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 24, 2000 at the
offices of Mercantile's counsel, Drinker Biddle & Reath LLP, One Logan Square,
18th 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 July 11, 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").

  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

                                       1
<PAGE>

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 late November or
early December 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 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;

                                       2
<PAGE>

    (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 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.

                              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 24, 2000. If all necessary approvals are obtained, the proposed
reorganization will likely take place in late November or early December 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 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," and each, a "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.

                                       1

  Under the proposed agreement and plan of reorganization (the "Reorganization
Agreement"), 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
     that has investment objectives and policies 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.

  At the same time that the Mercantile Funds are reorganized into the Firstar
Funds, it is expected that the investment portfolios of 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 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. Consummation of the Stellar and Select
reorganizations is subject to numerous conditions described in the relevant
reorganization agreement, including approval by shareholders of Stellar and
Select. If the Reorganization Agreement is approved by Mercantile shareholders
at the Special Meeting, it is expected that the Mercantile reorganization will
be completed whether or not the Stellar reorganization and Select
reorganization are completed.

  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.

                                       2
<PAGE>

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 or Firstar 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:

   reorganization with respect to certain of these shareholders.

  Mercantile Fund shareholders who do not wish to be reorganized into the
Firstar Funds and have their Mercantile Fund shares exchanged for shares of a
corresponding Firstar Fund should redeem their shares prior to

                                       3
<PAGE>

the consummation of the reorganization. If you redeem your shares, you will
recognize a taxable gain or loss based on the difference between your tax
basis in the shares and the amount you receive for them. In addition, if you
redeem your shares prior to the reorganization and your shares are subject to
a contingent deferred sales load, your redemption proceeds will be reduced by
any applicable sales load.

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 front-end 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" in the accompanying Proxy/Prospectus for additional
information.

Meeting") of each of the Portfolios of Mercantile Mutual Funds, Inc. named

  Item 1 is described in the attached Combined Proxy Statement/Prospectus.
Your Directors 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
Mercantile Board of Directors. 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 Mercantile 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 Directors


                                          /s/ Jerry V. Woodham

                                          Jerry V. Woodham
                                          Chairman of the Board and 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, 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.

  At the Special Meeting, shareholders will be asked:

  .  To approve a proposed Agreement and Plan of Reorganization dated as of
     July 11, 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").

  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.

  Additional information is set forth in the Statement of Additional
Information dated October 7, 2000 relating to this Proxy/Prospectus and in the
prospectuses dated March 31, 2000, as supplemented, for the designated share
classes of the Mercantile Funds, which are incorporated herein by reference.

(the "SEC"), and is available without charge by calling or writing Mercantile

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

  The securities offered hereby have not been approved or disapproved by the
SEC or any state securities commission nor has the SEC or any state securities

projected to experience higher, lower or the same annualized per share total
operating expense ratios than the designated class of the corresponding

ensure that for the period from the applicable effective time of the
Reorganization through October 31, 2001 the total operating expense ratios for
each class of shares of each Firstar Fund will not exceed the pro forma after
waiver expense ratios in Table I-C. These fee waivers and expense

  The following table shows (i) the current annualized total expense ratio as
of April 30, 2000 of each of the Mercantile Funds, before and after fee
waivers and/or expense reimbursements; (ii) the annualized total expense ratio
of each of the Existing Firstar Funds (other than the Firstar U.S. Government
Securities Fund, Firstar Aggregate Bond Fund and Firstar National Municipal
Bond Fund, Institutional Shares of the Firstar U.S. Treasury Money Market Fund
and the Firstar Tax-Exempt Money Market Fund and Class Y Shares of the Firstar
Intermediate Bond Market 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, which had not
commenced operations as of the date of this Proxy/Prospectus), before and
after fee waivers, restated to reflect the expenses each Fund expects to incur
during the current fiscal year; and (iii) the pro forma annualized total
expense ratio of the Firstar U.S. Government Securities Fund, Firstar
Aggregate Bond Fund, Firstar National Municipal Bond Fund and each of the
Shell Firstar Funds or the combined portfolios consisting of a Mercantile Fund
and its corresponding Firstar Fund, as the case may be, before and after fee
waivers, as of April 30, 2000, based upon the fee arrangements and commitments
that will be in place upon consummation of the reorganization of the
Mercantile Funds into corresponding Firstar Funds.

  FIRMCO has committed to waive fees and reimburse expenses as needed to
ensure that for the period from the applicable effective time of the
Reorganization through October 31, 2001 the total operating expense ratios for
each class of shares of each Firstar Fund will not exceed the pro forma after
waiver expense ratios in this Table. These fee waivers and expense
reimbursements may be terminated at any time after October 31, 2001.

  Detailed pro forma expense information for each proposed reorganization is
provided below in "Comparison of Mercantile Funds and Firstar Funds--Fees and
Expenses."

                                    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 and in the prospectuses and
statements of additional information of Firstar and Mercantile.

  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 two weeks 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:

* It is expected that prior to the Reorganization certain shareholders for
  whom Firstar Bank, N.A. or its affiliates have investment discretion will
  have their Trust II Shares exchanged for shares of the Firstar Institutional
  Money Market Fund; however, this exchange may occur after the Reorganization
  with respect to certain of these shareholders.

  The Reorganization is expected to occur in late November or early December
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 Reorganization--Description of the
Reorganization Agreement" below.

  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 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 following chart summarizes the investment objective of (i) each of the
Mercantile Funds, that is reorganizing into an existing Firstar Fund, and (ii)

  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 each of the Firstar Shell Funds has 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
"Investment Objectives, Limitations and Certain Significant Investment
Policies of the Reorganizing Mercantile Funds and Corresponding Firstar Funds"
below.

  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 and certain
non-fundamental 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 "Other Information Relating to the Stellar Treasury Fund" below.

  FIRMCO currently serves as the investment 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-

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

Shares will have total operating expense ratios (after fee waivers and/or
expense reimbursements) which are higher after the Reorganization. For a more
detailed summary of fees and expenses, see "Fee and Expenses" below.

  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 "Shareholder Transactions and Services of
the Firstar Funds and the Corresponding Mercantile Funds" below. 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.

  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; (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, with
respect to the Firstar Funds, 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.

                                      13
<PAGE>

  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 the same as or similar to those of investing in its
corresponding Reorganizing Mercantile Fund. The reorganization of certain
Mercantile Funds into Existing Firstar Funds will expose the Shareholders of
the Reorganizing Mercantile Funds to the following additional principal risk
factors (capitalized terms are described in the table that follows this
discussion).

capitalization stocks, small-capitalization stocks    Cap Index Funds
tend to carry greater risk and exhibit greater price
volatility because their businesses may not be well   Mercantile Small Cap Equity and
established. In addition, some smaller companies may  Small Cap Equity Index Portfolios
have specialized or limited product lines, markets

affect Missouri. Missouri's economy is largely        Bond Portfolio
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

subdivisions have encountered financial
difficulties.

mid- 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).

                              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.

  Shareholders of different Mercantile Funds and different classes of each
such Fund will be affected differently by the Reorganization. Some Firstar
Funds have different operating expenses and investment policies than their
corresponding Mercantile Fund. For more information on these differences,
please see "Comparison of Mercantile Funds and Firstar Funds" and "Expense
Summaries of the Mercantile Funds and the Corresponding Firstar Funds" below.

  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 applicable 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 applicable
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 Mercantile Fund prior to the
applicable 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 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. An
application requesting relief with respect to Section 17(a) of the 1940 Act
has been filed with the SEC, and it is expected that the SEC will issue an
order granting such relief prior to the Reorganization.

  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.

  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; (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

                                      24
<PAGE>

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" above and "Fees and
Expenses" below 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 for the period from the applicable effective
time of the Reorganization through 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 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.

  Federal Income Tax Considerations. Each Firstar Fund and each Mercantile
Fund intends to qualify as of the applicable 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 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 generally in this section and
are followed by a more detailed Fund-by-Fund analysis below. 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--Generally. 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 the 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 respective agencies and instrumentalities. The Firstar Tax-Exempt Money
Market Fund is a diversified portfolio under the 1940 Act while the Mercantile
Tax-Exempt Money 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 "Other Information
Relating to the Stellar Treasury Fund" below for a complete description of the
investment objective, policies and restrictions of the Stellar Treasury Fund.

  Reorganizing Bond Funds--Generally. 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 Brothers 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.

                                      43
<PAGE>

  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--Generally. 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 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 65% 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 total 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.

  Fund-by-Fund Analysis. This Fund-by-Fund analysis provides additional
information concerning 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 section. 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

                                      44
<PAGE>

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 Section. 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: Seeks to provide a high level
      of 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 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 "Other Information Relating to
the Stellar Treasury Fund" below.

  Mercantile Treasury Money Market Portfolio/Firstar U.S. Treasury Money
Market Fund. Each of the Mercantile Treasury Money Market Portfolio and the
Firstar U.S. Treasury Money Market 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. 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
or 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. Each of
the Mercantile Treasury Money Market Portfolio and the Stellar Treasury 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. 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. 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: Each of the Mercantile Money Market Portfolio and the Firstar Money
Market 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. 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 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.


                                      46
<PAGE>

  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 and other types of entities or by investment
companies, or they may be issued or guaranteed by the U.S. Government and its
agencies and instrumentalities or political subdivisions. 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.

  Each of the Mercantile Tax-Exempt Money Market Portfolio and the Firstar
Tax-Exempt Money Market 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. 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 those 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.

  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 debt 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,
which are exempt from federal income taxes and with remaining maturities of 13
months or less. For purposes of this fundamental policy, municipal securities
that are subject to the federal alternative minimum income tax are considered
taxable. 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, beneficial interests in trusts and partnership
interests.

                                      47
<PAGE>

  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.

