preceding thirty-six (36) months of employment with the Corporation or Affiliate; provided, however, that a Separation from Service will be deemed to have occurred if it is reasonably anticipated that an Eligible Employee’s service with
the Corporation and its Affiliates will terminate after a certain date or the level of bona fide services that the Eligible Employee will perform after such date (whether as an employee or another capacity) will permanently reduce to a rate that is
less than twenty percent (20%) of the bona fide level of services rendered, on average, during the immediately preceding thirty-six (36) months (or if 

  

 6 

 
employed by the Corporation and its Affiliates less than thirty-six (36) months, such lesser period). However, the employment relationship is treated as
continuing intact while the individual is on military leave, sick leave, or other bona fide leave of absence if the period of such leave does not exceed six months, or if longer, so long as the individual’s right to reemployment with the
service recipient is provided either by statute or by contract. If the period of leave exceeds six months and the individual’s right to reemployment is not provided either by statute or by contract, the employment relationship is deemed to
terminate on the first date immediately following such six-month period. 
 (z) “Supplemental Plans” means the Potlatch
Corporation Salaried Employees’ Supplemental Benefit Plan and Potlatch Corporation Salaried Supplemental Benefit Plan II and any successor plan. 
 (aa) “Year of Vesting Service” means a year of vesting service as determined under the Retirement Plan. 
  

	SECTION	3. ELIGIBILITY AND DETERMINATION OF VESTING SERVICE. 

 All Principal Officers and appointed vice presidents of the Participating Companies and such other employees of the Participating Companies who are designated by the Committee to participate in the Program shall be eligible to participate
in the Program. As a condition to participation in the Program, each Eligible Employee shall agree in writing to become bound by its terms, including, without limitation, the provisions of Section 11. 
  

	SECTION	4. SEVERANCE BENEFITS. 

 (a) Basic Severance
Benefits. Upon the occurrence of any of the events specified in Section 5(a), an Eligible Employee shall receive (in lieu of any other severance benefit payable under any other plan or program now or hereafter maintained by a Participating
Company) Basic Severance Benefits under the Program as follows: 
 (i) A cash benefit equal to three (3) weeks of the
Eligible Employee’s Base Compensation for each full Year of Vesting Service completed by such Eligible Employee; 
 (ii)
The Eligible Employee’s unused and accrued vacation pay, if any, determined as of the date when the Eligible Employee Separates from Service under the terms of the Participating Company’s officer vacation policy as in effect when the
applicable event specified in Section 5(a) occurs (which, in the case of Separation from Service pursuant to Section 5(a)(iv), shall be the date of the material change rather than the date the Eligible Employee Separates from Service);

 (iii) Eligibility for an “Award” under the Incentive Plan for the “Award Year” in which he or she
Separates from Service, determined under all the terms and conditions of the Incentive Plan; and 
 (iv) Continued coverage as
an employee during a period of weeks equal to three (3) times the number of full Years of Vesting Service completed by the Eligible Employee, under the following employee benefit plans of the Corporation: 
  

 7 

 (A) Medical coverage in the amount, if any, that the Eligible Employee had in effect on
the day preceding the date of his or her Separation from Service; 
 (B) Dental coverage in the amount, if any, that the
Eligible Employee had in effect on the day preceding the date of his or her Separation from Service; and 
 (C) Basic life
insurance coverage in the amount, if any, that the Eligible Employee had in effect on the day preceding the date of his or her Separation from Service. 
 Notwithstanding any of the foregoing provisions of this Section 4(a)(iv): 
 (1) Any
such continued coverage shall terminate when the Eligible Employee becomes eligible for coverage by the life insurance, medical or dental plan of another employer. 
 (2) In the event that after an Eligible Employee’s Separation from Service with a Participating Company he or she is otherwise
entitled to continued coverage under the Corporation’s basic life insurance, medical and dental plans pursuant to any employee benefit plan or program of the Corporation (other than this Program), the total benefits paid for by the
Participating Companies during the period described above shall not exceed the benefits to which the Eligible Employee is entitled under this Section 4(a)(iv). 
 (3) For purposes of this Section 4(a)(iv), the Corporation’s basic life insurance plan shall not include any other type of life
insurance coverage provided through or by the Corporation to or on behalf of its employees. 
 (4) During the period of such
continued coverage, the Eligible Employee shall not be eligible to participate in the Corporation’s disability income plan or as an employee in the Retirement Plan, the Salaried 401(k) Plan, any qualified or nonqualified stock incentive or
phantom stock plan of the Corporation or any employee benefit plan or program now or hereafter maintained by any Participating Company other than those plans listed in Section 4(a)(iv)(A)-(C). 
 Notwithstanding the foregoing provisions of this subsection (a), the sum of the amounts payable under (i) above shall be not less
than six (6) months of the Eligible Employee’s Base Compensation nor greater than one (1) year of the Eligible Employee’s Base Compensation and the period of continued coverage described in (iv) above shall be not less than
six (6) months nor more than one (1) year from the Eligible Employee’s Separation from Service. The Committee may, in its discretion, increase the benefit payable to any Eligible Employee without regard to the foregoing limitation.

 (b) Change of Control Benefits. Upon the occurrence of any of the events specified in Section 5(b), an Eligible Employee shall
receive (in lieu of any severance benefit payable under Section 4(a) or any other severance benefit payable under any other plan or program now or hereafter maintained by a Participating Company) Change of Control Benefits under the Program as
follows: 
  

 8 

 (i) Within ten (10) business days following the effective date an Eligible Employee
Separates from Service, a lump sum cash benefit equal to the Eligible Employees’ annual Base Compensation plus his or her annual Base Compensation multiplied by his or her standard bonus percentage (as determined pursuant to the Incentive
Plan), determined as of the date of the Change of Control or the effective date the Eligible Employee Separates from Service, whichever produces the larger amount, multiplied by the appropriate factor from the following table: 
  

			
	 Eligible Employee
	  	Pay Multiple Factor
	 Chief Executive Officer
	  	3.00
	 Other Eligible Employees
	  	2.50

 Notwithstanding the foregoing, if the Eligible Employee Separates from Service on
or after the date thirty (30) months prior to the Eligible Employee’s Normal Retirement Date, the applicable factor shall be a fraction, the numerator of which is the number of full months between the date the Eligible Employee Separates
from Service and such Normal Retirement Date and the denominator of which is twelve (12). An Eligible Employee described in the preceding sentence shall be entitled to an additional benefit equal to the difference between the benefit payable to the
Eligible Employee, if any, under the Retirement Plan and the Retirement Plan Supplemental Benefit provisions of the Supplemental Plans, and such benefits that would have been payable, if any, under the Retirement Plan and Supplemental Plans if the
Eligible Employee had remained an Eligible Employee and continued to earn his or her Base Compensation until his or her Normal Retirement Date; provided, however, that the Present Value of such additional benefit shall not exceed the difference
between the lump sum benefit determined under the preceding sentence and the lump sum benefit determined using the otherwise applicable factor from the table above. Such additional benefit shall be paid at the same time and in the same form as any
benefit payable to the Eligible Employee under the Potlatch Corporation Salaried Supplemental Benefit Plan II or, if no benefit is payable to the Eligible Employee under the such plan, the Present Value of such additional benefit shall be paid
in a lump sum at the same time as the Eligible Employee’s Change of Control Benefits are paid; 
 (ii) A lump sum cash
benefit equal to the Eligible Employee’s unused and accrued vacation pay, if any, under the terms of the Participating Company’s officer vacation policy. For this purpose, (A) an Eligible Employee’s Base Compensation and the
terms of the officer vacation policy shall be determined as of the date when the Eligible Employee Separates from Service or as of the date of the Change of Control, whichever produces the larger amount and (B) accrued vacation pay shall be
paid notwithstanding any minimum service requirement of the Participating Company’s officer vacation policy; 
 (iii)
Eligibility for an “Award” for the “Award Year” in which he or she Separates from Service under the Incentive Plan determined under all the terms and conditions of such plan but based on the Eligible Employee’s target or
standard bonus determined pursuant to such plan; provided, however, that such benefit shall not be payable with respect to any Award Year for which the Eligible Employee receives a payment pursuant to any similar change of control provision in the
Incentive Plan; 
  

