Ladies and Gentlemen:

CBTX, Inc., a Texas corporation (the “Company”), proposes to issue and sell to the several underwriters named in Annex A hereto (the “Underwriters”) pursuant to the terms set forth herein (this “Agreement”), an aggregate of [·] shares (the “Firm Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”). The Company has also granted to the Underwriters an option to purchase up to an additional [·] shares of Common Stock (the “Option Shares”). The Firm Shares and the Option Shares are hereinafter referred to collectively as the “Shares”. Stephens Inc. and Keefe, Bruyette & Woods, Inc. have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Shares.

The Company has prepared and filed with the United States Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (File No. 333-[·]) which includes a form of prospectus to be used in connection with the public offering and sale of the Shares. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, in the form in which it became effective under the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations promulgated thereunder (the “Securities Act Regulations”), including any information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A under the Securities Act, is referred to herein as the “Registration Statement”. From and after the date and time of filing any registration statement increasing the size of the offering pursuant to Rule 462(b) under the Securities Act (a “Rule 462(b) Registration Statement”), the term “Registration Statement” shall include the Rule 462(b) Registration Statement. The prospectus, in the form first used by the Underwriters to confirm sales of the Shares or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act, is referred to herein as the “Prospectus”. Each prospectus in preliminary form that describes the Shares and the offering thereof and

is used prior to the filing of the Prospectus is referred to herein as a “preliminary prospectus”. The preliminary prospectus relating to the Shares that was included in the Registration Statement immediately prior to the Applicable Time (as defined below) is hereinafter called the “Pricing Prospectus”. The “Pricing Disclosure Package” means the Pricing Prospectus, together with the Issuer Free Writing Prospectuses (as defined below), if any, listed on Annex B hereto, and the pricing information conveyed orally to investors, and as set forth on Annex B hereto. For the purposes of this Agreement, the “Applicable Time” is [·] [a.m./p.m.], New York City time, on [·], 2017. Any “issuer free writing prospectus” (as defined in Rule 433 under the Securities Act) relating to the offering of the Shares contemplated hereunder is hereinafter called an “Issuer Free Writing Prospectus”. As used herein, “Road Show” means a “road show” (as defined in Rule 433 under the Securities Act) relating to the offering of the Shares contemplated hereby that is a “written communication” (as defined in Rule 405 under the Securities Act). All references to the Registration Statement, any preliminary prospectus, the Pricing Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”). “Testing-the-Waters Communication” means any oral or written communication with potential investors undertaken in reliance on Section 5(d) of the Securities Act. “Written Testing-the-Waters Communication” means any Testing-the-Waters Communication that is a written communication within the meaning of Rule 405 under the Securities Act. “Permitted Written Testing-the-Waters Communications” means the Written Testing-the-Waters Communications, if any, listed on Annex C hereto.

The Company and the Underwriters agree that up to [·] of the Firm Shares (the “Directed Shares”) shall be reserved for sale by the Underwriters to certain eligible officers, directors, employees, business associates and related persons of the Company and its Subsidiaries (as defined herein) and certain related persons (collectively, the “Directed Share Participants”), as part of the distribution of the Shares by the Underwriters, subject to the terms of this Agreement, the applicable rules, regulations and interpretations of the Financial Industry Regulatory Authority, Inc. (“FINRA”) and all other applicable laws, rules and regulations. To the extent that such Directed Shares are not orally confirmed for purchase, and subject to an agreement to purchase, by such eligible officers, directors, employees, business associates and related persons by the end of the first business day after the date of this Agreement, such Directed Shares may be offered to the public as part of the public offering contemplated hereby.

The Company and the Bank (as defined herein) confirm as follows their respective agreements with the Representatives and the several other Underwriters.

The only Subsidiaries of the Company are those listed on Annex D hereto, which includes (A) the subsidiaries listed on Exhibit 21 to the Registration Statement (collectively, the “Significant Subsidiaries”) and (B) certain other subsidiaries which, considered in the aggregate as a single subsidiary, do not constitute a “significant subsidiary” as defined in Rule 1-02 of Regulation S-X.

(xvi) Summaries of Legal Matters. The statements set forth in the Registration Statement, the Pricing Disclosure Package and the Prospectus under the captions “Description of Capital Stock” and “Supervision and Regulation”, insofar as they purport to describe the provisions of the laws and regulations or documents referred to therein, are accurate, complete and fair in all material respects.

The Company is not in violation of its amended and restated certificate of formation (the “Charter”), or amended and restated bylaws (the “Bylaws”); none of the Subsidiaries is in violation of its charter, bylaws or other organizational documents and neither the Company nor any of its Subsidiaries is in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company or any of its Subsidiaries is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any Subsidiary is subject (collectively, “Agreements and Instruments”), or in violation of any law or statute or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority, except for such violations or defaults that would not, singly or in the aggregate, result in a Material Adverse Effect; and the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated herein and therein, and in the Registration Statement (including the issuance and sale of the Shares and the use of the proceeds from the sale of the Shares as described in the Prospectus under the caption “Use of Proceeds”) and compliance by the Company with its obligations hereunder have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any Subsidiary pursuant to, the Agreements and Instruments (except for such conflicts, breaches or defaults or liens, charges or encumbrances that would not, singly or in the aggregate, result in a Material Adverse Effect); nor will such action result in any violation of the provisions of the Charter or Bylaws of the Company or the charter, bylaws or other organizational document of any Subsidiary; nor will such action result in any violation of any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any Subsidiary or any of their assets, properties or operations (except for such violations that would not, singly or in the aggregate, result in a Material Adverse Effect). As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any Subsidiary.