  (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/Credit 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 Portfolio 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 to
eligible rated securities at the time of purchase. 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., those rated
A or higher by S&P or Moody's) or unrated debt obligations determined to be of
comparable quality to eligible rated securities at the time of purchase. The
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/Credit 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., those rated 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

                                      48
<PAGE>

of S&P or Moody's. The effective dollar-weighted average portfolio maturity of
the 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 total 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. Both Funds may enter into futures contracts and related options, but
only the Firstar Intermediate Bond Market Fund may buy and sell futures
contracts and related options on foreign exchanges or boards of trade.

5.  Mercantile Bond Index Portfolio/Firstar Aggregate Bond Fund

  Investment Objectives:

  (a) Mercantile Bond Index Portfolio: Seeks to provide investment results
      that, before the 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 a similar investment objective and
substantially the same investment 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 before expenses, 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.

  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

                                      49
<PAGE>

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 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., those rated
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, primarily bonds (at least 65% under normal market conditions). At
least 80% of its total assets will be invested in municipal securities 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 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 reverse
repurchase agreements and options, although the Fund

                                      50
<PAGE>

does not intend to invest in options 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/Credit Bond Index. Except for convertible securities, the
Fund will purchase only fixed-income securities rated investment grade or
unrated obligations determined to be of comparable quality.

                                      51
<PAGE>

  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 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 Fund 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
Portfolio 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. Both Funds may
enter into futures contracts and related options, but only the Firstar
Balanced Growth Fund may buy and sell futures contracts and related options on
foreign exchanges or boards of trade. 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.

  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

                                      52
<PAGE>

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 stock 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 in an 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 stock 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. In addition, the Firstar Equity Index Fund, unlike the
Mercantile Equity Index Portfolio, may buy and sell futures contracts and
related options on foreign exchanges or boards of trade.

  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
Portfolio 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.

  (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 primary 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 will invest in preferred stocks convertible into common
stocks only if they provide a

                                      53

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 & Income Fund, unlike the Mercantile Growth &
Income Equity 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 Portfolio may invest. The Firstar Growth & 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 common 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 65% of its total assets in
equity securities of large-sized companies. 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.


                                      54
<PAGE>

  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 grade bonds, notes and debentures, although the Firstar
Growth Fund will invest in these securities only 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 Portfolio 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.

                                      55
<PAGE>

  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 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. Both Funds
may enter into futures contracts and related options, but only the Firstar
Emerging Growth Fund may buy and sell futures contracts and related options on
foreign exchanges or boards of trade.

  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 Portfolio 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

                                      56
<PAGE>

  (b) Firstar Core International Equity Fund: Seeks to provide maximum, long-
      term total return consistent with reasonable risk to 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 securities of companies located in the
developed countries of Western Europe and Japan, although the Portfolio 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

                                      57
<PAGE>

such investments to those securities issued by "money market" funds which
invest in securities in which the Portfolio 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.

Other Information Relating to the Stellar Treasury Fund.

  Investment Objective

  The 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.

  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.

  .  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

                                      58
<PAGE>

     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. The investment policies and
limitations of the Fund may not be changed by the Board of Trustees of Stellar
without approval of shareholders.

  The Fund may follow non-fundamental operational policies that are more
restrictive than the fundamental investment limitations set forth in this
section 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.

  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.

                                      59
<PAGE>

  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.

  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 section, "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.

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

                                      60
<PAGE>

   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% of the value
   of total assets at the time of the pledge.

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 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
  Funds 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

  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

                                      68
<PAGE>

  higher sales load in case you do not purchase the full amount indicated on

  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

  spouse purchasing securities for his, her or their own account, or the

  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 at the time of the exchange. 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 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 Retail A Shares of a
Money Market Fund acquired in an exchange of Retail B Shares will be subject
to a contingent deferred sales charge upon redemption. 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 Firstar Bank,
N.A. 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

                                      76
<PAGE>

with a higher sales charge, 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 Investor A Shares and Firstar Retail A Shares, the
applicable front-end sales charge.

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

  The NAV for each of Mercantile's Equity Funds and Firstar's Equity and Bond
Funds is determined on any day that the New York Stock Exchange (the
"Exchange") is open for business. The NAV for each of Mercantile's Money
Market and Bond Funds and Firstar's Money Market Funds is determined on any
day that both the Exchange and the Federal Reserve Banks' Fedline System is
open.

  An investor's order for the purchase of shares is priced at the next NAV
calculated after the order is received. An investor's order for redemption of
shares is priced at the next NAV calculated after the shares are properly
tendered for redemption.

purpose of these tables is to assist shareholders in understanding the various
costs and expenses that investors in these Funds 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
Funds. 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
for the period from the applicable effective time of the Reorganization
through October 31, 2001 total operating expense ratios will not exceed the
pro forma after waiver expense ratios. These fee waivers and expense
reimbursements may be terminated at any time after October 31, 2001 at
FIRMCO's discretion.

 +  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 contemporaneously 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. The failure of the Firstar
    Stellar Treasury Fund to reorganize into the Firstar U.S. Treasury Money
    Market Fund as expected will not affect the Reorganization of the
    Mercantile Treasury Money Market Portfolio into the Firstar U.S. Treasury
    Money Market Fund and will have no material affect on the above expense
    estimates.
 ++ 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:

(4)  "Other Expenses" for the Funds are expected to be less than the amounts

(5)  As a result of fee waivers and/or expense reimbursements, 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. FIRMCO has
     committed to waiving/reimbursing fees as needed to ensure that for the
     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the

 *  In the Reorganization, holders of each class of shares of the Mercantile
    Money Market Portfolio will receive Retail A Shares of the Firstar Money
    Market Fund.
 +  It is expected that prior to the Reorganization certain shareholders for
    whom Firstar Bank, N.A. or its affiliates have investment discretion will
    have their Trust II Shares exchanged for shares of the Firstar
    Institutional Money Market Fund; however, this exchange may occur after
    the Reorganization with respect to certain shareholders.
(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.
(2)  A fee of $12.00 is charged for each wire redemption and $15.00 for each
     non-systematic withdrawal from a retirement account for which Firstar
     Bank, N.A. is a custodian.
(3)  Management Fees (after waivers) would be:

   Combined Fund Pro Forma.......................... 0.01%
</TABLE>

(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.

(6)  As a result of fee waivers and/or expense reimbursements, 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. FIRMCO has
     committed to waiving/reimbursing fees as needed to ensure that for the
     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the
     pro forma after waiver expense ratios. These fee waivers and expense
     reimbursements may be terminated at any time after October 31, 2001 at
     FIRMCO's discretion.

 *  The Firstar Stellar Tax-Free Money Market Fund is expected to reorganize
    into the Firstar Tax-Exempt Money Market Fund contemporaneously with the
    Reorganization. The reorganization of the Firstar Stellar Tax-Free Money
    Market Fund into the Firstar Tax-Exempt Money Market Fund and the
    Reorganization of the Mercantile Tax-Exempt Money Market Portfolio into
    the Firstar Tax-Exempt Money Market Fund will occur only if the
    shareholders of the appropriate Funds approve each transaction. The
    failure of the Firstar Stellar Tax-Free Money Market Fund to reorganize
    into the Firstar Tax-Exempt Money Market Fund as expected will not affect
    the Reorganization of the Mercantile Tax-Exempt Money Market Portfolio
    into the Firstar Tax-Exempt Money Market Fund and will have no material
    affect on the above expense estimates.
 ++ Institutional Shares will not be issued until the applicable effective
    time of the Reorganization.

     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the

 +  In the Reorganization, holders of Trust Shares of the Mercantile U.S.
    Government Securities Portfolio and holders of Class A Shares and Class B
    Shares of the Firstar Stellar U.S. Government Income 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 U.S. Government Securities Fund.
    Holders of Institutional Shares of the Mercantile U.S. Government
    Securities Portfolio will receive Class Y Shares 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 contemporaneously 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 occur only
    if the shareholders of the appropriate Funds approve each transaction. The
    failure of the Firstar Stellar U.S. Government Income Fund to reorganize
    into the Firstar U.S. Government Securities Fund as expected will not
    affect the Reorganization of the Mercantile U.S. Government Securities
    Portfolio into the Firstar U.S. Government Securities Fund and will have
    no material affect on the above expense estimates.
(1)  The Firstar U.S. Government Securities Fund has not yet commenced
     operations. Upon consummation of the Reorganization, 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 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 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)  "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 fee waivers and/or expense reimbursements, 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. FIRMCO has
     committed to waiving/reimbursing fees as needed to ensure that for the
     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the
     pro forma after waiver expense ratios. These fee waivers and expense
     reimbursements may be terminated at any time after October 31, 2001 at
     FIRMCO's discretion.

     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 the 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 contemporaneously 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 occur only
    if the shareholders of the appropriate Funds approve each transaction. The
    failure of the Firstar Stellar U.S. Government Income Fund to reorganize
    into the Firstar U.S. Government Securities Fund as expected will not
    affect the Reorganization of the Mercantile U.S. Government Securities
    Portfolio into the Firstar U.S. Government Securities Fund and will have
    no material affect on the above expense estimates.
(1)  The Firstar U.S. Government Securities Fund has not yet commenced
     operations. Upon consummation of the Reorganization, 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 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 distribution
     (12b-1) fees for Class A Shares and Class B Shares for the current fiscal
     year.
(6)  The total of all distribution (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 Retail A Shares. The Fund does not expect to
     pay distribution (12b-1) fees with respect to 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:

     Operating Expenses are expected to be less than the amounts shown above.

     annual fees and expenses of the Funds at a certain level. FIRMCO has
     committed to waiving/reimbursing fees as needed to ensure that for the
     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the

 *  In the Reorganization, holders of Trust Shares of the Mercantile
    Intermediate Corporate Bond Portfolio will receive Institutional Shares of
    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 applicable effective time of
    the Reorganization.
(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.
(2)  Management Fees (after waivers) would be:

(3)  The total of all distribution (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 Retail A Shares. The Fund does not expect to
     pay distribution (12b-1) fees with respect to 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.

     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the

 *  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. The failure of either Mercantile
    Fund to reorganize into the Firstar Aggregate Bond Fund will not affect
    the Reorganization of the other Mercantile Fund into the Firstar Aggregate
    Bond Fund and will have no material affect on the above expense estimates.
(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 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 distribution (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 Retail A Shares. The Fund does not expect to
    pay distribution (12b-1) fees with respect to 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.

