Notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, the Participant shall not be considered to have terminated employment with the Company for purposes of this Award unless the Participant would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A of the Code. Each amount to be paid or benefit to be provided under this Award shall be construed as a separate identified payment for purposes of Section 409A of the Code, and any payments described in this Award that are due within the “short term deferral period” as defined in Section 409A of the Code shall not be treated as deferred compensation unless applicable law requires otherwise. Without limiting the foregoing and notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to this Award (or any other plan or agreement of the Company) during the six-month period immediately following the Participant’s separation from service (including for any “specified employee”) shall instead be paid on the first business day after the date that is six months following the Participant’s separation from service (or death, if earlier).

The Company makes no representation that any or all of the payments described in this Award will be exempt from or comply with Section 409A of the Code and makes no undertaking to preclude Section 409A of the Code from applying to any such payment. The Participant shall be solely responsible for the payment of any taxes and penalties incurred under Section 409A of the Code.
