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:

Section 1.01. Merger of CBI with and into IBG. Subject to the terms and conditions of this Agreement, CBI 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 CBI 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 real estate and other property owned by each of IBG and CBI 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 CBI 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 CBI 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. Subject to the election of the CBI Nominees as contemplated in Section 6.16, 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 CBI Shares outstanding immediately before the Effective Time shall be converted into the right to receive IBG Shares, as calculated and subject to adjustment as set forth in this Section 1.05 and Section 9.01(K) (the “Aggregate Merger Consideration”).

A. Any CBI Shares that are owned by CBI (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 CBI Share issued and outstanding immediately before the Effective Time (excluding CBI Shares canceled pursuant to Section 1.05(A) or held by a Dissenting Shareholder) shall be converted into, and shall be canceled in exchange for, the right to receive a fraction of an IBG Share, rounded to the nearest ten thousandth, equal to the quotient of (a) the quotient of (i) the Shareholder Value, divided by (ii) number of CBI Shares issued and outstanding immediately before the Effective Time, divided by (b) the Average Closing Price (the “CBI Share Exchange Ratio”).

“Shareholder Value” shall mean the difference between (i) the Deal Value, less (ii) the Aggregate Option Holder Payment (as defined in Section 1.13(B)(2)).

“Deal Value” shall mean the product of the (i) Gross Share Number, multiplied by (ii) the Average Closing Price.

“Gross Share Number” shall mean the quotient of (i) $434,000,000, divided by (i) $47.40.

“Average Closing Price” shall mean the average of the daily volume-weighted average sales price per IBG Share on the NASDAQ Stock Market, Inc. Global Select Market System (the “NASDAQ”), for the twenty consecutive trading days ending on and including the third trading day preceding the Closing Date, as reported by Bloomberg.

1. 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 less than $200,000,000, then the $434,000,000 figure used to calculate the Gross Share Number in Section 1.05(B) above shall be reduced by an amount equal to the difference between (i) $200,000,000, minus (ii) the Tangible Equity on the Calculation Date.

C. Subject only to dissenter’s rights under Subchapter H of Chapter 10 of the TBOC at the Effective Time, all CBI 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 CBI Shares (a “CBI 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 CBI Shares will be exchanged for the Merger Consideration upon the surrender of Certificates in accordance with Section 2.05, without interest thereon.

D. In connection with the Merger, CBI may distribute to its shareholders a total of up to $55,250,000 (the “Maximum Distribution Amount”) prior to the Effective Time, a portion of which may be in the form of a return of capital distribution to its shareholders during

the fourth quarter of 2016 (the “Return of Capital Distribution”). In addition, if the Tangible Equity on the Calculation Date is greater than $200,000,000, then CBI may make an additional distribution to its shareholders on the day prior to the Closing Date in an amount equal to the lesser of (i) the difference between (x) the Maximum Distribution Amount, minus (y) the aggregate amount of the Return of Capital Distribution, or (ii) the difference between (x) the actual amount of Tangible Equity on the Calculation Date, less (y) $200,000,000. For clarification, the amount that CBI may distribute to its shareholders prior to the Effective Time may not exceed $55,250,000 regardless of the amount of Tangible Equity on the Calculation Date. Notwithstanding the foregoing, in the event that the Closing Date has not occurred on or prior to June 30, 2017, the Maximum Distribution Amount shall be increased by an amount equal to the consolidated net income of CBI, calculated in accordance with GAAP, for the period commencing on June 1, 2017 and continuing through the Calculation Date. The aggregate amount distributed by CBI to the CBI Shareholders pursuant to this Section 1.05(D) is referred to as the “Section 1.05(D) Distribution Amount.”

E. For purposes of this Agreement, “Tangible Equity” means the tangible shareholders’ equity of CBI as determined from CBI’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 CBI and any CBI Subsidiary 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 CBI and any CBI Subsidiary, including their respective data processing and other IT contracts, all as set forth on Confidential Schedule 1.05(E)(2);

3. All payments owed under the Employment Contracts (as defined in Section 3.20, and all other payments, if any, made to directors, officers and employees related to the consummation of the Merger; and

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

5. The portion of the payroll and income tax owed by CBI resulting from the cashout on a “net settlement” basis, of the Options as provided for in Section 1.13.

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

CBI 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, CBI and IBG shall meet to resolve any such disagreement. If CBI and IBG cannot resolve any such disagreement, then an independent accounting firm mutually agreed to by IBG and CBI shall resolve any such disagreement which resolution shall be final and binding upon CBI and IBG. Confidential Schedule 1.05(E) sets forth the method of calculation and, by way of example only, a preliminary estimate of Tangible Equity.

F. 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 CBI Shares otherwise entitled to receive such fractional share an amount of cash determined by multiplying (i) the Average 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.

Section 1.06. 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 1.07. Dissenting Shareholders. Notwithstanding anything in this Agreement to the contrary, CBI Shares that are held by shareholders of CBI 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 CBI fails to perfect, withdraws or otherwise loses any such right or remedy granted by the Subchapter H of Chapter 10 of the TBOC, each CBI Share held by such shareholder shall be converted into and represent only the right to receive the consideration as specified in Section 1.05.

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 CBI Shareholders pursuant to Section 1.05 (including the Proxy Statement for the shareholder meetings of IBG and CBI and prospectus and other proxy solicitation materials constituting a part thereof (together, the “Proxy Statement”) and all related documents). CBI shall prepare and furnish to IBG such information relating to CBI 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 CBI, 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 CBI and its legal, financial and accounting advisors to the Registration Statement, all amendments and supplements thereto and all responses to requests for additional information. CBI 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 CBI 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 1.08(A) and Section 5.02, IBG shall file, or cause to be filed, the Registration

Statement with the SEC on or before January 16, 2017. 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 CBI (the “CBI Board”) shall duly call, give notice of, and cause to be held, a meeting of its shareholders (the “CBI Meeting”) and will direct that this Agreement and the transactions contemplated hereby be submitted to a vote at the CBI Meeting. Specifically, the CBI Board will present for the consideration of CBI shareholders a proposal to approve and adopt this Agreement and the Merger and the transactions contemplated hereby. The CBI Board will (i) cause proper notice of the CBI Meeting to be given to the CBI shareholders in compliance with applicable law and regulations, (ii) distribute to the CBI shareholders the Proxy Statement, (iii) recommend by the affirmative vote of the CBI Board a vote in favor of approval of the proposals set forth in this Section 1.08(B), subject to Section 1.08(C), and (iv) perform such other acts as may reasonably necessary to ensure that shareholder approval of the proposals set forth in this Section 1.08(B) are obtained. CBI 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, CBI and the CBI Board are permitted to change its recommendation as contemplated by this Section 1.08(C) (“Change in Recommendation”) if and only to the extent that:

1. CBI, the CBI Subsidiaries and the CBI Representatives (as defined in Section 5.10), have complied in all material respects with Section 5.10;

