15.

Section 409A.

(a)

The Company acknowledges that the Executive is a “specified employee” as defined and applied in Section 409A of the Internal Revenue Code, as amended (the “Code”), and as such, may be subject to the imposition of certain excise taxes, surtaxes or other similar taxes, interest and other penalties with respect to amounts or benefits payable under this Agreement in connection with his resignation hereunder in the event such payments or other

5

benefits are found to constitute deferred compensation payments under Section 409A of the Code. Therefore, notwithstanding anything to the contrary in this Agreement, as of the Retirement Date, any Retirement Payment and Benefits or other payments due hereunder, that may constitute deferred compensation payments under Section 409A of the Code may not commence to the Executive until the Payment Date, except to the extent any regulations or guidance issued by the Internal Revenue Service under Section 409A of the Code does not subject such payments or benefits to Section 409A; provided, that any payments in respect of any Retirement Payment and Benefits due to the Executive under Section 3 (whether payable in a lump sum or in installments in accordance with the Company’s regular payroll practices or otherwise) that were so delayed during such six-month period shall be paid in the aggregate as soon as administratively practicable following the Payment Date; provided further, that the delivery to the Executive of any equity of the Company pursuant to Section 3 that was also so delayed during such six-month period will be delivered to him as soon as practicable following the Payment Date.  Notwithstanding the foregoing, in the event of the Executive’s death, the Executive shall be entitled to the amounts required to be paid on the Payment Date under Section 3 as of the first business day of the month immediately following such event and the Company shall make the required payments as promptly as practicable following such date.

(b)

Furthermore, if prior to the Payment Date, Section 409A is modified to allow for any of the payments to be provided hereunder to the Executive to be made prior to the Payment Date without additional cost to the Executive by reason of such earlier payments, then all such payments shall be accelerated and shall be made as promptly as practicable following the release of the modifications to Section 409A, in accordance with the terms of these modifications.

(c)

If any provision of this Agreement contravenes any regulations or Department of Treasury guidance promulgated under Section 409A of the Code, or could cause any amounts or benefits hereunder to be subject to taxes, interest or penalties under Section 409A of the Code, the Company may, in its sole discretion and without the Executive’s consent, modify the Agreement to: (i) comply with, or avoid being subject to, Section 409A of the Code and avoid the imposition of taxes, interest and penalties under Section 409A of the Code, and (ii) maintain, to the maximum extent practicable, the original intent of the applicable provision without contravening the provisions of Section 409A of the Code. This Section 16 is not intended to create an obligation on the part of the Company to modify this Agreement and does not guarantee that the amounts or benefits owed under the Agreement will not be subject to interest and penalties under Section 409A of the Code.

(d)

If the amount of any excise taxes, surtaxes or other similar taxes, interest or penalties imposed against the Executive as a result of his agreeing to remain as Executive Chairman until the Retirement Date are greater than the amount of excise taxes, surtaxes or other similar taxes, interest or penalties that would have been imposed against the Executive if he had retired on May 19, 2009, the Company shall agree to pay any such excess excise taxes, surtaxes or other similar taxes, interest and penalties on behalf of the Executive.

16.

Counterparts.   This Agreement may be executed in one 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.

17.

Headings.   The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement. Unless otherwise expressly provided for in this Agreement, the word “including” or ay variation thereof means “including, without limitation” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately following it.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the day and year first above written.
