PART I

ITEM 1.      BUSINESS

        Security Banc Corp. (Registrant or Company) was organized in 1985 under
        the laws of The State of Ohio. The Executive Office of the registrant is
        located in Springfield, Ohio. It is a Bank Holding Company as defined in
        the Bank Holding Company Act of 1956, as amended, and is registered as
        such with the Board of Governors of the Federal Reserve System.
        Registrant has three subsidiaries, The Security National Bank and Trust
        Co. (Security), Citizens National Bank (Citizens), and Third Savings and
        Loan Company, (Third).

        The Security National Bank and Trust Co. was organized under the
        statutes of The United States as the result of an agreement to merge The
        Guardian Bank of Springfield, Ohio, with and into The New Carlisle
        National Bank under the title of The Security National Bank. The
        agreement to merge was finalized and given approval by the Office of The
        Comptroller of the Currency on October 1, 1969. The Bank was granted the
        authority to act as a fiduciary as of May 30, 1978, thereby, changing
        the name of the Association to "The Security National Bank and Trust
        Co." The Bank's main office is located at 40 South Limestone Street,
        Springfield, Ohio.

        On September 30, 1996, the Company merged with CitNat Bancorp, Inc., a
        $140 million bank holding company headquartered in Ohio, in a
        transaction accounted for as a pooling of interest.

        On October 21, 1996, the Company acquired all of the outstanding shares
        of Third Financial Corporation for $41 million. The acquisition was
        accounted for using the purchase method of accounting.

        Security and Citizens are subject to primary supervision, examination,
        and regulation by The Comptroller of the Currency. Third is subject to
        primary supervision, examination, and regulation by The Office of Thrift
        Supervision. Security and Citizens are members of The Federal Reserve
        System and are subject to the applicable provisions of The Federal
        Reserve System and are subject to the applicable provisions of the
        Federal Reserve Act and Regulations. Deposits of the Company are insured
        by The Federal Deposit Insurance Corporation (FDIC) to the maximum
        extent permitted by law.

        Security was the parent of the Security Community Urban Redevelopment
        Corporation. The subsidiary was an Ohio Corporation organized in 1975
        and dissolved in 1997. It was organized solely to own Security's main
        office building. Presently, Security owns the Main Office building.

        All of the Company's banking centers are located in Champaign, Clark,
        Fayette, Greene, Madison and Miami Counties in the state of Ohio.

BUSINESS--CONTINUED

As of December 31, 1998, the Company's consolidated total assets rounded to the
nearest thousand, were $883,500,000 including total loans of $562,005,000. On
that date, total deposits were $708,853,000 and capital accounts totaled
$118,129,000.

The Company's subsidiaries provide full service banking to individuals as well
as to industry and governmental subdivisions through each of its twenty-four
banking centers.

The Company's subsidiaries have made a strong impact on all the counties it
serves through a great variety of services, including personal checking accounts
and savings programs, certificates of deposit, the Money Market accounts, C/D's
and Individual Retirement Accounts.

A broad range of credit programs for all retail customers includes mortgage
loans, credit card banking under the VISA designation, installment loans, and
secured and unsecured personal loans.

The banking services provided to commercial customers and government include
maintenance of demand and time deposit accounts and certificates of deposit.
Available are all types of commercial loans, including loans under lines of
credit and revolving credit, term loans, real estate mortgage loans and other
specialized loans including accounts receivable financing. The Subsidiaries
further serve the requirements of large and small industrial and commercial
enterprises in the Springfield metropolitan area and elsewhere by providing
financial counseling, automated payroll programs, cash management, and other
automated services.

The subsidiaries' Commercial Banking Division is organized to serve the needs of
the corporate customers by handling business and commercial mortgages, corporate
deposits and other corporate financial services.

The Consumer Banking Divisions, which encompasses the Credit Card and
Installment Loan Departments, serves individual as well as corporate customers.
The Residential Mortgage Loan Departments provides conventional as well as
adjustable rate mortgage loans to individuals. Each Subsidiary manages the
investment of funds for their institution using U. S. Government and agency
securities, municipal (tax exempt) securities, as well as Federal Funds and
certificates of deposit of U. S. banks and savings and loans. Each Subsidiary,
in consultation with others, sets the rates on their liability products
including purchased federal funds.

Complete fiduciary services are available to individuals, charitable
institutions, commercial customers and government agencies through Security's
Trust Division. The Personal Trust Department serves as investment agent and
custodian for securities portfolios of individuals, as trustees for living and
testamentary trusts and as executor and administrator of probate estates. The
Corporate Trust Department serves as Trustee for corporate and municipal bond
issues, and as registrar for securities. The Institutional Services Department
provides employee benefit plan fund management for qualified retirement plans
and investment management and securities custody services for not-for-profit
institutions.

There are over a half dozen commercial banks in Springfield, Clark County and
adjoining counties, furnishing general banking services and thus providing
strong competition to the Company. The Company competes for deposits not only
with commercial banks in its area, but also with building and loan associations
and other non-bank competitors, such as brokerage houses. In addition to the
competition described above, the Company competes in various areas of service
offered to individuals, industry and government with Banks in Southwestern Ohio,
many of which possess greater financial resources than the Company.

