1)Performance Share Units. A PSU is a hypothetical share of Simmons common stock. The value of a PSU on any given date shall be equal to the Fair Market Value of a Share on such date. Until it is paid, a PSU does not represent an equity (or any other) interest in Simmons and carries no voting or dividend rights.

2)Continuous Employment Requirement. Pursuant to the Award Certificate, the Participant has been granted PSUs in the Target Amount. These PSUs shall be converted to Company Shares in accordance with Section 3 of the Performance Share Unit Terms and Conditions (“Terms and Conditions”) only if the Participant is continuously employed by the Company from the Grant Date until the PSU attainment has been certified by the Administrator at the first regularly scheduled meeting following the date final financial results are available (“Certification Date”), except as otherwise provided in Section 5 of the Terms and Conditions (“Early Cancellation/Waiver of Continuous Employment Requirement”).

For purposes of this Section 2, the Participant shall not be treated as having experienced a termination if he or she is on an authorized leave of absence with the Company.

i.Number of PSUs Awarded. Subject to Section 4 of the Terms and Conditions, if the Participant satisfies the continuous employment requirement in Section 2 of the Terms and Conditions, on the Certification Date the Participant shall be awarded Shares equal to the number of PSUs of the Target Grant (set forth in the Award Certificate) multiplied by the Final Payout Percentage (“Final Award”).

The Final Payout Percentage shall be calculated by multiplying the Payout Percentage for Core EPS by .7 and the Payout Percentage for TSR by .3 and then adding together the resulting numbers represented as a percentage. Notwithstanding anything to the contrary, in no event shall the number of Shares earned exceed 200% of the Participant’s Target Grant.

(i)Payout Percentage for Core EPS. For purposes of determining the Payout Percentage for Core EPS, attainment calculations under the Core EPS portion of the Core EPS and Relative TSR Table (“Table”) set forth in the Award Certificate shall be performed according the following:

(ii)Payout Percentage for TSR. For purposes of determining the Payout Percentage for TSR, attainment calculations under the TSR portion of the Table set forth in the Award Certificate shall be performed according to the following:

•The TSR percentile rank attained shall be based on Simmons’ TSR for the Performance Period compared to other US banks contained in the KBW Regional Banking Index (KRXTR) on the last day of the Performance Period (“Index Banks”).

•The TSR calculation shall be based on an average of the first twenty (20) and final twenty (20) trading days in the Performance Period for the computation of both Simmons TSR and the TSR for Index Banks. The daily TSR computations shall be determined by the Administrator’s designee according to its standard TSR methodology.

•In between “Threshold” to “Target,” and “Target” to “Maximum,” the Payout Percentage is a sliding scale based on a straight line interpolation.

4)Discretion to Reduce or Increase Award. The Administrator reserves the right to adjust the amount payable under the Award Certificate in accordance with any standard or on any other basis as the Administrator may determine including individual performance or the Administrator’s discretion.

iii.Retirement. If the Participant retires, the Participant shall be awarded PSUs for the Performance Period as if the Participant had satisfied the continuous employment requirement set forth in Section 2 of the Terms and Conditions, and unless otherwise provided by the Administrator, such PSUs shall be multiplied by a fraction, the numerator of which is the number of days in the Performance Period completed by the Participant as of the date of the retirement and the denominator of which is the number of years in the Performance Period multiplied by 365.

All PSUs for which the continuous employment requirement is waived pursuant to this Section 5)b) shall be payable at the time the PSUs would have been payable had the Participant been subject to and satisfied the continuous employment requirement set forth in Section 2 of the Terms and Conditions; payment will not be accelerated.
