NOW, THEREFORE, in consideration of the promises and the mutual covenants herein contained, the Bank, the Corporation and the Employee hereby agree as follows:

Subject to the Employee being an active employee of OmniAmerican in good standing immediately prior to the Effective Date, the Bank will employ the Employee on the Effective Date as the Executive Vice President and Senior Lending Officer — North Texas Region of the Bank, subject to the terms and subject to the conditions contained in this Agreement. The Employee agrees to provide full-time services for the Bank during the term of this Agreement. The Employee agrees to devote her best efforts to the business of the Bank, and shall perform her duties in a diligent, trustworthy, and business-like manner, all for the purpose of advancing the business of the Bank. Notwithstanding the above, the Employee may

engage in other business interests or investments which do not conflict with the interests of Bank or materially prevent the Employee from performing her contemplated services hereunder on behalf of the Bank.

2. Duties. In her capacity as Executive Vice President and Senior Lending Officer — North Texas Region of the Bank, the Employee shall have such responsibilities and shall render such services as shall be assigned to her from time to time by the Chief Executive Officer of the Bank.

During the term of this Agreement, it is agreed that Bank/Corporation may not reduce Employee’s base salary in any calendar year by an amount in excess of five (5%) percent of the base salary unless such reduction is part of a general reduction in compensation among employees of the same or similar category.

(b) Signing Bonus. The Bank will pay to the Employee a signing bonus in the amount of $50,000 within 30 days of the Effective Date.

(c) Annual Incentive. During the Employment Period, Employee will be entitled to participate in the Bank’s annual incentive program, pursuant to which she will

The Bank shall also reimburse Employee’s reasonable expenses for continuing education courses necessary to maintain any certifications or licenses Employee may hold.

5. Termination of Employment. The Employee’s employment with the Bank may be terminated at any time by either party for the reasons set forth in this Section 5.

(a) Termination by the Employee. Employee may terminate her employment during the Employment Period for Good Reason or for no reason. For the purpose of this Agreement, “Good Reason” shall mean:

(i) Without the Employee’s express written consent, the assignment to the Employee of any duties or responsibilities inconsistent in any material respect with the Employee’s position (including status, offices, titles and reporting relationships), authority, duties or responsibilities as in effect of the Effective Date, or any other action by the Bank which results in a diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Bank promptly after receipt of notice thereof given by the Employee;

(ii) A reduction by the Bank or Corporation in the Employee’s Base Salary;

(iii) The failure by the Bank or Corporation (a) to continue in effect any compensation plan in which the Employee participates as of the Effective Date that is material to the Employee’s total compensation, unless an equitable arrangement (embodied in an ongoing substitute or alternative plan) has been made with respect to such plan, or (b) to continue the Employee’s participation therein (or in such substitute or alternative plan) on a basis not materially less favorable, both in terms of the amount of benefits provided and the level of the Employee’s participation relative to other participants;

(iv) Any failure of the Bank or Corporation to obtain the assumption of, or the agreement to perform, this Agreement by any successor as contemplated in Section 13(a) hereof;

(v) The material breach by the Bank or Corporation of any other provision of this Agreement; or

(vi) A relocation of the Employee’s principal place of employment by more than 30 miles from its location as of the Effective Date without the Employee’s consent.

A termination by Executive shall not constitute termination for Good Reason unless Executive shall first have delivered to the Bank written notice setting forth with specificity the occurrence deemed to give rise to a right to terminate for Good Reason (which notice must be given no later than 90 days after the initial occurrence of such event), and there shall have passed a reasonable time (not less than 30 days) within which the Bank may take action to correct, rescind or otherwise substantially reverse the occurrence supporting termination for Good Reason as identified by Executive. Good Reason shall not include Executive’s death or Disability or Retirement.

(b) Termination by the Bank. The Bank may terminate the Employee’s employment during the Employment Period with or without Cause. For purposes of this Agreement, “Cause” shall mean:

(i) Employee’s material failure to perform Employee’s duties with the Bank (other than any such failure resulting from incapacity due to physical or mental illness), after a written demand for performance is delivered to Employee by the Bank which specifically identifies the manner in which the Bank believes that Employee has intentionally and materially failed to perform Employee’s duties; or

(ii) Employee’s engaging in any illegal conduct or misconduct that is materially and demonstrably injurious to the Bank, its financial condition, or its reputation; or

(iii) Employee’s engaging in any act or omission that constitutes, on the part of the Employee, fraud, theft, misappropriation, embezzlement, breach of fiduciary duty or dishonesty; or

(iv) Entry of an order by any state or federal regulatory agency either removing Employee from Employee’s position with the Bank or its affiliates or prohibiting Employee from participating in the conduct of the affairs of the Bank or any of its affiliates; or

(v) Employee’s failure to cure a material breach of any provision of this Agreement after a written demand for cure is delivered to Employee by the Bank.

Termination for Cause shall only occur after the Board, in its sole and absolute discretion, has made a full and thorough determination of “Cause.”

Additionally, Employee’s employment may be terminated by Bank as a result of a Change in Control, as defined in Section 7 hereof. Such a termination of employment shall be treated the same as a termination without Cause for purposes of Section 6 of this

Agreement.

(c) Death, Retirement or Disability. The Employee’s employment shall terminate automatically upon the death or Retirement of the Employee during the Employment Period. For purposes of this Agreement, “Retirement” shall mean normal retirement as defined in the Bank’s or Corporation’s then-current retirement plan, or if there is no such retirement plan, “Retirement” shall mean voluntary termination after attaining age 65. If the Bank determines in good faith that the Disability of the Employee has occurred during the Employment Period (pursuant to the definition of Disability set forth below), it may give to the Employee written notice of its intention to terminate the Employee’s employment. In such event, the Employee’s employment with the Bank shall terminate effective on the 30th day after receipt of such written notice by the Employee (the “Disability Effective Date”), provided that, within the 30 days after such receipt, the Employee shall not have returned to full-time performance of the Employee’s duties. For purposes of this Agreement, “Disability” shall mean the inability of the Employee, as determined by the Board, to perform the essential functions of her regular duties and responsibilities, with or without reasonable accommodation, due to a medically determinable physical or mental illness which has lasted (or can reasonably be expected to last) for a period of six (6) consecutive months.

(d) Notice of Termination. Any termination by the Bank for Cause, or by the Employee for Good Reason, shall be communicated by Notice of Termination to the other party hereto given in accordance with Section 13(c) of this Agreement. For purposes of this Agreement, a “Notice of Termination” means a written notice which (i) indicates the specific termination provision in this Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Employee’s employment under the provision so indicated and (iii) specifies the termination date. The failure by the Employee or the Bank to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause shall not waive any right of the Employee or the Bank, respectively, hereunder or preclude the Employee or the Bank, respectively, from asserting such fact or circumstance in enforcing the Employee’s or the Bank’s rights hereunder.

(e) Date of Termination. “Date of Termination” means (i) if the Employee’s employment is terminated by the Bank for Cause, or by the Employee for Good Reason, the date of termination as specified in the Notice of Termination, (ii) if the Employee’s employment is terminated by the Bank other than for Cause, the Date of Termination shall be either the date on which the Bank notifies the Employee of such termination or a date otherwise specified by the Bank, (iii) if the Employee’s employment is terminated by reason of death, Retirement or Disability, the Date of Termination shall be the date of the death or Retirement of the Employee or the Disability Effective Date, as the case may be, and (iv) if the Employee’s employment is terminated by the Employee without Good Reason, the Date of Termination shall be at least two (2) weeks from the date that the Employee notifies the Bank of her resignation (during which two (2) week period

Employee may be required, in the discretion of Bank, to continue to perform services on behalf of Bank)..

(ii) all grants of stock options and other equity awards granted by the Bank or Corporation and held by the Employee as of the Date of Termination will become immediately vested and exercisable as of the Date of Termination and, to the extent necessary, this Agreement is hereby deemed an amendment of any such outstanding stock option or other equity award; and

(iii) to the extent not theretofore paid or provided, the Bank shall timely pay or provide to the Employee any other amounts or benefits required to be paid or provided or which the Employee is eligible to receive under any plan, program, policy or practice of the Bank to the extent provided to Peer Officers prior to the Date of Termination (such other amounts and benefits shall be hereinafter referred to as the “Other Benefits”).

(c) Death. If the Employee’s employment is terminated by reason of Employee’s death during the Employment Period, then this Agreement will terminate without further obligations to Employee, other than for payment to Employee’s estate or

(i) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any payment or distribution by the Bank to or for the benefit of the Employee (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (a “Payment” would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then, prior to the making of any Payment to the Employee, a calculation shall be made comparing (i) the net benefit

to the Employee of the Payment after payment of the Excise Tax, to (ii) the net benefit to the Employee if the Payment had been limited to the extent necessary to avoid being subject to the Excise Tax. If the amount calculated under (i) above is less than the amount calculated under (ii) above, then the Payment shall be limited to the extent necessary to avoid being subject to the Excise Tax (the “Reduced Amount”). In that event, the Employee shall direct which Payments are to be modified or reduced.

7. Change in Control. For purposes of this Agreement, “Change in Control” shall mean the occurrence of any one of the following: a Change in the Actual Control, as described in Section 7(i), a Change in Effective Control, as described in Section 7(ii), or a Change in the Ownership of Assets, as described in Section 7(iii).

(i) Change in Actual Control shall mean the acquisition by any one person, or more than one person acting as a group (as defined in subsection (iv), below) of ownership of stock of the Corporation or Bank that, together with stock held by such person or group, constitutes more than 50 percent of the total fair market value or total voting power of the stock of the Corporation or Bank. However, if any one person, or more than one person acting as a group, is considered to own more than 50 percent of the total fair market value or total voting power of the stock of the Corporation or Bank, the acquisition of additional stock by the same person or persons is not considered to cause a change in the ownership of the Corporation or Bank (or to cause a change in the effective control of the Corporation or Bank (within the meaning of Section 7(a)(ii). An increase in the percentage of stock owned by any one person, or persons acting as a group, as a result of a transaction in which the Corporation or Bank acquires its stock in exchange for property will be treated as an acquisition of stock for purposes of this section.

(ii) Change in Effective Control shall mean: (A) The acquisition by any one person, or more than one person acting as a group (as defined in Section (iv), below), during any 12-month period of stock of the Corporation or Bank possessing 35 percent or more of the total voting power of the stock of the Corporation or Bank; or (B) The replacement, of a majority of members of the Corporation’s or Bank’s board of directors during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Corporation’s or Bank’s board of directors prior to the date of election in accordance with Treasury Regulation § 1.409A-1(g)(5)(iv)(A)(2). Notwithstanding the foregoing, if any one person, or more than one person acting as a group, is considered to effectively control the Corporation or Bank (within the meaning of this subsection (ii)), the acquisition of additional control of the Corporation or Bank by the same person or persons is not considered to cause a Change in Control.

(iii) Change in the Ownership of the Corporation’s or Bank’s Assets shall mean the acquisition by any one person, or more than one person acting as a group (as defined in subsection (iv), below), during any 12-month period of assets from the Corporation or Bank that have a total gross fair market value equal to or more than 40 percent of the total gross fair market value of all of the assets of the Corporation or Bank immediately prior to such acquisition or acquisitions. Notwithstanding the foregoing, there is no change in control event under this section when there is a transfer to an entity that is controlled by the shareholders of the Corporation or Bank immediately after the transfer.

(iv) Persons acting as a group. For purposes of this Section 7, persons will not be considered to be acting as a group solely because they purchase or own stock of the same corporation at the same time, or as a result of the same public offering. However, persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the corporation. If a person, including an entity, owns stock in both corporations that enter into a merger, consolidation, purchase or acquisition of stock, or similar transaction, such shareholder is considered to be acting as a group with other shareholders in a corporation prior to the transaction giving rise to the change and not with respect to the ownership interest in the other corporation.

8. Delivery of Documents upon Termination. The Employee shall deliver to the Bank or its designee at the termination of the Employee’s employment, or at any time as requested by the Bank, all correspondence, memoranda, notes, records, drawings, sketches, plans, customer lists, product compositions, and other documents and all copies thereof, made, composed or received by the Employee, solely or jointly with others, that are in the Employee’s possession, custody, or control at termination and that are related in any manner to the past, present, or anticipated business or any member of the Bank. The Employee will not make, distribute, or retain copies of any such information or property. To the extent that Employee has electronic files or information in her/her possession or control that belong to the Bank or contain

Confidential Information (specifically including but not limited to electronic files or information stored on personal computers, mobile devices, electronic media, or in cloud storage), on or prior to the termination, or at any other time the Bank requests, Employee shall (a) provide the Bank with an electronic copy of all of such files or information (in an electronic format that readily accessible by the Bank); (b) after doing so, delete all such files and information, including all copies and derivatives thereof, from all non-Bank-owned computers, mobile devices, electronic media, cloud storage, or other media, devices, or equipment, such that such files and information are permanently deleted and irretrievable; and (c) if requested by Bank, provide a written certification to the Bank that the required deletions have been completed and specifying the files and information deleted and the media source from which they were deleted.

9. Restrictions on Conduct.

(a) General. Employee and the Bank understand and agree that the purpose of the provisions of this Section 9 is to protect the legitimate business interests of the Bank, as more fully described below, and is not intended to eliminate Employee’s post-employment competition with the Bank per se, nor is it intended to impair or infringe upon Employee’s right to work, earn a living, or acquire and possess property from the fruits of her labor. Employee hereby acknowledges that Employee has received good and valuable consideration for the post-employment restrictions set forth in this Section 9 in the form of her employment and the compensation and benefits provided for herein. Employee hereby further acknowledges that the post-employment restrictions set forth in this Section 9 are reasonable and that they do not, and will not, unduly impair her ability to earn a living after the termination of this Agreement.

Therefore, subject to the limitations of reasonableness imposed by law, Employee shall be subject to the restrictions set forth in this Section 9.

In consideration of the compensation and benefits being paid and to be paid by the Bank to Employee hereunder, Employee hereby agrees that, during the Restricted Period, Employee will not, without prior written consent of the Bank, directly or indirectly, engage in or otherwise provide Competitive Services within the Restricted Territory on her own behalf or as a Principal or Representative of any other Person; provided, however, that the provisions of this Agreement shall not be deemed to prohibit the ownership by Employee of not more than five percent (5%) of any class of securities of any corporation having a class of securities registered pursuant to the Securities Exchange Act of 1934, as amended.

(ii) Restriction on Disclosure and Use of Confidential Information and Trade Secrets. Employee understands and agrees that the Confidential Information and Trade Secrets constitute valuable assets of the Bank and may not be converted to Employee’s own use. Accordingly, Employee hereby agrees that Employee shall not, directly or indirectly, at any time during the Restricted Period, reveal, divulge, or disclose to any Person not expressly authorized by the Bank any Confidential Information, and Employee shall not, directly or indirectly, at any time during the Restricted Period, use or make use of any Confidential Information in connection with any business activity other than that of the Bank. Throughout the term of this Agreement and at all times after the date that this Agreement terminates for any reason, Employee shall not directly or indirectly transmit or disclose any Trade Secret of the Bank to any Person, and shall not make use of any such Trade Secret, directly or indirectly, for herself or for others, without the prior written consent of the Bank. The parties acknowledge and agree that this Agreement is not intended to, and does not, alter either the Bank’s rights or Employee’s obligations under any applicable state or federal statutory or common law regarding trade secrets and unfair trade practices.

Anything herein to the contrary notwithstanding, Employee shall not be restricted from disclosing or using Confidential Information that is required to be disclosed by law, court order or other legal process; provided, however, that in the event disclosure is required by law, Employee shall provide the Bank with prompt

notice of such requirement so that the Bank may seek an appropriate protective order prior to any such required disclosure by Employee.

(iii) Nonsolicitation of Protected Employees. Employee understands and agrees that the relationship between the Bank and each of its Protected Employees constitutes a valuable asset of the Bank and may not be converted to Employee’s own use. Accordingly, Employee hereby agrees that during the Restricted Period, Employee shall not directly or indirectly, on Employee’s own behalf or as a Principal or Representative of any Person, solicit or induce any Protected Employee to terminate her or her employment relationship with the Bank or to enter into employment with any other Person.

(iv) Restriction on Relationships with Protected Customers. Employee understands and agrees that the relationship between the Bank and each of its Protected Customers constitutes a valuable asset of the Bank and may not be converted to Employee’s own use. Accordingly, Employee hereby agrees that, during the Restricted Period, Employee shall not, without the prior written consent of the Bank, directly or indirectly, on Employee’s own behalf or as a Principal or Representative of any Person, solicit, divert, take away or attempt to solicit, divert or take away a Protected Customer; provided, however, that the prohibition of this covenant shall apply only to Protected Customers with whom Employee had Material Contact on the Bank’s behalf during the Employment Period. For purposes of this Agreement, Employee had “Material Contact” with a Protected Customer if (a) she had business dealings with the Protected Customer on the Bank’s behalf; (b) she was responsible for supervising or coordinating the dealings between the Bank and the Protected Customer; or (c) she obtained Trade Secrets and/or Confidential Information about the customer as a result of her association with the Bank.

(d) Enforcement of Restrictive Covenants.

(i) Rights and Remedies Upon Breach. In the event Employee breaches, or threatens to commit a breach of, any of the provisions of the Restrictive Covenants, the Bank shall have the following rights and remedies, which shall be independent of any others and severally enforceable, and shall be in addition to, and not in lieu of, any other rights and remedies available to the Bank at law or in equity:

(A) the right and remedy to enjoin, preliminarily and permanently and without the necessity of posting bond, Employee from violating or threatening to violate the Restrictive Covenants and to have the Restrictive Covenants specifically enforced by any court of competent jurisdiction, it being agreed that any breach or threatened breach of the Restrictive Covenants would cause irreparable injury to the Bank and that money damages would not provide an adequate remedy to the Bank;

(B) the right and remedy to require Employee to account for and pay over to the Bank all compensation, profits, monies, accruals, increments or other benefits derived or received by Employee as the result of any transactions constituting a breach of the Restrictive Covenants; and

(C) the right and remedy to require Employee to pay the reasonable attorneys’ fees incurred by Bank in enforcing the Restrictive Covenants.

(ii) Severability of Covenants. Employee acknowledges and agrees that the Restrictive Covenants are reasonable and valid in time and scope and in all other respects. The covenants set forth in this Agreement shall be considered and construed as separate and independent covenants. Should any part or provision of any covenant be held invalid, void or unenforceable in any court of competent jurisdiction, such invalidity, voidness or unenforceability shall not render invalid, void or unenforceable any other part or provision of this Agreement.

(iii) Reformation. The parties hereunder agree that it is their intention that the Restrictive Covenants be enforced in accordance with their terms to the maximum extent possible under applicable law. If any portion of the foregoing provisions is found to be invalid or unenforceable by a court of competent jurisdiction, the invalid or unreasonable term shall be redefined, or a new enforceable term provided, such that the intent of the Bank and Employee in agreeing to the provisions of this Agreement will not be impaired and the provision in question shall be enforceable to the fullest extent of applicable law.

10. Publicity and Advertising. The Employee agrees that the Bank may use the Employee’s name, picture, or likeness for any advertising, publicity, or other business purpose at any time, during the term of the Agreement by the Bank and may continue to use materials generated during the term of the Agreement for a period of 6 months thereafter. The Employee shall receive no additional consideration if the Employee’s name, picture or likeness is so used. The Employee further agrees that any negatives, prints or other material for printing or reproduction purposes prepared in connection with the use of the Employee’s name, picture or likeness by the Bank shall be and are the sole property of the Bank.

11. Dispute Resolution. Subject to the Bank’s right to seek injunctive relief in court as provided in Section 9 of this Agreement, any dispute, controversy or claim arising out of or in relation to or connection to this Agreement, including without limitation any dispute as to the construction, validity, interpretation, enforceability or breach of this Agreement, including a claim for indemnification under Section 12, shall be resolved either as provided by applicable law, or, at the option of either party, by impartial binding arbitration. In the event that either the Bank or the Employee demands arbitration, the Employee and the Bank agree that such arbitration shall be the exclusive, final and binding forum for the ultimate resolution of such

claims, subject to any rights of appeal that either party may have under the Federal Arbitration Act and/or under applicable state law dealing with the review of arbitration decisions.

(a) Arbitration. Arbitration shall be heard and determined by one arbitrator, who shall be impartial and who shall be selected by mutual agreement of the parties; provided, however, that if the dispute involves more than $1,000,000, then the arbitration shall be heard and determined by three (3) arbitrators. If three (3) arbitrators are necessary as provided above, then (i) each side shall appoint an arbitrator of its choice within thirty (30) days of the submission of a notice of arbitration and (ii) the party-appointed arbitrators shall in turn appoint a presiding arbitrator of the tribunal within thirty (30) days following the appointment of the last party-appointed arbitrator. If any party fails or refuses to appoint an arbitrator, the arbitration shall proceed with one (1) arbitrator.

(b) Demand for Arbitration. In the event that the Employee or the Bank initially elects to file suit in any court, the other party will have 60 days from the date that it is formally served with a summons and a copy of the suit to notify the party filing the suit of the non-filing party’s demand for arbitration. In that case, the suit must be dismissed by consent of the parties or by the court on motion, and arbitration commenced with the arbitrators. In situations where suit has not been filed, either the Employee or the Bank may initiate arbitration by serving a written demand for arbitration upon the other party. Such a demand must be served within twelve months of the events giving rise to the dispute. Any claim that is not timely made will be deemed waived.

(i) The arbitration proceedings shall be held in Tyler, TX;

(ii) The arbitrators shall be and remain at all times wholly independent and impartial;

(iii) The arbitration proceedings shall be conducted in accordance with the Employment Arbitration Rules of the American Arbitration Association, as amended from time to time;

(iv) Any procedural issues not determined under the arbitral rules selected pursuant to item (iii) above shall be determined by the law of the place of arbitration, other than those laws which would refer the matter to another jurisdiction;

(v) The costs of the arbitration proceedings (including attorneys’ fees and costs) shall be borne in the manner determined by the arbitrators;

(vi) The arbitrators may grant any remedy or relief that would have been available to the parties had the matter been heard in court;

(vii) The decision of the arbitrators shall be reduced to writing; final and binding without the right of appeal; the sole and exclusive remedy regarding any claims, counterclaims, issues or accounting presented to the arbitrators; made and promptly paid in United States dollars free of any deduction or offset; and any costs or fees incident to enforcing the award shall to the maximum extent permitted by law, be charged against the party resisting such enforcement;

(viii) The award shall include interest from the date of any breach or violation of this Agreement, as determined by the arbitral award, and from the date of the award until paid in full, at 6% per annum; and

(ix) Judgment upon the award may be entered in any court having jurisdiction over the person or the assets of the party owing the judgment or application may be made to such court for a judicial acceptance of the award and an order of enforcement, as the case may be.

(d) Acknowledgement of Parties. The Bank and Employee understand and acknowledge that this Agreement means that neither can pursue an action against the other in a court of law regarding any employment dispute, except for claims involving workers’ compensation benefits or unemployment benefits, and except as set forth elsewhere in this Agreement, in the event that either party notifies the other of its demand for arbitration under this Agreement. The Bank and Employee understand and agree that this Section 11, concerning arbitration, shall not include any controversies or claims related to any agreements or provisions (including provisions in this Agreement) respecting confidentiality, proprietary information, non-competition, non-solicitation, trade secrets, or breaches of fiduciary obligations by the Employee, which shall not be subject to arbitration.

(e) Consultation. Employee has been advised of the Employee’s right to consult with an attorney prior to entering into this Agreement.

12. Indemnification. Bank shall indemnify and hold Employee harmless against any legal judgments or awards rendered against Bank or Employee in her capacity as an officer, director or employee of Bank. Bank likewise shall pay for all reasonable legal fees and expenses incurred by Employee in connection with any legal action brought against the Bank or Employee in her capacity as an officer, director or employee of Bank. Provided, however, that indemnification shall not be provided for willful or intentional acts committed by Employee in violation of the law.

13. Code Section 409A.

(a) General. This Agreement shall be interpreted and administered in a manner so that any amount or benefit payable hereunder shall be paid or provided in a manner that is either exempt from or compliant with the requirements of Section 409A of the Code and applicable Internal Revenue Service guidance and Treasury Regulations issued thereunder (and

any applicable transition relief under Section 409A of the Code). Nevertheless, the tax treatment of the benefits provided under the Agreement is not warranted or guaranteed. Neither the Bank nor its directors, officers, employees or advisers shall be held liable for any taxes, interest, penalties or other monetary amounts owed by Executive as a result of the application of Section 409A of the Code.

(b) Definitional Restrictions. Notwithstanding anything in this Agreement to the contrary, to the extent that any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code (“Non-Exempt Deferred Compensation”) would otherwise be payable or distributable hereunder, or a different form of payment of such Non-Exempt Deferred Compensation would be effected, by reason of a Change in Control or Executive’s Disability or termination of employment, such Non-Exempt Deferred Compensation will not be payable or distributable to Executive, and/or such different form of payment will not be effected, by reason of such circumstance unless the circumstances giving rise to such Change in Control, Disability or termination of employment, as the case may be, meet any description or definition of “change in control event”, “disability” or “separation from service”, as the case may be, in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition). This provision does not affect the dollar amount or prohibit the vesting of any Non-Exempt Deferred Compensation upon a Change in Control, Disability or termination of employment, however defined. If this provision prevents the payment or distribution of any Non-Exempt Deferred Compensation, or the application of a different form of payment, such payment or distribution shall be made at the time and in the form that would have applied absent the non-409A-conforming event.

(c) Six-Month Delay in Certain Circumstances. Notwithstanding anything in this Agreement to the contrary, if any amount or benefit that would constitute Non-Exempt Deferred Compensation would otherwise be payable or distributable under this Agreement by reason of Executive’s separation from service during a period in which she is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment by the Bank under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes):

(i) the amount of such Non-Exempt Deferred Compensation that would otherwise be payable during the six-month period immediately following Executive’s separation from service will be accumulated through and paid or provided on the first day of the seventh month following Executive’s separation from service (or, if Executive dies during such period, within 30 days after Executive’s death) (in either case, the “Required Delay Period”); and

(ii) the normal payment or distribution schedule for any remaining payments or distributions will resume at the end of the Required Delay Period.

For purposes of this Agreement, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder.

(d) Timing of Release of Claims. Whenever in this Agreement a payment or benefit is conditioned on Executive’s execution of a release of claims, such release must be executed and all revocation periods shall have expired within 60 days after the Date of Termination; failing which such payment or benefit shall be forfeited. If such payment or benefit constitutes Non-Exempt Deferred Compensation, and if such 60-day period begins in one calendar year and ends in the next calendar year, the payment or benefit shall not be made or commence before the second such calendar year, even if the release becomes irrevocable in the first such calendar year. In other words, Executive is not permitted to influence the calendar year of payment based on the timing of her signing of the release.

(f) Timing of Reimbursements and In-kind Benefits. If Executive is entitled to be paid or reimbursed for any taxable expenses under this Agreement, and such payments or reimbursements are includible in Executive’s federal gross taxable income, the amount of such expenses reimbursable in any one calendar year shall not affect the amount reimbursable in any other calendar year, and the reimbursement of an eligible expense must be made no later than December 31 of the year after the year in which the expense was incurred. Executive’s rights to payment or reimbursement of expenses under this Agreement shall not be subject to liquidation or exchange for another benefit.

14. Miscellaneous Provisions.

(a) Successors of the Bank. The Bank will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Bank, by agreement in form and substance satisfactory to the Employee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Bank would be required to perform it if no such succession had taken place. Failure of the Bank to obtain such agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle the Employee to compensation from the Bank in the same amount and on the same terms as the Employee would be entitled hereunder if the Employee terminated her employment for Good Reason, except that for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the Date of Termination. As used in this Agreement, “Bank” as hereinbefore defined shall include any successor to its business and/or assets as aforesaid which executes and delivers the agreement provided for in this Section 13 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law.

(b) Employee’s Heirs, etc. The Employee may not assign the Employee’s rights or delegate the Employee’s duties or obligations hereunder without the written consent of the Bank. This Agreement shall inure to the benefit of and be enforceable by the Employee’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Employee should die while any amounts would still be payable to the Employee hereunder as if she had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the Employee’s designee or, if there be no such designee, to the Employee’s estate.

(c) Notices. Any notice or communication required or permitted under the terms of this Agreement shall be in writing and shall be delivered personally, or sent by registered or certified mail, return receipt requested, postage prepaid, or sent by nationally recognized overnight carrier, postage prepaid, or sent by facsimile transmission to the Bank at the Bank’s principal office and facsimile number in Tyler, TX or to the Employee at the address and facsimile number, if any, appearing on the books and records of the Bank. Such notice or communication shall be deemed given (a) when delivered if personally delivered; (b) five mailing days after having been placed in the mail, if delivered by registered or certified mail; (c) the business day after having been placed with a nationally recognized overnight carrier, if delivered by nationally recognized overnight carrier, and (d) the business day after transmittal when transmitted with electronic confirmation of receipt, if transmitted by facsimile. Any party may change the address or facsimile number to which notices or communications are to be sent to it by giving notice of such change in the manner herein provided for giving notice. Until changed by notice, the following shall be the address and facsimile number to which notices shall be sent:

If to the Bank, to:	Southside Bank
	0000 Xxxxx Xxxxxxx
	Xxxxx, Xxxxx 00000

	FAX:	000-000-0000
	TELE:	903-531-7111

If to the Employee, to:		Xxxx Xxxxxxx
		0000 Xxxxxxx Xxxxx
		Xxxx Xxxxx, XX 00000

(d) Amendment or Waiver. No provisions of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by the Employee and such officer as may be specifically designated by the Board (which shall not include the Employee). No waiver by either party hereto at any time of any breach by the other party hereto of or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party that are not set forth expressly in this Agreement.

(e) Invalid Provisions. Should any portion of this Agreement be adjudged or held to be invalid, unenforceable or void, such holding shall not have the effect of invalidating or voiding the remainder of this Agreement and the parties hereby agree that the portion so held invalid, unenforceable or void shall if possible, be deemed amended or reduced in scope, or otherwise be stricken from this Agreement to the extent required for the purposes of validity and enforcement thereof.

(f) Unreasonable Compensation. If any portion of the Compensation and Benefits provided by this Agreement should be deemed to be unreasonable or disproportionate to the services the Employee provides (under 12 C.F.R. 364 or other applicable law), the Bank shall reduce such Compensation and Benefits to the maximum amount that would be reasonable or proportionate.

(g) Survival of the Employee’s Obligations. The Employee’s obligations under this Agreement shall survive regardless of whether the Employee’s employment by the Bank is terminated, voluntarily or involuntarily, by the Bank or the Employee, with or without Cause. Employee acknowledges that new, independent and valuable benefits have been received by Employee by virtue of this Agreement and such constitutes consideration for Employee’s agreements herein.

(h) Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

(i) Governing Law. This Agreement and any action or proceeding related to it shall be governed by and construed under the laws of the State of Texas without giving effect to its conflicts of law principles.

(j) Captions and Gender. The use of Captions and Section headings herein is for purposes of convenience only and shall not effect the interpretation or substance of any provisions contained herein. Similarly, the use of the masculine gender with respect to pronouns in this Agreement is for purposes of convenience and includes either sex who may be a signatory.

(k) Effect on Prior Agreements. This Agreement, and any attachments, represent the entire understanding between the parties hereto and supersedes in all respects the Change in Control Agreement (including, without limitation, any rights to severance or any change in control payments under the Change in Control Agreement) and any other prior agreements or understandings between the OmniAmerican or the Bank and the Employee regarding the Employee’s employment. By signing this Agreement, the Employee affirmatively acknowledges and agrees that she shall have no right to terminate her employment for “Good Reason,” as defined in this Agreement or the Change in Control Agreement as a result of the Merger.

(l) Independent Consideration. Employee acknowledges that this Agreement is fully supported by new and independent consideration to Employee and fully meets the requirements of Texas laws as they relate to Employment Agreements that contain non-compensation agreements. Employee agrees to all of the terms of this Agreement as part of receiving the new and independent consideration extended to Employee under this Agreement.

IN WITNESS WHEREOF, the Employee and a duly authorized Bank officer have signed this Agreement.
