Standards No. 115; (ii) NIBT shall be determined after subtracting the sum of
any amount paid to or for the benefit of Employee hereunder and all other
bonuses and compensation paid to the Bank's employees for such period and (iii)
in the event CNB achieves at least 85% of its NIBT Target, then Employee will
receive 55% of the corresponding Cash Bonus and ESOP contribution above, with
that amount increasing by 3% for every 1% that NIBT increases until NIBT exceeds
115% of budget where upon CNB's Compensation Committee will determine the
incentive paid for the performance above that level.

Agreement payment by CNB to Employee as termination compensation in an amount

term life insurance; (ii) CNB without Cause during the term of this Agreement,
in the event of a Change in Control of CNB, one year of existing base salary for
payment by CNB to Employee as termination compensation ("Change of Control" of
CNB means any transaction, whether by merger, consolidation, asset sale, tender
offer, reverse stock split or otherwise, which results in the acquisition of
beneficial ownership (as such term is defined under the rules and regulations
promulgated under the Securities Exchange Act of 1934, as amended) by any person
or entity or any group of persons or entities acting in concert, of 50% or more
of the outstanding shares of common stock of CNB; provided, however, that the
execution and consummation of any merger transaction by and between First
Capital Bancorp, Inc. and CNB shall be excluded from this definition of Change
of Control); or (iii) CNB with Cause or in the event CNB or the Bank are taken
over by bank regulatory authorities, no termination compensation to Employee.