2. the CBI Board, after consultation with its outside counsel, has determined in good faith that failure to make a Change in Recommendation would reasonably be expected to result in a violation of its fiduciary duties under applicable law; and

3. if the CBI Board intends to make a Change in Recommendation after CBI has received an Acquisition Proposal (as defined in Section 5.10(D)), (a) the CBI Board has concluded in good faith, after giving effect to all of the adjustments which may be offered by IBG pursuant to subclause (c) below, that such Acquisition Proposal constitutes a Superior Proposal (as defined in Section 5.10(E)), (b) CBI shall notify IBG, at least five business days in advance, of its intention to make a Change in Recommendation in response to such Superior Proposal (including the identity of the party making such Acquisition Proposal) and furnish to IBG a written description of the material terms of the Superior Proposal and copies of such other material documents that CBI is not required to keep confidential, and (c) before making such a Change in Recommendation, CBI shall, and shall cause its financial and legal advisors to, during the period after CBI’s delivery of the notice referred to in subclause (b) above, negotiate with IBG in good faith for a period of up to five business days (to the extent IBG desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal.

D. The Board of Directors of IBG (the “IBG Board”) shall duly call, give notice of, and cause to be held, a meeting of its shareholders (the “IBG Meeting”) and will direct that this Agreement and the transactions contemplated hereby be submitted to a vote at the IBG Meeting.

The IBG Board will (i) cause proper notice of the IBG Meeting to be given to the IBG shareholders in compliance with applicable law and regulations, (ii) distribute to the IBG shareholders the Proxy Statement, (iii) recommend by the affirmative vote of the IBG Board a vote in favor of approval of the proposals set forth in this Section 1.08(D), and (iv) perform such other acts as may reasonably be necessary to ensure that shareholder approval of the proposals set forth in this Section 1.08(D) are obtained. IBG 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.

Section 1.09. Effective Time. The “Effective Time” means the effective time of the Merger as specified in the Certificate of Merger filed with and certified by the Texas Secretary of State (“TSOS”). The Certificate of Merger shall be filed with the TSOS on the Closing Date.

Section 1.10. Bank Merger. Immediately after the Effective Time, IBG shall cause the Bank Merger to be consummated.

Section 1.11. Anti-Dilution Provisions. If, between the date of this Agreement and the Effective Time, the IBG Shares are changed into a different number or class of shares by reason of any reclassification, recapitalization, split-up, combination, exchange of shares or readjustment, or a share dividend thereon is declared with a record date within said period, the CBI Share Exchange Ratio and any dependent items shall be adjusted accordingly to provide to the CBI Shareholders the same economic effect as contemplated by this Agreement prior to such action; but an offering or sale of IBG Shares shall not be deemed a reclassification, recapitalization, split-up, combination, exchange of shares or readjustment of the IBG Shares.

A. None of IBG, Independent Bank, CBI or Northstar Bank has taken or agreed to take any action, or is aware of any fact or circumstance, that would prevent the Merger from qualifying as a reorganization within the meaning of § 368 of the Code. IBG, Independent Bank, CBI and Northstar Bank shall each use commercially reasonable efforts to cause (i) the Merger to qualify as a “reorganization” within the meaning of §368(a) of the Code, and (ii) each of IBG and CBI to be a party to the reorganization within the meaning of §368(b) of the Code. Each of IBG, Independent Bank, CBI and Northstar Bank agrees to file all of its tax returns, including complying with the filing requirements of Treasury Regulations §1.368-3, consistent with the treatment of the Merger as a “reorganization” within the meaning of §368(a) of the

Code and in particular as a transaction described in §368(a)(1)(A) of the Code and Treasury Regulations §1.368-2(b)(1)(ii). This Agreement is intended to constitute a “plan of reorganization” within the meaning of Treasury Regulations §1.368-2(g).

B. None of IBG, Independent Bank, CBI or Northstar Bank has taken or agreed to take any action, or is aware of any fact or circumstance, that would prevent the Bank Merger from qualifying as a reorganization within the meaning of §368 of the Code. IBG, Independent Bank, CBI and Northstar Bank shall each use commercially reasonable efforts to cause (i) the Bank Merger to qualify as a “reorganization” within the meaning of §368(a) of the Code, and (ii) each of Independent Bank and Northstar Bank to be a party to the reorganization within the meaning of §368(b) of the Code. Each of IBG, Independent Bank, CBI and Northstar Bank agrees to file all of its tax returns, including complying with the filing requirements of Treasury Regulations §1.368-3, consistent with the treatment of the Bank Merger as a “reorganization” within the meaning of §368(a) of the Code and in particular as a transaction described in §368(a)(1)(A) of the Code and Treasury Regulations §1.368-2(b)(1)(ii). This Agreement is intended to constitute a “plan of reorganization” within the meaning of Treasury Regulations §1.368-2(g).

C. IBG shall deliver to Andrews Kurth LLP and Fenimore, Kay, Harrison & Ford LLP a “Tax Representation Letter,” dated as of the Closing Date and signed by an officer of IBG, containing representations of IBG, and CBI shall deliver to Andrews Kurth LLP and Fenimore, Kay, Harrison & Ford LLP a “Tax Representation Letter,” dated as of the Closing Date and signed by an officer of CBI, containing representations of CBI, in each case as shall be reasonably necessary or appropriate to enable Andrews Kurth LLP to render the tax opinion described in Section 8.14 and to enable Fenimore, Kay, Harrison & Ford LLP to render the tax opinion described in Section 7.11.

D. IBG and Independent Bank shall comply with the recordkeeping and information reporting requirements set forth in Treasury Regulations § 1.368-3.

E. Following the Merger and the Bank Merger, neither IBG nor Independent Bank (or any successor thereof) will take any action or fail to take any action that would prevent the Merger or Bank Merger from satisfying the “continuity of business enterprise” requirement for a “reorganization” as provided in Treasury Regulations § 1.368-(d).

Section 1.13. Treatment of Awards. Pursuant to the Carlile Bancshares, Inc. Amended and Restated 2015 Equity Incentive Plan (the “CBI Award Plan”), CBI has granted (i) options to purchase shares of CBI common stock which are outstanding and unexercised (the “Options”), and (ii) restricted shares of CBI common stock which are restricted and subject to forfeiture (the “Restricted Shares”). CBI and IBG shall take the following actions with respect to the Options and the Restricted Shares.

A. Vesting. Pursuant to Section 12 of the CBI Award Plan, the Administrator (as defined in the CBI Award Plan) shall unilaterally provide for the full vesting of all unvested Options and the release of the Restricted Shares from forfeiture and transfer restrictions effective as of the Calculation Date.

