F1: On March 19, 2012, the Compensaton and Benefits Committee of the Registrant's board of directors approved the grant of restricted stock under the S&T Bancorp, Inc. 2003 Incentive Stock Plan for an incentive under the S&T Bancorp, Inc. Long Term Incentive Plan. The actual number of shares granted and communicated to the Reporting Person was determined based on the target incentive payout, which is 20% of the Reporting Person's base salary on the grant date divided by the average of the high and low prices of S&T Bancorp, Inc. common stock on the grant date. One half of the shares will be earned based on remaining with S&T for three years. The other half will be earned based on S&T's Return on Average Equity performance over a three year period.