 9 

 (iv) COBRA premium payments during the number of years equal to the applicable factor
determined under (b)(i) above, subject to all of the conditions and limitations described in Section 4(a)(iv)(1) through (4) above (determined without regard to the last paragraph of Section 4(a)) under the following employee benefit
plans of the Corporation; 
 (A) Provided that the Eligible Employee timely elects continued coverage under COBRA, medical
coverage in the amount, if any, that the Eligible Employee had in effect on the day preceding the date of his or her Separation from Service; 
 (B) Provided that the Eligible Employee timely elects continued coverage under COBRA, dental coverage in the amount, if any, that the Eligible Employee had in effect on the day preceding the date of his or her
Separation from Service; and 
 (C) Basic life insurance coverage in the amount, if any, that the Eligible Employee had in
effect on the day preceding the date of his or her Separation from Service; 
 (v) In the case of an Eligible Employee who has
less than two (2) Years of Vesting Service on the date he or she Separates from Service, a lump sum cash benefit equal to (A) the value of that portion of the Eligible Employee’s accounts in the Salaried 401(k) Plan attributable to
“Company Contributions” under such plan made on the Eligible Employee’s behalf in a “Plan Year” which are unvested, plus (B) the unvested portion, if any, of the Eligible Employee’s “401(k) Plan Supplemental
Benefit” account under the Supplemental Plans. The value of those portions of the Eligible Employee’s “Company Stock Account” and the “401(k) Plan Supplemental Benefit” accounts referred to in the preceding sentence
shall be determined as of the date the Eligible Employee Separates from Service with the Participating Companies; and 
 (vi)
A lump sum cash benefit equal to the Present Value of the Eligible Employee’s “Normal Retirement Benefit” and “Retirement Plan Supplemental Benefit” determined under the Retirement Plan and the Supplemental Plans,
respectively, if the Eligible Employee was not entitled to a “Vested Benefit” under the Retirement Plan as of the date the Eligible Employee Separates from Service with the Participating Companies. 
 (c) Payment of Excise Taxes. If any payment or benefit to or for the benefit of the Eligible Employee in connection with a Change of Control is
deemed an “excess parachute payment” as defined in Section 280G of the Code subject to the excise tax imposed by Section 4999 of the Code, then in the event it shall be determined that any payment or distribution by a
Participating Company to or for the benefit of the Eligible Employee (whether paid or payable or distributed or distributable pursuant to the terms of this Program or otherwise, but determined without regard to any additional payments required under
this Section 4(c) (a “Payment”)) would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties are incurred by the Eligible Employee with respect to such excise tax (such excise tax,
together with any such interest and penalties, are hereinafter collectively referred to as the “Excise Tax”), then the Eligible Employee shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such
that after payment by the Eligible Employee of all taxes (including any interest or penalties imposed with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and
Excise Tax 

  

 10 

 
imposed upon the Gross-Up Payment, the Eligible Employee retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments.
Notwithstanding the foregoing provisions of this Section 4(c), if it shall be determined that the Eligible Employee is entitled to a Gross-Up Payment, but that the Payments would not exceed the safe harbor amount of 2.99 times the Eligible
Employee’s “base amount,” as defined in Code section 280G(b)(3), by $100,000 or more for the Chief Executive Officer and by $50,000 for other Eligible Employees, then no Gross-Up Payment shall be made to the Eligible Employee and the
Payments, in the aggregate, shall be reduced to an amount such that the receipt of Payments would not give rise to any Excise Tax. In that event, the reduced amount payable (the “Reduced Amount”) shall be determined by reducing or
modifying payments in a manner and order of priority that provides the Eligible Employee with the largest net after-tax value; provided that payments of equal after-tax present value shall be reduced or modified in the reverse order of payment. For
purposes of this Section 4(c), the Eligible Employee shall be deemed to pay federal, state and local taxes at the highest marginal rate of taxation for the applicable calendar year. The amount of the payment to the Eligible Employee shall be
estimated by a third-party service provider selected by the Corporation as of the date of the event specified in Section 5(a) or, if earlier, as of the date of the Change of Control as determined pursuant to Section 5(b). Within thirty
(30) business days following the effective date of an Eligible Employee’s Separation from Service, the estimated amount due the Eligible Employee pursuant to this Section 4(c) shall he paid to the Eligible Employee. In the event that
the amount of the estimated payment is less than the amount actually due to the Eligible Employee under this Section 4(c), the amount of any such shortfall shall be paid to the Eligible Employee within ten (10) business days after the
existence of the shortfall is discovered. 
 (d) No Duty to Mitigate; Offset. The Eligible Employee shall not be required to mitigate
the amount of any payments provided under Section 4(b) and 4(c), nor shall any payment or benefit provided for in Section 4(b) and 4(c) be offset by any compensation earned by the Eligible Employee as the result of employment by another
employer or by retirement benefits. Notwithstanding the foregoing, the Committee in its discretion may reduce any payments provided under Section 4(a), 4(b) and 4(c) (to an amount not less than zero) by any payment(s) that an Eligible Employee
has or will receive pursuant to an arrangement or agreement with a Participating Company that provides for severance payment(s), including related tax payment(s), to which such Eligible Employee may be entitled in the event of termination of
employment. 
  

	SECTION	5. CONDITIONS FOR PAYMENT OF SEVERANCE BENEFITS. 

 (a) Payment Of Basic Severance Benefits. Subject to the provisions of Section 5(c), an Eligible Employee will be eligible for the benefits specified in Section 4(a) upon the occurrence of any of the following events (except
that an Eligible Employee who has satisfied the conditions of Section 5(b) will be eligible for the benefits specified in Section 4(b) rather than the benefits specified in Section 4(a)): 
 (i) The Eligible Employee’s involuntary termination of employment that constitutes a Separation from Service by a Participating
Company or by the Eligible Employee’s Separation from Service at the request of the Company for any reason other than Misconduct, subject to the limitations of Section 5(c)(ii); provided, however, that if the Separation from 

  

 11 

 
Service is due to death or because the Eligible Employee is disabled (as defined in section 409A(a)(2)(C) of the Code), the Eligible Employee shall not be
eligible for any severance benefits under the Program; or 
 (ii) Termination of the Eligible Employee’s employer’s
status as a Participating Company due to the sale to a third party or a spin-off of a designated subsidiary, subject to the limitations of Section 5(c)(ii) and provided that such transaction is a change in the ownership or effective control of
the Corporation or a change in the ownership of a substantial portion of the assets of the Corporation as defined in the regulations promulgated under Section 409A of the Code; or 
 (iii) The Participating Company requires the Eligible Employee to relocate his or her principal place of work and the new principal place
of work is fifty (50) or more miles further from the Eligible Employee’s primary residence than was his or her former principal place of work, and the Eligible Employee elects to Separate from Service rather than to relocate; or

 (iv) The Eligible Employee Separates from Service with a Participating Company within twenty-four (24) months
following: 
 (A) A material Reduction in Authority or Responsibility of the Eligible Employee. Whether a Reduction in
Authority or Responsibility of the Eligible Employee is material shall be determined in accordance with the criteria set forth in Section 2(v) in the definition of Reduction in Authority or Responsibility; provided, however, that (I) a
change in the Eligible Employee’s reporting relationship to another executive who is within the same reporting level, (II) a reduction in the Eligible Employee’s business unit budget or a reduction in the Eligible Employee’s
business unit headcount or number of direct reports, or (III) a Reduction in Authority or Responsibility resulting from the transactions contemplated by the Separation and Distribution Agreement to be entered into by and between the Corporation
and Clearwater Paper Corporation in connection with the spin-off of Clearwater Paper Corporation, by themselves, shall not constitute a material Reduction in Authority or Responsibility, or 
 (B) Any reduction in the Eligible Employee’s Base Compensation, standard bonus opportunity or long-term incentive opportunity or a
fifteen percent (15%) or greater reduction in the Eligible Employee’s aggregate benefits or perquisites as compared to those of all other employees similarly situated, unless in each case the reduction is applicable to all salaried
employees or all other employees similarly situated; provided, however, that this Section 5(a)(iv) shall apply to the Separation from Service of an Eligible Employee only if the Eligible Employee or the Participating Company has notified the
other party in writing within three (3) months following the occurrence of any such change that the party giving notice considers such change to be a material change encompassed by this Section 5(a)(iv). If the party receiving such notice
does not agree that the change in question is a material change encompassed by this Section 5(a)(iv), it shall give written notice thereof to the party first giving notice hereunder within thirty (30) days after receiving notice and the
matter shall be immediately referred to the Appeals Committee; provided, however, that, within thirty (30) days after receiving written notice that the other party does not agree that the change in question is covered by this
Section 5(a)(iv), the Eligible Employee may request that the matter be submitted 

  

 12 

 
directly to arbitration as provided in Section 11. If necessary, the twenty-four (24) month period specified above shall be extended to a date not
later than thirty (30) days following (I) the announcement of the decision of the Appeals Committee or, if the matter is referred to arbitration within thirty (30) days following the announcement of the Appeals Committee’s
decision, the announcement of the award of the arbitrator, or (II) if the matter is referred directly to arbitration, the announcement of the award of the arbitrator. The Participating Company or the Eligible Employee may each give the notice
described in this Section 5(a)(iv) only once while this Program is in effect. If one party has given notice and the twenty-four (24) month period specified above has commenced running, the other party may not give notice hereunder with
respect to a change occurring during such twenty-four (24) month period. If an Eligible Employee gives notice pursuant to this Section 5(a)(iv) and the Corporation thereafter in good faith makes an adjustment in the Eligible
Employee’s compensation, benefits, assigned job or duties, responsibilities, privileges or perquisites, the Eligible Employee and the Corporation may mutually agree in writing that the notice shall be null and void. 
 Notwithstanding the foregoing, no benefits shall be available under the Program (i) if the Eligible Employee Separates from Service
with a Participating Company because he or she is eligible for or receiving long-term or permanent disability benefits under the Corporation’s disability income plan as in effect on the date of onset of disability or (ii) if the Eligible
Employee satisfies all of the following conditions: 
 (1) He or she Separates from Service on or after his or her Normal
Retirement Date; 
 (2) For the two-year period immediately before retirement, he or she qualified as an Eligible Employee;
and 
 (3) He or she is entitled to benefits under the Retirement Plan, Salaried 401(k) Plan and Supplemental Plans which,
when converted to a straight life annuity (and excluding any portion of the benefit under the Salaried 401(k) Plan which represents contributions by the Eligible Employee), equals, in the aggregate, at least $44,000. 
 (b) Payment Of Change Of Control Benefits. An Eligible Employee will be eligible for the benefits specified in Section 4(b) if, within two
(2) years following a Change of Control, the Eligible Employee Separates from Service under the conditions described in Section 5 (a)(i), (ii) or (iii) or a material change described in Section 5(a)(iv) occurs and the
Eligible Employee thereafter Separates from Service under the conditions described in Section 5(a)(iv); provided, that the Eligible Employee was employed by a Participating Company on the date preceding the Change of Control. 
 (c) Limitations On Eligibility For Benefits. 
 (i) If an Eligible Employee is assigned from one to another Participating Corporation, he or she shall not be considered to have Separated from Service under the provisions of the Program. 
 (ii) The provisions of Section 5(a)(i) and 5(a)(ii) to the contrary notwithstanding, no benefit will be payable hereunder due to an
Eligible Employee’s Separation 

  

 13 

 
from Service because of the sale to a third party or spin-off of a division (or other operating assets) of a Participating Company or to termination of the
Eligible Employee’s employer’s status as a Participating Company upon the sale to a third party or spin-off of a designated subsidiary where such sale or spin-off is a change in the ownership or effective control of the Corporation or a
change in the ownership of a substantial portion of the assets of the Corporation as defined in the regulations promulgated under Section 409A of the Code, if (A) (I) the Eligible Employee is employed by the purchaser of such division,
assets, or subsidiary or such other spun-off entity or (II) such purchaser or spun-off entity is contractually obligated to offer the Eligible Employee the same or a better job and (B) such purchaser or spun-off entity is contractually
obligated to maintain a plan which in all material respects is equivalent to the Program, providing for continuing coverage of the Eligible Employee for two (2) years following the sale or spin-off of such division, assets or subsidiary.

  

	SECTION	6. TIME AND FORM OF BENEFIT. 

 (a) Time of
Benefit. Except as provided in Sections 4(b) and 6(b), distributions made to Eligible Employees will commence on the first payroll pay date following the Eligible Employee’s Separation from Service. 
 (b) Notwithstanding any other provision of the Program, a distribution made to Eligible Employee who is identified as a Key Employee at the time of his
or her Separation from Service will be delayed for a minimum of six months if the Eligible Employee’s distribution is triggered by his or her Separation from Service. Any payment that otherwise would have been made except for the application of
this Section 6(a) during such six-month period will be made in one lump sum payment not later than the last day of the second month following the month that is six months from the date the Eligible Employee Separates from Service. The
determination of which Eligible Employees are Key Employees will be made by the Corporation in its sole discretion in accordance with this Section 6(a) and Sections 416(i) and 409A of the Code and the regulations promulgated thereunder.

 (c) Form of Benefit. The benefits described in Section 4(a)(i) shall be paid in monthly installments over a period not to
exceed twelve (12) months from the date the Eligible Employee Separates from Service pursuant to Section 4, as determined by the Corporation. The benefit described in Section 4(a)(ii) shall be paid in a lump sum. The benefits
described in Sections 4(b)(i), (ii), (v) and (vi) shall be paid in a lump sum. 
  

	SECTION	7. EFFECT OF DEATH OF EMPLOYEE. 

 Should an Eligible
Employee die after Separation from Service but while participating in the Program and prior to the payment of the entire benefit due hereunder, the balance of the benefit payable under the Program shall be paid in a lump sum to the estate of the
Eligible Employee. Continued medical and dental coverage as provided in Section 4(a)(iv) and Section 4(b)(iv), as applicable, shall be available to the Eligible Employee’s surviving spouse only if and to the extent that such coverage
would have been available to such surviving spouse if the Eligible Employee had died as an active salaried employee of a Participating Company. Such coverage shall be determined under the terms of the applicable plan as in effect on the earlier of

  

 14 

 
(i) the date the Eligible Employee Separated from Service or (ii) the date of the Change of Control or the material change described in
Section 5(a)(iv), if applicable. 
  

	SECTION	8. AMENDMENT AND TERMINATION. 

 The Committee
reserves the right to amend or terminate the Program at any time and to increase or decrease the amount of any benefit provided under the Program; provided, however, that as to any individual who has qualified as an Eligible Employee and has become
entitled to any Change of Control Benefit under Section 4(b), the Program cannot be terminated or amended to reduce any benefit provided under Section 4(b) or make any condition pertaining to qualification for the Change of Control Benefit
under Section 4(b) materially more restrictive. Once an individual has qualified as an Eligible Employee, the Program may not be amended to cause such individual to cease to qualify as an Eligible Employee for purposes of determining that
individual’s eligibility for the Change of Control Benefit under Section 4(b). Notwithstanding any other provision of the Program, following a Change of Control this Section 8 may not be amended for a period of three (3) years.

 Notwithstanding the foregoing, the Vice President, Human Resources of the Corporation shall have the power and authority to amend the Plan
with respect to any amendment that (i) does not materially increase the cost of the Plan to the Company or (ii) is required to comply with new or changed legal requirements applicable to the Plan, including, but not limited to, section
409A of the Code. 
  

	SECTION	9. CLAIMS PROCEDURE. 

 (a) Claims. All
applications for benefits and all inquiries concerning claims under the program shall be submitted to the Corporation addressed as follows: “Potlatch Corporation, Plan Administrator under the Potlatch Corporation Severance Program for Executive
Employees, 601 W. First Avenue, Suite 1600, Spokane, Washington 99201.” 
 (b) Denial Of Claims. In the event that any
application for benefits under the Program is denied in whole or in part, the Corporation shall notify the applicant in writing of such denial and shall advise the applicant of the right to a review thereof. Such written notice shall set forth, in a
manner calculated to be understood by the applicant, specific reasons for such denial, specific references to the provisions of the Program on which such denial is based, a description of any information or material necessary for the applicant to
perfect his or her application, an explanation of why such material is necessary and an explanation of the Program’s review procedure and the time limits applicable to such procedures, including a statement of the applicant’s right to
bring a civil action under section 502(a) of ERISA following a denial on review of the claim, as described in Section 10. Such written notice shall be given to the applicant within ninety (90) days after the Corporation receives the
application, unless special circumstances require an extension of time up to an additional ninety (90) days for processing the application. If such an extension of time for processing is required, written notice of the extension shall be
furnished to the applicant prior to the termination of the initial ninety (90) day period. This notice of extension shall indicate the special circumstances requiring the extension of time and the date by which the Corporation expects to render
its decision on the application for benefits. 
  