(xviii) Absence of Labor Dispute. No material labor dispute with the employees of the Company or any Subsidiary exists or, to the knowledge of the Company, is imminent. To the knowledge of the Company, there is no existing or imminent labor disturbance by the employees of any of its or any Subsidiary’s principal suppliers, customers or contractors, which, in either case, would, singly or in the aggregate, result in a Material Adverse Effect. Neither the Company nor any of the Significant Subsidiaries is engaged in any unfair labor practice; except for matters which would not, singly or in the aggregate, have a Material Adverse Effect, (A) there is (i) no unfair labor practice complaint pending or, to the Company’s knowledge, threatened against the Company or any of the Significant Subsidiaries before the National Labor Relations Board or any similar domestic or foreign body, and no grievance or arbitration proceeding arising out of or under collective bargaining agreements is pending or, to the Company’s knowledge, threatened, (ii) no strike, labor dispute, slowdown or stoppage pending or, to the Company’s knowledge, threatened against the Company or any of the Significant Subsidiaries and (iii) no union representation dispute currently existing concerning the employees of the Company or any of the Significant Subsidiaries, (B) to the Company’s knowledge, no union organizing activities are currently taking place concerning the employees of the Company or any of the Significant Subsidiaries and (C) there has been no violation of any federal, state, local or foreign law relating to discrimination in the hiring,

7

promotion or pay of employees, any applicable wage or hour laws or any provision of the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”) or any similar domestic or foreign law or the rules and regulations promulgated thereunder concerning the employees of the Company or any of the Significant Subsidiaries.

(xix) Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company, threatened, against or affecting the Company or any Subsidiary, which is required to be disclosed in the Registration Statement (other than as disclosed therein), or which, if determined adversely to the Company or any Subsidiary, singly or in the aggregate, would result in a Material Adverse Effect, or which would materially and adversely affect the properties or assets thereof, nor to the Company’s knowledge, is there any basis for any such action, suit, inquiry, proceeding or investigation; the aggregate of all pending legal or governmental proceedings to which the Company or any Subsidiary is a party or of which any of their respective property or assets is the subject which are not described in the Registration Statement, including ordinary routine litigation incidental to the business, if determined adversely to the Company or any Subsidiary, singly or in the aggregate, would not result in a Material Adverse Effect.

(xx) Bank Holding Company Act. The Company has been duly registered as, and meets in all material respects the applicable requirements for qualification as, a bank holding company. The activities of the Subsidiaries are permitted of subsidiaries of a bank holding company under applicable law and the rules and regulations of the Federal Reserve set forth in Title 12 of the Code of Federal Regulations.

(xxi) Compliance with Bank Regulatory Authorities. The Company and each of its Subsidiaries is in compliance in all material respects with all applicable laws, rules and regulations (including, without limitation, all applicable regulations and orders) of, or agreements with, the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency (the “OCC”), the Federal Deposit Insurance Corporation (“FDIC”) (collectively, the “Bank Regulatory Authorities”), the Equal Credit Opportunity Act, the Fair Housing Act, the Truth in Lending Act, the Community Reinvestment Act (the “CRA”), the Home Mortgage Disclosure Act, the Bank Secrecy Act and Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the “USA Patriot Act”), to the extent such laws or regulations apply to the Company or the Bank, as applicable. The Company and the Bank have no knowledge of any facts and circumstances, and have no reason to believe that any facts or circumstances exist, that would cause the Bank (A) to be deemed not to be in satisfactory compliance with the CRA and the regulations promulgated thereunder or to be assigned a CRA rating by federal or state banking regulators of lower than “satisfactory”, or (B) to be deemed to be operating in violation, in any material respect, of the Bank Secrecy Act of 1970 (or otherwise known as the “Currency and Foreign Transactions Reporting Act”), the USA Patriot Act or any order issued with respect to the Anti-Money Laundering Laws (as defined below). As of June 30, 2017, the Bank met or exceeded the standards necessary to be considered “well capitalized” under the regulatory framework for prompt corrective action of the OCC. The Bank has been duly chartered, is validly existing under the laws of the United States of America and holds the requisite authority to do business as a national banking association with banking powers under the laws of the United States of America. The Bank is the only depository institution subsidiary of the Company and the Bank is a member in good standing of the Federal Home Loan Bank System. The activities of the Bank are permitted under the laws and regulations of the United States and the OCC. Since December 31, 2012, the Company, the Bank and each of its subsidiaries have filed all material reports, registrations and statements, together with any required amendments thereto, that it was required to file with the Federal Reserve, the FDIC, the OCC, and any other applicable federal or state banking authorities. All such reports and statements filed with any such regulatory body or authority are collectively referred to herein as the

8

“Company Reports”. As of their respective dates, the Company Reports complied as to form in all material respects with all the rules and regulations promulgated by the Federal Reserve, the OCC and any other applicable federal or state banking authorities, as the case may be. Except as disclosed in the Registration Statement, the Pricing Disclosure Package and the Prospectus, none of the Company, the Bank or any of their respective subsidiaries is a party or subject to any formal or informal agreement, memorandum of understanding, consent decree, directive, cease-and-desist order, order of prohibition or suspension, written commitment, supervisory agreement or other written statement as described under 12 U.S.C. 1818(u) with, or order issued by, or has adopted any board resolutions at the request of, the Federal Reserve, the FDIC, the OCC or any other bank regulatory authority that restricts materially the conduct of its business, or in any manner relates to its capital adequacy, its credit policies or its management, nor have any of them been advised by any Bank Regulatory Authority that it is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any such order, decree, agreement, memorandum of understanding, extraordinary supervisory letter, commitment letter or similar submission, or any such board resolutions or that imposes any restrictions or requirements not generally applicable to bank holding companies or commercial banks. There is no unresolved violation, criticism or exception by any Bank Regulatory Authority with respect to any examination of the Company, the Bank or any of the Company’s other Subsidiaries, which would reasonably be expected to result in a Material Adverse Effect.

