                          To be Held on _________, 1996

         Notice is hereby given that the Special Meeting of Stockholders (the
"Meeting") of CitNat Bancorp, Inc. ("CitNat" or the "Company") will be held at
_________________________________ on ________, 1996 at ____ A.M.

         A Proxy Card and a Proxy Statement for the Meeting are enclosed.

         The Meeting is for the purpose of considering and acting upon:

                  1. A proposal to adopt, pursuant to Sections 1701.78 and
         1701.831 of the Ohio Revised Code, a Merger Agreement (the "Merger
         Agreement"), dated March 14, 1996, by and between CitNat and Security
         Banc Corporation ("Security"), a copy of which is included in the
         accompanying Proxy Statement-Prospectus as Appendix A. As more fully
         described in the Proxy Statement-Prospectus, the Merger Agreement
         provides for the Merger of CitNat with and into Security, with Security
         surviving the transaction. Pursuant to the Merger Agreement, all of the
         outstanding common shares of CitNat will be converted into common
         shares of Security in accordance with the Exchange Ratio (as defined in
         the Merger Agreement).

                  2. Such other matters as may properly come before the Meeting,
         or any adjournments thereof. The Board of Directors is not aware of any
         other business to come before the Meeting.

         Notice is also given that CitNat stockholders have the right to dissent
and demand an appraisal of the value of their common shares in the event the
Merger Agreement is adopted and the merger consummated. The right of any
dissenting shareholder to receive the value of his common shares through the
statutory appraisal process is contingent upon strict compliance with the
procedures set forth in Section 1701.85 of the Ohio General Corporation Law, the
relevant portions of which are attached as Appendix C to the accompanying Proxy
Statement-Prospectus.

         Any action may be taken on the foregoing proposal at the Meeting on the
date specified above, or on any date or dates to which the Meeting may be
adjourned. Stockholders of record at the close of business on _______, 1996 will
be entitled to vote at the Meeting, and any adjournments thereof. A complete
list of stockholders entitled to vote at the Meeting will be available at the
Meeting.

         You are requested to complete and sign the enclosed Form of Proxy which
is solicited on behalf of the Board of Directors, and to mail it promptly in the
enclosed envelope. The Proxy will not be used if you attend and vote at the
Meeting in person. Attendance at the Meeting will not, in and of itself,
constitute a revocation of a proxy.

                                    By Order of the Board of Directors

                                    James R. Wilson, President, Chief Executive

           COMPLIANCE WITH THE OHIO CONTROL SHARE ACQUISITION STATUTE

         Consummation of the proposed merger of CitNat with and into Security in
accordance with the terms of the Merger Agreement requires compliance with the
Ohio Control Share Acquisition Act (the "Acquisition Act") The Acquisition Act
requires the advance approval of the stockholders of an Issuing Public
Corporation prior to the purchase of a controlling interest in such corporation.
CitNat is an Issuing Public Corporation within the meaning of the Acquisition
Act and therefore the transactions contemplated by the Merger Agreement must be
approved under the Acquisition Act. A vote For the Merger will also constitute
an affirmative vote to approve the acquisition of 100% of the outstanding shares
of CitNat Common Stock by Security as required by the Acquisition Act.

                                        6
<PAGE>   11
Presented below is Security's Acquiring Person Statement as required by the
Acquisition Act. Security submitted its Acquiring Person Statement to CitNat on
the date this Proxy Statement was first mailed to CitNat stockholders. Approval
under the Acquisition Act requires the favorable vote of a majority of the
shares entitled to vote in the election of directors as well as a majority vote
of such shares excluding any shares held by interested stockholders, which are
defined to include Security, any corporate officer of CitNat and any employee of
CitNat who is also a director of CitNat. In addition "interested shares" are
defined to include those acquired by any person after the first date of public
disclosure (March 15, 1996) of the Merger and prior to the date of the Special
Meeting, provided such person is paid over $250,000 for such purchased shares or
such purchased shares represents greater than .05% of the outstanding shares of
the Issuing Public Corporation. As of the Record Date, Security owns no shares
of CitNat. Officers and employees of CitNat who are interested shareholders
within the meaning of the Acquisition Act owned 63,122 shares of CitNat. Neither
CitNat nor Security are aware of any other shares of CitNat Common Stock which
could be considered as held by an interested shareholder as defined by the
Acquisition Act. Therefore approval of the proposed acquisition of a controlling
interest in CitNat by Security under the provisions of the Acquisition Act
requires the affirmative vote of 195,060 shares which represents a majority of
the shares entitled to vote in the election of directors and 163,699 shares in
connection with the vote which excludes interested shares, as defined by the
Acquisition Act.

rendered its opinion to the Board of Directors of CitNat to the effect that the
consideration to be received by the stockholders of CitNat upon consummation of
the CitNat Merger is fair and equitable, from a financial perspective, to the
holders of CitNat Common Stock. The opinion of PBS, which is attached as
Appendix B to this Proxy Statement-Prospectus, sets forth the assumptions made,

affiliates for distribution (which Security has not agreed to provide), (b)

exemption from registration requirements under the Securities Act. For Security

PENDING ACQUISITIONS

         On April 22, 1996, Security executed a definitive Agreement and Plan of
Reorganization with Third Financial Corp., Piqua, Ohio ("Third" and the "Third
Agreement"). Pursuant to the terms of the Third Agreement, stockholders of Third
will exchange all of the outstanding shares of Third Common Stock on the
effective date of the acquisition of Third by Security (the "Third Merger") for
$40,050,000, in cash, in the aggregate, subject to adjustment. Third is a
Delaware corporation and is a savings and loan holding company which owns as its
principal asset all of the outstanding capital stock of Third Savings and Loan
Association, Piqua, Ohio. The Third Merger will be accounted for as a purchase
under the provisions of Accounting Principles Bulletin 16 and is expected to be
completed in the fourth quarter of 1996.

SELECTED FINANCIAL DATA

         The following unaudited tables present selected historical financial
information and selected pro forma combined financial information for Security
and CitNat. This information should be read in conjunction with the historical
and pro forma financial statements and notes thereto included elsewhere in or
incorporated by reference to this Prospectus-Proxy Statement. The pro forma
combined financial information gives effect to the Merger. The pro forma
combined financial information may not be indicative of the results that
actually would have occurred if the Merger had been in effect on the dates

financial information has been prepared on the assumption that the Merger will
be accounted for under the pooling of interests method of accounting and also

                                 PROPOSED MERGER

         This section of the Proxy Statement-Prospectus describes certain
aspects of the proposed Merger. The following description does not purport to be
complete and is qualified in its entirety by reference to the Agreement which is
attached as Exhibit A to this Proxy Statement-Prospectus and is incorporated
herein by reference.

BACKGROUND AND REASONS FOR THE MERGER

         CitNat. On December 28, 1995, the management of CitNat met to discuss
an indication of interest received from Security with respect to a possible
merger transaction (the "Merger"). At that time the the Board of Directors
authorized CitNat's management to pursue preliminary discussions with Security
with a view to obtaining information regarding the Merger

         In February of 1996 the Board of Directors of CitNat engaged 
Professional Bank Services, Louisville, Kentucky, ("PBS") as their financial
advisor to provide an opinion to CitNat as to the fairness of the transaction
to the stockholders of CitNat from a financial standpoint, and also to conduct
a due diligence review of Security. During the following weeks, CitNat and
Security and their respective financial and legal advisors engaged
intermittently in negotiations concerning the terms of the Merger and each of
Security and CitNat performed due diligence reviews of the other.

         On February 20, 1996, CitNat's Board of Directors met to consider the
proposed terms of the Merger. This Meeting included a presentation by PBS and
CitNat's legal advisor, which included summaries of financial and 

                                       23
<PAGE>   28
valuation analyses, the terms of the proposed acquisition, regulatory and
accounting matters, the due diligence findings of CitNat's management and
advisors, and PBS's oral opinion relating to the fairness of the Merger to the
stockholders of CitNat from a financial perspective. At the conclusion of this
meeting, the Board of Directors of CitNat authorized CitNat's management to
continue to negotiate the terms of a definitive agreement with Security.

         On March 12, 1996, CitNat's Board of Directors again met with PBS and
CitNat's legal advisors to discuss and review the proposed terms of the Merger.
Based upon the following factors, CiNat's Board of Directors voted unanimously
to approve the Merger: (1) PBS's opinion that the terms of the Merger are fair
to the stockholders of CitNat from a financial perspective; (2) the overall
financial terms of the Merger; (3) Security's representations with respect to
the operation of CitNat and Citizens Bank after the Merger; (4) the short-term
and long-term prospects of CitNat; (5) current long-term industry developments
and trends; and (6) competitive factors.

         Security. The Board of Directors of Security has concluded that the
Merger would be in the best interests of Security and its stockholders. Numerous
factors were considered by the Board of Directors of Security in approving and
recommending the terms of the Merger. These factors included information
concerning the financial condition, results of operations, and prospects of
Security and CitNat; the capital adequacy of the resulting entity; the
composition of the businesses of the two organizations in the rapidly changing
banking and financial services industry; the historical and current market
prices of each company's stock and of certain other bank holding companies whose
securities are publicly traded; the relationship of the consideration to be paid
in the Merger to such market prices and to the book value and earnings per share
of CitNat and the financial terms of certain other recent business combinations
in the banking industry. In addition the Board of Directors considered the
advise of its financial advisor, Austin Associates, Inc.

         The Board of Directors of Security believes that combining with CitNat
which has established banking operations in Urbana, Ohio is a natural and
desirable extension of Security's market area. The Board of Directors of
Security also believes that the consolidation of resources by reason of the
Merger will enable the resulting organization to provide a wider and improved
array of financial services to customers and to achieve added flexibility in
dealing with the changing competitive environment in the financial services
industry.

RECOMMENDATION OF THE CITNAT BOARD OF DIRECTORS

         THE BOARD OF DIRECTORS OF CITNAT UNANIMOUSLY RECOMMENDS THAT THE
STOCKHOLDERS OF CITNAT VOTE FOR APPROVAL OF THE AGREEMENT.

OPINION OF CITNAT'S FINANCIAL ADVISOR

         Professional Bank Services, Inc. ("PBS") was engaged by CitNat to
advise the CitNat Board of Directors as to the fairness of the consideration,
from a financial perspective, to be paid by Security to CitNat shareholders as
set forth in the Agreement. PBS is a bank consulting firm with offices in
Louisville, Nashville, Indianapolis, Washington, D.C., and Ocala, Florida. As
part of its investment banking business, PBS is regularly engaged in reviewing
the fairness of financial institution acquisition transactions from a financial
perspective and in the valuation of financial institutions and other businesses
and their securities in connection with mergers, acquisitions, estate
settlements. and other transactions. Neither PBS nor any of its affiliates has a
material financial interest in CitNat or Security. PBS was selected to advise
the CitNat Board of Directors based upon PBS's familiarity with Ohio financial
institutions and knowledge of the banking industry as a whole.

         PBS performed certain analyses described herein and discussed the range
of values for CitNat resulting from such analyses with the Board of Directors of
CitNat in connection with its advice as to the fairness of the consideration to
be paid by Security.

         A Fairness Opinion of PBS was delivered to the Board of Directors of
CitNat on February 20, 1996, at a special meeting of the Board of Directors. A
copy of the Fairness Opinion, which includes a summary of the assumptions made
and information analyzed in deriving the Fairness Opinion, is attached as
Appendix B to this Proxy Statement-Prospectus and should be read in its entirety

                                       24
<PAGE>   29
         In arriving at its Fairness Opinion, PBS reviewed certain publicly
available business and financial information relating to CitNat and Security.
PBS considered certain financial and stock market data of CitNat and Security,
compared that data with similar data for certain other publicly-held bank
holding companies and considered the financial terms of certain other comparable
bank transactions in the states of Ohio, Indiana and Kentucky ("Midwest Region")
that had recently been effected. PBS also considered such other information,
financial studies, analyses and investigations and financial, economic and
market criteria that it deemed relevant. In connection with its review, PBS did
not independently verify the foregoing information and relied on such
information as being complete and accurate in all material respects. Financial
forecasts prepared by PBS were based on assumptions believed by PBS to be
reasonable and to reflect currently available information. PBS did not make an
independent evaluation or appraisal of the assets of CitNat or Security.

         As part of preparing the fairness opinion, PBS performed a due
diligence review of Security and its affiliate bank, Security National Bank,
Springfield, Ohio (the "Bank"). As part of the due diligence, PBS reviewed
minutes of Security's and the Bank's Board of Directors meetings; reports filed
with the Securities and Exchange Commission by Security on Forms 10-K and 10-Q
for the year ending December 31, 1994 and quarter ending September 30, 1995;
reports of independent auditors for the years ending December 31, 1994 and 1995;
1994 and 1995 Office of the Comptroller of the Currency ("OCC") and Federal
Reserve Reports of Examination; Uniform Bank Performance Reports; investment
security holdings; listing of pending litigation provided by independent
counsel; analysis and calculation of the allowance for loan and lease losses as
of December 31, 1995; and internally identified special assets and related
reports as of December 31, 1995.

         PBS also interviewed senior management, external auditors and general
counsel of Security regarding operations, performance and the future prospects
of Security. PBS compared the historical common stock market activity of
selected financial institutions headquartered in Ohio to Security.

         PBS reviewed and analyzed the historical performance of CitNat and its
wholly owned subsidiary Citizens National Bank of Urbana, Urbana, Ohio
("Citizens") contained in: audited financial statements dated December 31, 1992,
1993, 1994 and 1995; December 31, 1995 Consolidated Reports of Condition and
Income filed with the Federal Deposit Insurance Corporation by Citizens;
September 30, 1995 Uniform Bank Performance Report of Citizens; historical
common stock trading activity of CitNat; and the premises and other fixed
assets. PBS reviewed and tabulated statistical data regarding the loan
portfolio, securities portfolio and other performance ratios and statistics.
Financial projections were prepared and analyzed as well as other financial
studies, analyses and investigations as deemed relevant for the purposes of this
opinion. In review of the aforementioned information, PBS took into account its
assessment of general market and financial conditions, its experience in other
similar transactions, and its knowledge of the banking industry generally.

         In connection with rendering the Fairness Opinion and preparing its
various written and oral presentations to CitNat's Board of Directors, PBS
performed a variety of financial analyses, including those summarized herein.
The summary does not purport to be a complete description of the analyses
performed by PBS in this regard. The preparation of a fairness opinion involves
various determinations as to the most appropriate and relevant methods of
financial analysis and the application of these methods to the particular
circumstances and therefore, such an opinion is not readily susceptible to
summary description. Accordingly, notwithstanding the separate factors
summarized below, PBS believes that its analyses must be considered as a whole
and that selecting portions of its analyses and of the factors considered by it,
without considering all analyses and factors, could create an incomplete view of
the evaluation process underlying its opinion. In performing its analyses, PBS
made numerous assumptions with respect to industry performance, business and
economic conditions and other matters, many of which are beyond CitNat's or
Security's control. The analyses performed by PBS are not necessarily indicative
of actual values or future results, which may be significantly more or less
favorable than suggested by such analyses. In addition, analyses relating to the
values of businesses do not purport to be appraisals or to reflect the process
by which businesses actually may be sold.

         Acquisition Comparison Analysis: In performing this analysis, PBS
reviewed bank acquisition transactions in the states of Ohio, Indiana, and
Kentucky which encompass the "Midwest Region." There were 138 bank acquisition
transactions in the Midwest Region announced since 1989 for which detailed
financial information 

                                       25
<PAGE>   30
was available. The purpose of the analysis was to obtain an evaluation range
based on these regional acquisition transactions. Median multiples of earnings
and book value implied by the comparable transactions were utilized in obtaining
a range for the acquisition value of CitNat. In addition to reviewing recent
Midwest Region bank transactions, PBS performed separate comparable analyses for
acquisitions of Midwest Region banks which, like CitNat. had an equity-to-asset
ratio greater than 10%, were located in Ohio and had assets between $75.0 and
$250.0 million. Median values for the 138 Midwest Region acquisitions expressed
as multiples of both book value and earnings were 1.62 and 14.7, respectively.
The median multiples of book value and earnings for acquisitions of Midwest
Region banks with equity-to-asset ratios greater than 10.0% were 1.58 and 16.82,
respectively. For acquisitions of Midwest Region banks located in the state of
Ohio, the median multiples were 1.69 and 12.40, respectively. For acquisitions
of Midwest Region banks with assets between $75.0 and $250.0 million the median
multiples were 1.66 and 16.21, respectively. Utilizing a Security common stock
price of $28.75 per share, the value of the proposed transaction would equal
$62.40 per CitNat common share. This represents a multiple of book value and a
multiple of earnings of 1.40 and 15.29 respectively.

         Pro Forma Merger Analysis: PBS compared the historical performance of
CitNat to that of Security and other regional bank holding companies. This
included, among other things, a comparison of profitability, asset quality and
capital adequacy measures. In addition, the contribution of each of CitNat and
Security to the income statement and balance sheet of the pro forma combined
company was analyzed.

         The effect of the affiliation on the historical and pro forma financial
data of CitNat, as well as the projected financial data prepared by PBS, was
analyzed. CitNat's historical financial data was compared to pro forma combined
historical and projected earnings, book value and dividends per share as well as
other measures of profitability, capital adequacy and asset quality.

         The Fairness Opinion is directed only to the question of whether the
consideration to be received by CitNat's shareholders under the Agreement is
fair and equitable from a financial perspective and does not constitute a
recommendation to any CitNat shareholder to vote in favor of the Affiliation. No
limitations were imposed on PBS regarding the scope of its investigation or
otherwise by CitNat or any of its affiliates.

         Based on the results of the various analyses described above, PBS
concluded that the consideration to be received by CitNat shareholders under the
Agreement is fair and equitable from a financial perspective to the shareholders
of CitNat.

         PBS will receive a fee in the amount of $22,500 for all of its services
performed in connection with the Affiliation, including rendering the Fairness
Opinion. In addition, CitNat has agreed to indemnify PBS and its directors,
officers and employees, from liability in connection with the Affiliation, and
to hold PBS harmless from any losses, actions, claims, damages, expenses or
liabilities related to any of PBS' acts or decisions made in good faith and in
the best interest of CitNat.

TERMS OF THE MERGER

         At the Effective Time (as defined below), CitNat will merge with
Security with the result that Citizens Bank will become a wholly owned
subsidiary bank of Security. At the Effective Time, the directors and officers
of Citizens Bank serving in such capacity immediately prior to the Effective
Time shall continue to be the directors and officers of Citizens Bank. In
addition, at the Effective Time, the Agreement provides that one additional
person from CitNat will become a member of the Board of Directors of Security.
The Board of Directors of Security has determined that such person will be James
R. Wilson, the President, Chief Executive Officer and a director of CitNat.

         At the Effective Time, all of the outstanding shares and options to
purchase shares of CitNat Common Stock will be converted into shares of Security
Common Stock in accordance with the terms of the Agreement and the Exchange
Ratio as defined by the Agreement. The Exchange Ratio provides that each
outstanding share of CitNat Common Stock shall be exchanged for and converted
into the right to receive 2.1842437 shares of Security 

                                       26
<PAGE>   31
Common Stock and each outstanding option to purchase one share of CitNat Common
Stock will be exchanged for and converted into the right to receive .7791283
shares of Security Common Stock as set forth in the Agreement. In the
transaction, Security expects to issue 908,072 shares of Security Common Stock
in the Merger.

          No fractional shares of Security Common Stock will be issued in the
Merger. Rather, each holder of CitNat Common Stock who otherwise would have been
entitled to a fraction of a share of Security Common Stock shall receive in lieu
thereof cash, without interest, in an amount determined by multiplying the
fractional share interest to which such holder would otherwise be entitled by
the average of the bid and asked closing price on the effective date of the
Merger as reported by J. Wolf & Company, a division of McDonald & Company
Securities, Inc.

EFFECTIVE TIME OF THE MERGER

          Subject to satisfaction or waiver of all other conditions contained in
the Agreement, the Merger, will become effective on the first business day of
the next calendar month after the later to occur of (i) approval of the
Agreement by the Federal Reserve Board and (ii) approval of the Merger by the
stockholders of CitNat. The Merger will become effective on the first day of the
second calendar month following the events specified in (i) and (ii) above if
the last of such events occurs after the twentieth of the month. An earlier date
may be specified by Security or another time may be agreed upon in writing by
the parties. Upon the filing of executed Articles of Merger, with the Secretary
of State in Ohio the Merger will become effective at such time as is specified
in the Articles of Merger (the "Effective Time"). Subject to the conditions
contained in the Agreement, the Effective Time is currently expected to occur
during the end of the third quarter or the beginning of the fourth quarter of
1996.

SURRENDER OF CITNAT CERTIFICATES

         As soon as practicable after the Effective Time of the Merger Security
is required by the Agreement to mail to each holder of record of CitNat Common
Stock a letter of transmittal and instructions for use in surrendering such
holder's CitNat Common Stock certificates.

         CITNAT STOCKHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES UNTIL
THEY RECEIVE A LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS FROM SECURITY.

         Upon surrender to Security of one or more certificates of CitNat Common
Stock together with a properly completed letter of transmittal, Security will
issue and deliver to the holder of record of CitNat Common Stock, a certificate
representing the number of shares of Security Common Stock to which the holder
is entitled and, where applicable, a check for the amount representing any
fractional share interest.

         All Security Common Stock issued pursuant to the Agreement will be
issued as of the Effective Time. No dividends or other distributions declared
with respect to Security Common Stock payable to former holders of CitNat Common
Stock, pursuant to the Merger and payable to the holders thereof after the
Effective Time shall be paid until such holder surrenders such holder's CitNat
Common Stock certificates. Subject to the effect of applicable laws, after the
surrender and exchange of such certificates, the holder of certificates for
shares of Security Common Stock into which the shares of CitNat Common Stock
shall have been converted shall be entitled to receive any dividends or other
distributions, but without any interest, which previously became payable by
Security with respect to the shares of CitNat Common Stock represented by such
certificate or certificates.

         In the case of any lost, stolen or destroyed CitNat Common Stock
certificate, Security will issue a new certificate representing shares of
Security Common Stock and a check for the cash into which a fractional share of
CitNat Common Stock shall have been converted only if Security receives: (i)
evidence to the reasonable satisfaction of Security that such certificate has
been lost, wrongfully taken or destroyed, (ii) such indemnity agreement as
reasonably may be requested by Security to save it harmless, and (iii) evidence
satisfactory to it of ownership of CitNat Common Stock for which the certificate
has been lost, wrongfully taken or destroyed.

to be performed by them under the Agreement; (vi) the receipt by CitNat and
Security and the continuing effectiveness of opinion of counsel as to certain
federal income tax consequences of the respective Merger; (vii) the receipt of
all consents or approvals from third parties required under agreements for
consummation of the Merger other than those agreements for which failure to
obtain such consents or approval would not have a material adverse effect on
CitNat; (viii) that no event shall have occurred, which, in the reasonable
opinion of Security and its auditors, would prevent the Merger from being
accounted for as a pooling of interests; (ix) the absence of any material
adverse change since December 31, 1995, in the financial condition, results of
operation or business of CitNat and Security in each case, together with their
respective subsidiaries taken as a whole; (x) the absence of any material
action, suit or proceeding commenced against CitNat and Security with respect to
the Merger seeking to restrain, enjoin, prevent, change or rescind the
transaction contemplated by the Agreements or questioning the validity or
legality of any such transaction; (xi) the receipt by CitNat and Security of
opinions of counsel as provided in the Agreement; (xii) the receipt by CitNat of
an opinion, from its financial advisor, dated within two days of the Proxy
Statement-Prospectus, that the Merger is fair to the holders of CitNat Common
Stock from a financial point of view; and (xiii) that not more than ten percent
of the voting power of the issued and outstanding shares of CitNat Common Stock
shall have taken steps, at the time the Merger shall become effective, to
perfect their rights as dissenting shareholders under Ohio law.

         The consummation of the Merger is conditioned upon the determination
that the Merger will be accounted for under the pooling of interests method of
accounting. In the event the Merger did not qualify for pooling accounting
treatment, but the parties determined to consummate the Merger and to waive the
condition, the Merger would not be consummated without a resolicitation of the
vote of stockholders of CitNat. In such an event, the revised pro forma
financial information would be materially different than those presented
elsewhere herein.

         In addition, unless waived, each party's obligation to consummate the
Merger is subject to performance by the other party of its obligations under the
respective Agreement and the receipt of certain certificates from the other
party.

REGULATORY APPROVAL

         The Merger is subject to prior approval by the Federal Reserve Board
under the Bank Holding Company Act of 1956, as amended ("BHC Act"), which
requires that the Federal Reserve Board take into consideration the financial
and managerial resources and future prospects of the respective institutions and
the convenience and needs of the communities to be served. The BHC Act prohibits
the Federal Reserve Board from approving the Merger if it would result in a
monopoly or be in furtherance of any combination or conspiracy to monopolize or
to attempt to monopolize the business of banking in any part of the United
States, or if its effect in any section of the country may

                                       28
<PAGE>   33
be substantially to lessen competition or to tend to create a monopoly, or if it
would in any other manner be a restraint of trade, unless the Federal Reserve
Board finds that the anti-competitive effects of the Merger are clearly
outweighed in the public interest by the probable effect of the transaction in
meeting the convenience and needs of the communities to be served. The Federal
Reserve Board has the authority to deny an application if it concludes that the
combined organization would have an inadequate capital position.

         Under the BHC Act, the Merger may not be consummated until the 30th day
following the date of Federal Reserve Board approval, during which time the
United States Department of Justice may challenge the Merger on antitrust
grounds. The commencement of an antitrust action would stay the effectiveness of
the Federal Reserve Board's approval unless a court specifically orders
otherwise. The BHC Act provides for the publication of notice and public comment
on the application and authorizes the regulatory agency to permit interested
parties to intervene in the proceedings.

         Security filed an application with the Federal Reserve Bank of
Cleveland (the "Federal Reserve Bank") on April 18, 1996, seeking approval of
the Merger. On May 30, 1996, such application was approved.

         The approvals of the Federal Reserve Board is not to be interpreted as
the opinion of such regulatory authority that the Merger is fair to the
stockholders of CitNat from a financial point of view or that such regulatory
authority has considered the adequacy of the terms of the Merger. An approval by
such regulatory authority in no way constitutes an endorsement or a
recommendation of the Merger by the Federal Reserve Board.

         There can be no assurance that the Department of Justice will not
challenge the Merger or if such a challenge is made, as to the result thereof.

         Other than the regulatory approvals described herein and required
compliance with certain federal and state securities laws by Security in
connection with its issuance of shares of Security Common Stock in connection
with the Merger with which Security will comply, Security and CitNat are not
aware of any other governmental approvals or actions that are required for
consummation of the Merger except as described above. Should any other approval
or action be required, it is presently contemplated that such approval or action
would be sought. There can be no assurance that any such approval or action, if
needed, could be obtained and, if such approvals or actions are obtained, there
can be no assurance as to the timing thereof.

CONDUCT OF BUSINESS PENDING THE MERGER

         Under the Agreement CitNat and Security are generally obligated to (and
to cause their respective subsidiaries to) operate their respective businesses
only in the usual and ordinary course consistent with past practices; use
reasonable efforts to keep in force current insurance coverage; refrain from any
change in their methods of accounting or certain other policies and refrain from
taking any action that would adversely affect or delay regulatory approval of
the Agreement; give the other party and its representatives access to
information concerning its affairs as may be reasonably requested; and with
respect to CitNat refrain from paying cash dividends except as permitted under
the Agreement, see "Dividends."

DIVIDENDS

         Under the Agreement, CitNat may not pay cash dividends prior to the
Effective Time of the Merger except for a semi-annual cash dividend at the rate
of $0.45 per share payable in July 1996, and in the event the Merger shall not
have consummated prior to the record date for the determination of stockholders
entitled to Security's normal cash dividend payable in December of each year,
then an additional semi-annual cash dividend at the rate of $0.45 in December of
1996.

TERMINATION, AMENDMENT AND WAIVER

         The Agreement may be terminated at any time prior to the Effective Time
whether before or after approval of the matters presented by the stockholders of
CitNat: (i) by mutual consent of the Boards of Directors of CitNat 

                                       29
<PAGE>   34
and Security; (ii) by either party to the Merger if all required regulatory
approvals are not received; (iii) by the Board of Directors of either party if
there has been a willful breach of any representation, warranty, covenant or
agreement by the other party which is not cured after 10 days' written notice;
(iv) by either party if the required vote of CitNat stockholders is not
received; or (v) by the Board of Directors of either party if the Merger is not
consummated by December 31, 1996.

         The Agreement may not be amended except in writing signed on behalf of
both parties, whether before or after approval of the matters presented in
connection with the Merger by the stockholders of CitNat. At any time prior to
the Effective Time, either party to the Agreement may, to the extent legally
allowed, extend the time for performance of any of the obligations of the other
party, waive any inaccuracies in representations and warranties of the other and
waive compliance with any of the agreements or conditions of the Agreement.

TERMINATION FEE

         If CitNat stockholders fail to approve the Agreement and at such time
there is either: (i) a publicly announced offer by a third party to acquire
CitNat at a price at the time of the announcement of such offer equal in value
to at least $62.75 per share of CitNat Common Stock, or (ii) The Board of
Directors of CitNat fails to favorably recommend approval of the Merger, and
within one year after the termination of the Agreement CitNat is acquired, then,
subject to certain other conditions set forth in the Agreement, CitNat shall pay
a termination fee to Security of $1,000,000.

MANAGEMENT AND OPERATIONS AFTER THE MERGER

         As a result of the Merger, Citizens Bank will become a wholly owned
subsidiary of Security. Security expects to continue to operate Citizens Bank at
its present locations. Immediately after the Effective Time of Merger, the Board
of Directors of Citizens Bank shall be comprised of all those persons serving as
a director of Citizens Bank immediately prior to the Effective Time of the
Merger. The Board of Directors of Security after the Effective Time of the
Merger shall be comprised of all those persons serving as a director of Security
immediately prior to the Effective Time plus one additional person to be added
to the Board of Directors from CitNat. Security has determined that such person
will be James R. Wilson, President, Chief Executive Officer and a Director of
CitNat.

                                       30
<PAGE>   35
INTERESTS OF CERTAIN PERSONS IN THE MERGER

         As of the Record Date, executive officers and directors of CitNat are
or may be deemed to be the beneficial owners of less than 1% of the outstanding
shares of Security Common Stock and executive officers and directors of Security
beneficially own no shares of CitNat Common Stock. Certain executive officers
and directors of CitNat hold options to purchase 71,820 shares of CitNat Common
Stock at a price of $40 per share. These options were granted to such persons in
connection with CitNat's Incentive Stock Option Plan. It is not expected that
such options will be exercised prior to the effective date of the Merger. The
Agreement provides that all of such options shall be exchanged for and converted
into the right to receive .7791283 shares of Security Common Stock at the
Effective Time of the Merger.

EFFECT ON EMPLOYEE BENEFIT PLANS

         CitNat. The Agreement provides that each employee of Citizens Bank will
be eligible to participate in the employee benefit plans of Security immediately
upon the consummation of the Merger. For purposes of eligibility and vesting in
Security's employee benefits, employees of CitNat and Citizens Bank will be
given credit for their years of service as employees of CitNat and Citizens
Bank. The CitNat Employee Stock Ownership Plan and its related Trust ("ESOP")
will be terminated or amended at or after the Effective Time of the Merger as
directed by Security. If the ESOP is terminated, effective as of such
termination date each participant with an account balance under the ESOP shall
become fully vested in such account regardless of his vested position under the
ESOP.

         Security. Employee benefits of Security will not be changed as a result
of the Merger.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The following is a summary description of the anticipated federal
income tax consequences of the Merger to holders of Security Common Stock and
CitNat Common Stock and to Security and CitNat. The summary is not a complete
description of the federal income tax consequences of the Merger. Each
stockholder's individual circumstances may affect the tax consequences of the
Merger to such stockholder.

         Neither Security nor CitNat has requested or will receive an advance
ruling from the Internal Revenue Service (the "Service") as to the tax
consequences of the Merger. With respect to the Merger, Security and CitNat have
received an opinion from special counsel to Security, Werner & Blank Co., L.P.A.
This tax opinion is based upon certain representations made by Security and
CitNat and upon the current law and the current judicial and administrative
interpretations thereof. This opinion will not be binding on the Service or any
court. Consequently, there can be no assurance that the tax consequences set
forth below will continue as described herein, nor can any assurance be given
that the issues discussed below will not be challenged by the Service, or, if so
challenged, will be decided favorably to the parties to the Merger or their
stockholders.

         Subject to the foregoing, the opinions of Werner & Blank Co., L.P.A.,
are substantially as follows:

                  (i) Since the merger of CitNat with and into Security
         qualifies as a statutory merger under applicable federal law, the
         Merger will qualify as a "reorganization" within the meaning of Section
         368(a)(1)(A) of the Internal Revenue Code of 1986, as amended (the
         "Code");

                  (ii) No gain or loss will be recognized by CitNat or Security
         upon merger of CitNat with and into Security;

                  (iii) No gain or loss will be recognized by the CitNat
         stockholders who exchange, pursuant to the Merger, their shares of
         CitNat Common Stock solely for shares of Security Common Stock;

                                       31
<PAGE>   36
                  (iv) The federal income tax basis of the Security Common Stock
         to be received by the CitNat stockholders in Merger, including
         fractional share interests, will be the same as the federal income tax
         basis of such CitNat Common Stock surrendered therefor;

                  (v) The holding period of the Security Common Stock to be
         received by the CitNat stockholders in the Merger will include the
         period during which the CitNat Common Stock surrendered was held as a
         capital asset on the Effective Date of the Merger;

                  (vi) The payment of cash in lieu of fractional share interests
         of Security Common Stock will be treated as if the fractional shares
         were distributed as part of the Merger and then were redeemed by
         Security. These cash payments will be treated as having been received
         as distributions in full payment in exchange for the stock redeemed as
         provided in Section 302(a) of the Code; and

                  (vii) Where a CitNat stockholder dissents to the Merger, and
         such stockholder receives solely cash in exchange for his or her CitNat
         Common Stock, such cash will be treated as having been received by such
         stockholder as a distribution in redemption of his or her shares
         subject to the provisions and limitations of Section 302 of the Code.

         THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE HAS NOT BEEN VERIFIED
WITH THE INTERNAL REVENUE SERVICE AND IS BASED UPON THE FEDERAL INTERNAL REVENUE
CODE AS IN EFFECT ON THE DATE OF THIS PROXY STATEMENT-PROSPECTUS WITHOUT
CONSIDERATION OF ANY STATE LAWS OR THE PARTICULAR FACTS OR CIRCUMSTANCES OF ANY
CITNAT STOCKHOLDER.

         BECAUSE OF THE COMPLEXITY OF THE FEDERAL, STATE AND LOCAL TAX LAWS IT
IS RECOMMENDED THAT STOCKHOLDERS AND OPTIONHOLDERS OF CITNAT CONSULT THEIR OWN
TAX ADVISORS REGARDING THE TAX CONSEQUENCES RESULTING FROM THE MERGER.

ACCOUNTING TREATMENT

         The Agreement provides that consummation of the Merger is conditioned
upon the receipt by Security of assurances, satisfactory to it, that the Merger
qualifies for accounting treatment as a pooling of interests if consummated in
accordance with the Agreement. Under the pooling of interests method of
accounting, the historical basis of the assets and liabilities of Security and
CitNat will be combined at the Effective Time and carried forward at their
previously recorded amounts, and the stockholders' equity accounts of CitNat and
Security's will be consolidated on Security's balance sheet. Income and other
financial statements of Security issued after consummation of the Merger will be
restated retroactively to reflect the consolidated operations of Security and
CitNat as if the Merger had taken place prior to the periods covered by such
financial statements.

         For the Merger to qualify as a pooling of interests for accounting
purposes, substantially all (90% or more) of the outstanding CitNat Common Stock
must be exchanged for Security Common Stock. All parties have agreed not to take
any action which would disqualify the Merger from pooling of interests treatment
by Security.

EXPENSES

         The Agreement provides that whether or not the Merger is consummated,
all costs and expenses incurred in connection with the Agreement and the
transactions contemplated therein shall be paid by the party incurring such
expense.

RESALE OF SECURITY COMMON STOCK

         The shares of Security Common Stock to be issued in the Merger to
holders of CitNat Common Stock have been registered under the Securities Act and
may be freely traded by holders of CitNat Common Stock who, at the Effective
Time, are not "affiliates" of CitNat (and who are not affiliates of Security at
the time of the proposed resale). Directors, executive officers, and 10%
stockholders of CitNat are generally deemed to be affiliates under the
Securities Act. Pursuant to the Agreement, Security must have received from each
affiliate of CitNat a written undertaking to the effect that (a) he or she will
not sell or dispose of Security Common Stock acquired in the Merger other than
in accordance with the Securities Act, except under (i) a separate registration
statement for distribution 

                                       32
<PAGE>   37
(which Security has not agreed to provide), or (ii) Rule 145 promulgated
thereunder by the SEC, or (iii) some other exemption from registration; and (b)
he or she will not otherwise dispose of the Security Common Stock or otherwise
reduce his or her market risk relative to the Security Common Stock within 30
days prior to the Effective Time of the Merger or prior to the publication by
Security of an earnings statement covering at least 30 days of combined
operations after the Effective Time.

DISSENTERS' RIGHTS

         Under the provisions of Ohio Revised Code, Section 1701.85, any
shareholder of CitNat who does not vote in favor of the Agreement is entitled to
receive the fair cash value of his shares, upon perfecting his right of
appraisal. Not later than ten (10) days after the date upon which the
shareholders voted upon the Merger, any shareholder seeking to perfect his
appraisal right must make a written demand upon CitNat for the fair cash value
of those shares so held by him. A negative vote alone is not sufficient to
perfect rights as a dissenter. No notice of the results of the meeting will be
given to shareholders. If CitNat and the shareholder have not come to an
agreement within three (3) months of the shareholder's written demand, the
shareholder or CitNat may file a petition in court for a formal judicial
appraisal. Failure to follow the procedures enumerated in the Ohio Revised Code,
Section 1701.85, Qualifications of and Procedures for Dissenting Shareholders,
which is Appendix C of this Proxy Statement (the Dissenters Statute), will waive
the shareholder's right of appraisal.

         THE FOREGOING SUMMARY OF DISSENTERS' STATUTE DOES NOT PURPORT TO BE
COMPLETE AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO DISSENTERS' STATUTE
AND THE OTHER PROVISIONS OF THE OHIO LAW. THE FAILURE OF A STOCKHOLDER OF CITNAT
TO FOLLOW THE PROCEDURES SET FORTH IN DISSENTERS' STATUTE WILL TERMINATE SUCH
STOCKHOLDER'S APPRAISAL RIGHTS. AS A CONSEQUENCE, EACH STOCKHOLDER OF CITNAT WHO
DESIRES TO EXERCISE SUCH RIGHTS SHOULD REVIEW DISSENTERS' STATUTE AND FOLLOW ITS
PROVISIONS. THE COMPLETE TEXT OF THE RELEVANT PROVISIONS OF DISSENTERS' STATUTE
IS ANNEXED TO THIS PROXY STATEMENT AS APPENDIX C.

                            PRO FORMA FINANCIAL DATA

         The following unaudited Pro Forma Combined Condensed Balance Sheets as
of December 31, 1995 and March 31, 1996, and the Pro Forma Combined Condensed
Statements of Income for each of the three-year periods ended December 31, 1995,
and the three months ended March 31, 1996 and 1995, gives effect to the Merger
based on the historical consolidated financial statements of Security and CitNat
under the assumptions and adjustments set forth in the accompanying notes to the
pro forma financial statements.

         The Pro Forma Condensed Balance Sheet assumes the Merger was
consummated on the dates indicated, and the Pro Forma Condensed Statements of
Income assume that the Merger was consummated on January 1 of each period
presented. The pro forma statements may not be indicative of the results that
actually would have occurred if the Merger had been in effect on the dates
indicated or which may be obtained in the future. The pro forma financial
statements should be read in conjunction with Security's historical financial
statements and the related notes thereto incorporated by reference herein and
CitNat's historical financial statements and the related notes thereto included
elsewhere in this Proxy Statement-Prospectus. Additionally, the Pro Forma
financial statements prepared by Security reflect the effect of Security's
acquisition of Third for the most recent period shown. The Third Merger will be
accounted for as a purchase. See "INFORMATION ABOUT Security-Pending
Acquisitions."

          NOTES TO PRO FORMA CONDENSED FINANCIAL STATEMENTS (UNAUDITED)

On April 22, 1996, Third entered into an Agreement and Plan of Merger with the
Company. Under the terms of the Merger Agreement, Security has agreed to pay
Merger Consideration of $33.23 per share or $40.05 million, subject to
adjustment. All outstanding shares of Third Common Stock will be surrendered in
consummation of the Merger.

The transaction will be accounted for by the purchase method of accounting.
Accordingly, book values of Third will be adjusted to estimated fair values at
the date the transaction is consummated. For purposes of preliminary valuation
and the pro forma financial statements, the book value of Third's assets and
liabilities are estimated to approximate fair market value. Final purchase
accounting adjustments will be made on the basis of facts and circumstances as
of the date of the consummation of the proposed transaction and therefore may
differ from those reflected herein.

The adjustments in the pro forma condensed financial statements assume the
following:

(a)      The planned special dividend from Subsidiary Bank of $10,050,000.
         Security proposes to cause its Subsidiary Bank to declare a special
         cash dividend of $10,050,000 in the third quarter of 1996.

(b)      The planned borrowing of $30,000,000 by Security.

(c)      Estimated purchase accounting adjustments and the payment of the cost
         of acquisition as follows:

               DESCRIPTION AND COMPARISON OF SECURITY COMMON STOCK
                             AND CITNAT COMMON STOCK


GENERAL

         Security is an Ohio corporation governed by and subject to the Ohio
General Corporation Law ("OGCL"). CitNat is an Ohio corporation organized under
and governed by the provisions of the OGCL. If the proposed Merger is
consummated, stockholders of CitNat who receive Security Common Stock will
become stockholders of Security and, as such, their rights as stockholders will
be governed by the OGCL and by Security's Articles, Code of Regulations and
other corporate documents. The rights of holders of shares of CitNat Common
Stock differ in certain respects from the rights of holders of Security Common
Stock. A summary of the material differences between the respective rights of
CitNat from that of Security stockholders is set forth below.

         As of the date of the Agreement Security was authorized to issue
11,000,000 shares of $3.215 par value common stock ("Security Common Stock"). As
of the date of the Agreement, Security had 5,106,384 shares of Security Common
Stock issued and outstanding, which left 5,893,616 shares available for future
issuance. Pursuant to the terms of the Merger Security will issue an aggregate
of 908,072 shares of Security Common Stock to stockholders and option holders of
CitNat.

         The authorized Common Stock of CitNat consists of 720,000 shares of
Common Stock, $5 par value per share, of which 390,119 are issued and
outstanding as of the Record Date.

         Security Common Stock is not traded on any exchange. Certain
broker/dealers make a market in Security Common Stock and handle purchase and
sale transactions. Trading volume in Security Common Stock for the twelve months
ended December 31, 1995, was _______ shares.

         CitNat Common Stock is not traded on any exchange nor in the
over-the-counter market. Management is unaware of any trades in CitNat Common
Stock for the twelve month period ended December 31, 1995.

         While there are a substantial number of similarities between the
Security Common Stock and the CitNat Common Stock, the rights of stockholders of
CitNat will be different after the Effective Date of the Merger. Stockholders
will be affected by differences in the Articles of Incorporation and Code of
Regulations of Security and CitNat. Listed below are the more important
attributes of the Security Common Stock and the differences, if any, from the
CitNat Common Stock.

DIVIDENDS

         Holders of Security Common Stock are entitled to dividends out of funds
legally available therefor, as governed by the OGCL, and if declared by the
Board of Directors. The amount and timing of dividends on Security Common Stock
is subject to the earnings of its subsidiaries and the amounts available for
payment of dividends by such subsidiaries under federal banking laws and
regulations. Generally, dividends from Security's banking subsidiaries are
restricted to net profits of the current year plus the preceding two years less
dividends paid.

PREEMPTIVE RIGHTS

         Pursuant to the OGCL, stockholders of Security have the preemptive
right to subscribe to additional shares of common stock when issued by Security.
Stockholders of CitNat currently do not have preemptive rights pursuant to the
CitNat's Articles of Incorporation. Preemptive rights permit a stockholder to
purchase their pro rata share of any offering by the company, subject to certain
exceptions and limitations as provided by law.

VOTING

         On all matters to properly come before stockholders, each share of
stock of Security and CitNat entitles the holder thereof to one vote, except,
with respect to the right to vote cumulatively in the election of Directors, and
for 


                                       43
<PAGE>   48
the effect of certain "supermajority vote" requirements regarding business
combinations contained in the Articles of Incorporation of Security and CitNat
(see "Cumulative Voting" and "Antitakeover Provisions"). The affirmative vote of
the holders of a majority of the outstanding Security Common Stock is required
to amend the Articles of Incorporation of Security and CitNat, except the
amendment of the provision contained in each company's Articles of Incorporation
requiring a supermajority vote in certain business combination transactions,
which amendment requires, in certain circumstances, the affirmative vote of the
holders of eighty percent (80%) of the Security Common Stock.

CUMULATIVE VOTING

         Stockholders of CitNat have the right to vote cumulatively in the
election of Directors. Stockholders of Security do not have the right to vote
cumulatively in the election of directors pursuant to Security's Articles of
Incorporation. In cumulative voting, a stockholder may cumulate a number of
votes equal to the number of directors to be elected times the number of shares
held by the stockholder and cast all of such votes for one nominee for director,
or allocate such votes among the nominees as the stockholder sees fit.
Cumulative voting rights afford stockholders controlling a minority stock
position the opportunity to have representation on the Board of Directors.

LIQUIDATION

         Holders of Security and CitNat stock are entitled to a pro rata
distribution of the corporation's assets upon liquidation.

LIABILITY OF DIRECTORS; INDEMNIFICATION

         Under their respective Articles of Incorporation Security and CitNat
may indemnify present or past directors, officers, employees or agents to the
full extent permitted by law.

         The Articles of Incorporation of Security and CitNat both provide as
follows:

         The Corporation shall 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 Ohio Revised Code. Additionally,
         and subject to the limitations set forth below, the Corporation shall
         indemnify its present and past Directors for personal liability for
         monetary damages resulting from breach of their fiduciary duty as
         Directors. Notwithstanding the above, no indemnification for personal
         liability shall be provided for: (i) any breach of the Directors' duty
         of loyalty to the Corporation or its shareholders; (ii) acts or
         omissions not in good faith or which involve intentional misconduct or
         a knowing violation of law; and (iii) any transaction from which the
         Director derived an improper personal benefit.

ANTITAKEOVER PROVISIONS

Ohio Law applicable to Security and CitNat

         Both CitNat and Security are Ohio-chartered corporations and are
"issuing public corporations" under the laws of Ohio, and subject to the
provisions of the Ohio Control Share Acquisition Statute (ORC Section 1701.831)
and the Merger Moratorium Act (ORC Section 1704). Pursuant to the Ohio Control
Share Acquisition Statute, the purchase of certain levels of voting power of
acompany (one-fifth or more, one-third or more, or a majority) can be made only
with the prior authorization of at least a majority of the total voting power of
such company and a separate prior authorization of the holders of at least a
majority of the voting power held by shareholders other than the proposed
purchaser, officers of the company and Directors of the company who are also
employees. This law has the potential effect of deterring certain potential
acquisitions of the company which might be beneficial to shareholders. The
Merger Moratorium Act, enacted in 1990, prohibits certain Ohio corporations from
engaging in specified types of transactions with an "interested shareholder" for
a period of three years after the shareholder becomes an "interested
shareholder" unless the shareholder receives the approval of the corporation's
board of directors prior to 


                                       44
<PAGE>   49
the acquisition of shares or the consummation of the specified type of
transaction. The anticipated effect of the Merger Moratorium Act is to encourage
a potential acquiror to negotiate with a target corporation's board of directors
prior to obtaining a 10 percent or greater block of shares in the corporation.

Security's and CitNat's Articles of Incorporation

         Security's and CitNat's Articles of Incorporation contain two
provisions which can be characterized as antitakeover in nature. These
provisions are identical for each company and are summarized below:

                   Supermajority Vote and Fair Price Provision

         Security and CitNat have a provision in their respective Articles of
Incorporation which provide that in certain business combination transactions,
which are not approved by the incumbent board of directors, a supervote is
required by shareholders in order to approve such a business combination. In the
case of Security the vote of shareholders required under such circumstances is
80% and in the case of CitNat the vote required is 80%. In addition the Articles
of Incorporation of each of Security and CitNat contain a "fair price" provision
which requires an acquiror to pay the same level of consideration for all shares
of the company acquired during the preceding two years. The supermajority and
fair price provisions do not apply to transactions which are approved by the
incumbent board of directors of the company nor to a transaction approved by a
vote of at least 66 2/3% of the shares excluding those owned by the acquiror.

                           Classified Board Provision

         Security and CitNat currently have in operation, a classified election
system for electing their Board of Directors. Directors are elected to a
designated class and shall serve until the expiration of the term for which they
are elected, and until their successors have been duly elected and qualified.
Each of Security and CitNat have three (3) classes and each director is elected
to a three (3) year term such that one-third of the Board is elected each year.

                                Authorized Shares

         The availability of authorized and unissued shares for future issuance
by Security may be deemed to have an antitakeover effect. As of the date of the
Agreement, Security had 5,106,384 authorized shares available for future
issuance. The authorized and unissued shares are available for issuance, subject
to stockholders' preemptive rights as provided by Ohio law, and thereby could be
issued into "friendly hands" to dilute the ownership of an individual or
corporation that has acquired shares of Security and intends to conduct an
acquisition of Security that is deemed to be undesirable by the Board of
Directors of Security.

         These provisions are not the result of management's knowledge of any
effort to obtain control of Security by any means. Security's Articles of
Incorporation and Code of Regulations currently contain no other provisions that
were intended to be or could fairly be considered as antitakeover in nature or
effect. Further, the Board of Directors has no intention to amend the Articles
of Incorporation or Code of Regulations to add any additional antitakeover
provisions.

                           INFORMATION ABOUT SECURITY


GENERAL

         Security, through its affiliate, Security Bank, conducts the business
of a commercial banking organization. At March 31, 1996, Security and its
subsidiaries had consolidated total assets of approximately $542 million,
consolidated total deposits of approximately $432 million and consolidated total
equity of approximately $74 million.

         Security, through its banking affiliate, offers a broad range of
banking services to the commercial, industrial and consumer market segments
which it serves. Services include commercial, real estate and personal 


                                       45
<PAGE>   50
loans; checking, savings and time deposits and other customer services such as
safe deposit facilities. Security does not have any foreign operations, assets
or investments.

         Security Bank is a national banking association. Security Bank is
regulated by the Office of the Comptroller of the Currency ("OCC") and its
deposits are insured by the Federal Deposit Insurance Corporation to the extent
permitted by law and, as a subsidiary of Security, is regulated by the Federal
Reserve Board.

         THIS PROXY STATEMENT-PROSPECTUS, AS MAILED TO STOCKHOLDERS OF CITNAT IS
ACCOMPANIED BY SECURITY'S ANNUAL REPORT TO STOCKHOLDERS FOR THE YEAR ENDED
DECEMBER 31, 1995 (THE "SECURITY 1995 ANNUAL REPORT"). ADDITIONAL INFORMATION
CONCERNING SECURITY IS CONTAINED IN DOCUMENTS INCORPORATED IN THIS PROXY
STATEMENT BY REFERENCE. THESE DOCUMENTS, INCLUDING THE SECURITY 1995 ANNUAL
REPORT AND SECURITY'S FIRST QUARTER REPORT FORM 10Q, ARE AVAILABLE WITHOUT
CHARGE UPON WRITTEN REQUEST TO J. WILLIAM STAPLETON, 40 S. LIMESTONE STREET,
SPRINGFIELD, OHIO 45502. IN ORDER TO ASSURE TIMELY DELIVERY OF THESE DOCUMENTS,
ANY REQUEST SHOULD BE MADE BY ______________________, 1996.

COMPETITION

         The commercial banking and trust business in the market areas served by
Security Bank is very competitive. Security and Security Bank are all in
competition with commercial banks located in their own service areas. Some
competitors of Security and Security Bank are substantially larger than Security
Bank. In addition to local bank competition, Security Bank competes with larger
commercial banks located in metropolitan areas, savings banks, savings and loan
associations, credit unions, finance companies and other financial institutions
for loans and deposits.

CERTAIN REGULATORY CONSIDERATIONS

         The following is a summary of certain statutes and regulations
affecting Security and its subsidiaries. This summary is qualified in its
entirety by such statutes and regulations.

Security

         Security is a registered bank holding company under the Bank Holding
Company Act as amended, ("BHC Act") and as such is subject to regulation by the
Federal Reserve Board. A bank holding company is required to file with the
Federal Reserve Board quarterly reports and other information regarding its
business operations and those of its subsidiaries. A bank holding company and
its subsidiary banks are also subject to examination by the Federal Reserve
Board.

         The BHC Act requires every bank holding company to obtain the prior
approval of the Federal Reserve Board before acquiring substantially all the
assets of any bank or bank holding company or ownership or control of any voting
shares of any bank or bank holding company, if, after such acquisition, it would
own or control, directly or indirectly, more than five percent (5%) of the
voting shares of such bank or bank holding company. Bank holding companies are
also prohibited from acquiring shares of any bank located outside the state in
which the operations of the bank holding company's banking subsidiaries are
principally conducted unless such an acquisition is specifically authorized by a
statute of the state in which the bank whose shares are to be acquired is
located. However, the BHC Act does not place territorial restrictions on the
activities of nonbank subsidiaries of a bank holding company.

         In approving acquisitions by bank holding companies of companies
engaged in banking-related activities, the Federal Reserve Board considers
whether the performance of any such activity by a subsidiary of the holding
company reasonably can be expected to produce benefits to the public, such as
greater convenience, increased competition, or gains in efficiency, which
outweigh possible adverse effects, such as over concentration of resources,
decrease of competition, conflicts of interest, or unsound banking practices.



                                       46
<PAGE>   51
         Bank holding companies are restricted in, and subject to, limitations
regarding transactions with subsidiaries and other affiliates.

         In addition, bank holding companies and their subsidiaries are
prohibited from engaging in certain "tie in" arrangements in connection with any
extensions of credit, leases, sales of property, or furnishing of services.

Security Subsidiaries

         Security operates a single national bank, namely, Security Bank. As a
national bank Security Bank is supervised and regulated by the OCC, and subject
to laws and regulations applicable to national banks.

Capital

         The Federal Reserve Board, OCC, and FDIC require banks and holding
companies to maintain minimum capital ratios.

         The Federal Reserve Board has adopted final "risk-adjusted" capital
guidelines for bank holding companies. The new guidelines became fully
implemented as of December 31, 1992. The OCC and FDIC have adopted substantially
similar risk-based capital guidelines. These ratios involve a mathematical
process of assigning various risk weights to different classes of assets, then
evaluating the sum of the risk-weighted balance sheet structure against
Security's capital base. The rules set the minimum guidelines for the ratio of
capital to risk-weighted assets (including certain off-balance sheet activities,
such as standby letters of credit) at 8%. At least half of the total capital is
to be composed of common equity, retained earnings, and a limited amount of
perpetual preferred stock less certain goodwill items ("Tier 1 Capital"). The
remainder may consist of a limited amount of subordinated debt, other preferred
stock, or a limited amount of loan loss reserves. At March 31, 1996 Security's
consolidated risk-adjusted Tier 1 Capital and total capital, as defined by the
regulatory agencies based on the fully phased in 1992 guidelines, were 21.54%
and 22.65% of risk-weighted assets, respectively, well above the 4% and 8%
minimum standards mandated by the regulatory agencies.

         In addition, the federal banking regulatory agencies have adopted
leverage capital guidelines for banks and bank holding companies. Under these
guidelines, banks and bank holding companies must maintain a minimum ratio of
three percent (3%) Tier 1 Capital (as defined for purposes of the year-end 1992
risk-based capital guidelines) to total assets. The Federal Reserve Board has
indicated, however, that banking organizations that are experiencing or
anticipating significant growth, are expected to maintain capital ratios well in
excess of the minimum levels. As of March 31, 1996, Security's core leverage
ratio was 13.7%, well above the regulatory minimum.

         Regulatory authorities may increase such minimum requirements for all
banks and bank holding companies or for specified banks or bank holding
companies. Increases in the minimum required ratios could adversely affect
Security and Security Banks, including their ability to pay dividends.

Additional Regulation

         Security Bank is also subject to federal regulation as to such matters
as required reserves, limitation as to the nature and amount of its loans and
investments, regulatory approval of any merger or consolidation, issuance or
retirement of their own securities, limitations upon the payment of dividends
and other aspects of banking operations. In addition, the activities and
operations of Security Bank are subject to a number of additional detailed,
complex and sometimes overlapping laws and regulations. These include state
usury and consumer credit laws, state laws relating to fiduciaries, the Federal
Truth-in-Lending Act and Regulation Z, the Federal Equal Credit Opportunity Act
and Regulation B, the Fair Credit Reporting Act, the Truth in Savings Act, the
Community Reinvestment Act, anti-redlining legislation and antitrust laws.


                                       47
<PAGE>   52
Dividend Regulation

         The ability of Security to obtain funds for the payment of dividends
and for other cash requirements is largely dependent on the amount of dividends
which may be declared by Security Bank. Generally, Security Bank may not declare
a dividend, without the approval, if the total of dividends declared in a
calendar year exceeds the total of its net profits for that year combined with
its retained profits of the preceding two years.

Government Policies and Legislation

         The policies of regulatory authorities, including the OCC, Federal
Reserve Board, FDIC and the Depository Institutions Deregulation Committee, have
had a significant effect on the operating results of commercial banks in the
past and are expected to do so in the future. An important function of the
Federal Reserve System is to regulate aggregate national credit and money supply
through such means as open market dealings in securities, establishment of the
discount rate on member bank borrowings, and changes in reserve requirements
against member bank deposits. Policies of these agencies may be influenced by
many factors, including inflation, unemployment, short-term and long-term
changes in the international trade balance and fiscal policies of the United
States government.

         The United States Congress has periodically considered and adopted
legislation which has resulted in further deregulation of both banks and other
financial institutions, including mutual funds, securities brokerage firms and
investment banking firms. No assurance can be given as to whether any additional
legislation will be adopted or as to the effect such legislation would have on
the business of Security or Security Bank.

         In addition to the relaxation or elimination of geographic restrictions
on banks and bank holding companies, a number of regulatory and legislative
initiatives have the potential for eliminating many of the product line barriers
presently separating the services offered by commercial banks from those offered
by nonbanking institutions. For example, Congress recently has considered
legislation which would expand the scope of permissible business activities for
bank holding companies (and in some cases banks) to include securities
underwriting, insurance services and various real estate related activities as
well as allowing interstate branching.

Deposit Insurance

         The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") was enacted in 1991. Among other things, FDICIA, requires federal
bank regulatory authorities to take "prompt corrective action" with respect to
banks that do not meet minimum capital requirements. For these purposes, FDICIA
establishes five capital tiers: well capitalized, adequately capitalized,
undercapitalized, significantly undercapitalized, and critically
undercapitalized.

         The Federal Reserve Board, the OCC and the FDIC have adopted
regulations to implement the prompt corrective action provisions of FDICIA,
effective December 19, 1992. Among other things, the regulations define the
relevant capital measures for the five capital categories. An institution is
deemed to be "well capitalized" if it has a total risk-based capital ratio
(total capital to risk-weighted assets) of 10% or greater, a Tier 1 risk-based
capital ratio (Tier 1 Capital to risk-weighted assets) of 6% or greater, and a
Tier 1 leverage capital ratio (Tier 1 Capital to total assets) of 5% or greater,
and is not subject to a regulatory order, agreement or directive to meet and
maintain a specific capital level for any capital measure. An institution is
deemed to be "adequately capitalized" if it has a total risk-based capital ratio
of 8% or greater, a Tier 1 risk-based capital of 4% or greater, and (generally)
a Tier 1 leverage capital ratio of 4% or greater, and the institution does not
meet the definition of a "well capitalized" institution. An institution is
deemed to be "critically undercapitalized" if it has a ratio of tangible equity
(as defined in the regulations) to total assets that is equal to or less than
2%. "Undercapitalized" banks are subject to growth limitations and are required
to submit a capital restoration plan. If an "undercapitalized" bank fails to
submit an acceptable plan, it is treated as if it is significantly
undercapitalized. "Significantly undercapitalized" banks may be subject to a
number of requirements and restrictions, including orders to sell sufficient
voting stock to become adequately capitalized, requirements to reduce total
assets, and cessation of receipt of deposits from correspondent 


                                       48
<PAGE>   53
banks. "Critically undercapitalized" institutions may not, beginning 60 days
after becoming "critically undercapitalized," make any payment of principal or
interest on their subordinated debt.

