                       AGREEMENT AND PLAN OF MERGER

     This Agreement and Plan of Merger (the "PLAN OF MERGER") is made as of
February 24, 1999, between CFSB Bancorp, Inc., a Delaware corporation head-
quartered at 112 E. Allegan Street, Lansing, Michigan 48933 ("CFSB"), and
Old Kent Financial Corporation, a Michigan corporation headquartered at One
Vandenberg Center, 111 Lyon Street, N.W., Grand Rapids, Michigan 49503
("OLD KENT").

     Old Kent and CFSB desire that CFSB and its subsidiaries become affili-
ated with Old Kent.  The affiliation would be effected through the merger
of CFSB with and into Old Kent in accordance with this Plan of Merger and
in accordance with the Business Corporation Act of the State of Michigan,
as amended (the "MICHIGAN ACT") and the Delaware General Corporation Law,
as amended (the "DGCL").  The transactions contemplated by and described in
this Plan of Merger are referred to as the "MERGER."  Simultaneously with
or as soon as reasonably practical following the consummation of the
Merger, CFSB's wholly owned subsidiary, Community First Bank ("CFSB BANK"),
will be consolidated with and into Old Kent's wholly owned subsidiary, Old
Kent Bank.

     It is intended that, for federal tax purposes, the Merger qualify as a
reorganization under the provisions of Section 368 of the Internal Revenue
Code of 1986, as amended (the "INTERNAL REVENUE CODE").  It is also in-
tended that, for accounting and financial reporting purposes, the Merger
shall be accounted for as a pooling-of-interests.

     As a condition to, and concurrently with the execution of, this Plan
of Merger, CFSB and Old Kent are entering into a Stock Option Agreement
attached as EXHIBIT A (the "OPTION AGREEMENT").

     In consideration of the representations, warranties, and covenants
contained in this Plan of Merger, the parties agree:


                        ARTICLE I - THE TRANSACTION

     Subject to the terms and conditions of this Plan of Merger, the Merger
shall be carried out in the following manner:

     1.1  MERGER OF CFSB WITH AND INTO OLD KENT.  At the Effective Time,
CFSB shall be merged with and into Old Kent.  CFSB and Old Kent are each
sometimes referred to as a "CONSTITUENT CORPORATION" prior to the Merger.
At the Effective Time, the Constituent Corporations shall become a single
corporation, which shall be Old Kent (the "SURVIVING CORPORATION").  The
effect of the Merger upon each of the Constituent Corporations and the
Surviving Corporation shall be as provided in Chapter Seven of the Michigan
Act and Subchapter IX of the DGCL with respect to the merger of domestic




and foreign corporations, where the surviving corporation will be subject
to the laws of the State of Michigan.

     1.2  THE CLOSING.  The "CLOSING" shall be held at such time, date, and
location as may be mutually agreed by the parties.  In the absence of such
agreement, the Closing shall be held at the offices of Warner Norcross &
Judd LLP, 111 Lyon Street, N.W., Grand Rapids, Michigan, commencing at
11 a.m. on the earliest date specified by either party upon 10 business
days' written notice (or at the election of Old Kent, on the last business
day of the month) after the last to occur of the following events:  (a)
receipt of all consents and approvals of government regulatory authorities
legally required to consummate the Merger and the expiration of all statu-
tory waiting periods; and (b) adoption of this Plan of Merger by CFSB's
stockholders.  Scheduling or commencing the Closing shall not, however,
constitute a waiver of the conditions precedent of either Old Kent or CFSB
as set forth in Articles VI and VII, respectively.  Upon completion of the
Closing, CFSB and Old Kent shall each execute and file the certificates of
merger as required by the Michigan Act and DGCL to effect the Merger (col-
lectively, the "CERTIFICATES OF MERGER").

     1.3  EFFECTIVE TIME OF THE MERGER.  The Merger shall be consummated on
the next business day, or other mutually agreed upon date, following the
Closing by filing the Certificates of Merger in the manner required by law.
The "EFFECTIVE TIME" of the Merger shall be as of the time and date speci-
fied in the Certificates of Merger, but not later than the next business
day, or other mutually agreed upon date, following the Closing.

     1.4  BANK CONSOLIDATION.  After the Effective Time, Old Kent intends
to consolidate CFSB Bank and Old Kent Bank into a single Michigan banking
corporation where Old Kent Bank will be the consolidated bank resulting
from the transaction (the "BANK CONSOLIDATION").  The Bank Consolidation
will be effected pursuant to a consolidation agreement (the "BANK CONSOLI-
DATION AGREEMENT"), in the form required by the Michigan Banking Code of
1969, as amended (the "BANKING CODE"), and by other applicable laws, con-
taining terms and conditions, not inconsistent with this Plan of Merger, as
determined by Old Kent Bank.  The Bank Consolidation shall only occur if
the Merger is consummated, and it shall become effective immediately after
the Effective Time or such later time as may be determined by Old Kent.  To
obtain the necessary regulatory approval for the Bank Consolidation to
occur immediately after the Effective Time, CFSB and CFSB Bank shall each
execute and deliver the Bank Consolidation Agreement and take other reason-
ably required or convenient steps prior to the Effective Time to effect the
Bank Consolidation.  The effectiveness of the Bank Consolidation Agreement,
regardless of when executed and delivered, shall be subject to Old Kent's
action, in its capacity as the sole shareholder of CFSB Bank, to approve
the Bank Consolidation Agreement immediately after the Effective Time.



                                      -2-


     1.5  ADDITIONAL ACTIONS.  At any time after the Effective Time, the
Surviving Corporation may determine that further assignments or assurances
or any other acts are necessary or desirable to vest, perfect, or confirm,
of record or otherwise, in the Surviving Corporation its rights, title, or
interest in, to, or under any of the rights, properties, or assets of CFSB
acquired or to be acquired by the Surviving Corporation as a result of, or
in connection with, the Merger, or to otherwise carry out the purposes of
this Plan of Merger.  CFSB hereby grants to the Surviving Corporation an
irrevocable power of attorney to execute and deliver all such deeds, as-
signments, and assurances and to do all acts necessary, proper, or conve-
nient to accomplish this purpose.  This limited power of attorney shall
only be operative following the Effective Time.  The proper officers and
directors of the Surviving Corporation shall be fully authorized in the
name of CFSB to take any and all such action contemplated by this Plan of
Merger.

     1.6  SURVIVING CORPORATION.  Immediately after the Effective Time, the
Surviving Corporation shall have the following attributes until they are
subsequently changed in the manner provided by law:

               1.6.1  NAME.  The name of the Surviving Corporation shall be "Old
     Kent Financial Corporation."

               1.6.2  ARTICLES OF INCORPORATION.  The articles of incorporation
     of the Surviving Corporation shall be the articles of incorporation of
     Old Kent as in effect immediately prior to the Effective Time, without
     change.

               1.6.3  BYLAWS.  The bylaws of the Surviving Corporation shall be
     the bylaws of Old Kent as in effect immediately prior to the Effective
     Time, without change.

               1.6.4  DIRECTORS.  The directors of the Surviving Corporation
     shall be the same as the directors of Old Kent immediately prior to
     the Effective Time.

               1.6.5  OFFICERS.  The officers of the Surviving Corporation shall
     be the same as the officers of Old Kent immediately prior to the Ef-
     fective Time.


              ARTICLE II - CONVERSION AND EXCHANGE OF SHARES

     Subject to the terms and conditions of this Plan of Merger, the ex-
change of the common stock, $0.01 par value per share, of CFSB ("CFSB COM-
MON STOCK") for the common stock, $1 par value per share, of Old Kent ("OLD
KENT COMMON STOCK") shall be effected as follows:


                                      -3-


     2.1  CONVERSION OF SHARES.  At the Effective Time:

               2.1.1  CONVERSION OF CFSB COMMON STOCK.  Except as provided be-
     low, each share of CFSB Common Stock outstanding immediately prior to
     the Effective Time shall be converted automatically into 0.6222 (the
     "EXCHANGE RATIO") shares of validly issued, fully paid, and
     nonassessable Old Kent Common Stock.

               2.1.2  OLD KENT RIGHTS.  Each share of Old Kent Common Stock to
     be issued in the Merger will have attached to it the number of "Old
     Kent Rights" issuable pursuant to the "Old Kent Rights Agreement" (as
     those terms are defined in Section 3.4.1) then represented by each
     share of Old Kent Common Stock at the Effective Time, provided that
     the Old Kent Rights are not then separately transferable.

               2.1.3  NO CONVERSION OF OLD KENT COMMON STOCK.  Each share of Old
     Kent Common Stock outstanding immediately prior to the Effective Time
     shall continue to be outstanding without any change.  Each shareholder
     of Old Kent whose shares were outstanding immediately before the Ef-
     fective Time will hold the same number of shares of the Surviving
     Corporation, with identical designations, preferences, limitations,
     and relative rights, immediately after the Effective Time.

               2.1.4  STOCK HELD BY OLD KENT.  Each share of CFSB Common Stock,
     if any, held by Old Kent or any of its subsidiaries for its own ac-
     count, and not in a fiduciary capacity for a person other than Old
     Kent or any of its subsidiaries or as a result of debts previously
     contracted, shall be canceled and no consideration shall be issuable
     or payable with respect to any such share.

               2.1.5  TREASURY SHARES.  Each share of CFSB Common Stock held by
     CFSB as a treasury share, if any, shall be canceled and no Old Kent
     Common Stock or other consideration shall be issuable or payable with
     respect to any such share.

               2.1.6  CFSB COMMON STOCK NO LONGER OUTSTANDING.  Each share of
     CFSB Common Stock outstanding immediately prior to the Effective Time
     shall be considered to be no longer outstanding and to represent
     shares of Old Kent Common Stock as provided in this Plan of Merger,
     together with any dividends and other distributions payable as pro-
     vided in Section 2.5.4 (DIVIDENDS PENDING SURRENDER), but subject to
     the payment of cash in lieu of fractional shares as provided in Sec-
     tion 2.6 (NO FRACTIONAL SHARES).

     2.2  UPSET PROVISION.  After a Closing is properly called pursuant to
Section 1.2 (THE CLOSING), CFSB shall have the right to terminate this Plan
of Merger if the "Upset Condition" then exists.


                                      -4-


               2.2.1  The "UPSET CONDITION" shall exist if both of the following
     conditions then exist:

                      (a)  The Final Old Kent Price is less than $38.25 (the
          "FLOOR OLD KENT PRICE"); and

                      (b)  The number determined by dividing the Final Old Kent
          Price by $45.00 (the "INITIAL OLD KENT PRICE") is less than the
          number obtained by subtracting (i) 0.15 from (ii) the quotient
          obtained by dividing the Final Index Price (as defined below) by
          the Initial Index Price (as defined below).