 15 

	SECTION	10. REVIEW PROCEDURE. 

 (a) Appointment Of
Appeals Committee. The Corporation shall appoint a Appeals Committee which shall consist of three (3) or more individuals who may (but need not) be employees of the Corporation; provided, however, that at all times following a Change of
Control the Appeals Committee shall consist of at least three current (as of the effective date of the Change of Control) or former Corporation officers and directors. The Appeals Committee shall be the named fiduciary which shall have authority to
act with respect to appeals from denials of benefits under the Program. 
 (b) Right To Appeal. Any person whose application for
benefits is denied (or is deemed denied) in whole or in part (or such person’s authorized representative) may appeal the denial by submitting to the Appeals Committee a written request for review of the application within sixty (60) days
after receiving written notice from the Corporation of the denial. The Corporation shall give the applicant (or the applicant’s representative) an opportunity to review pertinent documents in preparing such request for review. 
 (c) Form Of Request For Review. The request for review must be in writing and shall be addressed as follows: “Appeals Committee under the
Potlatch Corporation Severance Program for Executive Employees, 601 W. First Avenue, Suite 1600, Spokane, Washington 99201.” The request for review shall set forth all of the grounds upon which it is based, all facts in support thereof, and any
other matters which the applicant deems pertinent. The Appeals Committee may require the applicant to submit such additional facts, documents or other material as the Appeals Committee may deem necessary or appropriate in making its review.

 (d) Time For Appeals Committee Action. The Appeals Committee shall act upon each request for review within sixty (60) days
after receipt thereof unless special circumstances require an extension of time of up to an additional sixty (60) days for processing the request for review. If such an extension of time for review is required, written notice of the extension
shall be furnished to the applicant prior to the end of the initial sixty (60) day period. 
 (e) Appeals Committee Decision.
Within the time prescribed in Section 10(d), the Appeals Committee shall give written notice of its decision to the applicant and to the Corporation. In the event the Appeals Committee confirms the denial of the application for benefits in
whole or in part, such notice shall set forth, in a manner calculated to be understood by the applicant, the specific reasons for such denial, specific references to the provisions of the Program on which the decision was based, a statement that the
applicant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records and other information relevant to his or her claim, and a statement of the applicant’s right to bring a civil action
under section 502(a) of ERISA. In the event that the Appeals Committee determines that the application for benefits should not have been denied in whole or in part, the Corporation shall take appropriate remedial action as soon as reasonably
practicable after receiving notice of the Appeals Committee’s decision. 
 (f) Section 5(a)(iv) Dispute. In the event that a
dispute involving the application or interpretation of Section 5(a)(iv) is referred to the Appeals Committee as provided therein, the 

  

 16 

 
Appeals Committee shall treat such dispute as an appeal from the denial of a claim for benefits under this Program that is subject to all of the terms and
conditions of this Section 10. 
 (g) Rules And .Procedures. The Appeals Committee shall establish such rules and procedures, consistent with the Program and with ERISA, as it may
deem necessary or appropriate in carrying out its responsibilities under this Section 10. The Appeals Committee may require an applicant who wishes to submit additional information in connection with an appeal from the denial of benefits in
whole or in part to do so at the applicant’s own expense. 
 (h) Exhaustion of Remedies. No legal action for benefits
under the Program may be brought until the claimant (i) has submitted a written application for benefits in accordance with the procedures described in Section 9, (ii) has been notified by the Corporation that the application is
denied, (iii) has filed a written request for review of the application in accordance with the appeal procedures described in Section 10, and (iv) has been notified that the Appeals Committee has denied the appeal. Notwithstanding the
foregoing, if the Corporation or the Appeals Committee does not respond to an Eligible Employee’s claim or appeal within the relevant time limits specified in Sections 9 and 10, the Eligible Employee may bring legal action for benefits under
the Program pursuant to section 502(a) of ERISA. 
  

	SECTION	11. RESOLUTION OF DISPUTES INVOLVING SECTION 5. 

 (a) Arbitration Of Section 5 Dispute. Any dispute, controversy or question arising under Section 5 which is not resolved by the decision of the Appeals Committee (or which the Eligible Employee requests be submitted
directly to arbitration as provided herein) shall be referred for decision by an arbitrator selected by the parties. The proceeding shall be governed by the Rules of the American Arbitration Association then in effect or such rules last in effect
(in the event such Association is no longer in existence). If the parties are unable to agree upon such an Arbitrator within thirty (30) days after either party has given the other party written notice of its desire to submit the dispute,
controversy or question for decision as aforesaid, then either party may apply to the American Arbitration Association for the appointment of an arbitrator or, if such Association is not then in existence or does not desire to act in the matter,
either party may apply to the Presiding Judge of the Superior Court of the City and County of Spokane, State of Washington, for the appointment of an arbitrator to hear the parties and settle the dispute, controversy or question, and such Judge is
authorized to make such appointment pursuant to the Program. The arbitration shall take place at the location mutually agreed to by the parties or, if the parties are unable to agree upon the location, at the location designated by the Arbitrator.
The compensation and expenses of the Arbitrator shall be borne by the Corporation, unless the Arbitrator determines that an Eligible Employee acted willfully and maliciously in connection with his or her claim for benefits under the Program, in
which case the Arbitrator shall direct the Eligible Employee to pay all or a portion of the compensation and expenses of the Arbitrator. 
 (b) Arbitration Exclusive Remedy. Arbitration shall be the exclusive remedy for the settlement of disputes involving the application or interpretation of Section 5. The decision of the Arbitrator shall be final, conclusive and
binding on all interested persons and no action at law or inequity involving the application or interpretation of Section 5 shall be instituted other than to enforce the award of the Arbitrator. 
  

 17 

	SECTION	12. BASIS OF PAYMENTS TO AND FROM PROGRAM. 

 All
benefits under the Program shall be paid by the Corporation. The Program shall be unfunded and benefits hereunder shall be paid only from the general assets of the Corporation. Nothing contained in the Program shall be deemed to create a trust of
any kind for the benefit of Eligible Employees, or create any fiduciary relationship between the Corporation and the Eligible Employees with respect to any assets of the Corporation. The Corporation is under no obligation to fund the benefits
provided herein prior to payment, although it may do so if it chooses. Any assets which the Corporation chooses to use for advance funding shall not cause the Program to be a funded plan within the meaning of ERISA. 
 SECTION 13. NO EMPLOYMENT RIGHTS. 
 Nothing in the
Program shall be deemed to give any individual the right to remain in the employ of a Participating Company or a subsidiary or to limit in any way the right of a Participating Company or a subsidiary to terminate an individual’s employment,
which right is hereby reserved. 
  

	SECTION	14. NON-ALIENATION OF BENEFITS. 

 No benefit payable
under the Program shall be subject to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, and any attempt to do so shall be void. 
  

	SECTION	15. SUCCESSORS AND ASSIGNS. 

 The Program shall be
binding on the Corporation, its successors and assigns, and any parent corporation of the Corporation’s successors or assigns. Notwithstanding that the Program may be binding upon a successor or assign by operation of law, the Corporation shall
require any successor or assign to expressly assume and agree to be bound by the Program in the same manner and to the same extent that the Corporation would be if no succession or assignment had taken place. 
  

	SECTION	16. NOTICES. 

 All notices pertaining to the Program
shall be in writing and shall be deemed given if delivered by hand or mailed with postage prepaid and addressed, in the case of the Corporation to the address set forth in Section 9(a), attention of its Corporate Secretary, and the case of the
Eligible Employee to his or her last known address as reflected in the records of the Corporation. 
  

