                      AGREEMENT AND PLAN OF REORGANIZATION

This Agreement and Plan of Reorganization (this "Agreement") is made and entered
into as of the 6th day of March, 2001, by and among CIB Marine Bancshares, Inc.,
a Wisconsin corporation ("CIBM"), Citrus Financial Services, Inc., a Florida
corporation ("CFSI"), and Citrus Bank, N.A., a federally chartered commercial
bank (the "Bank").

WHEREAS, the Boards of Directors of CIBM, CFSI and the Bank have determined that
it is in the best interests of their respective companies and stockholders to
consummate the business combination transaction provided for in this Agreement,
whereby CIBM Acquisition Corporation (CIBMAC), a corporation to be duly
organized in the State of Florida as a wholly-owned subsidiary of CIBM, will be
merged with and into CFSI (the "Merger");

WHEREAS, this Agreement provides for the Merger and the conversion of all
validly issued and outstanding shares of common stock of CFSI, par value $3.15
per share (sometimes referred to herein as the "CFSI Common Stock"), into shares
of common stock of CIBM, par value $1.00 per share (sometimes referred to herein
as the "CIBM Common Stock"), all in accordance with the terms and conditions of
the Plan of Merger (as defined in Section 1.1 of this Agreement);

WHEREAS, CFSI owns 100 percent of the issued and outstanding capital stock of
the Bank; and

WHEREAS, the parties hereto desire and intend that the Merger qualify as a
reorganization in accordance with Sections 368(a)(1)(A) and 368(a)(2)(E) of the
Internal Revenue Code of 1986, as amended (the "Code").

NOW THEREFORE, with the foregoing recitals incorporated herein by this
reference, and in consideration of the mutual representations, warranties,
covenants, agreements and conditions herein contained, the parties hereto
covenant and agree as follows:


                                    ARTICLE I
                                   THE MERGER

     1.1  The Merger. Subject to the terms and conditions of this Agreement and
the Plan of Merger, a copy of which is attached hereto as Exhibit A (the "Plan
of Merger"), at the Effective Date (as defined in Section 1.4 hereof), CIBMAC
shall be merged with and into CFSI, the separate corporate existence of CIBMAC
shall cease and CFSI shall be the surviving corporation under the name of Citrus
Financial Services, Inc. pursuant to the Florida Business Corporation Act (the
"FBCA") and the Bank Holding Company Act of 1956, as amended (the "BHCA"). The
Plan of Merger shall be authorized, approved and executed by and between CIBM
and CFSI, and provides, inter alia, that:

          (a) the Articles of Incorporation of CFSI as in effect immediately
prior to the Effective Date, shall be, from and after the Effective Date, the
Articles of Incorporation of the surviving corporation;

          (b) the Bylaws of CFSI in effect immediately prior to the Effective
Date shall be, from and after the Effective Date, the Bylaws of the surviving
corporation;

          (c)  the officers and directors of the surviving corporation shall be
as set forth in the Plan of Merger.

     1.2  Closing Date. The consummation of the transactions contemplated by
this Agreement and the Plan of Merger shall take place at a closing (the
"Closing"). The Closing shall be held upon the satisfaction or waiver of all of
the conditions to the Merger set forth herein and in the Plan of Merger, and
shall be held on the fifteenth day of the month following the last day of the
month in which all of the conditions to the Merger have been satisfied (the
"Closing Date"). The Closing shall take place at 10:00 a.m., local time, on the
Closing Date at the offices of CFSI located at 1717 Indian River Boulevard,

                                                                          PAGE 2

100, Vero Beach, Florida, or at such other place upon which the parties may
agree. CIBM and CFSI presently intend that the Closing will take place on or
before the date 180 days following the date of this Agreement, or such other
date as mutually agreed to by the parties.

     1.3  Actions at Closing. At the Closing, the parties shall (i) exchange the
various documents contemplated hereby and (ii) cause Articles of Merger to be
filed with the Secretary of State of the State of Florida (the "Florida
Secretary of State"), as provided by applicable Florida law. Upon verification
that the Merger has become effective as provided by Florida law, CIBM and CFSI
shall take all actions provided for in the Plan of Merger for delivery of CIBM
Common Stock and cash in lieu of fractional shares in exchange for CFSI Common
Stock pursuant to this Agreement and the Plan of Merger.

     1.4  Effective Date. The Merger shall be consummated upon the filing of
properly executed Articles of Merger with the Florida Secretary of State in the
manner and form provided for by applicable Florida law. The effective time of
the Merger shall be the close of Business on the day of the Closing or such
other time and date within five business days after the Closing as CIBM and CFSI
may mutually agree and specify in the Articles of Merger (the "Effective Date").

     1.5  Conversion of Shares.

          (a)  Subject to the consummation of the Merger in accordance with the
terms and provisions of this Agreement and the Plan of Merger, all CFSI Common
Stock shall be converted into such number of shares of CIBM Common Stock as
determined pursuant to Section 1.5(b) of this Agreement on the Effective Date,
subject to Section 1.5(c) of this Agreement. On or before the Effective Date,
CIBM shall authorize the issuance of, and shall make available, a sufficient
number of shares of common stock of CIBM that shareholders of CFSI shall be
entitled to receive pursuant to this Agreement and the Plan of Merger. As
provided in this Agreement and Plan of Merger, no fractional shares of CIBM
Common Stock shall be issued in the Merger, and cash shall be paid by CIBM in
lieu of exchanging such fractional shares.

          (b)  The record holder of each share of CFSI Common Stock validly
issued and outstanding as of the Effective Date shall be converted into and
represent the right to receive CIBM Common Stock and cash (without interest
thereon) upon surrender of a certificate representing such share of CFSI Common
Stock as follows:

               (i)  for purposes of this Agreement, "CFSI Common Stock Exchange
Value" shall mean the per share book value of CFSI Common Stock calculated
pursuant to Section 1.6 of this Agreement multiplied by 1.68, and "CIBM Common
Stock Exchange Value" shall mean the per share book value of CIBM Common Stock
calculated pursuant to Section 1.6 of this Agreement multiplied by 1.75;

               (ii) the conversion ratio shall be determined by dividing the
CFSI Common Stock Exchange Value by the CIBM Common Stock Exchange Value (the
"Conversion Ratio");

               (iii) each holder of CFSI Common Stock shall receive shares of
CIBM Common Stock equal to the Conversion Ratio multiplied by the total number
of shares of CFSI Common Stock surrendered by such holder; and

               (iv) each holder of CFSI Common Stock who would otherwise receive
a fractional share of CIBM Common Stock will be paid cash in lieu of such
fractional share in an amount equal to the fractional share, multiplied by the
CIBM Common Stock Exchange Value.

          (c)  In the event the CFSI Common Stock Exchange Value is less than
 $9.50, CIBM may, in its sole discretion:

               (i)  terminate the Agreement;


<PAGE>   7

                                                                          PAGE 3


               (ii) substitute $9.50 as the CFSI Common Stock Exchange Value; or

               (iii) offer CFSI the CFSI Common Stock Exchange Value calculated
pursuant to Section 1.6 of this Agreement and CFSI shall have the option, in its
sole discretion, to accept the CFSI Common Stock Exchange Valueand complete the
Merger pursuant to the terms of this Agreement and the Plan of Merger or
terminate the Agreement.

Notwithstanding anything to the contrary in this Agreement, in the event this
Agreement is terminated pursuant to clause (i) or (iii), each party shall be
responsible for their respective costs and expenses incurred in the furtherance
of this Agreement and the transactions contemplated herein and none of the
parties shall have any further obligation or liability to the other except as
provided in Section 7.7 of this Agreement.

          (d)  Each holder of an option to acquire CFSI shares of common stock
which is vested, outstanding and exercisable pursuant to its terms at the
Effective Time, shall be converted into shares of CIBM common stock in an amount
equal to the difference between the CFSI Common Stock Exchange Value less the
per share exercise price, multiplied by a factor in which the numerator is equal
to the number of exercisable stock options held by the holder and the
denominator is the CIBM Common Stock Exchange Value . CIBM shall pay cash in
lieu of fractional shares. As a condition to the receipt of such shares of CIBM
common stock and cash in lieu of fractional shares, each option holder shall
execute a cancellation agreement in form and substance reasonably satisfactory
to CIBM.

     1.6  Per Share Book Value Calculation.

          (a)  The per share book value of CFSI and CIBM common stock shall be
calculated as of the close of business on the last day of the month prior to the
Closing Date (the "Valuation Date"). The per share book values of each CFSI and
CIBM shall be calculated by dividing the Base Capital of each CFSI and CIBM (as
hereinafter defined) by the number of their respective validly issued and
outstanding shares of common stock. Base Capital shall be the capital of CFSI
and CIBM, respectively, calculated in accordance with generally accepted
accounting principles in the United States of America ("GAAP"), subject to any
adjustments contemplated by Section 1.6(b) as of the Valuation Date.

          (b)  The following adjustments, as applicable, shall be made to the
capital of CFSI and CIBM to determine their respective Base Capital:

               (i)  professional fees not yet expensed or paid by CFSI in regard
to its Fairness Opinion, other transaction related expenses and any other
amounts due or to become due to its attorneys, accountants, advisors,
consultants or others related to the Merger shall be deducted from the capital
of CFSI;

               (ii) professional fees not yet expensed or paid by CIBM to its
attorneys, accountants, consultants or others related to the Merger shall be
deducted from the capital of CIBM;

               (iii) accounting and/or tax adjustments which relate to the
termination of the Citrus Bank 401(k) Plan shall be deducted from the capital of
CFSI;

               (iv) an amount equal to the total loan charge-offs within CFSI's
and the Bank's loan portfolio that would be made under CIBM's lending policies
and procedures shall be deducted, to the extent possible, from CFSI's and the
Bank's allowance for loan loss, with the remainder deducted from the capital of
CFSI;

               (v)  following any deduction from CFSI's and the Bank's allowance
for loan loss as provided in Section 1.6(b)(iv), an amount equal to the
difference between (A) one percent (1.0%) of the total loans of CFSI and the
Bank (excluding the charge-off loan amount calculated pursuant to Section
1.6(b)(iv)) and (B) the amount of the allowance for loan loss of CFSI and the
Bank, both

                                                                          PAGE 4

calculated as of the Valuation Date shall be deducted from the capital of CFSI,
provided that the amount calculated pursuant to (A) is greater than the amount
calculated pursuant to (B).

               (vi) all other adjustments to be made to the capital of CFSI and
CIBM as otherwise set forth in this Agreement.

     1.7  Exchange of Shares. Prior to or as soon as practicable after the
Effective Date, CIBM shall deposit or cause to be deposited with a bank or trust
company unaffiliated with CIBM (the "Exchange Agent"), for the benefit of the
holders of CFSI Common Stock, certificates representing the shares of CIBM
Common Stock and cash in lieu of any fractional shares (such cash and
certificates for shares of CIBM Common Stock collectively referred to herein as
the "Exchange Fund"), to be issued and paid pursuant to Section 1.6 in exchange
for the outstanding shares of CFSI Common Stock. The Exchange Agent shall invest
the cash portion of the Exchange Fund in a cash management vehicle acceptable to
CIBM, which may include a no-load money market fund.

          (a)  Promptly after the Effective Date, the Exchange Agent shall mail
a transmittal form, in form and substance reasonably satisfactory to CFSI, to
each holder of CFSI Common Stock (other than CIBM or CFSI) advising such holder
of the procedure for surrendering CFSI Common Stock share certificates to the
Exchange Agent for conversion into CIBM Common Stock certificates and/or payment
for a fractional share. After the Effective Date and upon the proper surrender
of a certificate evidencing shares of CFSI Common Stock, the Exchange Agent
shall deliver to the holder such shares of CIBM Common Stock pursuant to this
Agreement and the Plan of Merger, and a check, without interest thereon, in the
amount of cash for the fractional share to which the holder is then entitled
hereunder. The certificate of CFSI Common Stock so surrendered shall forthwith
be canceled.

          (b)  Notwithstanding anything to the contrary contained in this
Agreement, no certificates representing fractional shares of CIBM Common Stock
shall be issued upon the surrender for exchange of CFSI Common Stock
certificates, and no dividend or distribution with respect to CIBM Common Stock
shall be payable on or with respect to any fractional share, and such fractional
share interests shall not entitle the owner thereof to vote or to any other
rights of a stockholder of CIBM. Until so surrendered and exchanged, each CFSI
Common Stock certificate shall represent solely the right to receive the shares
of CIBM Common Stock and the cash for a fractional share calculated pursuant to
Section 1.5 into which it shall have been converted , and the Exchange Agent
shall not be required to transfer the shares or deliver to the holder thereof
the CIBM Common Stock and cash into which such certificate(s) shall have been
converted.

          (c)  No interest will be paid or accrued on any cash in lieu of
fractional shares. CIBM shall provide to the holders of CFSI Common Stock
procedures allowing for transfer of shares or payment with respect to lost or
destroyed certificates against receipt of customary and appropriate
certifications and indemnity.

          (d)  Any portion of the Exchange Fund that remains unclaimed by the

<PAGE>   11

                                                                          PAGE 7

Statements of Income prepared by CFSI for and at the three and twelve month
periods ended December 31, 2000 and for the interim period from January 1, 2001,
and ended through the last month prior to the Closing.

          (b)  The financial statements included or incorporated by reference
into the reports described in clause (a)(i) above are audited, comply with and
have been prepared in accordance with GAAP applied on a consistent basis, and,
together with the notes thereto, present fairly the financial position of CFSI
at the dates shown and the results of operations for the periods then ended. The
interim financial statements included in the reports described in clauses
(a)(ii) and (iii) or described in clause (a)(iv) are unaudited, comply with and
have been prepared in accordance with GAAP applied on a consistent basis, and
present fairly the financial position of the CFSI Entities.

          (c)  The books and records of the CFSI Entities accurately reflect the
financial condition of the CFSI Entities. The information contained in the CFSI
Financial Statements do not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements made therein not misleading. For the purpose of this clause and
Section 3.3(c), items are considered "material" regardless of size, if they
involve an omission or misstatement of accounting information that, in light of
surrounding circumstances, makes it probable that the judgment of a person
relying on the information would be changed or influenced by the omission or
misstatement.

     2.4  CFSI and Bank Reports. Since January 1, 1997, CFSI and the Bank have
timely filed all material reports, registrations and statements, together with
any amendments to be made with respect thereto required to be filed with (a) the
Federal Reserve Board, (b) the OCC, (c) the FDIC and (d) any other financial
institution regulatory authority (collectively the "CFSI Regulatory Reports").
CFSI and the Bank have paid all fees and assessments due and payable in
connection with the CFSI Regulatory Reports. As of their respective dates, such
CFSI Regulatory Reports complied in all material respects with the statutes,
rules and regulations in force or promulgated by the applicable regulatory
authority with which they were filed and did not contain any untrue statements
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, except that
information as of a later date shall be deemed to modify information as of an
earlier date. CFSI has provided to CIBM copies of all such reports,
registrations and statements. Except for normal examinations conducted by
regulatory agencies in the regular course of the businesses of CFSI and the
Bank, no regulatory agency has initiated any proceeding or, to the best
knowledge of CFSI no regulatory agency has indicated that it is considering
initiating an investigation into the businesses or operations of the CFSI
Entities since January 1, 1997, except where such proceedings or investigations
are not likely, either individually or in the aggregate, to have a Material
Adverse Effect (as defined in Section 7.8(a) of this Agreement)) on the CFSI
Entities. There is no material unresolved violations of laws or regulations of
any regulatory agency with respect to any report or statement relating to any
examinations of either of CFSI and the Bank. There are no payments of any sums
due and owing as a result of any violations of applicable regulations,
penalties, fines or assessments related thereto.

     2.5  SEC Reports. CFSI has provided to CIBM copies of each (a) final
registration statement, prospectus, report, schedule and definitive proxy
statement filed by CFSI with the Securities and Exchange Commission ("SEC")
pursuant to the Securities Act of 1933, as amended, and the Securities Exchange
Act of 1934, as amended (collectively the "Securities Acts") since January 1,
1997 (collectively the "CFSI SEC Filings") and (b) communication mailed by CFSI
to its shareholders since January 1, 1997, and no such registration statement,
prospectus, report, schedule, proxy, statement or communication contained any
untrue statement of a material fact or omitted to state any material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances in which they were made, not misleading.
As of their respective filing and effective dates, the filings of CFSI with the
SEC complied in all material respects with the published rules and regulations
of the SEC with respect thereto since January 1, 1997. CFSI has timely filed all
reports, registration statements and other documents required to be filed by it
under the Securities Acts.

     2.6  Insurance. Schedule 2.6 to this Agreement sets forth a summary of all
policies of insurance and bonds which are in full force and effect and in which
any of the CFSI Entities is named as an insured party (other than in its
capacity as a mortgagee), which otherwise relate to or cover any assets,
properties, premises, operations and personnel of the CFSI Entities or which is
owned or carried by any of the CFSI Entities. CFSI has had insurance in force
for the last five (5) years, which with respect to amounts, premiums, types and
risks insured, constitutes reasonably adequate coverage against all risks
customarily insured against by bank holding companies and their subsidiaries
comparable in size and operations to CFSI and its subsidiaries. Schedule 2.6
also describes any claims made or pending with regard to any policies and bonds
within the past five (5) years and neither CFSI nor the Bank is aware of any
facts which would form a basis of a claim under such bonds. The CFSI Entities
have in full force and effect policies of insurance and bonds issued by
reputable insurance companies against loss or damage of the kinds and in the
amounts identified in the policy summaries, and all premiums and costs with
respect thereto are set forth in Schedule 2.6. None of the CFSI Entities has
received notice from any party of interest in or to any such policies claiming
any breach or violation of any provisions thereof, disclaiming or denying any
coverage thereof, or canceling or threatening cancellation of any such insurance
contracts. Neither CFSI nor the Bank has any reason to believe that the existing
coverages would not be renewed by its carrier(s) on substantially the same
terms.