                                       -4-

BUSINESS--CONTINUED

The earnings of the Company are affected by general economic conditions as well
as, by the monetary policies of the Federal Reserve Board. Such policies, which
have the effect of regulating the national supply of Bank reserves and Bank
credit, can have a major affect upon the source and cost of loanable and
investable funds and the rates of return earned on loans and investments. Among
the means available to the monetary authorities to influence the size and
distribution of Bank reserves are open market operations by the Board of
Governors of the Federal Reserve System, changes in cash reserve requirements
against member bank deposits, and limitations on interest rates which member
banks may pay on most time and savings deposits.

Material Changes and Developments
- ---------------------------------

There were no material changes or developments during 1998 in the business done
by the Company.

Regulation and Supervision
- --------------------------

Security and Citizens, as national banks, are subject to regulation by the
Comptroller of the Currency, The Board of Governors of the Federal Reserve
System and The Federal Deposit Insurance Corporation. Third, as a savings and
loan, is subject to regulation by the Office of Thrift Supervision and The
Savings Association Insurance Fund. The Company and any subsidiaries which it
may hereafter have will be affiliates of the Company within the meaning of the
Federal Reserve Act. As affiliates, the Company and any such subsidiaries are
subject to certain restrictions on loans by the subsidiaries, on investments by
the subsidiaries in their stock or securities or on its taking such stock and
securities as collateral for loans to any borrower. The Company and any such
subsidiaries, as affiliates of the Company are also subject to certain
restrictions with respect to engaging in the underwriting and public sale and
distribution of securities. Neither the Company nor any such subsidiaries may,
for example, engage in such transactions with respect to securities of the
company unless such securities are registered under the Securities Act of 1993
or any exemption from such registration is available. In addition, any such
affiliates of the Bank will be subject to examination at the discretion of
supervisory authorities.

The Company, as a Bank Holding Company, is subject to the restrictions of the
Bank Holding Company Act of 1956 as amended. This Act first provides that the
acquisition of control of a bank is subject to the prior approval of the Board
of Governors of the Federal Reserve System. In the future, the Company will be
required to obtain the prior approval of the Federal Reserve Board before it may
acquire, for its individual account all, or substantially all, of the assets of
any bank, or acquire ownership or control of any voting securities of any Bank,
if after giving effect to such acquisition, the Company would own or control
more than 5% of the voting shares of such bank. The Act does not permit the
Federal Reserve Board to approve the acquisition by the Company or any
subsidiary for their own account, of any voting shares of, or interest in, or
all, or substantially all, of the assets, of any bank located in a state other
than Ohio, unless such acquisition is specifically authorized by the statutes of
the state in which such bank is located.

The Bank Holding Company Act limits the activities which may be engaged in by
the Company and its subsidiaries to ownership of banks and those activities
which the Federal Reserve Board has deemed or may in the future find, by order
of regulations, to be so closely related to the banking or managing or
controlling banks as to be a proper incident thereto.

RISK ELEMENTS
- -------------

Interest on loans is normally accrued at the rate agreed upon at the time each
loan was negotiated. It is the Bank's policy to discontinue accrual of interest
on commercial and mortgage loans when there is a clear indication that the
borrower's cash flow may not be sufficient to meet payments as they become due.
When a consumer loan is uncollectable, the loan is charged off. If there is
collateral, it is secured and disposed of. In regards to paragraph 6i of SFAS
118, the amounts are immaterial and, therefore, not disclosed. The following
table presents data concerning loans at risk at the end of each period. (000s).

Allowance for Loan Losses
- -------------------------

The allowance for loan losses is established through charges to operations by a
provision for loan losses. Loans which are determined to be uncollectible are
charged against the allowance and subsequent recoveries, if any, are credited to
the allowance. The amount charged to operations is based on several factors.
These include the following:

        1.      Analytical reviews of the loan loss experience in relationship
                to outstanding loans to determine an adequate allowance for loan
                losses required for loans at risk.

        2.      A continuing review of problem or at risk loans and the overall
                portfolio quality.

        3.      Regular examinations and appraisals of the loan portfolio
                conducted by the Bank's examination staff and the banking
                supervisory authorities.

        4.      Management's judgement with respect to the current and expected
                economic conditions and their impact on the existing loan
                portfolio.

The amount provided for loan losses exceeded actual net charge-offs by $629,000
in 1998 and $206,000 in 1996. Net charge-offs exceeded the amount provided for
loan losses by $573,000 in 1997.

It is management's practice to review the allowance on a quarterly basis to
determine whether additional provisions should be made after considering the
factors noted above. Based on these procedures, management is of the opinion
that the allowance at December 31, 1998 of $6,883,000 is adequate.

Loan Commitments and Standby Letters of Credit
- ----------------------------------------------

Loan commitments are made to accommodate the financial needs of our customers.
Letters of credit commit the Company to make payments on behalf of customers
when specific future events occur.

Both arrangements have credit risk essentially the same as that involved in
extending loans to customers and are subject to the Company's normal credit
policies. Collateral (e.g., securities, receivables, inventory, equipment) is
obtained based on Management's credit assessment of the customer.
