                               December   , 1997
 
To Our Shareholders:
 
    A special meeting (the "First Citizens Special Meeting") of shareholders of
First Citizens Banc Corp, a bank holding company organized and existing under
the laws of the State of Ohio ("First Citizens"), has been scheduled for January
  , 1998 at 2:00 p.m. at The Citizens Banking Company, 100 East Water Street,
Sandusky, Ohio. The accompanying Notice of the First Citizens Special Meeting,
Proxy Statement/Prospectus and Proxy Card set forth the formal business to be
transacted at the First Citizens Special Meeting. I encourage you to review
these materials and to attend the First Citizens Special Meeting.
 
    At the First Citizens Special Meeting, holders of First Citizens common
shares, without par value, are being asked to consider and vote upon a proposal
(the "Proposal") to adopt the Agreement and Plan of Reorganization dated July 3,
1997, as amended November 25, 1997 and November 26, 1997, respectively, by and
between First Citizens and The Farmers State Bank of New Washington, Ohio, a
commercial bank organized and existing under the laws of the State of Ohio
("Farmers") (as amended, the "Reorganization Agreement"), and the Merger
Agreement dated November 26, 1997 by and among First Citizens, Farmers and
Farmers Interim Bank, a wholly-owned subsidiary of First Citizens organized and
existing under the laws of the State of Ohio for the limited purpose of
effecting the Merger (as hereinafter defined) (the "Merger Agreement"); and to
approve the transactions contemplated thereby, including the merger (the
"Merger") of Farmers Interim Bank with and into Farmers. In the Merger, each
outstanding common share of Farmers, par value $20.00 per share, will be
converted into the right to receive 6.06 common shares, without par value, of
First Citizens, upon the terms and subject to the conditions set forth in the
Reorganization Agreement and the Merger Agreement, as described in the
accompanying Proxy Statement/Prospectus (with cash paid in lieu of fractional
shares).
 
    Consummation of the Merger is subject to certain conditions, including, but
not limited to, obtaining the requisite vote of the shareholders of Farmers and
First Citizens and the approval of the Merger by various regulatory agencies.
 
    THE FIRST CITIZENS BOARD OF DIRECTORS HAS UNANIMOUSLY CONCLUDED THAT THE
MERGER IS FAIR TO AND IN THE BEST INTERESTS OF THE FIRST CITIZENS SHAREHOLDERS
AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL.  First Citizens'
financial advisor, McDonald & Company Securities, Inc., has rendered an opinion
dated July 3, 1997 and updated to the date hereof to the First Citizens Board of
Directors to the effect that, as of the date hereof and based upon and subject
to certain matters stated in such opinion, the exchange ratio set forth in the
Merger Agreement is fair to the shareholders of First Citizens from a financial
point of view.
 
    If the accompanying Proxy Card is executed properly and returned to First
Citizens in time to be voted at the First Citizens Special Meeting, the shares
represented thereby will be voted in accordance with the instructions marked
thereon. Executed but unmarked proxies will be voted FOR approval of the
Proposal. The presence of a shareholder at the First Citizens Special Meeting
will not automatically revoke such shareholder's proxy. A First Citizens
shareholder may, however, revoke a proxy at any time prior to its exercise by
filing a written notice of revocation with or delivering a duly executed proxy
bearing a later date to Donna J. Dalferro, Vice President and Secretary, First
Citizens Banc Corp, 100 East Water Street, Sandusky, Ohio 44870 or by attending
the First Citizens Special Meeting and advising the Secretary of the
shareholder's intent to vote the shares.
 
    Approval of the Proposal requires the affirmative vote of a majority of the
outstanding common shares of First Citizens. Accordingly, it is very important
that your shares be represented at the First Citizens Special Meeting. I urge
you to vote FOR the Proposal and to sign, date and return the accompanying Proxy
Card as soon as possible, even if you plan to attend the First Citizens Special
Meeting. This procedure will not prevent you from voting in person, but will
ensure that your vote is counted if you are unable to attend.
 
                                        Very truly yours,
 
                                        David A. Voight

                             YOUR VOTE IS IMPORTANT
 WE ENCOURAGE YOU TO SIGN, DATE AND PROMPTLY RETURN YOUR PROXY IN THE ENCLOSED
                              ENVELOPE REGARDLESS
       OF WHETHER YOU PLAN TO ATTEND THE FIRST CITIZENS SPECIAL MEETING.

    If the accompanying Proxy Card is executed properly and returned to Farmers

Executed but unmarked proxies will be voted FOR approval of the Proposal. The

shares.
 
    Approval of the Proposal requires the affirmative vote of the holders of
two-thirds of the outstanding common shares of Farmers. Accordingly, it is very
important that your shares be represented at the Farmers Special Meeting. I urge
you to vote FOR the Proposal and to sign, date and return the accompanying Proxy
Card as soon as possible, even if you plan to attend the Farmers Special

BACKGROUND AND REASONS FOR
THE MERGER.................  First Citizens. First Citizens' Board of Directors
                             has concluded that the Merger is in the best
                             interests of the First Citizens shareholders
                             because, among other things, (i) the Merger will
                             facilitate the logical expansion of First Citizens'
                             business into three complementary markets
                             (Crawford, Union and Marion Counties), (ii) Farmers
                             has the leading market share in Crawford County,
                             (iii) First Citizens has identified certain
                             strategic initiatives which may enhance Farmers'
                             customer service and financial performance, (iv)
                             the Merger will potentially improve the trading
                             market as well as increase the liquidity of the
                             Citizens Common Shares due to the issuance of
                             additional First Citizens Common Shares, and (v)
                             the Merger will potentially provide for an improved
                             earnings growth rate in the future. First Citizens'
                             Board of Directors did not assign any particular
                             weight to each of the factors considered. See
                             "PROPOSED MERGER -- First Citizens Background and
                             Reasons for the Merger."
 
                             Farmers. Farmers' Board of Directors has concluded
                             that the Merger is in the best interests of Farmers
                             and its shareholders based on, among other things,
                             (i) the business earnings and potential for future
                             growth and prospects of Farmers and First Citizens,
                             (ii) the potential operational and managerial
                             benefits that will be derived from the Merger,
                             (iii) the consideration to be received by Farmers
                             shareholders in the Merger in relation to the book
                             value and earnings of Farmers, (iv) the prices paid
                             for Farmers' Common Shares in the limited trades
                             known to Farmers' management, (v) the prices paid
                             in similar merger transactions, (vi) the increased
                             dividend rate; (vii) the tax-free nature of the
                             stock-for-stock exchange; and (viii) the
                             comparatively greater liquidity that Farmers'
                             shareholders might enjoy by being shareholders of a
                             larger institution.

                             Farmers' Board of Directors also considered its
                             belief that First Citizens shares a community
                             banking philosophy that will benefit the employees,
                             depositors and customers of Farmers and the
                             communities it serves and that the Merger will
                             allow Farmers to offer a diversity of products and
                             services to its customers. Farmers' Board of
                             Directors did not assign any particular weight to
                             each of the factors considered. See "PROPOSED
                             MERGER -- Farmers Background and Reasons for the
                             Merger."

                             see "PROPOSED MERGER -- Fairness Opinion of Austin
                             Associates." The opinion of Austin & Associates is
                             attached as Appendix E to this Proxy
                             Statement/Prospectus. Farmers shareholders are
                             urged to read such opinion in its entirety for a
                             description of the procedures followed and matters
                             considered in connection therewith.
 
INTEREST OF MANAGEMENT IN
THE MERGER.................  The Reorganization Agreement provides that First
                             Citizens will offer the existing full-time
                             employees of Farmers the opportunity to continue as
                             employees of Farmers, as the surviving bank
                             ("Surviving Bank") following the Merger. The
                             Reorganization Agreement further provides, however,
                             that such commitment shall not be deemed to be a
                             contract of employment or construed to give
                             Farmers' employees any rights other than as
                             employees at will under Ohio law and Farmers'
                             employees shall not be deemed to be third-party
                             beneficiaries of such commitment. See "PROPOSED
                             MERGER -- Operations of Farmers After the Merger
                             and "Interest of Management in the Merger."

DISSENTERS' RIGHTS.........  Holders of Farmers Common Shares may exercise their
                             right to become dissenting shareholders to the
                             extent, and in strict compliance with the
                             procedure, specified in Sections 1115.19 and

FEDERAL INCOME TAX
  CONSEQUENCES OF THE
  MERGER...................  It is intended that the Merger will be treated as a
                             reorganization within the meaning of Section 368(a)
                             of the Internal Revenue Code of 1986, as amended,
                             and that, accordingly, for federal income tax
                             purposes no gain or loss will be recognized by
                             Farmers or First Citizens as a result of the
                             Merger. The obligation of Farmers and First
                             Citizens to consummate the Merger is conditioned on
                             the receipt by Farmers of an opinion of its
                             counsel, Werner & Blank Co., L.P.A., dated as of
                             the closing date of the Merger, substantially to
                             the effect that (i) the Merger will constitute a
                             tax free reorganization, (ii) no gain or loss will
                             be recognized by Farmers as a consequence of the
                             Merger, (iii) no gain or loss will be recognized by
                             the Farmers shareholders upon the receipt solely of
                             First Citizens Common Shares in exchange for
                             Farmers Common Shares, except with respect to any
                             cash received in lieu of a fractional share
                             interest in First Citizens Common Shares, (iv) the
                             federal income tax basis of the First Citizens
                             Common Shares received by the Farmers shareholders
                             for their Farmers Common Shares will be the same as
                             the federal income tax basis of the Farmers Common
                             Shares surrendered in exchange therefor, and (v)
                             the holding period for the First Citizens Common
                             Shares received by each Farmers Shareholders in
                             exchange for Farmers Common Shares will include the
                             period for which the Farmers Common Shares
                             exchanged therefor were held, provided that the
                             exchanged Farmers Common Shares were held as
                             capital assets by such Farmers shareholder. Farmers
                             shareholders who exercise dissenters' rights and
                             receive cash for their Farmers Common Shares will
                             be treated as having received a distribution in
                             redemption of their shares which will result in
                             such shareholders receiving income for federal
                             income tax purposes.
 
                             All Farmers shareholders should read carefully the
                             description under "PROPOSED MERGER -- Federal
                             Income Tax Consequences of the Merger," and should
                             consult their own tax advisors concerning these
                             matters.
 
CONDITIONS; AMENDMENTS;
  TERMINATION..............  Completion of the Merger is contingent upon
                             approval of the Reorganization Agreement and the
                             Merger Agreement by the respective shareholders of
                             Farmers and First Citizens and certain regulatory
                             authorities and upon certain other conditions
                             described in this Proxy Statement/Prospectus.
                             Neither the Reorganization Agreement nor the Merger
                             Agreement may be

                             amended except by a written agreement executed by
                             the parties. Both the Reorganization Agreement and
                             the Merger Agreement may be terminated and the
                             Merger abandoned by mutual agreement of First
                             Citizens and Farmers, or by either First Citizens
                             or Farmers in the event of failure to satisfy
                             certain conditions, or if the Merger has not been
                             consummated by February 28, 1998. In addition, the
                             Merger Agreement may be terminated (i) by Farmers
                             or Farmers Interim Bank if, prior to the
                             consummation of the Merger, there has been a final
                             judicial determination that any material provision
                             of the Merger Agreement is illegal, invalid or
                             unenforceable; and (ii) by Farmers if the market
                             price for the First Citizens Common Shares falls
                             below a certain level.
 
                             See "PROPOSED MERGER -- Other Provisions of the
                             Reorganization Agreement and the Merger Agreement."
 
MANAGEMENT AFTER THE
MERGER.....................  Upon completion of the Merger, Farmers Interim Bank
                             will be merged with and into Farmers, with Farmers
                             as the Surviving Bank. At the Effective Time, the
                             Board of Directors of the Surviving Bank shall
                             consist of all of the persons who were directors of
                             Farmers immediately prior to the Effective Time,
                             plus two nominees of First Citizens. See "PROPOSED
                             MERGER -- Operations of Farmers After the Merger."
 
                   COMPARATIVE RIGHTS OF FARMERS SHAREHOLDERS
 
     The rights of shareholders of First Citizens and shareholders of Farmers,
while similar in many respects, also differ in some respects. For a description
of the relative rights of the holders of First Citizens Common Shares and
Farmers Common Shares, see "COMPARATIVE RIGHTS OF FARMERS SHAREHOLDERS." First
Citizens' Articles of Incorporation include provisions governing certain
business combinations involving First Citizens. For a description of this
provision, see "DESCRIPTION OF FIRST CITIZENS COMMON SHARES -- Provisions
Relating to Business Combinations."

                    PRO FORMA SELECTED FINANCIAL INFORMATION
 
     The table below sets forth selected pro forma financial information for
First Citizens and Farmers combined as of and for the nine months ended
September 30, 1997 and 1996, and as of and for the years ended December 31,
1996, 1995 and 1994. This information is derived from and should be read in
conjunction with the historical financial statements of First Citizens and
Farmers that are incorporated by reference or appear elsewhere in this Proxy
Statement/Prospectus, and with the pro forma condensed consolidated financial
statements of First Citizens, which give effect to the Merger and which appear
in this Proxy Statement/Prospectus under the caption "PRO FORMA FINANCIAL
INFORMATION." The pro forma condensed consolidated financial information has
been prepared based on the use of the "pooling-of-interests" method of
accounting, assuming that 1,212,000 First Citizens Common Shares will be issued
and that no Farmers shareholders will dissent. This information will vary if any
Farmers shareholders exercise dissenter rights with respect to the Merger. The
historical financial information of First Citizens and Farmers has been combined
for each period presented. For a discussion of the pooling-of-interests method
of accounting and the condition to First Citizens' and Farmers' obligations
under the Reorganization Agreement that the Merger qualify for the
pooling-of-interests method of accounting, see "PROPOSED MERGER -- Accounting
Treatment" and "Other Provisions of the Reorganization Agreement and the Merger
Agreement."

     The following table sets forth First Citizens' and Farmers' historical per
share data and pro forma combined per share data. The information is based on
the historical financial statements of First Citizens and Farmers. The pro forma
data do not purport to be indicative of the results of future operations or the
actual results that would have occurred had the Merger been consummated at the
beginning of the periods presented. The pro forma data give effect to the Merger
and are based on numerous assumptions and estimates. The pro forma data are
included as required by the rules of the Commission and are provided for
comparative purposes only. The pro forma combined per share data and Farmers
equivalent per share data are prepared assuming 1,212,000 First Citizens Common
Shares will be issued based on the Exchange Ratio. See "PROPOSED

     First Citizens Common Shares are traded on the Nasdaq National Bulletin
Board under the symbol "FCZA." Farmers Common Shares are not traded in any
established market. The information presented in the following table reflects
the last reported sale price for First Citizens on July 2, 1997, the last
trading day preceding execution of the Reorganization Agreement; the sale price
for Farmers Common shares in the most recent transaction occurring prior to July
3, 1997, of which Farmers' management is aware; and the equivalent per share
basis of Farmers. The equivalent per share basis has been calculated by
multiplying the last reported sale price on such date by the Exchange Ratio. The
market value of the consideration to be received by the Farmers Shareholders
will depend on the market value of a share of First Citizens Common Shares at
such time. No assurance can be given as to what the market price of First
Citizens Common Shares will be if and when the Merger is consummated. See also

           INFORMATION CONCERNING THE FIRST CITIZENS SPECIAL MEETING
 
GENERAL
 
     This Proxy Statement/Prospectus is being furnished to holders of First
Citizens Common Shares as part of the solicitation of proxies by the First
Citizens Board of Directors for use at the First Citizens Special Meeting to be
held on January   , 1998 at 2:00 p.m., at The Citizens Banking Company, 100 East
Water Street, Sandusky, Ohio 44870, including any adjournments or reschedulings
thereof. This Proxy Statement/Prospectus and the accompanying Proxy Card are
first being mailed to shareholders of First Citizens on or about December   ,
1997.
 
     The purpose of the First Citizens Special Meeting is to consider and vote
upon the Proposal to adopt the Reorganization Agreement and the Merger Agreement
and to approve the transactions contemplated thereby, including the Merger. No
other business will be transacted at the First Citizens Special Meeting other
than possible adjournments or reschedulings thereof.
 
     The Merger is subject to a number of conditions, including the receipt of
required regulatory and shareholder approvals. (See "PROPOSED
MERGER -- "Regulatory Approvals" and "Other Provisions of the Reorganization
Agreement and the Merger Agreement.")
 
SOLICITATION, VOTING AND REVOCABILITY OF PROXIES
 
     The First Citizens Board of Directors has fixed the close of business on
            , 1997 (the "First Citizens Record Date") as the record date for the
determination of the shareholders of First Citizens entitled to notice of and to
vote at the First Citizens Special Meeting. Only holders of record of First
Citizens Common Shares at the close of business on the First Citizens Record
Date will be entitled to vote on each matter properly
 
                                        9
<PAGE>   23
 
presented at the First Citizens Special Meeting. On the First Citizens Record
Date, 3,051,504 First Citizens Common Shares were issued and outstanding. Votes
may be cast in person or by proxy, and each First Citizens Common Share entitles
its holder to one vote. Pursuant to the First Citizens Code of Regulations and
in accordance with the Ohio Revised Code ("ORC"), the presence of the holders of
a majority of the First Citizens Common Shares issued and outstanding, in person
or by proxy, and entitled to vote at the First Citizens Special Meeting is
required for and shall constitute a quorum for the transaction of business at
the First Citizens Special Meeting. For such purpose, abstentions and broker
non-votes will be counted in establishing the quorum. A majority of the First
Citizens Common Shares present at the First Citizens Special Meeting, in person
or by proxy, whether or not constituting a quorum, may vote to, or the First
Citizens Board in its discretion may, adjourn the First Citizens Special Meeting
from time to time without further notice, including for the purpose of
soliciting additional proxies. Under the First Citizens Articles of
Incorporation and the ORC, the affirmative vote of the holders of at least a
majority of the total number of outstanding First Citizens Common Shares
entitled to vote at the First Citizens Special Meeting is required to approve
the Proposal. An abstention and a broker non-vote would thus have the same
effect as a vote against the Proposal.
 
     Only shareholders of record on the First Citizens Record Date are eligible
to give their proxies. Therefore, shareholders owning shares held in the name of
a brokerage firm, bank, or other institution should sign, date and return their
proxy cards to such brokerage firm, bank or other institution in the envelope
provided by that firm. In addition, under the rules of the New York Stock
Exchange, brokers who hold shares in street name for customers who are the
beneficial owners of such shares are prohibited from giving a proxy to vote
shares held for such customers on the approval of the Proposal without specific
instructions from such customers. Given that the First Citizens Articles of
Incorporation require the affirmative vote of the holders of a majority of the
outstanding First Citizens Common Shares entitled to vote at the First Citizens
Special Meeting in order to approve the Proposal, the failure of such customers
to provide specific instructions with respect to their First Citizens Common
Shares to their broker will have the effect of a vote against the approval of
the Proposal. Failure to return a properly executed proxy card or to vote at the
First Citizens Special Meeting will have the same effect as a vote against the
Proposal.
 
     Proxies in the accompanying form which are properly executed and returned
to First Citizens will be voted at the First Citizens Special Meeting in
accordance with the shareholders' instructions contained in such proxies and, at
the discretion of the Proxy Committee, on such other matters as may properly
come before the meeting. If a shareholder returns a proxy card that is signed,
dated and not marked, that shareholder will be deemed to have voted FOR the
Proposal. An executed proxy may be revoked at any time prior to its exercise by
submitting another proxy with a later date, by appearing in person at the First
Citizens Special Meeting and advising the Secretary of the shareholder's intent
to vote the shares or by sending a written, signed and dated revocation which
clearly identifies the proxy being revoked to the principal executive offices of
First Citizens at 100 East Water Street, Sandusky, Ohio 44870, Attention: Donna
J. Dalferro, Vice President and Secretary. A revocation may be in any written
form validly signed by the record holder as long as it clearly states that the
proxy previously given is no longer effective. In addition, shareholders whose
First Citizens Common Shares are not registered in their own name will need
additional documentation from the record holder of such shares to vote in person
at the First Citizens Special Meeting.
 
     Proxies may be solicited by mail, telephone, telegraph, telex, telecopier
and advertisement and in person. Solicitation may be made in the same manner by
directors, officers and other representatives of First Citizens who will not be
specially compensated for such activities, but who may be reimbursed for
reasonable out-of-pocket expenses in connection with such solicitation.
 
     Banks, brokerage houses and other custodians, nominees and fiduciaries will
be requested to forward the solicitation materials to the beneficial owners of
First Citizens Common Shares for which they hold of record, and First Citizens
will reimburse them for their reasonable out-of-pocket expenses.
 
     The expenses related to the proxy solicitation for the First Citizens
Special Meeting will be borne by First Citizens, except that the cost of
preparing and mailing this Proxy Statement/Prospectus will be shared by First
Citizens and Farmers.

               INFORMATION CONCERNING THE FARMERS SPECIAL MEETING
 
GENERAL
 
     This Proxy Statement/Prospectus is being furnished to holders of Farmers
Common Shares as part of the solicitation of proxies by the Farmers Board of
Directors for use at the Farmers Special Meeting to be held on January   , 1998
at 2:00 p.m., at 102 South Kibler Street, New Washington, Ohio, including any
adjournments or reschedulings thereof. This Proxy Statement/Prospectus and the
accompanying Proxy Card are first being mailed to shareholders of Farmers on or
about December   , 1997.
 
     The purpose of the Farmers Special Meeting is to consider and vote upon the
Proposal to adopt the Reorganization Agreement and the Merger Agreement and to
approve the transactions contemplated thereby, including the Merger. No other
business will be transacted at the Farmers Special Meeting other than possible
adjournments or reschedulings thereof.
 
     The Merger is subject to a number of conditions, including the receipt of
required regulatory and shareholder approvals. (See "PROPOSED
MERGER -- "Regulatory Approvals" and "Other Provisions of the Reorganization
Agreement and the Merger Agreement.")
 
SOLICITATION, VOTING AND REVOCABILITY OF PROXIES
 
     The Farmers Board has fixed the close of business on             , 1997
(the "Farmers Record Date") as the record date for the determination of the
shareholders of Farmers entitled to notice of and to vote at the Farmers Special
Meeting. Only holders of record of Farmers Common Shares at the close of
business on the Farmers Record Date will be entitled to vote on each matter
properly presented at the Farmers Special Meeting. On the Farmers Record Date,
200,000 Farmers Common Shares were issued and outstanding. Votes may be cast in
person or by proxy, and each Farmers Common Share entitles its holder to one
vote. Pursuant to the ORC, the shareholders of Farmers present, in person or by
proxy, shall constitute a quorum for the transaction of business at the Farmers
Special Meeting. A majority of the Farmers Common Shares present at the Farmers
Special Meeting, in person or by proxy, may vote to adjourn the Farmers Special
Meeting from time to time without further notice, including for the purpose of
soliciting additional proxies. Under the ORC, the affirmative vote of the
holders of at least two-thirds of the total number of outstanding Farmers Common
Shares entitled to vote at the Farmers Special Meeting is required to approve
the Proposal. An abstention and a broker non-vote would thus have the same
effect as a vote against the Proposal.
 
     Only shareholders of record on the Farmers Record Date are eligible to give
their proxies. Therefore, shareholders owning shares held in the name of a
brokerage firm, bank, or other institution should sign, date and return their
proxy cards to such brokerage firm, bank or other institution in the envelope
provided by that firm. In addition, under the rules of the New York Stock
Exchange, brokers who hold shares in street name for customers who are the
beneficial owners of such shares are prohibited from giving a proxy to vote
shares held for such customers on the approval of the Proposal without specific
instructions from such customers. Given that the ORC requires the affirmative
vote of the holders of two-thirds of the outstanding Farmers Common Shares
entitled to vote at the Farmers Special Meeting in order to approve the
Proposal, the failure of such customers to provide specific instructions with
respect to their Farmers Common Shares to their broker will have the effect of a
vote against the approval of the Proposal. Failure to return a properly executed
proxy card or to vote at the Farmers Special Meeting will have the same effect
as a vote against the Proposal.
 
     Proxies in the accompanying form which are properly executed and returned
to Farmers will be voted at the Farmers Special Meeting in accordance with the
shareholders' instructions contained in such proxies and, at the discretion of
the Proxy Committee, on such other matters as may properly come before the
meeting. If a shareholder returns a proxy card that is signed, dated and not
marked, that shareholder will be deemed to have
 
                                       11

voted for the Proposal. An executed proxy may be revoked at any time prior to
its exercise by submitting another proxy with a later date, by appearing in
person at the Farmers Special Meeting and advising the Secretary of the
shareholder's intent to vote the shares or by sending a written, signed and
dated revocation which clearly identifies the proxy being revoked to the
principal executive offices of Farmers at 102 South Kibler Street, New
Washington, Ohio 44854-9401, Attention: Wanda J. White, Secretary. A revocation
may be in any written form validly signed by the record holder as long as it
clearly states that the proxy previously given is no longer effective. In
addition, shareholders whose Farmers Common Shares are not registered in their
own name will need additional documentation from the record holder of such
shares to vote in person at the Farmers Special Meeting.
 
     Proxies may be solicited by mail, telephone, telegraph, telex, telecopier
and advertisement and in person. Solicitation may be made in the same manner by
directors, officers and other representatives of Farmers who will not be
specially compensated for such activities, but who may be reimbursed for
reasonable out-of-pocket expenses in connection with such solicitation.
 
     Banks, brokerage houses and other custodians, nominees and fiduciaries will
be requested to forward the solicitation materials to the beneficial owners of
Farmers Common Shares for which they hold of record, and Farmers will reimburse
them for their reasonable out-of-pocket expenses.
 
     The expenses related to the proxy solicitation for the Farmers Special
Meeting will be borne by Farmers, except that the cost of preparing and mailing
this Proxy Statement/Prospectus will be shared by Farmers and First Citizens.
 
     The directors and executive officers of Farmers and their affiliates own,
as of the Farmers Record Date, 64,332 Farmers Common Shares representing 32.18%
of the total number of outstanding shares of Farmers Common Shares at such date.
 