     2.7  Litigation and Compliance with Laws. The CFSI Entities and their
respective directors, officers, employees and controlling stockholders
(collectively, the "CFSI Entities Parties") are each in compliance in all
material respects with all applicable federal, state, county and municipal laws
and regulations that (a) regulate or are concerned in any way with the business
of banking or acting as a fiduciary, including those laws and regulations
relating to the investment of funds, the taking of deposits, the extension of
credit, the collection of interest, and the location and operation of banking
facilities, or (b) otherwise relate to or affect the business or assets of the
CFSI Entities or the assets owned, used, occupied or managed by any of them.
Except as disclosed in Schedule 2.7:

          (i)  there are no claims, actions, suits, orders, proceedings or
governmental or regulatory investigations pending, or, to the knowledge of CFSI,
threatened or contemplated against or affecting any of the CFSI Entities Parties
(in their capacities as such where applicable), at law or in equity, or before
any federal, state, municipal, administrative or other governmental authority or
court, or before any arbitrator or arbitration panel, whether by contract or
otherwise, which would have a Material Adverse Effect on CFSI; and

          (ii) there is no decree, judgment, order, supervisory agreement,
extraordinary supervisory letter, commitment letter, consent agreement or
memorandum of understanding entered into or in existence against or restraining
any of the CFSI Entities Parties from taking any actions of any kind in
connection with the business of any of the CFSI Entities, as the case may be.
None of the CFSI Entities Parties has been advised by, nor have any of them
received from any Regulatory Authority (as defined in Section 7.8(b) of this
Agreement) any notice or threat of enforcement actions or any criticism,
recommendation or suggestion of a material nature, and none of the CFSI Entities
has any basis for believing that any such notice or threat, criticism,
recommendation or suggestion not otherwise disclosed herein is contemplated.

     2.8  Conflict of Interest Transactions. Except as reflected in Schedule
2.8, no executive officer or director of any of the CFSI Entities, or holder of
10% or more of the common stock of CFSI, or any member of the immediate family
or related interest (as defined in 12 C.F.R. ss.215.2 (n)) of any such person:

          (a)  has any direct or indirect interest in (i) any entity which does
business with any of the CFSI Entities or (ii) any property or assets which is
owned or used by any of the CFSI Entities in the conduct of their business;

          (b)  has any financial, business or contractual relationships or

          (c)  has been involved in any transaction with any of the CFSI
Entities.

since December 31, 1999, which involves an amount in excess of $60,000, or has
had loans or any commitment to loan outstanding from any of the CFSI Entities in
excess of $60,000 not made in the ordinary course of business.

     2.9  Oral Commitments. To the best knowledge of CFSI, the records of the
Bank contain accurate copies of all contracts, commitments or arrangements of a
material nature, and the Bank has not entered into any such contract, commitment
or arrangement, not reduced to writing, in which it has agreed (a) to loan money
or extend credit, or to make other financial accommodations, to or for the
benefit of another party, (b) to waive, release, modify, extend or defer the
obligations or the terms thereof of any other party to repay indebtedness owing
to the Bank or to forbear in the enforcement of any right or remedy of the Bank
with respect thereto, (c) to release, relinquish or discharge any guarantor,
surety, or other party that is or may be liable for repayment of indebtedness
owing to the Bank, (d) to release or surrender, in whole or in part, any
collateral or rights therein, securing the obligation of any party that is or
may be liable for repayment of indebtedness owing to the Bank, or (e) to
purchase or sell, or repurchase or resell, any asset or interest or
participation therein from or to any party.

     2.10 Taxes. As used in this Agreement, the term "tax" or "taxes" means all
federal, state, county, local and foreign income, excise, gross receipts, ad
valorem, profits, gains, property, sales, transfer, use, payroll, employment,
severance, withholding, duties, intangibles, franchise, Social Security,
unemployment and other taxes, charges, levies or like assessments together with
all penalties and additions to tax and interest thereon.

          (a)  All tax returns, reports, declarations and information statements
required to be filed by any of the CFSI Entities with the United States or any
state or local government unit have been, and until the Closing will have been,
timely filed and are accurate and complete. No application for the extension of
time for filing any tax return or consent to any extension of time for filing
any tax return or consent to any extension of the period of limitations
applicable to the assessment or collection of any tax is in effect with respect
to any of the CFSI Entities. The CFSI Entities have each duly paid all taxes due
and none of the CFSI Entities is delinquent in the payment of any taxes due or
claimed to be due by any taxing authority and adequate provisions for taxes have
been made in the CFSI Financial Statements. None of the CFSI Entities has
received any notice of any proposed deficiency for any duty, tax, assessment or
governmental charge, and there are no pending claims with respect thereto. None
of the CFSI Entities is a member of any consolidated group other than CFSI for
purposes of the Internal Revenue Code of 1986 (the "Code"), as amended.

          (b)  Amounts withheld by the CFSI Entities from their employees for
all prior periods comply in all material respects with the tax withholding
provisions of applicable federal, state and local laws.

          (c)  There are no tax liens upon any property or assets of the CFSI
Entities.

          (d)  The Internal Revenue Service ("IRS") has not initiated or
proposed any adjustment or change in accounting method pursuant to Section 481
of the Code by reason of an involuntary change in accounting method by CFSI
which was included in income of the CFSI Entities. Except as set forth in the
CFSI Financial Statements, none of the CFSI Entities has entered into a
transaction which is being accounted for as an installment obligation under
Section 453 of the Code. Except as disclosed on Schedule 2.10, CFSI has not
requested or is considering to request a change in accounting method for the tax

ERISA Plan that is intended to be qualified under Section 401 and related
provisions of the Code is the subject of a determination letter from the IRS to
the effect that it is so qualified under the Code and its related funding
vehicle is tax-exempt, under Section 501 of the Code.

          (d)  No matter is pending relating to any CFSI Benefit Plan before any
court or governmental agency.

          (e)  None of the CFSI Entities is, or has ever been, obligated to
contribute to a multi-employer plan (as defined in Section 3(37) of ERISA).

Reconciliation Act of 1985 and Section 4980B of the Code or as reflected on
Schedule 2.22, none of the CFSI Entities,

                                                                         PAGE 12

nor any other party on behalf of any of the CFSI Entities, has any obligation or
commitment to provide health, disability or life insurance or similar welfare
benefits to former employees or members of their families.

          (g)  As of the Closing, each of the CFSI Benefit Plans shall be fully
funded and terminated or CFSI shall have applied for termination pursuant to
Section 4.18. For purposes of this Agreement, "fully funded" means all
contributions and other payments to be made by any of the CFSI Entities to any
CFSI Benefit Plan have been made or reserves adequate for such purposes have
been set aside therefore and reflected in the CFSI Financial Statements. None of
the CFSI Entities is in default in performing any of its respective obligations
under any of the CFSI Benefit Plans or any related trust agreement, insurance
contract or other agreement. There are no outstanding liabilities with respect
to any CFSI Benefit Plan.

          (h)  There is no litigation, claim or assessment pending or threatened
on behalf of or against any of the CFSI Benefit Plans that alleges a violation
of applicable state or federal law. CFSI knows of no basis for any such
litigation, claim or assessment.

     2.15 Undisclosed Liabilities. None of the CFSI Entities has any
liabilities, whether accrued, absolute, contingent or otherwise, and whether due
or to become due, existing or arising out of any transaction or state of facts
existing on or prior to the date hereof that, either alone or when combined with
all similar liabilities, has had, or could reasonably be expected to have, a
Material Adverse Effect on any of the CFSI Entities except (a) as fully
disclosed, reflected or reserved against in the consolidated balance sheet of
CFSI included in the CFSI June 30, 2000 Form 10-QSB, (b) as and to the extent
arising under contracts, commitments, transactions or circumstances identified
in this Agreement or the schedules or exhibits provided for herein, and (c) as
and to the extent incurred in the ordinary course of business consistent with
past practice since December 31, 1999.

     2.16 No Adverse Changes. Other than as specifically disclosed in this
Agreement, or as disclosed in the CFSI Financial Statements, and the CFSI SEC
Filings filed, prior to the date hereof, since December 31, 1999, none of the
CFSI Entities (a) has incurred any liability of any nature whatsoever (whether
absolute, accrued, contingent or otherwise and whether due or to become due)
that, either alone or when combined with all similar liabilities, had, or could
reasonably be expected to have, a Material Adverse Effect on CFSI, or (b) is
subject to any condition, event, circumstance, fact or occurrence (other than
changes resulting from or attributable to (i) changes in laws, regulations and

businesses, income, assets, liabilities, or financial condition of any of the
CFSI Entities.

     2.17 Conduct of Business in Normal Course. Since December 31, 1999, the
businesses of the CFSI Entities have been conducted only in the ordinary and
usual course consistent with past practice.

     2.18 Investment Securities. Each of the CFSI Entities has good and
marketable title to all securities held by it (except securities sold under
repurchase agreements or held in any fiduciary or agency capacity), free and
clear of any lien, except to the extent such securities are pledged in the
ordinary course of business consistent with prudent banking practices to secure
obligations of the CFSI Entities. Such securities are valued on the books of
CFSI in accordance with GAAP.