         Security and Security Bank currently exceed the regulatory definition
of a "well capitalized" financial institution.

         On June 17, 1993, the FDIC issued regulations establishing a permanent
risk-based assessment system. These regulations took effect October 1, 1993, and
were first used to determine assessments for the assessment period commencing
January 1, 1994. During 1994, Security Bank was assessed at the rate of .23% of
deposits under the transitional assessment system. During 1995 the FDIC reduced
the assessment payable on deposits insured by the Bank Insurance Fund ("BIF") to
$2,000 per BIF insured institution. The FDIC has maintained the rate payable on
deposits insured by the Saving Association Insurance Fund ("SAIF") at .23%. This
created a significant disparity between the deposit insurance premiums paid by
BIF and SAIF members. The deposits of Third are insured by the SAIF.

         The United States Congress and the federal banking agencies are
actively considering several options to address this disparity, including a
one-time assessment of up to 0.90% of insured deposits to be imposed on all SAIF
members. While it is uncertain whether this or any proposal for addressing the
insurance premium disparity will be adopted, assuming the Third Merger is
consummated and based upon the deposits of Third at March 31, 1995 (as
proposed), the proposed one-time assessment would be approximately $645,000
after taxes.

         Among other various proposals currently being considered by the FDIC
and Congress, in connection with the recent premium disparity between BIF and
SAIF insured depository institutions, is is a requirement that savings
institutions convert to commercial banks. Under current federal income tax laws,
a savings institution converting to commercial bank must "recapture" into
taxable income the amount of its tax bad debt reserve that would not have been
allowed if the savings institution had operated as a commercial bank. The tax
associated with the recapture of all or part of its tax bad debt reserve would
immediately reduce the capital of the savings institution, even though such tax
would actually be paid out over the succeeding years. It is impossible to
predict whether the foregoing proposal will be adopted in its current form or,
if adopted, whether such proposed might be amended to remove some or all of the
adverse financial and tax effect from the recapture.

         The FDIC may terminate the deposit insurance of any insured depository
institution if the FDIC determines, after a hearing, that the institution has
engaged or is engaging in unsafe or unsound practices, is in an unsafe or
unsound condition to continue operations or has violated any applicable law,
regulation, order, or any condition imposed in writing by, or written agreement
with, the FDIC. The FDIC may also suspend deposit insurance temporarily during
the hearing process for a permanent termination of insurance if the institution
has no tangible capital. Management of Security is not aware of any activity or
condition that could result in termination of the deposit insurance of the
Security Bank.

Recent Legislation

         On September 29, 1994, the Reigle/Neal Interstate Banking and Branching
Efficiency Act of 1994 (the "Interstate Act") was signed into law. This
Interstate Act effectively permits nationwide banking. The Interstate Act
provides that one year after enactment, adequately capitalized and adequately
managed bank holding companies may acquire banks in any state, even in those
jurisdictions that currently bar acquisitions by out-of-state institutions,
subject to deposit concentration limits. The deposit concentration limits
provide that regulatory approval by the Federal Reserve Board may not be granted
for a proposed interstate acquisition if after the acquisition, the acquiror on
a consolidated basis would control more than 10% of the total deposits
nationwide or would control more than 30% of deposits in the state where the
acquiring institution is located. The deposit concentration state limit does not
apply for initial acquisitions in a state and in every case, may be waived by
the state regulatory authority. Interstate acquisitions are subject to
compliance with the Community Reinvestment Act ("CRA"). States are permitted to
impose age requirements not to exceed five years on target banks for interstate
acquisitions. States are not allowed to opt-out of interstate banking.


                                       49
<PAGE>   54
         Branching between states may be accomplished either by merging separate
banks located in different states into one legal entity, or by establishing de
novo branches in another state. Consolidation of banks is not permitted until
June 1, 1997, provided that the state has not passed legislation "opting-out" of
interstate branching. If a state opts-out prior to June 1, 1997, then banks
located in that state may not participate in interstate branching. A state may
opt-in to interstate branching by bank consolidation or by de novo branching by
passing appropriate legislation earlier than June 1, 1997. Interstate branching
is also subject to a 30% statewide deposit concentration limit on a consolidated
basis, and a 10% nationwide deposit concentration limit. The laws of the host
state regarding community reinvestment, fair lending, consumer protection
(including usury limits) and establishment of branches shall apply to the
interstate branches.

         De novo branching by an out-of-state bank is not permitted unless the
host state expressly permits de novo branching by banks from out-of-state. The
establishment of an initial de novo branch in a state is subject to the same
conditions as apply to initial acquisition of a bank in the host state other
than the deposit concentration limits.

         Effective one year after enactment, the Interstate Act permits bank
subsidiaries of a bank holding company to act as agents for affiliated
depository institutions in receiving deposits, renewing time deposits, closing
loans, servicing loans and receiving payments on loans and other obligations. A
bank acting as agent for an affiliate shall not be considered a branch of the
affiliate. Any agency relationship between affiliates must be on terms that are
consistent with safe and sound banking practices. The authority for an agency
relationship for receiving deposits includes the taking of deposits for an
existing account but is not meant to include the opening or origination of new
deposit accounts. Subject to certain conditions, insured savings associations
which were affiliated with banks as of June 1, 1994, may act as agents for such
banks. An affiliate bank or savings association may not conduct any activity as
an agent which such institution is prohibited from conducting as principal. If
an interstate bank decides to close a branch located in a low or moderate-income
area, it must comply with additional branch closing notice requirements. The
appropriate regulatory agency is authorized to consult with community
organizations to explore options to maintain banking services in the affected
community where the branch is to be closed.

         To ensure that interstate branching does not result in taking deposits
without regard to a community's credit needs, the regulatory agencies are
directed to implement regulations prohibiting interstate branches from being
used as "deposit production offices." The regulations to implement its
provisions are due by June 1, 1997. The regulations must include a provision to
the effect that if loans made by an interstate branch are less than fifty
percent of the average of all depository institutions in the state, then the
regulator must review the loan portfolio of the branch. If the regulator
determines that the branch is not meeting the credit needs of the community, it
has the authority to close the branch and to prohibit the bank from opening new
branches in that state.

         When the interstate banking provisions become effective in one year,
Security will have enhanced opportunities to acquire banks in any state subject
to approval by the appropriate federal and state regulatory agencies. When the
interstate branching provisions become effective in June 1997, Security will
have the opportunity to consolidate affiliate banks located in different states
to create one legal entity with branches in more than one state should
management decide to do so, or to establish branches in different states,
subject to any state opt-out provisions. The agency authority permitting
Security affiliate banks to act as agents for each other in accepting deposits
or servicing loans should make it more convenient for customers of one Security
bank to transact their banking business at a Security affiliate in another
state provided that operations are in place to facilitate these out of state
transactions. Security does not presently own nor does it have any present plans
or commitments to own any out of state affiliates.

         On November 18, 1993, the FDIC, together with the Federal Reserve, the
OCC and the Office of Thrift Supervision (the "OTS"), published for comment
proposed rules implementing the FDICIA requirement that the federal banking
agencies establish operational and managerial standards to promote the safety
and soundness of federally insured depository institutions. The proposal would
establish standards for internal controls, information systems, internal audit
systems, loan documentation, credit underwriting, interest rate exposure, asset
growth, and compensation, fees and benefits. In general, the standards set forth
in the proposal consist of the goals to be achieved in each area, and each
institution would be responsible for establishing its own procedures to achieve
those goals. Additionally, the proposal would establish a maximum permissible
ratio of classified assets to capital and a 


                                       50
<PAGE>   55
minimum required earnings ratio. If an institution failed to comply with any of
the standards set forth in the proposal, the institution would be required to
submit to its primary federal regulator a plan for achieving and maintaining
compliance. Failure to submit an acceptable plan, or failure to comply with a
plan that has been accepted by the appropriate regulator, would constitute
grounds for further enforcement action. Based upon a review of the proposal,
management of the Bank believes that the proposal, if adopted in substantially
the form proposed, will not have a material adverse effect on the Bank

         On May 17, 1995, the FDIC, together with the Federal Reserve, the OCC
and the OTS issued new regulations under the Community Reinvestment Act ("CRA").
Under the proposal, an institution's performance in meeting the credit needs of
its entire community, including low and moderate income areas, as required by
the CRA, would generally be evaluated under three tests: the "lending test,"
which would consider the extent to which the institution makes loans in the low
and moderate income areas of its market; the "service test," which would
consider the extent to which the institution makes branches accessible to low
and moderate income areas of its market and provides other services that promote
credit availability; and the "investment test," which would consider the extent
to which the institution invests in community and economic development
activities.

Proposed Legislation

         In addition to the above, there have been proposed a number of
legislative and regulatory proposals designed to strengthen the federal deposit
insurance system and to improve the overall financial stability of the U.S.
banking system. It is impossible to predict whether or in what form these
proposals may be adopted in the future, and if adopted, what their effect would
be on Security.

PRINCIPAL HOLDER OF SECURITY COMMON STOCK

         The following table sets forth information concerning the number of

uncertainty, management of the Company does not anticipate that any currently
pending or threatened litigation has the potential to materially affect the
financial condition or results of operations of Security.

As of the date of this Proxy-Statement Prospectus management is aware of no
pending litigation against Security or any of its subsidiaries.

PENDING ACQUISITION

will exchange all of the outstanding shares of Third Common Stock on the

CITNAT'S FINANCIAL STATEMENTS AND MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

         This discussion is intended to focus on certain financial information
regarding CitNat Bancorp, Inc. ("Company") and its wholly owned subsidiary, The
Citizens National Bank of Urbana ("Bank"). This discussion should be read in
conjunction with the consolidated financial statements and accompanying notes
approving elsewhere herein.

         The Company 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. The Company is also
not aware of any current recommendations by its regulatory authorities that
would have such impact if implemented.

RESULTS OF OPERATIONS - DECEMBER 31, 1995, 1994 AND 1993

         Net income in 1995 of $1,625,000 represents a 9 percent increase over
the net income of $1,472,000 in 1994 which in turn increased by 12 percent over
the net income of $1,300,000 reported in 1993. The primary factors which have
influenced these positive operating results are discussed below.

         Net interest income is the primary source of earnings for the Company
and consists of the difference between the interest income earned on loans and
investments and the interest expense incurred on deposits and short-term
borrowings. Changes in the mix and volume of interest-earnings assets and
interest-bearing liabilities and their related yields have a major impact on
earnings. Management attempts to manage the repricing of assets and liabilities
so as to achieve a stable level of net interest income and minimize the effect
of significant changes in the market level of interest rates. This is
accomplished through the pricing and promotion of loan and deposit products.

         Net interest income computed on a fully taxable equivalent basis
increased by $276,000 in 1995 over 1994. The source of this increase can be
attributed to an increase in the average volume of earnings assets, particularly
commercial and real estate loans. A portion of the increase in loans represents
a shift of funds from lower yielding U.S. Government and Agency securities which
also contributed to the increased net interest income.

         Net interest income computed on a fully taxable equivalent basis
increased by $490,000 in 1994 compared to 1993. This increase is due largely to
a change in the mix of earning assets as the proceeds from maturing investment
securities were used to fund new loans. Investment securities declined by
$9,274,000 from December 31, 1993 to 1994, while loans, primarily real estate
and commercial loans, increased by slightly over $11,000,000 during the same
period. Since the average yield earned on the loan portfolio has exceeded the
average yield earned on the investment portfolio by 200 to 300 basis points over
the last several years, this shift in asset mix increased net interest income.

         The provision for loan losses for years ended December 31, 1995, 1994
and 1993 were $150,000, $44,000 and $150,000, respectively. The reduced
provision in 1994 is a result of net recoveries, experienced in that year, of
previously charged-off loans.

         Other operating income includes service charges and fees on loan and
deposit accounts, safe deposit box rental income and other miscellaneous fee
income. This has been a relatively stable source of revenue for the Company with
no significant fluctuations experienced from 1993 through 1995. The Company has
historically held its portfolio of investment securities to maturity so gains or
losses from the sale of securities have not had any significant impact on
earnings. While management has classified the majority of the investment
portfolio as available for sale under the provisions of Statement of Financial
Accounting Standards No. 115, this was done for liquidity purposes and
management has no current plans for significant sales of securities.



                                       55
<PAGE>   60
         Total other operating expenses have also been relatively stable for the
Company over the last three years reflecting an increase of approximately 8.5
percent for 1994 over 1993 and a decline of approximately 1 percent for 1995
compared to 1994. Individual components of other operating expenses which
fluctuated during the period were salaries and employee benefits which increased
by 10.6 percent in 1994 over 1993 and federal deposit insurance expense which
declined by 51.2 percent in 1995. This increase in salaries and benefits was a
result of additional staff from the Farmers National Bank of Plain City,
purchased in May of 1993 being employed for a full year in 1994 and general
merit increases. The reduction in federal deposit insurance expense occurred in
mid-1995 when the FDIC reduced insurance assessments from $.23 per $100 of
deposits to $.04 per $100 of deposits.

         The Company's effective federal income tax rate has been approximately
28 percent for 1995, 1994 and 1993. This is less than the stated corporate tax
rate of 34 percent due to the Company's investment in nontaxable securities of
states and municipal governments.

FINANCIAL CONDITION

         Total assets of the Company increased from $126,731,000 at December 31,
1994 to $140,131,000 at December 31, 1995, an increase of 10.6 percent. This
growth was primarily in the area of cash and cash equivalents which increased
from $6,299,000 at the end of 1994 to $20,300,000 at the end of 1995.
Contributing to this unusual increase in cash and cash equivalents were
unexpected increases in deposits from commercial business customers received at
the end of 1995. A portion of these deposits were subsequently withdrawn and, as
reflected elsewhere herein, total assets of the Company at March 31, 1996 were
$135,031,000.

         Total investment securities declined by $1,900,000 from 1994 to 1995 as
maturities of securities were used to fund increased loan demand.

         The distribution of the investment portfolio consists of U.S. Treasury
Securities representing 25 percent, U.S. Government Agency Securities
representing 47 percent, Corporate bonds and equity securities representing 12
percent and securities of States and Political Subdivisions representing 16
percent. The Company holds no mortgage-backed securities or other types of
derivative securities.

         Effective January 1, 1994, the Company adopted the provisions of
Statement of Financial Accounting Standards No. 115 and accordingly classified
securities as either held to maturity or available for sale. All municipal
securities have been classified as held to maturity because they are purchased
for the benefit of the tax-free yield. These securities are carried at amortized
cost on the Company's balance sheet. All remaining securities are classified as
available for sale and are carried at fair value. While securities classified as
available for sale could be sold to meet liquidity needs, management has
historically not sold significant amounts of securities prior to maturity.

         The Company's loan portfolio consisted of the following loan types at
December 31, 1995 and 1994 (in thousands):

         At December 31, 1995 and 1994, the loan portfolio included
approximately $17,479,000 and $18,288,000 of loans for agricultural purposes. No
other concentrations of loans are known to exist for a single industry or group
of related borrowers which exceeds 10 percent of the loan portfolio. The Company
also has no foreign loans outstanding.

         Using salaried loan officers, the Company originates loans from
customers located principally in Champaign County and portions of surrounding
counties. The Company has not purchased significant participations in loans
originated by others and it has not sold significant participations in loans to
others.

         Nonaccrual, past due and restructured loans at December 31, 1995 and
1994 are summarized below (in thousands). The policy for placing loans on
nonaccrual status is to cease accruing interest on loans when management
believes that the collection of interest is doubtful, or when loans are past due
as to principal and interest ninety days or more, except that in certain
circumstances interest accruals are continued on loans deemed by management to
be fully collectible. In such cases, the loans are individually evaluated to
determine whether to continue income recognition after ninety days beyond the
due dates. When loans are charged off, any accrued interest recorded in the
fiscal year is charged against interest income. The remaining balance is treated
as a loan charge-off.

         The amount of interest income foregone on nonaccrual and restructured
loans is not material for either period. At December 31, 1995 and 1994, the Bank
had other loans totalling approximately $520,000 and $314,000, respectively,
that do not meet criteria for disclosure above, but for which management has
doubt about the ability of the borrowers to comply with loan repayment terms.
Such loans have been considered by management in evaluating the adequacy of the
allowance for loan losses.

         The allowance for loan losses is maintained by management at a level
considered adequate to cover loan losses that are currently anticipated based on
past loss experience, general economic conditions, changes in the mix and size
of the loan portfolio, information about specific borrower situations and other
factors and estimates which are subject to change over time. Management
periodically reviews and grades selected large loans, delinquent and other
problem loans and loans which have been adversely rated by regulatory agencies.
The collectibility of these loans is evaluated by considering the current
financial position and performance of the borrower, the estimated value of
collateral, the Company's collateral position in relationship to other
creditors, guarantees and other sources of repayment. Management forms
judgements which are subjective as to the probability of loss and the amount of
loss on these loans as well as other loans in the aggregate.

         The allowance for loan losses totalled $1,595,000 at December 31, 1995
and $1,555,000 at December 31, 1994, representing 1.95 percent and 1.92 percent
of total loans, respectively.

         Total shareholders' equity increased from $15,306,000 at December 31,
1994 to $17,451,000 at December 31, 1995 for an increase of 14 percent.
Contributing to this increase were earnings of $1,625,000 in 1995 and a change
in the unrealized gain/loss on securities available for sale of $627,000. For
both 1995 and 1994, the Company has paid semiannual stock dividends of 1 percent
to shareholders, in lieu of cash dividends.

         Banking regulations have established minimum capital requirements for
banks and bank holding companies including risk-based capital ratios and
leverage ratios. As of December 31, 1995, risk-based capital regulations require
a minimum total risk-based capital ratio of 8 percent, with half of the capital
composed of core capital. Minimum leverage ratios range from 3 percent to 5
percent of total assets. Conceptually, risk-based capital requirements assess
the riskiness of a financial institution's balance sheet and off-balance sheet
commitments in relation to its capital. Core capital, or Tier 1 capital,
includes common equity, perpetual preferred stock and minority interests that
are held by others in consolidated subsidiaries minus intangible assets.
Supplementary capital, or Tier 2 capital, includes core capital and such items
as mandatory convertible securities, subordinated debt and the allowance for
loans and lease losses, subject to certain limitations. Qualified Tier 2 capital
can equal up to 



                                       58
<PAGE>   63
100 percent of an institution's Tier 1 capital with certain limitations in
meeting the total risk-based capital requirements. During 1994, the regulatory
authorities determined that the adjustment to shareholders' equity resulting
from the adoption of SFAS No. 115 would not be considered in the determination
of regulatory capital.

At December 31, 1995, the Company's total risk-based capital ratio and leverage
ratio were 27.17 percent and 12.40 percent, respectively, thus significantly
exceeding the minimum regulatory requirements. At December 31, 1994, the
respective ratios were 21.24 percent and 12.42 percent.

LIQUIDITY

Liquidity management for the Company centers around the assurance that funds are
available to meet the loan and deposit needs of its customers and the Bank's
other financial commitments.

Cash and noninterest-bearing deposits with banks and federal funds sold totalled
$20,300,000 at December 31, 1995 and $6,299,000 at December 31, 1994. These
assets provide the primary source of liquidity for the Company. In addition, the
Company has designated a substantial portion of its investment portfolio 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, 1995 and 1994, the ratio of
loans to deposits was 68.6 percent and 74.2 percent, respectively, considered an
acceptable level of liquidity by management.


IMPACT OF INFLATION

The financial data included herein has been prepared in accordance with
generally accepted accounting principles which generally do not recognize
changes in the relative value of money due to inflation or deflation.

In management's opinion, changes in interest rates affect the financial
condition of a financial institution to a far greater degree than changes in the
inflation rate. While interest rates are greatly influenced by changes in the
inflation rate, they do not change at the same rate or in the same magnitude as
the inflation ratio. Rather, interest rate volatility is based on changes in
monetary and fiscal policy. A financial institution's ability to be relatively
unaffected by changes in interest rates is a good indicator of its capability to
perform in today's volatile economic environment. The Company seeks to insulate
itself from interest rate volatility by ensuring that rate-sensitive assets and
rate-sensitive liabilities respond to changes in interest rates in a similar
time frame and to a similar degree.


RESULTS OF OPERATIONS - MARCH 31, 1996 AND 1995

Net income for the three months ended March 31, 1996 was $426,000, an increase
of $46,000 or 12.1 percent over the $380,000 recorded for the three months ended
March 31, 1995. The primary cause of this increase was an increase in other
income related to greater fee revenue earned from the sale of credit life and
accident and health insurance policies to loan customers.

As reflected in the accompanying financial statements, the Company's net
interest income was virtually unchanged at $1,555,000 for the first quarter of
1996 compared to $1,552,000 for the first quarter of 1995.

The provision for loan losses was $38,000 for both the first quarter of 1996 and
1995 as the Company continued to experience modest loan charge-offs and the
level of nonperforming loans continued to be low.

Total other operating expenses were $1,186,000 for both the three months ended
March 31, 1996 and 1995. Within this category, an increase in other
miscellaneous expense attributed primarily to advertising and postage was offset
by a reduction in federal deposit insurance expense. The FDIC eliminated deposit
insurance assessments beginning in 1996 for well-capitalized banks as the Bank
Insurance Fund reached its required level of reserves.

FINANCIAL CONDITION - MARCH 31, 1996

         Total assets declined to $135,031,000 at March 31, 1996, compared to
$140,131,000 at December 31, 1995. This decline is consistent with the change in
total deposits which were $114,688,000 at March 31, 1996 compared to
$119,588,000 as of December 31, 1995. As previously indicated, the Company
experienced an unexpected inflow of deposits near the end of 1995. Also,
year-end deposit balances are typically higher than other periods of the year as
agricultural customers build deposit balances from the sale of farm products.

         Cash and cash equivalents declined from $20,300,000 at year-end 1995 to
$11,935,000 at March 31, 1996. This change related to the funding of deposit
withdrawals and an increase in interest-bearing balances with other banks.

         Investment securities available for sale increased from $28,523,000 at
the end of 1995 to $31,507,000 at March 31, 1996. Maturities of U.S. Government
Agencies and Corporate securities were invested in U.S. Treasury securities. As
noted below, loan demand was soft for the first quarter of 1996 and funds
received from net loan repayments contributed to the increase in securities.

         Total loans were $80,285,000 at March 31, 1996 compared to $81,995,000
at December 31, 1995. The composition of the loan portfolio at March 31, 1996,

Most loan categories declined for the quarter with the largest change occurring
in consumer loans which declined by $780,000 or 5 percent. Competition for loans
in the Company's primary lending area has become more intense, particularly
competition for agricultural loans from government-sponsored lenders and
insurance funds. Also, the Company generally does not aggressively pursue
indirect automobile loans which comprise a significant portion of the local
consumer loan market. At March 31, 1996, the loan portfolio included
approximately $16,753,000 of loans for agricultural purposes. Nonaccrual, past
due and restructured loans at March 31, 1996 are summarized below (in

The allowance for loan losses totalled $1,663,000 at March 31, 1996 compared to
$1,595,000 at December 31, 1995 representing 2.07 percent and 1.95 percent of
total loans, respectively. Loans charged-off in the first quarter of 1996
totalled $28,000 while recoveries of previously charged-off loans totalled
$58,000.

Total shareholders' equity increased to $17,704,000 at March 31, 1996 from
$17,451,000 at December 31, 1995. The change results from earnings for the
quarter of $426,000, a decline in the estimated fair value of securities
available for sale, net of tax effect, of $155,000 and treasury stock
repurchases of $18,000. The Company's total risk-based capital and leverage
ratio were 23.50 percent and 13.15 percent at March 31, 1996, continuing to be
well-above the minimum regulatory requirements.

                         REPORT OF INDEPENDENT AUDITORS

Shareholders and Board of Directors
CitNat Bancorp, Inc.
Urbana, Ohio



We have audited the accompanying consolidated balance sheets of CitNat Bancorp,
Inc. as of December 31, 1995 and 1994, and the related consolidated statements
of income, changes in shareholders' equity, and cash flows for the years ended
December 31, 1995, 1994 and 1993. These consolidated financial statements are
the responsibility of management. Our responsibility is to express an opinion on
these consolidated 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 consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of CitNat Bancorp, Inc.
as of December 31, 1995 and 1994, and the results of its operations and cash
flows for the years ended December 31, 1995, 1994 and 1993 in conformity with
generally accepted accounting principles.

As discussed in Note 1 to the financial statements, the Company changed its
method of accounting for impaired loans in 1995 and certain investment
securities in 1994 to comply with new accounting guidance.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed in the
preparation of the accompanying consolidated financial statements.

Basis of Presentation: The consolidated financial statements include the
accounts of CitNat Bancorp, Inc. (Company) and its wholly owned subsidiary, The
Citizens National Bank of Urbana (Bank). All material intercompany transactions
and balances have been eliminated.

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

Statement of Cash Flows: For purposes of reporting cash flows, cash and cash
equivalents include cash, short-term interest-bearing deposits with financial
institutions and federal funds sold. Generally, federal funds are sold for
one-day periods. The Company reports net cash flows for customer loan
transactions, deposits transactions and short-term borrowings. For the years
ended December 31, 1995, 1994 and 1993, the Company paid interest of $3,717,000,
$2,962,000 and $3,360,000 and income taxes of $672,000, $629,000 and $583,000,
respectively.

Investment Securities: Effective January 1, 1994, the Company adopted the
provisions of Statement of Financial Accounting Standards (SFAS) No. 115,
"Accounting for Certain Investments in Debt and Equity Securities". SFAS No. 115
requires corporations to classify debt securities as held to maturity, trading
or available for sale. The effect of adjusting securities available for sale to
fair value, net of applicable income tax effects is reported as a separate
component of shareholders' equity in the balance sheet. The effect of adopting
SFAS No. 115 on January 1, 1994 was to increase shareholders' equity by
$775,000.

Securities classified as held to maturity are those that management has the
positive intent and ability to hold to maturity. Securities classified as
available for sale are those that management intends to sell or that would be
sold for liquidity, investment management, or similar reasons, even if
management does not presently intend such a sale.

Securities held to maturity are stated at cost, adjusted for amortization of
premiums and accretion of discounts. Securities available for sale are carried
at fair value using the specific identification method. Unrealized gains and
losses are recorded as a net amount in a separate component of shareholders'
equity, net of tax effects. Gains or losses on dispositions are based on net
proceeds and the adjusted carrying amount of securities sold, using the specific
identification method.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Interest Income on Loans: Interest income on loans is accrued over the term of
the loans based on the principal balance outstanding. When substantial doubt
exists as to the collectibility of a loan, the interest accrual is discontinued.
Loan origination fees, net of direct loan origination costs, are deferred and
recognized over the life of the loan as a yield adjustment. The net amount
deferred is reported in the Balance Sheet as a reduction of loans.

The carrying values of impaired loans are 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. Other cash payments are
reported as reductions in carrying value, while increases or decreases due to
changes in estimates of future payments and due to the passage of time are
reported as part of the provision for loan losses.

Allowance for Possible Loan Losses: The allowance for possible loan loss, which
is reported as a deduction from loans, is available for loan charge-offs. This
allowance is increased by provisions charged to earnings and is reduced by loan
charge-offs, net of recoveries. The adequacy of the allowance is based on
management's evaluation of several key factors including information about
specific borrower situations, their financial position and collateral values,
current economic conditions, changes in the mix and levels of the various types
of loans, past charge-off experience, and other pertinent information. The
allowance for possible loan losses is based on estimates using currently
available information, and ultimate losses may vary from current estimates due
to changes in circumstances. These estimates are reviewed periodically and, as
adjustments become necessary, they are reported in earnings in the periods in
which they become known. Charge-offs are made against the allowance for possible
loan loss when management concludes that loan amounts are likely to be
uncollectible.

On January 1, 1995, the Company adopted SFAS 114, "Accounting by Creditors for
Impairment of a Loan" and SFAS 118, "Accounting by Creditors for Impairment of a
Loan - Income Recognition and Disclosures." SFAS 114 specifies that allowances
for loan losses on impaired loans should be determined using the present value
of estimated future cash flows of the loan, discounted at the loan's effective
interest rate, or the fair value of the collateral. A loan is impaired when all
principal and interest amounts will not likely be collected according to the
loan contract. The impact of adoption of SFAS 114 and SFAS 118 on the financial
position or results of operations of the Company was not significant.

Premises and Equipment: Premises and equipment are stated at cost less
accumulated depreciation. Premises and equipment are depreciated on the
straight-line and declining-balance methods over the estimated useful lives of
the assets. Maintenance and repairs are expensed and major improvements are
capitalized.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Other Real Estate: Real estate acquired through foreclosure is initially
recorded at the lower of the recorded loan amount or the fair market value of
the asset received. If management later determines that the total capitalized
cost of the property cannot be recovered through sale or use, the loss is
recognized in the current period by a charge to income with a corresponding
writedown of the asset.

Per Share Amounts: The Company declared 1% stock dividends payable to
shareholders of record as of June 20, 1995 and November 21, 1995, and 1% stock
dividends payable to shareholders as of June 21, 1994 and December 1, 1994. The
Company also paid a 5% stock dividend payable to shareholders of record as of
December 31, 1993. Fractional shares were paid in cash. These stock dividends
resulted in the issuance of 3,704, 3,735, 3,609, 3,670 and 17,883 shares of
common stock, respectively. Dividends per share and earnings per share amounts
have been computed as though the additional shares had always been outstanding.

In addition, earnings per share amounts take into consideration the dilutive
effects of the stock option plan adopted by the Board of Directors on April 6,
1994. Earnings per common share and common share equivalent has been computed
assuming the exercise of dilutive stock options, less the treasury shares
assumed to be purchased from the proceeds using the average market price of the
Company's stock for the period options were outstanding. Fully diluted earnings
per common share represents the additional dilution related to the stock options
due to the use of the market price as of the end of the year if it exceeds the
average price for the year.

The weighted average common and common equivalent shares and fully diluted
shares outstanding as of December 31, 1995 was 398,704 for both calculations.
The weighted average common and common equivalent shares and fully diluted
shares outstanding as of December 31, 1994 were 394,206 and 396,764,
respectively. The weighted average common and common equivalent shares
outstanding at December 31, 1993 was 384,404 for both calculations.

NOTE 8 - PROFIT SHARING RETIREMENT PLAN

During 1994, the Company amended and restated the Salary Reduction 401(k) Profit
Sharing Retirement Plan to add features permitting employees to invest a portion
of their account balances in common stock of the Company. The new Employee Stock
Ownership Plan with 401(k) provisions (KSOP), which covers substantially all
employees, permits employee voluntary contributions and provides for
discretionary Company matching, basic and optional contributions. Employee
voluntary contributions, Company basic contributions and 50% of Company matching
contributions are fully vested at all times. Company optional contributions and
the remaining matching contributions vest over a seven-year period. The expense
associated with the plan amounted to $99,000 in 1995, $100,000 in 1994 and
$84,000 in 1993.

Also during 1994, the Company adopted nonqualified salary deferral and executive
supplemental income plans for certain officers and directors. The liability for
benefits to be provided under these plans is being accrued over the expected
period of service of the covered officers and directors. Plan expense totaled
$115,000 and $57,000 in 1995 and 1994, respectively. As an informal means of
funding these plans and to provide earnings to offset expected plan costs, the
Bank purchased life insurance policies on the lives of the covered officers and
directors. The Bank is both the owner and beneficiary of the life insurance
policies. The cash surrender value of these and other policies totaled $704,000
and $377,000 at December 31, 1995 and 1994, respectively.

NOTE 9 - STOCK OPTION PLAN

On April 6, 1994, the Board of Directors adopted a stock option plan authorizing
the grant of incentive stock options to key employees and nonstatutory stock
options to members of the Board. The maximum number of shares subject to option
is 71,820. The option exercise price is not less than the estimated fair market
value of the Company's stock at the date of grant. As of December 31, 1995, a
total of 71,820 options at an exercise price of $40 per share were outstanding.
No options were exercised in 1995 or 1994. The options expire if they have not
been exercised within a ten-year period.

NOTE 10 - FEDERAL INCOME TAXES (Continued)

The difference between the financial statement tax provision and amounts
computed by applying the statutory federal income tax rate is due principally to
the benefit of nontaxable interest on state and municipal obligations.

receivable and other assets in the accompanying consolidated balance sheets
consisted of the following (in thousands):

                                        ============        =========
</TABLE>


Deferred taxes arise primarily from differences in the recording, for financial
statement and tax reporting purposes, of bad debt deductions with respect to
deferred tax assets and depreciation expense with respect to deferred tax
liabilities. The Company has sufficient taxes paid in prior years to support
recognition of the net deferred tax asset.

NOTE 11 - COMMITMENTS AND CONTINGENCIES

The Company is a party to financial instruments with off-balance-sheet risk in
the normal course of business to meet financing needs of its customers. These
financial instruments include commitments to make loans. The Company's exposure
to credit loss in the event of nonperformance by the other party to the
financial instrument for commitments to make loans is represented by the
contractual amount of those instruments. The Company follows the same credit
policy to make such commitments as it uses for on-balance-sheet items.

As of December 31, 1995, outstanding loan commitments, customers' unused lines
of credit and standby letters of credit totaled approximately $13,667,000.

Since many commitments to make loans expire without being used, the amount does
not necessarily represent future cash commitments. Collateral obtained upon
exercise of the commitment is determined using management's credit evaluation of
the borrower and may include real estate, vehicles, business assets, deposits
and other items.

At December 31, 1995, federal regulations required the Bank to have $1,052,000
cash on hand or on deposit with the Federal Reserve.

NOTE 12 - DIVIDENDS

The Company's primary source of funds with which to pay dividends is The
Citizens National Bank of Urbana. The Bank is restricted by national banking
laws from paying dividends in any calendar year which exceed retained net
profits (as defined) for that year and the two preceding years, without prior
approval of the Comptroller of the Currency. This limitation does not currently
restrict the Company's ability to pay customary dividends.

NOTE 13 - ACQUISITION

Effective May 1, 1993, the Bank paid $1,750,000 to acquire the Farmers National
Bank of Plain City and Plain City Home and Savings Company, thereby assuming all
assets and liabilities of the acquired financial institutions. The acquisitions
have been accounted for using the purchase method of accounting and accordingly,
the acquired assets and liabilities have been recorded based on their estimated
fair value. The assets and liabilities acquired totaled approximately
$9,450,000. The effect of these acquisitions are included in the results of
operations, prospectively from May 1, 1993.

NOTE 14 - DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

On December 31, 1995, the Company was required to adopt SFAS No. 107,
"Disclosure about Fair Values of Financial Instruments." This standard
prescribes that the Company disclose the estimated fair values of its financial
instruments.

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which estimating that value is
practicable.

Cash and Short-term Investments: For short-term instruments, the carrying amount
is a reasonable estimate of fair value.

Investment Securities: For securities held as investments, fair value equals
quoted market price, if available. If a quoted market price is not available,
fair value is estimated using quoted market prices for similar instruments.

Loans: The fair value of loans 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 the same remaining maturities. Carrying value is
considered to approximate fair value for loans that contractually reprice at
intervals less than one year. The fair market value of commitments is not
material at December 31, 1995.

NOTE 14 - DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
(Continued)

Cash Surrender Value: The amount which would be received by the Company upon
cancellation of the insurance policies has been used as an estimate of fair
value.

Deposit Liabilities: The fair value of demand deposits, savings accounts and
certain money market deposits is the amount payable on demand at the reporting
date. The fair value of fixed-maturity certificates of deposit is estimated
using the rates currently offered for deposits of similar remaining maturities.

Securities Sold Under Agreements to Repurchase and Other Borrowed Funds: Because
of the short-term nature of these obligations, the carrying amount is a
reasonable estimate of fair value.

Accrued Interest Receivable and Payable: For accrued interest receivable and
payable, the carrying amount is a reasonable estimate of fair value.

The estimated fair values of the Bank's financial instruments at December 31,
1995 are as follows: (In thousands)

NOTE 14 - DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
(Continued)

Fair value estimates are made at a specific point in time, based on relevant
market information and information about the financial instrument. These
estimates do not reflect any premium or discount that could result from offering
for sale at one time the Company's entire holdings of a particular financial
instrument. Because no market exists for a significant portion of the Company's
financial instruments, fair value estimates are based on judgments regarding
future expected loss experience, current economic conditions, risk
characteristics of various financial instruments and other factors. These
estimates are subjective in nature and involve uncertainties and matters of
significant judgment and therefore cannot be determined with precision. Changes
in assumptions could significantly affect the estimates.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  March 31,1996


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed in the
preparation of the accompanying consolidated financial statements.

Basis of Presentation: The consolidated financial statements include the
accounts of CitNat Bancorp, Inc. (Company) and its wholly owned subsidiary, The
Citizens National Bank of Urbana (Bank). All material intercompany transactions
and balances have been eliminated. All information included in these interim
period financial statements is unaudited.

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

Statement of Cash Flows: For purposes of reporting cash flows, cash and cash
equivalents include cash, short-term interest-bearing deposits with financial
institutions and federal funds sold. Generally, federal funds are sold for
one-day periods. The Company reports net cash flows for customer loan
transactions, deposit transactions and short-term borrowings. For the three
months ended March 31, 1996 and 1995, the Company paid interest of $957 and $846
and income taxes of $24 and $0, respectively.

Investment Securities: Securities classified as held to maturity are those that
management has the positive intent and ability to hold to maturity. Securities
classified as available for sale are those that management intends to sell or
that would be sold for liquidity, investment management, or similar reasons,
even if management does not presently intend such a sale.

Securities held to maturity are stated at cost, adjusted for amortization of
premiums and accretion of discounts. Securities available for sale are carried
at fair value using the specific identification method. Unrealized gains and
losses are recorded as a net amount in a separate component of shareholders'
equity, net of tax effects. Gains or losses on dispositions are based on net
proceeds and the adjusted carrying amount of securities sold, using the specific
identification method.

Interest Income on Loans: Interest income on loans is accrued over the term of
the loans based on the principal balance outstanding. When substantial doubt
exists as to the collectibility of a loan, the interest accrual is discontinued.
Loan origination fees, net of direct loan origination costs, are deferred and
recognized over the life of the loan as a yield adjustment. The net amount
deferred is reported in the balance sheet as a reduction of loans.

                                  (Continued)

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  March 31,1996

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

The carrying values of impaired loans are 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. Other cash payments are
reported as reductions in carrying value, while increases or decreases due to
changes in estimates of future payments and due to the passage of time are
reported as part of the provision for loan losses.

Allowance for Possible Loan Losses: The allowance for possible loan losses,
which is reported as a deduction from loans, is available for loan charge-offs.
This allowance is increased by provisions charged to earnings and is reduced by
loan charge-offs, net of recoveries. The adequacy of the allowance is based on
management's evaluation of several key factors including information about
specific borrower situations, their financial position and collateral values,
current economic conditions, changes in the mix and levels of the various types
of loans, past charge-off experience, and other pertinent information. The
allowance for possible loan losses is based on estimates using currently
available information and ultimate losses may vary from current estimates due to
changes in circumstances. These estimates are reviewed periodically and, as
adjustments become necessary, they are reported in earnings in the periods in
which they become known. Charge-offs are made against the allowance for possible
loan losses when management concludes that loan amounts are likely to be
uncollectible.

On January 1, 1995, the Company adopted SFAS 114, "Accounting by Creditors for
Impairment of a Loan" and SFAS 118, "Accounting by Creditors for Impairment of a
Loan - Income Recognition and Disclosures." SFAS 114 specifies that allowances
for loan losses on impaired loans should be determined using the present value
of estimated future cash flows of the loan, discounted at the loan's effective
interest rate, or the fair value of the collateral. A loan is impaired when all
principal and interest amounts will not likely be collected according to the
loan contract. The impact of adoption of SFAS 114 and SFAS 118 on the financial
position or results of operations of the Company was not significant.

Premises and Equipment: Premises and equipment are stated at cost less
accumulated depreciation. Premises and equipment are depreciated on the
straight-line and declining-balance methods over the estimated useful lives of
the assets. Maintenance and repairs are expensed and major improvements are
capitalized.

Other Real Estate: Real estate acquired through foreclosure is initially
recorded at the lower of the recorded loan amount or the fair market value of
the asset received. If management later determines that the total capitalized
cost of the property cannot be recovered through sale or use, the loss is
recognized in the current period by a charge to income with a corresponding
writedown of the asset.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Per Share Amounts: The Company declared 1% stock dividends payable to
shareholders of record as of June 20, 1995 and November 21, 1995. Fractional
shares were paid in cash. These stock dividends resulted in the issuance of
3,704 and 3,735 shares of common stock, respectively. Dividends per share and
earnings per share amounts have been computed as though the additional shares
had always been outstanding.

In addition, earnings per share amounts take into consideration the dilutive
effects of the stock option plan adopted by the Board of Directors on April 6,
1994. Earnings per common share and common share equivalent has been computed
assuming the exercise of dilutive stock options, less the treasury shares
assumed to be purchased from the proceeds using the average market price of the
Company's stock for the period options were outstanding. Fully diluted earnings
per common share represents the additional dilution related to the stock options
due to the use of the market price as of the end of the year if it exceeds the
average price for the year.

The weighted average common and common equivalent shares and fully diluted
shares outstanding as of March 31, 1996 and 1995 were 396,863 and 398,927,
respectively.

NOTE 8 - PROFIT SHARING RETIREMENT PLAN

During 1994, the Company amended and restated the Salary Reduction 401(k) Profit
Sharing Retirement Plan to add features permitting employees to invest a portion
of their account balances in common stock of the Company. The new Employee Stock
Ownership Plan with 401(k) provisions (KSOP), which covers substantially all
employees, permits employee voluntary contributions and provides for
discretionary Company matching, basic and optional contributions. Employee
voluntary contributions, Company basic contributions and 50% of Company matching
contributions are fully vested at all times. Company optional contributions and
the remaining matching contributions vest over a seven-year period. The expense
associated with the plan amounted to $26,000 and $27,000 for the three months
ended March 31, 1996 and 1995, respectively.

Also during 1994, the Company adopted nonqualified salary deferral and executive
supplemental income plans for certain officers and directors. The liability for
benefits to be provided under these plans is being accrued over the expected
period of service of the covered officers and directors. Plan expense totaled
$35,000 and $27,000 for the three months ended March 31, 1996 and 1995,
respectively. As an informal means of funding these plans and to provide
earnings to offset expected plan costs, the Bank purchased life insurance
policies on the lives of the covered officers and directors. The Bank is both
the owner and beneficiary of the life insurance policies. The cash surrender
value of these and other policies totaled $697,000 at March 31, 1996.

NOTE 9 - STOCK OPTION PLAN

On April 6, 1994, the Board of Directors adopted a stock option plan authorizing
the grant of incentive stock options to key employees and nonstatutory stock
options to members of the Board. The maximum number of shares subject to option
is 71,820. The option exercise price is not less than the estimated fair market
value of the Company's stock at the date of grant. As of March 31, 1996, a total
of 71,820 options at an exercise price of $40 per share were outstanding. No
options were exercised during the three months ended March 31, 1996. The options
expire if they have not been exercised within a ten-year period.

NOTE 10 - FEDERAL INCOME TAXES

The Company files a consolidated federal income tax return. The Bank pays to the
Company its tax liability computed on a separate return basis. Taxes are
provided for in these interim period financial statements based upon the
effective tax rates expected to be incurred.

NOTE 11 - COMMITMENTS AND CONTINGENCIES

The Company is a party to financial instruments with off-balance-sheet risk in
the normal course of business to meet financing needs of its customers. These
financial instruments include commitments to make loans. The Company's exposure
to credit loss in the event of nonperformance by the other party to the
financial instrument for commitments to make loans is represented by the
contractual amount of those instruments. The Company follows the same credit
policy to make such commitments as it uses for on-balance-sheet items.

As of March 31, 1996, outstanding loan commitments, customers' unused lines of
credit and standby letters of credit totaled approximately $13,358,000.

Since many commitments to make loans expire without being used, the amount does
not necessarily represent future cash commitments. Collateral obtained upon
exercise of the commitment is determined using management's credit evaluation of
the borrower and may include real estate, vehicles, business assets, deposits
and other items.

At March 31, 1996, federal regulations required the Bank to have $1,067,000 cash
on hand or on deposit with the Federal Reserve.

NOTE 12 - DIVIDENDS

The Company's primary source of funds with which to pay dividends is The
Citizens National Bank of Urbana. The Bank is restricted by national banking
laws from paying dividends in any calendar year which exceed retained net
profits (as defined) for that year and the two preceding years, without prior
approval of the Comptroller of the Currency. This limitation does not currently
restrict the Company's ability to pay customary dividends.

NOTE 13 - DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments for which estimating that value is
practicable.

NOTE 13 - DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
(Continued)

Cash and Short-term Investments: For short-term instruments, the carrying amount
is a reasonable estimate of fair value.

Investment Securities: For securities held as investments, fair value equals
quoted market price, if available. If a quoted market price is not available,
fair value is estimated using quoted market prices for similar instruments.

Loans: The fair value of loans 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 the same remaining maturities. Carrying value is
considered to approximate fair value for loans that contractually reprice at
intervals of less than one year. The fair market value of commitments is not
material at December 31, 1995.

Cash Surrender Value: The amount which would be received by the Company upon
cancellation of the insurance policies has been used as an estimate of fair
value.

Deposit Liabilities: The fair value of demand deposits, savings accounts and
certain money market deposits is the amount payable on demand at the reporting
date. The fair value of fixed-maturity certificates of deposit is estimated
using the rates currently offered for deposits of similar remaining maturities.

Securities Sold Under Agreements to Repurchase and Other Borrowed Funds: Because
of the short-term nature of these obligations, the carrying amount is a
reasonable estimate of fair value.

Accrued Interest Receivable and Payable: For accrued interest receivable and
payable, the carrying amount is a reasonable estimate of fair value.

Fair value estimates are made at a specific point in time, based on relevant
market information and information about the financial instrument. These
estimates do not reflect any premium or discount that could result from offering
for sale at one time the Company's entire holdings of a particular financial
instrument. Because no market exists for a significant portion of the Company's
financial instruments, fair value estimates are based on judgments regarding
future expected loss experience, current economic conditions, risk
characteristics of various financial instruments and other factors. These
estimates are subjective in nature and involve uncertainties and matters of
significant judgment and therefore cannot be determined with precision. Changes
in assumptions could significantly affect the estimates.

[KPMG PEAT MARWICK LLP LOGO]

The Board of Directors
Third Financial Corporation:

We have audited the accompanying consolidated balance sheets of Third

1994, and the related consolidated statements of income, shareholders' equity

three-year period ended September 30, 1995 in conformity with generally
accepted accounting principles.

                   THIRD FINANCIAL CORPORATION AND SUBSIDIARY
              Notes to Consolidated Financial Statements, Continued

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The  accounting and reporting policies of Third Financial Corporation (the
         Company) conform to generally accepted accounting principles and to
         general practice within the savings and loan industry. The following is
         a description of the more significant policies the Company follows in
         preparing and presenting its financial statements.

(A) PRINCIPLES OF CONSOLIDATION

    The  accompanying consolidated financial statements include the accounts of
         the Company and Third Savings, its wholly owned subsidiary. All
         significant intercompany transactions and balances are eliminated in
         consolidation.

(B) CASH AND CASH EQUIVALENTS

    For  purposes of reporting cash flows, cash and cash equivalents include
         cash and amounts due from depository institutions and interest-bearing
         deposits in other banks. Interest-bearing deposits in other banks
         include certificates of deposit with original maturities of three
         months or less.

(C) CERTIFICATES OF DEPOSIT

    Certificates of deposit include certificates with original maturities of
         greater than three months.

(D) MORTGAGE-BACKED AND OTHER INVESTMENT SECURITIES

    The  Company adopted the provisions of Statement of Financial Accounting
         Standards (SFAS) No. 115, Accounting for Certain Investments in Debt
         and Equity Securities (Statement 115) effective October 1, 1994. Under
         Statement 115, the Company classifies its marketable debt and equity
         securities in one of three categories: trading, available for sale, or
         held to maturity.

    Securities are classified as securities held to maturity based on
         management's intent and the Company's ability to hold them to maturity.
         Such securities are stated at cost, adjusted for unamortized purchase
         premiums and discounts. Purchase premiums and discounts are amortized
         over the life of the related security using a method which approximates
         the level yield method.

    Securities that are bought and held principally for the purpose of selling
         them in the near term are classified as trading account securities,
         which are carried at market value. Realized gains and losses and gains
         and losses from marking the portfolio to market value are included in
         trading revenue. The Company holds no trading assets at September 30,
         1995.

    Securities not classified as securities held to maturity or trading account
         securities are classified as securities available for sale, and are
         stated at fair value. Unrealized gains and losses are excluded from
         earnings, and are reported as a separate component of shareholders'
         equity, net of taxes. Such securities include those that may be sold in
         response to changes in interest rates, changes in prepayment risk or
         other factors.

    Gains or losses on the sale of securities are credited or charged to
         earnings when realized based on the specific identification method.

                                                                     (Continued)

              Notes to Consolidated Financial Statements, Continued


    Federal Home Loan Bank stock is valued at cost. This investment is
         maintained in accordance with Federal Home Loan Bank regulations.

(E) PROVISIONS FOR LOSSES

    Management provides for and determines the adequacy of the allowance for
         loan losses based on the Company's past loan loss experience, review of
         individual problem loans, inherent risks in the portfolio, adverse
         situations that may affect the borrower's ability to repay, the
         estimated value of the underlying collateral and current economic
         conditions.

    In   addition, various regulatory agencies, as an integral part of their
         examination process, periodically review the Company's allowances for
         losses on loans. Such agencies may require the Company to recognize
         additions to the allowances based on their judgments about information
         available to them at the time of the examination. In the opinion of
         management, the allowance, when taken as a whole, is adequate to absorb
         reasonably foreseeable losses.

    In   May, 1993, the Financial Accounting Standards Board (FASB) issued SFAS
         No. 114, Accounting by Creditors for Impairment of Loans (Statement
         114). Statement 114 is applicable to all creditors and to all types of
         lending except for loans that are measured at fair value or at the
         lower of cost or fair value in accordance with specialized industry
         practice. The statement applies to all loans that are restructured in a
         troubled debt restructuring involving a modification of terms. It
         requires that impaired loans be measured based on the present value of
         expected future cash flows discounted at the loan's effective interest
         rate or, as a practical expedient, at the loan's observable market
         price or the fair value of the collateral if the loan is collateral
         dependent.

    Statement 114 applies to financial statements for fiscal years beginning
         after December 15, 1994. Statement 114 was amended in October of 1994
         by SFAS No. 118, Accounting by Creditors for Impairment of a Loan -
         Income Recognition and Disclosure. This amendment allows for interest
         income to be recognized by existing methods and deletes those income
         recognition provisions described in Statement 114. Management does not
         believe that the implementation of these statements will have a
         materially adverse effect on the operations of the Company.

    Accrual of interest on potential problem loans is excluded from income by an
         offsetting increase in a specific allowance for loss when, in the
         opinion of management, this is warranted.

(F) UNEARNED LOAN DISCOUNTS AND LOAN ORIGINATION FEES

    In   accordance with the provisions of SFAS No. 91, Accounting for
         Nonrefundable Fees and Costs Associated with Originating or Acquiring
         Loans and Initial Direct Costs of Leases, the Company defers loan
         origination fees and initial direct origination costs of loans. Such
         fees and costs are accreted into interest income using the level yield
         method over the contractual lives of the loans. This accretion is
         suspended on nonperforming loans.

                                                                     (Continued)

(g)     LOANS HELD FOR SALE

        Mortgage loans originated and intended for the secondary market are
            carried at the lower of cost or estimated market value in the
            aggregate.

(h)     LOAN SERVICING

        The Company services for investors mortgage loans that are not included
            in the consolidated balance sheet. Fees earned for servicing loans
            owned by investors are reported as income when the related mortgage
            loan payments are collected. Loan servicing costs are charged to
            expense as incurred.

        In May 1995, the FASB issued SFAS No. 122, Accounting for Mortgage
            Servicing Rights (Statement 122). This statement amends SFAS No. 65,
            Accounting for Certain Mortgage Banking Activities, to require a
            mortgage banking enterprise to recognize as separate assets the
            rights to service mortgage loans for others regardless how those
            servicing rights are acquired. A mortgage banking enterprise that
            acquires mortgage servicing rights through either the purchase or
            origination of mortgage loans and subsequently sells or securitizes
            those loans with servicing rights retained should allocate the total
            cost of the mortgage loans between the mortgage servicing rights and
            the loans themselves, based on their relative fair values.

        This statement requires a mortgage banking enterprise to assess its
            capitalized mortgage servicing rights for impairment based on the
            fair value of such rights. A mortgage banking enterprise should
            stratify its capitalized mortgage servicing rights upon adoption of
            this statement based on one or more of the primary risk
            characteristics of the underlying loans. Impairment should be
            recognized through a valuation allowance for each category of loans.

        This statement is to be applied prospectively in fiscal years beginning
            after December 15, 1995, to transactions in which an entity sells or
            securitizes mortgage loans with servicing rights retained and to
            impairment evaluations of all amounts capitalized as mortgage
            servicing rights, including those purchased before the adoption of
            this statement. Earlier application is encouraged. Retroactive
            capitalization of mortgage servicing rights retained in transactions
            incurred before the adoption of this statement is prohibited. The
            Company will adopt the provisions of Statement 122 in fiscal 1997
            and does not anticipate the impact of the adoption to be material.


(i)     DEPRECIATION

        Depreciation of office properties and equipment is computed on a
            straight-line basis over the estimated useful lives of the related
            assets.

(J) REAL ESTATE OWNED

    Property acquired by foreclosure or deed in lieu of foreclosure (REO) is
         stated at the lower of cost or fair value at the date of acquisition.
         Subsequent to the acquisition date, charges to income are made if it is
         determined that the carrying value exceeds the fair value less
         estimated costs to sell. Costs to develop or improve the property are
         capitalized; costs of holding the property are charged to expense. The
         specific-identification method is used to determine gain or loss on the
         sale of REO.

    Loans secured by property, for which there is an indication that the
         borrower no longer has the ability to repay the loan and it is doubtful
         that equity will be rebuilt in the foreseeable future, are classified
         as in-substance foreclosures and accounted for as REO.

(K) FEDERAL INCOME TAXES

    In   February 1992, the FASB issued SFAS No. 109, Accounting for Income
         Taxes (Statement 109). Statement 109 requires a change from the
         deferred method of accounting for income taxes under Accounting
         Principles Bulletin (APB) Opinion 11 to the asset and liability method
         of accounting for income taxes. Under the asset and liability method of
         Statement 109, deferred tax assets and liabilities are recognized for
         the future tax consequences attributable to differences between the
         financial statement carrying amounts of existing assets and liabilities
         and their respective tax bases. Deferred tax assets and liabilities are
         measured using enacted tax rates expected to apply to taxable income in
         the years in which those temporary differences are expected to be
         recovered or settled. Under Statement 109, the effect on deferred tax
         assets and liabilities of a change in tax rates is recognized in income
         in the period that includes the enactment date.

    Effective October 1, 1993, the Company adopted Statement 109 and has
         reported the cumulative effect of that change in the method of
         accounting for income taxes in the 1994 consolidated statement of
         income.

    Pursuant to the deferred method under APB Opinion 11, which was applied in
         1993 and prior years, deferred income taxes are recognized for income
         and expense items that are reported in different years for financial
         reporting purposes and income tax purposes using the tax rate
         applicable for the year of the calculation. Under the deferred method,
         deferred taxes are not adjusted for subsequent changes in tax rates.

(L) EARNINGS PER SHARE

    Earnings per share have been computed using the "if-converted" method by
         dividing net income applicable to common stock by the average number of
         shares of common stock and common stock equivalents outstanding, net of
         shares assumed to be repurchased using the treasury stock method.
         Common stock equivalents arise from the assumed conversion of
         outstanding stock options. The average number of shares of common stock
         and common stock equivalents outstanding was 1,184,243, 1,252,776 and
         1,271,028 in 1995, 1994 and 1993, respectively. For the year ended
         September 30, 1993, earnings per share are based on historical earnings
         from the date of conversion, March 25, 1993 through September 30, 1993.

               Certain amounts in the 1994 and 1993 consolidated financial
statements have been reclassified to conform with the 1995 presentation.

(2)     SECURITIES AVAILABLE FOR SALE

        As  discussed in note 1(d), the Company adopted Statement 115 as of
            October 1, 1994. Upon adoption, the Company recorded $230,800 in
            unrealized gains on securities available for sale, net of federal
            income taxes, as a component of shareholders' equity.

        The amortized cost and approximate market value of securities available
for sale at September 30, 1995 are summarized as follows:

    The  negative provision for loan losses for the years ended September 30,
         1995 and 1994 and the corresponding decrease in the allowance for loan
         losses at September 30, 1995 and 1994 is due to the successful
         disposition of several loans specifically reserved for at September 30,
         1994 and 1993 as well as an overall improvements in delinquency rates
         for the underlying loan portfolios.

  As discussed in note 1(k), the Company adopted Statement 109 as of October 1,
    1993. The cumulative effect of this change in accounting for income taxes of
    $600,000 was determined as of October 1, 1993 and was reported separately in
    the consolidated statement of earnings for the year ended September 30,
    1994. Prior years' financial statements were not restated to apply the
    provisions of Statement 109.

  The actual income tax expense for 1995, 1994 and 1993 differs from the
    "expected" amounts for those years (computed by applying the statutory U.S.
    federal corporate tax rate of 34% to income before federal income taxes) as
    follows:

  The Company has not established a valuation allowance at September 30, 1995
    and 1994 as it believes that all deferred tax assets are fully realizable.
    In assessing the realizability of deferred tax assets, management considers
    whether it is more likely than not that some portion or all of the deferred
    tax assets will not be realized. Management considers the scheduled reversal
    of deferred tax liabilities and tax planning strategies in making the
    assessment.

  The components of deferred federal income tax expense (benefit) for the year
    ended September 30, 1993 is as follows:

  The Company and its subsidiary file a consolidated federal income tax return
    on a calendar year basis. The Company is permitted under the Internal
    Revenue Code (the Code) to deduct an annual addition to a reserve for bad
    debts in determining taxable income, subject to certain limitations. Bad
    debt deductions for income tax purposes are included in taxable income of
    later years only if the bad debt reserve is used subsequently for purposes
    other than to absorb bad debt losses. Because the Company does not intend to
    use the reserve for purposes other than to absorb losses, no deferred income
    taxes have been provided prior to 1987. Retained earnings at September 30,
    1995 includes approximately $5,200,000 representing such bad debt deductions
    for which no deferred income taxes have been provided.


(11) EMPLOYEE BENEFIT PLANS

     PENSION PLAN

  The Company maintains a defined benefit pension plan for substantially all of
    its employees. Pension expense for 1995, 1994 and 1993 is $81,915, $105,174,
    and $74,715, respectively. The plan benefits are funded through a trust. The
    Company's policy is to fund pension costs in accordance with Internal
    Revenue Service requirements.

EMPLOYEE STOCK OWNERSHIP PLAN

  Effective October 1992, the Company established the Employee Stock Ownership
    Plan (ESOP) which purchased 86,450 shares of common stock of the Company in
    March 1993. The ESOP was capitalized with a loan from the Company for
    $864,500.

  Third Savings intends to make contributions to the ESOP in an amount to be
    determined by the Board of Directors, but not less than the amount needed to
    pay any currently maturing obligations under the loan made to the ESOP. The
    loan requires semiannual payments and has a term of five years. Benefits
    under the ESOP become 100% vested after five years of service and prior
    service is includable. During 1995 and 1994 and 1993, Third Savings made a
    contribution to the ESOP in the amount of $206,616, $217,183 and $113,250,
    respectively, and recognized compensation expense of $142,608, $142,801 and
    $86,450, respectively. Compensation expense for 1995 and 1994 differs from
    the required principal payment of $172,900 due to dividends on unallocated
    ESOP shares which were applied to the outstanding principal balance.
    Interest payments are eliminated in consolidation.

  The Company adopted the provisions of The American Institute of Certified
    Public Accountant's Statement of Position 93-6, Employers Accounting for
    Employee Stock Ownership Plans, as of October 1, 1994. This statement
    requires that the company recognize compensation expense related to shares
    allocated in the current year to the extent current market value of the
    shares exceeds the cost of those shares to the ESOP. During 1995, the
    Company recognized $170,198 in compensation expense related to this change
    in accounting for the ESOP.

  At September 30, 1995, 40,399 unallocated shares remain in the ESOP and will
    be allocated to participants over the next 2 1/2 years.

