As described in the Prospectuses, the Fund may
invest from time to time in "money market instruments," a term that includes,
among other things, bank obligations, commercial paper, variable amount master
demand notes and corporate bonds with remaining maturities of 397 days or less.

     Bank obligations include bankers' acceptances, negotiable certificates of
deposit and non-negotiable time deposits, including U.S. dollar-denominated
instruments issued or supported by the credit of U.S. or foreign banks or
savings institutions.  Although the Fund will invest in obligations of foreign
banks or foreign branches of U.S. banks only where the Advisor deems the
instrument to present minimal credit risks, such investments may nevertheless
entail risks that are different from those of investments in domestic
obligations of U.S. banks due to differences in political, regulatory and
economic systems and conditions.  All investments in bank obligations are
limited to the obligations of financial institutions having more than $1 billion
in total assets at the time of purchase.
    
     Investments by the Fund in commercial paper will consist of issues rated at
the time of purchase A-1 and/or P-1 by S&P or Moody's. In addition, the Fund may
acquire unrated commercial paper and corporate bonds that are determined by the
Advisor at the time of purchase to be of comparable quality to rated instruments
that may be acquired by the Fund as previously described.     

     The Fund may also purchase variable amount master demand notes which are
unsecured instruments that permit the indebtedness thereunder to vary and
provide for periodic adjustments in the interest rate.  Although the notes are
not normally traded and there may be no secondary market in the notes, the Fund
may demand payment of 

                                       7
<PAGE>
 
the principal of the instrument at any time. The notes are not typically rated
by credit rating agencies, but issuers of variable amount master demand notes
must satisfy the same criteria as set forth above for issuers of commercial
paper. If an issuer of a variable amount master demand note defaulted on its
payment obligation, the Fund might be unable to dispose of the note because of
the absence of a secondary market and might, for this or other reasons, suffer a
loss to the extent of the default. The Fund invests in variable amount master
notes only when the Advisor deems the investment to involve minimal credit risk.
    
     MORTGAGE-RELATED  SECURITIES.  There are a number of important differences
among the agencies and instrumentalities of the U.S. Government that issue
mortgage-related securities and among the securities that they issue.  Mortgage-
related securities guaranteed by the Government National Mortgage Association
("GNMA") include GNMA Mortgage Pass-Through Certificates (also known as "Ginnie
Maes") which are guaranteed as to the timely payment of principal and interest
by GNMA and such guarantee is backed by the full faith and credit of the United
States.  GNMA is a wholly-owned U.S. Government corporation within the
Department of Housing and Urban Development.  GNMA certificates also are
supported by the authority of GNMA to borrow funds from the U.S. Treasury to
make payments under its guarantee.  Mortgage-related securities issued by the
Federal National Mortgage Association ("FNMA") include FNMA Guaranteed Mortgage
Pass-Through Certificates (also known as "Fannie Maes") which are solely the
obligations of the FNMA and are not backed by or entitled to the full faith and
credit of the United States, but are supported by the right of the issuer to
borrow from the U.S. Treasury.  FNMA is a government-sponsored organization
owned entirely by private stockholders.  Fannie Maes are guaranteed as to timely
payment of the principal and interest by FNMA.  Mortgage-related securities
issued by the Federal Home Loan Mortgage Corporation ("FHLMC") include FHLMC
Mortgage Participation Certificates (also known as "Freddie Macs" or "PCs").
FHLMC is a corporate instrumentality of the United States, created pursuant to
an Act of Congress, which is owned entirely by Federal Home Loan Banks.  Freddie
Macs are not guaranteed by the United States or by any Federal Home Loan Banks
and do not constitute a debt or obligation of the United States or of any
Federal Home Loan Bank.  Freddie Macs entitle the holder to timely payment of
interest, which is guaranteed by the FHLMC.  FHLMC guarantees either ultimate
collection or timely payment of all principal payments on the underlying
mortgage loans.  When FHLMC does not guarantee timely payment of principal,
FHLMC may remit the amount due on account of its guarantee of ultimate payment
of principal at any time after default on an underlying mortgage, but in no
event later than one year after it becomes payable.     

     MUNICIPAL OBLIGATIONS.  Opinions relating to the validity of municipal
obligations and to the exemption of interest thereon from regular Federal income
tax are rendered by bond counsel or counsel to the respective issuers at the
time of issuance.  Neither the Trust nor the Advisor will review the proceedings
relating to the issuance of municipal obligations or the bases for such
opinions.

     An issuer's obligations under its municipal obligations are subject to the
provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of creditors, such as the Federal Bankruptcy Code, and laws, if any,
which may be enacted by Federal or state legislatures extending the time for
payment of principal or interest, or both, or imposing other constraints upon
enforcement of such obligations or upon the ability of municipalities to levy
taxes.  The power or ability of an issuer to meet its obligations for the
payment of interest on and principal of its municipal obligations may be
materially adversely affected by litigation or other conditions.

     From time to time proposals have been introduced before Congress for the
purpose of restricting or eliminating the Federal income tax exemption for
interest on municipal obligations. For example, under the Tax Reform Act of 1986
interest on certain private activity bonds must be included in an investor's
Federal alternative minimum taxable income, and corporate investors must include
all tax-exempt interest in their Federal alternative minimum taxable income. The
Trust cannot predict what legislation, if any, may be proposed in Congress in
the future as regards the Federal income tax status of interest on municipal
obligations in general, or which proposals, if any, might be enacted.

     NON-DOMESTIC BANK OBLIGATIONS.  Non-domestic bank obligations include
Eurodollar Certificates of Deposit ("ECDs"), which are U.S. dollar-denominated
certificates of deposit issued by offices of foreign and domestic banks located
outside the United States; Eurodollar Time Deposits ("ETDs"), which are U.S.
dollar-denominated deposits in a foreign branch of a U.S. bank or a foreign
bank; Canadian Time Deposits ("CTDs"), 

                                       8
<PAGE>
 
which are essentially the same as ETDs except they are issued by Canadian
offices of major Canadian banks; Schedule Bs which are obligations issued by
Canadian branches of foreign or domestic banks; Yankee Certificates of Deposit
("Yankee CDs"), which are U.S. dollar-denominated certificates of deposit issued
by a U.S. branch of a foreign bank and held in the United States; and Yankee
Bankers' Acceptances ("Yankee BAs"), which are U.S. dollar denominated bankers'
acceptances issued by a U.S. branch of a foreign bank and held in the United
States.

     OPTIONS.  The Fund may write covered call options, buy put options, buy
call options and write secured put options.  Such options may relate to
particular securities and may or may not be listed on a national securities
exchange and issued by the Options Clearing Corporation.  Options trading is a
highly specialized activity which entails greater than ordinary investment risk.
Options on particular securities may be more volatile than the underlying
securities, and therefore, on a percentage basis, an investment in options may
be subject to greater fluctuation than an investment in the underlying
securities themselves.  For risks associated with options on foreign currencies,
see Appendix B to this Statement of Additional Information.
    
     A call option for a particular security gives the purchaser of the option
the right to buy, and the writer of the option the obligation to sell, the
underlying security at the stated exercise price at any time prior to the
expiration of the option, regardless of the market price of the security.  The
premium paid to the writer is in consideration for undertaking the obligations
under the option contract.  A put option for a particular security gives the
purchaser the right to sell and the writer of the option the obligation to buy,
the underlying security at the stated exercise price at any time prior to the
expiration date of the option, regardless of the market price of the 
security.     

     The writer of an option that wishes to terminate its obligation may effect
a "closing purchase transaction." This is accomplished by buying an option of
the same series as the option previously written.  The effect of the purchase is
that the writer's position will be canceled by the clearing corporation.
However, a writer may not effect a closing purchase transaction after being
notified of the exercise of an option.  Likewise, an investor who is the holder
of an option may liquidate its position by effecting a "closing sale
transaction." The cost of such a closing purchase plus transaction costs may be
greater than the premium received upon the original option, in which event the
Fund will have incurred a loss in the transaction.  There is no guarantee that
either a closing purchase or a closing sale transaction can be effected.

     Effecting a closing transaction in the case of a written call option will
permit the Fund to write another call option on the underlying security with
either a different exercise price or expiration date or both, or in the case of
a written put option, will permit the Fund to write another put option to the
extent that the exercise price thereof is secured by deposited cash or short-
term securities.  Also, effecting a closing transaction will permit the cash or
proceeds from the concurrent sale of any securities subject to the option to be
used for other Fund investments.  If the Fund desires to sell a particular
security from its portfolio on which it has written a call option, it will
effect a closing transaction prior to or concurrent with the sale of the
security.

     The Fund may write options in connection with buy-and-write transactions;
that is, the Fund may purchase a security and then write a call option against
that security.  The exercise price of the call the Fund determines to write will
depend upon the expected price movement of the underlying security.  The
exercise price of a call option may be below ("in-the-money"), equal to ("at-
the-money") or above ("out-of-the-money") the current value of the underlying
security at the time the option is written.  Buy-and-write transactions using
in-the-money call options may be used when it is expected that the price of the
underlying security will remain flat or decline moderately during the option
period.  Buy-and-write transactions using out-of-the-money call options may
be used when it is expected that the premiums received from writing the call
option plus the appreciation in the market price of the underlying security up
to the exercise price will be greater than the appreciation in the price of the
underlying security alone.  If the call options are exercised in such
transactions, the maximum gain to the Fund will be the premium received by it
for writing the option, adjusted upwards or downwards by the difference between
the Fund's purchase price of the security and the exercise price.  If the
options are not exercised and the price of the underlying security declines, the
amount of such decline will be offset in part, or entirely, by the premium
received.

     In the case of a call option on a security, the option is "covered" if the
Fund owns the security underlying the call or has an absolute and immediate
right to acquire that security without additional cash consideration (or, if

                                       9
<PAGE>
 
    
additional cash consideration is required, cash or liquid securities in such
amount as are earmarked on the books of the Fund or the Fund's sub-custodian)
upon conversion or exchange of other securities held by it.  For a call option
on an index, the option is covered if the Fund maintains with its sub-custodian
cash or liquid securities equal to the contract value.  A call option is also
covered if the Fund holds a call on the same security or index as the call
written where the exercise price of the call held is (i) equal to or less than
the exercise price of the call written, or (ii) greater than the exercise price
of the call written provided the difference is cash or liquid securities is
earmarked on the books of the Fund or the Fund's sub-custodian.  The Fund will
limit its investment in uncovered call options purchased or written by the Fund
to 33 1/3% of the Fund's total assets.  The Fund will write put options only if
they are "secured" by cash or liquid securities earmarked on the books of the
Fund or the Fund's sub-custodian in an amount not less than the exercise price
of the option at all times during the option period.     

     The writing of covered put options is similar in terms of risk/return
characteristics to buy-and-write transactions.  If the market price of the
underlying security rises or otherwise is above the exercise price, the put
option will expire worthless and the Fund's gain will be limited to the premium
received.  If the market price of the underlying security declines or otherwise
is below the exercise price, the Fund may elect to close the position or take
delivery of the security at the exercise price and the Fund's return will be the
premium received from the put option minus the amount by which the market price
of the security is below the exercise price.

     The Fund may purchase put options to hedge against a decline in the value
of its portfolio.  By using put options in this way, the Fund will reduce any
profit it might otherwise have realized in the underlying security by the amount
of the premium paid for the put option and by transaction costs.  The Fund may
purchase call options to hedge against an increase in the price of securities
that it anticipates purchasing in the future.  The premium paid for the call
option plus any transaction costs will reduce the benefit, if any, realized by
the Fund upon exercise of the option, and, unless the price of the underlying
security rises sufficiently, the option may expire worthless to the Fund.

     When the Fund purchases an option, the premium paid by it is recorded as an
asset of the Fund.  When the Fund writes an option, an amount equal to the net
premium (the premium less the commission) received by the Fund is included in
the liability section of the Fund's statement of assets and liabilities as a
deferred credit.  The amount of this asset or deferred credit will be
subsequently marked-to-market to reflect the current value of the option
purchased or written.  The current value of the traded option is the last sale
price or, in the absence of a sale, the average of the closing bid and asked
prices.  If an option purchased by the Fund expires unexercised the Fund
realizes a loss equal to the premium paid.  If the Fund enters into a closing
sale transaction on an option purchased by it, the Fund will realize a gain if
the premium received by the Fund on the closing transaction is more than the
premium paid to purchase the option, or a loss if it is less.  If an option
written by the Fund expires on the stipulated expiration date or if the Fund
enters into a closing purchase transaction, it will realize a gain (or loss if
the cost of a closing purchase transaction exceeds the net premium received when
the option is sold) and the deferred credit related to such option will be
eliminated.  If an option written by the Fund is exercised, the proceeds of the
sale will be increased by the net premium originally received and the Fund will
realize a gain or loss.

     There are several risks associated with transactions in options on
securities and indices. 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. An option writer, unable to effect a closing purchase transaction,
will not be able to sell the underlying security (in the case of a covered call
option) or liquidate the earmarked securities (in the case of a secured put
option) until the option expires or the optioned security is delivered upon
exercise with the result that the writer in such circumstances will be subject
to the risk of market decline or appreciation in the security during such
period.

     There is no assurance that the Fund will be able to close an unlisted
option position.  Furthermore, unlisted options are not subject to the
protections afforded purchasers of listed options by the Options Clearing
Corporation, which performs the obligations of its members who fail to do so in
connection with the purchase or sale of options.

     In addition, a liquid secondary market for particular options, whether
traded over-the-counter or on a national securities exchange ("Exchange") may be
absent for reasons which include the following: there may be 

                                       10
<PAGE>
 
    
insufficient trading interest in certain options; restrictions may be imposed by
an Exchange on opening transactions or closing transactions or both; trading
halts, suspensions or other restrictions may be imposed with respect to
particular classes or series of options or underlying securities; unusual or
unforeseen circumstances may interrupt normal operations on an Exchange; the
facilities of an Exchange or the Options Clearing Corporation may not at all
times be adequate to handle current trading volume; or one or more Exchanges
could, for economic or other reasons, decide or be compelled at some future date
to discontinue the trading of options (or a particular class or series of
options), in which event the secondary market on that Exchange (or in that class
or series of options) would cease to exist, although outstanding options that
had been issued by the Options Clearing Corporation as a result of trades on
that Exchange would continue to be exercisable in accordance with their terms.

     Currency transactions, including options on currencies and currency
futures, are subject to risks different from those of other portfolio
transactions.  Because currency control is of great importance to the issuing
governments and influences economic planning and policy, purchases and sales of
currency and related instruments can be negatively affected by government
exchange controls, blockages, and manipulations or exchange restrictions imposed
by governments.  These can result in losses to the Fund if it is unable to
deliver or receive currency or funds in settlement of obligations and could also
cause hedges it has entered into to be rendered useless, resulting in full
currency exposure as well as the incurring of transaction costs.  Buyers and
sellers of currency futures are subject to the same risks that apply to the use
of futures generally.  Further, settlement of a currency futures contract for
the purchase of most currencies must occur at a bank based in the issuing
nation.  Trading options on currency futures is relatively new, and the ability
to establish and close out positions on such options is subject to the
maintenance of a liquid market which may not always be available.  Currency
exchange rates may fluctuate based on factors extrinsic to the issuing country's
economy.

     REPURCHASE AGREEMENTS.  The Fund may agree to purchase securities from
financial institutions such as member banks of the Federal Reserve System, any
foreign bank or any domestic or foreign broker/dealer that is recognized as a
reporting government securities dealer, subject to the seller's agreement to
repurchase them at an agreed-upon time and price ("repurchase agreements").  The
Advisor will review and continuously monitor the creditworthiness of the seller
under a repurchase agreement, and will require the seller to maintain collateral
in an amount that is greater than the repurchase price.  Default by, or
bankruptcy of, the seller would, however, expose the Fund to possible loss
because of adverse market action or delays in connection with the disposition of
underlying obligations except with respect to repurchase agreements secured by
U.S. Government securities.     

     The repurchase price under repurchase agreements generally equals the price
paid by the Fund plus interest negotiated on the basis of current short-term
rates (which may be more or less than the rate on the securities underlying the
repurchase agreement).

     Securities subject to repurchase agreements will be held, as applicable, by
the Trust's custodian (or sub-custodian) in the Federal Reserve/Treasury book-
entry system or by another authorized securities depositary.  Repurchase
agreements are considered to be loans by the Fund under the 1940 Act.
    
     REVERSE REPURCHASE AGREEMENTS. The Fund may borrow funds for temporary or
emergency purposes by selling portfolio securities to financial institutions
such as banks and broker/dealers and agreeing to repurchase them at a mutually
specified date and price ("reverse repurchase agreements"). Reverse repurchase
agreements involve the risk that the market value of the securities sold by the
Fund may decline below the repurchase price. The Fund will pay interest on
amounts obtained pursuant to a reverse repurchase agreement. While reverse
repurchase agreements are outstanding, the Fund will maintain cash, U.S.
Government securities or other liquid high-grade securities designated on the
books of the Fund or the Fund's sub-custodian in an amount at least equal to the
market value of the securities, plus accrued interest, subject to the 
agreement.     

     RIGHTS AND WARRANTS.  As stated in its Prospectuses, the Fund may purchase
warrants, which are privileges issued by corporations enabling the owners to
subscribe to and purchase a specified number of shares of the corporation at a
specified price during a specified period of time.  Subscription rights normally
have a short life span to expiration.  The purchase of warrants involves the
risk that the Fund could lose the purchase value of a warrant if the right to
subscribe to additional shares is not exercised prior to the warrant's
expiration.  Also, the 

                                       11
<PAGE>
 
purchase of warrants involves the risk that the effective price paid for the
warrant added to the subscription price of the related security may exceed the
value of the subscribed security's market price such as when there is no
movement in the level of the underlying security.

     STOCK INDEX FUTURES, OPTIONS ON STOCK AND BOND INDICES AND OPTIONS ON STOCK
AND BOND INDEX FUTURES CONTRACTS.  The Fund may purchase and sell stock index
futures, options on stock and bond indices and options on stock index futures
contracts as a hedge against movements in the equity and bond markets.

     A stock index futures contract is an agreement in which one party agrees to
deliver to the other an amount of cash equal to a specific dollar amount times
the difference between the value of a specific stock index at the close of the
last trading day of the contract and the price at which the agreement is made.
No physical delivery of securities is made.

     Options on stock and bond indices are similar to options on specific
securities, described above, except that, rather than the right to take or make
delivery of the specific security at a specific price, an option on a stock or
bond index gives the holder the right to receive, upon exercise of the option,
an amount of cash if the closing level of that stock or bond index is greater
than, in the case of a call option, or less than, in the case of a put option,
the exercise price of the option.  This amount of cash is equal to such
difference between the closing price of the index and the exercise price of the
option expressed in dollars times a specified multiple.  The writer of the
option is obligated, in return for the premium received, to make delivery of
this amount.  Unlike options on specific securities, all settlements of options
on stock or bond indices are in cash, and gain or loss depends on general
movements in the stocks included in the index rather than price movements in
particular stocks.

     If the Advisor expects general stock or bond market prices to rise, it
might purchase a stock index futures contract, or a call option on that index,
as a hedge against an increase in prices of particular securities it ultimately
wants to buy.  If in fact the index does rise, the price of the particular
securities intended to be purchased may also increase, but that increase would
be offset in part by the increase in the value of the futures contract or index
option resulting from the increase in the index.  If, on the other hand, the
Advisor expects general stock or bond market prices to decline, it might sell a
futures contract, or purchase a put option, on the index.  If that index does in
fact decline, the value of some or all of the securities in the Fund's portfolio
may also be expected to decline, but that decrease would be offset in part by
the increase in the value of the Fund's position in such futures contract or put
option.

     The Fund may purchase and write call and put options on stock index futures
contracts and bond index futures contracts.  The Fund may use such options on
futures contracts in connection with its hedging strategies in lieu of
purchasing and selling the underlying futures or purchasing and writing options
directly on the underlying securities or indices.  For example, the Fund may
purchase put options or write call options on stock and bond index futures,
rather than selling futures contracts, in anticipation of a decline in general
stock or bond market prices or purchase call options or write put options on
stock or bond index futures, rather than purchasing such futures, to hedge
against possible increases in the price of securities which the Fund intends to
purchase.

     In connection with transactions in stock or bond index futures, stock or
bond index options and options on stock or bond index futures, the Fund will be
required to deposit as "initial margin" an amount of cash and short-term U.S.
Government securities equal to between 5% to 8% of the contract amount.
Thereafter, subsequent payments (referred to as "variation margin") are made to
and from the broker to reflect changes in the value of the option or futures
contract.  The Fund may not at any time commit more than 5% of its total assets
to initial margin deposits on futures contracts, index options and options on
futures contracts.

     SUPRANATIONAL BANK OBLIGATIONS.  Supranational banks are international
banking institutions designed or supported by national governments to promote
economic reconstruction, development or trade between nations (e.g., The World
Bank).  Obligations of supranational banks may be supported by appropriated but
unpaid commitments of their member countries and there is no assurance these
commitments will be undertaken or met in the future.

                                       12
<PAGE>
 
    
     U.S. GOVERNMENT OBLIGATIONS.  The Fund may purchase obligations issued or
guaranteed by the U.S. Government and U.S. Government agencies and
instrumentalities.  Obligations of certain agencies and instrumentalities of the
U.S. Government, such as those of the Government National Mortgage Association
("GNMA"), are supported by the full faith and credit of the U.S. Treasury.
Others, such as those of the Export-Import Bank of the United States, are
supported by the right of the issuer to borrow from the U.S. Treasury; and still
others, such as those of the Student Loan Marketing Association, are supported
only by the credit of the agency or instrumentality issuing the obligation.  No
assurance can be given that the U.S. Government would provide financial support
to U.S. government-sponsored instrumentalities if it is not obligated to do so
by law.  Examples of the types of U.S. Government obligations that may be
acquired by the Funds include U.S. Treasury Bills, Treasury Notes and Treasury
Bonds and the obligations of Federal Home Loan Banks, Federal Farm Credit Banks,
Federal Land Banks, the Federal Housing Administration, Farmers Home
Administration, Export-Import Bank of the United States, Small Business
Administration, FNMA, GNMA, General Services Administration, Student Loan
Marketing Association, Central Bank for Cooperatives, FHLMC, Federal
Intermediate Credit Banks and Maritime Administration.     

     VARIABLE AND FLOATING RATE INSTRUMENTS.  Debt instruments may be structured
to have variable or floating interest rates.  Variable and floating rate
obligations purchased by a Fund may have stated maturities in excess of a Fund's
maturity limitation if the Fund can demand payment of the principal of the
instrument at least once during such period on not more than thirty days' notice
(this demand feature is not required if the instrument is guaranteed by the U.S.
Government or an agency thereof).  These instruments may include variable amount
master demand notes that permit the indebtedness to vary in addition to
providing for periodic adjustments in the interest rates.  The Advisor will
consider the earning power, cash flows and other liquidity ratios of the issuers
and guarantors of such instruments and, if the instrument is subject to a demand
feature, will continuously monitor their financial ability to meet payment on
demand.  Where necessary to ensure that a variable or floating rate instrument
is equivalent to the quality standards applicable to the Fund, the issuer's
obligation to pay the principal of the instrument will be backed by an
unconditional bank letter or line of credit, guarantee or commitment to lend.

     In determining average weighted portfolio maturity of the Fund, an
instrument will usually be deemed to have a maturity equal to the longer of the
period remaining until the next interest rate adjustment or the time the Fund
involved can recover payment of principal as specified in the instrument.
Variable rate U.S. Government obligations held by the Fund, however, will be
deemed to have maturities equal to the period remaining until the next interest
rate adjustment.

     The absence of an active secondary market for certain variable and floating
rate notes could make it difficult to dispose of the instruments, and the Fund
could suffer a loss if the issuer defaulted or during periods that the Fund is
not entitled to exercise its demand rights.

     Variable and floating rate instruments held by the Fund will be subject to
the Fund's limitation on illiquid investments when the Fund may not demand
payment of the principal amount within seven days absent a reliable trading
market.

     WHEN-ISSUED PURCHASES AND FORWARD COMMITMENTS (DELAYED-DELIVERY
TRANSACTIONS).  When-issued purchases and forward commitments (delayed-delivery
transactions) are commitments by the Fund to purchase or sell particular
securities with payment and delivery to occur at a future date (perhaps one or
two months later).  These transactions permit the Fund to lock-in a price or
yield on a security, regardless of future changes in interest rates.

     When the Fund agrees to purchase securities on a when-issued or forward
commitment basis, the Fund will earmark cash or liquid portfolio securities
equal to the amount of the commitment.  Normally, the Fund will earmark
portfolio securities to satisfy a purchase commitment, and in such a case the
Fund may be required subsequently to earmark additional assets in order to
ensure that the value of the account remains equal to the amount of the Fund's
commitments.  It may be expected that the market value of the Fund's net assets
will fluctuate to a greater degree when it earmarks portfolio securities to
cover such purchase commitments than when it earmarks cash.  Because the Fund's
liquidity and ability to manage its portfolio might be affected when it earmarks
cash or 

                                       13
<PAGE>
 
portfolio securities to cover such purchase commitments, the Advisor expects
that its commitments to purchase when-issued securities and forward commitments
will not exceed 25% of the value of the Fund's total assets absent unusual
market conditions.

     The Fund will purchase securities on a when-issued or forward commitment
basis only with the intention of completing the transaction and actually
purchasing the securities.  If deemed advisable as a matter of investment
strategy, however, the Fund may dispose of or renegotiate a commitment after it
is entered into, and may sell securities it has committed to purchase before
those securities are delivered to the Fund on the settlement date.  In these
cases the Fund may realize a taxable capital gain or loss.

     When the Fund engages in when-issued and forward commitment transactions,
it relies on the other party to consummate the trade.  Failure of such party to
do so may result in the Fund's incurring a loss or missing an opportunity to
obtain a price considered to be advantageous.

     The market value of the securities underlying a when-issued purchase or a
forward commitment to purchase securities, and any subsequent fluctuations in
their market value, are taken into account when determining the market value of
the Fund starting on the day the Fund agrees to purchase the securities.  The
Fund does not earn interest on the securities it has committed to purchase until
they are paid for and delivered on the settlement date.

     YIELDS AND RATINGS.  The yields on certain obligations, including the money
market instruments in which the Fund may invest (such as commercial paper and
bank obligations), are dependent on a variety of factors, including general
money market conditions, conditions in the particular market for the obligation,
the financial condition of the issuer, the size of the offering, the maturity of
the obligation and the ratings of the issue.  The ratings of S&P, Moody's, Duff
& Phelps Credit Rating Co., Thomson Bank Watch, Inc., and other nationally
recognized statistical rating organizations ("NRSROs") represent their
respective opinions as to the quality of the obligations they undertake to rate.
Ratings, however, are general and are not absolute standards of quality.
Consequently, obligations with the same rating, maturity and interest rate may
have different market prices.

     OTHER.  Subsequent to its purchase by the Fund, a rated security may cease
to be rated or its rating may be reduced below the minimum rating required for
purchase by the Fund.  The Boards of Trustees will consider such an event in
determining whether the Fund involved should continue to hold the security in
accordance with the interests of the Fund and applicable regulations of the SEC.

                            INVESTMENT LIMITATIONS
                                        
     The Fund is subject to the investment limitations enumerated in this
section which may be changed with respect to the Fund only by a vote of the
holders of a majority of the Fund's outstanding shares (as defined under
"Miscellaneous Shareholder Approvals").

