Class A, B and C Shares of:

CHANGE OF INVESTMENT OBJECTIVE AND POLICIES FOR MICRO-CAP EQUITY FUND

The Board of Directors of The Munder Funds, Inc. has changed the investment
objective of the Munder Micro-Cap Equity Fund from long term capital
appreciation to capital appreciation and approved certain changes to the
Fund's investment policies, as set forth below. The description of the Munder
Micro-Cap Equity Fund in the prospectus is hereby deleted in its entirety and
replaced with the following:

GOAL AND PRINCIPAL INVESTMENTS. The Fund's goal is to provide capital
appreciation. It invests primarily in Equity Securities of small
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
within the market capitalization range of companies included in the
Wilshire Micro-Cap Index. As of the date of this Supplement, such
capitalizations do not exceed approximately $300 million, 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

. may benefit from changes in technology, regulations and industry sector
trends

.are still in the developmental stage and may have limited product lines.

There is no limit on the length of operating history for the companies in
which the Fund may invest. The Fund may invest without limit in initial public
offerings of small capitalization companies.

PORTFOLIO MANAGEMENT. A committee of professional portfolio managers
employed by the Advisor makes investment decisions for the Fund.

CHANGE OF INVESTMENT POLICY FOR SMALL-CAP VALUE FUND

The Board of Directors of The Munder Funds, Inc. has changed the investment
policy of the Munder Small-Cap Value Fund to increase the market
capitalization of the issuers considered to be small-cap companies.
Accordingly, the second paragraph of the description of the Munder Small-Cap
Value Fund in the prospectus is hereby deleted and replaced with the
following:

. Under normal market conditions, the Fund will invest at least 65% of its
assets in Equity Securities of companies with market capitalizations
within the market capitalization range of companies included in the
Russell 2000 Index. As of the date of this Supplement, such
capitalizations do not exceed approximately $1.5 billion, which is less
than the market capitalization of S&P 500 companies.

WHAT ARE THE RISKS OF INVESTING IN THE FUNDS ?

The Boards of Directors/Trustees of The Munder Funds have approved the
following addition to the above-referenced provision of the prospectus:

The Funds may from time to time engage in short-term trading in Equity
Securities, including initial public offerings. Such short-term trading may
result in increased transaction costs and expenses and the realization of
short-term capital gains and losses.
<PAGE>

RESTRICTIONS ON EXCESSIVE PURCHASE AND EXCHANGE TRANSACTIONS

The Funds have determined to institute the following amendment to their
policies concerning purchase and exchange transactions in order to limit
excessive trading in shares of the Funds:

The exchange privilege is not intended as a vehicle for short-term trading.
Excessive exchange activity may interfere with portfolio management and have
an adverse effect on all shareholders. Each Fund and its distributor reserve
the right to refuse any purchase or exchange request that could adversely
affect the fund or its operations, including those from any individual or
group who, in the Fund's view, is likely to engage in excessive trading or any
order considered market-timing activity. If a Fund refuses a purchase or
exchange request and the shareholder deems it necessary to redeem their
account, any CDSC as permitted by the prospectus will be applicable.

Additionally, in no event will any Fund permit more than six exchanges into
or out of a Fund in any one-year period per account, tax identification
number, social security number or related investment group. The Munder Money
Market Funds are exempt from this policy. Please see "How Can I Exchange
Shares?" in the prospectus for additional information concerning exchanges.

FUND HIGHLIGHTS

The "FUND HIGHLIGHTS--What Are the Key Facts Regarding the Funds? --What

hereby deleted in its entirety and replaced with the following:

Q: What are the options for investment in the Funds?

A:Each Fund, other than the NetNet Fund, offers five different investment
options, or classes: Class A, B, C, K and Y. The NetNet Fund offers four
different investment options, or classes: Class A, B, C and Y. Class K and Y
shares, which are only offered to institutional and other qualified investors,

</TABLE>

*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. 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.
