                       [FIRST STERLING BANCORP, INC.]

   
                              November 22, 1995

Dear Fellow Shareholder:

   The Board of Directors cordially invites you to attend a Special Meeting
of Shareholders of First Sterling Bancorp, Inc. ("First Sterling") to be held
at 10:00 a.m. Central Time, on Friday, December 22, 1995, at the offices of
First Sterling, 300 First Avenue, Rock Falls, Illinois (the "Special Meeting").
At the Special Meeting, you will be asked to consider and vote upon a
proposal to approve the Agreement and Plan of Merger dated July 24, 1995 (the
"Merger Agreement"), pursuant to which First Sterling will be merged with and
into a wholly owned subsidiary of Mercantile Bancorporation Inc. ("MBI").
    

   I have enclosed the following items relating to the Special Meeting and
the merger:

   1. Proxy Statement/Prospectus;

   2. Proxy card; and

   3. A pre-addressed return envelope to First Sterling for the proxy
card.

The Proxy Statement/Prospectus and related proxy materials set forth, or
incorporate by reference, financial data and other important information
relating to First Sterling and MBI and describe the terms and conditions of
the proposed merger.  The Board of Directors requests that you carefully
review these materials before completing the enclosed proxy card or attending
the Special Meeting.

   THE BOARD OF DIRECTORS OF FIRST STERLING CAREFULLY CONSIDERED AND APPROVED
THE TERMS OF THE MERGER AGREEMENT AS BEING IN THE BEST INTEREST OF FIRST
STERLING AND ITS SHAREHOLDERS.  THE FIRST STERLING BOARD UNANIMOUSLY
RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE PROPOSAL TO APPROVE THE MERGER
                                  ---
AGREEMENT.

   APPROVAL OF THE MERGER AGREEMENT BY THE FIRST STERLING SHAREHOLDERS IS A
CONDITION TO THE CONSUMMATION OF THE MERGER.  Accordingly, it is important
that your shares be represented at the Special Meeting, whether or not you
plan to attend the Special Meeting in person.  Please complete, date and sign
the enclosed proxy card and return it to First Sterling in the enclosed
pre-addressed envelope, which requires no postage if mailed within the United
States.  If you later decide to attend the Special Meeting and vote in
person, or if you wish to revoke your proxy for any reason prior to the vote
at the Special Meeting, you may do so and your proxy will have no further
effect.  You may revoke your proxy by delivering to the Secretary of First
Sterling a written notice of revocation or another proxy relating to the same
shares bearing a later date than the proxy being revoked or by attending the
Special Meeting and voting in person.  Attendance at the Special Meeting will
not in itself constitute a revocation of an earlier dated proxy.

   If you need assistance in completing your proxy card or if you have any
questions about the Proxy Statement/Prospectus, please feel free to contact
me at (815) 626-0045.

   
                                    Sincerely,


                                    /s/ William J. Hank
                                    William J. Hank
                                    President

               NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
                              To Be Held
   
                         December 22, 1995

          TO THE SHAREHOLDERS OF FIRST STERLING BANCORP, INC.:

   Notice is hereby given that a special meeting (the "Special Meeting") of
Shareholders of FIRST STERLING BANCORP, INC., an Illinois corporation ("First
Sterling"), will be held at the offices of First Sterling, 300 First Avenue,
Rock Falls, Illinois on December 22, 1995, at 10:00 a.m. Central Time, for the
following purposes:
    

   (1)   To consider and vote upon a proposal to adopt and approve the
Agreement and Plan of Merger dated July 24, 1995, by and among Mercantile
Bancorporation Inc. ("MBI"), Mercantile Bancorporation Incorporated of
Illinois, a wholly owned subsidiary of MBI ("Merger Sub") and First Sterling
(the "Merger Agreement"), pursuant to which First Sterling will be merged
(the "Merger") with and into Merger Sub, in a transaction which would result
in the business and operations of First Sterling being continued through such
wholly owned subsidiary, and whereby, upon the consummation of the Merger,
each share of First Sterling common stock will be converted into the right to
receive 0.1415 of a share of MBI common stock (together with the associated
share purchase right), as set forth in detail in the attached Proxy
Statement/Prospectus.

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

   
   The record date for determining the shareholders entitled to receive
notice of, and to vote at, the Special Meeting or any adjournments or
postponements thereof has been fixed as of the close of business on November
17, 1995.  On the record date, First Sterling had 3,685,061 shares of Common
Stock issued, outstanding and entitled to vote.  Such shares were held by
approximately 37 holders.  Each share will be entitled one vote on each
matter submitted to a vote at the Special Meeting.
    

   THE AFFIRMATIVE VOTE OF THE HOLDERS OF AT LEAST TWO-THIRDS OF THE
OUTSTANDING SHARES OF FIRST STERLING COMMON STOCK IS REQUIRED FOR APPROVAL OF
THE MERGER AGREEMENT.  YOUR VOTE IS IMPORTANT REGARDLESS OF THE NUMBER OF
SHARES YOU OWN.

   WHETHER OR NOT YOU EXPECT TO ATTEND THE SPECIAL MEETING, PLEASE COMPLETE,
DATE AND SIGN THE ENCLOSED PROXY CARD AND RETURN IT IN THE ACCOMPANYING
ENVELOPE.  THE PROXY MAY BE REVOKED AT ANY TIME PRIOR TO THE VOTE AT THE
SPECIAL MEETING BY FOLLOWING THE PROCEDURES SET FORTH IN THE ACCOMPANYING
PROXY STATEMENT/PROSPECTUS.  FAILURE TO RETURN THE ENCLOSED PROXY CARD OR TO
VOTE AT THE MEETING WILL HAVE THE SAME EFFECT AS A VOTE AGAINST THE MERGER.

   PLEASE DO NOT SEND IN ANY STOCK CERTIFICATES AT THIS TIME.   If the Merger
Agreement is approved, you will be sent instructions regarding the mechanics
of exchanging your existing First Sterling Common Stock certificates for new
certificates representing shares of MBI.

   
                                         BY ORDER OF THE BOARD OF DIRECTORS

                                         /s/ David L. Kingland

                           PROXY STATEMENT
                    SPECIAL MEETING OF SHAREHOLDERS
   
                   TO BE HELD ON DECEMBER 22, 1995

   This Prospectus of Mercantile Bancorporation Inc. ("MBI") relates to up to
521,424 shares of Common Stock, $5.00 par value, and attached Preferred Share
Purchase Rights (the "Rights"), of MBI (the Common Stock and Rights are
collectively referred to herein as the "MBI Common Stock"), to be issued to
the shareholders of First Sterling Bancorp, Inc., an Illinois corporation
("First Sterling"), upon consummation of the proposed merger (the "Merger")
of First Sterling with and into Mercantile Bancorporation Incorporated of
Illinois, a Missouri corporation ("Merger Sub"), which is a wholly owned
subsidiary of MBI.  Upon receipt of the requisite shareholder and regulatory
approvals, and the satisfaction or waiver of certain conditions precedent,
the Merger will be consummated pursuant to the terms of the Agreement and
Plan of Merger dated July 24, 1995 (the "Merger Agreement"), by and among
MBI, Merger Sub and First Sterling.  This Prospectus also serves as the Proxy
Statement of First Sterling for use in connection with the Special Meeting of
Shareholders of First Sterling (the "Special Meeting"), which will be held on
December 22, 1995, at the time and place and for the purposes stated in the
Notice of Special Meeting of Shareholders accompanying this Proxy

   Pursuant to the Merger, MBI will issue up to an aggregate of 521,424

Common Stock"), will be converted into the right to receive 0.1415 of a share
of MBI Common Stock.  The fair market value of MBI Common Stock to be
received pursuant to the Merger may fluctuate and at the consummation of the
Merger may be more or less than the current fair market value of such shares.
See "TERMS OF THE PROPOSED MERGER - General Description of the Merger."  No
fractional shares of MBI Common Stock will be issued in the Merger, but cash
will be paid in lieu of such fractional shares.  See "TERMS OF THE PROPOSED
MERGER - Fractional Shares."

   The transaction is intended to qualify as a reorganization under the
Internal Revenue Code of 1986, as amended (the "Code").  The Merger generally
is intended to achieve certain tax-deferral benefits for federal income tax
purposes for First Sterling shareholders.  See "SUMMARY INFORMATION - Federal
Income Tax Consequences in General" and "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER."

Common Stock as reported on the NYSE Composite Tape was $44.50.

about November 22, 1995.

EXCHANGE COMMISSION (THE "COMMISSION") OR ANY STATE SECURITIES COMMISSION NOR

                            SUMMARY INFORMATION
                            -------------------

      The following is a summary of the important terms of the proposed
Merger and related information discussed elsewhere in this Proxy Statement/
Prospectus but does not purport to be complete and is qualified in its
entirety by reference to the more detailed information which appears
elsewhere in this Proxy Statement/Prospectus and the documents incorporated
by reference herein.  Shareholders of First Sterling are urged to read this
Proxy Statement/Prospectus in its entirety.  All MBI per share data reflect a
three-for-two stock split distributed in the form of a dividend on April 11,
1994.

BUSINESS OF MBI

      MBI, a Missouri corporation, was organized in 1970 and is a registered
bank holding company under the federal Bank Holding Company Act of 1956, as
amended (the "BHCA").  MBI is also registered as a savings and loan holding
company under the Home Owners' Loan Act of 1933, as amended (the "HOLA").  At
September 30, 1995, MBI owned, directly or indirectly, all of the capital
stock (except for a small minority interest in one bank) of Mercantile Bank of
St. Louis National Association ("Mercantile Bank"), 51 other commercial banks
and one federally chartered thrift which operate from 322 banking offices and
316 Fingertip Banking automated teller machines, including 37 off-premises
machines, located throughout Missouri, southern Illinois, eastern Kansas,
northern Arkansas and northern Iowa. MBI's services concentrate in three major
lines of business-consumer, corporate and trust services.   MBI also operates
non-banking subsidiaries which provide related financial services, including
investment management, brokerage services and asset-based lending.  As of
September 30, 1995, MBI had 55,333,878 shares of its Common Stock outstanding.
As of September 30, 1995, MBI reported, on a consolidated basis, total assets
of $16.0 billion, total deposits of $11.8 billion, total loans of $10.6
billion and shareholders' equity of $1.4 billion.

      On January 3, 1995, MBI completed the acquisitions of (i) UNSL
Financial Corp. ("UNSL"), a Delaware corporation and a savings and loan
holding company under the HOLA, located in Lebanon, Missouri, and (ii) Wedge
Bank ("Wedge"), an Illinois state-chartered bank located in Alton, Illinois.
These acquisitions were accounted for under the pooling-of-interests method
of accounting.  As of January 3, 1995, UNSL and Wedge reported total assets
of $508 million and $196 million, respectively.

      On May 1, 1995, MBI completed the acquisitions of (i) Central Mortgage
Bancshares, Inc. ("CMB"), a Missouri corporation and registered bank holding
company under the BHCA, located in Kansas City, Missouri, and (ii)
TCBankshares, Inc. ("TCB"), an Arkansas corporation and a registered bank
holding company under the BHCA, located in North Little Rock, Arkansas.
These acquisitions were accounted for under the pooling-of-interests method
of accounting.  As of May 1, 1995, CMB and TCB reported total assets of $655
million and $1.4 billion, respectively.

      In connection with the acquisitions of UNSL, CMB and TCB, MBI has
restated its consolidated financial statements as of and for the years ended
December 31, 1994, 1993 and 1992.  MBI has filed supplemental financial
statements as of and for the years ended December 31, 1994, 1993 and 1992 in
a Current Report on Form 8-K, dated May 31, 1995, which has been incorporated
by reference into this Proxy Statement/Prospectus.  Due to the immateriality
of the financial condition and results of operation of Wedge to that of MBI,
the supplemental consolidated financial statements of MBI do not reflect the
Wedge transaction.

which was organized in 1986.  Merger Sub is a registered bank holding company

BUSINESS OF FIRST STERLING

      First Sterling, an Illinois corporation formed in November 1982,
commenced operations in March 1983 as a registered bank holding company under

                                    - 8 -
<PAGE> 11

been operating since 1934 and which currently operates from its main office

outstanding.  As of September 30, 1995, First Sterling reported, on a
consolidated basis, total assets of $170.0 million, total deposits of $132.5

million.  See "INFORMATION REGARDING FIRST STERLING."

      First Sterling's principal executive offices are located at 305 4th
Avenue, Sterling, Illinois and its telephone number is (815) 626-0045.

THE PROPOSED MERGER

      Subject to the satisfaction of the terms and conditions set forth in
the Merger Agreement described below, First Sterling will be merged with and
into Merger Sub.  Upon consummation of the Merger, First Sterling's corporate
existence will terminate and Merger Sub will continue as the surviving
entity.  Simultaneously with the effectiveness of the Merger, each share of
First Sterling Common Stock will be converted into the right to receive
0.1415 of a share of MBI Common Stock.  Such consideration is subject to
certain anti-dilution protections but is not adjustable based upon the
operating results, financial condition or other factors affecting either MBI
or First Sterling prior to the consummation of the Merger.  The fair market
value of MBI Common Stock to be received pursuant to the Merger may fluctuate
and at the consummation of the Merger may be more or less than the current
fair market value of such shares.

      KeyCorp Shareholder Services, Inc., the transfer agent for MBI Common
Stock, has been selected as the Exchange Agent (the "Exchange Agent") for
purposes of effecting the conversion of First Sterling Common Stock into MBI
Common Stock upon consummation of the Merger.  As soon as practicable after
consummation of the Merger, a letter of transmittal (including instructions
setting forth the procedures for exchanging certificates representing shares
of First Sterling Common Stock for the MBI Common Stock payable to each
holder thereof pursuant to the Merger Agreement) will be sent to each record
holder as of the Effective Time.  Upon surrender to the Exchange Agent of
such certificate(s), together with a duly completed and executed letter of
transmittal, such holder will receive the shares of MBI Common Stock to which
such holder is entitled under the Merger Agreement.  See "TERMS OF THE
PROPOSED MERGER - Surrender of First Sterling Stock Certificates and Receipt
of MBI Common Stock."

      The Merger Agreement provides that the consummation of the Merger is
subject to certain terms and conditions, including the approval of the Merger
Agreement by the affirmative vote of the holders of at least two-thirds of
the outstanding shares of First Sterling Common Stock and receipt of the
requisite regulatory approval and an opinion of counsel for MBI regarding
certain federal income tax aspects of the transaction.  For a discussion of
each of the conditions to the Merger, see "TERMS OF THE PROPOSED MERGER -
Conditions of the Merger."  The Merger will be consummated and become
effective on the date and at the time (the "Effective Time") that the
certificate of merger is issued by the Missouri Secretary of State.

      Unless the parties otherwise agree, the date of the closing of the
Merger (the "Closing Date") shall occur on such date as MBI shall notify
First Sterling in writing, which date shall be the last to occur of (i)
January 2, 1996 or (ii) the first business day of the first full calendar
month commencing at least five days after all conditions to closing as set
forth in the Merger Agreement are satisfied.  The Merger Agreement may be
terminated at any time prior to the Closing Date by the mutual consent of the


                                    - 9 -
<PAGE> 12

parties or, unilaterally, by either party upon the occurrence of certain
events or if the Merger is not consummated by April 30, 1996.  See "TERMS OF
THE PROPOSED MERGER - Conditions of the Merger" and  "- Termination of the
Merger Agreement."

OTHER AGREEMENTS

   
      Concurrent with the execution of the Merger Agreement, MBI and certain
shareholders, including each of the directors of First Sterling, executed
separate Voting Agreements (the "Voting Agreements") by which each such
shareholder agreed that he or she will vote all of the shares of First
Sterling Common Stock then owned or subsequently acquired in favor of the
approval of the Merger Agreement at the Special Meeting.  In addition, until
the earliest to occur of the Effective Time, the termination of the Voting
Agreement or the termination of the Merger Agreement, each such shareholder
further agreed he or she will not vote any such shares in favor of the
approval of any other competing acquisition proposal involving First Sterling
and a third party.  Each such shareholder also agreed that he or she will not
transfer shares of First Sterling Common Stock unless, prior to such
transfer, the transferee executes an agreement in substantially the same form
as the Voting Agreement.  As of the Record Date (as defined below), the
shareholders of First Sterling who signed Voting Agreements owned
beneficially an aggregate of 2,182,458 shares of First Sterling Common
Stock, or approximately 59.22% of the issued and outstanding shares.
    

INTERESTS OF CERTAIN PERSONS IN THE MERGER

      From and after the Effective Time for a period of not less than five
years, MBI will provide for the indemnification of employees, agents,
directors or officers of First Sterling or any of First Sterling's
subsidiaries, in an amount and of a type not less than that provided by First
Sterling's Articles of Incorporation or bylaws in the form in effect as
of July 24, 1995 or arising by operation of law or arising by virtue of
any contract, resolution or other agreement or document existing as of July
24, 1995.  Further, MBI will assume all duties and obligations of
indemnification of First Sterling or any of First Sterling's subsidiaries
existing as of the Effective Time with respect to any act or omission of any
of their respective employees, agents, directors or officers occurring prior
to the Effective Time; provided, however, that to the extent that First
Sterling's directors' and officers' liability insurance would provide
coverage for any such act or omission, First Sterling agrees to give proper
notice to the insurance carrier and to MBI of a potential claim thereunder so
as to preserve the rights to such insurance coverage.  See "TERMS OF THE
PROPOSED MERGER - Interests of Certain Persons in the Merger."

Common Stock, or approximately 45.03% of the shares entitled to vote at the
Special Meeting. All of First Sterling's directors and executive officers
have indicated their intention to vote their shares for the approval of the
Merger Agreement.  Additionally, each of the directors and certain other
shareholders of First Sterling, pursuant to the terms of his or her
respective Voting Agreement, has committed to vote his or her shares of First

      THE BOARD OF DIRECTORS OF FIRST STERLING CAREFULLY CONSIDERED AND
UNANIMOUSLY APPROVED THE TERMS OF THE MERGER AS BEING IN THE BEST INTEREST OF
FIRST STERLING AND ITS SHAREHOLDERS.  THE FIRST STERLING BOARD UNANIMOUSLY
RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE PROPOSAL TO APPROVE THE MERGER
                                  ---
AGREEMENT.

REASONS FOR THE MERGER

      FIRST STERLING.  The Board of Directors of First Sterling believes
that the Merger is in the best interests of First Sterling and its
shareholders.  In reaching the decision to recommend the approval of the
Merger Agreement to the shareholders, the Board of Directors, without
assigning any relative or specific weights, considered a number of factors.
For a discussion of such factors, see "TERMS OF THE PROPOSED MERGER -
Background of and Reasons for the Merger; Board Recommendations."

      MBI.  MBI's Board of Directors believes that the Merger will enable
MBI to (i) increase its presence in northwestern Illinois through the
acquisition of an established banking organization and (ii) enhance MBI's
ability to compete in the increasingly competitive banking and financial
services industry.  See "TERMS OF THE PROPOSED MERGER - Background of and
Reasons for the Merger; Board Recommendations."

OPINION OF FINANCIAL ADVISOR TO FIRST STERLING

   
      On July 24, 1995, The Chicago Corporation ("Chicago Corp."), First
Sterling's financial advisor, rendered to the First Sterling Board of
Directors its oral opinion, which was subsequently confirmed by a written
opinion dated as of the date of this Proxy Statement/Prospectus, to the
effect that, as of the dates of such opinions, the consideration to be
received by the holders of First Sterling Common Stock in the Merger was fair
to the shareholders of First Sterling from a financial point of view.
Attached to this Proxy Statement/Prospectus as Annex A is a copy of the
opinion of Chicago Corp., dated November 22, 1995, setting forth the
procedures followed, assumptions made, matters considered and qualifications
and limitations of the review undertaken by Chicago Corp. in connection with
rendering its opinion.  Holders of First Sterling Common Stock are urged to
read Chicago Corp.'s opinion in its entirety.  See "TERMS OF THE PROPOSED
MERGER - Background of and Reasons for the Merger; Board Recommendations" and
"- Opinion of Financial Advisor to First Sterling."
    

FRACTIONAL SHARES

      No fractional shares of MBI Common Stock will be issued to the
shareholders of First Sterling in connection with the Merger.  Each holder of
First Sterling Common Stock who otherwise would have been entitled to receive
a fraction of a share of MBI Common Stock shall receive in lieu


                                    - 11 -
<PAGE> 14

thereof cash, without interest, in an amount equal to the holder's fractional
share interest multiplied by the closing stock price of MBI Common Stock on
the NYSE Composite Tape as reported in The Wall Street Journal on the Closing
Date of the Merger.  Cash received by First Sterling shareholders in lieu of
fractional shares may give rise to taxable income.  See "CERTAIN FEDERAL
INCOME TAX CONSEQUENCES OF THE MERGER."

WAIVER AND AMENDMENT

      Any provision of the Merger Agreement, including, without limitation,
the conditions to the consummation of the Merger and the restrictions
described under the caption "TERMS OF THE PROPOSED MERGER - Business Pending
the Merger," may be (i) waived in writing at any time by the party that is,
or whose shareholders are, entitled to the benefits thereof or (ii) amended
at any time by written agreement of the parties approved by or on behalf of
their respective Boards of Directors, whether before or after the Special
Meeting; provided, however, that after approval of the Merger Agreement by
the shareholders of First Sterling at the Special Meeting no such
modification may (i) alter or change the amount or kind of the consideration
to be received by the First Sterling shareholders in the Merger, (ii)
adversely affect any representation, warranty or covenant of MBI contained in
the Merger Agreement, (iii) adversely affect the tax treatment to the First
Sterling shareholders as a result of receiving shares of MBI Common Stock in
the Merger, (iv) otherwise adversely affect the rights of First Sterling or
any shareholders of First Sterling under the Merger Agreement or (v) impede
or delay receipt of any approvals required for consummation of the Merger or
the consummation of the transactions consummated by the Merger Agreement.

FEDERAL INCOME TAX CONSEQUENCES IN GENERAL

      Thompson & Mitchell, MBI's legal counsel, has delivered its opinion to
the effect that, assuming the Merger occurs in accordance with the Merger
Agreement and conditioned on the accuracy of certain representations made by
MBI, First Sterling and certain shareholders of First Sterling, the Merger
will constitute a "reorganization" for federal income tax purposes and that,
accordingly, no gain or loss will be recognized by First Sterling
shareholders who exchange their shares of First Sterling Common Stock solely
for shares of MBI Common Stock in the Merger.  However, cash received in lieu
of fractional shares may give rise to taxable income.  First Sterling
shareholders who dissent and receive cash in exchange for all of their First
Sterling Common Stock may recognize taxable income, but not in excess of the
amount of cash received.  EACH FIRST STERLING SHAREHOLDER IS URGED TO CONSULT
HIS OR HER OWN TAX ADVISOR TO DETERMINE THE SPECIFIC TAX CONSEQUENCES OF THE
MERGER TO SUCH SHAREHOLDER, INCLUDING THE APPLICABILITY OF VARIOUS STATE,
LOCAL AND FOREIGN TAX LAWS.  See "CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF
THE MERGER."

REGULATORY APPROVAL

   
      The Merger is subject to prior approval of the Federal Reserve Board
and the Illinois Commissioner of Banks and Trust Companies (the "Illinois
Commissioner").  On September 29, 1995, MBI filed two applications regarding
the Merger with the Federal Reserve Board, which granted its approval of the
Merger on November 13, 1995. On October 25, 1995, MBI filed an application
with the Illinois Commissioner seeking such approval.  In reviewing the
applications and the proposed Merger, the Federal Reserve Board considered
various factors, including possible anticompetitive effects of the Merger, and
examined the financial and managerial resources and future prospects of the
combined organization.


                                    - 12 -
<PAGE> 15

No assurance can be given that the approval of the Illinois Commissioner will
be obtained.  See "TERMS OF THE PROPOSED MERGER - Regulatory Approval" and
"SUPERVISION AND REGULATION."
    

ACCOUNTING TREATMENT

      It is intended that the Merger will be accounted for under the
pooling-of-interests method of accounting.  See "TERMS OF THE PROPOSED MERGER
- - Accounting Treatment."

DISSENTERS' RIGHTS

      Under Illinois law, a holder of First Sterling Common Stock may dissent
from the Merger and receive payment of the "fair value" of such shares in
cash if the Merger is consummated by following certain procedures set forth
in Sections 11.65 and 11.70 of the Illinois Business Corporation Act of 1983,
as amended (the "Illinois Statute"), the text of which are attached hereto as
Annex B.  Failure to follow such procedures may result in a loss of
- -------
dissenters' rights.  Any First Sterling shareholder returning a blank
executed proxy card will be deemed to have approved the Merger Agreement,
thereby waiving any such dissenters' rights.  See "RIGHTS OF DISSENTING
SHAREHOLDERS OF STERLING."

MARKETS AND MARKET PRICES

      MBI Common Stock is currently traded on the NYSE under the symbol
"MTL."  Prior to March 25, 1993, MBI Common Stock was quoted on Nasdaq under
the symbol "MTRC."  The closing per share sale price reported for MBI Common
Stock on July 21, 1995, the last trading date preceding the public
announcement of the Merger, was $45.125.  There is no established public
trading market for First Sterling Common Stock.  To the best knowledge of
management of First Sterling, there were no sales of First Sterling Common
Stock in 1993 or 1994 or in 1995 prior to the date of this Proxy
Statement/Prospectus.

GENERAL

   This Proxy Statement/Prospectus is being furnished to holders of First

by MBI of shares of MBI Common Stock upon the consummation of the Merger.
This Proxy Statement/Prospectus and the Notice of Special Meeting, proxy card
and related materials are being first mailed to shareholders of First
Sterling on November 22, 1995.

DATE, TIME AND PLACE

   The Special Meeting will be held at the offices of First Sterling, 300 First
Avenue, Rock Falls, Illinois, on December 22, 1995, at 10:00 a.m. Central
Time.
    

RECORD DATE; VOTE REQUIRED

   On the Record Date, there were 3,685,061 shares of First Sterling Common
Stock outstanding and entitled to vote at the Special Meeting.  Each such
share is entitled to one vote on each matter properly brought before the
Special Meeting.  The affirmative vote of the holders of at least two- thirds
of the outstanding shares of First Sterling Common Stock is required to
approve the Merger Agreement.

   
   As of the Record Date, directors and executive officers of First Sterling
and their affiliates owned beneficially, or controlled the voting of, an
aggregate of 1,659,401 shares of First Sterling Common Stock, or
approximately 45.03% of the outstanding shares of First Sterling Common Stock
entitled to vote at the Special Meeting.  All directors and executive officers
of First Sterling have indicated their intention to vote their shares for the
approval of the Merger Agreement at the Special Meeting.  Additionally, the
directors and certain shareholders of First Sterling each, pursuant to the
terms of his or her respective Voting Agreement, has committed to vote his or
her shares of First Sterling Common Stock for approval of the Merger Agreement.
As of the Record Date, such persons who had executed Voting Agreements or
otherwise indicated they would vote for approval of the Merger Agreement owned
beneficially an aggregate of 2,182,458 shares of First Sterling Common Stock,
or approximately 59.22% of the issued and outstanding shares.  See "TERMS OF
THE PROPOSED MERGER - Other Agreements."
    

VOTING AND REVOCATION OF PROXIES

   Shares of First Sterling Common Stock which are represented by a properly
executed proxy received prior to the vote at the Special Meeting will be
voted at such Special Meeting in the manner directed on the proxy card,
unless such proxy is revoked in the manner set forth herein in advance

                                    - 19 -
<PAGE> 22
of such vote.  ANY FIRST STERLING SHAREHOLDER RETURNING AN EXECUTED PROXY CARD
WHICH DOES NOT PROVIDE INSTRUCTIONS TO VOTE AGAINST THE APPROVAL OF THE
MERGER AGREEMENT WILL BE DEEMED TO HAVE APPROVED THE MERGER AGREEMENT.
Failure to return a properly executed proxy card or to vote in person at the
Special Meeting will have the practical effect of a vote against the approval
of the Merger Agreement.

   Shares subject to abstentions will be treated as shares that are present
and voting at the Special Meeting for purposes of determining the presence of
a quorum.  Such votes will have the effect of votes against the approval of
the Merger Agreement.  Broker "non-votes" (i.e., proxies from brokers or
nominees indicating that such persons have not received instructions from the
beneficial owners or other persons entitled to vote shares with respect to
which the brokers or nominees do not have discretionary power to vote without
such instructions) will be considered as present for the purposes of
determining the presence of a quorum but will not be considered as voting at
the Special Meeting.  Broker non-votes will have the effect of votes against
the approval of the Merger Agreement.

   Any shareholder of First Sterling giving a proxy may revoke it at any time
prior to the vote at the Special Meeting.  Shareholders of First Sterling
wishing to revoke a proxy prior to the vote may do so by delivering to the
Secretary of First Sterling at 305 4th Avenue, Sterling, Illinois  61081 a
written notice of revocation bearing a later date than the proxy or a later
dated proxy relating to the same shares, or by attending the Special Meeting
and voting such shares in person.  Attendance at the Special Meeting will not
in itself constitute the revocation of a proxy.

   The Board of Directors of First Sterling is not currently aware of any
business to be brought before the Special Meeting other than that described
herein.  If, however, other matters are properly brought before such Special
Meeting, or any adjournments or postponements thereof, the persons appointed
as proxies will have discretionary authority to vote the shares represented
by duly executed proxies in accordance with their discretion and judgment as
to the best interest of First Sterling.

SOLICITATION OF PROXIES

   First Sterling will bear its own costs of soliciting proxies, except that
MBI will pay printing and mailing expenses and registration fees incurred in
connection with preparing this Proxy Statement/Prospectus.  Proxies will
initially be solicited by mail, but directors, officers and selected other
employees of First Sterling may also solicit proxies in person or by
telephone.  Directors, executive officers and any other employees of First
Sterling who solicit proxies will not be specially compensated for such
services.  Brokerage houses, nominees, fiduciaries and other custodians will
be requested to forward proxy materials to beneficial owners and will be
reimbursed for their reasonable expenses incurred in sending proxy materials
to beneficial owners.

   HOLDERS OF FIRST STERLING COMMON STOCK ARE REQUESTED TO COMPLETE, DATE AND
SIGN THE ACCOMPANYING PROXY CARD AND RETURN IT PROMPTLY IN THE ENCLOSED
POSTAGE-PREPAID ENVELOPE.

                         TERMS OF THE PROPOSED MERGER
                         ----------------------------

   The following is a summary of the material terms and conditions
of the Merger Agreement, which document is incorporated by reference
herein. This summary is qualified in its entirety by the full text
of the Merger Agreement. MBI, upon written or oral request, will
furnish a copy of the Merger Agreement, without charge, to any
person who receives a copy of this Proxy Statement/Prospectus. Such

                                    - 20 -

requests should be directed to Jon W. Bilstrom, General Counsel and
Secretary, Mercantile Bancorporation Inc., P.O. Box 524, St. Louis,
Missouri 63166-0524, telephone (314) 425-2525.

GENERAL DESCRIPTION OF THE MERGER

   Pursuant to the Merger Agreement, subject to satisfaction or waiver of
certain conditions precedent, including receipt of all applicable regulatory
approvals, First Sterling, an Illinois corporation, will be merged on the
Closing Date with and into Merger Sub, a Missouri corporation which is a
wholly owned subsidiary of MBI.  Upon consummation of the Merger, First
Sterling's corporate existence will terminate and Merger Sub will continue as
the surviving entity.  Simultaneously with the effectiveness of the Merger,
each share of First Sterling Common Stock will be converted into the right to
receive 0.1415 of a share of MBI Common Stock.  Such consideration is subject
to certain anti-dilution protections but is not adjustable based upon the
operating results, financial condition or other factors affecting either MBI
or First Sterling prior to the consummation of the Merger.  The fair market
value of MBI Common Stock received pursuant to the Merger may fluctuate and
at the consummation of the Merger may be more or less than the current fair
market value of such shares.

   The amount and nature of the consideration was established through
arm's-length negotiations between MBI and First Sterling and their respective
advisors, and reflects the balancing of a number of countervailing factors.
The total amount of the consideration reflects a price both parties concluded
was appropriate.  See "- Background of and Reasons for the Merger; Board
Recommendations."  The fact that the consideration is payable in shares of
MBI Common Stock reflects the potential for change in the value of the MBI
Common Stock and the desire of the parties to the Merger to have the
favorable tax attributes of a "reorganization" for federal income tax
purposes.  See "CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER."

   NO ASSURANCE CAN BE GIVEN THAT THE CURRENT FAIR MARKET VALUE OF MBI COMMON
STOCK WILL BE EQUIVALENT TO THE FAIR MARKET VALUE OF MBI COMMON STOCK ON THE
DATE SUCH STOCK IS RECEIVED BY A FIRST STERLING SHAREHOLDER OR AT ANY OTHER
TIME.  THE FAIR MARKET VALUE OF MBI COMMON STOCK RECEIVED BY A FIRST STERLING
SHAREHOLDER MAY BE GREATER OR LESS THAN THE CURRENT FAIR MARKET VALUE OF MBI
COMMON STOCK DUE TO NUMEROUS MARKET FACTORS.

   Following the Closing Date, each shareholder of First Sterling will be
required to submit to the Exchange Agent a properly executed letter of
transmittal and surrender to the Exchange Agent the stock certificate(s)
formerly representing the shares of First Sterling Common Stock in order to
receive a new stock certificate(s) evidencing the shares of MBI Common Stock
to which such shareholder is entitled.  Following the Closing Date, the
Exchange Agent will mail to each First Sterling shareholder a notice of
consummation of the Merger and a form of letter of transmittal, together with
instructions and a return envelope to facilitate the exchange of such
holder's certificate(s) formerly representing First Sterling Common Stock for
certificate(s) evidencing MBI Common Stock.  No dividends or other
distributions will be paid to a former First Sterling shareholder with
respect to shares of MBI Common Stock until such shareholder's letter of
transmittal and stock certificate(s) formerly representing First Sterling
Common Stock, or documentation reasonably acceptable to the Exchange Agent in
lieu of lost or destroyed certificates, is delivered to the Exchange Agent.
See "TERMS OF THE PROPOSED MERGER - Surrender of First Sterling Stock
Certificates and Receipt of MBI Common Stock."  No fractional shares of MBI
Common Stock will be issued in the Merger, but cash will be paid in lieu of
such fractional shares, such cash being calculated by multiplying the
holder's fractional share interest by the closing stock price of MBI
Common Stock on the NYSE Composite Tape as reported in The Wall Street

                                    - 21 -
<PAGE> 24
Journal on the Closing Date of the Merger.  See "- Fractional Shares."
The shares of MBI Common Stock to be issued pursuant to the Merger will
be freely transferable except by certain shareholders of First Sterling
who are deemed to be "affiliates" of First Sterling.  The shares of MBI
Common Stock issued to such affiliates will be restricted in their
transferability in accordance with the rules and regulations promulgated
by the Commission.  See "INFORMATION REGARDING MBI STOCK - Restrictions
on Resale of MBI Stock by Affiliates."

OTHER AGREEMENTS

   
   Concurrent with the execution of the Merger Agreement, MBI and each of the
directors of First Sterling and certain other shareholders of First Sterling
(each of whom is either affiliated with a member of the Board of Directors or
a principal shareholder of First Sterling) executed a separate Voting
Agreement by which each such person agreed that he or she will vote all of
the shares of First Sterling Common Stock that he or she then owned or
subsequently acquires in favor of the approval of the Merger Agreement at the
Special Meeting.  In addition, until the earliest to occur of the Effective
Time of the Merger, the termination of the Voting Agreements or the
abandonment of the Merger, each such person further agreed that he or she
will not vote any such shares in favor of the approval of any other competing
acquisition proposal involving First Sterling and a third party.  Each such
person also agreed that he or she will not transfer shares of First Sterling
Common Stock owned by him or her unless, prior to such transfer, the
transferee executes an agreement in substantially the same form as the Voting
Agreement.  As of the Record Date, persons who had executed Voting Agreements
owned beneficially an aggregate of 2,182,458 shares of First Sterling Common
Stock, or approximately 59.22% of the issued and outstanding shares.
    

INTERESTS OF CERTAIN PERSONS IN THE MERGER

   From and after the Effective Time for a period of not less than five
years, MBI will provide for the indemnification of employees, agents,
directors or officers of First Sterling or any of First Sterling's
subsidiaries, in an amount and of a type not less than that provided by First
Sterling's Articles of Incorporation or bylaws in the form in effect as
of July 24, 1995 or arising by operation of law or arising by virtue of
any contract, resolution or other agreement or document existing as of July
24, 1995.  Further, MBI will assume all duties and obligations of
indemnification of First Sterling or any of First Sterling's subsidiaries
existing as of the Effective Time with respect to any act or omission of any
of their respective employees, agents, directors or officers occurring prior
to the Effective Time; provided, however, that to the extent that First
Sterling's directors' and officers' liability insurance would provide
coverage for any such act or omission, First Sterling agrees to give proper
notice to the insurance carrier and to MBI of a potential claim thereunder so
as to preserve the rights to such insurance coverage.

BACKGROUND OF AND REASONS FOR THE MERGER; BOARD RECOMMENDATIONS

   BACKGROUND OF THE MERGER.  The Board of Directors of First Sterling
periodically reviews First Sterling's strategy in light of general conditions
in the banking industry, local competitive and economic conditions, the
results of its operations and its future prospects, legislative changes, and
other developments affecting the banking industry generally and First
Sterling specifically.  In connection with such review, members of the Board
of Directors and senior management of First Sterling have met from time to
time with representatives of Chicago Corp., First Sterling's financial
advisor, to discuss industry trends and to explore alternative means of
enhancing shareholder value.

   In August 1992, the Board of Directors determined that it was
in the long-term best interests of First Sterling's shareholders,
as well as its depositors, customers, employees and the communities

                                    - 22 -
<PAGE> 25
in which it operates for First Sterling to pursue the possibility of a
business combination between First Sterling and a larger more
geographically diverse bank holding company. The Board of Directors of
First Sterling authorized Chicago Corp. to solicit bank holding companies
with suitable financial strength, stock price performance and prospects,
geographical location and other factors.  Chicago Corp. prepared written
materials with which it solicited expressions of interest from 15 bank
holding companies which Chicago Corp. had identified as the most likely
merger candidates (the "1992 Solicitation").  In Fall 1993, First Sterling
abandoned its merger effort when it was unable to complete a transaction in
connection with such solicitation.  As a result, management undertook a
restructuring of its operations to better enable First Sterling to operate
as an independent entity and to position it for such a combination in the
future.

   In May 1995, Chicago Corp. informed management of First Sterling that MBI
had expressed an interest in acquiring a bank serving communities in
northwestern Illinois.  Representatives of Chicago Corp. and First Sterling
management met in late May and early June to discuss First Sterling's
interest in a combination with MBI, as well as possible values in light of
recent bank merger and acquisition trends, the responses from the 1992
Solicitation and First Sterling's operating results and prospects.  First
Sterling authorized Chicago Corp. to indicate its interest in meeting with
MBI as well as to contact the only bank holding company from the 1992
Solicitation which had expressed a continued interest in First Sterling.
Such bank indicated that it had no current interest in a transaction with
First Sterling.

   In early June, management of First Sterling and MBI held preliminary
discussions relating to a potential combination between the companies which
culminated in representatives of MBI visiting the Sterling and Rock Falls
facilities and surveying the local community.

   On June 13, 1995, First Sterling Board members reviewed with management
the preliminary discussions that had taken place to date and determined that
management should pursue further discussions with MBI.

   On June 14, 1995, the senior management of First Sterling made a
presentation to representatives of MBI concerning its business, operations,
financial results and future prospects.  Thereafter, MBI made a presentation
regarding its history and business philosophy and provided First Sterling
management with financial and other due diligence materials.  At this
meeting, preliminary discussions were held with respect to the terms of the
proposed merger.  Following these discussions, First Sterling allowed MBI to
conduct a due diligence investigation of First Sterling.  Upon completion,
MBI indicated that it was prepared to proceed with the proposed merger and on
July 6, 1995 submitted a proposed form of merger agreement.

   During mid-June, Chicago Corp. provided the First Sterling Board of
Directors with comparative stock data and other financial research and
analyses to supplement the earlier materials provided by MBI.  During mid-
June through early July, members of the Board of Directors held informal
discussions concerning the proposed merger, including the prospects for MBI's
future performance and the advisability of the proposed merger in light of
existing business, economic, competitive and regulatory conditions.

   On July 11, 1995, the Board of Directors reviewed the proposed terms of
the Merger with management.  Following discussions between the directors, the
Board of Directors authorized Messrs. William J. Hank, Carl A. Kautz and
Joseph D. Henderson, members of the Executive Committee of the Board of
Directors, with the assistance of Chicago Corp. and its legal advisors, to
negotiate a definitive merger agreement based on the proposed terms as
described.

                                    -23 -
<PAGE> 26

   During the following two weeks, management of First Sterling, together
with its legal and financial advisors, conducted extensive negotiations with
MBI and its legal advisors.  On July 24, upon completion of the negotiations,
Chicago Corp. rendered its oral opinion that the consideration to be received
by the shareholders of First Sterling was fair to such shareholders from a
financial point of view. See "-Opinion of Financial Advisor to First
Sterling."

   On July 24, 1995, acting by unanimous written consent, the Board of
Directors determined that the Merger Agreement was in the best interest of
First Sterling shareholders and unanimously recommended approval of the
Merger Agreement.

   FIRST STERLING'S REASONS AND BOARD RECOMMENDATION.  The Board of
Directors of First Sterling believes that the Merger is in the best interests
of First Sterling and its shareholders.  In determining to recommend that the
holders of First Sterling Common Stock approve the Merger and the Merger
Agreement, and in determining the fairness of the terms of the Merger and the
terms of the provisions of the Merger Agreement, the First Sterling Board of
Directors considered the principal factors described below.

      (1)   The financial condition, assets, results of operations, business
and prospects of First Sterling as an independent entity and the risks
involved in achieving those prospects.

      (2)   The opinion of Chicago Corp. to the effect that, as of the date
of such opinion, the consideration to be received in the Merger by the
holders of First Sterling Common Stock, as provided in the Merger Agreement,
is fair from a financial point of view.  See "- Opinion of Financial Advisor
of First Sterling" for a description of the financial analyses undertaken by
Chicago Corp. and the assumptions and qualifications made by Chicago Corp. in
connection therewith.

      (3)   Economic conditions and prospects for the markets in which First
Sterling operates, and the competitive pressures in the financial service
industry in general and the banking industry in particular.

      (4)   That the Merger presented the holders of First Sterling Common
Stock the opportunity to receive higher dividends, liquidity for their shares
and better prospects for future growth than if First Sterling were to remain
independent.

      (5)   The trading and dividend history of MBI Common Stock and the
prospects for the price of and dividends on the MBI Common Stock.

      (6)   The terms and conditions of the Merger Agreement, including the
amount and sufficiency of the consideration to be paid to the holders of
First Sterling Common Stock, as well as the intended tax deferred nature of
the Merger for First Sterling shareholders.

      (7)   That a business combination with a larger bank holding company
such as MBI would provide greater short-term and long-term value to First
Sterling shareholders than other available alternatives and would enhance
First Sterling's competitiveness and its ability to serve its depositors,
customers and the communities in which it operates.

   The First Sterling Board of Directors based its determination that the
terms of the Merger and the terms and conditions of the Merger Agreement were
fair to the holders of First Sterling Common Stock on, among other things,
the fairness opinion of Chicago Corp. and the other factors described above.

                                    - 24 -

   THE BOARD OF DIRECTORS OF FIRST STERLING UNANIMOUSLY RECOMMENDS THAT
SHAREHOLDERS OF FIRST STERLING VOTE FOR THE PROPOSAL TO APPROVE THE MERGER
                                    ---
AGREEMENT.

   MBI'S REASONS AND BOARD RECOMMENDATIONS.  The Executive Committee
of the Board of Directors of MBI considered a number of factors, including,
among other things, the financial condition of First Sterling and projected
synergies which are anticipated to result from the Merger.  The Executive
Committee concluded that the Merger presents an unique opportunity for MBI to
increase its presence in northwestern Illinois through the acquisition of an
established banking organization having operations in the targeted area.
MBI's decision to pursue discussions with First Sterling was primarily a
result of MBI's assessment of the value of First Sterling's banking
franchise, its substantial asset base within that area and the compatibility
of the businesses of the two banking organizations.

OPINION OF FINANCIAL ADVISOR TO FIRST STERLING

   Chicago Corp. was retained by the First Sterling Board of Directors, among
other things, to advise it as to the fairness from a financial point of view
of the consideration to be received by the holders of the First Sterling
Common Stock in the Merger and to assist it in its negotiations with MBI.

   Chicago Corp. is a recognized specialist in the financial services
industry in general and in Midwestern banks in particular.  Chicago Corp. is
regularly engaged in advising financial institutions with respect to mergers
and acquisitions as well as raising debt and equity capital for such
institutions.  The First Sterling Board of Directors selected Chicago Corp.
on the basis of its ability to evaluate the fairness of the consideration to
be received in the Merger, its qualifications, past experience with and
knowledge of First Sterling and its reputation in the banking and investment
banking communities.

