(1)	On March 16, 2015, the Compensaton and Benefits Committee of the Registrant's board of directors approved the grant of restricted stock under the S&T Bancorp, Inc. 2014 Incentive Plan for an incentive under the 2015 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 as a percentage 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 over the 10-day trading period ending 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 and Cumulative Total Shareholder Return performance over a three year period.