     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. FIRMCO has
     committed to waiving/reimbursing fees as needed to ensure that for the
     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the
     pro forma after waiver expense ratios. These fee waivers and expense
     reimbursements may be terminated at any time after October 31, 2001 at

    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.
(1)  The Firstar Missouri Tax-Exempt Bond Fund has not yet commenced
     operations. The Firstar Missouri Tax-Exempt Bond Fund will continue the
     operations of the Mercantile Missouri Tax-Exempt Bond Portfolio upon
     consummation of the Reorganization relating to those Funds.
(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.

     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

     committed to waiving/reimbursing fees as needed to ensure that for the
     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the
     pro forma after waiver expense ratios. These fee waivers and expense
     reimbursements may be terminated at any time after October 31, 2001 at

 +  In the Reorganization, holders of Trust Shares of the Mercantile National
    Municipal Bond Portfolio and holders of Class A Shares and Class B Shares
    of 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 contemporaneously 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 occur only if the
    shareholders of the appropriate Funds approve each transaction. The
    failure of the Firstar Stellar Insured Tax-Free Bond Fund to reorganize
    into the Firstar National Municipal Bond Fund as expected will not affect
    the Reorganization of the Mercantile National Municipal Bond Portfolio
    into the Firstar National Municipal Bond Fund and will have no material
    affect on the above expense estimates.
(1)  The Firstar National Municipal Bond Fund has not yet commenced
     operations. Upon consummation of the Reorganizations, 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
     distribution (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

    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 contemporaneously 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 occur only if the
    shareholders of the appropriate Funds approve each transaction. The
    failure of the Firstar Stellar Insured Tax-Free Bond Fund to reorganize
    into the Firstar National Municipal Bond Fund as expected will not affect
    the Reorganization of the Mercantile National Municipal Bond Portfolio
    into the Firstar National Municipal Bond Fund and will have no material
    affect on the above expense estimates.
(1)  The Firstar National Municipal Bond Fund has not yet commenced
     operations. Upon consummation of the Reorganization, 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.
(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 distribution (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 Retail A Shares. The Fund does not expect to
     pay distribution (12b-1) fees with respect to 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:

(8)  As a result of fee waivers and/or expense reimbursements, 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. FIRMCO has
     committed to waiving/reimbursing fees as needed to ensure that for the
     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the
     pro forma after waiver expense ratios. These fee waivers and expense
     reimbursements may be terminated at any time after October 31, 2001 at

 *  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 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:

   Combined Fund Pro Forma.......................... 0.71%

(4)  The total of all distribution (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 Retail A Shares. The Fund does not expect to
     pay distribution (12b-1) fees with respect to 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 fee waivers and/or expense reimbursements, 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

     committed to waiving/reimbursing fees as needed to ensure that for the

    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 these Funds.
(2)  This amount applies if you sell your shares in the first year after

     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 0.72% for the Combined Fund Pro

    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 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 distribution (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 Retail A Shares. The Fund does not expect to
     pay distribution (12b-1) fees with respect to 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

 *  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.
(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

     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 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 distribution (12b-1) fees and shareholder servicing fees
     may not exceed, in the aggregate, the annual rate of 0.25% of the Fund's

    Firstar Small Cap Index Fund, and holders of Investor A Shares of the
    Mercantile Small Cap Equity Index Portfolio will receive Retail A Shares
    of the Firstar Small Cap Index Fund.
(1)  The Firstar Small Cap Index Fund has not yet commenced operations. The
     Firstar Small Cap Index Fund will continue the operations of the
     Mercantile Small Cap Equity Index Portfolio upon consummation of the
     Reorganization relating to those Funds.
(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
     which Firstar Bank, N.A. is custodian.
(3)  Management Fees (after waivers) would be 0.34% for the Combined Fund Pro
     Forma.
(4)  The total of all distribution (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 Retail A Shares. The Fund does not expect to
     pay distribution (12b-1) fees with respect to 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.

 *  In the Reorganization, holders of Investor A Shares and Investor B Shares
    of the Mercantile International Equity Portfolio will receive Retail A
    Shares and Retail B Shares, respectively, of the Firstar Core
    International Equity Fund.
(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 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%
</TABLE>

(5)  The Firstar Core International Equity Fund and Combined Fund Pro Forma do
     not intend to pay distribution (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:

(7)  As a result of fee waivers and/or expense reimbursements, 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. FIRMCO has
     committed to waiving/reimbursing fees as needed to ensure that for the
     period from the applicable effective time of the Reorganization through
     October 31, 2001, Total Fund Operating Expense ratios will not exceed the
     pro forma after waiver expense ratios. These fee waivers and expense
     reimbursements may be terminated at any time after October 31, 2001 at
     FIRMCO's discretion.

  Total Fund Operating Expenses (after waivers) would be:

  Performance Comparisons of the Existing Firstar Funds and Corresponding
Mercantile Funds.

  The following section provides a comparison of the total return performance
of the Reorganizing Mercantile Funds and the Existing Firstar Funds and is
followed by the Management Discussion of Firstar Fund Performance which was
included in the Firstar Annual Report for the fiscal year ended October 31,
1999.

  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 July 31, 2000. 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.

                  Management Discussion of Fund Performance.

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.

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.

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.

                                      145
<PAGE>

  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

                                      147
<PAGE>

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.

Growth Fund

  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

                                      149
<PAGE>

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.

  Effective at the close of business on 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
4.50% 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

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

                                      152
<PAGE>

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.

  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 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 "Shareholder
Transactions and Services of the Firstar Funds and the Corresponding

                                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.

  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 $6,000.

  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; 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.

  (f) Mercantile shall promptly cancel on its books all of the shares
(including, without limitation, any treasury shares) of each Mercantile Fund

  3. Calculations.

  (a) The number of each class of Firstar Fund Shares of each Existing and
Shell Firstar Fund issued to its Corresponding Mercantile Fund pursuant to
Section 2(b) hereof will be determined as follows:

    (i) With respect to the Mercantile Treasury Money Market Portfolio, the
  value (determined as of the Applicable Valuation Time (as hereinafter

  Liabilities that are assumed, at the Applicable Effective Time of the
  Reorganization (as hereinafter defined) and that are attributable to either

  shall be divided by the net asset value of one Institutional Share of its
  Corresponding Firstar Fund that is to be delivered with respect thereto.

    (ii) With respect to the Mercantile Money Market Portfolio, the value
  (determined as of the Applicable Valuation Time (as hereinafter defined))
  of such Mercantile Fund's Assets that are conveyed, less the Liabilities

    thereto; and

      (B) The value (determined as of the Applicable Valuation Time (as
    hereinafter defined)) of such Mercantile Fund's Assets that are
    conveyed, less the Liabilities that are assumed, at the Applicable
    Effective Time of the Reorganization (as hereinafter defined) and that
    are attributable to either Trust or Trust II Shares of such Mercantile
    Fund shall be divided by the net asset value of one Institutional Share
    of its Corresponding Firstar Fund that is to be delivered with respect
    thereto.

    (iv) With respect to the Conning Money Market Portfolio, the value
  (determined as of the Applicable Valuation Time (as hereinafter defined))
  of such Mercantile Fund's Assets that are conveyed, less the Liabilities
  that are assumed, at the Applicable Effective Time of the Reorganization
  (as hereinafter defined) shall be divided by the net asset value of one
  Share of its Corresponding Firstar Fund that is to be delivered with
  respect thereto;

    (v) With respect to all the other Mercantile Funds:

      (A) The value (determined as of the Applicable Valuation Time (as
    hereinafter defined)) of such Mercantile Fund's Assets that are
    conveyed, less the Liabilities that are assumed, at the Applicable
    Effective Time of the Reorganization (as hereinafter defined) and that
    are attributable to Investor A Shares of such Mercantile Fund shall be

    Corresponding Firstar Fund that is to be delivered with respect
    thereto;

      (C) The value (determined as of the Applicable Valuation Time (as
    hereinafter defined)) of such Mercantile Fund's Assets that are

                                      I-4
<PAGE>

    Effective Time of the Reorganization (as hereinafter defined) and that
    are attributable to Institutional Shares of such Mercantile Fund shall
    be divided by the net asset value of one Class Y Share of its
    Corresponding Firstar Fund that is to be delivered with respect
    thereto; and

      (D) The value (determined as of the Applicable Valuation Time (as

    Corresponding Firstar Fund that is to be delivered with respect
    thereto.

  (b) The net asset value of each class of Firstar Fund Shares shall be
computed at the Applicable Valuation Time (as hereinafter defined) in the
manner set forth in such Firstar Fund's then current prospectus under the
Securities Act of 1933, as amended (the "1933 Act"). The net asset value of
shares of each class of a Mercantile Fund shall be computed at the Applicable
Valuation Time in the manner set forth in such Mercantile Fund's then current
prospectus under the 1933 Act.

  4. Valuation of Assets.

  (a) With respect to each Mercantile 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 Mercantile Fund Assets to be transferred to the Firstar
Funds shall be computed by Mercantile and shall be subject to adjustment by
the amount, if any, agreed to by Mercantile and the respective Mercantile
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 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 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

                                      I-5
<PAGE>

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.

  5. Valuation Times. Subject to Section 4(b) hereof, the valuation time with
respect to the Existing Firstar Funds and the Reorganizing Mercantile Funds
shall be 4:00 p.m., Eastern Time, on November 24, 2000, or such earlier or
later date and time as may be mutually agreed in writing by an authorized
officer of each of the parties (the "First Valuation Time"). Subject to
Section 4(b) hereof, the valuation time with respect to the Shell Firstar
Funds and the Continuing Mercantile Funds shall be 4:00 p.m., Eastern Time, on
December 8, 2000, or such earlier or later date and time as may be mutually
agreed in writing by an authorized officer of each of the parties (the "Second
Valuation Time" and, together with the First Valuation Time, each an
"Applicable Valuation Time"), provided that the Second Valuation Time shall be
no less than one week 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
Mercantile, accurate appraisal of the value of the net assets of a Firstar
Fund or a Mercantile 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 Mercantile Funds is practicable in the judgment of
Firstar and Mercantile.

