(h)     Freeze/Conversion of CEO Benefit

Effective as of May 31, 2017, the Accrued Benefit of the Participant who is the Corporation’s Chairman, President and Chief Executive Officer as of such date (the “CEO”) shall be frozen as of such date (the “CEO Frozen Benefit”) and the value of such CEO Frozen Benefit shall be “converted” to the CEO Converted Benefit, as described below:

1. CEO Frozen Benefit. A CEO Frozen Benefit shall be computed based on Credited Service, Average Monthly Earnings, a payment date commencing at May 31, 2017, and any other applicable factors as of such date, assuming payment in the form of a single life annuity regardless of the form of payment or commencement date actually elected under this Supplemental Plan.

2. CEO Converted Benefit. The CEO Frozen Benefit shall be “converted” to a defined contribution form of benefit (an account balance) with an actuarial present value based on a payment date commencing on May 31, 2017, and actuarial assumptions in effect under this Supplemental Plan on such date (the “CEO Converted Benefit”). As soon as administratively feasible after May 31, 2017, the CEO Converted Benefit shall be credited to a Supplemental Executive Retirement Plan Account within the meaning of, and administered in accordance with, the Regions Financial Corporation Supplemental 401(k) Plan.

Notwithstanding anything herein to the contrary, effective upon the date the CEO Converted Benefit is credited to a Supplemental Executive Retirement Plan Account under the Regions Financial Corporation Supplemental 401(k) Plan, the CEO’s Accrued Benefit in this Supplemental Plan shall be reduced to $0 and the CEO shall no longer be eligible to participate in, or accrue any benefits under, this Supplemental Plan.
