Note 1, Basis of Presentation

         On April 13, 1998, shareholders of The Commercial Bank (the "Bank")
approved a Merger Agreement ("Agreement") pursuant to which ComBanc, Inc. (the
"Company") acquired all of the outstanding stock of the Bank as a result of the
exchange of shares between the shareholders of the Bank and the Company. After
the share exchange which became effective on August 31, 1998, the Bank survived
as a wholly-owned subsidiary of the Company and continues its operations as The
Commercial Bank. Under the terms of the Agreement, each one of the existing
outstanding shares of the Bank's common stock was exchanged for two of the
Company's common shares so that each existing shareholder of the Bank became a
shareholder of the Company, owning the same number and percentage of shares in
the Company as the Bank. The shares of the Company issued in connection with the
transaction were not registered under the Securities Act of 1933, as amended
(the "Act"), in reliance upon the exemption from registration set forth in
Section 3(a) (12) of the Act.

         As a result of the transaction described above, the Company is the
successor issuer to the Bank pursuant to Rule 12g-3 promulgated under the
Securities Exchange Act of 1934 (the "Exchange Act"). The Bank is subject to the
informational requirements of the Exchange Act and in accordance with Section
12(I) thereof has timely filed reports and other information with the Board of
Governors of the Federal Reserve System ("FRS"). Such reports and other
information filed by the Bank with the FRS may be examined without charge at, or
copies obtained upon payment of prescribed fees from, the Securities Disclosure
Division, Board of Governors of the Federal Reserve System, Stop 153A,
Washington, D.C. 20551.

         The accompanying unaudited condensed consolidated financial statements
have been prepared in accordance with generally accepted accounting principles
for interim financial information and with the instructions to Form 10-Q.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.

         For further information, refer to the consolidated financial statements
and footnotes included in the Company's annual report for the year ended
December 31, 1998.


Note 2, Earnings per Share

         Earnings per share on the 1998 income statements have been restated to
reflect the total outstanding shares as of the August 31, 1998 formation of
ComBanc, Inc. Both basic and diluted earnings per share are computed based on
the same weighted-average number of shares outstanding.

Item 2 - Management's Discussion and Analysis of Financial Condition and Results
of Operations

ENTITY STATUS

          On April 13, 1998, The Commercial Bank became a wholly-owned
subsidiary of the newly formed ComBanc, Inc., a one-bank holding company. Since
ComBanc's only significant asset is the investment in The Commercial Bank, the
following discussion will focus solely on the operations of The Commercial Bank.

MATERIAL CHANGES IN FINANCIAL CONDITION

          Loans increased $15 million from December 31, 1998 to $157 million at
September 30, 1999; an annualized rate of 14%. Most of the increase was in
commercial and real estate lending.

          Net unrealized depreciation on securities was $264 thousand at
September 30, 1999, a decrease in market value of $700 thousand since December
31, 1998, reflecting the downward market movement.

          Other borrowed money, mainly funds from the Federal Home Loan Bank,
increased by $15 million from December 31, 1998, to $18 million at September 30,
1999. Such borrowings were used to fund the increased loan demand.

CURRENT YEAR THIRD QUARTER VERSUS PRIOR YEAR THIRD QUARTER

          Net interest income, the difference between interest earned on
interest-earning assets and interest expense incurred on interest-bearing
liabilities, is the most significant component of The Commercial Bank's
earnings. Net interest income is affected by changes in the volume and rates of
interest-earning assets and interest-bearing liabilities and the volume of
interest-earning assets funded with low cost deposits, noninterest-bearing
deposits and shareholders' equity. The Bank's net interest income increased 7%,
to $2,100,000 for the quarter ended September 30, 1999 from $1,966,000 for the
third quarter of 1998. The Bank's net interest income increased 8% to $6,188,000
for the nine months ended September 30, 1999 from $5,737,000 for the nine months
ended September 30, 1998. These increases were due principally to the widening
of the yield/cost spread due to a slower increase in the cost of deposits
compared to the increase in earning assets.

          The provision for loan loss remained at $90,000, for the third quarter
1999 and 1998, and remained at $270,000 for the nine months ended September 30,
1999 and 1998, respectively.

          Non-interest income for the three months ended September 30, 1999
increased 64% to $210,000 from $128,000 in the third quarter of 1998.
Non-interest income increased 32%, to $441,000 from $334,000 for the nine months
ended September 30, 1999. These increases were largely attributable to an
increase in fee income as well as security gains on the sale of investments of
$52,000.00.

          Non-interest expense for the quarter increased 4%, to $1,282,000 from
$1,234,000 the previous year. Non-interest expense for the nine months ended
September 30, 1999 increased 10%, to

$3,814,000 from $3,465,000. Salaries and fringe benefits and net occupancy
increased during the quarter ended September 30, 1999 and for the nine months
ended September 30, 1999.