   On July 24, 1995, Chicago Corp. rendered its oral opinion, which was
subsequently confirmed by a written opinion dated as of the date of this
Proxy Statement/Prospectus, to the effect that, as of such dates, the
consideration to be received by the holders of First Sterling Common Stock in
the Merger is fair to such shareholders from a financial point of view.  The
full text of Chicago Corp.'s written opinion, which sets forth the procedures
followed, assumptions made, matters considered and qualifications and
limitations of the review undertaken in connection therewith by Chicago Corp.
is attached as Annex A to this Proxy Statement/Prospectus and is
               -------
incorporated herein by reference in its entirety.  In preparing the opinion,
Chicago Corp. assumed and relied upon the accuracy and completeness of all
financial and other information reviewed by it for purposes of the opinion
and did not independently verify such information or undertake an independent
evaluation or appraisal of the assets or liabilities of First Sterling or MBI
nor was it furnished with any such evaluation or appraisal.  Chicago Corp. is
not an expert in the evaluation of allowances for loan losses, and it has not
made an independent evaluation of the adequacy of the allowance for loan
losses of First Sterling or MBI nor has it reviewed any individual credit
files, and it assumed that the aggregate allowances for loan losses are
adequate to cover such losses.  Chicago Corp.'s opinion is necessarily based
on economic, market and other conditions as in effect on, and the information
made available to it as of, the date of such opinion.  HOLDERS OF SHARES OF
FIRST STERLING COMMON STOCK ARE URGED TO READ CHICAGO CORP.'S OPINION IN ITS
ENTIRETY.

   In performing its analyses and arriving at its opinion, Chicago Corp.
considered such financial and other factors as it deemed appropriate
and feasible under the circumstances, including, among other things:
(i) audited   and unaudited financial statements of First Sterling
and MBI through September 30, 1995; (ii) certain information,
including financial and other material relating to the businesses,
earnings, assets and prospects of First Sterling and MBI furnished to
Chicago Corp. by First Sterling and MBI; (iii) information gathered
during limited discussions with members of the senior managements of

                                    - 25 -
<PAGE> 28
First Sterling and MBI concerning the businesses and financial prospects
of the respective companies; (iv) the historical market prices and
trading activity of the First Sterling Common Stock and the MBI Common Stock
and other publicly traded stocks Chicago Corp. deemed to be relevant; (v) the
financial performance of First Sterling, MBI and other companies Chicago
Corp. deemed to be relevant; (vi) the proposed financial terms of the Merger
and the financial terms of selected other mergers and acquisitions Chicago
Corp. deemed to be relevant; (vii) the Merger Agreement and related
agreements; (viii) the pro forma effects of the Merger on First Sterling's
earnings, dividends and book value; and (ix) such other financial analyses as
Chicago Corp. deemed relevant.

   Generally, Chicago Corp.'s preparation of the fairness opinion involved
various determinations as to the most appropriate and relevant methods of
financial analysis and the application of those methods to particular
circumstances.  Therefore, such an opinion is not readily susceptible to
summary description.  Furthermore, in arriving at its opinion, Chicago Corp.
did not attribute any particular weight to any analysis or factor considered
by it, but rather made qualitative judgments as to the significance and
relevance of each analysis and factor.  Accordingly, Chicago Corp. believes
that its analyses must be considered as a whole and that considering any
portions of such analyses and of the factors considered therein, without
considering all analyses and factors, could create a misleading or incomplete
view of the process underlying its opinion.  In its analyses, Chicago Corp.
made assumptions with respect to industry performance, general business and
economic conditions and other matters, many of which are beyond the control
of First Sterling or MBI.  Any estimates contained in such analyses are not
necessarily indicative of actual values or predictive of future results or
values, which may be significantly more or less favorable than those
suggested by such analyses.  In addition, Chicago Corp.'s analyses and
estimates of value do not purport to be appraisals or necessarily to reflect
the prices at which First Sterling or any shares of First Sterling Common
Stock may be sold.  Accordingly, because such estimates are inherently
subject to uncertainty, none of First Sterling, MBI or Chicago Corp. or any
other person assumes responsibility for their accuracy.

   NET PRESENT VALUE ANALYSIS.  Chicago Corp. prepared a net present
value analysis which indicated theoretical values for First Sterling Common
Stock based on return on average assets ranging between 0.8% and 1.3% and
asset growth rates ranging between 0.0% and 8.0% over a four-year period.
The results of this analysis indicated an implied value reference range for
First Sterling Common Stock between $3.02 per share (0.8% return on average
assets; 0.0% asset growth rate) and $6.25 per share (1.3% return on average
assets; 8.0% asset growth rate).  At a return on average assets ratio of
1.1%, which approximates First Sterling's recent historical performance,
Chicago Corp. derived an implied value reference range for the First Sterling
Common Stock between $4.13 per share (0.0% asset growth rate) and $5.30 per
share (8.0% asset growth rate).  At an asset growth rate of 0.0%, which
approximates First Sterling's recent historical performance, Chicago Corp.
derived an implied value reference range for the First Sterling Common Stock
between $3.02 per share (0.8% return on average assets) and $4.86 per share
(1.3% return on average assets).  Based on the market price of MBI Common
Stock on July 24, 1995 and the exchange ratio in the Merger of 0.1415, the
value of the offer from MBI was $6.40 per share.

   CONTRIBUTION ANALYSIS.  Chicago Corp. prepared a contribution analysis
showing the percentages of assets, deposits, tangible equity, 1994 net income
and estimated 1995 and 1996 net income contributed to the combined company on
a pro forma basis by First Sterling and MBI, and compared these percentages
to the pro forma ownership of MBI.  This analysis showed that First Sterling,
as of March 31, 1995, would have contributed, on a pro forma consolidated
basis, 1.23% of total assets, 1.31% of deposits, 1.53% of tangible equity,
1.14% of calendar 1994 net income, 1.07% of calendar 1995 estimated net
income and 1.05% of calendar 1996 estimated net income.  Based on the
exchange ratio in the Merger of 0.1415, holders of First Sterling Common
Stock would have owned approximately 1.13% of the MBI Common Stock
outstanding as of March 31, 1995 (after giving effect to the Merger as of
that date).

   COMPARABLE TRANSACTION ANALYSIS.  Chicago Corp. reviewed selected
merger and acquisition transactions that it deemed to be comparable. The
following merger transactions were reviewed based on publicly available
data (the acquiror is named first and underlined, followed by the seller);
AMBANC Corp., First Robinson Bancorp; AMCORE Financial, Inc., NBM Bancorp;
- ------------                          ----------------------
Community First Banks, Minowa Bancshares; CNB Bancshares, Inc., Harrisburg
- ---------------------                     --------------------
Bancshares; Marshall & Ilsley, Bank of Burlington; Mercantile Bancorporation
            -----------------                      -------------------------
Inc., Wedge Bank; Lauritzen Corp., Shelby County Bancshares; AMCORE Financial,
- ----              ---------------                            ----------------
Inc., First State Bancorp; Banc One Corporation, Mid States Bancshares; F&M
- ----                       --------------------                         ---
Bancorporation, First National Financial.
- --------------
    

   Transactions were selected on the basis of the comparability of absolute
transaction value and the comparability of the markets served by the acquired
institutions to those of First Sterling.  Chicago Corp. calculated the
multiples of offer price to last twelve months ("LTM") earnings per share and
tangible book value per share of the acquired company in each such
transaction.  For the comparable transactions, the multiple of offer price to
LTM earnings ranged from 9.29 to 17.85 with an average of 13.64.  The value
to be received by the holders of First Sterling Common Stock under the terms
of the Merger Agreement (based on the market price of MBI Common Stock of
$45.25 per share on July 24, 1995 and an exchange ratio of 0.1415) represents
a multiple of offer price to LTM earnings of 13.49.  For the comparable
transactions, the multiple of offer price to tangible book value ranged from
1.39 to 2.16 with an average of 1.73.  The terms of the Merger represent a
multiple of offer price to tangible book value per share (as of March 31,
1995) of 1.42.

   FINANCIAL IMPLICATIONS TO FIRST STERLING SHAREHOLDERS.  Chicago
Corp. prepared an analysis of the financial implications of the terms of the
Merger to a holder of First Sterling Common Stock.  This analysis indicated
that on a pro forma equivalent basis a shareholder of First Sterling would
achieve increases in earnings per share and per share dividends and a
decrease in book value per share as a result of the consummation of the
Merger.

   COMPARATIVE SHAREHOLDER RETURNS.  Chicago Corp. analyzed and
compared projected shareholder returns under several scenarios, including
First Sterling remaining independent, the Merger being effected in 1995 and
the Merger being effected in 1998.  This comparative analysis, which was
based on the net present value of projected dividend streams and projected
valuations of the First Sterling Common Stock as of 1998 (using current
price-to-earnings multiples), indicated total annual returns for First
Sterling shareholders of 19.83% if First Sterling remains independent, 22.32%
if the Merger is consummated in 1998 (on terms similar to those set forth in
the Merger Agreement) and 23.21% if the Merger is consummated in 1995.

   COMPARABLE COMPANY ANALYSIS.  Chicago Corp. compared the market
price, market-to-book value and price-to-earnings multiples of MBI Common
Stock with the individual market multiples and averages of the following
selected comparable companies which it deemed to be reasonably similar to MBI
in size, financial character, operating character, historical performance
and/or geographic market:  Banc One Corporation; Norwest Corporation; First
Bank System, Inc.; Boatmen's Bancshares, Inc.; First of America Bank Corp.;
Firstar Corporation; Old Kent Financial Corporation; Commerce Bancshares,
Inc.; UMB Financial Corporation; and Magna Group, Inc. (collectively, the
"Comparable Companies").  This analysis indicated that MBI Common Stock sold
at a price of 1.83 times tangible book value as of March 31, 1995 and the
Comparable Companies sold at an average price of 1.88 times tangible book
value as of March 31, 1995.  As of March 31, 1995, the MBI Common Stock sold
at a multiple of price to LTM earnings of 11.32 while the average
price-to-earnings multiple for the Comparable Companies was 12.41.

   Chicago Corp.'s opinion issued as of the date of this Proxy
Statement/Prospectus is based on the financial and other information
reviewed by Chicago Corp. in rendering its July 24, 1995 oral

                                    - 27 -
<PAGE> 30
opinion, a review of information set forth in this Proxy Statement/Prospectus
and a review of financial results of MBI and First Sterling since July 24,
1995.

   Other than its engagement by First Sterling in connection with the Merger,
the 1992 Solicitation and its engagement by one of First Sterling's principal
shareholders in connection with a transaction unrelated to the Merger, for
which it received customary compensation, Chicago Corp. has not provided any
advisory services to First Sterling or its directors, officers or principal
shareholders.  For its financial advisory services to First Sterling in
connection with the Merger, upon closing of the Merger, Chicago Corp. will be
paid a fee of 1.00% of the total consideration to be received by First
Sterling.  In addition, First Sterling has agreed to pay Chicago Corp.'s
out-of-pocket expenses, and to indemnify Chicago Corp. against certain
liabilities, including liabilities arising under the Federal securities laws.

   Chicago Corp. is a member of all principal United States securities
exchanges and, in the conduct of its broker-dealer activities, may from time
to time purchase securities from, and sell securities to, First Sterling and
MBI.

Date, whether before or after approval by the shareholders of First Sterling,

MBI and the respective Boards of Directors of First Sterling and Merger Sub,
or (ii) unilaterally by the Executive Committee of the Board of Directors of
MBI or the Boards of Directors of First Sterling or Merger Sub:  (A) at any
time after April 30, 1996, if the Merger has not been consummated by such
date (provided that the terminating party is not then in material breach of
any representation, warranty, covenant or other agreement contained in the
Merger Agreement); (B) if the Federal Reserve Board or any other federal
and/or state regulatory authority whose approval is required for consummation
of the Merger shall have issued a final nonappealable denial of such

Mercantile may terminate the Agreement in certain circumstances if First
Sterling acquires property after July 24, 1995 and if environmental
investigations of such acquired property, together with all previously
acquired property after such date, indicates that the estimated cost of
corrective or remedial action with regard to such properties would exceed
$100,000 in the aggregate.  No assurance can be given that the Merger will be
consummated on or before April 30, 1996 or that MBI,

                                    - 30 -
<PAGE> 33
Merger Sub or First Sterling will not elect to terminate the Merger Agreement
if the Merger has not been consummated on or before such date.

   In the event of the termination of the Merger Agreement, it shall become
void and there shall be no liability on the part of any party except, that
(i) confidentiality and indemnification obligations shall survive
termination, (ii) MBI shall pay all printing, mailing and filing expenses
with respect to the Registration Statement and this Proxy
Statement/Prospectus and (iii) in the case of termination due to continued
material breach after notice and opportunity to cure, the breaching party
shall not be relieved of liability to the nonbreaching party arising from the
willful nonperformance of any covenant in the Merger Agreement.

   Any provision of the Merger Agreement, including, without limitation, the
conditions to the consummation of the Merger and the restrictions described
under "- Business Pending the Merger," may be (i) waived in writing at any
time by the party that is, or whose shareholders are, entitled to the
benefits thereof, or (ii) amended at any time by written agreement of the
parties approved by or on behalf of their respective Boards of Directors or
Executive Committees, whether before or after the Special Meeting; provided,

First Sterling at the Special Meeting no such modification may (i) alter or

   First Sterling, MBI and Merger Sub have agreed to indemnify each other and
the officers, directors and controlling persons of each other against any
losses, claims, damages or liabilities to which any such party may become
subject under federal or state laws or regulations, to the extent that such
loss, claim, damage or liability is based primarily upon information
furnished to the party subject to such liability by the other party, or out
of an omission by such other party to state a necessary or material fact in
the Registration Statement of which this Proxy Statement/Prospectus is a
part.

CLOSING DATE

   
   The Merger will be consummated and become effective on the Closing Date
upon issuance of a certificate of merger by the Missouri Secretary of State.
Under the Merger Agreement, unless otherwise agreed to by the parties, the
Closing Date shall be the later to occur of (i) January 2, 1996 and (ii) the
first business day of the first full calendar month beginning at least five
business days after the month in which the later of the following events
occurs: (a) the receipt of the requisite approval of the Merger Agreement by
the shareholders of First Sterling; and (b) the approval of the Merger by the
Federal Reserve Board and any other federal and/or state regulatory agency
whose approval is required, and all waiting periods for such approvals have
been satisfied.
    

SURRENDER OF FIRST STERLING STOCK CERTIFICATES AND RECEIPT OF MBI COMMON
STOCK

   At the Effective Time of the Merger, each outstanding share of First
Sterling Common Stock will be converted into the right to receive 0.1415 of a
share of MBI Common Stock.  See "- General Description of the Merger."  Each
holder of First Sterling Common Stock, upon submission to the Exchange Agent
of a properly executed letter of transmittal and surrender to the Exchange
Agent

                                    - 31 -
<PAGE> 34
of the stock certificate(s) formerly representing shares of First
Sterling Common Stock, will be entitled to receive a stock certificate(s)
evidencing the shares of MBI Common Stock to which such shareholder is
entitled.

   As soon as practicable following the Effective Time, the Exchange Agent
will mail to each First Sterling shareholder of record as of the Effective
Time notification of the consummation of the Merger.  The Exchange Agent will
also provide a letter of transmittal and instructions as to the procedure for
the surrender of the stock certificates evidencing the First Sterling Common
Stock and the receipt of shares of MBI Common Stock.  It will be the
responsibility of each holder of First Sterling shares to submit all
certificates formerly evidencing such holder's shares of First Sterling
Common Stock to the Exchange Agent.  No dividends or other distribution will
be paid to a former First Sterling shareholder with respect to shares of MBI
Common Stock until such shareholder's properly completed letter of
transmittal and stock certificates formerly representing First Sterling
Common Stock, or, in lieu thereof, such evidence of a lost, stolen or
destroyed certificate and/or such insurance bond as the Exchange Agent may
reasonably require in accordance with customary exchange practices, are
delivered to the Exchange Agent.  All dividends or other distributions on the
MBI Common Stock declared between the Closing Date of the Merger and the date
of the surrender of a First Sterling stock certificate will be held for the
benefit of the shareholder and will be paid to the shareholder, without
interest thereon, upon the surrender of such stock certificate(s) or
documentation and/or insurance bond in lieu thereof.

FRACTIONAL SHARES

   No fractional shares of MBI Common Stock will be issued to the former
shareholders of First Sterling in connection with the Merger.  Each holder of
First Sterling Common Stock who otherwise would have been entitled to receive
a fraction of a share of MBI Common Stock shall receive in lieu thereof cash,
without interest, in an amount equal to the holder's fractional share
interest multiplied by the closing stock price of MBI Common Stock on the
NYSE Composite Tape as reported in The Wall Street Journal on the Closing
Date.  Cash received by First Sterling shareholders in lieu of fractional
shares may give rise to taxable income.  See "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER."

REGULATORY APPROVAL

   
   In addition to the approval of the Merger Agreement by the First Sterling
shareholders, the obligations of the parties to effect the Merger are subject
to prior approval of the Federal Reserve Board and the Illinois Commissioner.
As a bank holding company, MBI is subject to regulation under the BHCA. The
Federal Reserve Board granted its approval of the Merger on November 13, 1995.

   Under the BHCA, the Federal Reserve Board could have withheld approval of
the Merger if, among other things, it had determined that the effect of the
Merger would be to substantially lessen competition in the relevant market.
In addition, the Federal Reserve Board was required to consider whether the
combined organization meets the requirements of the Community Reinvestment Act
of 1977, as amended, by assessing the involved entities' respective records of
meeting the credit needs of the local communities in which they are chartered,
consistent with the safe and sound operation of such institutions. In its
review, the Federal Reserve Board was also required to examine the financial
and managerial resources and future prospects of the combined organization and
analyze the capital structure and soundness of the resulting entity.  The
Federal Reserve Board had the authority to deny the application if it had
concluded that the combined organization would have inadequate capital.  MBI
has also filed an application with the Illinois Commissioner, which will
review the record of MBI's subsidiary financial

                                    - 32 -
<PAGE> 35
institutions in meeting the credit needs of the local communities they serve.
Such application is currently pending.

   The Merger cannot be consummated prior to receipt of all required approvals.
There can be no assurance that required regulatory approvals for the Merger
will be obtained, and, if the Merger is approved, as to the date of such
approvals or whether the approvals will contain any unacceptable conditions.
There can likewise be no assurance that the United States Department of
Justice
will not challenge the Merger during the waiting period set aside for
such challenges after receipt of approval from the Federal Reserve
Board.  See "SUPERVISION AND REGULATION."
    

   MBI and First Sterling are not aware of any governmental approvals or
actions that may be required for consummation of the Merger other than as
described above.  Should any other approval or action be required, it is
presently contemplated that such approval or action would be sought.  There
can be no assurance that any necessary regulatory approvals or actions will
be timely received or taken, that no action will be brought challenging such
approval or action or, if such a challenge is brought, as to the result
thereof, or that any such approval or action will not be conditioned in a
manner that would cause the parties to abandon the Merger.  See "SUPERVISION
AND REGULATION."

BUSINESS PENDING THE MERGER

   The Merger Agreement provides that, during the period from July 24, 1995
to the Effective Time, First Sterling will conduct its business according to
the ordinary and usual course consistent with past practices and use its best
efforts to maintain and preserve its business organization, employees and
advantageous business relationships and retain the services of its officers
and key employees.

   Furthermore, from July 24, 1995 to the Effective Time, except as provided
in the Merger Agreement, First Sterling will not, and will not permit any of
its subsidiaries to, without the prior written consent of MBI:

   directly or indirectly, in respect of its capital stock (other than dividends
   from any of the First Sterling subsidiaries to First Sterling), except that

   per share for any quarter in which First Sterling shareholders shall not be
   entitled to dividends on MBI Common Stock issued in the Merger;

         (2)   enter into or amend any employment, severance or similar

   in compensation to employees consistent with past practice, or as required by
   law or contract, and except for such increases of which First Sterling
   notifies MBI in writing and which MBI does not disapprove within ten days of
   the receipt of such notice;

         (3)   authorize, recommend, propose or announce an intention to
   authorize, recommend or propose, or enter into an agreement in principle with
   respect to, any merger, consolidation or business combination (other than the

   disposition of a material amount of assets or securities or any release or
   relinquishment of any material contract rights;

         (6)   purchase, redeem, retire, repurchase or exchange, or otherwise
   acquire or dispose of, directly or indirectly, any capital stock, options,
   warrants, conversion rights or other rights, whether pursuant to the terms of
   such capital stock, options, warrants, conversion rights or other rights or
   otherwise;

         (7)   (i) without first consulting with MBI, enter into, renew or
   increase any loan or credit commitment (including stand-by letters of credit)
   to, or invest or agree to invest in any person or entity or modify any of the
   material provisions or renew or otherwise extend the maturity date of any
   existing loan or credit commitment (collectively, "Lend to") in an amount in
   excess of $200,000 with respect to commercial transactions, $300,000 with
   respect to residential transactions, or in any amount which, when aggregated
   with any and all loans or credit commitments of First Sterling and its
   subsidiaries to such person or entity, would be in excess of $350,000; (ii)
   without first obtaining the written consent of MBI, Lend to any person or
   entity in an amount in excess of $500,000 or in any amount which, when
   aggregated with any and all loans or credit commitments of First Sterling and
   its subsidiaries to such person or entity, would be in excess of $750,000;
   (iii) Lend to any person other than in accordance with lending policies as in
   effect on July 24, 1995, except that in the case of clauses (i) and (ii)
   hereof, First Sterling or any of its subsidiaries may make any such loan in
   the event (A) First Sterling or any of its subsidiaries has delivered to MBI
   or Merger Sub or their designated representative a notice of its intention to
   make such loan and such information as their designated representative may
   reasonably require in respect thereof and (B) MBI or Merger Sub or their
   designated representative shall not have reasonably objected to such loan by
   giving written or facsimile notice of such objection within two business days
   following the delivery to MBI or Merger Sub or their designated
   representative of the notice of intention and information as aforesaid; or
   (iv) Lend to any person or entity any of the loans or other extensions of
   credit to which or investments in which are on a "watch list" or similar
   internal report of First Sterling or any subsidiary of First Sterling (except
   those denoted "pass" thereon), in an amount in excess of $100,000; provided,
   however, that First Sterling and any First Sterling subsidiary shall not be
   prohibited from honoring any contractual obligation in existence on July 24,
   1995.  Notwithstanding clauses (i) and (ii), First Sterling shall be
   authorized, without first consulting with MBI or obtaining MBI's prior
   written consent, to increase the aggregate amount of the credit facilities
   theretofore established in favor of any person or entity (the "Pre-Existing
   Facilities"), provided that the aggregate amount of any and all such
   increases shall not be in excess of five percent (5%) of such Pre-Existing
   Facilities or $25,000, whichever is greater;

         (8)   directly or indirectly, including through its officers,
   directors, employees or other representatives:

   The Merger Agreement also provides that during the period from July 24,
1995 to the Effective Time, MBI and Merger Sub shall not, and shall not
permit any of their subsidiaries to, without the prior written consent of
First Sterling, agree in writing or otherwise take any action that is
prohibited of First Sterling by subsections (9) and (12) above.

