THE PARTIES TO THE
AFFILIATION:

Old National Bancorp                 As the largest independent bank holding

                                     southern and eastern Illinois and

                                     FUSB and ONB will be accomplished through
                                     three sequential steps: (1) the Asset
                                     Purchase ~ First Citizens Bank & Trust
                                     Company, ONB's affiliate bank in

<PAGE>
  
                                     Greenmark Purchase ~ First Citizens will
                                     purchase the outstanding stock of Greenmark
                                     from FUSB for a purchase price of $310,000;
                                     and (3) the Merger ~ FUSB, as it exists
                                     following these steps, will merge with and

                                     operations will be divided geographically
                                     with First Citizens acquiring the

Reasons for the Affiliation          After careful review and consideration,
                                     FUSB's Board of Directors has determined
                                     that the terms of the Affiliation are fair
                                     to, and in the best interest of, FUSB and
                                     its shareholders. FUSB's Board believes
                                     that the Affiliation will provide
                                     significant value to all FUSB shareholders
                                     and, at the same time, enable holders of
                                     FUSB Common Stock to participate in the
                                     expanded opportunities for growth that the
                                     Affiliation will make possible. FUSB's
                                     Board also determined that the Affiliation
                                     would have a positive, long-term impact on
                                     its customers and employees and the
                                     communities it serves. See "PROPOSED
                                     AFFILIATION -- Background of and Reasons 
                                     for the Affiliation."

                                     its financial advisor in the Affiliation.

                                     of the date of such opinion, the Exchange
                                     Ratio pursuant to the Affiliation was fair,
                                     from a financial point of view, to the
                                     holders of FUSB Common Stock. The opinion
                                     was updated and confirmed on the date of

Board of Directors of                unanimously approved the Agreement and
FUSB                                 recommends that FUSB shareholders approve
                                     the Agreement. See "PROPOSED AFFILIATION --
                                     "Background of and Reasons for the

Affiliation                          to certain conditions which include, among
                                     others, (1) approval of the Agreement by
                                     the affirmative vote of the holders of at
                                     least two-thirds of the outstanding shares
                                     of FUSB Common Stock, (2) receipt of
                                     regulatory approvals for each step of the

                                     unless all of the conditions relating to
                                     each step are met. For tax purposes, the
                                     Asset Purchase and the Greenmark Purchase
                                     must be consummated prior to the Merger.
                                     See "PROPOSED AFFILIATION -- Conditions to
                                     Consummation."

Termination of the Affiliation       The Agreement may be terminated before the
                                     Affiliation becomes effective upon the
                                     occurrence of certain events which include,
                                     among others, (1) a misrepresentation or
                                     breach of any representation or warranty
                                     set forth in the Agreement by ONB or FUSB,
                                     which would result in material adverse
                                     change in either ONB or FUSB on a
                                     consolidated basis, (2) a breach of or
                                     failure to comply with any covenant or
                                     mutual agreement set forth in the Agreement
                                     by ONB or FUSB, (3) the commencement or
                                     threat of certain claims, proceedings or
                                     litigation, (4) a material adverse change
                                     in ONB or FUSB, since June 30, 1994, and
                                     (5) the Affiliation not having been
                                     consummated by January 31, 1996. Further,
                                     ONB may terminate the Affiliation if it
                                     reasonably determines that a condition
                                     imposed by a regulatory agency in
                                     connection with antitrust implications of
                                     the Affiliation would render consummation
                                     of the Affiliation unacceptable or
                                     otherwise imprudent, or if the Affiliation
                                     is not able to be consummated because of
                                     agency disapproval or if a lawsuit is
                                     instituted to enjoin the Affiliation on
                                     antitrust grounds. At present, ONB does not
                                     anticipate that any conditions to
                                     consummation of the Asset Purchase will be
                                     imposed for antitrust purposes. The parties
                                     may also mutually agree to terminate the
                                     Agreement. See "PROPOSED AFFILIATION --
                                     Termination."

Affiliation                          Affiliation will be completed in the last

                                     AFFILIATION -- Effective Date."

                       FIRST UNITED SAVINGS BANK, F.S.B.
                         TO BE HELD ON OCTOBER 31, 1995

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


                              GENERAL INFORMATION

  This Proxy Statement is furnished to the shareholders of FUSB in connection
with the solicitation by the Board of Directors of FUSB of proxies for use at
the Annual Meeting of Shareholders to be held on October 31, 1995, at 2:00 p.m.,
local time, at the main office of the FUSB located at One North Locust Street,
Greencastle, Indiana 46135.  This Proxy Statement is first being mailed to FUSB
shareholders on October ---, 1995.

  The purposes of the Annual Meeting of Shareholders are to (1) consider and
vote upon the Agreement, under the terms of which FUSB will affiliate with ONB
and each outstanding share of FUSB Common Stock will be converted into the right
to receive .8925 of a share of ONB Common Stock, subject to adjustment described
hereinafter; (2) elect two Directors of FUSB for terms expiring in 1998, subject
to earlier termination as a consequence of the Affiliation; and (3) transact
such other business which may properly be presented at the Annual Meeting or any
adjournment thereof.

  Only holders of FUSB Common Stock of record at the close of business on
September 8, 1995 ("Record Date") are entitled to notice of, and to vote at, the
Annual Meeting.  There were 546,550 shares of FUSB Common Stock outstanding on
the Record Date, which were held of record by approximately --- shareholders. A
majority of outstanding shares of Common Stock of FUSB entitled to vote,
represented in person or by proxy, at the Annual Meeting is necessary for a
quorum.  Shareholders who abstain, cast broker non-votes or withhold authority
to vote on one or more Director nominees will be deemed present at the Annual
Meeting for purposes of determining whether a quorum is present.

  The affirmative vote of the holders of at least two-thirds of the outstanding
shares of FUSB Common Stock is required for approval of the Agreement, for which
matter each share of FUSB Common Stock is entitled to one vote.  Directors will
be elected upon receipt of a plurality of affirmative votes cast at the Annual
Meeting.  See "ELECTION OF FUSB DIRECTORS."  In the election of Directors, every
holder of a share of FUSB Common Stock has the right to vote his shares
cumulatively.  Under cumulative voting, the number of shares a shareholder is
entitled to vote multiplied by the number of Directors to be elected represents
the number of votes he may cast at such election, and he may cast all such votes
for one candidate or distribute them among any two or more candidates.

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

  The shares represented by proxies properly signed and returned will be voted
at the Annual Meeting as instructed by the shareholders of FUSB giving the
proxies.  In the absence of specific instructions to the
<PAGE>
 
contrary, proxies will be voted FOR approval of the Agreement described in this
Proxy Statement, FOR election of the slated Directors and in accordance with the
recommendation of the Board of Directors of FUSB with respect to any other
matter which may properly be presented at the Annual Meeting.  Unless otherwise
specified on the accompanying proxy, it is the intention of the persons named in
the proxy to cast one vote per share for each of the Director nominees named
herein.  However, such persons reserve the right to vote each proxy cumulatively
and for the election of fewer than all of the nominees for Directors, but they
do not intend to do so unless candidates other than those Director nominees
named herein are proposed at the Annual Meeting by persons other than the Board
of Directors.

  Any shareholder giving a proxy has the right to revoke it at any time before
it is exercised.  Therefore, execution of a proxy will not affect a
shareholder's right to vote in person if he or she attends the Annual Meeting.
Revocation may be made by a later dated proxy delivered to FUSB, by written
notice delivered to the Secretary of FUSB prior to the Annual Meeting, or by
written notice delivered to the Secretary of FUSB at the Annual Meeting.  To be
effective, any revocation must be received before the proxy is exercised.

 
                                  PROPOSED AFFILIATION

  At the Annual Meeting, shareholders of FUSB 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

  The Affiliation involves three sequential steps, the purpose of which is to
divide the operations of FUSB geographically within the ONB organization:

  (1)  The Asset Purchase.  In the first step of the Affiliation, First Citizens
       will purchase the assets and assume the liabilities of the full service
       branches of FUSB located in Greencastle and of the loan production office
       located in Danville, Indiana. In the transfer, First Citizens will pay
       the fair market value of the acquired assets and liabilities to FUSB. As
       a result, First Citizens will continue to operate as ONB's affiliate
       doing business in Putnam and Hendricks Counties. The specific provisions
       relating to the Asset Purchase are provided for in the Purchase and
       Assumption Agreement attached to this Proxy Statement as Appendix B.

  (2)  The Greenmark Purchase.  First Citizens will then purchase the 
       outstanding stock of Greenmark from FUSB for a purchase price of
       $310,000. As permitted by Indiana law applicable to state banks, First
       Citizens will continue the property, casualty and crop insurance agency
       operations of Greenmark. It must, however, divest the life insurance
       operations to a third party, which will then independently market life
       insurance to First Citizens' customers.

  (3)  The Merger.  FUSB, as it exists following these steps, will immediately
       merge with ONB Interim Federal Savings Bank, a newly formed interim
       savings bank subsidiary of ONB, to create New FUSB. By reason of the
       merger, New FUSB will be a subsidiary of ONB. It will retain its
       corporate title and charter as a federal savings bank, continuing its
       Bloomington operations.

                                      -2-
<PAGE>
 
  All three steps will consummate sequentially on the effective date of the
Affiliation.  Under the terms of the Agreement, none of the steps may consummate
independently; however, for tax purposes, the Asset Purchase and Greenmark
Purchase must consummate prior to the Merger.

  As of June 30, 1995, FUSB had consolidated assets of $142.0 million,
consolidated deposits of $112.3 million, consolidated shareholders' equity of
$9.2 million and consolidated net income for the six calendar months then ended
of $1.6 million.  Based upon the pro forma financial information included
elsewhere in this Proxy Statement and assuming that the Affiliation had been
consummated on June 30, 1995, FUSB represented as of such date 3.21% of the
consolidated assets of ONB, 3.12% of its consolidated deposits, 2.33% of its
consolidated shareholders' equity and, for the six month period ended June 30,
1995, 6.58% of its consolidated net income.  See "PRO FORMA CONDENSED COMBINED
FINANCIAL INFORMATION."

STOCK OPTION AGREEMENT

  At the time of execution of the Agreement, ONB and FUSB entered into a Stock
Option Agreement dated as of September 29, 1994, as amended as of June 29, 1995
("Stock Option Agreement"), pursuant to which FUSB granted an irrevocable option
("Option") to ONB to purchase up to such number of shares of FUSB Common Stock,
which will, immediately following the exercise of the Option in its entirety,
aggregate twenty-four and 80/100 percent (24.80%) of the issued and outstanding
shares of FUSB Common Stock ("Option Shares") at a price per Option Share
("Purchase Price") equal to $26.50 per Option Share.

  The Stock Option Agreement provides that ONB may exercise the Option only if
any of the following events has occurred:  (i) the acquisition by any person or
group of persons, other than ONB or any of its subsidiaries, of beneficial
ownership of fifteen percent (15%) or more of the outstanding shares of FUSB
Common Stock; (ii) the making by any person or group of persons, other than ONB
or any of its subsidiaries, of a tender or exchange offer for fifteen percent
(15%) or more of the shares of FUSB Common Stock if such person or group of
persons has announced its opposition to the Affiliation or an intention not to
vote in favor of the Affiliation or if such person or group of persons has
announced its intention to enter into or entered into, an agreement to effect a
merger consolidation, share exchange or other combination with FUSB; or (iii)
the acceptance by FUSB of any firm proposal, however conditional or future, by
any person or group of persons, other than ONB or any of its subsidiaries, to:
(a) acquire FUSB by merger, consolidation, purchase of all or substantially all
of FUSB's assets or capital stock or any other similar transaction, or (b) make
a tender or exchange offer described in (ii) above.

  If the conditions to exercise of the Option have been met, the Option may be
exercised by ONB in whole or in part at any time prior to January 31, 1996,
provided, however, that the Option will automatically expire if the Affiliation
is consummated as contemplated by the Agreement.  In the event that ONB
exercises the Option, the option fee of $1,000 previously paid by ONB to FUSB
will be applied against the Purchase Price of the Option Shares.

  The Stock Option Agreement provides that in the event that ONB has purchased
all of the Option Shares pursuant to the Stock Option Agreement, ONB may require
FUSB to pay ONB an amount in cash equal to the highest price paid or to be paid
by any person or group of persons for any share of FUSB Common Stock (or the
aggregate consideration paid for the assets of FUSB divided by the number of
shares of FUSB Common Stock then outstanding), as the case may be, multiplied by
the total number of Option Shares, plus interest at the rate of eight percent
(8%) per annum from the date of the purchase of the Option Shares through the
date of such repurchase.  Additionally, the value of any such price or

case of consideration with a readily-ascertainable market value, on the basis of
such market value and, in the case of any other consideration, by agreement
between ONB and FUSB.

  The Stock Option Agreement provides that in the event the Option is exercised
by ONB and the Agreement is terminated in accordance with the terms thereof,
FUSB will have the right to purchase, and ONB will have the right to require
FUSB to purchase, for cash, all of the Option Shares purchased by ONB pursuant
to the Stock Option Agreement.  The purchase price for such Option Shares will
be calculated in the manner described in the previous paragraph.

BACKGROUND OF AND REASONS FOR THE AFFILIATION

  Until 1985 Indiana banking laws prohibited banks located in Indiana from
expanding outside of their home counties.  Moreover, until 1989 federal law
prohibited affiliations between healthy savings and loan associations and banks
or bank holding companies.  The changes since that time have been swift, first
permitting in-state acquisitions of banks by bank holding companies, then
permitting regional interstate acquisitions and finally permitting virtual
nationwide expansion opportunities, including cross-industry acquisitions.
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
industry generally have led to further increases in competition for financial
institution services.  Compounded by the significant increase in regulatory
burdens over the past several years, these competitive factors have created an
environment in which it is increasingly difficult for community organizations
such as FUSB to achieve the economies of scale necessary to compete effectively.

  In April of 1994, FUSB received an unsolicited indication of interest from a
bank holding company regarding an affiliation with FUSB.  Partly in response to
this unsolicited proposal and after an evaluation of the competitive and
regulatory factors described above and other financial, legal, economic and
market considerations, FUSB engaged McDonald & Company in June of 1994, to
contact a number of institutions on behalf of FUSB which might be interested in
a business combination with FUSB.  On June 27, 1994, FUSB publicly announced its
engagement of McDonald & Company.  During June and July of 1994, 24 bank and
thrift holding companies were contacted by McDonald & Company.  The institutions
contacted included companies which FUSB and McDonald & Company believed would
have a strategic interest in FUSB and the financial ability to acquire FUSB and
companies that expressed an interest in a business combination following FUSB's
public announcement of its evaluation of strategic alternatives deemed to have
the financial ability to pursue such a transaction.  Twenty-two of those
institutions executed confidentiality agreements, after which they were provided
selected confidential information regarding FUSB.  On July 27, 1994, FUSB
announced that it had hired McDonald & Company to assist it in locating a
financial institution with whom it might affiliate, and, as a result of that
announcement, received contacts from a number of other financial institutions.
As a result of these contacts, seven institutions submitted written proposals
during July of 1994, and four were offered the opportunity to conduct a due
diligence investigation of FUSB.

  Final proposals were submitted by three of these institutions, including ONB,
in September of 1994.  At a Board of Directors meeting held on September 16,
1994, FUSB, with the assistance of McDonald & Company and legal counsel,
analyzed each proposal and determined that the proposal submitted by ONB
provided the best opportunity for FUSB and its shareholders.  As a result, the
directors authorized McDonald & Company and its legal counsel to proceed with
negotiations on behalf of FUSB for a definitive agreement with ONB.

                                      -4-

<PAGE>
 
  On the evening of September 29, 1994, the agreement was approved by both
parties and a press release regarding the execution of that agreement was issued
the next day. At the September 29, 1994 meeting of the FUSB Board, McDonald &
Company rendered its oral opinion, which was subsequently  delivered in writing,
to the effect that, as of that date, the Exchange Ratio pursuant to the
Affiliation was fair, from a financial point of view, to the holders of FUSB
Common Stock.  On the same date, FUSB granted ONB an option to acquire 24.8% of
its Common Stock, in order to protect ONB's proposed affiliation with FUSB from
other interested parties.

  After review of regulatory considerations regarding the proposed transaction,
ONB and FUSB determined that it was in the best interests of the parties to
structure the transaction in the steps comprised of the Asset Purchase,
Greenmark Purchase and the Merger.  To reflect this structure, the parties
amended and restated the original agreement on June 29, 1995, and entered into
the Purchase and Assumption Agreement relating to the Asset Purchase and
Greenmark Purchase, annexed hereto as Appendix B.

  In determining to pursue the Affiliation, the Board of Directors of FUSB
specifically considered financial, managerial and other information regarding
ONB and its affiliate banks.  In particular, the Board of Directors of FUSB
evaluated the respective businesses, financial condition and future prospects of
FUSB and ONB.  The earnings history and stock performance of ONB were carefully
reviewed and discussed with McDonald & Company with a view towards the
investment potential for shareholders of FUSB.

  Among other items considered in this evaluation were the prospects of FUSB and
ONB, as separate institutions and as combined; the compatibility of ONB's
affiliate bank markets to those of FUSB; the anticipated tax-free nature of the
Affiliation to FUSB shareholders receiving solely ONB Common Stock in exchange
for their shares of FUSB Common Stock; 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; an
analysis of alternatives to affiliating with ONB, including other potential
acquirors; the fact that the consideration to be received in the Affiliation by
FUSB shareholders reflects a significant premium for FUSB Common Stock over the
market prices at which such stock had traded in the weeks prior to the public
announcement relating to the retention of McDonald & Company and the Affiliation
on July 27, 1994 and September 30, 1994, respectively; the competitive process
undertaken by FUSB with the assistance of McDonald & Company and the expressions
of interest made by other financial institutions; the value implicit in the
Exchange Ratio in relation to book value and earnings of FUSB and the dividend
rate that FUSB shareholders who become ONB shareholders would be expected to
enjoy as a result of the Affiliation; the terms of the Agreement; and McDonald &
Company's fairness opinion.

  The Board of Directors of FUSB also considered the impact of the Affiliation
on its customers and employees and the communities it serves.  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 FUSB's employees within ONB or one of its
affiliates.  The Board of Directors of FUSB examined ONB's continuing commitment
to the communities served by institutions previously acquired by ONB.  Further,
from the standpoint of 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 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 FUSB

  FUSB retained McDonald & Company to act as its financial advisor in connection
with the Affiliation. McDonald & Company participated with management of FUSB in
negotiating the terms of the Affiliation. Representatives of McDonald & Company
attended meetings of FUSB's Board of Directors in connection with the evaluation
of a possible business combination with another financial institution and in
connection with the evaluation of the Affiliation, including the meeting held on
September 29, 1994 at which time the Affiliation was approved.  At such meeting,
representatives of McDonald & Company made an oral presentation to FUSB's Board
and reviewed with the Directors the various aspects of the Affiliation,
including the financial terms and conditions thereof.

  At the September 29, 1994 meeting of FUSB's Board, McDonald & Company rendered
its oral opinion to the effect that, as of that date, the Exchange Ratio
pursuant to the Affiliation was fair, from a financial point of view, to the
holders of FUSB Common Stock.  In addition, McDonald & Company has delivered its
written opinion to FUSB's Board dated as of September 29, 1994 and as of the
date of this Proxy Statement stating that, as of September 29, 1994 and as of
the date of this Proxy Statement, the Exchange Ratio pursuant to the Affiliation
is fair, from a financial point of view, to the holders of FUSB Common Stock.
McDonald & Company has consented to the inclusion herein of the summary of its
opinion to FUSB's Board dated September 29, 1994 and to the reference to the
entire opinion dated as of the date of this Proxy Statement attached hereto as
Appendix C.
 
  THE FULL TEXT OF MCDONALD & COMPANY'S FAIRNESS OPINION ("OPINION"), DATED AS
OF THE DATE OF THIS PROXY STATEMENT, WHICH SETS FORTH THE ASSUMPTIONS MADE,
MATTERS CONSIDERED AND LIMITS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS APPENDIX
C TO THIS PROXY STATEMENT.  FUSB SHAREHOLDERS ARE URGED TO READ THE OPINION IN
ITS ENTIRETY.  MCDONALD & COMPANY HAS NOT MADE OR SOUGHT TO OBTAIN APPRAISALS OF
FUSB' ASSETS IN RENDERING THE OPINION.  NEITHER FUSB NOR ONB PLACED ANY
LIMITATION UPON MCDONALD & COMPANY WITH RESPECT TO THE INVESTIGATIONS MADE OR
PROCEDURES FOLLOWED BY MCDONALD & COMPANY IN RENDERING THE OPINION.  THE OPINION
IS DIRECTED SOLELY TO THE BOARD OF DIRECTORS OF FUSB AND CONCERNS ONLY THE
CONSIDERATION PROVIDED FOR IN THE AGREEMENT AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY OF FUSB' SHAREHOLDERS AS TO HOW SUCH SHAREHOLDER SHOULD
VOTE AT THE ANNUAL MEETING.  THE SUMMARY OF THE OPINION SET FORTH IN THIS PROXY
STATEMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE
OPINION INCLUDED IN APPENDIX C HERETO.

  In arriving at its opinion, McDonald & Company reviewed, among other things,
the Agreement together with exhibits and schedules thereto, certain publicly
available information relating to the business, financial condition and
operations of FUSB and ONB as well as certain other non-public information
primarily financial in nature, furnished to it by FUSB and ONB relating to the
respective businesses, earnings, assets, financial forecasts and prospects.
McDonald & Company also held discussions with members of senior management of
FUSB and ONB concerning their respective businesses, assets, financial forecasts
and prospects.  McDonald & Company also reviewed certain publicly available
information concerning the trading of, and the trading market for, FUSB Common
Stock and ONB Common Stock and certain publicly available information concerning
comparable companies and transactions, all as more fully set forth in its
opinion.

  McDonald & Company was not engaged to and did not conduct a physical
inspection of any of the assets, properties or facilities of either FUSB or ONB,
and was not engaged to do and has not made, obtained or been furnished with any
independent evaluation or appraisal of any such assets, properties or facilities
or any of the liabilities of FUSB or ONB.  McDonald & Company has assumed and
relied, without independent investigation, upon the accuracy and completeness of
the financial and other information provided to it or publicly available,

                                      -6-

<PAGE>
 
has relied upon the representations and warranties of FUSB and ONB contained in
the Agreement, and has not independently attempted to verify any such
information.  McDonald & Company has also assumed that all of the conditions to
the Affiliation as set forth in the Agreement, includng the tax-free treatment
of the Affiliation to the shareholders of FUSB Common Stock, would be
consummated on a timely basis in the manner contemplated by the Agreement.  No
limitations were imposed by FUSB upon McDonald & Company with respect to the
scope of its investigation nor were any specific instructions given to McDonald
& Company in connection with its opinion.

  In connection with rendering its opinion dated September 29, 1994, McDonald &
Company considered a variety of financial analyses which are summarized below.
McDonald & Company believes that its analyses must be considered as a whole and
that selecting portions of such analyses and factors may create an incomplete
view of the analytical process underlying McDonald & Company's opinion.  In its
analyses, McDonald & Company made numerous assumptions with respect to industry
performance, business and economic conditions, and other matters.  Any estimates
contained in McDonald & Company's analyses are not necessarily indicative of
future results or values, which may be significantly more or less favorable than
such estimates.

  The following is a summary of selected analyses considered by McDonald &
Company in connection with McDonald & Company's opinion dated September 29,
1994:

  COMPARISON WITH SELECTED COMPANIES.  McDonald & Company compared the financial
performance and stock market valuation of FUSB with corresponding data for the
following selected thrifts: First Financial Bancorp, Inc., Glenway Financial
Corp., Haverfield Corporation, LGF Bancorp, Inc., SuburbFed Financial Corp.,
Security Savings Bank, FSB, and United Financial Bancorp.  In addition, McDonald
& Company compared such data of ONB with the following selected banking
companies: Citizens Banking Corporation, Commerce Bancshares, Inc., Chemical
Financial Corporation, FirstMerit Corp., First Commerce Bancshares, First
Financial Bancorp, FirsTier Financial, Inc., Fort Wayne National Corp., Hawkeye
Bancorporation, Mid-America Bancorp, Mid Am, Inc., Peoples First Corporation,
Park National Corp., and Star Banc Corp.  At the time, none of the companies
listed above had announced a merger transaction or disclosed a possible interest
in pursuing a possible merger transaction which would have significantly
affected its stock market valuation.

  PRO FORMA MERGER ANALYSES.  McDonald & Company analyzed the changes in per
share amount of earnings, book value and indicated dividend represented by one
share of FUSB Common Stock after the Affiliation.  The analysis was performed on
the basis of financial information for both companies as of and for the twelve
months ended June 30, 1994, December 31, 1993, and December 31, 1992.  The
analysis indicated, among other things, that exchanging one share of FUSB Common
Stock at the Exchange Ratio for shares of ONB Common Stock on a pro forma basis
would have resulted in a 59.5% increase in earnings per share for each share of
FUSB Common Stock for the twelve months ended December 31, 1993, a 18.6%
decrease in book value per share for each share of FUSB Common Stock as of June
30, 1994, and a 225.0% increase in dividends per share of FUSB Common Stock
based on FUSB's and ONB's indicated annual dividend rate as of September 29,
1994.

  ANALYSIS OF SELECTED MERGER TRANSACTIONS.  McDonald & Company reviewed four
groups of selected pending thrift transactions involving (i) selling thrifts
with total assets less than $400 million, (ii) selling thrifts having a tangible
equity to assets ratio of more than 6.00%, (iii) selling thrifts having a return
on assets of less than 0.70%, and (iv) selling thrifts having non-performing
assets as a percent of total assests less than 2.00%. McDonald & Company
reviewed the ratios of the offer value to stated book value and tangible book
value, the multiple of the last twelve months earnings of the acquired company,
and the ratio of the offer value to assets in each such transaction and computed
mean and median ratios and multiples for each group.  The calculations

                                      -7-

<PAGE>
 
yielded ranges of median ratios of price to stated book value and tangible book
value of 131% to 168% and 133% to 169%, respectively.  Median multiples of
earnings among the four groups ranged from 13.7x to 17.7x, and median ratios of
offer value to assets ranged from 10.0% to 14.6%.  Based on the Exchange Ratio
and the ONB equivalent price per share as of September 29, 1994 of $36.50, the
ratio of price to stated book value and tangible book value were 171% and 177%,
respectively.  The multiple of price to last twelve months earnings before
extraordinary charges of FUSB through June 30, 1994 was 32.0x and the ratio of
price to assets at June 30, 1994 was 13.5%.

  NO COMPANY OR TRANSACTION USED IN THE ABOVE ANALYSES AS A COMPARISON IS
IDENTICAL TO FUSB, ONB, OR THE AFFILIATION.  ACCORDINGLY, AN ANALYSIS OF THE
RESULTS OF THE FOREGOING NECESSARILY INVOLVES COMPLEX CONSIDERATIONS AND
JUDGEMENTS CONCERNING THE DIFFERENCES IN FINANCIAL AND OPERATING CHARACTERISTICS
OF THE COMPANIES AND OTHER FACTORS THAT COULD AFFECT THE PUBLIC TRADING VALUES
OR ACQUISITION VALUES OF THE COMPANIES TO WHICH THEY ARE BEING COMPARED.
MATHEMATICAL ANALYSIS (SUCH AS DETERMINING THE MEAN OR MEDIAN) IS NOT, IN
ITSELF, A MEANINGFUL METHOD OF USING COMPARABLE COMPANY OR COMPARABLE
TRANSACTION DATA.

  DISCOUNTED CASH FLOW ANALYSIS.  Using a discounted cash flow analysis,
McDonald & Company estimated the present value of the future streams of after-
tax cash flows that FUSB could produce over a five year period from 1995 through
1999, under various assumptions, based upon FUSB management's forecasts.
McDonald & Company estimated the terminal value of FUSB after the five year
period by applying an estimated perpetual growth rate to the terminal year's
projected after-tax cash flow and then applied to this, multiples ranging from
9x to 11x.  The cash flow streams and terminal values were then discounted to
present values using different discount rates chosen to reflect different
assumptions regarding the required rates of return of prospective buyers of
FUSB.  On the basis of such varying assumptions, this discounted cash flow
analysis indicated a reference range of $20.67 to $27.92 per share of FUSB
Common Stock.  This analysis was based upon management projections including
variations and assumptions made by McDonald & Company which included adjustments
to reflect the anticipated effects of potential merger-related cost savings
estimated by FUSB, as well as the effects of the potential tax liability for
conversion of FUSB Savings Bank to a commercial bank charter.  Management's
projections are based upon many factors and assumptions, many of which are
beyond the control of FUSB or ONB.  As indicated above, this analysis is not
necessarily indicative of actual values or actual future results and does not
purport to reflect the process at which any securities may trade at the present
time or at any time in the future.

  In performing its analyses, McDonald & Company made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters.  The analyses performed by McDonald & Company are not necessarily
indicative of actual values, which may be significantly more or less favorable
than the values suggested by such analyses.  Such analyses were prepared solely
as part of McDonald & Company's opinion.  The term "fair from a financial point
of view" is a standard phrase contained in investment banker fairness opinions
and refers to the fact that McDonald & Company's opinion as to the fairness of
the Exchange Ratio is addressed solely to the financial attributes of the
Exchange Ratio.  The analyses do not purport to be appraisals or to reflect the
prices at which a company might actually be sold.  In addition, as described
above, McDonald & Company's fairness opinion and presentation to the FUSB Board
of Directors were one of many factors taken into consideration by the FUSB Board
of Directors in making its determination to approve the Agreement.
Consequently, the McDonald & Company analyses described above should not be
viewed as determinative of the FUSB Board of Directors' conclusions with respect
to the value of FUSB or of the decision of the FUSB Board of Directors to agree
to the Exchange Ratio.

                                      -8-

  McDonald & Company's opinions are based on economic and market conditions and
other circumstances existing on, and information made available as of, the date
of such opinion.  In addition, the opinions do not address FUSB' underlying
business decision to effect the Affiliation or any other terms of the
Affiliation. McDonald & Company is not rendering any opinion as to the value of
FUSB Common Stock or ONB Common Stock at the Effective Time.

  In connection with its opinion dated as of the date of this Proxy Statement,
McDonald & Company performed procedures to update certain of its analyses and
reviewed the assumptions on which such analyses were based and the factors
considered therewith.

  McDonald & Company, as part of its investment banking business, is customarily
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements and valuations for estate,
corporate and other purposes.  McDonald & Company has extensive experience with
the valuation of financial institutions. FUSB's Board of Directors selected
McDonald & Company as its financial advisor because of McDonald & Company's
industry expertise with respect to financial institutions and because of
McDonald & Company's industry experience in transactions similar to the
Affiliation.  McDonald & Company is not affiliated with either FUSB or ONB.

  In the ordinary course of business, McDonald & Company makes a market in FUSB
Common Stock and ONB Common Stock and may actively trade the securities of FUSB
and ONB for its own account and for the accounts of its customers.  Accordingly,
at any time McDonald & Company may hold a long or short position in such
securities.  In addition, McDonald & Company from time to time has provided
investment banking services to FUSB and may provide such services to ONB in the
future.

  For its services as financial advisor, FUSB has paid McDonald & Company a
retainer of $15,000 and a fee of $35,000 upon the rendering of McDonald &
Company's September 29, 1994 fairness opinion.  Additional fees equal to
approximately $189,000 will be payable to McDonald & Company upon consummation
of the Affiliation.  FUSB has also agreed to reimburse McDonald & Company for
its reasonable out-of-pocket expenses and to indemnify McDonald & Company
against certain liabilities, including certain liabilities under federal
securities laws.

RECOMMENDATION OF THE BOARD OF DIRECTORS

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

  Certain members of the management and Board of Directors of FUSB have
interests in the Affiliation that are in addition to those of FUSB shareholders
generally.  See "Interests of Certain Persons in the Affiliation" and
"Management, Personnel and Operations After the Transaction."

EXCHANGE OF FUSB COMMON STOCK

  Under the terms of the Agreement, shareholders of FUSB of record upon
consummation of the Affiliation (excluding Greenmark, which will have its 1,000
shares canceled on the effective date) will be entitled to receive .8925 of a
share of ONB Common Stock in exchange for each share of FUSB Common Stock held,
subject to

                                      -9-

<PAGE>
 
adjustment if the Average Price Per Share (as defined below) is more than ten
percent above or below $34.7619 or in the event of a recapitalization of ONB.
As a result of the ten percent limitation:

  (1)  Increase in Average Price Per Share. If the Average Price Per Share of
       ONB Common Stock exceeds $38.2381, then the exchange ratio will be
       adjusted such that each issued and outstanding share of FUSB Common Stock
       will be converted into the right to receive a fraction of a share of ONB
       Common Stock determined by dividing $34.1275 by the Average Price Per
       Share of ONB Common Stock. 

  (2)  Decrease in Average Price Per Share. Similarly, if the Average Price Per
       Share of ONB Common Stock is less than $31.2857, then the exchange ratio
       will be adjusted such that each issued and outstanding share of FUSB
       Common Stock will be converted into the right to receive a fraction of a
       share of ONB Common Stock determined by dividing $27.9225 by the Average
       Price Per Share of ONB Common Stock.

  (3)  Less Than Ten Percent Change. If the Average Price Per Share of ONB
       Common Stock is not less than $31.2857 nor more than $38.2381, then there
       will be no adjustment to the exchange ratio.

The "Average Price Per Share" of ONB Common Stock is defined in the Agreement as
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 date of the Affiliation.

  As of September ---, 1995, the closing price of ONB Common Stock was $--- 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 merger would have been ---------, with an aggregate market
value of approximately $--- million.

  No fractional shares of ONB Common Stock will be issued to shareholders of
FUSB in connection with the Affiliation.  Each shareholder of FUSB who otherwise
would be entitled to a fractional interest in a share of ONB Common Stock as a
result of the Exchange Ratio will be paid a cash amount equal to such fractional
interest multiplied by the Average Price Per Share of ONB Common Stock.

  In connection with the Affiliation, Directors and executive officers of FUSB
who held outstanding options to purchase FUSB Common Stock were required to
exercise such options prior to consummation.  Accordingly, those shares will be
exchanged for ONB Common Stock on the same terms disclosed above.

  After the effective time of the Affiliation, stock certificates previously
representing FUSB Common Stock will represent only the right to receive shares
of ONB Common Stock and cash for any fractional shares. Following the effective
date of the Affiliation and prior to the surrender by holders of FUSB of their
stock certificates to ONB for exchange, 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
date of the Affiliation, the stock transfer books of FUSB will be closed and no
transfers of shares of FUSB Common Stock will thereafter be made.  If, after the
effective date, certificates representing shares of FUSB Common Stock are
presented for registration or transfer, they will be canceled and exchanged for
shares of ONB Common Stock.

                                     -10-
<PAGE>
 
  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 date of the Affiliation, to each former shareholder of FUSB within
ten (10) business days following the shareholder's delivery to ONB of his or her
certificate(s) representing shares of FUSB Common Stock.  Instructions as to
delivery of FUSB stock certificates to ONB will be sent to each FUSB shareholder
shortly after the effective date of the Affiliation.

NO DISSENTERS' OR APPRAISAL RIGHTS

  In connection with the Affiliation, shareholders of FUSB do not have the
statutory right to dissent and require appraisal of their shares of FUSB Common
Stock.  Federal law applicable to FUSB excepts transactions from dissenters'
rights provisions when the stock held by shareholders is listed on the NASDAQ as
of the date of the shareholder meeting and when the stock being offered is
listed as of the effective date.  FUSB Common Stock and ONB Common Stock,
respectively, meet these tests.  Shareholders of FUSB who would otherwise
dissent to the Affiliation may sell their shares of ONB Common Stock in the open
market at the market price following the effective date.

RESALE OF ONB COMMON STOCK BY FUSB AFFILIATES

  No restrictions on the sale or transfer of the shares of ONB Common Stock
issued in the Affiliation will be imposed solely as a result of the Affiliation,
other than restrictions on the transfer of such shares issued to any FUSB
shareholder who may be deemed to be an "affiliate" of FUSB 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 FUSB will provide ONB with a list identifying each
affiliate of FUSB.  The Agreement also requires that each FUSB affiliate deliver
to ONB, prior to the effective date of the Affiliation, a written agreement to
the effect that such affiliate (1) has not sold, pledged, transferred, disposed
of or otherwise reduced the affiliate's market risk with respect to the shares
of FUSB Common Stock directly or indirectly owned or held by such person during
the thirty (30) day period prior to the effective date, and (2) 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 (i) until such time as financial results covering at
least thirty (30) days of combined operations of FUSB and ONB have been
published within the meaning of Section 201.01 of the Commission's Codification
of Financial Reporting Policies and (ii) 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 FUSB affiliates 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 FUSB who may be deemed to be affiliates of FUSB
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 FUSB Common Stock, (2)  receipt by ONB
and FUSB of all applicable regulatory approvals required for each step of the
Affiliation, (3) receipt of an Internal Revenue Service letter ruling or opinion
of counsel with respect to certain federal
 
                                     -11-
<PAGE>
 
income tax matters, (4) the issuance by McDonald & Company of a written fairness
opinion stating that the terms of the Affiliation are fair to the shareholders
of FUSB from a financial point of view dated as of the date hereof and confirmed
as of the effective date, (5) receipt by ONB of certain undertakings from
affiliates of FUSB, (6) receipt by ONB and FUSB of certain officers'
certificates and legal opinions, (7) the accuracy at the effective date of the
Affiliation of representations and warranties contained in the Agreement, (8)
the fulfillment of certain covenants and mutual agreements set forth in the
Agreement and (9) the exercise of all stock options held by officers and
directors of FUSB prior to the effective date.  While the three steps of the
Affiliation will consummate on the effective date, it is a condition of the
Affiliation imposed for tax purposes that the Asset Purchase and the Greenmark
Purchase consummate prior to the Merger.  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.

TERMINATION

  The Agreement may be terminated before consummation of the Affiliation by
either ONB or FUSB (as set forth in the Agreement) if, among other reasons, (1)
there has been a misrepresentation or a breach of any representation or warranty
set forth in the Agreement by FUSB or ONB which has had or could be expected to
have a material adverse effect on the financial condition, results of
operations, business, prospects, assets or capitalization of FUSB or ONB, or in
the number of issued and outstanding shares of FUSB, (2) ONB or FUSB has
breached or failed to comply with any covenant or mutual agreement 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, FUSB, First Citizens or any subsidiary of ONB or of
FUSB, or any officer or director of either relating to the Agreement or which is
likely to have a material adverse effect on the financial condition, results of
operations, business, prospects, assets or capitalization of ONB or FUSB, each
on a consolidated basis, (4) there has been a material adverse change in the
financial condition, results of operations, business,  prospects, assets or
capitalization of ONB or FUSB, each on a consolidated basis, as of the effective
date of the Affiliation as compared to that in existence as of June 30, 1994,
(5) ONB's accountants conclude that ONB cannot utilize the pooling-of-interests
method of accounting for the Affiliation, or (6) consummation of the Affiliation
has not occurred by January 31, 1996. Further, ONB may terminate the Affiliation
if it reasonably determines that a term or condition imposed by a regulatory
agency in connection with antitrust implications of the Asset Purchase would so
materially and adversely impact the anticipated financial condition or results
of operations of New FUSB or First Citizens on a consolidated basis with ONB as
to render consummation unacceptable or otherwise imprudent, or the Affiliation
is not able to be consummated because of governmental disapproval or a lawsuit
is filed to enjoin the Affiliation on antitrust grounds.  At present, ONB does
not anticipate that the Asset Purchase will be subject to conditions to
consummation as a result of the antitrust implications.  The parties may also
mutually agree to terminate the Affiliation.  Upon termination for any of these
reasons, the Agreement will be of no further force or effect.

RESTRICTIONS AFFECTING FUSB

  The Agreement contains a number of restrictions regarding the conduct of
business of FUSB pending consummation of the Affiliation.  Among other items,
FUSB may not, without the prior written consent of ONB, (1) change its capital
stock accounts, (2) distribute or pay any dividends, except that FUSB may pay to
its shareholders its normal and customary quarterly cash dividend in amounts not
to exceed $0.12 per share; provided, however, that no dividend may be paid to
shareholders of FUSB during the quarter in which the Affiliation is consummated,
if, during such quarter, FUSB shareholders will become entitled to receive
dividends on their shares of ONB Common Stock received pursuant to the
Agreement, (3) amend its Charter or By-Laws, (4) carry on its business other
than substantially in the manner as conducted as of the date of
 
                                     -12-
<PAGE>
 
the Agreement and in the ordinary course of business, or (5) negotiate or
discuss with third parties relative to a merger, combination or sale of FUSB,
except under certain limited circumstances.