          Federal income taxes increased $88,000 for the quarter, to $295,000
from $207,000 for the previous year. Federal income taxes increase $117,000 to
$755,000 from $638,000 for the nine months ended September 30, 1999. These
increases were due to an overall increase in net income.

          Earnings per share increased 17% to $.27 from $.23 for the quarter.
Earnings per share increased to $.75 from $.72 for the nine months ended
September 30, 1999 and 1998. Per share earnings are computed based on 2,371,182
weighted-average number of shares outstanding for the third quarter 1999,
2,373,972 shares outstanding for the nine months ended September 30, 1999, and
2,376,000 shares outstanding for both periods ending in 1998.

REGULATORY CAPITAL

The Federal Reserve Board's risk-based capital guidelines addressing the capital
adequacy of bank holding companies and banks (collectively, "banking
organizations") include a definition of capital and a framework for calculating
risk-weighted assets and off-balance sheet items to broad risk categories, as
well as minimum ratios to be maintained by banking organizations. A banking
organization's risk-based capital ratios are calculated by dividing its
qualifying capital by its risk-weighted assets.

        Under the risk-based capital guidelines, there are two categories of
capital: core capital ("Tier 1") and supplemental capital ("Tier 2"),
collectively referred to as Total Capital. Tier 1 Capital includes common
stockholders' equity, qualifying perpetual preferred stock and minority interest
in equity accounts of consolidated subsidiaries. Tier 2 capital includes
perpetual preferred stock (to the extent ineligible for Tier 1), hybrid capital
instruments (i.e. perpetual debt and mandatory convertible securities) and
limited amounts of subordinated debt, intermediate-term preferred stock and the
allowance for credit losses.

        The Federal Reserve Board's leverage constraint guidelines establish a
minimum ratio of Tier 1 Capital to quarterly average total assets ("Leverage
Ratio").

        The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") established five capital tiers for banks. Pursuant to that statute
the federal bank regulatory agencies have defined the five capital tiers for
banks. Under these regulations, a bank is defined to be well capitalized, the
highest tier, if it maintains a Tier 1 Capital ratio of at least 6 percent, a
Total Capital ratio of at least 10 percent and a Leverage Ratio of at least 5
percent.

        Based on the respective regulatory capital ratios at September 30, 1999,
the Bank is well capitalized, based on the definitions in the regulations issued
by the Federal Reserve Board and the other federal bank regulatory agencies
setting forth the general capital requirements mandated by FDICIA.


LIQUIDITY

        The liquidity of a banking institution reflects its ability to provide
funds to meet loan requests, to accommodate possible outflows in deposits and to
take advantage of interest rate market opportunities. Funding of loan requests,
providing for liability outflows, and management of interest rate fluctuations
require continuous analysis in order to match the maturities of specific
categories of short-term loans and investments with specific types of deposits
and borrowings. Bank liquidity is thus normally considered in terms of the
nature and mix of the banking institution's sources and uses of funds.

        Liquid assets consist of cash and due from banks, federal funds sold,
and securities available for sale. At September 30, 1999 the Bank's liquid
assets amounted to $49,584,000 or 24% of total assets compared with 26% at
December 31, 1998.

        Management considers its liquidity to be adequate to meet its normal
funding requirements.

YEAR 2000 SOFTWARE INITIATIVE

         Management has initiated a bank-wide assessment, remediation and
conversion program to address the effect of the year 2000 on the Corporation's
information systems and application software. The Corporation's Year 2000
project contains assessment, renovation, validation and implementation phrases.
A substantial majority of the significant application software utilized by the
Corporation is via the use of third party data processors and management is
working with the vendors to ensure that the software will operate properly in
the year 2000. At this time, the estimated cost to remediate the Bank's year
2000 issues is not expected to be material.

         A contingency plan has been established for critical business system
application to mitigate potential problems/delays associated with either new
system replacements or established vendor delivery dates.

         The corporation, however, continues to bear some risk related to the
Year 2000 issue and could be adversely affected, if other entities (i.e.,
vendors) not affiliated with the Corporation do not appropriately address their
own Year 2000 compliance issues.

Item 1 - Legal Proceedings

        The Commercial Bank, at any given time, is involved in a number of
lawsuits initiated by The Commercial Bank as a plaintiff, intending to collect
upon delinquent accounts, to foreclose upon real property, or to seize and sell
personal property pledged as security for any such account. Combanc, Inc. is
involved in no legal proceedings.

        At September 30, 1999, The Commercial Bank was involved in a number of
such cases as a party-plaintiff, and occasionally, as a party-defendant due to
its joinder as a lien holder, either by mortgage or by judgment lien. In the
ordinary case, The Commercial Bank's security and value of its lien is not
threatened, except through bankruptcy or loss of value of the collateral should
sale result in insufficient proceeds to satisfy the judgment.

        Management and the Board are not aware of any additional potential
claims against the Bank which have not been disclosed herein.
