NOW, THEREFORE, for and in consideration of the foregoing and of the mutual representations, warranties, covenants and agreements contained in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be bound hereby, the parties hereby agree as follows:

ARTICLE I

ACQUISITION OF IBI BY IBG

Section 1.01. Merger of IBI with and into IBG. Subject to the terms and conditions of this Agreement, IBI will merge with and into IBG pursuant to the provisions of Chapter 10 and Chapter 21 of the Texas Business Organizations Code (the “TBOC”).

Section 1.02. Effects of the Merger. The Merger shall have the effects set forth in Section 10.008 of the TBOC. After the Merger, IBG shall continue as the corporation resulting from the Merger (the “Resulting Corporation”), and the separate corporate existence of IBI shall cease. The name of the Resulting Corporation shall be “Independent Bank Group, Inc.” The existing principal office and facilities of IBG immediately preceding the Merger shall be the principal office and facilities of the Resulting Corporation after the Merger. At the Effective Time, all rights, title and interests to all assets, including without limitation real and personal property of any type and choses in action, owned by each of IBG and IBI shall be allocated to and vested in the Resulting Corporation without reversion or impairment, without further act or deed, and without any transfer or assignment having occurred, but subject to any existing liens or encumbrances thereon. At the Effective Time, all liabilities and obligations of IBG and IBI shall be allocated to the Resulting Corporation, and the Resulting Corporation shall be the primary obligor therefor, and no other party to the Merger shall be liable therefor. At the Effective Time, a proceeding pending by or against either IBG or IBI may be continued as if the Merger did not occur, or the Resulting Corporation may be substituted in the proceedings.

Section 1.03. Certificate of Formation and Bylaws. As a result of the Merger, the Certificate of Formation and Bylaws, each as amended, of IBG shall continue in effect as the Certificate of Formation and Bylaws of the Resulting Corporation until the same shall be amended and changed as provided by applicable law.

Section 1.04. Directors and Executive Officers. The directors and executive officers of IBG as of the Effective Time, shall be the directors and executive officers of the Resulting Corporation, and such directors and executive officers shall hold office from the Effective Time until their respective successors are duly elected or appointed and qualified in the manner provided in the Certificate of Formation and Bylaws of the Resulting Corporation or as otherwise provided by applicable law.

Section 1.05. Merger Consideration. At the Effective Time by virtue of this Agreement and without any further action on the part of any holder, all of the IBI Shares outstanding immediately before the Effective Time shall be converted into the right to receive (i) an aggregate of $31,600,000 in cash, subject to adjustment pursuant to Section 1.05(E) (the “Aggregate Cash Consideration”), net of the Aggregate Non-Exercising Option Holder Payment (as defined in Section 1.06(C)(1) below), and (ii) an aggregate 2,072,131 IBG Shares (together with the Aggregate Cash Consideration, the “Aggregate Merger Consideration”).

A. Any IBI Shares that are owned by IBI (other than as a fiduciary) shall automatically be canceled and retired and all rights with respect thereto shall cease to exist, and no consideration shall be delivered in exchange therefor.

B. Each IBI Share issued and outstanding immediately before the Effective Time (excluding IBI Shares cancelled pursuant to Section 1.05(A)) shall be converted into, and shall be cancelled in exchange for, the right to receive the following consideration.

1. A cash amount equal to the quotient of (i) the Shareholder Cash Consideration, divided by (ii) the number of IBI Shares outstanding immediately before the Effective Time (the “Per Share Cash Consideration”). For purposes of this Agreement, “Shareholder Cash Consideration” shall mean the difference between (i) the Aggregate Cash Consideration, less (ii) the Aggregate Non-Exercising Option Holder Payment.

2. A fraction of an IBG Share, rounded to the nearest hundred thousandth, equal to the quotient of (i) 2,072,131 divided by (ii) the number of IBI Shares outstanding immediately before the Effective Time, (the “Per Share Stock Consideration”).

3. Notwithstanding anything in this Agreement to the contrary, IBG will not issue any certificates or scrip representing fractional IBG Shares otherwise issuable pursuant to the Merger. In lieu of the issuance of any such fractional shares, IBG shall pay to each former holder of IBI Shares otherwise entitled to receive such fractional share an amount of cash determined by multiplying (i) the Closing Price, by (ii) the fraction of an IBG Share which such holder would otherwise be entitled to receive pursuant to this Section 1.05(B). For purposes of this Agreement, “Closing Price” shall mean the closing sales price per IBG Share on the NASDAQ Stock Market, Inc. Global Select Market System (“NASDAQ”) on the Calculation Date (as defined in Section 1.05(D) below), as reported by Bloomberg.