B. Options. The Administrator shall effectuate the automatic cashout and termination of the Options on the following basis:

1. Each holder of an Option (an “Option Holder”) shall be entitled to receive, for each share of CBI common stock underlying their respective Option (an “Option Share”), an amount equal to the difference between (i) the Closing Date Fair Market Value, minus (ii) the applicable Option Share exercise price as set forth on Confidential Schedule 3.03(C) (the “Per Option Share Price”). For purposes of this Agreement, the “Closing Date Fair Market Value” shall mean the quotient of (x) the sum of (1) the aggregate number of shares of IBG Shares to be issued pursuant to Section 1.05(B) (as may be adjusted pursuant to Section 1.05(B)(1) and Section 9.01(K) but without giving effect to the clause “less the Aggregate Option Holder Payment (as defined in 1.13(B)(2) below)” contained in Section 1.05(B)), multiplied by the Average Closing Price, plus (2) an amount equal to the portion of the Section 1.05(D) Distribution that is not a Return of Capital Distribution, plus (3) the aggregate exercise price to be paid to exercise the Options as set forth on Confidential Schedule 3.03(C), divided by (y) the number of CBI Shares issued and outstanding immediately before the Effective Time, plus the number of Option Shares outstanding and unexercised as of such date.

2. Within five (5) business days following the Closing Date, IBG shall pay to each 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 Option Holder (the “Option Holder Payment”). The aggregate Option Holder Payment paid to all of the Option Holders is referred to as the “Aggregate Option Holder Payment.”

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

4. In connection with the cashout of the Options and prior to Closing, CBI shall use commercially reasonable efforts to obtain a written acknowledgement signed by each Option Holder stating that their Option will be cancelled in exchange for the Option Holder Payment and that they will have no further right to purchase CBI Shares or any other right with respect to their Options.

Section 2.01. Time and Place of the Closing and Closing Date. The transactions contemplated under this Agreement shall be consummated on a date (the “Closing Date”) mutually agreeable to IBG and CBI that is within forty-five (45) days after the receipt of all necessary regulatory, corporate and other approvals, and the expiration of all associated mandatory waiting periods (the “Required Approvals”). On the Closing Date, a meeting (the “Closing”) will take place at which the parties to this Agreement will exchange certificates, letters and other documents in order to determine whether all of the conditions set forth in ARTICLE VII and ARTICLE VIII have been satisfied or waived or whether any condition exists that would permit a party to this Agreement to terminate this Agreement. If no such condition then exists or if no party elects to exercise any right it may have to terminate this Agreement, then and thereupon the appropriate parties shall execute such documents and instruments as may be necessary or appropriate in order to effect the transactions contemplated by this Agreement.

The Closing shall take place at 10:00 a.m., local time at the executive offices of IBG on the Closing Date, or at such other time and place to which IBG and CBI may agree.

A certificate, dated as of the Closing Date, duly executed by the Secretary of Independent Bank, acting solely in her capacity as an officer of Independent Bank, pursuant to which Independent Bank shall certify (i) the due adoption by the Board of Directors of Independent Bank (the “Independent Bank Board”) of corporate resolutions attached to such certificate authorizing the execution and delivery of the Bank Merger Agreement and any other agreements and documents contemplated hereby and thereby, and the consummation of the transactions contemplated hereby and thereby, including the Bank Merger; (ii) the approval by IBG as the sole shareholder of Independent Bank of the Bank Merger Agreement, and the consummation of the transactions contemplated hereby and thereby, including the Bank Merger; and (iii) the incumbency and true signatures of those officers of Independent Bank duly authorized to act on its behalf in connection with the execution and delivery of the Bank Merger Agreement and any other agreements and documents contemplated hereby and thereby, and the consummation of the transactions contemplated hereby and thereby, on behalf of Independent Bank;

G. All other documents required to be delivered to CBI by IBG under the provisions of this Agreement and all other documents, certificates and instruments as are consistent with the terms of this Agreement and reasonably requested by CBI or its counsel.

A. On the business day before the Closing Date, IBG shall deposit or cause to be deposited in trust with Wells Fargo Bank, N.A. (the “Exchange Agent”) certificates for shares or evidence of shares in book entry form representing the aggregate number of IBG Shares which the holders of CBI 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 CBI 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 CBI 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) a number of IBG Shares equal to the product of (x) the CBI Share Exchange Ratio, multiplied by (y) the number of CBI 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(F), and such Certificate shall forthwith be canceled. The consideration to be received by a CBI Shareholder upon surrender of his Certificate is referred to as the “Merger Consideration.” Until surrendered in accordance with this Section 2.05, each Certificate (other than Certificates representing CBI 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 CBI shall be closed and there shall be no transfers on the share transfer books of CBI of the CBI 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 2.05.

D. Former shareholders of CBI shall be entitled to vote after the Effective Time at any meeting of IBG’s shareholders the number of IBG Shares into which their shares are converted, regardless of whether such shareholders of CBI 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 2.05. After the surrender of a Certificate in accordance with this Section 2.05,

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 CBI for six months after the Exchange Agent mails the letter of transmittal pursuant to this Section 2.05 shall be delivered to IBG upon demand, and any shareholders of CBI who have not theretofore complied with the exchange procedures in this Section 2.05 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 CBI 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, CBI, the Exchange Agent or any other person shall be liable to any former holder of CBI 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 CBI 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.

Each material Property of CBI and each CBI Subsidiary is insured for the benefit of CBI and such CBI Subsidiary in amounts deemed adequate by CBI’s and each CBI Subsidiary’s respective management against risks customarily insured against. Except as set forth in Confidential Schedule 3.15, there have been no claims under any fidelity bonds of CBI or any CBI Subsidiary since June 30, 2013 and to the Best Knowledge of CBI, there are no facts that would reasonably be expected to form the basis of a claim under such bonds.

Except as disclosed on Confidential Schedule 3.18 neither CBI nor any CBI Subsidiary uses any asset owned by any shareholder or any present or former director or officer of CBI or any CBI Subsidiary, or any Affiliate thereof, in the operations (other than personal belongings of such officers and directors located in the Northstar Bank’s premises, the removal of which would not result in a Material Adverse Change), nor do any of such persons own or have the right to use real property that is adjacent to property on which Northstar Bank’s facilities are located.

With respect to any loan or other evidence of indebtedness all or a portion of which has been sold to or guaranteed by any governmental authority, including the Small Business Administration, each of such loans was made in compliance and conformity with all relevant laws, rules, regulations and procedures such that such governmental authority’s guaranty of such loan is effective during the term of such loan in all material respects.

The use that CBI or any CBI Subsidiary makes of the Properties will not result in the use, generation, storage, transportation, accumulation, disposal or release of any Hazardous Material on, in or from any of the Properties, except as would not be expected to have or cause a Material Adverse Change.

D. There is no action, suit, proceeding, investigation, or inquiry before any Governmental Authority pending or, to the Best Knowledge of CBI, threatened, against CBI or any CBI Subsidiary relating in any way to any Environmental Law.

There are no pending or, to the Best Knowledge of CBI, threatened investigations by any Regulatory Agency that would reasonably result in a Regulatory Agreement with respect to CBI or any CBI Subsidiary.