 18Potlatch Corporation Salaried Supplemental Benefit Plan II

 Exhibit 10.4 
 POTLATCH CORPORATION 
 SALARIED SUPPLEMENTAL BENEFIT PLAN II 
 Effective December 5, 2008 

 POTLATCH CORPORATION 
 SALARIED SUPPLEMENTAL BENEFIT PLAN II 
 Effective December 5, 2008 
 SECTION 1. INTRODUCTION. 
 (a) The Potlatch
Corporation Salaried Supplemental Benefit Plan II (the “Plan”) was established effective December 5, 2008. The purposes of the Plan are: 
 (i) to supplement benefits provided under the Retirement Plan to the extent such benefits are reduced due to the limits of section 401(a)(17) or 415 of the Code; 
 (ii) to provide retirement benefits that take into account deferred Incentive Plan awards; 
 (iii) to provide retirement benefits to certain executives calculated as if they received a standard bonus award under the Incentive Plan;
and 
 (iv) to supplement benefits provided under the 401(k) Plan to the extent that a participant’s allocations of
Company Contributions or Allocable Forfeitures are reduced due to the limits of section 401(a)(17), 401(k)(3), 401(m) or 415 of the Code or because the participant has deferred an Incentive Plan award. 
 (b) This Plan is a successor plan to the Potlatch Forest Products Salaried Employees’ Supplemental Benefit Plan II (the “PFPC Plan”), with
respect to those individuals identified as “Potlatch Employees” pursuant to the Employee Matters Agreement by and between Potlatch Corporation and Clearwater Paper Corporation (the “EMA”). Pursuant to the EMA, all accrued benefit
liabilities under the PFPC Plan with respect to Potlatch Employees have been transferred to and assumed by this Plan. 
 (c) This Plan also
is a successor plan to the Potlatch Corporation Salaried Employees’ Supplemental Benefit Plan (the “Prior Plan”). Effective December 31, 2004, the Prior Plan was frozen and no new benefits are to accrue under it; provided,
however, that any benefits accrued and vested under the Prior Plan before January 1, 2005 continue to be governed by the terms and conditions of the Prior Plan as in effect on December 31, 2004 or on the date of any later amendment,
provided that such amendment is not a material modification of the Prior Plan under section 409A of the Code and regulations promulgated there under (rules relating to nonqualified deferred compensation plans). 
 (d) Pursuant to the EMA, all accrued benefit liabilities under the Prior Plan with respect to “Clearwater Employees” (as defined in the EMA)
have been transferred to and assumed by the Clearwater Paper Corporation Salaried Supplemental Benefit Plan. 
 (e) Any benefits that accrued
under the Prior Plan with respect to Potlatch Employees before January 1, 2005 but that were unvested after December 31, 2004 and any benefits that accrued under the Prior Plan after December 31, 2004 are deemed to 

  

 2 

 
have accrued under this Plan and all such accruals are governed by the terms and conditions of this Plan as it may be amended from time to time. 

(f) This Plan is intended to be a deferred compensation plan, for the benefit of a select group of management or highly compensated employees of
Potlatch Corporation and its affiliates (the “Corporation”). The Corporation intends that the existence of a trust, if any, will not alter the characterization of the Plan as “unfunded” for purposes of ERISA, and will not be
construed to provide income to the Participants under the Plan prior to actual payment of the vested accrued benefits hereunder. The Plan is intended to comply with the requirements of section 409A of the Code. 
 (g) Capitalized terms used in the Plan (other than those defined in Section 2 hereof) shall have the same meanings given to such terms in the
Retirement Plan or the 401(k) Plan, as the context may require. 
 SECTION 2. DEFINITIONS. 
 (a) “Actuarial Equivalent” shall mean “actuarial equivalent” as defined in the Retirement Plan. 
 (b) “Affiliate” means any other entity which would be treated as a single employer with Potlatch under Section 414(b) or
(c) of the Code, provided that, for purposes of determining whether a Separation from Service has occurred, in applying such Sections and in accordance with the rules of Treasury Regulations Section 1.409A-1(h)(3), the language “at
least 50 percent” shall be used instead of “at least 80 percent.”

combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors of the corporation or other entity resulting from such Business Combination (including, without limitation, a corporation or
other entity which as a result of such transaction owns the Corporation either directly or through one or more subsidiaries), 
  

 3 

 (B) no individual, entity or group (within the meaning of Section 13(d)(3) or
14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act)) (a “Person”) (excluding any corporation or other entity resulting from such Business Combination or any employee benefit plan (or related trust)
sponsored or maintained by the Corporation or any of its subsidiaries or such other corporation or other entity resulting from such Business Combination) beneficially owns, directly or indirectly, 30% or more of, respectively, the then outstanding
shares of common stock or common equity of the corporation or other entity resulting from such Business Combination or the combined voting power of the then outstanding voting securities of such corporation or other entity except to the extent that

from such Business Combination were members of the Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such Business Combination; or

Distribution whose election, or nomination for election by the Corporation’s stockholders, was approved by a vote of at least a majority of the members of the Board then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board, but excluding, for purposes of this proviso, any such individual whose appointment to the Board occurs as a result of an actual or threatened election contest with respect to the election or removal
of a member or members of the Board, an actual or threatened solicitation of proxies or consents or any other actual or threatened action by, or on behalf of, any Person other than the Incumbent Board; or 
 (iii) Upon the acquisition on or after the date of the Distribution by any Person of beneficial ownership (within the meaning of Rule
13d-3 promulgated under the Exchange Act) of 30% or more of either

 (i) An officer (a person holding the title of Vice President or higher, the Corporate Secretary, the Corporate Treasurer, the Controller,
or other person designated as an officer by the Corporation or an Affiliate in its sole discretion) of the Corporation or an Affiliate having annual compensation greater than the 

  

 5

determined to be Key Employees as of any Identification Date; 
 (ii) A five percent owner of the Corporation; or 

(iii) A one percent owner of the Corporation having annual compensation from the Corporation and its Affiliates of more than $150,000.

 If a Participant is identified as a Key Employee on an Identification Date, then such Participant shall be considered a Key Employee for

 (n) “Plan” shall mean this Potlatch Corporation Salaried Supplemental Benefit Plan II.

means termination of an Employee’s employment as a common-law employee of the Corporation and each Affiliate of the Corporation. A Separation from Service will not be deemed to have occurred if an Employee continues to provide services to the
Corporation or an Affiliate in a capacity other than as an employee and if the former employee is providing a level of bona fide services that is fifty percent (50%) or more of the average level of services rendered, during the immediately
preceding thirty-six (36) months of employment with the Corporation or Affiliate; provided, however, that a Separation from Service will be deemed to have occurred if it is reasonably anticipated that an Employee’s service with the
Corporation and its Affiliates will terminate after a certain date or the level of bona fide services that the Employee will perform after such date (whether as an employee or another capacity) will permanently reduce to a rate that is less than
twenty percent (20%) of the bona fide level of services rendered, on average, during the immediately preceding thirty-six (36) months (or if employed by the Corporation and its Affiliates less than thirty-six (36) months, such lesser
period). However, the employment relationship is treated as continuing intact while the individual is on military leave, sick leave, or other bona fide leave of absence if the period of such leave does not exceed six months, or if longer, so long as
the individual’s right to reemployment with the service recipient is provided either by statute or by contract. If the period of leave exceeds six months and the individual’s right to reemployment is not provided either by statute or by
contract, the employment relationship is deemed to terminate on the first date immediately following such six-month period.

 SECTION 3. ELIGIBILITY AND PARTICIPATION. 
 Participation in the Plan shall be limited to: 
 (a) All participants in the Retirement Plan whose benefits thereunder are reduced due to the limits of section 401(a)(17) of the Code (limiting the amount of compensation that may be taken into account under the Retirement Plan) or section

 (b) All participants in the Retirement Plan who are
credited with deferred Incentive Plan awards; 
 (c) All participants in the Retirement Plan who otherwise participate in the Incentive Plan,
who are officers of the Corporation and who are required by company policy to retire no later than the Normal Retirement Date; and 
 (d) All
participants in the 401(k) Plan whose allocations of the Company Contributions or Allocable Forfeitures are reduced because the participant has deferred an Incentive Plan award or because of the limits of one or more of the following sections of the
Code: 
 (i) section 401(a)(17) (limiting the amount of compensation that may be taken into account under the 401(k) Plan);

 (ii) section 401(k)(3) (limiting participants’ Deferred Contributions to the 401(k) Plan); 
 (iii) section 401(m) (limiting participants’ Non-deferred Contributions and matching Company Contributions under the 401(k) Plan); or

 (iv) section 415 (limiting overall annual allocations under the 401(k) Plan). 
 Any Employee with whom the Corporation has entered into a contract that provides benefits equivalent to any of the benefits described in this Plan shall
not be eligible to participate in or receive benefits under this Plan to the extent of such equivalent benefits. 
 SECTION 4. AMOUNT OF PLAN
BENEFITS. 
 A Participant’s Plan Benefit shall consist of (to the extent applicable to the Participant) (i) the Retirement Plan
Supplemental Benefit and (ii) the 401(k) Plan Supplemental Benefit. All Plan Benefits shall accrue as of the last day of each Plan Year or as of the date, if earlier, on which the Participant Separates from Service. 
 (a) Retirement Plan Supplemental Benefit. A Participant’s Retirement Plan Supplemental Benefit shall be the amount determined under
Subsection (i) below minus the amount determined under Subsection (ii). 
  