     2.19 Properties and Assets.

          (a)  Schedule 2.19(a) to this Agreement sets forth a complete and
correct description of all real property owned or leased by the CFSI Entities or
in which any of them has an interest (other than as a mortgagee), including all
real property carried by the Bank as other real estate owned ("OREO"). The CFSI
Entities own or have a valid right to use, or a valid leasehold interest in, all
real property used by them in the conduct of their respective businesses as such
businesses are now being conducted, subject to no mortgage, pledge, lien,
option, conditional sale agreement, encumbrance, security interest, title
exceptions, restrictions, claim or charge of any kind except as set forth on
Schedule


<PAGE>   17

                                                                         PAGE 13

2.19(a). All material certificates, licenses and permits required for the lawful
use and occupancy of such real property by any of the CFSI Entities, as the case
may be, have been obtained and are in full force and effect. Except as otherwise
disclosed on Schedule 2.19(a), all real property carried by the Bank as Other
Real Estate Owned ("OREO") is the subject of a recent appraisal which complies
with applicable regulatory requirements and is carried on the Bank's books at an
amount that has been calculated in accordance with GAAP and applicable
regulatory guidelines.

          (b)  Schedule 2.19(b) to this Agreement sets forth a complete and
correct description of each item of personal property which had an original cost
equal to or greater than $10,000 that is owned or leased by any of the CFSI
Entities and used in the conduct of their respective businesses. Except as
disclosed on Schedule 2.19(b), all said personal property owned by the CFSI
Entities, or used by any of them in their businesses, are owned free and clear
of any liens, claims, encumbrances or rights of others and all of said assets
are in good working condition, normal wear and tear excepted. The assets
reflected in the most recent CFSI Financial Statements or identified in this
Agreement or the schedules provided for herein include (a) all of the assets
owned by any of the CFSI Entities, except for those subsequently disposed of by
the CFSI Entities for fair market value in the ordinary course of business, and
(b) all of the assets used or intended for use by any of the CFSI Entities in
the conduct of their respective businesses.

     2.20 Other Property Interests. Schedule 2.20 to this Agreement sets forth a
complete and correct description of all real estate which is the subject of
pending foreclosure proceedings by any of the CFSI Entities, otherwise not
included in Schedule 2.19(a), indicating in each case whether such real estate
is improved and the nature of any material encumbrances, defects of title or
environmental conditions of which CFSI has knowledge.

     2.21 Loan Portfolio. Except as disclosed on Schedule 2.21, the loans
contained in the loan portfolio of the Bank are evidenced by promissory notes or
other evidences of indebtedness, which, with all ancillary security documents,
constitute valid and binding obligations of the Bank and each of the other
parties thereto, enforceable in accordance with their terms, except as limited
by applicable bankruptcy, insolvency, moratorium or other similar laws affecting
the enforcement of creditors' rights and remedies generally and by applicable
laws or principles of equity which may affect the availability of equitable
remedies. None of such loans is subject to any defense, set-off or counterclaim
of any party liable thereon and all such loans which are secured, as evidenced
by the ancillary security documents, are so secured by valid and enforceable
liens. The Bank's reserve for loan losses has been calculated in accordance with
prudent and customary banking practices and is adequate to reflect the risk
inherent in the Bank's loan portfolio.

     2.22 Significant Contracts. Schedule 2.22 sets forth a Schedule which
completely and accurately lists or describes, and includes a copy of the
following contracts, commitments or arrangements (whether written or oral) under

ordinary and customary banking relationships that comply with applicable banking
regulations; and

          (h)  all other contracts to which any of the CFSI Entities is a party
or under which any of the CFSI Entities is obligated, other than in the usual or
ordinary course of business of any of the CFSI Entities, which involves the
payment by any of the CFSI Entities of more than $5,000.

Except as disclosed on Schedule 2.22, and except with regard to loans made by
any of the CFSI Entities in the ordinary course of their respective businesses,
there are no other material contracts, commitments or arrangements (whether
written or oral) under which any of the CFSI Entities is obligated wherein the
aggregate commitment of any of the CFSI Entities, individually or jointly,
exceeds $5,000.

     2.23 No Defaults. All contracts, commitments or arrangements of any of the
CFSI Entities set forth on Schedule 2.22 to this Agreement are valid and in full
force and effect. Each of the CFSI Entities have fulfilled and taken all action
reasonably necessary to date to enable it to fulfill, when due, all material
obligations under all contracts, commitments and arrangements to which it is a
party. There are no defaults under any such contracts, commitments and
arrangements, and no events have occurred that, with the lapse of time or
election of any other party, will become defaults by any of the CFSI Entities
which would have a Material Adverse Effect on CFSI. No breach or default by any
other party under such contracts, commitments or arrangements has occurred or is
threatened that will or could impair the ability of the CFSI Entities to enforce
any of their rights thereunder in any material respect.

     2.24 No Fiduciary Powers. None of the CFSI Entities has obtained from

CFSI has provided CIBM such other documents relating to the authority of the
CFSI Entities to conduct their businesses as CIBM has requested. All such
documents are true, complete and correct copies of the original documents. The
stock registers and minute books of the CFSI Entities to the extent they exist,
access to which have been provided to CIBM, are complete and correct in all
material respects and accurately reflect all meetings, consents and other
actions of the organizers, incorporators, shareholders and stockholders (as the

CFSI Entities and all transactions in the capital stock of the CFSI Entities,
occurring since their organization.

representative or supplier intends to discontinue, diminish, or change its

Materially Adverse Effect on the business of any of the CFSI Entities, or (b)
that any officer of any of the CFSI Entities intends to terminate or

2.28.

     2.29 No Exercise. Since November of 1998, there have been no cashless

<PAGE>   21

                                                                         PAGE 17

respect thereto required to be filed with (a) the Federal Reserve Board, (b) the
OTS, (c) the FDIC and (d) any other financial institution regulatory authority
(collectively the "CIBM Regulatory Reports"). CIBM and the CIBM Banks have paid
all fees and assessments due and payable in connection with the CIBM Regulatory
Reports. As of their respective dates, such CIBM Regulatory Reports complied in
all material respects with the statutes, rules and regulations in force or
promulgated by the applicable regulatory authority with which they were filed
and did not contain any untrue statements of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except that information as of a later date shall be deemed to modify
information as of an earlier date. CIBM has made available to CFSI copies of all
such requested reports, registrations and statements. Except for normal
examinations conducted by regulatory agencies in the regular course of the
businesses of CIBM and the CIBM Banks, no regulatory agency has initiated any
proceeding or, to the best knowledge of CIBM no regulatory agency has indicated
that it is considering initiating an investigation into the businesses or
operations of CIBM and the CIBM Banks since January 1, 1997, except where such
proceedings or investigation are not likely, either individually or in the
aggregate to have a Material Adverse Effect on CIBM. There is no material
unresolved violations of laws or regulations of any regulatory agency with
respect to any report or statement relating to any examinations of either of
CIBM and the CIBM Banks. There are no payments of any material sums due and
owing as a result of any violations of applicable regulations, penalties, fines
or assessments related thereto.

     3.5  SEC Reports. CIBM has filed all reports, registration statements and
other documents, or any amendments thereto required to be filed with the SEC
under the rules and regulations of the SEC, and all such reports, registration
statements and other documents have complied in all material respects, as of
their respective filing dates and effective dates, as the case may be, with all
applicable requirements of the Securities Acts. Unless otherwise amended, as of
their respective filing and effective dates, none of such reports, registration
statements or other documents contained any untrue statement of a material fact
or omitted to state a material fact required to be stated therein or necessary
in order to make the statements therein, in light of the circumstances under
which they were made, not misleading, except that information as of a later date
shall be deemed to modify information as of an earlier date. CIBM has timely
filed all reports, registration statements and other documents required to be
filed by it under the Securities Act.

     3.6  Insurance. Schedule 3.6 to this Agreement sets forth a summary of all
policies of insurance and bonds which are in full force and effect and in which
any of CIBM and the CIBM Banks is named as an insured party (other than in its
capacity as a mortgagee), which otherwise relate to or cover any assets,
properties, premises, operations and personnel of CIBM and the CIBM Banks or
which is owned or carried by any of CIBM or the CIBM Banks. CIBM has had
insurance in force for the last five (5) years, which in respect to amounts,
premiums, types and risks insured, constitutes reasonably adequate coverage
against all risks customarily insured against by bank holding companies and
their subsidiaries comparable in size and operations to CIBM and its
subsidiaries. The CIBM Entities have in full force and effect policies of
insurance and bonds issued by reputable insurance companies against loss or
damage of the kinds and in the amounts identified in the policy summaries, and
all premiums and costs with respect thereto are set forth in Schedule 3.6. None
of CIBM or the CIBM Banks has received notice from any party of interest in or
to any such policies claiming any breach or violation of any provisions thereof,
disclaiming or denying any coverage thereof, or canceling or threatening
cancellation of any such insurance contracts. Neither CIBM nor the CIBM Banks
has any reason to believe that the existing coverages would not be renewed by
its carrier(s) on substantially the same terms.

     3.7  Litigation and Compliance with Laws. The CIBM Entities and their
respective directors, officers, employees and controlling stockholders
(collectively the "CIBM Entities Parties") are each in compliance in all
material respects with all applicable federal, state, county and municipal laws
and regulations that (a) regulate or are concerned in any way with the business
of banking or acting as a fiduciary, including those laws and regulations
relating to the investment of funds, the taking of deposits, the extension of
credit, the collection of interest, and the location and operation of banking
facilities, or (b) otherwise relate to or affect the business or assets of the
CIBM Entities or the assets owned, used, occupied or managed by any of them.

