The capitalized terms used herein that are defined in the Plan shall have the same meanings assigned to them in the Plan, except as otherwise expressly provided herein. This Agreement is subject to any rules promulgated pursuant to the Plan by the Board or the Committee and communicated to the Participant in writing.

3.Vesting; Forfeiture. Awarded Units which have become vested pursuant to the terms of this Section 3 are collectively referred to herein as “Vested Units.” All other Awarded Units are collectively referred to herein as “Unvested Units.” The Participant shall be eligible to receive shares of Common Stock with respect to the Vested Units in accordance with Section 4 below. Subject to the provisions of Section 5 and Section 34 below and except as otherwise provided in this Section 3, the Awarded Units will be vested in accordance with the Schedule set forth below, if, as of the date(s) specified in the Schedule, the Participant is employed by (or if the Participant is a Contractor, is providing services to) the Company or its Subsidiaries on such date(s)):

a.Except as otherwise provided by Section 3.b., Section 3.c. and Section 3.d. hereof, immediately upon the Participant’s Termination of Service for any reason whatsoever, the Participant shall be deemed to have forfeited all of the Participant’s Unvested Units. Similarly, if the Participant provides notice to the Company in accordance with Section 7 hereof that he or she is resigning from employment with the Company for any reason, then the Participant shall be deemed to have forfeited all of the Participant’s Unvested Units as of the first day of the Notice Period (as defined in Section 7 hereof).

b.Notwithstanding the foregoing and except as otherwise provided in Section 5 below, in the event that a Change in Control occurs, the acquiror or surviving or resulting corporation assumes the Units and on or after the date of the Change in Control, the Participant incurs a Termination of Service by the Company (or by its successor following the Change in Control) without Cause or by the Participant for Good Reason, then all Unvested Units shall immediately become Vested Units upon such termination.

c.Notwithstanding the foregoing, if the Participant’s employment with the Company or any of its Subsidiaries terminates by reason of the Participant’s death or Total and Permanent Disability, all Unvested Units shall immediately become Vested Units upon such termination.

d.Notwithstanding anything to the contrary contained herein and subject to Section 5 and the Non-Compete in this Section 3.d.(i), if at any time after the date the Participant reaches eligible age for retirement (“Retiring Participant”), the Retiring Participant, after providing the Company with three months written notice of his or her intent to retire, incurs a Termination of Service with the Board’s consent (other than a Termination of Service for Cause or without Good Reason), then, provided that the Company determines that the Retiring Participant continued to perform his or her duties during the three month notice period in accordance with the terms and conditions of the retirement transition plan provided to the Retiring Participant by the Company on or after the date the Retiring Participant provided notice of his or her intent to retire, the Unvested Units shall not be forfeited upon the Participant’s Termination of Service and instead, such Unvested Units shall continue to be subject to the vesting provisions set forth in Section 3.a. as if the Retiring Participant had remained employed by the Company (with shares of Common Stock being delivered pursuant to Section 4 on the original Vesting Dates). The Retiring Participant acknowledges and agrees that once the Retiring Participant provides written notice to the Company of his or her intent to retire, the Retiring Participant shall no longer be eligible to receive any additional grants under the Plan. Eligible age for retirement shall be based on the Retiring Participant’s age plus years of service, in accordance with the Company’s Retirement Policy in effect on the date the Retiring Participant provides written notice of his or her intent to retire.

By execution of this Agreement (whether by electronic means or handwritten signature), the Participant (or Retiring Participant as applicable) agrees to the following:

(i)Confidential Information.

(1)Definition of Confidential Information. The Participant acknowledges that the Company would not provide the Participant with access to its Confidential Information or grant the Awarded Units but for the Participant’s covenants or promises contained in this Section 5.b. For purposes of this Agreement, “Confidential Information” shall mean the Company’s (for purposes of this Section 5.b., the “Company” shall include both the Company and Texas Capital Bank’s (“TCB”)) 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, computer tapes and disks concerning its operations systems, customer lists, customer leads, customer loan and financial information, documents identifying past, present and future customers, customer profiles and preference data, hiring and training methods, investment policies, financial and other confidential, proprietary and/or trade secret information concerning the Company’s operations and expansion plans. Confidential Information includes, without limitation, information about the Company’s business, proprietary, and technical information that is not known to others and could have economic value to others if improperly disclosed. Confidential Information also means any information the Company discloses to the Participant, 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. Confidential Information does not include any information that has become generally available to the public by the act of one who has the right to disclose such information without violating any right or privilege of the Company. The Participant’s obligations under this Section 5 regarding specific Confidential Information shall cease when that specific portion of the Confidential Information loses its status as Confidential Information.

(2)Access to and Agreement Not To Disclose Confidential Information. During the Participant’s employment with Company, the Company agrees to provide the Participant with some or all of the Company’s Confidential Information to which the Participant has not had previous access or knowledge. By executing this Agreement, the Participant agrees that the Confidential Information constitutes valuable, special and unique assets of the Company, developed at the Company’s great expense, the unauthorized use or disclosure of which would cause irreparable harm to the Company. The Participant understands and acknowledges that the Company is engaged in a 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 its competitors. The Participant understands and acknowledges, therefore, that the protection of the Company’s Confidential Information constitutes a legitimate business interest of the Company. The Participant acknowledges that the Confidential Information is the Company’s exclusive property, and the Participant will hold the Confidential

Information in trust and solely for the Company’s benefit. The Participant further acknowledges that portions of the Confidential Information constitute “trade secrets” under Texas and federal law and, in addition to the other protections provided in this Agreement, all trade secrets will be accorded the protection and benefits under Texas law, federal law, and any other applicable law.

In exchange for the Company’s promise to provide the Participant with some or all of the Company’s Confidential Information to which the Participant has not previously had access or knowledge, the Participant agrees that he or she will not, either during the period of the Participant’s employment with the Company or at any time thereafter, use or rely upon for the Participant’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 the Participant alone or in conjunction with others), except (A) as properly required in the ordinary course of the Company’s business or as the Company directs and authorizes or; (B) as required by applicable law (if, to the extent reasonable and practicable, reasonable prior notice of such disclosure is given to the Company). The Participant agrees that he or she will take all reasonable measures to protect the secrecy of and avoid unauthorized disclosure and unauthorized use of the Confidential Information. The Participant also agrees to notify the Company immediately in the event of any unauthorized use, reliance upon or disclosure of the Company’s Confidential Information of which the Participant is aware.

(3)Use of Confidential Information During Employment. The Participant further agrees that in the course of his or her employment by the Company, the Participant will not remove from any office of the Company 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, except as may be required in the performance of the Participant’s duties as an employee of the Company. The Participant also agrees that he or she will not place or save any Confidential Information on any computer or electronic storage system that is not the Company’s property. All Confidential Information, and all memoranda, notes, records, drawings, documents, or other writings whatsoever made, compiled, acquired, or received by the Participant at any time during his or her employment, including during the term of this Agreement, arising out of, in connection with, or related to any activity or business of the Company, 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.

(ii)No Solicitation of Employees/Customers. The Participant agrees that during the Restricted Period, the Participant will not, alone or in combination with any individual, partner(s), 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, recruit, solicit, request, induce or attempt to influence, directly or indirectly, any employee of the Company to resign or terminate employment with the Company. The Participant agrees that during the Restricted Period, he or she 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 or she has done business or with whom he or she has had contact during the last 12 months of the Participant’s employment with the Company.

(1)For purposes of this Agreement, (V) “Restricted Period” means during the Participant’s employment with the Company, and a period equal to the longer of (i) the one year period after the date the Participant’s employment with the Company terminates for any reason, or (ii) as set forth in Section 3.d.(i), in the event the Awarded Units vest in accordance with Section 3.d. above, the remaining vesting period; provided, however, that the Restricted Period for a Participant on Garden Leave in accordance with Section 7, shall commence on the first day of the Garden Leave and continue for a period of twelve (12) months from that date.

(iii)Return of Materials. The Participant agrees that he or she will not retain or destroy (except as set forth below), and will immediately return to the Company on or prior to the Participant’s termination date, or at any other time the Company requests such return, any and all property of the Company that is in the Participant’s possession or subject to his or her control, including, but not limited to, customer files and information, papers, drawings, notes, manuals, specifications, designs, devices, code, email, documents, diskettes, CDs, tapes, keys, access cards, credit cards, identification cards, equipment, computers, mobile devices, other electronic media, all other files and documents relating to the Company and its business (regardless of form, but specifically including all electronic files and data of the Company), together with all Confidential Information belonging to the Company or that the Participant received from or through his or her employment with the Company. The Participant will not make, distribute, or retain copies of any such information or property. To the extent that the Participant has electronic files or information in his possession or control that belong to the Company or otherwise 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 Participant’s termination date, or at any other time the Company requests, the Participant shall (1) provide the Company with an electronic copy of all of such files or information (in an electronic format that readily accessible by the Company); (2) after doing so, delete all such files and information, including all copies and derivatives thereof, from all non-Company-owned computers, mobile devices, electronic media, cloud storage, and other media, devices, and equipment, such that such files and information are permanently deleted and irretrievable; and (3) provide a written certification to the Company that the required deletions have been completed and specifying the files and information deleted and the media source from which they were deleted.

(iv)Reasonableness; Notification. The Participant acknowledges that the geographic boundaries, scope of prohibited activities and the duration of the provisions in Section 3.d.(i) and this Section 5.b are reasonable and are no broader than are necessary to protect the Company’s legitimate business interests. The provisions of Section 3.d.(i) and this Section 5.b shall survive the termination of the Participant’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. The Participant acknowledges that the Company would not provide him or her with access to its Confidential Information but for his or her covenants or promises contained in this Section 5.b. The Participant further agrees that during the Restricted Period, he or she shall immediately notify the Company in writing of any employment, work, or business he or she undertakes with or on behalf of any person (including himself or herself) or entity.

(v)Injunctive Relief. The Participant acknowledges and agrees that the Participant’s obligations, covenants, and agreements in Sections 3.d.(i) and 5.b.(i)-(iii) concern special, unique and extraordinary matters and that a violation of any of the terms of these agreements, covenants or obligations will cause the Company irreparable injury for which adequate remedies at law are not available. Therefore, the Participant agrees that the Company, in addition to any amounts that the Company is entitled to pursuant to Section 5.a. above, will be entitled to an injunction, restraining order, or all other equitable relief as a court or arbitrator of competent jurisdiction may deem necessary or appropriate to restrain the Participant from committing any violation of the agreements, covenants or obligations referred to in Sections 3.d.(i) and 5.b.(i)-(iii). The Participant waives any requirement that the Company post a bond or other security should the need arise.

(vi)Attorneys’ Fees. If the parties become involved in legal action regarding the enforcement of the Protective Covenants, the prevailing party in such action will be entitled, in addition to any other remedy, to recover from the non-prevailing party its/his/her reasonable costs and attorneys’ fees incurred in connection with such action.

(vii)Disclosures to Courts, Governmental Agencies or Administrative or Legislative Bodies. Notwithstanding the foregoing or any other agreement regarding confidentiality with the Company, the Participant may disclose Confidential Information when required to do so by a court of competent jurisdiction, by any governmental agency having authority over the Participant or the business of the Company or by any administrative body or legislative body (including a committee thereof) with jurisdiction to order the Participant to divulge, disclose or make accessible such information. Nothing in this Agreement is intended to interfere with the Participant’s right to (1) report possible violations of state or federal law or regulation to any governmental agency or entity, (2) make other disclosures that are protected under the whistleblower provisions of state or federal law or regulation, (3) file a claim or charge with any government agency or entity, or (4) testify, assist, or participate in an investigation, hearing, or proceeding conducted by any government or law enforcement agency, entity or court.

(viii)Defend Trade Secrets Act of 2016. The Participant is hereby notified in accordance with the Defend Trade Secrets Act of 2016 that the Participant will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (1) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (2) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. The Participant is further notified that if the Participant files a lawsuit for retaliation against the Company for reporting a suspected violation of law, the Participant may disclose the Company’s trade secrets to the Participant’s attorney and use the trade secret information in the court proceeding if the Participant: (x) files any document containing the trade secret under seal; and (y) does not disclose the trade secret, except pursuant to court order.

6.Non-Disparagement. The Participant agrees that during the Restricted Period, the Participant shall not make, publish or communicate to any person or entity or in any public forum (including social media) any defamatory or disparaging remarks, comments or statements concerning the Company or any of its products, services, affiliates, directors, officers, or employees.  Notwithstanding the foregoing, this provision does not in any way limit, restrict, or impede any of the Participant’s rights that are expressly reserved in Section 5(vii) and (vii), or in any way limit the Participant’s ability to provide truthful testimony or information in response to a subpoena, court or arbitral order, or valid request by a government entity, or as otherwise required by law.

19.Law Governing; Forum.

In the event that any one or more of the terms, provisions, or agreements that are contained in this Agreement shall be held by a court or arbitrator of competent jurisdiction to be invalid, illegal, or unenforceable in any respect for any reason, the invalid, illegal, or unenforceable term, provision, or agreement shall not affect any other term, provision, or agreement that is contained in this Agreement. If any of the provisions of Section 5.b should ever be held by a court or arbitrator of competent jurisdiction to exceed the scope permitted by the applicable law, such provision or provisions shall be automatically modified to such lesser scope as such court or arbitrator may deem just and proper for the reasonable protection of the Company’s legitimate business interests and may be enforced by the Company to that extent in the manner described above and all other provisions of this Agreement shall be valid and enforceable.

22.Covenants and Agreements as Independent Agreements. Each of the covenants and agreements set forth in this Agreement shall be construed as a covenant and agreement independent of any other provision of this Agreement.

No change or modification of this Agreement shall be valid or binding upon the parties unless the change or modification is in writing and signed by the parties (electronically or otherwise); provided, however, that the Company may change or modify this Agreement without the Participant’s consent or signature if the Company determines, in its sole discretion, that such change or modification is necessary for purposes of compliance with or exemption from the requirements of Section 409A of the Code or any regulations or other guidance issued thereunder.

27.Headings. The headings that are used in this Agreement are used for reference and convenience purposes only and do not constitute substantive matters to be considered in construing the terms and provisions of this Agreement.

29.Notice. Any notice required or permitted to be delivered hereunder shall be deemed to be delivered only when actually received by the Company or by the Participant, as the case may be, at the addresses set forth below, or at such other addresses as they have theretofore specified by written notice delivered in accordance herewith:

a.Notice to the Company shall be addressed and delivered as follows:

Texas Capital Bancshares, Inc.

2000 McKinney Avenue, Suite 700

Dallas, Texas 75201

Attn: Human Resources

Email: HR@texascapitalbank.com

b.Notice to the Participant shall be addressed and delivered to the most recent address in the Company’s records.

30.Recoupment. The Participant acknowledges, understands and agrees, with respect to any shares of Common Stock delivered to the Participant (or registered in the Participant’s name) pursuant to this Agreement, that such shares of Common Stock shall be subject to recovery by the Company, and the Participant shall be required to repay such compensation or shares of Common Stock, in accordance with the Company’s Recoupment Policy, as in effect from time to time. The Participant further acknowledges, understands, and agrees that the Board retains the right to modify the Company’s Recoupment Policy at any time.

a.The parties agree that to the fullest extent permitted by applicable law any controversy or claim of any party arising out of or in any way relating to this Agreement, the breach thereof, the Participant’s employment with the Company or the termination thereof shall be settled by final, and binding arbitration in Dallas, Texas, in accordance with any Dispute Resolution and Arbitration Agreement (“DRAA”) between the parties or if there is not a DRAA between the parties in accordance with the Arbitration Agreement below; provided, however, that nothing herein shall preclude the Company or the Participant from seeking temporary or preliminary injunctive relief in connection with an arbitrable controversy, including without limitation any controversy under this Agreement. The court to which the application is made is authorized to grant temporary or preliminary injunctive relief and may do so with or without addressing the merits of the underlying arbitrable dispute, as provided by applicable law.  However, all determinations of final relief will be decided in arbitration, and the pursuit of temporary or preliminary injunctive relief shall not be deemed incompatible with or constitute a waiver of rights under the Arbitration Agreement.      

“ARBITRATION AGREEMENT”: IF THE PARTIES ARE NOT SUBJECT TO A DRAA, PARTICIPANT AND THE COMPANY AGREE THAT EXCEPT AS OTHERWISE PROVIDED IN THIS ARBITRATION AGREEMENT, ANY AND ALL CLAIMS OR DISPUTES, PAST, PRESENT, AND FUTURE, ARISING OUT OF OR RELATED TO: (i) THIS AGREEMENT, (ii) ANY OTHER AGREEMENT BETWEEN THEM, OR (iii) PARTICIPANT’S EMPLOYMENT AND SEPARATION OF EMPLOYMENT WITH THE COMPANY, WILL BE DECIDED BY A SINGLE ARBITRATOR THROUGH FINAL AND BINDING ARBITRATION AND NOT BY A JUDGE OR JURY under the then-current Employment Arbitration Rules of the AAA for individually negotiated agreements (“AAA Rules”); provided however, that if there is a conflict between the AAA Rules and this Agreement, this Agreement shall govern.  The AAA Rules may be found at www.adr.org/employment or by searching for “AAA Employment Arbitration Rules” using a service such as www.Google.com. The provisions set forth herein, including all waivers included herein, shall be governed by and

interpreted in accordance with the Federal Arbitration Act. If a court determines the FAA does not apply to a particular dispute or to one or both parties, the parties agree that the Texas Arbitration Act (“TAA”) will apply and acknowledge that the Company is based in Texas. If neither the FAA or TAA apply, the parties stipulate and agree the arbitration law of the jurisdiction where the arbitration will take place will apply. The Company and Participant waive any right for any dispute to be brought, heard, decided, or arbitrated as a class action or collective action, and the arbitrator will have no authority to preside over any class or collective action (“Class Action Waiver”). The following claims and disputes are not covered under this Arbitration Agreement: (i) Workers’ Compensation benefit claims (but workers’ compensation discrimination or retaliation is covered); (ii) state unemployment or disability insurance compensation claims; and (iii) disputes that may not be arbitrated or subject to pre-dispute arbitration as expressly provided by Dodd-Frank Wall Street Reform and Consumer Protection Act or other controlling federal statute.”

b.FINRA Registered Representatives or Associated Persons. This Section applies to Registered Representatives or Associated Persons, as classified pursuant to the Financial Industry Regulatory Authority (FINRA). To the maximum extent allowed by law, Registered Representatives or Associated Persons, as classified by FINRA, and the Company waive FINRA Rule 13200 (or any successor rule) and agree that any dispute arising out of or related to Your application and selection for employment, employment, and/or termination of employment shall be arbitrated pursuant to this Agreement—and not in a FINRA arbitral forum. 

c.FINRA Exception. If the above waiver of FINRA 13200 is deemed invalid or unenforceable, arbitration between the Company and Registered Representatives or Associated Persons, as classified pursuant to FINRA, will be administered by FINRA in individual, bilateral arbitration in accordance with its Code of Arbitration Procedure for Industry Disputes and the FINRA Rules; provided, however, Participant and the Company waive any right to commence, be a party to or an actual or putative class member of any class or collective action arising out of or relating to Participant’s employment with the Company, and agree that any dispute must be arbitrated on an individual, bilateral basis. Additionally, if (1) FINRA declines to hear an arbitration of a dispute between the Company and a Registered Representative or Associated Person, and/or (2) if a claim or dispute is deemed not arbitrable under the FINRA Rules or Code of Arbitration Procedure for Industry Disputes, such disputes shall be resolved in individual arbitration in accordance with this Agreement—including without limitation, the Class and Collective Action Waivers section. 

32.Waiver of Jury Trial. BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON, THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY AN ARBITRATOR OR, AS PERMITTED BY SECTION 31 ABOVE, A JUDGE HEARING A PETITION FOR PRELIMINARY INJUNCTIVE RELIEF. THEREFORE, EACH PARTY TO THIS AGREEMENT HEREBY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE BETWEEN OR AMONG ANY OF THE PARTIES HERETO, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE, ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY, AND/OR THE RELATIONSHIP ESTABLISHED AMONG THE PARTIES HEREUNDER.

33.Tax Requirements. The Participant is hereby advised to consult immediately with his or her own tax advisor regarding the tax consequences of this Agreement, including, without limitation, any possible tax consequences of this Agreement in connection with Section 409A of the Code. The Company, or if applicable, any Subsidiary (for purposes of this Section 33, the term “Company” shall be deemed to include any applicable Subsidiary) has the authority and the right to deduct or withhold, or require the Participant to remit to the employer, an amount sufficient to satisfy federal, state, and local taxes (including the Participant’s FICA obligation) required by law to be withheld with respect to any taxable event arising as a result of the vesting or conversion of the RSUs. Unless otherwise determined by the Committee at the time the Award is granted or thereafter, the Company shall satisfy any such

withholding requirement by withholding the number of Awarded Shares having a Fair Market Value on the date of withholding equal to the amount required to be withheld for tax purposes.

34.Section 409A.

a.To the extent (i) any shares of Common Stock to which the Participant becomes entitled under this Agreement, or any agreement or plan referenced herein, in connection with the Participant's Termination of Service with the Company constitutes deferred compensation subject to Section 409A of the Code (“Non-Exempt Deferred Compensation”); (ii) the Participant is deemed at the time of his or her separation from service to be a “specified employee” under Section 409A of the Code; and (iii) at the time of the Participant’s separation from service the Company is publicly traded (as defined in Section 409A of the Code), then such shares of Common Stock (other than any delivery of Common Stock permitted by Section 409A of the Code to be paid or delivered within six months of the Participant’s separation from service) shall not be made until the earlier of (x) the first day of the seventh month following the Participant’s separation from service or (y) the date of the Participant’s death following such separation from service. Upon the expiration of the applicable deferral period, any shares of Common Stock which would have otherwise been made during that period (whether in a single sum or in installments) in the absence of this Section 34 (together with, as applicable, accrued interest thereon) shall be delivered to the Participant or the Participant's beneficiary in one lump sum.

b.To the extent any shares of Common Stock to which the Participant becomes entitled under this Agreement, or any agreement or plan referenced herein, in connection with the Participant's Termination of Service with the Company constitutes Non-Exempt Deferred Compensation, a Termination of Service 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 Service unless such termination is also a “separation from service” (within the meaning of Section 409A of the Code).

c.It is intended that this Agreement comply with the provisions of Section 409A of the Code so as to not subject the Participant 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.