 7 

 (i) All Participants. A Participant’s Retirement Plan Supplemental Benefit
shall be the difference between 
 (A) the actual vested benefits payable under the Retirement Plan to the Participant and his
or her joint annuitant (if any) and 
 (B) the vested benefits that would be payable under the Retirement Plan if (i) the
limitations imposed by sections 401(a)(17) and 415 of the Code did not apply, (ii) any deferred Incentive Plan award credited to the Participant had been paid to the Participant in the year it was deferred and (iii) any benefits payable
under Appendix H of the Retirement Plan were not included. 
 In the case of any Participant who is an officer of the Corporation and who is
required by the corporate mandatory retirement policy to retire no later than the mandatory retirement date, the Retirement Plan Supplemental Benefit also shall include the difference, if any, between the amount determined in Subsection (B) and
the vested benefits that would be payable under the Retirement Plan if modified as in Subsection (B) above and also modified so that the Incentive Plan awards credited to the Participant (both deferred and not deferred) which were recognized by
the Retirement Plan in the Participant’s Final Average Earnings had been 100% of the Standard Bonus (as defined in the Incentive Plan), considering for this purpose, only those years during which the Participant was an officer of the
corporation and was required to retire not later than the mandatory retirement date under the corporate mandatory retirement policy; provided, however, that for individuals who retire in an Award Year beginning on or after January 1, 2007, the
Standard Bonus will be used to calculate Final Average Earnings only with respect to periods prior to January 1, 2007. 
 (ii) Prior Plan Offsets. A Participant’s Retirement Plan Supplemental Benefit shall be reduced by the Participant’s retirement plan supplemental benefit accrued under the Prior Plan. 
 (b) 401(k) Plan Supplemental Benefit. A Participant’s 401(k) Plan Supplemental Benefit shall be the vested amount credited to a bookkeeping
account established pursuant to this Section 4(b). As of the last day of each Plan Year commencing after December 31, 2004, each Participant whose allocations for such Plan Year under the 401(k) Plan are reduced as described in
Section 3(d) above and who has made the maximum Participating Deferred and Participating Non-deferred Contributions permitted under the 401(k) Plan for such Plan Year shall have an amount credited to such bookkeeping account. The amount so
credited shall be the difference between the amount of Company Contributions and Allocable Forfeitures actually allocated to the Participant under the 401(k) Plan for such Plan Year and the amount of Company Contributions and Allocable Forfeitures
that would have been allocated to the Participant under the 401(k) Plan for such Plan Year if the Participant had made Participating Contributions equal to six percent of the Participant’s Earnings (determined without 

  

 8 

 
regarding to section 401(a)(17) of the Code and without regard to the deferral of any Incentive Plan award otherwise payable). 
 Through December 31 of the Plan Year preceding the Plan Year in which payment of the Participant’s entire 401(k) Plan Supplemental Benefit is
made, the amount credited to such bookkeeping account shall be credited with earnings and losses based on the following: 
 (i) For periods prior to January 1, 2009, earnings shall be calculated using an interest rate equal to 70% of the higher of the following averages, compounded annually: (i) the prime rate charged by the major commercial banks as
of the first business day of each month (as reported in an official publication of the Federal Reserve System) or (ii) the average monthly long-term rate of A-rated corporate bonds (as published in Moody’s Bond Record). 
 (ii) For periods on and after January 1, 2009 and prior to the date determined under Section 4(b)(iii), earnings shall be
calculated using an interest rate equal to 120% of the long-term applicable federal rate, with quarterly compounding, as published under Section 1274(d) of the Code for the first month of each calendar quarter. 
 (iii) Effective as soon as practicable after January 1, 2009 as determined by the Committee, for Participant groups identified by the
Committee, earnings and losses shall be calculated by reference to the rate of return on one or more of the investment alternatives that are available under the 401(k) Plan and which are designated by the Committee as available under this Plan. Each
Participant may select (in ten percent (10%) increments) which investment alternative(s) will be used for this purpose with respect to his or her bookkeeping account, and the alternative(s) selected need not be the same as the Participant has
selected under the 401(k) Plan, but any such selection will apply only prospectively. The Committee shall determine how frequently such selections may be changed. 
 The Participant shall become vested in the Participant’s 401(k) Plan Supplemental Benefit upon the earliest of completion of two Years of Vesting Service, attainment of age 65 while an Employee, death while an
Employee or Total and Permanent Disability. 
 SECTION 5. DISTRIBUTIONS OF PLAN BENEFITS. 
 Distributions of Plan Benefits shall be made after the Participant Separates from Service pursuant to the following procedures. 
 (a) Retirement Plan Supplemental Benefit. The Retirement Plan Supplemental Benefits shall be distributed beginning no later than ninety
(90) days following the Participant’s attainment of age 55 or Separation from Service, whichever is later (the “Beginning Date”). If the Participant’s benefit is less than or equal to $50,000 (calculated as an Actuarial
Equivalent lump sum of the amount payable at Normal Retirement) on the Beginning Date, the Participant’s benefit shall be paid in a lump sum. 

  

 9 

 
If the Participant’s benefit is greater than $50,000 (calculated as an Actuarial Equivalent lump sum of the amount payable at Normal Retirement) on the
Beginning Date, the Participant’s benefit shall be paid in the form of an annuity. The Participant may elect the form of annuity payment from the forms available under the Retirement Plan, excluding the Social Security Adjustment option, not
more than thirty days after the Beginning Date. A Participant’s Retirement Plan Supplemental Benefit which is paid in the form of annuity shall be subject to the same actuarial adjustments for form of payment applicable to Retirement Plan
benefits. If a Participant’s Retirement Plan Supplemental Benefit is payable before the Participant is first eligible to receive benefits under the Retirement Plan, the Retirement Plan Supplemental Benefit will be calculated to be the Actual
Equivalent of the amount payable at Normal Retirement. 
 If the Participant fails to make an annuity election pursuant to this
Section 5(a), the vested Retirement Supplemental Benefit shall be distributed in the form of Joint & Survivor 50% Annuity or Single Life Annuity if the Participant is unmarried. 
 (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 Potlatch Corporation Management
Deferred Compensation Plan), or (ii) to the extent authorized by the Committee, December 31, 2008, each Participant shall elect to receive distribution of the Participant’s vested 401(k) Plan Supplemental Benefit in ten 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. This election 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. 
 If the Participant fails to make an election pursuant to this Section 5(b), the vested 401(k)
Plan Supplemental Benefit shall be distributed in a lump sum 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. 
 If a Participant dies before the Participant’s 401(k) Plan Supplemental
Benefit has been completely distributed, such remaining benefit shall be distributed in a lump sum as soon as practicable thereafter to the person who is or would be the Participant’s Beneficiary under the 401(k) Plan. 
 Notwithstanding the foregoing, a lump sum distribution shall be made in the Committee’s (or its delegate’s) discretion to clear out a small
balance held for the benefit of the Participant (or his or her Beneficiary) provided that the Committee’s (or its 

  

