Pursuant to Internal Revenue Code Section 409A, there are multiple restrictions and limitations regarding modifying the time and/or form of such payments; however an exception to these restrictions permits elections to change from a life annuity to another actuarially equivalent life annuity (prior to payments beginning). In the event no alternate method is selected above, then amounts due under this Agreement shall be paid out as a single life annuity based on the life of the Participant. Subject to the forgoing, and provided that payments have not yet begun, Executive may elect to have the Executive Benefit paid as follows: Election of Actuarial Equivalent of Form of Benefit For Married Participant or Participant with Domestic Partner. Pursuant to the terms of the Agreement, and consistent Code Section 409A, instead of having my benefit paid as a single life annuity, with payments continuing until my death, I elect to have my benefit paid to me as designated below: _________ A joint and survivor annuity with an actuarial equivalent of the benefit owing pursuant to the Agreement, with payment continued to the surviving spouse in the same amount as the amount paid to me. _________ A joint and survivor annuity in equal value to the actuarial equivalent of the benefit owing pursuant to the Agreement, with payment continued to my surviving spouse (registered domestic partner) in one-half of the amount paid to me. Acknowledgment of Limitations on Changes in Time and Form of Payment of Benefits. All Actuarially Equivalent valuations must be in compliance with Code Section 409A and 1.409A-2(b)(2)(ii). In addition, when determining whether two life annuities are Actuarially Equivalent, the same actuarial assumptions and methods must be used in valuing each life annuity. This requirement applies over the entire term of Participant’s participation in the plan, such that the annuities must be actuarially equivalent at all times for the annuity options to be treated as one time and form of payment. However, provided the actuarial methods and assumptions are reasonable, there is no requirement that consistent actuarial assumptions and methods be used over the term of the Participant’s participation in the plan. Accordingly, the plan may change the actuarial assumptions and methods used to determine the life annuity payments, provided that all of the actuarial assumptions and methods are reasonable. In the event, however, that a joint and survivor annuity option is selected, and that Participant’s spouse predeceases Participant, then for all payments made to Participant after the Participant’s spouse’s death, the amounts payable under this Agreement shall increase and be equal to the payment amounts Participant would have received under a single life annuity option. In addition, Participant shall no longer have the ability to make a new joint and survivor annuity election. In the event no alternate method is selected above, then amounts due under this Agreement shall be paid out as a single life annuity. To the extent that any paragraph, term, or provision of the Agreement is not specifically amended herein, or in any other amendment thereto, said paragraph, term, or provision shall remain in full force and effect as set forth in said Agreement. WHEREFORE, the Insured and a duly authorized Bank officer have signed this Amendment as of the written date Signed: Print Name: Dated:
