6.2    Payment of Account

(a)During Life

(1)    Timing of Payment The vested portion of the Participant’s Account shall be paid or begin to be paid within 60 days following the end of the Plan Year in which the Participant has a Separation from Service.

(2)    Method of Payment A Participant may elect to have the Participant’s Account, as adjusted for gains and losses, paid in one of the following ways or any combination thereof:

(A)    In one lump sum;

(B)    In annual installments over four years using the declining digits method, but only if the Participant previously elected this payment method for pre-March 1, 2015 credits;

The Participant’s election under this Section shall be filed in writing with the Administrative Committee.

(3)New Elections Notwithstanding the provisions of subparagraph (1) or (2) above, each Participant with an Account may make one or both of the elections described in subsection (A) or (B) below, provided that the Participant may not make more than one election under each subsection.

(A)Payment Method for Future Credits A Participant may elect in writing to have all Principal Credits made in Plan Years beginning after the Plan

Year in which the election is made, as adjusted for gains and losses under Section 6.1(c), paid in one of the methods described in subparagraph (2) above, other than four year installments as described in (2)(B). This election must be made in accordance with procedures established by the Administrative Committee and will have no impact on the method of payment of amounts credited to the Participant’s Account prior to the first Plan Year beginning after the new election, as adjusted for gains and losses.

(B)Change of Payment Method for Current Account A Participant may change the elected method of payment of all Principal Credits that are and will be credited to the Participant’s Account before the next Plan Year, as adjusted for gains and losses under Section 6.1(c), by delivering a new written election to the Administrative Committee.

(iv)The new payment method is one of the options set forth in subparagraph (2) above, other than four year installments as described in (2)(B).

For purposes of this Section, a payment is each separately identified amount to which the Participant is entitled under the Plan; provided, that entitlement to a series of installment payments is treated as the entitlement to a single payment.

(b)    Death In the event of the death of a Participant before payment of all benefits due, the vested amount remaining in the Participant’s Account will be paid to the Participant’s Beneficiary in the method and over the time period elected by the Participant in subparagraph (a) above. If payment had not commenced at the time of the Participant’s death, payment shall be made or begin to be made within 60 days of the Participant’s death.

(c)    Key Employees Notwithstanding the preceding provisions of this Section 6.2, no payment shall be made from a Key Employee’s Account for at least six months after such Key Employee’s Separation from Service, unless the Participant dies prior to the end of the six-month period.

In all other respects, the Plan is unchanged.