 10 

 
delegate’s) decision is evidenced in writing prior to the date of the distribution, the distribution is not greater than the applicable dollar amount
under Section 402(g)(1)(B) of the Code and the payment results in the termination of all benefits due under the plan and all other “account balance plans” treated as a single nonqualified deferred compensation plan with this Plan
under Treasury Regulation Section 1.409A-1(c)(2). 
 To the extent that no bookkeeping account has previously been established for a
Participant and if the amount to be credited to the Participant’s account is less than $1,000 in a Plan year, then no 401(k) Plan Supplement Benefit bookkeeping account shall be established for the Participant in such Plan Year and the deferred
amount shall be distributed to the Participant in cash not later than the end of the Plan Year following the Plan Year in which such amount was deferred. 
 (c) Delayed Distribution to Key Employees. Notwithstanding any other provision of this Section 5, distributions of the Retirement Plan Supplemental Benefit and the 401(k) Plan Supplemental Benefit accounts
made to a Participant who is identified as a Key Employee at the time of his or her Separation from Service will be delayed for a minimum of six months if the Participant’s distribution is triggered by his or her Separation from Service. Any
payment that otherwise would have been made pursuant to this Section 5 during such six-month period will be made in one lump sum payment, without adjustment for interest, not later than the last day of the second month following the month that
is six months from the date the Participant Separates from Service. The determination of which Participants are Key Employees will be made by the Corporation in its sole discretion in accordance with this Section 5(c) and sections 416(i)
(defining key employees) and 409A of the Code and the regulations promulgated thereunder. 
 (d) No Acceleration of Benefits.
Notwithstanding any other provision of the Plan to the contrary, no distribution shall be made from the Plan that would constitute an impermissible acceleration of payment as defined in section 409A(a)(3) of the Code and regulations promulgated
thereunder. 
 SECTION 6. MISCELLANEOUS. 
 (a) Forfeitures. Plan Benefits shall be forfeited under the following circumstances: 
 (i) If the Participant
is not vested in the Retirement Plan Supplemental Benefit or 401(k) Plan Supplemental Benefit when the Participant Separates from Service; or 
 (ii) If the Participant is indebted to the Corporation or any affiliate at the time the Participant or the Participant’s joint annuitant or other Beneficiary becomes entitled to payment of a Plan Benefit. In such
a case, to the extent that the amount of the Plan Benefit does not exceed such indebtedness, the amount of such Plan Benefit shall be forfeited and the Participant’s indebtedness shall be extinguished to the extent of such forfeiture.

  

 11 

 (b) Funding. The Plan shall be unfunded, and all Plan Benefits shall be paid from the general
assets of the Company or from assets held in a grantor trust that is subject to the claims of the Company’s general or judgment creditors. 
 (c) Tax Withholding. The Corporation shall make appropriate arrangements for satisfaction of any federal or state income tax or other payroll-based withholding tax required to be paid by the Participant upon the accrual or payment of
any Plan Benefits. 
 (d) No Employment Rights. Nothing in the Plan shall be deemed to give any individual a right to remain in the
employ of the Corporation or any affiliate or to limit in any way the right of the Corporation or an affiliate to terminate any individual’s employment with or without case, which right is hereby reserved. 
 (e) No Assignment of Rights. 
 (i) Except as otherwise provided in Section 6(a)(ii) with respect to a Participant’s indebtedness to the Corporation or an affiliate or in Section 6(e)(ii), the interest or rights of any person in the Plan or in any
distribution to be made hereunder shall not be assigned (either at law or in equity), alienated, anticipated or subject to the attachment, bankruptcy, garnishment, levy, execution or other legal or equitable process. Any act in violation of this
Section 6(e)(i) shall be void. 
 (ii) All or any portion of a Participant’s Plan Benefit hereunder shall be subject
to the creation, assignment or recognition of a right under a state domestic relations order that is determined to be a “qualified domestic relations order” (within the meaning of section 414(p) of the Code) under the procedures
established by the Corporation for the determination of the qualified status of domestic relations orders and for making distributions under qualified domestic relations orders. 
 (f) Administration. The Plan shall be administered by the Committee. The Committee (or its delegate) shall make such rules, interpretations and
computations as it may deem appropriate, and any decision of the Committee (or its delegate) with respect to the Plan, including (without limitation) any determination of eligibility to participate in the Plan and any calculation of Plan Benefits,
shall be conclusive and binding on all persons. 
 Within 30 days after a Change of Control, the Committee shall appoint an independent
committee consisting of at least three current (as of the effective date of the Change of Control) or former Company officers and directors of the Corporation, which shall thereafter administer all claims for benefits under the Plan. Upon such
appointment the Committee shall cease to have any responsibility for claims administration under the Plan. 
 (g) Amendment and
Termination. 
  

 12 

 (i) The Corporation expects to continue the Plan indefinitely. Future conditions,
however, cannot be foreseen, and the Committee shall have the authority to amend or to terminate the Plan at any time. Notwithstanding the foregoing, the Vice President, Human Resources of the Corporation shall have the power and authority to amend
the Plan provided that such amendment (i) does not materially increase the cost of the Plan to the Corporation or (ii) is required to comply with new or changed legal requirements applicable to the Plan, including, but not limited to,
section 409A of the Code. 
 (ii) In the event of an amendment of the Plan, a Participant’s Plan Benefits shall not be
less than the Plan Benefits to which the Participant would be entitled if the Participant had Separated from Service immediately prior to such amendment. In addition to the foregoing, the Plan may not be amended (including any amendment to this
Section 6(g)) or terminated during the three-year period following a Change of Control if such amendment or termination would alter the provisions of this Section 6(g) or adversely affect a Participant’s accrued Plan Benefits.

 (iii) Except as provided in Subsection (iv), in the event of termination of the Plan, the Participants’ Plan Benefits
may, in the Committee’s discretion, be distributed within the period beginning twelve months after the date the Plan was terminated and ending twenty-four months after the date the Plan was terminated, or pursuant to Section 5, if earlier.
If the Plan is terminated and the Plan Benefits are distributed, the Corporation, in compliance with section 409A of the Code shall terminate all account and non-account balance non-qualified deferred compensation plans with respect to all
participants and shall not adopt a new account or non-account balance non-qualified deferred compensation plan for at least five years after the date the Plan was terminated. 
 (iv) The Committee may terminate the Plan upon a corporate dissolution of the Corporation that is taxed under section 331 of the Code or
with the approval of a bankruptcy court pursuant to 11 U.S.C. Section 503(b)(1(A), provided that the Plan Benefits are distributed and included in the gross income of the Participants by the latest of (A) the Plan Year in which the Plan
terminates or (B) the first Plan Year in which payment of the Plan Benefits is administratively practicable. 
 (h) Successors and
Assigns. The Plan shall be binding upon the Corporation, its successors and assigns, and any parent corporation of the Corporation’s successors or assigns. Notwithstanding that the Plan may be binding upon a successor or assign by operation
of law, the Corporation shall require any successor or assign to expressly assume and agree to be bound by the Plan in the same manner and to the same extent that the Corporation would be if no succession or assignment had taken place. 

(i) Claims and Review Procedure. 
 (i) Informal Resolution of Questions. Any Participant who has questions or concerns about his or her benefits under the Plan is encouraged to 

  

 13 

 
communicate with the Vice President, Human Resources. If this discussion does not give the Participant satisfactory results, a formal claim for benefits may
be made within one year of the event giving rise to the claim in accordance with the procedures of this Section 6(i). 
 (ii) Formal Benefits Claim – Review by Appeals Committee. A Participant may make a written request for review of any matter concerning his or her benefits under the Plan. The claim must be addressed to the Appeals Committee,

extension of time. If such an extension is required, written notice of the extension shall be furnished to the person making the request within the initial 90-day period, and the notice shall state the circumstances requiring the extension and the
date by which the Appeals Committee expects to reach a decision on the request. In no event shall the extension exceed a period of 90 days from the end of the initial period. 
 (iii) Notice of Denied Request. If the Appeals Committee denies a request in whole or in part, he shall provide the person making
the request with written notice of the denial within the period specified in Subsection (ii) above. The notice shall set forth the specific reason for the denial, reference to the specific Plan provisions upon which the denial is based, a
description of any additional material or information necessary to perfect the request, an explanation of why such information is required, and an explanation of the Plan’s appeal procedures and the time limits applicable to such procedures,
including a statement of the claimant’s right to bring a civil action under section 502(a) of ERISA following an adverse benefit determination to review. 
 (iv) Appeal to Appeals Committee. 
 (A) A person whose request has been denied in whole or in part (or such person’s authorized representative) may file an appeal of the decision in writing with the Appeals Committee within 60 days of receipt of
the notification of denial. The appeal must be addressed to: Appeals Committee, Salaried Employees’ Supplemental Benefit Plan II, Potlatch Corporation, 601 W. First Avenue, Suite 1600, Spokane, Washington 99201. The Appeals Committee, for good
cause shown, may extend the period during which the appeal may be filed for another 60 days. The appellant and his or her authorized representative shall be permitted to submit written comments, documents, records and other information relating to
the claim for benefits. Upon request and free of charge, the applicant should be provided reasonable access to and 

  