               2.2.2  The "FINAL OLD KENT PRICE" means the average of the clos-
     ing prices per share of Old Kent Common Stock reported on the New York
     Stock Exchange ("NYSE") during the ten consecutive full trading days
     ending on the eleventh business day prior to the date of the Closing
     (the "PRICING PERIOD"), as reported in the DOW JONES NEWS/RETRIEVAL
     system, or other equally reliable means.

               2.2.3  The "INITIAL INDEX PRICE" means the Weighted Average (as
     defined below) of the closing prices per share of each of the common
     stocks of the Index Companies as reported on NYSE, The Nasdaq Stock
     Market ("NASDAQ"), or the American Stock Exchange ("AMEX") on February
     19, 1999.

               2.2.4  The "FINAL INDEX PRICE" means the Weighted Average of the
     average closing prices per share of each of the common stocks of the
     Index Companies as reported on NYSE, NASDAQ, or AMEX for the Pricing
     Period.

               2.2.5  "INDEX COMPANIES" means the companies listed on EXHIBIT B
     hereto.

               2.2.6  "WEIGHTED AVERAGE" means the average determined by giving
     the average closing prices for each of the Index Companies the corre-
     sponding weight listed on EXHIBIT B hereto.

               2.2.7  If Old Kent or any company listed on EXHIBIT B declares a
     stock dividend or effects a reclassification, recapitalization, split-
     up, combination, or subdivision of its common stock between February
     19, 1999 and the Effective Time, the closing prices for such common
     stock shall be appropriately adjusted for the purposes of the defini-
     tions above so as to be comparable to the price on February 19, 1999.
     There shall be excluded from the list of companies on EXHIBIT B any
     company as to which there is pending at any time during the Pricing
     Period any publicly announced proposal for such company to be acquired
     by another company in exchange for its stock or any other consider-
     ation.  In the event that any such company (or companies) is excluded

                                      -5-


     from the list of companies in EXHIBIT B, then the "Initial Index
     Price" and the "Final Index Price" shall be calculated as if the ex-
     cluded company had not originally been included in the list of compa-
     nies.

     2.3  ADJUSTMENTS.  The Exchange Ratio, Floor Old Kent Price, Initial
Old Kent Price, and Final Old Kent Price, and the related computations
described in Sections 2.1 (CONVERSION OF SHARES) and 2.2 (UPSET PROVISION)
shall be adjusted in the manner provided in this Section upon the occur-
rence of any of the following events:

               2.3.1  STOCK DIVIDENDS AND DISTRIBUTIONS.  If Old Kent declares a
     stock dividend, stock split, or other general distribution of Old Kent
     Common Stock to holders of Old Kent Common Stock prior to the date of
     the Effective Time, then:  (a)  the Floor Old Kent Price and the Ini-
     tial Old Kent Price, and if the ex-dividend or ex-distribution date
     for such stock dividend, stock split, or distribution occurs after the
     end of the Pricing Period, the Final Old Kent Price, shall each be
     adjusted by multiplying them by that ratio (i) the numerator of which
     shall be the total number of shares of Old Kent Common Stock outstand-
     ing immediately prior to such dividend, split, or distribution; and
     (ii) the denominator of which shall be the total number of shares of
     Old Kent Common Stock that are or will be outstanding immediately
     after such dividend, split, or distribution; and (b) the Exchange
     Ratio shall be adjusted by multiplying it by that ratio (i) the numer-
     ator of which shall be the total number of shares of Old Kent Common
     Stock that are or will be outstanding immediately after such dividend,
     split, or distribution; and (ii) the denominator of which shall be the
     total number of shares of Old Kent Common Stock outstanding immedi-
     ately prior to such dividend, split, or distribution.  For the pur-
     poses of this Section, the number of outstanding shares shall be com-
     puted as of the record date of the distribution.

               2.3.2  OTHER ACTION AFFECTING OLD KENT COMMON STOCK.  If there
     occurs, other than as described in the preceding subsection, any
     merger, business combination, recapitalization, reclassification,
     subdivision, or combination that would substantially change the number
     and value of outstanding shares of Old Kent Common Stock; a distribu-
     tion of warrants or rights with respect to Old Kent Common Stock; or
     any other transaction that would have a substantially similar effect;
     then the nature or amount of the consideration to be received by the
     stockholders of CFSB in exchange for their shares of CFSB Common Stock
     and the Exchange Ratio shall be adjusted in such manner and at such
     time as shall be equitable under the circumstances.  It is intended
     that in the event of a reclassification of outstanding shares of Old
     Kent Common Stock or a consolidation or merger of Old Kent with or
     into another corporation, other than a merger in which Old Kent is the


                                      -6-


     surviving corporation and which merger does not result in any reclas-
     sification of Old Kent Common Stock, holders of CFSB Common Stock
     would receive, in lieu of each share of Old Kent Common Stock to be
     issued in exchange for CFSB Common Stock based on the Exchange Ratio,
     the kind and amount of shares of Old Kent stock, other securities,
     money, and/or property receivable upon such reclassification, consoli-
     dation, or merger by holders of Old Kent Common Stock with respect to
     each share of Old Kent Common Stock outstanding immediately prior to
     such reclassification, consolidation, or merger.

               2.3.3  POSTPONEMENT OF CLOSING.  Old Kent and CFSB agree not to
     convene the Closing at any time that would result in there being a
     record date, ex-dividend date, or ex-distribution date for any trans-
     action described in Sections 2.3.1 (STOCK DIVIDENDS AND DISTRIBUTIONS)
     or 2.3.2 (OTHER ACTION AFFECTING OLD KENT COMMON STOCK) at any time
     during the Pricing Period.

               2.3.4  EMPLOYEE STOCK OPTIONS, ETC.  Notwithstanding any other
     provisions of this Section, no adjustment shall be made in the event
     of the issuance of additional shares of Old Kent Common Stock pursuant
     to Old Kent's Dividend Reinvestment Plan, pursuant to the exercise of
     stock options under stock option plans of Old Kent, or upon the grant
     or sale of shares or rights to receive shares to, or for the account
     of, Old Kent directors or employees pursuant to restricted stock,
     deferred stock compensation, thrift, employee stock purchase, and
     other benefit plans of Old Kent.

               2.3.5  AUTHORIZED BUT UNISSUED SHARES.  Notwithstanding the other
     provisions of this Section, no adjustment shall be made in the event
     of the issuance of additional shares of Old Kent Common Stock or other
     securities pursuant to a public offering, private placement, or an
     acquisition of one or more banks, corporations, or business assets for
     consideration that the board of directors of Old Kent, or a duly au-
     thorized committee thereof, determines to be fair and reasonable.

               2.3.6  CHANGES IN CAPITAL.  Subject only to making any adjustment
     to the Exchange Ratio and related computations prescribed by this
     Section, nothing contained in this Plan of Merger is intended to pre-
     clude Old Kent from amending its Restated Articles of Incorporation to
     change its capital structure or from issuing additional shares of Old
     Kent Common Stock, preferred stock, shares of other capital stock, or
     securities that are convertible into shares of capital stock.

               2.3.7  INCREASE IN OUTSTANDING SHARES OF CFSB COMMON STOCK.  In
     the event that the number of shares of CFSB Common Stock outstanding
     is greater than 8,230,937 for any reason whatsoever (whether or not
     such increase constitutes a breach of this Plan of Merger), other than


                                      -7-


     the issuance of not more than 407,922 shares upon the exercise of CFSB
     stock options identified in Section 4.4 (CAPITAL STOCK), then the
     Exchange Ratio shall be adjusted by multiplying it by a fraction
     (i) the numerator of which shall be 8,230,937 (the total number of
     shares of CFSB Common Stock outstanding as of the date of this Plan of
     Merger); and (ii) the denominator of which shall be the total number
     of shares of CFSB Common Stock outstanding as of the Effective Time of
     the Merger, excluding not more than 407,922 shares, if any, issued
     after the date of this Plan of Merger upon the exercise of CFSB stock
     options identified in Section 4.4 (CAPITAL STOCK).

     2.4  CESSATION OF STOCKHOLDER STATUS.  As of the Effective Time, each
record holder of shares of CFSB Common Stock outstanding immediately prior
to the Effective Time shall cease to be a stockholder of CFSB and shall
have no rights as a CFSB stockholder.  Each stock certificate representing
shares of CFSB Common Stock ("OLD CERTIFICATES") shall then be considered
to represent shares of Old Kent Common Stock and the right to receive cash
in lieu of fractional shares, all as provided in this Plan of Merger.

     2.5  SURRENDER OF OLD CERTIFICATES AND DISTRIBUTION OF OLD KENT COMMON
STOCK.  After the Effective Time, Old Certificates shall be exchangeable by
the holders thereof for new stock certificates representing the number of
shares of Old Kent Common Stock to which such holders shall be entitled in
the following manner:

               2.5.1  TRANSMITTAL MATERIALS.  As soon as practicable after the
     Effective Time, Old Kent shall send or cause to be sent to each record
     holder of CFSB Common Stock as of the Effective Time transmittal mate-
     rials for use in exchanging that holder's Old Certificates for Old
     Kent Common Stock certificates.  The transmittal materials will con-
     tain instructions with respect to the surrender of Old Certificates.

               2.5.2  EXCHANGE AGENT.  On or prior to the Effective Time, Old
     Kent will deliver to Old Kent Bank, a Michigan banking corporation, or
     such other bank or trust company as Old Kent may designate (the "EX
     CHANGE AGENT"), certificates representing the number of shares of Old
     Kent Common Stock issuable and the amount of cash payable for frac-
     tional shares in the Merger.  The Exchange Agent shall not be entitled
     to vote or exercise any rights of ownership with respect to such
     shares of Old Kent Common Stock, except that it shall receive and hold
     all dividends or other distributions paid or distributed with respect
     to such shares for the account of the persons entitled to such shares.

               2.5.3  DELIVERY OF NEW CERTIFICATES.  Old Kent shall cause the
     Exchange Agent to promptly issue and deliver stock certificates in the
     names and to the addresses that appear on CFSB's stock records as of
     the Effective Time, or in such other name or to such other address as


                                      -8-


     may be specified by the holder of record in transmittal documents
     received by the Exchange Agent; provided, that with respect to each
     CFSB stockholder, the Exchange Agent shall have received all of the
     Old Certificates held by that stockholder, or an affidavit of loss and
     indemnity bond for such certificate or certificates, together with
     properly executed transmittal materials; and such certificates, trans-
     mittal materials, affidavits, and bonds are in a form and condition
     reasonably acceptable to Old Kent and the Exchange Agent.

               2.5.4  DIVIDENDS PENDING SURRENDER.  Whenever a dividend is de-
     clared by Old Kent on Old Kent Common Stock that is payable to share-
     holders of record of Old Kent as of a record date on or after the date
     of the Effective Time, the declaration shall include dividends on all
     shares issuable under this Plan of Merger.  No former stockholder of
     CFSB shall be entitled to receive a distribution of any such dividend
     until the physical exchange of that stockholder's Old Certificates for
     new Old Kent Common Stock certificates shall have been effected.  Upon
     the physical exchange of that stockholder's Old Certificates, that
     stockholder shall be entitled to receive from Old Kent an amount equal
     to all such dividends (without interest thereon and less the amount of
     taxes, if any, that may have been imposed or paid thereon) declared
     and paid with respect to the shares of Old Kent Common Stock repre-
     sented thereby.