     The Fund may not:

     1.   Purchase securities of any one issuer (other than securities issued or
          guaranteed by the U.S. Government, its agencies or instrumentalities
          or certificates of deposit for any such securities) if more than 5% of
          the value of the Fund's total assets (taken at current value) would be
          invested in the securities of such issuer, or more than 10% of the
          issuer's outstanding voting securities would be owned by the Fund or
          the Trust, except that with respect to the Fund, up to 25% of the
          value of the Fund's total assets (taken at current value) may be
          invested without regard to these limitations so long as no more than
          25% of the value of the Fund's total assets are invested in the
          securities of any one issuer.  For purposes of this limitation, a
          security is considered to be issued by the entity (or entities) whose
          assets and revenues back the security.  A guarantee of a security is
          not deemed to be a security issued by the guarantor when the value of
          all securities issued and guaranteed by the guarantor, and owned by
          the Fund, does not exceed 10% of the value of the Fund's total assets;

                                       14
<PAGE>
 
    
     2.   Borrow money or issue senior securities except that the Fund may
          borrow from banks and enter into reverse repurchase agreements for
          temporary purposes in amounts up to one-third of the value of its
          total assets at the time of such borrowing; or mortgage, pledge or
          hypothecate any assets, except in connection with any such borrowing
          and then in amounts not in excess of one-third of the value of the
          Fund's total assets at the time of such borrowing.  The Fund will not
          purchase securities while its aggregate borrowings (including reverse
          repurchase agreements and borrowing from banks) in excess of 5% of its
          total assets are outstanding.  Securities held in escrow or separate
          accounts in connection with a Fund's investment practices are not
          deemed to be pledged for purposes of this limitation;     

     3.   Purchase any securities which would cause 25% or more of the value of
          the Fund's total assets at the time of purchase to be invested in the
          securities of one or more issuers conducting their principal business
          activities in the same industry, provided that (a) there is no
          limitation with respect to (i) instruments that are issued (as defined
          in investment limitation 1 above) or guaranteed by the United States,
          any state, territory or possession of the United States, the District
          of Columbia or any of their authorities, agencies, instrumentalities
          or political subdivisions, and (ii) repurchase agreements secured by
          the instruments described in clauses (i); (b) wholly-owned finance
          companies will be considered to be in the industries of their parents
          if their activities are primarily related to financing the activities
          of the parents; and (c) utilities will be divided according to their
          services, for example, gas, gas transmission, electric and gas,
          electric and telephone will each be considered a separate industry;

     4.   Purchase or sell real estate, except that the Fund may purchase
          securities of issuers which deal in real estate and may purchase
          securities which are secured by interests in real estate;

     5.   Acquire any other investment company or investment company security
          except in connection with a merger, consolidation, reorganization or
          acquisition of assets or where otherwise permitted by the 1940 Act;

     6.   Act as an underwriter of securities within the meaning of the
          Securities Act of 1933, as amended, except to the extent that the
          purchase of obligations directly from the issuer thereof, or the
          disposition of securities, in accordance with the Fund's investment
          objective, policies and limitations may be deemed to be underwriting;

     7.   Write or sell put options, call options, straddles, spreads, or any
          combination thereof except for transactions in options on securities,
          securities indices, futures contracts, options on futures contracts
          and transactions in securities on a when-issued or forward commitment
          basis, and except that the Fund may enter into forward currency
          contracts in accordance with its investment objectives and policies;

     8.   Purchase securities of companies for the purpose of exercising
          control;

     9.   Purchase securities on margin, make short sales of securities or
          maintain a short position, except that (a) this investment limitation
          shall not apply to the Fund's transactions in futures contracts and
          related options, the Fund's sale of securities short against the box
          or the Fund's transactions in securities on a when-issued or forward
          commitment basis, and (b) the Fund may obtain short-term credit as may
          be necessary for the clearance of purchases and sales of portfolio
          securities;

     10.  Purchase or sell commodity contracts, or invest in oil, gas or mineral
          exploration or development programs, except that the Fund may, to the
          extent appropriate to its investment policies, purchase publicly
          traded securities of companies engaging in whole or in part in such
          activities, may enter into futures contracts and related options, and
          may engage in transactions in securities on a when-issued or forward
          commitment basis, and except that the Fund may enter into forward
          currency contracts in accordance with its investment objectives and
          policies; or

                                       15
<PAGE>
 
     11.  Make loans, except that the Fund may purchase and hold debt
          instruments (whether such instruments are part of a public offering or
          privately negotiated), may enter into repurchase agreements and may
          lend portfolio securities in accordance with its investment objective
          and policies.

     If a percentage limitation is satisfied at the time of investment, a later
increase or decrease in such percentage resulting from a change in the value of
the Fund's investments will not constitute a violation of such limitation,
except that any borrowing by the Fund that exceeds the fundamental investment
limitations stated above must be reduced to meet such limitations within the
period required by the 1940 Act (currently three days).  Otherwise, the Fund may
continue to hold a security even though it causes the Fund to exceed a
percentage limitation because of fluctuation in the value of the Fund's assets.

     No officer, director or employee of the Advisor, Comerica Incorporated
("Comerica"), the Sub-Custodian, the Distributor, the Administrator or the
Transfer Agent currently receives any compensation from the Trust, Framlington
or the Company. As of September 30, 1998, the Trustees and officers of the
Trust, as a group, owned less than 1% of all classes of outstanding shares of
the Fund.     

    
     
     SHAREHOLDER AND TRUSTEE LIABILITY.  Under Massachusetts law, shareholders
of a business trust may, under certain circumstances, be held personally liable
for the obligations of the trust. However, the Trust's Declaration of Trust, as
amended, provides that shareholders shall not be subject to any personal
liability in connection with the assets of the Trust for the acts or obligations
of the Trust, and that every note, bond, contract, order or other undertaking
made by the Trust shall contain a provision to the effect that the shareholders
are not personally liable thereunder.  The Declaration of Trust, as amended,
provides for indemnification out of the trust property of any shareholder held
personally liable solely by reason of his or her being or having been a
shareholder and not because of his or her acts or omissions or some other
reason.  The Declaration of Trust, as amended, also 

                                       19
<PAGE>
 
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 shall
satisfy any judgment thereon. Thus, the risk of a shareholder's incurring
financial loss on account of shareholder liability is limited to circumstances
in which the Trust itself would be unable to meet its obligations.

     The Declaration of Trust, as amended, further provides that all persons
having any claim against the Trustees or the Trust shall look solely to the
trust property for payment; that no Trustee of the Trust shall be personally
liable for or on account of any contract, debt, tort, claim, damage, judgment or
decree arising out of or connected with the administration or preservation of
the trust property or the conduct of any business of the Trust; and that no
Trustee shall be personally liable to any person for any action or failure to
act except by reason of his own bad faith, willful misfeasance, gross negligence
or reckless disregard of his duties as a trustee.  With the exception stated,
the Declaration of Trust, as amended, provides that a Trustee is entitled to be
indemnified against all liabilities and expenses reasonably incurred by him in
connection with the defense or disposition of any proceeding in which he may be
involved or with which he may be threatened by reason of being or having been a
Trustee, and that the Trustees will indemnify officers, representatives and
employees of the Trust to the same extent that Trustees are entitled to
indemnification.

              INVESTMENT ADVISORY AND OTHER SERVICE ARRANGEMENTS

                                            
     INVESTMENT ADVISOR.  The Advisor of the Fund is Munder Capital Management,
a Delaware general partnership.  The Advisor replaced Woodbridge Capital
Management, Inc. ("Woodbridge") as investment advisor to the investment
portfolios of the Trust on January 31, 1995, upon the closing agreement (the
"Joint Venture Agreement") among MCM, Comerica, Woodbridge and WAM, pursuant to
which MCM contributed its investment advisory business and Comerica contributed
the investment advisor business of its indirect subsidiaries, Woodbridge and
World Asset Management, to the Advisor.  The general partners of the Advisor are
WAM, WAM II, MCM and Munder Group LLC.  WAM and WAM II are wholly-owned
subsidiaries of Comerica Bank  Ann Arbor, which in turn is a wholly-owned
subsidiary of Comerica Incorporated, a publicly-held bank holding company.

     The Fund has entered into new Investment Advisory Agreement (the "Advisory
Agreement"), dated July 2, 1998, with the Advisor pursuant to terms of an
Exemptive Order (the "Order") granted by the Securities and Exchange Commission.
Under the terms of the Order, the Advisory Agreement must be approved by the
shareholders within one hundred and fifty (150) days but no later than November
30, 1998.  The Fund will call a special meeting of the shareholders to approve
the Advisory Agreement.  Until shareholder approval, the fees paid to the
Advisor will be paid into an escrow account.  If the Advisory Agreement is not
approved by the shareholders, the Board of Trustees will consider appropriate
action.  Under the terms of the Advisory Agreement, the Advisor furnishes
continuing investment supervision to the Fund and is responsible for the
management of the Fund.  The responsibility for making decisions to buy, sell or
hold a particular security rests with the Advisor, subject to review by the
Trust's Boards of Trustees.
     

     Once the Advisory Agreement is approved by shareholders, it will continue
in effect for a period of two years from their effective dates. If not sooner
terminated, the Advisory Agreement will continue in effect for successive one
year periods thereafter, provided that each continuance is specifically approved
annually by (a) the vote of a majority of the Board of Trustees who are not
parties to the Advisory Agreement or interested persons (as defined in the 1940
Act), cast in person at a meeting called for the purpose of voting on approval,
and (b) either (i) the vote of a majority of the outstanding voting securities
of the Fund, or (ii) the vote of a majority of the Board of Trustees. The
Advisory Agreement is terminable by vote of the Board of Trustees, or by the
holders of a majority of the outstanding voting securities of the Fund, at any
time without penalty, on 60 days' written notice to the Advisor. The Advisor may
also terminate its advisory relationship with the Fund without penalty on 90
days' written notice to the Trust. The Advisory Agreement terminates
automatically in the event of its assignment (as defined in the 1940 Act).

     For the advisory services provided and expenses assumed with regard to the
Fund, the Advisor has agreed to a fee from the Fund, computed daily and payable
monthly, at an annual rate of 0.75% of the average daily net assets of the Fund.

                                       20

     For the fiscal year ended June 30, 1998, the Advisor received fees after
waivers, if any, of $1,451,332 for the Fund.
     

     For the fiscal year ended June 30, 1997, the Advisor received fees after
waivers, if any, of $2,040,543 for the Fund.

     DISTRIBUTION AGREEMENTS.  The Trust has entered into a distribution
agreement, under which the Distributor, as agent, sells shares of the Fund on a
continuous basis.  The Distributor has agreed to use appropriate efforts to
solicit orders for the purchase of shares of the Fund, although it is not
obligated to sell any particular amount of shares.  The Distributor pays the
cost of printing and distributing prospectuses to persons who are not holders of
shares of the Fund (excluding preparation and printing expenses necessary for
the continued registration of the shares) and of printing and distributing all
sales literature.  The Distributor's principal offices are located at 60 State
Street, Boston, Massachusetts 02109.

     DISTRIBUTION SERVICES ARRANGEMENTS - CLASS A, CLASS B AND CLASS C SHARES.
The Fund has adopted a Service and Distribution Plan with respect to its Class A
Shares pursuant to which it uses its assets to finance activities relating to
the provision of certain shareholder services.  Under the Service and
Distribution Plan for Class A Shares, the Distributor is paid an annual service
fee at the rate of up to 0.25% of the value of average daily net assets of the
Class A Shares of the Fund.  The Fund has also adopted a Service and
Distribution Plan with respect to its Class B and Class C Shares, pursuant to
which it uses its assets to finance activities relating to the distribution of
its shares to investors and provision of certain shareholder services.  Under
the Service and Distribution Plans for Class B and Class C Shares, the
Distributor is paid an annual service fee of up to 0.25% of the value of average
daily net assets of the Class B and Class C Shares of the Fund and an annual
distribution fee at the rate of up to 0.75% of the value of average daily net
assets of the Class B and Class C Shares of the Fund.

     Under the terms of the Service and Distribution Plans (collectively, the
"Plans"), each Plan continues from year to year, provided such continuance is
approved annually by vote of the Board of Trustees, including a majority of the
Board of Trustees who are not interested persons of the Trust and who have no
direct or indirect financial interest in the operation of that Plan (the "Non-
Interested Plan Trustees").  The Plans may not be amended to increase the amount
to be spent for the services provided by the Distributor without shareholder
approval, and all amendments of the Plans also must be approved by the Trustees
in the manner described above.  Each Plan may be terminated at any time, without
penalty, by vote of a majority of the Non-Interested Plan Trustees or by a vote
of a majority of the outstanding voting securities of the relevant class of the
Fund (as defined in the 1940 Act) on not more than 30 days' written notice to
any other party to the Plan.  Pursuant to each Plan, the Distributor will
provide the Board of Trustees periodic reports of amounts expended under the
Plan and the purpose for which such expenditures were made.

     The Trustees have determined that the Plans will benefit the Trust and
their respective shareholders by (i) providing an incentive for broker or bank
personnel to provide continuous shareholder servicing after the time of sale;
(ii) retention of existing accounts; (iii) facilitating portfolio management
flexibility through continued cash flow into the Funds; and (iv) maintaining a
competitive sales structure in the mutual fund industry.

     With respect to Class B and Class C Shares of the Fund, the Distributor
expects to pay sales commissions to dealers authorized to sell the Fund's Class
B and Class C Shares at the time of sale.  The Distributor will use its own
funds (which may be borrowed) to pay such commissions pending reimbursement by
the relevant Service and Distribution Plan.  In addition, the Advisor may use
its own resources to make payments to the Distributor or dealers authorized to
sell the Fund's shares to support their sales efforts.

     SHAREHOLDER SERVICING ARRANGEMENTS - CLASS K SHARES.  As stated in the
Fund's Prospectus, Class K Shares are sold to investors through institutions
which enter into Shareholder Servicing Agreements with the Trust to provide
support services to their Customers who beneficially own Class K Shares in
consideration of the Fund's payment of not more than 0.25% (on an annualized
basis) of the average daily net asset value of the Class K Shares beneficially
owned by the Customers.

     Services provided by institutions under their service agreements may
include: (i) aggregating and processing purchase and redemption requests for
Class K Shares from Customers and placing net purchase and redemption orders
with the Distributor; (ii) providing Customers with a service that invests the
assets of their accounts in Class K Shares pursuant to specific or pre-
authorized instructions; (iii) processing dividend payments on

                                       22
<PAGE>
 
behalf of Customers; (iv) providing information periodically to Customers
showing their positions in Class K Shares; (v) arranging for bank wires; (vi)
responding to Customer inquiries relating to the services performed by the
institutions; (vii) providing subaccounting with respect to Class K Shares
beneficially owned by Customers or the information necessary for subaccounting;
(viii) if required by law, forwarding shareholder communications from the Trust
(such as proxies, shareholder reports, annual and semi-annual financial
statements and dividend, distribution and tax notices) to Customers; (ix)
forwarding to Customers proxy statements and proxies containing any proposals
regarding the Trust's arrangements with institutions; and (x) providing such
other similar services as the Trust, may reasonably request to the extent the
institutions are permitted to do so under applicable statutes, rules and
regulations.

     Pursuant to the Trust's agreements with such institutions, the Board of
Trustees will review, at least quarterly, a written report of the amounts
expended under Trust's agreements with Institutions and the purposes for which
the expenditures were made.  In addition, the arrangements with Institutions
must be approved annually by a majority of the Board of Trustees, including a
majority of the Trustees who are not "interested persons" as defined in the 1940
Act, and have no direct or indirect financial interest in such arrangements.

     The Board of Trustees have approved the arrangements with Institutions
based on information provided by the service contractors that there is a
reasonable likelihood that the arrangements will benefit the Fund and their
shareholders by affording the Fund greater flexibility in connection with the
servicing of the accounts of the beneficial owners of their shares in an
efficient manner.

     ADMINISTRATION AGREEMENT.  State Street Bank and Trust Company ("State
Street"), whose principal business address is 225 Franklin Street, Boston,
Massachusetts, 02110, serves as administrator for the Trust pursuant to an
administration agreement (the "Administration Agreement").  State Street has
agreed to maintain office facilities for the Trust; oversee the computation of
the Fund's net asset value, net income and realized capital gains, if any;
furnish statistical and research data, clerical services, and stationery and
office supplies; prepare and file various reports with the appropriate
regulatory agencies; and prepare various materials required by the SEC.  State
Street may enter into an agreement with one or more third parties pursuant to
which such third parties will provide administrative services on behalf of the
Fund.

     The Administration Agreement provides that the Administrator performing
services thereunder shall not be liable under the Agreement except for its bad
faith, negligence or willful misconduct in the performance of its duties and
obligations thereunder.

    
     For the period November 1, 1997 through June 30, 1998, the accrued
administration fees of State Street were $59,215 for the Fund.
     

     Prior to November 1, 1997, First Data Investor Services Group, Inc.
("Investor Services Group") located at 53 State Street, Boston, Massachusetts
02109 served as administrator to the Fund.

     For the period of July 1, 1997 through October 31, 1997, the accrued
administration fees of Investor Services Group were $42,453 for the Fund.

     For the fiscal year ended June 30, 1997, the accrued administration fees of
Investor Services Group were $307,521 for the Fund.

     For the fiscal year ended June 30, 1996, the accrued administration fees of
Investor Services Group were $322,120 for the Fund.

     CUSTODIAN, SUB-CUSTODIAN AND TRANSFER AGENCY AGREEMENTS. Comerica Bank (the
"Custodian"), whose principal business address is One Detroit Center, 500
Woodward Avenue, Detroit, MI 48226, is the custodian of the Fund pursuant to a
custodian agreement (a "Custody Agreement") with the Trust. The Custodian
receives no compensation for such services. State Street serves as the sub-
custodian to the Fund pursuant to a sub-custodian agreement (a "Sub-Custodian
Contract") among the Trust, Comerica Bank and State Street. State Street is also
the

                                       23
<PAGE>
 
sub-custodian with respect to the custody of foreign securities held by the
Fund. State Street has in turn entered into additional agreements with financial
institutions and depositaries located in foreign countries with respect to the
custody of such securities. Under the Sub-Custodian Contract, the Sub-Custodian
(i) maintains a separate account in the name of the Fund, (ii) holds and
transfers portfolio securities on account of the Fund, (iii) accepts receipts
and makes disbursements of money on behalf of the Fund, (iv) collects and
receives all income and other payments and distributions on account of the
Fund's securities and (v) makes periodic reports to the Board of Trustees
concerning the Fund's operations.

     Prior to November 1, 1997, the Custodian was compensated for its services
as custodian.  For the period July 1, 1997 to October 31, 1997 the Custodian
earned $317,499.

     Investor Services Group serves as the transfer and dividend disbursing
agent for the Fund pursuant to a transfer agency agreement (the "Transfer Agency
Agreement") with the Trust, under which Investor Services Group (i) issues and
redeems shares of the Fund, (ii) addresses and mails all communications by the
Fund to its record owners, including reports to shareholders, dividend and
distribution notices and proxy materials for its meetings of shareholders, (iii)
maintains shareholder accounts, (iv) responds to correspondence by shareholders
of the Fund and (v) makes periodic reports to the Board of Trustees concerning
the operations of the Fund.

     COMERICA.  As stated in the Fund's Class K Shares Prospectus, Class K
Shares of the Fund are sold to customers of banks and other institutions.  Such
banks and institutions may include Comerica Incorporated (a publicly-held bank
holding company), its affiliates and subsidiaries ("Comerica") and other
institutions that have entered into agreements with the Trust providing for
shareholder services for their customers.

     Banking laws and regulations currently prohibit a bank holding company
registered under the Federal Bank Holding Company Act of 1956 or any bank or
non-bank affiliate thereof from sponsoring, organizing, controlling or
distributing the shares of a registered, open-end investment company
continuously engaged in the issuance of its shares, and prohibit banks generally
from underwriting securities, but such banking laws and regulations do not
prohibit such a holding company or affiliate or banks generally from acting as
investment advisor, administrator, transfer agent or custodian to such an
investment company, or from purchasing shares of such a company as agent for and
upon the order of customers.  The Advisor and the Custodian are subject to such
banking laws and regulations.

     The Advisor and the Custodian believe they may perform the services for the
Trust contemplated by its respective agreements with each of them without
violation of applicable banking laws and regulations.  It should be noted,
however, that there have been no cases deciding whether bank and non-bank
subsidiaries of a registered bank holding company may perform services
comparable to those that are to be performed by these companies, and future
changes in either Federal or state statutes and regulations relating to
permissible activities of banks and their subsidiaries or affiliates, as well as
future judicial or administrative decisions or interpretations of current and
future statutes and regulations, could prevent these companies from continuing
to perform certain services for the Fund.

     Should future legislative, judicial or administrative action prohibit or
restrict the activities of such companies in connection with the provision of
services on behalf of the Trust, the Trust might be required to alter materially
or discontinue the arrangements with the institutions and change the method of
operations.  It is not anticipated, however, that any change in the Fund's
method of operations would affect the net asset value per share of the Fund or
result in a financial loss to any shareholder of the Fund.

     It should be noted that future changes in either Federal or state statutes
and regulations relating to permissible activities of banks and their
subsidiaries or affiliates, as well as future judicial or administrative
decisions or interpretations of current and future statutes and regulations,
could prevent Comerica and certain other institutions from continuing to perform
certain services for Class K shares of the Fund.

     Should future legislative, judicial or administrative action prohibit or
restrict the activities of Comerica and/or other institutions in connection with
the provision of services on behalf of Class K shares of the Fund, the Trust
might be required to alter materially or discontinue the arrangements with the
institutions and change the 

                                       24
<PAGE>
 
method of operations with respect to Comerica and certain other institutions. It
is not anticipated, however, that any change in the Fund's method of operations
would affect the net asset value per share of the Fund's or result in a
financial loss to any holder of Class K shares of the Fund.

                            PORTFOLIO TRANSACTIONS

     Subject to the general supervision of the Board Members, the Advisor makes
decisions with respect to and places orders for all purchases and sales of
portfolio securities for the Fund.

     Transactions on U.S. stock exchanges involve the payment of negotiated
brokerage commissions.  On exchanges on which commissions are negotiated, the
cost of transactions may vary among different brokers.  Transactions on foreign
stock exchanges involve payment for brokerage commissions which are generally
fixed.
    
     For the fiscal year ended June 30, 1998, the Funds paid brokerage
commission totaling $170,477 for the Fund.

     For the fiscal year ended June 30, 1997, the Funds paid brokerage
commissions totaling $506,861 for the Fund.

     For the fiscal year ended June 30, 1996, the Funds paid brokerage
commissions totaling $474,252 for the Fund.
     
     
     Over-the-counter issues, including corporate debt and government
securities, are normally traded on a "net" basis (i.e., without commission)
through dealers, or otherwise involve transactions directly with the issuer of
an instrument.  With respect to over-the-counter transactions, the Advisor will
normally deal directly with dealers who make a market in the instruments
involved except in those circumstances where more favorable prices and execution
are available elsewhere.  The cost of foreign and domestic securities purchased
from underwriters includes an underwriting commission or concession, and the
prices at which securities are purchased from and sold to dealers include a
dealer's mark-up or mark-down.

     The Fund may participate, if and when practicable, in bidding for the
purchase of portfolio securities directly from an issuer in order to take
advantage of the lower purchase price available to members of a bidding group.
The Fund will engage in this practice, however, only when the Advisor believes
such practice to be in the Fund's interests.

     The portfolio turnover rate of the Fund is calculated by dividing the
lesser of the Fund's annual sales or purchases of portfolio securities
(exclusive of purchases or sales of securities whose maturities at the time of
acquisition were one year or less for the Fund) by the monthly average value of
the securities held by the Fund during the year.  The Fund may engage in short-
term trading to achieve its investment objective.  Portfolio turnover may vary
greatly from year to year as well as within a particular year.

    
     The Fund's portfolio turnover rate is included in the prospectuses under
the section entitled "Financial Highlights."  For the fiscal year ended June 30,
1998, the portfolio turnover rate for the Fund was 76%.
     

     In its Advisory Agreement, the Advisor agrees to select broker-dealers in
accordance with guidelines established by the Board of Trustees from time to
time and in accordance with applicable law. In assessing the terms available for
any transaction, the Advisor shall consider all factors it deems relevant,
including the breadth of the market in the security, the price of the security,
the financial condition and execution capability of the broker-dealer, and the
reasonableness of the commission, if any, both for the specific transaction and
on a continuing basis. In addition, the Advisory Agreement authorizes the
Advisor, subject to the prior approval of the Board of Trustees, to cause the
Fund to pay a broker-dealer which furnishes brokerage and research services a
higher commission than that which might be charged by another broker-dealer for
effecting the same transaction, provided that the Advisor determines in good
faith that such commission is reasonable in relation to the value of the
brokerage and research services provided by such broker-dealer, viewed in terms
of either the particular transaction or the overall

                                       25
<PAGE>
 
responsibilities of the Advisor to the Fund.  Such brokerage and research
services might consist of reports and statistics on specific companies or
industries, general summaries of groups of bonds and their comparative earnings
and yields, or broad overviews of the securities markets and the economy.

     Supplementary research information so received is in addition to, and not
in lieu of, services required to be performed by the Advisor and does not reduce
the advisory fees payable to the Advisor by the Fund.  It is possible that
certain of the supplementary research or other services received will primarily
benefit one or more other investment companies or other accounts for which
investment discretion is exercised.  Conversely, the Fund may be the primary
beneficiary of the research or services received as a result of portfolio
transactions effected for such other account or investment company.

     Portfolio securities will not be purchased from or sold to the Advisor,
Distributor or any affiliated person (as defined in the 1940 Act) of the
foregoing entities except to the extent permitted by SEC exemptive order or by
applicable law.

     Investment decisions for the Fund and for other investment accounts managed
by the Advisor are made independently of each other in the light of differing
conditions.  However, the same investment decision may be made for two or more
of such accounts.  In such cases, simultaneous transactions are inevitable.
Purchases or sales are then averaged as to price and allocated as to amount in a
manner deemed equitable to each such account.  While in some cases this practice
could have a detrimental effect on the price or value of the security as far as
the Fund is concerned, in other cases it is believed to be beneficial to the
Fund.  To the extent permitted by law, the Advisor may aggregate the securities
to be sold or purchased for the Fund with those to be sold or purchased for
other investment companies or accounts in executing transactions.

     The Fund will not purchase securities during the existence of any
underwriting or selling group relating to such securities of which the Advisor
or any affiliated person (as defined in the 1940 Act) thereof is a member except
pursuant to procedures adopted by the Trust's Board of Trustees in accordance
with Rule 10f-3 under the 1940 Act.
    
     The Trust is required to identify the securities of their regular brokers
or dealers (as defined in Rule 10b-1 under the 1940) Act or their parent
companies held by them as of the close of their most recent fiscal year and
state the value of such holdings.  As of June 30, 1998, the Fund held securities
of Bankamerica Corp valued at $4,270,013 and Chase Manhattan valued at 
$3,231,400.     

     Except as noted in the Prospectuses and this Statement of Additional
Information the Fund's service contractors bear all expenses in connection with
the performance of their services and the Fund bears the expenses incurred in
its operations.  These expenses include, but are not limited to, fees paid to
the Advisor, Administrator, Custodian, Sub-Custodian and Transfer Agent; fees
and expenses of officers and Board of Trustees; taxes; interest; legal and
auditing fees; brokerage fees and commissions; certain fees and expenses in
registering and qualifying the Fund and its shares for distribution under
Federal and state securities laws; expenses of preparing prospectuses and the
statement of additional information and of printing and distributing
prospectuses and statement of additional information to existing shareholders;
the expense of reports to shareholders, shareholders' meetings and proxy
solicitations; fidelity bond and directors' and officers' liability insurance
premiums; the expense of using independent pricing services; and other expenses
which are not assumed by the Administrator.  Any general expenses of the Trust
that are not readily identifiable as belonging to a particular investment
portfolio of the Trust are allocated among all investment portfolios of the
Trust by or under the direction of the Board of Trustees and in a manner that
the Board of Trustees determines to be fair and equitable.  The Advisor,
Administrator, Custodian, Sub-Custodian and Transfer Agent may voluntarily waive
all or a portion of their respective fees from time to time.

    
                ADDITIONAL PURCHASE AND REDEMPTION INFORMATION
     

     PURCHASES.  As described in the Prospectuses, shares of the Fund may be
purchased in a number of different ways.  Such alternative sales arrangements
permit an investor to choose the method of purchasing shares that is more
beneficial depending on the amount of the purchase, the length of time the
investor expects to hold 

                                       26
<PAGE>
 
shares and other relevant circumstances. An investor may place orders directly
through the Transfer Agent or the Distributor or through arrangements with
his/her authorized broker.

     RETIREMENT PLANS.  Shares of the Fund may be purchased in connection with
various types of tax deferred retirement plans, including individual retirement
accounts ("IRAs"), qualified plans, deferred compensation for public schools and
charitable organizations (403(b) plans) and simplified employee pension IRAs.
An individual or organization considering the establishment of a retirement plan
should consult with an attorney and/or an accountant with respect to the terms
and tax aspects of the plan.  A $10.00 annual custodial fee is also charged on
IRAs.  This custodial fee is due by December 15 of each year and may be paid by
check or shares liquidated from a shareholder's account.

     REDEMPTIONS.  As described in the Fund's Prospectuses, shares of the Fund
may be redeemed in a number of different ways:

          .  By Mail
          .  By Telephone
          .  Automatic Withdrawal Plan

The redemption price for Fund shares is the net asset value next determined
after receipt of the redemption request in proper order.  The redemption
proceeds will be reduced by the amount of any applicable contingent deferred
sales charge ("CDSC").

