1. Section 409A. The Agreement is hereby amended by adding the following Section 25: 

“25. Provisions Relating to Section 409A of the Code. 

(a) General. This Agreement shall beinterpreted and administered in a manner so that any amount or benefit payable hereunder shall be paid or provided in a manner that is either exempt from or compliant with the requirements Section 409A of the Internal Revenue Code of 1986, asamended, and applicable Internal Revenue Service guidance and Treasury Regulations issued thereunder (and any applicable transition relief under Section 409A of the Code) (“Section 409A”). Nevertheless, the tax treatment of theamounts or benefits provided under the Agreement is not warranted or guaranteed. Neither the Company nor its directors, officers, employees or advisers shall be held liable for any taxes, interest, penalties or other monetary amounts owed byExecutive as a result of the application of Section 409A. 

(b) Separation from Service. Notwithstanding anythingin this Agreement to the contrary, as required by Section 409A, the severance payments under subsection 4(d)(i), whether payable by reason of subsections 4(b), (d) or (e), and any other amount or benefit that would constitute non-exempt“deferred compensation” for purposes of Section 409A and that would otherwise be payable or distributable hereunder by reason of Executive’s termination of employment (collectively, the “Termination Benefits”), will notbe payable or distributable to Executive unless the circumstances giving rise to such termination of employment meet any description or definition of “separation from service” in Section 409A (without giving effect to any electiveprovisions that may be available under such definition). This provision does not prohibit the *vesting* of any amount upon Executive’s termination of employment or the determination of the amounts owed to him due to such termination. Ifthis provision prevents the payment or distribution of any amount or benefit, such 

payment or distribution shall be made on the date, if any, on which an event occurs that constitutes a Section 409A-compliant “separation fromservice,” or such later date as may be required by subsection (c) below. 

(c) Six-Month Delay in CertainCircumstances. Notwithstanding anything in this Agreement to the contrary, as required by Section 409A, if the severance payments under subsection 4(d)(i), whether payable by reason of subsections 4(b), (d) or (e), or any otherTermination Benefit, become payable or distributable under this Agreement by reason of Executive’s separation from service during a period in which he is a Specified Employee (as defined below), then, subject to any permissible acceleration ofpayment by the Company under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes), the amount of such severance payment or other Termination Benefitthat would otherwise be payable during the six-month period immediately following Executive’s separation from service will be accumulated and Executive’s right to receive payment or distribution of such accumulated amount will be delayeduntil the earlier of (i) a date no later than thirty (30) days following Executive’s death or (ii) the first day of the seventh month following Executive’s separation from service, whereupon the accumulated amount will bepaid or distributed to Executive on such date and the normal payment or distribution schedule for any remaining payments or distributions will resume. 

For purposes of this Agreement, the term “Specified Employee” has the meaning given such term in Section 409A; *provided, however*, that the Company’s Specified Employees and its applicationof the six-month delay rule of Code Section 409A(a)(2)(B)(i) shall be determined in accordance with rules adopted by the Board or a committee thereof, which shall be applied consistently with respect to all nonqualified deferred compensationarrangements of the Company, including this Agreement. 

(d) Timing of Waiver and Release of Claims. Whenever in thisAgreement the provision of payment or benefit is conditioned on Executive’s execution and non-revocation of a waiver and release of claims, such waiver and release must be executed, and all revocation periods must have expired, within 60 daysafter the date of termination of Executive’s employment, but the Company may elect to commence payment at any time during such 60-day period. 

(e) Timing of Reimbursements and In-kind Benefits. If Executive is entitled to be paid or reimbursed for any taxable expenses under this Agreement, including but not limited to subsection 3(f) andSection 22, and such payments or reimbursements are includible in Executive’s federal gross taxable income, the amount of such expenses reimbursable in any one calendar year shall not affect the amount reimbursable in any other calendaryear, and the reimbursement of an eligible expense must be made no later than December 31 of the year after the year in which the expense was incurred. No right of Executive to reimbursement of such expenses shall be subject to liquidation orexchange for another benefit. Any reimbursement shall be for expenses incurred during Executive’s lifetime (or during a shorter period of time specified in this Agreement).

(f) Treatment of Installment Payments. Each installment payment of severancebenefits shall be considered a separate payment, as described in Treas. Reg. Section 1.409A-2(b)(2), for purposes of Section 409A.”