ACCOUNTING TREATMENT

   The Merger is intended to be accounted for under the pooling-of-interests
method of accounting.  It is a condition to MBI's and Merger Sub's
consummation of the Merger, unless otherwise waived, that KPMG Peat Marwick
LLP, MBI's independent accountants, deliver to MBI and Merger Sub an opinion
that the Merger will qualify for pooling-of-interests accounting treatment.

             CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
             -----------------------------------------------------

   The following discussion is based upon an opinion prepared by Thompson &
Mitchell, counsel to MBI ("Counsel"), and, except as otherwise indicated,
reflects Counsel's opinion.  The discussion is a general summary of the
material federal income tax consequences of the Merger to certain First
Sterling shareholders and does not purport to be a complete analysis or
listing of all potential tax effects relevant to a decision whether to vote
for the approval of the Merger.  The discussion does not address all aspects
of federal income taxation that may be applicable to First Sterling
shareholders, and does not address the consequences of the Merger to First
Sterling shareholders subject to special federal income tax treatment
including (without limitation) foreign persons, insurance companies,
tax-exempt entities, retirement plans, dealers in securities and persons who
acquired their First Sterling Common Stock pursuant to the exercise of
employee stock options or otherwise as compensation.  The discussion
addresses neither the effect of any applicable state, local or foreign tax
laws, nor the effect of any federal tax laws other than those pertaining to
federal income taxes. IN VIEW OF THE INDIVIDUAL NATURE OF FEDERAL INCOME TAX
CONSEQUENCES, EACH FIRST STERLING SHAREHOLDER IS URGED TO CONSULT HIS OR HER
OWN TAX ADVISOR TO DETERMINE THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO
SUCH SHAREHOLDER.

   The discussion is based on the Code, regulations proposed or promulgated
thereunder, current administrative rulings and practice, and judicial
precedent, all of which are subject to change.  Any such change, which may or
may not be retroactive, could alter the tax consequences discussed herein.
The discussion is also based on certain assumptions regarding the factual
circumstances that will exist at the Effective Time of the Merger, including
certain representations of MBI, First Sterling and certain shareholders of
First Sterling.  If any of these factual assumptions is inaccurate, the tax
consequences of the Merger could differ from those described herein.  The
discussion assumes that shares of First Sterling Common Stock are held as
capital assets (within the meaning of Section 1221 of the Code) at the
Effective Time.

   Assuming the Merger occurs in accordance with the Merger Agreement, the
Merger will constitute a "reorganization" for federal income tax purposes
under Section 368(a)(1)(A) of the Code, by reason of the application of
Section 368(a)(2)(D) of the Code, with the following federal income tax
consequences:

         (1)   First Sterling shareholders will recognize no gain or loss as a
   result of the exchange of their First Sterling Common Stock solely for shares
   of MBI Common Stock pursuant to the Merger, except with respect to cash
   received in lieu of fractional shares, if any, as discussed below.

                                    - 36 -
<PAGE> 39

         (2)   The aggregate adjusted tax basis of the shares of MBI Common
   Stock received by each First Sterling shareholder in the Merger (including
   any fractional share of MBI Common Stock deemed to be received, as described
   in paragraph (4) below) will be equal to the aggregate adjusted tax basis of
   the shares of First Sterling Common Stock surrendered.

         (3)   The holding period of the shares of MBI Common Stock received by
   each First Sterling shareholder in the Merger (including any fractional share
   of MBI Common Stock deemed to be received, as described in paragraph (4)
   below) will include the holding period of the shares of First Sterling Common
   Stock exchanged therefor.

         (4)   A First Sterling shareholder who receives cash in the Merger in
   lieu of a fractional share of MBI Common Stock will be treated as if the
   fractional share had been received by the shareholder in the Merger and then
   redeemed by MBI in return for the cash.  The receipt of such cash will cause
   the recipient to recognize capital gain or loss equal to the difference
   between the amount of cash received and the portion of such holder's adjusted
   tax basis in the shares of MBI Common Stock allocable to the fractional
   share.

         (5)   A First Sterling shareholder who receives only cash as a result
   of the exercise of dissenters' rights will realize gain or loss for federal
   income tax purposes (determined separately as to each block of First Sterling
   Common Stock exchanged) in an amount equal to the difference between (x) the
   amount of cash received by such shareholder, and (y) such shareholder's tax
   basis for the shares of First Sterling Common Stock surrendered in exchange
   therefor, provided that the cash payment does not have the effect of the
   distribution of a dividend.  Any such gain or loss will be recognized for
   federal income tax purposes and will be treated as capital gain or loss.
   However, if the cash payment does have the effect of the distribution of a
   dividend, the amount of taxable income recognized generally will equal the
   amount of cash received; such income generally will be taxable as a dividend;
   and no loss (or other recovery of such shareholder's tax basis for the shares
   of First Sterling Common Stock surrendered in the exchange) generally will be
   recognized by such shareholder.  The determination of whether a cash payment
   has the effect of the distribution of a dividend will be made pursuant to the
   provisions and limitations of Section 302 of the Code, taking into account
   the constructive stock ownership rules of Section 318 of the Code.  See
   "Impact of Section 302 of the Code," below.

   IMPACT OF SECTION 302 OF THE CODE.  With regard to dissenters, the
determination of whether a cash payment has the effect of the distribution of
a dividend generally will be made pursuant to the provisions of Section 302
of the Code.  A cash payment to a First Sterling shareholder will be
considered not to have the effect of the distribution of a dividend under
Section 302 of the Code and such shareholder will recognize capital gain or
loss only if the cash payment (i) results in a "complete redemption" of such
shareholder's actual and constructive stock interest, (ii) results in a
"substantially disproportionate" reduction in such shareholder's actual and
constructive stock interest or (iii) is "not essentially equivalent to a
dividend."

   A cash payment will result in a "complete redemption" of a shareholder's
stock interest if such shareholder does not actually or constructively own
any stock after the receipt of the cash payment.  A reduction in a
shareholder's stock interest will be "substantially disproportionate" if (i)
the percentage of outstanding shares actually and constructively owned by
such shareholder after the receipt of the cash


                                    - 37 -
<PAGE> 40
payment is less than four-fifths (i.e., 80%) of the percentage of outstanding
                                  ----
shares actually and constructively owned by such shareholder immediately
prior to the receipt of the cash payment and (ii) such shareholder actually
and constructively owns less than 50% of the number of shares outstanding
after the receipt of the cash payment.  A cash payment will qualify as "not
essentially equivalent to a dividend" if it results in a meaningful reduction
in the percentage of outstanding shares actually and constructively owned by
such shareholder.  No specific tests apply to determine whether a reduction
in a shareholder's ownership interest is meaningful; rather, such
determination will be made based on all the facts and circumstances
applicable to such First Sterling shareholder.  No general guidelines
dictating the appropriate interpretation of facts and circumstances have been
announced by the courts or issued by the Internal Revenue Service (the
"Service").  However, the Service has indicated in Revenue Ruling 76-385 that
a minority shareholder (i.e., a holder who exercises no control over
                        ----
corporate affairs and whose proportionate stock interest is minimal in
relation to the number of shares outstanding) generally is treated as having
had a "meaningful reduction" in interest if a cash payment reduces such
holder's actual and constructive stock ownership by even a small amount.

   Under the traditional analysis (which apparently continues to be used by
the Service), Section 302 of the Code will apply as though the cash payment
were made by First Sterling in a hypothetical redemption of First Sterling
Common Stock immediately prior to, and in a transaction separate from, the
Merger (a "deemed First Sterling redemption").  Thus, under the traditional
analysis, the determination of whether a cash payment results in a complete
redemption of interest, qualifies as a substantially disproportionate
reduction of interest, or is not essentially equivalent to a dividend will be
made by comparing (x) the shareholder's actual and constructive stock
interest in First Sterling before the deemed First Sterling redemption, with
(y) such shareholder's actual and constructive stock interest in First
Sterling after the deemed First Sterling redemption (but before the Merger).
However, the law is unclear regarding whether the deemed redemption approach
of the Service is correct, and Counsel has rendered no opinion on the
correctness of the Service's approach.  Counsel has noted in its opinion that
some tax practitioners believe that the determination of whether a cash
payment has the effect of a distribution of a dividend should be made as if
the First Sterling Common Stock exchanged for cash in the Merger had instead
been exchanged in the Merger for shares of MBI Common Stock followed
immediately by a redemption of such shares by MBI for the cash payment (a
"deemed MBI redemption").  Under this analysis, the determination of whether
a cash payment satisfies any of the foregoing tests would be made by
comparing (i) the shareholder's actual and constructive stock interest in MBI
before the deemed MBI redemption (determined as if such shareholder had
received solely MBI Common Stock in the Merger) with (ii) such shareholder's
actual and constructive stock interest in MBI after the deemed MBI
redemption.  Because this analysis may be more likely to result in capital
gain treatment than the traditional analysis, each First Sterling shareholder
who receives solely cash in exchange for all of the First Sterling Common
Stock he or she actually owns should consult his or her own tax advisor with
regard to the proper treatment of such cash.

   The determination of ownership for purposes of the three foregoing tests
will be made by taking into account both shares owned actually by such
shareholder and shares owned constructively by such shareholder pursuant to
Section 318 of the Code.  Under Section 318 of the Code, a shareholder will
be deemed to own stock that is actually or constructively owned by certain
members of his or her family (spouse, children, grandchildren and parents)
and other related parties including, for example, certain entities in which
such shareholder has a direct or indirect interest (including partnerships,
estates, trusts and corporations), as well as shares of stock that such
shareholder (or a related person) has the right to acquire upon exercise of
an option or conversion right.  Section 302(c)(2) of the Code provides
certain exceptions to the family attribution rules for the purpose of
determining whether a complete redemption of a shareholder's interest has
occurred for purposes of Section 302 of the Code.

   First Sterling has received from Counsel an opinion to the effect that
the Merger will be a "reorganization" for federal income tax purposes
under Section 368(a)(1)(A) of the Code, by reason of Section 368(a)(2)(D)
of the Code, and that the other federal income tax consequences of the
Merger are in all material respects as described in this section.  The
opinion is available without charge upon written request to Jon W.
Bilstrom, General Counsel and Secretary, Mercantile Bancorporation Inc.,
P.O. Box 524, St. Louis, Missouri 63166-0524.  Such opinion is subject
to the conditions and assumptions stated therein and relies on various
representations made by MBI, First Sterling and certain shareholders of First
Sterling.  An opinion of counsel, unlike a private letter ruling from the
Service, has no binding effect on the Service. The Service could take a
position contrary to counsel's opinion and, if the matter is litigated, a
court may reach a decision contrary to the opinion. The Service is not
expected to issue a ruling on the tax effects of the Merger, and no such
ruling has been requested.

   THE FOREGOING IS A GENERAL DISCUSSION OF THE MATERIAL FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER AND IS INCLUDED FOR GENERAL INFORMATION ONLY.  THE
FOREGOING DISCUSSION DOES NOT TAKE INTO ACCOUNT THE PARTICULAR FACTS AND
CIRCUMSTANCES OF EACH FIRST STERLING SHAREHOLDER'S TAX STATUS AND ATTRIBUTES.
AS A RESULT, THE FEDERAL INCOME TAX CONSEQUENCES ADDRESSED IN THE FOREGOING
DISCUSSION MAY NOT APPLY TO EACH FIRST STERLING SHAREHOLDER.  IN VIEW OF THE
INDIVIDUAL NATURE OF INCOME TAX CONSEQUENCES, EACH FIRST STERLING SHAREHOLDER
SHOULD CONSULT HIS OR HER OWN TAX ADVISOR REGARDING THE SPECIFIC TAX
CONSEQUENCES OF THE MERGER TO SUCH SHAREHOLDER, INCLUDING THE APPLICATION AND
EFFECT OF FEDERAL, STATE, LOCAL AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS
OF CHANGES IN FEDERAL AND OTHER TAX LAWS.

              RIGHTS OF DISSENTING SHAREHOLDERS OF FIRST STERLING
              ---------------------------------------------------

   Each holder of First Sterling Common Stock has the right to dissent from
the Merger and receive the fair value of such shares of First Sterling Common
Stock in cash if the shareholder follows the procedures set forth in the
Illinois Statute, included as Annex B hereto and the material provisions of
                              -------
which are summarized below.  Pursuant to the Illinois Statute, a holder of
First Sterling Common Stock may dissent and Merger Sub, as the surviving
corporation, will pay to such shareholder the fair value of such
shareholder's shares of First Sterling Common Stock, exclusive of any
appreciation or depreciation in anticipation of the Merger, as of immediately
before the consummation of the Merger if such shareholder (1) files with
First Sterling prior to the vote being taken a written demand for payment for
their shares if the Merger is consummated; and (2) does not vote in favor
                                           ---
thereof.  MBI will include notice of the Effective Date in its letter to all
shareholders of First Sterling notifying them of the procedures to exchange
their shares for those of MBI.  Such letter shall be sent promptly following
the Effective Date.  Within 10 days after the shareholders' vote is effective
or 30 days after the shareholder delivers to First Sterling the written
demand for payment, whichever is later, Merger Sub shall send each
shareholder who has delivered a written demand for payment a statement
setting forth the opinion of Merger Sub as to the estimated fair value of the
shares, First Sterling's latest balance sheet as of the end of a fiscal year
ended not earlier than 16 months before the delivery of the statement,
together with the statement of income for that year and the latest available
interim financial statements, and either a commitment to pay for the shares
of the dissenting shareholder at the estimated fair value thereof upon
transmittal to Merger Sub of the certificate or certificates, or other
evidence of ownership, with respect to the shares.  A VOTE AGAINST THE
MERGER, WHETHER BY PROXY OR IN PERSON, WILL NOT, BY ITSELF, BE REGARDED AS A
WRITTEN DEMAND FOR PAYMENT FOR PURPOSES OF ASSERTING DISSENTERS' RIGHTS.

                                    - 39 -
<PAGE> 42

   Upon consummation of the Merger, Merger Sub shall pay to each dissenter
who transmits to Merger Sub the certificate or other evidence of ownership of
the shares the amount Merger Sub estimates to be the fair value of the
shares, plus accrued interest, accompanied by a written explanation of how
the interest was calculated.  Upon payment of the agreed value, the
dissenting shareholder shall cease to have any interest in such shares or in
First Sterling or MBI.

   If the dissenting shareholder does not agree with the opinion of Merger
Sub as to the estimated fair value of the shares or the amount of interest
due, the dissenting shareholder must, within 30 days from the delivery of
Merger Sub's statement of value, notify Merger Sub in writing, of the
shareholder's estimated fair value and interest due and demand payment for
the difference between the shareholder's estimate of fair value and interest
due and the amount of the payment by Merger Sub.  If, within 60 days from
delivery to Merger Sub of the shareholder notification of estimate of fair
value of shares and interest due, Merger Sub and the dissenting shareholder
have not agreed in writing upon the fair value of the shares and interest
due, Merger Sub shall either pay the difference in value demanded by the
shareholder, with interest, or file a petition in the circuit court of the
county in which either the registered office or the principal office of
Merger Sub is located, requesting the court to determine the fair value of
the shares and interest due.  The "fair value" determined by the court may be
more or less than the amount offered to First Sterling shareholders under the
Merger Agreements.  The judgment shall be payable only upon, and
simultaneously with, the surrender to MBI of the certificate or certificates
representing said shares of First Sterling Common Stock.  Upon the payment of
the judgment, the dissenting shareholder shall cease to have any interest in
such shares or in First Sterling or MBI.

   THE FOREGOING SUMMARY OF THE PROVISIONS REGARDING DISSENTERS' RIGHTS UNDER
THE ILLINOIS STATUTE IS QUALIFIED IN ITS ENTIRETY BY THE COMPLETE TEXT OF THE
ILLINOIS STATUTE WHICH IS ATTACHED HERETO AS ANNEX B.
                                             -------

   First Sterling shareholders who are interested in perfecting dissenters'
rights pursuant to the Illinois Statute in connection with the Merger should
consult with their counsel for advice as to the procedures required to be
followed.

PRO FORMA COMBINED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

   The following unaudited pro forma combined consolidated balance sheet
gives effect to the Merger, and the proposed acquisitions of Conway and Hawkeye
as if each of the mergers were consummated on December 31, 1994.
    

   MBI acquired Ameribanc on April 30, 1992, which acquisition was accounted
for under the purchase method of accounting.  Accordingly, the historical
results of operations of MBI include the results of operations of Ameribanc
from May 1, 1992 forward.  The following pro forma combined consolidated
income statements include the results of operations of Ameribanc from January
1, 1992 through the date of acquisition.

   
   The following pro forma combined consolidated income statements for
the nine months ended September 30, 1995 and 1994 and for the years
ended December 31, 1994, 1993 and 1992 set forth the results of
operations of MBI combined with the results of operations of First
Sterling, Conway and

Hawkeye as if the Merger, and the proposed acquisitions of Conway and Hawkeye
had occurred as of the first day of the period presented.  As stated above,
the pro forma combined consolidated income statements for the year ended
December 31, 1992 include the results of operations of Ameribanc from January
1, 1992 through the date of acquisition.

   The unaudited pro forma combined consolidated financial statements should
be read in conjunction with the accompanying Notes to the Pro Forma Combined
Consolidated Financial Statements and with the historical financial statements
of MBI, First Sterling, Conway, Hawkeye and Ameribanc.  The historical interim
financial information for the nine months ended September 30, 1995 and 1994,
used as a basis for the pro forma combined consolidated financial statements,
include all necessary adjustments, which, in management's opinion, are
necessary to present the data fairly.  These pro forma combined consolidated
financial statements may not be indicative of the results of operations that
actually would have occurred if the completed and proposed acquisitions had
been consummated on the dates assumed above or of the results of operations
that may be achieved in the future.

   Due to the immateriality of the results of operations of Wedge,
AmeriFirst, Southwest, Plains Spirit and Metro to that of MBI, individually
and in the aggregate, the unaudited pro forma combined consolidated financial
statements contained herein do not reflect the completed acquisitions of Wedge,
AmeriFirst, Southwest or Plains Spirit for any period prior to the respective
acquisition dates of such entities or the proposed acquisition of Metro.

                      INFORMATION REGARDING FIRST STERLING
                      ------------------------------------

BUSINESS

  GENERAL.    First Sterling is a bank holding company registered with the
Federal Reserve Board under the BHCA.  First Sterling currently owns all of
the issued and outstanding shares of capital stock of First National Bank of
Sterling-Rock Falls, a national banking association chartered under the laws
of the United States (the "Bank").  As of September 30, 1995, on a
consolidated basis, First Sterling had total assets of $170.0 million, total
deposits of $132.5 million, total loans of $84.3 million and shareholders'
equity of $18.3 million.

  First Sterling is a full service community bank which provides a full
complement of banking services to its customers, primarily individuals and
small businesses in the communities of Sterling, Illinois and Rock Falls,
Illinois.  First Sterling accepts demand, savings and time deposits, makes
commercial, agricultural, consumer and real estate loans and provides trust
and other customary commercial banking services.

  First National Bank of Sterling-Rock Falls was formed by the merger of First
National Bank of Sterling and Rock Falls National Bank on December 9, 1991.
The predecessor of First National Bank of Sterling was granted a charter in
1934 as The National Bank of Sterling and, after changing its name to First
National Bank of Sterling, was acquired by First Sterling Bancorp, Inc. in
1983.  Rock Falls National Bank was chartered in 1945 and was acquired by
First Sterling in 1990.

  COMPETITION.  The activities in which First Sterling engages are highly
competitive and the communities in which it provides services are also served
by other banks and thrifts, as well as small credit unions.  Competition among
these financial institutions is based upon interest rates offered on deposit
accounts, interest rates charged on loans, other credit and service charges,
the convenience of banking facilities and the quality of services rendered.
First Sterling believes it has successfully competed in its marketplace by
providing superior service to its customers and by successfully creating a
market niche in lending to individuals.  However, First Sterling's competitors
may have certain competitive advantages, including affiliations with larger
bank holding companies or less rigorous Federal or state regulation of their
activities, that permit them to more effectively provide some services.
Further, additional competition for depositors' funds may come from a variety
of sources, including United States Government securities, private issuers of
debt obligations, mutual funds and suppliers of other investment alternatives.

  First Sterling's principal executive offices are located at 305 4th Avenue
in Sterling, Illinois (phone: (815) 626-0045) and it has a branch office at
300 First Avenue in Rock Falls.

   
  GENERAL DESCRIPTION OF CAPITAL STOCK.  First Sterling's authorized
capital stock consists of 5,000,000 shares of Common Stock, 3,685,061 shares
of which were issued and outstanding as of the date hereof.  First Sterling
Common Stock was held of record by approximately 37 shareholders as of the
date hereof.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS AS OF AND FOR THE YEARS ENDED DECEMBER 31, 1994, 1993 AND 1992

  The following is a discussion and analysis of the financial condition and
performance of First Sterling and the Bank for the three years ended December
31, 1994, and should be read in conjunction with the consolidated financial
statements and notes thereto.

  OVERVIEW.  First Sterling and its two banking offices are located in
Sterling and Rock Falls, Illinois.  First Sterling is a leading commercial
banking organization in its local market and conducts a full service community
banking and trust business through the Bank.  First Sterling has competed
effectively with a variety of competitors in its market, including affiliates
or branches of much larger bank holding company organizations, a smaller
independent community bank, a successful mutual savings association and credit
unions.  Nonbank competitors, such as mutual funds, also compete for the
Bank's deposit customers.  The Bank has concentrated on long-term customer
relationships and quality service.

  First Sterling has established a long period of continued profitability,
together with an increasing level of capital, despite growing competition in
the financial services industry.

  Total asset and deposit growth are primarily dependent on economic and
population factors in the Bank's local market area.  The Sterling - Rock Falls
area has not experienced significant economic or population growth over the
past few years, as reflected in the relatively stable asset and
deposit/repurchase agreement totals over this period.  Management of First
Sterling considers the Sterling - Rock Falls area to be stable in economic
terms, with noticeable improvement from the recession years of 1991 and 1990.

