13. You acknowledge and agree that you are not relying on any representations or promises by any representative of the Company concerning the meaning of any aspect of this Agreement.  This Agreement may not be altered or modified other than in a writing signed by you and an authorized representative of the Company.  To the extent not governed by federal law, this Agreement shall be governed by, construed, and interpreted in accordance with the laws of the State of New York, without reference to its choice of law rules.  The Company’s offer to you of this Agreement is not intended to, and shall not be construed as, any admission of liability or of any improper conduct on the part of the Company or any of the Releasees.

16. This Agreement is intended to be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and will be interpreted in a manner intended to provide exemption from Section 409A of the Code.  Notwithstanding anything herein to the contrary, if at the time of your termination of employment with the Company you are a “specified employee” as defined in Section 409A of the Code (and any related regulations or other pronouncements thereunder) and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A of the Code, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or benefits ultimately paid or provided to you) until the date that is six (6) months following your termination of employment with the Company (or the earliest date as is permitted under Section 409A of the Code).  To the extent that any reimbursements or in-kind benefits due to you under this Agreement constitute “deferred compensation” under Section 409A of the Code, any such reimbursements or in-kind benefits shall be paid to you in a manner consistent with Treasury Reg. Section 1.409A-3(i)(1)(iv) or any successor thereto.  Each payment made under this Agreement shall be designated as a “separate payment” within the meaning of Section 409A of the Code.  All payments constituting deferred compensation subject to Section 409A of the Code that are to be made upon a termination of employment under this Agreement may only be made upon a “separation from service” within the meaning of such term under Section 409A of the Code.
