2.2 Conversion of PIC Common Stock.

(a) As used herein, the term “Total Merger Consideration” shall mean: (i) a number of shares of IBKC Common Stock with a total market value of $32.5 million based upon the trading price of IBKC Common Stock applicable to the Fixed Exchange Ratio ($58.60 per share);plus (ii) a number of shares of IBKC Common Stock with a total Market Value of $32.5 million based upon the trading prices of IBKC Common Stock to be applicable to the Floating Exchange Ratio; plus (iii) cash (without interest) in the total amount of $65.0 million, subject to adjustment under Sections 7.8 and 8.7 of this Agreement.

- 4 -

(b) Except for shares of PIC Common Stock as to which dissenters’ rights have been perfected and not withdrawn or otherwise forfeited (“Dissenters’ Shares”) under the ABCA, and as otherwise provided herein, at the Effective Date each issued and outstanding share of PIC Common Stock will be converted into the “ Per Share Merger Consideration” which shall mean:

(i) shares of IBKC Common Stock based upon the Fixed Exchange Ratio; plus

(ii) shares of IBKC Common Stock based upon the Floating Exchange Ratio; plus

(iii) an amount of cash (without interest) determined by dividing $65.0 million by the number of shares of PIC Common Stock outstanding on the Effective Date (rounded to the nearest whole cent).

(c) Shares of PIC Common Stock that are held by PIC and any PIC Subsidiary (other than shares held in a fiduciary capacity) shall not be considered to be outstanding and shall be cancelled (and not converted) by virtue of the Merger at the Effective Date and without any further action by any party.

(d) If, before the Effective Date, IBKC should split, reclassify, recapitalize or combine the IBKC Common Stock, or pay a stock dividend in IBKC Common Stock, or otherwise change the IBKC Common Stock into any other securities, or make any other dividend or distribution in respect of the IBKC Common Stock (other than normal cash dividends consistent with past practices as the same may be adjusted from time to time in accordance with or not in violation of this Agreement), and the record date therefore is prior to the Effective Date, then the Exchange Ratios will be appropriately and proportionately adjusted to reflect such split, reclassification, recapitalization, combination, stock dividend or other distribution or change.

(e) In lieu of issuing any fractional share of IBKC Common Stock which would otherwise be distributable to a PIC stockholder as determined following application of Section 2.2(a), each holder of PIC Common Stock who would otherwise be entitled thereto, after aggregating into whole shares all fractional shares of IBKC Common Stock to which such holder is entitled by virtue of the Merger, upon surrender of the certificate(s) which represented PIC Common Stock, will receive, without interest, cash equal to such fractional share multiplied by $58.60.

(f) No later than the Effective Date, IBKC shall deposit, or shall cause to be deposited, with the Exchange Agent for the benefit of the holders of PIC Common Stock, for exchange in accordance with this Section 2.2, certificates and cash (in immediately available funds) representing the Total Merger Consideration to be paid. After the Effective Date, each holder of PIC Common Stock (other than Dissenters’ Shares), upon surrender of such holder’s Certificates in accordance herewith, will be entitled to receive the shares of IBKC Common Stock and cash into which such holder’s shares have been converted, less any applicable tax withholding. Until then, each Certificate for PIC Common Stock will represent the Per Share Merger Consideration into which the shares of PIC Common Stock represented thereby were converted, except that IBKC may refuse to pay any dividend or other distribution payable to holders of any unsurrendered Certificate for PIC Common Stock (without any interest thereon) until surrender or if such dividend or distribution has reverted in full ownership to IBKC under its Articles of Incorporation. Whether or not a Certificate for PIC Common Stock is surrendered, after the Effective Date it will not represent any interest in any Person other than IBKC.

(g) Prior to the Effective Date, IBKC or the Exchange Agent shall mail to each holder of record of a Certificate or Certificates a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Certificates in exchange for the Per Share Merger Consideration into which the shares of PIC Common Stock represented by such Certificate or Certificates shall have been converted pursuant to this Section 2.2. Upon proper surrender of a Certificate for exchange and cancellation to the Exchange Agent, together with a properly completed letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefore (i) a certificate representing that number of shares of IBKC Common Stock to which such former holder of PIC Common Stock shall have become entitled pursuant to this Agreement and (ii) a check (or, as provided in Section 2.2(h) below, wire transfer of immediately available funds) representing that amount of cash to which such former holder of PIC Common Stock shall have become entitled pursuant to this Agreement.

