Under the service-based vesting component, the PSUs vest 100% after three years subject to the reporting person's continued employment with Synovus.

The actual payout of the PSUs may range from 0% to 150% of the target amount based upon the results of the two performance measures during the performance period compared to the performance objectives approved by the Compensation Committee of the Synovus' Board of Directors.