     CONTINGENT DEFERRED SALES CHARGE - CLASS B SHARES.  Class B Shares redeemed
within six years of purchase are subject to a CDSC.  The CDSC is based on the
original net asset value at the time of investment or the net asset value at the
time of redemption, whichever is lower.

     The CDSC Schedule for Class B Shares of the Fund purchased before June 27,
1995 is set forth below.  The Prospectuses describe the CDSC Schedule for Class
B Shares of the Fund purchased after June 27, 1995.

     CDSC WAIVERS - CLASS B SHARES OF THE TRUST FUNDS PURCHASED ON OR BEFORE
JUNE 27, 1995.  The CDSC will be waived with respect to Class B Shares of the
Trust Funds purchased on or before June 27, 1995 in the following circumstances:

     (1)  total or partial redemptions made within one year following the death
          or disability of a shareholder or registered joint owner;

     (2)  minimum required distributions made in connection with an IRA or other
          retirement plan following attainment of age 59 1/2; and

     (3)  redemptions pursuant to the Fund's right to liquidate a shareholder's
          account involuntarily.

     CONTINGENT DEFERRED SALES CHARGE - CLASS A AND CLASS C SHARES.  The
Prospectuses describe the CDSC for Class A or C Shares of the Fund purchased
after June 27, 1995.

                                       27
<PAGE>
 
     Class A Shares of the Trust Funds purchased on or before June 27, 1995
without a sales charge by reason of a purchase of $500,000 or more are subject
to a CDSC of 1.00% of the lower of the original purchase price or the net asset
value at the time of redemption if such shares are redeemed within two years of
the date of purchase.  Class A Shares of the Trust Funds purchased on or before
June 27, 1995 that are redeemed will not be subject to the CDSC to the extent
that the value of such shares represents: (1) reinvestment of dividends or other
distributions; (2) Class A Shares redeemed more than two years after their
purchase; (3) a minimum required distribution made in connection with IRA or
other retirement plans following attainment of age 59 1/2; or (4) total or
partial redemptions made within one year following the death or disability of a
shareholder or registered joint owner.

     No CDSC is imposed to the extent that the current net asset value of the
shares redeemed does not exceed (a) the current net asset value of shares
purchased through reinvestment of dividends or capital gain distributions plus
(b) the current net asset value of shares purchased more than one year prior to
the redemption, plus (c) increases in the net asset value of the shareholder's
shares above the purchase payments made during the preceding one year.

     The holding period of Class A or Class C Shares of a Fund acquired through
an exchange of the corresponding class of shares of the Munder Money Market Fund
(which are available only by exchange of Class A or Class C Shares of the Fund,
as the case may be) and The Munder Funds, Inc. (the "Company") Funds and the
non-money market funds of the Trust will be calculated from the date that the
Class A or Class C Shares of the Fund were initially purchased.

     In determining whether a CDSC is applicable to a redemption, the
calculation will be made in a manner that results in the lowest possible rate.
It will be assumed that the redemption is made first of amounts representing all
Class A Shares on which a front-end sales charge has been assessed; then of
shares acquired pursuant to the reinvestment of dividends and distributions; and
then of amounts representing the cost of shares purchased one year or more prior
to the redemption.

    
     OTHER REDEMPTION INFORMATION.  Redemption proceeds are normally paid in
cash; however, the Fund may pay the redemption price in whole or part by a
distribution in kind of securities from the portfolio of the Fund, in lieu of
cash, in conformity with applicable rules of the SEC.  If shares are redeemed in
kind, the redeeming shareholder might incur transaction costs in converting the
assets into cash.  The Fund is obligated to redeem shares solely in cash up to
the lesser of $250,000 or 1% of its net assets during any 90-day period for any
one shareholder.
     

     The Fund reserves the right to suspend or postpone redemptions during any
period when: (i) trading on the New York Stock Exchange (the "NYSE") is
restricted by applicable rules and regulations of the SEC; (ii) the NYSE is
closed for other than customary weekend and holiday closings; (iii) the SEC has
by order permitted such suspension or postponement for the protection of the
shareholders; or (iv) an emergency, as determined by the SEC, exists, making
disposal of portfolio securities or valuation of net assets of the Fund not
reasonably practicable.

     The Fund may involuntarily redeem an investor's shares if the net asset
value of such shares is less than $250; provided that involuntary redemptions
will not result from fluctuations in the value of an investor's shares. A notice
of redemption, sent by first-class mail to the investor's address of record,
will fix a date not less than 30 days after the mailing date, and shares will be
redeemed at the net asset value at the close of business on that date unless
sufficient additional shares are purchased to bring the aggregate account value
up to $250 or more. A check for the redemption proceeds payable to the investor
will be mailed to the investor at the address of record.

     EXCHANGES.  In addition to the method of exchanging shares described in the
Fund's Prospectuses, a shareholder exchanging at least $1,000 of shares (for
which certificates have not been issued) and who has authorized expedited
exchanges on the application form filed with the Transfer Agent may exchange
shares by telephoning the Fund at (800) 438-5789.  Telephone exchange
instructions must be received by the Transfer Agent by 4:00 p.m., Eastern time.
The Fund, Distributor and Transfer Agent reserve the right at any time to
suspend or terminate the expedited exchange procedure or to impose a fee for
this service.  During periods of unusual economic or market changes,
shareholders may experience difficulties or delays in effecting telephone
exchanges.  Neither the Fund nor the Transfer Agent will be responsible for any
loss, damages, expense or cost arising out of any telephone

                                       28
<PAGE>
 
exchanges effected upon instructions believed by them to be genuine. The
Transfer Agent has instituted procedures that it believes are reasonably
designed to insure that exchange instructions communicated by telephone are
genuine, and could be liable for losses caused by unauthorized or fraudulent
instructions in the absence of such procedures. The procedures currently include
a recorded verification of the shareholder's name, social security number and
account number, followed by the mailing of a statement confirming the
transaction, which is sent to the address of record.

                             NET ASSET VALUE
                                        
     In determining the approximate market value of portfolio investments, the
Trust may employ outside organizations, which may use matrix or formula methods
that take into consideration market indices, matrices, yield curves and other
specific adjustments.  This may result in the securities being valued at a price
different from the price that would have been determined had the matrix or
formula methods not been used.  All cash, receivables and current payables are
carried on the Trust's books at their face value.  Other assets, if any, are
valued at fair value as determined in good faith under the supervision of the
Board Members.

IN-KIND PURCHASES

     Payment for shares may, in the discretion of the Advisor, be made in the
form of securities that are permissible investments for the Fund as described in
the Prospectuses.  For further information about this form of payment please
contact the Transfer Agent.  In connection with an in-kind securities payment,
the Fund will require, among other things, that the securities (a) meet the
investment objectives and policies of the Fund; (b) are acquired for investment
and not for resale; (c) are liquid securities that are not restricted as to
transfer either by law or liquidity of markets; (d) have a value that is readily
ascertainable by a listing on a nationally recognized securities exchange; and
(e) are valued on the day of purchase in accordance with the pricing methods
used by the Fund and that the Fund receive satisfactory assurances that (i) it
will have good and marketable title to the securities received by it; (ii) that
the securities are in proper form for transfer to the Fund; and (iii) adequate
information will be provided concerning the basis and other tax matters relating
to the securities.

                            PERFORMANCE INFORMATION

     TOTAL RETURN.  The Fund, in advertising its "average annual total return"
computes such return by determining the average annual compounded rate of return
during specified periods that equates the initial amount invested to the ending
redeemable value of such investment according to the following formula:

                              P (1 + T)/n/ = ERV
Where:
     P = hypothetical initial payment of $1,000;
     T = average annual total return;
     n = period covered by the computation, expressed in years;
     ERV = ending redeemable value of a hypothetical $1,000 payment made at the
     beginning of the 1, 5 or 10 year (or other) periods at the end of the
     applicable period (or a fractional portion thereof).

     The Fund, in advertising its "aggregate total return" computes such returns
by determining the aggregate compounded rates of return during specified periods
that likewise equate the initial amount invested to the ending redeemable value
of such investment.  The formula for calculating aggregate total return is as
follows:

                                   (ERV) - 1
                                   -----    
                          Aggregate Total Return = P

     The calculations are made assuming that (1) all dividends and capital gain
distributions are reinvested on the reinvestment dates at the price per share
existing on the reinvestment date, (2) all recurring fees charged to all
shareholder accounts are included, and (3) for any account fees that vary with
the size of the account, a mean (or

                                       29
<PAGE>
 
median) account size in the Fund during the periods is reflected. The ending
redeemable value (variable "ERV" in the formula) is determined by assuming
complete redemption of the hypothetical investment after deduction of all non-
recurring charges at the end of the measuring period. The Fund's average annual
total return and load adjusted aggregate total return quotations for Class A
Shares will reflect the deduction of the maximum sales charge charged in
connection with the purchase of such shares currently 5.50% of the per share
offering price for Class A Shares of the Fund; and the Fund's load adjusted
average annual total return and load adjusted aggregate total return quotations
for Class B Shares will reflect any applicable CDSC; provided that the Fund may
also advertise total return data without reflecting any applicable CDSC sales
charge imposed on the purchase of Class A Shares or Class B Shares in accordance
with the views of the SEC. Quotations which do not reflect the sales charge
will, of course, be higher than quotations which do.

     Based on the foregoing calculation, set forth below are the average annual
total return figures for the Class A, B, C, K and Y Shares of the Fund for the
12 month and 5 year periods ended June 30, 1998 and since commencement of
operations.

     The performance of any investment is generally a function of portfolio
quality and maturity, type of investment and operating expenses.

     From time to time, in advertisements or in reports to shareholders, the
Fund's total returns may be quoted and compared to those of other mutual funds
with similar investment objectives and to stock or other relevant indices. For
example, a Fund's yield may be compared to the IBC/Donoghue's Money Fund
Average, which is an average compiled by Donoghue's MONEY FUND REPORT of
Holliston, MA 01746, a widely recognized independent publication that monitors
the performance of money market funds, or to the data prepared by Lipper

                                     TAXES

    
     The following summarizes certain additional federal and state income tax
considerations generally affecting the Fund and its shareholders that are not
described in the Fund's Prospectuses.  No attempt is made to present a detailed
explanation of the tax treatment of the Fund or its shareholders, and the
discussion here and in the applicable Prospectus is not intended as a substitute
for careful tax planning.  This discussion is based upon present provisions of
the Internal Revenue Code, as amended ("Internal Revenue Code"), the regulations
promulgated thereunder, and judicial and administrative ruling authorities, all
of which are subject to change, which change may be retroactive.  Prospective
investors should consult their own tax advisors with regard to the federal tax
     

                                       30
<PAGE>
 
consequences of the purchase, ownership and disposition of Fund shares, as well
as the tax consequences arising under the laws of any state, foreign country, or
other taxing jurisdiction.

    
     GENERAL.  The Fund intends to elect and qualify to be taxed separately as a
regulated investment company under the Internal Revenue Code.  As a regulated
investment company, the Fund generally is exempt from federal income tax on its
net investment income and realized capital gains which it distributes to
shareholders, provided that it distributes an amount equal to the sum of (a) at
least 90% of its investment company taxable income (net investment income and
the excess of net short-term capital gain over net long-term capital loss), if
any, for the year and (b) at least 90% of its net tax-exempt interest income, if
any, for the year (the "Distribution Requirement") and satisfies certain other
requirements of the Internal Revenue Code that are described below.
Distributions of investment company taxable income and net tax-exempt interest
income made during the taxable year or, under specified circumstances, within
twelve months after the close of the taxable year will satisfy the Distribution
Requirement.
     

     In addition to satisfaction of the Distribution Requirement, the Fund must
derive with respect to a taxable year at least 90% of its gross income from
dividends, interest, certain payments with respect to securities loans and gains
from the sale or other disposition of stock or securities or foreign currencies,
or from other income derived with respect to its business of investing in such
stock, securities, or currencies (the "Income Requirement").  Interest
(including original issue discount and "accrued market discount") received by
the Fund at maturity or on disposition of a security held for less than three
months will not be treated (in contrast to other income which is attributable to
realized market appreciation) as gross income from the sale or other disposition
of securities held for less than three months for this purpose.

     In addition to the foregoing requirements, at the close of each quarter of
its taxable year, at least 50% of the value of the Fund's assets must consist of
cash and cash items, U.S. Government securities, securities of other regulated
investment companies, and securities of other issuers (as to which the Fund has
not invested more than 5% of the value of its total assets in securities of such
issuer and as to which the Fund does not hold more than 10% of the outstanding
voting securities of such issuer) and no more than 25% of the value of the
Fund's total assets may be invested in the securities of any one issuer (other
than U.S. Government securities and securities of other regulated investment
companies), or in two or more issuers which the Fund controls and which are
engaged in the same or similar trades or businesses.

     Distributions of net investment income received by the Fund from
investments in debt securities and any net realized short-term capital gains
distributed by the Fund will be taxable to shareholders as ordinary income and
will not be eligible for the dividends received deduction for corporations.

     The Fund intends to distribute to shareholders any excess of net long-term
capital gain over net short-term capital loss ("net capital gain") for each
taxable year. Such gain is distributed as a capital gain dividend and is taxable
to shareholders as gain from the sale or exchange of a capital asset held for
more than one year, regardless of the length of time a shareholder has held his
or her Fund shares and regardless of whether the distribution is paid in cash or
reinvested in shares. The Fund expect that capital gain dividends will be
taxable to shareholders as long-term gain. Capital gain dividends are not
eligible for the dividends received deduction.

     In the case of corporate shareholders, distributions of the Fund for any
taxable year generally qualify for the dividends received deduction to the
extent of the gross amount of "qualifying dividends" received by the Fund for
the year and if certain holding period requirements are met.  Generally, a
dividend will be treated as a "qualifying dividend" if it has been received from
a domestic corporation.

     If for any taxable year the Fund does not qualify as a regulated investment
company, all of its taxable income will be subject to tax at regular corporate
rates without any deduction for distributions to shareholders.  In such event,
all distributions (whether or not derived from exempt-interest income) would be
taxable as ordinary income and would be eligible for the dividends received
deduction in the case of corporate shareholders to the extent of the Fund's
current and accumulated earnings and profits.

                                       31
<PAGE>
 
     Shareholders will be advised annually as to the federal income tax
consequences of distributions made by the Fund each year.

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

     Although the Fund expects to qualify as a "regulated investment company"
and to be relieved of all or substantially all Federal income taxes, depending
upon the extent of its activities in states and localities in which its offices
are maintained, in which its agents or independent contractors are located or in
which it is otherwise deemed to be conducting business, the Fund may be subject
to the tax laws of such states or localities.

     The Trust will be required in certain cases to withhold and remit to the
United States Treasury 31% of taxable distributions, including gross proceeds
realized upon sale or other dispositions paid to any shareholder (i) who has
provided an incorrect tax identification number or no number at all, (ii) who is
subject to backup withholding by the Internal Revenue Service for failure to
report the receipt of taxable interest or dividend income properly, or (iii) who
has failed to certify that he is not subject to backup withholding or that he is
an "exempt recipient."

     DISPOSITION OF SHARES. Upon a redemption, sale or exchange of his or her
shares, a shareholder will realize a taxable gain or loss depending upon his or
her basis in the shares. Such gain or loss will be treated as capital gain or
loss if the shares are capital assets in the shareholder's hands and will be
long-term or short-term, generally, depending upon the shareholder's holding
period for the shares. Any loss realized on a redemption, sale or exchange will
be disallowed to the extent the shares disposed of are replaced (including
through reinvestment of dividends) within a period of 61 days beginning 30 days
before and ending 30 days after the shares are disposed of. In such a case, the
basis of the shares acquired will be adjusted to reflect the disallowed loss.
Any loss realized by a shareholder on the sale of Fund shares held by the
shareholder for six months or less will be treated as a long-term capital loss
to the extent of any distributions of net capital gains received or treated as
having been received by the shareholder with respect to such shares and treated
as long-term capital gains. Furthermore, a loss realized by a shareholder on the
redemption, sale or exchange of shares of the Fund with respect to which exempt-
interest dividends have been paid will, to the extent of such exempt-interest
dividends, be disallowed if such shares have been held by the shareholder for
six months or less.

     In some cases, shareholders will not be permitted to take sales charges
into account for purposes of determining the amount of gain or loss realized on
the disposition of their stock.  This prohibition generally applies where (1)
the shareholder incurs a sales charge in acquiring the stock of the Fund, (2)
the stock is disposed of before the 91st day after the date on which it was
acquired, and (3) the shareholder subsequently acquires the stock of the same or
another fund and the otherwise applicable sales charge is reduced under a
"reinvestment right" received upon the initial purchase of regulated investment
company shares.  The term "reinvestment right" means any right to acquire stock
of one or more funds without the payment of a sales charge or with the payment
of a reduced sales charge.  Sales charges affected by this rule are treated as
if they were incurred with respect to the stock acquired under the reinvestment
right.  This provision may be applied to successive acquisitions of Fund shares.

     Although the Fund expects to qualify as a "regulated investment company"
and to be relieved of all or substantially all federal income taxes, depending
upon the extent of its activities in states and localities in which 

                                       32
<PAGE>
 
its offices are maintained, in which its agents or independent contractors are
located or in which it is otherwise deemed to be conducting business, the Fund
may be subject to the tax laws of such states or localities.

     TAXATION OF CERTAIN FINANCIAL INSTRUMENTS.  Special rules govern the
Federal income tax treatment of financial instruments that may be held by the
Fund.  These rules may have a particular impact on the amount of income or gain
that the Fund must distribute to its shareholders to comply with the
Distribution Requirement, on the income or gain qualifying under the Income
Requirement, all described above.

     MARKET DISCOUNT.  If the Fund purchases a debt security at a price lower
than the stated redemption price of such debt security, the excess of the stated
redemption price over the purchase price is "market discount".  If the amount of
market discount is more than a de minimis amount, a portion of such market
discount must be included as ordinary income (not capital gain) by the Fund in
each taxable year in which the Fund owns an interest in such debt security and
receives a principal payment on it.  In particular, the Fund will be required to
allocate that principal payment first to the portion of the market discount on
the debt security that has accrued but has not previously been includable in
income.  In general, the amount of market discount that must be included for
each period is equal to the lesser of (i) the amount of market discount accruing
during such period (plus any accrued market discount for prior periods not
previously taken into account) or (ii) the amount of the principal payment with
respect to such period.  Generally, market discount accrues on a daily basis for
each day the debt security is held by the Fund at a constant rate over the time
remaining to the debt security's maturity or, at the election of the Fund, at a
constant yield to maturity which takes into account the semi-annual compounding
of interest.  Gain realized on the disposition of a market discount obligations
must be recognized as ordinary interest income (not capital gain) to the extent
of the "accrued market discount."

     ORIGINAL ISSUE DISCOUNT.  Certain debt securities acquired by the Fund may
be treated as debt securities that were originally issued at a discount.  Very
generally, original issue discount is defined as the difference between the
price at which a security was issued and its stated redemption price at
maturity.  Although no cash income on account of such discount is actually
received by the Fund, original issue discount that accrues on a debt security in
a given year generally is treated for federal income tax purposes as interest
and, therefore, such income would be subject to the distribution requirements
applicable to regulated investment companies.

     Some debt securities may be purchased by the Fund, at a discount that
exceeds the original issue discount on such debt securities, if any.  This
additional discount represents market discount for federal income tax purposes
(see above).

     HEDGING TRANSACTIONS. The taxation of equity options and over-the-counter
options on debt securities is governed by Internal Revenue Code section 1234.
Pursuant to Internal Revenue Code section 1234, the premium received by the Fund
for selling a put or call option is not included in income at the time of
receipt. If the option expires, the premium is short-term capital gain to the
Fund. If the Fund enters into a closing transaction, the difference between the
amount paid to close out its position and the premium received is short-term
capital gain or loss. If a call option written by the Fund is exercised, thereby
requiring the Fund to sell the underlying security, the premium will increase
the amount realized upon the sale of such security and any resulting gain or
loss will be a capital gain or loss, and will be long-term or short-term
depending upon the holding period of the security. With respect to a put or call
option that is purchased by the Fund, if the option is sold, any resulting gain
or loss will be a capital gain or loss, and will be long-term or short-term,
depending upon the holding period of the option. If the option expires, the
resulting loss is a capital loss and is long-term or short-term, depending upon
the holding period of the option. If the option is exercised, the cost of the
option, in the case of a call option, is added to the basis of the purchased
security and, in the case of a put option, reduces the amount realized on the
underlying security in determining gain or loss.

     Any regulated futures and foreign currency contracts and certain options
(namely, nonequity options and dealer equity options) in which the Fund may
invest may be "section 1256 contracts." Gains or losses on section 1256
contracts are generally considered 60% long-term and 40% short-term capital
gains or losses; however, foreign currency gains or losses arising from certain
section 1256 contracts may be treated as ordinary income or loss.  Also,
section, 1256 contracts held by the Fund at the end of each taxable year (and
generally for purposes of 

                                       33
<PAGE>
 
the 4% excise tax, on October 31 of each year) are "marked-to-market" with the
result that unrealized gains or losses are treated as though they were realized.

     Generally, hedging transactions, if any, undertaken by the Fund may result
in "straddles" for U.S. federal income tax purposes.  The straddle rules may
affect the character of gains (or losses) realized by the Funds.  In addition,
losses realized by the Fund on positions that are part of a straddle may be
deferred under the straddle rules, rather than being taken into account in
calculating the taxable income for the taxable year in which such losses are
realized.  Because only a few regulations implementing the straddle rules have
been promulgated, the tax consequences of hedging transactions to the Fund is
not entirely clear.  The hedging transactions may increase the amount of short-
term capital gain realized by the Fund which is taxed as ordinary income when
distributed to shareholders.

     The Fund may make one or more of the elections available under the Internal
Revenue Code which are applicable to straddles.  If the Fund makes any of the
elections, the amount, character and timing of the recognition of gains or
losses from the affected straddle positions will be determined under rules that
vary according to the election(s) made.  The rules applicable under certain of
the elections may operate to accelerate the recognition of gains or losses from
the affected straddle positions.

     Because application of the straddle rules may affect the character of gains
or losses, defer losses and/or accelerate the recognition of gains or losses
from the affected straddle positions, the amount which must be distributed to
shareholders, and which will be taxed to shareholders as ordinary income or
long-term capital gain, may be increased or decreased substantially as compared
to the fund that did not engage in such hedging transactions.

     The diversification requirements applicable to a Fund's assets may limit
the extent to which the Fund's will be able to engage in transactions in
options, futures or forward contracts.

     CONSTRUCTIVE SALES.  Recently enacted rules may affect the timing and
character of gain if the Fund engages in transactions that reduce or eliminate
its risk of loss with respect to appreciated financial positions.  If the Fund
enters into certain transactions in property while holding substantially
identical property, the Fund would be treated as if it had sold and immediately
repurchased the property and would be taxed on any gain (but not loss) from the
constructive sale.  The character of gain from a constructive sale would depend
upon the Fund's holding period in the property.  Loss from a constructive sale
would be recognized when the property was subsequently disposed of, and its
character would depend on the Fund's holding period and the application of
various loss deferral provisions of the Internal Revenue Code.

     CURRENCY FLUCTUATIONS - "SECTION 988" GAINS OR LOSSES.  Under the Internal
Revenue Code, gains or losses attributable to fluctuations in exchange rates
which occur between the time the Fund accrues receivables or liabilities
denominated in a foreign currency and the time the Fund actually collects such
receivables or pays such liabilities generally are treated as ordinary income
and loss.  Similarly, on disposition of debt securities denominated in a foreign
currency and on disposition of certain futures, forward contracts and options,
gains or losses attributable to fluctuations in the value of the foreign
currency between the date of acquisition of the security or contract and the
date of disposition also are treated as ordinary gain or loss.  These gains or
losses, referred to under the Internal Revenue Code as "Section 988" gains or
losses, may increase or decrease the amount of a Fund's investment company
taxable income to be distributed to its shareholders as ordinary income.

     PASSIVE FOREIGN INVESTMENT COMPANIES.  The Fund may invest in shares of
foreign corporations that may be classified under the Internal Revenue Code as
passive foreign investment companies ("PFICs").  In general, a foreign
corporation is classified as a PFIC if at least one-half of its assets
constitute investment-type assets, or 75% or more of its gross income
investment-type income.  If the Fund receives a so-called "excess distribution"
with respect to PFIC stock, the Fund itself may be subject to a tax on a portion
of the excess distribution, whether or not the corresponding income is
distributed by the Fund to shareholders.  In general, under the PFIC rules, an
excess distribution is treated as having been realized ratably over the period
during which the Fund held the PFIC shares.  The Fund will itself be subject to

Fund taxable years and an interest factor will be added to the tax, as if the
tax had been payable in such prior taxable years. Certain distributions from a
PFIC as well as gain from the sale of PFIC shares are treated as excess
distributions. Excess distributions are characterized as ordinary income even
though, absent application of the PFIC rules, certain excess distributions might
have been classified as capital gain.

     The Fund may be eligible to elect alternative tax treatment with respect to
PFIC shares.  Under an election that currently is available in some
circumstances, the Fund generally would be required to include in its gross
income its share of the earnings of a PFIC on a current basis, regardless of
whether distributions were received from the PFIC in a given year.  If this
election were made, the special rules, discussed above, relating to the taxation
of excess distributions, would not apply.  In addition, another election would
involve marking to market the Fund's PFIC shares at the end of each taxable
year, with the result that unrealized gains would be treated as though they were
realized and reported as ordinary income.  Any mark-to market losses and any
loss from an actual disposition of Fund shares would be deductible as ordinary
losses to the extent of any net mark-to-market gains included in income in prior
years.

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

     Fund shareholders may be subject to state, local and foreign taxes on their
Fund distributions.  In many states, Fund distributions which are derived from
interest on certain U.S. Government obligations are exempt from taxation.  The
tax consequences to a foreign shareholder of an investment in the Fund may be
different from those described herein.  Foreign shareholders are advised to
consult their own tax advisers with respect to the particular tax consequences
to them of an investment in the Fund.  Shareholders are advised to consult their
own tax advisers with respect to the particular tax consequences to them of an
investment in the Fund.

OTHER TAXATION

     The foregoing discussion relates only to U.S. federal income tax law and
certain state taxes as applicable to U.S. persons (i.e., U.S. citizens and
residents and domestic corporations, partnerships, trusts and estates).
Distributions by the Fund, and dispositions of Fund shares also may be subject
to other state and local taxes, and their treatment under state and local income
tax laws may differ from the U.S. federal income tax treatment. Shareholders
should consult their tax advisers with respect to particular questions of U.S.
federal, state and local taxation. Shareholders who are not U.S. persons should
consult their tax advisers regarding U.S. and foreign tax consequences of
ownership of shares of the Fund, including the likelihood that distributions to
them would be subject to withholding of U.S. federal income tax at a rate of 30%
(or at a lower rate under a tax treaty). Future legislative or administrative
changes or court decisions may significantly change the conclusions expressed
herein, and any such changes or decisions may have a retroactive effect with
respect to the transactions contemplated herein.

                   ADDITIONAL INFORMATION CONCERNING SHARES

     The Trust is a Massachusetts business trust.  Under the Declaration of
Trust, the beneficial interest in the Trust may be divided into an unlimited
number of full and fractional transferable shares.  The Trust's Declaration of
Trust authorize the Board of Trustees to classify or reclassify any unissued
shares of the Trust into one or more classes by setting or changing, in any one
or more respects, their respective designations, preferences, conversion or
other rights, voting powers, restrictions, limitations, qualifications and terms
and conditions of redemption.  Pursuant to such authority, the Trust's Board of
Trustees has authorized the issuance of an unlimited number of shares of
beneficial interest in the Trust, representing interests in the Accelerating
Growth, Balanced, Growth & Income, Index 500, International Equity, Small
Company Growth, Bond, Intermediate Bond, U.S. Government Income, Michigan Bond,
Tax-Free Bond, Tax-Free Intermediate Bond, Cash Investment, Tax-Free Money
Market and U.S. Treasury Money Market Funds.  The shares of each Fund (other
than the Cash Investment Fund, Tax-Free Money Market Fund and U.S. Treasury
Money Market Fund) are offered in five separate classes: Class A, Class B, Class
C, Class K and Class Y Shares.  The Cash Investment Fund, Tax-Free Money Market
Fund and U.S. Treasury Money Market Fund offer only Class Y Shares, Class K
Shares and Class A Shares.

                                       35

     The Trust adopted a plan pursuant to Rule 18f-3 under the 1940 Act ("Multi-
Class Plan") on behalf of the Fund.  The Multi-Class Plan provides that shares
of each class of the Fund are identical, except for one or more expense
variables, certain related rights, exchange privileges, class designation and
sales loads assessed due to differing distribution methods.
     

     In the event of a liquidation or dissolution of the Trust or the Fund,
shareholders of the Fund would be entitled to receive the assets available for
distribution belonging to the Fund, and a proportionate distribution, based upon
the relative net asset values of the Fund, of any general assets not belonging
to the Fund which are available for distribution.  Shareholders of the Fund are
entitled to participate in the net distributable assets of the Fund on
liquidation, based on the number of shares of the Fund that are held by each
shareholder.

     Holders of all outstanding shares of the Fund will vote together in the
aggregate and not by class on all matters, except that only Class A Shares of
the Fund will be entitled to vote on matters submitted to a vote of shareholders
pertaining to the Fund's Class A Plan, only Class B Shares of the Fund will be
entitled to vote on matters submitted to a vote of shareholders pertaining to
the Fund's Class B Plan, only Class C Shares of the Fund will be entitled to
vote on matters submitted to a vote of shareholders pertaining to the Fund's
Class C Plan, and only Class K Shares of the Fund will be entitled to vote on
matters submitted to a vote of shareholders pertaining to the Class K Plan.
Further, shareholders of the Fund, as well as those of any other investment
portfolio now or hereafter offered by the Trust, will vote together in the
aggregate and not separately on a Fund-by-Fund basis, except as otherwise
required by law or when permitted by the Board of Trustees.  Rule 18f-2 under
the 1940 Act provides that any matter required to be submitted to the holders of
the outstanding voting securities of an investment company such as the Trust
shall not be deemed to have been effectively acted upon unless approved by the
holders of a majority of the outstanding shares of the Fund affected by the
matter.  The Fund is affected by a matter, (i) unless it is clear that the
interests of the Fund in the matter are substantially identical or (ii) that the
matter does not affect any interest of the Fund.  Under the Rule, the approval
of an investment advisory agreement, sub-advisory agreement or any change in a
fundamental investment policy would be effectively acted upon with respect to
the Fund only if approved by a majority of the outstanding shares of the Fund.
However, the Rule also provides that the ratification of the appointment of
independent auditors, the approval of principal underwriting contracts and the
election of trustees may be effectively acted upon by shareholders of the Trust
voting together in the aggregate without regard to the Fund.

     Shares of the Trust have noncumulative voting rights and, accordingly, the
holders of more than 50% of the Trust's outstanding shares (irrespective of
class) may elect all of the trustees. Shares have no preemptive rights and only
such conversion and exchange rights as the Board may grant in its discretion.
When issued for payment as described in the applicable Prospectus, shares will
be fully paid and non-assessable by the Trust.

     Shareholder meetings to elect trustees will not be held unless and until
such time as required by law.  At that time, the trustees then in office will
call a shareholders' meeting to elect trustees.  Except as set forth above, the
trustees will continue to hold office and may appoint successor trustees.
Meetings of the shareholders of the Trust shall be called by the trustees upon
the written request of shareholders owning at least 10% of the outstanding
shares entitled to vote.

     The Trust's Declaration of Trust, as amended, authorizes the Board of
Trustees, without shareholder approval (unless otherwise required by applicable
law), to: (i) sell and convey the assets belonging to a class of shares to
another management investment company for consideration which may include
securities issued by the purchaser and, in connection therewith, to cause all
outstanding shares of such class to be redeemed at a price which is equal to
their net asset value and which may be paid in cash or by distribution of the
securities or other consideration received from the sale and conveyance; (ii)
sell and convert the assets belonging to one or more classes of shares into
money and, in connection therewith, to cause all outstanding shares of such
class to be redeemed at their net asset value; or (iii) combine the assets
belonging to a class of shares with the assets belonging to one or more other
classes of shares if the Board of Trustees reasonably determines that such
combination will not have a material adverse effect on the shareholders of any
class participating in such combination and, in connection therewith, to cause
all outstanding shares of any such class to be redeemed or converted into shares
of another class 

                                       36
<PAGE>
 
of shares at their net asset value. However, the exercise of such authority may
be subject to certain restrictions under the 1940 Act. The Trust's Board of
Trustees may authorize the termination of any class of shares after the assets
belonging to such class have been distributed to its shareholders.

     Excerpts from MOODY'S INVESTORS SERVICES, INC.  ("MOODY'S") description of
its bond ratings:

     "Aaa":
            Bonds that 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 edge." 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 that 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.

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

     "Baa":
            Bonds that are rated "Baa" are considered as medium grade
       obligations, i.e., they are neither highly protected nor poorly secured.
       Interest payments and principal security appears 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 that 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 that are rated "B" generally lack characteristics of desirable
       investments.  Assurance of interest and principal payments or of
       maintenance of other terms of the contract over any long period of time
       may be small.

     "Caa":
            Bonds that are rated "Caa" are of poor standing. These issues may be
       in default or present elements of danger may exist with respect to
       principal or interest.

     Moody's applies numerical modifiers (1, 2 and 3) with respect to bonds
rated "Aa" through "B". The modifier 1 indicates that the bond being rated 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 bond ranks in the lower
end of its generic rating category.

     Excerpts from STANDARD & POOR'S CORPORATION ("S&P") description of its 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 "AAA" issues by a 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":
            Bonds rated "BBB" are regarded as having an adequate capacity to pay
       interest and repay principal.  Whereas they normally exhibit 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 bonds in this category than for bonds in
       higher rated categories.

     "BB", "B" AND "CCC":

            Bonds rated "BB" and "B" are regarded, on balance, as predominantly
       speculative with respect to capacity to pay interest and repay principal
       in accordance with the terms of the obligations.  "BB" represents a lower
       degree of speculation  than "B" and "CCC" the highest degree of
       speculation.  While such bonds will likely have some quality and
       protective characteristics, these are outweighed by large uncertainties
       or major risk exposures to adverse conditions.

     To provide more detailed indications of credit quality, the "AA" or "A"
ratings may be modified by the addition of a plus or minus sign to show relative
standing within these major rating categories.

COMMERCIAL PAPER
- ----------------

     The rating "PRIME-1" is the highest commercial paper rating assigned by
MOODY'S.  These issues (or related supporting institutions) are considered to
have a superior capacity for repayment of short-term promissory obligations.
Issues rated "PRIME-2" (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations.  This will normally
be evidenced by many of the characteristics of "Prime-1" rated issues, but to a
lesser degree.  Earnings trends and coverage ratios, while sound, will be more
subject to variation.  Capitalization characteristics, while still appropriate,
may be more affected by external conditions.  Ample alternate liquidity is
maintained.

     Commercial paper ratings of S&P are current assessments of the likelihood
of timely payment of debt having original maturities of no more than 365 days.
Commercial paper rated "A-1" by S&P indicates that the degree of safety
regarding timely payment is either overwhelming or very strong.  Those issues
determined to possess overwhelming safety characteristics are denoted "A-1+."
Commercial paper rated "A-2" by S&P indicates that capacity for timely payment
is strong.  However, the relative degree of safety is not as high as for issues
designated "A-1."

COMMERCIAL PAPER

     Rated commercial paper purchased by a Fund must have (at the time of
purchase) the highest quality rating assigned to short-term debt securities or,
if not rated, or rated by only one agency, are determined to be of comparative
quality pursuant to guidelines approved by a Fund's Board of Trustees.  Highest
quality ratings for commercial paper for Moody's and S&P are as follows:

     MOODY'S: The rating "PRIME-1" is the highest commercial paper rating
     -------

are considered to have a superior capacity for repayment of short-term
promissory obligations.

likelihood of timely payment of debts having original maturities of no more than
365 days.  Commercial paper rated in the "A-1" category by S&P indicates that
the degree of safety regarding timely payment is either overwhelming or very
strong.  Those issues determined to possess overwhelming safety characteristics
are denoted "A-1+".

     As stated in the Prospectuses, the Fund may enter into certain futures
transactions and options for hedging purposes. Such transactions are described
in this Appendix.

I.   INTEREST RATE FUTURES CONTRACTS
     -------------------------------

     USE OF INTEREST RATE FUTURES CONTRACTS.  Bond prices are established in 
     ---------------------------------------                                
both the cash market and the futures market. In the cash market, bonds are
purchased and sold with payment for the full purchase price of the bond being
made in cash, generally within five business days after the trade. In the
futures market, only a contract is made to purchase or sell a bond in the future
for a set price on a certain date. Historically, the prices for bonds
established in the futures markets have tended to move generally in the
aggregate in concert with the cash market prices and have maintained fairly
predictable relationships. Accordingly, the Fund may use interest rate futures
contracts as a defense, or hedge, against anticipated interest rate changes and
not for speculation. As described below, this would include the use of futures
contract sales to protect against expected increases in interest rates and
futures contract purchases to offset the impact of interest rate declines.

     The Fund presently could accomplish a similar result to that which it hopes
to achieve through the use of futures contracts by selling bonds with long
maturities and investing in bonds with short maturities when interest rates are
expected to increase, or conversely, selling short-term bonds and investing in
long-term bonds when interest rates are expected to decline. However, because of
the liquidity that is often available in the futures market, the protection is
more likely to be achieved, perhaps at a lower cost and without changing the
rate of interest being earned by the Fund, through using futures contracts.

     DESCRIPTION OF INTEREST RATE FUTURES CONTRACTS.  An interest rate futures
     -----------------------------------------------                          
contract sale would create an obligation by the Fund, as seller, to deliver the
specific type of financial instrument called for in the contract at a specific
future time for a specified price. A futures contract purchase would create an
obligation by the Fund, as purchaser, to take delivery of the specific type of
financial instrument at a specific future time at a specific price. The specific
securities delivered or taken, respectively, at settlement date, would not be
determined until or at near that date. The determination would be in accordance
with the rules of the exchange on which the futures contract sale or purchase
was made.

     Although interest rate futures contracts by their terms call for actual
delivery or acceptance of securities, in most cases the contracts are closed out
before the settlement date without making or taking of delivery of securities.
Closing out a futures contract sale is effected by the Fund's entering into a
futures contract purchase for the same aggregate amount of the specific type of
financial instrument and the same delivery date. If the price of the sale
exceeds the price of the offsetting purchase, the Fund is immediately paid the
difference and thus realizes a gain. If the offsetting purchase price exceeds
the sale price, the Fund pays the difference and realizes a loss. Similarly, the
closing out of a futures contract purchase is effected by the Fund entering into
a futures contract sale. If the offsetting sale price exceeds the purchase
price, the Fund realizes a gain, and if the purchase price exceeds the
offsetting sale price, the Fund realizes a loss.

     Interest rate futures contracts are traded in an auction environment on the
floors of several exchanges -principally, the Chicago Board of Trade, the
Chicago Mercantile Exchange and the New York Futures Exchange. The Fund would
deal only in standardized contracts on recognized exchanges. Each exchange
guarantees performance under contract provisions through a clearing corporation,
a nonprofit organization managed by the exchange membership.

     A public market now exists in futures contracts covering various financial
instruments including long-term United States Treasury Bonds and Notes,
Government National Mortgage Association (GNMA) modified pass-through mortgage
backed securities, three-month United States Treasury Bills, and ninety-day
commercial paper. The Funds may trade in any interest rate futures contracts for
which there exists a public market, including, without limitation, the foregoing
instruments.

     EXAMPLE OF FUTURES CONTRACT SALE.  The Fund would engage in an interest
     ---------------------------------                                      
rate futures contract sale to maintain the income advantage from continued
holding of a long-term bond while endeavoring to avoid part or all of the loss
in market value that would otherwise accompany a decline in long-term securities
prices. Assume that the market value of a certain security held by the Fund
tends to move in concert with the futures market prices of long-term United
States Treasury bonds ("Treasury Bonds"). The advisor wishes to fix the current
market value of the portfolio security until some point in the future. Assume
the portfolio security has a market value of 100, and the advisor believes that,
because of an anticipated rise in interest rates, the value will decline to 95.
The fund might enter into futures contract sales of Treasury bonds for an
equivalent of 98. If the market value of the portfolio security does indeed
decline from 100 to 95, the equivalent futures market price for the Treasury
bonds might also decline from 98 to 93.

     In that case, the five point loss in the market value of the portfolio
security would be offset by the five point gain realized by closing out the
futures contract sale. Of course, the futures market price of Treasury bonds
might well decline to more than 93 or to less than 93 because of the imperfect
correlation between cash and futures prices mentioned below.

     The advisor could be wrong in its forecast of interest rates and the
equivalent futures market price could rise above 98. In this case, the market
value of the portfolio securities, including the portfolio security being
protected, would increase. The benefit of this increase would be reduced by the
loss realized on closing out the futures contract sale.

     If interest rate levels did not change, the Fund in the above example might
incur a loss of 2 points (which might be reduced by an offsetting transaction
prior to the settlement date). In each transaction, transaction expenses would
also be incurred.

     EXAMPLE OF FUTURES CONTRACT PURCHASE.  The Fund would engage in an interest
     -------------------------------------                                      
rate futures contract purchase when they are not fully invested in long-term
bonds but wish to defer for a time the purchase of long-term bonds in light of
the availability of advantageous interim investments, e.g., shorter term
securities whose yields are greater than those available on long-term bonds. The
Fund's basic motivation would be to maintain for a time the income advantage
from investing in the short-term securities; the Fund would be endeavoring at
the same time to eliminate the effect of all or part of an expected increase in
market price of the long-term bonds that the Fund may purchase.

     For example, assume that the market price of a long-term bond that the Fund
may purchase, currently yielding 10% , tends to move in concert with futures
market prices of Treasury bonds. The advisor wishes to fix the current market
price (and thus 10% yield) of the long-term bond until the time (four months
away in this example) when it may purchase the bond. Assume the long-term bond
has a market price of 100, and the advisor believes that, because of an
anticipated fall in interest rates, the price will have risen to 105 (and the
yield will have dropped to about 91/2%) in four months. The Fund might enter
into futures contracts purchases of Treasury bonds for an equivalent price of
98. At the same time, the Fund would assign a pool of investments in short-term
securities that are either maturing in four months or earmarked on the books of
the Fund or the Fund's sub-custodian for sale in four months, for purchase of
the long-term bond at an assumed market price of 100. Assume these short-term
securities are yielding 15%. If the market price of the long-term bond does
indeed rise from 100 to 105, the equivalent futures market price for Treasury
bonds might also rise from 98 to 103. In that case, the 5 point increase in the
price that the Fund pays for the long-term bond would be offset by the 5 point
gain realized by closing out the futures contract purchase.

     The advisor could be wrong in its forecast of interest rates; long-term
interest rates might rise to above 10%; and the equivalent futures market price
could fall below 98. If short-term rates at the same time fall to 10% or below,
it is possible that the Fund would continue with its purchase program for long-
term bonds. The market price of available long-term bonds would have decreased.
The benefit of this price decrease, and thus yield increase, will be reduced by
the loss realized on closing out the futures contract purchase.

                                      B-2
<PAGE>
 
     If, however, short-term rates remained above available long-term rated, it
is possible that the Fund would discontinue its purchase program for long-term
bonds. The yield on short-term securities in the portfolio, including those
originally in the pool assigned to the particular long-term bond, would remain
higher than yields on long-term bonds. The benefit of this continued incremental
income will be reduced by the loss realized on closing out the futures contract
purchase. In each transaction, expenses would also be incurred.

II.  INDEX FUTURES CONTRACTS
     -----------------------

     GENERAL.  A bond index assigns relative values of the bonds included in the
     --------                                                                   
index and the index fluctuates with changes in the market values of the bonds
included. The Chicago Board of Trade has designed a futures contract based on
the Bond Buyer Municipal Bond Index. This Index is composed of 40 term revenue
and general obligation bonds and its composition is updated regularly as new
bonds meeting the criteria of the Index are issued and existing bonds mature.
The Index is intended to provide an accurate indicator of trends and changes in
the municipal bond market. Each bond in the Index is independently priced by six
dealer-to-dealer municipal bond brokers daily. The 40 prices then are averaged
and multiplied by a coefficient. The coefficient is used to maintain the
continuity of the Index when its composition changes.

     A stock index assigns relative values to the stocks included in the index
and the index fluctuates with changes in the market values of the stocks
included. Some stock index futures contracts are based on broad market indices,
such as the Standard & Poor's 500 or the New York Stock Exchange Composite
Index. In contrast, certain exchanges offer futures contracts on narrower market
indices, such as the Standard & Poor's 100 or indices based on an industry or
market segment, such as oil and gas stocks.

     Futures contracts are traded on organized exchanges regulated by the
Commodity Futures Trading Commission. Transactions on such exchanges are cleared
through a clearing corporation, which guarantees the performance of the parties
to each contract.

     The Fund will sell index futures contracts in order to offset a decrease in
market value of its portfolio securities that might otherwise result from a
market decline. The Fund will purchase index futures contracts in anticipation
of purchases of securities. In a substantial majority of these transactions, the
Fund will purchase such securities upon termination of the long futures
position, but a long futures position may be terminated without a corresponding
purchase of securities.

     In addition, the Fund may utilize index futures contracts in anticipation
of changes in the composition of its portfolio holdings. For example, in the
event that the Fund expects to narrow the range of industry groups represented
in its holdings it may, prior to making purchases of the actual securities,
establish a long futures position based on a more restricted index, such as an
index comprised of securities of a particular industry group. The Fund may also
sell futures contracts in connection with this strategy, in order to protect
against the possibility that the value of the securities to be sold as part of
the restructuring of the portfolio will decline prior to the time of sale.

</TABLE>

III.  MARGIN PAYMENTS
      ---------------

      Unlike purchase or sales of portfolio securities, no price is paid or
received by the Fund upon the purchase or sale of a futures contract. Initially,
the Fund will be required to deposit with the broker or earmarked on the books
of the Fund or the Fund's sub-custodian in an amount of cash or cash
equivalents, known as initial margin, based on the value of the contract. The
nature of initial margin in futures transactions is different from that of
margin in security transactions in that futures contract margin does not involve
the borrowing of funds by the customer to finance the transactions. Rather, the
initial margin is in the nature of a performance bond or good faith deposit on
the contract which is returned to the Fund upon termination of the futures
contract assuming all contractual obligations have been satisfied. Subsequent
payments, called variation margin, to and from the broker, will be made on a
daily basis as the price of the underlying instruments fluctuates making the
long and short positions in the futures contract more or less valuable, a
process known as marking-to-the-market. For example, when the Fund has purchased
a futures contract and the price of the contract has risen in response to a rise
in the underlying instruments, that position will have increased in value and
the Fund will be entitled to receive from the broker a variation margin payment
equal to that increase in value. Conversely, where the Fund has purchased a
futures contract and the price of the futures contract has declined in response
to a decrease in the underlying instruments, the position would be less valuable
and the Fund would be required to make a variation margin payment to the broker.
At any time prior to expiration of the futures contract, the Advisor may elect
to close the position by taking an opposite position, subject to the
availability of a secondary market, which will operate to terminate the Fund's
position in the futures contract. A final determination of variation margin is
then made, additional cash is required to be paid by or released to the Fund,
and the Fund realizes a loss or gain.

IV.   RISKS OF TRANSACTIONS IN FUTURES CONTRACTS
      ------------------------------------------

      There are several risks in connection with the use of futures by the Fund
as hedging devices. One risk arises because of the imperfect correlation between
movements in the price of the futures and movements in the price of the
instruments which are the subject of the hedge. The price of the future may move
more than or less than the price of the instruments being hedged. If the price
of the futures moves less than the price of the instruments which are the
subject of the hedge, the hedge will not be fully effective but, if the price of
the instruments being hedged has moved in an unfavorable direction, the Fund
would be in a better position than if it had not hedged at all. If the price of
the instruments being hedged has moved in a favorable direction, this advantage
will be partially offset by the loss on the futures. If the price of the futures
moves more than the price of the hedged instruments, the Fund involved will
experience either a loss or gain on the futures which will not be

                                      B-4
<PAGE>
 
completely offset by movements in the price of the instruments which are the
subject of the hedge. To compensate for the imperfect correlation of movements
in the price of instruments being hedged and movements in the price of futures
contracts, the Fund may buy or sell futures contracts in a greater dollar amount
than the dollar amount of instruments being hedged if the volatility over a
particular time period of the prices of such instruments has been greater than
the volatility over such time period of the futures, or if otherwise deemed to
be appropriate by the Advisor. Conversely, the Fund may buy or sell fewer
futures contracts if the volatility over a particular time period of the prices
of the instruments being hedged is less than the volatility over such time
period of the futures contract being used, or if otherwise deemed to be
appropriate by the Advisor. It is also possible that, when the Fund had sold
futures to hedge its portfolio against a decline in the market, the market may
advance and the value of instruments held in the Fund may decline. If this
occurred, the Fund would lose money on the futures and also experience a decline
in value in its portfolio securities.

     Where futures are purchased to hedge against a possible increase in the
price of securities before the Fund is able to invest its cash (or cash
equivalents) in an orderly fashion, it is possible that the market may decline
instead; if the Fund then concludes not to invest its cash at that time because
of concern as to possible further market decline or for other reasons, the Fund
will realize a loss on the futures contract that is not offset by a reduction in
the price of the instruments that were to be purchased.

     In instances involving the purchase of futures contracts by the Fund, an
amount of cash and cash equivalents, equal to the market value of the futures
contracts, will be earmarked on the books of the Fund or the Fund's sub-
custodian to collateralize the position and thereby insure that the use of such
futures is unleveraged.

     In addition to the possibility that there may be an imperfect correlation,
or no correlation at all, between movements in the futures and the instruments
being hedged, the price of futures may not correlate perfectly with movement in
the cash market due to certain market distortions. Rather than meeting
additional margin deposit requirements, investors may close futures contracts
through off-setting transactions which could distort the normal relationship
between the cash and futures markets. Second, with respect to financial futures
contracts, the liquidity of the futures market depends on participants entering
into off-setting transactions rather than making or taking delivery. To the
extent participants decide to make or take delivery, liquidity in the futures
market could be reduced thus producing distortions. Third, from the point of
view of speculators, the deposit requirements in the futures market are less
onerous than margin requirements in the securities market. Therefore, increased
participation by speculators in the futures market may also cause temporary
price distortions. Due to the possibility of price distortion in the futures
market, and because of the imperfect correlation between the movements in the
cash market and movements in the price of futures, a correct forecast of general
market trends or interest rate movements by the Advisor may still not result in
a successful hedging transaction over a short time frame.

     Positions in futures may be closed out only on an exchange or board of
trade which provides a secondary market for such futures. Although the Fund
intends to purchase or sell futures only on exchanges or boards of trade where
there appear to be active secondary markets, there is no assurance that a liquid
secondary market on any exchange or board of trade will exist for any particular
contract or at any particular time. In such event, it may not be possible to
close a futures investment position, and in the event of adverse price
movements, the Fund would continue to be required to make daily cash payments of
variation margin. However, in the event futures contracts have been used to
hedge portfolio securities, such securities will not be sold until the futures
contract can be terminated. In such circumstances, an increase in the price of
the securities, if any, may partially or completely offset losses on the futures
contract. However, as described above, there is no guarantee that the price of
the securities will in fact correlate with the price movements in the futures
contract and thus provide an offset on a futures contract.

     Further, it should be noted that the liquidity of a secondary market in a
futures contract may be adversely affected by "daily price fluctuation limits"
established by commodity exchanges which limit the amount of fluctuation in a
futures contract price during a single trading day. Once the daily limit has
been reached in the contract, no trades may be entered into at a price beyond
the limit, thus preventing the liquidation of open futures positions. The
trading of futures contracts is also subject to the risk of trading halts,
suspensions, exchange or clearing house equipment failures, government
intervention, insolvency of a brokerage firm or clearing house or

                                      B-5
<PAGE>
 
other disruptions of normal activity, which could at times make it difficult or
impossible to liquidate existing positions or to recover excess variation margin
payments.

     Successful use of futures by the Fund is also subject to the Advisor's
ability to predict correctly movements in the direction of the market. For
example, if the Fund has hedged against the possibility of a decline in the
market adversely affecting securities held by it and securities prices increase
instead, the Fund will lose part or all of the benefit to the increased value of
its securities which it has hedged because it will have offsetting losses in its
futures positions. In addition, in such situations, if the Fund has insufficient
cash, it may have to sell securities to meet daily variation margin
requirements. Such sales of securities may be, but will not necessarily be, at
increased prices which reflect the rising market. The Fund may have to sell
securities at a time when it may be disadvantageous to do so.

V.   OPTIONS ON FUTURES CONTRACTS
     ----------------------------

     The Fund may purchase and write options on the futures contracts described
above. A futures option gives the holder, in return for the premium paid, the
right to buy (call) from or sell (put) to the writer of the option a futures
contract at a specified price at any time during the period of the option. Upon
exercise, the writer of, the option is obligated to pay the difference between
the cash value of the futures contract and the exercise price. Like the buyer or
seller of a futures contract, the holder, or writer, of an option has the right
to terminate its position prior to the scheduled expiration of the option by
selling, or purchasing an option of the same series, at which time the person
entering into the closing transaction will realize a gain or loss. The Fund will
be required to deposit initial margin and variation margin with respect to put
and call options on futures contracts written by it pursuant to brokers'
requirements similar to those described above. Net option premiums received will
be included as initial margin deposits.

     Investments in futures options involve some of the same considerations that
are involved in connection with investments in future contracts (for example,
the existence of a liquid secondary market). In addition, the purchase or sale
of an option also entails the risk that changes in the value of the underlying
futures contract will not correspond to changes in the value of the option
purchased. Depending on the pricing of the option compared to either the futures
contract upon which it is based, or upon the price of the securities being
hedged, an option may or may not be less risky than ownership of the futures
contract or such securities. In general, the market prices of options can be
expected to be more volatile than the market prices on underlying futures
contract. Compared to the purchase or sale of futures contracts, however, the
purchase of call or put options on futures contracts may frequently involve less
potential risk to the Fund because the maximum amount at risk is the premium
paid for the options (plus transaction costs). The writing of an option on a
futures contract involves risks similar to those risks relating to the sale of
futures contracts.

VI.  CURRENCY TRANSACTIONS
     ---------------------

     The Fund may engage in currency transactions in order to hedge the value of
portfolio holdings denominated in particular currencies against fluctuations in
relative value. Currency transactions include forward currency contracts,
currency futures, options on currencies, and currency swaps. A forward currency
contract involves a privately negotiated obligation to purchase or sell (with
delivery generally required) a specific currency at a future date, which may be
any fixed number of days from the date of the contract agreed upon by the
parties, at a price set at the time of the contract. A currency swap is an
agreement to exchange cash flows based on the notional difference among two or
more currencies and operates similarly to an interest rate swap as described in
the Statement of Additional Information. The Fund may enter into currency
transactions with counterparties which have received (or the guarantors of the
obligations which have received) a credit rating of A-1 or P-1 by S&P or
Moody's, respectively, or that have an equivalent rating from a NRSRO or are
determined to be of equivalent credit quality by the Advisor.

     The Fund's dealings in forward currency contracts and other currency
transactions such as futures, options, options on futures and swaps will be
limited to hedging involving either specific transactions or portfolio
positions. Transaction hedging is entering into a currency transaction with
respect to specific assets or liabilities of the Fund,

                                      B-6
<PAGE>
 
which will generally arise in connection with the purchase or sale of its
portfolio securities or the receipt of income therefrom. Position hedging is
entering into a currency transaction with respect to portfolio security
positions denominated or generally quoted in that currency.

      The Fund will not enter into a transaction to hedge currency exposure to
an extent greater after netting all transactions intended wholly or partially to
offset other transactions, than the aggregate market value (at the time of
entering into the transaction) of the securities held in its portfolio that are
denominated or generally quoted in or currently convertible into such currency,
other than with respect to proxy hedging as described below.

      The Fund may also cross-hedge currencies by entering into transactions to
purchase or sell one or more currencies that are expected to decline in value
relative to other currencies to which the Fund has or in which the Fund expects
to have portfolio exposure.

