The aforesaid [_] shares of Series B Preferred Stock (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the [_] shares of Series B Preferred Stock subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities”. The rights, powers and preferences of the Securities are set forth in the certificate of designations relating to the Securities to be filed with the Secretary of State of the State of Texas on or prior to the Closing Time (as defined herein) (the “Certificate of Designations”).

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representative deems advisable after this Underwriting Agreement (this “Underwriting Agreement”) has been executed and delivered.

The Company and the Underwriters agree that up to [_] shares of the Securities to be purchased by the Underwriters (the “Reserved Securities”) shall be reserved for sale by the Underwriters to certain eligible directors, officers, employees and other related persons (such distribution being referred to herein as the “Directed Share Program,” and such persons offered Securities in the Directed Share Program, the “Invitees”), as part of the distribution of the Securities by the Underwriters, subject to the terms of this Underwriting Agreement, the applicable rules, regulations and interpretations of the Financial Industry Regulatory Authority, Inc.

To the extent that such Reserved Securities are not orally confirmed for purchase by the Invitees by the end of the first business day after the date of this Underwriting Agreement, such Reserved Securities may be offered to the public as part of the public offering contemplated hereby.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (No. 333-230949), including the related preliminary prospectus or prospectus covering the registration of the sale of the Securities under the Securities Act of 1933, as amended (the “1933 Act”).

SECTION 2.

Sale and Delivery to Underwriters; Closing.

(a) Initial Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company, at the price per share set forth in Schedule A, the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter, plus any additional number of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof, subject, in each case, to such adjustments among the Underwriters as the Representative in its sole discretion shall make to eliminate any sales or purchases of fractional securities.

(b) Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriters, severally and not jointly, to purchase up to [_] Option Securities, at the price per share set forth in Schedule A plus accrued dividends from the Closing Time, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time upon notice by the Representative to the Company setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representative, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, subject in each case to such adjustments as the Representative in its discretion shall make to eliminate any sales or purchases of fractional shares.

(c) Payment. Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Norton Xxxx Xxxxxxxxx US LLP, 0000 Xxxx Xxxxxx, Xxxxx 0000, Xxxxxx, Xxxxx 00000, or at such other place as shall be agreed upon by the Representative and the Company, at 9:00 A.M. (Eastern time) on [_], 2019 (unless postponed in accordance with the provisions of Section 10), or such other time not later than five business days after such date as shall be agreed upon by the Representative and the Company (such time and date of payment and delivery being herein called “Closing Time”).

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representative and the Company, on each Date of Delivery as specified in the notice from the Representative to the Company.

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account(s) designated by the Company against delivery to the Representative for the respective accounts of the Underwriters of certificates for the Securities to be purchased by them. It is understood that each Underwriter has authorized the Representative, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. Sandler, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(d) Delivery of the Securities. The Securities shall be registered in such names as the Representative may request in writing at least one full business day before the Closing Time and each additional time of purchase by the Underwriters, if any. The Company shall deliver the Securities through the facilities of The Depository Trust Company (“DTC”) unless the Representative shall otherwise instruct.

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 or suspension is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. The Company will give the Representative notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)), or any amendment, supplement or revision to either any preliminary prospectus (including the prospectus included in the Registration Statement at the time it became effective) or to the Prospectus or supplement to the General Disclosure Package, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the Representative 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 Representative or counsel for the Underwriters shall reasonably object.

If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, 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 amend the Registration Statement or amend or supplement any preliminary prospectus or the Prospectus in order that such preliminary prospectus or 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 is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement any preliminary prospectus or the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or any preliminary prospectus or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters 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 contained or would contain an untrue statement of a material fact required to be stated therein or necessary to make the statements therein not misleading, the Company has promptly notified or will promptly notify the Representative 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. 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 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 that subsequent time, not misleading, the Company has promptly notified or will promptly notify the Representative 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.

SECTION 6.

Indemnification.

(a) Indemnification of Underwriters. The Company and the Bank, jointly and severally, agree to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) under the 0000 Xxx) (“Affiliates”), its and its Affiliates’ respective selling agents, partners, directors, officers, employees and agents 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), (iii) and (iv) as follows:

(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 430A Information, 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-Represented Free Writing Prospectus, any road show presentation made to investors by the Company, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto), 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;

(iii) 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 or in connection with any violation of the nature referred to in Section 6(a)(ii)(A) hereof; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iv) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representative), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by or before 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 or in connection with any violation of the nature referred to in Section 6(a)(ii)(A) hereof, to the extent that any such expense is not paid under (i), (ii) or (iii) 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 reliance upon and in conformity with the Underwriter Information. Notwithstanding the foregoing, the indemnification provided in this Section 6 shall not apply to the Bank if 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 in writing that (A) such Governmental Entity has determined that such indemnification violates Sections 23A or 23B of the Federal Reserve Act, as amended, or (B) such indemnification would give rise to civil money penalties against the Bank or the members of its board of directors. The Company and the Bank agree to notify the Representative promptly upon receipt of such written advisement or notice.

The obligations of the Company and the Bank under this Section and Section 7 below shall be in addition to any liability which the Company or the Bank may otherwise have and shall extend, upon the same terms and conditions, to each Underwriter, its Affiliates, its and its Affiliates’ respective selling agents, partners, directors, officers, employees and agents 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; and the several obligations of the Underwriters under this Section and Section 7 below shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company), each officer of the Company who signs the Registration Statement and to each person, if any, who controls the Company or the Bank, as the case may be, within the meaning of the 1933 Act.