               2.5.5  STOCK TRANSFERS.  On or after the Effective Time, there
     shall be no transfers on CFSB's stock transfer books of the shares of
     CFSB Common Stock that were issued and outstanding immediately prior
     to the Effective Time.  If, after the Effective Time, Old Certificates
     are properly presented for transfer, then they shall be canceled and
     exchanged for stock certificates representing shares of Old Kent Com-
     mon Stock as provided in this Plan of Merger.  After the Effective
     Time, ownership of such shares as are represented by any Old Certifi-
     cates may be transferred only on the stock transfer records of Old
     Kent.

               2.5.6  EXCHANGE AGENT'S DISCRETION.  The Exchange Agent shall
     have discretion to determine reasonable rules and procedures relating
     to the exchange (or lack thereof) of Old Certificates and the issuance
     and delivery of new certificates of Old Kent Common Stock into which
     shares of CFSB Common Stock are converted in the Merger and governing
     the payment for fractional shares of CFSB Common Stock.

     2.6  NO FRACTIONAL SHARES.  Notwithstanding any other provision of
this Article II, no certificates or scrip representing fractional shares of
Old Kent Common Stock shall be issued in the Merger (taking into account
all shares held by a particular CFSB stockholder) upon the surrender of Old
Certificates.  No fractional interest in any share of Old Kent Common Stock
resulting from the Merger shall be entitled to any part of a dividend,

                                      -9-


distribution, or stock split with respect to shares of Old Kent Common
Stock nor entitle the record holder to vote or exercise any rights of a
shareholder with respect to that fractional interest.  In lieu of issuing
any fractional share, each holder of an Old Certificate who would otherwise
have been entitled to a fractional share of Old Kent Common Stock upon
surrender of all Old Certificates for exchange shall be paid an amount in
cash (without interest) equal to such fraction of a share multiplied by the
Final Old Kent Price.

     2.7  ASSUMPTION OF STOCK OPTIONS.  Before the Effective Time of the
Merger, CFSB shall amend, if necessary, the terms of all outstanding stock
options granted by CFSB ("UNEXERCISED OPTIONS") pursuant to CFSB's 1990
Stock Option Plan and 1994 Stock Option and Incentive Plan (collectively,
the "OPTION PLANS") so that they shall, if and when the Merger becomes
effective, cease to represent the right to acquire shares of CFSB Common
Stock and each such option shall become by assumption at the Effective Time
an option to acquire that number of shares of Old Kent Common Stock equal
to (a) the number of shares of CFSB Common Stock subject to the Unexercised
Option, multiplied by (b) the Exchange Ratio, rounded to the nearest whole
share. The exercise price per share of Old Kent Common Stock under the
assumed option shall be equal to the exercise price per share of the CFSB
Common Stock that was purchasable under each Unexercised Option divided by
the Exchange Ratio (rounded to the nearest whole cent).  In addition, each
option that is an "incentive stock option" as defined in Section 422 of the
Internal Revenue Code shall be adjusted as required by Section 424 of the
Internal Revenue Code and the regulations issued thereunder so as not to
constitute a modification, extension or renewal of the option within the
meaning of section 424 of the Internal Revenue Code.  The duration and
other terms and conditions of the assumed options shall be the same as the
original CFSB options, except that any reference to CFSB shall be consid-
ered to be references to Old Kent.  At all times after the Effective Time
until all such options have been exercised or terminated, Old Kent shall
reserve for issuance such number of shares of Old Kent Common Stock as
necessary so as to permit the exercise of such options.  Old Kent shall use
its best efforts to file as soon as possible after the Effective Time, and
in no event later than 15 days after the Effective Time, and use its best
efforts to maintain the effectiveness of, a registration statement with the
Securities and Exchange Commission (the "SEC"), covering such options and
the sale of the Old Kent Common Stock issuable upon exercise of such op-
tions so long as unexercised options remain outstanding.  At the Effective
Time, the Option Plans shall be terminated with respect to the granting of
any additional options or option rights.  Old Kent acknowledges and agrees
that the Merger would constitute a "change in control" pursuant to the
Option Plans resulting in acceleration of the vesting of any options that
have not yet vested.  In no event and at no time shall CFSB (including its
board of directors or any committee thereof) permit or allow the holder of
any Unexercised Option to receive cash in exchange for the cancellation of
such Unexercised Option.

                                      -10-

     3.6  FINANCIAL STATEMENTS.

          3.6.1  FINANCIAL STATEMENTS.  The consolidated financial state-
ments of Old Kent and its subsidiaries as of and for the each of three
years ended December 31, 1995, 1996, and 1997, as reported on by Old Kent's
independent accountants, and the unaudited, draft consolidated financial
statements of Old Kent and its subsidiaries as of and for the year ended
December 31, 1998, including all schedules and notes relating to such
statements (collectively, "OLD KENT'S FINANCIAL STATEMENTS"), fairly pres-
ent the financial condition and the results of operations, changes in
shareholders' equity, and cash flows of Old Kent as of the respective dates
of and for the periods referred to in such financial statements, all in
accordance with generally accepted United States accounting principles
("GAAP") consistently applied except as stated therein.  The unaudited
consolidated financial statements of Old Kent and its subsidiaries as of
and for each of the three quarters ended September 30, 1998, and each quar-
ter thereafter until the Effective Time, including all schedules and notes
relating to such statements, are correct and complete, and as to future
quarters will be correct and complete, in all material respects.

               3.6.2  CALL REPORTS.  The following reports (including all re-
     lated schedules, notes, and exhibits) were prepared and filed in con-
     formity with applicable regulatory requirements and were correct and
     complete in all material respects when filed:

                  (a)  The consolidated reports of condition and income of Old
          Kent Bank as of and for each of the years ended December 31,
          1995, 1996, and 1997, as filed with the FDIC; and

                  (b)  The FR Y-9 and FR Y-6 for Old Kent and Old Kent Bank as
          of and for each of the years ended December 31, 1995, 1996, and
          1997, as filed with the Federal Reserve Board.

          All of such reports required to be filed prior to the Closing by Old
     Kent and/or Old Kent Bank will be prepared and filed in conformity
     with applicable regulatory requirements applied consistently through
     out their respective periods (except as otherwise noted in such re-
     ports) and will be correct and complete in all material respects when
     filed.

     3.7  ABSENCE OF UNDISCLOSED LIABILITIES.  Except as and to the extent
reflected or reserved against in Old Kent's Financial Statements as of


                                      -14-


December 31, 1998, as of such date, neither Old Kent nor any of its subsid-
iaries had liabilities or obligations, secured or unsecured (whether ac-
crued, absolute, or contingent) as to which there is a reasonable probabil-
ity that they could have a Material Adverse Effect on Old Kent.

     3.8  ABSENCE OF MATERIAL ADVERSE CHANGE.  Since December 31, 1998,
there has been no change in the financial condition, income, expenses, or
business of Old Kent and its subsidiaries (and not the banking industry as
a whole) that had, or is reasonably likely in the future to have, a Mate-
rial Adverse Effect on Old Kent.  No facts or circumstances, that are not
applicable to the banking industry as a whole, have been discovered from
which it reasonably appears that there is a reasonable probability that
there will occur a change in Old Kent's financial condition, income, ex-
penses, assets, liabilities, or business that would have a Material Adverse
Effect on Old Kent.

     3.9  ABSENCE OF LITIGATION.  Except as disclosed in Old Kent's filings
with the SEC, there is no action, suit, proceeding, claim, arbitration, or
investigation pending or, to Old Kent's knowledge, threatened by any per-
son, including without limitation any governmental or regulatory agency,
against Old Kent or any of its subsidiaries, or the assets or business of
Old Kent or any of its subsidiaries, any of which has had or in the future
would have a Material Adverse Effect on Old Kent.  There is no factual
basis known to Old Kent that presents a reasonable potential for any such
action, suit, proceeding, claim, arbitration, or investigation.

     3.10  REGULATORY FILINGS.  In the last two years:

               3.10.1  SEC FILINGS.  Old Kent has filed, and will in the future
     continue to file, in a timely manner all required filings with the
     SEC, including without limitation all reports on Form 10-K and
     Form 10-Q;

               3.10.2  REGULATORY FILINGS.  Old Kent has filed in a timely man-
     ner all other material filings with other regulatory bodies for which
     filings are required; and

               3.10.3  COMPLETE AND ACCURATE.  All such filings, as of their
     respective filing dates, did not contain any untrue statement of mate-
     rial 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.

     3.11  REGISTRATION STATEMENT, ETC.

               3.11.1  "TRANSACTION DOCUMENTS."  The term "TRANSACTION DOCU-
     MENTS" shall collectively mean: (i) the registration statement to be


                                      -15-


     filed by Old Kent with the SEC (the "REGISTRATION STATEMENT") in con-
     nection with the Old Kent Common Stock to be issued in the Merger;
     (ii) the prospectus and proxy statement (the "PROSPECTUS AND PROXY
     STATEMENT") to be mailed to CFSB stockholders in connection with the
     Stockholders' Meeting (as defined below); and (iii) any other docu-
     ments to be filed with the SEC, the Federal Reserve Board, the Office
     of Thrift Supervision ("OTS"), the Financial Institutions Bureau
     ("FIB"), the states of Michigan or Delaware, or any other regulatory
     agency in connection with the transactions contemplated by this Plan
     of Merger.

               3.11.2  ACCURATE INFORMATION.  The information to be supplied by
     Old Kent for inclusion or incorporation by reference in any Transac-
     tion Document will not contain any untrue statement of 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 circum-
     stances under which they were made, not misleading (a) at the respec-
     tive times such Transaction Documents are filed; (b) with respect to
     the Registration Statement, when it becomes effective; and (c) with
     respect to the Prospectus and Proxy Statement, when it is mailed and
     at the time of the Stockholders' Meeting.

               3.11.3  COMPLIANCE OF FILINGS.  All documents that Old Kent is
     responsible for filing with the SEC or any regulatory agency in con-
     nection with the Merger will comply as to form in all material re-
     spects with the provisions of applicable law and regulation.

     3.12  INVESTMENT BANKERS AND BROKERS.  Old Kent has not employed any
broker, finder, or investment banker in connection with the Merger.  Old
Kent has no express or implied agreement with any other person or company
relative to any commission or finder's fee payable with respect to this
Plan of Merger or the transactions contemplated by it.

     3.13  ACCOUNTING AND TAX TREATMENT.   Neither Old Kent nor, to its
knowledge, any of its affiliates, has taken or agreed to take any action or
knows of any reason that, with respect to Old Kent and its affiliates,
would prevent Old Kent from accounting for the business combination to be
effected by the Merger as a pooling-of-interests.  Old Kent is aware of no
reason why the Merger will fail to qualify as a reorganization under Sec-
tion 368(a) of the Internal Revenue Code.