  Total assets at December 31, 1994 were $163,295,000 compared to $167,513,000
at the prior year end, resulting in a decrease of 2.5%.  Total deposits and
repurchase agreements also decreased modestly by 4.7% from December 31, 1993.
The decrease in total assets and deposits and repurchase agreements followed a
period of several years of stable asset and deposit volumes.

  Primarily due to federal monetary policy, market interest rates rose
substantially during 1994.  For example, the national prime rate was 6% on
January 1, 1994, compared to 8.5% at the end of the year.  Like many other
banking organizations, First Sterling did not raise the interest rates paid on
its deposit products in proportion to the rise in rates on U.S. Treasury
securities and other debt instruments.  In fact, the cost of funds for all of
the Bank's interest-bearing deposits decreased in 1994 as compared to 1993.
Conservative pricing, while helping the net interest margin, contributed to a
modest loss of 2.7% in average interest-bearing deposits in 1994.

  The decrease in average interest-bearing deposits in 1994 was offset by an
increase of $1,377,000, or 7.8%, in average noninterest-bearing demand
deposits.  In addition, the average balance of repurchase agreements increased
$891,000, or 5.6%, in 1994 as compared to the prior year.

  While year end total assets, deposits and repurchase agreements all
decreased somewhat from 1993 levels, average assets actually increased 0.25%
in 1994.

  AVERAGE BALANCES.  The following table sets forth certain information
relating to First Sterling's average consolidated balance sheets and reflects
the yield on average assets and cost of average liabilities for the years
indicated.

   NET INTEREST INCOME.  Net interest income represents the difference
between interest earned on loans, securities and other earnings assets, and
the interest expense on the deposits and other borrowings which fund them.
Net interest income is the principal source of earnings for First Sterling.

   In the preceding table, net interest income is presented on a fully tax
equivalent basis which adjusts the tax exempt status of earnings from certain
securities, primarily obligations of state and local governments.  The table
of average balances, tax equivalent yields and rates should also be referred
to in analyzing the net interest income.

   Changes in interest rates and the mix of interest-earning assets and the
interest-bearing liabilities are prominent factors affecting net interest
income.  Another important factor is the ratio of interest-bearing liabilities
to interest-earning assets, which was 82.8%, 84.6% and 86.5% in 1994, 1993 and
1992, respectively.

   First Sterling's net interest rate spread equals the excess of the fully
tax equivalent yield on earning assets over the rate on interest-bearing
liabilities.  The net yield on average earning assets equals net interest
income divided by average earning assets.  A summary of First Sterling's
interest rate spread, net of yield earning assets and net interest income
follows, presented on a fully tax equivalent basis.

   As explained earlier, interest rates rose sharply in 1994.  In 1993, rates
were relatively stable, as the national prime rate remained at 6% throughout
the entire year.  Rates declined somewhat in 1992, as the national prime rate
declined from 6.5% at January 1 to 6% by about mid-year.  Despite changes in
interest rates, First Sterling managed its pricing and mix of earning assets
and interest-bearing liabilities to maintain a stable interest margin
throughout this three year period.

   The following table sets forth changes in net interest income attributable
to changes in the volume of interest-earning assets and interest-bearing
liabilities compared to changes in interest rates for the periods indicated.

</TABLE>


   Loans, net of the allowance for loan losses, increased by 3.6% during 1994
to $76,711,000.  The largest increase was in commercial and agricultural
loans which increased $6,439,000, or 19.6%.  Most of the new commercial loans
were real estate financings.  The majority of these loans were to owner
occupied businesses with maximum terms of five years at fixed rates.

   Loans to agricultural borrowers were approximately $9,600,000 and
$7,130,000 at December 31, 1994 and 1993, respectively.  The local
agricultural economy generally performed satisfactorily in 1994.

   Installment loans are primarily loans to individuals for automobile
purchases, home improvements and other consumer purposes.  As of December 31,
1994, approximately half of the installment loan portfolio consisted of
indirect automobile paper.  Installment loans continued to decrease during
1994 due to aggressive pricing by competitors and more conservative bank
underwriting practices as compared to earlier years.

   During 1994, the Bank sold most of its student loans, as management
determined that labor and administrative costs of holding and servicing these
loans was no longer an attractive business activity.  Proceeds from the sale
of the student loan portfolio were $3,651,000, including a gain of $40,000.

   CREDIT QUALITY AND THE ALLOWANCE FOR LOAN LOSSES.  As scheduled
below, the trends in nonperforming loans are favorable.  Management of First
Sterling continues to emphasize the early identification of loan related
problems.  Management is not currently aware of any other significant loan,
group of loans or segment of the loan portfolio not included in the table
below as to which there are serious doubts as to the ability of the
borrower(s) to comply with the present loan payment terms.

   When serious doubt exists as to the collectability of a loan, the accrual
of interest is discontinued.  Generally, loans ninety days or more past due
are placed on nonaccrual status, unless they are well secured and in the
process of collection.  The interest on nonaccrual loans which would have
been accrued, as well as the interest collected on such loans, was not
material in 1994 and 1993.

   The allowance for loan losses is maintained at a level considered adequate
to cover possible losses that are currently anticipated based on past loss
experience, general economic conditions, information about specific borrower
situations including their financial position and collateral values and other
factors and estimates which are subject to change over time.

   The Board of Directors and management of First Sterling work together in a
coordinated credit approval and review process.  The approval and review
process is designed to help assure that underwriting standards are maintained
as loans are originated.  The review process is also intended to identify
borrowers who might be experiencing financial difficulties.  Once identified,
potential problem borrowers are closely monitored, and are considered when
establishing specific loan loss allowances or charge-offs.

   Risk codes or ratings are assigned to loans by management to help assess
credit quality.  The Bank has also established an internal loan review
function to help provide ongoing monitoring of credit risk.  The risk code
ratings are used in "watch list" reporting of potential problem credits and
also in establishing allocations of the loan loss allowance to groups of
loans.  Specific allocations of the loan loss allowance are also made for
individual problem borrowers.

   Other factors considered by the Board of Directors and management of First
Sterling in determining the adequacy of the allowance for loan losses each
quarter include changes in loan volume and trends in net charge-offs,
nonaccrual loans, other watch list loans and loan delinquencies.  Local and
national economic conditions are also documented and considered in reviewing
the adequacy of the allowance for loan losses.

   Net loan charge-offs were not significant during 1994 and 1993.

further reflection of the adequacy of the allowance for loan losses, the
quality of the loan portfolio and overall credit administration procedures.

   PROVISION FOR LOAN LOSSES.  The provision for loan losses was $66,000
in 1994 compared to $258,000 and $375,000 in 1993 and 1992, respectively.
Credit quality improved considerably in 1993 and 1994 as compared to 1992.
The table below indicates the positive trends in various measures of credit
quality in the three year period ended December 31, 1994.

   Loan loss provisions decreased during the three years ended December 31,
1994 primarily because of improving credit quality, as indicated above.

   SECURITIES.  On January 1, 1994, First Sterling adopted Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments
in Debt and Equity Securities" which requires classifications of debt
securities as either held-to-maturity, trading or available-for-sale.
Securities classified as available-for-sale are carried at fair value.
Accordingly, certain securities were reclassified as available-for-sale as of
January 1, 1994.  First Sterling has never maintained a trading account.
Prior to 1994, all debt securities were considered held for investment and
were carried at amortized cost.

   United States Treasury and Government Agency fixed rate securities with
average maturities of thirty months or less are generally classified as
available-for-sale.  All mortgage-backed securities and collateralized
mortgage obligations are classified as available-for-sale.  Asset-backed
corporate securities are also generally classified as available-for-sale.

   Securities classified as held-to-maturity are those which First Sterling
has the ability and positive intent to hold until maturity.  Longer term,
fixed rate securities with bullet maturities are generally classified as
held-to-maturity.  In addition, most obligations of states and political
subdivisions and corporate securities (other than those which are
asset-backed) are classified as held-to-maturity.

                                    - 60 -
<PAGE> 63

   Holdings of mortgage-backed securities and collateralized mortgage
obligations are primarily issued by the Federal Home Loan Mortgage
Corporation ("Freddie Mac"), the Federal National Mortgage Association
("Fannie Mae") and the Government National Mortgage Association ("Ginnie
Mae").  Most of the mortgage-backed securities and some of the collateralized
mortgage obligations have adjustable rates.

   The objectives of the securities portfolio are to provide First Sterling
both with a source of liquidity and a maximum return within predetermined
risk limitations.  The securities portfolio is an important tool for First
Sterling's overall interest rate and credit risk management.

   The total carrying value of securities decreased $5,050,000 in 1994.  Of
this decrease, $1,138,000 was due to adjusting the available-for-sale
securities to fair value at December 31, 1994.  The remaining decrease was
primarily due to maturities of U.S. Treasury notes and maturities and
principal repayments of collateralized mortgage obligations that were not
reinvested in securities due to increased loan demand and a modest decrease
in deposits.  The amortized cost of U.S. Treasury notes and collateralized
mortgage obligations decreased 17.8% and 11.7%, respectively, in 1994.

   No debt securities were sold in 1994, 1993 or 1992.  Traditionally, First
Sterling has been a "buy and hold" investor in debt securities.  In 1992, a
mutual fund investment in adjustable rate mortgage-backed securities was
purchased.  This mutual fund investment did not perform as expected and it
was sold in 1994 for a $46,000 loss.

   The following table sets forth the carrying value of First Sterling's
securities portfolio at December 31, 1994 and 1993.

   As of December 31, 1994, First Sterling held no securities of any single
issuer, other than the U.S. Treasury and U.S. government agencies and
corporations (including Freddie Mac, Fannie Mae and Ginnie Mae) that exceeded
10% of shareholders' equity.

   First Sterling holds municipal securities which, although not related, are
considered low risk investments.  Other securities held by First Sterling are
considered to be investment grade.

      DEPOSITS.  As discussed above, there was a modest decrease in total
deposits during 1994.  The primary reasons for the decrease are the
competitive banking environment and the aggressive deposit pricing of the
other local financial institutions.  The decrease in deposit volume in the
periods prior to 1993 was primarily due to corporate clients moving funds to
repurchase agreements.

   SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE.  Securities sold
under agreements to repurchase ("repurchase agreements") have become an
important funding source for the Bank over the past few years.  Management of
the Bank has encouraged major deposit customers to consider repurchase
agreements.  Unlike deposits, repurchase agreements are not subject to FDIC
deposit insurance.  Typical repurchase agreement customers are governmental
entities and commercial businesses.

   The following table sets forth certain information regarding repurchase
agreements for 1994 and 1993.

   CAPITAL RESOURCES.  First Sterling is required to maintain a minimum
ratio of total capital to risk-weighted assets (including certain off-balance
sheet activities, such as standby letters of credit) of 8%.  At least half of
the total capital is required to be "Tier 1 Capital."  Under these
guidelines, First Sterling's Tier 1 Capital consists of shareholders' equity
(exclusive of unrealized gains and losses, net of tax, on securities
available-for-sale) less intangible assets.  First Sterling's total capital
consists of Tier 1 Capital plus the allowance for loan losses.  Risk-based
capital ratios are calculated with the reference to risk-weighted assets
including certain off-balance sheet exposures.

   In addition to the risk-based capital requirements, the Federal Reserve
Board requires a minimum leverage ratio (Tier 1 Capital to total assets) of
3%, provided that all but the highest rated bank holding companies which are
not experiencing or anticipating significant growth are expected to maintain
a ratio of 1% to 2% above the stated minimum.

</TABLE>

   NONINTEREST INCOME.  Noninterest income includes service charges on
deposit accounts, security gains and losses, trust fees and other commissions
and fees.  Total noninterest income was $916,000, $847,000 and $960,000 in
1994, 1993 and 1992, respectively.  Most of the increase in 1994, after
adjusting for security gains and losses, was due to increased deposit fee
income and a one time gain of $40,000 from the sale of a majority of the
Bank's student loan portfolio.  The decrease in 1993 was primarily due to
lower levels of deposit fee income, as more accounts maintained sufficient
balances to offset service charges.

   NONINTEREST EXPENSE.  Noninterest expense includes salaries and
employee benefits, occupancy and equipment expense, and other operating
expenses.  Total noninterest expenses decreased $511,000, or 9.1%, in 1994
which followed a $622,000, or 12.4%, increase in 1993.

   Salaries and benefits account for almost half of total noninterest
expenses.  These payroll costs decreased 10% in 1994 following a 10.6%
increase in 1993.  These fluctuations are primarily due to a compensation
payment in 1993 to two executive officers of First Sterling who had served
without pay and spent a considerable amount of time over the previous ten
years on First Sterling matters.  Without the special payment to these two
executive officers, salary and benefits expense would have decreased 4.7% in
1993 as compared to 1992, and the 1994 and 1993 expense amounts would have
been virtually the same.

   In the fourth quarter of 1991, First Sterling merged the former Rock Falls
National Bank and First National Bank of Sterling to form First National Bank
of Sterling-Rock Falls.  Particularly since the merger of the two banks,
management has sought to achieve greater efficiencies and economies of scale.
As a result, the number of full-time equivalent employees of the Bank has
decreased from 85 at January 1, 1992 to 72 at December 31, 1994.  This
reduction in force has helped control payroll related expenses.

   Data processing expense increased $258,000 in 1994, primarily due to one
time conversion costs of $266,000 associated with switching to a new data
processing servicer which were directly expensed.

   Environmental expense in 1993 was $356,000, as compared to zero in 1994
and 1992.  The expense in 1993 primarily represents consulting fees to study
a matter discovered in 1993, as well as a $250,000 expense accrual to provide
for future remediation costs.  Management has concluded that any additional
environmental expenses will not be material to First Sterling's financial
position or results of operations.

   Professional fees in 1993 were greater than normal because of costs
incurred regarding the possible merger of First Sterling into a larger bank
holding company.  Although these merger negotiations terminated in 1993,
First Sterling incurred costs related to services provided by legal counsel
and accountants.

                                    - 64 -
<PAGE> 67

   Except for the effects of additional executive compensation, environmental
expense and higher professional fees in 1993, as well as the data processing
conversion costs in 1994, First Sterling's total noninterest expense in 1994
and 1993 was less than the amount incurred in 1992.

   INCOME TAXES.  Income tax expense was $592,000, $366,000 and $457,000 in
1994, 1993 and 1992, respectively.  The primary reasons for the expense
fluctuations during this period were changes in pretax income.

   First Sterling reduces federal income tax expense through investments in
tax exempt securities.  Historically, First Sterling has earned a higher
fully tax equivalent yield on tax exempt investments than on taxable
securities.  The presence of the alternative minimum tax effectively limits
First Sterling's tax exempt investments to certain desired levels.

   In 1993, First Sterling invested $343,000 in a low income housing project.
Federal income tax credits from this investment resulted in tax benefits of
$38,000 and $15,000 in 1994 and 1993, respectively.

   Beginning in 1993, First Sterling adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109").
The adoption of SFAS 109 changed First Sterling's method of accounting for
income taxes from the deferred method (Accounting Principles Board Opinion
No. 11) to an asset and liability approach.  The asset and liability approach
requires the recognition of deferred tax liabilities and assets for the
expected future tax consequences of temporary differences between the
carrying amounts and the tax bases of asset and liabilities.  The cumulative
effect of this change was $202,000 and primarily represents the impact of
adjusting deferred taxes to reflect current tax rates and recognizing
alternative minimum tax credit carryforwards as deferred tax assets.

   NET INCOME.  Net income increased $375,000, or 25.4%, in 1994.  The
principal reasons for increased earnings in 1994 were the reduced provision
for loan losses, higher noninterest income and a 9.1% reduction in
noninterest expense.

   Net income in 1993 decreased $72,000, or 4.6%, from 1992, despite a
3.9% increase in net interest income.  Reduced earnings were due to the
increase of $622,000, or 12.4%, in noninterest expense and a decrease of
$111,000, or 24%, in service charges on deposits.  These items more than
offset improved net interest income after the provision for loan losses and
the one-time $202,000 tax benefit from the adoption of SFAS 109.

   LIQUIDITY AND INTEREST RATE SENSITIVITY ANALYSIS.  The primary
functions of asset/liability management are to assure adequate liquidity and
maintain an appropriate balance between interest sensitive earning assets and
interest-bearing liabilities.

   The matching of assets and liabilities may be analyzed by examining the
extent to which such assets and liabilities are "interest rate sensitive" and
by monitoring a financial institution's interest rate sensitivity "gap."  An
asset or liability is said to be interest rate sensitive within a specific
time period if it will mature or reprice within that time period.  The
interest rate sensitivity gap is defined as the difference between the amount
of interest-earning assets maturing or repricing within a specific time
period and the amount of interest-bearing liabilities maturing or repricing
within that time period.  A gap is considered positive when the amount of
interest rate sensitive assets exceeds the amount of interest rate sensitive
liabilities.

                                    - 65 -
<PAGE> 68

   A gap is considered negative when the amount of interest rate sensitive
liabilities exceeds the amount of interest rate sensitive assets.  During a
period of rising interest rates, a negative gap would tend to adversely
affect net interest income while a positive gap would tend to result in an
increase in net interest income.  During a period of falling interest rates,
a negative gap would tend to result in an increase in net interest income
while a positive gap would tend to adversely affect net interest income.
First Sterling's gap position is illustrated in a table below.

   Liquidity management involves the ability to meet the cash flow
requirements of customers who may be either depositors wanting to withdraw
funds or borrowers knowing that sufficient funds will be available to meet
their credit needs.

   In addition to federal funds and interest-bearing deposits in banks,
marketable securities, particularly those of shorter maturities, are a
principal source of asset liquidity.  Most of these securities are now
designated as available-for-sale.  Securities available-for-sale or
held-to-maturity which mature in one year or less approximated $14,312,000 at
December 31, 1994, representing 19.4% of the total securities portfolio.

   Rate sensitivity varies with different types of interest-earning assets
and interest-bearing liabilities.  Federal funds on which the rate varies
daily and loans tied to the prime rate differ considerably from long-term
securities and fixed rate loans.  Time deposits over $100,000 are more rate
sensitive than savings accounts.  Management of the Bank has portrayed
savings accounts as immediately repriceable, because of management's ability
to change the savings interest rate.

   With a significant percentage of First Sterling's loan portfolio floating
with the prime rate or repriceable within 30 days, there is an immediate
effect on interest income when rates rise or fall, while interest expense
changes more slowly as certificates of deposit mature.  In addition, the
interest margin on low cost core deposits is increased in a period of rising
rates, as experienced in 1994 with the increase in the prime rate.

   As the interest rate sensitivity table shows, First Sterling is liability
sensitive through the one year time horizon ending December 31, 1995.

   CASH FLOWS.  As shown in the consolidated statements of cash flows for
the three years ended December 31, 1994, First Sterling's cash flows from
operations exceeded net income each year.  Cash flows from operating
activities exceeded accrual basis net income by $712,000, $1,739,000 and
$427,000 in 1994, 1993 and 1992, respectively.  Management expects ongoing
operating activities to continue to be a primary source of cash flow for
First Sterling.

   First Sterling has experienced a relatively stable level of deposits and
repurchase agreements over the past several years, which has helped maintain
an adequate level of cash for First Sterling's activities.  While competition
for deposit and repurchase agreement customers is expected to remain keen and
future growth cannot be predicted with any certainty, First Sterling plans to
continue to actively seek profitable new deposit and repurchase agreement
business.

   The increase in loans and decrease in deposits in 1994 was funded
primarily through:  a $2,800,000 decrease in federal funds sold and a
$2,100,000 increase in federal funds purchased; cash


                                    - 67 -
<PAGE> 70
flows from operations; proceeds from security maturities, calls and paydowns
which exceeded the purchases of new securities by nearly $4,000,000; the sale
of a mutual fund investment; and $3,651,000 in proceeds from the sale of the
Bank's student loan portfolio.

   Loan growth and an increase in First Sterling's securities portfolio in
1993 were funded primarily through cash flows from operations and a decrease
of $5,964,000 in cash and cash equivalents.

   In 1992, net security purchases of approximately $8,300,000 were funded
primarily by a net decrease in loans.

   To insure the ability to meet its funding needs, including any unexpected
strain on liquidity, First Sterling has a $6,500,000 federal funds line of
credit from two independent banks.  In addition, First Sterling also has the
ability to borrow funds, if necessary, directly from the Federal Reserve
Bank.

   First Sterling has no notes payable or similar debt on its balance sheet.
The lack of a debt service requirement allows First Sterling to use its funds
for other operating purposes.

   Equity capital is in excess of regulatory requirements, as determined on
both risk-based and leverage ratio criteria.  Cash dividends have been a
relatively modest percentage of net income, beginning with 10% in 1993 and
increasing to 32% in 1994.  The Merger Agreement also now limits dividends to
$.04 per share per quarter.

   There are no planned capital outlays which would be a significant burden
on First Sterling's cash flows.

   RECENT ACCOUNTING PRONOUNCEMENTS.  Statements of Financial
Accounting Standards No. 114 and No. 118 were adopted at January 1, 1995.
Under these standards, loans considered to be impaired are reduced to the
present value of expected future cash flows or to the fair value of
collateral, by allocating a portion of the allowance for loan losses to such
loans.  If these allocations cause the allowance for losses to require an
increase, such increase is reported as bad debt expense.  The effect of
adopting this standard is not considered material to First Sterling due to
the relatively low amount of nonperforming loans at December 31, 1994.  First
Sterling's allowance for loan losses is considered adequate after considering
the effect of SFAS 114 and 118.

   In May 1995, the Financial Accounting Standards Board issued SFAS 122,
"Accounting for Mortgage Servicing Rights."  Adoption of SFAS 122 applies
prospectively, in fiscal years beginning after December 15, 1995, to
transactions in which a mortgage banking enterprise sells or securitizes
mortgage loans with servicing rights retained.  SFAS 122 also requires
impairment evaluations of all amounts capitalized as mortgage servicing
rights.  SFAS 122 is not expected to have any material effect on First
Sterling, since First Sterling does not sell mortgage loans in the secondary
market or service mortgage loans for other investors.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS AS OF AND FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1995 AND 1994

   The following discussion focuses on the consolidated financial condition
of First Sterling at September 30, 1995, and the consolidated results of
operations for the nine months ended September 30, 1995, compared to the same
period in 1994.  This discussion should be read in conjunction with the
interim condensed consolidated financial statements and notes thereto.


                                    - 68 -
<PAGE> 71

   FINANCIAL CONDITION.  First Sterling's consolidated total assets
increased $6,707,000, or 4.1%, from December 31, 1994 to September 30, 1995.
Total assets were $170,002,000 at September 30, 1995, which is at or near a
record high level for First Sterling.  Average assets for the nine-month
periods ended September 30, 1995 and 1994 were $165,540,000 and $165,439,000,
respectively, virtually the same in each period.