REGULATORY APPROVALS

  Each step of the Affiliation requires regulatory approvals in order to be
effective: the Asset Purchase and Greenmark Purchase require the approvals of
the OTS, Indiana Department of Financial Institutions and FDIC; while the Merger
requires the approvals of the Board of Governors of the Federal Reserve System
under the Bank Holding Company Act of 1956, as amended and of the OTS.  The
Asset Purchase involves antitrust considerations because First Citizens and FUSB
compete directly in Greencastle and Putnam County. ONB, however, does not
anticipate that the Asset Purchase will raise significant antitrust issues.

  Approval of the Affiliation is not to be interpreted as the opinion of these
regulatory authorities that the Affiliation is favorable to the shareholders of
FUSB from a financial point of view or that those regulatory authorities have
considered the adequacy of the terms of the Affiliation.  Regulatory approval 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 and it is a condition precedent to ONB's obligation to
consummate the Affiliate that it be so treated.  Under this method of
accounting, shareholders of ONB and shareholders of FUSB 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."

EFFECTIVE DATE

  The Affiliation will become effective at the close of business on the day
specified in certificates filed with the OTS, Indiana Department of Financial
Institutions and FDIC.  The effective date will occur on the last business day
of the month during which occurs (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 regulatory applications filed for
approval of the Affiliation.

  ONB and FUSB currently anticipate that the Affiliation will consummate during
the last calendar quarter of 1995.

MANAGEMENT, PERSONNEL AND OPERATIONS AFTER THE AFFILIATION

  The Directors of FUSB elected at the Annual Meeting and serving at the
effective date of the Affiliation will continue as Directors of either New FUSB
or First Citizens.  Following the effective date of the Affiliation, ONB, as the
sole shareholder of New FUSB and First Citizens, will have the ability to elect
the respective Boards of Directors; however, ONB has agreed that the former
Directors of FUSB will continue as Directors for at least three years following
the effective date of the Affiliation.  The directors based in and around
Greencastle will serve as directors of First Citizens; those based in and around
Bloomington will serve as directors of New FUSB.  William M. Marley, President
of FUSB, will serve as Vice Chairman of First Citizens.  The remaining officers
of FUSB will continue in their respective positions after the effective date,
with geographic distribution between New FUSB's Bloomington operations and First
Citizens' Greencastle
 

                                      -13-
<PAGE>
 
operations.  The officers working in Greencastle and Danville at the effective
date will serve as officers of First Citizens; those working in Bloomington on
the effective date will serve as officers of New FUSB.

  In general, employees of FUSB will receive benefits in accordance with
policies of ONB following the Affiliation.  In particular, those persons who are
full-time officers or employees of FUSB as of the effective date of the
Affiliation, who continue as full-time officers or employees of First Citizens,
New FUSB or any other subsidiary of ONB after the effective date, will receive
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, including participation in the ONB
Employees' Retirement Plan ("ONB Pension Plan") and the ONB Employees' Savings
and Profit Sharing Plan ("ONB Profit Sharing Plan").  In addition, years of
service of an employee of FUSB prior to the effective date 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 benefit accrual or contributions under the ONB Pension Plan and the ONB
Profit Sharing Plan.

  Those officers and employees of FUSB who otherwise meet the eligibility
requirements of the ONB Profit Sharing Plan, based upon their age and years of
service for FUSB, will become participants thereunder as of the January 1st
which coincides with or next follows the effective date of the termination of
the employee stock ownership plan sponsored by FUSB.  Those employees of FUSB
who otherwise meet the eligibility requirements of the ONB Pension Plan, based
upon their age and years of service, will become participants thereunder on the
January 1st which coincides with or next follows the effective date of the
termination of the defined benefit pension plan sponsored by FUSB.  Those
officers and employees who do not meet the eligibility requirements of the ONB
Pension Plan or ONB Profit Sharing Plan on such dates will become participants
thereunder on the first "plan entry date" (as defined in 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.

  Further, FUSB has agreed that prior to the effective date, it will amend each
Director Supplemental Benefit Plan Agreement for each director of FUSB who is
not in pay status as of such effective date to (1) increase the monthly
allocation due under of the agreement from $350 to $700 to be effective as of
the effective date of the Affiliation; (2) provide for the cessation of benefit
accruals under each agreement effective as of the end of the month which
coincides with or next follows the end of the three year period beginning at the
effective date of the Affiliation in addition to provisions for benefit accrual
cessation currently in the agreements; (3) eliminate the minimum monthly benefit
provisions; and (4) provide for a lump sum cash payment of the director's
account balance under the agreement payable within ten business days following
the earliest of the benefit cessation date or the date the director ceases to be
a director of an affiliate of ONB or the date the director attains age sixty-
five.

  In addition, prior to the effective date of the Affiliation, FUSB will enter
into a Director Supplemental Benefit Plan Agreement with Alan G. Stanley to (1)
provide for a monthly allocation in the amount of $350 to be effective as of the
effective date of the Affiliation, such monthly allocations to be made for a
period ending as of the end of the month which coincides with or next follows
the end of the three year period beginning at the effective date of the
Affiliation; (2) provide for the cessation of benefit accruals under such
agreement effective as of the end of the month which coincides with or next
follows the end of the three year period beginning at such effective date of the
Affiliation; and (3) provide for a lump sum cash payment of the account balance
under the agreement payable within ten business days following the earliest of
the benefit cessation date or the date Mr. Stanley ceases to be a director of an
affiliate of ONB.
  
                                      -14-
<PAGE>
 
  ONB has also agreed not to reduce the monthly allocation under the Director
Supplemental Benefit Plan Agreements for the three year period beginning as of
the effective date of the Affiliation.   During such three year period, ONB will
not make any other modifications to any of the foregoing agreements (whether or
not in pay status) without first receiving the written consent of the affected
individual, unless otherwise required by law.

  The changes to the Director Supplemental Benefit Plans of FUSB discussed above
will enable the Directors of FUSB to receive approximately the same level of
director benefits (including director's fees) as they are presently receiving
from FUSB for three years following the Affiliation and do not represent an
increase in those benefits.

  Upon consummation of the Affiliation, ONB will cause the Employee Supplemental
Benefit Plan Agreements entered into between FUSB and each of Rosa Ada Wood,
Donna L. Bouslog and William M. Marley, as amended, to be terminated; provided,
however, that within ten business days of the termination of such agreements,
ONB must make a lump sum cash payment to each such employee equal to the amount
accrued on the books and records of FUSB for the benefit of such employee on the
effective date of the Affiliation.  FUSB has agreed to amend each of such
Employee Supplemental Benefit Plan Agreements, prior to the effective date of
the Affiliation, to provide for the cessation of benefit accruals under the
agreements as of such effective date and for the payment of benefits to be made
in a lump sum in the event the agreement is terminated.  As of June 30, 1995, $-
---, $----, and $---- had been accrued under these plans for the benefit of Rosa
Ada Wood, Donna L. Bouslog and William M. Marley, respectively.

  Further, ONB will cause New FUSB or First Citizens to assume FUSB's
obligations (1) to pay health insurance premiums under FUSB's health insurance
plan (or another comparable plan) for Mr. Jim Ross, a former employee of FUSB,
until he attains age sixty-two on September 8, 1995; (2) to pay him $586.85 per
month until his death (with payments guaranteed for not less than a ten year
period beginning January 1, 1991) as a supplement to his retirement benefit
under the defined benefit pension plan sponsored by FUSB to a level which he
would have received had he retired effective December 31, 1995; and (3) to pay
him $1,041.67 per month until December 31, 2000.  This covenant is made on the
condition that the obligations of FUSB being assumed by ONB's affiliate bank
have been fully accrued for on the books and records of FUSB, subject only to an
interest expense with respect to such accrual of $300 per month.

  In connection with effecting the changes from FUSB benefit plans to ONB plans,
FUSB's  Retirement Plan and Employee Stock Ownership Plan will be terminated or
frozen as of December 31, 1995, and  FUSB's Stock Option Plan will be terminated
as of the effective date of the Affiliation.  Benefits under the FUSB Retirement
Plan will be left in trust and payable at the times and in the amounts provided
for under that Plan.  Benefits under the FUSB ESOP will be distributed to
participants in a lump sum or by direct rollover to the ONB Profit Sharing Plan
(without any separate or segregated account for the transferred assets) or into
individual retirement accounts.

INTERESTS OF CERTAIN PERSONS IN THE AFFILIATION

  FUSB and William M. Marley, its President, entered into an employment
agreement in 1986 which was renewed for one additional year on October 30, 1994.
The agreement was amended in connection with the Affiliation to provide that Mr.
Marley will serve as Vice Chairman following the Affiliation and to further
conform his rights to employee benefits to those provided by ONB.  This
agreement currently terminates on March 27, 1998.
 
                                      -15-
<PAGE>
 
  ONB has agreed to assume certain obligations regarding retired officers and
Directors and has, further, agreed to fund the Directors' Supplemental Benefit
Plan Agreements in existence for Directors of FUSB at increased levels for three
years following the effective date, following which it will cease such funding.
In connection with the Affiliation, the Employee Supplemental Benefit Plans for
three FUSB employees, including William M. Marley, will be terminated and all
accrued benefits thereunder will be paid to those employees in a lump sum cash
payment within 10 days following consummation of the Affiliation.  See
"Management, Personnel and Operations after the Affiliation."

  Further, ONB has agreed to provide extended indemnification to the same extent
provided by FUSB at the effective date to directors or officers of New FUSB and
First Citizens who were directors and officers of FUSB or any subsidiaries
against any and all losses in connection with or arising out of any claim which
is based upon any actual or alleged act or omission occurring at or prior to the
effective date.  Indemnification of employees and directors following the
effective date will be provided to the same extent it is provided to individuals
working in similar capacities for ONB or its subsidiaries.  In addition, ONB has
agreed for a period of one year after the effective date to use all reasonable
efforts to cause to be maintained in effect the policies of directors' and
officers' liability insurance maintained by FUSB with respect to claims arising
from facts or events which occurred before the effective date of the
Affiliation.  Following the effective date, ONB will provide FUSB 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 RULING

  ONB and FUSB have requested a private letter ruling from the Internal Revenue
Service ("Service") substantially to the effect that:

  (1)  The acquisition of FUSB stock by ONB Interim Savings Bank in exchange
       solely for voting common stock of ONB and cash for fractional shares will
       qualify as a reorganization within the meaning of Section 368(a)(1)(A)
       and Section 368(a)(2)(E) of the Internal Revenue Code of 1986 (the
       "Code"). ONB, the Interim Savings Bank and FUSB will each be a "party to
       a reorganization" under Section 368(b) of the Code. The sale by FUSB of
       the Greencastle branch in connection with the Asset Purchase will not
       prevent the Affiliation from qualifying as a tax- free reorganization
       under (a) the continuity of interest, (b) the continuity of business
       enterprise or (c) the "substantially all" requirements applicable to tax-
       free reorganizations of this type.

  (2)  The shareholders of FUSB will not recognize any gain or loss on the
       exchange of their FUSB stock solely for ONB voting stock.

  (3)  The Interim Savings Bank will not recognize any gain or loss on its
       receipt of FUSB stock in exchange solely for ONB stock.

                                      -16-
<PAGE>
 
  (4) Each FUSB shareholder's basis in the ONB stock received in the exchange
      will equal the basis of the FUSB stock surrendered therefor.

  (5) Each FUSB shareholder's holding period for the ONB stock received in the
      exchange will include the holding period of the FUSB stock surrendered
      therefor, provided the FUSB stock was held as a capital asset on the date
      of the exchange.

The Service may refuse to rule on all or certain aspects of the private letter
ruling request.  Generally, the Service has taken the position that the Service
will not rule on the tax treatment of a reorganization, even if it is an
integral part of a larger transaction that involves other issues upon which the
Service will rule and it is impossible to determine the tax consequences of the
larger transaction without determining the tax consequences of the
reorganization.  However, the Service has the discretion to rule on significant
subissues that must be resolved to determine whether the transaction qualifies
under Code Section 368(a)(1)(A) (including transactions qualifying by reason of
Code Section 368(a)(2)(E)).

  The ruling issued by the Internal Revenue Service will be based upon the
assumption of certain facts to be stated in the opinion.  Under the Agreement,
the obligations of each of ONB and FUSB to consummate the Affiliation is
conditioned upon the receipt of a tax ruling or a tax opinion from Krieg DeVault
Alexander & Capehart substantially to the effect as set forth above.  In the
event that the Service refuses to rule on the tax-free nature of the
Affiliation, the Boards of Directors of ONB and FUSB have indicated that they
will rely on opinion of counsel to the same effect.

TAX CONSEQUENCES TO ONB AND FUSB

  ONB will acquire the stock of FUSB in exchange for ONB Common Stock.
Consequently, based upon the assumption of certain facts to be stated in the
ruling, the merger of FUSB with ONB should constitute a tax-free reorganization.

TAX CONSEQUENCES TO FUSB SHAREHOLDERS

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

  A FUSB 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, under the provisions of Sections 302(a) and 302(b)(1)
of the Code.

  THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE 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 FUSB SHAREHOLDER.  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

NATURE OF TRADING MARKET

  Shares of ONB Common Stock are traded in the over-the-counter market and share
prices are reported by the NASDAQ National Market System under the symbol OLDB.
On September 29, 1994, the business day immediately preceding the public
announcement of the Affiliation, the closing price of ONB Common Stock reported
by the NASDAQ National Market System was $35.25 per share.  Both of these per
share prices of ONB Common Stock reflect the 5% stock dividend issued by ONB on
February 10, 1995.  The following table sets forth, for the periods indicated,

(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 that FUSB shareholders will not receive in any
     quarter in which the proposed Affiliation is consummated a cash dividend
     from both FUSB and ONB.

EXISTING AND PRO FORMA PER SHARE INFORMATION

  The following table sets forth certain historical, pro forma and equivalent
information, giving effect to the pending affiliations with City National and
Shawnee Bancorp.  The data is based on historical financial statements and the
pro forma financial information included on pages 23 through 29 and has been
restated to give effect to all stock dividends, including the 5% stock dividend
issued by ONB on February 10, 1995.  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 23 affiliate banks located in the
tri-state area comprised of southwestern Indiana and neighboring portions of
Illinois and Kentucky.  With total consolidated assets of $4.4 billion as of
June 30, 1995, ONB is the largest independent bank holding company headquartered
in the State of Indiana.  Since 1985, ONB has acquired 31 financial
institutions, 9 of which were combined with existing affiliate banks, and has
increased its banking offices to 112.

      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 sources of ONB's revenues are
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."

      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.

                              DESCRIPTION OF FUSB

BUSINESS

  FUSB is a federally-chartered, SAIF insured stock savings bank headquartered
in Greencastle, Indiana. In 1986, FUSB converted from a federally-chartered 
mutual association to a federally-chartered stock savings bank through the
issuance of common stock. In 1988, it acquired Fountain Federal Savings Bank of
Bloomington, Indiana and further expanded its market area in 1994 by opening a
loan production office in the Avon area of Danville, Indiana. Currently, FUSB
conducts its business from one office in Greencastle, Indiana, two full service
branches in Bloomington, Indiana, and its loan production office in Danville,
Indiana. It owns two subsidiaries: Greenmark which currently operates as a
property, casualty, life and crop insurance agency and Kirkwood Corporation
which is currently non-operating.

  The principal business of FUSB has always been to accept deposits from the
general public and invest those deposits, together with funds from earnings and
borrowings, primarily in first mortgage loans secured by one to four family
residential properties and, to a lesser extent, in multi-family residential and
consumer loans.

                           REGULATORY CONSIDERATIONS

REGULATION OF ONB AND AFFILIATES

  ONB Regulation.  ONB is registered as a bank holding company and is subject
to the regulations of the Board of Governors of the Federal Reserve System
("Federal Reserve") under the Bank Holding Company Act of 1956, as amended
("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 and its affiliate banks are subject to the Federal Reserve Act, which
restricts financial transactions between banks and affiliated companies.  The
statute limits credit transactions between a depository institution and its
executive officers and its affiliates, prescribes terms and conditions for
affiliate transactions deemed to be consistent with safe and sound banking
practice, and restricts the types of collateral security permitted in
connection with an institution's extension of credit to an affiliate.
 
  Affiliate Regulation.  The affiliate banks of ONB which are national banks
are supervised, regulated and examined by the OCC.  The affiliate banks of ONB,
including First Citizens, 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 Commissioner of Financial Institutions
and those affiliate banks chartered in Illinois are supervised, regulated and
examined by the Illinois Commissioner of Banks and Trust Companies.  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, including First Citizens,  are
supervised and regulated by the FDIC.  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.

                                      -32-
<PAGE>
 
  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.

  Each affiliate of ONB has the power to engage in the business of banking as
provided by the law of its incorporation.  These laws differ from state to
state and from federal law to state law.  However, insured state-chartered
banks are prohibited under FDICIA from engaging as principal in activities that
are not permitted for national banks under federal law, 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.

REGULATION OF FUSB

  General.  As a SAIF-insured savings association, FUSB is subject to
supervision and regulation by the Director of the OTS, as will be New FUSB
following the Affiliation.  Under the OTS regulations, FUSB is required to
obtain audits by independent auditors and to be examined periodically by the
Director of the OTS.  FUSB is subject to assessments by the OTS and the FDIC to
cover the costs of such examinations. The Director of the OTS also is
authorized to promulgate regulations to ensure the safe and sound operations of
savings associations and may impose various requirements and restrictions on
the activities of savings associations.

  The activities of savings associations are governed by the Home Owners' Loan
Act of 1933 ("HOLA") and, in certain respects, the Federal Deposit Insurance
Act, as amended ("FDI Act").

  Qualified Thrift Lender Requirement.  In order for FUSB to exercise the
powers granted to federally-chartered savings associations and maintain full
access to Federal Home Loan Bank  advances, it must be a "qualified thrift
lender"  ("QTL").  A savings institution is a QTL if its qualified thrift
investments continue to equal or exceed 65% of the savings institution's
portfolio assets on a monthly average basis in 9 out of 12 months.  Qualified
thrift investments generally consist of (i) various housing related loans and
investments (such as residential construction and mortgage loans, home
improvement loans, manufactured housing loans, home equity loans and mortgage-
backed securities), (ii) certain obligations of the FSLIC, the FDIC, the FSLIC
Resolution Fund and the Resolution Trust Corporation (for limited periods), and
(iii) shares of stock issued by any Federal Home Loan Bank, the Federal Home
Loan Mortgage Corporation or the Federal National Mortgage Association.

  Liquidity.  Under applicable federal regulations, savings associations are
required to maintain an average daily balance of liquid assets (including cash,
certain time deposits, certain banker's acceptances, certain corporate debt
securities and highly rated commercial paper, securities of certain mutual
funds and specified United States government, state or federal agency
obligations) of not less than 5% of the average daily balance of the savings
association's net withdrawable deposits plus short-term borrowing during the
preceding calendar month.  Under HOLA, this liquidity requirement may be
changed from time to time by the Director of the OTS to any amount within the
range of four percent to ten percent, depending upon economic conditions and
the deposit flows of member institutions.  A savings institution is also
required to maintain an average daily balance of short-term liquid assets of
not less than 1% of the average daily balance of its net withdrawable deposits
and short-term borrowing during the preceding calendar month. At June 30, 1995,
FUSB was in compliance with these liquidity requirements.

                                      -33-
<PAGE>
 
  Loans-to-One-Borrower Limitations.  HOLA generally requires savings
associations to comply with the loans-to-one-borrower limitations applicable to
national banks.  In general, national banks may make loans to one borrower in
amounts up to 15% of the bank's unimpaired capital and surplus, plus an
additional 10% of capital and surplus for loans secured by readily marketable
collateral.  At June 30, 1995, FUSB's loan-to-one-borrower limitation was
approximately $1.5 million.  Under certain OTS regulations, a savings
institution may make loans to one borrower for residential housing developments
in amounts up to 30% of the bank's unimpaired capital and surplus upon prior
notice to and approval of the OTS and provided that all loans made in reliance
upon the increased lending limit do not, in the aggregate, exceed 150% of the
bank's unimpaired capital and surplus.  At June 30, 1995, FUSB had one loan
made under this higher lending limit and one loan which was in excess of the
15% lending limit, but had been grandfathered.

  Commercial Real Property Loans.  HOLA limits the aggregate amount of
commercial real estate loans that a federal savings institution may make to an
amount not in excess of 400% of the savings institution's capital.

  FUSB's Subsidiaries.  The OTS regulations permit federal savings associations
to invest in the capital stock, obligations or specified types of securities of
subsidiaries (referred to as "service corporations") and to make loans to such
subsidiaries and joint ventures in which such subsidiaries are participants in
an aggregate amount not exceeding three percent of an institution's assets,
provided any investment over two percent is used for specified community or
inner-city development purposes.  In addition, federal regulations permit
institutions to make specified types of loans to such subsidiaries, in which
the institution owns more than ten percent of the stock, in an aggregate amount
not exceeding 50% of the institution's regulatory capital if the institution's
investment is in compliance with applicable loans-to-one-borrower regulations.
A savings institution which acquires a non-savings institution subsidiary, or
which elects to conduct a new activity within a subsidiary, must give the FDIC
and the OTS at least 30 days' advance written notice.  The FDIC may, after
consultation with the OTS, prohibit specific activities if it determines such
activities pose a serious threat to SAIF.  FUSB has two such subsidiaries,
Greenmark and Kirkwood Corporation.

  Branching.  The rules of the OTS on branching by federally-chartered savings
associations permit nationwide branching to the extent allowed by federal
statute.  This permits federal savings associations with inter-state networks
to diversify their loan portfolio and lines of business.  The OTS authority
pre-empts any state law purporting to regulate branching by federal savings
associations.

CAPITAL ADEQUACY GUIDELINES

  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

                                      -34-
<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 are ONB's regulatory capital ratios as of June 30, 1995:

         Tier 1 Capital:                      13.49%

         Total Capital:                       15.79%

         Leverage Ratio:                        8.6%

  Depository institution affiliates of ONB and FUSB are required to meet
similar capital adequacy ratios.  The FDIC, OCC and OTS have adopted risk-based
capital ratio guidelines to which depository institutions 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.

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

  In addition, the agencies established guidelines prescribing a minimum Tier 1
leverage ratio of 3% for depository institutions that meet certain specified
criteria, including that they have the highest regulatory rating and are not
experiencing or anticipating significant growth.  All other institutions 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 FUSB exceed the risk-based capital
guidelines as of June 30, 1995.

  Effective September 1, 1995, the OCC, the Federal Reserve and the FDIC
amended their capital standards to specify that the banking agencies will
include, in their evaluations of a bank's capital adequacy, an assessment of
its exposure to declines in the economic value of the bank's capital due to
changes in interest rates.  Concurrently, these banking agencies issued for
comment a joint policy statement describing the process the banking agencies
will use to measure and assess the exposure of a bank's net economic value to
changes in interest rates.  The information and exposure estimates collected
through this new proposed supervisory measurement process will be one
quantitative factor used by examiners to determine the adequacy of an
individual bank's capital for interest rate risk.  Other quantitative factors
that examiners will consider include the bank's historical financial
performance and its earnings exposure to interest rate movements.  Examiners
will also consider qualitative factors, including the adequacy of the bank's
internal interest rate risk management.

  After the banking agencies and banking industry gain sufficient experience
with the proposed measurement process, the banking agencies intend, through a
subsequent rulemaking process, to issue a

                                      -35-
<PAGE>
 
proposed rule that would establish an explicit capital charge for interest rate
risk that will be based upon the level of a bank's measured interest rate risk
exposure.

  The proposed interagency supervisory policy statement requires certain banks
to submit new interest rate risk consolidated reports of condition and income,
or call report, schedules beginning in March 1996, indicating the maturity,
repricing or price sensitivity of their various on- and off-balance-sheet
instruments. A bank would also have the option of reporting its internal market
estimates of the price sensitivity of its major portfolios and its net economic
value.  Banks with assets under $300 million, composite CAMEL supervisory
ratings of 1 or 2, and moderate or low holdings of assets with intermediate-and
long-term maturity or repricing characteristics would be exempt from expanded
reporting requirements.

  The supervisory model would apply a series of interest rate risk weights to a
bank's reported repricing and maturity balances.  The risk weights estimate
price sensitivity of a bank's reported balances to a 200 basis-point change in
interest rates.  The summation of these weighted balances, along with certain
price sensitivity information that a bank may be required to report, results in
a net risk-weighted exposure for the institution.  That exposure represents the
estimated change in the bank's economic value to the specified change.  Full
implementation of the proposed supervisory policy statement for assessing the
adequacy of bank capital for interest rate risk would occur on December 31,
1996.

  It is too early to assess the impact, if any, these new rules and proposals
will have on ONB or its subsidiaries.

BRANCHING AND ACQUISITIONS

  Branching.  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, of the Indiana Department of Financial Institutions, Kentucky
Department of Financial Institutions or Illinois Commissioner of Banks and
Trust Companies (depending upon the location of the principal office of the
bank).  Under current law, branches may be established by banks in Illinois and
Indiana throughout the state; whereas in Kentucky, branches may only be
established in the home county of the bank.  As discussed below, Congress
recently authorized interstate branching, with certain limitations, beginning
in 1997.

  Acquisitions.  Bank  holding companies, such as ONB, are  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.
The BHC Act also currently prohibits ONB from acquiring control of any bank
operating outside the State of Indiana unless such action is specifically
authorized by the statutes of the state where the bank to be acquired is
located.  That prohibition will no longer be applicable as of September 29,
1995, as discussed below.  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.

  The BHC Act specifically authorizes a bank holding company, upon receipt of
appropriate approvals from the Federal Reserve and the Director of the OTS, to
acquire control of any savings association or

                                      -36-
<PAGE>
 
holding company thereof wherever located.  Similarly, a savings and loan
holding company may acquire control of a bank.  A savings association acquired
by a bank holding company cannot continue any non-banking activities not
authorized for bank holding companies.  For this reason, Greenmark must be
purchased by First Citizens, which may legally preserve most of its insurance
agency powers.  Savings associations acquired by a bank holding company may, if
located in a state where the bank holding company is legally authorized to
acquire a bank, be converted to the status of a bank, but deposit insurance
assessments and payments continue to be paid by the association to the Savings
Association Insurance Fund ("SAIF").  A savings association so converted to a
bank becomes subject to the branching restrictions applicable to banks.  Also,
any insured depository institution may merge with, acquire the assets of, or
assume the liabilities of any other insured depository institution with the
appropriate regulatory approvals if (i) continued payments of deposit insurance
premiums are made on the acquired depository institution's deposits (including
an assumed rate of growth in such deposits) to SAIF (if the acquired
institution was a SAIF member) or to the Bank Insurance Fund ("BIF") (if the
acquired institution was a BIF member), (ii) the acquiring institution and any
holding company in control thereof meet all applicable capital requirements at
the time of the transaction, and (iii) if the acquiring institution is a BIF
member, the transaction meets any limitations on geographic expansion.

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, 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.

  Beginning on September 29, 1995, an insured bank subsidiary may act as an
agent for an affiliated bank or savings association 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.

FDICIA

  FDICIA accomplished a number of sweeping changes in the regulation of
depository institutions. 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 capital ratio of 10% or
greater, a

                                      -37-
<PAGE>
 
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, and generally a leverage ratio 4% or greater.  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 case 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.

  FDICIA further directs that each federal banking agency prescribe standards
for depository institutions and depository institution holding companies
relating to internal controls, information systems, internal audit systems,
loan documentation, credit underwriting, interest rate exposure, asset growth,
management compensation, a maximum ratio of classified assets to capital,
minimum earnings sufficient to absorb losses, a minimum ratio of market value
to book value of publicly traded shares and such other standards as the agency
deemed appropriate.

DEPOSIT INSURANCE

  The deposits of ONB's affiliate banks are insured up to $100,000 per insured
account, by the BIF, except for deposits acquired in connection with
affiliations with savings associations, which deposits are insured by the SAIF.
Accordingly, ONB pays deposit insurance premiums to both BIF and SAIF and will
continue to pay SAIF premiums with respect to all deposits of FUSB acquired in
the Affiliation.  If the FDIC believes that an increase in the insurance rates
is necessary, it may increase the insurance premiums applicable to BIF or SAIF.
Currently SAIF premiums are significantly higher than BIF premiums; however,
Congress is considering a number of alternatives to address this issue and
maintain relative equality among premium payments, including a large one-time
assessment on savings associations, requiring banks to help finance the bonds
issued to recapitalize the thrift industry, and merging SAIF and BIF.   Some
Congressional proposals also require savings associations to convert to bank
charters.  It is difficult at this time to assess whether Congress will address
the SAIF/BIF premium differential and, if so, what impact its legislative
solution to that problem will have on ONB and its subsidiaries, FUSB, or New
FUSB.

  Effective January 1, 1993, the FDIC adopted a final rule that implements a
transitional risk-based assessment system whereby a base insurance premium will
be adjusted according to the capital category

                                      -38-
<PAGE>
 
and subcategory of an institution to one of three capital categories consisting
of (1) well capitalized, (2) adequately capitalized, or (3) undercapitalized,
and one of three subcategories consisting of (a) health, (b) supervisory
concern, or (c) substantial supervisory concern.  An institution's assessment
rate will depend upon the capital category and supervisory category to which it
is assigned.  Assessment rates for banks range from .04% for an institution in
the highest category (i.e., well capitalized) to 0.31% for an institution in
the lowest category (i.e. undercapitalized and substantial supervisory
concern), and for savings associations range from .23% for well capitalized
institutions to .31% for institutions in the lowest category. The supervisory
subgroup to which an institution is assigned by the FDIC is confidential and
may not be disclosed.  Deposit insurance assessments may increase depending
upon the category and subcategory, if any, to which the bank is assigned by the
FDIC.  Any increase in insurance assessments could have an adverse effect on
the earnings of ONB's affiliate banks.

RECENT LEGISLATION

  Congress is currently considering two pieces of proposed legislation which
would impact financial institutions.  The first such bill, the Financial
Services Competitiveness Act, seeks to repeal the Glass-Steagall Act which has
severely limited the ability of financial institutions to underwrite securities
since immediately after the Depression.  Should this bill be enacted in its
form as of the date of this Proxy Statement, it would expand the securities
powers of bank holding companies, like ONB, permitting them to form a
subsidiary to underwrite and deal in securities and debt instruments.  ONB
currently may act as a broker/dealer for securities (as it does through its
affiliate ONB Investment Services), but it may not generally underwrite
corporate securities or debt.  The effect of the bill would also be to permit
bank holding companies to acquire, and be acquired by, securities firms.

  The second bill, the Financial Institutions Relief Act, would scale back
certain laws which are deemed by Congress to impose regulatory burdens on banks
and would eliminate redundancies in the law.  Included in the affected laws are
the Truth-in-Savings Act, the Community Reinvestment Act and certain laws with
respect to disclosures in mortgage lending and the like.

  The progress of both of these bills is currently suspended while Congress
determines what, if any, provisions regarding insurance powers should be
included.  The extent of the ability of banks to sell insurance is highly
controversial, involving two powerful trade groups with a history of
intractability.  The insurance issue could halt permanently the attempts to
obtain either Glass-Steagall relief or regulatory relief.

  It cannot be predicted with certainty whether such legislation will be
enacted or the extent to which the banking industry in general, or ONB and its
affiliate banks in particular, would be affected.

ADDITIONAL MATTERS

  In addition to the matters discussed above, ONB's affiliate banks and FUSB
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

                                      -39-

<PAGE>
 
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 affiliates 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 may be considered by 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 ONB and its
affiliate banks in particular would be affected thereby.

                           COMPARISON OF COMMON STOCK

  The rights of holders of FUSB 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 FUSB shareholders are presently governed by
federal law applicable to savings associations and by FUSB's Charter and By-
Laws.  The rights of FUSB shareholders differ in certain respects from the
rights they would have as ONB shareholders, including for ONB 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 FUSB
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
of Incorporation and By-Laws and the Charter and By-Laws of FUSB.

AUTHORIZED BUT UNISSUED SHARES

  ONB's Articles of Incorporation authorize the issuance of 30,000,000 shares
of ONB Common Stock, of which 22,890,065 whole shares were outstanding as of
June 30, 1995.  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 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 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 ("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 "Anti-Takeover Provisions 
-- ONB's Shareholder Rights Plan" below.

                                      -40-
<PAGE>
 
   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 June 30, 1995, ONB had 1.4 million shares of ONB Common Stock reserved
 for issuance under ONB's dividend reinvestment and stock purchase plan and 1.5
 million shares of its common stock reserved for issuance upon conversion of its
 outstanding 8% convertible subordinated debentures.  Such debentures are
 convertible at any time prior to maturity, unless previously redeemed, into
 shares of ONB Common Stock at a conversion rate of 42.517 shares per $1,000
 principal amount of debentures (equivalent to a conversion price of
 approximately $24.70 per share), subject to adjustment in certain events.

   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.

   The Charter of FUSB authorizes the issuance of 5,000,000 shares of FUSB
 Common Stock, $.01 par value per share, of which 546,550 shares were issued and
 outstanding as of September 8, 1995, and options for 35,650 shares, which must
 be exercised prior to the effective date of the Affiliation, were outstanding
 on that date.  Following the Affiliation, all of the outstanding shares of FUSB
 Common Stock will be held by ONB.

   FUSB has 2,000,000 shares of Preferred Stock, $1 par value, authorized, of
 which none are issued. Such shares are available to be issued without
 shareholder approval under the Charter of FUSB; however, pursuant to the
 Agreement, FUSB is restricted in issuing such shares.

 PREEMPTIVE RIGHTS

   Neither ONB's nor FUSB's shareholders have preemptive rights to subscribe for
 any new or additional ONB Common Stock or FUSB Common Stock, respectively, or
 other securities.

 DIVIDEND RIGHTS

   The holders of common stock of ONB are entitled to dividends and other
 distributions when, as and if declared by its Board of Directors out of funds
 legally available therefor. A dividend may not be paid by ONB if, after giving
 it effect, (1) ONB would not be able to pay its debts as they become due in the
 usual
 
                                      -41-
<PAGE>
 
 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.

   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 and
 the Bank 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.

   The OTS regulations impose limitations on capital distributions by savings
associations, including FUSB. Under the rule, a savings institution is
classified as a tier 1 institution, a tier 2 institution, or a tier 3
institution, depending on its level of regulatory capital both before and after
giving effect to a proposed capital distribution. A tier 1 institution may
generally make capital distributions in any calendar year up to 100% of its net
income to date during the calendar year plus the amount that would reduce by
one-half its "surplus capital ratio" (i.e., the percentage by which the
institution's capital-to-assets ratio exceeds the ratio of its capital
requirements to its assets) at the beginning of the calendar year. No regulatory
approval of the capital distribution is required, but prior notice must be given
to the OTS. Restrictions exist on the ability of tier 2 and tier 3 institutions
to make capital distributions. For purposes of this regulation, FUSB is a tier--
institution.

   Dividends paid by ONB's affiliate banks and FUSB 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 nor FUSB is currently subject to such a restriction.

VOTING RIGHTS

   The holders of the outstanding shares of ONB Common Stock and FUSB Common
Stock are entitled to one vote per share on all matters presented for
shareholder vote.  ONB shareholders do not have cumulative voting rights in the
election of directors.  FUSB shareholders have the right to cumulative voting in
the election of Directors. See "GENERAL INFORMATION" and "ELECTION OF FUSB
DIRECTORS."

                                      -42-
<PAGE>
 
  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 of a majority 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.  See "-- Anti-Takeover Provisions."  The
laws applicable to FUSB require a two-thirds vote of shareholders to approve
mergers and consolidations.

  Indiana law requires shareholder approval for most amendments to a
corporation's articles of incorporation -- under Indiana law, 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.  Amendments to FUSB's Charter must be approved by a
majority vote of shareholders.

DISSENTERS' RIGHTS

  The holders of FUSB Common Stock and ONB Common Stock possess no dissenters'
rights in connection with the Affiliation.  ONB shareholders would not have
dissenters' rights for any future merger or acquisition so long as ONB Common
Stock is traded on the NASDAQ National Market System.

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 FUSB, the holders of shares of FUSB 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 FUSB
liabilities, any rights of creditors and rights of any holders of FUSB preferred
stock then outstanding.

ASSESSMENT AND REDEMPTION

  Shares of ONB Common Stock and FUSB Common Stock are not liable to further
assessment. 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.

  In addition, ONB must give prior notice to the Federal Reserve if the
consideration to be paid by them for any redemption or acquisition of their
respective shares, when aggregated with the consideration paid
 
                                      -43-
<PAGE>
 
for all redemptions or acquisitions for the preceding twelve (12) months, equals
or exceeds 10% of their respective consolidated net worth.

  Stock redemptions by FUSB would be deemed made by FUSB from its tax bad debt
reserve and would result in adverse tax consequences to FUSB.  Moreover, FUSB
may not repurchase any of its capital stock if the effect thereof would cause
the net worth of the stock to be reduced below the amount required for its
liquidation account.  For a description of certain OTS limitations on FUSB's
ability to repurchase its shares, see "Comparison of Common Stock - Dividend
Rights."

ANTI-TAKEOVER PROVISIONS

  The anti-takeover measures applicable to ONB, 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.  These measures may have the effect of
discouraging certain tender offers for shares of ONB 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 Securities and 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 date of
the election.  ONB is covered by the business combinations provision of Indiana
law.

  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 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 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, as Trustee, which is
specifically incorporated herein by reference. See "INCORPORATION OF CERTAIN
DOCUMENTS BY REFERENCE."

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 position would
exercise under similar circumstances and in a manner the director reasonably
believes to be in the best interests of the corporation and (2) such breach or
failure to perform constitutes willful misconduct or recklessness.  There is no
similar provision applicable to FUSB under federal law.

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.

  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
 
                                      -45-
<PAGE>
 
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 Annual Meeting of shareholders at which directors will be elected.

  With respect to FUSB, the Chairman of the Board of Directors is required by
the bylaws to appoint a Nominating Committee consisting of the Board of
Directors or a committee of the Board of Directors of not less than three
members.  Such committee is authorized to make nominations for Directors in
writing to the Secretary of FUSB at least twenty days prior to the Annual
Meeting, which nominations are then posted at FUSB's office.  Nominations for
Directors may also be made in writing by shareholders and delivered to the
Secretary of FUSB at least five days prior to the Annual Meeting.


                                 ELECTION OF FUSB DIRECTORS

NOMINEES AND DIRECTORS

  The Board of Directors of FUSB is currently composed of six members.  FUSB's
bylaws provide that the Directors shall be divided into three classes as nearly
equal in number as possible.  Directors of FUSB are generally elected to serve
for a three-year period or until their respective successors are elected and
qualified.  The nominees for Director this year are Earl E. Clodfelter and
William M. Marley, each of whom is a current Director of FUSB.  If elected by
the Shareholders at the Annual Meeting, Messrs. Clodfelter and Marley will serve
as Directors of FUSB until 1998, subject to earlier termination upon
consummation of the Affiliation.  Following the Affiliation, they will serve as
Directors of First Citizens in accordance with the bylaws of First Citizens,
which provide that Directors serve one year terms.

  The following table sets forth certain information regarding each nominee for
election as a Director and each Director continuing in office after the Annual
Meeting.  It is intended that the proxies solicited on behalf of the Board of
Directors (other than proxies as to which authorization is withheld) will be
voted at the Annual Meeting for the election of the nominees identified below.
If any Director nominee is unable or declines to serve (an event which the Board
of Directors does not anticipate), the proxies will have discretionary authority
to vote for a substitute nominee named by the Board of Directors if the Board
elects to fill such nominee's position.  The table also sets forth the number of
shares of FUSB Common Stock beneficially owned by all Directors and executive
officers of FUSB as a group.

EMPLOYMENT AGREEMENT

  The Board of Directors has approved a three-year employment contract with its
President and Chief Executive Officer, William M. Marley. The contract can be
extended for additional one-year terms to maintain a three-year term unless
notice is properly given by either party to the contract. Unless extended
further, the contract will expire in 1997. Mr. Marley receives his current
salary under the contract, which salary is subject to increases approved by the
Board of Directors. The contract also provides, among other things, for
participation in other fringe benefits and benefit plans available to FUSB
employees. Mr. Marley may terminate his employment upon 30 days' written notice
to FUSB. FUSB may discharge Mr. Marley for "cause" (as defined in the contract)
at any time or in certain events specified by Office of Thrift Supervision
("OTS") regulations. Upon termination of Mr. Marley's employment by FUSB for
other than cause or in the event of termination by Mr. Marley "for cause" (as
defined in the contract), Mr. Marley will receive his base compensation under
the contract (a) for an additional three years (or the remaining term of the
contract, if shorter) if the termination follows a change of control (as defined
in the contract), or (b) for an additional two years (or the remaining term of
the contract, if shorter) if the termination does not follow a change of
control. In addition, during such period, Mr. Marley will continue to
participate in FUSB's group insurance plans or receive comparable benefits.
Moreover, within a period of three months after such termination following a
change of control, Mr. Marley will have the right to cause FUSB to purchase any
stock options he holds for a price equal to the fair market value (as defined in
the contract) of the shares subject to such options minus their option price.
Payments pursuant to the contract may trigger adverse tax consequences to FUSB
and Mr. Marley under the so-called "golden parachute" provision of the Internal
Revenue Code of 1986, as amended (the "Code").

  The employment contract provides FUSB protection of its confidential
business information and protection from competition by Mr. Marley should he
voluntarily terminate his employment without cause or be terminated by FUSB for
cause.

COMPENSATION OF DIRECTORS

  Each Director (including Directors who are also employees) of FUSB
receives a monthly honorarium of $250 and an additional fee of $500 for each
monthly Board meeting attended by him.  Directors are not reimbursed for
expenses incurred in attending meetings.  There are no fees paid for attendance
at Board committee meetings.  Directors are also entitled to receive stock
options under FUSB's Stock Option Plan.

  In addition, FUSB has adopted a supplemental benefit plan which provides each
of FUSB's Directors with supplemental benefits after the Director ceases to be a
member of the Board, attains age 65, or upon death. The retirement benefits
payable for a period of 120 months are equal to the balance of the Director's
account under the Plan; provided that for Directors on the Board as of June 30,
1993, who serve until age 65, the minimum monthly benefit is $650. The
Director's account consists of all amounts accrued under FUSB's prior
supplemental benefit plan for Directors as of June 30, 1993, plus $350 per month
consisting of fees deferred by the Director while on the Board. Interest equal
to the United States Treasury Bill two years interest rate in effect as of the
last business day of each month is credited to the balance of such accounts.
Death benefits are also payable under the plan. Except in the event of a change
of control, Directors must serve for five years in order to receive the
retirement benefits provided under the plan.

                                      -50-

TRANSACTIONS WITH CERTAIN RELATED PERSONS

  FUSB has followed the policy of offering loans to its Directors, officers and
employees for the financing of their principal residences and for other personal
loan purposes, including overdraft and credit card lines of credit. All such
loans made since the adoption of the Financial Institutions Reform, Recovery and
Enforcement Act of 1989 and all such loans in excess of $60,000 were made in the
ordinary course of business on substantially the same terms and collateral as
those of comparable transactions prevailing at the time and do not involve more
than the normal risk of collectibility or present other unfavorable features.

  The law firm of Andrews, Harrell, Mann, Chapman & Coyne, of which Harold A.
Harrell is a partner, rendered legal services during the year ended June 30,
1995, to FUSB, and it is expected that the firm will continue to do so in the
next fiscal year. The legal services were rendered in the ordinary course of
business and the amount of fees paid to the law firm by FUSB did not exceed 5%
of the firm's gross revenues for the firm's last full fiscal year.

                                    OPINIONS

                                  ----------

                                   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 Savings
Bank Common Stock (as hereinafter defined), except for the 1,000 shares of
Savings Bank Common Stock held by Greenmark, Inc. which shall be canceled as of
the Effective Time, shall be converted into the right to receive eighty-five one
hundredths (0.85) of a share of ONB common stock ("Exchange Ratio"), subject to
adjustment, if any, as set forth in Sections 2.01(b) and 2.03 hereof.  Upon and
by virtue of the Merger becoming effective at the Effective Time, each issued
and outstanding share of Interim Thrift capital stock shall be converted into an
equal number of shares of common stock of the Surviving Thrift.

     (b) If the Average Price Per Share (as hereinafter defined) of ONB common
stock is more than ten percent (10%) above or below $36.50, then the Exchange
Ratio shall be adjusted in accordance with this subsection.  Accordingly, if the
Average Price Per Share of ONB common stock exceeds $40.15, then the Exchange
Ratio shall be adjusted such that each issued and outstanding share of Savings
Bank Common Stock shall be converted into the right to receive a fraction of a
share of ONB common stock determined by dividing $34.1275 by the Average Price
Per Share of ONB common stock.  Similarly, if the Average Price Per Share of ONB
common stock is less than $32.85, then the Exchange Ratio shall be adjusted such
that each issued and outstanding share of Savings Bank Common Stock shall be
converted into the right to receive a fraction of a share of ONB common stock
determined by dividing $27.9225 by the Average Price Per Share of ONB common
stock.  If the Average Price Per Share of ONB common stock is not less than
$32.85 or not more than $40.15, then there shall be no adjustment to the
Exchange Ratio.

     (c) The "Average Price Per Share" of ONB common stock shall 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 shares of ONB common stock are traded within the ten (10) calendar days
immediately preceding the Effective Time.

     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 Savings Bank who would
otherwise have been entitled to a fraction of a share of ONB common stock shall
be paid in cash 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, ONB distributes or issues a stock dividend with respect to its
shares of common stock, or combines, subdivides, reclassifies or splits up its
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 Savings Bank'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

                                      A-3

<PAGE>
 
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) Immediately
following the Effective Time, ONB shall mail to each Savings Bank shareholder a
letter of transmittal providing instructions as to the transmittal to ONB of
certificates representing shares of Savings Bank 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, ONB shall distribute stock certificates
representing shares of ONB common stock and any cash payment, without interest,
for fractional shares, if any, to each former shareholder of Savings Bank within
ten (10) business days following delivery to ONB of the shareholder's
certificates representing such shareholder's shares of Savings Bank Common Stock
accompanied by a properly completed and executed letter of transmittal, all in
form and substance reasonably satisfactory to ONB and Savings Bank.

     (c) Following the Effective Time, stock certificates representing Savings
Bank Common Stock shall be deemed to evidence ownership of ONB common stock for
all corporate purposes; provided, however, that no dividends or other
distributions otherwise payable subsequent to the Effective Time on shares of
ONB common stock shall be paid to any Savings Bank shareholder entitled to
receive the same until such shareholder has surrendered to ONB his or her
certificate or certificates representing Savings Bank Common Stock in exchange
for a certificate representing ONB common stock.  Upon surrender of the
certificates representing shares of Savings Bank Common Stock, there shall be
paid in cash to the record holder of the new certificate 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 Savings
Bank to establish the persons entitled to receive shares of ONB common stock
pursuant to this Agreement, which books, in the absence of actual knowledge by
ONB of any adverse claim thereto, shall be conclusive with respect to the
ownership of shares of Savings Bank Common Stock.

     (e) With respect to any certificate for shares of Savings Bank Common Stock
which has been lost, stolen or destroyed, ONB shall be authorized to issue its
common stock (and to pay cash for fractional shares) to the registered owner of
such certificate upon ONB's receipt of an agreement to indemnify ONB against
loss with respect to 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 Savings Bank
shareholder with all other reasonable requirements of ONB in connection with
lost, stolen or destroyed stock certificates.


                                   SECTION 3

                            DISSENTING SHAREHOLDERS
                            -----------------------

     Shareholders of Savings Bank are not entitled to statutory dissenters'
rights since Savings Bank Common Stock is listed on NASDAQ.  Savings Bank shall
take no action which would result in the loss of such listing on NASDAQ prior to
the Effective Time.

Savings Bank, whether individually or on a consolidated basis, or which would
prevent the performance of this Agreement, declare the same unlawful or cause

other facts, which inclusion or omission would render any of the Savings Bank
Financial Statements false, misleading or inaccurate in any material respect as

                     either of the Subsidiaries to or for the benefit of each
                     such person for the calendar years ended December 31, 1993
                     and 1994, and any employment, severance or deferred

letter of credit, line of credit, loan transaction, loan agreement, promissory
note or other commitment of Savings Bank, in excess of $10,000 individually or
in the aggregate, whether in principal, interest or otherwise, and including all
guarantors of such indebtedness; and

          (c) To the best knowledge of Savings Bank, each of the agreements,
contracts, commitments, leases, instruments and documents set forth in the
Disclosure Schedule relating to this Section 4.09 is valid and enforceable in
accordance with its terms.  Savings Bank is and, to its best knowledge, all
other parties thereto are in compliance with the provisions thereof, and Savings
Bank is not and, to its best knowledge, no other party thereto is in default in
the performance, observance or fulfillment of any 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.

          4.10.  Absence of Undisclosed Liabilities.  Except as set forth in the
Disclosure Schedule, except as provided in the Savings Bank Financial
Statements, except for accounts payable incurred and unfunded loan commitments
made to customers in the ordinary course of business, except for additional
borrowings from the Federal Home Loan Bank of Indianapolis incurred in the
ordinary course of business between the date hereof and the Effective Time and
except for the transactions contemplated by the Purchase and Assumption
Agreement, neither Savings Bank nor either of the Subsidiaries has any

all other real estate owned) which is reflected in the Savings Bank Financial
Statements as of June 30, 1994; good and marketable title to all personal
property reflected in the Savings Bank Financial Statements as of June 30, 1994,
other than personal property disposed of in the ordinary course of business

Savings Bank uses in its business; and good and marketable title to, or right to
use by valid and enforceable lease, all property and assets acquired and not
disposed of or leased, as the case may be, since June 30, 1994.  All of such
properties and assets owned by Savings Bank are owned free and clear of all land
or conditional sales contracts, mortgages, liens, pledges, restrictions,
security interests, charges, claims, rights of third parties or encumbrances of
any nature except (i) as set forth in the Disclosure Schedule; (ii) as
specifically noted in reasonable detail in the Savings Bank 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, minor imperfections of title,
building or use restrictions, variations and other limitations which are not
substantial in amounts, 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 Savings Bank
is in material compliance with all applicable zoning and land use laws.

          (b) To the best of Savings Bank's knowledge, Savings Bank 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 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 all 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 Savings Bank, threatened claims, actions or proceedings by any
sewage district or other federal, state or local governmental agency or
authority against Savings Bank with respect to any of the Environmental Laws
and, to the best of Savings Bank's knowledge, there is no basis or grounds for
any such claim, action or proceeding.  No environmental clearances or other
governmental environmental approvals are required for the conduct of Savings
Bank's business or consummation of the Merger.  To the best of Savings Bank's
knowledge, Savings Bank is not 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 some other remedial action under any of the Environmental Laws.

          (c) Savings Bank (i) is not in default in any respect under any
agreements pursuant to which it leases real or personal property, (ii) has no
knowledge of any default under such agreements by any party thereto and (iii)
has no knowledge of any event which, with notice or lapse of time or both, would
constitute a default or a breach thereof.

          4.12.  Loans and Investments.  (a) Except as set forth in the
Disclosure Schedule, Savings Bank has no loan in excess of $10,000 that has been
classified by management as "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 Savings Bank and a list of all loans in excess of $10,000
that Savings Bank has determined to be ninety (90) 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 Savings Bank Financial Statements as of
June 30, 1994 and which have been made, extended, renewed, restructured,
approved, amended or acquired since June 30, 1994 (i) have been made for good,
valuable and adequate consideration in the ordinary course of business; (ii) to
the best of Savings Bank's knowledge, 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 Savings Bank has a
security interest in collateral or a mortgage securing such loans, by perfected
security interests or recorded mortgages naming Savings Bank as the secured
party or mortgagee.

          (c) Except as set forth in the Disclosure Schedule, the reserves, the
allowance for possible loan and lease losses and the carrying value for real
estate owned which are shown on the Savings Bank Financial Statements are, in
the opinion of management of Savings Bank, adequate in all 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 Savings Bank, the aggregate loan balances outstanding
as of June 30, 1994, in excess of the reserve for loan losses as of such date,
are collectible in accordance with their respective terms.

          (d) None of the investments reflected in the Savings Bank Financial
Statements as of and for the period ended June 30, 1994 and none of the
investments made by Savings Bank since June 30, 1994 are subject to any
restriction, whether contractual or statutory, which materially impairs the
ability of Savings Bank to dispose freely of such investment at any time.
Savings Bank 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 Savings Bank has any participation interest
or which have been made with or through another financial institution on a
recourse basis against Savings Bank.

          (f) The aggregate amount of Savings Bank's indebtedness to the Federal
Home Loan Bank of Indianapolis does not, and will not at the Effective Time,
exceed $20 Million.

          4.13.  Anti-takeover Provisions.  Savings Bank has no shareholder
rights plan or any other plan, program, agreement or provision involving,
restricting, prohibiting or discouraging a change in control,

employee benefit plans.

          4.14.  Employee Benefit Plans.  (a) With respect to the employee

been timely received from the Internal Revenue Service ("Service") with respect
to each such Savings Bank Plan stating that each, in its current form (or at the

Code and Treasury Regulations, except that determination letters relating to the

any stock of a related or affiliated person or entity, except as provided in the
Disclosure Schedule; (iv) Savings Bank has no liability to the Department or the

Code) has occurred with respect to any Savings Bank Plan; (vii) each Savings

the Code has been and, if applicable, is being operated in accordance with the
applicable provisions of ERISA and the Code and the Department and Treasury

required to be performed by Savings Bank under any provision of a Savings Bank
Plan have been performed by it and it is not in default under or in violation of
any provision of a Savings Bank Plan; (x) no event has occurred which would
constitute grounds for an enforcement action by any party under Part 5 of Title
I of ERISA under any Savings Bank Plan; and (xi) there are no actions, suits,

the best knowledge of Savings Bank, threatened against Savings Bank, any Savings

under Section 401(a) of the Code, to the best knowledge of Savings Bank, no
director, officer, employee or agent of Savings Bank has engaged in any action
or failed to act in such a manner that, as a result of such action or failure to
act, (i) the Service could revoke or deny that plan's qualification under
Section 401(a) of the Code or the exemption under Section 501(a) of the Code for
any trust related to such Plan or (ii) a participant or beneficiary or a non-
participating employee has been denied any benefit due or to become due under

Savings Bank Plan.

          (c) Savings Bank has provided to ONB in the Disclosure Schedule true,
accurate and complete copies or summaries and, in the case of any plan or
program which has not been reduced to writing, a

                                      A-13

          (b) Neither the execution of this Agreement nor consummation of the
Merger (i) conflicts with or violates ONB's Articles of Incorporation or By-Laws
or Interim Thrift's Charter or By-Laws; (ii) conflicts with or violates any
local, state, federal or foreign law, statute, ordinance, rule or regulation

          5.03.  Capitalization.  (a) The authorized capital stock of ONB as of
the date of this Agreement consists of (i) 30,000,000 shares of common stock, no
par value per share, of which approximately 19,284,182 shares were issued and
outstanding as of June 30, 1994, and (ii) 2,000,000 shares of preferred stock,
no shares of which have been or are presently intended to be issued, other than

its shareholders' rights plan.  Such issued and outstanding shares of ONB common
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

outstanding convertible subordinated debentures, (iii) acquisitions by ONB of
other financial institutions or holding companies, and (iv) ONB's restricted

commitments, calls, puts, agreements, understandings, arrangements or
subscription rights relating to any shares of ONB common stock, or any
securities convertible into or representing the right to purchase or otherwise
acquire any common stock or debt securities of ONB, by which ONB is or may
become bound.  ONB does not have any contractual or other obligation to
repurchase, redeem or otherwise acquire any of its issued and outstanding shares
of common stock.

          (c) 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 effect as of the date of this Agreement have been delivered to
Savings Bank 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.
Each of ONB and its subsidiaries possesses and holds all licenses, franchises,
permits, certificates and other authorizations necessary for the continued
conduct of its business without interference or interruption.

("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 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 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, or which would prevent the performance
of this Agreement, declare the same unlawful or cause the rescission hereof.

          (b) Neither ONB nor any of its subsidiaries is (i) subject to any
outstanding judgment, order, writ, injunction or decree of any court,

              (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, 1991, 1992 and 1993 and as of and
                      for the periods ended June 30, 1993 and 1994; and

              (ii)    Consolidated statements of cash flows of ONB for the years
                      ended December 31, 1991, 1992 and 1993 and for the periods
                      ended June 30, 1993 and 1994.

          (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 (a)(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, 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 the Merger.  The shares of ONB common
stock which Savings Bank 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

the Merger is not required.

or incurred any obligation, agreement, contract, commitment, liability, lease or
license 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.

          5.12.  Environmental Matters.  To the best of ONB's knowledge, each of
ONB's subsidiaries has conducted its business in compliance with the
Environmental Laws.  There are no pending or, to the best knowledge of ONB,
threatened claims, actions or proceedings by any sewage district or other
federal, state or local governmental agency or authority against any of ONB's
subsidiaries with respect to any of the Environmental Laws and, to the best of
ONB's knowledge, 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 business by any of ONB's subsidiaries or the
consummation of the Merger.  To the best of ONB's knowledge, ONB is not 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 some other remedial action
under any of the Environmental Laws.

          5.13.  Representations and Warranties at the Effective Date.  All
representations and warranties of ONB and First Citizens contained herein shall

Effective Time as though made or given at such time.

          5.14.  Nonsurvival of Representations and Warranties.  The
representations and warranties of ONB and First Citizens contained in this

Citizens and all directors, officers and employees of ONB and First Citizens
shall have no further liability with respect thereto.  Nothing in the foregoing
shall result in the termination of any covenants provided for herein that shall
survive by their terms the Effective Time.

          6.05.  Restrictions Regarding Affiliates.  Savings Bank shall, within
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 Savings Bank for purposes of Rule

director, executive officer and other person who may be deemed to be such an
affiliate of Savings Bank to deliver to ONB on or prior to the Effective Time
hereunder a written agreement, substantially in the form as attached hereto as
Exhibit A, providing that such person (a) has not sold, pledged, transferred,

under the 1933 Act or pursuant to Rule 145 under the 1933 Act or another
exemption from 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), Savings Bank shall not, nor shall it permit or authorize its
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 Savings Bank or to which Savings Bank may become a party (all such
transactions are hereinafter referred to as "Acquisition Transactions").
Savings Bank shall promptly communicate to ONB the terms of any proposal or
offer which it 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 herein provided, Savings Bank may
engage, and may permit and authorize its directors, officers, employees, agents
or representatives to 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 Savings Bank promptly upon receipt by ONB of a
letter from Savings Bank signed by at least a majority of its Board of Directors
then in office indicating that Savings Bank has received an unsolicited offer
regarding an Acquisition Transaction which the Board of Directors of Savings
Bank (i) considers, in the exercise of its fiduciary duties as a Board, to be
superior (in more than an insubstantial manner and taking into account all
relevant factors) 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
Savings Bank when and if ONB shall, in its sole discretion, determine.  This
Section 6.06 shall not authorize Savings Bank or any of 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, Savings Bank 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.  Savings Bank 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 Savings
Bank 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 Savings Bank.  ONB and
its respective

                                      A-26

<PAGE>
 
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 Savings Bank and of its 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
Savings Bank; and provided further, that if ONB elects to conduct or have
conducted on its behalf an environmental review, study, survey or assessment to
verify the representations and warranties given by Savings Bank with respect to
the environmental matters specified in Section 4.11(b) hereof, such
environmental review, study, survey or assessment shall be completed and all
reports and findings related thereto shall be disclosed to Savings Bank within
forty-five (45) days of the date thereof.  Upon request, Savings Bank shall
furnish ONB or its representatives or agents, its attorneys' responses to
external auditors requests for information, management letters received from its
external auditors and such financial, loan and operating data and other
information reasonably requested by ONB which has been or is developed by
Savings Bank or its auditors, accountants or attorneys (provided with respect to
attorneys, such disclosure would not result in the waiver by Savings Bank 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 Savings Bank,
and such auditors and accountants shall be directed to furnish copies of any
reports or financial information as developed to ONB or its auditors or
accountants.  No investigation by ONB shall affect the representations and
warranties made by Savings Bank 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 Savings Bank's request, returned to Savings Bank in the event this
Agreement is terminated as provided in Section 9 hereof. This Section 6.09 shall
not require the disclosure of any information to ONB which would be prohibited
by law.

          6.10.  Subsequent Savings Bank Financial Statements.  As soon as
available after the date of this Agreement, Savings Bank shall deliver to ONB
the monthly unaudited consolidated balance sheets and profit and loss statements
of Savings Bank prepared for its internal use, Savings Bank's Forms 10-Q 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 Savings
Bank Financial Statements").  The Subsequent Savings Bank Financial Statements
shall be prepared on a basis consistent with past accounting practices and
generally accepted accounting principles applied on a consistent basis and shall
present fairly the financial condition and results of operations as of the dates
and for the periods presented.  The Subsequent Savings Bank Financial Statements
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 material respect.

          6.11.  Employee Benefits.  The provision of any employee benefits by
ONB or any of its subsidiaries to employees of Savings Bank shall not (i) create
any employment contract, agreement or understanding with any of the officers or
employees of Savings Bank or (ii) except as expressly provided in this
Agreement, 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; provided that any such change,
amendment or termination applies to a broad class of similarly situated
employees and not only to former employees of Savings Bank.

          6.12.  Supplemental Benefit Agreements.  Savings Bank shall not enter
into any Director Supplemental Benefit Plan Agreements or Employee Supplemental
Benefit Plan Agreements in addition to

                                      A-27

<PAGE>
 
those set forth in the Disclosure Schedule.  Savings Bank shall amend or modify
such agreements only as required by Section 7.03 hereof.

          6.13.  Shorewalk Development.  Notwithstanding anything in this
Agreement to the contrary, Savings Bank shall not enter into any agreement,
understanding or arrangement relating to the sale or the transfer of any
interest in the Shorewalk at Geist development without the prior written consent
of ONB, which consent will not be unreasonably withheld.

          6.14.  Restructure.  Savings Bank hereby understands, acknowledges and
agrees that ONB, in its sole discretion, may change the structure of the Merger.
Such change of structure may include, without limitation, acquiring Savings Bank
as a wholly-owned subsidiary and having its principal office in Bloomington,
Indiana.  Savings Bank covenants and agrees to execute and deliver such
amendments, agreements and instruments and take such further actions as ONB may
reasonably request in connection with such restructure; provided, that any such
restructure shall not change the Exchange Ratio or tax-free nature of the
transactions contemplated by this Agreement and that the covenants of ONB set
forth in Section 7 hereof will be honored and assumed by any new resulting
entity to the extent not honored or assumed by ONB.

          6.15.  Employment Agreement.  Prior to the Effective Time, Savings
Bank shall cause the employment agreement dated March 18, 1986 between Savings
Bank and Mr. William M. Marley to be amended such that his position with Savings
Bank will be Vice Chairman, that the requirement that he participate in a stock
option plan or supplemental benefit plan (other than as required herein) shall
be deleted and that he will receive employee benefits in accordance with ONB's
employee benefit plans.

          6.16.  Certain Actions.  Savings Bank shall not intentionally or
knowingly take, cause to be taken or fail to take any action which will cause or
result in a misrepresentation or a breach of a covenant or warranty of this

                                COVENANTS OF ONB
                                ----------------

          ONB covenants and agrees with Savings Bank as follows:

          7.01.  Approvals.  (a) ONB shall have primary responsibility for the
preparation, filing and cost of all holding company, bank and savings
association regulatory applications required for consummation of the Merger.
ONB shall file all such applications as soon as practicable after the execution
of this Agreement. ONB shall provide to Savings Bank's counsel copies of all
material written communications with all state and federal bank regulatory
agencies relating to such applications.  ONB shall proceed expeditiously,
cooperate fully and use its best efforts to procure, upon terms and conditions
reasonably acceptable to ONB, all consents, authorizations and approvals to
complete all filings and applications and to satisfy all other requirements
prescribed by law which are necessary for consummation of the Merger on the
terms and conditions provided in this Agreement at the earliest possible
reasonable date.

          (b) So long as this Agreement is submitted to Savings Bank's
shareholders for a vote thereon, Interim Thrift shall submit this Agreement to
ONB, as its sole shareholder, for approval by unanimous written consent without
a meeting in accordance with applicable law and the Charter and By-Laws of
Interim Thrift,

                                      A-28
<PAGE>
 
and the Board of Directors of Interim Thrift shall recommend to its sole
shareholder that such shareholder approve this Agreement and the Merger.

          (c) So long as the actions contemplated by Section 7.01(b) hereof have
occurred, ONB shall vote all of its shares of capital stock of Interim Thrift in
favor of approval of this Agreement.

          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 Savings Bank, prepared for use in
connection with the meeting of shareholders of Savings Bank referred to in
Section 6.01 hereof, all in accordance with the rules and regulations of the
SEC.  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 issuance of ONB common stock.  In advance of
filing the Registration Statement and all other filings described in Section
7.01 hereof, ONB shall provide Savings Bank and its counsel with a copy of the
Registration Statement and each such other filing and provide an opportunity for
them to comment thereon prior to filing.

          7.03.  Employee and Director Benefit Plans.  (a) General.  ONB will
make available to the employees of Savings Bank who continue as employees of any
subsidiary of ONB after the Effective Time substantially the same employee
benefits on substantially the same terms and conditions that ONB may offer to
similarly situated employees of its banking subsidiaries from time to time.

          (b) Eligibility and Vesting.  Years of service of an employee of
Savings Bank prior to the Effective Time shall be credited to each such employee
eligible for coverage under Section 7.03(a) hereof for purposes of eligibility
under ONB's employee welfare benefit plans and for purposes of eligibility and
vesting, but not for purposes of benefit accrual or contributions, under the ONB
Pension Plan and the ONB Employees' Savings and Profit Sharing Plan ("ONB Profit
Sharing Plan").  Those employees of Savings Bank who otherwise meet the
eligibility requirements of the ONB Profit Sharing Plan, based upon their age
and years of service for Savings Bank, shall become participants thereunder on
the January 1st which coincides with or next follows the effective date of the
termination of the ESOP as described in Section 7.03(f) hereof. Those employees
of Savings Bank who otherwise meet the eligibility requirements of the ONB
Pension Plan, based upon their age and years of service for Savings Bank, shall
become participants thereunder on the January 1st which coincides with or next
follows the effective date of the termination of the Savings Bank Retirement
Plan as described in Section 7.03(c) hereof.  Those employees who do not meet
the eligibility requirements of the ONB Pension Plan or the ONB Profit Sharing
Plan on such dates 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) Financial Institutions Retirement Fund.  The Savings Bank
Retirement Plan will be terminated and frozen effective December 31, 1995, and
all accrued benefits of participants in the Savings Bank Retirement Plan shall
thereupon become fully vested.  Each participant in the Savings Bank Retirement
Plan shall leave his or her accrued benefits in the Savings Bank Retirement Plan
and have them payable at the times and in the amounts provided for under that
plan.  ONB shall be responsible for the termination of the Savings Bank
Retirement Plan and for making application to the Service for a determination
letter to the

                                      A-29

<PAGE>
 
effect that the termination of the Savings Bank Retirement Plan does not
adversely affect its tax-qualified status.  Savings Bank shall make
contributions to the Savings Bank Retirement Plan for the period from the
Effective Time through December 31, 1995 only to the extent required to maintain
the plan's tax-qualified status and avoid any federal income taxes or penalties.

          (d) Director Supplemental Benefit Plan Agreements.  ONB shall continue
to make, or shall cause one or more of its subsidiaries to make, the payments
due under each of the Director Supplemental Benefit Plan Agreements which were
in pay status immediately prior to the Effective Time (because the director
ceased to be a director or attained "Retirement Age", as defined in such
agreements, prior to the Effective Time) in accordance with the terms thereof.

          Prior to the Effective Time, Savings Bank shall amend each Director
Supplemental Benefit Plan Agreement for each director of Savings Bank as of the
Effective Time who is not currently in pay status to (i) increase the monthly
allocation due under Section 2 of the agreement from $350 to $700 to be
effective as of the Effective Time, (ii) provide for the cessation of benefit
accruals under each agreement effective as of the end of the month which
coincides with or next follows the end of the three (3) year period beginning at
the Effective Time, in addition to provisions for benefit accrual cessation
currently in the agreements, (iii) eliminate the minimum monthly benefit
provisions, and (iv) provide for a lump sum cash payment of the director's
account balance under the agreement payable within ten (10) business days
following the earliest of the benefit cessation date or the date the director
ceases to be a director of an affiliate of ONB or the date the director attains
age 65.  Prior to the Effective Time, Savings Bank shall enter into a Director
Supplemental Benefit Plan Agreement with Alan G. Stanley to (i) provide for a
monthly allocation in the amount of $350 to be effective as of the Effective
Time, such monthly allocations to be made for a period ending as of the end of
the month which coincides with or next follows the end of the three (3) year
period beginning at the Effective Time, (ii) provide for the cessation of
benefit accruals under such agreement effective as of the end of the month which
coincides with or next follows the end of the three (3) year period beginning at
the Effective Time, and (iii) provides for a lump sum cash payment of the
account balance under the agreement payable within ten (10) business days
following the earliest of the benefit cessation date or the date the director
ceases to be a director of an affiliate at ONB.  ONB hereby agrees not to reduce
the monthly allocation under the Director Supplemental Benefit Plan Agreements
for the three (3) year period beginning as of the Effective Time.  During such
three-year period, ONB agrees not to make any other modifications to any such
agreements (whether or not in pay status) without first receiving the written
consent of the affected individual, unless otherwise required by law.

          (e) Employee Supplemental Benefit Plan Agreements.  Upon the
consummation of the Merger, ONB shall cause the Employee Supplemental Benefit
Plan Agreements entered into by Savings Bank and each of Rose Ada Wood, Donna L.
Bouslog and William M. Marley, as amended, to be terminated; provided, however,
that within ten (10) business days of the termination of such agreements, ONB
shall make a lump sum cash payment to each such employee equal to the amount
accrued on the books and records of Savings Bank for the benefit of such
employee at the Effective Time.  Prior to the Effective Time, Savings Bank shall
amend each of such Employee Supplemental Benefit Plan Agreements to provide for
the cessation of benefit accruals under the agreements as of the Effective Time
and for the payment of benefits to be made in a lump sum in the event the
agreement is terminated.

          (f) ESOP.  The ESOP shall be terminated effective December 31, 1995.
Savings Bank shall make contributions to the ESOP for the plan year beginning
January 1, 1994 and ending December 31, 1994 and the plan year beginning January
1, 1995 and ending December 31, 1995 in accordance with the terms of the ESOP
and not exceeding Two Thousand Dollars ($2,000) per month.  Effective as of the
Effective Time, all participants with an account balance under the ESOP shall
become fully vested in such accounts regardless

                                      A-30

<PAGE>
 
of their vested position under the ESOP.  Participants' benefits under the ESOP
shall be distributed, in connection with the ESOP termination, in a single lump
sum or by direct rollover to the ONB Profit Sharing Plan or an individual
retirement account.  Savings Bank shall eliminate in connection with the
termination of the ESOP the optional form of distribution in installments.  Such
distributions (or the cash proceeds thereof) shall be eligible to be rolled over
directly to the rollover account under the ONB Profit Sharing Plan; provided,
however, that if any participant in the ESOP directly rolls over any ONB common
stock into the ONB Profit Sharing Plan, such stock will be valued, for purposes
of establishing the participant's rollover account value, at the per share
closing price of ONB common stock as quoted on the NASDAQ National Market System
on the date of such stock's rollover into the ONB Profit Sharing Plan and such
stock will be commingled with other assets in the ONB Profit Sharing Plan with
no separate accounting maintained for such stock with respect to any
participant.  Upon a direct rollover of any ONB common stock into the ONB Profit
Sharing Plan, any participant who effects such a rollover will thereafter be
entitled only to an undivided interest in the assets of the ONB Profit Sharing
Plan and will not be entitled to maintain the rollover proceeds as a segregated
portion of the ONB Profit Sharing Plan assets.  ONB shall be responsible for the
termination of the ESOP and for making application to the Service for a
determination letter to the effect that the termination of the ESOP does not
adversely affect its tax-qualified status.

          (g) Certain Employee.  ONB agrees to cause First Citizens or Surviving
Thrift to assume Savings Bank's obligations (i) to pay health insurance premiums
under Savings Bank's health insurance plan (or another comparable plan) for Mr.
Jim Ross, a former employee of the Savings Bank, until he attains age 62 on
September 8, 1995, (ii) to pay him $586.85 per month until his death (with
payments guaranteed for not less than a ten year period beginning January 1,
1991) as a supplement to his retirement benefit under the Savings Bank
Retirement Plan to a level which he would have received had he retired effective
December 31, 1995, and (iii) to pay him $1,041.67 per month until December 31,
2000.  This covenant is made on the condition that the foregoing obligations
have been fully accrued for on the books and records of Savings Bank, subject
only to an interest expense with respect to such accrual of $300 per month.

          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 Savings Bank with respect to the Merger without the prior
consent of Savings Bank, which consent shall not be unreasonably withheld.

          7.06.  Information, Access Thereto, Confidentiality.  Savings Bank 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 facilities,
operations, books, records and properties of ONB.  Savings Bank and its
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 ONB and of its financial and legal condition as Savings Bank 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.  Upon request, ONB will furnish to Savings Bank or its representatives or
agents, such financial and operating data and other information reasonably
requested by Savings Bank which has been or is developed by ONB or its auditors,
accountants or attorneys (provided with respect to attorneys, such disclosure
would not result in the waiver by ONB of any claim of attorney-client
privilege), and will permit Savings Bank and its representatives or agents to
discuss such information directly with any individual or firm performing
auditing or accounting functions for ONB so long as a representative

                                      A-31

<PAGE>
 
or agent of ONB participates in such discussions.  No investigation by Savings
Bank shall affect the representations and warranties made by ONB.  Any
confidential information or trade secrets received by Savings Bank 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 containing such confidential
information or trade secrets or both shall be destroyed by Savings Bank 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 Savings Bank which would be prohibited by law.

          7.07.  Employment Agreement.  Following the Effective Time, ONB agrees
to honor and abide by the terms of the written employment agreement, in the form
which has been included in the Disclosure Schedule, dated March 18, 1986 between
Savings Bank and William M. Marley, the President of Savings Bank, as amended
pursuant to Section 6.15 hereof, except as may be otherwise required by any
government regulatory agency.  Such employment agreement shall be extended for
one (1) additional year in October 1994, consistent with Savings Bank's past
practices, upon the existing terms and conditions.

          7.08.  Directors.  For a period of not less than three (3) years
following the Effective Time, ONB agrees to elect as directors of First
Citizens or Surviving Thrift those persons who are serving as directors of
Savings Bank as of the Effective Time in accordance with Section 1.02 hereof.

          7.09.  Compliance with Antitrust and Other Laws.  Each of ONB, First
Citizens and Savings Bank shall use its best efforts to resolve such objections,
if any, which may be asserted with respect to the transactions contemplated by
the Purchase and Assumption Agreement ("P & A Transaction") and the Merger by
the Board of Governors of the Federal Reserve System ("Federal Reserve"), the
Department of Justice, the FDIC, the OTS or any other federal or state
governmental agency or body (collectively, the "Governmental Entities"),
including, without limitation, objections under any antitrust or banking laws.
Each of ONB and First Citizens shall use its best efforts to take such actions
as may be reasonably required by any such Governmental Entities in order to
resolve any such objections.  Best efforts shall include, but not be limited to,
the proffer of ONB and/or First Citizens of its willingness to accept an order
agreeing to the divestiture, or the holding separate, of any assets or deposits
of First Citizens unless the acceptance of any such order is determined by the
Board of Directors of ONB after consultation with the Board of Directors of
Savings Bank and their respective legal and financial advisors to so materially
and adversely impact the anticipated financial condition or results of
operations of the Surviving Thrift or First Citizens  (on a consolidated basis
with ONB) after the Effective Time as to render the consummation of the P&A
Transaction or the Merger unacceptable to ONB or otherwise imprudent.  If ONB or
First Citizens shall determine that it is necessary or advisable in order to
resolve or minimize objections that may be asserted with respect to the P&A
Transaction or the Merger by a Governmental Entity or otherwise, that ONB or
First Citizens shall not acquire (directly or indirectly) from Savings Bank
certain assets or deposit liabilities of Savings Bank, then ONB or First
Citizens shall so notify Savings Bank and shall identify those assets and
deposit liabilities, if any, which ONB or First Citizens proposes that it should
not acquire, and Savings Bank shall take appropriate steps to divest such assets
or deposit liabilities, provided that the obligation of Savings Bank to
consummate any such divestiture shall be subject to the condition that the P&A
Transaction and the Merger be simultaneously consummated.  In the event a suit
is threatened or instituted challenging the P&A Transaction or the Merger as
violative of the antitrust laws, ONB, First Citizens and Savings Bank shall use
their best efforts to avoid the filing of, resist or resolve any such suit.
Notwithstanding any such threatened or actual lawsuit, this Section shall not in
any way affect or limit any party's right to terminate this Agreement pursuant
to Section 9.01(a) hereof.  Notwithstanding anything contained in this
Agreement, the representations and warranties of ONB or Savings Bank in this
Agreement shall not be deemed to be untrue or breached, ONB or Savings Bank
shall not be deemed to have failed to perform any covenant or obligation
contained in this

                                      A-32
<PAGE>
 
Agreement, and no condition to ONB's or Savings Bank's obligation to effect the
P&A Transaction or the Merger shall be deemed not to have been satisfied, by or
as a result of any divestitures or other acts consummated pursuant to this
Section 7.09.

          7.10.  Indemnification and Insurance.  (a) Indemnification.  From and
after the Effective Time, ONB will cause the Surviving Thrift (with respect to
those directors and officers of Savings Bank who become directors or officers of
the Surviving Thrift immediately following the Effective Time) and First
Citizens (with respect to those directors and officers of Savings Bank who
become directors or officers of First Citizens immediately following the
Effective Time) to assume and honor any obligations as provided for and
permitted by applicable federal and state law which Savings Bank 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 Savings Bank
or any of the Subsidiaries or was serving at the request of Savings Bank 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 Savings Bank's Charter 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 Savings Bank or any of the Subsidiaries.  Indemnification of employees and
directors of Savings Bank and the Subsidiaries 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
Savings Bank (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 Savings Bank 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 officers of ONB and its
bank subsidiaries.

          7.11.  Tax-Free Reorganization.  ONB and First Citizens shall take no
actions following the Effective Time which would cause the Merger to lose its
status as a reorganization described in (S) 368(a)(2)(E) of the Code.  To that
end, First Citizens will continue at least one historic business line of Savings
Bank, or use at least a significant portion of Savings Bank's historic business
assets in a business, in each case within the meaning of Treas. Reg. 
(S) 1.368-1(d).

          7.12   Board Approval.  ONB shall present this Agreement to its Board
of Directors for approval at  the Board's October, 1994 meeting.

                             TERMINATION OF MERGER
                             ---------------------

          9.01.  Manner of Termination.  This Agreement and the Merger may be
terminated at any time prior to the Effective Time by written notice delivered
by ONB to Savings Bank, or by Savings Bank to ONB, as follows:

          (a)  By ONB or Savings Bank, if:

               (i)    the Merger contemplated by this Agreement has not been 
                      consummated by January 31, 1996; or

               (ii)   the respective Boards of Directors of ONB and Savings 
                      Bank mutually agree to terminate this Agreement.

          (b)  By ONB, if:

               (i)    ONB's independent auditors determine that the Merger will 
                      not qualify for pooling-of-interest accounting treatment 
                      for ONB; or

               (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, prospects, assets, capitalization, financial
                      condition or results of operations of Savings Bank; or

               (iii)  there has been a misrepresentation or a breach of any 
                      warranty by or on the part of Savings Bank in its
                      representations and warranties set forth in this Agreement
                      which has had or would be expected to have, in the
                      reasonable discretion of ONB, a material adverse effect on
                      the business, prospects, assets, capitalization, financial
                      condition or results of operations of Savings Bank;
                      provided, however, that in the event of any inaccuracy in
                      the representations and warranties contained in Section

                                      A-36
<PAGE>
 
                      4.03 hereof relative to the number of issued and
                      outstanding shares of Savings Bank or the Subsidiaries,
                      ONB shall have the absolute right to terminate this
                      Agreement without regard to the materiality of any such
                      inaccuracy; or

               (iv)   there has been a breach of or failure to comply with any 
                      covenant set forth in this Agreement by or on the part of 
                      Savings Bank; or

               (v)    it shall reasonably determine that the P&A Transaction or 
                      the Merger has become inadvisable or impracticable by
                      reason of commencement or threat of any claim, litigation
                      or proceeding (except as contemplated by Section 7.09
                      hereof) against ONB, First Citizens, Savings Bank, any of
                      the Subsidiaries or any subsidiary of ONB, or any director
                      or officer of any of such entities (A) relating to this
                      Agreement, the P&A Transaction or the Merger or (B) which
                      is likely to have a material adverse effect on the
                      business, prospects, assets, capitalization, financial
                      condition or results of operations of Savings Bank or of
                      ONB on a consolidated basis; or

               (vi)   except as provided in the Disclosure Schedule, there has 
                      been a material adverse change in the business, prospects,
                      assets, capitalization, financial condition or results of
                      operations of Savings Bank as of the Effective Time as
                      compared to that in existence as of June 30, 1994; or

               (vii)  (A) subject to ONB's obligations in Section 7.09 hereof, 
                      ONB reasonably determines that any term or condition
                      imposed upon or proposed to ONB, First Citizens or the
                      Surviving Thrift by a Governmental Entity relative to the
                      federal antitrust laws with respect to the P&A Transaction
                      or the Merger would so materially and adversely impact the
                      anticipated financial condition or results of operations
                      of the Surviving Thrift or First Citizens (on a
                      consolidated basis with ONB) after the Effective Time as
                      to render the consummation of the P&A Transaction or the
                      Merger unacceptable to ONB or otherwise imprudent, or (B)
                      the P&A Transaction or the Merger is not able to be
                      consummated because a Governmental Entity denies approval
                      of the Merger on antitrust grounds or a lawsuit is filed
                      to enjoin the P&A Transaction or the Merger on antitrust
                      grounds (and such denial or legal action is not subject to
                      further administrative or judicial appeal).

