2.Vesting.

(a)Vesting Schedule.

(c)Termination of Employment Due to Death or Disability. All unvested Restricted Stock Units shall immediately vest, with the performance goals set forth on Exhibit A deemed satisfied at the target level, upon a termination of Participant’s employment due to the death or Disability, subject to Participant’s (or Participant’s estate’s or guardian’s) execution and non-revocation of a release of claims in a form provided by the Company within 60 days following Participant’s termination of employment (or any longer period required by applicable law).

Except as provided in Section 2(c) or 2(d) in the event of Participant’s termination of employment by the Company or by Participant for any other reason whatsoever, the unvested portion of the Restricted Stock Units held by Participant at that time shall immediately be forfeited and canceled.

4.Issuance and Transferability.

(a)Issuance of Common Stock. Within 60 days following the vesting of any Restricted Stock Unit in accordance with Section 2, the Company shall issue to Participant one Share for each vested Restricted Stock Unit. To the extent a Restricted Stock Unit does not vest in accordance with the provisions of this Agreement, such Restricted Stock Unit shall be forfeited and no Shares shall be issued with respect to such forfeited Restricted Stock Unit.

(b)Prohibition on Transfer. The Restricted Stock Units shall not be transferable. No right or benefit hereunder shall in any manner be liable for or subject to any debts, contracts, liabilities, or torts of Participant. Any purported assignment, alienation, pledge, attachment, sale, transfer or other encumbrance of the Restricted Stock Units, regardless of by whom initiated or attempted, shall be void and unenforceable against the Company. If, notwithstanding the foregoing, an assignment, alienation, pledge, attachment, sale, transfer or other encumbrance of the Restricted Stock Units is effected by operation of law, court order or otherwise, the affected Restricted Stock Units shall remain subject to the risk of forfeiture, vesting requirement and all other terms and conditions of this Restricted Stock Unit Agreement. In the case of Participant’s death or Disability, Participant’s vested rights under this Restricted Stock Unit Agreement (if any) may be exercised and enforced by Participant’s guardian or legal representative.

5.Dividend Equivalents. In the event that the Company declares a cash dividend on its Common Stock having a record date on or after the Grant Date and prior to the date the vested Restricted Stock Units are settled, subject to any reservations, conditions or restrictions set forth in this Restricted Stock Unit Agreement and/or the Plan, Participant shall be entitled to Dividend Equivalents equal to the per Share cash dividend(s) multiplied by the number of Shares earned and payable under the Restricted Stock Units granted to Participant under this Restricted Stock Unit Agreement, if any. Such Dividend Equivalents shall be accrued on Participant’s behalf and paid in cash to Participant at the same time, and otherwise under the same terms and conditions (including satisfaction of all vesting requirements) as apply to the corresponding Restricted Stock Units. In the event of the forfeiture of the Restricted Stock Units granted under this Restricted Stock Unit Agreement, the Participant shall have no further rights with respect to the corresponding Dividend Equivalents.

6.Reorganization of the Company. The existence of this Restricted Stock Unit Agreement shall not affect in any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company’s capital structure or its business; any merger or consolidation of the Company; any issue of bonds, debentures, preferred or prior preference stock ahead of or affecting the Restricted Stock Units or the rights thereof; the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

7.Certain Restrictions. By executing this Restricted Stock Unit Agreement, Participant acknowledges that he will enter into such written representations, warranties and agreements and execute such documents as the Company may reasonably request in order to comply with the securities law or any other applicable laws, rules or regulations, or with this Restricted Stock Unit Agreement or the terms of the Plan.

8.Amendment and Termination. This Restricted Stock Unit Agreement or the Plan may be amended or terminated in accordance with the terms of the Plan.

9.Taxes and Withholdings.

(a)Tax Consequences. The vesting and/or sale of all or any portion of the Restricted Stock Units may trigger tax liability. Participant agrees that he shall be solely responsible for any such tax liability. Participant is encouraged to contact his tax advisor to discuss any tax implications which may arise in connection with the Restricted Stock Units.

(b)Withholding. Participant acknowledges that the settlement of Restricted Stock Units and any accrued Dividend Equivalents granted pursuant to this Restricted Stock Unit Agreement may result in federal, state or local tax withholding obligations. Participant understands and acknowledges that the Company will not issue Shares or make any payment of accrued Dividend Equivalents until it is satisfied that appropriate arrangements have been made to satisfy any tax obligation under this Restricted Stock Unit Agreement or the Plan and agrees to make appropriate arrangements suitable to the Company for satisfaction of all tax withholding obligations. Further, Participant hereby agrees and grants to the Company the right to withhold from any payments or amounts of compensation, payable in cash, shares or otherwise, in order to meet any tax withholding obligations under this Restricted Stock Unit Agreement or the Plan. As such, if the Company requests that Participant take any action required to effect any action described in this Section 9 and to satisfy the tax withholding obligation pursuant to this Restricted Stock Unit Agreement and the Plan, Participant hereby agrees to promptly take any such action.

(c)Section 409A. For purposes of Section 409A of the Code (“Section 409A”), it is intended that amounts payable pursuant to this Restricted Stock Unit Agreement qualify for the short-term deferral exception under Treas. Reg. Section 1.409A-1(b)(4) or any successor thereto, and all provisions of this Award Agreement shall be construed and interpreted in a manner consistent with such exception. In the event that it is determined that any amounts payable pursuant to this Restricted Stock Unit Agreement do not qualify for the short-term deferral exception under Treas. Reg. Section 1.409A-1(b)(4) or any successor thereto, it is intended that the provisions of this Restricted Stock Unit Agreement comply with Section 409A, and all provisions of this Restricted Stock Unit Agreement shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A and any similar state or local law. Except as permitted under Section 409A, any amounts payable hereunder that constitute “nonqualified deferred compensation” (within the meaning of Section 409A) may not be reduced by, or offset against, any amount owing by Participant to the Company or any of its affiliates. To the extent required by Section 409A, any amounts payable hereunder that constitute nonqualified deferred compensation payable or provided to Participant upon a termination of employment or Change in Control, as applicable, shall only be paid or provided to Participant upon Participant’s separation from service (within the meaning of Section 409A) or an event described in Section 409A(a)(2)(v) of the Code, respectively. Notwithstanding any other provision of this Restricted Stock Unit Agreement to the contrary, if Participant is a “specified employee” (within the meaning of Section 409A, as determined in accordance with the methodology established by the Company), amounts that constitute nonqualified deferred compensation that otherwise would be payable by reason of Participant’s separation from service during the six-month period immediately following such separation from service shall instead be paid or provided on the first business day following the date that is six months following Participant’s separation from service or any earlier date permitted by Section 409A. If Participant dies following the separation from service and prior to the payment of any amounts delayed on account of Section 409A, such amounts shall be paid to the personal representative of Participant’s estate within 30 days following the date of Participant’s death.

10.No Guarantee of Tax Consequences. The Company, Board and Committee make no commitment or guarantee to Participant that any federal, state or local tax treatment will apply or be available to any person eligible for benefits under this Restricted Stock Unit Agreement and assumes no liability whatsoever for the tax consequences to Participant.

15.Remedies. Participant acknowledges that Participant’s violation of any of the covenants contained in Section 11 or 13 would cause irreparable damage to the Companies in an amount that would be material but not readily ascertainable, and that any remedy at law (including the payment of damages) would be inadequate. Accordingly, Participant agrees that, notwithstanding any provision of this Restricted Stock Unit Agreement to the contrary, in addition to any other damages it is able to show, in the event of Participant’s violation of any of the covenants contained in Section 11 or 13, the Companies shall be entitled (without the necessity of showing economic loss or other actual damage) to (i) cancel of any portion of this Award that is unvested as of the date of such violation, (ii) the prompt repayment by Participant of the value of any portion of this Award that has previously vested as of the date of such violation and (iii) injunctive relief (including temporary restraining orders, preliminary injunctions and permanent injunctions), without posting a bond, in any court of competent jurisdiction for any actual or threatened breach of any of the covenants set forth in Section 11 or 13, in addition to any other legal or equitable remedies it may have. The preceding sentence shall not be construed as a waiver of the rights that the Companies may have for damages under this Restricted Stock Unit Agreement or otherwise, and all such rights shall be unrestricted. The Noncompetition Period and Nonsolicitation Period shall be tolled during (and shall be deemed automatically extended by) any period during which Participant is in violation of the applicable covenants.

The Restricted Stock Units determined to be earned and eligible to vest under this Restricted Stock Unit Agreement shall be determined in accordance with this Exhibit A.

“Core Income” means net income after taxes and extraordinary items, less net income attributable to noncontrolling interest, gain on the sale of held to maturity and available for sale securities, amortization of intangibles, goodwill and nonrecurring items.

“Core ROATCE” means Core Income as a percent of average tangible common equity.

“Peer Group” means Texas Capital Bancshares, Inc., Cullen/Frost Bankers, Inc., Prosperity Bancshares, Inc., Pinnacle Financial Partners, Inc., Bank OZK, BancorpSouth Bank, Old National Bancorp, United Bankshares, Inc., Ameris Bancorp, Atlantic Union Bankshares Corporation, Cadence Bancorporation, South State Corporation, Hilltop Holdings Inc., Glacier Bancorp, Inc., First Financial Bancorp., Trustmark Corporation, Renasant Corporation, Heartland Financial USA, Inc., United Community Banks, Inc., First Merchants Corporation, First Financial Bankshares, Inc. and Veritex Holdings, Inc.

“Performance Period” means the period from July 1, 2020 through June 30, 2024.

“Relative Core ROATCE” means the simple average of the Company’s Core ROATCE for the Performance Period relative to the simple average of the Core ROATCE of each member of the Peer Group for the Performance Period. The simple average of Core ROATCE for the Performance Period shall be determined by averaging Core ROATCE for each annual period (i.e., July 1 to June 30) of the Performance Period. If Core ROATCE is not available for any member of the Peer Group, the Committee may, in its discretion, exclude that Peer Group member from the determination of Relative Core ROATCE or determine Relative Core ROATCE using the most recent information available for the Peer Group member.

The percentage of the Restricted Stock Units (and related accrued dividends) that are earned and vest upon the Committee’s certification of the performance goals shall be determined as follows:

•If the Company’s Relative Core ROATCE is less than the 25th percentile of the Peer Group, none of the Restricted Stock Units shall be eligible to vest.

•If the Company’s Relative Core ROATCE is at the 25th percentile of the Peer Group, 50% of the target number of Restricted Stock Units (rounded to the nearest whole share) shall be eligible to vest.

•If the Company’s Relative Core ROATCE is at the 50th percentile of the Peer Group, 100% of the target number of Restricted Stock Units shall be eligible to vest.

•If the Company’s Relative Core ROATCE is at or above the 75th percentile of the Peer Group, 150% of the target number of Restricted Stock Units shall be eligible to vest.

If the Company’s Relative Core ROATCE is between the levels indicated above, the number of Restricted Stock Units that vest shall be determined based on straight-line interpolation between the two nearest vesting levels described above.

The Committee shall, in its sole discretion, determine the extent to which the performance goals are satisfied. The Committee shall certify the satisfaction of the performance goals as soon as reasonably practicable following the end of the Performance Period (and in no event later than September 30, 2024).
