      on behalf of each Participant who is an Eligible Employee (and who
      otherwise qualifies for Discretionary Contributions including the
      completion of the six month period of Service). A Discretionary
      Contribution for a Plan Year may be made at any time for all or a
      designated portion of the Plan Year but only with respect to periods

                  distributed, no later than as follows:

                  (I)   If the Participant's surviving spouse is the
                        Participant's sole Designated Beneficiary, then, except
                        as provided herein, 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.

                  (II)  If the Participant's surviving spouse is not the
                        Participant's sole Designated Beneficiary, then, except
                        as provided herein, distributions to the Designated

                        the Participant died.

                  (iii) 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 anniversary of the Participant's
                        death.

                  (IV)  If the Participant's surviving spouse is the
                        Participant's sole

<PAGE>

                        Designated Beneficiary and the surviving spouse dies
                        after the Participant but before distributions to the
                        surviving spouse begin, this Section 6A.3(b), other than
                        Section 6A.3(b)(i), will apply as if the surviving
                        spouse were the Participant.

      For purposes of this Section 6A.3(b) and Section 6A.5., unless Section
6A.3(b)(iv) applies, distributions are considered to begin on the Participant's
Required Beginning Date. If Section 6A.3(b)(iv) applies, distributions are
considered to begin on the date distributions are required to begin to the
surviving spouse under Section 6A.3(b)(i). 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 Section 6A.3(b)(i)), the date distributions are
considered to begin is the date distributions actually commence.

            (C)   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 Sections 6A.04.
                  and 6A.05. of this Article 6A. 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 Code Section 401(a)(9) and the treasury
                  regulations.

      6A.4. REQUIRED MINIMUM DISTRIBUTIONS DURING PARTICIPANT'S LIFETIME.
Subject to any Special Election set forth in this Article, the following rules
shall apply:

            (A)   AMOUNT OF REQUIRED MINIMUM DISTRIBUTIONS FOR EACH DISTRIBUTION

                  amount that will be distributed for each Distribution Calendar
                  Year is the lesser of:

                  (I)   the quotient obtained by dividing the RMD Account
                        Balance by the distribution period in the Uniform
                        Lifetime Table set forth in treasury regulations Section
                        1.401(a)(9)-9, using the Participant's age as of the
                        Participant's birthday in the Distribution Calendar
                        Year; or

                  (II)  if the Participant's sole Designated Beneficiary for the
                        Distribution Calendar Year is the Participant's spouse,
                        the quotient obtained by dividing the RMD Account
                        Balance by the number in the Joint and Last Survivor
                        Table set forth in treasury regulations Section
                        1.401(a)(9)-9, using the Participant's and the spouse's
                        attained ages as of the Participant's and spouse's
                        birthdays in the Distribution Calendar Year.

<PAGE>

            (B)   LIFETIME REQUIRED MINIMUM DISTRIBUTIONS CONTINUE THROUGH YEAR
                  OF PARTICIPANT'S DEATH. Required minimum distributions will be
                  determined under this Section 6A.4 beginning with the first
                  Distribution Calendar Year and up to and including the

                        is the quotient obtained by dividing the RMD 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:

                        (1)   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.

                              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.

                        (3)   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 (DEFINED TERM) in the year following
                              the year of the Participant's death, reduced by
                              one for each subsequent year.

                  (II)  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

                        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 RMD 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.

                        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

                        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

                        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 being to the

                  date of this Article 6A that is earlier than January 1, 2003,
                  required minimum distributions for 2002 under this Article 6A.
                  will be determined as follows:

                  (I)   If the total amount of 2002 required minimum
                        distributions under the Plan made to the Distributee
                        prior to the effective date of this Article 6A. equals
                        or exceeds the required minimum distributions determined
                        under this Article 6A., then no additional distributions
                        will be required to be made for 2002 on or after such
                        date to the Distributee.

                        than the amount determined under this Article 6A., then
                        required minimum distributions for 2002 on and after
                        such date will be determined so that the total amount of
                        required minimum distributions for 2002 made to the
                        Distributee will be the amount determined under this
