(i)

Executive shall be eligible to receive any accrued but unpaid Base Salary, any accrued but unused paid time off, in each case, as of the Termination Date (as defined in Section 5.5 of this Agreement), which shall be paid on the first regularly scheduled payroll date following Termination Date (or such earlier date as may be required by applicable law);

Executive’s engagement in dishonesty, illegal conduct or misconduct, which is, in each case as determined by the Bank in its sole discretion, materially injurious to the Bank or any of its affiliates;

(iv)

Executive’s embezzlement, misappropriation or fraud, whether or not related to Executive’s employment with the Bank;

Except for a failure, breach or refusal which, by its nature, cannot reasonably be expected to be cured, Executive shall have thirty (30) calendar days from the delivery of written notice by the Bank within which to cure any acts constituting Cause; provided, however, that if the Bank reasonably expects irreparable injury from a delay of thirty (30) calendar days, the Bank may give Executive notice of such shorter period within which to cure as is reasonable under the circumstances, which may include the termination of Executive’s employment without notice and with immediate effect. If the Bank does not terminate Executive’s employment for Cause within sixty (60) calendar days after the CEO becomes aware of all material facts and circumstances giving rise to the Bank’s right to terminate Executive for Cause, then the Bank will be deemed to have waived the Bank’s right to terminate for Cause with respect to such grounds.

If Executive does not terminate Executive’s employment for Good Reason within sixty (60) calendar days after the first occurrence of the applicable grounds, then Executive will be deemed to have waived Executive’s right to terminate for Good Reason with respect to such grounds.

5.2

The Employment Term and Executive’s employment hereunder may be terminated by Executive for Good Reason or by the Bank without Cause. In the event of such termination, Executive shall be entitled to receive the Accrued Amounts and, subject to Executive’s compliance with Section 6, Section 7 and Section 8 of this Agreement, Executive’s timely execution of a release of claims in favor of the Bank, its affiliates and their respective officers and directors, in a form to be provided by the Bank (the “Release”), and such Release becoming effective within either twenty-eight (28) or fifty-two (52) days, as applicable, following the Termination Date (such 28-day or 52-day period, the “Release Execution Period”), Executive shall be entitled to receive the following compensation and benefits:

(b)

If Executive timely and properly elects continuation coverage under the Consolidated Omnibus Reconciliation Act of 1985 (“COBRA”), the Bank shall reimburse Executive for the monthly COBRA premium paid by Executive for Executive and Executive’s dependents (with the Executive required to pay for any employee-paid portion of such coverage) (such reimbursements to be referred to herein as the “COBRA Benefits”).

RESIGNATION OF ALL OTHER POSITIONS

Upon termination of Executive’s employment hereunder for any reason. Executive shall be deemed to have resigned from all positions that Executive holds with the Bank and its affiliates and as an officer or member of the board of directors (or a committee thereof) or similar governing body of the Bank or any of its affiliates. Executive covenants and agrees to take any and all actions reasonably requested by the Bank to effect or evidence such resignation(s).

5.8

SECTION 280G

(a)

Executive shall bear all expense of, and be solely responsible for, any excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (such excise tax being the “Excise Tax” and such code being the “Code”); provided, however, that any payment or benefit received or to be received by Executive (whether payable under the terms of this Agreement or any other plan, arrangement or agreement with TCBX, any of its affiliates or otherwise (collectively, the “Payments”)) that would constitute a “parachute payment” within the meaning of Section 280G of the Code, shall be reduced to the extent necessary so that no portion thereof shall be subject to the Excise Tax but only if, by reason of such reduction, the net after-tax benefit received by Executive shall exceed the net after-tax benefit that would be received by Executive if no such reduction was made.

(b)

The “net after-tax benefit” shall mean (i) the present value of the Payments which Executive receives or is then entitled to receive that would constitute “parachute payments” within the

meaning of Section 280G of the Code, less (ii) the amount of all federal, state and local income and employment taxes payable by Executive with respect to the foregoing calculated at the highest marginal income tax rate for each year in which the foregoing shall be paid to Executive (based on the rate in effect for such year as set forth in the Code as in effect at the time of the first payment of the foregoing), less (iii) the amount of Excise Tax imposed with respect to the Payments described in clause (b)(i) above.

(c)

All determinations under this Section 5.8 will be made by an actuarial firm, accounting firm, consulting firm or law firm (the “280G Firm”) selected by the Bank. The 280G Firm shall be required to evaluate the extent to which all or a portion of any Payments are exempt from Section 280G as reasonable compensation for personal services rendered before or after the applicable Section 280G change in control event (including, for avoidance of doubt, Payments in respect of a covenant not to compete). The 280G Firm will submit any determination it makes under this Section 5.8 and detailed supporting calculations to each of Executive and the Bank as soon as reasonably practicable.

(d)

If the 280G Firm determines that one or more reductions are required under this Section 5.8, such Payments shall be reduced in a manner that maximizes Executive’s economic position as determined by the 280G Firm. In applying this principle, the reduction shall be made in a manner consistent with the requirements of Section 409A of the Code, and where two economically equivalent amounts are subject to reduction but payable at different times, such amounts shall be reduced on a pro rata basis but not below zero.

(e)

As a result of the uncertainty in the application of Section 280G at the time that the 280G Firm makes its determinations under this Section 5.8, it is possible that amounts will have been paid or distributed to the Executive that should not have been paid or distributed (collectively, the “Overpayments”), or that additional amounts should be paid or distributed to the Executive (collectively, the “Underpayments”). If the 280G Firm determines that an Overpayment has been made, Executive must repay the Overpayment to the Bank, together with interest at the applicable federal rate (as defined in Section 7872(f)(2)(A) of the Code) from the date of Executive’s receipt of the Overpayment until the date of repayment; provided, however, that no loan will be deemed to have been made and no amount will be payable by Executive to the Bank unless, and then only to the extent that, the deemed loan and payment would either reduce the amount on which Executive is subject to tax under Section 4999 of the Code or generate a refund of tax imposed under Section 4999 of the Code. If the 280G Firm determines, based upon controlling precedent or substantial authority, that an Underpayment has occurred, the 280G Firm will notify Executive and the Bank of that determination, and the Bank will promptly pay the amount of that Underpayment to Executive, together with interest at the applicable federal rate (as defined in Section 7872(f)(2)(A) of the Code) from the date the amount would have otherwise been paid to Executive until the payment date.

(f)

The parties will provide the 280G Firm access to and copies of any books, records, and documents in their possession as reasonably requested by the 280G Firm, and otherwise cooperate with the 280G Firm, in connection with the preparation and issuance of the determinations and calculations contemplated by this Section 5.8. For purposes of making the calculations required by this Section 5.8, the 280G Firm may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code.

COOPERATION

The parties agree that certain matters in which Executive will be involved during the Employment Term may necessitate Executive’s cooperation in the future. Accordingly, following the termination of Executive’s employment for any reason, to the extent reasonably requested by the Bank and subject to Executive’s professional commitments, Executive shall cooperate with the Bank in connection with matters arising out of Executive’s service to the Bank; provided that, the Bank shall make reasonable efforts to

minimize disruption of Executive’s other activities. the Bank shall pay Executive a reasonable per diem and reimburse Executive for reasonable expenses incurred in connection with such cooperation.

(c)

Nothing in this Agreement prohibits Executive from reporting possible violations of federal law or regulation to any governmental agency or entity, or making other disclosures that, in each case, are protected under the whistleblower provisions of federal law or regulation. Executive does not need the prior authorization of the Bank to make such reports or disclosures and Executive is not required to notify the Bank that Executive has made such reports or disclosures. In addition, pursuant to 18 USC Section 1833(b), Executive shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made: (1) in confidence to a federal, state or local governmental official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or (2) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. If Executive files a lawsuit for retaliation by the Bank for reporting a suspected violation of law.

7.11

DISCOVERIES AND INVENTIONS; WORK MADE FOR HIRE

(a)

Executive agrees that upon conception and/or development of any idea, discovery, invention, improvement, software, writing or other material or design that: (i) relates to the business of the Bank, or (ii) relates to the Bank’s actual or demonstrably anticipated research or development, or (iii) results from any work performed by the Executive for the Bank, Executive will assign to the Bank the entire right, title and interest in and to any such idea, discovery, invention, improvement, software, writing or other material or design. Executive has no obligation to assign any idea, discovery, invention, improvement, software, writing or other material or design that the Executive conceives and/or develops entirely on Executive’s own time without using the Bank’s equipment, supplies, facilities, or trade secret information unless the idea, discovery, invention, improvement, software, writing or other material or design: (A) relates to the business of the Bank, or (B) relates to the Bank’s actual or demonstrably anticipated research or development, or (C) results from any work performed by Executive for the Bank. Executive agrees that any idea, discovery, invention, improvement, software, writing or other material or design that relates to the business of the Bank or relates to the Bank’s actual or demonstrably anticipated research or development which is conceived or suggested by Executive, either solely or jointly with others, within one (1) year following termination of the Executive’s employment with the Bank shall be presumed to have been so made, conceived or suggested in the course of such employment with the use of the Bank’s equipment, supplies, facilities, and/or trade secrets.

(b)

In order to determine the rights of Executive and the Bank in any idea, discovery, invention, improvement, software, writing or other material, and to insure the protection of the same, Executive agrees that during the Executive’s employment, and for one (1) year after termination of Executive’s employment with the Bank, Executive will disclose immediately and fully to the Bank any idea,

discovery, invention, improvement, software, writing or other material or design conceived, made or developed by Executive solely or jointly with others. The Bank agrees to keep any such disclosures confidential. Executive also agrees to record descriptions of all work in the manner directed by the Bank and agrees that all such records and copies, samples and experimental materials will be the exclusive property of the Bank. Executive agrees that at the request of and without charge to the Bank, but at the Bank’s expense, the Executive will execute a written assignment of the idea, discovery, invention, improvement, software, writing or other material or design to the Bank and will assign to the Bank any application for letters patent or for trademark registration made thereon, and to any common-law or statutory copyright therein; and that Executive will do whatever may be necessary or desirable to enable the Bank to secure any patent, trademark, copyright, or other property right therein in the United States and in any foreign country, and any division, renewal, continuation, or continuation in part thereof, or for any reissue of any patent issued thereon. In the event the Bank is unable, after reasonable effort, and in any event after ten (10) business days, to secure Executive’s signature on a written assignment to the Bank of any application for letters patent or to any common-law or statutory copyright or other property right therein, whether because of the Executive’s physical or mental incapacity or for any other reason whatsoever, the Executive irrevocably designates and appoints the Corporate Secretary of the Bank as Executive’s attorney-in-fact to act on Executive’s behalf to execute and file any such application and to do all other lawfully permitted acts to further the prosecution and issuance of such letters patent, copyright or trademark.

(c)

Executive acknowledges that, to the extent permitted by law, all work papers, reports, documentation, drawings, photographs, negatives, tapes and masters therefor, prototypes and other materials (hereinafter, “items”) (including, without limitation, any and all such items generated and maintained on any form of electronic media) generated by Executive during Executive’s employment with the Bank shall be considered a “work made for hire” and that ownership of any and all copyrights in any and all such items shall belong to the Bank. The item will recognize the Bank as the copyright owner, will contain all proper copyright notices, e.g., “(creation date) the Bank, a Texas banking association, All Rights Reserved.” and will be in condition to be registered or otherwise placed in compliance with registration or other statutory requirements throughout the world.

7.12

COMMUNICATION OF CONTENTS OF AGREEMENT

During Executive’s employment with the Bank and for one (1) year thereafter, Executive will communicate the contents of this Section 7 of this Agreement to any person, firm, association, partnership, corporation or other entity that Executive intends to be employed by, associated with, or represent.

7.13

RELIEF

Executive acknowledges and agrees that the remedy at law available to the Bank for breach of any of Executive’s obligations under this Agreement would be inadequate. Executive therefore agrees that, in addition to any other rights or remedies that the Bank may have at law or in equity, temporary and permanent injunctive relief may be granted in any proceeding which may be brought to enforce any provision contained in Sections 7.2, 7.3, 7.9, 7.10, 7.11 and 7.12 inclusive, of this Agreement, without the necessity of proof of actual damage.

7.14

REASONABLENESS

Executive acknowledges that Executive’s obligations under this Agreement are reasonable in the context of the nature of the Bank’s business and the competitive injuries likely to be sustained by the Bank if Executive were to violate such obligations and that these obligations do not place an undue burden on Executive. It is the desire and intent of the parties hereto that the provisions of this Agreement shall be enforced to the fullest extent legally-permissible. Accordingly, if any particular provision(s) of this

Agreement shall be adjudicated to be invalid or unenforceable, the court may modify or sever such provision(s), such modification or deletion to apply only with respect to the operation of such provision(s) in the particular jurisdiction in which such adjudication is made. In addition, if any one or more of the provisions contained in this Agreement shall for any reason be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting and reducing it, so as to be enforceable to the extent compatible with the applicable law as it shall then appear. The remaining provisions of this Agreement shall remain in full force and effect.

NON-DISPARAGEMENT

Executive agrees and covenants that Executive will not at any time make, publish or communicate to any person or entity or in any public forum any defamatory or disparaging remarks, comments or statements concerning the Bank or its businesses, or any of its employees, officers, and existing and prospective customers, suppliers, investors and other associated third parties.

This Section 8 does not, in any way, restrict or impede Executive from exercising protected rights to the extent that such rights cannot be waived by agreement or from complying with any applicable law or regulation or a valid order of a court of competent jurisdiction or an authorized government agency, provided that such compliance does not exceed that required by the law, regulation or order. Executive shall (if lawful) promptly provide written notice of any such order to the Bank. In addition, this Section 8 does not in any way restrict or impede Executive from making good faith statements in internal performance discussions or reviews or denying false statements made by others.

ACKNOWLEDGEMENT

Executive acknowledges and agrees that: (a) the services to be rendered by Executive to the Bank are of a special and unique character; (b) Executive will obtain knowledge and skill relevant to the Bank’s industry, methods of doing business and marketing strategies by virtue of Executive’s employment; and (c) the restrictive covenants and other terms and conditions of this Agreement are reasonable and reasonably necessary to protect the legitimate business interest of the Bank.

Executive further acknowledges that: (x) the amount of Executive’s compensation reflects, in part, Executive’s obligations and the Bank’s rights under Section 7 and Section 8 of this Agreement; (y) Executive has no expectation of any additional compensation, royalties or other payment of any kind not otherwise referenced herein in connection herewith; and (z) Executive will not be subject to undue hardship by reason of Executive’s full compliance with the terms and conditions of Section 7 and Section 8 of this Agreement or the Bank’s enforcement thereof.

10.

REMEDIES

If, at the time of enforcement of any of the obligations in Section 7, a court shall hold that the duration, scope, or area restrictions are unreasonable, the parties agree that the maximum duration, scope, or area reasonable, as determined by the court, shall be substituted and that the court shall enforce the obligations as modified.

In the event of a breach or threatened breach by the Executive of Section 7 and Section 8 of this Agreement, Executive hereby consents and agrees that the Bank shall be entitled to seek, in addition to other available remedies, a temporary or permanent injunction or other equitable relief against such breach or threatened breach from any court of competent jurisdiction, without the necessity of showing any actual damages or that money damages would not afford an adequate remedy, and without the necessity of posting any bond or other security. The aforementioned equitable relief shall be in addition to, not in lieu of, legal

remedies, monetary damages or other available forms of relief. In addition, in the event of an alleged breach or violation by Executive of the obligations in Section 7, the non-compete period shall be tolled until such breach or violation has been cured.

11.

ARBITRATION

Subject to Section 10( Remedies), Executive and the Bank agree to submit any controversy or claim arising out of this Agreement or otherwise relating to Executive’s employment with the Bank, the Bank’s parent(s), or any of the Bank’s subsidiaries or the termination of such employment (including, but not limited to any claims of breach of contract, wrongful termination or age, sex, race or other discrimination) exclusively to confidential binding arbitration before a single arbitrator. Any such arbitration will be fully and finally resolved in binding arbitration in a proceeding in Texas in accordance with the Federal Arbitration Act and the National Rules for the Resolution of Employment Disputes of the American Arbitration Association which are then in effect before a single arbitrator. Judgment upon any award rendered by the arbitrator may be entered in any court having jurisdiction thereof. Each party shall be responsible for payment of its reasonable fees of attorneys, professionals and experts and other costs and fees incurred in connection with any arbitration relating to the interpretation or enforcement of any provision of this Agreement.

12.

PUBLICITY

During the Employment Term and thereafter, Executive hereby consents to any and all reasonable and customary uses and displays, by the Bank and its agents, representatives and licensees, of the Executive’s name, voice, likeness, image, appearance and biographical information in, on or in connection with any pictures, photographs, audio and video recordings, digital images, websites, television programs and advertising, other advertising and publicity, sales and marketing brochures, books, magazines, other publications, CDs, DVDs, tapes and all other printed and electronic forms and media throughout the world, at any time during the period of Executive’s employment by the Bank, for all legitimate commercial and business purposes of the Bank (“Permitted Uses”), without royalty, payment or other compensation to Executive.

13.

GOVERNING LAW; JURISDICTION AND VENUE

This Agreement, for all purposes, shall be construed in accordance with the laws of Texas without regard to conflicts of law principles. Subject to Section 11, any action or proceeding by either of the parties to enforce this Agreement shall be brought only in Harris County, Texas. The parties hereby irrevocably submit to the exclusive jurisdiction of such courts and waive the defense of inconvenient forum to the maintenance of any such action or proceeding in such venue. In any such proceeding, each of the parties hereby knowingly and willingly waives and surrenders such party’s right to trial by jury and agrees that such litigation shall be tried to a judge sitting alone as the trier of both fact and law, in a bench trial, without a jury.

14.

ENTIRE AGREEMENT

Unless specifically provided herein, this Agreement contains all of the understandings and representations between Executive and the Bank pertaining to the subject matter hereof and supersedes all prior and contemporaneous understandings, agreements, representations and warranties, both written and oral, with respect to such subject matter; provided, however, that if Executive and the Bank enter into a separate restrictive covenant agreement and the provisions of that agreement conflict with the provisions in this Agreement, the provision that entitles the Bank to the broadest relief under applicable law shall control; provided, further, that, with the exception of Section 5.8 (Section 280G), nothing in this Agreement shall

supersede, limit or in any way affect any rights Executive may have under any employee benefit plan, program or agreement.

The parties mutually agree that this Agreement can be specifically enforced in court and can be cited as evidence in legal proceedings alleging breach of this Agreement.

16.

SEVERABILITY

Should any provision of this Agreement be held by a court of competent jurisdiction to be enforceable only if modified, or if any portion of this Agreement shall be held as unenforceable and thus stricken, such holding shall not affect the validity of the remainder of this Agreement, the balance of which shall continue to be binding upon the parties with any such modification to become a part hereof and treated as though originally set forth in this Agreement.

The parties further agree that any such court is expressly authorized to modify any such unenforceable provision of this Agreement in lieu of severing such unenforceable provision from this Agreement in its entirety, whether by rewriting the offending provision, deleting any or all of the offending provision, adding additional language to this Agreement or by making such other modifications as it deems warranted to carry out the intent and agreement of the parties as embodied herein to the maximum extent permitted by law.

The parties expressly agree that this Agreement as so modified by the court shall be binding upon and enforceable against each of them. In any event, should one or more of the provisions of this Agreement be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions hereof, and if such provision or provisions are not modified as provided above, this Agreement shall be construed as if such invalid, illegal or unenforceable provisions had not been set forth herein.

Except as otherwise provided in Section 2 of this Agreement, if your employment or service with the Company and its Subsidiaries ends for any reason, then you will immediately forfeit, and the Company will immediately re-acquire, all then unvested Restricted Shares for no consideration. The Company determines when your employment or service terminates for this purpose and all purposes under the Plan, and its determination is conclusive and binding on all Persons.

Restrictions on Transfer. The Restricted Shares covered by this Award shall not be sold, assigned, transferred, disposed of, pledged or otherwise hypothecated by you (other than to the Company) unless and until they become vested and cease to be Restricted Shares pursuant to Section 2 above. Any attempted sale, assignment, transfer, disposition, pledge or hypothecation of the Restricted Shares in violation of this Agreement shall be void and of no effect and the Company shall have the right to disregard the same on its books and records and issue “stop transfer” instructions to its transfer agent.

Escrow. By your acceptance of the Award, you will be deemed to appoint, and do so appoint, the Secretary of the Company or such other escrow holder as the Committee may appoint to hold the Restricted Shares in escrow as your attorney(s)-in-fact to effect any transfer of unvested forfeited Restricted Shares (or Restricted Shares otherwise reacquired by the Company hereunder) to the Company as may be required pursuant to the Plan or this Agreement and to execute such documents as the Company or such representatives deem necessary or advisable in connection with any such transfer.

Removal of Notations. As soon as administratively practicable after the vesting of any Restricted Shares subject to the Award pursuant to Section 2 hereof and your satisfaction of the required Tax Withholdings pursuant to Section 9, the Company shall remove the notations on any Restricted Shares subject to the Award which have vested. You (or your beneficiary or personal representative in the event of your death or incapacity, as the case may be) shall deliver to the Company any representations or other documents or assurances required by the Company.

Rights as Shareholder; Dividend Equivalents. Except as otherwise provided herein, upon the Date of Grant you shall have all the rights of a shareholder of the Company with respect to the Restricted Shares including, without limitation, voting rights and rights to receive any cash or stock dividends; provided, however, that the aggregate amount of any cash or stock dividends shall be held by the Company, without interest thereon, and paid to you as soon as practicable following the date on which the Restricted Shares to which such dividends relate vest. Any dividends held by the Company on Restricted Shares that do not vest shall be forfeited and retained by the Company.

Section 83(b) Election. If you make an election under Section 83(b) of the Code to be taxed with respect to the Restricted Shares as of the date of transfer of the Restricted Shares rather than as of the date or dates upon which you would otherwise be taxable under Section 83(a) of the Code, you hereby agree to deliver a copy of such election to the Company promptly after filing such election with the Internal Revenue Service.

Tax Obligations.

(a)

Withholding Requirements. The notations on the Restricted Shares will not be removed by the Company unless and until you make satisfactory arrangements (as determined by the Committee) for the payment of the amount the Company deems appropriate to satisfy its (or its Subsidiary’s) current or future obligation to withhold federal, state or local income or other taxes that you incur as a result of the grant or vesting of the Restricted Shares (the “Tax Withholdings”). If you fail to make satisfactory arrangements for the payment of any Tax Withholdings under this Agreement, the Company may refuse to remove the notations on the Restricted Shares, to the extent permitted by applicable laws.

(b)

Withholding. With respect to any required Tax Withholdings, you may: (i) direct the Company to withhold from the Restricted Shares a number of shares of Common Stock to satisfy such Tax Withholdings, which determination will be based on the Fair Market Value of the shares of Common Stock at the time such determination is made; (ii) deliver to the Company shares of Common Stock sufficient to satisfy such withholding, based on the Fair Market Value of the shares of Common Stock at the time such determination is made; (iii) provide for withholding from proceeds of the sale of shares of Common Stock issuable or issued to you pursuant to this Award through a voluntary broker-assisted sale arranged by the Company; or (iv) deliver cash to the Company sufficient to satisfy such withholding obligations. If you desire to elect to use the withholding option described in subparagraph (i), (ii) or (iii), you must make the election at the time and in the manner the Company prescribes. The Committee, in its discretion, may deny your request to satisfy tax withholding using a method described under subparagraph (i), (ii) or (iii). In the event the Company determines that the aggregate Fair Market Value of the shares of Common Stock withheld as payment of any Tax Withholdings is insufficient to discharge its tax withholding obligation, then you must pay to the Company, in cash, the amount of that deficiency immediately upon the Company’s request.

The Company may require you or your legal representative, heir, legatee or distributee, as a condition precedent to such payment or issuance, to execute a release and receipt therefor in such form as it shall determine.
