Ladies and Gentlemen:

Spirit of Texas Bancshares, Inc., a Texas corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to the several underwriters named in Schedule A hereto (each, an “Underwriter” and, collectively, the “Underwriters”), for which Xxxxxxxx Inc. and Xxxxx, Xxxxxxxx & Xxxxx, Inc. are acting as representatives (together, the “Representatives”), an aggregate of 2,000,000 shares (the “Firm Shares”) of common stock, no par value per share, of the Company (“Common Stock”) and, at the election of the Underwriters through the Representatives, up to an additional 300,000 shares of Common Stock (the “Option Shares” and together with the Firm Shares, the “Shares”).

The Company understands that the Underwriters propose to make a public offering of the Shares as soon as the Underwriters deem advisable after this Agreement has been executed and delivered.

The Company and the Underwriters agree that up to 95,162 Shares to be purchased by the Underwriters (the “Reserved Shares”) shall be reserved for sale by the Underwriters to certain executive officers and directors of the Company and its subsidiaries (the “Invitees”), 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 Reserved Shares are not orally confirmed for purchase by the Invitees by the end of the first business day after the date of this Agreement, such Reserved Shares may be offered to the public as part of the public offering contemplated hereby.

The Company has filed with the United States Securities and Exchange Commission (the “Commission”) a shelf registration statement on Form S-3 (File No. 333-232092), which includes the form of prospectus covering the registration of the Shares under the Securities Act of 1933, as amended (the “1933 Act”). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus supplement in accordance with the provisions of Rule 430A and/or Rule 430B of the

rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”) and paragraph (b) of Rule 424 of the 1933 Act Regulations (“Rule 424(b)”). The information included in such prospectus supplement that was omitted from the registration statement at the time it became effective but is deemed to be part of such registration statement at the time it became effective pursuant to paragraph (b) of Rule 430A or Rule 430B of the 1933 Act Regulations is referred to as “Rule 430 Information.” Such registration statement, including any amendments thereto, the exhibits and schedules thereto, if any, but excluding Form T-1, and the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, at the time it became effective, and including the Rule 430 Information, as applicable, is herein called the “Registration Statement.” Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as a “Rule 462(b) Registration Statement” and, after such filing, the term “Registration Statement” shall include all such Rule 462(b) Registration Statements. The form of prospectus appearing in the Registration Statement at the time of its initial effectiveness and including the documents incorporated by reference therein, is hereinafter called the “Base Prospectus.” The Base Prospectus, as supplemented by the final prospectus supplement used in connection with the offering of the Shares as filed with the Commission pursuant to Rule 424(b), and including the documents incorporated by reference therein, is hereinafter called the “Prospectus.” The Base Prospectus, as supplemented by any preliminary prospectus supplement in the form of which has been or will be filed with the Commission pursuant to Rule 424(b) relating to the offering of the Shares that omits the Rule 430 Information, and including the documents incorporated by reference therein, is hereinafter called a “preliminary prospectus.” All references herein to any “preliminary prospectus” shall be deemed to mean and include, without limitation, the Statutory Prospectus (as defined below). For purposes of this Agreement, all references to the Registration Statement, the Base Prospectus, any preliminary prospectus, the 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 or any successor system thereto (“XXXXX”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, the Base Prospectus, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information that are incorporated therein by reference; and all references in this Agreement to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any preliminary prospectus or the Prospectus shall be deemed to mean and include the filing of a post-effective amendment, any document under the Securities Exchange Act of 1934, as amended (the “1934 Act”), which is incorporated therein by reference, or form of prospectus.

SECTION 3. Covenants of the Company. The Company covenants and agrees with each of the Underwriters as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b), will comply with the requirements of Rule 430A or Rule 430B, as applicable, and will notify the Representatives immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or any preliminary prospectus or any amended Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) 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, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, any Rule 462(b) Registration Statement or any respective post-effective amendment thereto or of any order preventing or suspending the use of the Base Prospectus, any preliminary prospectus, or the 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 or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Shares. The Company will promptly effect the filings necessary pursuant to Rule 424(b) in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)) 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 make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. The Company will give the Representatives notice of its intention to file or prepare any amendment or supplement to the Registration Statement (including any filing under Rule 462(b) of the 1933 Act Regulations), the Base Prospectus, any preliminary prospectus, or the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall object.

(c) Delivery of Registration Statement. The Company has made available or will deliver to the Representatives and counsel for the Underwriters, without charge, conformed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated

by reference therein and documents incorporated or deemed to be incorporated by reference therein) and conformed copies of all consents and certificates of experts, and will also 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 each Underwriter will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Company has delivered to each Underwriter, without charge, as many copies of the Base Prospectus and any preliminary prospectus as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to each Underwriter, without charge, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to each Underwriter will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and in the Registration Statement, the General Disclosure Package and the Prospectus. If at any time when a prospectus is (or, but for the exception afforded by Rule 172 of the 1933 Act Regulations, would be) required by the 1933 Act (or in lieu thereof the notice referred to in Section 173(a) of the 1933 Act Regulations) to be delivered in connection with sales of the Shares ending no later than nine months from the date hereto (the “Delivery Period”), any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to (i) amend the Registration Statement in order that the Registration Statement will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it (or in lieu thereof the notice referred to in Section 173(a) of the 1933 Act Regulations) is delivered to a purchaser, or (iii) if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly (A) give the Representatives written notice of such event or condition, (B) prepare and file with the Commission, subject to Section 3(b) of this Agreement, such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements and use its best efforts to have any amendment to the Registration Statement declared effective by the Commission as soon as possible, and (C) furnish to each Underwriter such number of copies of such amendment or supplement as such Underwriter may reasonably request. If at any time following issuance of an Issuer-Represented Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer-Represented Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement 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 that subsequent time, not misleading, the Company has promptly notified or will promptly notify the Representatives and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer-Represented Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(f) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriters, to qualify the Shares for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications in effect for the Delivery Period; provided, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Shares have been so qualified, the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for the Delivery Period. The Company will also supply the Underwriters with such information as is necessary for the determination of the legality of the Shares for investment under the laws of such jurisdiction as such Underwriter may request.

(g) Earning Statement. The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable, but in any event not later than 16 months after the effective date of the Registration Statement, an earning statement (as defined and in the form complying with the provisions of Rule 158 of the 1933 Act Regulations and satisfying the provisions of Section 11(a) of the 1933 Act).

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

The foregoing sentence shall not apply to (A) the Shares to be sold hereunder, (B) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Prospectus, or (C) any shares of Common Stock issued or options to purchase Common Stock granted pursuant to existing employee benefit plans of the Company referred to in the Prospectus provided that such options shall not be vested and exercisable within the 90-day period referred to above. The Company also agrees that during the Lock-Up Period, other than for the sale of Common Stock hereunder, the Company will not file any registration statement, preliminary prospectus or prospectus, or any amendment or supplement thereto, under the 1933 Act for any such transaction or which registers, or offers for sale, Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, except for any registration statement on Form S-8 relating to employee benefit plans and any registration statement on Form S-4 concerning the Merger Agreement and the transactions contemplated thereby.

(k) Reporting Requirements. The Company, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will file all documents required to be filed by the Company with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations.

(l) Lock-up Agreements. The Company agrees to enforce its rights under any of its existing registration rights agreements and/or shareholders’ agreement to restrict the transfer of securities within the 90-day period following the Closing Time.

(m) Issuer Free Writing Prospectus. The Company represents and agrees that, unless it obtains the prior consent of the Representatives, it has not made and will not make any offer relating to the Shares that would constitute an “issuer free writing prospectus,” as defined in Rule 433, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Representatives is hereinafter referred to as a “Permitted Issuer Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Issuer Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Issuer Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

(n) DTC. The Company will cooperate with the Representatives and use its best efforts to permit the Shares to be eligible for clearance, settlement and trading through the facilities of DTC, if required.

(o) Emerging Growth Company. The Company will promptly notify the Representatives if the Company ceases to be an Emerging Growth Company at any time prior to completion of the distribution of the Shares within the meaning of the 1933 Act.

SECTION 6. Indemnification.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) of the 1933 Act Regulations) (“Affiliates”), its selling agents, directors, officers and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the extent and in the manner set forth in clauses (i), (ii) and (iii) below:

(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 the Rule 430 Information, if applicable, 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 the Base Prospectus, any preliminary prospectus, the Prospectus, the General Disclosure Package or any Issuer-Represented Free Writing Prospectus or the omission or alleged omission therefrom 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;

(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 (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against, or appearing as a witness or providing information or documents in connection with, any litigation or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission to the extent that any such expense is not paid under (i) or (ii) above;

provided, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement, the Base Prospectus, any preliminary prospectus, the Prospectus, the General Disclosure Package or any Issuer-Represented Free Writing Prospectus in reliance upon and in conformity with the Underwriter Information.

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally, and not jointly, 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 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, 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 the Rule 430 Information, if applicable, or the Base Prospectus, any preliminary prospectus, the Prospectus, the General Disclosure Package or any Issuer-Represented Free Writing Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the written information furnished to the Company through the Representatives by or on behalf of that Underwriter specifically for use therein, which information the parties hereto agree is limited to 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 6(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified 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 6 or Section 7 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.

(d) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 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 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 on the one hand and of 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 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, on the one hand, and the total underwriting discount and commissions received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Shares as set forth on the cover of the Prospectus.

The relative fault of the Company, 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 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 and each Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 7 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 account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any 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 7, 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 0000 Xxx) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 7 to contribute are several in proportion to their respective underwriting obligations and not joint.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and such Underwriter’s Affiliates 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 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. The indemnity and contribution provisions contained in Section 6 and Section 7 hereof and all representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any (i) investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors, or by or on behalf of the Company, and (ii) delivery of and payment for the Shares.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Base Prospectus, any preliminary prospectus or the Prospectus, any Material Adverse Effect in the judgment of the Representatives or if the Underwriters shall decline to purchase the Shares for any reason permitted under this Agreement; (ii) if 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 or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, including, without limitation, as a result of terrorist activities, 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 or to enforce contracts for the sale of the Shares, (iii) there shall not have been any decrease in or withdrawal of the rating of any debt securities or preferred securities of the Company or any of its subsidiaries by any “nationally recognized statistical rating organization” (as defined for purposes of Section 3(a)(62) of the 0000 Xxx) or any notice given of any intended or potential decrease in or withdrawal of any such rating or of a possible change in any such rating that does not indicate the direction of the possible change, (iv) if trading in any securities of the Company has been suspended or materially limited by the Commission or Nasdaq, or if trading generally on the New York Stock Exchange or Nasdaq has 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 order of the Commission, FINRA or any other governmental authority, (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear Systems in Europe, or (vi) if a general moratorium on commercial banking activities has been declared by federal, New York or Texas authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 15, 16, 17 and 18 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time or a Date of Delivery to purchase the Shares which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i) if the number of Defaulted Securities does not exceed 10% of the number of Shares to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

(ii) if the number of Defaulted Securities exceeds 10% of the number of Shares to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase, and the Company to sell, the Option Shares to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Shares, as the case may be, either the Representatives or the Company shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Use of Free Writing Prospectuses by Underwriters. Each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Shares that would constitute an “issuer free writing prospectus,” as defined in Rule 433, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission.

SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (iv) each Underwriter and its Affiliates is engaged in a broad range of transactions that involve interests that differ, or may differ, from those of the Company and shall have no obligation to disclose any information regarding such transactions or interests, and (v) no Underwriter has provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 15. GOVERNING LAW AND TIME.

