     3. NOTES EVIDENCING BORROWING.

        (a)  The Loans shall be evidenced by the following promissory notes:

                                       2


   3



     (i) a Line of Credit Note in the principal amount of TWENTY SIX MILLION
AND 00/100 DOLLARS ($26,000,000) (the "Line of Credit Note"), in the form of
Exhibit A hereto; and

     (ii) a Revolving Note in the principal amount of FIVE HUNDRED THOUSAND and
00/100 DOLLARS ($500,000) (the "Revolving Note"), in the form of Exhibit B
hereto (the Revolving Note and the Line of Credit Note are each referred to
individually as the "Note" and collectively as the "Notes").

Without in any way limiting the terms or conditions of the Notes:

     (b) Interest on both Notes shall be payable the earlier of quarterly or at
the end of a LIBOR Interest Period (as defined below), in arrears, commencing
on January 1, 1997 and continuing on the first day of each April, July, October
and January thereafter, with a final payment of all outstanding amounts due
under the Notes, including, but not limited to principal, interest and any
amounts owing under Subsection 10(k) of this Agreement, if not sooner paid, on
August 2, 1997.

     The amounts outstanding from time to time under the Line of Credit Note
shall bear interest calculated on the actual number of days elapsed on the
basis of a 360 day year, at a rate equal, at the Borrower's option of:

     (i)  the London Inter-Bank Offered Rate ("LIBOR") plus 125 basis
          points;

     (ii) the Prime Rate; or

     (iii) the fixed rate of 150 basis points in excess of the rate of
           treasury bills with the same maturity as the remaining term of the
           Line of Credit Note (the "Fixed Rate"; whichever rate is so selected
           or applicable to a Note from time to time, the "Interest Rate").

     The amounts outstanding from time to time under the Revolving Note shall
bear interest calculated on the actual number of days elapsed on the basis of a
360 day year at the Prime Rate.

     For purposes of this Agreement, the term "Prime Rate" shall mean the
floating prime rate in effect from time to time as set by the Bank, and
referred to by the Bank as its Prime Rate.  The Borrower acknowledges that the
Prime Rate is not necessarily the Bank's lowest or most favorable rate of
interest at any one time.  The effective date of any change in the Prime Rate
shall for purposes hereof be the date the rate change is publicly announced by
the Bank.

     LIBOR borrowings hereunder shall be for a period of one, two, three, six
or twelve months (each an "Interest Period").  Payments of LIBOR borrowings
shall be permitted only at the conclusion of an Interest Period.

     The Bank's determination of LIBOR as provided above shall be conclusive,
absent manifest error.  Furthermore, if the Bank determines, in good faith
(which determination shall be conclusive, absent manifest error), prior to the
commencement of any Interest Period that (a) U.S. dollar deposits of sufficient
amount and maturity for funding any LIBOR Loan are not available to the Bank in
the London Interbank Eurodollar market in the ordinary course of business, or
(b) by reason of circumstances affecting the London Interbank Eurodollar
market, adequate and fair means do not exist

                                       3


   4


for ascertaining the rate of interest to be applicable to the relevant LIBOR
Loan, the Bank shall promptly notify the Borrower and such LIBOR Loan shall be
immediately due and payable on the last banking day of the then existing
Interest Period, without further demand, presentment, protest or notice of any
kind, all of which are hereby waived by the Borrower.

     If, after the date hereof, the introduction of, or any change in any
applicable law, treaty, rule, regulation or guideline or in the interpretation
or administration thereof by any governmental authority or any central bank or
other fiscal, monetary or other authority having jurisdiction over the Bank or
its lending office (a "Regulatory Change"), shall, in the opinion of counsel to
the Bank, makes it unlawful for the Bank to make or maintain any LIBOR Loan
evidenced hereby, then the Bank shall promptly notify the Borrower and such
LIBOR Loan shall be immediately due and payable on the last banking day of the
then existing Interest Period or on such earlier date as required by law, all
without further demand, presentment, protest or notice of any kind, all of
which are hereby waived by the Borrower.

     If, for any reason, any LIBOR Loan is paid prior to the last banking day
of its then-current Interest Period, the Borrower agrees to indemnify the Bank
against any loss (including any loss on redeployment of the funds repaid), cost
or expense incurred by the Bank as a result of such prepayment.

     If any Regulatory Change (whether or not having the force of law) shall
(a) impose, modify or deem applicable any assessment, reserve, special deposit
or similar requirement against assets held by, or deposits in or for the
account of or loans by, or any other acquisition of funds or disbursements by,
the Bank; (b) subject the Bank or any LIBOR Loan to any tax, duty, charge,
stamp tax or fee or change the basis of taxation of payments to the Bank of
principal or interest due from the Borrower to the Bank hereunder (other than a
change in the taxation of the overall net income of the Bank); or (c) impose on
the Bank any other condition regarding such LIBOR Loan or the Bank's funding
thereof, and the Bank shall determine (which determination shall be conclusive,
absent manifest error) that the result of the foregoing is to increase the cost
to the Bank of making or maintaining such LIBOR Loan or to reduce the amount of
principal or interest received by the bank hereunder, then the Borrower shall
pay to the Bank, on demand, such additional amounts as the Bank shall, from
time to time, determine are sufficient to compensate and indemnify the Bank for
such increased cost or reduced amount.

     Each request by Borrower for a LIBOR Loan must be received by Bank no
later than 11:00 a.m. Chicago, Illinois time, on the day which is two days
prior to the day it is to be funded.  Requests for all other Loans must be
received by Bank no later than 11:00 a.m. Chicago, Illinois time, on the same
day it is to be funded.

         (c) No amount of principal repaid under the Line of Credit Note may be
borrowed again.  One principal payment in the amount of $10,000,000 shall be
due and payable under the Line of Credit Note on or before November 1, 1996.

         (d) Any amount of principal or interest on the Notes which is not paid
when due, whether at stated maturity, by acceleration or otherwise shall bear
interest payable on demand at an interest rate equal at all times to two
percent (2%) above the Interest Rate.

         (e) If any payment to be made by the Borrower hereunder shall become 
due on a Saturday, Sunday or Bank holiday under the laws of the State
of Illinois, such payment shall be made

                                       4

   5


on the next succeeding business day and such extension of time shall be
included in computing any interest in respect of such payment.

     4. PRINCIPAL PREPAYMENTS.

     Prepayments of principal amounts of Prime Rate Loans are permitted without
premium or penalty at any time, and shall be applied to the next succeeding
principal payment due. Prepayments of principal amounts of LIBOR Loans shall be
subject to Section 3(b), above.

     The Borrower may prepay the principal balance of Fixed Rate Loans, in
whole, subject to the following conditions:

     (a)  Not less than thirty (30) days prior to the date upon which the
Borrower desires to make such prepayment, the Borrower shall deliver to the
Bank written notice of its intention to prepay, which notice shall be
irrevocable and state the prepayment amount and the prepayment date (the
"Prepayment Date");

     (b) The Borrower shall pay to the Bank, concurrently with such prepayment,
a prepayment premium (the "Prepayment Premium") equal to the greater of (1) the
Yield Amount (as hereinafter defined) or (2) the Fixed Amount (as hereinafter
defined); and

     (c) The Borrower shall pay to the Bank all accrued and unpaid interest on
such Fixed Rate Loan through the date of such prepayment on the principal
balance being prepaid.

     The Borrower shall, in addition to the outstanding principal balance,
accrued interest and other sums due hereunder, pay the amount representing the
Prepayment Premium.  For purposes hereof, the "Fixed Amount" shall mean one
percent (1.00%) of the amount prepaid and the "Yield Amount" shall be the
amount calculated as follows:

          (A) There shall first be determined, as of the Prepayment Date,
     the amount, if any, by which the Fixed Rate exceeds the yield to
     maturity percentage (the "Current Yield") for the United States
     Treasury Note closest in maturity to the maturity of such Fixed Rate
     Loan (the "Treasury Note") as published in The Wall Street Journal on
     the fifth business day preceding the Prepayment Date.  If publication
     of (1) The Wall Street Journal or (2) the Current Yield of the Treasury
     Note in The Wall Street Journal is discontinued, the Bank, in its sole
     discretion, shall designate another daily financial or governmental
     publication of national circulation to be used to determine the Current
     Yield;
     
          (B) The difference calculated pursuant to clause (A) above shall
     be multiplied by the outstanding principal balance of the Fixed Rate
     Loan as of the Prepayment Date;
     
          (C) The product calculated pursuant to clause (B) above shall be
     multiplied by the quotient, rounded to the nearest one-hundredth of one
     percent, obtained by dividing (1) the number of days from and including
     the Prepayment Date to and including the maturity of the Fixed Rate
     Loan, by (2) 365; and
     
                                    5



   6




          (D) The sum calculated pursuant to clause (C) above shall be
     discounted at the annual rate of the Current Yield to the present value
     thereof as of the Prepayment Date, on the assumption that said sum
     would be received in equal monthly installments on each monthly
     anniversary of the Prepayment Date prior to the maturity date of the
     Fixed Rate Loan, with the final such installment to be deemed received
     on the maturity date of the Fixed Loan; provided, that the Borrower
     shall not be entitled in any event to a credit against, or a reduction
     of, the indebtedness being prepaid if the Current Yield exceeds the
     Fixed Rate or for any other reason.

     5. REPRESENTATIONS AND WARRANTIES.

     To induce the Bank to make the Loans provided for herein, the Borrower
represents and warrants as follows:

        (a) The Borrower: (i) is a corporation duly organized and validly 
existing and in good standing under the laws of the State of Delaware; (ii) is
duly qualified as a foreign corporation and in good standing in all states in
which it is doing business except where the failure to so qualify would not have
a material adverse effect on the Borrower or its business; and (iii) has all
requisite power and authority, corporate or otherwise, to own, operate and lease
its properties and to carry on its business as now being conducted.  Each of the
Subsidiaries is an Illinois banking corporation, and has all requisite power and
authority, corporate or otherwise, to own, operate and lease its property and to
carry on its business as now being conducted.  The Borrower and each Subsidiary
have made payment of all franchise and similar taxes in all of the respective
jurisdictions in which they are incorporated or qualified, so far as such taxes
are due and payable at the date of the Agreement, except for any such taxes the
validity of which is being contested in good faith and for which proper reserves
have been set aside on the books of the Borrower or the Subsidiaries, as the
case may be.

        (b) The proceeds of the Line of Credit Loan shall be used to acquire the
Country Shares and to consummate the merger with Prairie and upon acquisition
of the Country Shares, the Borrower shall be the owner of 100% of the issued
and outstanding capital stock of Country.  Attached hereto as Exhibit C is a
true, correct and complete list of the owners of the shares of capital stock of
the Subsidiaries.

        (c) The Country Shares have been duly authorized, legally and validly
issued, are fully paid and nonassessable, and are owned by the Borrower free
and clear of all pledges, liens, security interests, charges or encumbrances,
except, upon consummation of the transactions contemplated herein, for the
security interest granted by the Borrower to the Bank.  There are, as of the
date hereof, no outstanding options, rights or warrants obligating the Borrower
or the Subsidiaries to issue, deliver or sell, or cause to be issued, delivered
or sold, additional shares of the capital stock of the Subsidiaries or
obligating the Borrower or the Subsidiaries to grant, extend or enter into any
such agreement or commitment.

        (d) The financial statements of:

        (i) the Borrower, all of which have heretofore been furnished to the 
Bank, have been prepared in accordance with generally accepted
accounting principles consistently applied ("GAAP") and maintained by the
Borrower throughout the periods involved, and fairly present the financial

                                       6
   7


condition of the Borrower individually and on a consolidated basis at such
dates  specified therein and the results of its operations for the periods then
ended; and

     (ii) each Subsidiary, all of which have heretofore been furnished to the
Bank, to the best knowledge of the Borrower have been prepared in accordance

and fairly present the financial condition of such Subsidiary at such dates
specified therein and the results of its operation for the periods then
entered.

     (e) To the best knowledge of the Borrower, since the latest date of the
financial statements referred to in Section 5(d) above, there have been no
material changes in the assets, liabilities, or condition, financial or
otherwise, of the Borrower or the Subsidiaries other than changes arising from
transactions in the ordinary course of business, and none of such changes has
been materially adverse, whether in the ordinary course of business or
otherwise.  To the best knowledge of the Borrower, neither the business nor the
properties of the Borrower nor any Subsidiary have been materially and
adversely affected in any way, including, without limitation, as a result of
any fire, explosion, accident, strike, lockout, labor disputes, food, drought,
embargo, imposition of governmental restrictions, confiscation by a
governmental agency or acts of God.

     (f) There are no actions, suits, proceedings or written agreements
pending, or to the best of the knowledge of the Borrower threatened or
proposed, against the Borrower or, to the best knowledge of the Borrower, any
Subsidiary at law or in equity or before or by any federal, state, municipal,
or other governmental department, commission, board, or other administrative
agency, domestic or foreign, of a material nature; and neither of the Borrower
nor, to the best knowledge of the Borrower, any Subsidiary is in default with
respect to any order, writ, injunction, or decree of, or any written agreement
with, any court, commission, board or agency, domestic or foreign.

     (g) all tax returns and reports of the Borrower and, to the best knowledge
of the Borrower, each Subsidiary, required by law to be filed have been duly
filed, and all taxes, assessments, fees and other governmental charges upon the
Borrower and each Subsidiary or upon any of their properties or assets which
are due and payable have been paid, and the Borrower knows of no additional
assessment of a material nature against the Borrower or either Subsidiary for
taxes, or except as disclosed on the financial statements referred to in
Section 5(d) above, of any basis for any such additional assessment.

     (h) The Borrower's primary business is that of a bank holding company, and
all necessary regulatory approvals have been obtained for it to conduct its
business.

     (i) The deposit accounts of the Subsidiaries which are banks or savings
and loan entities are insured by the Federal Deposit Insurance Corporation
("FDIC").

     (j) None of the Pledged Security constitutes margin stock, as defined in
Regulation U of the Board of Governors of the Federal Reserve System ("FRS").

     The foregoing representations and warranties shall survive the making of
this Agreement, and execution and delivery of the Notes and the Pledge
Agreements, and shall be deemed to be continuing representations and warranties
until such time as the Borrower has satisfied all of its

                                       7


   8


obligations to the Bank, including, but not limited to the obligation to pay in
full all principal, interest and other amounts in accordance with the terms of
this Agreement or the Notes.

any such property to be subject to such mortgages or other liens, or mortgages
or other liens existing on any such property at the time of acquisition, or
extensions, renewals, or replacements of any of the foregoing for the same or a
lesser amount, provided that no such mortgage or other liens shall extend to or

of the consolidated capital of the Borrower or any Subsidiary, as the case may
be;

        (vii) liens existing on the date hereof as shown on their financial

     The Borrower agrees that until the Borrower satisfies all of its
obligations to the Bank, including, but not limited to its obligations to pay
in full all principal, interest and other amounts in accordance with the terms

     (c) maintain such capital as is necessary to cause the Borrower to have

requirements or conditions that the FRS has or may impose on the Borrower;

     (d) as of June 30, 1996 maintain such capital as is necessary to cause

retained earning accounts reduced by the amount of any goodwill;

     (f) cause the ratio of nonperforming loans to the primary capital of each
Subsidiary to be not more than twenty five percent (25%) at all times.  For

and lease losses and "nonperforming loans" shall mean the sum of all
non-accrual loans and loans on which any payment is ninety (90) or more days
past due;

governmental charges imposed upon the Borrower or the Subsidiaries or upon the
income, profits, or property of the Borrower or the Subsidiaries and all claims
for labor, material or supplies which, if unpaid, might by law become a lien or
charge upon the property of the Borrower or the Subsidiaries.  Neither the
Borrower nor any Subsidiary shall be required to pay any such tax, assessment,
charge or claim, so long as the validity thereof shall be contested in good
faith by appropriate proceedings, and reserves therefor shall be maintained on
the books of the Borrower or the Subsidiaries as are deemed reasonably adequate
by the Bank;

        (j) maintain bonds and insurance and cause the Subsidiaries to maintain
bonds and insurance with responsible and reputable insurance companies or

bonds and insurance as may be reasonably required by the Bank;

        (k) permit and cause the Subsidiaries to permit the Bank through its

and

        (l) provide and cause the Subsidiaries promptly to provide the Bank with
such other information concerning the business, operations, financial condition
and regulatory status of the Borrower and the Subsidiaries as the Bank may from
time to time reasonably request.

commenced by or against the Borrower or any Subsidiary under any bankruptcy,
reorganization, arrangement, insolvency, readjustment of debt, dissolution or
liquidation law or statute of the federal government or any state government
and if such proceedings are instituted against the Borrower, the Borrower by
any action or failure to act indicates its approval of, consent  to our

payable, without any presentment, demand, protest or other notice of any kind,
all of which are hereby expressly waived by the Borrower, anything contained
herein or in the Notes or the Pledge Agreements to the contrary
notwithstanding, and may, also without limitation, appropriate and apply toward
the payment of the Notes any indebtedness of the Bank to the Borrower however
created or arising, and may, also without limitation exercise any and all
rights in and to the collateral security referred to in Section 8 above and
under the Pledge Agreements.  There shall be no obligation to liquidate any
collateral pledge hereunder in any order or with any priority or to exercise
any remedy available to the Bank in any order.

     10. MISCELLANEOUS.

        (a) No failure or delay on the part of the Bank in exercising any right,
power or remedy hereunder shall operate as a waiver thereof.  No single or
partial exercise of any such right, power or remedy shall preclude any other or
further exercise thereof or the exercise of any other right, power or remedy
hereunder.  The remedies herein provided are cumulative and not exclusive of
any remedies provided by law.  Time is of the essence in the performance of the
covenants, agreements and obligations of the Borrower and the Subsidiaries.

and supersedes all prior agreements between the Bank and the Borrower with

demand on the Borrower in any case shall entitle the Borrower to any other or
further notice or demand in similar or other circumstances.

with any stamp or other taxes shall apply only to those taxes which arise
during the term of this Agreement or any extension hereof.  Any of the
foregoing amounts incurred by Bank and not paid by the Borrower upon demand
shall bear interest from the date incurred at the Prime Rate plus two percent