(xxii) Accuracy of Exhibits. There are no contracts or documents which are required to be (A) described in the Registration Statement, the Pricing Disclosure Package, the Prospectus or the documents incorporated by reference therein or (B) filed as exhibits thereto, which have not been so described and filed as required.

(xxiii) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental agency or body is necessary or required for the performance by the Company of its obligations under this Agreement in connection with the offering, issuance or sale of the Shares or the consummation of the transactions contemplated in this Agreement prior to the Closing Date, except such as have been already obtained or as may be required under the Securities Act, the Securities Act Regulations, the rules of the Nasdaq Global Select Market (“Nasdaq”), the securities laws of any state or non-U.S. jurisdiction or the rules of FINRA. All of the information provided to the Underwriters or to counsel for the Underwriters by the Company, its counsel, its officers and directors and the holders of any securities (debt or equity) or options to acquire any securities of the Company in connection with the offering of the Shares is true, complete, correct and compliant in all material respects with FINRA’s rules, and any letters, filings or other supplemental information provided to FINRA pursuant to FINRA Rules are true, complete and correct in all material respects.

(xxiv) Possession of Licenses and Permits. The Company and its Subsidiaries possess such permits, licenses, approvals, registrations, memberships, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct the business now operated by them; the Company and its Subsidiaries are in compliance with the terms and conditions of all such Governmental Licenses, except where the failure to so comply would not, singly or in the aggregate, have a Material Adverse Effect and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination of any such Governmental License or result in any other material impairment of the rights of any such Governmental License; all of the Governmental Licenses are valid and in full force and effect except where the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not reasonably be expected to have a Material Adverse Effect; and neither the Company nor any of its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses. Neither the Company nor any of its Subsidiaries has failed to file with applicable regulatory authorities any statement, report, information or form required by

9

(xxvii) Environmental Laws. Except as described in the Registration Statement and except as would not, singly or in the aggregate, result in a Material Adverse Effect, (A) neither the Company nor any of its Subsidiaries is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products, asbestos-containing materials or mold (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (B) the Company and its Subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements, (C) there are no pending or, to the knowledge of the Company, threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any of its Subsidiaries and (D) there are no events or circumstances that would result in forming the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against

No “prohibited transaction”, within the meaning of Section 406 of ERISA or Section 4975 of the Code has occurred with respect to any such Plan excluding transactions effected pursuant to a statutory or administrative exemption. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any Plan. No Plan subject to ERISA would, if such Plan were terminated, have any “amount of unfunded benefit liabilities” (as defined under ERISA). Neither the Company, the Subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any material liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any Plan or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each Plan that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, which could cause the loss of such qualification. With respect to each Plan subject to Title IV of ERISA, the minimum funding standard of Section 302 of ERISA or Section 412 of the Code, as applicable, has been satisfied (without taking into account any waiver thereof or extension of any amortization period) and is reasonably expected to be satisfied in the future (without taking into account any waiver thereof or extension of any amortization period) and the fair market value of the assets under each Plan exceeds the present value of all benefits accrued under such Plan (determined based on those assumptions used to fund such Plan).

(xxix) Internal Control Over Financial Reporting. The Company and each of its Subsidiaries maintain a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act Regulations) that complies in all material respects with the requirements of the Exchange Act and has been designed by the Company’s principal executive officer and principal financial officer and is sufficient to provide reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (C) access to assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, since the end of the Company’s most recent audited fiscal year, (i) there has been no material weakness in the Company’s internal control over financial reporting (whether or not remediated), (ii) there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting and (iii) the Company has not been advised of (a) any significant deficiencies in the design or operation of internal controls that would adversely affect the ability of the Company or any Subsidiary to record, process, summarize and report financial data, or any material weaknesses in internal controls, or (b) any fraud, whether or not material, that involves management or other employees who have a significant role in the internal controls of the Company and each of the Subsidiaries.

Based on the evaluation of the Company’s and each Subsidiary’s disclosure controls and procedures described above, to the knowledge of the Company, there is no (i) significant deficiency in the design or operation of internal controls which would adversely affect the Company’s or its Subsidiaries’ ability to record, process, summarize and report financial data or any material weaknesses in internal controls or (ii) fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s or its Subsidiaries’ internal controls. Since the most recent evaluation of the Company’s disclosure controls and procedures described above, there have been no changes in internal controls or in other factors that would significantly affect internal controls.

(xxxi) Compliance with the Sarbanes-Oxley Act. The Company has taken all necessary actions to ensure that, upon the consummation of the transactions contemplated by this Agreement, the Registration Statement, Pricing Disclosure Package and Prospectus, it will be in compliance in all material respects with all provisions of the Sarbanes-Oxley Act, with which the Company is required to comply as of such time.

The Company and the Subsidiaries have filed all other tax returns that are required to have been filed by them pursuant to applicable foreign, state, local or other law, except insofar as the failure to file such returns, singly or in the aggregate, would not result in a Material Adverse Effect, and have paid all taxes due pursuant to such returns or pursuant to any assessment received by the Company or any Subsidiary except for such taxes, if any, as are being contested in good faith and as to which adequate reserves have been provided. The charges, accruals and reserves on the books of the Company and the Subsidiaries in respect of any income and corporation tax liability for any years not finally determined are adequate to meet any assessments or re-assessments for additional income tax for any years not finally determined. Except as otherwise disclosed in the Registration Statement, the Pricing Disclosure Package and the Prospectus, there is no material tax deficiency that has been or would reasonably be expected to be asserted against the Company or any of its Subsidiaries or any of their respective properties or assets.

(a) The Company, subject to Section 4(b) hereof, will comply with the requirements of Rule 430A under the Securities Act, and will notify the Representatives promptly, and confirm the notice in writing, (A) when any post-effective amendment to the Registration Statement shall become effective, or any amendment or supplement to the Prospectus shall have been filed, to furnish the Representatives with copies thereof, and to file promptly all materials required to be filed by the Company with the Commission pursuant to Rule 433(d) under the Securities Act, (B) of the receipt of any comments from the Commission, (C) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, and (D) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424(b) under the Securities Act and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will use its reasonable best efforts to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof as soon as possible.

(b) During the period when a prospectus relating to the Shares is required by the Securities Act to be delivered (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule), the Company (A) will furnish to the Representatives for review, a reasonable period of time prior to the proposed time of filing of any proposed amendment or supplement to the Registration Statement, a copy of each such amendment or supplement, and (B) will not amend or supplement the Registration Statement without the Representatives’ prior written consent. Prior to amending or supplementing any preliminary prospectus, the Pricing Prospectus or the Prospectus, the Company shall furnish to the Representatives for review, a reasonable amount of time prior to the time of filing or use of the proposed amendment or supplement, a copy of each such proposed amendment or supplement. The Company shall not file or use any such proposed amendment or supplement without the Representatives’ prior written consent. The Company shall file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such rule.

(c) The Company shall furnish to the Representatives for review, a reasonable amount of time prior to the proposed time of filing or use thereof, a copy of each proposed free writing prospectus or any amendment or supplement thereto prepared by or on behalf of, used by, or referred to by the Company, and the Company shall not file, use or refer to any proposed free writing prospectus or any amendment or supplement thereto without the Representatives’ prior written consent. The Company shall furnish to each Underwriter, without charge, as many copies of any free writing prospectus prepared by or on behalf of, used by or referred to by the Company as such Underwriter may reasonably request. If at any time when a prospectus is required by the Securities Act to be delivered (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule) in connection with sales of the Shares (but in any event if at any time through and including the Closing Date) there occurred or occurs an event or development as a result of which any free writing prospectus prepared by or on behalf of, used by, or referred to by the Company conflicted or would conflict with the information contained in the

19

Registration Statement, the Pricing Prospectus or the Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at such time, not misleading, the Company shall promptly amend or supplement such free writing prospectus to eliminate or correct such conflict so that the statements in such free writing prospectus as so amended or supplemented will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at such time, not misleading, as the case may be; provided, that prior to amending or supplementing any such free writing prospectus, the Company shall furnish to the Representatives for review, a reasonable amount of time prior to the proposed time of filing or use thereof, a copy of such proposed amended or supplemented free writing prospectus, and the Company shall not file, use or refer to any such amended or supplemented free writing prospectus without the Representatives’ prior written consent.

(d) The Company will use its reasonable best efforts to qualify the Shares for offering and sale under the securities laws of such jurisdictions as the Representatives may reasonably request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Shares, provided that nothing in this Section 4(d) shall require the Company to qualify as a foreign corporation in any jurisdiction in which it is not already so qualified or to file a general consent to service of process in any jurisdiction or to subject itself to taxation in respect of doing business in any jurisdiction in which it is otherwise not so subject.

(e) The Company has furnished or will deliver to the Representatives, without charge, signed copies of the Registration Statement as originally filed, any Rule 462(b) Registration Statement and of each amendment to each (including exhibits filed therewith or incorporated by reference therein) and signed copies of all consents and certificates of experts, and will also, upon the Representatives’ request, deliver to the Representatives, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters. The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(f) The Company has delivered to each Underwriter, without charge, as many written and electronic copies of each preliminary prospectus and/or the Pricing Prospectus as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the Securities Act. The Company will furnish to each Underwriter, without charge, prior to 5:00 p.m., New York City time, on the business day next succeeding the date of this Agreement and from time to time thereafter during the period when the Prospectus is required to be delivered in connection with sales of the Shares under the Securities Act or the Exchange Act or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act, such number of written and electronic copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(g) If at any time following the distribution of any Permitted Written Testing-the-Waters Communication there occurred or occurs an event or development as a result of which such Permitted Written Testing-the-Waters Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Company will promptly notify the Representatives and, should the Underwriters request, will promptly amend or

20

supplement, at its own expense, such Permitted Written Testing-the-Waters Communication to eliminate or correct such untrue statement or omission.

(h) The Company will make generally available (within the meaning of Section 11(a) of the Securities Act) to its security holders and to the Representatives as soon as practicable, but not later than 45 days after the end of its fiscal quarter in which the first anniversary date of the effective date of the Registration Statement occurs, an earnings statement (in form complying with the provisions of Rule 158 under the Securities Act and satisfying the provisions of Section 11(a) of the Securities Act) covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement.

(i) The Company will use the net proceeds received by it from the sale of the Shares in the manner specified in the Pricing Prospectus under the heading “Use of Proceeds”.

(j) The Company shall engage and maintain, at its expense, a registrar and transfer agent for the Shares.

(k) The Company will use its reasonable best efforts to effect and maintain the listing of the Common Stock (including the Shares) on Nasdaq.

