If a Participant dies before distributions begin, the Participant’s entire Vested Benefit will be distributed, or begin to be distributed, no later than as follows:

(a)           If the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary, then except as provided in Section 6.1, distributions to the surviving spouse will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died, or by December 31 of the calendar year in which the Participant would have attained age 70-1/2, if later.

(b)           if the Participant’s sole Designated Beneficiary for the Distribution Calendar Year is the Participant’s spouse, the quotient obtained by dividing the Participant’s Account Balance by the number in the Joint and Last Survivor Table set forth in section 1.401(a)(9)-9 of the Treasury Regulations, using the Participant’s and spouse’s attained ages as

REQUIRED MINIMUM DISTRIBUTIONS

AFTER PARTICIPANT’S DEATH

4.1          Death On or After Date Distribution Begins

If a Participant dies on or after the date distributions begin, the following rules shall apply to the distribution of the Participant’s Account Balance, if any.

(a)           If there is a Designated Beneficiary, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the longer of the remaining Life Expectancy of the Participant or the remaining Life Expectancy of the Participant’s Designated Beneficiary, determined as follows:

(i)            The Participant’s remaining Life Expectancy is calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.

(ii)           The Participant’s surviving spouse is the Participant’s sole Designated Beneficiary, the remaining Life Expectancy of the surviving spouse is calculated for each Distribution Calendar Year after the year of the Participant’s death using the surviving spouse’s age as of the spouse’s birthday in that year.  For Distribution Calendar Years after the year of the surviving spouse’s death, the remaining Life Expectancy of the surviving spouse is calculated using the age of the surviving spouse as of the spouse’s birthday in the calendar year of the spouse’s death, reduced by one for each subsequent calendar year.

(iii)          If the Participant’s surviving spouse is not the Participant’s sole Designated Beneficiary, the Designated Beneficiary’s remaining Life Expectancy is calculated using the

4

age of the beneficiary in the year following the year of the Participant’s death, reduced by one for each subsequent year.

(b)           If the Participant dies before distributions begin and there is no Designated Beneficiary as of September 30 of the year after the year of the Participant’s death, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the Participant’s remaining Life Expectancy calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.

4.2          Death Before Date Distributions Begin

If the Participant dies before the date distributions begin, the following rules shall apply.

(a)           If there is a Designated Beneficiary, the minimum amount that will be distributed for each Distribution Calendar Year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s Account Balance by the remaining Life Expectancy of the Participant’s Designated Beneficiary, determined as provided in Section 4.1 of this Appendix “A”.

(b)           If there is no Designated Beneficiary as of September 30 of the year following the year of the Participant’s death, distribution of the Participant’s entire Vested Benefit will be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.

(c)           If the Participant dies before the date distributions begin, the Participant’s surviving spouse is the Participant’s sole Designated Beneficiary, and the surviving spouse dies before distributions are required to begin to the surviving spouse under Section 2.2(a) of this Appendix “A”, this Section 4.2 will apply as if the surviving spouse were the Participant.