     3.14  AGREEMENTS WITH BANK REGULATORS.  Neither Old Kent nor any of
Old Kent's subsidiaries is a party to any agreement or memorandum of under
standing with, or a party to any commitment letter, board resolution or
similar undertaking to, or is subject to any order or directive by, or is a
recipient of any extraordinary supervisory letter from, any governmental
authority that restricts materially the conduct of its business, or in any
manner relates to its capital adequacy, its credit or reserve policies or

                                      -16-


its management, nor has Old Kent been advised by any governmental authority
that it is contemplating issuing or requesting (or is considering the ap-
propriateness of issuing or requesting) any such order, decree, agreement,
memorandum of understanding, extraordinary supervisory letter, commitment
letter or similar submission.  Neither Old Kent nor any of Old Kent's sub-
sidiaries is required by applicable law to give prior notice to a Federal
banking agency of the proposed addition of an individual to its board of
directors or the employment of an individual as a senior or executive offi-
cer.  As of the date of this Plan of Merger, Old Kent knows of no reason
why the regulatory approvals referred to in Sections 3.1.4 and 4.1.4 (RE-
QUIRED APPROVALS) should not be obtained.

     3.15  EVENTS SINCE DECEMBER 31, 1998.  Neither Old Kent nor any of Old
Kent's subsidiaries has, since December 31, 1998, conducted its business
other than in the ordinary course or as contemplated by this Plan of
Merger.

     3.16  RESERVE FOR LOAN LOSSES.  The reserve for credit losses as re-
flected in Old Kent's Financial Statements were (a) adequate to meet all
reasonably anticipated credit losses, net of recoveries related to assets
previously charged off as of those dates, and (b) consistent with GAAP and
safe and sound banking practices.

     3.17  PUBLIC COMMUNICATIONS; SECURITIES OFFERING.  Each annual report,
quarterly report, proxy material, press release, or other communication
previously sent or released by Old Kent to Old Kent's shareholders or the
public did not contain any untrue statement of 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 that they were
made, not misleading.

     3.18  YEAR 2000 COMPLIANCE.  Old Kent has:  (i) initiated a review and
assessment of all areas within the business and operations (including those
affected by material suppliers and vendors) of Old Kent and each of its
subsidiaries that could be adversely affected by the "YEAR 2000 PROBLEM,"
meaning the risk that computer applications used by Old Kent or any of its
subsidiaries (or material suppliers and vendors) may be unable to recognize
and perform properly date-sensitive functions involving certain dates prior
to and any date after December 31, 1999; (ii) developed a plan and time
line for addressing the Year 2000 Problem on a timely basis; and (iii) to
date, implemented that plan in accordance with that timetable.  Old Kent
believes that all computer applications (including those of its material
suppliers and vendors) that are material to the business and operations of
Old Kent or any of its subsidiaries will on a timely basis be able to per-
form properly date-sensitive functions for all dates before and after Janu-
ary 1, 2000, except to the extent that a failure to do so would not have a
Material Adverse Effect on Old Kent.


                                      -17-


     3.19  TRUE AND COMPLETE INFORMATION.  No schedule, statement, list,
certificate, or other information furnished or to be furnished by Old Kent
in connection with this Plan of Merger, including the Old Kent Disclosure
Statement, contains or will contain any untrue statement of a material
fact, or omits or will omit to state a material fact necessary to make the
statements contained therein, in light of the circumstances in which they
are made, not misleading.

     qualified or admitted to conduct business in each state where such
     qualification or admission is required except that state or those

     (a) 15,000,000 shares of common stock, $0.01 par value per share, of
     which 8,230,937 shares are issued and outstanding as of February 19,

     and, except for Unexercised Options to acquire up to 407,922 shares of
     CFSB Common Stock under the Option Plans, there are no outstanding
     subscriptions, options, warrants, or rights to acquire any capital
     stock of CFSB, or agreements to which CFSB is a party or by which it
     is bound to issue capital stock.  No stock option agreement issued
     under an Option Plan requires the payout of cash in exchange for the
     cancellation of such Unexercised Option.

     tants, and the unaudited, draft consolidated financial statements of
     CFSB as of and for the year ended December 31, 1998, including all
     schedules and notes relating to such statements, as previously deliv-
     ered to Old Kent (collectively, "CFSB'S FINANCIAL STATEMENTS"), fairly
     present the financial condition and the results of operations, changes
     in stockholders' equity, and cash flows of CFSB as of the respective
     dates of and for the periods referred to in such financial statements,
     all in accordance with GAAP, consistently applied except as stated

               4.5.2  CALL REPORTS.  The following reports (including all re-
     lated schedules, notes, and exhibits) were prepared and filed in con-
     formity with applicable regulatory requirements and were correct and
     complete in all material respects when filed:

                   (a)  The consolidated reports of condition and income of
          CFSB Bank as of and for each of the years ended December 31,
          1995, 1996, and 1997, as filed with the FDIC and the OTS, as
          applicable; and

                   (b)  The Form H - (b)11 report for CFSB  as of and for each
          of the years ended December 31, 1995, 1996, and 1997, as filed
          with the OTS.

          All of such reports required to be filed prior to the Closing by CFSB
     and/or CFSB Bank will be prepared and filed in conformity with appli-
     cable regulatory requirements applied consistently throughout their
     respective periods (except as otherwise noted in such reports) and
     will be correct and complete in all material respects when filed.  All
     of the reports identified in this Section are collectively referred to
     as the "CALL REPORTS."

     4.6  ABSENCE OF UNDISCLOSED LIABILITIES.  Except as and to the extent
reflected or reserved against in CFSB's Financial Statements as of
December 31, 1998, neither CFSB nor any of CFSB's subsidiaries had, as of
such date, liabilities or obligations, secured or unsecured (whether ac-
crued, absolute, or contingent) as to which there is a reasonable probabil-
ity that they could have a Material Adverse Effect on CFSB.

     4.7  ABSENCE OF MATERIAL ADVERSE CHANGE.  Since December 31, 1998,
there has been no change in the financial condition, income, expenses,
assets, liabilities or business of CFSB (and not the banking industry as a
whole) that had, or is reasonably likely in the future to have, a Material
Adverse Effect.  No facts or circumstances, that are not applicable to the
banking industry as a whole, have been discovered from which it reasonably
appears that there is a reasonable probability that there will occur a
change in CFSB's financial condition, income, expenses, assets, liabilities
or business that would have a Material Adverse Effect on CFSB.

     4.8  ABSENCE OF LITIGATION.  There is no action, suit, proceeding,
claim, arbitration, or investigation pending or, to the knowledge of CFSB,
threatened by any person, including without limitation any governmental or
regulatory agency, against CFSB or any of CFSB's subsidiaries, or the as
sets or business of CFSB or any of CFSB's subsidiaries, any of which has
had or in the future could have a Material Adverse Effect on CFSB.  There
is no factual basis known to CFSB that presents a reasonable potential for
any such action, suit, proceeding, claim, arbitration, or investigation.


                                      -22-


     4.9  CONDUCT OF BUSINESS.  CFSB and each of CFSB's subsidiaries have
conducted their respective businesses and used their respective properties
in substantial compliance with all federal, state, and local laws, civil or
common, ordinances and regulations, including without limitation applicable
federal and state laws and regulations concerning banking, securities,
truth-in-lending, truth-in-savings, mortgage origination and servicing,
usury, fair credit reporting, consumer protection, occupational safety,
civil rights, employee protection, fair employment practices, fair labor
standards, and insurance; and Environmental Laws (as defined in
Section 4.22.2 (ENVIRONMENTAL LAWS)); except for violations (individually
or in the aggregate) that would not have a Material Adverse Effect on CFSB.

     4.10  CONTRACTS.  There is no existing default by CFSB or any of
CFSB's subsidiaries, or any other party, under any contract or agreement to
which CFSB or any of CFSB's subsidiaries is a party, or by which they are
bound, the result of which would have a Material Adverse Effect on CFSB.
Excepting any ordinary and customary banking relationships, there are no
material agreements, contracts, mortgages, deeds of trust, leases, commit-
ments, indentures, notes, or other instruments under which another party is
in material default under its obligations to CFSB or its subsidiaries.
CFSB is not party to any contract, agreement, arrangement, or understanding
(other than ordinary and customary banking relationships) that would re-
quire CFSB or any of its subsidiaries to make payments or make expenditures
in excess of $100,000 per year or that would require any payment to another
party upon termination in excess of $25,000.

     4.11  REGULATORY FILINGS.  In the last five years:

               4.11.1   SEC FILINGS.  CFSB has filed, and in the future will
     continue to file, in a timely manner all required filings with the
     SEC, including without limitation all reports on Form 10-K and Form
     10-Q;

               4.11.2  REGULATORY FILINGS.  CFSB has filed in a timely manner
     all other filings with other regulatory bodies for which filings are
     required; and

                4.11.3  COMPLETE AND ACCURATE.  All such filings, as of their
     respective filing dates, did not contain any untrue statement of mate-
     rial 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.  All such
     filings complied in all material respects with all laws, regulations,
     forms, and guidelines applicable to such filings.





                                      -23-


     4.12  REGISTRATION STATEMENT, ETC.

               4.12.1  ACCURATE INFORMATION.  The information to be supplied by
     CFSB for inclusion or incorporation by reference in any Transaction
     Document will not contain any untrue statement of material fact or
     omit to state a material fact required to be stated therein or neces-
     sary to make the statements therein, in light of the circumstances
     under which they were made, not misleading (a) at the respective times
     such Transaction Documents are filed; (b) with respect to the Regis-
     tration Statement, when it becomes effective; and (c) with respect to
     the Prospectus and Proxy Statement, when it is mailed and at the time
     of the Stockholders' Meeting.

               4.12.2  COMPLIANCE OF FILINGS.  All documents that CFSB is re-
     sponsible for filing with the SEC or any regulatory agency in connec-
     tion with the Merger will comply as to form in all material respects
     with the provisions of applicable law and regulation.

     4.13  AGREEMENTS WITH BANK REGULATORS.  Neither CFSB nor any of CFSB's
subsidiaries is a party to any agreement or memorandum of understanding
with, or a party to any commitment letter, board resolution or similar
undertaking to, or is subject to any order or directive by, or is a recipi-
ent of any extraordinary supervisory letter from, any governmental author-
ity that restricts materially the conduct of its business, or in any manner
relates to its capital adequacy, its credit or reserve policies or its
management, nor has CFSB been advised by any governmental authority that it
is contemplating issuing or requesting (or is considering the appropriate-
ness of issuing or requesting) any such order, decree, agreement, memoran-
dum of understanding, extraordinary supervisory letter, commitment letter
or similar submission.  Neither CFSB nor any of CFSB's subsidiaries is
required by applicable law to give prior notice to a Federal banking agency
of the proposed addition of an individual to its board of directors or the
employment of an individual as a senior or executive officer.  As of the
date of this Plan of Merger, CFSB knows of no reason why the regulatory
approvals referred to in Sections 3.1.4 and 4.1.4 (REQUIRED APPROVALS)
should not be obtained.

