2008 STOCK INCENTIVE PLAN

THIS AGREEMENT entered into as of, between IBERIABANK Corporation (“IBKC” or the “Company”) and                                          (“Optionee”) (the “Agreement”), in accordance with the terms of the IBERIABANK Corporation 2008 Stock Incentive Plan (the “Plan”). Capitalized terms shall have the same meaning as set forth in the Plan, unless the context clearly indicates otherwise.

1. Grant of Option

1.1 IBKC hereby grants to Optionee effective                          (the “Date of Grant”), the option to purchase up to                          shares of Common Stock (the “Option”) at an exercise price of $ per share (the “Exercise Price”). ⁽¹⁾ The Option shall vest, become exercisable and expire as provided in Section 2 below.

1.2 The Option is intended to be treated as an incentive stock option (an “ISO”) under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), unless designated herein as a non-qualified stock option (a “Non-ISO”). If the Option is designated as an ISO and is not eligible for such treatment, the ineligible portion shall be treated as a Non-ISO.

2. Time of Exercise

2.1 Subject to the provisions of the Plan and this Agreement, the Optionee shall be entitled to exercise the Option as follows:

2.2 The Option shall expire and may not be exercised later than ten years following the Date of Grant.

2.3 Notwithstanding the foregoing, the Option shall become accelerated and immediately exercisable in the event of Optionee’s termination of employment as a result of death or disability and in the event of a Change in Control as provided in Section 13(c) of the Plan.

2.4 The Option shall be exercised in the manner set forth in the Plan, using the exercise form attached hereto as Exhibit A. The exercise price may be paid in cash, check, Shares or through a cashless exercise program through a broker, all on the terms provided in the Plan.

3. Conditions for Exercise of Option

3.1 During Optionee’s lifetime, the Option may be exercised only by the Optionee or by the Optionee’s guardian or legal representative. The Option must be exercised while Optionee is employed by IBKC, or in the event of a termination of employment, for such period following termination under certain circumstances, as may be provided in Section 6(h) of the Plan. Notwithstanding the foregoing, no Option may be exercised more than ten years following the Date of Grant.

3.2 In the event the Optionee is discharged from the employ of IBKC or a subsidiary company for Cause, as defined in the Plan, the Optionee shall forfeit the right to exercise any portion of this Option, which shall be immediately null and void.

4. Additional Conditions

Anything in this Agreement to the contrary notwithstanding, if at any time IBKC further determines, in its sole discretion, that the listing, registration or qualification (or any updating of any such document) of the shares of Common Stock issuable pursuant to the exercise of an Option is necessary on any securities exchange or under any federal or state securities or blue sky law, or that the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with the issuance of shares of Common Stock pursuant thereto, or the removal of any restrictions imposed on such shares, such shares of Common Stock shall not be issued, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to IBKC.

5. Taxes

5.1 IBKC may make such provisions as it may deem appropriate for the withholding of any federal, state and local taxes that it determines are required to be withheld on the exercise of the Option. By signing this Option, the Optionee agrees that he or she is solely responsible for the satisfaction of any taxes that may arise (including taxes arising under Sections 409A or 4999 of the Code) and that IBKC shall not have any obligation whatsoever to pay such taxes.

5.2 Optionee may, but is not required to, satisfy his or her withholding tax obligation in whole or in part by electing (the “Election”) to have IBKC withhold, from the Shares he or she otherwise would receive upon exercise of the Option, Shares of Common Stock having a value equal to the minimum amount required to be withheld. The value of the Shares to be withheld shall be based on the Fair Market Value of the Common Stock on the date that the amount of tax to be withheld shall be determined (the “Tax Date”). Each Election must be made prior to the Tax Date. The Committee may disapprove of any Election or may suspend or terminate the right to make Elections, except that, notwithstanding the terms of the Plan, if the Optionee is an Executive Officer or is otherwise subject to Section 16 of the Securities Exchange Act of 1934, as amended, the right to make an Election may not be disapproved, terminated or suspended. In the absence of any other arrangement, an Optionee who is an Executive Officer will be deemed to have elected to have Shares withheld to satisfy withholding taxes as provided herein.
