Payment of any reimbursement amounts and the provision of any benefits by the Company pursuant to this letter (including any reimbursements or benefits to be provided pursuant to a severance arrangement) which the Company determines constitute nonqualified deferred compensation (within the meaning of Code section 409A) shall be subject to the following:

The foregoing amendment is intended to conform the terms of the Letter to the final regulations issued under section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), but it shall not provide a basis for any action against the Company or any related company based on matters covered by section 409A of the Code.
