##### 



1. The following new unnumbered Section is added to the Plan: Minimum Distribution Requirements. (a) General Rules. (1) Effective Date. The provisions of this Section will apply for purposes of
determining required minimum distributions for calendar years beginning with the 2003 calendar
year. (2) Precedence. The requirements of this Section will take precedence over any
inconsistent provisions of the Plan. (3) Requirements of Treasury Regulations Incorporated. All distributions required
under this Section will be determined and made in accordance with the Treasury regulations under
Section 401(a)(9) of the Code. (4) TEFRA Section 242(b)(2) Elections. Notwithstanding the other provisions of this
Section, distributions may be made under a designation made before January 1, 1984, in accordance
with Section 242(b)(2) of the Tax Equity and Fiscal Responsibility Act (TEFRA) and the provisions
of the Plan that relate to Section 242(b)(2) of TEFRA. (b) Time and Manner of Distribution. (1) Required Beginning Date. The Participants entire interest will be distributed, or
begin to be distributed, to the Participant no later than the Participants required beginning
date. (2) Death of the Participant Before Distributions Begin. If the Participant dies
before distributions begin, the Participants entire interest 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 otherwise provided in this Section, 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 surviving spouse is not the Participants sole designated
beneficiary, then except as otherwise provided in this Section, distributions to the designated
beneficiary will begin by December 31 of the calendar year immediately following the calendar year
in which the Participant died. (C) If there is no designated beneficiary as of September 30 of the year following the year of
the Participants death, the Participants entire interest will be
distributed by December 31 of the calendar year containing the fifth (5th) anniversary of the
Participants death. -2-

##### 



(D) If the Participants surviving spouse is the Participants sole designated beneficiary and
the surviving spouse dies after the Participant but before distributions to the surviving spouse
begin, this subparagraph (2), other than subparagraph (2)(A), will apply as if the surviving spouse
were the Participant. For purposes of this subparagraph (2) and paragraph (d), unless subparagraph (2)(D) applies,
distributions are considered to begin on the Participants required beginning date. If subparagraph
(2)(D) applies, distributions are considered to begin on the date distributions are required to
begin to the surviving spouse under subparagraph (2)(A). If distributions under an annuity
purchased from an insurance company irrevocably commence to the Participant before the
Participants required beginning date (or to the Participants surviving spouse before the date
distributions are required to begin to the surviving spouse under subparagraph (2)(A)), the date
distributions are considered to begin is the date distributions actually commence. (3) Forms of Distribution. Unless the Participants interest is distributed in the
form of an annuity purchased from an insurance company or in a single sum on or before the required
beginning date, as of the first distribution calendar year distributions will be made in accordance
with paragraphs (c) and (d) of this Section. If the Participants interest is distributed in the
form of an annuity purchased from an insurance company, distributions thereunder will be made in
accordance with the requirements of Section 401(a)(9) of the Code and the Treasury regulations. (c) Required Minimum Distributions During Participants Lifetime. (1) Amount of Required Minimum Distributions For Each Distribution Calendar Year.
During the Participants lifetime, the minimum amount that will be distributed for each
distribution calendar year is the lesser of: (A) the quotient obtained by dividing the Participants account balance by the distribution
period in the Uniform Lifetime Table set forth in Section 1.401(a)(9)-9 of the Treasury
regulations, using the Participants age as of the Participants birthday in the distribution
calendar year; or (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 of the Participants and spouses birthdays in the distribution calendar year. (2) Lifetime. Required Minimum Distributions Continue Through Year of Participants
Death. Required minimum distributions will be determined under this paragraph (c) beginning
with the first distribution calendar year and up to and including the distribution calendar year
that includes the Participants date of death. -3-

##### 



(d) Required Minimum Distributions After Participants Death. (1) Death On or After Date Distributions Begin. (A) Participant Survived by Designated Beneficiary. If the Participant dies on or
after the date distributions begin and 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) If 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 age of
the beneficiary in the year following the year of the Participants death, reduced by one for each
subsequent year. (B) No Designated Beneficiary. If the Participant dies on or after the date
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. (2) Death Before Date Distributions Begin. (A) Participant Survived by Designated Beneficiary. Except as otherwise provided in
this Section, if the Participant dies before the date distributions begin and 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 subparagraph (d)(I). (B) No Designated Beneficiary. If the Participant dies before the date distributions
begin and 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
interest will be completed by December 31 of the calendar year containing the fifth anniversary of
the Participants death. -4-

(C) Death of Surviving Spouse Before Distributions to Surviving Spouse Are Required to
Begin. 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 subparagraph (b)(2)(A), this
subparagraph (d)(2) will apply as if the surviving spouse were the Participant. (e) Definitions. (1) Designated beneficiary. The individual who is designated as the beneficiary under
the applicable provisions of the Plan and is the designated beneficiary under Section 401 (a)(9) of
the Code and Section 1.401(a)(9)-I, Q&A-4, of the Treasury regulations. (2) Distribution calendar year. A calendar year for which a minimum distribution is
required. For distributions beginning before the Participants death, the first distribution
calendar year is the calendar year immediately preceding the calendar year which contains the
Participants required beginning date. For distributions beginning after the Participants death,
the first distribution calendar year is the calendar year in which distributions are required to
begin under subparagraph (b)(2). The required minimum distribution for the Participants first
distribution calendar year will be made on or before the Participants required beginning date. The
required minimum distribution for other distribution calendar years, including the required minimum
distribution for the distribution calendar year in which the Participants required beginning date
occurs, will be made on or before December 31 of that distribution calendar year. (3) Life expectancy. Life expectancy as computed by use of the Single Life Table in
Section 1.401(a)(9)-9 of the Treasury regulations. (4) Participants account balance. The account balance as of the last valuation date
in the calendar year immediately preceding the distribution calendar year (valuation calendar year)
increased by the amount of any contributions made and allocated or forfeitures allocated to the
account balance as of dates in the valuation calendar year after the valuation date and decreased
by distributions made in the valuation calendar year after the valuation date. The account balance
for the valuation calendar year includes any amounts rolled over or transferred to the Plan either
in the valuation calendar year or in the distribution calendar year if distributed or transferred
in the valuation calendar year. (5) Required beginning date. The date specified in the applicable provisions of the
Plan relating to required beginning date. -5-
