31, 1993, and by $89.1 million, or 19%, over September 30, 1993.

During the nine months ended September 30, total deposits rose by $66.7
million, while loans increased by $21.9 million.  Because of the tremendous
deposit growth, the Corporation purchased a large amount of securities during
the year.

The following tables show the amortized cost and fair value of the
Corporation's security portfolios as of the dates indicated.  On the balance
sheet, investment securities (i.e., those which the Corporation has the ability
and intent to hold to maturity) are stated at cost, adjusted for amortization
of premium and accretion of discount.  Securities available for sale are
reported at fair value beginning January 1, 1994.  Prior to that, securities
available for sale had been carried at the lower of amortized cost or fair
value.

Effective January 1, 1994, the Corporation adopted Statement of Financial
Accounting Standards No. 115, "Accounting for Certain Investments in Debt and
Equity Securities."  This statement requires the classification of debt and
equity securities into three categories; investment, trading, or available for
sale.  As noted earlier, investment securities are carried at amortized cost,
and no gains or losses are recorded until realized.  Securities available for
sale are carried at fair value.  Unrealized gains and losses on securities
available are excluded from earnings, but are reported (net of tax) as a
separate component of stockholders' equity.  Securities that are bought and
held principally to sell them in the near term would be classified as trading
securities, and reported at fair value, with unrealized gains and losses
charged to earnings.  Since the Corporation does not engage in the short term
buying and resale of securities, management has not placed any securities in
the trading category, and does not expect to do so in the future.

As of September 30, 1994 the Corporation has recorded an unrealized loss of
$203,000 on securities available for sale.  An after-tax reduction of $135,000
has been recorded in the stockholders' equity section of the balance sheet.

During 1994, securities to be held to maturity have increased by 55%, or $43.6
million, to $123.7 million at September 30, 1994.  The largest increase during
this period came in the United States Government agency category, with an
increase of $17.8 million.  The security purchases were made as deposit growth
outpaced loan demand during the nine month period.  Investment securities have
increased by $46.6 million since the prior September 30.

Total loans increased by $21.9 million during the nine months ended September
30, 1994, and increased by $24.2 million since September 30, 1993.

Residential real estate loans rose by $4.3 million during the first nine months
of the year, due to a pick up in home mortgage lending.  During the twelve
months ended September 30, 1994, residential mortgage loans increased by 1%, or
$0.6 million.  The smaller increase was due to prepayment and refinancing
activity in the latter part of 1993.

Commercial loans have increased by $10.1 million during the nine months, to
$222.1 million at September 30.  Over the past year, commercial loans have
increased by 9%, or $17.7 million.  For both the nine and twelve month periods,
the majority of the increases came in fixed rate loans secured by commercial
mortgages, and tax-exempt fixed rate loans.  Many of the commercial mortgage
loans are for working capital purposes, for which the Bank has taken a mortgage
as security on the loan.

Installment loans increased by $7.6 million, or 14%, during the nine months
ended September 30, 1994, to $63.2 million.  The largest increases were in auto
and boat lending, aided by the Bank's successful "Loans-By-Phone" campaign,
launched in the spring.

The following table shows the components of nonperforming loans as of the dates
indicated, as well as the ratios of such loans to the total loan portfolio:

Loans are placed in nonaccrual status when, in the opinion of management,
serious uncertainty exists as to the ultimate collection of principal and
interest.  For the nine months ended September 30, 1994, $114,000 would have
been recorded in interest income for loans in nonaccrual status at September
30, 1994, assuming they had been current in accordance with the original terms
of the loans.  Interest received on nonaccrual loans is credited directly to
income.  Interest income of $10,000 was collected and included in net income
for the nine months ended September 30, for loans in nonaccrual status at
period end.

Nonaccrual loans at September 30, 1994, includes loans totaling $865,000 which
are secured by a commercial property which is in foreclosure.  The borrowers
have also personally guaranteed the loans.  The borrowers are in possession of
the property, and are attempting to bring the loan current within the
redemption period, which expires in December.  The Bank has bid on the
property, and expects to take possession if the loan is not brought back to
current status.  Loans for $213,000 to the same borrower were placed into
nonaccrual status in October, 1994, and the Bank has begun foreclosure
proceedings.  These loans are secured by a separate commercial property.  It
appears likely that the borrower will bring these loans current prior to the
redemption date.  Because of the uncertainty, it is difficult to estimate the
size of any potential losses.  The amount of loss in excess of amounts already
provided for in the allowance, if any, is not expected to have a material
effect on the Corporation's operating results, liquidity, or capital resources.

Also included in nonaccrual loans at September 30 are loans totaling $888,000
which are secured by two commercial properties.  The borrowers had been
frequently late making payments in the past, and are experiencing continued
cash flow problems.  The Bank is in the process of foreclosing on the
properties.  If the foreclosure is finalized, the Bank will seek offers to buy
the properties.  Any loss in excess of amounts reserved is not expected to have
a material effect on the Corporation's operating results, liquidity, or capital
resources.

In addition, management placed a commercial loan for $2.3 million in other real
estate on December 31, 1990, in accordance with accounting guidelines for
"in-substance" foreclosure loans.  The loan was for a commercial construction
project on which the Bank held a mortgage.  The property is currently carried
at the estimated net realizable value of the property, which was $2.6 million
at September 30, 1994.  The Corporation charged $390,000 to other real estate
expense for this property during the first nine months of 1994.  The Bank took
possession of the property in October, 1994.  In addition, the Bank agreed to
sell the property to new buyers.  The Bank has received a down payment, and is
in the process of closing a loan to the new owners.  The property has recently
been appraised at $2.8 million.  Because the new borrowers' initial investment
in the property is expected to be 10% of the sale amount, the new loan will be
carried on a full accrual basis, unless future conditions change.

In each quarter, or more frequently as necessary, management evaluates the
problems and potential losses in the loan portfolio.  The results of this
evaluation are reflected in the allowance and periodic provision for loan
losses.

At September 30, 1994, there were no significant loans that are not disclosed
above, where known information about possible credit problems of borrowers
causes management to have serious doubts as to the ability of the borrower to
comply with present loan repayment terms and which, in management's judgment,
may result in disclosure of such loans in the discussion above.  Furthermore,
management is not aware of any potential problem loans, except for those
described above, which could have a material effect on the Corporation's
operating results, liquidity, or capital resources.

The Bank grants loans to customers who live primarily in Macomb County and
metropolitan Detroit.  Although the Bank has a diversified loan portfolio, a
substantial portion of its debtors' ability to honor their loan agreements is
dependent upon the automotive industry.  Additionally, nearly all of the Bank's
residential real estate portfolio consists of loans for 1 to 4 family homes
located in Macomb County.

During the nine months ended September 30, 1994, total deposits increased by
15%, or $66.7 million, to $506.7 million.  The increase was paced by a $45.3
million increase in total demand deposits, primarily in commercial money market
accounts.  A large portion of this jump was a temporary deposit by a local
municipality.  After quarter end, this category moved closer to historical
levels.  Time deposits increased by $23.0 million, primarily in the new
"increasing rate" certificates.  For the twelve months ended September 30,
1994, total deposits have increased by 20%, or $85.4 million.  In this period,
demand deposits again led the way with a $59.7 million increase, while time
deposits increased by $27.0 million.

Following are selected capital ratios for the Corporation as of the dates
indicated, along with the minimum regulatory requirement for each item:

ANALYSIS OF CHANGES IN NET INTEREST INCOME

The following tables, presented on a fully tax-equivalent (FTE) basis, show the
dollar amount of changes in net interest income for each major category of
interest earning asset and interest bearing liability, and the amount of change
attributable to changes in average balances (volume) or average rates.
Variances that are attributable to BOTH volume and rate changes have been
allocated to the volume component.

</TABLE>

For the quarter ended September 30, 1994, net interest income, on a FTE basis
increased by 14%, or $768,000, over the same period one year ago.  This was due
to a significant rise in the volume of interest earning assets, especially in
securities.  On the liability side, an increase in time deposit volumes was
largely the result of higher rates.  This was partially offset by sharply lower
rates on savings deposits.  The larger asset volumes were boosted somewhat by
higher average rates on loans.  The net interest margin fell slightly in the
quarter, to 5.37%, compared with 5.41% for the same period one year ago.

For the nine months, FTE net interest income increased by $1.4 million, or 9%,
over the previous year-to-date.  Once again, the primary reason for the
increase was a large jump in the volume of securities.  The largest increases
were an $8.9 million increase in the average volume of Treasury securities, and
a $17.4 million increase in average agency securities.  Interest income from
securities rose significantly, in spite of lower average rates.  Interest
expense rose modestly by replacing long term debt with a less expensive
financing source (deposits) in the current year.

AVERAGE STATEMENTS OF CONDITION

The following tables, also presented on a FTE basis,  show  the Corporation's
consolidated average balances of assets, liabilities, and stockholders' equity;
the amount of interest income or interest expense and the average yield or rate
for each category of interest earning asset and interest bearing liability; the
net interest spread, and the net interest margin, for the three and nine month
periods ended September 30, 1994 and 1993.  Average balances for securities in
the "available for sale" category are calculated using amortized cost.
Nonperforming loans are included in average loans.  Interest on loans includes
loan fees.  The tax-equivalent calculation for tax-exempt income on securities
and loans assumes a 34% federal tax rate, and is adjusted for any interest
expense deduction that would be disallowed, according to current tax law.

ANALYSIS OF INCOME STATEMENT ITEMS

Third quarter net interest income increased by 13% over the prior year, to $6.1
million.  Nine month net interest income increased by nearly 9%, to $17.2
million in 1994.  As discussed previously, this was mostly due to larger
average balances of earning assets, and only modest increases in interest
expense.  See the preceding analysis of changes in FTE net interest income for
more details.

The quarterly provision for loan losses decreased by $75,000 from 1993's third
quarter.  This brought net interest income after the provision to $5.9 million
for the quarter, an increase of more than 15% over the third quarter of 1993.
For the nine months, the loan loss provision dropped by 26%, or $175,000.
Year-to-date net interest income after the provision increased by 10%, to $16.7
million.  The provision for both time frames was lowered due to the health of
the local economy, as evidenced by lower average levels of nonperforming loans.

Year-to-date noninterest income increased by $279,000 over the previous year,
primarily due to a $269,000 gain on the sale of a parcel of land.

Third quarter noninterest expense rose by 12%, to $5.0 million in 1994.
Noninterest expense for the nine month period rose more modestly, by $908,000,
or 7%.  The increases are attributable to increased salaries and benefits,
common in a service-intensive industry, and also to increased write-offs on a
foreclosed property.  We also noted increased advertising expenses due to
several new ad campaigns.

For the quarter, income before taxes increased by nearly 16% over 1993's third
quarter.  Net income was a record $1.5 million, a 15% increase over the
previous year.  For the nine months ended September 30, 1994, income before
taxes and the cumulative effect of an accounting change increased by almost
22%, or $0.9 million, to $5.2 million.  In early 1993, a one-time charge of
$1.2 million had been recorded for postretirement benefits, due to the
implementation of SFAS No. 106, "Employer's Accounting for Postretirement
Benefits Other Than Pensions." Income tax expense was $1.2 million for the nine
months ended September 30, 1994, compared with $0.9 million in 1993.  These
combined for a $1.8 million increase in year-to-date net income, to a record
$4.0 million.


LIQUIDITY AND ASSET/LIABILITY MANAGEMENT

The liquidity of a bank allows it to provide funds to meet loan requests, to
accommodate possible outflows in deposits, and to take advantage of other
investment opportunities.  Funding of loan requests, providing for liability
outflows, and managing interest rate margins require continuous analysis to
match the maturities of specific categories of loans and investments with
specific types of deposits and borrowings.  Bank liquidity is thus normally
defined by the mix of the banking institution's potential sources and uses of
funds.  For the Corporation, the major sources of liquidity have been federal
funds sold, and loans (including demand loans) and securities maturing within
one year.  At September 30, 1994 and 1993, federal funds sold amounted to $21.5
million and $9.8 million, respectively.  Loans (including demand loans) and
securities maturing within one year amounted to $105.2 million at September 30,
1994, and $111.0 million at September 30, 1993.  Additional liquidity is
provided by two repurchase agreement lines of credit with other banks, totaling
$15.0 million, and a $25.0 million line of credit with the Federal Home Loan
Bank (FHLB).  These lines could be drawn upon for short term liquidity needs,
if necessary.  The FHLB line of credit would be collateralized with securities,
if drawn upon.  The Corporation has also identified certain securities as
"available for sale," which may be sold for liquidity or other purposes.
Management determines the adequacy of items so classified by considering normal
deposit fluctuations, expected loan demand, and the other liquidity sources and
needs discussed above.  The Corporation's dependence on large deposits that
experience volatile rate changes is closely monitored.  These deposits consist
mainly of time certificates of deposit of $100,000 and over, of which the
balance was $67.9 million and $75.2 million at September 30, 1994 and 1993,
respectively.

Managing rates on earning assets and interest bearing liabilities focuses on
maintaining stability in the net interest spread, an important factor in
earnings growth and stability.  Emphasis is placed on maintaining a controlled
rate sensitivity position, to avoid wide swings in spreads and to minimize risk
due to changes in general interest rates.

The following table shows the rate sensitivity of the Corporation's interest
earning assets and interest bearing liabilities as of September 30, 1994.  This
table displays the interest rate sensitivity gap (i.e., interest rate sensitive
assets less interest rate sensitive liabilities), cumulative interest rate
sensitivity gap, the interest rate sensitivity gap ratio (i.e., interest rate
sensitive assets divided by interest rate sensitive liabilities), and
cumulative interest rate sensitivity gap ratio.  For the purposes of this
table, an asset or liability is considered rate sensitive within a specified
period when it matures or could be repriced within such period, generally
according to its contractual terms.

             due to the Corporation's experience that the interest rates on
             (and balances of) these accounts are relatively insensitive to
             interest rate changes.

The preceding table indicates the time periods in which interest earning assets
and interest bearing liabilities will mature or may be repriced, generally
according to their contractual terms.  However, this table does not necessarily
indicate the impact that general interest rate movements would have on the
Corporation's net interest yield, because the repricing of various categories
of assets and liabilities is discretionary and is subject to competitive and
other pressures.  As a result, various assets and liabilities indicated as
repricing within the same period may, in fact, reprice at different times and
by different increments.

