8.14

Deduction Limitation on Benefit Payments.  If the Bank reasonably anticipates that the Bank’s deduction with respect to any distribution under this Agreement would be limited or eliminated by application of Code Section 162(m), then to the extent deemed necessary by the Bank to ensure that the entire amount of any distribution from this Agreement is deductible, the Bank may delay payment of any amount that would otherwise be distributed under this Agreement.  The delayed amounts shall be distributed to the Executive (or the Beneficiary in the event of the Executive’s death) at the earliest date the Bank reasonably anticipates that the deduction of the payment of the amount will not be limited or eliminated by application of Code Section 162(m) and subject to the requirements of Treas. Reg. § 1.409A-2(b)(7)(i).

8.15

Code Section 409A.  It is the intention of the Bank and Executive that this Agreement and all amounts payable hereunder meet the requirements of Code Section 409A, to the extent applicable to the Agreement and such payments.  To the extent applicable, this Agreement shall be interpreted in accordance with Code Section 409A and regulations and other interpretive guidance issued thereunder.  If any compensation or benefits payable under this Agreement do not comply with Code Section 409A and related guidance, the Bank and Executive agree to amend this Agreement or take such actions as the Bank deems necessary or appropriate to comply with the requirements of Code Section 409A while preserving, as nearly as possible, the same economic effect as under this Agreement.