- 5 -

(h) IBKC and the Exchange Agent shall within one (1) Business Day after the Effective Date wire the cash amount of the Per Share Merger Consideration and deliver by overnight courier certificates for shares of IBKC Common Stock to any former holders of PIC Common Stock who request such payment and have properly surrendered Certificates in exchange for the Merger Consideration prior to the Effective Date.

(j) If the Person surrendering a Certificate and signing the accompanying letter of transmittal is not the record holder thereof, then it shall be a condition of the payment of the Per Share Merger Consideration that: (i) such Certificate is properly endorsed to such Person or is accompanied by appropriate stock powers, in either case signed exactly as the name of the record holder appears on such Certificate, and is otherwise in proper form for transfer, or is accompanied by appropriate evidence of the authority of the Person surrendering such Certificate and signing the letter of transmittal to do so on behalf of the record holder; and (ii) the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar taxes required by reason of the payment to a Person other than the registered holder of the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

(c) PIC will, for total premiums not to exceed $161,000 (the “Maximum Amount”), purchase a continuation of their current directors and officers liability insurance for a coverage period of three (3) years after the Merger, provided that if the amount of the annual premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, IBKC shall maintain the most advantageous policies of directors’ and officers’ insurance obtainable for an annual premium equal to the Maximum Amount.

(a) Subject to Section 6.9(d) of this Agreement, PIC agrees that, from the date of this Agreement until the earlier of the Effective Date or the termination of this Agreement, neither it nor any of its affiliates, nor any of the officers and directors of it or its affiliates shall, and that it shall cause its and its affiliates’ employees, agents and representatives (including any investment banker, attorney or accountant retained by it or any of its affiliates) not to, directly or indirectly, (i) initiate, solicit, encourage or knowingly facilitate any inquiries or the making of any Acquisition Proposal, (ii) have any discussion with or provide any confidential information or data to any Person relating to an Acquisition Proposal, or engage in any negotiations concerning an Acquisition Proposal, or knowingly facilitate any effort or attempt to make or implement an Acquisition Proposal, (iii) approve or recommend, or propose publicly to approve or recommend, any Acquisition Proposal or (iv) approve or recommend, or propose to approve or recommend, or execute or enter into any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement or propose publicly or agree to do any of the foregoing related to any Acquisition Proposal.

(b) PIC agrees that it will, and will cause its officers, directors and representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations existing as of the date of this Agreement with any parties conducted heretofore with respect to any Acquisition Proposal informing them that the Board of Directors no longer seeks the making of any Acquisition Proposals.

(c) PIC agrees that it will use reasonable best efforts to promptly inform its directors, officers, key employees, agents and representatives of the obligations undertaken in this Section 6.9.

(d) Notwithstanding the provisions of Section 6.9(a) of this Agreement, if any Person after the date of this Agreement submits to PIC’s board of directors an unsolicited, bona fide, written Acquisition Proposal, and PIC’s board of directors reasonably determines in good faith, after receipt of advice from outside legal counsel, that the failure to engage in discussions with such Person concerning such Acquisition Proposal may cause PIC’s board of directors to breach its fiduciary duties to PIC and its stockholders, and after consultation with its financial advisor, then, in such case, (i) PIC may (A) furnish information about its business to such Person under protection of an appropriate confidentiality agreement containing customary limitations on the use and disclosure of all non-public written or oral information furnished to such Person, provided that PIC must contemporaneously furnish to IBKC all such non-public information furnished to such Person, and (B) negotiate and participate in discussions and negotiations with such Person; and (ii) if PIC’s board of directors determines that such an Acquisition Proposal is a Superior Proposal (defined below), PIC’s board of directors may (subject to the provisions of this Section 6.9) (A) withdraw or adversely modify its approval or recommendation of the Merger and recommend such Superior Proposal or (B) terminate this Agreement, in each case, (i) at any time after five (5) Business Days following IBKC’c receipt of written notice (a “Notice of Superior Proposal”) advising IBKC that PIC’s board of directors has received a Superior Proposal and enclosing a copy of the Acquisition Proposal, identifying the Person submitting the Superior Proposal, specifying the material terms and conditions of such Superior Proposal, and (ii) subject to IBKC’s Right of First Refusal (defined below). In the event IBKC elects not to exercise the Right of First Refusal, PIC shall provide IBKC with a final written notice of acceptance before or simultaneous with accepting any Superior Proposal. For purposes of this Agreement, “Superior Proposal” means any unsolicited, bona fide, written Acquisition Proposal for consideration consisting of cash and/or securities, and otherwise on terms which PIC’s board of directors determines, after consultation with its financial advisor, are more favorable to PIC’s stockholders (in their capacities as stockholders) from a financial point of view than the Merger after giving effect to the provisions of Section 9.2 (or other revised proposal submitted by IBKC). For the purposes of this Section 6.9(d), an Acquisition Proposal shall be “bona fide” if the board of directors of PIC reasonably determines that the Person submitting such Acquisition Proposal is capable, from a financial, regulatory and other appropriate perspectives, of consummating such Acquisition Proposal on the terms proposed.