                                PROPOSED MERGER
 
     The following description of certain aspects of the Merger does not purport
to be complete and is qualified in its entirety by reference to the
Reorganization Agreement and the Merger Agreement which are set forth in
Appendices A and B, respectively, attached to and incorporated by reference in
this Proxy Statement/Prospectus. All shareholders are urged to read the
Reorganization Agreement and the Merger Agreement in their entirety.
 
FIRST CITIZENS BACKGROUND AND REASONS FOR THE MERGER
 
  Background of the Merger
 
     On or about March 12, 1997, the management of First Citizens was approached
by Austin Associates as to the level of interest First Citizens might have in an
acquisition of Farmers. Management brought this inquiry to the attention of the
Board of Directors of First Citizens. Because Farmers was within the size and
geographic location initially set in First Citizens' planning sessions, the
First Citizens Board directed management to obtain the package of information
from Austin Associates, solicit input from McDonald & Company and prepare a
presentation to the Board on the viability of such a merger.
 
     During the month of May, 1997, First Citizens conducted its initial due
diligence investigation of Farmers. On June 6, 1997, First Citizens submitted a
final proposal to Farmers regarding the proposed acquisition.
 
     During the last several weeks of June, 1997, First Citizens and Farmers and
their respective representatives negotiated the financial and other terms of the
Reorganization Agreement on an "arm's length" basis. First Citizens and Farmers
entered into the Reorganization Agreement on July 3, 1997.
 
     The Reorganization Agreement was amended on November 25, 1997 to extend the
deadline for consummation of the Merger from February 1, 1998 to February 28,
1998. The Reorganization Agreement was amended again on November 26, 1997 to
remove certain time constraints relating to the consummation of the Merger and
reduce the Exchange Ratio from 6.5 to 6.06. Each such amendment was approved in
advance by the respective
 
                                       12
<PAGE>   26
 
Boards of First Citizens and Farmers. The Merger Agreement was executed by
Farmers, First Citizens and Farmers Interim Bank on November 26, 1997.
 
  Reasons for the Merger
 
     In reaching the determination that the Merger is fair to, and in the best
interests of, First Citizens' shareholders, the First Citizens Board consulted
with First Citizens' management, as well as its financial and legal advisors,
and considered a number of factors, including, without limitation, the
following, which include all of the material factors considered:
 
          (i) the Merger will facilitate the logical expansion of First
     Citizens' business into three complementary markets in Ohio (Crawford,
     Union and Marion Counties);
 
          (ii) Farmers has the leading market share in Crawford County, with
     approximately 17.1% of total deposits in the Crawford County market;
 
          (iii) First Citizens believes it will have an opportunity to enhance
     Farmers' net interest margin through an increase in Farmers' loan volume;
 
          (iv) First Citizens believes it will be able to improve Farmers'
     noninterest revenues through the addition of trust, securities brokerage,
     automated teller machines and expanded demand deposit products which are
     currently not offered to Farmers' customers;
 
          (v) the Merger will potentially improve the trading market as well as
     increase the liquidity of the First Citizens Common Shares due to the
     issuance of additional First Citizens Common Shares; and
 
          (vi) the Merger will potentially provide for an improved earnings
     growth rate in the future.
 
     The First Citizens Board considered many different factors in its
evaluation and did not believe it was practical to, and did not quantify or
otherwise assign relative weights to, the individual factors considered in
reaching its determination.
 
RECOMMENDATION OF THE FIRST CITIZENS BOARD OF DIRECTORS
 
     IN VIEW OF ALL THE CONSIDERATIONS DESCRIBED ABOVE, THE BOARD OF DIRECTORS
OF FIRST CITIZENS UNANIMOUSLY CONCLUDED THAT THE MERGER IS IN THE BEST INTERESTS
OF AND IS FAIR TO THE FIRST CITIZENS SHAREHOLDERS AND RECOMMENDS THAT FIRST
CITIZENS SHAREHOLDERS VOTE FOR THE MERGER.
 
FARMERS BACKGROUND AND REASONS FOR THE MERGER
 
  Background of the Merger
 
     On October 11, 1996, the Board of Directors of Farmers retained Austin
Associates to assist in a strategic planning process. The process was intended
to provide the Board of Directors with information regarding options and
alternatives available to Farmers as it contemplated its future direction.
Included in the Austin Associates project were an analysis of the value of
Farmers, composition and structure of management, financial condition and
performance, ownership and other strategic issues. On January 22, 1997,
representatives of Austin Associates delivered the results of the strategic
planning process to the Board of Directors of Farmers.
 
     Over approximately the next four weeks, members of the Board of Directors
of Farmers considered the results of the Austin Associates report and determined
that a sale or merger of Farmers would likely provide greater shareholder value
than remaining independent. On February 27, 1997, the Board retained Austin
Associates to serve as financial advisor with respect to a possible sale or
merger of Farmers.
 
     On March 7, 1997, Austin Associates began contacting potential purchasers.
Thirty potential purchasers were contacted either by telephone or in writing.
Twenty potential purchasers executed confidentiality agreements, and were
provided confidential information packages on or about March 21, 1997. The
deadline for submission of indications of interest was April 18, 1997. Seven
proposals were received.
 
                                       13
<PAGE>   27
 
     On April 28, 1997, representatives of Austin Associates met with the Board
of Directors of Farmers to review and evaluate the seven proposals. Two
proposals were eliminated as being inadequate. One proposal was considered to be
marginally adequate, but when that offeror was invited to perform a due
diligence investigation of Farmers, it declined to do so.
 
     During the months of May and early June, 1997, the remaining four
organizations conducted due diligence investigations of Farmers. These four
organizations then submitted final proposals on June 6, 1997.
 
     The Farmers Board met on June 11, 1997 to review and evaluate the final
four proposals. At that meeting, the Board determined that the offer received
from First Citizens was superior to the other three proposals. In addition, the
Board of Directors of Farmers was cognizant of First Citizens' intention to
retain Farmers' charter, its name and its community banking philosophy.
 
     During the last several weeks of June, First Citizens and Farmers and their
respective representatives negotiated the financial and other terms of the
Reorganization Agreement on an "arm's length" basis. Farmers and First Citizens
entered into the Reorganization Agreement on July 3, 1997.
 
     The Reorganization Agreement was amended on November 25, 1997 to extend the
deadline for consummation of the Merger from February 1, 1998 to February 28,
1998. The Reorganization Agreement was amended again on November 26, 1997 to
remove certain time constraints relating to the consummation of the Merger and
reduce the Exchange Ratio from 6.5 to 6.06. Each such amendment was approved in
advance by the respective Boards of First Citizens and Farmers. The Merger
Agreement was executed by Farmers, First Citizens and Farmers Interim Bank on
November 26, 1997.
 
  Reasons for the Merger
 
     In reaching the determination that the Merger is fair to, and in the best
interests of, Farmers' shareholders, the Farmers' Board consulted with Farmers'
management, as well as its financial and legal advisors, and considered a number
of factors, including, without limitation, the following, which include all of
the material factors considered:
 
          (i) the business earnings and potential for future growth and
     prospects of Farmers and First Citizens, (ii) the potential operational and
     managerial benefits that will be derived from the Merger, (iii) the
     consideration to be received by Farmers shareholders in the Merger in
     relation to the book value and earnings of Farmers, (iv) the prices paid
     for Farmers' Common Shares in the limited trades known to Farmers'
     management, (v) the prices paid in similar merger transactions, (vi) the
     increased dividend rate; (vii) the tax-free nature of the stock-for-stock
     exchange; and (viii) the comparatively greater liquidity that Farmers'
     shareholders might enjoy by being shareholders of a larger institution.
 
     The Board of Directors also considered its belief that First Citizens
shared a community banking philosophy that would benefit the employees,
depositors and customers of Farmers and the communities it serves and that the
Merger would allow Farmers to offer a diversity of products and services to its
customers.
 
     The Farmers Board considered many different factors in its evaluation and
did not believe it was practical to and did not quantify or otherwise assign
relative weights to the individual factors considered in reaching its
determination.
 
RECOMMENDATION OF THE FARMERS BOARD OF DIRECTORS
 
     IN VIEW OF ALL THE CONSIDERATIONS DESCRIBED ABOVE, THE BOARD OF DIRECTORS
OF FARMERS UNANIMOUSLY CONCLUDED THE MERGER IS IN THE BEST INTERESTS OF AND IS
FAIR TO THE FARMERS SHAREHOLDERS AND RECOMMENDS THAT FARMERS' SHAREHOLDERS VOTE
FOR THE MERGER.
 
DESCRIPTION OF THE MERGER
 
     Upon consummation of the transactions contemplated under the Merger
Agreement, Farmers Interim Bank will be merged with and into Farmers. Farmers
will be the surviving bank after the Merger and the Articles of
 
                                       14
<PAGE>   28
 
Incorporation of Farmers will remain in effect as they were immediately prior to
the Merger. After the Merger, Farmers will be a wholly-owned subsidiary of First
Citizens and will continue to be known as "The Farmers State Bank of New
Washington, Ohio." See also "PROPOSED MERGER -- Operations of Farmers After the
Merger."
 
EXCHANGE OF FARMERS COMMON SHARES
 
     Upon consummation of the Merger, each shareholder of Farmers who does not
dissent will have the right to receive 6.06 First Citizens Common Shares for
each Farmers Common Share exchanged therefor, plus cash in lieu of the issuance
of fractional shares. Based on the last reported sale price of $          for
First Citizens Common Shares on the Nasdaq Bulletin Board on December   , 1997,
the value of First Citizens Common Shares multiplied by the Exchange Ratio as of
that date would have been $          . The market value of First Citizens Common
Shares to be received in the Merger is subject to fluctuation. Fluctuations in
the market price of First Citizens Common Shares would generally result in an
increase or decrease in the value of the consideration to be received by Farmers
shareholders in the Merger. An increase in the market value of First Citizens
Common Shares would generally increase the value of the consideration to be
received by Farmers shareholders in the Merger. A decrease in the market value
of First Citizens Common Shares would generally have the opposite effect.
 
FAIRNESS OPINION OF MCDONALD & COMPANY
 
     First Citizens has retained McDonald & Company as its financial advisor in
connection with the Merger and requested that McDonald & Company render its
opinion with respect to the fairness, from a financial point of view, of the
Exchange Ratio to the holders of First Citizens Common Shares. McDonald &
Company rendered its oral opinion to the Board of Directors of First Citizens on
July 2, 1997, which it subsequently confirmed in writing, that as of the date of
such opinion, the Exchange Ratio pursuant to the Merger was fair, from a
financial point of view, to the holders of First Citizens Common Shares.
 
     THE FULL TEXT OF THE OPINION OF MCDONALD & COMPANY, UPDATED AS OF THE DATE
OF THIS PROXY STATEMENT/PROSPECTUS, WHICH SETS FORTH CERTAIN ASSUMPTIONS MADE,
MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEWS UNDERTAKEN, IS ATTACHED AS
APPENDIX D TO THIS PROXY STATEMENT/PROSPECTUS, AND SHOULD BE READ IN ITS
ENTIRETY. THE SUMMARY OF THE OPINION OF MCDONALD & COMPANY SET FORTH IN THIS
PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE
OPINION. MCDONALD & COMPANY'S OPINION SHOULD NOT BE CONSTRUED BY HOLDERS OF
FIRST CITIZENS' COMMON SHARES AS A RECOMMENDATION AS TO HOW SUCH HOLDERS SHOULD
VOTE AT THE SPECIAL MEETING.
 
     In arriving at its opinion, McDonald & Company reviewed, among other
things, the Reorganization Agreement together with exhibits and schedules
thereto, certain publicly available information relating to the business,
financial condition and operations of First Citizens and Farmers as well as
certain other nonpublic information, primarily financial in nature, furnished to
it by First Citizens and Farmers relating to the respective businesses,
earnings, assets, financial forecasts and prospects. McDonald & Company also
held discussions with members of senior management of First Citizens and Farmers
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, First
Citizens Common Shares and Farmers Common Shares and certain publicly available
information concerning comparable companies and transactions, all as more fully
set forth in McDonald & Company's opinion.
 
     McDonald & Company was not engaged to and did not conduct a physical
inspection of any of the assets, properties or facilities of either First
Citizens or Farmers, and was not engaged to conduct 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 First Citizens or
Farmers. 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, has relied upon the
representations and warranties of First Citizens and Farmers contained in the
Reorganization Agreement, and has not independently attempted to verify any such
information. McDonald & Company has also assumed that all of the conditions to
the Merger as set forth in the Reorganization
 
                                       15

Agreement, including the tax-free nature of the reorganization for federal
income tax purposes, would be consummated on a timely basis in the manner
contemplated by the Reorganization Agreement. No limitations were imposed by
First Citizens 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 written opinion dated July 3, 1997, and as
updated to the date hereof, 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 of the factors considered by McDonald & Company without considering
all 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 and discussed with the First Citizens Board of Directors, in connection
with McDonald & Company's opinion dated July 3, 1997:
 
  Introduction
 
     McDonald & Company calculated the offer price per share, offer price to
March 31, 1997 book value, offer price to last twelve months earnings per share
at March 31, 1997, and offer price to estimated 1998 earnings per share for
Farmers implied by the Exchange Ratio. Using First Citizens' July 1, 1997
closing bid price of $34.50, the Exchange Ratio implied a price per share for
Farmers of $224.25, a price to book value of 299.5%, a price to last twelve
months earnings per share of 24.7x and a price to estimated 1998 earnings per
share of 27.6x. Earnings per share estimates were based upon the financial
forecasts of management of First Citizens and Farmers.
 
  Comparison with Selected Companies
 
     McDonald & Company compared the financial performance and stock market
valuation of First Citizens with corresponding data for the following selected
companies: Ambanc Corp., ANB Corp., Beverly Bancorporation Inc., CoBancorp,
Inc., German American Bancorp, Oak Hill Financial Inc., Peoples Bancorp Inc.,
Peoples Bank of Indianapolis, Southside Bancshares Corp., State Financial
Services and Shoreline Financial Corp. (collectively, the "First Citizens Peer
Group") This analysis indicated, among other things, that (i) the median price
to last twelve months earnings per share for the First Citizens Peer Group was
16.2x, as compared to First Citizens' multiple of price to last twelve months
earnings per share of 27.2x, and (ii) the median price to book value per share
for the First Citizens Peer Group was 193%, as compared to First Citizens'
multiple of price to book value per share of 303%. McDonald & Company also noted
that all of the companies in the First Citizens Peer Group were listed on the
Nasdaq National Market and that First Citizens' return on average equity for the
twelve month period ended March 31, 1997 was 11.23%, as compared to the median
return on average equity for the First Citizens Peer Group of 13.29%.
 
     McDonald & Company also compared the financial performance and stock market
valuation of Farmers with corresponding data for the following selected
companies: ANB Corp., Commercial BancShares, Inc., First WV Bancorp Inc., German
American Bancorp, Oak Hill Financial Inc., Peoples Bank of Indianapolis, S.Y.
Bancorp Inc. and United Bancorp Inc. (collectively, the "Farmers Peer Group")
This analysis indicated, among other things, that (i) the median price to last
twelve months earnings per share for the Farmers Peer Group was 14.5x, and (ii)
the median price to book value per share for the Farmers Peer Group was 180%.
 
     At the time, none of the companies in the First Citizens Peer Group or the
Farmers Peer Group had announced a merger transaction or disclosed a possible
interest in pursuing a possible merger transaction which could have
significantly affected the stock market valuations of such companies.

  Contribution Analysis
 
     McDonald & Company analyzed the contribution of each of Farmers and First
Citizens to, among other things, the shareholders' equity and after-tax net
income of the pro forma combined company. This analysis showed that, among other
factors, Farmers would have contributed 33.2%, 30.1%, and 31.8% of the assets,
shareholders' equity, and net income of the pro forma combined company as of and
for the twelve months ended March 31, 1997, respectively. This compared with a
proposed ownership of 29.9% of the combined company to be held by holders of
Farmers Common Shares.
 
  Pro Forma Merger Analyses
 
     McDonald & Company analyzed certain pro forma effects resulting from the
Merger on the pro forma combined company over a five year period from 1998
through 2002. This analysis, based upon the financial forecasts of management of
First Citizens and Farmers and including estimates of cost savings provided by
the management of First Citizens and Farmers, showed approximately 2.6% dilution
for First Citizens in pro forma earnings per share in 1998 and approximately
2.4% dilution in pro forma earnings per share in 1999. McDonald & Company also
analyzed the changes in per share amount of earnings, book value and indicated
dividend represented by one share of First Citizens Common Shares after the
Merger. The analysis was performed on the basis of financial information for
both companies as of and for the years ended December 31, 1995 and December 31,
1996, and as of and for the twelve months ended March 31, 1997. The analysis
indicated, among other things, that exchanging one Farmers Common Share at the
Exchange Ratio for First Citizens Common Shares on a pro forma basis would have
resulted in a 2.9% increase in earnings per share for each First Citizens Common
Share for the twelve months ended March 31, 1997, a 0.3% increase in book value
per First Citizens Common Share as of March 31, 1997, and no change in dividends
per First Citizens Common Share based on First Citizens' indicated annual
dividend rate as of July 2, 1997.
 
  Analysis of Selected Merger Transactions
 
     McDonald & Company reviewed five groups of selected pending and completed
bank merger transactions involving (i) selling banks headquartered in the
Midwest region; (ii) selling banks having total assets of between $100 million
and $400 million; (iii) selling banks having an equity to assets ratio of
between 9.00% and 10.50%; (iv) selling banks having a return on average assets
ratio of between 1.10% and 1.50%; and (v) selling banks having non-performing
assets as a percent of total assets of between 0.80% and 1.30%. 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 median ratios and multiples for each group. The calculations yielded
ranges of median ratios of price to stated book value of 172% to 218%. Median
ratios of price to tangible book value ranged from 174% to 228%. Median
multiples of earnings among the five groups ranged from 15.1x to 20.6x. Median
ratios of offer value to assets ranged from 16.5% to 21.3%. Applying the median
of the medians for each of these four ratios to Farmers' actual per share
financial data as of March 31, 1997 showed an imputed reference range of $130 to
$160 per share of Farmers Common Shares.
 
     NO COMPANY OR TRANSACTION USED IN THE ABOVE ANALYSES AS A COMPARISON IS
IDENTICAL TO FIRST CITIZENS, FARMERS, OR THE MERGER. ACCORDINGLY, AN ANALYSIS OF
THE RESULTS OF THE FOREGOING NECESSARILY INVOLVES COMPLEX CONSIDERATIONS AND
JUDGMENTS 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 Farmers could
produce over a five year period from 1998 through 2002, under various
assumptions, based upon First Citizens and Farmers management's forecasts.
McDonald & Company
 
                                       17
<PAGE>   31
 
then estimated the terminal value of Farmers 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 12.0x to
16.0x. The five-year 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
Farmers. On the basis of such varying assumptions, this discounted cash flow
analysis indicated a reference range of $103 to $138 per share of Farmers Common
Shares. This analysis was based upon First Citizens and Farmers management's
forecasts, including variations and assumptions made by McDonald & Company,
which included adjustments to reflect the anticipated effects of potential
merger-related cost savings estimated by First Citizens and Farmers.
Management's projections are based upon many factors and assumptions, many of
which are beyond the control of First Citizens or Farmers. As indicated above,
this analysis is not necessarily indicative of actual values or actual future
results and does not purport to reflect the prices at which any securities may
trade at the present time or at any time in the future.
 
  Other Analysis
 
     In addition to performing the analyses summarized above, McDonald & Company
also considered its analysis of the general market for bank and thrift mergers,
Farmers' relative share of the deposit market that it serves and the general
economic conditions and prospects of those markets.
 
     In arriving at its opinion, McDonald & Company placed significant weight on
the Pro Forma Merger Analysis and Contribution Analysis. The disparity between
the valuation levels of the First Citizens Common Shares and the First Citizens
Peer Group (and other bank stocks) affects the comparison of the value of the
Merger in nominal terms to the value indicated in the Analysis of Comparable
Companies, Selected Merger Transactions and Discounted Cash Flow above.
Application of these three valuation techniques to the proposed Merger indicated
that an Exchange Ratio lower than that contemplated by the Reorganization
Agreement would have been appropriate. However, the relative illiquidity of the
market for First Citizens Common Shares, the lack of a research following and
the small number of market makers for the First Citizens Common Shares, as well
as the relationship of various measures of First Citizens' financial performance
to those for companies included in the First Citizens Peer Group led McDonald &
Company to give more weight to valuation methods in which the market valuation
of First Citizens Common Shares was not a central component of the analysis. In
rendering its oral opinion to the Board of Directors of First Citizens on July
2, 1997, McDonald & Company discussed with the First Citizens Board of Directors
its determination that First Citizens Common Shares were valued at significantly
higher multiples of earnings and book value as compared to both the First
Citizens Peer Group and other potential acquirors of Farmers. McDonald & Company
also extensively discussed with the First Citizens Board of Directors the
implications that such trading multiples would have on First Citizens' ability
to offer Farmers a nominally higher offer value in a stock for stock exchange
while limiting the dilution in ownership and earnings per share to the current
First Citizens shareholders.
 
     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 First Citizens Board of Directors were
one of many factors taken into consideration by the First Citizens Board of
Directors in making its determination to approve the Reorganization Agreement.
Consequently, the McDonald & Company analyses described above should not be
viewed as determinative of the First Citizens Board of Directors' conclusions
with respect to the value of Farmers or of the decision of the First Citizens
Board of Directors to agree to the Exchange Ratio.
 
                                       18
<PAGE>   32
 
     McDonald & Company's opinion is 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 opinion does not address First Citizens'
underlying business decision to effect the Merger or any other terms of the
Merger. McDonald & Company is not rendering any opinion as to the value of First
Citizens Common Shares or Farmers Common Shares at the Effective Time.
 
     In connection with its opinion dated as of the date of this Joint Proxy
Statement/Prospectus, 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. As a part of these procedures, McDonald &
Company considered the change in the Exchange Ratio to 6.06 as agreed to by
Farmers and First Citizens on November 26, 1997 and that certain historical
financial statements for Farmers have been restated.
 
     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. First
Citizens' 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 Merger. McDonald & Company is not affiliated with
either First Citizens or Farmers.
 
     In the ordinary course of business, McDonald & Company makes a market in
First Citizens Common Shares and may actively trade the securities of First
Citizens and Farmers 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 has provided investment banking
services to First Citizens in the past for which it has received customary
compensation and may provide such services to First Citizens in the future.
 
     For its services as financial advisor, First Citizens has paid McDonald &
Company a retainer of $15,000 and a fee of $35,000 upon the rendering of
McDonald & Company's July 2, 1997 oral fairness opinion. Additional fees equal
to approximately $125,000 will be payable to McDonald & Company upon
consummation of the Merger. First Citizens 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.
 
FAIRNESS OPINION OF AUSTIN ASSOCIATES
 
     Austin Associates is a recognized investment banking firm regularly engaged
in the valuation of financial institutions and other businesses and their
securities in connection with mergers and acquisitions and in valuation for
estate, corporate and other purposes. Farmers selected Austin Associates to
serve as financial adviser in connection with the Merger on the basis of its
reputation and qualifications in representing financial institutions in mergers
and acquisitions.
 
     Austin Associates orally advised Farmers' Board of Directors as of July 3,
1997, and has rendered a written opinion to Farmers' Board of Directors as of
the date hereof, to the effect that the terms of the Merger are fair from a
financial point of view to the shareholders of Farmers as of the date of the
opinion. A copy of Austin Associates' fairness opinion is attached as Appendix E
to this Proxy Statement/Prospectus and should be read in its entirety. Austin
Associates based its opinion upon, among other things: (i) a comparison of the
financial statements and other financial information concerning Farmers and
First Citizens set forth or incorporated by reference in this Proxy
Statement/Prospectus; (ii) certain other financial information concerning
Farmers, including, but not limited to, operating budgets and loan loss reserve
adequacy reports; (iii) financial and share price data of Farmers, First
Citizens and comparable banking organizations; (iv) the financial terms, to the
extent publicly available, of certain comparable transactions; (v) the terms of
certain other proposals received by Farmers from other banking institutions; and
(vi) discussions with the management of Farmers and First Citizens.
 
     THE FULL TEXT OF THE OPINION OF AUSTIN ASSOCIATES, UPDATED AS OF THE DATE
OF THIS PROXY STATEMENT/PROSPECTUS, WHICH SETS FORTH CERTAIN ASSUMPTIONS MADE,
MATTERS CONSIDERED AND LIMITATIONS ON THE
 
                                       19
<PAGE>   33
 
REVIEWS UNDERTAKEN, IS ATTACHED AS APPENDIX E TO THIS PROXY
STATEMENT/PROSPECTUS, AND SHOULD BE READ IN ITS ENTIRETY. THE SUMMARY OF THE
OPINION OF AUSTIN ASSOCIATES SET FORTH IN THIS PROXY STATEMENT/PROSPECTUS IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE OPINION. AUSTIN ASSOCIATES'
OPINION SHOULD NOT BE CONSTRUED BY HOLDERS OF FARMERS' COMMON SHARES AS A
RECOMMENDATION AS TO HOW SUCH HOLDERS SHOULD VOTE AT THE SPECIAL MEETING.
 
     The terms of the Reorganization Agreement were determined by First Citizens
and Farmers, and their representatives, after arm's-length negotiations between
the parties. Austin Associates participated in the negotiations on behalf of
Farmers.
 
     In connection with rendering its opinion, Austin Associates performed a
variety of financial analyses, which are summarized below. Austin Associates
believes its analyses must be considered as a whole and that selecting portions
of such analyses and the factors considered therein, without considering all
factors and analyses, could create an incomplete view of the analyses and the
process underlying the Austin Associates opinion. The preparation of a fairness
opinion is a complex process involving subjective judgments and is not
necessarily susceptible to partial analyses or summary description. In its
analyses, Austin Associates made numerous assumptions with respect to industry
performance, business and economic conditions, and other matters, many of which
are beyond Farmers' or First Citizens' control. Any estimates contained in
Austin Associates' analyses are not necessarily indicative of future results or
values, which may be significantly more or less favorable than the estimates.
 
