Ladies and Gentlemen:

Investar Holding Company, a Louisiana corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell to the Underwriters named in Schedule I hereto (the “Underwriters”), for whom Sandler X’Xxxxx & Partners, L.P. is acting as Representative (the “Representative”), an aggregate of 2,875,000 shares (the “Firm Shares”) of common stock, $1.00 par value per share, of the Company (the “Common Stock”) and all or any part of 431,250 additional shares of Common Stock (the “Optional Shares”) pursuant to the option described in Section 2 hereof to cover over-allotments, if any (the Firm Shares and the Optional Shares that the Underwriter elects to purchase pursuant to Section 2 hereof being collectively called the “Shares”). A primary purpose of the proposed offering is to support the long-term growth of the Company and Investar Bank (the “Bank”), a Louisiana-chartered bank, as set forth in the Registration Statement (as defined below).

The Underwriters have agreed to reserve 115,000 Firm Shares to be purchased under this Agreement for sale at the public offering price to the Company’s directors, officers and certain other persons (collectively, “Directed Share Purchasers”) pursuant to a directed share program (the “Directed Share Program”). The Firm Shares to be sold under the Company’s Directed Share Program by the Underwriters are referred to hereinafter as the “Directed Shares.” Any Directed Shares not purchased through the Directed Share Program will be offered to the public by the Underwriters as Firm Shares.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (No. 333-196014), including the related preliminary prospectus or prospectuses, 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 in accordance with the provisions of Rule 430A (“Rule 430A”) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”) and paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations. The information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to paragraph (b) of Rule 430A is referred to as “Rule 430A Information.” Each prospectus used before such registration statement became effective, and any prospectus that omitted the Rule 430A Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a “preliminary prospectus.” Such registration statement, including the amendments thereto, the exhibits and any schedules thereto, at the time it became effective, and including the Rule 430A Information, is herein called the “Registration Statement.” The term “Effective Date” shall mean each date that the Registration Statement and any post-effective amendment or amendments thereto became or become effective. Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the “Rule 462(b) Registration Statement,” and after such filing the term “Registration Statement” shall include the Rule 462(b) Registration Statement. The final prospectus in the form first filed with the Commission pursuant to Rule 424(b) under the 1933 Act is herein called the “Prospectus.”

For purposes of this Agreement, all references to the Registration Statement, 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 (“XXXXX”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, 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 which is incorporated by reference in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be.

As used herein, the term “Regulatory Agency” means any Governmental Entity having supervisory or regulatory authority with respect to the Company or its subsidiary, including, but not limited to, any federal or state agency charged with the supervision or regulation of depositary institutions or holding companies of depositary institutions, or engaged in the insurance of depositary institution deposits.

(xxxiii) Any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, its subsidiary or their “ERISA Affiliates” (as defined below) are in compliance with ERISA, except where the failure to be in compliance with ERISA would not result in a Material Adverse Effect. “ERISA Affiliate” means, with respect to the Company or a subsidiary, any member of any group of organizations described in Section 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company or such subsidiary is a member. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiary or any of their ERISA Affiliates. No “employee benefit plan” established or maintained by the Company, its subsidiary or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA). None of the Company, its subsidiary nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (A) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (B) Sections 412, 4971, 4975 or 4980B of the Code. Each “employee benefit plan” established or maintained by the Company, its subsidiary or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code has received a favorable determination or approval letter from the Internal Revenue Service regarding its qualification under such section, or is maintained in the form of a pre-approved document, the sponsor of which has obtained a favorable determination with respect to such pre-approved document, and nothing has occurred whether by action or failure to act, which would cause the loss of such qualification.

(xxxiv) The Company and its subsidiary, taken as a whole, are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts that the Company reasonably believes is adequate for its business on a consolidated basis. Neither the Company nor its subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect. Neither the Company nor its subsidiary has been denied any insurance coverage which it has sought or for which it has applied.

(xxxv) Except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, there are no contracts, agreements or understandings between the Company and any person other that would give rise to a valid claim against the Company, or the Underwriters, for a brokerage commission, finder’s fee or other like payment.