      To reduce the effect of currency fluctuations on the value of existing or
anticipated holdings of portfolio securities, the Fund may also engage proxy
hedging. Proxy hedging is often used when the currency to which the Fund's
portfolio is exposed is difficult to hedge or to hedge against the dollar. Proxy
hedging entails entering into a commitment or option to sell a currency whose
changes in value are generally considered to be correlated to a currency or
currencies in which some or all of the Fund's portfolio securities are or are
expected to be denominated, in exchange for U.S. dollars. The amount of the
commitment or option would not exceed the value of the Fund's securities
denominated in correlated currencies. For example, if the Advisor considers that
the Austrian schilling is correlated to the German mark (the "D-mark"), the Fund
holds securities denominated in shillings and the Advisor believes that the
value of the schillings will decline against the U.S. dollar, the Advisor may
enter into a commitment or option to sell D-marks and buy dollars. Currency
hedging involves some of the same risks and considerations as other transactions
with similar instruments. Currency transactions can result in losses to the Fund
if the currency being hedged fluctuates in value to a degree or in a direction
that is not anticipated. Further, there is the risk that the perceived
correlation between various currencies may not be present or may not be present
during the particular time that the Fund is engaging in proxy hedging. If the
Fund enters into a currency hedging transaction, the Fund will earmark liquid,
high grade assets on the books of the Fund or the Fund's sub-custodian to the
extent the Fund's obligations are not otherwise "covered" through ownership of
the underlying currency.

      Currency transactions are subject to risks different from those of other
portfolio transactions. Because currency control is of great importance to the
issuing governments and influences economic planning and policy, purchases and
sales of currency and related instruments can be negatively affected by
government exchange controls, blockages, and manipulations or exchange
restrictions imposed by governments. These can result in losses to the Fund if
it is unable to deliver or receive currency or funds in settlement of
obligations and could also cause hedges it has entered into to be rendered
useless, resulting in full currency exposure as well as incurring transaction
costs. Buyers and sellers of currency futures are subject to the same risks that
apply to the use of futures generally. Further, settlement of a currency futures
contract for the purchase of most currencies must occur at a bank based in the

Exhibit 8(a) hereto.  Registrant has obtained from a major insurance carrier a
trustees' and officers' liability policy covering certain types of errors and
omissions. In addition, Section 9.3 of the Registrant's Agreement and
Declaration of Trust incorporated herein by reference as Exhibit 1(a) hereto
provides as follows:     

     Indemnification of Trustees, Officers, Representatives and Employees. The
Trust shall indemnify each of its Trustees against all liabilities and expenses
(including amounts paid in satisfaction of judgments, in compromise, as fines
and penalties, and as counsel fees) reasonably incurred by him in connection
with the defense or disposition of any action, suit or other proceeding, whether
civil or criminal in which he may be involved or with which he may be
threatened, while as a Trustee or thereafter, by reason of his being or having
been such a Trustee except with respect to any matter as to which he shall have
been adjudicated to have acted in bad faith, willful misfeasance, gross
negligence or reckless disregard of his duties, provided that as to any matter
disposed of by a compromise payment by such person, pursuant to a consent decree
or otherwise, no indemnification either for said payment or for any other
expenses shall be provided unless the Trust shall have received a written
opinion from independent legal counsel approved by the Trustees to the effect
that if either the matter of willful 
<PAGE>
 
misfeasance, gross negligence or reckless disregard of duty, or the matter of
bad faith had been adjudicated, it would in the opinion of such counsel have
been adjudicated in favor of such person. The rights accruing to any person
under these provisions shall not exclude any other right to which he may be
lawfully entitled, provided that no person may satisfy any right of indemnity or
reimbursement hereunder except out of the property of the Trust. The Trustees
may make advance payments in connection with the indemnification under this
Section 9.3, provided that the indemnified person shall have given a written
undertaking to reimburse the Trust in the event it is subsequently determined
that he is not entitled to such indemnification.

     The Trustees shall indemnify officers, representatives and employees of the
Trust to the same extent that Trustees are entitled to indemnification pursuant
to this Section 9.3.

     Insofar as indemnification for liability arising under the Securities Act
of 1933 may be permitted to trustees, officers and controlling persons of
Registrant pursuant to the foregoing provisions, or otherwise, Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by Registrant of expenses incurred or
paid by a trustee, officer or controlling person of 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,
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 Act and will be governed by the final adjudication of such
issue.

     Section 9.6 of the Registrant's Agreement and Declaration of Trust,
incorporated herein by reference as Exhibit 1(a), also provides for the
indemnification of shareholders of the Registrant. Section 9.6 states as
follows:

     Indemnification of Shareholders. In case any Shareholder or former
Shareholder shall be held to be personally liable solely by reason of his being
or having been a Shareholder and not because of his acts or omissions or for
some other reason, the Shareholder or former Shareholder (or his heirs,
executors, administrators or other legal representatives or, in the case of a
corporation or other entity, its corporate or other general successor) shall be
entitled out of the assets belonging to the classes of Shares with the same
alphabetical designation as that of the Shares owned by such Shareholder to be
held harmless from and indemnified against all loss and expense arising from
such liability. The Trust shall, upon request by the Shareholder, assume the
defense of any claim made against any Shareholder for any act or obligations of
the Trust and satisfy any judgment thereon from such assets.

INTRODUCTION
- ------------

WHAT'S NEW IN THE WORLD OF IRAS?

     An Individual Retirement Account ("IRA") has always provided an attractive
means to save money for the future on a tax-advantaged basis.  Recent changes to
Federal tax law have now made the IRA an even more flexible investment and
savings vehicle.  Among the new changes is the creation of the Roth Individual
Retirement Account ("Roth IRA"), which will be available for use after January
1, 1998.  Under a Roth IRA, the earnings and interest on an individual's
nondeductible contributions grow without being taxed, and distributions may be
tax-free under certain circumstances.  Most taxpayers (except for those with
very high income levels) will be eligible to contribute to a Roth IRA.  A Roth
IRA can be used instead of a Regular IRA, to replace an existing Regular IRA, or
complement a Regular IRA you wish to continue maintaining.

     Taxpayers with adjusted gross income of up to $100,000 are eligible to
convert existing IRAs into Roth IRAs.  The details on conversion are found in
the description of Roth IRAs in this booklet.

     Congress has also made significant changes to Regular IRAs.  First,
Congress increased the income levels at which IRA holders who participate in
employer-sponsored retirement plans can make deductible Regular IRA
contributions.  Also the rules for deductible contributions by an IRA holder
whose spouse is a participant in an employer-sponsored retirement plan have been
liberalized.  Second, the 10% penalty tax for premature withdrawals (before age
59 1/2) will no longer apply in the case of withdrawals to pay certain higher
education expenses or certain first-time homebuyer expenses.

WHAT'S IN THIS KIT?

     In this Kit you will find detailed information about Roth IRAs and about
the changes that have been made to Regular IRAs.  You will also find everything
you need to establish and maintain either a Regular or Roth IRA, or to convert
all or part of an existing Regular IRA to a Roth IRA.

     The first section of this Kit contains the instructions and forms you will
need to open a new Regular or Roth IRA, to transfer from another IRA to a State
Street Bank and Trust IRA, or to convert a Regular IRA to a Roth IRA.

     The second section of this Kit contains our Universal IRA Disclosure
Statement.  The Disclosure Statement is divided into three parts:

     .    Part One describes the basic rules and benefits which are specifically
     applicable to your Regular IRA.

     .    Part Two describes the basic rules and benefits which are specifically
     applicable to your Roth IRA.

     .    Part Three describes important rules and information applicable to all
     IRAs.

     The third section of this Kit contains the Universal IRA Custodial
Agreement.  The Custodial Agreement is also divided into three parts:

     .  Part One contains provisions specifically applicable to Regular IRAs.

     .  Part Two contains provisions specifically applicable to Roth IRAs.

     .  Part Three contains provisions applicable to all IRAs (Regular and
     Roth).
          
<PAGE>
 
     This Universal Individual Retirement Custodial Account Kit contains
information and forms for both Regular IRAs and Roth IRAs.  However, you may use
the Adoption Agreement in this Kit to establish only one Regular IRA or one Roth
IRA; separate Adoption Agreements must be completed if you want to establish
multiple (Roth or Regular) IRA accounts.

WHAT'S THE DIFFERENCE BETWEEN A REGULAR IRA AND A ROTH IRA?

     With a Regular IRA, an individual can contribute up to $2,000 per year and
may be able to deduct the contribution from taxable income, reducing income
taxes. Taxes on investment growth and dividends are deferred until the money is
withdrawn.  Withdrawals are taxed as additional ordinary income when received.
Nondeductible contributions, if any, are withdrawn tax-free.  Withdrawals before
age 59 1/2 are assessed a 10% penalty in addition to income tax, unless an
exception applies.

     With a Roth IRA, the contribution limits are essentially the same as
Regular IRAs, but there is no tax deduction for contributions.  All dividends
and investment growth in the account are tax-free. Most important with a Roth
IRA:  there is NO INCOME TAX on qualified withdrawals from your Roth IRA.
Additionally, unlike a Regular IRA, there is no prohibition on making
contributions to Roth IRAs after turning age 70 1/2, and there's no requirement
that you begin making minimum withdrawals at that age.

     The following chart highlights some of the major differences between a
Regular IRA and a Roth IRA:

IS A ROTH OR A REGULAR IRA RIGHT FOR ME?

     We cannot act as your legal or tax advisor and so we cannot tell you which
kind of IRA is right for you. The information contained in this Kit is intended
to provide you with the basic information and material you will need if you
decide whether a Regular or Roth IRA is better for you, or if you want to
convert an existing Regular IRA to a Roth IRA. We suggest that you consult with
your accountant, lawyer or other tax advisor, or with a qualified financial
planner, to determine whether you should
<PAGE>
 
open a Regular or Roth IRA or convert any or all of an existing Regular IRA to a
Roth IRA.  Your tax advisor can also advise you as to the state tax consequences
that may affect whether a Regular or Roth IRA is right for you.

SEPS AND SIMPLES.

The State Street Bank Regular IRA may be used in connection with a simplified
employee pension (SEP) plan maintained by your employer.  To establish a Regular
IRA as part of your Employer's SEP plan, complete the Adoption Agreement for a
Regular IRA, indicating in the proper box that the IRA is part of a SEP plan.  A
Roth IRA should not be used in connection with a SEP plan.

A Roth IRA may NOT be used as part of an employer SIMPLE IRA plan.  A Regular
IRA may be used, but only after an individual has been participating for two or
more years (for the first two years, only a special SIMPLE IRA may be used).
SIMPLE IRA plans were added by the 1996 tax law to provide an easy and
inexpensive way for small employers to provide retirement benefits for their
employees.  If you are interested in a SIMPLE IRA plan at your place of
employment, call or write to the number or address given at the end of the
Disclosure Statement portion of this Kit.

OTHER POINTS TO NOTE.

     The Disclosure Statement in this Kit provides you with the basic
information that you should know about State Street Bank and Trust Company
Regular IRAs and Roth IRAs.  The Disclosure Statement provides general
information about the governing rules for these IRAs and the benefits and
features offered through each type of IRA.  However, the State Street Bank and
Trust Company Adoption Agreement and the Custodial Agreement, are the primary
documents controlling the terms and conditions of your personal State Street
Bank and Trust Company Regular or Roth IRA, and these shall govern in the case
of any difference with the Disclosure Statement.

     You or your when used throughout this Kit refer to the person for whom the
State Street Bank and Trust Company Regular or Roth IRA is established.  A Roth
IRA is either a State Street Bank and Trust Company Roth IRA or any Roth IRA
established by any other financial institution.  A Regular IRA is any non-Roth
IRA offered by State Street Bank and Trust Company or any other financial
institution.

               Universal Individual Retirement Custodial Account

             Instructions for Opening Your Regular IRA or Roth IRA

1.   Read carefully the applicable sections of the Universal IRA Disclosure
     Statement contained in this Kit, the Regular or Roth Individual Retirement
     Custodial Account document (as applicable), the Adoption Agreement, and the
     prospectus(es) for any Fund(s) you are considering.  Consult your lawyer or
     other tax adviser if you have any questions about how opening a Regular IRA
     or Roth IRA will affect your financial and tax situation.

     This Universal Individual Retirement Custodial Account Kit contains
     information and forms for both Regular IRAs and Roth IRAs. However, you may
     use the Adoption Agreement to establish only one Regular IRA or one Roth
     IRA; separate Adoption Agreements must be completed if you want to
     establish multiple (Roth or Regular) IRA accounts.

2.   Complete the Adoption Agreement

     -    Print the identifying information where requested in Part 1 of the
          Adoption Agreement.

     -    For a REGULAR IRA, check the box for Part A and check the other boxes
          in Part A to specify the type of Regular IRA you are opening and
          provide the registered information.

          If this is an IRA to which you expect to make contributions each year,
          check Box 1 and enclose a check in the amount of your first
          contribution. Be sure to indicate whether this is a contribution for
          last year or for the current year.

          If this is a transfer directly from another IRA custodian or trustee,
          check Box 2. Check the appropriate box to indicate whether the funds
          transferred were originally from contributions to an employee
          qualified plan or a 403(b) arrangement, or whether any of the funds
          were originally from your annual contributions to the IRA. Complete
          and sign the Universal IRA Transfer of Assets Form.

          If this is a rollover of amounts distributed to you from another IRA
          or an employer qualified plan or a 403(b) arrangement, check Box 3.
          Check the appropriate box to indicate whether the transfer is coming
          from a qualified plan or 403(b) arrangement, or an IRA that held only
          funds that were originally from contributions to a qualified plan or
          403(b), or whether any of the funds were originally from your annual
          contributions to the IRA. Enclose a check for the rollover
          contribution amount.

          If this is a direct rollover from a qualified plan or 403(b)
          arrangement, check Box 4. Complete and sign the Universal IRA Transfer
          of Assets Form.

          Check Box 5 if applicable (for an IRA that will be used to receive
          employer contributions under an employer's simplified employee pension
          (or "SEP") plan or under a grandfathered salary reduction SEP plan (or
          "SARSEP")).

     -    For a ROTH IRA, check the box for Part B.  Check the other boxes in
          Part B to specify the type of Roth IRA you are opening and provide the
          requested information.

          If this is a Roth IRA to which you expect to make contributions each
          year, enclose a check in the amount of your first contribution. Be
          sure to indicate whether this is a contribution for last year or for
          the current year. Only annual contributions may be accepted in an
          annual contribution Roth
<PAGE>
 
          IRA account. NOTE: Roth IRAs are available starting January 1, 1998,
          so you cannot make a contribution for 1997.

          If you are converting an existing Regular IRA with the Bank as IRA
          custodian or trustee, check Box 2. Indicate your current IRA account
          number and how much you are converting. Conversion of an existing
          Regular IRA will result in inclusion of taxable amounts in the
          existing Regular IRA on your income tax return. NOTE: If a conversion,
          rollover or transfer from a Regular IRA to a Roth IRA is being made,
          only amounts converted, rolled over or transferred during the same tax
          year will be accepted in a single Roth IRA. A separate Roth IRA must
          be established to hold such amounts from a different tax year. Annual
          contributions may never be deposited in a Roth IRA holding such
          converted, rolled over or transferred amounts.

          If you are making a rollover or a transfer from an existing Regular
          IRA with a different custodian or trustee, check Box 3. A rollover or
          transfer from an existing Regular IRA means that the taxable amount in
          the existing Regular IRA will be treated as additional income on your
          income tax return.

          If you are making a rollover or a transfer from another Roth IRA with
          a different trustee or custodian, check Box 4. Put the requested
          information where indicated.

     -    In Part 3, indicate your investment choices.

     -    In Part 4, indicate your Primary and Alternate Beneficiaries.
          (Spousal waiver must be signed if beneficiary is spouse.)

     -    Sign and date the Adoption Agreement in Part 5 at the end.

3.   If you are transferring assets from an existing  IRA to this IRA, complete
     the Universal Transfer of Assets Form.

     .  Regular IRA*      .  SEP IRA*     .  Roth IRA**  .  SIMPLE IRA***
        
*       You may not transfer from a Roth IRA to a Regular IRA or a simplified
        employee pension (SEP) IRA. Transfers to a Regular IRA or SEP IRA may be
        made from another Regular IRA or SEP IRA, qualified employer plan,
        403(b) arrangement, or a simple IRA account (but not until at least 2
        years after the first contribution to your simple IRA account).
        
**      Transfers to a Roth IRA are possible only from another Roth IRA or from
        a Regular IRA, not from other types of tax-deferred accounts. A transfer
        from a Regular IRA will trigger federal income tax on the taxable amount
        transferred from the Regular IRA. Note: If a conversion, rollover or
        transfer from a Regular IRA to a Roth IRA is being made, only amounts
        converted, rolled over or transferred during the same tax year will be
        accepted in a single Roth IRA. A separate Roth IRA must be established
        to hold such amounts from a different tax year. Annual contributions may
        not be deposited in a Roth IRA holding such converted, rolled over or
        transferred amounts.
        
***     Transfers to a SIMPLE IRA may be made only from another SIMPLE IRA.
        During the first two years after a SIMPLE IRA is established, transfers
        may be made only to another SIMPLE IRA; after two years, transfers may
        be made from a SIMPLE IRA to a Regular IRA.

                     -------------------------------------

SPECIAL NOTE

     Part One of the Disclosure Statement describes the rules applicable to
Regular IRAs beginning January 1, 1998. IRAs described in these pages are called
"Regular IRAs" to distinguish them from the new "Roth IRAs" first available
starting in 1998. Roth IRAs are described in Part Two of this Disclosure
Statement.

     For Regular IRA contributions for 1997 (including contributions made up to
April 15, 1998 but designated as contributions for 1997), there are different
rules for determining the deductibility of your contribution on your federal tax
return.  For contributions for 1997, the "active participant" limits on
deductibility (described below) apply if either spouse is an active participant
                                         ------                                
in an employer-sponsored plan. Also, the adjusted gross income ("AGI") levels
for partially deductible or nondeductible Regular IRA contributions (described
below) are lower for 1997 ($25,000 for single taxpayers, with no deduction if
your AGI is above $35,000; and $40,000 for married taxpayers filing jointly,
with no deduction if your AGI is above $50,000).  Also, the exceptions to the
10% early withdrawal penalty for withdrawals to pay   certain higher education
or first-time homebuyer expenses do not apply to withdrawals in 1997.

     This Part One of the Disclosure Statement describes Regular IRAs. It does
not describe Roth IRAs, a new type of IRA available starting in 1998.
Contributions to a Roth IRA are not deductible (regardless of your AGI), but
withdrawals that meet certain requirements are not subject to federal income
tax, so that dividends and investment growth on amounts held in the Roth IRA can
escape federal income tax. Please see Part Two of this Disclosure Statement if
you are interested in learning more about Roth IRAs.

     Regular IRAs described in this Disclosure Statement may be used as part of
a simplified employee pension (SEP) plan maintained by your employer. Under a
SEP your employer may make contributions to your Regular IRA, and these
contributions may exceed the normal limits on Regular IRA contributions. This
Disclosure Statement does not describe IRAs established in connection with a
SIMPLE IRA program maintained by your employer. Employers provide special
explanatory materials for accounts established as part of a SIMPLE IRA program.
Regular IRAs may be used in connection with a SIMPLE IRA program, but for the
first two years of participation a special SIMPLE IRA (not a Regular IRA) is
required.

YOUR REGULAR IRA

     This Part One contains information about your Regular Individual Retirement
Custodial Account with State Street Bank and Trust Company as Custodian.  A
Regular IRA gives you several tax benefits.  Earnings on the assets held in your
Regular IRA are not subject to federal income tax until withdrawn by you.  You
may be able to deduct all or part of your Regular IRA contribution on your
federal income tax return.  State income tax treatment of your Regular IRA may
differ from federal treatment; ask your state tax department or your personal
tax advisor for details.

     Be sure to read Part Three of this Disclosure Statement for important
additional information, including information on how to revoke your Regular IRA,
investments and prohibited transactions, fees and expenses, and certain tax
requirements.

ELIGIBILITY

WHAT ARE THE ELIGIBILITY REQUIREMENTS FOR A REGULAR IRA?

     You are eligible to establish and contribute to a Regular IRA for a year
if:

     -    You received compensation (or earned income if you are self employed)
     during the year for personal services you rendered. If you received taxable
     alimony, this is treated like compensation for IRA purposes.

     -    You did not reach age 702 during the year.

CAN I CONTRIBUTE TO A REGULAR IRA FOR MY SPOUSE?

   For each year before the year when your spouse attains age 702, you can
contribute to a separate Regular IRA for your spouse, regardless of whether your
spouse had any compensation or earned income in that year.  This is called a
"spousal IRA."  To make a contribution to a Regular  IRA for your spouse, you
must file a joint tax return for the year with your spouse.  For a spousal IRA,
your spouse must set up a different Regular IRA, separate from yours, to which
you contribute.

CONTRIBUTIONS

WHEN CAN I MAKE CONTRIBUTIONS TO A REGULAR IRA?

   You may make a contribution to your existing Regular IRA or establish a new
Regular IRA for a taxable year by the due date (not including any extensions)
                                                ---                          
for your federal income tax return for the year.  Usually this is April 15 of
the following year.

HOW MUCH CAN I CONTRIBUTE TO MY REGULAR IRA?

     For each year when you are eligible (see above), you can contribute up to
the lesser of $2,000 or 100% of your compensation (or earned income, if you are
self-employed). However, under the tax laws, all or a portion of your
contribution may not be deductible.

     If you and your spouse have spousal Regular IRAs, each spouse may
contribute up to $2,000 to his or her IRA for a year as long as the combined
compensation of both spouses for the year (as shown on your joint income tax
return) is at least $4,000. If the combined compensation of both spouses is less
than $4,000, the spouse with the higher amount of compensation may contribute up
to that spouse's compensation amount, or $2,000 if less. The spouse with the
<PAGE>
 
lower compensation amount may contribute any amount up to that spouse's
compensation plus any excess of the other spouse's compensation over the other
spouse's IRA contribution. However, the maximum contribution to either spouse's
Regular IRA is $2,000 for the year.

     If you (or your spouse) establish a new Roth IRA and make contributions to
both your Regular IRA and a Roth IRA, the combined limit on contributions to
both your (or your spouse's) Regular IRA and Roth IRA for a single calendar year
is $2,000.

HOW DO I KNOW IF MY CONTRIBUTION IS TAX DEDUCTIBLE?

     The deductibility of your contribution depends upon whether you are  an
active participant in any employer-sponsored retirement plan.  If you are not an
active participant, the entire  contribution to your Regular IRA is deductible.

     If you are an active participant in an employer-sponsored plan, your
Regular IRA contribution may still be completely or partly deductible on your
tax return. This depends on the amount of your income (see below).

     Similarly, the deductibility of a contribution to a Regular IRA for your
spouse depends upon whether your spouse is an active participant in any
employer-sponsored retirement plan.  If your spouse is not an active
participant, the contribution to your spouse's Regular IRA will be deductible.
If your spouse is an active participant, the Regular IRA contribution will be
completely, partly or not deductible depending upon your combined income.

     An exception to the preceding rules applies to high-income married
taxpayers, where one spouse is an active participant in an employer-sponsored
retirement plan and the other spouse is not. A contribution to the non-active
participant spouse's Regular IRA will be only partly deductible at an adjusted
gross income level on the joint tax return of $150,000, and the deductibility
will be phased out as described below over the next $10,000 so that there will
be no deduction at all with an adjusted gross income level of $160,000 or
higher.

HOW DO I DETERMINE MY OR MY SPOUSE'S "ACTIVE PARTICIPANT" STATUS?

     Your (or your spouse's) Form W-2 should indicate if you (or your spouse)
were an active participant in an employer-sponsored retirement plan for a year.
If you have a question, you should ask your employer or the plan administrator.

     In addition, regardless of income level, your spouse's "active participant"
status will not affect the deductibility of your contributions to your Regular
IRA if you and your spouse file separate tax returns for the taxable year and
you lived apart at all times during the taxable year.

WHAT ARE THE DEDUCTION RESTRICTIONS FOR ACTIVE PARTICIPANTS?

     If you (or your spouse) are an active participant in an employer plan
during a year, the contribution to your Regular IRA (or your spouse's Regular
IRA) may be completely, partly or not deductible depending upon your filing
status and your amount of adjusted gross income ("AGI").  If AGI is any amount
up to the lower limit, the contribution is deductible.  If your AGI falls
between the lower limit and the upper limit, the contribution is partly
deductible.  If your AGI falls above the upper limit, the contribution is not
deductible.

</TABLE>

HOW DO I CALCULATE MY DEDUCTION IF I FALL IN THE "PARTLY DEDUCTIBLE" RANGE?

          If your AGI falls in the partly deductible range, you must calculate
the portion of your contribution that is deductible. To do this, multiply your
contribution by a fraction. The numerator is the amount by which your AGI
exceeds the lower limit (for 1998: $30,000 if single, or $50,000 if married
filing jointly). The denominator is $10,000 (note that the denominator for
married joint filers is $20,000 starting in 2007). Subtract this from your
contribution and then round down to the nearest $10. The deductible amount is
the greater of the amount calculated or $200 (provided you contributed at least
$200). If your contribution was less than $200, then the entire contribution is
deductible.

          For example, assume that you make a $2,000 contribution to your
Regular IRA in 1998, a year in which you are an active participant in your
employer's retirement plan. Also assume that your AGI is $57,555 and you are
married, filing jointly. You would calculate the deductible portion of your
contribution this way:

1.   The amount by which your AGI exceeds the lower limit of the partly -
     deductible range:
                                ($57,555-$50,000) = $7,555

2.   Divide this by $10,000:  $ 7,555   = 0.7555
                               ------           
                              $10,000

3.   Multiply this by your contribution limit:
           0.7555 x $2,000 = $1,511

4.   Subtract this from your contribution:
           ($2,000 - $1,551) = $489

5.   Round this down to the nearest $10: = $480

6.   Your deductible contribution is the greater of this amount or $200.

Even though part or all of your contribution is not deductible, you may still
contribute to your Regular IRA (and your spouse may contribute to your spouse's
Regular IRA) up to the limit on contributions.  When you file your tax return
for the year, you must designate the amount of non-deductible  contributions to
your Regular IRA for the year.  See IRS Form 8606.

HOW DO I DETERMINE MY AGI?

          AGI is your gross income minus those deductions which are available to
all taxpayers even if they don't itemize.  Instructions to calculate your AGI
are provided with your income tax Form 1040 or 1040A.

WHAT HAPPENS IF I CONTRIBUTE MORE THAN ALLOWED TO MY REGULAR IRA?

          The maximum contribution you can make to a Regular  IRA generally is
$2,000 or 100% of compensation or earned income, whichever is less.  Any amount
contributed to the IRA above the maximum is considered an "excess contribution."
The excess is calculated using your contribution limit, not the deductible
                                    ------------                ----------
limit.  An excess contribution is subject to excise tax of 6% for each year it
remains in the IRA.

HOW CAN I CORRECT AN EXCESS CONTRIBUTION?

          Excess contributions may be corrected without paying a 6% penalty. To
do so, you must withdraw the excess and any earnings on the excess before the
due date (including extensions) for filing your federal income tax return for
the year for which
<PAGE>
 
you made the excess contribution. A deduction should not be taken for any excess
contribution. Earnings on the amount withdrawn must also be withdrawn. The
earnings must be included in your income for the tax year for which the
contribution was made and may be subject to a 10% premature withdrawal tax if
you have not reached age 592.

WHAT HAPPENS IF I DON'T CORRECT THE EXCESS CONTRIBUTION BY THE TAX RETURN DUE
DATE?

       Any excess contribution withdrawn after the tax return due date
(including any extensions) for the  year for which the contribution was made
will be subject to the 6% excise tax.  There will be an additional 6% excise tax
for each year the excess remains in your account.

       Under limited circumstances, you may correct an excess contribution after
tax filing time by withdrawing the excess contribution (leaving the earnings in
the account).  This withdrawal will not be includable in income nor will it be
subject to any premature withdrawal penalty if (1) your contributions to all
Regular IRAs do not exceed $2,000 and (2) you did not take a deduction for the
excess amount (or you file an amended return (Form 1040X) which removes the
excess deduction).

HOW ARE EXCESS CONTRIBUTIONS TREATED IF NONE OF THE PRECEDING RULES APPLY?

       Unless an excess contribution qualifies for the special treatment
outlined above, the excess contribution and any earnings on it withdrawn after
tax filing time will be includable in taxable income and may be subject to a 10%
premature withdrawal penalty.  No deduction will be allowed for the excess
contribution for the year in which it is made.

       Excess contributions may be corrected in a subsequent year to the extent
that you contribute less than your maximum amount.  As the prior excess
contribution is reduced or eliminated, the 6% excise tax will become
correspondingly reduced or eliminated for subsequent tax years.  Also, you may
be able to take an income tax deduction for the amount of excess that was
reduced or eliminated, depending on whether you would be able to take a
deduction if you had instead contributed the same amount.