  6. Effective Time of the Reorganization.

  (a) Delivery by each Reorganizing Mercantile Fund of its respective Assets
to its Corresponding Firstar Fund, delivery by such Corresponding Firstar Fund
of its respective Firstar Fund Shares to such Reorganizing Mercantile Fund,
and liquidation of each such Reorganizing Mercantile Fund, in each case,
pursuant to Section 2 hereof, shall occur at the opening of business on the
next business day following the First Valuation Time (or on such other date
following the First 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 taken shall be the "Applicable Effective Time of the
Reorganization" with respect to the Existing Firstar Funds and the
Reorganizing Mercantile Funds. To the extent any Assets of any Reorganizing
Mercantile Fund are, for any reason, not transferred to its Corresponding
Firstar Fund at the Applicable Effective Time of the Reorganization with
respect to such Funds, Mercantile shall cause such Assets to be transferred in
accordance with this Agreement at the earliest practicable date thereafter.

  (b) Delivery by each Continuing Mercantile Fund of its respective Assets to
its Corresponding Firstar Fund, delivery by each such Corresponding Firstar
Fund of its respective Firstar Fund Shares to such Continuing Mercantile Fund,
and the liquidation of each such Continuing Mercantile Fund, in each case,
pursuant to Section 2 hereof, shall occur at the opening of business on the
next business day following the Second Valuation Time (or on such other date
following the 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 taken shall be the "Applicable Effective Time of
the Reorganization" with respect to the Shell Firstar Funds and the Continuing
Mercantile Funds. To the extent any Assets of any Continuing Mercantile Fund
are, for any reason, not transferred at the Applicable Effective Time of the
Reorganization with respect to such Funds, Mercantile shall cause such Assets
to be transferred in accordance with this Agreement at the earliest
practicable date thereafter.

  (c) Prior to the Applicable Effective Time of the Reorganization with
respect to each Mercantile Fund and its Corresponding Firstar Fund, Firstar
and Mercantile shall execute and file Articles of Transfer, effective as of

Firstar Fund, with respect to the transactions contemplated by this Agreement
with the Department of Assessments and Taxation of the State of Maryland (the
"Department of Assessments").

  7. Termination of Mercantile. Promptly following the Applicable Effective
Time of the Reorganization with respect to the Shell Firstar Funds and their
Corresponding Mercantile Funds, Mercantile shall file an application pursuant
to Section 8(f) of the 1940 Act for an order declaring that Mercantile has
ceased to be an investment company; provided that until such order is granted,
Mercantile shall continue to comply with all of its obligations as a
registered investment company under the 1940 Act and under any and all other
applicable state and federal securities laws (including, in the case of each
of the foregoing, the rules and regulations thereunder). Mercantile shall,
promptly after the Applicable Effective Time of the Reorganization with
respect to the Shell Firstar Funds and their Corresponding Mercantile Funds,
file any final regulatory reports, including, but not limited to, any Form N-
SAR and Rule 24f-2 Notice, with respect to such Mercantile Fund(s). All
reporting and other obligations of Mercantile shall remain the exclusive
responsibility of Mercantile up to and including the date on which such
Mercantile Fund is deregistered and dissolved. In addition, subject to the
provisions of Section 28 hereof, promptly following the Applicable Effective
Time of the Reorganization with respect to the Shell Firstar Funds and their
Corresponding Mercantile Funds, Mercantile shall take all other steps
necessary and proper to effect its complete dissolution. Without limiting the
generality of the foregoing, (a) the affairs of Mercantile shall be
immediately wound up, its contracts discharged and its business liquidated;
and (b) at an appropriate time as determined by Mercantile, upon the advice of
counsel, Mercantile shall file Articles of Dissolution with the Department of

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 24, 2000 at the offices of Stellar's special counsel,
Drinker Biddle & Reath LLP, One Logan Square, 18th 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 June 7, 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.

  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.

                                       1
<PAGE>

  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 late November or early
December 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, each of which 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, each of
which 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 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;

                                       2
<PAGE>

    (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.

Stellar Funds named above, more than one Proxy Ballot accompanies these

                              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 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 24, 2000. If all necessary approvals are obtained, the proposed
reorganization will likely take place in late November or early December 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.

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:

 * The Stellar Fund's investment objectives and policies are expected to
   continue following the proposed reorganization.
** The Mercantile Fund's investment objectives and policies are expected to
   continue following the proposed reorganization.

  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. Consummation of the
Mercantile and Select reorganizations is subject to numerous conditions
described in the relevant reorganization agreement, including approval by the
shareholders of Mercantile and Select. If the Reorganization Agreement is
approved by the Stellar shareholders at the Special Meeting, it is expected
that the Stellar reorganization will be completed whether or not the
Mercantile reorganization or Select reorganization are completed.

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

                                       2
<PAGE>

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.

  Stellar Fund shareholders who do not wish to be reorganized into the Firstar
Funds and have their Stellar Fund shares exchanged for shares of a
corresponding Firstar Fund should redeem their shares prior to the
consummation of the reorganization. If you redeem your shares, you will
recognize a taxable gain or loss based on the difference between your tax
basis in the shares and the amount you receive for them. In addition, if you
redeem your shares prior to the reorganization and your shares are subject to
a contingent deferred sales load, your redemption proceeds will be reduced by
any applicable sales load.

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 front-end 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" in the accompanying Proxy/Prospectus for additional
information.

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

counsel, Drinker Biddle & Reath LLP, One Logan Square, 18th & 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; 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

                                       1

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

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

  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, 18th & Cherry Streets, Philadelphia, Pennsylvania, on
November 24, 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
     June 7, 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 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

                                       1
<PAGE>

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 dated October 7, 2000 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 (and September 14,
2000 (as supplemented), with respect to Institutional Shares of the Firstar
U.S. Treasury Money Market Fund and Firstar Tax-Exempt Money Market Fund), for
the designated share classes, and September 18, 2000 (as supplemented), 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 October 23, 2000.

  The securities offered hereby have not been approved or disapproved by the
Securities and Exchange Commission or any state securities commission nor has
the Securities and Exchange Commission or any state securities commission
passed upon the accuracy or adequacy of this Proxy/Prospectus. Any
representation to the contrary is a criminal offense.

  Shares of Stellar and Firstar are not deposits or obligations of, or
guaranteed or endorsed by, Firstar Corporation, Firstar Investment Research &
Management Company, LLC or any of their affiliates or any other bank. Such
shares are not insured by the U.S. government, the Federal Deposit Insurance
Corporation, the Federal Reserve Board or any other government agency. Mutual
fund shares involve certain investment risks, including the possible loss of
principal. The distributor of Stellar and Firstar is Quasar Distributors, LLC.

  Money market funds seek to maintain a net asset value of $1.00 per share. An
investment in a money market fund is neither insured nor guaranteed by the
U.S. government. There can be no assurance that a money market fund will be
able to maintain a stable net asset value of $1.00 per share.

  The following table shows (i) the current annualized total expense ratio as
of April 30, 2000 of each of the Stellar Funds, before and after fee waivers;
(ii) the annualized total expense ratio of each of the Existing Firstar Funds

Proxy/Prospectus and Institutional Shares of the Firstar U.S. Treasury Money
Market Fund and Firstar Tax-Exempt Money Market Fund, which were not offered
as of the date of this Proxy/Prospectus), before and after fee waivers
restated to reflect the expenses each Fund expects to incur during the current
fiscal year; and (iii) the pro forma annualized total expense ratio of the
Shell Firstar Funds or the combined portfolios consisting of a Stellar Fund
and its corresponding Firstar Fund, as the case may be, before and after fee
waivers, as of April 30, 2000, based upon the fee arrangements and commitments
that will be in place upon consummation of the Reorganization.

  FIRMCO has committed to waive fees and reimburse expenses as needed to

                                    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, and in the prospectuses and
statements of additional information of Firstar and Stellar.

  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 two weeks 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 late November or early December
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 Reorganization--Description of the
Reorganization Agreement" below.

  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.

  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 Generally"
and "Comparison of Stellar Funds and Firstar Funds--Fund-by-Fund Analysis"
below.

  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

                                       8

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.

  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.

--------
* 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 and/or expense reimbursements)
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
and/or expense reimbursements) 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 and/or expense reimbursements)
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 and/or expense reimbursements) that are lower after the
Reorganization; and (v) Stellar Class Y shareholders will have total operating
expense ratios (after fee waivers and/or expense reimbursements) 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. For a more
detailed summary of fees and expenses, see "Comparison of Stellar Funds and
Firstar Funds--Fees and Expenses" below.

  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 Services of the Firstar Funds and the Corresponding Stellar Funds" and
"Comparison of Stellar Funds and Firstar Funds--Share Structure" below.