     4.14  TAX MATTERS.

               4.14.1  TAX RETURNS.  CFSB and each of CFSB's subsidiaries have
     duly and timely filed all tax returns that they have by law been re-
     quired to file, including without limitation those with respect to
     income, withholding, social security, unemployment, franchise, real
     property, personal property, sales, use, and intangibles taxes.  Each
     such tax return, report, and statement, as amended, is correct and
     complies in all material respects with all applicable laws and regula-
     tions.


                                      -24-


               4.14.2  TAX ASSESSMENTS AND PAYMENTS.  All taxes and assessments,
     including any penalties, interest, and deficiencies relating to those
     taxes and assessments, due and payable by CFSB and CFSB's subsidiaries
     have been paid in full as and when due, including applicable extension
     periods.  The provisions made for taxes on CFSB's Financial Statements
     as of December 31, 1998, are sufficient for the payment of all fed-
     eral, state, county, and local taxes of CFSB accrued but unpaid as of
     the date indicated, whether or not disputed, with respect to all peri-
     ods through December 31, 1998.

               4.14.3  TAX AUDITS.  None of the federal, state, or local consol-
     idated franchise or income tax returns of CFSB and its subsidiaries
     filed for any tax year after 1989 have been audited by the Internal
     Revenue Service (the "IRS").  There is no tax audit or legal or admin-
     istrative proceeding for assessment or collection of taxes pending or,
     to CFSB's knowledge, threatened with respect to CFSB or any of CFSB's
     subsidiaries.  No claim for assessment or collection of taxes has been
     asserted with respect to CFSB or any of CFSB's subsidiaries that has
     not been finally resolved and paid or accrued for.  No waiver of any
     limitations statute or extension of any assessment or collection pe-
     riod has been executed by or on behalf of CFSB or any of CFSB's sub-
     sidiaries.

     4.15  TITLE TO PROPERTIES.  CFSB and each of its subsidiaries have
good and marketable title to all of their properties and assets, whether
real, personal, or a combination thereof, reflected in their books and
records as being owned (including those reflected in CFSB's Financial
Statements as of December 31, 1998, except as since disposed of in the
ordinary course of business), free and clear of all liens and encumbrances,
except:

               4.15.1  REFLECTED ON BALANCE SHEET.  As reflected on CFSB's Fi-
     nancial Statements as of December 31, 1998;

               4.15.2  NORMAL TO BUSINESS.  Liens for current taxes not yet
     delinquent, and liens or encumbrances that are normal to the business
     of CFSB and that would not have a Material Adverse Effect on CFSB; and

               4.15.3  IMMATERIAL IMPERFECTIONS.  Such imperfections of title,
     easements, restrictions, and encumbrances, if any, as are not material
     in character, amount, or extent, and do not materially detract from
     the value, or materially interfere with the present use, of the prop-
     erties subject thereto or affected thereby.

     4.16  CONDITION OF REAL PROPERTY.  With respect to each parcel of real
property owned, legally and beneficially, by CFSB or CFSB's subsidiaries,
including other real estate owned ("CFSB'S REAL PROPERTY"), to its knowl-
edge:

                                      -25-


               4.16.1  NO ENCROACHMENTS.  No building or improvement to CFSB's
     Real Property encroaches on any easement or property owned by another
     person.  No building or property owned by another person encroaches on
     CFSB's Real Property or on any easement benefitting CFSB's Real Prop-
     erty.  None of the boundaries of CFSB's Real Property deviates sub-

     rights from all appropriate federal, state, and other public authori-

     sidiaries has within the last five years been charged by a regulatory

          the Premises is constructed of, or contains as a component part,
          any material that (either in its present form or as it may rea-
          sonably be expected to change through aging or normal use) re-
          leases or may release any Hazardous Substance in violation of
          applicable law.  Without limiting the generality of this Section,
          to the knowledge of CFSB, the Premises are free of asbestos ex-
          cept to the extent properly sealed or encapsulated in compliance
          with all applicable Environmental Laws and all workplace safety
          and health laws and regulations.

                    (b)  USES OF PREMISES.  To its knowledge, no part of the

          mises do not contain, and have never contained, any underground
          storage tanks.  With respect to any underground storage tank that

          foregoing, each such underground storage tank presently or previ-
          ously located on Premises is or has been maintained or removed,
          as applicable, in compliance with all applicable Environmental
          Laws, and has not been the source of any release of a Hazardous
          Substance to the environment that has not been remediated.

                    (d)  ABSENCE OF CONTAMINATION.  To its knowledge, the Pre-
          mises do not contain and are not contaminated by any reportable

          ble cleanup standards, of a Hazardous Substance from any source.

                    (e)  ENVIRONMENTAL SUITS AND PROCEEDINGS.  To its knowledge
          after reasonable inquiry, there is no action, suit, investiga-
          tion, liability, inquiry, or other proceeding, ruling, order,

          asserted under, or as a result of any actual or alleged failure
          to comply with any requirement of, any Environmental Law.  To its

                                      -31-

did not contain any untrue statement of material fact or omit to state a
material fact required to be stated therein or necessary to make the state-
ments therein, in light of the circumstances under that they were made, not
misleading.

     4.34  NO INSIDER TRADING.  CFSB has reviewed its stock transfer re-
cords since December 31, 1995, and has questioned its directors and execu-
tive officers concerning known stock transfers since that date.  Based upon
that investigation, CFSB has not, and to CFSB's knowledge (a) no director
or officer of CFSB, (b) no person related to any such director or officer
by blood or marriage and residing in the same household, and (c) no person
knowingly provided material nonpublic information by any one or more of
these persons; has purchased or sold, or caused to be purchased or sold,
any shares of CFSB Common Stock during any period when CFSB was in posses-
sion of material nonpublic information or in violation of any applicable
provision of the Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT").

     4.35  DATA PROCESSING CONTRACTS.  All material data processing con-
tracts of CFSB or CFSB's subsidiaries are cancelable on or before September
30, 1999, without cost or penalty.

     4.36  YEAR 2000 COMPLIANCE.  CFSB and CFSB Bank have adopted plans and
procedures consistent with good business practices and the requirements of
their primary thrift regulator for their Year 2000 Assets (as defined be-
low) to be timely modified, upgraded or replaced to become Year 2000 Ready
(as defined below).  Set forth in the CFSB Disclosure Statement are copies
of all letters and responses between CFSB or CFSB's subsidiaries and their
vendors relating to such compliance matters.  The cost of achieving Year
2000 Readiness for any Year 2000 Assets that are not Year 2000 Ready would
not have a Material Adverse Effect on CFSB or CFSB's subsidiaries.  No
representation is made relating to the compatibility of the technology used
by CFSB or CFSB's subsidiaries with that used by Old Kent or with respect
to the cost of integrating the technology of CFSB or CFSB's subsidiaries
with that used by Old Kent.  "YEAR 2000 ASSETS" means all buildings,
plants, structures, machinery, equipment, software, hardware, computer
systems and other property owned, leased, licensed or used by CFSB or
CFSB's subsidiaries in their business.  "YEAR 2000 READY" means that the
Year 2000 Asset accurately processes and handles date and time data, in-
cluding but not limited to performing all leap year calculations and calcu-
lating, comparing and sequencing during and between the years 1999 and 2000
and all other years, and will not malfunction, cease to function or provide
invalid or incorrect results or data as a result of date or time data,
including when a Year 2000 Asset is used in combination with or is inter-
facing with any other Year 2000 Asset or with any other asset or informa-
tion technology.



                                      -35-


     4.37  ACCOUNTING AND TAX TREATMENT.  Neither CFSB nor, to its knowl-
edge, any of its affiliates, has taken or agreed to take any action or
knows of any reason that, with respect to CFSB and its affiliates, would
prevent Old Kent from accounting for the business combination to be ef-
fected by the Merger as a pooling-of-interests.  CFSB is aware of no reason
why the Merger will fail to qualify as a reorganization under Section
368(a) of the Internal Revenue Code.

     4.38  TRUE AND COMPLETE INFORMATION.  No schedule, statement, list,
certificate, or other information furnished or to be furnished by CFSB in
connection with this Plan of Merger, including the CFSB Disclosure State-
ment, contains or will contain any untrue statement of a material fact, or
omits or will omit to state a material fact necessary to make the state-
ments contained therein, in light of the circumstances in which they are
made, not misleading.


                   ARTICLE V - COVENANTS PENDING CLOSING

     Subject to the terms and conditions of this Plan of Merger, CFSB and
Old Kent further agree that:

     5.1  DISCLOSURE STATEMENTS; ADDITIONAL INFORMATION.

               5.1.1  FORM AND CONTENT.  Each party's Disclosure Statement shall
     contain appropriate references and cross-references with respect to
     disclosures, and appropriate identifying markings with respect to
     documents, that pertain to one or more sections or articles of this
     Plan of Merger.

               5.1.2  UPDATE.  Not less than six business days prior to the
     Closing, each party shall deliver to the other an update to its Dis-
     closure Statement describing any material changes and containing any
     new or amended documents, as specified below, that are not contained
     in its Disclosure Statement as initially delivered.  This update shall
     not cure any breach of a representation or warranty occurring at the
     time of execution of this Plan of Merger.

               5.1.3  CERTIFICATION.  Each party's Disclosure Statement and its
     update shall each be certified on its behalf by its chief executive
     officer and its chief financial officer (or, in the case of Old Kent,
     such other executive officer(s) as may be appropriate) that such Dis-
     closure Statement contains no untrue statement of a material fact, or
     fails to omit to state a material fact necessary to make the state-
     ments contained therein, in light of the circumstances in which they
     are made, not misleading.



                                      -36-


               5.1.4  CFSB'S SCHEDULE OF ADDITIONAL INFORMATION.  CFSB shall
     prepare and, within 45 days after the execution of the Plan of Merger,
     deliver to Old Kent two copies of the Schedule of Additional Informa-
     tion attached as EXHIBIT C.  The Schedule of Additional Information
     shall contain the information described in EXHIBIT C with appropriate
     references and cross-references with respect to disclosures and appro-
     priate identifying marking with respect to documents.  In addition,
     the Schedule of Additional Information shall contain true and correct
     copies of each and every document specified in EXHIBIT C.