(l) During a period of 180 days from the date of the Prospectus (the “Lock-Up Period”), the Company will not, without the prior written consent of the Representatives, (A) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, hypothecate, establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer any shares of Common Stock or any securities convertible into or exchangeable or exercisable for Common Stock, or exercise any right with respect to the registration of any of the foregoing, file or cause to be filed any registration statement in connection therewith under the Securities Act, (B) enter into any swap, hedge or any other agreement or any transaction that transfers, in whole or in part, the economic consequence of ownership of the Common Stock, whether any such swap, hedge or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise, or (C) publicly disclose the intention to make any such offer, pledge, sale or disposition, or to enter into any such swap, hedge, transaction or other arrangement other than (W) the issuance of Common Stock or other securities (including securities convertible into or exchangeable or exercisable for Common Stock or other securities) issued as consideration for the acquisition by the Company of substantially all the securities, business, properties or other assets of another person or entity; provided that (1) the persons receiving such Common Stock or other securities enter into a written agreement substantially similar to the form of “lock-up” agreement attached hereto as Exhibit B for the remainder of the Lock-Up Period and (2) such Common Stock or other securities shall not in the aggregate exceed 10% of the Company’s outstanding shares immediately following the consummation of the offering of Shares contemplated by this Agreement, (X) the Shares to be sold hereunder, (Y) the issuance of restricted stock awards to vest after the expiration of the Lock-Up Period or options to acquire shares of Common Stock granted pursuant to the Company’s benefit plans existing on the date hereof that are described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, as such plans may be amended, or the filing of one or more registration statements on Form S-8 with respect to the issuance of securities under such benefit plans, or (Z) the issuance of shares of Common Stock upon the exercise of any such options.

(m) During the Lock-Up Period, the Company will enforce all agreements between the Company and any of its security holders that restrict or prohibit, expressly or in operation, the offer, sale or transfer of shares of Common Stock or securities convertible into or exchangeable or exercisable for any shares of Common Stock, or any of the other actions restricted or prohibited under the terms of the form of “lock-up” agreement. In addition, the Company will direct the transfer agent to place stop transfer

21

restrictions upon any such securities of the Company that are bound by such “lock-up” agreements for the duration of the periods contemplated in such agreements, including, without limitation, “lock-up” agreements entered into by the Company’s officers, directors and shareholders pursuant to Section 6(l) hereof.

(n) If the Representatives, in their sole discretion, agree to release or waive the restrictions set forth in a “lock-up” agreement described in Section 6(l) hereof for an officer or director of the Company and provides the Company with notice of the impending release or waiver at least three business days before the effective date of the release or waiver, the Company agrees to announce the impending release or waiver by a press release substantially in the form of Exhibit C hereto through a major news service at least two business days before the effective date of the release or waiver.

(o) The Company will comply with the Securities Act and the Exchange Act so as to permit the completion of the distribution of the Shares as contemplated by this Agreement, the Registration Statement, the Pricing Disclosure Package and the Prospectus. Without limiting the generality of the foregoing, the Company will, during the period when a prospectus relating to the Shares is required by the Securities Act to be delivered (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule), file on a timely basis with the Commission and the Nasdaq all reports and documents required to be filed under the Exchange Act.

(p) The Company will file with the Commission such information as may be required pursuant to Rule 463 under the Securities Act.

(q) During a period of five years from the effective date of the Registration Statement, the Company will furnish to the Representatives copies of all reports or other communications (financial or other) furnished to shareholders generally, and to deliver to the Representatives (A) as soon as they are available, copies of any reports and financial statements furnished to or filed with the Commission or any national securities exchange on which any class of securities of the Company is listed, and (B) such additional information concerning the business and financial condition of the Company as the Representatives may from time to time reasonably request (such financial statements to be on a consolidated basis to the extent the accounts of the Company and the Subsidiaries are consolidated in reports furnished to its shareholders generally or to the Commission); provided, the Company will be deemed to have furnished such reports, financial statements and other information to the extent such reports, financial statements and other information is filed on EDGAR.

(r) The Company shall not invest or otherwise use the proceeds received by the Company from its sale of the Shares in such a manner as would require the Company or any of the Subsidiaries to register as an investment company under the Investment Company Act.

(s) If the Company elects to rely upon Rule 462(b) under the Securities Act, the Company will file a Rule 462(b) Registration Statement with the Commission in compliance with Rule 462(b) by 10:00 p.m., New York City time, on the date of this Agreement, and at the time of filing either to pay to the Commission the filing fee for the Rule 462(b) Registration Statement or to give irrevocable instructions for the payment of such fee pursuant to Rule 111(b) under the Securities Act.

(t) If so requested by the Representatives, the Company shall cause to be prepared and delivered, at its expense, within one business day from the effective date of this Agreement, to the Representatives an “electronic Prospectus” to be used by the Underwriters in connection with the offering and sale of the Shares. As used herein, the term “electronic Prospectus” means a form of preliminary prospectus, Pricing Prospectus, any Issuer Free Writing Prospectus or the Prospectus, and any amendment or supplement thereto, that meets each of the following conditions: (A) it shall be encoded in an electronic

22

format, satisfactory to the Representatives, that may be transmitted electronically by the Representatives and the other Underwriters to offerees and purchasers of the Shares, (B) it shall disclose the same information as such paper preliminary prospectus, Issuer Free Writing Prospectus or the Prospectus, as the case may be, and (C) it shall be in or convertible into a paper format or an electronic format, satisfactory to the Representatives, that will allow investors to store and have continuously ready access to such preliminary prospectus, Issuer Free Writing Prospectus or the Prospectus at any future time, without charge to investors (other than any fee charged for subscription to the Internet generally). The Company hereby confirms that, if so requested by the Representatives, it has included or will include in the Prospectus filed with the Commission an undertaking that, upon receipt of a request by an investor or his or her representative, the Company shall transmit or cause to be transmitted promptly, without charge, a paper copy of such paper preliminary prospectus, Issuer Free Writing Prospectus or the Prospectus to such investor or representative.

(u) The Company will use its reasonable best efforts to ensure that the Directed Shares will be restricted as required by FINRA or FINRA rules from sale, transfer, assignment, pledge or hypothecation for a period of three months following the date of this Agreement. The Underwriters will notify the Company in writing as to which persons, if any, will need to be so restricted. At the request of the Underwriters, the Company will direct the transfer agent to place a stop transfer restriction upon such securities for such period of time. Should the Company release, or seek to release, from such restrictions any of the Directed Shares, the Company agrees to reimburse the Underwriters for any reasonable expenses (including, without limitation, reasonable legal expenses) they incur in connection with, or as a result of, such release.

