AGREEMENT AND PLAN OF REORGANIZATION

THIS AGREEMENT AND PLAN OF REORGANIZATION (“Agreement”) is made and entered into as of the 22^nd day of December, 2011, by and between INDEPENDENT BANK GROUP, INC., a Texas corporation and registered bank holding company with its principal offices in McKinney, Texas (“IBG”), and I BANK HOLDING COMPANY, INC., a Texas corporation and registered bank holding company with its principal offices in Austin, Texas (“I BHC”).

WITNESSETH:

WHEREAS, I BHC owns all of the capital stock of I Bank Texas, SSB, a Texas state savings bank with its principal offices in Austin, Texas (“I Bank”);

WHEREAS, IBG desires to acquire all of the shares of the I BHC common stock, $8.00 par value per share (the “I BHC Stock”) issued and outstanding immediately prior to the Closing Date (as defined in Section 2.01), and all of the options to acquire I BHC Stock (collectively, the “I BHC Options”) outstanding and unexercised immediately prior to the Closing Date, through the merger (the “Merger”) of IBG ACQUISITION CORPORATION, a Texas corporation and wholly owned subsidiary of IBG (“Newco”) with and into I BHC, pursuant to which holders of I BHC Stock and the holders of the I BHC Options will be entitled to receive cash. For purposes of this Agreement, unless otherwise indicated, all references to shares of I BHC Stock and I BHC Options shall mean the shares of I BHC Stock that are issued and outstanding, and the I BHC Options that are outstanding and unexercised, respectively, immediately prior to the Effective Time;

WHEREAS, IBG and I BHC believe that the Merger, as provided for and subject to the terms and conditions set forth in this Agreement and all exhibits, schedules and supplements hereto, is in the best interests of IBG and I BHC and their respective shareholders;

WHEREAS, subsequent to the Merger, IBG will effect the merger of I BHC into IBG, with IBG continuing as the surviving corporation (the “Subsequent Merger”), and the merger of I Bank with and into Independent Bank, McKinney, Texas, a Texas banking association and a wholly-owned subsidiary of IBG (“Independent Bank”), with Independent Bank continuing as the surviving bank (the “Bank Merger”);

WHEREAS, to induce IBG to enter into this Agreement, certain shareholders of I BHC have agreed to execute and deliver to IBG a Voting Agreement pursuant to which these shareholders agree to vote their shares of I BHC Stock in favor of the Merger;

WHEREAS, IBG and I BHC desire to set forth certain representations, warranties and covenants made by each to the other as an inducement to the execution and delivery of this Agreement and certain additional agreements related to the transactions contemplated hereby; and

WHEREAS, the respective boards of directors of IBG and I BHC have approved this Agreement and the proposed transactions substantially on the terms and conditions set forth in this Agreement.

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 I BHC BY IBG

Section 1.01 Merger of Newco with and into I BHC. Subject to the terms and conditions of this Agreement and the Agreement and Plan of Merger to be entered into between I BHC and Newco (the “Merger Agreement”) in the form attached hereto as Exhibit “A”, Newco will merge with and into I BHC pursuant to the provisions of Chapter 10 of the Texas Business Organizations Code (the “TBOC”).

Section 1.02 Effects of the Merger. I BHC shall continue as the corporation resulting from the Merger (the “Resulting Corporation”), and the Merger shall otherwise have the effects set forth in Section 10.008 of the TBOC and as set forth in the Merger Agreement.

Section 1.03 Certificate of Formation and Bylaws. The Certificate of Formation and Bylaws of the Resulting Corporation shall be as set forth in the Merger Agreement.

Section 1.04 Directors and Officers. The directors and officers of the Resulting Corporation shall be as set forth in the Merger Agreement.

Section 1.05 Merger Consideration. At the Effective Time (as defined in Section 1.09) by virtue of this Agreement and without any further action on the part of any holder:

A. Any shares of I BHC Stock that are owned by I BHC (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. All shares of I BHC Stock and all I BHC Options shall be converted into the right to receive from IBG total aggregate consideration of $36,700,000 (the “Aggregate Consideration”). The Aggregate Consideration shall be allocated as follows:

(1) A total of $2,336,189 of the Aggregate Consideration shall be allocated to the holders of the I BHC Options (the “Aggregate Option Consideration”). At the Effective Time, the I BHC Options shall be converted into the right to receive cash from IBG as set forth in Schedule 1.05(B)(1) (the “Option Holder Consideration”).