   The growth in assets in 1995 was largely due to an increase of $5,259,000,
or 4.1%, in total deposits and an increase of $1,651,000, or 10.3%, in
securities sold under repurchase agreements.  Noninterest-bearing demand
deposits at September 30, 1995 were approximately the same as at the
beginning of the year.  The deposit growth in 1995 occurred primarily in time
certificates of deposits, where the Bank realized increased volumes from
retail, commercial and governmental customers.  The Bank ran special promotions
of thirteen- and twenty-month certificates of deposit in 1995, which
contributed to growth in this area.

   The total carrying value of securities was $72,914,000 at September 30,
1995, which is only $141,000 more than the carrying value at December 31,
1994.  There were no substantial changes in the mix of the securities
portfolio at September 30, 1995, as compared to the beginning of the year.
The maturity tables in Note 2 to First Sterling's consolidated financial
statements indicate that maturities were shortened somewhat by September 30,
1995, compared to the beginning of the year, as a greater portion of the
securities are now due within one year.

   In 1995, fair values of securities improved relative to amortized cost.
Unrealized losses on securities available-for-sale were $50,000 at September
30, 1995, compared to $1,138,000 at December 31, 1994.  Securities
held-to-maturity had unrealized gains of $405,000 at September 30, 1995,
compared to unrealized losses of $253,000 at the beginning of the year.
Improvement in fair values was largely due to lower market interest rates at
September 30, 1995, as well as shorter maturities in First Sterling's
securities portfolio.

   Most of the growth in assets was in the loan portfolio.  As of September
30, 1995, total loans had increased approximately $7.5 million, or 9.6%,
since the beginning of the year.  Management has more aggressively sought
loan growth in 1995.  Marketing and business development efforts have helped
to increase volume in residential and commercial real estate loans,
commercial and agricultural credits, and installment lending.  Real estate
mortgage loans have increased $1,485,000, or 8.5%, from December 31, 1994.
Commercial and agricultural loans also increased significantly, by
$3,479,000, or 8.9%.  Largely through increased efforts in obtaining indirect
loans from automobile dealers, installment loans were up $2,816,000, or
14.7%, from the beginning of the year.

   Shareholders' equity increased $1,585,000 during the nine months ended
September 30, 1995.  The increase is a result of net income of $1,309,000,
unrealized gains on securities available-for-sale, net of deferred tax, of
$718,000, and the payment of $442,000 in dividends.

   First Sterling's capital levels at September 30, 1995 remained well above
amounts required by banking regulators.  The leverage ratio at September 30,
1995 was 10.65%, compared to required levels ranging from 3% to 5%.

   NET INTEREST INCOME.  Net interest income, the difference between
interest income on earning assets and interest expense on interest-bearing
liabilities, decreased $210,000, or 4.2%, for the nine months ended September
30, 1995, compared to the same period in 1994.  While interest income
increased 9.4%, interest expense increased 30.4%.  The Bank is paying
significantly more for its deposits and repurchase agreements in 1995 as
compared to 1994.


                                    - 69 -
<PAGE> 72

   The growth in interest-bearing liabilities has been in higher cost time
certificates of deposit and repurchase agreements.  While the Bank did not
increase deposit and repurchase agreement rates in 1994 as fast as the prime
rate rose, it should be noted that rates at January 1, 1995 were
significantly higher than at the beginning of 1994.  Thus, the lag time in
raising deposit and repurchase agreement rates was mostly gone by 1995.

   Due to competitive pressures, the Bank raised deposit and repurchase
agreement rates in 1995.  On the asset side, the national prime lending rate
was 8.5% as of January 1, 1995, rose as high as 9%, and was at 8.75% at
September 30, 1995.  Longer term rates were generally lower at September 30,
1995, compared to the beginning of the year.

   The following table indicates changes in earning asset yields and rates on
interest-bearing liabilities for the nine months ended September 30, 1995 and
1994.

   PROVISION FOR LOAN LOSSES.  The provision for loan losses was
$162,000 for the nine months ended September 30, 1995, compared to $66,000
for the same period in 1994.  While nonaccrual loans have declined slightly
from December 31, 1994, the higher loan loss provision in 1995 is largely due
to loan growth and an increase in loans ninety days past due which are still
accruing.  The allowance for loan losses was 417% of nonperforming loans at
September 30, 1995, compared to 519% at September 30, 1994 and 406% at
December 31, 1994.  Based upon its analysis, management believes the
allowance for loan losses was adequate at September 30, 1995 to cover future
possible loan losses.

   NONINTEREST INCOME.  Noninterest income was $656,000 for the nine
months ended September 30, 1995, compared to $669,000 for the same period in
1994.  Securities losses were $1,000 in 1995 and $44,000 in 1994.  The 1994
securities losses include a $46,000 loss on the sale of a mutual fund
investment.

   Service charges on deposits decreased $47,000, or 16.3%, in 1995.
Customers continued to use higher balances to avoid or reduce service
charges.  In addition, the number of customers subject to frequent overdraft
and non-sufficient funds charges has decreased in 1995.  Noninterest income
in 1994 also includes a $40,000 gain on the sale of student loans.

   NONINTEREST EXPENSE.  Total noninterest expense was $3,621,000 as of
September 30, 1995, compared to $3,907,000 for the same period in 1994.  The
primary reasons for this 7.3% decrease are discussed below.

   In the second quarter of 1995, the Bank Insurance Fund ("BIF") reached its
designated reserve ratio of 1.25% of insured deposits.  As a result, the FDIC
reduced risk-based BIF premium rates from a range of $.23 to $.31 to a range
of $.04 to $.31 for every $100 of deposits.  Since the Bank is subject to the
lowest BIF premium rate, the rate reduction resulted in a cost reduction of
$86,000, or 38.9%, for the nine months ended September 30, 1995 compared to
the same period last year.


                                    - 70 -
<PAGE> 73

   Data processing conversion costs of $266,000 were incurred and expensed in
the nine months ended September 30, 1994.  Without these nonrecurring
charges, data processing expense would have been $241,000 in 1994 as compared
to $206,000 in the same period of 1995.

   Noninterest expenses classified as "other expenses" on the consolidated
statements of income were $1,000,000 for the nine months ended September 30,
1995 compared to $786,000 for the prior year period.  Reasons for the 27%
increase include a $66,000 write off of repossessed collateral in 1995.
Professional fees were $55,000 higher in 1995, as First Sterling engaged
firms to:  help with strategic and capital planning at the holding company
level; consult with First Sterling regarding a proposed merger transaction;
prepare a marketing study; and perform certain procedures which were
previously done by the Bank's internal auditor.  Several other expense
categories increased somewhat during 1995, including marketing, supplies and
postage, which in part reflect greater business development efforts.

   Salaries and benefits, occupancy and furniture and equipment expenses were
slightly less as of September 30, 1995 as compared to the prior year period.

   Amortization expense related to intangible assets decreased $66,000 for
the nine months ended September 30, 1995.  The excess purchase price
resulting from First Sterling's acquisition of First National Bank of
Sterling was fully amortized by March 31, 1995.  Amortization of the core
deposit intangible asset was less in 1995 than in 1994 because First Sterling
is using an accelerated method to amortize this asset over ten years.

   NET INCOME.  Income before income taxes decreased by $33,000 in the 1995
period compared to 1994.  However, income tax expense decreased $55,000 in
1995, primarily due to less pre-tax income, increased tax exempt interest
income and less nondeductible amortization expense.

   As a result of the items discussed above, net income increased $22,000, or
1.7%, to $1,309,000 for the nine months ended September 30, 1995.  The return
on average assets increased slightly in 1995 to 1.05% as compared to 1.04% in
the prior year period.

                     INFORMATION REGARDING MBI STOCK
                     -------------------------------

DESCRIPTION OF MBI COMMON STOCK AND ATTACHED PREFERRED SHARE PURCHASE RIGHTS

  GENERAL.  MBI has authorized 5,000,000 shares of MBI Preferred Stock, no
par value, and 100,000,000 shares of MBI Common Stock, $5.00 par value.  At
September 30, 1995, MBI had 14,806 shares of MBI Preferred Stock issued and
outstanding and 55,333,878 shares of MBI Common Stock outstanding.  Under
Missouri law, MBI's Board of Directors may generally approve the issuance of
authorized shares of Preferred Stock and Common Stock without shareholder
approval.

   MBI's Board of Directors is also authorized to fix the number of shares
and determine the designation of any series of Preferred Stock and to
determine or alter the rights, preferences, privileges and restrictions
granted to or imposed upon any series of MBI Preferred Stock.  Except for the
designation and reservation of Series A Junior Participating Preferred Stock
pursuant to MBI's Preferred Share Purchase Rights Plan described below, and,
in connection with the acquisition of TCB on May 1, 1995, the designation and
issuance of (i) 5,306 shares of Series B-1 Preferred Stock and (ii) 9,500
shares of Series B-2 Preferred Stock, MBI's Board of Directors has not acted
to designate or issue any shares of MBI Preferred Stock.

   The existence of a substantial number of unissued and unreserved shares of
MBI Common Stock and undesignated shares of MBI Preferred Stock may enable
the Board of Directors to issue shares to such persons and in such manner as
may be deemed to have an anti-takeover effect.

   The following summary of the terms of MBI's capital stock does not purport
to be complete and is qualified in its entirety by reference to the
applicable provisions of MBI's Restated Articles of Incorporation and By-Laws
and Missouri law.

  DIVIDENDS.  The holders of MBI Common Stock are entitled to share ratably
in dividends when, as and if declared by the Board of Directors from funds
legally available therefor, after full cumulative dividends have been paid or
declared, and funds sufficient for the payment thereof set apart, on all
series of MBI Preferred Stock ranking superior as to dividends to MBI Common
Stock.

   The Board of Directors of MBI intends to maintain its present policy of
paying quarterly cash dividends on MBI Common Stock, when justified by the
financial condition of MBI and its subsidiaries.  The declaration and amount
of future dividends will depend on circumstances existing at the time,
including MBI's earnings, financial condition and capital requirements as
well as regulatory limitations, note and indenture provisions and such other
factors as the Board of Directors may deem relevant.  Because MBI is a
holding company, its ability to pay dividends is dependent upon receipt of
dividends and/or management fees from its subsidiary banks.  The payment of
dividends to MBI by subsidiary banks is subject to extensive regulation by
various state and federal regulatory agencies.  See "SUPERVISION AND
REGULATION."

  VOTING RIGHTS.  Each holder of MBI Common Stock has one vote for each share
held on matters presented for consideration by the shareholders, except that,
in the election of directors, each shareholder has cumulative voting rights
which entitle such shareholder to the number of votes which equals the number
of shares held by the shareholder multiplied by the number of directors to be
elected.  All such votes may be cast for one candidate for election as a
director or may be distributed among two or more candidates.


                                    - 74 -
<PAGE> 77

  PREEMPTIVE RIGHTS.  The holders of MBI Common Stock have no preemptive
right to acquire any additional unissued shares or treasury shares of MBI.

  LIQUIDATION RIGHTS.  In the event of liquidation, dissolution or winding up
of MBI, whether voluntary or involuntary, the holders of MBI Common Stock
will be entitled to share ratably in any of its assets or funds that are
available for distribution to its shareholders after the satisfaction of its
liabilities (or after adequate provision is made therefor) and after
preferences on any outstanding MBI Preferred Stock.

  ASSESSMENT AND REDEMPTION.  Shares of MBI Common Stock are and will be,
when issued, fully paid and nonassessable.  Such shares do not have any
redemption provisions.

  PREFERRED SHARE PURCHASE RIGHTS PLAN.  One preferred share purchase right
(a "Right") is attached to each share of MBI Common Stock.  The Rights trade
automatically with shares of MBI Common Stock, and become exercisable and
will trade separately from the MBI Common Stock on the tenth day after public
announcement that a person or group has acquired, or has the right to
acquire, beneficial ownership of 20% or more of the outstanding shares of MBI
Common Stock, or upon commencement or announcement of intent to make a tender
offer for 20% or more of the outstanding shares of MBI Common Stock, in
either case without prior written consent of the Board.  When exercisable,
each Right will entitle the holder to buy 1/100 of a share of MBI Series A
Junior Participating Preferred Stock at an exercise price of $100 per Right.
In the event a person or group acquires beneficial ownership of 20% or more
of MBI Common Stock, holders of Rights (other than the acquiring person or
group) may purchase MBI Common Stock having a market value of twice the then
current exercise price of each Right.  If MBI is acquired by any person or
group after the Rights become exercisable, each Right will entitle its holder
to purchase stock of the acquiring company having a market value of twice the
current exercise price of each Right.  The Rights are designed to protect the
interests of MBI and its shareholders against coercive takeover tactics.  The
purpose of the Rights is to encourage potential acquirors to negotiate with
MBI's Board of Directors prior to attempting a takeover and to give the Board
leverage in negotiating on behalf of all shareholders the terms of any
proposed takeover.  The Rights may deter certain takeover proposals.  The
Rights, which can be redeemed by MBI's Board of Directors in certain
circumstances, expire by their terms on June 3, 1998.

  CLASSIFICATION OF BOARD OF DIRECTORS.  The Board of Directors of MBI is
divided into three classes, and  the directors are elected by classes to
three-year terms, so that one of the three classes of the directors of MBI
will be elected at each annual meeting of the shareholders.  While this
provision promotes stability and continuity of the Board of Directors,
classification of the Board of Directors may also have the effect of
decreasing the number of directors that could otherwise be elected at each
annual meeting of shareholders by a person who obtains a controlling interest
in the MBI Common Stock and thereby could impede a change in control of MBI.
Because fewer directors will be elected at each annual meeting, such
classification also will reduce the effectiveness of cumulative voting as a
means of establishing or increasing minority representation on the Board of
Directors.

  OTHER MATTERS.  MBI's Restated Articles of Incorporation and By-Laws also
contain provisions which:  (i) require the affirmative vote of holders of at
least 75% of the voting power of all of the shares of outstanding capital
stock of MBI entitled to vote in the election of directors to remove a
director or directors without cause; (ii) require the affirmative vote of the
holders of at least 75% of the voting power of all shares of the outstanding
capital stock of MBI to approve certain "business combinations" with
"interested parties" unless at least two-thirds of the Board of Directors
first approves such business combinations; and (iii) require an affirmative
vote of at least 75% of the voting power of all shares of the outstanding
capital stock of MBI for the amendment, alteration, change or repeal of any


                                    - 75 -
<PAGE> 78

of the above provisions unless at least two-thirds of the Board of Directors
first approves such an amendment, alteration, change or repeal.  Such
provisions may be deemed to have an anti-takeover effect.

RESTRICTIONS ON RESALE OF MBI STOCK BY AFFILIATES

   Under Rule 145 of the Securities Act of 1933 (the "Securities Act"),
certain persons who receive MBI Common Stock pursuant to the Merger and who
are deemed to be "affiliates" of First Sterling will be limited in their
right to resell the stock so received.  The term "affiliate" is defined to
include any person who, directly or indirectly, controls, or is controlled
by, or is under common control with First Sterling at the time the Merger is
submitted to a vote of the shareholders of First Sterling.  Each affiliate of
First Sterling (generally any director or executive officer or shareholder of
First Sterling who beneficially owns a substantial number of outstanding
shares of First Sterling Common Stock) who desires to resell the MBI Common
Stock received in the Merger must sell such stock either pursuant to an
effective registration statement or in accordance with an applicable
exemption, such as the applicable provisions of Rule 145(d) under the
Securities Act.

   Rule 145(d) provides that persons deemed to be affiliates may resell their
stock received in the Merger pursuant to certain of the requirements of Rule
144 under the Securities Act if such stock is sold within the first two years
after the receipt thereof.  After two years if such person is not an
affiliate of MBI and if MBI is current with respect to its required public
filings, a former affiliate of First Sterling may resell the stock received
in the Merger without limitation.  After three years from the issuance of the
stock, if such person is not an affiliate of MBI at the time of sale and for
at least three months prior to such sale, such person may resell such stock,
without limitation, regardless of the status of MBI's required public
filings.  The shares of MBI Common Stock to be received by affiliates of
First Sterling in the Merger will be legended as to the restrictions imposed
upon resale of such stock.

   First Sterling has agreed to provide MBI with a list of those persons who
may be deemed to be affiliates at the time of the Special Meeting.  First
Sterling has agreed to use all reasonable efforts to cause each such person
to deliver to MBI prior to the Effective Time a written agreement to the
effect that no sale will be made of any shares of MBI Common Stock received
in the Merger by an affiliate of MBI except in accordance with the Securities
Act and until such time as MBI shall first publish the financial results of
at least 30 days of post-merger combined operations of First Sterling and
MBI.  The certificates of MBI Common Stock issued to affiliates of First
Sterling in the Merger may contain an appropriate restrictive legend, and
appropriate stop transfer orders may be given to the transfer agent for such
certificates.

COMPARISON OF THE RIGHTS OF SHAREHOLDERS OF MBI AND FIRST STERLING

   MBI is incorporated under the laws of the State of Missouri, while First
Sterling is incorporated under the laws of the State of Illinois.  The rights
of the shareholders of MBI are governed by MBI's Restated Articles of
Incorporation and By-Laws and the Missouri Act.  The rights of First Sterling
shareholders are governed by First Sterling's Articles of Incorporation and
By-Laws and by the Illinois Business Corporation Act of 1983, as amended (the
"Illinois Act").  The rights of First Sterling shareholders who receive
shares of MBI Common Stock in the Merger will thereafter be governed by MBI's
Restated Articles of Incorporation and By-Laws and by the Missouri Act.  The
material rights of such shareholders, and, where applicable, the differences
between the rights of MBI shareholders and First Sterling shareholders, are
summarized below.

                                    - 76 -
<PAGE> 79
  PREFERRED SHARE PURCHASE RIGHTS PLAN.  As described above under "-
Preferred Share Purchase Rights Plan," MBI Common Stock has attached Rights,
which may deter certain takeover proposals.  First Sterling does not have a
rights plan.

  SUPERMAJORITY PROVISIONS.  MBI's Restated Articles of Incorporation and
MBI's By-Laws contain provisions requiring a supermajority vote of the
shareholders of MBI to approve certain proposals.  Under both MBI's Restated
Articles and By-Laws, removal by the shareholders of the entire Board of
Directors or any individual director from office without cause requires the
affirmative vote of not less than 75% of the total votes entitled to be voted
at a meeting of shareholders called for the election of directors.  Amendment
by the shareholders of MBI's Restated Articles or By-Laws relating to (i) the
number or qualification of directors; (ii) the classification of the Board of
Directors; (iii) the filling of vacancies on the Board of Directors; or (iv)
the removal of directors, requires the affirmative vote of not less than 75%
of the total votes of MBI's then outstanding shares of capital stock entitled
to vote, voting together as a single class, unless such amendment has
previously been expressly approved by at least two-thirds of the Board of
Directors.  The Restated Articles of MBI additionally provide that, in
addition to any shareholder vote required under the Missouri Act, the
affirmative vote of the holders of not less than 75% of the total votes to
which all of the then outstanding shares of capital stock of MBI are
entitled, voting together as a single class (the "Voting Stock"), shall be
required for the approval of any Business Combination.  A "Business
Combination" is defined generally to include sales, exchanges, leases,
transfers or other dispositions of assets, mergers or consolidations,
issuances of securities, liquidations or dissolutions of MBI,
reclassifications of securities or recapitalizations of MBI, involving MBI on
the one hand, and an Interested Shareholder or an affiliate of an Interested
Shareholder on the other hand.  An "Interested Shareholder" is defined
generally to include any person, firm, corporation or other entity which is
the beneficial owner of 5% or more of the voting power of the outstanding
Voting Stock.  If, however, at least two-thirds of the Board of Directors of
MBI approve the Business Combination, such Business Combination shall require
only the vote of shareholders as provided by Missouri law or otherwise.  The
amendment of the provisions of MBI's Restated Articles relating to the
approval of Business Combinations requires the affirmative vote of the
holders of at least 75% of the Voting Stock unless such amendment has
previously been approved by at least two-thirds of the Board of Directors.

   To the extent that a potential acquiror's strategy depends on the passage
of proposals which require a supermajority vote of MBI's shareholders, such
provisions requiring a supermajority vote may have the effect of discouraging
takeover attempts that do not have Board approval by making passage of such
proposals more difficult.  Neither First Sterling's Articles of Incorporation
nor First Sterling's By-Laws require a supermajority vote of shareholders
with respect to any item.

  VOTING FOR DIRECTORS.  MBI's By-Laws provide for cumulative voting in the
election of directors.  Cumulative voting entitles each shareholder to cast
an aggregate number of votes equal to the number of voting shares held,
multiplied by the number of directors to be elected.  Each shareholder may
cast all such votes for one nominee or distribute them among two or more
nominees, thus permitting holders of less than a majority of the outstanding
shares of voting stock to achieve board representation.  Neither First
Sterling's Articles of Incorporation or By-Laws provide for cumulative
voting.

  CLASSIFIED BOARD.  As described under "- Classification of Board of
Directors," the Board of Directors of MBI is divided into three classes of
directors, with each class being elected to a staggered three-year term.  By
reducing the number of directors to be elected in any given year, the
existence of a classified Board diminishes the benefits of the cumulative
voting rights to minority shareholders.  First Sterling does not have a
classified Board of Directors.

  ANTI-TAKEOVER STATUTES.  The Missouri Act contains certain provisions
applicable to Missouri corporations such as MBI which may be deemed to have
an anti-takeover effect.  Such provisions include Missouri's business
combination statute and the control share acquisition statute.

   The Missouri business combination statute protects domestic corporations
after hostile takeovers by prohibiting certain transactions once an acquiror
has gained control.  The statute restricts certain "Business Combinations"
between a corporation and an "Interested Shareholder" or affiliates of the
Interested Shareholder for a period of five years unless certain conditions
are met.  A "Business Combination" includes a merger or consolidation,
certain sales, leases, exchanges, pledges and similar dispositions of
corporate assets or stock and certain reclassifications and
recapitalizations.  An "Interested Shareholder" includes any person or entity
which beneficially owns or controls 20% or more of the outstanding voting
shares of the corporation.

   During the initial five-year restricted period, no Business Combination
may occur unless such Business Combination or the transaction in which an
Interested Shareholder becomes "interested" (the "Acquisition Transaction")
was approved by the board of directors of the corporation on or before the
date of the Acquisition Transaction.  Business Combinations may occur after
the five-year period following the Acquisition Transaction only if: (i) prior
to the stock acquisition by the Interested Shareholder, the board of
directors approves the transaction in which the Interested Shareholder became
an Interested Shareholder or approves the Business Combination in question;
(ii) the holders of a majority of the outstanding voting stock, other than
stock owned by the Interested Shareholder, approve the Business Combination;
or (iii) the Business Combination satisfies certain detailed fairness and
procedural requirements.

