AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AGREEMENT

Exhibit 10.1

AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AGREEMENT

This Amended and Restated Executive Employment Agreement (this “Agreement”) is entered into on December 18, 2014 by and between Texas Capital Bancshares, Inc. (“TCBI”), which is the holding company of Texas Capital Bank, N.A. (“TCB”)(TCBI and TCB shall be collectively referred to herein as the “Company”), and Keith Cargill (“Executive”). The Company and Executive are referred to in this Agreement as the “Parties.” This Agreement amends and restates, in its entirety, the Executive Employment Agreement entered into on July 10, 2013, by and between the Company and Executive (the “Prior Agreement”). In consideration of the mutual covenants and promises contained in this Agreement, the Parties agree as follows:

1. Agreement to Employ. The Company desires to continue to employ Executive as President and Chief Executive Officer of TCBI and TCB. The Company and Executive desire to enter into this Agreement to, among other things, set forth the terms of Executive’s employment with the Company.

2. Term of Agreement. This Agreement shall be binding upon and enforceable against the Company and Executive immediately when both parties execute the Agreement. The Agreement’s stated term and the employment relationship created hereunder will begin on December 19, 2014 (the “Effective Date”), and will remain in effect for one (1) year thereafter, unless earlier terminated in accordance with Agreement Section 7 (the “Initial Employment Term”). This Agreement shall be automatically renewed for successive one (1) year terms after the Initial Employment Term (each, a “Renewal Term”), unless terminated by either party upon written notice given at least thirty (30) days before the end of the Initial Employment Period or any Renewal Term, or unless earlier terminated in accordance with Agreement Section 7. The period during which Executive is employed under this Agreement (including any Renewal Term) will be referred to as the “Employment Period.”

3. Surviving Agreement Provisions. Notwithstanding any provision of this Agreement to the contrary, the Parties’ respective rights and obligations under Agreement Sections 6, 7, 8, and 10(b), 10(c), and 10(e) shall survive any termination or expiration of this Agreement or the termination of Executive’s employment for any reason whatsoever.

4. Services to be Provided by Executive.

a. Position and Responsibilities. Subject to the Agreement’s terms, Executive agrees to continue to serve as President and Chief Executive Officer of TCBI and TCB for all periods during the Employment Term, and to perform satisfactorily the following duties: (i) hire employees, subject to the Company’s approval, as necessary to facilitate Company operations, including the development of a positive work environment to maximize employee performance; (ii) set levels of customer service expectations for Company personnel and ensure that customers receive quality service; (iii) promote the Company’s best interests; and (iv) perform any other duties that the Board may assign Executive from time to time. During the Employment Period, Executive will devote his undivided loyalty to the Company and devote all of his skill, knowledge and working time (except for (x) reasonable vacation time and absence for sickness or similar disability, and (y) to the extent that it does not interfere with the performance of Executive’s duties under this Agreement, (A) such reasonable time as may be devoted to service on boards of

directors and the fulfillment of civic responsibilities, charitable or religious activities, and (B) such reasonable time as may be necessary from time to time for personal financial matters) to the conscientious performance of his duties and responsibilities under the Agreement. Executive shall report directly to the Board, and members of the Company’s senior management team, including, without limitation, members holding the title of Chief Financial Officer, Chief Operating Officer, Chief Lending Officer, Chief Credit Officer, or Chief Risk Officer, shall report directly to Executive, provided that the Board may modify the reporting structure of a member of the Company’s senior management team if, when considering industry-wide best practices, the Board determines, in good faith , that it is appropriate for said member to report directly to the Board, provided further that such change in reporting structure shall not constitute “Good Reason” as defined in Section 7(d)(i) below. The location at which Executive performs his duties will not be relocated more than fifty (50) miles from the Company’s offices where Executive performs the majority of Executive’s work on the date of this Agreement without Executive’s written consent.

b. Executive’s Employment Representations. Executive represents to the Company that he (i) will not serve as a member of any board of directors, or as a trustee of, or in any manner be affiliated with, any present or future agency or organization (except for civic, religious, and not for profit organizations and the board of directors on which Executive serves as a board member as of the Effective Date) without the consent of the Company; (ii) will serve as an Executive of the Company; (iii) will not, directly or indirectly, have any interest in, or perform any services for, any business competing with or similar in nature to the Company’s business. Executive further represents to the Company that (i) he is not violating and will not violate any contractual, legal, or fiduciary obligations or burdens to which Executive is subject by entering into this Agreement or providing services under the Agreement’s terms; and (ii) Executive is under no contractual, legal, or fiduciary obligation or burden that reasonably may be expected to interfere with Executive’s ability to perform services under the Agreement’s terms.

5. Compensation for Services. For all services rendered by Executive pursuant to this Agreement, the Company shall pay to Executive, and Executive shall accept as full compensation hereunder the following:

a. Base Salary. Executive shall receive an annual base salary of $625,000. Executive’s salary shall be paid semi-monthly and subject to all appropriate federal and state withholding taxes and shall be payable in accordance with the normal payroll procedures of the Company. The Board shall annually review such base salary, provided, however, that Executive’s base salary may not be reduced without Executive’s consent.

b. Benefits and Perquisites. Executive shall be entitled to participate in the benefit plans provided by the Company for all employees generally, and for executive employees of the Company. The Company shall be entitled to change or terminate such plans in its sole discretion at any time. The Parties acknowledge that at the initial date of this Agreement the fringe benefits provided to Executive include a 401(k) plan, health, dental, life, short and long disability insurance, and reimbursement of certain reasonable out-of-pocket expenses in accordance with the policies and procedures of the Company. Any reimbursement of expenses made under this Agreement shall only be made for eligible expenses incurred during the Initial Employment Term

2

or Renewal Term, and no reimbursement of any expense shall be made by the Company after December 31st of the year following the calendar year in which the expense was incurred. The amount eligible for reimbursement under this Agreement during a taxable year may not affect expenses eligible for reimbursement in any other taxable year, and the right to reimbursement under this Agreement is not subject to liquidation or exchange for another benefit.

c. Discretionary Bonuses. The Company’s Board shall establish an incentive bonus plan for its key executives based on various targets and performance criteria to be established by the Board in its sole discretion. Executive shall be permitted to participate in such plan, if adopted by the Board. The evaluation of the performance of Executive as measured by the applicable targets and the awarding of applicable bonuses, if any, shall be at the Board’s sole discretion. The annual discretionary bonus may be awarded in whole or in part, based on the level of incentive bonus plan performance criteria achieved by Executive, in the Board’s sole judgment.

If Executive terminates his employment and this Agreement without Good Reason, as defined in Agreement Section 7(d), or if the Company terminates this Agreement and Executive’s employment at any time for Cause, as defined in Agreement Section 7(b), Executive will not be paid any discretionary bonus pursuant to this Agreement Section 5(c), in whole or in part, for the year in which such termination occurs. The Parties agree that any bonus payable pursuant to this Agreement Section 5(c) shall be paid no later than March 15 of the calendar year immediately following the calendar year in which such bonus is no longer subject to a substantial risk of forfeiture.

d. Equity Compensation. The Company establishes equity-based incentives for its executives from time to time under certain stock-based compensation plans as the Company may establish from time to time (collectively, the “Plans”). The Company may, but is not obligated to, make grants of equity-based incentive compensation to Executive pursuant to the terms of the Plans.

6. Protective Covenants.

a. Existence of Fiduciary Relationship. Executive recognizes and agrees that his employment with the Company places him in an executive position involving the highest trust and confidence. Accordingly, Executive agrees that he owes the Company a duty of loyalty, confidence, and trust. This duty, in turn, gives rise to a fiduciary relationship between Executive and the Company.

b. Confidential Information. Executive acknowledges and agrees that the Company has developed and will continue to develop unique concepts, lending practices, sales presentations, marketing programs, marketing strategies, business practices, methods of operation, pricing information, cost information, trademarks, licenses, technical information, proprietary information, computer software programs, tapes and disks concerning its operations systems, customer lists, customer leads, documents identifying past, present and future customers, customer profile and preference data, hiring and training methods, investment policies, financial and other confidential, proprietary and/or trade secret information concerning its operations and expansion plans (“Confidential Information”). The Confidential Information includes, without

3

limitation, information about the Company’s business, proprietary, and technical information not known to others that could have economic value to others if improperly disclosed. Confidential Information also means any information the Company discloses to Executive, either directly or indirectly, in writing, orally or by inspection of tangible objects, including, without limitation, information and technical data contained in the Company’s manuals, booklets, publications and materials, equipment of every kind and character, as well as documents, prototypes, samples, prospects, inventions, product ideas, know-how, processes, plans (including without limitation, marketing plans and strategies), specifications, designs, techniques, technology, formulas, software, improvements, forecasts, and research.

Therefore, Executive agrees that the following protective covenants constitute a reasonable and appropriate means, consistent with the best interests of both Executive and the Company, to protect the Company and its affiliate companies (including, without limitation, TCBI, TCB and BankDirect) against damage due to loss or disclosure of Confidential Information and shall apply to and be binding upon Executive as provided in this Agreement:

c. Access To And Agreement Not To Disclose Confidential Information. During Executive’s Employment Period, the Company agrees to provide Executive with some or all of the Company’s Confidential Information to which Executive has not previously had access and of which Executive has not had previous knowledge. By executing this document, Executive agrees that the Confidential Information constitutes valuable, special and unique Company assets, developed at the Company’s great expense, the unauthorized use or disclosure of which would cause irreparable harm to the Company. Executive understands and acknowledges that the Company is engaged in a highly specialized and competitive industry; that the Company relies heavily on information, data, programs, and processes it has developed and acquired; and that competitors can reap potential or real economic benefits from the possession of the Confidential Information that is otherwise not available to the competitors. Executive understands and acknowledges, therefore, that the protection of the Company’s Confidential Information constitutes the Company’s legitimate business interest. Executive acknowledges that the Confidential Information is the exclusive property of Company, and Executive will hold the Confidential Information in trust and solely for Company’s benefit. Executive further acknowledges that the Confidential Information includes “trade secrets” under Texas law (and, including, without limitation, the Texas Trade Secrets Act) and, in addition to the other protections provided in this Agreement, all trade secrets will be accorded the protections and benefits under Texas law and any other applicable law. Executive waives any requirement that the Company submit proof of any trade secret’s economic value or post a bond or other security should the need arise.

In exchange for the Company’s promise to provide Executive with some or all of the Company’s Confidential Information to which Executive has not previously had access and of which Executive has not had previous knowledge, Executive agrees that he will not, either during the period of his employment with the Company or at any time thereafter, use for Executive’s benefit or the benefit of another, or disclose, disseminate, or distribute to anyone, including, without limitation, any individual, person, firm, corporation, or other entity, or publish, or use for any purpose, any of the Confidential Information (whether acquired, learned, obtained, or developed by Executive alone or in conjunction with others), except (i) as properly required in the ordinary course of the Company’s business or as the Company directs and authorizes; (ii) as required by applicable law (so long as, to the extent reasonable and practicable, reasonable prior notice of such disclosure is given to the Company); (iii) to the extent such information is available to or

4

known by the public (other than as a result of disclosure in violation hereof); or (iv) to enforce his rights under this Agreement. Executive agrees that he will take all reasonable measures to protect the secrecy of and avoid disclosure and unauthorized use of the Confidential Information. Executive also agrees to notify the Company immediately in the event of any unauthorized use or disclosure of the Company’s Confidential Information.

d. Use of Confidential Information During Employment. Except as may be required of Executive to perform his job duties, Executive further agrees that in the course of his Company employment, Executive will not (i) remove from any Company office any documents, electronically stored information, or related items that contain Confidential Information, including, without limitation, computer discs, recordings, or other storage or archival systems or devices, including copies; or (ii) place or save any Confidential Information on any computer or electronic storage system that is not Company property. All Confidential Information, and all memoranda, notes, records, drawings, documents, electronically stored information, or other writings whatsoever made, compiled, acquired, or received by Executive at any time during his employment with the Company, including during the term of this Agreement, arising out of, in connection with, or related to any Company activity or business, including, without limitation, the customers, vendors, third parties, or others with whom the Company has a business relationship, the arrangements of the Company with such parties, and the pricing and expansion policies and strategy of the Company, are, and shall continue to be, the Company’s sole and exclusive property.

e. Protective Covenant – Non-Competition. Executive agrees that to protect the Company’s Confidential Information and goodwill, and in consideration for the grants to Executive under the Plans referenced in Agreement Section 5(d), it is necessary to enter into the following protective covenants, which are ancillary to the enforceable promises between the Company and Executive in the other Agreement Sections. During Executive’s employment with the Company, and for a one-year period after the date Executive’s employment is terminated by the Company for any reason, or if Executive resigns for any reason, Executive shall not, without the Company’s prior written consent, directly or indirectly: (i) compete for or solicit business for or on behalf of any person or business entity operating a state or national bank or company providing similar services with a place of business in the State of Texas; (ii) own, operate, participate in, consult with, undertake any employment with, or have any interest in any entity with a place of business in the State of Texas related to the operation of a state or national bank or company providing similar services, except that Executive may own publicly traded stock for investment purposes only in any company in which Executive owns less than 5% of the voting equity; or (iii) use or rely on in any competition, solicitation, or marketing effort any Confidential Information, any proprietary list, or any information concerning any customer of the Company.

Executive also acknowledges that the geographic boundaries, scope of prohibited activities, and the duration of the provisions in these Protective Covenants are reasonable and are no broader than are necessary to protect the Company’s legitimate business interests. These Protective Covenants shall survive the termination of Executive’s employment and can be revoked or modified only by a writing signed by the Parties that specifically states an intent to revoke or modify this provision. Executive acknowledges that the Company would not employ him or provide him with access to its Confidential Information but for his Protective Covenants or promises contained in this Agreement Section 6. Executive further agrees that during the non-competition term, he shall immediately notify the Company in writing of any employment, work, or business he undertakes with or on behalf of any person (including himself) or entity.

5

f. Protective Covenants – Non-Solicitation of Employees or Customers. Executive agrees that during his employment, and for a period of one year following the termination or resignation of his employment, for whatever reason, that neither he nor any individual, partner(s), or company, corporation, or other entity or business with which he is in any way affiliated, including, without limitation, any partner, limited partner, member, director, officer, shareholder, employee, or agent of any such entity or business, will request, induce or attempt to influence, directly or indirectly, any employee of the Company to terminate employment with the Company. Executive agrees that for a period of one year following the termination or resignation of his employment, for whatever reason, whether involuntary or voluntary, he shall not, directly or indirectly, as an owner, stockholder, director, employee, partner, agent, broker, consultant or other participant solicit a customer or prospective customer, or accept any business from a customer or prospective customer with whom he has done business or with whom he has had contact during the last twelve (12) months of Executive’s employment with the Company.

g. Return of Documents. In the event of the termination of Executive’s employment for any reason or Executive’s resignation or employment separation for any reason, Executive will deliver to the Company all non-personal documents and data of any nature, and in whatever medium, concerning Executive’s employment with the Company or any of its subsidiaries or affiliates. Executive agrees that he will not take with him any Company property, documents, or data of any description or any reproduction thereof, including summaries or notes regarding same, or any documents containing or relating to any Company proprietary or Confidential Information.

h. Validity. The terms and provisions of this Agreement Section 6 are intended to be separate and divisible provisions and if, for any reason, any one or more of them is held to be invalid or unenforceable, neither the validity nor the enforceability of any other provision of this Agreement will be affected. If, for any reason, any court of competent jurisdiction finds any provisions of Agreement Section 6 unreasonable in duration or geographic scope or otherwise, Executive and the Company agree that the restrictions and prohibitions contained in Agreement Section 6 shall be effective to the fullest extent allowed under applicable law.

i. Work Product. For purposes of this Agreement Section 6, “Work Product” shall mean all intellectual property rights, including all trade secrets, U.S. and international copyrights, patentable inventions, discoveries and other intellectual property rights in any programming, design, documentation, technology, or other work product that is created in connection with Executive’s work. In addition, all rights in any preexisting programming, design, documentation, technology, or other Work Product provided to the Company during Executive’s employment shall automatically become part of the Work Product hereunder, whether or not it arises specifically out of Executive’s “Work.” For purposes of this Agreement, “Work” shall mean (i) any direct assignments and required performance by or for the Company, and (ii) any other productive output that relates to the business of the Company and is produced during the course of Executive’s employment or engagement by the Company. For this purpose, Work may be considered present even after normal working hours, away from the Company’s premises, on an unsupervised basis, alone or with others. Unless otherwise approved in writing by the Company’s Board, this Agreement shall apply to all Work Product created in connection with all Work conducted before or after the date of this Agreement.

The Company shall own all rights in the Work Product. To this end, all Work Product shall be considered work made for hire for the Company. If any of the Work Product may not, by operation of law or agreement, be considered Work made by Executive for hire for the Company (or if ownership of all rights therein do not otherwise vest exclusively in the Company

6

immediately), Executive agrees to assign, and upon creation thereof does hereby automatically assign, without further consideration, the ownership thereof to the Company. Executive hereby irrevocably relinquishes for the benefit of the Company and its assigns any moral rights in the Work Product recognized by applicable law. The Company shall have the right to obtain and hold, in whatever name or capacity it selects, copyrights, registrations, and any other protection available in the Work Product.

Executive agrees to perform upon the request of the Company, during or after Executive’s Work or employment, such further acts as may be necessary or desirable to transfer, perfect, and defend the Company’s ownership of the Work Product, including by (i) executing, acknowledging, and delivering any requested affidavits and documents of assignment and conveyance, (ii) obtaining and/or aiding in the enforcement of copyrights, trade secrets, and (if applicable) patents with respect to the Work Product in any countries, and (iii) providing testimony in connection with any proceeding affecting the rights of the Company in any Work Product. In the event that Executive is required to perform the services described in this paragraph after his employment with the Company has terminated, Executive will be reasonably compensated for actual time spent providing such services.

Executive warrants that his Work for the Company does not and will not in any way conflict with any obligations Executive may have with any prior employer or contractor. Executive also agrees to develop all Work Product in a manner that avoids even the appearance of infringement of any third party’s intellectual property rights.

j. Survival of Covenants. Each covenant of Executive set forth in this Agreement Section 6 shall survive the termination of this Agreement and Executive’s employment for any reason and shall be construed as an agreement independent of any other provision of this Agreement, and the existence of any claim or cause of action of Executive against the Company whether predicated on this Agreement or otherwise shall not constitute a defense to the enforcement by the Company of said covenant. No modification or waiver of any covenant contained in this Agreement Section 6 shall be valid unless such waiver or modification is approved in writing by the Company’s Board.

k. Remedies. In the event of a breach, violation or threatened breach or violation by Executive of any provision of this Agreement Section 6, Executive agrees that the Company shall be entitled to relief by temporary restraining order, temporary injunction, or permanent injunction or otherwise, in addition to other legal and equitable relief to which it may be entitled, including any and all monetary damages which the Company may incur as a result of said breach, violation or threatened breach or violation. The Company may pursue any remedy available to it concurrently or consecutively in any order as to any breach, violation, or threatened breach or violation, and the pursuit of one of such remedies at any time will not be deemed an election of remedies or waiver of the right to pursue any other of such remedies as to such breach, violation, or threatened breach or violation, or as to any other breach, violation, or threatened breach or violation.

l. Tolling. Additionally, if Executive violates any of the Protective Covenants contained in Agreement Sections 6(e-f), the time period shall be suspended with respect to the restriction that has been violated and will not run in favor of Executive from the time of the commencement of any such violation until the time when Executive cures the violation to the Company’s satisfaction.

7

7. Termination of Agreement. The employment relationship between Executive and the Company created hereunder shall terminate before the expiration of the stated term of this Agreement upon the occurrence of any one of the following events:

a. Death or Permanent Disability. This Agreement, and Executive’s employment, shall be terminated effective on the death or permanent disability of Executive. However, Executive shall be entitled to leaves of absence from the Company in accordance with the policy of the Company generally applicable to executives for illness or temporary disabilities for a period or periods not exceeding three (3) months on a cumulative basis in any calendar year, and his status as an Executive shall continue during such periods. However, if Executive qualifies for short term disability payments under the Company’s standard short term disability plan during such leave, Executive shall apply to receive such short term disability payments. The Company shall supplement such short term disability payments so that Executive receives such monthly amounts, when combined with the short term disability payments, equal to Executive’s monthly salary then in effect as set forth in Agreement Section 5. If Executive is incapacitated due to physical or mental illness and such incapacity prevents Executive from satisfactorily performing his duties for the Company on a full time basis for six (6) months or more, the Company may terminate this Agreement upon thirty (30) days written notice. Upon the termination of this Agreement due to the death or permanent disability of Executive, Executive or his estate (as the case may be) shall be entitled to compensation as provided in Agreement Section 8(a) below. If during the period of Executive’s incapacity, Executive is deemed to have incurred a “separation from service” under Section 409A because there is no reasonable expectation that he will return to perform services for the Company, Executive shall be entitled, as a disability benefit, to continuation of his monthly salary as described in Agreement Section 5(a) above until the date on which this Agreement is terminated under this Agreement Section 7(a) (the “Disability Period”), provided, however, that such payments shall be reduced on a dollar-for-dollar basis by the amount of bona fide disability pay (within the meaning of Treas. Reg. section 1.409A-1(a)(5)) received or receivable by Executive during the Disability Period, provided such disability payments are made pursuant to a plan sponsored by the Company that covers a substantial number of employees of the Company and was established prior to the date Executive incurred a permanent disability, and further provided that such reduction does not otherwise affect the time of payment of Executive’s base salary pursuant to this Agreement Section 7(a).

b. Termination for Cause. The Company shall have the option to terminate Executive’s employment during the Employment Period, effective upon written notice of such termination to Executive, for Cause as the Company determines. Under the Agreement, termination for “Cause” means the Company’s termination of Executive’s employment upon the occurrence of any of the following events:

8

The Company shall provide Executive with a written notice of termination (and in the case, of an event described in (ii) and (viii), thirty (30) days within which Executive may cure such event constituting “Cause” before such termination is effective) which can be provided on the date of termination. In the event Executive’s employment is terminated for Cause under this Agreement, Executive shall be entitled to the compensation provided in Agreement Section 8(a) below.

c. Termination by the Company with Notice. The Company may terminate this Agreement without Cause at any time upon thirty (30) days written notice to Executive, during which period Executive shall not be required to perform any services for the Company other than to assist the Company in training his successor and generally preparing for an orderly transition; provided, however, that Executive shall be entitled to compensation upon such termination as provided in Agreement Sections 8(a) and 8(b) below.

d. Termination by Executive For Good Reason. Executive shall be entitled to terminate this Agreement at any time for Good Reason. Under this Agreement, “Good Reason” shall mean the occurrence of any of the following events:

9

Executive shall give the Company thirty (30) business days’ notice of an intent to terminate this Agreement for “Good Reason” as defined in this Agreement Section 7(d), and provide the Company with thirty (30) calendar days after receipt of such notice from Executive to remedy the alleged violation of Subsections 7(d)(i)-(iii). In the event the Company does not cure the violation, if Executive does not terminate this Agreement within sixty (60) days following the last day of the Board’s cure period, the occurrence of the violation shall not subsequently serve as Good Reason for Executive to terminate this Agreement. In the event Executive terminates his employment for Good Reason hereunder, Executive shall be entitled to the compensation provided in Agreement Sections 8(a) and 8(b) below.

e. Separation from Service. For purposes of this Agreement, including, without limitation, Agreement Sections 8 and 9, any references to a termination of Executive’s employment shall mean a “separation from service” as defined by Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”).

8. Compensation Upon Termination. Upon the termination of Executive’s employment under this Agreement before the expiration of the stated term in this Agreement for any reason, Executive shall be entitled to:

a. Compensation Upon Termination For Any Reason. Upon termination of Executive’s employment during the Employment Period before the expiration of the stated term hereof for any reason, Executive shall be entitled to the following within thirty (30) days of such termination:

10

b. Additional Compensation and Benefits Upon Termination Without Cause, With Notice or for Good Reason. If Executive’s employment hereunder terminates without “Cause” (as defined in Agreement Section 7(b) above), with notice pursuant to Agreement Section 7(c) above, or for “Good Reason” (as defined in Agreement Section 7(d) above) the Company shall, upon Executive’s execution of a general release of claims in favor of the Company (as described in Agreement Section 8(d)) and except as otherwise provided herein, provide to Executive in addition to the amounts set forth in Subsections 8(a) above:

The Company shall pay the severance amounts referenced in Agreement Section 8(b)(i-ii) in equal monthly installments for a period of twelve (12) months (“Severance Period”) in accordance with the Company’s regular payroll practices, beginning on the first payroll date coinciding with or next following the date that is sixty (60) days after the date of Executive’s termination. Executive shall have no obligation to mitigate any severance obligation of the Company under this Agreement by seeking new employment. The Company shall not be entitled to set off or reduce any severance payments owed to Executive under this Agreement by the amount of earnings or benefits received by Executive in future employment. Any payment made in accordance with this Agreement Section 8(a) shall be treated as a separate payment for purposes of Section 409A of the Code to the extent Section 409A of the Code applies to such payments.

Notwithstanding the foregoing, with respect to any stock options or other plans or programs in which Executive is participating at the time of termination of his employment, Executive’s rights and benefits under each such plan shall be determined in accordance with the terms, conditions, and limitations of the plan and any separate agreement executed by Executive which may then be in effect.

11

c. Forfeiture for Breach of Covenants. If, during the Severance Period, Executive is in breach of his Protective Covenants contained in Agreement Section 6, the Company shall not be obligated to pay any severance payments referenced herein, the Company’s severance obligations shall terminate and expire, and the Company shall have no further obligations to Executive under this Agreement or otherwise from and after the date of such breach and shall have all other rights and remedies available under this Agreement or any other agreement and at law or in equity.

d. Release. Payment of any of the amounts described in Agreement Section 8(b) is conditioned upon Executive’s execution of a Waiver and Release of Claims in the form attached hereto as Exhibit A relating to the period of Executive’s employment with the Company, within the twenty-one (21) day period following the end of Executive’s employment.

e. Shareholder Protection Provision. Notwithstanding anything to the contrary contained herein, in the event any of the following events occur, Executive only shall be entitled to receive the amounts described in Agreement Section 8(a), and, to the extent Executive’s Termination of Employment is without Cause or for Good Reason, Section 8(b)(i); provided, however, that “six (6) months” shall be substituted in lieu of “twelve (12) months” in Agreement Section 8(b)(i) above: (i) a complete dissolution or liquidation of the Company; (ii) a Title 11 bankruptcy proceeding, the appointment of a trustee or the conversion of a case involving the Company to a case under Chapter 7; or (iii) any distressed sale of the Company’s assets or stock (as defined below). For purposes of this Agreement, a “distressed sale of assets or stock” shall mean a sale effected for the purpose of avoiding bankruptcy or receivership, or any sale that is recommended to the Company by the Office of the Comptroller of Currency (or any other similar governmental agency with regulatory or oversight authority over the Company). In the event any amounts are received by Executive pursuant to this Agreement Section 8 that are calculated on the basis of the Company’s statement of earnings or gains, and if the Company is later required to prepare a restatement of its earnings or gains (other than a restatement caused by the retroactive application of accounting rules or other regulatory requirements) which the Board in good faith determines was due to the intentional misconduct of Executive or as to which the Board determines that Executive had actual knowledge of material inaccuracies in, Executive shall be required to reimburse the Company, net of taxes, for all severance payments made to Executive pursuant to this Agreement Section 8 that were calculated based on such statement of earnings or gains and Executive shall not be entitled to any additional payments pursuant to this Agreement Section 8 that would be calculated on the basis of a statement of earnings or gains. Notwithstanding the foregoing, in the event the Board in good faith determines that such restatement of the Company’s earnings or gains was not due to the intentional misconduct of Executive and that Executive had no actual knowledge of any material inaccuracies in such statement of earnings or gains, then Executive only shall be required to reimburse the Company, net of taxes, for the excess severance remuneration (as defined below). “Excess severance remuneration” shall mean the excess of the severance payments made to Executive pursuant to this Agreement Section 8 over the amount of severance payments calculated based on the Company’s statement of earnings as restated, as determined in the good faith discretion of the Board.

12

9. Compensation Upon Change in Control.

a. Change in Control. For purposes of this Agreement, a “Change in Control” of the Company shall be deemed to have occurred at such time as:

13

For purposes of subparagraphs (i), (ii) and (iii) above:

“Person” shall have the meaning given in Section 7701(a)(1) of the Code. Person shall include more than one Person acting as a group as defined by the Final Treasury Regulations issued under Section 409A of the Code.

“Affiliate” shall have the meaning set forth in Rule 12b-2 promulgated under Section 12 of the Securities Exchange Act of 1934, as amended.

The Company shall not be entitled to set off or reduce any severance payments owed to Executive under this Agreement Section 9 by the amount of earnings or benefits received by Executive in future employment.

d. Release. Payment of any of the amounts described in this Agreement Section 9 is conditioned upon Executive’s execution of a Waiver and Release of Claims in the form attached hereto as Exhibit A relating to the period of Executive’s employment with the Company, within the twenty-one (21) day period following the end of Executive’s employment.

10. Other Provisions.

a. Remedies. Each of the Parties to this Agreement will be entitled to enforce its rights under this Agreement, specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights existing in its favor.

15

b. Arbitration. If any dispute arises out of this Agreement or Executive’s employment or separation from employment with the Company for any reason, and the Parties to this Agreement cannot resolve the dispute, the dispute shall be submitted to final and binding arbitration. The arbitration shall be conducted in accordance with the American Arbitration Association’s (“AAA”) National Rules for the Resolution of Employment Disputes (“Rules”). If the Parties cannot agree to an arbitrator, an arbitrator will be selected through the AAA’s standard procedures and Rules. The Company and Executive shall share the costs of arbitration, unless the arbitrator rules otherwise. The Company and Executive agree that the arbitration shall be held in Dallas County, Texas. Arbitration of the Parties’ disputes is mandatory, and in lieu of any and all civil causes of action or lawsuits either party may have against the other arising out of the Agreement or Executive’s employment or separation from employment with Company, with the exception that the Company alone may seek a temporary restraining order and temporary injunctive relief in a court to enforce the protective covenants as provided in Agreement Section 6 and Agreement Section 10(c). Executive acknowledges that by agreeing to this provision, he knowingly and voluntarily waives any right he may have to a jury trial based on any claims he has, had, or may have against the Company, including any right to a jury trial under any local, municipal, state or federal law including, without limitation, claims under Title VII of the Civil Rights Act of 1964, 42 U.S.C.

c. Non-Disparagement. Executive and the Company agree not to make any statements that disparage the reputation of (i) the Company, its products, services or employees, or (ii) Executive. Executive and the Company further acknowledge and agree that any breach or violation of this non-disparagement provision shall entitle Executive or the Company to seek injunctive relief to prevent any future breaches of this provision and/or to sue the other party on this Agreement for the immediate recovery of any damages caused by such breach. For purposes of this Agreement Section 10(c), the Company’s obligation shall be limited to the Governance and Nominating Committee of TCB’s Board and executives who are members of TCB’s Senior Policy Committee.

d. Limitations on Assignment. In entering into this Agreement, the Company is relying on the unique personal services of Executive; services from another person will not be an acceptable substitute. Except as provided in this Agreement, Executive may not assign this Agreement or any of the rights or obligations set forth in this Agreement without the explicit written consent of the Company. Any attempted assignment by Executive in violation of this Section 10(d) shall be void. Except as provided in this Agreement, nothing in this Agreement entitles any person other than the Parties to the Agreement to any claim, cause of action, remedy, or right of any kind, including, without limitation, the right of continued employment.

e. Severability and Reformation. The Parties intend all provisions of this Agreement to be enforced to the fullest extent permitted by law. If, however, any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future law, such provision shall be fully severable, and this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision were never a part hereof, and the remaining provisions shall remain in

16

full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance. In lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible, and the Company and Executive hereby request the court to whom disputes relating to this Agreement are submitted to reform the otherwise unenforceable covenant in accordance with this Agreement Section 10(e).

f. Notices. Any notice or other communication required, permitted or desired to be given under this Agreement shall be deemed delivered when personally delivered; the next business day, if delivered by overnight courier; the same day, if transmitted by facsimile on a business day before noon, Central Standard Time; the next business day, if otherwise transmitted by facsimile; and the third business day after mailing, if mailed by prepaid certified mail, return receipt requested, as addressed or transmitted as follows (as applicable):

g. Further Acts. Whether or not specifically required under the terms of this Agreement, each party hereto shall execute and deliver such documents and take such further actions as shall be necessary in order for such party to perform all of his or its obligations specified herein or reasonably implied from the Agreement’s terms.

h. Publicity and Advertising. Executive agrees that the Company may use his name, picture, or likeness for any advertising, publicity or other business purpose at any time, during the term of this Agreement and may continue to use materials generated during the term of this Agreement for a period of six months thereafter. Such use of Executive’s name, picture, or likeness shall not be deemed to result in any invasion of Executive’s privacy or in violation of any property right Executive may have; and Executive shall receive no additional consideration if his name, picture or likeness is so used. Executive further agrees that any negatives, prints or other material for printing or reproduction purposes prepared in connection with the use of his name, picture or likeness by the Company shall be and are the sole property of the Company.

i. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS (RULES) OR CHOICE OF LAWS (RULES) THEREOF.

j. Venue. The exclusive venue for all suits or proceedings arising from or related to this Agreement shall be in a court of competent jurisdiction in Dallas County, Texas.

17

k. Entire Agreement and Amendments. This Agreement constitutes the entire agreement between the Parties concerning the subject matter in this Agreement and supersedes any prior agreements between Executive and the Company concerning the subject matter of this Agreement, including, without limitation, the Prior Agreement; provided, however, that nothing herein shall affect the rights of Executive and the Company under that certain Indemnification Agreement dated July 1, 2014, any existing confidentiality or non-disclosure agreement, or any outstanding option, restricted stock unit or stock appreciation rights award relating to the Company’s common stock and previously granted to Executive, or any rights that Executive has under the Company’s benefit plans and fringe benefit policies with respect to service with the Company prior to the Effective Date. No oral statements or prior written material not specifically incorporated in this Agreement shall be of any force and effect, and no changes in or additions to this Agreement shall be recognized, unless incorporated in this Agreement by written amendment, such amendment to become effective on the date stipulated in it. Executive acknowledges and represents that in executing this Agreement, he did not rely, and has not relied, on any communications, promises, statements, inducements, or representation(s), oral or written, by the Company, except as expressly contained in this Agreement. Any amendment to this Agreement must be signed by all Parties to this Agreement. This Agreement will be binding on and inure to the benefit of the Parties hereto and their respective successors, heirs, legal representatives, and permitted assigns (if any).

l. Counterparts. This Agreement may be executed in counterparts, with the same effect as if both Parties had signed the same document. All such counterparts shall be deemed an original, shall be construed together and shall constitute one and the same instrument.

11. Section 409A of the Code.

a. To the extent (i) any payments to which Executive becomes entitled under this Agreement, or any agreement or plan referenced herein, in connection with Executive’s termination of employment with the Company constitute deferred compensation subject to Section 409A of the Code; (ii) Executive is deemed at the time of his separation from service to be a “specified employee” under Section 409A of the Code; and (iii) at the time of Executive’s separation from service the Company is publicly traded (as defined in Section 409A of Code), then such payments (other than any payments permitted by Section 409A of the Code to be paid within six (6) months of Executive’s separation from service) shall not be made until the earlier of (x) the first day of the seventh month following Executive’s separation from service or (y) the date of Executive’s death following such separation from service. During any period that payment or payments to Executive are deferred pursuant to the foregoing, Executive shall be entitled to interest on the deferred payment or payments at a per annum rate equal to Federal-Funds rate as published in The Wall Street Journal on the date of Executive’s termination of employment with the Company. Upon the expiration of the applicable deferral period, any payments which would have otherwise been made during that period (whether in a single sum or in installments) in the absence of this Agreement Section 11 (together with accrued interest thereon) shall be paid to Executive or Executive’s beneficiary in one lump sum.

b. A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” (within the meaning of Section 409A of the Code).

18

c. For purposes of Section 409A of the Code, each payment under Agreement Sections 8 and 9 (and each other severance plan payment) will be treated as a separate payment.

d. It is intended that this Agreement comply with the provisions of Section 409A of the Code and the regulations and guidance of general applicability issued thereunder so as to not subject Executive to the payment of additional interest and taxes under Section 409A of the Code, and in furtherance of this intent, this Agreement shall be interpreted, operated and administered in a manner consistent with these intentions.