  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 with respect to the Firstar Funds, 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 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--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 their respective classes 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 of its corresponding Stellar Fund. Accordingly, an investment
in an Existing Firstar

                                      10

Fund involves risks that are the same as or similar to those of investing in
its corresponding Stellar Fund. The Reorganization of certain Stellar Funds
into Existing Firstar Funds will expose the shareholders of the Reorganizing
Stellar Funds to the following additional principal risk factors (capitalized
terms are defined in the table following the chart):

Municipal Government Risk--The ability of a state or  Firstar Tax-Exempt Money Market,
local government issuer to make payments can be       Ohio Tax-Exempt Money Market and
affected by many factors, including economic          National Municipal Bond Funds
conditions, the flow of tax revenues and changes in   Stellar Tax-Free Money Market,
the level of federal, state or local aid. Some        Ohio Tax-Free Money Market and
municipal securities are payable only from limited    Insured Tax-Free Bond Funds
revenue sources or by private entities.
--------------------------------------------------------------------------------
Non-Diversification Risk--The Fund is non-            Firstar Ohio Tax-Exempt Money
diversified, which means that it can invest a large   Market and Science & Technology
percentage of its assets in a small number of         Funds

state or local government or authority to acquire     Stellar Tax-Free Money Market and
land and a wide variety of equipment and facilities.  Insured Tax-Free Bond Funds

repurchase agreements in which banks, broker dealers  Securities Fund
and other financial institutions sell securities to   Stellar Treasury Fund
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 Fund          Firstar Tax-Exempt Money Market
purchases may be backed by letters of credit issued   Fund

effect on the Fund's portfolio securities.
--------------------------------------------------------------------------------
Investment in Ohio Risk--Ohio's economy is largely    Firstar Ohio Tax-Exempt Money
composed of manufacturing which is concentrated in    Market Fund
the automobile sector and other durable goods. The    Stellar Ohio Tax-Free Money
exposure to these industries, particularly the auto   Market Fund
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 state 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 invest more than  Firstar Ohio Tax-Exempt Money
25% of its total assets in securities credit-         Market Fund
enhanced by banks. Any bankruptcy, receivership,      Stellar Ohio Tax-Free Money
default or change in the credit quality of the party  Market Fund
providing the credit enhancement may adversely
affect the quality and marketability of the
underlying security causing the Fund to lose money.
--------------------------------------------------------------------------------
Options Risk--A Fund may use options for hedging      Firstar Strategic Income Fund
purposes only. The hedging strategy may not be        Stellar Strategic Income and
successful if the portfolio manager is unable to      Stellar Funds
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

equity securities tend to shift in and out of favor   Stellar Relative Value Fund
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 may decline  Firstar Science & Technology Fund
in price due to industry specific developments.       Stellar Science & Technology Fund
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--Science    Firstar Science & Technology Fund
and technology related companies face special risks   Stellar Science & Technology Fund
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 performance       Firstar Science & Technology Fund
impact on a Fund with small asset base. The impact    Stellar Science & Technology Fund
of IPOs on a Fund's performance will decrease as a
Fund's asset size increases.
--------------------------------------------------------------------------------
High Yield Bond Risk--High yield bonds (generally     Firstar Global Equity Fund
referred to as junk bonds) are considered             Stellar International Equity Fund
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 performance directly  Firstar Global Equity Fund
relates to the performance of the funds in which it   Stellar International Equity Fund
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 Transaction Risk--   Stellar Treasury Fund
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 Risk--The   Stellar Insured Tax-Free Bond
Fund may invest more than 25% of its assets in        Fund
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 securities   Firstar Balanced Income Fund
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 investments follow     Firstar MidCap Index Fund
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.

                              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 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.

  Shareholders of different Stellar Funds and of different classes of each
such Fund will be affected differently by the Reorganization. Some Firstar
Funds will have different operating expenses and investment policies than
their corresponding Stellar Fund. For more information please see "Comparison
of Stellar Funds and Firstar Funds" below.

  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 applicable 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 applicable 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 applicable 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.

                                      20
<PAGE>

  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 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. An application requesting relief with respect
to Section 17(a) of the 1940 Act has been filed with the SEC and it is
expected that the SEC will issue an order granting such relief prior to the
Reorganization.

  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 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.


                                      21
<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 classes of the corresponding
Stellar Funds before the Reorganization. See "Fee Tables--Table I-C--Total
Expense Information" above and "Comparison of Stellar Funds and Firstar
Funds--Fees and Expenses" below for more information. The Stellar Trustees
also considered, however, that many shareholders of such Funds had purchased
their shares through an investment management, trust, custody, or other agency
relationship with Firstar Bank, N.A. and would be receiving Institutional
Shares of the Corresponding Firstar Fund with lower expenses than what they
had while invested in the relevant Stellar Fund. The Stellar Trustees 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 for the period from the applicable
effective time of the Reorganization for each respective Stellar Fund through
October 31, 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 their respective share classes, 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
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.

(Pro forma Combined Fund = Fund B + Fund C) and (b) the combination of the

  Federal Income Tax Considerations. Each Firstar Fund and each Stellar Fund
intends to qualify as of the applicable 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 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 Generally. 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 generally
in this section and followed by a more detailed fund-by fund analysis below.
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 Generally. 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 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 Generally. 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 Firstar
National Municipal Bond Fund invests at least 80% of its total assets in
municipal securities that pay interest that is exempt from federal income tax.
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 is not
subject to the alternative minimum 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.

                                      32
<PAGE>

  Reorganizing Equity Funds Generally. 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 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 adviser 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.

  Fund-by-Fund Analysis. This Fund-by-Fund analysis provides additional
information concerning 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 section. 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.

                                      33

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 statistical rating organizations ("NRSROs") (or one such rating if
only one NRSRO 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 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, 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.

                                      34
<PAGE>

  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 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.

                                      35
<PAGE>

  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.

  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

                                      36
<PAGE>

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 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.

                                      37

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.

  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 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 400 Index, to keep its assets substantially exposed
to the market (as represented by the 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 400 Index.

  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 adviser and sub-adviser 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

  Sales Loads, Distribution 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, other than
the Stellar Treasury Fund, Stellar Tax-Free 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 below in
"Shareholder Transactions and Services of the Firstar Funds and the
Corresponding Stellar Funds." 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 below in "Shareholder
Transactions and Services of the Firstar Funds and the Corresponding Stellar
Funds."

  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

                                      40

prospectuses to persons other than current shareholders, printing and mailing
sales literature, and compensating underwriters, dealers and sales personnel.

Fund and Stellar Ohio Tax-Free Money Market Fund offer Class C Shares. Class C

  Stellar has adopted a Distribution Plan for Class C Shares pursuant to which
Stellar's distributor is entitled to receive fees at the annual rate of up to
0.25% of the average aggregate net asset value of Class C Shares of the Fund
held during the month. Currently, only the Stellar Treasury Fund pays
distribution fees. Payments to the Distributor are used to finance activities
that promote the sale of the Fund's 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

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 $100,000 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

                                      44
<PAGE>

  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 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 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.

(c)Quantity Discounts

  (i)Stellar Class A Shares

    As the dollar amount of an investor's purchase increases, the 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").

(d)Reinvestment Privilege

  (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 60 days, to reinvest the redemption
  proceeds at the next-determined 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 an investor sells shares of a Firstar Fund or of any fund in the
  Firstar family of funds, the investor may reinvest some or all of the
  proceeds 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 a shareholder is 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).

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

  Unless a shareholder qualifies 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 the Prospectus for such Retail B Shares. 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.

  Stellar Funds

  Shareholders can exchange shares between Stellar Funds within the same
class. Shareholders also may exchange Class C Shares for Class A or Class B
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

  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 Firstar Retail A and Stellar Class A Shares, the applicable
front-end sales charge.

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

  NAV for Stellar's Equity and Bond Funds and Firstar's Equity and Bond Funds
is determined on any day that the New York Stock Exchange (the "Exchange") is
open for business. NAV for Stellar Money Market Funds and Firstar's Money
Market Funds is determined on any day that both the Exchange and the Federal
Reserve Banks' Fedline System is open.

  An Investor's order for the purchase of shares is priced at the next NAV
calculated after the order is received. An investor's order for redemption of
shares is priced at the next NAV calculated after the shares are properly
tendered for redemption.

  Fees and Expenses.

  As discussed further below, certain Stellar shareholders will be reorganized
into share classes with higher total fund operating expenses. More
specifically, 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 and/or expense reimbursements) 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 and/or expense
reimbursements) that are lower after the Reorganization. In addition, with
respect to four out of the eight Stellar Funds in which Stellar Class A
shareholders will be receiving Retail A Shares of the Corresponding Firstar
Fund and with respect to two out of the eight Stellar Funds in which Stellar
Class B 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 and/or expense
reimbursements) 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 and/or expense reimbursements)
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.

  Specifically, Class A shareholders of the Stellar Strategic Income Fund and
Insured Tax-Free Bond Fund who will receive Retail A Shares in the
Reorganization, and Class B shareholders of the Stellar Strategic Income Fund,
U.S. Government Income Fund, Insured Tax-Free Bond Fund, Growth Equity Fund,
Relative Value Fund and Science & Technology Fund who will receive Retail B
Shares in the Reorganization, will have total operating expense ratios (after
fee waivers and/or expense reimbursements) that are higher after the
Reorganization than what they had while invested in the relevant Stellar Fund
prior to the Reorganization. Conversely, Class A shareholders of the Stellar
U.S. Government Income Fund, Relative Value Fund, Stellar Fund and Capital
Appreciation Fund who will receive Retail A Shares in the Reorganization,
Class A shareholders of the Stellar U.S. Government Income Fund, Insured Tax-
Free Bond Fund, Capital Appreciation Fund and International Equity Fund who
will receive Institutional Shares in the Reorganization, Class B shareholders
of the Stellar Capital Appreciation Fund and Stellar Fund who will receive
Retail B Shares in the Reorganization, and Class B shareholders of the Stellar
Strategic Income Fund, U.S. Government Income Fund, Insured Tax-Free Bond Fund
and Capital Appreciation Fund who will receive Institutional Shares in the
Reorganization, will each have total operating expense ratios (after fee
waivers and/or expense reimbursements) that are lower after the Reorganization
than what they had while invested in the relevant Stellar Fund prior to the
Reorganization. Class A shareholders of the Stellar Growth Equity Fund and
Stellar Science & Technology Fund who will receive Retail A Shares in the
Reorganization, will have total operating expense ratios (after fee waivers
and/or expense reimbursements) that are the same after the Reorganization as
what they had while invested in the relevant Stellar Fund prior to the
Reorganization.

  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.

  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

                                      51

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 for the period from the applicable effective time of the
reorganization for each respective Firstar Fund through October 31, 2001.
These fee waivers and expense reimbursements may be terminated at any time
after October 31, 2001 at FIRMCO's discretion.

