AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of December 9, 2019 (this “Agreement”), by and between Texas Capital Bancshares, Inc., a Delaware corporation (“TCBI”), and Independent Bank Group, Inc., a Texas corporation (“IBTX”).

W I T N E S S E T H:

WHEREAS, the Boards of Directors of IBTX and TCBI have determined that it is in the best interests of their respective companies and their shareholders to consummate the strategic business combination transaction provided for herein, pursuant to which TCBI will, subject to the terms and conditions set forth herein, merge with and into IBTX (the “Merger”), so that IBTX is the surviving entity (hereinafter sometimes referred to in such capacity as the “Surviving Entity”) in the Merger;

WHEREAS, in furtherance thereof, the respective Boards of Directors of IBTX and TCBI have approved the Merger and this Agreement;

WHEREAS concurrently with the execution and delivery of this Agreement and as a condition to TCBI’s willingness to enter into this Agreement, TCBI and a certain stockholder of IBTX are entering into a voting agreement, pursuant to which, among other things, such stockholder has agreed to vote to approve this Agreement, upon the terms and subject to the conditions set forth therein;

WHEREAS, for federal income tax purposes, it is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement is intended to be and is adopted as a plan of reorganization for purposes of Sections 354 and 361 of the Code; and

WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained herein, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Texas Business Organizations Code (the “TBOC”) and the Delaware General Corporation Law (the “DGCL”), at the Effective Time, TCBI shall merge with and into IBTX pursuant to this Agreement. IBTX shall be the Surviving Entity in the Merger, and shall continue its corporate existence under the laws of the State of Texas. Upon consummation of the Merger, the separate corporate existence of TCBI shall terminate.

-1-

1.2 Closing. Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) will take place by electronic exchange of documents at 10:00 a.m., New York City time, on a date which shall be no later than three (3) business days after the satisfaction or waiver (subject to applicable law) of all the conditions set forth in Article VII hereof (other than those conditions that by their nature can only be satisfied at the Closing, but subject to the satisfaction or waiver thereof), unless another date, time or place is agreed to in writing by TCBI and IBTX. The date on which the Closing occurs is referred to as the “Closing Date.”

1.3 Effective Time. On or (if agreed by TCBI and IBTX) prior to the Closing Date, IBTX and TCBI, respectively, shall cause to be filed a certificate of merger with the Secretary of State of the State of Delaware (the “Delaware Secretary”) and a certificate of merger with the Secretary of State of the State of Texas (the “Texas Secretary”) (collectively, the “Certificates of Merger”). The Merger shall become effective at such time as specified in the Certificates of Merger in accordance with the relevant provisions of the TBOC and DGCL, or at such other time as shall be provided by applicable law (such time hereinafter referred to as the “Effective Time”).

1.4 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the TBOC and the DGCL.

1.5 Conversion of TCBI Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of IBTX, TCBI or the holder of any securities of IBTX or TCBI:

(a) Subject to Section 2.2(e), each share of the common stock, par value $0.01 per share, of TCBI issued and outstanding immediately prior to the Effective Time (the “TCBI Common Stock”), except for shares of TCBI Common Stock owned by TCBI or IBTX (in each case other than shares of TCBI Common Stock (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties or (ii) held, directly or indirectly, by TCBI or IBTX in respect of debts previously contracted), shall be converted into the right to receive 1.0311 shares (the “Exchange Ratio” and such shares the “Merger Consideration”) of the common stock, par value $0.01 per share, of IBTX (the “IBTX Common Stock”); it being understood that upon the Effective Time, pursuant to Section 1.6, the IBTX Common Stock, including the shares issued to former holders of TCBI Common Stock, shall be the common stock of the Surviving Entity.

(b) All the shares of TCBI Common Stock converted into the right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate (each, an “Old Certificate,” it being understood that any reference herein to “Old Certificate” shall be deemed to include reference to book‑entry account statements relating to the ownership of shares of TCBI Common Stock) previously representing any such shares of TCBI Common Stock shall thereafter represent only the right to receive (i) a New Certificate representing the number of whole shares of IBTX Common Stock which such shares of TCBI Common Stock have been converted into the right to receive, (ii) cash in lieu of fractional shares which the shares of TCBI Common Stock represented by such Old Certificate have been converted into the right to receive pursuant to this Section 1.5 and Section 2.2(e), without any interest thereon and (iii) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2, in each case, without any interest thereon. If, prior to the Effective Time, the outstanding shares of IBTX Common Stock or TCBI Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split or reverse stock split, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Exchange Ratio to give IBTX and the holders of TCBI Common Stock the same economic effect as contemplated by this Agreement prior to such event; provided that nothing contained in this sentence shall be construed to permit TCBI or IBTX to take any action with respect to its securities or otherwise that is prohibited by the terms of this Agreement.

-2-

(c) Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all shares of TCBI Common Stock that are owned by TCBI or IBTX (in each case other than shares of TCBI Common Stock (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties or (ii) held, directly or indirectly, by TCBI or IBTX in respect of debts previously contracted) shall be cancelled and shall cease to exist and no IBTX Common Stock or other consideration shall be delivered in exchange therefor.

1.6 IBTX Stock. At and after the Effective Time, each share of IBTX Common Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of the Surviving Entity and shall not be affected by the Merger.

1.7 TCBI Preferred Stock. At the Effective Time, by virtue of the Merger and without any action on the part of IBTX, TCBI or the holder of any securities of IBTX or TCBI, each share of 6.50% Non-Cumulative Perpetual Preferred Stock, Series A, par value $0.01 per share, of TCBI (“TCBI Preferred Stock”) issued and outstanding immediately prior to the Effective Time shall automatically be converted into the right to receive a share of a newly created series of preferred stock of IBTX having substantially the same terms as the TCBI Preferred Stock (taking into account that TCBI will not be the surviving entity in the Merger and any adjustment to the right of optional redemption by IBTX that is reasonably necessary to obtain Tier 1 Capital treatment from the Federal Reserve Board for such preferred stock) (all shares of such newly created series, collectively, the “New IBTX Preferred Stock”) and, upon such conversion, the TCBI Preferred Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time.