(v) The Company will not take, and will use its reasonable best efforts to ensure that no affiliate of the Company will take, directly or indirectly, any action designed to cause or result in or which constitutes or would reasonably be expected to constitute stabilization or manipulation of the price of the Shares or any reference security with respect to the Shares, whether to facilitate the sale or resale of the Shares or otherwise, and the Company will, and shall use its reasonable best efforts to cause each of its affiliates to, comply with all applicable provisions of Regulation M under the Exchange Act.

(w) The Company represents and agrees that, without the prior consent of the Representatives, it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act; any such free writing prospectus the use of which has been consented to by the Company and the Representatives is listed on Annex B hereto.

(x) The Company has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; the Company represents that it has satisfied and agrees that it will satisfy the conditions under Rule 433 under the Securities Act to avoid a requirement to file with the Commission any electronic “road show” (as defined in Rule 433 under the Securities Act).

(y) During the period beginning on the date hereof and ending on the later of the fifth anniversary of the Closing Date or the date on which the Underwriters receive full payment in satisfaction of any claim for indemnification or contribution to which they may be entitled pursuant to Section 8 or Section 9 of this Agreement, neither the Company nor the Bank shall, without the prior written consent of the Representatives, take or permit to be taken any action that could result in the Bank’s common stock becoming subject to any security interest, mortgage, pledge, lien or encumbrance; provided that this covenant shall not prevent the Company from continuing to pledge the Bank’s common stock in connection with the Pledge and Security Agreement between CBFH, Inc., as borrower, and Frost Bank, as lender, dated February 1, 2015, which is filed as an exhibit to the Registration Statement (the “Pledge and

23

Security Agreement”), or from pledging or otherwise encumbering the Bank’s common stock in connection with establishment of another Company-level credit facility or line of credit to refinance or replace the Pledge and Security Agreement so long as such replacement or refinancing facility or line of credit has terms that are substantially the same as the Pledge and Security Agreement; provided further, that this covenant shall be null and void if the Federal Reserve, the OCC, the FDIC or any federal or state bank regulator or regulatory authority having jurisdiction over the Bank, by regulation, policy statement or interpretive release or by written order or written advice addressed to the Bank and specifically addressing the provisions of Section 8 or 9 hereof, permits indemnification of the Underwriters by the Bank as contemplated by such provisions.

(z) The Company and its Subsidiaries will comply with all effective applicable provisions of the Sarbanes-Oxley Act.

(aa) The Company will promptly notify the Representatives if the Company ceases to be an Emerging Growth Company at any time prior to the later of (i) completion of the distribution of Shares within the meaning of the Securities Act and (ii) completion of the Lock-Up Period.

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, any Issuer Free Writing Prospectus, the Pricing Disclosure Package or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission in any preliminary prospectus, any Issuer Free Writing Prospectus, the Pricing Disclosure Package or the Prospectus (or any amendment or supplement thereto) of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

27

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that any such settlement is effected with the written consent of the Company;

Notwithstanding the foregoing, the indemnification obligation of the Bank in this Section 8 shall be limited with respect to the Bank to the extent necessary if (a) a Governmental Entity having jurisdiction over the Bank by written communication addressed to the Bank or its board of directors, including in connection with any examination of the Bank, informs the Bank or its board of directors that such Governmental Entity has determined that such indemnification violates Sections 23A or 23B of the Federal Reserve Act, as amended, or another law, rule, regulation or policy applicable to the Bank or the Company, (b) a Governmental Entity notifies the Bank that such indemnification would result in an adverse impact on the Bank’s examination ratings or (c) such indemnification would give rise to civil money penalties or other sanctions.

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 8(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or in any preliminary prospectus, any Issuer Free Writing Prospectus, the Pricing Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 8(a) hereof, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 8(b) hereof, counsel to the indemnified parties shall be selected by the Company. In any action the defense of which is assumed by the indemnifying party pursuant to this Agreement, an

28

indemnified party shall have the right to participate in such action and to retain its own counsel at the expense of such indemnified party, except that the fees and expenses of such counsel shall be borne by the indemnifying party if (i) the indemnifying party and such indemnified party shall have mutually agreed in writing to the retention of such counsel, (ii) the indemnifying party shall have failed in a timely manner to assume the defense and employ counsel reasonably satisfactory to the indemnified party in such action, or (iii) the indemnified party reasonably determines that defenses may be available to the indemnified party which are not available to the indemnifying party or may not be consistent with the best interests of the indemnifying party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 8 or Section 9 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

Section 9. Contribution.

If the indemnification provided for in Section 8 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Bank, on the one hand, and the Underwriters, on the other hand, from the offering of the Shares pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Bank, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Bank, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Shares pursuant to this Agreement (before deducting expenses) received by the Company and the Bank, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Shares as set forth on the cover of the Prospectus.

The relative fault of the Company and the Bank, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company and the Bank or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Bank and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take

29

account of the equitable considerations referred to above in this Section 9. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 9 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against, or appearing as a witness or providing information or documents in connection with, any litigation, or any formal or informal request, investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting discount received by such Underwriter in connection with the Shares underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the number of Firm Shares set forth opposite their respective names in Annex A hereto and not joint.

