          SPECIAL MEETING OF SHAREHOLDERS TO BE HELD DECEMBER 11, 2002

Dear Shareholder:

     Please take note that a SPECIAL MEETING OF SHAREHOLDERS OF THE MUNDER MONEY
MARKET FUND, a series of The Munder Funds, Inc. ("Company"), will be held on
December 11, 2002, at the offices of Munder Capital Management, 480 Pierce
Street, Birmingham, Michigan 48009, at 10:00 a.m., Eastern time ("Meeting").

     The Board of Directors ("Board") of the Company has proposed that the
Munder Money Market Fund ("Money Market Fund") be reorganized with and into the
Munder Cash Investment Fund ("Cash Investment Fund"), a separate series of The
Munder Funds Trust ("Trust"), to seek future economies of scale and to eliminate
certain costs of running the Funds separately. If shareholders of the Money
Market Fund approve the Agreement and Plan of Reorganization ("Reorganization
Agreement") described in the accompanying materials, all of the assets of the
Money Market Fund will be exchanged for an equivalent dollar amount of shares of
the Cash Investment Fund on or about December 13, 2002 ("Reorganization"). The
shares of the Cash Investment Fund will then be transferred to the shareholders
of the Money Market Fund in complete liquidation of the Money Market Fund. The
proposed transaction is intended to be a tax-free reorganization. As a result,
it is anticipated that shareholders will not recognize any gain or loss in
connection with the proposed Reorganization. WE STRONGLY INVITE YOUR
PARTICIPATION BY ASKING YOU TO REVIEW THESE MATERIALS AND COMPLETE AND RETURN
YOUR PROXY CARD AS SOON AS POSSIBLE.

     The Board believes that shareholders of the Money Market Fund will benefit
from the proposed Reorganization. The proposed Reorganization will enable
shareholders of the Money Market Fund to experience higher asset levels in the
combined Cash Investment Fund, which will result in the fixed and relatively
fixed costs associated with operating the Money Market Fund being spread over a
larger asset base, thereby reducing per share expenses paid by Money Market Fund
shareholders. While current


shareholders of the Cash Investment Fund will likely not realize these same
benefits immediately following the proposed Reorganization, they will hopefully
benefit in a similar manner at some point in the future as the addition of the
assets from the Money Market Fund moves the Cash Investment Fund closer to
achieving certain economies of scale.

     THE BOARD STRONGLY URGES YOU TO VOTE FOR APPROVAL OF THE PROPOSED
REORGANIZATION AGREEMENT.

     As a result of the Reorganization, the Money Market Fund would be combined
with the Cash Investment Fund and you would become a shareholder of the Cash
Investment Fund, receiving shares of the Cash Investment Fund having an
aggregate net asset value equal to the aggregate net asset value of your
investment in the Money Market Fund. No sales charges will be imposed as a
result of the Reorganization. The closing of the Reorganization will be
conditioned upon, among other things, receiving an opinion of counsel to the
effect that the proposed Reorganization will qualify as a tax-free
reorganization for Federal income tax purposes.

     The Cash Investment Fund, like the Money Market Fund, seeks a high level of
current interest income consistent with maintaining liquidity and stability of
principal. Both the Money Market Fund and the Cash Investment Fund have engaged
Munder Capital Management as both their investment adviser and their
administrator. Both the Money Market Fund and the Cash Investment Fund also have
a common distributor (Funds Distributor, Inc.).

     Detailed information about the proposed Reorganization and the reasons for
it are contained in the enclosed materials. Please exercise your right to vote
by completing, dating and signing the enclosed proxy card. A self-addressed,
postage-paid envelope has been enclosed for your convenience. IT IS VERY
IMPORTANT THAT YOU VOTE AND THAT YOUR VOTING INSTRUCTIONS BE RECEIVED NO LATER
THAN DECEMBER 10, 2002.


     NOTE: You may receive more than one proxy package if you hold shares in
more than one account. You must return separate proxy cards for separate
holdings. We have provided postage-paid return envelopes for each, which require
no postage if mailed in the United States.

     If you have any questions after considering the enclosed materials, please
call 1-800-239-3334.
                                       Sincerely,

                                       [JAMES C. ROBINSON SIG]

                PROXY STATEMENT/PROSPECTUS DATED OCTOBER 7, 2002

                             THE MUNDER FUNDS, INC.

                               480 PIERCE STREET
                           BIRMINGHAM, MICHIGAN 48009
                                 (800) 239-3334

                       SPECIAL MEETING OF SHAREHOLDERS OF
                            MUNDER MONEY MARKET FUND
                          TO BE HELD DECEMBER 11, 2002

     This combined Proxy Statement and Prospectus ("Proxy Statement/
Prospectus") is being furnished in connection with the solicitation of proxies
by the Board of Directors ("Board") of the Munder Money Market Fund ("Money
Market Fund"), a series of The Munder Funds, Inc. ("Company"), for a Special
Meeting of Shareholders of the Money Market Fund ("Meeting"). The Meeting will
be held on December 11, 2002, at 10:00 a.m., Eastern time, at the offices of
Munder Capital Management, 480 Pierce Street, Birmingham, Michigan 48009.

     At the Meeting, shareholders of the Money Market Fund will be asked to
consider and act upon the following proposals:

     (1) To approve or disapprove an Agreement and Plan of Reorganization
         providing for the acquisition of all of the assets of the Money Market
         Fund by the Munder Cash Investment Fund ("Cash Investment Fund"), a
         series of The Munder Funds Trust ("Trust"), and the assumption of all
         liabilities of the Money Market Fund by the Cash Investment Fund in
         exchange for shares of the Cash Investment Fund and the subsequent
         liquidation of the Money Market Fund; and

     (2) To transact such other business as may properly come before the Meeting
         or any adjournments or postponements thereof.

     This Proxy Statement/Prospectus is soliciting shareholders of the Money
Market Fund to approve an Agreement and Plan of Reorganization ("Reorganization
Agreement"). The Reorganization Agreement contemplates the transfer of all of
the assets of the Money Market Fund to the Cash Investment Fund and the
assumption by the Cash Investment Fund of all of the liabilities of the Money
Market Fund in exchange for shares of the Cash Investment Fund having an
aggregate value equal to the net asset value of the Money Market Fund
("Reorganization"). The

                                        5


Money Market Fund would then distribute to its shareholders the portion of the
shares of the Cash Investment Fund to which each such shareholder is entitled.
This would result in a liquidation of the Money Market Fund.

     Under the proposed Reorganization Agreement, each shareholder of the Money
Market Fund would be entitled to receive shares of the Cash Investment Fund
having an aggregate value equal to the aggregate value of the shares of the
Money Market Fund held by that shareholder, as of the close of business on the
business day of the closing of the Reorganization. You are being asked to
approve the Reorganization Agreement pursuant to which the Reorganization
transaction would be accomplished. Because shareholders of the Money Market Fund
are being asked to approve a transaction that will result in their holding
shares of the Cash Investment Fund, this Proxy Statement also serves as a
Prospectus for the Cash Investment Fund.

     If the Reorganization Agreement is approved by shareholders of the Money
Market Fund, holders of Class A, Class B, Class C and Class Y shares of the
Money Market Fund will receive Class A, Class B, Class C and Class Y shares,
respectively, of the Cash Investment Fund. Subsequent to the Reorganization, any
contingent deferred sales charge ("CDSC") that applied to a shareholder's Class
B or Class C shares of the Money Market Fund at the time of Reorganization will
continue to apply for the holding period applicable at the time of the
Reorganization. In calculating any applicable CDSC, the period during which a
shareholder held the Class B or Class C shares of the Money Market Fund will be
included in the holding period.

     This transaction is being structured as a tax-free reorganization. See
"Information About the Reorganization -- Federal Income Tax Consequences."
Shareholders should consult their tax advisors to determine the actual impact of
the Reorganization in light of their individual tax circumstances.

     The Money Market Fund is a diversified series of the Company. The Money
Market 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 Money
Market Fund pursues its goal by investing in a broad range of U.S.
dollar-denominated money market instruments. The Money Market Fund invests
solely in U.S. dollar-denominated debt securities with remaining maturities of
13 months or less and maintains an average dollar-weighted portfolio maturity of
90 days or less.

                          COMMON QUESTIONS AND ANSWERS
                       ABOUT THE PROPOSED REORGANIZATION

Q.  HOW WILL THE REORGANIZATION AFFECT ME?

A.  The assets of the Money Market Fund will be combined with those of the Cash
    Investment Fund and you will become a shareholder of the Cash Investment
    Fund. Following the Reorganization, you will receive shares of the Cash
    Investment Fund that are equal in value to the shares of the Money Market
    Fund that you held immediately prior to the closing of the Reorganization.
    (Shareholders of Class A shares, Class B shares, Class C shares and Class Y
    shares of the Money Market Fund will receive Class A shares, Class B shares,
    Class C shares and Class Y shares, respectively, of the Cash Investment
    Fund.)

Q.  WHY IS THE REORGANIZATION BEING RECOMMENDED?

A.  The primary purposes of the proposed Reorganization are to seek future
    economies of scale and to eliminate certain costs associated with operating
    the Money Market Fund and the Cash Investment Fund separately. We believe
    the Reorganization will benefit shareholders of the Money Market Fund
    without adversely impacting shareholders of the Cash Investment Fund.

    Shareholders of the Money Market Fund, especially the Class B and Class C
    shareholders, have recently experienced disappointingly low yields. Although
    the low yields can primarily be attributed to the temporarily declining
    interest-rate environment, we believe the Cash Investment Fund is in a
    better position to weather adverse changes in market conditions now and in
    the future. In addition, the Money Market Fund is a relatively small fund
    with a high number of small accounts and a slow growth rate. All of these
    factors drive up the Fund's expense ratio. Without a significant increase in
    assets, yields will continue to suffer. If yields remain low, investors will
    seek other higher yielding alternatives and expense ratios will likely rise,
    causing yields to drop even further. Accordingly, we feel merging the Money
    Market Fund into the Cash Investment Fund would be in the best interests of
    the Money Market Fund's shareholders.

    The Money Market Fund and the Cash Investment Fund have identical investment
    objectives and policies, as described in detail below. The Reorganization
    will result in combining the assets of these two Funds and consolidating
    their operations.
                                        11


     Combining the assets of the Funds is intended to provide various benefits
     to shareholders of the Money Market Fund who become shareholders of the
     Cash Investment Fund (as well as to existing and future investors of the
     Cash Investment Fund). For example, the proposed Reorganization will enable
     shareholders of the Money Market Fund to experience higher asset levels in
     the combined Cash Investment Fund, which will result in the fixed and
     relatively fixed costs associated with operating the Money Market Fund,
     such as transfer agency, accounting and printing expenses, being spread
     over a larger asset base, thereby reducing per share expenses paid by Money
     Market Fund shareholders. It is not anticipated that current shareholders
     of the Cash Investment Fund will realize these same benefits as a result of
     the proposed Reorganization but will hopefully benefit in a similar manner
     at some point in the future as the addition of the assets from the Money
     Market Fund moves the Cash Investment Fund closer to achieving certain
     economies of scale. (See also the next question regarding operating
     expenses of the Funds.) Higher asset levels also should benefit portfolio
     management by permitting larger individual portfolio investments that may
     result in reduced transaction costs and/or more favorable pricing.