(2) A total of $34,363,811 of the Aggregate Consideration shall be allocated to the holders of I BHC Stock (the “Aggregate Shareholder Consideration”). At the Effective Time, each share of I BHC Stock shall be converted into the right to receive from IBG $33.2018 in cash (the “Per Share Shareholder Consideration”).

(3) Subject only to dissenter’s rights under Subchapter H of Chapter 10 of the TBOC, all shares of I BHC Stock and all of the I BHC Options 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 I BHC Stock or I BHC Options shall cease to have any rights with respect thereto, except the right to receive the consideration provided for in this Section 1.05.

C. If the Effective Time occurs after April 30, 2012 (other than as a result of (i) failure to obtain regulatory approval on a timely basis due to issues related to a negative condition or negative operations of I BHC or I Bank, or (ii) the failure of I BHC or I Bank to provide on a timely basis to IBG the information needed to prepare and process its regulatory applications), then the Aggregate Consideration shall be increased by an amount equal to the product of (i) the amount of net income per day of I Bank (calculated in accordance with Call Report Instructions) during the month of April 2012, multiplied by (ii) the number of days between May 1, 2012 and the date on which the Effective Time occurs (the “Additional Aggregate Consideration”). 6.39 percent of the Additional Aggregate Consideration shall be allocated to the holders of the I BHC Options, to be further allocated among the holders of I BHC Options pro rata based upon the number of I BHC Options owned as set forth in Schedule 1.05(B)(I). 93.61 percent of the Additional Aggregate Consideration shall be allocated to the holders of I BHC Stock to be further allocated among the holders of I BHC Stock pro rata based upon the number of shares of I BHC Stock owned on the Closing Date. The Additional Aggregate Consideration, if any, as allocated among the holders of the I BHC Options and shares of I BHC Stock, shall be added to, and delivered as part of, the Option Holder Consideration and the Per Share Shareholder Consideration.

D. As of the date of this Agreement, I BHC has cash on hand in the amount of $284,831.61 (the “Cash Amount”). Between the date of this Agreement and the Closing Date, I BHC shall disburse the Cash Amount to pay for the following expenses related to the Merger:

(1) any and all completion bonuses, severance payments, and other payments to employees of I Bank, including without limitation a $37,500 payment to Xxxxx Xxxxxxxx (provided that IBG shall be responsible for any retention bonus or payment to any employees after Closing);

(2) legal fees and expenses incurred by I BHC and/or I Bank in connection with the transactions contemplated by this Agreement; and

(3) accounting fees and expenses incurred by I BHC and/or I Bank in connection with the transactions contemplated by this Agreement.

All such, fees and expenses (the “Transaction Costs”) shall be paid by I BHC in full on the day before the Closing Date. On the Closing Date prior to the Effective Time, I BHC shall pay a dividend to its shareholders in an aggregate amount equal to the difference between (i) the Cash Amount, less (ii) the aggregate amount of the Transaction Costs.

E. In addition to the Aggregate Consideration, at Closing IBG shall pay to I BHC the sum of $300,000.00 which shall be used at Closing by I BHC to discharge its obligations to Sheshunoff & Co. Investment Banking, L.P. (“Sheshunoff”) as described in Section 11.03 (the “Sheshunoff Obligation”)

Section 1.06 Treatment of Newco Stock. Each share of Newco Stock (as defined in Section 4.03) issued and outstanding immediately prior to the Effective Time shall, on and after the Effective Time, be converted into a like number of shares of the Resulting Corporation with the effect that the aggregate number of shares of common stock of the Resulting Corporation outstanding after the

Effective Time shall be equal to the aggregate number of shares of Newco Stock outstanding immediately before the Effective Time, all of which shall continue to be owned by IBG. The authorized number of shares of common stock of the Resulting Corporation shall be the same as the authorized number of shares of Newco Stock immediately prior to the Effective Time.

Section 1.07 Dissenting Shareholders. Notwithstanding anything in this Agreement to the contrary, shares of I BHC Stock that are held by shareholders of I BHC 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; provided, however, in the event that a shareholder of I BHC fails to perfect, withdraws or otherwise loses any such right or remedy granted by the Subchapter H of Chapter 10 of the TBOC, each share of I BHC Stock held by such shareholder shall be converted into and represent only the right to receive the consideration as specified in Section 1.05.

Section 1.08 Exchange of Certificates.

A. At least twenty (20) days prior to the Closing Date (unless IBG and I BHC shall mutually agree in writing to a later date), I BHC shall mail or cause to be mailed to each holder of record of one or more certificates representing shares of I BHC Stock (the “Certificates”) the following: (i) a letter of transmittal (which shall specify that delivery of the Certificates shall be effected, and risk of loss and title to the Certificates shall pass, only upon receipt of the Certificates by IBG) and (ii) instructions for use in effecting the surrender of the Certificates (collectively, the “Transmittal Documents”). The Transmittal Documents shall be addressed to the most current address, according to the books and records of I BHC, of each holder of record of Certificate(s).

B. If a holder of Certificates surrenders such Certificates and a properly executed letter of transmittal to IBG, as paying agent, at least two (2) business days prior to the Closing Date, then, on the Closing Date, IBG will deliver to such holder of Certificates the aggregate Per Share Shareholder Consideration with respect to the Certificates surrendered that such holder is entitled to receive in connection with the Closing pursuant to Section 1.05. If a holder of Certificates surrenders such Certificates and a properly executed letter of transmittal to IBG, as paying agent, at any time after two (2) business days prior to the Closing Date, then IBG will promptly, but in no event later than two (2) business days following receipt of such Certificates and letter of transmittal, deliver to such holder of Certificates the aggregate Per Share Shareholder Consideration with respect to the Certificates surrendered which such holder is entitled to receive in connection with the Closing pursuant to Section 1.05.

C. At or following the Closing, as applicable, pursuant to the exchange procedures set forth in Section 1.08(B), IBG shall deliver the Aggregate Consideration and the Additional Aggregate Consideration, if any, as follows:

(1) To each I BHC shareholder, an amount of cash equal to the product of (i) the Per Share Shareholder Consideration (as increased by the pro rata allocation of the Additional Aggregate Consideration, if any), multiplied by (ii) the number of shares of I BHC Stock represented by the Certificate surrendered by such I BHC shareholder.

(2) To each holder of I BHC Options, an amount of cash as set forth beside their name in Schedule 1.05(B)(1) (as increased by the pro rata allocation of the Additional Aggregate Consideration, if any).

D. In the event that any Certificate shall have been lost, stolen or destroyed, 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, the posting by such person of a bond in such amount as IBG may reasonably determine is necessary as indemnity against any claim that may be made against it with respect to such Certificate, to IBG, as the paying agent, shall deliver in exchange for such lost, stolen or destroyed Certificate the aggregate Per Share Shareholder Consideration payable with respect to such Certificate.

E. Until the holder of Certificates surrenders such Certificates and a properly executed letter of transmittal to IBG, such holder shall not be entitled to receive the Per Share Shareholder Consideration payable with respect to such Certificate. No interest will be paid on the Per Share Shareholder Consideration payable with respect to such Certificate.

F. After the Effective Time, there shall be no further registrations or transfers of Certificates on the stock transfer records of I BHC.

G. Notwithstanding the foregoing, none of IBG, I BHC or the paying agent shall be liable to any holder of I BHC Stock or I BHC Options for any amount delivered in good faith to a public official pursuant to any applicable abandoned property, escheat or similar laws.

Section 1.09 Effective Time. The “Effective Time” as that term is used in this Agreement means the effective time of the Merger as specified in the Certificate of Merger filed with and certified by the Secretary of State of Texas. The Certificate of Merger shall be filed as soon as practicable after the Closing Date.

Section 1.10 Subsequent Merger. Promptly after the Effective Time, and in any event within three (3) business days, IBG shall cause the Subsequent Merger and the Bank Merger to be consummated.

Each of I BHC and I Bank has performed in all material respects all of its duties as a trustee, custodian, guardian or as an escrow agent in a manner that complies in all material respects with all applicable laws, regulations, orders, agreements, instruments and common law standards, where the failure to so perform would result in a Material Adverse Change. To the Best Knowledge of I BHC, there is no reasonable basis for any such Material Adverse Change.

Section 3.28 Guaranties. Except in the ordinary course of business, according to past business practices and in material compliance with applicable law, I BHC or I Bank have not guaranteed the obligations or liabilities of any other person, firm or corporation.

Section 3.29 Employee Benefit Plans.