(e) IBKC shall have the right (“Right of First Refusal”) for five (5) Business Days after receipt of Notice of Superior Proposal to make such adjustments in the terms and conditions of this Agreement as would enable PIC to proceed with the Merger on the basis of such adjusted terms. If IBKC fails to exercise such Right of First Refusal within the time herein specified, PIC shall be at liberty to accept the Superior Proposal, subject to the obligations of PIC pursuant to Section 9.2 hereof.

EXHIBIT I

AGREEMENT OF MERGER

THIS AGREEMENT OF MERGER (“Agreement”) is made as of                     , 2006, between IBERIABANK Corporation (“IBKC”) and Pulaski Investment Corporation (“PIC”), in connection with the Agreement and Plan of Merger, dated as of August     , 2006 (the “Plan”), between IBERIABANK Acquisition Corporation (“IBAC”) and IBERIABANK Corporation on the one hand and PIC on the other. Capitalized terms not defined herein shall have their respective meanings set forth in the Plan.

ARTICLE 1: TERMS OF MERGER

1.1 Merger. Subject to the terms and conditions hereof, at the Effective Date (defined herein), PIC shall be merged with and into IBAC (the “Merger”), in accordance with, and with the effect provided in, the Louisiana Business Corporation Law (the “BCL”) and the Arkansas Business Corporation Act (the “ABCA”).

1.2 Assumption of Rights and Liabilities. At the Effective Date and thereafter, all the rights and property, real, personal, and mixed, of PIC, shall be deemed to be transferred to and vested in IBAC without further act or deed; and the title to any real estate, or any interest therein, vested in IBAC shall not revert or be in any way impaired by reason of the Merger. All liabilities and obligations of PIC of every kind and description shall be assumed by IBKC, and IBKC shall be bound thereby in the same manner and to the same extent that PIC was so bound at the Effective Date.

ARTICLE 2: MANNER OF CONVERTING SHARES

2.1 Conversion of PIC Common Stock.

(a) Except for shares of PIC Common Stock as to which dissenters’ shares have been perfected and not withdrawn or otherwise forfeited (“Dissenters’ Shares”) under the ABCA, and as otherwise provided herein and in the Plan, at the Effective Date each outstanding share of PIC Common Stock will be converted into the “Per Share Merger Consideration” which shall mean:

(i) .2274 shares of IBKC Common Stock (to the nearest ten-thousandth of a share); plus

(ii) a number of shares of IBKC Common Stock equal to the quotient (rounded to the nearest ten-thousandth of a share) obtained by dividing $13.323 by the average of the daily average trading prices of the IBKC Common Stock on the NASDAQ Global Market (or calculated by Bloomberg Screen AQR) on each of the fifteen (15) trading days ending one (1) Business Day prior to the Effective Date; plus

(iii) an amount of cash (without interest) determined by dividing $65.0 million by the number of shares of PIC Common Stock outstanding on the Effective Date (rounded to the nearest whole cent). No payments or benefits to officers of PIC or its Subsidiaries in connection with the Merger shall constitute an excess parachute payment

under Section 280G of the Code (or, if so, PIC may satisfy this condition by reducing such total cash payment by an amount equal to the additional income tax incurred by PIC and its Subsidiaries as a result of the disallowance of the deduction applicable thereto).

