she has not obtained a position with another employer (despite reasonable, diligent and good faith efforts to do so) at a salary comparable to the Eligible Employees Base Compensation, a cash benefit equal to an additional week of Base
Compensation for each full Year of Vesting Service completed by the Eligible Employee; provided, however, that such benefit shall not be payable if the Eligible Employee is not living on the last day of the period described herein;

employment is terminated under the terms of the Participating Companys basic vacation policy as in effect when the applicable event specified in Section 4(a) occurs (which, in the case of termination of employment pursuant to Section 4(a)(iv),
shall be the date of the material change rather than the date the Eligible Employee resigns);



(v) Eligibility for an Award under the Companys Management Performance Award Plan for the Award Year in which his or her employment
terminates, determined under all the terms and conditions of such plan; and



(vi) Continued coverage as an employee during a period of weeks equal to three (3) (four (4), in the case of an Eligible Employee eligible for the benefit described in (ii) above) times the number of full Years of

standard group rates.



Notwithstanding any of the foregoing provisions of this
Section 3(a)(vi):



(I) Any such continued
coverage shall terminate when the Eligible Employee becomes covered by the life insurance, medical, dental or accidental death and dismemberment plan of another employer.



(II) In the event that after an Eligible Employees termination of employment with a Participating
Company he or she is otherwise entitled to continued coverage under the Companys basic life insurance, medical, dental and accidental death and dismemberment plans pursuant to any employee benefit plan or program of the Company (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 3(a)(vi).



(III) For purposes of this Section 3(a)(vi), the
Companys basic life insurance plan shall not include any group universal life insurance or travel accident insurance coverage provided through or by the Company to or on behalf of its employees or any accidental death and dismemberment

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:



(i) Within ten (10) business days following the effective date an Eligible Employee terminates, a lump sum

of the date of the Change of Control or the effective date the



5



---

Eligible Employee terminates, whichever produces the larger amount, multiplied by the appropriate factor from the following table:



|                         |  |                   
|------------------------ |  | ------------------
|Eligible Employee        |  | Pay MultipleFactor
|Chief Executive Officer  |  | 3.0               
|                         | 
|Chief Operating Officer  |  | 3.0               
|                         | 
|Other Eligible Employees |  | 2.5               



Notwithstanding the
foregoing, if the Eligible Employees employment terminates on or after the date thirty (30) months prior to the Eligible Employees normal retirement date, as determined under the Retirement Plan, the applicable factor shall
be a fraction, the numerator of which is the number of full months between the date the Eligible Employees employment terminates 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 Salaried Employees Supplemental Benefit Plan (the Supplemental Plan), and such benefits that would have been payable, if any, under such Plans if the Eligible Employee had remained an Eligible Employee and continued to earn his
or her Base Compensation until such normal retirement date; provided, however, that the present value (calculated using the assumed discount rate applied in projecting the Companys pension benefit obligations for financial
reporting purposes and the UP-84 mortality table) (the Present Value) of such additional benefit shall not exceed the difference between the lump sum benefit



6



---

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 Supplemental Plan or, if no benefit is payable to the Eligible Employee under the Supplemental 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) In the event that a Participating Company terminates the employment of an Eligible Employee and does not give him or her one
months advance notice, one month of the Eligible Employees Base Compensation (determined as of the date of the Change of Control or the date the Eligible Employees employment terminates, whichever produces the larger amount) in
lieu of notice;



(iii) 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 basic vacation policy. For this purpose, (I) an Eligible Employees Base Compensation and the terms of the basic
vacation policy shall be determined as of the date when the Eligible Employees employment is terminated or as of the date of the Change of Control, whichever produces the larger amount and (II) accrued vacation pay shall be paid
notwithstanding any minimum service requirement of the Participating Companys basic vacation policy;



(iv) Eligibility for an Award under the Companys Management Performance Award Plan for the Award Year in which his or her employment
terminates determined under all the terms and conditions of such Plan;



7



---

(v) Continued coverage as an employee 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 3(a)(vi)(I) through (IV) above (determined without regard to the last paragraph of Section 3 (a)) under the following employee benefit plans
of the Company;



(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 termination of employment;



(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
termination of employment;



(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 termination of employment;



(D) Accidental death and dismemberment coverage (not including travel accident coverage) in the amount, if any, that the Eligible Employee
had in effect on the day preceding the date of his or her termination of employment, except that continuation of any employee-paid coverage shall be at the Eligible Employees expense at standard group rates; and



(E) Temporary, long-term and permanent disability income
coverage in the amount, if any, that the Eligible Employee had in effect on the day preceding the date of his or her termination of employment;



(vi) In the case of an Eligible Employee who has less than five (5) Years of Vesting Service on the date his or her employment terminates,
a lump sum cash benefit equal to (A) the value of that portion of the Eligible Employees Company Stock Account



8



---

in the Salaried Employees Savings Plan attributable to Company Contributions under such Plan made on the Eligible Employees behalf in a Plan Year
which ended less than 24 months prior to the date the Eligible Employees employment with the Participating Companies terminates, plus (B) the unvested portion, if any, of the Eligible Employees Savings Plan Supplemental Benefit account
under the Supplemental Plan. The value of those portions of the Eligible Employees Company Stock Account and the Savings Plan Supplemental Benefit account referred to in the preceding sentence shall be determined as of the date the Eligible
Employees employment with the Participating Companies terminates; and



(vii) 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
Plan, respectively, if the Eligible Employee was not entitled to a Vested Benefit under the Retirement Plan as of the date the Eligible Employees employment with the Participating Companies terminates.