(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 Section 6(a), 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 430A Information, any preliminary prospectus, any Issuer-Represented Free Writing Prospectus, any road show presentation made to investors by the Company, the General 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 6(a) above, counsel to the indemnified parties shall be selected by the Representative, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (which consent shall not be unreasonably withheld, and which counsel shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to its and/or other indemnified parties which are materially different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume the legal defense of such indemnified party or parties (but not to control the defense of such action as to the indemnifying party) and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party. 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 or before 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) and Section 6(a)(iii) 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.

(e) Indemnification for Reserved Securities. In connection with the offer and sale of the Reserved Securities, the Company and the Bank, jointly and severally, agree to indemnify and hold harmless each Underwriter, its Affiliates, its and its Affiliates’ respective selling agents, partners, directors, officers, employees and agents 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, from and against any and all losses, liabilities, claims, damages and expenses (including, without limitation, any legal or other expenses reasonably incurred in connection with defending, investigating, or settling any such action or claim) as incurred by them (i) caused by the failure of any Invitee to pay for and accept delivery of Reserved Securities which have been orally confirmed by the end of the first business day following the date of this Underwriting Agreement or (ii) related to, or arising out of or in connection with, the offering of the Reserved Securities.

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 and the Bank, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Underwriting 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 of the Underwriters, on the other hand, in connection with the statements or omissions, or in connection with any violation of the nature referred to in Section 6(a)(ii)(A) hereof, 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 Securities pursuant to this Underwriting Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Underwriting Agreement (before deducting expenses) received by the Company and the Bank, 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 initial public offering price of the Securities 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 or the Bank, on the one hand, or by the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or any violation of the nature referred to in Section 6(a)(ii)(A) hereof.

The Company, the Bank and the Underwriters 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 amount by which the total discounts, fees and commissions received by it exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

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.

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 each Underwriter’s Affiliates, its and its Affiliates’ respective selling agents, partners, directors, officers, employees and 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. The obligations of the Company and the Bank in this Section 7 to contribute are joint and several. The Underwriter’s respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.

Notwithstanding the foregoing, the contribution obligations in this Section 7 shall not apply to the Bank if 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 in writing that (A) such Governmental Entity has determined that such contribution obligation violates Sections 23A or 23B of the Federal Reserve Act, as amended, or (B) such contribution obligation would give rise to civil money penalties against the Bank or the members of its board of directors. The Company and the Bank agree to notify the Representative promptly upon receipt of such written advisement or notice.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Underwriting 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 investigation made by or on behalf of any Underwriter, its Affiliates, its and its Affiliates’ respective selling agents, partners, directors, officers, employees and agents 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, or by or on behalf of the Company, and shall survive delivery of and payment for the Securities.

SECTION 9. Termination of Underwriting Agreement.

(a) Termination; General. The Representative may terminate this Underwriting Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, in the reasonable judgment of the Representative, since the time of execution of this Underwriting Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, any Material Adverse Effect or if the Underwriters decline to purchase the Securities for any reason permitted under this Underwriting 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 Representative, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, (iii) 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 on 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 such system or by order of the Commission, FINRA or any other governmental authority, (iv) 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 (v) if a banking moratorium has been declared by either Federal, New York or Texas authorities.

(b) Liabilities. If this Underwriting Agreement is terminated pursuant to this Section, 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, 9, 13, 14, 16 and 17 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 Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Underwriting Agreement (the “Defaulted Securities”), the Representative shall have the right, within 36 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 Representative shall not have completed such arrangements within such 36-hour period, then:

(a) if the number of Defaulted Securities does not exceed 10% of the number of Securities 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

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

No action taken pursuant to this Section 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 Underwriting 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 Securities, as the case may be, either (i) the Representative or (ii) 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, General Disclosure Package or 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. Default by the Company. If the Company shall fail at Closing Time or at the Date of Delivery to sell and deliver the number of Securities that it is obligated to sell hereunder, then this Underwriting Agreement shall terminate without any liability on the part of any nondefaulting party; provided that the provisions of Sections 1, 4, 6, 7, 8, 9, 13, 14, 16 and 17 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company or the Bank from liability, if any, in respect of such default.

SECTION 12. Covenants of the Underwriters. In all dealings hereunder, the Representative shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representative. Each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representative, it has not made and will not make any offer relating to the Securities 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 13. 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. Notices to the Underwriters shall be directed to the Representative at Sandler X’Xxxxx & Partners, L.P., 1251 Avenue of the Americas, 0xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, attention of the General Counsel, with a copy to Norton Xxxx Xxxxxxxxx US LLP, 0000 Xxxx Xxxxxx, Xxxxx 0000, Xxxxxx, Xxxxx 00000, attention of Xxxxxxx X.

SECTION 14. Parties. This Underwriting Agreement shall each inure to the benefit of and be binding upon the Underwriters, the Company and the Bank and their respective successors. Nothing expressed or mentioned in this Underwriting Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company, and the Bank and their respective successors and the controlling persons, officers and directors and other persons or entities referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Underwriting Agreement or any provision herein contained. This Underwriting Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and the Bank and their respective successors, and said controlling persons, officers and directors and other persons or entities and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 15. No Fiduciaries. Each of the Company and the Bank, severally and not jointly, acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Underwriting Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, the Bank, or their respective shareholders, creditors, employees or any other third party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company or 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 or the Bank on other matters) and no Underwriter has any obligation to the Company or the Bank with respect to the offering contemplated hereby except the obligations expressly set forth in this Underwriting Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company or the Bank, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company and the Bank has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 16. GOVERNING LAW AND TIME. THIS UNDERWRITING AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING WITHOUT LIMITATION, SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OTHER THAN THE LAWS OF THE STATE OF NEW YORK. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 17. General Provisions. This Underwriting Agreement constitutes the entire agreement of the parties to this Underwriting Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Underwriting Agreement may be executed in two or more counterparts, each one of which shall be an original, but all of which together shall constitute one and the same instrument.