Q.   HOW DO THE FEES PAID BY THE CASH INVESTMENT FUND COMPARE TO THOSE PAYABLE
     BY THE MONEY MARKET FUND?

A.   Both the management fees and the total per share operating expenses of the
     Cash Investment Fund are lower than those of the Money Market Fund. Pro
     forma fee and expense information is included for your reference in this
     Proxy Statement/Prospectus.

Q.   WILL I HAVE TO PAY ANY SALES LOAD, COMMISSION OR OTHER TRANSACTIONAL FEE IN
     CONNECTION WITH THE REORGANIZATION?

A.   No. The full value of your shares of the Money Market Fund will be
     exchanged for shares of the indicated class of the Cash Investment Fund
     without any sales load, commission or other transactional fee being
     imposed. MCM will bear all of the expenses of both Funds in connection with
     the Reorganization, except for brokerage fees and brokerage expenses
     associated with the Reorganization.

                                        12


Q.   WHO WILL SERVE AS INVESTMENT ADVISER AND PROVIDE OTHER SERVICES TO THE CASH
     INVESTMENT FUND?

A.   The Cash Investment Fund has the same investment adviser (MCM), the same
     administrator (also MCM) and the same distributor (Funds Distributor, Inc.)
     as the Money Market Fund.

Q.   WILL I HAVE TO PAY ANY FEDERAL INCOME TAXES AS A RESULT OF THE
     REORGANIZATION?

A.   The transaction is intended to qualify as a tax-free reorganization for
     Federal income tax purposes. Accordingly, shareholders will not recognize
     taxable gain or loss as a result of the Reorganization. As a condition to
     the closing of the Reorganization, the Money Market Fund will receive an
     opinion of counsel to the effect that the Reorganization will qualify as a
     tax-free reorganization for Federal income tax purposes. You should
     separately consider any state, local and other tax consequences in
     consultation with your tax advisor. Opinions of counsel are not binding on
     the IRS or the courts.

Q.   WILL I CONTINUE TO BE ABLE TO EXCHANGE MY SHARES FOR SHARES OF OTHER FUNDS
     OF THE MUNDER FAMILY OF MUTUAL FUNDS?

A.   Yes. Holders of Class A, Class B, Class C and Class Y shares of the Money
     Market Fund may, either before or after the Reorganization, exchange their
     shares for shares of the same class of other funds of the Company, the
     Trust and The Munder Framlington Funds Trust ("Munder Funds"), subject to
     certain restrictions described in the prospectus of each fund. Before
     requesting any such exchange, shareholders should carefully review the
     applicable prospectus for the other fund to ensure that the fund meets
     their investment objectives and needs.

                                    SUMMARY

     This summary is qualified in its entirety by reference to the additional
information contained elsewhere in this Proxy Statement/Prospectus and the
Agreement and Plan of Reorganization ("Reorganization Agreement"), a copy of
which is attached to this Proxy Statement/ Prospectus as Exhibit A.

PROPOSED REORGANIZATION

     At a meeting of the Board on August 13, 2002, the Board approved the
Reorganization Agreement. Subject to the approval of the shareholders of the
Money Market Fund, the Reorganization Agreement provides for:

     - the transfer of all of the assets of the Money Market Fund to the Cash
       Investment Fund and the assumption by the Cash Investment Fund of all of
       the liabilities of the Money Market Fund in exchange for shares of the
       Cash Investment Fund having an aggregate value equal to the assets and
       liabilities of the Money Market Fund;

     - the distribution to each of the shareholders of the Money Market Fund of
       shares of the Cash Investment Fund having an aggregate net asset value
       equal to the aggregate net asset value of the shares of the Money Market
       Fund held by that shareholder; and

     - the complete liquidation of the Money Market Fund.

     We expect the Reorganization to be effective upon the close of business on
December 13, 2002, or on a later date as the parties may agree ("Closing Date").
As a result of the Reorganization, each shareholder of the Money Market Fund
will become the owner of the number of full and fractional shares of the Cash
Investment Fund having an aggregate net asset value equal to the aggregate net
asset value of the shareholder's Money Market Fund shares as of the close of
business on the Closing Date. Shareholders of Class A shares, Class B shares,
Class C shares and Class Y shares of the Money Market Fund will receive Class A
shares, Class B shares, Class C shares and Class Y shares, respectively, of the
Cash Investment Fund. See "Information About the Reorganization" below.

     For the reasons set forth below under "Reasons for the Reorganization," the
Board of Directors of the Company, including all of the Directors who are not
"interested persons" (as that term is defined in the Investment Company Act of
1940, as amended ("1940 Act")) of the Company ("Independent Directors"), has
concluded that the Reorganization would be in the best interests of the
shareholders of the

                                        14


Money Market Fund and that the interests of the Money Market Fund's existing
shareholders would not be diluted as a result of the Reorganization, and
therefore has submitted the Reorganization Agreement for approval to you, the
Money Market Fund's shareholders. THE BOARD RECOMMENDS THAT YOU VOTE "FOR" THE
PROPOSED REORGANIZATION AGREEMENT EFFECTING THE REORGANIZATION. The Board of
Trustees for the Trust has also approved the Reorganization on behalf of the
Cash Investment Fund.

     Approval of the Reorganization will require the affirmative vote of the
holders of a majority of the outstanding shares of the Money Market Fund with
all classes voting together and not by class. See "Voting Information."

INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS

     The Money Market Fund and the Cash Investment Fund have identical
investment objectives and policies and have substantially similar investment
restrictions. The goal of both the Money Market Fund and the Cash Investment
Fund is to provide as high a level of current interest income as is consistent
with maintaining liquidity and stability of principal.

     Each Fund pursues its goal by investing in a broad range of U.S.
dollar-denominated money market instruments. Each Fund invests solely in U.S.
dollar-denominated debt securities with remaining maturities of 13 months or
less and maintains an average dollar-weighted portfolio maturity of 90 days or
less.

PERFORMANCE OF THE MONEY MARKET FUND AND THE CASH INVESTMENT FUND

     The bar charts and tables that follow give some indication of the risk of
an investment in the Funds. The bar charts show each Fund's performance for each
calendar year since inception. The table shows the Funds' average annual total
returns for different calendar periods over the life of each Fund. When you
consider this information, please remember the Funds' performance in past years
is not necessarily an indication of how the Funds will perform in the future.

     The annual returns in the bar charts, the best and worst quarter returns
and the average annual total return chart are those of each Fund's Class Y
shares. Please see "Summary Comparison of Fees and Expenses" below for
information about the difference between the share classes. Performance for
Class A, Class B and Class C shares, net of any sales charges (loads) and
shareholder servicing fee/12b-1 fees would have been substantially similar to
that of the Class Y shares of the Funds because the

                                        15


shares are invested in the same portfolio of securities and have the same
portfolio management. However, the performance of the Class A, Class B and Class
C shares would have been lower than that of the Class Y shares because of the
higher fees and expenses of those classes of shares.

SUMMARY COMPARISON OF FEES AND EXPENSES

     The following tables compare the fees and expenses of each class of the
Money Market Fund and the Cash Investment Fund and show the estimated fees and
expenses for each class on a pro forma basis, giving effect to the proposed
Reorganization. We have estimated these pro forma numbers in good faith, based
on information contained in the Annual Reports for the previous fiscal year for
each class of shares for each Fund, with certain adjustments.

                                        17


     The fee and expense information shown on the table below is organized as
follows:

     - Column 1 reflects the actual fees and expenses of each class of the Money
       Market Fund calculated at the Fund's fiscal year end, June 30, 2002.

     - Column 2 reflects the actual fees and expenses of each class of the Cash
       Investment Fund calculated at the Fund's fiscal year end, June 30, 2002.

     - Column 3 reflects the pro forma fees and expenses of the Cash Investment
       Fund as if the Reorganization had occurred on June 30, 2002. These pro
       forma fees and expenses have been adjusted to reflect any expected
       savings that may occur as a result of the Funds being combined in the
       Reorganization.

(a) A contingent deferred sales charge (CDSC) is a one-time fee charged at the
    time of redemption. If you redeem Class A shares of the Money Market Fund
    that were acquired through an exchange from another Munder Fund or Funds
    that you purchased as part of an investment of $1,000,000 or more, and your
    redemption occurs within one year of your original Munder Fund purchase(s),
    a 1% CDSC will apply upon redemption. Any CDSC on Class A shares of the
    Money Market Fund that was applicable on the Reorganization Date will
    continue to apply after the Reorganization and will continue to age from the
    date of the original Munder Fund purchase(s).

(b) Effective October 31, 2002, if you redeem Class A shares of the Cash
    Investment Fund that were acquired after October 31, 2002 through an
    exchange from another Munder Fund or Funds that you purchased as part of an
    investment of $1,000,000 or more, and your redemption occurs within one year
    of your original Munder Fund purchase(s), a 1% CDSC will apply upon
    redemption. For purposes of this CSDC, Class A shares of the Cash Investment
    Fund received in the Reorganization will continue to age from the date of
    the original Munder Fund purchase(s) rather than from the date the Class A
    shares of the Money Market Fund were acquired.

(c) Expenses for Class B shares and Class C shares, which had not commenced
    operations as of the date of this Proxy/Prospectus, are based on historical
    information for Class A shares.

(d) The CDSC payable upon redemption of Class B shares declines over time.

(e) The CDSC applies to redemptions of Class C shares within one year of
    purchase.

EXAMPLE

     This Example is intended to help you compare the cost of investing in each
Fund and the combined Cash Investment Fund with the cost of investing in other
mutual funds.

     The Example assumes that you invest $10,000 in each Fund for the time
periods indicated. The example also assumes that your investment has a 5% return
each year and that each Fund's operating expenses remain the same. Although your
actual costs may be higher or lower, based on these assumptions your costs would
be:

     Following the Reorganization and in the ordinary course of business as a
mutual fund, certain holdings of the Money Market Fund that are transferred to
the Cash Investment Fund in connection with the Reorganization may be sold. Any
sales of the Money Market Fund's holdings may result in additional transaction
costs for the Cash Investment Fund (which will not be assumed or paid by MCM)
and will be a taxable event that will result in the realization of taxable gains
or losses from such sales for the Cash Investment Fund.