ARE THE EARNINGS ON MY REGULAR IRA FUNDS TAXED?

       Any dividends on or growth of the investments held in your Regular IRA
are generally exempt from federal income taxes and will not be taxed until
withdrawn by you, unless the tax exempt status of your Regular IRA is revoked
(this is described in Part Three of this Disclosure Statement).

TRANSFERS/ROLLOVERS

CAN I TRANSFER OR ROLL OVER A DISTRIBUTION I RECEIVE FROM MY EMPLOYER'S
RETIREMENT PLAN INTO A REGULAR IRA?

       Almost all distributions from employer plans or 403(b) arrangements (for
employees of tax-exempt employers) are eligible for rollover to a Regular IRA.
The main exceptions are

          .  payments over the lifetime or life expectancy of the participant
       (or participant and a designated beneficiary),

          .  installment payments for a period of 10 years or more,

          .  required distributions (generally the rules require distributions
       starting at age 702 or for certain employees starting at retirement, if
       later), and

          .  payments of employee after-tax contributions.

If you are eligible to receive a distribution from a tax qualified retirement
plan as a result of, for example, termination of employment, plan
discontinuance, or retirement, all or part of the distribution may be
transferred directly into your Regular IRA.  This is a called a "direct
rollover."  Or, you may receive the distribution and make a regular rollover to
your Regular IRA within 60 days.  By making a direct rollover or a regular
rollover, you can defer income taxes on the amount rolled over until you
subsequently make withdrawals from your IRA.

          The maximum amount you may roll over is the amount of employer
contributions and earnings distributed.  You may not roll over any after-tax
employee contributions you made to the employer retirement plan.  If you are
over age 702 and are required to take minimum distributions under the tax laws,
you may not roll over any amount required to be distributed to you under the
minimum distribution rules.  Also, if you are receiving periodic payments over
your or your and your designated beneficiary's life expectancy or for a period
of at least 10 years, you may not roll over these payments.  A rollover to a
regular  IRA must be completed within 60 days after the distribution from the
employer retirement plan to be valid.

          NOTE:  A qualified plan administrator or 403(b) sponsor MUST WITHHOLD
20% OF YOUR DISTRIBUTION for federal income taxes UNLESS you elect a direct
rollover. Your plan or 403(b) sponsor is required to provide you with
information about direct and traditional rollovers and withholding taxes before
you receive your distribution and must comply with your directions to make a
direct rollover.

          The rules governing rollovers are complicated. Be sure to consult your
tax advisor or the IRS if you have a question about rollovers.

ONCE I HAVE ROLLED OVER A PLAN DISTRIBUTION INTO A REGULAR IRA, CAN I
SUBSEQUENTLY ROLL OVER INTO ANOTHER EMPLOYER'S QUALIFIED RETIREMENT PLAN?

       Yes.  Part or all of an eligible distribution received from a qualified
plan may be transferred from the Regular IRA holding it to another qualified
plan.  However, the IRA must have no assets other than those which were
previously distributed to you from the qualified plan.  Specifically, the IRA
cannot contain any contributions by you (or your spouse).  Also, the new
qualified plan must accept rollovers.  Similar rules apply to Regular IRAs
established with rollovers from 403(b) arrangements.

CAN I MAKE A TRADITIONAL ROLLOVER FROM MY REGULAR IRA TO ANOTHER REGULAR IRA?

       You may make a rollover from one Regular IRA to another Regular IRA you
have or you establish to receive the rollover.  Such a rollover must be
completed within 60 days after the withdrawal from your first Regular IRA.
After making a traditional rollover from one Regular IRA to another, you must
wait a full year (365 days) before you can make another such rollover.
(However, you can instruct a Regular IRA custodian to 
<PAGE>
 
transfer amounts directly to another Regular IRA custodian; such a direct
transfer does not count as a rollover.)

WHAT HAPPENS IF I COMBINE ROLLOVER CONTRIBUTIONS WITH MY NORMAL CONTRIBUTIONS IN
ONE IRA?

       If you wish to make both a normal annual contribution and a rollover
contribution, you may wish to open two separate Regular IRAs by completing two
Adoption Agreements and two sets of forms.  You should consult a tax advisor
before making your annual contribution to the IRA you established with rollover
contributions (or make a rollover contribution to the IRA to which you make your
annual contributions).  This is because combining your annual contributions and
rollover contributions originating from an employer plan distribution would
prohibit the future rollover out of the IRA into another qualified plan.  If
despite this, you still wish to combine a rollover contribution and the IRA
holding your annual contributions, you should establish the account as a Regular
IRA on the Adoption Agreement (not a Rollover IRA or Direct Rollover IRA) and
make the contributions to that account.

HOW DO ROLLOVERS AFFECT MY CONTRIBUTION OR DEDUCTION LIMITS?

       Rollover contributions, if properly made, do not count toward the maximum
contribution.  Also, rollovers are not deductible and they do not affect your
deduction limits as described above.

WHAT ABOUT CONVERTING MY REGULAR IRA TO A ROTH IRA?

       The rules for converting a Regular IRA to a new Roth IRA, or making a
rollover from a Regular IRA to a new Roth IRA, are described in Part Two below.

WITHDRAWALS

WHEN CAN I MAKE WITHDRAWALS FROM MY REGULAR IRA?

       You may withdraw from your Regular IRA at any time.  However, withdrawals
before age 592 may be subject to a 10% penalty tax in addition to regular income
taxes (see below).

WHEN MUST I START MAKING WITHDRAWALS?

       If you have not withdrawn your entire IRA by the April 1 following the
year in which you reach 702, you must make minimum withdrawals in order to avoid
penalty taxes.  The rule allowing certain employees to postpone distributions
from an employer qualified plan until actual retirement (even if this is after
age 702) does not apply to Regular IRAs.
              ---                       

       The minimum withdrawal amount is determined by dividing the balance in
your Regular IRA (or IRAs) by your life expectancy or the combined life
expectancy of you and your designated beneficiary.  The minimum withdrawal rules
are complex.  Consult your tax advisor for assistance.

       The penalty tax is 50% of the difference between the minimum withdrawal
amount and your actual withdrawals during a year.  The IRS may waive or reduce
the penalty tax if you can show that your failure to make the required minimum
withdrawals was due to reasonable cause and you are taking reasonable steps to
remedy the problem.

HOW ARE WITHDRAWALS FROM MY REGULAR IRA TAXED?

       Amounts withdrawn by you are includable in your gross income in the
taxable year that you receive them, and are taxable as ordinary income.  Lump
sum withdrawals from a Regular IRA are not eligible for averaging treatment
currently available to certain lump sum distributions from qualified employer
retirement plans.

       Since the purpose of a Regular IRA is to accumulate funds for retirement,
your receipt or use of any portion of your Regular IRA before you attain age 592
generally will be considered as an early withdrawal and subject to a 10% penalty
tax.

       The 10% penalty tax for early withdrawal will not apply if:

  -    The distribution was a result of your death or
       disability.

  -    The purpose of the withdrawal is to pay certain higher education expenses
       for yourself or your spouse, child, or grandchild. Qualifying expenses
       include tuition, fees, books, supplies and equipment required for
       attendance at a post-secondary educational institution. Room and board
       expenses may qualify if the student is attending at least half-time.

  -    The withdrawal is used to pay eligible first-time homebuyer expenses.
       These are the costs of purchasing, building or rebuilding a principal
       residence (including customary settlement, financing or closing costs).
       The purchaser may be you, your spouse, or a child, grandchild, parent or
       grandparent of you or your spouse. An individual is considered a "first-
       time homebuyer" if the individual (or the individual's spouse, if
       married) did not have an ownership interest in a principal residence
       during the two-year period immediately preceding the acquisition in
       question. The withdrawal must be used for eligible expenses within 120
       days after the withdrawal. (If there is an unexpected delay, or
       cancellation of the home acquisition, a withdrawal may be redeposited as
       a rollover).

       There is a lifetime limit on eligible first-time homebuyer expenses of
       $10,000 per individual.

       -       The distribution is one of a scheduled series of substantially
       equal periodic payments for your life or life expectancy (or the joint
       lives or life expectancies of you and your beneficiary).

               If there is an adjustment to the scheduled series of payments,
       the 10% penalty tax may apply. The 10% penalty will not apply if you make
       no change in the series of payments until the end of five years or until
       you reach age 59 1/2, whichever is later. If you make a change before
       then, the penalty will apply. For example, if you begin receiving
       payments at age 50 under a withdrawal program providing for substantially
       equal payments over your life expectancy, and at age 58 you elect to
       receive the remaining amount in your Regular IRA in a lump-sum, the 10%
       penalty tax will apply to the lump sum and to the amounts previously paid
       to you before age 59.
<PAGE>
 
     -    The distribution does not exceed the amount of your deductible medical
     expenses for the year (generally speaking, medical expenses paid during a
     year are deductible if they are greater than 72% of your adjusted gross
     income for that year).

     -    The distribution does not exceed the amount you paid for health
     insurance coverage for yourself, your spouse and dependents. This exception
     applies only if you have been unemployed and received federal or state
     unemployment compensation payments for at least 12 weeks; this exception
     applies to distributions during the year in which you received the
     unemployment compensation and during the following year, but not to any
     distributions received after you have been reemployed for at least 60 days.

HOW ARE NONDEDUCTIBLE CONTRIBUTIONS TAXED WHEN THEY ARE WITHDRAWN?

     A withdrawal of nondeductible contributions (not including earnings) will
be tax-free. However, if you made both deductible and nondeductible
contributions to your Regular IRA, then each distribution will be treated as
partly a return of your nondeductible contributions (not taxable) and partly a
distribution of deductible contributions and earnings (taxable). The nontaxable
amount is the portion of the amount withdrawn which bears the same ratio as your
total nondeductible Regular IRA contributions bear to the total balance of all
your Regular IRAs (including rollover IRAs and SEPs, but not including Roth
IRAs).

     For example, assume that you made the following Regular IRA contributions:

<TABLE>
<CAPTION>

     Year      Deductible  Nondeductible
     ----      ----------  -------------
     <S>       <C>         <C>
     1995        $2,000
     1996        $2,000
     1997        $1,000         $1,000
     1998                       $1,000
                 ------         ------
                 $5,000         $2,000
</TABLE>

     In addition assume that your Regular IRA has total investment earnings
through 1998 of $1,000.  During 1998 you withdraw $500.  Your total account
balance as of 12-31-98 is $7,500 as shown below.

<TABLE>
<S>                                     <C>
Deductible Contributions                $5,000
Nondeductible Contributions             $2,000
Earnings On IRA                         $1,000
Less 1998 Withdrawal                    $  500
                                        ------
Total Account Balance as of 12/31/98    $7,500
</TABLE>

     To determine the nontaxable portion of your 1998 withdrawal, the total 1998
withdrawal ($500) must be multiplied by a fraction. The numerator of the
fraction is the total of all nondeductible contributions remaining in the
account before the 1998 withdrawal ($2,000). The denominator is the total
account balance as of 12-31-98 ($7,500) plus the 1998 withdrawal ($500) or
$8,000. The calculation is:

                   Total Remaining
             Nondeductible Contributions  $2,000 x $500  =  $  125
             ---------------------------  ------                  
              Total Account Balance       $8,000

     Thus, $125 of the $500 withdrawal in 1998 will not be included in your
taxable income.  The remaining $375 will be taxable for 1998.  In addition, for
future calculations the remaining nondeductible contribution total will be
$2,000 minus $125, or $1,875.

      A loss in your Regular IRA investment may be deductible. You should
consult your tax advisor for further details on the appropriate calculation for
this deduction if applicable.

IS THERE A PENALTY TAX ON CERTAIN LARGE WITHDRAWALS OR ACCUMULATIONS IN MY IRA?

     Earlier tax laws imposed a "success" penalty equal to 15% of withdrawals
from all retirement accounts (including IRAs, 401(k) or other employer
retirement plans, 403(b) arrangements and others) in a year exceeding a
specified amount (initially $150,000 per year). Also, there was a 15% estate tax
penalty on excess accumulations remaining in IRAs and other tax-favored
arrangements upon your death. These 15% penalty taxes have been repealed.
                                                                --------

IMPORTANT:  Please see Part Three below which contains important information

applicable to all State Street Bank and Trust Company IRAs.

                      PART TWO: DESCRIPTION OF ROTH IRAS
                      ----------------------------------

SPECIAL NOTE

     Part Two of the Disclosure Statement describes the rules generally
applicable to Roth IRAs beginning January 1, 1998.

     Roth IRAs are a new kind of IRA available for the first time in 1998.
Contributions to a Roth IRA for 1997 are not permitted.  Contributions to a Roth
                                         ---                                    
IRA are not tax-deductible, but withdrawals that meet certain requirements are
not subject to federal income taxes.  This makes the dividends on and growth of
the investments held in your Roth IRA tax-free for federal income tax purposes
if the requirements are met.

     Regular IRAs, which have existed since 1975, are still available.
Contributions to a Regular IRA may be tax-deductible. Earnings and gains on
amounts while held in a Regular IRA are tax-deferred. Withdrawals are subject to
federal income tax (except for prior after-tax contributions which may be
recovered without additional federal income tax).

     This Part Two does not describe Regular IRAs. If you wish to review
information about Regular IRAs, please see Part One of this Disclosure
Statement.

     This Disclosure Statement also does not describe IRAs established in
connection with a SIMPLE IRA program or a Simplified Employee Pension (SEP) plan
maintained by your employer.  Roth IRAs may not be used in connection with a
SIMPLE IRA program or a SEP plan.

YOUR ROTH IRA

     Your Roth IRA gives you several tax benefits. While contributions to a Roth
IRA are not deductible, dividends on and growth of the assets held in your Roth
IRA are not subject to federal income tax. Withdrawals by you from your Roth IRA
are excluded from your income for federal income tax purposes if certain
requirements (described below) are met. State income tax treatment of your Roth
IRA may differ from federal treatment; ask your state tax department or your
personal tax advisor for details.

Be sure to read Part Three of this Disclosure Statement for important additional
information, including information on how to revoke your Roth IRA, investments
and prohibited transactions, fees and expenses and certain tax requirements.

ELIGIBILITY

WHAT ARE THE ELIGIBILITY REQUIREMENTS FOR A ROTH IRA?

     Starting with 1998, you are eligible to establish and contribute to a Roth
IRA for a year if you received compensation (or earned income if you are self
employed) during the year for personal services you rendered. If you received
taxable alimony, this is treated like compensation for IRA purposes.

     In contrast to a Regular IRA, with a Roth IRA you may continue making
contributions after you reach age 70 1/2.

CAN I CONTRIBUTE TO ROTH  IRA FOR MY SPOUSE?

     Starting with 1998, if you meet the eligibility requirements you can not
only contribute to your own Roth IRA, but also to a separate Roth IRA for your
spouse out of your compensation or earned income, regardless of whether your
spouse had any compensation or earned income in that year. This is called a
"spousal Roth IRA." To make a contribution to a Roth IRA for your spouse, you
must file a joint tax return for the year with your spouse. For a spousal Roth
IRA, your spouse must set up a different Roth IRA, separate from yours, to which
you contribute.

     Of course, if your spouse has compensation or earned income, your spouse
can establish his or her own Roth IRA and make contributions to it in accordance
with the rules and limits described in this Part Two of the Disclosure
Statement.

CONTRIBUTIONS

WHEN CAN I MAKE CONTRIBUTIONS TO A ROTH IRA?

     You may make a contribution to your Roth IRA or establish a new Roth IRA
for a taxable year by the due date (not including any extensions) for your
                                    ---
federal income tax return for the year. Usually this is April 15 of the
following year. For example, you will have until April 15, 1999 to establish and
make a contribution to a Roth IRA for 1998.

     Caution:  Since Roth IRAs are available starting January 1, 1998, you may
not make a contribution by April 15, 1998 to a Roth IRA for 1997.

HOW MUCH CAN I CONTRIBUTE TO MY ROTH IRA?

     For each year when you are eligible (see above), you can contribute up to
the lesser of $2,000 or 100% of your compensation (or earned income, if you are
self-employed).

     Annual contributions may be made only to a Roth IRA annual contribution
account which does not contain converted or transferred funds from a Regular
IRA.

     Your Roth IRA limit is reduced by any contributions for the same year to a
Regular IRA.  For example, assuming you have at least $2,000 in compensation or
earned income, if you contribute $500  to your Regular IRA for 1998, your
maximum Roth IRA contribution for 1998 will be $1,500.

     If you and your spouse have spousal Roth IRAs, each spouse may contribute
up to $2,000 to his or her Roth IRA for a year as long as the combined
compensation of both spouses for the year (as shown on your joint income tax
return) is at least $4,000. If the combined compensation of both spouses is less
than $4,000, the spouse with the higher amount of compensation may contribute up
to that spouse's compensation amount, or $2,000 if less. The spouse with the
lower compensation amount may contribute any amount up to that spouse's
compensation plus any excess the other spouse's compensation over the other
spouse's Roth IRA contribution. However, the maximum contribution to either
spouse's Roth IRA is $2,000 for the year.
<PAGE>
 
     As noted above, the spousal Roth IRA limits are reduced by any
contributions for the same calendar year to a Regular IRA maintained by you or
your spouse.

     For taxpayers with high income levels, the contribution limits may be
reduced (see below).

ARE CONTRIBUTIONS TO A ROTH IRA TAX DEDUCTIBLE?

     Contributions to a Roth IRA are not deductible.  This is a major difference
                                     ---                                        
between Roth IRAs and Regular IRAs. Contributions to a Regular IRA may be
deductible on your federal income tax return depending on whether or not you are
an active participant in an employer-sponsored plan and on your income level.
 
ARE THE EARNINGS ON MY ROTH IRA FUNDS TAXED?

     Any dividends on or growth of investments held in your Roth IRA are
generally exempt from federal income taxes and will not be taxed until withdrawn
by you, unless the tax exempt status of your Roth IRA is revoked. If the
withdrawal qualifies as a tax-free withdrawal (see below), amounts reflecting
earnings or growth of assets in your Roth IRA will not be subject to federal
income tax.

WHICH IS BETTER, A ROTH IRA OR A REGULAR IRA?

     This will depend upon your individual situation.  A Roth IRA may be better
if you are an active participant in an employer-sponsored plan and your adjusted
gross income is too high to make a deductible IRA contribution (but not too high
to make a Roth IRA contribution).  Also, the benefits of a Roth IRA vs. a
Regular IRA may depend upon a number of other factors including:  your current
income tax bracket vs. your expected income tax bracket when you make
withdrawals from your IRA, whether you expect to be able to make nontaxable
withdrawals from your Roth IRA (see below), how long you expect to leave your
contributions in the IRA, how much you expect the IRA to earn in the meantime,
and possible future tax law changes.

     Consult a qualified tax or financial advisor for assistance on this
question.

ARE THERE ANY RESTRICTIONS ON CONTRIBUTIONS TO MY ROTH IRA?

     Taxpayers with very high income levels may not be able to contribute to a
Roth IRA at all, or their contribution may be limited to an amount less than
$2,000. This depends upon your filing status and the amount of your adjusted
gross income (AGI). The following table shows how the contribution limits are
restricted:

</TABLE>

     Note:  If you are a married taxpayer filing separately, your maximum Roth
IRA contribution limit phases out over the first $15,000 of adjusted gross
income. If your AGI is $15,000 or more you may not contribute to a Roth IRA for
the year. (Note: Pending legislation in Congress may reduce this number from
$15,000 to $10,000. Consult your tax advisor or the IRS for the latest
developments.)

HOW DO I CALCULATE MY LIMIT IF I FALL IN THE "REDUCED CONTRIBUTION" RANGE?

     If your AGI falls in the reduced contribution range, you must calculate
your contribution limit. To do this, multiply your normal contribution limit
($2,000 or your compensation if less) by a fraction. The numerator is the amount
by which your AGI exceeds the lower limit of the reduced contribution range
($95,000 if single, or $150,000 if married filing jointly). The denominator is
$15,000 (single taxpayers) or $10,000 (married filing jointly). Subtract this
from your normal limit and then round down to the nearest $10. The contribution
limit is the greater of the amount calculated or $200.

     For example, assume that your AGI for the year is $157,555 and you are
married, filing jointly.  You would calculate your Roth IRA contribution limit
this way:

1.   The amount by which your AGI exceeds the lower limit of the reduced
     contribution deductible range:
                                   ($157,555-$150,000) = $7,555

2.   Divide this by $10,000:                    $7,555
                                               -------
                                               $10,000 =  0.7555

3.   Multiply this by $2,000 (or your compensation for the year, if less):

                  0.7555 x $2,000 = $1,511

4.   Subtract this from your $2,000 limit:

                  ($2,000 - $1,551) = $489

5.   Round this down to the nearest $10 = $480
<PAGE>
 
6. Your contribution limit is the greater of this amount or $200.

     Remember, your Roth IRA contribution limit of $2,000 is reduced by any
contributions for the same year to a Regular IRA.  If you fall in the reduced
contribution range, the reduction formula applies to the Roth IRA contribution
limit left after subtracting your contribution for the year to a Regular IRA.

HOW DO I DETERMINE MY AGI?

     AGI is your gross income minus those deductions which are available to all
taxpayers even if they don't itemize. Instructions to calculate your AGI are
provided with your income tax Form 1040 or 1040A.

     There are two additional rules when calculating AGI for purposes of Roth
IRA contribution limits. First, if you are making a deductible contribution for
the year to a Regular IRA, your AGI is reduced by the amount of the deduction.
Second, if you are converting a Regular IRA to a Roth IRA in a year (see below),
the amount includable in your income as a result of the conversion is not
considered AGI when computing your Roth IRA contribution limit for the year.
(Note: a bill pending in Congress might affect the first rule -- consult your
tax advisor or the IRS for the latest developments.)

WHAT HAPPENS IF I CONTRIBUTE MORE THAN ALLOWED TO MY ROTH IRA?

     The maximum contribution you can make to a Roth IRA generally is $2,000 or
100% of compensation or earned income, whichever is less.  As noted above, your
maximum is reduced by the amount of any contribution to a Regular IRA for the
same year and may be further reduced if you have high AGI.  Any amount
contributed to the Roth IRA above the maximum is considered an "excess
contribution."

An excess contribution is subject to excise tax of 6% for each year it remains
in the Roth IRA.

HOW CAN I CORRECT AN EXCESS CONTRIBUTION?

     Excess contributions may be corrected without paying a 6% penalty. To do
so, you must withdraw the excess and any earnings on the excess before the due
date (including extensions) for filing your federal income tax return for the
year for which you made the excess contribution. Earnings on the amount
withdrawn must also be withdrawn. The earnings must be included in your income
for the tax year for which the contribution was made and may be subject to a 10%
premature withdrawal tax if you have not reached age 592 (unless an exception to
the 10% penalty tax applies).

WHAT HAPPENS IF I DON'T CORRECT THE EXCESS CONTRIBUTION BY THE TAX RETURN DUE
DATE?

     Any excess contribution withdrawn after the tax return due date (including
any extensions) for the year for which the contribution was made will be subject
to the 6% excise tax. There will be an additional 6% excise tax for each year
the excess remains in your account.

     Unless an excess contribution qualifies for the special treatment outlined
above, the excess contribution and any earnings on it withdrawn after tax filing
time will be includable in taxable income and may be subject to a 10% premature
withdrawal penalty.

     You may reduce the excess contributions by making a withdrawal equal to the
excess. Earnings need not be withdrawn. To the extent that no earnings are
withdrawn, the withdrawal will not be subject to income taxes or possible
penalties for premature withdrawals before age 59 1/2. Excess contributions may
also be corrected in a subsequent year to the extent that you contribute less
than your Roth IRA contribution limit for the subsequent year. As the prior
excess contribution is reduced or eliminated, the 6% excise tax will become
correspondingly reduced or eliminated for subsequent tax years.

CONVERSION OF EXISTING REGULAR IRA

CAN I CONVERT AN EXISTING REGULAR IRA INTO A ROTH IRA?

     Yes, starting in 1998 you can convert an existing Regular IRA into a Roth
IRA if you meet the adjusted gross income (AGI) limits described below.
Conversion may be accomplished either by establishing a Roth IRA and then
transferring the amount in your Regular IRA you wish to convert to the new Roth
IRA. Or, if you want to convert an existing Regular IRA with State Street Bank
as custodian to a Roth IRA, you may give us directions to convert.

     You are eligible to convert a Regular IRA to a Roth IRA if, for the year of
the conversion, your AGI is $100,000 or less. The same limit applies to married
and single taxpayers, and the limit is not indexed to cost-of-living increases.
Married taxpayers are eligible to convert a Regular IRA to a Roth IRA only if
they file a joint income tax return; married taxpayers filing separately are not
eligible to convert.

     NOTE:  No contributions other than Roth IRA conversion contributions made
during the same tax year may be deposited in a single Roth IRA conversion
account.

     CAUTION:  You should be extremely cautious in converting an existing
IRA into a Roth IRA early in a year if there is any possibility that your AGI
for the year will exceed $100,000.  Although a bill pending in Congress would
permit you to transfer amounts back to your Regular IRA if your AGI exceeds
$100,000, under the current rules, if you have already converted during a year
and you turn out to have more than $100,000 of AGI, there may be adverse tax
results for you.  Consult your tax advisor or the IRS for the latest
developments.

WHAT ARE THE TAX RESULTS FROM CONVERTING?

     The taxable amount in your Regular IRA you convert to a Roth IRA will be
considered taxable income on your federal income tax return for the year of the
conversion. All amounts in a Regular IRA are taxable except for your prior non-
deductible contributions to the Regular IRA.

     If you make the conversion during 1998, the taxable income is spread over
four years. In other words, you would include one quarter of the taxable amount
on your federal income tax return for 1998, 1999, 2000 and 2001.

SHOULD I CONVERT MY REGULAR IRA TO A ROTH IRA?

     Only you can answer this question, in consultation with your tax or
financial advisors. A number of factors, including the following, may be
relevant. Conversion may be advantageous if you expect to leave the converted
funds on deposit in your Roth IRA for at least five years and to be able to
withdraw the funds under circumstances that will not be taxable (see below). The
benefits of converting will also depend on whether you expect to be in the same
tax bracket when you withdraw from your Roth IRA as you are now. Also,
conversion is based upon an assumption that Congress will not change the tax
rules for withdrawals from Roth IRAs in the future, but his cannot be
guaranteed.

TRANSFERS/ROLLOVERS
<PAGE>
 
CAN I TRANSFER OR ROLL OVER A DISTRIBUTION I RECEIVE FROM MY EMPLOYER'S
RETIREMENT PLAN INTO A ROTH IRA?

          Distributions from qualified employer-sponsored retirement plans or
403(b) arrangements (for employees of tax-exempt employers) are not eligible for
                                                                ---             
rollover  or direct transfer to a Roth IRA.  However, in certain circumstances
it may be possible to make a direct rollover of an eligible distribution to a
Regular IRA and then to convert the Regular IRA to Roth  IRA (see above).
Consult your tax or  financial advisor for further information on this
possibility.

CAN I MAKE A ROLLOVER FROM MY ROTH IRA TO ANOTHER ROTH IRA?

          You may make a rollover from one Roth IRA to another Roth IRA you have
or you establish to receive the rollover.  Such a rollover must be completed
within 60 days after the withdrawal from your first Roth IRA.  After making a
rollover from one Roth IRA to another, you must wait a full year (365 days)
before you can make another such rollover.  (However, you can instruct a Roth
IRA custodian to transfer amounts directly to another Roth IRA custodian; such a
direct transfer does not count as a rollover.)

HOW DO ROLLOVERS AFFECT MY ROTH IRA CONTRIBUTION LIMITS?

          Rollover contributions, if properly made, do not count toward the
maximum contribution.  Also, you may make a rollover from one Roth IRA to
another even during a year when you are not eligible to contribute to a Roth IRA
(for example, because your AGI for that year is too high).

WITHDRAWALS

WHEN CAN I MAKE WITHDRAWALS FROM MY ROTH IRA?

          You may withdraw from your Roth IRA at any time.  If the withdrawal
meets the requirements discussed below, it is tax-free.  This means that you pay
no federal income tax even though the withdrawal includes earnings or gains on
your contributions while they were held in your Roth IRA.

WHEN MUST I START MAKING WITHDRAWALS?

          There are no rules on when you must start making withdrawals from your
Roth IRA or on minimum required withdrawal amounts for any particular year
during your lifetime.  Unlike Regular IRAs, you are not required to start making
withdrawals from a Roth IRA by the April 1 following the year in which you reach
age 70 1/2.