The Company has made adequate charges, accruals and reserves in the applicable Financial Statements referred to in Section 1(a)(iv) above in respect of all federal, state and foreign income and franchise taxes for all periods as to which the tax liability of the Company or its consolidated subsidiary has not been finally determined.

(xliii) Each of the Company and its subsidiary has good and marketable title to all securities held by it (except securities sold under repurchase agreements, pledged to secure deposits or derivative contracts or held in any fiduciary or agency capacity) free and clear of any lien, claim, charge, option, encumbrance, mortgage, pledge or security interest or other restriction of any kind, except to the extent such securities are pledged in the ordinary course of business to secure obligations of the Company or its subsidiary and except for such defects in title or liens, claims, charges, options, encumbrances, mortgages, pledges or security interests or other restrictions of any kind that would not, individually or in the aggregate, result in a Material Adverse Effect. Such securities are valued on the books of the Company and its subsidiary in accordance with GAAP.

(xliv) Any and all material swaps, caps, floors, futures, forward contracts, option agreements (other than employee stock options and restricted stock units) and other derivative financial instruments, contracts or arrangements, whether entered into for the account of the Company or its subsidiary or for the account of a customer of the Company or its subsidiary, were entered into in the ordinary course of business and in accordance with applicable laws, rules, regulations and policies of all applicable regulatory agencies and with counterparties reasonably believed to be financially responsible at the time. The Company and its subsidiary have duly performed all of their obligations thereunder to the extent that such obligations to perform have accrued, and there are no breaches, violations or defaults or allegations or assertions of such by any party thereunder, except for such breaches, violations, defaults, allegations or assertions that, individually or in the aggregate, would not result in a Material Adverse Effect.

(xlv) All of the information, as may have been updated or amended, provided to the Representative or to counsel for the Underwriters by the Company, its officers and directors in connection with letters, filings or other supplemental information provided to FINRA pursuant to FINRA Rule 5110 and FINRA Rule 5121 is true, complete and correct in all material respects.

Agreement. 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 Bank is duly qualified as a foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or to be in good standing would not reasonably be expected to result in a Material Adverse Effect. The activities of the Bank are permitted under the laws and regulations of the State of Louisiana and the deposit accounts in the Bank are insured up to the applicable limits by the FDIC and no proceeding for the termination or revocation of such insurance is pending or, to the knowledge of the Bank, threatened against the Bank.

(ii) The Bank is not in violation of its articles of incorporation or bylaws or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any indenture, mortgage, deed of trust, loan agreement, note, lease or other agreement or instrument to which it is a party or by which it or any of its properties may be bound or to which any of the property or assets of the Bank is subject except for such defaults that would not be expected to result in a Material Adverse Effect.

(c) Any certificate signed by an officer of the Company or the Bank and delivered to the Representative or to counsel for the Representative in connection with the offering of Shares shall be deemed to be a representation and warranty by the Company and/or the Bank to the Underwriters as to the matters set forth therein.

2. (a) Subject to the terms and conditions herein set forth, (i) the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters, agrees severally and not jointly, to purchase from the Company, at a purchase price per share of $13.09 (the “Purchase Price”) the Firm Shares as set forth in Schedule I hereto, and (ii) in the event and to the extent that the Underwriters shall exercise the election to purchase Optional Shares as provided below, the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at the Purchase Price, the Optional Shares. Subject to the terms and conditions herein set forth, the Company hereby grants to the Underwriters the right to purchase at their election up to 431,250 Optional Shares, at the Purchase Price, for the sole purpose of covering sales of shares in excess of the number of Firm Shares. Any such election to purchase Optional Shares may be exercised only by written notice from the Representative to the Company, given within a period of 30 calendar days after the date of this Agreement, setting forth the aggregate number of Optional Shares to be purchased, the number of Optional Shares to be purchased by the Underwriter and the date on which such Optional Shares are to be delivered, as determined by the Representative. 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.