  The Process for Soliciting Indications of Interest from Potential Purchasers
 
     After analysis and discussions between Austin Associates and Farmers,
thirty potential purchasers were contacted to determine their potential interest
in acquiring Farmers. Of the organizations contacted, twenty requested
confidential information packages which provided detailed information regarding
the business and operations of Farmers. Each organization provided information
was requested to submit a specific proposal to acquire Farmers. Austin
Associates pursued discussions with each organization that had requested the
confidential information. As a result of this process, seven organizations
submitted proposals to acquire Farmers. The Farmers Board selected the First
Citizens proposal after extensive deliberation and negotiation.
 
  Comparative Price Analysis
 
     Austin Associates reviewed a comparison of prices paid in selected sale of
control transactions announced in Ohio between January 1, 1995 and November 30,
1997, for banks having assets of between $23 million and $194 million. The 11
transactions reviewed had an average price to book value ratio of 221 percent
and a price to earnings multiple of 22.1 times. The median multiples were 207
percent of book value and 21.8 times earnings. The market value of the
consideration to be received by Farmers shareholders in the Merger is estimated
at 262 percent of Farmers' book value at September 30, 1997, based on an
aggregate transaction value of $41.8 million. The transaction value was computed
using the July 2, 1997 market price of First Citizens of $34.50 per share. The
market value of the consideration is further estimated to equal 26.1 times
Farmers' consolidated earnings per share for the year ended December 31, 1996
and 31.6 times annualized earnings per share for the nine months ended September
30, 1997.
 
  Contribution Analysis
 
     Austin Associates compared the pro forma ownership interest in First
Citizens that Farmers shareholders would receive, in the aggregate, to the
contribution by Farmers to the total assets, equity and net income in the
combined organization. Assuming a September 30, 1997, closing date for the
Merger, Farmers shareholders would own approximately 28.4 percent of First
Citizens on a pro forma basis. Farmers' contribution of total assets would equal
32.9 percent, the contribution of total equity would equal 30.6 percent, and the
contribution of net income for the nine months ending September 30, 1997 would
have equaled 26.1 percent. The contribution of net income for the year ended
December 31, 1996 would have equaled 28.8 percent.
 
                                       20
<PAGE>   34
 
  Dilution Analysis
 
     Austin Associates also reviewed the pro forma effect of the Merger on
Farmers' and First Citizens' December 31, 1996 and September 30, 1997 earnings
per share and book value per share. Farmers recorded earnings per share in 1996
of $8.02 and a book value of $73.42 per share as of year end 1996. Giving effect
to the Merger, the equivalent Farmers earnings per share would have equaled
$7.94, a decrease of 1.0 percent from actual results. Book value per share would
have decreased to $69.21 per share, a decrease of 5.7 percent from actual book
value. Giving effect to the Merger, First Citizens' book value per share would
have been increased by $0.14 or 1.2 percent, and earnings per share would have
been increased by $0.01 or 0.8 percent.
 
     Farmers recorded year to date earnings per share of $4.96 and a book value
of $79.77 per share as of September 30, 1997. Giving effect to the Merger, the
equivalent Farmers earnings per share would have equaled $5.39, an increase of
8.7 percent over actual results. Book value per share would have decreased to
$73.99 per share, a decrease of 7.2 percent from actual book value. Giving
effect to the Merger, First Citizens' book value per share would have been
increased by $0.38 or 3.2 percent, and earnings per share would have been
decreased by $0.03 or 3.3 percent.
 
  Dividends
 
     Austin Associates reviewed the current cash dividends paid by Farmers and
First Citizens. Based on the exchange ratio of 6.06 First Citizens shares for
each share of Farmers, equivalent dividends to Farmers shareholders would have
been $6.18 for the year ended December 31, 1996, a 341 percent increase over
actual dividends received by Farmers shareholders of $1.40 per share.
 
     The summary set forth above does not purport to be a complete description
of the analyses performed by Austin Associates. Further, Austin Associates did
not conduct a physical inspection of any of the properties or assets of Farmers
or First Citizens. Austin Associates has assumed and relied upon the accuracy
and completeness of the financial and other information provided to it or
publicly available, has relied upon the representations and warranties of
Farmers and First Citizens made pursuant to the Reorganization Agreement, and
has not independently attempted to verify any of such information. Austin
Associates has also assumed that the conditions to the Merger as set forth in
the Reorganization Agreement would be satisfied and that the Merger would be
consummated on a timely basis in the manner contemplated by the Reorganization
Agreement. No limitations were imposed by Farmers or First Citizens on the scope
of Austin Associates' investigation nor were any specific instructions given to
Austin Associates in connection with its fairness opinion.
 
     For Austin Associates' services as financial advisor, Farmers will pay the
firm a fee of $40,000, plus a contingent amount equal to 1.00 percent of the
transaction value when the Merger is consummated. In addition, Farmers has
agreed to reimburse Austin Associates for reasonable out-of-pocket expenses and
indemnify Austin Associates against certain liabilities, including liabilities
under the securities laws.
 
EFFECTIVE TIME OF THE MERGER
 
     As used in this Proxy Statement/Prospectus, "Effective Time" means the date
and time when the Merger becomes effective, which will occur upon the filing
with the Ohio Secretary of State of a certified copy of the Merger Agreement, a
certificate of approval from the Ohio Department of Commerce, Division of
Financial Institutions ("ODFI") in accordance with Sections 1121.05 and 1121.06
of the ORC and a certificate of adoption certifying that the Merger has been
approved by Farmers' Board of Directors and shareholders.
 
PAYMENT OF CASH IN LIEU OF FRACTIONAL SHARES
 
     No fractional First Citizens Common Shares will be issued in connection
with the Merger. Each Farmers shareholder who would otherwise have been entitled
to receive a fraction of a First Citizens Common Share will receive, in lieu
thereof, cash therefor, without interest, at a price based upon $33.50 per share
of First Citizens Common Shares.
 
                                       21
<PAGE>   35
 
SURRENDER OF CERTIFICATES
 
     Following approval of the Merger by the respective shareholders of Farmers
and First Citizens, each Farmers' shareholder will receive a Letter of
Transmittal, together with instructions, for use in surrendering certificates
representing Farmers Common Shares ("Old Certificates") in exchange for First
Citizens Common Shares and handling the payment of cash in lieu of fractional
First Citizens Common Shares. The Letter of Transmittal will instruct
surrendering shareholders to send their Old Certificates to Fifth Third Bank, as
exchange agent (the "Exchange Agent"), duly endorsed for transfer or accompanied
by a duly endorsed assignment separate from the certificate(s). If the Merger is
consummated, the Old Certificates surrendered will be exchanged for one or more
certificates representing the whole number of First Citizens Common Shares based
on the Exchange Ratio and payment of cash in lieu of fractional shares. Until so
surrendered, each outstanding Old Certificate shall be deemed from and after the
Effective Time for all purposes to represent only the right to receive, upon
surrender, one or more certificates for First Citizens Common Shares and cash in
lieu of fractional shares. If the Merger is not consummated, the Exchange Agent
will return any Old Certificates it has received to the persons surrendering
such Old Certificates in accordance with the Letter of Transmittal and
instructions.
 
     If any certificates for First Citizens Common Shares are to be issued in a
name(s) other than that in which an Old Certificate surrendered or exchanged is
issued, the Old Certificate so surrendered must be properly endorsed and
otherwise in proper form for transfer. The person requesting the exchange must
affix any requisite stock transfer tax stamps to the Old Certificate
surrendered, provide funds for their purchase, or establish to the satisfaction
of the Exchange Agent that such taxes have been paid or are not applicable.
 
     In the event of a lost certificate, the shareholder shall provide, in lieu
of the lost certificate, an affidavit attesting to the loss of said certificate
and, if required by Farmers or the Exchange Agent, an indemnification or bond in
such reasonable amount as Farmers or the Exchange Agent may direct. Unless and
until the Old Certificates, or affidavit and, if required by the Surviving Bank
or the Exchange Agent, an indemnification or bond in lieu thereof, are presented
to the Exchange Agent, the holder thereof shall not be entitled to receive any
consideration to be paid in connection with the Merger or any dividends payable
on First Citizens Common Shares, or to exercise any rights as a holder of First
Citizens Common Shares. On or after the Effective Time, upon surrender of the
Old Certificates, or affidavit and an indemnification or bond in lieu thereof,
to the Exchange Agent, the holder thereof will be paid the consideration to
which the holder is entitled under the Merger Agreement and any dividends which
theretofore became payable on any First Citizens Common Shares to which the
holder is entitled. No dividends or other distributions, if any, payable to the
holders of record of First Citizens Common Shares as of any date subsequent to
the Effective Time shall be paid to any holder of any outstanding Old
Certificate until the holder thereof surrenders such Old Certificate as provided
in the Merger Agreement. Subject to applicable law, no holder of an Old
Certificate shall be entitled to vote or exercise any other rights of a holder
of First Citizens Common Shares.
 
     After the consummation of the Merger, there will be no transfers on the
stock transfer books of Farmers of any Farmers Common Shares. If, after the
consummation of the Merger, Old Certificates are properly presented to First
Citizens, they will be canceled and exchanged for the consideration specified in
the Merger Agreement, subject to applicable law and to the extent that First
Citizens has not paid such consideration to a public official pursuant to
applicable abandoned property laws.
 
INTEREST OF MANAGEMENT IN THE MERGER
 
     The Reorganization Agreement provides that First Citizens will offer the
existing full time employees of Farmers the opportunity to continue as employees
of the Surviving Bank following the Merger. The Reorganization Agreement further
provides, however, that such commitment shall not be deemed to be a contract of
employment or construed to give Farmers' employees any rights other than as
employees at will under Ohio law and Farmers' employees shall not be deemed to
be third-party beneficiaries of such commitment. Farmers employees who continue
as employees of the Surviving Bank following the Merger will have their years of
service credited toward eligibility and vesting in First Citizens' pension,
savings and retirement plans and will be entitled to participate in a variety of
on-going educational and training programs offered by First Citizens and its
 
                                       22

subsidiaries. In addition, two members of Farmers' current Board of Directors
shall have the right to serve on the Board of Directors of First Citizens,
effective at or prior to First Citizens' 1998 shareholder meeting.
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
     Shareholders of Farmers are entitled to certain dissenters' rights pursuant
to Section 1701.85 of the ORC. Sections 1701.85 and 1115.19 generally provide
that shareholders of Farmers will not be entitled to such rights absent
compliance with Section 1701.85 and failure to take any one of the required
steps may result in the termination or waiver of such rights. Specifically, any
Farmers shareholder who is a record holder of Farmers Common Shares on the
Farmers Record Date and whose shares are not voted in favor of the Merger may be
entitled to be paid the "fair cash value" of such Farmers Common Shares after
the Effective Time. To be entitled to such payment, a shareholder must deliver a
written demand for payment therefor to Farmers on or before the tenth day
following the Special Meeting and must otherwise comply with Section 1701.85.
Any written demand must specify the shareholder's name and address, the number
and class of shares held by him or her on the Farmers Record Date, and the
amount claimed as the "fair cash value" of said Farmers Common Shares. See the
text of Sections 1115.19 and 1701.85 of the ORC attached as Appendix C to this
Proxy Statement/Prospectus for specific information on the procedure to be
followed in exercising dissenters' rights.
 
     If Farmers so requests, dissenting shareholders must submit their share
certificates to Farmers within fifteen days of such request, for endorsement
thereon by Farmers that demand for appraisal has been made; failure to comply
with such request could terminate the dissenting shareholders' rights. Such
certificates will be promptly returned to the dissenting shareholders by
Farmers. If Farmers and any dissenting shareholder cannot agree upon the "fair
cash value" of the Farmers Common Shares, either may, within three months after
service of demand by the shareholder, file a petition in the Court of Common
Pleas of Crawford County, Ohio (the "Court") for a determination of the "fair
cash value" of said Farmers Common Shares. The Court may appoint one or more
appraisers to determine the "fair cash value" and if the Court approves the
appraisers' report, judgment will be entered therefor, and the costs of the
proceedings, including reasonable compensation of the appraisers, will be
assessed or apportioned as the Court considers equitable.
 
FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
     The following summary of the material federal income tax consequences of
the Merger to holders who hold Farmers Common Shares as capital assets and deals
only with holders who are (i) citizens or residents of the United States, (ii)
domestic corporations or (iii) otherwise subject to United States federal income
tax on a net income basis in respect of Shares ("U.S. Holders"). This summary
may not apply to certain classes of taxpayers, including, without limitation,
insurance companies, tax-exempt organizations, financial institutions, dealers
in securities, persons who acquired Farmers Common Shares pursuant to the
exercise of employee stock options or rights or otherwise as compensation and
persons who hold shares of Farmers Common Shares in a hedging transaction or as
part of a straddle or conversion transaction. Also, the summary does not address
state, local or foreign tax consequences of the Merger. Consequently, each
holder should consult such holder's own tax advisor as to the specific tax
consequences of the Merger to such holder.
 
     This summary is based on current law and the opinion of counsel to Farmers.
Future legislative, judicial or administrative changes or interpretations, which
may be retroactive, could alter or modify the statements set forth herein. The
opinion of Werner & Blank Co., L.P.A. set forth in this summary is based, among
other things, on assumptions relating to certain facts and circumstances of, and
the intentions of the parties to, the Merger, which assumptions have been made
with the consent of Farmers and First Citizens. Neither Farmers nor First
Citizens has requested, and neither Farmers nor First Citizens will request, any
ruling from the Internal Revenue Service as to the federal income tax
consequences of the Merger.
 
     It is intended that the Merger will be treated as a reorganization within
the meaning of Section 386(a) of the Code, and that, accordingly, for federal
income tax purposes no gain or loss will be recognized by Farmers as a result of
the Merger.
 
                                       23
<PAGE>   37
 
     In the opinion of Werner & Blank Co., L.P.A., the material federal income
tax consequences to U.S. Holders who exchange shares of Farmers Common Shares
for shares of First Citizens Common Shares, pursuant to the Merger will be as
follows:
 
          (i) The Merger will constitute a "Statutory Merger" within the meaning
     of Section 368(a)(1)(A) and (a)(2)(E) of the Code and Farmers Interim Bank,
     Farmers and First Citizens will each be a "party to a reorganization"
     within the meaning of Section 368(b) of the Code.
 
          (ii) No gain or loss will be recognized by Farmers as a result of the
     Merger.
 
          (iii) No gain or loss will be recognized by Farmers shareholders who
     exchange their Farmers Common Shares solely for First Citizens Common
     Shares in the Merger.
 
          (iv) The federal income tax basis of the First Citizens Common Shares
     received by Farmers shareholders in the Merger will be the same as the
     federal income tax basis in the Farmers Common Shares exchanged therefor,
     respectively.
 
          (v) The holding period for the First Citizens Common Shares received
     by each Farmers shareholder in the Merger will include the period during
     which the Farmers Common Shares exchanged therefor were held, provided that
     the exchanged Farmers Common Shares were held as capital assets by such
     Farmers shareholder on the date of the exchange.
 
          (vi) The payment of cash in lieu of fractional shares for the purpose
     of mechanically rounding off the fractions resulting from the exchange
     will, in each instance, constitute a distribution not essentially
     equivalent to a dividend within the meaning of Section 302(b)(1) of the
     Code. The amount received will be treated as a distribution in full payment
     in exchange for such Farmers shareholder's fractional share of interest
     under Section 302(a) of the Code.
 
     The obligation of Farmers and First Citizens to consummate the Merger is
conditioned on the receipt by Farmers of an opinion of its counsel, Werner &
Blank Co., L.P.A., dated as of the closing date of the Merger, substantially to
the effect that (i) the Merger will constitute a tax free reorganization, (ii)
no gain or loss will be recognized by Farmers as a consequence of the Merger,
(iii) no gain or loss will be recognized by the Farmers shareholders upon the
receipt solely of First Citizens Common Shares in exchange for Farmers Common
Shares, except with respect to any cash received in lieu of a fractional share
interest in First Citizens Common Shares, (iv) the federal income tax basis of
the First Citizens Common Shares received by the Farmers shareholders for their
Farmers Common Shares will be the same as the federal income tax basis of the
Farmers Common Shares surrendered in exchange therefor, and (v) the holding
period for the First Citizens Common Shares received by each Farmers Shareholder
in exchange for Farmers Common Shares will include the period for which the
Farmers Common Shares exchanged therefor were held, provided that the exchanged
Farmers Common Shares were held as capital assets by such Farmers shareholder.
Farmers shareholders who exercise dissenters' rights and receive cash for their
Farmers Common Shares will be treated as having received a distribution in
redemption of their shares which will result in such shareholders receiving
income for federal income tax purposes. The opinion of Werner & Blank Co.,
L.P.A. referred to in this paragraph will be based upon certain facts,
assumptions and representations and/or covenants, including those contained in
certificates of officers of Farmers, First Citizens and, possibly, others.
Subject to the receipt of such representations and/or covenants, Werner & Blank
Co., L.P.A. anticipates that it will render such opinion.
 
REGULATORY APPROVALS
 
     First Citizens has filed the applications necessary to obtain the approval
for the Merger from the Federal Reserve Board, the ODFI and the Federal Deposit
Insurance Corporation (the "FDIC"). The Merger may not be consummated for 15
days after approval by the Federal Reserve Board, during which time an action
may be brought by the United States Department of Justice challenging the Merger
on antitrust grounds. Neither First Citizens nor Farmers has any reason to
believe the Merger will be challenged on antitrust grounds.

BUSINESS PENDING THE MERGER
 
     The Reorganization Agreement provides that, pending consummation of the
Merger, Farmers will, among other things: (i) continue to operate in the
ordinary course; (ii) promptly advise First Citizens in writing of all material
actions taken by the directors and shareholders of Farmers and all developments
which, in the opinion of Farmers, may have a material adverse effect upon the
business, properties or condition (either financial or otherwise) of Farmers;
(iii) refrain from issuing, selling or granting any option for, or acquire for
value any shares of its capital stock or otherwise effecting any change in
connection with its capitalization; (iv) subject to certain exceptions, refrain
from changing its method of accounting or its method of tax reporting; (v)
refrain from merging into, consolidating with, or selling its assets to any
other corporation or person, or permitting any other corporation to be merged or
consolidated with it; and (vi) refrain from acquiring all of the assets of any
other corporation or person. The Reorganization Agreement further provides that
Farmers may not declare or pay any dividends or make any distributions other
than regular cash dividends, payable at such times and in amounts consistent
with past practice and not to exceed the per share rate paid in the prior
calendar year; provided, that, if the Merger shall occur prior to the payment of
the regular annual cash dividend of Farmers, Farmers may pay a cash dividend in
an amount equal to the per share rate paid in the prior calendar year, prorated
to the date of the Merger.
 
     In the Reorganization Agreement, Farmers has agreed that it will not,
except with the written consent of First Citizens, directly or indirectly
solicit or encourage, nor will it permit any of its officers, directors,
employees, or agents directly or indirectly to solicit or encourage, including
by way of furnishing information, any inquiries or proposals for a merger,
consolidation, share exchange or similar transaction involving Farmers or for
the acquisition of the stock or all or substantially all of the assets or
business of Farmers, or discuss with or enter into conversations with any person
(other than Farmers' shareholders or employees) concerning any such merger,
consolidation, share exchange or other transaction, other than the Merger;
provided, however, that Farmers may communicate information about any such
proposals or inquiries to its shareholders and to the extent that it is required
to do so in order to reasonably comply with its legal obligations. Farmers has
agreed to promptly notify First Citizens orally (to be confirmed in writing as
soon as practicable thereafter) of all of the relevant details relating to any
inquiries or proposals that it may receive relating to any such matters,
including actions it intends to take with respect to such matters.
 
     In order to induce First Citizens to enter into the Reorganization
Agreement and incur the substantial expenses involved in effectuating the
transactions contemplated thereby, Farmers has further agreed to pay First
Citizens the sum of $500,000 upon First Citizens' demand therefor, in the event
the Farmers shareholders fail to approve the Reorganization Agreement or the
Merger Agreement as a result of Farmers' decision to entertain offers from and
negotiate with a bona fide offeree other than First Citizens.
 
     Pursuant to an Administrative Services Agreement ("Services Agreement")
dated as of September 18, 1997 by and between First Citizens and Farmers, First
Citizens has agreed to provide certain administrative, operational and other
support services to Farmers during the period from September 18, 1997 to the
date of the consummation of the Merger (or earlier termination of the Merger
Agreement) and Farmers has agreed to pay First Citizens the sum of $1,739.40 per
week during such period as compensation for the rendering of such services.
 
     The Services Agreement provides that (i) the specific services to be
performed by First Citizens thereunder must be approved in advance by Farmers'
Board of Directors, (ii) all such services are advisory only and (iii) any
actions taken by Farmers in implementing First Citizens' recommendations will be
taken by Farmers only upon specific authority from, or action by, Farmers'
Board. First Citizens has agreed that in performing services under the Services
Agreement, it will conduct its activities in a manner designed to protect
against the disclosure or misuse of Farmers' proprietary/confidential
information. Each party has agreed to indemnify the other party against any loss
or liability caused by the indemnifying party's negligence or failure to comply
with its obligations under the Service Agreement. The Services Agreement has
been reviewed by the ODFI and the Federal Reserve Board.

EXPENSES OF THE MERGER
 
     Each of First Citizens and Farmers shall bear its own expenses in
connection with the Merger, except that First Citizens shall be responsible for
all expenses incident to obtaining requisite regulatory approvals.
 
OPERATIONS OF FARMERS AFTER THE MERGER
 
     Pursuant to the terms of the Reorganization Agreement and the Merger
Agreement, Farmers Interim Bank shall be merged with and into Farmers and
Farmers shall be the Surviving Bank as of the Effective Time. The Articles of
Incorporation and Code of Regulations of Farmers shall become the Articles of
Incorporation and Code of Regulations of the Surviving Bank until thereafter
duly altered, amended or repealed in accordance with applicable law.
 
     At the Effective Time, the Board of Directors of the Surviving Bank shall
consist of all of the persons who were directors of Farmers immediately prior to
the Effective Time, plus two nominees of First Citizens. Each such director
shall serve for the balance of his term and until his successor is duly elected
and qualified or until his earlier death, resignation or removal in the manner
provided in the Code of Regulations of the Surviving Bank or as otherwise
provided by law. Furthermore, each person who is an officer of Farmers prior to
the Effective Time shall remain an officer of the Surviving Bank. For further
information regarding the directors and officers of First Citizens and the
Surviving Bank, see "INFORMATION WITH RESPECT TO FIRST CITIZENS -- Management."
 
     In addition, each common share of Farmers, par value $20.00 per share,
issued and outstanding immediately prior to the Effective Time shall thereafter
continue to be one common share of the Surviving Bank.
 
     Upon completion of the Merger, the Surviving Bank shall be known as
"Farmers State Bank" and the offices of Farmers will be operated as branches of
the Surviving Bank.
 
ACCOUNTING TREATMENT
 
     The Merger is expected to qualify as a "pooling-of-interests" for
accounting and financial reporting purposes. The pro forma results of this
accounting treatment are shown in the unaudited pro forma financial information
appearing elsewhere in this Proxy Statement/Prospectus. See "PRO FORMA FINANCIAL
INFORMATION."
 
     As noted above, it is a condition to the obligation of First Citizens and
Farmers to consummate the Merger that First Citizens shall have received a
letter from its auditors, Crowe, Chizek and Company LLP, to the effect that the
Merger will qualify as a pooling-of-interests transaction under generally
accepted accounting principles. Among the conditions which must be met in order
for the Merger to qualify for "pooling-of-interests" accounting treatment,
generally accepted accounting principles require that, in the aggregate, no more
than ten percent of the Farmers Common Shares (or 20,000 shares based on 200,000
shares presently outstanding) be held, in the aggregate, by Farmers shareholders
who (i) have exercised dissenters' rights in connection with the Merger and
demanded payment in cash for the value of their Farmers common shares under the
ORC or (ii) receive cash in lieu of fractional shares. In the event such
condition is not met, the Merger would not be consummated unless the condition
was waived by First Citizens and Farmers. Furthermore, in order to qualify for
"pooling-of-interests" accounting treatment, no affiliate of Farmers may reduce
his or her risk relative to the First Citizens Common Shares received in the
Merger until such time as financial results covering at least 30 days of
post-merger combined operations have been published.
 
RESALE OF FIRST CITIZENS COMMON SHARES
 
     No restrictions on the sale or other transfer of the First Citizens Common
Shares issued pursuant to the Merger will be imposed solely as a result of the
Merger, except for restrictions on the transfer of shares issued to any Farmers
shareholder who may be deemed to be an "affiliate" of Farmers for purposes of
Rule 145 under the 1933 Act. Generally, "affiliates" of Farmers would include
officers, directors and significant shareholders of Farmers. The Merger
Agreement requires Farmers to cause persons who could be considered to be
"affiliates" to enter into an agreement with First Citizens to the effect that
the First Citizens Common Shares to be acquired by
 
                                       28
<PAGE>   42
 
such "affiliates" will not be sold, pledged, transferred or otherwise disposed
of except in compliance with the 1933 Act and the rules and regulations
thereunder.
 
     First Citizens Common Shares issued to Farmers shareholders who may be
deemed to be affiliates may be resold only (i) in transactions permitted by Rule
145 promulgated under the 1933 Act, (ii) pursuant to an effective registration
statement, or (iii) in transactions exempt from registration.
 
                  DESCRIPTION OF FIRST CITIZENS COMMON SHARES
 
GENERAL
 
     First Citizens has authorized 10,000,000 Common Shares, without par value,
of which 3,051,504 are issued and outstanding and none are treasury shares. Each
outstanding First Citizens Common Share is duly authorized, validly issued,
fully paid and nonassessable. The holders of First Citizens Common Shares have
one vote per share on each matter on which shareholders are entitled to vote
and, in accordance with Ohio law, cumulative voting rights may be requested in
connection with the election of directors. Directors are elected for staggered,
three year terms. Specifically, the Board is divided into three classes of equal
or near equal number, with the members of one class being elected annually. On
liquidation or dissolution of First Citizens, the holders of First Citizens
Common Shares are entitled to share ratably in such assets as remain after
creditors have been paid. Holders of First Citizens Common Shares have the
preemptive rights described in Section 1701.15 of the ORC. Pursuant to Section
1701.15 of the ORC, no preemptive rights are available in connection with shares
issued or agreed to be issued for considerations other than money, as is the
case in the Merger.
 