          (c)  By Savings Bank, if:

               (i)    there has been a misrepresentation or a breach of any 
                      warranty 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 Savings Bank, a material adverse effect on the
                      business, assets, capitalization, financial condition or
                      results of operation of ONB on a consolidated basis; or

               (ii)   there has been a breach of or failure to comply with any 
                      covenant set forth in this Agreement by or on the part of 
                      ONB; or

               (iii)  there has been a material adverse change in the financial
                      condition, results of operations, business, assets or
                      capitalization of ONB on a consolidated basis as of the
                      Effective Time as compared to that in existence on June
                      30, 1994.

shareholders, except as provided in compliance with the confidentiality

          12.09.  Expenses.  ONB and Savings Bank shall each pay their
respective expenses incidental to the Merger.  Notwithstanding the foregoing, if

antitrust grounds or a lawsuit is filed to enjoin the Merger or the P&A
Transaction on antitrust grounds (and such denial or legal action is not subject
to further administrative or judicial appeal), and ONB thereafter terminates
this Agreement pursuant to Section 9.01(b)(vii) hereof, ONB will, within ten
(10) days after such termination of the Merger, reimburse Savings Bank for all
reasonable out-of-pocket expenses and fees incurred by it or on its behalf in

of business.

                               __________, 1995



Board of Directors
First United Savings Bank, f.s.b.
One Locust Street
Greencastle, IN 46135

Gentlemen:

     You have requested our opinion with respect to the fairness, from a
financial point of view, as of the date hereof, to the holders of common stock,
par value $0.01 per share ("FUSB Common Stock"), of First United Savings Bank,
f.s.b. ("FUSB") of  the exchange ratio as set forth in Section 2.01 of the
Amended and Restated Agreement of Affiliation and Merger, effective September
29, 1994 (the "Agreement"), by and among FUSB, Old National Bancorp ("ONB")
First Citizens Bank & Trust Company, a wholly owned subsidiary of ONB and ONB
Interim Federal Savings Bank, whereby issued and outstanding shares of FUSB
Common Stock would be exchanged for a specified number of shares of common
stock, no par value ("ONB Common Stock"), of ONB.

     The Agreement and its related Purchase and Assumption Agreement (the "P&A
Agreement") provide for, among other things, the merger (the "Merger") of FUSB
with and into a newly formed savings bank subsidiary of ONB, accomplished
through certain sequential transactions which are more fully described in the
Agreement and the P&A Agreement, occurring immediately prior to the Effective
Date (as defined in the Agreement).  Pursuant to the Merger, outstanding shares
of FUSB Common Stock will exchanged for 0.8925 shares of ONB Common Stock, as
set forth in Section 2.01 of the Agreement (the "Exchange Ratio"), subject to
adjustment, if any as set forth in Sections 2.01 (b) and 2.03 of the Agreement.
The terms and conditions of the Merger are more fully set forth in the
Agreement.

     McDonald & Company Securities, Inc., as part of its investment banking
business, is customarily engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes.

     We have acted as FUSB's financial advisor in connection with, and have
participated in certain negotiations leading to, the execution of the Agreement.
In connection with rendering our opinion set forth herein, we have among other
things:

     (i)    Reviewed FUSB's Annual Reports to Shareholders and Annual Reports on
            Form 10-K for each of the three years in the three year period ended
            June 30, 1994, including the audited financial statements contained
            therein, as well as FUSB's Quarterly Reports on Form 10-Q for each
            of the three month periods ended September 30, 1994, December 31,

     (ii)   Reviewed ONB's Annual Reports to Shareholders and Annual Reports on
            Form 10-K for each of the three years in the three year period ended
            December 31, 1994, including the audited financial statements
            contained therein, as well as ONB's Quarterly Reports on Form 10-Q
            for each of the three month periods ended March 31, 1995, and June
            30, 1995;

     (iii)  Reviewed certain other public and non-public information, primarily 
            financial in nature, relating to the respective businesses,
            earnings, assets and prospects of FUSB and ONB provided to us or
            publicly available;

     (iv)   Participated in meetings with members of senior management of FUSB 
            and telephone conferences with members of senior management of ONB
            concerning the financial condition, business, assets, financial
            forecasts and prospects of the respective companies, as well as
            other matters we believe relevant to our inquiry;

     (v)    Reviewed certain stock market information for FUSB Common Stock and 
            ONB Common Stock, and compared it with similar information for
            certain companies, the securities of which are publicly traded;

     (vi)   Compared the results of operations and financial condition of FUSB 
            and ONB with that of certain companies which we deemed to be
            relevant for purposes of this opinion;

     (vii)  Reviewed the financial terms, to the extent publicly available, of 
            certain acquisition transactions which we deemed to be relevant for
            purposes of this opinion;

     (viii) Reviewed the Agreement and its schedules and exhibits and certain
            related documents; and

     (ix)   Performed such other analyses as we have deemed appropriate.

     In our review and analysis and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and other
information reviewed by us and have relied upon the accuracy and completeness of
the representations and warranties of FUSB and ONB contained in the Agreement.
We have not been engaged to undertake, and have not conducted, an independent
investigation or verification of such matters.  We have not been engaged to and
we did not conduct a physical inspection of any of the assets, properties or
facilities of either FUSB or ONB, nor have we made or obtained or been furnished
with any independent evaluation or appraisal of any of such assets, properties
or facilities or any of the liabilities of either FUSB or ONB.  With respect to
financial forecasts used in our analysis, we have assumed that such forecasts
have been reasonably prepared on a basis reflecting the best currently available
estimates and judgments of the management of FUSB and ONB as to the future
performance of FUSB and ONB, as the case may be.  We express no view as to such
financial forecasts or the assumptions on which they are based. We have also
assumed that all of the conditions to the consummation of the Merger, as set
forth in the Agreement,  would be satisfied and that the Merger would be
consummated on a timely basis in the manner contemplated by the Agreement.

     We will receive a fee for our services as financial advisors to FUSB, a
portion of which is contingent upon closing of the Merger.

     In the ordinary course of business, we may actively trade securities of
FUSB and ONB for our own account and for the accounts of customers and,
accordingly, we may at any  time hold a long or short position in such
securities.

     This opinion is based on economic and market conditions and other
circumstances existing on, and information made available as of, the date
hereof.  In addition, our opinion is, in any event, limited to the fairness, as
of the date hereof, from a financial point of view, of the Exchange Ratio to the
holders of FUSB Common Stock and does not address FUSB's underlying business
decision to effect the Merger or any other terms of the Merger and does not
constitute a recommendation to any FUSB shareholder as to how such shareholder
should vote with respect to the Merger.  This opinion does not represent our
opinion as to what the value of FUSB Common Stock or ONB Common Stock may be at
the Effective Date of the Merger or as to the prospects of ONB's business.

     This opinion has been prepared solely for the confidential use of the Board
of Directors and senior management of FUSB and will not be reproduced,
summarized, described or referred to or given to any other person without our
prior written consent.  Notwithstanding the foregoing, this opinion may be
included in a proxy statement to be mailed to the holders of FUSB Common Stock
and ONB Common Stock in connection with the Merger, provided that this opinion
will be reproduced in such proxy statement in full, and any description of or
reference to us or our actions, or any summary of the opinion in such proxy
statement will be in a form acceptable to us and our counsel.

     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Exchange Ratio, pursuant to the Agreement, is fair to the
holders of FUSB Common from a financial point of view.

                              Very truly yours,

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     The Registrant's Articles of Incorporation provide that the Registrant will
indemnify any person who is or was a director, officer or employee of the
Registrant or of any other corporation for which he is or was serving in any
capacity at the request of the Registrant against all liability and expense that
may be incurred in connection with any claim, action, suit or proceeding with
respect to which such director, officer or employee is wholly successful or
acted in good faith in a manner he reasonably believed to be in, or not opposed
to, the best interests of the Registrant or such other corporation and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
that his conduct was unlawful.  A director, officer or employee of the
Registrant is entitled to be indemnified as a matter of right with respect to
those claims, actions, suits or proceedings where he has been wholly successful.
In all other cases, such director, officer or employee will be indemnified only
if the Board of Directors of the Registrant or independent legal counsel finds
that he has met the standards of conduct set forth above.

ITEM 22.  UNDERTAKINGS.

  (a) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

  (b)  (1)  The undersigned registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through the use
of a prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.

       (2) The undersigned registrant hereby undertakes that every prospectus
(i) that is filed pursuant to paragraph (b)(1) immediately preceding or (ii)
that purports to meet the requirements of Section 10(a)(3) of the Act, and is
used in connection with an offering of securities subject to Rule 415, will be
filed as a part
                                      II-2
<PAGE>
 
of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

  (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer, or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

  (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means.  This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

  (e) The undersigned registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.

     RE:  Issuance of Shares of Common Stock of Old National Bancorp in
          connection with the Affiliation with First United Savings Bank, f.s.b.

Ladies and Gentlemen:

  We have represented Old National Bancorp ("ONB") as special counsel in
connection with the preparation and filing of a Registration Statement on Form
S-4 (the "Registration Statement") with the Securities and Exchange Commission
for the purpose of registering shares of ONB's no par value common stock under
the Securities Act of 1933, as amended (the "Shares").  The Shares are proposed 
to be issued to shareholders of First United Savings Bank, f.s.b. ("FUSB"),
Greencastle, Indiana, in connection with the affiliation of FUSB with ONB
("Affiliation"), as specified in the Amended and Restated Agreement of
Affiliation and Merger, dated as of September 29, 1994 (the "Agreement"), by and
among ONB, FUSB, First Citizens Bank and Trust Company and ONB Interim Federal
Savings Bank.  The Affiliation will be accomplished and the Shares will be 
issued pursuant to the specific terms of the Agreement.  In connection with this
opinion, we have reviewed and are familiar with ONB's Articles of Incorporation
and By-Laws and such other records, documents and information as we have in our
judgment deemed relevant.

  Based upon the foregoing, it is our opinion that if and when the Affiliation
is consummated, the Shares will, when issued to shareholders of FUSB in
accordance with all of the terms and conditions of the Agreement, be legally
issued, fully paid and non-assessable.  This opinion is limited to the matters
stated herein, and no opinion is to be implied or may be inferred beyond the
matters expressly stated.

  This opinion is addressed to you and is solely for your use in connection with
the Registration Statement, and we assume no professional responsibility to any
other person whatsoever.  Accordingly, the opinion expressed herein is not to be
relied upon, utilized or quoted by or delivered or disclosed to, in whole or in
part, any other person, corporation, entity or governmental authority without,
in each instance, the prior written consent of this firm.

  We hereby consent to the use of this opinion as an exhibit to the Registration
Statement and to the reference made to us in the Registration Statement and the
Prospectus forming a part thereof under the caption "Legal Opinions".  In giving
this consent, we do not thereby admit that we come within the category of

                           First United Savings Bank

                      Management Discussion and Analysis


GENERAL

The principal business of First United Savings Bank, f.s.b. ("First United" or
the "Bank") has always been to accept deposits from the general public and
invest those deposits, together with funds from earnings and borrowings,
primarily in first mortgage loans secured by one-to-four family residential
properties and, to a lesser extent, in multi-family residential and consumer
loans.  In the fiscal year ended June 30, 1995, specific steps were taken to
ensure that business will be carried out in the best interests of the Bank's
customers and shareholders.

Effective September 29, 1994, First United entered into an Agreement of
Affiliation and Merger (as amended and restated, the "Agreement") with Old
National Bancorp ("Old National"), pursuant to which a federally chartered
interim savings bank and wholly-owned subsidiary of Old National will be merged
with and into First United (the "Merger").  Immediately prior to the Merger, the
assets and liabilities associated with First United's Greencastle and Danville,
Indiana operations, and shares of its insurance subsidiary, will be transferred
to a commercial bank subsidiary of Old National.  Following the Merger, First
United's Bloomington operation will operate as a wholly-owned thrift subsidiary
of Old National and its Greencastle and Danville operations will be conducted as
part of First Citizens Bank and Trust Company.  In connection with the Merger,
each issued and outstanding share of First United common stock will be converted
into the right to receive .8925 shares of Old National common stock, subject to
adjustments more particularly described in the Agreement.  It is expected that
the Merger will be consummated by the end of 1995.

In the second quarter of fiscal 1995, First United recorded merger charges of
approximately $1,286,000 on a pre-tax basis.  These charges included an
additional $500,000 loan loss provision to conform to Old National's loan loss
provisioning policies, a $321,000 liability for professional fees relating to
the pending merger, a reduction in a lease intangible asset value by $131,000, a
liability of $105,000 for anticipated costs to terminate a data processing
contract, and an additional provision of $200,000 relating to the Bank's
investment in the Shorewalk at Geist condominium project.  These charges do not
violate any provision of the Agreement.

Since the Bank acquired Fountain Federal Savings Bank, Bloomington, Indiana, in
1988, a great deal of time and energy was devoted to the development and sale of
the Shorewalk condominium project in Indianapolis acquired in the merger.  At
the end of fiscal 1994, the Bank decided not to develop the final phase of the
Shorewalk project, reduced its basis in Shorewalk, and placed the land on the
market for sale in undeveloped form.  At June 30, 1995, the Bank sold Shorewalk
on contract to an independent third party for a purchase price of $900,000.  The
contract requires payment, in advance, on a lot by lot basis as the purchaser
commences development of each lot.  In connection with the sale, the Bank
recorded additional charges of $270,000 to reduce the Bank's basis to the sales
price.

As a result of the various charges described above, the Bank incurred a net loss
for fiscal 1995 of $650,000, or $1.15 per share, as compared to a net loss for
in the prior year of $1,000,000, or $1.84 per share.  Net interest income before
provision for loan losses and, therefore, before any merger related or Shorewalk
adjustments, was $3,679,000 compared to $3,272,000 in the prior year.

ASSET/LIABILITY MANAGEMENT

First United's exposure to interest rate risk is due to the differences in
maturities and volatility of rate-sensitive assets and rate-sensitive
liabilities.  The term "rate sensitivity" refers to those assets and liabilities
which are "sensitive" to fluctuations in rates and yields.  Savings institutions
have historically operated in a mismatched position with interest-sensitive
liabilities greatly exceeding interest-sensitive assets.  In periods of rising
interest rates, an institution in this position would almost certainly
experience lower earnings as interest-sensitive liabilities (deposits and other
borrowings) would reprice upward at a more rapid rate than interest-sensitive
assets (loans and investments).  First United has attempted to improve its
matching of rate-sensitive assets and rate-sensitive liabilities by promoting
adjustable rate mortgages, selling all currently originated fixed rate long term
mortgage loans and promoting certificates of deposit with maturities of three
years or longer.  The following table shows the Bank's projected interest
sensitivity gap based on loan repayment and deposit decay rates used by the
Federal Home Loan Bank of Indianapolis and based on information reported to the
Office of Thrift Supervision ("OTS") in the June 30, 1995 "Maturity and Rate
Schedule CMR".

</TABLE>

In evaluating First United's exposure to interest rate risk, certain
shortcomings inherent in the method of analysis presented in the foregoing table
must be considered.  For example, although certain assets and liabilities may
have similar maturities or periods to repricing, they may react in different
degrees to changes in market interest rates.  Additionally, the interest rates
on certain types of assets and liabilities may fluctuate in advance of changes
in market interest rates, while interest rates on other types may lag behind
changes in market rates.  Further, certain assets, such as adjustable rate
mortgages, have features which restrict changes in interest rates on a short-
term basis and over the life of the asset.  In addition, in the event of a
change in interest rates, prepayment and early withdrawal levels could deviate
significantly from those assumed in calculating the table.  Moreover, the
ability of many borrowers to service their debt may decrease in the event of an
interest rate increase.  First United considers the anticipated effects of these
various factors in implementing its interest rate risk management objectives.
Management believes that continuation of its efforts to manage the rates,
liquidity and interest rate sensitivity of First United's assets and liabilities
is necessary to generate an acceptable return.

INTEREST RATE SPREAD

First United's pre-tax earnings depend primarily on its net interest income, the
difference between the income it receives on its loan portfolio and other
investments and its cost of money consisting of interest paid on deposits and
borrowings.  When interest-earning assets approximate or exceed interest-bearing
liabilities, a positive interest rate spread will generate net interest income.
Thrift institutions have traditionally used interest rate spreads as a measure
of net interest income.  Another indication of an  institution's net interest
income is its "net yield on weighted average interest earnings assets", which is
net interest income divided by weighted average interest-earnings assets.

The following table sets forth the weighted average effective interest rate
earned by First United on its loan and investment portfolios, the weighted
average effective cost of First United's deposits and borrowings, the interest
rate spread of First United and the net yield on weighted average interest-
earning assets of First United on its loan portfolio and investments for the
periods and as of the dates shown.  Average balances are based substantially on
daily balances.

RATE/VOLUME ANALYSIS

The following table describes the extent to which changes in interest rates and
changes in volume of interest-related assets and liabilities have affected the
Bank's interest income and interest expense during the periods indicated.  For
each category of interest-earning asset and interest-bearing liability,
information is provided on changes attributable to (1) changes in rate (change
in rate multiplied by old volume), (2) changes in volume (change in volume
multiplied by old rate), and (3) changes in rate volume (change in rate
multiplied by the change in volume), which have been allocated to the change in
rate and the change in volume based upon their respective percentages of the
combined totals.  During 1994 and 1993, the Bank capitalized $35,500 and $51,000
of interest expense, respectively, on the construction of the Shorewalk at Geist
condominium project.  To facilitate comparability, the resulting decrease in
interest expense is not considered below.

YEAR ENDED JUNE 30, 1995 COMPARED TO YEAR ENDED JUNE 30, 1994

Net Interest Income
-------------------

Interest and fees on loans increased $988,000 from that in 1994.  The
fluctuation was caused by a rise in the weighted average loan portfolio yield of
 .42%, and by an increase in the average daily balance of loans outstanding of
$4,227,000.  Interest income on investments, mortgage-backed securities, and
other interest-bearing assets decreased $137,000 as a result of a .06% increase
in the weighted average yield offset by a decrease in the average daily balance
of $2,370,000.  Total interest expense of the Bank increased $444,000 for 1995.
The average daily balance of customer deposits in 1995 was $6,033,000 lower than
in the prior year and the weighted average rate paid on deposits increased .52%.
The results of the above fluctuations was an increase in net interest income of
$407,000 from the previous year.

                                      -4-
<PAGE>
 
Provision for Loan Losses
-------------------------

The 1995 provision for loan losses of $746,000 includes an additional $500,000
to conform to Old National's loan loss provising policies.  The Bank recorded
charge-offs (net of recoveries) in 1995 totaling $125,000.  In the prior year,
the provision for loan losses was $122,000 with net charge-offs of $45,000.

Other Income
------------

Total noninterest income of the Bank increased $16,000 to $616,000 for 1995.
During the current year, the Bank sold loans in the secondary market totaling
$3,194,000 and realized net gains of $12,000 as compared to net gains in the
prior year of $78,000.  The Bank actively manages a trading account portfolio
and realized net losses in 1995 of $36,000, as compared to $69,000 in the prior
year, on sales from the trading account as well as a mutual fund.

Other Expense
-------------

During the fourth quarter of 1994, the Bank decided not to develop the final
phase of the Shorewalk project and reduced its carrying value in the project by
$2,463,000 to its estimated fair value based on an independent appraisal.  In
the second quarter of fiscal 1995, the Bank recorded an additional charge of
$200,000 based on its internal review of the project.  In the fourth quarter of
fiscal 1995, the Bank charged an additional $270,000 to expense in connection
with the sale of the project, on a contract basis, to a local developer.
Excluding Shorewalk charges, the Bank's noninterest expense increased $1,330,000
from 1994 primarily from merger related expenses of $450,000 which are included
in miscellaneous expense in 1995.

The Bank changed from a single-employer pension plan to participation in a
multi-employer plan in 1994.  As a result of this change in plans, the Bank was
able to reduce its accrued pension liability to its estimated unfunded accrued
liability which reduced other expense by approximately $152,000 in 1994.  Annual
pension expense and additional, merger-related, pension costs increased the
Bank's pension expense by $204,000 in 1995.  Increases in data processing costs
over 1994 of $45,000 and an increase in occupancy expense of $106,000 due to a
reduction in the value of a lease intangible asset also contributed to the
change in other expenses.

YEAR ENDED JUNE 30, 1994 COMPARED TO YEAR ENDED JUNE 30, 1993

Net Interest Income
-------------------

Interest and fees on loans decreased $443,000 from that in 1993.  The
fluctuation was caused by a decline in the weighted average loan portfolio yield
of .58% which was partially offset by an increase in the average daily balance
of loans outstanding of $5,194,000.  Interest income on investments, mortgage-
backed securities, and other interest-bearing assets decreased $100,000 as a
result of a 1.04% decrease in the weighted average yield and a decrease in the
average daily balance of $1,725,000.  Total interest expense of the Bank
decreased $762,000 for 1994.  The average daily balance of customer deposits in
1994 was $340,000 lower than in the prior year and the weighted average rate
paid on deposits decreased .72%.  In addition, the Bank capitalized $35,500 of
interest on the Shorewalk at Geist condominium project in 1994 as compared to
$51,000 in 1993.  The results of the above fluctuations was an increase in net
interest income of $228,000 from the previous year.

Provision for Loan Losses
-------------------------

During fiscal 1994, the Bank recorded a provision for loan losses of $122,000
and recorded charge-offs (net of recoveries) totaling $45,000.  In the prior
year, net charge-offs totaled $72,000 with a provision for loan losses of
$90,000.

Other Income
------------

Total noninterest income of the Bank increased $17,000 to $600,000 for 1994.
During the current year, the Bank sold loans in the secondary market totaling
$9,802,000 and realized net gains of $78,000 as compared to net gains in the
prior year of $122,000.  The Bank actively manages a trading account portfolio
and realized net losses in 1994 of $69,000, as compared to $101,000 in the prior
year, on sales from the trading account as well as a mutual fund.

Other Expense
-------------

During the fourth quarter of fiscal 1994, the Bank decided not to develop the
final phase of the Shorewalk project and reduced its carrying value in the
project by $2,463,000 to its estimated fair value based on an independent
appraisal.  Excluding that charge, the Bank's noninterest expense increased
$121,000.  Also during the fourth quarter of fiscal 1994, the Bank reached an
agreement with the Homeowners Association at Shorewalk for $115,500 to settle
claims assessed in a previous year.  This settlement was accrued and is included
in miscellaneous expenses in 1994.

Prior to 1994, the Bank's defined benefit pension plan was a single-employer
plan sponsored by First United.  Effective July 1, 1993, the Bank elected to
participate in a multi-employer plan.  As a result of this change in plans, the
Bank was able to reduce its accrued pension liability to its estimated unfunded
accrued liability which reduced other expenses by approximately $152,000 in
1994.

                                      -5-

The Bank's federal deposit insurance premium in 1994 was $89,000 higher than in
1993 as a result of its secondary reserve credit recapture in the prior year.
The Bank also converted to a new service bureau for data processing services in
1994 which resulted in an increase in data processing costs of $36,000.

The following table sets forth, for the indicated periods, First United's return
on assets, return on equity, and equity-to-assets ratio:

LIQUIDITY AND CAPITAL RESOURCES

First United's liquidity, represented by cash and cash equivalents, is a result
of its operating, investing, and financing activities.  During the year ended
June 30, 1995, the Bank's liquidity increased $576,000.  The major sources of
cash were from financing and operating activities which generated $11,106,000.
Operating activities including proceeds of $3,039,000 from the sale of trading
account assets provided $1,963,000 of cash and financing activities included
additional Federal Home Loan Bank advances of $10,000,000.  The major uses of
cash during the year included an increase in total loans of $10,693,000.

Under the Financial Institutions Reform, Recovery and Enforcement Act of 1989
("FIRREA") and regulatory capital regulations, at June 30, 1995, the Bank was
required to have (i) core capital equal to 3% of adjusted total assets, (ii)
tangible capital equal to 1.5% of adjusted total assets, and (iii) total capital
equal to 8% of risk-weighted assets.  The Bank met the fully phased-in risk-
based capital requirement of 8% on July 1, 1995.

The OTS has adopted an interest rate risk component to its risk-based capital
requirements to be effective September 1, 1995.  Under the new requirement, if a
Bank's market value of portfolio equity decreases by more than two per cent of
total assets from a 200 basis point change in interest rates, it is deemed to
have excessive interest rate risk.  In such cases, the Bank will be required to
reduce its total capital by one half the amount by which the change exceeds two
per cent of total assets.  Based on the calculations provided by the OTS, First
United would not be affected by this requirement if it were in effect as of June
30, 1995.

At June 30, 1995, the Bank exceeded all current OTS regulatory capital
requirements as follows (in thousands):

IMPACT OF INFLATION
</TABLE>

The consolidated financial statements and related data presented herein have
been prepared in accordance with generally accepted accounting principles.
These principles require the measurement of financial position and operating
results in terms of historical dollars, without considering changes in the
relative purchasing power of money over time due to inflation.

The primary assets and liabilities of First United are monetary in nature.  As a
result, interest rates have a more significant impact on First United's
performance than the effects of general levels of inflation.  Interest rates,
however, do not necessarily move in the same direction or with the same
magnitude as the price of goods and services, since such prices are affected by
inflation.  In a period of rapidly rising interest rates, the liquidity and
maturity structure of First United's assets and liabilities are critical to the
maintenance of acceptable performance levels.  For a discussion of First
United's efforts to restructure its assets and to reduce its vulnerability to
changes in interest rates, see "Asset/Liability Management."

                                      -6-
<PAGE>
 
The principal effect of inflation, as distinct from levels of interest rates, on
the Bank's earnings is in the area of other expense.  Such expense items as
salaries, employee benefits and occupancy costs may be subject to increases as a
result of inflation.  An additional effect of inflation is the possible increase
in dollar value of the collateral securing loans made by the Bank.  First United
is unable to determine the extent, if any, to which the properties securing its
loans have appreciated in dollar value due to inflation.

MARKET PRICE AND DIVIDENDS

First United converted from mutual to stock form effective March 27, 1987 (the
"Conversion").  First United's common stock, par value $.01 per share ("Common
Stock"), is quoted on the National Association of Securities Dealers Automated
Quotation system ("NASDAQ") under the symbol "FUSB".

For the past eight fiscal quarters, the high and low bid prices, as reported by
NASDAQ, were as follows:

Such over-the-counter quotations reflect inter-dealer prices, without retail
mark-up, mark-down or commission, and may not necessarily represent actual
transactions.  As of June 30, 1995, there were approximately 375 shareholders of
record of the Bank's Common Stock.

The Bank does not have an established policy of paying regular dividends.
During 1994, the Bank paid dividends of $.12 per share in March and June.

First United may adopt a policy of paying additional dividends in the future,
subject to the limitations prescribed by the federal regulations discussed
below, when the board of Directors of the Bank deems it to be appropriate.
Adoption of such a policy will depend on First United's net earnings, financial
position and capital requirements as well as economic conditions and other
factors.  Accordingly, no assurance can be given regarding the amount or timing
of future dividend payments, if any.

The Bank may not declare or pay a cash dividend or repurchase any of its capital
stock if the effect thereof would cause the net worth of the Bank to be reduced
below the amount required for the liquidation account.  Additionally, dividends
are subject to OTS distribution regulations which limit the amount of cash
dividends which may be declared by savings associations based on capital levels.

                        Report of Independent Auditors


To the Stockholders and
 Board of Directors
First United Savings Bank


We have audited the accompanying consolidated statements of condition of First
United Savings Bank, fsb. and subsidiaries as of June 30, 1995 and 1994, and the
related consolidated statements of income, stockholders' equity and cash flows
for each of the three years in the period ended June 30, 1994.  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 audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of First United
Savings Bank, fsb. and subsidiaries at June 30, 1995 and 1994, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended June 30, 1995, in conformity with generally

1. SIGNIFICANT ACCOUNTING POLICIES

MERGER AGREEMENT

On September 24, 1994, First United Savings Bank entered into  the Amended and
Restated Agreement of Affiliation and Merger with Old National Bankcorp,
Evansville, Indiana ("ONB").  It is expected that this merger will be
consummated by the end of 1995.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of First United
Savings Bank, fsb. ("the Bank") and its wholly owned subsidiaries, Greenmark,
Inc. and Kirkwood Service Corp., Inc.  All significant intercompany balances and
transactions have been eliminated.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents consist of cash and interest-bearing deposits.
Interest-bearing deposits are available on demand.

TRADING ACCOUNT ASSETS

Certain investments in mutual funds are held for trading purposes and are stated
at market value.

INVESTMENT AND MORTGAGE-BACKED SECURITIES

In May 1993, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities," effective for fiscal years beginning after December
15, 1993.  Under the new rules, debt securities that the Bank has both the
positive intent and ability to hold to maturity are carried at amortized cost.
Debt securities that the Bank does not have the positive intent and ability to
hold to maturity and all marketable equity securities are to be classified as
available-for-sale or trading and carried at fair value.  Unrealized holding
gains and losses on securities classified as available-for-sale are to be
carried as a separate component of shareholders' equity.  Unrealized holding
gains and losses on securities classified as trading are reported in earnings.

            Notes to Consolidated Financial Statements (continued)



1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Presently, the Bank classifies its investment and mortgage-backed securities as
held-for-investment.  Investment securities are stated at cost adjusted for
amortization of premium and accretion of discount, both of which are computed by
a method that approximates a level yield.  Gains or losses on the sale of these
investments are based on the adjusted cost of the specific investment.  The Bank
has the ability and intention to hold investment and mortgage-backed securities
to maturity and, therefore, such securities are carried at amortized cost.  The
Bank first applied the new rules starting in the first quarter of fiscal 1995.
Application of the new rules did not have an impact on stockholders' equity as
of July 1, 1994.

STOCK IN FEDERAL HOME LOAN BANK OF INDIANAPOLIS

Stock in the Federal Home Loan Bank of Indianapolis is stated at cost.  The
amount of stock held is determined by regulation.

LOANS RECEIVABLE

The Bank primarily originates adjustable rate loans and intends to hold such
loans for long-term investment.  Accordingly, such loans are carried at cost.
Fixed rate loans originated are generally sold.  Fixed rate loans held for sale,
which were immaterial at June 30, 1995, are carried at the lower of cost or
market value.

The Bank has a first mortgage lien on all property on which mortgage,
participation or purchased loans are made.  Further, a portion of certain
mortgage loan balances is insured by private or government guaranty insurance
policies.  Interest income is computed monthly based upon the principal amount
of the loans outstanding.

REAL ESTATE OWNED AND IN JUDGMENT

Real estate owned and in judgment arises from loan foreclosure or deed in lieu
of foreclosure and is recorded at the lower of cost (the unpaid balance at the
date of acquisition plus foreclosure and other related costs) or fair value.
Subsequent to acquisition, an allowance is recorded for any excess of carrying
value over fair value minus estimated selling costs. Costs of improvements made
to facilitate sale are capitalized; costs of holding the property are charged 
to expense.

                                                                               7

1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

DIRECT INVESTMENT IN REAL ESTATE

The Bank acts as developer for a condominium project (i.e. Shorewalk at Geist)
in Indianapolis, Indiana which it acquired in connection with the acquisition of
Fountain Federal Savings and Loan Association of Bloomington, Indiana in 1988.
The Bank had an ownership interest in real estate associated with a second
condominium project in Indianapolis also acquired in connection with the merger
but sold this interest effective June 30, 1993. Construction and holding costs
have been capitalized and revenue received has been used to reduce the Bank's
basis in the projects.  A valuation allowance of $625,000 was established during
1992.  During the quarter ended June 30, 1994, the Bank decided not to develop
the final phase of the Shorewalk project and reduced its carrying value in the
project by $2,463,049 to its estimated fair value based on an independent
appraisal.  During the quarter ended December 31, the Bank reduced Shorewalk's
carrying value by an additional $200,000.  On June 30, 1995 the Bank sold
Shorewalk on contract to an independent third party.  The contract requires
payment, in advance, on lot by lot basis as the purchaser commences development
of each lot.

ALLOWANCE FOR LOAN LOSSES

An allowance for loan losses is maintained at a level management believes
adequate to absorb potential losses in the loan portfolio.  Management's
determination of the adequacy of the allowance is based on their evaluation of
the related assets, past experience and current economic and market conditions.

PREMISES AND EQUIPMENT

Premises and equipment is recorded on the basis of cost.  Depreciation is
computed on the straight-line method over the estimated useful lives of the
related assets.

EARNINGS PER SHARE

Earnings per share is computed by dividing net income for the period by the
weighted average number of shares outstanding.

The Bank's loan portfolio consists generally of loans to individuals and
businesses located in its central Indiana marketplace.

In May 1993, the Financial Accounting Standards Board issued Statement No. 114,
"Accounting by Creditors For Impairment of a Loan."  The Bank plans to adopt
this standard on July 1, 1995 and does not expect the adoption to have a
material impact on financial position or results of operations.

                                                                              11

5. DEPOSITS (CONTINUED)

The average interest rates represent the weighted average interest rate in
effect at the end of the period. Accrued interest payable, which relates
primarily to certificate accounts, totaled approximately $91,000 and $80,000 at
June 30, 1995 and 1994, respectively, and is included in other liabilities in
the consolidated statements of condition.  As of June 30, 1995, the Bank held
$17,344,000 of deposits of $100,000 or more.

6. FEDERAL HOME LOAN BANK ADVANCES

The Bank utilized variable rate Federal Home Loan Bank advances at various
periods throughout the year. Advances outstanding as of June 30, 1995 are due in
the first quarter of fiscal 1995, and the interest rate adjusts daily (6.79% at
June 30, 1995). The advances are secured by approximately $32,300,000 of first
mortgage loans.

In addition, the Bank has a $500,000 line of credit with the Federal Home Loan
Bank of Indianapolis which is secured by first mortgage loans.  As of June 30,
1995, no amounts were outstanding under this line of credit.

7. INCOME TAXES

The Bank has qualified under provisions of the Internal Revenue Code which
permit it to deduct from taxable income a provision for bad debts which differs
from the provisions for such losses recognized in the consolidated statements of
operations.  Accordingly, retained earnings at June 30, 1994 includes income of
approximately $3,448,000, (approximately $1,172,000 of unrecognized deferred tax
liability) for which no provision for federal income taxes has been made.  If,
in the future, this portion of retained earnings is used for any purpose other
than to absorb bad debt losses, federal income taxes will be imposed at the then
applicable rates.

                                                                              13

7. INCOME TAXES (CONTINUED)

The Bank obtained tax operating loss carryforwards from the acquisition of a
savings institution in 1988 and recognized tax operating losses for 1993 and
1995.  The remaining tax loss carryforwards at June 30, 1995 of approximately
$5,286,000 expire as follows:  2002-$344,000; 2003-$598,000; 2004-$11,000; 2005-
$9,000; 2008-$1,471,000, and 2010-$2,853,000

8. EMPLOYEE BENEFIT PLANS

The Bank has a defined benefit pension plan covering substantially all of its
employees.  Prior to July 1, 1993, these benefits were provided under a separate
plan sponsored by the Bank.  Effective July 1, 1993, the Bank elected to
participate in Pentegra, formerly known as the Financial Institutions Retirement
Fund, a multi-employer, industry-sponsored plan.  Benefits are based on years of
service and the employee's compensation during employment.  The Bank transferred
plan assets to Pentegra and Pentegra assumed plan benefit obligations.  The
excess of the benefit obligations assumed by Pentegra over the fair value of the
assets transferred represents an unfunded accrued liability which is to be
funded by the Bank, in addition to normal service cost contributions, over a 15
year period through 2009.  At June 30, 1995 and 1994, respectively, the
estimated unfunded accrued liability was approximately $82,500 and $63,000.

Pension expense for 1995 was approximately $102,000.  Information regarding the
Bank's portion of Pentegra plan assets and accumulated plan benefits is not
available.  According to Pentegra, plan assets exceeded vested benefits as of
July 1, 1994, the date of the most recent actuarial valuation.

In addition to providing pension benefits, the Bank adopted two supplemental
benefit plans during 1987 - one for those employees who have completed ten years
of service to the Bank and another for the Bank's directors.  Under these plans,
the participants shall receive additional retirement benefits for the ten years
following retirement (generally age 65).  During 1994, the Bank adopted
changes to the plans thereby making them defined contribution plans.  The cost
of the benefit was recognized as the required contributions were made.
Previously, the cost of these benefits was being recognized generally over the
remaining years of service to the Bank of each participant utilizing the
"projected unit credit" actuarial method.  The Bank recognized expense of
$67,000, $52,000 and $32,000 in 1995, 1994 and 1993, respectively.

9. STOCKHOLDERS' EQUITY

In 1986, the Board of Directors adopted a Plan of Conversion to convert the Bank
from a mutual to a stock institution.  At the time of the conversion, a
liquidation account was established in an amount equal to the Bank's net worth
as reflected in the latest statement of condition used in its final conversion
offering circular. The liquidation account is maintained for the benefit of
eligible deposit account holders who maintain their deposit accounts in the Bank
after conversion.  In the event of a complete liquidation (and only in such
event), each eligible deposit account holder will be entitled to receive a
liquidation distribution from the liquidation account in the amount of the then
current adjusted subaccount balance for deposit accounts then held, before any
liquidation distribution may be made to stockholders.  Except for the repurchase
of stock and payment of dividends, the existence of the liquidation account will
not restrict the use or application of net worth.  The initial balance of the
liquidation account was $5,267,293.

The Bank may not declare or pay a cash dividend or repurchase any of its capital
stock if the effect thereof would cause the net worth of the Bank to be reduced
below the amount required for the liquidation account.  In addition, the Bank
may not declare a dividend in excess of net earnings for the calendar year to
date plus one-half of the amount by which regulatory capital exceeds the fully
phased-in capital requirements imposed by the Office of Thrift Supervision
(OTS).

The Bank is required, pursuant to OTS regulations, to meet various minimum
capital requirements.  Following is a reconciliation of net worth, as determined
under generally accepted accounting principles (GAAP net worth), to core
capital, tangible capital and risk-based capital and a comparison of the
respective capital amounts to the minimum balances, and percentages of
regulatory defined assets, required by the OTS at June 30, 1995 (in thousands):

10. STOCK COMPENSATION PLANS

The Board of Directors of the Bank adopted a stock option plan in connection
with the conversion in 1986 from a mutual to a stock institution.  Effective
with the stock conversion, the Board of Directors granted to key officers and
directors options to purchase 21,500 shares of Common Stock at the conversion
price of $10 per share.  Options granted have terms of ten years (12,000 shares)
and ten years and one day (9,500 shares) and are exercisable six months after
the date of grant.  The plan also provides for each outside director to receive
an additional option to purchase 200 shares of common stock each year at the
date of the annual meeting.

12. LOANS TO RELATED PARTIES

Certain directors and officers of the Bank were loan customers in the ordinary
course of business during 1995 and 1994. The aggregate dollar amount of these
loans was $449,000 and $547,000 on June 30, 1995 and 1994, respectively. During
1995, $22,000 of new loans were made and repayments totaled $120,000. All of the
loans were made on substantially the same terms, including interest rate and
collateral, as those prevailing at the time for comparable transactions with
unrelated parties.

During 1991, the Bank received a grant from the Federal Home Loan Bank of
Indianapolis, under the Affordable Housing Program, to be used to support below
market financing for twenty rental units to be developed for low-income and/or
disabled families.  The Bank originated $415,000 and $85,000 in loans during
1995 and 1994, respectively, to Opportunity Housing, Inc. of Putnam County, a
not-for-profit agency that builds and rents such low-income housing.  The
proceeds from the grant are being used to subsidize loans granted to the agency.
Certain officers of the Bank are also directors of Opportunity Housing, Inc.

13. LITIGATION

The Bank is subject to certain legal proceedings and claims which have arisen in
connection with a customer's investment held by the Bank.  The liability, if
any, associated with these matters is not determinable at June 30, 1995.  It is
the opinion of management that the ultimate resolution of these matters will not
have a materially adverse effect on the Bank's financial position.