(b) It is understood that 115,000 Firm Shares initially will be reserved by the Underwriters for offer and sale to the Directed Share Purchasers upon the terms and conditions set forth in the Prospectus and in accordance with the rules and regulations of FINRA. Subject to the terms and conditions herein set forth, (i) the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at the Purchase Price, the number of Directed Shares set forth opposite the name of such Underwriter in Schedule I. Under no circumstances will the Representative or any Underwriter be liable to the Company or to any Directed Share Purchaser for any action taken or omitted to be taken in good faith in connection with such Directed Share Program. Notwithstanding the foregoing, to the extent that any Directed Shares are not affirmatively reconfirmed for purchase by any Directed Share Purchaser listed on Schedule IV hereto on or immediately after the date of this Agreement (the “Unsold Directed Shares”), such Unsold Directed Shares may be offered by the Underwriters to the public as part of the public offering contemplated herein.

(c) It is understood that each Underwriter has authorized the Representative, for such Underwriter’s account, to accept delivery of, receipt for, and make payment of the purchase price for, the Firm Shares and the Optional Shares, if any, which such Underwriter has agreed to purchase. Sandler X’Xxxxx & Partners, L.P., individually and not as Representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Firm Shares or the Optional Shares, if any, to be purchased by any Underwriter whose funds have not been received by Sandler X’Xxxxx & Partners, L.P. by the relevant Date of Delivery but such payment shall not relieve such Underwriter from its obligations hereunder.

- 17 -

3. Upon the authorization by the Representative of the release of the Firm Shares, the several Underwriters propose to offer the Firm Shares for sale upon the terms and conditions set forth in the Prospectus.

4. (a) The Shares to be purchased by each Underwriter hereunder, in definitive form, and in such authorized denominations and registered in such names as the Representative may request upon at least forty-eight hours prior notice to the Company shall be delivered by or on behalf of the Company to the Representative, through the facilities of The Depository Trust Company (“DTC”), for the account of such Underwriter, against payment by or on behalf of such Underwriter of the purchase price therefor by wire transfer of Federal (same day) funds to the account specified by the Company, to the Representative at least forty-eight hours in advance. The time and date of such delivery and payment shall be, with respect to the Firm Shares, 10:00 A.M. (Eastern time) on July 3, 2014 (such time and date of payment and delivery being herein called “Closing Time”).

The documents to be delivered at Closing Time by or on behalf of the parties hereto, including the cross receipt for the Shares, will be delivered at the offices of Xxxxxxxxxx Xxxxxxxx & Xxxxxxxx LLP, 000 00^xx Xxxxxx, X.X., Xxxxx 000, Xxxxxxxxxx, X.X. 00000, or at such other place as shall be agreed upon by the Representative and the Company, at 10:00 A.M. (Eastern time) on July 3, 2014, or such other time and date as the Representative and the Company may agree upon in writing.

(b) In addition, in the event that any or all of the Optional Shares are purchased by the Underwriters, payment of the purchase price for such Optional Shares shall be made by wire transfer of Federal (same day) funds as set forth in Section 4(a) above and delivery of certificates for such Optional Shares 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.

5. The Company further covenants and agrees with each of the Underwriters as follows:

(a) The Company will prepare the Prospectus in a form approved by the Representative and file such Prospectus pursuant to Rule 424(b) under the 1933 Act not later than the Commission’s close of business on the second business day following the execution and delivery of this Agreement, or, if applicable, such earlier time as may be required by Rule 430A(a)(3) under the 1933 Act and will make no further amendment or any supplement to the Registration Statement or the Prospectus which shall be disapproved by the Representative promptly after reasonable notice thereof. The Company will advise the Representative, promptly after it receives notice thereof, of the time when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Prospectus or any amended Prospectus has been filed and furnish the Representative with copies thereof and will advise the Representative, promptly after it receives notice thereof, of the issuance by the Commission of any stop order with respect to the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, any Issuer-Represented Free Writing Prospectus, any Written Testing-the-Waters Communication or the Prospectus, of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, of the initiation or threatening of

- 18 -

any proceeding for any such purpose, or of any request by the Commission for the amending or supplementing of the Registration Statement, any preliminary prospectus, any Issuer-Represented Free Writing Prospectus, any Written Testing-the-Waters Communication or the Prospectus or for additional information, and, in the event of the issuance of any stop order or of any order preventing or suspending the use of any preliminary prospectus, any Issuer-Represented Free Writing Prospectus, any Written Testing-the-Waters Communication or Prospectus or suspending any such qualification, promptly use its best efforts to obtain the withdrawal of such order.

(b) 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, 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 Representative shall reasonably object.

(c) The Company has furnished or will deliver to the Representative and counsel for the Representative, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith) and signed copies of all consents and certificates of experts, and will also deliver to the Representative, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits). The copies of the Registration Statement and each amendment thereto furnished to the Representative 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) Promptly from time to time, the Company will take such action as the Representative may reasonably request to qualify the Shares for offering and sale under the securities laws of such states and other jurisdictions as the Representative 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 in connection therewith the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction. In each state or other 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 state or other jurisdiction to continue such qualification in effect until the completion of the distribution of the Shares. The Company will also supply the Representative with such information as is necessary for the determination of the legality of the Shares for investment under the laws of such jurisdiction as the Representative may reasonably request.

(e) Prior to 10:00 a.m., Eastern Time, on the New York Business Day next succeeding the date of this Agreement and from time to time, the Company will furnish the Underwriters with copies of the Prospectus in New York City in such quantities as the Representative may from time to time reasonably request, and, if the delivery of a prospectus is required at any time prior to the expiration of nine months after the time of issue of the Prospectus

- 19 -

in connection with the offering or sale of the Shares and if at such time any event shall have occurred as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made when such Prospectus is delivered, not misleading, or, if for any other reason it shall be necessary during such period to amend or supplement the Prospectus in order to comply with the 1933 Act, notify the Representative and upon the Representative’s request prepare and furnish without charge to each Underwriter and to any dealer in securities as many copies as the Representative may from time to time reasonably request of an amended Prospectus or a supplement to the Prospectus which will correct such statement or omission or effect such compliance, and in case any Underwriter is required to deliver a prospectus in connection with sales of any of the Shares at any time nine months or more after the time of issue of the Prospectus, upon such Underwriter’s request but at the expense of such Underwriter, prepare and deliver to such Underwriter as many copies as it may request of an amended or supplemented Prospectus complying with Section 10(a)(3) of the 1933 Act.

(f) 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 Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Shares, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Representative or for the Company, to amend the Registration Statement or 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 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 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 5(b), 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 the Company will furnish to the Representative such number of copies of such amendment or supplement as the Representative 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 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.

(g) The Company will make generally available to its securityholders as soon as practicable, an earnings statement of the Company and its subsidiary (which need not be audited) complying with Section 11(a) of the 1933 Act and the 1933 Act Regulations (including, at the option of the Company, Rule 158).

The foregoing sentence shall not apply to (A) the Shares to be sold hereunder or (B) any shares of common stock issued by the Company (i) upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and reflected in the Registration Statement, the General Disclosure Package and the Prospectus or (ii) upon the exercise of an option or warrant or the conversion of a security issued after the date of this Agreement. If the Representative, in its sole discretion, agrees to release or waive the restrictions set forth in a lock-up agreement executed and delivered under Section 1(a)(xlii) for an executive officer or director of the Company and the Representative 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, upon the Representative’s request, the Company agrees to announce or cause to be announced the impending release or waiver by a press release substantially in the form of Exhibit B hereto through a major news service at least two business days before the effective date of the release or waiver.

7. The obligations of the Underwriters hereunder to purchase and pay for the Shares as provided herein on the Closing Time and, with respect to the Optional Shares, each additional Date of Delivery, shall be subject, in its discretion, to the condition that all representations and warranties and other statements of the Company herein are, at and as of such Closing Time and, with respect to the Optional Shares, at and as of each Date of Delivery, true and correct, the condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

- 23 -

(a) The Prospectus shall have been filed with the Commission pursuant to Rule 424(b) within the applicable time period prescribed for such filing by the rules and regulations under the 1933 Act and in accordance with Section 5(a) hereof (or a post-effective amendment shall have been filed and declared effective in accordance with the requirements of Rule 430A), if the Company has elected to rely upon Rule 462(b), the Rule 462(b) Registration Statement shall have become effective by 4:00 p.m., Eastern Time, on the date of this Agreement, no stop order suspending the effectiveness of the Registration Statement or any part thereof shall have been issued and no proceeding for that purpose shall have been initiated or threatened by the Commission, and all requests for additional information on the part of the Commission shall have been complied with to your reasonable satisfaction, and FINRA shall have raised no objection to the fairness and reasonableness of the underwriting terms and arrangements.