 14 

 
copies of, all documents, records or other information relevant to the appellant’s claim. 
 (B) The Appeals Committee’s review shall take into account all comments, documents, records and other information submitted by the
appellant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. The Appeals Committee’s review shall not be restricted to those provisions of the Plan cited in the
original denial of the claim. 
 (C) The Appeals Committee shall issue a written decision within a reasonable period of time
but not later than 60 days after receipt of the appeal, unless special circumstances require an extension of time for processing, in which case the written decision shall be issued as soon as possible, but not later than 120 days after receipt of an
appeal. If such an extension is required, written notice shall be furnished to the appellant with the initial 60-day period. This notice shall state the circumstances requiring the extension and the date by which the Appeals Committee expects to
reach a decision on the appeal. 
 (D) If the decision on the appeal denies the claim in whole or in part written notice shall
be furnished to the appellant. Such notice shall state the reason(s) for the denial, including references to specific Plan provisions upon which the denial was based. The notice shall state that the appellant is entitled to receive, upon request and

 (E) The decision of the Appeals Committee on the appeal shall be final, conclusive and binding upon all persons and shall be given the
maximum possible deference allowed by law. 
 (v) Exhaustion of Remedies. No legal or equitable action for benefits
under the Plan shall be brought unless and until the claimant has submitted a written claim for benefits in accordance with Subsection (ii) above, has been notified that the claim is denied in accordance with Subsection (iii) above, has
filed a written request for a review of the claim in accordance with Subsection (iv) above, and has been notified in writing that the Appeals Committee has affirmed the denial of the claim in accordance with Subsection (iv); provided, however, that
an action for benefits may be brought after the Appeals Committee has failed to act on the claim within the time prescribed in Subsection (ii) and Subsection (iv), respectively.

 ADDENDUM A 
 AMENDMENT AND RESTATEMENT OF THE 
 ADDITIONAL BENEFITS PROVIDED TO MICHAEL J. COVEY 
 Except as provided in this amendment and restatement to Addendum A, all of the terms and conditions of the Potlatch Corporation Salaried Supplemental
Benefits Plan II, or successor plan (the “Plan”), shall apply to any benefit payable under the Plan to Michael J. Covey. Potlatch Corporation (“Potlatch”) provided to Mr. Covey a minimum pension benefit guaranteed in his
Employment Agreement dated February 6, 2006, as amended (the “Agreement”), which term ends on February 6, 2009, if he retires at or after age 55. The Agreement provides that Potlatch is obligated to continue to honor the
retirement benefits set forth in Section 5(b)(iv) of the Agreement described below after the term of the Agreement ends. In addition, the amendment to the Agreement provides that Mr. Covey is fully vested in his Plan benefits, but not the
minimum pension benefit provided in Section 5(b)(iv) of his Agreement, as of his first day of employment, which is consistent with the vesting of benefits provided to other Potlatch executives; provided, however, in the event of a Change of
Control, as defined in the Plan, he will be vested in the minimum pension benefit immediately. This amended and restated Addendum A describes the benefits that will be provided to Mr. Covey under the Plan. 
 Michael J. Covey shall be fully vested in the Plan, except for the “Minimum Benefit” described below, on the first day of
employment with Potlatch. Furthermore, if Mr. Covey Separates from Service, as defined in the Plan, at or after age 55, he will receive a Minimum Benefit under the Plan, determined as follows: 
 (a) The positive amount equal to $26,800 minus the Total Monthly Pension Benefits, as defined below (the “Difference”), shall be
paid to Mr. Covey as provided herein. 
 (i) The “Total Monthly Pension Benefits” shall be the sum of the
monthly vested benefit under the Company’s Plan and qualified pension plan, as described in Section 4(a)(i)(B) of the Plan (the “Company Pension Benefits”), plus the monthly benefit under Mr. Covey’s former
employer’s supplemental pension plan and qualified pension plan that would have been provided to Executive, taking into consideration his termination date with his former employer (the “Former Company Pension Benefits”); provided that
the Company Pension Benefits and the Former Company Pension Benefits shall be calculated as the actuarial equivalent of a single life annuity. 
 (b) The payment of the Difference as a monthly single life annuity shall be converted at the Beginning Date, as defined in the Plan, into the 

  

 16 

 
actuarial equivalent form that Executive has validly elected to receive his Retirement Plan Supplemental Benefit under the Plan, which amount shall be paid
at the same time and in the same form as his Retirement Plan Supplemental Benefit. 
 (c) In the event that the Difference is
zero or less, then no additional benefits shall be paid to Mr. Covey hereunder. 
 Notwithstanding the foregoing, if there is a Change of
Control, as defined in the Plan, then Mr. Covey shall immediately vest in his Minimum Benefit and he shall receive his Minimum Benefit upon his Separation from Service without regard to attainment of age 55. 
  

 17 

 ADDENDUM B 
 ADDITIONAL BENEFITS PROVIDED TO BRENT STINNETT 
 Except as provided in this Addendum B, all of the terms and
conditions of the Potlatch Corporation Salaried Supplemental Benefits Plan II (the “Plan”) shall apply to any benefit payable under the Plan to Brent Stinnett. In accordance with the foregoing, the retirement benefits guaranteed to
Mr. Stinnett in his Offer Letter, dated July 18, 2006 and accepted by Mr. Stinnett on July 21, 2006 will be provided under this Addendum B to the Plan to the extent that such minimum retirement benefit are not provided by any
other section of the Plan or under any other section of the Potlatch Salaried Retirement Plan or the Potlatch Salaried 401(k) Plan. The relevant section of Mr. Stinnett’s Offer Letter is reproduced below (references below to the Potlatch
Forest Products Corporation Salaried Retirement Plan and Salaried Savings Plan shall be deemed to include references to the Potlatch Salaried Retirement Plan and Potlatch Salaried 401(k) Plan): 
 You will be considered 100% vested immediately in any benefit you accrue under the terms of the Potlatch Forest Products Corporation Salaried Retirement
Plan and Potlatch Forest Products Corporation Salaried Savings Plan (“Qualified Plans”) and the Potlatch Corporation Supplemental Retirement Plan (“Non Qualified Plan”). Additionally, you will be treated as eligible for early
retirement, death and disability benefits under the terms of both the Qualified and Non-Qualified Plans without meeting the Years of Service requirements that normally apply within these plans. The effect of this provision is to assure that you
begin accruing non-forfeitable pension and 401(k) benefits immediately upon joining Potlatch, and that you may receive plan benefits earlier than age 65 if you should, die, become disabled or choose to retire early (“Qualifying Events”).

 While considered as 100% vested under the terms of the Qualified Plans, no benefits will be payable under the Qualified Plan unless you
meet the requirements contained within these plans. Rather, the Non Qualified Plan will provide and pay all benefits that accrue under the Qualified Plans, as well as, any benefits that accrue under the Non-Qualified Plan, as the case may be, upon
the occurrence of a Qualifying Event. 
  

 18 

 ADDENDUM C 
 ADDITIONAL BENEFITS PROVIDED TO JANE CRANE 
 Except as provided in this Addendum C, all of the terms and
conditions of the Potlatch Corporation Salaried Supplemental Benefits Plan II (the “Plan”) shall apply to any benefit payable under the Plan to Jane Crane. In accordance with the foregoing, the retirement benefits guaranteed to
Ms. Crane in her Offer Letter, dated January 5, 2007 and accepted by Ms. Crane on January 8, 2007, will be provided under this Addendum C to the Plan to the extent that such minimum retirement benefits are not provided by any
other section of the Plan or under any other section of the Potlatch Salaried Retirement Plan or the Potlatch Salaried 401(k) Plan. The relevant section of Ms. Crane’s Offer Letter is reproduced below(references below to the Potlatch
Forest Products Corporation Salaried Retirement Plan and Salaried Savings Plan shall be deemed to include references to the Potlatch Salaried Retirement Plan and Potlatch Salaried 401(k) Plan): 
 You will be considered 100% vested immediately in any benefit you accrue under the terms of the Potlatch Forest Products Corporation Salaried Retirement

retirement, death and disability benefits under the terms of both the Qualified and Non-Qualified Plans without meeting the Years of Service requirements that normally apply within these plans. The effect of this provision is to assure that you
begin accruing non-forfeitable pension and 401(k) benefits immediately upon joining Potlatch, and that you may receive plan benefits earlier than age 65 if you should, die, become disabled or choose to retire early (“Qualifying Events”).

 While considered as 100 % vested under the terms of the Qualified Plans, no benefits will be payable under the Qualified Plans unless
you meet the requirements contained within these plans. Rather, the Non Qualified Plan will provide and pay all benefits that accrue under the Qualified Plans, as well as, any benefits that accrue under the Non-Qualified Plan, as the case may be,
upon the occurrence of a Qualifying Event.
