Reasons for the              In considering the affiliation with ONB, the Board
Affiliation                  of Directors of Carmi collected and evaluated a 
                             variety of economic, financial and market
                             information regarding ONB and its affiliates, their
                             respective businesses and ONB's reputation and
                             future prospects. In the opinion of the Board of
                             Directors of Carmi, favorable factors included

                             management, the compatibility of its markets to
                             those of Carmi and the attractiveness of ONB's
                             offer from a financial perspective. Consideration

                             trading market. In addition, the Board considered
                             the opinion of Prairie Capital Services, Inc.
                             ("Prairie Capital"), the financial advisor to
                             Carmi, indicating that the consideration to be

                             against the Agreement at the Special Meeting or
                             give written notice to the officer presiding at the

                             foregoing request. In the event that holders of
                             greater than 10% of the outstanding shares of Carmi
                             Common Stock become entitled, by exercise of
                             dissenters' rights or otherwise, to receive cash
                             instead of ONB Common Stock, the Affiliation will
                             not qualify as a pooling-of-interests transaction

                             certain statutory procedures. See "PROPOSED
                             AFFILIATION -- Rights of Dissenting Shareholders of
                             Carmi" and Appendices B and C to this Proxy
                             Statement.

                             stock. See "COMPARISON OF COMMON STOCK".

                           THE NATIONAL BANK OF CARMI

                          TO BE HELD ON MAY 30, 1996

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

                              GENERAL INFORMATION

     This Proxy Statement is furnished to the shareholders of Carmi in
connection with the solicitation by the Board of Directors of proxies for use at
the Special Meeting of Shareholders to be held on May 30, 1996, at the main
office of Carmi, located at 116 West Main Street, Carmi, Illinois 62821. This
Proxy Statement is first being mailed to shareholders of Carmi on May 1, 1996.

     The purposes of the Special Meeting of Shareholders are to (1) consider and
vote upon the Agreement, under the terms of which Carmi will affiliate with ONB
through a merger of Carmi into an interim national bank subsidiary of ONB, and
each outstanding share of the Carmi Common Stock will be converted into the
right to receive 3.885 shares of ONB Common Stock, subject to adjustment, if
any, in accordance with the terms of the Agreement, and (2) transact such other
business which may properly be presented at the Special Meeting or any
adjournment thereof. See "PROPOSED AFFILIATION - Exchange of Carmi Common
Stock".

     The affirmative vote of the holders of at least two-thirds of the
outstanding shares of Carmi Common Stock is required for approval of the
Agreement. Only holders of Carmi Common Stock of record at the close of business
on May 1, 1996 ("Record Date") are entitled to notice of, and to vote at, the
Special Meeting. There were 100,000 shares of Carmi Common Stock outstanding on
the Record Date, which were held of record by approximately 101 shareholders.
For each matter to be voted on at the Special Meeting, each share of Carmi
Common Stock is entitled to one vote.

     The cost of soliciting proxies will be borne by Carmi. In addition to use
of the mails, proxies may be solicited personally or by telephone or telegraph
by directors, officers and certain employees of Carmi, who will not be specially
compensated for such soliciting.

     The shares represented by proxies properly signed and returned will be
voted at the Special Meeting as instructed by the shareholders of Carmi giving
the proxies. In the absence of specific instructions to the contrary, proxies
will be voted FOR approval of the Agreement described in this Proxy Statement
and in accordance with the recommendation of the Board of Directors of Carmi
with respect to any other matter which may properly be presented at the Special
Meeting. See "PROPOSED AFFILIATION -- Rights of Dissenting Shareholders of
Carmi". Any shareholder giving a proxy has the right to revoke it at any time
before it is exercised. Therefore, execution of

                                      -1-
<PAGE>
 

a proxy will not affect a shareholder's right to vote in person if he or she
attends the Special Meeting. Revocation may be made by a later dated proxy
delivered to Carmi, by written notice received by the Cashier of Carmi prior to
the Special Meeting, or by written notice delivered to the Cashier of Carmi at
the Special Meeting. To be effective, any revocation must be received before the
proxy is exercised. Requests for proxy recordation should be mailed to William
Kent Fulkerson, Cashier, The National Bank of Carmi, 116 West Main Street,
Carmi, Illinois 62821.

                             PROPOSED AFFILIATION

     At the Special Meeting, the shareholders of Carmi will consider and vote
upon the Agreement, certain features of which are summarized below. The
following summary of certain aspects of the Agreement does not purport to be a
complete description of the terms and conditions of the Agreement and is
qualified in its entirety by reference to the Agreement, which is attached to
this Proxy Statement as Appendix A and is incorporated herein by reference.

DESCRIPTION OF THE AFFILIATION

     Under the terms of the Agreement, Carmi will affiliate with ONB through a
statutory merger of Carmi into Merger Bank under the laws of the United States
of America. Merger Bank will be the surviving banking institution in the Merger
and, at the effective time of the Merger, the separate corporate existence of
Carmi will cease. Merger Bank will continue as a wholly-owned subsidiary of ONB
and its name following consummation of the Merger will be "The National Bank of
Carmi".

     As of December 31, 1995, Carmi had consolidated assets of $66.1 million,
consolidated deposits of $56.2 million, consolidated shareholders' equity of
$8.0 million and consolidated net income for the year then ended of $463,800.
Based upon the pro forma financial information included elsewhere in this Proxy
Statement and assuming that the Affiliation had been consummated on December 31,
1995, Carmi represented as of such date 1.37% of the consolidated assets of ONB,
1.41% of its consolidated deposits, 1.88% of its consolidated shareholders'
equity and, for the year then ended, 0.90% of its consolidated net income. See
"PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION".

BACKGROUND OF AND REASONS FOR THE AFFILIATION

     Until recently, Indiana and Illinois banking laws prohibited banks located
in Indiana and Illinois from expanding outside of their home counties. The
changes since the prohibition was lifted have been swift, first permitting in-
state acquisitions by bank holding companies, then permitting regional
interstate acquisitions, and currently permitting virtual nationwide expansion
opportunities. These developments stimulated aggressive acquisition activity
among financial institutions located in Indiana and neighboring states,
resulting in the entry of large bank holding companies into virtually every
attractive market in the midwestern United States. Moreover, developments and
deregulation in the financial services industry generally have led to further
increases in competition for bank services. Compounded by the significant
increase in bank regulatory burdens over the past decade, these competitive
factors have created an environment in which it is increasingly difficult for
community banks such as Carmi to achieve the economies of scale necessary to
compete effectively.

     In response to these competitive and regulatory factors and after
evaluation of financial, economic, legal and market considerations, the Board of
Directors of Carmi approved the Affiliation as being in the best interests of
Carmi and its shareholders. Discussions concerning

                                      -2-
<PAGE>
 

whether to remain independent or whether to pursue an affiliation with another
financial institution were a frequent topic among the directors of Carmi.
Discussions regarding a possible affiliation between ONB and Carmi began in
June, 1995, and continued intermittently through the following months. The Board
of Directors of Carmi met on a number of different occasions to consider a
merger proposal from ONB. On November 20, 1995, the parties executed a non-
binding written letter of intent. After a business investigation by ONB and
Carmi of each other, the parties executed a definitive merger agreement on March
15, 1996. In determining to pursue the Affiliation, the Board of Directors of
Carmi specifically considered financial, managerial and other information
regarding ONB and its affiliates. In particular, the Board of Directors of Carmi
evaluated ONB's and Carmi's respective businesses, financial condition,
reputation and future prospects. The earnings history and stock performance of
ONB were carefully reviewed and discussed with Prairie Capital with a view
toward the investment potential for shareholders of Carmi.

     Among other items considered in this evaluation were the prospects of Carmi
and ONB, as separate institutions and as combined; the compatibility of ONB's
affiliate bank's markets to that of Carmi's market; the anticipated tax-free
nature of the Affiliation to the shareholders of Carmi receiving solely ONB
Common Stock in exchange for their shares of Carmi Common Stock; the possibility
of increased liquidity through ownership of ONB Common Stock as compared to
Carmi Common Stock because ONB Common Stock is traded in the over-the-counter
market and share prices are reported on the Nasdaq National Market System; the
timeliness of a merger given the state of the economy and the stock markets as
well as anticipated trends in both; regulatory requirements; relevant price
information involving recent comparable bank acquisitions which occurred in the
midwest United States; and an analysis of alternatives to affiliating with ONB,
including other potential acquirors. In addition, the Board considered the
opinion of Prairie Capital indicating that the consideration to be received by
Carmi's shareholders under the Agreement is fair from a financial perspective.

     The Board of Directors of Carmi also considered the impact of the
Affiliation on Carmi's customers and employees and the communities served by
Carmi. ONB's historical practice of retaining employees of acquired institutions
with competitive salary and benefit programs was considered, as was the
opportunity for training, education, growth and advancement of Carmi's employees
within ONB or one of its affiliates. The Board of Directors of Carmi examined
ONB's continuing commitment to the communities served by institutions previously
acquired by ONB. Further, from the standpoint of Carmi's customers, it was
anticipated that more products and services would become available because of
ONB's greater resources.

     Based upon the foregoing factors, the Board of Directors of Carmi concluded
that it was advantageous to affiliate with ONB. The importance of the various
factors relative to one another cannot be precisely determined or stated.

OPINION OF FINANCIAL ADVISOR TO CARMI

     Prairie Capital has delivered its written opinion to the Board of Directors
of Carmi that as of April 9, 1996, the consideration provided for in the
Agreement is fair, from a financial point of view, to the holders of Carmi
Common Stock.

     Prairie Capital was engaged by Carmi's Board of Directors to advise it as
to the fairness of the consideration, from a financial perspective, to be paid
by ONB to Carmi shareholders under the Agreement. Prairie Capital is an
investment banking firm based in Evanston, Illinois. As a part

                                      -3-
<PAGE>
 

of its investment banking business, Prairie Capital is regularly engaged in
reviewing the fairness of bank acquisitions from a financial perspective and in
the valuation of banks and other business and their securities in connection
with mergers, acquisitions, estate settlements and other transactions. Prairie
Capital was selected by the Board of Directors of Carmi based upon Prairie
Capital's familiarity with the market for stock of Illinois financial
institutions and their knowledge of the banking industry generally.

     The full text of Prairie Capital's fairness opinion ("Opinion"), dated
April 9, 1996, which sets forth the assumptions made, matters considered and
limits on the review undertaken, is attached as Appendix D to this Proxy
Statement. Carmi shareholders are urged to read the Opinion in its entirety.
Prairie Capital has not made or sought to obtain appraisals of Carmi's assets in
rendering the Opinion. Neither Carmi nor ONB placed any limitations upon Prairie
Capital with respect to the investigations made or procedures followed by
Prairie Capital in rendering the Opinion. The Opinion is directed solely to the
Board of Directors of Carmi and concerns only the consideration provided for in
the Agreement and does not constitute a recommendation to any of Carmi's
shareholders as to how such shareholder should vote at the Special Meeting. The
summary of the Opinion set forth in this Proxy Statement is qualified in its
entirely by reference to the full text of the Opinion included in Appendix D
hereto.

     Prairie Capital has provided the following disclosure to Carmi for
inclusion in this Proxy Statement:

     Fairness Opinion   The Carmi Board entered into an agreement with Prairie
Capital on October 26, 1995 to render an opinion as to the fairness, from a
financial point of view, of the consideration to be received by the holders of
Carmi Common Stock.

     There were no limitations placed on the scope of Prairie Capital's
activities in obtaining and reviewing data, holding discussions with Carmi and
ONB managements and performing such analyses as it deemed necessary in order to
render a fairness opinion to the Carmi Board. Prior to the proposed Merger,
Prairie Capital has had no financial advisory or other business relationship
with Carmi or ONB in the last two years. Prairie Capital did provide some
analyses that were used by Carmi in negotiating the Merger consideration.

     On January 25, 1996, Prairie Capital provided a written presentation to the
Carmi Board of Directors to the effect that the consideration to be received
from ONB in the Merger is fair, from a financial point of view, to the Carmi
shareholders. Prairie Capital delivered a written opinion to the Board on April
9, 1996.

     In arriving at its opinion dated April 9, 1996, Prairie Capital had
discussions with certain officers of Carmi and ONB and reviewed and analyzed,
among other data: (i) the annual reports to shareholders of Carmi for the years
ended December 31, 1990 through 1994 with financial statements unaudited in 1990
through 1992 and audited in 1993 and 1994 and unaudited interim financial
statements as of and for the eleven months ended November 30, 1995; (ii) the
annual reports and 10-K SEC filings for ONB for the years ended December 31,
1990 through 1994, the quarterly reports and 10-Q filings for the first three
quarters of 1995, five proxy statement/prospectuses on transactions completed by
ONB in 1995 and a news release dated January 29, 1996 with the unaudited
financial statements for the year ended December 31, 1995; (iii) a copy of the
Agreement of Affiliation and Merger; (iv) draft copies of the Proxy
Statement/Prospectus; (v) publicly-available information on the common stock
prices and financial performance of selected Midwestern bank holding companies
and ONB; (vi) the

                                      -4-
<PAGE>
 

announced terms of selected small and medium-sized Midwestern bank merger and
acquisition transactions from September, 1994 through December, 1995; (vii)
other information Prairie Capital deemed relevant; and (viii) other internal
financial and operating information which was provided to Prairie Capital by
Carmi and ONB.

     Prairie Capital also took into account its assessment of general economic,
market and financial conditions and its experience in other transactions, as
well as its experience in securities valuation and its knowledge of the banking
industry generally. Prairie Capital's opinion was necessarily based upon
conditions as they existed and could be evaluated on the date thereof and
information made available to Prairie Capital through the date thereof.

     Prairie Capital assumed and relied upon, without independent verification,
the accuracy and completeness of the information reviewed by it for the purposes
of its opinion. Prairie Capital did not make any independent valuation or
appraisal of the assets or liabilities of Carmi and ONB, nor was Prairie Capital
furnished with any such appraisals. Prairie Capital assumed, without independent
verification, that the aggregate allowances and reserves for loan and lease
losses of Carmi and ONB were adequate to cover such losses.

     Prairie Capital performed a variety of financial analyses which are
summarized below. The summary of such analyses set forth herein does not purport
to be a complete description of such analyses. Prairie Capital believes that its
analyses and the summary set forth herein must be considered as a whole and that
selecting portions of such analyses and the factors considered therein, without
considering all factors and analyses, could create an incomplete view of the
analyses and the processes behind Prairie Capital's opinion. The preparation of
a fairness opinion is a complex process involving subjective judgments and is
not necessarily susceptible to partial analysis or summary description. In its
analyses, Prairie Capital made numerous assumptions with respect to industry
performance, business and economic conditions and other matters, many of which
are beyond the control of Carmi and ONB. Any estimates and projections contained
in Prairie Capital's analyses are not necessarily indicative of future results,
which may be significantly more or less favorable than such estimates and
projections. Estimates and projections of values of companies do not purport to
be appraisals or necessarily reflect the prices at which companies or their
securities actually may be sold. No company or transaction utilized in Prairie
Capital's analyses was identical to Carmi, ONB or the Merger. Accordingly, such
analyses are not based solely on arithmetic calculations; rather, they involve
complex considerations and judgments concerning differences in financial and
operating characteristics of the relevant companies, the timing of the relevant
transactions and prospective buyer interest, as well as other factors that could
affect the public trading values of the company or companies to which they are
being compared. None of the analyses performed by Prairie Capital was assigned a
greater significance by Prairie Capital than any other.

     The analyses performed by Prairie Capital related to rendering its opinions
to the Board of Directors of Carmi are summarized below:

     (i)    Summary of Merger Terms.  Under the Agreement, each share of Carmi
            Common Stock will be converted into 3.885 shares of ONB common
            stock. Should the average of the closing prices of ONB Common Stock,
            as quoted on the Nasdaq National Market System, be more that 10%
            above or below $32.50 per share ($35.75 above and $29.25 below),
            then the Exchange Ratio would be adjusted so as to permit no more
            than a 10% deviation in the $32.50 value. Carmi shareholders will
            
                                      -5-
<PAGE>
 

            receive as cash dividends the equivalent of the net income of Carmi
            from January 1, 1996 to closing.
 
     (ii)   Review of Carmi and ONB. Carmi's total assets have increased from
            $59.7 million at 1990 yearend to $66.7 million at 1994 yearend and
            $66.6 million as of November 30, 1995. The increase in assets was
            more than accounted for by the acquisition of The First National
            Bank of Crossville ($13.5 million in assets) on December 17, 1993.
            Net income excluding securities gains or losses increased from
            $535,000 in 1989 to $569,000 in 1990, $828,000 in 1992 and $830,000
            in 1993 before declining to $750,000 in 1994 and $718,000 for the
            twelve months ended November 30, 1995. The recent decline in
            earnings reflects a lower net interest margin, no offsetting
            increase in earning assets and higher noninterest expenses including
            goodwill amortization from the Crossville acquisition. The return on
            average assets increased from 1.06% in 1990 to 1.51% in 1992 and
            declined to 1.07% in 1994 and 1.04% for the twelve months ended
            November 30, 1995. The return on average shareholders' equity ranged
            from 7.98% in 1990 to 11.03% in 1992 and 8.80% in 1994 and 8.54% for
            the twelve months ended November 30, 1995. Carmi has maintained a
            very high capital ratio equal to 12.47% of assets at November 30,
            1995 and 10.70% tangible capital to assets. (The capital accounts
            were adjusted for the anticipated payment of dividends.) Reflecting
            its high capital ratio and lack of growth, Carmi has paid out a high
            proportion of earnings as dividends on the common stock.

            For the five years ended 1994, ONB achieved annual earnings growth
            of 9.1% and cash dividend growth of 7.6% compared to asset growth of
            3.9%. Profitability has improved as the return on average assets has
            increased from 0.93% in 1990 to 1.14% in 1994. Return on average
            shareholders' equity has increased from 11.28% in 1990 to 12.65% in
            1994 while the equity to assets ratio has gone from 8.39% to 9.02%
            over the same period. For the full year 1995, ONB reported fully
            diluted earnings per share of $2.04 compared to $1.78 the prior year
            for a 14.6% increase. The per share figures have been adjusted for a
            5% stock dividend payable on February 20, 1996. ONB management is
            estimating earnings per share of $2.25 to $2.30 in 1996 and has a
            goal for 1998 of about $2.85 per share. The current annual dividend
            rate of $0.92 compares to $0.88 paid in 1995.

     (iii)  ONB Common Stock.  Prairie Capital compared the common stocks and
            financial performance of ten bank holding companies (collectively,
            "BHCs") with ONB's. The BHCs are based in Indiana, Illinois,
            Kentucky and Ohio and have total assets of between $1 billion and $5
            billion.

            It was noted that ONB's common stock was selling at 16.4 times the
            latest twelve months earnings, 15.7 times the estimated 1995
            earnings, 197.4% of stated book value and 204.5% of tangible book
            value. The comparison group had a median price/earnings ratio based
            on latest twelve months earnings of 13.8 times earnings, 13.3 times
            earnings based on estimated 1995 earnings, a median price/stated
            book value ratio of 173.4% and a price/tangible book value of
            190.8%.

            As to financial performance, ONB had ratios based on the latest
            twelve months results virtually equal to the median of the
            comparison group with return on average assets of 1.16%, return on
            average stockholders' equity of 12.88%, an equity to assets ratio of
            8.93% and a tangible equity to assets ratio of 8.64%. ONB's
            
                                      -6-
<PAGE>
 

            percentage of nonperforming assets to total assets at 0.34% was
            lower that the group median while ONB's loan loss reserves as a
            percentage of nonperforming assets at 268.63% was higher than the
            group median. ONB's market capitalization for its common stock is
            larger than that of any of the BHCs in the group.

     (iv)   Analysis of Recent Comparable Bank Mergers and Acquisition
            Transactions. Prairie Capital reviewed bank merger and acquisition
            transactions in the Midwest and selected 24 transactions that have
            been announced since September, 1994. The selling banks/bank holding
            companies were based in Indiana, Illinois and Kentucky and in all
            but one transaction, the sellers had total assets under $200
            million.

            The average and median price/earnings ratios for the 24 transactions
            were 15.5 times earnings and 14.5 times earnings. Based on a value
            of the proposed Merger of about $12.7 million, the price/earnings
            ratio for the proposed Merger would be 18.1 times earnings for the
            twelve months ended November 30, 1995.

            The price/book value ratios for the proposed Merger are 154.2% of
            stated book value and 181.3% of tangible book value. These ratios
            are below the average and median ratios of 180.4% and 168.4% for
            stated book value and close to or above the ratios for tangible book
            value of 183.3% and 170.8% for the 24 transactions. Carmi has stated
            equity capital equal to 12.47% of assets compared to an average of
            9.37% and a median of 8.83% for the selling banks/bank holding
            companies in the 24 reviewed transactions. Prairie Capital excluded
            from Carmi's capital any capital in excess of 7% of tangible capital
            to assets (or 8.78% of stated capital to assets) in calculating the
            price to stated and tangible book value ratios. After this
            adjustment, Carmi's purchase price in relation to book value would
            be 179.2% of stated book value and 229.3% of tangible book value.

     (v)    Present Value Analysis.  Prairie Capital prepared two projections of
            Carmi's results for five years. In the first projection, Prairie
            Capital assumed that Carmi's net income would remain flat at
            $750,000 over the five year period and all of the earnings would be
            paid out to stockholders each year as cash dividends. The cash
            dividends were discounted back to present value at 10%, 12% and 14%
            discount rates. Also, it was assumed that Carmi would be valued at
            15 times fifth year earnings in a sale transaction and that value
            was discounted back to present value at the same discount rates. The
            present values ranged from a low of $84.13 per Carmi share to a high
            of $98.29 and compared to $126.72 per Carmi share in value of ONB
            common stock in the proposed Merger.

            In the second projection, Prairie Capital made the following
            assumptions, among others, about Carmi: earning asset growth would
            be 2% annually; the net interest margin would rise from 4.00%
            currently to 4.10% the first and second years to 4.20% in the third
            and fourth years and 4.30% in the fifth year; other income as a
            percent of average assets would be 0.37%; noninterest expenses as a
            percent of average assets would be 2.50%, down from about 2.60%
            currently and the effective tax rate would be 25%. Again, Prairie
            Capital assumed that the projected earnings would be all paid out to
            stockholders as cash dividends on the common stock and that Carmi
            would be sold at the end of the fifth year at 15 times fifth year
            earnings. The projected dividends and fifth year sale value were
            discounted back to present value at 10%, 12% and 14% discount rates.
            The present values ranged from a low

                                      -7-
<PAGE>
 

            of $102.31 per Carmi share to a high of $119.71 compared to $126.72
            per Carmi share in value of ONB common stock in the proposed Merger.

     (vi)   Comparison of Projected Financial Results and Values for ONB and for
            Carmi on a stand alone basis. Prairie Capital prepared an analysis
            that compared the dividends and fifth year values that were
            projected for Carmi in the "Present Value Analysis" with projected
            dividends and fifth year value that Carmi stockholders might receive
            as ONB shareholders. The projections for ONB assumed earnings per
            share of $2.44 the first year (before the recent 5% stock dividend)
            and 8% earnings growth in the second through fifth years, projected
            cash dividends on the ONB common stock equal to 40% of earnings, and
            a range of fifth year values of ONB common stock equal to 12 times,
            13 times, 14 times and 15 times fifth year earnings. The projected
            combination of cash dividends and fifth year values for Carmi on a
            stand alone basis were $150.00 and $184.11 per Carmi share. The
            projected combination of cash dividends and fifth year values that
            Carmi stockholders might realize from the ONB shares to be received
            from the proposed Merger ranged from a low of $168.60 per Carmi
            share to a high of $205.44. Prairie Capital noted that ONB common
            stock has much better marketability and liquidity than Carmi common
            stock.

     Prairie Capital, as part of its investment banking business, is engaged in
the valuation of businesses, including banks and thrifts, and securities in
connection with mergers and acquisitions, public and private financings, thrift
stock conversions and valuations for estate, corporate and other purposes. Carmi
selected Prairie Capital on the basis of the reputations of its principals and
their experience in evaluating financial institutions such as Carmi and ONB and
in evaluating transactions such as the Merger.

     For its services to Carmi in connection with the Merger, Prairie received
an aggregate cash fee of $9,600 and was reimbursed for all of its out-of-pocket
expenses relating to the Merger. In addition, Carmi has agreed to indemnify
Prairie Capital against certain liabilities, including liabilities which may
arise under the federal and state securities laws.

     THE FULL TEXT OF PRAIRIE CAPITAL'S WRITTEN OPINION DATED APRIL 9, 1996,
WHICH SETS FOR THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITS ON ITS
REVIEW, IS ATTACHED HERETO AS APPENDIX D. HOLDERS OF SHARES OF CARMI COMMON
STOCK ARE URGED TO AND SHOULD READ SUCH OPINION IN ITS ENTIRETY.

RECOMMENDATION OF THE BOARD OF DIRECTORS

     THE BOARD OF DIRECTORS OF CARMI HAS CAREFULLY CONSIDERED AND UNANIMOUSLY
APPROVED THE AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF CARMI
APPROVE THE AGREEMENT.

EXCHANGE OF CARMI COMMON STOCK

     Under the terms of the Agreement, shareholders of record of Carmi upon
consummation of the Affiliation will be entitled to receive 3.885 shares of ONB
Common Stock for each share of Carmi Common Stock ("Exchange Ratio"), subject to
adjustment, if any, for stock splits, stock dividends or any similar
recapitalization

                                      -8-
<PAGE>
 

of ONB and for changes in the price of ONB Common Stock as reported by the
Nasdaq National Market System below $29.25 or above $35.75, all as described in
the Agreement attached hereto as Appendix A. 

     If, between the date of the Agreement and the effective time of the
Affiliation, the record date occurs for the distribution or issuance by ONB of a
stock dividend with respect to the shares of ONB Common Stock, or the
combination, subdivision, reclassification or split of the issued and
outstanding shares of ONB Common Stock, such that the number of issued and
outstanding shares of ONB Common Stock is increased or decreased, then the
Exchange Ratio will be adjusted so that Carmi shareholders will receive, in the
aggregate, such number of shares of ONB Common Stock representing the same
percentage of outstanding shares of ONB Common Stock at the effective time of
the Affiliation as would have been represented by the number of shares such
shareholders would have received if any of the foregoing actions had not
occurred.

    If the Average Price Per Share (as defined in the Agreement) of ONB Common
Stock is greater than $35.75 or less than $29.25, then the Exchange Ratio shall
be adjusted prior to the Effective Time. The adjustment would be applied in the
following manner: (i) if the Average Price Per Share of ONB Common Stock exceeds
$35.75, then the Exchange Ratio would be adjusted such that each share of Carmi
Common Stock would be converted into the number of shares of ONB Common Stock
resulting from the following formula: $126.72 / ($32.50 + (Average Price Per
Share - $35.75)); (ii) if the Average Price Per Share of ONB Common Stock is
less than $29.25, then the Exchange Ratio shall be adjusted such that each share
of Carmi Common Stock shall be converted into the number of shares of ONB Common
Stock resulting from the following formula: $126.72 / ($32.50 - ($29.25 - 
Average Price Per Share)); and (iii) if the Average Price Per Share of ONB
Common Stock is not less than $29.25 nor more than $35.75, then there shall be
no adjustment to the Exchange Ratio.

     In the event of a stock split, stock dividend or other recapitalization,
the Exchange Ratio will be adjusted so that Carmi shareholders will receive, in
the aggregate, the same percentage of the outstanding shares of ONB Common Stock
they would have received if the recapitalization had not occurred.

     As of April 25, 1996, the closing price of ONB Common Stock was $34.00 per
share, as reported by the Nasdaq National Market System. If the Affiliation had
been consummated on that date, the number of shares of ONB Common Stock
exchanged in the Affiliation would have been 388,500, with an aggregate value of
approximately $13,209,000.

     No fractional shares of ONB Common Stock will be issued to shareholders of
Carmi in connection with the Affiliation. Each shareholder of Carmi who
otherwise would be entitled to a fractional interest in a share of ONB Common
Stock as a result of the application of the Exchange Ratio will be paid a cash
amount equal to such fractional interest multiplied by the average of the per
share closing prices of ONB Common Stock as reported on the Nasdaq National
Market System for the first five (5) business days on which shares of ONB Common
Stock are traded within the ten (10) calendar days immediately preceding the
effective time of the Affiliation.

     After the effective time of the Affiliation, stock certificates previously
representing Carmi Common Stock will represent only the right to receive shares
of ONB Common Stock and cash for any fractional shares. Following the effective
time of the Affiliation and prior to the surrender by holders of Carmi of their
stock certificates to ONB in exchange for ONB Common Stock, such holders will
not be entitled to receive payment of dividends or other distributions declared
on shares of ONB Common Stock. Upon the subsequent exchange of such
certificates, however, any accumulated dividends or other distributions
previously declared and withheld on the shares of ONB Common Stock will be paid,
without interest. At the effective time of the Affiliation, the stock transfer
books of Carmi will be closed and no transfers of shares of Carmi Common Stock
will thereafter be made. If, after the effective time of the Affiliation,
certificates representing shares of Carmi Common Stock are presented for
registration or transfer, they will be canceled and exchanged for shares of ONB
Common Stock or cash, as the case may be.

     Distribution of stock certificates representing shares of ONB Common Stock
and any cash payment for fractional shares (without interest) will be made,
after the effective time of the Affiliation, to each former shareholder of Carmi
within twenty (20) business days following the shareholder's delivery to ONB of
his or her certificate(s) representing shares of Carmi Common Stock.
Instructions as to delivery of stock certificates of Carmi to ONB will be sent
to each shareholder of Carmi within twenty (20) days following the effective
time of the Affiliation.

DISSENTERS' RIGHTS

     In accordance with Title 12, Section 215a of the United States Code, a copy
of which is attached hereto as Appendix B, shareholders of Carmi have the right
to dissent from the Merger and to receive the value of their Carmi Common Stock.
In order to perfect dissenters' rights, a shareholder must take the following
steps: (i) either vote against the Agreement at the Special Meeting or give
written notice to the officer presiding at the Special Meeting prior to or at
the Special Meeting that the shareholder dissents from approval of the
Agreement; (ii) submit a written request for payment of the value of his or her
shares of Carmi Common Stock to Merger Bank at any time before thirty (30) days
after the consummation of the Merger; and (iii) surrender to Merger Bank the
certificates representing his or her shares of Carmi Common Stock at the time of
making the foregoing request. ONB will mail notice of the date of consummation
of the Affiliation to each person listed as a shareholder of Carmi on such date.

     The "value" of a dissenting shareholder's shares of Carmi Common Stock
(determined as of the effective date of the Merger) will be determined in
accordance with the following procedure, which is contained in Title 12, Section
215a of the United States Code. Three appraisers will be appointed, one to be
elected by the vote of two-thirds of the shareholders of Carmi who have
perfected their right to dissent as set forth above, one to be selected by the
Board of Directors of Merger Bank, and the third to be selected by the other two
appraisers. The valuation agreed upon by any two of the three appraisers shall
govern. If the value of Carmi Common Stock established by the appraisers is not
satisfactory to any dissenting shareholder, such dissenting shareholder may,
within five (5) days after being notified of the appraised value of the shares,
appeal to the United States of America Office of the Comptroller of the Currency
("OCC"), which shall cause a reappraisal to be made, and such reappraisal will
be final and binding upon the dissenting shareholder so appealing. The value of
the shares as determined by the OCC shall be promptly paid by Merger Bank to the
dissenting shareholder. All expenses of the OCC in making an appraisal or a
reappraisal will be paid by Merger Bank.

     If, within ninety (90) days of the date of consummation of the Merger, one
or more of the appraisers is not selected or the appraisers fail to determine
the value of the shares of Carmi Common Stock, then the OCC will upon written
request of any dissenting shareholder cause an appraisal to be performed, which
will be binding upon all parties. The value of the shares of Carmi Common Stock
determined by the appraisers or the OCC must be promptly paid by Merger Bank to
the dissenting shareholders. The expenses of the OCC in making the reappraisal
or the appraisal, as the case may be, must be paid by Merger Bank.

     The shares of ONB Common Stock which would have been delivered to such
dissenting shareholders had they not dissented to the Merger will be sold at an
advertised public auction. Merger Bank may purchase any of such shares at such
public auction for the purpose of reselling such shares within thirty (30) days.
If the shares are sold at public auction at a price greater than the amount paid
by Merger Bank to the dissenting shareholders, the excess in such sale price
will be paid to such dissenting shareholders.

     The OCC also has issued Banking Circular 259, dated March 5, 1992, relating
to its valuation methods used for appraisals in connection with mergers such as
the Merger. A copy of such Circular is attached hereto as Appendix C.

     THE FOREGOING SUMMARY OF THE RIGHTS OF DISSENTING SHAREHOLDERS ADDRESSES
ALL MATERIAL FEATURES OF THE APPLICABLE DISSENTERS' RIGHTS STATUTES, UNDER THE
LAWS OF THE UNITED STATES OF AMERICA BUT DOES NOT PURPORT TO BE COMPLETE AND IS
QUALIFIED IN ITS ENTIRETY BY THE STATUTORY PROVISIONS ATTACHED HERETO AS
APPENDIX B. THE DISSENTERS' RIGHTS RELATING TO SHAREHOLDERS OF CARMI SHOULD BE
READ IN CONJUNCTION WITH THE OCC'S CIRCULAR ATTACHED HERETO AS APPENDIX C.

     A SHAREHOLDER'S FAILURE TO COMPLY WITH THE STATUTORY REQUIREMENTS FOR
EXERCISING DISSENTERS' RIGHTS WILL RESULT IN A LOSS OF SUCH RIGHTS, AND
SHAREHOLDERS WHO MAY WISH TO EXERCISE DISSENTERS' RIGHTS SHOULD CONSIDER SEEKING
LEGAL COUNSEL.

RESALE OF ONB COMMON STOCK BY AFFILIATES OF CARMI

     No restrictions on the sale or transfer of the shares of ONB Common Stock
issued pursuant to the Affiliation will be imposed solely as a result of the
Affiliation, other than restrictions on the transfer of such shares issued to
any shareholder of Carmi who may be deemed to be an "affiliate" of Carmi for
purposes of Rule 145 under the Securities Act.  Directors, executive officers
and 10% shareholders are generally deemed to be affiliates for purposes of Rule
145.

     The Agreement provides that Carmi will provide ONB with a list identifying
each affiliate of Carmi.  The Agreement also requires that each affiliate of
Carmi deliver to ONB, on or prior to the date of the Agreement, a written
agreement to the effect that such affiliate (i) will not sell, pledge, transfer,
dispose of or otherwise reduce the affiliate's market risk with respect to the
shares of Carmi Common Stock directly or indirectly owned or held by such person
during the thirty (30) day period prior to the effective time, and (ii) will not
sell, pledge, transfer or otherwise dispose of or reduce the affiliate's market
risk with respect to the shares of ONB Common Stock to be received by such
person pursuant to the Agreement (A) until such time as financial results
covering at least thirty (30) days of combined operations of Carmi and ONB have
been published within the meaning of Section 201.01 of the Commission's
Codification of Financial Reporting Policies and (B) unless done pursuant to an
effective registration statement under the Securities Act or pursuant to Rule
145 or another exemption from the registration requirements under the Securities
Act.  The certificates representing ONB Common Stock issued to affiliates of
Carmi in the Affiliation may contain a legend indicating these resale
restrictions.

     This is only a general statement of certain restrictions regarding the sale
or transfer of the shares of ONB Common Stock to be issued in the Affiliation.
Therefore, those shareholders of Carmi who may be deemed to be affiliates of
Carmi should consult with their legal counsel regarding the resale restrictions
that may apply to them.

CONDITIONS TO CONSUMMATION

     Consummation of the Affiliation is conditioned upon, among other items, (1)
approval of the Agreement by the affirmative vote of the holders of at least
two-thirds of the outstanding shares of Carmi Common Stock, (2) receipt by ONB
and Carmi of all applicable regulatory approvals required for the Affiliation,
(3) receipt of an opinion of counsel with respect to certain federal income tax
matters, (4) receipt by ONB of certain undertakings from affiliates of Carmi,
(5) receipt by ONB and Carmi of certain officers' certificates and other legal
opinions, (6) the accuracy at the effective time of the Affiliation of
representations and warranties contained in the Agreement, and (7) the
fulfillment of certain covenants set forth in the Agreement.  The conditions to
consummation of the Affiliation, which are more fully enumerated in the
Agreement, are requirements subject to unilateral waiver by the party entitled
to the benefit of such conditions, as set forth in the Agreement.  See "PROPOSED
AFFILIATION -- Resale of ONB Common Stock by Carmi Affiliates", "-- Regulatory
Approvals", "FEDERAL INCOME TAX CONSEQUENCES" and Appendix A.

TERMINATION

     The Agreement may be terminated before consummation of the Affiliation by
either ONB or Carmi (as specified in the Agreement) if, among other reasons:
(1) there has been a misrepresentation or a breach of any warranty set forth in
the Agreement by Carmi or ONB which has had or could be expected to have a
material adverse effect on the financial condition, results 

                                      -11-
<PAGE>
 
of operations, business, assets or capitalization of Carmi or ONB, (2) ONB or
Carmi has breached or failed to comply with any covenant set forth in the
Agreement, (3) consummation of the Affiliation has become inadvisable or
impracticable due to the commencement or threat of any claim, litigation or
proceeding against ONB or Carmi, or any subsidiary of ONB relating to the
Agreement or which is likely to have a material adverse effect on the financial
condition, results of operations, business, assets or capitalization of ONB or
Carmi, (4) there has been a material adverse change in the financial condition,
results of operations, business, assets or capitalization of ONB or Carmi as of
the effective time of the Affiliation as compared to that in existence as of
December 31, 1995 other than changes resulting primarily by reason of changes in
banking laws or regulations (or interpretations thereof), changes in the general
level of interest rates or changes in economic, financial or market conditions
affecting the banking industry generally in Carmi's market or the regions in
which ONB and its affiliates operate, (5) ONB cannot utilize the pooling-of-
interests method of accounting for the Affiliation and such failure to qualify
is the result of actions taken or omitted to be taken by Carmi or its directors,
officers or shareholders other than as permitted by the Agreement, or (6)
consummation of the Affiliation has not occurred by November 30, 1996. Upon
termination for any of these reasons, the Agreement will be of no further force
or effect. See Appendix A to this Proxy Statement.

RESTRICTIONS AFFECTING CARMI

     The Agreement contains a number of restrictions regarding the conduct of
business of Carmi pending consummation of the Affiliation.  Among other items,
Carmi may not, without the prior written consent of ONB:  (1) change its capital
stock accounts, (2) distribute or pay any dividends, except that Carmi may pay a
quarterly cash dividend to its shareholders until consummation of the
Affiliation in an aggregate amount not to exceed Carmi's undivided profits from
December 31, 1995 through and including the effective time of the Affiliation;
provided, however, that if Carmi's shareholders become entitled to receive a
cash dividend from ONB for the calendar quarter during which the Affiliation is
consummated, then the aggregate cash dividends permitted to be paid by Carmi to
its shareholders will be reduced by the aggregate cash dividend for such quarter
receivable by Carmi's shareholders from ONB, and if the amount of such dividend
from ONB is not yet determinable, such amount will be calculated based upon the
per share amount of the last cash dividend paid by ONB to its shareholders, (3)
amend its Articles of Association or By-Laws, (4) carry on its business other
than substantially in the manner as conducted as of the date of the Agreement
and in the ordinary course of business, or (5) merge, combine or sell Carmi,
except under certain limited circumstances.  See Appendix A to this Proxy
Statement.

REGULATORY APPROVALS

     The Affiliation requires the prior approval of the Board of Governors of
the Federal Reserve System ("Federal Reserve") under the Bank Holding Company
Act of 1956, as amended ("BHC Act"), the OCC under the National Bank Act, as
amended, and the Illinois Commissioner of Banks and Trust Companies ("ICBT")
under the Illinois Bank Holding Company Act of 1957.  ONB has filed applications
with the Federal Reserve, the OCC and the ICBT for their prior approval of the
Affiliation.

     Approval of the Affiliation by the Federal Reserve, the OCC and the ICBT is
not to be interpreted as the opinion of these regulatory authorities that the
Affiliation is favorable to the shareholders of Carmi from a financial point of
view or that those regulatory authorities have considered the adequacy of the
terms of the Affiliation.  An approval by the Federal Reserve, the 

                                      -12-
<PAGE>
 
OCC or the ICBT in no way constitutes an endorsement or a recommendation of the
Affiliation by such regulatory authorities.

ACCOUNTING TREATMENT FOR THE AFFILIATION

     It is anticipated that the Affiliation will be accounted for as a "pooling-
of-interests" transaction.  Under this method of accounting, shareholders of ONB
and Carmi will be deemed to have combined their existing voting common stock
interests.  See "SUMMARY OF SELECTED FINANCIAL DATA" and "PRO FORMA CONDENSED
COMBINED FINANCIAL INFORMATION".

     In order for the Affiliation to qualify for pooling-of-interests accounting
treatment, among other items, 90% or more of the outstanding shares of Carmi
Common Stock must be exchanged for ONB Common Stock.  In the event the holders
representing more than 10% of the outstanding shares of Carmi Common Stock
become entitled by the exercise of dissenters' rights or otherwise to receive
cash instead of ONB Common Stock, the Affiliation would not qualify for pooling-
of-interests method of accounting and ONB would have the right to terminate the
Agreement.  See "PROPOSED AFFILIATION -- Rights of Dissenting Shareholders" and
"PROPOSED AFFILIATION -- Termination".

EFFECTIVE TIME

     The Affiliation will become effective at the close of business on the day
specified in the Articles of Merger of Carmi with and into Merger Bank as filed
with the OCC.  The effective time of the Affiliation will occur on the last
business day of the month following (1) the fulfillment of all conditions
precedent to the Affiliation set forth in the Agreement and (2) the expiration
of all waiting periods in connection with the bank regulatory applications filed
for approval of the Affiliation, unless otherwise mutually agreed to by ONB and
Carmi.

     ONB and Carmi currently anticipate that Affiliation will be consummated
during the second or third quarter of 1996.

MANAGEMENT, PERSONNEL AND OPERATIONS AFTER THE AFFILIATION

     Merger Bank will be the surviving banking institution in the Merger and,
upon consummation of the Merger, the separate corporate existence of Carmi will
cease.

     Upon consummation of the Affiliation, Merger Bank will continue as a
wholly-owned subsidiary of ONB, and the name of Merger Bank will be changed to
"The National Bank of Carmi".  The Board of Directors of Carmi serving at the
effective time of the Affiliation will serve as the Board of Directors of Merger
Bank after the effective time of the Affiliation.  Following the effective time
of the Affiliation, ONB, as the sole shareholder of Merger Bank, will have the
ability to elect the Board of Directors of Merger Bank.  The officers of Merger
Bank following consummation of the Affiliation will be the officers of Carmi
serving at the effective time of the Affiliation until the Board of Directors of
Merger Bank determines otherwise.

     Those persons who are full-time officers or employees of Carmi as of the
effective time of the Affiliation, provided that these persons continue as full-
time officers or employees of Merger Bank or any other subsidiary of ONB after
the effective time of the Affiliation, will receive substantially the same
employee benefits on substantially the same terms and conditions that ONB 

                                      -13-
<PAGE>
 
may offer to similarly situated officers and employees of its banking
subsidiaries from time to time. In addition, years of service of an employee of
Carmi prior to the effective time of the Affiliation will be credited to each
such employee for purposes of eligibility under ONB's employee welfare benefit
plans and for purposes of eligibility and vesting, but not for accrual or
contributions, under the ONB Employees' Retirement Plan ("ONB Pension Plan") and
the ONB Employees' Savings and Profit Sharing Plan ("ONB Profit Sharing Plan").

     Those officers and employees of Carmi who otherwise meet the eligibility
requirements of the ONB Pension Plan and the ONB Profit Sharing Plan, based upon
their age and years of service to Carmi, shall become participants thereunder on
the January 1st which coincides with or next follows the effective time of the
Affiliation.  Those officers and employees who do not meet the eligibility
requirements of the ONB Pension Plan or ONB Profit Sharing Plan on such date
shall become participants thereunder on the on the first "plan entry date" (as
defined in the ONB Pension Plan or ONB Profit Sharing Plan, as the case may be)
which coincides with or next follows the date on which such eligibility
requirements are satisfied.

     No full-time officer or employee of Carmi serving as of the effective time
of the Affiliation will be subject to any pre-existing condition exclusions
under any of ONB's welfare benefit plans if such officer, employee or individual
was covered by the corresponding Carmi welfare benefit plan for more than two
hundred seventy (270) days immediately preceding the effective time of the
Affiliation.

INTERESTS OF CERTAIN PERSONS IN THE AFFILIATION

     Carmi and James L. Whetstone, its President and Chief Executive Officer,
have entered into an employment agreement effective November 17, 1995 for a term
of three (3) years from such date, which term is automatically extended for one
(1) additional year unless terminated by either party as of the last day of the
then current three (3) year term.  Pursuant to the terms of the Agreement, ONB
has agreed to assume Mr. Whetstone's employment agreement.

     Under the Agreement, ONB has agreed to cause the Merger Bank and Insurance
Agency to assume and honor any obligations as provided for and permitted by
applicable federal and state law which Carmi and Insurance Agency had
immediately prior to the effective time of the Affiliation with respect to the
indemnification of each person who is a director or officer of Carmi or
Insurance Agency or was serving at the request of Carmi or Insurance Agency as a
director or officer of any domestic or foreign corporation, joint venture,
trust, employee benefit plan or other enterprise (collectively, the
"Indemnitees") arising out of Carmi's Articles of Association or By-Laws or
Insurance Agency's Certificate of Incorporation or By-Laws in effect at the
effective time of the Affiliation against any and all losses in connection with
or arising out of any claim which is based upon, arises out of or in any way
relates to any actual or alleged act or omission occurring at or prior to the
effective time of the Affiliation in the Indemnitee's capacity as a director or
officer (whether elected or appointed), of Carmi or Insurance Agency.
Indemnification of officers and directors of the Merger Bank and Insurance
Agency following the effective time of the Affiliation will be provided to the
same extent it is provided from time to time to other persons working in similar
capacities for ONB or its subsidiaries following the effective time of the
Affiliation.

     For a period of one (1) year after the effective time of the Affiliation,
ONB shall use all reasonable efforts to cause to be maintained in effect the
current policies of directors' and officers' liability insurance maintained by
Carmi (provided that ONB may substitute therefor policies of at least the same
coverage and amounts containing terms and conditions which are substantially no

                                      -14-
<PAGE>
 
less advantageous) with respect to claims arising from facts or events which
occurred before the effective time of the Affiliation.  Following the effective
time of the Affiliation, ONB will provide any Carmi employees who become
officers of ONB or any of its subsidiaries with the same directors' and
officers' liability insurance coverage that ONB provides to other similarly
situated directors and officers of ONB and its bank subsidiaries.

                        FEDERAL INCOME TAX CONSEQUENCES

     The following discussion summarizes certain federal income tax aspects of
the Affiliation.  This discussion does not purport to cover all federal income
tax consequences relating to the Affiliation and does not contain any
information with respect to state, local or other tax laws.

TAX OPINION

     ONB and Carmi have requested the law firm of Krieg DeVault Alexander &
Capehart to render an opinion that the Affiliation constitutes a tax-free
reorganization and, with respect to certain federal income tax consequences of
the Affiliation, substantially to the effect that the merger to be effected
pursuant to the Affiliation constitutes a tax-free reorganization under the
Internal Revenue Code of 1986, as amended ("Code") to each party thereto and to
the shareholders of Carmi, except with respect to cash received by Carmi's
shareholders (i) for fractional share interests of ONB Common Stock or (ii)
pursuant to the exercise of dissenters' rights.

     The opinion rendered by Krieg DeVault Alexander & Capehart will be based
upon the assumption of certain facts to be stated in the opinion, including,
among others, that there is no plan or intention by the shareholders of Carmi to
sell or dispose of their shares of ONB Common Stock received in the Merger or
sell or dispose of their shares of Carmi Common Stock prior to the effective
time of the Affiliation that would reduce their ownership of ONB Common Stock to
an aggregate value, as of the effective time of the Affiliation, of less than
fifty percent (50%) of the value of all of the formerly outstanding shares of
Carmi Common Stock as of the same date.  Under the Agreement, the obligations of
each of ONB and Carmi to consummate the Affiliation is conditioned upon the
receipt of an opinion of counsel substantially to the effect as set forth above.

TAX CONSEQUENCES TO ONB AND CARMI

     The merger of Carmi with and into Merger Bank constitutes a statutory
merger under applicable law.  Consequently, based  upon the assumption of
certain facts to be stated in the opinion, the merger of Carmi with and into
Merger Bank should constitute a tax-free reorganization.  As a result, ONB,
Merger Bank and Carmi will recognize neither gain nor loss as a result of the
Affiliation for federal income tax purposes.

TAX CONSEQUENCES TO CARMI SHAREHOLDERS

     A.   Carmi Shareholders Receiving Solely ONB Common Stock
          ----------------------------------------------------

     A Carmi shareholder who receives solely ONB Common Stock in exchange for
all of the shares of Carmi Common Stock actually owned by the shareholder will
not recognize any gain or loss upon such exchange for federal income tax
purposes.  See paragraph C. below for a discussion of the tax consequences of
the receipt of cash in lieu of fractional share interests of ONB Common Stock.

                                      -15-
<PAGE>
 
     B.   Dissenting Carmi Shareholders Receiving Solely Cash
          ---------------------------------------------------

     The transaction will result in income being recognized for federal income
tax purposes for Carmi shareholders who dissent to the Affiliation and receive
solely cash in exchange for their shares of Carmi Common Stock.  A shareholder
who receives solely cash for the shareholder's shares of Carmi Common Stock
pursuant to the Affiliation through the exercise of dissenters' rights and, as a
result of the surrender of all of the shareholder's shares of Carmi Common
Stock, owns no Carmi Common Stock either directly or through the constructive
ownership rules of Section 318 of the Code, would recognize capital gain or loss
(assuming that the Carmi Common Stock is held by such shareholder as a capital
asset) equal to the difference between the amount of the cash received and the
shareholder's tax basis of its shares of Carmi Common Stock.

     C.   Cash Received in Lieu of Fractional Shares
          ------------------------------------------

     A Carmi shareholder who receives cash in lieu of a fractional share
interest of ONB Common Stock will be treated as having received such fraction of
a share of ONB Common Stock and then as having received cash in redemption of
the fractional share interest, subject to the provisions of Section 302 of the
Code.

     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE HAS NOT BEEN VERIFIED
WITH THE INTERNAL REVENUE SERVICE, IS INCLUDED FOR GENERAL INFORMATION ONLY AND
IS BASED UPON THE FEDERAL INTERNAL REVENUE CODE AS IN EFFECT ON THE DATE OF THIS
PROXY STATEMENT WITHOUT CONSIDERATION OF ANY STATE LAWS OR THE PARTICULAR FACTS
OR CIRCUMSTANCES OF ANY SHAREHOLDER OF CARMI.  THE ABOVE DISCUSSION MAY NOT BE
APPLICABLE WITH RESPECT TO SHARES ACQUIRED PURSUANT TO THE EXERCISE OF STOCK
OPTIONS OR OTHERWISE RECEIVED AS COMPENSATION.  SHAREHOLDERS ARE URGED TO
CONSULT WITH THEIR TAX ADVISOR WITH RESPECT TO ALL TAX CONSEQUENCES OF THE
AFFILIATION TO THEM, INCLUDING THE EFFECT OF FEDERAL, STATE AND LOCAL TAX LAWS
AND ANY OTHER TAX CONSEQUENCES.

                           COMPARATIVE PER SHARE DATA

     There is no established public trading market for shares of Carmi Common
Stock and shares of Carmi Common Stock are traded in limited quantities in
private transactions.  Since there are no market makers for Carmi Common Stock
and no recognized exchanges on which shares of Carmi Common Stock are traded,
there is no published source of prices relating to transactions in Carmi Common
Stock.  Most trades occur as a result of private negotiations in isolated
transactions, with the result that management of Carmi Common Stock is not
directly informed of the number of trades or prices at which shares of Carmi
Common Stock are traded.

     The table below sets forth, for the periods indicated, the high and low
trade prices for shares of Carmi Common Stock, the number of shares traded and
the number of trades of Carmi Common Stock, based upon information received by
management of Carmi.  The last two trades of Carmi Common Stock, the terms of
which management of Carmi are aware, occurred on or about February 20, 1996 and
involved the sale of One Hundred Twenty-Five (125) shares each.  Management of
Carmi is unaware of the price of these trades.  As of the Record Date, there
were approximately 101 holders of Carmi Common Stock.

(1)  There can be no assurance as to the amount of future dividends that may
     be declared or paid on shares of ONB Common Stock since dividend policies
     are subject to the discretion of the Board of Directors of ONB, general
     business conditions and dividends paid to ONB by its affiliate banks.
     For certain restrictions on the payment of dividends on shares of ONB
     Common Stock, see "COMPARISON OF COMMON STOCK -- Dividend Rights".

(2)  The Agreement provides Carmi may make quarterly cash dividends to its
     shareholders until consummation of the Affiliation in an aggregate amount
     not to exceed Carmi's undivided profits from December 31, 1995, through
     and including the effective time of the Affiliation; provided, however,
     that if Carmi's shareholders become entitled to receive a cash dividend
     from ONB for the calendar quarter during which the Affiliation is
     consummated, then the 

                                      -18-
<PAGE>
 
     aggregate cash dividends permitted to be paid by Carmi to its shareholders
     will be reduced by the aggregate cash dividend for such quarter receivable
     by Carmi's shareholders from ONB, and if the amount of such dividend from
     ONB is not yet determinable, such amount will be calculated based upon the
     per share amount of the last cash dividend paid by ONB to its shareholders.

EXISTING AND PRO FORMA PER SHARE INFORMATION

     The following table sets forth certain historical, pro forma and
equivalent information.  The data is based on historical financial statements
and the pro forma financial information included on pages 21 through 26 and has
been restated to give effect to all stock dividends.  Equivalent per share data
is calculated by multiplying the pro forma ONB information by the Exchange Ratio
under the Agreement.

                              DESCRIPTION OF ONB
BUSINESS

     ONB is a multi-bank holding company with 24 affiliate banks located in the
tri-state area comprised of southwestern Indiana and neighboring portions of
Illinois and Kentucky. With total consolidated assets of $4.82 billion as of
December 31, 1995, ONB is the largest independent bank holding company
headquartered in the State of Indiana. Since 1985, ONB has acquired 34 financial
institutions, 10 of which were combined with existing affiliate banks, and has
increased its banking offices to 118. ONB anticipates that it will continue its
policy of geographic expansion through strategic affiliations with additional
commercial banks and thrifts. See "DESCRIPTION OF ONB -- Acquisition Policy and
Pending Affiliations".

     The principal activity of ONB is to own, manage and supervise its affiliate
banks and its non-bank subsidiaries, each of which is held by ONB as a separate
wholly-owned subsidiary. The primary source of ONB's revenue is dividends and
fees received from its subsidiaries. There are various legal limitations on the
extent to which the affiliate banks may finance, pay dividends to or otherwise
supply funds to ONB. See "REGULATORY CONSIDERATIONS" and "COMPARISON OF COMMON
STOCK -- Dividend Rights".

     ONB's affiliate banks engage in a wide range of commercial and consumer
banking activities and provide other services relating to the general banking
business. Set forth below is a list of ONB's affiliate banks by state.

            THE NATIONAL BANK OF CARMI MANAGEMENT'S DISCUSSION AND
           ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION

             FOR THE YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993

GENERAL

Carmi provides commercial banking services to individuals and businesses through
its two facilities in Carmi and Crossville, Illinois. The area served by Carmi
is primarily White County. Carmi competes with other commercial banks, savings
institutions and financial institutions for all types of deposits, loans and
other financial services.

COMPARISON OF OPERATING RESULTS FOR THE YEARS 1995, 1994 AND 1993

Net Interest Income.  Total interest income increased by $287,363 for 1995
compared to 1994 and by $547,794 for 1994 compared to 1993. The primary reason
for the increase was due to both increases in interest rates and volume. The
average yield on loans was 8.95%, 8.29% and 7.49%, for 1995, 1994 and 1993,
respectively. The average rate paid on interest-bearing deposits increased from
3.31% in 1993 to 3.53% in 1994 to 4.21% in 1995. The improved net interest rate
spread resulted in net interest income of $2,484,835, $2,527,442 and $2,178,477
for the years ended December 31, 1995, 1994 and 1993, respectively.

The changes in interest income and interest expense resulting from changes in
volume and changes in rates for the years ended December 31, 1995 and 1994 are
shown in the schedule captioned "Rate/Volume Analysis" included herein. The net
change in income on earning assets included the effect of taxable equivalent
adjustments using a marginal federal income tax rate of 34 percent for both
years.

Provision for Loan Losses.  During 1995, Carmi recorded a provision for loan
losses in the amount of $400,000 compared to $ 0 for 1994 and $86,000 for 1993.
The increase in the provision for loan losses for 1995 compared to 1994 was due
to management's evaluation of the adequacy of the allowance for loan losses
based on reviews of specific loans, which consider the financial condition of
the borrower and the fair market value of the collateral, as well as other risk
factors. Management's evaluation of the loan portfolio resulted in its decision
to increase the allowance for loan losses to a level of 2.25% of total loans
outstanding at December 31, 1995 compared to 1.08% and 1.33% at December 31,
1994 and 1993, respectively.

Non-Interest Income.  Carmi's principal source of non-interest income was
service charges on deposit accounts. Non-interest income totaled $264,868,
$213,884, and $181,503 for 1995, 1994 and 1993, respectively. The increase in
non-interest income for 1995 was due to less net investment securities losses of
$(3,002) for 1995 compared to $(38,344) for 1994 and $(4,327) in 1993 and
increases in service charges of $16,612 and $32,513 in 1995 and 1994,
respectively.

Non-Interest Expense.  Total non-interest expense was $1,763,045 in 1995
compared to $1,792,214 for 1994 and $1,375,474 for 1993. The decrease in non-
interest expenses for 1995 compared to 1994 was $29,169 with primarily all the
decrease due to a refund and rate decrease in FDIC insurance. FDIC insurance
decreased $65,222 for 1995 compared to 1994.

The increase in non-interest expense for 1994 compared to 1993 was caused by
several factors.

                                     -34-
<PAGE>
 

During 1994, salaries and employee benefits increased by $173,617 compared to
the prior year. This increase was due primarily to additional personnel
necessary to handle the acquisition of The First National Bank of Crossville.

Net occupancy expenses for 1994 increased by $50,655 compared to the prior year.
This increase was due primarily to increased cost in the operation of the
Crossville facility.

Amortization expense of $94,383.18 in 1994 resulted from the writeoff of
goodwill purchased in the acquisition of The First National Bank of Crossville
at the end of 1993.

Other operating expenses also increased during 1994 by $192,467 compared to the
prior year. This increase was a result of several factors including legal fees
increasing by $28,328 mainly due to the acquisition of the Crossville facility.
Other increases in 1994 over the prior year were FDIC insurance $19,201,
advertising $8,275, and $11,728 in supplies expense.

Income Tax Expense.  For 1995, Carmi has an unused net operating loss carryover
of $165,412 and an AMT credit carryover of $9,990. Carmi reported income tax
expense for the years 1995, 1994 and 1993 of $122,858, $237,009 and $114,331,
respectively.

Carmi adopted FAS Statement 109 as of January 1, 1993 and the effect of this
adoption is shown as a separate item on the 1993 income statement.

ASSET AND LIABILITY MANAGEMENT

The primary goal of asset/liability management is the coordinated effort to
manage both assets and liabilities to maximize the net interest income with an
acceptable level of liquidity and interest rate risk. Management is responsible
for implementing proper policies and strategies to achieve this goal.

Interest rate sensitivity refers to the effect of changing interest rates on net
interest income. Management's objective, as it relates to interest rate
sensitivity, is to maximize net interest income while limiting exposure to the
risk associated with the volatility of interest rates. A widely accepted method
of measuring this exposure is the ratio of rate-sensitive assets to rate-
sensitive liabilities. A financial instrument is said to be rate sensitive if it
matures or otherwise reprices within a given time frame, usually six months or
one year. Management combines the analysis of this ratio with interest rate and
balance sheet forecasts to establish appropriate strategies.

As of December 31, 1995, management believes it effectively managed interest
rate risk by maintaining a cumulative ratio of rate-sensitive assets to rate-
sensitive liabilities of 49.97%.

LIQUIDITY IN CAPITAL RESOURCES

Effective liquidity management insures that the cash flow requirements of
depositors and borrowers, as well as the operating cash needs of Carmi, are met.
Liquidity is provided by cash flow from operations and a number of other
sources, including the securities portfolio, short-term and overnight
investments and funds from deposits. Carmi also has the ability to obtain funds
through short-term borrowings on its Treasury Tax and Loan note option account,
and the Federal Reserve Bank under a season borrowing line of credit. Liquidity
management is both a daily and long-term function of business management. Excess
liquidity is generally invested in short-term investments, such as federal funds
sold and interest bearing deposits in other financial institutions.

                                     -35-
<PAGE>
 

Carmi adjusts its liquidity levels in order to meet funding needs for deposit
outflows and loan commitments. Carmi also adjusts liquidity as appropriate to
meet its asset/liability management objectives.

Risk-based capital standards were issued by banking regulatory authorities
during the first quarter of 1989. The standards call for minimum total capital
of 8 percent of risk-adjusted assets, as defined. At December 31, 1995, Carmi's
level of regulatory capital exceeded all applicable requirements at that date.
Management considers the present capital structure to be sufficient to support
on-going operations and normal growth.

ASSET QUALITY

Carmi has implemented a system to identify and monitor non-performing and
delinquent loans. To enhance loan monitoring and collection efforts, Carmi has
emphasized the accurate assessment of loss exposure and identification of such
loans in a timely manner.

Non-performing loans are defined as all loans which are accounted for on a
nonaccrual basis and loans 90 days or more past due and still accruing interest.
The accrual of interest is discontinued on a loan when it becomes 90 days past
due and is not in the process of collection or when management believes, after
considering economic conditions and collection efforts, that the borrower's
financial condition is such that collection of interest is doubtful. When loans
are placed on nonaccrual status, all unpaid accrued interest is written off and
while on nonaccrual status all future income is recorded only as cash payments
are received.

As of December 31, 1995, non-performing loans totaled approximately $101,200 or
 .29% of total loans, as compared to approximately $52,200 or .16% of total loans
at December 31, 1994.

The allowance for loan losses totaled approximately $775,000 or 2.28% of total
loans as of December 31, 1995 as compared to approximately $350,800 or 1.10% of
total loans as of December 31, 1994. In addition, as of December 31, 1995, the
allowance for loan losses equaled 765% of non-performing loans as compared to
672% as of December 31, 1994.

IMPACT OF INFLATION AND CHANGING PRICES

The financial statements and related data presented herein have been prepared in
accordance with generally accepted accounting principles, which require the
measurement of financial position and operating results in terms of historical
dollars without considering change in the relative purchasing power of money
over time due to inflation. The impact of inflation is reflected in the
increased cost of Carmi's operations. Unlike most industrial companies, nearly
all the assets and liabilities of Carmi are monetary. As a result, interest
rates have a greater impact on Carmi's performance than do the effects of
general levels of inflation. Interest rates do not necessarily move in the same
direction or to the same extent as the price of goods and services.

AVERAGE BALANCE SHEETS

The following table sets forth certain information relating to Carmi's average
balance sheet and reflects the average yield on interest earning assets and
average rates paid on interest bearing liabilities for the period indicated.
Such yields and rates are derived by dividing income or expense by the average
balance of assets or liabilities, respectively, for the periods presented.
Yields are calculated on a fully taxable equivalent basis using the marginal
federal income tax rate of 34%.

                           REGULATORY CONSIDERATIONS

BANK HOLDING COMPANY REGULATION

     ONB is a registered bank holding company and is subject to the regulations
of the Federal Reserve under the BHC Act. Bank holding companies are required to
file periodic reports with and are subject to periodic examination by the
Federal Reserve. The Federal Reserve has issued regulations under the BHC Act
requiring a bank holding company to serve as a source of financial and
managerial strength to its subsidiary banks. It is the policy of the Federal
Reserve that, pursuant to this requirement, a bank holding company should stand
ready to use its resources to provide adequate capital funds to its subsidiary
banks during periods of financial stress or adversity. Additionally, under the
Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA"), a bank
holding company is required to guarantee the compliance of any insured
depository institution subsidiary that may become "undercapitalized" (as defined
in the statute) with the terms of any capital restoration plan filed by such
subsidiary with its appropriate federal banking agency up to the lesser of (i)
an amount equal to 5% of the institution's total assets at the time the
institution became undercapitalized, or (ii) the amount that is necessary (or
would have been necessary) to bring the institution into compliance with all
applicable capital standards as of the time the institution fails to comply with
such capital restoration plan. Under the BHC Act, the Federal Reserve has the
authority to require a bank holding company to terminate any activity or
relinquish control of a nonbank subsidiary (other than a nonbank subsidiary of a
bank) upon the Federal Reserve's determination that such activity or control
constitutes a serious risk to the financial soundness and stability of any bank
subsidiary of the bank holding company.

     ONB is prohibited by the BHC Act from acquiring direct or indirect control
of more than 5% of the outstanding shares of any class of voting stock or
substantially all of the assets of any bank or savings association or merging or
consolidating with another bank holding company without prior approval of the
Federal Reserve. Additionally, ONB is prohibited by the BHC Act from engaging in
or from acquiring ownership or control of more than 5% of the outstanding shares
of any class of voting stock of any company engaged in a nonbanking business
unless such business is determined by the Federal Reserve to be so closely
related to banking as to be a proper incident thereto. The BHC Act does not
place territorial restrictions on the activities of such nonbanking-related
activities.

CAPITAL ADEQUACY GUIDELINES FOR BANK HOLDING COMPANIES

     Bank holding companies are required to comply with the Federal Reserve's
risk-based capital guidelines which require a minimum ratio of total capital to
risk-weighted assets (including certain off-balance sheet activities such as
standby letters of credit) of 8%. At least half of the total required capital
must be "Tier 1 capital," consisting principally of common shareholders' equity,
noncumulative perpetual preferred stock, a limited amount of cumulative
perpetual preferred stock and minority interest in the equity accounts of
consolidated subsidiaries, less certain goodwill items. The remainder ("Tier 2
capital") may consist of a limited amount of subordinated debt and intermediate-
term preferred stock, certain hybrid capital instruments and other debt
securities, cumulative perpetual preferred stock, and a limited amount of the
general loan loss allowance. In addition to the risk-based capital guidelines,
the Federal Reserve has adopted a Tier 1 (leverage) capital ratio under which
the bank holding company must maintain a minimum level of Tier 1 capital to
average total consolidated assets of 3% in the case of bank holding companies
which have the highest regulatory examination ratings and are not contemplating
significant growth or

                                     -47-
<PAGE>
 
expansion. All other bank holding companies are expected to maintain a ratio of
at least 1% to 2% above the stated minimum.

     The following is ONB's regulatory capital ratios as of December 31, 1995:
 
                                 ONB
                                -----
 
               Tier 1 Capital:  13.39%
 
               Total Capital:   15.60%
 
               Leverage Ratio:   8.37%

BANK REGULATION

     Carmi and the affiliate banks of ONB which are national banks are
supervised, regulated and examined by the OCC. The affiliate banks of ONB which
are state banks chartered in Indiana, are supervised, regulated and examined by
the Indiana Department of Financial Institutions. ONB's affiliate banks
chartered in Kentucky are supervised, regulated and examined by the Kentucky
Department of Financial Institutions and those affiliate banks chartered in
Illinois are supervised, regulated and examined by the ICBT. In addition, those
ONB affiliate banks which are state banks and members of the Federal Reserve are
supervised and regulated by the Federal Reserve, and those which are not members
of the Federal Reserve are supervised and regulated by the FDIC. Carmi, as a
national banking association, is supervised, regulated and examined by the OCC
and will continue to be supervised, regulated and examined by the OCC following
consummation of the Affiliation. Each regulator has the authority to issue 
cease-and-desist orders if it determines that activities of the bank regularly
represent an unsafe and unsound banking practice or a violation of law.

     Both federal and state law extensively regulate various aspects of the
banking business such as reserve requirements, truth-in-lending and truth-in-
savings disclosure, equal credit opportunity, fair credit reporting, trading in
securities and other aspects of banking operations. Current federal law also
requires banks, among other things, to make deposited funds available within
specified time periods.

     Insured state-chartered banks are prohibited under FDICIA from engaging as
principal in activities that are not permitted for national banks, unless (i)
the FDIC determines that the activity would pose no significant risk to the
appropriate deposit insurance fund, and (ii) the bank is, and continues to be,
in compliance with all applicable capital standards.

BANK CAPITAL REQUIREMENTS

     The FDIC and the OCC have adopted risk-based capital ratio guidelines to
which state-chartered banks and national banks under their respective
supervision are subject. The guidelines establish a systematic analytical
framework that makes regulatory capital requirements more sensitive to
differences in risk profiles among banking organizations. Risk-based capital
ratios are determined by allocating assets and specified off-balance sheet
commitments to four risk weighted categories, with higher levels of capital
being required for the categories perceived as representing greater risk.

                                     -48-
<PAGE>
 
     Like the capital guidelines established by the Federal Reserve, these
guidelines divide a bank's capital into two tiers. Banks are required to
maintain a total risk-based capital ratio of 8%. The FDIC or OCC may, however,
set higher capital requirements when a bank's particular circumstances warrant.
Banks experiencing or anticipating significant growth are expected to maintain
capital ratios, including tangible capital positions, well above the minimum
levels.

     In addition, the FDIC and OCC established guidelines prescribing a minimum
Tier 1 leverage ratio (Tier 1 capital to adjusted total assets as specified in
the guidelines). These guidelines provide for a minimum Tier 1 leverage ratio of
3% for banks that meet certain specified criteria, including that they have the
highest regulatory rating and are not experiencing or anticipating significant
growth. All other banks are required to maintain a Tier 1 leverage ratio of 3%
plus an additional 100 to 200 basis points.

     All of ONB's affiliate banks, as well as Carmi, exceed the risk-based
capital guidelines of the FDIC and OCC as of December 31, 1995.

     The capital requirements described above are minimum requirements. Higher
capital levels will be required by the federal banking regulators if warranted
by the particular circumstances or risk profiles of individual institutions. For
example, the regulations of both the FDIC and the OCC provide that additional
capital may be required to take adequate account of the risks posed by
concentrations of credit and nontraditional activities, interest rate risk and
the bank's ability to manage such risks. As of December 31, 1995, none of ONB's
affiliate banks or Carmi had been directed by its primary federal regulator to
maintain capital at a level in excess of the minimum regulatory requirements.

BRANCHES AND AFFILIATES

     Branching by ONB affiliate banks in Indiana, Kentucky and Illinois is
subject to the jurisdiction, and requires the prior approval of, the bank's
primary federal regulatory authority and, if the branching bank is a state bank,
the Indiana Department of Financial Institutions, the Kentucky Department of
Financial Institutions or the ICBT (depending upon the location of the principal
office of the bank).

     ONB's affiliate banks and Carmi are subject to the Federal Reserve Act,
which restricts financial transactions between banks and affiliated companies.
The statute limits credit transactions between a bank and its executive officers
and its affiliates, prescribes terms and conditions for bank affiliate
transactions deemed to be consistent with safe and sound banking practices, and
restricts the types of collateral security permitted in connection with a bank's
extension of credit to an affiliate.

FDICIA

      FDICIA requires, among other things, federal bank regulatory authorities
to take "prompt corrective action" with respect to banks which do not meet
minimum capital requirements. For these purposes, FDICIA establishes five
capital tiers: well capitalized, adequately capitalized, undercapitalized,
significantly undercapitalized and critically undercapitalized.

     The FDIC has adopted regulations to implement the prompt corrective action
provisions of FDICIA. Among other things, the regulations define the relevant
capital measures for the five capital categories. An institution is deemed to be
"well capitalized" if it has a total risk-based

                                     -49-
<PAGE>
 
capital ratio of 10% or greater, a Tier 1 risk-based capital ratio of 6% or
greater, and a leverage ratio of 5% or greater, and is not subject to a
regulatory order, agreement or directive to meet and maintain a specific capital
level for any capital measure. An institution is deemed to be "adequately
capitalized" if it has a total risk-based capital ratio of 8% or greater, a Tier
1 risk-based capital ratio of 4% or greater, generally a leverage ratio 4% or
greater and does not meet the definition of a well-capitalized institution. An
institution is deemed to be "undercapitalized" if it has a total risk-based
capital ratio of less than 8%, a Tier 1 risk-based capital ratio of less than
4%, or generally a leverage ratio of less than 4%, and "significantly
undercapitalized" if it has a total risk-based capital ratio of less than 6%, a
Tier 1 risk-based capital ratio of less than 3%, or a leverage ratio of less
than 3%. An institution is deemed to be "critically undercapitalized" if it has
a ratio of tangible equity (as defined in the regulations) to total assets that
is equal to or less than 2%.

     "Undercapitalized" banks are subject to growth limitations and are required
to submit a capital restoration plan. A bank's compliance with such plan is
required to be guaranteed by any company that controls the undercapitalized
institution as described above. If an "undercapitalized" bank fails to submit an
acceptable plan, it is treated as if it is significantly undercapitalized.
"Significantly undercapitalized" banks are subject to one or more of a number of
requirements and restrictions, including an order by the FDIC to sell sufficient
voting stock to become adequately capitalized, requirements to reduce total
assets and cease receipt of deposits from correspondent banks, and restrictions
on compensation of executive officers. "Critically undercapitalized"
institutions may not, beginning 60 days after becoming "critically
undercapitalized", make any payment of principal or interest on certain
subordinated debt or extend credit for a highly leveraged transaction or enter
into any transaction outside the ordinary course of business. In addition,
"critically undercapitalized" institutions are subject to appointment of a
receiver or conservator.

     On July 10, 1995, the federal banking regulators, including the FDIC and
the OCC, published final guidelines establishing operational and managerial
standards to promote the safety and soundness of federally insured depository
institutions. The guidelines, which took effect on August 9, 1995, establish
standards for internal controls, information systems, internal audit systems,
loan documentation, credit underwriting, interest rate exposure, asset growth,
and compensation, fees and benefits. In general, the guidelines prescribe the
goals to be achieved in each area, and each institution will be responsible for
establishing its own procedures to achieve those goals. If an institution fails
to comply with any of the standards set forth in the guidelines, the
institution's primary federal regulator may require the institution to submit a
plan for achieving and maintaining compliance. The preamble to the guidelines
states that the agencies expect to require a compliance plan from an institution
whose failure to meet one or more of the standards is of such severity that it
could threaten the safe and sound operation of the institution. Failure to
submit an acceptable compliance plan, or failure to adhere to a compliance plan
that has been accepted by the appropriate regulator, would constitute grounds
for further enforcement action. The federal banking agencies have also published
for comment proposed asset quality and earnings standards which, if adopted,
would be added to the safety and soundness guidelines. This proposal, like the
final guidelines discussed above, would establish the goals to be achieved with
respect to asset quality and earnings, and each institution would be responsible
for establishing its own procedures to meet such goals.

DEPOSIT INSURANCE

     The deposits of ONB's affiliate banks and Carmi are insured up to $100,000
per insured account, by the Bank Insurance Fund ("BIF"), except for deposits
acquired in connection with 

                                     -50-
<PAGE>
 
affiliations with savings associations, which deposits are insured by the
Savings Association Insurance Fund ("SAIF"). Accordingly, deposit insurance
premiums are paid to both BIF and SAIF. If the FDIC believes that an increase in
the insurance rates is necessary, it may increase the insurance premiums
applicable to the BIF.

     The amount each institution pays for FDIC deposit insurance coverage is
determined in accordance with a risk-based assessment under which all insured
depository institutions are placed into one of nine categories and assessed
insurance premiums based upon their level of capital and supervisory evaluation.
Institutions classified as well-capitalized (as defined by the FDIC) and
considered healthy pay the lowest premium while institutions that are less than
adequately capitalized (as defined by the FDIC) and considered of substantial
supervisory concern pay the highest premium. For the semi-annual assessment
period ended December 31, 1995, BIF assessments ranged from 0.04% to 0.31% of
deposits while SAIF assessments ranged from 0.23% to 0.31% of deposits. For the
semi-annual assessment period beginning January 1, 1996, BIF assessments will
range from nearly 0% (statutory minimum assessment of $1,000 paid to the BIF) to
0.27% of deposits while SAIF assessments will range from 0.23% to 0.31% of
deposits. Risk classification of all insured institutions is made by the FDIC
for each semi-annual assessment period.

     The supervisory subgroup to which an institution is assigned by the FDIC is
confidential and may not be disclosed. Deposit insurance assessments may
increase or decrease depending upon the category and subcategory, if any, to
which the bank is assigned by the FDIC and upon regulatory changes. Any increase
in insurance assessments could have an adverse effect on the earnings of ONB's
affiliate banks and Carmi, and any decrease could have a positive effect on the
earnings of ONB's affiliate banks and Carmi.

INTERSTATE BANKING

     In 1994, Congress enacted sweeping changes to the interstate branching and
expansion powers of depository institutions and their holding companies in The
Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 ("Riegle-
Neal") which allows for interstate banking and interstate branching without
regard to whether such activity is permissible under state law. Beginning on
September 29, 1995, bank holding companies may acquire banks anywhere in the
United States subject to certain state restrictions. Beginning on June 1, 1997,
an insured bank may merge with an insured bank in another state without regard
to whether such merger is prohibited by state law. Additionally, an out-of-state
bank may acquire the branches of an insured bank in another state without
acquiring the entire bank; provided, however, that the law of the state where
the branch is located permits such an acquisition. States may permit interstate
branching earlier than June 1, 1997, where both states involved with the bank
merger expressly permit it by statute. Further, bank holding companies may merge
existing bank subsidiaries located in different states into one bank. Indiana
now permits interstate branching (both de novo and by acquisition) in accordance
with Riegle-Neal subject to certain conditions. Illinois enacted interstate
branching legislation which is effective on June 1, 1997. The Illinois
legislation does not permit de novo branching into Illinois by an out-of-state
bank or the acquisition of a branch in Illinois without the acquisition of the
entire bank.

     Beginning on September 29, 1995, an insured bank subsidiary may act as an
agent for an affiliated bank or thrift in offering limited banking services
(receive deposits, renew time deposits, close loans, service loans and receive
payments on loans obligations) both within the same state and across state
lines.

                                     -51-

ADDITIONAL MATTERS

     In addition to the matters discussed above, ONB's affiliate banks and Carmi
are subject to additional regulation of their activities, including a variety of
consumer protection regulations affecting their lending, deposit and collection
activities and regulations affecting secondary mortgage market activities.

     The extensive regulation, supervision and examination of financial
institutions by the bank regulatory agencies is intended primarily for the
protection of the insurance fund and depositors.  Moreover, such regulation
imposes substantial restrictions on the operations and activities of such
institutions, and grants to regulators broad discretion in connection with their
supervisory and enforcement activities and examination policies, including
policies with respect to classification of assets and establishment of adequate
loan loss reserves.  Any changes in such regulations, whether by legislation or
regulatory action, could have a material impact on ONB's affiliate banks and
their operations.  ONB cannot predict what, if any, future actions may be taken
by legislative or regulatory authorities or what impact any such actions may
have on the operations of its affiliates.

     The earnings of financial institutions are also affected by general
economic conditions and prevailing interest rates, both domestic and foreign and
by the monetary and fiscal policies of the United States Government and its
various agencies, particularly the Federal Reserve.

     Additional legislation and administrative actions affecting the banking
industry are being considered and in the future may be considered by the United
States Congress, state legislatures and various regulatory agencies, including
those referred to above.  It cannot be predicted with certainty whether such
legislation of administrative action will be enacted or the extent to which the
banking industry in general or Carmi or ONB and its affiliate banks in
particular would be affected thereby.

                           COMPARISON OF COMMON STOCK

     The rights of holders of Carmi Common Stock who receive ONB Common Stock in
the Affiliation will be governed by the laws of the State of Indiana, the state
in which ONB is incorporated, and by ONB's Amended and Restated Articles of
Incorporation ("ONB's Articles of Incorporation") and ONB's By-Laws, as amended
("ONB's By-Laws").  The rights of the shareholders of Carmi are presently
governed by the laws of the United States of America, and by Carmi's Articles of
Association ("Carmi's Articles") and By-Laws.  The rights of the shareholders of
Carmi differ in certain respects from the rights they would have as ONB
shareholders, including ONB's anti-takeover measures and the vote required for
the amendment of significant provisions of the articles of incorporation and for
the approval of significant corporate transactions.  The following summary
comparison of ONB Common Stock and Carmi Common Stock includes all material
features of such shares but does not purport to be complete and is qualified in
its entirety by reference to ONB's Articles and By-Laws and Carmi's Articles and
By-Laws.

AUTHORIZED BUT UNISSUED SHARES

     ONB's Articles of Incorporation authorize the issuance of 30,000,000 shares
of ONB Common Stock, of which 24,835,361 whole shares were outstanding as of
February 29, 1996.  The remaining authorized but unissued shares of common stock
may be issued upon authorization of the Board of Directors of ONB without prior
shareholder approval.  ONB has 2,000,000 shares of 

                                      -52-
<PAGE>
 
preferred stock authorized. These shares are available to be issued, without
prior shareholder approval, in classes with relative rights, privileges and
preferences determined for each class by the Board of Directors of ONB. No
shares of preferred stock are presently outstanding.

     The Board of Directors of ONB has concluded that it is in the best
interests of ONB and its shareholders to increase the amount of ONB's authorized
common stock from 30 million to 50 million shares.  At ONB's annual shareholder
meeting held on April 18, 1996, the shareholders voted to adopt an amendment to
ONB's Articles of Incorporation increasing the number of shares of authorized 
common stock. The amendment will be effective upon the filing of Articles of
Amendment to ONB's Articles of Incorporation with the Indiana Secretary of
State.

     The Board of Directors of ONB has authorized a series of preferred stock
designated as Series A preferred stock.  The Board of Directors of ONB has
designated 200,000 shares of Series A preferred stock in connection with the
shareholder rights plan of ONB.  The ONB Series A preferred stock may not be
issued except upon exercise of certain rights pursuant to such shareholder
rights plan.  No shares of Series A preferred stock have been issued as of the
date of this Proxy Statement.  See "COMPARISON OF COMMON STOCK -- Anti-Takeover
Provisions -- ONB's Shareholder Rights Plan" below.

     The shares of ONB Series A preferred stock are nonredeemable and, unless
otherwise provided in connection with the creation of a subsequent series of
preferred stock, are subordinate to all other series of preferred stock of ONB.
Each share of ONB Series A preferred stock will be entitled to receive, when, as
and if declared, a quarterly dividend in an amount equal to the greater of $1.00
per share or 100 times the quarterly cash dividend declared on ONB Common Stock.
In addition, the ONB Series A preferred stock is entitled to 100 times any non-
cash dividends (other than dividends payable in equity securities) declared on
the ONB Common Stock, in like kind.  In the event of liquidation, the holders of
ONB Series A preferred stock will be entitled to receive a liquidation payment
in an amount equal to the greater of $100.00 per share or 100 times the
liquidation payment made per share of ONB Common Stock.  Each share of ONB
Series A preferred stock will have 100 votes, subject to adjustment, voting
together with the ONB Common Stock and not as a separate class unless otherwise
required by law or ONB's Articles of Incorporation.  In the event of any merger,
consolidation or other transaction in which common shares are exchanged, each
share of ONB Series A preferred stock will be entitled to receive 100 times the
amount received per share of ONB Common Stock.  The rights of the ONB Series A
preferred stock as to dividends, voting rights and liquidation are protected by
antidilution provisions.  See "COMPARISON OF COMMON STOCK -- Anti-Takeover
Provisions".

     As of December 31, 1995, ONB had approximately 1,394,041 shares of ONB
Common Stock reserved for issuance under ONB's dividend reinvestment and stock
purchase plan and 1,406,919 million shares of its common stock reserved for
issuance upon conversion of its outstanding 8% convertible subordinated
debentures (as adjusted for the 5% stock dividend issued by ONB on February 20,
1996).  Such debentures are convertible at any time prior to maturity, unless
previously redeemed, into shares of ONB Common Stock at a conversion rate of
44.643 shares per $1,000 principal amount of debentures (equivalent to a
conversion price of approximately $22.40 per share), subject to adjustment in
certain events.

                                      -53-
<PAGE>
 
     The issuance of additional shares of ONB Common Stock to persons who were
not holders of ONB Common Stock prior to such issuance or the issuance of ONB
preferred stock may adversely affect the interests of ONB shareholders.

     Carmi's Articles authorize the issuance of 100,000 shares of Carmi Common
Stock, $10.00 par value per share, all of which were outstanding as of December
31, 1995. Following the Affiliation, all of the outstanding shares of Carmi
Common Stock will be held by ONB.

PREEMPTIVE RIGHTS

     As permitted by Indiana law, ONB's Articles of Incorporation do not provide
for preemptive rights to subscribe for any new or additional ONB Common Stock or
other securities.  Preemptive rights may be granted to ONB's shareholders if
ONB's Articles of Incorporation are amended accordingly.  Under Carmi's
Articles, shareholders of Carmi have do not have preemptive rights to subscribe
for any new or additional shares of Carmi Common Stock or other securities or
indebtedness.

DIVIDEND RIGHTS

     The holders of common stock of ONB and Carmi are entitled to dividends and
other distributions when, as and if declared by their respective Boards of
Directors out of funds legally available therefor.  With respect to ONB, a
dividend may not be paid if, after giving it effect, (1) ONB would not be able
to pay its debts as they become due in the usual course of business, or (2)
ONB's total assets would be less than the sum of its total liabilities plus,
unless ONB's Articles of Incorporation permitted otherwise, the amount that
would be needed to satisfy the preferential rights upon dissolution of
shareholders whose preferential rights are superior to those receiving the
dividend if ONB were to be dissolved at the time of the dividend. With respect
to Carmi, it may pay cash dividends on its shares of common stock only out of
adjusted retained net profits for the year in which the dividend is paid and the
two (2) preceding years.

     The amount of dividends, if any, that may be declared by ONB in the future
will necessarily depend upon many factors, including, without limitation, future
earnings, capital requirements, business conditions and capital levels of
subsidiaries (since ONB is primarily dependent upon dividends paid by its
subsidiaries for its revenues), the discretion of ONB's Board of Directors and
other factors that may be appropriate in determining dividend policies.

     Cash dividends paid to ONB by its Illinois-chartered affiliate banks are
limited by Illinois law to the bank's net profits then on hand, less losses and
statutorily-defined bad debts.  Cash dividends paid to ONB by its Indiana-
chartered affiliate banks are limited by Indiana law to the balance of the
bank's undivided profits account adjusted for statutorily-defined bad debts.
Cash dividends paid to ONB by its Kentucky-chartered affiliate banks are limited
by Kentucky law to so much of the net profits of the banks, after deducting all
expenses, losses, bad or suspended debts and interest and taxes accrued or due
from the banks, as the boards of directors of the banks deem expedient.  In
addition, the approval of the Kentucky Commissioner of Banks is required if the
total of all dividends declared by a Kentucky bank in any calendar year exceeds
the bank's net profit for that year and the net retained profits from the
preceding two years, less any transfers to surplus or a fund for retirement of
preferred stock or debt.  ONB's national affiliate banks may pay cash dividends
on their common stock only out of adjusted retained net profits for the year in
which the dividend is paid and the two preceding years.

                                      -54-
<PAGE>
 
     Dividends paid by Carmi and ONB's affiliate banks will ordinarily be
restricted to a lesser amount than is legally permissible because of the need
for the banks to maintain adequate capital consistent with the capital adequacy
guidelines promulgated by the banks' principal federal regulatory authorities.
See "REGULATORY CONSIDERATIONS".  If a bank's capital levels are deemed
inadequate by the regulatory authorities, payment of dividends to its parent
holding company may be prohibited without prior regulatory approval.  None of
ONB's affiliate banks or Carmi is currently subject to such a restriction.

VOTING RIGHTS

     The holders of the outstanding shares of ONB Common Stock and Carmi Common
Stock are entitled to one vote per share on all matters presented for
shareholder vote.  Shareholders of ONB do not have cumulative voting rights in
the election of directors while shareholders of Carmi do have cumulative voting
rights in the election of directors.

     Indiana law generally requires that mergers, consolidations, sales, leases,
exchanges or other dispositions of all or substantially all of the assets of a
corporation be approved by the affirmative vote, as specified in the
corporation's by-laws, of the issued and outstanding shares entitled to vote at
the shareholders meeting, subject in each case to provisions in the
corporation's articles of incorporation requiring a higher percentage vote for
certain transactions.  ONB's Articles of Incorporation provide that certain
business combinations may, under certain circumstances, require approval of more
than a simple majority of the issued and outstanding shares of ONB Common Stock.
Indiana law permits a corporation in its articles of incorporation to prescribe
a higher shareholder vote for certain amendments to the articles of
incorporation. See "COMPARISON OF COMMON STOCK -- Anti-Takeover Provisions".
Under the National Bank Act, as amended, a national bank may merge or
consolidate with another national bank or state bank if such transaction is
approved by a majority of the directors of the national bank and the holders of
at least two-thirds of its voting shares.

     Indiana law requires shareholder approval for most amendments to a
corporation's articles of incorporation by a majority of a quorum present at a
shareholders' meeting (and, in certain cases, a majority of all shares held by
any voting group entitled to vote). Indiana law permits a corporation in its
articles of incorporation to prescribe a higher shareholder vote for certain
amendments to the articles of incorporation.  ONB's Articles of Incorporation
require a super-majority shareholder vote of eighty percent (80%) of the
outstanding shares of ONB Common Stock for the amendment of certain significant
provisions.  Under the National Bank Act, as amended, an association's articles
of association may be amended by a majority of the voting shares of the stock of
the association.

DISSENTERS' RIGHTS

     The shareholders of Indiana business corporations possess dissenters'
rights in connection with certain mergers and other significant corporate
actions.  Under Indiana law, a shareholder is entitled to dissent from and
obtain payment of the fair value of the shareholder's shares in the event of (1)
consummation of a plan of merger, if shareholder approval is required and the
shareholder is entitled to vote thereon, (2) consummation of a plan of share
exchange by which the shareholder's shares will be acquired, if the shareholder
is entitled to vote thereon, (3) consummation of a sale or exchange of all, or
substantially all, the property of the corporation other than in the usual
course of business, if the shareholder is entitled to vote thereon, (4) approval
of a control share acquisition under Indiana law, and (5) any corporate action
taken pursuant to a shareholder vote to the extent 

                                      -55-
<PAGE>
 
the articles of incorporation, by-laws or a resolution of the Board of Directors
provides that voting or non-voting shareholders are entitled to dissent and
obtain payment for their shares.

     The dissenters' rights provisions described above do not apply, however, to
the holders of shares of any class or series with respect to a merger, share
exchange or sale or exchange of property if the shares of that class or series
were registered on a United States securities exchange registered under the
Exchange Act or traded on the Nasdaq National Market System or a similar market.
As of the date of this Proxy Statement, shares of ONB Common Stock are traded on
the Nasdaq National Market System and, therefore, ONB shareholders presently are
not entitled to assert dissenters' rights under Indiana law with respect to any
of the transactions discussed above.

     With respect to dissenters' rights of the shareholders of Carmi in
connection with the Affiliation, see the discussion under the caption "PROPOSED
AFFILIATION -- Rights of Dissenting Shareholders" and Appendices B and C.

LIQUIDATION RIGHTS

     In the event of any liquidation or dissolution of ONB, the holders of
shares of ONB Common Stock are entitled to receive pro rata with respect to the
number of shares held by them any assets distributable to shareholders, subject
to the payment of ONB's liabilities and any rights of creditors and holders of
shares of ONB preferred stock then outstanding. In the event of any liquidation,
dissolution or winding up of Carmi, the holders of shares of Carmi Common Stock
are entitled to receive pro rata with respect to the number of shares held by
them any assets distributable to shareholders, subject to the payment of Carmi's
liabilities and any rights of creditors.

ASSESSMENT AND REDEMPTION

     Under Indiana law, certain shares of ONB Common Stock are not liable to
further assessment.  Under the National Bank Act, as amended, shares of Carmi
Common Stock are liable to further assessment under certain limited
circumstances.

     Under Indiana law, ONB may redeem or acquire shares of ONB Common Stock
with funds legally available therefor, and shares so acquired constitute
authorized  but unissued shares.  ONB may not redeem or acquire shares of ONB
Common Stock if, after giving such redemption or acquisition effect, ONB would
not be able to pay its debts as they become due in the usual course of business,
or ONB's total assets would be less than the sum of its total liabilities plus,
unless ONB's Articles of Incorporation permitted otherwise, the amount that
would be needed to satisfy the preferential rights upon dissolution of
shareholders whose preferential rights are superior to those whose stock is
being redeemed or acquired if ONB were to be dissolved at the time of the
redemption or acquisition.  Carmi has similar redemption rights under its
Articles.

     Federal Reserve regulations generally require a bank holding company to
give prior notice to the Federal Reserve if the consideration to be paid by it
for any redemption or acquisition of its shares, when aggregated with the
consideration paid for all redemptions or acquisitions for the preceding twelve
(12) months, equals or exceeds 10% of its consolidated net worth.  This
requirement does not, however, apply to a bank holding company which is deemed
to be "well-capitalized" as defined pursuant to FDICIA (see "Regulatory
Considerations -- FDICIA") and which received a composite rating of 1 or 2 at
its most recent Federal Reserve examination and 

                                      -56-
<PAGE>
 
which is not the subject of any unresolved supervisory issues. This requirement
does not apply to ONB.

ANTI-TAKEOVER PROVISIONS

     The anti-takeover measures applicable to ONB and Carmi, as described below,
may have the effect of discouraging or rendering it more difficult for a person
or other entity to acquire control of ONB or Carmi.  These measures may have the
effect of discouraging certain tender offers for shares of ONB Common Stock or
Carmi Common Stock which might otherwise be made at premium prices or certain
other acquisition transactions which might be viewed favorably by a significant
number of shareholders.

     Indiana Law.  Under the business combinations provision of Indiana law, any
10% shareholder of an Indiana corporation, with a class of voting shares
registered under Section 12 of the Exchange Act or which has specifically
adopted this provision in the corporation's articles of incorporation, is
prohibited for a period of five (5) years from completing a business combination
with the corporation unless, prior to the acquisition of such 10% interest, the
board of directors of the corporation approved either the acquisition of such
interest or the proposed business combination.  Further, the corporation and a
10% shareholder may not consummate a business combination unless all provisions
of the articles of incorporation of the corporation are complied with and a
majority of disinterested shareholders approve the transaction or all
shareholders receive a price per share determined in accordance with the
business combinations provision of Indiana law.

     An Indiana corporation may elect to remove itself from the protection
provided by the Indiana business combinations provision, but such an election
remains ineffective for eighteen (18) months and does not apply to a combination
with a shareholder who acquired a 10% ownership position prior to the effective
time of the election.  ONB is covered by the business combinations provision of
Indiana law and Carmi is not covered.  The constitutional validity of the
business combinations provision of Indiana law has in the past been challenged
and has been upheld by the United States Supreme Court.

     In addition to the business combinations provision, Indiana law also
contains a "control share acquisition" provision which, although different in
structure from the business combinations provision, may have a similar effect of
discouraging or making more difficult a hostile takeover of an Indiana
corporation.  This provision also may have the effect of discouraging premium
bids for outstanding shares.  Indiana law provides that, unless otherwise
provided in an Indiana corporation's articles of incorporation or by-laws,
certain acquisitions of shares of the corporation's common stock will be
accorded voting rights only if a majority of the disinterested shareholders
approves a resolution granting the potential acquiror the ability to vote such
shares.  Upon disapproval of the resolution, the shares held by the acquiror
shall be redeemed by the corporation at the fair value of the shares as
determined by the control share acquisition provision.

     This provision does not apply to a plan of affiliation and merger if the
corporation complies with the applicable merger provisions and is a party to the
agreement of merger or plan of share exchange.  ONB is subject to the control
share acquisition provision.

     ONB's Articles of Incorporation.  In addition to the protections provided
by Indiana law, ONB's Articles of Incorporation require the affirmative vote of
the holders of at least eighty percent (80%) of the issued and outstanding
shares of capital stock for any business combination which is 

                                      -57-
<PAGE>
 
not recommended by the vote of two-thirds or more of the members of the Board of
Directors. For purposes of ONB's Articles of Incorporation, "business
combination" is defined to include: (1) a merger or consolidation of ONB with or
into any other corporation, (2) any sale, lease, exchange or other disposition
of any material part of the assets of ONB, or (3) any liquidation or dissolution
of ONB or any material subsidiary of ONB. Further, this provision cannot be
altered, amended or repealed without the affirmative vote of the holders of at
least eighty percent (80%) of the issued and outstanding shares of ONB Common
Stock entitled to vote thereon.

     ONB's Articles of Incorporation also include provisions requiring (1) the
Board of Directors to consider non-financial factors in the evaluation of
business combinations and tender or exchange offers, and (2) any person
acquiring fifteen percent (15%) of the then issued and outstanding stock of ONB
to pay equal consideration in connection with the acquisition of any further
shares.  These provisions require an eighty percent (80%) affirmative vote of
the issued and outstanding shares of ONB Common Stock entitled to vote thereon
in order to be altered, amended or repealed.

     ONB's Shareholder Rights Plan.  On January 25, 1990, the Board of Directors
of ONB declared a dividend of one (1) right for each issued and outstanding
share of ONB Common Stock ("Right").  See "COMPARISON OF COMMON STOCK --
Authorized But Unissued Shares".  The dividend was payable on March 15, 1990 to
holders of record of ONB Common Stock at the close of business on March 1, 1990.
Each Right entitles the registered holder, upon the occurrence of certain events
involving a change in control of ONB, to purchase from ONB one-hundredth (1/100)
of a share of ONB Series A preferred stock at an initial Purchase Price of
$60.00, subject to adjustment.  The terms and conditions of the Rights are
contained in a Rights Agreement between ONB and Old National Bank in Evansville,
as Rights Agent.

     The foregoing information concerning ONB's shareholder Rights Plan does not
purport to be complete.  For additional information, see The Rights Agreement,
dated March 1, 1990, between ONB and Old National Bank in Evansville, as
Trustee, which is specifically incorporated herein by reference.  See
"INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."

     Carmi's Articles.  Certain of the corporate governance provisions which are
part of Carmi's Articles could discourage or frustrate future attempts to
acquire control of Carmi by possibly making it more difficult to change the
composition of the incumbent Board of Directors of Carmi.  Article Fourth of
Carmi's Articles provides that a stockholder must furnish written notice to the
president of Carmi, not less than 14 nor more than 50 days prior to the meeting
as originally scheduled, of a stockholder's nomination of a candidate for
election to the Board of Directors.  Article Fourth further provides that a
stockholders' notice with respect to the nomination of candidates to the Board
of Directors of Carmi must contain:  (a) the name and residence address of the
stockholder who intends to make the nomination; (b) the name and residence
address, and principal occupation or employment of each nominee, and (c) the
number of shares of capital stock that will be voted for the nominee.  The
procedures set for the in Article Fourth would prohibit last-minute attempts by
any stockholder to nominate an individual for election to the Board of Directors
of Carmi at a stockholders' meeting, even if such a nomination might be desired
by a majority of stockholders.

DIRECTOR LIABILITY

     Under Indiana law, a director of ONB will not be liable to shareholders for
any action taken as a director, or any failure to take any action, unless (1)
the director has breached or failed to perform his duties as a director in good
faith with the care an ordinarily prudent person in a like 



                                      -58-

DIRECTOR NOMINATIONS

     ONB's By-Laws require that all nominations for election as directors of ONB
shall be made by the Board of Directors of ONB in accordance with the By-Laws.
Under the By-Laws, the Nominating Committee of the Board of Directors of ONB
("Nominating Committee") is required to submit to the entire Board of Directors
its recommendation of nominees for election as directors of ONB prior to each
annual or special meeting of shareholders at which directors will be elected.

     The Nominating Committee is comprised of five (5) directors of ONB, none of
whom is an officer or employee of ONB.  The Nominating Committee maintains the
responsibility to recruit potential director candidates, recommend changes to
the entire Board of Directors concerning the size, composition and
responsibilities of the Board of Directors, review proxy documents received from
shareholders relating to the Board of Directors and review suggestions of
shareholders regarding nominees for election as directors.  All such suggestions
of shareholders with respect to director nominations must be submitted in
writing to the Nominating Committee not less than 120 days prior to the date of
the annual or special meeting of shareholders at which directors will be
elected.

     Carmi's Articles of Association allow for the nomination for election to
the Board of Directors to be made by the existing Board of Directors or by any
of its shareholders.

                                 LEGAL OPINIONS

                          INDEPENDENT AUDITORS' REPORT



Board of Directors
The National Bank of Carmi


We have audited the accompanying balance sheets of The National Bank of Carmi,
Carmi, Illinois as of December 31, 1995 and 1994 and the related statements of
income, changes in stockholders' equity and cash flows each of the years in the
three-year period ended December 31, 1995.  These financial statements are the
responsibility of the Bank's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of The National Bank of Carmi,
Carmi, Illinois as of December 31, 1995 and 1994, and the results of its
operations and its cash flows for each of the years in the three-year period
ended December 31, 1995, in conformity with generally accepted accounting
principles.

Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole.  The schedule of operating expenses on page 14 is
presented for the purposes of additional analysis and is not a required part of
the basic financial statements.  Such information has been subjected to the
auditing procedures applied in the audit of the basic financial statements and,
in our opinion, is fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

                           THE NATIONAL BANK OF CARMI

                         NOTES TO FINANCIAL STATEMENTS

                        DECEMBER 31, 1995, 1994 AND 1993


1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     NATURE OF OPERATIONS
     The National Bank of Carmi provides a variety of banking services to
     individuals and businesses through its two facilities in Carmi and
     Crossville.  Its primary deposit products are demand deposits and
     certificates of deposit, and its primary lending products are commercial
     business, real estate mortgage, and installment loans.

     USE OF ESTIMATES
     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities
     and disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period.  Actual results could differ from those
     estimates.

     INVESTMENT SECURITIES
     The Bank adopted Financial Accounting Standard No. 115 "Accounting for
     Certain Investments in Debt and Equity Securities" (FAS 115) as of the
     beginning of 1994.  This new accounting policy expands the use of fair
     value accounting for securities for which there is not a positive intent
     and ability to hold to maturity.  At acquisition, FAS 115 requires that
     securities be classified into one of three categories:  trading,
     available for sale or investment.  Trading securities are bought and held
     principally with the intention of selling them in the near term.  The
     Bank has no trading securities.  Investment securities are those
     securities for which the Bank has the ability and intent to hold until
     maturity.  All other debt securities are classified as available for
     sale.  Other securities include stock in the Federal Reserve Bank. There
     was no effect of this change on 1994 net income.

     Securities available for sale are stated at fair value.  Fair value is
     based on market prices quoted in financial publications or other
     independent sources.  Net unrealized gains or losses are excluded from
     earnings and reported, net of deferred income taxes, as a separate
     component of shareholders' equity until realized.  The adjusted cost of
     the specific security available for sale that is sold is used to compute
     any gain or loss upon sale.

     Investment securities are carried at cost, adjusted for amortization of
     premiums and accretion of discounts, which are recognized as adjustments
     to interest income on the level-yield method.  Gain or loss is recorded
     when realized on a specific identity basis or when, in the opinion of
     management, an unrealized loss is other than temporary in nature.

     LOANS
     Loans are stated at the amount of unpaid principal, reduced by unearned
     discount and allowance for loan losses.  Unearned discount on installment
     loans is recognized as income over the terms of the loans by a method
     which approximates the level yield method.  Interest on commercial and
     real estate mortgage loans is accrued and credited to operations based
     upon the principal amount outstanding, using the simple interest method.
     Accrual of interest is discontinued on a loan when management believes,
     after considering economic and business conditions and collection
     efforts, 
 
                                      F-7
<PAGE>
 
     that the borrower's financial condition is such that collection
     of interest is doubtful.

     ALLOWANCE FOR LOAN LOSSES
     The allowance for loan losses is maintained at a level which, in
     management's judgment, is adequate to absorb credit losses inherent in
     the loan portfolio.    The amount of the allowance is based on
     management's evaluation of the collectibility of the loan portfolio,
     including the nature of the portfolio, credit concentrations, trends in
     historical loss experience, specific impaired loans, and economic
     conditions.  Allowances for impaired loans are generally determined based
     on collateral values or the present value of estimated cash flows. The
     allowance is increased by a provision for loan losses, which is charged
     to expense and reduced by charge-offs, net of recoveries.  Changes in the
     allowance relating to impaired loans are charged or credited to the
     provision for loan losses.  Because of uncertainties inherent in the
     estimation process, management's estimate of credit losses inherent in
     the loan portfolio and the related allowance may change in the near term.

     OTHER REAL ESTATE
     Real estate acquired through foreclosure is carried at the lower of the
     recorded investment in the loan for which the property previously served
     as collateral or the current appraised value of the foreclosed property.
     Any writedowns required prior to actual foreclosure are charged to the
     reserve for loan losses.  Subsequent to foreclosure, losses on the
     periodic revaluation of the property are charged to current period
     earnings as noninterest expense.  Gains and losses resulting from the
     sale of foreclosed property are credited or charged to current period
     earnings.  Costs of maintaining and operating foreclosed property are
     expensed as incurred and expenditures to complete or improve foreclosed
     properties are capitalized if the expenditures are expected to be
     recovered upon ultimate sale of the property.  Loans meeting in-substance
     foreclosure criteria are reported and accounted for consistent with
     treatment accorded foreclosed property.

     BANK PREMISES AND EQUIPMENT
     Bank premises and equipment are stated at cost less accumulated
     depreciation.  Depreciation is computed on the double declining and
     straight-line methods over the estimated useful lives.  Estimated useful
     lives on bank premises range from ten to forty years and five to fifteen
     years on equipment.  Expenditures for major renewals and improvements of
     premises and equipment are capitalized and those for maintenance and
     repairs are expensed as incurred.

     INCOME TAXES
     Provisions for income taxes are based on taxes payable or refundable for
     the current year (after exclusion of non-taxable income such as interest
     on state and municipal securities) and deferred taxes on temporary
     differences between the amount of taxable income and pretax financial
     income and between the tax bases of assets and liabilities and their
     reported amounts in the financial statements.  Deferred tax assets and
     liabilities are included in the financial statements at currently enacted
     income tax rates applicable to the period in which the deferred tax
     assets and liabilities are expected to be realized or settled as
     prescribed in FASB Statement No. 109, Accounting for Income Taxes.  As
     changes in tax laws or rates are enacted, deferred tax assets and
     liabilities are adjusted through the provision for income taxes.

     EARNINGS PER SHARE
     Earnings per share are calculated on the basis of the weighted average of
     common shares outstanding.

     CASH AND CASH EQUIVALENTS

     cash on hand, amounts due from banks and federal funds sold.

     RECLASSIFICATIONS

     the 1995 presentation.  Such reclassifications have no effect on net
     earnings or stockholders' equity as previously reported.

     Nonaccrual loans at December 31, 1995 and 1994 totaled $101,236.00 and
     $52,232.00, respectively. Officers, directors and employees of The National
     Bank of Carmi, and individuals related to such individuals incurred
     indebtedness in the form of loans as customers. These loans were made on
     substantially the same terms, including interest rates and collateral, as
     those prevailing at the time for comparable transactions with other
     customers and did not involve more than the normal risk of collectibility.
     The balance of these loans at December 31, 1995 and 1994 totaled

6.   INCOME TAX
     The provision for income taxes from continuing operations consists of the
     following components:

<TABLE> 
<CAPTION> 
                                          1995             1994           1993

     Current tax expense               $185,065.13      $170,336.39    $135,889.29
     Deferred tax expense (benefit)     (62,206.75)       66,672.85     (21,558.00)
                                       -----------      -----------    -----------
                                       $122,858.38      $237,009.24    $114,331.29
                                       ===========      ===========    ===========
</TABLE> 

     Temporary differences giving rise to the deferred tax asset consist
     primarily of the excess of bad debt expense and accretion on investment
     securities for financial reporting purposes over the amount for tax
     purposes and net operating loss and alternative minimum tax credit
     carryforwards.

     The Bank has available at December 31, 1995, unused operating loss
     carryforwards of $165,412.00 which expire in various years and an
     alternative minimum tax credit carryforward of $9,990.00 which has no
     expiration date.

7.   PENSION PLAN
     The Bank has a 401(k) plan covering substantially all of the employees.
     The total expense was $475.00 in 1995, $425.00 in 1994 and $375.00 in
     1993.  Plan costs include current services which are funded on a current
     basis.

8.   FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK
     The Bank is, in the normal course of business, a party to certain off-
     balance-sheet financial instruments with inherent credit risk.  These
     instruments, which include commitments to extend credit and standby
     letters of credit, are used by the Bank to meet the financing needs of
     its customers.  These instruments involve, to varying degrees, credit
     risk in excess of the amount recognized in the Bank's balance sheet.

     Financial instruments with off-balance-sheet credit risk for which the
     contract amounts represent potential risk were as follows:
<TABLE> 
<CAPTION> 
                                             1995             1994
                                        -------------    -------------
<S>                                     <C>              <C> 
     Commitments to extend credit       $2,572,780.00    $2,427,920.00
                                        =============    =============


     Standby letter of credit           $  196,326.90    $  123,525.00
                                        =============    =============
</TABLE> 

     The Bank's maximum exposure to credit loss under commitments to extend
     credit and standby letters of credit is the equivalent of the contractual
     amount of those instruments.  The same credit policies are used by the
     Bank in granting commitments and conditional obligations as are used in
     the extension of credit.

                                      F-12
<PAGE>
 
     Commitments to extend credit are legally binding agreements to lend to a
     borrower as long as the borrower performs in accordance with the terms of
     the contract.  Commitments generally have fixed expiration dates or other
     termination clauses.  As many of the commitments are expected to expire
     without being drawn upon, the total commitment amount does not
     necessarily represent future cash requirements.  Included in commitments
     are the unused portions of lines of credit.

     Standby letters of credit are commitments issued by the Bank to guarantee
     specific performance of a customer to a third party.

     Collateral may be required by both commitments and standby letters of
     credit in accordance with the normal credit evaluation process based upon
     the creditworthiness of the customer and the credit risk associated with
     the particular transaction.  Collateral held varies, but may include
     commercial real estate, accounts receivable, inventory and equipment.

9.   RETAINED EARNINGS
     Banking regulations limit the amount of dividends that may be paid
     without prior approval of the Bank's regulatory agency.  National Banks
     are prohibited from paying dividends in excess of the current year's net
     income plus retained income from the preceding two years, unless prior
     regulatory approval is obtained.  At December 31, 1995, no retained
     earnings were available for the payment of additional dividends without
     regulatory approval.

10.  ACQUISITION
     On December 17, 1993, the Bank acquired The First National Bank of
     Crossville, a $13.5 million asset bank in Crossville, Illinois.  The
     acquisition was accounted for as a purchase and, accordingly, the results
     of operations were included in the financial statements from the
     acquisition date.  The total cost of the acquisition was $2,584,026.03,
     which exceeded the fair value of the net assets by $1,411,456.73.  The
     excess is being amortized on the straight line method over 15 years.
     Amortization expense charged to operations for 1995 and 1994 was
     $93,811.04 and $94,383.18, respectively.

11.  FAIR VALUES OF FINANCIAL INSTRUMENTS
     The following methods and assumptions were used by the Bank in estimating
     fair values of financial instruments as disclosed herein:

     Cash and cash equivalents - The carrying amounts of cash and short-term
     instruments approximate their fair value.

     Securities held to maturity and securities available for sale - Fair
     values for investment securities, excluding restricted equity securities,
     are based on quoted market prices.  The carrying values of restricted
     equity securities approximate fair values.

     Loans receivable - For variable-rate loans that reprice frequently and
     have no significant change in credit risk, fair values are based on
     carrying values.  Fair values for certain mortgage loans (e.g., one-to-
     four family residential), credit card loans, other consumer loans,
     commercial real estate and commercial loans are estimated using
     discounted cash flow analyses, using interest rates currently being
     offered for loans with similar terms to borrowers of similar credit
     quality.  Fair values for impaired loans are estimated using discounted
     cash flow analyses or underlying collateral values, where applicable.

     Deposit liabilities - The fair values disclosed for demand deposits are,
     by definition, equal to the amount payable on demand at the reporting
     date (that is, their carrying amounts).  The carrying amounts of
     variable-rate, fixed-term money market accounts and certificates of
     deposit approximate their fair values at the reporting date.  Fair values
     for fixed-rate certificates of deposit are estimated using a discounted
     cash flow calculation that applies interest rates currently being offered
     on certificates to a schedule of aggregated expected monthly maturities
     on time deposits.

                                       F-13
<PAGE>
 
     Short-term borrowings - The carrying amounts of borrowings under
     repurchase agreements and other short-term borrowings maturing within 90
     days approximate their fair values.  Fair values of other short-term
     borrowings are estimated using discounted cash flow analyses based on the
     Bank's current incremental borrowing rates for similar types of borrowing
     arrangements.

     Accrued interest - The carrying amounts of accrued interest approximate
     their fair values.

     The Bank, in accordance with FAS No. 107, has estimated fair values of
     financial instruments as follows:

</TABLE>

12.  CAPITAL RESTRICTIONS
     Banking regulations require minimum ratios of capital to total "risk
     weighted" assets.  The Bank is required to have minimum Tier I and total
     capital ratios of 4.00% and 8.00%, respectively.  At December 31, 1995
     and 1994, the Bank's actual capital ratios exceeded minimum requirements.

13.  CONCENTRATION OF CREDIT RISK
     Practically all of the Bank's loans, commitments, and commercial and
     standby letters of credit have been granted to customers in the Bank's
     market area.  Practically all such customers are depositors of the Bank.
     Investment in state and municipal securities also include governmental
     entities within the Bank's market area.  The concentration of credit by
     type of loan are set forth in Note 4.

     At December 31, 1995, the Bank's cash included one commercial bank
     deposit account aggregating $299,545.48 in excess of the Federal Deposit
     Insurance Corporation limit of $100,000.00 per institution.

14.  SHORT-TERM BORROWINGS
     Securities sold under agreements to repurchase mature within 90 days from
     the transaction date.

15.  SUBSEQUENT EVENT
     The Board of Directors of The National Bank of Carmi have agreed, subject
     to regulatory and stockholder approval, to merge with Old National
     Bancorp during 1996.

                                   SECTION 2

                                MANNER AND BASIS
                              OF EXCHANGE OF STOCK
                              --------------------

     2.01.  Exchange Ratio.  (a)  Upon and by virtue of the Merger becoming
effective at the Effective Time, each issued and outstanding share of Carmi
Common Stock (as defined in Section 4.03 hereof) shall be converted into the
right to receive three and 885/1000 (3.885) shares of ONB common stock
("Exchange Ratio"), subject to adjustment, if any, pursuant to the provisions of
this Section 2.01 and Section 2.03 hereof.

     (b)    If the Average Price Per Share (as hereinafter defined) of ONB
common stock is greater than $35.75 or less than $29.25, then the Exchange Ratio
shall be adjusted prior to the Effective Time as provided by Section 2.01(c)
hereof.

     (c)    The Average Price Per Share of ONB common stock shall mean and be
calculated based upon the average of the per share closing prices of ONB common
stock as reported on the National Association of Securities Dealers Automated
Quotation System ("NASDAQ") National Market System for the first five (5)
business days on which trades of shares of ONB common stock are reported on
NASDAQ within the ten (10) calendar days immediately preceding the Effective

                                      A-2
<PAGE>
 
Time ("Average Price Per Share").  The adjustment contemplated by Section
2.01(b) hereof shall be applied in the following manner: (i) if the Average
Price Per Share of ONB common stock exceeds $35.75, then the Exchange Ratio
shall be adjusted such that each share of Carmi Common Stock shall be converted
into the number of shares of ONB common stock resulting from the following
formula: $126.72 / ($32.50 + (Average Price Per Share - $35.75)); (ii) if the
Average Price Per Share of ONB common stock is less than $29.25, then the
Exchange Ratio shall be adjusted such that each share of Carmi Common Stock
shall be converted into the number of shares of ONB common stock resulting from
the following formula: $126.72 / ($32.50 - ($29.25 - Average Price Per Share));
and (iii) if the Average Price Per Share of ONB common stock is not less than
$29.25 nor more than $35.75, then there shall be no adjustment to the Exchange
Ratio.

     (d)    The Exchange Ratio set forth herein and the market values of ONB
common stock referenced in (b) and (c) hereof have been adjusted to reflect the
five percent (5%) stock dividend declared by ONB on December 15, 1995 and
payable on February 20, 1996. No further adjustment therefor shall be made as
provided in Section 2.03 hereof with respect to such stock dividend.

     2.02.  No Fractional Shares.  Certificates for fractional shares of ONB
common stock shall not be issued for fractional interests resulting from
application of the Exchange Ratio.  Each shareholder of Carmi who would
otherwise have been entitled to a fraction of a share of ONB common stock shall
be paid in cash following the Effective Time an amount equal to such fraction
multiplied by the Average Price Per Share of ONB common stock.

     2.03.  Recapitalization.  If, between the date of this Agreement and the
Effective Time, the record date occurs for the distribution or issuance by ONB
of a stock dividend with respect to its shares of common stock, or the
combination, subdivision, reclassification or split of ONB's  issued and
outstanding shares of common stock, such that the number of issued and
outstanding shares of ONB common stock is increased or decreased, then the
Exchange Ratio shall be adjusted so that Carmi's shareholders shall receive, in
the aggregate, such number of shares of ONB common stock representing the same
percentage of outstanding shares of ONB common stock at the Effective Time as
would have been represented by the number of shares such shareholders would have
received if any of the foregoing actions had not occurred.

     2.04.  Distribution of ONB Common Stock and Cash.  (a)  Following the
Effective Time and within twenty (20) days thereof, ONB shall mail to each Carmi
shareholder a letter of transmittal providing instructions as to the transmittal
to ONB of certificates representing shares of Carmi Common Stock and the
issuance of shares of ONB common stock in exchange therefor pursuant to the
terms of this Agreement.

     (b)    Following the Effective Time, distribution of stock certificates
representing shares of ONB common stock and any cash payment, without interest,
for fractional shares, if any, shall be made by ONB to each former shareholder
of Carmi within twenty (20) business days following delivery to ONB of the
shareholder's certificate(s) representing its shares of Carmi Common Stock
accompanied by a properly completed and executed letter of transmittal, all in
form and substance reasonably satisfactory to ONB.

     (c)    Following the Effective Time, stock certificates representing shares
of Carmi Common Stock shall be deemed to evidence ownership of ONB common stock
for all corporate purposes other than the payment of dividends or other
distributions. No dividends or other


                                      A-3
<PAGE>
 
distributions otherwise payable subsequent to the Effective Time on shares of
ONB common stock shall be paid to any Carmi shareholder entitled to receive the
same until such shareholder has surrendered to ONB his or her certificate or
certificates representing Carmi Common Stock in exchange for a certificate or
certificates representing ONB common stock. Upon surrender of the certificates
representing shares of Carmi Common Stock, there shall be paid in cash to the
record holder of the new certificate or certificates evidencing shares of ONB
common stock the amount of all dividends and other distributions, without
interest thereon, withheld with respect to such shares of ONB common stock.

     (d)    ONB shall be entitled to rely upon the stock transfer books of Carmi
to establish the persons entitled to receive shares of ONB common stock pursuant
to this Agreement, which books shall be conclusive with respect to the ownership
of shares of Carmi Common Stock.

     (e)    With respect to any certificate for shares of Carmi Common Stock
which has been lost, stolen or destroyed, ONB shall be authorized to issue
common stock (or to pay cash as to fractional shares) to the registered owner of
such certificate upon receipt by ONB of an agreement to indemnify ONB against
loss from such lost, stolen or destroyed certificate and an affidavit of lost,
stolen or destroyed stock certificate, both in form and substance reasonably
satisfactory to ONB, and upon compliance by the Carmi shareholder with all other
reasonable requirements of ONB in connection with lost, stolen or destroyed
stock certificates.

note or other commitment of Carmi, in excess of $10,000 individually or in the
aggregate, whether in principal, interest or otherwise, and including all
guarantors of such indebtedness.

     (c)    To the best knowledge of Carmi and Insurance Agency after due

material obligation, covenant or provision contained therein. None of the
foregoing requires the consent of any party to its assignment in connection with
the Merger contemplated by this Agreement. Other than as disclosed pursuant to
this Section 4.09, to the best knowledge of Carmi and Insurance Agency after due
inquiry, no circumstances exist resulting from transactions effected or to be

except for unfunded loan commitments and obligations on letters of credit to
customers of Carmi, except for obligations and expenses of Carmi and Insurance
Agency related to the Merger and except for trade payables incurred in the
ordinary course of business, Carmi and Insurance Agency have not, nor will have
at the Effective Time, any obligation, agreement, contract, commitment,
liability, lease or license which exceeds $10,000 individually, or any
obligation, agreement, contract, commitment, liability, lease or license made
outside of the ordinary course of business, nor does there exist any
circumstances resulting from transactions effected or events occurring on or
prior to the date of this Agreement or from any action omitted to be taken
during such period which could reasonably be expected to result in any such
obligation, agreement, contract, commitment, liability, lease or license.

     4.11.  Title to Assets.  Except as described in this Section 4.11:  (a)
Carmi or Insurance Agency, as the case may be, has good and marketable title in

sales contracts, mortgages, liens, pledges, restrictions, security interests,
charges, claims, rights of third parties or encumbrances of any nature except:

reasonable detail in the Carmi Financial Statements; (iii) statutory liens for
taxes not yet delinquent or being contested in good faith by appropriate
proceedings; (iv) pledges or liens required to be granted in connection with the
acceptance of government deposits or granted in connection with repurchase or
reverse repurchase agreements; and (v) easements, encumbrances and liens of
record, imperfections of title and other limitations which are not material in
amounts to Carmi or Insurance Agency and which do not materially detract from
the value or materially interfere with the present or contemplated use of any of
the properties subject thereto or otherwise materially impair the use thereof
for the purposes for which they are held or used. All real property owned or
leased by Carmi or Insurance Agency is in material compliance with all
applicable zoning and land use laws.

     (b)    To the best knowledge of Carmi and Insurance Agency after due
inquiry, each has conducted its business in compliance with all federal, state,
county and municipal laws, statutes, regulations, rules, ordinances, orders,
directives, restrictions and requirements relating to, without limitation,
responsible property transfer, underground storage tanks, petroleum products,
air pollutants, water pollutants or storm water or process waste water or
otherwise relating to the environment or toxic or hazardous substances or to the
manufacturing, recycling, handling, processing, distribution, use, generation,
treatment, storage, disposal or transport of any hazardous or toxic substances
or petroleum products (including polychlorinated biphenyls, whether contained or
uncontained, and asbestos-containing materials, whether friable or not),
including, without limitation, the Federal Solid Waste Disposal Act, the
Hazardous and Solid Waste Amendments, the Federal Clean Air Act, the Federal
Clean Water Act, the Occupational Health and Safety Act, the Federal Resource
Conservation and Recovery Act, the Toxic Substances Control Act, the Federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980 and
the Superfund Amendments and Reauthorization Act of 1986, all as amended, and
regulations of the Environmental Protection Agency, the Nuclear Regulatory
Agency, the Army Corp of Engineers, the Department of Interior, the United
States Fish and Wildlife Service and any state department of natural resources
or state environmental protection agency now or at any time thereafter in effect
(collectively, "Environmental Laws"). There are no pending or, to the best
knowledge of Carmi and Insurance Agency after due inquiry, threatened claims,
actions or proceedings by any local municipality, sewage district or other
governmental entity against Carmi or Insurance Agency with respect to the
Environmental Laws, and, to the best knowledge of Carmi and Insurance Agency
after due inquiry, there is no basis or grounds for any such claim, action or
proceeding. No environmental clearances or other governmental approvals are
required for the conduct of the business of Carmi or Insurance Agency or the
consummation of the Merger contemplated hereby. Except as set forth in the
Disclosure Schedule, to the best of their knowledge after due inquiry, neither
Carmi nor Insurance Agency is the owner, and has not been in the chain of title
or the operator or lessee, of any property on which any substances have been
used, stored, deposited, treated, recycled or disposed of, which substances if
known to be present on, at or under such property would require clean-up,
removal or any other remedial action under any Environmental Law.

     (c)    Neither Carmi nor Insurance Agency: (i) is in default in any respect
under any agreements pursuant to which either leases real or personal property;
(ii) has any knowledge of any



                                      A-11
<PAGE>
 
default under such agreements by any party thereto; and (iii) has any knowledge
of any event which, with notice or lapse of time or both, would constitute such
a default.

     4.12.  Loans and Investments.  (a)  Except as set forth in the Disclosure
Schedule, there is no loan by Carmi in excess of $10,000 that has been
classified by bank regulatory examiners or management of Carmi as "Other Loans
Specially Mentioned," "Substandard," "Doubtful" or "Loss" or in excess of
$10,000 that has been identified by accountants or auditors (internal or
external) as having a significant risk of uncollectability.  The most recent
loan watch list of Carmi and a list of all loans in excess of $10,000 which
Carmi has determined to be thirty (30) days or more past due with respect to
principal or interest payments or has placed on nonaccrual status are set forth
in the Disclosure Schedule.

     (b)    All loans reflected in the Carmi Financial Statements as of December
31, 1995 and which have been made, extended, renewed, restructured, approved,
amended or acquired since December 31, 1995: (i) have been made for good,
valuable and adequate consideration in the ordinary course of business; (ii) to
the best knowledge of Carmi solely with respect to the authenticity of the
signatures of borrowers, obligors and guarantors thereon constitute the legal,
valid and binding obligation of the obligor and any guarantor named therein,
except to the extent limited by general principles of equity and public policy
or by bankruptcy, insolvency, fraudulent transfer, reorganization, liquidation,
moratorium, readjustment of debt or other laws of general application relative
to or affecting the enforcement of creditors' rights; (iii) are evidenced by
notes, instruments or other evidences of indebtedness which are true, genuine
and what they purport to be; and (iv) are secured, to the extent that Carmi has
a security interest in collateral or a mortgage securing such loans, by
perfected security interests or recorded mortgages naming Carmi as the secured
party or mortgagee.

     (c)    The reserves, the allowance for possible loan and lease losses and
the carrying value for real estate owned which are shown on the Carmi Financial
Statements are adequate in all material respects under the requirements of
generally accepted accounting principles applied on a consistent basis to
provide for possible losses on items for which reserves were made, on loans and
leases outstanding and real estate owned as of the respective dates. To the best
knowledge of Carmi after due inquiry, the aggregate loan balances outstanding as
of December 31, 1995 in excess of the reserve for loan losses as of such date
are collectible in accordance with their respective terms.

     (d)    Subject to the restrictions of Statement of Financial Accounting
Standards No. 115, none of the investments reflected in the Carmi Financial
Statements as of and for the period ended December 31, 1995 and none of the
investments made by Carmi since December 31, 1995 are subject to any
restriction, whether contractual or statutory, which materially impairs the
ability of Carmi to dispose freely of such investment at any time. Carmi is not
a party to any repurchase agreements with respect to securities.

     (e)    Set forth in the Disclosure Schedule is a true, accurate and
complete list of all loans in which Carmi has any participation interest or
which have been made with or through another financial institution on a recourse
basis against Carmi.

     (f)    Except as set forth in the Disclosure Schedule, and except for
customer deposits and ordinary trade payables, neither Carmi nor Insurance
Agency has, nor will have at the Effective Time, any indebtedness for borrowed
money.

Revenue Service ("Service") with respect to each such Carmi Plan stating that
each, in its current form (or at the time of its disposition if it has been
terminated, merged, frozen or discontinued), is qualified under and satisfies
all applicable provisions of the Code and Treasury Regulations; (iii) except as
set forth on the Disclosure Schedule, no Carmi Plan (or its related trust) holds
any stock or other securities of Carmi or any related or affiliated person or
entity; (iv) neither Carmi nor Insurance Agency has any liability to the
Department or the Service with respect to any Carmi Plan; (v) neither Carmi nor

of ERISA; (vi) no prohibited transaction (as defined in Section 406 of ERISA and
as defined in Section 4975(c) of the Code) has occurred with respect to any
Carmi Plan; (vii) each Carmi Plan subject to ERISA or intended to be qualified

in all material respects in accordance with the applicable provisions of ERISA

denied any benefit due or to become due under any Carmi Plan or has been misled
as to his or her rights under any Carmi Plan; (ix) all obligations required to

them in all material respects and they are not in default under or in violation
of in any material respect any provision of a Carmi Plan; (x) no event has, to

reporting and disclosure requirements of ERISA or the Code, there has been, to
the best knowledge of Carmi and Insurance Agency after due inquiry, no violation
of the reporting and disclosure requirements imposed either under ERISA or the
Code for which a penalty has been or may be imposed.

     (b)    With regard to any Carmi Plan intended to be qualified under Section
401(a) of the Code, no director, officer, employee or agent of Carmi or
Insurance Agency has engaged in any action or failed to act in such a manner
that, as a result of such action or failure to act, the Service could revoke or

                     REPRESENTATIONS AND WARRANTIES OF ONB
                     -------------------------------------

     ONB represents and warrants to Carmi with respect to itself and, at the
time it is formed and becomes a party to this Agreement, with respect to Merger
Bank as follows:

     5.01.  Organization and Authority.  (a)  ONB is a corporation duly
organized and validly existing under the laws of the State of Indiana, is a
registered bank holding company under the BHC Act, and has full power and
authority (corporate and otherwise) to own and lease its properties as presently
owned and leased and to conduct its business in the manner and by the means
utilized as of the date hereof.  ONB's common stock is registered pursuant to
Section 12, and ONB is subject to the reporting requirements, of the 1934 Act.

     (b)    As of the Effective Time, Merger Bank shall be a national banking
association duly organized and validly existing under the laws of the United
States of America, and all of its issued and outstanding capital stock will be
owned by ONB.

     5.02.  Authorization.  (a)  Each of ONB and Merger Bank has the requisite
corporate power and authority to enter into this Agreement and to carry out its
obligations hereunder, subject to the fulfillment of the conditions precedent
set forth in Section 8.01 hereof.  This Agreement and its execution and delivery
by ONB have been duly authorized by the Board of Directors of ONB and, at or
prior to the Effective Time, the First Amendment and its execution and delivery
by Merger Bank shall have been duly authorized by the Board of Directors of
Merger Bank.  This Agreement constitutes a valid and binding obligation of ONB
and, upon execution of the First Amendment, of Merger Bank, subject to the
conditions precedent set forth in Section 8.01 hereof, and is enforceable in
accordance with its terms, except to the extent limited by general principles of
equity and public policy and by bankruptcy, insolvency, reorganization,
liquidation, moratorium, readjustment of debt or other laws of general
application relating to or affecting the enforcement of creditors' rights.

     (b)    Neither the execution of this Agreement nor consummation of the
Merger contemplated hereby: (i) conflicts with or violates ONB's Articles of
Incorporation or By-Laws or Merger Bank's Articles of Association or By-Laws
(when organized); (ii) conflicts with or violates in any material respect any
local, state, federal or foreign law, statute, ordinance, rule or regulation
(provided that the approvals of or filings with applicable government regulatory
agencies or authorities required for consummation of the Merger are obtained) or
any court or administrative judgment, order, injunction, writ or decree; or
(iii) conflicts with, results in a breach of or constitutes a material default
under any note, bond, indenture, mortgage, deed of trust, license, contract,
lease, agreement, arrangement, commitment or other instrument to which ONB is or
Merger Bank will be a party or by which ONB is or Merger Bank will be subject or
bound and which is material to ONB on a consolidated basis.

     (c)    Other than in connection or in compliance with applicable federal
and state banking, securities and corporation statutes, all as amended, and the
rules and regulations promulgated thereunder, no notice to, filing with,
exemption by or consent, authorization or approval of any



                                      A-19
<PAGE>
 
governmental agency or body is necessary for the consummation by ONB and Merger
Bank of the Merger contemplated by this Agreement.

     5.03.  Capitalization.  (a) The authorized capital stock of ONB as of the
date hereof consists of (i) 30,000,000 shares of common stock, no par value per
share, of which approximately 25,370,000 shares were issued and outstanding as
of December 31, 1995, and (ii) 2,000,000 shares of preferred stock, no shares of
which have been or are presently intended to be issued, other than in connection
with any obligations of ONB to issue such preferred stock under its
shareholders' rights plan.  Such issued and outstanding shares of ONB capital
stock have been duly and validly authorized by all necessary corporate action of
ONB, are validly issued, fully paid and nonassessable, and have not been issued
in violation of any pre-emptive rights of any present or former ONB
shareholders.  All of the issued and outstanding shares of common stock of ONB's
subsidiaries are owned by ONB free and clear of all liens, pledges, charges,
claims, encumbrances, restrictions, security interests, options and pre-emptive
rights and of all other rights or claims of any other person, corporation or
entity with respect thereto.  Except as described in this Section 5.03, ONB has
no other authorized capital stock.  Except for shares of ONB common stock to be
issued in connection with:  (i) ONB's dividend reinvestment and stock purchase
plan; (ii) ONB's outstanding convertible subordinated debentures; (iii)
acquisitions by ONB of other financial institutions or holding companies; and
(iv) ONB's restricted stock plan and other employee benefit plans, ONB has no
intention or obligation to authorize or issue any other capital stock or any
additional shares of ONB capital stock.  On a consolidated basis as of December
31, 1995, ONB had total shareholders' equity of approximately $428,077,000,
which consisted of common stock of $24,955,000, capital surplus of $245,420,000,
retained earnings of $147,367,000, and net unrealized gain on available-for-sale
securities of $10,335,000.

     (b)    ONB has no knowledge of any person who beneficially owns 5% or more
of its issued and outstanding shares of common stock.

     5.04.  Organizational Documents.  The Articles of Incorporation and By-Laws
of ONB in force as of the date of this Agreement have been delivered to Carmi
and represent true, accurate and complete copies of such corporate documents of
ONB in effect as of the date of this Agreement.

     5.05.  Compliance With Law.  Neither ONB nor any of its subsidiaries has
engaged in any activity or has taken or omitted to take any action which has
resulted or could result in the violation of any local, state, federal or
foreign law, statute, rule, regulation, ordinance, order, restriction or
requirement or of any order, injunction, judgment, writ or decree of any court
or government agency or body, the violation of which could have a material
adverse effect on the financial condition, results of operations, business,
assets or capitalization of ONB and its subsidiaries on a consolidated basis.
ONB and each of its subsidiaries possesses and holds all licenses, franchises,
permits, certificates and other authorizations necessary for the continued
conduct of their business without interference or interruption.

     5.06.  Regulatory Filings.  ONB and each of its subsidiaries have filed and
will continue to file in a timely manner all required filings with the
Securities and Exchange Commission ("SEC"), including, but not limited to, all
reports on Form 8, Form 8-K, Form 10-K and Form 10-Q and proxy statements, and
with all other federal and state regulatory agencies as required by applicable
law.  All filings by ONB with the SEC and with all other federal and state
regulatory 

                                      A-20
<PAGE>
 
agencies were true, accurate and complete in all material respects as of the
dates of the filings, and no such filings contained any untrue statement of a
material fact or omitted to state a material fact necessary in order to make the
statements, at the time and in the light of the circumstances under which they
were made, not false or misleading.

     5.07.  Litigation and Pending Proceedings.  (a) There are no claims,
actions, suits, proceedings, investigations or arbitrations pending or, to the
best knowledge of ONB after due inquiry, threatened in any court or before any
government agency or authority, arbitration panel or otherwise (nor does ONB
have any knowledge of a basis for any claim, action, suit, proceeding,
litigation, investigation or arbitration) against, by or affecting ONB or its
subsidiaries which would reasonably be expected to have a material adverse
effect on the financial condition, results of operations, business, assets or
capitalization of ONB and its subsidiaries on a consolidated basis, or which
would prevent the performance of this Agreement, declare the same unlawful or
cause the rescission hereof.

     (b)    Pending Proceedings. Neither ONB nor any of its subsidiaries is: (i)
subject to any outstanding judgment, order, writ, injunction or decree of any
court, arbitration panel or governmental agency or authority having a material
adverse effect on the financial condition, results of operations, business,
assets or capitalization of ONB on a consolidated basis; (ii) presently charged
with or, to the best knowledge of ONB, under governmental investigation with
respect to any actual or alleged violations of any law, statute, rule,
regulation or ordinance, the violation of which could have a material adverse
effect on the financial condition, results of operation, business, assets or
capitalization of ONB on a consolidated basis; or (iii) the subject of any
pending or, to the best knowledge of ONB after due inquiry, threatened
proceeding by any government regulatory agency or authority having jurisdiction
over its business, assets, capital, properties or operations, the violation of
which could have a material adverse effect on the financial condition, results
of operations, business, assets or capitalization of ONB on a consolidated
basis.

     5.08.  Financial Statements and Reports.  (a) ONB or its agents have
delivered to Carmi copies of the following financial statements and reports of
ONB and its subsidiaries (collectively, the "ONB Financial Statements"):

     (i)    Consolidated Balance Sheets and related Consolidated Statements of
            Income and Consolidated Statements of Changes in Shareholders'
            Equity of ONB as of and for the years ended December 31, 1993, 1994
            and 1995; and

     (ii)   Consolidated Statements of Cash Flows of ONB for the years ended
            December 31, 1993, 1994 and 1995.

     (b)    The ONB Financial Statements are true, accurate and complete in all
material respects and present fairly the consolidated financial positions of ONB
and its subsidiaries as of and at the dates shown and the consolidated results
of operations for the periods covered thereby. The ONB Financial Statements
described in clauses (i) and (ii) above which consist of fiscal year-end
information are audited financial statements and have been prepared in
conformance with generally accepted accounting principles applied on a
consistent basis except as may otherwise be indicated in any accountants' notes
or reports with respect to such financial statements. The ONB Financial
Statements do not include any assets, liabilities or obligations or omit to
state any assets,


                                      A-21
<PAGE>
 
liabilities or obligations, absolute or contingent, or any other facts, which
inclusion or omission would render the ONB Financial Statements false,
misleading or inaccurate in any material respect.

     5.09.  Shares to be Issued in Merger.  The shares of ONB common stock which
Carmi shareholders will be entitled to receive upon consummation of the Merger
pursuant to this Agreement will, at the Effective Time, be duly authorized and
will, when issued in accordance with this Agreement, be validly issued, fully
paid and nonassessable and will have been registered under the Securities Act of
1933, as amended ("1933 Act") and listed for trading on the NASDAQ National
Market System.

     5.10.  Shareholder Approval.  The approval by ONB's shareholders of the
Merger or any other actions contemplated by this Agreement is not required.

     5.11.  Accuracy of Statements Made to Carmi.  No representation, warranty
or other statement made, or any information provided, by ONB in this Agreement,
and no written report, statement, list, certificate, materials or other
information furnished or to be furnished by ONB to Carmi through and including
the Effective Time in connection with this Agreement or the Merger contemplated
hereby (including, without limitation, any written information which has been or
shall be supplied by ONB with respect to its financial condition, results of
operations, business, assets, capital or directors and officers for inclusion in
the proxy statement-prospectus and registration statement relating to the
Merger), contains or shall contain (in the case of information relating to the
proxy statement-prospectus at the time it is mailed to Carmi's shareholders) any
untrue or misleading statement of material fact or omits or shall omit to state
a material fact necessary to make the statements contained herein or therein, in
light of the circumstances in which they are made, not false or misleading.

     5.12.  Contracts.  ONB and each of its subsidiaries has performed in all
material respects all obligations required to be performed by them under all
agreements which are material to ONB on a consolidated basis, and neither ONB
nor any of its subsidiaries, to the best knowledge of ONB, is in default under
or in breach of, in any material respect, any agreement which is material to ONB
on a consolidated basis.

     5.13.  Environmental Compliance.  To the best knowledge of ONB after
reasonable inquiry, ONB and its subsidiaries have conducted their respective
businesses in material compliance with the Environmental Laws.

     5.14.  Regulatory Approvals.  To the best knowledge of ONB after reasonable
inquiry, there currently exists no reason why the granting of any of the state
or federal regulatory approvals required for consummation of the Merger would
reasonably be expected to be denied or unduly delayed.

     5.15.  Representations and Warranties at the Effective Date.  All
representations and warranties of ONB contained herein shall be true, accurate
and complete in all material respects on and as of the Effective Time as though
made or given at such time.

     5.16.  Nonsurvival of Representations and Warranties.  The representations
and warranties of ONB contained in this Agreement shall expire at the Effective
Time and, thereafter, ONB and all directors, officers and employees of ONB shall
have no further liability with respect thereto,

except for fraud or for false or misleading statements made intentionally or
knowingly in connection with such representations and warranties or except as
otherwise provided by law, whether statutory, common law or otherwise.

and until the Effective Time or until this Agreement shall be terminated as
herein provided, each of Carmi and Insurance Agency shall not, without the prior
written consent of ONB:

          (i)      make any changes in its capital stock accounts (including,

                   recapitalization or reclassification);

          (ii)     authorize a class of stock or issue, or authorize the

                   dividends which in the aggregate shall not



                                      A-23
<PAGE>
 
                   exceed Carmi's undivided profits (calculated in accordance

                   however, that if Carmi's shareholders become entitled to
                   receive a cash dividend from ONB for the calendar quarter
                   during which the Merger is consummated, then the aggregate
                   cash dividends permitted to be paid by Carmi to its
                   shareholders shall be reduced by the aggregate cash dividend
                   for such quarter receivable by Carmi's shareholders from ONB,
                   and if the amount of such dividend from ONB is not yet
                   determinable, such amount shall be calculated based upon the
                   per share amount of the last cash dividend paid by ONB to its

                   practices (and, with respect to loan transactions or
                   commitments, letters of credit and deposit accounts, only on
                   terms and conditions which are not materially more favorable
                   than those available to the borrower or customer from
                   competitive sources in transactions in the ordinary course of
                   business);

maintained, in full force and effect, insurance on its assets, properties and

     6.05.  Restrictions Regarding Affiliates.  Carmi shall, within thirty (30)
days after the date of this Agreement and promptly thereafter until the
Effective Time to reflect any changes, provide ONB with a list identifying each
person who may be deemed to be an affiliate of Carmi for purposes of Rule 145
under the 1933 Act.  On or prior to the date of this Agreement, Carmi shall use
its best efforts to cause each director, executive officer and other person who
may be deemed to be such an affiliate of Carmi to deliver to ONB on or prior to
the date of this Agreement a written agreement, substantially in the form as
attached hereto as Exhibit B, providing that such person:  (a) shall not sell,
pledge, transfer, dispose of or otherwise reduce his or her market risk with
respect to the shares of Carmi Common Stock directly or indirectly owned or held
by such person during the thirty (30) day period prior to the Effective Time;
and (b) will not sell, pledge, transfer, dispose of or otherwise reduce his or
her market risk with respect to the shares of ONB common stock to be received by
such person pursuant to this Agreement:  (i) until such time as financial
results covering at least 30 days of combined operations of ONB and Carmi have
been published as and when required and within the meaning of Section 201.01 of
the SEC's Codification of Financial Reporting Policies; and (ii) unless such
sales are pursuant to an effective Registration Statement under the 1933 Act or
pursuant to Rule 145 under the 1933 Act or another exemption from registration
under the 1933 Act.

     6.06.  Other Negotiations.  (a)  Subject to Section 6.06(b) hereof, on and
after the date of this Agreement and until the Effective Time or until this
Agreement is terminated as herein provided, except with the prior written
approval of ONB, Carmi and Insurance Agency shall not, and shall not permit or
authorize their respective directors, officers, employees, agents or
representatives to, directly or indirectly, initiate, solicit, encourage or
engage in discussions or negotiations with, or provide information to, any
corporation, association, partnership, person or other entity or group
concerning any merger, consolidation, share exchange, combination, purchase or
sale of substantial assets, sale of shares of common stock (or securities
convertible or exchangeable into or otherwise evidencing, or any agreement or
instrument evidencing the right to acquire, capital stock) or similar
transaction relating to Carmi or Insurance Agency or to which Carmi or Insurance
Agency may become a party (all such transactions are hereinafter referred to as
"Acquisition Transactions").  Carmi and Insurance Agency shall promptly
communicate to ONB the terms of any proposal or offer which either of them may
receive with respect to an Acquisition Transaction and any request by or
indication of interest on the part of any third party with respect to the
initiation of any Acquisition Transaction or discussions with respect thereto.

     (b)    On and after the date of this Agreement and until the Effective Time
or until this Agreement is terminated as provided herein, Carmi may engage, and
may permit and authorize their respective directors, officers, employees, agents
or representatives to, directly or indirectly, engage in discussions or
negotiations with, or provide information to, any corporation, association,
partnership, person or other entity or group concerning an unsolicited offer by
such third party with respect to an Acquisition Transaction only with the prior
written approval of ONB, which approval shall be provided to Carmi promptly upon
receipt by ONB of a letter from Carmi signed by at least a majority of its Board
of Directors then in office indicating that Carmi has received an unsolicited

                                      A-27
<PAGE>
 
offer regarding an Acquisition Transaction which the Board of Directors of
Carmi: (i) considers, in the exercise of its fiduciary duties as a Board, to be
substantially superior to the then current offer of ONB pursuant to this
Agreement; and (ii) concludes, after consultation with its counsel, that its
fiduciary duties as a Board require it to consider and, in light of such duties,
take such other actions with respect to such unsolicited offer as may be
necessary or appropriate; and such approval may, in all other instances, be
provided to Carmi when and if ONB shall, in its sole discretion, determine. This
Section 6.06 shall not authorize Carmi, or its directors, officers, employees,
agents or representatives, to initiate any discussions or negotiations relative
to an Acquisition Transaction with a third party.

     6.07.  Press Releases.  Except as required by law, Carmi and Insurance
Agency shall not issue any press releases or make any other public announcements
or disclosures relating to the Merger without the prior consent of ONB, which
consent shall not be unreasonably withheld.

     6.08.  Disclosure Schedule Update.  Carmi shall promptly supplement, amend
and update, upon the occurrence of any change prior to the Effective Time, and
as of the Effective Time, the Disclosure Schedule with respect to any matters or
events hereafter arising which, if in existence or having occurred as of the
date of this Agreement, would have been required to be set forth or described in
the Disclosure Schedule or this Agreement and including, without limitation, any
fact which, if existing or known as of the date hereof, would have made any of
the representations or warranties of Carmi or Insurance Agency contained herein
materially incorrect, untrue or misleading.

     6.09.  Information, Access Thereto, Confidentiality.  ONB and its
respective representatives and agents shall, at all times during normal business
hours prior to the Effective Time, have full and continuing access to the
properties, facilities, operations, books and records of Carmi and Insurance
Agency.  ONB and its respective representatives and agents may, prior to the
Effective Time, make or cause to be made such reasonable investigation of the
operations, books, records and properties of Carmi and Insurance Agency and of
their financial and legal condition as deemed necessary or advisable to
familiarize themselves with such operations, books, records, properties and
other matters; provided, however, that such access or investigation shall not
interfere unnecessarily with the normal operations of Carmi and Insurance
Agency.  Upon request, Carmi and Insurance Agency shall furnish ONB or its
respective representatives or agents, their attorneys' responses to external
auditors requests for information, management letters received from their
external auditors and such financial, loan and operating data and other
information reasonably requested by ONB which has been or is developed by Carmi
or Insurance Agency, their auditors, accountants or attorneys (provided with
respect to attorneys, such disclosure would not result in the waiver by Carmi or
Insurance Agency of any claim of attorney-client privilege), and will permit ONB
and its respective representatives or agents to discuss such information
directly with any individual or firm performing auditing or accounting functions
for Carmi or Insurance Agency, and such auditors and accountants shall be
directed to furnish copies of any reports or financial information as developed
to ONB or its respective representatives or agents.  No investigation by ONB
shall affect the representations and warranties made by Carmi or Insurance
Agency herein.  Any confidential information or trade secrets received by ONB or
its representatives or agents in the course of such examination shall be treated
confidentially, and any correspondence, memoranda, records, copies, documents
and electronic or other media of any kind containing such confidential
information or trade secrets or both shall be destroyed by ONB or, at Carmi's
request, returned to Carmi in the event this Agreement is terminated as provided
in Section 9 hereof.  This 

                                      A-28
<PAGE>
 
Section 6.09 shall not require the disclosure of any information to ONB which
would be prohibited by law.

     6.10.  Subsequent Carmi Financial Statements.  As soon as reasonably
available after the date of this Agreement, Carmi shall deliver to ONB the
monthly unaudited consolidated balance sheets and profit and loss statements of
Carmi prepared for its internal use, Carmi's Call Reports for each quarterly
period completed prior to the Effective Time and all other financial reports or
statements submitted to regulatory authorities after the date hereof, to the
extent permitted by law (collectively, "Subsequent Carmi Financial Statements").
The Subsequent Carmi Financial Statements shall be prepared on a basis
consistent with past accounting practices and generally accepted accounting
principles applied on a consistent basis to the extent applicable and shall
present fairly the financial condition and results of operations as of the dates
and for the periods presented.  The Subsequent Carmi Financial Statements,
including the notes thereto, will not include any assets, liabilities or
obligations or omit to state any assets, liabilities or obligations, absolute or
contingent, or any other facts, which inclusion or omission would render such
financial statements inaccurate, incomplete or misleading in any respect.

     6.11. Employee Benefits. Neither the terms of Section 7.03 hereof nor the
provision of any employee benefits by ONB or any of its subsidiaries to
employees of Carmi shall: (a) create any employment contract, agreement or
understanding with or employment rights for, or constitute a commitment or
obligation of employment to, any of the officers or employees of Carmi; or (b)
prohibit or restrict ONB or its subsidiaries, whether before or after the
Effective Time, from changing, amending or terminating any employee benefits
provided to its employees from time to time.

                                      A-29
<PAGE>
 
     7.02.  SEC Registration.  ONB shall file with the SEC as soon as
practicable after the execution of this Agreement a Registration Statement on an
appropriate form under the 1933 Act covering the shares of ONB common stock to
be issued pursuant to this Agreement and shall use its best efforts to cause the
same to become effective and thereafter, until the Effective Time or termination
of this Agreement, to keep the same effective and, if necessary, amend and
supplement the same.  Such Registration Statement and any amendments and
supplements thereto are referred to in this Agreement as the "Registration
Statement".  The Registration Statement shall include a proxy statement-
prospectus reasonably acceptable to ONB and Carmi, prepared for use in
connection with the meeting of shareholders of Carmi referred to in Section 6.01
of this Agreement, all in accordance with the rules and regulations of the SEC
and the OCC.  ONB shall, as soon as practicable after filing the Registration
Statement, make all filings required to obtain all Blue Sky exemptions,
authorizations, consents or approvals required for the issuance of ONB common
stock.  In advance of filing the Registration Statement and all other filings
described in Section 7.01 herein, ONB shall provide Carmi and its counsel with a
copy of the Registration Statement and each such other filing and provide an
opportunity to comment thereon.

     7.03.  Employee Benefit Plans.  (a) At such time as ONB shall determine, in
its sole discretion, but in no event later than January 1, 1997, ONB will make
available to the employees of Carmi who continue as employees of any subsidiary
of ONB after the Effective Time and, further, subject to Section 7.03(b), (c)
and (d) hereof, substantially the same employee benefits on substantially the
same terms and conditions that ONB may offer to similarly situated officers and
employees of its banking subsidiaries from time to time.  Until such time as the
employees of Carmi become covered by the ONB welfare benefit plans, the
employees of Carmi shall remain covered by the welfare benefit plans sponsored
by Carmi, subject to the terms of such plans.

     (b)    Subject to the provisions of subsection (c) hereof, years of service
(as defined in the applicable ONB plan) of an officer or employee of Carmi prior
to the Effective Time shall be credited, effective as of the date on which such
employees become covered by a particular ONB plan, to each such officer or
employee eligible for coverage under Section 7.03(a) hereof for purposes of: (i)
eligibility under ONB's employee welfare benefit plans; and (ii) eligibility and
vesting, but not for purposes of benefit accrual or contributions, under the ONB
Employees' Retirement Plan ("ONB Pension Plan") or under the ONB Employees'
Savings and Profit Sharing Plan ("ONB Profit Sharing Plan"). Those officers and
employees of Carmi who otherwise meet the eligibility requirements of the ONB
Pension Plan and the ONB Profit Sharing Plan, based upon their age and years of
Carmi service, shall become participants thereunder on the January 1st which
coincides with or next follows the Effective Time. Those officers or employees
who do not meet the eligibility requirements of the ONB Pension Plan or ONB
Profit Sharing Plan on such date shall become participants thereunder on the
first plan entry date under the ONB Pension Plan or the ONB Profit Sharing Plan,
as the case may be, which coincides with or next follows the date on which such
eligibility requirements are satisfied.

     (c)    Subject to the requirements and limitations of applicable law, ONB
shall take or cause to be taken the following actions regarding the disposition
of the following Carmi Plans:

          (i)   The Carmi defined contribution plan with the "401(k)" feature
                ("401(k) Plan"), and all assets and liabilities associated
                therewith, shall be merged with and into the ONB Profit Sharing
                Plan.  Such merger shall be effective as of the December 31
                which coincides with or immediately follows the 

                                      A-30
<PAGE>
 
                Effective Time. Until the effective date of such merger,
                eligible participants under the 401(k) Plan may continue to make
                salary deferral contributions thereunder, subject to the terms
                of such plan; and, Carmi may continue to make contributions
                under such plan at substantially the same levels and at
                substantially the same times as Carmi has historically
                contributed to the 401(k) Plan. On the Effective Date, all
                participants under the 401(k) Plan (and any Carmi employees who
                become participants under the 401(k) Plan after the Effective
                Time but before the merger of such plan with and into the ONB
                Profit Sharing Plan) shall become fully vested in their account
                balances regardless of their vested position under the 401(k)
                Plan.

          (ii)  All expenses and costs associated with the disposition of all
                Carmi Plans in connection with the Merger, if any, shall be
                paid by Carmi.

     (d) No full-time officer or employee of Carmi serving as of the Effective
Time shall be subject to any pre-existing condition exclusions under any of
ONB's welfare benefit plans if such officer, employee or individual was covered
by the corresponding Carmi welfare benefit plan for more than two hundred
seventy (270) days immediately preceding the Effective Time.

     (e) Neither the terms of this Section 7.03 nor the provision of any
employee benefits by ONB or any of its subsidiaries to employees of Carmi shall:
(i) create any employment contract, agreement or understanding with or
employment rights for, or constitute a commitment or obligation of employment
to, any of the officers or employees of Carmi; or (ii) prohibit or restrict ONB
or its subsidiaries, whether before or after the Effective Time, from changing,
amending or terminating any employee benefits provided to its employees from
time to time.

     7.04.  Authorization of ONB Common Stock.  The Board of Directors of ONB
shall, prior to the Effective Time, authorize the issuance of the required
number of shares of ONB common stock to be issued pursuant to this Agreement and
take all other necessary corporate action to consummate the Merger contemplated
hereby.

     7.05 Press Releases.  Except as required by law, ONB shall not issue any
press releases or make any other public announcements or disclosures relating
primarily to Carmi or Insurance Agency with respect to the Merger without the
prior consent of Carmi, which consent shall not be unreasonably withheld.

     7.06.  Information, Access Thereto, Confidentiality.  Carmi and its
representatives and agents shall, at all times during normal business hours
prior to the Effective Time, have full and continuing access to the material
facilities, operations, books, records and properties of ONB.  Carmi and its
respective representatives and agents may, prior to the Effective Time, make or
cause to be made such reasonable investigation of the material operations,
books, records and properties of ONB and of its financial and legal condition as
Carmi shall deem reasonable necessary or advisable to familiarize itself with
such books, records, properties and other matters; provided, however, that such
access or investigation shall not interfere unnecessarily with the normal
operations of ONB.  No investigation by Carmi shall affect the representations
and warranties made by ONB.  Any confidential information or trade secrets
received by Carmi or its respective employees or agents in the course of such
examination shall be treated confidentially, and any correspondence, memoranda,
records, copies, documents and electronic or other media of any kind 
  
                                      A-31
<PAGE>
 
containing such confidential information or trade secrets or both shall be
destroyed by Carmi or, at ONB's request, returned to ONB in the event this
Agreement is terminated as provided in Section 9 hereof. This Section 7.06 shall
not require the disclosure of any information to Carmi the disclosure of which
would be prohibited by law.

     7.07.  Name.  It is ONB's intent as of the date of this Agreement and will
be its intent as of the Effective Time that following the Effective Time the
Surviving Bank shall operate under the name "The National Bank of Carmi."
Nothing in this Section 7.07 shall prohibit or restrict ONB or the Board of
Directors of the Surviving Bank from altering, changing or amending the name of
the Surviving Bank after the Effective Time.

     7.08.  Indemnification and Insurance.  (a) Indemnification.  From and after
the Effective Time, ONB shall cause the Surviving Bank and Insurance Agency to
assume and honor any obligations as provided for and permitted by applicable
federal and state law which Carmi and Insurance Agency had immediately prior to
the Effective Time with respect to the indemnification of each person who is on
the date hereof, or has been at any time prior to the date hereof or who becomes
prior to the Effective Time, a director or officer of Carmi or Insurance Agency
or was serving at the request of Carmi or Insurance Agency as a director or
officer of any domestic or foreign corporation, joint venture, trust, employee
benefit plan or other enterprise (collectively, the "Indemnitees") arising out
of Carmi's Articles of Association or By-Laws or Insurance Agency's Certificate
of Incorporation or By-Laws in effect at the Effective Time against any and all
losses in connection with or arising out of any claim which is based upon,
arises out of or in any way relates to any actual or alleged act or omission
occurring at or prior to the Effective Time in the Indemnitee's capacity as a
director or officer (whether elected or appointed), of Carmi or Insurance
Agency.  Indemnification of officers and directors of the surviving Bank and
Insurance Agency following the Effective Time will be provided to the same
extent it is provided from time to time to other persons working in similar
capacities for ONB or its subsidiaries following the Effective Time.

     (b) Insurance.  For a period of one (1) year after the Effective Time, ONB
shall use all reasonable efforts to cause to be maintained in effect the current
policies of directors' and officers' liability insurance maintained by Carmi
(provided that ONB may substitute therefor policies of at least the same
coverage and amounts containing terms and conditions which are substantially no
less advantageous) with respect to claims arising from facts or events which
occurred before the Effective Time.  Following the Effective Time, ONB will
provide any Carmi employees who become officers of ONB or any of its
subsidiaries with the same directors' and officers' liability insurance coverage
that ONB provides to other similarly situated directors and officers of ONB and
its bank subsidiaries.

     7.09.  Employment Agreement.  Following the Effective Time, ONB agrees to
assume and abide by the terms of the Employment Agreement, in the form which has
been included in the Disclosure Schedule, except as may be otherwise required by
law or any government regulatory agency or authority.

                 agree to terminate this Agreement.

     (b)  By ONB, if:

          (i)    the Merger will not qualify for pooling-of-interest accounting
                 treatment for ONB and such failure to qualify is the result of

                 officers or shareholders other than as permitted hereunder;

          (ii)   any item, event or information set forth in any supplement,
                 amendment or update to the Disclosure Schedule has had or would
                 be expected to have, in the reasonable discretion of ONB, a
                 material adverse effect on the business, assets,
                 capitalization, financial condition or results of operations of
                 Carmi and Insurance Agency, on a consolidated basis;

                 relative to the number of issued and outstanding shares of
                 capital stock of Carmi, ONB shall have the absolute right to
                 terminate this Agreement without regard to the materiality of
                 any such inaccuracy;

          (iv)   there has been a breach of or failure to comply with any

          (v)    it shall reasonably determine that the Merger contemplated by

                 proceeding against ONB, Carmi, Insurance Agency or any
                 subsidiary of ONB, or any director or officer of any of such
                 entities (A) relating to this Agreement or the Merger or (B)
                 which is likely to have a material adverse effect on the

                 by or on the part of ONB in its representations and warranties
                 set forth in this Agreement which has had or would be expected
                 to have, in the reasonable discretion of Carmi, a material

                                       TO
                      AGREEMENT OF AFFILIATION AND MERGER


     THIS FIRST AMENDMENT TO AGREEMENT OF AFFILIATION AND MERGER ("Amendment")
is made and entered into as of the 9th day of April, 1996, by and among OLD
NATIONAL BANCORP ("ONB"), THE NATIONAL BANK OF CARMI ("Carmi"), and CARMI MERGER
BANK, N.A. ("Merger Bank").

     WHEREAS, ONB and Carmi are parties to that certain Agreement of Affiliation
and Merger dated March 15, 1996 ("Agreement"); and

     WHEREAS, the Agreement contemplates that Merger Bank, upon its formation,
shall become a party thereto; and

     WHEREAS, Merger Bank has been formed and desires to become a party to the
Agreement; and

     WHEREAS, ONB and Carmi have previously authorized and approved this
Amendment to cause Merger Bank to become a party to the Agreement.

    NOW, THEREFORE, in consideration of the premises, the mutual
representations, warranties, covenants and undertakings contained in the
Agreement, and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto hereby agree as
follows:

    1.    Upon the execution of this Amendment by all of the parties hereto,
Merger Bank shall become a party to the Agreement, having all rights and
obligations granted to or imposed upon it therein.

    2.    The parties hereto shall have the right to restate the Agreement to
reflect the provisions set forth in this Amendment upon the due execution
hereof.

    3.    Upon execution of this Amendment by all of the parties hereto, the
Agreement, as amended hereby, shall constitute a plan of reorganization and a
plan of merger pursuant to the provisions of 12 U.S.C. (S)215, as amended.

    4.    This Amendment shall not amend, modify or supplement the terms,
conditions or provisions of the Agreement, the terms and provisions of which are
incorporated by reference herein, except as expressly provided herein and agreed
upon by the parties hereto.  ONB, Carmi and Merger Bank agree that, except as
expressly provided herein, all of the representations, warranties, covenants and
provisions of the Agreement shall remain and continue in full force and effect
in accordance with their original terms.

    5.    Merger Bank represents and warrants to Carmi that its authorized
shares of capital stock at the Effective Time (as defined in the Agreement) will
consist of 20,000 shares of common stock, $5.00 par value per share, all of

issued and outstanding shares are referred to herein as "Merger Bank Common
Stock"). Such issued and outstanding shares of Merger Bank Common Stock will
have been duly and validly authorized by all necessary corporate action of
Merger Bank, will be validly issued, fully paid and nonassessable (except to the
extent provided by 12 U.S.C. (S)55, as amended), and will not have been issued
in violation of any pre-emptive rights of any present or former Merger Bank
shareholder. Merger Bank has no common stock authorized, issued or outstanding
other than as described in this Section 5 and has no intention or obligation to
authorize or issue any other capital stock or any additional shares of Merger

(S) 215A. MERGER OF NATIONAL BANKS OR STATE BANKS INTO NATIONAL BANKS

(B)  DISSENTING SHAREHOLDERS

     If a merger shall be voted for at the called meetings by the necessary
majorities of the shareholders of each association or State bank participating
in the plan of merger, and thereafter the merger shall be approved by the
Comptroller, any shareholder of any association or State bank to be merged into
the receiving association who has voted against such merger at the meeting of
the association or bank of which he is a stockholder, or has given notice in
writing at or prior to such meeting to the presiding officer that he dissents
from the plan of merger, shall be entitled to receive the value of the shares so
held by him when such merger shall be approved by the Comptroller upon written
request made to the receiving association at any time before thirty days after
the date of consummation of the merger, accompanied by the surrender of his
stock certificates.

(C)  VALUATION OF SHARES

     The value of the shares of any dissenting shareholder shall be ascertained,
as of the effective date of the merger, by an appraisal made by a committee of
three persons, composed of (1) one selected by the vote of the holders of the
majority of the stock, the owners of which are entitled to payment in cash; (2)
one selected by the directors of the receiving association;  and (3) one
selected by the two so selected.  The valuation agreed upon by any two of the
three appraisers shall govern.  If the value so fixed shall not be satisfactory
to any dissenting shareholder who has requested payment, that shareholder may,
within five days after being notified of the appraised value of his shares,
appeal to the Comptroller, who shall cause a reappraisal to be made which shall
be final and binding as to the value of the shares of the appellant.

(D)  APPLICATION TO SHAREHOLDERS OF MERGING ASSOCIATIONS:  APPRAISAL BY
COMPTROLLER; EXPENSES OF RECEIVING ASSOCIATION;  SALE AND RESALE OF SHARES;
STATE APPRAISAL AND MERGER LAW

     If, within ninety days from the date of consummation of the merger, for any
reason one or more of the appraisers is not selected as herein provided, or the
appraisers fail to determine the value of such shares, the Comptroller shall
upon written request of any interested party cause an appraisal to be made which
shall be final and binding on all parties.  The expenses of the Comptroller in
making the reappraisal or the appraisal, as the case may be, shall be paid by
the receiving association.  The value of the shares ascertained shall be
promptly paid to the dissenting shareholders by the receiving association.  The
shares of stock of the receiving association which would have been delivered to
such dissenting shareholders had they not requested payment shall be sold by the
receiving association at an advertised public auction, and the receiving
association shall have the right to purchase any of such shares at such public
auction, if it is the highest bidder therefor, for the purpose of reselling such
shares within thirty days thereafter to such person or persons and at such price
not less than par as its board of directors by resolution may determine.  If the
shares are sold at public auction at a price greater than the amount paid to the
dissenting shareholders, the excess in such sale price shall be paid to such
dissenting

shareholders.  The appraisal of such shares of stock in any State
bank shall be determined in the manner prescribed by the law of the State in
such cases, rather than as provided in this section, if such provision is made
in the State law;  and no such merger shall be in contravention of the law of
the State under which such bank is incorporated.  The provisions of this
subsection shall apply only to shareholders of (and stock owned by them in) a
bank or association being merged into the receiving association.

(District), Department and Division Heads, and Examining Personnel.

PURPOSE

     This Banking Circular informs all national banks of the valuation methods
used by the Office of the Comptroller of the Currency (OCC) to estimate the
value of a bank's shares when requested to do so by a shareholder dissenting to
the conversion, merger, or consolidation of its bank.  The results of appraisals
performed by the OCC between January 1, 1985, and September 30, 1991 are
summarized.

REFERENCES: 12 U.S.C. 214a, 215 and 215a; 12 CFR 11.590 (item 2)

BACKGROUND

     Under 12 U.S.C. 214a, a shareholder dissenting from a conversion,
consolidation, or merger involving a national bank is entitled to receive the
value of his or her shares from the resulting bank.  A valuation of the shares
shall be made by a committee of three appraisers (a representative of the
dissenting shareholder, a representative of the resulting bank, and a third
appraiser selected by the other two).  If the committee is formed and renders an
appraisal that is acceptable to the dissenting shareholder, the process is
complete and the appraised value of the shares is paid to the dissenting
shareholder by the resulting bank.  If, for any reason, the committee is not
formed or if it renders an appraisal that is not acceptable to the dissenting
shareholder, an interested party may request an appraisal by the OCC. 12 U.S.C.
215 provides these appraisal rights to any shareholder dissenting to a
consolidation.  Any dissenting shareholder of a target bank in a merger is also
entitled to these appraisal rights pursuant to 12 U.S.C. 215a.

     The above provides only a general overview of the appraisal process.  The
specific requirements of the process are set forth in the statutes themselves.

METHODS OF VALUATION USED

     Through its appraisal process, the OCC attempts to arrive at a fair
estimate of the value of a bank's shares.  After reviewing the particular facts
in each case and the available information on a bank's shares, the OCC selects
an appropriate valuation method, or combination of methods, to determine a
reasonable estimate of the shares' value.

Market Value

     The OCC uses various methods to estimate the market value of shares being
appraised.  If sufficient trading in the shares exists and the prices are
available from direct quotes from the Wall Street Journal or a market-maker,
those quotes are considered in determining the market value.  If no market value
is readily available, or if the market value available is not well established,
the OCC may use other methods of estimating market value, such as the investment
value and adjusted book value methods.

Investment Value

     Investment value requires an assessment of the value to investors of a
share in the future earnings of the target bank.  Investment value is estimated
by applying an average price/earnings ratio of banks with similar earnings
potential to the earnings capacity of the target bank.

     The peer group selection is based on location, size, and earnings patterns.
If the state in which the subject bank is located provides a sufficient number
of comparable banks using location, size and earnings patterns as the criteria
for selection, the price/earnings ratios assigned to the banks are applied to
the earnings per share estimated for the subject bank.  In order to select a
reasonable peer group when there are too few comparable independent banks in a
location that is comparable to that of the subject bank, the pool of banks from
which a peer group is selected is broadened by including one-bank holding
company banks in a comparable location, and/or by selecting banks in less
comparable locations, including adjacent states, that have earnings patterns
similar to the subject bank.

Adjusted Book Value

     The OCC also uses an "adjusted book value" method for estimating value.
Historically, the OCC has not placed any weight on the bank's "unadjusted book
value", since that value is based on historical acquisition costs of the bank's
assets, and does not reflect investors' perceptions of the value of the bank as
an ongoing concern.  Adjusted book value is calculated by multiplying the book
value of the target bank's assets per share times the average market price to
book value ratio of comparable banking organizations.  The average market price
to book value ratio measures the premium or discount to book value, which
investors attribute to shares of similarly situated banking organizations.

     Both the investment value method and the adjusted book value method present
appraised values, which are based on the target bank's value as a going concern.
These techniques provide estimates of the market value of the shares of the
subject bank.
   
                                      C-2
<PAGE>
 
OVERALL VALUATION

     The OCC may use more than one of the above-described methods in deriving
the value of shares of stock.  If more than one method is used, varying weights
may be applied in reaching an overall valuation.  The weight given to the value
by a particular valuation method is based on how accurately the given method is
believed to represent market value.  For example, the OCC may give more weight
to a market value representing infrequent trading by shareholders than to the
value derived from the investment value method when the subject bank's earnings
trend is so irregular that it is considered to be a poor predictor of future
earnings.

Purchase Premiums

     For mergers and consolidations, the OCC recognizes that purchase premiums
do exist and may, in some instances, be paid in the purchase of small blocks of
shares.  However, the payment of purchase premiums depends entirely on the
acquisition or control plans of the purchasers, and such payments are not
regular or predictable elements of market value.  Consequently, the OCC's
valuation methods do not include consideration of purchase premiums in arriving
at the value of shares.

STATISTICAL DATA

     The chart below lists the results of appraisals the OCC performed between
January 1, 1985, and September 30, 1991.  The OCC provides statistical data on
book value and price/earnings ratios for comparative purposes, but does not
necessarily rely on such data in determining the value of the banks' shares.
Dissenting shareholders should not view these statistics as determinative for
future appraisals.

April 9, 1996


Board of Directors
The National Bank of Carmi
116 West Main Street
Carmi, Illinois 62821

Members of the Board:

     We understand that The National Bank of Carmi ("Carmi") has entered into an
Agreement of Affiliation and Merger dated March 15, 1996 (the "Agreement") with
Old National Bancorp ("ONB") pursuant to which Carmi will be merged into a
wholly-owned subsidiary of ONB (the "Merger"). Under the terms of the Agreement,
each outstanding share of Carmi Common Stock will be converted into 3.885 shares
of ONB Common Stock. Should the average of the closing prices of ONB Common
Stock, as quoted on the Nasdaq National Market System, be more than 10% above or
below $32.50 per share ($35.75 above or $29.25 below), then the exchange ratio
would be adjusted as provided in the Agreement so as to permit no more than a
10% deviation from the $32.50 value. In addition, Carmi shareholders will
receive as cash dividends the equivalent of the net income of Carmi from January
1, 1996 to closing. You have requested that we render to you our opinion, as
investment bankers, as to the fairness, from a financial point of view, of the
terms of the Merger to the stockholders of Carmi.

     Prairie Capital Services, Inc. ("Prairie Capital") is an investment banking
firm that specializes in providing investment banking and financial advisory
services to banks, thrifts and related holding companies. The principals of
Prairie Capital have performed many independent valuations of bank and thrift
securities and rendered related fairness opinions. The principals of Prairie
Capital have significant experience in management and operations, strategic
planning, investment banking and investment research relating to banks and
thrifts.

     In arriving at our opinion, we have reviewed and analyzed, among other
data: (1) the annual reports to shareholders of Carmi for the years ended
December 31, 1990 through 1994 with financial statements unaudited in 1990
through 1992 and audited in 1993 and 1994 and unaudited interim financial
statements as of and for the eleven months ended November 30, 1995; (2) the
annual reports and 10-K SEC filings for ONB for the years ended December 31,
1990 through 1994, the quarterly reports to stockholders and 10-Q filings for
the first three quarters of 1995, five proxy statements/prospectuses on
transactions completed by ONB in 1995 and a news release dated January 29, 1996
with the unaudited financial statements for the year ended December 31, 1995;
(3) copies of the Agreement of Affiliation and Merger dated March 15, 1996; (3)
draft copies of the S-4 Registration Statement and Proxy Statement/Prospectus;
(4) publicly-available information on the common stock prices and financial
performance of selected Midwestern bank holding companies and ONB; (5) the
announced terms of selected small and medium-sized Midwestern bank merger and
acquisition transactions from September, 1994 through December, 1995; (5) other
information Prairie Capital deemed relevant; and (5) other internal financial
and operating

information which was provided to Prairie Capital by Carmi and ONB. In addition,
we have discussed the foregoing, as well as other matters we deemed relevant to
our inquiry, with members of Carmi and ONB senior managements.

     Prairie Capital reviewed and analyzed ONB Common Stock and financial
performance in relation to the common stocks and financial performances of other
Midwestern bank holding companies. We also gathered information on other small
and medium-sized Midwestern bank merger and acquisition transactions and
compared those relevant transaction with the Merger. Several analyses were made
that compared projected values for Carmi shareholders from Carmi operating
independently and from the ONB Common Stock to be received in the Merger.

     Prairie Capital also took into account its assessment of general economic,
market and financial conditions and its experience in other transactions, as
well as its experience in securities valuation and its knowledge of the banking
industry generally. Prairie Capital's opinion was necessarily based upon
conditions as they existed and could be evaluated on the date hereof and
information made available to Prairie Capital through the date thereof.

     We assumed and relied upon, without independent verification, the accuracy
and completeness of the information reviewed by us for the purposes of our
opinion. Prairie Capital did not make any independent valuation or appraisal of
the assets or liabilities of Carmi and ONB, nor was Prairie Capital furnished
with any such appraisals. Prairie Capital assumed, without independent
verification, that the aggregate allowances and reserves for loan and lease
losses of Carmi and ONB were adequate to cover such losses.

     Based on the foregoing and such other factors as we deem relevant, it is
our opinion as investment bankers that, as of the date hereof, the terms of the
Merger are fair, from a financial point of view, to the stockholders of Carmi.

                                  Very truly yours,



                                  /s/ PRAIRIE CAPITAL SERVICES, INC.
