WHEREAS, the Company and Employee are parties to that certain employment

and the rules, regulations, and transitional guidance promulgated thereunder and
with respect thereto (collectively, “Section 409A”); and

WHEREAS, the Company and Employee now desire to amend the Agreement pursuant to
the transition relief provided by Notice 2007-86, effective immediately, to
ensure that any amounts of nonqualified deferred compensation (as such term is
defined in Section 409A) payable pursuant to the Agreement are paid to Employee

contained in this Amendment and for other good and valuable consideration, the

Notwithstanding anything herein to the contrary, the payment (or commencement of
a series of payments) hereunder of any nonqualified deferred compensation
(within the meaning of Section 409A of the Code) upon a termination of
employment shall be delayed until such time as Employee has also undergone a
“separation from service” as defined in Treas. Reg. 1.409A-1(h), at which time
such nonqualified deferred compensation (calculated as of the date of Employee’s
termination of employment hereunder) shall be paid (or commence to be paid) to
Employee on the schedule set forth in this Section 7 as if Employee had
undergone such termination of employment

--------------------------------------------------------------------------------

(under the same circumstances) on the date of his ultimate “separation from
service.”

Except as otherwise specifically set forth herein, all terms and provisions of