(b) Shares of PIC Common Stock that are held by PIC and any PIC subsidiary (other than shares held in a fiduciary capacity) shall not be considered to be outstanding and shall be cancelled (and not converted) by virtue of the Merger at the Effective Time and without any further action by any party.

(c) If before the Effective Date, IBKC should split or combine the IBKC Common Stock, or pay a stock dividend in IBKC Common Stock, or otherwise change the IBKC Common Stock into any other securities, or make any other dividend or distribution in respect of the IBKC Common Stock (other than normal cash dividends as the same may be adjusted from time to time in accordance with or not in violation of this Agreement), then the Exchange Ratio will be appropriately adjusted to reflect such split, combination, dividend or other distribution or change.

(d) In lieu of issuing any fractional share of IBKC Common Stock, each holder of PIC Common Stock who would otherwise be entitled thereto, after aggregating into whole shares all fractional shares of IBKC Common Stock to which such holder is entitled by virtue of the Merger, upon surrender of the certificate(s) which represented PIC Common Stock, will receive cash (without interest) equal to such fractional share multiplied by $58.60.

(e) No later than the Effective Date, IBKC shall deposit, or shall cause to be deposited, with IBKC’s transfer agent, or such other third party experienced in the stock transfer business reasonably acceptable to PIC which shall act as an exchange agent, for the benefit of the holders of PIC Common Stock, for exchange in accordance with this Section 2.1 and the Plan, certificates representing shares of IBKC Common Stock and the estimated amount of cash to be paid to the holders of PIC Common Stock. After the Effective Date, each holder of PIC Common Stock (other than Dissenters’ Shares), upon surrender of such holder’s certificates in accordance herewith, will be entitled to receive the Per Share Merger Consolidation into which such holder’s shares have been converted, less any applicable tax withholding. Until then, each certificate for PIC Common Stock will represent the Per Share Merger Consideration into which the shares of PIC Common Stock represented thereby were converted, except that IBKC may refuse to pay any dividend or other distribution payable to holders of any unsurrendered certificate for PIC Common Stock (without any interest thereon) until surrender or if such dividend or distribution has reverted in full ownership to IBKC under its Articles of Incorporation. Whether or not a certificate for PIC Common Stock is surrendered, after the Effective Date it will not represent any interest in any person other than IBKC.

ARTICLE 3: EFFECTIVENESS

3.1 Effectiveness. Consummation of the Merger is conditioned upon the approval of this Agreement by the Board of Governors of the Federal Reserve System and necessary filings with the Louisiana Secretary of State and the Arkansas Secretary of State, and the other conditions set forth in the Plan. The Merger shall become effective on the date and at the time this Agreement is filed with the Secretary of State of Louisiana and the Secretary of State of Arkansas (the “Effective Date”).

2

3.2 Additional Actions. If, after the Effective Date, IBAC shall believe any act to be necessary or desirable to carry out the purposes of this Agreement, PIC and its proper officers and directors shall be deemed to have granted to IBKC an irrevocable power of attorney to do any such act, and the proper officers and directors of IBKC are fully authorized in the name of PIC to take any and all such action.

ARTICLE 4: MISCELLANEOUS

4.1 Amendment. This Agreement or any exhibit or schedule may be amended or restated at any time by (i) the parties, by mutual agreement approved by their Boards, except that the consideration to stockholders of PIC shall not be amended after approval of the Plan by PIC’s stockholders or (ii) by the parties’ chief executive officers or their designees to correct typographical errors or to change erroneous references or cross references, or in any other manner not material to the substance of the Merger; provided, however, that no amendment shall be effective unless reduced to writing and executed by all parties to this Agreement. The waiver by any party hereto of a breach of or noncompliance with any provision of this Agreement will not operate or be construed as a continuing waiver or a waiver or any other or subsequent breach or noncompliance hereunder.

4.2 Termination. Prior to the Effective Date, this Agreement may be terminated, and the Merger abandoned, as set forth in the Plan, and shall terminate on any termination of the Plan.

4.3 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument.

4.4 Governing Law. This Agreement shall be governed by, and interpreted in accordance with, the laws of the State of Louisiana applicable to contracts made and to be performed wholly within such State (except to the extent that mandatory provisions of Federal law are applicable).