     First Citizens' Board of Directors determines whether to declare dividends
and the amount of any dividends declared. Such determinations by the Board of
Directors take into account First Citizens' financial condition, results of
operations and other relevant factors. While management expects to maintain its
policy of paying regular cash dividends, no assurances can be given that any
dividends will be declared, or, if declared, what the amount of such dividends
will be. See "INFORMATION WITH RESPECT TO FIRST CITIZENS -- Market Price of
First Citizens Common Shares."
 
     Fifth Third Bank is the transfer agent and registrar for First Citizens
Common Shares.
 
PROVISIONS RELATING TO BUSINESS COMBINATIONS
 
  Business Combinations
 
     Article SIXTH ("Article SIXTH") of First Citizens' Articles of
Incorporation sets forth certain requirements in connection with the approval or
authorization of any of the following (each, a "Business Combination"): (a) any
merger or consolidation involving First Citizens or any subsidiary
("Subsidiary") of First Citizens; (b) any sale or other disposition of all or a
substantial part of the assets of First Citizens or any Subsidiary; (c) any sale
or other disposition of all of a substantial part of the assets of any entity to
First Citizens or any Subsidiary; (d) any sale or other disposition by First
Citizens or any Subsidiary of any corporation; (e) any recapitalization or
reclassification of First Citizens' securities or other transaction that would
have the effect of increasing the voting power of a Related Person (as defined
below); (f) any liquidation, spin-off, split-up or dissolution of First
Citizens; and (g) any agreement or other arrangement providing for any of the
foregoing.
 
     For purposes of Article SIXTH, "Related Person" generally means any person,
entity or group, including any affiliate or associate thereof, (other than First
Citizens, any wholly-owned Subsidiary and any employee benefit plan sponsored by
First Citizens or any such Subsidiary) that, at the time any Business
Combination is agreed to, authorized or approved, is the beneficial owner of
greater than 10% of the First Citizens Common Shares entitled to vote on such
Business Combination.
 
  Board Considerations
 
     Article SIXTH provides that when evaluating a Business Combination or any
tender or exchange offer, the Board of Directors of First Citizens shall
consider, without limitation: (a) the social and economic effects of the
 
                                       29
<PAGE>   43
 
transaction on First Citizens and its Subsidiaries, employees, customers,
creditors and community; (b) the business and financial conditions and earning
prospects of the acquiring person or persons; and (c) the competence, experience
and integrity of the acquiring person or persons and its or their management.
 
  Shareholder Approval
 
     Article SIXTH provides that the affirmative vote of the holders of not less
than 80% of each class of First Citizens Common Shares entitled to vote on the
transaction shall be required for the approval of any Business Combination in
which a Related Person has an interest (except proportionately as a
shareholder); provided, however, the 80% voting requirement shall not be
applicable if (a) the continuing directors, who at the time constitute at least
a majority of the Board of Directors of First Citizens, have approved the
Business Combination by at least a two-thirds vote or (b) certain conditions
relating to the fairness of the transaction have been satisfied. Pursuant to
Article FIFTH, if the 80% voting requirement is inapplicable, the transaction
under consideration may be authorized by the affirmative vote of the holders of
First Citizens Common Shares entitling them to exercise a majority of the voting
power of the corporation.
 
     Article SIXTH further provides that no amendment of First Citizens'
Articles of Incorporation shall be effective to amend, alter or repeal any of
the provisions of Article SIXTH unless such amendment shall receive the
affirmative vote of the holders of not less than 80% of the First Citizens
Common Shares entitled to vote thereon; provided, however, the 80% voting
requirement shall not be applicable if such amendment shall have been proposed
and authorized by the Board of Directors of First Citizens by the affirmative
vote of at least 2/3 of the continuing directors.
 
                   COMPARATIVE RIGHTS OF FARMERS SHAREHOLDERS
 
     As a consequence of the Merger, shareholders of Farmers will become
shareholders of First Citizens, and their rights as shareholders of First
Citizens will be determined by the ORC and by First Citizens' Articles of
Incorporation and Code of Regulations. In many instances, including pre-emptive
rights, waiver of notice of annual meetings, the capacity to take action without
a meeting, and the availability of indemnification for officers and directors,
the rights of Farmers shareholders, which are currently governed by the Farmers
Articles of Incorporation and the ORC, are substantially the same as the rights
of First Citizens shareholders. The following summary compares certain rights of
the holders of Farmers Common Shares to the rights of holders of First Citizens
Common Shares in areas where those rights are materially different. However,
this summary does not purport to be a complete description of such differences
and is qualified in its entirety by reference to the ORC and the governing
corporate instruments of Farmers and First Citizens.
 
AUTHORIZED AND OUTSTANDING SHARES
 
     Farmers has authorized 200,000 Farmers Common Shares, $20.00 par value, all
of which are currently issued and outstanding. First Citizens has authorized
10,000,000 First Citizens Common Shares, without par value, of which 3,051,504
are currently issued and outstanding. As a result of the Merger, First Citizens
will have up to 4,263,504 First Citizens Common Shares issued and outstanding.
 
NOTICE OF SHAREHOLDER MEETINGS
 
     Notice of a special meeting of the Farmers shareholders must be given to
the Farmers shareholders not less than seven nor more than 60 days before the
date of such meeting. By contrast, notice of a special meeting of the First
Citizens shareholders must be given not less than 10 nor more than 60 days
before the date of such meeting.
 
QUORUM
 
     No particular number of Farmers shareholders is needed to establish a
quorum for a meeting of the Farmers shareholders. A quorum at such meeting
consists of the number of Farmers shareholders present in person or by
 
                                       30
<PAGE>   44
 
proxy. By contrast, a majority of outstanding First Citizens Common Shares
present in person or by proxy is required to constitute a quorum for a meeting
of the First Citizens shareholders.
 
VOTING
 
     Both Farmers shareholders and First Citizens shareholders are entitled to
one vote per share; however, unlike Farmers shareholders, First Citizens
shareholders are entitled to request cumulative voting in the election of
directors.
 
     In most instances, matters submitted to the Farmers shareholders or to the
First Citizens shareholders are decided by a majority of votes cast with respect
thereto. However, pursuant to the default provisions of the ORC, Farmers
shareholders may amend the Farmers Articles of Incorporation, within certain
limits and subject to approval by the Superintendent of the ODFI, and approve
certain business combinations and other change-of-control transactions, by the
affirmative vote of the holders of Farmers Common Shares entitling them to
exercise at least two-thirds of the voting power of the corporation. Further, in
certain instances First Citizens has exercised its right to opt-out of the ORC's
default shareholder voting provisions, such that an 80% affirmative vote is
required for specified shareholder amendments to the First Citizens Articles of
Incorporation and for shareholder approval of certain business combinations. See
"DESCRIPTION OF FIRST CITIZENS COMMON SHARES -- Provisions Relating to Business
Combinations."
 
     A majority of votes cast by Farmers shareholders entitled to vote in the
election of directors is always sufficient to remove a director from the Farmers
Board. A majority of votes cast by First Citizens shareholders qualified to vote
in the election of directors may also be sufficient to remove a director from
the First Citizens Board, subject to two qualifications. First, in the event of
a proposed Business Combination, the removal of a First Citizens director by the
First Citizens shareholders requires the affirmative vote of not less than 80%
of the First Citizens Common Shares entitled to vote with respect to such
removal. Second, a First Citizens director may only be removed by the First
Citizens shareholders if the votes cast against his or her removal would not be
enough to elect one director under the cumulative voting scheme.
 
NOMINATION OF DIRECTORS
 
     With regard to both First Citizens and Farmers, only nominated persons are
eligible for election to their respective boards of directors. Farmers has no
specific requirements for nomination of a person to its Board. By contrast,
First Citizens only recognizes nominations made by or at the direction of the
Board of Directors, or by any shareholder present at a meeting of the First
Citizens shareholders who complies with specified advance notice procedures. In
most instances, to be timely, a shareholder must submit a nomination in writing
to the secretary of First Citizens not less than 14 nor more than 50 days prior
to the meeting of the First Citizens shareholders. However, if First Citizens
fails to provide its shareholders with at least 21 days prior notice of the
meeting, such written nomination need not be submitted until the earlier of (i)
the close of business on the seventh day following notice of the meeting and
(ii) seven days prior to the date of the meeting.
 
NUMBER OF DIRECTORS
 
     The Farmers Board of Directors, which at all times must consist of no fewer
than five directors and have a majority of outside directors, currently consists
of eight directors, five of whom are outside directors. By contrast, the First
Citizens Board of Directors, which at all times must consist of no fewer than
five nor more than 25 directors, but need not have a majority of outside
directors, currently consists of eleven directors, nine of whom are outside
directors. Each of the First Citizens' Board of Directors and the Farmers' Board
of Directors is divided into three classes of approximately equal number, with
each class being elected for staggered three-year terms.

                        PRO FORMA FINANCIAL INFORMATION
 
     The following unaudited pro forma condensed consolidated balance sheet as
of September 30, 1997 and the unaudited pro forma condensed consolidated
statements of income for the nine months ended September 30, 1997 and 1996, and
for the years ended December 31, 1996, 1995 and 1994 have been prepared to
reflect First Citizens' acquisition of Farmers as if the acquisition had
occurred on September 30, 1997 with respect to the balance sheet and as of
January 1 with respect to each of the income statements, in each case giving
effect to the pro forma adjustments described in the accompanying notes. The pro
forma adjustments are based on estimates made for the purpose of preparing these
pro forma financial statements. The actual adjustments to the accounts of First
Citizens will be made based on the underlying historical financial data at the
time of the transaction. First Citizens' management believes that the estimates
used in these pro forma financial statements are reasonable under the
circumstances.
 
     The pro forma condensed consolidated financial information has been
prepared based on the "pooling-of-interests" method of accounting assuming
1,212,000 First Citizens Common Shares will be issued and that no Farmers
shareholders will dissent with respect to the Merger. This information will vary
if any Farmers' shareholders dissent. For a discussion of the
pooling-of-interests method of accounting, see "PROPOSED MERGER -- Accounting
Treatment" and "Other Provisions of the Merger Agreement."
 
     The unaudited pro forma condensed consolidated balance sheet as of
September 30, 1997 is not necessarily indicative of the combined financial
position had the Merger been effective at that date. The unaudited pro forma
condensed consolidated statements of income are not necessarily indicative of
the results of operations that would have occurred had the Merger been effective
at the beginning of the periods indicated, or of the future results of
operations of First Citizens. These pro forma financial statements should be
read in conjunction with the historical financial statements and the related
notes incorporated elsewhere in this Proxy Statement/Prospectus.
 
     No adjustments to the pro forma financial statements were necessary to
conform accounting methods as contemplated by Accounting Principles Board
Opinion No. 16.

improve Farmers' overall financial condition. The MOU specifies various

measures be maintained until such time as the MOU is stayed, modified,
terminated or suspended by the ODFI and the FDIC.
 
                                       43
<PAGE>   57
 
     The MOU requires Farmers to, among other things:
 
          i. Achieve and maintain, through charges to current operating income,
     an adequate valuation reserve for loan losses; conduct a quarterly
     assessment of the loan loss reserve and nonperforming loans; refile Reports
     of Condition and Income for December 31, 1996 and the first three quarters
     of 1997 to reflect an appropriate level of Allowance for Loan and Lease
     Losses; maintain documentation in support of the foregoing; and submit to
     the ODFI and the FDIC a record of the methodology used for determining loan
     loss reserves;
 
          ii. Develop a written plan designed to improve Farmers' position on
     certain loans in excess of $100,000 which are past due on principal or
     interest by 90 days or more;
 
          iii. Prepare and submit to the ODFI and the FDIC for review and
     approval (A) a management plan describing actions to be taken by Farmers'

     supervision of Farmers' affairs, (B) an amended written loan policy
     including the recommendations detailed in the Examination Report, (C)
     written loan review procedures designed to identify and categorize problem
     credits and assess the overall quality of the loan portfolio, (D) an
     amended appraisal policy and procedures consistent with the Examination
     Report and regulatory guidelines, (E) an amended written investment policy
     consistent with regulatory guidelines, (F) an amended interest rate risk
     policy and procedures consistent with the Examination Report and regulatory
     guidelines and (G) quarterly progress reports detailing the actions taken
     to secure compliance with the MOU and the results thereof;
 
          iv. Establish procedures to ensure that (A) Farmers' officers and
     employees are aware of, have access to, and adhere to Farmers' loan policy,
     (B) exceptions to Farmers' loan policy are approved in advance by the Board
     of Directors, and (C) the reasons for any such exceptions are noted in the
     Board minutes and maintained in the obligor's file;
 
          v. Refrain from (A) declaring or paying dividends without the prior
     written approval of the ODFI and the FDIC when Farmers' tier one leverage
     ratio is below 7.5% or (B) extending any additional credit to any borrower
     who is an obligor to Farmers on any extension of credit or portion thereof
     that has been charged-off or classified "substandard," "doubtful," or
     "loss" in the Examination Report or in any subsequent examination report so
     long as such credit remains uncollected, unless the additional extension of
     credit has been authorized in advance by the Farmers Board of Directors in
     accordance with certain standards and supported by certain documentation;
 
          vi. Take all necessary steps consistent with sound banking practices
     to (A) address all violations described in the Examination Report and
     refrain from engaging in such violations in the future, (B) eliminate
     and/or correct problems relating to credit information and collateral
     documentation and ensure proper collection and maintenance of such
     information and documentation in the future, and (C) ensure all
     deficiencies in internal routine and controls, as identified in the
     Examination Report, are eliminated and/or corrected and procedures are
     implemented to maintain a sound system of internal controls;
 
          vii. Establish a Compliance Committee comprised of outside directors
     to monitor compliance with the MOU and written policies and procedures; and
 
          viii. Adopt all plans, policies and procedures required by the MOU and
     fully comply with all of the terms thereof.
 
  Actions Taken in Response to the Memorandum of Understanding
 
     To date, Farmers has taken the following actions in response to the MOU:
 
          i. Formed a Compliance Committee comprised of outside directors to
     monitor compliance with the MOU and Farmers' written policies and
     procedures and engaged Austin Associates to assist in the coordination of
     MOU compliance efforts;
 
          ii. Contracted for and received a detailed loan review from Austin
     Credit Services;
 
                                       44
<PAGE>   58
 
          iii. Increased loan loss reserves consistent with the recommendations
     of the regulatory examiners and Austin Credit Services;
 
          iv. Developed a plan to correct loan documentation deficiencies;
 
          v. Adopted a lending policy which includes a methodology for
     determining future loan loss reserves;
 
          vi. Filed with the ODFI and FDIC restated reports of condition dating
     back to December 31, 1996 reflecting the increases in its loan loss
     reserves and provided the ODFI and FDIC with certain other documents
     relating to the actions described above.
 
     While Farmers intends to continue to fully comply with all of the
provisions of the MOU, there can be no assurance that such compliance will
improve Farmers' overall financial condition or result in a timely modification
or termination of the MOU. Moreover, compliance by Farmers with the provisions
of the MOU will not bar, estop or otherwise prevent the ODFI and/or the FDIC or
any other regulatory agency or department from taking any other action affecting
Farmers or any of its current or former affiliates.

     It is expected that Farmers will declare its normal annual dividend during
the fourth quarter of 1997. Such dividend would be paid prior to the
consummation of the Merger.
 
     Dividends may be declared by Farmers by its Board of Directors out of
surplus. An Ohio bank must generally maintain surplus in an amount which is
equal to the amount of its capital. In addition to other limitations under Ohio
law with respect to the payment of dividends, approval of the Ohio Division of
Financial Institutions is required for the declaration of dividends by an Ohio
bank if the total of all dividends declared by such bank in any year exceeds the
total of its net profits (as defined in Section 1117.02 of the ORC) for that
year combined with its retained net profits for the preceding two years, less
any required transfers to surplus or a fund for the retirement of any preferred
stock or capital securities.
 
     If, in the opinion of the applicable bank regulatory authority, a bank
under its jurisdiction is engaged in an unsafe or unsound practice (which,
depending on the financial condition of the bank, could include the payment
 
                                       45
<PAGE>   59
 
of dividends), such authority may require, after notice and hearing, that such
bank cease and desist from such practice. In addition, the Federal Reserve Board
and the FDIC have issued policy statements which provide that banks should
generally only pay dividends out of current operating earnings. Finally, bank
regulatory authorities have established guidelines with respect to the
maintenance of appropriate levels of capital by a bank under their jurisdiction.
Compliance with standards set forth in such policy statements and guidelines
could limit the amounts which a bank can pay as dividends. For discussions of
the restrictions on the payment of dividends on Farmers Common Shares, see
"INFORMATION WITH RESPECT TO FARMERS -- Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Capital Resources."

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
  Introduction
 
     This discussion is intended to focus on certain financial information
regarding Farmers. The purpose of this discussion is to provide the reader with
a more thorough understanding of the financial statements. This discussion
should be read in conjunction with the financial statements and accompanying
notes contained elsewhere in this Proxy Statement/Prospectus.

     Management of Farmers is not aware of any market or institutional trends,
events or uncertainties that are expected to have a material effect on
liquidity, capital resources or operations except as discussed herein. Also,
management is not aware of any current recommendations by its regulatory
authorities that would have such effect if implemented except as discussed
herein and under the heading "Business" in "Information with Respect to
Farmers".
 
  Overview
 
     The reported results of Farmers are dependent on a variety of factors,
including the general interest rate environment, competitive conditions in the
industry, governmental policies and regulations and conditions in the markets
for financial assets. Net interest income is the largest component of Farmers
'net income, and consists of the difference between income generated on
interest-earning assets and interest expense incurred on interest-bearing
liabilities. Net interest income is primarily affected by the volume, interest
rates and composition of interest-earning assets and interest-bearing
liabilities.
 
     Average Balances and Yields.  The following tables present for the periods
indicated, the total amount of interest income from average interest-earning
assets and the resultant yields, as well as the interest expense on average
interest-bearing liabilities, expressed both in dollars and rates, and the net
interest margin. Net interest margin refers to the net interest income divided
by total interest-earning assets and is influenced by the level and relative mix
of interest-earning assets and interest-bearing liabilities.

  Comparison of Operating Results for Nine Months Ended September 30, 1997 and
1996
 
     Net income was $992,000 for the nine months ended September 30, 1997
compared to $1,084,000 for the comparable period in 1996. Major factors
impacting these results are discussed below.
 
     Net interest income increased by $348,000 for the nine months ended
September 30, 1997 over the same period in 1996. The majority of this increase
comes from interest and fees on loans which increased by $826,000 and is a
direct reflection of management's continuing emphasis on increase loan volume,
primarily in the real estate mortgage area. The increase in loan income was
partly offset by a decline in interest on securities and short-term investments
as maturities of these assets were used to fund loans. Interest expense on
deposits also increased due to a slight shift from savings accounts to higher
rate certificates of deposit and a general increase in the rates being paid on
certificates of deposit.
 
     The provision for loan losses for the first three quarters of 1997 totaled
$695,000 compared to $274,000 in 1996, an increase of $421,000. The increased
provision expense was made in recognition of the continued increase in loans and
also based on the results of an independent loan review which management
contracted to be performed in response to the MOU. See "INFORMATION WITH RESPECT
TO FARMERS -- Business." The loan review results indicated that internal
procedures for loan underwriting and documentation standards had not been
sufficient to keep pace with the rapid expansion in loan volume. As a result,
the credit quality of new loan originations in 1997 has deteriorated and
perfection of Farmers' security interest is not always well documented. Even
though the majority of new loans are secured by residential real estate, which
typically carry a lower risk of loss than other loans, management felt it
prudent to increase the provision for loan losses until the results of recent
improvements in lending procedures have time to become effective. Management has
taken aggressive action to correct lending deficiencies by adopting a new loan
policy, improving the loan approval process, contracting for the assistance of
experienced loan underwriters and by implementing a standardized loan document
preparation system. These improvements are expected to reduce the need for
future large provisions to the allowance for loan losses.
 
     Noninterest income for the first three quarters of 1997 showed no
significant change from the comparable period in 1996.

     Noninterest expense increased by $131,000 in 1997 over 1996 almost entirely
related to increased professional fees for strategic planning consulting
services and acquisition related costs.
 
  Comparison of Operating Results for the Years Ended December 31, 1996 and 1995
 
     Net income of $1,603,000 for the year ended December 31, 1996 increased by
$7,000 or less than 1% from the net income of $1,596,000 reported in 1995. Major
factors which influenced the change from 1995 to 1996 include an increase in net
interest income of $312,000 that was largely offset by an increase in the
provision for loan losses of $285,000 as more fully discussed below.
 
     Net interest income for 1996 was $3,967,000 compared to $3,655,000 in 1995,
an increase of 8.5%. Total interest income increased by $1,041,000, primarily
from loans and taxable investments compared to an increase of $729,000 in
interest expense, primarily interest paid on deposits. The increase in loan
income resulted from continued growth in the loan portfolio with the average
outstanding balance increasing from $45,801,000 in 1995 to $52,924,000 in 1996
while the average yield remained relatively constant at 9.11% in 1996 compared
to 9.05% in 1995. The increase in interest income on taxable investments also
resulted from an increase in the average balance outstanding which was
$67,826,000 in 1996 compared to $62,338,000 in 1995 while the average yield
showed little change. The increase in earning assets was funded by an increase
in interest bearing liabilities, primarily time deposits, which increased from
an average balance of $79,462,000 in 1995 to $92,576,000 in 1996 while overall
deposit average rates remained flat. Farmers has historically attracted deposits
by offering highly competitive rates and in the latter part of 1995 and 1996
aggressively marketed a six-month time deposit account designed to mature
shortly after the end of the year. As a result, Farmers' overall cost of funds
tends to exceed that of other local community banks, negatively impacting
Farmers' net interest margin.
 
     Management periodically evaluates the adequacy of the allowance for loan
loss balance and makes provisions for possible loan losses by a charge to
operations. As previously discussed, Farmers' regulators have required that the
process used by management to evaluate the adequacy of the allowance for loan
losses be improved. The regulators' recommendations, as well as the results of
an independent loan review process completed in October 1997 have been
considered by management in its assessment of Farmers' 1996 and 1995 allowance
balance and related provisions for loan losses. The provision for loan losses
was $365,000 in 1996 compared to $80,000 in 1995, an increase of $285,000. The
increased provision for 1996 is a result of additional allocations of $72,000
for loans considered impaired, an increase in net charge-offs of $98,000 in 1996
and a reflection of the overall increase in the size of the loan portfolio which
increased from $48,074,000 at year end 1995 to $58,830,000 at year end 1996.
Management's evaluation of the adequacy of the allowance is based upon a review
of the existing loan portfolio considering such items as known problem loans,
past loss experience, delinquency trends, changes in the size and composition of
the loan portfolio and current economic conditions and recommendations of its
regulators and the independent loan review process previously discussed.
 
     Statement of Financial Accounting Standards ("SFAS") Nos. 114 and 118 were
effective January 1, 1995 and require recognition of loan impairment. Loans are
considered impaired if full principal or interest payments are not anticipated.
An impaired loan is carried at the present value of expected cash flows
discounted at the loan's effective interest rate or at the fair value of
collateral if the loan is collateral dependent. A portion of the allowance for
loan losses is allocated to impaired loans. The effect of adopting these
standards did not have a material impact on the 1995 or 1996 financial
statements.
 
     Total noninterest income reflected no significant change for 1996 compared
to 1995. Total noninterest expense increased by $23,000 for 1996 over 1995. This
was comprised of a $138,000 reduction in federal deposit insurance premiums
resulting from a change in premium rates by the FDIC which was offset by normal
salary adjustments of approximately 4.3% and modest increases in other operating
costs.
 
     Federal income tax expense amounted to $382,000 in 1996 compared to
$403,000 in 1995 reflecting effective tax rates of 19.2% and 20.2% respectively.
The effective tax rate is less than the statutory federal income tax rate of 34%
due to Farmers' investment in nontaxable municipal investments and marketable
equity securities for which the dividends are partially excluded from tax.

  Asset Quality
 
     Nonperforming loans consist of loans past due 90 days or more and loans for
which the accrual of interest has been discontinued. Nonperforming loans totaled
approximately $1,260,000 or 2.14% of total loans at December 31, 1996, as
compared to $964,000 or 2.01% of total loans at December 31, 1995. The allowance
for loan losses as a percentage of nonperforming loans was 102.6% and 101.9% at
year end 1996 and 1995, respectively.
 
     The following table sets forth nonaccrual, past due and restructured loans

     Gross interest income that would have been recorded on nonaccrual loans for
the year ending December 31, 1996 if the loans had been current in accordance
with their original terms totalled approximately $42,000. The interest income
actually reflected in earnings for 1996 on nonaccrual loans was approximately
$57,000.
 
     Management evaluates loans that are 90 days or more past due to determine
if they should be placed on nonaccrual status. Factors considered by management
include the estimated value of collateral, if any, and other resources of the
borrower that may be available to satisfy the delinquency.

  Comparison of September 30, 1997 to December 31, 1996 Financial Condition
 
     Total assets as of September 30, 1997 increased by only $2,729,000 or 1.8%
over the balance at December 31, 1996. However, the composition of assets
reflects a more significant change.
 
     Total loans increased by $9,398,000 or 16.0% for the nine months ended
September 30, 1997, reflective of management's continuing emphasis on increasing
Farmers' lending activities in its local market area. Within the various loan
categories, commercial and agricultural loans increased by $2,135,000 or 10.7%
and real estate mortgage loans increased by $8,088,000 or 23.8%. The rapid
increase in volume of loans originated over the last couple years has been
partially the result of management's application of less stringent loan
documentation and underwriting standards than some other lenders in the local
market area. As discussed earlier, a recently completed independent review of
loans originated in 1996 and 1997 indicated that credit quality and
documentation procedures have deteriorated. In recognition of this
deterioration, management elected to increase the allowance for loan losses in
September to a balance of $1,900,000. The allowance for loan losses represents
2.8% of total loans at September 30, 1997 compared to a balance of $1,293,000 or
2.2% of total loans at December 31, 1996. Management has also adopted a new loan
policy, implemented new procedures for the approval of loans and is in the
process of implementing an automated loan document preparation system, all with
the goal of improving loan underwriting and documentation standards. These new
policies and procedures may also have the effect of slowing future increases in
loan volumes.
 
                                       52
<PAGE>   66
 
     The increase in loans was funded by the sale and maturity of securities.
Securities available for sale declined to $47,661,000 at September 30 1997
compared to $54,850,000 at December 31, 1996. The change occurred primarily in
the category of U.S. government and agency securities. Securities held to
maturity also declined from $33,831,000 at December 31, 1996 to $32,178,000 at
September 30, 1997. The rapid shift from securities to loans is not expected to
continue since as noted above, loan growth is expected to slow. The portfolio of
securities available for sale includes equity securities with an original cost
of $3,508,000 and an estimated fair value of $5,844,000 at September 30, 1997,
reflecting net appreciation in value of $2,336,000. This compares to net
appreciation on equity securities of $1,654,000 at December 31, 1996. The
increase in value is attributable to the general increase in the stock market
and the value of these investments can change quickly based on factors outside
of management's control.
 
     No significant changes occurred in the area of deposit liabilities or other
liabilities of Farmers for the period September 30, 1997 compared to December
31, 1996.
 
     Total shareholders' equity increased by $1,694,000 from December 31,1996 to
a total of $15,955,000 at September 30, 1997. The increase reflects earnings of
$992,000 and an increase in the value of securities available for sale, net of
tax effect, of $702,000. Total shareholders' equity was 10.2% of total assets at
September 30, 1997 compared to 9.3% at December 31, 1996.
 
  Comparison of December 31, 1996 and 1995 Financial Condition
 
     Total assets were $153,131,000 at December 31, 1996 compared to
$142,757,000 at December 31, 1995 representing an increase of 7.3%. Those
balance sheet categories reflecting significant changes including securities
available for sale, total loans and interest bearing deposits are discussed
below.
 
     Securities available for sale increased by $2,691,000 or 5.2% in 1996
resulting from additional purchases of U.S. Treasury and agency issues. The
category of securities available for sale includes securities issued by the U.S.
Treasury or U.S. Government agencies, mortgage backed securities issued or
guaranteed by FNMA or FHLMC and marketable equity securities representing 63.2%,
27.3% and 9.5% of the available for sale portfolio respectively. Securities
available for sale are carried on the balance sheet at estimated fair value
which exceeded amortized cost by $1,275,000 (net) at year end 1996 compared to
net appreciation of $1,120,000 at year end 1995. The increase in net
appreciation relates to increases in the estimated fair value of equity
securities.
 
     Total loans increased by $10,756,000 or 22.4% in 1996 representing
continuing efforts of management to expand lending activities. Loans are
originated by salaried loan officers. The majority of the increase occurred in
the real estate mortgage loan category which represented primarily loans secured
by 1 to 4 family residences in Farmers' primary market area. Real estate
mortgages at December 31, 1996 represented 57.8% of total loans compared to
53.7% at year end 1995. Commercial and agriculture loans represented 33.9% of
total loans at December 31, 1996 compared to 39.5% in 1995. The remainder of the
portfolio consisted of consumer loans, real estate construction loans and other
loans. Agriculture loans including loans to farmers and other business closely
related to the agriculture industry totaled approximately $7,826,000 and
$8,282,000 at December 31, 1996 and 1995 representing 13.3% and 17.2% of total
loans, respectively. Farmers does not sell loans in the secondary market and
generally does not purchase or sell significant participations in loans.
 
     The increase in assets discussed above was funded largely by an increase of
$9,146,000 (or 7.6%) in interest bearing time deposits in 1996. Farmers has
typically attracted deposits by offering interest rates that exceed the rates
paid by other local financial institutions. In addition, management has been
successful in marketing a six-month time deposit which is scheduled to mature
after the calendar year end. At December 31, 1996 54.6% of Farmers' total time
deposits had a maturity of one year or less.
 
  Capital Resources
 
     Total shareholders' equity at December 31, 1996 was $14,261,000 an increase
of $1,505,000 or 11.8% from total shareholders' equity of $12,756,000 at
December 31, 1995. The increase reflected earnings of $1,603,000, dividends paid
of $280,000 and an increase in the unrealized gain on securities available for
sale, net of tax effects, of $182,000.

     Banking regulations have established minimum capital requirements for banks
including riskbased capital ratios and leverage ratios. As of December 31, 1996,
these capital regulations require banks to maintain minimum total risk-based
capital ratios of 8%, Tier-1 capital (as defined) to risk weighted assets of 4%
and Tier-1 capital to average assets of 4%. To be considered well capitalized
these requirements become 10%, 6% and 5% respectively. As reflected in Note 12
of the accompanying financial statements, Farmers' actual capital ratios at
December 31, 1996 were total capital to risk weighted assets of 19.1%, Tier-1
capital to risk weighted assets of 17.8% and Tier-1 capital to average assets of
9.1%. All of these ratios were above the requirements to be considered well
capitalized.
 
  Liquidity
 
     Liquidity management for Farmers centers around the assurance that funds
are available to meet the loan and deposit needs of its customers, and Farmers'
other financial commitments.
 
     Cash and noninterest bearing deposits with banks, federal funds sold and
other short-term investments totaled $4,464,000 December 31, 1996. These assets
provide the primary source of liquidity for Farmers. In addition, management has
designated a substantial portion of the investment portfolio ($54,850,000) as
available for sale to provide an additional source of liquidity.
 
     A standard measure of liquidity is the relationship of loans to deposits.
Lower ratios indicate greater liquidity. At December 31, 1996 and 1995 the ratio
of total loans to deposits was 43.5% and 37.9% respectively, considered an
acceptable level of liquidity by management.
 
  Asset/Liability Management
 
     Asset/liability management is the process of monitoring Farmers' exposure
to changes in interest rates. The primary measure of interest rate risk exposure
is Farmers' "gap," or the difference between interest rate sensitive assets and
liabilities that mature of reprice within similar periods of time. A financial
institution like Farmers', with a negative interest rate sensitivity gap, has an
amount of interest-bearing liabilities maturing or otherwise repricing within
the period which exceeds the amount of interest-bearing assets maturing of
otherwise repricing within the same period. In a rising interest rate
environment, a financial institution with a negative interest sensitivity gap
generally will experience greater increases in the cost of its interest bearing
liabilities than in the yield on its earning assets. Conversely, in a falling
interest rate environment the cost of interest bearing liabilities will
generally decline more quickly than the yield on earning assets.
 
     The table below provides a measure of Farmers' interest rate sensitivity at
December 31, 1996. The amount of assets or liabilities shown which reprice or
mature within a period were determined based on the contractual terms of the
asset or liability. Savings, NOW and money market demand deposit accounts
reprice at management's discretion and therefore are included in the amount
repricing within three months. This table may not reflect the actual impact on
Farmers of changes in interest rates because the repricing of various categories
of rate sensitive assets and liabilities are subject to other factors such as
competition, customer preference, and management influence.

  Impact of Inflation and Changing Prices
 
     The financial statements and related data presented herein have been
prepared in accordance with generally accepted accounting principles, which
require the measurement of financial position and results of operations
primarily in terms of historical dollars without considering changes in the
relative purchasing power of money over time due to inflation. Unlike most
industrial companies, virtually all of the assets and liabilities of Farmers are
monetary in nature. As a result, interest rates have a more significant impact
on a financial institution's performance than the effects of general levels of
inflation. Interest rates do not necessarily move in the same direction or in
the same magnitude as the prices of goods and services.
 
CERTAIN STATISTICAL INFORMATION WITH RESPECT TO FARMERS

consummation of the Merger, the total number and percentage of Farmers Common
Shares beneficially owned by each director of Farmers, each executive officer of
Farmers, and each owner of more than 5% of the outstanding Farmers Common Shares

will be exercised by Farmers shareholders and that all 200,000 outstanding
Farmers Common Shares will be exchanged for First Citizens Common Shares in the
Merger.

                                 LEGAL OPINIONS
 
     A legal opinion has been rendered by Squire, Sanders & Dempsey L.L.P. to
the effect that the issuance of the shares of First Citizens Common Shares
offered hereby has been duly authorized by First Citizens and that the Shares,
when issued in accordance with the Merger Agreement, will be duly issued and
outstanding and fully paid and nonassessable. A tax opinion is to be rendered
prior to the Effective Time by Werner & Blank Co., L.P.A. substantially to the
effect that (i) the Merger will constitute a "Statutory Merger" within the
meaning of Section 368(a)(1)(A) and (a)(2)(E) of the Internal Revenue Code of
1986, as amended (the "Code") and Farmers Interim Bank, Farmers and First
Citizens will each be a "party to a reorganization" within the meaning of
Section 368(b) of the Code, (ii) no gain or loss will be recognized by Farmers
as a result of the Merger, (iii) no gain or loss will be recognized by Farmers
shareholders who exchange their Farmers Common Shares solely for First Citizens
Common Shares in the Merger, (iv) the federal income tax basis of the First
Citizens Common Shares received by Farmers shareholders in the Merger will be
the same as the federal income tax basis in the Farmers Common Shares exchanged
therefor, respectively, (v) the holding period for the First Citizens Common
Shares received by each Farmers shareholders in the Merger will include the
period during which the Farmers Common Shares exchanged therefor were held,
provided that the exchanged Farmers Common Shares were held as capital assets by
such Farmers shareholder on the date of the exchange, and (vi) the payment of
cash in lieu of fractional shares for the purpose of mechanically rounding off
the fractions resulting from the exchange will, in each instance, constitute a
distribution not essentially equivalent to a dividend within the meaning of
Section 302(b)(1) of the Code, and therefore, the amount received will be
treated as a distribution in full payment in exchange for such Farmers
shareholder's fractional share of interest under Section 302(a) of the Code.
 
                                INDEMNIFICATION
 
     The Articles of Incorporation of First Citizens provide that First Citizens
shall have the power to indemnify its present and past directors, officers,
employees and agents, and such other persons as it shall have powers to
indemnify, to the full extent permitted under, and subject to the limitations
of, Title 17 of the ORC. Such Articles of Incorporation further provide that
First Citizens may, upon the affirmative vote of a majority of its Board of
Directors, purchase insurance for the purpose of indemnifying its directors,
officers, employees and agents to the extent that such indemnification is
allowed by the Articles of Incorporation.
 
     Insofar as indemnification for liabilities arising under the 1933 Act may
be permitted to directors, officers or persons controlling First Citizens
pursuant to the foregoing provisions, First Citizens has been informed that in
the opinion of the Commission such indemnification is against public policy as
expressed in the 1933 Act and is therefore unenforceable.

                         REPORT OF INDEPENDENT AUDITORS
 
Shareholders and Board of Directors
The Farmers State Bank
New Washington, Ohio
 
We have audited the accompanying balance sheets of The Farmers State Bank as of
December 31, 1996 and 1995, and the related statements of income, changes in
shareholders' equity and cash flows for the years then ended. 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 financial position of The Farmers State Bank as of
December 31, 1996 and 1995, and the results of its operations, and its cash
flows for the years then ended, in conformity with generally accepted accounting
principles.

                             THE FARMERS STATE BANK
 
                         NOTES TO FINANCIAL STATEMENTS
 
           SEPTEMBER 30, 1997 AND 1996 AND DECEMBER 31, 1996 AND 1995
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The following is a summary of the accounting policies adopted by The
Farmers State Bank which have a significant effect on the financial statements.
All information presented as of September 30, 1997 and for the nine-month
periods ending September 30, 1997 and 1996 is unaudited.
 
     NATURE OF OPERATIONS:  The Bank is primarily engaged in the business of
commercial and retail banking in Crawford County, Ohio and the communities of
Richwood and Green Camp, Ohio. The Bank provides a broad range of banking and
financial services, including accepting demand, savings and time deposits and
granting commercial, real estate and consumer loans.
 
     USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS:  In preparing
financial statements, management must make estimates and assumptions. These
estimates and assumptions affect the amounts reported for assets, liabilities,
revenue, and expenses, as well as the disclosures provided. Future results could
differ from the current estimates. Estimates that are more susceptible to change
in the near term include the collectibility of loans, the fair values of
financial instruments and the status of contingencies.
 
     CASH:  For purposes of reporting cash flows, the Bank considers "cash and
cash equivalents" to include cash on hand and demand deposits with financial
institutions. The Bank reports net cash flows for federal funds sold, customer
loan transactions, deposit transactions, securities sold under agreements to
repurchase and other short-term borrowings. For the nine months ended September
30, 1997 and 1996 and the years ended December 31, 1996, and 1995, the Bank paid
interest of $5,550,348, $5,261,601, $6,521,156 and $5,319,792, respectively, and
income taxes of $339,500, $327,160, $381,720, and $402,897. Noncash transactions
included transfers from loans to other real estate owned totaling $82,000 in the
nine months ended September 30, 1997.
 
     SECURITIES:  The Bank classifies securities into held-to-maturity and
available-for-sale categories. Held-to-maturity securities are those the Bank
has the positive intent and ability to hold to maturity and are reported at
amortized cost. Available-for-sale securities are those the Bank may sell if
needed for liquidity, asset-liability management, or other reasons even if
management does not have a present intention of such a sale. Equity securities
that have a readily determinable fair value are also classified as available for
sale. Available-for-sale securities are reported at fair value, with unrealized
gains or losses included as a separate component of equity, net of tax.
 
     Realized gains or losses are determined based on the amortized cost of the
specific security sold. Interest and dividend income, adjusted by amortization
of purchase premium or discount, is included in earnings.
 
     LOANS RECEIVABLE:  Loans receivable that management has the intent and
ability to hold for the foreseeable future or until maturity or pay-off are
reported at their outstanding principal balance, adjusted for any charge-offs
and any deferred fees or costs on originated loans and unamortized premiums or
discounts on purchased loans. Mortgage loans originated and intended for sale in
the secondary market are carried at the lower of cost or estimated market value
in the aggregate. Net unrealized losses are recognized through a valuation
allowance by charges to income. Effective January 1, 1996, the Bank adopted the
provisions of SFAS No. 122, "Accounting for Mortgage Servicing Rights." This
statement requires companies to recognize, as separate assets, rights to service
mortgage loans for others, however those servicing rights are acquired. A
company that acquires mortgage servicing rights through either purchase or
origination of mortgage loans and sells or securitizes those loans with
servicing rights retained should allocate the total cost of the mortgage loans
to mortgage servicing rights and to loans (without the mortgage servicing
rights) based on their relative fair values. Mortgage servicing rights recorded
as a separate asset will be amortized in proportion to, and over the period of,
estimated net servicing income. This statement has no impact on the financial
statements at the present time because the Bank is not currently involved in
selling loans with servicing rights retained.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

     ALLOWANCE FOR LOAN LOSSES:  The allowance for loan losses is increased by
charges to income and decreased by charge-offs, net of recoveries. Management's
periodic evaluation of the adequacy of the allowance is based on past loan loss
experience, known and inherent risks in the portfolio, adverse situations that
may affect the borrower's ability to repay, the estimated value of any
underlying collateral, and current economic conditions.
 
     Statement of Financial Accounting Standards Nos. 114 and 118 were effective
January 1, 1995 and required recognition of loan impairment. Loans are
considered impaired if full principal or interest payments are not anticipated.
Impaired loans are carried at the present value of expected future cash flows
discounted at the loan's effective interest rate or at the fair value of
collateral if the loan is collateral dependent. A portion of the allowance for
loan losses is allocated to impaired loans. The effect of adopting these
standards is included in the 1995 provision for loan losses and was not
material.
 
     Management analyzes commercial and commercial real estate loans on an
individual basis and classifies a loan as impaired when an analysis of the
borrower's operating results and financial condition indicates that underlying
cash flows are not adequate to meet its debt service requirements. Often this is
associated with a delay or shortfall in payments of 30 days or more.
Smaller-balance homogeneous loans are evaluated for impairment in total. Such
loans include residential first mortgage loans secured by one- to four-family
residences, residential construction loans, consumer automobile, boat, home
equity and credit card loans with balances less than $200,000. In addition,
loans held for sale and leases are excluded from consideration as impaired.
Loans are generally moved to nonaccrual status when 90 days or more past due.
These loans are often also considered impaired. Impaired loans, or portions
thereof, are charged off when deemed uncollectible. The nature of disclosures
for impaired loans is considered generally comparable to prior nonaccrual loans
and nonperforming and past due asset disclosures.
 
     INTEREST AND FEES ON LOANS:  Interest on loans is accrued over the term of
the loan based on the principal outstanding. Management reviews loans delinquent
90 days or more to determine if interest accrual should be discontinued. Under
SFAS No. 114, as amended by SFAS No. 118, the carrying value of impaired loans
is periodically adjusted to reflect cash payments, revised estimates of future
cash flows, and increases in the present value of expected cash flows due to the
passage of time. Cash payments representing interest income are reported as such
and other cash payments are reported as reductions in carrying value. Increases
or decreases in carrying value due to changes in estimates of future payments or
the passage of time are reported as reductions or increases in bad debt expense.
 
     Loan fees and certain direct costs in the origination of loans are deferred
and amortized over the contractual lives of the related loans as an adjustment
of yield using the interest method.
 
     PREMISES AND EQUIPMENT:  Premises and equipment are stated at cost less
accumulated depreciation. Depreciation is computed using both straight-line and
accelerated methods over the estimated useful life of the asset. These assets
are reviewed for impairment under SFAS No. 121 when events indicate the carrying
amount may not be recoverable. Maintenance and repairs are expensed and major
improvements are capitalized.
 
     OTHER REAL ESTATE:  Real estate owned, other than that used in the normal
course of business, is included in other assets at fair value less estimated
costs to sell. Any reduction from carrying value of the related loan to fair
value at the time of acquisition is accounted for as a loan loss. Any subsequent
reduction in fair value is recognized in a valuation allowance by charges to
income. Other real estate owned included in other assets totaled approximately
$82,000 at September 30, 1997. The Bank did not own any other real estate at
December 31, 1996 and 1995.
 
     INCOME TAXES:  The Bank follows the liability method in accounting for
income taxes. The liability method provides that deferred tax assets and
liabilities are recorded at enacted tax rates based on the difference

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 9 -- PENSION PLANS
 
     The Bank maintains a fully insured defined benefit pension plan covering
substantially all employees. Participants are fully vested after 7 years of
participation. The normal retirement benefit is equal to 20% of the average
monthly compensation. Monthly benefits are reduced proportionately for each
month of service less than 300 at the normal retirement date.
 
     The Bank funds all pension costs through the purchase of retirement income
insurance and retirement annuity policies.
 
NOTE 10 -- COMMITMENTS, CONTINGENCIES AND OFF-BALANCE SHEET RISK
 
     The Bank is party to financial instruments with off-balance-sheet risk in
the normal course of business to meet financing needs of their customers. These
include commitments to make or purchase loans, undisbursed lines of credit and
letters of credit. The Bank's exposure to credit loss in the event of
nonperformance by the other party to the financial instrument is represented by
the contractual amount of those instruments. The Bank follows the same credit
policy to make such commitments as is used for loans recorded on the balance
sheet. Since many commitments to make loans expire without being used, the
amount does not necessarily represent future cash commitments. Collateral
obtained relating to the commitments is determined using management's credit
evaluation of the borrower and may include real estate, vehicles, business
assets, deposits and other items. The Bank does make fixed rate loan commitments
for short periods of time. However, such commitments were immaterial as of and
for the nine months ending September 30, 1997 and the years ending December 31,
1996 and 1995.
 
     Commitments to extend credit and letters of credit approximated the

     In the normal course of business, the Bank is involved in various legal
actions but, in the opinion of management and its legal counsel, ultimate
disposition of such matters is not expected to have a material adverse effect on
the financial statements.
 
NOTE 11 -- RESTRICTIONS ON RETAINED EARNINGS
 
     Payment of dividends by the Bank is subject to restrictions by its
regulatory agencies. These restrictions generally limit dividends to the current
and prior two years retained earnings as defined by the regulations, and
dividends may not reduce capital levels below minimum regulatory requirements.
In addition, as more fully discussed below, the Bank must obtain prior approval
of its regulators before declaring any dividend that would reduce the Tier-1
leverage ratio (as defined) below 7.5%. Under the most restrictive of these
requirements, the Bank estimates that retained earnings available for payment of
dividends approximates $2,386,000 at December 31, 1996.

NOTE 12 -- REGULATORY CAPITAL REQUIREMENTS
 
     The Bank is subject to various regulatory capital requirements administered
by the federal banking agencies. Failure to meet minimum capital requirements
can initiate certain mandatory and possibly additional discretionary actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of assets, liabilities and
certain off-balance-sheet items as calculated under regulatory accounting
practices. The Bank's capital amounts and classification are also subject to
qualitative judgments by the regulators about components, risk weightings and
other factors.
 
     Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier-I capital (as defined in the regulations) to
risk-weighted assets (as defined) and of Tier-I capital (as defined) to average
assets (as defined).
 
     As of September 30, 1997, the most recent notification from its primary
regulator categorized the Bank as well capitalized under the regulatory
framework for prompt corrective action. To be categorized as "well capitalized,"
the Bank must maintain minimum total risk-based, Tier-I risk-based, and Tier-I
leverage ratios as set forth in the table below. Management believes that no
conditions or events since that notification have changed the institution's
category.
 
     At September 30, 1997, December 31, 1996 and 1995, the Bank's actual
capital levels and minimum required levels were (dollar amounts in thousands):

</TABLE>
 
     For purposes of the above disclosures of estimated fair value, the
following assumptions were used. Estimated fair value for cash and due from
banks and federal funds sold is considered to approximate cost. Estimated fair
value of securities is based on quoted market values for the individual
securities or equivalent securities. Fair value for loans was estimated for
portfolios of loans with similar financial characteristics. For adjustable rate
loans which reprice at least annually and for fixed rate commercial loans with
maturities of six months or less which possess normal risk characteristics,
carrying value is determined to be fair value. Fair value of other types of
loans (including adjustable rate loans which reprice less frequently than
annually and fixed rate term loans or loans which possess higher risk
characteristics) is estimated by discounting future cash flows using the current
rates at which similar loans would be made to borrowers with similar credit
ratings and for similar anticipated maturities. Fair value for nonaccrual loans
is based on recent appraisals of the collateral or, if appropriate, using
estimated discounted cash flows. Fair value of core deposits, including demand
deposits, savings accounts and certain money market deposits, is the amount
payable on demand. Fair value of fixed-maturity certificates of deposit is
estimated using the rates offered at December 31, 1996 and 1995 for deposits of
similar remaining maturities. Estimated fair value does not include the benefit
that results from low-cost funding provided by the deposit liabilities compared
to the cost of borrowing funds in the market. Fair value of accrued interest and
other borrowings, consisting of securities sold under agreements to repurchase
and U.S. Treasury interest-bearing demand notes payable, is determined to be the
carrying amount since these financial instruments generally represent
obligations which are due on demand. The fair value of unrecorded commitments
at, December 31, 1996 and December 31, 1995 is not material.
 
     While the estimates of fair value are based on management's judgment of the
most appropriate factors, no assurance can be made that were the Bank to have
disposed of such items at December 31, 1996 or December 31, 1995, estimated fair
values would necessarily have been achieved at these dates, since market values
may differ depending on various circumstances. Estimated fair values at,
December 31, 1996 and December 31, 1995 should not necessarily be considered to
apply at subsequent dates.
 
     Other assets and liabilities of the Bank may have value but are not
included in the above disclosures. Also, nonfinancial instruments typically not
recognized in these financial statements nevertheless may have value, but

NOTE 14 -- SUBSEQUENT EVENTS, OTHER REGULATORY MATTERS
 
     Farmers is subject to regulation by the Ohio Division of Financial
Institutions (ODFI) and the Federal Deposit Insurance Corporation (FDIC).
Pursuant to a Memorandum of Understanding dated October 31, 1997 by and among
Farmers, the ODFI and the FDIC (the "MOU"), Farmers has agreed to comply with
certain directives which are intended to correct operational deficiencies
identified in the ODFI's March 14, 1997 Examination Report (the "Examination
Report") and improve Farmers' overall financial condition. The MOU specifies
various deadlines (generally ranging from 10 to 90 days from the date of the
MOU) for the implementation of certain corrective measures and requires that
such measures be maintained until such time as the MOU is stayed, modified,
terminated or suspended by the ODFI and the FDIC.
 
     The MOU requires Farmers to, among other things:
 
          Achieve and maintain an adequate valuation reserve for loan losses;
     conduct a quarterly assessment of the loan loss reserve and nonperforming
     loans; refile Reports of Condition and Income for December 31, 1996 and the
     first three quarters of 1997 to reflect an appropriate level of Allowance
     for Loan and Lease Losses; maintain documentation in support of the
     foregoing; and, submit to the ODFI and the FDIC a record of the methodology
     used for determining loan loss reserves.
 
          Develop a written plan designed to improve Farmers' position on
     certain loans in excess of $100,000 which are past due on principal or
     interest by 90 days or more.
 
          Prepare and submit to the ODFI and the FDIC for review and approval
     (A) a management plan describing actions to be taken by Farmers' Board of
     Directors to strengthen management and improve the Board's supervision of
     Farmers' affairs, (B) an amended written loan policy including the
     recommendations detailed in the Examination Report, (C) written loan review
     procedures designed to identify and categorize problem credit and assess
     the overall quality of the loan portfolio, (D) an amended approval policy
     and procedures consistent with the Examination Report and regulatory
     guidelines, (E) an amended written investment policy consistent with
     regulatory guidelines, (F) an amended interest risk policy and procedures
     consistent with the Examination Report and regulatory guidelines, and (G)
     quarterly progress reports detailing the actions taken to secure compliance
     with the MOU and the results thereof.
 
          Establish procedures to ensure that (A) Farmers' officers and
     employees are aware of, have access to, and adhere to Farmers' loan policy,
     (B) exceptions to Farmers' loan policy are approved in advanced by the
     Board of Directors, and (C) the reasons for any such exceptions are noted
     in the Board minutes and maintained in the obligor's file.
 