                                        22


PURCHASE AND REDEMPTION PROCEDURES

     Purchases and redemptions of shares are subject to certain minimum
investment requirements, charges, and waivers of charges applicable to the
various classes of both the Money Market Fund and the Cash Investment Fund. For
details on how to purchase or redeem shares of either Fund, see "How to
Purchase, Sell and Exchange Shares."

EXCHANGE PRIVILEGES

     You may exchange shares of each class of each Fund for shares of the same
class in other Munder Funds to the extent the class exists and shares are
offered for sale in the shareholder's state of residence and subject to any
applicable sales charge. You may exchange Class C shares of each Fund for Class
C or Class II shares of other Munder Funds, based on their relative net asset
values ("NAVs"). Class B and Class C shares will continue to age from the date
of the original purchase and will retain the same CDSC rate in effect before the
exchange. We will not impose any exchange fee on any of these exchange
privileges. Any exchange will be a taxable event for which you may have to
recognize a gain or loss under Federal income tax law. We reserve the right to
amend or terminate the exchange privilege at any time. See "How to Purchase,
Sell and Exchange Shares -- Exchanging Shares," below.

DIVIDENDS AND DISTRIBUTIONS

     The Money Market Fund and the Cash Investment Fund each declare dividends
from net investment income daily and pay them monthly. Both Funds distribute net
realized capital gains, if any, at least annually. As described in more detail
in "How to Purchase, Sell and Exchange Shares -- Distributions," below,
dividends are generally subject to Federal income tax. For both Funds, all
dividends and distributions are reinvested automatically in additional shares of
the respective Fund at net asset value, without a sales charge or CDSC, unless
the shareholder elects to be paid in cash. Following the Reorganization, Money
Market Fund shareholders that have elected to receive distributions in cash will
continue to receive distributions in such manner from the Cash Investment Fund.
See "How to Purchase, Sell and Exchange Shares -- Distributions" in the Proxy
Statement/Prospectus for more information.

TAX CONSEQUENCES

     Prior to completion of the Reorganization, the Money Market Fund will have
received from counsel an opinion to the effect that the
                                        23


Reorganization will qualify as a tax-free reorganization for Federal income tax
purposes. See "Information about the Reorganization -- Federal Income Tax
Consequences."

SHAREHOLDER VOTING RIGHTS

     Neither the Money Market Fund, a series of a Maryland corporation, nor the
Cash Investment Fund, a series of a Massachusetts business trust, holds annual
shareholder meetings. The 1940 Act requires that a shareholder meeting be called
for the purpose of electing Directors/ Trustees at such time as fewer than a
majority of Directors/Trustees holding office have been elected by shareholders.
Either Fund will hold a shareholder meeting upon the written request of
shareholders holding at least 10% of that Fund's outstanding shares.

APPRAISAL RIGHTS

     Under the laws of the Commonwealth of Massachusetts and the Trust's
Declaration of Trust, shareholders of the Cash Investment Fund do not have
appraisal rights in connection with a combination or acquisition of the assets
of another entity. Under the laws of the State of Maryland and the Company's
Articles of Incorporation, shareholders of the Money Market Fund do not have
appraisal rights in connection with a combination or acquisition of the assets
of the Money Market Fund by another entity.

RISK FACTORS

     Because the Money Market Fund and the Cash Investment Fund invest in
identical types of securities, investment in these Funds involves identical
investment risks. See "Comparison of Investment Objectives and Policies" herein.

     Credit (or Default) Risk. An issuer of a security may default on its
payment obligations. Also, an issuer may suffer adverse changes in its financial
condition that could lower the credit quality of a security, leading to greater
volatility in the price of the security and in shares of a Fund. A change in the
quality rating of a bond can also affect the bond's liquidity and make it more
difficult for the Fund to sell.

     Interest Rate Risk. An increase in prevailing interest rates will cause
fixed income securities held by the Fund to decline in value. When interest
rates fall, the reverse is true. Longer-term bonds are generally more sensitive
to interest rates changes than shorter-term bonds. Generally, the

                                        24


longer the average maturity of the bonds held by each Fund, the more the Fund's
share price will fluctuate in response to interest rate changes.

     Prepayment Risk. The Funds may experience losses when an issuer exercises
its right to pay principal on an obligation held by the Fund (such as an
asset-backed security or mortgage-backed security) earlier than expected. This
may happen during a period of declining interest rates. Under these
circumstances, each Fund may be unable to recoup all of its initial investment
and will suffer from having to reinvest in lower yielding securities. The loss
of higher yielding securities and the reinvestment at lower interest rates can
reduce each Fund's income, total return and share price. Rates of prepayment,
faster or slower than expected, could reduce each Fund's yield, increase the
volatility of the Fund and/or cause a decline in net asset value. Certain types
of mortgage-backed securities, such as collateralized mortgage obligations, may
be more volatile and less liquid than other types.

                         REASONS FOR THE REORGANIZATION

     Currently, the Money Market Fund and the Cash Investment Fund are
investment portfolios of separate open-end management investment companies, and
each Fund must separately bear certain costs of its own operations.
Consolidating their separate operations should generally benefit the
shareholders of both Funds by promoting more efficient operations on a more
cost-effective basis. Also, combining assets of the Funds should create future
economies of scale resulting from the larger asset base of the combined fund
after the Reorganization. However, there can be no assurance that the
combination of the Funds will produce more efficient operations on a
cost-effective basis or that economies of scale will be realized.

     MCM believes that certain investment management efficiencies and other
benefits could be realized through the combination of the Funds. The
Reorganization would permit the shareholders of the Money Market Fund to pursue
their investment goals in a larger fund that has investment objectives, policies
and restrictions that are identical with those of the Money Market Fund. A
larger fund should enhance the ability of MCM to effect portfolio transactions
on more favorable terms and give MCM greater investment flexibility and the
ability to select a larger number of portfolio securities with the attendant
benefits of increased diversification. A larger fund should also not be as
significantly affected in the event of high levels of shareholder redemptions.
In addition, the larger aggregate net assets should enable the combined fund
over the long term to obtain the
                                        25


benefits of economies of scale, permitting the reduction of certain costs and
expenses which may result in lower overall expense ratios through the spreading
of fixed costs of operations over a larger asset base. As a general rule,
economies of scale can be realized with respect to fixed expenses, such as
printing costs and fees for certain professional services, although expenses
that are based on the value of assets or on the number of shareholder accounts,
such as transfer agent fees, would be largely unaffected by the Reorganization.
Moreover, we cannot assure you that economies of scale can be realized.

     In light of the foregoing considerations, the Board of Directors of the
Company unanimously concluded that the Reorganization is in the best interests
of the Money Market Fund and its shareholders and that the Reorganization would
not result in a dilution of the interests of the Money Market Funds
shareholders. Similarly, the Board of Trustees of the Trust also approved the
Reorganization and determined that it is in the best interests of the Cash
Investment Fund and its shareholders to acquire the assets of the Money Market
Fund and that the interests of the Cash Investment Fund's shareholders would not
be diluted as a result of the Reorganization.

                      INFORMATION ABOUT THE REORGANIZATION

REORGANIZATION AGREEMENT

     The following summary of the Reorganization Agreement is qualified in its
entirety by reference to the form of Reorganization Agreement attached to this
Proxy Statement/Prospectus as Exhibit A. The Reorganization Agreement provides
that the Cash Investment Fund will acquire all of the assets, subject to all of
the liabilities, of the Money Market Fund in exchange for shares of the Cash
Investment Fund. Subject to the satisfaction of the conditions described below,
such acquisition is scheduled to occur on the Closing Date, or such later date
as may be agreed upon by the parties. The net asset value per share of the Money
Market Fund and the net asset value per share of the Cash Investment Fund will
be determined by dividing the combined Cash Investment Fund's assets, less
liabilities, by the total number of its outstanding shares.

     Both the Money Market Fund and the Cash Investment Fund will utilize State
Street Bank and Trust Company to determine the value of their respective
portfolio securities. The Money Market Fund and the Cash Investment Fund also
will use the same independent pricing services to determine the value of each
security so that State Street Bank and Trust
                                        26


Company can determine the aggregate value of each Fund's portfolio. The method
of valuation employed will be in accordance with the procedures described in the
current prospectuses, as set forth in the Reorganization Agreement, which is
consistent with Rule 22c-1 under the 1940 Act and with the interpretations of
such rule by the SEC.

     The number of full and fractional shares of the Cash Investment Fund you
will receive in the Reorganization will be equal in value to the value of your
Money Market Fund shares as of the close of regularly scheduled trading on the
New York Stock Exchange ("NYSE") on the Closing Date. As promptly as practicable
after the Closing Date, the Money Market Fund will liquidate and distribute pro
rata to its shareholders of record as of the close of regularly scheduled
trading on the NYSE on the Closing Date the shares of the Cash Investment Fund
received by the Money Market Fund in the Reorganization. We will accomplish the
liquidation and distribution with respect to each class of the Money Market
Fund's shares by the transfer of the Cash Investment Fund shares then credited
to the account of the Money Market Fund on the books of the Cash Investment Fund
to open accounts on the share records of the Cash Investment Fund in the names
of the Money Market Fund shareholders. The aggregate net asset value of Class A,
Class B, Class C and Class Y Cash Investment Fund shares to be credited to Class
A, Class B, Class C and Class Y Money Market Fund shareholders, respectively,
will, with respect to each class, be equal to the aggregate net asset value of
the shares of common stock ($0.01 par value per share) of the Money Market Fund
of the corresponding class owned by Money Market Fund shareholders on the
Closing Date. All issued and outstanding shares of the Money Market Fund will
simultaneously be canceled on the books of the Money Market Fund, although share
certificates representing interests in Class A, Class B, Class C and Class Y
shares of the Money Market Fund will represent a number of Class A, Class B,
Class C and Class Y shares, respectively, of Cash Investment Fund shares after
the Closing Date. The Cash Investment Fund will not issue certificates
representing the Class A, Class B, Class C and Class Y Cash Investment Fund
shares issued in connection with such exchange.

     After such distribution, the Company will take all necessary steps under
Maryland law, the Company's Articles of Incorporation and any other applicable
law to effect a complete dissolution of the Money Market Fund.

     The Board of Directors of the Company has determined, with respect to the
Money Market Fund, and the Board of Trustees of the Trust has

                                        27


determined, with respect to the Cash Investment Fund, that the interests of
shareholders of each of those Funds will not be diluted as a result of the
Reorganization and that participation in the Reorganization is in the best
interests of each of those Funds and its shareholders. MCM will bear the
expenses of the Reorganization, including the cost of a proxy soliciting agent
that has been retained.

     The Reorganization Agreement may be terminated and the Reorganization
abandoned at any time prior to the consummation of the Reorganization, before or
after approval by the shareholders of the Money Market Fund, if circumstances
should develop that, in the Board's opinion, make proceeding with the
Reorganization inadvisable. The Reorganization Agreement provides that the
Company and the Trust may waive compliance with any of the covenants or
conditions made therein for the benefit of either Fund, other than the
requirements that: (i) the Reorganization Agreement be approved by shareholders
of the Money Market Fund; and (ii) the Company receive the opinion of the
Company's counsel that the transaction contemplated by the Reorganization
Agreement will constitute a tax-free reorganization for Federal income tax
purposes.

     Approval of the Reorganization Agreement will require the affirmative vote
of a majority of the shares of the Money Market Fund, with all classes voting
together and not by class. See "Voting Information." If the Reorganization
Agreement is not approved by the shareholders of the Money Market Fund, or is
not consummated for any other reason, the Board will consider other possible
courses of action.

     THE BOARD OF DIRECTORS OF THE COMPANY, INCLUDING ALL OF THE INDEPENDENT
DIRECTORS, HAS UNANIMOUSLY RECOMMENDED APPROVAL OF THE REORGANIZATION AGREEMENT.

     Shareholders of the Money Market Fund as of the Record Date will receive
shares of the Cash Investment Fund in accordance with the procedures provided
for in the Reorganization Agreement, as described above. Each such share will be
fully paid and non-assessable when issued and will have no pre-emptive or
conversion rights, except for Class B shares, as more fully described below in
"How to Purchase, Sell and Exchange Shares."

                                        28


DESCRIPTION OF THE CASH INVESTMENT FUND'S SHARES

     Full and fractional shares of the respective class of shares of beneficial
interest of the Cash Investment Fund will be issued to the Money Market Fund's
shareholders in accordance with the procedures detailed in the Reorganization
Agreement. The Cash Investment Fund no longer issues share certificates. The
shares of the Cash Investment Fund to be issued to Money Market Fund
shareholders and recorded on the shareholder records of the transfer agent will
have no pre-emptive or conversion rights, except for Class B shares, as more
fully described below in "How to Purchase, Sell and Exchange Shares."

FEDERAL INCOME TAX CONSEQUENCES

     The Reorganization is intended to qualify for Federal income tax purposes
as a tax-free reorganization described in Section 368(a) of the Internal Revenue
Code of 1986, as amended ("Code"), with no gain or loss recognized as a
consequence of the Reorganization by the Cash Investment Fund, the Money Market
Fund, or the shareholders of the Money Market Fund. As a condition to the
closing of the Reorganization, the Money Market Fund will receive a legal
opinion to that effect. That opinion will be based upon certain representations
and warranties made by the Money Market Fund and the Cash Investment Fund and
certifications received from each of the Funds and certain of their service
providers.

     Immediately prior to the Reorganization, the Money Market Fund will pay a
dividend or dividends which, together with all previous dividends, will have the
effect of distributing to its shareholders all of the Money Market Fund's
investment company taxable income for taxable years ending on or prior to the
Closing Date (computed without regard to any deduction for dividends paid) and
all of its net capital gain, if any, realized in taxable years ending on or
prior to the Closing Date (after reduction for any available capital loss
carryforward). Such dividends will be included in the taxable income of the
Money Market Fund's shareholders.

     You should consult your tax advisor regarding the effect, if any, of the
proposed Reorganization in light of your individual circumstances. Since the
foregoing discussion only relates to the Federal income tax consequences of the
Reorganization, you should also consult your tax advisor as to state and other
local tax consequences, if any, of the Reorganization.

     The following discussion comparing investment objectives, policies and
restrictions of the Money Market Fund and the Cash Investment Fund is based upon
and qualified in its entirety by the respective investment

objectives, policies and restrictions sections of the prospectuses of the Money
Market Fund and the Cash Investment Fund dated October 31, 2001 with respect to
all classes of shares, as supplemented August 15, 2002 with respect to Class A,
Class B and Class C shares and November 15, 2001, December 21, 2001 and August
15, 2002 with respect to Class Y shares. In addition, on August 16, 2002, a
post-effective amendment to the Prospectus of the Cash Investment Fund was filed
with the SEC in order to add the Class B and Class C shares of that Fund and is
expected to become effective on or about October 15, 2002.

INVESTMENT OBJECTIVES OF EACH FUND

     The investment objective of both the Money Market Fund and the Cash
Investment Fund is to provide as high a level of current interest income as is
consistent with maintaining liquidity and stability of principal. However, the
Money Market Fund's investment objective is "fundamental" and cannot be changed
without a shareholder vote. The Cash Investment Fund's investment objective may
be changed by the Board without shareholder approval. Shareholders of the Cash
Investment Fund would be notified of any such change.

PRIMARY INVESTMENTS OF EACH FUND

     Each Fund seeks to achieve its investment objective by investing in a broad
range of U.S. dollar-denominated money market instruments. Each Fund invests
solely in U.S. 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. Each Fund's investments may include fixed and variable rate
securities.

     As of June 30, 2002, each Fund's portfolio was invested in the same four
basic types of securities in the following percentages:

<Table>

                                        31


PORTFOLIO INSTRUMENTS AND PRACTICES

     Asset-Backed Securities. Subject to applicable maturity and credit
criteria, each Fund may purchase securities backed by mortgages, installment
sales contracts, credit card receivables or other assets. Mortgage-backed
securities carry additional risks. The price and yield of these securities
typically assume that the securities will be redeemed at a given time before
maturity. When interest rates fall substantially, these securities are generally
redeemed early because the underlying mortgages are often prepaid. In that case
a Fund would have to reinvest the money at a lower rate. In addition, the price
or yield of mortgage-backed securities may fall if they are redeemed later than
expected.

     Foreign Securities. Each Fund may invest up to 25% of total assets in U.S.
dollar denominated money market securities of foreign issuers, which include
securities issued by foreign companies and foreign governments and their
agencies, instrumentalities or political subdivisions and supranational
organizations. Investments by a Fund in foreign securities involve risks in
addition to those of U.S. securities, in part because of higher political and
economic risks and because there is less public information available about
foreign companies.

     Guaranteed Investment Contracts. Each Fund may invest in guaranteed
investment contracts. Guaranteed investment contracts are agreements of a Fund
to make payments, generally to an insurance company's general account, in
exchange for a minimum level of interest based on an index. Guaranteed
investment contracts are considered illiquid investments and are acquired
subject to a Fund's limitation on illiquid investments.

     When-Issued Securities, Delayed Delivery Transactions and Forward
Commitments. A purchase of "when-issued" securities refers to a transaction made
conditionally because the securities, although authorized, have not yet been
issued. A delayed delivery or forward commitment transaction involves a contract
to purchase or sell securities for a fixed price at a future date beyond the
customary settlement period. Purchasing or selling securities on a when-issued,
delayed delivery or forward commitment basis involves the risk that the value of
the securities may change by the time they are actually issued or delivered.
These transactions also involve the risk that the seller may fail to deliver the
security or cash on the settlement date.

     Zero Coupon Bonds. These are securities issued at a discount from their
face value because interest payments are typically postponed until maturity. The
market prices of zero coupon bonds generally are more

                                        32


volatile than the market prices of interest-bearing securities and are likely to
respond to a greater degree to changes in interest rates than interest-bearing
securities having similar maturities and credit quality. A Fund's investments in
zero coupon bonds may require the Fund to sell some of its portfolio securities
to generate sufficient cash to satisfy certain income distribution requirements.

     Stripped Securities. These securities are issued by the U.S. Government (or
agency or instrumentality), foreign governments or banks and other financial
institutions. They entitle the holder to receive either interest payments or
principal payments that have been "stripped" from a debt obligation. These
obligations include participations in trusts that hold U.S. Treasury or agency
securities. Stripped securities are very sensitive to changes in interest rates
and to the rate of principal repayments. A rapid or unexpected increase in
mortgage prepayments could severely depress the price of certain stripped
mortgage-backed securities and adversely affect a Fund's total returns.

     Securities Lending. Qualified institutions may borrow portfolio securities
on a short-term basis. By reinvesting any cash collateral received in these
transactions, additional income gains or losses may be realized. Securities
lending may represent no more than 33 1/3% of the value of the Money Market
Fund's total assets (including the loan on collateral) and no more than 25% of
the value of the Cash Investment Fund's total assets (including the loan on
collateral). The main risk when lending Fund securities is that if the borrower
fails to return the securities or the invested collateral has declined in value,
a Fund could lose money. Each Fund's securities lending percentage limitation is
a fundamental investment restriction that may not be changed without a
shareholder vote.

     Borrowing and Reverse Repurchase Agreements. The Funds can borrow money
from banks and enter into reverse repurchase agreements with banks and other
financial institutions. Reverse repurchase agreements involve the sale of
securities held by a Fund subject to the Fund's agreement to repurchase them at
a mutually agreed upon date and price (including interest). Each Fund may borrow
money in an amount up to 5% of its assets for temporary emergency purposes and
in an amount up to 33 1/3% of its assets to meet redemptions. For each Fund,
this is a fundamental policy which can be changed only by shareholders.
Borrowings and reverse repurchase agreements by a Fund may involve leveraging.
If the securities held by the Fund decline in value while these transactions are
outstanding, the Fund's net asset value will decline in value by proportionately
more than the decline in value of the securities. In addition, reverse
repurchase agreements involve the risks that the interest income

                                        33


earned by the Fund (from the investment of the proceeds) will be less than the
interest expense of the transaction, that the market value of the securities
sold by the Fund will decline below the price the Fund is obligated to pay to
repurchase the securities, and that the securities may not be returned to the
Fund.

     Additional Investment Restrictions. In addition to the restrictions
described above, each Fund has adopted certain fundamental investment
restrictions that may be changed only with the approval of a majority of the
outstanding securities (as defined in the 1940 Act) of that Fund. These
restrictions are set forth in the Statement of Additional Information for each
Fund.

RISK FACTORS

     Both the Money Market Fund and the Cash Investment Fund are subject to the
following principal investment risks:

     Credit (or Default) Risk. An issuer of a security may default on its
payment obligations. Also, an issuer may suffer adverse changes in its financial
condition that could lower the credit quality of a security, leading to greater
volatility in the price of the security and in shares of a Fund. A change in the
quality rating of a bond can also affect the bond's liquidity and make it more
difficult for a Fund to sell.

     Interest Rate Risk. An increase in prevailing interest rates will cause
fixed income securities held by a Fund to decline in value. When interest rates
fall, the reverse is true. Longer-term bonds are generally more sensitive to
interest rate changes than shorter-term bonds. Generally, the longer the average
maturity of the bonds held by a Fund, the more the Fund's share price will
fluctuate in response to interest rate changes.

     Prepayment Risk. A Fund may experience losses when an issuer exercises its
right to pay principal on an obligation held by the Fund (such as an
asset-backed security or mortgage-backed security) earlier than expected. This
may happen during a period of declining interest rates. Under these
circumstances, a Fund may be unable to recoup all of its initial investment and
will suffer from having to reinvest in lower yielding securities. The loss of
higher yielding securities and the reinvestment at lower interest rates can
reduce a Fund's income, total return and share price. Rates of prepayment,
faster or slower than expected, could reduce a Fund's yield, increase the
volatility of a Fund and/or cause a decline in net-asset value. Certain types of
mortgage-backed securities, such as collateralized mortgage obligations, may be
more volatile and less liquid than other types.

                              FINANCIAL HIGHLIGHTS

     The financial highlights table is intended to help shareholders understand
each Fund's financial performance for the past 5 years. Certain information
reflects financial results for a single Fund share. The total returns in the
table represent the rate that an investor would have earned (or lost) on an
investment in a particular class of the Fund (assuming reinvestment of all
dividends and distributions). The information has been audited by Ernst & Young
LLP, independent auditors. The independent auditors report, along with each
Fund's financial statements, are included in the annual reports of the Funds,
and are incorporated by reference into the Statement of Additional Information.
You may obtain the annual reports without charge by calling (800) 438-5789.
Financial Highlights for Class B and Class C shares of the Cash Investment Fund
are not provided as those classes had not yet commenced operations as of the
date of this Proxy/Prospectus.

                   HOW TO PURCHASE, SELL AND EXCHANGE SHARES

PURCHASING SHARES

Purchase Price of Shares

     Class A shares, Class B, Class C, and Class Y shares of the Funds are sold
at the net asset value ("NAV") next determined after a purchase order is
received in proper form.

     Broker-dealers or financial advisors (other than the Funds' distributor)
may charge you additional fees for shares you purchase through them.

                                        40


Who May Purchase Class Y Shares

     The following persons may purchase Class Y shares of the Funds:

     - fiduciary and discretionary accounts of institutions;

     - institutional investors (including: banks; savings institutions; credit
       unions and other financial institutions; corporations; foundations;
       pension, profit sharing and employee benefit plans and trusts; insurance
       companies; investment companies; investment advisers, broker-dealers and
       other financial advisors acting for their own accounts or for the
       accounts of their clients);

     - directors, trustees, officers and employees of the Munder Funds, MCM and
       the Funds' distributor;

     - MCM's investment advisory clients; and

     - family members of employees of MCM.

     The Cash Investment Fund also issues Class 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 about
that class.

Policies for Purchasing Shares

     Investment minimums. The minimum initial investment for Class A, Class B
and Class C shares is $2,500 per Fund for all accounts, with the following
exceptions. The minimum initial investment for all types of Individual
Retirement Accounts ("IRAs"), 403(b), Uniform Gifts to Minors Act ("UGMA") and
Uniform Transfers to Minors Act ("UTMA") accounts is $500 per Fund. The minimum
subsequent investment per Fund for all account types is $50. For those investors
who use the Automatic Investment Plan ("AIP"), the minimum initial and
subsequent investment per Fund is $50. We reserve the right to deduct a $6
quarterly fee for all AIP accounts that cease contributions before reaching the
applicable account minimum. Before imposing any such fee we will provide you
with 30 days' advance written notice.

     Investment minimums for Class A, Class B and Class C shares do not apply to
purchases made through certain programs approved by the Funds in which you pay
an asset-based fee for advisory, administrative and/or brokerage services. We
reserve the right to waive any investment minimum. If you wish to invest more
than $250,000, you must purchase Class A or Class C shares.

                                        41


     The minimum initial investment for Class Y shares by fiduciary and
discretionary accounts of institutions and by institutional investors is
$500,000. Other investors are not subject to any minimum. There is no minimum
for subsequent investments.

     Accounts below minimums. If your investment in Class A, Class B or Class C
shares of a Fund does not meet the applicable account minimum (see "Investment
minimums" above), you may increase your balance to that level or that Fund
account may be charged a quarterly servicing fee of $6, which includes the cost
of any applicable CDSC on shares redeemed to pay the fee. The servicing fee is
paid directly to the affected Fund to offset the disproportionately high costs
of servicing accounts with low balances and is intended to benefit shareholders
in the long term. In limited circumstances and subject to our sole discretion,
we may waive the imposition of this fee. We also reserve the right, upon 30
days' advance written notice, to redeem your account (and forward the redemption
proceeds to you) if its value is below the applicable minimum.

Timing of Orders

     Purchase orders must be received by the Funds' distributor, transfer agent
or authorized dealer before the close of regular trading on the NYSE (normally,
4:00 p.m. Eastern time). Purchase orders received after that time will be
accepted as of the next business day.

EXCHANGING SHARES

Policies for Exchanging Shares

     - You may exchange your Fund shares for shares of the same class of other
       Munder Funds based on their relative NAVs.

     - You may exchange Class C shares of the Funds for Class C or Class II
       shares of other Munder Funds, based on their relative NAVs.

     - You may exchange Class A shares of the Cash Investment Fund for Class A,
       Class B or Class C shares of other Munder Funds, based on their relative
       NAVs.

     - 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 Munder Funds for which a sales charge was paid, can be
       exchanged for Class A shares of another Munder Fund at NAV.

     - Class B and Class C shares of the Funds 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 Munder Fund that
       you purchase by exchange.

     - If you are exchanging into shares of a Munder Fund with a higher sales
       charge, you must pay the difference at the time of the exchange.

     - 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 Munder Fund
       you wish to purchase by exchange. You can obtain a
                                        44


       prospectus for any Munder Fund by contacting your broker or calling the
       Munder Funds at (800) 438-5789.

     - Brokers or financial advisors may charge you a fee for handling
       exchanges.

     - We may change, suspend or terminate the exchange privilege at any time.
       You will be given notice of any material modifications except where
       notice is not required.

Methods for Exchanging Shares

     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 requests to your broker, financial
advisor or other financial institution or you may send them directly to the
Funds' transfer agent at The Munder Funds, c/o PFPC Inc., P.O. Box 9701,
Providence, RI 02940, or by overnight delivery, to The Munder Funds, c/o PFPC
Inc., 4400 Computer Drive, Westborough, MA 01581.

REDEEMING SHARES

Redemption Price

     We will redeem shares at the NAV next determined after we receive the
request in proper form. We will reduce the amount you receive by the amount of
any applicable CDSC.

     Please see "How to Purchase, Sell and Exchange Shares -- Distribution
Arrangements" below for information about CDSCs.

Policies for Redeeming Shares

     Class A, Class B or Class C Shares. For your protection, a medallion
signature guarantee is required for the following shares redemption requests:

     - redemption proceeds greater than $50,000;

     - redemption proceeds not being made payable to the record owner of the
       account;

                                        45


     - redemption proceeds not being mailed to the address of record on the
       account;

     - if the redemption proceeds are being transferred to another Munder Fund
       account with a different registration;

     - change in ownership or registration of the account; or

     - changes to banking information without a voided check being supplied.

     When a Fund requires a signature guarantee, a medallion signature guarantee
must be provided. Failure to follow this policy will result in a delay in
processing your redemption request.

     A medallion signature guarantee may be obtained from a domestic bank or
trust company, broker, dealer, clearing agency, savings association, or other
financial institution which is participating in a medallion program recognized
by the Securities Transfer Association. The three recognized medallion programs
are Securities Transfer Agents Medallion Program ("STAMP"), Stock Exchanges
Medallion Program ("SEMP") and New York Stock Exchange, Inc. Medallion Signature
Program ("NYSE MSP"). Signature guarantees from financial institutions which are
not participating in one of these programs will not be accepted.

     Class Y 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 that institution.

Methods for Redeeming Shares

     Class A, Class B or Class C Shares. You may redeem Class A, Class B or
Class C shares of the Funds in several ways:

     - By Mail. You may mail your redemption request to: The Munder Funds, c/o
       PFPC Inc., P.O. Box 9701, Providence, RI 02940, or by overnight delivery,
       to The Munder Funds, c/o PFPC Inc., 4400 Computer Drive, Westborough, MA
       01581. 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.

     - By Telephone. You can redeem your shares by contacting your broker or
       your financial advisor, or by calling the Funds at (800) 438-5789. There
       is no minimum requirement for telephone redemptions.

                                        46


       If you are redeeming at least $1,000 of shares and you have authorized
       expedited redemption on your account application form, simply call the
       Funds prior to 4:00 p.m. (Eastern time), and request the redemption
       proceeds be wired to the commercial bank, registered broker-dealer or
       financial advisor you designated on your account application form. We
       will send your redemption proceeds to you on the next business day. We
       reserve the right at any time to change or impose fees for this expedited
       redemption procedure.

       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.

     - You may redeem shares through the Systematic Withdrawal Plan.

     - Free Checkwriting is available to holders of Class A shares of the Funds.

     Class Y Shares. You may redeem Class Y shares of the Funds through your
bank, financial advisor or other financial institution. You may redeem a portion
of your shares of the Funds through the free checkwriting privilege.

     If we receive a redemption order for either Fund before 12:00 noon (Eastern
time), we will normally wire payment to the redeeming institution on the same
business day. If an order for either Fund is received between 12:00 noon and
4:00 p.m. (Eastern time), payment is normally wired the next business day.

ADDITIONAL POLICIES FOR PURCHASES, EXCHANGES AND REDEMPTIONS

All Share Classes

     - We consider purchase, exchange or redemption orders to be in "proper
       form" when all required documents are properly completed, signed and
       received. We may reject any requests that are not in proper form.

     - The Funds reserve the right to reject any purchase order, including
       exchanges from other Munder Funds.

     - At any time, the Funds may change any of their purchase, redemption or
       exchange practices, and may suspend the sale of their shares.

                                        47


     - The Funds may delay sending redemption proceeds for up to seven days, or
       longer if permitted by the SEC.

     - 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.

     - To limit the Funds' expenses, we no longer issue share certificates.

     - A Fund may temporarily stop redeeming shares if:

          - the NYSE is closed;

          - trading on the NYSE is restricted;

          - 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.

     - If accepted by a Fund, investors may purchase shares of the Fund with
       securities which the Fund may hold. MCM will determine if the securities
       are consistent with the Fund's objectives and policies. If accepted, the
       securities will be valued the same way the Fund values portfolio
       securities it already owns. Call the Funds at (800) 438-5789 for more
       information.

     - The Funds reserve the right to make payment for redeemed shares wholly or
       in part by giving the redeeming shareholder portfolio securities. The
       shareholder may pay transaction costs to dispose of these securities.

     - We record all telephone calls for your protection and take measures to
       identify the caller. As long as the Funds' transfer agent takes
       reasonable measures to authenticate telephone requests on an investor's
       account, neither the Funds, the Funds' distributor nor the transfer agent
       will be held responsible for any losses resulting from unauthorized
       transactions.

     - If you purchased shares directly from the Funds, the Funds' 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, investment professional or
       institution, account activity will be detailed in their statements to
       you.

                                        48


Class A, B and C Shares

     - We may redeem your account if its value falls below the minimum initial
       investment 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.

Class Y Shares

     - For Class Y shares, we may redeem your account if its value falls below
       $2,500 upon 30 days' advance written notice. Financial institutions are
       responsible for transmitting orders and payments for their customers with
       regard to Class Y shares on a timely basis.

SHAREHOLDER PRIVILEGES

     Automatic Investment Plan ("AIP"). Under the AIP you may arrange for
periodic investments in Class A, Class B, Class C or Class Y shares of 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.

     Systematic Withdrawal Plan ("SWP"). If you have an account value of $2,500
or more in Class A, Class B or Class C shares of 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 SWP by completing the SWP
application form available through the transfer agent. To participate in the SWP
you must have your dividends automatically reinvested and may not hold share
certificates. You may change or cancel the SWP at any time upon notice to the
Funds' transfer agent. You should not buy Class A shares (and pay a sales
charge) while you participate in the SWP and you must pay any applicable CDSC
when you redeem shares.

     Free Checkwriting. Free checkwriting is available to holders of Class A and
Class Y shares of the Funds who complete a checkwriting authorization form and
return it to the Funds' transfer agent. 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.

                                        49


DISTRIBUTION ARRANGEMENTS

Share Class Selection

     The Funds both offer Class A, Class B, Class C and Class Y 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, including
applicable distribution and/or shareholder servicing fees as described in the
section entitled "12b-1 Fees," and any initial sales charge or CDSC in
estimating the costs of investing in a particular class of shares.

Class A Shares

     - Although there is no front-end sales charge on the Funds, other Munder
       Funds offering Class A shares are subject to such charges. There are
       several ways to reduce these charges.

     - Lower annual expenses than Class B and Class C shares.

Class B Shares

     - No front-end sales charge. All your money goes to work for you right
       away.

     - A CDSC on shares you sell within six years of purchase.

     - Higher annual expenses than Class A shares.

     - Automatic conversion to Class A shares approximately eight years after
       issuance, thus reducing future annual expenses. If you acquired Class B
       shares of the Money Market Fund before November 8, 2000 or if you
       acquired Class B shares of the Money Market Fund or Cash Investment Fund
       by exchanging shares of another Munder Fund that you purchased before
       November 8, 2000, your shares will convert automatically six years after
       issuance of the original purchase.

     - CDSC is waived for certain redemptions.

Class C Shares

     - No front-end sales charge. All your money goes to work for you right
       away.

     - A CDSC on shares you sell within one year of purchase.

                                        50


     - Higher annual expenses than Class A shares.

     - Shares do not convert to another class.

Class Y Shares (Only available to certain eligible investors)

     - No front end sales charge. All your money goes to work for you right
       away.

     - Lower annual expenses than Class A, Class B and Class C shares.

     The Cash Investment Fund also issues Class K shares, which have different
sales charges, expense levels and performance. Class K shares carry no sales
charges, have no conversion feature and have lower annual expenses than other
share classes. Class K shares are only available to certain eligible investors.

CDSC

     You pay a CDSC when you redeem:

     - Class A shares of the Money Market Fund that were acquired through the
       exchange of Class A shares of another Munder Fund purchased within one
       year of redemption as part of an investment of $1,000,000 or more;

     - Class A shares of the Cash Investment Fund that were acquired after
       October 31, 2002, through the exchange of Class A shares of another
       Munder Fund purchased within one year of redemption as part of an
       investment of $1,000,000 or more;

     - Class B shares of the Funds within six years of buying them;

     - Class C shares of the Funds within one year of buying them;

     These time periods include the time you held the shares you exchanged to
acquire Fund shares. The CDSC for Class C shares, if applicable, is 1%.

     The CDSC schedule for Class B shares of the Funds is set forth below. The
CDSC is calculated based on the original NAV at the time of your investment or
the NAV at the time of redemption, whichever is lower.

                                        51


Shares purchased through reinvestment of distributions are not subject to a
CDSC.

<Table>
<Caption>
       YEAR SINCE
        PURCHASE            CDSC %
       ----------           ------
                         
First                         5%
Second                        4%
Third                         3%
Fourth                        3%
Fifth                         2%
Sixth                         1%
Seventh and thereafter        0%
</Table>

     If you sell some but not all of your shares, certain shares not subject to
a CDSC (i.e., shares purchased with reinvested dividends) will be redeemed
first, followed by shares subject to the lowest CDSC (typically shares held for
the longest time).

     For example, assume an investor purchased 1,000 shares at $10 a share (for
a total cost of $10,000). Three years later, the shares have a net asset value
of $12 per share and during that time, the investor acquired 100 additional
shares through dividend reinvestment. If the investor then makes one redemption
of 500 shares (resulting in proceeds of $6,000,500 shares X $12 per share), the
first 100 shares redeemed will not be subject to the CDSC because they were
acquired through reinvestment of dividends. With respect to the remaining 400
shares redeemed, the CDSC is charged at $10 per share (because the original
purchase price of $10 per share is lower than the current net asset value of $12
per share). Therefore, only $4,000 of the $6,000 such investor received from
selling his or her shares will be subject to the CDSC, at a rate of 3.00% (the
applicable rate in the third year after purchase).

CDSC Waivers

     We will waive the CDSC payable upon redemptions of Class B shares of the
Funds which you purchased 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; and

                                        52


     - redemptions limited to 10% per year of an account's NAV if taken by SWP.
       For example, if your balance on December 31st is $10,000, you can redeem
       up to $1,000 that following year free of charge through SWP.

     We will waive the CDSC payable upon redemptions of Class B shares which you
purchased after December 1, 1998 (or acquired through an exchange of shares of
another Munder Fund purchased after December 1, 1998) for:

     - redemptions made from an IRA or other individual retirement plan account
       established through Comerica Securities, Inc. after you reach age 59 1/2
       and after the eighteen month anniversary of the purchase of Fund shares.

12B-1 FEES

     The Funds have adopted a Distribution and Service Plan with respect to
their Class A, Class B and Class C shares that allows each Fund to pay
distribution and other fees for the sale of its shares and for services provided
to shareholders. Under the plan, the Funds may pay up to 0.25% of the daily net
assets of Class A, Class B and Class C shares to pay for certain shareholder
services provided by institutions that have agreements with the Funds or their
service providers to provide such services. The Funds may also pay up to 0.75%
of the daily net assets of the Class B and Class C shares to finance activities
relating to the distribution of their shares.

     Because the fees are paid out of each Fund's assets on an on-going basis,
over time these fees will increase the cost of an investment in a Fund and may
cost a shareholder more than paying other types of sales charges.

OTHER INFORMATION

     In addition to paying 12b-1 fees or service fees, the Funds may pay banks,
broker-dealers, financial advisors or other financial institutions fees for
sub-administration, sub-transfer agency and other shareholder services
associated with shareholders whose shares are held of record in omnibus or other
group accounts. The Funds' service providers, or any of their affiliates, may,
from time to time, make these types of payment or payments for other shareholder
services or distribution, out of their own resources and without additional cost
to the Funds or their shareholders. Please note that Comerica Bank, an affiliate
of MCM, receives a fee from the Funds for providing shareholder services to its
customers who own shares of the Funds.

PRICING OF FUND SHARES

     Each Fund's NAV is calculated on each day the NYSE is open. The NAV per
share is the value of a single Fund share. Each Fund calculates NAV separately
for each class. The NAV is calculated by (1) taking the current value of a
Fund's total assets allocated to a particular class of shares, (2) subtracting
the liabilities and expenses charged to that class, and (3) dividing that amount
by the total number of shares of that class outstanding.

     The Funds calculate NAV as of the close of regular trading on the NYSE,
normally 4:00 p.m. (Eastern time). If the NYSE closes at any other time, or if
an emergency exists, transaction deadlines and NAV calculations may occur at
different times. The Funds' assets may be priced and the Funds may be open for
business on weekdays when the NYSE is closed, but the Federal Reserve Bank in
Boston is open. Purchase and redemption orders received and accepted prior to
4:00 p.m., Eastern time, on any day the money markets are open but the NYSE is
closed will be effected at the net asset value per share of the applicable class
of shares of the Fund determined as of 4:00 p.m., Eastern time, on that date. To
the extent that other Munder Funds are not open for business, no shareholder
exchange activity will be permitted with such other Funds on such days. The NAV
of each Fund is generally based on the current market value of the securities
held in the Fund.

     In determining each Fund's NAV, securities are valued at amortized cost,
which is approximately equal to market value. 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.

DISTRIBUTIONS

     As a shareholder, you are entitled to your share of a Fund's net income and
gains on its investments. A Fund passes substantially all of its earnings along
to its shareholders as distributions. When a Fund earns dividends from stocks
and interest from debt securities and distributes these earnings to
shareholders, it is called a dividend distribution. A Fund realizes capital
gains when it sells securities for a higher price than it paid. When these gains
are distributed to shareholders, it is called a capital gain distribution.

     The Funds declare dividends daily and pay the monthly. Both Funds
distribute their net realized capital gains, if any, at least annually. Each
Fund will pay distributions in additional shares of the same class of that

                                        54


Fund. If you wish to receive distributions in cash, either indicate this request
on your account application form or notify the Funds by calling (800) 438-5789.

     If a purchase order for the Money Market Fund is accepted before 12:00 p.m.
(Eastern time), the investor will receive dividends for that day. If a purchase
order for the Cash Investment Fund is accepted before 2:45 p.m. (Eastern time),
the investor will receive dividends for that day. Otherwise the investor will
begin to earn dividends on the first business day following the day of purchase.

     If a redemption for the Money Market Fund is received before 12:00 p.m.
(Eastern time), the redeeming shareholders will not receive dividends for that
day. If a redemption order for the Cash Investment Fund is received before 2:45
p.m. (Eastern time), the redeeming shareholder will not receive dividends for
that day.

     It is possible that a Fund may make a distribution in excess of the Fund's
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.

FEDERAL TAX CONSEQUENCES

     Investments in a Fund may have tax consequences that you should consider.
This section briefly describes some of the more common federal tax consequences.
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 Statement of Additional Information, which is
available to you upon request. You should consult your tax advisor about your
own particular tax situation.

     Taxes on Distributions. You will generally have to pay federal income tax
on all Fund distributions. Distributions will be taxed in the same manner
whether you receive the distributions in cash or in additional shares of the
Fund. Shareholders not subject to tax on their income, generally will not be
required to pay any tax on distributions.

     Distributions that are derived from net long-term capital gains generally
will be taxed as long-term capital gains. However, neither the Money Market Fund
nor the Cash Investment Fund expects to distribute any long-term capital gain.
Dividend distributions and distributions of short-term capital gains generally
will be taxed as ordinary income.
                                        55


     Distributions are generally taxable to you in the tax year in which they
are paid, with one exception: distributions declared in October, November or
December, but not paid until January of the following year, are taxed as though
they were paid on December 31 in the year in which they were declared.

     Shareholders generally are required to report all Fund distributions on
their federal income tax returns. Each year the Funds will send you information
detailing the amount of ordinary income and capital gains paid to you for the
previous year.

     Taxes on Sales or Exchanges. If the shares of the Money Market Fund and the
shares of the Cash Investment Fund maintain at all relevant times a net asset
value of $1.00 per share (as is expected), then if you sell such shares or
exchange them for shares of another Munder Fund, you generally will not
recognize taxable gain or loss.

 INFORMATION ABOUT MANAGEMENT OF THE MONEY MARKET FUND AND THE CASH INVESTMENT
                                      FUND

INVESTMENT ADVISER

     Munder Capital Management ("MCM"), 480 Pierce Street, Birmingham, Michigan
48009, is the investment adviser of each Fund. As of June 30, 2002, MCM managed
over $31.2 billion of assets for various institutional clients, including
investment companies, pension and profit sharing funds, foundations and
insurance companies, as well as for high net worth individuals. Of this amount,
approximately $15.0 billion was invested in equity securities, $8.8 billion were
invested in money market or other short-term instruments, $6.3 billion were
invested in other fixed income securities and $1.4 billion were invested in
balanced investments.

     MCM provides overall investment management for the Funds, provides research
and credit analysis and is responsible for all purchases and sales of portfolio
securities.

     During the fiscal year ended June 30, 2002, the Cash Investment Fund paid
an advisory fee at an annual rate of 0.35% of the average daily net assets of
the Fund and the Money Market Fund paid an advisory fee at an annual rate of
0.40% of the average daily net assets of the Fund.

                COMPARATIVE INFORMATION ON SHAREHOLDERS' RIGHTS

     The Company is a Maryland corporation and is governed by its Articles of
Incorporation, By-Laws and Board of Directors. The Trust is a Massachusetts
business trust and is governed by a Declaration of Trust, By-Laws and a Board of
Trustees. Both the Money Market Fund and the Cash Investment Fund are also
governed by applicable state and Federal law. Certain differences and
similarities between the two Funds are summarized below.

SHAREHOLDER LIABILITY

     The Money Market Fund is organized as a series of a Maryland corporation,
and it shareholders generally have no personal liability for its acts or
obligations. The Cash Investment Fund is organized as a series under
Massachusetts law, shareholders of a Massachusetts business trust could, under
certain circumstances, be held personally liable for the obligations of the
trust. However, the Declaration of Trust for the Trust states that shareholders
will not be subject to any personal liability in connection with the assets of
the Trust for the acts or obligations of the Trust. The Declaration of Trust
provides for indemnification out of the assets belonging to the respective
series of the Trust with respect to which such shareholder's shares are issued,
for all losses and expenses of any shareholder held personally liable for the
obligations of the Trust solely by reason of his or her being or having been a
shareholder. Thus, the risk of a shareholder incurring financial loss on account
of shareholder liability is considered remote since it is limited to
circumstances in which a disclaimer is inoperative and the Fund itself would be
unable to meet its obligations.

VOTING RIGHTS

     Neither the Money Market Fund nor the Cash Investment Fund holds annual
meetings of shareholders, although each may hold special meetings for purposes
of voting on certain matters as required under the 1940 Act. Special meetings of
shareholders of either Fund may be called upon the written request of holders of
not less than 10% of that Fund's then outstanding voting securities. On each
matter submitted to a vote of the shareholders of the Money Market Fund or the
Cash Investment Fund, each shareholder is entitled to one vote for each whole
share owned and a proportionate fractional vote for any fractional share
outstanding in the shareholder's name on the Fund's books. Shareholders of all
classes of each Fund vote together as a Fund, and not by class, except as
otherwise

                                        57


required by applicable law or by that Fund's charter documents, or when the
matter affects only the interests of a particular class.

LIQUIDATION OR DISSOLUTION

     In the event of the liquidation or dissolution of either the Money Market
Fund or the Cash Investment Fund, the shareholders of that Fund are entitled to
receive, when and as declared by the Boards of Directors/ Trustees of the
Company or the Trust, respectively, the excess of the assets over the
liabilities belonging to the Fund. The assets so distributed to shareholders of
a Fund would be distributed among the shareholders in proportion to the number
of shares of that Fund held by them and recorded on the books of the Fund.

LIABILITY OF DIRECTORS/TRUSTEES

     The By-laws of the Company provide that the Company will indemnify
Directors and officers of the Company to the fullest extent permitted by
Maryland law and the 1940 Act. The Declaration of Trust of the Trust provides
for indemnification of its trustees and officers. However, the By-laws and the
Declaration of Trust do not purport to protect or indemnify a trustee or officer
against any liability to which such person would otherwise be subject by reason
of willful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of such person's office.

RIGHTS OF INSPECTION

     Except as required by Maryland law, shareholders of the Money Market Fund
have only such right to inspect the records, documents, accounts and books of
the Fund as may be granted by the Directors of the Company. Maryland corporate
law provides that one or more persons who together have owned at least 5% of the
outstanding shares of the Money Market Fund for at least 6 months may, on
written request, inspect during usual business hours the books of account and
stock ledger of the Money Market Fund. Shareholders of the Cash Investment Fund
generally have the right to inspect the records, accounts and books of the
Trust, as such right is permitted shareholders of a Massachusetts business trust
under Massachusetts corporation law. Currently, each shareholder of a
Massachusetts business trust is permitted to inspect the records, accounts and
books of a corporation for any legitimate business purpose relative to the
affairs of the corporation.

                                        58


     The foregoing is only a summary of certain characteristics of the
operations of the Money Market Fund, the Articles of Incorporation and By-laws
of the Company and Maryland law and the Cash Investment Fund, the Declarations
of Trust of the Trust, and Massachusetts law. The foregoing is not a complete
description of the documents cited. Shareholders should refer to the provisions
of such documents and state laws governing each Fund for a more thorough
description.

                                 OTHER BUSINESS

     The Board does not intend to present any other business at the Meeting. If,
however, any other matters are properly brought before the Meeting, the persons
named in the accompanying form of proxy will vote thereon in accordance with
their judgment.

                               VOTING INFORMATION

     This Proxy Statement/Prospectus is furnished in connection with a
solicitation of proxies by the Board to be used at the Meeting. This Proxy
Statement/Prospectus, along with a Notice of the Meeting and a proxy card, is
first being mailed to shareholders of the Money Market Fund on or about October
7, 2002. Only shareholders of record as of the close of business on the Record
Date, October 1, 2002, will be entitled to notice of, and to vote at, the
Meeting. If the enclosed form of proxy card is properly executed and returned in
time to be voted at the Meeting, the proxies named therein will vote the shares
represented by the proxy in accordance with the instructions marked thereon.
Unmarked but properly executed proxy cards will be voted FOR the proposed
Reorganization and FOR any other matters deemed appropriate.

     A proxy may be revoked at any time on or before the Meeting by written
notice to the Secretary of the Company at the address on the cover of this Proxy
Statement/Prospectus or by attending and voting at the Meeting. Unless revoked,
all valid and executed proxies will be voted in accordance with the
specifications thereon or, in the absence of such specifications, for approval
of the Reorganization Agreement and the Reorganization contemplated thereby.

PROXY SOLICITATION

     Proxies are solicited by mail. Additional solicitations may be made by
telephone, e-mail, or other personal contact by officers or employees of MCM and
its affiliates or by proxy soliciting firms retained by MCM. MCM has retained
Georgeson Shareholder Communications, Inc. ("Georgeson") to provide proxy
solicitation services in connection with the Meeting at an estimated cost of
$22,000. In addition, MCM may reimburse persons holding shares in their names or
names of their nominees for

                                        60


expenses incurred in forwarding solicitation material to their beneficial
owners. The cost of the solicitation will be borne by MCM.

     As the meeting date approaches, shareholders of the Money Market Fund may
receive a call from a representative of Georgeson if the Fund has not yet
received its vote. Authorization to permit Georgeson to execute proxies may be
obtained by telephonic or electronically transmitted instructions from
shareholders of the Money Market Fund. Proxies that are obtained telephonically
will be recorded in accordance with the procedures set forth below. Management
of the Money Market Fund believes that these procedures are reasonably designed
to ensure that the identity of the shareholder casting the vote is accurately
determined and that the voting instructions of the shareholder are accurately
determined. In all cases where a telephonic proxy is solicited, the Georgeson
representative is required to ask the shareholder for the shareholder's full
name, address, social security number or employer identification number, title
(if the person giving the proxy is authorized to act on behalf of an entity,
such as a corporation), the number of shares owned and to confirm that the
shareholder has received this Proxy Statement/Prospectus in the mail.

     If the shareholder information solicited agrees with the information
provided to Georgeson by the Money Market Fund, the Georgeson representative has
the responsibility to explain the process, read the proposals listed on the
proxy card, and ask for the shareholder's instructions on each proposal. The
Georgeson representative, although permitted to answer questions about the
process, is not permitted to recommend to the shareholder how to vote, other
than to read any recommendation set forth in this Proxy Statement/Prospectus.
Georgeson will record the shareholder's instructions on the card. Within 72
hours, Georgeson will send the shareholder a letter or mailgram to confirm the
shareholder's vote and asking the shareholder to call Georgeson immediately if
the shareholder's instructions are not correctly reflected in the confirmation.

QUORUM

     The holders of one-third of the shares of the Money Market Fund that are
outstanding at the close of business on the Record Date and are present in
person or represented by proxy will constitute a quorum for the Meeting.

VOTE REQUIRED

     Approval of the Reorganization Agreement will require the affirmative vote
of a majority of the outstanding shares of the Money Market Fund, with all
classes voting together and not by class. Shareholders of the Money
                                        61


Market Fund are entitled to one vote for each share. Fractional shares are
entitled to proportional voting rights.

