                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q. WHY DO FIRST COMMUNITY AND MAINSOURCE FINANCIAL GROUP, INC. WANT TO MERGE?

A. First Community believes that the consideration offered to its shareholders
is fair and that MainSource Financial Group, Inc. is a sound merger partner.
First Community wants its customers in First Community service areas to be
served effectively and MainSource Financial desires to expand its presence in
those service areas.

Q. HOW WILL I BENEFIT?

A. The First Community Board of Directors believes that you will benefit by
receiving $21.00 in cash in exchange for each common share of First Community
that you own upon the consummation of the merger.

Q. IF I DO NOT FAVOR THE TRANSACTION, WHAT ARE MY RIGHTS?

A. If you are a shareholder of First Community as of the record date and you do
not vote in favor of the merger agreement, you will have the right under Indiana
Code Section 23-1-44-8 to demand the fair value for your common shares of First
Community. The right to make this demand is generally known as "dissenters'
rights." To perfect your dissenters' rights, you must:

o        deliver to First Community before the vote is taken a written notice of
         your intent to demand payment of the fair value of your common shares
         if the merger is effectuated;

o        not vote your common shares in favor of the merger; and

o        otherwise comply strictly with all of the requirements of Indiana Code
         Section 23-1-44-1 and following.

Q. WILL I OWE ANY FEDERAL INCOME TAX AS A RESULT OF THE MERGER?

A. The federal income tax consequences for each shareholder will depend in part
upon your specific situation. No ruling has been or will be sought from the
Internal Revenue Service as to the federal income tax consequences of the
merger. Generally, you will recognize a gain with respect to the cash payment
you receive, depending upon your basis in the First Community shares that you
own.

Q. WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A: We plan to complete the transaction as soon as possible after the Special
Meeting, assuming the required shareholder approval is obtained. The transaction
is also subject to the approval of federal bank regulatory authorities and the
satisfaction of other closing conditions. We expect the transaction to be
completed in the second quarter of calendar year 2003.

Q. WHEN AND WHERE WILL THE SPECIAL MEETING TAKE PLACE?

A. The Special Meeting will be held at _______ a.m., Eastern Standard Time, on
__________, 2003, at the _____________________, _______________________,
Franklin, Indiana.

                                       1


Q. WHAT DO I NEED TO DO NOW?

A: Just mail your completed, signed and dated proxy card in the enclosed return
envelope as soon as possible so that your First Community shares will be
represented at the Special Meeting.

Q. WHAT IS THE DIFFERENCE BETWEEN HOLDING SHARES AS A SHAREHOLDER OF RECORD AND
AS A BENEFICIAL OWNER?

A: Many First Community shareholders hold their shares through a stockbroker,
bank or other nominee rather than directly in their own name. As summarized
below, there are some distinctions between shares held of record and those owned
beneficially.

     SHAREHOLDER OF RECORD

     If your shares are registered directly in your name with First Community's
transfer agent, you are considered, with respect to those shares, the
shareholder of record and these proxy materials are being sent directly to you
by First Community. As a shareholder of record, you have the right to grant your
proxy directly to First Community or to vote in person at the Special Meeting.
First Community has enclosed a proxy card for your use.

     BENEFICIAL OWNER

     If your shares are held in a stock brokerage account or by a bank or other
nominee, you are considered the beneficial owner of the shares held in street
name and these proxy materials are being forwarded to you by your broker or
nominee who is considered, with respect to those shares, the shareholder of
record. As the beneficial owner, you have the right to direct your broker on how
to vote. Your broker or nominee has enclosed a voting instruction card for your
use. If you are a First Community shareholder whose shares are not registered in
your own name, you will need additional documentation from your record holder to
attend the Special Meeting and to vote your shares at the Special Meeting.

Q. IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
SHARES FOR ME?

A: Your broker will vote your First Community shares with respect to the merger
agreement only if you provide instructions on how to vote. You should follow the
directions provided by your broker regarding how to instruct your broker to vote
your shares.

Q. MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A: Yes. You can change your vote at any time before your proxy is voted at the
Special Meeting. If you are the record holder of the shares, you can do this in
three ways. First, you can send First Community a written statement that you
would like to revoke your proxy, if such written notice is received prior to the
date of the Special Meeting. Second, you can send First Community a new signed
and later-dated proxy card, provided that such proxy card is received prior to
the date of the Special Meeting. Third, you can attend the Special Meeting and
vote in person. However, your attendance alone will not revoke your proxy.

                                       2


       For shares held beneficially by you, but not as record holder, you may
change your vote by submitting new voting instructions to your broker or
nominee.

Q. HOW CAN I VOTE MY SHARES IN PERSON AT THE MEETING?

A: Shares held directly in your name as the shareholder of record may be voted
in person at the Special Meeting. If you choose to attend, please bring the
enclosed proxy card or proof of identification.

Q. HOW WILL MY SHARES BE VOTED IF I RETURN A BLANK PROXY CARD?

A. If you are the record holder of the shares and you sign and send in your
proxy and do not indicate how you want to vote, your proxy will be counted as a
vote in favor of the merger agreement.

Q. WHAT WILL BE THE EFFECT IF I DO NOT VOTE?

A. Not voting will have the same effect as voting against the merger agreement.

Q. SHOULD I SEND IN MY STOCK CERTIFICATE NOW?

A: No. If the merger is completed, you will receive written instructions for
exchanging your share certificates.

Q. WHO CAN ANSWER MY QUESTIONS ABOUT THE MERGER OR HOW I CAN SUBMIT MY PROXY?

A. If you have more questions about the merger or how to submit your proxy,
please call Albert R. Jackson, III at (317) ___-______.

                                   THE MERGER
                                   (PAGE ___)

         The directors and executive officers have interests in the merger in
addition to the interests of all other shareholders. Those interests include the
following:

         o        Each outstanding First Community option, including those held
                  by directors and executive officers, will be cancelled and

         Completion of the merger depends upon the satisfaction of a number of
conditions, including, among others, the following:

certain of the closing conditions may be waived by the party entitled to assert
them. The First Community Board of Directors does not currently intend to seek
shareholder approval of any waiver of any condition.

         o        by the Board of Directors of MainSource Financial or First
                  Community if the merger is not completed on or before June 30,
                  2003, or if any of the conditions of the merger are not
                  satisfied.

                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS
                                   (PAGE ___)

         First Community shareholders may recognize gain, in certain
circumstances taxable as ordinary income, with respect to the cash consideration

                               THE SPECIAL MEETING

INTRODUCTION

         This document is being furnished to the shareholders of First Community
in connection with the solicitation of proxies by the First Community Board of
Directors for use at the Special Meeting of Shareholders of First Community
shareholders to be held on _________, _____________, 2003, at _____ a.m.,
Eastern Standard Time, at the _________________________________
________________, Franklin, Indiana, and at any adjournments or postponements of
the Special Meeting. Each copy of this document mailed to the shareholders of
First Community is accompanied by a proxy card furnished in connection with the
solicitation of proxies by the First Community Board of Directors for use at the
Special Meeting.


MATTERS TO BE CONSIDERED; BOARD OF DIRECTORS RECOMMENDATION

         At the Special Meeting, First Community shareholders will be asked to
vote upon the following resolution:

                  Resolved, that the Agreement and Plan of Merger, dated as of
         March 27, 2003, by and among MainSource Financial Group, Inc., FCBY
         Merger Corporation and First Community Bancshares, Inc., a copy of
         which is attached to the proxy statement of First Community dated
         ____________, 2003, and the transactions contemplated thereby,
         including the merger of First Community with and into FCBY Merger
         Corporation, which is a wholly-owned subsidiary of MainSource
         Financial, and the cancellation of each outstanding common share of
         First Community in exchange for the right to receive $21.00 cash, be
         and they hereby are, adopted and approved.

         The Board of Directors knows of no business that will be presented for
consideration at the Special Meeting other than the matters described in this
document.

         The First Community Board of Directors has determined that the adoption
of the merger agreement is in the best interests of First Community
shareholders. ACCORDINGLY, THE FIRST COMMUNITY BOARD OF DIRECTORS RECOMMENDS
THAT SHAREHOLDERS VOTE "FOR" THE ADOPTION OF THE MERGER AGREEMENT AND THE
APPROVAL OF THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT, INCLUDING THE
MERGER. SEE "THE MERGER - BACKGROUND AND REASONS FOR THE MERGER."

          SHAREHOLDERS ARE REQUESTED TO COMPLETE, DATE, SIGN AND RETURN THE
ACCOMPANYING PROXY CARD IN THE ENCLOSED POSTAGE-PAID ENVELOPE. FAILURE TO RETURN
A PROPERLY EXECUTED PROXY CARD OR TO VOTE AT THE SPECIAL MEETING WILL HAVE THE
SAME EFFECT AS A VOTE AGAINST ADOPTION OF THE MERGER AGREEMENT.

RECORD DATE AND VOTING

         Only the holders of record of First Community common shares as of the
close of business on _______________, 2003, are entitled to notice of and to
vote at the Special Meeting. At the close of business on the record date, there
were _________ common shares of First Community outstanding and entitled to
vote, held by approximately ___ shareholders of record and beneficially by
approximately ___ shareholders. Directors and executive officers of First
Community (as a group) were entitled to vote _______ common shares of First

                                       8


Community, or approximately ____% of the outstanding votes entitled to be cast
at the Special Meeting, and the directors have executed agreements to vote their
shares in favor of the merger agreement. [MainSource Financial owned and was
entitled to vote 20,000 shares of First Community on the voting record date.]
Holders of record of First Community common shares as of the close of business
on the record date are entitled to one vote per share on any matter voted on at
the Special Meeting.

         The presence, either in person or by proxy, of the holders of a
majority of the outstanding common shares of First Community as of the record
date is necessary to constitute a quorum at the Special Meeting. Abstentions
count for the purpose of determining a quorum at the Special Meeting.

         SHAREHOLDERS SHOULD NOT FORWARD ANY SHARE CERTIFICATES WITH THEIR PROXY
CARDS. IF THE MERGER IS CONSUMMATED, SHARE CERTIFICATES SHOULD BE DELIVERED IN
ACCORDANCE WITH INSTRUCTIONS SET FORTH IN A LETTER OF TRANSMITTAL, WHICH WILL BE
SENT TO SHAREHOLDERS BY MAINSOURCE BANK, GREENSBURG, INDIANA, IN ITS CAPACITY AS
THE EXCHANGE AGENT, PROMPTLY AFTER THE MERGER IS EFFECTIVE.

VOTE REQUIRED

         The affirmative vote of the holders of at least a majority of the
outstanding common shares of First Community entitled to vote on the matters to
be acted upon is required to adopt the merger agreement. THE FAILURE TO SUBMIT A
PROXY CARD OR VOTE IN PERSON AT THE SPECIAL MEETING HAS THE SAME EFFECT AS A
VOTE AGAINST ADOPTION OF THE MERGER AGREEMENT. ABSTENTIONS AND FAILURES TO VOTE
ON THIS MATTER BY A BROKER ALSO HAVE THE SAME EFFECT AS A VOTE AGAINST THE
MERGER AGREEMENT. BROKERS WHO HOLD COMMON SHARES OF FIRST COMMUNITY AS NOMINEES
WILL NOT HAVE DISCRETIONARY AUTHORITY TO VOTE SHARES WITH RESPECT TO THE MERGER
AGREEMENT ABSENT INSTRUCTIONS FROM THE BENEFICIAL OWNER. THEREFORE, BY NOT
GIVING SUCH INSTRUCTIONS, YOU WILL IN EFFECT BE VOTING AGAINST THE MERGER.

         The proxy holders named in the enclosed proxy card will vote all common
shares of First Community represented by proxy cards that are properly signed
and returned by shareholders in accordance with the instructions contained on
the proxy card. You may specify your voting choices by marking the appropriate
boxes on the proxy card. IF YOU PROPERLY SIGN AND RETURN THE PROXY CARD SENT TO
YOU BY FIRST COMMUNITY BUT DO NOT SPECIFY YOUR VOTING CHOICES, YOUR SHARES WILL
BE VOTED "FOR" THE ADOPTION OF THE MERGER AGREEMENT, AS RECOMMENDED BY THE BOARD
OF DIRECTORS.

         The First Community Board of Directors is not aware of any matters
other than those set forth in the Notice of Special Meeting of Shareholders of
First Community that may be brought before the Special Meeting. If any other
matters properly come before the Special Meeting, the persons named in the
accompanying proxy will vote the shares represented by all properly executed
proxies on such matters in their discretion.

REVOCABILITY OF PROXIES

         A shareholder of record may revoke a proxy at any time prior to its
exercise by:

         o        delivering to First Community Bancshares, Inc., 210 East
                  Harriman, Bargersville, Indiana 46106, Attention: Albert R.
                  Jackson, III, a written notice of revocation prior to the
                  Special Meeting,

         o        delivering to First Community Bancshares, Inc., 210 East
                  Harriman, Bargersville, Indiana 46106, Attention: Albert R.
                  Jackson, III, a duly executed proxy bearing a later date prior
                  to the Special Meeting, or

         o        attending the Special Meeting and voting in person.

         For shares held beneficially, but not as record holder, a shareholder
may change a previous vote by submitting new voting instructions to the broker
or nominee.

         The presence of a shareholder at the Special Meeting will not in and of
itself automatically revoke such shareholder's proxy. If shares are held of
record, you can vote at the Special Meeting. A beneficial holder may not vote or
revoke a proxy at the Special Meeting unless such shareholder has received a
properly executed proxy from the broker or nominee.

SOLICITATION OF PROXIES

         All expenses of First Community's solicitation of proxies, including
the cost of mailing this document to you, will be paid by First Community.

         Proxies may be solicited from shareholders by directors, officers and
employees by mail, in person or by telephone, facsimile or other means of
communication. Such directors, officers and employees will not receive
additional compensation, but may be reimbursed for their reasonable
out-of-pocket expenses in connection with such solicitation. Arrangements will
be made with brokerage houses, custodians, nominees and fiduciaries for the
forwarding of proxy solicitation materials to beneficial owners of shares held
of record by such brokerage houses, custodians, nominees and fiduciaries, and
First Community will reimburse such brokerage houses, custodians, nominees and
fiduciaries for their reasonable expenses incurred in connection with such
solicitation.

DISSENTERS' RIGHTS

         The Indiana Business Corporation Law provides shareholders of merging
corporations with certain dissenters' rights. The dissenters' rights of First
Community shareholders are set forth in Indiana Code Chapter 23-1-44, a copy of
which is attached to this Proxy Statement as Annex C. Shareholders of First
Community will be entitled to dissenters' rights only upon strict compliance
with procedures of the Indiana Business Corporation Law.

         The Indiana Business Corporation Law provides that shareholders of
First Community have the right to demand payment for the fair value of their
shares of First Community common stock immediately before the merger becomes
effective, excluding any appreciation or depreciation in the value in
anticipation of the merger, unless a court determines that such exclusion would
be inequitable. To claim this right, the shareholder must first:

                                       11


         o        Deliver to First Community, before the vote is taken, written
                  notice of the shareholder's intent to demand payment in cash
                  for the shareholder's shares if the merger is consummated, and

         o        Not vote in favor of the merger in person or by proxy.

         Dissenting shareholders may send their written notice to Albert R.
Jackson, III, Chief Executive Officer, First Community Bancshares, 34 West
Jefferson Street, P.O. Box 970, Franklin, Indiana 46160.

         If the merger is approved by First Community shareholders, MainSource
Financial will send notice of dissenters' rights to those shareholders
satisfying the above conditions no later than ten (10) days after shareholder
approval has occurred. The notice will state the procedures the dissenting
shareholder thereafter must follow to exercise dissenters' rights in accordance
with Indiana law.

         A shareholder of First Community who is sent such a notice must then:

         o        Demand payment for the shareholder's shares of First Community
                  common stock,

         o        Certify whether beneficial ownership of the shares of First
                  Community common stock was acquired before the dates set forth
                  in such notice; and

         o        Deposit the shareholder's certificates representing shares of
                  First Community common stock in accordance with the terms of
                  such notice.

         First Community shareholders who do not demand payment or deposit the
shareholder's certificates representing shares of First Community common stock
as required and within the applicable time period are considered to have voted
such shares of First Community common stock in favor of the merger and are not
entitled to receive payment for such shares under the dissenters' rights
provision of the Indiana Business Corporation Law.

         A shareholder who does not comply with the preliminary conditions
described above will not be entitled to dissenters' rights under the Indiana
Business Corporation Law. Shareholders who execute and return the enclosed proxy
but do not specify a choice on the merger proposal will be deemed to have voted
in favor of the merger and accordingly to have waived their dissenters' rights,
unless the shareholder revokes the proxy prior to its being voted.

         Upon consummation of the merger, MainSource Financial will pay each
dissenting shareholder who has fully complied with all statutory requirements
and MainSource Financial's notice, and who was the beneficial owner of the First
Community common stock prior to November 20, 2002 (the date that the merger was
first publicly announced), MainSource Financial's estimate of the fair value of
each share of First Community common stock as of the time immediately prior to
the merger, excluding any appreciation in value in anticipation of the merger.

         Dissenters who comply with the above procedures can object to the fair
value established by MainSource Financial by stating their estimate of the fair
value and demanding payment of the additional amount claimed as fair value.
MainSource Financial can elect to agree to the dissenters' fair value demand or

                                       12


can commence an action in the Johnson County Circuit or Superior Court for a
judicial determination of the fair value. The court may appoint appraisers to
determine the fair value. The cost of the proceeding, including compensation and
expenses of the appraisers and counsel for the parties and experts, will be
assessed against all parties to the action in such amounts as the court finds
equitable. Each dissenter made a party to the action will be entitled to receive
the amount, if any, by which the court finds the fair value of the dissenters'
shares, plus interest, exceeds the amount paid by MainSource Financial.

         The foregoing summary of the applicable provisions of Chapter 44 of
Title 23 of the Indiana Business Corporation Law is not intended to be a
complete statement of such provisions, and is qualified in its entirety by
reference to such Chapter, a copy of which is attached as Annex C. Any First
Community shareholder who intends to dissent from the merger should review the
text of Annex C carefully and should also consult with an attorney. Any
shareholder who fails to strictly follow the procedures described in the statute
will forfeit dissenters' rights.

                                   THE MERGER

GENERAL

         If the merger is consummated, First Community will be acquired by
MainSource Financial Group through the merger of First Community with and into a
wholly-owned subsidiary of MainSource Financial Group, with the wholly-owned
subsidiary being the surviving corporation.

Background of the MERGER

         During the past several years, First Community's Board of Directors has
periodically reviewed and assessed the consolidations occurring in the financial
services industry, particularly among community banks. The Board's goal in
performing these reviews was, and remains, to enhance shareholder value. In
September 2002, following the public announcement of a proposed merger between a
regional bank and a community bank in which the shareholders of the community
bank received an immediate premium on the trading value of their shares, the
Board engaged in a number of informal discussions regarding the proposed terms
of the merger. Soon thereafter, the Board decided to actively explore whether a
transaction with a third party was available and whether such a transaction
would be the best way to maximize shareholder value.

         In October 2002, director Frank Neese contacted the president of a
publicly traded financial institution, the Interested Party, to see if there was
interest in an acquisition of First Community. The Interested Party expressed a
desire to discuss a potential merger and a meeting between First Community and
the Interested Party was scheduled for October 22, 2002.

         On October 16, 2002, at the next regularly scheduled meeting of First
Community's Board of Directors, Mr. Neese informed the Board of his discussions
with the Interested Party. The Board granted permission for Mr. Neese, Chairman
of the Board Merrill Wesemann and Chief Executive Officer Albert R. Jackson,
III, to attend the October 22, 2002 meeting and to engage in informal
discussions regarding a potential merger.

         On October 22, 2002, Mr. Neese, Chairman Wesemann and Mr. Jackson
attended the meeting with representatives of the Interested Party. At this

                                       13


meeting First Community and the Interested Party executed a confidentiality
agreement, after which First Community agreed to provide additional financial
and other information to the Interested Party for its review. Additionally,
First Community and the Interested Party discussed the strategies of the
respective institutions, results of operation, future business plans and the
advantages and disadvantages of integrating the two companies.

         On October 29, 2002, Mr. Neese received a telephone call from the
President of the Interested Party in which he indicated that the Interested
Party had a high level of interest in further exploring a potential merger and
that a proposal would be delivered to First Community's Board of Directors at
its next regularly scheduled meeting on November 20, 2002. The Interested Party
further informed Mr. Neese of its preliminary valuation thoughts of $20.00 per
share in an all cash transaction. Mr. Neese reported this telephone call to
Chairman Wesemann and Mr. Jackson. Chairman Wesemann directed Mr. Neese to
contact the President of MainSource Financial, James Saner, to determine whether
MainSource Financial would also have an interest in meeting with representatives
of First Community to discuss a potential merger.

         In late October and early November, 2002, Mr. Neese held several
telephone conversations with Mr. Saner of MainSource Financial. During these
conversations, First Community shared substantially the same financial and other
information that had been provided to the Interested Party. Based on its
preliminary due diligence, MainSource Financial indicated its interest in
discussing potential merger opportunities with First Community and a meeting was
scheduled for November 12, 2002 at the offices of Chairman Wesemann. Mr. Neese,
Chairman Wesemann and Mr. Jackson attended the meeting on behalf of First
Community and Mr. Saner and Mr. Don Benziger, the Senior Vice President and
Chief Financial Officer of MainSource Financial, attended the meeting on behalf
of MainSource Financial. At the meeting, the parties discussed the integration
of the two financial institutions and the advantages and disadvantages of such a
transaction. MainSource Financial also expressed a high level of interest in
further pursuing merger discussions and indicated that a proposal for the
acquisition of First Community would be presented to the Board of Directors of
First Community at its November 20, 2002, board meeting.

         On November 20, 2002, during the meeting of the First Community Board
of Directors, two proposed letters of intent were presented to the directors.
The proposal from MainSource Financial offered the holder of each share of First
Community common stock $21.00 per share in cash. The proposal from the
Interested Party offered the holder of each share of First Community common
stock a combination of common stock of the Interested Party and cash with a
total valuation less than the offer presented by MainSource Financial.
Following a discussion of the terms of each proposal, including the type of
consideration to be received from each party, and the duties and
responsibilities of directors in merger transactions of this type, and after the
consideration of the factors set forth below under "Reasons for the Merger," the
First Community Board of Directors voted to accept the MainSource Financial
offer and directed the President of First Community to execute a letter of
intent containing the principle proposed terms of the merger. A joint press
release announcing the execution of the letter of intent was issued on the same
day.

         On January 15, 2003, the First Community Board voted to hire Austin
Associates, LLC to perform a financial analysis of the merger consideration to

                                       14


determine whether the proposed consideration was fair to the shareholders of
First Community from a financial point of view.

         During the next several months, MainSource Financial performed
additional due diligence on First Community. Additionally, management of First
Community and its counsel met with management and counsel to MainSource
Financial on several occasions to negotiate provisions of the definitive merger
agreement. The parties exchanged several drafts of the definitive merger
agreement before the Board met to discuss the definitive merger terms.

         On February 26, 2003, the Board of Directors of First Community met to
review and comment upon a proposed draft of the definitive merger agreement. The
Board commented on certain issues which remained outstanding from the previous
draft as well as new matters. The Board voted to approve the definitive merger
agreement, subject to obtaining a favorable fairness opinion from Austin
Associates, LLC and subject to the resolution of the remaining issues in the
merger agreement.

         On March 27, 2003, following final approval by the boards of directors
of First Community and MainSource Financial, the parties executed the definitive
merger agreement. Under the terms of the merger agreement, First Community will
merge with and into FCBY Acquisition Corp., a wholly-owned subsidiary of
MainSource Financial, with FCBY being the surviving entity. First Community Bank
& Trust will thereby become a wholly-owned subsidiary of FCBY, which is a
wholly-owned subsidiary of MainSource Financial. Each outstanding share of
common stock of First Community will be converted into the right to receive a
cash amount equal to $21.00. In addition, each outstanding option to purchase
First Community common stock will be converted into the right to receive a cash
amount equal to $21.00 less the exercise price of the option.

Reasons for the Merger

         In reaching its decision to approve the merger agreement, the First
Community Board consulted with management of First Community, as well as its
financial and legal advisors, and considered a variety of factors, including the
following:

o        The First Community Board's knowledge and analysis of the current
         environment of the financial services industry, which is characterized
         by rapid consolidation, increased opportunities for cross-industry
         expansion, evolving trends in technology and increasing nationwide and
         Internet competition;

o        The First Community Board's belief that the financial terms of the
         merger are fair to and in the best interests of First Community as a
         whole and First Community's shareholders;

o        The business, operations, financial condition, earnings and prospects
         of First Community and MainSource Financial. In making its
         determination, the First Community Board took into account the results
         of First Community's due diligence review of MainSource Financial;

o        The scale, scope, strength and diversity of operations, product lines
         and delivery systems that can be achieved by combining First Community
         and MainSource Financial;

                                       15


o        The First Community Board's belief that the merger represents:

         a.       an opportunity to leverage First Community's management,
                  infrastructure, products, marketing and business lines over a
                  larger consumer, business and corporate customer base through
                  MainSource Financial's geographically diverse network; and

         b.       the possibility of achieving expense savings and operating
                  efficiencies through, among other things, the elimination of
                  duplicative efforts;

o        The opinion of Austin Associates, LLC to the First Community Board
         that, based upon and subject to the considerations set forth in the
         opinion, the conversion price was fair from a financial point of view
         to First Community shareholders (see "Proposed Merger--Fairness Opinion
         of First Community's Financial Advisor");

o        The likelihood of the merger being approved by the appropriate
         regulatory authorities;

o        Consideration of the effect of the merger on First Community's other
         constituencies, including First Community's employees and the customers
         and communities served by First Community, including consideration of
         the opportunity for training, education and advancement of employees
         within MainSource Financial or one of its affiliated companies; and

o        The First Community Board's analysis of alternatives to merging with
         MainSource Financial, including merging with the Interested Party or
         other potential acquirors and its analysis of relevant price
         information from recent comparable bank mergers which occurred in the
         Midwest and across the United States.

         This discussion of the information and factors considered by the First
Community Board is not intended to be exhaustive, but it does include all
material factors considered by the First Community Board. In reaching its
decision to approve and recommend the merger, the First Community Board of
Directors did not assign any relative or specific weights to these factors, and
individual directors may have given differing weights to different factors.
Based upon the foregoing and other factors, the Board of Directors of First
Community concluded that it was in the best interests of First Community and its
shareholders to merge with MainSource Financial.

         FOR THE REASONS SET FORTH ABOVE, THE BOARD OF DIRECTORS OF FIRST
COMMUNITY HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AS ADVISABLE AND IN THE
BEST INTERESTS OF FIRST COMMUNITY AND ITS SHAREHOLDERS AND RECOMMENDS THAT THE
SHAREHOLDERS OF FIRST COMMUNITY VOTE FOR THE ADOPTION OF THE MERGER AGREEMENT.

OPINION OF FINANCIAL ADVISOR

         First Community retained Austin Associates, LLC ("Austin") to provide a
fairness opinion in connection with the merger. Austin is an investment banking
and consulting firm specializing in community bank mergers and acquisitions.
First Community selected Austin for this opinion on the basis of Austin's
experience and expertise in representing community banks in similar
transactions.

                                       16


         In conjunction with the signing of the merger greement, Austin rendered
a written opinion to First Community's board of directors that the terms
provided for in the merger agreement were fair, from a financial point of view,
to the shareholders of First Community.

         Austin was not directly involved with the solicitation of offers,
negotiations with MainSource Financial or any other party. Austin was not
involved in negotiating any parts of the merger agreement.

         The preparation of a fairness opinion involves various determinations
as to the most appropriate methods of financial analysis and the application of
those methods to the particular circumstances. It is, therefore, not readily
susceptible to partial analysis or summary description. Austin believes that a
partial review of the analyses and the facts considered in its analyses could
create an incomplete or inaccurate view of the process used and the conclusions
reached by Austin in rendering its opinion. You should consider the following
when reading the discussion of Austin's opinion:

         o        the opinion should be read in its entirety for a full
                  understanding of the procedures followed, assumptions made,
                  matters considered and qualifications and limitations of the
                  review undertaken by Austin in connection with its opinion.
                  The summary of Austin's opinion set forth in this proxy
                  statement is qualified in its entirety by reference to the
                  full text of the opinion that is attached as Annex B to this
                  document.

         o        Austin's opinion rendered in connection with the merger does
                  not constitute a recommendation to any First Community
                  shareholder as to how he or she should vote at the special
                  meeting.

         o        no limitations were imposed on Austin by First Community's
                  board of directors or its management with respect to the
                  investigations made or the procedures followed by Austin in
                  rendering its opinion.

         In performing its analyses, Austin made numerous assumptions with
respect to industry performance, business and economic conditions, and other
matters, many of which are beyond the control of First Community and MainSource
Financial and may not be realized. Any estimates contained in Austin's analyses
do not purport to be appraisals or necessarily reflect the prices at which the
companies or their securities may actually be sold. Except as described below,
none of the analyses performed by Austin was assigned a greater significance by
Austin than any other. The summaries of financial analyses include information
presented in tabular format. The tables should be read together with the text of
those summaries.

         Austin has relied, without independent verification, upon the accuracy
and completeness of the information it reviewed for the purpose of rendering its
opinion. Austin did not undertake any independent evaluation or appraisal of the
assets and liabilities of First Community or MainSource Financial. Austin has
not reviewed any individual credit files of First Community or MainSource
Financial and has assumed that First Community's and MainSource Financial's loan
loss reserves are, in the aggregate, adequate to cover losses. Austin's opinion
is based on economic, market and other conditions existing on the date of its
opinion, and on information as of various earlier dates made

                                       17


available to it which may not necessarily be indicative of current market
conditions.

In rendering its opinion, Austin made the following assumptions:

         o        the merger will be accounted for using purchase accounting in
                  accordance with generally accepted accounting principles;

         o        all material governmental, regulatory and other consents and
                  approvals necessary for the consummation of the merger would
                  be obtained without any adverse effect on First Community,
                  MainSource Financial or on the anticipated benefits of the
                  merger;

         o        First Community and MainSource Financial have provided all of
                  the information that might be material to Austin in its
                  review; and

In connection with its opinion, Austin reviewed:

         o        the Agreement;

         o        audited financial statements of MainSource Financial for the
                  five years ended December 31, 2001 and unaudited financial
                  statement summaries as of December 31, 2002;

         o        audited financial statements of First Community for the five
                  years ended December 31, 2001 and unaudited financial
                  statement summaries as of December 31, 2002;

In addition, Austin:

         o        compared the financial terms of the merger with the financial
                  terms, to the extent publicly available, of other recent
                  business combinations of financial institutions;

         o        considered the indication of value for First Community as
                  determined using a discounted cash flow approach and compared
                  the results to the MainSource Financial aggregate deal value;
                  and

         o        conducted such other studies, analyses, inquiries and
                  examinations, as Austin deemed appropriate.

         The following is a summary of all material analyses performed by Austin
in connection with its opinion provided to the First Community Board of
Directors as of March 27, 2003. The summary does not purport to be a complete
description of the analyses performed by Austin.

         Summary of Financial Terms of Agreement. Austin reviewed the financial
terms of the proposed transaction, including the form of consideration and the
resulting price per share to First Community common stock holders pursuant to
the proposed merger. Under the terms of the Agreement, each outstanding share of
First Community common stock will receive $21.00 in cash. The Agreement further
provides that stock options and convertible debt previously granted or issued by
First Community be converted into cash in an amount equal to the cash amount
less the exercise price.

                                       18


         Contribution Analysis. Austin compared the market capitalization of
MainSource Financial to First Community's aggregate deal value in the
transaction. Austin then considered First Community's contribution of certain
balance sheet and income statement measures. The following table provides
highlights to this analysis:

         (1)      Represents the transaction value at $21.00 per share plus
                  in-the-money value of stock equivalents.
         (2)      First Community's core income adjusted for normalized loan
                  loss provision expense of $250,000 in 2002

         With respect to the contribution of First Community's balance sheet and
income in the pro forma company, each measure would indicate First Community is
receiving a premium for its contribution in the pro forma company with the
exception of tangible book value.

         Merger Value. In rendering its opinion on March 27, 2003, Austin
considered the cash value per share to each common shareholder in First
Community. Based on 1,044,926 common shares at First Community, the aggregate
value to common shareholders equaled $21.9 million ($21.00 multiplied by
1,044,926 shares outstanding at First Community).

         In addition, MainSource Financial agreed to convert the 34,700
outstanding options of First Community into cash. These options are exercisable
at a weighted average price of $9.72 per share. Based on the $21.00 per share
value to First Community shareholders, the "in-the-money" value of the options
measures approximately $391,000 in the aggregate.

         First Community also has $1.0 million of convertible debt securities
which are convertible into 90,910 shares of common stock. MainSource Financial
agreed to convert the convertible debt into cash. Based on the $21.00 per share
value to First Community shareholders, the "in-the-money" value of the
convertible debt measures approximately $909,000 in the aggregate.

                                       19


         Therefore, when including the value of consideration for the options
and convertible debt of First Community, the aggregate value of the transaction
at March 27, 2003 was approximately $23.2 million.

         Austin Associates calculated that the indicated value of $23.2 million
represented:

         o        222 percent of book value at December 31, 2002;
         o        224 percent of tangible book value at December 31, 2002;
         o        19.6 times core net income for year end 2002;
         o        49.2 times stated net income for year end 2002; and
         o        8.8 percent premium over tangible equity as a percent of total
                  assets.

         Comparable Transaction Analysis. Austin reviewed certain information
relating to bank sale transactions in the Midwest and nationally announced since
January 1, 2001 with publicly available deal values. The following chart
highlights the criteria used to select guideline transactions for comparison to
the merger.

         Austin concluded that the multiples paid by MainSource Financial for
First Community either approximate or exceed the median multiples paid for
comparable bank transactions based on the dates reviewed.

         Discounted Cash Flow Analysis. The discounted cash flow value analysis
is a widely used valuation methodology but relies on numerous assumptions,
including asset and earnings growth rates, implied price to earnings multiples
and discount rates. The analysis does not purport to be indicative of the actual
values or expected values of First Community's common stock and does not
necessarily represent actual cost savings to be realized by MainSource
Financial.

         Austin estimated the present value of future cash flows assuming First
Community would be acquired and computed the indication of value based on its

                                       20


pro forma earnings stream including synergies. Synergies were estimated at 20
percent of First Community's stand-alone overhead expense. Pro forma overhead
expense reductions in the range of 10 to 30 percent are common in bank mergers.

         The following chart highlights the key assumptions and results of the
discount cash flow analyses:

         Projected cash flows were discounted at rate 13.0 percent. This rate
was selected based on Austin's experience and the expected risk-adjusted rate of
return that an acquirer in First Community would require. Based on the results
from the discounted cash flow analysis, First Community shareholders would
receive an approximate 17.2 percent increase in value with MainSource Financial
as compared to its pro forma discounted cash flow indication of value.

         Pro Forma Merger Analysis. Austin performed a pro forma merger analysis
by combining the projected balance sheets and income statements to determine the
financial impact of the merger on MainSource Financial shareholders. Austin made
certain assumptions regarding the accounting treatment, acquisition adjustments
and cost savings to calculate the financial impact the merger would have on key
performance measures of the pro forma company. The pro forma merger analysis was
based in part on published earnings estimates, Austin's long-term estimated
earnings and growth rates, and estimates of the expected cost savings. Austin
assumed the transaction closed on 12/31/02 and included fully phased-in cost
savings in 2003. The following chart highlights the key results:

         (1)      Includes estimated cost savings.

         Pro Forma Earnings and Book Value. This analysis indicates that the
merger is expected to increase MainSource Financial's stand-alone 2003 earnings
per share by 6.7 percent. MainSource Financial's pro forma tangible book value
per share would equal $10.94 representing a 14.1 percent decrease to its
stand-alone projection of $12.73. At the purchase price of $23.2 million, it
would take approximately six years for MainSource Financial to recover the
tangible book value dilution.

         Additional Limiting Conditions. The opinion expressed by Austin was
based on market, economic and other relevant considerations as they existed and
could be evaluated as of the date of the opinion. Events occurring after the
date of issuance of the opinion, including but not limited to, changes affecting
the securities markets, the results of operations or material changes in the
financial condition of either MainSource Financial or First Community could
materially affect the assumptions used in preparing this opinion.

         First Community has agreed to pay Austin a cash fee of $15,000 for the
issuance of its fairness opinion. None of this fee is contingent upon
shareholder approval or closing of the merger. In addition, First Community has
agreed to indemnify Austin against certain liabilities, including liabilities
under securities laws.

CONDUCT OF BUSINESS IF THE MERGER IS NOT CONSUMMATED

         If the merger is not consummated, First Community will continue its
current operations. For reasons discussed under the caption, "THE MERGER -
Background and Reasons for the Merger," First Community may continue to explore
strategic alternatives, including a business combination or sale of First
Community, if the merger with MainSource Financial is not consummated.

REGULATORY FILINGS AND APPROVALS

         MainSource Financial and First Community have agreed to use their
reasonable best efforts to obtain all regulatory approvals required to
consummate the merger, which include filing applications with the Board of
Governors of the Federal Reserve System and the Indiana Department of Financial
Institutions, AND HAVE MADE THE APPLICABLE REGULATORY FILINGS PRIOR TO THE DATE
OF THIS DOCUMENT. The merger cannot proceed in the absence of these regulatory
approvals. There can be no assurance that these regulatory approvals will be
obtained, and, if obtained, there can be no assurance as to the date of any such
approvals or the absence of any litigation challenging such approvals.

                                       22


MainSource Financial and First Community are not aware of any other material
governmental approvals or actions that are required prior to the parties'
consummation of the merger other than those described above.

                              THE MERGER AGREEMENT

         The description of the merger agreement set forth below is not
complete. For full information, you should read the merger agreement, a copy of
which is attached to this document as Annex A.

TERMS OF THE MERGER

         THE MERGER. The merger agreement contemplates the merger of First
Community with and into a wholly-owned subsidiary of MainSource Financial.
Immediately after the merger becomes effective, the wholly-owned subsidiary of
MainSource Financial will be the surviving corporation, and the separate
existence of First Community will cease.

         EFFECTIVE TIME. As promptly as practicable after the satisfaction or
waiver of the conditions set forth in the merger agreement, the parties will
complete the merger by filing Articles of Merger with the Secretary of State of
Indiana. The merger will be effective upon the filing of the Articles of Merger
or such later date as specified in the Articles of Merger.

         CANCELLATION OF THE COMMON SHARES AND OPTIONS OF FIRST COMMUNITY IN THE
MERGER. If the merger of First Community with the subsidiary of MainSource
Financial closes after the satisfaction or waiver of all of the closing
conditions, the following shall occur:

         (i) each outstanding common share of First Community will be cancelled
and extinguished in consideration and exchange for the right to receive $21.00
in cash from MainSource Financial; and

         (ii) each unexercised option to purchase First Community's common
shares will be canceled and converted into the right to receive in cash $21.00
per share less the exercise price of such option.


EXCHANGE OF CERTIFICATES

         EXCHANGE AGENT. MainSource Bank, Greensburg, Indiana will act as
exchange agent for the exchange of share certificates pursuant to the merger.

         EXCHANGE PROCEDURES. As soon as practicable, but not later than one
business day following the effective time of the merger, MainSource Financial
shall deposit an amount of cash sufficient to make payment of the merger
consideration to each record holder of common shares of First Community and each
holder of outstanding unexercised options of First Community that are converted
into the right to receive cash in the merger. As soon as practicable after the
effective time of the merger, the exchange agent shall mail or make available to
each record holder of common shares or options a notice and letter of
transmittal disclosing the effectiveness of the merger and the procedure for
exchanging each such record holder's common shares, options or promissory notes.
First Community shareholders will be required to follow the instructions and
surrender their certificates representing First Community common shares,
together with the properly executed letter of transmittal, and any other
required documents, to MainSource Bank. Such shareholders will then be entitled

                                       23


to receive $21.00 in cash for each First Community common share held and such
option holders will be entitled to receive $21.00 in cash minus the exercise
price of each unexercised option. No interest will be paid on any merger
consideration.

         DISSENTING SHARES. Any holder of First Community shares who has
properly exercised dissenters' rights shall be entitled to payment for such
shares pursuant to Indiana law. If, in accordance with Indiana law, any holder
of dissenting shares shall forfeit such right to payment of the fair value of
such shares, such shares shall thereupon be deemed to have been converted into
and to have become exchangeable for, as of the effective time of the merger, the
right to receive $21.00 per share.

First Community's common shares and that it has or has timely access to
sufficient funds to perform its obligations under the merger agreement.

CONDUCT OF BUSINESS PENDING THE MERGER

         First Community agreed that until the merger is effective, it will
conduct its business operations in the ordinary and usual course, consistent
with past practice, and will seek to preserve intact its business organization,
keep available the service of its directors, officers and employees, and
preserve its relationships with customers, suppliers and others having business
dealings with it. The merger agreement provides that First Community shall not,
and shall cause its subsidiaries not to, without the prior approval of
MainSource Financial:

         o        issue, sell, grant, dispose of or otherwise encumber any
                  shares of capital stock, other than upon the exercise of stock
                  options or the conversion of convertible debt securities;

         o        purchase any of First Community's common shares;

         o        effect any recapitalization, reclassification, stock dividend,
                  stock split or like change in capitalization;

         o        declare, set aside, make or pay any dividend or other
                  distribution, except for regular quarterly cash dividends not
                  to exceed $0.05 per share;

         o        adopt a plan of complete or partial liquidation, dissolution,
                  merger consolidation, restructuring, recapitalization or other
                  reorganization;

         o        amend its Articles of Incorporation or Bylaws;

         o        acquire or dispose of assets or securities, except in the
                  ordinary course of business;

         o        incur any indebtedness for borrowed money or make any loans or
                  investments other than in the ordinary course of a banking
                  business;

         o        increase the rate of compensation of any of its directors,
                  officers or employees;

         o        pay or agree to pay any pension, retirement allowance,
                  severance or other employee benefit not required by existing
                  benefit plans;

         o        change its method of accounting;

         o        offer any new deposit, loan or investment product or service
                  or modify any of its lending or investment policies;

         o        take any action that would make any of the representations and
                  warranties made by First Community in the merger agreement
                  inaccurate in any material respect at the effective time of
                  the merger; or

         o        take any action that would adversely affect the ability of
                  MainSource Financial to obtain regulatory approval for the
                  merger.

         NO SOLICITATION. The merger agreement provides that First Community
shall not initiate, solicit or encourage inquiries or proposals, furnish any
information or participate in any discussions or negotiations with any person in
connection with any merger, acquisition or consolidation, or any acquisition or
purchase of all or a substantial portion of the assets of or equity interests in
First Community. The merger agreement does not, however, prohibit First
Community from furnishing information to, or entering into discussions,
negotiations or an agreement with any person who makes an unsolicited bona fide
proposal for any transaction described above, or from disclosing to First
Community's shareholders a position with respect to the unsolicited proposal, if
the Board of Directors, after consulting with and being advised by legal
counsel, determines in good faith that such actions are required to fulfill its
fiduciary obligations under the law.

         First Community is not permitted to enter into such other acquisition
proposal except concurrently with the termination of the merger agreement.

ADDITIONAL AGREEMENTS

         ACCESS TO INFORMATION. First Community and its subsidiaries shall
afford MainSource Financial and its representatives reasonable access to its
books, records, properties, personnel and representatives. MainSource Financial
shall hold such information that is non-public in confidence, unless required to
disclose such information by subpoena, civil investigative demand or other
similar process.

         SHAREHOLDERS MEETING. First Community shall duly call, give notice of,
convene and hold a meeting of its shareholders for the purpose of voting on the
approval of the merger. The Board of Directors of First Community will recommend
the approval of the merger to the shareholders unless such a recommendation
would violate Indiana law.

         REASONABLE EFFORTS. MainSource Financial and First Community will use
all reasonable efforts to take all actions necessary to consummate the merger,
including obtaining the approvals or consents by the Board of Governors of the
Federal Reserve System, the Indiana Department of Financial Institutions and any
other governmental agencies as are required.

                                       26


         FINANCIAL STATEMENTS. First Community shall make available to
MainSource Financial copies of:

         o        any monthly or quarterly unaudited consolidated financial
                  statements for periods ended after [September 30, 2002]; and

         o        any audited consolidated financial statements for any year
                  ended after [September 30, 2002].

         EXPENSES. Whether or not the merger is consummated, all costs and
expenses incurred in connection with the merger shall be paid by the party
incurring such expense.

         INDEMNIFICATION. For a period of three (3) years after the effective
time of the merger, MainSource Financial shall indemnify, defend and hold
harmless the officers and directors of First Community [and its subsidiaries]
against claims, losses or damages, including expenses in advance of final
disposition, arising out of or based on the merger to the full extent permitted

         o        by mutual agreement of MainSource Financial and First

         o        by the Board of Directors of MainSource Financial or First

                           is due to either party's material breach of the
                           merger agreement, the Board of Directors of such
                           breaching party shall not have the right to terminate

                           condition and such breach cannot be or has not been
                           cured within thirty (30)days, provided that the

         o        by the Board of Directors of First Community or MainSource
                  Financial if any event has occurred or circumstance has arisen

                  the conditions that such party is subject to under the merger
                  agreement as of the date of such determination; or

                  then in breach of the merger agreement and First Community has
                  complied with its obligations under the merger agreement in
                  connection with its receipt of the alterative merger proposal.

         BREAK-UP FEE. First Community is required to pay a break-up fee of

                  MainSource Financial because the merger is not consummated on
                  or before June 30, 2003, if at the time of termination First
                  Community is in material breach of any of its representations,
                  warranties or covenants under the merger agreement that would

                  cured within 30 days;

         o        the merger agreement is terminated because a court or
                  governmental entity has issued an order or taken action

                  termination First Community is in material breach of any of
                  its representations, warranties or covenants under the merger
                  agreement that would give rise to a failure of condition and

         o        the merger agreement is terminated by MainSource Financial

                  not capable of being satisfied; or

         o        the merger agreement is terminated by First Community because
                  it has approved and entered into a definitive agreement of an
                  alternative merger transaction.

INTERESTS OF DIRECTORS AND EXECUTIVE OFFICERS

         TREATMENT OF STOCK OPTIONS. At the time the merger is effective, each
outstanding option to purchase First Community common shares will be cancelled
and extinguished, and the holders of such stock options will be entitled to
receive cash from MainSource Financial in the amount of the difference between
(a) the product of (i) the difference between $21.00 and the exercise price per
share of such stock option, multiplied by (ii) the number of common shares

                                       30


subject to such stock option, less (b) applicable federal and state tax
withholding obligations of the holder of such stock option.

         As of _________, 2003, options to purchase 34,700 shares were
outstanding, of which the directors and executive officers of First Community
held options to purchase a total of ______ shares. All of the options issued by
First Community had exercise prices less than $21.00 per share and therefore are
expected to receive option cancellation payments.

         Each holder of a stock option will be required to execute an option
cancellation agreement in order to receive payment for the option.

         TERMINATION AGREEMENTS. Three (3) employees of a subsidiary of First
Community, Albert R. Jackson, III, Keith Lindauer and Dean Jackson, are parties
to Termination Agreements with First Community Bank & Trust dated as of July 28,
1999. Each of the Termination Agreements provides that in the event of a change
in control, which includes the acquisition by another company of 100% of the
voting stock of First Community, and in the event the employment of the employee
is terminated for any reason other than good cause within 180 days of the change
in control, the employee is entitled to receive a lump sum equal to 299% of his
average total compensation for the prior three (3) years. At the effective time
of the merger, and as condition to each party's obligation to close the merger,
each employee shall execute a waiver of his rights under the Termination
Agreements and those agreements shall be terminated. In consideration for this
waiver and termination, MainSource Financial and each employee shall execute
employment agreements effective at the time of the merger and continuing until
December 31, 2004, and MainSource Financial shall pay each employee a lump sum
cash payment of $240,000 for Albert R. Jackson, III, $175,000 for Keith Lindauer
and $144,000 for Dean Jackson. Upon execution of the employment agreements, each
employee shall also receive a $25,000 signing bonus.

         DEFERRED COMPENSATION AGREEMENTS. Each member of the Board of Directors
of First Community Bank & Trust, including Albert R. Jackson, Jr., Merrill M.
Wesemann, Frank D. Neese and Roy M. Umbarger, and Albert R. Jackson, III, in his
capacity as an executive officer of First Community Bank & Trust, are parties to
Deferred Compensation Agreements with First Community Bank & Trust. These
agreements permit the deferral by the director or officer of a portion of the
compensation received by such director or officer into an account maintained by
First Community Bank & Trust with an annual interest rate as determined by the
Board of Directors of First Community Bank & Trust. Pursuant to the merger
agreement, all of the Deferred Compensation Agreements will terminate effective
as of the closing of the merger and all amounts accrued thereunder will be paid
to such persons.

         SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN. Certain directors and executive
officers of First Community Bank & Trust (8 persons) are participants in the
First Community Bank & Trust Supplemental Executive Retirement Plan ("SERP").
Under the SERP, a participant who has obtained 72 years of age, is serving as a
director or employee at that time, and has completed at least three years of
participation in the SERP is entitled to received annual payments for the rest
of his life (or a minimum of ten years) equal to 100% of the average of the
director fees such person received or would have received had such person been a
director each year for the most recent three-year period. A participant who has
completed at least five years of employment or service as a director with First
Community may elect early retirement on or after attaining age 65. A

                                       31


participant electing early retirement is entitled to receive the actuarial
equivalent (present value) of the normal retirement benefit described above.

         Upon a change in control, the definition of which includes the merger,
each participant in the SERP is deemed to have remained in the employ of First
Community Bank & Trust until his normal retirement age (72 years old), and may
commence receipt of the actuarial equivalent of his normal retirement benefit at
any time after the termination of his employment or service on the Board.
Pursuant to the merger agreement, the participants in the SERP shall execute and
deliver the following at the closing at the merger:

         o        each of Albert R. Jackson, III, Keith Lindauer and Dean
                  Jackson shall execute a waiver of their rights upon a change
                  in control and a consent to terminate the SERP;

         o        Don Goeb and Roy M. Umbarger shall each execute a consent to
                  terminate the SERP and accept, as a change in control benefit,
                  $107,212 for Mr. Goeb and $107,212 for Mr. Umbarger; and

         o        each of Albert R. Jackson, Jr., Merrill M. Wesemann and Frank
                  D. Neese shall elect early retirement from the Board of
                  Directors of First Community Bank & Trust and shall execute a
                  waiver of their rights upon a change in control.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

         The following is a summary of material federal income tax consequences
of the merger to First Community shareholders. It is assumed for purposes of
this discussion that the common shares are held as "capital assets" within the
meaning of Section 1221 of the Internal Revenue Code. The tax consequences to
each shareholder will depend in part upon such shareholder's particular
situation. Generally, shareholders will recognize gain, if any, up to the amount
of cash received, depending upon such shareholder's basis in the First Community
common shares that such shareholder owns. Similarly, if a shareholder is a
dissenting shareholder who receives cash in payment for such dissenting
shareholder's common shares, such shareholder will recognize gain, if any, up to
the amount of cash such dissenting shareholder receives, based upon such
dissenting shareholder's basis in the First Community common shares that such
dissenting shareholder owns.

         Special tax consequences not described in this document may be
applicable to particular classes of taxpayers, such as financial institutions,
insurance companies, tax-exempt organizations, broker-dealers, traders in
securities that elect to mark to market, persons that hold common shares as part
of a straddle or conversion transaction, persons who are not citizens or
residents of the United States and shareholders who acquired their common shares
through the exercise of an employee stock option or otherwise as compensation.
The foregoing disclosure is for general information only and is based upon the
Internal Revenue Code, its legislative history, existing and proposed
regulations thereunder, published rulings and decisions, all as currently in
effect as of the date hereof, and all of which are subject to change, possibly
with retroactive effect. No ruling has been or will be sought from the Internal
Revenue Service on the United States federal income tax consequences of the
merger. Tax consequences under state, local and foreign laws are not addressed
in this document. All shareholders should consult with their own tax advisors as
to the particular tax consequences of the merger, including the

                                       32


applicability and effect of the alternative minimum tax and any state, local or
foreign income and other tax laws and of changes in such tax laws.
