Section 6. Payment of Awards.

Performance Awards for a given Plan Year shall be paid in cash as soon as practicable following the certification by the Committee of the attainment of the Performance Measures.

Section 8. Change in Control.

Unless otherwise provided in a written agreement between the Company and a Participant, if a Change in Control occurs, then the Performance Measures and the Performance Award shall be automatically adjusted on a pro-rata basis (generally, based on the number of days in the Plan Year through the date of the Change in Control, divided by the number of total days in the Plan Year), and to reflect the time value of money. If the Committee, in its discretion, established minimum, target and maximum levels of Performance Measures and the related Performance Awards for such Plan Year, then the automatic adjustment described in this section shall apply to each such level. The Committee shall have the discretion to (i) certify whether each Participant has attained the Performance Measures (as adjusted) as of the date of the Change in Control or (ii) approve the payment of the Performance Award at the target level. Notwithstanding Section 6 above, and except as otherwise provided under any written agreement between the Company and a Participant, each Participant shall receive a lump sum cash payment of any Performance Award (as adjusted) to which he or she is entitled under this section, no later than thirty (30) days following the closing of the Change in Control,.

ended without the consent of each Participant whose rights under his or her Performance Award would be impaired by such amendment, modification or termination.

Section 13. General Provisions.

13.1 Unfunded Plan. The Plan shall be an unfunded incentive compensation arrangement for a select group of key management employees of the Company. Nothing contained in the Plan, and no action taken pursuant to the Plan, shall create or be construed to create a trust of any kind. A Participant’s right to receive a Performance Award shall be no greater than the right of an unsecured general creditor of the Company. All Performance Awards shall be paid from the general funds of the Company, and no segregation of assets shall be made to ensure payment of Performance Awards.

13.2 Governing Law. The Plan shall be interpreted, construed and administered in accordance with the laws of the State of Alabama, without giving effect to principles of conflicts of law.

13.3 Section Headings. The section headings contained in the Plan are for purposes of convenience only and are not intended to define or limit the contents of the Plan’s sections.

13.4 Effect on Employment. Nothing contained in the Plan shall affect or be construed as affecting the terms of employment of any Eligible Employee except as expressly provided in the Plan. Nothing in the Plan shall affect or be construed as affecting the right of the Company to terminate the employment of an Eligible Employee at any time for any reason, with or without cause.

13.5 No Limitation to Corporate Action. Nothing in the Plan shall preclude the Company from authorizing the payment to the Eligible Employees of other compensation, including (without limitation) base salaries, awards under any other plan of the Company or its Affiliates, any other incentive payments or bonuses (whether or not based on the attainment of performance objectives) and retention or other special payments.

13.6 Successors. All obligations of the Company with respect to Performance Awards granted under the Plan shall be binding upon any successor to the Company, whether such successor is the result of an acquisition of stock or assets of the Company, a merger, a consolidation or otherwise.

13.8 Withholding of Taxes. The Company shall deduct from each Performance Award the amount of any taxes required to be withheld by any federal, state or local governmental authority.

13.9 Severability. If any provision of the Plan is held unenforceable, the remainder of the Plan shall continue in full force and effect without regard to such unenforceable provision and shall be applied as though the unenforceable provision were not contained in the Plan.

13.10 Other Written Agreements. In the event of a conflict between the material terms and conditions of this Plan and the material terms and conditions of a Participant’s written employment agreement or other similar written agreement with the Company (if applicable), the terms and conditions of the Participant’s employment or other similar agreement will control.

13.11 Section 409A. The compensation and benefits payable pursuant this Plan are intended to be exempt from, or comply with, as applicable, the requirements of Internal Revenue Code Section 409A and Department of Treasury regulations and other interpretative guidance issued thereunder, including without limitation any such regulations or other such guidance that may be issued after the Effective Date (collectively, “Section 409A”)). To the extent applicable, this Plan and any applicable written agreement related to the payments hereunder shall be interpreted in accordance with Section 409A. Notwithstanding any other provision of this Plan to the contrary, if a Participant is a “specified employee” within the meaning of Section 409A, and a payment or benefit provided hereunder would be subject to additional tax under Section 409A if such payment or benefit is paid within six (6) months after the Participant’s “separation from service” (within the meaning of Section 409A), then such payment or benefit required under this Plan shall not be paid (or commence) during the six-month period immediately following the Participant’s separation from service. If the payment of any such amount is delayed in accordance with the previous sentence, then any payments or benefits that would otherwise have been made or provided during such six-month period and which would have incurred such additional tax under Section 409A shall instead be paid to the Participant in a lump-sum cash payment on the first regular payroll date of the seventh month following the Participant’s separation from service or such earlier date upon which such amount can be paid under Section 409A

without resulting in a prohibited distribution, including as a result of the Participant’s death). If the Participant’s termination of employment hereunder does not constitute a “separation from service” within the meaning of Section 409A, then any amounts payable hereunder on account of a termination of the Participant’s employment and which are subject to Section 409A (or any exemption therefrom that requires the occurrence of a “separation from service” as a condition to payment) shall not be paid until the Participant has experienced a “separation from service” within the meaning of Section 409A. Notwithstanding any provision of this Plan to the contrary, in the event that the Company determines that any compensation or benefits payable under this Plan may be subject to Section 409A, the Company and the Participant shall cooperate in good faith to adopt such amendments to this Plan or any applicable written agreement between the Company and the Participant related thereto or adopt other policies or procedures (including amendments, policies and procedures with retroactive effect), or take any other actions that the Company determines are reasonably necessary or appropriate to preserve the intended tax treatment of the compensation and benefits payable hereunder, including without limitation actions intended to (i) exempt the compensation and benefits payable hereunder from Section 409A, and/or (ii) comply with the requirements of Section 409A, provided, that this Section 13.11 does not, and shall not be construed so as to, create any obligation on the part of the Company to adopt any such amendments, policies or procedures or to take any other such actions. Notwithstanding anything herein to the contrary, neither the Company nor any of its affiliates shall have any liability to the Participant or to any other person if the payments and benefits provided hereunder that are intended to be exempt from, or compliant with, Section 409A are not so exempt or compliant or for any taxes, interest or penalties imposed under Section 409A or any corresponding provision of state or local law. Each payment payable hereunder in series of installments, including without limitation any severance payments or benefits, shall be treated as a separate payment in a series of payments within the meaning of, and for purposes of, Section 409A.