MANAGEMENT RECOGNITION AND RETENTION PLAN

  The Company's Board of Directors established Management Recognition and
    Retention Plan and Trusts (MRRPs) as a method of providing key employees and
    directors with a proprietary interest in the Company in a manner designed to
    encourage such individuals to remain with the Company. The awards for
    outside directors and employees vest at the annual rate of 33 1/3% and 20%,
    respectively, of the restricted stock granted. The unearned compensation
    under the MRRPs is recorded as a reduction of shareholders' equity and is
    amortized to operations as the shares are earned. During 1995 and 1994, the
    Company recognized $83,931 and $180,713, respectively, in compensation
    expense related to the MRRPs.

  In accordance with approval from the Office of Thrift Supervision, Third
    Savings contributed $642,184 to the MRRPs for the purpose of purchasing
    common stock. On March 26, 1993, the MRRP trusts purchased 40,867 shares of
    common stock. At September 30, 1995, 29,115 shares have been awarded to
    directors and employees and 11,752 shares remain reserved in the trusts. At
    September 30, 1994, 29,831 shares had been awarded to directors and
    employees and 11,036 shares remained reserved in the trusts.

STOCK OPTION AND INCENTIVE PLAN

  In connection with the conversion to a stock savings and loan association, the
    Company's Board of Directors adopted a stock option and incentive plan (the
    Plan). Under the Plan, options to purchase a total of 123,500 shares of
    common stock may be granted to the Company's directors and officers.

  All of the options are nontransferable stock options and have a term of 10
    years. Options granted to outside directors and employees vest at the annual
    rate of 33 1/3% and 20% per year, respectively, except options granted for
    11,115 shares which vested immediately upon shareholder approval in August
    1993.

(12) FINANCIAL INSTRUMENTS

OFF-BALANCE SHEET RISK

  The Company is a party to financial instruments with off-balance sheet risk in
    the normal course of business to meet the financing needs of its customers
    and to reduce its exposure to fluctuations in interest rates. These
    financial instruments involve, to varying degrees, elements of credit risk
    that are not recognized in the balance sheet.

  The Company's exposure to credit loss in the event of nonperformance by the
    other party to the financial instrument for commitments to extend credit and
    recourse agreements is represented by the contractual amount of those
    instruments. The Company uses the same credit policies in making these
    commitments and obligations as it does for on-balance sheet instruments. In
    extending commitments, the Company evaluates each customer's credit
    worthiness on a case-by-case basis. The amount of collateral obtained, if
    deemed necessary by the Company upon extension of credit, is based on
    management's credit evaluation of the counterparty.

  Commitments to extend credit are agreements to lend to a customer as long as
    there is no violation of any condition established in the contract.
    Commitments generally have fixed expiration dates or other termination
    clauses, and may require payment of a fee. Since a portion of the
    commitments are expected to expire without being drawn upon, the total
    commitment amounts do not necessarily represent future cash requirements.

  The Company uses forward commitments to sell residential first mortgage loans
    which are entered into for the purpose of reducing the market risk
    associated with originating loans for sale. The types of risk that may arise
    are from the possible inability of the Company to fulfill the contracts or
    adverse movement of market rates.

  Financial instruments with off-balance sheet risk as of September 30, 1995
    were approximately as follows:

CONCENTRATION OF CREDIT RISK

  The Company considers its primary market area for lending and savings
    activities to be the immediate geographic area of Miami County, Ohio and
    surrounding counties. Although the Company has a diversified loan portfolio,
    a substantial portion of its debtors' ability to honor their contractual
    obligation is reliant upon the economic stability of the region.

LEGAL CONTINGENCIES

  At September 30, 1995, the Company was party, both as plaintiff and defendant,
    to legal actions and claims arising out of the normal conduct of its
    business. It is the best judgment of management that the financial position
    of the Company will not be materially affected by the final outcome of these
    legal proceedings.

(13) STOCK CONVERSION

  On March 25, 1993, Third Savings completed a conversion from a mutual to stock
    form of ownership whereby Third Savings converted from an Ohio mutual
    savings and loan association to an Ohio stock savings and loan association
    with the concurrent formation of a holding company. Pursuant to the
    conversion, shares of capital stock of the holding company were offered to
    eligible account holders and such other persons as defined by the plan. The
    price was determined by an independent appraisal of Third Savings and
    reflected its estimated pro forma market value, as converted. As part of the
    conversion, nontransferable subscription rights to purchase stock were
    offered first to the Company's tax-qualified employee plans; then to
    eligible savings account holders; then, to the extent the stock was
    available, to other Company members; and then to the directors, officers,
    and employees.

  Savings account holders and borrowers do not have voting rights in the
    Company. Voting rights are vested exclusively with the stockholders of the
    Company. Savings deposits continue to be insured by the Savings Association
    Insurance Fund (SAIF) of the Federal Deposit Insurance Corporation.

  All costs associated with the conversion were deferred and deducted from the
    proceeds of the sale of stock. The Company issued 1,235,000 shares of $.01
    par value common stock for proceeds totaling $12,350,000. Costs of $510,000
    related to the conversion were deducted from additional paid-in capital,
    resulting in net proceeds of $11,840,000.

  At the time of conversion, Third Savings established a "Liquidation Account"
    in an amount equal to Third Savings' net worth as of September 30, 1992. The
    Liquidation Account is maintained for the benefit of depositors who continue
    to maintain their deposits in Third Savings after conversion. In the event
    of a complete liquidation (and only in such an event), each eligible
    depositor will be entitled to receive a liquidation distribution from the
    Liquidation Account, in the proportionate amount of the then-current
    adjusted balance for deposits then held, before any liquidation distribution
    may be made with respect to the stockholders. Except for the purchase of
    stock and payment of dividends by the Company, the existence of the
    liquidation account will not restrict use or application of net worth.

  Third Savings may not declare or pay a cash dividend to the Company if the
    effect would cause the net worth of Third Savings to be reduced below either
    the amount required for the Liquidation Account or the net worth requirement
    imposed by the Office of Thrift Supervision (OTS), and, if all fully
    phased-in capital requirements continue to be met, may not declare or pay a
    cash dividend in an amount in excess of Third Savings' net earnings for the
    fiscal year in which the dividend is declared plus one-half of the surplus
    over the fully phased-in capital requirements, without prior approval of the
    OTS. OTS approval is required for Third Savings to pay dividends in excess
    of these limitations.

(15) REGULATORY REQUIREMENTS

  Regulations currently require thrift institutions to have a minimum 1.5%
    tangible capital ratio, a 3% core capital ratio, and an 8% risk-based
    capital ratio. Third Savings currently meets its minimum regulatory capital
    requirements and management believes it will continue to meet them in the
    future.

  On December 19, 1992, the prompt corrective action regulations of the Federal
    Deposit Insurance Corporation (FDIC) Improvement Act became effective. These
    regulations define specific capital categories based on an institution's
    capital ratios. The capital categories are "well capitalized," "adequately
    capitalized," "undercapitalized," "significantly undercapitalized" and
    "critically undercapitalized." Institutions categorized as
    "undercapitalized" or worse are subject to certain restrictions, including
    the requirement to file a capital plan with the Office of Thrift Supervision
    (OTS), prohibitions on the payment of dividends and management fees,
    restrictions on executive compensation and increased supervisory monitoring,
    among other things. Other restrictions may be imposed on the institution
    either by the OTS or the FDIC, including requirements to raise additional
    capital, sell assets or sell the entire institution. Once an institution
    becomes "critically undercapitalized" it is generally placed in receivership
    or conservatorship within 90 days.

  To be considered "well capitalized," an institution must generally have a
    leverage ratio of at least 5%, a Tier 1 risk-based capital ratio of at least
    6% and a total risk-based capital ratio of at least 10%.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies followed by Third Financial Corporation (the
Company) and its wholly owned subsidiary, The Third Savings and Loan Company
(Third Savings or the Bank), for interim financial reporting are consistent with
the accounting policies followed for annual financial reporting. All adjustments
which are, in the opinion of management, necessary for a fair presentation of
the results for the periods reported have been included in the accompanying
unaudited consolidated financial statements and all such adjustments are of a
normal recurring nature. The accompanying financial statements do not purport to
contain all the necessary financial disclosures required by generally accepted
accounting principles that might otherwise be necessary in the circumstances and
should be read in conjunction with the 1995 financial statements and notes
thereto of Third Financial Corporation for the year ended September 30, 1995.

NOTE 2 - CONSUMMATION OF THE CONVERSION TO A STOCK SAVINGS AND LOAN
COMPANY

On March 25, 1993, Third Financial Corporation completed the stock subscription
offering. The conversion was consummated with the sale of common stock in an
amount equal to the market value of Third Savings after giving effect to the
stock conversion. The sale of the subscription offering resulted in the issuance
of 1,235,000 shares of common stock, raising net proceeds of $11.8 million. In
accordance with the Plan of Conversion, $5.9 million of the proceeds were
utilized to purchase 100% of the stock of The Third Savings and Loan Company in
conjunction with its conversion from a mutual savings and loan company to a
stock savings and loan company.

NOTE 3 - LOANS RECEIVABLE

Loans receivable is net of the allowance for loan losses of $1,181,777 at March
31, 1996 and $1,196,550 at September 30, 1995.

NOTE 4 - REAL ESTATE OWNED

September 30, 1995.

NOTE 5 - DIVIDENDS

A quarterly cash dividend of $.17 per common share was declared to stockholders
of record on February 15, 1996, payable on February 29, 1996. A quarterly cash
dividend of $.15 per common share was declared to stockholders of record on
November 16, 1995, payable on November 30,1995.

NOTE 6 - EARNINGS PER SHARE

Earnings per common share is calculated by dividing net income by the weighted

upon exercise of dilutive options outstanding, excluding treasury stock. The
weighted average number of common and common equivalent shares outstanding for
the three months ended March 31, 1996 and March 31, 1995, were 1,187,234 and
1,177,336, respectively. The weighted average number of common and common
equivalent shares outstanding for the six months ended March 31, 1996 and March
31, 1995, were 1,190,337 and 1,184,532, respectively.

NOTE 7 - EMPLOYEE BENEFIT PLANS

Stock Option and Incentive Plan:

In connection with the conversion to a stock savings and loan association, the
Company's Board of Directors adopted a stock option and incentive plan (the
Plan). Under the Plan, options to purchase a total of 123,500 shares of common
stock may be granted to the Company's directors and officers.

On March 25, 1993, upon consummation of the conversion of Third Savings, stock
options were granted for the purchase of 106,908 shares, exercisable at the
market price at the date of grant of $10.00 per share. All of the options are
nontransferable stock options and have a term of 10 years. Options granted to
outside directors and employees vest at the annual rate of 33 1/3% and 20% per
year, respectively, except options granted of 11,115 shares which vested
immediately upon shareholder approval in August 1993. In December 1995, 5,800
options were exercised. At March 31, 1996, options remain outstanding for
105,476 shares.

Management Recognition and Retention Plan:

The Board of Directors of the Company established Management Recognition and
Retention Plan and Trusts (MRRPs) as a method of providing key officers and
directors with a proprietary interest in the Company in a manner designed to
encourage such individuals to remain with the Company. The awards for outside
directors and management vest at the annual rate of 33 1/3% and 20%,
respectively, of the restricted stock granted. The unearned compensation under
the MRRPs is recorded as a reduction of shareholders' equity and is amortized to
operations as the shares are earned. During the three months ended March 31,
1996, the Company recognized $13,747 in compensation expense related to the
MRRPs, and $27,494 for the six months ended March 31, 1996.

In accordance with approval from the Office of Thrift Supervision, the Bank
contributed $642,184 to the MRRPs for the purpose of purchasing common stock. On
March 26, 1993, the MRRP trusts purchased 40,867 shares of common stock, at an
average price of $15.71, in the open market. At March 31, 1996, 29,115 shares
have been awarded to directors and employees and 11,752 shares remain reserved
in the trusts.

Employee Stock Ownership Plan:

Effective October, 1992, the Company established the Employee Stock Ownership
Plan (ESOP) which purchased 86,450 shares of common stock of the Company in
March 1993. The ESOP was capitalized with a loan from the Company for $864,500.

Third Savings intends to make contributions to the ESOP in an amount to be
determined by the Board of Directors, but not less than the amount needed to pay
any currently maturing obligations under the loan made to the ESOP. The loan
requires semi-annual payments and has a term of five years. Benefits under the
ESOP become 100% vested after five years of service and prior service is
includable. Third Savings recognized, for the ESOP, compensation expense of
$43,205 for the three months ended March 31, 1996, and $86,450 for the six
months ended March 31, 1996.

NOTE 8 - CHANGE IN ACCOUNTING STANDARDS

In May 1993, the FASB issued Statement of Financial Accounting Standards No. 115
(SFAS No. 115), Accounting for Certain Investments in Debt and Equity
Securities. SFAS No. 115 addresses the accounting and reporting for investments
in equity securities that have readily determinable fair values and all
investments in debt securities. Under this statement, debt securities may be
reported at amortized cost only if there is the positive intent and ability to
hold the security to maturity. The Company adopted SFAS No. 115 as of October 1,
1994, the impact was an increase to shareholder's equity of $252,881, net of
tax, for the period ended March 31, 1996.

                                      F-66
<PAGE>   132
The Financial Accounting Standards Board ("FASB") agreed to permit companies a
one-time reclassification for investment securities under SFAS No. 115. This
one-time reclassification had to occur before December 31, 1995. As such,
Management reclassified $9.6 million in securities classified as
held-to-maturity, to securities classified as available for sale, to provide
greater flexibility in the management of the investment portfolio.

In November 1993, the AICPA issued Statement of Position 93-6 (SOP 93-6),
Employers' Accounting for Employee Stock Ownership Plans. Under SOP 93-6, when
shares acquired by the Plan after December 31, 1992 are allocated to employees,
expense is recorded using fair value of the shares. The Company adopted SOP 93-6
as of October 1, 1994, the Company recognized $83,208 as compensation expense
for the three months ended March 31, 1996, and $153,450 for the six months ended
March 31, 1996.

In May, 1993, the FASB issued SFAS No. 114, Accounting by Creditors for
Impairment of a Loan (Statement 114). Statement 114 applies to financial
statements for fiscal years beginning after December 15, 1994. Statement 114 was
amended in October of 1994 by SFAS No. 118, Accounting by Creditors for
Impairment of a Loan - Income Recognition and Disclosure. This amendment allows
for interest income to be recognized by existing methods and deletes those
income recognition provisions described in Statement 114. The Company adopted
the provisions of this statement during the quarter ended December 31, 1995. The
Company did not have a material amount of impaired loans as of March 31, 1996.
However, refer to the discussion of the Bennett Funding loans in the Management
Discussion and Analysis section of this 10-Q. The Company had no commercial
loans or commercial real estate loans 90 days past due as of March 31, 1996.

In October 1995, the FASB issued SFAS No. 123, Accounting for Stock-Based
Compensation (Statement 123). Statement 123 applies to all transaction in which
an entity acquires goods or services by issuing equity instruments or by
incurring liabilities where the payment amounts are based on the entity's common
stock price, except for employee stock ownership plans. Statement 123 is
effective for fiscal years beginning after December 15, 1995. The Company has
not yet determined its method of adoption of Statement 123 and it's not required
to do so until October 1, 1996.

NOTE 9 - TREASURY STOCK

In Fiscal 1994, the Company announced its intention to acquire a total of 10
percent of the Company's common stock, subject to market conditions. The
repurchased stock will be available for general corporate purposes, including
the issuance of shares in connection with the exercise of stock options. At
March 31, 1996, Third Financial held 99,046 shares at a cost of $1,791,986.

<PAGE>   137
           and CitNat Options shall, upon surrender of the certificate or
           certificates formerly representing such CitNat Common Stock or
           delivery of documentation regarding the exchange and cancellation of
           CitNat Options, as the case may be, be paid cash without interest by
           Security for such fractional share(s). The cash paid for each
           fractional share shall be the same fraction of the average bid and
           asked closing price per share of Security Common Stock on the Closing

       (c) As soon as practicable, but not later than ten (10) days after the
           time the Merger shall become effective, and subject to the provisions
           set forth above relating to the fractional shares, Security, or an
           Exchange Agent designated thereby and approved by CitNat, will
           distribute to the former holders of CitNat Common Stock in exchange
           for and upon surrender for cancellation by such holders of a
           certificate or certificates formerly representing shares of CitNat
           Common Stock the certificate(s) for shares of Security Common Stock
           in accordance with the Exchange Ratio and any cash payment in lieu of
           fractional shares. Each certificate formerly representing CitNat
           Common Stock (other than certificates representing shares of CitNat
           Common Stock subject to the rights of dissenting shareholders) shall
           be deemed for all purposes to evidence the ownership of the number of
           whole shares of Security Common Stock and cash for fractional share
           interests in Security Common Stock into which such shares have been
           converted pursuant to the Exchange Ratio. Until surrender of the
           certificate or certificates formerly representing shares of CitNat
           Common Stock, the holder thereof shall not be entitled to receive any
           dividend or other payment or distribution payable to holders of
           Security Common Stock. Upon such surrender (or in lieu of surrender
           other provisions reasonably satisfactory to Security as are made as
           set forth in the next following paragraph), there shall be paid to
           the person entitled thereto the 

                                      A-5
<PAGE>   138
           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 shares of Security Common
           Stock 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 CitNat 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 CitNat Common Stock may have as dissenting shareholders
           pursuant to the Ohio General Corporation Law) and except as
           aforesaid, their sole rights shall be to exchange said certificates
           for certificates for shares of Security Common Stock in accordance
           with this Merger Agreement. 

           Certificates formerly representing shares of CitNat Common Stock
           surrendered for cancellation by each shareholder entitled to exchange
           shares of CitNat Common Stock for shares of Security Common Stock by
           reason of the Merger shall be accompanied by such appropriate
           instruments of transfer as Security may reasonably require, provided,
           however, that if there be delivered to Security by any person who is
           unable to produce any such certificate formerly representing shares
           of CitNat Common Stock for transfer (i) evidence to the reasonable
           satisfaction of Security that any such certificate has been lost,
           wrongfully taken or destroyed, and (ii) such indemnity agreement as
           reasonably may be requested by Security to save it harmless, and
           (iii) evidence to the reasonable satisfaction of Security 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 shares of Security Common Stock pursuant
           to this Merger Agreement,

                                      A-6
<PAGE>   139

                  then Security, 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 shares of Security
                  Common Stock which such person would have been entitled to
                  receive upon surrender of each such lost, wrongfully taken or
                  destroyed certificate representing shares of CitNat Common
                  Stock.

       (d) Holders of CitNat Options shall execute such documents as Security
           shall reasonably request to evidence the conversion of their CitNat
           Options to shares of Security Common Stock as herein provided for.

8.       Board of Directors. The Board of Directors of Security as constituted
         at the time the Merger shall become effective shall serve as the Board
         of Directors of Security as the Surviving Corporation plus one
         additional member from CitNat's board of directors to be named by
         Security.

9.       Discussions with Others. Subject to their fiduciary duties, CitNat or
         its officers, directors or agents will not solicit inquiries or
         proposals or initiate any discussions or negotiations leading to any
         acquisition or purchase of all or a substantial portion of the assets
         or stock of CitNat or Citizens Bank or any merger or consolidation of
         CitNat or Citizens Bank or with any third party without prior written
         notice to Security, so long as this Agreement is pending.

10.      Undertakings of the Parties. Security and CitNat further agree as
         follows:

         (a)  This Merger Agreement shall be submitted to the shareholders of
              CitNat and, if required by law, Security for approval and adoption
              at separate meetings to be called and held in accordance with law
              and the Articles of Incorporation and Code of Regulations of
              CitNat and Security.

         (b)  Security and CitNat will cooperate in the preparation by Security
              of the application to the Board of Governors of the Federal
              Reserve System (the 

                                      A-7
<PAGE>   140
              "Board") under the appropriate provisions of Section 3 of the Bank
              Holding Company Act of 1956, as amended, and to any other state or
              federal regulatory agency which may be required to facilitate the
              Merger. Security will file such applications within forty-five
              (45) days after the date of this Merger Agreement and shall afford
              CitNat and its counsel reasonable opportunity to comment on the
              applications prior to filing. Security and CitNat will cooperate
              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 Merger Agreement. The CitNat
              Proxy Statement will not be mailed to shareholders of CitNat until
              such time as the Board of Directors of CitNat has approved the
              CitNat Proxy Statement.

         (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.
              Security shall promptly prepare and file at no expense to CitNat:
              (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 shares of
              Security Common Stock to be issued in connection with the
              transactions contemplated by this Agreement. 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"). Security will also take any
              action required to be taken under any applicable state securities
              or "Blue Sky" laws in connection with the Merger. Security will
              provide CitNat and it counsel with a copy of the S

                                      A-8
<PAGE>   141
              -4 Registration Statement for review and comment prior to filing
              with the Securities and Exchange Commission. 

         (d)  All information furnished by one party to another party in
              connection with this Merger Agreement and the transactions
              contemplated hereby will be kept confidential by such other party
              and will be used only in connection with this Merger 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 (except under a claim
              of confidentiality). In the event the Merger Agreement is
              terminated, all such information shall be promptly returned by
              each party to the other party or be destroyed.

         (e)  After: (i) receipt of the Board's prior approval of Security's
              acquisition of CitNat; (ii) the approval of the shareholders of
              CitNat and, if required, Security as provided in Section 10(a) has
              occurred; and (iii) the regulatory waiting period(s) have expired,
              Security shall designate the date as of which Security desires the
              Merger to become effective and shall file the appropriate
              Certificate of Merger with the Ohio Secretary of State in
              accordance herewith and the time the Merger shall become effective
              shall occur at the time and on the date so designated, consistent
              with the terms of Section 4 hereof. However, any date so specified
              shall not be later than either (a) the first day 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 Merger Agreement,
              Security and CitNat each agree that, subject to applicable laws
              and to the fiduciary duties of its 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 Merger Agreement.

         (g)  As soon as practicable following the time the Merger shall become
              effective, employees of Citizens Bank shall be entitled to
              participate in all employee benefit plans of Security. Employee
              benefits of Security will not be changed by this Merger. For
              purposes of eligibility and vesting in Security's employee
              benefits, employees of CitNat and Citizens Bank will be given
              credit for their years of service as employees of CitNat and
              Citizens Bank

         (h)  The CitNat Bancorp, Inc. Employee Stock Ownership Plan and its
              related Trust ("ESOP") shall be terminated or amended at or after
              the effective time of the Merger as directed by Security. If
              terminated, effective as of such termination date each participant
              with an account balance under the ESOP shall become fully vested
              in such account regardless of his vested position under the ESOP.
              CitNat and Security shall cooperate in making any amendments to
              and terminating the ESOP and for making application to the
              Internal Revenue Service for a determination letter to the effect
              that the termination or amendment of the ESOP will not adversely
              affect its tax-qualified status. If terminated, any shares of
              CitNat Common Stocks which are unallocated to participant accounts
              as of the termination date of the ESOP Plan shall be allocated to
              the accounts of participants under the ESOP in such manner as does
              not violate the limitations contained in Section 415 of the Code.
              If terminated, participants'

                                      A-10
<PAGE>   143
              benefits under the ESOP shall be distributed, in connection with
              the termination, in a single lump sum. 

         (i)  Security undertakes to cause, immediately after the effective date
              of the Merger, the election as Directors of Citizens Bank, all
              those persons serving as Directors immediately prior to the
              effective time of the Merger.

         (j)  Security will maintain and make available "current public
              information" within the meaning of Rule 144 for three (3) years
              following the effective date, of the Merger.

         (k)  Security, CitNat, and their respective Directors and Executive
              Officers shall not cause any trades, transfers or other
              transactions in Security Common Stock during the 20 business days
              immediately preceding the effective date of the Merger.

         (l)  Following the effective time of the Merger, with respect to acts
              or omissions occurring prior to the effective time of the Merger,
              Security shall indemnify those persons who were Directors and
              Officers of CitNat immediately prior to the Effective Time, to the
              extent such persons would be entitled to indemnification under the
              Articles of CitNat or as a matter of right under the Ohio General
              Corporation Law, as amended from time to time and Security shall
              indemnify such persons against any liability to the fullest extent
              permitted under Security's Articles of Incorporation or the Ohio
              General Corporation Law.

         (m)  Following the date of this Merger Agreement and until the time the
              Merger shall become effective or until this Merger Agreement shall
              be terminated as provided herein, Security shall provide to
              CitNat, promptly following the filing thereof, all reports, proxy
              statements, registration statements and other information filed
              with the SEC.

11.      Dissenting Shareholders. Holders of CitNat Common Stock shall have the
         rights accorded to dissenting shareholders under Section 1701.85 of the
         Ohio Code, as amended.

12.      Representations and Warranties of Security. Security represents and
         warrants to CitNat as follows:

         (a)  Security is a corporation duly organized and validly existing
              under the laws of the State of Ohio, is a registered bank holding
              company under the Bank Holding Company Act of 1956, as amended,
              and is qualified to do business and is in good standing in the
              State of Ohio, together with all other jurisdictions where it is
              both required to so qualify and the failure to so qualify would
              have material and adverse consequences to Security. Security has
              full power and authority (including all licenses, franchises,
              permits and other governmental authorizations which are legally
              required) to engage in the businesses and activities now conducted
              by it. As of the date of this Agreement, the authorized capital
              stock of Security consisted of 11,000,000 shares of common stock,
              par value $3.125 per share of which a total of 5,107,834 shares
              were issued and outstanding. All of said shares of capital stock
              are fully paid and nonassessable and are not issued in violation
              of the preemptive rights of any shareholder. Security owns all of
              the outstanding capital stock of Security Bank and Dev. Co., and
              Security has no subsidiaries, whether or not wholly-owned, other
              than Security Bank and Dev. Co. Except as disclosed in the letter
              to CitNat of even date herewith, there are not outstanding
              options, warrants or commitments of any kind relating to the issue
              or sale of Security's capital stock.

              The corporate minute books of Security have been made available to
              CitNat and contain, in all material respects, records of all
              meetings and other corporate

                                      A-12
<PAGE>   145
              actions of Security's shareholders, directors and committees of
              directors. Security has delivered to CitNat copies of the articles
              and regulations of Security, including all amendments thereto.
              Security Bank is a national banking association duly organized and
              validly existing under the laws of the United States and has the
              full power and authority, corporate or otherwise, to own its
              property and to carry on its business activities as such
              activities are presently conducted.

         (b)  Security has furnished to CitNat and its counsel copies of the
              following financial statements relating to Security and its
              consolidated subsidiaries: (i) the audited Consolidated Statements
              of Financial Position of Security as of December 31, 1995 and 1994
              and the Consolidated Statements of Income, Shareholders' Equity
              and Statements of Cash Flows for the years then ended, together
              with the notes and report of Ernst & Young, LLP thereto. Each of
              the aforementioned financial statements is true and correct in all
              material respects and together present fairly the consolidated
              financial position and results of operations of Security as of the
              dates and for the periods therein set forth in conformity with
              generally accepted accounting principles ("GAAP"). Such financial
              statements do not, as of the dates thereof, include any material
              asset or omit any material liability, 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, 1995, there has not been any material adverse change in the
              financial condition, results of operations, business or prospects
              of Security and its subsidiaries on a consolidated basis.

         (c)  The Board of Directors of Security has authorized execution of
              this Merger Agreement and approved the merger of CitNat and
              Security as contemplated by said Merger Agreement. Security has
              all requisite power and authority to enter 

                                      A-13

<PAGE>   146
              into this Merger Agreement and Security has the authority to
              consummate the transactions contemplated hereby. This Merger
              Agreement constitutes the valid and legally binding obligation of
              Security and this Merger Agreement and the consummation hereof has
              been duly authorized and approved on behalf of Security by all
              requisite corporate action. Provided the required approvals are
              obtained from the Board, neither the execution and delivery of
              this 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 Security may be subject, any contract, agreement
              or instrument to which Security is a party or by which Security is
              bound or committed, or the Articles of Incorporation or Code of
              Regulations of Security or the Articles of Association or Bylaws
              of Security Bank, or constitute an event which, including with the
              lapse of time or action by a third party, could, to the best of
              Security's knowledge, result in the default under any of the
              foregoing or result in the creation of any lien, charge or
              encumbrance upon any of the assets or properties of Security or
              any of its subsidiaries or upon any of the stock of Security or
              any of its subsidiaries, 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, in the aggregate, have any material adverse
              effect on the financial condition, results of operations or
              business of Security on a consolidated basis.

         (d)  There is no litigation, action, suit, investigation or proceeding
              pending or, to the best of the knowledge after due inquiry of
              Security and its executive officers, 

                                      A-14

<PAGE>   147
              threatened, against Security or its subsidiaries or involving any
              of 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 Security or its subsidiaries, would
              materially affect the financial condition or operations of
              Security or its subsidiaries on a consolidated basis and/or
              Security's ability to perform under this Merger Agreement, and to
              the best of the knowledge and belief after due inquiry of Security
              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 Security or its
              subsidiaries based upon the wrongful action or inaction of
              Security or its 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 shareholders of CitNat surrender
              their CitNat share certificates for cancellation and the CitNat
              Option holders deliver documents evidencing the surrender and
              cancellation of their CitNat Options, the shares of Security
              Common Stock to be received therefore will have been duly
              authorized and validly issued by Security and will be fully paid
              and nonassessable and be issued free of preemptive rights.

         (f)  Security has not incurred and will not incur directly or
              indirectly any liability for brokerage, finders', agents' or
              investment bankers' fees or commissions in connection with this
              Merger Agreement or the transactions contemplated thereby.

         (g)  The Security National Bank & Trust Company 401K Profit Sharing and
              Savings Plan (the "Profit Plan") and The Security National Bank &
              Trust Company Pension Plan and Trust (the "Pension Plan")
              (hereinafter referred to collectively as the "plans") which
              purport to be qualified plans under Section 401(a) of the Internal
              Revenue Code of 1986, as amended, ("Code") are so qualified and
              are in 

                                      A-15

<PAGE>   148
              compliance in all material respects with the applicable
              requirements of the Employee Retirement Income Security Act of
              1974, as amended ("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 could result
              in a penalty or result in disqualification of the plan. Security
              has no knowledge either of any circumstances which would adversely
              affect the qualification 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 Code) which has occurred, or
              to the best knowledge of Security is likely to occur, with respect
              to either plan since the date on which said sections became
              applicable to the plans. The plans meet any minimum funding
              standards set forth in the Code and ERISA which are applicable to
              them.