At September 30, 1994, the Corporation is considered "asset sensitive"
according to the preceding table.  In a rising rate environment, the
Corporation might be able to increase rates on earning assets faster than the
increase in rates on interest bearing liabilities.

The Corporation also uses a computer model to simulate the effects of possible
interest rate changes.  As a guideline, estimated negative exposure to changing
rates within the ensuing year is limited to 5% of net interest income.  The
exposure estimate is based on a variety of assumptions built into the model,
and assumed interest rate changes of plus or minus 200 basis points.  The
results of this analysis are reported to the Asset/Liability and Funds
Management Committee, to assist in the interest rate risk management process.

In each accounting period, the allowance for loan losses is adjusted by
management, taking a variety of factors into account.  Through its internal
loan review department, management has attempted to allocate specific portions
of the allowance for loan losses based on specifically identifiable problem
loans.  Management's evaluation of the allowance is further based on
consideration of actual loss experience, the present and prospective financial
condition of borrowers, adequacy of collateral, industry concentrations within
the portfolio, and general economic conditions.  Management believes that the
present allowance is adequate, based on the broad range of considerations
listed above.

The primary risk element considered by management regarding each installment
and residential real estate loan is lack of timely payment.  Management has a
reporting system that monitors past due loans and has adopted policies to
pursue its creditor's rights in order to preserve the Bank's position.  The
primary risk elements concerning commercial loans are the financial condition
of the borrower, the sufficiency of collateral, and lack of timely payment.
Management has a policy of requesting and reviewing annual financial statements
from its commercial loan customers and periodically reviews existence of
collateral and its value.

Although management believes that the allowance for loan losses is adequate to
absorb losses as they arise, there can be no assurance that the Bank will not
sustain losses in any given period that could be substantial in relation to the
size of  the allowance for loan losses.

Management is not aware of any factors that would cause future net loan
charge-offs, in total or by loan category, to significantly differ from those
experienced in the past.

                          AGREEMENT AND PLAN OF MERGER


        This Agreement and Plan of Merger (the "PLAN OF MERGER") is made as of
August 24, 1994, between FIRST NATIONAL BANK CORP., a Delaware corporation
("FNBC"), and OLD KENT FINANCIAL CORPORATION, a Michigan corporation ("OLD
KENT"), One Vandenberg Center, Grand Rapids, Michigan.

        Old Kent and FNBC desire that FNBC become affiliated with Old Kent. 
The affiliation would be effected through the merger of FNBC with and into Old
Kent in accordance with this Plan of Merger and in accordance with the General
Corporation Law of the State of Delaware, as amended (the "DELAWARE LAW") and
the Business Corporation Act of the State of Michigan, as amended (the
"MICHIGAN ACT").  The transactions contemplated by and described in this Plan
of Merger are referred to as the "MERGER."

        Old Kent is a bank holding company registered as such with the Board of
Governors of the Federal Reserve System (the "FEDERAL RESERVE BOARD") under the
Bank Holding Company Act of 1956, as amended (the "FEDERAL BANK HOLDING COMPANY
ACT").  Old Kent has authorized capital stock consisting of 175,000,000 shares,
divided into two classes: 150,000,000 shares of common stock, $1 par value
("OLD KENT COMMON STOCK"); and 25,000,000 shares of preferred stock, without
par value, of which 3,000,000 shares are designated Series A Preferred Stock
and 300,000 shares are designated Series B Preferred Stock.  Each share of Old
Kent Common Stock is entitled to one vote on all matters submitted for a vote
of the shareholders.  As of August 19, 1994, there were 40,684,878 shares of
Old Kent Common Stock issued and outstanding, and 2,609,700 shares of Old Kent
Common Stock were reserved for issuance in connection with employee stock
option and benefit plans.  As of the date of this Plan of Merger, no shares of
preferred stock were issued and outstanding.  The number of issued and
outstanding shares of Old Kent Common Stock is subject to change before the
Effective Time of the Merger (as defined in Section 1.3 (Effective Time of the
Merger)) by reason of the issuance of additional shares of Old Kent Common
Stock upon the exercise of employee stock options and the grant or sale of
shares to, or for the account of, employees and directors pursuant to other
benefit plans, and the issuance of additional shares if and as authorized by
Old Kent's Board of Directors.

        FNBC is a bank holding company registered as such with the Federal
Reserve Board under the Federal Bank Holding Company Act.  FNBC has authorized
capital stock consisting of 10,000,000 shares, divided into two classes: 
8,000,000 shares of common stock, $3.125 par value ("FNBC COMMON STOCK"); and
2,000,000 shares of preferred stock, $.01 par value.  Each share of FNBC Common
Stock is entitled to one vote on all matters submitted for a vote of the
stockholders. As of the date of this Plan of Merger, there were 2,434,060
shares of FNBC Common Stock issued and outstanding, and 220,204 shares of FNBC
Common Stock were reserved for issuance in connection with director and
employee stock option plans.  As of the date of this Plan of Merger, no shares
of preferred stock were

issued and outstanding.  The number of issued and outstanding shares of FNBC
Common Stock is subject to change before the Effective Time of the Merger (as
defined in Section 1.3 (Effective Time of the Merger)) by reason of the
issuance of additional shares of FNBC Common Stock upon the exercise of
director and employee stock options.

        The respective Boards of Directors of FNBC and Old Kent each deem the
Merger advisable and in the best interests of its corporation and its
respective stockholders and shareholders.  FNBC and Old Kent have each
approved, adopted, and authorized the execution, delivery, and performance of
this Plan of Merger by resolutions duly adopted by their respective Boards of
Directors or duly authorized committees thereof.  The Board of Directors of
FNBC has directed that this Plan of Merger be submitted to FNBC's stockholders
for adoption and approval.

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

all statutory waiting periods; and (ii) the requisite approval of this Plan of
Merger by the stockholders of FNBC.  Scheduling or commencing the Closing shall
not, however, constitute a waiver of the conditions precedent of either Old
Kent or FNBC as set forth in Articles VII and VIII, respectively.  Upon
completion of the Closing, FNBC and Old Kent shall execute and deliver
appropriate certificates of merger in the forms and as required by the Delaware
Law and the Michigan Act (the "CERTIFICATES OF MERGER").

        1.3   Effective Time of the Merger.  Subject to the terms and
conditions of this Plan of Merger, the Merger shall be consummated as promptly
as possible following the Closing by filing the Certificates of Merger in the
manner required by law.  The "EFFECTIVE TIME OF THE MERGER" shall be the close
of business on a date to be specified in the Certificates of Merger, which
shall be as soon as practicable, but not later than 3 business days, after the
Closing.

        1.4   Merger of FNBC with and into Old Kent.  FNBC shall be merged with
and into Old Kent (each sometimes being referred to as a "CONSTITUENT
CORPORATION" prior to the Merger) upon the filing of the Certificates of Merger
with the administrators authorized by law to administer the Delaware Law and
the Michigan Act.  At the Effective Time of the Merger, the Constituent
Corporations shall become a single corporation, which shall be Old Kent (the
"SURVIVING CORPORATION").  The Surviving Corporation shall have all of the
rights, privileges, immunities, and powers, and shall be subject to all of the
duties and liabilities, of a corporation organized under the Michigan Act.

        1.5   Effect of the Merger.  From and after the Effective Time of the
Merger, 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 as provided in Subchapter Nine of the Delaware Law with respect to the
merger of a domestic and a foreign corporation where the surviving corporation
will be subject to the laws of the State of Michigan.

        1.6   Additional Actions.  If, at any time after the Effective Time of
the Merger, the Surviving Corporation shall determine that any 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 FNBC 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, then FNBC shall be deemed to have granted to
the Surviving Corporation an irrevocable power of attorney to execute and
deliver all such proper deeds, assignments, and assurances in law and to do all
acts necessary or proper to vest, perfect, or confirm title to and possession
of such rights, properties, or assets in the Surviving Corporation and to
otherwise carry out the purposes of this Plan of Merger.  The proper officers
and directors of the Surviving Corporation are fully authorized in the name of
FNBC to take any and all such action as may be contemplated by this Article.

                                   ARTICLE II

                       CONVERSION AND EXCHANGE OF SHARES

        2.1   Conversion of Shares.  At the Effective Time of the Merger, by
virtue of the Merger:

                2.1.1  Conversion of FNBC Common Stock.  Subject to the
        provisions of Sections 2.2 (Upset Provisions), 2.3 (No Fractional
        Securities), 2.4 (Adjustments), and 5.5 (Data Processing Arrangements)
        hereof, each share of FNBC Common Stock outstanding immediately prior
        to the Effective Time of the Merger shall be converted into that number
        (the "EXCHANGE RATE") of validly issued, fully paid, and nonassessable
        shares of Old Kent Common Stock, rounded to the nearest ten thousandth
        of a share, determined by dividing $35.00 (the "PURCHASE PRICE PER
        SHARE") by the average of the per share closing prices of Old Kent
        Common Stock reported on the NASDAQ National Market System during the
        20 consecutive trading days ending on the sixth business day prior to
        the date of the Closing (the "REFERENCE PERIOD") as reported in the Dow
        Jones News/Retrieval system, or other equally reliable means (as so
        calculated, the "FINAL STOCK PRICE"); provided that:





                                      -4-

<PAGE>   12
                        (a)  if the Final Stock Price shall be greater than
                $36.00 (the "CEILING PRICE"), then the Exchange Rate shall be
                determined by dividing the Purchase Price Per Share by the
                Ceiling Price; and

                        (b)  if the Final Stock Price shall be less than $32.00
                (the "FIRST FLOOR PRICE"), then the Exchange Rate shall be
                determined by dividing the Purchase Price Per Share by the
                First Floor Price.

                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 Series B
        Preferred Stock Purchase Rights ("OLD KENT RIGHTS") issued pursuant to
        a Rights Agreement dated as of December 19, 1988 between Old Kent and
        Old Kent Bank and Trust Company (the "OLD KENT RIGHTS AGREEMENT") then
        represented by each share of Old Kent Common Stock at the Effective
        Time of the Merger, as long as the Old Kent Rights are not then
        separately transferable.  As of the date of this Plan of Merger, each
        share of Old Kent Common Stock represents two-thirds (2/3rds) of an Old
        Kent Right.  The number of Old Kent Rights represented by each share of
        Old Kent Common Stock is subject to adjustment upon the occurrence of
        certain events set forth in the Old Kent Rights Agreement.

                2.1.3  Conversion of Old Kent Common Stock.  Each share of Old
        Kent Common Stock outstanding immediately prior to the Effective Time
        of the Merger shall continue to be outstanding without any change. 
        Each shareholder of the Surviving Corporation whose shares were
        outstanding immediately before the Effective Time of the Merger will
        hold the same number of shares, with identical designations,
        preferences, limitations, and relative rights, immediately after the
        Effective Time of the Merger.

                2.1.4  Treasury Stock and Stock Held by Old Kent.  Each share
        of FNBC Common Stock held by FNBC 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.  Each share of FNBC
        Common Stock, if any, held by Old Kent or any of Old Kent's
        subsidiaries for its own account and not in a fiduciary capacity for a
        person other than Old Kent or any of Old Kent's subsidiaries shall be
        canceled and no consideration shall be issuable or payable with respect
        to any such share.

                2.1.5  FNBC Common Stock No Longer Outstanding.  Each share of
        FNBC Common Stock outstanding immediately prior to the Effective Time
        of the Merger shall be deemed to be no longer outstanding and to
        represent solely the right to receive shares of Old Kent Common Stock
        as provided in Section 2.1.1 (Conversion of FNBC Common Stock) (the
        "MERGER CONSIDERATION"), together with any dividends and other
        distributions payable as provided in Section 2.6.4 (Dividends Pending





                                      -5-

<PAGE>   13

        Surrender), but subject to the payment of cash in lieu of fractional 
        shares as provided in Section 2.3 (No Fractional Securities).

        2.2   Upset Provisions.

                2.2.1  Upset Condition.  The "UPSET CONDITION" shall exist if,
        after the Closing is properly called pursuant to Section 1.2 (The
        Closing), both of the following conditions exist:

                        (a)  The Final Stock Price is less than $28.90 (the
                "SECOND FLOOR PRICE"), subject to adjustment under Section 2.4
                (Adjustments); and

                        (b)  The percentage determined by dividing the Final
                Stock Price by $34.00 (the "FIXING PRICE") is more than 15
                percentage points less than the percentage determined by
                dividing the Aggregate Price Per Share of the Comparison Stocks
                on the last day of the Reference Period by the Aggregate Price
                Per Share of the Comparison Stocks on August 19, 1994 (the
                "COMPARISON STOCKS BASE PRICE PER SHARE"), subject to
                adjustment under Section 2.4 (Adjustments).

        The "AGGREGATE PRICE PER SHARE OF THE COMPARISON STOCKS" means the sum
        of the closing prices of all of the Comparison Stocks as reported in 
        the Dow Jones News/Retrieval system, or other equally reliable means,
        for each day in question.  The "COMPARISON STOCKS" mean the most 
        widely held class of common stock of each of the following
        corporations (the closing price and trading symbol of each stock on
        August 19, 1994, are listed below for reference purposes only):

         provided, however, that any of these corporations shall be excluded    
         from this definition and from the comparison described in Section
         2.2.1(b) if between August 19, 1994, and the end of the Reference 
         Period there is publicly announced a proposed merger, acquisition, or
         business combination of that corporation, or a tender offer or exchange
         offer for, or other transaction involving the acquisition of a majority
         of, that corporation's common stock or assets.

                 2.2.2    FNBC's Rights in Upset Condition.  If the Upset
         Condition shall then exist, FNBC shall have the right, exercisable at
         any time prior to 5 p.m. Grand Rapids, Michigan time on the second
         business day after the last day of the Reference Period (the "EXERCISE
         PERIOD"), to either (i) abandon the Merger and terminate this Plan of
         Merger (by delivering to Old Kent within the Exercise Period written
         notice of its decision to do so) and, upon the delivery of such notice
         by FNBC, the Merger shall be abandoned and this Plan of Merger shall
         immediately terminate; (ii) proceed with the Merger on the basis of
         the Exchange Rate determined pursuant to Section 2.1.1 (Conversion of
         FNBC Common Stock) (by delivering to Old Kent within the Exercise
         Period written notice of its decision to do so or by failing to
         deliver any notice to Old Kent pursuant to this Section 2.2.2 (FNBC's
         Rights in Upset Condition) during the Exercise Period); or (iii)
         request Old Kent to increase the Exchange Rate (by delivering to Old
         Kent within the Exercise Period written notice to such effect (an
         "INCREASE NOTICE")) for each share of FNBC Common Stock to that number
         of shares of Old Kent Common Stock determined by dividing the Purchase
         Price Per Share by the Second Floor Price (the "ADJUSTED RATE").

                 2.2.3    Old Kent's Rights in Upset Condition.  If the Upset
         Condition occurs and Old Kent receives an Increase Notice pursuant to
         Section 2.2.2 (FNBC's Rights in Upset Condition), Old Kent shall
         either accept or decline the Adjusted Rate by delivering written
         notice of its decision to FNBC at or before 5 p.m. Grand Rapids,
         Michigan time on the third business day after the expiration of the
         Exercise Period (the "ACCEPTANCE PERIOD").  If Old Kent accepts the
         Adjusted Rate within the Acceptance Period, this Plan of Merger shall
         remain in effect in accordance with its terms except that the Exchange
         Rate shall be equal to the Adjusted Rate.  If Old Kent





                                      -7-

<PAGE>   15
         declines the Adjusted Rate within the Acceptance Period or fails to
         deliver written notice of its decision to accept or decline the
         Adjusted Rate within the Acceptance Period, the Merger shall be
         abandoned and this Agreement shall thereupon terminate without further
         action by FNBC or Old Kent effective as of 5 p.m. Grand Rapids,
         Michigan time on the second business day following the expiration of
         the Acceptance Period; provided, however, that if Old Kent so declines
         the Adjusted Rate or so fails to deliver written notice of its
         decision to accept or decline the Adjusted Rate within the Acceptance
         Period, FNBC may, by written notice delivered to Old Kent at or before
         5 p.m. Grand Rapids, Michigan time on the second business day
         following the expiration of the Acceptance Period, elect to proceed
         with the Merger and the transactions contemplated by this Plan of
         Merger on the basis of the Exchange Rate determined pursuant to
         Section 2.1.1(Conversion of FNBC Common Stock) and, upon such
         election, no abandonment of the Merger or termination of this Plan of
         Merger shall be deemed to have occurred, this Plan of Merger shall
         remain in effect in accordance with its terms and the Closing shall
         thereafter occur in accordance with the terms of this Plan of Merger.

         2.3   No Fractional Securities.  Notwithstanding any other provision
of this Agreement, no certificates or scrip representing fractional shares of
Old Kent Common Stock shall be issued upon the surrender for exchange of
certificates which represented shares of FNBC Common Stock outstanding
immediately prior to the Effective Time of the Merger ("OLD CERTIFICATES")
(taking into account all Old Certificates surrendered for exchange by a
particular FNBC stockholder) pursuant to Section 2.6 (Surrender of Old
Certificates and Distribution of Old Kent Common Stock) and no Old Kent
dividend or other distribution or stock split shall relate to any fractional
shares of Old Kent Common Stock, and such fractional interests shall not
entitle the owner thereof to vote or to any rights of a shareholder of Old
Kent.  In lieu of any such fractional shares, each holder of an Old Certificate
who would otherwise have been entitled to a fraction of a share of Old Kent
Common Stock upon surrender of such Old Certificate for exchange pursuant to
Section 2.6 (Surrender of Old Certificates and Distribution of Old Kent Common
Stock) will be paid an amount in cash (without interest) equal to such fraction
of a share multiplied by the Final Stock Price.

         2.4   Adjustments.  The Exchange Rate and related amounts and related
computations described in Sections 2.1 (Conversion of Shares) and 2.2 (Upset
Provisions) shall be adjusted in the manner provided in this Section 2.4
(Adjustments) upon the occurrence of any of the following events:

                 2.4.1    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 and the
         ex-dividend or ex-distribution date for such stock dividend, stock
         split, or distribution occurs prior to the beginning of the Reference
         Period, then the Fixing Price, Ceiling Price, First Floor Price, and
         Second Floor Price shall be adjusted by multiplying them by that ratio
         (i) the numerator of which





                                      -8-

<PAGE>   16
         shall be the total number of shares of Old Kent Common Stock
         outstanding 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 outstanding immediately
         after such dividend, split, or distribution.

                 2.4.2    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 which would substantially change the
         number and value of outstanding shares of Old Kent Common Stock; a
         distribution of warrants or rights with respect to Old Kent Common
         Stock; or any other transaction which would have a substantially
         similar effect; then the nature or amount of the consideration to be
         received by the stockholders of FNBC in exchange for their shares of
         FNBC Common Stock and the Exchange Rate 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 surviving corporation and which merger does not result
         in any reclassification of Old Kent Common Stock, holders of FNBC
         Common Stock would receive, in lieu of each share of Old Kent Common
         Stock to be issued in exchange for FNBC Common Stock, the kind and
         amount of shares of Old Kent stock, other securities, money, and/or
         property receivable upon such reclassification, consolidation, 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.

                 2.4.3    Postponement of Closing.  Old Kent and FNBC agree not
         to convene the Closing at any time which would result in there being an
         ex-dividend or ex-distribution date for any transaction described in
         Subsections 2.4.1 or 2.4.2 at any time after the beginning of the
         Reference Period.

                 2.4.4    Employee Stock Options, Etc.  Notwithstanding the
         foregoing subsections of this Section 2.4 (Adjustments), 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 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 so long as such grants or sales of
         shares are substantially consistent with Old Kent's past practice or
         not materially dilutive to Old Kent's shareholders.

                 2.4.5    Authorized but Unissued Shares.  Notwithstanding the
         other provisions of this Section 2.4 (Adjustments), no adjustment
         shall be made in the event of the issuance of additional shares of Old
         Kent Common Stock or other securities pursuant





                                      -9-

<PAGE>   17
         to a public offering, private placement, or an acquisition of one or
         more banks, corporations, or business assets for consideration which
         the Board of Directors of Old Kent, or a duly authorized committee
         thereof, determines to be fair and reasonable.

                 2.4.6    Changes in Capital.  Subject only to making any
         adjustment to the Purchase Price Per Share and related computations
         prescribed by this Section 2.4 (Adjustments), nothing contained in
         this Plan of Merger is intended to preclude Old Kent from amending its
         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 which are convertible
         into shares of capital stock.

                 2.4.7    Increase in Outstanding Shares of FNBC Common Stock.
         In the event that the number of shares of FNBC Common Stock
         outstanding is greater than 2,434,060 for any reason whatsoever
         (whether or not such increase constitutes a breach of this Plan of
         Merger), other than the issuance of not more than 220,204 shares upon
         the exercise of FNBC stock options identified in Section 4.4.2 (No
         Other Capital Stock), then the Purchase Price Per Share shall be
         adjusted to that price determined by multiplying the Purchase Price
         Per Share by a fraction (i) the numerator of which shall be 2,434,060
         (the total number of shares of FNBC 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 FNBC Common Stock outstanding as of
         the Effective Time of the Merger, excluding not more than 220,204
         shares, if any, issued after the date of this Plan of Merger upon the
         exercise of FNBC stock options identified in Section 4.4.2 (No Other
         Capital Stock).

         2.5   Cessation of Shareholder Status.  As of the Effective Time of
the Merger, record holders of Old Certificates shall cease to be stockholders
of FNBC and shall have no rights as FNBC stockholders.  Such Old Certificates
shall then represent the right to receive 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.

         2.6   Surrender of Old Certificates and Distribution of Old Kent
Common Stock.  After the Effective Time of the Merger, 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:

                 2.6.1  Transmittal Materials.  As soon as practicable after
         the Effective Time of the Merger, Old Kent shall send or cause to be
         sent to each record holder of FNBC Common Stock as of the Effective
         Time of the Merger transmittal materials for use in exchanging that
         holder's Old Certificates for Old Kent Common Stock certificates.  The
         transmittal materials will contain instructions with respect to the
         surrender of Old Certificates.

<PAGE>   18
                 2.6.2  Exchange Agent.  As soon as practicable after the
         Effective Time of the Merger, Old Kent will deliver to Old Kent Bank
         and Trust Company, or such other bank or trust company as Old Kent may
         designate (the "EXCHANGE AGENT"), the number of shares of Old Kent
         Common Stock issuable and the amount of cash payable for fractional
         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.

                 2.6.3  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 FNBC's stock records as of
         the Effective Time of the Merger, or in such other name or to such
         other address as may be specified by the holder of record in
         transmittal documents received by the Exchange Agent; provided, that:

                          (a)  Receipt of Old Certificates.  With respect to
                 each FNBC 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

                          (b)  Satisfactory Form.  Such certificates,
                 transmittal materials, affidavits, and bonds are in a form and
                 condition reasonably acceptable to Old Kent and the Exchange
                 Agent.

                 2.6.4  Dividends Pending Surrender.  Whenever a dividend is
         declared by Old Kent on Old Kent Common Stock which is payable to
         shareholders of record of Old Kent as of a record date on or after the
         Effective Time of the Merger, the declaration shall include dividends
         on all shares issuable under this Plan of Merger.  No former
         stockholder of FNBC 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, which may have been imposed or
         paid thereon) declared and paid with respect to the shares of Old Kent
         Common Stock represented thereby.

                 2.6.5  Stock Transfers.  On or after the Effective Time of the
         Merger, there shall be no transfers on the stock transfer books of
         FNBC of the shares of FNBC Common Stock which were issued and
         outstanding immediately prior to the Effective Time of the Merger.
         If, after the Effective Time of the Merger, Old Certificates are
         properly presented for transfer, then they shall be canceled and
         exchanged for stock certificates representing shares of Old Kent
         Common Stock as provided in this Plan of





                                      -11-

<PAGE>   19
         Merger.  After the Effective Time of the Merger, ownership of such
         shares as are represented by any Old Certificates may be transferred
         only on the stock transfer records of Old Kent.

                 2.6.6  Exchange Agent's Discretion.  The Exchange Agent shall
         have discretion to determine reasonable rules and procedures relating
         to the issuance and delivery of certificates of Old Kent Common Stock
         into which shares of FNBC Common Stock are converted in the Merger and
         governing the payment for fractional shares of FNBC Common Stock.

1993, as reported on by Old Kent's independent accountants, Arthur Andersen &
Co., and the unaudited consolidated financial statements of Old Kent and Old
Kent's subsidiaries as of and for the quarter ended June 30, 1994, including
all schedules and notes relating to such statements, as previously delivered to

accounting principles applied consistently throughout the periods indicated
(except as otherwise noted in such financial statements or the notes thereto).

Kent and Old Kent's subsidiaries on a consolidated basis for reasons specific
to Old Kent and not applicable to the banking industry in general.

         3.7   Absence of Litigation.  There is no action, suit, proceeding,
claim, arbitration, or investigation pending or threatened by any person,

of its subsidiaries, any of which has or may have a material adverse effect on
the business, income, or financial condition of Old Kent and its subsidiaries
on a consolidated basis.  There is no factual basis known to Old Kent which
presents a reasonable potential for any such action, suit, proceeding, claim,
arbitration, or investigation.

conducted their respective businesses and used their respective properties
substantially in 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,

defined in Section 4.21.2 Environmental Laws)); except for violations which
would not have a material adverse effect on the business, income, or financial
condition of Old Kent and its subsidiaries on a consolidated basis.

default by Old Kent, any of Old Kent's subsidiaries, or any other party, under
any contract or agreement to which Old Kent or any of its subsidiaries is a
party, or by which they are bound, which would have a material adverse effect
on the business, income, or financial condition of Old Kent and its
subsidiaries on a consolidated basis.

benefit plan," any "employee pension benefit plan," or any "employee benefit

Old Kent and each Employee Benefit Plan is in substantial compliance with

         3.11  Environmental Matters.  Old Kent and its subsidiaries have
complied with all Environmental Laws (as defined in Section 4.21.2

         4.11  Absence of Defaults Under Contracts.  There is no existing
default by FNBC or any of FNBC's Subsidiaries, or any other party, under any
contract or agreement to which FNBC or any of FNBC's Subsidiaries is a party,
or by which they are bound, which could have a material adverse effect on the
business, income, or financial condition of FNBC or any of FNBC's Subsidiaries.

         4.12  SEC and Other Filings.  In the last five years:

                 4.12.1  SEC Filings.  FNBC has filed, and 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;

                 4.12.2  Regulatory Filings.  FNBC has filed in a timely manner
         all other filings with other regulatory bodies for which filings are
         required;

                 4.12.3  Complete and Accurate.  All such filings, as amended,
         were complete and accurate in all material respects as of the dates of
         such filings, and there were no misstatements or omissions therein
         which, as of the making of this representation and warranty, would be
         material to the business, income, or financial condition of FNBC and
         FNBC's Subsidiaries on a consolidated basis; and

                 4.12.4  Compliance with Regulations.  All such filings
         complied in all material respects with all regulations, forms, and
         guidelines applicable to such filings.

         4.13  Registration Statement, Etc.

                 4.13.1  Accurate Information.  None of the information to be

                                      -24-

<PAGE>   32
                          (a)  Be false or misleading with respect to any
                 material fact, or omit to state any material fact necessary to
                 make the statements therein not misleading (i) at the
                 respective times such Documents are filed; (ii) with respect
                 to the Registration Statement, when it becomes effective; and
                 (iii) with respect to the Prospectus and Proxy Statement, when
                 it is mailed.

                          (b)  With respect to the Registration Statement and
                 the Prospectus and Proxy Statement, as either may be amended
                 or supplemented, at the time of the Stockholders' Meeting, be
                 false or misleading with respect to any material fact, or omit
                 to state any material fact necessary to correct any statement
                 in any earlier communication with respect to the solicitation
                 of any proxy for the Stockholders' Meeting.

                 4.13.2  Compliance of Filings.  All documents which FNBC is
         responsible for filing with the SEC and any regulatory agency in
         connection with the Merger will comply as to form in all material
         respects with the provisions of applicable law.

         4.14  Tax Matters.

                 4.14.1  Tax Returns.  FNBC and FNBC's Subsidiaries have duly
         and timely filed all material tax returns which they have by law been
         required to file, including without limitation those with respect to
         income, withholding, social security, unemployment, franchise, real
         property, personal property, 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 regulations.

                 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 FNBC and
         FNBC's Subsidiaries have been paid in full as and when due.  The
         provisions made for taxes on the consolidated balance sheet of FNBC
         and FNBC's Subsidiaries as of December 31, 1993, are sufficient for
         the payment of all federal, state, county, and local taxes of FNBC and
         FNBC's Subsidiaries accrued but unpaid as of the date indicated,
         whether or not disputed, with respect to all periods through December
         31, 1993.

                 4.14.3  Tax Audits.  None of the federal consolidated income
         tax returns of FNBC and FNBC's Subsidiaries filed for any tax year
         after 1988 have been audited by the Internal Revenue Service (the
         "IRS").  There is no tax audit or legal or administrative proceeding
         for assessment or collection of taxes pending or, to FNBC's knowledge,
         threatened with respect to FNBC or any of FNBC's Subsidiaries.  No
         claim for assessment or collection of taxes has been asserted with
         respect to FNBC or





                                      -25-

<PAGE>   33
         any of FNBC's Subsidiaries.  No waiver of any limitations statute or
         extension of any assessment or collection period has been executed by
         or on behalf of FNBC or any of FNBC's Subsidiaries.

         4.15  Title to Properties.  FNBC and FNBC's Subsidiaries have good,
sufficient, 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 the consolidated balance sheet of
FNBC and FNBC's Subsidiaries as of December 31, 1993, 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 the
         consolidated balance sheet of FNBC and FNBC's Subsidiaries as of
         December 31, 1993, and the notes thereto;

                 4.15.2  Normal to Business.  Liens for current taxes not yet
         delinquent, and liens or encumbrances which are normal to the business
         of FNBC and FNBC's Subsidiaries and which are not material in relation
         to the business, income, or financial condition of FNBC or any of
         FNBC's Subsidiaries; and

                 4.15.3  Immaterial Imperfections.  Such imperfections of
         title, easements, 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 properties
         subject thereto or affected thereby, or which would not otherwise be
         material to the business, income, or financial condition of FNBC or
         any of FNBC's Subsidiaries.

         4.16  Condition of Real Property.  No building or improvement on any
real property owned, leased, or used by FNBC or any of FNBC's Subsidiaries
encroaches on any easement or property owned by another, and no building or
property owned by another encroaches on any real property owned, leased, or
used by FNBC or any of FNBC's Subsidiaries or on any easement the benefit of
which runs to real property owned, leased, or used by FNBC or any of FNBC's
Subsidiaries.  None of the boundaries of any parcel of real property owned,
leased, or used by FNBC or any of FNBC's Subsidiaries deviates substantially
from those shown on the survey of such parcel, if any, attached to the FNBC
Disclosure Statement or from what they appear to be through visual inspection.
Neither FNBC nor any of FNBC's Subsidiaries is in material violation of any
zoning regulation, building restriction, restrictive covenant, ordinance, or
other law, order, regulation, or requirement relating to any real property that
FNBC or any of FNBC's Subsidiaries owns, leases, or uses and that is material
to the conduct of the business of FNBC and FNBC's Subsidiaries.  All buildings
and improvements that FNBC or any of FNBC's Subsidiaries owns, leases, or uses
and that are material to the conduct of the business of FNBC and FNBC's
Subsidiaries are in good condition (normal wear and tear excepted), are
structurally sound and not in need of material





                                      -26-

<PAGE>   34
repairs, are fit for their intended purposes, and are adequately serviced by
all utilities necessary for the effective operation of FNBC's and FNBC's
Subsidiaries' business as presently conducted.  None of the real property
owned, leased, or used by FNBC or any of FNBC's Subsidiaries and that are
material to the conduct of the business of FNBC and FNBC's Subsidiaries is the
subject of any condemnation action and there is, to the best of FNBC's
knowledge, no proposal under consideration by any public or governmental
authority or entity to use any of such properties for some other purpose.

         4.17  Leases.  All leases pursuant to which FNBC or any of FNBC's
Subsidiaries, as lessee, lease real or personal property which is material to
the business of FNBC or any of FNBC's Subsidiaries are valid, effective, and
enforceable against the lessor in accordance with their respective terms.
There is no existing default under any such lease, or any event which with
notice or lapse of time, or both, would constitute a default with respect to
FNBC or any of FNBC's Subsidiaries or, to the best knowledge of FNBC, any other
party.  No such lease contains a prohibition against assignment by FNBC or any
of FNBC's Subsidiaries, by operation of law or otherwise, or any other
provision which would preclude the Surviving Corporation or any of its direct
or indirect subsidiaries from possessing and using the leased premises for the
same purposes and upon the same rental and other terms upon consummation of the
Merger as are applicable to the possession and use by FNBC or any of FNBC's
Subsidiaries as of the date of this Plan of Merger.

         4.18  Licenses, Permits, Etc.

                 4.18.1  All Licenses, Permits, Etc.  FNBC and FNBC's
         Subsidiaries hold all licenses, certificates, permits, franchises, and
         rights from all appropriate federal, state, and other public
         authorities necessary for the conduct of their businesses as presently
         conducted, the lack of which would have a material adverse effect on
         the business, income, or financial condition of FNBC or any of FNBC's
         Subsidiaries.

                 4.18.2  Regulatory Action.  Neither FNBC nor any of FNBC's
         Subsidiaries:

                          (a)  Has within the last 5 years been charged with,
                 or to the best of FNBC's knowledge is under governmental
                 investigation with respect to, any actual or alleged violation
                 of any statute, ordinance, rule, regulation, guideline, or
                 standard; or

                          (b)  Is the subject of any pending or, to FNBC's
                 knowledge, threatened proceeding by any regulatory authority
                 having jurisdiction over its business, properties, or
                 operations.

         4.19  Certain Employment Matters.

                 4.19.1  Employment Policies, Programs, and Procedures.  The
         policies, programs and practices of FNBC and FNBC's Subsidiaries
         relating to equal opportunity and affirmative action, wages, hours of
         work, and other terms and conditions of employment are in compliance
         in all material respects with applicable laws, orders, regulations,
         and ordinances governing employment and terms and conditions of
         employment.

                 4.19.2  Record of Payments.  There are no existing or
         outstanding obligations of FNBC or any of FNBC's Subsidiaries, whether
         arising by operation of law, civil or common, by contract, or by past
         custom, for Employment-Related Payments (as defined in Section 4.19.3
         (Employment-Related Payments)) to trusts or other funds or to any
         governmental agency or to any present or former director, officer,
         employee, or agent (or his or her heirs, survivors, legatees, or legal
         representatives) which have not been duly recorded on the books and
         records of FNBC or FNBC's Subsidiaries and paid when due or duly
         accrued as a liability, except for obligations to the two officers of
         the Bank under the First National Bank in Macomb County Supplemental
         Executive Retirement Plan.

                 4.19.3  "Employment-Related Payments."  For purposes of this
         Plan of Merger, "EMPLOYMENT-RELATED PAYMENTS" include any payment to
         be made with respect to any contract for employment, unemployment
         compensation benefits, profit sharing, pension or retirement benefits
         or social security benefits, or for fringe benefits, including
         vacation or holiday pay, bonuses and other forms of compensation, or
         for medical insurance or medical expenses, which are payable to
         present or former directors, officers, employees, or agents, or their
         survivors, heirs, legatees, or legal representatives.

                 4.19.4  Employment Claims.  There are no disputes, claims, or
         charges, pending or threatened alleging breach of any express or
         implied employment contract or commitment, or breach of any applicable
         law, order, regulation, public policy or ordinance relating to
         employment or terms and conditions of employment, and there is no
         basis for any valid claim or charge with regard to such matters.

                 4.19.5  Disclosure of Agreements.  There is no written or
         oral, express or implied:

                          (a)  Employment contract or agreement, or guarantee
                 of job security, made with or to any past or present employee
                 of FNBC or any of FNBC's Subsidiaries which is not terminable
                 by FNBC or FNBC's Subsidiaries upon 60 days' or less notice
                 without penalty or obligation;

                 purchases, deferred compensation, retirement payments,
                 retirement benefits of the type described in Statement of
                 Financial Accounting Standard No. 106, or profit sharing; or

                          (c)  Plan, agreement, arrangement, or understanding
                 with respect to payment of medical expenses, insurance (except
                 insurance continuation limited to that required under
                 provisions of the Consolidated Omnibus Budget Reconciliation
                 Act), or other benefits for any former employee or any spouse,
                 child, member of the same household,  estate, or survivor of
                 any employee.

         4.20  Employee Benefit Plans.  With respect to any Employee Benefit
Plan (as defined in Section 3.10 (Employee Benefit Plans)) maintained by or for
the benefit of FNBC or any of FNBC's Subsidiaries or to which FNBC or any of
FNBC's Subsidiaries have made payments or contributions on behalf of its
employees:

                 4.20.1  ERISA Compliance.  FNBC and each of FNBC's
         Subsidiaries, each Employee Benefit Plan, and all trusts created
         thereunder are in substantial compliance with ERISA, including
         Sections 601-608 concerning continuation of health care coverage, and
         all other applicable laws and regulations insofar as such laws and
         regulations apply to such plans and trusts.

                 4.20.2  Internal Revenue Code Compliance.  FNBC and each of
         FNBC's Subsidiaries, each Employee Benefit Plan which is intended to
         be a qualified plan under Section 401(a) of the Internal Revenue Code,
         and all trusts created thereunder are in substantial compliance with
         the applicable provisions of the Internal Revenue Code, including
         Section 4980B concerning continuation of health care coverage.

                 4.20.3  Prohibited Transactions.  No Employee Benefit Plan and
         no trust created thereunder has been involved, subsequent to June 30,
         1974, in any nonexempt "prohibited transaction" as defined in Section
         4975 of the Internal Revenue Code and in Sections 406, 407, and 408 of
         ERISA.

                 4.20.4  Plan Termination.  No Employee Benefit Plan which is a
         qualified plan under Section 401(a) of the Internal Revenue Code and
         no trust created thereunder has been terminated, partially terminated,
         curtailed, discontinued, or merged into another plan or trust after
         January 1, 1985, except in compliance with notice and disclosure to
         the Internal Revenue Service and the Pension Benefit Guaranty
         Corporation (the "PBGC"), where applicable, as required by the
         Internal Revenue Code and ERISA.  With respect to each such
         termination, all termination procedures have been completed and there
         are no pending or potential liabilities to the PBGC, to the plans, or
         to participants under such terminated plans.  Each such termination,
         partial termination, curtailment, discontinuance, or consolidation has
         been ac-





                                      -29-

<PAGE>   37
         companied by the issuance of a current favorable determination letter
         by the IRS and, where applicable, has been accompanied by plan
         termination proceedings with and through the PBGC.

                 4.20.5  Multiemployer Plan.  No Employee Benefit Plan is a
         "multiemployer plan" within the meaning of Section 3(37)(A) of ERISA.

                 4.20.6  Defined Benefit Plan.  No Employee Benefit Plan in
         effect as of December 31, 1993, is a "defined benefit plan" within the
         meaning of Section 3(35) of ERISA.

                 4.20.7  Payment of Contributions.  FNBC and each of FNBC's
         Subsidiaries has made when due all contributions required under any
         Employee Benefit Plan and under applicable laws and regulations.

                 4.20.8  Payment of Benefits.  There are no payments which have
         become due from any Employee Benefit Plan, the trusts created
         thereunder, or from FNBC or any of FNBC's Subsidiaries which have not
         been paid through normal administrative procedures to the plan
         participants or beneficiaries entitled thereto, except for claims for
         benefits for which administrative claims procedures under such plan
         have not been exhausted.

                 4.20.9  Accumulated Funding Deficiency.  No Employee Benefit
         Plan which is intended to be a qualified plan under Section 401(a) of
         the Internal Revenue Code and no trust created thereunder has
         incurred, subsequent to June 30, 1974, an "accumulated funding
         deficiency" as defined in Section 412(a) of the Internal Revenue Code
         and Section 302 of ERISA (whether or not waived).

                 4.20.10  Filing of Reports.  FNBC has filed or caused to be
         filed, and will continue to file or cause to be filed, in a timely
         manner all filings pertaining to each Employee Benefit Plan with the
         IRS, the United States Department of Labor, and the PBGC as prescribed
         by the Internal Revenue Code or ERISA, or regulations issued
         thereunder.  All such filings, as amended, were complete and accurate
         in all material respects as of the dates of such filings, and there
         were no misstatements or omissions in any such filing which, as of the
         making of this representation and warranty, would be material to the
         financial condition, net income, business, properties, operations, or
         prospects of FNBC or any of FNBC's Subsidiaries.

         4.21  Environmental Matters.

                 4.21.1  Hazardous Substances.  For purposes of this Plan of
         Merger, "HAZARDOUS SUBSTANCE" has the meaning set forth in Section
         9601 of the Comprehensive Environmental Response Compensation and
         Liability Act of 1980, as amended,





                                      -30-

<PAGE>   38
         42 U.S.C.A. Section  9601 et seq. ("CERCLA"), and also includes any
         substance now or in the future regulated by or subject to any
         Environmental Law (as defined below) and any other pollutant,
         contaminant, or waste, including, without limitation, petroleum,
         asbestos, radon, and polychlorinated biphenyls.

                 4.21.2  Environmental Laws.  For purposes of this Plan of
         Merger, "ENVIRONMENTAL LAWS" means all laws (civil or common),
         ordinances, rules, regulations, guidelines, and orders that: (i)
         regulate air, water, soil, or solid waste management, including the
         generation, release, containment, storage, handling, transportation,
         disposal, or management of Hazardous Substances; (ii) regulate or
         prescribe requirements for air, water, or soil quality; (iii) are
         intended to protect public health or the environment; or (iv)
         establish liability for the investigation, removal, or cleanup of, or
         damage caused by, any Hazardous Substance.

         Bank; and (iv) to FNBC's knowledge, any real estate formerly owned or
         leased by FNBC or any of FNBC's Subsidiaries (for purposes of this
         Section, properties described in any of (i) through (iv) are
         collectively referred to as "PREMISES"):

                          (a)  Construction and Content.  None of the Premises
                 is constructed of, or contains as a component part, any
                 material which (either in its present form or as it may
                 reasonably be expected to change through aging or normal use)
                 releases or may release any substance, whether gaseous,
                 liquid, or solid, that is a Hazardous Substance or is known to
                 be (either by single exposure or by repeated or prolonged
                 exposure) injurious or hazardous to the health of persons
                 occupying the Premises.  Without limiting the generality of
                 this Section, the Premises are, and during all applicable
                 limitation periods have been, free of asbestos except 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.  No part of the Premises has
                 been used for the generation, manufacture, handling, storage,
                 disposal, or management of Hazardous Substances.

                          (c)  Underground Storage Tanks.  The Premises do not
                 contain, and have never contained, any underground storage
                 tanks.  With respect to any underground storage tank listed in
                 the FNBC Disclosure Statement as an exception to the
                 foregoing, each such underground storage tank presently or
                 previously located on Premises is or has been maintained or
                 removed, as





                                      -31-

                 applicable, in compliance with all applicable Environmental
                 Laws, and has not been the source of any release of a
                 Hazardous Substance to the environment which has not been
                 remediated.

                          (d)  Absence of Contamination.  The Premises do not
                 contain and are not contaminated by any reportable quantity,
                 or any quantity in excess of applicable cleanup standards, of
                 a Hazardous Substance from any source.

                          (e)  Environmental Suits and Proceedings.  There is
                 no action, suit, investigation, liability, inquiry, or other
                 proceeding, ruling, order, notice of potential liability, or
                 citation involving FNBC or any of FNBC's Subsidiaries pending,
                 threatened, or previously asserted under, or as a result of
                 any actual or alleged failure to comply with any requirement
                 of, any Environmental Law.  Without limiting the generality of
                 this Section, there is no basis for any claim against or
                 involving FNBC or any of FNBC's Subsidiaries, or any of their
                 respective properties or assets, under Section 107 of CERCLA
                 or any similar provision of any other Environmental Law.

                 4.21.4  Loan Portfolio.  With respect to any real estate
         securing any outstanding loan or related security interest and any
         owned real estate acquired in full or partial satisfaction of a debt
         previously contracted:

                          (a)  Investigation.  FNBC and each of FNBC's
                 Subsidiaries have complied in all material respects with their
                 policies (as such policies may have been in effect from time
                 to time and as disclosed in the FNBC Disclosure Statement),
                 and all applicable laws and regulations, concerning the
                 investigation of each such property to determine whether or
                 not there exists or is reasonably likely to exist any
                 Hazardous Substance on, in, or under such property and whether
                 or not a release of a Hazardous Substance has occurred at or
                 from such property.

                          (b)  No Known Contamination.  To FNBC's knowledge, no
                 such property contains or is contaminated by any quantity of
                 any Hazardous Substance from any source.

         4.22  Duties as Fiduciary.  The Bank has performed all of its duties
in any capacity as trustee, executor, administrator, registrar, guardian,
custodian, escrow agent, receiver, or other fiduciary in a fashion that
complies in all material respects with all applicable laws, regulations,
orders, agreements, wills, instruments, and common law standards, the violation
of which would be material to its business, income, or financial condition.

         4.23  Investment Bankers and Brokers.  FNBC has employed the
investment banking firm of M. A. Schapiro & Co., Inc.  FNBC's only financial
obligation with respect to invest-





                                      -32-

<PAGE>   40
ment banking firms is the payment of fees and expenses as described in the FNBC
Disclosure Statement.  FNBC has not employed any other broker, finder, or
investment banker in connection with the Merger.  FNBC has no express or
implied agreement with any other person or company relative to any commission
or finder's fee payable with respect to the Merger.

         4.24  Related Persons.  For purposes of this Plan of Merger, the term
"FNBC RELATED PERSON" shall mean any director or executive officer of FNBC or
any of FNBC's Subsidiaries, their spouses and children, any person who is a
member of the same household as such persons, and any corporation, partnership,
proprietorship, trust, or other entity of which any such persons, alone or
together, have Control.

                 4.24.1  Control of Material Assets.  Other than in a capacity
         as a shareholder, director, or executive officer of FNBC or any of
         FNBC's Subsidiaries, no FNBC Related Person owns or controls any
         material assets or properties which are used in the business of FNBC
         or any of FNBC's Subsidiaries.

                 4.24.2  Contractual Relationships.  Other than ordinary and
         customary banking relationships, no FNBC Related Person has any
         contractual relationship with FNBC or any of FNBC's Subsidiaries.

                 4.24.3  Loan Relationships.  No FNBC Related Person has any
         outstanding loan or loan commitment from, or on whose behalf an
         irrevocable letter of credit has been issued by, FNBC or any of FNBC's
         Subsidiaries in a principal amount of $50,000 or more.

         4.25  Change in Business Relationships.  Neither FNBC nor any of
FNBC's Subsidiaries has notice, whether on account of the Merger or otherwise,
that (i) any customer, agent, representative, or supplier of FNBC or any of
FNBC's Subsidiaries intends to discontinue, diminish, or change its
relationship with FNBC or any of FNBC's Subsidiaries, the effect of which would
be material to the business of FNBC or any of FNBC's Subsidiaries; or (ii) any
executive officer of FNBC or any of FNBC's Subsidiaries intends to terminate
his or her employment.

         4.26  Insurance.  The FNBC Disclosure Statement contains true copies
of each policy of insurance presently in force with respect to the assets,
properties, premises, operations, and personnel of FNBC and each of FNBC's
Subsidiaries.  FNBC and each of FNBC's Subsidiaries maintains in full force and
effect insurance on its assets, properties, premises, operations, and personnel
in such amounts and against such risks and losses as are customary and adequate
for comparable entities engaged in the same business and industry.  There is no
unsatisfied claim of $25,000 or more under such insurance as to which the
insurance carrier has denied liability.  During the last five years, no
insurance company has canceled or refused to renew a policy of insurance
covering FNBC's or any of FNBC's Subsidiaries' assets, properties, premises,
operations, or personnel.

<PAGE>   41
         4.27  Books and Records.  The minutes contained in corporate minute
books and files of FNBC and each of FNBC's Subsidiaries (since it was acquired
by FNBC) properly and accurately record in all material respects all actions
actually taken by its shareholders, directors, and committees of directors.
The books, accounts, and records of FNBC and each of FNBC's Subsidiaries
reflect only actual transactions and have been maintained in all material
respects in the usual and regular manner, in accordance with generally accepted
accounting principles consistently applied, and in compliance with all
applicable laws and regulations.

         4.28  Loan Guarantees.  All guarantees of indebtedness owed to any of
FNBC's Subsidiaries, including but not limited to those of the Federal Housing
Administration, the Small Business Administration, and other state and federal
agencies, are valid and enforceable, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium, or other similar laws
affecting creditors' rights, and by the exercise of judicial discretion in
accordance with general principles applicable to equitable and similar
remedies, and except as would not be material to FNBC or any of FNBC's
Subsidiaries.

         4.29  Events Since December 31, 1993.  Neither FNBC nor any of FNBC's
Subsidiaries has, since December 31, 1993:

                 4.29.1  Business in Ordinary Course.  Conducted its business
         other than in the ordinary course, or incurred or become subject to
         any liability or obligation, except liabilities incurred in the
         ordinary course of business, and except for any single liability or
         for the aggregate of any group of related liabilities which do not
         exceed $50,000.

                 4.29.2  Strikes or Labor Trouble.  Experienced or, to the best
         knowledge of FNBC, been threatened by any strike, work stoppage,
         organizational effort, or other labor trouble, or any other event or
         condition of any similar character which has been or could reasonably
         be expected to be materially adverse to the business, income, or
         financial condition of FNBC or any of FNBC's Subsidiaries.

                 4.29.3  Discharge of Obligations.  Discharged or satisfied any
         lien or encumbrance, or paid any obligation or liability other than
         those shown on FNBC's December 31, 1993, consolidated financial
         statements or incurred after that date, other than in the ordinary
         course of business, except for such liens, encumbrances, liabilities,

                 4.29.4  Mortgage of Assets.  Mortgaged, pledged, or subjected
         to lien, charge, or other encumbrance any of its assets, or sold or

         encumbrances for indebtedness that do not in the aggregate exceed
         $50,000.





                                      -34-

<PAGE>   42
                 4.29.5  Extraordinary Transactions.  Entered into any
         transaction involving more than $50,000 in the aggregate, other than
         in the ordinary course of business, or incurred any other liabilities,
         obligations, liens, or encumbrances for indebtedness that in the
         aggregate exceed $50,000.

                 4.29.6  Contract Amendment or Termination.  Made or permitted
         any amendment or termination of any contract to which it is a party
         and which is material to the business, income, or financial condition
         of FNBC or any of FNBC's Subsidiaries, except as expressly provided in
         this Plan of Merger.

         4.30  Anticipated Changes.  No facts or circumstances specific to FNBC
and FNBC's Subsidiaries and not applicable to the banking industry in general
have been discovered from which it appears that there is a risk that there will
occur a materially adverse change in the financial condition, net income,
business, properties, operations, or prospects of FNBC or any of FNBC's
Subsidiaries.

         4.31  Reserve for Loan Losses.  The reserve for loan losses reflected
in FNBC's and FNBC's Subsidiaries' audited consolidated financial statements
for the period ended December 31, 1993, and Call Reports for the quarters ended
March 31, 1994 and June 30, 1994, was adequate to meet all reasonably
anticipated loan losses, net of recoveries related to loans previously charged
off.

         4.32  Loan Origination and Servicing.  In originating, underwriting,
servicing, and discharging loans, mortgages, land contracts, and other
contractual obligations, either for its own account or for the account of
others, the Bank has complied with all applicable terms and conditions of such
obligations and with all applicable laws, regulations, rules, contractual
requirements, and procedures with respect to such servicing, except for
incidents of noncompliance that would not, individually or in the aggregate,
have a material effect on the business, income, or financial condition of FNBC
or any of FNBC's Subsidiaries.

         4.33  Public Communications; Securities Offering.  No annual report,
quarterly report, proxy material, press release, or other communication
previously sent or released by FNBC or any of FNBC's Subsidiaries to FNBC's
stockholders or the public since January 1, 1991, was false or misleading with
respect to any material fact, or omitted to state any material fact necessary
to make the statements therein not misleading.

         4.34  No Insider Trading.  FNBC has reviewed its stock transfer
records since December 31, 1993, and has questioned its directors and executive
officers concerning known stock transfers since that date.  Based upon that
investigation, to the best of FNBC's knowledge, no director or officer of FNBC
or any of FNBC's Subsidiaries and no person related to any such director or
officer by blood or marriage and residing in the same household has since
December 31, 1993, purchased or sold, or caused to be purchased or sold, any
shares of FNBC Common Stock of which such director, officer, or related person
is or was the





                                      -35-

<PAGE>   43
record or beneficial owner as determined according to Rule 13d-3 issued under
the Securities Exchange Act of 1934, as amended (the "SECURITIES EXCHANGE
ACT"), during any period when FNBC was in possession of material nonpublic
information.

         4.35  Continuity of Interest.  To the best of FNBC's knowledge, there
is no plan or intention by the stockholders of FNBC who own FNBC Common Stock
to sell, exchange, or otherwise dispose of a number of shares of Old Kent
Common Stock received in the transaction that would reduce the FNBC
stockholders' ownership of Old Kent Common Stock to a number of shares having a
value, as of the Effective Time of the Merger, of less than 50 percent of the
value of all of the formerly outstanding FNBC Common Stock as of the same time.
For purposes of this representation, shares of FNBC Common Stock exchanged for
cash in lieu of fractional shares will be treated as outstanding FNBC Common
Stock at the Effective Time of the Merger.  Shares of FNBC Common Stock and
shares of Old Kent Common Stock held by FNBC stockholders and otherwise sold,
redeemed, or disposed of before or after the transaction will be considered in
making this representation.

         4.36  Pooling of Interests Accounting Qualification.  Neither FNBC nor
any of FNBC's Subsidiaries owns any shares of Old Kent Common Stock, any
securities convertible into such stock, or any rights to acquire such stock,
except for any which may be held in a fiduciary capacity for a customer as to
which FNBC or any of FNBC's Subsidiaries has no beneficial interest.  Neither
FNBC nor any of FNBC's Subsidiaries has during the past 2 years acquired any
shares of FNBC Common Stock, any securities convertible into such stock, or any
other rights to acquire such stock, except for any which may be held in a
fiduciary capacity for a customer as to which FNBC or any of FNBC's
Subsidiaries has no beneficial interest, and except as permitted for purposes
other than a business combination under the pooling of interests method of
accounting, and no more than a normal number of shares have been acquired for
such permissible purposes.

         4.37  True and Complete Information.  No schedule, statement, list,
certificate, or other information furnished or to be furnished by FNBC in
connection with this Plan of Merger, including the FNBC 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.

         4.38  Truth and Completeness of Representations and Warranties.

                 4.38.1  True at the Closing.  FNBC further warrants that its
         representations and warranties in this Plan of Merger will be true in
         all material respects at the Closing.  All of such representations and
         warranties made with respect to specified dates or events shall still
         be true at the Closing in all material respects with respect to such
         dates or events.

                 4.38.2  Untrue Representations and Warranties.  During the
         term of this Plan of Merger, if FNBC becomes aware of any facts or of
         the occurrence or impending occurrence of any event which would cause
         one or more of FNBC's representations and warranties contained in this
         Plan of Merger to become untrue, or would have caused one or more of
         such representations and warranties (except in the case of
         representations and warranties expressly made only as of the execution
         of this Plan of Merger) to be untrue had such facts been known or had
         such event occurred prior to the execution of this Plan of Merger,
         then:

                          (a)  Notice.  FNBC shall immediately give detailed
                 written notice thereof to Old Kent; and

                          (b)  Remedy Unless Waived.  FNBC shall use all
                 reasonable efforts to change such facts or events to make such
                 representations and warranties true, unless the same shall
                 have been waived in writing by Old Kent.

         Merger.  For the purposes of this Section 5.5 (Data Processing
         Arrangements) the M & I Agreement shall not be considered to be
         terminated unless and until Old Kent and FNBC shall have expressly
         agreed upon the amount of the aggregate combined cost to Old Kent and
         FNBC in cash, fair market value of contract concessions, and fair
         market value of other consideration (together, the "TERMINATION COST")
         to be incurred to terminate the M & I Agreement, or that the
         Termination Cost is less than $250,000.  The Purchase Price Per Share
         as set forth in Section 2.1.1 (Conversion of FNBC Common Stock) shall
         be adjusted, depending on the results of such negotiation, if and as
         set forth below:

                          (a)     If the M & I Agreement is terminated on terms
                 reasonably acceptable to both Old Kent and FNBC at a
                 Termination Cost of $250,000 or less, then there shall be no
                 adjustment to the Purchase Price Per Share on account of the M
                 & I Agreement.

                          (b)     If the M & I Agreement is terminated on terms
                 reasonably acceptable to both Old Kent and FNBC at a
                 Termination Cost in excess of $250,000, then the Purchase
                 Price Per Share shall be reduced by the lesser of (i) an
                 amount determined by dividing (x) two-thirds of the difference
                 between the Termination Cost and $250,000, by (y) 2,434,060;
                 or (ii) $.40.

                          (c)     If, as of the close of business on the day
                 preceding the date of the Closing, the M & I Agreement has not
                 been terminated on terms reasonably acceptable to both Old
                 Kent and FNBC, then the Purchase Price Per Share shall be
                 reduced by $.40.

                 5.5.2    Other Arrangements.  Until the Effective Time of the
         Merger, FNBC shall advise Old Kent of all anticipated renewals or
         extensions of existing data processing services agreements with
         independent vendors.  FNBC agrees to cooperate with Old Kent in
         negotiating with those vendors the length of any extension or





                                      -46-

<PAGE>   54
         renewal term of those agreements, which, unless otherwise agreed with
         Old Kent, shall not exceed one year from the date of renewal.  FNBC
         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 FNBC and Old Kent.

         5.6   Affiliates.  The FNBC Disclosure Statement and the update to the
FNBC Disclosure Statement shall identify every person who may, to FNBC's
reasonable knowledge, be deemed to be an "affiliate" of FNBC for purposes of
Rule 145 under the Securities Act of 1933, as amended (the "SECURITIES ACT").
FNBC shall cause its counsel to deliver to each person who is identified as an
affiliate, on or prior to the Effective Time of the Merger, advice with respect
to such person's obligations under the Securities Act and the regulations
issued thereunder with respect to disposition of securities of Old Kent.
Further, FNBC shall use all reasonable efforts to cause each person who is
identified as an affiliate to deliver to Old Kent on or prior to the Effective
Time of the Merger a written agreement, satisfactory to Old Kent, that such
person shall not offer to sell or otherwise dispose of any shares of Old Kent
Common Stock issued to such person pursuant to the Merger in violation of the
Securities Act or the regulations thereunder, or prior to publication of
financial results of the post-Merger combined operations of Old Kent covering a
period of at least 30 days.

         5.7   Maintenance of Insurance.  FNBC shall use all reasonable efforts
to obtain renewal of the directors' and officers' liability and corporation
reimbursement insurance in effect on the execution of this Plan of Merger on
terms and conditions reasonably agreeable to FNBC.  FNBC shall consult with Old
Kent regarding any renewals of, and the premiums to be paid for, such insurance
prior to taking any action to renew or terminate such insurance.  If FNBC's
directors and officers liability insurance policy is canceled or not renewed by
the issuer during the term of this Plan of Merger, FNBC shall, at Old Kent's
option, purchase the discovery period offered under the policy.

         5.8   Competing Proposals.  Neither FNBC nor any of FNBC'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.  Without limiting the foregoing:

                 5.8.1  No Solicitation.  Neither FNBC nor any of FNBC's
         Subsidiaries, nor any of their respective directors, officers,
         employees, investment bankers, representatives, or agents, shall
         solicit, encourage, or negotiate 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 FNBC or any of FNBC's Subsidiaries
         other than the Merger (a "BUSINESS COMBINATION").

<PAGE>   55
                 5.8.2  Communication of Other Proposals.  FNBC shall cause
         written notice to be delivered to Old Kent promptly upon receipt of
         any solicitation, offer, proposal, or expression of interest (a
         "PROPOSAL") concerning a Business Combination.  Such notice shall
         contain the material terms and conditions of the Proposal to which
         such notice relates or shall contain a copy of FNBC's unequivocal
         rejection of the Proposal in the form actually delivered to the person
         from whom the Proposal was received.  Thereafter, FNBC shall promptly
         notify Old Kent of any material changes in the terms, conditions, and
         status of any Proposal.

                 5.8.3  Furnishing Information.  Neither FNBC nor any of FNBC's
         Subsidiaries, nor any of their respective directors, officers,
         employees, investment bankers, representatives, or agents, shall
         furnish any nonpublic information concerning FNBC or any of FNBC's
         Subsidiaries to any person who is not affiliated or under contract
         with FNBC or Old Kent, except as required by applicable law or
         regulations.

         5.9   Redemption of Rights.  The Board of Directors of FNBC shall take
all action necessary to redeem the FNBC Rights outstanding under the FNBC
Rights Agreement at a redemption price of $.01 per FNBC Right in cash, which
redemption shall become effective immediately prior to the Effective Time of
the Merger.  Following such redemption, FNBC shall have no obligation under the
FNBC Rights or the FNBC Rights Agreement and the holders shall have no rights
under the FNBC Rights or the FNBC Rights Agreement following such time, except,
in each case, with respect to the payment of the redemption price.

         5.10    Insurance Company.  Notwithstanding any other provision of
this Plan of Merger, FNBC may liquidate or sell the Insurance Company for a
price not less than the stockholders' equity of the Insurance Company or such
other price to which Old Kent may reasonably agree.


                                   ARTICLE VI

                             ADDITIONAL AGREEMENTS

         6.1   Registration Statement.  As soon as is reasonably practical, Old
Kent agrees to prepare and file with the SEC under the Securities Act the
Registration Statement and the related Prospectus and Proxy Statement included
as a part thereof covering the issuance by Old Kent of the shares of Old Kent
Common Stock as contemplated by this Plan of Merger, together with such
amendments as may reasonably be required for the Registration Statement to
become effective.  Old Kent agrees to provide FNBC with the opportunity to
review and comment upon the Registration Statement, each amendment to the
Registration Statement, and each form of the Prospectus and Proxy Statement
before filing.  Old Kent will make such amendments and file such supplements
thereto as FNBC may reasonably request.  Old





                                      -48-

<PAGE>   56
Kent agrees to provide FNBC with copies of all correspondence received from the
SEC with respect to the Registration Statement and its amendments and with all
responsive correspondence to the SEC.  Old Kent agrees to notify FNBC of any
stop orders or threatened stop orders with respect to the Registration
Statement.  FNBC agrees to provide all necessary information pertaining to FNBC
and FNBC's Subsidiaries promptly upon request, and to use its best efforts to
obtain the cooperation of FNBC's independent accountants and attorneys, in
connection with the preparation of the Registration Statement.

         6.2   Other Filings.  Old Kent agrees to prepare and file, as soon as
is reasonably practical, with the Federal Reserve Board, the State of Michigan,
the State of Delaware, the State of Arizona, and other regulatory agencies all
documents in connection with the transactions contemplated by this Plan of
Merger.  Old Kent agrees to provide FNBC with the opportunity to review and
comment upon such documents before filing and to make such amendments and file
such supplements thereto as FNBC may reasonably request.  Old Kent shall
provide FNBC with copies of all correspondence received from these agencies and
all responsive correspondence sent to these agencies.

         6.3   Press Releases.  FNBC and Old Kent shall consult with each other
with respect to the form and substance of any press release, Form 8-K, or other
public disclosure of matters related to this Plan of Merger.

         6.4   Indemnification.  Old Kent acknowledges that any and all rights
to indemnification now existing in favor of the employees, agents, directors
and officers of FNBC and each of FNBC's Subsidiaries under their respective
certificates or articles of incorporation, charters, articles of association or
bylaws shall survive the Merger and shall continue with respect to acts or
omissions occurring prior to the Effective Time of the Merger with the same
force and effect as prior to the Effective Time of the Merger.  In the event of
any claim or litigation giving rise to such indemnification, Old Kent will
provide the indemnified party with access to and the right to copy all
documents and other information reasonably required for the defense of the
litigation, subject to reasonable precautions to prevent inappropriate use or
disclosure of such documents and information, and will reasonably cooperate in
the defense of such litigation.

         6.5   Miscellaneous Agreements and Consents.  Subject to the terms and
conditions of this Plan of Merger, each of the parties agrees to use all
reasonable efforts to take, or cause to be taken, all actions, and to do, or
cause to be done, all things necessary, proper, or advisable under applicable
laws and regulations to consummate and make effective the transactions
contemplated by this Plan of Merger.  Old Kent and FNBC will use all reasonable
efforts to obtain consents of all third parties and governmental bodies
necessary or desirable for the consummation of the Merger.

         6.6   Stock Options.  Before the Effective Time of the Merger, FNBC
will amend, if necessary and subject to employee consent, the terms of all of
its outstanding employee stock





                                      -49-

<PAGE>   57
options identified in Section 4.4.2 (No Other Capital Stock) so that they will
become, if and when the Merger becomes effective, options to acquire, for an
equivalent price, the number of shares of Old Kent Common Stock that would have
been acquired if the options to acquire FNBC Common Stock had been exercised
immediately prior to the Effective Time of the Merger.  At the Closing, Old
Kent will grant to each non-employee director of FNBC then serving on FNBC's
Board of Directors replacement options to purchase, for an equivalent price and
subject to the same vesting requirements with respect to service as a director
of the Bank or as a director or advisory director of any successor to the Bank,
the number of shares of Old Kent Common Stock that would have been acquired if
his or her options to acquire FNBC Common Stock (including shares as to which
his or her options are not then vested) had been exercised immediately prior to
the Effective Time of the Merger, in consideration for the written waiver
executed by each such non-employee director of FNBC of any rights that he or
she may have under then outstanding options issued by FNBC to purchase shares
of FNBC Common Stock.  The options shall in all other respects contain
substantially the same terms and conditions as they do presently.  Old Kent
agrees to honor the options according to their terms and to register the
options and the shares acquired upon their exercise with the SEC on Form S-8,
if and to the extent that they are eligible for registration under that form.


         6.7   ESOP.  The ESOP shall be terminated effective as of the Closing.
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 Bank
Stock Loan Agreement dated as of June 7, 1994, between the ESOP, FNBC, and
Bankers' Bank of Illinois (the "BANK STOCK LOAN AGREEMENT"), and that any
assets left in the suspense account after repayment of the loan will be
allocated among the participants 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, the
participants in the ESOP will have the option to transfer or roll over their
ESOP accounts into the Old Kent Thrift Plan.

         6.8   Exchange of Financial Information.  Subject to Section 6.9
(Investigation):

                 6.8.1  Quarterly Information.  FNBC and Old Kent shall each,
         as promptly as practicable, deliver to the other copies of each
         quarterly consolidated financial statement prepared for distribution
         to stockholders or shareholders, respectively, after the date of this
         Plan of Merger.

                 6.8.2  FNBC Information.  After the execution of this Plan of
         Merger until the Effective Time of the Merger, FNBC shall promptly
         deliver to Old Kent copies of:

                          (a)  Each monthly internal financial report prepared
                 with respect to FNBC and each of FNBC's Subsidiaries on a
                 consolidated or unconsolidated





                                      -50-

<PAGE>   58
                 basis.  FNBC represents and warrants that such information
                 shall be consistent with the fundamental information as used
                 for internal purposes by FNBC in the management of its
                 consolidated business; and

                          (b)  Each financial report or statement submitted to
                 regulatory authorities for FNBC and each of FNBC's 
                 Subsidiaries.

                 6.8.3  SEC Filings.  After the execution of this Plan of
         Merger until the Effective Time of the Merger, Old Kent and FNBC shall
         each promptly deliver to the other copies of all reports on Form 10-K
         and Form 10-Q, and all other reports filed with the SEC.

         6.9   Investigation.

                 6.9.1  Old Kent's Access to Information.  For the purpose of
         permitting an examination of FNBC by such of Old Kent's officers,
         attorneys, accountants, and representatives as have a "need to know"
         for the purposes of Old Kent's evaluation of the Merger, provided that
         Old Kent shall cause such parties to agree to maintain the
         confidentiality of the information as provided in this Plan of Merger,
         while this Plan of Merger is in effect, FNBC shall:

                          (a)  Permit, and shall cause each of FNBC's
                 Subsidiaries to permit, full access to their respective
                 properties, books, and records at reasonable times;

                          (b)  Use reasonable efforts to cause its and each of
                 FNBC's Subsidiaries' officers, directors, employees,
                 accountants, and attorneys to cooperate fully, for the purpose
                 of permitting a complete and detailed examination of such
                 matters by Old Kent's officers, attorneys, accountants, and
                 representatives; and

                          (c)  Furnish to Old Kent, upon request, any
                 information reasonably requested respecting its and each of
                 FNBC's Subsidiaries' properties, assets, business, and
                 affairs.

                 6.9.2  Consent to Disclose.  Old Kent acknowledges that
         certain information may not be disclosed by FNBC or FNBC's
         Subsidiaries without the prior written consent of persons not
         affiliated with FNBC or any of FNBC's Subsidiaries.  If such
         information is requested by Old Kent, then FNBC shall use, or cause
         each of FNBC's Subsidiaries to 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.





                                      -51-

<PAGE>   59
                 6.9.3  FNBC's Access to Information.  For the purpose of
         permitting an examination of Old Kent by such of FNBC's officers,
         attorneys, accountants, and representatives as have a "need to know"
         for the purposes of FNBC's evaluation of the Merger, provided that
         FNBC shall cause such parties to agree to maintain the confidentiality
         of the information as provided in this Plan of Merger, while this Plan
         of Merger is in effect, Old Kent shall:

                          (a)  Permit reasonable access to its properties,
                 books, and records at reasonable times;

                          (b)  Use reasonable efforts to cause its officers,
                 directors, employees, accountants, and attorneys to cooperate
                 fully; and

                 reasonably requested respecting its properties, assets,
                 business, and affairs.

                 6.9.4  Confidentiality.  Except as provided in Section 6.9.6
         (Other Information), while this Plan of Merger is in effect and at all
         times thereafter, Old Kent and FNBC each agree to treat as strictly
         confidential and agree not to divulge to any other person, natural or
         corporate (other than employees of, and attorneys, accountants, and
         financial advisers for, such party who are reasonably believed to have
         a need for such information in connection with the Merger), and not to
         make any business use not related to the Merger of, any financial
         statements, schedules, contracts, agreements, instruments, papers,
         documents, or other information relating to the other party and the
         other party's subsidiaries which it may come to know as a direct
         result of a disclosure by the other party or the other party's
         subsidiaries, or which may come into its possession directly as a
         result of and during the course of such investigation.

                 6.9.5  Return of Materials.  Upon the termination of this Plan
         of Merger, Old Kent and FNBC 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 notes and
         summaries of such written materials, in connection with such
         investigation, including any and all copies of any of the foregoing.
         Old Kent and FNBC each agree to preserve intact all such materials
         which are returned to them and to make such materials reasonably
         available upon request or subpoena for a period of not less than five
         years from the termination of this Plan of Merger or such longer or
         shorter period of time as they may mutually agree.

                 6.9.6  Other Information.  The provisions of this Section 6.9
         (Investigation) shall not preclude Old Kent or FNBC, or their
         respective subsidiaries, from using or disclosing information which
         is: (i) readily ascertainable from public information or trade
         sources; (ii) known by it before the commencement of discussions
         between the





                                      -52-

<PAGE>   60
         parties or subsequently developed by it or its subsidiaries
         independent of any investigation under this Plan of Merger or received
         from a third party not under any obligation to FNBC or Old Kent, or
         their respective subsidiaries, to keep such information confidential;
         or (iii) reasonably required to be included in any filing or
         application required by any governmental or regulatory agency,
         including without limitation Old Kent's application or applications to
         the Federal Reserve Board, Old Kent's or FNBC's reports on Form 10-K
         and Form 10-Q filed with the SEC, and Old Kent's or FNBC's annual
         report and proxy statement.  Old Kent shall permit FNBC to review Old
         Kent's application or applications to the Federal Reserve Board and
         the State of Arizona with respect to the purchase of the Insurance
         Company prior to filing and FNBC may reasonably request that sensitive
         or competitive information be separately filed as confidential in
         accordance with instructions, rules, and regulations promulgated by
         such agencies.

                 6.9.7  Insider Trading.  Old Kent and FNBC shall take
         responsible steps to assure that any person who receives nonpublic
         information concerning the other party pursuant to this Section 6.9
         (Investigation) will not buy or sell, or advise other persons to buy
         or sell, the other party's stock until such information is disclosed
         to the public.

         6.10   Environmental Investigation.  Old Kent shall engage a mutually
acceptable environmental consultant to conduct a preliminary ("PHASE I")
environmental assessment of each of the parcels of real estate used in the
operation of FNBC's or any of FNBC's Subsidiaries' businesses and, at Old
Kent's option, any other real estate owned.  FNBC and FNBC's Subsidiaries shall
provide reasonable assistance, including site access, to the consultant for
purposes of conducting the Phase I assessments.  The fees and expenses of the
consultant with respect to the Phase I assessments shall be paid by Old Kent.
The consultant shall complete and deliver a report of the Phase I assessments
not later than 60 days after the date of this Plan of Merger.  Old Kent shall
have a period of 20 business days from the date it receives the report of the
consultant to consider the report and to notify FNBC in writing if any
environmental conditions are found or indicated by the report which may be
contrary to the representations and warranties set forth in Section 4.21
(Environmental Matters), without regard to any exceptions that may be contained
in the FNBC Disclosure Statement.  With respect to any conditions identified by
Old Kent in its notice to FNBC, Old Kent shall obtain from one or more mutually
acceptable consultants or contractors, as appropriate, an estimate of the cost
of any further environmental investigation, sampling, analysis, remediation, or
other follow-up work that may be necessary to address those conditions in
accordance with applicable Environmental Laws.  Old Kent shall forward copies
of any such estimates to FNBC upon receipt.

                 6.10.1   Mutual Agreement.  Upon receipt of the estimate of
         the costs of all follow-up work to the Phase I assessments, the
         parties shall have a period of 30 days in which they shall attempt to
         agree upon a course of action for further





                                      -53-

<PAGE>   61
         investigation and remediation of any environmental condition found to
         exist or indicated by the report of the consultant.  All work plans
         for any post-Phase I assessment activities, or any removal or
         remediation actions that may be performed, shall be mutually
         satisfactory to Old Kent and FNBC.  If the work plans or removal or
         remediation actions would entail a material cost to complete, Old Kent
         and FNBC shall discuss a mutually acceptable modification to this Plan
         of Merger.  Old Kent and FNBC shall cooperate in the review, approval,
         and implementation of all work plans.  The Board of Directors of FNBC
         may, at its option, extend the period of time set forth in this
         Section 6.10.1 (Mutual Agreement) for the parties to attempt to agree
         upon a course of action and/or discuss a mutually acceptable
         modification to this Plan of Merger.

                 6.10.2   Old Kent's Right to Abandon.  If the parties are
         unable to agree upon a course of action for further investigation and
         remediation of an environmental condition or issue raised by an
         environmental assessment and/or a mutually acceptable modification to
         this Plan of Merger, and the condition or issue is not one for which
         it can be determined to a reasonable degree of certainty that the risk
         and expense to which Old Kent and its subsidiaries would be subject as
         an owner or operator of the property involved can be quantified and
         limited to an immaterial amount, then Old Kent may abandon this Plan
         of Merger at any time during such 30-day period or any extension
         thereof pursuant to Section 9.2.10 (Environmental Conditions).

         6.11  Pooling Qualification.  Old Kent and FNBC each agree that,
except as expressly provided in this Plan of Merger, while this Plan of Merger
is in effect, it shall not take or fail to take, or cause to be taken or fail
to cause to be taken, any action if the result would be to present a material
risk that the Merger would become disqualified for the pooling of interests
method of accounting by Old Kent, including without limitation:

                 6.11.1  No Stock Purchases.  Neither Old Kent nor any of Old
         Kent's subsidiaries, nor FNBC nor any of FNBC's Subsidiaries,
         respectively, shall acquire any shares of Old Kent Common Stock, FNBC
         Common Stock, any securities convertible into such stock or any other
         rights to acquire such stock, except in a fiduciary capacity for a
         customer as to which it has no beneficial interest, and except as
         permitted for purposes other than a business combination under the
         pooling of interests method of accounting and provided that no more
         than a permitted number of shares have been acquired for such
         permissible purposes; and

                 6.11.2  No Change of Equity Interest.  Neither Old Kent nor
         FNBC, respectively, shall in any manner change the equity interest of
         Old Kent Common Stock or FNBC Common Stock, respectively, between the
         date of this Plan of Merger and the consummation of the Merger,
         including without limitation distributions (other than ordinary and
         customary cash dividends) to shareholders and stockholders and
         additional issuances, exchanges, and retirements of securities.

         representations and warranties made with respect to specified dates or
         events need only to have been true in all material respects as of such

         change.

                 7.1.2  Compliance with Agreements.  FNBC and FNBC's
         Subsidiaries shall have performed and complied with all agreements,

         10,000,000 shares divided into two classes as follows:

                          (a)     8,000,000 shares of common stock, $3.125 par
                 value, of which the number of shares specified in the opinion
                 are then legally issued and outstanding, and non-assessable;
                 and

                          (b)     2,000,000 shares of preferred stock, $.01 par
                 value, none of which are issued and outstanding.

                 7.2.4  Issuance of Shares.  Except as disclosed in such
         opinion, to counsel's knowledge:

                          (a)  Since the date and time of the execution of this
                 Plan of Merger, no additional shares of capital stock have
                 been authorized for issuance or issued by FNBC.

                          (b)  There are no other outstanding subscriptions,
                 options, warrants, rights to acquire any capital stock of
                 FNBC, or agreements to which FNBC is a party or by which it is
                 bound to issue capital stock, except as set forth in the FNBC
                 Disclosure Statement or in such opinion.

                 7.2.5  Organization of Subsidiaries.  First National Bank in
         Macomb County and Bankers Fund Life Insurance Company are each duly
         incorporated, validly existing, and in good standing under the laws of
         the United States of America and the State of Arizona, respectively.
         Each of FNBC's Subsidiaries possesses all corporate authority to
         conduct and carry on its business, substantially where and as it
         conducts it, under all applicable federal and state laws.  Each of
         FNBC's Subsidiaries is qualified or admitted to conduct its business
         in the State of Michigan.  To the best of counsel's knowledge, neither
         of FNBC's Subsidiaries is required to be qualified in any other state.

         its terms, except as enforceability may be limited by bankruptcy,
         insolvency, reorganization, moratorium, or other similar laws
         affecting creditors' rights, and by the exercise of judicial
         discretion in accordance with general principles applicable to
         equitable and similar remedies.

                 7.2.8  All Approvals Received.  To the best of counsel's
         knowledge, all approvals, consents, authorizations, or modifications
         as may be required to permit the performance by FNBC of its

         requirements of the blue sky laws of any state with respect to (i) the
         issuance of Old Kent Common Stock pursuant to this Plan of Merger; and
         (ii) the registration or qualification of securities brokers, dealers,
         or agents.

                 7.2.9  All Actions Taken.  All other actions and proceedings

         validly taken.

                 7.2.10  No Conflict, Breach, or Violation.  The execution,
         delivery, and performance of this Plan of Merger by FNBC, and the
         consummation by FNBC of the transactions contemplated by this Plan of

         or result in any breach or violation of, or default under (i) any
         provision of the Certificate of Incorporation or Bylaws of FNBC; (ii)
         any statute, code, ordinance, rule, or regulation; (iii) to the best
         of counsel's knowledge, any judgment, order, writ, arbitral award,
         decree, or injunction applicable to FNBC or any of FNBC's
         Subsidiaries; or (iv) to the best of counsel's knowledge, any
         mortgage, agreement, lease, commitment, indenture, or other instrument

<PAGE>   65
         required from any person pursuant to any contract or agreement to
         which FNBC or any of FNBC's Subsidiaries is a party or subject, or by
         which FNBC or any of FNBC's Subsidiaries is bound, and which has been
         provided to counsel in connection with this Plan of Merger, have been
         obtained, except as disclosed in the FNBC Disclosure Statement or in
         such opinion.

                 7.2.11  No Litigation.  Except as disclosed in the FNBC
         Disclosure Statement or in such opinion, counsel does not know of any
         action, suit, proceeding, claim, counterclaim, arbitration, or
         investigation pending or threatened against or relating to (i) the
         directors or officers of FNBC or any of FNBC's Subsidiaries in their
         capacities as such; or (ii) FNBC or FNBC's Subsidiaries, or its or
         their respective properties or businesses, which challenges the
         Merger, or which may result in any liability to FNBC or any of FNBC's
         Subsidiaries which may exceed $100,000 and which would have a material
         adverse effect on the business, income, or financial condition of FNBC
         or any of FNBC's Subsidiaries.

                 In rendering its opinion, counsel may rely on certificates of
governmental officials and officers of FNBC or FNBC's Subsidiaries,
certificates of FNBC's transfer agent, and opinions of other counsel as to the
laws of jurisdictions in which counsel is not licensed to practice law, and
such other evidence as counsel for FNBC may reasonably deem necessary or
desirable.  Any certificates (other than those of governmental officials) or
legal opinions upon which FNBC's counsel may rely shall also be addressed to
Old Kent and Old Kent shall be entitled to rely thereon.  As to each matter
with respect to which FNBC's counsel relies upon a legal opinion rendered by
other counsel, FNBC's counsel shall state that FNBC's counsel has no knowledge
of any fact or circumstance that would render such other counsel's opinion
incorrect or misleading.  In addition, Old Kent may, in its reasonable
discretion, require opinions from other legal counsel who have represented FNBC
or any of FNBC's Subsidiaries with respect to the matters described in Section
7.2.11 (No Litigation).

         this Plan of Merger and the consummation of the Merger.

                 7.3.2  Stockholder.  Evidence reasonably satisfactory to Old

claim, arbitration, or investigation pending or threatened:  (i) against or
relating to FNBC or any of FNBC's Subsidiaries or its or their respective
properties or businesses which may result in any liability to FNBC or any of

         constitute a reorganization within the meaning of Section 368(a)(1)(A)
         of the Internal Revenue Code, and Old Kent and FNBC will each be a
         "party to a reorganization" within the meaning of Section 368(b) of
         the Internal Revenue Code.

                 7.6.2    The basis of the FNBC assets in the hands of Old Kent
         will be the same as the basis of those assets in the hands of FNBC
         immediately prior to the Merger.

                 7.6.3    No gain or loss will be recognized to Old Kent on the
         receipt by Old Kent of the assets of FNBC in exchange for Old Kent
         Common Stock and the assumption by Old Kent of the liabilities of
         FNBC.

                 7.6.4    The holding period of the assets of FNBC in the hands

with respect to rights under the Bank's Supplemental Executive Retirement Plan.

obtained and delivered to Old Kent such consents, amendments, or supplemental

necessary or advisable to confirm that neither the execution of this Plan of
Merger nor consummation of the Merger will result in any default, penalty, or
acceleration of indebtedness under the Bank Stock Loan Agreement, or any
related pledge agreement, security agreement, note, or other agreement.

         representations and warranties shall then be true in all material
         respects or, if one or more representations or warranties shall then
         be untrue, the cumulative effect of all untrue representations and

         with respect to specified dates or events need only to have been true

         valid and binding obligation of Old Kent, enforceable in accordance
         with its terms, except as enforceability may be limited by bankruptcy,

         businesses, which challenges the Merger, or which may result in any
         liability to Old Kent which may exceed $100,000 and which would have a
         material adverse effect on the business, income, or financial

         8.5   Tax Matters.  FNBC shall have received an opinion of counsel for
Old Kent, reasonably satisfactory in form and substance to FNBC's counsel,
substantially to the effect that:

                 8.5.1  No gain or loss will be recognized by the stockholders
         of FNBC who receive shares of Old Kent Common Stock in exchange for
         all of their shares of FNBC Common Stock, except to the extent of any
         cash received in lieu of a fractional share of Old Kent Common Stock.

                 8.5.2  The basis of the Old Kent Common Stock to be received
         by stockholders of FNBC will, in each instance, be the same as the
         basis of the respective shares of FNBC Common Stock surrendered in
         exchange therefor.

                 8.5.3  The holding period of the Old Kent Common Stock
         received by stockholders of FNBC will, in each instance, include the
         period during which the FNBC Common Stock surrendered in exchange
         therefor was held, provided that the FNBC Common Stock was, in each
         instance, held as a capital asset in the hands of the stockholder of
         FNBC at the Effective Time of the Merger.

been declared effective by the SEC and shall not be subject to a stop order or

A. Schapiro & Co., Inc., or another financial expert reasonably acceptable to
FNBC, dated approximately the date of the Prospectus and Proxy Statement, to
the effect that the terms of the Merger are fair to FNBC's stockholders from a
financial point of view as of that date and such opinion shall not have been
subsequently withdrawn.


                                   ARTICLE IX

                             ABANDONMENT OF MERGER

                 This Plan of Merger may be terminated and the Merger abandoned
at any time prior to the Effective Time of the Merger (notwithstanding that
approval of this Plan of Merger by the stockholders of FNBC may have previously
been obtained) as follows:

         9.1   Mutual Abandonment Prior to Effective Time of the Merger.  This
Plan of Merger may be terminated and the Merger abandoned by mutual consent of
the Boards of Directors, or duly authorized committees thereof, of Old Kent and
FNBC.

<PAGE>   72
         9.2   Old Kent's Rights to Terminate.  This Plan of Merger may be
terminated and the Merger abandoned by the Board of Directors, or a duly
authorized committee thereof, of Old Kent under any of the following
circumstances:

                 9.2.1  FNBC Disclosure Statement; Preclosing Investigation,
         Etc.  Old Kent shall have reasonably determined that:

                          (a)  Any exception to FNBC's representations and
                 warranties or any other information set forth in the FNBC
                 Disclosure Statement is material to the transaction and
                 reasonably unacceptable to Old Kent;

                          (b)  Based upon Old Kent's preclosing investigation
                 of FNBC, there exists any set of facts or circumstances
                 materially adverse to the financial condition, net income,
                 business, properties, operations, or prospects of FNBC or any
                 of FNBC's Subsidiaries; or

                          (c)  FNBC or any of FNBC's Subsidiaries is exposed to
                 risks or the Merger would expose Old Kent to risks that in the
                 reasonable judgment of Old Kent are not acceptable economic
                 and business risks;

         provided that Old Kent notifies FNBC of such abandonment and
         termination not later than the last to occur of (i) 21 business days
         after Old Kent receives the FNBC Disclosure Statement, and (ii) 30
         business days after the date of the execution of this Plan of Merger.

                 9.2.2  Breach of Warranty.  One or more of the representations
         and warranties made by FNBC in this Plan of Merger shall have been
         discovered to be or to have become untrue and the cumulative effect of
         all such untrue representations and warranties is material relative to
         the business, income, or financial condition of FNBC and FNBC's
         Subsidiaries on a consolidated basis.

                 9.2.3  Breach of Covenant.  FNBC shall have committed one or
         more breaches of any provision of this Plan of Merger which would in
         the aggregate be material; provided, that, if such breach or breaches
         can be cured, Old Kent shall have given FNBC specific notice of the
         breach or breaches in writing and FNBC shall have not cured such
         breach or breaches to the reasonable satisfaction of Old Kent within
         30 days of receipt of such notice.

                 9.2.4  Upset Date.  The Merger has not yet become effective on
         or before July 31, 1995.





                                      -65-

<PAGE>   73
                 9.2.5  Injunction.  A final unappealable injunction or other
         judgment shall have been issued by a court of competent jurisdiction
         restraining or prohibiting consummation of the Merger.

                 9.2.6  No Stockholder Approval.  The stockholders of FNBC have
         failed to ultimately adopt this Plan of Merger at an annual or special
         meeting or adjournments thereof, called and held for that purpose, and
         such meeting has been finally adjourned.

                 9.2.7  No Regulatory Approval.  The Federal Reserve Board or
         its delegate shall have refused to approve the Merger, or the State of
         Arizona shall have refused to grant any necessary approval to the
         change in control of the Insurance Company.

                 9.2.8  Adverse Change.  There has occurred any change from
         that which existed on December 31, 1993, in the financial condition of
         FNBC or any of FNBC's Subsidiaries which is materially adverse to the
         business, income, or financial condition of FNBC and FNBC's
         Subsidiaries on a consolidated basis.

                 9.2.9  Affiliate Agreements.  FNBC fails to obtain from each
         person who is or becomes an affiliate of FNBC on or after the date of
         this Plan of Merger a duly authorized and executed Affiliate
         Agreement, substantially in the form previously provided to FNBC by
         Old Kent or otherwise reasonably acceptable to Old Kent, to be
         delivered to Old Kent (i) within 60 days of the date of this Plan of
         Merger with respect to all persons who are affiliates of FNBC on the
         date of this Plan of Merger; and (ii) within 60 days of the date on
         which a person becomes an affiliate of FNBC with respect to all
         persons who become affiliates after the date of this Plan of Merger.
         If Old Kent in its discretion considers any person to be an affiliate
         of FNBC, and FNBC did not consider such person to be an affiliate of
         FNBC, then FNBC shall have a period of 60 days in which to obtain and
         deliver to Old Kent a duly authorized and executed Affiliate Agreement
         from such person after receipt of written notice from Old Kent
         identifying such person as an affiliate.

                 9.2.10  Environmental Conditions.  If Old Kent has notified
         FNBC of any environmental conditions found or indicated or issues
         raised by the Phase I environmental assessments pursuant to Section
         6.10 (Environmental Investigation) and the parties are unable to agree
         upon a course of action for further investigation and remediation of
         such environmental condition or issue raised by an environmental
         assessment and/or a mutually acceptable modification to this Plan of
         Merger within the 30-day period set forth in Section 6.10.1 (Mutual
         Agreement), or any extension thereof, and the condition or issue is
         not one for which it can be determined to a reasonable degree of
         certainty that the risk and expense to which Old Kent and its
         subsidiaries would be subject as an owner or operator of the property
         involved can be quantified and limited to an immaterial amount;
         provided, that Old Kent gives FNBC





                                      -66-

<PAGE>   74
         written notice of its intent to terminate this Plan of Merger pursuant
         to this Section 9.2.10 (Environmental Conditions) within the 30-day
         period set forth in Section 6.10.1 (Mutual Agreement), or any
         extension thereof.

                 9.2.11  Pooling Qualification.  At any time after Arthur
         Andersen & Co. shall have advised Old Kent that the Merger is unlikely
         to qualify for treatment as a pooling of interests for accounting
         purposes.

         9.3   FNBC's Rights to Terminate.  This Plan of Merger may be
terminated and the Merger abandoned by the Board of Directors, or a duly
authorized committee thereof, of FNBC under any of the following circumstances:

                 9.3.1  Breach of Warranty.  One or more of the representations
         and warranties made by Old Kent in this Plan of Merger shall have been
         discovered to be or to have become untrue and the cumulative effect of
         all such untrue representations and warranties is material to the
         business, income, or financial condition of Old Kent and its
         subsidiaries on a consolidated basis.

                 9.3.2  Breach of Covenant.  Old Kent shall have committed one
         or more breaches of any provision of this Plan of Merger which would
         in the aggregate be material; provided, that, if such breach or
         breaches can be cured, FNBC shall have given Old Kent specific notice
         of the breach or breaches in writing and Old Kent shall have not cured
         such breach or breaches to the reasonable satisfaction of FNBC within
         30 days of receipt of such notice.

                 9.3.3  Upset Date.  The Merger has not yet become effective on
         or before July 31, 1995.

                 9.3.4  Injunction.  A final unappealable injunction or other
         judgment shall have been issued by a court of competent jurisdiction
         restraining or prohibiting consummation of the Merger.

                 9.3.5  No Stockholder Approval.  The stockholders of FNBC have
         failed to adopt this Plan of Merger at an annual or special meeting,
         or adjournments thereof, called and held for that purpose, or that
         purpose and other purposes, at which the holders of not less than 70
         percent of the outstanding shares of FNBC Common Stock are present in
         person or represented by proxy, and such meeting has been finally
         adjourned.

                 9.3.6  No Regulatory Approval.  The Federal Reserve Board or
         its delegate shall have refused to approve the Merger; provided, that
         Old Kent shall have first had the opportunity to initiate and fully
         pursue its rights to appeal from, or seek judicial review of, any such
         refusal.  In the event of such appeal or review, and if such appeal





                                      -67-

<PAGE>   75
         or review results in a substantial affirmance of such refusal, then
         for purposes of this Section 9.3.6 such refusal shall be deemed not to
         have been made until the termination of such appeal or review.

                 9.3.7  Adverse Change.  There has occurred any change from
         that which existed on December 31, 1993, in the financial condition of
         Old Kent which is materially adverse to the business, income, or
         financial condition of Old Kent and its subsidiaries on a consolidated
         basis.

                 9.3.8  Old Kent Disclosure Statement.  The cumulative effect
         of any exceptions to Old Kent's representations and warranties or any
         other information set forth in the Old Kent Disclosure Statement shall
         be materially adverse to the business, financial condition, or income
         of Old Kent and its subsidiaries on a consolidated basis; provided
         that FNBC notifies Old Kent of such abandonment and termination not
         later than the last to occur of (i) 21 business days after FNBC
         receives the Old Kent Disclosure Statement, and (ii) 30 business days
         after the date of the execution of this Plan of Merger.


                                   ARTICLE X

                              AMENDMENT AND WAIVER

         10.1   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 FNBC, or by the respective officers thereunto duly authorized, at any
time prior to the Effective Time of the Merger.

         10.2   Waiver.  Any of the terms or conditions of this Plan of Merger
may be waived at any time by whichever of the parties is, or the shareholders
or stockholders (as the case may be) of which are, entitled to the benefit
thereof, by action taken by the board of directors of such party, or a duly
authorized committee thereof.  The failure of any party at any time or times to
require performance of any provision hereof shall in no manner affect such
party's right at a later time to enforce the same.  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.

         10.3   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 will be inadequate and not
susceptible of computation because of





                                      -68-

<PAGE>   76
the unique nature of FNBC, FNBC's Subsidiaries and the Merger.  Therefore, the
parties each agree that a federal 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.


                                   ARTICLE XI

                                 MISCELLANEOUS

         11.1   Termination Fee.  In recognition of the efforts, expenses,
other opportunities foregone by Old Kent while pursuing the Merger, and
unascertainable losses that may be incurred by Old Kent in the event that the
Merger is not consummated, and in recognition of Old Kent's potential role in
attracting the interest of Unaffiliated Persons (as defined below), the parties
agree that Old Kent shall, subject to the terms and conditions set forth in
this Section 11.1 (Termination Fee), be entitled to receive the Termination Fee
(as defined below) in the event of a Business Combination by an Unaffiliated
Person.  For the purposes of this Plan of Merger, an "UNAFFILIATED PERSON"
shall mean any individual, corporation, partnership, entity, group, or "person"
as defined in Section 13(d)(3) of the Securities Exchange Act and the
regulations issued thereunder, other than Old Kent, Old Kent's subsidiaries and
affiliates, and their respective directors, officers, employees,
representatives, and agents.  FNBC and Old Kent agree that the Termination Fee

                 11.1.1  Definitions.  For purposes of this Plan of Merger:

                          (a)  "Acquisition Price."  The "ACQUISITION PRICE"
                 per share of FNBC Common Stock shall mean (i) in the event of
                 a merger or consolidation, the market value per share of
                 consideration to be received by holders of FNBC Common Stock
                 in the transaction, determined as of the effective time of
                 such transaction; (ii) in the event of a tender offer, the
                 price per share paid to holders of FNBC Common Stock at the
                 conclusion of such offer; (iii) in the event of an exchange
                 offer or share exchange, the market value per share received
                 by holders of FNBC Common Stock in the transaction; or (iv) in
                 the event of any other form of Business Combination, the
                 average price per share at which FNBC Common Stock was
                 acquired by the party making the Business Combination between
                 the date of this Plan of Merger and the date on which the
                 Termination Fee is paid.

                          (b)  "Termination Fee."  The "TERMINATION FEE" shall
                 be the greater of (i) $1,500,000, or (ii) an amount which is
                 equal to 15 percent of the excess, if any, of the Acquisition
                 Price per share of FNBC Common Stock over the

<PAGE>   77
                 Purchase Price Per Share (as defined in Section 2.1.1),
                 multiplied by the number of shares of FNBC Common Stock
                 outstanding immediately prior to the Business Combination.

                 11.1.2  Rights to the Termination Fee.  Old Kent shall be paid
         the Termination Fee in the manner provided in Section 11.1.3 (Manner
         of Payment) if, while this Plan of Merger is in effect (i) any
         Unaffiliated Person directly or indirectly, or acting through one or
         more intermediaries, acquires Control (calculated using 25 percent) of
         FNBC, or its successor by merger or consolidation, or acquires 25
         percent or more of the consolidated assets of FNBC and FNBC's
         Subsidiaries; or (ii) FNBC solicits, invites, negotiates, or enters
         into an agreement with an Unaffiliated Person to acquire such Control
         or such assets, or either FNBC or an Unaffiliated Person publicly
         announces an intention to do so, and within one year of the date of
         such solicitation, invitation, negotiation, agreement or announcement
         (whether or nor this Plan of Merger is then in effect) the
         Unaffiliated Person acquires such Control or such assets.

                 11.1.3  Manner of Payment.  The Termination Fee shall be paid
         to Old Kent by wire transfer or by cashier's check of immediately
         available funds.  Old Kent shall be paid the Termination Fee:

                          (a)  In the event of a merger, consolidation, or
                 share exchange, at or after the consummation of the
                 transaction upon Old Kent's written demand; or

                          (b)  In any other case, upon termination of this Plan
                 of Merger, after Old Kent becomes entitled to the Termination
                 Fee.

                 11.1.4  Failure of a Condition Precedent.  Old Kent shall not
         be entitled to receive the Termination Fee if:

                          (b)  This Plan of Merger is terminated and the Merger

                 its part), or 8.6 (Registration Statement) (provided, however,

                 Provisions); or

                          (e)  This Plan of Merger is terminated and the Merger

         continue.

                 11.2.2  Liability.  Neither Old Kent nor FNBC shall incur any

         but not both.

     effects of convertible debt, where applicable, which includes elimination
     of any related after-tax interest expense.  The adjustments are made using
     the "if converted" method.

  - Number of shares in each category are adjusted to give effect to the 5%
     stock dividends in 1994 and 1993, and the 4-for-3 stock split in 1993.