For purposes of this Section 9, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each Underwriter’s Affiliates, officers, directors and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. Notwithstanding the foregoing, the contribution obligations of the Bank in this Section 9 shall be limited with respect to the Bank to the extent necessary if (a) a Governmental Entity having jurisdiction over the Bank by written communication addressed to the Bank or its board of directors, including in connection with any examination of the Bank, informs the Bank or its board of directors that such Governmental Entity has determined that such contribution violates Sections 23A or 23B of the Federal Reserve Act, as amended, or another law, rule, regulation or policy applicable to the Bank or the Company, (b) a Governmental Entity notifies the Bank that such contribution would result in an adverse impact on the Bank’s examination ratings or (c) such contribution would give rise to civil money penalties or other sanctions..

Section 10. Defaulting Underwriter.

(a) If any Underwriter or Underwriters default in its or their obligations to purchase Shares hereunder on the Closing Date or any Option Closing Date and the aggregate number of Shares that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of Shares that the Underwriters are obligated to purchase on such Closing Date or Option Closing Date, as the case may be, the Representatives may make arrangements satisfactory to the Company for the purchase of such Shares by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date or Option Closing Date, as the case may be, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Shares that such defaulting Underwriters agreed but failed to purchase on such Closing Date or Option Closing Date, as the case may be. If any Underwriter or Underwriters so default and the aggregate number of Shares with respect to which such default or defaults occur exceeds 10% of the total number of Shares that the Underwriters are obligated to purchase on such Closing Date or Option Closing Date, as the case may be, and arrangements satisfactory to the Representatives and the Company for the purchase of such Shares by other persons are not made within 36 hours after such default, this Agreement will terminate, subject to the provisions of Section 12, without liability on the part of any non-defaulting

30

Underwriter or the Company, except as provided in Section 12. Nothing herein will relieve a defaulting Underwriter from liability for its default.

(b) In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Date or the relevant Option Closing Date, as the case may be, for a period not exceeding seven days, in order to effect any required changes to the Registration Statement or Prospectus or any other documents or arrangements. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

Section 11. Termination.

Notwithstanding anything herein contained, this Agreement (or the obligations of the several Underwriters with respect to any Option Shares which have yet to be purchased) may be terminated, subject to the provisions of Section 12, in the absolute discretion of the Representatives, by notice given to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or the Option Closing Date, as the case may be, (a) trading generally on the NYSE or on Nasdaq shall have been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other governmental or regulatory authority, (b) trading of any securities of or guaranteed by the Company or any Subsidiary shall have been suspended on any exchange or in any over-the-counter market, (c) a general moratorium on commercial banking activities in New York shall have been declared by Federal or New York State authorities or a new restriction materially adversely affecting the distribution of the Firm Shares or the Option Shares, as the case may be, shall have become effective, (d) there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof, declaration by the United States of a national emergency or war, or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, including as a result of terrorist activities, or (e) there has occurred any other Material Adverse Effect, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Shares to be delivered on the Closing Date or Option Closing Date, as the case may be, or to enforce contracts for the sale of the Shares.

If this Agreement is terminated pursuant to this Section 11, such termination will be without liability of any party to any other party except as provided in Section 5 and Section 12 hereof; provided, that the provisions of Section 8 shall at all times be effective and shall survive such termination.

Section 12. Effect of Termination.

(a) The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers, of the Bank and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company, the Bank or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares.

(b) If this Agreement is terminated pursuant to Section 6, Section 10 or Section 11 or if for any reason the purchase of any of the Shares by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by them pursuant to Section 5, the respective obligations of the Company, the Bank and the Underwriters pursuant to Section 8 and the provisions of Section 10 and Section 11 shall remain in effect and, if any Shares have been purchased

31

hereunder, the representations and warranties in Section 1 and all obligations under Section 5, Section 6 and Section 8 shall also remain in effect.

(c) If this Agreement shall be terminated by the Underwriters, or any of them, under Section 6, Section 10 or Section 11 or otherwise because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason any of the Company shall be unable to perform its obligations under this Agreement or any condition of the Underwriters’ obligations cannot be fulfilled, the Company agrees to reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement or the offering contemplated hereunder.

Section 13. Covenants of the Underwriters.

Each Underwriter, severally and not jointly, covenants with the Company not to take any action that would result in the Company being required to file with the Commission pursuant to Rule 433(d) a “free writing prospectus” prepared by or on behalf of such Underwriter that otherwise would not, but for such actions, be required to be filed by the Company under Rule 433(d).

Section 14. Successors; Assigns.

This Agreement shall inure to the benefit of and be binding upon the Company and the Bank and the Underwriters, the officers and directors of the Company referred to herein, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation, other than the Underwriters, the Company, the Bank, and their respective successors and the controlling persons and officers and directors referred to in Section 8 and Section 9 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Shares from any Underwriter shall be deemed to be a successor or assign by reason merely of such purchase.

Section 15. Notices.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given upon receipt thereof by the recipient if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be given to the Representatives, c/o Stephens Inc., 111 Center Street, Little Rock, Arkansas 72201, (fax no.: [·]), Attention: Legal Dept. and Keefe, Bruyette & Woods, Inc., 787 Seventh Avenue, 4th Floor, New York, New York 10019, Attention: Equity Capital Markets (fax no.: [·]), with a copy (which shall not constitute notice) to Covington & Burling LLP, One CityCenter, 850 Tenth Street, N.W., Washington, D.C. 20001, Attention: Michael P.

(b) The Company and the Bank each acknowledge and agree that (i) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the public offering price of the Shares and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Bank on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company and the Bank or their respective shareholders, creditors, employees or any other party, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company and the Bank with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company and the Bank on other matters) or any other obligation to the Company and the Bank except the obligations expressly set forth in this Agreement, and (iv) each of the Company and the Bank has consulted its own legal and financial advisors to the extent it deemed appropriate.

(c) The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriters’ investment banking divisions. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transaction for its own account or the account of its customers and hold long or short positions in debt or

(d) Notwithstanding anything herein to the contrary, the Company is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

(e) This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Bank and the Underwriters, or any of them, with respect to the subject matter hereof.

(g) This Agreement may not be amended or modified unless in writing signed by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.

As Representatives of the several Underwriters

Re: Proposed Public Offering of Common Stock by CBTX, Inc.

Ladies and Gentlemen:

The undersigned, a shareholder, an executive officer and/or director of CBTX, Inc., a Texas corporation (the “Company”), understands that Stephens Inc. (“Stephens”) and Keefe, Bruyette & Woods, Inc. (“KBW,” and together with Stephens, the “Representatives”), as representatives of the several Underwriters (each an “Underwriter” and collectively, the “Underwriters”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company providing for the public offering (the “Offering”) of shares of the Company’s common stock, par value $0.01 per share (including any securities convertible into or exchangeable or exercisable for such common stock, the “Common Stock”).

In recognition of the benefit that the Offering will confer upon the undersigned as a shareholder, executive officer and/or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each Underwriter to be named in the Underwriting Agreement that, commencing on the date hereof and ending on, and including, the date that is 180 days from the date of the Underwriting Agreement (such 180-day period being referred to herein as the “Lock-Up Period”), the undersigned will not (and will cause any spouse or immediate family member (as defined in Rule 16a-1(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of the spouse or the undersigned living in the undersigned’s household, any partnership, corporation or other entity within the undersigned’s control, and any trustee of any trust that holds Common Stock for the benefit of the undersigned or such spouse or immediate family member not to), without the prior written consent of the Representatives, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, hypothecate, establish an open “put equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer any shares of Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or exercise any right with respect to the registration of any of the foregoing, or file or cause to be filed any registration statement in connection therewith under the Securities Act of 1933, as amended, (ii) enter into any swap, hedge or any other agreement or any transaction that transfers, in whole or in part, the economic consequence of ownership of the Common Stock, whether any such swap, hedge or transaction is to be settled by delivery

B-1

of Common Stock or other securities, in cash or otherwise, or (iii) publicly disclose the intention to make any such offer, pledge, sale or disposition, or to enter into any such swap, hedge, transaction or other arrangement. For the avoidance of doubt, if the undersigned is an officer or director of the Company, the undersigned acknowledges that the foregoing shall be applicable to any shares of Common Stock the undersigned may purchase through the directed share program of the Offering.

Notwithstanding the foregoing, (A) the foregoing restrictions shall not apply to pledges in a bona fide transaction that are in effect as of the date hereof to a lender to the undersigned, as disclosed in writing to the Representatives; and (B) the undersigned may transfer the undersigned’s shares of Common Stock (i) as a bona fide gift or gifts including through a distribution by a trust, family limited partnership, corporation or other entity; provided that the donee or donees agree to be bound in writing by the restrictions set forth herein; (ii) to any corporation, trust, family limited partnership or other entity for the direct or indirect benefit of the undersigned or the immediate family of the undersigned; provided, that such corporation or other entity or the trustee of the trust or general partner of the family limited partnership, as the case may be, agrees to be bound by the restrictions set forth herein; and provided further, that any such transfer shall not involve a disposition for value; (iii) by will or intestate succession to executors, administrators, testamentary trustees, legatees or beneficiaries; provided that the recipients of such transfers agree to be bound in writing by the restrictions set forth herein; (iv) to the Company, to satisfy any tax withholding obligations of the Company or the undersigned, or to satisfy the exercise price of stock options by the undersigned, upon the exercise or vesting of equity awards outstanding or hereinafter granted under any exercise by the undersigned of stock options or vesting of outstanding restricted stock awards or other similar equity incentive awards that have been granted by the Company prior to, and are outstanding as of, the date of the Underwriting Agreement (or are granted after the date of the Underwriting Agreement pursuant to a plan or arrangement that is in place prior to the date of the Underwriting Agreement); (v) pursuant to a domestic relations order, divorce decree, or court order; provided that the recipients of such transfers agree to be bound in writing by the restrictions set forth herein; or (vi) with the prior written consent of the Representatives.

The undersigned represents and warrants that the undersigned beneficially owns the shares of Common Stock covered by this letter agreement and that the undersigned now has and, except as contemplated by clauses (B)(i) through (B)(vi) above, for the duration of this letter agreement will have good and marketable title to the undersigned’s shares of Common Stock, free and clear of all liens, encumbrances, and claims whatsoever except for such liens, encumbrances, and claims as may exist as of the date hereof, as disclosed in writing to the Representatives. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock, except in compliance with this letter agreement. In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this letter agreement.

In addition, the undersigned agrees that, during the Lock-Up Period, without the prior written consent of the Representatives (which consent may be withheld in their sole discretion): (i) the undersigned will not request, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock and (ii) the undersigned waives any and all notice requirements and rights with respect to the registration of any shares of Common Stock pursuant to any agreement, understanding or otherwise to which the undersigned is a party.

The undersigned represents and warrants that the undersigned has full power and authority to enter into this letter agreement. The undersigned agrees that the provisions of this letter agreement shall be binding also upon the successors, assigns, heirs and personal representatives of the undersigned.

B-2

The undersigned understands that, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the shares of Common Stock to be sold thereunder, the undersigned shall be released from all obligations under this letter agreement. Notwithstanding anything herein to the contrary, this letter agreement shall automatically terminate and be of no further effect as of 5:00 p.m. New York City time on December 31, 2017, if a closing for the Offering has not yet occurred as of that time.

This letter agreement shall be governed by and construed in accordance with the laws of the State of New York.

[Signature page follows]

B-3

The undersigned understands that the Company and the Underwriters are relying upon this letter agreement in proceeding toward consummation of the Offering. The undersigned further understands that this letter agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.