C. Subject only to dissenter’s rights under Subchapter H of Chapter 10 of the TBOC at the Effective Time, all IBI Shares shall no longer be outstanding and shall be cancelled and retired and all rights with respect thereto shall cease to exist, and each holder of IBI Shares (a “IBI Shareholder”) shall cease to have any rights with respect thereto, except the right to receive the consideration provided for in this Section 1.05. Certificates previously representing IBI Shares will be exchanged for such consideration upon the surrender of such certificates in accordance with Section 2.04, without interest thereon.

D. If the Tangible Equity (as defined below) on the fifth business day preceding the Closing Date (as defined in Section 2.01) (the “Calculation Date”) is greater than $84,000,000, then, on the Closing Date, IBI may distribute to its shareholders an amount equal to the difference between (i) the actual amount of Tangible Equity as of the Calculation Date, less (iii) $84,000,000. Any such distribution is referred to as the “Section 1.05(D) Distribution.”

For purposes of this Agreement, “Tangible Equity” means the tangible shareholders’ equity of IBI as determined from IBI’s financial statements prepared in accordance with generally accepted accounting principles, consistently applied. The following items shall have been paid or properly accrued for, on an after tax basis, in the calculation of Tangible Equity:

1. All professional fees incurred by IBI and Integrity Bank in connection with the transactions contemplated by this Agreement, including investment banking fees, legal fees, accounting fees, and similar costs and expenses;

2. Costs and fees associated with the termination and de-conversion of material contracts of IBI and Integrity Bank, including their respective data processing and other IT contracts as well as the costs and fees described in Confidential Schedule 1.05(D)(2);

3. All payments made or owed to directors, officers and employees of IBI and Integrity Bank related to the consummation of the Merger, including without limitation bonuses, change in control payments, payments due under employment contracts or arrangements, unfunded payments due under deferred compensation arrangements, director long term care insurance payments, “stay” or “retention bonuses” paid by IBI or Integrity Bank, or similar compensation payments;

4. The premium for D&O insurance tail coverage contemplated under Section 5.21;

5. The portion of the payroll and income tax owed by IBI or Integrity Bank, if any, resulting from (i) any payment contemplated by Section 1.05(D)(3) above, and (ii) the payment of the Non-Exercising Option Holder Payment, if any, in connection with the cancellation of unexercised Options as provided for in Section 1.06(C); and

6. The provision expense, if any, incurred by Integrity Bank necessary to comply with Section 5.06.

Unrealized gains and losses on IBI’s investment securities shall be excluded from the calculation of Tangible Equity.

IBI shall, at least three business days before the Closing Date, provide IBG with a calculation of Tangible Equity as of the Calculation Date. If IBG disagrees with such calculation of Tangible Equity, IBI and IBG shall meet to resolve any such disagreement. If IBI and IBG cannot resolve any such disagreement, then an independent accounting firm mutually agreed to by IBG and IBI shall resolve any such disagreement which resolution shall be final and binding upon IBI and IBG. Confidential Schedule 1.05(D) sets forth the method of calculation and, by way of example only, a preliminary estimate of Tangible Equity.

E. If the Tangible Equity on the Calculation Date is less than $84,000,000, then the Aggregate Cash Consideration shall be reduced by an amount equal to the difference between (i) $84,000,000, less (ii) the Tangible Equity on the Calculation Date.

Section 1.06. Treatment of Options. As represented by IBI in Section 3.03, IBI has granted options to purchase IBI Shares (the “Options”). A list of the Options which are unexercised and outstanding as of the date of this Agreement is set forth in Confidential Schedule 3.03(C). The Options shall be subject to the following treatment:

A. Upon approval of this Agreement and the Merger by the shareholders of IBI, each Option that is not vested and exercisable shall become fully vested and exercisable.

B. Each holder of an Option (an “Option Holder”) may exercise his or her outstanding vested Options prior to the Calculation Date pursuant to the terms and procedures set forth in the Integrity Bank SSB 2007 Stock Option Plan and related Stock Option Agreement. The IBI Shares issued upon the exercise of Options shall be converted into the right to receive the consideration set forth in Section 1.05 upon consummation of the Merger.

C. If an Option Holder does not exercise his or her Options prior to the Calculation Date (a “Non-Exercising Option Holder”), any such Non-Exercising Option Holder shall be entitled to receive, for each share of IBI common stock underlying their unexercised and outstanding Option (an “Option Share”), an amount equal to the difference between (i) the Per Share Transaction Value, minus (ii) the applicable exercise price per Option Share as set forth on Confidential Schedule 3.03(C) (the “Per Option Share Price”). For purposes of this Agreement:

“Per Share Transaction Value” shall mean the quotient of (i) the sum of (x) the Aggregate Cash Consideration, plus (y) the Stock Consideration Value, plus (z) the aggregate exercise price to be paid to exercise all of the unexercised Options outstanding on the Calculation Date; divided by (ii) the Diluted IBI Shares.