          After your death, there are IRS rules on the timing and amount of
distributions.  In general, the amount in your Roth IRA must be distributed by
the end of the fifth year after your death.  However, distributions to a
designated beneficiary that begin by the end of the year following the year of
your death and that are paid over the life expectancy of the beneficiary satisfy
the rules.  Also, if your surviving spouse is your designated beneficiary, the
spouse may defer the start of distributions until you would have reached age 70
1/2 had you lived.

WHAT ARE THE REQUIREMENTS FOR A TAX-FREE WITHDRAWAL?

          To be tax-free, a withdrawal from your Roth IRA must meet two
requirements.  First, the Roth IRA must have been open for 5 or more years
before the withdrawal.  Second, at least one of the following conditions must be
satisfied:

          .  You are age 59 1/2 or older when you make the withdrawal.

          .  The withdrawal is made by your beneficiary after you die.

          .  You are disabled (as defined in IRS rules) when you make the
             withdrawal.

          .  You are using the withdrawal to cover eligible first time homebuyer
             expenses. These are the costs of purchasing, building or rebuilding
             a principal residence (including customary settlement, financing or
             closing costs). The purchaser may be you, your spouse or a child,
             grandchild, parent or grandparent of you or your spouse. An
             individual is considered a "first-time homebuyer" if the individual
             (or the individual's spouse, if married) did not have an ownership
             interest in a principal residence during the two-year period
             immediately preceding the acquisition in question. The withdrawal
             must be used for eligible expenses within 120 days after the
             withdrawal (if there is an unexpected delay, or cancellation of the
             home acquisition, a withdrawal may be redeposited as a rollover).

             There is a lifetime limit on eligible first-time homebuyer expenses
             of $10,000 per individual.

          For a Roth IRA that you set up with amounts rolled over or converted
from a Regular IRA, the 5 year period begins with the year in which the
conversion or rollover was made.  (Note:  a bill pending in Congress might
affect this rule -- consult your tax advisor or the IRS for the latest
developments.)

          For a Roth IRA that you started with a normal contribution, the 5 year
period starts with the year for which you make the initial normal contribution.

HOW ARE WITHDRAWALS FROM MY ROTH IRA TAXED IF THE TAX-FREE REQUIREMENTS ARE NOT
MET?

          If the qualified withdrawal requirements are not met, a withdrawal
consisting of your own prior contribution amounts to your Roth IRA will not be
considered taxable income in the year you receive it, nor will the 10% penalty
apply.  To the extent that the nonqualified withdrawal consists of dividends or
gains while your contributions were held in your Roth IRA, the withdrawal is
includable in your gross income in the taxable year you receive it, and may be
subject to the 10% withdrawal penalty.  All amounts withdrawn from your Roth IRA
are considered withdrawals of your contributions until you have withdrawn the
entire amount you have contributed.  After that, all amounts withdrawn are
considered taxable withdrawals of dividends and gains.

          Note that, for purposes of determining what portion of any
distribution is includable in income, all of your Roth IRA accounts are
considered as one single account. Amounts withdrawn from any one Roth IRA
account are deemed to be withdrawn from contributions first. Since all your Roth
IRAs are considered to be one account for this purpose, withdrawals from Roth
IRA accounts are not considered to be from earnings or interest until an amount
equal to all contributions made to all of an individual's  Roth IRA accounts
         ---                       ---
is withdrawn. The following example illustrates this:

          A single individual contributes $1,000 a year to his State Street Bank
and Trust Company Roth IRA account and $1,000 a year to the Brand X Roth IRA
account over a period of ten years. At the end of 10 years his account balances
are as follows:
<PAGE>
 
<TABLE>
<CAPTION>
                                        PRINCIPAL     EARNINGS
                                      CONTRIBUTIONS
<S>                                     <C>           <C>
STATE STREET BANK ROTH IRA               $10,000       $10,000
 
BRAND X ROTH IRA                         $10,000       $10,000
                                         -------       -------

TOTAL                                    $20,000       $20,000
</TABLE>

     At the end of 10 years, this person has $40,000 in both Roth IRA accounts,
of which $20,000 represents his contributions (aggregated) and $20,000
represents his earnings (aggregated).  This individual,  who is 40, withdraws
$15,000 from his Brand X Roth IRA (not a qualified withdrawal).   We look to the
aggregate amount of all principal contributions  in this case $20,000  to
determine if the withdrawal is from contributions, and thus non-taxable.  In
this example, there is no ($0) taxable income as a result of this withdrawal
because the $15,000 withdrawal is less than the total amount of aggregated
contributions ($20,000).  If this individual then withdrew $15,000 from his
State Street Bank Roth IRA, $5,000 would not be taxable (the remaining aggregate
contributions) and $10,000 would be treated as taxable income for the year of
the withdrawal, subject to regular income taxes and the 10% premature withdrawal
penalty (unless an exception applies).

     NOTE:  If passed, a bill currently pending in Congress will change the
rules and the results discussed above.  Under the proposed legislation, in
general, separate Roth IRAs established for annual contributions and conversions
for separate years are not aggregated as explained above to determine the tax on
withdrawals.  See your tax advisor for more information and the latest
developments.

     Taxable withdrawals of dividends and gains from a Roth IRA are treated as
ordinary income.  Withdrawals of taxable amounts from a Roth IRA are not
eligible for averaging treatment currently available to certain lump sum
distributions from qualified employer-sponsored retirement plans, nor are such
withdrawals eligible for taxable gains tax treatment.

     Your receipt of any taxable withdrawal from your Roth IRA before you attain
age 592 generally will be considered as an early withdrawal and subject to a 10%
penalty tax.

     The 10% penalty tax for early withdrawal will not apply if any of the
following exceptions applies:

     -    The withdrawal was a result of your death or disability.

     -    The withdrawal is one of a scheduled series of substantially equal
     periodic payments for your life or life expectancy (or the joint lives or
     life expectancies of you and your beneficiary).

               If there is an adjustment to the scheduled series of payments,
     the 10% penalty tax will apply. For example, if you begin receiving
     payments at age 50 under a withdrawal program providing for substantially
     equal payments over your life expectancy, and at age 58 you elect to
     withdraw the remaining amount in your Roth IRA in a lump-sum, the 10%
     penalty tax will apply to the lump sum and to the amounts previously paid
     to you before age 592 to the extent they were includable in your taxable
     income.

     -    The withdrawal is used to pay eligible higher education expenses.
     These are expenses for tuition, fees, books, and supplies required to
     attend an institution for post-secondary education. Room and board expenses
     are also eligible for a student attending at least half-time. The student
     may be you, your spouse, or your child or grandchild. However, expenses
     that are paid for with a scholarship or other educational assistance
     payment are not eligible expenses.

     -    The withdrawal is used to cover eligible first time homebuyer expenses
     (as described above in the discussion of tax-free withdrawals).

     -    The withdrawal does not exceed the amount of your deductible medical
     expenses for the year (generally speaking, medical expenses paid during a
     year are deductible if they are greater than 72% of your adjusted gross
     income for that year).

     -    The withdrawal does not exceed the amount you paid for health
     insurance coverage for yourself, your spouse and dependents. This exception
     applies only if you have been unemployed and received federal or state
     unemployment compensation payments for at least 12 weeks; this exception
     applies to distributions during the year in which you received the
     unemployment compensation and during the following year, but not to any
     distributions received after you have been reemployed for at least 60 days.

WHAT ABOUT THE 15 PERCENT PENALTY TAX?

     The rule imposing a 15% penalty tax on very large withdrawals from tax-
favored arrangements (including IRAs, 403(b) arrangements and qualified
employer-sponsored plans), or on excess amounts remaining in such tax-favored
arrangements at your death,  has been repealed.  This 15% tax no longer applies.
                                      --------

Statement is based upon the best available information.  However, Roth IRAs are
new under the tax laws, and the IRS has not issued regulations or rulings on the
operation and tax treatment of Roth IRA accounts.  Also, if enacted, legislation
now pending in Congress will change some of the rules.  Therefore, you should
consult your tax advisor for the latest developments or for advice about how
maintaining a Roth IRA will affect your personal tax or financial situation.

applicable to ALL State Street Bank and Trust Company IRAs.

<PAGE>
 
               PART THREE: RULES FOR ALL IRAS (REGULAR AND ROTH)

GENERAL INFORMATION

IRA REQUIREMENTS

          All IRAs must meet certain requirements.  Contributions generally must
be made in cash.  The IRA trustee or custodian must be a bank or other person
who has been approved by the Secretary of the Treasury.  Your contributions may
not be invested in life insurance or collectibles or be commingled with other
property except in a common trust or investment fund.  Your interest in the
account must be nonforfeitable at all times.  You may obtain further information
on IRAs from any district office of the Internal Revenue Service.

MAY I REVOKE MY IRA?

          You may revoke a newly established Regular or Roth IRA at any time
within seven days after the date on which you receive this Disclosure Statement.
A Regular or Roth IRA established more than seven days after the date of your
receipt of this Disclosure Statement may not be revoked.

          To revoke your Regular or Roth IRA, mail or deliver a written notice
of revocation to the Custodian at the address which appears at the end of this
Disclosure Statement.  Mailed notice will be deemed given on the date that it is
postmarked (or, if sent by certified or registered mail, on the date of
certification or registration).  If you revoke your Regular or Roth IRA within
the seven-day period, you are entitled to a return of the entire amount you
originally contributed into your Regular or Roth IRA, without adjustment for
such items as sales charges, administrative expenses or fluctuations in market
value.

INVESTMENTS

HOW ARE MY IRA CONTRIBUTIONS INVESTED?

          You control the investment and reinvestment of contributions to your
Regular or Roth IRA.  Investments must be in one or more of the Fund(s)
available from time to time as listed in the Adoption Agreement for your Regular
or Roth IRA or in an investment selection form provided with your Adoption
Agreement or from the Fund Distributor or Service Company.  You direct the
investment of your IRA by giving your investment instructions to the Distributor
or Service Company for the Fund(s).  Since you control the investment of your
Regular or Roth IRA, you are responsible for any losses; neither the Custodian,
the Distributor nor the Service Company has any responsibility for any loss or
diminution in value occasioned by your exercise of investment control.
Transactions for your Regular or Roth IRA will generally be at the applicable
public offering price or net asset value for shares of the Fund(s) involved next
established after the Distributor or the Service Company (whichever may apply)
receives proper investment instructions from you; consult the current prospectus
for the Fund(s) involved for additional information.

          Before making any investment, read carefully the current prospectus
for any Fund you are considering as an investment for your Regular IRA or Roth
IRA.  The prospectus will contain information about the Fund's investment
objectives and policies, as well as any minimum initial investment or minimum
balance requirements and any sales, redemption or other charges.

          Because you control the selection of investments for your Regular or
Roth IRA and because mutual fund shares fluctuate in value, the growth in value
of your Regular or Roth IRA cannot be guaranteed or projected.

ARE THERE ANY RESTRICTIONS ON THE USE OF MY IRA ASSETS?

          The tax-exempt status of your Regular or Roth IRA will be revoked if
you engage in any of the prohibited transactions listed in Section 4975 of the
tax code.  Upon such revocation, your Regular or Roth IRA is treated as
distributing its assets to you.  The taxable portion of the amount in your IRA
will be subject to income tax (unless, in the case of a Roth IRA, the
requirements for a tax-free withdrawal are satisfied).  Also, you may  be
subject to a 10% penalty tax on the taxable amount as a premature withdrawal if
you have not yet reached the age of 592.

          Any investment in a collectible (for example, rare stamps) by your
Regular or Roth IRA is treated as a withdrawal; the only exception involves
certain types of government-sponsored coins or certain types of precious metal
bullion.

WHAT IS A PROHIBITED TRANSACTION?

          Generally, a prohibited transaction is any improper use of the assets
in your Regular or Roth IRA.  Some examples of prohibited transactions are:

          -  Direct or indirect sale or exchange of property between you
          and your Regular or Roth IRA.

          -  Transfer of any property from your Regular or Roth IRA to
          yourself or from yourself to your Regular or Roth IRA.

          Your Regular or Roth IRA could lose its tax exempt status if you use
all or part of your interest in your Regular or Roth IRA as security for a loan
or borrow any money from your Regular or Roth IRA.  Any portion of your Regular
or Roth IRA used as security for a loan will be treated as a distribution in the
year in which the money is borrowed.  This amount may be taxable and you may
also be subject to the 10%  premature withdrawal penalty on the taxable amount.

FEES AND EXPENSES

CUSTODIAN'S FEES

          The following is a list of the fees charged by the Custodian for
maintaining either a Regular IRA or a Roth IRA.

          Account Installation Fee                          $10.00

          Annual Maintenance Fee per mutual fund            $10.00

          Termination, Rollover, or Transfer of
          Account to Successor Custodian                    $10.00

GENERAL FEE POLICIES

 .    Fees may be paid by you directly, or the Custodian may deduct them from
     your Regular or Roth IRA.

 .    Fees may be changed upon 30 days written notice to you.
<PAGE>
 
 .      The full annual maintenance fee will be charged for any calendar year
during which you have a Regular or Roth IRA with us. This fee is not prorated
for periods of less than one full year.

 .      If provided for in this Disclosure Statement or the Adoption Agreement,
termination fees are charged when your account is closed whether the funds are
distributed to you or transferred to a successor custodian or trustee.

 .      The Custodian may charge you for its reasonable expenses for services not
covered by its fee schedule.

OTHER CHARGES

 .      There may be sales or other charges associated with the purchase or
redemption of shares of a Fund in which your Regular IRA or Roth IRA is
invested.  Before investing, be sure to read carefully the current prospectus of
any Fund you are considering as an investment for your Regular IRA or Roth IRA
for a description of applicable charges.

TAX MATTERS

WHAT IRA REPORTS DOES THE CUSTODIAN ISSUE?

          The Custodian will report all withdrawals to the IRS and the recipient
on the appropriate form. For reporting purposes, a direct transfer of assets to
a successor custodian or trustee is not considered a withdrawal.

          The Custodian will report to the IRS the year-end value of your
account and the amount of any rollover (including conversions of a Regular IRA
to a Roth IRA) or regular contribution made during a calendar year, as well as
the tax year for which a contribution is made. Unless the Custodian receives an
indication from you to the contrary, it will treat any amount as a contribution
for the tax year in which it is received. It is most important that a
                                                --------------       
contribution between January and April 15th for the prior year be clearly
designated as such.

WHAT TAX INFORMATION MUST I REPORT TO THE IRS?

          You must file Form 5329 with the IRS for each taxable year for which
you made an excess contribution or you take a premature withdrawal that is
subject to the 10% penalty tax, or you withdraw less than the minimum amount
required from your Regular IRA. If your beneficiary fails to make required
minimum withdrawals from your Regular or Roth IRA after your death, your
beneficiary may be subject to an excise tax and be required to file Form 5329.

          For Regular IRAs, you must also report each nondeductible contribution
to the IRS by designating it a nondeductible contribution on your tax return.
Use Form 8606. In addition, for any year in which you make a nondeductible
contribution or take a withdrawal, you must include additional information on
your tax return. The information required includes: (1) the amount of your
nondeductible contributions for that year; (2) the amount of withdrawals from
Regular IRAs in that year; (3) the amount by which your total nondeductible
contributions for all the years exceed the total amount of your distributions
previously excluded from gross income; and (4) the total value of all your
Regular IRAs as of the end of the year. If you fail to report any of this
information, the IRS will assume that all your contributions were deductible.
This will result in the taxation of the portion of your withdrawals that should
be treated as a nontaxable return of your nondeductible contributions.

WHICH WITHDRAWALS ARE SUBJECT TO WITHHOLDING?

ROTH IRA

          Federal income tax will be withheld at a flat rate of 10% of any
taxable withdrawal from your Roth IRA, unless you elect not to have tax
withheld. Withdrawals from a Roth IRA are not subject to the mandatory 20%
income tax withholding that applies to most distributions from qualified plans
or 403(b) accounts that are not directly rolled over to another plan or IRA.

REGULAR IRA

          Federal income tax will be withheld at a flat rate of 10% from any
withdrawal from your Regular IRA, unless you elect not to have tax withheld.
Withdrawals from a Regular IRA are not subject to the mandatory 20% income tax
withholding that applies to most distributions from qualified plans or 403(b)
accounts that are not directly rolled over to another plan or IRA.

ACCOUNT TERMINATION

          You may terminate your Regular IRA or Roth IRA at any time after its
establishment by sending a completed withdrawal form (or other withdrawal
instructions in a form acceptable to the Custodian), or a transfer authorization
form, to:

                      STATE STREET BANK AND TRUST COMPANY
                                 P.O. Box  ___
                             BOSTON, MA   ________

          Your Regular IRA or Roth IRA with State Street Bank will terminate
upon the first to occur of the following:

          -    The date your properly executed withdrawal form or instructions
          (as described above) withdrawing your total Regular IRA or Roth IRA
          balance is received and accepted by the Custodian or, if later, the
          termination date specified in the withdrawal form.

          -    The date the Regular IRA or Roth IRA ceases to qualify under the
          tax code.  This will be deemed a termination.

          -    The transfer of the Regular IRA or Roth IRA to another
          custodian/trustee.

          -    The rollover of the amounts in the Regular IRA or Roth IRA to
          another custodian/trustee.

          Any outstanding fees must be received prior to such a termination of
your account.

          The amount you receive from your IRA upon termination of the account
will be treated as a withdrawal, and thus the rules relating to Regular IRA or
Roth IRA withdrawals will apply. For example, if the IRA is terminated before
you reach age 592, the 10% early withdrawal penalty may apply to the taxable
amount you receive.

IRA DOCUMENTS

REGULAR IRA

          The terms contained in Articles I to VII of Part One of the State
Street Bank and Trust Company Universal Individual Retirement Custodial Account
document have been promulgated by the IRS in Form 5305-A for use in establishing
a Regular IRA Custodial Account that meets the requirements of Code Section
<PAGE>
 
408(a) for a valid Regular IRA. This IRS approval relates only to the form of
Articles I to VII and is not an approval of the merits of the Regular IRA or of
any investment permitted by the Regular IRA.

ROTH IRA

     The terms contained in Articles I to VII of Part Two of the State Street
Bank and Trust Company Universal Individual Retirement Account Custodial
Agreement have been promulgated by the IRS in Form 5305-RA for use in
establishing a Roth IRA Custodial Account that meets the requirements of Code
Section 408A for a valid Roth IRA.  This IRS approval relates only to the form
of Articles I to VII and is not an approval of the merits of the Roth IRA or of
any investment permitted by the Roth IRA.

     Based on our legal advice relating to current tax laws and IRS meetings,
State Street Bank believes that the use of a Universal Individual Retirement
Account Information Kit such as this, containing information and documents for
both a Regular IRA or a Roth IRA, will be acceptable to the IRS.  However, if
the IRS makes a ruling, or if Congress enacts legislation, regarding the use of
different documentation, State Street Bank will forward to you new documentation
for your Regular IRA or a Roth IRA (as appropriate) for you to read and, if
necessary, an appropriate new Adoption Agreement to sign. By adopting a Regular
IRA or a Roth IRA using these materials, you acknowledge this possibility and
agree to this procedure if necessary. In all cases, to the extent permitted
State Street Bank will treat your IRA as being opened on the date your account
was opened using the Adoption Agreement in this Kit.

                              -------------------

PART ONE:  PROVISIONS APPLICABLE TO REGULAR IRAs PROVISIONS
- -----------------------------------------------------------

  The following provisions of Articles I to VII are in the form promulgated by
the Internal Revenue Service in Form 5305-A for use in establishing an
individual retirement custodial account.

Article I.

  The Custodian may accept additional cash contributions on behalf of the
Depositor for a tax year of the Depositor.  The total cash contributions are
limited to $2,000 for the tax year unless the contribution is a rollover
contribution described in section 402(c)(but only after December 31, 1992),
403(a)(4), 403(b)(8), 408(d)(3), or an employer contribution to a simplified
employee pension plan as described in section 408(k).  Rollover contributions
before January 1, 1993 include rollovers described in section 402(a)(5),
402(a)(6), 402(a)(7), 403(a)(4), 403(b)(8) or 408(d)(3) of the Code or an
employer contribution to a simplified employee pension plan as described in
section 408(k).

ARTICLE II.

 The Depositor's interest in the balance in the custodial account is
nonforfeitable.

ARTICLE III.

  1.  No part of the custodial funds may be invested in life insurance
contracts, nor may the assets of the custodial account be commingled with other
property except in a common trust fund or common investment fund (within the
meaning of section 408(a)(5) of the Code).

  2.  No part of the custodial funds may be invested in collectibles (within the
meaning of section 408(m) except as otherwise permitted by section 408(m)(3)
which provides an exception for certain gold and silver coins and coins issued
under the laws of any state.

ARTICLE IV.

  1.  Notwithstanding any provisions of this agreement to the contrary, the
distribution of the Depositor's interest in the custodial account shall be made
in accordance with the following requirements and shall otherwise comply with
section 408(a)(6) and Proposed Regulations section 1.408-8, including the
incidental death benefit provisions of Proposed Regulations section 1.401(a)(9)-
2, the provisions of which are incorporated by reference.

  2.  Unless otherwise elected by the time distributions are required to begin
to the Depositor under paragraph 3, or to the surviving spouse under paragraph
4, other than in the case of a life annuity, life expectancies shall be
recalculated annually.  Such election shall be irrevocable as to the Depositor
and the surviving spouse and shall apply to all subsequent years.  The life
expectancy of a nonspouse beneficiary may not be recalculated.

  3.  The Depositor's entire interest in the custodial account must be, or begin
to be, distributed by the Depositor's required beginning date, the April 1
following the calendar year end in which the Depositor reaches age 702.  By that
date, the Depositor may elect, in a manner acceptable to the Custodian, to have
the balance in the custodial account distributed in:

      (a)  A  single-sum payment.

      (b)  An annuity contract that provides equal or substantially equal
                monthly, quarterly, or annual payments over the life of the
                Depositor.

      (c)  An annuity contract that provides equal or substantially equal
                monthly, quarterly, or annual payments over the joint and last
                survivor lives of the Depositor and his or her designated
                beneficiary.

      (d)  Equal or substantially equal annual payments over a specified period
                that may not be longer than the Depositor's life expectancy.

      (e)  Equal or substantially equal annual payments over a specified period
                that may not be longer than the joint life and last survivor
                expectancy of the Depositor and his or her designated
                beneficiary.

  4.  If the Depositor dies before his or her entire interest is distributed to
him or her, the entire remaining interest will be distributed as follows:

      (a)  If the Depositor dies on or after distribution of his or her interest
                has begun, distribution must continue to be made in
                accordance with paragraph 3.

      (b)  If the Depositor dies before distribution of his or her interest has
                begun, the entire remaining interest will, at the election of
                the Depositor or, if the Depositor has not so elected, at the
                election of the beneficiary or beneficiaries, either

           (i)  Be distributed by the December 31 of the year containing the
                  fifth anniversary of the Depositor's death, or

           (ii) Be distributed in equal or substantially equal payments over
                  the life or life expectancy of the designated beneficiary or
                  beneficiaries starting by December 31 of the year following
                  the year of the Depositor's death. If, however, the
                  beneficiary is the Depositor's surviving spouse, then this
                  distribution is not required to begin before December 31 of
                  the year in which the Depositor would have turned age 702.

      (c)  Except where distribution in the form of an annuity meeting the
             requirements of section 408(b)(3) and its related regulations has
             irrevocably commenced, distributions are treated as having begun on
             the Depositor's required beginning date, even though payments may
             actually have been made before that date.
<PAGE>
 
     (d) If the Depositor dies before his or her entire interest has been
           distributed and if the beneficiary is other than the surviving
           spouse, no additional cash contributions or rollover contributions
           may be accepted in the account.

  5.  In the case of distribution over life expectancy in equal or substantially
equal annual payments, to determine the minimum annual payment for each year,
divide the Depositor's entire interest in the custodial account as of the close
of business on December 31 of the preceding year by the life expectancy of the
Depositor (or the joint life and last survivor expectancy of the Depositor and
the Depositor's designated beneficiary, or the life expectancy of the designated
beneficiary, whichever applies.) In the case of distributions under paragraph 3,
determine the initial life expectancy (or joint life and last survivor
expectancy) using the attained ages of the Depositor and designated beneficiary
as of their birthdays in the year the Depositor reaches age 702. In the case of
a distribution in accordance with paragraph 4(b)(ii), determine life expectancy
using the attained age of the designated beneficiary as of the beneficiary's
birthday in the year distributions are required to commence.

  6.  The owner of two or more individual retirement accounts may use the
"alternative method" described in Notice 88-38, 1988-1 C.B. 524, to satisfy the
minimum distribution requirements described above.  This method permits an
individual to satisfy these requirements by taking from one individual
retirement account the amount required to satisfy the requirement for another.

ARTICLE V.

  1.  The Depositor agrees to provide the Custodian with information necessary
for the Custodian to prepare any reports required under section 408(i) and
Regulations sections 1.408-5 and 1.408-6.

  2.  The Custodian agrees to submit reports to the Internal Revenue Service and
the Depositor as prescribed by the Internal Revenue Service.

ARTICLE VI.

  Notwithstanding any other articles which may be added or incorporated, the
provisions of Articles I through III and this sentence will be controlling.  Any
additional articles that are not consistent with section 408(a) and the related
regulations will be invalid.

ARTICLE VII.

  This agreement will be amended from time to time to comply with the provisions
of the Code and related regulations.  Other amendments may be made with the
consent of the persons whose signatures appear on the Adoption Agreement.

                 PART TWO: PROVISIONS APPLICABLE TO ROTH IRAS
                 --------------------------------------------

  The following provisions of Articles I to VII are in the form promulgated by
the Internal Revenue Service in Form 5305-RA for use in establishing a Roth
Individual Retirement Custodial Account.

ARTICLE I

     1.  If this Roth IRA is not designated as a Roth Conversion IRA, then,
except in the case of a rollover contribution described in section 408A(e), the
Custodian will accept only cash contributions and only up to a maximum amount of
$2,000 for any tax year of the Depositor.

     2.  If this Roth IRA is designated as a Roth Conversion IRA, no
contributions other than IRA Conversion Contributions made during the same tax
year will be accepted.

ARTICLE IA

     The $2,000 limit described in Article I is gradually reduced to $0 between
certain levels of adjusted gross income (AGI).  For a single Depositor, the
$2,000 annual contribution is phased out between AGI of $95,000 and $110,000;
for a married Depositor who files jointly, between AGI of $150,000 and $160,000;
and for a married Depositor who files separately, between $0 and $10,000. In
case of a conversion, the Custodian will not accept IRA Conversion Contributions
in a tax year if the Depositor's AGI for that tax year exceeds $100,000 or if
the Depositor is married and files a separate return.  Adjusted gross income is
defined in section 408A(c)(3) and does not include IRA Conversion Contributions.

ARTICLE II

     The Depositor's interest in the balance in the custodial account is
nonforfeitable.

ARTICLE III

     1.  No part of the custodial funds may be invested in life insurance
contracts, nor may the assets of the custodial account be commingled with other
property except in a common trust fund or common investment fund (within the
meaning of section 408(a)(5)).

     2.  No part of the custodial funds may be invested in collectibles (within
the meaning of section 408(m)) except as otherwise permitted by section
408(m)(3), which provides an exception for certain gold, silver, and platinum
coins, coins issued under the laws of any state, and certain bullion.

ARTICLE IV

     1.  If the Depositor dies before his or her entire interest is distributed
to him or her and the Depositor's surviving spouse is not the sole beneficiary,
the entire remaining interest will, at the election of the Depositor or, if the
Depositor has not so elected, at the election of the beneficiary or
beneficiaries, either:

     (a) Be distributed by December 31 of the year containing the fifth
         anniversary of the Depositor's death, or

     (b) Be distributed over the life expectancy of the designated beneficiary
         starting no later than December 31 of the year following the year of
         the Depositor's death.

     If distributions do not begin by the date described in (b), distribution
method (a) will apply.

     2.  In the case of distribution method 1(b) above, to determine the minimum
annual payment for each year, divide the Depositor's entire interest in the
trust as of the close of business on December 31 of the preceding year by the
life expectancy of the designated beneficiary using the attained age of the
designated beneficiary as of the beneficiary's birthday in the year
distributions are required to commence and subtract 1 for each subsequent year.

     3.  If the Depositor's spouse is the sole beneficiary on the Depositor's
date of death, such spouse will then be treated as the Depositor.

ARTICLE V

     1.  The Depositor agrees to provide the Custodian with information
necessary for the Custodian to prepare any reports required under sections
408(i) and 408A(d)(3)(E), and Regulations section 1.408-5 and 1.408-6, and under
guidance published by the Internal Revenue Service.

