Explanation of Responses:

( 1 )These shares are subject to performance stock units (the "PSUs"). The PSUs have a service-based vesting component as well as performance vesting requirement. Under the service-based vesting component, the PSUs vest 100% after three years subject to the reporting person's continued employment with Synovus. Under the performance vesting component, two performance measures (weighted average return on tangible common equity and relative total shareholder return) are measured over a three-year performance period, with each measure impacting one-half of the PSUs awarded to the reporting person. 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. ( 2 )These shares are subject to performance stock units ("Additional PSUs") and have the same service-based and performance-based vesting components as the PSUs reported above. In addition, the Additional PSUs require a minimum of one year of service to be eligible for retirement vesting. ( 3 )These shares are subject to restricted stock units that will be settled in cash upon vesting. The units vest 1/3 each year over a three-year period subject to the reporting person's continued employment with Synovus.