(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 Internal Revenue Code of 1986 (the Code) subject to the excise tax imposed by
Section 4999 of the Code, the Company shall pay to the Eligible Employee an additional amount such that the total amount of all such payments and benefits (including payments made pursuant to this Section 3(c)) to the Eligible Employee shall equal
the total amount of all such payments and benefits to which the Eligible Employee would have been entitled (but for this Section 3(c)) net of all applicable federal, state and local



9



---

taxes except the excise tax. For purposes of this Section 3(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 Company as of the date of the event specified in Section 4(a) or, if
earlier, as of the date of the Change of Control as determined pursuant to Section 4(b). Within thirty (30) business days following the effective date an Eligible Employee terminates, the estimated amount due the Eligible Employee pursuant to this
Section 3(c) shall be 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 3(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.



The Eligible Employee shall not be required to mitigate the amount of any payments provided under Section 3(b) and 3(c), nor shall any payment or benefit
provided for in Section 3(b) and 3(c) be offset by any compensation earned by the Eligible Employee as the result of employment by another employer or by retirement benefits.



(d) Definition of Base Compensation. For purposes of the Program, Base Compensation shall
mean the Eligible Employees base rate of pay as in effect at the time the Eligible Employees employment is terminated, or, if greater, the rate in effect at the time the material change described in Section 4(a)(iv) occurs or the time a
Change of Control described in Section 4(b) occurs, if applicable. An Eligible Employees base rate of pay shall be determined without reduction for (i) any Deferred Contributions made by the Eligible Employee pursuant to the Potlatch
Corporation Salaried Employees Savings Plan or (ii) any contributions made by the Eligible Employee pursuant to the Potlatch Corporation Custom Benefits Plan.

(i) Termination of the Eligible Employees employment by a Participating Company or by the Eligible Employee at the request of the

resign rather than to relocate or



(iv) The
Eligible Employee resigns from employment with a Participating Company within twenty-four (24) months following (A) a significant diminution of the Eligible Employees assigned job, as reflected in the Participating Companys official

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 4(a)(iv) shall apply to the resignation 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 4(a)(iv). If the party receiving such notice does not agree that the change in question is a material change encompassed by this Section 4(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 Review Panel as provided in Section 9; 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 4(a)(iv), the Eligible Employee may request that the matter be submitted directly to arbitration as provided

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 4(a)(iv) and the Company 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 Company 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s employment with a Participating Company terminates because he or she is eligible for or receiving
long-term or permanent disability benefits under the Company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:

(e) Review Panel Decision. Within the time prescribed in Section 9(d), the Review Panel shall give written notice of its decision to the applicant
and to the Company. In the event the Review Panel 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 Review Panel determines that the application for benefits should not have been
denied in whole or in part, the Company shall take appropriate remedial action as soon as reasonably practicable after receiving notice of the Review Panels decision.



(f) Section 4(a)(iv) Dispute. In the event that a dispute involving the application or interpretation of Section
4(a)(iv) is referred to the Review Panel as provided therein, the Review Panel 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 9.



(g) Rules And Procedures. The Review Panel 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 9. The Review Panel 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 8, (ii) has been notified by the Company 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 9, and (iv) has been notified that the Review Panel has denied the appeal. Notwithstanding the foregoing, if the Company or the Review Panel does not respond to an Eligible Employees claim or appeal within the
relevant time limits specified in Sections 8 and 9, the Eligible Employee may bring legal action for benefits under the Program pursuant to section 502(a) of ERISA.



SECTION 10. RESOLUTION OF DISPUTES INVOLVING SECTION 4.



(a) Arbitration Of Section 4 Dispute. Any dispute, controversy or question arising under Section 4 which is not
resolved by the decision of the Review Panel (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



22



---

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 Company, 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 4. The decision of the Arbitrator shall be final, conclusive and binding on all interested persons and no action at law or in equity involving the
application or interpretation of Section 4 shall be instituted other than to enforce the award of the Arbitrator.



SECTION 11. BASIS OF PAYMENTS TO AND FROM PROGRAM.



All benefits under the Program shall be paid by the Company. The Program shall be unfunded and benefits hereunder shall be paid only from the general
assets of the Company. 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 Company and the Eligible Employees with respect to any
assets of the Company. The Company 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 Company chooses to use for advance funding shall not cause the Program to be a
funded plan within the meaning of ERISA.

SECTION 12. 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 13. 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
14. SUCCESSORS AND ASSIGNS.



The Program shall be
binding on the Company, its successors and assigns, and any parent corporation of the Companys successors or assigns. Notwithstanding that the Program may be binding upon a successor or assign by operation of law, the Company 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 Company would be if no succession or assignment had taken place.



SECTION 15. 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 Company to the address set forth in Section 8(a), attention of its Secretary, and the case of the Eligible Employee to his or her last known address
as reflected in the records of the Company.