“Stock Consideration Value” shall mean the product of (i) 2,072,131, multiplied by (ii) the Closing Price.

“Diluted IBI Shares” shall mean the sum of (i) the number of IBI Shares issued and outstanding on the Calculation Date, plus (ii) the number of Option Shares outstanding and unexercised on the Calculation Date.

1. Within five (5) business days following the Closing Date, IBG shall pay to each Non-Exercising Option Holder an amount in cash equal to the product of (i) the Per Option Share Price, multiplied by (ii) the total number of Option Shares held by such Non-Exercising Option Holder (the “Non-Exercising Option Holder Payment”). The aggregate Non-Exercising Option Holder Payment paid to all of the Non-Exercising Option Holders is referred to as the “Aggregate Non-Exercising Option Holder Payment.”

2. A Non-Exercising Option Holder’s right to receive the Non-Exercising Option Holder Payment is subject to their execution and delivery to IBG of an Option Cancellation Agreement in the form of Exhibit A on or before the Calculation Date.

3. To the extent that any unexercised and outstanding Option has an exercise price per share that is greater than the Option Share Price, any such Option shall be cancelled in exchange for no consideration.

4. The Non-Exercising Option Holder Payment shall be subject to applicable payroll, federal, state, and local income tax withholding and, as a result, the amount of the Non-Exercising Option Holder Payment shall be reduced by the applicable total tax withholding, and IBG shall deliver such withheld amount to the applicable taxing authority.

Section 1.07. Treatment of IBG Shares. Each IBG Share outstanding immediately prior to the Effective Time shall, on and after the Effective Time, remain issued and outstanding as one share of common stock of IBG as the corporation surviving the Merger.

Section 1.08. Dissenting Shareholders. Notwithstanding anything in this Agreement to the contrary, IBI Shares that are held by shareholders of IBI who have complied with the terms and provisions of Subchapter H of Chapter 10 of the TBOC (each a “Dissenting Shareholder”) shall be entitled to those rights and remedies set forth in Subchapter H of Chapter 10 of the TBOC; but if a shareholder of IBI fails to perfect, withdraws or otherwise loses any such right or remedy granted by the Subchapter H of Chapter 10 of the TBOC, each IBI Share held by such shareholder shall be converted into and represent only the right to receive the consideration as specified in Section 1.05.

Section 1.09. SEC Filing and Shareholder Approval.

A. As promptly as practicable following the date of this Agreement, IBG shall prepare a registration statement on Form S-4 or other applicable form (the “Registration Statement”) to be filed by IBG with the Securities and Exchange Commission (“SEC”) in connection with the issuance of the IBG Shares to the IBI Shareholders pursuant to Section 1.05 (including the Proxy Statement for the shareholder meeting of IBI and prospectus and other proxy solicitation materials constituting a part thereof (together, the “Proxy Statement”) and all related documents). IBI shall prepare and furnish to IBG such information relating to IBI and its directors, officers and shareholders as may be reasonably required to comply with SEC rules and regulations in connection with the Registration Statement. IBG shall provide IBI, and its legal,

financial and accounting advisors, the right to review and provide comments upon (i) the Registration Statement in advance of such Registration Statement being filed with the SEC and (ii) on all amendments and supplements to the Registration Statement and all responses to requests for additional information and replies to comments relating to the Registration Statement before filing or submission to the SEC. IBG shall consider in good faith all comments from IBI and its legal, financial and accounting advisors to the Registration Statement, all amendments and supplements thereto and all responses to requests for additional information. IBI agrees to cooperate with IBG and IBG’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from its financial advisor and independent auditor and in taking such other actions in connection with the Registration Statement and the Proxy Statement. If IBI has cooperated and promptly provided information required to be delivered by it for inclusion in the Registration Statement and Proxy Statement as required by this Section 1.09(A) and Section 5.02, IBG shall file, or cause to be filed, the Registration Statement with the SEC on or before January 31, 2018. IBG shall use its commercially reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act of 1933, as amended (the “Securities Act”), as promptly as reasonably practicable after the filing thereof. IBG also agrees to use its commercially reasonable efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions contemplated by this Agreement.

B. The Board of Directors of IBI (the “IBI Board”) shall duly call, give notice of, and cause to be held, a meeting of its shareholders (the “IBI Meeting”) and will direct that this Agreement and the transactions contemplated hereby be submitted to a vote at the IBI Meeting. Specifically, the IBI Board will present for the consideration of IBI shareholders a proposal to approve and adopt this Agreement and the Merger and the transactions contemplated hereby. The IBI Board will (i) cause proper notice of the IBI Meeting to be given to the IBI shareholders in compliance with applicable law and regulations, (ii) distribute to the IBI shareholders the Proxy Statement, (iii) recommend by the affirmative vote of the IBI Board a vote in favor of approval of the proposals set forth in this Section 1.09(B), subject to Section 1.09(C), and (iv) perform such other acts as may reasonably necessary to ensure that shareholder approval of the proposals set forth in this Section 1.09(B) are obtained. IBI shall print and commence the mailing (at its expense) of the Proxy Statement to its shareholders on or before the fifth business day after the date that the Registration Statement is declared effective and a final prospectus (relating to the Registration Statement) and Proxy Statement is on file with the SEC before such mailing.

C. Notwithstanding the foregoing, IBI and the IBI Board are permitted to change its recommendation as contemplated by this Section 1.09(C) (“Change in Recommendation”) if and only to the extent that:

Section 2.04. Exchange Procedures.

A. On the business day before the Closing Date, IBG shall deposit or cause to be deposited in trust with ▇▇▇▇▇ Fargo Bank, N.A. (the “Exchange Agent”) the Shareholder Cash Consideration and the IBG Shares in book entry form which the holders of IBI Shares are entitled to receive pursuant to Section 1.05.

B. As soon as practicable after the Effective Time, with the intent to be within five business days after the Effective Time, IBG shall use commercially reasonable efforts to cause the Exchange Agent to mail to each record holder of an outstanding certificate or

certificates representing IBI Shares (the “Certificates”), a form letter of transmittal which will specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and contain instructions for use in effecting the surrender of the Certificates for payment therefor. The form and substance of the letter of transmittal and any associated cover letter shall be mutually acceptable to IBG and IBI before such transmittal materials are mailed to the holders of the Certificates. Upon surrender to the Exchange Agent of a Certificate, together with such letter of transmittal properly completed and duly executed (the “Transmittal Materials”), the holder of such Certificate shall be entitled to receive in exchange therefor (i) the Per Share Cash Consideration and the Per Share Stock Consideration, each, multiplied by the number of IBI Shares represented by the Certificate (the “Surrendered Shares”), and (ii) an amount of cash as payment in lieu of the issuance of fractional IBG Shares calculated in accordance with Section 1.05(B)(3), and such Certificate shall forthwith be canceled. The consideration to be received by an IBI Shareholder upon surrender of his Certificate(s) is referred to as the “Merger Consideration.” Until surrendered in accordance with this Section 2.04, each Certificate (other than Certificates representing IBI Shares held by Dissenting Shareholders) shall represent for all purposes the right to receive the Merger Consideration without any interest thereon. Promptly after receipt of the Transmittal Materials, IBG will use commercially reasonable efforts to cause the Exchange Agent to review the Transmittal Materials in order to verify proper completion and execution thereof. As soon as practicable after the Effective Time and the surrender of a Certificate to the Exchange Agent, together with properly completed and executed Transmittal Materials, IBG will use commercially reasonable efforts to cause the Exchange Agent to promptly deliver the Merger Consideration.

C. After the Effective Time, the share transfer ledger of IBI shall be closed and there shall be no transfers on the share transfer books of IBI of the IBI Shares which were outstanding immediately before such time of filing. If, after the Effective Time, Certificates are presented to IBG, they shall be promptly presented to the Exchange Agent and exchanged as provided in this Section 2.04.

D. Former shareholders of IBI shall be entitled to vote after the Effective Time at any meeting of IBG’s shareholders the number of IBG Shares into which their IBI Shares are converted, regardless of whether such shareholders of IBI have surrendered their Certificates in exchange therefor.

E. No dividends or other distributions declared after the Effective Time with respect to IBG Shares and payable to the holders thereof shall be paid to the holder of a Certificate until such holder surrenders such Certificate to the Exchange Agent in accordance with this Section 2.04. After the surrender of a Certificate in accordance with this Section 2.04, the holder thereof shall be entitled to receive any such dividends or other distributions, without interest thereon, which had become payable after the Effective Time with respect to the IBG Shares represented by such Certificate.

F. Any portion of the Aggregate Merger Consideration (including the proceeds of any investments thereof) that remains unclaimed by the shareholders of IBI for six months after the Exchange Agent mails the letter of transmittal pursuant to this Section 2.04 shall be delivered to IBG upon demand, and any shareholders of IBI who have not theretofore

complied with the exchange procedures in this Section 2.04 shall look to IBG only, and not the Exchange Agent, for the payment of the Merger Consideration in respect of such shares. If outstanding Certificates for IBI Shares are not surrendered or the payment for them is not claimed before the date on which such IBG Shares or cash would otherwise escheat to any governmental unit or agency, the unclaimed items shall, to the extent permitted by abandoned property or any other applicable law, become the property of IBG (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any person previously entitled to such property.

G. If any IBG Shares are to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the Certificate so surrendered shall be appropriately endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form (reasonably satisfactory to IBG) for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other taxes required by reason of the issuance of a certificate representing IBG Shares in any name other than that of the registered holder of the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or not payable.

H. None of IBG, IBI, the Exchange Agent or any other person shall be liable to any former holder of IBI Shares for any IBG Share (or dividends or distributions with respect thereto) or cash properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

I. If any Certificate has been lost, stolen or destroyed, then upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by IBG or the Exchange Agent, the posting by such person of a bond in such amount as IBG or the Exchange Agent may direct (not to exceed the amount of Merger Consideration relating to the relevant missing Certificate) as indemnity against any claim that may be made against IBG, Independent Bank, or IBI with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration deliverable in respect thereof pursuant to this Agreement.

sharing, stock option, stock appreciation right, stock bonus, stock purchase, employee stock ownership, savings, severance, supplemental unemployment, layoff, salary continuation, retirement, pension, health, life insurance, disability, group insurance, vacation, holiday, sick leave, fringe benefit or welfare plan, or any other similar plan, agreement, policy or understanding (whether written or oral, qualified or nonqualified), and any trust, escrow or other agreement related thereto, which (a) is currently maintained or contributed to by IBI or any IBI Subsidiary, or with respect to which IBI or any IBI Subsidiary has any liability, and (b) provides benefits to any officer, employee, service provider, former officer or former employee of IBI or any IBI Subsidiary, or the dependents of any thereof, regardless of whether funded or unfunded (herein collectively the “Employee Plans” and each individually an “Employee Plan”).

B. No Employee Plan is a defined benefit plan within the meaning of ERISA. IBI has delivered or made available to IBG true, accurate and complete copies of the documents comprising each Employee Plan and any related trust agreements, annuity contracts, insurance policies or any other funding instruments (“Funding Arrangements”), any contracts with independent contractors (including actuaries and investment managers) that relate to any Employee Plan, the Form 5500 filed with the IRS in each of the three (3) most recent plan years with respect to each Employee Plan, and related schedules and opinions, and such other documents, records or other materials related thereto, as reasonably requested by IBG. There have been no prohibited transactions (described under ERISA §406 or Code §4975(c)), breaches of fiduciary duty or any other breaches or violations of any law applicable to the Employee Plans and related Funding Arrangements that would reasonably be expected to subject IBG, Independent Bank, IBI or any IBI Subsidiary to any material taxes, penalties or other liabilities. Each Employee Plan that is represented to be qualified under Code §401(a) has a current favorable determination or opinion letter.

Each Employee Plan has been operated in material compliance with applicable law or in accordance with its terms. There are no pending claims, lawsuits or actions relating to any Employee Plan (other than ordinary course claims for benefits) and, to the Best Knowledge of IBI, none are threatened. No written or, to the Best Knowledge of IBI, oral representations have been made by IBI or any IBI Subsidiary to any employee or former employee of IBI or any IBI Subsidiary promising or guaranteeing any employer payment or funding for the continuation of medical, dental, life or disability coverage for such person, their dependent, or any beneficiary for any period of time beyond the end of the current plan year or beyond termination of employment (except to the extent of coverage required under Code §4980B or applicable state law). Compliance with FAS 106 will not create any material change to the Financial Statements or the Call Reports. There are no material surrender charges, penalties, or other costs or fees that would reasonably be expected to be imposed by any person against IBI, any IBI Subsidiary, an Employee Plan, or any other person, including an Employee Plan participant or beneficiary, as a result of the consummation of the transactions contemplated by this Agreement with respect to any insurance, annuity or investment contracts or other similar investment held by any Employee Plan.

C.

No investigation by IBG or its representatives shall affect the representations and warranties set forth herein; provided, however, that IBG shall promptly notify IBI to the extent that IBG’s investigation determines that any of the representations and warranties by IBI set forth in ARTICLE III are untrue.

Section 5.06. Allowance for Loan Losses.

Section 5.10. No Negotiation with Others.

A. IBI agrees that it shall not, and that it shall cause each IBI Subsidiary and the respective employees, directors, officers, financial advisors and agents of IBI and Integrity Bank (collectively, “IBI Representatives”) not to (i) solicit, knowingly encourage, initiate or participate in any negotiations or discussions with any third party (except for the limited purpose of notifying such person of the existence of the provisions of this Section 5.10) regarding an Acquisition Proposal (as defined below), whether by acquisition, business combination, purchase of securities or assets or otherwise; (ii) disclose to any third party any information concerning the

business, Properties, books or records of IBI or any IBI Subsidiary in connection with any Acquisition Proposal, other than as provided herein or as compelled by law; or (iii) cooperate with any third party to make any Acquisition Proposal, other than the sale by IBI or any IBI Subsidiary of assets in the ordinary course of business consistent with past practices. Promptly upon receipt of any unsolicited offer for an Acquisition Proposal, IBI will communicate to IBG the terms of any proposal or request for information and the identity of the parties involved.

B. Notwithstanding anything to the contrary contained in this Section 5.10, if at any time after the date hereof and before the Closing, IBI and the IBI Representatives, having each theretofore complied with the terms of Section 5.10(A), receives a bona fide, unsolicited written Acquisition Proposal, IBI and the IBI Representatives may engage in negotiations and discussions with, and furnish any information and other access (so long as all such information and access has previously been made available to IBG or is made available to IBG before or concurrently with the time such information or access is made available to such person) to, any person making such Acquisition Proposal if, and only if, the IBI Board determines in good faith, after consultation with outside legal and financial advisors, that (i) such Acquisition Proposal is or is reasonably capable of becoming a Superior Proposal (as defined below) and (ii) the failure of the IBI Board to furnish such information or access or enter into such discussions or negotiations would reasonably be expected to be materially inconsistent with its fiduciary duties to the IBI shareholders; but before furnishing any material nonpublic information, IBI shall have received from the person making such Acquisition Proposal an executed confidentiality agreement with terms at least as restrictive in all material respects on such person as the Nondisclosure Agreement entered into with IBG on May 2, 2017, which confidentiality agreement shall not prohibit IBI from complying with the terms of this Section 5.10. IBI will promptly, and in any event within two business days, (x) notify IBG in writing of the receipt of such Acquisition Proposal or any request for nonpublic information relating to IBI or for access to the Properties, books or records of IBI by any person that has made, or to the Best Knowledge of IBI may be considering making, an Acquisition Proposal and (y) communicate the material terms of such Acquisition Proposal to IBG, including as they may change upon any modification or amendment to the terms thereof. IBI will keep IBG reasonably apprised of the status of and other matters relating to any such Acquisition Proposal on a timely basis.

C. Nothing contained in this Section 5.10 shall prevent IBI or the IBI Board from (i) taking the actions provided in Sections 1.09(C) or 5.10(B), (ii) responding to an unsolicited bona fide Acquisition Proposal for the sole purpose of clarifying the terms and conditions of the Acquisition Proposal, (iii) informing any person who submits an unsolicited bona fide Acquisition Proposal of IBI’s obligations pursuant to Section 5.10(A) or (iv) in consultation with outside counsel, complying with its disclosure obligations under federal or state law in connection with a Change in Recommendation.

D. For purposes of this Agreement, “Acquisition Proposal” means a written offer or proposal from a party other than IBG which contains a fixed price per share or a mathematically ascertainable formula for calculating a price per share for the IBI Share regarding any of the following (other than the transactions contemplated by this Agreement) involving IBI: (i) any merger, reorganization, consolidation, share exchange, recapitalization, business combination, liquidation, dissolution or other similar transaction involving any sale, lease, exchange, mortgage, pledge, transfer or other disposition of all or substantially all of the

assets or equity securities or deposits of, IBI, in a single transaction or series of related transactions which could reasonably be expected to impede, interfere with, prevent or materially delay the completion of the Merger; or (ii) any tender offer or exchange offer for 50% or more of the outstanding IBI Shares or the filing of a registration statement in connection therewith.

E. For purposes of this Agreement, “Superior Proposal” means a bona fide Acquisition Proposal made by a party other than IBG that the IBI Board determines in its good faith judgment, after consultation with its outside counsel and its independent financial advisor (i) is or would result in a transaction that if consummated would be more favorable to IBI’s shareholders from a financial point of view than the Merger, taking into account all of the terms and conditions of such proposal and of this Agreement (including any proposal by IBG to amend the terms of this Agreement) and (ii) is capable of being, and is reasonably likely to be, consummated on the terms so proposed taking into account all financial, regulatory, legal and other aspects of such proposal.

Section 5.11. Non-Governmental Consents and Approvals. IBI shall use commercially reasonable efforts to obtain all consents and approvals from third parties listed on Confidential Schedule 3.05. IBI will cooperate in all commercially reasonable respects with IBG to obtain all such approvals and consents required of IBG.

A. IBG and its consultants, agents and representatives, at the sole cost and expense of IBG, shall have the right to the same extent that IBI has the right, but not the obligation or responsibility, to inspect any Property, including conducting asbestos surveys and sampling, environmental assessments and investigation, and other environmental surveys and analyses including soil and ground sampling (“Environmental Inspections”). IBG shall notify IBI in writing before any Environmental Inspection, and IBI may place reasonable restrictions on the time of such Environmental Inspection. If, as a result of any such Environmental Inspection, further investigation (“Secondary Investigation”) including, test borings, soil, water and other sampling is deemed desirable by IBG, IBG shall (i) notify IBI in writing of any Property for which it intends to conduct such a Secondary Investigation and the reasons for the Secondary Investigation, and (ii) at the sole cost and expense of IBG, commence the Secondary Investigation. IBG shall give reasonable written notice to IBI of the Secondary Investigation, and IBI may place reasonable time and place restrictions on the Secondary Investigation.

C. IBG shall have the right to terminate this Agreement by providing written notice to IBI within ninety (90) days following the date of this Agreement if, with respect to the Properties (as defined in Section 11.10) only, (i) the factual substance of any warranty or representation set forth in Section 3.22 is not materially true and accurate; (ii) the results of an Environmental Inspection or Secondary Investigation are disapproved by IBG because such Environmental Inspection or Secondary Investigation identifies material violations Environmental Laws that would result in a Material Adverse Change to IBI or any IBI Subsidiary; (iii) IBI has refused to allow IBG to conduct an Environmental Inspection or Secondary Investigation in a manner that IBG reasonably considers necessary; (iv) the Environmental Inspection or Secondary Investigation identifies any past or present event, condition or circumstance that would result in a Material Adverse Change to IBI or any IBI Subsidiary; (v) the Environmental Inspection or Secondary Investigation identifies the presence of any underground or above ground storage tank in, on or under any Property that is not shown to be in material compliance with all Environmental Laws applicable to the tank either at the date of this Agreement or at a future time certain, or that has had a release of petroleum or some other Hazardous Material that has not been cleaned up to the satisfaction of the relevant Governmental Authority or any other party with a legal right to compel cleanup; or (vi) the Environmental Inspection or Secondary Investigation identifies the presence of any asbestos-containing material in, on or under any Property, the removal of which would result in a Material Adverse Change. IBG shall advise IBI in writing (the “Environmental Notice”) as to whether IBG intends to terminate this Agreement pursuant to this Section 5.12(C). Upon receipt of the Environmental Notice, IBI shall have the opportunity to correct any objected to violations or conditions to IBG’s reasonable satisfaction within 30 days after the date of the Environmental Notice.

Section 5.13. Employee Plans and Employee Contracts. Before the Closing Date, IBI shall and shall cause each IBI Subsidiary to terminate the Employee Plans subject to compliance with applicable law, so long as any such action preserves the rights of the participants in such Employee Plans (including vesting rights). Prior to Closing, IBI and each IBI Subsidiary shall accrue for or make the payments required pursuant to the Employment Contracts as set forth in Confidential Schedule 3.20, and use commercially reasonable efforts to obtain from each applicable officer an acknowledgement regarding the termination of their Employment Contract in connection with the transactions contemplated by this Agreement (the “Employment Contract Acknowledgements”).

Each of the parties hereto acknowledges that the other party would be irreparably damaged and would not have an adequate remedy at law for money damages if any of the covenants contained in this Agreement were not performed in accordance with its terms or otherwise were materially breached. Each of the parties hereto therefore agrees that, without the necessity of proving actual damages or posting bond or other security, the other party shall be entitled to seek temporary and/or permanent injunction or injunctions to prevent breaches of such performance and to specific enforcement of such covenants in addition to any other remedy to which such other party may be entitled, at law or in equity.

Section 11.12. Attorneys’ Fees and Costs.

Section 11.13. Rules of Construction. When a reference is made in this Agreement to an Article, Section, Exhibit or Confidential Schedule, such reference shall be to an Article or Section of, or an Exhibit or Confidential Schedule to, this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision in this Agreement. Each use herein of the masculine, neuter or feminine gender shall be deemed to include the other genders. Each use herein of the plural shall include the singular and vice versa, in each case as the context requires or as is otherwise appropriate. The word “or” is used in the inclusive sense. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein. References to a person are also to its permitted successors or assigns.

Section 11.14. Binding Effect; Assignment. All of the terms, covenants, representations, warranties and conditions of this Agreement shall be binding upon, and inure to the benefit of and be enforceable by, the parties hereto and their respective heirs, successors, representatives and permitted assigns. Nothing expressed or referred to herein is intended or shall be construed to give any person other than the parties hereto any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provision herein contained, it being the intention of the parties hereto that this Agreement, the assumption of obligations and statements of responsibilities hereunder, and all other conditions and provisions hereof are for the sole benefit of the parties to this Agreement and for the benefit of no other person. Nothing in this Agreement shall act to relieve or discharge the obligation or liability of any third party to any party to this Agreement, nor shall any provision give any third party any right of subrogation or action over or against any party to this Agreement. Notwithstanding any other provision of this Agreement, it is specifically intended by the parties to this Agreement that the persons entitled to the benefits of the covenants contained in Section 6.15 and Section 6.16 are third-party beneficiaries solely with respect to such sections. No party to this Agreement shall assign this Agreement, by operation of law or otherwise, in whole or in part, without the prior written consent of the other party. Any assignment made or attempted in violation of this Section 11.14 shall be void and of no effect.

Section 11.15. Public Disclosure. None of IBG, Independent Bank, IBI or any IBI Subsidiary will make, issue or release, or cause to be made, issued or released, any announcement, statement, press release, acknowledgment or other public disclosure of the existence, terms, conditions or status of this Agreement or the transactions contemplated hereby without the prior written consent of the other parties to this Agreement. Notwithstanding the foregoing, IBG and IBI, upon prior notice to the other party, will be permitted to make (i) disclosure to their own officers, directors, employees and shareholders, and (ii) any public disclosures or governmental filings as legal counsel may deem necessary to maintain compliance with or to prevent violations of applicable federal or state laws or regulations or that may be necessary to obtain regulatory approval for the transactions contemplated hereby.

Section 11.16. Extension; Waiver. At any time before the Closing Date, the parties hereto, by action taken or authorized by their respective boards of directors, may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other party hereto, (ii) waive any inaccuracies in the representations and warranties contained herein or in any document, certificate or writing delivered pursuant hereto or (iii) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party in the manner provided in Section 11.17, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. No party to this Agreement shall by any act (except by a written instrument given pursuant to Section 11.17) be deemed to have waived any right or remedy hereunder or to have acquiesced in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising any right, power or privilege hereunder by any party hereto shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver of any party of any right or remedy on any one occasion shall not be construed as a bar to any right or remedy that such party would otherwise have on any future occasion or to any right or remedy that any other party may have hereunder.

Section 11.17. Amendments. This Agreement may be amended by the parties hereto, by action taken or authorized by their respective boards of directors, at any time before or after approval of this Agreement by the IBI shareholders; but after the approval of this Agreement by the IBI shareholders, there shall not be, without the further approval of the IBI shareholders, any amendment of this Agreement that decreases the consideration to be paid for the IBI Shares pursuant to Section 1.05 that materially and adversely affects the rights of the IBI shareholders hereunder. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

OPTION CANCELLATION AGREEMENT

Independent Bank Group, Inc.

▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇., ▇▇▇▇▇ ▇▇▇

▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇

Gentlemen:

Reference is hereby made to that certain Agreement and Plan of Reorganization, dated as of November , 2017 (the “Reorganization Agreement”) by and between Independent Bank Group, Inc. (“IBG”) and Integrity Bancshares, Inc. (“IBI”). Terms with their initial letter capitalized and not otherwise defined herein have the meanings given them in the Reorganization Agreement.

I have previously been granted options (the “Options”) to acquire shares of IBI common stock as set forth on Schedule 1 attached to this Option Cancellation Agreement. I have no other options or rights to acquire shares of common stock or other securities of IBI or Integrity Bank. Pursuant to the Reorganization Agreement, all of my Options that were previously unvested are now fully vested.

I have elected not to exercise my Options. Accordingly, upon consummation of the merger contemplated by the Reorganization Agreement, my Options will be converted into the right to receive cash in the amount of the Non-Exercising Option Holder Payment. I recognize that the receipt of the Non-exercising Option Holder Payment is subject to federal income tax and FICA withholding.

As long as the Reorganization Agreement is in effect, I agree not to exercise any of my Options. I agree to accept the Non-Exercising Option Holder Payment provided for in the Reorganization Agreement and as described herein in full satisfaction of my rights with respect to my Options and as consideration for the termination and cancellation of my Options. I understand and agree that this Option Cancellation Agreement amends my rights with respect to the Options so that, upon consummation of the transactions contemplated by the Reorganization Agreement, my Options shall terminate and be cancelled, and will represent solely the right to receive the Non-Exercising Option Holder Payment provided for in the Reorganization Agreement. I further agree to take such additional actions and deliver such additional documents and certificates as may be reasonably requested by IBG to effect the transactions described in this Option Cancellation Agreement and in the Reorganization Agreement pertaining to the Options.

Very truly yours,
