(i) The intent of the parties is that payments and benefits under this Agreement comply with, or meet the requirements of an exemption underInternal Revenue Code Section 409A and the regulations and guidance promulgated thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted andconstrued consistent with that intent.

(ii) A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreementproviding for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any suchprovision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” Notwithstanding anything to the contrary in this Agreement, if Executive isdeemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered deferred compensationunder Code Section 409A payable on account of a “separation from service,” such payment or benefit shall not be made or provided until the date which is the earlier of (A) the expiration of the six (6)-month period measured fromthe date of such “separation from service” of Executive, and (B) the date of Executive’s death, to the extent required under Code Section 409A. Upon the expiration of the foregoing delay period, all payments and benefitsdelayed pursuant to this Section 21(b)(ii) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to Executive in a lump sum, and any remainingpayments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

(iv) For purposes of Code Section 409A, Executive’s right to receive anyinstallment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual dateof payment within the specified period shall be within the sole discretion of the Company.
