	9.		The Agreement is hereby amended by adding the following new Section 24:
			“24. Code Section 409A.

     (a) Notwithstanding anything in this Agreement to the contrary, to the extent that any amount or benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code would otherwise be payable or distributable hereunder by reason of the occurrence of Executive’s separation from service, such amount or benefit will not be payable or distributable to Executive by reason of such separation from service unless (i) the circumstances giving rise to such separation from service meet any description or definition of “separation from service” in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition), or (ii) the payment or distribution of such amount or benefit would be exempt from the application of Section 409A of the Code by reason of the short-term deferral exemption or otherwise. This provision does not prohibit the vesting of any amount upon a separation from service, however defined. If this 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 from service.”

     (b) Notwithstanding anything in this Agreement to the contrary, if any amount or benefit specified herein as “subject to Section 24 hereof,” or any other amount or benefit that would otherwise constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code would otherwise be payable or distributable under this Agreement by reason of the Executive’s separation from service during a period in which he is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment 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):

          (i) if the payment or distribution is payable in a lump sum, Executive’s right to receive payment or distribution of such non-exempt deferred compensation will be delayed until the earlier of Executive’s death or the first day of the seventh month following Executive’s separation from service (the “Delay Period”); and

          (ii) if the payment or distribution is payable over time, the amount of such non-exempt deferred compensation that 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 delayed until the earlier of Executive’s death or the end of the Delay Period, whereupon the accumulated amount will be paid or distributed to Executive and the normal payment or distribution schedule for any remaining payments or distributions will resume; and

          (iii) to the extent that this Section 24(b) applies to the provision of Welfare Benefits, Executive shall be entitled to pay the full cost of premiums to maintain the Welfare Benefits during the Delay Period, and the Company shall pay to Executive an amount equal to the amount of such premiums promptly following the end of the Delay Period.

			For purposes of this Agreement, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder.”
	10.		Except as expressly amended hereby, the terms of the Agreement shall be and remain unchanged and the Agreement as amended hereby shall remain in full force and effect.
			IN WITNESS WHEREOF, the Company and Executive have caused this Amendment to be executed on the day and year first above written.