     5.2  CHANGES AFFECTING REPRESENTATIONS.  While this Plan of Merger is
in effect, if either Old Kent or CFSB becomes aware of any facts or of the
occurrence or impending occurrence of any event that (a) would cause one or
more of the representations and warranties it has given in Article III or
IV, respectively, subject to the exceptions contained in the CFSB Disclo-
sure Statement or the Old Kent Disclosure Statement, respectively, to be-
come untrue or incomplete, or (b) would have caused one or more of such
representations and warranties to be untrue or incomplete had such facts
been known or had such event occurred prior to the execution of this Plan
of Merger, then such party (the "NOTIFYING PARTY") shall immediately give
detailed written notice of such discovery or change, including a detailed
description of the underlying facts or events, to the other party; and
unless waived by the other party in writing, the Notifying Party shall use
all reasonable efforts to take remedial or preventative action, if possi-
ble, in order that such representations and warranties will be true and
complete at the Closing.  No remedial action taken by a Notifying Party
shall be deemed to cure a breach of any representation or warranty given by
the Notifying Party in this Plan of Merger, unless such cure is to the
reasonable satisfaction of the other party.

     5.3  CONDUCT OF BUSINESS PENDING THE EFFECTIVE TIME--CFSB.  CFSB
agrees that, until the Effective Time, except as consented to in writing by
Old Kent or as otherwise provided in this Plan of Merger, CFSB shall, and
it shall cause each of its subsidiaries to:

     property only in the usual, regular, and ordinary course and not oth-
     erwise, in substantially the same manner as prior to the execution of

     ness or property.

     would cause CFSB's representations and warranties to become untrue



                                      -37-

     Old Kent has been notified of such contest.

               5.3.4  NO AMENDMENTS.  Make no change in its Certificate of In-

     property and assets in their present state of repair, order and condi-

               5.3.9  INSURANCE POLICIES.  Use all reasonable efforts to main-
     tain and keep in full force and effect insurance coverage, so long as

     risks and losses, and with such self-insurance requirements as are
     presently in force.

               5.3.10  CHARGE-OFFS.  Charge off loans and maintain its reserve
     for loan and lease losses, in each case in a manner in conformity with


                                      -38-


     the prior practices of CFSB and CFSB Bank and applicable industry,
     regulatory, and accounting standards.

               5.3.11  POLICIES AND PROCEDURES.  Make no material change in any

     ment, or other capital asset in excess of $50,000 individually or in

     the CFSB Disclosure Statement.

               5.3.22  NEW SERVICE ARRANGEMENTS.  Take no action to enter into,
     or commit to enter into, any agreement for trust, consulting, profes-
     sional, or other services to CFSB or any of CFSB's subsidiaries that

     ing pursuant to prior commitments or plans made by CFSB or CFSB Bank
     that are disclosed in the CFSB Disclosure Statement.

     5.4  APPROVAL OF PLAN OF MERGER.  As soon as practicable after this
Plan of Merger has been executed and delivered and the Registration State-
ment has become effective, CFSB shall submit this Plan of Merger to its

                                      -40-


stockholders for approval and adoption at a meeting properly called, no
ticed, and held for that purpose (the "STOCKHOLDERS' MEETING").

               5.4.1  BOARD RECOMMENDATION.  Except in the case of a "Fiduciary
     Event" (as defined below) at the Stockholders' Meeting and in any
     proxy materials used in connection with the meeting, the board of
     directors of CFSB shall recommend that its stockholders vote for ap-
     proval and adoption of this Plan of Merger.  All actions taken in
     connection with the solicitation of proxies for and the voting of
     shares of CFSB Common Stock held by or through the CFSB Employee Stock
     Ownership Plan (the "ESOP") shall be done in a manner that complies
     with all standards and guidelines issued by the United States Depart-
     ment of Labor.

               5.4.2  FIDUCIARY EVENT.   A "FIDUCIARY EVENT" shall have occurred
     when the board of directors of CFSB has (a) received in writing a
     "Superior Proposal" (as defined below), which is then pending, (b)
     determined in good faith (after consultation with independent legal
     counsel) that the failure to so withdraw, modify, or change its recom-
     mendation would cause the board of directors of CFSB to breach its
     fiduciary duties to CFSB's stockholders under applicable law, and (c)
     determined to accept and recommend the Superior Proposal to the stock
     holders of CFSB.

               5.4.3  SUPERIOR PROPOSAL.  A "SUPERIOR PROPOSAL" means any bona
     fide unsolicited Proposal (as defined in Section 5.9.2 (COMMUNICATION
     OF OTHER PROPOSALS)) made by a third party on terms that the board of
     directors of CFSB determines in its good faith judgment, based upon
     the written advice of Feldman Financial or such other a financial
     advisor of nationally recognized reputation, to be more financially
     favorable to CFSB's stockholders than the Plan of Merger.

               5.4.4  NOTICE.   CFSB agrees that it shall notify Old Kent at
     least three business days prior to taking any action with respect to
     such Superior Proposal or taking any action with respect to the with-
     drawal, modification, or change of its recommendation to stockholders
     for adoption of this Plan of Merger.  Notwithstanding anything to the
     contrary contained in this Plan of Merger, any withdrawal, modifica-
     tion, or change of recommendation upon a Fiduciary Event in accordance
     with the provisions of this Section shall not constitute a breach of
     this Plan of Merger by CFSB.

     5.5  REGULAR DIVIDENDS.  CFSB shall not declare, set aside, pay or
make any dividend or other distribution or payment (whether in cash, stock,
or property) with respect to, or purchase or redeem, any shares of the
capital stock other than the regular 10 percent stock dividend on dates
corresponding to the historical declaration and payment dates and regular


                                      -41-


quarterly cash dividends per share on CFSB Common Stock payable on the
regular historical payment dates, all in a manner consistent with CFSB's
past dividend practice.  Old Kent and CFSB agree that they will cooperate
to assure that, during any calendar quarter, there shall not be a duplica-
tion of payment of dividends to stockholders of CFSB.  Notwithstanding the
above, if and to the extent that the payment of a dividend in the manner
provided in this Section would, under GAAP or the rules, regulations, or
interpretations of the SEC or its staff, disqualify the Merger for pooling-
of-interests accounting treatment, that dividend shall not be paid, but an
equitable adjustment shall be made to the Exchange Ratio for the amount of
the dividend not paid.  If the customary payment date for the next regular
cash dividend payable after the Effective Time of Old Kent Common Stock as
the Surviving Corporation which is eligible to be received by the former
holders of CFSB Common Stock is more than 90 days after the payment date of
the last regular cash dividend paid or to be paid on CFSB Common Stock
prior to the Effective Time (such number of days over 90 days being the
"DIVIDEND LAG PERIOD"), then CFSB may declare and set aside immediately
prior to the Effective Time, and may pay at a date it may select in its
discretion, a "SPECIAL PRO-RATA DIVIDEND" pursuant to this Section.  Any
such Special Pro-rata Dividend shall be payable in cash, and shall not
exceed an amount per share that is the product of (i) the amount of the
dividend permitted to be paid by CFSB pursuant to this Section 5.5, multi-
plied by (ii) a fraction, the numerator of which is the Dividend Lag Period
and the denominator of which is 90 days.

     5.6  DATA PROCESSING AND RELATED CONTRACTS.  Until the Effective Time,
CFSB shall not enter into any new data processing agreement without the
consent of Old Kent (which consent shall not be unreasonably withheld or
delayed if such agreement is necessary for CFSB to conduct business in the
ordinary course) and shall advise Old Kent of all anticipated renewals or
extensions of existing data processing service agreements, data processing
software license agreements, and data processing hardware lease agreements
with independent vendors.  CFSB agrees to cooperate with Old Kent in nego-
tiating with those vendors the length of any extension or renewal term of
those agreements, which, unless otherwise agreeable with Old Kent, shall
not exceed one year from the date of renewal.  CFSB agrees to send to each
vendor, as and when due, such notices of nonrenewal as may be necessary or
appropriate under the terms of the applicable agreements to prevent those
agreements from automatically renewing for a term of more than one year
from the date of renewal, except as otherwise agreed between CFSB and Old
Kent.

     5.7  AFFILIATES -- COMPLIANCE WITH ACCOUNTING AND SECURITIES RULES.

               5.7.1  CFSB AFFILIATES.  CFSB shall use its best efforts to cause
     each director, executive officer, and other person who is an "affili-
     ate" (for purposes of (a) Rule 145 under the Exchange Act, and (b)
     qualifying the Merger for pooling-of-interests accounting treatment)

                                      -42-


     of CFSB to deliver to Old Kent, as soon as practicable after the date
     of this Plan of Merger, and prior to the date of the Stockholders'
     Meeting, a written agreement, in the form of EXHIBIT D (the "CFSB
     AFFILIATE AGREEMENTS").  CFSB shall provide a list of such affiliates
     within five  days of its execution of this Plan Merger and shall up
     date such list as necessary upon the reasonable request of Old Kent.
     Old Kent shall use its best efforts to publish as promptly as reason-
     ably practical but in no event later than 30 days after the end of the
     first full month after the Effective Time in which there are at least
     30 days of post-Merger combined operations (which month may be the
     month in which the Effective Time occurs), combined sales and net
     income figures as contemplated by and in accordance with the terms of
     SEC Accounting Series Release No. 135.

               5.7.2  OLD KENT AFFILIATES.  Old Kent shall use all reasonable
     efforts to cause each director, executive officer, and other person
     who is an "affiliate" (for the purpose of qualifying the Merger for
     pooling-of-interests accounting treatment) of Old Kent, as soon as
     practicable after the date of this Plan of Merger, and prior to the
     date of the Stockholders' Meeting, to execute and deliver a written
     agreement under which such affiliate agrees not to sell, pledge,
     transfer, or otherwise dispose of his or her Old Kent Common Stock
     during any period that any such disposition would, under GAAP or the
     rules, regulations, or interpretations of the SEC or its staff, dis-
     qualify the Merger for pooling-of-interests accounting treatment.

     5.8  INDEMNIFICATION AND INSURANCE.

               5.8.1  INDEMNIFICATION.  Following the Effective Time, Old Kent
     shall indemnify, defend and hold harmless the directors and officers
     of CFSB and its subsidiaries (each an "INDEMNIFIED PARTY") against all
     costs or expenses (including reasonable attorneys' fees), judgments,
     fines, losses, claims, damages or liabilities or amounts paid in set-
     tlement incurred in connection with any claim, action, suit or pro-
     ceeding, whether civil, criminal, administrative or investigative
     (collectively, "CLAIMS"), arising out of actions or omissions occur-
     ring at or prior to the Effective Time, including, but not limited to,
     the Merger, regardless of whether such Claim is asserted before, at or
     after the Effective Time, to the fullest extent that CFSB or its sub-
     sidiaries is permitted to indemnify (and advance expenses to) its
     directors and officers under applicable state or federal law in effect
     as of the date hereof or as amended applicable to a time before the
     Effective Time or the Certificate of Incorporation or By-laws of CFSB
     or its subsidiaries as in effect as of the date hereof.  Old Kent may
     pay expenses in advance of the final disposition of any such action or
     proceeding to each Indemnified Party to the full extent permitted by
     applicable state or federal law in effect as of the date hereof or as
     amended applicable to a time before the Effective Time upon receipt of

                                      -43-


     any undertaking required by applicable law.  Old Kent shall ensure, to
     the extent permitted under applicable law, that all limitations of
     liability existing in favor of the Indemnified Parties as provided in
     CFSB's Certificate of Incorporation, as in effect as of the date
     hereof, or allowed under applicable state or federal law as in effect
     as of the date hereof or as amended applicable to a time before the
     Effective Time, with respect to claims or liabilities arising from
     facts or events existing or occurring before the Effective Time (in-
     cluding, without limitation, the transactions contemplated hereby),
     shall survive the Merger.