 + 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 U.S. Treasury Money Market Fund.
 * The Mercantile Treasury Money Market Portfolio is expected to reorganize
   into the Firstar U.S. Treasury Money Market Fund contemporaneously with the
   Reorganization. The reorganization of the 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. The failure of the Mercantile Treasury
   Money Market Portfolio to reorganize into the Firstar U.S. Treasury Money
   Market Fund as expected will not affect the Reorganization of the Stellar
   Treasury Fund into the Firstar U.S. Treasury Money Market Fund and will
   have no material affect on the above expense estimates.
 ++Institutional Shares will not be issued until the Reorganization is
   effective.
(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 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.

    committed to waiving/reimbursing fees as needed to ensure that Total Fund
    Operating Expense ratios will not exceed the pro forma after waiver
    expense ratios for the period from the applicable effective time of the
    Reorganization for each respective Firstar Fund through October 31, 2001.

 + In the Reorganization, holders of Trust Shares and Trust II Shares of the
   Mercantile Tax-Exempt Money Market Portfolio will each receive
   Institutional Shares of the Firstar Tax-Exempt Money Market Fund; and
   holders of Investor A Shares of the Mercantile Tax-Exempt Money Market
   Portfolio, and holders of Class C Shares of the Stellar Tax-Free Money
   Market Fund who purchased their shares through an investment management
   trust, custody or other agency relationship with Firstar Bank, N.A. will

   Fund will receive Retail A Shares of the Firstar Tax-Exempt Money Market
   Fund.
 * The Mercantile Tax-Exempt Money Market Portfolio is expected to reorganize
   into the Firstar Tax-Exempt Money Market Fund contemporaneously with the
   Reorganization. The Reorganization of the Stellar Tax-Free Money Market
   Fund into the Firstar Tax-Exempt Money Market Fund and the reorganization
   of the Mercantile Tax-Exempt Money Market Portfolio into the Firstar Tax-
   Exempt Money Market Fund will occur only if the shareholders of the
   appropriate Funds approve each transaction. The failure of the Mercantile
   Tax-Exempt Money Market Portfolio to reorganize into the Firstar Tax-Exempt
   Money Market Fund as expected will not affect the Reorganization of the
   Stellar Tax-Free Money Market Fund into the Firstar Tax-Exempt Money Market
   Fund and will have no material affect on the above expense estimates.
 ++Institutional Shares will not be issued until the Reorganization is
   effective.

    committed to waiving/reimbursing fees as needed to ensure that Total Fund
    Operating Expense ratios will not exceed the pro forma after waiver
    expense ratios for the period from the applicable effective time of the
    Reorganization for each respective Firstar Fund through October 31, 2001.

borne by the shareholders of the Stellar Strategic Income Fund is as follows:

    Class A Shares--increase 0.09%

    Class B Shares not purchased through an investment management, trust,
  custody, or other agency relationship with Firstar Bank, N.A.--increase
  0.34%

    Class B Shares purchased through an investment management, trust,

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

(6) "Other Expenses" are expected to be less than the amounts shown above

    their fees and/or reimbursing the Funds for certain "Other Expenses."

(7) As a result of fee waivers and/or the expense reimbursements, 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. FIRMCO has
    committed to waiving/reimbursing fees as needed to ensure that Total Fund
    Operating Expense ratios will not exceed the pro forma after waiver
    expense ratios for the period from the applicable effective time of the
    Reorganization for each respective Fund through October 31, 2001. These
    fee waivers and expense reimbursements may be terminated at any time after
    October 31, 2001 at FIRMCO's discretion.

*  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

 + In the Reorganization, holders of Trust Shares of the Mercantile U.S.

   Shares of the Stellar U.S. Government Income 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 U.S. Government Securities Fund. All other holders of Class
   A Shares of the Stellar U.S. Government Income Fund will receive Retail A

   Holders of Institutional Shares of the Mercantile U.S. Government

   Government Securities Fund.
 * The Mercantile U.S. Government Securities Portfolio is expected to
   reorganize into the Firstar U.S. Government Securities Fund
   contemporaneously 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

                                      63
<PAGE>

   only occur if the shareholders of the appropriate Funds approve each
   transaction. The failure of the Mercantile U.S. Government Securities
   Portfolio to reorganize into the Firstar U.S. Government Securities Fund as
   expected will not affect the Reorganization of the Stellar U.S. Government
   Income Fund into the Firstar U.S. Government Securities Fund and will have
   no material affect on the above expense estimates.
(1) The Firstar U.S. Government Securities Fund has not yet commenced
    operations. Upon consummation of the Reorganization, 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:

    Operating Expense ratios will not exceed the pro forma after waiver
    expense ratios for the period from the applicable effective time of the

 + 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

   Fund.
 * The Mercantile U.S. Government Securities Portfolio is expected to
   reorganize into the Firstar U.S. Government Securities Fund
   contemporaneously 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. The failure of the

<PAGE>

   Mercantile U.S. Government Securities Portfolio to reorganize into the
   Firstar U.S. Government Securities Fund as expected will not affect the
   Reorganization of the Stellar U.S. Government Income Fund into the Firstar
   U.S. Government Securities Fund and will have no material affect on the
   above expense estimates.
(1) The Firstar U.S. Government Securities Fund has not yet commenced
    operations. Upon consummation of the Reorganization, 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 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:

(8) As a result of fee waivers and/or the expense reimbursements, 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. FIRMCO has
    committed to waiving/reimbursing fees as needed to ensure that Total Fund
    Operating Expense ratios will not exceed the pro forma after waiver
    expense ratios for the period from the applicable effective time of the
    Reorganization for each respective Firstar Fund through October 31, 2001.
    These fee waivers and expense reimbursements may be terminated at any time
    after October 31, 2001 at FIRMCO's discretion.

     These fee waivers and/or reimbursements are made in order to keep the
     annual fees and expenses of the Funds at a certain level. FIRMCO has
     committed to waiving/reimbursing fees as needed to ensure that Total Fund
     Operating Expense ratios will not exceed the pro forma after waiver
     expense ratios for the period from the applicable effective time of the
     Reorganization for each respective Firstar Fund through October 31, 2001.
     These fee waivers and expense reimbursements may be terminated at any
     time after October 31, 2001 at FIRMCO's discretion.

  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
   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 contemporaneously 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. The failure of the Mercantile
   National Municipal Bond Portfolio to reorganize into the Firstar National
   Municipal Bond Fund as expected will not affect the Reorganization of the
   Stellar Insured Tax-Free Bond Fund into the Firstar National Municipal Bond
   Fund and will have no material affect on the above expense estimates.
(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.
(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:

(8) As a result of fee waivers and/or the expense reimbursements, 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. FIRMCO has
    committed to waiving/reimbursing fees as needed to ensure that Total Fund
    Operating Expense ratios will not exceed the pro forma after waiver
    expense ratios for the period from the applicable effective time of the
    Reorganization for each respective Firstar Fund through October 31, 2001.
    These fee waivers and expense reimbursements may be terminated at any time

    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."

(7) As a result of fee waivers and/or the expense reimbursements, 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. FIRMCO has
    committed to waiving/reimbursing fees as needed to ensure that Total Fund
    Operating Expense ratios will not exceed the pro forma after waiver
    expense ratios for the period from the applicable effective time of the
    Reorganization for each respective Firstar Fund through October 31, 2001.
    These fee waivers and expense reimbursements may be terminated at any time

(6) As a result of fee waivers and/or the expense reimbursements, 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. FIRMCO has
    committed to waiving/reimbursing fees as needed to ensure that Total Fund
    Operating Expense ratios will not exceed the pro forma after waiver
    expense ratios for the period from the applicable effective time of the
    Reorganization for each respective Firstar Fund through October 31, 2001.
    These fee waivers and expense reimbursements may be terminated at any time
    after October 31, 2001 at FIRMCO's discretion.

  Total Fund Operating Expenses (after waivers) would be:

    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.
(3) Management Fees (after waivers) would be:

 * In the Reorganization, holders of Class A 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 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.

(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:

(7) As a result of fee waivers and/or the expense reimbursements, 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. FIRMCO has
    committed to waiving/reimbursing fees as needed to ensure that Total Fund
    Operating Expense ratios will not exceed the pro forma after waiver
    expense ratios for the period from the applicable effective time of the
    Reorganization for each respective Firstar Fund through October 31, 2001.
    These fee waivers and expense reimbursements may be terminated at any time

* 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.

  Performance Comparisons of the Existing Firstar Funds and their
Corresponding Stellar Funds.

  The following section is a comparison of the total return performance of the
Reorganizing Stellar Funds with the total return performance of the Existing
Firstar Funds and is followed by the Management Discussion of Firstar Fund
Performance which was included in the Firstar Annual Report for the fiscal
year ended October 31, 1999.

  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.

                  Management Discussion of 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 its 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 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.

  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 interests 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 "Shareholder Transactions and Services of the Firstar Funds and the
Corresponding Stellar Funds."

  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 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 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 $6,000.

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

  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.

  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.

  (b) The net asset value of each class of Firstar Fund Shares shall be
computed at the Applicable Valuation Time (as hereinafter defined) in the
manner set forth in such Firstar Fund's then current prospectus under the

class of a Stellar Fund shall be computed at the Applicable Valuation Time in
the manner set forth in such Stellar Fund's then current prospectus under the
1933 Act.

  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
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 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.

  5. Valuation Times. Subject to Section 4(b) hereof, the valuation time with
respect to the Existing Firstar Funds and the Reorganizing Stellar Funds shall
be 4:00 p.m., Eastern Time, on November 24, 2000, or such

                                      I-8

earlier or later date and time as may be mutually agreed in writing by an
authorized officer of each of the parties (the "First Valuation Time").
Subject to Section 4(b) hereof, the valuation time with respect to the Shell
Firstar Funds and the Continuing Stellar Funds shall be 4:00 p.m., Eastern
Time, on December 8, 2000, or such earlier or later date and time as may be
mutually agreed in writing by an authorized officer of each of the parties
(the "Second Valuation Time" and, together with the First Valuation Time, each

be no less than one week 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.

