--------------------------------------------------------------------------------

“Section 4.6 Freeze of Accruals and Conversion to Accounts. Notwithstanding the
preceding provisions of this Article IV or any other provision of the Plan to
the contrary, effective as of the close of business on November 30, 2016 (the
“Freeze Date”), the following provisions of this Section 4.6 shall apply.
(a) As of the Freeze Date, all future benefit accruals with respect to each
Participant under the Plan shall cease.
(b) The Benefit as of the Freeze Date of each Participant who as of the Freeze
Date is an employee of the Controlled Group and has a Benefit in excess of $0
shall be fully vested on the Freeze Date (subject to Section 4.3(b)(i) of the
Plan).
(c) The Benefit as of the Freeze Date of each Participant who as of the Freeze
Date is an employee of the Controlled Group and has a Benefit in excess of $0
shall be converted to a single sum, effective as of December 1, 2016, in the
amount set forth opposite each such Participant’s name on Exhibit B hereto. The
Benefit as of the Freeze Date of any Participant that is equal to $0 shall
remain $0 on and after the Freeze Date. The single sum amounts set forth on
Exhibit B shall be credited to a notional Account established and maintained for
each such Participant commencing on December 1, 2016. The single sum amounts
shown on Exhibit B were determined in accordance with assumptions designated by
the Chairman, President and Chief Executive Officer, and the Executive Vice
President, Chief Human Resources Officer (the “Authorized Officers”) and
approved by the Board, including projecting to December 31, 2016 the
Participant’s Compensation, Qualified Plan Benefit and the Social Security
Benefit to calculate the present value of the projected accrued benefit as of
December 31, 2016. Further, the Authorized Officers determined that the single

Actuarial Equivalent of the Participant’s Benefit as of the Freeze Date.
    (d) The notional Account established for each Participant pursuant to
Section 4.6(c) shall be (i) deemed to be invested in accordance with the deemed
investments and procedures established by the Committee that are similar to the
deemed investments and procedures established by the Committee pursuant to the
Company’s 2005 Deferred Compensation Plan for Executives, and (ii) credited with
earnings, gains and losses in accordance with such deemed investments. Neither
the Participant nor his beneficiary(s) shall have any interest or right in any
such Account at any time and all amounts credited to such Accounts shall remain
assets of the Employer subject to the claims of such Employer’s general
creditors.
(e) The notional Accounts established for each Participant shall be distributed
in the same form and at the same time that such Participant’s Benefit would have
been distributed without regard to this Section 4.6.
(f) The preceding provisions of this Section 4.6 shall have no effect on any
Benefit of a Participant or beneficiary that was distributed or commenced to be
distributed prior to December 1, 2016.”