SECTION 16. Trial by Jury. Each of the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its shareholders and affiliates) and the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or proceeding brought in any Specified Court. Each of the parties hereto irrevocably and unconditionally waives any objection to the laying of venue of any suit, action or proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any such suit, action or proceeding brought in any Specified Court has been brought in an inconvenient forum.

As Representatives of the Underwriters

named in Schedule A of the Underwriting Agreement

Re: Proposed Public Offering of Common Stock by Spirit of Texas Bancshares, Inc.

Ladies and Gentlemen:

The undersigned, a shareholder, executive officer and/or director of Spirit of Texas Bancshares, Inc., a Texas corporation (the “Company”), understands that Xxxxxxxx Inc. (“Xxxxxxxx”) and Xxxxx, Xxxxxxxx & Xxxxx, Inc. (“KBW,” together with Xxxxxxxx, the “Representatives”), as representatives of the several Underwriters (each an “Underwriter,” collectively the “Underwriters”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company providing for the public offering of shares of the Company’s common stock, no par value per share (including any securities convertible into or exercisable for such common stock, the “Common Stock”).

In recognition of the benefit that such an offering will confer upon the undersigned as an executive officer and/or director of the Company, or as a holder of the Company’s Common Stock, 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, during a period of 90 days from the date of the Underwriting Agreement (the “Lock-Up Period”), the undersigned will not, without the prior written consent of each Representative, 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 Securities Exchange Act of 1934, as amended, or otherwise dispose of or transfer any shares of the Company’s Common Stock or any securities convertible into or exchangeable or exercisable for 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 file or cause to be filed any registration statement under the Securities Act of 1933, as amended, with respect to any of the foregoing, (ii) enter into any swap, hedge or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap, hedge or transaction is to be settled by delivery of shares 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.

Notwithstanding the foregoing, the undersigned may transfer the undersigned’s shares of Common Stock (i) as a bona fide gift or gifts or by will or intestate succession, provided that the donee or donees agree to be bound in writing by the restrictions set forth herein; (ii) to any trust or family limited

partnership for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that 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) pledged in a bona fide transaction which is outstanding prior to or as of the date hereof to a lender to the undersigned and as disclosed in writing to the Representatives prior to the execution of this agreement; (iv) pursuant to the exercise by the undersigned of stock options that have been granted by the Company prior to, and are outstanding as of, the date of the Underwriting Agreement, where the shares of Common Stock received upon any such exercise are held by the undersigned, individually or as fiduciary, in accordance with the terms of this agreement; (v) to the Company for payment of taxes due and owing as a result of the vesting of restricted share awards that have been granted by the Company prior to the date of the Underwriting Agreement and are disclosed in the General Disclosure Package (as defined in the Underwriting Agreement)¹; or (vi) with the prior written consent of each Representative. For purposes of this agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

The undersigned represents and warrants that the undersigned beneficially owns the shares of Common Stock covered by this agreement and that the undersigned now has and, except as contemplated by clauses (i) through [(v)][(vi)] above, for the duration of this 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 with respect to any liens, encumbrances and claims that were in existence on the date hereof. 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 Common Stock, except in compliance with this 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 agreement.

In addition, the undersigned agrees that, during the Lock-Up Period, without the prior written consent of each Representative (which consent may be withheld in its sole discretion): (i) the undersigned will not request, make any demand for or exercise any right with respect to, the registration of any Common Stock or any shares of Common Stock or securities convertible into or exchangeable or exercisable for any shares of Common Stock (“Related Securities”) and (ii) the undersigned waives any and all notice requirements and rights with respect to the registration of any shares of Common Stock or Related Securities 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 agreement. The undersigned agrees that the provisions of this agreement shall be binding also upon the successors, assigns, heirs and personal representatives of the undersigned.

The undersigned understands that, if the Underwriting Agreement does not become effective on or prior to [ ], 2019, 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 agreement.

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

[Signature page follows]

¹	NTD: This carve-out will be included only for those executives that have equity awards vesting during the lock-up period.

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


Very truly yours,