  6. Effective Time of the Reorganization.

  (a) Delivery by each Reorganizing Stellar Fund of its respective Assets to
its Corresponding Firstar Fund, delivery by such Corresponding Firstar Fund of
its respective Firstar Fund Shares to such Reorganizing Stellar Fund, and
liquidation of each such Reorganizing Stellar Fund, in each case, pursuant to
Section 2 hereof, shall occur at the opening of business on the next business
day following the First Valuation Time (or on such other date following the
First 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 taken shall be the "Applicable Effective Time of the Reorganization" with
respect to the Existing Firstar Funds and the Reorganizing Stellar Funds. To
the extent any Assets of any Reorganizing Stellar Fund are, for any reason,
not transferred to its Corresponding Firstar Fund at the Applicable Effective
Time of the Reorganization with respect to such Funds, Stellar shall cause
such Assets to be transferred in accordance with this Agreement at the
earliest practicable date thereafter.

  (b) Delivery by each Continuing Stellar Fund of its respective Assets to its
Corresponding Firstar Fund, delivery by each such Corresponding Firstar Fund
of its respective Firstar Fund Shares to such Continuing Stellar Fund, and the
liquidation of each such Continuing Stellar Fund, in each case, pursuant to
Section 2 hereof, shall occur at the opening of business on the next business
day following the Second Valuation Time (or on such other date following the
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 taken shall be the "Applicable Effective Time of the Reorganization" with
respect to the Shell Firstar Funds and the Continuing Stellar Funds. To the
extent any Assets of any Continuing Stellar Fund are, for any reason, not
transferred at the Applicable Effective Time of the Reorganization with
respect to such Funds, Stellar shall cause such Assets to be transferred in
accordance with this Agreement at the earliest practicable date thereafter.

  7. Termination of Stellar. Promptly following the Applicable Effective Time
of the Reorganization with respect to the Shell Firstar Funds and their
Corresponding Stellar Funds, Stellar shall file an application pursuant to
Section 8(f) of the 1940 Act for an order declaring that Stellar has ceased to
be an investment company; provided that until such order is granted, Stellar

state and federal securities laws (including, in the case of each of the
foregoing, the rules and regulations thereunder). Stellar shall, promptly
after the Applicable Effective Time of the Reorganization with respect to the
Shell Firstar Funds and their Corresponding Stellar Funds, file any final
regulatory reports, including, but not limited to, any Form N-SAR and Rule
24f-2 Notice, with respect to such Stellar Fund(s). All reporting and other
obligations of Stellar shall remain the exclusive responsibility of Stellar up
to and including the date on which such Stellar Fund is deregistered and
terminated. In addition, promptly following the Applicable Effective Time of
the Reorganization with respect to the Shell Firstar Funds and their
Corresponding Stellar Funds, Stellar shall be terminated pursuant to its
Declaration of Trust and shall take all other steps necessary and proper to
effect its complete termination. Without limiting the generality of the
foregoing, (a) the affairs of Stellar shall be immediately wound up, its

  14. Stellar Conditions. The obligations of Stellar (and of each respective
Stellar Fund) hereunder shall be subject to the following conditions
precedent:

    (a) This Agreement and the transactions contemplated by this Agreement
  shall have been approved by the Board of Directors of Firstar (including

  shareholders of each of the Stellar Funds, in each case, in the manner
  required by law.

    (b) The Articles of Amendment shall have been approved by the
  shareholders of Firstar and filed with the office of the Department of
  Financial Institutions of the State of Wisconsin.

  shall be true and correct in all material respects on the date hereof, at
  the Applicable Valuation Time and at the Applicable Effective Time of the
  Reorganization, in each case, as if made at and as of such time. As of the
  Applicable Valuation Time and at the Applicable Effective Time of the
  Reorganization, there shall have been no material adverse change in the
  financial position of any Firstar Fund or of Firstar since the date of the
  most recent financial statements referred to in Section 9(h) other than
  those changes (including, without limitation, changes due to net
  redemptions) incurred in the ordinary course of business as an investment
  company since the date of the most recent financial statements referred to
  in Section 9(h). At the Applicable Effective Time of the Reorganization,
  Stellar shall have received a certificate from the President or Vice
  President of Firstar, dated as of such date, certifying on behalf of
  Firstar that as of such date each of the conditions set forth in this
  clause (c) have been met.

    (d) Stellar shall have received opinions of Drinker Biddle & Reath LLP,
  counsel to Firstar, addressed to Stellar in form and substance reasonably
  satisfactory to Stellar and dated the Applicable Effective Time of the
  Reorganization, to the effect that as of the date of such opinion, and
  subject to qualifications and conditions reasonably acceptable to Stellar:
  (i) Firstar is a corporation duly organized, validly existing and in good
  standing under the laws of the State of Wisconsin; (ii) the shares of each
  Existing or Shell Firstar Fund, as appropriate, to be delivered to its
  Corresponding Stellar Fund are duly authorized and upon delivery will be
  validly issued, fully paid and non-assessable by such Firstar Fund, and to
  such counsel's knowledge, no shareholder of any Firstar Fund has any
  statutory preemptive right to subscription or purchase in respect thereof;
  (iii) this Agreement has been duly and validly authorized, executed and
  delivered by Firstar and represents the legal, valid and binding obligation
  of Firstar, enforceable against Firstar in accordance with the terms
  hereof, subject to the effect of bankruptcy, insolvency, reorganization,
  arrangement, moratorium, fraudulent transfer or conveyance and similar laws
  relating to or affecting creditors' rights and remedies generally and court
  decisions with respect thereto, and such counsel shall express no opinion
  with respect to the application of equitable principles in any proceeding,
  whether at law or in equity, as to the enforceability of any provision of
  the Agreement relating to remedies after default, as to the availability of
  any specific or equitable relief of any kind, or with respect to the
  provisions of this Agreement intended to limit liability for particular
  matters to a particular Firstar Fund and its Assets, including but not
  limited to Section 33 of this Agreement; (iv) the execution and delivery of
  this Agreement did not, and the consummation of the transactions
  contemplated by this Agreement will not, violate the Articles of
  Incorporation or Bylaws of Firstar, or any material agreement known to such
  counsel to which Firstar is a party or by which Firstar may be bound; and
  (v) to such counsel's knowledge, no consent, approval, authorization or
  order of any court, governmental authority or agency is required for the
  consummation by Firstar of the transactions contemplated by this Agreement,
  except such as have been obtained under the 1933 Act, the 1934 Act, the
  1940 Act, and Wisconsin corporate and securities laws (including, in the
  case of each of the foregoing, the rules and regulations thereunder). Such
  opinions may rely on opinions of Foley & Lardner to the extent set forth in
  each such opinion.

    (e) The N-14 Registration Statement shall have become effective under the
  1933 Act and no stop order suspending such effectiveness shall have been
  instituted, or, to the knowledge of Stellar, contemplated by the SEC, and
  the parties shall have received all permits, licenses and other
  authorizations necessary under applicable state securities laws to
  consummate the transactions contemplated by this Agreement, and all such
  permits and other authorizations shall be in full force and effect at such
  time.

satisfactory to them, and dated as of the Applicable Effective Time of the
Reorganization, substantially to the effect that on the basis of facts,
representations, and assumptions set forth in such opinions, and subject to
qualifications and exceptions reasonably acceptable to the parties:

    (a) The Reorganization will consist of twelve "reorganizations" within
  the meaning of Section 368(a) of the Code, and each Stellar Fund and the
  Corresponding Firstar Fund will each be a "party to a reorganization"
  within the meaning of Section 368(b) of the Code with respect to such
  Reorganization;

    (b) In accordance with Section 361(a), 361(c)(1) and 357(a) of the Code,
  no gain or loss will be recognized by any Stellar Fund upon the transfer of
  substantially all of its Assets and substantially all of its Liabilities to
  the Corresponding Firstar Fund in exchange for the Firstar Fund Shares of
  the Corresponding Firstar Fund;

    (c) In accordance with Section 1032(a) of the Code, no gain or loss will
  be recognized by each Firstar Fund upon the receipt of substantially all of
  the Assets and assumption of substantially all of the Liabilities of the
  Corresponding Stellar Fund in exchange for the Firstar Fund Shares;

    (d) In accordance with Section 362(b) of the Code, 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 the Stellar Fund immediately prior to the Reorganization;

    (e) In accordance with Section 1223(2) of the Code, the holding period of
  each Stellar Fund's Assets in the hands of the Corresponding Firstar Fund
  will include the period for which such Assets have been held by the Stellar
  Fund;

    (f) In accordance with Section 361(a), 361(c)(1) and 357(a) of the Code,
  no gain or loss will be recognized by any Stellar Fund on the distribution
  to its shareholders of the Firstar Fund Shares to be received by the
  Stellar Fund in the Reorganization;

    (g) In accordance with Section 354(a)(1) of the Code, no gain or loss
  will be recognized by the shareholders of any Stellar Fund upon their
  receipt of the Corresponding Firstar Fund Shares in exchange for such
  shareholders' shares of the Stellar Fund;

    (h) In accordance with Section 358(a)(1) of the Code, the basis of the
  Firstar Fund Shares received by the shareholders of each Corresponding
  Stellar Fund will be the same as the basis of the Stellar Fund shares
  surrendered by such shareholders pursuant to the Reorganization;

    (i) In accordance with Section 1223(1) of the Code, the holding period
  for the Firstar Fund Shares received by each Stellar Fund shareholder will
  include the period during which such shareholder held the Stellar Fund
  shares surrendered 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

    (j) Each Firstar Fund will succeed to and take into account the tax
  attributes described in Section 381(c) of the Code of the Corresponding
  Stellar Fund as of the Applicable Effective Time of the Reorganization,
  subject to the conditions and limitations specified in the Code.

                                     I-17

  In rendering such opinions described in this paragraph, Drinker Biddle &
Reath LLP may require and, to the extent it deems necessary and appropriate,
may rely upon representations made in certificates of Firstar Funds and
Stellar Funds, their affiliates, and principal shareholders.

