Exhibit 10.13(i)

AMENDMENT TO THE
CLEARWATER PAPER CORPORATION
SALARIED SUPPLEMENTAL BENEFIT PLAN
The Clearwater Paper Corporation Salaried Supplemental Benefit Plan, as amended
and restated as of January 1, 2012 (the “Plan”), is hereby further amended by
revising the first paragraph of Section 5(b) of the Plan to read as follows,
effective as of December 1, 2013 (the subsequent paragraphs of Section 5(b)
shall remain unchanged):
“(b) 401(k) Plan Supplemental Benefit. By the later of (i) January 31st of the
calendar year immediately following the first calendar year in which the
Participant first accrues a benefit under this Plan (or if earlier, thirty (30)
days after first becoming eligible to participate in the Clearwater Paper
Corporation Management Deferred Compensation Plan or any successor plan), or
(ii) December 31, 2008, each Participant shall elect to receive distribution of
the Participant’s vested 401(k) Plan Supplemental Benefit in fifteen or fewer
annual installments or in a lump sum beginning in the Plan Year (but no later
than March 15th of such Plan Year) following the Plan Year in which the
Participant Separates from Service by filing the prescribed form with the
Corporation. A Participant shall have only one form of payment election in
effect for the entire 401(k) Plan Supplemental Benefit accrued during all Plan
Years beginning prior to January 1, 2014. Prior to each Plan Year beginning on
or after January 1, 2014, a Participant shall be permitted to make a separate
form of payment election for the 401(k) Plan Supplemental Benefit to be accrued
in such Plan Year, provided that a Participant’s form of payment election in
effect for any Plan Year shall remain in effect for the 401(k) Plan Supplemental
Benefit accrued in each subsequent Plan Year unless and until the Participant
makes a new form of payment election in the manner prescribed by the Committee.
Each form of payment election made pursuant to this Section 5(b) shall be
irrevocable. Distribution will be made in accordance with the Participant’s
election except as provided below. The amount of any annual installment shall be
determined by dividing the amount credited to the Participant’s bookkeeping
account as of the last day of the Plan Year preceding the date of distribution
of such installment by the total number of installments elected by the
participant less the number of installments already paid. For purposes of the
Plan, installment payments shall be treated as a single distribution under
section 409A of the Code. All annual installment payments shall be payable no
later than March 15th of the payment year.”