         (h)  Security has timely filed all reports and registration statements
              (collectively, "SEC Documents") required to be filed by it
              pursuant to the Securities Act of 1933, as amended, and the
              Securities Exchange Act of 1934, as amended, for periods ending
              after January 1, 1992, and such SEC Documents complied in all
              material respects with the Securities Act of 1933 and the
              Securities Exchange Act of 1934 and all applicable rules and
              regulations promulgated thereunder (the "SEC Laws"). Security has
              delivered to CitNat copies of the Annual Report on Form 10-K filed
              with the Securities and Exchange Commission by Security for its
              fiscal year ended December 31, 1994, including exhibits and all
              documents incorporated by reference therein, and the proxy
              materials disseminated by Security to its shareholders in
              connection with the 1995 Annual Meeting of Shareholders of
              Security; such Annual Report and proxy materials and the SEC
              Documents 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, 1995: (i) each of Security and its subsidiaries
              has conducted business only in the ordinary course, and has
              preserved its corporate existence, business and goodwill intact;
              (ii) there has been no material adverse change in the assets,
              liabilities, business or operations of Security or its
              subsidiaries; and (iii) there has been no damage, destruction,
              loss, or event whether or not insured against) which in the
              aggregate has had or might reasonably by expected to have a
              material adverse effect on the business or operations of Security
              or any of its subsidiaries.

         (j)  Security and Security Bank each have good and marketable title to
              all assets and properties, whether real or personal, tangible or
              intangible, including without limitation the capital stock of
              Security Bank and all other assets and properties reflected in
              Security's Balance Sheet of December 31, 1995 or acquired
              subsequent thereto (except to the extent that such assets and
              properties have been disposed of for fair value in the ordinary
              course of business since December 31, 1995) 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; (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; (iv) pledges or
              liens required to be granted in connection with the acceptance of
              government deposits or granted in connection with repurchase
              agreements; and (v) easements, encumbrances, liens, mortgages and
              security interests of record which do not impair the use thereof
              for the purposes intended and such liens, mortgages,

                                      A-17
<PAGE>   150
              security interests, encumbrances and charges are not, in the
              aggregate, material to the assets and properties of Security.
              Security or Security Bank as lessee has the contractual right
              under valid leases to occupy, use, possess and control all
              property leased by Security or Security Bank which is material to
              their operations. 

         (k)  To the best of the knowledge after due inquiry of Security and its
              executive officers, Security and Security Bank have complied with
              all laws, regulations and orders applicable to Security and
              Security Bank and to the conduct of their businesses, including
              without limitation, all statutes, rules and regulations pertaining
              to the conduct of banking activities except for possible technical
              violations which together with any penalty which results therefrom
              do not or will not have a material adverse effect on the financial
              condition, results of operations or business of Security and
              Security Bank on a consolidated basis. Neither Security nor
              Security Bank 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 Security's 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 Security and Security Bank on a consolidated basis.

         (l)  Security has duly and timely 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 Security up to the date
              hereof. To the best of the knowledge and belief of Security all
              such returns are true and correct in all material respects, and
              Security has paid or, prior to the time the 

                                      A-18

<PAGE>   151
              Merger shall become effective, will pay all taxes, interest and
              penalties shown on such return or reports or claimed (other than
              those claims being contested in good faith and which have been
              disclosed to CitNat) 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
              Security or Security Bank, and for which an adequate reserve has
              not been established. To the best of its knowledge and belief,
              Security 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 Security 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 Security as of the time the
              Merger shall become effective.

         (m)  The deposits of Security Bank are insured by the Federal Deposit
              Insurance Corporation and Security Bank has paid all premiums and
              assessments with respect to such deposit insurance.

         (n)  Security has no knowledge of any hazardous substances, hazardous
              waste, pollutant or contaminant, including, but not limited to,
              asbestos (except as previously disclosed to CitNat in a letter of
              even date herewith), PCB's or urea formaldehyde, having been
              generated, released into, stored or deposited over, upon or below
              (in storage tanks or otherwise) the premises of Security or
              Security Bank or any other real property owned or leased by
              Security or Security Bank, or into any water systems on or below
              the surface of Security or Security Bank premises or any other
              real property owned or leased by Security or Security Bank

              in violation of any law, regulation or requirement or in any
              manner which could result in a material adverse impact on the
              value of the premises or property or present a threat to human
              health or the environment. As used in this Merger 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. 

         (o)  Security and Security Bank have in effect insurance coverage with
              reputable insurers, which in respect of amounts, premiums, types
              and risks insured, constitutes reasonably adequate coverage
              against all risks customarily insured against by companies
              comparable in size and operation to Security or Security Bank.

13.      Representations and Warranties of CitNat. CitNat represents and
         warrants to Security as follows:

         (a)  CitNat is a corporation duly organized and validly existing under
              the laws of the State of Ohio, and is a registered bank holding
              company under the Bank Holding Company Act of 1956, as amended.
              CitNat has full power and authority (including all licenses,
              franchises, permits and other governmental authorizations which
              are legally required which, if not obtained or possessed, would
              have a materially adverse effect on the business and operations of
              CitNat) to engage in the businesses and activities now conducted
              by it. As of the date of this Merger Agreement, the authorized
              capital stock of CitNat consists of 720,000 shares of common stock
              with $5 par value per share, of which a total of 390,119 shares
              are issued and outstanding, 2,482 shares are held as treasury
              shares and options have been granted to purchase 71,820 shares of
              CitNat Common Stock. All of said shares of capital stock are fully
              paid and nonassessable and were not issued in violation of the
              preemptive rights of any shareholder. There are no outstanding

                                      A-20
<PAGE>   153
              options, warrants or commitments of any kind relating to CitNat's
              authorized but unissued capital stock except the CitNat Options
              disclosed in the letter to Security of even date herewith.

         (b)  CitNat has furnished to Security copies of the following financial
              statements relating to CitNat and its consolidated subsidiaries:
              (i) the audited Consolidated Balance Sheets of CitNat as of
              December 31, 1995 and 1994 and the Consolidated Statements of
              Income, Changes in Shareholders' Equity and Statements of Cash
              Flows for the years then ended, together with the notes and report
              of Crowe, Chizek and Company, LLP thereto, (ii) copies of all
              reports of CitNat and Citizens Bank as filed with the appropriate
              regulatory agencies, as of and for the years ended December 31,
              1995 and 1994. Each of the aforementioned financial statements is
              true and correct in all material respects and together present
              fairly in all material respects the consolidated financial
              position and results of operations of CitNat as of the dates and
              for the periods therein set forth in conformity with GAAP. Such
              financial statements do not, as of the dates thereof, include any
              material asset or omit any material liability, absolute or
              contingent, or other fact, required to be included or omitted as
              the case may be, by GAAP. Since December 31, 1995, there has not
              been any material adverse change in the financial condition,
              results of operations, or business of CitNat and Citizens Bank on
              a consolidated basis.

         (c)  The Board of Directors of CitNat has authorized execution of this
              Merger Agreement. Subject to the approval by the shareholders of
              CitNat, CitNat has all requisite power and authority to enter in
              this Merger Agreement. CitNat owns all of the shares of Citizens
              Bank and CitNat has the authority to consummate the transactions
              contemplated hereby so that, provided all required corporate and
              regulatory approvals are obtained and all conditions to CitNat's
              obligations as set 

                                      A-21

<PAGE>   154
              forth in this Merger Agreement are satisfied, neither the
              execution and delivery of this 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 CitNat may be subject, any contract, agreement or
              instrument to which CitNat is a party or by which CitNat is bound
              or committed, or the Articles of Incorporation or Code of
              Regulations of CitNat, or constitute an event which with the lapse
              of time or action by a third party, could, to the best of CitNat'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 CitNat, 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, in the aggregate, have any
              material adverse effect on the financial condition, results of
              operations or business of CitNat and Citizens Bank on a
              consolidated basis.

         (d)  There is no litigation, action, suit, investigation or proceeding
              pending or, to the best of their knowledge after due inquiry of
              CitNat and its executive officers, overtly threatened, against
              CitNat or Citizens Bank or involving any of 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
              CitNat or Citizens Bank would materially affect the financial
              condition or operations of CitNat and Citizens Bank on a
              consolidated basis and/or CitNat's ability to perform under this
              Merger Agreement. To the best knowledge after due inquiry of
              CitNat and its executive 

                                      A-22
<PAGE>   155
                  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 CitNat or Citizens
                  Bank or be based upon the wrongful action or inaction of
                  CitNat or Citizens Bank or any of their respective officers,
                  directors or employees.

         (e)      CitNat and Citizens Bank have good and marketable title to all
                  assets and properties, whether real or personal, tangible or
                  intangible, including without limitation the capital stock of
                  Citizens Bank, reflected in CitNat's Balance Sheet of December
                  31, 1995 or acquired subsequent thereto (except to the extent
                  that such assets and properties have been disposed of for fair
                  value in the ordinary course of business since December 31,
                  1995) 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; (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; (iv) pledges
                  or liens required to be granted in connection with the
                  acceptance of government deposits or granted in connection
                  with repurchase agreements; and (v) easements, encumbrances,
                  liens, mortgages and security interests of record which do not
                  impair the use thereof for the purposes intended and such
                  liens, mortgages, security interests, encumbrances and charges
                  are not in the aggregate, material to the assets and
                  properties of CitNat. CitNat or Citizens Bank have as lessee
                  the contractual right under valid leases to occupy, use,
                  possess and control all material property leased by CitNat or
                  Citizens Bank.

         (f)      To the best of the knowledge after due inquiry of CitNat and
                  its executive officers, CitNat and Citizens Bank have complied
                  with all laws, regulations and orders applicable to CitNat and
                  Citizens Bank and to the conduct of their

                                      A-23
<PAGE>   156
                  businesses, including without limitation, all statutes, rules
                  and regulations pertaining to the conduct of banking
                  activities except for possible technical violations which
                  together with any penalty which results therefrom do not or
                  will not have a material adverse effect on the financial
                  condition, results of operations or business of CitNat and
                  Citizens Bank on a consolidated basis. Neither CitNat nor
                  Citizens Bank 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 CitNat's 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 CitNat and
                  Citizens Bank on a consolidated basis.

         (g)      Except as disclosed in CitNat's letter to Security of even
                  date herewith, receipt of which is acknowledged by Security,
                  CitNat and Citizens Bank have not, since December 31, 1995 to
                  the date hereof: (i) issued or sold any of its capital stock
                  or any issued any corporate debt securities other than in the
                  ordinary course of its banking business; (ii) granted any
                  option for the purchase of capital stock; (iii) declared or
                  set aside or paid any dividend or other distribution in
                  respect of its capital stock except as permitted pursuant to
                  Section 15(a) hereof or, directly or indirectly, purchased,
                  redeemed or otherwise acquired any shares of such stock; (iv)
                  incurred any obligation or liability (absolute or contingent),
                  except for obligations reflected in this Merger Agreement, and
                  except for obligations or liabilities incurred in the ordinary

                  liabilities which become due after December 31, 1995,
                  business, liabilities incurred in carrying out the
                  transactions contemplated by this Merger Agreement and
                  obligations and liabilities paid in the ordinary course of
                  business; (vi) sold, exchanged or otherwise disposed of any of

         (h)      Except as set forth in the CitNat Document List attached to
                  CitNat's letter to Security of even date herewith, receipt of
                  which is acknowledged by Security, neither CitNat nor Citizens
                  Bank is a party to or bound by any written or, to the best of
                  its knowledge after due inquiry, oral: (i) employment or
                  consulting contract which is not terminable by CitNat or
                  Citizens Bank on 60 days or less notice, (ii) employee bonus,

                  employee benefit or welfare plan, or (iv) other executory
                  material agreements which in any case obligate CitNat or
                  Citizens Bank to make any payment(s) which in the

<PAGE>   158
                  aggregate exceed $25,000 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
                  CitNat Document List (hereinafter referred to collectively as
                  the "plans") 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 could
                  result in a penalty of $25,000 and/or result in
                  disqualification of the plan. CitNat 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, except as indicated in the
                  CitNat Document List attached to CitNat's letter to Security
                  of even date herewith, 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. No such
                  plan is subject to the minimum funding standards set forth in
                  the Code and ERISA.

         (i)      CitNat 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 CitNat up to the
                  date hereof. Except as set forth in CitNat's letter to
                  Security of even date herewith, receipt of which is
                  acknowledged by Security, to the best of the knowledge and
                  belief of CitNat all such returns are true and correct in all
                  material respects, and CitNat has paid or, prior to the time
                  the Merger shall become effective, will pay all taxes,
                  interest and

                                      A-26
<PAGE>   159
                  penalties shown on such return or reports or claimed (other
                  than those claims being contested in good faith and which have
                  been disclosed to Security) 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 CitNat or Citizens Bank and for which an
                  adequate reserve has not been established. To the best of its
                  knowledge and belief, CitNat 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,
                  CitNat 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 CitNat as of the time the Merger shall
                  become effective.

         (j)      CitNat has no knowledge of any hazardous substances, hazardous
                  waste, pollutant or contaminant, including, but not limited
                  to, asbestos (except as previously disclosed to Security in a
                  letter of even date herewith), PCB's or urea formaldehyde,
                  having been generated, released into, stored or deposited
                  over, upon or below (in storage tanks or otherwise) the
                  Citizens Bank premises or any other real property owned or
                  leased by CitNat or Citizens Bank, or into any water systems
                  on or below the surface of the Citizens Bank premises or any
                  other real property owned or leased by CitNat or the Citizens
                  Bank in violation of any law, regulation or requirement or in
                  any manner which could result in a material adverse impact on
                  the value of the premises or property or present a threat to
                  human health or the environment. As used in this Merger
                  Agreement, the terms "hazardous substance," "hazardous waste,
                  "pollutant" and "contaminant" mean

                                      A-27
<PAGE>   160
                  any substance, waste, pollutant or contaminant included within
                  such terms under any applicable Federal, state or local
                  statute or regulation.

         (k)      CitNat or Citizens Bank has in effect insurance coverage with
                  reputable insurers, which in respect of amounts, premiums,
                  types and risks insured, constitutes reasonably adequate
                  coverage against all risks customarily insured against by
                  companies comparable in size and operation to CitNat or
                  Citizens Bank.

         (l)      Other than as previously disclosed to Security, in writing,
                  with respect to the fairness opinion relating to the Merger
                  and other than professional fees and disbursements of its
                  accountants and attorneys, CitNat has not incurred and will
                  not incur any liability for brokerage, finders', agents', or
                  investment bankers' fees or commissions in connection with
                  this Merger Agreement or the transactions contemplated hereby.

14.      Action by CitNat Pending Effective Time. CitNat agrees that from the
         date of this Merger Agreement until the time the Merger shall become
         effective, or until this Merger Agreement is terminated as provided for
         herein, except with prior written permission of Security:

         (a)      Beginning with the date hereof and until such time as the
                  Merger shall become effective, CitNat will not declare or pay
                  any dividends or make any distributions other than a cash
                  dividend at the rate of $0.45 per share payable in July 1996,
                  and, in the event the Merger shall not have consummated and
                  holders of CitNat Common Stock shall not have become holders
                  of Security Common Stock prior to the record date for the
                  determination of Security stockholders entitled to receive
                  Security's cash dividend normally paid in December of each
                  year, then a cash dividend at the rate $0.45 per share payable
                  in December, 1996. If, prior to the consummation of the
                  Merger, CitNat shall declare a stock dividend or make
                  distributions upon or subdivide, split up, reclassify or
                  combine its shares of

                                      A-28
<PAGE>   161
                  common stock in any security convertible into its common
                  stock, appropriate adjustment or adjustments will be made in
                  the foregoing dividend ratio.

         (b)      CitNat 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 for the closing and disposition of the Southtown branch
                  and as otherwise set forth in or contemplated by this Merger
                  Agreement, CitNat and Citizens Bank will carry on their
                  respective businesses in substantially the same manner as on
                  the date hereof, 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)      CitNat and Citizens Bank 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 Citizens Bank's
                  lending, investment, liability management and other material
                  banking policies in any material 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 (which in no event shall include the establishment of
                  new branches and such other facilities) or any capital
                  expenditures for any purpose which exceed $170,000, or (v)
                  except as provided in Section 9 hereof, 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; except for the closing and disposition
                  of the Southtown branch.

                                      A-29
<PAGE>   162
         (e)      CitNat will not change its or Citizens Bank's methods of
                  accounting in effect at December 31, 1995 except as required
                  by changes in generally accepted accounting principles and
                  concurred in by CitNat'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
                  CitNat's Federal income tax returns for the taxable year
                  ending December 31, 1995, except for changes required by law.

         (f)      CitNat will afford Security, its officers and other authorized
                  representatives, subject to the confidentiality requirements
                  of Section 10(d) hereof, such access to all books, records,
                  tax returns, leases, contracts and documents of CitNat or
                  Citizens Bank and will furnish to Security such information
                  with respect to the assets and business of CitNat and Citizens
                  Bank as Security may from time to time reasonably request in
                  connection with this Merger Agreement and the transactions
                  contemplated hereby.

         (g)      CitNat will promptly furnish Security with copies of all
                  interim financial statements of CitNat as they become
                  available, and keep Security fully informed concerning all
                  developments which in the opinion of CitNat may have a
                  material effect upon the business, properties or condition
                  (either financial or otherwise) of CitNat.

15.      Action by Security Pending Effective Time. Security agrees that from
         the date of this Agreement until the time the Merger shall become
         effective or until this Merger Agreement is terminated as provided for
         herein:

         (a)      Security will carry on its business in substantially the same
                  manner as heretofore except as otherwise set forth in or
                  contemplated by this Merger Agreement, and Security will 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

                                      A-30
<PAGE>   163
                  and preserve its business organization intact. CitNat
                  acknowledges that, in the ordinary course of its business as a
                  bank holding company, Security from time-to-time, enters into
                  an agreement(s) to acquire by merger, stock purchase or like
                  means, another financial institution or its holding company.

         (b)      Security will not change its methods of accounting in effect
                  at December 31, 1995, except as required by changes in
                  generally accepted accounting principles as concurred in by
                  Security'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 the Federal
                  income tax returns of Security Bank for the taxable year
                  ending December 31, 1995, 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)      Security will promptly furnish CitNat with copies of press
                  releases, interim financial statements of Security and all
                  reports, schedules and statements filed by or delivered to
                  Security pursuant to the Securities and Exchange Act of 1934
                  and the rules and regulations promulgated thereunder, as they
                  become available.

         (d)      Security will afford CitNat, its officers and other authorized
                  representatives, subject to the confidentiality requirements
                  of Section 10(d) hereof, such access to all books, records,
                  tax returns, leases, contracts and documents of Security and
                  will furnish to CitNat such information with respect to the
                  assets and business of Security as CitNat may from time to
                  time reasonably request in connection with this Merger
                  Agreement and the transactions contemplated hereby.

16.      Conditions to Obligations of Security. The obligations of Security
         under this Merger Agreement are subject, unless waived by Security, to
         the satisfaction of the following conditions on or prior to the time
         the Merger shall become effective:

                                      A-31
<PAGE>   164
         (a)      There shall not have been any material adverse change or
                  discovery of a condition or the occurrence of an event (other
                  than events similarly affecting all financial institutions)
                  which has or is likely to result in such a material adverse
                  change, in the financial condition, aggregate net assets,
                  shareholders' equity, business or operating results of CitNat
                  on a consolidated basis from December 31, 1995 to the time the
                  Merger shall become effective.

         (b)      CitNat shall not have paid cash dividends from the date hereof
                  to the time the Merger shall become effective, except as
                  permitted under this Merger Agreement.

         (c)      All representations by CitNat contained in this Merger
                  Agreement shall be true in all material respects at, or as of,
                  the time the Merger shall become effective as though such

                  changes contemplated by the Merger Agreement and except also
                  for representations as of a specified time other than the time

                  phase I environmental audit of any real property owned by

                  discovered which if known by CitNat as of the date of this
                  Agreement would have violated the representation contained in

                  being successfully prosecuted and (ii) if successfully
                  prosecuted, would materially and adversely affect the
                  financial condition, results of operations or shareholders'

                  and its subsidiaries as CitNat shall have deemed prudent, and
                  such review and examination shall not have disclosed matters
                  which are inconsistent in any material respect with any of the
                  representations and warranties of Security contained in this

         and their respective successors and permitted assigns, but neither this
         Merger Agreement nor any of the rights, interests, or obligations
         hereunder shall be assigned by either of the parties hereto without the
         prior written consent of the other party.

22.      Satisfaction of Conditions; Termination.

         (a)      Security agrees to use its best effort to obtain satisfaction
                  of the conditions insofar as they relate to Security, and
                  CitNat agrees to use its best efforts to obtain the
                  satisfaction of the conditions insofar as they relate to
                  CitNat. If any condition to the obligations of Security set
                  forth in Section 16 or 18 is not substantially satisfied at
                  the time or times contemplated thereby and such condition is
                  not waived by Security, or if any condition to the obligations
                  of CitNat set forth in Section 17 or 18 is not substantially
                  satisfied at the time or times contemplated thereby and such
                  condition is not waived by CitNat, or if at any time prior to
                  the time the Merger shall become effective, it shall become
                  reasonably certain that such condition will not be
                  substantially satisfied and such condition is not waived by
                  Security or CitNat, as the case may be, either Security or
                  CitNat may terminate this Merger Agreement by written notice
                  to the other party after the expiration of fifteen (15) days
                  written notice to the other party during which time such other
                  party shall have an opportunity to cure such defect in said
                  condition. This Merger Agreement may be terminated and
                  abandoned (either before or after the meetings of shareholders
                  contemplated hereby) by mutual written consent of Security and

                  the event of such termination caused otherwise than by breach
                  of this Merger Agreement by any of the parties hereto, this
                  Merger Agreement shall cease and terminate, the acquisition of
                  CitNat as provided herein shall not be consummated, and
                  neither Security nor CitNat shall have any further liability
                  under this Merger Agreement of any nature whatever, including
                  any liability for damages. In the event this Merger Agreement
                  is terminated, the duties of both parties with respect to
                  confidential information set forth in Sections 10(d) shall
                  survive any such termination. In addition to the other grounds
                  for termination of this Merger Agreement set forth herein,
                  this Merger Agreement can be terminated by written notice by
                  either party to the other, in each case authorized by its
                  Board of Directors, if the Merger shall not have been
                  consummated by December 31, 1996 or the date of such notice,
                  whichever is later.

         (b)      If termination of this Merger Agreement shall be judicially
                  determined to have been caused by breach of this Merger
                  Agreement, then, in addition to other remedies at law or
                  equity for breach of this Merger Agreement, the party so found
                  to have breached this Merger Agreement shall indemnify the
                  other parties for their respective costs, fees and expenses of
                  its counsel, accountants and other experts and advisors as
                  well as fees and expenses incident to negotiation, preparation
                  and execution of this Merger Agreement and related actions and
                  its shareholders' meetings and actions.

         (c)      In the event of the failure of the CitNat shareholders to
                  approve the Merger and this Agreement, provided at the time of
                  the CitNat shareholders' meeting to vote upon the Merger
                  either (a) there is outstanding a publicly announced offer by
                  a third-party to acquire CitNat, by merger consolidation,
                  exchange offer or asset purchase, or a tender offer for at
                  least fifty-one percent (51%) of the outstanding

                                      A-40

                  CitNat common stock in either case providing a per share
                  purchase valued at the time of its announcement of at least
                  $62.75 per share to the CitNat shareholders, or (b) the Board
                  of Directors of CitNat fails to favorably recommend approval
                  of the Merger, then in any such event, CitNat shall pay One
                  Million Dollars ($1,000,000) to Security as an agreed upon
                  termination fee upon the occurrence of either of the following
                  events within one (1) year after termination of this
                  Agreement:

                                    Security and/or its affiliates) shall
                                    acquire more than fifty percent (50%) of the
                                    outstanding CitNat common stock at a per
                                    share price equal to or greater than $62.75;
                                    or

                           (ii)     upon the entry by CitNat into a definitive
                                    agreement with a person or group of persons
                                    (other than Security and/or its affiliates)
                                    for such person or group of persons to
                                    acquire, merge or consolidate with CitNat or
                                    to acquire all or substantially all of
                                    CitNat's assets and wherein the per share
                                    purchase price at the time of the initial
                                    public announcement thereof equals or
                                    exceeds $62.75; except for such transaction
                                    in which the shareholders of CitNat
                                    immediately prior to the transaction control
                                    a majority of the voting stock of the
                                    resulting entity of such transaction.

         be waived at any time by the party which is, or the shareholders of
         which are, entitled to the benefit thereof, by such party. This Merger
         Agreement may be amended or modified in whole or in part by an
         agreement in writing executed in the same manner (but not necessarily
         by the same person) as this Merger Agreement and which makes reference
         to this Merger Agreement, pursuant to a resolution, adopted by the
         Boards of Directors of the respective

                                      A-41
<PAGE>   174
         parties, provided, however, such amendment or modification may be made
         in this manner by the respective Boards of Directors of Security and
         CitNat at any time prior to a favorable vote of such party's
         shareholders, but may be made after a favorable vote by the
         shareholders of such party, only if, in the opinion of its Board of
         Directors, such amendment or modification will not have any material
         adverse effect on the benefits intended under this Merger Agreement for
         the shareholders of such party and will not require resolicitation of
         any proxies from such shareholders or further shareholder approval is
         obtained.

24.      Entire Agreement. This Agreement supersedes any other agreement,
         whether written or oral, that may have been made or entered into by
         Security and CitNat or by any officer or officers of such parties
         relating to the acquisition of the business or the capital stock of

27.      Undertakings of Affiliates. Security shall have received undertakings

Security Banc Corporation
40 S. Limestone St.
Springfield, OH  45502-1222

Ladies and Gentlemen:

         We have acted as special counsel to CitNat Bancorp, Inc. ("CitNat"), an
Ohio corporation and bank holding company, solely in connection with certain
transactions contemplated by the Agreement of Merger (the "Agreement of
Merger"), dated March __, 1996, by and between CitNat and Security Banc
Corporation ("Security"), an Ohio corporation and bank holding company.

         This opinion is furnished to you pursuant to Section __ of the Merger
Agreement.

         In connection with this opinion, we have examined the following:

         (a)   The Merger Agreement;

         (b)   The Articles of Incorporation of CitNat, with amendments thereto,
               as certified by the Ohio Secretary of State on _______, 1996 (the
               "CitNat Articles");

         (c)   The Code of Regulations of CitNat, as certified by the Secretary
               of CitNat on _________, 1996 (the "CitNat Regulations");

         (d)   A Certificate from the Ohio Department of Taxation dated
               ________, 1996, with respect to the payment of all taxes by
               CitNat;

         (e)   A Certificate from the Ohio Secretary of State dated ________,
               1996, with respect to the good standing of CitNat;

         (f)   The Articles of Association of The Citizens National Bank of
               Urbana (the "Citizens Bank"), with amendments thereto, as
               certified by the Secretary of the Citizens Bank on _________,
               1996 (the "Bank Articles");

                                      A-45
<PAGE>   178
         (g)   The Bylaws of the Citizens Bank, as certified by the Secretary of
               the Citizens Bank on _________, 1996 (the "Bank Bylaws");

         (h)   Selected minutes of the Boards of Directors and the shareholders
               of CitNat and the Citizens Bank and other corporate records of
               CitNat and the Citizens Bank as in our judgment are necessary or
               appropriate to enable us to render the opinions expressed below;

         (i)   The S-4 Registration Statement and the proxy materials of the
               Citizens Bank included therein and relating to the special
               meeting of the shareholders of the Citizens Bank held for the
               purpose of adopting the Agreement of Merger; and

         (j)   The Certificates of certain officers of CitNat and the Citizens
               Bank (the "Officers' Certificates").

         Unless otherwise defined herein, all capitalized terms used in this
opinion have the meanings set forth in the Merger Agreement.

         In our examinations, we have assumed, without independent investigation
or verification, the following:

         (a)   that all documents, forms or drafts submitted to us as copies
               (whether or not certified) conform to the originals of these
               documents, and the originals of such documents are authentic; and
               all signatures of all persons are genuine; and

         (b)   the due authorization, execution and delivery of all documents by
               Security and the taking by Security of all appropriate action
               required by and related to the transactions contemplated by the
               Merger Agreement.

         Whenever any matter is indicated to be based on our knowledge, we are
referring to the actual knowledge of the Vorys, Sater, Seymour and Pease
attorneys who have represented CitNat in connection with the matters recited in
the first paragraph of this opinion on page 1. We have relied solely on the
examinations and inquiries recited in this opinion, and we have not undertaken
any other independent investigation to determine the existence or absence of any
facts, and no inference as to our knowledge concerning such facts should be
drawn. As used herein, the phrases "corporate power and authority," "duly
authorized by all necessary corporate action," and "by all necessary shareholder
action" refer and are limited to Chapter 1701, Ohio Revised Code, (the Ohio
General Corporation Law) and the CitNat Articles and CitNat Regulations.

         Based on and subject to the foregoing and the further qualifications
and limitations described below, as of the date of this opinion (or as of the
date of any assumption made or any certificate, schedule, exhibit, or inquiry
stated to have been examined, made or otherwise relied upon by us), we are of
the opinion that:

                                      A-46
<PAGE>   179
         1. CitNat is a corporation validly existing and in good standing under
the laws of the State of Ohio with full corporate power and authority to own its

         2. CitNat's authorized capital stock consists of 720,000 common shares
(the "CitNat Common Stock"), par value $5.00 per share, of which 390,119 shares
are issued and outstanding and 2,482 shares are held as treasury shares.

         3. Options to purchase 71,820 shares of CitNat Common Stock (the
"CitNat Options") are outstanding. To our knowledge, there are not any
outstanding subscriptions, warrants, options, rights, commitments or agreement
by which CitNat is bound which provide for the issuance of CitNat Common Stock
or for the issuance of any securities convertible into CitNat Common Stock,
except as disclosed above.

         4. The Citizens Bank is a national banking association validly existing
under the laws of the United States with full corporate power and authority to
own its properties and to carry on its business as now conducted.

         5. CitNat is the record owner of all the capital stock of the Citizens
Bank.

         6. CitNat has all requisite corporate power and authority to enter into
and perform all of its obligations under the Merger Agreement. The execution and
delivery of the Merger Agreement and the performance by CitNat of its
obligations under the Merger Agreement have been duly authorized by all
necessary corporate action by CitNat and by all necessary shareholder action.

         7. The Merger Agreement is the valid and binding obligation of CitNat,
enforceable against it in accordance with its terms.