(e) No event or condition of a type described in Section 1(a)(viii) shall have occurred or shall exist, otherwise than as set forth or contemplated in the General Disclosure Package and the Prospectus, the effect of which is in the judgment of the Representative so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares being delivered at the Closing Time and, with respect to the Optional Shares, each additional Date of Delivery on the terms and in the manner contemplated in the Prospectus.

(g) The Shares have been approved for listing, subject to official notice of issuance and evidence of satisfactory distribution, on the Nasdaq Global Market.

If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representative by notice to the Company at any time on or prior to the Closing Time. If the sale of the Shares provided for herein is not consummated because any condition set forth in this Section 7 is not satisfied, because of any

- 25 -

termination pursuant to Section 11(a) hereof, or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will reimburse the Underwriters through the Representative upon demand for all documented out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by the Underwriters in connection with the proposed offering of the Shares. In addition, such termination shall be subject to Section 6 hereof, and Sections 1, 8 and 10 hereof shall survive any such termination and remain in full force and effect.

8. (a) The Company and the Bank, jointly and severally, will indemnify and hold harmless each Underwriter, each person, if any, who controls such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and their respective partners, directors, officers, employees and agents against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any breach or violation by the Company of Section 5(o) hereof or (ii) an untrue statement or alleged untrue statement of a material fact contained in any Issuer-Represented Free Writing Prospectus, any Written Testing-the-Waters Communications, any preliminary prospectus, the Registration Statement, the General Disclosure Package, the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Underwriters for any legal or other expenses reasonably incurred by the Underwriters in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company and the Bank shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Issuer-Represented Free Writing Prospectus, any Written Testing-the-Waters Communications, any preliminary prospectus, the Registration Statement, the General Disclosure Package, the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by an Underwriter through the Representative expressly for use therein. The Company, the Bank and the Underwriters hereby acknowledge and agree that the only information that the Underwriters have furnished to the Company consists solely of the information described as such in subsection (b) below. Notwithstanding the foregoing, the indemnification provided for by the Bank in this paragraph 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 this indemnification would result in an adverse impact on the Bank’s examination ratings, (c) such indemnification would give rise to civil money penalties or other sanctions or (d) the Bank determines, upon the written advice of counsel, that payment of any indemnification hereunder by the Bank would violate any law, rule, regulation or policy applicable to the Bank or the Company. The Company and the Bank agree to notify the Representative immediately upon receipt of such written advisement or notice. The Underwriters agree to cooperate with the Company in implementing any modification required by the foregoing.

- 26 -

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, its officers, directors 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 losses, claims, damages or liabilities to which the Company may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Issuer-Represented Free Writing Prospectus, any Written Testing-the-Waters Communications, any preliminary prospectus, the Registration Statement, the General Disclosure Package or the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Issuer-Represented Free Writing Prospectus, any Written Testing-the-Waters Communications, preliminary prospectus, the Registration Statement, the General Disclosure Package or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by the Underwriters expressly for use therein and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. The Company and the Underwriters hereby acknowledge and agree that the only information that the Underwriters have furnished to the Company specifically for inclusion in any Issuer-Represented Free Writing Prospectus, any Written Testing-the-Waters Communications, any preliminary prospectus, the Registration Statement, the General Disclosure Package or the Prospectus, or any amendment or supplement thereto, is (i) the allocation, concession and discount figures appearing in the Prospectus in the section entitled “Underwriting” (ii) the Underwriters reservation of the right to withdraw, cancel or modify the offer contemplated by this Agreement and to reject orders in whole or in part, as described in the Prospectus under the section entitled “Underwriting” and (iii) the affecting of stabilization transactions, overallotment transactions, syndicate covering transactions and, if applicable, penalty bids in which the Underwriters may engage, as described in the Prospectus in the section entitled “Underwriting” (collectively, the “Underwriters’ Information”).