   The Missouri Act exempts from its provisions: (i) corporations not having
a class of voting stock registered under Section 12 of the Exchange Act; (ii)
corporations which adopt provisions in their articles of incorporation or
bylaws expressly electing not to be covered by the statute; and (iii) certain
circumstances in which a shareholder inadvertently becomes an Interested
Shareholder.  MBI's Restated Articles of Incorporation and By-Laws do not
contain an election to "opt out" of the Missouri business combination
statute.

   The Missouri Act also contains a "Control Share Acquisition Statute" which
provides that an "Acquiring Person" who after any acquisition of shares of a
publicly traded corporation has the voting power, when added to all shares of
the same corporation previously owned or controlled by the Acquiring Person,
to exercise or direct the exercise of:  (i) 20% but less than 33 1/3%, (ii)
33 1/3% or more but less than a majority or (iii) a majority, of the voting
power of outstanding stock of such corporation, must obtain shareholder
approval for the purchase of the "Control Shares."  If approval is not given,
the Acquiring Person's shares lose the right to vote.  The statute prohibits
an Acquiring Person from voting its shares unless certain disclosure
requirements are met and the retention or restoration of voting rights is
approved by both: (i) a majority of the outstanding voting stock, and (ii) a
majority of the outstanding voting stock after exclusion of "Interested
Shares."  Interested Shares are defined as shares owned by the Acquiring
Person, by directors who are also employees, and by officers of the
corporation.  Shareholders are given dissenters' rights with respect to the
vote on Control Share Acquisitions and may demand payment of the fair value
of their shares.

   A number of acquisitions of shares are deemed not to constitute Control
Share Acquisitions, including good faith gifts, transfers pursuant to wills,
purchases pursuant to an issuance by the corporation, mergers involving the
corporation which satisfy the other requirements of the Missouri Act,
transactions with a person who owned a majority of the voting power of the
corporation within the prior year, or purchases from a person who has
previously satisfied the provisions of the Control Share

                                    - 78 -
<PAGE> 81

Acquisition Statute so long as the transaction does not result in the
purchasing party having voting power after the purchase in a percentage range
(such ranges are as set forth in the immediately preceding paragraph) beyond
the range for which the selling party previously satisfied the provisions of
the statute. Additionally, a corporation may exempt itself from application of
the statute by inserting a provision in its articles of incorporation or bylaws
expressly electing not to be covered by the statute.  MBI's Restated Articles
of Incorporation and By-Laws do not contain an election to "opt out" of the
Control Share Acquisition Statute.

   Illinois has a business combination statute similar to Missouri's which
generally prohibits a domestic corporation from engaging in mergers or other
business combinations with certain "interested shareholders" for a period of
three years from the time that the person becomes an "interested
shareholder".  The three year moratorium can be avoided if (i) the business
combination or transaction in which the shareholder became an interested
shareholder is approved by the Board of Directors prior to the date on which
the interested stockholder acquires the requisite percentage of stock, (ii)
as a result of the transaction pursuant to which the shareholder became an
"interested shareholder," the interested shareholder owned 85% or more of the
voting shares of the corporation, excluding for purposes of determining the
number of shares outstanding those shares owned by (A) persons who are
directors and also officers, and (B) employee stock plans in which employee
participants do not have the right to determine confidentially whether shares
held subject to the plan will be tendered in a tender or exchange offer, or
(iii) subsequent to becoming an interested shareholder the transaction is
approved by the Board of Directors and authorized (but not by written
consent) by 66 2/3% or more of the corporation's shareholders (other than the
interested shareholder).

  DISSENTERS' RIGHTS.  Under both Section 351.455 of the Missouri Act and
Article 5, Section 11.65 of the Illinois Statute, a shareholder of any
corporation which is a party to a merger or consolidation, or which sells all
or substantially all of its assets, has the right to dissent from such
corporate action and to demand payment of the value of such shares. The
provisions of the Illinois Statute are applicable to the shareholders of
First Sterling.

  SHAREHOLDERS' RIGHT TO INSPECT.  Under Section 351.215 of the Missouri Act,
any shareholder of MBI may inspect the corporation's books and records for
any reasonable and proper purpose.  Such inspection may be made at any
reasonable time or times.  Shareholders of First Sterling have similar rights
under Article 5, Section 7.75 of the Illinois Act.

   Size of Board of Directors.  As permitted under the Missouri Act, the
number of directors on the Board of Directors of MBI is set forth in MBI's
By-Laws, which provide that the number of directors may be fixed from time to
time at not less than 12 nor more than 24 by an amendment of the By-Laws or
by a resolution of the Board of Directors, in either case, adopted by the
vote or consent of at least two-thirds of the number of directors then
authorized under the By-Laws.  MBI's Board of Directors currently has
seventeen members.  First Sterling's Board of Directors currently has eight
members.  The supermajority vote required for the amendment of MBI's By-Laws
regarding a change in the number of directors may have the effect of making
it more difficult to force an immediate change in the composition of a
majority of the Board of Directors and may be deemed to have an anti-takeover
effect.

                       SUPERVISION AND REGULATION
                       --------------------------

GENERAL

   As a bank holding company, MBI is subject to regulation under the BHCA and
its examination and reporting requirements.  Under the BHCA, a bank holding
company may not directly or indirectly acquire the ownership or control of
more than 5% of the voting shares or substantially all of the assets of any
company, including a bank or savings and loan association, without the prior
approval of the Federal Reserve Board.  In addition, bank holding companies
are generally prohibited under the BHCA from engaging in nonbanking
activities, subject to certain exceptions.

   As a savings and loan holding company, MBI is also subject to regulatory
oversight by the OTS.  As such, MBI is required to register and file reports
with the OTS and is subject to regulation by the OTS.  In addition, the OTS
has enforcement authority over MBI which permits the OTS to restrict or
prohibit activities that are determined to be a serious risk to its
subsidiary savings association.

   MBI and its subsidiaries are subject to supervision and examination by
applicable federal and state banking agencies.  The earnings of MBI's
subsidiaries, and therefore the earnings of MBI, are affected by general
economic conditions, management policies and the legislative and governmental
actions of various regulatory authorities, including the Federal Reserve
Board, the OTS, the FDIC, the Comptroller of the Currency (the
"Comptroller"), and state banking regulators.  In addition, there are
numerous governmental requirements and regulations that affect the activities
of MBI and its subsidiaries.

CERTAIN TRANSACTIONS WITH AFFILIATES

   There are various legal restrictions on the extent to which a bank holding
company and certain of its nonbank subsidiaries can borrow or otherwise
obtain credit from its bank subsidiaries.  In general, these restrictions
require that any such extensions of credit must be on non-preferential terms
and secured by designated amounts of specified collateral and be limited, as
to any one of the holding company or such nonbank subsidiaries, to 10% of the
lending bank's capital stock and surplus, and as to the holding company and
all such nonbank subsidiaries in the aggregate, to 20% of such capital stock
and surplus.

PAYMENT OF DIVIDENDS

   MBI is a legal entity separate and distinct from its banking and other
subsidiaries.  The principal source of MBI's revenues is dividends from its
national and state banking subsidiaries.  Various federal and state statutory
provisions limit the amount of dividends the affiliate banks can pay to MBI
without regulatory approval.  The approval of the appropriate bank regulator
is required for any dividend by a national bank or state member bank if the
total of all dividends declared by the bank in any calendar year would exceed
the total of its net profits, as defined by regulatory agencies, for such
year combined with its retained net profits for the preceding two years.  In
addition, a national bank or a state member bank may not pay a dividend in an
amount greater than its net profits then on hand.  The payment of dividends
by any affiliate bank may also be affected by other factors, such as the
maintenance of adequate capital for such affiliate bank.

CAPITAL ADEQUACY

   The Federal Reserve Board has issued standards for measuring capital
adequacy for bank holding companies.  These standards are designed to provide
risk-responsive capital guidelines and to

                                    - 80 -
<PAGE> 83
incorporate a consistent framework for use by financial institutions operating
in major international financial markets.  The banking regulators have issued
standards for banks that are similar to, but not identical with, the standards
for bank holding companies.

   In general, the risk-related standards require banks and bank holding
companies to maintain capital based on "risk adjusted" assets so that
categories of assets with potentially higher credit risk will require more
capital backing than categories with lower credit risk.  In addition, banks
and bank holding companies are required to maintain capital to support
off-balance sheet activities such as loan commitments.

   The standards classify total capital for this risk-based measure into two
tiers referred to as Tier 1 and Tier 2.  Tier 1 capital consists of common
shareholders' equity, certain non-cumulative and cumulative perpetual
preferred stock, and minority interests in equity accounts of consolidated
subsidiaries; Tier 2 capital consists of the allowance for loan and lease
losses (within certain limits), perpetual preferred stock not included in
Tier 1, hybrid capital instruments, term subordinated debt, and
intermediate-term preferred stock.  Bank holding companies are required to
meet a minimum ratio of 8% of qualifying total capital to risk-adjusted
assets, and a minimum ratio of 4% of qualifying Tier 1 capital to
risk-adjusted assets.  Capital that qualifies as Tier 2 capital is limited in
amount to 100% of Tier 1 capital in testing compliance with the total
risk-based capital minimum standards.

   In addition, the Federal Reserve Board has established minimum leverage
ratio guidelines for bank holding companies.  These guidelines provide for a
minimum ratio of Tier 1 capital to adjusted average total assets (the
"leverage ratio") of 3% for bank holding companies that meet certain
specified criteria, including having the highest regulatory rating.  Other
bank holding companies generally are required to maintain a leverage ratio of
at least 3% plus 100 to 200 basis points.  The guidelines also provide that
bank holding companies experiencing internal growth or making acquisitions
will be expected to maintain strong capital positions substantially above
minimum supervisory levels, without significant reliance on intangible
assets.  Furthermore, the Federal Reserve Board has indicated that it may
consider other indicia of capital strength in evaluating proposals for
expansion or new activities.

   The federal bank regulatory agencies have issued various proposals to
amend the risk- based capital guidelines for banks and bank holding
companies.  Under one proposal, banks would be required to give explicit
consideration to interest rate risk as an element of capital adequacy by
maintaining capital to compensate for such risk in an amount measured by the
bank's exposure to interest rate risk in excess of a regulatory threshold.
Another proposal would revise the treatment given to (i) low-level recourse
arrangements to reduce the amount of capital required and (ii) certain direct
credit substitutes provided by banking organizations to require that capital
be maintained against the value of the assets enhanced or the loans
protected.  A proposal recently issued by the Federal Reserve Board and
expected to be joined in by the other bank regulatory agencies increases the
amount of capital required to be carried against certain long-term derivative
contracts; in addition, the proposal recognizes the effect of certain
bilateral netting arrangements in reducing potential future exposure under
these contracts.  MBI believes that these changes will not, if adopted, have
a material effect on its compliance with capital adequacy requirements.

FDIC INSURANCE ASSESSMENTS

   The subsidiary banks of MBI are subject to FDIC deposit insurance
assessments.  The FDIC has adopted a risk-based premium schedule.  Under this
schedule, the annual premiums initially ranged from $.23 to $.31 for every
$100 of deposits.  Each financial institution is assigned to one of three
capital groups--well capitalized, adequately capitalized or
undercapitalized--and further assigned to one

                                    - 81 -
<PAGE> 84
of three subgroups within a capital group, on the basis of supervisory
evaluations by the institution's primary federal and, if applicable, state
supervisors and on the basis of other information relevant to the institution's
financial condition and the risk posed to the applicable insurance fund.  The
actual assessment rate applicable to a particular institution will, therefore,
depend in part upon the risk assessment classification so assigned to the
institution by the FDIC.  See "- FIRREA and FDICIA."

   The legislation adopted in August 1989 to provide for the resolution of
insolvent savings associations also required the FDIC to establish separate
deposit insurance funds -- the Bank Insurance Fund ("BIF") for banks and the
Savings Association Insurance Fund ("SAIF") for savings associations.  The
law also requires the FDIC to set deposit insurance assessments at such
levels as will cause BIF and SAIF to reach their "designated reserve ratios"
of 1.25 percent of the deposits insured by them within a reasonable period of
time.  Due to low costs of resolving bank insolvencies in the last few years,
BIF reached its designated reserve ratio in May, 1995.  As a result, FDIC
recently lowered deposit insurance assessment rates on banks by revising the
range to $.04 to $.31 for every $100 of deposits.  However, the balance in
SAIF is not expected to reach the designated reserve ratio until about the
year 2002, as the law provides that a significant portion of the costs of
resolving past insolvencies of savings associations must be paid from this
source.

   MBI, which has acquired substantial amounts of SAIF-insured deposits
during the years from 1989 to the present, is required to pay deposit
insurance premiums on these SAIF-insured deposits.  Currently, SAIF-member
institutions pay deposit insurance premiums based on a schedule of from $0.23
to $0.31 per $100 of deposits.  Bills have recently been proposed by the U.S.
Congress to recapitalize the SAIF through a one-time special assessment of
approximately 85 basis points on the amount of deposits held by the
institution.  If such special assessment occurs, it is expected that the
deposit premiums paid by the SAIF-member institutions would be reduced to
approximately $0.04 for every $100 of deposits and would have the effect of
immediately reducing the capital of SAIF-member institutions by the amount of
the fee (provided SAIF-member institutions are not permitted to amortize the
expense of the one-time fee over a period of years).  MBI cannot predict
whether the special assessment proposal will be enacted, or, if enacted, the
amount of any one-time fee or whether ongoing SAIF premiums will be reduced
to a level equal to that of BIF premiums.  If the one-time assessment is not
enacted, it is presently expected that the SAIF will not be recapitalized
until 2002 and the disparity between SAIF and BIF deposit premiums will
continue.  MBI does not expect that either such additional deposit insurance
costs or the proposed one-time assessment will have a significant, adverse
effect on its earnings.

PROPOSALS TO OVERHAUL THE SAVINGS ASSOCIATION INDUSTRY

   Proposals recently have been introduced in the U.S. Congress that, if
adopted, would overhaul the savings association industry.  The most
significant of these proposals would recapitalize the SAIF through a one-time
special assessment (See "- FDIC Insurance Assessment"), spread the FICO Bond
obligation across the BIF and SAIF, merge the Comptroller and the OTS,
abolish the federal savings association charter, require federal thrifts to
convert to commercial banks and merge the SAIF and the BIF.  MBI cannot
predict whether these or any other legislative proposals will be enacted, or,
if enacted, the final form of the law.

SUPPORT OF SUBSIDIARY BANKS

   Under Federal Reserve Board policy, MBI is expected to act as a source of
financial strength to each subsidiary bank and to commit resources to support
each of the subsidiaries in circumstances where it might not choose to do so
absent such a policy.  This support may be required at times when MBI may not
find itself able to provide it.  In addition, any capital loans by MBI to any
of

                                    - 82 -
<PAGE> 85
its subsidiaries would also be subordinate in right of payment to deposits
and certain other indebtedness of such subsidiary.

   Consistent with this policy regarding bank holding companies serving as a
source of financial strength for their subsidiary banks, the Federal Reserve
Board has stated that, as a matter of prudent banking, a bank holding company
generally should not maintain a rate of cash dividends unless its net income
available to common shareholders has been sufficient to fully fund the
dividends, and the prospective rate of earnings retention appears consistent
with the bank holding company's capital needs, asset quality and overall
financial condition.

FIRREA AND FDICIA

   The Financial Institutions Reform, Recovery, and Enforcement Act of 1989
("FIRREA") contains a cross-guarantee provision which could result in insured
depository institutions owned by MBI being assessed for losses incurred by
the FDIC in connection with assistance provided to, or the failure of, any
other insured depository institution owned by MBI.  Under FIRREA, failure to
meet the capital guidelines could subject a banking institution to a variety
of enforcement remedies available to federal regulatory authorities,
including the termination of deposit insurance by the FDIC.

   The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") made extensive changes to the federal banking laws.  FDICIA
instituted certain changes to the supervisory process, including provisions
that mandate certain regulatory agency actions against undercapitalized
institutions within specified time limits.  FDICIA contains various other
provisions that may affect the operations of banks and savings institutions.

   The prompt corrective action provision of FDICIA requires the federal
banking regulators to assign each insured institution to one of five capital
categories ("well capitalized," "adequately capitalized" or one of three
"undercapitalized" categories) and to take progressively more restrictive
actions based on the capital categorization, as specified below.  Under
FDICIA, capital requirements would include a leverage limit, a risk-based
capital requirement and any other measure of capital deemed appropriate by
the federal banking regulators for measuring the capital adequacy of an
insured depository institution.  All institutions, regardless of their
capital levels, are restricted from making any capital distribution or paying
any management fees that would cause the institution to fail to satisfy the
minimum levels for any relevant capital measure.  An institution that fails
to meet the minimum level for any relevant capital measure (an
"undercapitalized institution") may be:  (i) subject to increased monitoring
by the appropriate federal banking regulator; (ii) required to submit an
acceptable capital restoration plan within 45 days; (iii) subject to asset
growth limits; and (iv) required to obtain prior regulatory approval for
acquisitions, branching and new lines of businesses.  The capital restoration
plan must include a guarantee by the institution's holding company (under
which the holding company would be liable up to the lesser of 5% of the
institution's total assets or the amount necessary to bring the institution
into capital compliance as of the date it failed to comply with its capital
restoration plan) that the institution will comply with the plan until it has
been adequately capitalized on average for four consecutive quarters.

   The FDIC and the Federal Reserve Board adopted capital-related regulations
under FDICIA.  Under those regulations, a bank will be well capitalized if
it:  (i) had a risk-based capital ratio of 10% or greater; (ii) had a ratio
of Tier 1 capital to risk-adjusted assets of 6% or greater; (iii) had a ratio
of Tier 1 capital to adjusted total assets of 5% or greater; and (iv) was not
subject to an order, written agreement, capital directive, or prompt
corrective action directive to meet and maintain a specific capital level for
any capital measure.  A bank will be adequately capitalized if it was not
"well capitalized" and:  (i) had a risk-based capital ratio of 8% or greater;
(ii) had a ratio of Tier 1 capital to risk-adjusted

                                    - 83 -
<PAGE> 86
assets of 4% or greater; and (iii) had a ratio of Tier 1 capital to adjusted
total assets of 4% or greater (except that certain associations rated
"Composite 1" under the federal banking agencies' CAMEL rating system may be
adequately capitalized if their ratios of core capital to adjusted total assets
were 3% or greater).

   FDICIA also makes extensive changes in existing rules regarding audits,
examinations and accounting.  It generally requires annual on-site, full
scope examinations by each bank's primary federal regulator.  It also imposes
new responsibilities on management, the independent audit committee and
outside accountants to develop or approve reports regarding the effectiveness
of internal controls, legal compliance and off-balance sheet liabilities and
assets.

DEPOSITOR PREFERENCE STATUTE

   Legislation enacted in August 1993 provides a preference for deposits and
certain claims for administrative expenses and employee compensation against
an insured depository institution, such as First Sterling's and MBI's insured
bank subsidiaries, in the liquidation or other resolution of such an
institution by any receiver.  Such obligations would be afforded priority
over other general unsecured claims against such an institution, including
federal funds and letters of credit, as well as any obligation to
shareholders of such an institution in their capacity as such.

THE INTERSTATE BANKING AND COMMUNITY DEVELOPMENT LEGISLATION

   In September 1994, legislation was enacted that may have a significant
effect in restructuring the banking industry in the United States.  The
Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994
facilitates the interstate expansion and consolidation of banking
organizations by permitting (i) bank holding companies that are adequately
capitalized and managed to acquire banks located in states outside their home
states regardless of whether such acquisitions are authorized under the law
of the host state, (ii) the interstate merger of banks after June 1, 1997,
subject to the right of individual states to "opt in" or to "opt out" of this
authority before that date, (iii) banks to establish new branches on an
interstate basis provided that such action is specifically authorized by the
law of the host state, (iv) foreign banks to establish, with approval of the
regulators in the United States, branches outside their home states to the
same extent that national or state banks located in the home state would be
authorized to do so, and (v) banks to receive deposits, renew time deposits,
close loans, service loans and receive payments on loans and other
obligations as agent for any bank or thrift affiliate, whether the affiliate
is located in the same state or a different state.  One effect of this
legislation is to permit MBI to acquire banks located in any state and to
permit bank holding companies located in any state to acquire banks and bank
holding companies in Missouri.  Overall, this legislation is likely to have
the effects of increasing competition and promoting geographic
diversification in the banking industry.

   The Riegle Community Development and Regulatory Improvement Act of 1994,
also enacted in September 1994, is intended to (i) increase the flow of loans
to businesses in distressed communities by providing incentives to lenders to
provide credit within those communities, (ii) remove impediments to the
securitization of small business loans, (iii) provide for a reduction in
paperwork and to streamline bank regulation through, for example, the
coordination of examinations in a bank holding company context, a reduction
in the number of currency transaction reports required and improvements to
the National Flood Insurance Program that include enabling lenders to force
place flood insurance and (iv) increase the level of consumer protection
provided to customers in banking transactions.  MBI believes that these
provisions of the new law will not have a material effect on its operation.

                 REPORT OF INDEPENDENT AUDITORS


Board of Directors and Shareholders
First Sterling Bancorp, Inc.
Sterling, Illinois


We have audited the accompanying consolidated balance sheet of First Sterling
Bancorp, Inc. as of December 31, 1994, and the related consolidated
statements of income, changes in shareholders' equity, and cash flows for the
year then ended.  These financial statements are the responsibility of the
Company's management.  Our responsibility is to express an opinion on these
financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements.
An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation.  We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of First
Sterling Bancorp, Inc. as of December 31, 1994, and the results of its
operations and its cash flows for the year then ended in conformity with
generally accepted accounting principles.

As discussed in Note 2 to the consolidated financial statements, the Company
changed its method of accounting for securities during 1994.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation and Basis of Presentation:  The consolidated financial
- ---------------------------------------
statements of First Sterling Bancorp, Inc. (the "Company") include the
accounts of its wholly-owned subsidiary, First National Bank of Sterling -
Rock Falls (the "Bank").  Prior to 1994, the Bank was a wholly-owned
subsidiary of Rock Falls Bancshares, Inc. ("Rock Falls") while Rock Falls was
a wholly-owned subsidiary of the Company.  Rock Falls was merged into the
Company in 1994.  First National Bank of Sterling ("FNBS") and Rock Falls
National Bank ("RFNB") merged their operations in December of 1991.  The
surviving bank was named First National Bank of Sterling - Rock Falls.  Prior
to the merger, FNBS was a wholly-owned subsidiary of the Company and RFNB was
a wholly-owned subsidiary of Rock Falls.