          Refrain from (A) declaring or paying dividends without the prior
     written approval of the ODFI and the FDIC when Farmers' Tier-1 leverage
     ratio is below 7.5% or (B) extending any additional credit to any borrower
     who is an obligor to Farmers on any extension of credit or portion thereof
     that has been charged-off or classified "substandard," "doubtful" or "loss"
     in the Examination Report or in any subsequent examination report so long
     as such credit remains uncollected, unless the addition extension of credit
     has been authorized in advanced by the Farmers Board of Directors in
     accordance with certain standards and supported by certain documentation.
 
          Take all necessary steps consistent with sound banking practices to
     (A) address all violations described in the Examination Report and refrain
     from engaging in such violations in the future, (B) eliminate and/or
     correct problems relating to credit information and collateral
     documentation and ensure proper collection and maintenance of such
     information and documentation in the future, and (C) ensure all
     deficiencies in

     internal routine and controls, as identified in the Examination Report, are
     eliminated and/or corrected and procedures are implemented to maintain a
     sound system of internal controls.
 
          Establish a Compliance Committee comprised of outside directors to
     monitor compliance with the MOU and written policies and procedures.
 
          Adopt all plans, policies and procedures required by the MOU and fully
     comply with all of the terms thereof.
 
     Management is in the process of implementing corrective actions to comply
with provisions of the MOU. The evaluation of the adequacy of the allowance for
loan losses has been completed and the results have been considered in the
preparation of these accompanying financial statements. Management therefore
believes that the Allowance for Loan Losses at December 31, 1996 and 1995 is
adequate to provide for known and inherent risk of loss.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     This is an AGREEMENT dated July 3, 1997, between First Citizens Banc Corp.
(hereinafter called "First Citizens") and The Farmers State Bank (hereinafter
called "Farmers").
 
                                  WITNESSETH:
 
     First Citizens is a corporation duly organized under the laws of the State
of Ohio. Its principal office is located at 100 East Water St., Sandusky, Ohio.
As of the date hereof, First Citizens had authorized capital stock consisting of
10,000,000 shares of common stock, without par value ("First Citizens Common
Shares") of which a total of 3,051,504 shares are issued and outstanding and
none are shares of treasury stock owned by First Citizens. First Citizens owns
all of the outstanding capital stock of The Castalia Banking Company, The
Citizens Banking Company, R. A. Reynolds Appraisal Service, Inc. and SCC
Resources, Inc. (hereinafter referred to as the "Subsidiaries").
 
     Farmers is an Ohio state banking corporation duly organized under the laws
of the State of Ohio. Its principal office is located at 102 S. Kibler St., New
Washington, Crawford County, Ohio. As of the date hereof, Farmers has authorized
capital stock consisting of 200,000 authorized shares of common stock, $20 par
value per share ("Farmers Common Stock"), all of which shares are issued and
outstanding and none are shares of treasury stock owned by Farmers.
 
     At least a majority of the entire Board of Directors of First Citizens and
at least a majority of the entire Board of Directors of Farmers, respectively,
have approved the entering into of this Agreement and have authorized the
execution and delivery of this Agreement. The Boards of Directors of First
Citizens and Farmers have determined that it is in the best interests of their
respective corporations and Stockholders that Farmers become a wholly owned
subsidiary corporation of First Citizens. After the execution of this Agreement,
First Citizens will undertake to cause the formation of a new banking
corporation to be organized under the laws of the State of Ohio ("New Bank"),
and thereafter First Citizens and Farmers will cause, subject to the terms and
conditions set forth in this Agreement, the merger of New Bank with and into
Farmers, in accordance with the terms set forth in the Merger Agreement attached
hereto and designated Appendix A (the "Merger Agreement"). From and after the
time the merger of Farmers and New Bank shall become effective, (the "Merger")
and as and when required by this Agreement and the Merger Agreement, First
Citizens will issue its Common Shares in exchange for all of the issued and
outstanding shares of Farmers Common Stock.
 
     In consideration of mutual covenants and agreements herein contained, First
Citizens and Farmers hereby make this Agreement and prescribe the terms and
conditions of the Merger and the mode of carrying the Merger into effect as
follows:
 
          1. Formation of New Bank.  As soon as practicable after the date
     hereof, First Citizens shall commence and proceed with due diligence in the
     formation of the New Bank, all of the outstanding shares of which will be
     acquired by First Citizens prior to the merger of Farmers and the New Bank.
     The New Bank will merge with and into Farmers as the surviving bank
     corporation thereof, pursuant to the Merger Agreement. Upon consummation of
     the Merger, each share of Farmers Common Stock, (other than Dissenter
     Shares, as defined in Section 5) shall be converted into the right to
     receive 6.5 duly authorized, validly issued, fully paid and non-assessable
     First Citizens Common Shares, in accordance with the provisions regarding
     the exchange of shares set forth in the Merger Agreement.
 
          2. The Merger Agreement.  Promptly following the commencement of the
     corporate existence of the New Bank, Farmers and First Citizens shall enter
     into, and First Citizens shall cause the New Bank to enter into, the Merger
     Agreement.
 
          3. Discussions with Others; Other Offers.  On and after the date
     hereof, except with the written consent of First Citizens, Farmers shall
     not directly or indirectly solicit or encourage (nor shall Farmers permit
     any of its officers, directors, employees or agents directly or indirectly
     to solicit or encourage), including by way of furnishing information, any
     inquiries or proposals for a merger, consolidation, share exchange or
     similar transaction involving Farmers or for the acquisition of the stock
     or all or substantially all
 
                                       A-4
<PAGE>   101
 
     of the assets or business of Farmers, or discuss with or enter into
     conversations with any person, other than Farmers stockholders or
     employees, concerning any such merger, consolidation, share exchange,
     acquisition or other transaction, other than the share exchange with First
     Citizens; provided, however, that Farmers may communicate information about
     any such proposals or inquiries to its stockholders if and to the extent
     that it is required to do so in order to reasonably comply with its legal
     obligations. Farmers will promptly notify First Citizens orally (to be
     confirmed in writing as soon as practicable thereafter) of all of the
     relevant details relating to any inquiries or proposals that it may receive
     relating to any such matters, including actions it intends to take with
     respect to such matters.
 
          In order to induce First Citizens to enter into this Agreement and
     incur the substantial expenses involved in effectuating the transactions
     contemplated herein, Farmers agrees and does hereby promise to pay to First
     Citizens the sum of $500,000, upon First Citizens' demand therefor, in the
     event that the Farmers stockholders fail to approve this Agreement or the
     Merger Agreement as a result of Farmer's decision to entertain offers from
     and negotiate with a bona fide offeree other than First Citizens.
 
          4. Undertakings of the Parties.  First Citizens and Farmers further
     covenant and agree as follows:
 
             (a) As soon as the Registration Statement referenced in (c) below
        shall become effective, this Agreement and the Merger Agreement shall be
        submitted to the Stockholders of Farmers for approval and adoption at a
        special meeting of Stockholders to be called and held in accordance with
        law and the Articles of Incorporation and Code of Regulations of
        Farmers.
 
             (b) As promptly as possible after the date hereof, each of First
        Citizens and Farmers shall use its best efforts, separately and jointly
        with the other party, in good faith to take or cause to be taken all
        such steps as shall be necessary or advisable to obtain all consents and
        approvals of governmental authorities as are required by law or
        otherwise to effect the share exchange, including without limitation the
        approval of the Federal Reserve Board (the "Board"), the approval of the
        Ohio Department of Commerce (Division of Financial Institutions Office
        of Banks and Savings & Loans) and the approval of the Federal Deposit
        Insurance Corporation, and shall do any and all acts and things
        reasonably necessary or advisable in order to cause the share exchange
        to be consummated on the terms provided in this Agreement and the Merger
        Agreement as promptly as practicable. First Citizens and Farmers will
        cooperate in complying with and in the preparation of proxy and
        registration statements under federal and state securities laws so as to
        facilitate the exchange of shares as contemplated by this Agreement and
        the Merger Agreement.
 
             (c) Each party will assume and pay all of its fees and expenses
        incurred by it incident to the negotiation, preparation and execution of
        this Agreement, obtaining of the requisite regulatory and shareholder
        consents and approvals and all other acts incidental to, contemplated by
        or in pursuance of this Agreement. First Citizens shall be responsible
        for preparing and filing at no expense to Farmers: (i) any and all
        required regulatory applications necessary in connection with the
        transactions contemplated by this Agreement; and (ii) an S-4
        Registration Statement to be filed with the Securities and Exchange
        Commission to register the First Citizens Common Shares to be issued in
        connection with the transactions contemplated by this Agreement;
        provided, however, that such registration statement will not cover
        resales by any persons who may be considered "underwriters" under Rule
        145(c) of the Securities Act of 1933, as amended (the "1933 Act") and
        (iii) any documents to be filed or action required to be taken under any
        applicable state securities or "Blue Sky" laws in connection with the
        Merger.
 
             (d) Between the date of this Agreement and the effective time of
        the Merger, Farmers will afford to the representatives of First
        Citizens, including its counsel and auditors, during normal business
        hours, full access to any and all assets of, or information with respect
        to, Farmers to the end that First Citizens may have full opportunity to
        make an investigation, in advance of the effective time as it shall
        reasonably desire in order to effectuate the purposes of this Agreement.
        To the extent reasonable under the circumstances, the officers of
        Farmers will confer with the representatives of First Citizens and will
        furnish to First Citizens either orally or by means of such records,
        documents, and memoranda as are reasonably available or capable of
        preparation (all of which First Citizens will be permitted to make
 
                                       A-5
<PAGE>   102
 
        copies of) and such other information as First Citizens may reasonably
        request. All information furnished by one party to another party in
        connection with this Agreement and the transactions contemplated hereby
        will be kept confidential by such other party and will be used only in
        connection with this Agreement and the transactions contemplated hereby,
        except to the extent that such information: (i) is already known to such
        other party when received; (ii) thereafter becomes lawfully obtainable
        from other sources; or (iii) is required to be disclosed in any document
        filed with the Securities and Exchange Commission, the Board, or any
        other governmental agency or authority. In the event that this Agreement
        is terminated, each party will return to the other party or destroy any
        documents received by it from the other party that contain any such
        confidential information.
 
             (e) After (i) receipt of the Board's prior approval of First
        Citizens' acquisition of Farmers; (ii) the approval of the Stockholders
        of Farmers and First Citizens; and (iii) the regulatory waiting
        period(s) have expired, First Citizens shall designate the date as of
        which First Citizens desires the Merger to become effective and the time
        the Merger shall become effective shall occur at the time and on the
        date so designated. However, any date so specified unless otherwise
        agreed to by Farmers and First Citizens, shall not be later than either
        (a) the first of the month immediately following the month in which the
        last of the events described above (i-iii) occurs if said event occurs
        before the twenty-first day of such month or (b) the first day of the
        second month immediately following such month if the last of the events
        described above occurs after the twentieth day of such month.
 
             (f) Subject to the terms and conditions of this Agreement, First
        Citizens and Farmers each agree that, subject to applicable laws and to
        the fiduciary duties of its respective directors, each will promptly
        take or cause to be taken all action, and promptly do or cause to be
        done all things necessary, proper or advisable under applicable laws and
        regulations to consummate and make effective the Merger and other
        transactions contemplated by this Agreement.
 
             (g) First Citizens shall offer the existing employees of Farmers
        the opportunity to become employees of Farmers (i.e. the surviving
        corporation under the Merger Agreement) following consummation of the
        Merger; provided, however, that nothing in this section or elsewhere in
        this Agreement shall be deemed to be a contract of employment or be
        construed to give said employees any rights other than as employees at
        will under Ohio law and said employees shall not be deemed to be
        third-party beneficiaries of this provision. Farmers' employees who
        become employees of Farmers after the Merger will have their years of
        service credited toward eligibility and vesting in Pension Plan for the
        Employees of First Citizens Banc Corp. and its Affiliates and the
        Savings and Retirement Plan for First Citizens Banc Corp. and its
        Affiliates and will be entitled to participate in a variety of on-going
        educational and training programs offered by First Citizens and its
        Subsidiaries.
 
             (h) Farmers shall, prior to the time the Merger shall become
        effective, take such actions, in consultation with First Citizens, as
        shall be necessary or desirable to cause termination of any qualified
        retirement plans of Farmers at or after the effective date of Merger.
 
             (i) Two (2) member(s) of Farmers' current Board of Directors shall
        have the right to serve on the Board of Directors of First Citizens.
        Farmers hereby agrees to cause its Board of Directors to provide First
        Citizens, at least seventy-five (75) days prior to the annual meeting of
        First Citizens, with nominees, subject to First Citizens' approval, to
        serve as directors of First Citizens effective at or prior to First
        Citizens' 1998 annual shareholder meeting. Pursuant to the Merger
        Agreement, all of the current directors of Farmers shall continue as
        directors thereof after the Merger.
 
             (j) First Citizens and Farmers acknowledge that the transactions
        contemplated hereby are subject to the provisions of the Securities Act
        of 1933, as amended (the "Act") and Rule 145 thereunder. First Citizens
        agrees to prepare and file, as soon as practicable after the execution
        of this Agreement, the Registration Statement under and pursuant to the
        provisions of the Act for the purposes of registering the First Citizens
        Common Shares to be issued in connection with the transactions
        contemplated hereby. Farmers agrees to provide promptly to First
        Citizens information concerning the business and financial condition and
        affairs of Farmers as may be required or appropriate for inclusion in
        the Registration Statement and to cause its counsel and auditors to
        cooperate with First Citizens counsel
 
                                       A-6
<PAGE>   103
 
        and auditors in the preparation of such Registration Statement. First
        Citizens agrees to use its best efforts to have such Registration
        Statement declared effective under the Act as soon as may be
        practicable, and Farmers agrees to distribute the prospectus/proxy
        statement (to be prepared by and furnished at First Citizen's expense)
        contained in such Registration Statement (the Farmers "Prospectus/Proxy
        Statement") to Farmers stockholders not less than ten (10) days prior to
        the scheduled meeting of Farmers stockholders that will be held to
        consider approval of this Agreement and the Merger Agreement. Except to
        the extent permitted by Rule 145(b), First Citizens and Farmers agree
        not to publish any communication other than the Prospectus/Proxy
        Statement, in respect of this Agreement, the Merger Agreement, or the
        transactions contemplated therein. Any communication by either party
        under Rule 145(b) will be made only upon the written approval of the
        other. First Citizens and Farmers agree that, between the date the
        Registration Statement becomes effective and the effective time of the
        Merger, they will keep each other advised on a current basis of material
        developments concerning their respective businesses, including any event
        which would cause the Prospectus/proxy Statement to contain an untrue
        statement of a material fact or omit to state any material fact
        necessary to make the statements therein not misleading. First Citizens
        shall not be required to maintain the effectiveness of the Registration
        Statement for the purpose of resale of First Citizens Common Shares by
        Farmers stockholders who may be deemed to be affiliates of Farmers, as
        such term is defined in Rule 144 promulgated under the Act (the
        "Affiliates").
 
             (k) Each Affiliate of Farmers shall furnish to First Citizens a
        certificate representing that such Affiliate will not sell, assign, or
        transfer any of the First Citizens Common Shares received by such
        Affiliate as a result of the transactions contemplated by this
        Agreement, except pursuant to (a) registration under the act or (b) a
        transaction permitted by Rule 145 under the Act, or (c) a transaction in
        which, in the opinion of Squire, Sanders & Dempsey or other counsel
        satisfactory to First Citizens, or in accordance with a "no action"
        letter from the staff of the Securities and Exchange Commission, the
        First Citizens Common Shares are not required to be registered under the
        Act; and in the event of sale or other disposition pursuant to Rule 145
        such Affiliate will supply satisfactory evidence of compliance with such
        Rule to First Citizens. With respect to such representations, each
        Affiliate shall agree to hold harmless and indemnify First Citizens and
        First Citizens' officers and directors from and against any losses,
        claims, damages, expenses (including reasonable attorneys' fees), or
        liabilities to which First Citizens or any officer or director of First
        Citizens may become subject under the Act or otherwise as a result of
        the untruth, breach, or failure of such representations. Each Affiliate
        shall further agree that the certificate or certificates representing
        the First Citizens Common Shares issued to such Affiliate upon the
        consummation of the Share Exchange may bear the following restrictive
        legend:
 
               "The shares represented by this certificate have been
               issued or transferred to the registered holder as a
               result of a transaction to which Rule 145 under the
               Securities Act of 1933, as amended (the "Act"), applies.
               The shares represented by this certificate may not be
               sold, transferred or assigned, and the issuer shall not
               be required to give effect to any attempted sale,
               transfer or assignment, except pursuant to (i) current
               registration under the Act, (ii) a transaction permitted
               by Rule 145 and as to which the issuer has received
               reasonable and satisfactory evidence of compliance with
               the provisions of Rule 145, or (iii) a transaction in
               which, in the opinion of Squire, Sanders & Dempsey or
               other counsel satisfactory to the issuer or in accordance
               with a "no action" letter from the staff of the
               Securities and Exchange Commission, such shares are not
               required to be registered under the Act."
 
             First Citizens covenants and agrees to remove the foregoing
        restrictive legend from the certificate or certificates representing the
        First Citizens Common Shares issued to an Affiliate and to cancel any
        stop order instructions with respect thereto upon (i) receipt of advice
        from its counsel that such actions are appropriate under the then
        existing circumstances, or (ii) upon request of the holder thereof at
        anytime after that period ending two years following the Merger,
        provided that the holder thereof is not,
 
                                       A-7
<PAGE>   104
 
        and has not for at least the thirty day period ending prior to the
        request been an affiliate of First Citizens.
 
             (l) First Citizens shall, to the extent required by applicable
        state securities or "blue sky" laws, as promptly as practicable after
        the furnishing by Farmers of all information regarding Farmers required

        financial statements do not, as of the dates thereof, include any
        material asset or omit any material liability, absolute or contingent,

        of Regulations of First Citizens, or constitute an event which with the
        lapse of time or action by a third party, could, to the best of First
        Citizens' knowledge, result in the default under any of the foregoing or

        their respective properties or assets, at law or in equity, before any
        federal, state, municipal, local or other governmental authority,
        involving a material amount which, if resolved adversely to the interest
        of First Citizens and the Subsidiaries, would materially affect the

        best of the knowledge and belief after due inquiry of First Citizens and
        its executive officers, no one has asserted and no one has reasonable or
        valid grounds on which it reasonably can be expected that anyone will
        assert any such claims against First Citizens and the Subsidiaries based
        upon the wrongful action or inaction of First Citizens and the
        Subsidiaries or any of their respective officers, directors or
        employees.
 
             (e) At the time the Merger shall become effective and on such
        subsequent date when the former Stockholders of Farmers surrender their
        Farmers share certificates for cancellation, the First Citizens Common

             (g) The Pension Plan for the Employees of First Citizens Banc Corp.
        and its Affiliates and the Savings and Retirement Plan for First

        law to be given or made to or with any governmental agency with respect
        to the plans have been timely filed or delivered where failure to file
        will result in a penalty or result in disqualification of the plan.
        First Citizens has no knowledge either of any circumstances which would
        adversely affect the qualifications of the plans or their compliance
        with the applicable requirements of ERISA, or of any "reportable event"
        (as such term is defined in Section 4043(b) of ERISA) or any "prohibited
        transaction" (as such term is defined in Section 406 of ERISA and
        Section 4975(c) of the Internal Revenue Code) which has occurred since
        the date on which said section became applicable to the plans. With

        meaning of ERISA, such plans meet the minimum funding standards set
        forth in the Internal Revenue Code and ERISA.

        Report on Form 10-K filed with the Securities and Exchange Commission by
        First Citizens for its fiscal years ended December 31, 1996, 1995, and
        1994 including exhibits and all documents incorporated by reference
        therein, and the proxy materials disseminated by First Citizens to its
        Shareholders in connection with the 1997 Annual Meeting of Shareholders
        of First Citizens. Such Annual Report and proxy materials do not
        misstate a material fact or omit to state a material fact necessary in
        order to make the statements contained therein, in light of the
        circumstances under which they are made, not misleading.
 
             (i) Since December 31, 1996, each of First Citizens and the

        have been disposed of for fair value in the ordinary course of business
        since December 31, 1996) subject to no liens, mortgages, security
        interests, encumbrances, pledges or charges of any kind, except: (i)
        those items that secure liabilities that are reflected in said Balance
        Sheet; (ii) statutory liens for taxes not yet delinquent; and (iii)
        minor defects and irregularities in title and encumbrances which do not
        materially impair the use thereof for the purposes for which they are
        held; and such liens, mortgages, security interests, encumbrances and
        charges are not in the aggregate, material to the assets and properties
        of First Citizens. First Citizens or one of the Subsidiaries as lessee

        and to the conduct of their respective businesses, including without
        limitation, all statutes, rules and regulations pertaining to the
        conduct of banking activities except for possible technical violations

        of no material consequence to either First Citizens or the Subsidiaries.
        Neither First Citizens nor any of the Subsidiaries is the subject of,
        nor a party to, any regulatory action or agreement such as letter
        agreements, memorandum of understanding, cease and desist orders or like
        agreements. Neither First Citizens nor the Subsidiaries are in default
        under, and no event has occurred which, with the lapse of time or action
        by a third party, could, to the best of First Citizens' knowledge after
        due inquiry, result in the default under the terms of any judgment,
        decree, order, writ, rule or regulation of any governmental authority or
        court, whether federal, state or local and whether at law or in equity,
        where the default(s) could reasonably be expected to have a material
        adverse effect on the financial conditions, results of operations or
        business of First Citizens and the Subsidiaries on a consolidated basis.
 
             (l) First Citizens has duly filed all federal, state, county and

        to have been filed by First Citizens up to the date hereof. To the best

        prior to the time the Merger shall become effective, will pay all taxes,
        interest and penalties shown on such return or reports or claimed (other

        disclosed to Farmers) to be due to any federal, state, county, local or
        other taxing authority, and there is, and at the time the Merger shall
        become effective will be, no basis for any additional claim or
        assessment which might materially and adversely affect First Citizens or
        the Subsidiaries, and for which an adequate reserve has not been
        established. To the best of its knowledge and belief, First Citizens has
        paid or made adequate provision in its financial statements or its books
        and records for all taxes payable in respect of all periods ending as of
        the date thereof. To the best of its knowledge and belief First Citizens
        has, or at the time the Merger shall become effective will have, no
        material liability for any taxes, interest or penalties of any nature
        whatsoever, except for those taxes which may have arisen up to the time
        the Merger shall become effective in the ordinary course of business and
        are properly accrued on the books of First Citizens as of the time the
        Merger shall become effective.

        herewith), PCB's or urea formaldehyde, having been generated, released
        into, stored or deposited over, upon or below (in storage tanks or
        otherwise) First Citizens' premises or any other real property owned or

        the surface of the First Citizens premises or any other real property
        owned or leased by First Citizens other than other real estate owned,
        for which no investigation was conducted by First Citizens, but for
        which First Citizens has no knowledge of such from any source
        whatsoever. As used in this Agreement, the terms "hazardous substance,"
        "hazardous waste," pollutant" and "contaminant" mean any substance,
        waste, pollutant or contaminant included within such terms under any
        applicable Federal, state or local statute or regulation.
 
          8. Representations and Warranties of Farmers.  Farmers represents and

        the authorized capital stock of Farmers consists of 200,000 shares of
        common stock with $20 par value, all of which shares are issued and

        not issued in violation of the preemptive rights of any shareholder.

        will not, as of the dates thereof, include any asset in excess of $5,000
        or omit any liability in excess of $5,000, absolute or contingent, or
        other fact, the inclusion or omission of which renders such financial
        statements, in light of the circumstances under which they were made,
        misleading in any material respect. Since December 31, 1996, there has
        not been any change in the financial condition, results of operations,

        and delivery of this Agreement, the Merger Agreement nor the
        consummation of the Merger will conflict with, result in the breach of,
        constitute a default under or accelerate the performance provided by the
        terms of any law, or any rule or regulation of any governmental agency
        or authority or any judgment, order or decree of any court or other
        governmental agency to which Farmers may be subject, any contract,
        agreement or instrument to which Farmers is a party or by which Farmers
        is bound or committed, or the Articles of Incorporation or Code of
        Regulations of Farmers, or constitute an event which with the lapse of
        time or action by a third party, could, to the best of Farmer's
        knowledge, result in the default under any of the foregoing or result in
        the creation of any lien, charge, encumbrance upon any of the assets,
        property or capital stock of Farmers, except, however, in the case of
        contracts, agreements or instruments, such defaults, conflicts or
        breaches which either (i) will be cured or waived prior to the time the
        Merger becomes effective, or (ii) if not so cured or waived would not,

        law or in equity, before any federal, state, municipal, local or other
        governmental authority, involving in excess of $5,000, and to the best
        of the knowledge and belief after due inquiry of Farmers and its
        executive officers, no one has asserted and no one has reasonable or
        valid ground on which it reasonably can be expected that anyone will
        assert any such claims against Farmers based upon the wrongful action or
        inaction of Farmers or its respective officers, directors or employees.
 
             (e) Farmers has good and marketable title to all assets and
        properties, whether real or personal, tangible or intangible reflected

        value in the ordinary course of business since December 31, 1996)
        subject to no liens, mortgages, security interests, encumbrances,
        pledges or charges of any kind, except: (i) those items that secure
        liabilities that are reflected in said Balance Sheet; (ii) statutory
        liens for taxes not yet delinquent; and (iii) minor defects and

        mortgages, security interests, encumbrances and charges are not in the

        the default under the terms of any judgment, decree, order, writ, rule
        or regulation of any governmental authority or court, whether federal,
        state or local and whether at law or in equity.
 
             (g) Except as disclosed in Subsection (g) of the Disclosure Letter,

        (absolute or contingent), except for obligations reflected in this
        Agreement or the Merger Agreement, and except for obligations or
        liabilities incurred in the ordinary course of business, or mortgaged,

        any payment(s) which in the aggregate exceed $5,000 per year except for
        contracts terminable on 60 days notice. All such pension, stock bonus or
        purchase, profit-sharing, defined benefit and retirement plans set forth
        under the caption "Qualified Plans" in the Farmers Document List
        (hereinafter referred to collectively as the
 
                                      A-13
<PAGE>   110
 
        "plan") are qualified plans under Section 401(a) of the Internal Revenue
        Code and in compliance in all material respects with ERISA. All material
        notices, reports and other filings required under applicable law to be
        given or made to or with any governmental agency with respect to the
        plans have been timely filed or delivered where failure to file would
        result in a penalty and/or result in disqualification of the plan.
        Farmers has no knowledge either of any circumstances which would
        adversely affect the qualification of the plans or their compliance with
        ERISA, or of any unreported "reportable event" (as such term is defined
        in Section 4043(b) of ERISA) or, any "prohibited transaction" (as such
        term is defined in Section 406 of ERISA and Section 4975(c) of the
        Internal Revenue Code) which has occurred since the date on which said
        sections became applicable to the plans. The plans meet the minimum
        funding standards set forth in the Internal Revenue Code and ERISA.
 
             (i) Farmers has duly filed all federal, state, county and local
        income, excise, real and personal property and other tax returns and
        reports (including, but not limited to, social security, withholding,
        unemployment insurance, and sales and use taxes) required to have been
        filed by Farmers up to the date hereof. Except as set forth in
        Subsection (i) of the Disclosure Letter, to the best of the knowledge
        and belief of Farmers all such returns are true, are correct in all
        material respects, and Farmers has paid or, prior to the time the Merger
        shall become effective, will pay all taxes, interest and penalties shown
        on such return or reports or claimed together than those claims being
        contested in good faith and which have been disclosed to First Citizens
        to be due to any federal, state, county, local or other taxing
        authority, and there is, and at the time the Merger shall become
        effective will be, no basis for any additional claim or assessment in
        excess of $5,000 and for which an adequate reserve has not been
        established. To the best of its knowledge and belief, Farmers has paid,
        made or will make adequate provision in its financial statements or its
        books and records for all taxes payable in respect of all periods ending
        as of the date thereof. To the best of its knowledge and belief, Farmers
        has, or at the time the Merger shall become effective will have, no
        liability for any taxes, interest or penalties of any nature whatsoever,
        in excess of $5,000 except for those taxes which may have arisen up to
        the time the Merger shall become effective in the ordinary course of
        business and are properly accrued on the books of Farmers as of the time
        the Merger shall become effective.
 
             (j) To the best of its knowledge and belief, but without having
        undertaken an environmental audit, Farmers has no knowledge of any
        underground storage tanks, any hazardous substances, hazardous waste,
        pollutant or contaminant, including, but not limited to, asbestos
        (except as disclosed in Subsection (j) of the Disclosure Letter), PCB's
        or urea formaldehyde, having been generated, released into, stored or
        deposited over, upon or below (in storage tanks or otherwise) Farmer's
        premises or any other real property owned or leased by Farmers other
        than other real estate owned, for which no investigation was conducted
        by Farmers, but for which Farmers has no knowledge of such, or into any
        water systems on or below the surface of the Farmers premises or any
        other real property owned or leased by Farmers other than other real
        estate owned, for which no investigation was conducted by Farmers, but
        for which Farmers has no knowledge of such from any source whatsoever.
        As used in this Agreement, the terms "hazardous substance," "hazardous
        waste," pollutant" and "contaminant" mean any substance, waste,
        pollutant or contaminant included within such terms under any applicable
        Federal, state or local statute or regulation.
 
             (k) Except for its obligation to its financial advisor Austin
        Associates, Inc., as previously disclosed to First Citizens, Farmers has
        not incurred and will not incur any liability for brokerage, finders',
        agents', or investment bankers' fees or commissions in connection with
        this Agreement or the Merger Agreement or the transactions contemplated
        hereby and thereby.
 
             (l) Subject to their fiduciary duties, the directors of Farmers
        executing this Agreement shall vote the shares of Farmers held directly
        by them in favor of adoption of the Agreement.
 
             (m) All contracts and commitments (whether written or oral) that
        may have a material effect on the business of Farmers are disclosed in
        subsection (m) of the Disclosure Letter and copies of any such written
        contracts or commitments have been provided to First Citizens. All
        contracts and commitments for the lease or purchase of equipment or
        services have been entered into on an arm's length basis.

             (n) The deposits of Farmers are insured by the Federal Deposit
        Insurance Corporation in accordance with the Federal Deposit Insurance
        Act ("FDIA"). Farmers has paid all assessments and filed all reports
        required under the FDIA and is in compliance, in all material respects,
        with all regulatory requirements imposed in connection with the
        insurance of its deposits.
 
             (o) To the best of Farmer's knowledge and belief, the reserves for
        possible loan losses on the outstanding loans of Farmers (if any, as
        reflected in the balance sheet of Farmers as of December 31, 1996 (the
        "1996 Balance Sheet") are adequate to absorb all known and anticipated
        loan losses in the loan portfolio of Farmers, net of recoveries relating
        to loans previously charged off. Except as set forth in subsection (o)
        of the Disclosure Letter, there are no loans of Farmers the present
        principal balance of which is in excess of $5,000 that have been
        classified orally or in writing by bank examiners (regulatory or
        internal) as "Other Loans Specifically Mentioned," "Substandard,"
        "Doubtful," or "Loss," as of the last examination date (which shall
        include the date on which any examination prior to the effective time is
        concluded). To the best of Farmer's knowledge and belief, each loan in
        the principal amount of $5,000 or greater reflected as an asset of
        Farmers in the 1996 Balance Sheet or acquired by Farmers since December
        31, 1996, is the legal, valid and binding obligation of the obligor and
        any guarantor named therein, and no such loan is subject to any defense,
        offset or counterclaim. Except for pledges to secure public and trust
        deposits, to the best of Farmer's knowledge and belief, none of the
        investments reflected in the 1996 Balance Sheet under the heading
        "Investment Securities," and none of the investments made by Farmers
        since December 31, 1996, is subject to any restriction, whether
        contractual or statutory, which impairs the ability of Farmers freely to
        dispose of such investment at any time. Farmers is not a party to any
        repurchase agreements. Except as set forth in subsection (o) of the
        Disclosure Letter, and except for transactions aggregating less than
        $5,000, Farmers has not sold or otherwise disposed of any assets in a
        transaction in which the acquirer of such assets or any other person has
        the right, either conditionally or absolutely, to require Farmers to
        repurchase or otherwise re acquire any such assets.
 
             (p) Prior to the Closing, Farmers will have provided First Citizens
        with a list of all certificates of deposit or checking, savings or other
        deposits and a list of all certificates of deposit or checking, savings
        or other deposits owned by directors and officers of Farmers and their
        affiliates as of the last day of the calendar month immediately prior to
        the Closing. In addition, Farmers shall provide First Citizens with a
        list of (i) all certificates of deposit, checking, savings or other
        deposits in excess of $100,000 and (ii) all customers with aggregate
        deposits in excess of $100,000.
 
             (q) Subsection (q) of the Disclosure Letter contains a list and a
        brief description of all insurance policies currently in force with
        respect to Farmers. All premiums due on such policies have been paid,
        and such policies will continue to remain in force through the Effective
        Time. Subsection (q) the disclosure letter also contains a description
        of all claims in excess of $1,000 currently pending under such insurance
        policies, together with a list of all other claims in excess of $1,000
        which have been filed during the last three (3) years and a description
        of the disposition thereof.
 
             (r) Except to the extent reflected or reserved against in the 1996
        Balance Sheet or in the notes thereto, as of the date of such Balance
        Sheet, Farmers has no liabilities or obligations, secured or unsecured,
        whether accrued, absolute, contingent or otherwise, which would
        materially and adversely affect the financial condition, results of
        operations, assets, or business of Farmers.
 
             (s) Except for loans made in the ordinary course of business,
        Farmers has no business relationships, business transactions or
        indebtedness with or to any of its officers and directors.
 
          9. Action by Farmers Pending Effective Time.  Farmers agrees that from
     the date of this Agreement until the time the Merger shall become
     effective, except with prior written permission of First Citizens:
 
             (a) Beginning with the date hereof and until such time as the
        Merger shall become effective, Farmers will not declare or pay any
        dividends or make any distributions other than regular cash dividends,
        payable at such times and in amounts consistent with past practice and
        not to exceed the per share rate paid in the prior calendar year,
        provided that if the merger shall occur prior to the payment of
 
                                      A-15
<PAGE>   112
 
        the regular annual cash dividend of Farmers, Farmers may pay a cash
        dividend in an amount equal to the per share rate paid in the prior
        calendar year, prorated to the date of the Merger. If, prior to the
        consummation of the Merger, Farmers shall declare a stock dividend or
        make distributions upon or subdivide, split up, reclassify or combine
        its shares of common stock in any security convertible into its common
        stock, appropriate adjustment or adjustments will be made in the
        foregoing per share dividend rate.
 
             (b) Farmers will not issue, sell, grant any option for, or acquire
        for value any shares of its capital stock or otherwise effect any change
        in connection with its capitalization.
 
             (c) Except as otherwise set forth in or contemplated by this
        Agreement or the Merger Agreement, Farmers will carry on its businesses
        in substantially the same manner as heretofore, keep in full force and
        effect insurance comparable in amount and scope of coverage to that now
        maintained by it and use its best efforts to maintain and preserve its
        business organization intact.
 
             (d) Farmers will not: (i) enter into any transaction other than in
        the ordinary course of business or incur or agree to incur any
        obligation or liability except liabilities incurred and obligations
        entered into in the ordinary course of business; (ii) change its
        lending, investment, liability management and other policies in any
        respect; (iii) except as committed for adjustment as of the date hereof
        and consistent with prior practice, grant any general or uniform
        increase in the rates of pay of employees; (iv) incur or commit to any
        capital expenditures other than in the ordinary course of business, or
        (v) merge into, consolidate with or sell its assets to any other
        corporation or person, or permit any other corporation to be merged or
        consolidated with it or acquire all of the assets of any other
        corporation or person.
 
             (e) Farmers will not change its method of accounting in effect at
        December 31, 1996 except as required by changes in generally accepted
        accounting principles and concurred in by Farmer's independent auditors,
        or change any of its methods of reporting income and deductions for
        Federal income tax purposes from those employed in the preparation of
        Farmer's Federal income tax returns for the taxable year ending December
        31, 1996, except for changes required by law.
 
             (f) Farmers will promptly advise First Citizens in writing of all
        material actions taken by the directors and Stockholders of Farmers,
        furnish First Citizens with copies of all minutes of such action and
        monthly interim financial statements of Farmers as they become
        available, commencing with the April 1997 statements, and keep First
        Citizens fully informed concerning all developments which in the opinion
        of Farmers may have a material effect upon the business, properties or
        condition (either financial or otherwise) of Farmers.
 
          10. Action by First Citizens Pending Effective Time.  First Citizens
     agrees that from the date of this Agreement until the time the Merger shall
     become effective:
 
             (a) First Citizens will carry on its business in substantially the
        same manner as heretofore except as otherwise set forth in or
        contemplated by this Agreement, and First Citizens will keep in full

        preserve its business organization intact.
 
             (b) First Citizens will not change its methods of accounting in
        effect at December 31, 1996, except as required by changes in generally
        accepted accounting principles as concurred in by First Citizens'
        independent auditors, or change any of its methods of reporting income
        and deductions for Federal income tax purposes from those employed in
        the preparation of the Federal income tax returns of First Citizens'
        Subsidiaries for the taxable year ended December 31, 1996, except for
        changes required by law or take any action which could jeopardize the
        tax free nature of the Merger or the pooling of interests accounting
        treatment for the Merger.
 
             (c) First Citizens will furnish Farmers with copies of interim
        financial statements of First Citizens and all reports, schedules and
        statements filed by or delivered for First Citizens pursuant to the
        Securities and Exchange Act of 1934 and the rules and regulations
        promulgated thereunder, as they become available, and keep Farmers fully
        informed concerning all developments which in the opinion
 
                                      A-16
<PAGE>   113
 
        of First Citizens may have a material effect upon the business,
        properties or condition (either financial or otherwise) of First
        Citizens.
 
          11. Conditions to Obligations of First Citizens.  The obligations of
     First Citizens under this Agreement and the Merger Agreement are subject,
     unless waived by First Citizens, to the satisfaction of the following
     conditions on or prior to the time the Merger shall become effective:
 
             (a) There shall not have been any material adverse change or
        discovery of a condition or the occurrence of an event which has or is
        likely to result in such a change, in the financial condition, aggregate

        contemplated by this Agreement or the Merger Agreement and except also
        for representations as of a specified time other than the time the
        Merger shall become effective, which shall be true in all material

        so found to have breached this Agreement shall indemnify the other
        parties for their respective costs, fees and expenses of its counsel,

     proxies from such Stockholders.

        Stock, be paid cash, without interest, by First Citizens for such
        fractional share(s). The cash paid for fractional shares shall be based
        upon $33.50 per share of First Citizens Common Shares.
 
             (c) As soon as practicable after the time the Merger shall become
        effective, and subject to the provisions set forth above relating to the
        fractional shares, the corporate trust department of Fifth Third Bank,
        First Citizens' exchange agent, will distribute to the former holders of
        Farmers Common Stock in exchange for and upon surrender for cancellation
        by such holders of a certificate or certificates formerly representing
        shares of Farmers Common Stock the certificate(s) for First Citizens
        Common Shares in accordance with the provisions regarding the exchange
        of shares of Farmers Common Stock set forth in paragraph 1(a)(i) of this
        Merger Agreement. Each certificate formerly representing Farmers Common
        Stock (other than certificates representing shares of Farmers Common
        Stock subject to the rights of dissenting shareholders) shall be deemed
        for all purposes to evidence the ownership of the number of whole First
        Citizens Common Shares and cash for fractional share interests in First
        Citizens Common Shares into which such shares have been converted.
        Certificates representing shares of Farmers Common Stock held by a
        stockholder of Farmers, shall be aggregated together in determining the
        number of fractional shares for which such shareholder shall receive
        cash as provided for herein. Until surrender of the certificate or
        certificates formerly representing shares of Farmers Common Stock, the
        holder thereof shall not be entitled to receive any dividend or other
        payment or distribution payable to holders of First Citizens Common
        Shares. Upon such surrender (or in lieu of surrender other provisions
        reasonably satisfactory to First Citizens as are made as set forth in
        the next following paragraph), there shall be paid to the person
        entitled thereto the aggregate amount of dividends or other payments or
        distributions (in each case without interest) which became payable after
        the time the Merger shall become effective on the whole First Citizens
        Common Shares represented by the certificates issued upon such surrender
        and exchange or in accordance with such other provisions, as the case
        may be. After the time the Merger shall become effective, the holders of
        certificates formerly representing shares of Farmers Common Stock shall
        cease to have rights with respect to such shares except such rights, if
        any, as a holder of certificates formerly representing shares of Farmers
        Common Stock may have as dissenting shareholders pursuant to Ohio law
        and except as aforesaid, their sole rights shall be to exchange said
        certificates for certificates for First Citizens Common Shares in
        accordance with this Merger Agreement.

        Certificates formerly representing shares of Farmers Common Stock
        surrendered for cancellation by each shareholder entitled to exchange
        shares of Farmers Common Stock for First Citizens Common Shares by
        reason of the Merger shall be accompanied by such appropriate
        instruments of transfer as First Citizens may reasonably require,
        provided, however, that if there be delivered to First Citizens by any
        person who is unable to produce any such certificate formerly
        representing shares of Farmers Common Stock for transfer (i) evidence to
        the reasonable satisfaction of First Citizens that any such certificate
        has been lost, wrongfully taken or destroyed, and (ii) such indemnity
        agreement as reasonably may be requested by First Citizens to save it
        harmless, and (iii) evidence to the reasonable satisfaction of First
        Citizens that such person is the owner of the shares theretofore
        represented by each certificate claimed by him to be lost, wrongfully
        taken or destroyed and that he is the person who would be entitled to
        present each such certificate and to receive First Citizens Common
        Shares pursuant to this Merger Agreement, then First Citizens (or an
        Exchange Agent, as the case may be), in the absence of actual notice to
        it that any shares theretofore represented by any such certificate have
        been acquired by a bona fide purchaser, shall deliver to such person the
        certificate(s) representing First Citizens Common Shares which such
        person would have been entitled to receive upon surrender of each such
        lost, wrongfully taken or destroyed certificate representing shares of
        Farmers Common Stock.
 
     2. After the Effective Time, there shall be no transfers of the stock
transfer books of New Bank of any certificates representing shares of New Bank
Common Stock. After the Effective Time, upon presentation to the Surviving
Corporation of certificates formerly representing capital stock of New Bank,
such certificates shall be canceled.
 
     3. The Resulting Corporation shall have a capital structure equal to the
following:
 
          (a) Common stock of $4,000,000.00, consisting of 200,000 shares of $20
     par value all of which will be issued and outstanding immediately following
     the Effective Time of the Merger; and
 
          (b) Surplus of $4,000,000.00; and
 
          (c) Undivided profits, including capital reserves, of $5,877,000,
     adjusted for all earnings and losses between January, 1997, and the
     Effective Time of the Merger.

                                EFFECT OF MERGER
 
     From and after the Effective Time, the Surviving Corporation shall have all
of the rights, interests, privileges, powers, immunities and franchises (public
and private) of each of the constituent corporations, and all property (real,
personal and mixed), all debts due on whatever account, and all other chooses in
action, of each of the constituent corporations. All interests of or belonging
to or due to either of the constituent corporations shall thereupon be deemed to
be transferred to and vested in the Surviving Corporation without act or deed
and no title to any real estate or any interest therein vested in either of the
constituent corporations shall revert or be in any way impaired because of the
Merger.
 
                                   ARTICLE VI
 
                             SURVIVING CORPORATION
 
     From and after the Effective Time, the Surviving Corporation shall be
responsible for all obligations of each of the constituent corporations and each
claim existing and each action or proceeding pending by or against either of the
constituent corporations may be prosecuted as if the Merger had not taken place,
and the Surviving Corporation may be substituted in the place of such
constituent corporation. No right of any creditor of either constituent
corporation and no lien upon the property of either constituent corporation
shall be impaired by the Merger.

                               FURTHER DOCUMENTS
 
     If at any time the Surviving Corporation shall consider or be advised that
any further assignments, conveyances or assurances in law are necessary or
desirable to vest, perfect or confirm of record in the Surviving Corporation the
title to any property or rights of the constituent corporations, or otherwise to
carry out the provisions hereof, the persons who were the proper officers and
directors of the constituent corporations immediately prior to the Effective
Time (or their successors in office) shall execute and deliver any and all
proper deeds, assignments and assurances in law, and do all things necessary or
proper, to vest, perfect or confirm title to such property or rights in the
Surviving Corporation, including, but not limited to, filing with each court or
other public tribunal, agency or officer by which Farmers or New Bank have been
appointed in the capacity of fiduciary or agent, and in the court file of each
estate, suit or proceeding in which any of them has been acting, a statement
setting forth the information required by law or otherwise to carry out the
provisions hereof.

                                  TERMINATION
 
     Notwithstanding the adoption and approval of this Agreement and the Merger
by the shareholders of Farmers and New Bank, this Agreement and the Merger may
be terminated:
 
          (a) At any time prior to the Effective Time, by the mutual consent of
     the Boards of Directors of Farmers and New Bank; or
 
          (b) This Merger Agreement shall automatically terminate in the event
     of the termination of the Agreement and Plan of Reorganization dated July
     3, 1997, as amended as of the date hereof, by and between Farmers and First
     Citizens to which it relates.
 
          (c) At any time prior to the Effective Time, by Farmers or New Bank if
     there shall have been a final judicial determination (as to which all
     periods for appeal shall have expired and no appeal shall be pending) that
     any material provision of this Agreement or of the Merger is illegal,
     invalid or unenforceable;
 
          (d) By Farmers if the average closing sale price of First Citizens
     Common Shares for the ten consecutive trading days ending on the third
     trading day prior to the Effective Time is $26.80 or less. As used in this
     Agreement, "trading days" shall mean days on which actual trades of First
     Citizens Common Shares occur as reported by SNL Securities of
     Charlottesville, Virginia.
 
     In the event that this Agreement is terminated pursuant to this Article
VIII, the Merger provided for herein shall be abandoned automatically and
without any further act or deed by the parties hereto.
 
                                   ARTICLE IX
 
                    CONDITIONS TO CONSUMMATION OF THE MERGER

obligations of the parties hereto is subject to the satisfaction of the
provisions and conditions of the Agreement and Plan of Reorganization by and
between Farmers and First Citizens dated July 3, 1997, as amended as of the date
hereof.

                                   APPENDIX C
 
            DISSENTERS' RIGHTS UNDER SECTIONS 1115.19 AND 1701.85 OF
                             THE OHIO REVISED CODE
 
1115.19 DISSENTING SHAREHOLDERS
 
     Unless the articles of incorporation of the state bank otherwise provide,
any shareholder of a state bank that has been consolidated or merged with, or
whose assets have been transferred to, another state bank or a national bank,
savings bank or savings association pursuant to any provision of this chapter
other than section 1115.15 of the Revised Code, who did not vote in favor of the
consolidation, merger, or transfer, shall be paid the fair cash value, as of the
day before the vote was taken authorizing any such action, of the shares held,
excluding from any such fair cash value any appreciation or depreciation in
consequence of the consolidation, merger, or transfer which entitled the
shareholder to this relief. Section 1701.85 of the Revised Code shall govern
with respect to the shareholder's rights and any limitations on those rights.
Any shareholder who does not object and demand in writing the payment of the
fair cash value of the shares in the manner and at the time provided in section
1701.85 of the Revised Code, shall be bound by the vote of the board of
directors or the assenting shareholders of the state bank.
 
1701.85 QUALIFICATIONS OF AND PROCEDURES FOR DISSENTING SHAREHOLDERS
 
     (A)(l) A shareholder of a domestic corporation is entitled to relief as a
dissenting shareholder in respect of the proposals described in sections
1701.74, 1701.76, and 1701.84 of the Revised Code, only in compliance with this
section.
 
     (2) If the proposal must be submitted to the shareholders of the
corporation involved, the dissenting shareholder shall be a record holder of the
shares of the corporation as to which he seeks relief as of the date fixed for
the determination of shareholders entitled to notice of a meeting of the
shareholders at which the proposal is to be submitted, and such shares shall not
have been voted in favor of the proposal. Not later than ten days after the date
on which the vote on the proposal was taken at the meeting of the shareholders,
the dissenting shareholder shall deliver to the corporation a written demand for
payment to him of the fair cash value of the shares as to which he seeks relief,
which demand shall state his address, the number and class of such shares, and
the amount claimed by him as the fair cash value of the shares.
 
     (3) The dissenting shareholder entitled to relief under division (C) of
section 1701.84 of the Revised Code in the case of a merger pursuant to section
1701.80 of the Revised Code and a dissenting shareholder entitled to relief
under division (E) of section 1701.84 of the Revised Code in the case of a
merger pursuant to section 1701.801 of the Revised Code shall be a record holder
of the shares of the corporation as to which he seeks relief as of the date on
which the agreement of merger was adopted by the directors of that corporation.
Within twenty days after he has been sent the notice provided in section 1701.80
or 1701.801 of the Revised Code, the dissenting shareholder shall deliver to the
corporation a written demand for payment with the same information as that
provided for in division (A)(2) of this section.
 
     (4) In the case of a merger or consolidation, a demand served on the
constituent corporation involved constitutes service on the surviving or the new
entity, whether the demand is served before, on, or after the effective date of
the merger or consolidation.
 
     (5) If the corporation sends to the dissenting shareholder, at the address
specified in his demand, a request for the certificates representing the shares
as to which he seeks relief, the dissenting shareholder, within fifteen days
from the date of the sending of such request, shall deliver to the corporation
the certificates requested so that the corporation may forthwith endorse on them
a legend to the effect that demand for the fair cash value of such shares has
been made. The corporation promptly shall return such endorsed certificates to
the dissenting shareholder. A dissenting shareholder's failure to deliver such
certificates terminates his rights as a dissenting shareholder, at the option of
the corporation, exercised by written notice sent to the dissenting shareholder
within twenty days after the lapse of the fifteen-day period, unless a court for
good cause shown otherwise directs. If shares represented by a certificate on
which such a legend has been endorsed are transferred, each new certificate
 
                                       C-1
<PAGE>   125
 
issued for them shall bear a similar legend, together with the name of the
original dissenting holder of such shares. Upon receiving a demand for payment
from a dissenting shareholder who is the record holder of uncertificated
securities, the corporation shall make an appropriate notation of the demand for
payment in its shareholder records. If uncertificated shares for which payment
has been demanded are to be transferred, any new certificate issued for the
shares shall bear the legend required for certificated securities as provided in
this paragraph. A transferee of the shares so endorsed, or of uncertificated
securities where such notation has been made, acquires only such rights in the
corporation as the original dissenting holder of such shares had immediately
after the service of a demand for payment of the fair cash value of the shares.
A request under this paragraph by the corporation is not an admission by the
corporation that the shareholder is entitled to relief under this section.
 
     (B) Unless the corporation and the dissenting shareholder have come to an
agreement on the fair cash value per share of the shares as to which the
dissenting shareholder seeks relief, the dissenting shareholder or the
corporation, which in case of a merger or consolidation may be the surviving or
new entity, within three months after the service of the demand by the
dissenting shareholder, may file a complaint in the court of common pleas of the
county in which the principal office of the corporation that issued the shares
is located or was located when the proposal was adopted by the shareholders of
the corporation, or, if the proposal was not required to be submitted to the
shareholders, was approved by the directors. Other dissenting shareholders,
within that three-month period, may join as plaintiffs or may be joined as
defendants in any such proceeding, and any two or more such proceedings may be
consolidated. The complaint shall contain a brief statement of the facts,
including the vote and the facts entitling the dissenting shareholder to the
relief demanded. No answer to such a complaint is required. Upon the filing of
such a complaint, the court, on motion of the petitioner, shall enter an order
fixing a date for a hearing on the complaint and requiring that a copy of the
complaint and a notice of the filing and of the date for hearing be given to the
respondent or defendant in the manner in which summons is required to be served
or substituted service is required to be made in other cases. On the day fixed
for the hearing on the complaint or any adjournment of it, the court shall
determine from the complaint and from such evidence as is submitted by either
party whether the dissenting shareholder is entitled to be paid the fair cash
value of any shares and, if so, the number and class of such shares. If the
court finds that the dissenting shareholder is so entitled, the court may
appoint one or more persons as appraisers to receive evidence and to recommend a
decision on the amount of the fair cash value. The appraisers have such power
and authority as is specified in the order of their appointment. The court
thereupon shall make a finding as to the fair cash value of a share and shall
render judgment against the corporation for the payment of it, with interest at
such rate and from such date as the court considers equitable. The costs of the
proceeding, including reasonable compensation to the appraisers to be fixed by
the court, shall be assessed or apportioned as the court considers equitable.
The proceeding is a special proceeding and final orders in it may be vacated,
modified, or reversed on appeal pursuant to the Rules of Appellate Procedure
and, to the extent not in conflict with those rules, Chapter 2505. of the
Revised Code. If, during the pendency of any proceeding instituted under this
section, a suit or proceeding is or has been instituted to enjoin or otherwise
to prevent the carrying out of the action as to which the shareholder has
dissented, the proceeding instituted under this section shall be stayed until
the final determination of the other suit or proceeding. Unless any provision in
division (D) of this section is applicable, the fair cash value of the shares
that is agreed upon by the parties or fixed under this section shall be paid
within thirty days after the date of final determination of such value under
this division, the effective date of the amendment to the articles, or the
consummation of the other action involved, whichever occurs last. Upon the
occurrence of the last such event, payment shall be made immediately to a holder
of uncertificated securities entitled to such payment. In the case of holders of
shares represented by certificates, payment shall be made only upon and
simultaneously with the surrender to the corporation of the certificates
representing the shares for which the payment is made.
 