     2.  The Custodian agrees to submit reports to the Internal Revenue Service
and the Depositor as prescribed by the Internal Revenue Service.

ARTICLE VI

     Notwithstanding any other articles which may be added or incorporated, the
provisions of Articles I through IV and this sentence will be controlling.  Any
additional articles that are not consistent with section 408A, the related
regulations, and other published guidance will be invalid.

ARTICLE VII

     This agreement will be amended from time to time to comply with the
provisions of the Code, related regulations, and other published guidance. Other
amendments may be made with the consent of the persons whose signatures appear
below.
<PAGE>
 
PART THREE:  PROVISIONS APPLICABLE TO BOTH REGULAR IRAS AND ROTH IRAS
- ---------------------------------------------------------------------

ARTICLE VIII.

  1. As used in this Article VIII the following terms have the following
meanings:

  "Account" or "Custodial Account" means the individual retirement account
established using the terms of either Part One or Part Two and, in either event,
Part Three of this State Street Bank and Trust Company Universal Individual
Retirement Account Custodial Agreement and the Adoption Agreement signed by the
Depositor.  The Account may be a Regular Individual Retirement Account or a Roth
Individual Retirement Account, as specified by the Depositor.  See Section 24
below.

  "Custodian" means State Street Bank and Trust Company.

  "Fund" means any registered investment company which is advised, sponsored or
distributed by Sponsor; provided, however, that such a mutual fund or registered
investment company must be legally offered for sale in the state of the
Depositor's residence.

  "Distributor" means the entity which has a contract with the Fund(s) to serve
as distributor of the shares of such Fund(s).

  In any case where there is no Distributor, the duties assigned hereunder to
the Distributor may be performed by the Fund(s) or by an entity that has a
contract to perform management or investment advisory services for the Fund(s).

  "Service Company" means any entity employed by the Custodian or the
Distributor, including the transfer agent for the Fund(s), to perform various
administrative duties of either the Custodian or the Distributor.

  In any case where there is no Service Company, the duties assigned hereunder
to the Service Company will be performed by the Distributor (if any) or by an
entity specified in the second preceding paragraph.

  "Sponsor" means [insert fund management company or other fund entity that is
making Fund(s) available under this Agreement and has the power to appoint a
successor Custodian.]

  2. The Depositor may revoke the Custodial Account established hereunder by
mailing or delivering a written notice of revocation to the Custodian within
seven days after the Depositor receives the Disclosure Statement related to the
Custodial Account.  Mailed notice is treated as given to the Custodian on date
of the postmark (or on the date of Post Office certification or registration in
the case of notice sent by certified or registered mail).  Upon timely
revocation, the Depositor's initial contribution will be returned, without
adjustment for administrative expenses, commissions or sales charges,
fluctuations in market value or other changes.

  The Depositor may certify in the Adoption Agreement that the Depositor
received the Disclosure Statement related to the Custodial Account at least
seven days before the Depositor signed the Adoption Agreement to establish the
Custodial Account, and the Custodian may rely upon such certification.

  3. All contributions to the Custodial Account shall be invested and reinvested
in full and fractional shares of one or more Funds. Such investments shall be
made in such proportions and/or in such amounts as Depositor from time to time
in the Adoption Agreement or by other written notice to the Service Company (in
such form as may be acceptable to the Service Company) may direct.

  The Service Company shall be responsible for promptly transmitting all
investment directions by the Depositor for the purchase or sale of shares of one
or more Funds hereunder to the Funds' transfer agent for execution.  However, if
investment directions with respect to the investment of any contribution
hereunder are not received from the Depositor as required or, if received, are
unclear or incomplete in the opinion of the Service Company, the contribution
will be returned to the Depositor, or will be held uninvested (or invested in a
money market fund if available) pending clarification or completion by the
Depositor, in either case without liability for interest or for loss of income
or appreciation.  If any other directions or other orders by the Depositor with
respect to the sale or purchase of shares of one or more Funds for the Custodial
Account are unclear or incomplete in the opinion of the Service Company, the
Service Company will refrain from carrying out such investment directions or
from executing any such sale or purchase, without liability for loss of income
or for appreciation or depreciation of any asset, pending receipt of
clarification or completion from the Depositor.

  All investment directions by Depositor will be subject to any minimum initial
or additional investment or minimum balance rules applicable to a Fund as
described in its prospectus.

  All dividends and capital gains or other distributions received on the shares
of any Fund held in the Depositor's Account shall be (unless received in
additional shares) reinvested in full and fractional shares of such Fund (or of
any other Fund offered by the Sponsor, if so directed).

  4. Subject to the minimum initial or additional investment, minimum balance
and other exchange rules applicable to a Fund, the Depositor may at any time
direct the Service Company to exchange all or a specified portion of the shares
of a Fund in the Depositor's Account for shares and fractional shares of one or
more other Funds.  The Depositor shall give such directions by written notice
acceptable to the Service Company, and the Service Company will process such
directions as soon as practicable after receipt thereof (subject to the second
paragraph of Section 3 of this Article VIII).

  5. Any purchase or redemption of shares of a Fund for or from the Depositor's
Account will be effected at the public offering price or net asset value of such
Fund (as described in the then effective prospectus for such Fund) next
established after the Service Company has transmitted the Depositor's investment
directions to the transfer agent for the Fund(s).

  Any purchase, exchange, transfer or redemption of shares of a Fund for or from
the Depositor's Account will be subject to any applicable sales, redemption or
other charge as described in the then effective prospectus for such Fund.

  6. The Service Company shall maintain adequate records of all purchases or
sales of shares of one or more Funds for the Depositor's Custodial Account.  Any
account maintained in connection herewith shall be in the name of the Custodian
for the benefit of the Depositor.  All assets of the Custodial Account shall be
registered in the name of the Custodian or of a suitable nominee.  The books and
records of the Custodian shall show that all such investments are part of the
Custodial Account.
<PAGE>
 
  The Custodian shall maintain or cause to be maintained adequate records
reflecting transactions of the Custodial Account.  In the discretion of the
Custodian, records maintained by the Service Company with respect to the Account
hereunder will be deemed to satisfy the Custodian's recordkeeping
responsibilities therefor.  The Service Company agrees to furnish the Custodian
with any information the Custodian requires to carry out the Custodian's
recordkeeping responsibilities.

  7.  Neither the Custodian nor any other party providing services to the
Custodial Account will have any responsibility for rendering advice with respect
to the investment and reinvestment of Depositor's Custodial Account, nor shall
such parties be liable for any loss or diminution in value which results from
Depositor's exercise of investment control over his Custodial Account.
Depositor shall have and exercise exclusive responsibility for and control over
the investment of the assets of his Custodial Account, and neither Custodian nor
any other such party shall have any duty to question his directions in that
regard or to advise him regarding the purchase, retention or sale of shares of
one or more Funds for the Custodial Account.

  8.  The Depositor may in writing appoint an investment advisor with respect to
the Custodial Account on a form acceptable to the Custodian and the Service
Company.  The investment advisor's appointment will be in effect until written
notice to the contrary is received by the Custodian and the Service Company.
While an investment advisor's appointment is in effect, the investment advisor
may issue investment directions or may issue orders for the sale or purchase of
shares of one or more Funds to the Service Company, and the Service Company will
be fully protected in carrying out such investment directions or orders to the
same extent as if they had been given by the Depositor.

  The Depositor's appointment of any investment advisor will also be deemed to
be instructions to the Custodian and the Service Company to pay such investment
advisor's fees to the investment advisor from the Custodial Account hereunder
without additional authorization by the Depositor or the Custodian.

  9.  Distribution of the assets of the Custodial Account shall be made at such
time and in such form as Depositor (or the Beneficiary if Depositor is deceased)
shall elect by written order to the Custodian.  Depositor acknowledges that any
distribution of a taxable amount from the Custodial Account (except for
distribution on account of Depositor's disability or death, return of an "excess
contribution" referred to in Code Section 4973, or a "rollover" from this
Custodial Account) made earlier than age 592 may subject Depositor to an
"additional tax on early distributions" under Code Section 72(t) unless an
exception to such additional tax is applicable.  For that purpose, Depositor
will be considered disabled if Depositor can prove, as provided in Code Section
72(m)(7), that Depositor is unable to engage in any substantial gainful activity
by reason of any medically determinable physical or mental impairment which can
be expected to result in death or be of long-continued and indefinite duration.
It is the responsibility of the Depositor (or the Beneficiary) by appropriate
distribution instructions to the Custodian to insure that any applicable
distribution requirements of Code Section 401(a)(9) and Article IV above are
met.  If the Depositor (or Beneficiary) does not direct the Custodian to make
distributions from the Custodial Account by the time that such distributions are
required to commence in accordance with such distribution requirements, the
Custodian (and Service Company) shall assume that the Depositor (or Beneficiary)
is meeting the minimum distribution requirements from another individual
retirement arrangement maintained by the Depositor (or Beneficiary) and the
Custodian and Service Company shall be fully protected in so doing.  The
Depositor (or the Depositor's surviving spouse) may elect to comply with the
distribution requirements in Article IV using the recalculation of life
expectancy method, or may elect that the life expectancy of the Depositor and/or
the Depositor's surviving spouse, as applicable, will not be recalculated; any
such election may be in such form as the Depositor (or surviving spouse)
provides (including the calculation of minimum distribution amounts in
accordance with a method that does not provide for recalculation of the life
expectancy of one or both of the Depositor and surviving spouse and instructions
for withdrawals to the Custodian in accordance with such method).
Notwithstanding paragraph 2 of Article IV, unless an election to have life
expectancies recalculated annually is made by the time distributions are
required to begin, life expectancies shall not be recalculated.  Neither the
Custodian nor any other party providing services to the Custodial Account
assumes any responsibility for the tax treatment of any distribution from the
Custodial Account; such responsibility rests solely with the person ordering the
distribution.

  10. The Custodian assumes (and shall have) no responsibility to make any
distribution except upon the written order of Depositor (or Beneficiary if
Depositor is deceased) containing such information as the Custodian may
reasonably request.  Also, before making any distribution or honoring any
assignment of the Custodial Account, Custodian shall be furnished with any and
all applications, certificates, tax waivers, signature guarantees and other
documents (including proof of any legal representative's authority) deemed
necessary or advisable by Custodian, but Custodian shall not be responsible for
complying with any order or instruction which appears on its face to be genuine,
or for refusing to comply if not satisfied it is genuine, and Custodian has no
duty of further inquiry.  Any distributions from the Account may be mailed,
first-class postage prepaid, to the last known address of the person who is to
receive such distribution, as shown on the Custodian's records, and such
distribution shall to the extent thereof completely discharge the Custodian's
liability for such payment.

  11. (a)  The term "Beneficiary" means the person or persons designated as such
             by the "designating person" (as defined below) on a form acceptable
             to the Custodian for use in connection with the Custodial Account,
             signed by the designating person, and filed with the Custodian. The
             form may name individuals, trusts, estates, or other entities as
             either primary or contingent beneficiaries. However, if the
             designation does not effectively dispose of the entire Custodial
             Account as of the time distribution is to commence, the term
             "Beneficiary" shall then mean the designating person's estate with
             respect to the assets of the Custodial Account not disposed of by
             the designation form. The form last accepted by the Custodian
             before such distribution is to commence, provided it was received
             by the Custodian (or deposited in the U.S. Mail or with a reputable
             delivery service) during the designating person's lifetime, shall
             be controlling and, whether or not fully dispositive of the
             Custodial Account, thereupon shall revoke all such forms previously
             filed by that person. The term "designating person" means Depositor
             during his/her lifetime; after Depositor's death, it also means
             Depositor's spouse, but only if the spouse elects to treat the
             Custodial Account as the spouse's own Custodial Account in
             accordance with applicable provisions of the Code.

      (b)  When and after distributions from the Custodial Account to
             Depositor's Beneficiary commence, all rights and obligations
             assigned to Depositor hereunder shall inure to, and be enjoyed and
             exercised by, Beneficiary instead of Depositor.

  12. (a)  The Depositor agrees to provide information to the Custodian at such
             time and in such manner as may be necessary for the Custodian to
             prepare any reports
<PAGE>
 
           required under Section 408(i) or Section 408A(d)(3)(E) of the Code
           and the regulations thereunder or otherwise.

    (b) The Custodian or the Service Company will submit reports to the Internal
          Revenue Service and the Depositor at such time and manner and
          containing such information as is prescribed by the Internal Revenue
          Service.

    (c) The Depositor, Custodian and Service Company shall furnish to each other
          such information relevant to the Custodial Account as may be required
          under the Code and any regulations issued or forms adopted by the
          Treasury Department thereunder or as may otherwise be necessary for
          the administration of the Custodial Account.

    (d) The Depositor shall file any reports to the Internal Revenue Service
          which are required of him by law (including Form 5329), and neither
          the Custodian nor Service Company shall have any duty to advise
          Depositor concerning or monitor Depositor's compliance with such
          requirement.

13. (a) Depositor retains the right to amend this Custodial Account document in
          any respect at any time, effective on a stated date which shall be at
          least 60 days after giving written notice of the amendment (including
          its exact terms) to Custodian by registered or certified mail, unless
          Custodian waives notice as to such amendment. If the Custodian does
          not wish to continue serving as such under this Custodial Account
          document as so amended, it may resign in accordance with Section 17
          below.

    (b) Depositor delegates to the Custodian the Depositor's right so to amend,
          provided (i) the Custodian does not change the investments available
          under this Custodial Agreement and (ii) the Custodian amends in the
          same manner all agreements comparable to this one, having the same
          Custodian, permitting comparable investments, and under which such
          power has been delegated to it; this includes the power to amend
          retroactively if necessary or appropriate in the opinion of the
          Custodian in order to conform this Custodial Account to pertinent
          provisions of the Code and other laws or successor provisions of law,
          or to obtain a governmental ruling that such requirements are met, to
          adopt a prototype or master form of agreement in substitution for this
          Agreement, or as otherwise may be advisable in the opinion of the
          Custodian. Such an amendment by the Custodian shall be communicated in
          writing to Depositor, and Depositor shall be deemed to have consented
          thereto unless, within 30 days after such communication to Depositor
          is mailed, Depositor either (i) gives Custodian a written order for a
          complete distribution or transfer of the Custodial Account, or (ii)
          removes the Custodian and appoints a successor under Section 17 below.

          Pending the adoption of any amendment necessary or desirable to
          conform this Custodial Account document to the requirements of any
          amendment to any applicable provision of the Internal Revenue Code or
          regulations or rulings thereunder, the Custodian and the Service
          Company may operate the Depositor's Custodial Account in accordance
          with such requirements to the extent that the Custodian and/or the
          Service Company deem necessary to preserve the tax benefits of the
          Account.

    (c) Notwithstanding the provisions of subsections (a) and (b) above, no
          amendment shall increase the responsibilities or duties of Custodian
          without its prior written consent.

    (d) This Section 13 shall not be construed to restrict the Custodian's right
          to substitute fee schedules in the manner provided by Section 16
          below, and no such substitution shall be deemed to be an amendment of
          this Agreement.

14. (a) Custodian shall terminate the Custodial Account if this Agreement is
          terminated or if, within 30 days (or such longer time as Custodian may
          agree) after resignation or removal of Custodian under Section 17,
          Depositor or Sponsor, as the case may be, has not appointed a
          successor which has accepted such appointment. Termination of the
          Custodial Account shall be effected by distributing all assets thereof
          in a single payment in cash or in kind to Depositor, subject to
          Custodian's right to reserve funds as provided in Section 17.

    (b) Upon termination of the Custodial Account, this custodial account
          document shall have no further force and effect (except for Sections
          15(f), 17(b) and (c) hereof which shall survive the termination of the
          Custodial Account and this document), and Custodian shall be relieved
          from all further liability hereunder or with respect to the Custodial
          Account and all assets thereof so distributed.

15. (a) In its discretion, the Custodian may appoint one or more contractors or
          service providers to carry out any of its functions and may compensate
          them from the Custodial Account for expenses attendant to those
          functions. In the event of such appointment, all rights and privileges
          of the Custodian under this Agreement shall pass through to such
          contractors or service providers who shall be entitled to enforce them
          as if a named party.

    (b) The Service Company shall be responsible for receiving all instructions,
          notices, forms and remittances from Depositor and for dealing with or
          forwarding the same to the transfer agent for the Fund(s).

    (c) The parties do not intend to confer any fiduciary duties on Custodian or
          Service Company (or any other party providing services to the
          Custodial Account), and none shall be implied. Neither shall be liable
          (or assumes any responsibility) for the collection of contributions,
          the proper amount, time or tax treatment of any contribution to the
          Custodial Account or the propriety of any contributions under this
          Agreement, or the purpose, time, amount (including any minimum
          distribution amounts), tax treatment or propriety of any distribution
          hereunder, which matters are the sole responsibility of Depositor and
          Depositor's Beneficiary.

    (d) Not later than 60 days after the close of each calendar year (or after
          the Custodian's resignation or removal), the Custodian or Service
          Company shall file with Depositor a written report or reports
          reflecting the transactions effected by it during such period and the
          assets of the Custodial Account at its close. Upon the expiration of
          60 days after such a report is sent to Depositor (or Beneficiary), the
          Custodian or Service
<PAGE>
 
          Company shall be forever released and discharged from all liability
          and accountability to anyone with respect to transactions shown in or
          reflected by such report except with respect to any such acts or
          transactions as to which Depositor shall have filed written objections
          with the Custodian or Service Company within such 60 day period.

    (e) The Service Company shall deliver, or cause to be delivered, to
          Depositor all notices, prospectuses, financial statements and other
          reports to shareholders, proxies and proxy soliciting materials
          relating to the shares of the Funds(s) credited to the Custodial
          Account. No shares shall be voted, and no other action shall be taken
          pursuant to such documents, except upon receipt of adequate written
          instructions from Depositor.

    (f) Depositor shall always fully indemnify Service Company, Distributor, the
          Fund(s), Sponsor and Custodian and save them harmless from any and all
          liability whatsoever which may arise either (i) in connection with
          this Agreement and the matters which it contemplates, except that
          which arises directly out of the Service Company's, Distributor's,
          Fund's, Sponsor's or Custodian's bad faith, gross negligence or
          willful misconduct, (ii) with respect to making or failing to make any
          distribution, other than for failure to make distribution in
          accordance with an order therefor which is in full compliance with
          Section 10, or (iii) actions taken or omitted in good faith by such
          parties. Neither Service Company nor Custodian shall be obligated or
          expected to commence or defend any legal action or proceeding in
          connection with this Agreement or such matters unless agreed upon by
          that party and Depositor, and unless fully indemnified for so doing to
          that party's satisfaction.

    (g) The Custodian and Service Company shall each be responsible solely for
          performance of those duties expressly assigned to it in this
          Agreement, and neither assumes any responsibility as to duties
          assigned to anyone else hereunder or by operation of law.

    (h) The Custodian and Service Company may each conclusively rely upon and
          shall be protected in acting upon any written order from Depositor or
          Beneficiary, or any investment advisor appointed under Section 8, or
          any other notice, request, consent, certificate or other instrument or
          paper believed by it to be genuine and to have been properly executed,
          and so long as it acts in good faith, in taking or omitting to take
          any other action in reliance thereon. In addition, Custodian will
          carry out the requirements of any apparently valid court order
          relating to the Custodial Account and will incur no liability or
          responsibility for so doing.

16. (a) The Custodian, in consideration of its services under this Agreement,
          shall receive the fees specified on the applicable fee schedule. The
          fee schedule originally applicable shall be the one specified in the
          Adoption Agreement or Disclosure Statement, as applicable. The
          Custodian may substitute a different fee schedule at any time upon 30
          days' written notice to Depositor. The Custodian shall also receive
          reasonable fees for any services not contemplated by any applicable
          fee schedule and either deemed by it to be necessary or desirable or
          requested by Depositor.

    (b) Any income, gift, estate and inheritance taxes and other taxes of any
          kind whatsoever, including transfer taxes incurred in connection with
          the investment or reinvestment of the assets of the Custodial Account,
          that may be levied or assessed in respect to such assets, and all
          other administrative expenses incurred by the Custodian in the
          performance of its duties (including fees for legal services rendered
          to it in connection with the Custodial Account) shall be charged to
          the Custodial Account. If the Custodian is required to pay any such
          amount, the Depositor (or Beneficiary) shall promptly upon notice
          thereof reimburse the Custodian.

    (c) All such fees and taxes and other administrative expenses charged to the
          Custodial Account shall be collected either from the amount of any
          contribution or distribution to or from the Account, or (at the option
          of the person entitled to collect such amounts) to the extent possible
          under the circumstances by the conversion into cash of sufficient
          shares of one or more Funds held in the Custodial Account (without
          liability for any loss incurred thereby). Notwithstanding the
          foregoing, the Custodian or Service Company may make demand upon the
          Depositor for payment of the amount of such fees, taxes and other
          administrative expenses. Fees which remain outstanding after 60 days
          may be subject to a collection charge.

17. (a) Upon 30 days' prior written notice to the Custodian, Depositor or
          Sponsor, as the case may be, may remove it from its office hereunder.
          Such notice, to be effective, shall designate a successor custodian
          and shall be accompanied by the successor's written acceptance. The
          Custodian also may at any time resign upon 30 days' prior written
          notice to Sponsor, whereupon the Sponsor shall notify the Depositor
          (or Beneficiary) and shall appoint a successor to the Custodian. In
          connection with its resignation hereunder, the Custodian may, but is
          not required to, designate a successor custodian by written notice to
          the Sponsor or Depositor (or Beneficiary), and the Sponsor or
          Depositor (or Beneficiary) will be deemed to have consented to such
          successor unless the Sponsor or Depositor (or Beneficiary) designates
          a different successor custodian and provides written notice thereof
          together with such a different successor's written acceptance by such
          date as the Custodian specifies in its original notice to the Sponsor
          or Depositor (or Beneficiary) (provided that the Sponsor or Depositor
          (or Beneficiary) will have a minimum of 30 days to designate a
          different successor).

    (b) The successor custodian shall be a bank, insured credit union, or other
          person satisfactory to the Secretary of the Treasury under Code
          Section 408(a)(2). Upon receipt by Custodian of written acceptance by
          its successor of such successor's appointment, Custodian shall
          transfer and pay over to such successor the assets of the Custodial
          Account and all records (or copies thereof) of Custodian pertaining
          thereto, provided that the successor custodian agrees not to dispose
          of any such records without the Custodian's consent. Custodian is
          authorized, however, to reserve such sum of money or property as it
          may deem advisable for payment of all its fees, compensation, costs,
          and expenses, or for payment of any other liabilities constituting a
          charge on or against the assets of the Custodial Account or on or
          against the Custodian, with
<PAGE>
 
          any balance of such reserve remaining after the payment of all such
          items to be paid over to the successor custodian.

    (c) Any Custodian shall not be liable for the acts or omissions of its
          predecessor or its successor.

  18.  References herein to the "Internal Revenue Code" or "Code" and sections
thereof shall mean the same as amended from time to time, including successors
to such sections.

  19.  Except where otherwise specifically required in this Agreement, any
notice from Custodian to any person provided for in this Agreement shall be
effective if sent by first-class mail to such person at that person's last
address on the Custodian's records.

  20.  Depositor or Depositor's Beneficiary shall not have the right or power to
anticipate any part of the Custodial Account or to sell, assign, transfer,
pledge or hypothecate any part thereof.  The Custodial Account shall not be
liable for the debts of Depositor or Depositor's Beneficiary or subject to any
seizure, attachment, execution or other legal process in respect thereof except
to the extent required by law.  At no time shall it be possible for any part of
the assets of the Custodial Account to be used for or diverted to purposes other
than for the exclusive benefit of the Depositor or his/her Beneficiary except to
the extent required by law.

  21.  When accepted by the Custodian, this Agreement is accepted in and shall
be construed and administered in accordance with the laws of the state where the
principal offices of the Custodian are located.  Any action involving the
Custodian brought by any other party must be brought in a state or federal court
in such state.

       If in the Adoption Agreement, Depositor designates that the Custodial
Account is a Regular IRA, this Agreement is intended to qualify under Code
Section 408(a) as an individual retirement Custodial Account and to entitle
Depositor to the retirement savings deduction under Code Section 219 if
available. If in the Adoption Agreement Depositor designates that the Custodial
Account is a Roth IRA, this Agreement is intended to qualify under Code Section
408A as a Roth individual retirement Custodial Account and to entitle Depositor
to the tax-free withdrawal of amounts from the Custodial Account to the extent
permitted in such Code section.

       If any provision hereof is subject to more than one interpretation or any
term used herein is subject to more than one construction, such ambiguity shall
be resolved in favor of that interpretation or construction which is consistent
with the intent expressed in whichever of the two preceding sentences is
applicable.

       However, the Custodian shall not be responsible for whether or not such
intentions are achieved through use of this Agreement, and Depositor is referred
to Depositor's attorney for any such assurances.

  22.  Depositor should seek advice from Depositor's attorney regarding the
legal consequences (including but not limited to federal and state tax matters)
of entering into this Agreement, contributing to the Custodial Account, and
ordering Custodian to make distributions from the Account. Depositor
acknowledges that Custodian and Service Company (and any company associated
therewith) are prohibited by law from rendering such advice.

  23.  If any provision of any document governing the Custodial Account provides
for notice, instructions or other communications from one party to another in
writing, to the extent provided for in the procedures of the Custodian, Service
Company or another party, any such notice, instructions or other communications
may be given by telephonic, computer, other electronic or other means, and the
requirement for written notice will be deemed satisfied.

  24.  The legal documents governing the Custodial Account are as follows:

(a)    If in the Adoption Agreement the Depositor designated the Custodial
       Account as a Regular IRA under Code Section 408(a), the provisions of
       Part One and Part Three of this Agreement and the provisions of the
       Adoption Agreement are the legal documents governing the Depositor's
       Custodial Account.

(b)    If in the Adoption Agreement the Depositor designated the Custodial
       Account as a Roth IRA under Code Section 408A, the provisions of Part Two
       and Part Three of this Agreement and the provisions of the Adoption
       Agreement are the legal documents governing the Depositor's Custodial
       Account.

(c)    In the Adoption Agreement the Depositor must designate the Custodian
       Account as either a Roth IRA or a Regular IRA, and a separate account
       will be established for such IRA. One Custodial Account may not serve as
       a Roth IRA and a Regular IRA (through the use of subaccounts or
       otherwise).

  25.  Articles I through VII of Part One of this Agreement are in the form
promulgated by the Internal Revenue Service as Form 5305-A.  It is anticipated
that, if and when the Internal Revenue Service promulgates changes to Form 5305-
A, the Custodian will amend this Agreement correspondingly.


  Articles I through VII of Part Two of this Agreement are in the form
promulgated by the Internal Revenue Service as Form 5305-RA. It is anticipated
that, if and when the Internal Revenue Service promulgates changes to Form 5305-
RA, the Custodian will amend this Agreement correspondingly.

       The Internal Revenue Service has endorsed the use of documentation
permitting a Depositor to establish either a Regular IRA or Roth IRA (but not
both using a single Adoption Agreement), and this Kit complies with the
requirements of the IRS guidance for such use. If the Internal Revenue Service
subsequently determines that such an approach is not permissible, or that the
use of a "combined" Adoption Agreement does not establish a valid Regular IRA or
a Roth IRA (as the case may be), the Custodian will furnish the Depositor with
replacement documents and the Depositor will if necessary sign such replacement
documents. Depositor acknowledge and agrees to such procedures and to cooperate
with Custodian to preserve the intended tax treatment of the Account.

  26.  If the Depositor maintains an Individual Retirement Account under Code
section 408(a), Depositor may convert or transfer such other IRA to a Roth IRA
under Code section 408A using the terms of this Agreement and the Adoption
Agreement by completing and executing the Adoption Agreement and giving suitable
directions to the Custodian and the custodian or trustee of such other IRA.
Alternatively, the Depositor may convert or transfer such other IRA to a Roth
IRA by use of a reply card or by telephonic, computer or electronic means in
accordance with procedures adopted by the Custodian or Service Company intended
to meet the requirements of Code section 408A, and the Depositor will be deemed
to have executed the Adoption Agreement and adopted the provisions of this
Agreement and the Adoption Agreement in accordance with such procedures.

  27.  The Depositor acknowledges that he or she has received and read the
current prospectus for each Fund in which his or her Account is invested and the
Individual Retirement Account Disclosure Statement related to the Account.  The
Depositor represents under penalties of perjury that his or her Social Security
number (or other Taxpayer Identification Number) as stated in the Adoption
Agreement is correct.