          (i)  there are no claims, actions, suits, orders, proceedings or
governmental or regulatory investigations pending, or, to the knowledge of CIBM,
threatened or contemplated against or affecting the CIBM Entities Parties (in
their capacities as such where applicable), at law or in equity, or before any
federal, state, municipal, administrative or other governmental authority or
court, or before any arbitrator or arbitration panel, whether by contract or
otherwise which to the best knowledge of CIBM would have a Material Adverse
Effect on CIBM; and

          (ii) there is no decree, judgment, order, supervisory agreement,
extraordinary supervisory letter, commitment letter, consent agreement or
memorandum of understanding entered into or in existence against or restraining
any of the CIBM Entities Parties, from taking any actions of any kind in

None of the CIBM Entities has been advised by, nor have any of them received
from any Regulatory Authority any notice or threat of enforcement actions or any

criticism, recommendation or suggestion not otherwise disclosed herein is
contemplated.

will or could impair the ability of the CIBM Entities to enforce any of their
rights thereunder in any material respect.

promptly advise CFSI and its counsel of any substantive communication received
by CIBM or its counsel from the SEC with respect to the Registration Statement.

the Registration Statement, the Proxy Statement, or any other document filed
with the SEC or any state securities commission, at the respective times at
which such documents are filed with the SEC or such state securities commission,
or, in the case of the Registration Statement, when it becomes effective, or, in
the case of the Proxy Statement, when mailed or at the time of the Shareholders

to accomplish any of the foregoing, except (a) upon the termination of this
Agreement pursuant to Section 7.4 of this Agreement; (b) with the prior written
consent of CIBM; (c) pursuant to a written direction from any Regulatory
Authority; or (d) upon CFSI receiving an unsolicited bonafide offer from a third
party where the Board of Directors of CFSI reasonably believes, after

it to enter into discussions with such party. The Board of Directors of CFSI and
any committee thereof shall not withdraw or modify their approval recommendation
of the transactions contemplated by this Agreement and the Plan of Merger, or

and assets of the other party that may have been obtained in the course of
negotiations or examination of the affairs of the other party either prior or
subsequent to the execution of this Agreement (other than such information as
shall be in the public domain or otherwise ascertainable from public, or other
sources that are not bound by confidentiality obligations in favor of CFSI or
CIBM).

     4.15 Maintenance of Capital Levels. CIBM and CFSI, and their respective
subsidiaries, shall maintain at least the minimum capital levels as required by
Regulatory Authorities.

     4.16 No Control of CFSI by CIBM. Other than as set forth in this Agreement,
until the Effective Date, the management of the CFSI Entities and the authority
to establish and implement their business policies shall reside solely in the
CFSI Entities' officers and Boards of Directors.

     4.17 Employees.

          (a)  All wages, accrued but unpaid bonuses, accrued vacation time and
all other accrued and vested benefits of the employees of the CIBM Entities and

A. Alvarez and deferred commissions due to William Schuh, shall be, prior to the

assistance to CIBM in regard to continuing the employment of any of the CFSI
Entities' employees.

          (a)  Prior to the Effective Date, CFSI shall take all necessary action
to terminate the Citrus Bank 401(k) Plan and upon termination of the Citrus Bank
401(k) Plan, all participants thereunder (the "Plan Participants") shall fully
vest. Within thirty (30) days of this Agreement, in anticipation of such
termination, CFSI shall apply for and use their best efforts to obtain a letter
from the IRS as to the tax qualified status of the Citrus Bank 401(k) Plan upon
its termination (the "Final Determination Letter"). Prior to the Closing, the
Citrus Bank 401(k) Plan shall be fully funded and no further contribution
thereto shall be required by CFSI or CIBM.

          (b)  In the event that CFSI prior to the Effective Date, and CIBM
after the Effective Date, reasonably determine that the 401(k) Plan cannot
obtain a favorable Final Determination Letter, or that the amounts held therein
cannot be so applied, allocated or distributed without causing the Citrus Bank
401(k) Plan to lose its qualified status, CFSI prior to the Effective Date and
CIBM after the Effective Date shall take such action as they may reasonably
determine with respect to the distribution of benefits to the Plan Participants,
provided that the assets of the Citrus Bank 401(k) Plan shall be held or paid
for the benefit of the Plan Participants and further that in no event shall any
portion of the amounts held in the Citrus Bank 401(k) Plan revert directly or
indirectly to CFSI or any affiliate thereof, or to CIBM or any affiliate
thereof.

     4.19 Directors' and Officers' Liability Insurance. Prior to the Closing
Date, CFSI shall assist CIBM in purchasing single (one-time) premium tail
directors' and officers' liability insurance coverage, covering the employees,
directors and officers of all the CFSI Entities (of at least the same coverage
and amounts, and containing terms which are not materially less advantageous
than the directors' and officers' liability insurance policy in force on the
date of this Agreement and more fully described on Schedule_2.6 of this
Agreement) for four (4) years from the Effective Date for present and former
directors and officers for matters existing or occurring prior to, at or after
the Effective Date (the "Tail Insurance"). CIBM shall pay seventy-five percent
(75%) of the cost of the Tail Insurance and CFSI shall pay twenty-five percent
(25%) of the cost of the Tail Insurance.

     4.20 Boards of Directors of the CFSI Entities. At the Closing, CFSI shall
deliver to CIBM resignations of all Directors of the CFSI Entities, except those
specifically set forth in the Plan of Merger or as identified by CIBM prior to
the Closing. The letters of resignation shall be in a form acceptable to CIBM
and shall contain releases of liability as required by CIBM.

     4.21 Accruals. All costs and expenses reasonably estimated to be incurred
by the CFSI Entities and the CIBM Entities, including all professional fees,
costs and expenses payable to the CFSI Entities' and the CIBM Entities'
respective attorneys, accountants, agents, consultants and advisors relative to
this transaction, shall be paid or accrued on or prior to the Valuation Date and
be properly recorded on the applicable books and records of the CFSI Entities
and the CIBM Entities.

     4.22 Untrue Representations and Warranties. During the term of this
Agreement, if any party becomes aware of any facts or of the occurrence or
impending occurrence of an event which would cause one or more of the
representations and warranties of such party contained in this Agreement to be
or become untrue as of the Closing Date, then:

          (a)  such party shall immediately give detailed written notice thereof
to the other party; and

          (b)  such party shall use reasonable efforts to change such facts or
events to make such representations and warranties true, unless the same shall
have been waived by the other party in writing.

     4.23 Shareholder List. Immediately prior to the mailing of the Proxy
Statement, CFSI shall make available to CIBM its list of shareholders, including
the name and address of each shareholder and the number of shares of Common
Stock of CFSI held by each shareholder, including shares owned beneficially by
each such shareholder. Except as otherwise provided in this Agreement, CIBM
shall not independently solicit the shareholders of CFSI prior to the Closing
relative to the merits of this transaction.

     4.24 Shareholder Voting Agreement. Contemporaneously with the execution of
this Agreement, CFSI shall deliver to CIBM a Shareholder Voting Agreement,
substantially in the form of Exhibit C-1 or C-2 (for any shareholder who is the

per share of CIBM Common Stock or CIBM Preferred Stock calculated as of the last
day of the month preceding the offering, or through the exercise of options by
option holders pursuant to the terms of the option agreements. CIBM may also, in
its sole discretion, grant options to directors, officers and employees
consistent with past practices and, with shareholder approval, amend the CIB
Marine Bancshares, Inc. Stock Option and Incentive Plan to increase the number
of shares subject to the plan to no more than twelve and one-half percent
(12.5%) of the total issued and outstanding shares of CIBM Common Stock.

     4.26 Dividends. CIBM shall not declare a dividend (stock, cash or
otherwise) between the Valuation Date and the Effective Date.

     4.27 Employees. CIBM shall allow such employees of CFSI and the Bank who
remain in the employ of CFSI and the Bank after the Effective Date to

counsel for CFSI, dated as of the Closing Date, and in form and substance
satisfactory to CIBM and its counsel to the effect that:

               (i)  CFSI is a corporation validly existing under the laws of the
State of Florida. CFSI is registered as a bank holding company under the BHC

               (ii) The Bank is a validly existing commercial bank under the
laws of the United States.

               (iii) CRC and CMC are validly existing corporations under the

the requisite vote of such shareholders under CFSI's Articles of Incorporation,
its Bylaws and applicable Florida law, these being the only authorizations
required under its Articles of Incorporation, its Bylaws, and the statutes of

               (vii) To the best of counsel's knowledge, there are no material
claims, actions, suits, or proceedings pending or threatened against the CFSI

expected to have a Material Adverse Effect on either of the CFSI Entities.

               (viii) To the best knowledge of counsel, there are no actions,
suits or proceedings pending or threatened against any of the CFSI Entities to
enjoin consummation of the Merger or to obtain other relief (other than payment

Merger, or the transactions contemplated hereby or thereby.

