process for a Non-Employee Director’s or beneficiary’s debts or other obligations. 
 (i) Domestic Relations Order.
In the event the Committee receives a Domestic Relations Order from a potential Alternate Payee, the Committee shall promptly notify the Non-Employee Director, Former Non-Employee Director or Beneficiary whose benefit is the subject of such order
and provide him/her with information concerning the Plans’ procedures for administering QDROs. Unless and until the order is set aside, the following provisions shall apply:

violate Section 409A of the Code and any regulations promulgated hereunder and no payment shall occur prior to the date that the Non-Employee Director or Former Non-Employee Director whose benefits are subject to the QDRO would have been
entitled to receive payment in accordance with any Deferral 

  

 6 








 
Election in existence as of the date of the QDRO. In the event that the QDRO applies to deferrals which occur after the date of the QDRO, the Alternate Payee
shall be entitled to a distribution on such future deferrals on the date that the Non-Employee Director or Former Non-Employee Director would have been entitled to receive payment 
 (j) QDRO definitions. For purposes of 5(i) the following definitions and rules shall apply: 
 (i) “Alternate Payee” shall mean any spouse, former spouse, child or other dependent of a Non-Employee Director or Former

domestic relations law (including a community property law). 
 (iii) “Qualified Domestic Relations Order” shall
mean any Domestic Relations Order which satisfies the criteria set forth as a QDRO under policies established by the Committee. 
 (k) Change in Ownership or Effective Control. In the event there is a “Change in Ownership or Effective Control” regarding the Company, then notwithstanding any the terms of any Deferral Election, all Deferred Benefits under this
Plan shall become due and payable upon the date established by the Committee as the effective date of the change of control. Notwithstanding the foregoing, with respect to “Specified Employees” as defined under Section 409A of the
Code, Specified Employee’s benefits will be payable 6 months after the date non Specified Employee’s Deferred Benefits are payable under this Section 5(k). For purposes of this paragraph, “Change in Ownership or Effective

the Non-Employee Director’s death by executing a beneficiary designation form provided by the Company. 
 (b) Change of
Beneficiary Designation. A Non-Employee Director may change an earlier beneficiary designation by executing a later beneficiary designation form and delivering it to the Company. The execution of a beneficiary designation form and its receipt by the
Company revokes and rescinds any prior beneficiary designation form.

or of options, warrants or rights to purchase stock or of bonds, debentures, preferred or prior preference stocks having rights superior to or affecting the Common Stock or the rights thereof or which are convertible into or exchangeable for Common
Stock, or 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. 
 (b) Change in Capitalization. Notwithstanding any other provision of the Plan, in the event of any change in the outstanding Common Stock
by reason of a stock dividend, recapitalization, reclassification, reorganization, merger, consolidation, stock split, combination, exchange of shares or other transaction: (i) such proportionate adjustments as may be necessary (as determined
by the Committee in its sole discretion) to reflect such change shall be made to prevent dilution or enlargement of the rights of Non-Employee Directors under the Plan with respect to the aggregate number of shares of Common Stock authorized to be
awarded under the Plan and the number of Stock Units credited to a Non-Employee Director’s Deferred Compensation Account, and (ii) the Committee may make such other adjustments, consistent with the foregoing, as it deems appropriate in its
sole discretion.

action. The cash amount paid for each Stock Unit shall be the Fair Market Value of a share of Common Stock as of the date of the consummation of such proposed action. 
 8. Plan Limit, Termination and Amendment of the Plan. 
 (a) Plan Limit. If the Plan Limit has
been reached, no additional Director Fees may be deferred after that date and any dividend equivalents credited thereafter shall be credited as a bookkeeping “cash” amount, rather than as Stock Units, and shall be credited with interest,

applicable law or stock exchange rule; and, provided further, that the Board may not, without stockholder approval, increase the maximum number of shares issuable under the Plan, except as provided in Section 7(b) above.

such distribution shall be subject to the excise tax applicable under Section 409A of the Code. 
 9. Miscellaneous. 
 (a) No Right to Reelection. Nothing in the Plan shall be deemed to create any obligation on the part of the Board or Bank Board to
nominate any of its members for reelection by the Company’s stockholders, nor confer upon any Non-Employee Director the right to remain a member of the Board or Bank Board or an Advisory Director for any period of time, or at any particular
rate of compensation.

 9 








 (ii) Deferred Benefits. A Deferred Benefit represents at all times an unfunded and
unsecured contractual obligation of the Company and each Non-Employee Director or beneficiary will be a general unsecured creditor of the Bank. No Non-Employee Director, beneficiary or an other person shall have any interest in any fund or in any
specific asset of the Bank by reason of any amount credited to him hereunder, nor shall any Non-Employee Director, beneficiary or any other person have any right to receive any distribution under the Plan except as, and to the extent, expressly
provided in the Plan.

rules, regulations, and other requirements of the Securities and Exchange Commission or any exchange upon which the Common Stock is then listed, and any applicable federal or state securities law, and the Committee may cause a legend or legends to
be put on any such certificates to make appropriate reference to such restrictions. No shares of Common Stock shall be issued hereunder unless the Company shall have determined that such issuance is in compliance with, or pursuant to an exemption
from, all applicable federal and state securities laws. 
 (e) Expenses. The costs and expenses of administering the Plan
shall be borne by the Bank. 
 (f) Applicable Law. Except as to matters of federal law, the Plan and all actions taken
thereunder shall be governed by and construed in accordance with the laws of the State of Texas without giving effect to conflicts of law principles. 
 (g) Effective Date. The Plan shall be effective as of January 1, 2002, with amendments effective as of November 5, 2003. The second amendment and restatement of the Plan shall be effective January 1,
2005, and shall be effective only with respect to amounts deferred and vested on or after January 1, 2005. The fourth amended and restated version of the plan, to the extent necessary to comply with 409A of the Code is deemed effective

the provisions of the second, third and fourth amendments and restatements but shall be subject to the provisions of the Plan in place prior to such amendment and restatement.

 (h) Section 409A. This Plan is intended to meet the requirements of
Section 409A of the Code, and shall be administered in a manner that is intended to meet those requirements and shall be construed and interpreted in accordance with such intent. To the extent that an award or payment, or the settlement or
deferral thereof, is subject to Section 409A of the Code, except as the Committee otherwise determines in writing, the award shall be granted, paid, settled or deferred in a manner that will meet the requirements of Section 409A of the
Code, including regulations or other guidance issued with respect thereto, such that the grant, payment, settlement or deferral shall not be subject to the excise tax applicable under Section 409A of the Code. Any provision of this Agreement
that would cause the award or the payment, settlement or deferral thereof to fail to satisfy Section 409A of the Code shall be amended to comply with Section 409A of the Code on a timely basis, which may be made on a retroactive basis, in
accordance with regulations and other guidance issued under Section 409A of the Code.