               5.8.2  INSURANCE.  Old Kent shall use all reasonable efforts to
     cause the persons serving as officers and directors of CFSB immedi-
     ately prior to the Effective Time to be covered for a period of at
     least six years from the Effective Time by the directors' and offi-
     cers' liability insurance policy maintained by CFSB (provided that Old
     Kent may substitute therefor policies of at least the same coverage
     and amounts containing terms and conditions that are not materially
     less advantageous than such policy) with respect to acts or omissions
     occurring prior to the Effective Time that were committed by such
     officers and directors in their capacity as such; provided, that in no
     event shall Old Kent be required to spend more than $140,000 (the
     "INSURANCE AMOUNT") to maintain or procure insurance coverage pursuant
     hereto.  If Old Kent does not advise CFSB in writing at least 30 days
     prior to the Closing that it has procured such coverage for at least
     six years or agrees to do so without regard to the Insurance Amount,
     CFSB shall be permitted (after giving Old Kent three business days
     prior written notice and an additional two business day period to
     purchase such coverage), in lieu of receiving the foregoing insurance
     coverage, to procure tail coverage for past acts and omissions for a
     single premium amount not in excess of the Insurance Amount.

               5.8.3  ENFORCEMENT.  The obligation of Old Kent provided under
     Sections 5.8.1 and 5.8.2 are intended to be enforceable against Old
     Kent directly by the Indemnified Parties and shall be binding on all
     respective successors and permitted assigns of Old Kent.

     5.9  EXCLUSIVE COMMITMENT.  Neither Old Kent nor any of Old Kent's
subsidiaries, nor any of their directors, officers, employees, investment
bankers, representatives, or agents, shall take any action inconsistent
with the intent to consummate the Merger upon the terms and conditions of
this Plan of Merger.  Except as provided below, neither CFSB nor any of
CFSB's subsidiaries, nor any of their directors, officers, employees, in-
vestment bankers, representatives, or agents, shall take any action incon-
sistent with the intent to consummate the Merger upon the terms and condi-
tions of this Plan of Merger.  Without limiting the foregoing:

               5.9.1  NO SOLICITATION.  Neither CFSB nor any of CFSB's subsid-
     iaries, nor any of their respective directors, officers, employees,
     investment bankers, representatives, or agents, shall directly or
     indirectly invite, initiate, solicit or encourage, or, unless a Fidu-
     ciary Event  has occurred and continues (or a Superior Proposal has
     been presented and such Superior Proposal would otherwise give rise to
     a Fiduciary Event except that the board of directors of CFSB, at that
     time, has yet to determine to accept and recommend the Superior Pro-
     posal to the stockholders of CFSB), negotiate (which terms shall not
     include a request for additional information in response to a Proposal
     that is necessary to determine whether the Proposal is a Superior
     Proposal, which shall be permitted hereby) with any other party, any
     proposals, offers, or expressions of interest concerning any tender
     offer, exchange offer, merger, consolidation, sale of shares, sale of
     assets, or assumption of liabilities not in the ordinary course, or
     other business combination involving CFSB or any of CFSB's subsidiar-
     ies other than the Merger (a "BUSINESS COMBINATION").

               5.9.2  COMMUNICATION OF OTHER PROPOSALS.  CFSB shall cause writ-
     ten notice to be delivered to Old Kent promptly upon receipt of any
     solicitation, offer, proposal, or expression of interest (a "PRO
     POSAL") concerning a Business Combination.  Such notice shall contain
     the material terms and conditions of the Proposal to which such notice
     relates and shall contain, unless a Fiduciary Event has occurred and
     continues or a request for additional information which the CFSB board
     of directors has determined is necessary to fulfill its fiduciary
     duties is pending, a copy of CFSB's unequivocal rejection of the Pro-
     posal in the form actually delivered to the person from whom the Pro-
     posal was received.  Thereafter, CFSB shall promptly notify Old Kent
     of any material changes in the terms, conditions, and status of any
     Proposal.

               5.9.3  FURNISHING INFORMATION.   Unless a Fiduciary Event has
     occurred and continues (or a Superior Proposal has been presented and
     such Superior Proposal would otherwise give rise to a Fiduciary Event
     except that the board of directors of CFSB, at that time, has yet to
     determine to accept and recommend the Superior Proposal to the stock-
     holders of CFSB), neither CFSB nor any of CFSB's subsidiaries, nor any
     of their respective directors, officers, employees, investment bank
     ers, representatives, or agents, shall furnish any nonpublic informa-
     tion concerning CFSB to any person who is not affiliated or under
     contract with CFSB or Old Kent, except as required by applicable law
     or regulations.

For the purposes of this Section, any breach of this Section by an execu-
tive officer or director of CFSB in his or her individual capacity shall be
deemed to be a breach by CFSB.

pare and file within 45 days after the date of this Plan of Merger with the
Federal Reserve Board, OTS, and each other regulatory agency having juris-

their respective subsidiaries to permit, full access to their respective
properties, books, and records at reasonable times and without undue inter-
ference with normal business operations; (b) use reasonable efforts to
cause its and each of respective subsidiaries' officers, directors, employ-
ees, accountants, and attorneys to cooperate fully, for the purpose of

party's officers, attorneys, accountants, and representatives; and (c)
furnish to the other, upon reasonable request, any information reasonably
requested respecting its and each of its subsidiaries' properties, assets,
business, and affairs.  Each party acknowledges that certain information
may not be disclosed by the other without the prior written consent of
persons not affiliated with that party.  If such information is requested,
then the other party shall use reasonable efforts to obtain such prior
consent and shall not be required to disclose such information unless and
until such prior consent has been obtained.  In the event of termination of
this Plan of Merger, Old Kent and CFSB each agree to promptly return to the
other party or to destroy all written materials furnished to it by the
other party and the other party's subsidiaries, and all copies, notes, and
summaries of such written materials.  Old Kent and CFSB each agree to pre-
serve intact all such materials that are returned to them and to make such
materials reasonably available upon request or subpoena for a period of not
less than six years from the termination of this Plan of Merger.

     5.14  CONFIDENTIALITY.  Except as provided below, Old Kent and CFSB
each agree:

               5.14.1  TREATMENT; RESTRICTED ACCESS.  All information furnished
     to the other party pursuant to this Plan of Merger shall be treated as
     strictly confidential and shall not be disclosed to any other person,
     natural or corporate, except for its employees, attorneys, accoun-
     tants, regulators, and financial advisers who are reasonably believed
     to have a need for such information in connection with the Merger or
     except as required by law.

               5.14.2  NO OTHER USE.  Neither party shall make any use, other
     than related to the Merger, of any information it may come to know as
     a direct result of a disclosure by the other party, its subsidiaries,
     directors, officers, employees, attorneys, accountants, or advisers or
     that may come into its possession from any other confidential source
     during the course of its investigation.

               5.14.3  EXCEPTED INFORMATION.  The provisions of this
     Section shall not preclude Old Kent or CFSB, or their respective sub-
     sidiaries, from using or disclosing information that is readily ascer-
     tainable from public information or trade sources, known by it before
     the commencement of discussions between the parties or subsequently
     developed by it or its subsidiaries independent of any investigation
     under this Plan of Merger, received from any other person who is not
     affiliated with a party and who is not under any obligation to keep
     such information confidential, or reasonably required to be included
     in any filing or application required by any governmental or regula-
     tory agency.


                                      -47-


               5.14.4  PROHIBIT INSIDER TRADING.  Old Kent and CFSB shall each
     take responsible steps to assure that any person who receives
     nonpublic information concerning the Merger or the other party will
     treat the information confidentially as provided in this Section and
     not directly or indirectly buy or sell, or advise other persons to buy
     or sell, the other party's stock until such information is properly
     disclosed to the public.

     5.15  ENVIRONMENTAL INVESTIGATION.  Old Kent shall be permitted to
conduct an environmental assessment of each parcel of CFSB's Real Property
and, at Old Kent's option, any other real estate acquired by any of CFSB's
subsidiaries in satisfaction of a debt previously contracted.  As to each
such property:

               5.15.1  PRELIMINARY ENVIRONMENTAL ASSESSMENTS.  Old Kent may, at
     its expense, engage an environmental consultant to conduct a prelimi-
     nary ("PHASE I") assessment of the property or, at its option, rely
     upon any Phase I assessment of the property obtained by CFSB, or any
     predecessor or company acquired by CFSB, that is recertified to Old
     Kent as of a recent date.  CFSB and CFSB's subsidiaries shall provide
     reasonable assistance, including site access and a knowledgeable con-
     tact person, to the consultant for purposes of conducting the Phase I
     assessments.

               5.15.2  ENVIRONMENTAL RISKS.  If there are any facts or condi-
     tions identified in a Phase I assessment that Old Kent believes could
     pose a current or future risk of a material liability, interference
     with use, or diminution of value of the property, then Old Kent shall
     identify that risk to CFSB, identify the facts or conditions underly-
     ing that risk, and provide CFSB with a copy of the Phase I assessment
     for that property (an "ENVIRONMENTAL RISK").

               5.15.3  PHASE II AND III WORK.  Old Kent may obtain one or more
     estimates of the proposed scope of work and cost of any further envi-
     ronmental investigation, remediation, or other follow-up work it rea-
     sonably considers necessary or appropriate to assess and, if necessary
     under Environmental Laws, remediate an Environmental Risk ("PHASE II
     AND III WORK").  Old Kent shall provide copies of those estimates to
     CFSB.  The fees and expenses of any Phase II and III Work shall be
     paid by CFSB.  Old Kent and CFSB shall cooperate in the review, ap-
     proval, and implementation of all work plans for Phase II and III
     Work. All work plans for any Phase II and III Work shall be mutually
     satisfactory to Old Kent and CFSB.  Mutually agreed upon Phase II and
     III Work shall be undertaken and completed as quickly as possible and
     shall be completed prior to the Closing.

               5.15.4  OLD KENT'S TERMINATION RIGHTS.  If (a) Old Kent and CFSB
     are unable to agree upon a course of action to complete any Phase II

                                      -48-


     and III Work and/or a mutually acceptable modification to this Plan of
     Merger, and (b) Old Kent cannot be reasonably assured that the after-
     tax cost of the sum of (i) the actual cost of all investigative and
     remedial or other corrective actions or measures taken pursuant to
     Section 5.15.3 (PHASE II AND III WORK); (ii) the estimated cost of all
     investigative actions and remedial or other corrective actions or
     measures not undertaken but required by Environmental Laws, or neces-
     sary to avoid future exposure to material liability under Environmen-
     tal Laws; and (iii) all diminutions of the value of such properties;
     in the aggregate will not exceed $3,000,000, then Old Kent may termi-
     nate this Plan of Merger as provided in Section  8.3.2 (ENVIRONMENTAL
     RISKS).