In rendering the foregoing opinion, such counsel may rely on certificates of
corporate officers or governmental officials as to factual matters.

          (h)  No Adverse Changes. Between the date of this Agreement and the
Closing Date, the businesses of the CFSI Entities shall have been conducted in
the ordinary course consistent in all material respects with prudent banking
practices, and there shall not have occurred any material adverse change or any

Effect on the CFSI Entities' respective businesses, prospects, income, assets,
liabilities or financial condition. None of the CFSI Entities shall have been
made a party to, or threatened with any actions, suits, proceedings or

other properties or facilities in which any of the CFSI Entities has any
interest (either individually or as a fiduciary) as identified by CIBM,
conducted by an independent environmental consultant reasonably acceptable to
CIBM. CFSI shall pay the cost of obtaining such Phase I environmental audits. No
such environmental audit shall have identified any violation of the

          (f)  No Litigation. No suit or other action shall have been instituted
or threatened seeking to enjoin the consummation of the transactions
contemplated hereby or by the Plan of Merger, or to obtain other relief in
connection with this Agreement or the transactions contemplated hereby or
thereby (including, but not limited to, substantial damages) which reasonably

regulation, order, injunction or decree shall have been enacted, entered,

          (g)  Opinion of Counsel. CFSI shall have received the opinion of
counsel for CIBM and CIBMAC, dated as of the Closing Date, in form satisfactory
to CFSI and its counsel to the effect that:

               (i)  CIBM is a corporation validly existing under the laws of the
State of Wisconsin. CIBM is registered as a bank holding company under the BHC
Act.

               (ii) CIBMAC is a validly existing corporation under the laws of
the State of Florida.

               (iii) The execution, delivery, and performance of this Agreement,
and the Plan of Merger, and the transactions contemplated herein and therein
have been duly authorized by the Board of Directors of CIBM and the sole
shareholder of CIBMAC, these being the only authorizations required under their
Articles of Incorporation, Bylaws, and the statutes of the State of Florida. The
Agreement and the Plan of Merger constitute the legal, valid and binding
obligations of CIBM and CFSI enforceable in accordance with their respective
terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium
or similar laws affecting creditors generally and to general principles of
equity.

               (iv) The execution, delivery and performance of this Agreement
and the Plan of Merger do not violate any provisions of the Articles of
Incorporation or Bylaws of CIBM or any material contract or agreement known to
counsel by which CIBM is bound or any law, rule, regulation or, to counsel's
knowledge, written order to which CIBM is subject.

               (v)  The execution, delivery and performance of the Plan of
Merger do not violate any provisions of the Articles of Incorporation or Bylaws
of CIBMAC or any material contract or agreement known to counsel by which CIBMAC
is bound or any law, rule, regulation or, to counsel's knowledge, written order
to which CIBMAC is subject.

               (vi) To the best of counsel's knowledge, there are no material
claims, actions, suits or proceedings pending or threatened against CIBM or
CIBMAC which depart from the ordinary, routine litigation incident to the kind
of business carried on by CIBM or CIBMAC which might reasonably be expected to
have a Material Adverse Effect on CIBM or CIBMAC.

               (vii) To the best knowledge of counsel, there are no actions,
suits or proceedings pending or threatened against CIBM or CIBMAC to enjoin
consummation of the Merger or to obtain other relief (other than payment to
dissenting shareholders) in connection with this Agreement, the Plan of Merger,
or the transaction contemplated hereby or thereby.

In rendering the foregoing opinion, such counsel may rely on certificates of
corporate officers or governmental officials as to factual matters.

          (h)  No Adverse Changes. Between the date of this Agreement and the
Closing Date, the businesses of the CIBM Entities shall have been conducted in
the ordinary course consistent in all material respects with prudent banking
practices, and there shall not have occurred any material adverse change or any
condition, event, circumstance, fact or occurrence (other than general economic
or competitive conditions) that may be expected to result in a Material Adverse
Effect on the CIBM Entities' respective businesses, prospects, income, assets,
liabilities or financial condition. None of the CIBM Entities shall have been
made a party to, or threatened with any actions, suits, proceedings or
litigation which, in the opinion of CFSI, will have or is likely to have a
Material Adverse Effect on the respective financial condition, assets or
businesses of the CIBM Entities.

          (i)  Other Documents. CFSI shall have received at the Closing all such
other documents, certificates or instruments as it may have reasonably requested
evidencing compliance by CIBM with the terms of this Agreement.

pursuant to Section 5.1(j) of this Agreement, CFSI shall have received from KPMG
LLP and Stevens, Sparks & Co., P.A. "Comfort Letters" dated the date of mailing
of the Proxy Statement covering matters customary to transactions such as the
Merger.

          (k)  Fairness Opinion. David A. Noyes & Company shall have delivered
to the Board of Directors of CFSI a fairness opinion in form and substance
reasonably satisfactory to CFSI, updated as of a date approximately the date of
mailing of the Proxy Statement,the opinion that the Merger is fair from a
financial point of view to the shareholders of CFSI.

     7.1  Further Assurances. Each of the parties hereto agrees that at any time

     7.2  Expenses. Each of the parties to this Agreement shall bear the costs
and expenses incurred by it in connection with this Agreement and the
transactions contemplated hereby; provided, however, that:

          (i)  in the event this Agreement is terminated by CIBM solely because

verification thereof, it has incurred in furtherance of this Agreement and the
transactions contemplated herein, including, but not limited to, reasonable fees
of professionals engaged for such purpose by or on behalf of CIBM, provided
that, notwithstanding any other provision of this Agreement, neither CFSI nor
CIBM shall be required to pay the other for reimbursement of expenses incurred

this Agreement is terminated by CIBM solely because Section 5.1(m) has not been

     7.3  Successors and Assigns. This Agreement shall be binding upon and inure
to the benefit of the respective heirs, successors, assigns and personal
representations of the parties hereto; provided, however, that no party may

made by the other party in the observance or in the due and timely performance

twenty (20) days, after written notice

                                                                         PAGE 36

specifying the alleged default shall have been given; or (e) by CFSI if the
Board of Directors after consultation with counsel determines that its fiduciary
duties require it to accept an unsolicited offer from a third party and CFSI
shall have delivered to CIBM an opinion of counsel to such effect and CIBM shall
have elected not to exercise its right of first refusal pursuant to Section 7.5
hereof. Notwithstanding anything contained in this Section 7.4 to the contrary,
neither CIBM or CFSI shall be entitled to collect expenses under Section 7.2 if
at the time such party is in material breach of any of its representations,
warranties, covenants or agreements.

     7.5  Right of First Refusal.

          (a)  In the event that prior to the consummation of the transactions
contemplated by this Agreement the CFSI Board of Directors receives an
unsolicited third party offer to (i) acquire beneficial or record ownership of
at least a majority of the outstanding shares of CFSI Common Stock, (ii) acquire
all or substantially all of any of the CFSI Entities assets, or (iii) engage in
a merger, consolidation, recapitalization or other business combination with
such third party, CFSI shall deliver to CIBM written notice of such proposed
acquisition which shall contain a description of the principal terms of the
proposed acquisition (the "Proposal"), including the purchase price (payment of
which shall be subject only to satisfaction of customary closing conditions and
the receipt of all necessary regulatory approvals), the time and place of
closing of such acquisition, and all other material terms of the proposed
acquisition. Within thirty (30) days after delivery of the Proposal, CIBM shall
notify CFSI as to whether or not it intends to exercise its right of first
refusal set forth in clause (b). In the event a Proposal contains purchase price
consideration other than cash and CFSI and CIBM cannot agree upon the
appropriate stock or cash equivalent, CFSI and CIBM shall select an investment
banker mutually agreeable to each of them for purposes of valuing any non-cash
consideration contained in the Proposal. CFSI and CIBM shall each pay one-half
of the fees and expenses of any such investment banker.

          (b)  For a period of 30 days after delivery of the Proposal (or such
longer time period as may be required to obtain all necessary regulatory
approvals or, with respect to any financial commitments CIBM requires to
consummate the acquisition, such longer period as shall be reasonably necessary
and negotiated by the parties), CIBM shall have the sole and exclusive right to
acquire CFSI for the consideration and on such other terms and conditions stated
in the Proposal (or in the case of noncash consideration, as determined in the
manner described in clause (a)). In the event CIBM determines not to exercise
its right of first refusal hereunder, CIBM shall remain entitled to the remedies
set forth in Section 7.2 and 7.6 hereof in accordance with the terms thereof.

     7.6  Cancellation Fee. In the event CFSI terminates the Agreement pursuant
to Section 7.4(e), CFSI shall make a cash payment to CIBM in an amount equal to
$500,000. The cancellation fee set forth herein shall be in addition to any
expenses CFSI is obligated to pay to CIBM under Section 7.2 of this Agreement.

     7.7  Loan Put Agreement. In the event this Agreement is terminated pursuant
to Section 1.5(c)(i) or (iii), Section 7.4(a) or (b), or by CFSI pursuant to
Section 7.4(c) or (d), CFSI shall have the option to put to CIBM any and all
loans made after the date of this Agreement by CFSI or the Bank that had an
original principal amount of $25,000 or more provided that: (a) CFSI shall have
provided to CIBM all information reasonably requested by CIBM to approve or
disapprove of each such loan; (b) CIBM shall have consented in writing to the
making of each such loan by CFSI or the Bank; (c) each such loan is evidenced by
promissory notes or other evidences of indebtedness, which, with all ancillary
security documents, constitute valid and binding obligations of the Bank and
each of the other parties thereto, enforceable in accordance with their terms,
except as limited by applicable bankruptcy, insolvency, moratorium or other
similar laws affecting the enforcement of creditors' rights and remedies
generally and by applicable laws or principles of equity which may affect the
availability of equitable remedies; (d) none of such loans is subject to any
defense, set-off or counterclaim of any party liable thereon and all such loans
which are secured, as evidenced by the ancillary security documents, are so
secured by valid and enforceable liens; (e) each such loan is assignable under
applicable law; and (f) CFSI shall have identified in writing within five (5)
business days after the date of the termination of this Agreement ("Put Notice")
all such loans that CFSI and the Bank shall put to CIBM. CIBM shall purchase all
such loans

                                                                         PAGE 37

properly put to CIBM on a date no more than ten (10) days after receipt of the
Put Notice ("Purchase Date") for an amount equal to the outstanding principal
balance of the loan plus accrued interest as of the Purchase Date less any loan
origination or similar fees received by CFSI or the Bank. CFSI and the Bank
shall assign and transfer and deliver to CIBM all promissory notes, evidences of
indebtedness, security agreements and all other loan documents of CFSI and the
Bank relating to each such loan and CFSI and the Bank shall make, execute and
deliver all documents required by CIBM to assign and transfer such loans to

                                   ARTICLE III
                   TERMS OF CONVERSION AND EXCHANGE OF SHARES

     3.1  Treatment of Shares. On the Effective Date, by virtue of the Merger
and without any action on the part of the holder of any share of CIBMAC Common
Stock or any share of CFSI Common Stock, the following shall occur:

          (a)  each share of $1.00 par common stock of CIBMAC issued and
outstanding immediately prior to the Effective Date shall be converted into one
validly issued, fully-paid and nonassessable share of the common stock of CFSI.

          (b)  All validly issued and outstanding shares of CFSI Common Stock on
the Effective Date shall be converted, by virtue of the Merger, into such number
of shares of the common stock of CIBM, par value $1.00 per share (the "CIBM
Common Stock"), and cash as follows:

               (i)  For purposes of this Plan of Merger, "CFSI Common Stock
Exchange Value" shall mean the per share book value of CFSI Common Stock
calculated pursuant to Sections 3.1(c) and (d) of this Plan of Merger multiplied
by 1.68, and "CIBM Common Stock Exchange Value" shall mean the per share book
value of CIBM Common Stock calculated pursuant to Section 3.1(c) and (d) of this
Plan of Merger multiplied by 1.75;

               (ii) the conversion ratio shall be determined by dividing the
CFSI Common Stock Exchange Value by the CIBM Common Stock Exchange Value (the
"Conversion Ratio");

                                                                          PAGE 4

               (iii) each holder of CFSI Common Stock shall receive shares of
CIBM Common Stock equal to the Conversion Ratio multiplied by the total number
of shares of CFSI Common Stock owned directly or beneficially by such holder;
and

               (iv) each holder of CFSI Common Stock who would otherwise receive
a fractional share of CIBM Common Stock will be paid cash in lieu of such
fractional share in an amount equal to the fractional share, multiplied by the
CIBM Common Stock Exchange Value.

          (c)  The per share book value of CFSI and CIBM common stock shall be
calculated as of the last day of the month prior to the Closing Date. The per
share book values of each CFSI and CIBM shall be calculated by dividing the Base
Capital of each CFSI and CIBM (as hereinafter defined) by the number of their
respective validly issued and outstanding shares of common stock. Base Capital
shall be the capital of CFSI and CIBM, respectively calculated in accordance
with generally accepted accounting principles ("GAAP") as of the last day of the
month prior to the Closing Date and any adjustments contemplated by Section
3.1(d).

          (d)  No more than five (5) business days prior to the Closing Date,
there shall commence an investigatory period during which CIBM and CFSI shall
have an opportunity to conduct a review of the books and records of each other
for the purpose of making the following adjustments to the capital of the other,
as the case may be:

               (i)  professional fees not yet expensed or paid by CFSI in regard
to its Fairness Opinion, other transaction related expenses and any other
amounts due or to become due to its attorneys, accountants, advisors,
consultants or others related to the Merger shall be deducted from the capital
of CFSI;

               (ii) professional fees not yet expensed or paid by CIBM to its
attorneys, accountants, advisors, consultants or others related to the Merger
shall be deducted from the capital of CIBM;

               (iii) accounting and/or tax adjustments which relate to the
termination of the Citrus Bank 401(k) Plan shall be deducted from the capital of
CFSI;

               (iv) an amount equal to the total loan charge-offs within CFSI's
and the Bank's loan portfolio that would be made under CIBM's lending policies
and procedures shall be deducted, to the extent possible, from CFSI's and the
Bank's allowance for loan loss, with the remainder deducted from the capital of
CFSI;

               (v)  following any deduction from CFSI's and the Bank's allowance
for loan loss as provided in Section 3.1(d)(iv), an amount equal to the
difference between (A) one percent (1.0%) of the total loans of CFSI and the
Bank (excluding the charge-off loan amount calculated pursuant Section
3.1(d)(iv)) and (B) the amount of the allowance for loan loss of CFSI and the
Bank, both calculated as of the Valuation Date, shall be deducted from the
capital of CFSI, provided that the amount calculated pursuant to (A) is greater
than the amount calculated pursuant to (B).

               (vi) all other adjustments to be made to the capital of CFSI and
CIBM as otherwise set forth in this Agreement.

          (e)  Each share of CFSI Common Stock held by CFSI as treasury stock
shall be canceled and shall cease to exist, and no consideration shall be paid
or delivered in exchange therefore under this Plan of Merger.

          (f)  Each issued and outstanding share of CFSI Common Stock, the
holders of which have validly asserted dissenters' rights pursuant to Sections
607.1302 and 607.1320 of the FBCA, and shall not have effectively withdrawn or
lost such right to receive payment of the fair value of his or her shares of
CFSI Common Stock, shall not be converted into or represent a right to receive
the consideration specified in subparagraph (b) of this Section 3.1, but the
holder thereof shall be entitled only to such rights as are granted by Sections
607.1302 and 607.1320. Each shareholder who becomes entitled, pursuant to the
provisions of Sections 607.1302 and 607.1320, to payment for his or her shares
of CFSI Common Stock, shall receive payment therefor from the Surviving
Corporation (but only after the amount thereof shall have been agreed upon or
finally determined pursuant to such provisions), and such CFSI Common Stock
shall be canceled.

          (g)  If any holder of shares of CFSI common stock who asserts
dissenters' rights under Sections 607.1302 and 607.1320 shall effectively
withdraw or lose (through failure to perfect or otherwise) his or her
dissenters' rights, each such share of CFSI Common Stock shall be converted into
the right to receive the consideration specified in Section 3.1(b).

          (h)  Each holder of an option to acquire CFSI shares of common stock
which is vested, outstanding and exercisable pursuant to its terms at the
Effective Time, shall be converted into shares of CIBM common stock in an amount
equal to the difference between the CFSI Common Stock Exchange Value less the
per share exercise price multiplied by a factor in which the numerator is equal
to the number of exercisable stock options held by the holder and the
denominator is the CIBM Common Stock Exchange Value. CIBM shall pay cash in lieu
of fractional shares. As a condition to the receipt of such shares of CIBM
common stock and cash in lieu of fractional shares, each option holder shall
execute a cancellation agreement in form and substance reasonably satisfactory
to CIBM.

          (i)  Until surrendered, certificates representing Shares of CFSI
Common Stock will represent only the right to receive CIBM Common Stock and the
cash consideration hereunder, without interest, and no holder of any such
certificates shall have any further rights as a shareholder of CFSI.


                                   ARTICLE IV
              SURRENDER AND PAYMENT FOR SHARES OF CFSI COMMON STOCK

     4.1  Exchange of Shares. As soon as practicable after or prior to the
Effective Date, CIBM shall deposit or cause to be deposited with a bank or trust
company unaffiliated with CIBM (the "Exchange Agent"), for the benefit of
holders of CFSI Common Stock, certificates representing the shares of CIBM
Common Stock and cash in lieu of any fractional shares. Promptly after the
Effective Date, the Exchange Agent shall send to each shareholder of CFSI (other
than a shareholder who has asserted dissenters' rights under Sections 607.1302
and 607.1320) a notice and transmittal form advising such shareholder of the
terms of the exchange effected by the Merger and the procedure for surrendering
to the Exchange Agent each certificate evidencing CFSI Common Stock (a "CFSI
Certificate") in exchange for a certificate or certificates evidencing CIBM
Common Stock and cash in lieu of fractional shares, if any, to which such
shareholder is entitled under Section 3.1(b) of this Plan of Merger. The notice
and

                                                                          PAGE 6

transmittal form shall specify that delivery shall be effected, and risk of loss
of, and title to, each CFSI Certificate shall pass, only upon delivery of such
CFSI Certificate (or of a lost certificate affidavit in a form reasonably
acceptable to CIBM) to the Exchange Agent. Upon surrender of each CFSI
Certificate to the Exchange Agent for cancellation (or receipt by the Exchange
Agent of a lost certificate bond in a form reasonably acceptable to CIBM),
together with a duly executed copy of the transmittal form, the Exchange Agent
shall promptly distribute to the holder of each CFSI Certificate a certificate
or certificates evidencing the number of shares of CIBM Common Stock and cash in
lieu of fractional shares, if any, to which the holder of such CFSI Certificate
is entitled under Section 3.1(b) of this Plan of Merger, and each CFSI
Certificate so surrendered shall forthwith be canceled. All payments of cash
shall be made by check drawn to the order of the holder of record or other
person specified in the transmittal form in accordance with the requirements
thereof.