A. Set forth on Schedule 3.29 is a complete and correct list of all “employee benefit plans” (as defined in Section 3(3) of ERISA), all specified fringe benefit plans as defined in Section 6039D of the Code, and all other bonus, incentive, compensation, deferred compensation, profit 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, currently effective or terminated), and any trust, escrow or other agreement related thereto, which (a) is currently or has been at any time since January 1, 2009, maintained or contributed to by I BHC or I Bank, or with respect to which I BHC or I Bank has any liability, or (b) provides benefits, or describes policies or procedures applicable to any officer, employee, service provider, former officer or former employee of I BHC or I Bank, 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 Section 3(35) of ERISA. I BHC 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 Section 406 of ERISA or Section 4975(c) of the Code), breaches of fiduciary duty or any other breaches or violations of any law applicable to the Employee

Plans and related Funding Arrangements that could reasonably be expected to subject IBG, I BHC or I Bank to any taxes, penalties or other liabilities. Each Employee Plan that is represented to be qualified under Section 401(a) of the Code has a current favorable determination or opinion letter, does not have any amendments for which the remedial amendment period under Code Section 401(b) has expired, and has been operated in material compliance with applicable law and in accordance with its terms. All reports, descriptions and filings required by the Code, ERISA or any government agency with respect to each Employee Plan have been timely and completely filed or distributed. Each Employee Plan has been operated in material compliance with applicable law or in accordance with its terms and any related trust is exempt from federal income tax under Section 501(a) of the Code. 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 I BHC, none are threatened. No written or, to the Best Knowledge of I BHC, oral representations have been made by I BHC or I Bank to any employee or former employee of I BHC or I Bank 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 Section 4980B of the Code). Compliance with FAS 106 will not create any material change to the I BHC Financial Statements or the I Bank Call Reports. Except to the extent that the payment could constitute an “excess parachute payment” under Section 280G of the Code, there are no contracts or arrangements providing for payments that will be nondeductible or subject to excise tax under Code Sections 4999 or 280G, nor will IBG be required to “gross up” or otherwise compensate any person because of the limits contained in such Code sections. There are no surrender charges, penalties, or other costs or fees that could reasonably be expected to be imposed by any person against I BHC, I Bank, 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. With respect to each “employee benefit plan” (as defined in ERISA) maintained or contributed to or required to be contributed to, currently or in the past, by any trade or business with which I BHC or I Bank is required by any of the rules contained in the Code or ERISA to be treated as a single employer (“Controlled Group Plans”):

(i) All Controlled Group Plans which are “group health plans” (as defined in the Code and ERISA) have been operated to the Closing such that failures to operate such group health plans in compliance, in all material respects, with Part 6 of Subtitle B of Title 1 of ERISA and Sections 4980B and 4980D of the Code could reasonably be expected to subject I BHC or I Bank to liability;

(ii) There is no Controlled Group Plan that is a defined benefit plan (as defined in Section 3(35) of ERISA), nor has there been a Controlled Group Plan that is a defined benefit plan in the last five (5) calendar years; and

(iii) There is no Controlled Group Plan that is a “multiple employer plan” or “multi-employer plan” (as either such term is defined in ERISA), nor has there been a Controlled Group Plan that is either a multiple employer plan or multi-employer plan since 2007.

D. All Employee Plan documents, annual reports or returns, audited or unaudited financial statements, actuarial valuations, summary annual reports, and summary plan descriptions issued with respect to the Employee Plans are correct, complete, and current in all material respects, have been timely filed, and there have been no material changes in the information set forth therein.

E. All contributions (including all employer contributions, employee salary reduction contributions and all premiums or other payments (other than claims)) that are due have been made with respect to each Employee Plan.

Section 3.30 No Excess Parachute Payments. No amount, whether in cash or property or vesting of property, that will be received by or benefit provided to, any officer, director or employee of I BHC, I Bank or any of their respective Affiliates who is a “disqualified individual” (as such term is defined in Treasury Regulation 1.280G-1) under any employment, severance or termination agreement, other compensation arrangement or benefit plan currently in effect will be an “excess parachute payment” (as such term is defined in 280G(b)(1) of the Code) solely as a result of the transactions contemplated by this Agreement; and no such person is entitled to receive any additional payment from I BHC, I Bank, or IBG in the event that the excise tax of Section 4999(a) of the Code is imposed on such person.

Section 3.31 Bank Secrecy Act, Foreign Corrupt Practices Act and U.S.A. Patriot Act. I Bank is in material compliance with the Bank Secrecy Act (12 U.S.C. §§ 1730(d) and 1829(b)), the United States Foreign Corrupt Practices Act and the International Money Laundering Abatement and Anti-Terrorist Financing Act, otherwise known as the U.S.A. Patriot Act, and all regulations promulgated thereunder. I Bank has properly certified all foreign deposit accounts and has made all necessary tax withholdings on all of its deposit accounts; furthermore, I Bank has timely and properly filed and maintained all requisite Currency Transaction Reports and other related forms, including any requisite Custom Reports required by any agency of the United States Treasury Department, including the IRS. I Bank has timely filed all Suspicious Activity Reports with the Financial Institutions – Financial Crimes Enforcement Network (U.S. Department of the Treasury) required to be filed by it pursuant to the laws and regulations referenced in this Section.

Section 3.32 Data Processing Agreements. I Bank obtains its data processing services, ATM, and other information technology services exclusively through the contracts or agreements with the persons or entities described on Schedule 3.32 (“DP Contracts”). A true and correct executed copy of each DP Contract, as in effect as of the date hereof, has been provided to IBG. Other than the DP Contracts, I Bank has no agreement with any other person or entity for data processing, ATM or other technology services.

Section 3.33 Proxy/Information Statement. None of the information supplied or to be supplied by I BHC, I Bank or any of their respective directors, officers, employees or agents for inclusion or incorporation by reference in the proxy and/or information statement to be sent to the shareholders of I BHC in connection with the Merger (“Proxy/Information Statement”) will, at the date the Proxy/Information Statement is mailed to the shareholders of I BHC and, as the Proxy/Information Statement may be amended or supplemented, at the time of the I BHC shareholders’ meeting, contain any untrue statement of a material fact or omit to state any material fact with respect to I BHC necessary in order to make the statements therein with respect to I BHC, in light of the circumstances under which they are made, not misleading. All documents that I BHC is responsible for filing with any Regulatory Agency in connection with the Merger will comply, with respect to I BHC, in all material respects with the provisions of applicable law.

Section 3.34 Dissenting Shareholders. To the Best Knowledge of I BHC, there is no plan or intention on the part of any shareholders of I BHC to exercise their appraisal rights in the manner provided by applicable law.

Section 3.35 Fair Housing Act, Home Mortgage Disclosure Act and Equal Credit Opportunity Act. I Bank is in compliance in all material respects with the Fair Housing Act (42 U.S.C. § 3601 et seq.), the Home Mortgage Disclosure Act (12 U.S.C. § 2801 et seq.) and the Equal Credit Opportunity Act (15 U.S.C. § 1691 et seq.) and all regulations promulgated thereunder. Since January 1, 2009, I Bank has not received any written notices of any violation of such acts or any of the regulations promulgated thereunder, and it has not received any written notice of any, and to the Best Knowledge of I BHC there is no, threatened administrative inquiry, proceeding or investigation with respect to its compliance with such laws.

Rev. Civ. Stat. Xxx. Art. 5062-2.01, et seq.) and all statutes governing the operation of banks operating in the State of Texas.

To compensate IBG for entering into this Agreement, taking actions to consummate the transactions contemplated hereunder and incurring the costs and expenses related thereto and other losses and expenses, including foregoing the pursuit of other opportunities, I BHC and IBG agree as follows:

A. Provided that IBG shall not be in material breach of any covenant or obligation under this Agreement (which breach has not been cured promptly following receipt of written notice thereof by I BHC specifying in reasonable detail the basis of such alleged breach), I BHC shall pay to IBG the sum of $1,500,000 (the “Termination Fee”) if this Agreement is terminated (i) by I BHC under the provisions of Section 9.01(J), (ii) by either IBG or I BHC under the provisions of Section 9.01(I), if at the time of any failure by the shareholders of I BHC to approve and adopt this Agreement and the Merger there shall exist an Acquisition Proposal with respect to I BHC and, within twelve months of the termination of this Agreement, I BHC enters into a definitive agreement with any third party with respect to any Acquisition Proposal, or (iii) by IBG under the provisions of Section 9.01(K). I BHC’s obligation to pay the Termination Fee pursuant to this Section 9.04(A) shall survive the termination of this Agreement.

B. Any payment required by Section 9.04(A) shall become payable within ten (10) business days after receipt by the non-terminating party of written notice of termination of this Agreement.

C. For purposes of this Agreement, “Acquisition Proposal” means a written offer or proposal which contains a fixed price per share or a mathematically ascertainable formula for calculating a price per share for the I BHC Stock regarding any of the following (other than the transactions contemplated by this Agreement) involving I BHC or I Bank: (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, I BHC or I Bank, 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; (ii) any tender offer or exchange offer for 50% or more of the outstanding shares of capital stock of I BHC or the filing of a registration statement in connection therewith; or (iii) any public announcement of a proposal, plan or intention to do any of the foregoing or any agreement to engage in any of the foregoing.

D. For purposes of this Agreement, “Superior Proposal” means a bona fide Acquisition Proposal made by a third person that the Board of Directors of I BHC determines in its good faith judgment to be more favorable to I BHC’s shareholders than the Merger (taking into account, in good faith, the written opinion, with only customary qualifications, of I BHC’s independent financial advisor that the value of the consideration to I BHC’s shareholders provided for in such proposal exceeds the value of the consideration to I BHC’s shareholders provided for in the Merger) and for which financing, to the extent required, is then committed or which, in the good faith judgment of the Board of Directors of I BHC (taking into account, in good faith, the written advice of I BHC’s independent financial advisor), is reasonably capable of being obtained by such third person.

MISCELLANEOUS

Section 11.01 No Survival of Representations and Warranties. The parties hereto agree that all of the representations, warranties and covenants contained in this Agreement shall terminate and be extinguished at Closing, except for those covenants that specifically require performance after the Closing. Nothing in this Section 11.01 shall limit or otherwise affect the remedies available to IBG and I BHC with respect to a cause of action arising out of an intentional misrepresentation against the person who made such intentional misrepresentation.

Section 11.02 Expenses. Except as specifically provided in this Agreement, all costs and expenses incurred in connection with this Agreement and all agreements and documents contemplated hereby, and the consummation of the transactions contemplated hereby and thereby, shall be borne and paid by the party incurring such costs or expenses.

Section 11.03 Brokerage Fees and Commissions. IBG hereby represents to I BHC that no agent, representative or broker has represented IBG or Independent Bank in connection with the transactions described in this Agreement. I BHC shall not have any responsibility or liability for any fees, expenses or commissions payable to any agent, representative or broker of IBG or Independent Bank, and IBG hereby agrees to indemnify and hold harmless I BHC for any amounts owed to any agent, representative or broker of IBG or Independent Bank. I BHC hereby represents to IBG that except for an agreement for consulting services with Sheshunoff, a true and correct copy of which, as modified, is included in Schedule 11.03, no agent, representative or broker has represented I BHC or I Bank in connection with the transactions described in this Agreement.

Section 11.04 Entire Agreement. This Agreement (including the documents and instruments referred to herein) and the other agreements, documents, schedules and instruments executed and delivered by the parties to each other at the Closing constitute the full understanding of the parties, a complete allocation of risks between them and a complete and exclusive statement of the terms and conditions of their agreement relating to the subject matter hereof, and supersede any and all prior agreements, whether written or oral, that may exist between the parties with respect thereto. Except as otherwise specifically provided in this Agreement, no conditions, usage of trade, course of dealing or performance, understanding or agreement purporting to modify, vary, explain or supplement the terms or conditions of this Agreement shall be binding unless hereafter or contemporaneously herewith made in writing and signed by the party to be bound, and no modification shall be effected by the acknowledgment or acceptance of documents containing terms or conditions at variance with or in addition to those set forth in this Agreement.

Section 11.06 Severability. If any term or other provision of this Agreement is held to be illegal, invalid or unenforceable by any rule of law or public policy, such term or provision shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision were not a part hereof, and all other conditions and provisions of this Agreement shall remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or unenforceable, there shall be added automatically as a part of this Agreement a provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and still be legal, valid and enforceable.

When a reference is made in this Agreement to an Article, Section, Exhibit or Schedule, such reference shall be to an Article or Section of, or an Exhibit or Schedule to, this Agreement unless otherwise indicated.

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.

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. 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, I BHC or I Bank 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 I BHC, 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 prior to 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 of 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 I BHC shareholders; provided, however, that after the approval of this Agreement by the I BHC shareholders, there shall not be, without the further approval of the I BHC shareholders, any amendment of this Agreement that decreases the consideration to be paid for the I BHC Stock pursuant to Section 1.05 that materially and adversely affects the rights of the I BHC shareholders hereunder. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.
