2.    Effective  October 1, 2006,  Section 4.1, Subsection (B) shall be  DELETED
and replaced with the following:

      (B)   RSOP ALLOCATION  MAKEUP.  For a Participant who was a Participant as
            of September 30, 2006, for so long as he or she remains continuously
            eligible as a  Participant,  an amount equal to the sum of 1.5% plus
            any percentage  being  contributed  under Section  4.4(c)(10) of the
            RSOP  multiplied  by the sum of (1) the  total of the  Participant's
            Annual  Incentive  Award and Other Award for such year, plus (2) the
            amount of the Participant's Compensation not included in calculating
            benefits  under the RSOP due to  limitations  under IRS Code Section
            404(l).  For a  Participant  who becomes a  Participant  on or after
            October  1,  2006,  an  amount  equal  to  the  sum of 6%  plus  any
            percentage being  contributed  under Section  4.4(c)(10) of the RSOP
            multiplied by the sum of (1) the total of the  Participant's  Annual
            Incentive  Award and Other Award for such year,  plus (2) the amount
            of  the  Participant's  Compensation  not  included  in  calculating
            benefits  under the RSOP due to  limitations  under IRS Code Section
            404(l).

            If a Participant transfers to an ineligible status,  dies or Retires
            during the year, this  calculation  will be based on the full Annual
            Incentive  Award and Other  Award.  If a  Participant's  annual  Pay
            exceeds that amount allowed under IRS qualified plan's  compensation
            limit, the amount of  Participant's  annual Pay will be prorated for
            the number of months in an eligible status.

3.    Effective  October 1, 2006,  Section 4.1,  Subsection (C) shall be DELETED
and replaced with the following:

            Participant  as of  September  30,  2006,  for so  long as he or she
            remains  continuously eligible as a Participant,  an amount equal to
            100% of the amount deferred by the Participant  under Section 4.2 of
            this Plan plus any amount  deferred  under  Section 5.1 of the RSOP,
            provided,  however, that for any calendar year, such match shall not
            apply to any  amount  deferred  by a  Participant  in  excess of the
            amount  specified  in  Subsection  4.4(e)(3)(A)  of the  RSOP of the
            Participant's  Compensation  plus Annual  Incentive  Award and Other
            Award.  For a  Participant  who  becomes a  Participant  on or after
            October 1, 2006,  an amount equal to 100% of the amount  deferred by
            the  Participant  under  Section  4.2 of this Plan  plus any  amount
            deferred under Section 5.1 of the RSOP, provided,  however, that for
            any calendar year, such match shall not apply to any amount deferred
            by a  Participant  in excess of the amount  specified in  Subsection
            4.4(e)(3)(B)  of the  RSOP of the  Participant's  Compensation  plus
            Annual  Incentive Award and Other Award. All amounts provided herein
            shall be reduced  by any amount  being  contributed  by the  Company
            under Subsection 4.4(e) of the RSOP.

4.    Effective  January 1, 2007,  Section 4.9  shall  be  amended  to  ADD  the
following at the end of the first sentence of the first paragraph:

            Any annuity provided under this  section shall be calculated using a
            7.5% interest rate, or other rate  as  approved  by  the  Committee.
            Notwithstanding the foregoing, annuities under this section shall be
            calculated  using an 8% interest rate in any  circumstance  in which
            one of the following  conditions  applies:  (i) the Participant left
            service prior to January 1, 2007; or (ii) the  Participant  provided
