amended in its entirety to read as follows:

“(c)         For periods prior to January 1, 2007,
except as provided in the following paragraph, for conversions under Section
4.6(b), for optional forms paid according to Section 4.6(e), early retirement
under Section 4.3, conversions with respect to annuity payments made pursuant
to qualified domestic relations orders and adjustments under Sections 9.4 and
9.4A(b)(2)(B)(i)(B), the UP-1984 Table of Mortality at 71⁄2 percent interest,

interest at 71⁄2 percent shall be used and the UP-1984 Table of Mortality.

Effective January
1, 2007, for conversions under Section 4.6(b), for optional forms paid
according to Section 4.6(e), early retirement under Section 4.3, conversions
with respect to annuity payments made pursuant to qualified domestic relations
orders and adjustments under Sections 9.4 and 9.4A(b)(2)(B)(i)(B), the UP-1994
Mortality Table projected to 2002 using Scale AA (blended 50% male, 50% female;

for Top-Heavy determinations, interest at 71⁄2 percent and the UP-1994 Mortality
Table projected to 2002 using Scale AA (blended 50% male, 50% female; without

replaced with “180 days.”

3.                                       Effective
January 1, 2007, Section 4.6(e)(3) of the Plan is redesignated Section
4.6(e)(4) and a new Section 4.6(e)(3) is hereby added to the Plan to read as
follows:

“(3)         75% Joint and Survivor Annuity.  A married Participant or Former Participant
may elect to have his pension paid in the form of a 75% joint and survivor
annuity, which shall be the Actuarial Equivalent of the normal form for single
Participants described in Section 4.6(a) payable for life to the Participant or
Former Participant and, thereafter, for the life of the Participant’s or Former
Participant’s Surviving Spouse in an amount equal to 75% of the amount that was
payable to the Participant or Former Participant.”

4.                                       Effective

“(B)         If the benefit of a Participant begins
prior to age 62, the defined benefit dollar limitation applicable to the
Participant at such earlier age is an annual benefit payable in the form of a
straight life annuity beginning at the earlier age that is the actuarial
equivalent of the defined benefit dollar limitation applicable to the
Participant at age 62 (adjusted under (a) above, if required). The defined
benefit dollar limitation applicable at an age prior to age 62 is determined as
the lesser of (i) the actuarial equivalent (at such age) of the defined benefit
dollar limitation computed using (A) an interest rate of 7 1/2%; and (B) the
applicable mortality table described in paragraph (c) under the definition of “Actuarial
Equivalent(ce) or Actuarially Equivalent” in Section 2.1; and (ii) the
actuarial equivalent (at such age) of the defined benefit dollar limitation
computed using (A) a 5% interest rate; and (B) the applicable mortality table
as defined in Section 2.1, paragraph (e) of the definition of “Actuarial
Equivalent(ce) or Actuarially Equivalent” under the heading “Mortality Table

and Treas. Reg. Section 1.417(e)-1T(d)(2) (as set forth in paragraph (b) of the
definition of “Actuarial Equivalence”) for Annuity Starting Dates prior to
December 31, 2002. Any decrease in the defined benefit dollar limitation
determined in accordance with this subparagraph (B) shall not reflect a
mortality decrement if benefits are not forfeited upon the death of the
Participant. If any benefits are forfeited upon death, the full mortality
decrement is taken into account.”

IN WITNESS WHEREOF, and as evidence of the adoption of
the amendment set forth herein, the Committee has caused this instrument to be
executed this       day of                 ,
