financial performance information is as follows:

Balance Sheet:

      o     Total Federal Funds, Interest Bearing Deposits in Banks and
            Investment Securities: $66,926,000, an increase of $42,682,000 or
            176.05%.

      o     Net Loans: $308,092,000, an increase of $27,591,000 or 9.84%.

      o     Total Assets: $421,122,000, an increase of $78,314,000 or 22.84%.

      o     Non-Interest Bearing Deposits: $60,940,000, a decrease of $2,210,000
            or 3.5%.

      o     Total Deposits: $365,479,000, an increase of $65,630,000 or 21.89%.

      o     Total Shareholders Equity: $33,677,000, an increase of $7,279,000 or
            27.57%.

Income Statement:

      o     Total Interest Income: $7,937,000, an increase of $995,000 or
            14.33%.



      o     Total Interest Expense: $3,696,000, an increase of $1,217,000 or
            49.09%.

      o     Net Interest Income: $4,241,000, a decrease of $222,000 or 4.97%.

      o     Non-Interest Income: $589,000, a decrease of $129,000 or 17.94%.

      o     Non-Interest Expense: $2,711,000, an increase of $109,000 or 4.19%.
            As of September 30, 2007 the Company had 86 full-time employees as
            compared to 80 as of September 30, 2006.

      o     Net Income: $1,301,000, a decrease of $211,000 or 13.96%.

      o     Net Interest Margin: 4.48%, down 131 basis points. The decrease is
            due primarily to reduction in loan fees recorded in the third
            quarter. Other factors affecting the decrease in net interest margin
            were increases in the rates paid on deposits and the growth of
            interest bearing deposits, particularly time deposits. The change in
            mix was offset somewhat by the increases in the overall yields on
            earning assets and the change in mix of earning assets with more
            loans and Federal funds sold.

            During the third quarter, management also updated the cost model for
            deferred loan fees and direct costs associated with making loans,
            commitments to lend and purchases of loans. The most significant
            change was an increase in the amount of deferred costs associated
            with short term loans (less than twelve months).

      o     Annualized Return on Average Assets: 1.26% down from 1.77%.

      o     Annualized Return on Average Equity: 15.99% down from 23.93% The
            decrease in ROE is attributable to the decrease in earnings of
            $211,000 or 13.96% for the quarter ended September 30, 2007 from the
            quarter ended September 30, 2006, offset by an increase in
            shareholders equity from net income and the proceeds from the
            exercising of options. The increase in equity totaled $7,279,000 or
            27.57%.

      o     Efficiency Ratio: 56.13% increasing from 50.22%. The increase was
            caused by increased employee expenditure and the purchase of new
            technology to support the growth of the Company.

      o     Basic Earnings Per Share: $0.35, a decrease of $0.09 per share or
            20.45%.

      o     Diluted Earnings Per Share: $0.33, a decrease of $0.06 per share or
            15.38%.

Balance Sheet: September 30, 2007 as compared to December 31, 2006

      o     Total Fed Funds, Interest Bearing Balances in Banks and Investment
            Securities: $66,926,000, a increase of $12,189,000 or 22.27%.

      o     Net Loans: $308,092,000, an increase of $20,774,000 or 7.23%.

      o     Total Assets: $421,122,000, an increase of $34,370,000 or 8.89%.



      o     Non-Interest Bearing Deposits: $60,940,000 a decrease of $12,257,000
            or 16.75%.

      o     Total Deposits: $365,479,000, an increase of $24,483,000 or 7.18%.

      o     Total Shareholders Equity: $33,677,000, an increase of $4,618,000 or
            15.89%.

      Income Statement: For the nine-month period ended September 30, 2007
      compared to the nine-month period ended September 30, 2006:

      o     Total Interest Income: $23,575,000, an increase of $4,512,000 or
            23.67%.

      o     Total Interest Expense: $10,350,000, an increase of $4,029,000 or
            63.74%.

      o     Net Interest Income: $13,225,000, an increase of $483,000 or 3.79%.

      o     Non-Interest Income: $1,981,000, an increase of $172,000 or 9.51%.

      o     Non-Interest Expense: $8,412,000, an increase of $771,000 or 10.09%.
            As of September 30, 2007 the Company had 86 full time employees as
            compared to 80 at September 30, 2006.

      o     Net Income: $4,036,000, an increase of $10,000 or 0.25%. Net income
            was consistent with the same period in the prior year. Factors
            affecting net income include the decrease in net interest margin and
            increased operating expenses to support the growth of two new
            offices. The increased expenses were offset slightly by increases in
            non-interest income and decreases in tax expense.

      o     Net Interest Margin: 4.91%, down 93 basis points. The decrease is
            due primarily to reduction in loan fees recorded in the third
            quarter. Other factors affecting the decrease in net interest margin
            were increases in the rates paid on deposits and the growth of
            interest bearing deposits, particularly time deposits. The change in
            mix was offset somewhat by the increases in the overall yields on
            earning assets and the change in mix of earning assets with more
            loans and Federal funds sold.

            During the third quarter, management also updated the cost model for
            deferred loan fees and direct costs associated with making loans,
            commitments to lend and purchases of loans. The most significant
            change was an increase in the amount of deferred costs associated
            with short term loans (less than twelve months).

      o     Annualized Return on Average Assets: 1.36% down from 1.68%.

      o     Annualized Return on Average Equity: 17.48% down from 23.11%.

      o     Efficiency Ratio: 55.32% increasing slightly from 52.51%.

      o     Basic Earnings Per Share: $1.10, a decrease of $0.05 per share or
            4.35%.

      o     Diluted Earnings Per Share: $1.01, a decrease of $0.02 per share or
            1.94%.
