A Participant may elect to defer up to 100% of a refund of excess contributions from the 401(k) plan of the Company received by such Participant during the same year, provided such election is in accordance with the terms of the Plan and the Deferral Election Form.

2. Payment Dates for Termination Account. Section 5.08(a)(iv) is hereby deleted in its entirety and replaced with the following:

(iv) Annual installment payments shall be for no less than two (2) and no more than twenty (20) annual installments (as indicated in the Participant’s most recent effective Deferral Election Form). The initial annual installment payment shall be equal to the value of the Participant’s Account on the applicable Valuation Date divided by the number of remaining installments to be paid (including the then-current installment payment). Thereafter, each subsequent annual installment payment shall be made in January of each subsequent year and in an amount equal to the value of the Participant’s Account as of December 31 of the preceding year divided by the total number of annual installment payments remaining to be paid (including the then-current annual installment payment).