B. Since January 1, 2014, all reports, records, registrations, statements, notices and other documents or information required to be filed by CBI or any CBI Subsidiary with any Regulatory Agency have been duly and timely filed and, to the Best Knowledge of CBI, all information and data contained in such reports, records or other documents are true, accurate, correct and complete in all material respects.

CBI has made and will make available to IBG copies of all of CBI’s and any CBI Subsidiary’s standard forms of notes, mortgages, deeds of trust and other routine documents of a like nature used on a regular and recurring basis in the ordinary course of their respective business.

Section 3.27. Fiduciary Responsibilities. Each of CBI and each CBI Subsidiary 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.

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

A. Set forth on Confidential Schedule 3.29 is a complete and correct list of all “employee benefit plans” (as defined in ERISA), all specified fringe benefit plans as defined in Code § 6039D, 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), and any trust, escrow or other agreement related thereto, which (a) is currently maintained or contributed to by CBI or any CBI Subsidiary, or with respect to which CBI or any CBI Subsidiary has any liability, and (b) provides benefits to any officer, employee, service provider, former officer or former employee of CBI or any CBI 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. CBI 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, CBI or any CBI 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. 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. 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 CBI, none are threatened. No written or, to the Best Knowledge of CBI, oral representations have been made by CBI or any CBI Subsidiary to any employee or former employee of CBI or any CBI 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 CBI, any CBI 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. 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 six (6) years, by any trade or business with which CBI or any CBI Subsidiary is required by any of the rules contained in the Code or ERISA to be treated as a single employer (“Controlled Group Plans”):

1. All Controlled Group Plans which are “group health plans” (as defined in the Code and ERISA) have been operated before 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 Code § § 4980B and 4980D would not reasonably be expected to subject CBI or any CBI Subsidiary to material liability;

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

3. 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 audited 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.

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 Code §280G(b)(1)) solely as a result of the transactions contemplated by this Agreement; and no such person is entitled to receive any additional payment from CBI, any CBI Subsidiary, or IBG if the excise tax of Code §4999(a) is imposed on such person.

Section 3.32. Data Processing Agreements. Northstar 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 Confidential 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, neither CBI nor Northstar Bank has any agreement with any other person or entity for data processing, ATM or other technology services.

Section 3.33. Dissenting Shareholders. To the Best Knowledge of CBI, there is no plan or intention on the part of any shareholders of CBI to exercise their appraisal rights in the manner provided by applicable law.

Section 3.34. Fair Housing Act, Home Mortgage Disclosure Act and Equal Credit Opportunity Act and Flood Disaster Protection Act. Northstar 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.), the Equal Credit Opportunity Act (15 U.S.C. §1691 et seq.), and the Flood Disaster Protection Act (42 USC §4002, et seq.), and all regulations promulgated thereunder. Since June 30, 2011, CBI 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 Northstar Bank there is no, threatened administrative inquiry, proceeding or investigation with respect to its compliance with such laws.

Section 3.35. Usury Laws and Other Consumer Compliance Laws. All loans of Northstar Bank have been made in compliance in all material respects with all applicable statutes and regulatory requirements at the time of such loan or any renewal thereof, including the Texas

Rev. Civ. Stat. Ann. Art. 5062-2.01, et seq.) and all statutes governing the operation of banks operating in the State of Texas. Each such loan was made by Northstar Bank in the ordinary course of its lending business.

Section 3.36. Zoning and Related Laws. Except as disclosed on Confidential Schedule 3.36, all real property owned or operated by Northstar Bank and the use thereof is in compliance with all applicable laws, ordinances, regulations, orders or requirements, including building, zoning and other laws, except where the failure, whether individually or in the aggregate, to be so in compliance would not reasonably be expected to cause a Material Adverse Change.

Section 3.37. Business Combination. This Agreement and the transactions contemplated hereby are exempt from the requirements of Subchapter M of Chapter 21 of the TBOC and any other applicable state takeover law or state law that purports to limit or restrict business combinations or the ability to acquire or vote shares.

Section 3.38. Fairness Opinion. Before the execution of this Agreement, CBI has received an oral opinion from Sandler O’Neil & Partners, L.P., which will be followed by a written opinion, to the effect that, subject to the terms, conditions and qualifications set forth therein, as of the date thereof, the Aggregate Merger Consideration to be received by the CBI Shareholders pursuant to this Agreement is fair to such shareholders from a financial point of view. As of the date of this Agreement, such opinion has not been amended or rescinded.

Section 3.40. Derivative Contracts. Neither CBI nor any CBI Subsidiary is a party to nor has it agreed to enter into an exchange traded or over-the-counter swap, forward, future, option, cap, floor or collar financial contract or agreement, or any other contract or agreement not included in the Financial Statements which is a financial derivative contract (including various combinations thereof).

Section 3.41. Internal Controls. CBI and each CBI Subsidiary maintains an adequate system of internal accounting controls that provide assurance that (a) transactions are executed with management’s authorization; (b) transactions are recorded as necessary to permit preparation of the consolidated financial statements of CBI and to maintain accountability for CBI’s consolidated assets; (c) access to CBI’s assets is permitted only in accordance with management’s authorization; (d) the reporting of CBI’s assets is compared with existing assets at regular intervals; and (e) extensions of credit and other receivables are recorded accurately, and proper and adequate procedures are implemented to effect the collection thereof on a current and timely basis. Neither CBI’s nor any CBI Subsidiary’s systems, controls, data or information are recorded, stored, maintained, operated or otherwise wholly or partly dependent on or held by any means (including any electronic, mechanical or photographic process, whether computerized or not) which (including all means of access thereto and therefrom) are not under the exclusive ownership and direct control of CBI, the CBI Subsidiaries or their accountants and consultants, except as would not reasonably be expected to have a materially adverse effect on the system of internal accounting controls described in the preceding sentence.

Section 3.42. Indemnification. Except as set forth on Confidential Schedule 3.42, to the knowledge of CBI, no action or failure to take action by any present or former director, officer, employee or agent of CBI or any CBI Subsidiary has occurred which would give rise to a material claim by any such individual for indemnification from CBI or any CBI Subsidiary.

Section 3.43. Organization and Qualification of the Trusts. CBI has two special purpose trust subsidiaries, Northstar Statutory Trust II and Northstar Statutory Trust III (collectively, the “Trusts”). With respect to the Trusts:

A. The Trusts have issued and sold capital securities (the “Capital Securities”) and common securities (the “Common Securities”) under an Amended and Restated Declaration of Trust (the “Trust Agreement”), and CBI has issued to the Trusts, Floating Rate or Fixed/Floating Rate Junior Subordinated Deferrable Interest Debentures (“Debentures”), under an Indenture (the Trust’s Indenture and Trust Agreement are collectively referred to as its “Operative Documents”). Confidential Schedule 3.43 sets forth, with respect to the Trusts, the (i) dates of the respective Trust Agreements and Indentures, (ii) aggregate liquidation value of the respective Capital Securities, (iii) aggregate liquidation value of the respective Common Securities, (iv) aggregate amount of Debentures that have been issued to each Trust by CBI, (v) the rate paid on the respective Capital Securities, the Common Securities and the Debentures (collectively, the “Securities”), (vi) the dates after which CBI may redeem the respective Debentures at par, and (vii) the maturity date of the respective Debentures.

B. The Trusts have been duly created and each is validly existing in good standing as a statutory trust under the laws of the State of Delaware with the power and authority to own property and to conduct the business it transacts and proposes to transact and to enter into and perform its obligations under the Operative Documents. Each Trust is not a party to or otherwise bound by any material agreement other than the Operative Documents and a Placement Agreement of even date with the Trust Agreement. Each Trust is and will, be classified for tax purposes as a grantor trust and not as an association taxable as a corporation.

C. The Capital Securities and the Common Securities have been duly authorized by the respective Trust Agreements, have been validly issued and represent undivided beneficial interests in the assets of the respective Trusts. None of the Capital Securities or the Common Securities is subject to preemptive or other similar rights. All of the outstanding Common Securities are directly owned by CBI free and clear of any pledge, security interest, claim, lien or other encumbrance, and have been issued in compliance with applicable federal and state securities laws. The Common Securities satisfy the eligibility requirements of Rule 144A(d)(3) issued under the Securities Act of 1933, as amended. Neither CBI nor any Trust is an “investment company” or an entity “controlled” by an “investment company,” in each case within the meaning of Section 3(a) of the Investment Company Act of 1940, as amended, without regard to Section 3(c) of that act. The Debentures are not held of record by shareholders of CBI or any CBI Subsidiary.

D. The sole assets of each Trust are its Debentures, any interest paid on such Debentures to the extent not distributed, proceeds of such Debentures, or any of the foregoing.

E. All of the proceeds from the sale of the Capital Securities issued by each Trust have been invested in its respective Debentures. All of the proceeds from the sale of the Common Securities issued by each Trust have been invested in the respective Debentures. All Debentures are and have been held by each Trust since their initial issuance.

F. Neither Trust was not formed to, and is not authorized to, conduct any trade or business and neither Trust has conducted any trade or business since it was formed. The Trusts exist for the exclusive purposes of (i) issuing and selling its respective Capital Securities and Common Securities, (ii) using the proceeds from the sale of its respective Capital Securities and Common Securities to acquire its respective Debentures, and (iii) engaging only in activities necessary, advisable or incidental thereto. Each Trust was formed to facilitate direct investment in the assets of such Trust, and the existence of multiple classes of ownership is incidental to that purpose. There is no intent to provide holders of such interests in each Trust with diverse interests in the assets of each Trust.

G. CBI has not exercised its right to defer interest payments on the Debentures.

H. Each Trust’s income consists solely of payments made by CBI with respect to the respective Debentures, and such payments are not derived from the active conduct of a financial business by such Trust. Both CBI’s obligation to make those payments and the amounts thereof are set forth in the respective Debentures. Neither CBI’s obligation to make those payments nor the amounts payable by CBI is dependent on income or profits of CBI or any Affiliate of CBI (although CBI’s ability to do so is so dependent).

I. CBI has not issued any class of capital shares either pari passu or senior to the Debentures. All Debentures are either pari passu or senior to CBI’s trade accounts payable arising in the ordinary course of business.

J. CBI and the Trusts have created a debtor-creditor relationship between CBI, as debtor, and each Trust, as a creditor, and CBI and the Trusts have treated the Debentures as indebtedness for all tax purposes.

Section 3.44. Representations Not Misleading. No representation or warranty by CBI contained in this Agreement contains or will contain on the Closing Date any untrue statement of a material fact or omits or will omit on the Closing Date to state a material fact necessary to make the statements contained herein, in light of the circumstances under which they were made, not misleading. To the Best Knowledge of CBI, all written statements, exhibits, schedules, and other documents furnished to IBG by CBI or any CBI Subsidiary as part of the due diligence for this Agreement are accurate in all material respects.

IBG hereby makes the following representations and warranties to CBI, as qualified, if necessary, by the Confidential Schedules referenced herein. The disclosure of a matter on any Confidential Schedule shall constitute disclosure for purposes of all Confidential Schedules required by this Agreement.

A. IBG is a bank holding company registered under the Bank Holding Company Act of 1956, as amended. IBG is a corporation duly organized, validly existing and in good standing under all laws, rules and regulations of the State of Texas. IBG and Independent Bank each has all requisite corporate power and authority to own each respective IBG Subsidiary as now owned, and to enter into and carry out its obligations under this Agreement and the other agreements contemplated hereby to which IBG is a party.

Notwithstanding anything to the contrary contained in this Section 5.10, if at any time after the date hereof and before the Closing, CBI and the CBI Representatives, having each theretofore complied with the terms of Section 5.10(A), receives a bona fide, unsolicited written Acquisition Proposal, CBI and the CBI 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 CBI 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 CBI Board to furnish such information or access or enter into such discussions or negotiations would reasonably be expected to be a violation of its fiduciary duties to the CBI shareholders; but before furnishing any material nonpublic information, CBI 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 Mutual Confidentiality and Nondisclosure Agreement entered into with IBG on July 22, 2016, which confidentiality agreement shall not prohibit CBI from complying with the terms of this Section 5.10. CBI 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 CBI or for access to the Properties, books or records of CBI by any person that has made, or to the Best Knowledge of CBI 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. CBI 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 CBI or the CBI Board from (i) taking the actions provided in Sections 1.08(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 CBI’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 CBI Share regarding any of the following (other than the transactions contemplated by this Agreement) involving CBI: (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, CBI, 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 CBI 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 CBI 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 CBI’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. CBI shall use commercially reasonable efforts to obtain all consents and approvals from third parties listed on Confidential Schedule 3.05. CBI 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 CBI 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 CBI in writing before any Environmental Inspection, and CBI 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 CBI 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 CBI of the Secondary Investigation, and CBI may place reasonable time and place restrictions on the Secondary Investigation.

B. IBG shall make available to CBI the results and reports of such Environmental Inspections and Secondary Investigations promptly after IBG receives or is advised of such results. IBG shall not have any liability or responsibility of any nature whatsoever for the results, conclusions or other findings related to any Environmental Inspection, Secondary Investigation or other environmental survey. If this Agreement is terminated, except as otherwise required by law, reports to any Governmental Authority of the results of any Environmental Inspection, Secondary Investigation or other environmental survey shall not be made by IBG. IBG shall make no such report before Closing unless required to do so by applicable law, and in such case will give CBI reasonable written notice of IBG’s intentions.