The Company's acquisition of the FNBS in 1983 was accounted for as a
purchase.  The excess of the purchase price over the fair value of net assets
acquired is being amortized over twelve years on the straight-line method.

On January 17, 1990, the Company acquired all of the outstanding common stock
of Rock Falls for cash in the amount of $4,300,000.  The acquisition has been
accounted for by the purchase method of accounting and, accordingly, the
acquired assets and liabilities assumed have been recorded at their estimated
fair market values at the date of acquisition and the resulting adjustments
are being amortized over their respective lives.

Significant intercompany accounts and transactions have been eliminated in
the consolidated financial statements.

The accompanying interim condensed consolidated financial statements as of
September 30, 1995 and for the nine months ended September 30, 1995 and 1994
are prepared without audit and reflect all adjustments which are of a normal
and recurring nature and, in the opinion of management, are necessary to
present interim financial statements of the Company in accordance with
generally accepted accounting principles.  The interim financial statements
do not purport to contain all the necessary financial disclosures covered by
generally accepted accounting principles that might otherwise be necessary
for complete financial statements.

The interim condensed consolidated financial statements should be read in
conjunction with the consolidated financial statements and accompanying notes
of the Company for the years ended December 31, 1994, 1993, and 1992.

The results of operations for the nine-month period ended September 30, 1995,
are not necessarily indicative of the results to be expected for the full
year.

      (Table amounts in thousands of dollars, except per share data)

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

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Cash and Cash Equivalents:  For purposes of reporting cash flows, cash and
- -------------------------
cash equivalents include cash on hand, noninterest-bearing amounts due from
banks, money market fund investments, and federal funds sold.  Generally,
federal funds are sold for one-day periods.

Securities:  Beginning January 1, 1994, debt securities are classified as
- ----------
held-to-maturity when the Company has the positive intent and ability to hold
those securities to maturity.  Accordingly, securities held-to-maturity are
stated at cost, adjusted for amortization of premiums and accretion of
discounts.  All other securities are classified as available-for-sale since
the Company may decide to sell those securities in response to changes in
market interest rates, liquidity needs, changes in the Company's tax
situation, changes in yields on alternative investments and for other
reasons.  Securities available-for-sale are carried at fair value with
unrealized gains and losses charged or credited, net of deferred income
taxes, to a valuation allowance included as a separate component of equity.
Realized gains and losses on disposition are based on the net proceeds and
the adjusted carrying amounts of the securities sold, using the specific
identification method.

Loans and Loan Income:  Loans are stated net of unearned income, deferred
- ---------------------
loan fees, and the allowance for loan losses.  Interest income on real
estate, commercial and agricultural, and most installment loans is accrued on
the simple interest method over the terms of the respective loans based upon
principal balances outstanding.  For other installment loans, unearned income
is recognized as income using a method which approximates the interest
method.  Where serious doubt exists as to the collectibility of a loan, the
accrual of interest is discontinued.  Loan fees, net of direct loan
origination costs, are deferred and recognized over the life of the loan as a
yield adjustment.

Statement of Financial Accounting Standards No. 114 and No. 118 were adopted
at January 1, 1995.  Under these standards, loans considered to be impaired
are reduced to the present value of expected future cash flows or to the fair
value of collateral, by allocating a portion of the allowance for loan losses
to such loans.  If these allocations cause the allowance for loan losses to
require an increase, such increase is reported as part of the provision for
loan losses.  The effect of adopting these standards was not material to the
Company's consolidated financial position.

Beginning in 1995, for impairment recognized in accordance with SFAS 114, the
entire change in present value of expected cash flows or current collateral
value is reported as bad debt expense in the same manner in which impairment
initially was recognized or as a reduction in the amount of bad debt expense
that otherwise would be reported.

Office Buildings and Equipment:  Office buildings and equipment are stated
- ------------------------------
at cost less accumulated depreciation.  Office buildings and related
components are depreciated primarily on the straight-line method over
estimated useful lives ranging from fifteen to forty years.  Equipment and
furniture are depreciated on both the straight-line and accelerated methods
over estimated useful lives ranging from three to fifteen years.

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

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Other Real Estate:  Real estate owned, other than that used in the normal
- -----------------
course of business, is carried at the lower of cost or fair value less
estimated selling expenses.  Any reduction to fair value from a related loan
at the time of acquisition is accounted for as a loan loss.

Income Taxes:  The provision for income taxes is based on an asset and
- ------------
liability approach that requires recognition of deferred tax assets and
liabilities for the expected future tax consequences of temporary differences
between the carrying amounts and the tax bases of assets and liabilities.
See Note 9 regarding change in accounting method.

Earnings Per Share: Earnings per share are computed based on the weighted
- ------------------
average number of shares outstanding during the period.

Book Value Per Share:  Book value per share is computed by dividing total
- --------------------
shareholders' equity by the number of common shares outstanding at each date.


NOTE 2 - SECURITIES

Effective January 1, 1994, the Company adopted Statement of Financial
Accounting Standards No. 115 ("SFAS  115"), "Accounting for Certain
Investments in Debt and Equity Securities".  SFAS 115 requires
classifications of debt securities as either held-to-maturity, trading or
available-for-sale.  The cumulative effect of adopting SFAS  115 increased
shareholders' equity at January 1, 1994 by $578,000, which is the after tax
effect of the adjustment from amortized cost to fair value for securities
available-for-sale at that date.  The 1993 and 1992 financial statements
reflect the terminology contained in SFAS 115.

The Bank is a party to financial instruments with off-balance-sheet risk in
the normal course of business to meet the financing needs of its customers.
These financial instruments include commitments to make loans, standby
letters of credit, and unused lines of credit.  The Bank's exposure to credit
loss in the event of nonperformance by the other parties to these financial
instruments is represented by the contractual amount of the instruments.  The
Bank uses the same credit policy to make such commitments as is used for
on-balance-sheet items.

<TABLE>
These financial instruments are summarized as follows:

Since many commitments to make loans expire without being used, the amounts
above do not necessarily represent future cash commitments.  Collateral
obtained upon exercise of the commitment is determined using management's
credit evaluation of the borrower, and may include commercial and residential
real estate and other business and consumer assets.

</TABLE>

Depreciation expense was $203,000, $261,000 and $199,000 in 1994, 1993 and
1992, respectively.

NOTE 6 - INTANGIBLE ASSETS

The intangible value assigned to RFNB's core deposits was $643,000 at the
acquisition date.  The carrying value of the core deposit intangible asset
was $245,000 and $293,000 at December 31, 1994 and 1993, respectively.

The core deposit intangible asset was determined in consideration of the
value of RFNB's noninterest bearing demand, NOW, savings, and money market
deposit accounts.  The valuation method estimated annual cash flow
differentials of the core deposit interest and handling costs as compared to
the interest and handling costs of alternative funds sources, such as
certificates of deposit, and then discounted such cash flow differentials to
their present value.

NOTE 6 - INTANGIBLE ASSETS (Continued)

The core deposit intangible asset is being amortized over ten years on an
accelerated method.  Amortization charged to expense was $48,000, $80,000 and
$86,000 in 1994, 1993 and 1992, respectively.

The unamortized excess purchase price resulting from the Company's
acquisition of FNBS was $0, $33,000 and $165,000 at September 30, 1995,
December 31, 1994 and 1993, respectively, and is included in intangible
assets in the balance sheet.  Amortization expense was $132,000 for each of
the years ended December 31, 1994, 1993 and 1992.


NOTE 7 - RETAINED EARNINGS AND CAPITAL REQUIREMENTS

Banking regulations limit the amount of dividends that banks may pay without
the prior approval of their regulatory agency.  The subsidiary Bank had
approximately $1,333,000 of retained earnings against which dividends may be
charged without prior approval as of December 31, 1994.

The Company is required to maintain a minimum ratio of total capital to
risk-weighted assets (including certain off-balance sheet activities, such as
standby letters of credit) of 8%.  At least half of the total capital is
required to be "Tier 1 Capital".  Under these guidelines, the Company's Tier
1 Capital consists of common stockholders' equity (exclusive of unrealized
gains and losses, net of tax, on securities available-for-sale) less
intangible assets.  The Company's total capital consists of Tier 1 Capital
plus the allowance for loan losses.  Risk-based capital ratios are calculated
with the reference to risk-weighted assets including certain off-balance
sheet exposures.  As of December 31, 1994, the Company's Tier 1 and total
capital risk weighted ratios were approximately 16.7% and 17.9, respectively.

In addition to the risk-based capital requirements, the Federal Reserve
System requires a minimum leverage ratio (Tier 1 Capital to total assets) of
3%, provided that all but the highest rated bank holding companies which are
not experiencing or anticipating significant growth are expected to maintain
a ratio of 1% to 2% above the stated minimum.  The Company's leverage ratio
at December 31, 1994 was 10.48%

Per the terms of the merger agreement discussed in Note 13, the Company's
dividends per share are limited to $.04 per quarter through the completion of
the merger transaction.

NOTE 8 - PROFIT SHARING PLAN

The Bank maintains a profit sharing plan covering substantially all
employees.  The plan includes a 401(k) feature.  The Bank matches 25% of the
first 4% of compensation which each employee voluntarily contributes to the
plan.  Additional contributions to the plan are determined at the discretion
of the Bank's Board of Directors.  Profit sharing expense was $151,000,
$143,000 and $119,000 for the years ended December 31, 1994 and 1993 and
1992, respectively.


NOTE 9 -INCOME TAXES

The provision for income taxes for the nine months ended September 30, 1995
and 1994 represents tax expense calculated using annualized rates on taxable
income generated during the respective periods.  For the nine months ended
September 30, 1995 and 1994, the provision for income taxes was less than the
amounts computed by applying the statutory corporate tax vote of 34% to
income before income taxes.  The reasons for the differences are
substantially the same as for the year ended December 31, 1994.

Beginning in 1993, the Company adopted Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes" ("SFAS 109").  The adoption
of SFAS 109 changed the Company's method of accounting for income taxes from
the deferred method (Accounting Principles Board Opinion No. 11) to an asset
and liability approach.  The asset and liability approach requires the
recognition of deferred tax liabilities and assets for the expected future
tax consequences of temporary differences between the carrying amounts and
the tax bases of assets and liabilities.  The cumulative effect of this
change was $202,000 and primarily represents the impact of adjusting deferred
taxes to reflect current tax rates and recognizing alternative minimum tax
credit carryforwards as deferred tax assets.

<TABLE>
The provision for federal income taxes for the years ended December 31, 1994,
1993 and 1992, consists of the following:

NOTE 10 - COMMITMENTS AND CONTINGENCIES

From time to time, the Company and the Bank are involved in legal actions
arising in the ordinary course of business.  Management believes the ultimate
liability from such actions, if any, will not have a material effect on the
Company's financial condition.


NOTE 11 - DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which it is practicable to estimate
that value.

Cash and Cash Equivalents:  For those short-term instruments, the carrying
- -------------------------
amount is a reasonable estimate of fair value.

Securities:  For securities, fair value equals quoted market price, if
- ----------
available.  If a quoted market price is not available, fair value is
estimated using quoted market prices of similar securities.

Loans:  The fair value of loans is estimated by discounting future cash
- -----
flows using the current rates at which similar loans would be made to
borrowers with similar credit ratings for the same remaining
maturities.

Board of Directors
First Sterling Bancorp, Inc.
305 4th Avenue
Sterling, IL  61081

Members of the Board:

   
   You have requested our opinion as to the fairness, from a financial point
of view, of the merger consideration (the "Merger Consideration") to be
received by the shareholders of First Sterling Bancorp, Inc. ("Sterling")
pursuant to the Agreement and Plan of Merger (the "Agreement"), dated July 24,
1995, between Sterling, Mercantile Bancorporation Inc. ("Mercantile"), and its
wholly owned subsidiary Mercantile Bancorporation Incorporated of Illinois
("MB Illinois").  As set forth in the Agreement, Sterling will be merged
with and into MB Illinois and each outstanding share of Common Stock of
Sterling will be converted into and be exchangeable for 0.1415 shares of
Common Stock, $5.00 par value, of Mercantile and the associated "Rights" under
the "Rights Agreement" as defined in the Agreement.

   During the course of our engagement, we have, among other
things:

   1) reviewed the Agreement, the financial statements for Sterling for the
three fiscal years ended December 31, 1994 and for Mercantile for the three
fiscal years ended December 31, 1994, and the interim financial statements for
Sterling and Mercantile for the period ended September 30, 1995 as provided to
us, as well as other internally generated Sterling reports relating to
asset/liability management, asset quality and so forth;
    

   2) reviewed and analyzed other material bearing upon the
financial and operating condition of Mercantile and Sterling and
material prepared in connection with the proposed transaction;

   3) reviewed the operating characteristics of certain other
financial institutions deemed relevant to the contemplated
transaction;

   4) reviewed the nature and terms of recent sale and merger
transactions involving banks, bank holding companies and other
financial institutions that we consider relevant;

   5) reviewed historical and current market data for Mercantile
common stock;

   6) reviewed financial and other information provided to us by
the managements of Mercantile and Sterling;

   7) conducted meetings with members of the senior management of
Mercantile and Sterling for the purpose of reviewing the future
prospects of Mercantile and Sterling; and

   8) evaluated the pro forma ownership of Mercantile common
stock by Sterling shareholders, relative to the pro forma
contribution of Sterling's assets, liabilities, equity and
earnings to the pro forma company.

                                   -------

   Following is the text of the dissenters' rights provisions set forth at
Sections 11.65 and 11.70, respectively, of the Illinois Business Corporation
Act of 1983, as amended:

   Sec. 11.65.  Right to Dissent.  (a)  A shareholder of a corporation is
entitled to dissent from, and obtain payment for his or her shares in the
event of any of the following corporate actions:  (1) consummation of a plan
of merger or consolidation or a plan of share exchange to which the
corporation is a party if (i) shareholder authorization is required for the
merger or consolidation or the share exchange by Section 11.20 or the articles
of incorporation or (ii) the corporation is a subsidiary that is merged with
its parent or another subsidiary under Section 11.30; (2) consummation of
sale, lease or exchange of all, or substantially all, of the property and
assets of the corporation other than in the usual and regular course of
business; (3) an amendment of the articles of incorporation that materially
and adversely affects rights in respect of a dissenter's shares because it:
(i) alters or abolishes a preferential right of such shares; (ii) alters or
abolishes a right in respect of redemption, including a provision respecting a
sinking fund for the redemption or repurchase, of such shares; (iii) in the
case of a corporation incorporated prior to January 1, 1982, limits or
eliminates cumulative voting rights with respect to such shares; or (4) any
other corporate action taken pursuant to a shareholder vote if the articles of
incorporation, by-laws, or a resolution of the board of directors provide that
shareholders are entitled to dissent and obtain payment for their shares in
accordance with the procedures set forth in Section 11.70 or as may be
otherwise provided in the articles, by-laws or resolution.

   (b)   A shareholder entitled to dissent and obtain payment for his or her
shares under this Section may not challenge the corporate action creating his
or her entitlement unless the action is fraudulent with respect to the
shareholder or the corporation or constitutes a breach of a fiduciary duty
owed to the shareholder.

   (c)   A record owner of shares may assert dissenters' rights as to fewer
than all the shares recorded in such person's name only if such person
dissents with respect to all shares beneficially owned by any one person and
notifies the corporation in writing of the name and address of each person on
whose behalf the record owner asserts dissenters' rights.  The rights of a
partial dissenter are determined as if the shares as to which dissent is made
and the other shares were recorded in the names of different shareholders.  A
beneficial owner of shares who is not the record owner may assert dissenters'
rights as to shares held on such person's behalf only if the beneficial owner
submits to the corporation the record owner's written consent to the dissent
before or at the same time the beneficial owner asserts dissenters' rights.

   Sec. 11.70.  Procedure to Dissent.  (a) If the corporate action giving rise
to the right to dissent is to be approved at a meeting of shareholders, the
notice of meeting shall inform the shareholders of their right to dissent and
the procedure to dissent.  If, prior to the meeting, the corporation furnishes
to the shareholders material information with respect to the transaction that
will objectively enable a shareholder to vote on the transaction and to
determine whether or not to exercise dissenters' rights, a shareholder may
assert dissenter' rights only if the shareholder delivers to the corporation
before the vote is taken a written demand for payment for his or her shares if
the proposed action is consummated, and the shareholder does not vote in favor
of the proposed action.

   (b)   If the corporate action giving rise to the right to dissent is not to
be approved at a meeting of shareholders, the notice to shareholders
describing the action taken under Section 11.30 or Section 7.10 shall inform
the shareholders of their right to dissent and the procedure to dissent.  If,
prior to or concurrently with the notice, the corporation furnishes to the
shareholders material information with respect to the transaction that will
objectively enable a shareholder to determine whether or not to exercise

                                    B - 1
<PAGE> 118
dissenters' rights, a shareholder may assert dissenter's rights only if he or
she delivers to the corporation within 30 days from the date of mailing the
notice a written demand for payment for his or her shares.

   (c)   Within 10 days after the date on which the corporate action giving
rise to the right to dissent is effective or 30 days after the shareholder
delivers to the corporation the written demand for payment, whichever is
later, the corporation shall send each shareholder who has delivered a written
demand for payment a statement setting forth the opinion of the corporation as
to the estimated fair value of the shares, the corporation's latest balance
sheet as of the end of a fiscal year ending not earlier than 16 months before
the delivery of the statement, together with the statement of income for that
year and the latest available interim financial statements, and either a
commitment to pay for the shares of the dissenting shareholder at the
estimated fair value thereof upon transmittal to the corporation of the
certificate or certificates, or other evidence of ownership, with respect to
the shares, or instructions to the dissenting shareholder to sell his or her
shares within 10 days after delivery of the corporation's statement to the
shareholder.  The corporation may instruct the shareholder to sell only if
there is a public market for the shares at which the shares may be readily
sold.  If the shareholder does not sell within that 10 day period after being
so instructed by the corporation, for purposes of this Section the shareholder
shall be deemed to have sold his or her shares at the average closing price of
the shares, if listed on a national exchange, or the average of the bid and
asked price with respect to the shares quoted by a principal market maker, if
not listed on a national exchange, during that 10 day period.

   (d)   A shareholder who makes written demand for payment under this Section
retains all other rights of a shareholder until those rights are cancelled or
modified by the consummation of the proposed corporate action.  Upon
consummation of that action, the corporation shall pay to each dissenter who
transmits to the corporation the certificate or other evidence of ownership of
the shares the amount the corporation estimates to be the fair value of the
shares, plus accrued interest, accompanied by a written explanation of how the
interest was calculated.

   (e)  If the shareholder does not agree with the opinion of the corporation
as to the estimated fair value of the shares or the amount of interest due,
the shareholder, within 30 days from the delivery of the corporation's
statement of value, shall notify the corporation in writing of the
shareholder's estimated fair value and amount of interest due and demand
payment for the difference between the shareholder's estimate of fair value
and interest due and the amount of the payment by the corporation or the
proceeds of sale by the shareholder, whichever is applicable because of the
procedure for which the corporation opted pursuant to subsection (c).

   (f)   If, within 60 days from delivery to the corporation of the
shareholder notification of estimate of fair value of the shares and interest
due, the corporation and the dissenting shareholder have not agreed in writing
upon the fair value of the shares and interest due, the corporation shall
either pay the difference in value demanded by the shareholder, with interest,
or file a petition in the circuit court of the county in which either the
registered office or the principal office of the corporation is located,
requesting the court to determine the fair value of the shares and interest
due.  The corporation shall make all dissenters, whether or not residents of
this State, whose demands remain unsettled parties to the proceeding as an
action against their shares and all parties shall be served with a copy of the
petition.  Nonresidents may be served by registered or certified mail or by
publication as provided by law.  Failure of the corporation to commence an
action pursuant to this Section shall not limit or affect the right of the
dissenting shareholders to otherwise commence an action as permitted by law.

   (g)   The jurisdiction of the court in which the proceeding is commenced
under subsection (f) by a corporation is plenary and exclusive.  The court may
appoint one or more persons as appraisers to receive evidence and recommend
decision on the question of fair value.  The appraisers have the power
described in the order appointing them, or in any amendment to it.

                                    B - 2
<PAGE> 119
   (h)   Each dissenter made a party to the proceeding is entitled to judgment
for the amount, if any, by which the court finds that the fair value of his or
her shares, plus interest, exceeds the amount paid by the corporation or the
proceeds of sale by the shareholder, whichever amount is applicable.

   (i)   The court, in a proceeding commenced under subsection (f), shall
determine all costs of the proceeding, including the reasonable compensation
and expenses of the appraisers, if any, appointed by the court under
subsection (g), but shall exclude the fees and expenses of counsel and experts
for the respective parties.  If the fair value of the shares as determined by
the court materially exceeds the amount which the corporation estimated to be
the fair value of the shares or if no estimate was made in accordance with
subsection (c), then all or any part of the costs may be assessed against the
corporation.  If the amount which any dissenter estimated to be the fair value
of the shares materially exceeds the fair value of the shares as determined by
the court, then all or any part of the costs may be assessed against that
dissenter.  The court may also assess the fees and expenses of counsel and
experts for the respective parties, in amounts the court finds equitable, as
follows:

      (1)   Against the corporation and in favor of any or all
dissenters if the court finds that the corporation did not
substantially comply with the requirements of subsections (a),
(b), (c), (d), or (f).

      (2)   Against either the corporation or a dissenter and in
favor of any other party if the court finds that the party against
whom the fees and expenses are assessed acted arbitrarily,
vexatiously, or not in good faith with respect to the rights
provided by this Section.

   If the court finds that the services of counsel for any
dissenter were of substantial benefit to other dissenters
similarly situated and that the fees for those services should not
be assessed against the corporation, the court may award to that
counsel reasonable fees to be paid out of the amounts awarded to
the dissenters who are benefited.  Except as otherwise provided in
this Section, the practice, procedure, judgment and costs shall be
governed by the Code of Civil Procedure.

   (j)   As used in this Section:

      (1)   "Fair value", with respect to a dissenter's shares,
means the value of the shares immediately before the consummation
of the corporate action to which the dissenter objects excluding
any appreciation or depreciation in anticipation of the corporate
action, unless exclusion would be inequitable.

      (2)   "Interest" means interest from the effective date of
the corporate action until the date of payment, at the average
rate currently paid by the corporation on its principal bank loans
or, if none, at a rate that is fair and equitable under all the
circumstances.