  16. Tax Documents. Stellar shall deliver to Firstar at the Applicable
Effective Time of the Reorganization, confirmations and/or other evidence
satisfactory to Firstar as to the adjusted tax basis of the Assets of each
Stellar Fund delivered to a Firstar Fund in accordance with the terms of this
Agreement.

  17. Further Assurances. Subject to the terms and conditions herein provided,
each of the parties hereto shall use its best efforts to execute and deliver,
or cause to be executed and delivered, such additional documents and
instruments and to do, or cause to be done, all things necessary, proper or
advisable under the provisions of this Agreement and under applicable law to
consummate and make effective the transactions contemplated by this Agreement,
including, without limitation, delivering and/or causing to be delivered to
the other party hereto each of the items required under this Agreement as a
condition to such other party's obligations hereunder. In addition, Stellar
shall deliver or cause to be delivered to Firstar, each account, book, record
and other document of Stellar required to be maintained by Stellar pursuant to
Section 31(a) of the 1940 Act and Rules 31a-1 to 31a-3 thereunder (regardless
of whose possession they are in).

  18. Termination of Representations and Warranties. The representations and
warranties of the parties set forth in this Agreement shall terminate upon the
consummation of the transactions contemplated herein; provided, however, that
nothing contained in this Section 18 shall be construed (a) to terminate the
obligations of each Firstar Fund to discharge the Liabilities of the
Corresponding Stellar Fund assumed pursuant to Section 2(b) hereof, or (b) to
terminate the obligations of Firstar to provide liability coverage for the
Trustees and officers of Stellar and to indemnify the Trustees of Stellar, in
each case, pursuant to the covenants set forth in Section 9(n) hereof.

  19. Termination of Agreement. This Agreement may be terminated by a party at
any time at or prior to the Applicable Effective Time of the Reorganization by
a vote of a majority of such party's Board of Directors or Trustees, as
applicable, as provided below:

    (a) By Firstar if the conditions set forth in Section 13 are not
  satisfied as specified in said Section;

    (b) By Stellar if the conditions set forth in Section 14 are not
  satisfied as specified in said Section; or

    (c) By mutual consent of both parties.

  If a party terminates this Agreement because one or more of its conditions
have not been fulfilled, or if this Agreement is terminated by mutual consent,
this Agreement will become null and void insofar as it is so terminated
without any liability of any party to the other parties except as otherwise
provided herein.

  20. Amendment and Waiver. At any time prior to or (to the fullest extent
permitted by applicable law) after approval of this Agreement by the
shareholders of Stellar in accordance with Section 10 hereof, (a) the parties
hereto may, by written agreement authorized by their respective Boards of
Directors or Trustees, as the case may be, and with or without the approval of
their shareholders, amend, modify or terminate any of the provisions of this
Agreement, and (b) any party may waive any breach by any other party or any
failure by any other party to satisfy any of the conditions to the obligations
of the waiving party (such waiver to be in writing and authorized by an
authorized officer of the waiving party) with or without the approval of such
party's shareholders.

  21. Governing Law. This Agreement and the transactions contemplated hereby
shall be governed, construed and enforced in accordance with the internal laws
of the State of Wisconsin, without giving effect to the conflicts of law
principles of such state.

  22. Successors and Assigns. This Agreement shall be binding upon the
respective successors and permitted assigns of the parties hereto. This
Agreement and the rights, obligations and liabilities hereunder may not be
assigned by any party without the prior written consent of the other party.

hereof and (b) the successors and permitted assigns of the parties.

Stellar entered into in the name or on behalf thereof by any of the trustees,
representatives or agents are made not individually, but in such capacities,
and are not binding upon any of the trustees, shareholders or representatives
of Stellar personally, but bind only the trust property, and all persons
dealing with any series of shares of Stellar must look solely to the trust
property belonging to such series for the enforcement of any claims against
Stellar.

  Both parties specifically acknowledge and agree that any liability of
Stellar under this Agreement with respect to a Stellar Fund, or in connection
with the transactions contemplated herein with respect to a particular Stellar
Fund, shall be discharged only out of the assets of the particular Stellar

                              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.

*   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.

     At the same time that the Mercantile Funds are reorganized into the Firstar
Funds, it is expected that the investment portfolios of the 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 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. Consummation of the Stellar and Select reorganizations is
subject to numerous conditions described in the relevant reorganization
agreement, including approval by shareholders of Mercantile and Select. If the
Reorganization Agreement is approved by Mercantile shareholders at the Special
Meeting, it is
<PAGE>

expected that the Reorganization will be completed whether or not the Stellar
reorganization and Select reorganization are completed.

     Pro forma financial information has been prepared for the reorganizations
of the (1) Mercantile Treasury Money Market Portfolio and Stellar Treasury Fund
into the Firstar U.S. Treasury Money Market Fund; (2) Mercantile Money Market
Portfolio into the Firstar Money Market Fund; (3) Mercantile Tax-Exempt Money
Market Portfolio and Stellar Tax-Free Money Market Fund into the Firstar Tax-
Exempt Money Market Fund; (4) Mercantile U.S. Government Securities Portfolio
and Stellar U.S. Government Income Fund into the Firstar U.S. Government
Securities Fund; (5) Mercantile Intermediate Corporate Bond Portfolio into the
Firstar Intermediate Bond Market Fund; (6) Mercantile Bond Index Portfolio and
Mercantile Government & Corporate Bond Portfolio into the Firstar Aggregate Bond
Fund; (7) Mercantile Short-Intermediate Municipal Portfolio into the Firstar
Tax-Exempt Intermediate Bond Fund; (8) Mercantile National Municipal Bond
Portfolio and Stellar Insured Tax-Free Bond Fund into the Firstar National
Municipal Bond Fund; (9) Mercantile Balanced Portfolio into the Firstar Balanced
Growth Fund; (10) Mercantile Equity Index Portfolio into the Firstar Equity
Index Fund; (11) Mercantile Growth & Income Equity Portfolio into the Firstar
Growth & Income Fund; (12) Mercantile Growth Equity Portfolio into the Firstar
Growth Fund; (13) Mercantile Small Cap Equity Portfolio into the Firstar
Emerging Growth Fund and (14) Mercantile International Equity Portfolio into the
Firstar Core International Equity Fund. Pro forma information has been provided
for the reorganizations of the (1) Mercantile Conning Money Market Portfolio
into the Firstar Conning Money Market Fund, (2) Mercantile Missouri Tax-Exempt
Bond Portfolio into the Firstar Missouri Tax-Exempt Bond Fund, (3) Mercantile
Equity Income Portfolio into the Firstar Equity Income Fund, and (4) Mercantile
Small Cap Equity Index Portfolio into the Firstar Small Cap Index Fund because
in each of the cases the Mercantile Fund is being reorganized into a newly
organized Firstar Fund that is being created to continue the operations of such
Stellar Fund and no portfolio offered by Stellar or Select is being
simultaneously reorganized into such Firstar Fund.

     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 Fund shareholders or Firstar Stellar Fund shareholders will approve
the reorganization of their 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 Funds incorporated herein by reference in this Statement of Additional
Information. Each combination of the above Mercantile Funds (and Firstar Stellar
Funds, as applicable) 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.

information has not been provided for (1) the reorganization of the Stellar Ohio
Tax-Free Money Market Fund into the Firstar Ohio Tax-Exempt Money Market Fund,
(2) the reorganization of the Stellar Strategic Income Fund into the Firstar
Strategic Income Fund, (3) the reorganization of the Stellar Growth Equity Fund
into the Firstar Large Cap Growth Fund, (4) the reorganization of the Stellar
Relative Value Fund into the Firstar Relative Value Fund, (5) the reorganization
of the Stellar Science & Technology Fund into the Firstar Science & Technology
Fund and (6) the reorganization of the Stellar International Equity Fund into
the Firstar Global Equity Fund, because in each of these cases, the Stellar Fund
is being reorganized into a newly organized Firstar Fund that is being created
to continue the operations of such Stellar Fund and no portfolio offered by
Mercantile or Select is being simultaneously reorganized into such Firstar Fund.

      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,

                                      -2-

Stellar Treasury Fund and Firstar U.S. Treasury Money Market Fund and the
combination of the Mercantile Tax-Exempt Money Market Portfolio, Stellar Tax-
Free Money Market Fund and Firstar Tax-Exempt Money Market Fund because it is
possible that only the Mercantile Fund shareholders or Stellar Fund shareholders
will approve the reorganization of their 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
Firstar Funds incorporated herein by reference in this Statement of Additional
Information. Each combination of the above Stellar Funds (and Mercantile Mutual
Funds, Inc., as applicable) and Firstar Funds will be accounted for as a tax-
free reorganization.

     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

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).

5.   Pro Forma Adjustments and Pro Forma Combined Columns
     ----------------------------------------------------

     The pro forma adjustments and pro forma combined columns of the statements
     of operations reflect the adjustments necessary to show expenses and
     waivers at the rates which would have been in effect if the Firstar Funds,
     Mercantile Funds and Firstar Stellar Funds, as appropriate, were included
     in the Surviving Funds for the year ended April 30, 2000. These rates are
     included in the N-14 Registration statement.

     The pro forma statements of assets and liabilities and schedules of
     investments give effect to the proposed combination of such assets as if
     the reorganization had occurred at April 30, 2000. The Surviving Funds will
     offer the following classes:

           Surviving Funds                       Classes of Shares

     More information on the classes of shares offered can be found in the N-14
     Proxy statement.


6.   Portfolio Valuation, Securities Transactions and Related Income
     ---------------------------------------------------------------

     Securities of the Money Market Funds are valued utilizing the amortized
     cost method permitted in accordance with Rule 2a-7 under the 1940 Act.
     Under the amortized cost method, discount or premium is amortized on a
     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.

                                      10

<PAGE>

     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.

7.   Capital Shares
     --------------

     The pro forma net asset values per share assume the issuance of shares of
     the Firstar Funds, after any necessary stock splits, which would have
     occurred at April 30, 2000 in connection with the proposed reorganization.
     The pro forma number of shares outstanding consists of the following:
