AMENDMENT NO. 6 TO

LONGVIEW FIBRE COMPANY

HOURLY EMPLOYEES 401(k) SAVINGS PLAN

This Amendment is made to the Longview Fibre Company Hourly Employees 401(k) Savings Plan (the Plan). All terms defined in the Plan shall have the same meanings when used herein. The amendments set forth below are effective as
of January 1, 2006. All provisions of the Plan not amended by this Amendment shall remain in full force and effect.

1.
Section 4.6 is amended by deleting the last sentence of the first paragraph thereof, deleting the last sentence of the second paragraph thereof, and inserting the following new paragraph at the end thereof:

Any excess Pre-Tax Contributions to be distributed to a Participant (or Matching Contributions related to such excess Pre-Tax Contributions to be
forfeited) in accordance with this Section 4.6 shall be adjusted for investment gain or loss. Effective for Plan Years commencing on or after January 1, 2006, such distributions or forfeitures shall include investment gain or loss for the
period between the end of the applicable Plan Year and the date of distribution or forfeiture. To compute investment gain or loss for a particular period, the Administrator will use a uniform and nondiscriminatory method that reasonably reflects the
manner used by the Plan to allocate income to the Participants Accounts during such period. A method will not fail to be a reasonable method for computing the investment gain or loss allocable to excess Pre-Tax Contributions or related
Matching Contributions merely because the income allocable to such excess amounts is determined on a date that is no more than seven days before the date of distribution or forfeiture.