         8. CitNat is not, and will not be by execution and delivery of the
Merger Agreement or by the performance of its obligations under the Merger
Agreement, in violation of any (a) material term or provision of the CitNat
Articles or the CitNat Regulations; or (b) material agreement to which CitNat or
the Citizens Bank is a party and which is known to us.

         9. Based solely upon the Officers' Certificates, we have no knowledge
of any: (a) material actions, suits or proceedings instituted, pending or
threatened against CitNat or the Citizens Bank or against any material asset,
interest or right of CitNat or the Citizens Bank; and (b) actual or threatened
actions, suits or proceedings against CitNat which present a claim to restrain
or prohibit CitNat's performance of its obligations under the Merger Agreement.

         The opinions expressed above are subject to the following additional
qualifications:

         We have not conducted requisite factual or legal examinations and
accordingly we express no opinion with respect to the application, if any, of
laws concerning or promulgated by (a) environmental effects or agencies; (b)
securities laws; (c) any order of any court or other



                                      A-47
<PAGE>   180
authority directed specifically to any party to the Merger Agreement of which we
do not have knowledge; and (d) any taxes or tax effects.

         All of our opinions herein are subject to the limitations, if any, of
Title 11, U.S.C., as amended, and of any applicable insolvency, reorganization,
moratorium or other laws affecting creditors' rights generally and by principles
of equity. In addition, certain remedial and other provisions of the Merger
Agreement may be limited by (a) implied covenants of good faith, fair dealing
and commercially reasonable conduct; (b) judicial discretion, in the instance of
equitable remedies; and (c) the public policies of the State of Ohio, to the

         This opinion is limited to the laws of Ohio and the federal laws of the

Re:  Security Banc Corporation.

Gentlemen:

We have acted as special counsel to Security Banc Corporation ("Security") an
Ohio corporation, in connection with the contemplated Merger Agreement dated
______, 1996 (the "Agreement") between CitNat Bancorp, Inc. ("CitNat") and
Security. This Opinion Letter is rendered to you pursuant to Section _____ of
the Agreement. Capitalized terms not otherwise defined herein shall have the
meanings ascribed to them in the Agreement.

You have requested our opinion regarding certain matters in connection with the
Agreement. In our capacity as special counsel for Security and Security Bank, we
have examined the originals or copies of such certificates, documents and
corporate records upon which we have relied regarding our opinion expressed
below. We have assumed the genuineness of all signatures, the authenticity of
all items submitted to us as certified or photostatic copies and the
authenticity of the originals of such copies. We have further assumed the due
authorization of such documents by all parties other than Security and Security
Bank and the taking of all requisite action respecting such documents, the due
execution and delivery of such documents by each party and have additionally
assumed that all agreements are the valid and binding agreement of all parties
to such agreements, other than Security and Security Bank.

Wherever a statement herein is qualified by "to the best of our knowledge," or a
similar phrase, it is intended to indicate that, during the course of our
representation of Security and Security Bank, no information has been provided
to those partners and associates in this firm who have had substantive
involvement in rendering legal services in connection with the representation
described in the introductory paragraph of this opinion letter that would give
us knowledge of the inaccuracy of such statement.

This Opinion Letter is governed by, and shall be interpreted in accordance with,
the Legal Opinion Accord (the "Accord") of the ABA Section of Business Law
(1991). As a consequence, it is subject to a number of qualifications,
exceptions, definitions, limitations on coverage and other limitations, all as
more particularly described in the Accord, and this Opinion Letter should be

The opinions hereinafter expressed are subject to the following qualifications,
notwithstanding anything herein to the contrary:

<PAGE>   182
         (a) Our opinions in paragraphs (1) and (4) below as to the valid
existence of Security and Security Bank are based solely upon certificates from
public officials as to valid existence, copies of which certificates are
attached hereto.

         (b) Our opinions below are limited to the matters expressly set forth
in this opinion letter, and no opinion is to be implied or may be inferred
beyond the matters expressly so stated. Without limiting the foregoing, we
express no opinion as to the antifraud provisions of federal and state
securities laws.

         (c) We disclaim any obligation to update this opinion letter for events
occurring after the date of this opinion letter.

         (d) Our opinions below are limited to the effect of the laws of Ohio
and the federal laws of the United States of America. We express no opinion with
respect to the effect of the laws of any other jurisdiction on the transactions
contemplated by the Agreement.

         (e) In rendering this opinion, we have relied as to all matters of fact
on certificates or responsible officers of Security and Security Bank and of
public officials, copies of which are attached hereto.

         Based upon and subject to the foregoing and in reliance thereon, and
subject to the assumptions, exceptions and qualifications set forth herein, it
is our opinion that:

1. Security is a corporation validly existing and in good standing under the
   laws of the State of Ohio and has the requisite corporate power and authority
   to own its properties and to carry on the business in which it is now
   engaged. Security owns all of the capital stock of Security Bank free and
   clear of all liens and security interests.

2. All necessary corporate proceedings of Security have been duly taken to
   authorize the execution, delivery and performance of the Agreement by
   Security and the consummation of the transactions contemplated by the
   Agreement, subject in all events to any conditions stated in said Agreement.
   The Agreement constitutes the legal, valid and binding obligation of
   Security, enforceable in accordance with its terms, except:

   a. as such enforceability may be limited by bankruptcy, insolvency,
      reorganization, fraudulent conveyance or similar laws affecting creditors'
      rights; and

   b. that the remedy of specific performance and injunctive and other forms of
      equitable relief are subject to certain equitable defenses and to the
      discretion of the court before which any proceedings may be brought.

3. The execution, delivery and performance of the Agreement by Security will not
   violate or result in a breach of any term of Security's Articles of
   Incorporation or Code of Regulations, or violate, result in a breach of, or
   constitute a default under any term of any material agreement known to us to
   which Security is a party.



                                      B-2
<PAGE>   183
4. Security Bank is a national banking association validly existing under the
   laws of the United States of America and has the requisite corporate power
   and authority to own its properties and carry on the business in which it is
   now engaged.

5. The authorized capital stock of Security consists of 11,000,000, shares of
   common stock, par value $3.125 per share, 5,106,384 of which are outstanding
   To our knowledge, there are no outstanding options, warrants, or other rights
   to acquire, or securities convertible into any capital stock of Security. The
   outstanding shares of common stock of Security are, and the shares to be
   issued in accordance with the Agreement will be, validly authorized and
   issued, and non-assessable, and not, to the best of our knowledge, issued in
   violation of the pre-emptive rights of any person.

6. To our knowledge, except as disclosed herein, there is no litigation, action,
   suit, investigation or proceeding pending or, to the best of our knowledge
   after due inquiry of Security and its executive officers, overtly threatened
   against or affecting Security or involving any of its respective properties
   or assets, at law or in equity, before any federal, state, municipal, local
   or other governmental authority.

7. All consents or approvals of any regulatory authority having jurisdiction
   over Security or its subsidiaries that are required to be obtained in
   connection with the Merger and the transactions contemplated by the Agreement
   have been obtained.

8. The Registration Statement on Form S-4 filed by Security pursuant to the
   Agreement has become effective and no stop order revoking such effectiveness
   has been issued or has been threatened.

This opinion is solely for the benefit of the addressee hereof and may not be
relied upon by any other person or party or in any other context without our
prior written consent. This opinion is delivered as of the date hereof, and we
expressly disclaim any undertaking to update it.

Very truly yours,

                          Opinion of Financial Advisor









February 20, 1996




Board of Directors
CitNat Bancorp, Inc.
1 Monument Square
Urbana, OH  43078-2001

Dear Members of the Board:

You have requested our opinion as investment bankers as to the fairness, from a
financial perspective, to the common shareholders of CitNat Bancorp, Inc.,
Urbana, Ohio (the "Company") of the proposed merger of the Company with Security
Banc Corporation, Springfield, Ohio ("Security"). In the proposed merger,
Company shareholders will receive Security common shares equal to 2.1704 per
Company common share and Security common shares equal to 0.7791 per Company
option share for a total of 908,072 Security shares equal to an aggregate value
of $26,107,070.

Professional Bank Services, Inc. ("PBS") is a bank consulting firm and as part
of its investment banking business is continually engaged in reviewing the
fairness, from a financial perspective, of bank acquisition transactions and in
the valuation of banks and other businesses and their securities in connection
with mergers, acquisitions, estate settlements and other purposes. We are
independent with respect to the parties of the proposed transaction.

For purposes of this opinion, PBS reviewed and analyzed the historical
performance of the Company and its wholly owned subsidiary, The Citizens
National Bank of Urbana, Urbana, Ohio (the "Bank") contained in: (i) Audited
Financial Statements of the Company as of December 31, 1992, 1993, 1994 and
1995; (ii) December 31, 1995 Consolidated Reports of Condition and Income filed
with the Federal Deposit Insurance Corporation by the Bank; (iii) September 30,
1995 Uniform Bank Performance Report of the Bank; (iv) historical common stock
trading activity of the Company; and (v) the premises and other fixed assets. We
have reviewed and tabulated statistical data regarding the loan portfolio,
securities portfolio and other performance 



                                      B-4
<PAGE>   185
ratios and statistics. Financial projections were prepared and analyzed as well
as other financial studies, analyses and investigations as deemed relevant for
the purposes of this opinion. In review of the aforementioned information, we
have taken into account our assessment of general market and financial
conditions, our experience in other transactions, and our knowledge of the
banking industry generally.

In conjunction with our opinion, we have evaluated the historical performance
and current financial condition of Security contained in: (i) September 30, 1995
financial information; (ii) Annual Report to Shareholders for the years ending
December 31, 1994 and 1995; (iii) historical common stock trading and dividend
activity to date; and (iv) the financial terms of certain other comparable
transactions. We have prepared and analyzed the pro forma consolidated financial
condition of the Company and Security. We have reviewed and tabulated
consolidated statistical data regarding growth, growth prospects for service
markets, liquidity, asset composition and quality, profitability, leverage and
capital adequacy.

We have not compiled, reviewed or audited the financial statements of the
Company or Security, nor have we independently verified any of the information
reviewed; we have relied upon such information as being complete and accurate in
all material respects. We have not made independent evaluation of the assets of
the Company or Security.

Based on the foregoing and all other factors deemed relevant, it is our opinion
as investment bankers, that, as of the date hereof, the consideration proposed
to be received by the shareholders of the Company is fair and equitable from a
financial perspective.

                                          PROFESSIONAL BANK SERVICES, INC.

                                    EXHIBIT C

                        Ohio Revised Code Section 1701.85
          Qualifications of and Procedures for Dissenting Shareholders

                  Section 1701.85 - Qualifications of and Procedures for
Dissenting Shareholders.

(A)  (1)    A shareholder of a domestic corporation is entitled to relief as
            a dissenting shareholder in respect of the proposals 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 10 days after the date on which the
            vote on such proposal was taken at the meeting of the shareholders,
            the 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, stating 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 1701.801 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 20 days after he has been sent the notice
            provided in Section 1701.80 or 1701.801 of the Revised Code, the
            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 corporation, whether 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, he, within 15
            days from the date of the sending of such request, shall deliver to
            the corporation the certificates requested, in order 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 shareholder. Failure on the part of the shareholder to deliver
            such certificates terminates his rights as a dissenting shareholder,
            at the option of the corporation, exercised by written notice sent
            to him within 20 days after the lapse of the 15 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 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 certificate 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. Such request by the 




                                      C-1
<PAGE>   187
            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 shall have come to an
     agreement on the fair cash value per share of the shares as to which he
     seeks relief, the shareholder or the corporation, which in case of a merger
     or consolidation may be the surviving or the new corporation, within three
     months after the service of the demand by the shareholder, may file a
     complaint in the court of common pleas of the county in which the principal
     office of the corporation which issued such shares is located, or was
     located at the time 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 the period of three months, 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 complaint
     is required. Upon the filing of the 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 the 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 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 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 as agreed upon by the parties or as 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 such
     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 that 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, under no compulsion to
     sell, would be willing to accept, and that a willing buyer, under no
     compulsion to purchase, would be willing to pay, but in no event shall the
     fair cash value of it 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.



                                      C-2
<PAGE>   188
(D)  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:

     (1) Such shareholder has not complied with this section, unless the
         corporation by its directors waives such failure;

     (2) The corporation abandons, or is finally enjoined or prevented from
         carrying out, or the shareholders rescind their adoption, of the action
         involved;

     (3) The shareholder withdraws his demand, with the consent of the
         corporation by its directors;

     (4) The corporation and the dissenting shareholder shall not have come to
         an agreement as to the fair cash value per share, and neither the
         shareholder nor the corporation shall have filed or joined in a
         complaint under Division (B) of this section within the period
         provided.

(E)  From the time of giving 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 otherwise 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.

                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Ohio General Corporation Law ("OGCL") provides that Ohio corporations
may indemnify an individual made a party to any threatened, pending, or
completed action, suit or proceeding whether civil, criminal, administrative or
investigative, because the individual is or was a director, officer, employee or
agent of the corporation, against liability incurred in the proceeding if the
person: (i) acted in good faith and (ii) the individual believes his conduct was
in the corporation's best interest or was not opposed to the corporation's best
interest.

         The OGCL further provides that a corporation shall indemnify an
individual who was fully successful on the merits or otherwise in any proceeding
to which the director, officer, employee or agent was a party because the
individual was or is a director, officer, employee or agent of the corporation,
for reasonable expenses incurred by the director in connection with the
proceeding. The OGCL also provides that a corporation may purchase and maintain
insurance on behalf of the individual who is or was a director, officer,
employee or agent of the corporation or who, while a director, officer, employee
or agent of the corporation is or was serving at the request of the corporation
as a director, officer, partner, trustee, employer or agent of another foreign
or domestic corporation, partnership, joint venture, trust, employee benefit
plan or other enterprises, against liability asserted against or incurred by the
individual in that capacity or arising from the individual status as a director,
officer, employee, or agent.

         Registrant maintains a directors' and officers' liability insurance
policy, including bank reimbursement, for the purpose of providing
indemnification to its directors and officers in the event of such a threatened,
pending or completed action.

ITEM 22. UNDERTAKINGS.

A.       The undersigned Registrant hereby undertakes as follows:

         (a)      The undersigned Registrant hereby undertakes:

                  (1)      To file, during any period in which offers or sales
                           are being made, a post-effective amendment to this
                           Registration Statement:

                           (i)      To include any prospectus required by
                                    Section 10(a)(3) of the Securities Act of
                                    1933;

                           (ii)     To reflect in the Prospectus any facts or
                                    events arising after the Effective Date of
                                    the Registration Statement (or the most
                                    recent post-effective amendment thereof)
                                    which, individually or in the aggregate,
                                    represent a fundamental change in the
                                    information set forth in the Registration
                                    Statement;

                           (iii)    To include any material information with
                                    respect to the plan of distribution not
                                    previously disclosed in the Registration
                                    Statement or any material change to the
                                    information set forth in the Registration
                                    Statement;

                  (2)      That, for the purpose 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.

                  (3)      To remove from registration by means of a
                           post-effective amendment any of the securities being
                           registered which remain unsold at the termination of
                           the offering.

         (b)      The undersigned Registrant hereby undertakes that, for
                  purposes of determining any liability under the Securities Act
                  of 1933, each filing of the Registrant's annual report
                  pursuant to Section 13(a) or Section 15(d) of the Securities
                  Exchange Act of 1934 that is incorporated by reference in this
                  Registration Statement shall be deemed to be a new
                  Registration Statement relating to the securities offered
                  therein, and the offering of such securities at that time
                  shall be deemed to be the initial bona fide offering thereof.

         (c)      Insofar as indemnification for liabilities arising under the
                  Securities Act of 1933 may be permitted to officers,
                  directors, 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 

                                                                  Part II page 4
<PAGE>   193
                  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 that matter has been settled by
                  controlling precedent, submit to a court of appropriate
                  jurisdiction the question of 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.

B.       The undersigned Registrant hereby undertakes to respond to requests for
         information that are incorporated by reference into the
         Prospectus/Proxy Statement 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 the documents
         filed subsequent to the Effective Date of this Registration Statement
         through the date of responding to the request.

C.       The undersigned Registrant hereby undertakes to supply by means of a
         post-effective amendment all information concerning a transaction, and
         the company being acquired involved therein, that was not the subject
         of and included in this Registration Statement when it became
         effective.

                                                                  Part II page 5

entered upon the books of the Corporation as the registered holder of such
share, shall have been given to the person in whose name such share appeared of
record.

         Section 5. Waiver of Notice. Any shareholder, either before or after
any meeting, may waive any notice required to be given by law or under these
Regulations and whenever all of the shareholders entitled to vote shall meet in
person or by proxy and consent to holding a meeting, it shall be valid for all
purposes without call or notice, and at such meeting any action may be taken.

         Section 6. Quorum. A majority of the outstanding capital stock,
represented in person or by proxy, shall constitute a quorum at any meeting of
the shareholders, unless otherwise provided by law; but less than a quorum may
adjourn any meeting, from time to time, and a meeting may be held, as adjourned,
without further notice. A majority of the votes cast shall decide every question
or matter submitted to the shareholders at any meeting, unless otherwise
provided by law or by the Articles of Incorporation.

         Section 7. Proxies. Any shareholder of record who is entitled to attend
a shareholders' meeting, or to vote thereat or to assent or give consents in

<PAGE>   3
represented at such meetings or to vote thereat or to assent or give consent in
writing, as the case may be, or to exercise any other of his rights, by proxy
or proxies appointed by a writing signed by such shareholder, which need not be
sealed, witnessed or acknowledged.

        A telegram, cablegram, wireless message or photogram appearing to have
been transmitted by a shareholder, or a photograph, photostatic or equivalent
reproduction of a writing appointing a proxy or proxies shall be a sufficient
writing.

        Unless the writing appointing a proxy or proxies otherwise provides:

        No appointment of a proxy shall be valid after the expiration eleven
(11) months after it is made, unless the writing specifies the date on which it
is to expire or the length of time it is to continue in force.

        (1) Each and every proxy shall have the power of substitution, and when
three (3) or more persons are appointed, a majority of them or their respective
substitutes may appoint a substitute or substitutes to act for all;

        (2) If more than one proxy is appointed, then (a) with respect to
voting or giving consents at a shareholders' meeting, a majority of such
proxies as attend the meeting, or if only one attends then that one may
exercise all the voting and consenting authority thereat; and if an even
number attend and a majority do not agree on any particular issue, each proxy
so attending shall be entitled to exercise such authority with respect to an
equal number of shares; (b) with respect to exercising any other authority, a
majority may act for all;

        (3) A writing appointing a proxy shall not be revoked by the death or
incapacity of the maker unless before the vote is taken or the authority
granted is otherwise exercised, written notice of such death or incapacity is
given to the Corporation by the executor or the administrator of the estate of
such maker or by the fiduciary having control of the shares in respect of which
the proxy was appointed;

        (4) The presence of a shareholder at a meeting shall not operate to
revoke a writing appointing a proxy. A shareholder, without affecting any vote
previously taken, may revoke such writing not otherwise revoked by giving
notice to the Corporation in writing or in open meeting.

<PAGE>   4
         Section 8. Voting. At any meeting of the shareholders, each shareholder

books of the Corporation: (1) on the record date for the determination of
shareholders entitled to vote at such meeting, notwithstanding the prior or
subsequent sale, or other disposal of such share or shares or transfer of the
same on the books of the Corporation on or after the record date; or (2) if no
such record date shall have been fixed, then at the time of such meeting.

         Section 9. Financial Reports. At the annual meeting of shareholders, or
the meeting held in lieu thereof, there shall be laid before the shareholders a

the assets, liabilities, stated capital, and surplus (showing separately any
capital surplus arising from unrealized appreciation of assets, other capital
surplus, and earned surplus) of the Corporation as of a date not more than four
(4) months before such meeting; if such meeting is an adjourned meeting, said

of the meeting as originally convened; and (2) a statement of profit and loss
and surplus, including a summary of profits, dividends paid, and other changes
in the surplus accounts of the Corporation for the period commencing with the
date marking the end of the period for which the last preceding statement of

balance sheet.

         An opinion signed by the President or a Vice President or the Treasurer
or an Assistant Treasurer, or by a public accountant or firm of public
accountants, shall be appended to such financial statement, stating that the
financial statement presents fairly the Corporation's financial position and the
results of its operations in conformity with generally accepted accounting
principles applied on a basis consistent with that of the preceding period, or
such other opinion as is in accordance with sound accounting practice.

Gentlemen:

We have acted as counsel to Security Banc Corporation (the "Company") in

purpose of registering shares of the Company to be issued to shareholders of
CitNat Bancorp, Inc., pursuant to the terms and conditions of an Merger
Agreement dated March 14, 1996 (the "Agreement"). In connection with the filing
of the Registration Statement, we are providing this opinion as to the shares to
be registered under the Securities Act of 1933 and issued in connection with the
Agreement.

We are of the opinion that the shares of common stock of the Company are duly

be validly issued, fully paid and nonassessable.

This opinion is intended solely for your use and other than its inclusion in the
Registration Statement of the Company and referenced to it in the Prospectus
issued in connection therewith, may not be quoted, circulated or copied without
our express prior written consent.

Very truly yours,

EXHIBIT 8 - TAX OPINION

June 19, 1996

Board of Directors
Security Banc Corporation
40 S. Limestone Street
Springfield, OH  35502-1222

and

Board of Directors
CitNat Bancorp, Inc.
1 Monument Square
Urbana, OH  32078-2001

Gentlemen:

You have requested our opinion as to the federal income tax consequences of the
transactions contemplated by a certain Merger Agreement dated March 14, 1996 by
and between Security Banc Corporation ("Security") and CitNat Bancorp, Inc.
("CitNat"), hereinafter referred to as the "Agreement." Our opinion is made in
reliance upon and is limited to the following facts and circumstances:

FACTS

CitNat is an Ohio corporation, is a registered bank holding company and is
located in Urbana, Ohio. Security is an Ohio corporation, is a registered bank
holding company and is located in Springfield, Ohio.

Security and CitNat have only common shares outstanding. CitNat is to be merged
into Security, under the Articles of Incorporation of Security and in compliance
with applicable Ohio law.

Each share of CitNat outstanding on the effective date of the transaction will
be converted into shares of common stock of Security as provided by the
Agreement. The effect of the consummation of the transaction and the exchange of
shares will be that shareholders of CitNat will become shareholders of Security,
and Security will own all of the outstanding common stock of The Citizens
National Bank of Urbana, Ohio, a wholly owned subsidiary of CitNat.

The business of CitNat and Security (and affiliates) will continue substantially
unchanged after the effective date of the transaction.

No fractional shares will be issued in the transaction. In lieu thereof, holders
otherwise entitled to receive such fractional shares will be issued cash.
<PAGE>   2
We are not aware and have been advised by the management of CitNat that they
have no knowledge of any plan or intention on the part of shareholders of CitNat
to sell or otherwise dispose of an amount of the Security shares to be received
in the transaction, which could reduce CitNat's shareholders ownership of
Security shares after the merger of CitNat and Security to shares having an
aggregate value as of the date of the transaction, of less than fifty percent
(50%) of the value of all the formerly outstanding shares of CitNat as of the
same date.

The transaction will be carried out pursuant to and in accordance with all
applicable corporate and banking laws relating to the transaction. On the
effective date, Security will succeed to all assets of CitNat and will be liable
for the liabilities of CitNat then existing or arising as a result of the
transactions.

Following the consummation of the transaction resulting in the merger of CitNat
with and into Security, Security will continue to operate the business of CitNat
and its existing affiliates in substantially the same manner.

Arms-length negotiations were carried on between the management of Security and
management of CitNat 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 Security and CitNat, its 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 CitNat with and into Security will constitute a "Statutory
     Merger" within the meaning of Section 368(a)(1)(A) of the Internal Revenue
     Code of 1986, as amended, and CitNat and Security will each be a "party to
     a reorganization" within the meaning of Section 368(b).

2.   No gain or loss will be recognized by CitNat as a result of the transfer of
     its assets to and the assumption of its liabilities by Security. Section
     361(a) and 357(a).

3.   No gain or loss will be recognized by CitNat's shareholders who exchanged
     their respective shares solely for Security shares. Section 354(a).

4.   The basis of the Security shares received by CitNat's shareholders in
     exchange for their shares will be the same as the basis in the shares
     exchanged therefor, respectively. Section 358(a).

5.   The holding period of the Security shares received by CitNat's shareholders
     will include the period during which shares exchanged therefor were held,
     provided such shares were held as a capital asset. Section 1223(1).
<PAGE>   3
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 Internal Revenue
     Code of 1986, as amended. 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.

7.   Gain or loss will be recognized by each CitNat's shareholder who dissents
     and receives only cash in exchange for all of the shares owned by them.

This letter is solely for your information and use, and except: (i) for its
reliance upon by Security, CitNat and their respective 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,

are herein referred to as "Eligible Employees." Those directors who are not
regular employees of the Corporation or its Subsidiaries are not eligible to
participate in the Plan.

         4.  Shares Subject to Option.

         (a) The shares to be issued and delivered by the Corporation upon
exercise of options granted under the Plan are the Corporation's common shares,
6.25 par value, which may be either authorized but unissued shares or treasury
shares.

         (b) The aggregate number of common shares of the Corporation which may
be issued under the Plan shall not exceed twenty-five thousand (25,000) shares;
subject, however, to the adjustment provided in Paragraph 8 in the event of
stock splits, stock dividends, exchange of
<PAGE>   2
shares or the like occurring after the effective date of this Plan. No option
may be granted under this Plan which could cause such maximum limit to be
exceeded.

         (c) Common shares covered by an option which is no longer exercisable
with respect to such shares shall again be available for issuance in connection
with other options granted under this Plan.

         5. Grant of Options. The Board may from time to time, in its discretion
and subject to the provisions of the Plan, grant options to any or all Eligible
Employees. Employees to whom options have been granted are herein referred to as
"Optionees." Each option shall be embodied in an "Option Agreement" signed by
the Optionee and the Corporation providing that the option shall be subject to
the provisions of this Plan and containing such other provisions as the Board
may prescribe not inconsistent with the Plan.

         6. Terms and Conditions of Option. All options granted under the Plan
shall contain such terms and conditions as the Board from time to time
determines, subject to the foregoing and following limitations and requirements.

         (a) Form of Option: Incentive Options and Nonqualified Options may be
granted under this Plan. An "Incentive Option" shall mean an option granted
under this Plan which is designated to be an incentive stock option under the
provisions of Code Section 422A; and any provisions elsewhere in this Plan or in
any such Incentive Option which would prevent such option from being an
incentive stock option may be deleted and/or voided retroactively to the date of
the granting of such option by action of the Board. A "Nonqualified Option"
shall mean an option granted under this Plan which is not an incentive stock
option under the provisions of Code Section 422A. Such Nonqualified Option shall
not be affected by any actions taken retroactively as provided above with
respect to Incentive Options.

         (b) Option Price: The option price per share shall not be less than
100% of the fair market value of the Corporation's common shares on the date the
option is granted, as determined by the Board in a manner consistent with the
requirements of the Code for incentive stock options.
<PAGE>   3
         (c) 10% Shareholder: Notwithstanding any other provision of this Plan,
with respect to an Incentive Option granted to an Optionee who at the time such
option is granted owns stock processing more than 10 percent of the total
combined voting power of all classes of stock of the Corporation or its
Subsidiaries, the option price per share shall be at least 110% of the fair
market value of the common shares subject to the option and such option may not
be exercised after the expiration of five years from the date the option is
granted.

         (d) Period within which option may be exercised: Except as provided in
Paragraph 9 below, not more than the following percentages of each option
granted under this Plan may be exercised prior to the expiration of the
following number of years after the effective date of the grant of such option:

<TABLE>

              Less than 1                                        0%
              At least 1 but less than 2                        20%
              At least 2 but less than 3                        40%
              At least 3 but less than 4                        60%
              At least 4 but less than 5                        80%
              At least 5                                       100%
</TABLE>

No option may be exercised after the expiration of ten years from the date the
option is granted.

         (e) Termination of option by reason of termination of employment: If an
Optionee's employment with the Corporation and its Subsidiaries terminates, all
options granted under this Plan to such Optionee which are not exercisable on
the date of such termination of employment shall immediately terminate. Any
remaining options shall terminate if not exercised before the expiration of the
following periods, or at such earlier time as may be applicable under paragraph
6(d) above:

              (i) seven (7) days following such termination of employment, if
such termination was not as a result of death, disability (disability within the
meaning of Code Section 105(d)(4)), or retirement of the Optionee;
<PAGE>   4
              (ii) thirty (30) days following such termination of employment, if
such termination of employment was because of retirement under the provisions of
any retirement plan of the Corporation and/or any Subsidiary; or

              (iii) one (1) year following the date of death or commencement of
disability, if the Optionee was an employee of the Corporation and/or any
Subsidiary at the time of his death or the commencement of disability.

         (f) Nontransferability; Exception: Each option and all rights
thereunder shall be exercisable during the Optionee's lifetime only by him and
shall be nonassignable and nontransferable by the Optionee. In the event of the
Optionee's death, such options and rights thereunder are transferable by his
will or by the laws of descent and distribution. In the event the death of an
Optionee occurs, the representative or representatives of his estate, or the
person or persons who acquired (by bequest or inheritance) the rights to
exercise his stock options granted under this Plan may exercise any of the
unexercised options in whole or in part prior to the expiration of the
applicable exercise period as specified in Paragraph 6(e) above.

         (g) More than one option granted to an Optionee: More than one option
and more than one form of option may be granted to an Optionee under this Plan;
provided, however, that the aggregate fair market value (determined as of the
time the Option is granted) of the shares with respect to which incentive stock
options are exercisable for the first time by any Optionee during any calendar
year (under this Plan and all such plans of the Corporation and any parent or
subsidiary corporation) shall not exceed $100,000. A single option grant may
include both an Incentive Option and a Nonqualified Option.