C. IBG shall have the right to terminate this Agreement by providing written notice to CBI 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 or potential material violations of Environmental Laws; (iii) CBI 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 or potentially could reasonably be expected to require a remedial or cleanup action costing in excess of $250,000 or result in a Material Adverse Change to CBI or any CBI 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 could reasonably be expected to result in a Material Adverse Change. IBG shall advise CBI in writing (the “Environmental Notice”) as to whether IBG intends to terminate this Agreement because IBG disapproves of the results of the Environmental Inspection or Secondary Inspection in respect of the Properties. Upon receipt of the Environmental Notice, CBI 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. If CBI fails to demonstrate correction of the violations or conditions to the reasonable satisfaction of IBG, IBG may terminate the Agreement on the 31st day after the date of the Environmental Notice.

D. CBI agrees to make available to IBG and its consultants, agents and representatives all documents and other material relating to environmental conditions of any Property including the results of other environmental inspections and surveys. CBI also agrees that all engineers and consultants who prepared or furnished such reports may discuss such reports and information with IBG and shall be entitled to certify the same in favor of IBG and its consultants, agents and representatives and make all other data available to IBG and its consultants, agents and representatives.

Section 5.13. Employee Plans and Employee Contracts. Before the Closing Date, CBI shall and shall cause each CBI 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, CBI and each CBI 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 a release with respect to their agreement (the “Employment Contract Release”).

Section 5.14. Confidential Schedules. At least three business days before the Closing, CBI agrees to provide IBG with supplemental Confidential Schedules to be delivered by CBI pursuant to this Agreement reflecting any material changes thereto between the date of this Agreement and the Closing Date. Any such supplemental Confidential Schedules shall be deemed to modify the representations and warranties of CBI for purposes of determining whether there has been a breach of any representation or warranty of CBI in Article III hereof; provided, however, that such supplemental Confidential Schedules shall not modify the representations and warranties of CBI for purposes of determining whether there has been a breach of the representations and warranties of CBI pursuant to Section 8.01 of this Agreement.

Section 5.15. Voting and Lock Up Agreement. CBI shall execute and deliver, and shall use commercially reasonable efforts to cause each person or entity listed on Confidential Schedule 5.15 to execute and deliver contemporaneously with the execution of this Agreement, a Voting and Lock Up Agreement. CBI acknowledges that, upon the execution and delivery of the Voting and Lock Up Agreements, such persons or entities shall have agreed that they will vote the CBI Shares owned by them in favor of this Agreement and the transactions contemplated hereby, including the Merger, subject to required regulatory approvals for the transactions contemplated by this Agreement.

Section 5.16. Releases. CBI shall use its commercially reasonable efforts to obtain from each of the directors and executive officers of CBI and each CBI Subsidiary listed on Confidential Schedule 5.16 a written release in the form attached hereto as Exhibit “A” executed by such director or executive officer and dated the Closing Date, releasing CBI and each CBI Subsidiary from claims arising before the Effective Time (the “Releases by D&Os”).

Section 5.17. Other Agreements. CBI shall, and shall cause each CBI Subsidiary to, execute and deliver the Bank Merger Agreement and such other agreements, certificates of merger, certificates, and other documents reasonably necessary to effect the Merger and the Bank Merger, and to take all actions reasonably necessary or required to consummate the transactions contemplated thereby in accordance with the terms hereof.

Section 5.18. Support Agreement. CBI shall use commercially reasonable efforts to cause each outside director of CBI and Northstar Bank to execute and deliver to IBG, contemporaneously with the execution of this Agreement, a Director Support Agreement providing for the continuing support of Independent Bank by the outside directors (the “Support Agreements”).

Section 5.19. Shareholder Lists. After the date of this Agreement, CBI shall from time to time make available to IBG, upon its request, a list of the CBI Shareholders, a list showing all transfers of the CBI Shares, a list showing the grant and exercise of Options, and such other information as IBG may reasonably request regarding both the ownership and prior transfers of the CBI Shares and Options. Specifically, CBI shall deliver to IBG a certified list of CBI Shareholders, in form and content reasonably satisfactory to the Exchange Agent, at least ten days prior to the Closing Date.

Section 5.20. Conforming Accounting Adjustments. CBI shall, if requested in writing by IBG, consistent with GAAP, RAP and applicable banking laws and regulations, immediately before Closing, make such accounting entries as CBI may reasonably request in order to conform the accounting records of CBI to the accounting policies and practices of IBG. No such adjustment by CBI or any CBI Subsidiary shall of itself constitute or be deemed to be a breach, violation or failure by CBI or any CBI Subsidiary to satisfy any representation, warranty, covenant, condition or other provision of this Agreement or constitute grounds for termination of this Agreement by IBG or be an acknowledgment by CBI of any adverse circumstances for purposes of determining whether the conditions to IBG’s obligations under this Agreement have been satisfied, nor will any such adjustment affect the calculation of the Tangible Equity under Section 1.05. The recording of any such adjustments shall not be deemed to imply any misstatement of previously furnished financial statements or information and shall not be construed as concurrence by CBI, any CBI Subsidiary or their respective management with any such adjustments.

Section 5.21. D & O Liability Insurance. Contemporaneously with the Closing, CBI shall purchase an extended reporting period for four (4) years under CBI’s existing directors and officers liability insurance policy for purposes of covering actions occurring prior to the Effective Time, on terms approved by IBG. Notwithstanding any other provision of this Agreement, the cost of the premiums for such coverage shall be paid by CBI and shall be included (as a deduction) in the calculation of Tangible Equity.

Section 5.22. Termination of DP Contracts and IT Conversion. CBI will use commercially reasonable efforts, including but not limited to notifying appropriate parties and negotiation in good faith a reasonable settlement, to ensure that the DP Contracts and contracts related to the provision of any other electronic banking services, if the Merger occurs, be terminated after the consummation of the Merger on a date to be mutually agreed upon by IBG and CBI. Such notice and actions by CBI will be in accordance with the terms of such contracts. CBI shall use reasonable efforts and cooperate with IBG to facilitate a smooth conversion of data processing, item processing, network and related hardware and software, telephone systems, telecommunications, data communications and other technologies, including participating in conversion planning, design, mapping and testing activities before the Closing Date.

Section 5.23. Employment Agreements. CBI shall use commercially reasonable efforts to cause the executive officers identified in Confidential Schedule 5.23 to execute and deliver to IBG, contemporaneously with the execution of this Agreement, an employment agreement providing for their continued employment with Independent Bank following the Merger.

Section 5.24. Obligations Related to Trust Preferred Securities. CBI will reasonably cooperate with IBG to permit IBG, upon completion of the Merger to assume expressly the obligations of CBI under the Indentures; but in no event will CBI or its counsel be required to deliver opinions or certificates except as the trustees of the Trusts may reasonably require with respect to the establishment and status of the Trust and CBI’s performance of its obligations before, and not in connection with, the assumption of the obligations by IBG.

Section 5.25. Transaction Litigation. CBI shall give IBG the opportunity to participate in the defense or settlement of any stockholder litigation against CBI and/or its directors relating to the Merger and the other transactions contemplated by this Agreement, and no such settlement shall be agreed to without the prior written consent of IBG, which consent shall not be unreasonably withheld, conditioned or delayed. For purposes of this paragraph, “participate” means that the non-litigating party will be kept apprised of proposed strategy and other significant decisions with respect to the litigation by the litigating party, consistent with the common interest of CBI and IBG in these matters and the applicable privileges and protections provided therein, and the non-litigating party may offer comments or suggestions with respect to the litigation, but will not be afforded any decision making power or other authority over the litigation, except for the settlement consent set forth above.

Section 5.26. Separation Agreements. CIB shall use commercially reasonable efforts to cause the executive officers of CBI identified in Schedule 5.26 to execute and deliver contemporaneously with the execution of this Agreement, a Separation Agreement providing for the separation of their employment with CBI effective as of the Closing Date.

Section 5.27. No Excess Parachute Payments. CBI and each CBI Subsidiary shall not make any payment or provide any benefit to any officer, director or employee of CBI, any CBI Subsidiary, or any of their respective Affiliates who is a “disqualified individual” (as such term is defined in Treasury Regulation § 1.280 G-1) under any employment, severance, or termination agreement, other compensation arrangement or benefit plan currently in effect if such payment or benefit would be an “excess parachute payment” (as such term is defined in Code § 280G (b)(1)) solely as a result of the transactions contemplated by this Agreement or if such payment or benefit would result in the excise tax of Code § 4999 being imposed on any such person.

Section 6.01. Commercially Reasonable Efforts. IBG agrees to use commercially reasonable efforts to cause the consummation of the transactions contemplated hereby in accordance with the terms and conditions of this Agreement.

Section 6.02. Untrue Representations. IBG shall promptly notify CBI in writing if IBG becomes aware of any fact or condition that makes untrue, or shows to have been untrue, in any material respect, any confidential schedule to this Agreement or any representation or warranty made by IBG in ARTICLE IV or that results in IBG’s failure to comply with any covenant, condition or agreement contained in this Agreement.

Section 6.03. Affirmative Covenants. Except as otherwise permitted or required by this Agreement, from the date hereof until the Effective Time, IBG shall and shall cause Independent Bank to:

B. Maintain the general character of its business and conduct its business in its ordinary and usual manner;

IBG further agrees that if it shall become aware before the effectiveness of the Registration Statement of any information furnished by such party that would cause any of the statements in the Registration Statement or the Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform CBI thereof and to take the necessary steps to correct the Registration Statement or the Proxy Statement. IBG agrees to advise CBI, promptly after IBG receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of IBG Shares for offering or sale in any jurisdiction, of the initiation or, to the extent IBG is aware thereof, threat of any proceeding for any such purpose, or of any request by the SEC for the amendment or supplement of the Registration Statement or for additional information. IBG agrees to promptly provide to CBI copies of all correspondence between IBG or any of its representatives, on the one hand, and the SEC, on the other hand.

IBG shall promptly notify CBI in writing of any litigation, or of any claim, controversy or contingent liability that might reasonably be expected to become the subject of litigation, against IBG or Independent Bank or affecting any of their respective Properties, if such litigation or potential litigation is reasonably likely, in the event of an unfavorable outcome, to result in a Material Adverse Change. IBG shall promptly notify CBI in writing of any legal action, suit or proceeding or judicial, administrative or governmental investigation, pending or, to the Best Knowledge of IBG, threatened against IBG or Independent Bank that (i) questions or could reasonably be expected to question the validity of this Agreement or the agreements contemplated hereby or any actions taken or to be taken by IBG with respect hereto or thereto or (ii) seeks to enjoin or otherwise restrain the transactions contemplated hereby or thereby.

Section 6.07. Regulatory and Other Approvals. With the cooperation of CBI, IBG shall use commercially reasonable efforts to prepare all documentation, to effect all filings and to obtain all permits, consents, approvals and authorizations of all third parties and federal or state bank regulatory or Governmental Authority necessary to consummate the Merger and the transactions contemplated by this Agreement, including the applications for the prior approval of the Merger and the Bank Merger by the FRB (or appropriate Federal Reserve Bank acting on delegated authority), the TDB, the FDIC or the Colorado Division of Banking. Provided that CBI has promptly provided information reasonably requested by IBG and its comments to draft applications, and otherwise complied with Section 5.02, such applications shall be filed on or before December 30, 2016. IBG shall use commercially reasonable efforts to obtain all such regulatory approvals and any other approvals from third parties at the earliest practicable time. IBG shall keep CBI reasonably informed as to the status of such applications and filings, and IBG shall promptly furnish CBI and its counsel with copies of all such regulatory filings and all correspondence for which confidential treatment has not been requested.

Section 6.08. Other Agreements. IBG shall, and shall cause Independent Bank to, take such actions and to execute and deliver the Bank Merger Agreement and such other agreements, certificates of merger, certificates, and other documents reasonably necessary to effect the Merger and the Bank Merger and to take any and all actions reasonably necessary or required to consummate the transactions contemplated thereby in accordance with the terms hereof.

Each of the employees of Northstar Bank who become an employee of Independent Bank after the Effective Time shall be entitled to receive, from and after the Effective Time, the same pension, profit sharing, health, welfare, incentive, vacation and other benefits as are customarily offered or afforded to similarly situated employees of Independent Bank. Each of the employees of Northstar Bank who becomes an employee of Independent Bank after the Effective Time shall receive credit for their prior service at Northstar Bank for purposes of vesting, eligibility, level of benefits or other purpose under the employee benefit plans of Independent Bank; and such persons shall not be subject to exclusions or lack of coverage for pre-existing conditions or be subject to any additional deductibles or waiting periods otherwise required for health insurance coverage. IBG shall provide each such employee with credit for any co-payments and deductibles paid in the plan year in which the Closing Date occurs in satisfying any applicable deductible or out-of-pocket requirements under any welfare plans in which such employee is eligible to participate after the Closing Date. Independent Bank shall, within 45 calendar days of the date of this Agreement, provide CBI with a list of employees of Northstar Bank to whom

Independent Bank will not offer employment and a list of employees of Northstar Bank who will be provided with retention agreements, including the terms and conditions of such retention agreements. Such list will be kept confidential by CBI and shall be disclosed only to the executive officers of CBI who need to know such information, and such information shall not be discussed with employees of Northstar Bank except upon the mutual consent of CBI and IBG, which consent will not be unreasonably withheld by either party.

Section 6.10. Adverse Changes. IBG shall promptly notify CBI in writing if any change shall have occurred or been threatened (or any development shall have occurred or been threatened involving a prospective change) in the business, financial condition, or operations of IBG and/or Independent Bank that has or may reasonably be expected to have to result in a Material Adverse Change with respect to IBG or Independent Bank or lead to a failure to obtain necessary regulatory approval of the transactions contemplated by this Agreement.