     5.16  ESOP.  The ESOP shall be terminated effective as of the Effec-
tive Time.  Prior to its termination, the ESOP shall be amended to provide
that no employees of Old Kent shall be eligible to participate, that there
shall be no new participants in the plan on or after the Closing, that upon
termination the Trustee shall pay off the outstanding balance owed by the
ESOP under the loan agreement dated as of April 25, 1994, between the ESOP
and CFSB (the "ESOP LOAN AGREEMENT"), and that any assets left in the sus-
pense account after repayment of the loan will be allocated among the par-
ticipants of the ESOP in accordance with the terms of the ESOP in a manner
consistent with the Internal Revenue Code.  Upon receipt of a favorable IRS
determination letter with respect to the termination (which shall be pre-
pared by Old Kent and its counsel with the participation and cooperation of
CFSB and its counsel), the participants in the ESOP will have the option to
transfer or roll over their ESOP accounts into the Old Kent Thrift Plan.

     5.17  TERMINATION OF 401(K) PLAN.  Upon request by Old Kent, CFSB
shall, and shall cause CFSB Bank to, take all action that is necessary and
appropriate in the judgment of Old Kent to terminate the CFSB Bank Employ-
ees' Deferred Savings Plan (the "401(K) PLAN") on a mutually agreed date
that is as close as practicable to, but not more than 30 days before, the
Effective Time.

     5.18  EMPLOYMENT AMENDMENTS.  CFSB shall cause CFSB Bank, within 30
days after the date of this Plan of Merger, to obtain amendments (in the
form previously agreed to by Old Kent and CFSB) to two existing employment
agreements with its senior officers, as specified by Old Kent, providing
for, among other things, mutually agreeable no-compete and non-solicitation
covenants from those two employees, which shall only become effective upon
consummation of the Merger at the Effective Time (the "EMPLOYMENT AMEND-
MENTS").

     5.19  ACCOUNTING AND TAX TREATMENT.  During the Term of this Plan of
Merger, Old Kent and CFSB each agree not to take any action that would
adversely affect the ability of Old Kent to treat the Merger as a pooling-
of-interests for accounting purposes or as a "reorganization" within the

                                      -49-


meaning of Section 368(a) of the Internal Revenue Code; provided, that
nothing in this Plan of Merger shall limit Old Kent's ability to exercise
its rights under the Option Agreement.  Old Kent and CFSB each agree to
take such action as may be reasonably required to negate the impact of any
past actions, if any, that might adversely impact the ability of Old Kent
to treat the Merger as a pooling-of-interests.

     5.20  PUBLIC ANNOUNCEMENTS.  Old Kent and CFSB shall cooperate with
each other in the development and distribution of all news releases and
other public information disclosures with respect to this Plan of Merger,
except as may be otherwise required by law, and neither Old Kent nor CFSB
shall issue any news releases with respect to this Plan of Merger or the
Merger unless such news releases have been mutually agreed upon by the
parties, except as required by law.

     except (a) as expressly contemplated or permitted by this Plan of
     Merger, (b) for representations and warranties relating to a time or
     times other than the Closing that were or will be true and correct at
     such time or times, and (c) where the failure or failures of such
     representations and warranties to be so true and correct, individually

     Adverse Effect.

               6.1.2  COMPLIANCE WITH AGREEMENTS.  CFSB shall have performed and
     complied with all agreements, conditions, and covenants required by
     this Plan of Merger to be performed or complied with by CFSB prior to

such approvals, consents, authorizations, and licenses of all regulatory
and other governmental and self-regulatory authorities having jurisdiction
as may be required to permit the performance by CFSB and Old Kent of their

counsel, reasonably satisfactory in form and substance, that Old Kent shall
use reasonable efforts to obtain.  The tax opinion shall be supported by

shall be substantially to the effect that:

               6.7.1  REORGANIZATION.  The Merger of CFSB with and into Old Kent
     will constitute a reorganization within the meaning of Section 368(a)

ately preceding the Closing; and (b) with respect to the secretary's cer-
tification, the number of shares of CFSB Common Stock, if any, that are
issuable on or after that date, all in such form as Old Kent may reasonably
request.

dence of the consents or other waivers of any material rights and the
waiver of the loss of any material rights that may be triggered by the
change of control of CFSB upon consummation of the Merger under the Desig-
nated Contracts and any other agreement, contract, mortgage, deed of trust,
lease, commitment, indenture, note, or other instrument, under which the

Effect on CFSB; all in form and substance reasonably satisfactory to Old
Kent.

dressed to CFSB, from CFSB's independent accountants, as of a date reason-
ably approximate to the date of the Closing, to the effect that, as of such
date, CFSB is eligible to participate in a pooling-of-interests combination

substance, to the effect that (based in part on the letter from CFSB's
independent accountants) the Merger should be treated as a pooling-of-in-
terests for accounting and financial reporting purposes, subject to satis-
faction of post-Merger conditions.

     6.12  NO DEFAULT UNDER ESOP LOAN AGREEMENT.  CFSB shall have obtained
and delivered to Old Kent such consents, amendments, or supplemental agree-
ments, all in form and substance reasonably satisfactory to Old Kent, nec-

sel.  The tax opinion shall be supported by one or more fact certificates

     Stock received by stockholders of CFSB will, in each instance, include

of Merger by either CFSB or Old Kent as provided in this Article, this Plan
of Merger shall forthwith become void and have no effect, and none of

officers or directors of any of them shall have any liability of any nature

hereby (other than the Option Agreement), except that (a) the Option Agree-
ment and Sections 5.15 (CONFIDENTIALITY), 8.5 (EFFECT OF TERMINATION), 9.2
(NONSURVIVAL OF REPRESENTATIONS, WARRANTIES, AND AGREEMENTS), and 9.4 (EX-
PENSES), shall survive any termination of this Plan of Merger, and (b)
notwithstanding anything to the contrary contained in this Plan of Merger,



                                      -56-

ties or damages arising out of its breach of any provision of this Plan of
Merger.


                        ARTICLE IX - MISCELLANEOUS

     Subject to the terms and conditions of this Plan of Merger, Old Kent
and CFSB further agree as follows:

     9.1  "MATERIAL ADVERSE EFFECT" DEFINED.  As used in this Plan of
Merger, the term "MATERIAL ADVERSE EFFECT" means any change or effect that,
individually or when taken together with all other such changes or effects
that have occurred prior to the date of determination of the occurrence of
the Material Adverse Effect, is or is reasonably likely to have a material
negative impact on (a) the business, assets, financial condition, results
of operations, or value of Old Kent and its subsidiaries, taken as a whole,
or, as the case may be, CFSB and CFSB Bank, taken as a whole; or (b) the
ability of Old Kent or CFSB, as the case may be, to satisfy the applicable
closing conditions or consummate the Merger or perform its obligations
under the Option Agreement.  Notwithstanding the above, the impact of the
following shall not be included in any determination of a Material Adverse
Effect:  (a) changes in GAAP, generally applicable to financial institu-
tions and their holding companies; (b) actions and omissions of a party (or
any of its subsidiaries) taken with the prior written consent of the other
party; (c) changes in economic conditions (including changes in the level
of interest rates) generally affecting financial institutions; and (d) fees
and expenses reasonably related to this transaction (such as any additional
insurance coverages, employment and consulting services, legal, accounting,
and investment banking fees and expenses, and severance and retention pro-
visions).

     9.2  NONSURVIVAL OF REPRESENTATIONS, WARRANTIES, AND AGREEMENTS.  None
of the representations, warranties, covenants and agreements in this Plan
of Merger or in any other agreement or instrument delivered pursuant to
this Plan of Merger, including any rights arising out of any breach of such
representations, warranties, covenants, and agreements, shall survive the
Effective Time, except for the Option Agreement, Affiliate Agreements,
Employment Amendments, and those covenants and agreements contained herein
and therein that, by their terms, apply or are to be performed in whole or
in part after the Effective Time.

     9.3  AMENDMENT.  Subject to applicable law, this Plan of Merger may be
amended, modified, or supplemented by, and only by, written agreement of
Old Kent and CFSB, or by the respective officers thereunto duly authorized,
at any time prior to the Effective Time.



                                      -57-


     9.4  EXPENSES.  Except as otherwise provided in this Plan of Merger,
CFSB and Old Kent shall each pay its own expenses incident to preparing
for, entering into, and carrying out this Plan of Merger, and incident to
the consummation of the Merger.  Each party shall pay the fees and expenses
of any investment banker engaged by that party.  The costs of all filing
fees pertaining to the Registration Statement shall be paid by Old Kent.
The costs of printing and mailing the Prospectus and Proxy Statement shall
be paid by CFSB.

     9.5  SPECIFIC ENFORCEMENT.  The parties each agree that, consistent
with the terms and conditions of this Plan of Merger, in the event of a
breach by a party to this Plan of Merger, money damages may be inadequate
and not susceptible of computation because of the unique nature of CFSB,
CFSB Bank, and the Merger.  Therefore, the parties each agree that a fed-
eral or state court of competent jurisdiction shall have authority, subject
to the rules of law and equity, to specifically enforce the provisions of
this Plan of Merger by injunctive order or such other equitable means as
may be determined in the court's discretion.

     9.6  JURISDICTION; VENUE; JURY.  Old Kent and CFSB each agree to the
jurisdiction and venue of any state or federal court located in Ingham
County or Kent County, Michigan.  Old Kent and CFSB each hereby waive their
right to a trial by jury.

     9.7  WAIVER.  Any of the terms or conditions of this Plan of Merger
may be waived in writing at any time by action taken by the board of direc-
tors of a party, a duly authorized committee thereof, or a duly authorized
officer of such party.  The failure of any party at any time or times to
require performance of any provision of this Plan of Merger shall in no
manner affect such party's right at a later time to enforce the same provi-
sion.  No waiver by any party of any condition, or of the breach of any
term, covenant, representation, or warranty contained in this Plan of
Merger, whether by conduct or otherwise, in any one or more instances shall
be deemed to be or construed as a further or continuing waiver of any such
condition or breach, or as a waiver of any other condition or of the breach
of any other term, covenant, representation, or warranty.

     9.8  NOTICES.  All notices, requests, demands, and other communica-
tions under this Plan of Merger shall be in writing and shall be deemed to
have been duly given if delivered or sent and received by a fax transmis-
sion (if receipt by the intended recipient is confirmed by telephone and if
hard copy is delivered by overnight delivery service the next day), a hand
delivery, or a nationwide overnight delivery service (all fees prepaid) to
the following addresses:
