Three fund families come together

This summer, the Boards of Directors of Firstar Funds, Inc. and Mercantile
Mutual Funds, Inc. and the Board of Trustees of Firstar Stellar Funds approved a
plan to combine the Three Fund families together to form Firstar Funds. For
shareholders, the proposed consolidation provides several benefit and Firstar
select funds:

 .  A larger group of funds with a wider spectrum of investment styles to choose
   from
 .  Enhanced research capabilities thanks to pooled resources
 .  Investors will need to look to only one name when searching for information
   on their investments - Firstar Funds

If approved by shareholders of the fund families involved, the reorganization is
scheduled to take place in late November. Under the proposed plan, some of the
funds with similar objectives would be combined with existing Firstar Funds,
while other funds would be reorganized into a Firstar fund specifically created
to continue the fund under the Firstar name.

While the names may change, rest assured that each fund will still be expertly
managed with the same disciplined approach you've come to rely on. The portfolio
managers are the investment professionals from Firstar Investment Research and
Management Company, LLC (FIRMCO), Firstar Bank, N.A.'s Capital Management
department and Mississippi Valley Advisors Inc., which have already been
combined and will become Firstar Capital Management, LLC.

The new Firstar Funds family will offer 36 portfolios with varying investment
objectives and styles. You'll find the entire suggested lineup of funds listed
in the charts featured in this brochure.

Dear Shareholder:

   On behalf of the Board of Directors of Mercantile Mutual Funds, Inc.
("Mercantile"), we are pleased to invite you to a special meeting of
shareholders of the Mercantile Portfolios named above (each a "Mercantile Fund")
to be held at 10:00 a.m. (Eastern time) on November 8, 2000 at the offices of
Mercantile's counsel, Drinker Biddle & Reath LLP, One Logan Square, 18/th/ and
Cherry Streets, Philadelphia, Pennsylvania (the "Special Meeting").  At the
Special Meeting, you will be asked to approve a proposed Agreement and Plan of
Reorganization, dated as of _________________ __, 2000 (the "Reorganization
Agreement"), by and between Mercantile and Firstar Funds, Inc. ("Firstar"),
which contemplates the reorganization of your Mercantile Fund into a
corresponding fund of Firstar (each a "Firstar Fund").
<PAGE>

   Background.  As you may recall, Mercantile Bancorporation Inc. merged with
Firstar Corporation on September 17, 1999.  As a result of that merger,
Mississippi Valley Advisors Inc. ("MVA"), formerly the investment adviser to
Mercantile, became an indirect wholly-owned subsidiary of Firstar Corporation.
On March 1, 2000, Firstar Investment Research & Management Company, LLC
("FIRMCO"), also a wholly-owned subsidiary of Firstar Corporation and investment
adviser to Firstar, acquired all of the assets and liabilities of MVA.  As a
result of this acquisition, FIRMCO became the investment adviser to Mercantile.

   FIRMCO is also the investment adviser for the Firstar Stellar Funds
("Stellar").  Prior to April 1, 2000, the Capital Management Division of Firstar
Bank, N.A. served as investment adviser to Stellar.  As part of an internal
restructuring of the investment advisory function within Firstar Corporation,
the investment management resources of the Capital Management Division of
Firstar Bank, N.A. have been consolidated with those of FIRMCO.  In addition, an
affiliate of FIRMCO, Firstar Bank, N.A., serves as the investment adviser to the
Firstar Select Funds ("Select").

   Because FIRMCO now manages Firstar, Mercantile and Stellar and its
affiliate manages Select, FIRMCO has decided to combine the assets of Firstar,
Mercantile, Stellar and Select into thirty-six separate Firstar investment
portfolios.

   At the upcoming Special Meeting, you will be asked to approve the
reorganization of your Mercantile Fund into a corresponding Firstar Fund (the
"Reorganization").  If shareholder approval is obtained, your Mercantile Fund
will be reorganized into the corresponding Firstar Fund in mid to late November
2000, when your shares in the Mercantile Fund will be exchanged for shares of
equal value of a corresponding Firstar Fund.

MERCANTILE'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE TO APPROVE
THE PROPOSED REORGANIZATION.

   In considering these matters, you should note:

 .  The Same or Similar Objectives and Policies

     Eleven of the Mercantile Funds (i.e. the Mercantile Treasury Money Market
Portfolio, Mercantile Money Market Portfolio, Mercantile Tax-Exempt Money Market
Portfolio, Mercantile Intermediate Corporate Bond Portfolio, Mercantile Short-
Intermediate Municipal Portfolio, Mercantile Balanced Portfolio, Mercantile
Equity Index Portfolio, Mercantile Growth & Income Equity Portfolio, Mercantile
Growth Equity Portfolio, Mercantile Small Cap Equity Portfolio and Mercantile
International Equity Portfolio) are proposed to be reorganized into existing
Firstar Funds that will have investment objectives and policies following the
Reorganization that are, in general, the same or similar to those of the
corresponding Mercantile Funds.

      Four of the Mercantile Funds (i.e. the Mercantile U.S. Government
Securities Portfolio, Mercantile Bond Index Portfolio, Mercantile Government &
Corporate Bond Portfolio and Mercantile National Municipal Bond Portfolio) are
proposed to be reorganized, together with another Mercantile Fund or a Stellar
fund ("Stellar Fund"), into existing Firstar Funds that have

                                      -2-
<PAGE>

not yet commenced operations. Each of these Firstar Funds will continue the
investment policies of one of the two Funds being reorganized into it. Each of
the Mercantile and/or Stellar Funds that are proposed to be reorganized into one
of these Firstar Funds have investment policies that are, in general, similar.

      Four of the Mercantile Funds (i.e. the Mercantile Conning Money Market
Portfolio, Mercantile Missouri Tax-Exempt Bond Portfolio, Mercantile Equity
Income Portfolio and Mercantile Small Cap Equity Index Portfolio) are proposed
to be reorganized into newly organized shell Firstar Funds that have been
specifically created for the purpose of the Reorganization.  Each of these newly
organized shell Firstar Funds will continue the investment policies of the
Mercantile Fund being reorganized into it.

 .   Same Value of Shares

      The Firstar Fund shares you receive in the Reorganization will have the
same total dollar value as the total dollar value of the Mercantile Fund shares
that you held immediately prior to the Reorganization.  The exchange of
Mercantile Fund shares for Firstar Fund shares will be tax-free under federal
tax laws, and no front-end or contingent deferred sales loads will be charged as
a result of the exchange.

 .   Reasons for the Reorganization

      The proposed Reorganization is expected to benefit Mercantile Fund
shareholders by, among other things:

(i)   offering a larger and more diverse group of mutual funds to all
shareholders;

(ii)  actually or potentially reducing overall expenses by the achievement of
economics of scale associated with a larger asset base;

(iii) offering an opportunity for better investment performance due to an
expanded equity research staff that can focus on the core products available.

(iv)  offering distribution channels that will have a better understanding of
the proprietary products offered by Firstar and will be better able to
communicate FIRMCO's investment style to existing and prospective shareholders,
thereby increasing assets in the complex; and

(v)   allowing FIRMCO to effect portfolio transactions on more favorable terms.

      To see how the Reorganization will affect your Mercantile Fund, please
carefully review the enclosed materials where you will find information on the
expenses, investment policies and services relating to the corresponding Firstar
Funds.

Statement/Prospectus and a Proxy Ballot are enclosed. If you own shares in more

                              Questions & Answers


For Shareholders of Mercantile Mutual Funds, Inc.:

The following questions and answers provide an overview of the proposal to
reorganize your portfolio of Mercantile Mutual Funds, Inc. ("Mercantile") into a
corresponding portfolio offered by Firstar Funds ("Firstar").  We also encourage
you to read the full text of the combined proxy statement/prospectus (the
"Proxy/Prospectus") that follows.

--------------------------------------------------------------------------------

Q:  What are Mercantile shareholders being asked to vote upon?

A:  Mercantile shareholders are being asked to consider and approve a proposal
to reorganize each of the portfolios offered by Mercantile (each, a "Mercantile
Fund") into a corresponding portfolio of Firstar (each, a "Firstar Fund").

Q.  Why has the reorganization of the Mercantile Funds into corresponding
Firstar Funds been recommended?

A:  The Board of Directors of Mercantile and the Board of Directors of Firstar
have each determined that the reorganization of each of the Mercantile Funds
into its respective corresponding Firstar Fund is in the best interests of the
respective shareholders of each such Fund.  Among the benefits for Mercantile
Fund shareholders considered by the Mercantile Board of Directors were:  access
to a larger and more diverse group of mutual funds; access to the expanded
equity research capabilities of Firstar Investment Research & Management
Company, LLC; the potential for individual Firstar Funds to achieve greater
portfolio diversification and engage in investment transactions on potentially
more advantageous terms; spreading relatively fixed costs, such as legal fees,
over a larger asset base; and the ability of Firstar to maintain existing
clients and attract new investors.

Q:  What is the anticipated timing of the reorganization?

A:  The meeting of shareholders to consider the proposal is scheduled to occur
on November 8, 2000.  If all necessary approvals are obtained, the proposed
reorganization will likely take place in mid to late November 2000.
<PAGE>

Q:  Who will receive the Proxy/Prospectus material?

A:  The Proxy/Prospectus has been mailed to all persons and entities that held
shares of record in a Mercantile Fund on September 15, 2000.  Please note that
in some cases record ownership of and/or voting authority over Mercantile Fund
shares may reside with a fiduciary or other agent.  In these cases, the
fiduciary or other agent may receive the combined Proxy/Prospectus.

Q:  How are the Mercantile Funds proposed to be reorganized?

A:  As you may know, Mercantile consists of nineteen separate mutual funds.  The
proposed agreement and plan of reorganization for these funds, approved by the
Mercantile Board of Directors, contemplates the reorganization of eleven of the
Mercantile Funds into eleven existing Firstar Funds having the same or similar
investment objectives and policies.  Four of the Mercantile Funds will be
reorganized, together with another Mercantile Fund or a fund of the Firstar
Stellar Funds ("Stellar Fund"), into existing Firstar Funds that have not yet
commenced operations.  Each of these Firstar Funds will continue the investment
policies of one of the two Funds that are being reorganized into it.  Each of
the Mercantile and/or Stellar Funds that will reorganize into the same Firstar
Fund have investment policies that are, in general, similar.  The remaining four
Mercantile Funds will be reorganized into four shell Firstar Funds that are
being created to continue the current operations of these Mercantile Funds.

    Under the proposed agreement and plan of reorganization, each Mercantile
Fund will be reorganized into the Firstar Fund listed directly opposite such
Mercantile Fund in the table below.  Those Mercantile Funds merging into Shell
Firstar Funds are printed in bold text.

*   Will continue the investment objectives and policies of a Stellar Fund with
    investment objectives and policies that are substantially similar to the
    investment objectives and policies of the corresponding Mercantile Fund.

**  Will continue the investment policies of the corresponding Mercantile Fund.

*** Will continue the investment policies of the Mercantile Government &
    Corporate Bond Portfolio.

+   It is expected that at the time of the Reorganization, the Firstar
    Intermediate Bond Market Fund will be renamed the Firstar Intermediate Bond
    Fund, the Firstar Growth Fund will be renamed the Firstar Large Cap Core
    Equity Fund, the Firstar Emerging Growth Fund will be renamed the Firstar
    Small Cap Core Equity Fund and the Firstar Core International Equity Fund
    will be renamed the Firstar International Growth Fund.

     Please refer to Tables III(A) and III(B) of the accompanying
Proxy/Prospectus for information regarding the specific classes of shares of the
Mercantile Funds and Firstar Funds involved in the Reorganization.

Q:  Which class of shares of the Firstar Funds will I receive in the
reorganization?

A:  Each Mercantile Fund except the Mercantile Conning Money Market Portfolio
and each Firstar Fund except the Firstar Conning Money Market Portfolio offers
multiple classes of shares to investors.  The various classes of Mercantile Fund
shares all represent interests in the same portfolio of securities owned by the
Mercantile Fund or Firstar Fund, but have different expenses and
characteristics, such as distribution and shareholder servicing arrangements,
that are intended to meet the needs of different types of investors.  In
general, eligibility to purchase a particular class of Mercantile Fund shares or
Firstar Fund shares turns on whether the investor is characterized as an
"institutional investor" or a "retail investor."

     As part of the reorganization, all shareholders of the Mercantile Conning
Money Market Portfolio will receive a single class of shares ("Shares") in the
corresponding Firstar Fund.  All shareholders of each of the Mercantile Treasury
Money Market Portfolio, Mercantile Money Market Portfolio and Mercantile Tax-
Exempt Money Market Portfolio will receive the following share classes of its
corresponding Firstar Fund:

Q:  What are the costs and federal tax implications to shareholders in
connection with the proposed reorganization?

A:  In general, the costs of the reorganization will not be borne by Mercantile
Fund shareholders.  No sales charge will be imposed on the shares of the Firstar
Funds issued to you in the reorganization, which means that the aggregate value
of the Firstar Fund shares issued to you will be equal to the aggregate value of
the Mercantile Fund shares that you own immediately prior to the reorganization.
In addition, the exchange of Mercantile Fund shares for Firstar Fund shares will
be tax-free under federal tax laws.  However, the sale of securities by a
Mercantile Fund, prior to the reorganization, whether in the ordinary course of
business or in anticipation of the reorganization, could increase the amount of
the taxable capital gains distribution made prior to the reorganization.  See
"The Reorganization - Federal Income Tax Considerations" for additional
information.

We need your proxy vote immediately.  You may think that your vote is not
important, but it is vital.  By law, the Special Meeting will have to be
adjourned without conducting any business if less than a majority of the shares
eligible to vote are represented.  In that event, Mercantile would continue to
solicit votes in an attempt to achieve a quorum.  Your vote could be critical in
allowing Mercantile to hold the Special Meeting as scheduled, so please return
your Proxy Ballot(s) immediately or vote on-line or by telephone.

Meeting of Shareholders (the "Special Meeting") to be held at the offices of
Mercantile's counsel, Drinker Biddle & Reath LLP, One Logan Square, 18th and

 .    To approve a proposed Agreement and Plan of Reorganization dated as of
     __________, 2000 (the "Reorganization Agreement"), by and between
     Mercantile and Firstar Funds, Inc. ("Firstar"), which provides for and
     contemplates (a) the transfer of substantially all of the assets and
     liabilities of each Mercantile Fund to a corresponding investment portfolio
     of Firstar (each a "Firstar Fund" and collectively, the "Firstar Funds") in
     exchange for shares of designated classes of the corresponding Firstar Fund
     of equal value; (b) the distribution of the shares of designated classes of
     the corresponding Firstar Fund to shareholders of each Mercantile Fund in
     liquidation of each of the Mercantile Funds; (c) the transfer of
     substantially all of the assets and liabilities of Mercantile; and (d) the
     dissolution of Mercantile under state law and the deregistration of
     Mercantile under the Investment Company Act of 1940, as amended (the "1940
     Act").

                                      -1-

     The Reorganization Agreement, the form of which is attached as Appendix I
to this Proxy/Prospectus, provides for the transfer of substantially all of the
assets and liabilities of each Mercantile Fund to a corresponding Firstar Fund
in exchange for Retail A Shares, Retail B Shares, Institutional Shares, Class Y
Shares or Shares, as applicable, of the corresponding Firstar Fund of equal
value. Mercantile and Firstar are both registered open-end management investment
companies (mutual funds). As a result of the reorganization, shareholders of the
Mercantile Funds will become shareholders of the Firstar Funds (the Mercantile
Funds and Firstar Funds are sometimes referred to as the "Funds").

     The transactions contemplated by the Reorganization Agreement are referred
to collectively as the "Reorganization."

     If the Reorganization Agreement is approved and the transactions
contemplated thereby are consummated, Mercantile will transfer all of its assets
and liabilities, deregister as a registered investment company and dissolve
under Maryland law.

     This Proxy/Prospectus sets forth concisely the information that a
Mercantile Fund shareholder should know before voting and investing, and should
be retained for future reference. It is both Mercantile's proxy statement for
the Special Meeting and a prospectus for the Firstar U.S. Treasury Money Market
Fund, Firstar Money Market Fund, Firstar Tax-Exempt Money Market Fund, Firstar
U.S. Government Securities Fund, Firstar Intermediate Bond Market Fund, Firstar
Aggregate Bond Fund, Firstar Tax-Exempt Intermediate Bond Fund, Firstar National
Municipal Bond Fund, Firstar Balanced Growth Fund, Firstar Equity Index Fund,
Firstar Growth & Income Fund, Firstar Growth Fund, Firstar Emerging Growth Fund
and Firstar Core International Equity Fund (the "Existing Firstar Funds"). It is
not a prospectus for the Firstar Conning Money Market Fund, Firstar Missouri
Tax-Exempt Bond Fund, Firstar Equity Income Fund and Firstar Small Cap Index
Fund (the "Shell Firstar Funds") because these funds were created to continue
the business of their corresponding Mercantile Funds. These four Shell Firstar
Funds will have substantially the same investment objectives, policies and
restrictions as its respective corresponding Mercantile Fund.

                                     SUMMARY

     The following is a summary of certain information relating to the proposed
Reorganization between Firstar and Mercantile.  More complete information is
contained elsewhere in this Proxy/Prospectus, the Prospectuses and Statements of
Additional Information of Firstar and Mercantile, and the Appendices attached
hereto.

     Proposed Reorganization.  The Reorganization Agreement provides for and
contemplates: (1) the transfer of substantially all of the assets and
liabilities of each Mercantile Fund to a corresponding investment portfolio
offered by Firstar (each, a "Corresponding Firstar Fund"), in exchange for
shares of the designated classes of such Corresponding Firstar Fund of equal
value (such shares of the designated classes of such Corresponding Firstar Fund,
the "Firstar Fund Shares"); (2) the distribution of the Firstar Fund Shares to
the shareholders of the Mercantile Funds in liquidation of each of the
Mercantile Funds; (3) the transfer of substantially all of the assets and
liabilities of Mercantile; and (4) the deregistration under the 1940 Act and the
dissolution under state law of Mercantile.  It is anticipated that the
Reorganization will take place in two stages, with fifteen of the Mercantile
Funds first transferring their respective assets and liabilities to fourteen
corresponding Existing Firstar Funds with the same or similar investment
objectives and policies in exchange for the Firstar Fund Shares issued by such
corresponding Existing Firstar Funds, and a week later, the remaining four
Mercantile Funds transferring their respective assets and liabilities to four
Shell Firstar Funds organized for the purpose of acquiring the assets and
liabilities, and then continuing the business, of such Mercantile Fund, in
exchange for the Firstar Fund Shares issued by such corresponding Shell Firstar
Funds.  The liquidation of each Mercantile Fund, and the distribution of the
Firstar Fund Shares to the respective shareholders of such Mercantile Fund,
shall occur immediately after the receipt by such Mercantile Fund of all of the
Firstar Fund Shares to be received by such Mercantile Fund in the
Reorganization.  The Reorganization is subject to a number of conditions,
including approval by the shareholders of each Mercantile Fund.

     As a result of the proposed Reorganization, each Mercantile Fund
shareholder will become a shareholder of its Corresponding Firstar Fund and will
hold, immediately after the Reorganization, Firstar Fund Shares in such
Corresponding Firstar Fund having a total dollar value equal to the total dollar
value of the shares such shareholder held in the Mercantile Fund immediately
prior to the effectiveness of the Reorganization.  The exchange of shares in the
Reorganization will be tax-free under federal tax laws and shareholders of the
Firstar Funds and the Mercantile Funds will not pay any sales charge as a result
of the exchange of the shares in the Reorganization.

     Shareholders of the Mercantile Conning Money Market Portfolio will receive
Shares of the Corresponding Firstar Fund.  Shareholders of each of the
Mercantile Treasury Money Market Portfolio, Mercantile Money Market Portfolio
and Mercantile Tax-Exempt Money Market Portfolio will receive the following
share classes of its Corresponding Firstar Fund:

  The Reorganization is expected to occur in mid to late November, 2000 or such
later date as may be determined pursuant to the Reorganization Agreement.  For
more information about the Reorganization and the Reorganization Agreement, see
the Section below entitled "The Reorganization - Description of the
Reorganization Agreement."

     At the same time that the Mercantile Funds are reorganized into the Firstar
Funds, it is expected that the investment portfolios of the Firstar Stellar
Funds ("Stellar") and the Firstar Select Funds ("Select") will be reorganized
into certain investment portfolios offered by Firstar, including, in the case of
the Stellar reorganization, certain of the Corresponding Firstar Funds.  In
particular, it is expected that (1) the Stellar Treasury Fund, together with the
Mercantile Treasury Money Market Portfolio, will be reorganized into the Firstar
U.S. Treasury Money Market Fund, (2) the Stellar Tax-Free Money Market Fund,
together with the Mercantile Tax-Exempt Money Market Portfolio, will be
reorganized into the Firstar Tax-Exempt Money Market Fund, (3) the

                                      -10-

Stellar U.S. Government Income Fund, together with the Mercantile U.S.
Government Securities Portfolio, will be reorganized into the Firstar U.S.
Government Securities Fund, and (4) the Stellar Insured Tax-Free Bond Fund,
together with the Mercantile National Municipal Bond Portfolio, will be
reorganized into the Firstar National Municipal Bond Fund. If the Reorganization
Agreement is approved by Mercantile shareholders at the Special Meeting, it is
expected that the Reorganization will be completed whether or not the Stellar
reorganization and Select reorganization are completed.

     The investment objective, policies and restrictions of (i) the
Mercantile Conning Money Market Portfolio, (ii) the Mercantile Missouri Tax-
Exempt Bond Portfolio, (iii) the Mercantile Equity Income Portfolio and (iv) the
Mercantile Small Cap Equity Index Portfolio (collectively, the "Continuing
Mercantile Funds") are substantially the same as those of their Corresponding
Firstar Funds, because their Firstar Shell Funds have each been organized solely
in connection with this Reorganization to acquire the assets and liabilities,
and continue the business, of its corresponding Continuing Mercantile Fund.

     The investment objectives, policies and restrictions of each of the other
Mercantile Funds (collectively, the "Reorganizing Mercantile Funds") are, in
general, substantially the same as or similar to those of its Corresponding
Firstar Fund. However, there are certain differences between the investment
policies and restrictions of certain of the Reorganizing Mercantile Funds and
their Corresponding Firstar Funds. For additional information, see "Comparison
of Mercantile Funds and Firstar Funds - Investment Objectives and Policies" and
Appendix III.

     It is expected that at the time of the Reorganization, the Firstar U.S.
Treasury Money Market Fund, the Firstar Emerging Growth Fund and the Firstar
Core International Equity Fund will adopt investment objectives, policies and
restrictions that are substantially the same as the investment objectives,
policies and restrictions of the Stellar Treasury Fund, the Mercantile Small Cap
Equity Portfolio and the Mercantile International Equity Portfolio,
respectively. For a complete description of the investment objective, policies
and restrictions of the Stellar Treasury Fund, see Exhibit A to Appendix III of
this Proxy/Prospectus.

     FIRMCO currently serves as adviser to each of the Mercantile Funds and
currently serves or will serve as the investment adviser to each of the Firstar
Funds. Conning Asset Management Company ("Conning") currently serves as sub-
adviser to the Mercantile Conning Money Market Portfolio and will serve as sub-
adviser to the Firstar Conning Money Market Fund. Clay Finlay, Inc. ("Clay
Finlay") currently serves as sub-adviser to the Mercantile International Equity
Portfolio. It is expected that at the time of the Reorganization, Clay Finlay
also will serve as sub-adviser to the Firstar Core International Equity Fund.
Firstar intends to call a special meeting of shareholders of the Firstar Core
International Equity Fund to approve Clay Finlay as sub-adviser. If this
engagement is not approved by shareholders of the Firstar Core International
Equity Fund,

then the Fund's existing sub-advisory arrangements with The Glenmede Trust
Company described in the enclosed prospectuses of the Firstar Funds will remain
in effect.

______________
+ The differentials listed in this column are determined in the same manner as
the example listed below:

       The Firstar U.S. Treasury Money Market Fund's contractual advisory fee
       rate is 0.44% and the Mercantile Treasury Money Market Portfolio's
       contractual advisory fee rate is 0.40%. Therefore, the contractual
       advisory fee rate for the Firstar U.S. Treasury Fund Portfolio is 0.04%
       higher than the contractual advisory rate for the Mercantile Treasury
       Money Market Portfolio.

* The contractual advisory fee rate will be .05% higher than the contractual
advisory fee rate of the Mercantile Government & Corporate Bond Portfolio and
 .20% higher than the contractual advisory fee rate for the Mercantile Bond Index
Portfolio.

       For more information on advisory fee rates, see "Comparison of Mercantile
Funds and Firstar Funds - Investment Advisory Services - Table V."

                                      -14-
<PAGE>

     Advisory fees, however, are only one type of fee and expense paid by mutual
funds. As noted previously in "Fee Tables - Tables I(A) and I(B)," (i) twelve of
the eighteen Mercantile Funds that offer Investor A Shares, three of the eleven
Mercantile Funds that offer Investor B Shares, eleven of the fourteen Mercantile
Funds that offer Institutional Shares, seven of the eighteen Mercantile Funds
that offer Trust Shares and none of the Mercantile Funds that offer Trust II
Shares will have total operating expense ratios (after fee waivers) which are
lower after the Reorganization; (ii) two of the eighteen Mercantile Funds that
offer Investor A Shares, three of the eleven Mercantile Funds that offer
Investor B Shares, one of the fourteen Mercantile Funds that offer Institutional
Shares, five of the eighteen Mercantile Funds that offer Trust Shares and none
of the Mercantile Funds that offer Trust II Shares will have the same total
operating expense ratios (after fee waivers) after the Reorganization; and (iii)
four of the eighteen Mercantile Funds that offer Investor A Shares, five of the
eleven Mercantile Funds that offer Investor B Shares, two of the fourteen
Mercantile Funds that offer Institutional Shares, six of the eighteen Mercantile
Funds that offer Trust Shares and all three of the Mercantile Funds that offer
Trust II Shares will have total operating expense ratios (after fee waivers)
which are higher after the Reorganization. For a more detailed summary of fees
and expenses, see Appendix II.

     Firstar Mutual Fund Services, LLC ("FMFS") serves as administrator of the
Firstar Funds.  FMFS also serves as co-administrator of the Mercantile Funds
along with BISYS Fund Services Ohio, Inc.  FMFS serves as transfer agent to both
the Mercantile Funds and the Firstar Funds and Firstar Bank, N.A. serves as
custodian for both the Mercantile Funds and the Firstar Funds.  The Mercantile
Funds and Firstar Funds have different distributors.  For a detailed description
of the management of the Firstar Funds, including FIRMCO, Conning and Clay
Finlay and the other service providers to the Firstar Funds, see "Comparison of
Mercantile Funds and Firstar Funds - Investment Advisory Services," "Comparison
of Mercantile Funds and Firstar Funds - Other Service Provides for the
Mercantile Funds and the Firstar Funds" and the Firstar Fund prospectus which
accompanies this Proxy/Prospectus.

     The purchase, redemption, exchange, dividend and other policies and
procedures of the Mercantile Funds and their Corresponding Firstar Funds are
generally similar.  There are, however, some differences, such as with respect
to the categories of shareholders eligible for sales charge waivers.  For more
information, see "Comparison of Mercantile Funds and Firstar Funds - Shareholder
Transactions and Policies," "Comparison of Mercantile Funds and Firstar Funds -
Share Structure" and Appendix IV to this Proxy/Prospectus.  Please note that no
contingent deferred sales loads will be imposed on any Mercantile Fund shares as
a result of the Reorganization.  In addition, no front-end sales load will be
imposed on any Firstar Fund Shares issued in the Reorganization.

     Federal Income Tax Consequences. The exchange of shares in the
Reorganization is not expected to result in the recognition, for federal income
tax purposes, of gain or loss by the Mercantile Funds, the Firstar Funds or
their respective shareholders. The sale of securities by the Mercantile Funds
prior to the Reorganization, whether in the ordinary course of business or in
anticipation of the Reorganization, could increase the amount of the taxable
capital gains distributions made prior to the Reorganization.  See "The
Reorganization - Federal Income Tax Considerations" for additional information.

                                      -15-

     Mercantile and Firstar Board Consideration.  During its deliberations,
Mercantile's Board of Directors (with the advice and assistance of its counsel)
reviewed, among other things:  (1) the potential effect of the Reorganization on
the shareholders of the Mercantile Funds; (2) the capabilities, practices and
resources of FIRMCO and the Firstar Funds' other services providers; (3) the
investment advisory and other fees paid by the Firstar Funds, and the historical
and projected expense ratios of the Firstar Funds as compared with those of the
Mercantile Funds and industry peer groups; (4) the investment objectives,
policies and limitations of the Firstar Funds and their relative compatibility
with those of the Mercantile Funds; (5) the historical investment performance
records of the Mercantile Funds and the Firstar Funds, relative to each other
and to peer groups or indices; (6) the shareholder services offered by Firstar;
(7) the terms and conditions of the Reorganization Agreement; (8) the
anticipated tax consequences of the Reorganization for the respective Mercantile
Funds and their shareholders; and (9) the number of investment portfolio options
that would be available to shareholders after the Reorganization.  The
Mercantile Board also considered FIRMCO's belief that the Reorganization would
eliminate certain duplicative shareholder costs and market overlap, facilitate
consolidation of FIRMCO's managerial resources and enhance generally operational
efficiencies and focus with respect to the mutual funds advised by FIRMCO.  For
additional information, see "The Reorganization - Mercantile Board
Consideration."

     Based upon their evaluation of the information presented to them, and in
light of their fiduciary duties under federal and state law, the Board of
Directors of Mercantile, including all of the non-interested members of the
Board, determined that participation in the Reorganization, as contemplated by
the Reorganization Agreement, was in the best interests of the shareholders of
each Mercantile Fund and that the interests of the existing shareholders of each
Mercantile Fund would not be diluted as a result of the Reorganization.

     The Mercantile Board of Directors unanimously recommends that shareholders
of each Mercantile Fund approve the Reorganization Agreement.

     After considering the relevant factors, the Firstar Board of Directors
similarly found that participation in the Reorganization was in the best
interests of the Firstar Funds and that the interests of the shareholders of the
Firstar Funds would not be diluted as a result of the Reorganization.

     Principal Risk Factors. Because each of the Firstar Shell Funds is being
created to acquire substantially all of the assets and liabilities, and then
continue the business, of its corresponding Continuing Mercantile Fund, an
investment in a Firstar Shell Fund involves risks that are substantially the
same as those of investing in its corresponding Continuing Mercantile Fund. The
investment objectives, policies and restrictions of each Existing Firstar Fund
are, in general, the same as or similar to those of its corresponding Mercantile
Fund. Accordingly, an investment in an Existing Firstar Fund involves risks that
are similar to those of investing in its corresponding Reorganizing Mercantile
Fund. The principal risks applicable to the Mercantile Funds and the Firstar
Funds are described in the table below. Additional information regarding these
risks and other risks to which the Funds are subject are described in the
respective prospectuses and statements of additional information for the Funds.
The definitions of the terms

                                      -16-

used in the tables immediately follow the tables. The Mercantile Funds and
Firstar Funds are classified in the following groups:

     "Mercantile Money Market Funds" means, collectively, the Mercantile
Treasury Money Market Portfolio, Mercantile Money Market Portfolio, Mercantile
Tax-Exempt Money Market Portfolio and Mercantile Conning Money Market Portfolio.

     "Firstar Money Market Funds" means, collectively, the Corresponding Firstar

investment performance of a benchmark index,
before fund expenses.  The Fund may fail to            Mercantile Bond Index, Equity Index and

Municipal Government Risk - The ability of a           Firstar Tax-Exempt Money Market and

payments can be affected by many factors,
including economic conditions, the flow of             Mercantile Tax-Exempt Money Market

held by the Fund may underperform other
types of stocks, and they may not increase
or may decline in value.  Foreign
investments may be riskier than U.S.
investments because of factors such as
foreign government restrictions, changes in
currency exchange rates, incomplete

securities, and political or economic
instability.  Foreign stocks may be more
volatile and less liquid than U.S. stocks.

------------------------------------------------------------------------------------------------
Non-Diversification Risk - The Fund is                 Firstar Missouri Tax-Exempt Bond Fund
non-diversified, which means that it can
invest a large percentage of its assets in a           Mercantile Tax-Exempt Money Market and
small number of issues.  As a result, a                Missouri Tax-Exempt Bond Portfolios

are issued by a state or local government or
authority to acquire land and a wide variety

Investment in Missouri Risk - Because the              Firstar Missouri Tax-Exempt Bond Fund

especially susceptible to economic,                    Portfolio
political and regulatory events that affect
Missouri.  Missouri's economy is largely
comprised of services, manufacturing
(primarily defense, transportation and other
durable goods), wholesale and retail trade,
and state and local government.  The
exposure to these industries leaves Missouri
vulnerable to an economic slowdown
associated with the business cycles of such
industries.  Because defense-related
business plays an important role in
Missouri's economy, declining defense
appropriations and federal downsizing also
may continue to have an adverse impact on
the State.  From time to time, Missouri and
its political subdivisions have encountered
financial difficulties.

Large Cap Indexing Risk - Your investment              Firstar Equity Index Fund
follows the large-cap portion of the U.S.
stock market, as measured by the S&P 500               Mercantile Equity Index Portfolio
Index, during upturns as well as downturns.
Because of its indexing strategy, the Fund
cannot take steps to reduce market
volatility or to lessen the effects of a
declining market.

Whenever large-cap stocks perform less than
mid- or small-cap stocks, the Fund may
under-perform funds that have exposure to
those segments.

Further, the Fund will not necessarily
dispose of a security in response to adverse
events affecting the issuer of a security

to pay dividends).

------------------------------------------------------------------------------------------------
Emerging Market Risk - The risks associated            Firstar Core International Equity Fund
with foreign investments are heightened when
investing in emerging markets. The                     Mercantile International Equity Portfolio
governments and economies of emerging market
countries feature greater instability than
those of more developed countries. Such

Currency Risk - Currency risk is the                   Firstar Core International Equity Fund
potential for price fluctuations in the

the Fund holds because of changing currency

Focus Risk - Because of the smaller number of          Firstar Intermediate Bond Market Fund

index, material events affecting the Fund's
portfolio (for example, an issuer's decline
in credit quality) may influence the
performance of the Fund to a greater degree

------------------------------------------------------------------------------------------------
Fixed Income Management Risk - While the               Firstar Intermediate Bond Market Fund
adviser believes purchasing securities which
are not in the Fund's benchmark index or not
consistent with the "mix" of the index
provides the opportunity to achieve an
enhanced gross return compared to the index,
the investment adviser may err in its
choices of securities or portfolio mixes.
Further, the Adviser calculates the Fund's
duration and average maturity based on
certain estimates relating to the duration
and maturity of the securities held by the
Fund.  The estimates used may not always be
accurate, so the investment adviser's
calculations may be incorrect.  Such errors
could result in a negative return and a loss
to you.

------------------------------------------------------------------------------------------------
Tax Risk - The Fund may be more adversely              Firstar Tax-Exempt Intermediate Bond

policies than other funds.

------------------------------------------------------------------------------------------------
Futures Risk - The Fund invests in futures             Firstar Equity Index Fund

                              THE REORGANIZATION

       Reasons for the Reorganization. Significant features of the
Reorganization are summarized below. This summary is qualified in its entirety
by reference to the Reorganization Agreement, the form of which is attached as
Appendix I.

       The proposed Reorganization is expected to benefit Mercantile Fund
shareholders by, among other things:

(i)    Offering a larger and more diverse group of mutual funds to all
shareholders;

(ii)   Actually or potentially reducing overall expenses by the achievement of
economies of scale associated with a larger asset base;

(iii)  Offering an opportunity for better investment performance due to an
expanded equity research staff that can focus on the core products available;

(iv)   Offering distribution channels that will have a better understanding of
the proprietary products offered by Firstar and will be better able to
communicate FIRMCO's investment style to existing and prospective shareholders,
thereby potentially increasing assets in the complex; and

(v)    Allowing FIRMCO to effect portfolio transactions on more favorable terms.

                                      -26-

     Description of the Reorganization Agreement. There are nineteen separate
Mercantile Funds. The Reorganization Agreement provides that substantially all
of the assets and liabilities of each of the fifteen Reorganizing Mercantile
Funds identified in column 1 on Table III(A) below will be transferred to, and
acquired by, one of the fourteen Existing Firstar Funds identified in column 2
on Table III(A) below, in exchange for full and fractional shares issued by such
Existing Firstar Fund. The Reorganization Agreement further provides that
substantially all of the assets and liabilities of each of the Continuing
Mercantile Funds identified in column 1 on Table III(B) below will be
transferred to, and acquired by, one of the newly-organized Shell Firstar Funds
identified in column 2 on Table III(B) below, in exchange for full and
fractional shares issued by such Shell Firstar Fund. In the tables, opposite the
name of each Mercantile Fund is the name of the Corresponding Firstar Fund to
which such Mercantile Fund will transfer substantially all of its assets and
liabilities and that will issue Firstar Fund Shares of designated classes to
such Mercantile Fund in consideration of such transfer. The Firstar Fund Shares
issued by each Firstar Fund to its corresponding Mercantile Fund will have the
same aggregate dollar value as the aggregate dollar value of the shares of such
Mercantile Fund immediately prior to the effective time of the Reorganization
with respect to such Fund.

     Immediately after the effective time of the Reorganization, each Mercantile
Fund will distribute to its shareholders the Firstar Fund Shares received in the
Reorganization in liquidation of the Mercantile Fund.  Each shareholder of
record of a particular Mercantile Fund at the effective time of the
Reorganization will receive shares of the designated class of its Corresponding
Firstar Fund with the same aggregate dollar value of the shares such shareholder

                                      -32-
<PAGE>

held in such Mercantile Fund prior to the effective time of the Reorganization,
and will receive any unpaid dividends or distributions declared before the
effective time of the Reorganization with respect to a Mercantile Fund.

     Firstar will establish an account for each former shareholder of the
Mercantile Funds that will reflect the number and class of Firstar Fund Shares
distributed to that shareholder.  The Firstar Fund Shares issued in the
Reorganization will be in uncertificated form.

     Please note that a vote for or against the Reorganization Agreement
includes a vote for or against the reorganization of Mercantile into Firstar. If
the Reorganization Agreement is approved and the transactions contemplated
thereby are consummated, Mercantile will transfer substantially all of its
assets and liabilities as of the effective time of the Reorganization, all
outstanding shares of the Mercantile Funds will be redeemed and cancelled in
exchange for Firstar Fund Shares of the Firstar Funds, and Mercantile will wind
up its affairs and apply to be deregistered as an investment company under the
1940 Act and thereafter dissolve under Maryland law.

     The Reorganization is subject to a number of conditions, including approval
of the Reorganization Agreement and the related matters described in this
Proxy/Prospectus by a majority of the outstanding shares of each Mercantile
Fund; approval of the Reorganization by a majority of all of the shares of all
of the Mercantile Funds voting in the aggregate; the receipt of certain legal
opinions described in the Reorganization Agreement (which include an opinion of
Firstar's counsel addressed to Mercantile indicating that the Firstar Fund
Shares issued in the Reorganization will be validly issued, fully paid and non-
assessable); the receipt of certain certificates from the parties concerning the
continuing accuracy of the representations and warranties in the Reorganization
Agreement; the receipt of any necessary exemptive relief requested from the SEC
or its staff with respect to Section 17(a) of the 1940 Act; and the parties'
performance in all material respects of their respective covenants and
undertakings as described in the Reorganization Agreement.

     It is possible that a majority of a Mercantile Fund's shareholders may
approve the Reorganization Agreement while a majority of all shareholders of all
Mercantile Funds does not approve the reorganization of Mercantile. In such a
case, the Mercantile Board of Directors will contemplate what further action is
appropriate.

     The Reorganization Agreement also provides that FIRMCO or an affiliate has
agreed to pay all expenses associated with the Reorganization.  The
Reorganization Agreement also provides, among other things, that the
Reorganization may be terminated at any time upon the mutual consent of both
Mercantile and Firstar, or by either Firstar or Mercantile under certain
conditions; and that officers of Firstar and of Mercantile may amend the
Reorganization Agreement as authorized by their respective Boards of Directors.

     As previously noted, the Stellar reorganization and the Select
reorganization are expected to occur at the same time as the Reorganization. In
connection with the Stellar reorganization, certain of the Stellar investment
portfolios will be reorganized into the same Firstar Fund as certain of the
Mercantile Funds. In particular, (1) the Stellar Treasury Fund, together with
the Mercantile Treasury Money Market Portfolio, will be reorganized into the
Firstar U.S. Treasury Money Market Fund, (2) the Stellar Tax-Free Money Market
Fund, together with the Mercantile Tax-Exempt Money Market Portfolio, will be
reorganized into the Firstar Tax-Exempt Money Market Fund, (3) the Stellar U.S.
Government Income Fund, together with the Mercantile U.S. Government Securities
Portfolio, will be reorganized into the Firstar U.S. Government Securities Fund,
and (4) the Stellar Insured Tax-Free Bond Fund, together with the Mercantile
National Municipal Bond Portfolio, will be reorganized into the Firstar National
Municipal Bond Fund. If the Reorganization Agreement is approved by Mercantile
shareholders at the Special Meeting, it is expected that the Reorganization will
be completed whether or not the Stellar reorganization and Select reorganization
are completed.

     Mercantile Board Consideration. At a meeting held on April 18, 2000, the
Board of Directors of Mercantile was advised that FIRMCO was considering
recommending a consolidation of Mercantile with Firstar.  The Mercantile Board
then met again on June 6, 2000 and July 11, 2000 to consider the Reorganization
proposal offered by management of Firstar, FIRMCO and its affiliates.  In
preparation for the June 6, 2000 meeting, each of the Directors of Mercantile
was provided with detailed information about the Reorganization, Firstar and
FIRMCO.  These materials summarized the principal terms and conditions of the
Reorganization, including the intention that the Reorganization be consummated
on a tax-free basis for each Mercantile Fund and its respective shareholders.
In addition, the Mercantile Directors received comparative information about the
Mercantile Funds and the Corresponding Firstar Funds, including information
concerning, but not limited to, the following matters:  (1) investment
objectives and policies; (2) advisory, distribution and servicing arrangements;
(3) fund expenses (with and without giving effect to current expense
limitations), including pro forma expenses, relative to peer groups or
comparable indices; and (4) performance, including performance relative to peer
groups for the Firstar Funds.  The Mercantile Board also was provided with
information about FIRMCO and its investment advisory organization, including the
individuals or teams of individuals with responsibility for managing each
Firstar Fund.

     The Reorganization was unanimously approved by the Mercantile Board of
Directors on June 6, 2000 subject to the Board's receipt from FIRMCO of
additional information on certain aspects of the Reorganization.  This
additional information was received and considered by the Mercantile Board and
on July 11, 2000, the Board of Directors of Mercantile unanimously ratified the
actions it had taken on June 6, 2000 approving the Reorganization.

                                      -34-
<PAGE>

     During its deliberations, Mercantile's Board of Directors (with the advice
and assistance of its counsel) reviewed, among other things:  (1) the potential
effect of the Reorganization on the shareholders of the Mercantile Funds; (2)
the capabilities, practices and resources of FIRMCO and the Firstar Funds' other
service providers; (3) the investment advisory and other fees paid by the
Firstar Funds, and the historical and projected expense ratios of the Firstar
Funds as compared with those of the Mercantile Funds and industry peer groups or
comparable indices; (4) the investment objectives, policies and limitations of
the Firstar Funds and their relative compatibility with those of the Mercantile
Funds; (5) the historical investment performance records of the Mercantile Funds
and the Firstar Funds relative to each other and, with respect to the Firstar
Funds, to peer groups; (6) the shareholder services offered by Firstar; (7) the
terms and conditions of the Reorganization Agreement; (8) the anticipated tax
consequences of the Reorganization for the respective Mercantile Funds and their
shareholders; and (9) the number of investment portfolio options that would be
available to shareholders after the Reorganization.  The Mercantile Board also
considered FIRMCO's belief that the Reorganization would eliminate certain
duplicative shareholder costs and market overlap, facilitate consolidation of
FIRMCO's managerial resources and enhance generally operational efficiencies and
focus with respect to the mutual funds advised by FIRMCO.

     The Mercantile Directors also noted that the per share annualized total
operating expense ratios for certain of the classes of certain of the Firstar
Funds after the Reorganization, taking into account voluntary fee waivers, would
be higher than those of the corresponding Mercantile Funds before the
Reorganization.  See "Table I-B - Total Expense Information" and Appendix II for
more information.  The Mercantile Directors also noted that FIRMCO or an
affiliate would assume all customary expenses associated with the Reorganization
and that FIRMCO would commit to waive fees and reimburse expenses as needed to
ensure that until October 31, 2001 the Firstar Funds' total operating expense
ratios would not exceed the pro forma after waiver expenses shown in Table I-B.

     After consideration of the foregoing and other factors, the Mercantile
Directors unanimously determined that the Reorganization was in the best
interest of the shareholders of each Mercantile Fund, and that the interests of
the existing shareholders of each Mercantile Fund would not be diluted as a
result of such Reorganization.

     Capitalization. The following table sets forth, as of April 30, 2000 (the
end of Firstar's semi-annual period): (1) the capitalization of each of the
Mercantile Funds; (2) the capitalization of each of their Corresponding Firstar
Funds; and (3) the pro forma capitalization of each of the Corresponding Firstar
Funds as adjusted to give effect to the Reorganization. With respect to the
Mercantile Treasury Money Market Portfolio, Mercantile Tax-Exempt Money Market
Portfolio, Mercantile U.S. Government Securities Portfolio and Mercantile
National Municipal Bond Portfolio, the table also sets forth the capitalization
of the Stellar portfolio which will simultaneously be reorganized into the
Corresponding Firstar Fund of such Mercantile Fund and the pro forma
capitalization of such Corresponding Firstar Fund as adjusted to give effect to
both the Reorganization and the Stellar reorganization. With respect to the
Mercantile Bond Index Portfolio and the Mercantile Government & Corporate Bond
Portfolio, the table sets forth the capitalization of each such Mercantile Fund,
the pro forma capitalization of the Corresponding Firstar Fund as adjusted to
give effect to the reorganization of the Mercantile Bond Index

                                      -35-
<PAGE>

Portfolio only, the pro forma capitalization of the Corresponding Firstar Fund
as adjusted to give effect to the reorganization of the Mercantile Government &
Corporate Bond Portfolio only, and the pro forma capitalization of the
Corresponding Firstar Fund as adjusted to give effect to the reorganization of
both the Mercantile Bond Index Portfolio and the Mercantile Government &
Corporate Bond Portfolio.

     The capitalization of each Fund is likely to be different at the effective
time of the Reorganization as a result of daily share purchase and redemption
activity in the Funds as well as the effects of the other ongoing operations of
the respective Funds prior to the closing of the Reorganization.

     The Firstar Conning Money Market Fund, Firstar Missouri Tax-Exempt Bond
Fund, Firstar Equity Income Fund and Firstar Small Cap Index Fund have not yet
commenced operations but will do so at the time the Reorganization occurs.

1.  The table below reflects the capitalization as of April 30, 2000 and pro
forma capitalization for the combination of the Mercantile Treasury Money Market
Portfolio and Stellar Treasury Fund with the Firstar U.S. Treasury Money Market
Fund.  The table provides pro forma capitalization information for two different
scenarios: (a) the combination of the Mercantile Treasury Money Market Portfolio
with the Firstar U.S. Treasury Money Market Fund (Pro forma Combined Fund = Fund
A + Fund C) and (b) the combination of the Mercantile Treasury Money Market
Portfolio and the Stellar Treasury Fund with the Firstar Treasury Money Market
Fund (Pro forma Combined Fund = Fund A + Fund B + Fund C).

     Federal Income Tax Considerations. Each Firstar Fund and each Mercantile
Fund intends to qualify as of the effective time of the Reorganization as a
separate "regulated investment company" under the Internal Revenue Code of 1986,
as amended (the "Code"). Accordingly, each Mercantile Fund and each
Corresponding Firstar Fund has been, and expects to continue to be, relieved of
federal income tax liability.

     Consummation of the Reorganization with respect to each Mercantile Fund and
its Corresponding Firstar Fund is subject to the condition that Mercantile and
Firstar receive an opinion from Drinker Biddle & Reath LLP substantially to the
effect that, for federal income tax purposes: (i) the transfer of substantially
all of the assets and liabilities of a Mercantile Fund to its Corresponding
Firstar Fund in exchange for the Firstar Fund Shares issued by such
Corresponding Firstar Fund, and the distribution of those Firstar Fund Shares to
shareholders of the Mercantile Fund, will consist of nineteen "reorganizations"
within the meaning of Section 368(a) of the Code, and each Mercantile Fund and
its Corresponding Firstar Fund will each be a "party to a reorganization" within
the meaning of Section 368(b) of the Code in respect of the Reorganization; (ii)
no gain or loss will be recognized by any Mercantile Fund upon the transfer of
its assets and liabilities to its Corresponding Firstar Fund solely in exchange
for Firstar Fund Shares of the Corresponding Firstar Fund; (iii) no gain or loss
will be recognized by each Firstar Fund upon the receipt of the assets and
assumption of the liabilities of its Corresponding Mercantile Fund solely in
exchange for the Firstar Fund Shares; (iv) the basis of each Mercantile Fund's
assets received by the Corresponding Firstar Fund pursuant to the Reorganization
will be the same as the basis of those assets in the hands of such Mercantile
Fund immediately prior to the Reorganization; (v) the holding period of each
Mercantile Fund's assets in the hands of its Corresponding Firstar Fund will
include the period for which such assets have been held by such Mercantile Fund;
(vi) no gain or loss will be recognized by any Mercantile Fund on the
distribution to its shareholders of the Firstar Fund Shares of its Corresponding
Firstar Fund; (vii) no gain or loss will be recognized by the shareholders of
any Mercantile Fund upon their receipt of the Firstar Fund Shares in exchange
for such shareholders' shares of the Mercantile Fund; (viii) the basis of the
Firstar Fund Shares received by the shareholders of each Mercantile Fund will be
the same as the basis of the Mercantile Fund shares surrendered by such
shareholders pursuant to the Reorganization; (ix) the holding period for the
Firstar Fund Shares received by each Mercantile Fund shareholder will include
the period during which such shareholder held the Mercantile Fund shares
surrendered in exchange therefor, provided that such Mercantile Fund shares are
held as a capital asset in the hands of such Mercantile Fund shareholder on the
date of the exchange; and (x) each Firstar Fund will succeed to and take into
account the tax attributes described in Section 381(c) of the Code of the
Mercantile Fund as of the effective time of the Reorganization with respect to
the Mercantile Fund, subject to the conditions and limitations specified in the
Code.  Shareholders of the Mercantile Funds should note, however, that the sale
of securities by the Mercantile Funds prior to the effective time of the
Reorganization, whether in the ordinary course of business or in anticipation of
the Reorganization, could increase the amount of the taxable capital gains
distributions made prior to the Reorganization.

     Firstar and Mercantile have not sought, and will not seek, a private ruling
from the Internal Revenue Service ("IRS") with respect to the federal income tax
consequences of the Reorganization.  The opinion of Drinker Biddle & Reath LLP
with respect to the federal income

                                      -57-
<PAGE>

tax consequences of the Reorganization is not binding on the IRS and does not
preclude the IRS from adopting a contrary position. Shareholders should consult
their own advisers concerning the potential tax consequences of the
Reorganization to them, including any applicable foreign, state or local income
tax consequences.


               COMPARISON OF MERCANTILE FUNDS AND FIRSTAR FUNDS


     Investment Objectives and Policies.  The investment objectives, policies
and restrictions of each Mercantile Fund are, in general, similar to those of
its Corresponding Firstar Fund.  They are summarized in Appendix III.  Moreover,
(i) the investment objective, policies and restrictions of each of the
Mercantile U.S. Government Securities Portfolio and Mercantile National
Municipal Bond Portfolio are, in each case, substantially the same as those of
its respective Corresponding Existing Firstar Fund and the investment policies
and restrictions of the Mercantile Government & Corporate Bond Portfolio are
substantially the same as, and the Portfolio's investment objective is similar
to, those of its Corresponding Existing Firstar Fund, and (ii) the investment
objective, policies and restrictions of each of the Mercantile Conning Money
Market Portfolio, Mercantile Missouri Tax-Exempt Bond Portfolio, Mercantile
Equity Income Portfolio and Mercantile Small Cap Equity Index Portfolio are, in
each case, substantially the same as those of its respective Corresponding Shell
Firstar Fund.  Each Shell Firstar Fund is being created to acquire the assets
and liabilities, and continue the business, of its respective corresponding
Continuing Mercantile Fund.  With the exception of the Mercantile U.S.
Government Securities Portfolio, Mercantile Government & Corporate Bond
Portfolio and Mercantile National Municipal Bond Portfolio described above,
there are, however, certain differences in the types of securities in which each
of the Reorganizing Mercantile Funds may invest and the types of securities in
which its Corresponding Firstar Fund may invest, as well as differences in
certain investment policies of such Funds.  A discussion of some of the more
significant differences between the Funds follows.

     Reorganizing Money Market Funds.  The Mercantile Money Market Funds and the
     -------------------------------
Firstar Money Market Funds are all subject to the general restrictions and
limitations of Rule 2a-7 under the 1940 Act.  However, there are differences
between the investment policies and restrictions of the Mercantile Money Market
Funds and their corresponding Firstar Funds.  For example, the Mercantile
Treasury Money Market Portfolio invests in obligations issued by the U.S.
Treasury and certain U.S. Government agencies and instrumentalities that provide
income that is generally not subject to state income tax, while the Firstar U.S.
Treasury Money Market Fund invests in obligations issued or guaranteed as to
principal and interest by the U.S. Treasury.  Similarly, the Firstar Treasury
Money Market Portfolio may enter into repurchase agreements whereas the
Mercantile Treasury Money Market Portfolio may only enter into repurchase
agreements in extraordinary circumstances.  The Mercantile Money Market
Portfolio may invest in obligations issued or guaranteed by U.S. Government and
its agencies and instrumentalities while the Firstar Money Market Fund may
invest in obligations issued or guaranteed by both U.S. and foreign governments
and their agencies and instrumentalities.  The Firstar Tax-Exempt Money Market
Fund is a diversified portfolio under the 1940 Act while the Mercantile Tax-
Exempt Money

                                      -58-
<PAGE>

Market Portfolio is a non-diversified portfolio under the 1940 Act. It is
expected that at the time of the Reorganization the Firstar U.S. Treasury Money
Market Fund will adopt an investment objective and certain non-fundamental
investment policies and restrictions that are substantially the same as those of
the Stellar Treasury Fund. See Exhibit A to Appendix III of this
Proxy/Prospectus for a complete description of the investment objective,
policies and restrictions of the Stellar Treasury Fund.

     Reorganizing Bond Funds.  The Firstar Intermediate Bond Market Fund invests
     -----------------------
in investment grade debt obligations, which are those rated in one of the top
four rating categories by one or more rating agencies, while the Mercantile
Intermediate Corporate Bond Portfolio, which also invests in investment grade
debt obligations, normally invests at least 65% of its total assets in debt
obligations rated in one of the three highest rating categories.  The Mercantile
Bond Index Portfolio and the Firstar Aggregate Bond Fund invest in similar debt
securities but utilize entirely different strategies.  The Mercantile Bond Index
Portfolio is not managed through the use of traditional methods of investment
management, but instead uses an "indexing" strategy through the use of computer
models to approximate the investment performance of the Lehman Aggregate Bond
Index.  The Firstar Aggregate Bond Fund is managed through the use of
traditional methods of investment management, such as market, economic and
security analysis.  Unlike the Mercantile Short-Intermediate Municipal
Portfolio, the Firstar Tax-Exempt Intermediate Bond Fund is required to invest
at least 65% of its total assets in bonds and debentures.  The average weighted
maturity is generally between 2 and 5 years for the Mercantile Short-
Intermediate Municipal Portfolio, while the average weighted maturity of the
Firstar Tax-Exempt Intermediate Bond Fund is generally between 3 and 10 years.

     It is expected that at the time of the Reorganization, the Firstar
Intermediate Bond Market Fund will be renamed the Firstar Intermediate Bond
Fund.

     Reorganizing Equity Funds.  Although actual percentages will vary from time
     -------------------------
to time, the Mercantile Balanced Portfolio's policy is to invest at least 25% of
its total assets in fixed-income securities and no more than 75% of its total
assets in equity securities, while the Firstar Balanced Growth Fund's policy is
to invest at least 25% of its total assets in fixed income securities and at
least 50% and no more than 65% of its total assets in equity securities.  The
Mercantile Balanced Portfolio's investments in equity securities are primarily
common stocks of companies with large market capitalizations, while the Firstar
Balanced Growth Fund's equity investments consist primarily of common stocks of
companies with market capitalizations between $100 million and $100 billion.
Both the Mercantile Equity Index Portfolio and the Firstar Equity Index Fund
include stocks in their respective portfolios based on such stocks' weightings
in the S&P 500 Index.  The Mercantile Equity Index Portfolio, unlike the Firstar
Equity Index Fund, may invest in index-based depository receipts in lieu of
investments in the actual securities listed in the S&P 500 Index.  Although many
of the stocks purchased by the Mercantile Growth & Income Equity Portfolio pay
dividends, income is not a major factor in the stock selection process for the
Portfolio.  By contrast, the Firstar Growth & Income Fund will not purchase a
non-dividend paying security if immediately after giving effect to such purchase
less than 80% of the net assets of the Fund will be invested in dividend paying
securities. The Firstar Growth & Income Fund normally invests at least 50% of
its net assets in equity securities, and these securities are generally those of
companies with market capitalizations of over $1 billion, while the Mercantile

                                      -59-
<PAGE>

Growth & Income Equity Portfolio invests primarily in common stocks with no
stated capitalization requirements.  The Mercantile Growth Equity Portfolio
generally invests at least 65% of its total assets in stocks or other equity
securities of large- and medium-capitalization companies, while the Firstar
Growth Fund normally invests at least 50% of its total assets in equity
securities with market capitalizations over $3 billion.  The Mercantile Small
Cap Equity Portfolio invests at least 65% of its total assets in small- to
medium-sized companies with market capitalizations from $100 million to $2
billion at the time of purchase, while the Firstar Emerging Growth Fund invests
at least 50% of its total assets in equity securities and these companies
generally have market capitalizations between $250 million and $2 billion. The
Firstar Core International Equity Fund normally invests at least 65% of its
total assets in securities of companies based in at least three different
countries other than the United States. The Mercantile International Equity Fund
normally invests at least 80% of its assets in the securities of issuers located
in at least three foreign countries with normally at least 50% of its total
assets invested in the securities of companies located in the developed
countries of Western Europe or Japan. The Firstar Core International Equity Fund
may not engage in options transactions whereas the Mercantile International
Equity Portfolio may engage in a wide range of options transactions. It is
expected that at the time of the Reorganization the Firstar Emerging Growth Fund
and the Firstar Core International Equity Fund will adopt investment objectives
and certain non-fundamental investment policies and restrictions that are
substantially the same as those of the Mercantile Small Cap Equity Portfolio and
Mercantile International Equity Portfolio, respectively.

     It is expected that at the time of the Reorganization, the Firstar Growth
Fund will be renamed the Firstar Large Cap Core Equity Fund, the Firstar
Emerging Growth Fund will be renamed the Firstar Small Cap Core Equity Fund and
the Firstar Core International Equity Fund will be renamed the Firstar
International Growth Fund.

     The investment objectives, policies and restrictions of the Mercantile
Funds and Firstar Funds are more fully discussed in Appendix III.  Additional
information about the investment policies and restrictions of the Mercantile
Funds and Firstar Funds is included in their respective prospectuses and
statements of additional information, which have been incorporated herein by
reference.

     Investment Advisory Services.  FIRMCO serves as investment adviser to the
Firstar Funds and Mercantile Funds will continue to serve as investment adviser
to the Firstar Funds upon consummation of the Reorganization.  Conning Asset
Management Company will serve as sub-adviser to the Firstar Conning Money Market
Fund upon consummation of the Reorganization.  It is expected that Clay Finlay
Inc. will replace The Glenmede Trust Company as sub-adviser to the Firstar Core
International Equity Fund prior to the Reorganization and will continue to serve
as sub-adviser to the Portfolio upon consummation of the Reorganization.

     The following table shows the contractual investment advisory and, where
applicable, sub-advisory fee ratios for each Mercantile Fund and its
Corresponding Firstar Fund.  The table also shows the respective investment
advisory and sub-advisory fee rates paid to the investment adviser and sub-
adviser after taking into account voluntary fee waivers.  The fees for the
Mercantile Funds are as of April 30, 2000.  The fees for the Firstar Funds (both
before and after

                                      -60-

waivers) represent the pro forma annualized advisory fees based upon fee
arrangements that will be in place upon consummation of the Reorganization.

Firstar Funds. For a more detailed comparison of the shareholder transactions

Shares, eleven of the fourteen Mercantile Funds that offer Institutional Shares,
seven of the eighteen Mercantile Funds that offer Trust Shares and none of the
Mercantile Funds that offer Trust II Shares will have total operating expense

the Mercantile Funds. For a comparison of the total return performance of the
Reorganizing Mercantile Funds with the Existing Firstar Funds, see Appendix V.

     Share Structure. Both Mercantile and Firstar are registered as open-end
management investment companies under the 1940 Act. Currently, Mercantile offers
nineteen funds. Firstar currently offers twenty-one funds and will offer thirty-
six funds immediately after the Reorganization (assuming that the Stellar
reorganization and the Select reorganization are also completed).

     Mercantile was organized as a Maryland corporation on September 9, 1982. It
is subject to the provisions of its Charter and By-Laws. Firstar was organized
as a Wisconsin corporation on February 15, 1988 and is subject to the provision
of its Charter and By-Laws. Mercantile's Charter authorizes the Board of
Directors to issue full and fractional shares of capital stock ($0.001 par value
per share) and to classify and reclassify any authorized and unissued shares
into one or more classes of shares. Firstar's Charter authorizes the Board of
Directors to issue full and fractional shares of capital stock ($0.0001 par
value per share) and to classify and reclassify any particular class of shares
into one or more additional series of shares. In general, the charter documents
governing Mercantile are similar to those documents governing Firstar. Although
the rights of a shareholder of a Maryland corporation may vary in certain
respects from the rights of a shareholder of a Wisconsin corporation, the
attributes of a share of common stock of each corporation are comparable, and
shares of both are entitled to one vote per share held and

                                      -68-
<PAGE>

fractional votes for fractional shares held, and will vote in the aggregate and
not by portfolio or class except as otherwise required by law or when class
voting is permitted by its Board.

     Additional information concerning the attributes of the shares issued by
Mercantile and Firstar is included in their respective prospectuses and
statements of additional information, which are incorporated herein by
reference. Information about the dividend and distribution policies of both the
Mercantile Funds and the Firstar Funds can be found in Appendix IV.

                                VOTING MATTERS


     General Information. The Board of Directors of Mercantile is furnishing
this Proxy/Prospectus in connection with the solicitation of proxies for the
Special Meeting. It is expected that the solicitation of proxies will be
primarily by mail. Officers and service contractors of Mercantile and Firstar
may also solicit proxies by telephone or otherwise. In this connection,
Mercantile has retained ADP Proxy Services ("ADP") and D.F. King & Co., Inc.
("D.F. King") to assist in the solicitation of proxies for the Reorganization.
Shareholders may vote (1) by mail, by marking, signing, dating and returning the
enclosed Proxy Ballot(s) in the enclosed postage-paid envelope, (2) by touch-
tone voting, or (3) by on-line voting. Any shareholder giving a proxy may revoke
it at any time before it is exercised by submitting to Mercantile a written
notice of revocation or a subsequently executed proxy or by attending the
Special Meeting and voting in person. As the Special Meeting date approaches,
certain shareholders of each Mercantile Fund may receive a telephone call from a
representative of D.F. King if their votes have not yet been received.
Authorization to permit ADP or D.F. King to execute proxies may be obtained by
telephonic or electronically transmitted instructions from shareholders of each
Fund. Proxies that are obtained telephonically will be recorded in accordance
with the procedures set forth below. The Directors believe 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 D.F. King
representative is required to ask for each shareholder's full name, address,
social security or employer identification number, title (if the shareholder is
authorized to act on behalf of an entity, such as a corporation), and the number
of shares owned, and to confirm that the shareholder has received the proxy
materials in the mail. If the information solicited agrees with the information
provided to D.F. King, then the D.F. King representative has the responsibility
to explain the process, read the proposals on the proxy card, and ask for the
shareholder's instructions on the proposals. Although he or she is permitted to
answer questions about the process, the D.F. King representative is not
permitted to recommend to the shareholder how to vote, other than to read any
recommendation set forth on the proxy statement. D.F. King will record the
shareholder's instructions on the card. Within 72 hours, the shareholder will be
sent a letter or mailgram to confirm his or her vote and asking the shareholder
to call D.F. King immediately if his or her instructions are not correctly
reflected in the confirmation.

                                      -69-
<PAGE>

     Any expenses incurred as a result of hiring ADP, D.F. King or any other
proxy solicitation agent will be borne by FIRMCO or its affiliates. It is
anticipated that the cost associated with using proxy solicitation agents will
be approximately $________.

     Only shareholders of record at the close of business on September 15, 2000
will be entitled to vote at the Special Meeting. On that date, the following
Mercantile shares were outstanding and entitled to be voted:

       Each whole and fractional share of a Mercantile Fund is entitled to a
whole or fractional vote as the case may be.

       If an accompanying proxy is executed and returned in time for the Special
Meeting, the shares covered thereby will be voted in accordance with the proxy
on all matters that may properly come before the Special Meeting.

       Shareholder and Board Approvals. The Reorganization Agreement is being
submitted for approval at the Meeting by Mercantile's shareholders pursuant to
Mercantile's Charter and By-Laws, and was unanimously approved by Mercantile's
Board of Directors at a meeting held on June 6, 2000, as ratified on July 11,
2000. The Reorganization Agreement must be approved by a majority of the
outstanding shares of each Mercantile Fund and the reorganization of Mercantile
must be approved by a majority of the outstanding shares of all the Mercantile
Funds. A vote for the Reorganization Agreement includes a vote for the
reorganization of Mercantile;

                                      -72-
<PAGE>

conversely, a vote against the Reorganization Agreement is a vote against the
reorganization of Mercantile.

     The Reorganization Agreement provides that in the event the Reorganization
Agreement is approved with respect to less than all of the Mercantile Funds, the
failure of a Mercantile Fund to consummate the transactions contemplated by the
Reorganization Agreement shall not affect the consummation or validity of the
Reorganization with respect to any other Mercantile Fund. It is possible that a
majority of a Mercantile Fund's shares may approve the Reorganization Agreement
while a majority of all shares of all Mercantile Funds voting in the aggregate
do not approve the reorganization of Mercantile. In such a case, the Board of
Directors of Mercantile will consider what further action is appropriate.

     With respect to the approval of the Reorganization Agreement, the term
"majority of the outstanding shares" of Mercantile or a Mercantile Fund means
more than 50% of the outstanding shares of Mercantile or the particular
Mercantile Fund. The vote of the shareholders of the Firstar Funds is not being
solicited, since their approval or consent is not necessary for the
Reorganization.

     Principal Shareholders. As of September 15, 2000, the officers and
Directors of Mercantile as a group owned or controlled less than 1% of each
Mercantile Fund's outstanding shares. As of September 15, 2000, the officers and
Directors of Firstar as a group owned or controlled less than 1% of each Firstar
Fund's outstanding shares. Table VI(A) shows the name, address and share
ownership of each person known to Mercantile to have beneficial or record
ownership with respect to 5% or more of a class of a Mercantile Fund as of
September 15, 2000. Table VI(B) shows the name, address and share ownership of
each person known to Firstar to have beneficial or record ownership, as of
September 15, 2000, with respect to 5% or more of a class of a Stellar Fund that
is expected to reorganize into a Firstar Fund along with a Mercantile Fund.
Table VI(C) shows the name, address and share ownership of each person known to
Firstar to have beneficial or record ownership with respect to 5% or more of a
class of a Firstar Fund as of September 15, 2000.

     The Firstar U.S. Government Securities Fund, Firstar Aggregate Bond Fund,
Firstar National Municipal Bond Fund and the Shell Firstar Funds had not
commenced investment

operations as of September 15, 2000 and, accordingly, no person owned 5% or more
of any such Firstar Fund.

     For purposes of the 1940 Act, any person who owns directly or through one
or more controlled companies more than 25% of the voting securities of a company
is presumed to "control" such company. Accordingly, to the extent that a
shareholder identified in the foregoing table is identified as the beneficial
holder of more than 25% of a class, or is identified as the holder of record of
more than 25% of a class and has voting and/or investment power, it may be
presumed to control such class.

     Firstar and Mercantile have been advised by Firstar Bank, N.A., an
affiliate of FIRMCO, that with respect to the shares of each Mercantile Fund
over which Firstar Bank, N.A. has voting power, such shares may be voted by
Firstar Bank, N.A. itself in its capacity as fiduciary.

     Quorum. In the event that a quorum is not present at the Special Meeting,
or in the event that a quorum is present at the Special Meeting but sufficient
votes to approve the Reorganization Agreement are not received by Mercantile or
by one or more of the Mercantile Funds, one or more adjournment(s) may be
proposed to permit further solicitation of proxies. Any adjourned session or
sessions may be held after the date set for the original Meeting without notice
except announcement at the Meeting, but under Maryland law, not more than 120
days after the record date. Any such adjournment(s) will require the affirmative
vote of a majority of those shares that are represented at the Meeting in person
or by proxy. If a quorum is present, the persons named as proxies will vote
those proxies which they are entitled to vote FOR the particular proposal for
which a quorum exists in favor of such adjournment(s), and will vote those
proxies required to be voted AGAINST such proposal against any adjournment(s).

     A quorum is constituted by the presence in person or by proxy of the
holders of more than 50% of the shares of Mercantile or the Mercantile Fund
entitled to vote at the Special Meeting. For purposes of determining the
presence of a quorum for transacting business at the Special Meeting,
abstentions will be recorded as shares that are present at the Special Meeting
but which have not been voted. Abstentions will have the effect of a "no vote"
for purposes of obtaining the requisite approval of the Reorganization
Agreement. Broker "non-votes" (that is, proxies from brokers or nominees
indicating that such persons have not received instructions from the beneficial
owners 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 the same as abstentions.

     Annual Meetings and Shareholder Meetings. Neither Mercantile nor Firstar
presently intends to hold annual meetings of shareholders for the election of
Directors and other business unless otherwise required by the 1940 Act. Under
certain circumstances, however, holders of at least 10% of the outstanding
shares of either Mercantile or Firstar have the right to call a meeting of
shareholders.

Funds and Firstar and the respective Firstar Funds. In determining the value of
the securities transferred by a Mercantile Fund to its Corresponding Firstar
Fund, each security shall be priced in

                                      -12-
<PAGE>

accordance with the pricing policies and procedures of such Mercantile Fund as
described in its then current prospectus(es) and statement of additional
information. For such purposes, price quotations and the security
characteristics relating to establishing such quotations shall be determined by
Mercantile, provided that such determination shall be subject to the approval of
Firstar. Firstar and Mercantile agree to use all commercially reasonable efforts
to resolve, prior to the Applicable Valuation Time, any material pricing
differences between the prices of portfolio securities determined in accordance
with the pricing policies and procedures of a Firstar Fund and those determined
in accordance with the pricing policies and procedures of its Corresponding
Mercantile Fund.

     (b) It is understood and agreed that the net asset value of the Assets of
those Mercantile Funds that are money market funds shall be based on the
amortized cost valuation procedures that have been adopted by the Board of
Directors of Mercantile; provided that if the difference between the per share
net asset values of any such Mercantile Fund and its Corresponding Firstar Fund
equals or exceeds $0.0010 at the Applicable Valuation Time, as computed by using
market values in accordance with the policies and procedures established by
Mercantile, either party shall have the right to postpone the Applicable
Valuation Time and Applicable Effective Time of the Reorganization (as
hereinafter defined) with respect to such Funds until such time as the per share
difference is less than $0.0010.

     (c) At least fifteen (15) business days prior to the Applicable Effective
Time of the Reorganization, each Mercantile Fund will provide its Corresponding
Firstar Fund with a schedule of its securities and other Assets and Liabilities
of which it is aware, and such Firstar

                                      -13-
<PAGE>

Fund will provide the Mercantile Fund with a copy of the current investment
objective and policies applicable to such Firstar Fund. Each Mercantile Fund
reserves the right to sell any of the securities or other Assets shown on the
list of the Fund's Assets prior to the Applicable Effective Time of the
Reorganization but will not, without the prior approval of Firstar, acquire any
additional securities other than securities which the Corresponding Firstar Fund
is permitted to purchase in accordance with its stated investment objective and
policies. At least ten (10) business days prior to the Applicable Effective Time
of the Reorganization, each Firstar Fund will advise its Corresponding
Mercantile Fund of any investments of such Mercantile Fund shown on such
schedule which the Firstar Fund would not be permitted to hold, pursuant to its
stated investment objective and policies or otherwise. In the event that the
Mercantile Fund holds any investments that its Corresponding Firstar Fund would
not be permitted to hold under its stated investment objective or policies, the
Mercantile Fund, if requested by the Firstar Fund and, to the extent permissible
and consistent with the Mercantile Fund's own investment objective and policies,
will dispose of such securities prior to the Applicable Effective Time of the
Reorganization. In addition, if it is determined that the portfolios of the
Mercantile Fund and the Firstar Fund, when aggregated, would contain investments
exceeding certain percentage limitations to which the Firstar Fund is or will be
subject with respect to such investments, the Mercantile Fund, if requested by
the Firstar Fund and to the extent permissible and consistent with the
Mercantile Fund's own investment objective and policies, will dispose of and/or
reinvest a sufficient amount of such investments as may be necessary to avoid
violating such limitations as of the Applicable Effective Time of the
Reorganization.

parties hereto. Notwithstanding anything herein to the contrary, in the event
that at an Applicable Valuation Time, (a) the New York Stock Exchange shall be
closed to trading or trading thereon 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 Firstar or Mercantile, accurate appraisal of the value of the
net assets of a Firstar Fund or a Mercantile Fund is impracticable, such

when trading shall have been fully resumed without restriction or disruption,

net assets of the Firstar Funds and the Mercantile Funds is practicable in the
judgment of Firstar and Mercantile.

                                  APPENDIX II

                    Expense Summaries of the Mercantile Funds
                         and Corresponding Firstar Funds

          The following tables (a) compare the fees and expenses as of April 30,
2000, for the Mercantile Funds and their Corresponding Firstar Funds and (b)
show the estimated fees and expenses for the Corresponding Firstar Funds on a
pro forma basis after giving effect to the Reorganization. The purpose of these
tables is to assist shareholders in understanding the various costs and expenses
that investors in these portfolios will bear as shareholders. The tables do not
reflect any charges that may be imposed by institutions directly on their
customer accounts in connection with investments in the portfolios. The fund
operating expense levels shown in this Proxy/Prospectus assume current net asset
levels; pro forma expense levels shown should not be considered an actual
representation of future expenses or performance. Such pro forma expense levels
project anticipated levels but may be greater or less than those shown.

          The Firstar Aggregate Bond Fund, Firstar U.S. Government Securities
Fund, Firstar National Municipal Bond Fund, Firstar Missouri Tax-Exempt Bond
Fund, Firstar Small Cap Index Fund, Firstar Equity Income Fund and Firstar
Conning Money Market Fund are new investment portfolios with nominal assets and
liabilities that will commence investment operations upon the completion of the
Reorganization.

          FIRMCO has committed to waiving/reimbursing fees as needed to ensure
that total operating expense ratios will not exceed the pro forma after waiver
expense ratios until October 31, 2001.

+    In the Reorganization, holders of each class of shares of the Mercantile
     Treasury Money Market Portfolio, and holders of Class Y Shares of the
     Firstar Stellar Treasury Fund, will each receive Institutional Shares of
     the Firstar U.S. Treasury Money Market Fund.

*    The Firstar Stellar Treasury Fund is expected to reorganize into the
     Firstar U.S. Treasury Money Market Fund in connection with the
     Reorganization. The reorganization of the Firstar Stellar Treasury Fund
     into the Firstar U.S. Treasury Money Market Fund and the Reorganization of
     the Mercantile Treasury Money Market Portfolio into the Firstar U.S.
     Treasury Money Market Fund will occur only if the shareholders of the
     appropriate Funds approve each transaction.

++   Institutional Shares will not be issued until the Applicable Effective Time
     of the Reorganization.

1.   It is expected that the Firstar U.S. Treasury Money Market Fund will change
     its investment policies upon consummation of the Reorganization and that it
     will continue the operations of the Firstar Stellar Treasury Fund.

2.   A fee of $15.00 is charged for each non-systematic withdrawal from a
     Retirement Account for which Firstar Bank, N.A. is custodian.

3.   Management Fees (after waivers) would be:

          Mercantile Treasury Money Market Portfolio...........0.35%

4.   "Other Expenses" for the Funds are expected to be less than the amounts
     shown above because certain service providers are voluntarily waiving a
     portion of their fees and/or reimbursing the Funds for certain "Other
     Expenses."

"Other Expenses" (after waivers) would be:

     *    This example should not be considered a representation of future
          expenses which may be more or less than those shown. The assumed 5%
          annual return is hypothetical and should not be considered a
          representation of past or future annual return. Actual return may be
          greater or less than the assumed amount. This example assumes that all
          dividends and other distributions are reinvested.

The purpose of the  foregoing  tables is to assist an investor in  understanding
the various  costs and expenses that an investor in the Funds will bear directly
or indirectly.

*    In the Reorganization, shareholders of each class of shares of the
     Mercantile Money Market Portfolio will receive Retail A Shares of the
     Firstar Money Market Fund.

     purchase and gradually declines until it is eliminated after six years.
     After six years, Mercantile Investor B Shares automatically convert to
     Investor A Shares.

2.   A fee of $12.00 is charged for each wire redemption (Retail A Shares) and
     $15.00 for each non-systematic withdrawal from a Retirement Account for

     *   This example should not be considered a representation of future
         expenses which may be more or less than those shown. The assumed 5%
         annual return is hypothetical and should not be considered a
         representation of past or future annual return. Actual return may be
         greater or less than the assumed amount. This example assumes that all
         dividends and other distributions are reinvested.

The purpose of the foregoing tables is to assist an investor in understanding
the various costs and expenses that an investor in the Funds will bear directly
or indirectly.

1.  The Firstar Conning Money Market Fund has not yet commenced operations. The
    Firstar Conning Market Fund will continue the operations of the Mercantile
    Conning Money Market Portfolio upon consummation of the Reorganization
    relating to that Fund.

2.  A fee of $15.00 is charged for each non-systematic withdrawal from a
    Retirement Account for which Firstar Bank, N.A. is custodian.

3.  Management Fees (after waivers) would be 0.17% for the Mercantile Conning
    Money Market Portfolio and the Combined Fund Pro Forma.

4.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses."

5.  As a result of the fee waivers and/or the expense reimbursements, the Total
    Fund Operating Expenses are expected to be less than the amounts shown

      *   The Firstar Stellar U.S. Government Income Fund is expected to
          reorganize into the Firstar U.S. Government Securities Fund in
          connection with the Reorganization. The reorganization of the Firstar
          Stellar U.S. Government Income Fund into the Firstar U.S. Government
          Securities Fund and the Reorganization of the Mercantile U.S.
          Government Securities Portfolio into the Firstar U.S. Government
          Securities Fund will only occur if the shareholders of the appropriate
          Funds approve each transaction.

      1.  The Firstar U.S. Government Securities Fund has not yet commenced
          operations. Upon consummation of the Reorganizations involving the
          Mercantile U.S. Government Securities Portfolio and the Firstar
          Stellar U.S. Government Securities Fund, the Firstar U.S. Government
          Securities Fund will continue the operations of the Mercantile U.S.
          Government Securities Portfolio.

      2.  This amount applies if you sell your shares in the first year after
          purchase and gradually declines until it is eliminated after six
          years. After six years, Firstar Stellar Class B Shares automatically

          fees for Class A Shares and Class B Shares for the current fiscal
          year.

     *    This example should not be considered a representation of future
          expenses which may be more or less than those shown. The assumed 5%
          annual return is hypothetical and should not be considered a
          representation of past or future annual return. Actual return may be
          greater or less than the assumed amount. This example assumes that all
          dividends and other distributions are reinvested.

The purpose of the foregoing tables is to assist an investor in understanding
the various costs and expenses that an investor in the Funds will bear directly

+  In the Reorganization, holders of Investor A Shares and Investor B Shares of
   the Mercantile U.S. Government Securities Portfolio will receive Retail A
   Shares and Retail B Shares, respectively, of the Firstar U.S. Government
   Securities Fund. In addition, holders of Class A Shares and Class B Shares of
   Firstar Stellar U.S. Government Income Fund who did not purchase their shares
   through an investment management, trust, custody, or other agency
   relationship with Firstar Bank, N.A., will receive Retail A Shares and Retail
   B Shares, respectively, of the Firstar U.S. Government Securities Fund.

*  The Firstar Stellar U.S. Government Income Fund is expected to reorganize
   into the Firstar U.S. Government Securities Fund in connection with the
   Reorganization. The reorganization of the Firstar Stellar U.S. Government
   Income Fund into the Firstar U.S. Government Securities Fund and the
   Reorganization of the Mercantile U.S. Government Securities Portfolio into
   the Firstar U.S. Government Securities Fund will only occur if the
   shareholders of the appropriate Funds approve each transaction.

                                     II-17
<PAGE>

1.  The Firstar U.S. Government Securities Fund has not yet commenced
    operations. Upon consummation of the Reorganizations involving the
    Mercantile U.S. Government Securities Portfolio and the Firstar Stellar U.S.
    Government Income Fund, the Firstar U.S. Government Securities Fund will
    continue the operations of the Mercantile U.S. Government Securities
    Portfolio.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Mercantile Investor B Shares automatically convert to Investor A
    Shares, Firstar Stellar Class B Shares automatically convert to Class A
    Shares, and the Combined Fund Pro Forma Retail B Shares automatically
    convert to Retail A Shares.

3.  A fee of $12.00 is charged for each wire redemption (Retail A Shares and
    Retail B Shares) and $15.00 for each non systematic withdrawal from a
    Retirement Account for which Firstar Bank, N.A. is custodian.

4.  Management Fees (after waivers) would be 0.50% for the Combined Fund Pro
    Forma.

5.  The Firstar Stellar U.S. Government Income Fund is waiving the 12b-1 fees
    for Class A Shares and Class B Shares for the current fiscal year.

6.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b 1 fees
    with respect to the Retail A Shares for the current fiscal year.

7.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses."

Other Expenses (after waivers) would be:

     *    This example should not be considered a representation of future
          expenses which may be more or less than those shown. The assumed 5%
          annual return is hypothetical and should not be considered a
          representation of past or future annual return. Actual return may be
          greater or less than the assumed amount. This example assumes that all
          dividends and other distributions are reinvested.

The purpose of the foregoing tables is to assist an investor in understanding
the various costs and expenses that an investor in the Funds will bear directly

 *   In the Reorganization, holders of Trust Shares of the Mercantile

     the Firstar Intermediate Bond Market Fund, holders of Institutional Shares
     of the Mercantile Intermediate Corporate Bond Portfolio will receive Class
     Y Shares of the Firstar Intermediate Bond Market Fund, and holders of
     Investor A Shares of the Mercantile Intermediate Corporate Bond Portfolio
     will receive Retail A Shares of the Firstar Intermediate Bond Market Fund.

 **  It is expected that at the time of the Reorganization, the Firstar
     Intermediate Bond Market Fund will be renamed the Firstar Intermediate Bond
     Fund.

 +   Class Y Shares will not be issued until the Reorganization is effective.

 1.  A fee of $12.00 is charged for each wire redemption (Retail A Shares) and
     $15.00 for each non systematic withdrawal from a Retirement Account for
     which Firstar Bank, N.A. is custodian.

3.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

4.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses."

*   In the Reorganization, holders of Investor A Shares of each of the Funds
    will receive Retail A Shares of the Firstar Aggregate Bond Fund, and holders
    of Investor B Shares of the Mercantile Government & Corporate Bond Portfolio
    will receive Retail B Shares of the Firstar Aggregate Bond Fund.

1.  The Firstar Aggregate Bond Fund has not yet commenced operations. In the
    Reorganization, the Mercantile Government & Corporate Bond Portfolio and the
    Mercantile Bond Index Portfolio will be combined into the Firstar Aggregate
    Bond Fund. Upon consummation of the Reorganization, the Firstar Aggregate
    Bond Fund will continue the operations of the Mercantile Government &
    Corporate Bond Portfolio.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Mercantile Investor B Shares automatically convert to Investor A
    Shares and Firstar Retail B Shares automatically convert to Retail A Shares.

3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares) and $15.00 for each non-systematic withdrawal from a Retirement
    Account for which Firstar Bank, N.A. is custodian.

4.  Management Fees (after waivers) would be 0.44% for the Combined Fund Pro
    Forma.

5.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

6.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses."

   *   This example should not be considered a representation of future expenses
       which may be more or less than those shown. The assumed 5% annual return
       is hypothetical and should not be considered a representation of past or
       future annual return. Actual return may be greater or less than the
       assumed amount. This example assumes that all dividends and other
       distributions are reinvested.

The purpose of the foregoing tables is to assist an investor in understanding
the various costs and expenses that an investor in the Funds will bear directly
or indirectly.

*  In the Reorganization, holders of Trust Shares of the Mercantile Missouri
   Tax-Exempt Bond Portfolio will receive Institutional Shares of the Firstar
   Missouri Tax-Exempt Bond Fund, holders of Investor A Shares of the Mercantile
   Missouri Tax-Exempt Bond Portfolio will receive Retail A Shares of the
   Firstar Missouri Tax-Exempt Bond Fund, and holders of Investor B Shares of
   the Mercantile Missouri Tax-Exempt Bond Portfolio will receive Retail B
   Shares of the Firstar Missouri Tax Exempt-Bond Fund.

    Reorganization relating to that Fund.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Mercantile Investor B Shares automatically convert to Investor A
    Shares and Firstar Retail B Shares automatically convert to Retail A Shares.

+  In the Reorganization, holders of Trust Shares of the Mercantile National

   the Firstar Stellar Insured Tax-Free Bond Fund who purchased their shares
   through an investment management, trust, custody, or other agency
   relationship with Firstar Bank, N.A., will each receive Institutional Shares
   of the Firstar National Municipal Bond Fund.

*  The Firstar Stellar Insured Tax-Free Bond Fund is expected to reorganize into
   the Firstar National Municipal Bond Fund in connection with the
   Reorganization. The reorganization of the Firstar Stellar Insured Tax-Free
   Bond Fund into the Firstar National Municipal Bond Fund and the
   Reorganization of the Mercantile National Municipal Bond Portfolio into the
   Firstar National Municipal Bond Fund will only occur if the shareholders of
   the appropriate Funds approve each transaction.

1.  The Firstar National Municipal Bond Fund has not yet commenced operations.
    Upon consummation of the Reorganizations involving the Mercantile National
    Municipal Bond Portfolio and the Firstar Stellar Insured Tax-Free Bond Fund,
    the Firstar National Municipal Bond Fund will continue the operations of the
    Mercantile National Municipal Bond Portfolio.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Firstar Stellar Class B Shares automatically convert to Class A
    Shares.

3.  Management Fees (after waivers) would be 0.55% for the Firstar Stellar
    Insured Tax-Free Bond Fund.

4.  The Firstar Stellar Insured Tax-Free Bond Fund does not intend to pay 12b-1
    fees with respect to the Class A Shares and Class B Shares for the current
    fiscal year.

5.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses."

Other Expenses (after waivers) would be:

6.  As a result of the fee waivers and/or the expense reimbursements, the Total
    Fund Operating Expenses are expected to be less than the amounts shown
    above. These fee waivers and/or reimbursements are made in order to keep the
    annual fees and expenses of the Funds at a certain level.

Total Fund Operating Expenses (after waivers) would be:

+  In the Reorganization, holders of Investor A Shares and Investor B Shares of
   the Mercantile National Municipal Bond Portfolio will receive Retail A Shares
   and Retail B Shares, respectively, of the Firstar National Municipal Bond
   Fund. In addition, holders of Class A Shares and Class B Shares of Firstar
   Stellar Insured Tax-Free Bond Fund who did not purchase their shares through
   an investment management, trust, custody, or other agency relationship with
   Firstar Bank, N.A., will receive Retail A Shares and Retail B Shares,
   respectively, of the Firstar National Municipal Bond Fund.

*  The Firstar Stellar Insured Tax-Free Bond Fund is expected to reorganize into
   the Firstar National Municipal Bond Fund in connection with the
   Reorganization. The reorganization of the Firstar Stellar Insured Tax-Free
   Bond Fund into the Firstar National Municipal Bond Fund and the
   Reorganization of the Mercantile National Municipal Bond Portfolio into the
   Firstar National Municipal Bond Fund will only occur if the shareholders of
   the appropriate Funds approve each transaction.

1.  The Firstar National Municipal Bond Fund has not yet commenced operations.
    Upon consummation of the Reorganizations involving the Mercantile National
    Municipal Bond Portfolio and the Firstar Stellar Insured Tax-Free Bond Fund,
    the Firstar National Municipal Bond Fund will continue the operations of the
    Mercantile National Municipal Bond Portfolio.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Mercantile Investor B Shares automatically convert to Investor A
    Shares, Firstar Stellar Class B Shares automatically convert to Class A
    Shares and Firstar Retail B Shares automatically convert to Retail A Shares.

3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares).

4.  Management Fees (after waivers) would be 0.55% for the Firstar Stellar
    Insured Tax-Free Bond Fund.

5.  Distribution and Service (12b-1) Fees (after waivers) would be:

6.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

7.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses."

*  In the Reorganization, holders of Investor A Shares and Investor B Shares of
   the Mercantile Balanced Portfolio will receive Retail A Shares and Retail B
   Shares, respectively, of the Firstar Balanced Growth Fund.

1. This amount applies if you sell your shares in the first year after purchase
   and gradually declines until it is eliminated after six years. After six
   years, Mercantile Investor B Shares automatically convert to Investor A
   Shares and Firstar Retail B Shares automatically convert to Retail A Shares.

2. A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
   Shares) and $15.00 for each non systematic withdrawal from a Retirement
   Account for which Firstar Bank, N.A. is custodian.

3.  Management Fees (after waivers) would be:

        Firstar Balanced Growth Fund....................0.70%
        Combined Fund Pro Forma.........................0.71%

4.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

5.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses."

Other Expenses (after waivers) would be:

6.  As a result of the fee waivers and/or the expense reimbursements, the Total
    Fund Operating Expenses are expected to be less than the amounts shown
    above. These fee waivers and/or reimbursements are made in order to keep the
    annual fees and expenses of the Funds at a certain level.

*   In the Reorganization, holders of Trust Shares of the Mercantile Equity
    Income Portfolio will receive Institutional Shares of the Firstar Equity
    Income Fund, holders of Institutional Shares of the Mercantile Equity Income
    Portfolio will receive Class Y Shares of the Firstar Equity Income Fund,
    holders of Investor A Shares of the Mercantile Equity Income Portfolio will
    receive Retail A Shares of the Firstar Equity Income Fund, and holders of
    Investor B Shares of the Mercantile Equity Income Portfolio will receive
    Retail B Shares of the Firstar Equity Income Fund.

1.  The Firstar Equity Income Fund has not yet commenced operations. The Firstar
    Equity Income Fund will continue the operations of the Mercantile Equity
    Income Portfolio upon consummation of the Reorganization relating to that
    Fund.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Mercantile Investor B Shares automatically convert to Investor A
    Shares and Firstar Retail B Shares automatically convert to Retail A Shares.

                                     II-48

3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares) and $15.00 for each non systematic withdrawal from a Retirement
    Account for which Firstar Bank, N.A. is custodian.

4.  Management Fees (after waivers) would be 0.72% for the Combined Fund Pro
    Forma.

5.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

6.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses."

* In the Reorganization, holders of Investor A Shares and Investor B Shares of
   the Mercantile Growth & Income Equity Portfolio will receive Retail A Shares
   and Retail B Shares, respectively, of the Firstar Growth and Income Fund.

1. This amount applies if you sell your shares in the first year after purchase
   and gradually declines until it is eliminated after six years. After six
   years, Mercantile Investor B Shares automatically convert to Investor A
   Shares and Firstar Retail B Shares automatically convert to Retail A Shares.

2. A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
   Shares) and $15.00 for each non systematic withdrawal from a Retirement
   Account for which Firstar Bank, N.A. is custodian.

3. The total of all 12b-1 fees and shareholder servicing fees may not exceed, in
   the aggregate, the annual rate of 0.25% of the Fund's average daily net
   assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
   with respect to the Retail A Shares for the current fiscal year.

4. "Other Expenses" for the Funds are expected to be less than the amounts shown
   above because certain service providers are voluntarily waiving a portion of
   their fees and/or reimbursing the Funds for certain "Other Expenses."

"Other Expenses" (after waivers) would be:

5. As a result of the fee waivers and/or the expense reimbursements, the Total
   Fund Operating Expenses are expected to be less than the amounts shown above.
   These fee waivers and/or reimbursements are made in order to keep the annual
   fees and expenses of the Funds at a certain level.

* In the Reorganization, holders of Investor A Shares and Investor B Shares of
  the Mercantile Growth Equity Portfolio will receive Retail A Shares and Retail
  B Shares, respectively, of the Firstar Growth Fund.

**It is expected that at the time of the Reorganization, the Firstar Growth Fund
  will be renamed the Firstar Large Cap Core Equity Fund.

     1.  This amount applies if you sell your shares in the first year after
         purchase and gradually declines until it is eliminated after six years.
         After six years, Mercantile Investor B Shares automatically convert to
         Investor A Shares and Firstar Retail B Shares automatically convert to
         Retail A Shares.

     2.  A fee of $12.00 is charged for each wire redemption (Retail A and
         Retail B Shares) and $15.00 for each non systematic withdrawal from a
         Retirement Account for which Firstar Bank, N.A. is custodian.

     3.  The total of all 12b-1 fees and shareholder servicing fees may not
         exceed, in the aggregate, the annual rate of 0.25% of the Fund's
         average daily net assets for the Retail A Shares. The Fund does not
         expect to pay 12b-1 fees with respect to the Retail A Shares for the
         current fiscal year.

     4.  "Other Expenses" for the Funds are expected to be less than the amounts
          shown above because certain service providers are voluntarily waiving
          a portion of their fees and/or reimbursing the Funds for certain
          "Other Expenses."

     "Other Expenses" (after waivers) would be:

     5.  As a result of the fee waivers and/or the expense reimbursements, the
         Total Fund Operating Expenses are expected to be less than the amounts
         shown above. These fee waivers and/or reimbursements are made in order
         to keep the annual fees and expenses of the Funds at a certain level.

*  In the Reorganization, holders of Investor A Shares and Investor B Shares of
   the Mercantile Small Cap Equity Portfolio will receive Retail A Shares and
   Retail B Shares, respectively, of the Firstar Emerging Growth Fund.

                                     II-69
<PAGE>

1.  It is expected that the Firstar Emerging Growth Fund will change its
    investment policies upon consummation of the Reorganization and that it will
    continue the operations of the Mercantile Small Cap Equity Portfolio. In
    addition, it is expected that at the time of the Reorganization, the Firstar
    Emerging Growth Fund will be renamed the Firstar Small Cap Core Equity Fund.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Mercantile Investor B Shares automatically convert to Investor A
    Shares and Firstar Retail B Shares automatically convert to Retail A Shares.

3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares) and $15.00 for each non-systematic withdrawal from a Retirement
    Account for which Firstar Bank, N.A. is custodian.

4.  Management Fees (after waivers) would be 0.74% for the Combined Fund Pro
    Forma.

5.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

6.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses".

"Other Expenses" (after waivers) would be:

*  In the Reorganization, holders of Trust Shares of the Mercantile

+ Class Y Shares will not be issued until the Applicable Effective Time of the
Reorganization.

1.  It is expected that the Firstar Core International Equity Fund will change
    its investment policies upon consummation of the Reorganization and that it
    will continue the operations of the Mercantile International Equity
    Portfolio. In addition, it is expected that at the time of the
    Reorganization, the Firstar Core International Equity Fund will be renamed
    the Firstar International Growth Fund.

2.  A fee of $15.00 is charged for each non-systematic withdrawal from a
Retirement Account for which Firstar Bank, N.A. is custodian.

3.  Management Fees (after waivers) would be:

             Mercantile International Equity Portfolio..................0.94%
             Firstar Core International Equity Fund.....................0.83%
             Combined Fund Pro Forma....................................0.94%

4.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses".

"Other Expenses" (after waivers) would be:

5.  As a result of the fee waivers and/or the expense reimbursements, the Total
    Fund Operating Expenses are expected to be less than the amounts shown
    above. These fee waivers and/or reimbursements are made in order to keep the
    annual fees and expenses of the Funds at a certain level.

Total Fund Operating Expenses (after waivers) would be:

                                   II-78
<PAGE>

1.  It is expected that the Firstar Core International Equity Fund will change
    its investment policies upon consummation of the Reorganization and that it
    will continue the operations of the Mercantile International Equity
    Portfolio. In addition, it is expected that at the time of the
    Reorganization, the Firstar Core International Equity Fund will be renamed
    the Firstar International Growth Fund.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Mercantile Investor B Shares automatically convert to Investor A
    Shares and Firstar Retail B Shares automatically convert to Retail A Shares.

3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares) and $15.00 for each non systematic withdrawal from a Retirement
    Account for which Firstar Bank, N.A. is custodian.

4.  Management Fees (after waivers) would be:

          Mercantile International Equity Portfolio......0.94%
          Firstar Core International Equity Fund.........0.83%
          Combined Fund Pro Forma....................... 0.94%

5. The Firstar Core International Equity Fund and Combined Fund Pro Forma do not
   intend to pay 12b-1 fees with respect to the Retail A Shares.

6. "Other Expenses" for the Funds are expected to be less than the amounts shown
    above because certain service providers are voluntarily waiving a portion of
    their fees and/or reimbursing the Funds for certain "Other Expenses."

"Other Expenses" (after waivers) would be:

       -----------------------------------------------------------------------

          Mercantile International Equity Portfolio      0.32%       0.32%
       -----------------------------------------------------------------------

7.  As a result of the fee waivers and/or the expense reimbursements, the Total
    Fund Operating Expenses are expected to be less than the amounts shown
    above. These fee waivers and/or reimbursements are made in order to keep the
    annual fees and expenses of the Funds at a certain level.

Total Fund Operating Expenses (after waivers) would be:

                                 APPENDIX III

                Investment Objectives, Limitations and Certain
              Significant Investment Policies of the Reorganizing
               Mercantile Funds and Corresponding Firstar Funds

     This Appendix highlights the investment objectives and certain significant
similarities and differences among the investment limitations and policies of
certain of the Reorganizing Mercantile Funds and their Corresponding Firstar
Funds. Because the Mercantile Conning Money Market Portfolio, Mercantile
Missouri Tax-Exempt Bond Portfolio, Mercantile Equity Income Portfolio and
Mercantile Small Cap Equity Index Portfolio will be reorganized into Shell
Firstar Funds that have substantially the same investment objectives, policies
and restrictions as their corresponding Continuing Mercantile Funds, they are
not discussed in this Appendix. Similarly, because (i) the Mercantile U.S.
Government Securities Portfolio, together with the Stellar U.S. Government
Income Fund, will reorganize into the Firstar U.S. Government Securities Fund,
which has substantially the same investment objective, policies and restrictions
as the Mercantile U.S. Government Securities Portfolio, (ii) the Mercantile
Government & Corporate Bond Portfolio, together with the Mercantile Bond Index
Portfolio, will reorganize into the Firstar Aggregate Bond Fund, which has
substantially the same investment objective, policies and restrictions as the
Mercantile Government & Corporate Bond Portfolio, and (iii) the Mercantile
National Municipal Bond Portfolio, together with the Stellar Insured Tax-Free
Bond Fund, will reorganize into the Firstar National Municipal Bond Fund, which
has substantially the same investment objective, policies and restrictions as
the Mercantile National Municipal Bond Portfolio, the Mercantile U.S. Government
Securities Portfolio, Mercantile Government & Corporate Bond Portfolio and
Mercantile National Municipal Bond Portfolio are not discussed in this Appendix.
The following is qualified in its entirety by the more detailed information
included in the prospectuses and statements of additional information for the
Mercantile Funds and the Corresponding Firstar Funds which are incorporated by
reference into this Proxy/Prospectus.

1.   MERCANTILE TREASURY MONEY MARKET PORTFOLIO/FIRSTAR U.S. TREASURY MONEY
     MARKET FUND

     Investment Objectives:

     (a)  Mercantile Treasury Money Market Portfolio:  Seeks a high level of
          ------------------------------------------
          current income exempt from state income tax consistent with liquidity
          and security of principal. This investment objective is fundamental
          and may not be changed without the approval of the Portfolio's
          shareholders.

     (b)  Stellar Treasury Fund:  Seeks to achieve stability of principal and
          ---------------------
          current income consistent with stability of principal. This investment
          objective is fundamental and may not be changed without the approval
          of the Fund's shareholders.

     (c)  Firstar U.S. Treasury Money Market Fund:  Sees to provide a high level
          ---------------------------------------
          of taxable current income exempt from state income taxes consistent
          with liquidity,
<PAGE>

          the preservation of capital and a stable net asset value. This
          investment objective is not fundamental and may be changed by the
          Firstar Board of Directors without shareholder approval.

     Comment:  Both the Mercantile Treasury Money Market Portfolio and the
Stellar Treasury Fund will reorganize into the Firstar U.S. Treasury Money
Market Fund. It is expected that at the time of the Reorganization the Firstar
U.S. Treasury Money Market Fund will adopt an investment objective and certain
non-fundamental investment policies and restrictions that are substantially the
same as those of the Stellar Treasury Fund. Accordingly, set forth below is a
description of the significant similarities and differences between the
investment objective, policies and restrictions of the Mercantile Treasury Money
Market Portfolio and (i) the existing investment objective, policies and
restrictions of the Firstar U.S. Treasury Money Market Fund and (ii) the
investment objective, policies and restrictions of the Stellar Treasury Fund
that are expected to be adopted by the Firstar U.S. Treasury Money Market Fund.
For a complete description of the investment objective, policies and
restrictions of the Stellar Treasury Fund, see Exhibit A to this Appendix.

     Mercantile Treasury Money Market Portfolio/Firstar U.S. Treasury Money
Market Fund. The Mercantile Treasury Money Market Portfolio and the Firstar U.S.
Treasury Money Market Fund each is a money market fund and in accordance with
Rule 2a-7 under the 1940 Act will generally invest in instruments with remaining
maturities not exceeding 397 days. Each Fund's dollar-weighted average portfolio
maturity may not exceed 90 days. The Mercantile Treasury Money Market Portfolio
invests substantially all, but not less than 65%, of its total assets in money
market instruments issued by the U.S. Treasury and certain U.S. Government
agencies and instrumentalities that provide income that is generally not subject
to state income tax. During normal market conditions, the Firstar U.S. Treasury
Money Market Fund invests at least 65% of its total assets in short-term,
dollar-denominated debt obligations issued or guaranteed as to principal and
interest by the U.S. Treasury. The Firstar U.S. Treasury Money Market Fund also
may invest in repurchase agreements, reverse repurchase agreements and other
investment companies. The Mercantile Treasury Money Market Portfolio generally
does not invest in repurchase agreements, reverse repurchase agreements or other
investment companies, although it may enter into repurchase agreements and
invest in other investment companies in extraordinary circumstances. Unlike the
Firstar U.S. Treasury Money Market Fund, the Mercantile Treasury Money Market
Portfolio may purchase securities on a when-issued basis and purchase and sell
securities on a forward commitment basis.

     The Firstar U.S. Treasury Money Market Fund may lend its portfolio
securities in an amount not to exceed 30% of the value of its total assets while
the Mercantile Treasury Money Market Portfolio may lend its portfolio securities
in an amount not to exceed 33-1/3% of the value of its total assets.

     Mercantile Treasury Money Market Portfolio/Stellar Treasury Fund.  The
Mercantile Treasury Money Market Portfolio and the Stellar Treasury Fund each is
a money market fund and in accordance with Rule 2a-7 under the 1940 Act will
generally invest in instruments with remaining maturities not exceeding 397
days. Each Fund's dollar-weighted average portfolio maturity may not exceed 90
days.  The Mercantile Treasury Money Market Portfolio invests

                                      -2-
<PAGE>

substantially all, but not less than 65%, of its total assets in money market
instruments issued by the U.S. Treasury and certain U.S. Government agencies and
instrumentalities that provide income that is generally not subject to state
income tax. The Stellar Treasury Fund invests exclusively in short-term U.S.
Treasury obligations. The Stellar Treasury Fund also may invest in repurchase
agreements collateralized by U.S. Treasury obligations, reverse repurchase
agreements and other investment companies. The Mercantile Treasury Money Market
Portfolio generally does not invest in repurchase agreements, reverse repurchase
agreements or other investment companies, although it may enter into repurchase
agreements and invest in other investment companies in extraordinary
circumstances.

     The Mercantile Treasury Money Market Portfolio may lend its portfolio
securities in an amount not to exceed 33-1/3% of the value of its total assets,
while the Stellar Treasury Fund may not lend its portfolio securities.  The
Mercantile Treasury Money Market Portfolio may borrow money from banks for
temporary purposes in an amount not exceeding 10% of the value of its total
assets at the time of the borrowing.  The Stellar Treasury Fund may borrow money
as a temporary, extraordinary or emergency measure or to facilitate Fund
management in an amount not exceeding 33-1/3% of the value of its total assets.

2.   MERCANTILE MONEY MARKET PORTFOLIO/ FIRSTAR MONEY MARKET FUND

     Investment Objectives:

     (a)  Mercantile Money Market Portfolio:  Seeks current income with
          ---------------------------------
          liquidity and stability of principal. This investment objective is
          fundamental and may not be changed without the approval of the
          Portfolio's shareholders.

     (b)  Firstar Money Market Fund:  Seeks to provide a high level of taxable
          -------------------------
          current income consistent with liquidity, the preservation of capital
          and a stable net asset value. This investment objective is not
          fundamental and may be changed by the Firstar Board of Directors
          without shareholder approval.

     Comment: The Mercantile Money Market Portfolio and the Firstar Money Market
Fund each is a money market fund and in accordance with Rule 2a-7 under the 1940
Act will generally invest in instruments with remaining maturities not exceeding
397 days. Each Fund's dollar-weighted average portfolio maturity may not exceed
90 days. Both the Mercantile Money Market Portfolio and the Firstar Money Market
Fund will purchase only those securities that are rated in the highest short-
term rating category (i.e., rated AAA by Standard & Poor's Ratings Group ("S&P")
or Aaa by Moody's Investors Service Inc. ("Moody's")) by at least two nationally
recognized rating agencies (or one such rating if only one agency has rated the
instrument) or that are determined to be of comparable quality.

     The Mercantile Money Market Portfolio invests substantially all (but not
less than 80%) of its total assets in a broad range of U.S. dollar-denominated
money market instruments, including commercial paper, notes and bonds issued by
U.S. and foreign corporations, obligations issued by the U.S. Government and its
agencies and instrumentalities, and

                                      -3-
<PAGE>

obligations issued by U.S. and foreign banks, such as certificates of deposit,
letters of credit, bankers' acceptances and time deposits. The Mercantile Money
Market Portfolio may also invest in repurchase agreements, reverse repurchase
agreements, stripped U.S. Government securities, certain variable and floating
rate securities and securities of other investment companies.

     The Firstar Money Market Fund invests principally in short-term, high
quality, dollar-denominated money market debt obligations. These obligations may
be issued by entities including domestic and foreign corporations, banks and
other financial institutions, or they may be issued or guaranteed by the U.S.
Government and its agencies and instrumentalities. Unlike the Mercantile Money
Market Portfolio, the Firstar Money Market Fund may invest in obligations issued
by foreign governments and their agencies, instrumentalities and political
subdivisions and short-term funding agreements. The Firstar Money Market Fund
may lend its portfolio securities in an amount not to exceed 30% of the value of
its total assets while the Mercantile Money Market Portfolio may lend its
portfolio securities in an amount not to exceed 33-1/3% of the value of its
total assets.

3.   MERCANTILE TAX-EXEMPT MONEY MARKET PORTFOLIO/FIRSTAR TAX-EXEMPT MONEY
     MARKET FUND

     Investment Objectives:

     (a)  Mercantile Tax-Exempt Money Market Portfolio:  Seeks as high a level
          --------------------------------------------
          of current interest income exempt from federal income tax as is
          consistent with liquidity and stability of principal. This investment
          objective is fundamental and may not be changed without the approval
          of the Portfolio's shareholders.

     (b)  Firstar Tax-Exempt Money Market Fund:  Seeks to provide a high level
          ------------------------------------
          of current income exempt from federal income taxes consistent with
          liquidity, the preservation of capital and a stable net asset value.
          This investment objective is not fundamental and may be changed by the
          Firstar Board of Directors without shareholder approval.

     Comment:  Both the Mercantile Tax-Exempt Money Market Portfolio and the
Stellar Tax-Free Money Market Fund will reorganize into the Firstar Tax-Exempt
Money Market Fund.

     The Mercantile Tax-Exempt Money Market Portfolio and the Firstar Tax-Exempt
Money Market Fund each is a money market fund and in accordance with Rule 2a-7
under the 1940 Act will generally invest in instruments with remaining
maturities not exceeding 397 days. Each Fund's dollar-weighted average portfolio
maturity may not exceed 90 days. Both the Mercantile Tax-Exempt Money Market
Portfolio and the Firstar Tax-Exempt Money Market Fund will purchase only
securities which are rated in the highest short-term rating category (i.e.,
rated AAA by S&P or Aaa by Moody's by at least two nationally recognized rating
agencies (or one such rating if only one agency has rated the instrument) or
that are determined to be of comparable quality.

                                      -4-
<PAGE>

     The Mercantile Tax-Exempt Money Market Portfolio normally invests (as a
matter of fundamental policy which cannot be changed without shareholder
approval) at least 80% of its total assets in short-term municipal securities
issued by or on behalf of states, territories and possessions of the United
States, the District of Columbia and their authorities, instrumentalities,
agencies and political subdivisions and that pay interest which is exempt from
federal income tax. Investments by the Mercantile Tax-Exempt Money Market
Portfolio in private activity bonds, the interest on which may be subject to the
federal alternative minimum tax, will not be treated as investments in municipal
securities for purposes of the 80% requirement stated above and, under normal
conditions, will not exceed 20% of the Portfolio's total assets when added with
any taxable investments.

     The Firstar Tax-Exempt Money Market Fund invests (as a matter of
fundamental policy which cannot be changed without shareholder approval) at
least 80% of its net assets in municipal securities issued by or on behalf of
states, territories and possessions of the United States, the District of
Columbia and their authorities, instrumentalities, agencies and political
subdivisions, which are exempt from federal income taxes and with remaining
maturities of 13 months or less. The municipal securities in which the Firstar
Tax-Exempt Money Market Fund may invest are generally the same as those eligible
for investment by the Mercantile Tax-Exempt Money Market Portfolio, except that
the Firstar Tax-Exempt Money Market Fund may not invest in tax-exempt derivative
securities, such as tender option bonds, participations, beneficial interests in
trusts and partnership interests.

     The Firstar Tax-Exempt Money Market Fund, like the Mercantile Tax-Exempt
Money Market Portfolio, normally may invest no more than 20% of its total assets
in taxable obligations. Taxable obligations in which the Firstar Tax-Exempt
Money Market Fund may invest are generally the same as those eligible for
investment by the Mercantile Tax-Exempt Money Market Portfolio, except that the
Firstar Tax-Exempt Money Market Fund may not invest in bank obligations, such as
certificates of deposit and bankers' acceptances, stripped U.S. Government
securities and repurchase agreements. The Firstar Tax-Exempt Money Market Fund
may lend its portfolio securities in an amount not to exceed 30% of the value of
its total assets, whereas the Mercantile Tax-Exempt Money Market Portfolio may
not lend its portfolio securities.

     The Firstar Tax-Exempt Money Market Fund is diversified, whereas the
Mercantile Tax-Exempt Money Market Portfolio is not-diversified, which means
that it may invest a relatively high percentage of its assets in the obligations
of a limited number of issuers.

4.   MERCANTILE INTERMEDIATE CORPORATE BOND PORTFOLIO/FIRSTAR INTERMEDIATE BOND
     MARKET FUND

     Investment Objectives:

     (a)  Mercantile Intermediate Corporate Bond Portfolio:  Seeks as high a
          ------------------------------------------------
          level of current income as is consistent with preservation of capital.
          This investment objective is fundamental and may not be changed
          without the approval of the Portfolio's shareholders.

                                      -5-
<PAGE>

     (b)  Firstar Intermediate Bond Market Fund:  Seeks to provide an annual
          -------------------------------------
          rate of total return, before Fund expenses, comparable to the annual
          rate of total return of the Lehman Brothers Intermediate
          Government/Corporate Bond Index. This investment objective is not
          fundamental and may be changed by Firstar's Board of Directors without
          shareholder approval.

     Comment:  It is expected that at the time of the Reorganization, the
Firstar Intermediate Bond Market Fund will be renamed the Firstar Intermediate
Bond Fund.

     The Mercantile Intermediate Corporate Bond Portfolio normally invests at
least 65% of its total assets in corporate debt obligations.  These include
obligations that are issued by U.S. and foreign business corporations and
obligations issued by agencies, instrumentalities or authorities that are
organized as corporations by the U. S., by states or political subdivisions of
the U.S., or by foreign governments or political subdivisions.  The Mercantile
Intermediate Corporate Bond Portfolio also may invest in obligations issued or
guaranteed by U.S. or foreign governments, their agencies and instrumentalities
and in mortgage-backed securities, including collateralized mortgage
obligations.  The Fund may only purchase investment grade debt obligations
(i.e., those rated BBB or higher by S&P or Baa or higher by Moody's) or unrated
debt obligations determined to be of comparable quality.  Under normal market
conditions, the Portfolio invests at least 65% of its total assets in debt
obligations rated in one of the top three rating categories (i.e., A or higher
by S&P or Moody's) or unrated debt obligations determined to be of comparable
quality.  The Mercantile Intermediate Corporate Bond Portfolio's average
weighted maturity will generally be between 3 and 10 years.

     The Firstar Intermediate Bond Market Fund attempts to make its duration and
return comparable to, and to maintain an overall interest rate sensitivity
equivalent to, that of the Lehman Brothers Intermediate Government/Corporate
Bond Index (the "Lehman Index"). To this end, the Fund invests at least 65% of
its total assets in debt securities, including securities issued or guaranteed
by the U.S. Government and its agencies, stripped U.S. Government securities,
corporate securities,, medium-term notes, collateralized mortgage obligations,
asset-backed and mortgage-backed obligations and Eurobonds. The Fund typically
holds less than 200 securities. The Fund is not an index fund, however, and may
                                            ---
invest more than 50% of its assets in securities not included in the Lehman
Index. Debt obligations purchased by the Fund will be rated investment grade
(i.e., BBB or higher by S&P or Baa or higher by Moody's) or unrated obligations
determined to be of comparable quality. The average quality for the Fund is
expected to be at least the second highest rating category of S&P or Moody's.
The effective dollar-weighted average portfolio maturity of the Firstar
Intermediate Bond Market Fund will be more than 3 years but less than 10 years
during normal market conditions.

     Unlike the Mercantile Intermediate Corporate Bond Portfolio, the Firstar
Intermediate Bond Market Fund may invest in unlisted over-the-counter options,
preferred stocks and guaranteed investment contracts. The Mercantile
Intermediate Corporate Bond Portfolio, unlike the Firstar Intermediate Bond
Market Fund, may invest in convertible debt securities. The Firstar Intermediate
Bond Market Fund may invest no more than 50% of its net assets in collateralized
mortgage obligations, whereas there is no limit on the amount of the Mercantile
Intermediate Corporate Bond Portfolio's assets that may be invested in such
obligations. The

Mercantile Intermediate Corporate Bond Portfolio may lend its portfolio
securities in an amount not to exceed 33-1/3% of the value of its total assets,
while the Firstar Intermediate Bond Market Fund may lend its portfolio
securities in an amount not to exceed 30% of the value of its total assets.

     The Mercantile Intermediate Corporate Bond Portfolio may purchase put and
call options on particular securities or bond indices for hedging purposes in an
amount not to exceed 10% of its net assets.  The Firstar Intermediate Bond
Market Fund may purchase put and call options on particular securities or
indices to manage exposure to certain markets, enhance income or for hedging
purposes in an amount not to exceed 5% of its net assets.  The Mercantile
Intermediate Corporate Bond Portfolio may write covered call options in an
amount not to exceed 25% of its net assets, while covered call options written
by the Firstar Intermediate Bond Market Fund may not exceed 5% of its net
assets.

5.   MERCANTILE BOND INDEX PORTFOLIO/FIRSTAR AGGREGATE BOND FUND

     Investment Objectives:

     (a)  Mercantile Bond Index Portfolio:  Seeks to provide investment results
          -------------------------------
          that, before deduction of operating expenses, approximate the price
          and yield performance of U.S. Government, mortgage-backed, asset-
          backed and corporate debt securities as represented by the Lehman
          Brothers Aggregate Bond Index. This investment objective is not
          fundamental and may be changed by Mercantile's Board of Directors
          without shareholder approval.

     (b)  Firstar Aggregate Bond Fund:  Seeks to provide an annual rate of total
          ---------------------------
          return, before Fund expenses, comparable to the annual rate of total
          return of the Lehman Brothers Aggregate Bond Index. This investment
          objective is not fundamental and may be changed by Firstar's Board of
          Directors without shareholder approval.

     Comment:  As previously noted, both the Mercantile Bond Index Portfolio and
the Mercantile Government & Corporate Bond Portfolio will reorganize into the
Firstar Aggregate Bond Fund, which has substantially the same investment
objective, policies and restrictions as the Mercantile Government & Corporate
Bond Portfolio.

     The Mercantile Bond Index Portfolio is not managed through the use of
traditional methods of investment management, but instead uses an "indexing"
strategy through the use of computer models to approximate, within a 0.95
correlation coefficient, the investment performance of the Lehman Brothers
Aggregate Bond Index (the "Lehman Aggregate"). The Portfolio will invest
substantially all (but not less than 80%) of its total assets in securities
listed in the Lehman Aggregate. The Lehman Aggregate is comprised of U.S.
Government, mortgage-backed, asset-backed and non-convertible corporate debt
securities. The Portfolio's average weighted maturity is not expected to exceed
9 years.

                                      -7-
<PAGE>

     The securities in which the Firstar Aggregate Bond Fund invests are
substantially similar to those in which the Mercantile Bond Index Portfolio
invests.  However, unlike the Mercantile Bond Index Portfolio, the Firstar
Aggregate Bond Fund is managed through the use of traditional methods of
investment management, such as market, economic and security analysis.  The
Fund's average weighted maturity will vary from time to time depending on
current market and economic conditions and FIRMCO's assessment of probable
changes in interest rates.

     While the Mercantile Bond Index Portfolio and the Firstar Aggregate
Bond Fund generally invest in a similar pool of investments, there are some
differences.  Unlike the Mercantile Bond Index Portfolio, the Firstar Aggregate
Bond Fund may invest in collateralized mortgage obligations, convertible
securities and up to 10% of its total assets in U.S. dollar-denominated debt
obligations of foreign issuers, either directly or through American Depository
Receipts ("ADRs") and European Depository Receipts ("EDRs").  Unlike the Firstar
Aggregate Bond Fund, the Mercantile Bond Index Portfolio may invest in index-
based depository receipts.  Both Funds may invest in options, futures and
options on futures.

     Both the Mercantile Bond Index Portfolio and the Firstar Aggregate Bond
Fund will purchase only investment grade debt obligations (i.e., those rated Baa
or higher by Moody's or BBB or higher by S&P) or, in the case of the Firstar
Aggregate Bond Fund only, unrated debt obligations determined to be of
comparable quality. Unlike the Mercantile Bond Index Portfolio, the Firstar
Aggregate Bond Fund normally invests at least 65% of its total assets in debt
obligations rated in one of the top three rating categories (i.e., A or higher
by Moody's or S&P) or unrated debt obligations determined to be of comparable
quality.

6.   MERCANTILE SHORT-INTERMEDIATE MUNICIPAL PORTFOLIO/FIRSTAR TAX-EXEMPT
     INTERMEDIATE BOND FUND

     Investment Objectives:

     (a)  Mercantile Short-Intermediate Municipal Portfolio:  Seeks as high a
          -------------------------------------------------
          level of current income, exempt from regular federal income tax, as is
          consistent with preservation of capital. This investment objective is
          fundamental and may not be changed without the approval of the
          Portfolio's shareholders.

     (b)  Firstar Tax-Exempt Intermediate Bond Fund:  Seeks to provide current
          -----------------------------------------
          income that is substantially exempt from federal income tax and
          emphasize total return with relatively low volatility of principal.
          This investment objective is not fundamental and may be changed by
          Firstar's Board of Directors without shareholder approval.

     Comment:  The Mercantile Short-Intermediate Municipal Portfolio normally
invests (as a matter of fundamental policy which cannot be changed without
shareholder approval) at least 80% of its total assets in municipal securities
issued by state and local governments that pay interest which is exempt from
federal income tax. Investments by the Mercantile Short-Intermediate Municipal
Portfolio in private activity bonds, the interest on which may be subject to the
federal alternative minimum tax, will not be treated as investments in municipal
securities

                                      -8-
<PAGE>

for purposes of the 80% requirement stated above and, under normal conditions,
will not exceed 20% of the Portfolio's total assets when added with any taxable
investments. The Portfolio's average weighted maturity will generally be between
2 and 5 years.

     The Firstar Tax-Exempt Intermediate Bond Fund invests principally in
intermediate-term municipal obligations issued by state and local governments
exempt from federal income tax.  The Fund will normally invest (as a matter of
fundamental policy which cannot be changed without shareholder approval) at
least 80% of its net assets in securities the interest on which is exempt from
regular federal income and alternative minimum taxes and will invest at least
65% of its total assets in bonds and debentures.  The Fund intends to maintain
an average weighted maturity between 3 and 10 years.

     The Mercantile Short-Intermediate Municipal Portfolio, but not the Firstar
Tax-Exempt Intermediate Bond Fund, may invest in tax-exempt derivatives, such as
tender option bonds, participations, beneficial interests in a trust or
partnership interests.  The Firstar Tax-Exempt Intermediate Bond Fund, but not
the Mercantile Short-Intermediate Municipal Portfolio, may invest in municipal
leases, reverse repurchase agreements and options and futures, although the Fund
does not intend to invest in options or futures during the current fiscal year
other than put options on municipal securities.  The Mercantile Short-
Intermediate Municipal Portfolio, like the Firstar Tax-Exempt Intermediate Bond
Fund, may invest in the securities of other investment companies, limited (i)
with respect to the Mercantile Short-Intermediate Municipal Portfolio to the
securities of "money market" funds which invest in the same types of securities
in which the Portfolio is permitted to invest, and (ii) with respect to the
Firstar Tax-Exempt intermediate Bond Fund to the securities of other investment
companies that invest in high quality short-term debt instruments.  The
Mercantile Short-Intermediate Municipal Portfolio may lend its portfolio
securities in an amount not to exceed 33-1/3% of the value of its total assets.
The Firstar Tax-Exempt Intermediate Bond Fund may lend its portfolio securities
in an amount not to exceed 30% of the value of its total assets, although it
does not intend to engage in securities lending during the current fiscal year.

     Both the Firstar Tax-Exempt Intermediate Bond Fund and the Mercantile
Short-Intermediate Municipal Portfolio only may purchase investment grade
municipal securities (i.e., those rated BBB or higher by S&P or Baa or higher by
Moody's) or unrated debt obligations determined to be of comparable quality.
Short-term municipal securities, such as municipal notes and tax-exempt
commercial paper, must have the highest rating assigned by a nationally
recognized rating agency for such instruments if purchased by the Firstar Tax-
Exempt Intermediate Bond Fund or one of the two highest ratings assigned by a
nationally recognized rating agency for such instruments if purchased by the
Mercantile Short-Intermediate Municipal Portfolio.

7.   MERCANTILE BALANCED PORTFOLIO/FIRSTAR BALANCED GROWTH FUND

     Investment Objectives:

     (a)  Mercantile Balanced Portfolio:  Seeks to maximize total return through
          -----------------------------
          a combination of growth of capital and current income consistent with
          the preservation of capital. This investment objective is fundamental
          and may not be changed without the approval of the Portfolio's
          shareholders.

     (b)  Firstar Balanced Growth Fund:  Seeks to achieve a balance of capital
          ----------------------------
          appreciation and current income with relatively low volatility of
          capital. This investment objective is not fundamental and may be
          changed by the Firstar Board of Directors without shareholder
          approval.

     Comment:  The Mercantile Balanced Portfolio invests in a combination of
equity securities, fixed-income securities and money market instruments in
weightings that FIRMCO, through the use of its own dynamic computer models,
believes will offer attractive total returns over time. The Fund normally
invests at least 25% of its total assets in fixed-income securities and no more
than 75% of its total assets in equity securities, although the actual
percentages will vary from time to time based on FIRMCO's economic and market
outlooks. The Portfolio's equity securities consist mainly of common stocks of
companies with large market capitalizations and its fixed-income securities
consist mainly of investment grade bonds (i.e., those rated in one of the top
four rating categories by one or more nationally recognized rating agencies or
unrated bonds determined to be of comparable quality), including U.S. Government
securities.

     The Firstar Balanced Growth Fund invests principally in a diversified
portfolio of fixed-income and equity securities. Although the actual percentages
will vary from time to time based on FIRMCO's economic and market outlooks, the
Fund's policy is to invest at least 25% of its total assets in fixed-income
senior securities and at least 50% and no more than 65% of its total assets in
equity securities at all times. The Fund's equity securities are selected on the
basis of their potential capital appreciation and consist mainly of common stock
of domestic and foreign companies. These equity securities generally have market
capitalizations between $100 million and $100 billion, although from time to
time a portion of the Fund's assets may be invested in securities with larger or
smaller market capitalizations. The fixed-income securities selected for the
Fund are those which FIRMCO believes will provide an annual rate of total return
similar to that of the Lehman Brothers Government/Corporate Bond Fund. Except
for convertible securities, the Fund will purchase only fixed-income securities
rated investment grade or unrated obligations determined to be of comparable
quality.

     Both the Mercantile Balanced Portfolio and the Firstar Balanced Growth Fund
may invest in preferred stock, rights, warrants and securities convertible into
common stock. The Firstar Balanced Growth Fund may invest no more than 5% of its
net assets in rights and both the Firstar Balanced Growth Fund and Mercantile
Balanced Portfolio may invest no more than 5% of their net assets in warrants.
In addition, the Mercantile Balanced Portfolio may invest no more than

                                      -10-
<PAGE>

2% of its net assets in warrants that are not listed on the New York, American
or Canadian Stock Exchanges. The Firstar Balanced Growth Fund, unlike the
Mercantile Balanced Portfolio, may invest up to 5% of its net assets in
convertible securities rated below investment grade. The Mercantile Balanced
Portfolio may invest in foreign securities indirectly through ADRs and EDRs. The
Firstar Balanced Growth may invest in foreign securities directly and indirectly
through ADRs.

     While both the Mercantile Balanced Portfolio and the Firstar Balanced
Growth Fund may invest in securities issued by other investment companies, the
Mercantile Balanced Portfolio limits such investments to those securities issued
by "money market" funds which invest in securities in which the Fund may invest.
The Firstar Balanced Growth Fund may invest in securities of other investment
companies that invest in high-quality, short-term debt instruments. The
Mercantile Balanced Portfolio, unlike the Firstar Balanced Growth Fund, may
invest in Standard & Poor's Depository Receipts, Standard & Poor's MidCap 400
Depository Receipts and the Dow Industrial DIAMONDS.

     The Mercantile Balanced Portfolio may purchase put and call options on
particular securities or securities indices for hedging purposes in an amount
not to exceed 10% of its net assets.  The Firstar Balanced Growth Fund may
purchase put and call options on particular securities or securities indices to
manage exposure to certain markets, enhance income or for hedging purposes in an
amount not to exceed 5% of its net assets.  Further the Mercantile Balanced
Portfolio and the Firstar Balanced Growth Fund each may write covered call
options in an amount not to exceed 25% of its net assets.  The Mercantile
Balanced Portfolio may lend its portfolio securities in an amount not to exceed
33-1/3% of the value of its total assets, while the Firstar Balanced Growth Fund
may lend its portfolio securities in an amount not to exceed 30% of the value of
its total assets.

8.   MERCANTILE EQUITY INDEX PORTFOLIO/FIRSTAR EQUITY INDEX FUND

     Investment Objectives:

     (a)  Mercantile Equity Index Portfolio:  Seeks to provide investment
          ---------------------------------
          results that, before the deduction of operating expenses, approximate
          the price and yield performance of U.S. publicly traded common stocks
          with large stock market capitalizations, as represented by the
          Standard & Poor's 500 Index. This investment objective is not
          fundamental and may be changed by the Mercantile Board of Directors
          without shareholder approval.

     (b)  Firstar Equity Index Fund:  Seeks returns, before Fund expenses,
          comparable to the price and yield performance of publicly traded
          common stocks in the aggregate, as represented by the Standard &
          Poor's 500 Index. This investment objective is not fundamental and may
          be changed by the Firstar Board of Directors without shareholder
          approval.

                                      -11-
<PAGE>

     Comment:  The Mercantile Equity Index Portfolio and the Firstar Equity
Index Fund are not managed through the use of traditional methods of investment
management, but instead use an "indexing" strategy through the use of computer
models to approximate the investment performance of the Standard & Poor's 500
Index (the S&P 500").  Both Funds invest substantially all of their assets (at
least 80%) in securities included in the S&P 500 and typically hold all 500
stocks represented in the S&P 500.  It is expected that the quarterly
performance of the Firstar Equity Index Fund and the S&P 500 Index normally will
be within  0.3%.  The quarterly performance of the Mercantile Equity Index
Portfolio, before expenses, normally tracks the performance of the S&P 500 Index
within a .95 correlation coefficient.  Both the Mercantile Equity Index
Portfolio and the Firstar Equity Index Fund include stocks in their respective
portfolios based on such stocks' market capitalization weightings in the S&P 500
Index.  Unlike the Firstar Equity Fund, the Mercantile Equity Index Portfolio
may invest in index-based depository receipts, such as Standard & Poor's
Depository Receipts, in lieu of investment in the actual securities listed in
the S&P 500, as well as in rights, warrants and convertible securities.

     The Mercantile Equity Index Portfolio may purchase put and call options on
particular securities or securities indices for hedging purposes in an amount
not to exceed 10% of its net assets. The Firstar Equity Index Fund may purchase
put and call options on securities indices, but not on particular securities, to
manage exposure to certain markets, enhance income or for hedging purposes in an
amount not to exceed 5% of its net assets. The Mercantile Equity Index Portfolio
may write covered call options on particular securities and indices in the
amount not to exceed 25% of its net assets, while covered call options written
by the Firstar Equity Index Fund are limited to options on securities indices
and may not exceed 5% of the Fund's net assets. Both the Mercantile Equity Index
Portfolio and the Firstar Equity Index Fund may enter into futures contracts and
related options, although the Firstar Equity Index Fund will limit its
transactions in futures contracts and related options so that not more than 10%
of its net assets are at risk.

     While both the Mercantile Equity Index Portfolio and the Firstar Equity
Index Fund may invest in securities issued by other investment companies, the
Mercantile Equity Index Portfolio limits such investments to those securities
issued by "money market" funds which invest in securities in which the Fund may
invest. The Firstar Equity Index Fund may invest in securities of other
investment companies that invest in high-quality, short-term debt instruments.
The Mercantile Equity Index Portfolio may lend its portfolio securities in an
amount not to exceed 33-1/3% of the value of its total assets, while the Firstar
Equity Index Fund may lend its portfolio securities in an amount not to exceed
30% of the value of its total assets.

9.   MERCANTILE GROWTH & INCOME EQUITY PORTFOLIO/FIRSTAR GROWTH INCOME FUND

     Investment Objectives:

     (a)  Mercantile Growth & Income Equity Portfolio:  Seeks to provide long-
          term capital growth, with income a secondary consideration. This
          investment objective is fundamental and may not be changed without the
          approval of the Portfolio's shareholders.

                                      -12-
<PAGE>

     (b)  Firstar Growth & Income Fund:  Seeks both reasonable income and long-
          ----------------------------
          term capital appreciation. This investment objective is not
          fundamental and may be changed by the Firstar Board of Directors
          without shareholder approval.

     Comment:  The Mercantile Growth & Income Equity Portfolio invests primarily
in common stocks. These stocks are generally listed on a national stock exchange
or are unlisted securities with an established over-the-counter market. Stocks
of companies which are believed to have superior revenue and earnings growth
prospects relative to their peers and to their price/earnings ratios are
favored. Income is not a major factor in the stock selection process. The
Portfolio may also invest in preferred stock, rights, warrants and convertible
securities. The Portfolio may invest up to 15% of its total assets in foreign
securities directly or indirectly through ADRs and EDRs.

     The Firstar Growth & Income Fund selects common stocks primarily from a
universe of domestic companies that have established dividend-paying histories.
Normally, at least 50% of the Fund's net assets will be invested in equities.
The Fund will not purchase a non-dividend paying security if immediately after
giving effect to such purchase less than 80% of the net assets of the Fund will
be invested in dividend paying securities.  The Fund generally invests in
medium-to-large sized companies with stock market capitalizations over $1
billion although, the Fund may also invest a portion of its assets in companies
with smaller market capitalizations.  Although the Fund invests primarily in
common stocks, it may also invest in preferred stock, rights, warrants and
convertible securities, although the Fund will invest in preferred stocks only
if they present an opportunity for capital appreciation and in preferred stocks
convertible into common stocks only if they provide a current dividend payment.
The Fund also may invest in bonds, notes and debentures if these investments
provide a current interest payment and may purchase non-convertible debt
securities if they present an opportunity for capital appreciation.  The Fund
may also invest in foreign securities directly or indirectly through ADRs.

     The Mercantile Growth & Income Equity Portfolio may purchase put and call
options on particular securities or securities indices for hedging purposes in
an amount not to exceed 10% of its net assets. The Firstar Growth & Income Fund
may purchase put and call options on particular securities or securities indices
to manage exposure to certain markets, enhance income or for hedging purposes in
an amount not to exceed 5% of its net assets. The Mercantile Growth & Income
Equity Portfolio may write covered call options in an amount not to exceed 25%
of its net assets, while covered call options written by the Firstar Growth &
Income Fund may not exceed 5% of the Fund's net assets. Both the Mercantile
Growth & Income Equity Portfolio and the Firstar Growth & Income Fund may enter
into futures contracts and related options, although the Firstar Growth & Income
Fund intends to limit its investment in futures contracts and related options so
that not more than 5% of its net assets are at risk. The Firstar Growth and
Income Fund, unlike the Mercantile Growth Income Portfolio, may buy and sell
futures contracts and related options on foreign exchanges or boards of trade.

     While both the Mercantile Growth & Income Equity Portfolio and the Firstar
Growth & Income Fund may invest in securities issued by other investment
companies, the Mercantile Growth & Income Equity Portfolio limits such
investments to those securities issued by "money market" funds which invest in
securities in which the Fund may invest. The Firstar Growth &

                                      -13-
<PAGE>

Income Fund may invest in securities of other investment companies that invest
in high-quality, short-term debt instruments. The Mercantile Growth & Income
Equity Portfolio, unlike the Firstar Growth & Income Fund, may invest in
Standard & Poor's Depository Receipts, Standard & Poor's MidCap 400 Depository
Receipts and The Dow Industrials DIAMONDS.

     The Mercantile Growth & Income Equity Portfolio may lend its portfolio
securities in an amount not to exceed 33 1/3% of the value of its total assets,
while Firstar Growth & Income Fund may lend its portfolio securities in an
amount not to exceed 30% of the value of its total assets.

10.  MERCANTILE GROWTH EQUITY PORTFOLIO/FIRSTAR GROWTH FUND

     Investment Objectives:

     (a)  Mercantile Growth Equity Portfolio:  Seeks capital appreciation.  This
          ----------------------------------
          investment objective is fundamental and may not be changed without the
          approval of the Portfolio's shareholders.

     (b)  Firstar Growth Fund:  Seeks capital appreciation through investment in
          -------------------
          securities of large-sized companies. This investment objective is not
          fundamental and may be changed by the Firstar Board of Directors
          without shareholder approval.

     Comment: It is expected that at the time of the Reorganization, the Firstar
Growth Fund will be renamed the Firstar Large Cap Core Equity Fund.

     The Mercantile Growth Equity Portfolio normally invests at least 65% of its
total assets in stocks or other equity securities of large- and medium-
capitalization companies that are listed on the New York Stock Exchange, the
American Stock Exchange or NASDAQ. The Portfolio invests primarily in the common
stocks of growth companies.

     The Firstar Growth Fund normally invests at least 50% of its total assets
in equity securities. Most of these equity securities are publicly traded common
stocks of companies incorporated in the U.S. The Fund generally invests in
large-sized companies with stock market capitalizations over $3 billion that are
considered to be well-managed and to have attractive fundamental financial
characteristics (such as low debt, high returns on equity and consistent revenue
and earnings per share growth over the prior three to five years). The Fund may
also invest a portion of its assets in companies with market capitalizations
below $3 billion.

     While both the Mercantile Growth Equity Portfolio and the Firstar Growth
Fund may invest in preferred stock, rights warrants and convertible securities,
the Firstar Growth Fund may invest in preferred stocks (including preferred
stocks convertible into common stock) only if they present an opportunity for
capital appreciation. The Mercantile Growth Equity Portfolio, like the Firstar
Growth Fund, may invest up to 5% of its net assets in warrants, although the
Mercantile Growth Equity Portfolio limits its investment in warrants which are
not listed on the New York or American Stock Exchanges to no more than 2% of its
net assets. Both the Mercantile Growth Equity Portfolio and the Firstar Growth
Fund may invest a portion of their assets in investment

                                      -14-
<PAGE>

grade bonds, notes and debentures, although the Firstar Growth Fund will invest
in these securities if they present opportunities for capital appreciation.

     While both the Mercantile Growth Equity Portfolio and the Firstar Growth
Fund may invest in foreign securities, the Mercantile Growth Equity Portfolio
may only do so indirectly by purchasing securities which are traded on U.S.
securities exchanges or in over-the-counter markets in the form of depository
receipts, such as ADRs, in an amount not to exceed 5% of its net assets.

     The Mercantile Growth Equity Portfolio may purchase put options for hedging
purposes and may write covered call options, in each instance only with respect
to individual securities. Not more than 5% of the value of the Mercantile Growth
Equity Portfolio's total assets may be invested in premiums on open put option
positions and the aggregate value of the securities subject to covered call
options written by the Fund may not exceed 25% of the value of its net assets.
The Firstar Growth Fund may purchase put and call options on particular
securities or securities indices to manage exposure to certain markets, enhance
income or for hedging purposes in an amount not to exceed 5% of its net assets.
The Firstar Growth Fund also may write covered call options on particular
securities or securities indices. Both the Mercantile Growth Equity Portfolio
and the Firstar Growth Fund may invest in futures contracts and related options.
Unlike the Mercantile Growth Equity Portfolio, the Firstar Growth Fund may buy
and sell futures contracts and related options on foreign exchanges or boards of
trade.

     Both the Mercantile Growth Equity Portfolio and the Firstar Growth Fund may
invest in securities issued by other investment companies, including in the case
of the Mercantile Growth Equity Portfolio, closed-end investment companies. The
Firstar Growth Fund limits its investments in other investment companies to
those that invest in high-quality, short-term debt instruments. The Mercantile
Growth Equity Portfolio, unlike the Firstar Growth Fund, may invest in Standard
& Poor's Depository Receipts, Standard & Poor's MidCap 400 Depository Receipts
and The Dow Industrials DIAMONDS.

     The Mercantile Growth Equity Portfolio may borrow money directly or
indirectly through reverse repurchase agreements for temporary purposes in an
amount up to 33-1/3% of its total assets, although the Fund intends to limit
such borrowings during the current year to not more than 5% of its net assets.
The Firstar Growth Fund may borrow from banks and enter into reverse repurchase
agreements for temporary purposes in an amount not to exceed 10% of its total
assets. The Mercantile Growth Equity Portfolio may lend its portfolio securities
in an amount not to exceed 33-1/3% of the value of its total assets, while the
Firstar Growth Fund may lend its portfolio securities in an amount not to exceed
30% of the value of its total assets.

11.  MERCANTILE SMALL CAP EQUITY PORTFOLIO/FIRSTAR EMERGING GROWTH FUND

     Investment Objectives:

     (a)  Mercantile Small Cap Equity Portfolio: Seeks capital appreciation.
          -------------------------------------
          This investment objective is fundamental and may not be changed
          without the approval of the Portfolio's shareholders.

     (b)  Firstar Emerging Growth Fund: Seeks capital appreciation. This
          ----------------------------
          investment objective is not fundamental and may be changed by the
          Firstar Board of Directors without shareholder approval.

     Comment: It is expected that at the time of the Reorganization, the Firstar
Emerging Growth Fund will be renamed the Firstar Small Cap Core Equity Fund.

     It is also expected that at the time of the Reorganization the Firstar
Emerging Growth Fund will adopt an investment objective and certain non-
fundamental investment policies and restrictions that are substantially the same
as those of the Mercantile Small Cap Equity Portfolio.

     The Mercantile Small Cap Equity Portfolio normally invests at least 65% of
its total assets in the stocks of small- to medium-sized companies with market
capitalizations from $100 million to $2 billion at the time of purchase and
which are believed to have above-average prospects for capital appreciation.
These stocks may be listed on a national securities exchange or may be unlisted
securities with or without an established over-the-counter-market.  The
Portfolio may also invest in larger companies that offer growth possibilities
and to a limited extent in initial public offerings.  In addition to common
stock, the Portfolio may also invest in preferred stock, rights, warrants and
convertible securities.  The Portfolio will not invest more than 5% of its net
assets in warrants and will limit its investments in warrants which are not
listed on the New York, American or Canadian Stock Exchange to not more than 2%
of net assets.  The Portfolio may invest up to 25% of its total assets in
foreign securities indirectly through ADRs and EDRs.  The Portfolio does not
intend to invest more than 5% of its total assets in the securities of
unseasoned companies (i.e. those which, with any predecessors, have less than 3
years of continuous operations).

     The Firstar Emerging Growth Fund selects securities based on their
potential for price appreciation. Normally, the Fund invests at least 50% of its
total assets in equity securities. Most of these equity securities will be
publicly traded common stocks of small-sized companies incorporated in the U.S.
with market capitalizations between $250 million and $2 billion. The Fund may
also invest in investment grade non-convertible bonds, notes, debentures and
convertible preferred stock and may invest up to 5% of its net assets in rights
and warrants. The Fund may also invest in foreign securities directly or
indirectly through ADRs.

     The Mercantile Small Cap Equity Portfolio may purchase  put and call
options on particular securities or securities indices for hedging purposes in
an amount not to exceed 10% of its net assets.  The Firstar Emerging Growth Fund
may purchase put and call options on

                                      -16-
<PAGE>

particular securities or securities indices to manage exposure to certain
markets, enhance income or for hedging purposes in an amount not to exceed 5% of
its net assets. The Mercantile Small Cap Equity Portfolio may write covered call
options in an amount not to exceed 25% of its net assets while covered call
options written by the Firstar Emerging Growth Fund will not exceed 5% of the
Fund's net assets.

     While both the Mercantile Small Cap Equity Portfolio and the Firstar
Emerging Growth Fund may invest in securities issued by other investment
companies, the Mercantile Small Cap Equity Portfolio limits such investments to
those securities issued by "money market" funds which invest in securities in
which the Fund may invest.  The Firstar Emerging Growth Fund may invest in
securities of other investment companies that invest in high-quality, short-term
debt instruments.

     The Mercantile Small Cap Equity Portfolio may lend its portfolio securities
in an amount not to exceed 33-1/3% of the value of its total assets while the
Firstar Emerging Growth Fund may lend its portfolio securities in an amount not
to exceed 30% of the value of its total assets.

12.  MERCANTILE INTERNATIONAL EQUITY PORTFOLIO/FIRSTAR CORE INTERNATIONAL EQUITY
     FUND

     Investment Objectives:

     (a)  Mercantile International Equity Portfolio: Seeks to provide capital
          -----------------------------------------
          growth consistent with reasonable investment risk. This investment
          objective is fundamental and may not be changed without the approval
          of the Portfolio's shareholders.

     (b)  Firstar Core International Equity Fund: Seeks to provide maximum,
          --------------------------------------
          long-term total return consistent with reasonable risk of principal.
          This investment objective is not fundamental and may be changed by the
          Firstar Board of Directors without shareholder approval.

     Comment: It is expected that at the time of the Reorganization, the Firstar
Core International Equity Fund will be renamed the Firstar International Growth
Fund.

     It is also expected that at the time of the Reorganization the Firstar Core
International Equity Fund will adopt an investment objective and certain non-
fundamental investment policies and restrictions that are substantially the same
as those of the Mercantile International Equity Portfolio.

     The Mercantile International Equity Portfolio invests primarily in foreign
common stocks, most of which are denominated in foreign currencies.  The
Portfolio normally invests at least 80% of its total assets in securities of
companies that derive more than 50% of their gross revenues outside the United
States or have more than 50% of their assets invested outside the United States.
The Portfolio normally invests in equity securities from at least three
different foreign countries.  Generally, at least 50% of the Portfolio's total
assets will be invested in the

                                      -17-
<PAGE>

securities of companies located in the developed countries of Western Europe and
Japan, although the Fund may also invest in other developed countries in the Far
East and in countries with emerging markets or economies.

     The Firstar Core International Equity Fund invests primarily in common
stocks and other equity securities of companies located outside the United
States. Normally, at least 65% of its total assets will be invested in
securities, such as equity securities, securities convertible into equity
securities and debt, of companies based in at least three different countries
other than the United States.

     Both the Mercantile International Equity Portfolio and the Firstar Core
International Equity Fund may invest in preferred stock, but only the Mercantile
International Equity Portfolio may invest in rights, warrants and convertible
securities. The Mercantile International Equity Portfolio will not invest more
than 5% of its net assets in warrants and will limit its investments in warrants
not listed on the New York, American or Canadian Stock Exchange to not more than
2% of net assets. Unlike the Firstar Core International Equity Fund, the
Mercantile International Equity Portfolio may purchase index-based depository
receipts, including Standard & Poor's Depository Receipts, Standard & Poor's
MidCap 400 Depository Receipts and The Dow Industrial's DIAMONDS. Both the
Mercantile International Equity Portfolio and the Firstar Core International
Equity Fund may invest in foreign securities indirectly through ADRs and EDRs,
but only the Firstar Core International Equity Fund may invest in Global
Depository Receipts ("GDRs"). While both Funds are permitted to invest up to 15%
of their net assets in illiquid securities, the Mercantile International Equity
Portfolio limits its investment in restricted securities to 10% of net assets.
The Mercantile International Equity Portfolio, unlike the Firstar Core
International Equity Fund, does not invest in the securities of small or
unseasoned companies with less than three years of continuous operation.

     Unlike the Firstar Core International Equity Fund which may not engage in
options transactions, the Mercantile International Equity Portfolio may purchase
put and call options on particular securities or securities indices for hedging
(or cross-hedging) purposes or for the purpose of earning additional income in
an amount not exceeding 10% of the Portfolio's net assets. The Mercantile
International Equity Portfolio also may write covered call options in an amount
not to exceed 25% of its net assets and may purchase foreign currency put and
call options, unlisted currency options and write foreign currency call options.
The Mercantile International Equity Portfolio may invest in interest rate
futures contracts, options on futures contracts and other types of financial
futures contracts, such as foreign currency contracts, as well as any index or
foreign market futures which are available in recognized exchanges or in other
established financial markets. The Firstar Core International Equity Fund's
investments in futures are limited to forward foreign currency contracts and
currency futures.

     While both the Mercantile International Equity Portfolio and the Firstar
Core International Equity Fund may invest in securities issued by other
investment companies, the Mercantile International Equity Portfolio limits such
investments to those securities issued by "money market" funds which invest in
securities in which the Fund may invest.  The Firstar Core International Equity
Fund may invest in securities of other investment companies that invest in high-
quality, short-term debt instruments.

     The Mercantile International Equity Portfolio may lend its portfolio
securities in an amount not to exceed 33-1/3% of the value of its total assets
while the Firstar Core International Equity Fund may lend its portfolio
securities in an amount not to exceed 30% of the value of its total assets.

                                   EXHIBIT A

                         Firstar Stellar Treasury Fund

Investment Objective
--------------------

The Fund seeks to achieve stability of principal and current income consistent
with stability of principal.  The investment objective is fundamental and cannot
be changed without the approval of shareholders.

Principal Investment Strategies
-------------------------------

The Fund intends to achieve its investment goal by investing exclusively in
short-term U.S. Treasury obligations that have a maturity of 397 days or less
from the date of purchase.  The Fund may purchase repurchase agreements
collateralized by U.S. Treasury obligations.  The Fund intends to invest in
agreements that provide for repurchase within 397 days from the date of
acquisition.  The average maturity of these securities is 120 days or less.  The
average maturity, however, of all the securities in the Fund's portfolio will be
90 days or less on a dollar-weighted basis.  Securities subject to repurchase
agreements are marked to market on a daily basis.  U.S. Treasury obligations are
issued by the U.S. government and are fully guaranteed as to principal and
interest by the United States government.  The Fund may also retain assets in
cash and may purchase U.S. Treasury obligations on a when-issued or delayed
delivery basis.

Principal Risks of Investing in the Fund
----------------------------------------

The main risks of investing in the Fund are:

 .    Interest rate risk: The rate of income will vary from day to day depending
     on short-term interest rates. It is possible that a major change in
     interest rates could cause the value of your investment to decline.

 .    Credit risk: The Fund can also be affected by changes in the credit quality
     rating of a security or changes in an issuer's financial condition. A
     default on a security or a repurchase agreement held by the Fund could
     cause the value of your investment to decline.

 .    Loss of principal: Although the Fund seeks to preserve the value of your
     investment at $1.00 per share, it is possible to lose money by investing in
     the Fund.

 .    Repurchase agreement risk: One of the risks of investing in repurchase
     agreements is that the seller may not repurchase the securities held as
     collateral for the repurchase agreement from the Fund. Another risk of
     repurchase agreements is that the seller may default or file for
     bankruptcy. That could mean that the Fund might have to wait through
     lengthy court actions before selling the securities. See "Additional
     Information About Investment Policies and Risks - Repurchase Agreements"
     below.

                                      A-1
<PAGE>

 .    When-issued and delayed delivery transaction risk: One of the risks of
     investing in when-issued or delayed delivery transactions is that if the
     seller chooses not to complete the transaction, the Fund could miss an
     advantageous price or yield. Another risk is that because settlement dates
     may be a month or more after entering into the transactions, the market
     value of the securities may have dropped from the agreed upon purchase
     price. However, the Fund may cancel a commitment to purchase securities
     prior to settlement if the Fund's investment adviser believes it is
     appropriate. The Fund may enter into transactions to sell its purchase
     commitment to third parties at current market rates and simultaneously
     acquire other commitments to purchase similar securities at later dates.
     The Fund may realize short-term profits or losses on the sale of these
     kinds of commitments. See "Additional Information About Investment Policies
     and Risks - When-Issued and Delayed Delivery Transactions" below.

Additional Information About Investment Policies and Risks
----------------------------------------------------------

This section provides additional information regarding investments and
transactions the Fund is permitted to make. Unless otherwise indicated, the
investment policies of the Fund may be changed by the Trustees without approval
of shareholders. Shareholders will be notified before any material change in
these policies becomes effective.

The Fund may follow non-fundamental operational policies that are more
restrictive than the fundamental investment limitations set forth in this
Exhibit in order to comply with applicable laws and regulations, including the
provisions of and regulations under the Investment Company Act of 1940. In
particular, the Fund will comply with the various requirements of Rule 2a-7,
which regulates money market mutual funds. The Fund will also determine the
effective maturity of its investments, as well as its ability to consider a
security as having received the requisite short-term ratings by a nationally
recognized statistical rating organization according to Rule 2a-7.  The Fund may
change these operational policies to reflect changes in the laws and regulations
without the approval of shareholders.

Repurchase Agreements
---------------------

The Fund may invest in repurchase agreements which are arrangements with banks,
broker/dealers, and other recognized financial institutions to sell securities
to the Fund and agree to repurchase them at a mutually agreed upon time and
price within one year from the date of acquisition. The Fund or its custodian
will take possession of the securities subject to repurchase agreements, and
these securities will be marked to market daily. To the extent that the original
seller does not repurchase the securities from the Fund, the Fund could receive
less than the repurchase price on any sale of such securities. In the event that
such a defaulting seller filed for bankruptcy or became insolvent, disposition
of such securities by the Fund might be delayed pending court action. The Fund
believes that under the regular procedures normally in effect for custody of the
Fund's portfolio securities subject to repurchase agreements, a court of
competent jurisdiction would rule in favor of the Fund and allow retention or
disposition of such securities.  The Fund will only enter into repurchase
agreements with banks and other recognized financial institutions, such as
broker/dealers, which are deemed by the Fund's adviser to be creditworthy
pursuant to guidelines established by the Board of Trustees.

                                      A-2
<PAGE>

When-Issued and Delayed Delivery Transactions
---------------------------------------------

The Fund may purchase short-term obligations on a when-issued or delayed
delivery basis. These transactions are arrangements in which the Fund purchases
securities with payment and delivery scheduled for a future time. The seller's
failure to complete these transactions may cause the Fund to miss a price or
yield considered advantageous. Settlement dates may be a month or more after
entering into these transactions and the market values of the securities
purchased may vary from the purchase prices.

The Fund may dispose of a commitment prior to settlement if the investment
adviser deems it appropriate to do so. In addition, the Fund may enter into
transactions to sell its purchase commitments to third parties at current market
values and simultaneously acquire other commitments to purchase similar
securities at later dates.  The Fund may realize short-term profits or losses
upon the sale of such commitments.

These transactions are made to secure what is considered to be an advantageous
price or yield for the Fund. No fees or other expenses, other than normal
transaction costs, are incurred. However, liquid assets of the Fund sufficient
to make payment for the securities to be purchased are segregated on the Fund's
records at the trade date. These assets are marked to market daily and are
maintained until the transaction is settled.  The Fund does not intend to engage
in when-issued and delayed delivery transactions to an extent that would cause
the segregation of more than 20% of the total value of its assets.

Restricted and Illiquid Securities
----------------------------------

The Fund may invest in a limited amount of restricted securities. Restricted
securities are securities that are thinly traded or whose resale is restricted
by federal securities laws. Restricted securities are any securities in which
the Fund may invest pursuant to its investment objective and policies but which
are subject to restrictions on resale under federal securities laws. The Fund's
Board of Trustees has established criteria that allows the adviser to consider
certain restricted securities as liquid.

The adviser may consider the following criteria in determining the liquidity of
certain restricted securities: (a) the frequency of trades and quotes for the
security; (b) the number of dealers willing to purchase or sell the security and
the number of other potential buyers; (c) dealer undertakings to make a market
in the security; and (d) the nature of the security and the nature of the
marketplace trades.

                                      A-3
<PAGE>

Other Investment Companies
--------------------------

As an efficient means of carrying out its investment policies, the Fund may
invest in the securities of other investment companies.  A disadvantage to
investing in other investment  companies is that they also carry certain
expenses such as management fees. As a result, any investment by the Fund in
shares of other investment companies may duplicate shareholder expenses.

Reverse Repurchase Agreements
-----------------------------

The Fund may enter into reverse repurchase agreements. This transaction is
similar to borrowing cash.  In a reverse repurchase agreement, the Fund
transfers possession of a portfolio instrument to another person, such as a
financial institution, broker, or dealer, in return for a percentage of the
instrument's market value in cash and agrees that on a stipulated date in the
future the Fund will repurchase the portfolio instrument by remitting the
original consideration, plus interest at an agreed upon rate.

When effecting reverse repurchase agreements, liquid assets of the Fund, in a
dollar amount sufficient to make payment for the obligations to be purchased,
are segregated at the trade date. These securities are marked to market daily
and are maintained until the transaction is settled. During the period any
reverse repurchase agreements are outstanding, the Fund will restrict the
purchase of portfolio instruments to money market instruments maturing on or
before the expiration date of the reverse repurchase agreements, but only to the
extent necessary to assure completion of the reverse repurchase agreements. The
use of reverse repurchase agreements may enable the Fund to avoid selling
portfolio instruments at a time when a sale may be deemed to be disadvantageous,
but the ability to enter into reverse repurchase agreements does not ensure that
the Fund will be able to avoid selling portfolio instruments at a
disadvantageous time.

The Fund's Investment Limitations
---------------------------------

The following is a list of the Fund's fundamental investment limitations, which
cannot be changed without the approval of a majority of the Fund's outstanding
voting securities.  As used in this Exhibit, "a majority of the Fund's
outstanding voting securities" means the lesser of (a) 67% of the shares of
beneficial interest of the Fund represented at a meeting at which more than 50%
of the outstanding shares are present, or (b) more than 50% of the outstanding
shares of beneficial interest of the Fund.

1.   The Fund will not sell any securities short.

2.   The Fund will not purchase any securities on margin, but it may obtain such
     short-term credits as may be necessary for clearance of purchases and sales
     of portfolio securities.

3.   The Fund will not issue senior securities, except that the Fund may borrow
     money directly or through reverse repurchase agreements in amounts up to
     one-third of the value of its total assets, including the amount borrowed.

                                      A-4
<PAGE>

4.   The Fund will not borrow money or engage in reverse repurchase agreements
     for investment leverage. However, the Fund may borrow money up to one-third
     of the value of its total assets as a temporary, extraordinary, or
     emergency measure or to facilitate management of the Fund by enabling the
     Fund to meet redemption requests when the liquidation of portfolio
     securities is deemed to be inconvenient or disadvantageous. Interest paid
     on borrowed funds will serve to reduce the Fund's income.  The Fund will
     not purchase any securities while borrowings and reverse repurchase
     agreements in excess of 5% of its total assets are outstanding. During the
     period any reverse repurchase agreements are outstanding, the Fund will
     restrict the purchase of portfolio securities to money market instruments
     maturing on or before the expiration date of the reverse repurchase
     agreements, but only to the extent necessary to assure completion of the
     reverse repurchase agreements.

5.   The Fund will not mortgage, pledge, or hypothecate any assets except to
     secure permitted borrowings. In those cases, the Fund may mortgage, pledge,
     or hypothecate assets having a market value not exceeding 10%.

6.   The Fund will not underwrite any issue of securities, except as it may be
     deemed to be an underwriter under the Securities Act of 1933 in connection
     with the sale of securities in accordance with its investment objective,
     policies, and limitations.

7.   The Fund will not purchase or sell real estate, including limited
     partnership interests. However, the Fund may invest in the securities of
     companies whose business involves the purchase or sale of real estate or in
     securities that are secured by real estate or interests in real estate.

8.   The Fund will not purchase or sell commodities, commodity contracts, or
     commodity futures contracts.

9.   The Fund will not lend any of its assets, except that it may purchase or
     hold U.S. Treasury obligations, including repurchase agreements.

The Trustees may change the following investment limitations without shareholder
approval.  Shareholders will be notified before any material change in these
limitations becomes effective.

1.   The Fund will not invest more than 10% of the value of its net assets in
     illiquid securities, including certain restricted securities not determined
     to be liquid under criteria established by the Trustees and repurchase
     agreements providing for settlement in more than seven days after notice.

2.   The Fund will limit its investment in other investment companies to: (a) no
     more than 3% of the total outstanding voting stock of any investment
     company; (b) no more than 5% of its total assets in any one investment
     company; and (c) no more than 10% of its total assets in investment
     companies in general.  The Fund will limit its investments in the
     securities of other investment companies to those of money market funds
     having investment objectives and policies similar to its own.  These
     limitations are not applicable

                                      A-5
<PAGE>

     if the securities are acquired in a merger, consolidation, reorganization
     or acquisition of assets.

Except with respect to borrowing money, if a percentage limitation is adhered to
at the time of investment, a later increase or decrease in percentage resulting
from any change in value or net assets will not result in a violation of such
restriction.

The Fund does not expect to borrow money or pledge securities in excess of 5% of
the value of its total assets in the coming fiscal year.

For purposes of its policies and limitations, the Fund considers certificates of
deposit and demand and time deposits issued by a U.S. branch of a domestic bank
or savings association having capital, surplus, and undivided profits in excess
of $100,000,000 at the time of investment to be "cash items."

The sales charge on Mercantile Investor A Shares and Firstar Retail A Shares may
be reduced through:

1)   Rights of Accumulation
     ----------------------

     a.   Mercantile Investor A Shares
          ----------------------------

          In calculating the appropriate sales charge rate, this right allows
investors to add the value of the Investor A Shares of the non-money market
funds they already own, as well as the value of any existing Retail A or Class A
Shares of any other fund in the Firstar family of funds, to the amount they are
currently purchasing.

     b.   Firstar Retail A Shares
          -----------------------

          In calculating the appropriate sales charge rate, the right allows
investors to add the value of the Retail A Shares of the non-money market fund
they already own, as well as the value of any existing Investor A or Class A
Shares of any other fund in the Firstar family of funds, to the amount they are
currently purchasing.

2)   Letter of Intent
     ----------------

     a.   Mercantile Investor A Shares
          ----------------------------

          An investor can purchase Investor A Shares of any Mercantile Non-Money
Market Fund or Retail A or Class A Shares of any fund in the Firstar family of
funds that charges a sales load over a 13-month period and pay the same sales
charge the investor would have paid if all shares were purchased at once.
Mercantile's transfer agent will hold in escrow 5% of the investor's total
investment (for payment of a higher sales load in case you do not purchase the
full amount indicated on the application) until the full amount is received.

     b.   Firstar Retail A Shares
          -----------------------

          An investor can purchase Retail A Shares of any Firstar Non-Money
Market Fund or Investor A or Class A Shares of any fund in the Firstar family of
funds that charges a sales load over a 13-month period and pay the same sales
charge the investor would have paid if all shares were purchased at once.  The
investor may obtain the reduced sales charge by means of a written Letter of
Intent which expresses a non-binding commitment to invest in the aggregate
$100,000 or more in Firstar Non-Money Market Fund Retail A Shares or Investor A
or Class A Shares of any Firstar family of funds.  The transfer agent will hold
in escrow shares equal to 5% of the amount indicated in the Letter of Intent for
payment of a higher sales charge if an Investor does not purchase the full
amount indicated in the Letter of Intent.

3)   Quantity Discounts
     ------------------

     a.   Mercantile Investor A Shares
          ----------------------------

          As the dollar amount of an investor's purchase increases, the sales
charge may decrease (see the table above). In addition, Mercantile will combine
purchases made on the same day by the investor and the investor's immediate
family members when calculating applicable sales charge.

     b.   Firstar Retail A Shares
          -----------------------

          As the dollar amount of an investor's purchase increases, their sales
charge may decrease (see the table above).  For purposes of applying the Rights
of Accumulation and Letter of Intent privileges, the sales charge schedule
applies to the combined purchases made by any individual and/or spouse
purchasing securities for his, her or their own account, or the aggregate
investments of a trustee or other fiduciary or IRA for the benefits of the
persons listed below (See "Waivers - Mercantile Investor A Shares and Firstar
Retail A Shares").

4)   Reinvestment Privilege
     ----------------------

     a.   Mercantile Investor A Shares
          ----------------------------

          Mercantile investors can reinvest some or all of the money that they
receive when they sell Investor A Shares of a Mercantile Fund in Investor A
Shares of any other Mercantile Fund or in shares of any other fund in the
Firstar family of funds within 60 days without paying a sales charge.  An
investor must notify Mercantile's transfer agent at the time of reinvestment
that the investor qualifies for this privilege.

     b.   Firstar Retail A Shares
          -----------------------

          If you sell shares of a Firstar Fund or of any Firstar family of
funds, you may reinvest some or all of the process in the Retail A Shares of any
Firstar Fund within 60 days without a sales charge, as long as the investor
notifies the transfer agent or shareholder organization at the time of the
investor's reinvestment.

     More Information about Exchanging Shares
     ----------------------------------------

     Firstar Funds
     -------------

     Generally, any share class of a Firstar Fund is exchangeable for the same
share class of another Firstar Fund, provided you are eligible to purchase that
share class or Fund. Listed below are permitted exchanges between different
share classes of the Funds:

     .    Retail B Shares of a non-money market fund may be exchanged for Retail
          A Shares of a money market fund (except Retail B Shares are not
          exchangeable for any shares of the Institutional Money Market Fund).

     .    Class Y Shares of a non-money market are exchangeable for
          Institutional Shares of a money market fund.

     Unless you qualify for a sales charge exemption, an initial sales charge
will be imposed on the exchange if the shares of the Fund being acquired have an
initial sales charge and the shares being redeemed were purchased without a
sales charge. Retail B Shares acquired in an exchange and Money Market Fund
Shares acquired in an exchange for Retail B Shares will be subject to a
contingent deferred sales charge upon redemption in accordance with this
Prospectus. For purposes of computing the contingent deferred sales charge, the
length of time of ownership will be measured from the date of the original
purchase of Retail B Shares.

     Mercantile Funds
     ----------------

     Trust Shares of one Fund may be exchanged for Trust Shares of another Fund.
Trust II Shares of one money market fund may be exchanged for Trust II Shares of
another money market fund.  An investor may be able to exchange Trust Shares of
one Fund for Investor A Shares of the same Fund if it involves the distribution
of assets from certain types of accounts held at Mercantile Trust Company
National Association or any of its affiliates.  Trust and Trust II Shares may
also be exchanged for shares of corresponding classes of the Firstar Funds and
the Stellar Funds.

     Institutional Shares of one Mercantile Fund may be exchanged for
Institutional Shares of another Mercantile Fund.  Institutional Shares of a
Mercantile Fund may also be exchanged for Class Y Shares of the Firstar Funds
and the Stellar Funds.

     Investor A Shares of one Mercantile Fund may be exchanged for Investor A
Shares of another Mercantile Fund or in certain limited circumstances, Trust or
Institutional Shares.  When exchanging Investor A Shares of a Mercantile Fund
that has no sales charge or a lower sales charge for Investor A Shares of a
Mercantile Fund with a higher sales change, the shareholder will pay the
difference. Investor A Shares may also be exchanged for shares of corresponding
classes of the Firstar Funds and the Stellar Funds.

     Investor B Shares of one Mercantile Fund may be exchanged for Investor B
Shares of another Mercantile Fund without a CDSC on the exchange.  The holding
period of the shares originally held and redeemed will be added to the holding
period of the new shares acquired through the exchange. Investor B Shares may
also be exchanged for shares of corresponding classes of the Firstar Funds and
the Stellar Funds.

E.   Pricing of Shares for each of the Mercantile Funds and Firstar Funds
     --------------------------------------------------------------------

     The price per share (the offering price) will be the net asset value per
share ("NAV") next determined after a Fund receives your purchase order plus, in
the case of Mercantile's Investor A Shares and Firstar Retail A Shares, the
applicable front-end sales charge.

     For processing purchase and redemption orders, the NAVs per share of the
Mercantile Funds and the Firstar Funds are calculated each business day at the
following times:

                           Total Return Performance
                                (As of 7/31/00)

     The total returns of the Firstar Funds are competitive with those of the
Mercantile Funds as shown below. No Y Shares of the Firstar Non-Money Market
Funds or Institutional Shares of the Firstar Money Market Funds were outstanding
as of 7/31/00. In addition, comparisons of the total returns of the Investor A
Shares, Trust Shares and Institutional Shares of the Mercantile Bond Index
Portfolio and Mercantile Government & Corporate Bond Portfolio are set forth
below, since these portfolios are being reorganized into a Firstar Fund that has
not yet commenced operations but will continue the investment operations of the
Mercantile Government & Corporate Bond Portfolio. (Returns are not provided for
Investor B Shares of the Mercantile Government & Corporate Bond Portfolio, since
no class of shares offered by the Mercantile Bond Index Portfolio will
reorganize into the same class of the Corresponding Firstar Fund as Investor B
Shares of the Mercantile Government & Corporate Bond Portfolio.) However,
comparisons of the total returns of the Mercantile U.S. Government Securities
Portfolio and Stellar U.S. Government Income Fund, and the Mercantile National
Municipal Bond Portfolio and Stellar Insured Tax-Free Bond Fund, multiple Funds
that are being reorganized into existing Firstar Funds that have not commenced
operations but will continue the operations of the Mercantile U.S. Government
Securities Portfolio and Mercantile National Municipal Bond Portfolio,
respectively, are not listed below. Performance shown is based on historical
earnings and is not predictive of future performance. Performance reflects
reinvestment of dividends and other earnings. Performance reflects fee waivers
in effect. If fee waivers were not in place, a Fund's performance would be
reduced.

APPENDIX VI - MANAGEMENT DISCUSSION OF FIRSTAR FUND PERFORMANCE
<PAGE>

                                                            (LOGO) FIRSTAR FUNDS

--------------------------------------------------------------------------------
                         INTERMEDIATE BOND MARKET FUND
--------------------------------------------------------------------------------

FIRSTAR INTERMEDIATE BOND MARKET FUND seeks to provide an annual rate of total
return comparable to that of the Lehman Brothers Intermediate
Government/Corporate Bond Index, before Fund expenses. In order to achieve its
objective, the Fund may invest in securities with long remaining maturities (10
years or longer) in addition to shorter bonds and notes.

This Fund's maturity mix gives the portfolio an overall AVERAGE MATURITY OF 5.5
YEARS and a DURATION OF 3.4 YEARS. Firstar Intermediate Bond Fund's duration is
just over three years and is between the durations of the other Firstar taxable
bond funds. If interest rates rise this Fund will display more downward price
movement than the Short-Term Bond Market Fund and less than the Bond IMMDEXTM
Fund. When interest rates fall, this Fund will exhibit more upward price
movement than Short-Term Bond Market Fund and less than the Bond IMMDEX/TM Fund.

During 1999, spreads on corporate bonds, asset-backed and mortgage-backed
securities tightened from historically wide levels in the fall of 1998. Since
that time, we selectively increased the Fund's exposure to these sectors. With
the spreads contracting, these sectors have contributed positively to the
performance of the Fund over the past year.

CORPORATE BONDS
The Fund's careful, research-intensive process of selecting investment-grade
corporate issues, asset-backed securities and mortgages gives the Fund a high-
quality focus. Currently the Fund's exposure to the corporate sector represents
56%. Sectors of the corporate market that we continue to favor include finance,
banking and brokerage.

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES
In general, we purchase only the highest rated (Aaa and Agency) collateralized
mortgage obligations (CMOs) and asset-backed securities (ABS). We utilize
shorter duration structures with more predictable "cash flow" characteristics.
This restrained use of mortgage and ABS instruments is a by-product of our
requirement to precisely measure the duration of the portfolio and ensure we
"match" the duration of the benchmark index at all times. The Firstar
Intermediate Bond Market Fund currently invests 22% in mortgage- and asset-
backed securities.

CONSISTENCY IS THE HALLMARK OF OUR APPROACH
Since Firstar Intermediate Bond Market Fund's inception on 1/5/93, we have
adhered to the same disciplined management approach. During the past 6+ years
the financial markets have become more volatile. THE HALLMARK OF OUR APPROACH
HAS BEEN THE FUND'S CONSISTENT PERFORMANCE IN ALL MARKET CLIMATES. Firstar
Intermediate's returns have been comparable to the benchmark in periods of
rising interest rates and falling interest rates. Our goal is to continue to
deliver this same consistent performance in the future.

We look forward to continuing to serve you as a Firstar Fund shareholder.

This chart assumes an initial investment of $10,000 made on 1/5/93 (inception).
Performance reflects fee waivers in effect. In the absence of fee waivers, total
return would be reduced. Performance is shown for Institutional shares, which
have lower expenses than Series A or Series B shares. If those fees and expenses
were reflected in the chart above, total return would have been reduced. Returns
shown include the reinvestment of all dividends and other distributions. Past
performance is not predictive of future performance. Investment return and
principal value will fluctuate, so that your shares, when redeemed, may be worth
more or less than their original cost.

<F4> The Lehman Brothers Intermediate Gov't./Corp. Bond Index is an unmanaged
     market value weighted index measuring both principal price changes of, and
     income provided by, the underlying universe of securities that comprise the
     index. Securities included in the index must meet the following critieria:
     fixed as opposed to variable rate; remaining maturity of one to ten years;
     minimum outstanding par value of $100 million; and rated investment grade
     or higher by Moody's, Standard & Poor's, or Fitch, in that order. An
     investment cannot be made directly in an index.

Effective at the close of business January 9, 1995, Firstar Funds began to offer
Series A shares. Effective at the close of business on February 28, 1999,
Firstar Funds began to offer Series B shares. Series A shares have a 3.75%
maximum sales load and are subject to an annual 0.25% service organization fee.
The load performance for the Series A shares has been restated to reflect the
impact of the current sales charge. Series A performance prior to January 10,
1995, does not reflect the service organization fees. If service organization
fees had been reflected, performance would be reduced. Series B shares have a
5.00% maximum deferred sales charge and are subject to an annual 0.25% service
organization fee and an annual 0.75% 12b-1 fee. Performance for all share
classes reflects fee waivers in effect. In the absence of fee waivers, total
return would be reduced.

--------------------------------------------------------------------------------
                       TAX-EXEMPT INTERMEDIATE BOND FUND
--------------------------------------------------------------------------------

FIRSTAR TAX-EXEMPT INTERMEDIATE BOND FUND seeks to provide current income exempt
from federal taxes and emphasizes total return with relatively low volatility of
principal. In order to achieve its objective, the Fund may invest in securities
with long remaining maturities (10 years or longer) in addition to shorter bonds
and notes. Currently the Fund does not purchase any issues which are subject to
the alternative minimum tax.

This Fund's maturity mix gives it an overall AVERAGE PORTFOLIO MATURITY OF 5.0
YEARS and a DURATION OF 4.1 YEARS. Because Tax-Exempt Intermediate Bond Fund's
duration is approximately four years, its NAV will be less price sensitive to
changes in interest rates than the typical municipal debt fund which, according
to Lipper Analytical Services, has an average duration of 7.8 years. The
intermediate average maturity and duration of this Fund protected the Fund from
the rise in interest rates over the last twelve months. While the Fund's
duration is the single most significant determinant of its return, the Fund's
sector allocation is also important. The Fund continues to emphasize high
quality holdings, favoring prerefunded, noncallable issues with predictable cash
flows.

PREREFUNDED MUNICIPAL BONDS
Prerefunded municipal bonds are municipal bonds that hold U.S. Treasury issues
in an escrow account, assuring the timely repayment of interest and principal.
As of October 31, 1999, OVER 68% OF THE FUND'S HOLDINGS WERE INVESTED IN
PREREFUNDED MUNICIPAL BONDS, RESULTING IN AN AVERAGE CREDIT QUALITY RATING OF
AAA FOR THE FUND. With credit spreads in the municipal bond market remaining
tight, the Fund's focus on superior quality issues will help minimize the
effects of any widening of credit spreads and will protect the Fund from any
general deterioration of credit quality in the municipal bond market.

CONSISTENCY IS THE HALLMARK OF OUR APPROACH
Since Firstar Tax-Exempt Intermediate Bond Fund's inception on 2/8/93, we have
adhered to the same disciplined management approach. The past 6+ years have
brought us more volatility in the fixed-income markets than many would have
expected. THE HALLMARK OF OUR APPROACH HAS BEEN THE FUND'S CONSISTENT
PERFORMANCE IN ALL MARKET CLIMATES. Our goal is to continue to deliver this same
consistent performance in the future.

We look forward to continuing to serve you as a Firstar Fund shareholder.

This chart assumes an initial investment of $10,000 made on 2/8/93 (inception).
Per formance reflects fee waivers in effect. In the absence of fee waivers,
total return would be reduced. Performance is shown for Institutional shares,
which have lower expenses than Series A or Series B shares. If those fees and
expenses were reflected in the chart above, total return would have been
reduced. Returns shown include the reinvestment of all dividends and other
distributions. Past performance is not predictive of future performance.
Investment return and principal value will fluctuate, so that your shares, when
redeemed, may be worth more or less than their original cost.

Effective at the close of business January 9, 1995, Firstar Funds began to offer
Series A shares. Effective at the close of business on February 28, 1999,
Firstar Funds began to offer Series B shares. Series A shares have a 3.75%
maximum sales load and are subject to an annual 0.25% service organization fee.
The load performance for the Series A shares has been restated to reflect the
impact of the current sales charge. Series A performance prior to January 10,
1995, does not reflect the service organization fees. If service organization
fees had been reflected, performance would be reduced. Series B shares have a
5.00% maximum deferred sales charge and are subject to an annual 0.25% service
organization fee and an annual 0.75% 12b-1 fee. Performance for all share
classes reflects fee waivers in effect. In the absence of fee waivers, total
return would be reduced.

                              BALANCED GROWTH FUND
-------------------------------------------------------------------------------

Firstar Balanced Growth Fund seeks capital appreciation combined with reasonable
income by investing in stocks and bonds. Typically, the Fund will invest 60% of
assets in common stocks of large-, medium- and small-sized companies, with the
balance invested in high quality bonds and money markets. As of October 31,
1999, the Fund consisted of 62% in common stocks, 37% in bonds and 1% in money
markets. The weighted average market capitalization of the common stocks was
$52.5 billion, considerably less than the $116 billion average market
capitalization of the Standard & Poor's 500 Stock Index. Bond holdings within
the portfolio had a weighted average duration of 5.4 years, matching the
duration of the Lehman Brothers Intermediate Government/Corporate Bond Index.
For the 12 months ended October 31, 1999, Firstar Balanced Growth Fund returned
5.9% (Institutional shares), compared with the return of 12.6% for the Lipper
Balanced Fund Index.

The world witnessed a remarkable change in economic circumstances in 1999. You
may recall high economic stress in 1998 led to three interest rate reductions by
the Federal Reserve. The rebound in the world economy in 1999 saw the Fed
reverse itself with three rate increases. Stock prices began the fiscal year
with a dramatic increase, with the S&P 500 returning 22.3% during the first six
months. The change in investor perception from low inflation and low interest
rates to higher inflation and interest rate risk slowed the market advance, with
the S&P 500 up 2.7% during the last half of the fiscal year. Technology stocks
led all others during the year with a phenomenal 69.4% return for the S&P
technology sector. This return was responsible for nearly half of the total
return of the Index, making diversification a losing strategy for the full year.

Our sector bet in technology and consumer cyclicals had a positive impact on the
portfolio. Offsetting this, however, was an overweighted position in financials,
which performed poorly in the face of high interest rates. Our 30%
portfolio weight to small- and mid-cap stocks also detracted from results as
these sectors continued to underperform the large-cap dominated S&P 500.

The objective of the fixed-income component of Firstar Balanced Growth Fund is
to provide an annual rate of total return comparable to the return of the Lehman
Brothers Intermediate Government/Corporate Bond Index. Our careful, research-
intensive process of selecting investment-grade corporate issues, mortgage- and
asset-backed securities gives the Fund a high-quality focus. One-half (50%) of
the fixed-income portion of the Fund is invested in obligations rated Aaa/AAA or
higher. Among corporate bonds, we have a preference for finance, banking and
brokerage issues along with dollar-denominated international ("Yankee")
securities. We believe these sectors represent exceptional value in the current
environment. Since the Fund's inception in 1992, we have adhered to the same
disciplined management approach. While the past seven years have brought us more
volatility in the fixed-income markets than many would have expected, we have
applied our consistent, risk-controlled style in all market climates.

During fiscal 1999, the stock market rewarded only the largest companies with
good price performance; however, we believe this trend is nearing exhaustion.
History has proven great returns are earned by investing in reasonably valued
companies of little notoriety. Today, that area is the small and medium-sized
area of the stock market. Firstar Balanced Growth Fund is among the few balanced
funds with a large commitment in these companies. With good value in our stock
holdings, and bonds offering 4-5% real yield (after inflation), we are excited
about the prospects for the Fund in the coming year.

Thank you for your continued confidence in Firstar Balanced Growth Fund.

                                EQUITY INDEX FUND
-------------------------------------------------------------------------------
Firstar Equity Index Fund seeks to provide investment returns, before Fund
expenses, comparable to the price and yield performance of publicly traded
stocks in the aggregate, as represented by the S&P 500 Index. The Fund does not
use traditional methods of financial and market analysis when making purchase
and sale decisions; rather, the Fund invests primarily in common stocks that
comprise the S&P 500 Index in proportion to their relative capitalization and
sector weightings.

Firstar Equity Index Fund's net asset value of $91.95 (Institutional shares) on
October 31 represents a total return of 2.6% for the last six months of the
fiscal year, which was comparable to the S&P's return of 2.7% over the same
period.

We believe by applying a capitalization weighting and sector balancing technique
that matches the structure of the S&P 500, as well as using S&P 500 futures
contracts to equitize the cash, the Fund should reasonably track the performance
of the index.

-------------------------------------------------------------------------------
                             GROWTH AND INCOME FUND
-------------------------------------------------------------------------------
For the fiscal year ended October 31, 1999, the Standard & Poor's 500 advanced
25.7%, propelled by a 69.4% gain for the technology sector. In fact, technology
stocks contributed over 40% of the return, with the "big five" - Microsoft,
Cisco, Lucent, Intel and America Online - responsible for one-quarter of the S&P
500's 12-month return. The Standard & Poor's 500 return without technology was
+15.1%. Strength was also seen in communication services stocks, with the
sector's +31% return driven by MCI WorldCom and Nextel. The consumer cyclicals
sector also beat the Index return, posting a +28% gain led by Wal-Mart and Home
Depot. What is notable regarding these top-performing companies is their high
relative price-to-earnings (P/E) ratios, averaging 64 times 1999 earnings, and
their low dividend yield, averaging .1%. Naturally this was a tough environment
for the Firstar Growth and Income Fund, which focuses on income-producing
securities at attractive multiples. Against the "headwinds," the Fund returned
+12.1% (Institutional shares) for the year.

In the Growth and Income Fund, we focus on the stocks of high quality companies
with predictable sales, earnings and cash flow growth, strong balance sheets and
innovative management. Standard & Poor's awards a stock rating of "A-" to "A+"
to companies with these characteristics. Companies with inconsistent or
negligible earnings histories and questionable balance sheets receive ratings of
"C" or "D." The Growth and Income portfolio has an average quality rating of "A-
 ." For the 12 months ended October of 1999, the lowest quality stocks were the
best performers, with "C" and "D"-rated companies up 48.4%. Companies with "A-"
ratings or greater were up a modest 5.8%.

The Growth and Income Fund focuses on companies that pay a dividend.
Historically this strategy has produced returns which are competitive in up
markets and outperform in down markets. The 22.4% annual return of the Growth
and Income Fund over the last five years is competitive with a +26.0% annual
gain for the Standard & Poor's 500 and a 20.1% return posted by the average
growth and income fund as measured by Morningstar. The Firstar Growth and Income
Fund is our most conservative equity fund, with a focus on providing competitive
risk-adjusted returns. The Fund, according to Morningstar, has experienced only
83% of the volatility of the S&P 500 and 88% of the volatility of the average
growth and income fund over the last five years. This combination of competitive
investment returns and low volatility gives the fund high marks for risk-
adjusted returns. We recognize, however, that this strategy does not work in all
market environments. The technology-driven market we have experienced over the
last 12 months is a case in point. Technology stocks generally do not pay
dividends and if they do, the payout is quite modest. The traditionally
defensive groups currently emphasized in the portfolio, including financials,
consumer staples and healthcare, posted 12-month returns of +19.5%, -.10% and
+10.4%, respectively. Simply stated, we own the sectors and the stocks that the
market is not favoring this year. This is a complete reversal from our 1998
experience when these groups, dominated by high quality companies, were in
favor.

The market's disdain for high quality companies over the last 12 months gave us
the opportunity to add a number of new companies to the portfolio at attractive
prices. Recent purchases for the Growth and Income Fund include Vulcan Materials
(we believe a major beneficiary of recent transportation legislation which will
increase highway construction spending by over 40% during the next several
years); Eli Lilly (a major pharmaceutical company with several promising new
drugs including Actos for Type II diabetes); Time Warner (the world's largest
media and entertainment company and, we believe, a beneficiary of the Internet
economy); and Walgreen's (one of America's largest drug retailers and an
indirect beneficiary of aging demographics and many successful new drug
launches).

As we approach the millennium, we believe the best opportunities in the market
are the 450 smaller companies within the S&P 500. Companies within this sector
with strong fundamentals should play catch-up to the lofty price-to-earnings
multiples of the "top 50." We are investing accordingly, with a $50 billion
average weighted market capitalization for the companies held in the Growth and
Income Fund versus a $116 billion average market capitalization for the Standard
& Poor's 500.

We thank you for your continued support.

-------------------------------------------------------------------------------
Firstar Growth Fund seeks long-term capital appreciation by investing in the
securities of large companies. As of October 31, 1999, the portfolio had a
weighted average market capitalization of $75.1 billion, up substantially from
the $48.9 billion on April 30, 1999. This compares with the Fund's primary
benchmark, the Standard & Poor's 500 (S&P 500), which had a weighted average
market capitalization of $116.1 billion on October 31. During the 12 months
ended October 31, the Growth Fund returned +18.2%, (Institutional shares)
trailing the S&P 500 +25.7%, and the Lipper Large Cap Core Fund average of
26.1%.

The last year has witnessed a remarkable change in economic circumstances for
the world economy and for the financial markets. High economic stress in 1998
led to three interest rate reductions by the Federal Reserve. The rebound in the
world economy in 1999 has seen the Fed reverse itself with three rate increases.
Stock prices began the fiscal year with a dramatic increase, with the S&P 500
returning 22.3% during the first six months. The change in investor perception
from low inflation and lower interest rates to higher inflation and interest
rate risk slowed the market advance, with the S&P 500 up 2.7% during the last
half of the fiscal year. Technology stocks led all others during the year with a
phenomenal 69.4% return for the S&P technology sector. This return was
responsible for nearly half of the total return of the index, making technology
stocks critical to Fund performance. No other sector contributed more than 11%
of the index return, making diversification a losing strategy for the full year.
Ironically, the year started in a higher-risk economic environment, and the best
returns were earned by those who took the greatest risk.

As we discussed in our mid-year report, the Fund started the year poorly in its
technology positions. Service company exposure was reduced in favor of those
companies which have more direct exposure to the construction of the Internet
and related communication services. New positions in Nortel and Sun Microsystems
appreciated over 50% during the last six months. Long-held positions in
Microsoft, Cisco Systems, Intel and First Data Systems were all up in excess of
50% for the full year, contributing 25% of the Fund's total return.
Additionally, advertising agency giants Omnicom and Interpublic Group were in
outstanding positions because of the surge in spending related to Internet
advertising. Large positions in Tyco, MCI WorldCom, Harley Davidson and American
International Group were also among the biggest contributors to return. A
significant reduction in our Tyco position was executed at the highest level of
prices during the year, making the stock's recent decline of less consequence.

The new year begins with the same themes driving the large company area of the
stock market. Technology stocks have roared to higher prices, taking their share
of the overall market to over 25%. This area has become the dominant sector in
the stock market, and we are determined to significantly improve our performance
in technology. New positions in JDS Uniphase, Qualcomm, Texas Instruments, Nokia
and EMC have already contributed to the portfolio performance. Our research
indicates that the lowest-risk way to invest in the explosive technology sector
is to own the leaders. Finance and health care companies represent good value
but are currently facing poor earnings growth (finance) or an election cycle
(health care) that are hindering their performance within the portfolio. We
believe better opportunities are ahead for these stocks. Finally, the consumer
continues to spend with a high degree of confidence. This gives us some
conviction that the next 12 months will be a good investment period for those
companies able to execute a profitable strategy in an increasingly competitive
world for consumer dollars.

We appreciate your continued support of Firstar Growth Fund.

                              EMERGING GROWTH FUND
-------------------------------------------------------------------------------
Firstar Emerging Growth Fund seeks capital appreciation through investments in
small-sized companies with stock market capitalizations generally between $250
million and $2 billion. The Fund's weighted average market capitalization is
currently $1.2 billion, just slightly above the S&P SmallCap 600 Index weighted
average of $1.0 billion. For the fiscal year ended October 31, 1999, the Fund
performed poorly against the S&P SmallCap 600 Index and the average small
capitalization money manager, following a year of significant relative
outperformance in fiscal 1998. Investors favored high price-to-earnings stocks
(due to minimal or zero earnings in the denominator) against consistent growth
companies that fit our growth-at-a-reasonable-price (GARP) style. With this
market environment, the Fund returned -2.6% (Institutional shares) in fiscal
1999, trailing the S&P SmallCap 600 Index at +12.0% and the Russell 2000 Index
at +14.9%. Large stocks continued to dominate the top-returning categories as
the S&P 500 Index rose 25.7% during fiscal 1999.

Fiscal and calendar 1999 returns were driven primarily by technology stocks
across all market capitalizations. Basically, a heavy concentration in
technology stocks was the distinguishing characteristic between winning
portfolios and losing portfolios. In calendar 1999, the technology sector of the
S&P SmallCap 600 Index rose 25.0% and added 4.4% to the Index's total return.
The cumulative effort of all other sectors in the Index subtracted 3.3% from the
Index's total return. In fact, 13 of the S&P SmallCap's top 15 performing stocks
were technology companies, with some rising over 200%. Despite an overall
technology weight above the Index, the Fund did not benefit from the technology
frenzy due to bigger industry weights in data processing stocks which performed
poorly all year. In essence, the Fund's top technology performers in fiscal 1998
became the bottom performers of fiscal 1999. Specifically, Acxiom, National Data
and Mastech fell over 30% as their relative earnings momentum slowed within the
technology space. Today, the Fund is overweighted in technology stocks and
maintains positions in fundamentally improving industries that were not owned in
the Fund in fiscal 1998 or early in fiscal 1999. Examples of these industries
are semiconductors, e-commerce software, electrical components and
telecommunications equipment. Since mid-year, these positions have helped the
Fund gain moderate ground against the Index.

In addition to the technology sector, the Fund was overweighted in financial
stocks and consumer cyclical companies. Finance companies, with rising interest
rates this year, have lagged the returns of most sectors. Our finance positions
did outperform the Index (-5% against -8%); however, the overweight in a
declining sector hurt the Fund's overall positioning. The Fund is now
underweighted in finance companies based on our belief that consolidation of
small-sized banks will slow next year and the possibility of further interest
rate hikes. In consumer cyclicals, specifically retail stocks, the Fund fell -
14% against -12% for the Index. We continue to hold a larger retail position
than the Index.

The weighted average forward price-to-earnings ratio of the Fund is 21x, about
10% higher than that of the S&P SmallCap 600 Index; however, the expected
earnings growth of the 80 companies held within the Fund is 28%, more than
double the Index's estimated growth of 12%. We believe the continued focus on
consistent, quality companies with accelerating growth provides a solid platform
for outperformance in fiscal 2000.

Thank you for your support.

This chart assumes an initial investment of $10,000 made on 8/15/97 (inception).
Performance reflects fee waivers in effect. In the absence of fee waivers, total
return would be reduced. Performance is shown for Institutional shares, which
have lower expenses than Series A or Series B shares. If those fees and expenses
were reflected in the chart above, total return would have been reduced. Returns
shown include the reinvestment of all dividends and other distributions. Past
performance is not predictive of future performance. Investment return and
principal value will fluctuate, so that your shares, when redeemed, may be worth
more or less than their original cost.

Dear Shareholder:

     On behalf of the Board of Trustees of Firstar Stellar Funds ("Stellar"), we
are pleased to invite you to a special meeting of shareholders of the Stellar
funds named above (each a "Stellar Fund") to be held at 10:00 a.m. (Eastern
time) on November 8, 2000 at the offices of Stellar's special counsel, Drinker
Biddle & Reath LLP, One Logan Square, 18/th/ and Cherry Streets, Philadelphia,
Pennsylvania (the "Special Meeting").  At the Special Meeting, you will be asked
to approve a proposed Agreement and Plan of Reorganization, dated as of
_________________ __, 2000 (the "Reorganization Agreement"), by and between
Stellar and Firstar Funds, Inc. ("Firstar"), which contemplates the
reorganization of your Stellar Fund into a corresponding fund of Firstar (each a
"Firstar Fund").

     Background.  Firstar Investment Research & Management Company, LLC
("FIRMCO"), a subsidiary of Firstar Corporation and investment adviser to
Firstar, is also the investment adviser for the Stellar Funds.  Prior to April
1, 2000, the Stellar Funds were managed by the Capital Management Division of
Firstar Bank, N.A.  As part of an internal restructuring of the investment
advisory function within the Firstar Corporation family, the investment
management resources of the Capital Management Division of Firstar Bank, N.A.
have been consolidated with those of FIRMCO.
<PAGE>

     In addition, Mercantile Bancorporation Inc. merged with Firstar Corporation
on September 17, 1999.  As a result of that merger, Mississippi Valley Advisors,
Inc. ("MVA"), formerly the investment adviser to Mercantile Mutual Funds, Inc.
("Mercantile"), became an indirect wholly-owned subsidiary of Firstar
Corporation.  On March 1, 2000, FIRMCO acquired all of the assets and
liabilities of MVA.  As a result of this acquisition, FIRMCO became investment
adviser to Mercantile.

     Firstar Bank, N.A. serves as the investment adviser to the Firstar Select
Funds ("Select").  Because FIRMCO now manages Firstar, Stellar and Mercantile
and its affiliate manages Select, FIRMCO has decided to combine the assets of
Firstar, Stellar, Mercantile and Select into thirty-six separate Firstar
investment portfolios.

     At the upcoming Special Meeting, you will be asked to approve the
reorganization of your Stellar Fund into a corresponding Firstar Fund (the
"Reorganization").  If shareholder approval is obtained, your Stellar Fund will
be reorganized into the corresponding Firstar Fund in mid to late November 2000,
when your shares in the Stellar Fund will be exchanged for shares of equal value
of a corresponding Firstar Fund.

     STELLAR'S BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT YOU VOTE TO APPROVE
THE PROPOSED REORGANIZATION.

     In considering these matters, you should note:

 .    The Same or Similar Objectives and Policies

     Four of the Stellar Funds are proposed to be reorganized into existing
Firstar Funds that will have investment objectives and policies following the
Reorganization that are, in general, similar to those of the corresponding
Stellar Fund:  (1) the Stellar Treasury Fund along with a separate portfolio
offered by Mercantile (the Mercantile Treasury Money Market Portfolio) will be
reorganized into the Firstar U.S. Treasury Money Market Fund, (2) the Stellar
Tax-Free Money Market Fund along with a separate portfolio offered by Mercantile
(the Mercantile Tax-Exempt Money Market Portfolio) will be reorganized into the
Firstar Tax-Exempt Money Market Fund, (3) the Stellar Fund will be reorganized
into the Firstar Balanced Income Fund, and (4) the Stellar Capital Appreciation
Fund will be reorganized into the Firstar MidCap Index Fund (the Firstar MidCap
Index Fund will have different investment objectives from the Stellar Capital
Appreciation Fund, but will hold many similar securities).

     Six of the Stellar Funds (i.e., the Stellar Ohio Tax-Free Money Market
Fund, Stellar Strategic Income Fund, Stellar Growth Equity Fund, Stellar
Relative Value Fund, Stellar Science & Technology Fund and Stellar International
Equity Fund) are proposed to be reorganized into newly organized Firstar Funds
that have been specifically created for the purposes of the Reorganization and
will continue the investment objective and policies of the particular Stellar
Fund that is being reorganized into it.

     Two of the Stellar Funds are proposed to be reorganized together with a
Mercantile Fund into existing Firstar Funds that have not yet commenced
operations. Each of these Firstar Funds

                                      -2-
<PAGE>

will continue the investment objectives and policies of one of the two Funds
being reorganized into it: (1) the Stellar U.S. Government Income Fund and
Mercantile U.S. Government Securities Portfolio will reorganize into the Firstar
U.S. Government Securities Fund, which will continue the investment objective
and policies of the Mercantile U.S. Government Securities Portfolio, and (2) the
Stellar Insured Tax-Free Bond Fund and the Mercantile National Municipal Bond
Portfolio will reorganize into the Firstar National Municipal Bond Fund, which
will continue the investment objective and policies of the Mercantile National
Municipal Bond Portfolio. The Mercantile U.S. Government Securities Portfolio
and the Mercantile National Municipal Bond Portfolio have investment objectives
and policies that are substantially similar to the investment objectives and
policies of their respective corresponding Stellar Fund.

 .     Same Value of Shares

      The Firstar Fund shares you receive in the Reorganization will have the
same total dollar value as the total dollar value of the Stellar Fund shares
that you held immediately prior to the Reorganization.  The exchange of Stellar
Fund shares for Firstar Fund shares will be tax-free under federal tax laws, and
no front-end or contingent deferred sales loads will be charged as a result of
the exchange.

 .     Reasons for the Reorganization

      The proposed Reorganization is expected to benefit Stellar Fund
shareholders by, among other things:

(i)   offering a larger and more diverse group of mutual funds to all
shareholders;

(ii)  actually or potentially reducing overall expenses by the achievement of
economies of scale associated with a larger asset base;

(iii) offering an opportunity for better investment performance due to an
expanded equity research staff that can focus on the core products available;

(iv)  offering distribution channels that will have a better understanding of
the proprietary products offered by Firstar and will be better able to
communicate FIRMCO's investment style to existing and prospective shareholders,
thereby increasing assets in the complex; and

(v)   allowing FIRMCO to effect portfolio transactions on more favorable terms.

      To see how the Reorganization will affect your Stellar Fund, please
carefully review the enclosed materials where you will find information on the
expenses, investment policies and services relating to the corresponding Firstar
Funds.

      The formal Notice of Special Meeting, a Combined Proxy
Statement/Prospectus and a Proxy Ballot are enclosed. If you own shares in more
than one of the Stellar Funds named above, more than one Proxy Ballot
accompanies these materials. Please be sure to vote and return each Proxy

                              Questions & Answers
                              -------------------


For Shareholders of Firstar Stellar Funds:

The following questions and answers provide an overview of the proposal to
reorganize your portfolio of Firstar Stellar Funds ("Stellar") into a
corresponding portfolio offered by Firstar Funds, Inc. ("Firstar").  We also
encourage you to read the full text of the combined proxy statement/prospectus
(the "Proxy/Prospectus") that follows.

--------------------------------------------------------------------------------

Q:   What are Stellar shareholders being asked to vote upon?

A:   Stellar shareholders are being asked to consider and approve a proposal to
reorganize each of the portfolios offered by Stellar (each, a "Stellar Fund")
into a corresponding portfolio of Firstar (each, a "Firstar Fund").

Q.   Why has the reorganization of the Stellar Funds into corresponding Firstar
Funds been recommended?

A:   The Board of Trustees of Stellar and the Board of Directors of Firstar have
each determined that the reorganization of each of the Stellar Funds into its
respective corresponding Firstar Fund is in the best interests of the respective
shareholders of each such Fund.  Among the benefits for Stellar Fund
shareholders considered by the Stellar Board of Trustees were:  access to a
larger and more diverse group of mutual funds; access to the expanded equity
research capabilities of Firstar Investment Research & Management Company, LLC;
the potential for individual Firstar Funds to achieve greater portfolio
diversification and engage in investment transactions on potentially more
advantageous terms; the ability to spread relatively fixed costs, such as legal
fees, over a larger asset base; and the ability of Firstar to maintain existing
clients and attract new investors.

Q:   What is the anticipated timing of the reorganization?

A:   The meeting of shareholders to consider the proposal is scheduled to occur
on November 8, 2000.  If all necessary approvals are obtained, the proposed
reorganization will likely take place in mid to late November 2000.

Q:   Who will receive the Proxy/Prospectus material?

A:   The Proxy/Prospectus has been mailed to all persons and entities that held
shares of record in a Stellar Fund on September 15, 2000.  Please note that in
some cases record ownership of and/or voting authority over Stellar Fund shares
may reside with a fiduciary or other agent.  In these cases, the fiduciary or
other agent may receive the combined Proxy/Prospectus.
<PAGE>

Q:   How are the Stellar Funds proposed to be reorganized?

A:   As you may know, Stellar consists of twelve separate mutual funds.  The
proposed agreement and plan of reorganization for these funds, approved by the
Stellar Board of Trustees, contemplates the reorganization of four of these
Stellar Funds into four Firstar Funds having similar investment objectives and
policies, except that the Stellar Capital Appreciation Fund will be merged into
the Firstar MidCap Index Fund which holds many similar securities but has
different investment objectives.  In addition, six Stellar Funds will be
reorganized into six Firstar Funds (each a "Shell Firstar Fund") that are being
created to continue the current operations of these Stellar Funds.  The
investment objectives and strategies of each of these six Shell Firstar Funds
will be identical to those of its corresponding Stellar Fund.  Each of the two
remaining Stellar Funds will be reorganized together with a portfolio of
Mercantile Mutual Funds, Inc. (each a "Mercantile Fund") into a separate Firstar
Fund being created in connection with the reorganization that will continue the
investment objectives and policies of the Mercantile Fund. The investment
objectives and strategies of each of these two Mercantile Funds are
substantially similar to those of the relevant Stellar Fund.

     Under the proposed agreement and plan of reorganization, each Stellar Fund
will be reorganized into the Firstar Fund listed directly opposite such Stellar
Fund in the table below. Those Stellar Funds reorganizing into Shell Firstar
Funds are printed in bold text:

Q:   Which class of shares of the Firstar Funds will I receive in the
reorganization?

A:   Each Stellar Fund (except the Stellar Tax-Free Money Market Fund, Stellar
Ohio Tax-Free Money Market Fund and Stellar International Equity Fund) and each
Firstar Fund offer multiple classes of shares to investors.  The various classes
of Stellar and Firstar Fund shares all represent interests in the same portfolio
of securities owned by the Stellar Fund or Firstar Fund, but have different
expenses and characteristics, such as distribution and shareholder servicing
arrangements, that are intended to meet the needs of different types of
investors.  In general, eligibility to purchase a particular class of Stellar
Fund shares or Firstar Funds shares turns on whether the investor is
characterized as an "institutional investor" or a "retail investor."

     To determine which class of shares of the relevant Firstar Fund that you
will receive in the reorganization, find the name of your Stellar Fund in column
1 of the table below, then find the name of the class of shares you currently
own in the Stellar Fund listed under the name of your Stellar Fund. The name of
the class of shares you will receive in the reorganization is listed in column 2
of the table below directly opposite the name of the class of shares you
currently own in the Stellar Fund.

Q:   What are the costs and federal tax implications to shareholders in
connection with the proposed reorganization?

A:   In general, the costs of the reorganization will not be borne by Stellar
Fund shareholders. No sales charge will be imposed on the shares of the Firstar
Funds issued to you in the reorganization, which means that the aggregate value
of the Firstar Fund shares issued to you will be equal to the aggregate value of
the Stellar Fund shares that you own immediately prior to the reorganization. In
addition, the exchange of Stellar Fund shares for Firstar Fund shares will be
tax-free under federal tax laws. However, the sale of securities by a Stellar
Fund, prior to the reorganization, whether in the ordinary course of business or
in anticipation of the reorganization, could increase the amount of the taxable
capital gains distribution made prior to the reorganization. See "The
Reorganization -Federal Income Tax Considerations" for additional information.

                        To Be Held On November 8, 2000

To Shareholders of Firstar Stellar Funds:

     NOTICE IS GIVEN THAT a special meeting of the shareholders (the "Special
Meeting") of each fund of the Firstar Stellar Funds named above (each, a
"Stellar Fund" and together, the "Stellar Funds"), each of which is a separate
series of Firstar Stellar Funds ("Stellar"), will be held at 10:00 a.m. (Eastern
time), on November 8, 2000, at the offices of Stellar's special counsel, Drinker
Biddle & Reath LLP, One Logan Square, 18/th/ & Cherry Streets, Philadelphia,
Pennsylvania, for the purpose of considering and voting upon:

     ITEM 1.  A proposal to approve an Agreement and Plan of Reorganization by
     and between Stellar and Firstar Funds, Inc. ("Firstar"), which provides for
     and contemplates:  (a) the transfer of substantially all of the assets and
     liabilities of each Stellar Fund to a corresponding investment portfolio of
     Firstar (each, a "Firstar Fund") in exchange for shares of designated
     classes of the corresponding Firstar Fund of equal value; (b) the
     distribution of the shares of the designated classes of each such Firstar
     Fund to the shareholders of the corresponding Stellar Fund in liquidation
     of each of the Stellar Funds;
<PAGE>

     and (c) the deregistration under the Investment Company Act of 1940, as
     amended, and the termination under state law of Stellar.

     ITEM 2.  Such other business as may properly come before the Special
     Meeting or any adjournment(s) thereof.

     Item 1 is described in the attached Combined Proxy Statement/Prospectus.
Your Trustees unanimously recommend that you vote in favor of the proposal.

     Shareholders of record as of the close of business on September 15, 2000
are entitled to notice of, and to vote at, the Special Meeting or any
adjournment(s) thereof.

     You are requested to mark, date, sign and return promptly in the enclosed
envelope each accompanying Proxy Ballot that is being solicited by the Stellar
Board of Trustees. This is important to ensure a quorum at the Special Meeting.
You also may return proxies by: 1) touch-tone telephone voting or 2) voting on-
line. Proxies may be revoked at any time before they are exercised by submitting
to Stellar a written notice of revocation or a subsequently executed proxy or by
attending the Special Meeting and voting in person.

                              By Order of the Board of Trustees


                              Bruce Laning
                              President


We need your proxy vote immediately.  You may think that your vote is not
important, but it is vital.  By law, the Special Meeting will have to be
adjourned without conducting any business if less than a majority of the shares
eligible to vote are represented.  In that event, Stellar would continue to
solicit votes in an attempt to achieve a quorum.  Your vote could be critical in
allowing Stellar to hold the Special Meeting as scheduled, so please return your
Proxy Ballot(s) immediately or vote on-line or by telephone.

          This combined proxy statement/prospectus ("Proxy/Prospectus") is being
sent to shareholders of the Firstar Stellar Treasury Fund, Firstar Stellar Tax-
Free Money Market Fund, Firstar Stellar Ohio Tax-Free Money Market Fund, Firstar
Stellar Strategic Income Fund, Firstar Stellar U.S. Government Income Fund,
Firstar Stellar Insured Tax-Free Bond Fund, Firstar Stellar Growth Equity Fund,
Firstar Stellar Relative Value Fund, Firstar Stellar Science & Technology Fund,
Firstar Stellar Fund, Firstar Stellar Capital Appreciation Fund and Firstar
Stellar International Equity Fund (each a "Stellar Fund" and collectively the
"Stellar Funds").  The Board of Trustees of Firstar Stellar Funds ("Stellar")
has called a Special Meeting of Shareholders (the "Special Meeting") at the
offices of Stellar's special counsel, Drinker Biddle & Reath LLP, One Logan
Square, 18/th/ & Cherry Streets, Philadelphia, Pennsylvania, on November 8, 2000
at 10:00 a.m. Eastern time.

At the Special Meeting, shareholders will be asked:

 .    To approve a proposed Agreement and Plan of Reorganization dated as of
     __________, 2000 (the "Reorganization Agreement"), by and between Stellar
     and Firstar Funds, Inc. ("Firstar"), which provides for and contemplates
     (a) the transfer of substantially all of the assets and liabilities of each
     Stellar Fund to a corresponding investment portfolio of Firstar (each a
     "Firstar Fund" and collectively, the "Firstar Funds") in exchange for
     shares of equal value of designated classes of the corresponding Firstar
     Fund; (b) the distribution of the shares of the designated classes of the
     corresponding Firstar Fund to shareholders of each Stellar Fund in
     liquidation of each of the Stellar Funds; and (c) the deregistration under
     the Investment Company Act of 1940, as amended (the "1940 Act"), and
     termination under state law, of Stellar.

          The Reorganization Agreement, the form of which is attached as
Appendix I to this Proxy/Prospectus, provides for the transfer of substantially
all of the assets and liabilities of each Stellar Fund to a corresponding
Firstar Fund in exchange for Retail A Shares, Retail B Shares, or

                                      -1-
<PAGE>

Institutional Shares, as applicable, of the corresponding Firstar Fund of equal
value. Stellar and Firstar are both registered open-end management investment
companies (mutual funds).

     As a result of the reorganization, shareholders of the Stellar Funds will
become shareholders of the Firstar Funds (the Stellar Funds and Firstar Funds
are sometimes referred to as the "Funds").

     The transactions contemplated by the Reorganization Agreement are referred
to collectively as the "Reorganization."

     If the Reorganization Agreement is approved and the transactions
contemplated thereby are consummated, Stellar will transfer all of its assets
and liabilities, deregister as a registered investment company and terminate
under Massachusetts law.

     This Proxy/Prospectus sets forth concisely the information that a Stellar
Fund shareholder should know before voting and investing, and should be retained
for future reference.  It is both Stellar's proxy statement for the Special
Meeting and a prospectus for the Firstar U.S. Treasury Money Market Fund,
Firstar Tax-Exempt Money Market Fund, Firstar U.S. Government Securities Fund,
Firstar National Municipal Bond Fund, Firstar Balanced Income Fund and Firstar
MidCap Index Fund (the "Existing Firstar Funds").  It is not a prospectus for
the Firstar Ohio Tax-Exempt Money Market Fund, Firstar Strategic Income Fund,
Firstar Large Cap Growth Fund, Firstar Relative Value Fund, Firstar Science &
Technology Fund and Firstar Global Equity Fund (the "Shell Firstar Funds")
because these funds were created to continue the business of their corresponding
Stellar Funds.  Each of these Shell Firstar Funds will have substantially the
same investment objectives, policies and restrictions as its respective
corresponding Stellar Fund.

     Additional information is set forth in the Statement of Additional
Information relating to this Proxy/Prospectus and in the prospectuses dated
March 31, 2000 for the Stellar Funds, which are incorporated herein by
reference.  Each of these documents is on file with the Securities and Exchange
Commission (the "SEC"), and is available without charge by calling or writing
Stellar at the telephone number or address stated above.  The information
contained in the current prospectuses of the Existing Firstar Funds (other than
the Firstar U.S. Government Securities Fund and Firstar National Municipal Bond
Fund), dated March 1, 2000, for the designated share classes, and ____, 2000,
with respect to the Firstar U.S. Government Securities Fund and Firstar National
Municipal Bond Fund, also is incorporated by reference into this
Proxy/Prospectus.  In addition, current prospectuses for the designated share
classes of the Existing Firstar Funds accompany this Proxy/Prospectus.  The
Annual Report for the year ended October 31, 1999 and the Semi-Annual Report for
the period ended April 30, 2000 for the Existing Firstar Funds (other than the
Firstar U.S. Government Securities Fund and Firstar National Municipal Bond
Fund, which have not commenced operations as of the date of this
Proxy/Prospectus) are available without charge by calling or writing Firstar at
the telephone number or address stated above.  Each of these documents is also
available on the SEC's website at www.sec.gov.

     This Proxy/Prospectus is expected to be first sent to shareholders on or
about September ___, 2000.

                                  FEE TABLES

     The following tables show which classes of shares of the following Firstar
Funds are projected to experience higher, lower or the same annualized per share
total operating expense ratios as the corresponding class of shares of their

time after October 31, 2001.

                                    SUMMARY

     The following is a summary of certain information relating to the proposed
Reorganization between Firstar and Stellar.  More complete information is
contained elsewhere in this Proxy/Prospectus, the Prospectuses and Statements of
Additional Information of Firstar and Stellar, and the Appendices attached
hereto.

     Proposed Reorganization.  The Reorganization Agreement provides for and
contemplates: (1) the transfer of substantially all of the assets and
liabilities of each Stellar Fund to a corresponding investment portfolio offered
by Firstar (each, a "Corresponding Firstar Fund"), in exchange for shares of the
designated classes of such Corresponding Firstar Fund of equal value (such
shares of the designated classes of such Corresponding Firstar Fund, the
"Firstar Fund Shares"); (2) the distribution of the Firstar Fund Shares to the
shareholders of the Stellar Funds in liquidation of each of the Stellar Funds;
and (3) the deregistration under the 1940 Act and the termination under state
law of Stellar.  It is anticipated that the Reorganization will take place in
two stages, with six of the Stellar Funds first transferring their respective
assets and liabilities to six corresponding Existing Firstar Funds with the same
or similar investment objectives and policies in exchange for the Firstar Fund
Shares issued by such corresponding Existing Firstar Funds, and a week later the
remaining six Stellar Funds transferring their respective assets and liabilities
to six Shell Firstar Funds organized for the purpose of acquiring the assets and
liabilities, and then continuing the business, of such Stellar Fund, in exchange
for the Firstar Fund Shares issued by such corresponding Shell Firstar Funds.
The liquidation of each Stellar Fund, and the distribution of the Firstar Fund
Shares to the respective shareholders of such Stellar Fund, shall occur
immediately after the receipt by such Stellar Fund of all of the Firstar Fund
Shares to be received by such Stellar Fund in the Reorganization.  The
Reorganization is subject to a number of conditions, including approval by the
shareholders of each Stellar Fund.

     As a result of the proposed Reorganization, each Stellar Fund shareholder
will become a shareholder of its Corresponding Firstar Fund and will hold,
immediately after the Reorganization, Firstar Fund Shares in such Corresponding
Firstar Fund having a total dollar value equal to the total dollar value of the
shares such shareholder held in the Stellar Fund immediately prior to the
effectiveness of the Reorganization.  The exchange of shares in the
Reorganization will be tax-free under federal tax laws and shareholders of the
Firstar Funds and the Stellar Funds will not pay any sales charge as a result of
the exchange of the shares in the Reorganization.

     The following chart summarizes which share class of each Firstar Fund a
Stellar Fund shareholder will receive in the Reorganization:

     The Reorganization is expected to occur in mid to late November 2000 or
such later date as may be determined pursuant to the Reorganization Agreement.
For more information about the Reorganization and the Reorganization Agreement,
see the Section below entitled "The Reorganization-Description of the
Reorganization Agreement."

     At the same time that the Stellar Funds are reorganized into the Firstar
Funds, it is expected that the investment portfolios offered by Mercantile
Mutual Funds, Inc. ("Mercantile") and Firstar Select Funds ("Select") will be
reorganized into certain investment portfolios offered by Firstar, including in
the case of the Mercantile reorganization certain of the Corresponding Firstar
Funds.  In particular it is expected that (1) the Stellar Treasury Fund together
with the Mercantile Treasury Money Market Portfolio will be reorganized into the
Firstar U.S. Treasury Money Market Fund, (2) the Stellar Tax-Free Money Market
Fund together with the Mercantile Tax-Exempt Money Market Portfolio will be
reorganized into the Firstar Tax-Exempt Money Market Fund, (3) the Stellar U.S.
Government Income Fund together with the Mercantile U.S. Government Securities
Portfolio will be reorganized into the Firstar U.S. Government Securities Fund,
and (4) the Stellar Insured Tax-Free Bond Fund together with the Mercantile
National Municipal Bond Portfolio will be reorganized into the Firstar National
Municipal Bond Fund.

     If the Reorganization Agreement is approved by the Stellar shareholders at
the Special Meeting, it is expected that the Reorganization will be completed
whether or not the Mercantile reorganization or Select reorganization are
completed.

* It is expected that upon consummation of the reorganization of the Stellar
  Treasury Fund and Mercantile Treasury Money Market Portfolio into the Firstar
  U.S. Treasury Money Market Fund, the Firstar U.S. Treasury Money Market Fund
  will adopt investment objectives, policies and restrictions that are
  substantially the same as the investment objectives, policies and restrictions
  of the Stellar Treasury Fund.  The Firstar U.S. Treasury Money Market Fund,
  however, will retain its fundamental investment limitations, which are
  similar, but not identical, to the Stellar Treasury Fund's fundamental
  investment limitations.

     The investment objective, policies and restrictions of the (1) Stellar Ohio
Tax-Free Money Market Fund, (2) Stellar Strategic Income Fund, (3) Stellar
Growth Equity Fund, (4) Stellar Relative Value Fund, (5) Stellar Science &
Technology Fund, and (6) Stellar International Equity Fund (collectively, the
"Continuing Stellar Funds") are substantially the same as those of their
corresponding Shell Firstar Funds, because the Shell Firstar Funds have each
been organized solely in connection with this Reorganization to acquire the
assets and continue the business of its corresponding Continuing Stellar Fund.

                                      -14-
<PAGE>

     The investment objectives, policies and restrictions of each of the other
Stellar Funds (collectively the "Reorganizing Stellar Funds") are, in general,
substantially the same and/or similar to those of its Corresponding Firstar Fund
(except that the Firstar MidCap Index Fund will have different investment
objectives from the Stellar Capital Appreciation Fund, but will hold many
similar securities). However, there are certain differences between the
investment policies and restrictions of these other Stellar Funds and their
Corresponding Firstar Funds. For additional information, see "Comparison of
Stellar Funds and Firstar Funds - Investment Objectives and Policies" and
Appendix III.

     FIRMCO, a Wisconsin limited liability company and subsidiary of Firstar
Corporation, a bank holding company, serves as investment adviser to both the
Stellar Funds and the Firstar Funds. FIRMCO, with principal offices at Firstar
Center, 777 East Wisconsin Avenue, 8th Floor, Milwaukee, Wisconsin 53202, has
provided investment advisory services since 1986. FIRMCO currently has $50
billion in assets under management.

     Prior to April 1, 2000, the Stellar Funds were managed by the Capital
Management Division of Firstar Bank, N.A., which is also a wholly owned
subsidiary of Firstar Corporation. As part of an internal restructuring of the
investment advisory function within Firstar Corporation, the investment
management resources of the Capital Management Division of Firstar Bank, N.A.
have been consolidated with those of FIRMCO. Management of the funds was not
affected by this consolidation.


                                   Table II

     The following table summarizes whether the contractual advisory fee rate of
a Firstar Fund (on a pro forma basis, after giving effect to the Reorganization)
is higher, lower or the same as its corresponding Stellar Fund by showing the
differential between the Firstar Fund (on a pro forma basis, after giving effect
to the Reorganization) and the Stellar Fund contractual fee rate.

Firstar Tax-Exempt Money Market Fund                   0.05% lower
Firstar Ohio Tax-Exempt Money Market Fund              0.05% lower

                                      -15-
<PAGE>

Firstar MidCap Index Fund                              0.70% lower
Firstar Global Equity Fund                             same contractual fee rate

*  For example, the Firstar U.S. Treasury Money Market Fund has a contractual
advisory fee rate of 0.44% and its corresponding Stellar Fund has a contractual
advisory fee rate of 0.50%, thus the contractual advisory fee rate of the
Firstar U.S. Treasury Money Market Fund is 0.06% lower than the contractual
advisory fee rate of its corresponding Stellar Fund.

     For more on advisory fee rates, see "Comparison of Stellar Funds and
Firstar Funds - Investment Advisory Services - Table V."

     Advisory fees, however, are only one type of fee and expense paid by mutual
funds. As noted previously in "Fee Tables - Tables I(A), I(B) and I(C)," (i) all
Stellar Class A and Class B shareholders who will be receiving Institutional
Shares of the Corresponding Firstar Fund in the Reorganization will have total
operating expense ratios (after fee waivers) that are lower after the
Reorganization; (ii) Stellar Class A shareholders who will be receiving Retail A
Shares of the Corresponding Firstar Fund in the Reorganization will have total
operating expense ratios (after fee waivers) that are lower after the
Reorganization with respect to four out of eight Stellar Funds, higher with
respect to two out of eight Stellar Funds and the same with respect to two out
of eight Stellar Funds; (iii) Stellar Class B shareholders who will be receiving
Retail B Shares of the Corresponding Firstar Fund in the Reorganization will
have total operating expense ratios (after fee waivers) that are lower after the
Reorganization with respect to two out of eight Stellar Funds and higher with
respect to six out of eight Stellar Funds; (iv) all Stellar Class C shareholders
will have total operating expense ratios (after fee waivers) that are lower
after the Reorganization; and (v) Stellar Class Y shareholders will have total
operating expense ratios (after fee waivers) that are lower after the
Reorganization with respect to three out of five Stellar Funds and the same with
respect to two out of five Stellar Funds.

     Firstar Mutual Fund Services, LLC ("FMFS") serves as administrator of the
Firstar Funds. FMFS also serves as administrator of the Stellar Funds. FMFS
serves as transfer agent to both the Stellar Funds and Firstar Funds. Firstar
Bank, N. A. serves as custodian to both the Stellar Funds and the Firstar Funds.
The distributor of Stellar and Firstar is Quasar Distributors LLC. For a
detailed description of the management of the Firstar Funds, including the
service providers to the Firstar Funds, see "Comparison of Stellar Funds and
Firstar Funds - Other Service Providers for the Stellar Funds and the Firstar
Funds" and the Firstar Funds prospectuses that accompany this Proxy/Prospectus.

     The purchase, redemption, exchange, dividend and other policies and
procedures of the Stellar Funds and their Corresponding Firstar Funds are
generally similar. There are, however, some differences. For example,
shareholders of Firstar Funds are able to purchase (other than initial
purchases), exchange and redeem shares via the Internet. For more information,
see "Comparison of Stellar Funds and Firstar Funds - Shareholder Transactions
and Policies," "Comparison of Stellar Funds and Firstar Funds -Share Structure"
and Appendix IV to this Proxy/Prospectus.

     Federal Income Tax Consequences. The exchange of shares in the
Reorganization is not expected to result in the recognition, for federal income
tax purposes, of gain or loss by the Stellar Funds, the Firstar Funds or their
respective shareholders. The sale of securities by the Stellar Funds prior to
the Reorganization, whether in the ordinary course of business or in
anticipation of the Reorganization, could increase the amount of the taxable
capital gains distributions made prior to the Reorganization. See "The
Reorganization - Federal Income Tax Considerations" for additional information.

     Stellar and Firstar Board Consideration. During its deliberations,
Stellar's Board of Trustees (with the advice and assistance of its counsel)
reviewed, among other things: (1) the potential effect of the Reorganization on
the shareholders of the Stellar Funds; (2) the capabilities, practices and
resources of FIRMCO; (3) the investment advisory and other fees paid by the
Firstar Funds, and the historical and projected expense ratios of the Firstar
Funds as compared with those of the Stellar Funds and industry peer groups; (4)
the investment objectives, policies and limitations of the Firstar Funds and
their relative compatibility with those of the Stellar Funds; (5) the historical
investment performance records of the Stellar Funds and the Firstar Funds,
relative to each other and to peer groups or indices; (6) the shareholder
services offered by Firstar; (7) the terms and conditions of the Reorganization
Agreement; (8) the anticipated tax consequences of the Reorganization for the
respective Stellar Funds and their shareholders; and (9) the number of
investment portfolio options that would be available to shareholders after the
Reorganization. The Stellar Board also considered FIRMCO's belief that the
Reorganization would eliminate certain duplicative shareholder costs and market
overlap, facilitate consideration of FIRMCO's managerial resources and enhance
generally operational efficiencies and focus with respect to the mutual funds
advised by FIRMCO. For additional information, see "The Reorganization -Stellar
Board Consideration."

     Based upon their evaluation of the information presented to them, and in
light of their fiduciary duties under federal and state law, the Board of
Trustees of Stellar, including all of the non-interested members of the Board,
determined that participation in the Reorganization, as contemplated by the
Reorganization Agreement, was in the best interests of the shareholders of each
Stellar Fund and that the interests of the existing shareholders of each Stellar
Fund would not be diluted as a result of the Reorganization.

     The Stellar Board of Trustees unanimously recommends that shareholders of
each Stellar Fund approve the Reorganization Agreement.

     After considering the relevant factors, the Firstar Board of Directors
similarly found that participation in the Reorganization was in the best
interests of the Firstar Funds and that the interests of the shareholders of the
Firstar Funds would not be diluted as a result of the Reorganization.

     Principal Risk Factors. Because each of the Shell Firstar Funds is being
created to acquire the assets and liabilities, and then continue the business,
of its corresponding Continuing Stellar Fund, an investment in a Shell Firstar
Fund involves risks that are substantially the same as those of investing in its
corresponding Continuing Stellar Fund. The investment objectives, policies and
restrictions of each other Firstar Fund are, in general, the same as or similar
to those

                                      -17-
<PAGE>

of its corresponding Stellar Fund. Accordingly, an investment in an Existing
Firstar Fund involves risks that are similar to those of investing in its
corresponding Stellar Fund. The principal risks applicable to the Stellar Funds
and the Firstar Funds are described in the table below. Additional information
regarding these risks and other risks to which each of the Funds are subject are
described in the prospectuses and statements of additional information for the
Funds.

     "Stellar Money Market Funds" means, collectively, the Stellar Treasury
Fund, Stellar Tax-Free Money Market Fund and Stellar Ohio Tax-Free Money Market
Fund.

     "Firstar Money Market Funds" means, collectively, the Corresponding Firstar
Funds of the Stellar Money Market Funds.

     "Stellar Bond Funds" means, collectively, the Stellar Strategic Income
Fund, Stellar U.S. Government Income Fund and Stellar Insured Tax-Free Bond
Fund.

     "Firstar Bond Funds" means, collectively, the Corresponding Firstar Funds
of the Stellar Bond Funds.

     "Stellar Equity Funds" means, collectively, the Stellar Growth Equity Fund,
Stellar Relative Value Fund, Stellar Science & Technology Fund, Stellar Fund,
Stellar Capital Appreciation Fund and Stellar International Equity Fund.

Changes in interest rates will also          Stellar Growth Equity, Relative Value,
affect a Fund's yield.  A decline in         Science & Technology, Stellar and
interest rates may lead to a decline in a    International Equity Funds
Fund's yield.  Lower rated securities are
subject to greater interest rate risk
than higher rated securities.
-----------------------------------------------------------------------------------------
Fixed Income Risk - The rate of income on    Firstar Money Market and Bond Funds
Fund shares will vary from day to day so
that the dividends on your investment        Stellar Money Market and Bond Funds
will vary.
-----------------------------------------------------------------------------------------
Market Risk - The value of the securities    Firstar Bond and Equity Funds
in which a Fund invests may go up or down
in response to the prospects of              Stellar Bond and Equity Funds
individual companies and/or general
economic conditions.
-----------------------------------------------------------------------------------------
Volatility Risk - The value of your          Firstar Bond and Equity Funds

difficult or impossible to sell at the       Government Securities Funds
time and price that the investment

price, sell other securities instead or      Funds
forgo an investment opportunity, any of
which could have a negative effect on
fund management or performance.
-----------------------------------------------------------------------------------------
Foreign Investment Risk - A Fund's           Firstar Strategic Income, Large Cap Growth,
investments in foreign securities are        Relative Value and Global Equity Funds
subject to foreign risks.  Foreign stocks
involve special risks not typically          Stellar Strategic Income, U.S. Government
associated with U.S. stocks.  The stocks     Income, Growth Equity, Relative Value,
held by a Fund may underperform other        Stellar, Capital Appreciation and
types of stocks, and they may not            International Equity Funds
increase or may decline in value.
Foreign investments may be riskier than
U.S. investments because of factors such
as foreign government restrictions,
changes in currency exchange rates,
incomplete financial information about
the issuers of securities, and political
or economic instability.  Foreign stocks
may be more volatile and less liquid than
U.S. stocks.
-----------------------------------------------------------------------------------------
Futures and Options on Futures Risk - A      Firstar National Municipal Bond, Large Cap
Fund may use futures and options on          Growth, Science and Technology and Global
futures for hedging purposes only. The       Equity Funds
hedging strategy may not be successful if
the portfolio manager is unable to           Stellar U.S. Government Income, Insured

Small and Medium Size Companies Risk - A     Firstar Large Cap Growth, Science &
Fund may invest in the stocks of small-      Technology, MidCap Index and Global Equity
to medium-size companies. Small- and         Funds
medium-size companies often have narrower

Prepayment Risk - An issuer may exercise     Firstar Strategic Income, U.S. Government
its right to pay principal on an             Securities, National Municipal Bond, Large
obligation held by a Fund (such as a         Cap Growth and Balanced Income Funds

earlier than expected.  This may happen      Stellar Strategic Income, U.S. Government
when there is a decline in interest          Income, Growth Equity and Stellar Funds
rates.  These events may make a Fund

Real Estate Investment Trust (REIT) Risk -   Firstar Strategic Income and Large Cap
Equity and mortgage REITs depend on          Growth Funds
management skills and are not
diversified. As a result, REITs are          Stellar Strategic Income, Growth Equity and

flow and may be subject to defaults by
borrowers and self-liquidation.
Additionally, equity REITs may be
affected by any changes in the value of
the underlying property owned by the
trusts. Mortgage REITs may be affected by
the quality of any credit extended.
-----------------------------------------------------------------------------------------
Municipal Government Risk -The ability of    Firstar Tax-Exempt Money Market, Ohio
a state or local government issuer to        Tax-Exempt Money Market and National

factors, including economic conditions,

Some municipal securities are payable        Bond Funds
only from limited revenue sources or by
private entities.
-----------------------------------------------------------------------------------------
Non-Diversification Risk - The Fund is       Firstar Ohio Tax-Exempt Money Market and
non-diversified, which means that it can     Science & Technology Funds
invest a large percentage of its assets
in a small number of issuers.  As a          Stellar Ohio Tax-Free Money Market and
result, a change in the value of any one     Science & Technology Funds
investment held by the Fund may affect

Municipal Lease Obligations Risk - A Fund    Firstar Tax-Exempt Money Market and
may acquire municipal lease obligations      National Municipal Bond Funds
that are issued by a state or local
government or authority to acquire land      Stellar Tax-Free Money Market and Insured
and a wide variety of equipment and          Tax-Free Bond Funds

Portfolio Turnover Risk - The investment     Firstar Strategic Income Fund
adviser may engage in active trading of
its portfolio securities to achieve its      Stellar Strategic Income and Capital
investment goals. This practice could        Appreciation Funds
result in a Fund experiencing a high
turnover rate (100% or more).  High
portfolio turnover rates lead to
increased costs, could cause you to pay
higher taxes and could negatively affect
a Fund's performance.
-----------------------------------------------------------------------------------------
Concentration Risk - A Fund may invest       Firstar Tax-Exempt Money Market and
more than 25% of its total assets in         National Municipal Bond Fund
municipal obligations issued by entities
located in the same state and the
interest on which is paid solely from
revenues of similar projects.  As a
result, changes in economic, business or
political conditions relating to a
particular state or types of projects may
have a disproportionate impact on the
Fund's share price.
-----------------------------------------------------------------------------------------
Repurchase Agreement Risk - A Fund may       Firstar U.S. Government Securities Fund
enter into repurchase agreements in which
banks, broker dealers and other financial    Stellar Treasury Fund
institutions sell securities to the Fund
and agree to repurchase them at a certain
time and price within one year.  A seller
may not repurchase the securities from
the Fund, which may result in the Fund
selling the security for less than the
agreed upon price.  Another risk of such
arrangements is that the seller may
default or file for bankruptcy.  That
could mean the Fund might have to wait
through lengthy court actions before
selling the securities.
-----------------------------------------------------------------------------------------
Bank Risk - Municipal obligations that a     Firstar Tax-Exempt Money Market Fund
Fund purchases may be backed by letters
of credit issued by banks and other          Stellar Tax-Free Money Market Fund
financial institutions.  Adverse
developments affecting banks could have a

Investment in Ohio Risk - Ohio's economy     Firstar Ohio Tax-Exempt Money Market Fund
is largely composed of manufacturing
which is concentrated in the automobile      Stellar Ohio Tax-Free Money Market Fund
sector and other durable goods.  The
exposure to these industries,
particularly the auto sector, leaves Ohio
vulnerable to an economic slowdown
associated with business cycles.
Furthermore, population growth, as in
many states around the Great Lakes, has
been stagnant.

A Fund's concentration in securities
issued by Ohio and its political
subdivisions provides a greater level of
risk than a fund whose assets are
diversified across numerous states and
municipal issuers.  The ability of Ohio
or its municipalities to meet their
obligations will depend on:  (1) the
availability of tax and other revenues;
(2) economic, political and demographic
conditions within the state; and (3) the
underlying fiscal condition of the state,
its counties and its municipalities.
-----------------------------------------------------------------------------------------
Credit Enhancement Risk - A Fund may         Firstar Ohio Tax-Exempt Money Market Fund
invest more than 25% of its total assets

Any bankruptcy, receivership, default or
change in the credit quality of the party

 Options Risk - A Fund may use options for    Firstar Strategic Income Fund
 hedging purposes only. The hedging           Stellar Strategic Income and
 strategy may not be successful if the         Stellar Funds
 portfolio manager is unable to accurately
 predict movements in the prices of
 individual securities held by the Fund or
 if the strategy does not correlate well
 with the Fund's investments. The use of
 options may produce a loss for a Fund,
 even when used only for hedging purposes
 and you could lose money because of a
 Fund's use of options.
--------------------------------------------------------------------------------
 Value Style Investing Risk - Different      Firstar Relative Value Fund
 types of equity securities tend to shift    Stellar Relative Value Fund
 in and out of favor depending on market
 and economic conditions, and the
 performance resulting from a Fund's
 "value" investment style may sometimes be
 lower than that of other types of equity
 funds, such as those focusing more
 exclusively on growth in earnings.
--------------------------------------------------------------------------------
 Industry Risk - A group of related stocks   Firstar Science & Technology Fund
 may decline in price due to industry        Stellar Science & Technology Fund
 specific developments.  Companies in the
 same or similar industries may share
 common characteristics and are more
 likely to react to industry specific
 market or economic developments.

 Science and Technology Concentration Risk   Firstar Science & Technology Fund
 - Science and technology related            Stellar Science & Technology Fund
 companies face special risks such as
 competitive pressures and technological
 obsolescence and may be subject to
 greater governmental regulation than many
 other industries.  Technology and
 technology related companies may be
 subject to short product cycles and
 aggressive pricing, which may increase
 their volatility. For example, their
 products or services may not prove
 commercially successful or may become
 obsolete quickly. The value of a Fund's
 shares may be susceptible to factors
 affecting the science and technology
 areas and to greater risk and market
 fluctuation than an investment in a fund
 that invests in a broader range of
 portfolio securities not concentrated in
 any particular industry. Furthermore,
 companies within the science and
 technology industries face greater risks
 of competition from new market entrances
 and increased research and development
 costs. Additionally, companies in these
 areas are dependent upon consumer and
 business acceptance as new technologies
 evolve.
--------------------------------------------------------------------------------
 IPO Risk - IPOs may have a magnified        Firstar Science & Technology Fund
 performance impact on a Fund with small     Stellar Science & Technology Fund
 asset base.  The impact of IPOs on a
 Fund's performance will decrease as a
 Fund's asset size increases.

 High Yield Bond Risk - High yield bonds     Firstar Global Equity Fund
 (generally referred to as junk bonds) are   Stellar International Equity Fund
 considered predominantly speculative by
 traditional investment standards.  The
 market value of these low-rated
 securities tends to be more sensitive to
 individual corporate developments and
 changes in interest rates and economic
 conditions than higher-rated securities.
 In addition, they generally present a
 higher degree of credit risk.  Issuers of
 low-rated securities are often highly
 leveraged, so their ability to repay
 their debt during an economic downturn or
 periods of rising interest rates may be
 impaired.
--------------------------------------------------------------------------------
 Underlying Funds Risk - A Fund's             Firstar Global Equity Fund
 performance directly relates to the          Stellar International Equity Fund
 performance of the funds in which it
 invests.  This investment strategy also
 subjects a Fund to additional expenses
 and certain tax consequences that would
 not exist if you invested in those funds
 directly.  By investing in a Fund, you
 bear not only the Fund's total operating
 expenses, but the operating expenses of
 the underlying funds as well.
--------------------------------------------------------------------------------
 When-Issued and Delayed Delivery             Stellar Treasury Fund
 Transaction Risk - If the seller chooses
 not to complete the transaction, the Fund
 could miss an advantageous price or
 yield. Another risk is that because
 settlement dates may be a month or more
 after entering into the transactions, the
 market value of the securities may have
 dropped from the agreed upon purchase
 price.

 Industrial Development Bond Concentration   Stellar Insured Tax-Free Bond Fund
 Risk - The Fund may invest more than 25%
 of its assets in industrial development
 bonds. The Fund does not invest that
 amount in the same facility or project.
 However, if the adviser chooses to
 concentrate those investments in the same
 industry or state, the shares of the Fund
 are likely to fluctuate in value more
 than those of a fund investing in a
 broader range of securities.
--------------------------------------------------------------------------------
 Convertible Securities Risk - Convertible   Firstar Balanced Income Fund
 securities frequently have speculative
 characteristics and may be acquired
 without regard to minimum quality
 ratings.  Convertible securities are
 subject to greater credit and interest
 rate risk than higher rated securities.

 Mid-Cap Index Risk - The Fund's             Firstar MidCap Index Fund
 investments follow the mid-cap portion of
 the U.S. stock market, as measured by
 the S&P MidCap 400 Index, during upturns
 as well as downturns. Because of its
 indexing strategy, the Fund cannot take
 steps to reduce market volatility or to
 lessen the effects of a declining market.

 Whenever mid-cap stocks underperform
 large- or small-cap stocks, the Fund may
 underperform funds that have exposure to
 those segments.  Further, the Fund will
 not necessarily dispose of a security in
 response to adverse events affecting the
 issuer of a security (such as adverse
 credit factors or failure to pay
 dividends) if disposal would not be
 consistent with the Fund's indexing
 strategy.

 The investment adviser may be required to
 sell securities if the issuer of the
 security is eliminated from the S&P
 MidCap 400 Index.  Such sales may result
 in lower prices or losses that may not
 have been incurred if the investment
 adviser did not have to sell the
 securities.

 The Fund's ability to duplicate the
 performance of the S&P MidCap 400 Index
 will depend to some extent on the size
 and timing of cash flows into and out of
 the Fund as well as the Fund's expenses.
--------------------------------------------------------------------------------
 Futures Risk - The Fund invests in futures   Firstar MidCap Index Fund
 contracts.  Futures contracts could cause
 the Fund to track the S&P MidCap 400
 Index less closely if they don't perform
 as expected.

      The proposed Reorganization is expected to benefit Stellar Fund
shareholders by, among other things:

(i)   offering a larger and more diverse group of mutual funds to all
shareholders;

(ii)  actually or potentially reducing overall expenses by the achievement of
economies of scale associated with a larger asset base;

(iii) offering an opportunity for better investment performance due to an
expanded equity research staff that can focus on the core products available;

(iv)  offering distribution channels that will have a better understanding of
the proprietary products offered by Firstar and will be better able to
communicate FIRMCO's investment style to existing and prospective shareholders,
thereby potentially increasing assets in the complex; and

(v)   allowing FIRMCO to effect portfolio transactions on more favorable terms.

      Description of the Reorganization Agreement. There are twelve separate
Stellar Funds. The Reorganization Agreement provides that substantially all of
the assets and liabilities of each of the six Stellar Funds identified in column
1 on Table III(A) below will be transferred to, and acquired by, one of the six
Existing Firstar Funds identified in column 2 on Table III(A) below, in exchange
for full and fractional shares issued by such Existing Firstar Fund. The
Reorganization Agreement further provides that substantially all of the assets
and liabilities of each of the Stellar Funds identified in column 1 on Table
III(B) below will be transferred to, and acquired by, one of the newly-organized
Shell Firstar Funds identified in column 2 on Table III(B) below, in exchange
for full and fractional shares issued by such Shell Firstar Funds. In the
tables, opposite the name of each Stellar Fund is the name of the Corresponding
Firstar Fund to which such Stellar Fund will transfer substantially all of its
assets and liabilities and that will issue shares to such Stellar Fund in
consideration of such transfer. The Firstar Fund Shares issued by each Firstar
Fund to its corresponding Stellar Fund will have the same aggregate dollar value
as the aggregate dollar value of the shares of such Stellar Fund immediately
prior to the effective time of the Reorganization with respect to such Fund.

     Immediately after the effective time of the Reorganization, each Stellar
Fund will distribute to its shareholders the Firstar Fund Shares received in the
Reorganization in liquidation of the Stellar Fund.  Each shareholder of record
of a particular Stellar Fund at the effective time of the Reorganization will
receive shares of the designated class of its Corresponding Firstar Fund with
the same aggregate dollar value of the shares such shareholder held in such
Stellar Fund prior to the effective time of the Reorganization and will receive
any unpaid dividends or distributions declared before the effective time of the
Reorganization with respect to such Stellar Fund.

     Firstar will establish an account for each former shareholder of the
Stellar Funds that will reflect the number and class of Firstar Fund Shares
distributed to that shareholder.  The Firstar Fund Shares issued in the
Reorganization will be in uncertificated form.

     Please note that a vote for or against the Reorganization Agreement
includes a vote for or against the reorganization of Stellar into Firstar. If
the Reorganization Agreement is approved and the transactions contemplated
thereby are consummated, Stellar will transfer substantially all of its assets
and liabilities as of the effective time of the Reorganization, all outstanding
shares of the Stellar Funds will be redeemed and cancelled in exchange for
Firstar Fund Shares of the Firstar Funds, and Stellar will wind up its affairs
and apply to be deregistered as an investment company under the 1940 Act and
thereafter terminate under Massachusetts law.

     The Reorganization is subject to a number of conditions, including approval
of the Reorganization Agreement and the related matters described in this
Proxy/Prospectus by a majority of the outstanding shares of each Stellar Fund;
the receipt of certain legal opinions described in the Reorganization Agreement
(which include an opinion of Firstar's counsel addressed to Stellar indicating
that the Firstar Fund Shares issued in the Reorganization will be validly
issued, fully paid and non-assessable); the receipt of certain certificates from
the parties concerning the continuing accuracy of the representations and
warranties in the Reorganization

                                      -36-
<PAGE>

Agreement; the receipt of any necessary exemptive relief requested from the SEC
or its staff with respect to Section 17(a) of the 1940 Act; and the parties'
performance in all material respects of their respective covenants and
undertakings as described in the Reorganization Agreement.

     The Reorganization Agreement also provides that FIRMCO or an affiliate has
agreed to pay all expenses associated with the Reorganization.  The
Reorganization Agreement also provides, among other things, that the
Reorganization may be terminated at any time upon the mutual consent of both
Stellar and Firstar, or by either Firstar or Stellar under certain conditions;
and that officers of Firstar and of Stellar may amend the Reorganization
Agreement as authorized by their respective Boards of Directors or Trustees, as
the case may be.

     As previously noted, the Mercantile reorganization and the Select
reorganization are expected to occur at the same time as the Reorganization. In
connection with the Mercantile Reorganization, certain of the Mercantile
investment portfolios will be reorganized into the same Firstar Funds as certain
of the Stellar Funds. In particular, (1) the Mercantile Treasury Money Market
Portfolio together with the Stellar Treasury Fund will be reorganized into the
Firstar U.S. Treasury Money Market Fund; (2) the Mercantile Tax-Exempt Money
Market Portfolio together with the Stellar Tax-Free Money Market Fund will be
reorganized into the Firstar Tax-Exempt Money Market Fund; (3) the Mercantile
U.S. Government Securities Portfolio together with the Stellar U.S. Government
Income Fund will be reorganized into Firstar U.S. Government Securities Fund and
(4) the Mercantile National Municipal Bond Portfolio together with the Stellar
Insured Tax-Free Bond Fund will be reorganized into the Firstar National
Municipal Bond Fund. If the Reorganization Agreement is approved by Stellar
shareholders at the Special Meeting, it is expected that the Reorganization will
be completed whether or not the Mercantile reorganization and Select
reorganization are consummated.

     Stellar Board Consideration.  At a meeting held on April 20, 2000, the
Board of Trustees of Stellar was advised that FIRMCO was considering
recommending a consolidation of Stellar with Firstar.  The Stellar Board then
met again on June 7, July 12, and July 20, 2000 to consider the Reorganization
proposal offered by management of Firstar, FIRMCO and its affiliates.  In
preparation for the June 7, 2000 meeting, each of the Trustees of Stellar was
provided with detailed information about the Reorganization, Firstar and FIRMCO.
These materials summarized the principal terms and conditions of the
Reorganization, including the intention that the Reorganization be consummated
on a tax-free basis for each Stellar Fund and its shareholders.  In addition,
the Stellar Trustees received comparative information about the Stellar Funds
and the Corresponding Firstar Funds, including information concerning, but not
limited to, the following matters:  (1) investment objectives and policies; (2)
advisory, distribution and servicing arrangements; (3) fund expenses (with and
without giving effect to current expense limitations), including pro forma
expenses, relative to peer groups; and (4) performance, including performance
relative to peer groups or comparable indices for the Firstar Funds.  The
Stellar Board also was provided with information about FIRMCO and its investment
advisory organization, including the individuals or teams of individuals with
responsibility for managing each Firstar Fund.

                                      -37-
<PAGE>

     The Reorganization was unanimously approved by the Stellar Board of
Trustees on June 7, 2000, subject to the Board's receipt from FIRMCO of
additional information on certain aspects of the Reorganization.  This
additional information was received and considered by the Stellar Board on July
12 and on July 20, 2000, the Board of Trustees of Stellar unanimously ratified
the actions it had taken on June 7, 2000 approving the Reorganization.

     During its deliberations, Stellar's Board of Trustees (with the advice and
assistance of its counsel) reviewed, among other things:  (1) the potential
effect of the Reorganization on the shareholders of the Stellar Funds; (2) the
capabilities, practices and resources of FIRMCO; (3) the investment advisory and
other fees paid by the Firstar Funds, and the historical and projected expense
ratios of the Firstar Funds as compared with those of the Stellar Funds and
industry peer groups; (4) the investment objectives, policies and limitations of
the Firstar Funds and their relative compatibility with those of the Stellar
Funds; (5) the historical investment performance records of the Stellar Funds
and the Firstar Funds, relative to each other and to peer groups or comparable
indices; (6) the shareholder services offered by Firstar; (7) the terms and
conditions of the Reorganization Agreement; (8) the anticipated tax consequences
of the Reorganization for the respective Stellar Funds and their shareholders;
and (9) the number of investment portfolio options that would be available to
shareholders after the Reorganization.  The Stellar Board also considered
FIRMCO's belief that the Reorganization would eliminate certain duplicative
shareholder costs and market overlap, facilitate consolidation of FIRMCO's
managerial resources and enhance generally operational efficiencies and focus
with respect to the mutual funds advised by FIRMCO.

     The Stellar Trustees also noted that the per share annualized total
operating expense ratios for certain of the classes of certain of the Firstar
Funds after the Reorganization, taking into account voluntary fee waivers, would
be higher than those of the corresponding Stellar Funds before the
Reorganization.  See "Fee Tables - Table I-C - Total Expense Information" and
Appendix II for more information.  The Stellar Trustees also noted that FIRMCO
or an affiliate would assume all customary expenses associated with the
Reorganization and that FIRMCO would commit to waive fees and/or reimburse
expenses as needed to insure that until March 1, 2001 the Firstar Funds' total
operating expense ratios will not exceed the pro forma after-waiver expenses
shown in Table I-C.

     After consideration of the foregoing and other factors, the Stellar
Trustees unanimously determined that the Reorganization was in the best interest
of the shareholders of each Stellar Fund, and that the interests of the existing
shareholders of each Stellar Fund would not be diluted as a result of such
Reorganization.

     Capitalization. The following table sets forth, as of April 30, 2000 (the
end of Firstar's semi-annual period):  (1) the capitalization of each of the
Stellar Funds; (2) the capitalization of each of their Corresponding Firstar
Funds; and (3) the pro forma capitalization of each of the Corresponding Firstar
Funds as adjusted to give effect to the Reorganization.  With respect to the
Stellar Treasury Fund, Stellar Tax-Free Money Market Fund, Stellar U.S.
Government Income Fund and Stellar Insured Tax-Free Bond Fund, the table also
sets forth the capitalization of the Mercantile Fund which will, if the
conditions described in the reorganization agreement between Mercantile and
Firstar are timely met, simultaneously be reorganized into the Corresponding

                                      -38-
<PAGE>

Firstar Fund of such Stellar Fund and the pro forma capitalization of such
Corresponding Firstar Fund as adjusted to give effect to both the Reorganization
and the Mercantile reorganization.

     The capitalization of each Fund is likely to be different at the effective
time of the Reorganization as a result of daily share purchase and redemption
activity in the Funds as well as the effects of the other ongoing operations of
the respective Funds prior to the closing of the Reorganization.

     The Firstar Ohio Tax-Free Money Market Fund, Firstar Strategic Income Fund,
Firstar Large Cap Growth Fund, Firstar Relative Value Fund, Firstar Science &
Technology Fund, and Firstar Global Equity Fund have not yet commenced
operations but will do so at the time the Reorganization occurs.

1. The table below reflects the capitalization as of April 30, 2000, and pro
   forma capitalization for the combination of the Stellar Treasury Fund with
   the Firstar U.S. Treasury Money Market Fund. The table provides pro forma
   capitalization information for two different scenarios: (a) the combination
   of the Stellar Treasury Fund with the Firstar U.S. Treasury Money Market Fund
   (Pro forma Combined Fund = Fund A + Fund C) and (b) the combination of the
   Stellar Treasury Fund, the Mercantile Treasury Money Market Portfolio and the
   Firstar U.S. Treasury Money Market Fund (Pro forma Combined Fund = Fund A +
   Fund B + Fund C).

     Federal Income Tax Considerations.  Each Firstar Fund and each Stellar Fund
intends to qualify as of the effective time of the Reorganization as a separate
"regulated investment company" under the Internal Revenue Code of 1986, as
amended (the "Code").  Accordingly, each Stellar Fund and each Corresponding
Firstar Fund has been, and expects to continue to be, relieved of federal income
tax liability.

     Consummation of the Reorganization with respect to each Stellar Fund and
its Corresponding Firstar Fund is subject to the condition that Stellar and
Firstar receive an opinion from Drinker Biddle & Reath LLP substantially to the
effect that, for federal income tax purposes:  (i) the transfer of substantially
all of the assets and liabilities of a Stellar Fund to its Corresponding Firstar
Fund in exchange for the Firstar Fund Shares issued by such Corresponding
Firstar Fund, and the distribution of those Firstar Fund Shares to shareholders
of the Stellar Fund, will consist of twelve "reorganizations" within the meaning
of Section 368(a) of the Code, and each Stellar Fund and its Corresponding
Firstar Fund will each be a "party to a reorganization" within the meaning of
Section 368(b) of the Code in respect of the Reorganization; (ii) no gain or
loss will be recognized by any Stellar Fund upon the transfer of its assets and
liabilities to its Corresponding Firstar Fund solely in exchange for Firstar
Fund Shares of the Corresponding Firstar Fund; (iii) no gain or loss will be
recognized by each Firstar Fund upon the receipt of the assets and assumption of
liabilities of its Corresponding Stellar Fund solely in exchange for the Firstar
Fund Shares; (iv) the basis of each Stellar Fund's assets received by the
Corresponding Firstar Fund pursuant to the Reorganization will be the same as
the basis of those assets in the hands of such Stellar Fund immediately prior to
the Reorganization; (v) the holding period of each Stellar Fund's assets in the
hands of its Corresponding Firstar Fund will include the period for which such
assets have been held by such Stellar Fund; (vi) no gain or loss will be
recognized by any Stellar Fund on the distribution to its shareholders of the
Firstar Fund Shares of its Corresponding Firstar Fund; (vii) no gain or loss
will be recognized by the shareholders of any Stellar Fund upon their receipt of
the Firstar Fund Shares in exchange for such shareholders' shares of the Stellar
Fund; (viii) the basis of the Firstar Fund Shares received by the shareholders
of each Stellar Fund will be the same as the basis of the Stellar Fund Shares
surrendered by such shareholders pursuant to the Reorganization; (ix) the
holding period for the Firstar Fund Shares received by each Stellar Fund
shareholder will include

                                      -53-
<PAGE>

the period during which such shareholder held the Stellar Fund Shares
surrendered in exchange therefor, provided that such Stellar Fund shares are
held as a capital asset in the hands of such Stellar Fund shareholder on the
date of the exchange; and (x) each Firstar Fund will succeed to and take into
account the tax attributes described in Section 381 (c) of the Code of the
Stellar Fund as of the effective time of the Reorganization with respect to the
Stellar Funds, subject to the conditions and limitations specified in the Code.
Shareholders of the Stellar Funds should note, however, that the sale of
securities by the Stellar Funds prior to the effective time of the
Reorganization, whether in the ordinary course of business or in anticipation of
the Reorganization, could increase the amount of the taxable capital gains
distribution made prior to the Reorganization.

     Firstar and Stellar have not sought, and will not seek, a private ruling
from the Internal Revenue Service ("IRS") with respect to the federal income tax
consequences of the Reorganization. The opinion of Drinker Biddle & Reath LLP
with respect to the federal income tax consequences of the Reorganization is not
binding on the IRS and does not preclude the IRS from adopting a contrary
position. Shareholders should consult their own advisers concerning the
potential tax consequences of the Reorganization to them, including any
applicable foreign, state or local income tax consequences.

                 COMPARISON OF STELLAR FUNDS AND FIRSTAR FUNDS

     Investment Objectives and Policies. The investment objectives, policies and
restrictions of each of the Stellar Ohio Tax-Free Money Market, Strategic
Income, Growth Equity, Relative Value, Science & Technology and International
Equity Funds are, in each case, substantially the same as those of its
respective corresponding Shell Firstar Fund. Each of these Shell Firstar Funds
is being created to acquire the assets and liabilities and continue the business
of its respective corresponding Continuing Stellar Fund. The investment
objectives, policies and restrictions of each of the Stellar Tax-Free Money
Market, U.S. Government Income, Insured Tax-Free Bond, Stellar and Capital
Appreciation Funds, are, in general, similar to those of its respective
corresponding Existing Firstar Fund. They are summarized in Appendix III. In
addition, it is expected that upon consummation of the reorganization of the
Stellar Treasury Fund and Mercantile Treasury Money Market Portfolio into the
Firstar U.S. Treasury Money Market Fund, the Firstar U.S. Treasury Money Market
Fund will adopt the investment objective and non-fundamental investment policies
and restrictions of the Stellar Treasury Fund, but the Firstar U.S. Treasury
Money Market Fund will retain its current fundamental investment limitations
which are similar, but not identical, to the Stellar Treasury Fund's fundamental
investment limitations.

     There are, however, certain differences in the types of securities in which
each of the Reorganizing Stellar Funds may invest and the types of securities in
which its Corresponding Firstar Fund may invest, as well as differences in
certain investment policies of the Funds.  A discussion of some of the more
significant differences between some of the Funds follows.

     Reorganizing Money Market Funds. The Stellar Money Market Funds and the
     -------------------------------
Firstar Money Market Funds are all subject to the general restrictions and
limitations of Rule 2a-7 under the 1940 Act.  However, there are differences
between the investment policies and restrictions of the Stellar Money Market
Funds and their Corresponding Firstar Funds.  Although it is expected that the
Firstar U.S. Treasury Money Market Fund will adopt the investment objectives and
non-fundamental investment policies and restrictions of

                                      -54-
<PAGE>

the Stellar Treasury Fund, the Firstar U.S. Treasury Money Market Fund will
retain its fundamental investment limitations. Accordingly, there are some
differences between the Funds. For example, the Stellar Treasury Fund differs
from the Firstar U.S. Treasury Money Market Fund in that the Firstar U.S.
Treasury Money Market Fund has fundamental policies permitting the Fund to
borrow up to 10% of the value of its net assets and lend up to 30% of its net
assets, while the Stellar Treasury Fund has fundamental policies permitting it
to borrow up to 33-1/3% of its net assets and prohibiting it from engaging in
securities lending. The Stellar Tax-Free Money Market Fund differs from its
Corresponding Firstar Fund in that the Stellar Tax-Free Money Market Fund may
invest more than 25% of its total assets (i.e., concentrate) in securities
credit-enhanced by banks while the Firstar Tax-Exempt Money Market Fund may
invest more than 25% of its assets in municipal obligations covered by insurance
policies. In addition, the Stellar Tax-Free Money Market Fund, but not the
Firstar Tax-Exempt Money Market Fund, may invest in municipal leases and
repurchase agreements. The Firstar Tax-Exempt Money Market Fund, unlike the
Stellar Tax-Free Money Market Fund, may invest more than 25% of its total assets
in municipal obligations, the issuers of which are located in the same state or
the interest on which is paid solely from revenues of similar projects if such
investment is deemed necessary or appropriate by the adviser.

     Reorganizing Bond Funds. The Stellar U.S. Government Income Fund and its
     -----------------------
Corresponding Firstar Fund, the Firstar U.S. Government Securities Fund, have
similar investment programs, except that the Stellar U.S. Government Income Fund
may invest in investment grade debt securities of foreign issuers, while its
Corresponding Firstar Fund may not.  The Stellar Insured Tax-Free Bond Fund and
its Corresponding Firstar Fund, the Firstar National Municipal Bond Fund, both
invest at least 80% of their total assets in municipal securities that pay
interest that is exempt from federal income tax.  At least 65% of the value of
the Stellar Insured Tax-Free Bond Fund's assets are invested in intermediate- to
long-term, investment grade municipal securities that are insured as to timely
payment while the Firstar National Municipal Bond Fund is not subject to this
requirement.  In addition, while the Stellar Insured Tax-Free Bond Fund has no
target average weighted maturity, the Firstar National Municipal Bond fund will
have an average weighted maturity longer than 10 years.

     Reorganizing Equity Funds. The Stellar Fund invests no more than 50% of
     -------------------------
its net assets in each of the following:  domestic equity securities, domestic
fixed-income securities, international securities, real estate securities and
short-term securities.  Its Corresponding Firstar Fund, the Firstar Balanced
Income Fund, typically invests 50% (but no less than 20% and no more than 60%)
of its assets in equity securities and 50% (but no less than 40%) of its assets
in fixed income securities.  In addition, the equity securities the Firstar
Balanced Income Fund invests in have market capitalizations of over $750
million, while the Stellar Fund may invest in equity securities of small, medium
or large companies.  The Stellar Capital Appreciation Fund and its Corresponding
Firstar Fund, the Firstar MidCap Index Fund, are similar in that both seek to
achieve their investment objectives by investing a substantial portion of their
net assets in the equity securities of U.S. companies with mid-level market
capitalizations.  However, the Stellar Capital Appreciation Fund invests at
least 50% of its total assets in companies whose market

                                      -55-
<PAGE>

capitalizations range from $200 million to $10 billion and whose shares are
traded on NASDAQ or on the New York or American Stock Exchanges, and in
selecting these securities, the investment advisor employs automated
quantitative measurement techniques. The Firstar MidCap Index Fund attempts to
replicate the performance of the S&P MidCap 400 Index by investing at least 80%
of its net assets in domestic companies included in the index with market
capitalization between $148 million and $13 billion.

     The investment objectives, strategies and policies of the Stellar Funds and
Firstar Funds are more fully discussed in Appendix III.  Additional information
about the investment policies and restrictions of the Stellar Funds and Firstar
Funds is included in their respective prospectuses and statements of additional
information, which have been incorporated herein by reference.

     Investment Advisory Services. FIRMCO serves as investment adviser to the
Firstar Funds and Stellar Funds and will continue to serve as investment adviser
to the Firstar Funds upon consummation of the Reorganization.

     The following table shows the contractual investment advisory fees for each
Stellar Fund and its Corresponding Firstar Fund. For the Stellar Funds, the
table also shows the respective investment advisory fee rates paid to the
investment advisor and sub-advisor after taking into account voluntary fee
waivers. For the Firstar Funds, pro forma advisory fees are calculated based
upon contractual advisory fees then reduced by expected waivers to achieve the
desired expense ratio. The fees for the Stellar Funds are as of April 30, 2000.
The fees for the Firstar Funds (both before and after waivers) represent the pro
forma annualized advisory fees based upon fee arrangements that will be in place
upon consummation of the Reorganization.

          Sales Loads, Distribution Arrangements and Shareholder Servicing
          Arrangements for Stellar

          Class A Shares. Each Stellar Fund, other than the Stellar Treasury
          --------------
     Fund, Stellar Tax-Free Money Market Fund and Stellar Ohio Tax-Free Money
     Market Fund, offers Class A Shares. Class A Shares of each Stellar Fund,

Money Market Fund and Stellar Ohio Tax-Free Money Market Fund, charge a front-
end sales load at the time of purchase. The maximum front-end sales load charged
for Class A Shares is 4.00% for bond funds, 5.50% for equity funds other than
the International Equity Fund and 1.50% for the International Equity Fund. A
chart showing the breakpoints for sales charges for Class A Shares is set forth
in Appendix IV. Sales load reduction and waiver categories, which differ in
certain respects from those applicable to Retail A Shares of the Corresponding
Firstar Funds, are described in Appendix IV.

     Stellar has adopted a Distribution Plan for Class A Shares of the Stellar
Funds. Stellar has also adopted a Shareholder Servicing Plan for Class A Shares
of the Stellar Funds. Under these plans, Class A Shares pay distribution fees of
up to an annual rate of 0.25% of the average daily net asset value of the shares
to the Distributor and shareholder servicing fees of up to 0.25% of the average
daily net asset value of the shares, to shareholder servicing organizations.
Currently, Stellar limits the shareholder servicing fee to an annual rate of
0.16% of average daily net assets, but this waiver can be modified or terminated
at any time. Payments to the Distributor are used to finance activities that
promote the sale of the Funds' shares, such as advertising, printing and mailing
prospectuses to persons other than current shareholders, printing and mailing
sales literature, and compensating underwriters, dealers and sales personnel.
The Shareholder Servicing Plan permits the payment of fees to Firstar Bank, N.A.
and, indirectly, to financial institutions to cause services to be provided to
shareholders by a representative who has knowledge of the shareholder's
particular circumstances. These services may include, among other things,
assisting customers in processing purchase, exchange and redemption requests,
establishing and maintaining shareholder accounts and records, answering routine
client inquiries and assisting clients in changing account designations.

     Class B Shares.  Each Stellar Fund, other than the Stellar Treasury Fund,
     --------------
Stellar Tax-Free Money Market Fund, Stellar Ohio Tax-Free Money Market Fund and
Stellar International Equity Fund, offers Class B Shares.  Class B Shares are
sold at net asset value without imposition of a front-end sales load at the time
of purchase.  However, there is a maximum 5% contingent deferred sales charge
(CDSC) assessed on Class B Shares that are redeemed within one year of purchase,
declining to 1% in the sixth year and eliminated thereafter.  Retail B Shares of
the Firstar Funds received in exchange for Class B Shares of the Stellar Funds
will be subject to the CDSC.  In all cases, former holders of Class B Shares of
the Stellar Funds will be credited for the period from the original date of
purchase of the Class B Shares for the purpose of determining the amount of
CDSC, if any.

     Stellar has adopted a Distribution Plan pursuant to which Stellar's
distributor is entitled to receive fees from (1) the Stellar Science &
Technology Fund, Stellar Fund, Stellar Capital Appreciation Fund and Stellar
Insured Tax-Free Bond Fund at the annual rate of up to 0.75% of the average
aggregate net asset value of shares of the Funds held during the month, and (2)
the Class B Shares of the other Funds at the annual rate of up to 0.25% of the
average aggregate net asset value of shares of the Funds held during the month.
Payments to the Distributor are used to finance activities that promote the sale
of the Funds' shares, such as advertising, printing and mailing prospectuses to
persons other than current shareholders, printing and mailing sales literature,
and compensating underwriters, dealers and sales personnel.

     Shareholder Transactions and Policies

     The Stellar Funds and the Corresponding Firstar Funds offer generally
similar shareholder services and transactions.  There are, however, some
differences in the shareholder services and transactions of the Stellar Funds
and the Corresponding Firstar Funds.  For example, Firstar Funds offer a program
called ConvertiFund which lets investors automatically exchange shares of one
account for shares of another account on a regular basis, as long as the shares
are Retail A or Retail B Shares.  Shareholders of Firstar Funds are also able to
purchase (other than initial purchases), exchange and redeem shares via the
Internet.  For a more detailed comparison of shareholder transactions and
policies, see Appendix IV.

     Fees and Expenses

     With respect to two out of the eight Stellar Funds in which holders of
Class A Shares of such Stellar Fund will receive Retail A Shares of the
Corresponding Firstar Fund and with respect to six out of the eight Stellar
Funds in which holders of Class B Shares of such Stellar Fund will receive
Retail B Shares of the Corresponding Firstar Fund, the Corresponding Firstar
Fund will have total operating expense ratios with respect to such class (after
fee waivers) that are higher than that of the corresponding class of the
corresponding Stellar Fund.  However, all Stellar Class A and Class B
shareholders who will be receiving Institutional Shares of the Corresponding
Firstar Fund in the Reorganization will have total operating expense ratios
(after fee waivers) that are lower after the Reorganization.  In addition, with

shareholders will be receiving Retail B Shares of the Corresponding Firstar
Fund, the Corresponding Firstar Fund will have total operating expense ratios
with respect to such class (after fee waivers) that are lower than that of the
corresponding class of the corresponding Stellar Fund.  Stellar Class A
shareholders will have total operating expense ratios (after fee waivers) that
are the same after the Reorganization with respect to two out of the eight
Stellar Funds in which Class A shareholders of such Stellar Fund will receive
Retail A Shares of the Corresponding Firstar Fund.

     All Stellar Class C shareholders will have total operating expense ratios
(after fee waivers) that are lower after the Reorganization.  Stellar Class Y
shareholders will have total operating expense ratios (after fee waivers) that
are lower after the Reorganization with respect to three out of five Stellar
Funds and the same with respect to the remaining two Stellar Funds.
Specifically, Class Y shareholders of the Stellar Treasury Fund, Relative Value
Fund and Stellar Fund will have lower total operating expense ratios (after fee
waivers) after the Reorganization than what they had while invested in the
relevant Stellar Fund prior to the Reorganization, and Class Y shareholders of
the Stellar Growth Equity Fund and Stellar Science & Technology Fund will have
the same total operating expense ratios (after fee waivers) after the
Reorganization as what they had while invested in the relevant Stellar Fund
prior to the Reorganization.

     Fee waivers are subject to termination.  For a more detailed summary of
fees and expenses, see "Fee Tables" and Appendix II.

     Performance. The total returns of the Firstar Funds are competitive with
the Stellar Funds. For a comparison of the total return performance of the
Reorganizing Stellar Funds with the Existing Firstar Fund, see Appendix V. See
also Appendix VI for Management Discussion of Firstar Fund Performance.

     Share Structure. Both Stellar and Firstar are registered as open-end
management investment companies under the 1940 Act. Currently, Stellar offers
twelve funds. Firstar currently offers twenty-one funds and will offer thirty-
six funds immediately after the Reorganization (assuming the Mercantile and
Select reorganizations are also consummated).

     Stellar is a Massachusetts business trust established under a Declaration
of Trust dated January 23, 1989.  Stellar was organized under the name "Value
Plus Funds," but its name was changed on March 29, 1989 to "Losantiville Funds."
On May 1, 1993, the name of Stellar was changed again to "Star Funds."  On
November 20, 1998, Star Banc Corporation, the parent company of Star Bank, N.A.,
Stellar's former investment advisor, merged with Firstar Corporation.  After the
merger, Star Bank, N.A. changed its name to Firstar Bank, N.A.  Effective March
1, 1999, the Board of Trustees of Stellar approved changing Stellar's name to
"Firstar Stellar Funds."

     Stellar's Declaration of Trust authorizes the Board of Trustees to divide
the beneficial interest in Stellar into an unlimited number of shares (with no
par value) and to divide the shares into one or more classes.  Shares of Stellar
may be issued in series and shares of any series will constitute units of
beneficial interest in Stellar specifically allocated to such series.  Each
share of Stellar represents an equal proportionate interest in the related
investment portfolio with other shares of the same class, none having priority
or preference over another.  Shares of Stellar are entitled to one vote for each
full share held and fractional votes for fractional shares held.  All shares of
all classes of each Stellar Fund have equal voting rights.  However, matters
affecting only one particular Fund or class can be voted on only by shareholders
in that fund or class.  There is no cumulative voting in the election of
Trustees for the Stellar Funds.

     Firstar was organized as a Wisconsin Corporation on February 15, 1988.  The
company, formerly known as Portico Funds, Inc., changed its name to Firstar
Funds effective February 1, 1998.  Firstar's Articles of Incorporation authorize
the Board of Directors to issue full and fractional shares of capital stock
($0.0001 par value per share) and to classify and reclassify any particular
class of shares into one or more additional series of shares.  Shares of the
Firstar Funds are entitled to one vote for each full share held and fractional
votes for fractional shares held.

     Shareholders of Firstar Funds will vote together in the aggregate and not
separately on a fund-by-fund basis, except as otherwise required by law or when
the Board of Directors determines that the matter to be voted upon affects only
the interests of the shareholders of a particular class or a particular series
within a class.  On any matter submitted to the vote of shareholders which only
pertains to agreements, liabilities or expenses applicable to one series of a
Fund (such as a Distribution and Service Plan applicable to Retail A or B
Shares) but not the other series of the same Fund, only the affected series will
be entitled to vote.  There is no cumulative voting with respect to Firstar
Funds shares.

     Additional information concerning the attributes of the shares issued by
Stellar and Firstar is included in their respective prospectuses, which are
incorporated herein by reference.  Information about the dividend and
distribution policies of both the Stellar Funds and the Firstar Funds can be
found in Appendix IV.

     Comparison of Trust and Corporate Structure.  Stellar is organized as a
Massachusetts business trust.  Firstar is organized as a Wisconsin corporation.
Although the rights of a holder of a share of beneficial interest of a
Massachusetts business trust vary in certain respects from the rights of a
shareholder of a Wisconsin corporation, the attributes of a share of beneficial
interest

                                      -64-
<PAGE>

are comparable to those of a share of common stock, i.e., shares of
both are entitled to one vote per share held and fractional votes for fractional
shares held, and will vote in the aggregate and not by portfolio or class except
as otherwise required by law or when class voting is permitted by its Board.

     It should be noted that under Wisconsin law, Firstar shareholders have no
personal liability for Firstar's acts or obligations.  By contrast, under
certain circumstances, Stellar shareholders may be held personally liable under
Massachusetts law for acts or obligations of the Trust.  To protect
shareholders, Stellar has provisions in its Declaration of Trust that endeavor
to protect shareholders from such liability.  Thus, the risk of an interest
holder incurring a financial loss on account of interest holder liability is
limited to circumstances in which the Trust itself is unable to meet its
obligations.

                                VOTING MATTERS

     General Information.  The Board of Trustees of Stellar is furnishing this
Proxy/Prospectus in connection with the solicitation of proxies for the Special
Meeting.  It is expected that the solicitation of proxies will be primarily by
mail.  Officers and service contractors of Stellar and Firstar may also solicit
proxies by telephone or otherwise.  In this connection, Stellar has retained ADP
Proxy Services ("ADP") and D.F. King & Co., Inc. ("D.F. King") to assist in the
solicitation of proxies for the Reorganization.  Shareholders may vote (1) by
mail, by marking, signing, dating and returning the enclosed Proxy Ballot(s) in
the enclosed postage-paid envelope, (2) by touch-tone telephone voting, or (3)
by on-line voting.  Any shareholder giving a proxy may revoke it at any time
before it is exercised by submitting to Stellar a written notice of revocation
or a subsequently executed proxy or by attending the Special Meeting and voting
in person.  As the Special Meeting date approaches, certain shareholders of each
Fund may receive a telephone call from a representative of D.F. King if their
votes have not yet been received.  Authorization to permit ADP or D.F. King to
execute proxies may be obtained by telephonic or electronically transmitted
instructions from shareholders of each Fund.  Proxies that are obtained
telephonically will be recorded in accordance with the procedures set forth
below.  The Trustees believe 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 D.F. King
representative is required to ask for each shareholder's full name, address,
social security or employer identification number, title (if the shareholder is
authorized to act on behalf of an entity, such as a corporation), and the number
of shares owned, and to confirm that the shareholder has received the proxy
materials in the mail.  If the information solicited agrees with the information
provided to D.F. King, then the D.F. King representative has the responsibility
to explain the process, read the Proposals on the proxy card, and ask for the
shareholder's instructions on the Proposals.  The D.F. King representative,
although he or she is 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 on the proxy statement.  D.F. King will record the
shareholder's instructions on the card.  Within 72 hours, the shareholder will
be sent a letter or mailgram to

                                      -65-
<PAGE>

confirm his or her vote and asking the shareholder to call D.F. King immediately
if his or her instructions are not correctly reflected in the confirmation.

          Any expenses incurred as a result of hiring ADP, D.F. King or any
other proxy solicitation agent will be borne by FIRMCO or its affiliates.  It is
anticipated that the cost associated with using proxy solicitation agents will
be approximately $________.

          Only shareholders of record at the close of business on September 15,
2000 will be entitled to vote at the Special Meeting.  On that date, the
following Stellar Shares were outstanding and entitled to be voted:

          Each whole and fractional share of a Stellar Fund is entitled to a
whole or fractional vote, as the case may be.

          If an accompanying proxy is executed and returned in time for the
Special Meeting, the shares covered thereby will be voted in accordance with the
proxy on all matters that may properly come before the Special Meeting.

     Shareholder and Board Approvals.  The Reorganization Agreement is being
submitted for approval at the Special Meeting by Stellar's shareholders pursuant
to Stellar's Amended and Restated Declaration of Trust and By-Laws, and was
unanimously approved by Stellar's Board of Trustees at a meeting held on July
20, 2000.  The Reorganization Agreement must be approved by the holders of a
majority of the outstanding shares of each Stellar Fund.  A vote for the
Reorganization Agreement includes a vote for the reorganization of Stellar;
conversely, a vote against the Reorganization Agreement is a vote against the
reorganization of Stellar.

          The Reorganization Agreement provides that in the event the
Reorganization Agreement is approved with respect to less than all of the
Stellar Funds, the failure of a Stellar

                                      -66-
<PAGE>

Fund to consummate the transactions contemplated by the Reorganization Agreement
shall not affect the consummation or validity of the Reorganization with respect
to any other Stellar Fund.

          With respect to the approval of the Reorganization Agreement, the term
"majority of the outstanding shares" means more than 50% of the outstanding
shares of each particular Stellar Fund.  The vote of the shareholders of the
Firstar Funds is not being solicited, since their approval or consent is not
necessary for the Reorganization.

     Principal Shareholders.  As of September 15, 2000, the officers and
Trustees of Stellar as a group owned or controlled less than 1% of each Stellar
Fund's outstanding shares.  As of September 15, 2000, the officers and directors
of Firstar as a group owned or controlled less than 1% of each Firstar Fund's
outstanding shares.  Table VI(A) shows the name, address and share ownership of
each person known to Stellar to have ownership with respect to 5% or more of a
Stellar Fund as of August September 15, 2000.  Table VI(B) shows the name,
address and share ownership of each person known to Firstar to have ownership,
as of September 15, 2000, with respect to 5% or more of a class of a Mercantile
Fund that is expected to reorganize into a Firstar Fund along with a Stellar
Fund.  Table VI(C) shows the name, address and share ownership of each person
known to Firstar to have ownership with respect to 5% or more of a class of a
Firstar Fund as of September 15, 2000.  The type of ownership of each entry
listed on Tables VI(A), VI(B) and VI(C) is record ownership.

</TABLE>

          For purposes of the 1940 Act, any person who owns directly or through
one or more controlled companies more than 25% of the voting securities of a
company is presumed to "control" such company.  Accordingly, to the extent that
a shareholder identified in the foregoing table is identified as the beneficial
holder of more than 25% of a class, or is identified as the holder of record of
more than 25% of a class and has voting and/or investment power, such
shareholder may be presumed to control such class.

          Firstar and Stellar have been advised by Firstar Bank, N.A., an
affiliate of FIRMCO, that, with respect to the shares of each Stellar Fund over
which Firstar Bank, N.A. has voting power, such shares may be voted by Firstar
Bank, N.A. itself in its capacity as fiduciary.

     Quorum.  In the event that a quorum is not present at the Special Meeting,
or in the event that a quorum is present at the Special Meeting but sufficient
votes to approve the Reorganization Agreement are not received by Stellar or by
one or more of the Stellar Funds, one or more adjournment(s) may be proposed to
permit further solicitation of proxies.  Any adjourned session or sessions may
be held after the date set for the original Special Meeting without notice
except announcement at the Special Meeting.  Any such adjournment(s) will
require the affirmative vote of a plurality of those shares affected by the
adjournment(s) that are represented at the Special Meeting in person or by
proxy.  If a quorum is present, the persons named as proxies will vote those
proxies that they are entitled to vote FOR the particular proposal for which a
quorum exists in favor of such adjournment(s), and will vote those proxies
required to be voted AGAINST such proposal against any adjournment(s).  A
shareholder vote may be taken with respect to one or more Stellar Funds (but not
the other Stellar Funds) on some or all matters before any such adjournment(s)
if a quorum is present and sufficient votes have been received for approval with
respect to such Funds.

                                      -68-
<PAGE>

          A quorum is constituted with respect to each of the share classes of
each of the Stellar Funds by the presence in person or by proxy of the holders
of more than 50% of the outstanding shares thereof entitled to vote at the
Special Meeting.  For purposes of determining the presence of a quorum for
transacting business at the Special Meeting, abstentions will be treated as
shares that are present at the Special Meeting but which have not been voted.
Abstentions will have the effect of a "no" vote for purposes of obtaining the
requisite approvals of the Reorganization Agreement.  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 abstentions.

     Annual Meetings and Shareholder Meetings.  Neither Stellar nor Firstar
presently intends to hold annual meetings of shareholders for the election of
Trustees and other business unless otherwise required by the 1940 Act.  Under
certain circumstances, however, holders of at least 10% of the outstanding
shares of Stellar or Firstar have the right to call a meeting of shareholders.

     4.   Valuation of Assets.
          -------------------

          (a) With respect to each Stellar Fund, the value of its Assets shall
be the value of such Assets computed as of the time at which its net asset value
is calculated at the Applicable Valuation Time (as hereinafter defined). The net
asset value of the Stellar Fund Assets to be transferred to the Firstar Funds
shall be computed by Stellar and shall be subject to adjustment by the amount,
if any, agreed to by Stellar and the respective Stellar Funds and Firstar and
the respective Firstar Funds. In determining the value of the securities
transferred by a Stellar Fund to its Corresponding Firstar Fund, each security
shall be priced in accordance with the pricing policies and procedures of such
Stellar Fund as described in its then current prospectus(es) and statement of
additional information. For such purposes, price quotations and the security

                                      -19-
<PAGE>

characteristics relating to establishing such quotations shall be determined by
Stellar, provided that such determination shall be subject to the approval of
Firstar.  Firstar and Stellar agree to use all commercially reasonable efforts
to resolve, prior to the Applicable Valuation Time, any material pricing
differences between the prices of portfolio securities determined in accordance
with the pricing policies and procedures of a Firstar Fund and those determined
in accordance with the pricing policies and procedures of its Corresponding
Stellar Fund.

     (b) It is understood and agreed that the net asset value of the Assets of
those Stellar Funds that are money market funds shall be based on the amortized
cost valuation procedures that have been adopted by the Board of Trustees of
Stellar; provided that if the difference between the per share net asset values
of any such Stellar Fund and its Corresponding Firstar Fund equals or exceeds
$0.0010 at the Applicable Valuation Time, as computed by using market values in
accordance with the policies and procedures established by Stellar, either party
shall have the right to postpone the Applicable Valuation Time and Applicable
Effective Time of the Reorganization (as hereinafter defined) with respect to
such Funds until such time as the per share difference is less than $0.0010.

     (c) At least fifteen (15) business days prior to the Applicable Effective
Time of the Reorganization, each Stellar Fund will provide its Corresponding
Firstar Fund with a schedule of its securities and other Assets and Liabilities
of which it is aware, and such Firstar Fund will provide the Stellar Fund with a
copy of the current investment objective and policies applicable to such Firstar
Fund.  Each Stellar Fund reserves the right to sell any of the securities or
other Assets shown on the list of the Fund's Assets prior to the Applicable
Effective Time of

                                      -20-
<PAGE>

the Reorganization but will not, without the prior approval of Firstar, acquire
any additional securities other than securities which the Corresponding Firstar
Fund is permitted to purchase in accordance with its stated investment objective
and policies. At least ten (10) business days prior to the Applicable Effective
Time of the Reorganization, each Firstar Fund will advise its Corresponding
Stellar Fund of any investments of such Stellar Fund shown on such schedule
which the Firstar Fund would not be permitted to hold, pursuant to its stated
investment objective and policies or otherwise. In the event that the Stellar
Fund holds any investments that its Corresponding Firstar Fund would not be
permitted to hold under its stated investment objective or policies, the Stellar
Fund, if requested by the Firstar Fund and to the extent permissible and
consistent with the Stellar Fund's own investment objective and policies, will
dispose of such securities prior to the Applicable Effective Time of the
Reorganization. In addition, if it is determined that the portfolios of the
Stellar Fund and the Firstar Fund, when aggregated, would contain investments
exceeding certain percentage limitations to which the Firstar Fund is or will be
subject with respect to such investments, the Stellar Fund, if requested by the
Firstar Fund and, to the extent permissible and consistent with the Stellar
Fund's own investment objective and policies, will dispose of and/or reinvest a
sufficient amount of such investments as may be necessary to avoid violating
such limitations as of the Applicable Effective Time of the Reorganization.

following the First Valuation Time, unless otherwise agreed in writing by the
parties hereto. Notwithstanding anything herein to the contrary, in the event
that at an Applicable Valuation Time, (a) the New York Stock Exchange shall be
closed to trading or trading thereon 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 Firstar or Stellar, accurate appraisal of the value of the
net assets of a Firstar Fund or a Stellar Fund is impracticable, such Valuation
Time shall be postponed until the first business day after the day when trading
shall have been fully resumed without restriction or disruption, reporting shall
have been restored and accurate appraisal of the value of the net assets of the
Firstar Funds and the Stellar Funds is practicable in the judgment of Firstar
and Stellar.

Second Valuation Time as is agreed to in writing by an authorized officer of
each of the parties). The date and time at which the above-described actions are

respect to the Shell Firstar Funds and the Continuing Stellar Funds. To the

and, to Firstar's knowledge, there are no levies, liens or other encumbrances

<PAGE>

each Firstar Fund of the transactions contemplated by this Agreement except (i)

Fund pursuant to the terms hereof shall have been duly authorized as of the
Applicable Effective Time of the Reorganization and, when so issued and
delivered, shall be registered under the 1933 Act, duly and validly issued, and
fully paid and non-assessable, and no shareholder of any Firstar Fund shall have
any statutory or contractual preemptive right of subscription or purchase in
respect thereof.

          (n) For the period beginning at the Applicable Effective Time of the
Reorganization with respect to the Shell Firstar Funds and the Continuing

such Trustees and officers of Stellar for the period they served as such and is

capacities as such, under Stellar's Declaration of Trust as in effect as of the

    Expense Summaries of the Stellar Funds and Corresponding Firstar Funds


          The following tables (a) compare the fees and expenses as of April 30,
2000, for the Stellar Funds and their Corresponding Firstar Funds and (b) show
the estimated fees and expenses for the Corresponding Firstar Funds on a pro
forma basis after giving effect to the Reorganization. The purpose of these
tables is to assist shareholders in understanding the various costs and expenses
that investors in these portfolios will bear as shareholders. The tables do not
reflect any charges that may be imposed by institutions directly on their
customer accounts in connection with investments in the portfolios. The fund
operating expense levels shown in this Proxy/Prospectus assume current net asset
levels; pro forma expense levels shown should not be considered an actual
representation of future expenses or performance. Such pro forma expense levels
project anticipated levels but may be greater or less than those shown.

          The Firstar Ohio Tax-Free Money Market Fund, Firstar U.S. Government
Securities Fund, Firstar National Municipal Bond Fund, Firstar Strategic Income
Fund, Firstar Large Cap Growth Fund, Firstar Relative Value Fund, Firstar
Science & Technology Fund and Firstar Global Equity Fund are new investment
portfolios with nominal assets and liabilities that will commence operations
upon completion of the Reorganization.

          FIRMCO has committed to waiving/reimbursing fees as needed to ensure
that total operating expense ratios will not exceed the pro forma after waiver
expense ratios until October 31, 2001.

  *   In the Reorganization, holders of Class A Shares of the Stellar Strategic
      Income Fund will receive Retail A Shares of the Firstar Strategic Income
      Fund. In addition, holders of Class B Shares of the Stellar Strategic
      Income Fund who purchased their shares through an investment management,
      trust, custody, or other agency relationship with Firstar Bank, N.A., will
      receive Institutional Shares of the Firstar Strategic Income Fund. All
      other holders of Class B Shares of the Stellar Strategic Income Fund will
      receive Retail B Shares of the Firstar Strategic Income Fund.

  1.  The Firstar Strategic Income Fund has not yet commenced operations. The
      Firstar Strategic Income Fund will continue the operations of the Stellar
      Strategic Income Fund upon consummation of the Reorganization relating to
      that Fund.

  2.  This amount applies if you sell your shares in the first year after
      purchase and gradually declines until it is eliminated after six years.
      After six years, Stellar Class B Shares automatically convert to Class A
      Shares and Firstar Retail B Shares automatically convert to Retail A
      Shares.

  3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
      Shares) and $15.00 for each non systematic withdrawal from a Retirement
      Account for which Firstar Bank, N.A. is custodian.

*    The Mercantile U.S. Government Securities Portfolio is expected to
     reorganize into the Firstar U.S. Government Securities Fund in connection
     with the Reorganization. The Reorganization of the Stellar U.S. Government
     Income Fund into the Firstar U.S. Government Securities Fund and the
     reorganization of the Mercantile U.S. Government Securities Portfolio into
     the Firstar U.S. Government Securities Fund will only occur if the
     shareholders of the appropriate Funds approve each transaction.

1.   The Firstar U.S. Government Securities Fund has not yet commenced
     operations. Upon consummation of the Reorganizations involving the
     Mercantile U.S. Government Securities Portfolio and the Stellar U.S.
     Government Income Fund, the Firstar U.S. Government Securities Fund will
     continue the operations of the Mercantile U.S. Government Securities
     Portfolio.

2.   This amount applies if you sell your shares in the first year after
     purchase and gradually declines until it is eliminated after six years.
     After six years, Stellar Class B Shares automatically convert to Class A
     Shares.

3.   A fee of $15.00 is charged for each non systematic withdrawal from a
     Retirement Account for which Firstar Bank, N.A. is custodian.

4.   Management Fees (after waivers) would be 0.50% for the Combined Fund Pro
     Forma.

5.   The Stellar U.S. Government Income Fund is waiving the 12b-1 fees for Class
     A Shares and Class B Shares for the current fiscal year.

6.   "Other Expenses" for the Funds are expected to be less than the amounts
     shown above because certain service providers are voluntarily waiving a
     portion of their fees and/or reimbursing the Funds for certain "Other
     Expenses."

Other Expenses (after waivers) would be:

7.   As a result of the fee waivers and/or the expense reimbursements, the Total
     Fund Operating Expenses are expected to be less than the amounts shown
     above. These fee waivers and/or reimbursements are made in order to keep
     the annual fees and expenses of the Funds at a certain level.

Total Fund Operating Expenses (after waivers) would be:

+    In the Reorganization, holders of Investor A Shares and Investor B Shares
     of the Mercantile U.S. Government Securities Portfolio will receive Retail
     A Shares and Retail B Shares, respectively, of the Firstar U.S. Government
     Securities Fund. In addition, holders of Class A Shares and Class B Shares
     of Stellar U.S. Government Income Fund who did not purchase their shares
     through an investment management, trust, custody, or other agency
     relationship with Firstar Bank, N.A., will receive Retail A Shares and
     Retail B Shares, respectively, of the Firstar U.S. Government Securities
     Fund.

*    The Mercantile U.S. Government Securities Portfolio is expected to
     reorganize into the Firstar U.S. Government Securities Fund in connection
     with the Reorganization. The Reorganization of the Stellar U.S. Government
     Income Fund into the Firstar U.S. Government Securities Fund and the
     reorganization of the Mercantile U.S. Government Securities Portfolio into
     the Firstar U.S. Government Securities Fund will only occur if the
     shareholders of the appropriate Funds approve each transaction.

/1./ The Firstar U.S. Government Securities Fund has not yet commenced
     operations. Upon consummation of the Reorganizations involving the
     Mercantile U.S. Government Securities Portfolio and the Stellar U.S.
     Government Income Fund, the Firstar U.S. Government Securities Fund will
     continue the operations of the Mercantile U.S. Government Securities
     Portfolio.

2.   This amount applies if you sell your shares in the first year after
     purchase and gradually declines until it is eliminated after six years.
     After six years, Mercantile Investor B Shares automatically convert to
     Investor A Shares, Stellar Class B Shares automatically convert to Class A
     Shares, and the Combined Fund Pro Forma Retail B Shares automatically
     convert to Retail A Shares.

3.   A fee of $12.00 is charged for each wire redemption (Retail A Shares and
     Retail B Shares) and $15.00 for each non-systematic withdrawal from a
     Retirement Account for which Firstar Bank, N.A. is custodian.

4.   Management Fees (after waivers) would be 0.50% for the Combined Fund Pro
     Forma.

5.   The Stellar U.S. Government Income Fund is waiving the 12b-1 fees for Class
     A Shares and Class B Shares for the current fiscal year.

6.   The total of all 12b-1 fees and shareholder servicing fees may not exceed,
     in the aggregate, the annual rate of 0.25% of the Fund's average daily net
     assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
     with respect to the Retail A Shares for the current fiscal year.

7.   "Other Expenses" for the Funds are expected to be less than the amounts
     shown above because certain service providers are voluntarily waiving a
     portion of their fees and/or reimbursing the Funds for certain "Other
     Expenses."

Other Expenses (after waivers) would be:

*  The Mercantile National Municipal Bond Portfolio is expected to reorganize
   into the Firstar National Municipal Bond Fund in connection with the
   Reorganization. The Reorganization of the Stellar Insured Tax-Free Bond Fund
   into the Firstar National Municipal Bond Fund and the reorganization of the
   Mercantile National Municipal Bond Portfolio into the Firstar National
   Municipal Bond Fund will only occur if the shareholders of the appropriate
   Funds approve each transaction.

1.  The Firstar National Municipal Bond Fund has not yet commenced operations.
    Upon consummation of the Reorganizations involving the Mercantile National
    Municipal Bond Portfolio and the Stellar Insured Tax-Free Bond Fund, the
    Firstar National Municipal Bond Fund will continue the operations of the
    Mercantile National Municipal Bond Portfolio.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Stellar Class B Shares automatically convert to Class A Shares.

3.  Management Fees (after waivers) would be 0.55% for the Stellar Insured Tax-
    Free Bond Fund.

4.  The Stellar Insured Tax-Free Bond Fund does not intend to pay 12b-1 fees
    with respect to the Class A Shares and Class B Shares for the current fiscal
    year.

+   In the Reorganization, holders of Investor A Shares and Investor B Shares of

    Shares and Retail B Shares, respectively, of the Firstar National Municipal
    Bond Fund. In addition, holders of Class A Shares and Class B Shares of
    Stellar Insured Tax-Free Bond Fund who did not purchase their shares through
    an investment management, trust, custody, or other agency relationship with
    Firstar Bank, N.A., will receive Retail A Shares and Retail B Shares,
    respectively, of the Firstar National Municipal Bond Fund.

*   The Mercantile National Municipal Bond Portfolio is expected to reorganize
    into the Firstar National Municipal Bond Fund in connection with the
    Reorganization. The Reorganization of the Stellar Insured Tax-Free Bond Fund
    into the Firstar National Municipal Bond Fund and the reorganization of the
    Mercantile National Municipal Bond Portfolio into the Firstar National
    Municipal Bond Fund will only occur if the shareholders of the appropriate
    Funds approve each transaction.

1.  The Firstar National Municipal Bond Fund has not yet commenced operations.
    Upon consummation of the Reorganizations involving the Mercantile National
    Municipal Bond Portfolio and the Stellar Insured Tax-Free Bond Fund, the
    Firstar National Municipal Bond Fund will continue the operations of the
    Mercantile National Municipal Bond Portfolio.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Mercantile Investor B Shares automatically convert to Investor A
    Shares, Stellar Class B Shares automatically convert to Class A Shares and
    Firstar Retail B Shares automatically convert to Retail A Shares.

3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares).

4.  Management Fees (after waivers) would be 0.55% for the Stellar Insured Tax-
    Free Bond Fund.

5.  Distribution and Service (12b-1) Fees (after waivers) would be:

6.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

7.  "Other Expenses" for the Funds are expected to be less than the amounts
    shown above because certain service providers are voluntarily waiving a
    portion of their fees and/or reimbursing the Funds for certain "Other
    Expenses."

Other Expenses (after waivers) would be:

    Fund Operating Expenses are expected to be less than the amounts shown

________________

         *     This example should not be considered a representation of future
               expenses which may be more or less than those shown. The assumed
               5% annual return is hypothetical and should not be considered a
               representation of past or future annual return. Actual return may
               be greater or less than the assumed amount. This example assumes
               that all dividends and other distributions are reinvested.

The purpose of the foregoing tables is to assist an investor in understanding
the various costs and expenses that an investor in the Funds will bear directly
or indirectly.

*   In the Reorganization, holders of Class Y Shares of the Stellar Growth
    Equity Fund will receive Institutional Shares of the Firstar Large Cap
    Growth Fund, holders of Class A Shares of the Stellar Growth Equity Fund
    will receive Retail A Shares of the Firstar Large Cap Growth Fund, and
    holders of Class B Shares of the Stellar Growth Equity Fund will receive
    Retail B Shares of the Firstar Large Cap Growth Fund.

1.  The Firstar Large Cap Growth Fund has not yet commenced operations. The
    Firstar Large Cap Growth Fund will continue the operations of the Stellar
    Growth Equity Fund upon consummation of the Reorganization relating to that
    Fund.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Stellar Class B Shares automatically convert to Class A Shares and
    Firstar Retail B Shares automatically convert to Retail A Shares.

3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares) and $15.00 for each non systematic withdrawal from a Retirement
    Account for which Firstar Bank, N.A. is custodian.

4.  Management Fees (after waivers) would be 0.91% for the Combined Fund Pro
    Forma.

5.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

6.  "Other Expenses" are expected to be less than the amounts shown above
    because certain service providers are voluntarily waiving a portion of their
    fees and/or reimbursing the Funds for certain "Other Expenses."

    "Other Expenses" (after waivers) would be:

7.  As a result of the fee waivers and/or the expense reimbursements, the Total
    Fund Operating Expenses are expected to be less than the amounts shown

    annual fees and expenses of the Funds at a certain level.

*   In the Reorganization, holders of Class Y Shares of the Stellar Relative
    Value Fund will receive Institutional Shares of the Firstar Relative Value
    Fund, holders of Class A Shares of the Stellar Relative Value Fund will
    receive Retail A Shares of the Firstar Relative Value Fund, and holders of
    Class B Shares of the Stellar Relative Value Fund will receive Retail B
    Shares of the Firstar Relative Valve Fund.

1.  The Firstar Relative Value Fund has not yet commenced operations. The
    Firstar Relative Value Fund will continue the operations of the Stellar
    Relative Value Fund upon consummation of the Reorganization relating to that
    Fund.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Stellar Class B Shares automatically convert to Class A Shares and
    Firstar Retail B Shares automatically convert to Retail A Shares.

3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares) and $15.00 for each non systematic withdrawal from a Retirement
    Account for which Firstar Bank, N.A. is custodian.

4.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

5.  "Other Expenses" are expected to be less than the amounts shown above
    because certain service providers are voluntarily waiving a portion of their
    fees and/or reimbursing the Funds for certain "Other Expenses."

    "Other Expenses" (after waivers) would be:

*   In the Reorganization, holders of Class Y Shares of the Stellar Science &
    Technology Fund will receive Institutional Shares of the Firstar Science &
    Technology Fund, holders of Class A Shares of the Stellar Science &
    Technology Fund will receive Retail A Shares of the Firstar Science &
    Technology Fund, and holders of Class B Shares of the Stellar Science &
    Technology Fund will receive Retail B Shares of the Firstar Science &
    Technology Fund.

1.  The Firstar Science & Technology Fund has not yet commenced operations. The
    Firstar Science & Technology Fund will continue the operations of the
    Stellar Science & Technology Fund upon consummation of the Reorganization
    relating to that Fund.

2.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Stellar Class B Shares automatically convert to Class A Shares and
    Firstar Retail B Shares automatically convert to Retail A Shares.

3.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares) and $15.00 for each non-systematic withdrawal from a Retirement
    Account for which Firstar Bank, N.A. is custodian.

4.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

5.  "Other Expenses" are expected to be less than the amounts shown above
    because certain service providers are voluntarily waiving a portion of their
    fees and/or reimbursing the Funds for certain "Other Expenses."

    "Other Expenses" (after waivers) would be:

----------
    *     This example should not be considered a representation of future
          expenses which may be more or less than those shown. The assumed 5%
          annual return is hypothetical and should not be considered a
          representation of past or future annual return. Actual return may be
          greater or less than the assumed amount. This example assumes that all
          dividends and other distributions are reinvested.

The purpose of the foregoing tables is to assist an investor in understanding
the various costs and expenses that an investor in the Funds will bear directly
or indirectly.

*   In the Reorganization, holders of Class Y Shares of the Stellar Fund will
    receive Institutional Shares of the Firstar Balanced Income Fund, holders of
    Class A Shares of the Stellar Fund will receive Retail A Shares of the
    Firstar Balanced Income Fund, and holders of Class B Shares of the Stellar
    Fund will receive Retail B Shares of the Firstar Balanced Income Fund.

1.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Stellar Class B Shares automatically convert to Class A Shares and
    Firstar Retail B Shares automatically convert to Retail A Shares.

2.  A fee of $12.00 is charged for each wire redemption (Retail A and B Shares)
    and $15.00 for each non systematic withdrawal from a Retirement Account for
    which Firstar Bank, N.A. is custodian.

*   In the Reorganization, holders of Class A Shares of the Stellar Capital
    Appreciation Fund will receive Retail A Shares of the Firstar MidCap Index
    Fund. In addition, holders of Class B Shares of the Stellar Capital
    Appreciation Fund who purchased their shares through an investment
    management, trust, custody, or other agency relationship with Firstar Bank,
    N.A., will receive Institutional Shares of the Firstar MidCap Index Fund.
    All other holders of Class B Shares of the Stellar Capital Appreciation Fund
    will receive Retail B Shares of the Firstar MidCap Index Fund.

1.  This amount applies if you sell your shares in the first year after purchase
    and gradually declines until it is eliminated after six years. After six
    years, Stellar Class B Shares automatically convert to Class A Shares and
    Firstar Retail B Shares automatically convert to Retail A Shares.

2.  A fee of $12.00 is charged for each wire redemption (Retail A and Retail B
    Shares) and $15.00 for each non systematic withdrawal from a Retirement
    Account for which Firstar Bank, N.A. is custodian.

    Combined Fund Pro Forma..............................             0.15%
    ---------------------------------------------------------------------------

4.  The Stellar Capital Appreciation Fund does not intend to pay 12b-1 fees with
    respect to the Class A Shares for the current fiscal year.

5.  The total of all 12b-1 fees and shareholder servicing fees may not exceed,
    in the aggregate, the annual rate of 0.25% of the Fund's average daily net
    assets for the Retail A Shares. The Fund does not expect to pay 12b-1 fees
    with respect to the Retail A Shares for the current fiscal year.

6.  "Other Expenses" are expected to be less than the amounts shown above
    because certain service providers are voluntarily waiving a portion of their
    fees and/or reimbursing the Funds for certain "Other Expenses."

    "Other Expenses" (after waivers) would be:

                                 APPENDIX III

                Investment Objectives, Limitations and Certain
              Significant Investment Policies of the Reorganizing
                 Stellar Funds and Corresponding Firstar Funds

     This Appendix highlights the investment objectives and certain significant
similarities and differences among the investment limitations and policies of
certain of the Reorganizing Stellar Funds and their Corresponding Firstar Funds.
Because the Stellar Ohio Tax-Free Money Market Fund, Stellar Strategic Income
Fund, Stellar Growth Equity Fund, Stellar Relative Value Fund, Stellar Science &
Technology Fund, and Stellar International Equity Fund will be reorganized into
Shell Firstar Funds that have substantially the same investment objectives,
policies and restrictions as their corresponding Continuing Stellar Funds, they
are not discussed in this Appendix.  The following is qualified in its entirety
by the more detailed information included in the prospectuses and statements of
additional information for the Stellar Funds and the Corresponding Firstar Funds
which are incorporated by reference into this Proxy/Prospectus.

1.   Stellar Treasury Fund and Firstar U.S. Treasury Money Market Fund

     Investment Objectives:

     (a)  Stellar Treasury Fund:  Seeks to achieve stability of principal and
          ---------------------
          current income consistent with stability of principal.  This
          investment objective is fundamental and may not be changed without the
          approval of the Fund's shareholders.

     (b)  Firstar U.S. Treasury Money Market Fund:  Seeks to provide a high
          ---------------------------------------
          level of taxable current income exempt from state income taxes
          consistent with liquidity, the preservation of capital and a stable
          net asset value.  This investment objective is not fundamental and may
          be changed by the Firstar Board of Directors without shareholder
          approval.

     Comment:  Both the Stellar Treasury Fund and the Mercantile Treasury Money
Market Portfolio will reorganize into the Firstar U.S. Treasury Money Market
Fund.  It is expected that at the time of the Reorganization the Firstar U.S.
Treasury Money Market Fund will adopt an investment objective and certain non-
fundamental policies and restrictions that are substantially the same as those
of the Stellar Treasury Fund.  The Firstar U.S. Treasury Money Market Fund,
however, will retain its own fundamental investment limitations.  Accordingly,
set forth below is a description of the significant differences between the
fundamental investment limitations of the Stellar Treasury Fund and the Firstar
U.S. Treasury Money Market Fund.

     The Stellar Treasury Fund has a fundamental policy that it may borrow up to
33-1/3% of the value of its net assets, while the Firstar U.S. Treasury Money
Market Fund has a fundamental policy that it may only borrow up to 10% of the
value of its net assets.  In addition, the Firstar U.S. Treasury Money Market
Fund has a fundamental policy that it may lend up to 30% of its total net
assets, while the Stellar Treasury Fund has a fundamental policy that it may not
engage in securities lending.

                                     III-1
<PAGE>

2. Stellar Tax-Free Money Market Fund and Firstar Tax-Exempt Money Market Fund.

     Investment Objectives:

     Stellar Tax-Free Money Market Fund:  Seeks to provide current income exempt
     ----------------------------------
from federal regular income tax consistent with stability of principal.  This
investment objective is fundamental and may not be changed without the approval
of the Fund's shareholders.

     Firstar Tax-Exempt Money Market Fund:  Seeks to provide a high level of
     ------------------------------------
current income exempt from federal income taxes consistent with liquidity, the
preservation of capital and a stable net asset value.  This investment objective
is not fundamental and may be changed by the Firstar Board of Directors without
shareholder approval.

     Comment:  Both the Stellar Tax-Free Money Market Fund and Mercantile Tax-
Exempt Money Market Portfolio will reorganize into the Firstar Tax-Exempt Money
Market Fund.  Each Fund is a money market fund and in accordance with Rule 2a-7
under the 1940 Act, will generally invest in instruments with remaining
maturities not exceeding 397 days, and each Fund's dollar weighted average
portfolio maturity may not exceed 90 days.  Both the Stellar Tax-Free Money
Market Fund and the Firstar Tax-Exempt Money Market Fund will purchase only
securities that are rated in the highest short-term rating category (i.e., rated
AAA by S&P or Aaa by Moody's) by at least two nationally recognized rating
agencies (or one such rating if only one agency has rated the instrument) or
that are determined to be of comparable quality.  However, the Stellar Tax-Free
Money Market Fund may purchase bonds which have no short-term ratings but which
have long-term ratings by nationally recognized statistical rating organizations
("NRSROs") in the two highest ratings categories.  This Fund has the ability but
no present intention of investing in municipal securities that are rated MIG-2
or VMIG-2 by Moody's Investors Service, Inc. ("Moody's"), F2 by Fitch IBCA, Inc.
("Fitch"), or A-2 or SP-2 by Standard and Poor's Rating Services ("S&P") and in
tax-exempt commercial paper that is rated P-2 by Moody's, A-2 by S&P, or F2 by
Fitch.

     The Stellar Tax-Free Money Market Fund invests its assets so that at least
80% of its annual interest income is exempt from federal regular income tax and
not subject to the alternative minimum tax.  The Fund's portfolio primarily
consists of debt obligations issued by or on behalf of states, territories and
possessions of the United States, and any political subdivision or financing
authority of any of these, the income from which is exempt from federal regular
income tax.

     Similarly, the Firstar Tax-Exempt Money Market Fund invests at least 80% of
its net assets in a diversified portfolio of dollar-denominated debt obligations
("municipal obligations") issued by or on behalf of states, territories and
possessions of the United States, the District of Columbia and their
authorities, instrumentalities, agencies and political subdivisions, that are
exempt from federal income taxes and with remaining maturities of 13 months or
less.

     While the Stellar Tax-Free Money Market Fund and the Firstar Tax-Exempt
Money Market Fund invest in a similar pool of investments, there are certain
differences.  Particularly,

                                     III-2
<PAGE>

the Funds have similar, but slightly different, policies with respect to
concentration of their assets. The Stellar Tax-Free Money Market Fund may invest
more than 25% of its total assets in securities credit-enhanced by banks while
the Firstar Tax-Exempt Money Market Fund may invest more than 25% of its assets
in municipal obligations covered by insurance policies. Additionally, while the
Stellar Tax-Free Money Market Fund does not intend to purchase securities that
would increase the percentage of its assets invested in the securities of
governmental subdivisions located in any one state, territory or U.S. possession
to more than 25%, the Fund may invest more than 25% of the value of its assets
in tax-exempt project notes guaranteed by the U.S. government, regardless of the
issuing municipality. While the Firstar Tax-Exempt Money Market Fund does not
presently intend to do so on a regular basis, it may invest more than 25% of its
total assets in municipal obligations, the issuers of which are located in the
same state or the interest on which is paid solely from the revenue of similar
projects.

     The Stellar Tax-Free Money Market Fund, but not the Firstar Tax-Exempt
Money Market Fund, may invest in municipal leases and repurchase agreements.
Further, the Stellar Tax-Free Money Market Fund may borrow money directly up to
one-third of the value of its total assets as a temporary or emergency measure
to meet redemption requests and not for investment leverage. The Firstar Tax-
Exempt Money Market Fund may borrow to meet shareholder redemptions up to 10% of
its total assets from banks or through reverse repurchase agreements. The
Stellar Tax-Free Money Market Fund, but not the Firstar Tax-Exempt Money Market
Fund, may purchase securities on a delayed delivery basis. The Firstar Tax-
Exempt Money Market Fund, but not the Stellar Tax-Free Money Market Fund, may
purchase securities on a forward commitment basis. The Stellar Tax-Free Money
Market Fund and the Firstar Tax-Exempt Money Market Fund may purchase securities
on a when-issued basis up to 20% and 25%, respectively, of the value of their
respective assets.

     Although the Stellar Tax-Free Money Market Fund is permitted to make
taxable, temporary investments, the adviser currently has no intention to
generate income subject to federal regular income tax.  The Firstar Tax-Exempt
Money Market Fund may invest in short-term taxable money market obligations
(taxable obligations will not normally exceed 20% of the Fund's total assets)
for temporary defensive purposes.

3. Stellar U.S. Government Income Fund and Firstar U.S. Government Securities
   Fund.

     Investment Objectives:

     Stellar U.S. Government Income Fund:  Seeks to provide current income.  The
     ------------------------------------
Fund's second objective is to achieve capital appreciation.  This investment
objective is fundamental and may not be changed without the approval of the
Fund's shareholders.

     Firstar U.S. Government Securities Fund:  Seeks a high rate of current
     ----------------------------------------
income that is consistent with relative stability of principal.  This investment
objective is not fundamental and may be changed by Firstar's Board of Directors
without shareholder approval.

     Comment:  Both the Stellar U.S. Government Income Fund and the Mercantile
U.S. Government Securities Portfolio will be reorganized into the Firstar U.S.
Government Securities

                                     III-3
<PAGE>

Fund. The Firstar U.S. Government Securities Fund is a newly established Fund
created for the purposes of the Reorganization that has investment objectives,
policies and restrictions that are substantially similar to the Mercantile U.S.
Government Securities Portfolio. The Stellar U.S. Government Income Fund invests
at least 65% of its total assets in securities issued or guaranteed as to
payment of principal and interest by the U.S. government, its agencies or
instrumentalities which produce income. The Fund tries to achieve capital
appreciation and improve total return by increasing or decreasing its average
maturity depending on forecasted interest rates. Up to 35% of the Fund's assets
may be invested in time and savings deposits, mortgage-backed securities,
investment grade corporate debt obligations, asset-backed securities, commercial
paper and debt securities of foreign issuers.

     The Firstar U.S. Government Securities Fund will invest at least 65% of its
total assets in debt obligations issued or guaranteed by the U.S. Government and
its agencies, including U.S. Treasury bonds, notes and bills, as well as
repurchase agreements backed by such obligations.  The Fund may also invest in
mortgage-backed securities issued by U.S. government sponsored entities,
collateralized mortgage obligations and certificates issued by government-backed
trusts.  The Fund's securities maturity will vary from one to 30 years, but the
average weighted maturity generally will not exceed 10 years.

     While the Stellar U.S. Government Income Fund and the Firstar U.S.
Government Securities Fund invest in a similar pool of investments, there are
several differences between the Funds.  Although both Funds may invest in
"stripped" government securities, the Firstar U.S. Government Securities Fund
may not invest in certain types of these securities known as Treasury Income
Growth Receipts ("TIGRs") or Certificates of Accrual on Treasury Securities
("CATS") which are not as liquid as other types of "stripped" U.S. government
securities and are not considered U.S. government securities for purposes of the
1940 Act.  The Stellar U.S. Government Income Fund can invest up to 5% of its
total assets in investment grade debt securities of foreign issuers, while the
Firstar U.S. Government Securities Fund may not invest in foreign securities.

     The Funds also have different restrictions for investments in options.  For
example, the Stellar U.S. Government Income Fund can write covered call and put
options, but the Firstar U.S. Government Securities Fund may only write covered
call options.  The Stellar U.S. Government Income Fund may purchase options in
an amount up to 5% of its total assets, while the Firstar U.S. Government
Securities Fund may purchase options in an amount up to 10% of its net assets.
Further, the aggregate value of securities subject to covered call options may
not exceed 25% of the value of the Firstar U.S. Government Securities Fund's net
assets, while no such restriction is imposed on the Stellar U.S. Government
Income Fund.

4. Stellar Insured Tax-Free Bond Fund and Firstar National Municipal Bond Fund.

     Investment Objectives:

     Stellar Insured Tax-Free Bond Fund:  Seeks to provide current income exempt
     ----------------------------------
from federal income tax by primarily purchasing insured municipal bonds.  This
investment objective is fundamental and may not be changed without the approval
of the Fund's shareholders.

     Firstar National Municipal Bond Fund:  Seeks as high a level of current
     ------------------------------------
income exempt from regular federal income tax as is consistent with conservation
of capital.  This investment objective is not fundamental and may be changed by
the Firstar Board of Directors without shareholder approval.

     Comment:  Both the Stellar Insured Tax-Free Bond Fund and the Mercantile
National Municipal Bond Portfolio will reorganize into the Firstar National
Municipal Bond Fund.  The Firstar National Municipal Bond Fund is a newly
established fund created for the purposes of the Reorganization that has
investment objectives, policies and restrictions that are substantially similar
to those of the Mercantile National Municipal Bond Portfolio.  The Stellar
Insured Tax-Free Bond Fund invests its assets so that at least 80% of its annual
interest income is exempt from federal income tax and not subject to the
alternative minimum tax.  Usually, at least 65% of the value of the fund's
assets is invested in intermediate- to long-term investment grade municipal
securities that are insured as to timely payment.  These insured municipal
securities, that meet the adviser's investment requirements, are either:  (1)
covered by an insurance policy applicable to a particular security, or (2)
insured under master insurance policies issued by municipal bond insurers, which
may be purchased by the fund.  When investing in municipal securities, the
Stellar Insured Tax-Free Bond Fund's investment adviser looks for the following
qualities in an investment:  (i) rated investment grade (i.e., within the top
four rating categories by an NRSRO); (ii) insured by a municipal bond insurance
company which is rated in the top rating category by an NRSRO; (iii) guaranteed
at the time of purchase by the U.S. government as to the payment of principal
and interest; (iv) fully collateralized by an escrow of U.S. government
securities; or (v) determined to be of comparable quality to an investment grade
or better by the investment adviser if the security is unrated.

     The Firstar National Municipal Bond Fund will invest at least 80% of its
total assets in municipal securities that pay interest that is exempt from
federal income tax, including general obligation securities, revenue securities
and private activity bonds.  Under normal conditions, the Fund's investments in
private activity bonds, together with any investments in securities subject to
the alternative minimum tax and taxable obligations, will not exceed 20% of its
total assets.  The Fund's average weighted maturity will generally be 10 years
or less.  No specific percentage of the Fund's assets is invested in municipal
securities that are insured as to timely payment.  The Fund may only invest in
investment grade municipal securities.  The Fund may invest 25% or more of its
net assets in (i) municipal securities whose issuers are in the same state; (ii)
municipal securities the interest on which is paid solely from revenue of
similar projects and (iii) private activity bonds, though it does not presently
intend to do so.  On a temporary defensive basis, the Fund may hold without any
limitation uninvested cash reserves and invest in taxable obligations.

                                     III-5
<PAGE>

     The Stellar Insured Tax-Free Bond Fund may invest in repurchase agreements,
but the Firstar National Municipal Bond Fund may not.  The Stellar Insured Tax-
Free Bond Fund may invest up to 5% of its total net assets in options and
futures contracts, while the Firstar National Municipal Bond Fund may not invest
in options or futures contracts.  The Firstar National Municipal Bond Fund may
invest in tax-exempt derivatives including term option bonds, participations,
beneficial interests in trusts and partnership interests, but expects to invest
less than 5% of its total assets in such securities.  Finally, while the Stellar
Insured Tax-Free Bond Fund may invest up to 20% of its net assets in when-issued
securities, forward commitments and delayed settlement transactions, the Firstar
National Municipal Bond Fund expects that its commitments to purchase when-
issued securities will not exceed 5% of its total net assets and expects that
forward commitments and delayed settlement transactions will not exceed 25% of
its net assets.

5. Stellar Fund and Firstar Balanced Income Fund.

     Investment Objectives:

     Stellar Fund:  Seeks to maximize total return derived from a combination of
     ------------
dividend income and capital appreciation.  This investment objective is
fundamental and may not be changed without the approval of the Fund's
shareholders.

     Firstar Balanced Income Fund:  Seeks to provide current income and the
     ----------------------------
preservation of capital by investing in a balanced portfolio of dividend-paying
equity and fixed-income securities.  This investment objective is not
fundamental and may be changed by the Firstar Board of Directors without
shareholder approval.

     Comment:  The Stellar Fund invests no more than 50% of its net assets in
each of the following categories:  domestic equity securities, domestic fixed-
income securities (including mortgage and asset-backed securities),
international securities (equity and fixed income), real estate securities
(REITs) and short-term securities.  For the Fund's domestic equity securities,
the adviser chooses stocks that it believes to be undervalued compared to stocks
contained in the S & P 500 Composite Stock Price Index.  The companies in which
the Fund invests may be small, medium or large in size.  The Fund's fixed-income
investments include short to long-term, investment grade domestic corporate debt
obligations, obligations of the U.S. government, and notes, bonds, and discount
notes of U.S. government agencies or instrumentalities.  The Stellar Fund will
only invest in bonds rated Baa or higher by Moody's Investors Service, Inc. or
rated BBB or higher by S&P or Fitch IBCA, Inc.

     The Firstar Balanced Income Fund typically invests 50% of its assets in
equity securities and 50% in fixed-income securities, although the actual
percentage of assets invested in each will vary from time to time.  It may
invest no less than 20% and no more than 60% of its assets in equity securities,
and it may invest no less than 40% of its assets in fixed-income securities.
The Fund may also acquire bonds, notes, debentures and preferred stocks if they
provide a current interest stream, and may invest up to 5% of its net assets in
other types of domestic securities having common stock characteristics, such as
rights and warrants to purchase equity

                                     III-6
<PAGE>

securities. The Portfolio's equity securities consist mainly of common stock of
domestic and foreign companies that the Adviser considers to be well managed and
to have attractive fundamental financial characteristics, with market
capitalizations of over $750 million. Except for convertible securities, the
Fund will purchase only fixed-income securities rated investment grade by at
least one rating agency or unrated obligations deemed by the Adviser to be
comparable in quality.

     The Firstar Balanced Income Fund may lend its portfolio securities to
unaffiliated domestic broker/dealers and other institutional investors.  The
Stellar Fund may not lend its securities.

     Both Funds may invest in short-term obligations on a when-issued or delayed
delivery basis.  The Firstar Balanced Income Fund does not expect such
investments to exceed 25% of the value of its total assets, while the Stellar
Fund does not intend to engage in such transactions to an extent that would
cause more than 20% of its assets to be so committed.  The Firstar Balanced
Income Fund may purchase or sell futures contracts, or options thereon, while
the Stellar Fund is not permitted to engage in futures transactions.

     Finally, while the Firstar Balanced Income Fund may borrow from banks and
enter into reverse repurchase agreements in amounts up to 10% of its total
assets, the Stellar Fund may invest up to 33 1/3% of its total assets in reverse
repurchase agreements, but may not borrow from banks.

6. Stellar Capital Appreciation Fund and Firstar MidCap Index Fund.

     Investment Objectives:

     Stellar Capital Appreciation Fund:  Seeks to maximize capital appreciation.
     ---------------------------------
This investment objective is fundamental and may not be changed without approval
of the Fund's shareholders.

     Firstar MidCap Index Fund:  Seeks returns, before Fund expenses, comparable
     -------------------------
to the price and yield performance of publicly traded common stocks in the
aggregate, as represented by the S&P MidCap 400 Index.  This investment
objective is not fundamental and may be changed by the Firstar Board of
Directors without shareholder approval.

     Comment:  The Stellar Capital Appreciation Fund invests at least 50% of the
value of its total assets in equity securities of U.S. companies that have
market capitalizations ranging from  $200 million to $10 billion and whose
shares are traded on the New York or American Stock Exchanges or traded on
NASDAQ or over-the-counter.  In selecting securities, the fund's investment
adviser employs automated quantitative measurement techniques, and considers,
among other things, a security's historical performance, price/earnings ratio,
market capitalization and credit ranking based on the standards of NRSROs.  To a
lesser extent, the Fund may also invest a portion of its net assets in domestic
debt securities, U.S. government securities, international securities, options
and futures and money market instruments.

                                     III-7
<PAGE>

     The Firstar MidCap Index Fund attempts to replicate the performance of the
S&P MidCap 400 Index ("400 Index") before Fund expenses.  Under normal market
conditions, the Fund will invest substantially all of its total assets in
securities included in the 400 index.  At least 80% of the Fund's net assets
will be invested in the common stocks of such companies at all times.  The 400
Index consists of medium-size domestic companies with market capitalizations
between $148 million and $13 billion.  While index funds are traditionally less
managed than equity or bond portfolios, the Firstar MidCap Index Fund's
investment adviser uses capitalization weighting and sector managing techniques
in an effort to keep the Fund's quarterly performance within  0.03% of the 400
Index under normal market conditions.  In addition to the aforementioned
policies, the Fund may also invest a portion of its net assets in futures
contracts and options on futures contracts for hedging purposes, to have fuller
exposure to price movements in stock or bond indices to increase total return or
to maintain liquidity to meet potential shareholder redemptions, invest cash
balances or dividends or minimize trading costs.  In addition, the Fund may also
purchase and sell futures and related options to maintain cash reserves while
simulating full investment in the stocks underlying the 400 Index and to reduce
transaction costs.

     There are several noteworthy differences in the investment policies of the
two Funds.  The Firstar MidCap Index Fund may invest up to 10% of its total
assets in borrowings and reverse repurchase agreements.  The Stellar Capital
Appreciation may invest up to 33 1/3% of its total assets in reverse repurchase
agreements.  Unlike the Firstar MidCap Index Fund, the Stellar Capital
Appreciation Fund may invest up to 10% of its total assets in the securities of
foreign issuers.  While both Funds may participate in securities lending, the
Firstar MidCap Index Fund limits its portfolio lending to 30% of its assets,
while the Stellar Capital Appreciation Fund may lend up to 33 1/3% of its total
assets.  Also, only the Stellar Capital Appreciation Fund may hold convertible
securities and invest a percentage of its assets in warrants.  Unlike the
Firstar MidCap Index Fund, the Stellar Capital Appreciation Fund may invest up
to 20% of its net assets in short-term obligations on a when-issued or delayed
delivery basis.

     While both the Stellar Capital Appreciation Fund and Firstar MidCap Index
Fund may invest up to 5% of their net assets in put and call options, the
Firstar MidCap Index Fund's investments must be based solely on the investment
strategies of the S&P MidCap 400 Index.  The Stellar Capital Appreciation Fund
is not limited in this manner.  In a similar fashion, both Funds may purchase
and sell futures contracts to act as hedge against changes in the value of
portfolio securities due to changes in interest rates and market conditions, but
the Firstar MidCap Index Fund may also purchase and sell futures contracts to
have more exposure to maintain cash reserves while simulating full investment in
the stocks underlying the S&P MidCap 400 Index, to keep its assets substantially
exposed to the market (as represented by the S&P MidCap 400 Index), and to
reduce transaction costs.  As with its investment in put and call options, the
Firstar MidCap Index Fund must base its purchase of futures contracts and
related options on the S&P MidCap 400 Index.

     1.   Sales Charge Reduction - Stellar Class A and Firstar Retail A Shares
          --------------------------------------------------------------------

     The sales charge on purchases of Stellar Class A and Firstar Retail A
     Shares may be reduced through:

          (a)  Rights of Accumulation
               ----------------------

          Stellar Class A Shares and Firstar Retail A Shares.  In calculating
          --------------------------------------------------
     the appropriate sales charge rate, the right allows investors to add the
     value of the Class A/Retail A Shares of the non-money market fund they
     already own, as well as the value of any existing Class A/Retail A Shares
     of any other Fund in the Firstar family of funds, to the amount they are
     currently purchasing.

          (b)  Letter of Intent
               ----------------

               (i)  Stellar Class A Shares
                    ----------------------

                    If an investor intends to purchase at least $50,000 of Class
     A Shares over 13 months, the investor may sign a letter of intent to reduce
     the sales charge. A letter of intent includes a provision allowing Stellar
     to adjust the sales charge depending on the amount the investor actually
     purchases within the 13-month period. It also allows the custodian to hold
     the maximum sales charge in shares in escrow until the purchases are
     completed.

               (ii) Firstar Retail A Shares
                    -----------------------

                    An investor can purchase Retail A Shares of any Firstar non-
     money market fund or Retail A Shares of any fund in the Firstar family of
     funds that charges a sales load over a 13-month period and pay the same
     sales charge the investor would have paid if all shares were purchased at
     once. The investor may obtain the reduced sales charge by means of a
     written letter of intent which expresses a non-binding commitment to invest
     in the aggregate $100,000 or more in Firstar non-money market Fund Retail A
     Shares or Retail A Shares of any Firstar family of funds. The transfer
     agent will hold in escrow shares equal to 5% of the amount indicated in the
     letter of intent for payment of a higher sales charge if an Investor does
     not purchase the full amount indicated in the letter of intent.

               (i)  Stellar Class A Shares
                    ----------------------

                    As the dollar amount of an investor's purchase increases,
     sales charge may decrease (see the table above).

               (ii) Firstar Retail A Shares
                    -----------------------

                    As the dollar amount of an investor's purchase increases,
     their sales charge may decrease (see the table above). For purposes of
     applying the Rights of Accumulation and Letter of Intent privileges, the
     sales charge schedule applies to the combined purchases made by any
     individual and/or spouse purchasing securities for his, her or their own
     account, or the aggregate investments of a trustee or other fiduciary or
     IRA for the benefits of the persons listed below (See "Waivers - Stellar
     Class A Shares and Firstar Retail A Shares").

               (i)  Stellar Class A Shares
                    ----------------------

                    If Class A Shares of any of the Stellar Funds have been
     redeemed, the investor has a one-time right, within 30 days, to reinvest
     the redemption proceeds at the next-determine net asset value without any
     sales charge so long as investor notifies the transfer agent or shareholder
     organization at the time of the request. Investors should inform Stellar,
     in writing, that they are reinvesting so that they will not be overcharged.

               (ii) Firstar Retail A Shares
                    -----------------------

                    If you sell shares of a Firstar Fund or of any Firstar
     family of funds, you may reinvest some or all of the process in the Retail
     A Shares of any Firstar Fund within 60 days without a sales charge, as long
     as the investor notifies the transfer agent or shareholder organization at
     the time of the investor's reinvestment.

     More Information about Exchanging Shares
     ----------------------------------------

     Firstar Funds
     -------------

     Generally, any share class of a Firstar Fund is exchangeable for the same
share class of another Firstar Fund, provided you are eligible to purchase that
share class or Fund. Listed below are permitted exchanges between different
share classes of the Fund.

     .    Retail B Shares of a non-money market fund may be exchanged for Retail
          Shares of a money market fund (except Retail B Shares are not
          exchangeable for any shares of the Institutional Money Market Fund).

     .    Class Y Shares of a non-money market fund are exchangeable for
          Institutional Shares of a money market fund.

     Unless you qualify for a sales charge exemption, an initial sales charge
will be imposed on the exchange if the shares of the Fund being acquired have an
initial sales charge and the shares being redeemed were purchased without a
sales charge. Retail B Shares acquired in an exchange and Money Market Fund
Shares acquired in an exchange for Retail B Shares will be subject to a
contingent deferred sales charge upon redemption in accordance with this
Prospectus. For purposes of computing the contingent deferred sales charge, the
length of time of ownership will be measured from the date of the original
purchase of Retail B Shares.

Shares. Exchanges from Class B to Class C and then to Class A are not permitted.

     E.   Pricing of Shares for each of the Stellar Funds and Firstar Funds

end sales charge.

                    Performance Comparisons of the Existing
                     Firstar Funds and their Corresponding
                                 Stellar Funds

                           Total Return Performance
                                (As of 7/31/00)


     The total returns of the Firstar Funds are competitive with those of the
Stellar Funds as shown below. No Class Y Shares of Firstar's equity funds or
Institutional Shares of Firstar's money market funds were outstanding as of
7/31/00. No Class B Shares of Stellar's Insured Tax-Free Bond Fund were
outstanding as of 7/31/00. Performance comparisons between the (1) Stellar
Insured Tax-Free Bond Fund and the Mercantile National Municipal Bond Portfolio
and (2) Stellar U.S. Government Income Fund and Mercantile U.S. Government
Securities Portfolio have been included. The Stellar Insured Tax-Free Bond Fund
and the Mercantile National Municipal Bond Portfolio will be reorganized into
the Firstar National Municipal Bond Fund, and the Stellar U.S. Government Income
Fund and the Mercantile U.S. Government Securities Portfolio will be reorganized
into the Firstar U.S. Government Securities Fund. However, each of the Firstar
Funds will be adopting the investment objectives and policies of its
corresponding Mercantile Fund. The Firstar National Municipal Bond Fund and
Firstar U.S. Government Securities Fund are newly organized Funds that have been
specifically created for this Reorganization and do not have any performance
history. In addition, it is anticipated that upon the reorganization of the
Stellar Treasury Fund and Mercantile Treasury Money Market Fund into the Firstar
U.S. Treasury Money Market Fund, the Firstar U.S. Treasury Money Market Fund
will adopt the investment objectives and policies of the Stellar Treasury Fund.
There is no performance information for the Firstar MidCap Index Fund because
the Fund commenced operations on November 4, 1999. Performance shown is based on
historical earnings and is not predictive of future performance. Performance
reflects reinvestment of dividends and other earnings. Performance reflects fee
waivers in effect. If fee waivers were not in place, a Fund's performance would
be reduced.

* The Firstar Balanced Income Fund commenced operations on December 1, 1997. The
performance of the Firstar Balanced Income Fund for the period prior to December
1, 1997 is the performance of a common trust fund managed by FIRMCO which
operated during the periods prior to commencement of operations of the Firstar
Balanced Income Fund using materially equivalent investment objectives,
policies, guidelines and restrictions as the Firstar Balanced Income Fund. The
common trust fund transferred its assets to the Balanced Income Fund at the
commencement of operations. At the time of the transfer, FIRMCO did not manage
any other collective investment or common trust funds using materially
equivalent investment objectives, policies, guidelines and restrictions to those
of the Firstar Balanced Income Fund. The common trust fund was not registered
under the 1940 Act, and was not subject to certain restrictions that are imposed
by the 1940 Act and the Code. If the common trust fund had been registered under
the 1940 Act, performance may have been adversely affected. The performance of
the common trust fund has been restated to reflect the Firstar Balanced Income
Fund's expenses for its first year of operations. Prior to January 10, 1995, the
Firstar Balanced Income Fund offered to investors one series of shares with
neither a sales charge nor a service fee. For the Retail A Shares, the average
annual total return calculation reflects a maximum initial sales charge of 5.50%
but for periods prior to January 10, 1995, performance does not reflect service
organization fees. If service organization fees had been reflected, performance
would be reduced.

** Class B Shares of the Stellar Fund commenced operations on March 31, 2000, so
performance information has not been provided for this class of shares.

APPENDIX VI - MANAGEMENT DISCUSSION OF FIRSTAR FUND PERFORMANCE

--------------------------------------------------------------------------------
                              BALANCED INCOME FUND
--------------------------------------------------------------------------------

Firstar Balanced Income Fund seeks to provide current income and preserve
capital by investing in stocks and bonds. Typically, the Fund will invest 50% of
assets in common stocks of large, dividend-paying equity securities, with the
balance invested in intermediate-term high quality bonds and money markets. As
of October 31, 1999, the Fund consisted of 47% in common and preferred stocks,
43% in bonds, and 10% in money markets. The weighted average market
capitalization of the common stocks was $50 billion, considerably less than the
$116 billion average market capitalization of the Standard & Poor's 500 Stock
Index. Bond holdings within the portfolio had a weighted average duration of 3.5
years, matching the duration of the Lehman Brothers Intermediate
Government/Corporate Bond Index. For the 12 months ended October 31, 1999,
Firstar Balanced Income Fund returned +6.3% (Institutional shares), compared
with the return of 12.6% for the Lipper Balanced Fund Index.

For the fiscal year ended October 31, 1999, the Standard & Poor's 500 advanced
25.7%, propelled by a 69.4% gain for the technology sector. In fact, technology
stocks contributed over 40% of the return, with Microsoft, Cisco, Lucent, Intel
and America Online responsible for one-quarter of the S&P 500's 12-month return.
The Standard & Poor's 500 return without technology was +15.1%. Strength was
also seen in communication services stocks, with the sector's +31% return driven
by MCI Worldcom and Nextel. The consumer cyclicals sector also beat the Index
return, posting a +28% gain led by Wal-Mart and Home Depot. What is notable
regarding these top-performing companies is their high relative price-to-
earnings (P/E) ratios, averaging 64 times 1999 earnings, and their low dividend
yield, averaging .1%. This was a challenging environment given the Balanced
Income Fund's focus on income-producing securities at attractive multiples.

The equity portion of the Balanced Income Portfolio focuses on companies that
pay a dividend. Our strategy in managing the equity portion of the portfolio is
to own companies that demonstrate predictable sales and earnings growth, strong
balance sheets, and innovative management. (Standard & Poor's awards a stock
rating of "A" to "A+" to companies with these characteristics, while companies
with inconsistent or negligible earnings histories and questionable balance
sheets receive ratings of "C" or "D.") We believe over a long period of time
this strategy results in competitive, risk-adjusted returns for our
shareholders. This was not, however, a winning strategy for the fiscal year
ended October 31, which witnessed higher quality (A-rated) companies up 5.8%
versus lower quality companies (C&D-rated) up 48.4%.

The goal of the fixed-income component of Firstar Balanced Income Fund is to
provide an annual rate of total return comparable to the return of the Lehman
Brothers Intermediate Government/Corporate Bond Index. After the dramatic
widening of yield spreads in non-Treasury sectors last year, we selectively
added to our holdings in the corporate, asset-backed and mortgage-backed
sectors. The subsequent tightening of yield spreads in these sectors in 1999 has
contributed to the performance of the Fund over the last 12 months. Our careful,
research-intense process of selecting investment-grade issues in these sectors
gives the Fund a high-quality focus. Over 70% of the fixed-income portion of the
Fund is invested in obligations rated Aaa/AAA or higher. Among corporate bonds,
we have a preference for finance, banking and brokerage issues along with
dollar-denominated international ("Yankee") securities. We think these
sectors represent exceptional value moving forward. The hallmark of our fixed-
income approach is our consistent, risk-controlled style in all market climates.

The Balanced Income Fund is designed to reduce risk by investing in conservative
stocks and conservative bonds. The Fund's stocks have not been rewarded in the
current environment, but we believe that predictable earnings growth from
undervalued companies will be rewarded in this fast-changing market.

Thank you for your support of Firstar Balanced Income Fund.

This chart assumes an initial investment of $10,000 made on 12/1/97 (inception).
Performance reflects fee waivers in effect. In the absence of fee waivers, total
return would be reduced. Performance is shown for Institutional shares, which
have lower expenses than Series A or Series B shares. If those fees and expenses
were reflected in the chart above, total return would have been reduced. Returns
shown include the reinvestment of all dividends and other distributions. Past
perform ance is not predictive of future performance. Investment return and
principal value will fluc tuate, so that your shares, when redeemed, may be
worth more or less than their original cost.

                              GENERAL INFORMATION

     The Reorganization contemplates the transfer of substantially all of the
assets and liabilities of each Mercantile Fund to a Corresponding Firstar Fund
in exchange for shares of designated classes of the Corresponding Firstar Fund.

     The Shares issued by a Firstar Fund will have an aggregate value equal
to the aggregate value of the shares of the respective corresponding Mercantile
Funds that were outstanding immediately before the effective time of the
Reorganization.

     After the transfer of substantially all of their assets and liabilities in
exchange for the Firstar Fund shares, the Mercantile Funds will distribute the
shares to their shareholders in liquidation of such Mercantile Fund. Each
shareholder owning shares of a particular Mercantile Fund at the effective time
of the Reorganization will receive shares from its Corresponding Firstar Fund of
equal value, and will receive any unpaid dividends or distributions that were
declared before the effective time of the Reorganization on shares of the
Mercantile Funds. The Corresponding Firstar Fund will establish an account for
each former shareholder of the Mercantile Funds reflecting the appropriate
number of shares distributed to the shareholder. These accounts will be
substantially identical to the accounts maintained by Mercantile Funds for each
shareholder. Upon completion of the Reorganization with respect to all
Mercantile Funds, all outstanding shares of the Mercantile Funds will have been
redeemed and cancelled in exchange for shares distributed by its Corresponding
Firstar Fund, and Mercantile will wind up its affairs and be deregistered as
investment company under the 1940 Act and dissolved under Maryland law.

     For further information about the transaction, see the Combined Proxy
Statement/Prospectus.

             Introductory Note to Pro Forma Financial Information

     The following unaudited pro forma information gives effect to the proposed
transfer of the assets and liabilities of the Mercantile Funds and Firstar
Stellar Funds, as applicable, to the Corresponding Firstar Funds, accounted for
as if each transfer had occurred as of April 30, 2000. In addition, each pro-
forma combined statement has been prepared based upon the proposed fee and
expense structure of the applicable Corresponding Firstar Fund. There are
multiple pro forma financial statements for the combination of the Mercantile
Treasury Money Market Portfolio, Firstar Stellar Treasury Fund and Firstar U.S.
Treasury Money Market Fund and the combination of the Mercantile Tax-Exempt
Money Market Portfolio, Firstar Stellar Tax-Free Money Market Fund and Firstar
Tax-Exempt Money Market Fund because it is possible that only the Mercantile
Portfolio shareholders or Firstar Stellar Fund shareholders will approve the
reorganization of their portfolio or fund with the corresponding Firstar Fund.
Therefore, the pro forma financial statements for the combined and individual
combinations are shown.

     The pro forma financial information should be read in conjunction with the
historical financial statements and notes thereto of the Mercantile Funds (and
Firstar Stellar Funds, as applicable) and Firstar Funds incorporated herein by
reference in this Statement of Additional Information. Each combination of the
above Mercantile Funds and Firstar Funds will be accounted for as a tax-free
reorganization.

                              GENERAL INFORMATION

     The Reorganization contemplates the transfer of substantially all of the
assets and liabilities of each Stellar Fund to a Corresponding Firstar Fund in
exchange for shares of designated classes of the Corresponding Firstar Fund.

     The Shares issued by a Firstar Fund will have an aggregate value equal to
the aggregate value of the shares of the respective corresponding Stellar Funds
that were outstanding immediately before the effective time of the
Reorganization.

     After the transfer of substantially all of their assets and liabilities in
exchange for the Firstar Fund shares, the Stellar Funds will distribute the
shares to their shareholders in liquidation of such Stellar Fund.  Each
shareholder owning shares of a particular Stellar Fund at the effective time of
the Reorganization will receive shares from its Corresponding Firstar Fund of
equal value, and will receive any unpaid dividends or distributions that were
declared before the effective time of the Reorganization on shares of the
Stellar Funds.  The Corresponding Firstar Fund will establish an account for
each former shareholder of the Stellar Funds reflecting the appropriate number
of shares distributed to the shareholder.  These accounts will be substantially
identical to the accounts maintained by Stellar Funds for each shareholder.
Upon completion of the Reorganization with respect to all Stellar Funds, all
outstanding shares of the Stellar Funds will have been redeemed and cancelled in
exchange for shares distributed by its Corresponding Firstar Fund, and Stellar
will wind up its affairs and be deregistered as investment company under the
1940 Act and dissolved under Massachusetts law.

     For further information about the transaction, see the Combined Proxy
Statement/Prospectus.

             Introductory Note to Pro Forma Financial Information

     The following unaudited pro forma information gives effect to the proposed
transfer of the assets and liabilities of the Stellar Funds and Mercantile
Mutual Funds, Inc., as applicable, to the Corresponding Firstar Funds, accounted
for as if each transfer had occurred as of April 30, 2000. In addition, each
pro-forma combined statement has been prepared based upon the proposed fee and
expense structure of the applicable Corresponding Firstar Fund. There are
multiple pro forma financial statements for the combination of the Mercantile
Treasury Money Market Portfolio, Firstar Stellar Treasury Fund and Firstar U.S.
Treasury Money Market Fund and the combination of The Mercantile Tax-Exempt
Money Market Portfolio, Firstar Stellar Tax-Free Money Market Fund and Firstar
Tax-Exempt Money Market Fund because it is possible that only the Mercantile
Portfolio shareholders or Firstar Stellar Fund shareholders will approve the
reorganization of their portfolio or fund with the corresponding Firstar Fund.
Therefore, the pro forma financial statements for the individual combinations
are shown.

     The pro forma financial information should be read in conjunction with the
historical financial statements and notes thereto of the Stellar Funds (and
Mercantile Mutual Funds, Inc., as applicable) and Firstar Funds incorporated
herein by reference in this Statement of Additional Information. Each
combination of the above Stellar Funds and Firstar Funds will be accounted for
as a tax-free reorganization.

     The unaudited Pro Forma Combined Statements of Assets and Liabilities,
     Statements of Operations, and Schedules of Portfolio Investments reflect
     the accounts of sixteen investment portfolios offered by Firstar Funds,
     Inc. ("the Firstar Funds"), fifteen investment portfolios offered by
     Mercantile Mutual Funds, Inc. ("the Mercantile Funds") and six investment
     portfolios offered by Firstar Stellar Funds ("the Stellar Funds") as if
     the proposed reorganization occurred as of and for the year ended April 30,
     2000. These statements have been derived from books and records utilized in
     calculating daily net asset value at April 30, 2000. Below are the fund
     names for the Firstar Funds (F), the Mercantile Funds (M) and the Stellar
     Funds (S) and the Surviving Funds. All of the Surviving Funds will be
     portfolios of the Firstar Funds. The designation (F), (S) or (M) in the
     Surviving Funds column indicates which Fund will be the accounting survivor
     of the reorganization.

NOTES TO THE PRO FORMA FINANCIAL STATEMENTS (Unaudited)


The Plan of Reorganization provides that at the time the reorganization becomes
effective (the "Effective Time of the Reorganization"), substantially all of the
assets and liabilities of the acquired funds will be transferred such that at
and after the Effective Time of Reorganization, substantially all of the assets
and liabilities of the acquired funds will become assets and liabilities of the
acquiring funds. In exchange for the transfer of assets and liabilities, the
acquiring funds will issue to the acquired funds full and fractional shares of
the designated classes of the acquiring funds, and the acquired funds will make
a liquidating distribution of such shares to its shareholders. The number of
shares of the acquiring funds so issued will be in equal value to the full and
fractional shares of the acquired funds that are outstanding immediately prior
to the Effective Time of Reorganization. At and after the Effective Time of
Reorganization, all debts, liabilities and obligations of the acquired funds
will attach to the acquiring funds and may thereafter be enforced against the
acquiring funds to the same extent as if they had been incurred by them. The pro
forma statements give effect to the proposed transfer described above.

Under the purchase method of accounting for business combinations under
generally accepted accounting principles, the basis on the part of the acquiring
funds of the assets of the acquired funds will be the fair market value of such
on the closing date of the transaction. The acquiring funds will recognize no
gain or loss for federal tax purposes on its issuance of shares in the
reorganization, and the basis to the acquiring funds of the assets of the
acquired funds received pursuant to the reorganization will equal the fair
market value of the consideration furnished, and costs incurred, by the
acquiring funds in the reorganization -- i.e., the sum of the liabilities
assumed, the fair market value of the acquiring funds shares issued, and such
costs. For accounting purposes, the Surviving Funds are the survivor of this
reorganization. The pro forma statements reflect the combined results of
operations of the acquired and acquiring funds. However, should such
reorganization be effected, the statements of operations of the acquiring funds
will not be restated for precombination period results of the corresponding
acquired funds.

The Pro Forma Combined Statements of Assets and Liabilities, Statements of
Operations, and Schedules of Portfolio Investments should be read in conjunction
with the historical financial statements of the Firstar Funds, Mercantile Funds
and Firstar Stellar Funds incorporated by reference in the Statement of
Additional Information.

The Firstar Funds, Mercantile Funds and Firstar Stellar Funds are each separate
portfolios of the Firstar Funds, Inc., Mercantile Mutual Funds, Inc. and the
Firstar Stellar Funds, which are registered as open-end management investment
companies under the Investment Company Act of 1940 (the "1940 Act").

2.   Service Providers
     -----------------

     Firstar Investment Research & Management Company, LLC (the "Advisor"), will
     serve as the combined Fund's investment advisor. Clay Finlay, Inc. will
     serve as the sub-advisor to the Firstar International Growth Fund. Firstar
     Mutual Fund Services, LLC (the "Administrator") will serve as the
     administrator, transfer agent and fund accountant to the Funds. Firstar
     Bank, N.A. will serve as the custodian to the Funds. Quasar Distributors,
     Inc. will serve as the distributor to the Funds.

3.   Organizational Expenses
     -----------------------

     Organizational costs of the funds that are not Surviving Funds cannot be
     carried over when being merged with another fund. Therefore, in the
     Statements of Assets and Liabilities, the organizational costs were
     reclassified against capital for the Non-Surviving Funds rather than being
     carried forward.

4.   Classes and Fees
     ----------------

          Mercantile Funds
          ----------------

     The Mercantile Funds have several classes of shares which have identical
     rights and privileges except with respect to fees paid under shareholder
     servicing and/or distribution plans, expenses allocable exclusively to each
     class of shares, voting rights on matters affecting a single class of
     shares, and the exchange privilege of each class of shares. Investor A
     shares are subject to a front-end sales charge. Investor B shares are
     subject to a contingent deferred sales charge (CDSC).

     constant basis to the maturity of the security. In addition, the Money
     Market Funds may not (a) purchase any instrument with a remaining maturity
     greater than thirteen months unless such instrument is subject to a demand
     feature, or (b) maintain a dollar-weighted average maturity which exceeds
     90 days.

     Securities of the Non-Money Market Funds are valued at market value. Short-
     term investments maturing in 60 days or less are valued at amortized cost,
     which approximates market value.

     Security transactions are accounted for on a trade date basis. Net realized
     gains or losses from sales of securities are determined by comparing the
     net sale proceeds to an identified cost basis. Interest income and expenses
     are recognized on the accrual basis. Dividends are recorded on the ex-
     dividend or as soon as information is available to the Funds. Discounts and
     premiums on securities are amortized over the life of the respective
     security. Discounts and premiums on securities with put provisions are
     amortized to the earlier of the put date or maturity.

PART C.  OTHER INFORMATION

Item 15.  Indemnification
          ---------------

         Article IX of Registrant's  Articles of Incorporation,  incorporated by
reference  as  Exhibit  (1)(a)  hereto,  provides  for  the  indemnification  of
Registrant's  directors  and  officers  to  the  full  extent  permitted  by the
Wisconsin Business Corporation Law and the Investment Company Act of 1940.

         Article VII of the By-laws of the Registrant, incorporated by reference
as Exhibit (2)(a) hereto, provides that officers and directors of the Registrant
shall be indemnified  by the Registrant  against  judgments,  penalties,  fines,
excise taxes,  settlements and reasonable expenses  (including  attorney's fees)
incurred in  connection  with a legal  action,  suit or  proceeding  to the full
extent permissible under the Wisconsin Business  Corporation Law, the Securities
Act of 1933 and the Investment Company Act of 1940.

         Registrant has obtained from a major insurance carrier a directors' and
officers' liability policy covering certain types of errors and omissions. In no
event will  Registrant  indemnify any of its  directors or officers  against any
liability  to which  such  person  would  otherwise  be subject by reason of his
willful  misfeasance,  bad faith,  gross negligence or reckless disregard of the
duties involved in the conduct of his or her office. Registrant will comply with
Rule 484  under the  Securities  Act of 1933 and  Release  No.  11330  under the
Investment Company Act of 1940 in connection with any indemnification.

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

         Indemnification  of the Registrant,  its affiliates,  their  respective
assigns and their respective officers, directors, employees, agents and servants
against  certain  losses is provided for in Section 7.2 of the  Internet  Access
Agreement with Firstar Trust Company incorporated herein by reference as Exhibit
(13)(ff).

         Indemnification   of  the   Registrant,   its   transfer   agent,   its

the  Securities Act of 1933,  against  certain losses is provided for in Section

employees and agents against certain losses is provided for in Section 13 of the
Retirement  Plan Order  Processing  Amendment to the  Operating  Agreement  with
Charles  Schwab & Co.,  Inc.,  The  Charles  Schwab  Trust  Company  and Firstar
Investment Research and Management Company, LLC incorporated herein by reference
to Exhibit (13)(pp).

         Indemnification  of the  Registrant,  its investment  adviser and their
directors, officers, employees and agents against certain losses is provided for

Firstar Investment Research and Management  Company,  LLC incorporated herein by
reference as Exhibit (13)(qq).

transfer agents against certain losses is provided for, respectively, in Section
6(a) of the Distribution Agreement,  incorporated by reference as Exhibit (7)(a)
hereto,  Section 11 of the  Custodian  Agreement,  incorporated  by reference as