Section 6.11. Confidential Schedules. At least three (3) business days prior to the Closing, IBG agrees to provide CBI with supplemental Confidential Schedules to be delivered by IBG pursuant to this Agreement reflecting any material changes thereto between the date of this Agreement and the date thereof. Any such supplemental Confidential Schedules shall be deemed to modify the representations and warranties of IBG for purposes of determining whether there has been a breach of any representation or warranty of IBG in Article IV hereof; provided, however, that such supplemental Confidential Schedules shall not modify the representations and warranties of IBG for purposes of determining whether there has been a breach of the representations and warranties of IBG pursuant to Section 7.01 of this Agreement.

Section 6.12. Issuance of IBG Common Shares. The IBG Shares to be issued by IBG to the shareholders of CBI pursuant to this Agreement will, on the issuance and delivery to such shareholders pursuant to this Agreement, be duly authorized, validly issued, fully paid and nonassessable. The IBG Shares to be issued to the shareholders of CBI pursuant to this Agreement are and will be free of any preemptive rights of the shareholders of IBG or any other person, firm or entity. The IBG Shares to be issued to the shareholders of CBI pursuant to this Agreement pursuant to the Registration Statement which has become effective, except for IBG Shares issued to any shareholder of CBI who (i) may be deemed to be an “affiliate” (under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of IBG after completion of the Merger, or (ii) who has signed a Voting and Lock Up Agreement as contemplated by Section 5.15, will be freely tradable by each CBI shareholder who is not a dealer for purposes of the Securities Act.

Section 6.13. Access to Properties and Records. To the extent permitted by applicable law, IBG shall and shall cause each of its Subsidiaries, upon reasonable notice from CBI to IBG to: (a) afford the employees and officers and authorized representatives (including legal counsel, accountants and consultants) of CBI reasonable access to the properties, books and records of IBG and its Subsidiaries during normal business hours in order that CBI may have the opportunity to make such reasonable investigation as it shall desire to make of the affairs of IBG and its Subsidiaries, and (b) furnish CBI with such additional financial and operating data and other information as to the business and properties of IBG as CBI may, from time to time, reasonably request. No investigation by CBI or its representatives shall affect the representations and warranties set forth herein; provided, however, that CBI shall promptly notify IBG to the extent that CBI’s investigation determines that any of the representations and warranties by IBG set forth in ARTICLE IV are untrue.

Section 6.14. Rule 144 Compliance. For a period of two years after the Effective Time (or such shorter period of time as may be applicable for “affiliates” of CBI to sell IBG Shares in accordance with Rule 145 of the Securities Act), IBG will use its commercially reasonable efforts to file in a timely manner all reports with the SEC required to be filed by it pursuant to Section 13 and Section 15(d) of the Exchange Act (other than Current Reports on Form 8-K) and submit electronically and post on its corporate website, every Interactive Data File required to be submitted and posted pursuant to Rule 405 of Regulation S-T.

Section 6.15. Director and Officer Indemnification. For a period of four years after the Effective Time, IBG shall indemnify, defend and hold harmless each person entitled to indemnification from CBI or any CBI Subsidiary (each, an “Indemnified Party”) against all liabilities arising out of actions or omissions occurring at or prior to the Effective Time (including, without limitation, matters related to the negotiation, execution and performance of this Agreement or consummation of the Merger) to the same extent (including advancement of expenses) and subject to the conditions set forth in the Certificate of Formation, as applicable, of CBI or such CBI Subsidiary, or in the Bylaws of CBI or any CBI Subsidiary, as in effect on the date hereof. If IBG or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of IBG or the surviving company shall assume the obligations set forth in this Section 6.15 prior to or simultaneously with the consummation of such transaction.

Section 6.16. Election of Directors. At the IBG Meeting, IBG shall include a proposal to elect at least three individuals who are directors of CBI mutually determined by IBG and CBI (the “CBI Nominees”) to the Board of Directors of IBG; provided, however, that if the number of CBI Nominees to be nominated for election does not constitute at least 25% of the total number of IBG directors following the election of the CBI Nominees, then the number of CBI Nominees to be nominated shall be increased such that the total number of CBI Nominees will constitute not less than 25% of the total number of IBG directors following election of the CBI Nominees. The initial CBI Nominees shall be those individuals identified on Confidential Schedule 6.16. IBG shall specifically nominate one CBI Nominee to be elected as a Class I director whose term ends in 2017 (the “Class I CBI Nominee”), one CBI Nominee to be elected as a Class II director whose term ends in 2018, and one CBI Nominee to be elected as a Class III director whose term ends in 2019. IBG shall include the Class I CBI Nominee in IBG’s proxy statement, and recommend that the IBG shareholders elect, the Class I CBI Nominee to the board of directors of IBG at the 2017 annual meeting of IBG shareholders. If the number of CBI Nominees will exceed three individuals, such additional CBI Nominees shall be allocated as evenly as possible among the classes of the IBG Board of Directors, beginning with the class that has the longest remaining term as of the Closing Date. IBG shall cause Independent Bank to elect all of the CBI Nominees to the Independent Bank Board of Directors. Notwithstanding the foregoing, IBG’s obligation to nominate and recommend, as the case may be, a CBI Nominee is subject to such CBI Nominee’s compliance with IBG’s or Independent Bank’s, as the case may be, governance and ethics policies in place from time to time, and that at least two of such CBI Nominees qualify as an “independent” director as defined by applicable NASDAQ rules.

The obligations of CBI under this Agreement are subject to the satisfaction, before or at the Closing, of each of the following conditions, which may be waived in whole or in part by CBI:

Section 7.01. Representations and Warranties. All representations and warranties made by IBG in ARTICLE IV shall have been true and correct in all material respects (except for those representations and warranties which are qualified by a materiality standard, which shall be true and correct in all respects) when made and as of the Closing with the same force and effect as if such representations and warranties were made at and as of the Closing (other than those limited to a specified date, which shall speak only as to such date).

No action shall have been taken, and no statute, rule, regulation or order shall have been promulgated, enacted, entered, enforced or deemed applicable to this Agreement and the Bank Merger Agreement or the transactions contemplated hereby or thereby by any Governmental Authority, including by means of the entry of a preliminary or permanent injunction, that would (A) make this Agreement or any other agreement contemplated hereby or thereby, or the transactions contemplated hereby or thereby, illegal, invalid or unenforceable, (B) impose material limits on the ability of any party to this Agreement to consummate this Agreement or any other agreement contemplated hereby, or the transactions contemplated hereby or thereby, or (C) if the consummation of this Agreement or any other agreement contemplated hereby, or the transactions contemplated hereby or thereby, subject or could reasonably be expected to subject CBI or any CBI Subsidiary, or any of their respective officers, directors, shareholders or employees, to criminal or civil liability.

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

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their duly authorized officers as of the date first above written.
