Section 18. Special Provisions Relating to Supplemental Retirement Benefit of Prior Plan:
Prior to January 1, 1997, Section 4.1 of the Prior Plan provided a special supplemental retirement benefit (the Retirement Plan Supplement) to supplement the benefits
payable to Participants under the tax-qualified Southern National Corporation Pension Plan (the defined benefit plan sponsored by BB&T was formerly known as the Retirement Plan for the Employees of Branch Banking and Trust Company). The provisions of the Prior Plan relating to the Retirement Plan Supplement have been incorporated into a new non-qualified supplemental retirement plan effective as of January 1, 1997. The new non-qualified supplemental retirement plan is known as the BB&T Corporation Non-Qualified Defined Benefit Plan.