     4.2  CFSI Certificate Holder Rights. Until a CFSI Certificate is
surrendered and exchanged, each such outstanding CFSI Certificate shall for all
purposes evidence the right to receive the number of shares of CIBM Common Stock
and cash in lieu of fractional shares, if any, to which the holder of such CFSI
Certificate is entitled under Section 3.1(b) of this Plan of Merger. Whenever a
dividend or other distribution of property is declared by CIBM on CIBM common
stock after the Effective Date, the declaration shall include such dividends or
other distributions of property on all shares of CIBM common stock issuable
under this Plan of Merger but no former shareholder of CFSI will be entitled to
receive his or her dividend or other distribution of property until physical
exchange of his or her CFSI Certificates pursuant to Articles III and IV of this
Plan of Merger shall have been effected. Upon physical exchange of his or her
CFSI Certificate, any such person shall be entitled to receive from CIBM an
amount equal to all such dividends or distributions of property (without
interest thereon and less the amount of taxes, if any, which may have been
imposed or paid thereon) declared, and for which the payment has occurred, on
the shares of CIBM Common Stock issued in exchange for the shares of CFSI Common
Stock evidenced by such CFSI Certificate, subject to any applicable abandoned
property or similar laws.

     4.3  Closing CFSI Stock Transfer Book. As of the Effective Date, there
shall be no further registration or transfers on the stock transfer books of
CFSI of those shares of CFSI Common Stock which were outstanding immediately
prior to the Effective Date. If, after the Effective Date, CFSI Certificates
representing such shares are presented to CIBM or CIBMAC, such CFSI Certificates
shall be canceled and exchanged for certificates representing shares of CIBM
Common Stock and any cash in lieu of fractional shares, if any, as provided in
this Plan of Merger.

     4.4  CFSI Shareholder Payment Designations. If any certificates
representing shares of CIBM Common Stock are to be issued in the name of, or any
cash in lieu of fractional shares is to be paid to, a person other than the
holder of record of CFSI Certificate surrendered in exchange therefore, it shall
be a condition of the payment or issuance thereof that CFSI Certificate so
surrendered shall be properly endorsed, accompanied by any documents required to
evidence and effect such transfer and otherwise be in proper form for such
transfer, and that the person requesting such exchange shall pay to the Exchange
Agent any transfer or other taxes required by reason of such transfer or shall
establish to the satisfaction of the Exchange Agent that such tax has been paid
or is not applicable.

     RE:  Agreement and Plan of Reorganization, Dated March 6, 2001, among CIB
          Marine Bancshares, Inc. and Citrus Financial Services, Inc.


Ladies and Gentlemen:

     Reference is made to the Agreement and Plan of Reorganization (the
"Agreement") dated as of March 6, 2001, by and among CIB Marine Bancshares,
Inc., a Wisconsin corporation ("CIBM") and Citrus Financial Services, Inc., a
Florida corporation ("CFSI"), providing for the merger of CFSI with CIBM
Acquisition Corp., a wholly owned subsidiary corporation of CIBM organized or to
be organized under and by virtue of the laws of the State of Florida (the
"Merger"). Under the terms of the Agreement, all of the outstanding shares of
common stock of CFSI, $3.15 par value (the "CFSI Common Stock"), will be
converted into shares of common stock of CIBM, $1.00 par value (the "CIBM Common
Stock") and cash in lieu of fractional shares. The undersigned has been advised
that the issuance of shares of CIBM Common Stock to the undersigned in
connection with the Merger will be registered with the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the
"Securities Act"), on a Registration Statement on Form S-4 and that such
registration will not cover any resale or other disposition of CIBM Common
Stock.

     The undersigned also has been advised that the undersigned may be deemed to
be an affiliate of CIBM within the meaning of Rule 145 of the rules and
regulations of the SEC under the Securities Act and that the shares of CIBM
Common Stock acquired by the undersigned in connection with the Merger may only
be disposed of in conformity with the provisions hereof. The undersigned
represents and warrants to and agrees with CIBM and CFSI as follows:

          (a)  The undersigned shall not sell, exchange, transfer or otherwise
dispose of any shares of CIBM Common Stock received by the undersigned in the
Merger except (i) at such time as a registration statement under the Securities
Act covering sales of such CIBM Common Stock by the undersigned is effective,
(ii) within the limits, and in accordance with the applicable provisions of,
Rule 145 under the Securities Act, or (iii) in a transaction which, in the
opinion of counsel for the

                                                                          PAGE 2

undersigned or as described in a "no-action" or interpretive letter from the
staff of the ("SEC"), in each case satisfactory to CIBM, is not required to be
registered under the Securities Act. The undersigned acknowledges and agrees
that CIBM is under no obligation to register the sale, transfer or other
disposition of such CIBM Common Stock by the undersigned or on his or her
behalf, or to take any other action necessary to make an exemption from
registration available.

          (b)  Notwithstanding the foregoing, the undersigned shall not sell, or
in any other way reduce his or her risk relative to, any shares of (i) CFSI
Common Stock during the period commencing thirty (30) days prior to the
Effective Date of the Merger as defined in the Agreement, or (ii) CIBM Common
Stock received by the undersigned in the Merger during the period beginning with
the Effective Date of the Merger and ending on the date on which financial
results covering at least thirty days of post-Merger combined operations of CFSI
and CIBM have been published within the meaning of Section 201.01 of the SEC's
Codification of Financial Reporting Policies.

          (c)  CIBM shall not be bound by any attempted sale of any shares of
CIBM Common Stock by the undersigned, and CIBM's transfer agent shall be given
an appropriate stop transfer order and shall not be required to register any
such attempted sale, unless the sale has been effected in compliance with the
terms of this Letter Agreement.

          (d)  There will be placed on the certificate representing the shares
of CIBM Common Stock issued to the undersigned in the Merger, or any
substitutions therefore, a restrictive legend stating in substance:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
          PROVISIONS OF RULE 145(d), PROMULGATED UNDER THE SECURITIES ACT OF
          1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE
          DISPOSED OF WITHOUT COMPLIANCE WITH SAID RULE AND SECURITIES EXCHANGE
          COMMISSION ACCOUNTING RELEASES 130 AND 135."

          (e)  The provisions of paragraphs (a), (b), (c) and (d) hereof shall
also apply to any securities that may be paid as a dividend or otherwise
distributed on or with respect to, or issued or delivered in exchange or
substitution for, shares of CIBM Common Stock received in the Merger by the
undersigned.

          (f)  The undersigned does not have any present plan or intention to
sell or otherwise dispose of shares of CIBM Common Stock received by the
undersigned in the Merger.

          (g)  In the event the undersigned will be the owner of at least 5% of
the shares of CIBM immediately after the Merger, the undersigned undertakes to
give prompt written notice to CIBM, c/o Donald J. Straka, Senior Vice President
and General Counsel, if and as soon as, anytime after the date hereof and prior
to or on the Effective Date of the Merger, that the undersigned has a plan or
intention to sell or otherwise dispose of shares of CIBM Common Stock received

          (h)  The undersigned has the capacity to enter into this Letter
Agreement and to make the representations, warranties and agreements herein, and
to perform the obligations of the undersigned hereunder.

          (i)  This Letter Agreement constitutes a valid and binding obligation

shall be required to acknowledge in writing the terms of this Letter Agreement.

     CIBM agrees that the stop transfer instructions and legend referred to in
paragraphs (c) and (d) hereof will at the request of the undersigned, be
promptly removed upon (i) the sale, exchange, transfer or other disposition of
the CIBM Common Stock received in the Merger in full compliance with the
provisions of this Letter Agreement, or (ii) one year after the effective date
of the Merger, provided that, the undersigned is not an affiliate of CIBM and
adequate current public information with respect to CIBM is then available,
within the meaning of Rule144(c) under the Securities Act. CIBM agrees to
publish the financial results referred to in paragraph (b) above no later than
the date of filing of the first Quarterly Report on Form 10-Q or Annual Report
on Form 10-K that, in the ordinary course, would include financial results for
at least a thirty-day period following the effective date of the Merger. CIBM
further agrees that, promptly after publication of the financial results
referred to in paragraph (b) above, the portion of such legend referencing
Accounting Series Releases 130 and 135 shall be removed.

     This Letter Agreement shall terminate concurrently with any termination of
the Agreement in accordance with its terms.


Very truly yours,