         (h) Compliance with securities laws: Options granted and shares issued
by the Corporation upon exercise of options shall be granted and issued only in
full compliance with all applicable securities laws, including laws, rules and
regulations of the Securities and Exchange Commission and applicable state Blue
Sky laws. With respect thereto, the Board may impose such conditions on
transfer, restrictions and limitations as it may deem necessary and appropriate
to assure compliance with such applicable securities laws.
<PAGE>   5
         7. Method of Exercise. An option granted under this Plan that is
eligible to be exercised may be exercised by written notice to the Board, signed
by the Optionee, or by such other person as is entitled to exercise such option.
The notice of exercise shall state the number of shares in respect of which the
option is being exercised and shall either be accompanied by the payment of the
full option price for such shares or shall fix a date (not more than ten
business days from the date of such notice) for the payment of the full purchase
price of the shares being purchased. All or any portion of the payment may be
made by the transfer of common shares of the Corporation from the Optionee to
the Corporation to the extent permitted by law. Such shares shall be valued for
this purpose at their fair market value on the date they are transferred to the
Corporation as payment determined in the same manner as is provided in Paragraph
6(b) hereof. A certificate or certificates for the common shares of the
Corporation purchased through the exercise of an option shall be issued in
regular course after the exercise of the option and payment therefor. During the
option period no person entitled to exercise any option granted under this Plan
shall have any of the rights or privileges of a shareholder with respect to any
shares issuable upon exercise of such option until certificates representing
such shares shall have been issued and delivered.

         8. Shares Adjustments. In the event there is any change in the
Corporation's common shares resulting from stock splits, stock dividends,
combinations or exchange of shares, or other similar capital adjustments,
equitable proportionate adjustments shall be made by the Board in (a) the number
of shares available for options under this Plan, (b) the number of shares
subject to options granted under this Plan, and (c) the option price of optioned
shares.

         9. Merger, Consolidation or Sale of Assets. In the event any person, by
any means of purchase or acquisition, becomes the "beneficial owner" (as defined
in Rule 13d-3 promulgated by the Securities and Exchange Commission under the
Securities Exchange Act of 1934 as in effect on December 15, 1987, or any
successor provision thereto) of more than 50% of the outstanding shares of the
Corporation's common stock, then with respect to each Optionee all Incentive
Options and Nonqualified Options which were outstanding at the time of such
event shall immediately become exercisable in full.
<PAGE>   6
         In the event of the execution of an agreement of reorganization, merger
or consolidation of the Corporation with one or more corporations as a result of
which the Corporation is not to be the surviving corporation (whether or not the
Corporation shall be dissolved or liquidated) or the execution of an agreement
of sale or transfer of all or substantially all of the assets of the
Corporation, then with respect to each Optionee all Incentive Options and
Nonqualified Options which were outstanding at the time of such event shall
immediately become exercisable in full, unless such agreement provides that the
successor or transferee corporation shall continue this Plan and assume all
obligations under this Plan in a manner consistent with Code Section 425(a) as
amended or any successor section thereto. If the successor or transferee
corporation does not obligate itself to continue this Plan as provided above,
this Plan and the unexercised portions of all stock options granted pursuant to
this Plan shall terminate as of the effective date of any such transaction. If
practical, the Corporation shall give each Optionee notice of the execution of
the agreement which has caused options to become immediately exercisable and
twenty (20) days prior notice of the effective date of any possible transaction
which would cause the options to terminate.

         10. Amendment or Termination. The Board may terminate this Plan at any
time and may amend the Plan at any time without obtaining any approval of the
Corporation's shareholders; except that the Plan may not be amended (a) to
increase the aggregate number of shares issuable under the Plan (excepting
proportionate adjustments made under Paragraph 8 to give effect to stock splits,
etc.); (b) to change the option price of optioned stock (excepting proportionate
adjustments made under Paragraph 8); (c) to change the requirement that the
option price per share of common stock covered by an option granted under this
plan not be less than 100% of the fair market value of the Corporation's common
stock on the date such option is granted; (d) to extend the time within which
options may be granted or the time within which a granted option may b
exercised; or (e) to change without the consent of the Optionee (or his, or his
estate's legal representative), any option previously granted to him under the
plan. If the Plan is terminated, any unexercised option shall continue to be
exercisable in accordance with its terms and the terms of this Plan, except as
provided in Paragraph 9 above.
<PAGE>   7
         11. Corporation Responsibility. All expenses of this Plan, including
the cost of maintaining records, shall be borne by the Corporation. The
Corporation shall have no responsibility or liability (other than under
applicable Securities Acts) for any act or thing done or left undone with
respect to the price, time, quantity or other conditions and circumstances of
the purchase of shares under the terms of the Plan, so long as the Corporation
acts in good faith.

         12. Implied Consent of Optionees. Every Optionee, by his acceptance of
an option under this Plan, shall be deemed to have consented to be bound on his
own behalf and on behalf of his heirs, assigns, and legal representatives, by
all of the terms and conditions of this Plan.

         13. No Effect on Employment Status. The fact that an employee has been
granted an option under this Plan shall not limit or otherwise qualify the right
of his employer to terminate his employment at any time.

         14. Duration and Termination of the Plan. The Plan shall become
effective on December 15, 1987, if approved and adopted by majority vote of the
shareholders of the Corporation within twelve months after such date; and if not
so approved and adopted, shall be of no force and effect. No option shall be
granted under the Plan subsequent to December 14, 1997.

Letter to the Shareholders



                             [Photo]


      Once again, we are pleased to present an annual report to shareholders
which reflects the continuing growth, strength and stability of Security Banc
Corporation. The following pages of facts and figures for 1995 represent
another prosperous year and reflect the economic makeup of our communties. This
year's annual report is dedicated to our Board of Directors. Our goal is for
the composition of our Board of Directors to mirror the diverse interest and
opinions of our shareholders. By achieving this, we live up to our hometown
philosophy. A philosophy which provides our shareholders and our customers with
the advantages and responsiveness of local ownership and local leadership. It
is this mind set which creates a neighborhood atmosphere in every one of our
markets. As we continue on our path of growth--from steps such as opening a new
service or office, to entering new opportunities--we will remain committed to
local community leadership.
<PAGE>   5


      As partners, presidents or owners of local business ventures, our Board
of Directors bring with them a diversity of information and experience as well
as knowledge of the commitment to the communities and people we serve. This
combined pool of wisdom benefits the Corporation by expanding the base of
information considered during the decision making process. Board members,
active in the business community, are able to create policies which respond to
community needs and benefit shareholders. By establishing effective corporate
policies, the Board empowers the senior management staff of Security Banc
Corporation to function to their highest potential. It is this type of
leadership which creates a thriving work environment and a thriving
institution.
      Security Banc Corporation's net income for the year 1995 was $11,082,000,
an increase of 8% over the $10,304,000 for the previous year. This year's
earnings per share increased 7%, from $2.03 to $2.17. Shareholders' equity is
well in excess of regulatory requirements. The national average return on
assets and equity for banks under one billion in assets is 1.26% and 13.64%,
respectively. Security Banc continues to exceed these with a return on assets
of 2.13% and a return on equity of 16.13%.
      The cash dividends of $0.73 per share is an increase of 11% over 1994.
Total assets extended to $535,975,000 at December 31, 1995. Deposits increased
$9,489,000 to $436,256,000, while total loans increased $524,000 to
$314,575,000. The stock market value is $28.50, adjusted to reflect the 2 for 1
stock split during the second quarter. Our financial stability continues to
reflect a history of high quality assets and net loan losses of 0.19% of
average loans.
      The high performance of Security Banc Corporation continues to receive
industry recognition from Bauer Financial Reports, Inc., Sheshunoff and
VERIBANC, Inc. These recognitions are based on key indicators including market
share, profitability and return to shareholders. This excellent ranking among
our peers points to the leadership provided by our Board of Directors and
management ability of our staff.
      In an era of bank mergers and multi-state financial institutions,
Security Banc Corporation continues to shine as a hometown institution. Our
local ownership and emphasis on personal service, positions us ahead of the
competition when it comes to neighbor-to-neighbor service. We created the
"hometown touch," and we continue to provide the real thing.
      Last year we reported to you that we had initiated a strategic planning
process in 1994, a process which we said would be ongoing. During 1995 we
reaped many benefits from these efforts. We held our first Annual Employee
Meeting and drafted a new Vision Statement which will keep us focused on
sustained growth, both financially and as an institution which fosters employee
development. We are committed to having an organizational structure which
encourages a free flow of ideas from all levels of staff and management. Just
as we realize the benefits of diversity on our Board, we acknowledge the
benefits of diverse thought among our staff. Security staff will be trained and
empowered to make decisions which will provide the highest quality of customer
service, and the bank's products and delivery system will be continually
evaluated for suitability, location and profitability. We will use
state-of-the-art management information systems to analyze and prioritize our
product and service needs. A major step toward this goal was accomplished this
past year by installing a new data processing system. As we continue to
integrate our strategic plan, we will incorporate our Core Values of integrity,
fairness, social responsibility and fun.
      A new director, Larry E. Kaffenbarger, was appointed to the Board last
year. His contributions have added a new dimension to our Board. We are
confident that with the support of our shareholders, the leadership of our
Board and the dedication of our management staff and employees, we will
continue to assess and adjust our operations to meet the needs of our community
and our customers.
      We thank our directors and our employees for their contribution in 1995
and look forward to 1996 with the knowledge that your hometown bank, led by
hometown people, will continue to provide returns on shareholder investments
and maintain our legacy of personal service to customers.


                                                /s/ Harry Egger

of Financial Condition and Results of Operations

     In the following pages, the analysis of the financial condition and

NET INTEREST INCOME

    A major share of the Corporation's income results from the spread between
income on interest earning assets, such as loans and securities, and the
interest expense on liabilities used to fund those assets. The difference
between interest earned and interest expensed is referred to as net interest
income in the Consolidated Statement of Income. Net interest income is affected
by changes in both interest rates and the amount of interest earning assets and
interest bearing liabilities outstanding. Net interest margin on interest
earning assets is the amount earned on assets, on a taxable equivalent basis,
divided by the average earning assets outstanding.

    Table II, entitled Average Balance Sheets and Analysis of Net Interest
Income, compares the changes in revenue and interest earning assets
outstanding, and interest cost and liabilities outstanding for the years ended
December 31, 1995, 1994, and 1993.

    The Corporation's net interest income on a taxable equivalent basis was
$26,930,000, $25,536,000 and $24,017,000 in 1995, 1994 and 1993, respectively.
Total average earning assets increased to $488,128,000 in 1995, compared to
$480,505,000 in 1994 and $464,153,000 in 1993. Earning assets are total loans,
total securities, interest bearing deposits with other banks and federal funds
sold. Average total loans increased $14,979,000 to $314,497,000. Average
securities, interest bearing deposits with other banks, and federal funds sold
decreased a combined total of $7,356,000.

    Total average interest bearing liabilities increased $83,000 to
$372,088,000 in 1995. Average time deposits attributed to the increase
representing $26,783,000. Average purchased funds increased $1,811,000. Average
NOW, Money Fund and savings decreased $5,762,000, $4,859,000 and $17,890,000,
respectively.

    Average earning assets of $488,128,000 in 1995 contributed a tax equivalent
interest income of $41,124,000 with a yield of eight point forty-two percent
(8.42%).

    Average interest bearing liabilities of $372,088,000 in 1995 contributed
interest expense of $14,194,000.

    Table III, entitled Analysis of Net Interest Income Changes, translates the
dollar changes in taxable equivalent net interest margin into (1) changes due
to volume or (2) changes due to average yields on interest earning assets and
average rates for sources of funds on which interest expense is incurred.

OTHER OPERATING INCOME

    Other operating income is comprised of trust income, service charges on
deposit accounts, security gains, and other items of income not directly
resulting from interest earning assets. These items comprise safe deposit box
fees, exchange and collection fees, investor service fees, gain (loss) on the
sale of loans and miscellaneous other income.

$147,647,000 in 1995 yielding an average rate of nine point twenty-two percent
(9.22%). Average real estate loans decreased point one percent (0.1%) to
$83,820,000, yielding an average rate of eight point forty-one percent (8.41%).
Average consumer loans, which include home equity loans, increased twelve point
forty-five percent (12.45%) to $83,030,000, yielding an average rate of ten
point twenty-three percent (10.23%).

    Under-performing assets consist of (1) non-accrual loans on which the
ultimate collectibility of the full amount of interest is uncertain but the
principal is currently considered fully collectible, (2) loans past due

ninety (90) days or more as to principal or interest and (3) other real estate
owned. Under-performing assets as of December 31, 1995 were $4,150,000.
    The Corporation provides, as expense, an amount which reflects expected
loan losses. This provision is based on the growth of the loan portfolio, local
economic conditions, and on recent loan loss experience and is called the
provision for loan losses in the Consolidated Statement of Income. Actual
losses on loans are charged against the reserve built up on the Consolidated
Statement of Condition through the allowance for loan losses. The amount of
loans actually removed as assets from the Consolidated Statement of Condition
is referred to as charge-offs. Netting out recoveries on previously charged-off
assets with current year charge-offs provides net charge-offs.
    Net charge-offs in 1995 increased to $605,000 from $416,000 in 1994. The
provision for loan losses was $800,000 in 1995 and 1994.  The allowance for
loan losses at December 31, 1995 was equivalent to one point nineteen percent
(1.19%) of loans outstanding.
    The following table presents loan loss data for the most recent five (5)
year period.

LIQUIDITY AND INTEREST RATE SENSITIVITY

    The Corporation's Asset/Liability Management Committee is charged with the
responsibility of maintaining an adequate level of liquidity and of managing
the risks associated with interest rate changes while sustaining a stable
growth in net interest income. The maintenance of an adequate level of
liquidity is necessary to ensure that sufficient funds are available to meet
customer loan demand and deposit withdrawals. The asset liquidity sources
consist of short term marketable securities, federal funds sold, maturing loans
and certificates of deposit. Interest rate management seeks to maintain a
balance between steady net interest growth and the risks associated with
interest rate fluctuations.The strategy is to minimize interest rate risk
through the matching of the repricing period of interest earning assets and
interest bearing liabilities.

    The Corporation has a net asset position of $77,122,000 at the one (1) year
interval or a sensitivity ratio of one point forty-two (1.42). This ratio
indicates that, in a declining interest rate environment, those assets that are
due to reprice would be replaced at a decreased interest yield at a faster pace
than maturing liabilities, having a negative impact on the net interest margin.
In an increasing rate environment, those assets that are due to reprice would
be replaced at a higher interest yield, improving the net interest margin.

CAPITAL RESOURCES

    Federal Reserve Board standards require banks and bank holding companies to
maintain capital based on "risk-adjusted" assets so that categories of assets
with potentially higher credit risk will require more capital backing than
assets with lower risk. In addition, banks and bank holding companies are
required to maintain capital to support on a risk-adjusted basis, certain
off-balance-sheet activities such as loan commitments.

   The Federal Reserve Board standards classify capital into tiers.  All banks
are required to meet a minimum ratio of eight point zero percent (8.0%) of
qualifying total capital to risk-adjusted total assets.

   Security Banc Corporation maintains a high level of capital as a margin of
safety for its stockholders and depositors. Applying the new risk-based capital
guidelines; total capital to total risk-weighted assets was twenty-one point
ninty-nine percent (21.99%) in 1995 and twenty point seventy-seven percent
(20.77%) in 1994, well above the minimum established guidelines.

Report of Independent Auditors

Board of Directors

Security Banc Corporation

We have audited the accompanying consolidated statement of condition of
Security Banc Corporation and subsidiaries as of December 31, 1995 and 1994,
and the related consolidated statements of income, shareholders' equity, and
cash flows for each of the three years in the period ended December 31, 1995.
These financial statements are the responsibility of the Corporation's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Security Banc
Corporation and subsidiaries at December 31, 1995 and 1994, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1995 in conformity with generally
accepted accounting principles.

Notes to Consolidated Financial Statements

    December 31, 1995

1. ORGANIZATION

    The Corporation is a bank holding company headquartered in Springfield,
Ohio. The bank, Security National Bank is engaged in the general commercial
banking and trust business, primarily in Central Ohio.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the consolidated financial
statements and accompanying notes. Actual results could differ from those
estimates.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The accounting and reporting policies of Security Banc Corporation are
based on generally accepted accounting principles and conform to general
practices within the banking industry. The following is a description of the
significant accounting policies followed by Security Banc Corporation.

CONSOLIDATION

    The consolidated financial statements include the accounts of Security Banc
Corporation and its wholly owned subsidiaries, Security National Bank and Trust
Co., and Security Community Urban Redevelopment Corporation. All significant
intercompany accounts and transactions have been eliminated in consolidation.

CORE DEPOSIT INTANGIBLE ASSET

    The acquired core deposit intangible asset is amortized on an accelerated
basis over ten (10) years.

INVESTMENT SECURITIES

    Securities held-to-maturity and available-for-sale: Management determines
the appropriate classification of debt securities at the time of purchase and
reevaluates such designation as of each balance sheet date. Debt securities are
classified as held-to-maturity when Security Banc Corporation has the positive
intent and ability to hold the securities to maturity. Held-to-maturity
securities are stated at amortized cost.

    Debt securities not classified as held-to-maturity or trading and
marketable equity securities not classified as trading are classified as
available-for-sale. Available-for-sale securities are stated at fair value,
with the unrealized gains and losses, net of tax, reported in a separate
component of shareholders' equity.

    The amortized cost of debt securities classified as held-to-maturity or
available-for-sale is adjusted for amortization of premiums and accretion of
discounts to maturity, or in the case of mortgage-backed securities, over the
estimated life of the security. Such amortization is included in interest
income from investments. Interest and dividends are included in interest income
from investments. Realized gains and losses, and declines in value judged to be
other-than-temporary are included in net securities gains (losses). The cost of
securities sold is based on the specific identification method.

LOANS

    Loans are stated at the principal amount outstanding, net of unearned
income. Interest income on other loans is primarily accrued using the simple
interest method based on the principal amounts outstanding. Loan fees received
in excess of direct costs involved in origination of a loan are amortized over
the estimated loan term. Accrual of interest is discontinued when circumstances
indicate that collection of loan principal is questionable.

    The company has adopted Financial Accounting Standards Board Statement No.
114, "Accounting by Creditors for Impairment of a Loan," effective January 1,
1995. As a result of applying the new rules, certain impaired loans are
reported at the present value of expected future cash flows using the loan's
effective interest rate, or as a practical expedient, at the loan's observable
market price or the fair value of the collateral if the loan is collateral
dependent.  The adoption of this statement did not have a material impact on
Security Banc Corporation's financial statements.

ALLOWANCE FOR POSSIBLE LOAN LOSSES

    The allowance for possible loan losses is available for loan charge-offs.
The adequacy of the allowance is based on Management's continuous evaluation of
key factors in the loan portfolio with consideration given to current economic
conditions and past charge-off experience.

PREMISES AND EQUIPMENT

    Premises and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation of premises and equipment is determined using the
straight-line method over the estimated lives of the respective assets.
Maintenance and repairs are charged to expense as incurred, while renewals and
betterments are capitalized.

INCOME TAXES

    Certain income and expense items are accounted for in different time
periods for financial reporting purposes than for income tax purposes.
Appropriate provisions are made in the financial statements for deferred taxes
in recognition of these temporary differences.

NET INCOME PER SHARE

    Income per share is computed on the basis of weighted average shares
outstanding.

CASH FLOWS

    For purposes of reporting cash flows, cash and cash requirements include
cash on hand, amounts due from banks and federal funds sold. Federal funds are
purchased for one-day periods.

    Interest paid by Security Banc Corporation in 1995, 1994 and 1993 was
$14,867,000, $10,468,000, and $12,161,000, respectively.

FAIR VALUES OF FINANCIAL INSTRUMENTS

    The following methods and assumptions were used by the bank in estimating
its fair value disclosures for financial instruments.

     Cash and cash equivalent and interest-bearing deposits with other banks:
The carrying amounts reported in the balance sheet for cash and short-term
instruments approximate those assets' fair values.

    Investment Securities: Fair values for investment securities are based on
quoted market prices, where available. If quoted market prices are not
available, fair values are based on quoted market prices of comparable
instruments.

    Loans receivable: For variable-rate loans that reprice frequently and with
no significant change in credit risk, fair values are based on carrying values.
The fair values for mortgage loans are based on quoted market prices of similar
loans sold in conjunction with securitization transactions, adjusted for
differences in loan characteristics. The fair values for other loans (i.e.,
commercial, agricultural and consumer) are estimated using

                "The true strength of success is the ability to withstand
                extremes.  Security Banc Corporation has remained stable and
                experienced continued growth through all economic conditions."

discounted cash flow analyses, using interest rates currently being offered for
loans with similar terms to borrowers of similar credit quality. The carrying
amount of accrued interest approximates its fair value.

    Off-balance-sheet instruments: The carrying amounts reported for Security
Banc Corporation's off-balance-sheet instruments (letters of credit and lending
commitments) approximate those assets' fair value.

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

    Short-term borrowings: The carrying amounts of federal funds purchased and
securities sold under agreement to repurchase approximate their fair values.

RECLASSIFICATIONS

    Certain 1994 amounts have been reclassified to conform with the current
year presentation.


2.  ACCOUNTING CHANGES

    The Financial Accounting Standards Board's Statement of Financial
Accounting Standards No. 121 "Accounting for the Impairment of Long-Lived
Assets and For Long-Lived Assets to be Disposed Of" requires that long-lived
assets and certain identifiable intangibles be reviewed for impairments. The
Statement prescribes when assets should be reviewed, how to determine
impairment , and what financial disclosures are necessary.

    Additionally, Statement of Financial Accounting Standards No. 122
"Accounting for Mortgage Servicing Rights" requires the recognition of rights
to service loans for others as separate assets, however those servicing rights
are acquired.

    Both of the Statements are effective for 1996. The Corporation does not
expect the adoption of either of these pronouncements to have a material impact
on the financial statements.


3. RESERVE BALANCE REQUIREMENTS
   
    The Security Banc Corporation's banking subsidiary is required to maintain
certain daily cash and due from banks reserve balances in accordance with
regulatory requirements. The balances maintained under such requirements were
$8,909,000 at December 31, 1995 and $8,241,000 at December 31, 1994.



4. INVESTMENT SECURITIES

    The following table lists the book value and market value of debt
securitites and other investments as of December 31.

11. STOCK OPTIONS

    Shareholders of Security Banc Corporation approved adoption of the Security
Banc Corporation 1987 and 1995 Stock Option Plans. The plans provide for the
grant to certain key managerial personnel options to purchase shares of common
stock at the stock's fair value at the date of grant. The aggregate number of
common shares of the Corporation which may be issued under the plans are two
hundred forty thousand (240,000) shares.

    As of December 31, 1995 and 1994, there were 176,480 incentive stock
options granted with weighted average per share exercise price of $10.06. As of
December 31, 1995 and 1994 there were 74,446 and 79,796 incentive stock options
outstanding. Per the plan agreement, stock options available to be exercised as
of December 31, 1995 are 69,846 shares (72,756 shares at December 31, 1994).
During 1995, 5,350 incentive options were exercised at $58,000. When options
are exercised, the excess of the options prices over par value is credited to
surplus. During 1994, 33,664 incentive options were exercised at $308,000.



12.  DIVIDEND RESTRICTION

    The payment of dividends is subject to various regulatory restrictions. As
of December 31, 1995, approximately $22,440,000 of retained earnings was
available for the payment of dividends.



13.  RETIREMENT PLANS

    Security Banc Corporation has a non-contributory defined benefit pension
plan that covers all employees who have reached the age of twenty-one (21) and
have one thousand (1,000) hours of service during their anniversary year. The
amount of the benefit is determined pursuant to a formula contained in the
retirement plan which, among other things, takes into account the employee's
average earnings in the highest sixty (60) consecutive calendar months. Accrued
benefits are fully vested after five (5) years of service. Security Banc
Corporation's funding policy is to make annual contributions to the plan which
at least equals the minimum required contributions.

    Disclosure of net periodic Pension cost for 1995, 1994, and 1993 is as

14. COMMITMENTS AND CONTINGENT LIABILITIES

    Security Banc Corporation has various commitments and contingent
liabilities outstanding, such as letters of credit and loan commitments, that
are not reflected in the consolidated financial statements. Letters of credit
commit the Corporation to make payments on behalf of customers when certain
specified future events occur. Loan commitments are made to accommodate the
financial needs of Security Banc Corporation's customers. These arrangements
have credit risk essentially the same as that involved in extending loans to
customers and are subject to Security Banc Corporation's normal credit
policies. Collateral is obtained based on Management's credit assessment of the
customer.

    Unfunded loan commitments and unused lines of credit as of December 31,
1995 were $82,339,000. The aggregate amount of outstanding letters of credit
was $2,562,000 at December 31, 1995. No significant losses are anticipated as a
result of these commitments.

16. LOAN FEES AND RELATED COSTS

    Loan origination and commitment fees received in excess of direct costs

the loan. As of December 31, 1995, and 1994, Security Banc Corporation had
unamortized loan fees of $392,000 and $476,000, respectively.

17. 401(K) PROFIT SHARING SAVINGS PLAN

    All employees of Security National Bank become eligible participants in the
plan when they have completed one (1) year of eligibility service; have worked
at least five hundred (500) hours and are at least age twenty-one (21).
Eligible participants may make contributions to the plan by deferring up to
fifteen percent (15%) of their annual earnings.

    The Board of Directors of Security National Bank annually determine the
bank's matching contribution to the plan. For the plan year ended December
31,1995 and December 31, 1994, the matching contribution was fifty percent
(50%) of the employee's contribution up to the first six percent (6%) of annual
earnings contributed by the participant. The contribution by the bank for
1995,1994, and 1993 was $110,000, $105,000, and $101,000, respectively.

    Employee contributions are one hundred percent (100%) vested immediately.
The bank's matching contributions are vested at twenty percent (20%) for each
year of eligibility service, based on five (5) year vesting schedule.



18. FAIR VALUES OF FINANCIAL INSTRUMENTS

    FASB Statement No. 107, "Disclosures about Fair Value of Financial
Instruments," requires disclosure of fair value information about financial
instruments, whether or not recognized in the statement of condition, for which
it is practicable to estimate that value. In cases where quoted market prices
are not available, fair values are based on estimates using present value or
other valuation techniques. Those techniques are significantly affected by the
assumptions used, including the discount rate and estimates of future cash
flows. In that regard, the derived fair value estimates cannot be substantiated
by comparison to independent markets and, in many cases, could not be realized
in immediate settlement of the instrument. Statement 107 excludes certain
financial instruments and all nonfinancial instruments from its disclosure
requirements. Accordingly, the aggregate fair value amounts presented do not
represent the underlying value of the bank.

    The estimated fair values of the bank's financial instruments not disclosed
elsewhere are as follows:

                              FINANCIAL STATEMENTS

                                   (UNAUDITED)


NOTE A - PREPARATION OF FINANCIAL STATEMENTS

In the opinion of management, the accompanying unaudited financial statements
contain all adjustments consisting of normal re-occurring items necessary to
present fairly the financial condition of the company as of March 31, l996 and
the results of operations and cash flows for the three month periods ended March
31, 1996 and March 31, 1995.

NOTE B - TAXES

The effective tax rate of 29% is considerably lower than the statutory 35%
because of investments made in tax exempt municipal securities. Security
National Bank has approximately $24,300,000.00 invested in tax exempt municipal
securities.

                            SECURITY BANC CORPORATION

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

The following is management's discussion and analysis of certain significant
factors which have affected the Registrant's financial condition and results of
operations during the periods included in the consolidated financial statements
enclosed with this filing.

RESULTS OF OPERATIONS

Net income was $2,846,000 for the first three months of 1996, compared to
$2,572,000 for the same period in l995. Earnings per share were $.56 for the
first three months, a 10% increase over last year's $.51.

Total assets were $542,012,000 at March 31, l996 compared to l995's assets of
$510,519,000. For the first three months of l996, return on average equity was
15.41% and return on average assets was 2.13%.

Net interest income on a fully taxable equivalent basis for the first three
months of l996 was $6,436,000 compared to the $6,462,000 realized in the same
period of l995. This decrease resulted from a 5% increase in average earning
assets and a decrease of 29 basis points in the net interest margin.

The allowance for loan losses was $3,828,000 in the first three months of l996
and $3,715,000 in the first three months of l995. The allowance for losses as a
percent of loans and leases outstanding was 1.20% at March 31, l996 and l.17% at
March 31, 1995.

Beginning in 1995, the Company adopted Financial Accounting Standards Board
Statement No. 114, "Accounting by Creditors for Impairment of a Loan". Under the
new standard, the 1995 allowance for credit losses related to loans that are
identified for evaluation in accordance with Statement 114 is based on
discounted cash flows using the loan's initial effective interest rate or the
fair value of the collateral for certain collateral dependent loans. Prior to
1995, the allowance for credit losses related to these loans was based on
undiscounted cash flows or the fair value of the collateral for collateral
dependent loans. The following table presents data concerning loans at risk at
the end of each period.

Total other operating income was $1,438,000 and $1,008,000 during the first
three months of 1996 and 1995 respectively. There was a 3% decrease in service
charges on deposits, and a 32% increase in other charges, rents and fees. Total
securities gains for the first three months of 1996 were $358,000 or $232,700

the similar period of l995. Salaries, wages and employee benefits increased
7% over 1995. Equipment and net occupancy expenses during the first three
months were $400,000 and $335,000 for 1996 and 1995 respectively, which

                              FOR IMMEDIATE RELEASE

Security Banc Corporation, Springfield, Ohio and Third Financial Corp., Piqua,
Ohio, jointly announced today the signing of a definitive agreement in which
Third Financial Corp. will be merged into Security Banc Corporation. Following
the closing of the merger, The Third Savings and Loan Company, a subsidiary of
Third Financial Corporation, will be operated as a separate subsidiary of
Security Banc Corporation.

Under the terms of the agreement, Third Financial Corporation shareholders will
receive $33.23 at closing for each of the 1,135,954 shares outstanding. Holders
of Third's 105,476 options will receive cash equal to the offer price less the
applicable strike price. The aggregate transaction value is approximately $40
million. With this acquisition, Security will expand into Miami County, where
Third has four branches.

Harry O. Egger, President, Chairman and Chief Executive Officer of Security
said, "We are pleased that Third Savings is joining our organization. We are
excited about extending our banking market into Miami County and the
opportunities that exist to grow further Third's market areas. More importantly,
the philosophy of our two community organizations is to provide the best
personalized financial services to all of our communities and customers. The
communities of Piqua, Troy, and Tipp city, which are currently being served by
Third, will continue to play a prominent part in the future of our
organization." These offices will continue to be branches of Third Savings.

Kenneth F. Rupp, President and Chief Executive Officer of Third Financial Corp.
said, "In order to best represent the interests of all of our shareholders, the
many communities as well as the staff, the Directors evaluated our ownership
options. When it became apparent that the advantages of formulating a
transaction with Security Banc Corporation clearly outweighed the long term
prospects of total independence, the Directors agreed that the transaction was
very desirable. Third Savings will operate autonomously as a subsidiary of
Security Banc Corporation."

continuation of the successful operation of Third Savings and an improved
customer service capability for its clientele.