EFFECT OF ABSTENTIONS AND BROKER "NON-VOTES"

     For purposes of determining the presence of a quorum for transacting
business at the Meeting, executed proxies marked as abstentions and broker
"non-votes" (that is, proxies from brokers or nominees indicating that such
persons have not received instructions from the beneficial owner or other
persons entitled to vote shares on a particular matter with respect to which the
brokers or nominees do not have discretionary power) will be treated as shares
that are present for quorum purposes but which have not been voted. As a result,
such abstentions and broker "non-votes" will have the effect of a vote against
the Reorganization Agreement.

ADJOURNMENTS

     In the event that sufficient votes to approve the Reorganization are not
received to approve the proposal, the persons named as proxies may propose one
or more adjournments of the Meeting to permit further solicitation of proxies.
Any such adjournment will require an affirmative vote by the holders of a
majority of the shares present in person or by proxy and entitled to vote at the
Meeting. In determining whether to adjourn the Meeting, the following factors
may be considered: the percentage of votes actually cast, the percentage of
negative votes actually cast, the nature of any further solicitation and the
information to be provided to shareholders with respect to the reasons for the
solicitation. Generally, votes cast in favor of a proposal will be voted in
favor of adjournment while votes cast against a proposal will be voted against
adjournment. The persons named as proxies will vote upon such adjournment after
consideration of the best interests of all shareholders.

                                        62

     The Company has been advised by Comerica Bank and Munder Fund of Funds,
each an affiliate of MCM, that each intends to vote the shares of the Money
Market Fund over which it has voting power FOR and AGAINST each proposal at the
Meeting in the same proportions as the total votes that are cast FOR and AGAINST
that proposal by other shareholders of the Money Market Fund. [Comerica Bank's
economic interest in such shares, which are primarily held for the benefit of
its customers, is less than 1%.]

     [As of the Record Date, the officers and Directors of the Company
beneficially owned as a group less than 1% of the outstanding shares of the
Money Market Fund. As of the Record Date, the officers and Trustees of the Trust
beneficially owned as a group less than 1% of the outstanding shares of the Cash
Investment Fund.]

     The votes of the shareholders of the Cash Investment Fund are not being
solicited since their approval or consent is not necessary for the
Reorganization to take place.

                             THE MUNDER FUNDS TRUST

                  FORM OF AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION ("Agreement") is made as of this

     This Agreement is intended to be and is adopted as a plan of reorganization

Internal Revenue Code of 1986, as amended ("Code"). The reorganization and
liquidation will consist of the transfer of all of the assets of the Acquired

Acquiring Fund ("Acquiring Fund Shares"), the assumption by the Acquiring Fund
of all liabilities of the Acquired Fund, and the distribution of the Acquiring
Fund Shares to the shareholders of the Acquired Fund in complete liquidation of
the Acquired Fund, as provided herein ("Reorganization"), all upon the terms and
conditions hereinafter set forth in this Agreement.

open-end, registered investment company of the management type and the Acquired
Fund owns securities that generally are assets of the character in which the
Acquiring Fund is permitted to invest;

     WHEREAS, the Trustees of the Trust have determined, with respect to the
Acquiring Fund, that the exchange of all of the assets of the Acquired Fund for
Acquiring Fund Shares and the assumption of all liabilities of the Acquired Fund
by the Acquiring Fund is in the best interests of the Acquiring Fund and its
shareholders and that the interests of the existing shareholders of the

1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND TO THE ACQUIRING FUND IN EXCHANGE
     FOR ACQUIRING FUND SHARES, THE ASSUMPTION OF ALL ACQUIRED FUND LIABILITIES
     AND THE LIQUIDATION OF THE ACQUIRED FUND

     1.1.  Subject to the requisite approval of the Acquired Fund shareholders
and the other terms and conditions herein set forth and on the basis of the
representations and warranties contained herein, the Acquired Fund agrees to
transfer all of the Acquired Fund's assets, as set forth in paragraph 1.2, to
the Acquiring Fund, and the Acquiring Fund agrees in exchange therefor: (i) to
deliver to the Acquired Fund the number of full and fractional Class A, Class B,
Class C and Class Y Acquiring Fund Shares, determined by dividing the value of
the Acquired Fund's net assets with respect to each corresponding class (Class
A, Class B, Class C and Class Y, respectively), computed in the manner and as of
the time and date set forth in paragraph 2.1, by the net asset value of one
Acquiring Fund Share of the corresponding class, computed in the manner and as
of the time and date set forth in paragraph 2.2; and (ii) to assume all
liabilities of the Acquired Fund, as set forth in paragraph 1.3. Such
transactions shall take place on the date of the closing provided for in
paragraph 3.1 ("Closing Date").

shall consist of all assets and property, including, without limitation, all
cash, securities, commodities and futures interests and dividends or interests
receivable that are owned by the Acquired Fund and any deferred or prepaid
expenses shown as an asset on the books of the Acquired Fund on the Closing Date
(collectively, "Assets").

     1.3.  The Acquired Fund will endeavor to discharge all of its known
liabilities and obligations prior to the Closing Date. The Acquiring Fund shall
also assume all of the liabilities of the Acquired Fund, whether accrued or
contingent, known or unknown, existing at the Valuation Date as defined in

                                       A-2


practicable prior to the Closing Date, the Acquired Fund will declare and pay to
its shareholders of record one or more dividends and/or other distributions so
that it will have distributed substantially all (and in no event less than 98%)
of its investment company taxable income (computed without regard to any
deduction for dividends paid) and realized net capital gain, if any, for the
current taxable year through the Closing Date.

     1.4.  Immediately after the transfer of assets provided for in paragraph
1.1, the Acquired Fund will distribute to the Acquired Fund's shareholders of
record with respect to each class of its shares, determined as of immediately
after the close of business on the Closing Date ("Acquired Fund Shareholders"),
on a pro rata basis within that class, the Acquiring Fund Shares of the
corresponding class received by the Acquired Fund pursuant to paragraph 1.1, and
will completely liquidate. Such distribution and liquidation will be
accomplished, with respect to each class of the Acquired Fund's shares, by the
transfer of the Acquiring Fund Shares then credited to the account of the
Acquired Fund on the books of the Acquiring Fund to open accounts on the share
records of the Acquiring Fund in the names of the Acquired Fund Shareholders.
The aggregate net asset value of Class A, Class B, Class C and Class Y Acquiring
Fund Shares to be so credited to Class A, Class B, Class C and Class Y Acquired
Fund Shareholders, respectively, shall, with respect to each class, be equal to
the aggregate net asset value of the shares of common stock ($0.01 par value per
share) of the Acquired Fund ("Acquired Fund Shares") of the corresponding class
owned by Acquired Fund Shareholders on the Closing Date. All issued and
outstanding shares of the Acquired Fund will simultaneously be canceled on the
books of the Acquired Fund, although shares certificates representing interests
in Class A, Class B, Class C and Class Y shares of the Acquired Fund will
represent a number of the corresponding class of Acquiring Fund Shares after the
Closing Date, as determined in accordance with Section 2.3. The Acquiring Fund
shall not issue certificates representing the Class A, Class B, Class C and
Class Y Acquiring Fund Shares in connection with such exchange.

     1.5.  Ownership of Acquiring Fund Shares will be shown on the books of the
Acquiring Fund's Transfer Agent, as defined in paragraph 3.3.

     1.6.  Any reporting responsibility of the Acquired Fund including, but not
limited to, the responsibility for filing regulatory reports, tax returns, or
other documents with the Securities and Exchange Commission ("Commission"), any
state securities commission, and any Federal, state or local tax authorities or
any other relevant regulatory authority, is and shall remain the responsibility
of the Acquired Fund.

                                       A-3


     VALUATION

     1.7.  The value of the Assets shall be the value of such Assets computed as
of immediately after the close of business of the New York Stock Exchange and
after the declaration of any dividends on the Closing Date (such time and date
being hereinafter called the "Valuation Date"), using the valuation procedures
set forth in then-current prospectus and statement of additional information
with respect to the Acquired Fund, and valuation procedures established by the
Acquired Fund's Board of Trustees.

     1.8.  The net asset value of a Class A, Class B, Class C and Class Y
Acquiring Fund Share shall be the net asset value per share computed with
respect to that class as of the Valuation Date, using the valuation procedures
set forth in the Acquiring Fund's then-current prospectus and statement of
additional information, and valuation procedures established by the Acquiring
Fund's Board of Directors.

     1.9.  The number of the Class A, Class B, Class C and Class Y Acquiring
Fund Shares to be issued (including fractional shares, if any) in exchange for
the Acquired Fund's Assets shall be determined with respect to each such class
by dividing the value of the net assets with respect to the Class A, Class B,
Class C and Class Y of the Acquired Fund, as the case may be, determined using
the same valuation procedures referred to in paragraph 2.1, by the net asset
value of an Acquiring Fund Share, determined in accordance with paragraph 2.2.

     1.10.  All computations of value shall be made by State Street Bank and
Trust Company, in its capacity as administrator for the Acquired Fund and the
Acquiring Fund and shall be subject to confirmation by each Fund's record
keeping agent and by each Fund's independent accountants.

2.   CLOSING AND CLOSING DATE

been made. The Acquired Fund's portfolio securities represented by a certificate
or other written instrument shall be presented by the Custodian to those persons
at the Custodian who have primary responsibility for the safekeeping of the
assets of the Acquiring Fund since the Custodian also serves as the custodian
for the Acquiring Fund. Such presentation shall be made for examination no later
than five business days preceding the Closing Date, and shall be transferred and
delivered by the Acquired Fund as of the Closing Date for the account of the
Acquiring Fund duly endorsed in proper form for transfer in such condition as to
constitute good delivery thereof. The Custodian shall deliver to those persons
at the Custodian who have primary responsibility for the safekeeping of the
assets of the Acquiring Fund as of the Closing Date by book entry, in accordance
with the customary practices of the Custodian and of each securities depository,
as defined in Rule 17f-4 under the Investment Company Act of 1940, as amended

party shall deliver to the other such bills of sale, checks, assignments, share
certificates, if any, receipts or other documents as such other party or its
counsel may reasonably request.

     2.4.  In the event that on the Valuation Date (a) the New York Stock
Exchange or another primary trading market for portfolio securities of the
Acquiring Fund or the Acquired Fund (each, an "Exchange") shall be closed to
trading or trading thereupon shall be restricted, or (b) trading or the
reporting of trading on such Exchange or elsewhere shall be disrupted so that,
in the judgment of either the Board of Trustees of the Trust or the Board of
Directors of the Company, accurate appraisal of the value of the net assets of
the Acquiring Fund or the Acquired Fund, respectively, is impracticable, the
Closing Date shall be postponed until the first business day after the day when
trading shall have been fully resumed and reporting shall have been restored.