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection, unless the indemnifying party has been prejudiced thereby. 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 (who shall not, except with the consent of the indemnified party which consent shall not be unreasonably withheld, 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

- 27 -

which are 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 such legal defenses 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, and, 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 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 one counsel for the indemnified party or parties (in addition to local counsel) shall be at the expense of the indemnifying party. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceedings effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8(c), the indemnifying party agrees that it shall be liable for any settlement of any proceeding 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 the indemnified party in accordance with such request (other than those fees and expenses that are being contested in good faith) prior to the date of such settlement. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action 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) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) 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 from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in

- 28 -

such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), 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 shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other 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 contributions pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public 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 8, each officer and employee of an Underwriter and each person, if any, who controls such Underwriter within the meaning of the 1933 Act and the 1934 Act 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 with the meaning of the 1933 Act and the 1934 Act shall have the same rights to contribution as the Company. Notwithstanding the foregoing, the contribution obligation of the Bank in this paragraph 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 any contribution would result in an adverse impact on the Bank’s examination ratings, (c) such contribution would give rise to civil money penalties or other sanctions or (d) the Bank determines, upon the written advice of counsel, that any contribution made by the Bank hereunder would violate any law, rule, regulation or policy applicable to the Bank or the Company.

(e) In connection with the offer and sale of Directed Shares, the Company agrees promptly upon written notice, to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities

- 29 -

Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, liabilities, claims, damages and expenses incurred by them as a result of the violation of any applicable laws or regulations of any foreign jurisdictions where Directed Shares have been offered. Under no circumstances will the Representative or any Underwriter be liable to the Company or to any Directed Share Purchaser for any action taken or omitted to be taken in good faith in connection with the Directed Shares or any transaction effected with any Directed Share Purchaser.

(f) The obligations of the Company and the Bank under this Section 8 shall be in addition to any liability which the Company and the Bank may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls (within the meaning of the 0000 Xxx) any Underwriter, or any of the respective partners, directors, officers and employees of any Underwriter or any such controlling person.

(g) The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to an indemnified party at law or in equity.

9. (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at a Date of Delivery, the Representative may in its discretion arrange for it or another party or other parties reasonably satisfactory to the Company to purchase such Shares on the terms contained herein. If within 36 hours after such default by any Underwriter, the Representative does not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of 36 hours within which to procure another party or other parties reasonably satisfactory to the Representative to purchase such Shares on such terms. In the event that, within the respective prescribed periods, the Representative notifies the Company that it has so arranged for the purchase of such Shares, or the Company notifies the Representative that it has so arranged for the purchase of such Shares, the Representative or the Company shall have the right to postpone such Date of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement, the General Disclosure Package or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which the Representative may determine to be made necessary thereby. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representative and the Company as provided in Section 9(a) above, the aggregate number of such Shares which remains unpurchased does not exceed one tenth of the aggregate number of all the Shares to be purchased at such Date of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of shares which such Underwriter agreed to purchase hereunder at such Date of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

- 30 -

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representative and the Company as provided in Section 9(a) above, the aggregate number of such Shares which remains unpurchased exceeds one tenth of the aggregate number of all the Shares to be purchased at such Date of Delivery, or if the Company shall not exercise the right described in Section 9(b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Shares.

11. (a) The Representative may terminate this Agreement, by notice to the Company, at any time on or prior to the Closing Time if, since the time of execution of this Agreement or, in the case of (i) below, since the date of the most recent balance sheets included in the Financial Statements, there has occurred, (i) any Material Adverse Effect, (ii) a suspension or material limitation in trading in the Company’s securities on Nasdaq, (iii) a general moratorium on commercial banking activities declared by either Federal, New York or Louisiana authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States, (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, including without limitation, as a result of terrorist activities occurring after the date hereof, if the effect of any such event specified in clause (iv) or (v), in the reasonable judgment of the Representative is so material and adverse so as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares being delivered at the Closing Time and, with respect to the Optional Shares, each additional Date of Delivery on the terms and in the manner contemplated in the Prospectus.

(b) If this Agreement is terminated pursuant to this Section 11, such termination shall be without liability of any party to any other party except as provided in Section 6 hereof and provided further that Sections 1, 8 and 10 hereof shall survive such termination and remain in full force and effect.

12. 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.

13. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Representative shall be delivered or sent by mail or overnight delivery service or facsimile