1.8 Treatment of TCBI Equity Awards.

(a) At the Effective Time, each stock appreciation right to purchase shares of TCBI Common Stock (a “TCBI SAR”) that is outstanding and unexercised immediately prior to the Effective Time, whether vested or unvested, shall, automatically and without any required action on part of the holder thereof, be cancelled, with the holder of such TCBI SAR becoming entitled to receive, in full satisfaction of the rights of the holder with respect thereto, the Merger Consideration in respect of each Net Share (as defined below) covered by such TCBI SAR, less applicable Tax withholding, which shall be delivered as soon as reasonably practicable following the Closing Date and in no event later than ten (10) business days following the Closing Date. For purposes of this Section 1.8(a):

-3-

(i) “Net Share” means, with respect to a TCBI SAR, the quotient obtained by dividing (A) the product of (i) the excess, if any, of the Per Share Cash Equivalent Consideration over the per share exercise price of such TCBI SAR, multiplied by (ii) the number of shares of TCBI Common Stock subject to such TCBI SAR immediately prior to the Effective Time, by (B) the Per Share Cash Equivalent Consideration.

(ii) “Per Share Cash Equivalent Consideration” means the product (rounded to the nearest cent) obtained by multiplying (A) the Exchange Ratio by (B) the average of the closing-sale prices of IBTX Common Stock on the NASDAQ Stock Market, Inc. Global Select Market System (the “NASDAQ”) as reported by The Wall Street Journal for the consecutive period of five (5) full trading days ending on the day preceding the Closing Date.

(b) Except as otherwise agreed between IBTX and TCBI, at the Effective Time, each award in respect of a share of TCBI Common Stock subject to vesting, repurchase or other lapse restriction granted to a non-employee director of the Board of Directors of TCBI in respect of such service (a “TCBI Restricted Stock Award”) that is outstanding immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder thereof, immediately and fully vest and be converted into the right to receive the Merger Consideration, less applicable Tax withholding, which shall be delivered as soon as reasonably practicable following the Closing Date and in no event later than ten (10) business days following the Closing Date.

(c) Except as otherwise agreed between IBTX and TCBI, at the Effective Time, each restricted stock unit award in respect of shares of TCBI Common Stock (a “TCBI RSU Award”) that is outstanding immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder thereof, immediately and fully vest and be converted into the right to receive the Merger Consideration in respect of the number of shares of TCBI Common Stock subject to such TCBI RSU Award immediately prior to the Effective Time, less applicable Tax withholding, which shall be delivered as soon as reasonably practicable following the Closing Date and in no event later than ten (10) business days following the Closing Date; provided that, any cash-settled TCBI RSU Award shall be converted into the right to receive an amount in cash equal to the Per Share Cash Equivalent Consideration in respect of the number of shares of TCBI Common Stock subject to such TCBI RSU Award immediately prior to the Effective Time, less applicable Tax withholding; provided further, with respect to any TCBI RSU Award that constitutes “deferred compensation” subject to Section 409A of the Code, settlement or payment of such award shall be made on the earliest permissible date that such delivery would not trigger a Tax or penalty under Section 409A of the Code.

-4-

(d) Except as otherwise agreed between IBTX and TCBI, at the Effective Time, each performance unit award in respect of shares of TCBI Common Stock (a “TCBI Performance Unit Award”) that is outstanding immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder thereof, immediately vest (based on the level of achievement of the applicable performance goals set forth below) and be converted into the right to receive the Merger Consideration in respect of the number of shares of TCBI Common Stock subject to such TCBI Performance Unit Award immediately prior to the Effective Time as determined pursuant to the following sentence, less applicable Tax withholding which shall be delivered as soon as reasonably practicable following the Closing Date and in no event later than ten (10) business days following the Closing Date; provided, that any cash-settled TCBI Performance Unit Award shall be converted into the right to receive an amount in cash equal to the Per Share Cash Equivalent Consideration in respect of the number of shares of TCBI Common Stock subject to such TCBI Performance Unit Award immediately prior to the Effective Time (based on the level of achievement of the applicable performance goals set forth below), less applicable Tax withholding; provided further, with respect to any TCBI Performance Unit Award that constitutes “deferred compensation” subject to Section 409A of the Code, settlement of such award shall be made on the earliest permissible date that such delivery would not trigger a Tax or penalty under Section 409A of the Code. For purposes of this Section 1.8(d), the number of shares of TCBI Common Stock subject to TCBI Performance Unit Awards that shall vest and be earned shall be determined based on the greater of (i) the level of actual performance achieved prior to the Effective Time as reasonably determined by the human resources committee of the Board of Directors of TCBI (the “TCBI Compensation Committee”) using the information available through the latest practicable date prior to the Effective Time and otherwise consistent with past practice, and (ii) target level performance.

(e) The TCBI Board of Directors (or appropriate committee thereof) shall take such action as is necessary to ensure that (i) the “offering period” in effect as of the date hereof under the TCBI 2006 Employee Stock Purchase Plan (the “ESPP”) shall be the last purchase period under the ESPP, (ii) no new purchase period shall commence after the date hereof and prior to the Effective Time, (iii) participation in the ESPP shall be limited to those employees who were participants on the date hereof, (iv) current participants may not increase their payroll deduction election or purchase elections from those in effect on the date hereof, and (v) effective as of the Effective Time, the ESPP shall terminate.

(f) Prior to the Effective Time, TCBI, the Board of Directors of TCBI and the TCBI Compensation Committee, as applicable, shall adopt any resolutions and take any actions that are necessary or appropriate to effectuate the provisions of this Section 1.8.

1.9 Certificate of Formation of Surviving Entity. At the Effective Time, the certificate of formation of IBTX, as in effect immediately prior to the Effective Time, as amended as set forth in Exhibit A (the “IBTX Certificate Amendment”), shall be the certificate of formation of the Surviving Entity until thereafter amended in accordance with applicable law.

1.10 Bylaws of Surviving Entity. At the Effective Time, the bylaws of IBTX, as amended as set forth in Exhibit B (such amendment, the “IBTX Bylaw Amendment”), shall be the bylaws of the Surviving Entity until thereafter amended in accordance with applicable law.

-5-

1.11 Tax Consequences. It is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement is intended to be and is adopted as a plan of reorganization for the purposes of Sections 354 and 361 of the Code.

1.12 Bank Merger. Immediately following the Merger, Texas Capital Bank, a federally-chartered national association and wholly-owned Subsidiary of TCBI (“TCBI Subsidiary Bank”), will merge with and into Independent Bank, a Texas-chartered state bank and wholly-owned Subsidiary of IBTX (“IBTX Subsidiary Bank”) (the “Bank Merger”). IBTX Subsidiary Bank shall be the surviving entity in the Bank Merger and, following the Bank Merger, the separate corporate existence of TCBI Subsidiary Bank shall cease. Promptly after the date of this Agreement, IBTX Subsidiary Bank and TCBI Subsidiary Bank will enter into an agreement and plan of merger in form and substance agreed by IBTX and TCBI, which shall be customary for mergers similar to the Bank Merger (the “Bank Merger Agreement”). Each of IBTX and TCBI shall approve the Bank Merger Agreement and the Bank Merger as the sole shareholder of IBTX Subsidiary Bank and TCBI Subsidiary Bank, respectively, and IBTX and TCBI shall, and shall cause IBTX Subsidiary Bank and TCBI Subsidiary Bank, respectively, to, execute certificates or articles of merger and such other documents and certificates as are necessary to make the Bank Merger effective (“Bank Merger Certificates”) immediately following the Effective Time. The Bank Merger shall become effective at such time and date as specified in the Bank Merger Agreement in accordance with applicable law, or at such other time as shall be provided by applicable law.

ARTICLE II

EXCHANGE OF SHARES

2.1 IBTX to Make Consideration Available. At or prior to the Effective Time, IBTX shall deposit, or shall cause to be deposited, with a bank or trust company mutually agreed upon by IBTX and TCBI (the “Exchange Agent”), for exchange in accordance with this Article II for the benefit of the holders of Old Certificates (which for purposes of this Article II shall be deemed to include certificates or book-entry account statements representing shares of TCBI Preferred Stock), certificates or, at IBTX’s option, evidence in book-entry form, representing shares of IBTX Common Stock or New IBTX Preferred Stock to be issued pursuant to Section 1.5 and Section 1.7, respectively (collectively, referred to herein as “New Certificates”), and cash in lieu of any fractional shares to be paid pursuant to Section 2.2(e) (such cash and New Certificates, together with any dividends or distributions with respect to shares of IBTX Common Stock or New IBTX Preferred Stock payable in accordance with Section 2.2(b), being hereinafter referred to as the “Exchange Fund”).

-6-

2.2 Exchange of Shares.

(a) As promptly as practicable after the Effective Time, but in no event later than ten (10) days thereafter, IBTX and TCBI shall cause the Exchange Agent to mail to each holder of record of one or more Old Certificates representing shares of TCBI Common Stock or TCBI Preferred Stock immediately prior to the Effective Time that have been converted at the Effective Time into the right to receive IBTX Common Stock or New IBTX Preferred Stock, as applicable, pursuant to Article I, a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates shall pass, only upon proper delivery of the Old Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates in exchange for New Certificates representing the number of whole shares of IBTX Common Stock and any cash in lieu of fractional shares or shares of New IBTX Preferred Stock, as applicable, which the shares of TCBI Common Stock or TCBI Preferred Stock represented by such Old Certificate or Old Certificates shall have been converted into the right to receive pursuant to this Agreement as well as any dividends or distributions to be paid pursuant to Section 2.2(b). Upon proper surrender of an Old Certificate or Old Certificates for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Old Certificate or Old Certificates shall be entitled to receive in exchange therefor, as applicable, (i) (A) a New Certificate representing that number of whole shares of IBTX Common Stock to which such holder of TCBI Common Stock shall have become entitled pursuant to the provisions of Article I and (B) a check representing the amount of (x) any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II and (y) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b) or (ii) (A) a New Certificate representing that number of shares of New IBTX Preferred Stock to which such holder of TCBI Preferred Stock shall have become entitled pursuant to the provisions of Article I, and (B) a check representing the amount of any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), and the Old Certificate or Old Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any cash in lieu of fractional shares or dividends or distributions payable to holders of Old Certificates. Until surrendered as contemplated by this Section 2.2, each Old Certificate shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the number of whole shares of IBTX Common Stock or shares of New IBTX Preferred Stock which the shares of TCBI Common Stock or TCBI Preferred Stock, as applicable, represented by such Old Certificate have been converted into the right to receive and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.2.

(b) No dividends or other distributions declared with respect to IBTX Common Stock or New IBTX Preferred Stock shall be paid to the holder of any unsurrendered Old Certificate until the holder thereof shall surrender such Old Certificate in accordance with this Article II. After the surrender of an Old Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to the whole shares of IBTX Common Stock or shares of New IBTX Preferred Stock that the shares of TCBI Common Stock or TCBI Preferred Stock, as applicable, represented by such Old Certificate have been converted into the right to receive.

(c) If any New Certificate representing shares of IBTX Common Stock or New IBTX Preferred Stock is to be issued in a name other than that in which the Old Certificate or Old Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificate or Old Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of a New Certificate representing shares of IBTX Common Stock or New IBTX Preferred Stock in any name other than that of the registered holder of the Old Certificate or Old Certificates surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(d) After the Effective Time, there shall be no transfers on the stock transfer books of TCBI of the shares of TCBI Common Stock or TCBI Preferred Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Old Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for New Certificates representing shares of IBTX Common Stock or New IBTX Preferred Stock, as applicable, as provided in this Article II.

(e) Notwithstanding anything to the contrary contained herein, no New Certificates or scrip representing fractional shares of IBTX Common Stock shall be issued upon the surrender for exchange of Old Certificates (or in satisfaction of the obligations set forth in Section 1.8 in respect of TCBI Equity Awards), no dividend or distribution with respect to IBTX Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of IBTX. In lieu of the issuance of any such fractional share, IBTX shall pay to each former holder of TCBI Common Stock or any TCBI Equity Awards who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing-sale prices of IBTX Common Stock on the NASDAQ as reported by The Wall Street Journal for the consecutive period of five (5) full trading days ending on the day preceding the Closing Date by (ii) the fraction of a share (after taking into account all shares of TCBI Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest one-thousandth when expressed in decimal form) of IBTX Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.5 or Section 1.8. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares.

(f) Any portion of the Exchange Fund that remains unclaimed by the shareholders of TCBI for twelve (12) months after the Effective Time shall be paid to the Surviving Entity. Any former holders of TCBI Common Stock or TCBI Preferred Stock who have not theretofore complied with this Article II shall thereafter look only to the Surviving Entity for payment of the shares of IBTX Common Stock, cash in lieu of any fractional shares and any unpaid dividends and distributions on the IBTX Common Stock deliverable in respect of each former share of TCBI Common Stock such holder holds as determined pursuant to this Agreement, or the shares of New IBTX Preferred Stock and any unpaid dividends and distributions on the New IBTX Preferred Stock deliverable in respect of each former share of TCBI Preferred Stock such holder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of IBTX, TCBI, the Surviving Entity, the Exchange Agent or any other person shall be liable to any former holder of shares of TCBI Common Stock or TCBI Preferred Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

-8-

(g) IBTX shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from any cash in lieu of fractional shares of IBTX Common Stock, cash dividends or distributions payable pursuant to this Section 2.2 or any other amounts otherwise payable pursuant to this Agreement to any holder of TCBI Common Stock, TCBI Preferred Stock or TCBI Equity Awards, such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by IBTX or the Exchange Agent, as the case may be, and paid over to the appropriate governmental authority, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of TCBI Common Stock, TCBI Preferred Stock or TCBI Equity Awards in respect of which the deduction and withholding was made by IBTX or the Exchange Agent, as the case may be.

(h) In the event any Old Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Old Certificate to be lost, stolen or destroyed and, if required by IBTX or the Exchange Agent, the posting by such person of a bond in such amount as IBTX or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the shares of IBTX Common Stock and any cash in lieu of fractional shares, or the shares of New IBTX Preferred Stock, as applicable, deliverable in respect thereof pursuant to this Agreement.

3.1 Corporate Organization.

(a) TCBI is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware, is a bank holding company duly registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”) and has elected to be treated as a financial holding company under the BHC Act. TCBI has the corporate power and authority to own, lease or operate all of its properties and assets and to carry on its business as it is now being conducted. TCBI is duly licensed or qualified to do business and in good standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned, leased or operated by it makes such licensing, qualification or standing necessary, except where the failure to be so licensed or qualified or to be in good standing would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on TCBI. As used in this Agreement, the term “Material Adverse Effect” means, with respect to IBTX, TCBI or the Surviving Entity, as the case may be, any effect, change, event, circumstance, condition, occurrence or development that, either individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (i) the business, properties, assets, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in U.S. generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements, (B) changes, after the date hereof, in laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate, or interpretations thereof by courts or Governmental Entities, (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally and not specifically relating to such party or its Subsidiaries, (D) public disclosure of the transactions contemplated hereby or actions expressly required by this Agreement or that are taken with the prior written consent of the other party in contemplation of the transactions contemplated hereby, or (E) a decline in the trading price of a party’s common stock or the failure, in and of itself, to meet earnings projections or internal financial forecasts, but not, in either case, including any underlying causes thereof; except, with respect to subclause (A), (B), or (C), to the extent that the effects of such change are materially disproportionately adverse to the business, properties, assets, results of operations or financial condition of such party and its Subsidiaries, taken as a whole, as compared to other companies in the industry in which such party and its Subsidiaries operate) or (ii) the ability of such party to timely consummate the transactions contemplated hereby. As used in this Agreement, the word “Subsidiary” when used with respect to any person, means any corporation, partnership, limited liability company, bank or other organization, whether incorporated or unincorporated, or person of which (x) such first person directly or indirectly owns or controls at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the board of directors or others performing similar functions or (y) such first person is or directly or indirectly has the power to appoint a general partner, manager or managing member or others performing similar functions. True and complete copies of the certificate of incorporation of TCBI, as amended (the “TCBI Certificate of Incorporation”) and the amended and restated bylaws of TCBI, as amended (the “TCBI Bylaws”), in each case as in effect as of the date of this Agreement, have previously been made available by TCBI to IBTX.

-10-

(b) Except as would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on TCBI, each Subsidiary of TCBI (a “TCBI Subsidiary”) (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly licensed or qualified to do business and, where such concept is recognized under applicable law, in good standing in all jurisdictions (whether federal, state, local or foreign) where its ownership, leasing or operation of property or the conduct of its business requires it to be so licensed or qualified or in good standing and (iii) has all requisite corporate power and authority to own, lease or operate its properties and assets and to carry on its business as now conducted. There are no restrictions on the ability of TCBI or any Subsidiary of TCBI to pay dividends or distributions except, in the case of TCBI or a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all similarly regulated entities. The deposit accounts of each Subsidiary of TCBI that is an insured depository institution are insured by the Federal Deposit Insurance Corporation (the “FDIC”) through the Deposit Insurance Fund (as defined in Section 3(y) of the Federal Deposit Insurance Act of 1950) to the fullest extent permitted by law, all premiums and assessments required to be paid in connection therewith have been paid when due, and no proceedings for the termination of such insurance are pending or threatened. Section 3.1(b) of the TCBI Disclosure Schedule sets forth a true and complete list of all Subsidiaries of TCBI that would constitute “significant subsidiaries” within the meaning of Rule 1-02 of Regulation S-X of the SEC as of the date hereof. There is no person whose results of operations, cash flows, changes in shareholders’ equity or financial position are consolidated in the financial statements of TCBI other than the TCBI Subsidiaries.

TCBI is current on all dividends payable on the outstanding shares of TCBI Preferred Stock, and has complied in all material respects with terms and conditions thereof.

Other than TCBI Equity Awards, no equity-based awards (including any cash awards where the amount of payment is determined, in whole or in part, based on the price of any capital stock of TCBI or any of its Subsidiaries) are outstanding. There are no voting trusts, shareholder agreements, proxies or other agreements in effect to which TCBI or any of its Subsidiaries is a party with respect to the voting or transfer of TCBI Common Stock, capital stock or other voting or equity securities or ownership interests of TCBI or granting any shareholder or other person any registration rights.

Except for the approval of this Agreement by the affirmative vote of a majority of the outstanding shares of TCBI Common Stock entitled to vote on this Agreement (the “Requisite TCBI Vote”), and the approval of the Bank Merger Agreement by TCBI as TCBI Subsidiary Bank’s sole shareholder, no other corporate proceedings on the part of TCBI are necessary to approve this Agreement or to consummate the transactions contemplated hereby. This Agreement has been duly and validly executed and delivered by TCBI and (assuming due authorization, execution and delivery by IBTX) constitutes a valid and binding obligation of TCBI, enforceable against TCBI in accordance with its terms (except in all cases as such enforceability may be limited by bankruptcy, insolvency, moratorium, reorganization or similar laws of general applicability affecting the rights of creditors generally and the availability of equitable remedies (the “Enforceability Exceptions”)).

Subject to Section 9.14, there (i) is no unresolved violation, criticism, or exception by any Regulatory Agency with respect to any report or statement relating to any examinations or inspections of TCBI or any of its Subsidiaries and (ii) has been no formal or informal inquiries by, or disagreements or disputes with, any Regulatory Agency with respect to the business, operations, policies or procedures of TCBI or any of its Subsidiaries since January 1, 2017, in each case, which would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on TCBI.

3.6 Financial Statements.

Since December 31, 2016, no independent public accounting firm of TCBI has resigned (or informed TCBI that it intends to resign) or been dismissed as independent public accountants of TCBI as a result of or in connection with any disagreements with TCBI on a matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

-14-

(b) Except as would not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on TCBI, neither TCBI nor any of its Subsidiaries has any liability of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether due or to become due), except for those liabilities that are reflected or reserved against on the consolidated balance sheet of TCBI included in its Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2019 (including any notes thereto) and for liabilities incurred in the ordinary course of business consistent with past practice since September 30, 2019, or in connection with this Agreement and the transactions contemplated hereby.

(c) The records, systems, controls, data and information of TCBI and its Subsidiaries are recorded, stored, maintained and operated under means (including any electronic, mechanical or photographic process, whether computerized or not) that are under the exclusive ownership of TCBI or its Subsidiaries or accountants (including all means of access thereto and therefrom), except for any non-exclusive ownership that would not reasonably be expected to have a Material Adverse Effect on TCBI. TCBI (x) has implemented and maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) to ensure that material information relating to TCBI, including its Subsidiaries, is made known to the chief executive officer and the chief financial officer of TCBI by others within those entities as appropriate to allow timely decisions regarding required disclosures and to make the certifications required by the Exchange Act and Sections 302 and 906 of the Xxxxxxxx-Xxxxx Act of 2002 (the “Xxxxxxxx-Xxxxx Act”), and (y) has disclosed, based on its most recent evaluation prior to the date hereof, to TCBI’s outside auditors and the audit committee of TCBI’s Board of Directors (i) any significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) which are reasonably likely to adversely affect TCBI’s ability to record, process, summarize and report financial information, and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in TCBI’s internal controls over financial reporting. These disclosures were made in writing by management to TCBI’s auditors and audit committee and true, correct and complete copies of such disclosures have been made available by TCBI to IBTX. There is no reason to believe that TCBI’s outside auditors and its chief executive officer and chief financial officer will not be able to give the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the Xxxxxxxx-Xxxxx Act, without qualification, when next due.

-15-

LLC related to the Merger and the other transactions contemplated hereunder.

Neither TCBI nor any of its Subsidiaries is the beneficiary of any extension of time within which to file any material Tax Return (other than extensions to file Tax Returns obtained in the ordinary course). All material Taxes of TCBI and its Subsidiaries (whether or not shown on any Tax Returns) that are due have been fully and timely paid. Each of TCBI and its Subsidiaries has withheld and paid all material Taxes required to have been withheld and paid in connection with amounts paid or owing to any employee, creditor, shareholder, independent contractor or other third party. Neither TCBI nor any of its Subsidiaries has granted any extension or waiver of the limitation period applicable to any material Tax that remains in effect (other than extension or waiver granted in the ordinary course of business). Neither TCBI nor any of its Subsidiaries has received written notice of assessment or proposed assessment in connection with any material amount of Taxes, and there are no threatened in writing or pending disputes, claims, audits, examinations or other proceedings regarding any material Tax of TCBI and its Subsidiaries or the assets of TCBI and its Subsidiaries. Neither TCBI nor any of its Subsidiaries is a party to or is bound by any Tax sharing, allocation or indemnification agreement or arrangement (other than such an agreement or arrangement exclusively between or among TCBI and its Subsidiaries). Since January 1, 2013, neither TCBI nor any of its Subsidiaries (A) has been a member of an affiliated group filing a consolidated federal income Tax Return for which the statute of limitations is open (other than a group the common parent of which was TCBI) or (B) has any liability for the Taxes of any person (other than TCBI or any of its Subsidiaries) under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local or foreign law), as a transferee or successor, by contract or otherwise (other than pursuant to agreements not primarily related to Taxes and entered into in the ordinary course of business consistent with past practice). Neither TCBI nor any of its Subsidiaries has been, within the past two (2) years or otherwise as part of a “plan (or series of related transactions)” within the meaning of Section 355(e) of the Code of which the Merger is also a part, a “distributing corporation” or a “controlled corporation” (within the meaning of Section 355(a)(1)(A) of the Code) in a distribution of stock intending to qualify for tax-free treatment under Section 355 of the Code.

IBTX and TCBI shall have the right to review in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to TCBI or IBTX, as the case may be, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity, including the Joint Proxy Statement, the S-4 and any other filing made in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto shall act reasonably and as promptly as practicable. The parties hereto agree that they will consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations of all third parties and Governmental Entities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other apprised of the status of matters relating to completion of the transactions contemplated herein, and each party shall consult with the other in advance of any meeting or conference with any Governmental Entity in connection with the transactions contemplated by this Agreement and, to the extent permitted by such Governmental Entity, give the other party and/or its counsel the opportunity to attend and participate in such meetings and conferences, in each case subject to applicable law.

-52-

(d) IBTX and TCBI shall, upon request, furnish each other with all information concerning themselves, their Subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with the Joint Proxy Statement, the S-4 or any other statement, filing, notice or application made by or on behalf of IBTX, TCBI or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement.

(e) IBTX and TCBI shall promptly advise each other upon receiving any communication from any Governmental Entity whose consent or approval is required for consummation of the transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained, or that the receipt of any such approval will be materially delayed.

6.2 Access to Information; Confidentiality.

(a) Subject to Section 9.14, upon reasonable notice and subject to applicable laws, each of IBTX and TCBI, for the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, shall, and shall cause each of their respective Subsidiaries to, afford to the officers, employees, accountants, counsel, advisors and other representatives of the other party, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments, personnel, information technology systems, and records, and each shall cooperate with the other party in preparing to execute after the Effective Time the conversion or consolidation of systems and business operations generally, and, during such period, each of IBTX and TCBI shall, and shall cause its respective Subsidiaries to, make available to the other party (i) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal securities laws or federal or state banking laws (other than reports or documents that IBTX or TCBI, as the case may be, is not permitted to disclose under applicable law), and (ii) all other information concerning its business, properties and personnel as such party may reasonably request. Neither IBTX nor TCBI nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of IBTX’s or TCBI’s, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) Each of IBTX and TCBI shall hold all information furnished by or on behalf of the other party or any of such party’s Subsidiaries or representatives pursuant to Section 6.2(a) in confidence to the extent required by, and in accordance with, the provisions of the confidentiality agreement, dated November 12, 2019, between IBTX and TCBI (the “Confidentiality Agreement”).

-53-

(c) No investigation by either of the parties or their respective representatives shall affect or be deemed to modify or waive the representations and warranties of the other set forth herein. Nothing contained in this Agreement shall give either party, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time. Prior to the Effective Time, each party shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

6.3 Shareholders’ Approvals. Each of IBTX and TCBI shall call a meeting of its shareholders (the “IBTX Meeting” and the “TCBI Meeting,” respectively) to be held as soon as reasonably practicable after the S-4 is declared effective, for the purpose of obtaining (a) the Requisite TCBI Vote and the Requisite IBTX Vote required in connection with this Agreement and the Merger and (b) if so desired and mutually agreed, a vote upon other matters of the type customarily brought before a meeting of shareholders in connection with the approval of a merger agreement or the transactions contemplated thereby, and each of TCBI and IBTX shall use its reasonable best efforts to cause such meetings to occur as soon as reasonably practicable and on the same date. Each of IBTX and TCBI and their respective Boards of Directors shall use its reasonable best efforts to obtain from the shareholders of IBTX and TCBI, as applicable, the Requisite IBTX Vote and the Requisite TCBI Vote, as applicable, including by communicating to the respective shareholders of IBTX and TCBI its recommendation (and including such recommendation in the Joint Proxy Statement) that, in the case of IBTX, the shareholders of IBTX approve this Agreement (the “IBTX Board Recommendation”), and in the case of TCBI, that the shareholders of TCBI approve this Agreement (the “TCBI Board Recommendation”), IBTX and each of IBTX and TCBI and their respective Boards of Directors shall not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party the IBTX Board Recommendation, in the case of IBTX, or the TCBI Board Recommendation, in the case of TCBI, (ii) fail to make the IBTX Board Recommendation, in the case of IBTX, or the TCBI Board Recommendation, in the case of TCBI, in the Joint Proxy Statement, (iii) adopt, approve, recommend or endorse an Acquisition Proposal or publicly announce an intention to adopt, approve, recommend or endorse an Acquisition Proposal, (iv) fail to publicly and without qualification (A) recommend against any Acquisition Proposal or (B) reaffirm the IBTX Board Recommendation, in the case of IBTX, or the TCBI Board Recommendation, in the case of TCBI, in each case within ten (10) business days (or such fewer number of days as remains prior to the IBTX Meeting or the TCBI Meeting, as applicable) after an Acquisition Proposal is made public or any request by the other party to do so, or (v) publicly propose to do any of the foregoing (any of the foregoing a “Recommendation Change”). However, subject to Section 8.1 and Section 8.2, if the Board of Directors of IBTX or TCBI, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the IBTX Board Recommendation or the TCBI Board Recommendation, as applicable, such Board of Directors may, in the case of IBTX, prior to the receipt of the Requisite IBTX Vote, and in the case of TCBI, prior to the receipt of the Requisite TCBI Vote, submit this Agreement to its shareholders without recommendation (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event such Board of Directors may communicate the basis for its lack of a recommendation to its shareholders in the Joint Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law; provided that such Board of Directors may not take any actions under this sentence unless it (A) gives the other party at least three (3) business days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an Acquisition Proposal, the latest material terms and conditions and the identity of the third party in any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (B) at the end of such notice period, takes into account any amendment or modification to this Agreement proposed by the other party and, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the IBTX Board Recommendation or TCBI Board Recommendation, as the case may be. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3 and will require a new notice period as referred to in this Section 6.3. IBTX or TCBI shall adjourn or postpone the IBTX Meeting or the TCBI Meeting, as the case may be, if, as of the time for which such meeting is originally scheduled there are insufficient shares of IBTX Common Stock or TCBI Common Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting TCBI or IBTX, as applicable, has not received proxies representing a sufficient number of shares necessary to obtain the Requisite TCBI Vote or the Requisite IBTX Vote, and subject to the terms and conditions of this Agreement (including the immediately preceding sentence), TCBI or IBTX, as applicable, shall continue to use reasonable best efforts to solicit proxies from its shareholders in order to obtain the Requisite TCBI Vote or the Requisite IBTX Vote, respectively. Notwithstanding anything to the contrary herein, but subject to the obligation to adjourn or postpone such meeting as set forth in the immediately preceding sentence, unless this Agreement has been terminated in accordance with its terms, (x) the IBTX Meeting shall be convened and this Agreement shall be submitted to the shareholders of IBTX at the IBTX Meeting and (y) the TCBI Meeting shall be convened and this Agreement shall be submitted to the shareholders of TCBI at the TCBI Meeting, and nothing contained herein shall be deemed to relieve either IBTX or TCBI of such obligation.

-54-

6.4 Legal Conditions to Merger. Subject in all respects to Section 6.1 of this Agreement, each of IBTX and TCBI shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its Subsidiaries with respect to the Merger and the Bank Merger and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement, (b) to obtain (and to cooperate with the other party to obtain) any material consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by TCBI or IBTX or any of their respective Subsidiaries in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement, and (c) to obtain the tax opinions referenced in Section 7.2(c) and Section 7.3(c), including by executing and delivering representations contained in certificates of officers of IBTX and TCBI reasonably satisfactory in form and substance to IBTX’s and TCBI’s counsel.

-55-

6.5 Stock Exchange Listing. IBTX shall cause the shares of IBTX Common Stock and New IBTX Preferred Stock to be issued in the Merger to be approved for listing on the NASDAQ, subject to official notice of issuance, prior to the Effective Time.

Prior to the Closing Date, TCBI and IBTX shall cooperate in reviewing, evaluating and analyzing the IBTX Benefit Plans and TCBI Benefit Plans with a view towards developing appropriate New Benefit Plans with respect to continuing employees of IBTX and TCBI, which New Benefit Plans will, to the extent permitted by applicable law, and among other things, (A) treat similarly situated employees on a substantially equivalent basis, taking into account all relevant factors, including duties, geographic location, tenure, qualifications and abilities, and (B) not discriminate between employees who were covered by IBTX Benefit Plans, on the one hand, and those covered by TCBI Benefit Plans, on the other hand, at the Effective Time. Notwithstanding the foregoing, IBTX and TCBI agree that any continuing employee of IBTX or TCBI who, during the period commencing on the Closing Date and ending on the first anniversary thereof, is involuntarily terminated other than for cause by the Surviving Entity or any of its respective Subsidiaries will be provided with severance pay and benefits pursuant to a severance program to be mutually agreed between IBTX and TCBI prior to the Effective Time.

-56-

(b) For purposes of eligibility, participation, vesting and benefit accrual (except not for purposes of benefit accrual under any defined benefit pension plan or to the extent that such credit would result in a duplication of benefits) under the IBTX Benefit Plans, TCBI Benefit Plans and the New Benefit Plans, service with or credited by IBTX, TCBI or any of their respective Subsidiaries or predecessors for Continuing Employees or continuing employees of IBTX or its Subsidiaries shall be treated as service with IBTX to the same extent that such service was taken into account under the analogous TCBI Benefit Plan or IBTX Benefit Plan prior to the Effective Time. With respect to any TCBI Benefit Plan, IBTX Benefit Plan or New Benefit Plan in which any employees of IBTX or TCBI (or their Subsidiaries) prior to the Effective Time first become eligible to participate on or after the Effective Time, and in which such employees did not participate prior to the Effective Time, the Surviving Entity shall: (i) waive all preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous IBTX Benefit Plan or TCBI Benefit Plan, as the case may be, and (ii) provide each such employee and his or her eligible dependents with credit for any co-payments and deductibles paid prior to the Effective Time (or, if later, prior to the time such employee commenced participation in the New Benefit Plan) under an IBTX Benefit Plan or TCBI Benefit Plan (to the same extent that such credit was given under the analogous TCBI or IBTX Benefit Plan) in satisfying any applicable deductible or out-of-pocket requirements under any TCBI Benefit Plan, IBTX Benefit Plan or New Benefit Plan in which such employee first become eligible to participate after the Effective Time.

(a) Each party agrees that it will not, and will cause each of its Subsidiaries and its and their respective officers, directors, employees, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals with respect to any Acquisition Proposal, (ii) engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) provide any confidential or nonpublic information or data to, have or participate in any discussions with any person relating to any Acquisition Proposal or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other agreement (whether written or oral, binding or nonbinding) (other than a confidentiality agreement referred to and entered into in accordance with this Section 6.12) in connection with or relating to any Acquisition Proposal. Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite IBTX Vote, in the case or IBTX, or the Requisite TCBI Vote, in the case of TCBI, a party receives an unsolicited bona fide written Acquisition Proposal, such party may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal if the Board of Directors of such party concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; provided, that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, such party shall have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party. Each party will, and will cause its Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than TCBI or IBTX, as applicable, with respect to any Acquisition Proposal. Each party will promptly (within twenty-four (24) hours) advise the other party following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal), will provide the other party with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received in connection with any such inquiry or Acquisition Proposal, and will keep the other party apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal. Each party shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof.

(b) Nothing contained in this Agreement shall prevent a party or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to an Acquisition Proposal; provided, that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.

6.14 Change of Method. TCBI and IBTX shall be empowered, upon their mutual agreement, at any time prior to the Effective Time, to change the method or structure of effecting the combination of TCBI and IBTX (including the provisions of Article I), if and to the extent they both deem such change to be necessary, appropriate or desirable; provided, however, that no such change shall (i) alter or change the Exchange Ratio or the number of shares of IBTX Common Stock received by holders of TCBI Common Stock in exchange for each share of TCBI Common Stock, (ii) adversely affect the Tax treatment of TCBI’s shareholders or IBTX’s shareholders pursuant to this Agreement, (iii) adversely affect the Tax treatment of TCBI or IBTX pursuant to this Agreement or (iv) materially impede or delay the consummation of the transactions contemplated by this Agreement in a timely manner. The parties agree to reflect any such change in an appropriate amendment to this Agreement executed by both parties in accordance with Section 9.1.

6.15 Restructuring Efforts. If either TCBI or IBTX shall have failed to obtain the Requisite TCBI Vote or the Requisite IBTX Vote at the duly convened TCBI Meeting or IBTX Meeting, as applicable, or any adjournment or postponement thereof, each of the parties shall in good faith use its reasonable best efforts to negotiate a restructuring of the transactions provided for herein (it being understood that neither party shall have any obligation to alter or change any material terms, including the amount or kind of the consideration to be issued to holders of the capital stock of TCBI as provided for in this Agreement, or any term that would adversely affect the tax treatment of the transactions contemplated hereby, in a manner adverse to such party or its shareholders) and/or resubmit this Agreement and the transactions contemplated hereby (or as restructured pursuant to this Section 6.15) to its respective shareholders for approval.

6.16 Takeover Restrictions. None of TCBI, IBTX or their respective Boards of Directors shall take any action that would cause any Takeover Restriction to become applicable to this Agreement, the Merger, or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Merger and the other transactions contemplated hereby from any applicable Takeover Restriction now or hereafter in effect. If any Takeover Restriction may become, or may purport to be, applicable to the transactions contemplated hereby, each party and the members of their respective Boards of Directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Restriction on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Restriction.

6.17 Treatment of TCBI Indebtedness.

(a) Upon the Effective Time, IBTX shall assume the due and punctual performance and observance of the covenants to be performed by TCBI under the agreements set forth on Section 6.17 of the TCBI Disclosure Schedule to the extent set forth in such agreements. In connection therewith, IBTX and TCBI shall cooperate and use reasonable best efforts to execute and deliver any supplemental indentures, officer’s certificates or other documents, and the parties hereto shall cooperate and use reasonable best efforts to provide any opinion of counsel to the trustee thereof, required to make such assumption effective as of the Effective Time.

(b) If requested by IBTX, TCBI shall deliver all notices and take all other actions to facilitate the termination at the Effective Time of all commitments in respect of the Credit Agreement, dated as of December 22, 2015, among TCBI, the lenders party thereto and U.S. Bank National Association, as administrative agent (as in effect from time to time), and the repayment in full on the Closing Date of all obligations, and releases of all Liens securing obligations, in respect of the indebtedness thereunder; provided, that IBTX shall provide any funds required to effect all such repayments at or prior to the Closing. In furtherance and not in limitation of the foregoing, if requested by IBTX, TCBI shall use commercially reasonable efforts to deliver to IBTX at least two business days prior to the Closing Date an executed payoff letter with respect to such credit facility in form and substance customary for transactions of this type, which payoff letter shall, among other things, include the payoff amount.

6.18 Exemption from Liability Under Section 16(b). TCBI and IBTX agree that, in order to most effectively compensate and retain TCBI Insiders, both prior to and after the Effective Time, it is desirable that TCBI Insiders not be subject to a risk of liability under Section 16(b) of the Exchange Act to the fullest extent permitted by applicable law in connection with the conversion of shares of TCBI Common Stock and TCBI Preferred Stock into shares of IBTX Common Stock and New IBTX Preferred Stock in the Merger and the conversion of TCBI Equity Awards into corresponding IBTX Equity Awards in the Merger consistent with Section 1.8 of this Agreement, and for that compensatory and retentive purpose agree to the provisions of this Section 6.18. TCBI shall deliver to IBTX in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of TCBI subject to the reporting requirements of Section 16(a) of the Exchange Act (the “TCBI Insiders”), and the Board of Directors of IBTX and of TCBI, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall reasonably promptly thereafter, and in any event prior to the Effective Time, take all such steps as may be required to cause (in the case of TCBI) any dispositions of TCBI Common Stock, TCBI Preferred Stock or TCBI Equity Awards by the TCBI Insiders, and (in the case of IBTX) any acquisitions of IBTX Common Stock, New IBTX Preferred Stock, or IBTX Equity Awards by any TCBI Insiders who, immediately following the Merger, will be officers or directors of the Surviving Entity subject to the reporting requirements of Section 16(a) of the Exchange Act, in each case pursuant to the transactions contemplated by this Agreement, to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act to the fullest extent permitted by applicable law.

(a) by mutual written consent of IBTX and TCBI;

(b) by either IBTX or TCBI if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Merger or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final and nonappealable order, injunction, decree or other legal restraint or prohibition permanently enjoining or otherwise prohibiting or making illegal the consummation of the Merger or the Bank Merger, unless the failure to obtain a Requisite Regulatory Approval shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such party set forth herein;

-67-

(c) by either IBTX or TCBI if the Merger shall not have been consummated on or before December 31, 2020 (the “Termination Date”), unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such party set forth herein;

(d) by either IBTX or TCBI (provided, that the terminating party is not then in material breach of any representation, warranty, obligation, covenant or other agreement contained herein) if there shall have been a breach of any of the obligations, covenants or agreements or any of the representations or warranties (or any such representation or warranty shall cease to be true) set forth in this Agreement on the part of TCBI, in the case of a termination by IBTX, or IBTX, in the case of a termination by TCBI, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 7.2, in the case of a termination by IBTX, or Section 7.3, in the case of a termination by TCBI, and which is not cured within forty-five (45) days following written notice to TCBI, in the case of a termination by IBTX, or IBTX, in the case of a termination by TCBI, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the Termination Date);

(e) by TCBI, if (i) IBTX or the Board of Directors of IBTX shall have made a Recommendation Change or (ii) IBTX or the Board of Directors of IBTX shall have breached its obligations under Section 6.3 or 6.12 in any material respect; or

-68-

(b) (i) In the event that after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of TCBI or shall have been made directly to the shareholders of TCBI or any person shall have publicly announced (and not withdrawn at least two (2) business days prior to the TCBI Meeting) an Acquisition Proposal, in each case with respect to TCBI and (A) (x) thereafter this Agreement is terminated by either IBTX or TCBI pursuant to Section 8.1(c) without the Requisite TCBI Vote having been obtained (and all other conditions set forth in Section 7.1 and Section 7.3 were satisfied or were capable of being satisfied prior to such termination) or (y) thereafter this Agreement is terminated by IBTX pursuant to Section 8.1(d) as a result of a willful breach, and (B) prior to the date that is twelve (12) months after the date of such termination, TCBI enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then TCBI shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay IBTX, by wire transfer of same-day funds, a fee equal to $115,000,000 (the “Termination Fee”); provided, that for purposes of this Section 8.2(b)(i), all references in the definition of Acquisition Proposal to “twenty-five percent (25%)” shall instead refer to “fifty percent (50%).”

(ii) In the event that this Agreement is terminated by IBTX pursuant to Section 8.1(f), then TCBI shall pay IBTX, by wire transfer of same-day funds, the Termination Fee within two (2) business days of the date of termination.

(c) (i) In the event that after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of IBTX or shall have been made directly to the shareholders of IBTX or any person shall have publicly announced (and not withdrawn at least two (2) business days prior to the IBTX Meeting) an Acquisition Proposal, in each case with respect to IBTX and (A) (x) thereafter this Agreement is terminated by either IBTX or TCBI pursuant to Section 8.1(c) without the Requisite IBTX Vote having been obtained (and all other conditions set forth in Section 7.1 and Section 7.2 were satisfied or were capable of being satisfied prior to such termination) or (y) thereafter this Agreement is terminated by TCBI pursuant to Section 8.1(d) as a result of a willful breach, and (B) prior to the date that is twelve (12) months after the date of such termination, IBTX enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then IBTX shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay TCBI the Termination Fee by wire transfer of same-day funds; provided, that for purposes of this Section 8.2(c)(i), all references in the definition of Acquisition Proposal to “twenty-five percent (25%)” shall instead refer to “fifty percent (50%).”

(ii) In the event that this Agreement is terminated by TCBI pursuant to Section 8.1(e), then IBTX shall pay TCBI, by wire transfer of same-day funds, the Termination Fee within two (2) business days of the date of termination.

-69-

(d) Notwithstanding anything to the contrary herein, but without limiting the right of any party to recover liabilities or damages to the extent permitted herein, in no event shall either party be required to pay the Termination Fee more than once.

(e) Each of IBTX and TCBI acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if IBTX or TCBI, as the case may be, fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, the other party commences a suit which results in a judgment against the non-paying party for the Termination Fee or any portion thereof, such non-paying party shall pay the costs and expenses of the other party (including attorneys’ fees and expenses) in connection with such suit. In addition, if IBTX or TCBI, as the case may be, fails to pay the amounts payable pursuant to this Section 8.2, then such party shall pay interest on such overdue amounts at a rate per annum equal to the “prime rate” published in the Wall Street Journal on the date on which such payment was required to be made for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full.

When a reference is made in this Agreement to Articles, Sections, Exhibits or Schedules, such reference shall be to an Article or Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

-73-

9.11 Assignment; Third-Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other party. Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns. Except as otherwise provided in Section 6.7, this Agreement (including the documents and instruments referred to herein) is not intended to confer upon any person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance herewith without notice or liability to any other person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

9.12 Specific Performance. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and, accordingly, that the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof (including the parties’ obligation to consummate the Merger), in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate and (b) any requirement under any law to post security or a bond as a prerequisite to obtaining equitable relief.

9.13 Severability. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable.

9.14 Confidential Supervisory Information. Notwithstanding any other provision of this Agreement, no disclosure, representation or warranty shall be made (or other action taken) pursuant to this Agreement that would involve the disclosure of confidential supervisory information (including confidential supervisory information as defined in 12 C.F.R. § 261.2(c) and as identified in 12 C.F.R. § 309.5(g)(8)) of a Governmental Entity by any party to this Agreement to the extent prohibited by applicable law. For purposes of clarity, a representation relating to receipt of regulatory approvals on a timely basis shall not be given, or continue to be given, to the extent the reason for it no longer continuing to be accurate involves such confidential supervisory information. To the extent legally permissible, appropriate substitute disclosures or actions shall be made or taken under circumstances in which the limitations of the preceding sentences apply.

-74-

9.15 Delivery by Facsimile or Electronic Transmission. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by means of a facsimile machine or by e‑mail delivery of a “.pdf” format data file, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or e‑mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or e‑mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each party hereto forever waives any such defense.