     (C) If the proposal was required to be submitted to the shareholders of the
corporation, fair cash value as to those shareholders shall be determined as of
the day prior to the day on which the vote by the shareholders was taken and, in
the case of a merger pursuant to section 1701.80 or 1701.801 of the Revised
Code, fair cash value as to shareholders of a constituent subsidiary corporation
shall be determined as of the day before the adoption of the agreement of merger
by the directors of the particular subsidiary corporation. The fair cash value
of a share for the purposes of this section is the amount that a willing seller
who is under no compulsion to sell would be willing to accept and that a willing
buyer who is under no compulsion to purchase would be willing to pay, but in
 
                                       C-2
<PAGE>   126
 
no event shall the fair cash value of a share exceed the amount specified in the
demand of the particular shareholder. In computing such fair cash value, any
appreciation or depreciation in market value resulting from the proposal
submitted to the directors or to the shareholders shall be excluded.
 
     (D)(1) The right and obligation of a dissenting shareholder to receive such
fair cash value and to sell such shares as to which he seeks relief, and the
right and obligation of the corporation to purchase such shares and to pay the
fair cash value of them terminates if any of the following applies:
 
          (a) The dissenting shareholder has not complied with this section,
     unless the corporation by its directors waives such failure;
 
          (b) The corporation abandons the action involved or is finally
     enjoined or prevented from carrying it out, or the shareholders rescind
     their adoption of the action involved;
 
          (c) The dissenting shareholder withdraws his demand, with the consent
     of the corporation by its directors;
 
          (d) The corporation and the dissenting shareholder have not come to an
     agreement as to the fair cash value per share, and neither the shareholder
     nor the corporation has filed or joined in a complaint under division (B)
     of this section within the period provided in that division.
 
     (2) For purposes of division (D)(1) of this section, if the merger or
consolidation has become effective and the surviving or new entity is not a
corporation, action required to be taken by the directors of the corporation
shall be taken by the general partners of a surviving or new partnership or the
comparable representatives of any other surviving or new entity.
 
     (E) From the time of the dissenting shareholder's giving of the demand
until either the termination of the rights and obligations arising from it or
the purchase of the shares by the corporation, all other rights accruing from
such shares, including voting and dividend or distribution rights, are
suspended. If during the suspension, any dividend or distribution is paid in
money upon shares of such class or any dividend, distribution, or interest is
paid in money upon any securities issued in extinguishment of or in substitution
for such shares, an amount equal to the dividend, distribution, or interest
which, except for the suspension, would have been payable upon such shares or
securities, shall be paid to the holder of record as a credit upon the fair cash
value of the shares. If the right to receive fair cash value is terminated other
than by the purchase of the shares by the corporation, all rights of the holder
shall be restored and all distributions which, except for the suspension, would
have been made shall be made to the holder of record of the shares at the time
of termination.

                     FAIRNESS OPINION OF MCDONALD & COMPANY
<PAGE>   128
 
                                            , 1997
 
Board of Directors
First Citizens Banc Corp.
100 East Water Street
Sandusky, OH 44871
 
Gentlemen and Madam:
 
     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,
no par value ("First Citizens Common Stock"), of First Citizens Banc Corp.
("First Citizens") of the exchange ratio as set forth in Article IV, Section 1
of the Merger Agreement, which is Appendix A to the Agreement and Plan of
Reorganization dated July 3, 1997, as amended November 25, 1997 and November 26,
1997, (collectively, the "Agreements"), by and among First Citizens, Farmers
Interim Bank ("Interim Bank"), and The Farmers State Bank of New Washington,
Ohio ("Farmers").
 
     The Agreements provide for the merger (the "Merger") of Farmers with and
into Interim Bank, a newly formed wholly owned subsidiary of First Citizens,
pursuant to which, among other things, at the Effective Time (as defined in the
Agreements), outstanding shares of Farmers common stock, par value $20.00 per
share ("Farmers Common Stock"), will be exchanged for 6.06 shares of First
Citizens Common Stock as set forth in Article IV, Section 1 of the Agreements
(the "Exchange Ratio"). The terms and conditions of the Merger are more fully
set forth in the Agreements.
 
     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 First Citizens' financial advisor in connection with, and
have participated in certain negotiations leading to, the execution of the
Agreements. In connection with rendering our opinion set forth herein, we have
among other things:
 
     (i) Reviewed First Citizens' Annual Reports to Shareholders and Annual
Reports on Form 10-K for each of the years ended December 31, 1996, December 31,
1995 and December 31, 1994, including the audited financial statements contained
therein; and First Citizens' Quarterly Reports on Form 10-Q for the three month
periods ended September 30, 1997; June 30, 1997 and March 31, 1997.
 
     (ii) Reviewed Farmers' Consolidated Report of Income and Consolidated
Report of Condition for Insured Commercial and State-Chartered Savings Banks for
the fiscal years ended December 31, 1996, December 31, 1995 and December 31,
1994; and Farmers' Consolidated Report of Income and Consolidated Report of
Condition for Insured Commercial and State-Chartered Savings Banks, as amended,
for the three month period ended September 30, 1997, June 30, 1997 March 31,
1997.
 
     (iii) Reviewed certain other public and nonpublic information, primarily
financial in nature, relating to the respective businesses, earnings, assets and

     (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 Agreements and their schedules and exhibits and certain
related documents; and
 
     (ix) Performed such other reviews and 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, warranties and covenants of First Citizens and Farmers
contained in the Agreements. We have not been engaged to undertake, and have not
assumed any responsibility for, nor have we 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 First Citizens or Farmers, 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 First
Citizens or Farmers. 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 First Citizens and Farmers as to the future performance of First
Citizens, Farmers, and First Citizens and Farmers combined, as the case may be.
We have not been engaged to and we have not assumed any responsibility for, nor
have we conducted any independent investigation or verification of such matters,
and 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 Agreements, including the
tax-free treatment of the merger to the holders of Farmers Common Stock, would
be satisfied and that the Merger would be consummated on a timely basis in the
manner contemplated by the Agreements.
 
     We will receive a fee for our services as financial advisor to First
Citizens, a substantial portion of which is contingent upon closing of the
Merger. We will also receive a fee for our services in rendering this opinion.
 
     In the ordinary course of business, we may trade securities of First
Citizens and Farmers 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. In addition, McDonald & Company has provided investment banking
services to First Citizens in the past (including financial advisory services
with respect to prior acquisition transactions) and may provide such services in
the future.
 
     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 First Citizens Common Stock, and does not address the underlying
business decision by First Citizens' Board of Directors to effect the Merger,
does not compare or discuss the relative merits of any competing proposal or any
other terms of the Merger, and does not constitute a recommendation to any First
Citizens 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
First Citizens Common Stock or Farmers Common Stock may be at the effective date
of the Merger or as to the prospects of First Citizens' business or Farmers'
business.
 
     This opinion is directed to and has been prepared solely for the
confidential use of the Board of Directors of First Citizens. We do not believe
that we are acting as agents of the First Citizens Board of Directors nor the
holders of the First Citizens Common Stock, and we do not believe that any
person other than the First Citizens Board of Directors has any legal right
under state law to rely on this opinion. This opinion shall 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 First Citizens
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 is fair to the holders of First Citizens Common
Stock from a financial point of view.
 
                                        Very truly yours,

Board of Directors
The Farmers State Bank of New Washington
102 South Kibler Street
New Washington, OH 44854-9401
 
Members of the Board:
 
     You have requested our opinion as to the fairness, from a financial point
of view, to The Farmers State Bank of New Washington ("Farmers") and its
shareholders of the terms of the Agreement and Plan of Reorganization dated as
of July 3, 1997, as amended November 25, 1997 and November 26, 1997, and the
related Merger Agreement dated as of November 26, 1997 (together, the
"Agreement") between Farmers and First Citizens Banc Corp, Sandusky, Ohio
("First Citizens"). The terms of the Agreement provide for the acquisition of
Farmers by First Citizens (the "Merger"). The Merger will be completed through a
merger of Farmers with Farmers Interim Bank, a wholly owned subsidiary of First
Citizens, formed for the limited purpose of effecting the Merger. As a result of
the Merger, Farmers will become a wholly-owned subsidiary of First Citizens.
 
     The terms of the Agreement provide for each outstanding share of Farmers
common stock to be converted into the right to receive 6.06 shares of First
Citizens common stock. Based on 200,000 shares of Farmers stock issued and
outstanding, a total of 1,212,000 shares of First Citizens stock shall be issued
in the Merger.
 
     In carrying out our engagement, we have reviewed and analyzed material
bearing upon the financial and operating condition of Farmers and First
Citizens, including but not limited to the following: (i) the Proxy
Statement/Prospectus; (ii) the financial statements of Farmers and First
Citizens for the period 1992 through September, 1997; (iii) certain other
publicly available information regarding Farmers and First Citizens; (iv)
publicly available information regarding the performance of certain other
companies whose business activities were believed by Austin Associates to be
generally comparable to those of Farmers and First Citizens; (v) the financial
terms, to the extent publicly available, of certain comparable transactions; and
(vi) such other analysis and information as we deemed relevant.
 
     In our review and analysis, we relied upon and assumed the accuracy and
completeness of the financial and other information provided to us or publicly
available, and have not attempted to verify the same. We have made no
independent verification as to the status of individual loans made by Farmers or
First Citizens, and have instead relied upon representations and information
concerning loans of Farmers and First Citizens in the aggregate. In rendering
our opinion, we have assumed that the transaction will be a tax-free
reorganization with no material adverse tax consequences to Farmers or First
Citizens, or to Farmers shareholders receiving First Citizens stock. In
addition, we have assumed in the course of obtaining the necessary regulatory
approvals for the transaction, no condition will be imposed that will have a
material adverse effect on the contemplated benefits of the transaction to
Farmers and its shareholders.
 
     Based upon our analysis and subject to the qualifications described herein,
we believe that as of the date of this letter, the terms of the Agreement are
fair, from a financial point of view, to Farmers and its shareholders.
 
     For our services in rendering this opinion, Farmers will pay us a fee and
indemnify us against certain liabilities.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
     Section 1701.13(E) of the Ohio Revised Code grants corporations broad
powers to indemnify directors, officers, employees and agents. Section
1701.13(E) provides:
 
          (E)(1) A corporation may indemnify or agree to indemnify any person
     who was or is a party or is threatened to be made a party, to any
     threatened, pending, or completed action, suit, or proceeding, whether
     civil, criminal, administrative, or investigative, other than an action by
     or in the right of the corporation, by reason of the fact that he is or was
     a director, officer, employee, or agent of the corporation, or is or was
     serving at the request of the corporation as a director, trustee, officer,
     employee, member, manager, or agent of another corporation, domestic or
     foreign, nonprofit or for profit, a limited liability company, or a
     partnership, joint venture, trust, or other enterprise, against expenses,
     including attorney's fees, judgments, fines, and amounts paid in settlement
     actually and reasonably incurred by him in connection with such action,
     suit, or proceeding, if he acted in good faith and in a manner he
     reasonably believed to be in or not opposed to the best interests of the
     corporation, and with respect to any criminal action or proceeding, if he
     had no reasonable cause to believe his conduct was unlawful. The
     termination of any action, suit, or proceeding by judgment, order,
     settlement, or conviction, or upon a plea of nolo contendere or its
     equivalent, shall not, of itself, create a presumption that the person did
     not act in good faith and in a manner he reasonably believed to be in or
     not opposed to the best interests of the corporation, and, with respect to
     any criminal action or proceeding, he had reasonable cause to believe that
     his conduct was unlawful.
 
          (2)   A corporation may indemnify or agree to indemnify any person who
     was or is a party, or is threatened to be made a party, to any threatened,
     pending, or completed action or suit by or in the right of the corporation
     to procure a judgment in its favor, by reason of the fact that he is or was
     a director, officer, employee, member, manager, or agent of the
     corporation, or is or was serving at the request of the corporation as a
     director, trustee, officer, employee, member, manager, or agent of another
     corporation, domestic or foreign, nonprofit or for profit, a limited
     liability company, or a partnership, joint venture, trust, or other
     enterprise, against expenses, including attorney's fees, actually and
     reasonably incurred by him in connection with the defense or settlement of
     such action or suit, if he acted in good faith and in a manner he
     reasonably believed to be in or not opposed to the best interests of the
     corporation, except that no indemnification shall be made in respect of any
     of the following:
 
          (a) Any claim, issue, or matter as to which such person is adjudged to
     be liable for negligence or misconduct in the performance of his duty to
     the corporation unless, and only to the extent that, the court of common
     pleas or the court in which such action or suit was brought determines,
     upon application, that, despite the adjudication of liability, but in view
     of all the circumstances of the case, such person is fairly and reasonably
     entitled to indemnity for such expenses as the court of common pleas or
     such other court shall deem proper;
 
          (b) Any action or suit in which the only liability asserted against a
     director is pursuant to section 1701.95 of the Revised Code.
 
          (3)   To the extent that a director, trustee, officer, employee,
     member, manager, or agent has been successful on the merits or otherwise in
     defense of any action, suit, or proceeding referred to in division (E)(1)
     or (2) of this section, or in defense of any claim, issue, or matter
     therein, he shall be indemnified against expenses, including attorney's
     fees, actually and reasonably incurred by him in connection with the
     action, suit, or proceeding.
 
          (4)   Any indemnification under division (E)(1) or (2) of this
     section, unless ordered by a court, shall be made by the corporation only
     as authorized in the specific case, upon a determination that
     indemnification of the director, trustee, officer, employee, member,
     manager, or agent is proper in the circumstances because he has met the
     applicable standard of conduct set forth in division (E)(1) or (2) of this
     section. Such determination shall be made as follows:
 
                                      II-1
<PAGE>   134
 
          (a) By a majority vote of a quorum consisting of directors of the
     indemnifying corporation who were not and are not parties to or threatened
     with the action, suit, or proceeding referred to in division (E)(1) or (2)
     of this section;
 
          (b) If the quorum described in division (E)(4)(a) of this section is
     not obtainable or if a majority vote of a quorum of disinterested directors
     so directs, in a written opinion by independent legal counsel other than an
     attorney, or a firm having associated with it an attorney, who has been
     retained by or who has performed services for the corporation or any person
     to be indemnified within the past five years;
 
          (c) By the shareholders;
 
          (d) By the court of common pleas or the court in which the action,
     suit, or proceeding referred to in division (E)(1)(2) of this section was
     brought.
 
          Any determination made by the disinterested directors under division
     (E)(4)(a) or by independent legal counsel under division (E)(4)(b) of this
     section shall be promptly communicated to the person who threatened or
     brought the action or suit by or in the right of the corporation under
     division (E)(2) of this section, and, within ten days after receipt of such
     notification, such person shall have the right to petition the court of
     common pleas or the court in which such action or suit was brought to
     review the reasonableness of such determination.
 
          (5)(a) Unless at the time of a director's act or omission that is the
     subject of an action, suit, or proceeding referred to in division (E)(1) or
     (2) of this section, the articles or the regulations of a corporation
     state, by specific reference to this division, that the provisions of this
     division do not apply to the corporation and unless the only liability
     asserted against a director in an action, suit, or proceeding referred to
     in division (E)(1) or (2) of this section is pursuant to section 1701.95 of
     the Revised Code, expenses, including attorney's fees, incurred by a
     director in defending the action, suit, or proceeding shall be paid by the
     corporation as they are incurred, in advance of the final disposition of
     the action, suit, or proceeding upon receipt of an undertaking by or on
     behalf of the director in which he agrees to do both of the following:
 
          (i) Repay such amount if it is proved by clear and convincing evidence
     in a court of competent jurisdiction that his action or failure to act
     involved an act or omission undertaken with deliberate intent to cause
     injury to the corporation or undertaken with reckless disregard for the
     best interests of the corporation;
 
          (ii) Reasonably cooperate with the corporation concerning the action,
     suit, or proceeding.
 
          (b) Expenses, including attorney's fees, incurred by a director,
     trustee, officer, employee, member, manager, or agent in defending any
     action, suit, or proceeding referred to in division (E)(1) or (2) of this
     section, may be paid by the corporation as they are incurred, in advance of
     the final disposition of the action, suit, or proceeding, as authorized by
     the directors in the specific case, upon receipt of an undertaking by or on
     behalf of the director, trustee, officer, member, manager, employee, or
     agent to repay such amount, if it ultimately is determined that he is not
     entitled to be indemnified by the corporation.
 
          (6)  The indemnification authorized by this section shall not be
     exclusive of, and shall be in addition to, any other rights granted to
     those seeking indemnification under the articles, the regulations, any
     agreement, a vote of shareholders or disinterested directors, or otherwise,
     both as to action in their official capacities and as to action in another
     capacity while holding their offices or positions, and shall continue as to
     a person who has ceased to be a director, trustee, officer, employee,
     member, manager, or agent and shall inure to the benefit of the heirs,
     executors, and administrators of such a person.
 
          (7)  A corporation may purchase and maintain insurance or furnish
     similar protection, including, but not limited to trust funds, letters of
     credit, or self-insurance, on behalf of or for any person who is or was a
     director, officer, employee, or agent of the corporation, or is or was
     serving at the request of the corporation as a director, trustee, officer,
     employee, member, manager, or agent of another corporation, domestic or
     foreign, nonprofit or for profit, a limited liability company, or a
     partnership, joint venture, trust, or other enterprise, against any
     liability asserted against him and incurred by him in any such capacity, or
     arising out of his status as such, whether or not the corporation would
     have the power to indemnify him against such
 
                                      II-2
<PAGE>   135
 
     liability under this section. Insurance may be purchased from or maintained
     with a person in which the corporation has a financial interest.
 
          (8)  The authority of a corporation to indemnify persons pursuant to
     division (E)(1) or (2) of this section does not limit the payment of
     expenses as they are incurred, indemnification, insurance, or other
     protection that may be provided pursuant to divisions (E)(5), (6), and (7)
     of this section. Divisions (E)(1) and (2) of this section do not create any
     obligation to repay or return payments made by the corporation pursuant to
     division (E)(5), (6), or (7).
 
          (9)  As used in division (E) of this section, "corporation" includes
     all constituent entities in a consolidation or merger and the new or
     surviving bank, so that any person who is or was a director, officer,
     employee, trustee, member, manager, or agent of such a constituent entity,
     or is or was serving at the request of such constituent entity as a
     director, trustee, officer, employee, member, manager, or agent of another
     corporation, domestic or foreign, nonprofit or for profit, a limited
     liability company, or a partnership, joint venture, trust, or other
     enterprise, shall stand in the same position under this section with
     respect to the new or surviving bank as he would if he had served the new
     or surviving bank in the same capacity.

ITEM 22.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim information.
 
     The undersigned registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through 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.
 
     The registrant undertakes that every prospectus (i) that is filed pursuant
to the immediately preceding paragraph, or (ii) that purports to meet the
requirements of section 10(a)(3) of the Securities Act of 1933 and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part 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 Securities Act of 1933, 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.
 
     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.
 
     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 registration statement through the
date of responding to the request.
 
     The undersigned registrant hereby undertakes to supply by means of a

Ladies and Gentlemen:

         Reference is made to the Registration Statement on Form S-4
("Registration Statement") to be filed by First Citizens Banc Corp ("First
Citizens") in connection with the issuance of up to 1,212,000 of its common
shares, no par value (the "First Citizens Common Shares"), upon the terms and
conditions set forth in the Merger Agreement dated November 26, 1997 by and
among First Citizens, Farmers Interim Bank ("FIB") and The Farmers State Bank of
New Washington, Ohio ("Farmers") (the "Merger Agreement"), relating to the
merger of FIB with and into Farmers. We have examined such documents and matters
of law as we have deemed necessary or appropriate for the purpose of rendering
this opinion.

         Based upon the foregoing, we are of the opinion that the First Citizens
Common Shares, when issued by First Citizens as contemplated in the Merger
Agreement and the Registration Statement, will be legally issued, fully paid and
nonassessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference of our firm under the caption "Legal
Opinions" in the prospectus/proxy statement contained therein.


                                              Respectfully submitted,

                                              SQUIRE, SANDERS & DEMPSEY L.L.P.

December 1, 1997



Board of Directors
The Farmers State Bank of New Washington, Ohio
102 S. Kibler Street
New Washington, OH

Members of the Board:

You have requested our opinion as to the federal income tax consequences of the
transactions contemplated by a certain Agreement and Plan of Reorganization
dated July 3, 1997, by and between The Farmers State Bank of New Washington
("Farmers") and First Citizens Banc Corp. ("First Citizens"), hereinafter
referred to as the "Agreement." Our opinion is made in reliance upon and is
limited to the following facts and circumstances:

                                    FACTS
                                    -----

Farmers is an Ohio chartered state banking corporation located in New
Washington, Ohio.

First Citizens is an Ohio corporation and a registered bank holding company
located in Sandusky, Ohio. First Citizens is a multi-bank holding company.

First Citizens and Farmers have only common shares outstanding. Farmers is to be
merged (the "Merger") with a newly formed wholly owned subsidiary of First
Citizens ("New Bank"), formed solely for the purpose of facilitating the
reorganization, under the charter and title of Farmers in compliance with
applicable Ohio law.

Each share of Farmers outstanding on the effective date of the Merger will be
converted into shares of common stock of First Citizens as provided by the
Agreement. The effect of the consummation of the Merger and the exchange of
shares will be that shareholders of Farmers will become shareholders of First
Citizens, and First Citizens will own, in addition to its current banking
affiliates, all of the outstanding common stock of Farmers.

The business of Farmers and First Citizens (and affiliates) will continue
substantially unchanged after the effective date of the transaction.

Page 2


No fractional shares will be issued in the transaction. In lieu thereof, holders
otherwise entitled to receive such fractional shares will be issued cash.

We are not aware and have been advised by the management of Farmers that they
have no knowledge of any plan or intention on the part of shareholders of
Farmers to sell or otherwise dispose of an amount of the First Citizens shares
to be received in the transaction, which could reduce Farmers' shareholders'
ownership of First Citizens shares after the Merger to shares having an
aggregate value as of the date of the transaction, of less than eighty percent
(80%) of the value of all the formerly outstanding shares of Farmers as of the
same date.

The Merger will be carried out pursuant to and in accordance with all applicable
corporate and banking laws relating to the transaction. On the effective date
Farmers will succeed to all assets of, and will be liable for the liabilities
of, New Bank, then existing or arising as a result of the transactions and First
Citizens will operate Farmers as a wholly owned subsidiary.

Following the consummation of the Merger, First Citizens will continue to
operate the business of Farmers in substantially the same manner.

Arms-length negotiations were carried on between the management of First
Citizens and management of Farmers which led to the Agreement and fixed the
terms of the transactions. Consideration was given to both financial and
nonfinancial factors involved in the transaction and the business benefits from
the transaction were discussed and considered by the parties.

In the opinion of the management of First Citizens and Farmers, Farmers'
employees and customers will benefit from the affiliation. It is also expected
that the transaction will better enable the resulting corporation to compete
with other financial institutions.

                                     OPINION
                                     -------

Based upon the above, it is our opinion that the Agreement will have the
following federal income tax consequences:

1.       The merger of New Bank with and into Farmers will constitute a
         "Statutory Merger" within the meaning of Section 368(a)(1)(A) and
         (a)(2)(E) of the Internal Revenue Code of 1986, as amended, (the
         "Code") and New Bank, Farmers and First Citizens will each be a "party
         to a reorganization" within the meaning of Section 368(b) of the Code.

2.       No gain or loss will be recognized by Farmers as a result of the Merger
         of New Bank with and into Farmers. Section 361(a) and 357(a) of the
         Code.

3.       No gain or loss will be recognized by Farmers' shareholders who
         exchanged their respective shares solely for First Citizens shares.
         Section 354(a) of the Code.

4.       The basis of the First Citizens shares received by Farmers'
         shareholders in exchange for their shares will be the same as the basis
         for federal income tax purposes in the shares exchanged therefor,
         respectively. Section 358(a) of the Code.

5.       The holding period of the First Citizens shares received by Farmers'
         shareholders will include the period during which shares exchanged
         therefor were held, provided such shares were held as a capital asset
         by such shareholders as of the date of the exchange.
         Section 1223(1) of the Code.

6.       The payment of cash in lieu of fractional shares for the purpose of
         mechanically rounding off the fractions resulting from the exchange,
         will, in each instance, constitute a distribution not essentially
         equivalent to a dividend within the meaning of Section 302(b)(1) of the
         Code. The amount received will be treated as a distribution in full
         payment in exchange for the shareholders' fractional share of interest
         under Section 302(a) of the Code.

This letter is solely for your information and use, and except: (i) for its
reliance upon by Farmers and its stockholders; and (ii) to the extent that such
may be referred to in the Registration Statement and filed with the Securities
and Exchange Commission as an exhibit to same, it is not to be used, circulated,
quoted or otherwise referred to for any other purpose, or relied upon by any
other person, for whatever reason without our prior written consent.

Very truly yours,
